目的 了解越秀区助产机构医务人员对艾滋病母婴阻断知识及患者相关权益知识掌握情况,为更好地贯彻落实消除艾滋病母婴传播工作提供下一步工作策略和措施依据。方法 于2022年7月—8月,对广州市越秀区5家助产机构妇产科、保健科和医务科的医务人员进行艾滋病母婴阻断知识政策及HIV感染孕产妇相关权益知识的问卷调查。结果 465名医务人员对个别艾滋病母婴阻断政策了解不足,包括“人类免疫缺陷病毒（HIV）感染孕产妇到定点医疗机构终止妊娠或住院分娩时可以获得一定的减免”（知晓率79.78%）、“HIV感染孕产妇的宝宝可以免费领取一定数量的奶粉”（知晓率66.88%）;医务人员对HIV感染孕产妇的生育相关权益认识严重不足,对HIV感染孕产妇生育权益认识正确的仅有45.59%。临床护士群体对上述艾滋病母婴阻断政策及HIV感染孕产妇相关权益的知晓率低于临床医生及其他医务人员,组间比较差异有统计学意义（P<0.05）。结论 越秀区助产机构医务人员对艾滋病母婴阻断知识有一定的了解,但掌握不够完整、全面,对HIV感染患者的生育权认识严重不足,应进一步加强对助产机构医务人员、尤其是护士群体关于艾滋病母婴阻断政策知识及患者相关权益的培训,以更好地贯彻落实消除艾滋病母婴传播工作,保障HIV感染患者的权益。

Objective To understand the knowledge of medical staff of midwifery institutions in Yuexiu District about AIDS prevention of mother-to-children transmission（PMTCT）and patients' rights and interests,in order to provide the basis for the following work strategy and measures for better implementation of the elimination of mother-to-child transmission of HIV．Methods From July to August in 2022,a questionnaire survey about knowledge and policies of AIDS PMTCT and rights of HIV infected pregnant women was conducted among the medical staff of obstetrics and gynecology department,health care department and medical department in five midwifery institutions in Yuexiu District of Guangzhou City．Results A total of 465 medical workers had insufficient understanding of some policies on PMTCT of AIDS,including HIV-infected pregnant women can obtain certain fee waiver when they go to designated medical institutions to terminate pregnancy or hospitalized deliver（awareness rate of 79.78%）,HIV-infected pregnant women's babies can receive a certain amount of free milk powder（awareness rate of 66.88%）．There was a serious lack of awareness of reproductive rights of HIV-infected pregnant women among medical staff,and only 45.59% of them had correct understanding．The awareness rate of the PMTCT and the rights and interests of HIV-infected pregnant women among clinical nurses was significantly lower than that among clinicians and other medical staff．Conclusions The medical staff of midwifery institutions in Yuexiu District have some knowledge about the PMTCT of AIDS,but their knowledge is not complete and comprehensive,and their understanding of the reproductive rights of HIV-infected patients is seriously inadequate,so it is necessary to further strengthen the training of medical staff in midwifery institutions,especially nurses,on the policy knowledge of PMTCT of AIDS and the related rights and interests of patients,in order to better implement the elimination of mother-to-child transmission of AIDS and protect the rights and interests of infected patients．

Objective To understand the characteristics of Rh-negative red blood cells (RBC) supply, improve the management of storage and guarantee the safety of blood transfusion. The collection and supply of Rh-negative RBC in Guangzhou city was retrospectively analyzed. Methods The amount of Rh-negative RBC collection and supply, the distribution of ABO blood type and the consumption of blood by different hospitals in Guangzhou Blood Center from 2011 to 2017 were statistically analyzed. Results During 2011-2017, 11 283 U Rh-negative RBC was collected in Guangzhou Blood Center, accounting for 0.39% of total RBC collection (11 283/2 902 485); 1 693 U Rh-negative RBC was supplied, accounting for 0.43% of the total blood supply (11 693/2 762 229). The proportion of suspended RBC supply increased year by year, in contrast with the decease of proportion of frozen defrosteddeglyceal RBC supply. In addition, the growth rate of Rh-negative suspended RBC supply was higher than that of RBC collection since 2014 (F=217, P<0.05). A-and B-Rh negative suspended RBC supply increased, with growth rates of 137.3% and 134.1%, respectively. The Rh negative RBC was predominantly supplied to Grade III and general hospitals. Conclusion By establishing a team of Rh-negative regular blood donors, the strategies for recruitment, collection and supply of Rh-negative RBC should be continuously improved according to the characteristics of Rh-negative RBC collection and supply in Guangzhou. The coordinating management of Rh-negative, as well as the communication of clinical departments, departments of transfusion and blood banks should be improved. In addition, the balance between supply and demand of Rh-negative blood should be promoted, and the safety of blood transfusion for Rh-negative patients can be improved.

Objective To explore the personality status of urban primary school students in Guangzhou, to provide evidence and suggestions for personality traits, as well as physical and psychological health improvement of children in Guangzhou city.Methods This is a cross-sectional study. Cluster sampling was applied to the survey of personality traits in 405 grade-3 pupils from two primary schools of Guangzhou, using Junior Eysenck Personality Questionnaire (JEPQ). Independent t test was used to compare scores of all the dimensions in JEPQ between genders, age groups, and districts. Chi-square was used to compare proportion of high score in each dimension between districts. Results The standard T points of JEPQ in the dimensions of extroversion & introversion (E), neuroticism (N), psychoticism (P), lie (L) of Guangzhou city pupils were 50±11, 50±16, 42±18 and 50±10, respectively. Among them, 20.6% of subjects were emotionally unstable (T score＞61.5 in N dimension). 22.3% and 32.7% of children were introverted (T score＜43.3 in E dimension) and extroverted (T score＞56.7 in E dimension) respectively, and 6.3% of children were unsocial or aggressive (T score＞61.5 in P dimension). Compared with Chongqing, Chuzhou and Xi-an cities, the scores of E dimension were higher in both boys and girls of Guangzhou city (except for Xi-an girls, P<0.05). Conclusion Around twenty percent of Guangzhou city primary students tend to be anxious and nervous. Compared with the other cities, pupils in Guangzhou city are more extroverted. We suggested a three-in-one support network of school-community-family should be built to facilitate the children's physical and mental health development.

Objective To understand the registration situation and epidemic characteristics of tuberculosis patients in Haizhu district of guangzhou, and to provide a basis for further prevention and treatment of tuberculosis in Haizhu district. Methods The data of tuberculosis patients registered at present address in the TB information management system of Haizhu district from 2008 to 2017 were collected, and the registration data of tuberculosis patients were analyzed using descriptive epidemiological methods and relevant statistical methods. Results From 2008 to 2017, 14 384 cases of tuberculosis patients were reported in Haizhu district. The annual reported incidence rate decreased from 105.3/100,000 in 2008 to 73.1/100,000 in 2017, showing a down ward trend (χ² = 164.973, P<0.001). The relative incidence of male and female was 2:1; all age groups had morbidity, of which 25~34 years old group had the largest number of cases, accounting for 21.61% of the total number of cases; in occupational distribution, household chores and unemployed were the most, accounting for 34.48 %, followed by other (non-fixed occupations), accounting for 17.29%, retired people, accounting for 15.12%, and school students accounting for 5.52%. In terms of regional distribution, the average annual incidence rate of each street varied greatly, with the highest being 131.23/100,000 and the lowest being 66.40/100,000. The difference is statistically significant(χ²=164.973,P<0.001). Conclusion The incidence of tuberculosis in Haizhu district of Guangzhou has been decreasing year by year, but the incidence of tuberculosis in some streets is still more than 100/100,000. Male population, 25~34 years old group and low-income population (domestic and underemployed, irregular occupation, retired population) are the main population for prevention and control. Students have a large number of cases of tuberculosis, so we need to strengthen prevention, control and screening of tuberculosis in schools.

目的 分析广州市番禺区户籍和流动人口肺结核病发现延误情况,为研究结核病防治基本公共卫生服务均等化策略提供参考依据。方法 根据中国疾病预防信息系统登记的数据,对2013—2016年番禺区登记的肺结核病人进行统计。采用卡方检验的方法,对比分析户籍和流动肺结核病人发现延误的差异。结果 结核病发现延误中,男性患者户籍与流动患者延误天数比较差异有统计学意义(χ²=19.067,P<0.01),户籍患者延误天数30 d以上的比例高于流动患者。户籍与流动患者的医生延误天数比较差异有统计学意义,流动患者的医生延误比例高于户籍患者(χ²=18.001,P<0.01)。结论 广州市番禺区肺结核发现延误主要由户籍病人患者延误和流动病人医生延误所构成,需采取综合性干预措施,减少结核病患者的发现延误,从而进一步体现结核病防治基本公共卫生服务均等化。
