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.

ObjectiveTo conduct an epidemiological investigation and analysis of a clustered scabies outbreak in a middle school, so as to provide evidence for developing targeted prevention and control strategies. MethodsCase data on a clustered scabies outbreak occurring in a middle school of Shaanxi Province in 2025 were collected. Field epidemiological approaches were adopted to define cases, search for infected individuals, and describe the temporal, spatial, and population distribution. Specimens were collected from individuals and surrounding environments for laboratory testing. ResultsA total of 25 scabies cases were identified in 4 classes and 9 dormitories of the school. All cases were first-year high school students. The overall attack rate was 6.00% (25/414); the attack rate was 10.53% (22/209) among male students and 1.46% (3/205) among female students. The disease course ranged from 10 to 30 days, with a median duration of 14 days, and 3 students (12.00%) continued attending classes with ongoing infection. Skin scrapings collected from lesion sites of 3 patients were examined under microscopy, all of which were positive for Sarcoptes scabiei; no laboratory testing was performed for the remaining cases. This clustered scabies infection outbreak lasted for one month. All affected students recovered completely without severe complications or deaths, and the outbreak was effectively contained. ConclusionThis scabies infection is a clustered school-based scabies outbreak caused by Sarcoptes scabiei. Affected patients present relatively severe symptoms and a prolonged disease course. Scientific and standardized preventive systems should be established to enable timely early warning and emergency response.

Objective To investigate the protective effect of benzoylaconine(BAC)on H9c2 cardio-myocytes after oxygen glucose deprivation/reoxyenation(OGD/R)injury.Methods After an in vitro model of OGD/R injury was established in H9c2 cells,the cells were treated with BAC at different concentrations(0,25,50,75,100 μmol/L)to determine its optimal dose.Then,H9c2 cells were randomly divided into control group,OGD/R group,OGD/R+BAC group(75 μmol),OGD/R+LY294002 group(PI3K/Akt inhibitor),and OGD/R+LY294002+BAC group.Corre-sponding reagent kits were used to determine cell viability and LDH level,as well as the expres-sion levels of TNF-α,IL-6,IL-1β,MDA and GSH-Px in the cells.Western blotting was applied to detect the expression of the PI3K/Akt pathway proteins,as well as autophagic proteins such as LC3,Beclin1,and P62.Results Compared to the control group,the cell viability was significantly decreased,and LDH level was obviously increased in the OGD/R group(P＜0.01).Treatment of 75 μmol/L BAC significantly increased the cell viability(0.87±0.06 vs 40.49±0.06,P＜0.01)and decreased the LDH level(86.75±7.79 U/L vs 234.42±6.20 U/L,P＜0.01)when compared to the levels of the OGD/R group.OGD/R injury induced notable increases in TNF-α,IL-6,IL-1β,and MDA expression levels,while decrease of GSH-Px expression level(P＜0.01),and down-regulation of p-PI3K,p-Akt and P62 and up-regulation of LC3 Ⅱ/LC3 Ⅰ and Beclin-1(P＜0.01)when compared with the control group.Treatment of 75 μmol/L BAC increased the levels of p-PI3K,p-Akt,and P62 proteins(0.90±0.07 vs 0.58±0.04,1.02±0.02 vs 0.49±0.01,1.48±0.05 vs 0.87±0.04)and decreased those of LC3 Ⅱ/LC3 Ⅰ and Beclin-1(0.52±0.01 vs 1.24±0.04,0.12±0.01 vs 0.32±0.02)when compared with the OGD/R group(P＜0.01).Conclusions BAC attenu-ates the inflammatory response and oxidative stress of myocardial cells after OGD/R injury,regu-lates autophagy homeostasis,and reduces myocardial cell damage.Its regulatory effect on myocar-dial autophagy homeostasis may be related to the activation of the PI3K/Akt pathway.

Aim To investigate the effects of rutae-carpine(RUT)on lung inflammation in septic mice and the underlying mechanisms.Methods The sepsis mouse model was generated by intraperitoneal injection of lipopolysaccharide(LPS)at 5 mg·kg-1.The mice were randomly divided into the Control group,Model group,Low-dose,Medium-dose,High-dose RUT(5,10,20 mg·kg-1)treatment group and dexamethasone(DEX,2 mg·kg-1),with 10 mice in each group.The mice were intraperitoneally injected with RUT 30 min before LPS injection.HE staining was used to observe the morphology of lung tissues,and activity of my-eloperoxidase was determined to assess the neutrophil infiltration.Wet/dry weight ratio and Evan's blue ex-travasation of lung tissues were examined to assess lung edema.Survival analysis was performed to determine the in vivo protective effects of RUT.ELISA and quan-titative RT-PCR analysis were employed to determine the contents and gene expression of pro-inflammatory mediators,including tumor necrosis factor-α(TNF-α),interleukin-1 β(IL-1 β),IL-6,and IL-18 in lung tis-sues.Western blot was used to detect the protein levels of p38 MAPK,NF-κB,Caspase-1,NOD-like receptor family pyrin domain containing 3(NLRP3)and IL-18.Results RUT at 10-20 mg·kg-1 could dose-de-pendently inhibit leukocyte infiltration,reduce pro-in-flammatory mediator production,vascular permeability and wet/dry weight ratio in lungs,similar to the effects induced by DEX.The mice treated with RUT exhibited increased survival,down-regulated expressions of p-p38 MAPK,p-NF-κB,Caspase-1,NLRP3,and IL-18 pro-teins in lungs,with decreased IL-18 mRNA level.Conclusions RUT exhibits protective effects on sep-sis-induced lung injury,manifested by reduced inflam-mation and edema,potentially via inhibition of p38 MAPK signaling pathway and inflammasome formation.

Objective:To investigate the changes in accommodative facility after implantation of V4c implantable collamer lens (ICL) using the intelligent flipper (iFLIP).Methods:A serial case-control study was conducted.Forty patients (80 eyes) who underwent ICL implantation of V4c for myopia correction and completed the follow-up were enrolled at the Affiliated Hospital of Guizhou Medical University from April 2022 to April 2023.Monocular and binocular accommodative facility, adjustment time, and relaxation time were measured with iFLIP before operation and at 1 week, 1 month, 3 months, and 6 months after operation.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of the Affiliated Hospital of Guizhou Medical University (No.2023-983).Written informed consent was obtained from each subject.Results:Monocular and binocular uncorrected visual acuity at 1 week, 1 month, 3 months and 6 months after surgery were significantly improved compared with before surgery, and the differences were statistically significant (all P<0.05).Monocular and binocular postoperative accommodative facility gradually increased over time, and the increase gradually decreased and gradually stabilized.Before operation and 1 week, 1 month, 3 months, and 6 months after operation, the monocular accommodative facility was (7.99±3.42), (10.19±4.25), (12.03±4.24), (13.10±4.66) and (13.64±4.40)cpm, and the binocular accommodative facility was (9.01±3.63), (9.56±3.38), (11.58±4.00), (13.31±3.64), and (14.03±3.72)cpm, respectively, with statistically significant overall differences ( F=24.02, 14.46; both P<0.001).Monocular accommodative facility was higher than before surgery at each time point after surgery, and was higher than 1 week after surgery at 1, 3, and 6 months after surgery, with statistically significant differences (all P<0.05).Binocular accommodative facility was higher at 1, 3, and 6 months after surgery than that before surgery and 1 week after surgery, and higher at 3 and 6 months after surgery than that at 1 month after surgery, with statistically significant differences (all P<0.05).With the extension of postoperative time, the monocular and binocular adjustment time and relaxation time gradually shortened, and the shortening gradually decreased and stabilized.Monocular adjustment time and relaxation time were shorter than before surgery at all time points after surgery.The monocular adjustment time was shorter at 1, 3 and 6 months after surgery than that at 1 week after surgery and shorter at 3 and 6 months after surgery than that at 1 month after surgery, and the monocular relaxation time was shorter at 3 and 6 months after surgery than that at 1 week after surgery, and the differences were statistically significant (all P<0.05).The binocular adjustment time was shorter at 1, 3 and 6 months after surgery than before surgery and at 1 week after surgery, shorter at 3 and 6 months after surgery than at 1 month after surgery and the binocular relaxation time was shorter at all time points after surgery than that before surgery, showing statistically significant differences (all P<0.05). Conclusions:After ICL implantation, uncorrected visual acuity, accommodative facility, adjustment time and relaxation time all improve throughout the preoperative period and eventually stabilize.

Background and Aims:Laparoscopic pancreaticoduodenectomy(LPD)has become a preferred approach for periampullary tumors,yet delayed gastric emptying(DGE)remains a frequent complication that hampers postoperative recovery.The nasojejunal feeding tube(NJT)is commonly used for early enteral nutrition,but its impact on DGE is controversial.This study aimed to evaluate whether intraoperative NJT placement increases the risk of DGE after LPD and to assess its influence on postoperative recovery outcomes.Methods:A retrospective cohort of 319 patients who underwent LPD at Provincial Hospital Affiliated to Shandong First Medical University from April 2017 to November 2023 was analyzed.Patients were divided into two groups based on intraoperative NJT placement(NJT group,n=200;non-NJT group,n=119).The incidence of DGE and postoperative outcomes were compared.Multivariate logistic regression and propensity score matching(PSM)were performed to identify independent risk factors for DGE.Results:The incidence of grade B/C DGE was significantly higher in the NJT group than in the non-NJT group(36.5%vs.21.8%,P=0.006).NJT placement was associated with longer postoperative hospital stay and higher hospitalization costs(both P<0.05).Multivariate analysis revealed intraoperative NJT placement(OR=1.960,95%CI=1.142-3.363,P=0.015)and intraoperative blood loss>400 mL(OR=1.921,95%CI=1.155-3.194,P=0.012)as independent risk factors for DGE.These findings were consistent after PSM.Conclusions:Prophylactic intraoperative NJT placement confers no additional benefit for postoperative recovery after LPD and is associated with a higher risk of DGE,prolonged hospitalization,and increased medical costs.Routine NJT placement should therefore be avoided,and individualized strategies should be adopted to minimize postoperative complications and enhance recovery.
