Objective To evaluate the effectiveness and safety of sarpogrelate hydrochloride for patients with peripheral arterial disease (PAD). Methods The randomized controlled trials (RCTs) on PAD treated by sarpogrelate hydrochloride were identified from CBM (1978 to September 2011), CNKI (1979 to May 2011), PubMed (1950 to May 2011), EMbase (1970 to May 2011) and The Cochrane Library (Issue 3, 2011). According to the criteria of the Cochrane Handbook, two reviewers independently screened the studies, extracted and cross-checked the data, and assessed the methodological quality. Then meta-analysis was conducted by using RevMan 5.0 software. Results Nine RCTs involving 522 patients and 532 limbs were included, with low methodological quality in most trials. The results of meta-analyses indicated that compared with the conventional treatment, sarpogrelate hydrochloride could reduce the area of ulcers (MD= –3.22, 95%CI –3.99 to –2.45), and it could increase the ankle-brachial index (SMD=0.49, 95%CI 0.07 to 0.91), blood flow of dorsalis pedis artery (MD=0.16, 95%CI 0.09 to 0.23) and pain-free walking distance (MD=200.87, 95%CI 3.39 to 398.36). Five trials reported the adverse effects of sarpogrelate hydrochloride, most of which were mild gastrointestinal symptoms. Conclusion Based on the review, sarpogrelate hydrochloride may have positive effect on patients with PAD. However, the evidence is not b enough due to the general low methodological quality, so the reliable conclusion has to be drawn with more high quality studies in future.
ObjectiveTo explore the clinical effect of lidocaine mucilage diluent and simethicone emulsion in gastroscopy examination, in order to provide effective drugs for gastroscopy. MethodsWe selected 201 outpatients and the inpatients who underwent gastroscopic examination between August and October 2014 as the research subjects. Based on the kind of drug, the patients were randomly divided into research group (n=100) and control group (n=101). Patients in the research group accepted lidocaine mucilage diluent, while those in the control group received simethicone emulsion. Then we observed and compared the definition of gastroscopy, adverse drug reactions, examination time and drug price between the two groups. ResultsThe frequencies of high, medium, and low definition of gastroscopy were respectively 63.00%, 34.00% and 3.00% among the patients in the research group, and 69.31%, 26.73% and 3.96% among patients in the control group; there was no significant differences between the two groups (Z=-0.854, P=0.393). The adverse reaction rates, testing time, and drug prices for the two groups were 0.99% vs.1.00% (P>0.05), (6.5±2.1) minutes vs.(6.6±2.0) minutes (t=0.458, P>0.05), and RMB (9.0±1.2) yuan vs.(42.8±2.8) yuan (t=227.644, P<0.05), respectively. ConclusionLidocaine mucilage diluent and simethicone emulsion both have good effect for gastroscopic examination, which can raise the gastroscopic definition, promote endoscopic operation and observation by doctors, shorten examination time, and reduce adverse drug reactions. Both are of great value in clinical application, and lidocaine hydrochloride mucilage diluent is cheaper, which can be widely used and promoted clinically.
ObjectiveTo discuss the effect of glucosamine-hydrochloride (Glu/Ch) in protecting and repairing the cartilage in blood-induced joint damage (BJD) in vivo. MethodsThirty-two adult New Zealand rabbits were randomly divided into 4 groups (n=8):high-dose Glu/Ch treated group (group A), low-dose Glu/Ch treated group (group B), positive control group (group C), and negative control group (group D). A joint bleeding model was established by blood injection into articular cavity in groups A, B, and C. Glu/Ch was given by gavage in groups A (250 mg/kg) and B (21.5 mg/kg) once a day for 8 weeks, and the same dosage of saline was given in groups C and D. The serum cartilage oligomeric matrix protein (COMP), serum chondroitin sulfate 846(CS846), and urinary C-terminal telopepide of type II collagen (CTX-II) were measured at 3 days, 7 days, 2 weeks, and 8 weeks after modeling. The expressions of cytokines such as interleukin 1β (IL-1β) and tumor necrosis factor α (TNF-α) in synovial fluid were analyzed by ELISA at 8 weeks after modeling. The expression of matrix metalloproteinase 13(MMP-13) was detected by immunohistochemistry. Alcian blue staining and Safranin-O staining were performed to calculate the percentage of the positive staining areas. The proteoglycan content was detected by semi-quantitative analysis in the articular cartilage. ResultsThe COMP concentration was significantly higher in groups A, B, and C than group D, and in groups B and C than group A at 3 days after modeling (P<0.05); no significant difference was found among groups A, B, and D at 7 days (P>0.05), and it was significantly lower in groups A, B, and D than group C (P<0.05); there was no significant difference among 4 groups after 2 and 8 weeks (P>0.05). Difference in CS846 concentration had no significance among 4 groups at each time point (P>0.05). The CTX-II concentration of groups A, B, and C was significantly higher than that of group D at each time point (P<0.05); it was significantly lower in group A than groups B and C at 7 days, 2 weeks, and 8 weeks (P<0.05). The TNF-α concentration of groups A and B was significantly higher than group D, and was significantly lower than group C at 8 weeks (P<0.05), but no significant difference was observed between groups A and B (P>0.05). The IL-1β concentration was significantly higher in group C than the other groups (P<0.05), and in group B than groups A and D (P<0.05), but there was no significant difference between groups A and D (P>0.05). The MMP-13 expression was significantly higher in group C than groups A, B, and D (P<0.05), in groups A and B than group D (P<0.05). A significant decrease in the area stained with Alcian blue and Safranin-O was observed in group C. There were significant differences in the percentage of the positive stained areas of Alcian blue and Safranin-O among 4 groups (P<0.05). The relative quantities of proteoglycan from small to large in order was groups C, B, A, and D, respectively, showing significant differences (P<0.05). ConclusionThe metabolism disorder of cartilage matrix and synovium inflammatory reaction can be observed in rat joint bleeding model. Glu/Ch has certain protective effect on the cartilage after BJD by down-regulating IL-1β, TNF-α, and MMP-13, as well as increasing proteoglycan content in the cartilage.

Objective To observe the protective effects of ambroxol hydrochloride ( AMB) on rabbit model of acute lung injury ( ALI) induced by oleic acid and explore its mechanisms. Methods The ALI model of rabbit was induced by oleic acid. Twenty-four Japanese white rabbits were divided into three groups randomly, ie. a normal saline group ( NC group) , an ALI group and an ALI plus ambroxol injection group ( AMB group) . The pathological changes and apoptotic index ( AI) in lung tissue, Caspase-3 activity in lung tissue homogenate were observed 6 hours after the intervention. Serum activity of superoxide dismutase ( SOD) and serum levels of malonaldehyde ( MDA) , interleukin-1β( IL-1β) , and tumor necrosis factor-α ( TNF-α) were measured simutanously. Results The pathological injury of lung in the AMB group was milder than that in the ALI group. Both the AI in lung tissue and Caspase-3 activity in homogenate in the AMB group were lower than those in the ALI group significantly ( P lt;0. 01, P lt;0. 05 respectively) , butwere higher than those in the NC group( both P lt; 0. 01) . The activity of SOD in serum measured 6 hours after AMB intervention was higher while the serum levels of MDA, IL-1βand TNF-αin serum were lower ( P lt;0. 01) than those in the ALI group significantly ( all P lt;0. 01) . Conclusions Ambroxol hydrochloride has protective effects on oleic acid-induced acute lung injury. The mechanisms may be related to inhibition of oxidative stress and suppression of cytokines synthesis ( IL-1βand TNF-α) , the activity of the Caspase-3,and the apoptosis of lung tissue.
