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.

ObjectiveTo investigate the interventive effect of xuebijing for injection combined with nalmefene hydrochloride injection in treatment of acute hepatocyte functional injury after severe thoracoabdominal injuries. MethodsClinal data of 169 patients with severe thoracoabdominal injuries who treated in The 253th Hospital of PLA between January 2009 and June 2013 were collected retrospectively. The trauma indexes of the 169 patients were all higher than 17 scores. Patients were divided into the intervention group (n=112) and the control group (n=57) according to their receptive treatment:patients of control group underwent traditional treatments such as antishock, hemostasis, and so on; but patients of intervention group received xuebijing for injection combined with nalmefene hydrochloride injection (intravenous infusion). Patients of intervention group were tested at the time of arriving at and leaving the emergency department to the inpatient department with alanine aminotransferase (ALT), aspartate aminotransferase (AST), tumor necrosis factor-α (TNF-α), lipopolysaccharide (LPS), and interleukin-6 (IL-6); the patients of control group were just tested at the time of leaving the emergency department to the inpatient department, then comparison of the indexes between the 2 groups was performed. ResultsIn intervention group, the levels of ALT, AST, TNF-α, LPS, and IL-6 after the interventive treatment were all lower than those of before interventive treatment (P<0.05). Compared with control group, there was no significant difference in the levels of ALT, AST, TNF-α, LPS, and IL-6 before the interventive treatment of intervention group (P>0.05); but the levels ALT, AST, TNF-α, LPS, and IL-6 were all lower after the interven-tive treatment (P<0.05). ConclusionsXuebijing for injection combined with nalmefene hydrochloride injection can evidently improve the acute hepatocyte functional injury after severe thoracoabdominal injuries, and improve the prognosis.
ObjectiveTo assess the therapeutic effect of arthroscopic microfracture surgery combined with oral glucosamine hydrochloride on osteochondritis dissecans of the knee. MethodsBetween January 2014 and June 2015, 24 patients with osteochondritis dissecans of the knee ready to undergo arthroscopic microfracture surgery were divided into experimental group (odd surgery sequence numbers) treated with arthroscopic microfracture surgery combined with oral glucosamine hydrochloride (480 mg/time, 3 times per day, from the first day to 3 months after the surgery) and control group (even surgery sequence numbers) treated with arthroscopic microfracture surgery. All the patients were discharged from the hospital after one week of rehabilitation exercises with rehabilitation equipment of lower extremity. Follow-up lasted for at least 6 months. The therapeutic effects of the two methods were assessed according to Tegner scores for motor function of knee joint and United States New York specialty surgical hospital (HSS) scores. ResultsThe symptoms of knee joint was alleviated significantly after the operation. The function of knee joint was improved significantly after 6 weeks. Tegner and HSS scores before surgery were not significantly different between the two groups (P>0.05). The Tegner scores were not significantly different between the two groups 6 weeks after surgery (P>0.05). The difference of Tegner scores were statistically significant between the two groups 12 and 24 weeks after surgery (P<0.05), and HSS scores of the experimental group improved better than the control group 6, 12 and 24 weeks after surgery, and the differences were statistically significant (P<0.05). ConclusionThe short-term effect of arthroscopic microfracture surgery combined with oral glucosamine hydrochloride is better than that of arthroscopic microfracture surgery in the treatment of osteochondritis dissecans of the knee.

Methods Cationic Vancomycin hydrochloride MVLs were prepared by double emulsion method, and the storing solution of Vancomycin was prepared. The analysis method of Vancomycin in vitro was established; the specificity, precision, and resorption rate were estimated. Reverse phase high performance liquid chromatography (RP-HPLC) was used to determine the concentration of Vancomycin, encapsulation efficiency, and release characteristics in vitro. The formulation and pharmaceutical process were optimized by single factor experiments and orthogonal experimental design with the factor of encapsulation efficiency as the criteria. The liposome morphology was observed by optical microscopy and transmission electron microscopy. The particle size and Zeta potential were determined by Malvern instrument. The stability was analyzed by dynamic analysis. Results An RP-HPLC method was established for the assay of Vancomycin. The analysis method was precise, simple, and reliable for the quality control of Vancomycin. Vancomycin hydrochloride MVLs were round and well-distributed. The average particle size and the encapsulation efficiency were 3.3 μm and 24.9%, respectively. Zeta potential was 24.53 mV, and 90.5% of Vancomycin hydrochloride was released after 264 hours in normal saline under 37℃. Cationic Vancomycin MVLs were stored for 1 month at 4 ℃, which mantained good stability. Conclusion Cationic Vancomycin hydrochloride MVLs have good appearance, high encapsulation efficiency, good stability, and significant sustained release properties.
ObjectiveTo observe the effectiveness of oral glucosamine hydrochloride and cupping therapy in the treatment of knee osteoarthritis. MethodsA total of 113 patients treated from February 2013 to February 2015 were randomly divided into three groups. All the three groups of patients underwent conventional treatment. The Cupping treatment group had 39 patients; 37 patients were treated with oral glucosamine hydrochloride, and another 37 patients accepted combined treatments of cupping therapy with oral glucosamine hydrochloride. Six weeks after treatment, pain degree of the patients and Lequesne index were used to assess the clinical efficacy of the treatments. Patients who had oral glucosamine hydrochloride underwent routine examinations of blood and urine, and received liver and kidney examinations. One year later, telephone follow-up was conducted to observe long-term efficacy. ResultsSix weeks after treatment, the combined treatment group was significantly better than the other two groups in terms of pain relief degree and effective rate (P < 0.05) . One year after treatment, the combined treatment group and the oral treatmentgroup had a significant advantage over the cupping treatment group (P < 0.05) , while there was no significant difference between the combined treatment group and oral treatment group. ConclusionsThe combined oral glucosamine hydrochloride and cupping therapy has an obvious short-term efficacy, which quickly relieves pain and improves the activity function of the knee. Oral glucosamine hydrochloride has a very good effect in the long-term treatment of osteoarthritis.

Objective To evaluate the clinical effectiveness and safety of gastrodin injection in the treatment of vertigo. Methods A multi-center, single-blind randomized controlled trial was designed to study 240 vertigo patients who were randomly allocated into the treatment and the control groups.Patients in the treatment group were treated with gastrodin injection 600 mg, intravenously guttae, daily for 7 days, while those in the control group were treated with betahistin 30 mg, intravenously guttae, daily for 7 days. All data were analyzed by SAS. CMH (Cochran’s and Mantel-Haenszel) method was used to compare the clinical effect between the two groups. Nonparametric statistics and t-test were used in baseline data analysis. Results ① The clinical effectivenes on vertigo: according to the intention-to-treat (ITT) analysis, the clinical control rate and effective rate in the treatment group (n=117) were 71.19% and 90.60%, respectively, while 54.17% and 77.50% were in the control group (n=120). A statistic significance difference was found between the two groups (P=0.005 and P=0.004 for control and effective rate respectively).According to the per-protocol population (PP) analysis, the clinical control rate and effective rate in the treatment group (n=116) were 72.41% and 91.38%, respectively, and were 54.70% and 77.78% in the control group (n=117). Statistic significance was found between the two groups (P=0.005 and P=0.004 respectively). ITT and PP analysis revealed similar results. ② The clinical effect on vestibular function: the clinical control rate and effective rate were 62.26% and 81.13% respectively in the treatment group (n=53), and were 42.37% and 76.27% in the control group (n=58). Statistic significance was found in the clinical control rate but was not found in the effective rates between the two groups (P=0.029 and P=0.504, respectively). ITT and PP analysis revealed the same results. ③ Adverse drug reactions (ADRs) were slight to moderate. ADRs rates were 8.33% in the treatment group (n=120) and 10.83% in the control group (n=120), respectively. No statistic significance was found between the two groups(P=0.538). Conclusions Gastrodin injection and betahistine injection are safe and effective drugs for vertigo; gastrodin injection is better than betahistine injection in relieving vertigo symptoms.
