Background: Soluble P-selectin (sP-selectin) is associated with risk factors for cardiovascular disease (CVD) but this association has not been evaluated in patients with schizophrenia. This study primarily evaluated the association of sP-selectin with plasma lipids and nitrite (NO2-) respectively in overweight/obese adults with schizophrenia.
Methods: One-hundred and six patients with schizophrenia (mean age 32.9 years; 71.60% male) were recruited from a psychiatric hospital. Participants completed a structured interview and provided a fasting blood sample. Body mass index (BMI) was used to divide the sample into normal weight and overweight/obese groups. Pearson's and partial correlation coefficients (controlling for age, sex, race, education, and inflammation) were calculated to examine the association of sP-selectin with plasma lipids, and NO2- in the overweight/obese patients (primary analysis), as well as in the normal weight patients and the total sample (exploratory analyses).
Results: After controlling for potential confounders, sP-selectin positively correlated with triglycerides (r = 0.38, p = 0.01) and NO2- (r = 0.40, p < 0.01) in the overweight/obese group only.
Conclusions: Future longitudinal studies should evaluate the utility of sP-selectin as a biomarker of CVD in overweight/obese adults with schizophrenia (for example, by relating sP-selectin to incidence of cardiovascular events).
背景:可溶性p -选择素(sp -选择素)与心血管疾病(CVD)的危险因素相关，但这种关联尚未在精神分裂症患者中得到评估。本研究主要评估了sp -选择素与超重/肥胖成人精神分裂症患者血脂和亚硝酸盐(NO2-)的关系。方法:106例精神分裂症患者(平均年龄32.9岁;(71.60%男性)从精神病院招募。参与者完成了一个结构化的访谈，并提供了空腹血液样本。使用身体质量指数(BMI)将样本分为正常体重组和超重/肥胖组。计算Pearson和偏相关系数(控制年龄、性别、种族、教育程度和炎症)，以检验超重/肥胖患者(初步分析)以及正常体重患者和总样本(探索性分析)中sp -选择素与血浆脂质和NO2-的关系。结果:在控制潜在混杂因素后，sP-selectin仅在超重/肥胖组与甘油三酯(r = 0.38, p = 0.01)和NO2- (r = 0.40, p < 0.01)呈正相关。结论:未来的纵向研究应该评估sp -选择素作为超重/肥胖精神分裂症成人CVD生物标志物的效用(例如，通过将sp -选择素与心血管事件发生率联系起来)。

Abstract Objective This meta-analysis aims to investigate the diagnostic performance of serum homocysteine (Hcy) as a biomarker for diabetic nephropathy (DN). Methods Clinical publications relevant to serum Hcy level and DN were systematic searched in the electronic databases of; Pubmed, Cochrane Library, Embase, Web of science, CNKI and CBM. The diagnostic data from each included original study was extracted and pooled by the effect size of diagnostic sensitivity, specificity, positive likely hood ratio (+LR), negative likely hood ratio (-LR), diagnostic odds ratio (DOR) and area under the symmetric ROC curve (AUC). Results 18 publications relevant to serum Hcy and DN were included in the meta-analysis. The I2 test demonstrated significant statistical heterogeneity across the 18 studies for the effect size of diagnostic. The pooled diagnostic sensitivity, specificity, +LR, -L, DOR, AUC were 0.76 (95%CI: 0.74-0.78), 0.84 (95%CI:0.82-0.86), 5.05 (95%CI:3.52-7.24), 0.27 (95%CI:0.19-0.39), 21.68 (95% CI:11.15to 42.14) and 0.90 respectively in the random effect model. Conclusion Based on the present publications, serum Hcy is a promising serological marker for DN diagnosis.

Abstract Objective Folate deficiency is closely related to the occurrence of human tumors and plays an important role in cell growth, differentiation, repair, and host defense. We studied the effects of folic acid on the apoptosis of breast cancer cells (MDA-MB-231) and on the activity of the PTEN/AKT/P53 signaling pathway in breast cancer cells. Methods Breast cancer cells (MDA-MB-231) were treated with folate alone or in combination with a PTEN specific inhibitor, SF1670. Cell viability was detected by a MTT assay, and the expression levels of apoptosis-related proteins and PTEN/AKT/P53 signaling pathway were detected via Western blot analysis. Rate of apoptosis was measured via cytometry. Results Folic acid inhibited the cell viability of MDAMB-231 cells and the expressions of Bcl-2 and p-AKT proteins and upregulate the expression of Bax, PTEN, and P53 proteins, thereby inducing apoptosis in these cells. SF1670 treatment inhibited the expressions of Bcl-2 and p-AKT protein and upregulate Bax, PTEN, and P53 protein expression. Conclusion Folic acid has cytotoxic effects on MDAMB-231 cells and can induce apoptosis by targeting the PTEN/AKT/P53 signaling pathway.

Abstract Objective To investigate the correlation between serum homocysteine (Hcy), Galectin-3 concentration and atrial structural remodeling in atrial fibrillation (AF) patients. Methods Twenty-five patients with persistent atrial fibrillation (PeAF), 24 patients with paroxysmal atrial fibrillation (PaAF) and 23 healthy controls were included in the present work. All subjects received an echocardiography examination. Serum concentration of Hcy and Galectin-3 were also examined by Enzyme Linked Immunosorbent Assay (ELISA). Results Echocardiography examination demonstrated that there were significant differences for LAD (p=0.002), LVEF (p=0.005) and LVAI (p=0.0001) between the control, PaAF and PeAF groups. However, LVSD and LVDD were not significantly different between the three groups (pall>0.05). There was a significant positive correlation between LAVI and serum Hcy level in both PaAF (rpearson=0.49, p=0.016) and PeAF (rpearson=0.51, p=0.009) groups. The correlation between LAVI and serum Galectin-3 concentration was also statistically significant for PaAF (rpearson=0.54, p=0.006) and PeAF (rpearson=0.60, p=0.001) groups. Using serum Hcy as reference, diagnostic sensitivity and specificity were calculated as 72.00 (95%CI: 50.61-87.93) and 62.50 (95%CI: 40.59-81.20), respectively, with an AUC of 0.68 for PaAF and PeAF. For serum Galectin-3, the sensitivity and specificity values were 64.00 (95%CI:42.52-82.03) and 66.67 (95%CI:44.68-84.37), respectively, with an AUC of 0.68. Conclusion: Serum Hcy and Galectin-3 were elevated in AF patients and thus may be potential markers of atrial structural remodeling. However, the diagnostic efficacy of PeAF from PaAF was limited by low AUC values.

Abstract Objective The aim of the present work was to evaluate the folate-receptor 1 (FOLR1) expression in cervical squamous cell carcinoma and its clinical significance. Methods FOLR1 mRNA expression level was detected in the cancer genome atlas (TCGA) database for multiple carcinomas. The FOLR1 mRNA relative expression between tumor tissue and normal cervix tissue of the cervical squamous cell cancer patients was compared by the online data analysis tool of GEPIA. The overall survival (OS) and progression free survival (PFS) between the FOLR1 high and low expression groups were compared by the log-rank test. Thirty one cervical squamous cancer patients and 20 healthy controls were included in and tested for serum FOLR1 protein level detection. Eighty one cervical squamous cell cancer patients who received surgery were included for FOLR1 protein expression detected by immunohistochemistry assay (IHC). The correlation between FOLR1 protein expression and patients’ clinical features was analyzed. Results FOLR1 mRNA was up-regulated in tumor tissue compared to corresponding normal cervical tissue of cervical squamous cell carcinoma. Top 20 genes interacted with FOLR1 was identified through the network with the edges of 146. UBXN10 (r=0.668, P<0.01) and GBP6 (r-=0.606, P<0.01) were the top 2 genes that most correlated with FOLR1. The serum level of FR-α (FOLR1 coding protein) were 275.50±83.79 and 161.70±66.62 (ng/L) for the cervical cancer and healthy control subjects respectively with significant statistical difference (P<0.05). Using the serum FR-α as serological marker for cervical cancer detection, the diagnostic sensitivity, specificity and AUC were 80.0% (58.40% to 91.93%), 80.65% (63.72% to 90.81%) and 0.85(95%CI:0.74-0.96), respectively. Immunohistochemical assay indicated that of the 81 cancer tissue samples, 45 (55.6%) was FOLR1 protein positive. FOLR1 protein positive expression rate in FIGO stage Ⅲ/Ⅳ was significant higher than in the stage Ⅰ/Ⅱ with statistical difference (P<0.05). The progression free survival (PFS) was significant different between FOLR1 high and low expression group (HR=2.48, 95%CI:1.1-5.58, P=0.023). However, the overall survival (OS) was not statistical different between the two groups (HR=1.34, 95%CI:0.84-2.15, P=0.22). Conclusion: FOLR1 was up-regulated in both serum and cancer tissue of cervical squamous cell carcinoma which may act as diagnostic and prognostic maker for cervical squamous cell cancer.

Abstract In patients with metastatic melanoma the advent of targeted therapy and immune checkpoint inhibitors has transformed the management of advanced and metastatic disease, resulting in improved outcomes. Neopterin is a biomarker of immune activation increased in cancer as well as in other conditions associated with immune activation. We present a case of a patient with advanced metastatic melanoma responding to the combination targeted therapy with dabrafenib and trametinib. The treatment was complicated by a fever that was accompanied by a marked rise in serum and urinary neopterin concentrations. Present case report illustrates not only the efficacy of combined targeted therapy, but also the utilization of neopterin measurements in the diagnosis and monitoring of pyrexia in patients with metastatic malignant melanoma.

Abstract Objective To investigate the clinical efficacy of 5-hydroxytryptamine 3 (5-HT3) receptor antagonists in reducing propofol injection pain, postoperative nausea/ vomiting, and shivering through pooling the available published data. Methods Prospective randomized clinical studies relevant to 5-HT3 receptor antagonists in reducing propofol injection pain published before June 2019 were identified from four electronic databases, Pubmed, the Cochrane central register of controlled trials, EMBASE and Wanfang. The incidence of propofol injection pain, postoperative nausea/vomiting, and shivering in patients after 5-HT3 receptor antagonists were compared to relevant control groups by pooling the individual data through random or fixed-effect models. The publication bias was assessed by funnel plot and Egger’s line regression test. Results After screening, a total of 19 publications relevant to 5-HT3 receptor antagonists in reducing propofol injection pain and prevention of postoperative nausea/vomiting or shivering were included for analysis. The pooled results demonstrated that 5-HT3 receptor antagonists could significantly reduce the total propofol injection pain compared to placebo (RR=0.49, 95%CI:0.45-0.54, P<0.05). For mild propofol injection pain, there was no statistical difference between 5-HT3 receptor antagonists and control groups (RR=1.07,95%CI:0.89-1.29, P>0.05). However, for moderate (RR=0.37, 95%CI: 0.31-0.46, P<0.05) and severe (RR=0.19, 95%CI:0.14-0.27, P<0.05) propofol injection pain, the incidence in 5-HT3 receptor antagonists was significantly lower than that of control groups. The pooled results also indicated that incidence of postoperative nausea/vomiting (RR=0.28, 95%CI:0.17-0.44, P<0.05) and postoperative shivering (RR=0.33, 95%CI:0.23-0.48, P<0.05) were significantly reduced in 5-HT3 receptor antagonists group compared to control group with a statistical difference. Conclusion: In this meta-analysis, 5-HT3 receptor antagonists effectively reduced propofol injection pain, postoperative nausea/vomiting, and shivering.

Abstract Background To evaluate sulfentanyl combined with dexmedetomidine hydrochloride on postoperative analgesia in patients who received video-assisted thoracic surgery (VATS) and its effects on serum norepinephrine (NE), dopamine (DA), 5-hydroxytryptamine (5-HT), and prostaglandin (PGE2). Material and Methods Ninety-nine non-small cell lung cancer (NSCLC) patients who received VATS were included in the study. All the patients received intravenous inhalation compound anesthesia. Of the 99 cases, 49 subjects (control group) received sulfentanyl for patient controlled intravenous analgesia (PICA) and other 50 cases (experiment group) received sulfentanyl combined with dexmedetomidine hydrochloride for PICA after operation of VATS. The analgesic effects of the two groups were evaluated according to Visual Analogue Scales (VAS) and the Bruggrmann Comfort Scale (BCS). The serum pain mediator of NE, DA, 5-HT, and PGE2 were examined and compared between the two groups in the first 24 h post-surgery. Results The VAS scores for the experiment group were significant lower than that of control group on the time points of 8, 16, and 24 h post-surgery (pall<0.05), and the BCS scores of the experiment group in the time points of 8, 16, and 24 h were significantly higher than that of controls (p<0.05). However, the VAS and BCS scores were not statistical differently in the time point of 1, 2, and 4 h post-surgery (pall>0.05). The mean sulfentanyl dosage was 63.01 ± 5.14 μg and 67.12 ± 6.91 μg for the experiment and control groups respectively with significant statistical difference (p<0.05). The mean analgesic pump pressing times were 4.30 ± 1.31 and 5.31 ± 1.46 for experiment and control groups respectively with significant statistical difference (p<0.05). The serum NE, DA, 5-HT, and PGE2 levels were significantly lower in the experimental group compared to that of control group in the time point of 12 h post-surgery (pall<0.05). The side effects of nausea, vomiting, delirium, rash, and hypotension atrial fibrillation were not statistically different between the two groups (pall>0.05). Conclusion Patient controlled intravenous analgesia of sulfentanyl combined with dexmedetomidine hydrochloride was effective in reducing the VAS score and serum pain mediators in NSCLC patients who received VAST.

Abstract Background: To investigate the clinical value of serum homocysteine (Hcy), folate, and ultrasonography detection of yolk sac in predicting the outcome of threatened abortion.Methods: Ninety-eight pregnant women within 12 weeks of gestation were included in the study. Of these subjects, 29 presented with threatened abortion and were considered the case group (n=29). The other 69 subjects showed as a normal pregnancy were the control group (n=69). The case group was followed up with at 28 weeks of gestation, and further divided into inevitable abortion group (IA, n=9) and successful fetus protection group (SFP, n=20). The yolk sacs of the included cases were measured by ultrasonography. The serum Hcy and folate levels of the included cases were measured by an enzyme cycling assay and chemiluminescent immunoassay, respectively. The yolk sac visualization rate and serum Hcy and folate levels were compared between the two case groups and used as a predicting reference for the outcome of threatened abortion. Results: The yolk sac visualization rates detected by ultrasonography were 97.1% (67/69) for the control group and 69.0% (20/29) for the threatened abortion group, with a statistical difference (p<0.05). For the IA and SFP groups, the visualization rates were 22.2% (2/9) and 90.0% (18/20) respectively, with a statistical difference (p<0.05). The serum Hcy levels in the threatened abortion group were significant elevated compared with control group (6.1±2.0 μmol/L vs 4.5±1.3 μmol/L), with a statistical difference (p<0.05). However, the serum levels of folat in the threatened abortion group were significantly decreased compared with the control group (15.5±4.2 nmol/L vs 19.1±4.7 nmol/L), with a statistical difference (p<0.05). The serum levels of Hcy and folate were 7.5±1.7 μmol/L and 12.7±4.2 nmol/L for the IA group, which were statistically different compared to the SFP group (p<0.05). The predictive sensitivity for the outcome of threatened abortion based on serum Hcy and folate levels were 85.0% and 75.0%, with a predictive specificity of 66.7% and 88.9% respectively. Conclusion: Serum Hcy and folate levels were quite different in threatened abortion pregnant woman compared to the control group. Serum Hcy and folate level detection combined with ultrasonography detection of yolk sac can provide useful information for threatened abortions
摘要背景:探讨血清同型半胱氨酸(Hcy)、叶酸及卵黄囊超声检测对先兆流产结局的预测价值。方法:98例妊娠12周以内的孕妇纳入研究。在这些受试者中，29例出现先兆流产，被认为是病例组(n=29)。其余69例正常妊娠者为对照组(n=69)。病例组于妊娠28周进行随访，并进一步分为不可流产组(IA, n=9)和保胎成功组(SFP, n=20)。超声检查各组卵黄囊。采用酶循环法和化学发光免疫法分别测定血清Hcy和叶酸水平。比较两组患者卵黄囊显影率、血清Hcy和叶酸水平，并以此作为先兆流产结局的预测参考。结果:对照组和先兆流产组卵黄囊显像率分别为97.1%(67/69)和69.0%(20/29)，差异有统计学意义(p<0.05)。IA组和SFP组的显像率分别为22.2%(2/9)和90.0%(18/20)，差异有统计学意义(p<0.05)。先兆流产组血清Hcy水平显著高于对照组(6.1±2.0 μmol/L vs 4.5±1.3 μmol/L)，差异有统计学意义(p<0.05)。先兆流产组血清叶酸水平明显低于对照组(15.5±4.2 nmol/L vs 19.1±4.7 nmol/L)，差异有统计学意义(p<0.05)。IA组血清Hcy和叶酸水平分别为7.5±1.7 μmol/L和12.7±4.2 nmol/L，与SFP组比较差异有统计学意义(p<0.05)。血清Hcy和叶酸水平对先兆流产结局的预测敏感性分别为85.0%和75.0%，预测特异性分别为66.7%和88.9%。结论:先兆流产孕妇血清Hcy和叶酸水平与对照组有较大差异。血清Hcy和叶酸水平检测结合卵黄囊超声检查可为先兆流产提供有用信息

Abstract Background The aim of this study was to investigate serum neopterin levels in patients with acute pancreatitis (AP) and its predictive value for mortality in cases of severe acute pancreatitis (SAP). Methods Eighty-two patients with confirmed acute pancreatitis (AP) were included and divided into two groups, mild acute pancreatitis (MAP, n=51) and severe acute pancreatitis (SAP, n=31) according to severity of disease. From the SAP group, 8 cases went on to develop multiple organ dysfunction syndrome (MODS) and 6 subsequently died. Thirty healthy subjects from routine medical examination were included as the control group. The neopterin serum concentrations were determined and compared between groups. Results Serum neopterin concentrations from control, MAP, SAP, SAP_Non-MODS, MODS_survival and MODS_death groups were 6.85±2.42 (nmol/L), 0.91±4.83(nmol/L), 33.11±11.67(nmol/L), 30.39±9.97(nmol/L), 36.40±4.48(nmol/L) and 41.75±15.64(nmol/L) respectively, with statistical significant difference (p<0.05). The sensitivity and specificity for mortality risk were 66.67% (95%CI:22.28-95.67%) and 88.00%(95%CI:68.78-97.45%) respectively, with area under the ROC curve (AUC) of 0.71(95%CI:0.50-0.9), under the cut off value of 40.18. Conclusion: Serum neopterin levels in patients with acute pancreatitis were significantly elevated and correlated with the severity of disease. Neopterin may also be used a serological biomarker of mortality risk in patients with SAP.
