Objective To compare the efficacy and safety of insulin aspart (IAsp) versus regular human insulin (RHI) used in basal bolus (BB) or continuous subcutaneous insulin infusion (CSII) regimen in patients with diabetes mellitus in Chinese population.Methods We searched MEDLINE (via OVID),the Cochrane Library,Embase,PubMed,CBM,China National Knowledge Infrastructure (CNKI),and Wanfang databases from the beginning of the databases to November,2015.The randomized controlled trials comparing IAsp and RHI in DM were searched.The meta-analysis in newly diagnosed DM and treated DM was performed by RevMan 5.3.Results A total of 40 trials were included in this study,with 1087 newly diagnosed and 2395 treated DM patients.In both groups,IAsp was better in lowering 2 hours postprandial plasma glucose (2 hPG) after breakfast,lunch and dinner (For newly diagnosed population MD=-1.22,-1.70,-1.44;95%CI:-1.79~-0.64,-2.77~-0.63,-2.12~-0.75;for treated population MD=-1.19,-1.14,-1.03;95%CI:-1.39~-0.98,-1.27~-1.02,-1.25~-0.81) and fasting plasma glucose (For newly diagnosed population MD=-0.55,95%CI:-0.97~-0.12;for treated population MD=-0.24,95%CI:-0.44~-0.03) when compared with RHI.IAsp could shorten the time to achieve blood glucose target(For newly diagnosed population MD=-1.58,95%CI:-1.74~-1.42;for treated population MD=-1.73,95%CI:-2.10~-1.36) and reduce the risk of hypoglycaemia compared with RHI (For newly diagnosed population RR=0.33,95%CI:0.19~0.56;for treated population RR=0.44,95%CI:0.32~0.61) (P<0.05).Moreover,the total daily insulin dose was lower in IAsp therapy than in RHI therapy when using CSII regimen.Conclusion In Chinese DM patients,IAsp shows advantages in controlling 2 hPG,shortening the time to achieve blood glucose target and lowering the risk of hypoglycaemia when compared with RHI.

Objective To explore the perfect operation method for patients with vaginal vault prolapse.Methods Twenty six patients with vaginal vault prolapse who underwent transvaginal mesh repair by Prolift from January 2008 to June 2010 were analyzed retrospectively.Results The interval time between the first operation and this morbidity of ten patients who had underwent total hysterectomy for none FPFD ( ie:hysteromyoma et al) was ( 115.2 ±51.67) months,but the interval of sixteen patients who had underwent traditional repair operation (ie:transvaginal hysteromyoma and/or colporrhaphia anterior-posterior) for FPFD was (24.38 ± 13.43) months,which was markedly shorter ( t =6.75,P ＜0.01).The interval time between the first operation and the 2nd operation of the ten patients was ( 142.8 ±59.04) months,but that of the sixteen patients was (62.13 ± 44.51 ) months,which was significantly shorter ( t =3.97,P ＜0.01 ).Their age and POP-Q staging had no difference ( P ＞0.05).All operations were successfully performed by one gynecologist.The average operation time was ( 60.96 ± 7.88 ) minutes,the average blood loss was ( 119.23 ±27.53) ml,and there was no concomitant injury.All patients were followed up of 3 ～24 months.No vaginal erosion and prolapse recurrence happened,and the cure rate was 100％.Conclusions The Prolift system appeared to be a relatively safe and effective alternative to conventional surgeries for the treatment of vaginal vault prolapse.However,long-term follow-up still need to be performed.

Objective To investigate the drug tolerance of Acinetobacter baumanni and Stenotrophomonas maltophilia . Methods The antimicrobial susceptibility tests for 275 isolates of Acinetobacter baumanni and 107 isolates of Stenotrophomonas maltophilia from 2000 to 2004 were measured by MicroScan WarkAway 96 The chemotherapeutic effects of 18 cases of sequent infection with Acinetobacter baumanni and Stenotrophomonas maltophilia was analyzed. Results The resistance of the two species of bacteria to twelve antibiotics increased obviously during the last five years, especially from 2000 to 2001. The resistant rate of Acinetobacter baumanni to Cefepime、Cefotaxime、Ceftazidime and Ceftriaxonewas was 20~50% in 2000, but raised to 70%~81% in 2004. For Acinetobacter baumanni to Amikacin、Amp/sulbac、Ciprofloxacin、Gentamicin、Tobramycin and Trimeth/Sulfa, the resistant rate was 20%~40% in 2000, while 63~86% in 2004. The lowest resistant rate was to Imipenem, only 7% or so. The resistant rate of Stenotrophomonas maltophilia to Ciprofloxacin、Ceftazidime、ceftriaxone and Tobramycin was 25%、50%、0% and 0%, respectively, in 2000, but in 2004 year, was 76%、76%、95% and 95%, respectively. Stenotrophomonas maltophilia showed a high drug tolerance to other antibiotics. Conclusion To strengthen the monitoring of the antibiotic resistance of Acinetobacter baumanni and Stenotrophomonas maltophilia and the monitoring of sequential infection in Acinetobacter baumanni and Stenotrophomonas maltophilia is very important for clinic so as to choose antibiotic rationally and improve curative effect

BACKGROUND: Obesity is serious complex disease determined by multiple genetic factors. Body mass index (BMI) is a common phenotype for obesity. Although some candidate genes have been shown to be related with BMI variation, the underlying substantial relationship remains poorly understood.OBJECTIVE: To investigate whether estrogen receptor-α (ER-α) Pvull genetic polymorphism is associated with BMI variation.METHODS: In total 390 premenopausal women from a local population of Nanchang City in Jiangxi Province People's Hospital.Body weight and height were measured. All participants were genotyped at the ER-α Pvull locus using polymerase chain reaction-restriction fragment length polymorphism.RESULTS AND CONCLUSION: The ER-α Pvull genotype frequencies of PP, Pp and pp were 0.133, 0.485 and 0.382,respectively. The distribution of ER-Pvull genotypes was in accordance with Hardy-Weinberg equilibrium (HWE) (P ＞ 0.05).There was no significant correlation between ER-α Pvull genetic polymorphism and BMI variation (P = 0.338). These findings indicate that ER-α Pvull genetic polymorphism does not greatly affect BMI variation of premenopausal women in Nanchang region.
