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 effects of acupuncture on the neurotransmitter levels and gut microbiota in a mouse model of Tourette syndrome (TS). METHODS: Thirty-six male C57/BL6 mice were randomly divided into 4 groups using a random number table method: 3,3'-iminodipropionitrile (IDPN) group, control group, acupuncture group, and tiapride group, with 9 mice in each group. In the IDPN group, acupuncture group, and tiapride group, mice received daily intraperitoneal injections of IDPN (300 mg/kg body weight) for 7 consecutive days to induce stereotyped behaviors. Subsequently, in the acupuncture intervention group, standardized acupuncture treatment was administered for 14 consecutive days to IDPN-induced TS model mice. The selected acupoints included Baihui (DU 20), Yintang (DU 29), Waiguan (SJ 5), and Zulinqi (GB 41). In the tiapride group, mice were administered tiapride (50 mg/kg body weight) via oral gavage daily for 14 consecutive days. The control group, IDPN group, and acupuncture group received the same volume of saline orally for 14 consecutive days. Stereotypic behaviors were quantified through behavioral assessments. Neurotransmitter levels, including dopamine (DA), glutamate (Glu), and aspartate (ASP) in striatal tissue were measured using enzyme-linked immunosorbent assay. Dopamine transporter (DAT) expression levels were additionally quantified through quantitative polymerase chain reaction (qPCR). Gut microbial composition was analyzed through 16S ribosomal RNA gene sequencing, while metabolic profiling was conducted using liquid chromatography-mass spectrometry (LC-MS). RESULTS: Acupuncture administration significantly attenuated stereotypic behaviors, concurrently reducing striatal levels of DA, Glu and ASP concentrations while upregulating DAT expression compared with untreated TS controls (P<0.05 or P<0.01). Comparative analysis identified significant differences in Muribaculaceae (P=0.001), Oscillospiraceae (P=0.049), Desulfovibrionaceae (P=0.001), and Marinifilaceae (P=0.014) following acupuncture intervention. Metabolomic profiling revealed alterations in 7 metabolites and 18 metabolic pathways when compared to the TS mice, which involved various amino acid metabolisms associated with DA, Glu, and ASP. CONCLUSIONS Acupuncture demonstrates significant modulatory effects on both central neurotransmitter systems and gut microbial ecology, thereby highlighting its dual therapeutic potential for TS management through gut-brain axis regulation.

A fluorescence endoscopic laser confocal microscope(FELCM) was used to direct the injection of sinomenine solid lipid nanoparticles(Sin-SLN) into the joint, and the in vitro effectiveness of Sin-SLN in the treatment of rheumatoid arthritis(RA) was evaluated. Sin-SLN was prepared with the emulsion evaporation-low temperature curing method. The Sin-SLN prepared under the optimal conditions showed the encapsulation efficiency of 64.79%±3.12%, the drug loading of 3.84%±0.28%, the average particle size of(215.27±4.21) nm, and the Zeta potential of(-32.67±0.84) mV. Moreover, the Sin-SLN demonstrated good stability after sto-rage for 30 days. The rabbit model of RA was established by the subcutaneous injection of ovalbumin and complete Freund's adjuvant. Five groups were designed, including a control group, a model group, a Sin(1.5 mg·kg~(-1)) group, a Sin-SLN(1.5 mg·kg~(-1)) group, and a dexamethasone(positive drug, 1.0 mg·kg~(-1), ig) group. The control group and the model group only received puncture treatment without drug injection. After drug administration, the local skin temperature and knee joint diameter were monitored every day. The knee joint diameter and the local skin temperature were lower in the drug administration groups than in the model group(P<0.05, P<0.01). FELCM recorded the morphological alterations of the cartilage of knee joint. The Sin-SLN group showed compact tissue structure and smooth surface of the cartilage. Enzyme-linked immunosorbent assay(ELISA) was employed to determine the serum le-vels of interleukin-1(IL-1) and tumor necrosis factor-α(TNF-α). The findings revealed that the Sin-SLN group had lower IL-1 and TNF-α levels than the model group(P<0.05, P<0.01). Hematoxylin-eosin(HE) staining was employed to reveal the pathological changes of the synovial tissue, which were significantly mitigated in the Sin-SLN group. The prepared Sin-SLN had uniform particle size and high stability. Through joint injection administration, a drug reservoir was formed. Sin-SLN effectively alleviate joint swelling and cartilage damage of rabbit, down-regulated the expression of inflammatory cytokines, and inhibited the epithelial proliferation and inflammatory cell infiltration of the synovial tissue, demonstrating the efficacy in treating RA.

COVID-19 is caused by a novel coronavirus-severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2), which has being spreading around the world, posing a serious threat to human health and lives. Neutralizing antibodies and small molecule inhibitors for virus replication cycle are the main antiviral treatment for novel coronavirus recommended in China. To further promote the rational use of antiviral therapy in clinical practice, the National Center for Infectious Diseases (Beijing Ditan Hospital Capital Medical University and the First Affiliated Hospital, Zhejiang University School of Medicine) invited experts in fields of infectious diseases, respiratory and intensive care to develop an Expert Consensus on Antiviral Therapy of COVID-19 based on the Diagnosis and Treatment Guideline for COVID-19 ( trial version 10) and experiences in the diagnosis and treatment of COVID-19 in China. The consensus is concise, practical and highly operable, hopefully it would improve the understanding of antiviral therapy for clinicians and provide suggestions for standardized medication in treatment of COVID-19.

Rheumatoid arthritis(RA) is a widely prevalent autoimmune inflammatory disease that severely affects patients' quality of life. Currently, conventional formulations against RA have several limitations, such as nonspecificity, poor efficacy, large drug dosages, frequent administration, and systemic side effects. Nanotechnology-based drug delivery systems have emerged as a promising stra-tegy for the diagnosis and treatment of RA since nanotechnology can overcome the limitations of traditional treatments and simplify the complexity of the disease. These systems enable targeted delivery of anti-inflammatory drugs to the inflamed areas through active and passive targeting, achieving specificity to the joints, overcoming the need for increased dosage and administration frequency, and reducing associated adverse reactions. This article aimed to review nanocarrier-based drug delivery systems in the field of RA and elucidate how nanosystems can be utilized to deliver therapeutic drugs to inflamed joints for controlling RA progression. By discussing the current issues and challenges faced by nanodrug delivery systems and highlighting the urgent need for solutions, this article offers theoretical support for further research on nanotechnology-based co-delivery systems in the future.

Objective:To understand the incidence and clinical characteristics of dopamine agonist(DA) therapy-related impulse control disorders(ICDs) in prolactinoma patients.Methods:Outpatients diagnosed with prolactinoma from the Department of Endocrinology in Huashan Hospital from December 2019 to June 2020 were consecutively included and clinical data were collected. Impulse control disorders were screened with Questionnaire for Impulsive-Compulsive Disorders in Parkinson′s Disease(QUIP). Barratt Impulsiveness Scale 11(BIS-11) was used to evaluate personality construct of impulsiveness from three sub-factors . Health related quality of life was evaluated by the MOS 36-Item Short Form Health Survey(SF-36).Results:Among the 111 cases included, 40 were male and 53 were female, with an average age of(34.74±9.05) years and an average disease duration of(66.69±50.70) months. The initial prolactin level was 147.25(89.97, 470) ng/mL and the percentage of macroadenoma was 46.8%. Ninety cases received DA while 21 cases didn′t. According to the QUIP, any ICD was screened positive in 22 cases(24.7%) in the DA group and 3 cases(14.3%) in the untreated group. The attention impulsiveness scores of BIS-11 in the DA group were higher than the untreated group(23.32±3.67 vs 21.71±2.55, P=0.022). Among the ICDs positive cases in the DA group, the most common disorders were pathological gambling(40.6%) and hypersexuality(40.6%). Compared with the negative group, the non-planning impulsiveness scores of BIS-11 in the positive group were higher, while the scores of social function(69.32±24.62 vs 83.08±17.11, P=0.021), role emotional(50.00±45.72 vs 71.10±40.68, P=0.043) and mental health(55.27±22.75 vs 64.59±17.53, P=0.048) in SF-36 scale were lower in the positive group. Besides, the percentage of male(68.2% vs 38.2%, P=0.014) and initial prolactin level[470.00(130.00, 3 770.00) vs 140.29(79.50, 465.59) ng/mL, P=0.028] in the positive group were higher. Male was an independent risk factor of the presence of ICDs( OR=3.46, 95% CI 1.24-9.61, P=0.017). No significant difference was found in the type of drugs, duration, maximal or cumulative dose of treatment with DA between the two groups. Conclusion:Impulse control disorders may occur in prolactinoma patients receiving DA treatment and affect the quality of life. Endocrinologists should screen impulse control disorders in this patient set.

OBJECTIVES: To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China. METHODS: A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups. RESULTS: Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05). CONCLUSIONS There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

TaqMan low-density arrays (TLDA) real-time PCR was performed to simultaneously detect multiple respiratory pathogens. The HN gene was amplified using nested RT-PCR and sequenced, followed by phylogenetic analysis for those HPIV3 positive samples.Results:Of the 17 specimens, 10 were HPIV3 positive by TLDA Real-time PCR, and were accompanied by conditional pathogen infection, consequently, amplification result ed in 7 complete HN sequences. Phylogenetic analysis showed that the infected HPIV3 virus of the outbreak belonged to HPIV subtype C3a. All the 7 strains detected in this study belonged to subbranch C3a.1 evolutionary branch, with a nucleotide homology of 99.9%, a nucleotide homology of 94.56 with the prototype strain Wash/47885/57 and 99.5% with the most phylogenetically close strain of ZJ/11-s-165/KP690785/CHN/11.Conclusions:The HPIV3 virus caused the acute respiratory tract infection outbreak in Shenyang in 2020 and HPIV subtype C3a1 was detected firstly in Northeast China.

Objective:To establish the acute symptomatic osteoporotic thoracolumbar fracture (ASOTLF) classification system, and to examine the reliability and evaluate the effect of clinical application.Methods:A retrospective case series study was conducted to analyze the clinical data of 1 293 patients with osteoporotic thoracolumbar fracture(OTLF) admitted to Honghui Hospital from January 2016 to December 2018. There were 514 males and 779 females, aged 57-90 years [(71.4±6.3)years]. The T value of bone mass density was -5.0--2.5 SD [(-3.1±-0.4)SD]. According to the clinical symptoms a and fracture morphology, OTLF was divided into 4 types, namely type I(I occult fracture), type II(compressed fracture), type III (burst fracture) and type IV(unstable fracture). The type II was subdivided into three subtypes (type IIA, IIB, IIC), and the Type III into two subtypes (type IIIA, IIIB). of all patients, 75 patients (5.8%) were with type I, 500 (38.7%) with type II A, 134 (10.4%) with type IIB, 97 (7.5%) with type IIC, 442 (34.2%) with type IIIA, 27(2.1%) with type IIIB and 18 (1.4%) with type IV. After testing the validity of the classification, different treatment methods were utilized according to the classification, including percutaneous vertebroplasty (PVP) for Type I, PVP after postural reduction for Type II, percutaneous kyphoplasty (PKP) for Type IIIA, posterior reduction and decompression, bone graft fusion and bone cement-augmented screw fixation for Type IIIB, and posterior reduction, bone graft fusion and bone cement-augmented screw fixation for Type IV. The visual analog score (VAS), Oswestry disability index (ODI), Frankel grade of spinal cord injury, local Cobb Angle, and vertebral body angle (vertebral body angle) were recorded in all patients and in each type of patients before surgery, at 1 month after surgery and at the last follow-up. The neurological function recovery and complications were also recorded.Results:The patients were followed up for 24-43 months [(29.9±5.1)months]. A total of 3 000 assessments in two rounds were conducted by three observers. The overall κ value of inter-observer credibility was 0.83, and the overall κ value of intra-observer credibility was 0.88. The VAS and ODI of all patients were (5.8±0.7)points and 72.5±6.6 before surgery, (1.8±0.6)points and 25.0±6.3 at 1 month after surgery, and (1.5±0.6)points and 19.5±6.2 at the last follow-up, respectively (all P<0.05). The Cobb angle and vertebral body angle of all patients were (13.0±9.1)° and (8.0±4.6)° before surgery, (7.9±5.2)° and (4.6±2.9)° at 1 month after surgery, and (9.1±6.0)° and (5.8±3.0)° at the last follow-up, respectively (all P<0.05). At the last follow-up, VAS, ODI, Cobb Angle and VBA of each type of patients were significantly improved compared with those before surgery (all P<0.05). The spinal cord compression symptoms were found 1 patient with type IV and 5 patients with type IIIB preoperatively. At the last follow-up, neurological function improved from grade C to grade E in 1 patient and from grade D to grade E in 5 patients ( P<0.05). The lower limb radiation pain or numbness in 3 patients with type IV and 22 patients with type III preoperatively were fully recovered after surgical treatment at the last follow-up except for three patients. Conclusions:The ASOTLF classification is established and has high consistency and reliability. The classification-oriented treatment strategy has achieved a relatively satisfactory effect, indicating that the classification has a certain guiding significance for treatment of OTLF.
