ObjectiveTo investigate the effect of Gelian Tiaotang pills on renal fibrosis in db/db mice based on the nucleotide-binding domain leucine-rich repeat and pyrin domain-containing receptor 3 （NLRP3）/cysteinyl aspartate-specific proteinase （Caspase）-1/gasdermin D （GSDMD） signaling pathway. MethodsForty db/db mice were randomly assigned into model， positive control （0.001 3 g·kg·d^-1 dapagliflozin suspension）， and high-， medium-， and low-dose Gelian Tiaotang pills （3.12， 1.56， and 0.78 g·kg·d^-1 suspension of Gelian Tiaotang pills， respectively） groups， with 8 mice in each group. Eight db/m mice were selected as the normal group. The normal group and model group were given equal volumes of pure water， while the drug interventions groups were administrated with corresponding agents by gavage once a day for 12 consecutive weeks. The general conditions of mice were observed daily. The fasting blood glucose （FBG） and body mass were measured every 4 weeks. Kidneys were weighed after sampling， and the kidney index was calculated. An automatic biochemical analyzer was used to measure the serum levels of triglyceride （TG）， total cholesterol （TC）， serum creatinine （SCr）， and blood urea nitrogen （BUN）. The pathological changes， extracellular matrix deposition， and renal fibrosis degree were examined by hematoxylin-eosin， periodic acid-schiff （PAS）， and Masson staining， respectively. Enzyme-linked immunosorbent assay was employed to measure the levels of interleukin （IL）-1β and IL-18 in the renal tissue. Immunohistochemistry （IHC） was used to detect the localization and expression of fibronectin and collagen Ⅰ in the renal tissue. Western blot was employed to determine the protein levels of NLRP3， Caspase-1， cleaved Caspase-1， GSDMD， and GSDMD-N in the renal tissue. ResultsCompared with the normal group， the model group generally had poor general states and increases in the body mass， kidney weight， kidney index， and levels of FBG， TG， TC， SCr， and BUN （P<0.01）. In addition， glomerular pyknosis， increased matrix， vacuolar degeneration of renal tubular epithelial cells， and interstitial infiltration of inflammatory cells were observed in the model group （P<0.01）， together with rises in the levels of IL-1β and IL-18 in the renal tissue （P<0.01） and up-regulated protein levels of NLRP3， Caspase-1， cleaved Caspase-1， GSDMD， GSDMD-N， fibronectin， and collagen Ⅰ in the renal tissue （P<0.01）. Compared with the model group， 12 weeks of drug interventions reduced the body mass， kidney weight， and kidney index and lowered the levels of FBG， TG， TC， SCr， and BUN in the serum and IL-1β and IL-18 in the renal tissue （P<0.05， P<0.01）. Furthermore， drug interventions ameliorated the renal lesions and down-regulated the protein levels of NLRP3， Caspase-1， cleaved Caspase-1， GSDMD， GSDMD-N， fibronectin， and collagen Ⅰ in the renal tissue （P<0.05， P<0.01）. The high-dose group of Gelian Tiaotang pills had the best effects. ConclusionGelian Tiaotang pills may inhibit pyroptosis and reduce inflammatory responses by regulating the NLRP3/Caspase-1/GSDMD signaling pathway， thus delaying the process of renal fibrosis in diabetes.

BACKGROUND: Lung cancer is currently the most prevalent malignancy and the leading cause of cancer deaths worldwide. Although the early stage non-small cell lung cancer (NSCLC) presents a relatively good prognosis, a considerable number of lung cancer cases are still detected and diagnosed at locally advanced or late stages. Surgical treatment combined with perioperative multimodality treatment is the mainstay of treatment for locally advanced NSCLC and has been shown to improve patient survival. Following the standard methods of neoadjuvant therapy, perioperative management, postoperative adjuvant therapy, and other therapeutic strategies are important for improving patients' prognosis and quality of life. However, controversies remain over the perioperative management of NSCLC and presently consensus and standardized guidelines are lacking for addressing critical clinical issues in multimodality treatment. METHODS: The working group consisted of 125 multidisciplinary experts from thoracic surgery, medical oncology, radiotherapy, epidemiology, and psychology. This guideline was developed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. The clinical questions were collected and selected based on preliminary open-ended questionnaires and subsequent discussions during the Guideline Working Group meetings. PubMed, Web of Science, Cochrane Library, Scopus, and China National Knowledge Infrastructure (CNKI) were searched for available evidence. The GRADE system was used to evaluate the quality of evidence and grade the strengths of recommendations. Finally, the recommendations were developed through a structured consensus-building process. RESULTS: The Guideline Development Group initially collected a total of 62 important clinical questions. After a series of consensus-building conferences, 24 clinical questions were identified and corresponding recommendations were ultimately developed, focusing on neoadjuvant therapy, perioperative management, adjuvant therapy, postoperative psychological rehabilitation, prognosis assement, and follow-up protocols for NSCLC. CONCLUSIONS This guideline puts forward reasonable recommendations focusing on neoadjuvant therapy, perioperative management, adjuvant therapy, postoperative psychological rehabilitation, prognosis assessment, and follow-up protocol of NSCLC. It standardizes perioperative multimodality treatment and provides guidance for clinical practice among thoracic surgeons, medical oncologists, and radiotherapists, aiming to reduce postoperative recurrence, improve patient survival, accelerate recovery, and minimize postoperative complications such as atelectasis.

Objective:To analyze the safety of paclitaxel-based, hyperthermic, intraperitoneal perfusion chemotherapy (HIPEC) after radical resection of locally advanced gastric cancer.Methods:This was a retrospective cohort study of clinicopathological data of 467 patients with locally advanced gastric adenocarcinoma who had been admitted to the Department of Gastrointestinal Surgery, West China Hospital, Sichuan University between July 2019 and April 2021. Among these patients, 151 had undergone radical resection combined with post-operative paclitaxel-based HIPEC (surgery+HIPEC group) and 316 radical resection alone (surgery group). The adverse perioperative events in study patients were evaluated according to the Common Terminology Criteria for Adverse Events (CTCAE 5.0) published by the U.S. Department of Health and Human Services. Subgroup analysis was performed on patients in the surgery+HIPEC group according to the number of times HIPEC was administered and the incidence of adverse events was compared between subgroups using the χ 2 test. Independent risk factors for paclitaxel-based HIPEC-associated adverse events were identified by applying a logistic model. Results:In the surgery+HIPEC group, there were 113 (74.8%) male and 38 (25.2%) female patients of median age 64 (55, 68) years, 18 (11.9%), 79 (52.3%), and 54 (35.8%) of whom had undergone one, two, and three paclitaxel-based HIPEC treatments, respectively, after surgery. The median maximum tumor diameter was 5.0 (3.6, 6.5) cm. In the surgery group, there were 244 (77.2%) male and 72 (22.8%) female patients of median age 63 (54, 68) and the median maximum tumor diameter was 4.0 (3.0, 5.5) cm. In the surgery+HIPEC group, 112 patients (74.2%) had 198 Grade 2 or higher adverse perioperative events, postoperative hypoalbuminemia being the commonest (85 cases, 56.3%), followed by postoperative anemia (50 cases, 33.1%). Compared with the surgery group, the incidences of postoperative hypoalbuminemia (56.3% [85/151] vs. 37.7% [119/316], χ 2=14.420, P<0.001), anemia (33.1% [50/151] vs. 22.5% [71/316], χ 2=6.030, P=0.014), abdominal pain [7.3% [11/151] vs. 1.6% [5/316], χ 2=10.042, P=0.002) and abdominal distension (5.3% [8/151] vs. 1.3% [4/316], χ 2=5.123, P=0.024) were all significantly higher in the surgery+HIPEC group. Analysis of the three HIPEC subgroups revealed significant differences in the incidences of postoperative hypoalbuminemia (13/18 vs. 67.1% [53/79] vs. 35.2% [19/54], χ 2=12.955, P<0.001) and pulmonary infection (6/18 vs. 6.3% [5/79] vs. 1.9% [1/54], χ 2=13.232, P<0.001) between them. Univariate analysis identified body mass index, Borrmann's type and number of HIPEC treatments as associated with perioperative adverse events in the surgery+HIPEC group ( P<0.05). However, according to multifactorial logistic analysis, the above factors were not independent risk factors for perioperative adverse events in the surgery+HIPEC group ( P>0.05). Conclusions:Paclitaxel-based HIPEC after radical resection significantly increases the risk of postoperative hypoalbuminemia, anemia, abdominal pain, and abdominal distension in patients who have undergone excision of locally advanced gastric cancer. However, increasing the frequency of HIPEC treatments did not significantly increase the risk of paclitaxel-based HIPEC-related adverse events. Moreover, univariate and multivariate analysis did not identify any independent risk factors for paclitaxel HIPEC-related adverse events.

Objective:To analyze the performance characteristics of the energy output of defibrillation device at different lifecycle stages of the equipment,and to improve the level of management,so as to ensure the safety and effectiveness of using the device.Methods:A total of 90 defibrillation devices of using 10 types included 861290 and CardioServ(included scrapped devices)during the period of 2015-2022 were retrospectively analyzed.The detected data of energy output of defibrillation device were analyzed as statistical method,and the error of releasing energy was calculated.A total of 36 defibrillation devices that were in the early stages of use(at the first three years of device use)were divided into the first year,the second year and the third year,and the data of energy outputs of devices among three years were compared.The data of the type A and type B defibrillation devices,which were the largest number of devices in the normal stage of use(the middle stage of use),were calibrated according to the energy release in the three years between 2018 and 2000.The difference of releasing energy at the preseted value of 100J between the two types of devices was analyzed.Finally,the errors of energy releases of 8 devices,which energy outputs exceeded the deadline,in the scrap period between 2015 and 2022 were summarized.Results:In the data of three groups of devices in the early stages of use,the differences at the first and second year of device use among 100J,150J and 200J of the energy releases of the preseted values were significant(t=-0.17,-0.17,-0.58,P>0.05).The difference of the measured values between the first and third years of device use was not significant(Z=-0.70,-0.38,-0.86,P>0.05).The results of variance analysis of repeated measurement of the energy releases of the devices in normal stage indicated that the difference of the energy release at 100J preseted point among different types of 41 devices was significant(F=4.40,P<0.05).The energy release of type X defibrillator appeared constantly high,and the relative error increased with the increasing of preseted values.The repeatability of the device was better,and the relationship between preseted energy(x)and release energy(y)conformed to linear relationship(R2=0.9985).In these defibrillation devices that were using,the qualified rate of energy output of>100J preseted point was 97.68%.Conclusion:There is slight difference in the mean value of energy release between different type of defibrillation devices within the qualified range,and the energy release still is a performance indicator that should be highly focused for defibrillation devices.We should combine with the maintenance and repair data of device to conduct in-depth analysis,so as to grasp the operating status of the device,and optimize the strategy of quality control,and ensure the safety of defibrillator in clinical use.

Diabetic kidney disease(DKD)is the leading cause of end-stage renal disease worldwide and one of the major microvascular complications of diabetes.The pathogenesis of DKD is multifactorial,and its pathological process involves multiple pathways.Ferroptosis is a regulatory cell death characterized by iron dependent lipid peroxidation.Recently,an increasing number of studies have shown that ferroptosis is a key driving factor for the occurrence and development of DKD and has been identified to play a crucial role in the occurrence,development,and treatment of various kidney diseases.Traditional Chinese medicine has unique advantages in preventing and delaying the progression of DKD due to the characteristics of multi-component,multi-target,and multi-pathway.This article focuses on summarizing the impact of key regulatory factors and signaling pathways of ferroptosis on the pathological process of DKD,as well as the research progress of traditional Chinese medicine in regulating ferroptosis key factors and pathways for preventing and treating DKD.The aim of this study is to provide new ideas for the clinical treatment of DKD and the development of new traditional Chinese medicine drugs.

OBJECTIVE：To compare the chemical components in Sinapis alba before and after stir-frying. METHODS ： UPLC-Q-Exactive Obitrap MS was adopted to analyze chemical constituents of S. alba before and after stir-frying. The determination was performed on Waters CORTECS T 3 column with mobile phase consisted of methanol- 0.1％ formic acid solution （gradient elution ）at the flow rate of 0.25 mL/min. The column temperature was 30 ℃ and the sample size was 2 μL. High resolution MS adopted heating electrospray electron source ，positive ion scanning mode ，scanning range m/z 120-1 000. The chemical constituents of S. alba before and after stir-frying were identified by Compound Discover 3.2 software combined with relevant database ，and the content changes of chemical constituents were analyzed by using peak area. Chemometrics analysis was performed for the content changes of chemical constituents using peak area as variable. RESULTS ：A total of 54 chemical components were identified in S. alba ，mainly fatty acids （represented by erucic acid ），alkaloids（represented by sinapine ）， flavonoids. After stir-frying ，the contents of 19 chemical components changed significantly ，of which the contents of 10 components decreased significantly and those of 9 components increased significantly （P＜0.05）. Principal component analysis and orthogonal partial least squares discriminant analysis could clearly distinguish S. alba from stir-fried S. alba . CONCLUSIONS ：The contents of some chemical components of S. alba change significantly after stir-frying ，which may be one of the important reasons for the change of efficacy after stir-frying.

Objective: The consistency of 24-hour oropharyngeal Dx-pH monitoring and proton pump inhibitor(PPI) test in the diagnosis of laryngopharyngeal reflux disease (LPRD) was investigated. Methods: Sixty patients with laryngopharyngeal reflux (LPR) related symptoms who had never received PPI treatment were assessed by reflux symptom index (RSI) and reflux finding score (RFS) between October 2017 and October 2018, including 28 males and 38 females, aged from 16 to 72 years, with a medium age of 38 years. Prior to treatment, all patients were evaluated with 24 hours oropharyngeal Dx-pH monitoring(Restech). After empiric therapy with PPI twice-daily for 8 weeks, the efficacy was evaluated according to posttreatment RSI score.The data was analysed with Kruskal-Wallis test, Student Newman Keuls test and consistency check. Results: (1)Among all 60 patients,13 patients (21.7%) had pathologic Ryan score and all resulted responsive to PPI;27 patients (45.0%) with a negative Ryan score were unresponsive to PPI; 20 patients (33.3%) despite a negative Ryan score resulted responsive to PPI therapy. Considering responsiveness to PPI therapy as the gold standard for the diagnosis of LPRD, the sensitivity, specificity, positive predictive value and negative predictive value of Ryan score were 39.4%, 100%, 100% and 57.4% respectively. The Kappa value was 0.369 (P<0.01). (2)Among 34 patients (56.7%) with positive Dx-pH results (24-hour oropharyngeal acid reflux events≥ 3 times), 29 patients were positive and 5 patients were negative in PPI test. Among 26 patients with negative Dx-pH results (24-hour oropharyngeal acid reflux events<3 times), 4 patients were positive and 22 patients were negative in PPI test. Considering responsiveness to PPI therapy as the gold standard for the diagnosis of LPRD, the sensitivity, specificity, positive predictive value and negative predictive value of 24-hour oropharyngeal acid reflux events were 87.9%, 81.5%, 85.3% and 84.6% respectively. The Kappa value was 0.696(P<0.01). Conclusions There is a positive correlation between 24-hour oropharyngeal Dx-pH monitoring positive results (24-hour oropharyngeal acid reflux events≥3 times) and PPI test in the diagnosis of LPRD. The 24-hour oropharyngeal Dx-pH monitoring can be a promising tool for the diagnosis of suspected LPRD patients, and more sensitive and accurate Dx-pH diagnostic index will be required in the clinic.
