Penetration moxibustion for postpartum subinvolution of uterus: Two case reports and mechanism analysis: 透灸法成功治疗产后子宫复旧不良:两则病例报告及机制分析

This article introduced the application of penetration moxibustion in successfully treating two cases of postpartum subinvolution of uterus. The main complaint of one case was increasing volume of abnormal vaginal bleeding for five days after delivery. The bleeding stopped after the patient received 7 times treatment of warming needle and penetration moxibustion on Zhōngjí (中极CV3), Guānyuán (关元CV4) and Qìhăi (气海CV6). The other case complained about persistent abdominal pain for 15 days, which was worsening for the recent 2 days. The symptom of abdominal pain was relieved after the penetration moxibustion was applied on CV4, CV6 and Zǐgōng (子宫 EX-CA1) for 5 times for the case. Penetration moxibustion can relieve abdominal pain during the postpartum period, accelerate lochia discharge, and recovery of menstrual and uterine cavity. Àiyè (艾叶 Artemisiae Argyi Folium) was proved to have antibacterial, hemostatic, and analgesic effects. The warming function and radiation features of moxibustion can help to alleviate spasm of the smooth muscle in the uterus and enhance the metabolism of the uterine tissue by expanding microvessels and improving the circulations of both blood and lymph. It can also activate cells in the uterine tissue by increased temperature in order to enhance the decomposition and elimination of pathological wastes, such as inflammation and hematoma. In addition, it can also relieve pelvic pain by inhibiting neuronal excitability.     

胆总管结石治疗后复发因素的研究进展

胆总管结石是外科最常见的良性疾病之一,随着科技的进步、医疗技术的提升以及医院硬件设施的完善,经内镜逆行性胰胆管造影术（ERCP）及腹腔镜胆总管探查术（LCBDE）已经成为胆总管结石的主要治疗手段,且具创伤小、恢复快的临床优势。但是,临床多中心研究数据显示,胆总管结石术后复发率为4%~24%,因此,胆总管结石术后复发是外科医生必须面对的挑战和亟待解决的问题。胆总管结石的形成是一个复杂的遗传和环境因素相互作用的过程,其具体机制尚未完全阐明,术后复发机制及相关因素亦成为临床研究的难点和热点。笔者通过整理归纳相关文献,从十二指肠乳头括约肌功能、胆道微生态、胆道解剖三个维度,阐述胆总管结石术后复发的相关机制与研究进展,为预防胆总管结石术后复发提供新的策略和研究方向。

Protein regulator of cytokinesis 1 overexpression predicts biochemical recurrence in men with prostate cancer

BackgroundProtein regulator of cytokinesis 1 (PRC1) has been reported to be implicated into the completion of cytokinesis and is dys-regulated in a cancer-specific manner. However, it roles in human prostate cancer (PCa) remain unclear. In the current study, we aimed to investigate the expression pattern of PRC1 and its clinical significance in this malignancy.Materials and methodsPRC1 protein expression in human PCa and non-cancerous prostate tissues was detected by immunohistochemistry, which was validated by microarray-based Taylor data at mRNA level. Then, the associations of PRC1 expression with clinicopathological features and clinical outcome of PCa patients were statistically analyzed.ResultsPRC1 expression in PCa tissues, at both mRNA and protein levels, were significantly higher than those in non-cancerous prostate tissues. In addition, the PCa patients with PRC1 overexpression more frequently had high Gleason score, advanced pathological stage, positive metastasis, short overall survival time and positive PSA failure than those with low Gleason score, early pathological stage, negative metastasis, long overall survival time and negative PSA failure (all P < 0.05). Moreover, PRC1 expression was identified as an unfavorable prognostic factor of biochemical recurrence-free survival in PCa patients (P < 0.001).ConclusionThese findings suggest that the aberrant expression of PRC1 may predict biochemical recurrence in men with PCa highlighting its potential as a prognostic marker of this malignancy.

Expression pattern of NMDA receptors reveals antiepileptic potential of apigenin 8-C-glucoside and chlorogenic acid in pilocarpine induced epileptic mice

The present study was aimed to evaluate the effect of apigenin 8-C-glucoside (Vitexin) and chlorogenic acid on epileptic mice induced by pilocarpine and explored its possible mechanisms. Intraperitonial administration of pilocarpine (85 mg/kg) induced seizure in mice was assessed by behavior observations, which is significantly (p > 0.05) reduced by apigenin 8-C-glucoside (AP8CG) (10 mg/kg) and chlorogenic acid (CA) (5 mg/kg), similar to diazepam. Seizure was accompanied by an imbalance in the levels of Gamma-aminobutyric acid (GABA) and glutamate in the pilocarpine administered group. Moreover, convulsion along with reduced acetylcholinesterase, increased monoamine oxidase and oxidative stress was observed in epileptic mice brain. AP8CG and CA significantly restored back to normal levels even at lower doses. Further, increased lipid peroxidation and nitrite content was also significantly attenuated by AP8CG and CA. However, CA was found to be more effective when compared to AP8CG. In addition, the mRNA expression of N-methyl-d-aspartate receptor (NMDAR), mGluR1 and mGlu5 was significantly (P ≤ 0.05) inhibited by AP8CG and CA in a lower dose. The mRNA expression of GRIK1 did not differ significantly in any of the group and showed a similar pattern of expression. Our result shows that AP8CG and CA selectively inhibit NMDAR, mGluR1 and mGlu5 expression. Modification in the provoked NMDAR calcium response coupled with neuronal death. Hence, these findings underline that the polyphenolics, AP8CG and CA have exerted antiepileptic and neuroprotective activity by suppressing glutamate receptors.     

Efficacy and safety of HER2-targeted therapy in patients with colorectal cancer: What should we expect from a meta-analysis?

Background and objectiveHuman epidermal growth factor receptor 2 (HER2) is an effective therapeutic target for breast and stomach cancers. However, the application of HER2-targeted therapy in colorectal cancer (CRC) remains controversial. We sought to assess the efficacy and safety of HER2-targeted therapy in CRC by performing a meta-analysis of relevant studies.MethodsWe searched PubMed, Embase, Cochrane Library, Web of Science, and the ClinicalTrials.gov database to retrieve relevant studies. STATA 16 was used for the statistical analysis. The objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), and incidence of treatment?related adverse events (TRAEs) were used as the outcome indicators analyzed by random- or fixed-effects models.ResultsA total of 267 patients from nine studies were included in this meta-analysis. The overall ORR and DCR were 27.5% (95% CI 16.8% to 39.6%) and 68.9% (95% CI 55.4% to 81.0%), respectively. No significant heterogeneity was found in PFS among these studies and the overall median PFS was 4.35 months (95% CI 3.70 to 4.99). The overall incidence of all-grade and grade 3 or higher adverse events were 93.5% (95% CI 88.4% to 97.4%) and 16.8% (95% CI 4.8% to 33.3%).ConclusionsHER2-targeted therapy was confirmed as a promising treatment for colorectal cancer, warranting further high-quality clinical randomized controlled trials to verify.
