[Objective] To explore the clinical features of IgG4-related urinary diseases so as to provide reference for the diagnosis and treatment of such diseases. [Methods] The clinical data of 4 cases of IgG4-related urinary system diseases diagnosed and treated in Xijing Hospital of Air Force Medical University during Aug.2019 and Dec.2023 were retrospectively collected.Here, we report on the diagnosis and treatment of these patients, analysing their symptoms, serology, imaging and pathology as well as their treatment and outcomes. [Results] The patients included 2 male and 2 female.The lesions were involved with the retroperitoneum and urinary system.Three patients had symptoms of lumbar pain.The imaging manifestations were complex, including retroperitoneal mass involving urinary system organs in 2 cases, tabdense shadow of the right kidney in 1 case, and simple cystic mass of kidney in 1 case.Serum IgG4 value was not detected before surgery.All patients underwent radical surgical treatment.Postoperative pathology showed fibrous tissue hyperplasia with a large number of plasma cells, lymphocytes, a few neutrophil infiltrates, and lymphoid follicles and obliterated vasculitis in some specimens.The number of IgG4⁺ plasma cells was more than 10 in all tissues under high power microscope.After surgery, 3 patients had symptoms improved, and serum IgG4 value was within the normal range; 1 patient (patem 3) had elevated IgG4 value during follow-up, received subsequent hormone therapy, and the serum IgG 4 level remained stable. [Conclusion] The symptoms of IgG4-related diseases involving the urinary system are non-specific, and the imaging findings are various, easily confused with other diseases.Early detection of serum IgG4 and biopsy pathology can help clinicians make correct diagnosis in the early stage.

By analyzing the current application of multi-modal data in the diagnosis of gastric "inflammation-cancer" transformation， this study explored the feasibility and strategies for constructing a disease-syndrome integrated diagnosis and treatment system. Based on traditional Chinese medicine （TCM） phenomics， we proposed utilizing multi-modal data from literature research， cross-sectional studies， and cohort follow-ups， combined with artificial intelligence technology， to establish a multi-dimensional diagnostic and treatment index system. This approach aims to uncover the complex pathogenesis and transformation patterns of gastric "inflammation-cancer" progression. Additionally， by dynamically collecting TCM four-diagnostic information and modern medical diagnostic information through a long-term follow-up system， we developed three major modules including information extraction， multi-modal phenotypic modeling， and information output， to make it enable real-world clinical data-driven long-term follow-up and treatment of chronic atrophic gastritis. This system can provide technical support for clinical diagnosis， treatment evaluation， and research， while also offering insights and methods for intelligent TCM diagnosis.

ObjectiveTo evaluate the efficacy and safety of Xihuang Pill/Capsule （西黄丸/胶囊， XP/XC） as an adjuvant to radiotherapy and/or chemotherapy in the treatment of malignant digestive tract tumors. MethodsA systematic search was conducted in the China Biomedical Literature Database， China National Knowledge Infrastructure （CNKI）， Wanfang Data Knowledge Service Platform， VIP Database， PubMed， Web of Science， Embase， and Cochrane Library for randomized controlled trials （RCTs） published before March 6， 2024， regarding the use of XP/XC in clinical adjuvant treatment of malignant digestive tract tumors. The methodological quality of the included studies was assessed using the risk of bias assessment tool. RevMan 5.4 was used to perform a Meta-analysis on 1-year survival rate， 2-year survival rate， clinical efficacy， including objective response rate and disease control rate， Karnofsky Performance Status （KPS） score， immune markers （CD3⁺， CD4⁺， CD8⁺， and CD4⁺/CD8⁺ ratio）， and adverse event rates （incidence of gastrointestinal reactions and bone marrow suppression）. ResultsThirteen RCTs involving 962 patients were included， with 527 patients in the experimental group and 435 patients in the control group. Meta-analysis results showed that the experimental group had better outcomes than the control group in terms of 2-year survival rate ［RR = 0.49， 95% CI （0.31， 0.78）］， objective response rate ［RR = 0.68， 95% CI （0.60， 0.77）］， disease control rate ［RR = 0.85， 95% CI （0.80， 0.91）］， and immune markers CD3⁺ ［MD = -7.99， 95% CI （-9.12， -6.86）］， CD4⁺ ［MD = -5.42， 95% CI （-7.11， -3.74）］， and CD4⁺/CD8⁺ ratio ［MD = -0.26， 95% CI （-0.32， -0.20）］ （P＜0.05）. However， no statistically significant differences were found between the experimental and control groups in terms of 1-year survival rate ［RR = 0.91， 95% CI （0.73， 1.14）］， KPS ［MD = -3.73， 95% CI （-8.67， 1.21）］， CD8⁺ ［MD = -0.53， 95% CI （-1.45， 0.39）］， incidence of gastrointestinal reactions ［RR = 0.82， 95% CI （0.46， 1.46）］， and incidence of bone marrow suppression ［RR = 0.93， 95% CI （0.72， 1.20）］ （P＞0.05）. ConclusionCompared with radiotherapy/chemotherapy alone， the combination of XP/XC with radiotherapy/chemotherapy can effectively improve clinical efficacy and 2-year survival rate， enhance immune function， and achieve similar adverse event rates as radiotherapy/chemotherapy alone in patients with malignant digestive tract tumors.

Background A diverse cohort of patients and susceptible individuals congregate in healthcare facilities, where exposure to pathogenic microorganisms associated with respiratory infectious diseases constitutes a significant risk factor for cross-infection. Central air-conditioning ventilation systems improve some indoor environment indicators while exacerbating the risk of transmission of respiratory infectious diseases. Objective To investigate the distribution characteristics of microbial communities in the central air-conditioning ventilation systems of hospitals, providing a scientific basis for the selection of microbial indicators in hygiene standards for hospital central air-conditioning ventilation systems and for hospital risk early warning systems. Methods In October 2023, two central air-conditioning ventilation systems were selected from a Grade 3A hospital in Shanghai: one was an all-air air-conditioning system serving the waiting area on the ground floor, and the other was a fan coil plus fresh air system serving the outpatient area on the third floor. Samples from four different components of the ventilation systems—air outlets, filters, surface coolers, and condensate trays—were collected for high-throughput sequencing of the 16S rRNA gene to analyze bacterial communities. Alpha-diversity and beta-diversity analyses were performed to investigate the microbial community composition and diversity characteristics of the hospital central air-conditioning ventilation systems. Functional analysis was conducted to determine the relative abundance of bacterial functions in these systems.Results A total of 528 operational taxonomic units (OTUs) were identified, encompassing 20 bacterial phyla, 37 classes, 79 orders, 123 families, and 240 genera. The analysis revealed that the bacterial community was predominantly composed of Proteobacteria, Gemmatimonadates, Bacteroidetes, and Actinobacteria. The diversity analysis indicated that bacterial community richness and diversity were highest in the condensate trays, while no statistically significant differences (P > 0.05) were observed in the bacterial community composition among the air outlets, filters, and surface coolers. The functional analysis showed that the bacterial communities in the central air-conditioning ventilation systems primarily exhibited chemoheterotrophic, oxidative energy-dependent heterotrophic, and ureolytic functional characteristics. Conclusion The dominance of Proteobacteria suggests that this phylum exhibits strong adaptability in the central air-conditioning ventilation systems, possibly related to its ability to survive and reproduce under varying environmental conditions. The diversity analysis indicates that the condensate tray is a critical area for bacterial proliferation in the central air-conditioning ventilation systems. The similarity in environmental conditions among the air outlets, filters, and surface coolers result in similar bacterial community structures. The functional analysis reveals that the bacterial communities possess robust energy conversion and metabolic capabilities, potentially contributing to processes such as organic matter decomposition and nitrogen cycling within the central air-conditioning ventilation systems.

Misophonia is a psychophysiological and behavioral disorder characterized by an individual's low tolerance to specific sounds， leading to intense negative emotional experiences and physiological responses. Currently， there is no standardized and universally effective treatment for misophonia in clinical practice worldwide. This article reports the case of an 18-year-old male patient with misophonia who showed poor response to sertraline combined with exposure and response prevention therapy. Subsequently， the patient received 8 weeks of Morita therapy （once a week， 50 minutes per session）， with symptomatic improvement. By presenting this case， we explore the potential efficacy of Morita therapy in treating misophonia， aiming to provide a reference for its clinical management. ［Funded by Scientific Research Development Fund Project of Shandong Second Medical University （number， 2024FYM034）］

Objective: To explore the long term trend of forced vital capacity to weight index (FWI) among Chinese Han students aged 7-18 from 2000 to 2019, and to predict its changes over the next decade, so as to provide scientific evidences for targeted health interventions and school health policies. Methods: Based on the data of the five Chinese National Surveys on Students Constitution and Health conducted from 2000 to 2019, a total of 216 500, 233 565, 215 267, 214 256 and 212 632 Han students aged 7-18 were included, respectively. The long term trend of FWI among students was analyzed, and the GM (1,1) grey model was used to predict FWI changes over the next decade. Subgroup analyses were conducted by sex, age, and urban-rural residence. Results: The FWI levels of Chinese Han students aged 7-18 were (55.30±11.47)(47.43±11.92)(48.11±12.46)(48.75±12.81)(50.93±13.11)mL/kg in 2000, 2005, 2010, 2014, and 2019, respectively. The FWI of Chinese Han students showed a decreasing then increasing trend from 2000 to 2019, reaching the lowest point of approximately 47.03 mL/kg around 2006, and was projected to recover to 52.88 mL/kg by 2029. Boys had higher FWI for each year and the total level than girls from 2000 to 2019( t =72.58-304.66), and the decline between 2000 and 2005 was smaller in boys (13.1%) than in girls (15.4%). However, the gender gap gradually narrowed and was projected to reduce to 5.36 mL/kg by 2029. FWI increased with age, with the largest difference observed in 2014 between the 7-9 and 16-18 age groups (8.62 mL/kg). Before 2014, urban boys had slightly lower FWI than rural boys; the gap narrowed thereafter, and their FWI levels were expected to become similar by 2029. Urban girls generally had higher FWI than rural girls, and the urban-rural gap showed an increasing trend. By 2029, the largest difference was projected to occur in the 13-15 age group, reaching 7.74 mL/kg. Conclusions The FWI of Chinese Han students showed a trend of initial decline followed by a gradual increase from 2000 to 2019, with notable differences across sex, age, and urban-rural residence. Greater attention should be paid to the respiratory health of rural girls, and effective measures should be taken to reduce urban-rural disparities.

Objective　To analyze the clinical characteristics and prognostic factors for clinical cure in chronic hepatitis B virus (HBV) infected patients with pegylated interferon-α-2b (PEG-IFN-α-2b) based therapy. Methods　This is a retrospective study. Chronic HBV infected patients receiving PEG-IFN-α-2b therapy were enrolled in Yuncheng Central Hospital affiliated to Shanxi Medical University between August 2020 and November 2023. Treatment-naïve patients received PEG-IFN-α-2b monotherapy, while nucleoside (acid) analogs (NAs)-experienced patients received PEG-IFN-α-2b add-on therapy. The study endpoint was hepatitis B surface antigen (HBsAg) negative in accompany with HBV DNA below the detection limit (course of treatment < 48 weeks) or treatment for 48 weeks. The general characteristics, virological variables, blood routine test, and liver function of patients were collected at baseline and study endpoint. Student’s t test or Mann-Whitney U test was used for comparison. The prognostic factors of clinical cure were examined using univariate and multivariate stepwise logistic regression models. Results　A total of 61 chronic HBV infected patients were enrolled, including 39 males and 22 females. The age were (39.13±7.53) years. Twenty-one cases were treatment-naïve, while 40 patients were NAs-experienced. Nineteen cases were positive for HBV DNA at baseline. The baseline HBsAg levels were 211.30(50.93, 2 110.00) IU/mL. Thirty-four patients achieved clinical cure at the study endpoint with 25.50 weeks of median course of PEG-IFN-α-2b treatment. Twenty-seven patients did not achieve clinical cure at the study endpoint, and the course of treatment was 48 weeks. Clinical cure group had significant lower baseline HBsAg level when compared with non-clinical cure group [78.66(19.54, 204.60) IU/mL vs 2 078.00(442.20, 4 237.00) IU/mL, P<0.001]. At the study endpoint, the white blood cell, platelet, red blood cell, hemoglobin levels were lower than those in baseline (P<0.05), while alanine aminotransferase and asparatate aminotransferase levels were higher than those in baseline (P<0.05). There were no remarkable differences in blood routine tests or liver function between clinical cure and non-clinical cure group at either baseline or study endpoint (P>0.05). Baseline low HBsAg level was a predictor for clinical cure in patients receiving PEG-IFN-α-2b therapy (OR=0.998, 95%CI: 0.998-0.999). No severe adverse events were happened during therapy. Conclusion　PEG-IFN-α-2b-based therapy was well-tolerant, and could achieve high rate of clinical cure in chronic HBV-infected patients who had low baseline HBsAg level.

OBJECTIVE: To explore the improvement effect of electroacupuncture (EA) based on Xingnao Kaiqiao acupuncture (acupuncture for regaining consciousness and opening orifices) on cognitive impairment in mice with Parkinson's disease (PD), and to explore its regulatory mechanisms on the kinesin family member 5A (KIF5A)/mitochondrial Rho GTPase 1 (Miro1) pathway and mitophagy in prefrontal cortical neurons. METHODS: A total of 70 male C57BL/6J mice of clean grade were randomly divided into a normal group (12 mice), a sham operation group (12 mice), and a model pre-screening group (46 mice). Unilateral stereotaxic injection of 6-hydroxydopamine (6-OHDA) into the medial forebrain bundle was adopted to establish the PD model in the model pre-screening group. Twenty-four mice after successful modeling were randomly selected and divided into a model group and an EA group, 12 mice in each one. In the EA group, acupuncture was applied at "Shuigou" (GV26) and bilateral "Sanyinjiao" (SP6) and "Neiguan" (PC6), ipsilateral "Sanyinjiao" (SP6) and "Neiguan" (PC6) were connected to EA respectively, with disperse-dense wave, 5 Hz/20 Hz in frequency, 0.5 mA in current intensity, 20 min a time, 6 times a week for 30 days. Cognitive function was assessed by Y-maze and Morris water maze tests; morphology of prefrontal cortex was observed by H.E. staining; reactive oxygen species (ROS) level in prefrontal cortex was detected by fluorescence probe method; mitochondrial morphology and autophagosome ultrastructure were observed by transmission electron microscopy; the mRNA expression of tyrosine hydroxylase (TH) was detected by quantitative real-time PCR; the protein expression of TH, KIF5A, Miro1, p62, Parkin and PTEN induced kinase 1 (PINK1) was detected by Western blot. RESULTS: Compared with the sham operation group, both the model group and the EA group exhibited increased rotation number of per minute (P<0.001). Compared with the sham operation group, in the model group, the novel arm exploration time of Y-maze test was shortened (P<0.001), the escape latency of Morris water maze test was prolonged (P<0.05) and the platform crossing number of Morris water maze test was reduced (P<0.01); in the prefrontal cortex, the number of cellular vacuole and neurons with karyopyknosis was increased (P<0.001), and mitochondrial autophagosomes could be observed; in the prefrontal cortex, the relative expression of ROS was increased (P<0.001), the protein and mRNA expression of TH was decreased (P<0.001), the protein expression of Miro1, PINK1, Parkin was increased (P<0.001, P<0.01), the protein expression of KIF5A and p62 was decreased (P<0.001). Compared with the model group, in the EA group, the novel arm exploration time of Y-maze test was prolonged (P<0.01), the escape latency of Morris water maze test was shortened (P<0.05) and the platform crossing number of Morris water maze test was increased (P<0.05); in the prefrontal cortex, the number of cellular vacuole and neurons with karyopyknosis was decreased (P<0.001), and the number of mitochondrial autophagosomes reduced and the mitochondrial morphology was improved; in the prefrontal cortex, the relative expression of ROS was decreased (P<0.01), the protein and mRNA expression of TH was increased (P<0.001, P<0.01), the protein expression of Miro1, PINK1, Parkin was decreased (P<0.001, P<0.01, P<0.05), the protein expression of KIF5A and p62 was increased (P<0.01, P<0.05). CONCLUSION Xingnao Kaiqiao electroacupuncture effectively alleviates cognitive impairment and damage of neuronal function in PD mice, its mechanism may be related to the regulation of KIF5A/Miro1 pathway, hence reducing the mitophagy in prefrontal cortical neurons.

BACKGROUND: Research has indicated that the disease burden of alopecia areata (AA) in China exceeds the global average. Therefore, accurate and updated epidemiological information is crucial for policymakers. In this study, we aimed to comprehensively assess the disease burden of AA in China. METHODS: The following four key indicators were utilized: the prevalence of cases; disability-adjusted life-years (DALYs); the age-standardized prevalence rate (ASPR); and the age-standardized DALY rate (ASDR) of AA according to the Global Burden of Disease (GBD) study 2021. We analyzed the epidemiological burden of AA in China during 2021, examined changes between 1990 and 2021, and performed a Bayesian age-period-cohort analysis to predict trends over the course of the next decade (2022-2030). Additionally, a Gaussian process regression model was applied to estimate the relationship between the gross domestic product (GDP) and the ASPR and ASDR of AA at the provincial level between 1992 and 2021. RESULTS: In 2021, the estimated number of patients with AA in China was approximately 3.49 million (95% uncertainty interval [UI], 3.37-3.62 million); of these patients, 1.20 million (95% UI, 1.16-1.25 million) were male and 2.29 million (95% UI, 2.20-2.37 million) were female. This large number of patients with AA resulted in a total of 114,431.25 DALYs (95% UI, 74,780.27-160,318.96 DALYs). Additionally, the ASPR and ASDR were 224.61 per 100,000 population (95% UI, 216.73-232.65 per 100,000 population) and 7.41 per 100,000 population (95% UI, 4.85-10.44 per 100,000 population), respectively; both of these rates were higher than the global averages. The most affected demographic groups were young and female individuals 25-39 years of age. Slight regional disparities were observed, with the northern and central regions of China bearing comparatively higher burdens. Between 1990 and 2021, the health loss and disease burden caused by AA in China remained relatively stable. The ASPR and ASDR of AA increased with the GDP when the annual GDP was less than 2 trillion Chinese yuan; however, a downward trend was observed as the GDP surpassed 2 trillion Chinese yuan. A slight upward trend in the disease burden of AA in China is predicted to occur over the next decade. CONCLUSIONS AA continues to be a public health concern in China that shows no signs of declining. Targeted efforts for young individuals and females are necessary because they experience a disproportionately high burden of AA.
