Objective To survey the current status of human resources of the Anesthesiology in Chi-na and investigate the reform direction of human resources allocation of Chinese medical and health system. Methods Chinese Society of Anesthesiology organized the investigation from March 1, 2015 to June 30, 2015.All the hospitals in which clinical anesthesia was carried out were investigated only in mainland Chi-na.The questionnaires contained hospital general information, anesthesia-related information and surgery-re-lated information.Results A total of 16 280 questionnaires were released and 14 076 questionnaires (86.462%)were retrieved.There were 13 489 questionnaires(82.856%)identified as qualified anesthesia-related information ones and 7 026 questionnaires(43.157%)identified as qualified surgery-related informa-tion ones.Qualified anesthesia-related information questionnaires showed that there were 77 926 anesthesiolo-gists in total in China, 27 660 000 patients in whom anesthesia was completed inside operating room(OR)and 11 470 000 cases outside OR, one attending anesthesiologist completed anesthesia in 634 cases inside OR and in 263 cases outside OR on average; the number of per capita anesthesiologists was 5.7 per 100 000 pop-ulation in 2014.The number of per capita physicians per 10 000 population(r=0.735, P<0.05), the num-ber of anesthesiologists per 100 000 population(r=0.537, P<0.05)and the number of per capita patients requiring anesthesia per 100 000 population(r=0.571, P<0.05)were all positively correlated with GDP per capita in various provinces and cities nationwide and autonomous regions.The area having the highest num-ber of per capita anesthesiologists per 10 000 and per 100 000 population was Beijing, the area having the lowest number was Tibet; the area having the highest number of per capita patients requiring anesthesia per 100 000 population was Beijing, the area having the lowest number was Shanxi. The qualified surgery-related information questionnaires showed that the ratio of attending surgeons to attending anesthesiologists was 7.5:1.0 in China in 2014.Conclusion Although China has a huge number of anesthesiologists, the Anesthesiolo-gy is still shortage of anesthesiologists; the imbalanced distribution of human resources exists in different provinces and cities, in hospitals of different scales and between different medical specialties, and economics is one of the important influencing factors.

Objective:To study the effect of the psychological counseling on the delivery mode of single birth elderly primiparas with anxiety and depression, and to seek a new and effective intervention way to improve the vaginal delivery rate.Methods:A preliminary screening was carried out for 486 single birth elderly primiparas received in the birth cohort research center of China Medical University from April 2018 to September 2019. Among them, 274 cases had mild, moderate or severe anxiety and depression. They were randomly divided into the observation group and the control group (n=137). The control group was given routine nursing measures and simple psychological education and the intervention group was given extra psychological counseling. Psychological counseling adopted the mode of combination of online and offline. The degree of anxiety and depression and the delivery mode were compared between two groups.Results:Before intervention, the degree of anxiety and depression between the observation group and the control group showed no significant difference. After intervention, the degree of anxiety and depression in the observation group was lighter than that of the control group ( χ2 value was 12.782, 6.647, P<0.05). The proportion of cesarean section, vaginal delivery, forceps delivery accounted for 32.1% (44/137), 67.2%(92/137), 0.7%(1/137) in the observation group, and 45.3% (62/137), 54.7%(75/137), 0 in the control group. The difference between the two groups showed statistical significance ( χ2 value was 5.787, P<0.05). Conclusion:The psychological counseling for the single birth elderly primiparas with anxiety and depression can effectively improve the psychological situation and increase the vaginal delivery rate.

Persistent Organic Pollutants (POPs) have the characteristics of resistance to environmental degradation, bioaccumulation and long-distance migration potential. Maternal exposure to POPs during pregnancy can enter the fetal blood circulation through the placental barrier, and have a potential impact on the functional development of the nervous system of the offspring. This in turn leads to the occurrence and development of neurological defects and diseases in adulthood. The purpose of this paper is to elucidate the effects of exposure to three major POPs (organochlorine compounds, perfluoroalkyl and polyfluoroalkyl substances, and polybrominated diphenyl ethers) during pregnancy on the functional development of the nervous system (social emotions, cognition, language, exercise, and adaptability) in children, and to provide reference for subsequent studies.
