Purpose:To study the expression of Survivin,P21 WAF1/CIP1 and CyclinD1 proteins in cervical carcinoma and to investigate their relation to recurrence of early stage cervical cancer of the uterus.Methods:Using streptavidin-biotin peroxidase (sp) method,we examined the protein expression of Survivin, P21 WAF1/CIP1 and Cyclin D1 in 55 cervical carcinomas (45 cervical squamous carcinomas and 10 cervical adenocarcinomas ) and 10 normal cervical tissues.Results:① The positive rates of Survivin,Cyclin D1,P21 WAF1/CIP1 were 0,10.0%,20.0% in normal cervical tissue,and 68.9%,51.1%,57,8% in cervical squamous carcinomas,and 60.0%,90.0%,80.0% in cerrical adenocarcinomas respectively. There were significant differences in the positive results of Survivin,CyclinD1,P21 WAF1/CIP1 between normal cervical tissue and cervical cancer ( P 0.05).③The coexpression of Survivin with P21 WAF1/CIP1 or CyclinD1 were both associated with higher tumor grade( P

Objective To compare the effectiveness and safety of Foley catheter(FC)and vaginal prostaglandin E2 suppository(PGE2,Propess)for cervical ripening and labor induction in fullterm pregnant women with unfavorable cervix.Methods A prospective randomized controlled trial was conducted.Women with a term or post-term,live,singleton fetus in cephalic presentation,intact membranes,Bishop score＜6,not in labor,medically indicated for labor induction from June 2009 to December 2009 in Drum Tower Hospital of Nanjing University Medical School were randomly divided into two groups:FC group(n=64)and Propess group(n=62).In FC group,a 16-F Foley catheter was inserted into patient's cervical canal; once past the internal os,the balloon was inflated with 80 ml saline.Intravenous oxytocin was initiated after the balloon was spontaneously extruded from the cervix or after 24 hours.In Propess group,vaginal Propess was used.x2 or Fisher's exact test and t test were used to compare the outcomes,delivery mode and induction success rate between the two groups.Results There were no significant differences in gestational weeks,Bishop score,indication of induction,improvement of Bishop score,success rate of induction,rate of vaginal delivery,total duration of labor and volume of postpartum hemorrhage between the two groups(P ＞ 0.05,respectively).Propess group had a higher rate of vaginal birth within 24 hours[56.5％(35/62)vs 28.1％(18/64),t=10.37,P＜0.05],a higher risk for excessively frequent and hard uterine contraction[17.7％(11/62)vs 0.0％(0/64),P＜0.05]and lower incidence of oxytocin induction/augmentation during labor[21.0％(13/62)vs 87.5％(56/64),x2 =56.27,P＜0.05]than those of FC group.There were no differences in neonatal Apgar score,meconium staining and neonatal birth weight between the two groups.Puerperal infection occured in neither group.Conclusions Under strict control of indication and aseptic manipulation,Foley catheter was as effective and safe as Propess for cervical ripening with lower risk of excessive uterine activity.It is suggested that Foley catheter could be used for cervical ripening,especially in patients with economic difficulty.

Objective To investigate the pregnancy outcomes of in vitro fertilization (IVF) and embryo transfer (ET) in infertile women with polycystic ovarian syndrome (PCOS).Methods From August 2005 to June 2011,200 IVF-ET cycles performed in women with polycystic ovarian syndrome in Shengjing Hospital and Shenyang 204 Hospital were enrolled in this retrospective study,matched with 400 IVF-ET cycles in infertile women with fallopian tube factors as control group.The incidence of abortion,gestational diabetes mellitus (GDM),hypertensive disorders in pregnancy,preterm birth,small for gestational age infant(SGA),large for gestational age infant (LGA),neonatal asphyxia,neonatal death and deformity was compared between two groups.Results The incidence of spontaneous abortion was 26.0％ (52/200) in PCOS group,which was significantly higher than 10.2％ (41/400) in control group (P ＜ 0.05).The incidence of GDM,hypertensive disorders in pregnancy,preterm birth,cesarean section in PCOS group was 23.6％ (35/148),16.2％ (24/148),17.6％ (26/148),83.1％ (123/148),which were significantly higher than 4.2％ (15/359),6.1％ (22/359),7.8％ (28/359),73.8％ (265/359) in control group (P ＜0.05).The incidence of SGA,LGA,neonatal asphyxia,neonatal death and deformity did not show remarkable difference between two groups,which were 2.7％ (4/148),4.7％ (7/148),5.4％ (8/148),0 in PCOS group and 1.4％ (5/359),2.2％ (8/359),2.8％ (10/359),0 in control group (P ＞0.05).Conclusion IVF-ET is an effective treatment for infertile women with PCOS,however,the incidence of spontaneous aborcion,GDM,hypertensive disorders in pregnancy,preterm birth,cesarean section in PCOS patients was increased.

Objective:To observe changes of serum uric acid (UA)level and red cell distribution Width (RDW)in se-nile men With chronic heart failure (CHF),and explore their correlation With cardiac function.Methods:A total of 60 senile male CHF patients Were enrolled,including 28 cases of NYHA cardiac function class Ⅱ and 32 cases of NYHA class Ⅲ-Ⅳ.Another 30 cases With normal cardiac functionWere regarded as normal control group.Levels of UA,RDW and high sensitive C reactive protein (hsCRP)Were measured,and patients received color-coded Doppler echocardiography,change of every index Was compared among patients With different cardiac function class.Results:Compared With normal control group,there Were significant rise in serum levels of UA [(318.2± 54.3)μmol/L vs.(434.7±72.7)μmol/L],RDW [(13.84±0.60)% vs.(15.79±0.74)%]and hsCRP [(2.23 ±0.56)mg/L vs.(6.35±2.34)mg/L]in CHF group,and they significantly rose alongWith cardiac function class aggravated,P <0.01 all;there Were significant decrease in transmitral early diastolic peak floW velocity/transmitral late diastolic peak floWvelocity [E/A,(1.02±0.36)vs.(0.75±0.13)]and left ventricular ejection fraction [LVEF,(59±9)% vs.(49±9)%]in CHF group,and they significantly reduced along With cardiac function aggravated, P <0.01 both;in CHF group;UA,RDW and hsCRPWere negatively correlatedWith E/A and LVEF (r =-0.391~-0.731,P <0.05 all);RDW Was positively correlated With hsCRP (r =0.491,P <0.05).Conclusion: Serum uric acid and red cell distributionWidth are correlated to cardiac function in senile male patients,Which can help to judge the severity of heart failure and guide clinical treatment.

Objective: To explore the correlation among serum prealbumin (PAB) level, red cell distribution width (RDW) and cardiac function in advanced aged male patients with chronic heart failure (CHF). Methods: Research objects included 60 patients with heart failure（28 cases with NYHA class Ⅱ and 32 cases with NYHA class Ⅲ-Ⅳ, heart failure group）and 30 cases with normal cardiac function admitted in the same period（normal control group）. Serum PAB, hemoglobin (Hb) concentration and RDW, red blood cell (RBC) count were measured. Patients all received echocardiography examination. Changes of all indexes were compared among patients with different cardiac function class. Results: ① Compared with normal control group, there was significant decrease in serum PAB level [(252±49) mg/L vs. (185±36) mg/L] and significant increase in RDW [(13.84±0.60) % vs. (15.79±1.33) %] in heart failure group, and compared with class Ⅱ group, there was significant decrease in serum level of PAB and significant increase in RDW in class Ⅲ-Ⅳ group, P<0.01 all; ② Compared with normal control group, there were significant decrease in E/A [(1.02±0.36) vs. (0.75±0.18)] and left ventricular ejection fraction [LVEF, (59±9) % vs. (49±11) %] in heart failure group, and the worse cardiac function was, the lower these two indexes were, P<0.01 all; ③ Pearson linear correlation regression analysis indicated that PAB was positively correlated with E/A and LVEF (r=0.451, P<0.05; r=0.596, P<0.05), and RDW was negatively correlated with E/A and LVEF (r=-0.391, P<0.05; r=-0.574, P<0.05) in heart failure group. Conclusion: Prealbumin and red cell distribution width are closely correlated to cardiac function class in advanced aged male patients. Both of them can indirectly reflect cardiac function in advanced aged patients with chronic heart failure.

Objective: To evaluate the false positive rate and false negative rate of the Chinese version of the 12-item General Health Questionnaire (GHQ-12) and the related factors in the epidemiological survey of mental ill-nesses in Zhejiang Province. Method: A total of 15000 subjects were randomly selected from the province-wide using multi-stage stratified cluster randomization. Analyses for this paper were made in the quality control sample,10% of the total 15000 subjects (1510 subjects) in which the Chinese version of Structured Clinical Interview for DSM-Ⅳ Axis Ⅰ Disorders (SCID) was used as a golden criterion, and a cutoff score of the GHQ-12 was set to ≥ 3 to define GHQ-12 cases. Results: Totally 1449 subjects (96.0%) completed both the GHQ-12 and the SCID. Adjusted for sampling effects, the false positive and negative rates of the GHQ-12 were respective 14.6% and7.8%. Adjusted for other considered correlates and sampling effects, the adjusted odds ratios (AORs) of GHQ-12 false positive with living in less economically developed urban areas (urban type Ⅱ), with self-reportedly poor physical health, with having ever sought help because of mental problems and with being currently married/co-habited were respective 2.23 (95% CI:1.24～4.01), 2.36(1.36～4.10), 1.53 (1.10～2.14) and 0.51 (0.30～0.86) while AORs of GHQ-12 false negative with being aged 35～49 year group and living in less econom-ically developed rural areas (rural type Ⅲ) were respective 2.59 (1.18～5.67) and 2.72 (1.21～6.14). Conclusion:Factors related to the GHQ-12 false positive and negative are different. The cutoff scores of the GHQ-12 should be used based on the characteristics of subjects during identifying or screening mental illnesses.

To discover an efficient strategy for the conversion of the antibacterial activity of fluoroquinolones into the antitumor activity, the three series of C-3 s-triazole-based derivatives including sulfide ketones (6a-6g), thiosemicarbazones (7a-7g) and fused heterocyclic thiazolotriazoles (8a-8g) were synthesized from ciprofloxacin (1), respectively. The structures were characterized by elemental analysis and spectral data. The antitumor activity was tested against three tumor cell lines (Hep-3B, Capan-1 and HL60) using the MTT assay. The three types of compounds all exhibited stronger anti-proliferative activities than ciprofloxacin in the test. The order of their activities was in compounds 7>8>6, and the order of selectivity against cancer cell lines was Capan-1, Hep-3B and HL60. Meanwhile, the SAR revealed that some compounds with electron-drawing group substituted such as fluoro- and nitro-phenyl compounds (6f, 7f, 8f) and (6g, 7g, 8g) displayed more significant activity than the control compounds, especially the IC50 values of thiosemicarbazone compounds 7f and 7g against Capan-1 was comparable to doxorubicin. Thus, a five-membered triazole as the C-3 bioisostere modified with the functionalized side-chain of sulfide-ketone thiosemicarbazone warrants special attention and further investigation.

To discover novel antitumor rhodanine unsaturated ketones, a series of fluoroquinolone (rhodanine α, β-unsaturated ketone) amine derivatives (5a-5r) were designed and synthesized with fluoroquinolone amide scaffold as a carrier. The structures of eighteen title compounds were characterized by elemental analysis, 1H NMR and MS. The in vitro anti-proliferative activity against Hep-3B, Capan-1 and HL60 cells was evaluated by MTT assay. The results showed that the title compounds not only had more significant anti-proliferative activity against three tested cancer cell lines than that of the parent ciprofloxacin 1, but also exhibited the highest activity against Capan-1 cells. The SAR revealed that some compounds carrying aromatic heterocyclic rings or phenyl attached to an electron-withdrawing carboxyl or sulfonamide substituent were comparable to or better than comparison doxorubicin against Capan-1 cells. As such, it suggests that fluoroquinolone (rhodanine α, β-unsaturated ketone) amines are promising leads for the development of novel antitumor fluoroquinolones or rhodanine analogues.

To search for fluoroquinolones(FQs)with antitumor activity;the C-3 carboxylic acid group of peflox-acin (1)was replaced by fused heterocyclic core;and twelve novel thiazolo[3;2-b][1;2;4]triazole heterocycles(6a-6l)were designed and synthesized.The structures of target compounds were characterized by elemental anal-ysis and spectral data.The results of the in vitro antiproliferative effect on SMMC-7721;L1210 and HL60 cell lines showed that the title compounds exhibited more significant antitumor activity than both of the pefloxacin and the corresponding opening-ring intermediates(5 a-5 l).Among them;the target compounds which possess a ben-zene ring bearing a hydroxyl group (6e)or a fluorine atom (6j)exhibited more potent antiproliferative effect on SMMC-7721 cells than other compounds.Therefore;the antitumor fluoroquinolones can be designed by replacing the C-3 carboxylic acid group of fluoroquinolones with the thiazolo[3;2-b][1;2;4]triazole moiety.

A total of 60 samples were collected from 35 swimming pools in Beijing, China, and the presence of Cryptosporidium and Giardia were investigated. The results showed that 16.7% and 15.0% of samples were positive for Cryptosporidium oocyst and Giardia cysts, respectively, with a mean concentration of 0.30 oocysts/10 L and 0.27 cysts/10 L. The oocysts and cysts were found to have higher rates of occurrence in August than in May. Genotyping confirmed the presence of Cryptosporidium hominis, C. parvum, and Giardia assemblages A and B, all of which were associated with human infections. The predominant species/assemblages were C. hominis and Giardia assemblage A. Analyses of the relationships between parasite oocysts/cysts, indicator bacteria, and physical-chemical parameters revealed that there was no correlation between 2 parasites and fecal bacterial indicators, whilst there was a significant correlation between protozoa and urea concentration, which indicates that urea concentration rather than fecal bacterial indicators might be an appropriate index for chlorine-resistant protozoa in swimming pools. This study provides useful information to improve the safety of swimming pool water and deduce the risk of protozoan infections.
