Objective To learn the awareness rate of HIV/Syphilis knowledge,condom usage,group behaviors and the infections among men who have sex with men (MSM)in Zhuhai and provide scientific foundation for preparing control measures.Methods The internet community was used for calling MSM to join the research.A MSM survey questionnaire was used to collect messages in the place of HIV Voluntary Counseling & Testing(VCT).The blood samples were collected to proceed biological detection.Re-sults Total 247 MSMs were tested,positive rates of HIV,TP specific antibody and non-specific antibody were 8.10% (20/247), 13.36%(33/247)and 10.72% (24/247).The separation between cognition and behavior was common existed in such population. HIV/syphilis infection rates were significant different between MSMs who had multiple sexual partners and those who did not. Conclusion Because the high risk behaviors are commonly existed among MSM in Zhuhai,the prevalence rates of HIV/Syphilis in them are high.It is necessary promote the screening of HIV/Syphilis,enhance the health education of disease control and block the transmission to develop a safe awareness and behaviors in MSM.

Objective To observe the distributions of epidermal growth factor receptor(EGFR),transforming growth factor ?(TGF ? 1,? 2,? 3)and thyroid transcription factor 1(TTF 1)in developing lungs,and to discuss their functions and relationships each other. Methods The expression of EGFR and TGF ? was examined in mouse fetal lungs by immunohistochemistry.TIGER image analysiser was used in TTF 1 quantitative study. Results 1.In the early developmental phase,EGFR localized in the epithelium of airway surface,TTF 1 was expressed predominantly in the nuclei of distal lung buds and TGF ? was expressed in the bronchioles with localization patterns.2.At the late developmental phase,the positive reactions of EGFR and TTF 1 were mainly detected in alveolar cells.TGF ? expressed in mesenchymal at high levels.3 The average optical density(A A )of TTF 1 in the distal epithelial cells increased gradually during the development,while their volume(VOL)and volume integrated optical density(VI A )all decreased.Conclusion\ The functions of EGFR,TGF ? and TTF 1 might be respectively different at different developmental stages.They not only stimulate the process of branching morphogenesis,but also modulate epithelial maturation and differentiation.\;[

Objective Scutellarin (SCU), a Chinese traditional medicine, has a protective effect against ischemia-reperfusion (IR) induced myocardial injury, but it is not yet clear whether SCU acts against vascular endothelial IR injury via extracellular signal-regulated kinase 1/2 (ERK1/2).The aim of this study was to explore the effect of SCU on hypoxia-reoxygenation (HR)-induced injury to human cardiac microvascular endothelial cells (HCMECs) and its influence on the ERK1/2 signaling pathway.Methods HCMECs were subjected to normal culture and divided into a normal control, a DMSO, an SCU 1 μmol/L, and an SCU 10 μmol/L group.The model of HR injury was established by exposing the HCMECs to 12-h hypoxia and 12-h reoxygenation after treated with DMSO or SCU at 1 and 10 μmol/L for 2 hours.Then, the survival rate of the HCMECs was detected by MTT and trypan blue staining, the concentration of malondialdehyde (MDA) in the cells measured, and the expressions of the p-ERK1/2, ERK2 and GAPDH proteins determined by Western blot.Results SCU at 1 and 10 μmol/L significantly increased the survival rate of the normally cultured HCMECs ([110.40±2.34] and [122.00±1.25] ％) as compared with that of the normal control (100％) (P<0.05), while HR injury markedly decreased the vitality of the HCMECs ([68.00±4.06] ％) in comparison with that of the blank control (100％) (P<0.05).The survival rate of the HCMECs was remarkably higher in the HR+SCU 1 μmol/L and HR+SCU 10 μmol/L groups than in the HR model group ([90.53±3.67] and [92.04±2.32] ％) (P<0.05), and so was their vitality in the SCU 10 μmol/L group than in the normal control ([96.78±2.01] vs [90.06±1.85] ％, P<0.01), while their survival rate was significantly lower in the HR model than in the blank control ([73.72±4.91] vs [91.83±2.34] ％, P<0.01) and remarkably higher in the SCU 10 μmol/L ([87.59±2.64] ％) than in the HR model group (P<0.05).The MDA concentration in the HCMECs was markedly increased in the HR model and HR+DMSO groups as compared with the blank control (P<0.01), but decreased in the HR+SCU 1 μmol/L and HR+SCU 10 μmol/L groups in comparison with the HR model group (P<0.05).The expression of the p-ERK1/2 protein was significantly down-regulated in the HR model group as compared with the blank control (P<0.01), but up-regulated in the HR+SCU 10 μmol/L group in comparison with the HR model (P<0.01).Conclusion HR injury reduces the vitality of HCMECs, increases the MDA concentration, and down-regulates the expression of the p-ERK1/2 protein in HCMECs, while SCU acts against ischemia-reperfusion injury to HCMECs by increasing ERK phosphorylation.

Objective To construct the serine protease gene(sprE)mutant and to study the pathogenicity of sprE gene of Enterococcus faecalis.Methods Recombinant suicide vector pCQ001 of Enterococcus faecalis with pTX4577,was constructed.Then,created isogenic sprE-deficient mu- tant(*sprE)by allelic replacement was constructed.Moreover,the growth ability and the virulence of the mutant were compared with those of the wide type in vitro and in vivo respectively.A mouse peritonitis model and a rabbit endocarditis model were utilized in the study.Results The *sprE was selected by kanamycin and identified by polymerase chain reaction(PCR),pulsed field gel electropho- resis(PFGE)and Southern blot.The evidences showed that the sprE gene had a major role in helping bacteria to resist the elevated temperature and oxidative stress.The virulence of mutant decreased af- ter sprE gene was knocked out.Conclusions The *sprE of Enterococcus faecalis is constructed suc- cessfully,sprE gene is important in the pathogenesis of Enterococcus faecalis,which probably is a major virulence factor of Enterococcus faecali.

AIM: To systemically evaluate the clinical efficacy and safety of intraocular implants for vitreous retinal surgery.METHODS: We performed a comprehensive search for studies reporting vitreous surgery with intraocular implants randomized controlled and a retrospective controlled clinical trials from China Hownet ( CNKI ), Wanfang database, and VIP literature database. Studies obtained from those database were filtered according to the criteria, and data were retrieved from eligible studies for further analysis. Then we performed a meta-analysis to evaluate the efficacy and safety of intraocular implants using comprehensive Meta - analysis software version 2 (Biostat, Englewood, NJ).
RESULTS: In total 36 studies were recruited for our Meta - analysis, including 5 092 cases. Meta analysis showed: 1) regarding the efficacy of repairing the retinal detachment, silicone oil was a better intraocular implants than C3 F8(OR= 1. 76; 95% CI: 1. 19-2. 60, P = 0. 0047) and SF6( OR = 4. 68; 95% CI: 1. 48 - 14. 81, P = 0. 0087); 2) regarding the risk of postoperative cataract, silicone oil showed significant higher risk than BBS (OR = 3. 24; 95%CI: 2. 10-4. 99, P= 1. 09 e-7), and C3 F8(OR= 3. 03; 95% CI:1. 50 - 6. 10, P = 0. 0019 ); 3 ) regarding the risk of postoperative intraocular pressure, silicone oil showed significant higher risk than BBS (OR= 6. 74; 95% CI: 3. 38-13. 41, P= 5. 67 e-08), and C3 F8 also showed a higher risk than BBS (OR= 4. 79; 95% CI: 2. 37-9. 68, P = 1. 29 e-05). In addition, silicone oil showed significant lower risk as compared with heavy silicone oil (OR= 0. 16; 95% CI: 0. 08-0. 53, P= 0. 0026).
CONCLUSION: The intraocular implants for the treatment of retinal detachment in vitreous retinal surgery are mainly divided into two major categories, liquid and gas implants. The silicone oil, a major liquid implant, shows higher efficacy in terms of treating retinal detachment than the gas implants. However, the silicone oil is associated with a higher risk of postoperative cataract and intraocular pressure as compared with gas implants.

Objective To compare the pathogenesis of coronary heart disease (CHD) with heart_blood stagnation syndrome (HBSS) due to Qi deficiency and Qi stagnation. Methods Indices such as endothelin,NO,TXB 2 ,6-Keto-PGF 1? ,blood rheology,platelet aggregation rate,atrial natriuretic factor,high_frequency electrocardiogram and cardiac function were observed. Results The changes of the above indices in CHD with HBSS due to Qi stagnation (Group A)were smaller than those due to Qi deficiency(Group B). Conclusion Qi stagnation is the primary stage of CHS with HBSS,the pathological changes being mild;Qi deficiency is the advanced stage,the pathological changes being severe.

[ABSTRACT]OBJECTIVETo assess the upper airway and related structures in different patterns of the upper airway obstruction on cine magnetic resonance (CMR) imaging in patients with obstructive sleep apnea hypopnea syndrome (OSAHS).METHODSCMR images of upper airway were obtained in 30 male patients with severe OSAHS during waking state and natural sleep. The midsagittal plane images were obtained. Patients were classified into 3 groups based on the upper airway obstruction patterns at apnea events and the reference data of the upper airway were measured.RESULTSDuring natural sleep, the diameter of retropalatal region, retroglossal region, retroepiglottic region and the length of suprahyoid muscles were significantly shorter than those during waking state (P<0.01). The maximum angle between the suprahyoid muscles and the apex of the tongue during natural sleep was significantly larger than that during waking state (P<0.01). During wakefulness, there was a significantly difference in the diameter of retropalatal region among 3 obstruction patterns (P<0.01). During natural sleep, there were statistical difference in the diameter of retropalatal region and the upper tongue, the angle between the hard palate and soft palate, the maximum angle between the suprahyoid muscles and the apex of the tongue, and their change values among 3 obstruction patterns (P<0.05). CONCLUSIONThe measurements of the upper airway and related structures on CMR imaging in OSAHS patients could provide useful information in assessing upper airway.

OBJECTIVETo evaluate the efficacy and safety of Jinying Capsule (JC) in treating pelvic inflammatory disease patients with accumulated damp-heat syndrome (ADHS).

METHODSTotally 328 patients were recruited in a prospective, positive drug parallel controlled, and multi-center clinical trial. Of them 213 patients in the treatment group took JC (0.5 g per capsule), 4 capsules each time, 3 times per day, while 115 patients in the control group took Kangfuyan Capsule (KC, 0.4 g per capsule), 3 capsules each time, twice per day. The course of treatment was 4 weeks for all. Scores of Chinese medical syndromes, visual analogue scale (VAS) of the lower abdominal pain, and European quality of life-five dimension scale (EQ-5D) were observed before treatment and after 4 weeks of treatment.

RESULTSThere were 204 patients in the treatment group and 109 in the control group who completed this trial. The total effective rate of Chinese medical syndrome was 89.71% (183/204 cases) in the treatment group and 76.15% (83/109 cases) in the control group (P < 0.01). Compared with before treatment in the same group, EQ-5D scores increased, and VAS scores of the lower abdominal pain decreased in the two groups after treatment. EQ-5D scores was 0.857 ± 0.157 in the treatment group, obviously higher than that in the control group (0.753 ± 0.126, P < 0.05). VAS scores of the lower abdominal pain was 2.14 ± 1.23 in the treatment group, lower than that in the control group (2.33 ± 1.24), but with no statistical difference between the two groups (P > 0.05). No adverse reaction occurred in the two groups.

CONCLUSIONJC was superior to KC in improving Chinese medical syndrome and quality of life of pelvic inflammatory disease patients with accumulated damp-heat syndrome.
