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 know about the perception and current status of drug risk management among pharmacists in Chinese medical institutions,providing insights and recommendations for enhancing the drug risk management system in medical institutions.METHODS A questionnaire survey was conducted across 28 provinces,cities,and autonomous regions;stratified radom sampling was employed to study the population of medical workers and pharmaceutical professionals in medical institutions nationwide.The survey included information on the survey population,the current status of drug risk management implementation in medical institutions,the cognition,definition and process of drug risk management related concepts,and the content and mode of drug risk management work in medical institutions.Finally,suggestions were collected from various medical institutions on the system construction of drug risk management.Descriptive statistical analysis was adopted to summarize the obtained data.RESULTS A total of 446 questionnaires were collected in this survey,including 420 valid questionnaires and 26 invalidquestionnaires.The questionnaire collection rate was 100％,and the effective rate was 94.17％.51.19％ of the respondents based their understanding of drug risk management on Management Measures for Adverse Drug Reaction Reports and Monitoring,while 87.38％ recognized the need for drug risk management throughout the drug use process.63.33％ of the participants stated that their medical institutions had dedicatedpositions related to drug risk management,with the highest proportion (72.17％) was in third-grade class A medical institutions.66.43％ reported implementing risk management across all drug use stages.Suggestions for the development of drug risk management systems in medical institutions by the research participants focused on enhancing guiding documents,clarifying concepts,establishing information-sharing mechanisms.CONCLUSIONS The overall awareness of drug risk management in China's medical institutions is high,with practices in place across various stages in multiple forms.However,there remains a need to strengthen institutional documents,management regulations,system development,and information-sharing mechanisms to improve collaborative governance,improve drug management levels,and ensure patient safety.

AIM: To compare the efficacy of intravitreal injection of ranibizumab(IVR)and intravitreal injection of conbercept(IVC)in children with retinopathy of prematurity(ROP).METHODS: Retrospective study. A total of 1 100 eyes with ROP treated with intravitreal anti-VEGF at our hospital from January 2015 to June 2023 were included. According to the different therapeutic drugs, the children were divided into two groups: IVR group and IVC group. According to the degree of ROP, the patients were divided into three groups: aggressive ROP(A-ROP), Zone Ⅰ type 1 ROP and Zone Ⅱ type 1 ROP. The reactivation and retreatment between the two groups were compared after propensity score matching(PSM)analysis, and they were followed-up for at least 3 mo after surgery.RESULTS: In Zone Ⅱ type 1 ROP, there was a statistically significant difference in the rates of reactivation and retreatment between the IVR and IVC groups(P<0.05); however, in A-ROP and Zone I type 1 ROP, there were no statistically significant differences in the rates of reactivation and retreatment between the two groups(P>0.05). The risk of reactivation and retreatment of Zone I type 1 ROP was higher than the Zone II type 1 ROP. Furthermore, the use of drugs and corrected gestational age of first treatment were influencing factors of lesion recurrence and retreatment.CONCLUSION: There is a significant difference in the initial cure effect between the two drugs in Zone II type 1 ROP, with the reactivation and retreatment rates of the IVC group being much lower than those of the IVR group.

Objective:To investigate the relationship between serum calcium levels and pain in patients with Parkinson's disease(PD).Methods:A total of 111 patients with PD and 50 healthy volunteers were recruited from our hospital between July 2019 and June 2020.Motor symptoms of PD patients were assessed using the Hoehn-Yahr(H&Y)stages and the Unified Parkinson's Disease Rating Scale-Ⅲ(UPDRSⅢ).Non-motor symptoms were evaluated using Mini-Mental State Examination(MMSE), 17-item Hamilton Depression Rating Scale(HAMD-17), 14-item Hamilton Anxiety Rating Scale(HAMA-14), questionnaire for rapid eye movement(REM)sleep behavior disorder(RBDQ-HK), King Parkinson's pain scale(KPPS), Pittsburgh Sleep Quality Index(PSQI), Parkinson's Disease Sleep Scale(PDSS), and Epworth Sleepiness Scale(ESS).The quality of life of PD patients was assessed using the 39-item Parkinson's Disease Questionnaire(PDQ-39).Results:The levels of serum calcium in PD patients were significantly lower than those in the control group( t=3.733, P<0.001).Additionally, the levels of serum calcium in PD patients with pain were higher than those in PD patients without pain( t=-3.238, P<0.05).This suggests a significant positive correlation between serum calcium levels and pain in PD patients( r=0.320, P=0.001).When analyzing serum calcium levels for PD with pain using binary logistic regression, the area under the curve(AUC=0.662)and sensitivity(28.9%)were found to be low.Furthermore, a correlation analysis of KPPS scores in PD patients with pain revealed that KPPS scores were correlated with UPDRSⅢ( r=0.383, P=0.009), HAMD-17( r=0.303, P=0.043), HAMA-14( r=0.303, P=0.043), PSQI( r=0.304, P=0.042), and PDSS( r=-0.417, P=0.004)scores. Conclusions:The levels of serum calcium are decreased in patients with Parkinson's disease(PD), and there is a correlation between serum calcium levels and pain experienced by PD patients.However, it is important to note that pain in PD patients is influenced by various other factors.

Objective To investigate the role of miR-125b on hepatic angiogenesis,with the hope of providing new targets for the prevention and treatment of liver fibrosis.Methods The human hepatic sinusoidal endothelial cells were transfected with miR-125b mimics and inhibitors,and the mRNA and protein expression of vascular endotheli-al growth factor(VEGF),cluster of differentiation antigens 31(CD31),von Willebrand factor(vWF),collagenⅣ,and laminin(LN)were detected by qRT-PCR and ELISA,and the expression of nitric oxide(NO)was detec-ted by fluorescent probe,scanning electron microscopy detected the alteration of the window holes on the surface of human hepatic sinusoidal endothelial cells,angiogenesis assay was performed to observe the neovascularization of each group,and dual luciferase reporter gene assay was performed to validate the targeting relationship between miR-125b and VEGF.Results qRT-PCR and ELISA showed that compared with the negative control group,the mRNA and protein expressions of VEGF,CD31,vWF,Collagen Ⅳ,and LN significantly decreased after miR-125b mimic transfection(P＜0.05),while the mRNA and protein expressions of VEGF,CD31,vWF,CollagenⅣ,and LN were significantly increased after transfection with miR-125 b mimics(P＜0.05);fluorescent probe detection showed that compared with the negative control group,the average fluorescence of intensity expression NO decreased significantly(P＜0.05),while the average fluorescence intensity expression of NO increased significant-ly after miR-125b inhibitor transfection(P＜0.05);the number of fenestrations on the surface of human liver sinu-soidal endothelial cells significantly increased after miR-125b mimic transfection(P＜0.05),while the number of fenestrations on the surface of human liver sinusoidal endothelial cells decreased significantly after miR-125 b inhibi-tor transfection(P＜0.05);angiogenesis assay showed that compared with the negative control group,the number of angiogenesis significantly decreased after miR-125b mimic transfection(P＜0.05),while the number of angio-genesis significantly increased after miR-125b inhibitor transfection(P＜0.05);dual luciferase reporter gene assay showed that compared with negative control group,the expression of relative fluorescence intensity after transfection of miR-125b mimics in VEGF wild-typ significantly decreased(P＜0.05),while the expression of relative fluores-cence intensity after transfection of miR-125b mimics in VEGF mutant significantly decreased(P＞0.05).Con-clusion miR-125b can inhibit liver angiogenesis and thus play an anti-fibrosis role,which can provide a new ref-erence for the prevention and treatment of chronic liver disease and the development of new drugs.

Objective:To investigate the correlation of blood pressure variability within 24 h after thrombolysis with symptomatic intracerebral hemorrhage (sICH) and 90 d outcome in patients with acute ischemic stroke.Methods:Patients with acute ischemic stroke treated with recombinant tissue plasminogen activator in the Department of Neurology, Jinshan Branch, Shanghai Sixth People's Hospital from January 2017 to May 2019 were enrolled prospectively. The baseline data of the patients were collected. The patients were divided into sICH group and non-sICH group according to the changes of head CT and the National Institutes of Health Stroke Scale (NIHSS) score after thrombolysis. At 90 d after thrombolysis, the modified Rankin scale was used to evaluate the outcomes, and the patients were divided into a good outcome group (0-2) and a poor outcome group (3-6). The blood pressure within 24 h after thrombolysis was monitored and the parameters related to blood pressure variability in 5 time periods (0-2 h, 2-6 h, 6-12 h, 12-18 h, and 18-24 h) were calculated, including systolic blood pressure (SBP) and diastolic blood pressure (DBP) maximum (max), minimum (min), maximum and minimum difference (max-min) and mean (mean). The differences between the adjacent blood pressures were calculated, the standard deviation (SD), successive variation (SV), rise successive variability (SVrise), drop successive variability (SVdrop), the maximum squared difference in blood pressure rise (SVrisemax), the maximum squared difference in blood pressure drop (SVdropmax) were calculated and recorded, respectively. Multivariate logistic regression analysis was used to evaluate the effect of various blood pressure variability parameters on sICH and the outcomes after intravenous thrombolysis. Results:A total of 112 patients receiving intravenous thrombolysis were included in the study. Their median age was 71 years (range, 38-92 years), 66 were males (58.9%); median baseline NIHSS score was 10. Seventeen patients (15.2%) developed hemorrhagic transformation, 10 of them (8.9%) were sICH. The 90-d follow-up showed that 73 patients (65.2%) had a good outcome, 39 (34.8%) had a poor outcome and 7 of them (6.3%) died. There were significant differences in hypertension ( P=0.029), ischemic heart disease ( P=0.012), total cholesterol ( P=0.033), baseline NIHSS score ( P=0.003) between the sICH group and the non-sICH group. There were significant differences in age ( P=0.025), gender ( P=0.005), atrial fibrillation ( P=0.003), etiologic classification of stroke ( P=0.003), baseline NIHSS score ( P<0.001) and sICH ( P=0.003) between the poor outcome group and the good outcome group. In addition, there were significant differences in multiple blood pressure variability parameters among the above groups (all P<0.05). Multivariate logistic regression analysis showed that DBP SVdropmax, 6-12 h DBP SV, 12-18 h DBP SV, 6-12 h DBP SVdrop, 12-18 h DBP SVdrop were the independent risk factors for sICH after intravenous thrombolysis (all P<0.05); 2-6 h SBP SV, 2-6 h SBP SVrise, 2-6 h SBP SVdrop, 2-6 h DBP SV, 2-6 h DBP SVrise and 2-6 h DBP SVdrop were the independent risk factors for poor outcome after intravenous thrombolysis (all P<0.05). Conclusions:Early blood pressure and some blood pressure variability parameters are closely related to sICH and outcomes after intravenous thrombolysis in acute ischemic stroke. Closely monitoring of blood pressure and its variability can help clinical management and outcome prediction after intravenous thrombolysis.

Objective To systematically evaluate the correlation between sodium-glucose co-tran-sporter 2(SGLT2)inhibitors and fracture risk in type 2 diabetes mellitus(T2DM)patients. Methods The related databases were searched. The randomized controlled trials(RCTs)which the outcome index included fracture in T2DM patients treated with SGLT2 inhibitors from the inception to August 2017 were enrolled into the study. The documents were selected according to the inclusion and exclusion criteria. After the data extraction and evaluation of methodological quality of RCTs,Meta-analysis was conducted using Rev Man 5.3 software. Results A total of 12 RCTs involving 28 181 patients were entered,including 17 747 patients in the test group(SGLT2 inhibitors)and 10 434 in the control group. The drugs used in the test group were canagliflozin(7 RCTs)and empagliflozin(5 RCTs). The drugs used in the control group were non-SGLT2 inhibitors including metformin,glimetazide and/or placebo. The results of Meta-analysis showed that the incidence of fractures in the test group was significantly higher than that in the control group[5.05%(897/17 747)vs. 4.40%(459/10 434),RR=1.27,95%CI:1.14-1.42,P<0.01]. Subgroup analysis showed that the incidence of fractures in the canagliflozin group was significantly higher than that in the control group[6.21%(679/10 938)vs. 5.28%(365/6 913),RR=1.31,95%CI:1.15-1.48,P<0.01]. There were no significant differences in the incidence of fractures between the empagliflozin group and the control group[3.20%(218/6 809)vs. 2.67%(94/3 521),RR=1.44,95%CI:0.35-5.90, P=0.61]. Conclusions Canagliflozin(a kind of SGLT2 inhibitors)can increase the incidence of fractures. It is suggested that the risk assessment should be done before medication for the benefit of patients.

Objective To explore the effects of perinatal infection on retinopathy of prematurity (ROP).Methods A retrospective cohort study was performed to analyzed the clinical data of 238 preterm infants at gestational age ≤32 weeks who were delivered in Guangdong Women and Children Hospital from November 2014 to October 2015 and ROP screening examinations.Observation was not terminated until they were 45 weeks of corrected gestational age.Mild ROP was defined as having stage 1 or stage 2 ROP in zone Ⅱ or Ⅲ without additional disease,and severe ROP was defined as stage 3 or higher,any ROP in zone Ⅰ,prethreshold/threshold,with additional disease,and aggressive posterior retinopathy of prematurity (AP-ROP).Medical records of eligible preterm infants were retrospectively reviewed and analyzed.Occurrences of ROP,severe ROP,and clinically significant ROP requiring surgical treatment were assessed.Results The mean gestational age of the cohort was (30.10 ± 1.34) weeks (25.29-32.00 weeks) and the mean birth weight was (1 373 ± 272) g(720 ～2 330 g).ROP was diagnosed in 76 of 238 infants (31.9％),including 39 cases with mild ROP (16.4％) and 37 cases with severe ROP (15.5％).Surgical treatment was performed on 22 infants (9.2％).In the patients with ROP,the time to develop ROP from birth was (35.16 ± 14.26) d and the mean time of its most serious stage was (44.62 ± 18.99) d.In 22 patients with ROP who required surgical treatment,the time of surgical treatment was (50.27 ± 17.24) d.In univariate analysis,maternal perinatal infection disease was found to be associated with ROP occurrence (x2 =7.891,P =0.005) and ROP progression requiring surgical treatment (x2 =4.494,P =0.034).Small gestational age,low birth weight and long-term oxygen therapy were found to be asso ciated with ROP occurrence and severe ROP (gestational age:t =-5.803,P ＜ 0.001;t =-5.290,P ＜ 0.001;t =-4.150,P ＜ 0.001;birth weight:t =-4.942,P ＜ 0.001;t =-4.058,P ＜ 0.001;t =-3.126,P =0.002;the duration of oxygen therapy:t =2.351,P =0.020;t =2.473,P =0.018).Apgar scores ≤ 7 at 1 min and 5 min were found to be associated with severe ROP (x2 =4.803,P =0.028).Neonatal sepsis and neonatal fungal infection were found to be associated with ROP occurrence (x2 =6.071,P =0.014;x2 =4.070,P =0.044).Neonatal fungal infection was also found to be associated with severe ROP (x2 =5.479,P =0.019).Multivariate regression analysis indicated that maternal perinatal infection disease was associated with an increased risk of ROP and ROP progression requiring surgical treatment (OR =2.837,P =0.023;OR =4.087,P =0.012).Maternal preeclampsia was also associated with an increased risk of ROP (OR =2.506,P =0.040).Gestational age was an important risk factor for the development of ROP.The smaller the gestational age was,the higher the rate of occurring ROP and severe ROP (OR =0.518,0.508,0.520,all P ＜ 0.001).Conclusions Both fetal and neonatal exposure to infection appear to contribute to the increase of ROP risk in the preterm infants at gestational age ≤ 32 weeks.Maternal perinatal infection disease and maternal preeclampsia were independently associated with ROP occurrence and ROP progression in the preterm infants at gestational age ≤32 weeks.
