OBJECTIVE: To observe the clinical efficacy of Shenyan kangfu tablet combined with benazepril in the treatment of chronic nephritis. METHODS: 160 chronic nephritis patients with healthy renal function were randomly divided into benazepril (ACEI) group and Shenyan kangfu tablet combined with benazepril group (combination group). 24 hour urinary protein, blood pressure and creatinine of 2 groups were determined before and after treatment. RESULTS: After 4 months of treatment, the total effective rates were 87.5% for combination group and 56.25% for ACEI group (P0.05). CONCLUSION: Shenyan kangfu tablet combined with benazepril can reduce proteinuria in patients with chronic nephritis,non-toxic side effect in short-term.

Objective To investigate whether there has any difference of gastric and small bowel transit time and completion rates between two capsule endoscopes with different size and weight. Methods Clinical data of patients who had undergone OMOM or MiroCam (smaller and lighter than OMOM) capsule endoscopy were retrospectively studied. Comparison of gastric and small bowel transit time and completion rates were made between the two kinds of capsule endoscopy. Results 1, 448 patients (628 in OMOM group and 820 in MiroCam group) were finally includ-ed. In patients with Crohn's disease or suspected Crohn's disease, gastric transit time of OMOM was significantly longer than that of MiroCam [(53.4 ± 52.6) minutes vs (41.1 ± 47.9) minutes, = 0.022]. In patients with gastroin-testinal bleeding, gastric transit time in OMOM was significantly shorter than that in MiroCam [(42.1 ± 44.8) minutes vs (62.0 ± 78.6) minutes, = 0.016). No significant difference in small bowel transit time or completion rate was found. Conclusions We conclude that the differences of gastric transit time, small bowel transit time and completion rates between the two kinds of capsule endoscopy with different size and weight are not significantly. Whereas, in patients with Crohn's disease or suspected Crohn's disease, gastric transit time of smaller and lighter capsule en-doscopy is shorter in patients with gastrointestinal bleeding, but longer of gastric transit time in smaller and lighter capsule endoscopy.

Objective To investigate the clinical and radiologic features of posterior reversible encephalopathy syndrome (PRES) associated with preeclampsia-eclampsia.Methods Twenty-one cases of PRES associated with preeclampsia-eclampsia were retrospectively studied on some aspects of clinical and radiologic features.Results The most common clinical presentations were seizures( 18 cases ),headache (16 cases),altered mentation (15 cases) and vision change (12 cases). Vasogenic edema lesions distributed in the parietal or occipital lobe (20 cases),the frontal lobes (14 cases),temporal lobes ( 11 cases), and basal ganglia (11 cases). The splenium involvement occurred in 4 cases,cerebellar hemispheres and brain stem involvement was prcscnted in 3 cases and 1 case separately. Three major patterns of PRES included dominant parietal-occipital (7 cases),the holohemispheric watershed (7 cases),and superior frontal sulcal (6 cases).Partial and asymmetric expression of PRES only occurred in 1 case.Conclusions The clinical features of PRES associated with preeclampsia-eclampsia are typical.Except the parietal or occipital lobe,involvement of the frontal lobe,temporal lobe and basal ganglia is common,followed by the occasional presence of the splenium,cerebellar hemispheres and brain stem.Three primary PRES patterns are noted,occasional with partial and asymmetric expression of PRES. Awareness of these typical and variable characteristics is important to recognize the PRES ncurotoxicity morc accurately when PRES present.

Objective: To investigate the effect of losartan on angiotensin II (Ang II) expression and myocardial remodeling in myocardial infarction (MI) rats’ model.
Methods: A total of 32 SD male rats were divided into 4 groups, Sham operation group, MI group, MI with losartan 10mg/(kg·d) group and MI with losartan 20mg/(kg·d). n=8 in each group. MI model was established and the electrocardiogram changes before and after MI were recorded, hemodynamic indexes were detected at 4 weeks after MI, pathological changes of myocardial tissue were examined by HE staining. The myocardial mRNA and protein expressions of ACE2 and Ang II were detected by RT-PCR and Western Blot analysis.
Results: Compared with Sham operation group, MI group showed increased LVMI and decreased LVEF P<0.05;the above changes were getting better in both MI with losartan groups in a dose-dependent manner. The pathological examination presented that MI group had myocardial cell swelling, fracture, hyperplasia and inflammatory cell infiltration, those damages were less in MI with losartan groups in a dose-dependent manner, Sham operation group had no pathological changes. Compared with Sham operation group, the mRNA and protein expressions of Ang II were obviously higher in MI group, P<0.05 and the expressions were decreased in MI with losartan groups in a dose-dependent manner;the mRNA and protein expressions of ACE2 were slightly increased in MI group and the expressions were further increased in MI with losartan groups in a dose-dependent manner.
Conclusion: Losartan could increase ACE2 expression and therefore, inhibit Ang II expression and improve the ventricular remodeling in MI rats’ model.

Objective To investigate the curative effect of the adenovirus-mediated fusion gene system driven by KDR promoter (AdKDR-CDglyTK) on a model of pancreatic cancer. Methods By using transplantation of the cultivated cells, human pancreatic cell line Capan-2 was injected subcutaneously on the back of nude mice to establish the animal model of the pancreatic cancer. Twenty nude mice were divided randomly and equally into four groups. The mice in group Ⅰ were injected with AdKDR-CDglyTK and 5-FC/GCV, those in group Ⅱ were injected with 5-FC/GCV, those in group Ⅲwere injected with AdKDR-CDglyTK and those in group Ⅳ received no any injection. AdKDR-CDglyTK was injected directly into the tumor and 5-FC/GCV was given by intraperitoneal injection. The observing parameters included common status, tumor bulk, tumor weight, inhibition rate of tumor growth, pathology, immunohistochemistry and treatment effect in each group. Electron microscopy was performed to observe the pathological changes of cells. The apoptotic cells in tumor were detected using the TUNEL assay. The expression of CDglyTK in tumors from each group was examined by RT-PCR. Results Tumor growth was dramatically inhibited in group Ⅰ. Tumor growth has no significant difference among groupⅡ , group Ⅲ and group Ⅳ. The apoptotic rate (34.20±4.60)% was significantly increased in group Ⅰ (F= 243. 22, P= 0. 00) and it had no significant difference among groupⅡ , group Ⅲ and group Ⅳ (P＞0.05). Conclusion AdKDR-CDglyTK with 5-FC/GCV can obviously inhibit the growth of human KDR-expressing pancreatic cell line Capan-2 and induce the cell apoptosis in vivo. The probable molecular mechanism lies in the facts that the system can cause a decline in the level of Bcl-2.

Objective:To investigate the influence of clinical outcomes and the risk factors of poor prognosis for preoperative nutritional risk in gastric cancer patients.Methods:A prospective study was performed in 140 patients with gastric cancer and the nutritional risk screening 2002 (NRS 2002) was done.The influence of preoperative nutritional risk on postoperative complications,hospital stay,ICU stay,hospital expenses,60 days readmission and mortality was analyzed,and the risk factors of perioperative complication were identified by univariate and multivariate analysis.Results:The significant difference (NRS 2002 ≥ 3 group vs.NRS 2002 ＜ 3 group) was observed in the rates of overall postoperative complications,pulmonary infection,overall hospital stay and postoperative hospital stay (P ＜ 0.05).The rates of anastomotic fistula,pleural effusion,60 days readmission,60 days mortality and hospitalization expenses in NRS 2002 ≥ 3 group were higher than that of NRS 2002 ＜ 3 group,but there were no differences between the two groups (P ＞ 0.05).By univariate and multivariate analysis,preoperative high cholesterol levels and preoperative nutritional risk are the risk factors of poor prognosis and postoperative complications.Conclusion:Preoperative high cholesterol levels and preoperative nutritional risk are independent risk factors of postoperative complications.

Objective To investigate the combined effects of somatostatin (SST) and cisplatin (DDP) on proliferation and apoptosis in gallbladder cancer cells,and to investigate the mechanism of the combined effects.Methods We performed immunohistochemistry to detect the PTEN expression in gallbladder cancer.We then investigated the combined effects of SST and DDP on cell proliferation in vitro with CCK-8 assay and analyzed the interaction between these two drugs using isobologram analysis.We also investigated the combined effects on cell proliferation in vivo using a xenograft nude mouse model.FITC-Annexin V/PI assay and TUNEL staining assay were performed to detect the proportion of apoptosis after combined treatment in vitro and in vivo.Reactive oxygen species and mitochondrial membrane potential were detected with DCFH-DA assay and JC-1 staining assay after the combined treatment.We finally detected the PTEN and p-AKT associated proteins using western blotting after the combined treatment.Results PTEN was abnormally decreased in gallbladder cancer tissues.PTEN expression was negatively correlated with cancer differentiation and was positively correlated with patients'survival time.DDP treatment decreased while combined treatment with SST induced PTEN expression and inhibited AKT activation by reversing resistance to DDP.Isolated SST or DDP treatment inhibited gallbladder cancer GBC-SD and SGC996 cell proliferation which was dose-dependence.These two drugs synergistically inhibited gallbladder cancer cell growth in vivo and in vitro.Isolated SST or DDP treatment induced cell apoptosis and combined treatment induced cell apoptosis the most.SST inhibited AKT activation but did not induce ROS.DDP induced ROS resulting in increased cell apoptosis.Either SST or DDP alone increased the levels of cytoplasmic cytochrome C protein and activated caspase-3.Conclusions SST enhanced growth inhibition by cisplatin in gallbladder cancer cells through inducing PTEN expression.This study provides the theoretical basis for further combined clinical chemotherapeutic applications.

Theδ13 C values of volatile organic compounds ( VOCs) in various emission sources and ambient air were analyzed by using thermal desorption coupled with gas chromatography and isotope ratio mass. The lowest sample concentration and peak shape quality needed for high precision and accurate analysis were investigated. Fuel evaporation ( gasoline and diesel) , vehicle exhaust, solvent evaporation, dining fumes and ambient air of different functional zones of Xiamen city were collected using Tenax TA tube, and the significant differences in δ13 C values of VOCs between these sources were observed. The δ13 C value of gasoline exhaust ( 97 # ) was heavier (-25 . 84‰) than that of dining fumes (-30 . 26‰) and theδ13 C values of fuel evaporation were heavier than that of vehicle exhaust after combustion. The average δ13 C value of atmospheric VOCs in Xiamen was at the level of -27 . 03‰ to -25 . 40‰, which was close to the δ13 C value of the evaporation and exhaust of gasoline and diesel, indicating that the VOCs in the atmosphere of Xiamen was highly influenced by transportation related sources.
