Objective To evaluation the comprehensive acquired immunodeficiency syndrome (AIDS) intervention program conducting in men who have sex with men (MSM) population living in Inner Mongolia Autonomous region. Methods A comprehensive intervention program was carried out among MSM groups in Hohhot and Baotou City. Seven hundred and six and 767 MSM were enrolled for investigation through the snowball method during May 2008 and May to June 2009, respectively.At the same time, 5 mL intravenous blood sample was collected from each subject for human immunodeficiency virus (HIV) detection and intervention effect evaluation. Data were analyzed by x2test. Results After intervention, the awareness rate of HIV/AIDS knowledge increased from 70.7%(499/706) to 81.7%(627/767) (x2 =25. 004, P＜0.01 ). The rate of consistent condom use in the last six months increased from 38.0%(254/668) to 45.3% (346/764) (x2=8. 269, P＜0. 05). The percentage of subjects who had more than 5 different male sexual partner during the last 6 months significantly decreased from 42.8% to 24.6% (x2 = 55. 348, P＜0.01). The median number of sexual partners in MSM decreased from 3 in 2008 to 2 in 2009. The HIV infection rate was 1.7 % in both 2008 and 2009. Conclusion The comprehensive intervention program among MSM population shows positive influence after one year implementation, which is helpful for increasing HIV/AIDS awareness and safe sex behavior in this population.

Objective To explore the influence of hypoxia on cystathionine gamma lyase (CSE) gene expr ession of rat cultured pulmonary artery smooth muscle cells (PASMCs) and the mod ulatory effect of hydrogen sulfide on PASMCs proliferation.Methods Rat′s cultured PASMCs were randomly divided into contr ol group,NaHS group,hypoxia group and hypoxia +NaHS group. Each group contains 6 wells of cells. Hypoxic challenge was performed with oxygen concentr ation≤1%. The cell proliferation rate was measured by 3H-thymidine i ncorporation into DNA of the PASMCs. The expression of CSE mRNA was measured by quantitative competitive reverse-transcription polymerase chain reaction (RT-PCR ).Results For the PASMCs in hypoxia group, the amount of CSE mRN A was down-regulated about 67% (P

OBJECTIVETo determine the exact location of the opening of the ejaculatory duct in men and provide some basic anatomical evidence for seminal vesiculoscopy and the treatment of ejaculatory duct obstruction.

METHODSWe performed ureterocystoscopy for 21 male patients aged 26 - 47 years with hematuria (n = 12), hematospermia (n = 2), glandular cystitis (n = 6), and anejaculation after radical resection of rectal carcinoma (n = 1), and meanwhile, with the consent of the patients, massaged the prostate and ejaculatory duct and observed the outlet of the expelled fluid. Under the microscope, we described the fluid samples with sperm as the expulsion from the ejaculatory duct.

RESULTSUreterocystoscopy showed that the exact anatomical sites of the expulsion of prostatic fluid and semen in the patients were the side and lower side of the prostatic utricle opening above the verumontanum and the ventral side of the verumontanum. Quantities of sperm were found in the expulsion fluid of 13 of the patients, and no expulsion, including semen, was seen from the prostatic utricle opening.

CONCLUSIONAnatomically, the ejaculatory duct openings of males are located at the two sides of the verumontanum adjacent to the opening of the prostatic utricle, rather than in the prostatic utricle above the verumontanum.

Objective]The aim of this study was to investigate the level of serum C3,C4 and HDL-C in patients with coronary heart disease and the correlation between C3,C4 and HDL-C in patients with coronary heart disease.[Methods]We collected 251 cases of patient diagnosed with coronary artery disease by coronary angiography in Sun Yat-sen Memorial Hospital ,Sun Yat-Sen University from 2015-12 to 2016-07 and collected over our Boji Medical Center healthy people in 214 cases. These patients were divided into acute coronary syndrome group with 180 cases and stable coronary heart disease group with 71 cases. Each test results was adopted from clinical laboratory of Sun Yat-Sen Memorial Hospital ,Sun Yat-Sen University.[Results]Compared with the healthy control ,the difference of serum C3,C4 and HDL-C from acute coronary syndrome group and stable coronary heart disease group,was statistically significant(P<0.05). However,in patients with acute coronary syndrome and stable coronary artery disease groups,there was no significant correlation(P > 0.05)between C3,C4 and HDL-C. In healthy group,complement C3 negatively correlated with HDL-C,the difference was statistically significant(P<0.05).[Conclusions]In patients with coronary heart disease, the level of C3 and C4 increased,while the level of HDL-C decreased ,and inflammation may affect the relevance judgments between complement and HDL-C.

OBJECTIVETo provide fundamental information for its exploiting. Aralia echinocaulis by the resource and identification study on.

METHODResource survey and various identification were carried out.

RESULTThe county level distribution and ecological environment of A. echinocaulis were initially observed. It mainly distributed in the mountainous areas of the Yangtze River basin and the south, and was usually used as folk drug. This study also displayed its morphological, microscopic and chemophysical identification features.

CONCLUSIONThe morphological features of original plant and crude drug, and the anatomical and chemophysical characteristics of A. echinocaulis are of identification value, and the species are also of greater development and utilization potentiality, but the resource does not support the sustainable utilization. Therefore, artificial propagation is apparently crucial to its exploitation.

Cinobufacini is an aqueous extract of Bufo bufo gargarizans Cantor dried skin, which has been widely used for cancer therapy in China. So far, its active components are still not very clear. In previous reports, bufadienolides with low-concentration were usually studied because of their anticancer effects. However, the high polarity constituents in cinobufacini are less investigated. The present study found that more than 50% contents of cinobufacini were water-soluble peptides. Then, in vitro anticancer experiments were carried out, including human stomach cancer cell lines BGC823 and MCG803, human colon cancer cell lines DLD-1 and HT-29, and human pancreatic cancer cell line MIAPACA-2. The IC50 for these cell lines model were ranged from 25-123 microgmL(-1). The results indicated that these peptides showed similar activity with cinobufacini injection. As a conclusion, this study provides a new and further understanding of anticancer components in cinobufacini injection.

OBJECTIVETo investigate the associations between periodontal diseases, presence of Porphyromonas gingivalis (P. gingivalis), serum levels of pro-inflammatory mediators and preterm low birth weight (PLBW).

METHODS60 women (30 PLBW and 30 healthy women), were recruited after postpartum within 3 days in this case-control study. Periodontal measurements including plaque index (PI), bleeding index (BI), probing pocket depth (PD) and clinical attachment loss (CAL) were assessed. The subgingival plaque was collected before periodontal examination and analysed by polymerase chain reaction (PCR) for the presence of the 16S rRNA gene specific to P. gingivalis, while the venous and umbilical cord blood specimens collected were determined by enzyme-linked immunosorbent assay (ELISA).

RESULTSThe PLBW cases had a poorer oral conditions and the presence of P. gingivalis was found in a higher proportion in the PLBW than the healthy pregnant (56.7% vs. 30.0%, P < 0.05). Both of the presence of periodontitis and P. gingivalis have been found to be associated weakly with a shorter gestational age and a lower birth weight (P < 0.05). The levels of IL-1beta, IL-6 and prostaglandin-E2 (PGE2) in both of the blood samples showed higer levels between the PLBW and normal groups (P < 0.01). The IL-1beta and PGE2 levels in maternal serum were higher with a severe periodontal disease in the PLBW group (P < 0.01).

CONCLUSIONThere may be a possible link between periodontal diseases and PLBW.
