Background

Traditional Chinese Medicine (TCM) Cuscutae semen (SC, Tusizi from Cuscuta chinensis Lam.) and Lycii fructus (FL, Gouqi from Lycium barbarum L.), are also used as a herb pair (SC-FL) to treat various ailments, including spermatogenic dysfunction (SD), a disease responsible for low fertility in males.

Objective

Herein, we will further determine the bioactive components, component targets and partial molecular mechanisms of the herb pair for the treatment of SD.

Methods

We employed the traditional Chinese medicine systems pharmacology database in combination with Ultra high performance liquid chromatography (UHPLC) analysis to analyze the active ingredients of the SC-FL herbal pair and explore its possible targets and underlying mechanism in treatment of spermatogenic dysfunction (SD). Moreover, we used a Sprague-Dawley rat model, generated by using glucosides of Tripterygium wilfordii (GTW), to evaluate the effect of SC-FL and the underlying mechanism on SD and reliability of certain key targets and pathways obtained from the pharmacology analysis.

Results

We identified 56 active ingredients in SC-LF affecting 41 overlapping gene signals that influenced SD treatment outcomes. 262 Gene Ontology (GO) terms and 170 pathways were yielded under analyses of Gene Ontology, Kyoto Encyclopedia of Gene and Genome pathway from which we predicted that cell proliferation and apoptosis were the primary biological processes (BP) involved in the treatment of SD by SC-LF. The results showed that SC-FL treatment significantly improved the testicular organ coefficient along with sperm count and motility, while reduced testicular damage and testicular tissue cell apoptosis in SD model. Mechanistically, SC-FL significantly upregulated the expression levels of anti-apoptotic proteins AR and BCL2 and downregulated those of pro-apoptotic proteins BAD, BAX, cleaved caspase 3, and CASP3.

Conclusion

Collectively, these results indicated that SC-FL elicited a protective effect by potentially regulating apoptosis, thus suggesting that it will represent an effective reagent for male infertility.

中药Cuscutae semen (SC, Tusizi from Cuscuta chinensis Lam.)和Lycii fructus (FL,枸杞from Lycium barbarum L.)也被用作草药对(SC-FL)来治疗各种疾病,包括生精功能障碍(SD),一种导致男性低生育能力的疾病。目的进一步确定该中药对治疗SD的生物活性成分、作用靶点及部分分子机制。方法采用中药系统药理学数据库,结合超高效液相色谱(UHPLC)分析,对SC-FL中药对的有效成分进行分析,探讨其治疗生精功能障碍(SD)的可能靶点和作用机制。此外,我们使用雷公藤(雷公藤)的葡萄糖苷建立了Sprague-Dawley大鼠模型,以评估SC-FL对SD的作用及其潜在机制,以及药理学分析得出的某些关键靶点和通路的可靠性。结果我们在SC-LF中鉴定出56种有效成分,影响41种影响SD治疗结果的重叠基因信号。通过对基因本体、京都基因和基因组通路百科全书的分析,获得262个基因本体(GO)术语和170个通路,预测SC-LF治疗SD的主要生物学过程是细胞增殖和细胞凋亡。结果表明,SC-FL处理显著提高SD模型大鼠睾丸脏器系数、精子数量和活力,减少睾丸损伤和睾丸组织细胞凋亡。机制上,SC-FL显著上调抗凋亡蛋白AR和BCL2的表达水平,下调促凋亡蛋白BAD、BAX、cleaved caspase 3和CASP3的表达水平。综上所述,SC-FL可能通过调控细胞凋亡而发挥保护作用,是一种治疗男性不育症的有效试剂。

Background

The efficacy of Drimia calcarata against the human cervical cancer remains unexplored and less understood.

Objective

The present study focused on investigating the cytotoxic effect of D. calcarata bulb extracts on cervical cancer cells.

Methods

The growth inhibitory effects of D. calcarata extracts were determined using the MTT, Ki67 and PI3K Activation assays. Apoptosis induction was assessed using fluorescence microscopy, the Muse Cell Analyser and gene expression analysis by RT-PCR. The cytotoxicity of the fractions was evaluated using MTT assay and the apoptosis induction using Muse Cell Analyser.

Results

Both methanol extract (ME) and water extract (WE) showed safety against noncancerous KMST-6 and HEK-293 cells. The extracts exhibited anticancer activity against HeLa, with no significant cytotoxic effect against the Ca-Ski cells. The WE increased the Ki67 positive Ca-Ski population, while both ME and WE arrested HeLa cells at G2/M phase, and Ca-Ski cells in G0/G1 phase. AO/EB staining, Annexin V and Caspase 3/7 Activation revealed that the extracts significantly induced apoptosis in HeLa cells. In HeLa cells, the ME downregulated TP53 variants, while WE upregulated both TP53 variants in HeLa cells. Both extracts decreased the STAT5A and STAT5B mRNA expression in HeLa cells; however, these extracts upregulated cancer-promoting STAT3 in Ca-Ski cells. Additionally, these extracts inactivated the PI3K signalling pathway in HeLa cells but not in Ca-Ski cells. The resistance of the Ca-Ski cells to the D. calcarata extracts may be due to the upregulation of STAT3 and activated PI3K signalling pathway. The cytotoxicity and apoptosis induction in HeLa cells by D. calcarata extracts may be attributed to downregulation of STAT5A survival mechanisms. Water fractions 1, 2, 3 and 6 and methanol fractions 1 and 2 reduced cell viability of HeLa cells. Water fractions 2, 3 and 6 and methanol fractions 1 and 3 induced apoptosis, which was preceded by secondary necrosis. However, water fraction 1 and methanol fraction 2 led to most cells undergoing necrotic cell death. There are several compounds that can be credited with the anticancer activities of the ME and WE extracts since several fractions exhibited cytotoxicity against the HeLa cells.

Conclusion

These findings suggest that the D. calcarata extracts have anticancer activities, and thus, could be useful for therapeutic purposes against human HPV-18 positive gynaecologic cancers.

背景牛蒡子提取物对人宫颈癌的治疗作用尚不清楚。目的研究鹿茸球茎提取物对宫颈癌细胞的细胞毒作用。方法采用MTT法、Ki67法和PI3K活化法检测牛角菜提取物的生长抑制作用。采用荧光显微镜、MuseⓇ细胞分析仪和RT-PCR检测细胞凋亡诱导情况。MTT法测定各组细胞毒性,MuseⓇ细胞分析仪测定各组细胞凋亡诱导率。结果甲醇提取物(ME)和水提取物(WE)对KMST-6和HEK-293细胞均具有安全性。提取物具有抗HeLa的活性,对Ca-Ski细胞无明显的细胞毒作用。WE使Ki67阳性Ca-Ski细胞数量增加,而ME和WE均在G2/M期阻滞HeLa细胞,在G0/G1期阻滞Ca-Ski细胞。AO/EB染色、Annexin V和Caspase 3/7活化显示,提取物显著诱导HeLa细胞凋亡。在HeLa细胞中,ME下调了TP53变体,而WE上调了HeLa细胞中的两种TP53变体。两种提取物均可降低HeLa细胞中STAT5A和STAT5B mRNA的表达;然而,这些提取物上调Ca-Ski细胞中促癌的STAT3。此外,这些提取物在HeLa细胞中灭活PI3K信号通路,而在Ca-Ski细胞中不灭活。Ca-Ski细胞对calcarata提取物的抗性可能是由于STAT3的上调和PI3K信号通路的激活。马六甲提取物对HeLa细胞的细胞毒性和诱导凋亡作用可能与下调STAT5A存活机制有关。水馏分1、2、3、6和甲醇馏分1、2降低HeLa细胞的活力。水馏分2、3、6和甲醇馏分1、3诱导细胞凋亡,在此之前发生继发性坏死。然而,水馏分1和甲醇馏分2导致大多数细胞发生坏死细胞死亡。有几种化合物可以被认为是ME和WE提取物的抗癌活性,因为一些部分对HeLa细胞表现出细胞毒性。结论牛角菜提取物具有抗肿瘤活性,可用于治疗人HPV-18阳性妇科肿瘤。

Background

Skin and soft tissue infections are frequent. Candidiasis and Aspergillosis are the most common cutaneous fungal infections. Yemeni alum (Aluminium Potassium Sulphate) is a natural mineral with antifungal and antibacterial properties.

Objective

This study aimed to confirm Yemeni alum's antifungal effectiveness against selected fungal strains and develop useful topical formulations.

Methods

Using different alum concentrations, we prepared twenty-three formulations, including four non-adjusted aqueous solutions, eight adjusted pH aqueous solutions, eight glycerite solutions, and three Oil/Water cream formulations. Then, we examined the antifungal activity against the suggested fungus. The animal skin irritation test evaluated the local skin sensitivity reactions that might happen upon using the formulations we prepared on the intact animal's skin. Additionally, this study also included six weeks of stability testing to estimate the expected shelf life (t90) of the selected formulations.

Results

Alum exerted antifungal effect against Candida albicans, Aspergillus niger, and Aspergillus flavus. The animal's skin was not irritated by any of the formulations examined. The 5% alum aqueous solution and the 10% alum Oil/Water cream exhibited promising results among all tested formulations. The approximate formulation's shelf-lives (t90) were 2 and 1.52 years with alum content (%) ranging between 105.75% to 106.02%, respectively.

Conclusion

Based on the results we found, 10% alum Oil/Water cream is a promising formulation for large-scale manufacture.

COVID-19 presents particularly severe respiratory and systemic infection in aging and immunosuppressed individuals, including patients with cancer.

Objective

In the present review, we focused on emergent evidence from cancer sufferers that have been contaminated with COVID-19 and cancer patients who were at higher risk of severe COVID-19, and indicates that anticancer treatment may either rise COVID-19 susceptibility or have a duple therapeutic impact on cancer as well as COVID-19; moreover, how SARS-CoV-2 infection impacts cancer cells. Also, to assess the global effect of the COVID-19 disease outbreak on cancer and its treatment.

Methods

A literature survey was conducted using PubMed, Web of Science (WOS), Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), and VIral Protein domain DataBase (VIP DB) between Dec 1, 2019 and Sep 23, 2021, for studies on anticancer treatments in patients with COVID-19. The characteristics of the patients, treatment types, mortality, and other additional outcomes were extracted and pooled for synthesis.

Results

This disease has a huge effect on sufferers who have cancer(s). Sufferers of COVID-19 have a greater percentage of tumor diagnoses than the rest of the population. Likewise, cancer and highest proportion is lung cancer sufferers are more susceptible to COVID-19 constriction than the rest of the population.

Conclusion

Sufferers who have both COVID-19 and tumor have a considerably elevated death risk than single COVID-19 positive patients overall. During the COVID-19 pandemic, there was a reduction in the screening of cancer and detection, and also deferral of routine therapies, which may contribute to an increase in cancer mortality there in future.

背景:在全球范围内,新冠肺炎疫情对卫生服务产生了重大影响,并导致卫生机构的日常护理中断,使癌症患者面临严重风险。在疫情封锁期间提供不间断的肿瘤治疗是一个主要障碍。冠状病毒疾病(新冠肺炎)及其致病病毒SARS-CoV-2对肿瘤患者的管理提出了相当大的挑战。新冠肺炎在包括癌症患者在内的老年和免疫抑制患者中表现出特别严重的呼吸道和全身感染。目的:在本综述中,我们重点关注受新冠肺炎污染的癌症患者和严重新冠肺炎风险较高的癌症患者的新证据,并表明抗癌治疗可能会增加新冠肺炎易感性,或对癌症和新冠肺炎产生双重治疗影响;此外,SARS-CoV-2感染如何影响癌症细胞。此外,评估新冠肺炎疫情对癌症及其治疗的全球影响。方法:在2019年12月1日至2021年9月23日期间,使用PubMed、Web of Science(WOS)、Embase、Cochrane图书馆、中国知识基础设施(CNKI)和VIral蛋白质结构域数据库(VIP DB)进行文献调查,以研究新冠肺炎患者的抗癌治疗。提取患者的特征、治疗类型、死亡率和其他额外结果,并合并进行综合。结果:这种疾病对癌症患者有巨大的影响。新冠肺炎患者的肿瘤诊断率高于其他人群。同样,癌症和比例最高的是癌症患者比其他人群更容易感染新冠肺炎。结论:与单个新冠肺炎阳性患者相比,同时患有新冠肺炎和肿瘤的患者的死亡风险显著升高。在新冠肺炎大流行期间,癌症的筛查和检测有所减少,常规治疗也有所推迟,这可能会导致未来癌症死亡率的上升。

Background

Ischemic stroke has been regarded as a major cause of disability and death around the world due to limited effective therapies. Accumulating evidence have shown that although microglia are polarized to an anti-inflammatory M2 phenotype in the early stage of ischemia, they transform progressively into a proinflammatory M1 phenotype. Bone marrow-derived mesenchymal stem cells (BMSCs) may be used to treat ischemic injury through regulating the poststroke inflammatory response. However, the mechanism by which BMSCs can treat ischemic stroke remains unclarified.

Objective

This study aimed to investigate whether BMSCs shift M1-to-M2 phenotype transformation of microglia/macrophages and enhance neurogenesis in a rat transient middle cerebral artery occlusion (tMCAO) model.

Methods

Ninety-minute tMCAO was applied to the rats, followed by reperfusion. BMSCs were transplanted into the rats via intravenous injection at 24 h after tMCAO. After being randomly divided into the sham group, the MCAO group, and the BMSCs group, the rats’ behavior was assessed at 1, 3, 7, and 14 days following tMCAO. qRT-PCR, double-immunofluorescence staining, and Western blot were performed at 3 and 14 days after tMCAO to determine M1/M2 polarization of microglia/macrophages. Neurogenesis was examined by double-immunofluorescence staining at 14 days after tMCAO. Expression of brain-derived neurotrophic factor (BDNF) was measured on the protein level by immunofluorescence staining at 3 and 14 days after tMCAO.

Results

We found that BMSCs treatment promoted the recovery of neurological function after tMCAO, inhibited the expression of TNFα, iNOS and CD16/32, which are markers of M1 microglia/macrophage, and enhanced the expression of IL10, TGFβ and CD206 that are markers of M2 microglia/macrophage. Moreover, BMSCs treatment promoted neurogenesis and M2-derived BDNF expression after tMCAO.

Conclusion

It is indicated by the results that BMSCs modulate neuroinflammation and enhance neurogenesis, which could be due to transforming microglia/macrophages from the M1 polarization state towards M2 in a rat tMCAO model.

在世界范围内,由于有效的治疗方法有限,非化学性中风一直被认为是导致残疾和死亡的主要原因。越来越多的证据表明,尽管小胶质细胞在缺血早期极化为抗炎M2表型,但它们逐渐转变为促炎M1表型。骨髓间充质干细胞(BMSCs)可能通过调节脑卒中后炎症反应来治疗缺血性损伤。然而,骨髓间充质干细胞治疗缺血性中风的机制尚不清楚。目的探讨骨髓间充质干细胞在大鼠短暂性大脑中动脉闭塞(tMCAO)模型中是否能改变小胶质细胞/巨噬细胞的m1 - m2表型转化并促进神经发生。方法给药90 min后再灌注。骨髓间充质干细胞于tMCAO后24 h静脉注射移植到大鼠体内。将大鼠随机分为假手术组、MCAO组和骨髓间充质干细胞组,分别于tMCAO后1、3、7、14天对大鼠行为进行评估。tMCAO后第3、14天采用qRT-PCR、双免疫荧光染色、Western blot检测小胶质细胞/巨噬细胞M1/M2极化情况。术后第14天采用双免疫荧光染色检测神经发生。采用免疫荧光染色法在蛋白水平上检测脑源性神经营养因子(BDNF)在tMCAO后3和14 d的表达。结果BMSCs治疗促进了tMCAO后神经功能的恢复,抑制了M1小胶质细胞/巨噬细胞标志物TNFα、iNOS和CD16/32的表达,增强了M2小胶质细胞/巨噬细胞标志物IL10、TGFβ和CD206的表达。此外,骨髓间充质干细胞治疗促进了tMCAO后神经发生和m2源性BDNF的表达。结论骨髓间充质干细胞调节神经炎症,促进神经发生,其机制可能是将大鼠tMCAO模型中的小胶质细胞/巨噬细胞由M1极化态向M2极化态转变。

It has been established that osteoarthritis (OA) refers to diseases with high comorbidity. According to available data, OA is most often combined with arterial hypertension (AH) and other cardiovascular diseases (CVD). The combination of OA and CVD causes certain difficulties when choosing drug therapy. Traditionally, with pain syndrome, the choice falls on NSAIDs, since this allows in most cases to get a quick response to treatment. However, the use of NSAIDs may be accompanied by an increase in average blood pressure by 5 mm Hg or more in patients with arterial hypertension (AH) and significantly reduces the antihypertensive effectiveness of beta-blockers and ACE inhibitors. Symptomatic effect of the use of symptom-modifying drugs of delayed action (SYSADOA - Symptomatic slow acting drugs for osteoarthritis) develops approximately 8-12 weeks after the start of administration. Limitations in the use of NSAIDs in patients with OA and CVD due to increased cardiovascular risk and a long waiting period for the onset of the effect when using drugs of the SYSADOA group dictate the need to search for new approaches in the treatment of OA, on the one hand, with rapid effectiveness, and on the other - meeting all the requirements of cardiovascular safety. It is known that local injection therapy with the use of different groups of drugs has high efficiency in OA: glucocorticosteroids (GCS), hyaluronic acid, chondroitin, etc. Currently, microinduction collagen preparations with a high safety profile have joined them. Special attention in OA deserves the drug Plexatron, which has in its composition a type 1 tropocollagen with a molecular weight of 300 kD and calcium phosphate 1 mcg, and is intended for intra-articular and periarticular administration. Injectable collagen preparations are capable of inducing the regeneration of damaged collagen fibers by stimulating the migration of fibroblasts to the sites of damage, the release of growth factors and the activation of a key enzyme for the induction of endogenous collagen synthesis - lysine hydroxylase
骨关节炎(OA)是指具有高合并症的疾病。根据现有资料,OA最常合并动脉高血压(AH)和其他心血管疾病(CVD)。OA和CVD合并在选择药物治疗时存在一定的困难。传统上,对于疼痛综合征,选择非甾体抗炎药,因为这在大多数情况下可以快速得到治疗反应。然而,在动脉性高血压(AH)患者中,使用非甾体抗炎药可能伴有平均血压升高5mmhg或更高,并显著降低β受体阻滞剂和ACE抑制剂的降压效果。使用延迟作用的症状缓解药物(SYSADOA -治疗骨关节炎的症状性缓慢作用药物)的症状效应在开始给药后大约8-12周出现。非甾体抗炎药在OA和CVD患者中使用的局限性在于,在使用SYSADOA组药物时,心血管风险增加,且效果起效的等待时间长,这要求我们需要寻找治疗OA的新方法,一方面要快速有效,另一方面要满足心血管安全性的所有要求。已知局部注射治疗不同药物组对OA疗效高:糖皮质激素(GCS)、透明质酸、软骨素等。目前,具有高安全性的微诱导胶原蛋白制剂已加入其中。对于骨性关节炎,值得特别关注的是Plexatron药物,其成分中含有分子量为300 kD的1型对胶原蛋白和1 mcg的磷酸钙,用于关节内和关节周给药。可注射的胶原制剂能够通过刺激成纤维细胞向损伤部位的迁移、生长因子的释放和诱导内源性胶原合成的关键酶赖氨酸羟化酶的激活来诱导受损胶原纤维的再生
