AIM: To investigate the correlation of hepatitis B virus X protein (HBx) with renal tubular epithelialcell apoptosis in hepatitis B virus-associated glomerulonephritis (HBVGN) and the possible signaling mechanism. METHODS: The activation of JAK2/STAT3 signal pathway and the expression of apoptosis -related proteins in humankindey proximal tubular epithelial cells (HK-2 cells) were determined by Western blotting after transfection with HBx eukaryoticexpression vector.The cell proliferation was observed by CCK-8 assay.The cell apoptosis was analyzed by the imagingof HO33342 staining, transmission electron microscopy and flow cytometry with Annexin V /PI double staining.RESULTS:After transfection of the target gene HBx, the expression levels of both p-JAK2 and p-STAT3 were significantly increased.At the same time, the cell proliferation was obviously inhibited, and the apoptotic rate was increased.After incubationwith AG490, the JAK2/STAT3 signal pathway was partially blocked, and the cell apoptosis induced by HBx was reduced. CONCLUSION: HBx up-regulates the activation of JAK2/STAT3 signal pathway to induce renal tubular epithelialcell apoptosis, which is possibly involved in the pathogenic mechanism that HBV directly damages nephridial tissue .

Objective To evaluate the accuracy of the patient positioning in prostate cancer therapy with the kilo-volt X-ray imaging system. Methods From June to August in 2014,14 patients with prostate cancer were treated by carbon ion beam with the Siemens proton and carbon ion equipment. X-ray orthogonal images was made twice by the imaging system before treatment. All the images were fused with the planning digitally reconstructed radiograph ones by automatic and manual method. We got positioning error data in six directions:lateral, longitudinal, vertical, isocentre, roll and pitch. The data were analyzed to study the situation. Results A total of 644 pairs of images from 14 patients were obtained during treatment. The average error in six directions is 0. 34 cm,0. 30 cm,0. 79 cm,0. 3°,1. 1° and 0. 5°.The patients′positioning error had no obvious change in all directions with fractions. There was no significant deviation between the two groups of images,either. But error in pitch and vertical direction is much larger. Conclusions The bony landmarks of the orthogonal filed images are clear. Photography lasts short time by the imaging system. DRR images are 3D and we can get images in six directions,but the development of soft tissue is weak. Positioning error we get cannot be match with the one of actual situation.

Objective To explore the effects of amlodipine,perindopril and valsartan on plasma adiponectin and retinol binding protein 4 in elderly patients with essential hypertension.Methods From March 2007 to July 2010,238 elderly patients with essential hypertension were selected and 193 cases completed this study.Patients were randomly divided into 3 groups:amlodipine group (n=68),perindoprilgroup (n=60) and valsartan group (n=65).Patients in each group were treated with amlodipine,perindopril and valsartan respectively for at least 12 weeks.The changes in blood pressure,heart rate,body height,body mass index (BMI),abdominal circumference,waist circumference (WC),levels of blood lipids,plasma adiponection and retinol binding protein 4 were observed before and after treatment.Results Compared with pre-treatment,systolic blood pressure in 3 groups were significantly decreased after treatment (all P＜0.01).There were no significant differences in blood pressure among 3 groups after treatment (all P＞0.05).Compared with pre treatment,plasma adiponectin level was significantly increased in perindopril group and valsartan group after treatment [(7.4±1.8) μg/L vs.(8.3± 1.8) μg/L,(7.5±1.7) μg/L vs.(8.4±1.9)μg/L,both P＜0.01].Plasma adiponectin level was higher in perindopril group and valsartan group than in amlodipine group after treatment [(8.3±1.8) μg/L vs.(7.6±1.8) μg/L,(8.4±1.9) μg/Lvs.(7.6±1.8) μg/L,both P＜0.05].Compared with pretreatment,plasma retinol binding protein 4 level in 3 groups were all decreased after treatment,and the decrements had significant differences in perindopril group and valsartan group (both P＜0.01) but had no difference in amlodipine group (P＞0.05).Plasma adiponectin retinol binding protein 4 levels were lower in perindopril group and valsartan group than in amlodipine group after treatment[(36.6± 14.2) μg/L vs.(42.7± 13.8) μg/L,(36.3±14.1) μg/L vs.(42.7±13.8) μg/L,respectively,both P＜0.01].Conclusions Perindopril and valsartan play important roles in cardiovascular protection beyond the antihypertensive effects by increasing plasma adiponection level and decreasing plasma retinol binding protein 4 level in elderly patients with hypertension.

This study is to investigate the therapeutic effect and mechanism of indole-3-carbinol (I3C) on pig serum-induced liver fibrosis of rats. The liver fibrotic model of rats was induced by pig serum. After models were successfully established, rats in the treatment groups were administered with I3C through intraperitoneal injection or curcumin by intragastric administration, daily for 17 days. Hepatic hydroxyproline (Hyp) content was measured. The liver histology and immunohistochemistry with a-smooth muscle actin (alpha-SMA) were assayed. Hepatic stellate cells line, HSC-T6 was incubated with different concentrations of I3C (25, 50, and 100 micromol x L(-1)) for 24 h. The effect of I3C on cell apoptosis was identified by FITC-Annexin V/PI double labeled assay. And the mRNA expressions of Bax and Bcl-2 were measured by real time RT-PCR. The results showed that hepatic content of Hyp decreased by I3C treatment, as compared with the fibrotic model control. Histopathological changes, such as steatosis, necrosis, deposition of collagenous fiber reduced remarkably and the expression of alpha-SMA was significantly down-regulated in the I3C-treated groups (P < 0.01). Apoptosis analysis showed that I3C significantly increased HSC-T6 apoptosis rate and the expressional ratio of Bax to Bcl-2. The results indicated that I3C could effectively cure pig serum-induced liver fibrosis in vivo by inducing HSC apoptosis and promoting ECM degradation.

Objective To retrospectively analyze the relationship of the classification and risk stratification in senile hypertension with benign prostatic byperplasia (BPH).Methods Totally 376 male senior patients,including 233 senile hypertensive patients and 143 non-hypertensive patients as a control,were enrolled in this study.There were 35 cases of hypertension at level 1,82 cases at level 2,116 cases at level 3.Based on risk stratification of hypertension,there were 3 cases of low-risk,28 cases of medium risk,75 cases of high-risk,127 cases of very high risk.All candidates accepted the International Prostatic Symptom Score (IPSS) assessment before the treatment.Fasting blood glucose (FBG),total cholesterol (TC),triglycerides (TG),low density lipoprotein cholesterol (LDL-C),high density lipoprotein cholesterol (HDL-C) and prostate specific antigen (PSA) were determined.Body mass index (BMI) and prostate volume (PV) were calculated.Relationship of classification and risk stratification in hypertension with BPH were analyzed.Results The levels of systolic blood pressurc (SBP),diastolic blood pressure (DBP),body weight,BMI,FBG and TC were higher (t=3.883,2.498,2.161,3.399,2.200,2.370,P＜0.05 or P＜0.01),while serum HDL-C were lower (t=2.036,P＜0.05) in hypertensive patients than in control group.Compared with the control group,IPSS and PV was increased (t =3.432,3.381,both P＜0.01) in hypertension group.Risk rate of hypertensive patients with BPH was 2.03 times (95％CI:1.33-3.11,P＜0.01) as compared with control group.In hypertensive patients,PV and IPSS were higher in level 2 or 3 grade group than in level 1 group (F=6.890,7.576,all P＜0.01).PV and IPSS in high risk and very high risk groups were enhanced as compared with those in low-medium risk group (F=30.608,19.804,all P＜0.01).Pearson analysis showed that PV was positively correlated with SBP,FBG and TC(r=0.223,0.251,0.305,all P＜0.05),while negatively correlated with HDL-C(r =-0.235,P＜0.05).Similarly,IPSS was positively correlated with SBP,DBP and FBG (r=0.396,0.273,0.224,all P＜0.01),while negatively correlated with HDL-C (r =-0.288,P＜ 0.01).Conclusions High incidence of BPH appears in the elderly men with hypertension.The increased PV and IPSS coexist with conventional risk factors of essential hypertension.Development of BPH is closely related to higher blood pressure and risk stratifications of hypertension.
