Conclusion Pancreatic stellate cells are the key to pancreatic fibrosis,which are becoming the target for anti-fibrosis of the pancreas and treatment of chronic pancreatitis.

Objective To evaluate the relationship between the newly recominended chronic heart failue (CHF) marker-serum galection-3 (Gal-3)level and the prognosis of CHF by Meta-analysis.Methods The Chinese and English literatures about the relationship between Gal-3 and CHF prognosis were searched in PubMed,EMbase, Chinese Biomedical Literature Databases. All literatures were assessed by the inclusion and exclusion criteria. Hazard ratio (HR)and 95% confidence interval (CI)in each literature were extracted for Meta-analysis using STATA 12.1 software.The stability and reliability were evaluated by sensitivity analysis and publication bias analysis.Results Ten literatures complying with the requirements were included.The results of heterogeneity test were as follows:① When the influence of other factors were not excluded,heterogeneity test showed that P =0.000,I 2 =89.2%,heterogeneity existed in different studies,so statistics were combined using a random effects model.The combined HR of univariate analysis was 1.36 and 95% CI was 1.23-1.50.2.When the influence of other factors were excluded,heterogeneity test showed that P < 0.001,I 2 = 68.4%,heterogeneity existed in different studies,so statistics were combined using a random effects model.The combined HR of multivariate analysis was 1.17 and 95% CI was 1.07-1.26.3.Sensitivity analysis showed that when the study with the largest samples was excluded,the combined HR of univariate analysis was 1.54 and 95% CI was 1.32 - 1.77;the combined HR of multivariate analysis was 1.26 and 95% CI was 1.09 - 1.42.When the study with the smallest samples was excluded,the combined HR of univariate analysis was 1.34 and 95% CI was 1.20 - 1.47;the combined HR of multivariate analysis was 1.15 and 95% CI was 1.06-1.24.Conclusion The serum level of Gal-3 is increased significantly in the patients with CHF and it may be an independent risk factor for poor prognosis of the CHF patients.

OBJECTIVE: To evaluate the efficacy and safety of combined treatment with angiotensin II receptor blocker (ARB) and angiotensin converting enzyme inhibitor (ACEI) on diabetic kidney disease. METHODS: Randomized controlled trials (RCTs) were identified from CoChrane library, PubMed, EMbase, CNKI and VIP. Eleven RCTs involving 602 patients were included and analyzed with Rev Man 5.1 software. RESULTS: Compared with ACEI alone, combined treatment with ARB and ACEI was more effective on decreasing 24 h albuminuria, systolic pressure, average 24 h systolic pressure, diastolic pressure, and average 24 h diastolic pressure but with a high level of serum potassium. Compared with ARB alone, combined treatment with ARB and ACEI was more effective on decreasing systolic pressure and diastolic pressure. Compared with ACEI or ARB alone, we didn't get a definite conclusion that whether combined treatment with ARB and ACEI was more effective on decreasing 24 h proteinuria. CONCLUSION Based on this Meta analysis, combined treatment with ARB and ACEI is safer and has positive effect on diabetic kidney disease. However, small sample size and low methodological quality appeared in most of the trials included in this systematic review. Therefore, available evidence is insufficient to recommend a routine clinical application of combined treatment with ARB and ACEI on diabetic kidney disease.

Objective To analyse clinical efficacy of Frey and Bger procedures for chronic pancreatitis. Methods Clinical data of seventy patients of chronic pancreatitis undergoing Frey (32 cases) and Beger Procedures (38 cases) in our hospital from January 1999 to June 2009 were retrospectively analyzed,the rate of pain relief and endocrine and exocrine function of the pancreas in longterm follow-up were compared with each other. Results Overall perioperative morbidity for Frey group and Beger group was 12. 5% and 7.9% respectively (P =0. 52); Total pain relief rate in long-term follow-up was 96. 8% and 94. 7% respectively (P =0. 57). Postoperative de novo diabetes mellitus was 12. 5% and 21% ( x2 = 0. 90, P = 0. 34), Rate of steatorrhea was 12. 5% and 18.6% respectively ( x2 = 0. 15, P =0. 70). Conclusions Frey and Beger procedures were equally effective in improving symptoms of chronic pancreatitis and there were no significant differences in perioperative morbidity, rate of pain relief and function of endocrine and exocrine of the pancreas.

Objective To explore the expressions of interleukin (IL)-17A and its receptor IL-17RA in different degrees of malignant gliomas. Methods Fifty patients with glioma were collected in this study. Accordance to the World Health Organization Classification System, patients were classified by malignancy grade, including gradeⅠ(n=12), gradeⅡ(n=18), gradeⅢ(n=13) and gradeⅣ(n=7). The glioma tissue and peripheral blood samples of patients were obtained for detecting the expression levels of IL-17A and IL-17RA mRNA by using immunohistochemistry, quantitative real-time PCR. Western blot assay was used to detect expressions of IL- 17A and IL- 17RA in both the macroscopic (immunohistochemistry) and molecular levels (mRNA and protein). Results Immunohistochemical staining showed that the expression levels of IL-17A and its receptor IL-17RA increased with the increase of the malignant degree of gliomas. The mRNA levels of IL-17A and IL-17RA receptors in peripheral blood were up-regulated with the increasing malignancy grade of glioma (F=8.96, P<0.05;F=10.34, P<0.05). The mRNA levels of IL-17A and IL-17RA in glioma tissues were up-regulated with the increasing malignancy grade of glioma (F=11.21, P<0.05;F=14.11, P<0.05). The protein levels of IL-17A and IL-17RA in peripheral blood and glioma tissues were also up-regulated with the increasing malignancy grade of glioma (in peripheral blood:F=9.90, P<0.05;F=11.80, P<0.05;and in gliomas tissues:F=8.15, P<0.05;F=14.46, P<0.05). Conclusion The expressions of IL-17A and IL-17RA receptor are positively correlated with malignancy grade of glioma. These results provide some reference for clinical diagnosis of malignant gliomas.

OBJECTIVE:To study the influence of butylphthalide on the pharmacokinetics of aspirin in rats. METHODS:20 rats were randomly divided into control group(vegetable oil 0.4 ml/rat+aspirin 10 mg/kg)and trial group(butylphthalide 80 mg/kg+aspirin 10 mg/kg) intragastrically,once a day,for consecutive 10 days. Blood samples were collected before the last medication and 10,20,40,60,120,240,360,480,600 and 720 min after medication,0.2 ml each time. The blood concentration of drugs was determined by HPLC,and pharmacokinetics parameters were calculated by DAS 2.0 software. RESULTS:Main pharmacokinet-ic parameters of aspirin in control group vs. trial group were as follows as cmax of (28.68 ± 6.08) vs. (29.33 ± 4.25)μg/ml;t1/2 of (2.48±0.67)vs.(1.60±0.36)h;AUC0-720 min of(188.71±24.29)vs.(140.31±15.08)μg·h/ml;CL/F of(0.05±0.01)vs.(0.07± 0.01)L/(h·kg);there were significant differences in t1/2,AUC0-720 min and CL/F(P<0.05). CONCLUSIONS:Butylphthalide has no significant effect on the absorption and distribution of aspirin in rats,but can strengthen its metabolism and elimination.

Objective: The study investigated cognitive performance and brain function between treatment-resistant depression (TRD) and non- TRD patients to find potential neurobiological markers associated with refractoriness in depression patients. Methods: Fourteen TRD patients, 26 non-TRD patients and 23 healthy controls (HC) were included in the present study. The neural function of prefrontal cortex (PFC) and cognitive performance among the three group were examined using near-infrared spectroscopy (NIRS) during verbal fluency task (VFT). Results: Both TRD and non-TRD groups exhibited significantly worse VFT performance and lower activation of oxygenated hemoglobin (oxy-Hb) changes in the bilateral dorsolateral PFC (DLPFC) compared to the HC group. Within the TRD and non-TRD groups, VFT performance was no significant difference, but activation of oxy-Hb changes in dorsomedial PFC (DMPFC) in TRD patients was significantly lower than non-TRD patients. In addition, activation of oxy-Hb changes in right DLPFC were negatively correlated with the severity of depressive symptoms in depression patients. Conclusion Both TRD patients and non-TRD patients exhibited lower oxy-Hb activation in DLPFC. TRD patients exhibit lower oxy- Hb activation in DMPFC than non-TRD patients. fNIRS maybe a useful tool for predict depressive patients with or without treatment resistant.
