This paper summarizes Professor YAN Huimin's clinical experience in the staged treatment of pediatric IgA vasculitis. It is believed that the pathogenesis in the acute stage is characterized by fire and heat entering the blood and damaging the collaterals， and the treatment should focus on clearing heat and stopping bleeding， using the self-formulated Qingzi Liangxue Formulation （青紫凉血方）. In the remission stage， the pathogenesis is qi rebellion leading to blood extravasation. The treatment principle is to regulate qi and stabilize blood， using the self-formulated Heqi Ningxue Formulation （和气宁血方）. During the protracted stage， the pathogenesis is latent pathogenic factors due to yin deficiency， and the treatment should aim to nourish the collaterals and strengthen the root， with the self-formulated Yangluo Guben Formulation （养络固本方）. Meanwhile， the method of promoting blood stasis resolution is consistently applied throughout the entire treatment process.

Objective:To investigate the reliability and accuracy of a semi-quantitative evaluation method for assessing the severity of pharyngeal delay by fiberoptic laryngoscopy.Method:Fifty-seven fiberoptic endoscopic evaluation of swallowing(FEES)videos and the corresponding 57 video fluoroscopic swallowing study(VFSS)videos were reviewed and analyzed independently by two investi-gators.The semiquantitative evaluation method of pharyngeal delay in the expert consensus on assessment and treatment of swallowing disorders in China(2017 version)was used to rate fiberoptic endoscopic evaluation of swallowing videos.The pharyngeal delay time(PDT)was calculated by the corresponding video fluoroscop-ic swallowing study videos.The intraclass correlation coefficient(ICC)was used as an indicator to verify the consistency of the retention position of the bolus on set of swallowing in VFSS and FEES.The Kruskal-Wal-lis H test was used to compare the difference in PDT between the different classes.Spearman's rank correla-tion analysis was used to test the correlation between the retention position of bolus on set of swallowing and aspiration under VFSS and FEES.The correlation was statistically significant at P<0.05.Result:The consistency index ICC for determining retention position of bolus on set of swallowing in VFSS and FEES was 0.707(P<0.001)indicating moderate agreement.Therefore,the PDT measured by VFSS corre-sponding to different grades of pharyngeal delay in FEES could be compared between groups.The results showed that:between normal and mild groups(P=0.003),between normal and moderate groups(P<0.0001),and between the normal and severe groups(P<0.0001).However,there were no significant differences be-tween the mild and moderate groups(P=1.000),the mild and severe groups(P=0.141),and the moderate and severe groups(P=1.000).The correlation between retention position of bolus on set of swallowing and as-piration was not significant(P=0.642 under VFSS and P=0.920 under FEES).Conclusion:The semi-quantitative evaluation scale of pharyngeal delay under FEES has limited ability to re-flect the severity of swallowing delay,and the degree of differentiation between grades is low,only distin-guishing the normal group from the abnormal group.Thus,it is recommended that this evaluation scale be ad-justed to three levels:normal level:the head of the bolus reaches the root of the tongue and swallowing is initiated;abnormal level:the bolus reaches a site below the tongue base and lingers for a certain period of time before swallowing is initiated.No swallowing level:the bolus lingered anywhere below the tongue base and no swallowing initiation was observed.

Objective:To systematically integrate the lived experiences of women regarding decision-making participation and informed choice during intrapartum care, providing evidence-based guidance for improving obstetric healthcare management and service quality, and enhancing women′s childbirth experiences.Methods:Computerized searches were conducted in PubMed, Web of Science, Cochrane Library, CINAHL, PsycINFO, Scopus, ProQuest, China National Knowledge Infrastructure, Wanfang, Chinese Scientific Journals Database, and China Biology Medicine disc for qualitative studies on women′s experiences of shared decision-making participation and informed choice during childbirth. The search period spanned from January 1, 1997 to August 15, 2024. Literature quality was assessed using the Joanna Briggs Institute Critical Appraisal Checklist for Qualitative Research. Meta-aggregation was employed to synthesize findings by grouping similar results into new categories and integrating outcomes based on logical relationships between categories.Results:Eleven studies were included, yielding 47 key findings synthesized into 10 categories and further integrated into four overarching themes: complex emotional experiences in intrapartum decision-making participation; Diverse coping strategies for intrapartum decision-making participation; multiple stressors faced during intrapartum decision-making participation; multifaceted support needs in intrapartum decision-making participation.Conclusions:Midwives and healthcare providers should deliver education on shared decision-making and informed choice during the third trimester. Continuous attention to maternal emotional shifts regarding decision-making participation and informed choice during labor is essential. Comprehensive decision support, effective intrapartum communication, and initiatives to promote maternal autonomy through empowerment and capacity building should be prioritized.

Objective:To evaluate the impact of bladder volume on dosimetric parameters of clinical target volume (CTV) and organs at risk (OAR) of intensity modulated proton therapy (IMPT) for localized prostate cancer during the treatment planning and daily treatment.Methods:Clinical data of 25 patients with localized prostate cancer admitted to Ruijin Hospital affiliated to Shanghai Jiao Tong University School of Medicine from November 2021 to June 2022 and enrolled in the "Proton Therapy System" (SAPT-PS-01) registered clinical trial were retrospectively analyzed. All patients were male and the median age was 72 years old. A total of 30 sets of IMPT plans were obtained. Based on the planning CT (30 sets) and weekly verification CT during treatment (172 sets), bladder volume, CTV and OAR dose parameters were collected. Spearman correlation analysis was used to evaluate the correlation between bladder volume in CT and the dosimetric parameters of CTV and OAR during IMPT plans, and Wilcoxon-Mann-Whitney test was adopted to compare the dosimetric parameters of CTV and OAR among different bladder volume change groups.Results:The V 95% of CTV1 and CTV2 were both 100.0%±0.0% in IMPT plans. Bladder volume was significantly negatively correlated with D mean, V 70 Gy(RBE), V 60 Gy(RBE), V 50 Gy(RBE), V 40 Gy(RBE) of the bladder ( P<0.001, 0.003, <0.001, <0.001,<0.001), and D mean, V 50 Gy(RBE) of the small intestine (both P<0.001). During treatment, bladder D mean, V 70 Gy(RBE), V 60 Gy(RBE), V 50 Gy(RBE), V 40 Gy(RBE)( P<0.001, 0.001, <0.001, <0.001, <0.001), rectal D mean, V 50 Gy(RBE), V 40 Gy(RBE) (all P<0.001), small intestine D mean, V 50 Gy (RBE) (both P<0.001) of patients with bladder volume increase >20% compared to baseline were significantly decreased compared to those in IMPT plans. But CTV1 V 100%, and CTV2 V 95% were significantly decreased too( P=0.029, 0.020). In the bladder volume decreased>20% patients, the D mean, V 70 Gy(RBE), V 60 Gy(RBE), V 50 Gy(RBE), V 40 Gy(RBE) of the bladder were significantly increased compared to those in IMPT plans (all P<0.001). However, a bladder volume reduction of ≤20% and increase of ≤20% from baseline had no significant impact on CTV and OAR dosimetric parameters during treatment. Conclusions:For patients with localized prostate cancer undergoing proton therapy, a certain bladder volume should be ensured during planning CT scans. During the daily treatment, the bladder volume should be maintained between 80%-120% of the baseline level to ensure CTV coverage and good dose sparing to OAR.

In various types of inspections and self-inspections, it was found that compliance and rationalization in diagnosis and charging were the more common problems in hospital, leading to refusal of medical insurance payment. In 2022, the failure mode and effect analysis was conducted in a Grade-A tertiary hospital in Jinhua to identify the high-risk points in the process of diagnosis and treatment and charging, and building six major information technology transformation scenarios and formulating specific transformation measures, to avoid or reduce the refusal of medical insurance payment in advance. Through the digital transformation of medical insurance supervision system, a whole process intelligent supervision has been implemented, including pre event review, mid event reminder and intelligent correction, and post event big data precise analysis. It promoted compliant diagnosis and treatment of medical personnel and accurate charging, which could provide reference for other medical institutions to use medical insurance funds reasonably.

ObjectiveTo provide technical support for the molecular surveillance of pathogenic bacteria strains carrying mobile colistin resistance-1 （mcr⁃1） gene isolate from inlet of wastewater treatment plants （WWTP）. MethodsThe Enterobacteriaceae strains carrying mcr⁃1 resistance gene isolate from inlet of WWTP during April 1 to June 30， 2023 in Shanghai were cultured on blood-rich and SS culture medium and were identified using a mass spectrometry analyzer. The mcr⁃1 gene and copy number were detected by real-time fluorescence quantitative PCR. Drug susceptibility test was performed by microbroth dilution method. The copy numbers of Escherichia coli carrying mcr⁃1 gene isolated from wastewater and human fecel were statistically analyzed by SPSS 25.0. ResultsA total of 14 strains carrying the mcr⁃1 gene were isolated from 49 WWTP samples， and the positive isolation rate was 28.6%， including 12 non-diarrheal E. coli strains and 2 Klebsiella pneumoniae strains. The drug susceptibility results showed that all 14 strains were multi-drug resistant bacteria. They were all sensitive to imipenem and tigecycline， but were ampicillin- and cefazolin-resistant. There was no significant difference in the copy number between human-sourced diarrheal E. coli and wastewater-sourced non-diarrheal E. coli （t=0.647， P>0.05）. ConclusionThe isolation and identification of strains carrying the mcr⁃1 gene from inlet of WWTP samples were firstly established in Shanghai. The multi-drug resistance among the isolated strains is severe. To effectively prevent and control the spread of colistin-resistant bacteria， more attention should be paid to the surveillance of mcr⁃1 gene.

Objective:To investigate the influence of prenatal stressful life event (SLE) exposure on child emotional and behavioral problem at age 2-6 years and identify the most risk exposure period.Methods:A total of 2 524 mother-child pairs were selected from Shanghai Maternal-Child Pairs Cohort based on pregnant women form 2016 to 2018 in Shanghai. Prenatal SLE exposure was assessed by Life Events Scale for Pregnant Women Questionnaire during the first and third trimester of pregnancy. Child emotional and behavioral problem was evaluated by Strengths and Difficulties Questionnaire at age 2-6 years. Multivariate binary logistic regression model and generalized estimating equation were conducted to quantify the association between prenatal SLE exposure and child emotional and behavioral problem at age 2-6 years, and identify the pregnancy period with strongest adverse effect.Results:The 2 524 mother-child pairs were divided into 4 groups: group with consistent low exposure to SLE (61.8%), group with high exposure to SLE in the first trimester (13.2%), group with high exposure to SLE in the third trimester (13.2%) and group with consistent high exposure to SLE (11.8%). The detection rates of emotional problem, hyperactivity, peer interaction problem and total difficulty score in children aged 3-6 years were highest in the group with consistent high exposure to SLE. Generalized estimating equation analysis showed that after controlling the confounding factors, compared with the consistent low exposure group, the children in the group with high exposure to SLE in the first trimester had significant increased risk for conduct problem at age 2-6 years (a OR=1.41, 95% CI:1.07-1.87). The children in the group with consistent high exposure to SLE were at increased risk for emotional problem, peer interaction problem, and high total difficulty score with the a OR of 1.41 (95% CI: 1.09-1.83), 1.46 (95% CI: 1.15-1.86) and 1.51(95% CI: 1.17-1.93). Conclusion:These findings indicated that prenatal exposure to SLE have adverse effect on child emotional and behavioral problem at age 2-6 years, especially the exposure in the first trimester.

The ChatGPT, a lite and conversational variant of Generative Pretrained Transformer 4 (GPT-4) developed by OpenAI, is one of the milestone Large Language Models (LLMs) with billions of parameters. LLMs have stirred up much interest among researchers and practitioners in their impressive skills in natural language processing tasks, which profoundly impact various fields. This paper mainly discusses the future applications of LLMs in dentistry. We introduce two primary LLM deployment methods in dentistry, including automated dental diagnosis and cross-modal dental diagnosis, and examine their potential applications. Especially, equipped with a cross-modal encoder, a single LLM can manage multi-source data and conduct advanced natural language reasoning to perform complex clinical operations. We also present cases to demonstrate the potential of a fully automatic Multi-Modal LLM AI system for dentistry clinical application. While LLMs offer significant potential benefits, the challenges, such as data privacy, data quality, and model bias, need further study. Overall, LLMs have the potential to revolutionize dental diagnosis and treatment, which indicates a promising avenue for clinical application and research in dentistry.
