Effects of salviae miltiorrhizae (SM) and SOD on serum and tissue (liver, intestine) lipid peroxidation were studied on rabbits in reperfusion after hemor rhage shock.The results showed that both SM and SOD could effectively reduce the serum MDA,while the inhibitory effect of SM on tissue (intestine) lipid Peroxidation was more significant than that of SOD.90 min after shock,18 rabbits were equally divided into 3 groups,one third of shed blood was re-infused and simultaneously teperfused with balanced salt solution (BSS) (group A), SOD in BSS (group B) and SM in BSS (group C). After reperfusion, serum MDA increased significantly in group A, while serum in MDA in group B and C decreased gradually and was significantly lower than that of group A after reperfusion of 3 hr (I3). Intestine MDA in group C was evidently lower than that in group A (P

Objective To investigate the effect of Zingiber corallinum oil ( ZCO ) on apoptosis and proliferation of cervical carcinoma cell line HeLa. Methods HeLa cells were treated with different concentrations of ZCO(5-80 mg·L-1)in vitro. Cytotoxicity rate was determined by CCK-8 assay. The morphological changes was observed using inverted microscope after AO/EB staining. Caspase-3 activities were measured with a colorimetric method. Protein level of hsp-70 were detected by Western blotting. Cell cycle and apoptosis were analyzed by flow cytometer ( FCM ) . Results ZCO exhibited effect of proliferation inhibition and apoptosis-inducing on the growth of HeLa cells in a dose-dependent manner. Caspase-3 activities increased in a dose-dependent manner while the expression of hsp-70 decreased. Cell cycle was arrested in G2/M phase. Conclusion ZCO exhibites a marked effect of proliferation inhibition and apoptosis-inducing on HeLa cells. The mechanism of ZCO might be activating the key enzyme in apoptotic pathway, so that the expression of hsp-70 is down-regulated, and cell cycle is arrested in G2/M phase.

Objective To investigate the associations between the single nucleotide polymorphisms of TERT rs2736098, CLK3 rs11543198 and bladder cancer. Methods 201 bladder cancer cases and 200 healthy controls were included in the research, and the genotypes of TERT rs2736098 and CLK3 rs11543198 were determined using the PCR-RFLP method. Relationship between genotypes and bladder cancer risks was investigated. Results There were statistical significance in the rs2736098 genotype frequencies and allele frequencies between cases and controls (χ2= 6.973, P = 0.031; χ2= 7.412, P = 0.006). Compared with the individuals with the GG genotype , the risk of bladder cancer increased 2.069 times with the AA genotype (OR = 2.069, 95%CI: 1.181-3.624, P = 0.011). And there were no significant associations between the rs11543198 genotype frequencies and allele frequencies between cases and controls (χ2 = 0.202, P = 0.904; χ2 = 0.188, P = 0.665). Rs2736098 and rs11543198 genotype distribution in bladder cancer pathologic grade and stage had no statistical significance (P > 0.05). Conclusion Rs2736098 polymorphism is associated with risk of bladder cancer and rs11543198 polymorphism was not associated with risk of bladder cancer.

Objective To investigate the expression of miR-520d-3p in 2 and 4 Gy X-ray irradiated A549 cells, serum samples of non-small cell lung cancer (NSCLC) patients and its significance. Methods Real time quantitative PCR (RT-qPCR) was employed to detect the expression miR-520d-3p in 2 and 4 Gy X-ray irradiated A549 cells in vitro. Besides, 0, 2 and 4 Gy X-ray irradiated A549 cells were used to prepare animal model of nude mice lung metastasis through mainline. The expressions of miR-520d-3p and lung tissue of nude mice were detected, and the serum samples of NSCLC patients were collected to test the expression of miR-520d-3p . Results Compared with the control group ( 0 Gy ) , the expression of miR-520d-3p was up-regulated significantly in 2 and 4 Gy X-ray irradiated A549 cells after 48 hours (1.00±0.03, 1.47±0.10, 1.84 ±0.09 respectively), and there was a significant difference (F= 94.350, P= 0.000). Furthermore, compared the control group with injection after 10 weeks, the expressions of miR-520d-3p in nude mice lung tissue in 0, 2 and 4 Gy X-ray irradiated groups were increased (2.33 ±0.13, 8.24 ±0.25, 3.46 ±0.14, respectively) (F=1.787, P= 0.227), and the expressions in serum were increased (11.43±2.30, 10.22±4.62, 8.99 ±3.67, respectively) (F= 1.547, P= 0.246). Out of 20 serum samples of NSCLC patients (including 10 cases of adenocarcinoma, 10 cases of squamous carcinoma ), 11 cases (55%) were detected with up-regulated miR-520d-3p expression. Conclusions 2 and 4 Gy X-ray could increase the expression of miR-520d-3p of A549 cells in vitro and in vivo, which might be correlated with the enhanced invasion and metastasis of A549 cells induced by X-ray in vitro and in vivo. Furthermore, the expressions of miR-520d-3p were increased significantly in over 50%serum samples of NSCLC patients, which might be a new marker for the diagnosis of NSCLC.

Objectives To investigate the effect of proliferation and invasiveness by turmeri cvolatile oil on human neuroblastoma cell line SH-SY5Y. Methods Cells were incubated with different concentrations of TVO in vitro. Then cell survival rate was measured by MTT assay. The effect of 160 mg/L TVO on cell migration was assessed by cell scuffing test. Invasive ability of cell was detected by Transwell test. Apoptosis of cells was detected observed by flow cytometry assay. Results Survival rate of SH-SY5Y cells decreased and apoptisis rate was abated with elevated TVO concentration and prolonged cultivation time. Level of cell migration was lower than that in control group after being cultured with 160 mg/L TVO solution for 12 , 24 and 48h. With the in-crease of TVO concentration , the invasion ability of cells gradually decreased , and the invasive force and cis-platin had no obvious difference when the concentration of drug reached 160 mg/L. Conclusion The prolifera-tion of cells can be inhibited by inhibiting the proliferation and invasiveness ability with TVO.

Objective:To evaluate the influencing factors of carotid-femoral pulse wave velocity (CF-PWV) and its value to predict outcomes in peritoneal dialysis (PD) patients.Methods:Eligible patients undergoing PD in Renji Hospital of Shanghai Jiao Tong University between August 2016 and July 2018 were recruited and prospectively followed up until death, PD cessation, or to the end of the study. CF-PWV was measured by an arterial pulse wave velocity meter to assess arterial stiffness (July 31, 2020). Overhydration was measured by bioimpedance spectroscopy. The patients were divided into CF-PWV≤10 m/s group and CF-PWV>10 m/s group according to the measured value of CF-PWV. The influencing factors of elevated CF-PWV were analyzed by multivariate logistic regression. Survival curves were generated using the Kaplan-Meier method and multivariate Cox proportional hazards models were used to analyze the difference for all-cause mortality and cardiovascular disease (CVD) mortality between the two groups.Results:A total of 224 PD patients were enrolled, including 133 males (59.4%). The age was (55.2±13.4) years old, and median PD vintage was 22.3(6.5, 59.3) months. Among them, 47(21.0%) patients were comorbid with diabetes, and 37(16.5%) patients had CVD history. The median CF-PWV was 9.6(8.4, 11.4) m/s for the cohort, and 105(46.9%) participants had CF-PWV over 10 m/s. Compared with CF-PWV≤10 m/s group, CF-PWV>10 m/s group patients had older age, increased percentage of diabetes and CVD (all P<0.05). Multivariate logistic analysis showed that increased age ( OR=1.070, 95% CI 1.043-1.099, P<0.001), diabetes ( OR=3.693, 95% CI 1.646-8.287, P=0.002) and higher overhydration ( OR=1.238, 95% CI 1.034-1.483, P=0.020) were independent influencing factors for elevated CF-PWV in PD patients. After followed up for 37.4(25.6, 41.7) months, 24 patients died, including 19 cases of CVD-related deaths. Kaplan-Meier survival analysis showed that all-cause mortality and CVD mortality were significantly higher in the CF-PWV>10 m/s group than those in CF-PWV≤10 m/s group (Log-rank χ2=6.423, P=0.011; Log-rank χ2=6.243, P=0.012, respectively). Multivariate Cox proportional hazards models showed that increased age was an independent influencing factor for both all-cause mortality and CVD mortality ( HR=1.057, 95% CI 1.010-1.107, P=0.018; HR=1.062, 95% CI 1.009-1.118, P=0.022). Conclusions:Increased arterial stiffness is relatively common in PD patients. Higher CF-PWV in PD patients is associated with increased age, diabetes and higher overhydration, and it is probably a valuable predictor of outcome in PD patients.

Objective: To improve physical activity by assessing pedometer-based physical activity during specific intervals over a week, among junior high school students,and to provide a reference for improving the level of students’ physical activity. Methods: Students (n=675) of grades 6-8 from six public junior high schools in Shanghai were recruited and instructed to wear a pedometer for a week, step counts and contents were recorded over a specific period. This period mainly included steps taken on the way to and from school, at school, at home in the evening on weekdays, and in the morning, afternoon, and evening on weekends. Results: The daily step counts recorded were 8 332 steps, with those on weekdays showing significantly higher values than step counts on weekends (9 065 steps vs. 6 392 steps)(t=22.9, P<0.01). Proportionately, the physical activity level at school contributed more to daily step counts (61.3%), followed by those on the commute to and from school(25.5%). Boys were more active than girls. For all intervals on weekdays, the step counts of students in rural districts, with overweight or obese, in grades 6 and 7, were higher than those in urban districts, with normal status, in grade 8 respectively (P<0.05). Low-activity students with physical education were more active than one without physical education(t boy=1.99,t girl=2.45,P<0.05). Conclusion These findings facilitate the implementation of effective, feasible interventions to enhance physical activity over a series of intervals during the day.
