Meta analysis of whether cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy can improve survival in patients with colorectal cancer peritoneal metastasis / 中华胃肠外科杂志

Objective: To explore whether the cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (CRS+HIPEC) can improve the survival rate of colorectal cancer patients with peritoneal metastasis. Methods: The relevant studies were systematically retrieved from PubMed, Embase, Cochrane Library, CNKI, Wanfang, VIP database, and the study of French Elias' team on peritoneal metastasis was retrieved manually. Inclusion criteria: (1) The patients were colorectal cancer peritoneal metastasis. (2) There were CRS+HIPEC treatments (treatment group) and other treatments (control group). (3) Survival analysis data of treatment group and control group were available. (4) Types of studies were randomized controlled trials, cohort studies, or case-control studies. (5) The literature was in Chinese or English. Exclusion criteria: (1) studies without full-text; (2) studies without complete data. The literature screening and data extraction were carried out by two people independently, and the third person decided on the literature with differences. The extracted data included authors, year of publication, number of patients, time of enrollment, time of follow-up, studies design, treatment regimen, hazard ratio (HR) and 95% CI of treatment group and control groups. If the HR and 95% CI of the treatment group and control group were not provided in the literature, Engauge Digitizer 11.1 software was used to extract the time of follow-up and the survival rate at the corresponding time point from the survival curves of both groups, and the HR and 95% CI of both groups were calculated by combining the number of both groups. The quality of study was evaluated by Newcastle-Ottawa scale (NOS) or Cochrane collaboration's tool for assessing risk bias. STATA 15.1 software was used for statistical analysis. HR and 95% CI of both groups were pooled and analyzed. Inter-trial heterogeneity was assessed by Q test and I(2) statistics. When there was no significant heterogeneity (Q test: P≥0.10), fixed-effect model was used for pooled analysis. When significant heterogeneity existed (Q test: P<0.10), random effect model was used for pooled analysis, and subgroup analysis was used to find out the source of heterogeneity. Sensitivity analysis was used to evaluate the stability of the pooled results. Publication bias was assessed by Egger's test and Begg's test (P<0.05 indicated publication bias) and it is reflected by the visual symmetry of Begg's funnel plot on the natural logarithm of HR. Results: A total of 10 studies were enrolled in the meta-analysis, including 1 randomized controlled trial and 9 cohort studies. The risk of bias in 1 randomized controlled trial was uncertain, and 9 cohort studies were all higher than 7 points, indicating high quality literatures. There were 781 patients in treatment group receiving CRS+HIPEC and 2452 patients in control group receiving other treatment, including tumor cytoreductive surgery (CRS), palliative chemotherapy (PC) and intraperitoneal chemotherapy (IPC). The results of pooled analysis by random effect model showed that the OS rate in treatment group was significantly higher than that in control group (HR=0.43, 95% CI: 0.34-0.54), but the heterogeneity of the study was high (P=0.024, I(2)=52.9%). The subgroup analysis of different control treatments showed that the OS rate in treatment group was significantly higher than that in CRS control group (HR=0.63, 95% CI: 0.44-0.90), in PC control group (HR=0.37, 95% CI: 0.32-0.43), in CRS+ IPC control group (HR=0.60, 95% CI: 0.37-0.96), and the heterogeneity of each subgroup was low (CRS control group: P=0.255, I(2)=22.9%; PC control group: P=0.222, I(2)=29.9%; CRS+IPC control group: P=0.947, I(2)=0). Due to the low heterogeneity of subgroups, fixed-effect models were used to pool and analysis. The results of sensitivity analysis revealed that there was little difference between the pooled analysis results after each study was deleted, suggesting that the pooled analysis results were more reliable. Publication bias detection of each study showed Begg's test (P=0.088) >0.05 and Egger's test (P=0.138)>0.05. According to the Begg's funnel plot, the scatter point distribution was basically symmetric, indicating that there was no publication bias in the included study. Conclusion: CRS+HIPEC can improve the OS of patients with colorectal cancer peritoneal metastasis.

Assessment and prediction of the oversea imported risk of COVID-19 in Shanghai / 上海预防医学

Objective To determine the association between global epidemic of COVID-19 and local situation of imported cases from abroad to Shanghai, and then to predict the risk of imported COVID-19 epidemic from December 2020 through March 2021. Methods A retrospective analysis on the imported COVID-19 cases from abroad to Shanghai was conducted. The correlation between global and country-specific confirmed COVID-19 cases(weekly confirmed cases per 100 000 population)and imported cases(weekly reported)in Shanghai was determined. Compared to the risk in November 2020, country-specific risk of imported cases to Shanghai was assessed to calculate the possible number of imported case in the near future using SEIR model. Results The number of imported case of COVID-19 from abroad to Shanghai increased along with the global epidemic, with several peaks accordingly. However, the imported cases did not accumulate, as potential epidemic has been always effectively contained through timely implementation of prevention and control measures. The number of weekly imported cases in Shanghai was significantly correlated with the number of global weekly confirmed cases per 100 000 population(rSpearman = 0.349, P = 0.029), and also correlated with weekly reported cases in certain countries(P < 0.05), such as the UK and France. Using the number of imported cases from abroad to Shanghai in November as baseline, the estimated monthly number of imported cases in Shanghai might increase in the following four months. Conclusion The risk of imported COVID-19 cases from abroad to Shanghai may increase in the near future. Prediction of imported case would provide scientific evidence for optimizing prevention and control measures and reserving medical resources for the imported epidemic.

Effects of glucagon-like peptide-1 analogue liraglutide on autophagy of human umbilical vein endothelial cells in high glucose conditions / 解放军医学杂志

Objective To explore the effect of glucagon-like peptide-1 (GLP-1) analogue liraglutide (LIRA) on autophagy of human umbilical vein endothelial cells (HUVECs) under high glucose condition, and its corresponding mechanism. Methods (1) The HUVECs were cultured in vitro and assigned to control group (group A) and high glucose group (group B). Group A and B were cultured respectively in 5.5mmol/L and 25mmol/L glucose medium for 12, 24 and 48 hours. The expressions of autophagy-related genes (beclin-1, LC3 and p62 mRNA) were determined by RT-PCR, and then the optimal culture time of high glucose condition on autophagy was selected. (2) The high glucose group at the optimal culture time point was treated with low, medium and high dose (10, 50, 100nmol/L) of LIRA (C1, C2, C3 groups). The same method was used to detect the indicators above, and the optimal intervention concentrations of LIRA were obtained. (3) In addition to the treatment of LIRA at optimal dose under high glucose condition (group C) and high glucose culture alone (group B), the AMPK inhibitor ComC (10μmol/L) was introduced (group D and group E). The fluorescence spots of green fluorescent protein (GFP) conjugated LC3 (GFP-LC3) were observed by laser confocal fluorescence microscopy to monitor the formation of autophagosome. The expressions of cell autophagy marker beclin-1, p62 and the ratio change of LC3-Ⅱ/LC3-, p-AMPK/AMPK and p-mTOR/mTOR were measured by Western blotting. Results (1) Compared with group A, the expressions of beclin-1 and LC3 mRNA in group B decreased, while of p62 mRNA increased at different culture time (P0.05). Compared with group D, LC3-Ⅱ/LC3- ratio decreased and the expression of p62 protein increased in group E (P<0.05). The change trend of autophagy fluorescent spots GFP-LC3 was consistent with that of autophagy related protein. Conclusion GLP-1 analogue liraglutide may protect HUVECs from high glucose condition by activating autophagy, which was achieved through AMPK-mediated signaling pathway.

Role of axl in preeclamptic EPCs functions / 华中科技大学学报（医学）（英德文版）

Axl encodes the tyrosine-protein kinase receptor, participating in the proliferation and migration of many cells. This study examined the role of Axl in functions of endothelial progenitor cells (EPCs). Axl was detected by RT-PCR and Western blotting in both placentas and EPCs from normal pregnancy and preeclampsia patients. The Axl inhibitor, BMS777-607, was used to inhibit the Axl signalling pathway in EPCs. Cell proliferation, differentiation, migration and adhesion were measured by CCK-8 assay, cell differentiation assay, Transwell assay, and cell adhesion assay, respectively. Results showed the expression levels of Axl mRNA and protein were significantly higher in both placentas and EPCs from preeclampsia patients than from normal pregnancy (P<0.05). After treatment with BMS777-607, proliferation, differentiation, migration and adhesion capability of EPCs were all significantly decreased. Our study suggests Axl may play a role in the function of EPCs, thereby involving in the pathogenesis of preeclampsia.

Effect of cholic acid on fetal cardiac myocytes in intrahepatic choliestasis of pregnancy / 华中科技大学学报（医学）（英德文版）

This study examined the effect of cholic acid (CA) on cultured cardiac myocytes (CMs) from neonatal rats with an attempt to explore the possible mechanism of sudden fetal death in intrahepatic cholestasis of pregnancy (ICP). Inverted microscopy was performed to detect the impact of CA on the beating rates of rat CMs. MTT method was used to study the effect of CA on the viability of CMs. CMs cultured in vitro were incubated with 10 μmol/L Ca(2+)-sensitive fluorescence indicator fluo-3/AM. The fluorescence signals of free calcium induced by CA were measured under a laser scanning confocal microscope. The results showed that CA decreased the beating rates of the CMs in a dose-dependent manner. CA could suppress the activities of CMs in a time- and dose-dependent manner. CA increased the concentration of intracellular free calcium in a dose-dependent manner. Our study suggested that CA could inhibit the activity of CMs by causing calcium overload, thereby leading to the sudden fetal death in ICP.

<p><b>OBJECTIVE</b>To establish a method to test citrinin (CIT) in monascus products by immuno-affinity chromatography (IAC)-high performance liquid chromatography (HPLC), and to detect the content of CIT in monascus products in Fujian province.</p><p><b>METHODS</b>IAC-HPLC was applied to detect the CIT content in monascus products. The conditions to use HPLC were as follows: C(18) reversed-phase chromatographic column, 150.0 mm×4.6mm×3 µm; mobile phase: the volume ratio of acetonitrile and 0.1% phosphoric acid solution at 65:35; isocratic elution; column temperature: 28°C; flow velocity: 0.8 ml/min; fluorescence detector, excitation wavelength (λ(ex)) was 331 nm and emission wavelength (λ(em)) was 500 nm. The standard curved was established by the linear regression of peak area (Y) to CIT content (X, ng/ml). The accuracy and precision of the method would then be verified. And 32 kinds of monascus products were determined and their color values were compared by this method.</p><p><b>RESULT</b>The standard curve established in this study was Y = 4634.8X-136.42, r = 1.000; whose limits of detection was 20 µg/kg and the limits of qualification was 64 µg/kg. In the range between 200 and 800 µg/kg, the standard recovery rate was 98.9% - 110.0% (n = 3), and the relative standard deviation (RSD) was 0.51% - 1.76%. Out of the 32 samples, CIT was detected from 11 samples of monascus rice, 9 samples of monascus powder and 5 samples of monascus pigments, the content was around 0.212 - 14.500 mg/kg. 4 out of 7 functional monascus samples were detected out CIT, whose content at 0.142 - 0.275 mg/kg.</p><p><b>CONCLUSION</b>The method to detect CIT in monascus products by IAC-HPLC has been established.</p>

Evaluation of GE7-transferring system-mediated HSV(1)-tk gene transfer in a rat model of ovarian tumor via intra-arterial route / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To observe the gene and protein expression of herpes simplex virus type I-thymidine kinase (HSV(1)-tk) in the ovarian tumor tissues and other organs after arterial infusion of HSV(1)-tk gene mediated by GE7 delivery system.</p><p><b>METHODS</b>GE7-polylysine/pCMV-HSV(1)-tk/polylysine-HA20 complexes were constructed. Nine rats with induced ovarian tumor were divided into 3 groups, injecting the 4-element complexes or saline buffer through the ovarian artery and complexes through the tail vein, respectively. The ovarian tumors, hearts, livers, spleens, lungs and kidneys were obtained at 72 hours after injection. RT-PCR and Western Blot were preceeded to determine the expression of HSV(1)-tk gene and protein in the tumor tissues and other organs.</p><p><b>RESULTS</b>In the group of arterial injection with 4-element complexes, the HSV(1)-tk gene and protein were expressed strongly in the tumor tissues, while little or none was detected in other organs. In the group of arterial injection with saline buffer, no HSV(1)-tk gene and protein was detected in both tumor tissues and other organs. In the group of tail vein injection, none was detected in tumor tissues and only little was found in the livers, spleens, lungs and kidneys.</p><p><b>CONCLUSION</b>High target and gene transfer rates can be obtained when HSV(1)-tk gene is transferred via the artery route mediated by GE7 delivery system. HSV(1)-tk protein can be expressed after the gene transfer. The results may provide a new strategy for target killing of HSV(1)-tk/GCV system in ovarian tumors.</p>
