Objective To explore the effects of sacral neuromodulation (SNM) on urodynamic parameters during the storage phase in patients with neurogenic bladder (NB), so as to provide reference for evaluating the efficacy of SNM. Methods A total 49 NB patients undergoing SNM at our hospital during Oct.2012 and May 2025 were enrolled. Baseline data and video-urodynamic parameters were collected. Changes in maximum cystometric capacity, maximum detrusor pressure during storage phase, and bladder compliance before and after treatment were assessed. Improvements in detrusor overactivity (DO) and vesicoureteral reflux (VUR) were also analyzed. Results Among the 49 patients,27 were male and 22 were female, with a mean age of (37.41±15.15) years, a median disease duration of 5.0 (2.0,15.5) years, and a median follow-up of 11 (1,32) months. Up to 37 patients (75.5%) received permanent sacral nerve pulse generator implantation (permanent implant group), while the remaining 12 were classified as the non-permanent implant group. Before and after the test period, all patients showed a significant increase in maximum cystometric capacity [ (218.0 (93.0,358.5) mL vs.300.0 (238.5, 400.0) mL, P<0.001], a decrease in maximum detrusor pressure during the filling phase [32.0 (13.5,71.0) cmH_2 O vs. 20.0 (9.0,50.0) cmH_2 O, P<0.001], and an improvement in bladder compliance [11.8 (8.3,25.6) mL/cmH_2 O vs.26.7 (8.6,44.1) mL/cmH_2O, P<0.001]. In the permanent implant group, comparisons before and after the test period showed an increase in maximum bladder capacity [ (239.16±147.23) mL vs. (312.24±121.83) mL, P<0.001], a decrease in maximum detrusor pressure during filling[32.0 (15.0,58.0) cmH_2 O vs.15.0 (9.0,41.0) cmH_2 O, P<0.05], and improved bladder compliance [10.8 (8.3,23.6) mL/cmH_2 O vs.28.6 (8.6,41.4) mL/cmH_2 O, P<0.001]. No statistically significant differences in these parameters before and after the test period were observed in the non-permanent implant group (P>0.05). A total of 17 patients in the permanent implant group underwent follow-up video urodynamics. Compared to pre-test values, significant improvements were observed in maximum detrusor pressure during filling, and bladder compliance both at the end of the test period and at the last follow-up (P<0.05). However, no statistically significant differences were found in maximum cystometric capacity, maximum detrusor pressure during filling, and bladder compliance between the end of the test period and the last follow-up (P>0.05). Among the 49 patients,21 had DO and 20 had VUR. Both DO and VUR showed improvement after the test period and at the last follow-up. Conclusion SNM can effectively improve storage function in NB patients, ameliorate detrusor overactivity and bladder compliance, and relieve or eliminate VUR in some patients. Long-term follow-up confirms that SNM provides stable therapeutic effects, demonstrating significant clinical value.

Objective:To investigate the prognosis and influencing factors of endoscopic surgery for early glottic carcinoma.Methods:In this retrospective study, we applied the Cox proportional hazards regression model and the random survival forest model to analyze the clinical characteristics of 385 patients [362 males, 23 females, age ranging from 33 to 91 years (62.0±9.6)] who visited the Sixth Medical Center of the General Hospital of the People's Liberation Army from January 2009, to December 2022 and diagnosed with early glottic carcinoma, encompassing variables such as age, gender, T stage, surgical approach, pathological typing, etc. The primary evaluation indicators were overall survival(OS) and disease-free survival rates (DFS). The follow-up duration ranged from 30 to 5,557 days (with a median follow-up time of 1,596 days).Results:After a three-year follow-up, the OS rate for the 385 patients was 95.83%, while the DSF rate was 82.98%. The Cox proportional hazards regression analysis revealed age ( HR=2.35, 95% CI: 1.75 to 3.15, P<0.001) and T staging ( HR=1.59, 95% CI: 1.13 to 2.23, P=0.019) as predominant factors affecting the OS and DFS. The random survival forest model identified poor tumor differentiation, and high expression of P53 and Ki-67 as predictors of inferior prognosis. Conclusion:Endoscopic surgery for early glottic carcinoma yields favorable short-term OS and reduces short-term recurrence rates, with T-stage emerging as a pivotal factor influencing recurrence. Tumors with poor differentiation and elevated expression of P53 may be indicative of an increased risk of recurrence.

The prevalence rate of nonalcoholic fatty liver disease(NAFLD)in postmenopausal women is significantly higher than that in premenopausal women and even exceeds that in men of the same age group,and exercise intervention remains an effective method for the prevention and treatment of NAFLD in postmenopausal women.In addition,postmenopausal women with NAFLD often have comorbidities such as sarcopenia,osteoporosis,cardiovascular diseases,and diabetes,which requires targeted exercise prescriptions and proactive intervention for potential comorbidities.Through a literature review,this article provides targeted recommendations for exercise intervention prescriptions in postmenopausal women with NAFLD and related comorbidities.

Objective:To investigate the correlation between morphological typing and monoclonality of bone marrow plasma cells,and explore the diagnostic value of plasma cell morphological typing for high-risk smoldering multiple myeloma(HR-SMM).Methods:The correlation between the morphological characteristics and the monoclonality of bone marrow plasma cells was analyzed in 84 patients with HR-SMM who treated in our hospital.The consistency of morphologically abnormal bone marrow plasma cells with serum free light chain(sFLC)ratio,next-generation sequencing(NGS)detection results,and its correlation with monoclonal plasma cells detected by flow cytometry(FCM)were further verified.The immunoglobulin types and levels of non-involved immunoglobulins in serum of the patients were detected,and the distribution of plasma cell clusters in patients with different disease was observed.Results:The mean percentage of mature plasma cells were decreased successively in the order of reactive plasmacytosis(RP)group,monoclonal gammopathy of undetermined significance(MGUS)group,smoldering multiple myeloma(SMM)group,HR-SMM group and multiple myeloma(MM)group;while the mean percentage of immature,primitive,reticular and flaming plasma cells were increased successively in the order of RP group,MGUS group,SMM group,and HR-SMM group,and the difference between any two groups was statistically significant(P＜0.05).The average proportion of abnormal plasma cells in the bone marrow of HR-SMM patients was 96.2％of the total plasma cells.The proportion of abnormal plasma cells were in good agreement with the sFLC ratio and the results of NGS detection in HR-SMM patients(kappa=0.879 and kappa=0.891,both＞0.75),and showed good correlation with the monoclonal plasma cells with immunophenotype of CD45-/CD38+/CD138+/CD56+/CD19-(γ=0.825).The levels of non-involved immunoglobulin in IgG,IgA and IgM type HR-SMM patients were all decreased by more than 25％compared with the normal reference range,and the differences were statistically significant(P＜0.05).There was no significant difference in the distribution ratio of plasma cell clusters among different disease groups(P＞0.05).Conclusion:In HR-SMM patients,the immature,primitive,reticular and flaming plasma cells in bone marrow are considered as abnormal plasma cells,and they are correlated with monoclonal plasma cells.The proportion of abnormal plasma cells in total plasma cells of bone marrow and the reduction extent of non-involved immunoglobulin level in patients have certain reference value for the diagnosis of HR-SMM.

Objectives: To find the prognostic factors related to early triple-negative breast cancer to optimize the therapeutic strategies, and explore the influence of programmed cell death ligand-1(PD-L1)expression in early triple-negative breast cancer on its prognosis, so as to provide support for clinical treatment decisions. Methods: Early triple-negative breast cancer patients treated at the National Cancer Center, National Clinical Research Center for Cancer, Cancer Hospital, Chinese Academy of Medical Sciences during 1st June, 2009 and 31st Oct, 2015 were enrolled in this study. All the clinicopathological data of patients were collected, and the paraffin sections of the surgical specimens were stained with estrogen receptor, progesterone receptor, human epidermal growth factor receptor-2, secreted protein acidic and rich in cysteine (SPARC), androgen receptor, PD-L1 and other antibodies by the immunohistochemical method. Kaplan-Meier survival and Cox regression curves were used for survival analysis of relevant clinical and pathological results and nomogram survival prediction models were established to explore the influence of relevant factors on the prognosis. Results: A total of 205 patients with triple-negative breast cancer were enrolled. Ninety patients (43.9%) were PD-L1 positive. The median follow-up time was 63 months. Thirty-seven patients were relapsed or recurrent and 16 patients were dead. The 5-year disease-free survival (DFS) rate and overall survival (OS) rate were 86.1% (95% CI: 81.4%-90.8%) and 93.6% (95% CI: 91.0%-97.6%), respectively, in the general population. Univariate Cox regression analysis showed that PD-L1 expression and lymph node metastasis were correlated with DFS and OS (P<0.05). In multivariate analysis, PD-L1 expression was an independent influencing factor of DFS, with PD-L1 positive patients possessing a significant survival benefit in DFS (HR=0.31, 95% CI: 0.13-0.73). Lymph node metastasis was an independent influencing factor of OS, and OS was significantly shortened in patients with positive lymph node metastasis (HR=3.24, 95% CI: 1.15-9.17). PD-L1, lymph node metastasis, menopausal status, Ki-67 index and adjuvant chemotherapy regimen were included to establish the 1- and 3-year DFS and OS nomogram prediction models, resulting in C indices of 0.698 and 0.748, respectively. Conclusions: PD-L1 expression is a predictive biomarker of good prognostic factor in triple-negative breast cancer patients. DFS is significantly prolonged in PD-L1 positive patients and OS also shows a prolongation trend. The nomogram prognosis prediction models have reference values for adjuvant chemotherapy in this patient group.

BACKGROUND: Controversy exists as to the optimal treatment approach for ostial left anterior descending (LAD) or ostial left circumflex artery (LCx) lesions. Drug-coated balloons (DCB) may overcome some of the limitations of drug-eluting stents (DES). Therefore, we investigated the security and feasibility of the DCB policy in patients with ostial LAD or ostial LCx lesions, and compared it with the conventional DES-only strategy. METHODS: We retrospectively enrolled patients with de novo ostial lesions in the LAD or LCx who underwent interventional treatment. They were categorized into two groups based on their treatment approach: the DCB group and the DES group. The treatment strategies in the DCB group involved the use of either DCB-only or hybrid strategies, whereas the DES group utilized crossover or precise stenting techniques. Two-year target lesion revascularization was the primary endpoint, while the rates of major adverse cardiovascular events, cardiac death, target vessel myocardial infarction, and vessel thrombosis were the secondary endpoints. Using propensity score matching, we assembled a cohort with comparable baseline characteristics. To ensure result analysis reliability, we conducted sensitivity analyses, including interaction, and stratified analyses. RESULTS: Among the 397 eligible patients, 6.25% of patients who were planned to undergo DCB underwent DES. A total of 108 patients in each group had comparable propensity scores and were included in the analysis. Two-year target lesion revascularization occurred in 5 patients (4.90%) and 16 patients (16.33%) in the DCB group and the DES group, respectively (odds ratio = 0.264, 95% CI: 0.093-0.752, P = 0.008). Compared with the DES group, the DCB group demonstrated a lower major adverse cardiovascular events rate (7.84% vs. 19.39%, P = 0.017). However, differences with regard to cardiac death, non-periprocedural target vessel myocardial infarction, and definite or probable vessel thrombosis between the groups were non-significant. CONCLUSIONS The utilization of the DCB approach signifies an innovative and discretionary strategy for managing isolated ostial lesions in the LAD or LCx. Nevertheless, a future randomized trial investigating the feasibility and safety of DCB compared to the DES-only strategy specifically for de novo ostial lesions in the LAD or LCx is highly warranted.

Since the end of 2019,severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection has swept the world,bringing great harm to human society and significantly increasing the health burden.Due to stron-ger infectivity,faster transmission,and higher reinfection rate of the Omicron variant,it has now replaced the Delta variant as the main epidemic strain for both imported and local outbreaks in China.Chinese Diagnosis and treatment protocol for SARS-CoV-2 infection(10th trial version)emphasizes"strengthening the protection of key popula-tions,"which includes the increasing number of immunocompromised population.These people have a high inci-dence of severe diseases and a high fatality rate after infected with SARS-CoV-2,and belong to the high-risk popula-tions of severe or critical diseases.Moreover,due to underlying diseases,these people take immunosuppressants and other related drugs chronically.The interactions between anti-SARS-CoV-2 infection treatment drugs and origi-nal drugs are complicated,thus bring significant challenges to the treatment after the SARS-CoV-2 infection.Cur-rently,there is a lack of guidelines or consensus on the diagnosis and treatment of SARS-CoV-2 infection among im-munocompromised population.Therefore,the Guangzhou Institute of Respiratory Health and National Center for Respiratory Medicine organized experts from multiple disciplines(respiratory and critical care medicine,organ transplantation,rheumatology and immunology,hematology,infection,critical care medicine,etc.)in China.Af-ter multiple rounds of discussions,13 items of recommendations are made as the reference for peers based on evi-dence-based medical evidence,so as to provide a theoretical and practical reference for the diagnosis and treatment strategies of this population.

Objective To explore the risk factors for intracranial infection in patients after neurosurgery,con-struct and validate a Nomogram prediction model.Methods Data of 978 patients who underwent neurosurgery in a hospital in Nanjing from January 1,2019 to December 31,2022 were retrospectively analyzed.Independent risk fac-tors were screened through logistic univariate and multivariate analyses.Modeling variables were screened through Lasso regression.A Nomogram model was constructed and internally validated by logistic regression.Effectiveness of the model was evaluated with receiver operating characteristic(ROC)curve,calibration curve and decision curve.Results Among 978 patients underwent neurosurgery,293 had postoperative intracranial infection,with an inci-dence of healthcare-associated infection of 29.96％.There was no significant difference in age,gender,proportion of coronary heart disease,cerebral infarction,diabetes and hypertension between the infected group and the non-in-fected group(all P＞0.05).Multivariate logistic analysis showed that postoperative intracranial hypertension,fe-ver,increased neutrophil percentage in blood routine examination,turbid cerebrospinal fluid,positive Pan's test,decreased glucose concentration,abnormal ratio of cerebrospinal fluid/serum glucose,positive microbial culture,absence of indwelling external ventricular drainage tubes,presence of indwelling lumbar cistern drainage tubes,use of immunosuppressive agents,and long duration of surgery were independent risk factors for postoperative intracra-nial infection in patients who underwent neurosurgery(all P＜0.05).Fifteen variables were screened out through Lasso regression.Fourteen variables were finally included for modeling after collinear screening,missing data impu-tation(random forest method)and checking pairwise interaction items.A Nomogram prediction model was con-structed,with the area under ROC curve,sensitivity,specificity,and accuracy of 0.885,0.578,0.896,and 0.704,respectively.Internal validation of the model was conducted.The modeling and validation groups presented similar effects.The calibration curve and decision curve also indicated that the model had good predictive efficacy.Conclusion The constructed Nomogram prediction model for postoperative intracranial infection after neurosurgery is scientific,and the prediction indicators are easy to obtain.The model presents with high stability,reliability,and application value,thus can provide reference for the assessment of postoperative intracranial infection after neuro-surgery.

OBJECTIVE To study the intervention effect and mechanism of Zhongfeng yure decoction on ischemic stroke model rats. METHODS Totally 85 rats were randomly divided into sham operation group （normal saline， n＝15）， model control group （normal saline， n＝18）， Nimodipine tablet group （positive control， 10.8 mg/kg， n＝18）， high-dose group of Zhongfeng yure decoction （20.52 g/kg， n＝17） and low-dose group of Zhongfeng yure decoction （5.13 g/kg， n＝17）， respectively. After 7 days of preventive continuous administration （once a day）， except for the sham operation group， the rats’ middle cerebral artery occlusion （MCAO） model was established by the modified suture method in other groups. After modeling， the rats in each group continued to be administered for 3 days. During experiment， general condition of the rats was observed， and the neurological function score was performed. After the last administration， the organ index was calculated， the cerebral infarction area and pathological changes of brain tissue were observed. The levels of tumor necrosis factor-α （TNF-α） and interleukin 6 （IL-6） in brain tissue and serum， and the average optical density value of caspase-3 and phosphorylated protein kinase B（p-AKT） protein in brain tissue were detected. RESULTS Three days after modeling， compared with sham operation group， the neurological function score， in brain tissue index， spleen tissue index， proportion of cerebral infarction area， the levels of TNF-α and IL-6 in brain tissue and serum， and the average optical density value of caspase-3 protein in brain tissue were significantly increased in the model control group （P＜0.05 or P＜0.01）； karyopyknosis， diffuse edema and other lesions appeared in brain tissue. Compared with the model control group， the above indexes in each administration group were improved to varying degrees. Among them， there were significant regression in brain tissue index， spleen tissue index， proportion of cerebral infarction area， TNF-α level in brain tissue and serum， and the average optical density values of caspase-3 protein and p-AKT protein in brain tissue of rats in high-dose group of Zhongfeng yure decoction （P＜0.05 or P＜0.01）. CONCLUSIONS Zhongfeng yure decoction has a certain intervention and therapeutic effect on MCAO model rats. The mechanism may be to reduce the secretion of inflammatory factors TNF-α and IL-6， down-regulate the expression of caspase-3 protein in ischemic brain tissue， up-regulate the expression of p-AKT protein， so as to protect the neurons.
