The healthcare aid to foreign countries undertaken by China is a challenging and honorable task.Healthcare aid team members often face numerous issues that can impact their physical and mental health.These factors may stem from their deployment in economically and socially marginalized regions characterized by poor healthcare infrastructure,diverse cultural and linguistic barriers,bringing challenges to both their work and mental health.Several elements such as substandard living condi-tions,cultural disparities,occupational stress,and homesickness can have a significantly detrimental effect on the physical and mental health of these medical aid personnel.By utilizing the case study of the sixth Chinese medical team deployed in Dominica,we aimed to thoughtfully consider and identify specific strategies to safeguard the physical and mental health of healthcare aid per-sonnel.By addressing these pivotal issues,we aspired to offer valuable insights and practical guidance for future healthcare aid personnel,hoping our reflections can facilitate more effective execution of their duties.

Objective:To explore the function of MDM2 and its relationship with p53 at the cellular level during H 2O 2 induced oxidative damage. Methods:MLE-12 HALI cell models were established using 0.5 mmol/L H 2O 2, and were divided into three groups: normal control group, H 2O 2 injury group, H 2O 2+MDM2 overexpressed group, and H 2O 2+MDM2 shRNA group. Infection of MLE-12 cells with adenovirus vector overexpressing and silencing MDM2; Using immunoprecipitation (Co-IP) to analyze the interaction between MDM2 and p53; Western blotting was used to detect the protein expression levels of MDM2, p53, Bcl-2, Bax, and cleared caspase-3 after HALI modeling; Measure the apoptosis rate of cells in each group. Results:After transcriptome sequencing,the p53 signaling pathway closely related to HALI. Compared with the normal group, the expression of MDM2 in the H 2O 2 injury group was lower ( P<0.05); Compared with the H 2O 2 injury group, overexpression of MDM2 resulted in a decrease in the apoptosis rate of MLE-12 cells ( P<0.05), a decrease in the expression levels of p53, Bax, and cleared caspase-3 proteins, and an upregulation of MDM2 and Bcl-2 protein expression ( P<0.05). Compared with the H 2O 2 injury group, when MDM2 was silenced, the cell apoptosis rate increased ( P<0.05), and the expression levels of p53, Bax, and cleared caspase-3 proteins were upregulated, while the expression levels of MDM2 and Bcl-2 proteins decreased ( P<0.05). Co-IP experiments showed that MDM2 binds to p53 protein. Conclusions:MDM2 can exert a protective effect on HALI by inhibiting MLE-12 cell apoptosis through the p53/Bcl-2/Bax axis.

Objective:To develop the Sexual Health Education Needs Assessment Scale for Breast Cancer Patients and test its reliability and validity.Methods:Guided by Maslow's hierarchy of needs theory and knowledge, belief, and practice theory, an initial scale was formed through literature review, semi-structured interviews and Delphi expert consultation. Through cognitive interviews with 9 patients, the scale was further revised and improved to form a clinical trial version. From December 2021 to September 2022, 397 breast cancer patients from 9 ClassⅢ hospitals in 6 provinces, municipalities and autonomous regions were selected by convenience sampling to conduct a questionnaire survey, test the reliability and validity of the scale and grade it.Results:The Sexual Health Education Needs Assessment Scale for Breast Cancer Patients included four dimensions and 32 items in total. Exploratory factor analysis extracted a total of four common factors, with a cumulative variance contribution rate of 72.258%. The content validity index of the scale was 0.865, and the content validity index of each item was 0.929 to 1.000. The correlation coefficients between each dimension of the scale and the total scale were 0.789 to 0.956, and the correlation coefficients between dimensions were 0.635 to 0.863. The Cronbach's α coefficient of the total scale was 0.979, and the Cronbach's α coefficients of each dimension were 0.897 to 0.969. The half reliability of the total scale was 0.941, and the half reliability of each dimension was 0.851 to 0.946. The total score of the scale was 32 to 160, with 32 to 77 being at a low level, 78 to 117 being at a medium level, and 118 to 160 being at a high level.Conclusions:The developed Sexual Health Education Needs Assessment Scale for Breast Cancer Patients has good reliability and validity, and is suitable for breast cancer patients' sexual health education needs assessment.

Objective:To investigate the current status of primiparas′ postpartum fatigue and paternal involvement, and to explore the relationship between primiparas′ postpartum fatigue and paternal involvement, and to provide reference basis for developing targeted intervention measures to alleviate postpartum fatigue of primiparas.Methods:A cross-sectional survey was conducted on 347 primiparas from Affiliated Hospital of Yangzhou University, Yangzhou Maternal and Child Health Care Hospital from September to December 2020 by convenience sampling. The survey instruments included the general information questionnaire, the Parenting Alliance Inventory (PAI), and the Postpartum Fatigue Scale (PFS).Results:The total score of PAI was (86.51 ± 12.07) points, and the level of paternal involvement was high. The total score of PFS was (16.68 ± 4.12) points. 95.97% (333/347) of primiparas had varying degrees of postpartum fatigue. There was a significant negative correlation between paternal involvement and primiparas′ postpartum fatigue ( r=-0.327, P<0.01). The results of multiple stratified regression analysis showed that paternal involvement was included in the influencing factor model of primiparas′ postpartum fatigue, which could independently explain 9.7% variation of primiparas′ postpartum fatigue. Conclusions:The higher level of paternal involvement could predict the lower level of primiparas′ postpartum fatigue. Medical staff should pay attention to the participation level of the spouses of primiparas in childcare, and improve the participation level of the spouses of primiparas in scientific ways to alleviate the postpartum fatigue of primiparas.

Objective:To analyze the potential risk factors of periventricular-intraventricular hemorrhage(PIVH)in premature infants.Methods:A retrospective study was conducted on clinical data of 279 premature infants admitted to the Affiliated Hospital of Guizhou Medical University From January 1, 2019 to December 31, 2019, who completed cranial ultrasound during hospitalization.According to the cranial ultrasound with or without PIVH, the cases were divided into PIVH group and non-PIVH group.The premature infants with PIVH were divided into severe PIVH(grade Ⅲ and Ⅳ)group and mild PIVH(grade Ⅰand Ⅱ)group according to the PIVH grades.A total of 25 factors, which may influnce PIVH, were analyzed by univariate analysis, and then multivariate Logistic stepwise regression analysis(stepwise backwards method)was performed to determine the major risk factors.Results:(1)A total of 279 premature infants were included in the study, 133 of them in PIVH group, and 146 of them in non-PIVH group.Univariate analysis showed that there were statistically significant differences in 14 factors between two groups, including full treatment of antenatal steroid, gestation age, birth weight, neonatal asphyxia, hypothermia, early onset sepsis, metabolic acidosis, hypernatremia, anemia, respiratory distress syndrome, noninvasive ventilation, invasive ventilation, invasive ventilation within 72 hours after birth, and lumbar puncture within 72 hours after birth( P<0.05). Multivariate analysis showed that gestational age( OR=0.709, 95% CI 0.602-0.835), and full treatment of antenatal steroid( OR=0.354, 95% CI 0.189-0.664) were protective factors for PIVH in premature infants, while neonatal asphyxia( OR=2.425, 95% CI 1.171-5.023), hypothermia( OR=2.097, 95% CI 1.088~4.041), early onset sepsis( OR=12.898, 95% CI 1.433-115.264), metabolic acidosis( OR=2.493, 95% CI 1.398-4.442), invasive ventilation within 72 hours after birth( OR=5.408, 95% CI 1.156-25.297), lumbar puncture within 72 hours after birth ( OR=5.035, 95% CI 1.269-19.993) were independent risk factors for PIVH in premature infants( P<0.05). (2) Among 133 cases of premature PIVH, 20 cases were severe PIVH and 13 cases were mild PIVH.Univariate analysis showed that there were statistically significant differences in 5 factors between two groups, including antenatal magnesium sulfate, gestation age, early onset sepsis, abnormal coagulation, and lumbar puncture within 72 hours after birth.Multivariate analysis showed that early onset sepsis( OR=4.392, 95% CI 1.343-14.367) and abnormal coagulation( OR=3.502, 95% CI 1.234-9.867) were independent risk factors for severe PIVH in premature infants( P<0.05). Conclusion:Gestational age is negatively correlated with the occurrence of PIVH in premature infants, and completion of more than a course of treatment for antenatal dexamethasone is an independent protective factor of PIVH in premature infants.Neonatal asphyxia, metabolic acidosis, hypothermia(<35 ℃), early onset sepsis, invasive ventilation within 72 hours after birth, and lumbar puncture within 72 hours after birth are independent risk factors for PIVH in premature infants.Abnormal coagulation and early onset sepsis are independent risk factors for severe PIVH in premature infants.

Objective To analyze the growth and development of children aged 6 to 14 years in Yangzhou City, Jiangsu Province, and to provide a basis for the evaluation of the growth and development and health care of local children. Methods In November 2020, a stratified cluster sampling method was used to investigate the physical development of 11 026 children aged 6 to 14 years in 9 primary and middle schools in Yangzhou. The results were compared with the current national standards in China. Results The BMI levels of children of all ages from 6 to 14 years in Yangzhou were higher than the national levels (t=6.947~20.093, P＜0.01). The heights of boys and girls were relatively close at pre-school age (t=1.348, P=0.025). Boys were slightly taller than girls at the ages of 6 to 8 and 10 to 11 years. At the ages of 9 and 12, girls were slightly taller than boys. Adolescent boys were significantly taller than girls. (t=15.161, P＜0.01). Conclusion In Yangzhou City, the height and weight development of students aged 6-14 years conform to the general growth and development trend, and their BMI is generally higher than the national average level.

OBJECTIVES: Idiopathic intracranial hypertension (IIH) is a syndrome that excludes secondary causes such as intracranial space-occupying lesion, hydrocephalus, cerebrovascular disease, and hypoxic ischemic encephalopathy. If not be treated promptly and effectively, IIH can cause severe, permanent vision disability and intractable, disabling headache. This study aims to explore the clinical and image features for IIH, to help clinicians to understand this disease, increase the diagnose rate, and improve the outcomes of patients. METHODS: We retrospectively analyzed 15 cases of IIH that were admitted to Xiangya Hospital, Central South University, during January 2015 to September 2020. The diagnosis of IIH was based on the updated modified Dandy criteria. We analyzed clinical data of patients and did statistical analysis, including age, gender, height, weight, medical history, physical examination, auxiliary examination, treatment and outcome. RESULTS: There were 10 females and 5 males. Female patients were 22 to 42 years old with median age of 39.5. Male patients were 27 to 52 years old with the median age of 44.0. The BMI was 24.14-34.17 (28.71±2.97) kg/m CONCLUSIONS IIH primarily affects women of childbearing age who are overweight. The major hazard of IIH is the severe and permanent visual loss. Typical image signs have high specificity in IIH diagnosis. Prompt diagnosis and effective treatment are significantly important to improve the outcomes of patients.

Objective:To investigate the acceptance and attitude toward a novel fecal immunochemical test (FIT) in colorectal cancer screening among populations in China.Methods:From May 2018 to May 2019, 2 474 people aged 50-74 years were recruited from five provinces of China (Zhejiang, Anhui, Jiangsu, Hunan and Yunnan). The general demographic characteristics, acceptance of the new FIT technology and operational difficulties through the whole screening process were obtained through questionnaire survey. Multivariate logistic regression model was used to analyze the factors related to difficulties encountered in sampling stool, reading and uploading results.Results:The subjects were (60.0±6.4) years old, and female, high school of above educated, unemployed/retired/other, married and with medical insurance status of “new rural cooperative medical care (NRCMC)” accounted for 61.7% (1 526), 29.0%(718), 34.3% (849), 92.7% (2 293) and 31.3%(775), respectively. The population's acceptance of the FIT technology was 94.8%. In the process of FIT screening, the percentage of occurred difficulties in sampling stool, reading and uploading results were 33.1% (819), 46.4% (1 147) and 62.9% (1 557), respectively. The main difficulties were the uncertainty about whether the sampling operation was standard (28.0%), the inability to accurately judge the result displayed (32.5%) and the need for help without using a smartphone (44.2%). The results of multivariate logistic regression model analysis showed that people aged 65-74 years old and with medical insurance status of “NRCMC” were more likely to encounter difficulties in sampling, and those who were unemployed/retired/other and living with 3 or more family members were less likely to encounter difficulties in sampling. Those aged 65-74 years old, farmers or migrant workers, and those with “NRCMC” were more likely to encounter difficulties in readingresults, and those with 3 or more family members were less likely to encounter difficulties in reading result. Those with “NRCMC” were more likely to encounter difficulties in uploading results, and those with education level of high school or above, living with more than 3 family members were less likely to encounter difficulties in uploading results.Conclusion:The acceptance of the new FIT technology is relatively high among the subjects. Age, education level, occupation, number of family members living together and medical insurance status might be related to difficulties encountered in sampling stool, reading and uploading results, and it can be further strengthened in terms of the technology and characteristics of sub-populations.
