ObjectiveTo evaluate the clinical efficacy and economic value of the Jiangsu Traditional Chinese Medicine (TCM) Diagnosis and Treatment Protocol for Dominant Diseases (abbreviated as the Diagnosis and Treatment Protocol) in adult patients with non-severe community-acquired pneumonia (CAP) based on real-world clinical data. MethodsA retrospective real-world cohort study was conducted using electronic medical records of adult patients hospitalized for non-severe CAP from September 1st, 2023 to December 31st, 2024 across 10 TCM hospitals in Jiangsu province. Patients were classified into an exposure group and a non-exposure group based on whether they received Chinese herbal medicine (CHM) according to the Diagnosis and Treatment Protocol. The non-exposure group received only conventional western medicine, while the exposure group additionally received differentiated CHM for at least five consecutive days. Outcomes were compared between two patient groups, including cough resolution rate, sputum resolution rate (assessed by volume, color, and consistency), incidence of abnormal C-reactive protein (CRP), incidence of abnormal white blood cell (WBC) count, and radiographic resolution rate of pulmonary infiltrates on chest imaging. Multivariable logistic regression was performed to identify factors influencing clinical efficacy. Subgroup analyses were conducted according to age, gender, smoking status, history of hypertension, and pneumonia severity score (CURB-65), and the efficacy of treatment for cough and sputum was analyzed within each subgroup. Cost-effectiveness analysis was conducted using cough resolution rate as the outcome measure, evaluating the pharmacoeconomics of the two groups. ResultsA total of 1688 patients were included with 1293 in the exposure group and 395 in the non-exposure group. Compared to the non-exposure group, the exposure group demonstrated significantly higher resolution rates of cough, sputum volume, color, and consistency, as well as a significantly lower incidence of abnormal CRP (P<0.05). No statistically significant difference was observed between the groups in terms of abnormal WBC count and radiographic resolution rate of pulmonary infiltrates (P>0.05). Logistic regression analysis showed that the cough resolution rate in the exposure group was 1.83 times that of the non-exposure group, while the probabilities of resolution in sputum volume, color, and consistency were 1.37, 2.09, and 1.56 times those of the non-exposure group, respectively (P<0.05). Subgroup analyses showed that the exposure group achieved significantly higher cough resolution rates across most subgroups except for populations with a CURB-65 score ≥2 or those with a history of hypertension (P<0.05). Specifically, among females, patients aged ≥18 and <65 years, non-smokers, those without hypertension, and those with a CURB-65 score of 0, the exposure group showed a higher cough resolution rate than the non-exposure group (P<0.05). From an economic perspective, total hospitalization cost, length of stay, antibiotic cost, and CHM cost all differed significantly between groups (P<0.05). The cost-effectiveness ratio (CER) was 10,788.80 CNY/case in the exposure group, while 22,513.80 CNY/case in the non-exposure group. This implies that, compared with the exposure group, the non-exposure group incurred an additional 17,302.27 CNY to achieve one case of cough resolution. When the willingness-to-pay threshold ranged from 0 to 50,000 CNY, the probability of economic advantage was consistently higher in the exposure group than in the non-exposure group. ConclusionOn the basis of conventional western medicine, the addition of CHM in accordance with the Diagnosis and Treatment Protocol can effectively improve clinical symptoms, reduce inflammatory markers, promote clinical recovery, and is more cost-effective in treating adults with non-severe CAP.

ObjectiveTo observe the real‑world effectiveness and economic outcomes of Weishi Qingjin Formula (苇石清金方, WQF) in the treatment of adult community‑acquired pneumonia (CAP) with phlegm‑heat obstructing the lung syndrome. MethodsBased on a multicenter, real-world retrospective cohort study, clinical data were collected from hospitalized adult patients diagnosed with non‑severe CAP and phlegm‑heat obstructing the lung syndrome in 10 traditional Chinese medicine (TCM) hospitals in Jiangsu province. Patients were divided into an exposure group (those who received oral WQF) and a non‑exposure group (those who did not). The following outcomes were compared between the two groups before and after treatment, which were remission rates of clinical symptoms including cough, expectoration (sputum volume, color, consistency), and chest pain, levels of inflammatory markers including C‑reactive protein (CRP) and white blood cell count (WBC), and the rate of pulmonary inflammatory absorption on chest CT. Subgroup analyses were performed based on age, gender, smoking status, presence of hypertension, and the severity of community-acquired pneumonia (CURB‑65) score, comparing the two groups in terms of cough remission rate, chest pain remission rate, and chest CT absorption rate. For health economic evaluation, cost‑effectiveness analysis was used to calculate the cost‑effectiveness ratio (CER) and incremental cost‑effectiveness ratio (ICER). Univariate sensitivity analysis and probabilistic sensitivity analysis were performed to test the robustness of the results. ResultsA total of 647 patients in the exposure group and 1491 patients in the non-exposure group were included in the final statistical analysis. There was no statistically significant difference in length of hospital stay, gender, marital status, smoking history, bronchoscopy history, and comorbidities between the groups (P>0.05), but age, CURB-65 score, and antibiotic use. The exposure group had significantly higher remission rates of cough and sputum consistency than the non-exposure group (P<0.05). After adjusting for confounders using propensity score matching and logistic regression, the cough remission rate in the exposure group was 1.49 times that of the non-exposure group (P<0.01). No significant difference was observed between groups in the reduction rates of CRP and WBC, and in the rate of pulmonary inflammatory absorption on chest CT (P>0.05). Subgroup analyses revealed that the cough remission rate in the exposure group was significantly better than that in the non-exposure group except for patients aged ≥65 years, smokers, hypertensive patients, those using other type antibiotics or not using antibiotics, and those with a CURB-65 score ≥1 (P<0.05). Among smokers, the chest pain remission rate in the exposure group was 4.38 times that of the non-exposure group (P<0.01). No significant difference in chest CT absorption rate was found between groups across subgroups of gender, age, hypertension status, or antibiotic type (P>0.05). In terms of economic evaluation, CER was 10,877.60 CNY/case in the exposure group and 16,773.10 CNY/case in the non-exposure group. Compared to the exposure group, the non-exposure group incurred an additional 15,034.26 CNY to achieve one case of cough resolution, indicating a more favorable cost-effectiveness profile. Probabilistic sensitivity analysis yielded results consistent with the cost-effectiveness analysis, confirming the robustness of the findings. ConclusionWQF demonstrates significant efficacy in improving cough symptoms in the treatment of adult CAP with phlegm-heat obstructing the lung syndrome, and also exhibits favorable economic benefits.

OBJECTIVE To investigate the mechanism of Huangqin decoction in improving ulcerative colitis (UC) through the gut microbiota-tryptophan metabolism-aryl hydrocarbon receptor (AhR) axis. METHODS Mice were randomly divided into normal group (normal saline), model group (normal saline), microbiota depletion-model group (normal saline), microbiota depletion-Huangqin decoction group (9.1 g/kg, by crude drug, similarly hereinafter), Huangqin decoction group and mesalazine group (positive control group, 0.4 g/kg), with 6 mice in each group. Microbiota depletion was achieved by providing free access to a mixed antibiotics for 10 days. The UC model was induced by administering 2.5% dextran sulfate sodium solution for 7 days. After successful modeling, each treatment group received corresponding drugs or normal saline intragastrically once daily for 10 days. After the final administration, body weight change ratio, disease activity index (DAI) score, and colon length were evaluated; colon pathological changes were observed; serum levels of interleukin-6 (IL-6), IL-10, IL-22, and tumor necrosis factor-α (TNF-α) were measured; the expressions of Occludin, zonula occluden-1 (ZO-1), and AhR in colon tissue were detected; fecal samples were subjected to high-throughput sequencing to analyze targeted tryptophan metabolomics. RESULTS Compared with the model group, Huangqin decoction group showed reduced infiltration of inflammatory cells in the colon tissue and restoration of the intestinal mucosal structure. Body weight change ratio, colon length, serum content of IL-10, the expressions of Occludin, ZO-1 and AhR in colon tissue and the contents of tryptophan metabolites indole-3-propionic acid (IPA), N -acetylserotonin (NAS) and indole-3-acetic acid (IAA) were all significantly increased ( P <0.05); DAI score, serum levels of IL-6, TNF-α, and IL-22 and the content of tryptophan metabolite indole-3-ethanol were significantly decreased ( P <0.05); gut microbiota structure was improved, with increased relative abundances of beneficial bacteria such as Lactobacillus , and decreased relative abundances of pathogenic bacteria such as Escherichia-Shigella . However, after antibiotic-induced microbiota depletion, although Huangqin decoction significantly increased the content of NAS in the feces of mice, the expression of AhR protein in colon tissue did not increase concurrently. CONCLUSIONS Huangqin decoction can repair the intestinal mucosal barrier in UC mice by regulating the gut microbiota and promoting the production of IPA and IAA, thereby activating AhR. This suggests that an intact gut microbiota is an important prerequisite for Huangqin decoction to exert its AhR-regulating effects.

Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) block downstream signaling pathways by inhibiting receptor tyrosine kinase activity, consequently suppressing proliferation, invasion and metastasis of tumor cells. EGFR-TKIs have been proven to be highly effective in patients with late non-small cell lung cancer (NSCLC) harboring EGFR sensitive mutations, significantly better than chemotherapy. Third-generation EGFR-TKIs, such as osimertinib, have emerged as the first-line treatment for advanced NSCLC patients with sensitive EGFR mutations. However, there are still some patients who exhibit primary resistance upon initial treatment with EGFR-TKIs. The exact mechanism of primary resistance remains unknown, and may be related to factors such as the structure of EGFR mutation subtypes, concurrent mutations, BIM deletion polymorphism, and high expression of programmed cell death-ligand 1. This review summarizes the molecular mechanisms of primary resistance to EGFR-TKIs and discusses potential therapeutic strategies, with the goal of optimizing precision targeted therapy for NSCLC patients.

To systematically analyzed the reporting status of core elements in publicly available clinical practice guideline(hereafter referred to as "guideline") protocols published domestically and internationally over the past decade, identified existing problems, and provided evidence to inform the standardized writing and publication of future guideline protocols. A systematic search was conducted in Chinese and English databases for clinical practice guideline protocols published during the past ten years. The basic characteristics and reporting of core elements—including registration information, conflict of interest management, evidence grading, development process and timeline planning, as well as dissemination and implementation—were extracted and analyzed. Chi-square tests were performed to explore associations between protocol characteristics and the reporting of core elements. A total of 94 guideline protocols were included, of which 67 were in Chinese(71.28%) and 27 were in English(28.72%). Overall, 82.98% of the guideline protocols were registered, 92.55% reported management of conflicts of interest, 97.87% reported evidence searching, 88.30% reported evidence grading, and 89.36% described dissemination and implementation strategies. However, only 55.32% reported the guideline development process, and merely 23.40% reported timeline planning. Further analysis indicated that the reporting of registration, evidence searching, development process, and timeline planning was associated with year of publication. Differences were observed between domestic and international guidelines in reporting registration, conflict of interest management, development process, time planning, and dissemination and implementation. Guidelines intended for development exhibited higher reporting rates for registration, development process, and dissemination and implementation compared to those planned for updating or adaptation. Although current guideline protocols demonstrate relatively adequate reporting of methodological elements, deficiencies remain in development process and timeline planning. Future efforts should focus on promoting the publication and standardized reporting of guideline protocols, enhancing the international recognition of registration platforms, and strengthening the development process and timeline planning to advance the scientific rigor and transparency of guideline development.

OBJECTIVE To evaluate the anticoagulant efficacy and safety of nafamostat mesylate (NM) in the treatment of uremic patients at high risk of bleeding undergoing continuous veno-venous hemofiltration (CVVH) with different methods (pre- dilution and post-dilution). METHODS A total of 130 uremic patients at high risk of bleeding who underwent CVVH treatment in the nephrology department of Chongqing University Three Gorges Hospital from July 2023 to September 2024 were selected. They were divided into pre-dilution group and post-dilution group according to the random number table method, with 65 cases in each group. Both groups of patients received CVVH treatment under NM anticoagulation. The pre-dilution group adopted the pre-dilution replacement method, while the post-dilution group adopted the post-dilution replacement method. The coagulation, pressure, and usage duration of the filter and dialysis circuit venous reservoirs were compared between the two groups. The changes in prothrombin time (PT), prothrombin time-international normalized ratio (PT-INR), activated partial thromboplastin time (APTT), and fibrinogen (FIB) in the peripheral venous blood before the heparin pump and after the filter at 1, 4 and 7 h of CVVH treatment, as well as 20 min after the end of treatment, were compared between the two groups. The single-compartment urea clearance rate (spKt/V), β2-microglobulin (β2-MG) clearance rate and the incidence of adverse reactions were duni2007@foxmail.com compared between the two groups. RESULTS Both the pre-dilution and post-dilution groups had 60 patients who completed the study. The incidence of grade Ⅱ-Ⅲ coagulation of the filter and venous reservoirs, as well as the number of patients with transmembrane and venous pressure alarm intervention in the post- dilution group were significantly higher or more than those in the pre-dilution group (P<0.05), while usage time of the filter and the pipeline in the post-dilution group was significantly shorter than that in the pre-dilution group (P<0.05). The APTT values before the heparin pump as well as PT and APTT values after the filter at 1 h, 4 h, and 7 h of CVVH treatment in the post-dilution group were significantly higher than those in the pre-dilution group (P<0.001). There were no significant differences in PT, PT- INR, APTT and FIB between the two groups of patients 20 min after the end of treatment (P>0.05). The spKt/v and β2-MG clearance rates in the post-dilution group were significantly higher than those in the pre-dilution group (P<0.001). There was no significant difference in the incidence of adverse reactions between the two groups (P>0.05). CONCLUSIONS When NM is used as an anticoagulant in the CVVH treatment of uremic patients at high risk of bleeding, compared with the pre-dilution treatment method, the post-dilution treatment method has a higher incidence of filter and dialysis tubing venous reservoir, a shorter usage time of the filter and pipeline, and a greater impact on extracorporeal coagulation, but has a higher solute clearance rate. Clinically, different dilution methods can be selected according to the different treatment needs of patients.

Objective To analyze the epidemiological and spatial clustering characteristics of varicella in Changzhou from 2018 to 2024, and to provide a theoretical support for the formulation of prevention and control measures. Methods The reported case information of varicella in Changzhou from 2018 to 2024 was collected through the China Information System for Disease Control and Prevention, and the three-dimensional distribution characteristics were analyzed. The incidence trend was analyzed by Joinpoint regression, and the spatial autocorrelation analysis was performed by Arc GIS 10.5 software. The spatiotemporal scanning analysis was carried out with SaTScan 10.1.2 software. Results From 2018 to 2024, a total of 42,132 cases of varicella were reported in Changzhou, with an average annual incidence of 116.25/100,000. The reported incidence showed a downward trend, with an annual percentage change (APC) of -21.96% (95%C1: -32.63%~-9.33%, P<0.01). The incidence showed a “bimodal distribution”, and the age group was mainly under 15 years old (29,086 cases, accounting for 69.04%). The difference in incidence between men and women was statistically significant (χ2= 92.83, P<0.001), and the incidence gradually decreased with age ( χ2trend=112771.44, P<0.001). Global autocorrelation analysis showed that there was spatial aggregation in the six years (P<0.05), and local autocorrelation analysis showed that most of the towns (streets) in the three central urban areas of Tianning District, Zhonglou District, and Xinbei District, as well as some towns (streets) in Liyang City, Wujin District, and Economic Development Zone were high-high aggregation areas. Spatiotemporal scanning analysis showed that the first type of aggregation area was most of the towns (streets) in Tianning District, Zhonglou District and Xinbei District (23, accounting for 92%), and some towns (streets) in Wujin District and Economic Development Zone (RR=3.76, P<0.001), and the second type of aggregation area was most of the towns (streets) in Liyang City (7, accounting for 70%) (RR=3.66, P<0.001). Conclusion The reported incidence of varicella in Changzhou City shows a downward trend, with multiple spatial and temporal clusters. The prevention and control of varicella in high-risk clustering areas, peak hours and high-risk populations should be strengthened, and intervention measures should be taken as soon as possible.

ObjectiveTo observe the effects of Yangjing Zhongyutang (YJZYT) on mitochondrial biogenesis and oxidative stress damage mediated by the silent information regulator 1 (SIRT1)/peroxisome proliferator-activated receptor gamma coactivator-1alpha (PGC-1α) signaling pathway in cyclophosphamide (CTX)-induced rats with diminished ovarian reserve (DOR), and to explore its mechanism in improving ovarian reserve function and follicular development. MethodsForty-two 8-week-old female SD rats with normal estrous cycles were randomly divided into a blank control group (n=7) and a model group (n=35). Rats in the model group received a single intraperitoneal injection of CTX (90 mg·kg-1) to establish the DOR model. After modeling, estrous cycles were monitored for 7 consecutive days, and model success was confirmed based on criteria for estrous cycle disruption. After successful modeling, rats were divided into groups for intervention: estradiol valerate group (0.09 mg·kg-1), and YJZYT high-, medium-, and low-dose groups (19.98, 9.99, 5.00 g·kg-1). The blank control group and model group were given an equal volume of distilled water by gavage. All groups received daily gavage once for 4 consecutive weeks. The general state, body weight, and ovarian wet weight of rats were observed and recorded, and the ovarian organ index was calculated. Enzyme-linked immunosorbent assay (ELISA) was used to measure serum levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), anti-Müllerian hormone (AMH), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px). Hematoxylin-eosin (HE) staining was performed to observe ovarian histomorphological changes and follicular development status. Immunofluorescence was used to detect reactive oxygen species (ROS) expression levels. Colorimetric assays were employed to measure adenosine triphosphate (ATP) and malondialdehyde (MDA) content in ovarian tissues. Quantitative Real-time polymerase chain reaction (Real-time PCR) was used to detect mitochondrial DNA (mtDNA) copy number and the mRNA expression levels of key genes including SIRT1, PGC-1α, nuclear respiratory factor 1 (NRF1), and mitochondrial transcription factor A (TFAM). Western blot was performed to detect the protein expression levels of SIRT1, PGC-1α, NRF1, and TFAM. ResultsCompared with the blank group, rats in the model group exhibited disrupted estrous cycles, obviously reduced body weight, and decreased ovarian index (P<0.05). Ovarian histopathology revealed cortical thinning, loose structure, and a significant reduction in both primordial and growing follicles (P<0.01). Serum FSH and LH levels were significantly elevated (P<0.01), while E2 and AMH levels were obviously reduced (P<0.05, P<0.01). ATP content and mtDNA copy number decreased in ovarian tissue (P<0.01), ROS expression increased, MDA levels rose, while SOD and GSH-Px activities obviously decreased (P<0.05, P<0.01), mRNA and protein expression levels of SIRT1, PGC-1α, NRF1, and TFAM were obviously downregulated (P<0.05, P<0.01). After treatment, compared with the model group, body weight and ovarian index obviously recovered in rats administered various doses of YJZYT (P<0.05), serum E2 and AMH levels increased, while FSH and LH levels obviously decreased (P<0.05, P<0.01), ovarian tissue ATP content and mtDNA copy number were up-regulated, ROS and MDA levels decreased, and antioxidant enzymes SOD and GSH-Px activity obviously increased (P<0.05, P<0.01), Gene and protein expression levels related to the SIRT1/PGC-1α /NRF1/TFAM signaling pathway were obviously up-regulated compared to the model group (P<0.05, P<0.01), HE staining revealed that ovarian structure gradually recovered to integrity in all treatment groups, with a obviously increase in the number of primordial and growing follicles (P<0.05, P<0.01). Granulosa cells were neatly arranged, indicating marked improvement in ovarian function. ConclusionYJZYT may improve ovarian function and follicular development in rats with diminished ovarian reserve by activating the SIRT1/PGC-1α signaling pathway, promoting mitochondrial biogenesis, enhancing mitochondrial function, and alleviating oxidative stress damage.
