RÉSUMÉ
The participants in this study were 20-49 years old rural childbearing age people who received the National Free Preconception Health Examination Project (NFPHEP) in Yunnan Province during 2013 to 2019. The proportion of ABO and RhD blood groups among different ethnic groups and different areas were calculated. The proportion of 2 748 131 participants with blood group A phenotype was highest (32.60%), followed by O (30.60%), B (27.33%) and AB (9.47%). In the RhD blood system, the proportion of the RhD positivity (RhD+) and RhD negativity (RhD-) group were 99.29% and 0.71% respectively. The proportions blood groups were significantly different among ethnic groups and areas (all P<0.001). Among 18 ethnic groups with more than 3 000 participants, Yao (42.75%), Bouyei (40.58%) and Dai (40.37%) ethnic groups had higher proportion of blood group O phenotype than other ethnic groups. Wa ethnic groups had highest proportion of the A (40.15%) and AB phenotypes (11.23%). Miao ethnic group (34.70%) and Lahu ethnic group (34.42%) had higher proportion of blood group B phenotype than other ethnic groups. Wa ethnic group had the highest proportion of RhD-group (1.88%). In all 16 prefectures of Yunnan, the proportion of blood group O phenotype was highest in Xishuangbanna Dai Autonomous Prefecture (40.27%). Baoshan city (36.39%), Lincang city (36.22%) and Dali Bai autonomous prefecture (36.06%) had higher proportion of blood group A phenotype than other regions. Diqing Tibetan Autonomous Prefecture (30.83%) and Qujing city (30.48%) had higher proportion of blood group B phenotype than other areas, while Zhaotong city had a highest proportion of blood group AB phenotype (11.19%). The proportion of RhD-group was highest in Honghe hani and Yi nationality autonomous prefecture(1.37%). The A RhD+(39.36%), A RhD-(0.78%), AB RhD+(11.03%), AB RhD-(0.20%) and O RhD-(0.48%) blood groups were higher proportion in Wa ethnic group than in other ethnic groups (P<0.001).

A study was conducted on rural women of childbearing age aged 20-49 who underwent the National Free Preconception Health Examination Project (NFPHEP)in Yunnan Province from 2013 to 2019. Descriptive analysis was conducted to determine the negative rate of IgG antibodies against the rubella virus and its differences among various socio-demographic characteristics. Among the 1 511 203 study subjects, the negative rate of IgG antibodies against the rubella virus was 24.36%. Only 2.64% of the population had received rubella virus vaccine. The negative rate of IgG antibodies among rural childbearing-age women in the preconception period in Yunnan Province decreased with age and educational level (Ptrend<0.001). The negative rate of IgG antibodies in ethnic minority women of childbearing age in the preconception period (25.19%) was higher than that of Han women (23.88%). Among the 22 ethnic groups with over 1 000 participants, the negative rates of IgG antibodies in women of childbearing age from the Blang (32.85%), Bouyei (31.03%), Zhuang (31.01%), and Miao (30.70%) ethnic groups were higher than those of women from other ethnic groups. Among the 16 states (cities) in Yunnan Province, the negative rate of IgG antibodies in pregnant women of childbearing age in Wenshan Zhuang and Miao Autonomous Prefecture (38.06%) and Lincang City (32.63%) was higher than that in other states (cities). The negative rate of serum IgG antibodies in women who reported having received rubella virus vaccine (18.60%) was lower than that in other non-vaccinated populations (24.52%). The proportion of rural women of childbearing age in Yunnan Province who were susceptible to the rubella virus before pregnancy was still high. It is necessary to promote rubella vaccination among people susceptible to rubella, especially pregnant women, to prevent rubella virus infection and reduce the incidence rate and disease burden of rubella people.

@#Objective To explore the characteristics of blink reflex (BR) and brainstem auditory evoked potential (BAEP) in patients with consciousness disorder and the role of BR and BAEP in the evaluation of brain stem function. Methods From January to December, 2015, 31 patients with consciousness disorder were examined with BAEP, BR and Glasgow Coma Scale (GCS), and the outcome was record-ed one month after examination. Results BAEP and BR were positively related with GCS score (r≥0.562, P<0.05) and outcome (χ2=9.644, P<0.01). Conclusion Both BR and BAEP can reflect the brain stem function and respective pathway. Their combination could provide ob-jective basis for prognosis evaluation.

Objective To investigate the expression levels of miR-494 in breast cancer tissues and cell lines,and its correlations with the clinical stages,metastasis and prognosis of breast cancer.Methods The expression levels of miR--494 in 5 breast cancer cell lines,including MDA-MB-231,MDA-MB-453,HCC-1937,MDA-MB-468 and MCF-7,and normal breast cell line HBL-100,were detected by quantitative real-time polymerase chain reaction (qRT-PCR).The breast cancer tissues and normal adjacent tissues from 54 patients with breast cancer were collected,and their expression levels of miR-494 were determined by qRT-PCR.Then,the correlations of miR-494 levels with clinical stages,metastasis and prognosis of breast cancer were analyzed.Results The expression levels of miR-494 in MDA-MB-231,MDA-MB-453,HCC-1937,MDA-MB-468 and MCF-7 cells were significantly lower than that in HBL-100 cells (t =212.9,37.73,27.53,10.61 and 19.46,respectively,and all P <0.05).The expression levels of miR-494 in breast cancer tissues were also significantly lower than that in normal adjacent tissues (t =5.80,P < 0.01).Moreover,the expression of miR-494 was significantly related to the clinical stage (x2 =17.41,P <0.05),tumor grade (x2 =5.33,P <0.05),C-erbB-2 expression (x2 =9.83,P < 0.05) and the percentage of Ki-67 positive cells ((2 =6.13,P < 0.05) of breast cancer.Conclusion The expression levels of miR-494 are significantly dowrregulated in breast cancer tissues and cell lines,and related to the clinical stage,metastasis and prognosis of breast cancer,indicating that miR-494 may serve as a new biomarker for the diagnosis and prognosis of breast cancer.
RÉSUMÉ
The aim of the present study was to accurately evaluate the association of Sox2 expression with the survival of patients with digestive tract cancers. Relevant literatures were identified by comprehensively searching databases including the Pubmed, Embase, CBMdisc, and Wanfang (up to October 2014). A meta-analysis was performed to clarify the association between Sox2 expression and overall survival or clinicopathological parameters of patients with digestive tract cancers (esophageal, gastric, and colorectal cancers). The results showed a significant association between high Sox2 expression and poor overall survival in patients with digestive tract carcinomas (HR=1.55, 95% CI=1.04-2.31), especially for patients with esophageal cancer (HR=2.04, 95%CI=1.30-3.22), colorectal cancer (HR=1.40, 95% CI=1.04-1.89), and digestive tract adenocarcinoma (HR=1.80, 95% CI=1.12-2.89), for Europeans (HR=1.98, 95% CI=1.44-2.71) or patients who did not receive neoadjuvant treatment (HR=1.73, 95% CI=1.10-2.72). Furthermore, Sox2 over-expression was highly correlated with vascular invasion (OR=1.86, 95% CI=1.25-2.77) and poor differentiation (OR=1.88, 95% CI=1.14-3.08), especially in esophageal and colorectal cancers. In conclusion, Sox2 expression may serve as a novel prognostic factor for patients with digestive tract cancers. Over-expression of Sox2 that is correlated with vascular invasion and poor differentiation suggests poor outcomes of patients with digestive tract cancers.
