The splicing factor SRSF1 emerges as a mater regulator of cell proliferation, displaying high expression in actively proliferative satellite cells (SCs). In SRSF1 knockout mice (KO) generated via MyoD-Cre, early mortality and muscle atrophy are observed during postnatal muscle growth. Despite these findings, the precise mechanisms through which SRSF1 loss influences SCs' functions and its role in muscle regeneration remain to be elucidated.
剪接因子 SRSF1 是细胞增殖的重要调节因子,在增殖活跃的卫星细胞(SC)中高表达。在通过 MyoD-Cre 产生的 SRSF1 基因敲除小鼠(KO)中,可以观察到出生后肌肉生长过程中的早期死亡和肌肉萎缩。尽管有这些发现,但SRSF1缺失影响卫星细胞功能的确切机制及其在肌肉再生中的作用仍有待阐明。

BackgroundTraditional metrics such as body mass index (BMI) and waist circumference (WC) fail to accurately assess the health outcomes associated with abdominal adiposity, because they neglect the intricacies of adipose tissue distribution. Notably, the variability in body composition scaled to height remains underexplored in Chinese demographics. This study introduces height‐normalised indices of abdominal adiposity using computed tomography (CT) scans and further assesses their associations with various health outcomes.MethodsIn a large, diverse Chinese population (n = 1054 healthy individuals; n = 1159 with dyslipidemia; n = 803 with diabetes; n = 1289 with cardio‐cerebrovascular diseases; n = 1108 with cancers; and n = 509 with abnormal bone mas), abdominal CT scans were performed and allometric growth model analyses were used to derive height‐normalised indices (body composition/heightβ). Logistic regression models assessed the associations between these indices and health outcomes.ResultsDistinct scaling powers were observed for visceral adipose tissue (VAT), subcutaneous adipose tissue (SAT) and total abdominal adipose tissue (TAT), as well as for sagittal diameter (SAD), with marked sex differences. Powers for VAT were 1.786 ± 1.270 for males and 1.274 ± 0.692 for females. Powers for SAT were 2.266 ± 0.856 for males and 1.656 ± 0.497 for females. Powers for TAT were 2.141 ± 0.967 for males and 1.438 ± 0.489 for females. Powers for SAD were 0.646 ± 0.217 for males and 0.678 ± 0.141 for females. After controlling for age, BMI and WC, VAT/heightβ, TAT/heightβ and SAD/heightβ retained their significantly positive associations with the odds of health outcomes, whereas SAT/heightβ did not.ConclusionsOur findings endorse the clinical utility of height‐normalised indices, particularly VAT/heightβ, TAT/heightβ and SAD/heightβ, in health outcomes assessment. These indices, grounded in robust empirical data, underscore the necessity of a nuanced approach in obesity‐related health evaluations, advocating for a departure from conventional methods like BMI.
背景身体质量指数(BMI)和腰围(WC)等传统指标无法准确评估与腹部脂肪相关的健康后果,因为它们忽视了脂肪组织分布的复杂性。值得注意的是,在中国人口统计学中,按身高缩放的身体成分变异性仍未得到充分研究。本研究通过计算机断层扫描(CT)引入了身高归一化的腹部脂肪指数,并进一步评估了这些指数与各种健康结果的关系。方法 在一个大规模、多样化的中国人群(健康人 1054 人;血脂异常者 1159 人;糖尿病患者 803 人;心脑血管疾病患者 1289 人;癌症患者 1108 人;骨质异常者 509 人)中,进行腹部 CT 扫描,并使用异速生长模型分析得出身高归一化指数(身体成分/身高β)。结果观察到内脏脂肪组织(VAT)、皮下脂肪组织(SAT)和总腹部脂肪组织(TAT)以及矢状径(SAD)具有不同的缩放能力,并存在明显的性别差异。男性 VAT 的功率为 1.786 ± 1.270,女性为 1.274 ± 0.692。男性的 SAT 功率为 2.266 ± 0.856,女性为 1.656 ± 0.497。男性的 TAT 功率为 2.141 ± 0.967,女性为 1.438 ± 0.489。男性的 SAD 功率为 0.646 ± 0.217,女性为 0.678 ± 0.141。在控制了年龄、体重指数和腹围之后,VAT/身高β、TAT/身高β和 SAD/身高β仍与健康结果的几率呈显著正相关,而 SAT/身高β则没有。这些指数以可靠的实证数据为基础,强调了在与肥胖相关的健康评估中采用细致入微的方法的必要性,主张摒弃 BMI 等传统方法。

BackgroundDynapenic obesity is a condition characterized by high adiposity levels combined with muscle dysfunction. Although high adiposity and muscle loss/dysfunction are thought to synergistically increase the risk of cardiovascular disease (CVD), few studies have addressed the association between dynapenic and sarcopenic obesity and CVD. We aimed to investigate the association of dynapenic obesity with incident CVD events using the data from a population‐based prospective longitudinal study in Japan.MethodsA total of 2490 community‐dwelling Japanese aged 40–79 years (42.5% males, mean age 57.7 ± 10.6 years) without a history of CVD were followed up for a median of 24 years. Handgrip strength was classified as low, medium, or high by age‐ and sex‐specific tertiles. Body mass index (BMI) levels were categorized as lean (<18.5 kg/m2), normal (18.5–24.9 kg/m2), or obese (≥25.0 kg/m2). Dynapenic obesity was defined as having both low handgrip strength and obesity. The outcomes were defined as the first‐ever development of CVD (defined as stroke or coronary heart disease). The hazard ratios (HRs) and their 95% confidence intervals (CIs) for the development of CVD were estimated using a Cox proportional hazards model, in which participants with high handgrip strength and normal BMI were used as a reference group. Mediation analyses used serum high‐sensitivity C‐reactive protein (hs‐CRP) and homeostatic model assessment for insulin resistance (HOMA‐IR) as mediators.ResultsDuring the follow‐up period, 482 participants developed CVD events (324 cases of stroke and 209 of coronary heart disease). The multivariable‐adjusted risk of CVD increased significantly among participants with dynapenic obesity compared with the reference group (HR 1.49, 95% CI 1.03–2.17). An analysis by age groups showed a further increase in the risk of CVD among participants with dynapenic obesity aged less than 65 years (HR 1.66, 95% CI 1.04–2.65). In mediation analyses for participants aged less than 65 years, serum hs‐CRP was shown to be a significant mediator explaining 13.8% of the association between dynapenic obesity and the development of CVD, while HOMA‐IR explained 12.2% of this relationship.ConclusionsDynapenic obesity was a significant risk factor for the development of CVD in a general Japanese population. This association was more pronounced among those aged <65 years. Inflammation, and possibly glucose metabolism, might partly mediate this association. Our findings suggest that preventing muscle dysfunction as well as appropriate weight control, especially in middle‐age, are important for preventing the development of CVD.
背景动态性肥胖是一种以高脂肪水平合并肌肉功能障碍为特征的疾病。虽然高脂肪和肌肉损失/功能障碍被认为会协同增加心血管疾病(CVD)的风险,但很少有研究探讨动态肥胖和肌肉疏松性肥胖与心血管疾病之间的关系。我们的目的是利用日本一项基于人群的前瞻性纵向研究的数据,调查动态肥胖与心血管疾病事件之间的关系。方法我们对 2490 名 40-79 岁(42.5% 为男性,平均年龄为 57.7 ± 10.6 岁)、无心血管疾病史的日本社区居民进行了中位数为 24 年的随访。手握力按年龄和性别分为低、中、高三级。体重指数(BMI)水平分为瘦(18.5 kg/m2)、正常(18.5-24.9 kg/m2)或肥胖(≥25.0 kg/m2)。动力性肥胖的定义是同时具有低握力和肥胖。结果定义为首次发生心血管疾病(定义为中风或冠心病)。心血管疾病发病的危险比(HRs)及其95%置信区间(CIs)是用Cox比例危险模型估算的,其中将手握力量大且体重指数正常的参与者作为参照组。结果在随访期间,482 名参与者发生了心血管疾病事件(324 例中风和 209 例冠心病)。与参照组相比,经多变量调整后,动态肥胖参与者的心血管疾病风险显著增加(HR 1.49,95% CI 1.03-2.17)。按年龄组进行的分析表明,65 岁以下的动态性肥胖参与者患心血管疾病的风险进一步增加(HR 1.66,95% CI 1.04-2.65)。在对年龄小于 65 岁的参与者进行的中介分析中,血清 hs-CRP 被证明是一个重要的中介因素,可解释动态肥胖与心血管疾病之间 13.8% 的关系,而 HOMA-IR 可解释这种关系的 12.2%。这种关联在 65 岁以上的人群中更为明显。炎症以及葡萄糖代谢可能是导致这种关联的部分原因。我们的研究结果表明,预防肌肉功能障碍以及适当控制体重,尤其是在中年时期,对于预防心血管疾病的发生非常重要。

The prediction of the risk of developing complications after colorectal surgery for colorectal carcinoma remains imprecise. Body composition measurements on a computed tomography (CT) scan can potentially contribute to a better preoperative risk assessment. The aim of this systematic review is to evaluate the evidence for the use of body composition measurements on CT scans to predict short-term complications after colorectal cancer surgery. A literature search (in PubMed, Embase and Web of Science) was performed up to 1 August 2022. Two researchers independently screened the articles, extracted data and assessed the quality of the studies using the Quality in Prognosis Studies tool. The primary outcome measure was the occurrence of complications within 30 days after surgery. Meta-analysis was conducted using a random-effects model to synthesize a pooled odds ratio (OR). The study protocol was registered in PROSPERO (CRD42021281010). Forty-five articles with a total of 16 537 patients were included. In total, 26 body composition measures were investigated: 8 muscle-related measures, 11 adipose tissue measures, 4 combined muscle and adipose tissue measures, and 3 other measures. These were investigated as potential predictors for more than 50 differently defined postoperative complications. Meta-analysis was only possible for two measurements and showed that higher amounts of visceral fat increase the risk of developing overall complications (OR: 2.52 [1.58-4.00], P < 0.0001) and anastomotic leakage (OR: 1.76 [1.17-2.65], P = 0.006). A wide variety of body composition measurements on preoperative CT scans have been investigated as a predictive factor for postoperative complications. Visceral fat appeared to be associated with overall complications and anastomotic leakage; however, the association is weak, and its clinical relevance or applicability is questionable. The current evidence is limited by methodological heterogeneity and the risk of bias. To improve comparability of results across studies and improve decision-making, future studies should use standardized methods for measuring body composition on CT scans, outcome definitions and statistical analyses.

Background: The association between perioperative changes in the skeletal muscle index (SMI) and colorectal cancer (CRC) outcomes remains unclear. We aim to explore perioperative change patterns of SMI and evaluate their effects on long-term outcomes in CRC patients.

Methods: This retrospective cohort study included Stage I-III CRC patients who underwent curative resection between 2012 and 2019. SMI at the third lumbar vertebra level was calculated using computed tomography scans. Optimal cut-off values for SMI were defined separately for males and females and classified as high or low preoperatively and at 3, 6, 9 and 12 months postoperatively. SMI status was further categorized into different perioperative SMI change patterns: highpre-highpost, highpre-lowpost, lowpre-highpost and lowpre-lowpost. The association with recurrence-free survival (RFS) and overall survival (OS) was examined using Cox proportional hazards models.

Results: A total of 2222 patients (median [interquartile range] age, 60.00 [51.00-68.00] years; 1302 (58.60%) men; 222 (9.99%) with preoperative low SMI) were evaluated. During a median follow-up of 60 months, 375 patients (16.88%) died, and 617 patients (27.77%) experienced a recurrence. Multivariate Cox model analysis showed that, compared to patients with highpre-highpost, those with highpre-lowpost (HR = 3.32, 95% CI: 1.60-6.51; HR = 2.54, 95% CI: 1.03-6.26; HR = 2.93, 95% CI: 1.19-7.19, all p < 0.05) had significantly worse RFS and OS (HR = 4.07, 95% CI: 1.55-10.69; HR = 4.78, 95% CI: 1.40-16.29; HR = 9.69, 95% CI: 2.53-37.05, all p < 0.05), at postoperative 6, 9 and 12 months, respectively. Patients with lowpre-lowpost were an independent prognostic factor for worse OS at postoperative 12 months (HR = 3.20, 95% CI: 1.06-9.71, p = 0.040). Patients with lowpre-highpost had similar risk of RFS compared to those with highpre-highpost at postoperative 3, 6 and 12 months (HR = 1.49, 95% CI: 0.75-2.98; HR = 1.05, 95% CI: 0.45-2.43; HR = 1.36, 95% CI: 0.31-6.06, all p > 0.05) and similar risk of OS at postoperative 3, 6, 9 and 12 months (all p > 0.05).

Conclusions: Patients with a high preoperative SMI that decline postoperatively have poor RFS and OS. Consistently low SMI also correlates with worse OS. Patients with low SMI but increased after resection are not an indicator of better prognosis. Routine measurement of postoperative, rather than preoperative, SMI is warranted. Patients with low SMI are at an increased risk for recurrence and death, especially within the first year after surgery.

背景:围手术期骨骼肌指数(SMI)的变化与结直肠癌(CRC)预后之间的关系仍不清楚。我们旨在探索围手术期骨骼肌指数的变化规律,并评估其对 CRC 患者长期预后的影响:这项回顾性队列研究纳入了 2012 年至 2019 年期间接受根治性切除术的 I-III 期 CRC 患者。使用计算机断层扫描计算第三腰椎水平的 SMI。分别为男性和女性定义了 SMI 的最佳临界值,并在术前和术后 3、6、9 和 12 个月时将其分为高或低。SMI 状态又被分为不同的围手术期 SMI 变化模式:术前高、术前低、术前低和术前低。采用 Cox 比例危险模型研究了无复发生存率(RFS)和总生存率(OS)的相关性:共评估了2222名患者(中位数[四分位数间距]年龄为60.00[51.00-68.00]岁;1302名(58.60%)男性;222名(9.99%)术前SMI较低)。在中位随访 60 个月期间,375 名患者(16.88%)死亡,617 名患者(27.77%)复发。多变量 Cox 模型分析显示,与高前高后患者相比,高前低后患者(HR = 3.32,95% CI:1.60-6.51;HR = 2.54,95% CI:1.03-6.26;HR = 2.93,95% CI:1.19-7.19,均为 P 前低后患者)是术后 12 个月 OS 较差的独立预后因素(HR = 3.20,95% CI:1.06-9.71,P = 0.040)。在术后3、6和12个月时,术前高密度低密度患者的RFS风险与术后高密度高密度患者相似(HR=1.49,95% CI:0.75-2.98;HR=1.05,95% CI:0.45-2.43;HR=1.36,95% CI:0.31-6.06,所有P>0.05),在术后3、6、9和12个月时,OS风险相似(所有P>0.05):结论:术前SMI较高而术后下降的患者RFS和OS较差。持续的低SMI也与较差的OS相关。SMI较低但切除术后升高的患者并非预后较好的指标。有必要对术后而非术前的 SMI 进行常规测量。低 SMI 患者复发和死亡的风险增加,尤其是在术后第一年内。

Background: ADCK genes encode aarF domain-containing mitochondrial kinases involved in coenzyme Q (CoQ) biosynthesis and regulation. Haploinsufficiency of ADCK2 in humans leads to adult-onset physical incapacity with reduced mitochondrial CoQ levels in skeletal muscle, resulting in mitochondrial myopathy and alterations in fatty acid β-oxidation. The sole current treatment for CoQ deficiencies is oral administration of CoQ10, which causes only partial recovery with postnatal treatment, underscoring the importance of early diagnosis for successful intervention.

Methods: We used Adck2 heterozygous mice to examine the influence of this gene on muscle structure, function and regeneration throughout development, growth and ageing. This investigation involved techniques including immunohistochemistry, analysis of CoQ levels, mitochondrial respiratory content, muscle transcriptome analysis and functional tests.

Results: We demonstrated that Adck2 heterozygous mice exhibit defects from embryonic development, particularly in skeletal muscle (1102 genes deregulated). Adck2 heterozygous embryos were 7% smaller in size and displayed signs of delayed development. Prenatal administration of CoQ10 could mitigate these embryonic defects. Heterozygous Adck2 mice also showed a decrease in myogenic cell differentiation, with more severe consequences in 'aged' mice (41.63% smaller) (P < 0.01). Consequently, heterozygous Adck2 mice displayed accelerated muscle wasting associated with ageing in muscle structure (P < 0.05), muscle function (less grip strength capacity) (P < 0.001) and muscle mitochondrial respiration (P < 0.001). Furthermore, progressive CoQ10 administration conferred protective effects on mitochondrial function (P < 0.0001) and skeletal muscle (P < 0.05).

Conclusions: Our work uncovered novel aspects of CoQ deficiencies, revealing defects during embryonic development in mammals for the first time. Additionally, we identified the gradual establishment and progression of the deleterious Adck2 mouse phenotype. Importantly, CoQ10 supplementation demonstrated a protective effect when initiated during development.

背景:ADCK 基因编码含 aarF 结构域的线粒体激酶,参与辅酶 Q(CoQ)的生物合成和调节。人类 ADCK2 的单倍体缺陷会导致骨骼肌线粒体 CoQ 水平降低,导致线粒体肌病和脂肪酸 β 氧化改变,从而导致成年后的身体机能丧失。目前治疗 CoQ 缺乏症的唯一方法是口服 CoQ10,但这种方法只能在出生后的治疗中导致部分恢复,因此强调了早期诊断对成功干预的重要性:我们利用 Adck2 杂合子小鼠来研究该基因在整个发育、生长和衰老过程中对肌肉结构、功能和再生的影响。这项研究涉及的技术包括免疫组织化学、CoQ 水平分析、线粒体呼吸含量、肌肉转录组分析和功能测试:结果:我们发现 Adck2 杂合子小鼠从胚胎发育开始就表现出缺陷,尤其是在骨骼肌方面(1102 个基因失调)。Adck2杂合子胚胎的体积小7%,并表现出发育延迟的迹象。产前服用 CoQ10 可减轻这些胚胎缺陷。杂合子 Adck2 小鼠的成肌细胞分化也出现下降,"老龄 "小鼠的后果更为严重(小了 41.63%)(P 10):我们的研究发现了 CoQ 缺乏的新方面,首次揭示了哺乳动物胚胎发育过程中的缺陷。此外,我们还发现了 Adck2 小鼠有害表型的逐步建立和发展过程。重要的是,在发育过程中补充 CoQ10 具有保护作用。

Background: The risk of sarcopenia in older adults with chronic kidney disease (CKD) not yet on dialysis is controversial. The aims of this study were to investigate the association among sarcopenia, diabetes and predialysis CKD and evaluate the impact of gender and ageing on the risk of sarcopenia statuses in older patients with predialysis CKD.

Methods: The participants aged ≥60 years old were recruited from the community of New Taipei City, Taiwan. Handgrip strength, appendicular skeletal muscle mass and the 6-m walk were measured. The diagnosis of sarcopenia was established based on the consensus of Asian Sarcopenia Working Group 2019. These older adults were categorised into G1, G2 and G3-5 according to the guidelines of Kidney Disease Improving Global Outcomes (KDIGO) after calculating the estimated glomerular filtration rate by the Modification of Diet in Renal Disease equation. The Chi-square test and ANOVA were used to estimate the difference of categorical and continuous variables, respectively. Polytomous logistic regression was employed to assess the odds ratio (OR) and 95% confidence intervals (CIs) of the sarcopenia status and sarcopenia-associated risk factors in the predialysis CKD patients. All tests were two-sided, and p < 0.05 was defined as statistical significance.

Results: Among the 3648 older adults (mean age: 71.9 ± 6.07 years), including 1701 males and 1947 females, 870 (23.9%), 94 (2.58%) and 48 (1.32%) had possible sarcopenia, sarcopenia and severe sarcopenia, respectively. After adjustment, the risk for possible sarcopenia, sarcopenia and severe sarcopenia significantly increased with ageing (OR = 1.11, 1.10 and 1.23; 95% CI = 1.10-1.13, 1.07-1.15 and 1.18-1.30, respectively) and male gender (OR = 2.26, 20.3 and 25.4; 95% CI = 1.87-2.73, 11.5-36.0 and 11.3-57.2, respectively). Compared with KDIGO G1, no significant association between KDIGO G3-5 and the statuses of sarcopenia was observed (OR = 0.97, 0.88 and 0.91; 95% CI = 0.75-1.26, 0.43-1.78 and 0.37-2.27, p = 0.821, 0.718, 0.838, for possible sarcopenia, sarcopenia and severe sarcopenia, respectively). Ageing and male gender indicated a significant risk for higher sarcopenia status in older patients with predialysis CKD (0.027-fold/year and 0.284-fold, respectively) (p < 0.0001).

Conclusions: This study illuminated the importance of the male sex and the ageing process on the risk of sarcopenia progression in patients with predialysis CKD. Early clinical screening and aggressive treatment for the prevention of higher sarcopenia status in advanced older male adults with predialysis CKD are recommended.

背景:尚未接受透析的慢性肾脏病(CKD)老年患者出现肌肉疏松症的风险存在争议。本研究旨在调查肌肉疏松症、糖尿病和透析前慢性肾脏病之间的关联,并评估性别和年龄对透析前慢性肾脏病老年患者肌肉疏松症风险的影响:方法:从台湾新北市社区招募年龄≥60 岁的参与者。方法:从台湾新北市社区招募年龄≥60 岁的参与者,测量他们的手握力、骨骼肌质量和 6 米步行距离。根据 2019 年亚洲肌肉疏松症工作组的共识,确定了肌肉疏松症的诊断。根据 "肾脏疾病改善全球结果"(KDIGO)的指导原则,用 "肾脏疾病饮食改良 "方程计算肾小球滤过率后,这些老年人被分为 G1、G2 和 G3-5 三类。采用卡方检验(Chi-square test)和方差分析(ANOVA)分别估计分类变量和连续变量的差异。多态逻辑回归用于评估透析前慢性肾脏病患者肌肉疏松症状态和肌肉疏松症相关风险因素的几率比(OR)和 95% 置信区间(CIs)。所有检验均为双侧检验,P 结果:在 3648 名老年人(平均年龄:71.9 ± 6.07 岁)中,包括 1701 名男性和 1947 名女性,分别有 870 人(23.9%)、94 人(2.58%)和 48 人(1.32%)可能患有肌肉疏松症、肌肉疏松症和严重肌肉疏松症。经调整后,随着年龄的增长(OR = 1.11、1.10 和 1.23;95% CI = 1.10-1.13、1.07-1.15 和 1.18-1.30)和男性性别的增加(OR = 2.26、20.3 和 25.4;95% CI = 1.87-2.73、11.5-36.0 和 11.3-57.2),可能出现肌少症、肌少症和严重肌少症的风险显著增加。与 KDIGO G1 相比,KDIGO G3-5 与肌肉疏松症状态之间未发现明显关联(OR = 0.97、0.88 和 0.91;95% CI = 0.75-1.26、0.43-1.78 和 0.37-2.27,P = 0.821、0.718 和 0.838,分别用于可能的肌肉疏松症、肌肉疏松症和严重的肌肉疏松症)。在透析前患有慢性肾脏病的老年患者中,年龄和男性性别显示出较高的肌肉疏松症风险(分别为 0.027 倍/年和 0.284 倍)(p 结论:本研究揭示了男性性别和衰老过程对透析前慢性肾脏病患者肌少症进展风险的重要性。建议对患有透析前慢性肾脏病的高龄男性患者进行早期临床筛查和积极治疗,以预防更严重的肌少症。

Background: Orbicularis oris muscle, the crucial muscle in speaking, facial expression and aesthetics, is considered the driving force for optimal lip repair. Impaired muscle regeneration remains the main culprit for unsatisfactory surgical outcomes. However, there is a lack of study on how different surgical manipulations affect lip muscle regeneration, limiting efforts to seek effective interventions.

Methods: In this study, we established a rat lip surgery model where the orbicularis oris muscle was injured by manipulations including dissection, transection and stretch. The effect of each technique on muscle regeneration was examined by histological analysis of myogenesis and fibrogenesis. The impact of tensile force was further investigated by the in vitro application of mechanical strain on cultured myoblasts. Transcriptome profiling of muscle satellite cells from different surgical groups was performed to figure out the key factors mediating muscle fibrosis, followed by therapeutic intervention to improve muscle regeneration after lip surgeries.

Results: Evaluation of lip muscle regeneration till 56 days after injury revealed that the stretch group resulted in the most severe muscle fibrosis (n = 6, fibrotic area 48.9% in the stretch group, P < 0.001, and 25.1% in the dissection group, P < 0.001). There was the lowest number of Pax7-positive nuclei at Days 3 and 7 in the stretch group (n = 6, P < 0.001, P < 0.001), indicating impaired satellite cell expansion. Myogenesis was impaired in both the transection and stretch groups, as evidenced by the delayed peak of centrally nucleated myofibers and embryonic MyHC. Meanwhile, the stretch group had the highest percentage of Pdgfra+ fibro-adipogenic progenitors infiltrated area at Days 3, 7 and 14 (n = 6, P = 0.003, P = 0.006, P = 0.037). Cultured rat lip muscle myoblasts exhibited impaired myotube formation and fusion capacity when exposed to a high magnitude (ε = 2688 μ strain) of mechanical strain (n = 3, P = 0.014, P = 0.023). RNA-seq analysis of satellite cells isolated from different surgical groups demonstrated that interleukin-10 was the key regulator in muscle fibrosis. Administration of recombinant human Wnt7a, which can inhibit the expression of interleukin-10 in cultured satellite cells (n = 3, P = 0.041), exerted an ameliorating effect on orbicularis oris muscle fibrosis after stretching injury in surgical lip repair.

Conclusions: Tensile force proved to be the most detrimental manoeuvre for post-operative lip muscle regeneration, despite its critical role in correcting lip and nose deformities. Adjunctive biotherapies to regulate the interleukin-10-mediated inflammatory process could facilitate lip muscle regeneration under conditions of high surgical tensile force.

背景:口轮匝肌是说话、面部表情和美观的关键肌肉,被认为是最佳唇部修复的动力。肌肉再生障碍仍是手术效果不理想的罪魁祸首。然而,目前缺乏对不同手术操作如何影响唇肌再生的研究,从而限制了寻求有效干预措施的努力:在这项研究中,我们建立了一个大鼠唇部手术模型,通过解剖、横断和拉伸等操作损伤口轮匝肌。通过对肌肉生成和纤维生成的组织学分析,研究了每种技术对肌肉再生的影响。通过对培养的肌母细胞施加体外机械应变,进一步研究了拉伸力的影响。对不同手术组的肌肉卫星细胞进行了转录组分析,以找出介导肌肉纤维化的关键因素,然后进行治疗干预,以改善唇部手术后的肌肉再生:损伤后 56 天的唇部肌肉再生评估显示,拉伸组的肌肉纤维化程度最严重(n = 6,拉伸组的纤维化面积为 48.9%,第 3、7 和 14 天的 P + 纤维脂肪原浸润面积(n = 6,P = 0.003、P = 0.006、P = 0.037))。培养的大鼠唇肌肌母细胞在暴露于高强度(ε = 2688 μ应变)机械应变时,肌管形成和融合能力受损(n = 3,P = 0.014,P = 0.023)。从不同手术组分离的卫星细胞的RNA-seq分析表明,白细胞介素-10是肌肉纤维化的关键调节因子。重组人 Wnt7a 可抑制白细胞介素-10 在培养的卫星细胞中的表达(n = 3,P = 0.041),对唇修复手术中拉伸损伤后的眼轮匝肌纤维化有改善作用:结论:尽管拉伸力在矫正唇部和鼻部畸形中起着至关重要的作用,但事实证明拉伸力是最不利于术后唇部肌肉再生的操作。调节白细胞介素-10介导的炎症过程的辅助生物疗法可在高手术拉力条件下促进唇肌再生。

Background: Cancer cachexia complicates advanced non-small cell lung cancer (NSCLC); however, it remains unclear how often cachexia occurs and how it affects the course of chemotherapy in patients receiving first-line systemic therapy.

Methods: We conducted a multicentre, prospective observational study and enrolled previously untreated NSCLC patients with Eastern Cooperative Oncology Group Performance Status (ECOG PS) of 0-2 and cachexia between September 2020 and September 2021. The primary outcome measure was the trends in the Functional Assessment of Anorexia/Cachexia Treatment and Anorexia/Cachexia Subscale [FAACT (A/CS)] scores by cohort. Secondary outcome measures included the incidence of cachexia before the initiation of first-line systemic therapy, quality of life (QOL) measures, body weight (BW) changes, and efficacy and safety of first-line systemic therapy.

Results: A total of 887 consecutive patients with previously untreated advanced NSCLC and ECOG PS of 0-2 who were initiated on first-line systemic therapy were evaluated. A total of 281 patients (31.7%) experienced BW loss consistent with the criteria of cachexia, and 186 were evaluated for QOL, BW and outcome measurements. Overall, 180/186 patients received first-line systemic therapy. Cohort 1 (targeted therapy), cohort 2 [cytotoxic chemotherapy (CTx) ± immune checkpoint inhibitors (ICIs)] and cohort 3 (ICIs) included 42, 98 and 40 patients, respectively. There were significant variations in QOL trends by cohort, with chemotherapy-associated emesis affecting early appetite-related QOL. The change in the FAACT (A/CS) score at 1 week from baseline was worse in cohort 2 (the least square mean change ± standard error: -3.0 ± 0.9) than in cohorts 1 (1.6 ± 1.2, p = 0.003) and 3 (1.8 ± 1.0, p = 0.002); meanwhile, the change at 6 weeks was worse in cohort 1 (-1.5 ± 1.2) than in cohorts 2 (3.6 ± 0.9, p = 0.001) and 3 (3.5 ± 1.1, p = 0.004). BW reduction was observed in all cohorts within 6 weeks of therapy initiation. The targeted therapy cohort demonstrated superior progression-free survival (PFS) and overall survival (OS) to CTx ± ICIs cohort or ICIs cohort (median PFS was 9.7 months, 6.3 months, 3.1 months, in cohort 1, 2, 3, respectively (cohort 1 vs. cohort 2: HR, 0.58, p = 0.018; cohort 1 vs. cohort 3: HR, 0.41, p = 0.001); median OS was not reached, 15.8 months, 9.9 months, respectively (cohort 1 vs. cohort 2: HR, 0.52, p = 0.033; cohort 1 vs. cohort 3: HR, 0.37, p = 0.003).

Conclusions: Approximately 1/3 patients with previously untreated advanced NSCLC have cachexia. Appetite-related QOL trends vary based on the type of first-line systemic therapy in cachectic NSCLC patients, and the PFS and OS of these patients seemed to be shorter.

背景:癌症恶病质是晚期非小细胞肺癌(NSCLC)的并发症之一:癌症恶病质是晚期非小细胞肺癌(NSCLC)的并发症;然而,目前仍不清楚恶病质发生的频率以及恶病质如何影响接受一线系统治疗患者的化疗疗程:我们开展了一项多中心、前瞻性观察研究,并在 2020 年 9 月至 2021 年 9 月期间招募了既往未接受过治疗、东部合作肿瘤学组表现状态(ECOG PS)为 0-2 且有恶病质的 NSCLC 患者。主要结局指标是各组群厌食/恶病质治疗功能评估和厌食/恶病质分量表[FAACT (A/CS)]得分的变化趋势。次要结局指标包括一线系统疗法开始前的恶病质发生率、生活质量(QOL)指标、体重(BW)变化以及一线系统疗法的疗效和安全性:共对 887 例既往未接受过治疗、ECOG PS 为 0-2 且开始接受一线系统治疗的晚期 NSCLC 患者进行了评估。共有 281 名患者(31.7%)出现了符合恶病质标准的体重减轻,186 名患者接受了 QOL、体重和结果测量评估。总体而言,180/186 名患者接受了一线系统治疗。队列1(靶向治疗)、队列2[细胞毒性化疗(CTx)±免疫检查点抑制剂(ICIs)]和队列3(ICIs)分别包括42、98和40名患者。各组群的 QOL 趋势存在明显差异,化疗相关的呕吐影响了早期食欲相关的 QOL。与基线相比,组群2中1周时的FAACT(A/CS)评分变化(最小平方均值变化±标准误差:-3.0 ± 0.9)比组群1(1.6 ± 1.2,P = 0.003) 和 3 (1.8 ± 1.0, p = 0.002);同时,6 周时的变化情况,队列 1 (-1.5 ± 1.2) 比队列 2 (3.6 ± 0.9, p = 0.001) 和队列 3 (3.5 ± 1.1, p = 0.004) 更差。在开始治疗的 6 周内,所有队列均观察到 BW 下降。靶向治疗队列的无进展生存期(PFS)和总生存期(OS)优于 CTx ± ICIs 队列或 ICIs 队列(队列 1、2、3 的中位 PFS 分别为 9.7 个月、6.3 个月、3.1 个月(队列 1 vs. 队列 2:HR,0.001))。队列1 vs. 队列2:HR,0.58,p = 0.018;队列1 vs. 队列3:HR,0.41,p = 0.001);未达到中位OS,分别为15.8个月和9.9个月(队列1 vs. 队列2:HR,0.52,p = 0.033;队列1 vs. 队列3:HR,0.37,p = 0.003):结论:约1/3既往未经治疗的晚期NSCLC患者有恶病质。结论:约有1/3的既往未接受过治疗的晚期NSCLC患者存在恶病质,根据恶病质NSCLC患者一线系统治疗的类型不同,食欲相关的QOL趋势也不同,而且这些患者的PFS和OS似乎更短。
