OBJECTIVE To investigate urogenital mycoplasma infection and its drug sensitivity in Beijing from Jul 2002 to Jun 2005. METHODS Mycoplasma were isolated and their antibiotic susceptibility was detected with Mycoplasma IST 2 Reagent Box from France. RESULTS Among 1806 cases 673 cases were with positive mycoplasma,accounting for 37.3% of the total.From them,Ureaplasma urealyticum(Uu) was positive in 541 cases(80.4%),higher than Uu combined with Mycoplasma hominis(Mh) infection(107 cases,15.9%) or Mh alone infection(25 cases,3.7%).The result of drug sensitivity test showed that Uu,Mh and Uu+Mh isolated from both sexes had different drug resistance.The most sensitive and stable antibiotics were josamycin(the rate of sensitivity was 98.7%) and pristinamycin(the rate of sensitivity 92.6%),the next was doxycyline(the rate of sensitivity was 91.8%).It seemed increasing sensitivity trend for tetracycline and erythromycin.The lowest rate of sensitivity was to ofloxacin and ciprofloxacin. CONCLUSIONS It is important to enhance the detection of drug resistance of mycoplasma,guide the drug use and prevent from producing antibiotic resistance.If antibiotic susceptibility testing of mycoplasma can not be tested,josamycin may be selected as the first choice to treat mycoplasma infection.

Objective To investigate the clinical effects of subemergency treatment of femoral intertrochanteric fractures in elderly patients.Methods From June 2013 through February 2014,47 patients older than 65 years were treated for femoral intertrochanteric fracture at our department and completed full follow-ups.Of them,20 received subemergency operation.They were 9 men and 11 women,with an average age of 72.2 ± 4.8 years.By the Evans-Jensen classification,there were 2 cases of type Ⅰ,5 of type Ⅱ,5 of type Ⅲ,5 of type Ⅳ,and 3 of type Ⅴ.The time from injury to surgery ranged from 0.5 to 1.7 days (average,0.8 days).The other 27 patients underwent selective operation.They were 11 men and 16 women,with an average age of 74.9 ± 5.7 years.By the Evans-Jensen classification,there were 3 cases of type Ⅰ,6 of type Ⅱ,6 of type Ⅲ,7 of type Ⅳ,and 5 of type Ⅴ.The time from injury to surgery ranged from 2 to 5 days (average,3.4 days).We compared the 2 groups in terms of in-hospital complications,fracture healing time,length of hospital stay,and hip scores at the last follow-up.Results All the patients were followed up for 12 to 15 months (mean,13.4 months).The rate of in-hospital complications in the subemergency operation group (35.0％,7/20) was significantly lower than that in the selective operation group (51.9％,14/27),and the length of hospital stay in the former (12.1 ± 1.6 days) was significantly shorter than in the latter (16.1 ± 1.8 days) (P ＜ 0.05).There was no significant difference between the 2 groups in fracture healing time (13.1 ± 1.8 weeks versus 13.6 ± 1.2 weeks) (P ＞ 0.05).According to the hip scores at the last follow-up,the subemergency operation group had 16 excellent,2 good,one fair and one poor cases (with an excellent to good rate of 90.0％) while the selective operation group had 21 excellent,2 good,2 fair and 2 poor cases (with an excellent to good rate of 85.2％),showing no significant difference between groups (P ＞ 0.05).Conclusion Subemergency operation can reduce not only in-hospital complications but also length of hospital stay for old patients with femoral intertrochanteric fracture.

OBJECTIVE:To consolidate the results of special antibacterial drug rectification so as to improve the rational medi-cation of antibacterial drugs. METHODS:By using the method of retrospective analysis,the antibacterial drug application data in 2011(before rectification and initial stage of rectification),2012(middle stage thereof)and 2013(later stage thereof)were sum-marized,compared and analyzed. RESULTS:After special rectification(Jan. 2011 vs. Dec. 2013),the utilization rate of antibacte-rial drugs in perioperative period for class I incision decreased from 80.42% to 24.49%. That of antibacterial drugs in emergency treatment decreased from 53.79% to 36.23%. The examination rate of microbial samples in inpatients who would use special-grade antibacterial drugs increased from 16.12% to 94.17%. The use intensity of antibacterial drugs by inpatients decreased from 70.28 DDDs/(100 persons·d) to 27.44 DDDs/(100 persons·d). The utilization rate of antibacterial drugs by inpatients decreased from 65.99% to 46.45%. CONCLUSIONS:Special rectification has remarkable effects on rational clinical application of antibacterial drugs. Regulation and evaluation should be strengthened to maintain the effects and continuously improvement should be made.

Objective To construct HaCaT cell lines stably expressing the wild type human GJB6 gene or its mutant by using a Tet-On lentiviral vector, and to lay an experimental foundation for studies on pathogenesis of hidrotic ectodermal dysplasia. Methods The wild-type human GJB6 gene and its mutant (A88V)were amplified by PCR, and then inserted into the Tet-on lentivirus plasmid to construct recombinant lentivirus vectors. The recombinants were identified by gene sequencing and enzymatic digestion. Cultured HaCaT cells were classified into three groups to be transfected with a negative control lentiviral vector (NC group), the lentivirus vector expressing the wild-type human GJB6 gene (WT group), or the lentivirus vector expressing the mutant human GJB6 gene (MU group). Puromycin was used to select HaCaT cell clones stably expressing the GJB6 gene which encodes the connexin 30 (Cx30)protein. The selected HaCaT cell clones were cultured with or without tetracycline for 48 hours, thereafter, real-time PCR(RT-PCR) was performed to detect GJB6 gene mRNA expression, Western-blot analysis to measure expressions of Cx30 and FLAG-tag proteins, and cell counting kit 8 (CCK8)assay to evaluate cellular proliferative activity. Results Enzymatic digestion and gene sequencing showed that recombinant lentivirus plasmids were successfully constructed. RT-PCR showed evidently increased mRNA expression of the GJB6 gene in stably transfected HaCaT cells. Moreover, the expression abundance of the GJB6 gene was 112.369 times higher in the WT group induced by tetracycline than in that without tetracycline treatment (P < 0.05), and 2.249 times higher in the MU group induced by tetracycline than in that without tetracycline treatment (P < 0.05). Western-blot analysis showed that Cx30 and FLAG-tag proteins were stably expressed in the WT group and MU group after induction with tetracycline, while neither of them was observed in the WT group or MU group without tetracycline treatment, or in the NC group. Significant differences were noted in cellular proliferative activity (expressed as the absorbance value at 450 nm)between the MU group with and without tetracycline treatment and between the WT group with and without tetracycline treatment at 4, 8, 12, 24, 36 and 48 hours (all P <0.05), but not between the NC group with and without tetracycline treatment at any of the above time points (all P >0.05). Conclusion HaCaT cell lines which stably express the wild-type GJB6 gene or its mutant(A88V)are successfully constructed.
