Objective: To analyze the connection between the age of the mother and the birth weight of the new born baby as well as the impact of weight index during pregnancy on the birth weight of the new born baby.Method: Analyze the weight of the 1301 new born babies delivered from January to December 2005 in the First Affiliated Hospital of Chongqing University of Medical Sciences;analyze 576 first time lying-in women who had normal vagina delivery in the First Affiliated Hospital of Chongqing University of Medical Sciences from January 1999 to July 2003,among which there were 184 samples of corpulence during early period of pregnancy with BMI equal to or higher than 24 and 152 samples of corpulence during confinement with BMI equal to or higher than 27.Observe the connection between the birth weight and the age and BMI of pregnant women.Results: Excluding gestational diabetes,non-full-month gestation,double and triple embryo gestation,the average birth weight of 1301 new born babies was 3396g with the average birth weight of 3453g for male babies and 3397g for female babies respectively,among which only those women at the age between 20 and 24 had the new born babies with the weight lower than the average.Compared the corpulent during early period of pregnancy with the compared group,the happening rate of huge baby is evident.Compared the corpulent during confinement with the compared group,the happening rate of huge baby is evident.Compared the weight increase equal to or higher than 15kg during early period of pregnancy with the weight increase lower than 15kg,the happening rate of huge baby is evident.Conclusion: Too young the age of the mother has negative impact on the development of fetus.Too much increase of weight during pregnancy results in increasing happening rate of huge baby.

Objective:To study the correlation between the bone morphogenetic proteins (BMP-2) and matrix metalloproteinase-9(MMP-9) in fetal membrane and premature rupture of membranes. Methods: 18 samples were selected separately from each of the following groups: puerpera with term pregnancy in labor, puerpera with term premature rupture of membranes(PROM), puerpera in preterm labor, puerpera with pre-tenm PROM and puerpera with term pregnancy not in labor (control group). After labor, fetal membranes in the rupture site were taken out. Immunobistochemistry and pathologic image multimedia operation system were adopted to semiquantitative analyze the area integrated optical density (AIOD) of the positive expression of BMP-2 and MMP-9. Results:①The AIOD of BMP-2 and MMP-9 positive expression in fetal membranes was higher in term pregnancy in labor group, term PROM group, preterm labor group and PROM group than that in control group. There was statistic difference ( P < 0. 0071). ②The AIOD of BMP-2 and MMP-9 in term PROM group was higher than that in term pregnancy in labor group(P=0.0065,P=0.0069), which was higher in PROM group than that in preterm labor group (P=0.0069, P = 0.0052) and term PROM group P=0.0037, P =0.0065),③There was obviously positive correlation between BMP-2 and MMP-9 expression in the fetal membranes in five groups. ( r_s =0.76159,P<0.0001). Conclusions: The expression of MMP-9 and BMP-2 is closely relevant to the repture of membranes. There is a correlation between BMP-2 and MMP-9 expression in fetal membranes.

Objective To investigate antimicrobial resistance,distribution,and carriage of carbapenemase genes of Acinetobacterbaumannii(AB)from two hospitals in Qingdao.Methods 145 AB isolates collected from two hospi-tals (78 from hospital A,67 from hospital B)were performed antimicrobial susceptibility testing,carbapenemase genes were amplified by polymerase chain reaction (PCR);homology analysis were conducted with enterobacterial repetitive intergenic consensus (ERIC)-PCR.Results AB from hospital A were generally resistant to 16 commonly used antimicrobial agents,with the lowest resistant rate of 3.85% to cefoperazone/sulbactam,followed by resist-ance rate of 16.67% to minocycline,resistant rates to the other antimicrobial agents were all>73% . AB from hos-pital B were generally resistant to 23 commonly used antimicrobial agents,but the resistance rates to minocycline and tigecycline were both 0,resistance rates to amikacin and levofloxacin were 23.88% and 38.81% respectively, resistant rates to the other antimicrobial agents were all >64% . All strains carried OXA-5 1 gene,the carriage rates of OXA-23 gene in carbapenem-resistant group were 86.76% (59/68)and 56.67% (34/60)in hospital A and B re-spectively,the difference was significant(χ2= 14.53,P<0.001);OXA-58 gene was detected in 3 isolates in hospi-tal A but not detected from hospital B. 145 AB strains were classified into 8 types,the major prevalence types were type A (n= 71)and E(n= 37);the major prevalence types in hospital A were type A (46.15% )and E(41.03% ), hospital B were type A (52.24% )and C (17.91% ).Conclusion Antimicrobial resistance of clinically isolated AB is serious and prevailed in two hospitals. OXA-23 and OXA-51 genes play an important role in AB resistance to car-bapenems.

Objective To observe the effect of Xuebijing injection on blood coagulation in patients with sepsis. Methods 300 patients with sepsis were randomly divided into control group and Xuebijing injection treatment group(each,150 cases). According to the guidelines of treatment for sepsis,the conventional treatment was given to both groups,and additionally Xuebijing injection 50 mL plus normal saline 100 mL intravenous drip was applied in the treatment group,twice a day for consecutive 7 days. Before treatment and after treatment for 3 days and 7 days,platelet count(PLT),four items of blood coagulation〔prothrombin time(PT),thrombin time(TT),fibrinogen (Fib)and activated partial thromboplastin time(APTT)〕,D-dimer levels and disseminated intravascular coagulation (DIC)incidence were observed in the two groups. Results Before treatment,the levels of Fib,PT,TT,APTT, PLT,D-dimer and the incidence of DIC had no significant differences between the two groups(all P>0.05);after treatment,the levels of PT,TT,APTT,D-dimer and the DIC incidence were significantly lower than those before treatment,while Fib and PLT were significantly enhanced after treatment,and on the 7th day after treatment,the changes in Xuebijing group were more obvious〔Fib(g/L):3.02±0.51 vs. 2.53±0.56,PT(s):13.82±1.91 vs. 16.03±1.68,TT(s):13.85±1.94 vs. 16.03±1.65,APTT(s):39.47±4.73 vs. 42.75±5.24,PLT(×109/L):118.10±15.80 vs. 99.77±15.67,D-dimer(mg/L):3.17±0.26 vs. 3.66±0.50,DIC incidence:5.3%(8/150)vs. 14.0%(21/150),P<0.05 or P<0.01〕. Conclusion Xuebijing injection can improve the hypercoagulable state and reduce the incidence of DIC in patients with sepsis.

HSP70 gene and protein expressions in PC12 cells were determined by reverse transcription-polymerase chain reaction (RT-PCR) and Western Blot. After being challenged with ischemia and hypoxia for 4 hours, the viability of cells was detected by methyl thiazolyl tetrazolium (MTT), the levels of lactic acid dehydrogenase (LDH) in cell supernatant were determined by LDH measurement test kit. The concentration of intracelluer calcium ([Ca2+]i) was assayed by flow cytometer. The activities of Na+-K+-ATPase, Ca2+-Mg2+-ATPase and total ATPase were measured by ATPase test kits.Results The expressions of exogenous HSP70 gene and protein were found by RT-PCR and Western Blot in the recombination lentivirus infection group. After being challenged with ischemia and hypoxia, the viability of cells in the recombination lentivirus infection group was increased significantly as compared with the lentivirus control group and non-infection group (A value: 0.575±0.020 vs. 0.395±0.014, 0.363±0.045,t1= 17.996,t2= 10.600, bothP< 0.001), the levels of LDH in culture medium and the concentration of [Ca2+]i were decreased significantly [LDH (U/L): 743.46±23.68 vs. 935.43±34.77, 962.89±26.68,t1= 11.179, t2= 15.044, bothP< 0.001; [Ca2+]i relative fluorescence: (31.60±2.43)% vs. (41.48±3.33)%, (40.40±3.05)%, t1= 5.853,t2= 5.502, bothP< 0.001], and the activities of Na+-K+-ATPase, Ca2+-Mg2+-ATPase and total ATPase were increased significantly [Na+-K+-ATPase (μmol·mg-1·h-1): 8.608±0.307 vs. 6.728±0.173, 6.450±0.091,t1=9.237,P1= 0.001,t2= 11.675,P2< 0.001; Ca2+-Mg2+-ATPase (μmol·mg-1·h-1): 10.523±0.036 vs. 7.910±0.209, 8.064±0.195,t1= 9.718,P1= 0.001,t2= 11.535,P2<0.001; total ATPase (μmol·mg-1·h-1): 17.041±0.324 vs. 14.150±0.182, 13.983±0.085,t1= 16.113,t2= 17.602, bothP<0.001]. There was no statistical difference in above indexes between lentivirus control group and non-infection group.Conclusion HSP70 can maintain the PC12 cells calcium homeostasis, which may be one of the important mechanisms of anti-apoptosis.
