OBJECTIVETo understand the neglect situation of elementary and high school students aged 6-17 years in western rural areas of China.

METHODSUsing multi-stage stratified cluster sampling method, 4 131 students were recruited from 26 rural elementary and high schools of 7 districts in Shanxi province and Chongqing from September 2012 to April 2013. The investigation was conducted based on 'The Development of Neglect Evaluation Norms and Influence Factors for Primary and Middle School Students' in rural areas of China. SAS 9.21 software was used for analyzing neglect rate and neglect degree for groups of age, sex and neglect types (including neglect of physical, emotional, medical, educational, safety and social).

RESULTSThe total neglect rate and degree were 55.50% (1 943/3 501) and 49.96 ± 9.67; the neglect rates for males and females were 56.78% (1 018/1 793) and 54.16% (925/1 708) (P = 0.119); the neglect degrees were 50.08 ± 9.31 and 49.83 ± 10.02 (P = 0.479), respectively. The girls' medical neglect rate (18.25%, 348/1 907) was significantly higher than that in boys (14.72%, 294/1 997) (P < 0.01); the boys' neglect degrees of physical, educational and social neglect (50.05 ± 10.46, 49.99 ± 10.81, 57.63 ± 14.63) were significantly higher than that in girls (49.34 ± 10.70, 49.07 ± 11.30, 56.37 ± 14.80) (P < 0.05). The total neglect rates of 6-8, 9-11, 12-14 and 15-17 groups were 44.48% (310/697), 60.40% (511/846), 60.89% (601/987) and 53.66% (521/971) (P < 0.01), and the total neglect degrees among these groups were 46.89 ± 8.57, 51.88 ± 9.25, 51.88 ± 9.25 and 51.72 ± 8.89 (P < 0.01), respectively. Except the neglect rates of medical and social neglect, significant differences were found in other three neglect rates and neglect degrees. The rates of social, emotional and safety neglect in 9-11 group were higher than that in other groups (28.39% (264/930), 26.41% (239/905), 20.35% (187/919)). The 12-14 group has the highest educational neglect rate(29.41%, 317/1 078). While the physical and emotional neglect degrees in 12-14 and 15-17 group were higher than that in other groups(12-14 group: 51.59 ± 10.02, 53.43 ± 12.02, 15-17 group: 51.96 ± 9.80, 52.61 ± 11.59). The social, safety, educational and medical neglect degrees were the highest in 6-8, 9-11, 12-14 and 15-17 group (60.91 ± 13.13, 48.29 ± 11.34, 52.43 ± 10.55, 51.15 ± 17.25), respectively. The neglect rates and neglect degrees were significantly higher in minorities(68.88% (374/543) and 52.91 ± 9.14) than those in Han population (53.04% (1 569/2 958), 49.44 ± 9.67)(P < 0.01 in both indexes); and the neglect rates and neglect degrees were significantly higher in children with siblings group (58.20% (1 504/2 584), 50.58 ± 9.54) than those the in one-child group (47.87% (439/917), 48.27 ± 9.80) (P < 0.01 in both indexes); and the neglect rates and neglect degrees were significantly higher in left-hand students (61.65% (1 101/1 786), 51.41 ± 9.51) than those in living-with-parents students(49.10% (842/1 715), 48.56 ± 9.61) (P < 0.01 in both indexes).

CONCLUSIONThe children neglect situation is serious in western rural areas, close attention from families, schools and the society is in urgent need.

OBJECTIVETo investigate the level and distribution characteristics of anemia of the minority ethnic group children in Yunnan.

METHODThe cases with anemia were surveyed from 13 336 samples of 15 minority ethnic groups and Han children in Yunnan by Taking the method of random cluster sampling.

RESULTThe prevalence of anemia among the children under 7 years of age of 15 ethnic groups of minority in Yunnan was 13.6%. There are differences among the different ethnic groups (χ(2) = 716.33, P < 0.01), the highest was 26.6% in Jingpo, the lowest was 3.5% in Bai. There were differences among the different regions, the prevalence of anemia was high in the border regions City, the highest was 23.8% in Dehong; the prevalence of anemia was low in inland cities, the lowest was 2.7% in Fugong, and was higher in border areas. The prevalence of anemia was higher in boys (13.6%) than in girls (12.1%). There were differences among the different age in the different ethnic groups (6 months to 1 years old: χ(2) = 70.52, P < 0.01; 1 - 2 years old:χ(2) = 185.86, P < 0.01; 2 - 5 years old: χ(2) = 296.12, P < 0.01; 5 - 6 years old:χ(2) = 107.11, P < 0.01; 6 - 7 years old:χ(2) = 185.02, P < 0.01), the highest was 59.0% of Deang in 1 to 2 years old children. The trend of change was that the highest prevalence was seen in 6 months to 1 year old children, the prevalence gradually declined among older children, but rose again in children 6 years of age or older.

CONCLUSIONThe prevalence of anemia was 13.6% among the children of 15 ethnic minority under 7 years of age in Yunnan. There were differences among different ethnic groups of minority in different prefectures. There were differences among different ethnic groups of different age groups, but it was highest in 6 months to 1 year old children, it declined among older children, and rose in children 6 years of age or older. The prevalence of anemia was related to the ethnic and geographic factors.

OBJECTIVETo understand the incidence of HIV infection among men who have sex with men (MSM) in China.

METHODSMeta-analysis was performed to systematically and quantitatively review all the original research papers and reports published during 2010-2015 on the incidence of HIV infection among MSM in China. Pooled incidence, pooled hazard ratios, publication bias, heterogeneity and sensitivity analysis for those studies were calculated or analyzed by using Stata 12.0 software.

RESULTSA total of 24 studies were analyzed. Pooled incidence of HIV infection among MSM in China was 5.0/100 person year; Based on HIV case report, severe epidemic areas had higher HIV incidence than other areas (4.9/100 person year vs. 3.4/100 person year). Low education level (HR = 1.61, 95% CI: 1.21-2.15), syphilis prevalence (HR = 3.22, 95% CI: 2.21-4.70), unprotected anal sex (HR = 2.92, 95% CI: 1.51-5.63), minority ethnic group (HR = 4.01, 95% CI: 1.96-8.21), commercial sex (HR = 4.11, 95% CI: 1.47-11.46) and multiple sexual partners (HR = 2.31, 95% CI: 1.60-3.34) were the risk factors for HIV incidence.

CONCLUSIONPooled incidence of HIV infection among MSM was 5.0% in China. Low education level, syphilis prevalence, unprotected anal sex, minority ethnic group, commercial sex and multiple sexual partners were the risk factors for HIV infection.

OBJECTIVETo investigate the association of MK2 gene with low density lipoprotein cholesterol (LDL-C) and tumor necrosis factor-alpha (TNF-Α) between different gender in Xinjiang Uygur population.

METHODSA total of 350 Uygur males and 595 females were recruited randomly from Hetian area. Two single nucleotide polymorphisms (44890c/t, rs 45514798) in MK2 gene were selected and genotyped by Taqman-PCR in these subjects. All subjects underwent questionnaire-based survey, physical examination, measurement of lipid profiles and plasma TNF-Α determination.

RESULTSAmong the male subjects, the concentration of total cholesterol (TC) [TT vs. CT vs. CC: (4.35±1.20) mmol/L vs. (4.69±1.34) mmol/L vs. (4.83±1.44) mmol/L, P=0.033]and TNF-Α [TT vs.CT vs.CC: (106.63±62.39) ng/dL vs. (128.44±86.15) ng/dL vs. (153.06±82.99) ng/dL, P=0.001]were significantly different in 3 genotypes of 44890c/t. However, the LDL-C levels in TT, CT, and CC genotypes of 44890c/t were not different neither in males nor in females [males: (2.64±1.16) mmol/L vs. (2.81±1.28) mmol/L vs. (3.04±1.32) mmol/L, P>0.05; females: (2.42±1.11) mmol/L vs. (2.36±0.99) mmol/L vs. (2.43±1.05) mmol/L, P>0.05]. None of the allele and genotype frequencies of 44890c/tand rs 45514798 were different between high LDL-C group and control group. Linear regression analysis indicated that body mass index (BMI) (beta=0.089) and TNF-Α (beta=0.092) were significantly associated with LDL-C levels in males (P<0.05), while the age, BMI, and waist/hip ratio with LDL-C levels in females (P<0.05).

CONCLUSIONThe nucleotide polymorphisms (44890c/t and rs 45514798) in MK2 gene may not be associated with LDL-C in both males and females in the Uygur population in Hetian, Xinjiang.

BACKGROUND/AIMS: Uninsured individuals have lower rates of screening colonoscopy (SC), and little is known regarding the pathology results obtained when they undergo colonoscopies. Since 2004, we have participated in a program that offers SC to uninsured New Yorkers; herein, we report our findings. METHODS: Uninsured, average-risk patients who were at least 50 years of age underwent SC at our institution between April 2004 and June 2011. We analyzed polyp pathology, location, size, incidence of adenomas, and incidence of adenomas with advanced pathology (AAP) with respect to ethnicity, gender, and age. RESULTS: Out of 493 referrals, 222 patients completed the colonoscopies. Polyps were identified in 21.2% of all patients; 14% had adenomas, and 4.5% had AAP. The rates of adenomas among African-Americans, Hispanics, and Whites were 24.3%, 12.1%, and 11.6%, respectively, and the corresponding rates of AAP were 10.8%, 3.5%, and 2.3%. Differences in the polyp type, location, and AAP did not reach statistical significance with respect to ethnicity or gender. Patients aged 60 and older were found to have a higher rate of advanced adenomas compared with younger patients (8.6% vs 2.6%, p=0.047). CONCLUSIONS: Further efforts to fund screening colonoscopies for uninsured individuals will likely result in the identification of advanced lesions of the colon before they progress to colorectal cancer.
