Objective To understand the equity and influencing factors of maternal health service utilization in Changning District, Shanghai. Methods A convenience sampling method was used to conduct a questionnaire survey among mothers of children aged 1 to 1.5 years old who received health services from the child health care clinics and EPI clinics of 10 community health service centers in Changning District, Shanghai from March to April 2022. Count data was expressed by frequency and percentage. Chi-square analysis, binomial logistic regression analysis, and multivariate logistic regression analysis were used to analyze fairness-related factors. Rate difference, rate ratio and concentration index were used to represent fairness. Results A total of 696 subjects were investigated, with an average age of (33.35±4.76) years. There were statistically significant differences in service utilization among women with different household registrations only in early pregnancy registration (χ²=11.026, P=0.001) and postpartum visits (χ²=4.989, P=0.026). Women with a career showed differently in folic acid supplement (χ²=6.247, P=0.012), early pregnancy registration (χ²=12.989, P=0.002), physical examination in 42 days postpartum (χ²=4.446, P=0.035) and postpartum contraception (χ²=4.061, P=0.044), and the differences were statistically significant. Women with different monthly family income had a statistically significant difference in pre-pregnancy examination (χ²=8.977, P=0.030) and postpartum visit (χ²=16.114, P=0.001). There was a statistically significant difference between women with maternity insurance or not in the early pregnancy registration (χ²=10.576, P=0.001) and physical examination in 42 days postpartum (χ²=8.166, P=0.004). The results of the multivariate analysis showed that occupation (OR=2.616, 95% CI: 1.142-5.990) and maternity insurance (OR=4.490, 95% CI: 1.992~10.120) affected the utilization of service in early pregnancy registration. The monthly household income (OR=0.278, 95% CI: 0.124-0.625) affected the utilization of services in postpartum visit. At the same time, the monthly household income (10,000-19,999: OR=0.286, 95% CI: 0.090-0.907; ≥30,000: OR=0.180, 95% CI: 0.041-0.801) also affected the utilization of service in physical examination in 42 days postpartum. Conclusion The equity of maternal health care service utilization overall is good in central area in Shanghai, but there is still room for improvement. It is necessary to strengthen community mobilization, propagandize maternal health services, and expand the coverage of maternity insurance to improve the equity of maternal health service utilization and provide equal access to maternity health services.

Objective To investigate the value of peripheral blood T-lymphocyte subsets and mitochondrial damage index(MDI)in evaluating the pregnancy outcome of patients with diminished ovarian reserve(DOR).Methods A total of 230 DOR patients admitted to the hospital from August 2020 to August 2023 were selected as DOR group,230 healthy women with normal ovarian reserve function were selected as control group,and all subjects were tested for peripheral blood T-lymphocyte subsets and MDI.DOR patients were di-vided into clinical pregnancy group(n=86)and non-clinical pregnancy group(m=144)according to clinical pregnancy.The influencing factors of pregnancy outcomes of DOR patients were analyzed by multivariate Lo-gistic regression model,and the predictive value of peripheral blood T-lymphocyte subsets and MDI for poor pregnancy outcomes of DOR patients was analyzed by receiver operating characteristic(ROC)curve.Results Com-pared with control group,CD3+,CD4+and CD4+/CD8+in DOR group were decreased(P＜0.05),and CD8+,positive rate of helper T cell(Th)-MDI and positive rate of suppressor T cell(Ts)-MDI were increased(P＜0.05).The clinical pregnancy rate of 230 DOR patients was 37.39％(86/230).Compared with clinical pregnancy group,CD4+in non-clinical pregnancy group was decreased(P＜0.05),and CD8+,CD4+/CD8+and the positive rates of Th-MDI and Ts-MDI were increased(P＜0.05).There was no significant difference in CD3+between two groups(P＞0.05).The levels of anti-Müllerian hormone(AMH)and estradiol(E2)in non-clinical pregnancy group were lower than those in clinical pregnancy group(P＜0.05).Th-MDI positive and Ts-MDI positive were independent risk factors for poor pregnancy outcomes in DOR patients(P＜0.05),and high levels of CD4+/CD8+,AMH and E2 were protective factors for poor pregnancy outcomes in DOR patients(P＜0.05).The area under the curve of AMH,E2,CD4+/CD8+,Th-MDI,Ts-MDI alone and com-bined in predicting poor pregnancy outcome in DOR patients were 0.735,0.784,0.767,0.691,0.703,0.882,respectively,and the predictive efficacy of combined application was significantly higher than that of each sin-gle application(P＜0.05).Conclusion DOR patients have immune dysfunction and oxidative activation,low CD4+/CD8+,Th-MDI positive and Ts-MDI positive are risk factors for poor pregnancy outcomes in DOR pa-tients,and the detection of the three has a high predictive effect on poor pregnancy outcomes in DOR patients.

This paper summarized Professor ZHOU Zhongying's experience in differentiating and treating hepatitis and liver cirrhosis from deficiency and excess. It is considered that the pathogenesis of hepatitis and liver cirrhosis belongs to deficiency in root and excess in branch， with depletion of liver， spleen and kidney as the root， and constraint and bind of damp-heat and stasis toxin as the branch. Moreover， mutual cause and promotion between deficiency and excess leads to the disease. For general principle of treatment， it is recommended to clear and transform pathogenic excess， supplement deficiency and rectify the healthy qi. In the early stage of hepatitis and cirrhosis， excess pathogen hyperactivity is the main manifestation， which can be treated by clearing and transforming damp-heat and stasis toxin， supplemented by regulating spleen and stomach， with modified Yinchenhao Decoction （茵陈蒿汤） and Biejiajian Pill （鳖甲煎丸）. In the middle and late stages， cases with deficiency-excess complex were more common， which should be treated by clearing damp-heat and stasis toxin， regulating and supplementing liver-spleen-kidney， using medicinals with the function of clearing heat and dispelling damp， dissolving stasis and resolving toxins to treat the branch. Moreover， Liujunzi Decoction （六君子汤）， Yiguan Decoction （一贯煎）plus Erzhi Pill （二至丸） and Buzhong Yiqi Decoction （补中益气汤） modifications are suggested respectively in correspondence to the different kinds of root deficiency including irregular liver and spleen， liver and kidney yin deficiency， and liver-spleen-kidney deficiency.

It is believed that retention due to deficient qi is an important pathogenesis of endometriosis （EMs）. Deficient qi is the root of the disease， mainly manifested as spleen deficiency， while retention is the branch pathogenesis of the disease， mainly with blood stasis， complicated with constraint， phlegm， heat， toxin and other pathological factors. Therefore， it is proposed to follow the treatment principle of supplementing deficiency and unblocking stagnation， and take the methods of replenishing qi and fortifying the spleen， removing stasis and eliminating concretions. Self-made Fuzheng Huayu Formula （扶正化瘀方） is taken as the basic formula， and can be modified with the symptoms in menstrual and non-menstrual periods. Additionally， the methods of moving qi， dispelling phlegm， clearing heat， relieving toxin and others can be combined， and it is recommended to treat the root and the branch simultaneously.

Objective To study the effects of antibiotics and high-fat diet on energy metabolism and the browning of white adipose tissue (WAT) and brown adipose tissue (BAT) in mice, so as to provide new ideas for the possible mechanism of adipose tissue in the prevention and treatment of obesity. Methods A total of 80 10-week-old C57BL/6 male mice were fed with normal diet in the early stage, and the antibiotic gavage group (AG) and antibiotic high-fat group (AFG) were given mixed antibiotics by gavage. The blank group (BG) and the high-fat diet group (FG) were given normal saline intragastric solution for 2 weeks, and after the gavage operation, the FG group and the AFG group were given high-fat diet for obesity modeling, and the BG group and AG group continued to be fed with normal diet for 8 weeks (N=20). After the experiment, each group was injected with β3-adrenergic receptor agonists for 5 days, and the high-fat/ordinary diet remained unchanged. At the end of the experiment, basal metabolic rate (BMR), fasting blood glucose (FBG) and rectal temperature were measured, and feces, blood, subcutaneous white fat, epididymis and brown adipose tissue in the scapular area of mice were collected. The automatic biochemical analyzer was used to determine the blood biochemical indexes; reverse transcription polymerase chain reaction (RT-qPCR) was used to measure the expression of genes related to browning of WAT and BAT adipose tissue, respectively. Real-time quantitative polymerase chain reaction (qPCR) was used to determine the expression of WAT mitochondrial DNA (mt DNA). Results From the 4th week to the end of the experiment, the weight of the AFG group was significantly higher than that of the AG group and significantly lower than that of the FG group (P<0.05). The body weight, organ coefficient, serum TC level, rectal temperature and WAT cell diameter in the AFG group were significantly higher than those in the AG group. The serum levels of FBG, TC and LDL in the AFG group were significantly lower than those in the FG group (P<0.05). The overall BMR(mlO2/h) FG group was significantly higher than that of BG group, and the AFG group was significantly higher than that of AG. BMR per unit body weight (mlO2/h/g) AFG was significantly higher than that of FG group (P<0.05). The expressions of RIP140, PPAR-γ and UCP-1 in BAT in the AFG group were significantly higher than those in the FG group, and the mt DNA copy number of WAT in the AFG group was significantly higher than that in the FG group (P<0.05). Conclusion Antibiotic intervention can up-regulate the expression of brown fat-related genes in high-fat diet mice, increase brown fat activity, increase the relative mitochondrial number of white fat, increase the level of browning of white fat, promote thermogenesis, increase the BMR per unit body weight of adult obese mice, and then improve the overall energy metabolism of the body, and slow down the weight gain induced by high-fat diet to a certain extent.

Aim To investigate the effects of multi-gly-cosides of Tripterygium wilfordii(GTW)on mitochon-drial dynamics-related proteins and the mechanism of nephroprotective effects in IgA nephrophathy(IgAN)rats.Methods SPF grade male SD rats were random-ly divided into the Control group,modelling group,prednisone group(6.25 mg·kg·d-1)and GTW group(6.25 mg·kg·d-1).The IgAN rat model was established by the method of"bovine serum albumin(BSA)+carbon tetrachloride(CCl4)+lipopolysac-charide(LPS)".The total amount of urinary protein(24 h-UTP)and erythrocyte count in urine were meas-ured in 24 h urine.Blood biochemistry of serum albu-min(ALB),alanine aminotransferase(ALT),urea ni-trogen(BUN),and creatinine(Scr)were measured in abdominal aorta of the rats;immunofluorescence and HE staining were used to observe the histopathology of the kidneys;RT-PCR and Western blotting were used to detect the mRNA and protein expression levels of key proteins regulating mitochondrial division and fu-sion:dynamin-related protein 1(Drp1),mitochondrial fusion protein 1(Mfn1),and mitochondrial fusion pro-tein 2(Mfn2),and PTEN-induced putative kinase 1(Pink1),in the kidney tissue of rats.Results GTW significantly reduced urinary erythrocyte count and 24 h-UTP,decreased serum ALT,BUN and Scr levels,in-creased serum ALB levels,improved renal histopatho-logical status in IgAN rats,increased the protein and mRNA expression levels of Mfn1,Mfn2,and Pink1,and decreased the protein and mRNA expression levels of Drp1 in renal tissues.Conclusions GTW may regu-late mitochondrial structure and maintain the dynamic balance of mitochondrial dynamics by promoting the ex-pression of Mfn1,Mfn2,Pink1 and decreasing Drp1.This may result in a reduction in urinary erythrocyte counts and proteinuria,and an improvement in renal function.

Aim To explore the mechanism of action of Tripterygium glycosides tablets on kidney of rats with IgA nephropathy based on inflammation-related path-ways.Methods Forty-five male SD rats of SPF grade were randomly divided into control group and modeling group.In addition to the blank group,the modeling group used the combination of bovine serum albumin(BSA)+carbon tetrachloride(CC14)+lipopolysac-charide(LPS)to establish the IgA nephropathy rat model.Successfully modeled rats were randomly divid-ed into the model group,the prednisone group and Tripterygium glycosides tablets group,and the treat-ment group was given the drug by gavage from the 13 th week,and the 24 hours urine,blood and kidney tis-sues of the rats were collected and examined after 4 weeks of the administration of the drug.Urine erythro-cyte count,quantitative 24-h urine protein(24 h-UTP),urea nitrogen(BUN),and blood creatinine(Scr)were detected in each group;serum interleukin 1β(IL-1β)and tumor necrosis factor α(TNF-α)were detected by enzyme-linked immunosorbent assay(Elisa);the pathological changes in the renal tissues of the rats in each group were observed by horizontal hematoxylin-eosin(HE)staining;and the renal tis-sues in each group were observed by Western blotting.The expressions of LIGHT,HVEM,LTβR proteins and their mRNAs in rat kidney tissue were detected by Western blot and real-time fluorescence quantitative polymerase chain reaction(RT-PCR).Results Tripterygium glycosides tablets significantly reduced the levels of urinary erythrocyte count,24 h-UTP,BUN,and Scr in IgA nephropathy rats(P＜0.01),improved renal histopathology,lowered the levels of se-rum inflammatory factors IL-1β and TNF-α(P＜0.01),and lowered the levels of LIGHT,HVEM,LTβR proteins and their mRNA expression in renal tis-sues(P＜0.01).Conclusions Tripterygium glyco-sides tablets may inhibit the immune response and re-duce the release of inflammatory factors by down-regu-lating the LIGHT-HVEM/LT(3R pathway,thus reduc-ing the inflammatory response,lowering the urinary e-rythrocytes and urinary proteins,improving the renal nephron pathologic injury,and protecting the renal function.

Objective To explore the effect of mixed antibiotics on the intestinal flora of mice to affect the immune regulation of the body,explore the role of intestinal flora in the development of obesity,and provide new ideas and ways for the prevention and treatment of obesity.Methods Seventy-two 10-week-old male C57BL/6 mice were randomly divided into blank control(Ctrl)group,high-fat diet(HF)group,antibiotic(ABX)group,and combined(COMB)group(n=18).At the first 2 weeks(lavage intervention weeks),Ctrl and HF group were given normal saline gavage;ABX and COMB group were given mixed antibiotics gavage,and the gavage volume was 0.2 mL/animal/day.For the following 8 weeks(feeding weeks),Ctrl and ABX group were fed with ordinary diet,HF and COMB group were fed with high-fat diet.Body weight was measured weekly,and fasting blood glucose was measured before and after gavage,and at the 4th and 8th week of feeding.Oral glucose tolerance test was performed at the end of the experiment.The organ coefficient was measured and the cell morphology of white and brown adipose tissue was observed.Serum was collected for the determination of free fatty acid,high-density lipoprotein,low-density lipoprotein,triglyceride,and total cholesterol.Serum TNF-α,IL-10,IL-4,IL-13,IL-33 and MCP-1 was detected by ELISA.The stool of mice was collected for second generation sequencing.Results High-fat diet increased body weight,serum total cholesterol,low-density lipoprotein,IL-13,IL-33,TNF-α,MCP-1 content,and decreased glucose tolerance and organ coefficient in mice(P＜0.05).From the first feeding week to the end of the experiment,body weight in COMB group was significantly lower than that in HF group(P＜0.05).The level of glucose tolerance,serum total cholesterol,low density lipoprotein,IL-13,IL-33,TNF-α and MCP-1 in COMB group was lower than those in HF group(P＜0.05).The α diversity of intestinal flora in ABX group was lower than that in Ctrl group(P＜0.05).Congestion and bleeding in WAT were obvious in HF group,but not in COMB group.The microbial community composition of ABX and HF group was similar to that of Ctrl and COMB group,respectively.Conclusion High-fat diet induces obesity,disorder of glucose and lipid metabolism and inflammation in mice.Short-term mixed antibiotic use can regulate the intestinal flora of mice,mediate increased expression of related anti-inflammatory factors,up-regulate host immunity,and improve glucose and lipid metabolism in mice.

Objective To investigate the social support needs of medical staff in Guangzhou during the post-COVID-19 period,providing a basis for relevant departments to offer targeted social support for medical staff in Guangzhou and improve their of occupational quality of life.Methods A cross-sectional survey was conducted,employing a combination of quota and conven-ience sampling to select subjects,eligible medical staff were invited to complete an online questionnaire.Results The social sup-port with a total score of 20 for medical staff in Guangzhou scored 9(7,11).Among the dimensions of social support,media sup-port scored the lowest.Social support as a whole scored with statistically significant differences across groups of different age,ed-ucational background,and job position(all P＜0.05).The median score was the lowest for those under 25 years,for those with a college degree or below,and highest among administrative staff,with other positions showing equal median score.The five di-mensions of social support ranked on the top concerning the total number of the respondents included patients'understanding and trust for medical staff(93.03％),increasing in salaries and benefits(86.06％),accurate policy promotion and public opinion guidance by media(83.41％),attention to the living conditions of medical staff by media(80.29％),and enhanced regulation of false reporting and inappropriate commentary by media(76.92％).Medical staff under the age of 25 had a high need for pa-tients'following doctor's advice,and medical staff with a collegiate degree or below had a high need for family members or friends to care about their physical and mental health.The five strongest needs for social support ranked on the top concerning the total number of respondents included understanding and trust from patients(75.72％),increased salaries and benefits(53.85％),assistance with household matters by family or friends(42.55％),correct policy promotion and public opinion guidance by media(34.62％),and attention to the living conditions of medical staff from media(33.41％).Conclusion Social support for medical staff in Guangzhou are at a relatively low level,indicating a need for social support from all levels of society.
