Objective To observe the changes of serum anti-mttllerian hormone (AMH) level in women with premature ovarian fail-ure (POF) and its clinical significance. Methods Fasting serum levels of AMH in 25 POF patients were measured with enzyme-linked im-mtmosorbent assay (ELISA). Twenty healthy women matched for age and body mass index (BMI) were chosen as controls. Results The serum AMH level in POF group was (1.1±0.1) pmol/L, which was significantly lower than that of control group(P < 0.01). The serum AMH levels in 20 patients of POF group were undetectable. The other 5 patients were treated with artificial cycle at first, and then ovulated with hMG/HCG.2 patients had ovulation and 1 patient was pregnant. Conclusion The serum AMH level in POF patients was significantly decreased, and the measure for serum AMH had some significance for POF diagnosis and treatment.

Objective To determine the role of interleukin-18(IL-18) and vascular endothelial growth factor (VEGF) in the ovari-an hyperstimulation syndrome (OHSS) development. Methods Serum and follicular IL-18 and VEGF levels were measured with ELISA in 66 IVF patients, who were divided into three study groups according to OHSS risk factors on the day of ovum retrieval and whether will devel-op OHSS in future or not. 20 patients had no OHSS risk factors (normal group), 28 patients had OHSS risk factors without developing OHSS (OHSS risk group) and 18 patients had OHSS risk factors and developing OHSS in future (OHSS group). Results Serum and follicular IL-18 levels in OHSS group were significantly higher than those of other two groups(P<0.01). Serum and follicular VEGF levels in OHSS group were also significantly higher than those of other two groups(P<0.01). Conclusion Serum and follicular IL-18 and VEGF levels in OHSS group increased significantly, which suggested IL-18 and VEGF were positive correlated with OHSS development. And follicular IL-18 and VEGF levels in serum on the day of ovum retrieval have a prediction role in OHSS development.

Objective To investigate the role of Wnt signaling pathway hypofunction mediated by dephosphorylation ofβ-catenin in the impaired wound healing of type 1 diabetic rats. Methods The back skin defect wounds were produced in rats with type 1 diabetes. These rats were divided into control, diabetes, lithium chloride treatment, and epidermal growth factor ( EGF) treatment groups. The situation of back wound healing, the ratio ofβ-catenin positive cells,β-catenin, phosphorylatedβ-catenin, and vascular endothelial growth factor ( VEGF) levels were detected. Results Compared to diabetes group, the wound granulation tissue was more mature, wound healing time was shorter, and healing rate, as well as the ratio ofβ-catenin positive cells, dephosphorylatedβ-catenin, and VEGF levels, were higher in normal group, lithium chloride treatment group, and EGF treatment group ( P<0. 05 or P<0. 01). Conclusion The hypofunction of Wnt signaling pathway is involved in the process of wound healing in type 1 diabetic rats, of which the dephosphorylation ofβ-catenin is the key point. EGF may play a beneficial role in the wound healing of type 1 diabetic rat models via Wnt pathway.

Objective To study the antihypertensive efficacy and influence on the blood pressure parameters of nifedipine GITS therapy in patients with subacute cerebral infarction with essential hypertension by ambulatory blood pressure monitoring (ABPM).Methods Fifty-one cases of subacute cerebral infarction with essential hypertension were treated with nifedipine GITS for 14 days.ABPM were performed in all cases before and after treatment.The blood pressure parameters of blood pressure variability (BPV),morning blood pressure surge(MBPS),Trough/Peak(T/P),and smoothness index(SI) were analyzed.Results (1) After treatment with nifedipine GITS 30 mg/d for two weeks,the average 24-hour systolic blood pressure (SBP),day-time systolic blood pressure (dSBP),night-time systolic blood pressure (nSBP),24-hour diastolic blood pressure (DBP),day-time diastolic blood pressure (dDBP),night-time diastolic blood pressure (nDBP) significantly decreased((144.70 ± 14.89) mm Hg vs (163.10 ± 16.48) mm Hg,(145.67 ± 15.20) mm Hg vs (164.55 ±16.81) mm Hg,(140.85 ± 19.46) mm Hg vs (156.73 ±20.55) mm Hg,(81.24 ±8.88) mm Hg vs(89.49 ± 10.06) mm Hg,(81.25 ±9.40) mm Hg vs (90.18 ± 10.64) mm Hg,(81.34 ± 12.10) mm Hg vs (86.28 ±12.11) mmHg;t=11.01,11.53,5.29,8.71,7.53,2.31;P＜0.05)).(2) Defining the standard deviation(SD) of average blood pressure as the indexes of BPV,the blood pressure variability of systolic blood pressure(SBPV),day-time systolic blood pressure variability (dSBPV),night-time systolic blood pressure (nSBPV) decreased significantly ((16.52 ± 4.38) mm Hg vs (19.78 ± 6.72) mm Hg,(15.45 ± 4.71)mm Hg vs (17.88 ± 7.25)mm Hg,(14.94 ± 5.89) mm Hg vs (19.17 ± 8.27) mm Hg; t =3.38,2.19,2.99 ;P ＜0.05)) and the diastolic blood pressure didn't change.(3) There was negative correlation between smoothness index (SI) and BPV (r =-0.28 ; P ＜ 0.05).(4) The decreases of morning blood pressure surge (MBPS) of SBP was more significant after treatment ((22.65 ± 12.77) mm Hg) than that before treatment ((31.94 ±16.36) mm Hg).(5) The median of T/P ratio calculated by group methods was 0.721 for SBP and 0.676 for DBP,and it was 0.588 ± 0.360 for SBP and 0.628 ± 0.433 for DBP calculated by individual method.The medians of T/P ratio were above 0.5 by both methods.Conclusion It is of great significance to effectively control blood pressure and BPV in patients with stroke.Nifedipine GITS can constantly release medicine;it can lower the blood pressure,and significantly reduce BPV and MBPS.

Objective To assess the development,progression and change of nonmotor symptoms in patients with Parkinson' s disease and its impact on patients' quality of life.Methods Eighty-seven consecutive patients with idiopathic Parkinson' s disease were studied.Parkinsonian status was assessed at baseline and 3 years follow-up using Unified Parkinson' s Disease Rating Scale (UPDRS) part Ⅲ & Ⅳ,Nonmotor Symptoms Questionnaire (NMSQuset),Parkinson-related quality of life (PDQ) scales.Paired ttest,Chi-square test,Spearman rank order correlation and hierarchical regression of the major statistical procedures were employed.Results At 3 years follow-up,compared to baseline,the UPDRS Ⅲ score (22.21 ±11.31 vs 30.49± 11.68),UPDRS Ⅳ score(1.00±1.54 vs 2.94±3.12),NMS score (7.98±3.96 vs 12.35 ± 5.12) and PDQ score (28.11 ± 22.88 vs 36.65 ± 26.95) were significantly higher ( t =- 5.54,- 5.75,- 6.46,- 5.29,all P =0.000,respectively).The aggravation of motor and nonmotor symptoms caused the decline of quality of life.The prevalence of constipation,problem of remembenng thing,nocturia ranked tops,and depression,and anxiety were still in the middle,compared with baseline.The prevalence of pains,sweating,dribbling,sense of incomplete emptying etc were significantly increased during the follow-up,△R2 were 21.6％ and 23.4％ respectively,resulting in the deterioration of quality of life.Conclusions PD nonmotor symptoms appear from the early stage.The motor and nonmotor symptoms aggravate over time.

Objective To observe progression of motor symptoms and occurrence of motor complications in parkinsonian patients and investigate the rate of progression of motor symptoms and risk factors of motor complications.Methods One hundred and thirty patients diagnosed with PD in 2007 in Department of Neurology,Xinhua Hospital were followed up for 3 years.The Unified Parkinson' s Disease Rating Scale (UPDRS) and H-Y staging were used to assess and follow up motor symptoms and occurrence of motor complications,and analyze the rate of progression of motor symptoms and risk factors of motor complications with statistics.Results ( 1 ) Mean annual growth in H-Y staging was 2.5％,and UPDRS motor scores was 3.1％ ; the incidence of dysphagia at endpoint in patients was increased by 23.0％ compared with baseline; incidence of falls was increased by 16.7％;(2)Daily levodopa dose at endpoint ( OR =1.004,95％ CI 1.001—1.006,P =0.008 ) was independent risk factors with dyskinesia; While duration ( OR =1.637,95％ CI 1.083—2.473,P =0.019 ),levodopa treatment duration ( OR =0.698,95％ CI 0.494—0.987,P =0.042 ),daily levodopa dose at haseline ( OR =1.005,95％ CI 1.001—1.010,P =0.016) and at endpoint ( OR =1.014,95 ％ CI 1.001 —1.027,P =0.032 ) were risk factors with motor fluctuations.Conclusions As the disease progresses,motor function in parkinsonian patients gradually worsens,the incidence of swallowing difficulty and of falls is increased,and the incidence of motor complications is increased.The total exposure to levodopa in parkinsonian patients is predictor for motor complications.

Objective To derive a questionnaire to assess the risk of developing motor complications through a 3-year prospective investigation on 71 patients of Parkinson' s disease (PD) in the out clinic at our hospital.Methods Three years after the first assessment,71 PD out patients were reassessed using various scales,including Unified Parkinson Disease Rating Scale,Hoehn-Yahr grade,Mini Mental State Exam,Hamilton Depression Scale and Hamilton Anxiety Scale.Results The incidence of motor complications was 43.6％ (31/71).Logistic regression analysis showed that the prognostic factors for motor fluctuation were age of onset ≤ 54 (OR =6.4,95％ CI 1.7-24.5,P =0.006),the occurrence of swallowing difficulty (OR =3.8,95 ％ CI 1.0-14.1,P =0.04) and depression (OR =4.0,95 ％ CI 1.1-13.7,P =0.03),and the prognostic factors for dyskinesia were age of onset ≤54 (OR =48.5,95％ CI 1.9-121.0,P:0.02),the occurrence of falling (OR =64.1,95％ CI 2.9-142.2,P =0.008) and the daily levodopa dosage ＞ 600 mg(OR =17.5,95％ CI 1.1-276.2,P =0.04).Based on the regression model,the assessment questionnaire for motor complicationsincludes the followings:the questionnaire for motor fluctuations:the age of onset ≤54,2 points; the occurrence of swallowing difficulty,1 point; the occurrence of depression,1 point; the questionnaire for dyskinesia:the onset age ≤54,2 points; the occurrence of falling,3 points; daily levodopa dosage ＞ 600 mg,2 points.In all patients in this study,21.7％ (10/46) was asscssed to a total scorc of 0-1 which is associated with a low risk of motor fluctuation,8/16 had a score of 2 which is associated with intermediate risk and 8/9 got a score of 3-4 associated high risk; 10.2％ (5/49) had a score of 0-2,a low risk of dyskinesia,4/13 had a score of 3-4,a intermediate risk and 7/9 got a score of 5-7 which is associated with a high risk.Conclusions Age onset ≤54,the occurrence of swallowing difficulty,falling and depression,daily levodopa dosage ＞ 600 mg were considered to be the prognostic factors of motor complications in PD.The questionnaire may help to stratify PD patients into low-risk,medium-risk and high-risk groups for motor complications and the higher the score in the questionnaire is related to the higher risk of motor complications.

OBJECTIVE: To identify differentially expressed genes in peripheral blood mononuclear cells between patients with continuous mild-to-moderate asthma and healthy controls using mRNA microarray in order to explore the underlying signaling pathways and clarify the roles of CD4+ T cells in the pathogenesis of asthma. METHODS: Global transcriptomic profiles of the CD4+ T cells were defined by using Agilent Sure Print G3 Human GE 8×60K microarray. Enrichment pathways were analyzed with Ingenuity Pathway Analysis (IPA) software. RESULTS: Compared with controls, 805 genes were up-regulated, 192 were down-regulated in asthma patients. Among these, the expression of 38 annotated genes have varied by 4 times or more. Expression of CD300A was inversely proportional to the absolute value of eosinophils (r=-0.89, P=0.02) as well as the proportion of eosinophils (r=-0.94, P=0.004), while CSF1R was inversely proportional to PD20 (r=-0.83, P=0.04) and AQLQ (r=-0.88, P=0.02) by correlation analysis. CONCLUSION Numerous pathophysiological pathways may be involved in the pathogenesis of asthma. Above findings have provided a basis for the delineation the pathogenesis of asthma.
