Diabetic kidney disease（DKD） is a chronic kidney structural and functional disorder caused by diabetes. With the global prevalence of diabetes continuing to rise， DKD has gradually become a major cause of chronic kidney disease and end-stage renal disease（ESRD）， posing a serious threat to patients' quality of life and long-term health outcomes. Studies have shown that apoptosis plays a pivotal role in the development and progression of DKD， with its mechanisms involving abnormal activation of multiple signaling pathways such as Toll-like receptor 4（TLR4）/nuclear transcription factor-κB（NF-κB）/B-cell lymphoma-2（Bcl-2）/cysteinyl aspartate-specific proteinase（Caspase）-3， protein kinase R-like endoplasmic reticulum kinase（PERK）/eukaryotic initiation factor 2α（eIF2α）/activating transcript factor 4（ATF4）/CCAAT enhancer-binding protein homologous protein（CHOP）， phosphatidylinositol 3-kinase（PI3K）/protein kinase B（Akt）/glycogen synthase kinase-3β（GSK-3β）， Janus kinase 2（JAK2）/signal transducer and activator of transcription 3（STAT3）， adenosine monophosphate-activated protein kinase（AMPK）/mammalian target of rapamycin（mTOR） and silent information regulator 1（SIRT1）/tumor suppressor protein 53（p53）， thereby accelerating renal pathological damage in DKD. Extensive evidence-based medical studies have confirmed that traditional Chinese medicine（TCM）， leveraging its unique therapeutic advantages of multi-target， multi-component and multi-pathway approaches， has demonstrated remarkable efficacy and favorable safety profiles in treating DKD. Recent studies have demonstrated that active components of TCM can specifically target and modulate key effectors in apoptotic signaling pathways. Meanwhile， traditional compound formulations exert synergistic effects through multiple approaches such as replenishing deficiency and activating blood circulation， detoxifying and dredging collaterals， tonifying kidney essence， and removing stasis and purging turbidity， thereby comprehensively regulating critical pathological processes including endoplasmic reticulum stress and mitochondrial apoptosis pathways. This combined therapeutic approach of molecular targeting and holistic regulation provides novel strategies for delaying the progression of DKD. Based on this， this paper provides an in-depth analysis of key apoptotic signaling pathways and their regulatory mechanisms， while systematically summarizing recent research advances regarding the therapeutic effects of TCM active components， compound formulations， and proprietary Chinese medicines on DKD through modulation of these pathways， with particular emphasis on their underlying molecular mechanisms. These findings not only elucidate the modern scientific connotation and theoretical basis of TCM in treating DKD but also establish a solid theoretical and practical foundation for promoting the wider clinical application and further research of TCM in the field of DKD treatment.

Objective To investigate the expression characteristics of c-MET protein in colorectal cancer (CRC) and its associations with clinicopathological parameters, MET gene amplification status, and prognosis, and to evaluate the concordance between immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) detection strategies, thereby providing evidence for patient selection for MET-targeted therapy. Methods A total of 193 formalin-fixed paraffin-embedded (FFPE) tissue samples from CRC patients were collected. Immunohistochemistry (IHC) was used to detect c-MET protein expression, and fluorescence in situ hybridization (FISH) was performed to evaluate MET gene amplification status. The associations between c-MET protein expression and clinicopathological characteristics, including KRAS, NRAS, and BRAF mutation status, as well as progression-free survival (PFS), were analyzed. The concordance between IHC and FISH detection results was also evaluated. Results c-MET protein expression was significantly higher in tumor tissues than in adjacent normal tissues (P<0.05). Significant differences in c-MET expression were observed between primary tumors and liver or peritoneal/pelvic metastatic lesions (P<0.05). The proportion of high c-MET expression was significantly higher in KRAS-mutant patients than in KRAS wild-type patients (41.38% vs. 16.92%, P<0.05). The MET gene amplification rate was 8.29% (16/193), including clustered or diffuse amplification in 1.55% (3/193) and heterogeneous amplification in 6.74% (13/193). No MET exon 14 skipping mutation or amplification was detected by next-generation sequencing (NGS). Using an IHC H-Score≥150 as the threshold, the positive percent agreement (PPA) between IHC-detected c-MET protein expression and FISH-detected MET gene amplification was 100%. All clustered MET amplification regions exhibited diffuse strong c-MET expression (IHC 3+). No statistically significant association was observed between c-MET expression level and PFS (P>0.05). Conclusion High c-MET expression may represent a potential therapeutic target for KRAS-mutant CRC patients. An H-Score ≥150 is recommended as the initial screening threshold to rapidly identify patients suitable for MET-targeted therapy, with FISH testing when necessary. Diffuse strong c-MET expression (IHC 3+) shows high concordance with clustered MET gene amplification.

Objective To investigate the distribution characteristics and future trends of clinical trials related to TCM prevention and treatment of constipation by analyzing the clinical trials registered in the Chinese Clinical Trial Registry(ChiCTR).Methods The clinical trials data related to TCM prevention and treatment of constipation in the ChiCTR database were retrieved from the establishment of the database to April 15,2024.Excel 2019 was utilized for de-duplication.Subsequently,SPSS 26.0 was employed to analyze the general characteristics,research types,intervention measures,etc.of the included trials,charts were drawn,and the clinical trial characteristics were summarized.Results A total of 107 clinical trials were included,with 102 being pre-registered,involving 21 provincial-level administrative regions and 75 clinical institutions.The top five regions in terms of the number of registered clinical trials were Beijing(19.63%),Shanghai(15.89%),Guangdong(14.02%),Sichuan(10.28%)and Jiangsu(9.35%).The top three sources of funding were local finance(28.97%),self-raised funds(18.69%)and hospital-funded funds(15.89%).The research types were mostly intervention studies(92.52%),of which 41 explicitly stated the use of blinding methods,and the main research design type is randomized parallel controlled trial.Conclusion The number of clinical trials related to TCM prevention and treatment of constipation registered in ChiCTR is on an upward trend.However,there is a noticeable geographical imbalance in the distribution of these trials,and there is a need for further improvement in the quality of trial design and the standardization of registration information.

OBJECTIVE To formulate an expert consensus on the prevention and control of respiratory infectious diseases in railway stations and trains in China,and to standardize the prevention and control of respiratory infec-tious diseases in railway stations and trains scientifically.METHODS The government authorities organized multi-ple prevention and control experts from transportation,medical care and prevention fields to conduct in-depth re-search through methods such as meetings and on-site investigations,and combined with their practical experi-ence in this field to formulate this expert consensus.RESULTS In-depth studies were conducted on the prevention and control strategies,measures and emergency response system construction of respiratory infectious diseases in railway stations and trains,and this expert consensus was formed.CONCLUSION This expert consensus supple-ments improves the existing prevention and control system for respiratory infectious diseases in railway stations and trains,and provides an important reference basis for the prevention and control of respiratory infectious disea-ses in railway stations and trains.

Objective To compare the differences in clinical features and treatment choices between periph-eral spondyloarthritis(pSpA)and axial spondyloarthritis(axSpA),and better understand the clinical charac-teristics and medication needs of pSpA.Methods Our study is a retrospective cohort study.The patients who first visited the First Medical Center of Chinese PLA General Hospital between January 2016 and December 2022 and were diagnosed with axSpA or pSpA according to the classification criteria established by the Assess-ment of SpondyloArthritis International Society were selected as the study subjects.Demographic data,clinical characteristics,laboratory tests,and treatment information of these patients were obtained through the electronic medical records management system and the intelligent management system for spondyloarthritis.The research compared the distribution of swollen and tender joints between pSpA and axSpA patients,as well as that between pSpA1(excluding patients with psoriatic arthritis)and axSpA patients.Additionally,we analyzed differences in clinical features and treatment options among these groups.Results A total of 1639 pa-tients were included in the study,of which 184 had pSpA(including 97 with psoriatic arthritis),and 1455 had axSpA.Compared to axSpA patients,pSpA patients had fewer male patients(62.5％vs.79.7％,P＜0.001),later onset age(33.8 years vs.22.0 years,P＜0.001),shorter diagnostic delays(6.0 months vs.14.2 months,P=0.004),more associated peripheral arthritis(71.7％vs.9.3％,P＜0.001)and dac-tylitis(6.5％vs.0.3％,P＜0.001),more cases of psoriasis(52.7％vs.1.1％,P＜0.001)and a more common family history of psoriasis(11.4％vs.3.4％,P＜0.001).pSpA patients had higher levels of in-flammatory markers but a lower positive rate of human leukocyte antigen(HLA)-B27(43.5％vs.87.4％,P＜0.001).A positive HLA-B27 was associated with an earlier onset age,fewer cases of psoriasis,and a fami-ly history of ankylosing spondylitis.pSpA patients had a higher proportion of using conventional synthetic dis-ease-modifying antirheumatic drugs(csDMARDs),biologic disease-modifying antirheumatic drugs(bDMARDs),and oral glucocorticoids,and they also more frequently used a combination of bDMARDs and csDMARDs(19.0％vs.12.2％,P=0.009)or multiple csDMARDs(65.8％vs.12.5％,P＜0.001).Compared to axSpA patients,pSpA1 patients(excluding psoriatic arthritis)did not show significant differences in the prevalence of psoriasis,uveitis,family history of psoriasis,or the use of bDMARDs,but the subgroup analysis of other variables was consistent with the results of pSpA patients.Conclusions pSpA patients tend to have a later onset of disease,a lower proportion of male and HLA-B27 positivity,more associ-ated peripheral arthritis,dactylitis,psoriasis,and a more common family history of psoriasis.The disease bur-den in terms of treatment for pSpA is not lower than that for axSpA.Due to the presence of more peripheral symptoms,psoriasis,and higher levels of inflammation,they also require more medication.

Objective To systematically evaluate the published models in prediction of the risk of lung infections in elderly patients with hip fracture so as to provide a guidance for medical workers in selection or development of suitable risk prediction models.Methods Relevant studies were searched from databases including CNKI,Wanfang Data,VIP,SinoMed,PubMed,Web of Science,Cochrane Library,Embase and CINAHL,from the inception to 31st January,2024.Data were extracted from the selected literature and a bias assessment tool of risk predictive model was used to evaluate the risk of bias and applicability of the included literature.Results A total of 1,035 articles were retrieved,of which seven studies involving 13 predictive models were finally included after screening.The sample sizes ranged from 305 to 2,669 cases and lung infection rates ranged from 5.40%to 20.02%.The repeatedly reported predictors included age,gender,chronic obstructive pulmonary disease,hypoproteinaemia,American Society of Anesthesiologists(ASA)Physical Status Classification and white blood cell count.In the 13 models constructed,the reported area under the curve(AUC)of subjects'job characteristics ranged from 0.667 to 0.996.Five out of seven studies had good overall applicability,but all with high risk of bias.Conclusion The predictive models for lung infections in elderly patients with hip fracture are still in the stage of development.Although the predictive models show some predictive performance,however they are still deficient,and all studies have been found with a high risk in bias.

Objective To analyze the current status of clinical trial registration of common anorectal diseases in Chinese Clinical Trial Registry(ChiCTR)and the research of TCM.Methods The ChiCTR database was retrieved to collect and organize clinical trials related to hemorrhoids,anal fissures,anal fistulas,perianal abscesses,and perianal eczema.The retrieval time was from the establishment of the database to December 10,2023.Characterization of included registration trials was analyzed.Results A total of 148 registered projects were included,75 of which were TCM-related clinical trials.Among them,134 clinical trials were pre-registered and 121 passed the ethical review.Shanghai,Jiangsu,Guangdong,Beijing and Sichuan accounted for 76.35％of the total number of registrations,and the largest number of registered projects was in Shuguang Hospital affiliated with Shanghai University of Traditional Chinese Medicine.The top 3 funding sources were local finance,self-funding and hospital funding.The registered projects were mainly intervention studies.114 studies used randomized methods and 34 studies were blinded.Conclusion At present,the number of ChiCTR-registered clinical trials on anorectal diseases is on an increasing trend,and the treatment of anorectal diseases with TCM has obvious characteristics.However,there are cases of irregular filling of registration content and uneven regional distribution.

Objective:This study aims to explore the predictive value of the ratio of caliceal pelvic height to infundibular length（CPH/IL）for the stone-free rate（SFR）in the treatment of lower calyx stones using flexible ureteroscopic lithotripsy（FURL）combined with a distally bendable negative pressure suction sheath.Methods:A retrospective analysis was conducted on the clinical data and anatomical parameters of 312 patients with lower calyx stones or combined lower calyx stones admitted to the Third Xiangya Hospital of Central South University from September 2022 to December 2023，all of whom were treated with FURL combined with a distally bendable negative pressure suction sheath. Stone clearance was defined as no residual stones or residual stones with a diameter of ≤3 mm without any symptoms. Patients were divided into the clearance group（265 cases，84.90%）and the non-clearance group（47 cases，15.10%）. There were no significant differences in gender（male/female：173/92 cases vs. 29/18 cases），age［（44.69 ± 13.14）years vs.（42.60 ± 10.93）years］，degree of hydronephrosis（no hydronephrosis/mild hydronephrosis/moderate to severe hydronephrosis：122/85/58 cases vs. 21/12/14 cases），side of lower calyx stones（left/right：157/108 cases vs. 31/16 cases），maximum diameter of stones（MDS）［（19.23 ± 6.41）mm vs.（17.77 ± 6.18）mm］，and CT value of stones［（993.46 ± 249.12）Hu vs.（1013.43 ± 300.90）Hu］between the two groups（ P > 0.05），indicating comparability between groups. There was no significant difference in the distance from the midpoint of the lower lip of the renal pelvis to the ureter at the lowest plane of the lower calyx（K-A line）between the clearance and non-clearance groups［（26.16 ± 5.18）mm vs.（25.70 ± 8.66）mm， P > 0.05］. However，significant differences were observed in the infundibulopelvic angle（IPA）［（53.97 ± 15.72）° vs.（37.43 ± 15.39）°］，infundibular length（IL）［（27.26 ± 5.11）mm vs.（33.04 ± 7.38）mm］，infundibular width（IW）［（8.27 ± 2.82）mm vs.（7.09 ± 3.20）mm］，caliceal pelvic height（CPH）［（19.96 ± 4.63）mm vs.（30.32 ± 7.56）mm］，ureter-lower calyx distance（ULD）［（23.00 ± 5.59）mm vs.（18.78 ± 6.31）mm］，CPH/IL ratio［（0.73 ± 0.11）vs.（0.92 ± 0.09）］，and curvature of the lower calyx of the renal pelvis［（0.06 ± 0.01）mm -1 vs.（0.08 ± 0.03）mm -1］between the two groups（ P <0.05）. Univariate and logistic multivariate regression analyses were used to identify the independent risk factors affecting the postoperative SFR of FURL-treated lower calyx stones and to assess the value of CPH/IL for SFR in the treatment of lower calyx stones using FURL combined with a distally bendable negative pressure suction sheath. A logistic multivariate regression model and a corresponding nomogram were constructed，and the predictive ability of the model for SFR was evaluated using the receiver operating characteristic（ROC）curve. The calibration curve and the Hosmer -Lemeshow test were used to assess the consistency and accuracy of the model. The clinical utility of the model was evaluated using decision curve analysis（DCA）. Results:Univariate analysis revealed that seven anatomical parameters differed significantly between the clearance and non-clearance groups（all P < 0.05）：infundibulopelvic angle（IPA， OR = 0.27，95% CI 0.17-0.42， P < 0.01），infundibular length（IL， OR = 2.52，95% CI 1.83-3.47， P < 0.01），infundibular width（IW， OR = 0.64，95% CI 0.45-0.90， P = 0.011），caliceal pelvic height（CPH， OR = 5.78，95% CI 3.67-9.10， P < 0.01），ureter-lower calyx distance（ULD， OR = 0.43，95% CI 0.30-0.63， P < 0.01），CPH/IL ratio（ OR = 13.62，95% CI 6.86-27.03， P < 0.01），and curvature of the lower calyx of the renal pelvis（ O = 3.15，95% CI 2.08-4.78， P < 0.01）. Multivariate logistic regression further identified CPH/IL（ OR = 9.87，95% CI 4.92-19.79， P < 0.01），IPA（ OR = 0.41，95% CI 0.23-0.71， P = 0.001），and ULD（ OR = 0.50，95% CI 0.29-0.87， P = 0.014）as independent risk factors influencing the stone-free rate after flexible ureteroscopic lithotripsy combined with a distally bendable negative-pressure suction sheath. The area under the ROC curve（AUC）of the univariate regression model showed that for IPA，the AUC was 0.788（95% CI 0.711-0.864）；for IL，it was 0.731（95% CI 0.643-0.819）；for ULD，it was 0.677（95% CI 0.586-0.767）；for CPH，it was 0.867（95% CI 0.804-0.929）；for IW，it was 0.628（95% CI 0.535-0.721）；for CPH/IL，it was 0.906（95% CI 0.850-0.961）with an optimal cutoff value of 0.882，corresponding to a sensitivity of 83.02% and a specificity of 92.08%；and for curvature of the lower calyx of the renal pelvis，it was 0.744（95% CI 0.662-0.827）. The AUC of the multivariate regression model was 0.929（95% CI 0.884-0.974）with an optimal cutoff value of 0.364，corresponding to a sensitivity of 82.98% and a specificity of 95.09%. Calibration curves demonstrated close agreement between the predicted and actual stone-free rates after FURL（C-index = 0.921）. The Hosmer-Lemeshow goodness-of-fit test indicated no significant discrepancy between predicted and observed probabilities（ P = 0.135，>0.05）. Decision-curve analysis further revealed that basing clinical decisions on the model ，s predicted probability yields a higher net clinical benefit than either withholding FURL for all patients or treating all patients regardless of risk，and it also outperforms strategies guided by any single independent predictor alone. Conclusions:IPA，IL，IW，CPH，ULD，CPH/IL ratio，and curvature of the lower calyx of the renal pelvis can all predict the postoperative SFR of FURL combined with a distally bendable negative pressure suction sheath for the treatment of lower calyx stones to varying degrees. Among them，CPH/IL has the highest predictive value. When CPH/IL >0.88，it may be difficult to use FURL to treat lower calyx stones.

Objective:To evaluate the efficacy and feasibility of a domestically developed robotic surgical system based on fiber-optic dedicated line communication in cross-regional urological telesurgery.Methods:This was multicenter，single-arm，retrospective case series study. The data of patients who underwent urological telesurgeries using the telesurgical system between January 2023 and December 2024 were analyzed. The cohort included 59 patients from seven hospitals across China. Among the patients，47 were male（79.7%）and 12 were female（20.3%），with a median age of 63.0（56.0，68.0）years and a body mass index of（24.7 ± 3.0）kg/m 2. Surgical procedures included 32 radical prostatectomies，24 partial nephrectomies，one radical nephrectomy，one adrenalectomy，and one ureteral reconstruction. The perioperative indicators，pathological results and postoperative complications were analyzed. The network monitoring data were collected，and the perioperative data of patients，remote system monitoring data and costs were compared between the two communication modes of optical transport network（OTN）and cloud-connect network（CCN）. Results:All 59 remote surgeries were successfully completed，with a mean operative time of（138.0 ± 54.0）minutes，median intraoperative blood loss of 50.0（30.0，100.0）ml and a postoperative hospital stay of 5.0（4.0，6.0）days. No cases required reoperation，Clavien-Dindo grade ≥3 complications，or readmission. The geographical distance between the primary and remote surgical sites ranged from 450 to 2 800 km. Network monitoring revealed increased bidirectional latency with distance increasing：the shortest latency time（Hefei-Hangzhou，450 km）was（16.59 ± 0.80）ms，while the longest（Harbin-Hangzhou，2 200 km）latency time was（53.31 ± 0.31）ms. Average frame loss per procedure was 0?1.27 frames. The results of subgroup analysis comparing OTN and CCN communication modes showed no significant differences in operative time［（130.7 ± 70.5）minutes vs.（142.1 ± 42.9）minutes， P = 0.442］，postoperative hospitalization［6.0（4.0，8.0）d vs. 5.0（4.0，6.0）d， P = 0.581］，or readmission rates（0 vs. 0）. However，CCN demonstrated significant cost advantages with 500 RMB per operation vs. 3 000 RMB per operation for OTN. Conclusions:Urological telesurgery using fiber-optic communication is feasible. The CCN mode，with its cost-effectiveness，excellent usability，and multi-point interconnection flexibility，is currently the preferred communication model for telesurgical applications.

To investigate the pathogenic mechanisms of a patient with type 1 diabetes mellitus (T1DM) complicated with fibrocalculous pancreatic diabetes at Tianjin Medical University General Hospital Airport Site in June 2024, clinical and genetic characteristic analyses were performed. Potential pathogenic genes were screened by whole-exome sequencing (WES), and Sanger sequencing validated the identified genetic variants within the family. The proband exhibited elevated blood glucose levels and positivity for tyrosine phosphatase antibodies, suggesting a diagnosis of T1DM. Multiple calcifications in the pancreas were observed in the proband. Genetic testing revealed that the proband carried two variants in the serine peptidase inhibitor Kazal type 1 (SPINK1) gene, namely, c.194+2T>C and c.-215G>A. According to the American College of Medical Genetics and Genomics (ACMG) guidelines, the c.194+2T>C mutation is preliminarily classified as pathogenic, while the c.-215G>A variant is classified as a variant of uncertain significance (VUS). Bioinformatics analysis indicated that the c.194+2T>C variant in the SPINK1 gene results in a truncated protein, affecting the three-dimensional structure and activity of the protein. This mutation is in complete linkage disequilibrium with the c.-215G>A variant, which may have a protective function and influence the clinical phenotype. Given that the patient also has T1DM and FCPD, there should be increased awareness of the co-occurrence of both types of diabetes to prevent misdiagnosis and underdiagnosis.
