Objective: To investigate the socio-demographic and cultural factors of spousal violence(SV) in order to provide systematic basis of SV prevention.Methods: By using multistage stratified sampling methods,3087 households were selected from Chenzhou city in Hunan Province.After screening,384 households had SV.Among them 80 households were randomly selected for study,in which 80 perpetrators were not in the domestic violence(DV) group.For the non-DV group,after matching of family’s structure,96 households without violence behavior were selected,in which after matching of gender and age with perpetrators,96 normal controls were enrolled.Results: The ratio of male perpetrators(81.3%) was more than female(18.7%),but female(81.3%) was more than male(19%) victims(P

Objective:To investigate the psychosocial characteristics of the perpetrators and the victims of spouse violence (SV).Methods:80 families with a history of SV were randomly selected from communities, and their psychosocial characteristics were compared with control group of 96 non-SV families matched for family structure. A self-designed SV questionnaire, the self-report Symptom Checklist-90 (SCL-90), Eysenck's Personality Questionnaire (EPQ), Trait Coping Style and Questionnaire (TCSQ) were used in this cross-sectional survey.Results:65 husbands and 15 wives were identified as perpetrators, correspondingly 65 wives and 15 husbands as victims. The total score and factors scores of SCL-90, EPQ-N score, and scores of subjective social support, objective support and total supports were higher in perpetrators than their counterparts in control group. Negative coping style and EPQ-P score were respectively higher and lower in perpetrators than victims of SV (29.6?8.3/29.5?7.4,t=2.127, P

Seven cases of typical salpingian diverticulum were identified by hysterosalpinography (HSG). The differentiation diagnosis of the disease was discussed. HSG is believed to be the method of choice for the diagnosis of this disease.

The B Phycoerythrin(B PE) could both be separated after crude phycobiliproteins from Porphyridium cruentum were precipitated in ammonium sulphate and dialyzed,then chromatographed on a hydroxylapatite (HA) Column and a Sephadex G 100 column respectively.The purity of B PE separated by two methods was 4.92 and 3.78 (A 545 nm/A 280 nm) respectively.When the purified B PE was electrophoresed under polyacryiamide gradient gel electrophoresis condition,only one band was observed.The B PE possessed an absorption maximum at 545nm and a room fluoresence emission at 574.5nm.

OBJECTIVETo elucidate the effect of hydroxysafflor yellow A ( HYSA) on the proliferation of vascular smooth muscle cells (VSMCs) and the related mechanism.

METHODSVSMCs derived from SD rats were treated with DMEC culture medium (Control), 10 ng/ml PDGF (PDGF group), pretreatment with HYSA at different doses (1, 5, 10, 20, 40, 60 µmol/L) for 24 h then cotreatment with PDGF. After 24 h, MTT assay, Western blot and immunohistochemical staining were performed to evaluate the inhibitory effects of HYSA on VSMCs proliferation.

RESULTSHYSA inhibited PDGF induced VSMCs proliferation in a dose-dependent manner, dowregulated proliferating cell nuclear antigen (PCNA) expression and blocked PDGF activated PDGFR-MEK-ERK1/2 signaling pathway.

CONCLUSIONSHYSA inhibits VSMCs proliferation possibly via downregulating the expression of PCNA and blocking MEK-ERK1/2 signal transduction in VSMCs.

Aim To investigate the role of phospho-lipase C epsilon 1 ( PLCE1 ) in modulating the apoptot-ic mechanism in esophageal cancer ( Eca ) cells. Methods Eca cell lines, OE33 and CP-C cells were cultured to assess the expression of PLCE1 . siRNA suppress expression of PLCE1 . The expression of PLCE1 and p53 was evaluated by quantitative real time PCR and Western blot. Methylation analyses of p53 were performed by bisulfite conversion of genomic DNA. Apoptosis was assessed by flow cytometry. Results OE33 and CP-C cells expressed high levels of PLCE1 . Knockdown of PLCE1 markedly increased the expression and hypomethylation of p53 , and in-creased the frequency of apoptosis. Conclusion PLCE1 suppresses apoptosis of Eca cells via promoting p53 promoter methylation and inhibiting expression of p53 .

OBJECTIVE To investigate antibiotic resistance and the prevalence of serotype of Streptococcus pneumoniae in Wuhan.METHODS Totally 152 strains of S.pneumoniae were collected to test the MICs of various antibiotics by agar dilution method according to the approved standard of NCCLS.Serotyping of S.pneumoniae was performed by using quelling reaction.RESULTS Among 152 strains of S.pneumoniae,65(42.76%) strains were resistant to penicillin(MIC≥0.12mg/L).94.08%,50.66%,41.45% and 11.18% of S.pneumoniae were resistant against the first(cefalexin),second(cefaclor) and third(cefaxime and ceftriaxone) generation of cephalosporins respectively.The resistance rates to other antibiotic agents,such as erythromycin,tetracycline,trimethoprim/sulfamethoxazole and chloramphenicol,were 84.21%,88.82%,89.47% and 18.42%,respectively.Strains that were resistant to levofloxacin and moxifloxacin were found both for 1.32%.Twenty serotypes were involved in 152 strains. The prevalent serotypes were 19(25.66%),23(19.08%),6(13.82%),15(7.24%)and 14(4.61%).Eight strains were remained for unable to serotype.All penicillin-resistant S.pneumoniae was included in serotypes 6,19 and 23.CONCLUSIONS The antibiotic resistance of S.pneumoniae is serious in Wuhan.Most of them are multi-resistant strains.Except for fluoroquinolones,ceftriaxone and chloramphenicol, most antibiotic agents have lost there activities against S.pneumoniae.The prevalent serotypes,especially of the multi-resistant strains,were 19,23 and 6.Pneumococcal polyvalent vaccine can well cover these serotypes.

Objective To explore the association between impulsively aggressive behavior and rs6922753 single nucleotide polymorphism of glutamate receptor 6 (GluR6) gene in Xinjiang Uygur and Han patients with bipolar disorder.Methods The techniques of polymerase chain reaction (PCR) and DNA sequencing technique were conducted to detect rs6922753 single nucleotide polymorphism of GluR6 gene in 240 patients with bipolar disorder.The association between the polymorphisms and impulsively aggressive behavior was analyzed with SPSS 17.0 software.Results No statistical difference was observed between the impulsively aggressive behavior group and the no impulsively aggressive behavior group of Xinjiang Han and Uygur patients with bipolar disorder in the genotype and allele frequencies for the investigated rs6922753 polymorphisms (P ＞ 0.05).Conclusions No association was found between the impulsively aggressive behavior and rs6922753 single nucleotide polymorphism of GluR6 gene in Xinjiang Uygur and Han patients with bipolar disorder.

Aim To investigate the activation of prote-ase-activated receptor 2 ( PAR2 ) in regulation of the expression of epidermal growth factor receptor ( EGFR) and apoptosis of lung cancer ( LC) cells. Methods LC cells A549 and its EGFR-silenced counterpart were incubated in the medium added with tryptase. Quanti-tative RT-PCR and Western blotting were used to de-tect the expression of EGFR in A 5 4 9 cells . The apop-tosis and Bax/Bcl-xL of cells were also recorded. Re-sults Treating A549 cells with tryptase in the culture for 48 hrs resulted in a marked increase in the expres-sion of EGFR in A549 cells. Marked decreases in a tryptase dose-dependent manner in apoptotic A549 cells were detected in the presence of tryptase. Expo-sure to tryptase markedly decreased the levels of Bax and increased the levels of Bcl-xL in A549 cells, which were not shown in EGFR-deficient A549 cells. Conclusion Tryptase can increase the expression of EGFR in LC cell line, A549 cells, which protects A549 cells from apoptosis, increases Bcl-xL, and sup-presses Bax in A549 cells.
