Objective To investigate the changes of serum levels of sex hormone binding globulin (SHBG),free testosterone index (FTI) and insulin resistance; and to investigate the relationship among them and prevalence of gestational diabetes mellitus (GDM) and hypertensive disorder complicating pregnancy (HDP) in polycystic ovarian syndrome (PCOS) women during pregnancy. Methods Serum samples of 32 PCOS women and 32 non-PCOS women were collected during their gestational age from 12 to16 weeks.Serum levels of total testosterone,SHBG and insulin were detected.Free testosterone index (FTI) and homeostasis model assessment for insulin resistance (HOMA-IR) were calculated.Risk factors of GDM and HDP were analyzed by stepwise logistic regression.Data of two groups were compared with t test or Chi square test. Results Serum fasting insulin [(8.0±1.5) mU/L vs (7.1±1.5) mU/L,t=2.32,P＜0.05],FTI [0.96 (0.52-1.41) vs 0.61 (0.40-0.79),t=3.02,P＜0.05],HOMA-IR levels [1.53±0.32 vs 1.36±0.36,t=2.04,P＜0.05] and total testosterone [2.95 (1.61-4.40) nmol/L vs 2.15 (1.50-2.80) nmol/L,t=2.55,P＜0.05] were higher in PCOS group than in control group; and SHBG level [325 (312-355) nmol/L vs 360 (347-373) nmol/L,t=4.13,P＜0.05] was lower in PCOS group than in control group.Cesarean section rate (84％ vs 50％,x2 =8.58,P＜0.01) and HDP incidence (25％ vs 3％,x2=4.65,P＜0.05) were higher in PCOS group than in control group. SHBG level [(293 ±42) nmol/L] of PCOS women who complicated with GDM (n=6) was significantly lower than that [(333±40) nmol/L] of those who did not (n=26),t=2.22,P＜0.05.Serum total testosterone [(4.34±1.29)vs (2.49±1.44) nmol/L,t=3.23,P＜0.05] and FTI [1.42±0.52 vs 0.81±0.59,t=2.61,P＜0.05] were significantly higher in PCOS women complicated with HDP (n=8) than those of the PCOS women who did not (n=24).Stepwise logistic regression analysis showed that SHBG was the risk factor of GDM (OR=0.98,95％CI:0.96～1.00,P＜0.05); FTI was the risk factor of HDP in PCOS women (OR=5.53,95％CI:1.20～25.61,P＜0.05). Conclusions FTI and SHBG levels could be predictors for GDM and HDP in PCOS women during their pregnancies.

Objective To explore the influence of maternal free position combined with duole tools during the first labor stage on birth outcomes.Methods 600 normal pregnant women who were routinely examined in our hospital from May 2016 to December 2016 were selected.They were randomly divided into observation group and control group according to the number of prenatal date of pregnant women,each group in 300 cases.The control group was taken routine supine position in the first labor stage.The observation group used free position with duole tools during the first labor stage.The maternal first labor time,delivery mode,neonatal asphyxia,postpartum hemorrhage,maternal reproductive tract injury were observed.The maternal postpartum within 2 hours,the pain score,maternal childbirth response scale (CCB) and anxiety by comprehensive hospital anxiety and depression table (HAD) were assessed.Results The spontaneous delivery rate and tolerable pain of the observation group were 90.0％(270/300) and 73.7％ (221/300) respectively,which were higher than those of the control group [83.3％(250/300) and 62.0％ (186/300)].The maternal perineum II degree laceration and neonatal asphyxia rates of the observation group were 8.3％(25/300) and 1.7％ (5/300) respectively,which were lower than thsoe of the control group [12.3％(37/300) and 4.3％ (13/300) respectively],the differences were statistically significant(χ2=9.31,9.84,9.05,8.39,all P＜0.05).The maternal first labor time and postpartum hemorrhage of the observation group were (10.87±3.06)h and (121.60±15.11) mL,respectively,which were significantly lower than those of the control group [(11.69±2.48)h and (180.52±14.76)mL],the differences were statistically significant (t=8.92,9.74,all P＜0.05).The HAD score of the observation group was (6.04±1.95)pionts,which was lower than (8.76±1.21)points of the control group.CCB score of the observation group was (49.82±7.61)points,which was higher than (45.33±6.90)points of the control group,the differences were statistically significant (t=10.15,11.32,all P＜0.05).ConclusionTaking the free position with duole tools during maternal first labor stage can improve the natural delivery rate,tolerate pain and postpartum response ability significantly,the first labor stage significantly shortened,postpartum adverse reactions and psychological anxiety decreased.

Objective To explore the variations and prognostic factors of hyperhomocysteinaemia in ischemic cerebral apoplexy for the youth who administrated vitamin B6,vitamin B12 and folic acid at pretherapy and post-treatment.Methods One hundred and twenty cases of young patients with ischemic cerebral apoplexy in the Pinggu Hospital of Capital University from January 2003 to December 2013 as case group(intervention group,60 cases and 60 cases of non-intervention group),while 120 youth volunteers with the same period and age without neurological diseases as a control group.Both groups patients were detected for hyperhomocysteinaemia,folic acid and vitamin B12.The non-intervention group was administrated basic treatment,while the intervention group administrated vitamin B6,vitamin B12 and folic acid on this basis.The hyperhomocysteinaemia,folic acid and vitamin B12 were detected repetitively after four weeks.Results Compared with control group,the hyperhomocysteinaemia in ischemic cerebral apoplexy group for the youth had increased significantly ((10.2 ± 3.1) μmmol/L vs.(21.3 ± 4.5) μmmol/L,P ＜ 0.05).The hyperhomocysteinaemia,folic acid and vitamin B12 had no significant differences between intervention group and non-intervention group (P ＞ 0.05).After replenished vitamin B6,vitamin B12 and folic acid,the hyperhomocysteinaemia had decreased significantly ((10.5 ± 3.0) μmnol/L) in intervention group.Folic acid ((6.5±2.8)μg/L) and vitamin B12(450.2±155.6) ng/L) had increased significantly(P＜0.05).Conclusion The hyperhomocysteinaemia increased in ischemic cerebral apoplexy for the youth.It is that hyperhomocysteinaemia decreased by replenished vitamin B6,vitamin B12 and folic acid which make for prognosis in ischemic cerebral apoplexy for the youth.

Objective To assess the variations in different thyroid stimulating hormone(TSH) and free thyroxine (FT4) detection kits for evaluating thyroid function during pregnancy and to establish the corresponding normal reference ranges.Methods This study was based at the International Peace Maternity and Child Health Hospital affiliated to Shanghai Jiaotong University School of Medicine.A total of 200 pregnant women who visited the hospital between June,2011 and September,2012 were recruited in this study according to the National Academy of Clinical Biochemistry (NACB) criteria.Blood samples were sequentially collected from the women at the first (T1,9-12 weeks),second (T2,16-24 weeks) and third (T3,32-36 weeks) trimesters to determine the serum TSH and FT4 levels using four different detection kits (Siemens-C,Siemens-Ⅰ,Abott and Roche).A linear trend test was used to analyze serum TSH and FT4 levels with four different kits.A percentile range of P2.5 to P97.5 was used to establish the normal trimester-dependent reference ranges of TSH and FT4 levels for different detection kits.The Bootstrap method was used to compare the differences in the four reference ranges.Results Similar dynamic changes in TSH and FT4 levels during pregnancy were detected among the different kits (F=0.950,P=0.595; F=11.640,P=0.081,respectively).Among the four reference ranges of TSH,the Roche kit showed the most remarkable fluctuation during pregnancy,while Roche kit in the first trimester and Siemens C kit in the second and third trimesters showed larger fluctuations in reference ranges of FT4.More importantly,the reference ranges of TSH and FT4 showed significant variations among the four different kits in each trimester (TSH:T1:F=2 945.390,P ＜ 0.01; T2:F=2 826.260,P ＜ 0.01; T3:F=1 698.360,P ＜ 0.01.FT4:Tl:F=1 145.440,P ＜ 0.01; T2:F=2 260.240,P ＜ 0.01; T3:F=1 439.920,P ＜ 0.01).Conclusions TSH and FT4 measurement using four different commercial kits showed similar trimester-dependent dynamic changes.However,it is necessary to establish trimester-dependent and detection kit dependent normal reference ranges of TSH and FT4 for thyroid function evaluation for pregnant women.

Objective To analyze the recurrence risk of patients single post-stroke epilepsy. Methods Fifty-eight cases of epilepsy after stroke in Pinggu District Hospital of Beijing were enrolled in this study and their history clinical information were retrospectively collected. All patients were divided into single attack group (A group)and two or more attack group(B group). Results There were 3. 67%(58/1580)stroke patients were developed epilepsy. Among them,0. 38%(6/58)of patients were developed seizures in early stage,and 3. 29%(52/58)in late stage. Thirty-one cases occurred epilepsy once within one years in A group and 27 cases occurred epilepsy more than twice with one year in B group. Initiate epilepsy onset of 2 cases(A1)was at early stage and 29 cases(A2)at late stage in A group. Initiate epilepsy onset of 3 case(B1)was at early stage and 24 cases(B2)at late stage in B group. There was no significant difference in term of types of epilepsy between two groups(χ2 =0. 001,P﹥0. 05). The lesions site of 13 cases was located cortex and 18 cases was located in below cortex in A group,in B group,the lesions site was located in cortex of 17 cases or below cortex of 10 cases,and the difference was not significant(χ2 =2. 555,P﹥0. 05). The hemorrhagic stroke and ischemic stroke were 12 and 19 cases in A group,10 and 17 cases in B group,and there was no significant difference between two groups (χ2 =0. 017,P﹥0. 05). Rhythm of slow wave and the epileptiform discharges were 11 and 2 cases in A group, 11 and 13 cases in B group. About 51. 8% of the patients with recurrence of epilepsy had history of infection in B group. Conclusion For stroke patients,especially hemorrhagic stroke,first seizure is late-onset epilepsy cases. If the electrical activity of the brain is abnormal slow rhythm or epileptiform discharges,close to the cortex is more likely to cause epilepsy recurrence. It is supposed to giving positive antiepileptic drug treatment in the first epilepsy after stroke.

OBJECTIVETo explore the effects of different concentrations of putrescine on proliferation, migration, and apoptosis of human umbilical vein endothelial cells (HUVECs).

METHODSHUVECs were routinely cultured in vitro. The 3rd to the 5th passage of HUVECs were used in the following experiments. (1) Cells were divided into 500, 1 000, and 5 000 µg/mL putrescine groups according to the random number table (the same grouping method was used for following grouping), with 3 wells in each group, which were respectively cultured with complete culture solution containing putrescine in the corresponding concentration for 24 h. Morphology of cells was observed by inverted optical microscope. (2) Cells were divided into 0.5, 1.0, 5.0, 10.0, 50.0, 100.0, 500.0, 1 000.0 µg/mL putrescine groups, and control group, with 4 wells in each group. Cells in the putrescine groups were respectively cultured with complete culture solution containing putrescine in the corresponding concentration for 24 h, and cells in control group were cultured with complete culture solution with no additional putrescine for 24 h. Cell proliferation activity (denoted as absorption value) was measured by colorimetry. (3) Cells were divided (with one well in each group) and cultured as in experiment (2), and the migration ability was detected by transwell migration assay. (4) Cells were divided (with one flask in each group) and cultured as in experiment (2), and the cell apoptosis rate was determined by flow cytometer. Data were processed with one-way analysis of variance, Kruskal-Wallis test, and Dunnett test.

RESULTS(1) After 24-h culture, cell attachment was good in 500 µg/mL putrescine group, and no obvious change in the shape was observed; cell attachment was less in 1 000 µg/mL putrescine group and the cells were small and rounded; cells in 5 000 µg/mL putrescine group were in fragmentation without attachment. (2) The absorption values of cells in 0.5, 1.0, 5.0, 10.0, 50.0, 100.0, 500.0, 1 000.0 µg/mL putrescine groups, and control group were respectively 0.588 ± 0.055, 0.857 ± 0.031, 0.707 ± 0.031, 0.662 ± 0.023, 0.450 ± 0.019, 0.415 ± 0.014, 0.359 ± 0.020, 0.204 ± 0.030, and 0.447 ± 0.021, with statistically significant differences among them (χ(2) = 6.86, P = 0.009). The cell proliferation activity in 0.5, 1.0, 5.0, and 10.0 µg/mL putrescine groups was higher than that in control group (P < 0.05 or P < 0.01). The cell proliferation activity in 500.0 and 1 000.0 µg/mL putrescine groups was lower than that in control group (with P values below 0.01). The cell proliferation activity in 50.0 and 100.0 µg/mL putrescine groups was close to that in control group (with P values above 0.05). (3) There were statistically significant differences in the numbers of migrated cells between the putrescine groups and control group (F = 138.662, P < 0.001). The number of migrated cells was more in 1.0, 5.0, and 10.0 µg/mL putrescine groups than in control group (with P value below 0.01). The number of migrated cells was less in 500.0 and 1 000.0 µg/mL putrescine groups than in control group (with P value below 0.01). The number of migrated cells in 0.5, 50.0, and 100.0 µg/mL putrescine groups was close to that in control group (with P values above 0.05). (4) There were statistically significant differences in the apoptosis rate between the putrescine groups and control group (χ(2)=3.971, P=0.046). The cell apoptosis rate was lower in 0.5, 1.0, 5.0, and 10.0 µg/mL putrescine groups than in control group (with P values below 0.05). The cell apoptosis rate was higher in 500.0 and 1 000.0 µg/mL putrescine groups than in control group (with P values below 0.01). The cell apoptosis rates in 50.0 and 100.0 µg/mL putrescine groups were close to the cell apoptosis rate in control group (with P values above 0.05).

CONCLUSIONSLow concentration of putrescine can remarkably enhance the ability of proliferation and migration of HUVECs, while a high concentration of putrescine can obviously inhibit HUVECs proliferation and migration, and it induces apoptosis.
