ObjectiveTo observe the effect of Yifei Jianpi prescription on the of signal transducer and activator of transcription protein 1 （STAT1）/interferon regulatory factor 3 （IRF3） signaling pathway in a pneumonia model induced by lipopolysaccharide （LPS） and to explore the mechanism of Yifei Jianpi prescription in improving lung immune and inflammatory responses. MethodsSixty male SPF SD rats were used in this study. Ten rats were randomly assigned to the normal control group， and the remaining 50 were instilled with LPS in the trachea to establish a pneumonia model. After successful modeling， the rats were randomly divided into the model group， dexamethasone group （0.5 mg·kg^-1）， and Yifei Jianpi prescription high-dose （12 mg·kg^-1）， medium-dose （6 mg·kg^-1）， and low-dose （3 mg·kg^-1） groups， with 10 rats in each group. Treatment was administered once daily， and the normal control and model groups received the same volume of normal saline. After 14 days， flow cytometry was used to detect the classification of whole blood lymphocytes. Enzyme-linked immunosorbent assay （ELISA） was used to measure serum levels of immunoglobulin G （IgG）， immunoglobulin A （IgA）， immunoglobulin M （IgM）， and the content of tumor necrosis factor-α （TNF-α）， interleukin-8 （IL-8）， interleukin-6 （IL-6）， and interleukin-10 （IL-10） in alveolar lavage fluid （BALF）. Hematoxylin-eosin （HE） staining was used to observe lung tissue pathology and score the damage. Thymus weight， spleen weight， and wet-to-dry weight ratio （W/D） were recorded. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression of STAT1， IRF3， IL-6， and interferon-alpha （IFN-α） in lung tissues， while Western blot was performed to assess the protein expression of STAT1， IRF3， IL-6， and IFN-α. ResultsCompared with the normal control group， the model group showed significantly increased proportion of B lymphocytes in peripheral blood， decreased proportions of NK cells and CD4⁺/CD8⁺ （P<0.05， P<0.01）， decreased serum levels of IgG and IgA， significantly increased IgM levels （P<0.01）， significantly elevated content of TNF-α， IL-6， and IL-8 in BALF， and significantly decreased IL-10 levels （P<0.01）. Lung tissue damage was evident， with significant increases in thymus and spleen weights and a higher W/D ratio （P<0.01）. The mRNA and protein expression of STAT1， IRF3， IFN-α， and IL-6 in lung tissues was significantly upregulated （P<0.05，P<0.01）. Compared with the model group， the Yifei Jianpi prescription groups showed significantly reduced proportions of B lymphocytes in peripheral blood， increased proportions of NK cells and CD4⁺/CD8⁺ ratios （P<0.05， P<0.01）， significantly increased serum levels of IgG and IgA， significantly decreased IgM levels （P<0.05， P<0.01）， significantly reduced levels of TNF-α， IL-6， and IL-8 in BALF， and significantly increased IL-10 levels （P<0.01）. Lung tissue damage was alleviated， thymus and spleen weights were significantly reduced， and the W/D ratio was markedly decreased （P<0.01）. The mRNA and protein expression of STAT1， IRF3， IFN-α， and IL-6 in lung tissues was significantly downregulated （P<0.05， P<0.01）. ConclusionYifei Jianpi prescription can alleviate lung tissue damage and improve immune and inflammatory responses in LPS-induced pneumonia rats. The mechanism may be related to the inhibition of STAT1/IRF3 signaling pathway activation.

ObjectiveTo investigate the effect and mechanism of cordycepin in inhibiting fat infiltration after rotator cuff injuries in rats by regulating the Wnt/β-catenin signaling pathway， providing a theoretical basis for clinical treatment of rotator cuff injuries. MethodsFifty SPF-grade female SD rats were used in this study， with 10 randomly selected as the blank group. A rotator cuff injury repair model was established by supraspinatus tendon and suprascapular nerve compression. The successfully modeled rats were randomized into model and low-dose （20 mg·kg^-1）， medium-dose （40 mg·kg^-1）， and high-dose （80 mg·kg^-1） cordycepin groups. After 6 weeks of treatment， the gait analysis was performed to assess the limb function in rats. Oil red O staining and Masson staining were employed to observe pathological changes in the muscle tissue. Enzyme-linked immunosorbent assay （ELISA） was used to measure the levels of interleukin-1β （IL-1β）， interleukin-6 （IL-6）， and tumor necrosis factor-α （TNF-α） in the serum. Immunohistochemistry （IHC） was employed to detect the expression of peroxisome proliferator-activated receptor γ （PPARγ） and CCAAT/enhancer-binding protein α （C/EBPα）， which are markers of adipogenesis. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot were employed to determine the mRNA and protein levels， respectively， of Wnt3a， Wnt10b， and β-catenin. ResultsCompared with the blank group， the model group showed decreases in stride length and paw print area （P<0.01）， an increase in ratio of wet muscle mass reduction and a decrease in muscle fiber cross-sectional area （P<0.05）， and decreased ratios of fat infiltration area and collagen fiber area （P<0.01）. Additionally， the model group showed elevated levels of IL-1β， IL-6， and TNF-α （P<0.05）， up-regulated protein levels of PPARγ and C/EBPα （P<0.01）， and down-regulated mRNA and protein levels of Wnt3a， Wnt10b， and β-catenin （P<0.05， P<0.01）. Compared with the model group， the low-， medium-， and high-dose cordycepin groups showed increases in stride length and paw print area （P<0.01）， a decrease in ratio of wet muscle mass reduction and an increase in muscle fiber cross-sectional area （P<0.05）， and increases in ratios of fat infiltration area and collagen fiber area （P<0.05， P<0.01）. In addition， cordycepin lowered the serum levels of IL-1β， IL-6， and TNF-α （P<0.05， P<0.01）， down-regulated the protein levels of PPARγ and C/EBPα （P<0.01）， and up-regulated the mRNA and protein levels of Wnt3a， Wnt10b， and β-catenin （P<0.05， P<0.01）. ConclusionCordycepin can improve the limb function， alleviate rotator cuff muscle atrophy， fat infiltration， and fibrosis， and inhibit inflammation in rats by regulating the Wnt/β-catenin signaling pathway.

ObjectiveTo introduce the three main techniques for tuberculosis screening currently used in China, to systematically evaluate their accuracy in diagnosing latent tuberculosis infection (LTBI), so as to provide scientific basis and recommendations for the formulation of China’s tuberculosis screening strategy. MethodsLiterature on the diagnosis of tuberculosis by tuberculin skin test (TST), interferon-γ release assay (IGRA), and recombinant Mycobacterium tuberculosis fusion protein (EC) skin test from January 1, 2010 to August 22, 2024 was comprehensively retrieved from PubMed, China National Knowledge Infrastructure (CNKI), and Wanfang Database through computerized search. Besides, all the literature was screened in accordance to the inclusion criteria for diagnostic tests, and characteristic information of the literature selected was extracted simultaneously. Meta-analysis was performed using Stata 17.0 software, with a random-effects model used for weighted quantitative synthesis of included literature, calculating pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and their 95% confidence intervals (CI). ResultsA total of 543 relevant articles were retrieved, with 105 ultimately included. Among them, 33 articles reported diagnostic data for TST, with a pooled sensitivity of 0.68 (95%CI: 0.62‒0.73), specificity of 0.67 (95%CI: 0.60‒0.73), positive likelihood ratio of 2.0 (95%CI: 1.7‒2.5), and negative likelihood ratio of 0.48 (95%CI: 0.40‒0.58). Ninety-four articles reported the diagnostic value of IGRAs test, with a pooled sensitivity of 0.88 (95%CI: 0.87‒0.89), specificity of 0.82 (95%CI: 0.79‒0.84), positive likelihood ratio of 4.8 (95%CI: 4.2‒5.6), and negative likelihood ratio of 0.15 (95%CI: 0.13‒0.17). Data on EC skin test was limited, but preliminary analysis showed that it had high sensitivity and specificity. ConclusionIGRA has a significant advantage in diagnosing LTBI, and EC skin test also shows good diagnostic performance, although relevant data is limited. TST remains suitable for large-scale screening due to its cost-effectiveness.

GBA1 gene mutation is an important genetic risk factor for Parkinson’s disease (PD). This paper reports a case of a 43-year-old male PD patient carrying a rare heterozygous Thr408Met mutation in the GBA1 gene identified through whole-exome sequencing, leading to a diagnosis of GBA1-associated PD. The patient’s motor symptoms were primarily characterized by bradykinesia and rigidity, without significant cognitive decline. Treatment with low-dose levodopa combined with a dopamine agonist resulted in significant symptomatic improvement.

To analyze the treatment strategy for a 78-year-old female patient with mismatch repair deficient (dMMR) gastric cancer who achieved long-term survival. After third-line chemotherapy failed, gene testing showed ARID1A p.Gln748fs, c.2733-1G＞T variation, with PD-L1 TPS 30%, CPS 60%. The nivolumab was employed, and two weeks later, the best response was partial response (PR). During the fourth-line immunotherapy maintenance treatment, progression of left adrenal metastasis was observed. The expression of human epidermal growth factor receptor-2 (HER-2) was positive, and the antibody drug conjugate disitamab vedotin (RC48) was chosen for treatment. After 10 months of treatment with nivolumab combined with RC48, the best efficacy was assessed as stable disease (SD), with a progression free survival (PFS) of up to 12 months. Radiotherapy was employed, and immunotherapy was maintained, allowing the patient to achieve a PFS of 18 months again. During immunotherapy, a clinical pharmacist developed a personalized pharmaceutical care plan for this patient. At the last follow-up, this patient achieved 78 months of long-term survival.

Background Non-optimal temperatures pose significant threats to public health. Analyzing the association between temperature exposure and the number of emergency cases of acute alcohol intoxication can provide evidence for optimizing emergency resource allocation and response strategies. Objective To analyze the overall impact and lag effects of non-optimal temperatures on the number of 120 emergency calls for acute alcohol intoxication in Wuxi, and to assess the attributable risk, in order to provide empirical evidence for formulating climate-adaptive public health strategies. Methods Call records of acute alcohol intoxication from Wuxi's 120 emergency service, concurrent air pollutant data, and meteorological data (including daily mean temperature) were collected from January 1, 2014 to December 31, 2020. Distributed lag nonlinear modeling was used for time-series analysis, with cross-basis functions to capture the nonlinear relationship and lag effects between temperature and emergency volume. Confounding factors such as long-term trends, humidity, pollutants [ultimately including ozone (O₃) and fine particulate matter (PM_2.5)], day of the week, and holidays were controlled. The maximum lag period was set to 14 days. Single-day lag and cumulative lag effects of extreme temperatures were analyzed, followed by sensitivity analysis. Effects were quantified using relative risk (RR) and 95% confidence intervals (95%CI), and attributable fractions and numbers for different temperature ranges were calculated. Results A total of 10705 emergency cases of acute alcohol intoxication were included during the study period, with males accounting for 89.5% and individuals aged 18–50 years accounting for 83.4%. A non-linear "U-shaped" association was observed between daily mean temperature and the number of emergency calls, with an optimal temperature of 13.3 ℃. The effect of the extreme low temperature (1.88 ℃) was statistically significant from lag1 to lag3 after exposure (P<0.05), with the maximum effect at lag1 (RR=1.063, 95%CI: 1.002, 1.129). The extreme high temperature (32.3 ℃) showed an immediate effect, with maximum effect at lag0 (RR=1.374, 95%CI: 1.248, 1.512). The cumulative effect analysis showed that the risk associated with high temperature was the highest at lag0–3 (RR=2.000, 95%CI: 1.667, 2.399), while the risk associated with low temperature was the highest at lag0–14 (RR=1.462, 95%CI: 1.042, 2.051). The attribution analysis indicated that the mild heat (>24.7–30.8 ℃) and heat (>30.8–33.5 ℃) contributed the largest numbers of attributable cases, with 591 cases (95%CI: 56, 1032) and 190 cases (95%CI: 51, 309), respectively. The corresponding attributable fractions were 5.81% (95%CI: 0.80%, 9.94%) and 1.87% (95%CI: 0.49%, 2.96%), respectively. Conclusion Both extreme high and low temperatures significantly increase the number of 120 emergency calls for acute alcohol intoxication in Wuxi. High temperature exhibit an acute effect, while low temperature show a delayed effect. Mild heat have a significant impact on the emergency burden. It is recommended that emergency departments optimize resource allocation according to climatic characteristics and strengthen emergency responses during extreme weather to reduce alcohol-related health burden.

The biliary microbiota is an important component of the biliary system, the structure changes and dysbiosis of the biliary microbiota are closely related to the occurrence and development of biliary diseases. Recent studies have found that the dysbiosis of the biliary microbiota can lead to the occurrence of various biliary diseases such as cholelithiasis, cholangitis, and biliary tract cancer. However, the specific mechanisms of some of these diseases remain unclear. In addition, the alternation of biliary microbiota may also lead to the occurrence of postoperative complications of biliary diseases, such as the risk of infection increased after laparoscopic cholecystectomy (LC) and endoscopic retrograde cholangiopancreatography (ERCP). Although some studies have begun to explore the connection between biliary microbiota and biliary diseases, most research have mainly focused on a single disease type or specific microorganisms. There has been no comprehensive and systematic review of the overall changes in biliary microbiota across different diseases and their association with post biliary surgery infection.Therefore, this article presents a systematic review of current advances linking the alternations of biliary microbiota to the development of biliary diseases and their postoperative infections, as well as the changes in the biliary microbiota before and after various biliary diseases and their surgeries, aiming to provide insightful methods for the early diagnosis, prevention and treatment of biliary diseases and management of postoperative infections.

Objective To investigate the relationship between sperm DNA fragmentation index(DFI),high reactive oxygen species(ROS)rate,high mitochondrial membrane potential(MMP)rate,and progressive motility(PR)in patients with idiopathic astheno-zoospermia.Methods A total of 250 patients who visited the Male Department of Reproductive Medicine Center,Tangdu Hospital,from December 2022 to November 2023 were enrolled in this study.The patients were divided into mild(20％≤PR＜32％,n=86),moderate(10％≤PR＜20％,n=67),and severe(PR＜10％,n=47)asthenozoospermia groups,and a normal group(female factor infertility,normal semen parameters,PR≥32％,n=50)was formed based on their PR values.The levels of sperm DFI,high ROS and MMP rates were measured using flow cytometry,and their correlations with PR were analyzed.Results Compared with the normal group,the asthenozoospermia groups showed significantly lower sperm concentration,motility,normal morphology percentage and high MMP rate(P＜0.05),but significantly high DFI and ROS rate(P＜0.01).The severe asthenozoospermia group had significantly high DFI and ROS rate and high MMP rate was lower than that in the mild and moderate groups(P＜0.0I).No significant differences in DFI,high ROS rate and MMP rates were found between the mild and moderate groups(P＞0.05).As the severity of asthenozoospermia increased,DFI and high ROS rate showed an increasing trend,while high MMP rate decreased.Correlation analysis revealed a signifi-cant positive correlation between PR and high MMP rate(r=0.439,P＜0.01)and significant negative correlations between PR and high ROS rate(r=-0.435,P＜0.01),DFI(r=-0.478,P＜0.01).Conclusion The patients with idiopathic asthenozoospermia ex-hibit altered levels of sperm DFI,high ROS and MMP rates,which are associated with the severity of asthenozoospermia.Elevated ROS levels may lead to sperm DNA damage and mitochondrial dysfunction,resulting in decreased sperm progressive motility.

In traditional clinical teaching of impacted tooth extraction, there are problems including limited observation fields for students, insufficient doctor-patient communication training, inadequate clinical thinking development, and low levels of clinical participation. Based on the core elements of visualizing jaw structure with perspective, formulating clinical strategy, immersing in clinical participation, and cultivating the spirit of caregiving, we developed a virtual reality simulation teaching platform for the clinical decision analysis of impacted tooth extraction. The virtual simulation-based platform can create three different impacted tooth scenarios in 3D, which demonstrates the process of clinical decision analysis of impacted tooth extraction through virtuality-reality interaction, allowing students to immerse in the discovery, analysis, and resolution of the medical and humanistic problems in the process of impacted tooth extraction. The questionnaire survey showed that 81.36% (48/59) of the students believed that the software could improve their clinical thinking ability; 76.27% (45/59) of the students believed that it could help them master the basic process of impacted tooth extraction; and 62.71% (37/59) of the students believed that it could improve their skills of impacted tooth extraction. By providing immersive learning experience, constructive teaching design, and multi-dimensional teaching evaluation, the software achieved the goals of cultivating students' clinical thinking ability and professional literacy in oral and maxillofacial surgery.

Objective:To investigate the clinical application effect of enhanced recovery after surgery(ERAS) in the perioperative period of primary repair for children with hypospadias.Methods:Non-randomized controlled study.Retrospective analysis was made on clinical data of 206 children with hypospadias admitted to the Department of Urology, Shanxi Children′s Hospital from March 2018 to March 2022.According to whether the concept of ERAS was adopted for perioperative management of children, they were divided into the ERAS group(109 cases) and the non-ERAS group(97 cases). t-test and Chi-square test were used to analyze the differences between the two groups of patients in hospitalization days, hospitalization costs, pain scores on the first day after surgery, average number of bowel movements within 5 days after surgery, first out-of-bed activity time, hospital satisfaction score, and complication rate. Results:Pediatric patients in the ERAS group showed better outcomes compared to the non-ERAS group: shorter hospital stays[(7.71±1.12) d vs.(21.00±1.07) d], lower hospitalization costs[(10 043.21±1 341.00) yuan vs.(12 993.44±1 081.00) yuan], lower postoperative pain scores on the first day[(5.21±1.32) points vs.(6.09±1.07) points], more frequent bowel movements within 5 days[(5.16±0.65) times vs.(2.91±0.48) times], earlier time to first out-of-bed activity[(5.03±0.61) d vs.(7.12±0.57) d], and higher hospital satisfaction scores[(4.71±0.21) points vs.(4.14±0.15) points], and the differences were statistically significant(all P<0.05).Additionally, the ERAS group had lower rates of fever(6.42%, 7/109) and constipation(3.67%, 4/109) before urinary catheter removal compared to the non-ERAS group[21.64%(21/97) and 28.87%(28/97), respectively](all P<0.05).There were no significant differences in the incidences of complications such as urethral prolapse, infection, delayed wound healing, and bleeding, as well as urethral stricture, urethral fistula, and urethral diverticulum after urinary catheter removal between the two groups(all P>0.05). Conclusions:ERAS protocol applied in the perioperative period of primary repair for children with hypospadias can shorten the hospitalization time, lower the hospitalization costs, and accelerate the rehabilitation of children.It is worth further promotion.
