Diabetic nephropathy belongs to diabetic microvascular aseptic inflammation， which is the main cause of end-stage renal disease and can cause damage to the structure of glomeruli and tubulointerstitium. Pyroptosis is a potent pro-inflammatory model of programmed cell death mediated by gasdermin （GSDM） protein family， which is characterized by nuclear shrinkage， chromatin DNA fragmentation， plasma membrane rupture， cell swelling and deformation. Related studies have found that pyroptosis is closely related to the occurrence and development of diabetic nephropathy. Inhibition of pyroptosis to a certain extent can reduce diabetic renal injury， so the pathway of pyroptosis involved in the pathogenesis of diabetic nephropathy is the current research focus. The characteristics of multi-components， multi-targets and multi-pathways of traditional Chinese medicine have significant advantages in the treatment of diabetic nephropathy. Some components of traditional Chinese medicine， single traditional Chinese medicine and compound prescription of traditional Chinese medicine can improve diabetic renal injury by inhibiting pyroptosis pathway and related targets. Based on the molecular mechanism of pyroptosis， this paper clarifies the mechanism of pyroptosis in diabetic nephropathy by expounding the relationship between pyroptosis and its pathway targets and diabetic nephropathy. This paper summarizes the research status of traditional Chinese medicine in the treatment of diabetic nephropathy by interfering with related pyroptosis pathways in recent years， so as to provide perspectives and ideas for the prevention， early diagnosis， drug development and molecular treatment of diabetic nephropathy in the future.

Objective To construct an evidence-based practice program of discharge preparation services for hip replacement patients based on the best evidence,and to evaluate its clinical effects,aiming to provide references for the implementation of relevant interventions.Methods Knowledge to Action Framework was used as a guide to summarise the best evidence on discharge preparation services for hip replacement patients and to select services based on clinical context.We selected 38 hip replacement patients and 17 healthcare professionals from the De-partment of Orthopaedic Surgery at a tertiary A hospital in Shanghai in September-October 2023 to conduct a baseline review,identify facilitating and hindering factors,and develop a practice protocol.We also selected 38 hip replacement patients and 17 healthcare professionals from November-December 2023 on this ward for evidence-based practice.Nurses'rates of completion of review indicators,levels of knowledge of discharge preparation ser-vices,and discharge planning competencies were compared before and after practice.Patients'readiness for dis-charge,hip function,and unplanned readmissions were also compared before and after the practice.Results After evidence-based practice,nurses'completion rates of review indicators,knowledge of discharge preparation services,and discharge planning competencies were higher than baseline levels(P＜0.05).Hip replacement patients showed a significant improvement in readiness for discharge and hip function(P＜0.001).Conclusion The implementation of an evidence-based practice program of discharge preparation services improves nurses'knowledge and skills,and also contributes to the discharge readiness and hip function of hip replacement patients.

Objective To study the clinical efficacy of buccal acupuncture in the treatment of refractory tinnitus in the elderly.Methods In this study,50 elderly patients with refractory tinnitus were randomly divided into two groups:the experimental group(n=26)received buccal acupuncture therapy on the neck,upper neck,scapula zone,shoulder,back,mastoid process,thoracic plexus,abdominal plexus and pelvic plexus on the affected side,and the control group(n=24)received sound therapy.After 8 weeks of treatment intervention,the two groups were comprehensively evaluated for the changes in the tinnitus evaluation scale(TEQ),self-rating depression scale(SDS),and blood rheological indexes,including whole blood high-cut viscosity(HSV),plasma viscosity(PSV)and fibrinogen in blood(FIB)clotting.Results After treatment,the total effective rate of the experimental group was 84.6％(22/26),higher than 54.2％(13/24)in the con-trol group.The difference in total effective rate and efficacy level between the two groups was statistically significant(P＜0.05).TEQ and SDS were significantly lower in the two groups compared to pre-treatment(P＜0.05),and HSV,PSV and FIB in the experimental group were significantly lower compared to pre-treatment(P＜0.05).The experimental group demonstrated better post-treatment outcomes in TEQ,SDS,HSV,and FIB compared to the control group(P＜0.05).Conclusion Buccal acupuncture treatment is effective in improving the symptoms of refractory tinnitus in the elderly,relie-ving the depression complicated by tinnitus,and is helpful in changing blood flow resistance and reducing blood coagulation probably.

Alzheimer's disease(AD)is an age-related neurodegenerative disease with an increasing incidence worldwide.A large number of studies have shown that the incidence rates of hearing loss is high in patients with mild cognitive impairment and Alzheimer's disease,and may be a risk factor for the occurrence and development of cognitive impairment.There is an interaction between the two,but the causal mechanism is still unclear.Early screening and management of hearing impairment may play an important role in the early diagnosis,symptom im-provement and disease progression of Alzheimer's disease.This paper reviews relevant clinical and basic research to discuss the correlation between hearing loss and Alzheimer's disease,and the possible causal mechanism between them.

Creutzfeldt-Jakob disease(CJD)is a rapidly progressive and fatal neurodegenerative disorder caused by prions,with certain infectivity and iatrogenic transmission risks.With the rapid progress and application of new dia-gnostic biomarkers and detection methods,as well as the construction and improvement of surveillance and reporting systems,the detection of CJD in patients domestically and internationally has shown an increasing trend year by year.Due to its long incubation period and heterogeneity of early symptoms,early identification and diagnosis of the disease is difficult,increasing the risk of transmission within medical institutions.Currently,there is a lack of con-sensus on the infection prevention and control of CJD.In order to timely identify and diagnose CJD as well as effec-tively block its transmission in medical institutions,this consensus summarizes 15 clinical concerns and formulates 24 specific recommendations based on the latest domestic and international research findings and clinical evidence,as well as combines with clinical practice,aiming to standardize healthcare-associated infection prevention and control measures for CJD and reduce its transmission risk in medical institutions.

Objective:To analyze the disease burden of respiratory syncytial virus (RSV)- associated lower respiratory tract infection (LRTI) in Chinese children under one year of age from 1990 to 2021.Methods:Using the Global Burden of Disease (GBD) 2021 database ( https://vizhub.healthdata.org/gbd-results/), we calculated deaths, mortality, age-standardized mortality rates (ASMR), disability- adjusted life years (DALYs), DALY rates, and age-standardized DALY rates (ASDR) to assess the disease burden of RSV-associated LRTI in Chinese children under one year of age. Joinpoint regression modeling was employed to analyze temporal trends in disease burden in China from 1990 to 2021, with stratification by time, age, and sex. Comparisons were made with global and high socio-demographic index (SDI) regions. Results:In 2021, there were 324 deaths (95% UI: 179-539) from RSV-LRTI in Chinese infants under one year of age, with a mortality rate of 2.82 per 100 000 (95% UI: 1.55-4.69), ASMR of 0.10 per 100 000 (95% UI: 0.06-0.16), DALYs of 29 131.28 years (95% UI: 16 050.27-48 398.30), DALY rate of 253.56 per 100 000 (95% UI: 139.70-421.26), and ASDR of 6.70 per 100 000 (95% UI: 3.72-11.12). All metrics were lower than global levels but significantly higher than high-SDI regions. From 1990 to 2021, substantial reductions were observed in deaths, mortality rates, DALYs, and DALY rates of RSV-LRTI among children under one year of age in China, globally, and in high-SDI regions. China achieved ASMR and ASDR reductions of－95.91% (95% CI:－97.75% to－92.96%) and－96.70% (95% CI:－98.19% to－94.33%), comparable to high-SDI regions but exceeding global averages. Joinpoint analysis showed average annual percentage changes (AAPC) in ASMR of－9.80% (95% CI:－10.45% to－9.14%) for China,－5.38% (95% CI:－5.83% to－4.91%) globally, and－7.13% (95% CI:－9.07% to－5.14%) for high-SDI regions (all P<0.001). The AAPC for ASDR were－10.41% (95% CI:－11.01% to－9.79%),－5.40% (95% CI:－5.82% to－4.97%), and－7.09% (95% CI:－9.70% to－4.41%) for China, the global average, and high-SDI regions, respectively, with the most pronounced decline occurring between 2019 and 2021 (ASMR decreased by 53.33%, 45.81%, and 61.31%, while ASDR declined by 52.50%, 44.54%, and 58.88% in China, globally, and in high-SDI regions, respectively). In 2021, both China and high-SDI regions exhibited declining mortality and DALY rates for RSV-LRTI with increasing age among children under one year, while neonates younger than 28 days consistently demonstrated the highest burden metrics. The rate of decline was comparable between China and high-SDI regions, with both exceeding the global average. Furthermore, from 1990 to 2021, male infants under one year of age in China, globally, and in high-SDI regions consistently showed higher overall trends in deaths, mortality rates, DALY, and DALY rates for RSV-LRTI compared to female infants. Conclusions:Although China's RSV-LRTI disease burden in infants under one year remains lower than global levels but higher than high-SDI regions, the country achieved reduction rates comparable to high-SDI regions, exceeding global averages. RSV-LRTI continue to pose significant health threats to neonates and male infants, necessitating age-specific and sex-specific prevention strategies.

Objective:To investigate the prognostic value of circulating plasma cell (CPC) in patients with newly diagnosed multiple myeloma (NDMM) undergoing induction therapy with bortezomib, lenalidomide, and dexamethasone (VRD) regimen.Methods:This study retrospectively analyzed clinical data of 152 patients with NDMM treated with the VRD regimen as induction therapy in the Hematology Department of Jiangsu Provincial People’s Hospital from January 2019 to March 2024. The clinical characteristics, efficacy, and prognosis of patients with high and low CPC proportions are compared. The prognosis of patients in the CPC-positive group, CPC-negative conversion group, and CPC-negative group was analyzed.Results:This study included 152 patients with NDMM, comprising 76 males and 76 females, with a median age at onset of 62 (40–77) years. Compared with the group with CPC proportion of <0.105%, patients with CPC proportion of ≥0.105% demonstrated a higher proportion of International Staging System (ISS) stage Ⅲ ( P<0.001), Revised ISS stage Ⅲ ( P=0.023), HGB≤100 g/L ( P=0.015), β 2-microglobulin ≥3.5 g/L ( P<0.001), shorter median progression-free survival (PFS) period (24 months vs 52 months, P<0.001), and shorter median overall survival (OS) period (52 months vs not achieved, P=0.005). Patients in the CPC-negative group demonstrated a longer median PFS period (not reached vs 41 months vs 19 months, P<0.001) and median OS period (not reached vs not reached vs 26 months, P<0.001) compared with patients in the CPC-negative conversion group and CPC-positive group. Multivariate analysis revealed CPC proportion of ≥0.105% ( HR=3.79, 95% CI: 1.95–7.38, P<0.001), positive CPC after induction therapy ( HR=3.54, 95% CI: 1.41–8.87, P=0.007), and cytogenetic high risk ( HR=3.69, 95% CI: 1.85–7.37, P<0.001) as independent risk factors affecting the PFS of patients. Meanwhile, CPC of ≥0.105% ( HR=3.50, 95% CI: 1.29–9.48, P=0.014) and positive CPC after induction therapy ( HR=4.12, 95% CI: 1.13–15.03, P=0.032) are independent risk factors affecting the OS of patients. Conclusion:Patients with NDMM demonstrating high CPC expression have a worse prognosis, with CPC level as an independent prognostic factor.

To retrospectively analyze the clinical data of 465 newly diagnosed patients with multiple myeloma (NDMM) admitted to the First Affiliated Hospital of Nanjing Medical University from December 2016 to December 2024, and compare the prognostic value of high-risk cytogenetic abnormalities (HRCAs) in NDMM patients under mSMART 3.0 and mSMART 4.0 risk stratification systems. The results showed that in both stratification systems, the prognosis of high-risk patients was worse than that of standard-risk patients. Moreover, a higher number of HRCAs was associated with a worse prognosis. The mSMART 4.0 system, which considers the coexistence of various cytogenetic abnormalities, provides a more precise definition of HRCA than mSMART 3.0. It demonstrates a superior ability to differentiate between different categories of cytogenetic risk.
