Objective To study three single nucleotide polymorphisms (SNP), SNP-43, -19 and - 63 of calpain-10 (CAPN10) gene in pregnant women with glucose metabolism disorders and their relationship with the risk of these disorders. Methods Totally, 270 pregnant women including 156 with an abnormal oral glucose tolerance test (study group) and 114 healthy controls were selected among those delivered at the Department of Obstetrics and Gynecology, Peking University First Hospital from Jan. 2005 to Dec. 2006. The SNP of CAPN10 gene at posifons 43, 19, and 63 were analyzed by primer-introduced restriction analysis-polymerase chain reaction (PIRA-PCR). Results (1) The frequencies CAPN10 SNP-19 2R/2R genotype (26.9% ,42/156) and 2R allele (48.9%, 152/312 ) were higher than those in controls (12.3% ,14/114 and 36.8% ,84/228, respectively; P=0.012, 0.006). (2) Stratified analysis according to family history of diabetes mellitus showed the proportion of the CAPN10 SNP-19 2R/2R+2R/3R genotypes (83% ,47/57) in the study group were significantly higher than that of control group (52%,11/21 ; P=0.009), and the proportion of SNP-63 T/T + T/C genotypes(47% ,27/57) in study group were significantly higher than that of control group (14%, 3/21 ; P=0.026) among those with positive family history. (3) The combined effect of CAPN10 SNP-43, -19 and -63 on glucose metabolism disorders was analyzed by comparing with the other haplotypes and showed that the haplotype 121 distribution in study group was significantly higher than those in controls(P=0.036), and 221 haplotype was significantly lower than controls (P=0.042). Conclusions (1) CAPN10 SNP-19 is associated with glucose metabolism disorders in pregnant women. And 2R allele might be the risk factor. CAPN10 SNP-19 2R/2R +2R/3R and SNP-63 T/T + T/C genotypes might increase the risk of glucose metabolism disorders in women with positive family history. Haplotype 121 might increase the risk of glucose metabolism disorders in pregnant women and 221 be a protective factor.

Objective To investigate the anti-virus effect of baicalein on influenza A virus in vivo.Methods NIH mice were randomized into the normal control group,model group,virazole group(at the dose of 0.07g?kg-1?d-1),high-,middle-and low-dose baicalein groups(100,10 and 1 ?g?kg-1?d-1 respectively).Mice infected models were induced by intranasal drip of influenza A virus strain FM1.The lung index,inhibitory rate of lung index,survival rate and death prevention rate as well as the pathological changes of lungs were observed.Results Compared with the normal control group,the lung index and survival rate were decreased(P

Objective To investigate the relationship between the resistance of the Klebsiella pneumoni-ae and the Klebsiella pneumoniae plasmid pNDM-LJ carrying blaNDM-1 by high-throughput DNA sequencing. Methods High-throughput DNA sequencing was carried out by the Illumina Miseq platform , and sequencing data were assembled by Edena software. Contigs were annotated by the RAST server and analyzed by the BLAST server. Results The plasmid pNDM-LJ was 54-kb in size with a GC content of 49%. The plasmid encoded 52 putative functional genes and belonged to the IncX3 group in incompatible classifications. Analysis of the plasmid sequence revealed high similarity with other IncX3 plasmids. The blaNDM-1 gene was located in a complicated gene environment possibly constructed by several transposition events. The 5′ and 3′ ends of the blaNDM-1 gene were adjacent to the ISAba125 and IS 26 respectively , forming a 10.8-kb transposon-like structure. Conclusion The plasmid pNDM-LJ carried the blaNDM-1 gene being resistant to carbapenems and played a possibly impor-tant role in transmission of blaNDM-1 in China.

Objective To investigate the prevalence and associated factors of fecal incontinence (FI) and urinary incontinence (UI) in postpartum Chinese women.Methods Questionnaires about FI and UI symptoms were completed via telephone interviews conducted within six months after delivery.Multi-variant Logistic analysis was applied for relation between delivery mode and FI or UI.Results (1) Two thousand and twelve postpartum women were admitted into this study,among which 14 (0.7％) had FI within 6 months after delivery.Logistic regression analysis showed that FI was significantly associated with forceps delivery (OR =20.09,95 ％ CI:3.64-110.90,P =0.000),and mediolateral episiotomy (OR=6.11,95％ CI:1.29-28.80,P=0.024).(2) Among the 2012 women,the prevalence of UI,stress urinary incontinence (SUI),urgent urinary incontinence (UUI)and mixed urinary incontinence (MUD was 10.04％ (n=202),8.15％ (n=164),0.94％ (n=19)and 0.94 ％ (n =19),respectively.Logistic regression analysis found that SUI prevalence was related to maternal age (OR =1.07,95％ CI:1.04-1.11,P =0.000),maternal weight before delivery (OR=1.04,95％ CI:1.02-1.06,P=0.001),neonatal head circumference (OR=1.20,95％ CI:1.05-1.39,P =0.010),mediolateral episiotomy (OR =4.96,95 ％ CI:3.05-8.07,P =0.0005 ),spontaneous vaginal delivery (OR=5.22,95％ CI:2.53-10.76,P=0.000) and forceps delivery (OR=9.20,95％ CI:4.07-20.79,P=0.000).UUI was related to maternal weight before delivery (OR=1.51,95％ CI:1.12-2.05,P=0.008).MUI was related to maternal weight before delivery (OR=1.06,95％ CI:1.00-1.11,P=0.049),duration of second stage of labor (OR=1.01,95％ CI:1.00-1.03,P =0.010),mediolateral episiotomy (OR =7.76,95％ CI:1.42-42.52,P=0.017) and forceps delivery (OR=15.21,95％ CI:1.61-143.44,P=0.018).(3) The prevalence of SUI was higher at 4 days and 42 days after delivery (7.95％ and 9.10％).Conclusions (1) F1 and UI prevalence is lower in this study than in other reports.(2) Vaginal delivery is a risk factor for women's FI and UI,especially forceps delivery and mediolateral episiotomy.(3) Maternal age,pre-delivery weight,newborn head circumference,spontaneous vaginal delivery,forceps delivery and mediolateral episiotomy might increase the risk of UI.

Objective To investigate the spatiotemporal expression patterns and the relationship of α-sarcomeric actin(α-SCA) ,α-smooth muscle actin(α-SMA) and intermediate filament protein desmin with the maturation of the prenatal and the neonatal mouse hearts. Methods Serial sections of the embryo mouse and the neonatal mouse hearts were immunostained with antibodies against α-SCA, α-SMA and desmin. Results Ventricle and outflow tract of embryonic day(ED) 9 heart showed stronger expression of α-SCA and α-SMA, but desmin expression was lower. In the atrium, the expressions of α-SCA and α-SMA were restricted to the dorsal and ventral walls. In the sinus venosus, only a few weakly stained α-SCA positive cells were detected. No desmin expression was found in the atrium and sinus venosus. The expressions of α-SCA, α-SMA and desmin were increased to their highest level at ED 12. The higher expression of α-SCA remained to the postnatal stages. After ED 12, the expressions of α-SMA and desmin gradually decreased in different parts of the heart, but their expressions in the right ventricle persisted longer. After birth,desmin expression was mainly concentrated in the Z lines of I bands and intercalated disks. Conclusion The presence of spatiotemporal differences in the expression of α-SMA and desmin reveals regional differences in cardiomyocyte maturation in various parts of the embryonic mouse heart. The right ventricle shows a relatively slow pace of maturation. The α-SMA may contribute to a peristaltoid contraction pattern of the embryonic myocardium with a slow shortening speed, and a relatively higher level of desmin is required for the maturation of the sarcomere.
