OBJECTIVE:Postoperative recurrence is a common complication of percutaneous endoscopic lumbar discectomy for lumbar disc herniation,which can significantly increase the risk of reoperation.A well-performing risk prediction model can help identify high-risk groups early and prevent postoperative recurrence.This study systematically evaluated the risk prediction model for postoperative recurrence after percutaneous endoscopic lumbar discectomy to provide a reference for surgical decision-making.METHODS:The PubMed,Embase,Web of Science,CNKI,WanFang Data,VIP,and CBM were electronically searched to collect studies on the recurrence risk prediction models after percutaneous endoscopic lumbar discectomy from inception to July 1,2024.Two reviewers independently screened the literature and extracted data.The models' risk of bias,applicability,and report quality were assessed using prediction model risk of bias assessment tool(PROBAST)and Transparent Reporting of a Multivariable Prediction Model for Individual Prognosis or Diagnosis(TRIPOD)tools,respectively.Meta-analysis of postoperative recurrence rate of percutaneous endoscopic lumbar discectomy and related predictors was performed using Revman 5.4 software.RESULTS:(1)A total of 15 studies were included,all of which were retrospective studies,including 24 models for predicting the risk of recurrence after percutaneous endoscopic lumbar discectomy.(2)The PROBAST evaluation results indicated that all 15 studies exhibited a high risk of bias.Regarding applicability,two studies demonstrated a low risk,while 13 presented a high risk.(3)Regarding the TRIPOD reporting quality,the overall quality across the 15 studies was low.The primary reasons for this low compliance included the failure to report blinding,a lack of explanation for the sample size calculation method,lack of detailed description of missing data processing methods,and lack of information such as introduction to the model used.(4)Furthermore,the area under the receiver operating characteristic curve for the model ranged from 0.684 to 0.972,with the number of potential predictor variables varying from 15 to 28.(5)The results of meta-analysis showed that the postoperative recurrence rate of lumbar disc herniation patients treated with percutaneous endoscopic lumbar discectomy was 12%(95%CI=9.0%-15.0%),Modic changes(OR=6.72,95%CI=3.90-11.59),body mass index(OR=1.28,95%CI=1.10-1.49),work intensity(OR=3.22,95%CI=1.85-5.59),age(OR=2.28,95%CI=1.50-3.48),and smoking history(OR=2.65,95%CI=1.75-4.00)were independent influencing factors for postoperative recurrence of percutaneous endoscopic lumbar discectomy(all P<0.05).CONCLUSION:The overall predictive performance of the recurrence risk prediction models after percutaneous endoscopic lumbar discectomy is satisfactory;however,the model exhibits a high overall risk of bias and applicability,coupled with low reporting quality.Additionally,there is a lack of prospective research and external validation.Future,risk prediction models should consider factors such as Modic changes,body mass index,work intensity,age,and smoking history as potential predictors.

3.A case of colorectal cancer with urinary tract infection induced by bayberry pits
World Journal of Emergency Medicine 2025;16(5):514-515
Colorectal cancer is a common tumor of the digestive system and is the third leading cause of cancer-related death worldwide. The global incidence of colorectal cancer is currently increasing. In some patients, the tumor has already spread to nearby organs at the time of diagnosis, with the small intestine and bladder being common sites of invasion.[1,2] The diagnosis of colorectal cancer that has spread to the bladder can be challenging. Aside from a few patients who experience urinary symptoms due to invasion of the bladder trigone or the entire bladder wall, there are no distinct clinical signs, which often leads to misdiagnosis. The following case report details one such instance.

OBJECTIVE To develop the quality evaluation standard indicator system for hospital cough and wheeze pharmaceutical care clinic (CWPC) pharmacist training within the layered learning practice model (LLPM), and apply it in clinical practice. METHODS Our teaching team established an LLPM model to train cough and wheeze pharmacists, according to the actual conditions of our college. Using qualitative interview methods, expert questionnaires were compiled with literature research; the expert correspondence methods were employed to conduct two rounds of consultation with 10 domestic respiratory medicine experts, thus constructing an evaluation index system for the teaching quality of cough and wheeze pharmacists. The experts’ positive coefficient, authority coefficient, Kendall’s harmony coefficient, and the degree of concentration of opinions were calculated. The analytic hierarchy process (AHP) was used to determine the weight of each indicator within the index system. From June 2023 to June 2024, the teaching team enrolled 21 pharmacists in the training program. The teaching team assessed and scored the trial group (LLPM) and control group (traditional teaching model) based on the benefit indicators for pharmacists and patients in the evaluation index system, and compared the results. RESULTS This study explored the establishment of a training system for cough and wheeze pharmacists under the LLPM model, and initially established an evaluation index system using the Delphi method. In two rounds of Delphi method questionnaires, the recovery rate was 100%, with an authority coefficient exceeding 0.8, Kendall’s harmony coefficient ranging from 0.235 to 0.459, and all P-values being less than 0.05. Four primary (comprising trainee feedback, learning gains, behavioral improvements, and training performance), 12 secondary and 33 tertiary indicators were finalized. In the empirical evaluation, the results of the two groups showed a significant benefit to the pharmacists in the trial group. Specifically, the percentage of patients receiving corticosteroids for COPD or wheeze service patients per month (80.5%), an average increase in the number of cough and wheeze team service outpatient visits per month (compared to the same period of the previous year) of 14.8 visits per month, and the patient satisfaction score (4.9) were all significantly higher than those in the control group (P<0.05). CONCLUSIONS The application of the LLPM in competency training for pharmacists specializing in cough and wheeze care yields multiple benefits and holds significant guiding value. The constructed training quality evaluation index system under this model is scientific and reliable.

Liver fibrosis is a vital cause of morbidity in patients with liver diseases and developing novel anti-fibrotic drugs is imperative. Isovalerylspiramycin I (ISP I) as a major component of carrimycin applied to upper respiratory infections, was first found to possess anti-fibrotic potential. The present study aims to evaluate the functions and mechanisms of ISP I in protecting against liver fibrosis. According to our results, ISP I not only reduced the expressions of fibrogenic markers in LX-2 cells but also appeared great protective effects on liver injury and liver fibrosis in bile duct ligation (BDL) rats and carbon tetrachloride (CCl4) mice. We proved that nucleotide-binding protein 2 (NUBP2) was the direct target of ISP I. ISP I through targeting NUBP2, increased the amount of vascular non-inflammatory molecule-1 (VNN1) on the cell membrane, which will inhibit oxidative stress and fibrosis. Simultaneously, the original carrimycin's protective effect on liver damage and fibrosis was verified. Therefore, our study provides potential agents for patients with liver fibrosis-related diseases, and the clear mechanism supports wide application in the clinic.
