The paper is to systematically evaluate the efficacy and safety of Deng Zhan Xi Xin injection ( DZXXI) as an adjuvant treatment for patients with angina pectoris. The Cochrane Library, Medline, EMbase, CBM, CNKI, VIP, and Wan fang Data base were searched. Randomized controlled trials (RCTs) of DZXXI combined with western medicine routine treatment versus western medicine routine treatment alone for angina pectoris patients were all included. All trials were assessed according to the Cochrane Reviewer' s Handbook 5.1 for Systematic Reviews of Intervention and Meta analyses were performed by RevMan 5. 2 Software. A total of 30RCTs (3 086 patients including 1 572 patients of treatment group and 1 514 patients of control group) were included. Meta-analysis of treatment group compared with control group showed superior effect over reducing cardiovascular events ( OR = 0.33; 95% CI: [0.16, 0.67], P = 0.002, improving effective rate of DZXXI as adjuvant treatment for angina pectoris patients (OR = 3.97; 95% CI: [3.15, 5.02]; P < 0.000 010 and electrocardiogram curative effect (OR = 2.21; 95% CI; [1.83, 2.68]; P < 0.000 010. Funnel figure seemed that there was publication bias. The current limited evidence showed that when compared with the control group, treatment group was superior in improving patients with angina pectoris. But based on the limitations of the study, rigorous design with long follow up clinical trials are necessary for further evidence.

Objective To evaluate the diagnostic value of EUS in patients with chronic abdominal pain of suspected pancreatic origin.Methods The EUS findings and related clinical data of 106 patients with chronic abdominal pain of suspected pancreatic origin(excluding the patients with suspected pancreatic malignancies)from 1991 to 2004 in PUMCH were retrospectively analyzed.Results(1)The principal dis- ease interpreting the chronic abdominal pain of suspected pancreatic origin(excluding pancreatic malignan- cies)was chronic pancreatitis(CP)(57.5%),the following contributions were other pancreatic diseases (18.9%)and unknown diseases(11.3%).(2)The sensitivity and specificity of EUS for diagnosing CP was 95.1% and 64.4% respectively,the positive predictive value(PPV)and negative predictive value (NPV)was 78.4% and 90.6% respectively.(3)Abhormalities of pancreatic parenchyma structure based on EUS were the main findings(90.2%)in patients with CP and non-homogeneous echo pattern combined with hyper echoic dots or calcification was the predominant feature(52.5%).The value of isolated inhomo- geneity and focal enhanced eehogenicity for diagnosing CP were limited(P＞0.05).Abnormalities of pan- ereatic ductal system were presented in 63.9% of patients with CP and dilation of pancreatic duct was the major feature(34.4%).CP with focal mass(inflammatory pseudotumor)was usually presented as hypo e- choic mass in the pancreatic head based on EUS(90%),which was similar to the EUS feature of pancreatic cancer.(4)The general accordant rate based on EUS with ERCP or BT-PABA were 77.8% and 70.4% re- spectively,and the correct rate based on combine diagnosis were 100% and 95.2%.Conclusion CP is the main source of chronic abdominal pain of suspected pancreatic origin(excluding pancreatic malignancies). EUS has good sensitivity but inadequate specificity for diagnosing CP,while ERCP may be more sensitive than EUS for detecting pancreatic ductal lesions.Pancreatic parenchymal abnormalities contribute the major EUS features of CP but the value of isolated inhomogeneity and focal enhanced echogenicity for diagnosing CP are limited.

Chlorogenic acid displays several important roles in the therapeutic properties of many herbs, such as antioxidant activity, antibacterial, antiviral, scavenging free radicals and exciting central nervous system. Only about one-third of chlorogenic acid was absorbed in its prototype, therefore, its gut metabolites play a more important role in the therapeutic properties of chlorogenic acid. It is necessary to consider not only the bioactivities of chlorogenic acid but also its gut metabolites. This review focuses on the potential activities and mechanisms of chlorogenic acid and its gut metabolites on central nervous system diseases.

This study aims to investigate the effect of total flavones of Fructus Chorspondiatis (TFFC) on the mRNA and protein expression of collagen type I and III of rat cardiac fibroblasts (CFs) induced by angiotensin II (Ang II), and explore its anti-myocardial fibrosis molecular mechanism. Neonatal rat CFs were prepared from Sprague-Dawley rats (1-3 d after birth). The expression of collagen type I and III mRNA and protein were measured by RT-PCR and Western blotting, respectively. The study showed that stimulation of neonatal rat CFs with 100 nmol.L-1 of Ang II for 72 h resulted in a significant increase of the expression of collagen type I and III mRNA and protein. The changes on the expression level were blocked by TFFC. The results demonstrated that TFFC can inhibit myocardial fibrosis induced by Ang II in rats, which is probably associated with the collagen type I and III mRNA and protein levels up-regulated by Ang II, and TFFC was shown to decrease the expression levels of collagen type I and III mRNA and protein.

Objective To investigate the clinical features and management of pancreatic disease- associated portal hypertension.Methods A retrospective analysis was carried out in patients with portal hypertension complicating with pancreatic diseases in our hospital from January 1986 to April 2005. Medical records of these patients were reviewed,including data of demographics,etiologies,venous involvement,clinical presentation,laboratory tests,imaging studies,therapeutic modalities and out- comes.Results There were 59 cases of portal hypertension resulted from pancreatic diseases in our hos- pital,accounting for 4% of all portal hypertension in 19 years.The underlying pancreatic diseases were chronic pancreatitis(21 cases,35.6%),pancreatic carcinoma(20 cases,33.9%),acute pancreatitis (8 cases,13.6%),pancreatic pseudocyst(3 cases,5.1%).Of the 40 patients whose venous involve ment was identified,splenic vein obstruction occurred in 27 cases(67.5%),followed by portal vein obstruction(16 cases,40.0%).Mild or moderate splenomegaly was present in 48 cases(81.4%),with leukocytopenia as the most common manifestation of the 31 cases(52.5%)of concomitant hyper- splenism.Forty-five patients(76.3%)developed gastroesophageal varices(including 35 isolated gastric varices),among them,19 had bled(32.2%).Conservative treatment was effective in controlling acute bleeding,but could not prevent re-bleeding.Splenectomy was performed in 18 patients,mainly because of gastrointestinal hemorrhage.No postoperative bleeding occurred in the period of follow-up from 8 months to 9 years.Conclusions Pancreatic diseases may compromise portal vein and its tributaries, leading to generalized or regional portal hypertension.Pharmacological therapy can effectively control acute variceal bleeding,while surgical treatment is the appropriate procedure of choice in case of hemor- rhage recurrence.

Bacterial disinfectant resistance is the phenomenon that minimal inhibitory concentration or minimal bactericidal concentration of a certain disinfectant increases after a certain bacterium contacts with it many times. It exists widespread. Many species of bacteria are may resistant to a certain disinfectant, and a species of bacterium is may resistant to many disinfectant Disinfectant selectivity pressure is the extrinsic agent of bacterial disinfectant resistance. Resistance mechanisms include bacterial biochemistry structure, genetics pathway and enzymology pathway. There is relationship in disinfectant resistance and drug resistance. We should strengthen study and monitoring, enact unified standard and application specification to reduce bacterial disinfectant resistance.

The effects of surfactants on the production of cellulase by Trichoderma viride in liquid substrate fermentation process were investigated. Straw was used as the sole carbon source and the surfactants were biosurfactant rhamnolipid from Pseudomonas aeruginosa and Tween 80. The changes of FPA,CMCase,Avicelase and surface tension with time were analyzed under different concentrations of the two surfactants. The results showed that the surfactants can enhance the enzyme activity of Trichoderma viride. The FPA,CMCase,Avicelase were promoted 1.08,1.6 and 1.03 times higher than the controls by rhamnolipid. The enhancement of the enzyme activity by rhamnolipid was much higher than that of Tween 80. At the same time,rhamnolipid was not degraded prior to other substrate.

Objective To explore the association between ambient average temperature and hospital emergency room visits for cardiovascular diseases(International Classification of Diseases,Tenth Vision ICD-10:I00-I99) in Beijing,China.Methods Data was collected on daily hospital emergency room visits for cardiovascular diseases from Peking University Third Hospital,including meteorological data(daily average temperature,relative humidity,wind speed,and atmospheric pressure) from the China Meteorological Data Sharing Service System,and on air pollution from the Beijing Municipal Environmental Monitoring Center.Time-stratified case-crossover design was used to analyze data on 4 seasolls.Results After adjusting data on air pollution,1 degree(℃) increase of ambient average temperature would associate with the emergency room visits of odds ratio(Ors)as 1.282(95%CI:1.250-1.315).1.027(95%CI:1.001-1.055),0.661(95%CI:0.637-0.687),and 0.960 (95%CI:0.937-0.984) in spring,summer,autumn,and winter respectively.After controlling the influence of relative humidity,wind speed,and atmospheric pressure,1℃ increase in the ambient average temperature would be associated with the emergency room visits on Ors value as 1.423 (95%CI:1.377-1.471).1.082(95%CI:1.041-1.124),0.633(95%CI:0.607-0.660)and 0.971(95%CI:0.944-1.000) in spring,summer,auttmm,and winter respectively.Conclusion These data on outcomes suggested that the elevated level of ambient temperature would increase the hospital emergeney room visits for cardiovascular diseases in spring and summer while the elevated level of ambient temperature would decrease the hospital emergency room visits for the cardiovascular diseases in autumn and winter,suggesting that patients with cardiovascular diseases should pay attention to the climate change.

The effect of magnetic Fe3O4 particles on cellulase in the enzymatic hydrolysis of sunflower seed hull was studied in different adding ways and additive amount. In the process of enzymatic hydrolysis of sunflower seed hull, the variations of cellulase activity, reducing sugar concentration and cellulose conversion were evaluated. After the reaction, the analysis of pH and surface tension of hydrolysate were also used to determine the mechanisms of cellulase by the magnetic effect. The results indicated that after adding magnetic Fe3O4, the cellulase activity, reducing sugar concentration and conversion of cellulose had an increased between the 0.5 g/L and 2.0 g/L cases after 48 h. When the additive amount of magnetic Fe3O4 was 2 g/L, the cellulase activity at 60 h was improved significantly by 25.9%. It was found that the concentration of reducing sugar was increased from 6.950 mg/mL to 8.775 mg/mL with magnetic Fe3O4 1.5 g/L. Simultaneously, compared with the blank, which the conversion of cellulose was 47.932%, the maximum celluloseconversion of samples with adding magnetic Fe3O4 was 60.531%. Besides, the stability of cellulase activity adding in times was better than in one time. After the reaction, the final surface tension of hydrolysate with 1.5 g/L magnetic Fe3O4 was the lowest in comparison with the blank. However, no significant differences were observed in the final pH of the hydrolysate.

BACKGROUNDAn increasing incidence of Crohn's disease has been found in China in recent years. Our study has been focused on evaluating the diversity of the clinical manifestations of Crohn's disease in order to improve early diagnostic accuracy and therapeutic efficacy.

METHODSThirty patients with active Crohn's disease were enrolled and their clinical data, including diagnostic and therapeutic results, were analyzed. Endoscopy combined with histological examination of biopsy specimens provided characteristic features of the disease. Transabdominal bowel sonography (TABS) was used for detecting intestinal complications. Nutritional supportive therapy was given to 20 subjects with active cases of the disease.

RESULTSMost patients were young adults with a higher proportion of females to males (ratio: 1.14:1). The disease affects any segment or a combination of segments along with the alimentary tract (from the mouth to the anus). In this study, the colon and small bowel were the major sites involved. Recurrent episodes of abdominal pain in the right lower quadrant and watery diarrhea were the most common symptoms. Granulomas were identifiable in nearly one-third (30.8%) of all biopsy specimens. In moderate cases of the disease, remission was achieved more quickly through the use of oral prednisone therapy than with SASP or 5-ASA. Beneficial effects on the host's nutritional status were observed. Immunosuppressives were used on an individual basis and showed variable therapeutic effects. Sixteen patients had surgery due to intestinal obstruction or failure to respond to drug therapies. Rapid improvement after surgery was reported.

CONCLUSIONEndoscopy (with biopsy) and TABS were both crucial procedures for diagnosis. SASP (or 5-ASA) and prednisone were effective as inductive therapies. Azathioprine has demonstrable benefits after induction therapy with prednisone. Surgery, as an alternative treatment, provided another effective choice in selected patients.
