Objective: To investigate the drinking status and associated factors in adults in China. Methods: Based on the 2010-2012 China National Nutrition and Health Survey (CNNHS), a total of 135 824 participants aged ≥18 were included in this cross-sectional analysis. Multivariable logistic regression model was used to investigate the associated factors for drinking status. Results: The overall drinking rate was 30.5% in Chinese adults, 53.8% in men, and 12.2% in women. The excessive drinking rate was 14.0% in men and 1.1% in women. The daily drinking rate was 25.7% in men and 10.9% in women. Men mainly consumed multi-type wines, but women preferred beer. The overall harmful drinking rate was 7.1%. The excessive drinking rate, daily drinking rate, and harmful drinking rate increased first but then declined with age. All the four rates were positively related with physical activity. Conclusions: The drinking rate, excessive drinking rate, daily drinking rate and harmful drinking rate were high in adults in China. Drinking status was associated with age, sex, marital status, education level, smoking status and physical activity.

Objective: To explore the relationship between abnormal expression of fragile histidine triad (FHIT) gene and methyl-CpG-binding protein 2 (MeCP2) as well as their interaction on cervical cancerization. Methods: A total of 73 patients with cervical squamous cell carcinoma (SCC), 113 patients with cervical intraepithelial neoplasia (CIN Ⅰ, n=45; CINⅡ/Ⅲ, n=68) and 60 women with normal cervix (NC) were included in the study. Real time PCR and Western blot were performed to detect the expression levels of mRNA and protein about FHIT and MeCP2, respectively. The methylation status of FHIT gene CpG island was tested by methylation-specifc PCR (MSP). Kruskal-Wallis H test, χ(2) test, trend χ(2) test and Spearman correlation analysis were conducted with software SPSS 20.0. The interaction was evaluated by generalized multifactor dimensionality reduction (GMDR) model. Results: With the deterioration of cervical lesion, the methylation rates of FHIT gene CpG island (χ(2)=18.64, P<0.001; trend χ(2)=18.08, P<0.001) increased gradually, while the expression levels of FHIT mRNA (H=27.32, P<0.001; trend χ(2)=12.65, P<0.001) and protein (H=47.10, P<0.001; trend χ(2)=29.79, P<0.001) decreased gradually. There was a negative correlation between the methylation rates of FHIT gene CpG island and the expression level of FHIT protein (r=-0.226, P<0.001). The levels of MeCP2 mRNA (H=26.19, P<0.001; trend χ(2)=11.81, P=0.001) and protein (H=69.02, P<0.001; trend χ(2)=47.44, P<0.001) increased gradually with the aggravation of cervical lesions. There was a positive correlation between the expression level of MeCP2 protein and the FHIT mRNA Ct ratio (r=0.254, P<0.001). Expression of proteins were negatively correlated between MeCP2 and FHIT (r=-0.213, P=0.001). The results analyzed by GMDR model showed that there were interactions among high MeCP2 protein expression, the CpG island methylation of FHIT and mRNA and protein expression in CINⅡ/Ⅲ group, and among high MeCP2 mRNA and protein expression, the CpG island methylation of FHIT and low mRNA and protein expression in SCC group. Conclusion: High expression of MeCP2 mRNA and protein, the CpG island methylation and low mRNA and protein expression of FHIT could increase the risk of cervical carcinogenesis, and there might be a synergistic effect on cervical carcinogenesis.

Objective: To evaluate the effects of polycyclic aromatic hydrocarbons (PAHs) and high risk human papillomavirus (HR-HPV) infection and their interaction on the progression of cervical intraepithelial neoplasia. Methods: A total of 486 patients, including 208 women with normal cervix (NC), 154 patients with low-grade cervical intraepithelial neoplasm (CINⅠ), 124 patients with high-grade cervical intraepithelial neoplasm (CINⅡ/Ⅲ), were selected from the cervical lesions cohort from June to December, 2014. HR-HPV was detected by using flow-through hybridization technology and the urine concentration of 1-hydroxypyrene (1-OHP) was detected with high performance liquid chromatography. By using software SPSS 22.0, the χ(2) test, trend χ(2) test, Kruskal-Wallis H test, Nemenyi rank test and Spearman rank correlation analysis were performed. And the interaction effects were evaluated by additive model. Results: The HR-HPV infection rates in NC, CINⅠ and CINⅡ/Ⅲ groups were 27.9%, 37.0% and 58.9%, respectively. The urine concentrations of 1-OHP (μmol/molCr) were 0.07±0.09, 0.11±0.10 and 0.17±0.15, respectively. With increasing severity of the cervical lesions, the HR-HPV infection rate gradually increased (trend χ(2)=29.89, P<0.001) and the high exposure rate of PAHs gradually increased (trend χ(2)=27.94, P<0.001). HR-HPV infection was positively correlated with 1-OHP exposure (r=0.680, P<0.001). There was a positive additive interaction between HPV infection and PAHs exposure in CIN Ⅱ/Ⅲ group, but it was not found in CIN Ⅰ group. Conclusion: Both HR-HPV infection and high exposure of PAHs might increase the risk of cervical intraepithelial neoplasm, and might have a synergistic effect on the progression of high-grade cervical intraepithelial neoplasia.

Objective: To investigate the histopathological and immunohistochemical characteristics of benign apocrine cystic papillary hyperplasia of the breast with loss of myoepithelial cell layer. Methods: The clinical data, histopathological features and immunohistochemical profile of patients with benign apocrine cystic papillary hyperplasia of breast with loss of myoepithelial cell layer from January 2016 to December 2021 were examined, in which six patients were identified. Results: All six patients were female, aged 36-61 years (median 46 years), who presented with a breast mass; three cases were from the left breast and three cases were from the right breast. Microscopic examination of all cases showed breast hyperplasia with apocrine cysts, accompanied by different degrees of micropapillary and papillary hyperplasia of apocrine cells. One case was associated with lobular carcinoma in situ, and one case was associated with apocrine ductal carcinoma in situ with intraductal dissemination in adenosis. Immunohistochemical staining of CK5/6, p63, SMA, SMMHC, Calponin and CD10 showed complete absence of myoepithelial cell layer surrounding ducts in apocrine cystic papillary hyperplasia. Conclusions: The myoepithelial cells of apocrine cystic papillary hyperplasia of the breast may undergo abnormal changes and may even be completely lost. The diagnosis should be comprehensively considered along with cytomorphological and histological features to avoid overdiagnosis.

Objective: To assess the prevalence of blood donation and associated factors in men who have sex with men (MSM) in China. Methods: Our observational study was conducted between January and August, 2017 in 3 cities: Guangzhou, Shenzhen and Wuxi. Eligible participants were MSM (≥18 years old) who had either ≥2 male sex partners or unprotected anal sex with casual partners, or had been diagnosed with STI in the past 6 months. A self-completed tablet-based questionnaire was used to collect the information about MSM's socio-demographic characteristics, sexual behaviors and blood donation history. Results: A total of 603 MSM were enrolled in our study, including 302 in Guangzhou, 152 in Shenzhen and 149 in Wuxi, with a mean age of 27.9 years (SD=7.8). Overall, 29.2% (176/603) of the MSM reported a history of blood donation, and 33.1% (100/302)in Guangzhou, 27.6% (42/152) in Shenzhen and 22.8% (34/149) in Wuxi, the differences were not significant (χ(2)=6.421, P=0.093). Multivariate logistic regression analysis indicated that MSM had ever tested for HIV for ≥2 times in the past 12 months (vs. MSM tested for HIV one time, aOR=1.49, 95%CI: 1.08-2.19) or who had ever used gay dating app (vs. MSM who not used gay dating app, aOR=2.13, 95%CI: 1.12-4.44) were more likely to donate blood. Conclusions: Blood donation was common in MSM in China. Health education about blood donation in MSM should be strengthened to ensure the blood safety.

Objective: To investigate the clinicopathological features of glomuvenous malformation (GVM). Methods: Thirty-one cases of GVM diagnosed at the Henan Provincial People's Hospital from January 2011 to December 2021 were collected. Their clinical and pathological features were analyzed. The expression of relevant markers was examined using immunohistochemistry. The patients were also followed up. Results: There were 16 males and 15 females in this study, with an average age of 11 years (range, 1-52 years). The locations of the disease included 13 cases in the limbs (8 cases in the upper limbs, 5 cases in the lower limbs), 9 cases in the trunks, and 9 cases in the foot (toes or subungual area). Twenty-seven of the cases were solitary and 4 were multifocal. The lesions were characterized by blue-purple papules or plaques on the skin surface, which grew slowly. The lumps became larger and appeared to be conspicuous. Microscopically, GVM mainly involved the dermis and subcutaneous tissue, with an overall ill-defined border. There were scattered or clustered irregular dilated vein-like lumens, with thin walls and various sizes. A single or multiple layers of relatively uniform cubic/glomus cells were present at the abnormal wall, with scattered small nests of the glomus cells. The endothelial cells in the wall of abnormal lumen were flat or absent. Immunohistochemistry showed that glomus cells strongly expressed SMA, h-caldesmon, and collagen IV. Malformed vascular endothelial cells expressed CD31, CD34 and ERG. No postoperative recurrence was found in the 12 cases. Conclusions: GVM is an uncommon type of simple venous malformation in the superficial soft tissue and different from the classical glomus tumor. Morphologically, one or more layers of glomus cells grow around the dilated venous malformation-like lumen, which can be combined with common venous malformations.

Objective: To explore the relationship between male sexual function and daily exposure to bisphenol A (BPA) at a reproductive center in Taiyuan. Methods: Male patients who were seeking treatment of infertility due to problems caused by either of the spouse were selected from the Shanxi reproductive center between September 2014 and April 2015. Information on general characteristics, sexual function and fasting venous blood samples were collected. Total scores of sexual function were evaluated by Delphi expert scoring method. Levels of serum BPA were measured by high-performance liquid chromatography. Data was analyzed by Spearman rank correlation, rank sum test, multivariate logistic regression analysis and χ(2) trend test. Relationship between BPA and sexual function was presented as OR and corresponding 95%CI. Results: Among the 353 participants, 45.0% was defined as sexual dysfunction with low sexual desire (47.3%) as the major reason. BPA was detected in all the 353 patients, with a range of concentration as 0.38-21.93 ng/ml and an average as 5.79 ng/ml. Results from the Spearman rank correlation analysis revealed significant negative correlations between serum BPA and sexual function, sexual desire, erectile ability and ejaculation intensity, while serum BPA was positively correlated with premature ejaculation. According to the four percentile of BPA concentration (ng/ml), the subjects were divided into four groups. Compared with the low concentration group (0.38-3.79 ng/ml), the risk of sexual dysfunction significantly increased in the groups with higher BPA levels. Particularly, in the highest BPA group (8.68-21.93 ng/ml), more obvious effects were seen on sexual dysfunction (OR=1.55, 95%CI:1.00-3.23), reduced sexual desire (OR=4.75, 95%CI: 2.44-9.22), reduced erection ability (OR=2.40, 95%CI: 1.18-4.88), reduced ejaculation intensity (OR=2.53, 95%CI: 1.25-5.16) and premature ejaculation (OR=1.95, 95%CI: 1.02-3.72). Conclusion: Low sexual desire appeared as the main type of male sexual dysfunction, the exposure to higher levels of BPA in daily life might lead to male sexual dysfunction.
