Objective To investigate the therapeutic effects of modified Lizhong Decoction on gastric and duodenal ulcers(GDU)of the spleen-stomach cold deficiency type,as well as its influence on gastric function and inflammatory mediators.Methods From April 2023 to May 2025,patients diagnosed with gastric dyspepsia of the spleen and stomach cold deficiency type at Nanyang First People's Hospital were randomly assigned to either the Western medicine group(n=53)or the combined therapy group(n=53).The Western medicine group received oral rabeprazole sodium enteric-coated tablets and sucralfate suspension,while the combined therapy group received the same Western medication regimen plus modified Lizhong Decoction.Both groups underwent a 6-week treatment course.Outcomes including clinical efficacy after 6 weeks,gastric mucosal morphology scores,gastric function,levels of inflammatory mediators,mucosal repair-related factors,oxidative stress markers,quality of life before and after treatment,and treatment safety were compared between the two groups.Results The total effective rate in the combined group after 6 weeks of treatment was significantly higher than that in the Western medicine group(P<0.05).After 6 weeks of treatment,both groups showed reduced mucosal thickness,inflammatory cell infiltration,glandular density scores,and decreased serum levels of cholecystokinin(CCK),motilin(MTL),gastrin(GAS),interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),nuclear factor-κB(NF-κB),and malondialdehyde(MDA)compared to baseline,with greater reductions observed in the combined group(P<0.05).Additionally,serum levels of calcitonin gene-related peptide(CGRP),trefoil factor 1(TFF1),epidermal growth factor(EGF),epidermal growth factor receptor(EGFR),and superoxide dismutase(SOD),as well as quality-of-life scores across multiple domains,were significantly increased from baseline in both groups,with the combined group showing superior improvements(P<0.05).During the treatment period,the incidence of adverse reactions was 11.32%in the combined group and 5.66%in the Western medicine group,with no statistically significant difference between the two groups(P>0.05).Conclusion Modified Lizhong Decoction demonstrated a definite therapeutic effect on GDU of the spleen and stomach cold deficiency type,effectively improving gastric mucosal morphology,enhancing gastric function,suppressing inflammatory responses and oxidative stress,promoting the secretion of mucosal repair-related factors,improving patients'quality of life,and exhibiting favorable safety.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

The diagnosis and treatment resources for rare diseases in China are highly imbalanced. The basic diagnosis and treatment capabilities are weak, the diagnosis period for patients is long, and the rates of missed diagnosis and misdiagnosis are relatively high. The establishment of a hierarchical diagnosis and treatment system is the inevitable approach to enhancing the diagnosis and treatment standards of rare diseases. Currently, the implementation of the domestic hierarchical diagnosis and treatment system for rare diseases still confronts numerous challenges, such as ambiguous referral standards and processes of primary medical institutions, and ineffective information interaction among institutions at all levels. Thus, it is essential to facilitate high-level information construction for the hierarchical diagnosis and treatment of rare diseases. This paper explores the process of constructing a multidisciplinary joint remote diagnosis and treatment platform and a health management platform through informatization, with the hope of establishing two closed loops of digital diagnosis and treatment services and health follow-up management for patients with rare diseases, as well as achieving timely diagnosis and lifelong health management for patients. It integrates and optimizes auxiliary diagnostic tools, promotes the rapid dissemination of rare disease diagnosis and treatment experiences to the grassroots, enhances the information construction level of the hierarchical diagnosis and treatment system, and endeavors to address the practical predicament of weak diagnosis and treatment capabilities of rare diseases in grassroots medical institutions. Additionally, this paper proposes an essential approach for multi-dimensional independent innovation to guide the popularization of efficient and high-quality rare disease diagnosis and treatment services. By encompassing innovating the rare disease diagnosis and treatment collaboration network and multidisciplinary diagnosis and treatment model, facilitating the application of the latest biomedical and informatics technologies to the grassroots, and constructing a national intelligent data platform for rare disease innovation, a new model for rare disease services with Chinese characteristics will be established. This will significantly enhance the medical treatment level of rare diseases in China and strive for more benefits for patients.

Purpose To investigate the correlation between lumbar trunk muscle mass at the L3 level and the severity of lumbar facet joint osteoarthritis (FJOA) in the middle-aged and elderly population. Materials and Methods The analysis involved 312 individuals aged between 44 and 82 years in Beijing Jishuitan Hospital from March to June 2016. The total area and CT values of the lumbar trunk muscles at the L3 vertebral body's lower endplate level were measured to calculate the skeletal muscle mass index via OsiriX image processing software. Furthermore,the severity of bilateral lumbar facet osteoarthritis at the L4-5 level was assessed using the Weishaupt grading criteria. CT value of trunk muscle at L3 lower endplate level,trunk muscle area at L3 lower endplate level,skeletal muscle index,body mass index,age and FJOA grade at L4-5 right and left sides were compared between genders. The correlation between the mean value of trunk muscle CT and FJOA grade at the lower endplate level of L3 was analyzed. Results In 109 male patients,the mean trunk muscle was negatively correlated with FJOA grade on the right and left sides of L4-5 (r=-0.25,P=0.002;r=-0.28,P=0.003),while age was positively correlated with FJOA grade on the right and left sides of L4-5 (r=0.23,P=0.034;r=0.21,P=0.033). In 203 female patients,there was a negative correlation between trunk muscle mean and both right and left FJOA grade at L4-5 (r=-0.29,P<0.001;r=-0.33,P<0.001),there was a positive correlation between age and both right and left FJOA grade at L4-5 (r=0.27,P<0.001;r=0.34,P<0.001),and there was a positive correlation between body mass index and both right and left FJOA grade at L4-5 (r=0.20,P=0.018;r=0.23,P=0.004). Partial correlation analysis,controlling for age,showed that the severity of bilateral FJOA at L4-5 was somewhat negatively correlated with the mean value of the L3 trunk muscle in the male and female groups (r=-0.239,-0.249,-0.177,-0.169,all P<0.05). Conclusion Trunk muscle mass at the L3 level is negatively correlated with the severity of FJOA,and FJOA is one of the independent factors of chronic low back pain,strengthening nutritional intake and physical exercise is beneficial to prevent the occurrence and development of sarcopenia,thereby reducing the occurrence and aggravation of FJOA and reducing the burden on patients with chronic low back pain.

The Omicron family of SARS-CoV-2 variants are currently driving the COVID-19 pandemic. Here we analyzed the clinical laboratory test results of 9911 Omicron BA.2.2 sublineages-infected symptomatic patients without earlier infection histories during a SARS-CoV-2 outbreak in Shanghai in spring 2022. Compared to an earlier patient cohort infected by SARS-CoV-2 prototype strains in 2020, BA.2.2 infection led to distinct fluctuations of pathophysiological markers in the peripheral blood. In particular, severe/critical cases of COVID-19 post BA.2.2 infection were associated with less pro-inflammatory macrophage activation and stronger interferon alpha response in the bronchoalveolar microenvironment. Importantly, the abnormal biomarkers were significantly subdued in individuals who had been immunized by 2 or 3 doses of SARS-CoV-2 prototype-inactivated vaccines, supporting the estimation of an overall 96.02% of protection rate against severe/critical disease in the 4854 cases in our BA.2.2 patient cohort with traceable vaccination records. Furthermore, even though age was a critical risk factor of the severity of COVID-19 post BA.2.2 infection, vaccination-elicited protection against severe/critical COVID-19 reached 90.15% in patients aged ≽ 60 years old. Together, our study delineates the pathophysiological features of Omicron BA.2.2 sublineages and demonstrates significant protection conferred by prior prototype-based inactivated vaccines.

Objective:The aim of this study was to explore the associations of muscle size and density with handgrip strength(HGS)and the Timed Up and Go(TUG)test.Methods:Totally 301 participants living in the Xinjiekou community near Beijing Jishuitan Hospital were recruited for CT imaging of the hip and a 1-cm slice of the mid-thigh.The cross-sectional area and density of the gluteus maximus and the mid-thigh muscles were estimated by the Osirix viewer based on CT images.HGS and TUG were also performed in these subjects.Logistic regression analysis was used to evaluate the correlations of muscle density and size with TUG and grip strength.Results:In women, after adjustment for age and BMI, the density of the gluteus maximus was negatively correlated with TUG( P trend=0.0366), while the size of the gluteus maximus and the mid-thigh muscles was not correlated with TUG.In men, the density or size of these muscles was not correlated with TUG.After adjustment for age and BMI, the density of the gluteus maximus was positively correlated with grip strength( P trend=0.0334)and the size of the mid-thigh muscles was also positively correlated with grip strength( P trend=0.0155)in men, but they were not correlated with grip strength in women. Conclusions:There were sex differences in the relationship between muscle size or density and grip strength or timed up and go.The density of the gluteus maximus is associated with muscle strength and physical performance while the size of the mid-thigh muscles is correlated with muscle strength.

Emerging evidence indicates that the gut microbiome contributes to the host immune response to infectious diseases. Here, to explore the role of the gut microbiome in the host immune responses in COVID-19, we conducted shotgun metagenomic sequencing and immune profiling of 14 severe/critical and 24 mild/moderate COVID-19 cases as well as 31 healthy control samples. We found that the diversity of the gut microbiome was reduced in severe/critical COVID-19 cases compared to mild/moderate ones. We identified the abundance of some gut microbes altered post-SARS-CoV-2 infection and related to disease severity, such as Enterococcus faecium, Coprococcus comes, Roseburia intestinalis, Akkermansia muciniphila, Bacteroides cellulosilyticus and Blautia obeum. We further analyzed the correlation between the abundance of gut microbes and host responses, and obtained a correlation map between clinical features of COVID-19 and 16 severity-related gut microbe, including Coprococcus comes that was positively correlated with CD3⁺/CD4⁺/CD8⁺ lymphocyte counts. In addition, an integrative analysis of gut microbiome and the transcriptome of peripheral blood mononuclear cells (PBMCs) showed that genes related to viral transcription and apoptosis were up-regulated in Coprococcus comes low samples. Moreover, a number of metabolic pathways in gut microbes were also found to be differentially enriched in severe/critical or mild/moderate COVID-19 cases, including the superpathways of polyamine biosynthesis II and sulfur oxidation that were suppressed in severe/critical COVID-19. Together, our study highlighted a potential regulatory role of severity related gut microbes in the immune response of host.
