Objective To construct,implement and evaluate the effectiveness of the virtual simulation technology-based prenatal health education course.Methods The curriculum included 4 parts:"warm delivery room and easy delivery","medicated analgesic delivery","non-medicated analgesic delivery"and"early maternal and infant health care".From May to September 2022,100 primiparas in an obstetrics and gynecology hospital in Zhejiang Province were investigated by convenient sampling method.Random number table method was used to divide the participants into an experimental group and a control group,with 50 participants per group.The control group received conventional health education,while the experimental group received an augmented virtual reality technology-based prenatal health education course during the late stages of pregnancy on this basis.We conducted a post-intervention comparative analysis of antenatal anxiety levels,fear of childbirth,and birth outcomes between the 2 groups.Furthermore,a post-intervention satisfaction survey was administered to the experimental group.Results After intervention,the antenatal anxiety of the experimental group was lower than that of the control group(x2=4.943,P=0.026),and the decrease in fear of childbirth scores was higher than that of the control group(t=3.200,P=0.002).The experimental group was highly satisfied with all of the 4 dimensions of the course,and the overall evaluation was(31.8±3.23)points.However,there were no significant differences in vaginal delivery rate,postpartum bleeding volume,postpartum hemorrhage incidence,perineal injury degree and duration of each labor stage between the 2 groups(P＞0.05).Conclusion The virtual reality technology-based prenatal health education course was effective in improving the antenatal anxiety and fear of childbirth of primipara,and the use satisfaction is high.

The report summarized the experience in perinatal nursing for 1 case of third trimester complicated with pulmonary arteriovenous fistula.The highlights of nursing for the case were as follows.A professional team was set up for division and cooperation of labor in perinatal nursing;relevant conditions were identified precisely,and relevant emergency care was well done;appropriate methods for pregnancy termination and anesthesia were selected,and relevant intraoperative nursing was performed smoothly;a whole process of fine management was adopted,and the occurrence of serious complications was prevented effectively;personalized guidance for breastfeeding was provided after delivery.After the comprehensive management of the multidisciplinary team,both mother and baby were discharged safely.

Objective:To explore the clinical effects of a series of posture intervention strategies on correcting abnormal fetal position, so as to provide a basis for Clinical position management and promotion of natural delivery.Methods:This study was a randomized controlled trial. The convenience sampling method was used to select 196 full-term primiparas women with abnormal fetal orientation confirmed by ultrasound as single fetal head position in the Women′s Hospital, School of Medicine, Zhejiang University from March to October 2022 as the research objects. They were divided into control group 106 cases and research group 90 cases by random number table method. The control group received normal nursing and chose comfortable position by themselves during labor. The research group received a series of ultrasound-guided postural intervention strategies for postural management in the first and second stages of labor on the basis of normal nursing. The angle of progression and the midline angle, the fetal orientation, fetal orientation during complete uterine orifice and delivery outcome were compared between the two groups.Results:Finally, 190 cases were included, 105 cases in the control group and 85 cases in the research group. There were 76 vaginal deliveries in the research group and 95 in the control group. The rate of anterior occipital position and the angle of fetal head rotation in the research group were 73.68% (56/76) and 64.55 (37.90, 85.55)°, which were higher than 45.26% (43/95) and 33.00 (14.00, 60.00)° in the control group;the midline angle of the research group was 57.10(38.50, 75.80)°, which was lower than 80.00 (52.50, 90.30)° of the control group. There was significant difference between the two groups ( χ2 = 14.14, Z = 4.17, - 3.74, all P<0.01). The first stage of labor was 522.50 (413.00, 695.00) minutes and the total stage of labor was 611.00 (488.00, 812.00) minutes in the research group, which was lower than 620.00 (450.00, 795.00) and 700.00 (539.00, 904.00) minutes in the control group ( Z = - 2.34, - 2.03, both P<0.05). Conclusions:The application of the serial position intervention strategy under the ultrasound guidance during the labor process can improve the abnormal fetal position, shorten the first stage of labor time effectively and safely, while it does not have any significant effect on the improvement of the delivery outcome.

Objective:To summarize the nursing care experience of intrauterine infection complicated with septic shock in middle pregnancy for a patient with recurrent spontaneous abortion and postpartum hemorrhage during anti shock treatment.Methods:On June 2020, one patient with recurrent spontaneous abortion was admitted to our hospital with intrauterine infection in the second trimester of pregnancy. Close observation of disease changes, formulate personalized emergency plan, respond quickly when the condition changes, cooperate closely and actively rescue, observation and nursing of postoperative hemorrhage, anti-infective therapy timely, psychological nursing and health education. After active rescue and careful nursing, the patient recovered and discharged 8 days after abortion.Results:After active treatment and careful nursing, the patient recovered well and recovered 8 days after operation.Conclusion:For patients with intrauterine infection, especially patients with recurrent spontaneous abortion, close observation , timely initiation of emergency plans, termination of pregnancy effective anti-infection treatment, and psychological nursing and health guidance are essential to ensure the life safety of patients and promote reproductive health.

Recent years, national laws and government policies were published as series to encourage the development of group standardizations. The updated Standardization Law of the People's Republic of China, implemented on January 1^st, 2018, stipulates that group standard is a part of the Chinese standard system. Under the current supportive circumstances, more institutes and organizations have joined in the writing and releasing procedures of group standards’. Despite the rapid development of group standardization to publish, we are still at the phase of exploring and regulating group standardizations. This review summarizes the development and practice on the development group standardization in the Chinese Preventive Medicine Association and analyzes current condition and deficiency of the work in China, in order to develop suggestions and strategies to improve and regulate group standardization.

Discordance, such as overlap, repetition and inconsistent, of standards is one of the major problems in current standardization affair in China. Therefore, improving the unity and authority of standards through reduction of overlap, repetition and inconsistency has become the main goal of deepening standardization reform in China. This paper summarizes the discordance in public health standards in China, analyzes the major reasons and provides specific strategic suggestions through case analysis of public health standards in the ways of comparisons of same kind standards of other deparments and standards in administration documents and guidelines or technical specifications of academic associations or societies.

Objective: To explore the association of arsenic with unexplained recurrent spontaneous abortion (URSA). Methods: A case-control study was conducted to select URSA patients who were admitted to the Beijing Maternal and Child Health Care Hospital affiliated to Capital Medical University from April to October 2018 as a case group. Women who had a normal pregnancy in the Family Planning Department of the hospital but volunteered to have an abortion were selected as a control group. The case and control group were paired in a 1: 1 ratio. The inclusion criteria of the case group were patients with newly diagnosed recurrent spontaneous abortion who had clinically confirmed more than 2 spontaneous abortions and had 20 weeks prior to pregnancy, excluding patients with recurrent spontaneous abortion caused by abnormal blood coagulation (anti-phospholipid antibody positive), abnormal physiological anatomy (B-ultrasound), abnormal immune factors (anti-nuclear antibody positive, anti-cardiolipin antibody, etc.), genetic chromosomal abnormalities (karyotype analysis) and pathogenic microbial infection. The control group was matched according to the age of the case group (±3 years old) and the gestational age (±2 weeks) to exclude adverse pregnancy outcomes such as stillbirth, congenital malformation, premature delivery and low birth weight infants. A total of 192 subjects were included. Questionnaires were used to collect information of all subjects, and 12 ml of peripheral venous blood was collected to detect blood arsenic levels. Blood arsenic levels were divided into low concentration group (<1.00 μg/L), medium concentration group (1.00-1.50 μg/L) and high concentration group (>1.50 μg/L). The multivariate conditional logistic regression was performed to analyze the relationship between blood arsenic exposure and URSA and explore the influencing factors of blood Arsenic. Results: The geometric mean values of blood arsenic level in the cases group and control group were 1.68 (1.50-1.86) μg/L and 1.26 (1.17-1.37) μg/L, respectively. The blood arsenic level in the case group was significantly higher than that in the control group (P<0.05). The results of multivariate conditional logistic regression analysis showed that after adjusting for tobacco exposure during pregnancy, pre-pregnancy body mass index and the effects of residential decoration in past five years, the risk of URSA was higher in the high-concentration group compared with the low-concentration group (OR=2.56, 95%CI:1.06-6.24). Conclusion Blood arsenic may increase the risk of URSA in women of childbearing age.
