Objective To study the correlation of artery stiffness with left ventricular remodeling and cardiac function in coronary heart disease (CHD) patients .Methods Four hundred and eighty patients were divided into CHD group (n=373) and non-CHD group(n=107)according to their coronary angiography .Patients in CHD group were further divided into normal left ventricular re-modeling group (n=139) and abnormal left ventricular remodeling group (n=243) .Their brachi-al-ankle pulse wave velocity (BaPWV ) was measured .The patients underwent echocardiography and 42 patients in CHD group received Doppler tissue imaging .Results The BaPWV was signifi-cantly higher in CHD group than in non-CHD group (P<0 .01) and in abnormal left ventricular remodeling group than in normal left ventricular remodeling group (1689 ± 305 cm/s vs 1508 ± 280 cm/s ,P< 0 .05) .The BaPWV was positively related with the IVST ,PWT ,RWT ,LVMI ,E/Ea and negatively related with the LVEF ,Ea ,Ea/Aa in CHD group (P<0 .05 ,P<0 .01) .Partial cor-relation analysis showed that the BaPWV was significantly related with the IVST ,PWT ,RWT , LVMI ,LVEF ,Ea ,Ea/Aa and E/Ea when the effect of hypertension ,etc ,was excluded (P<0.01) .Multivariate regression analysis demonstrated that the BaPWV was an independent factor for LVMI and LVEF .Conclusion BaPWV is an independent factor for left ventricular remodeling and cardiac function in CHD patients .

OBJECTIVETo study the effect of ginsenoside Rb1 on GSKbeta/IDE signal transduction pathway and Abeta protein secretion in hippocampal neurons of high glucose-treated rats.

METHODHippocampal neurons of 24 h-old newly born SD rats were primarily cultured, inoculated in culture medium under different conditions, and then divided into the normal group, the high glucose group, the LiCl group and the Rb1 group. After being cultured for 72 h, the expressions of their phosphorylated GSK3beta, total GSK3beta and IDE protein were detected by Western blotting analysis. The mRNA expressions of GSK3beta and IDE were determined by RT-PCR. The ELISA assay was used to detect the secretion of Abeta protein in cell supernatant.

RESULTCompared with the normal group, the high glucose group showed increase in the p/tGSK3beta protein ratio and the secretion of Abeta protein and decrease in IDE protein and mRNA (P < 0.05). Compared with the high glucose group, both Rb1 and LiCl groups showed decrease in the p/tGSK3beta protein ratio and the expression of Abeta protein and increase in IDE protein and mRNA expression (P < 0.05). Compared with the LiCl group, the Rb1 group showed no significant difference in the expressions of p/tGSK3beta protein, IDE protein, mRNA and Abeta protein expression. In addition, the GSK3beta mRNA expression of the four groups had no significant difference.

CONCLUSIONGinsenoside Rb1 may reduce the secretion of Abeta protein in hippocampal neurons by reducing the phosphorylation of GSK3beta, down-regulating the ratio of pGSK3beta/GSK3beta and upregulating the expression of IDE.

Objective To assess the distribution of vaginal microflora in healthy women and investigate their cognition of lower reproductive tract infection-related knowledge as well as personal hygiene habits and character of behavior in seeking medical treatment. Methods Total of 1660 healthy women who had physical check-ups at the Medical Center of Renji Hospital were selected and received gynecologic examination, as well as routine examination, pH examination and bacterial culture of the vaginal discharge. In addition, 860 of them were randomly selected for questionnaire survey, in which reproductive tract infection -related knowledge and personal hygiene habits as well as behavior in seeking medical treatment were involved. Results Among the 1660 eensused women, vaginal average pH was 4. 16±0.21. The positive rate of Candida in vaginal discharge routine examination was 3.86% (64/1660), which was lower than that in aerobes culture 7.71% (128/1660). Candida alhicans was the most populous species 78.9% (101/128) ,followed by 7.8% (10/128) and 7.0% (9/128) for the Candida glabrata and Candida krusei respectively. The most populous species of vaginal microflora were hemolytic streptococcus A (63.80%, 1059/1660), Staphylococcus epidermidis (14.28%, 237/1660), and Enterococcus faecalis (D) group ( 11.44%, 190/1660). The questionnaire survey showed that 88.4% (760/860) of 860 women took active treatment when feeling unwell, 92.1% (792/860) of them had good hygiene practices, and only 21.2% (182/860) had the habit of vaginal douching. In addition, 50.0% (430/860) of them had the desire to obtain reproductive health knowledge through out-patient consultation. Conclusions Vulvovaginal Candida disease ranks the first in all types of vaginitis, among which, Candida albicans is the most populous species followed by the Candida glabrata and Candida krusei. Hemolytic streptococcus A and Staphylococcus epidermidis are the most common species of vaginal mieroflora in healthy women. The censused women have high awareness of reproductive health care and pay mueh attention to common gynecologic diseases such as lower reproductive tract infection. Nevertheless, we should strengthen the public education of reproductive health-related knowledge.

Objective To investigate the correlated pathogenetic factors and vaginal local immunity in vulvovaginal candidiasis (VVC). Methods A case control study was conducted to compare VVC group (60 cases) with normal group (60 cases). All of the women filled up the specific questionnaires. Routine examination, pH test and bacterial culture were done on the vaginal discharge. Cytokines of the vaginal lavage were measured by enzyme linked immanosorbent assay. Results (1) Outcomes of the questionnaires: there was no significant difference between the two groups in educational background,knowledge of gynecologic infection, history of gynecologic infection, hygienic habit, sex life, or use of medicine (P >0. 05). The incidence of chronic cervicitis in normal group (43%, 26/60) was higher than in VVC group (22%, 13/60; P <0.05). (2) There was no difference in vaginal pH between the two groups ( P > 0. 05 ). (3) Detection rate of candida albicans by vaginal discharge routine examination was 72% (43/60). (4) The concentrations of interleukin (IL) 2, and IL-4 in vaginal lavage did not show significant difference between the two groups ( P > 0. 05 ), but the concentrations of human defensin 5,human beta-defensin (HBD) 1, and HBD2 in WC group [(0.94±0.44) mg/L, (3.1±0.4) μg/L,(10±6) μg/L] were higher than normal group (P < 0.05). Conclusions VVC is a common vulvovaginitis. There is no significant correlation between the incidence of VVC and educational background,knowledge of gynecologic infection, history of gynecologic infection, hygienic habit, sex life, or use of medicine in the child-bearing period. Human defensin may be closely correlated with the pathogenesis of VVC.
