Objective To observe the clinical efficacy of Yishen Huayu Decoction for decreased ovarian reserve (DOR). Methods Eighty cases of DOR were randomly divided into 2 groups, with 40 cases in each group. The treatment group was treated with oral administration of Yishen Huayu Decotion, one dose a day. The control group was given DHEA, a time of 1 tablet, 3 times a day. 2 groups were observed for 3 menstrual cycles. The levels of basic follicle stimulating hormone (bFSH), basal estradiol (bE2), luteinizing hormone (LH) and serum anti-Müllerian hormone (AMH) were measured. The number of basal follicles and the peak systolic velocity (PSV) were monitored by transvaginal sonography. Quality of life assessment and basal body temperature were measured. Results The total effective rate was 85.00% (34/40) in the treatment group and 62.50% (25/40) in the control group, with statistical significance (P<0.05). After treatment, the levels of bE2 and bFSH decreased, and the levels of AMH, ovarian antral follicles and PSV increased, which were significantly different from those before treatment (P<0.05). After treatment, the levels of bE2 and bFSH in the treatment group were lower than those in the control group, and the levels of AMH, ovarian antral follicle and PSV were higher than those in the control group, with statistical significance (P<0.05). The recovery rate of basal body temperature was 77.50%(31/40) in the treatment group and 52.50%(21/40) in the control group, with statistical significance (P<0.01). After treatment, the scores of four dimensions of life quality, daily activities, health status and self-perception were significantly improved (P<0.01), and the treatment group was higher than the control group (P<0.01). Conclution Yishen Huayu Decotion can improve the ovarian reserve function and the life quality of patients with DOR.

Objective To investigate the association of two functional polymorphisms of tryptophan hydroxylase 2(THP2) gene,rs4570625 and rs4565946,with poststroke anxiety disorders.Methods Totally 112 poststroke anxiety patients and 246 non-anxious stroke controls were included and completed Hamilton Anxiety Rating Scale.DNA was extracted from blood and genotyped for the two polymorphisms of THP2 gene by polymorphism chain reaction.Results The G allele of rs4570625 was associated with the increased risk of poststroke anxiety.Both the GG genotype and G allele were observed to be significantly higher in female case than in control.No significant difference in genotype and allele firequencies of the rs4565946 was found among the groups.Patients with the G-C haplotype had significantly increased the risk of poststroke anxiety compared to controls.Conclusions Our findings suggest that these ftmctional polymorphisms in TPH2 gene may be involved in development of poststroke anxiety.

Objective To explore the effect of dietary fat acids on incretin and islet function in healthy adults .Methods Before each test, healthy subjects received a 1-week pre-experiment eucaloric diet .Fifteen subjects consumed two meals containing different fat acids , including high saturated fat acid ( HSF) and high monounsaturated fat acid ( HMF) .On two separate occasions,they underwent a minimum of 1-week washout between meals .At 0,30,60,120,180 and 240 min following meal intake, the plasma concentrations of gastric inhibitory polypeptide (GIP), glucagon-like peptide-1(GLP-1) and serum concentrations of glucose, insulin, triglycerides ( TG) and free fatty acid ( FFA) were measured.Results Postprandial glucose did not increase significantly following HSF and HMF meals (P>0.05).Compared with HMF meal, significant increase in AUCins240min,AUCTG240min and AUCFFA240minwas observed following HSF meal (P<0.05).Compared with HMF meal,a significant decrease in AUCGIP30min, AUCGIP240min, AUCGLP-1 30min and AUCGLP-1 240min was found following HSF meal (P<0.05).No significant difference was observed inΔI30/ΔG30 following HSF and HMF meals (P>0.05). AUCI/AUCG was significantly lower following HMF meal as compared with HSF meal (P<0.05).Conclusion This study demonstrates that the function of GIP ,GLP-1 andβcell is affected by the dietary fat acids in healthy adults .The HMF meal may stimulate GIP and GLP-1 secretion to a greater extent than HSF meal .

Objective To investigate the pathogens and their drug resistance of neonatal skin infection in Maternal-Neonatal Unit to provide evidence for rational selection of antibiotics.Methods Secretions of skin lesions from newborns with skin infections delivered in Maternal-Neonatal Unit,Department of Obstetrics of Beijing Daxing People's Hospital from Jan.2009 to Dec.2010 were collected,cultured and identified for bacterial serotype.Antibiotic resistances of pathogens were determined.Enumeration data was presented by frequency and rate.The difference between groups was compared with Chi-square test.Results Two hundred and six newborn skin infection cases were diagnosed,which accounted for 2.3％ of all newborns (n=9131) delivered in the hospital during the study period.Two types of skin infection were identified,impetigo (n=192,93.2％) and omphalitis (n=14,6.8％).Totally 154 pathogens were found,including 95 (61.7％) Gram-positive cocci and 59 (38.3 ％) Gram-negative bacilli.The major pathogens among Gram-positive cocci were Staphylococcus aureus (45/154, 29.2％), followed by Staphylococcus epidermidis and Staphylococcus haemolyticus.Staphylococcus was sensitive to Cefazolin,Amoxicillin/clavulanic acid and Piperacillin/tazobactam,while resistant to Penicillin,Ampicillin and Erythromycin.The major pathogens among Gram-negative bacilli were Enterobacter cloacae (19/154,12.3％),followed by Escherichia coli and Klebsiella pneumoniae.Drug resistance rate of Gram-negative bacilli was high in penicillin,aminoglycosides and cephalosporins,while they were sensitive to piperacillin/tazobactam,Ampicillin/sulbactam,carbapenems and Quinolones.Conclusions Gram-positive cocci are the main pathogens of neonatal skin infection in the Maternal-Neonatal Unit,and among which Staphylococcus aureus is the major pathogen.Multi-drug resistance is common in the identified pathogens.Attentions should be paid to use antibiotics reasonably according to drug sensitivity test.

Objective To investigate the effects of sevoflurane postconditioning on myocardial ischemiareperfusion(I/R)injury in patients undergoing coronary artery bypass grafting(CABG)with cardiopulmonary bypass(CPB).Methods Forty NYHA Ⅰ -Ⅲ patients of both sexes,aged 55-64 yr,with BMI ＜ 30 kg/m2,scheduled for CABG under CPB,were randomly divided into 2 groups(n = 20): control group(group C)and sevoflurane postconditioning group(group S).Anesthesia was induced with midazolam and/or etomidate,fentanyl and rocuronium.Patients were tracheal intubated and mechanically ventilated.Anesthesia was maintained with iv infusion of propefol and intermittent iv injection of fentanyl and pipecuronium.In group S,2% sevoflurane was inhaled continuously for 15 min immediately after aortic unclamping.After anesthesia induction,before CPB,10 min after the end of CPB,at the end of operation,and 6 and 24 h after operation,MAP,HR,CVP,mean pulmonary arterial pressure,pulmonary arterial wedge pressure,CO and S(v)O2 were recorded,and CI,SVI,systemic vascular resistance index and pulmonary vascular resistance index were calculated.Blood samples were taken from central vein before aortic clamping,at 6 h of reperfusion and 24 h after operation for determination of plasma creatine kinase(CK),creatine kinase isoenzyme(CK- M B)and lactate dehydrogenase(LDH)activities and tropenin I(TnI)concentrations.Myocardial tissues were obtained from right auricle before aortic clamping and at the end of CPB for observation of the ultrastructure and the severity of myocardial injury was assessed.Results There was no significant difference in hemodynamics and parameters of cardiac function between the two groups(P ＞ 0.05).Compared with group C,plasma CK-MB and LDH activities at 6 h of reperfusion and plasma CK activity and TnI concentrations at 24 h after operation were significantly decreased and the myocardial injury was significantly reduced after the end of CPB in group S(P ＜ 0.05).Conclusion Sevoflurane postconditioning can protect myocardium against I/R injury induced by CPB in patients undergoing CABG.

Objective To investigate the relationship between the anti-earthquake military rescuers' psychosomatic health and social support, and observe the effect of intervention to the army men who suffered troubles.Methods By cluster random sampling, 152 military rescuers and 139 army men not taking part in the rescues were investigated by Facility Psychosomatic Health Scale and Social Support Rating Scale. Mental intervention or medication was performed to those produced psychosomatic health. Results The scores of somatic symptoms,mental status,psychosomatic health and social support of military rescuers and the control group were (4.09±4.70) ,(2.18 ±3.16) ,(6.27 ±7.08) ,(6.14 ±4.20) and (2.11 ±4.16) ,(1.37 ±3.09),(3.47 ±6.55),(4.57 ± 4.17 )respectively, the difference was significant(P＜0.05). The somatic symptoms had significantly positive correlation with mental status in military rescuers (r=0.17～0.52, P＜ 0.05 or 0.01 ). Failure of social support had positive correlation with mental disorders (r=0.18～0.40, P＜0.05 or 0.01). The degree of social support was the main factor which had affected on the psychosomatic health of military rescuers. The somatic symptoms of military rescuers were apparently higher than their mental symptoms. Mental and pharmaceutical intervention showed good effect on them. Conclusion There is an apparent effect for military rescuers injured seriously psychosomatic health through medication or mental intervention.
