OBJECTIVE:To prepare anti-microbicide contraceptive gel and establish its quality control method. METHODS: The gel was prepared with octoxynol and policresulen as main ingredients and HPMC as matrix. The content of octoxynol in the gel was determined by HPLC,and the content of policresulen in the gel was determined by titration method. RESULTS:Prepared gel was well-proportioned and of good viscidity and its identification and test were up to the standard. The linear rang of octoxynol was 250~1 500 mg?L-1(r=0.999 6)with an average recovery of 100.84%(RSD=0.74%,n=9). The average labeled amount of policresulen was 106.64%(n=3). CONCLUSION:This preparation is feasible and stable in quality,and the quality control method is simple and accurate.

Objective To evaluate the clinical efficacy ofDuhuo Jisheng Decoction in treating liver and kidney deficiency syndrome of knee osteoarthritis (KOA) by ultrasound.Methods A total of 120 cases of KOA patients with liver and kidney deficiency syndrome were randomly divided into two groups (each contains 60 cases). Control group took hydrochloric acid glucosamine capsules, while treatment group tookDuhuo Jisheng Decoction additionally for 8 weeks. ESR, CRP, WOMAC, joint swelling scores, and TCM syndrome scores of the two groups were determined, and the sonographic characteristics of knee-joint effusion in patellar fabricius, synovial membrane, cartilage and bone erosions were compared before and after treatment.Results There were significant differences in ESR, CRP, WOMAC, joint swelling scores, and TCM syndrome scores between before and after treatment in both groups (P<0.05,P<0.01). The knee-joint synovial membrane got thinner after therapy in osteoarthritis patients, and the effusion in knee-joint also decreased. The vessel flow signals in knee-joint synovial membrane of osteoarthritis decreased after drug therapy (P<0.05,P<0.01).ConclusionDuhuo Jisheng Decoction can improve clinical efficacy of KOA with liver and kidney deficiency syndrome. Ultrasound can clearly observe the changes of effusion in patellar fabricius, and synovial membrane, and can provide good imaging assessment for the drug therapy for KOA patients.

Objective To investigate the clinical distribution and the drug resistances of Pseudomonas aeruginosa (PAE) during past 3 years in the 1st Affiliated Hospital of Kunming Medical University, and to provide evidence for clinical treatment of PAE infection.Methods The isolated PAE strains from 2010 to 2012 in the 1st Affiliated Hospital of Kunming Medical University were identified and antimicrobial susceptibility tests were performed using the MIC and the KB method,and thus, the ward distribution and the drug resistance rates and the changing trend were respectively analyzed by WHONET 5.5 software, and statistically analyzed with SPSS 17.0 SOFTWARE. Results Within the three years, a total of 208 strains, 260 strains and 280 strains of Pseudomonas aeruginosa were isolated separately in 2010,2011and 2012. A total of 746 PAE strains were isolated in 3 years,in which the most common specimens were sputum (79.8%), followed by the throat swab (7.6%) and the urine (6.2%) . When it came to the ward distribution , ICU was the primary, which accounted for (32.4%), followed by the department of cadre sanatorium (27.7%), the department of respiratory medicine (12.2%) and the department of neurosurgery (6.8%) . Besides imipenem, Cefoperazone-sulbactam and aztreonam, the others were obviously in a decreasing trend in drug resistances. In 2010, 2011 and 2012, the resistances rates of imipenem were ( 65.2%) , ( 74.2%) and ( 69.5%) , respectively, the resistances rates of Cefoperazone-sulbactam were (48.0%), (48.7%) and (55.8%), and the the resistances rates of aztreonam were (72.2%), (78.2%) and (72.4%) . Amikacin,piperacillin-tazobactam,Cefoperazone-sulbactam were the most active antimicrobial agents against P.aeruginosa. Conclusions The PAE is an important source of infection, ICUs are the focus of interest for resistance monitoring and control. Antimicrobial resistance of PAE is fairly serious. Clinicians should select appropriate antibiotic therapy based on sensitivity testing.The therapeutic strategy should he adapted according to the local ecology of resistance to control the epidemic of the drug- resistance strains and hospital infection.
