To introduce the methods of the arthroscopy for exterior joint surgery, 45 cases have been subjected to surgical operations under arthroscopy in the exterior of joint during June 1999 to July 2002, including 14 for gluteus constrictor releasing by radiofrequency, 5 for removing of the screw and plate of the femur shaft, 3 for reduction and internal fixation for the fracture of humerus greater tubercle under the arthroscopy, 8 for removal of popliteal fosse cyst, and 15 for releasing carpal tunnel syndrome. The results showed that the function was satisfactory after reduction and internal fixation for humerus greater tubercle fracture, releasing of gluteus contracture and removing of popliteal fossa cyst by radiofrequency under arthroscopy. The symptoms of numbness and pain disappeared after carpal tunnel release by arthroscopy. No blood vessel and nerve injury, occurred and no recurrence and infection were found. In conclusion, the procedures of arthroscopy are with minimum invasion, less pain and easy for early rehabilitation for all treated cases. It can be used not only for joint disease but also be selective for the exterior joint surgery as well.

Objective To research the relationship between hypertensive disorder complicating pregnancy and serum free estriol 3 (FE3) and explore its impact on pregnancy outcome.Methods Clinical data of 117 hypertensive disorder complicating pregnancy and 165 normal pregnant women were retrospectivly analyzed.Chemiluminescence immunoassay determination of maternal serum FE3 also had been conducted.Then analyzing the correlation between hypertensive disorder complicating pregnancy and FE3 and its impact on pregnancy outcomes.Results LDL cholesterol and the level of creatinine of observation group were significantly lower than the control group(t =3.129,9.372,all P ＜ 0.05),while blood pressure,triglycerides,HDL,and 24-hour urinary protein content were significantly higher than control groug(t =7.361,2.398,2.833,all P ＜ 0.05).The FE3 level of the observation group were significantly lower than the control group (t =2.913,P ＜ 0.05).There was a significant positive correlation between the FE3 level of normal pregnant women and their gestational age (r =0.937,P ＜ 0.05).The probabilities of premature birth,premature rupture of membranes,postpartum hemorrhage,and neonatal asphyxia of observation group were significantly higher than amtrol group (x2 =3.912,3.879,4.267,6.935,all P ＜ 0.05).Conclusion There is a significant correlation between hypertensive disorder complicating pregnancy and FE3,which has an important significance on monitoring the health status of pregnant women and the fetal-placental function.

Objective To evaluate the efficacy and safety of the transobturator tension-free vaginal tape (TVT-O) surgery, a minimally invasive surgery for treating patients with the stress urinary incontinence (SUI). Methods 28 cases with female stress uri-nary incontinence treated by TVT-O procedure from April 2006 to June 2008 were retrospectively analyzed. The follow-up time is from 4 to 24 months. Results The mean operation time was 23 min (rang 10～30 min) and the mean intraoperative bleeding was 24 ml (range 15～40 ml). An indwelling catheter had been used for 3 d because of urinary retention in 3 cases. 24 patients(85.7%)reached complete control after the surgery,effective control in 4 patients(14.35%). Conclusions TVT-O surgery is an effective, safe, minimally invasive management to treat the stress urinary incontinence.

Objective: To obtain the serotype diversity and antimicrobial resistance of Salmonella isolates recovered from retail chicken carcasses for sale in six regions of China. Methods: From August 2010 to March 2012, each month 20 retail chicken carcasses including freshly slaughtered, chilled and frozen samples were collected from supermarkets and farmer's markets in 7 monitoring sites in Beijing, Jilin province, Inner Mongolia Autonomous, Shanxi province, Jiangsu province and Guangdong province, respectively. Samples were routinely collected for 12 months for each site. 1 680 chicken carcasses were collected in total and 2 629 Salmonella strains were isolated by PCR and biochemical method. Luminex xMAP method and classical slide agglutination method were carried out to determine isolates' serotypes. Minimal inhibitory concentrations (MICs) of 10 classes of antimicrobials including 14 agents were determined using broth micro-dilution method. Mocular methods were used to determine antimicrobial resistance genes of CIP-CTX-CT co-resistant isolates. Results: In all, 2 629 Salmonella isolates, there were 17 seorgroups and 58 serotypes, B and D1 were the dominant serogroups with rates of 34.7% (n=913) and 31.0% (n=815), Enteritidis (30.8%, n=810), Indiana (17.6%, n=463), Infantis (10.6%, n=278) were the top three serovars. We found 224 CIP-CTX co-resistant S. Indiana containing 3 colistin resistant strains, one of them carrying mcr-1 gene and being ESBLs positive, which demonstrated a nine multi drug resistance against 11 antimicrobials tested. Conclusion These data began to describe the complicated serovar diversity and heavy antimicrobial resistance of Salmonella isolates recovered from retail chicken carcasses in six regions of China. The findings highlight the emergence of ciprofloxacin and cefotaxime co-resistant S. Indiana and also a mcr-1 positive S. Indiana with heavy multi drug resistance.
