Objective To evaluate the decreased level of serum inhibin B(INHB)treated by gunadotropin releasing hormone agonist(GNRH-a)in predicting ovarian response and pregnancy in in vitro fertilization-embryo transfer(IVF-ET).Methods The prospective study enrolled 124 women given by GnRH-a+recombine follicle stimulating hormone(rFSH)+human chorionic gonadotrophin(hCG)long term stimulation protocol undergone their first cycle of IVF-ET treatment.The following predictive factors were collected and analyzed,such as age,basal level of follicle stimulating hormone(FSH),the ratio of FSH/luteinizing hormone(LH),the concentration of INHB after down-regulation,total number of antral follicle count(AFC)and mean ovarian volume. Ovarian response was evaluated by the number of oecytes obtained.A multiple regression analysis and logistic regression model were used for all possible prognostic variables to evaluate the value of difierent hormones in predicting ovariall response and pregnancy after IVF-ET.Receiver operating characteristic(ROC) analysis was used to evaluate the level of INHB in predicting the number of oocytes obtained.The sensitivity and specificity were calculated at the discriminating cut-off point Results The concentration of INHB after down-regulation showed a highly significant positive correlations with the number of oocytes obtained(r=0.435,P<0.01).The multiple regression analyses showed INHB was the most significant predictor of the number of retrieved oocytes,but INHB was not associated with IVF-ET outcome significantly(P>0.05).ROC analyses showed INHB after down-regulation had the largest area under curve(AUC)0.933(95%CI:0.878-0.988).When a threshold of 15 ng/L of INHB was established,95.5%sensitivity and 50.0% specificity in ovarian response were observed.Conclusions The level of INHB Was the best factor in predicting ovarian response in IVF-ET.Decreased level of INHB Was the early sign of ovarian reserve function failure,however,useless in predicting IVF-ET outcome.

Objective To evaluate the effect of serum LH level on the day of superovulation start on the prolonged gonadotropin-releasing hormone ngonist therapy on the outcomes of in vitro fertilization and embryo transfer (IVF-ET) in patents with ovarian endometriomas. Methods 75 patients with ovarian en-dometriomas were treated by laparoscopic cystectomy or laparotomy cystectomy or ultrasound-mediated cysts puncture, and gonadotropin-releasing hormone agonist (GnRH-α) was given for 3 to 4 times every 28 days after the operation. Superovulation started after 14 ～ 84 days of the last injection. All the patients were di-vided into two groups according to the level of serum LH. Group A included 30 patients whose level of LH was less than 0. 5IU/L, and group B included 45 patients whose level of LH was over 0.5IU/L and less than 1.5IU/L. The outcomes of IVF-ET were evaluated. Results The total ampoules of Gn administration and the ampoules of hMG needed in group A[(32.28±7.7) ampoules, ( 12.0±8. 9) ampoules,]were sig-nificantly more than that in group B[( 25.84±7. 1 ) ampoules, ( 6. 19±7.4) ampoules, P < 0.05] . The successful embryo implantation rate in group A( 18. 1% ) was lower than group B(26. 7% ), and the differ-ence has statistical significance ( P <0. 05). Conclusion The low level of serum LH on the superovula-lion day on the prolonged gonadotropin-releasing hormone agonist protocol will increase the ampoules of Gn administration and decrease the successful embryo implantation rate of IVF-ET, thus LH should be a more important reference parameter of superovulation start.

Objective To investigate the effect of delighted thinking on improving negative emotion of depression patients. Methods 100 depression patients were randomly divided into the observation group and the control group with 50 in each according to admission sequence. Both groups was executed antidepressionant drugs treatment and routine psychiatric care simultaneously. The observation group was given delighted thinking training on the basis of above treatment. The emotional recovery of two groups was observed. Results There was significant difference on facial expression, communication and limbs language after executing delighted thinking training in the observation group. And there was significant difference on scores of Hamilton depression rating scale (HAMD) at discharge. Scores of Nurses' Observation Scale during early, middle and late stage of delighted thinking training greatly improved compared with those before training. Conclusions Delighted thinking contributes to throw off negative thinking pattern of self-denial, stimulate positive passion threshold, improve depressed mood and raise treatment effect for depression patients.

Objective: To study the effects of hydrolysed casein in different doses on plasma and liver antioxidant capacities in mice. Methods: Fifty mice were divided into 5 groups: control group, vitamin E group (VE), low dose of hydrolysed casein group (CH1), medium dose of hydrolysed casein group(CH2)and high dose of hydrolysed casein group(CH3). The mice were supplemented with 0.25ml normal saline,7.2 mg/ml Vitamin E,4,12 and 20 mg/ml hydrolysed casein respectively by gavage one time a day. The mice were euthanatized after ten days. The activities of SOD, GSH-PX and the level of MDA were determined. Results: Hydrolysed casein in different dosese vidently increased the activities of SOD and GSH-Px in serum, and reduced the level of MDA in serum and liver of mice; group CH3 significantly increased the activities of GSH-Px in liver. Conclusion: Different doses of hydrolysed casein could raise plasma and liver antioxidant capacities in mice, especially the high dose of hydrolysed casein.

Objective To explore the prevalence of nonalcoholic fatty liver disease(NAFLD)in patients with polycystic ovary syndrome(PCOS).MethodsA case-control study employing 60 non pregnant patients with PCOS and 60 non-pregnant patients without PCOS as control was conducted to compare the prevalence of NAFLD.Resuits The aminotransferase(ALT),fasting insulin and homeostasis model assessment of insulin resistance(HOMA-IR)levels were(29±15)U/L,(19±12)mU/L and 0.47±0.29 in PCOS group,which were significantly higher(P＜0.05)than corresponding parameters in control group[(15±13)U/L,(11±8)mU/L and 0.31±0.21)].The occurrence of insulin resistance and NAFLD was 63％(38/60)and 42％(25/60),higher than those in control group[35％(21/60)and 20％(12/60),P＜0.05].The increment of ALT was 40％(24/60)in PCOS group,higher than that of 3％(2/60)in control group(P＜0.01).Compared with patients witIlout NAFLD,patients with NAFLD had significantly increased body mass index(P＜0.01),waist-hip ratio,AIJT,C-reaction protein,fasting insulin,insulin and HOMA-IR levels 2 hours after oral glucose tolerance test(P＜0.05).Conchsion The increased prevalence of NAFLD in PCOS patients suggests an association between these two conditions and the necessity of hepatic screening among PCOS patients for potential NAFLD.

Objective To evaluate the effect of awake tracheal intubation with intubating larynegeal mask airway (ILMA) on stress responses of hypertensive patients.Methods Sixty hypertensive patients,aged 45-64 yr,with body mass index of 20.3-27.5 kg/m2,of American Society of Anesthesiologists physical status Ⅱ or Ⅲ,undergoing elective abdominal surgery under general anesthesia,were divided into 2 groups (n=30 each) using a random number table:direct laryngoscope group (group D) and ILMA group (group I).At 3 min after topical anesthesia (T1),while epiglottis and glottis were exposed with direct laryngoscope in group D or during ILMA insertion in group I (T2),immediately after completion of intubation (T3),when the maximum change in hemodynamics after intubation appeared (at about 15 s after tracheal tubes were placed,T4),and at 5 min after completion of intubation (T5),mean arterial pressure (MAP) and heart rate (HR) were recorded,and blood samples were collected for determination of plasma epinephrine concentrations by radio-immunity method.Successful intubation at first attempt was recorded.Results Compared with the parameters at T1,the MAP,HR and plasma epinephrine concentrations were significantly increased at T2-4 in group D (P＜0.01),and no significant change was found in the parameters mentioned above at the other time point in group I (P＞0.05).Compared with group D,the MAP,HR and plasma epinephrine concentrations were significantly decreased at T2-4 (P＜0.01),and no significant change was found in the success rate of intubation at first attempt in group I (P＞0.05).Conclusion Awake tracheal intubation with ILMA does not induce strong stress responses and is helpful in avoiding the occurrence of cerebrovascular accidents,thus increasing the safty of awake tracheal intubation in hypertensive patients.

Objective To observe the clinical therapeutic effect of oral solution of Huaixue Shenshu for treatment of patients with IgA nephropathy and explore its mechanism. Methods A prospective study was conducted. Forty patients with IgA nephropathy diagnosed by pathology were selected, and they were randomly divided into treatment group and control group, 20 cases in each group. The two groups were subjected to the routine treatment, and on this base, the control group also received cozaar 50-100 mg, while the treatment group additionally received oral solution of Huaixue Shenshu decoction (drug composition:Centellae herba 15 g, Sophorae Flos 20 g, Ecliptae Herba 20 g, Ligustri Lucidi Fructus 15 g, Cicadae Periostracum 15 g, Pyrolae Herba 20 g, Saposhnikoviae Radix 10 g, Astragali Radix 15 g, the above ingredients were immersed in water and boiled to form 200 mL decoction, as a dose, and then divided into two parts to take orally one of them each time, twice a day). Both groups took two therapeutic courses in total, 3 months constituting one course. After treatment, the integral changes of clinical symptoms and clinical efficacy were observed, and before treatment and 3 months and 6 months after treatment, the 24-hour urine protein, serum creatinine (SCr), and albumin (Alb) were measured in the two groups. Results Before treatment, there was no significant difference in integral of clinical symptoms between treatment group and control group (score: 18.42±5.41 vs. 19.95±6.25, P>0.05);after treatment, the integrals of two groups were significantly lower than those before treatment, and the degree of decrease in treatment group was more obvious (score: 6.35±2.11 vs. 9.45±3.55, P < 0.05). After treatment the total effective rate in treatment group was significantly higher than that in control group [75.0% (15/20) vs. 40.0% (8/20), P<0.05]. Before treatment, the differences in 24-hour urinary protein, SCr and Alb were not significant between the two groups (all P > 0.05); with the prolongation of treatment, the 24-hour urinary protein was decreased gradually, and Alb was increased gradually, reaching its peak after 6 months of treatment, and the changes were more obvious in treatment group [24-hour urinary protein (g):0.71±0.58 vs. 1.31±0.55, Alb (g/L):37.8±6.1 vs. 35.5±5.2, both P<0.01]. No significant difference in SCr was found before and after treatment between the two groups (both P > 0.05). Conclusion The effect of oral solution of Huaixue Shenshu in treatment of IgA nephropathy is good.

BACKGROUND:The researches about the effect of retinoic acid on the proliferation of adipose-derived stem cells are rare, and the researches on the testosterone are mainly on the inhibition of cellaging. OBJECTIVE: To study the effects of retinoic acid and testosterone or combination on the cellcycle of adipose derived stem cells. METHODS:Adipose derived stem cells were isolated from adult female Sprague Dawley rats with 2 months age and cultured in vitro til passage 3 adipose derived stem cells, and then the 3rd passage adipose-derived stem cells were performed with adipogenic induction, osteogenic induction and surface marker identification. The cells were divided into six groups:(1) Control group;(2) 10-5 mol/L retinoic acid group;(3) Retinoic acid group;(4) 10-5 mol/L retinoic acid+testosterone group;(5) 10-6 mol/L retinoic acid+testosterone group;(6) Testosterone group. The adipose-derived stem cells in the control group were cultured with Dulbecco’s modified Eagle’s medium+10%fetal bovine serum culture medium, and the adipose-derived stem cells in the other five groups were induced with corresponding dose of retinoic acid and testosterone on the basis of control group. After cultured for 36 hours, the flow cytometry was used to detect the changes of cellcycle. RESULTS AND CONCLUSION:Compared with the control group, cellproportions in phase G 1 of 10-5 mol/L retinoic acid group and 10-6 mol/L retinoic acid group were increased significantly, and the cellproportions in phase S were decreased. Compared with control group, the cellproportion in phase G 1 of testosterone group was significantly reduced, and the cellproportion in phase S was increased. Compared with 10-5 mol/L retinoic acid group and 10-6 mol/L retinoic acid group, cellproportions in phase G 1 of 10-5 mol/L retinoic acid+testosterone group and 10-6 mol/L retinoic acid+testosterone group were reduced significantly and the cellproportions in phase S were increased. Retinoic acid can inhibit the cellcycle of adipose-derived stem cells in phase G 1 , and delay the process of the cellcycle from phase G1 to phase S;while testosterone can promote the cellcycle of adipose-derived stem cells from phase G1 to phase S;the combination induction of retinoic acid and testosterone can accelerate the process of the cellcycle of adipose-derived stem cells from phase G 1 to phase S.

n occurring after the treatment of IVM in women with PCOS are not mounting. However, the relative high rates of multiple pregnancies, low birth weight and preterm labor were increased.

OBJECTIVETo investigate whether adipose-derived stem cells (ADSCs) induced by retinoic acid (RA) in vitro express primordial germ cell marker alkaline phosphatase (ALP) and vasa.

METHODSADSCs were isolated from adult female SD rats and cultured in vitro. The third passage of ADSCs was identified by adipogenic differentiation, osteogenic differentiation and cell surface marker detection. The ADSCs were treated with 1×10(-5), 1×10(-6), or 1×10(-7) mol/L RA for 7 or 14 days, and the cellular expression of ALP was detected. vasa mRNA expression in ADSCs treated with 1×10(-5) mol/L RA for 7 days was detected using RT-PCR.

RESULTSThe OD value of ADSCs treated with 1×10(-5), 1×10(-6), or 1×10(-7) mol/L RA was 0.59∓0.04, 0.27∓0.07, and 0.15∓0.03 after a 7-day treatment, and was 0.42∓0.02, 0.34∓0.01, and 0.19∓0.02 after a 14-day treatment, respectively, demonstrating significantly enhanced ALP expression in RA-treated ADSCs compared with that in the control cells (0.07∓0.01 and 0.07∓0.01 at 7 and 14 days, respectively, P<0.01). The ADSCs showed a negative vasa mRNA expression after 1×10(-5) mol/L RA treatment for 7 days.

CONCLUSIONRA-induced ADSCs express ALP, a marker of primordial germ cells, but does not express the primordial germ cell marker vasa.
