Diabetic cognitive impairment （DCI） has an insidious onset and progressive and irreversible development. There is currently no first-line treatment for DCI. Early intervention of diabetes with traditional Chinese medicine （TCM） can effectively control blood sugar and improve cognitive impairment， which has significant advantages. As a representative of bitter and cold heat-clearing medicines， Coptidis Rhizoma， known for its abilities to clear heat and dampness and remove turbidity and toxins， has been widely used in the clinical prevention and treatment of diabetes， Alzheimer's disease， vascular dementia， and other cognitive impairments. This article systematically summarized relevant literature and observed that Coptidis Rhizoma has shown good potential in the prevention and treatment of DCI with its active ingredients such as berberine and quercetin， drug pairs such as Coptidis Rhizoma-Scutellariae Radix， Coptidis Rhizoma-Acorus Tatarinowii Rhizoma， Coptidis Rhizoma-Pinelliae Rhizoma， Coptidis Rhizoma-Zingiberis Rhizoma， and prescriptions such as Gegen Qinliantang， Huanglian Jiedutang， Banxia Xiexintang， Huanglian Wendantang， Jiaotai Wan， Danggui liuhuangtang， and related Chinese patent medicines. Its mechanism may be related to regulating glucose metabolism， improving insulin resistance， improving amyloid β-protein （Aβ） deposition and tau protein phosphorylation， inhibiting neuroinflammation and oxidative stress， and regulating the "microbe-gut-brain axis". The article systematically reviewed the research progress of Coptidis Rhizoma and its prescriptions in the prevention and treatment of DCI， aiming to preliminarily explain the scientific connotation of Coptidis Rhizoma and provide a basis for its clinical application in the prevention and treatment of DCI.

Objective To evaluate the predictive ability and clinical application value of artificial intelligence (AI) systems in the benign and malignant differentiation and pathological type of pulmonary nodules, and to summarize clinical application experience. Methods A retrospective analysis was conducted on the clinical data of patients with pulmonary nodules admitted to the Department of Thoracic Surgery, Second Hospital of Lanzhou University, from February 2016 to February 2025. Firstly, pulmonary nodules were divided into benign and non-benign groups, and the discriminative abilities of AI systems and clinicians were compared. Subsequently, lung nodules reported as precursor glandular lesions (PGL), microinvasive adenocarcinoma (MIA), and invasive adenocarcinoma (IAC) in postoperative pathological results were analyzed, comparing the efficacy of AI systems and clinicians in predicting the pathological type of pulmonary nodules. Results In the analysis of benign/non-benign pulmonary nodules, clinical data from a total of 638 patients with pulmonary nodules were included, of which there were 257 males (10 patients and 1 patient of double and triple primary lesions, respectively) and 381 females (18 patients and 1 patient of double and triple primary lesions, respectively), with a median age of 55.0 (47.0, 61.0) years. Different lesions in the same patient were analyzed as independent samples. Univariate analysis of the two groups of variables showed that, except for nodule location, the differences in the remaining variables were statistically significant (P<0.05). Multivariate logistic regression analysis showed that age, nodule type (subsolid pulmonary nodule), average density, spicule sign, and vascular convergence sign were independent influencing factors for non-benign pulmonary nodules, among which age, nodule type (subsolid pulmonary nodule), spicule sign, and vascular convergence sign were positively correlated with non-benign pulmonary nodules, while average density was negatively correlated with the occurrence of non-benign pulmonary nodules. The area under the receiver operating characteristic curve (AUC) of the malignancy risk value given by the AI system in predicting non-benign pulmonary nodules was 0.811, slightly lower than the 0.898 predicted by clinicians. In the PGL/MIA/IAC analysis, clinical data from a total of 411 patients with pulmonary nodules were included, of which there were 149 males (8 patients of double primary lesions) and 262 females (17 patients of double primary lesions), with a median age of 56.0 (50.0, 61.0) years. Different lesions in the same patient were analyzed as independent samples. Univariate analysis results showed that, except for gender, nodule location, and vascular convergence sign, the differences in the remaining variables among the three groups of PGL, MIA, and IAC patients were statistically significant (P<0.05). Multinomial multivariate logistic regression analysis showed that the differences between the parameters in the PGL group and the MIA group were not statistically significant (P>0.05), and the maximum diameter and average density of the nodules were statistically different between the PGL and IAC groups (P<0.05), and were positively correlated with the occurrence of IAC as independent risk factors. The average AUC value, accuracy, recall rate, and F1 score of the AI system in predicting lung nodule pathological type were 0.807, 74.3%, 73.2%, and 68.5%, respectively, all better than the clinical physicians’ prediction of lung nodule pathological type indicators (0.782, 70.9%, 66.2%, and 63.7% respectively). The AUC value of the AI system in predicting IAC was 0.853, and the sensitivity, specificity, and optimal cutoff value were 0.643, 0.943, and 50.0%, respectively. Conclusion This AI system has demonstrated high clinical value in predicting the benign and malignant nature and pathological type of lung nodules, especially in predicting lung nodule pathological type, its ability has surpassed that of clinical physicians. With the optimization of algorithms and the adequate integration of multimodal data, it can better assist clinical physicians in formulating individualized diagnostic and treatment plans for patients with lung nodules.

Objective To systematically evaluate the effect and safety of neoadjuvant PD-1/PD-L1 inhibitors combined with chemotherapy for resectable non-small cell lung cancer (NSCLC). Methods The PubMed, EMbase, The Cochrane Library, CNKI, and Wanfang data were searched by computer to identify relevant studies on anti PD-1 /PD-L1 combined with chemotherapy for resectable NSCLC from inception to March 2023. Two authors independently screened the literature, extracted the data, and evaluated the risk of bias in the included studies. The single-arm study was evaluated for quality using the methodological index for non-randomized studies (MINORS). Meta-analysis was conducted by RevMan 5.4 software. Results Twenty-six studies with 965 patients were included in this meta-analysis. MINORS scores of single-arm studies were ≥12 points. The meta-analysis results showed that the pooled pathologic complete response, major pathologic response, and objective response rates as well as partial response, surgical rate and R0 surgical resection rate of neoadjuvant PD-1/PD-L1 inhibitors combined with chemotherapy were 39% [RD=0.39, 95%CI (0.31, 0.47) ], 59% [RD=0.59, 95%CI (0.53, 0.65) ], 72% [RD=0.72, 95%CI (0.65, 0.80) ], 62% [RD=0.62, 95%CI (0.56, 0.69) ], 86% [RD=0.86, 95%CI (0.81, 0.92) ], and 94% [RD=0.94, 95%CI (0.92, 0.97) ], respectively. In terms of safety, the rate of adverse events (AEs) was 65% [RD=0.65, 95%CI (0.52, 0.78) ], and the rate of grade 3 to 5 AEs was 16% [RD=0.16, 95%CI (0.10, 0.23) ]. Conclusion The combination of neoadjuvant PD-1/PD-L1 inhibitors with chemotherapy has good efficacy and safety in the treatment of patients with resectable NSCLC.

BACKGROUND:Prevention of fractures after stroke is very important,and there are currently no models to predict the occurrence of hip fractures after stroke. OBJECTIVE:To investigate the risk factors leading to hip fracture in stroke patients and to establish a risk prediction model to visualize this risk. METHODS:A total of 439 stroke patients were selected from the Affiliated Hospital of Xuzhou Medical University from June 2014 to June 2017,including 107 males and 332 females,with a mean age of(71.38±9.74)years.They were divided into fracture group(n=35)and non-fracture group(n=404)according to the presence or absence of hip fracture.Univariate and multivariate analyses were used to determine the risk factors for hip fracture after stroke.The data were randomly divided into training set(70%)and test set(30%).Nomogram predicting the risk of hip fracture occurrence was created based on the results of the multifactor analysis,and performance was evaluated using receiver operating characteristic curve,calibration curves,and decision curve analysis.A web calculator was created to facilitate a more convenient interactive experience for clinicians. RESULTS AND CONCLUSION:(1)Univariate analysis showed significant differences between the two groups in the number of falls,smoking,hypertension,glucocorticoids,number of strokes,Mini-Mental State Examination,visual acuity level,National Institute of Health Stroke Scale,Berg Balance Scale,and Stop Walking When Talking scale scores(P<0.05).(2)Multivariate analysis showed that number of falls[OR=17.104,95%CI(3.727-78.489),P=0.000],National Institute of Health Stroke Scale[OR=1.565,95%CI(1.193-2.052),P=0.001],Stop Walking When Talking[OR=12.080,95%CI(2.398-60.851),P=0.003]were independent risk factors positively associated with new hip fractures.Bone mineral density[OR=0.155,95%CI(0.044-0.546),P=0.012]and Berg Balance Scale[OR=0.840,95%CI(0.739-0.954),P=0.007]were negatively associated with new hip fractures after stroke.(3)The AUC values of nomogram were 0.956 and 0.907 in the training and test sets,respectively,and the calibration curves showed a high agreement between predicted and actual status with an area under the decision curve of 0.038 and 0.030,respectively.(4)These findings conclude that the number of falls,low bone mineral density,low Berg Balance Scale score,high National Institute of Health Stroke Scale score,and positive Stop Walking When Talking are risk factors for hip fracture after stroke.Based on this,a nomogram with high accuracy was developed and a web calculator(https://stroke.shinyapps.io/DynNomapp/)was created.

Objective: To explore the treatment options for congenitally missing teeth in patients with ectodermal dysplasia and provide a clinical reference. Methods: A patient with ectodermal dysplasia with a concave midface, anterior protrusion of the chin, and underdevelopment of the lower third of the face presented with congenital loss of multiple maxillary teeth, malocclusion of the remaining teeth, congenital loss of mandibular dentition, small dental arches, and upper and lower alveolar bone hypoplasia. The patient was treated by means of a removable partial maxillary prosthesis, implants in the anterior region of the lower mandible designed with the assistance of digital guides, and bar-clamped implant-overlay prostheses. A literature review of the protocol for the treatment of this condition was also conducted. Results: In addition to good retention and stability after denture wear, an excellent occlusal relationship, improvement of the patient's facial appearance, including upper and lower lip fullness, more equal balancing of the lower and middle 1/3 of the face, and improved masticatory function were achieved. The results of the literature review showed that patients with ectodermal dysplasia who are congenitally edentulous usually have a complex intraoral situation that makes restoration difficult, and common restorative modalities for these patients include fixed bridges, removable partial dentures, complete dentures, overdentures, and implant prostheses, which need to be selected according to the actual intraoral situation of each patient. Currently, there is no consensus on the treatment of congenitally missing teeth in patients with ectodermal dysplasia, and some scholars have suggested that fixed restorations be recommended for patients with fewer missing teeth, while the option of removable or implant-covered denture restorations should be given to patients with more missing teeth, with removeable prostheses for underage patients that are replaced with permanent fixed prostheses when the jaws have stabilized. Conclusion In patients with ectodermal dysplasia with congenital tooth loss, all factors should be taken into account, and an individualized restorative plan should be developed.

Background and objective Lung cancer is the cancer with the highest incidence and mortality rates in China,and non-small cell lung cancer(NSCLC)accounts for 80％-85％of all malignant lung tumors.Currently,surgical treat-ment remains the primary treatment modality for lung cancer.In recent years,the effectiveness of immune checkpoint inhibi-tors for NSCLC has become a consensus,and neoadjuvant immunochemotherapy(nICT)has shown promising efficacy and safety in early to intermediate stage NSCLC.However,there are fewer studies related to nICT for locally advanced NSCLC.This study aims to evaluate the efficacy and safety of nICT therapy in locally advanced resectable NSCLC.Methods 85 con-firmed resectable stage ⅢA and ⅢB patients treated in the Department of Thoracic Surgery,Second Hospital of Lanzhou University,from January 2021 to April 2024,were divided into the nICT group(n=32)and the surgery alone group(n=53).Clinical baseline data,perioperative indicators,postoperative complications,imaging response rate,pathological response rate,incidence of adverse events,and quality of life were compared between the two groups.Results There were no statisti-cally significant differences in clinical baseline data between the two groups(P＞0.05).Incidence of choosing thoracotomy was higher in the nICT group than in the surgery alone group(P=0.002).There were no significant differences in surgical time,intraoperative blood loss,number of dissected lymph nodes,duration of chest tube placement,postoperative hospital stay,and R0 resection rate between the two groups(P＞0.05).The overall incidence of postoperative complications was 31.25％in the nICT group and 22.64％in the surgery alone group,with no statistically significant difference(P=0.380).In the nICT group,the objective response rate(ORR)was 84.38％,with 5 cases of complete response(CR)(15.63％),22 cases of partial response(PR)(68.75％),15 cases of pathological response rate(pCR)(46.88％),and 11 cases of major pathological reaponse(MPR)(34.38％).During nICT treatment,12 cases(37.50％)experienced grade 3 treatment-related adverse events,no death induced by adverse events or immune related adverse events.Moreover,the symptoms of the patients were improved after nICT treat-ment.Conclusion Neoadjuvant immunochemotherapy shows promising efficacy in locally advanced resectable NSCLC,with manageable treatment-related adverse events.It is a safe and feasible neoadjuvant treatment modality for locally advanced resectable NSCLC.

Objective:To investigate the surgical decision-making types and its influencing factors for obesity patients participating in bariatric metabolic surgery.Methods:The survey targets were patients who were scheduled to bariatric metabolic surgery in The First Affiliated Hospital of Nanjing Medical University, and the survey period was from January 1 to May 30, 2024. The survey was conducted using the general demographic questionnaire, control preference scale, and shared-decision requirements questionnaire for bariatric metabolic surgery. Count data were expressed as absolute numbers and percentages, and comparison between groups was performed using the chi-square test. Comparison of ordinal data was performed using the non parametric test. Univariate analysis was performed using the corresponding statistical methods based on data types. Multivariate analysis was conducted using the willingness of patients to participate in bariatric metabolic surgery decision-making (passive decision-making=1, shared decision-making=2, active decision-making=3) as the dependent variable, and the statistically significant variables in univariate analysis were included as independent variables for disordered multi-class Logistic regression analysis.Results:(1) Results of survey. A total of 568 questionnaires were distributed and collected. After removing 48 unqualified questionnaires, 520 valid questionnaires were collected. Of the 520 patients who completed the questionnaire survey, there were 231 cases participating as the passive decision-making type, 140 cases as shared decision-making type, and 149 as active decision-making type in bariatric metabolic surgery decision-making. (2) Influencing factors for decision-making type of obesity patients participating in bariatric metabolic surgery. Results of multivariate analysis showed that taking the shared decision-making type as a reference, the number of complication (0 compared to ≥4, 1?3 compared to ≥4), medical payment method (medical insurance compared to self-payment), degree of disease understanding (not very understanding compared to general understanding, not understanding compared to general understanding), and the interval between knowing and accep-ting surgery (1-3 months compared to >6 months) were independent factors influencing the willingness of passive decision-making patients to participate in bariatric metabolic surgery deci-sions ( odds ratios=3.520, 2.457, 2.255, 3.147, 1.920, 1.854, 95% confidence interval as 1.552-7.984, 1.215-4.968, 1.335-3.809, 1.865-5.311, 1.025-3.596, 1.065-3.230, P<0.05). Body mass index (BMI) (28.0-31.9 kg/cm 2 compared to ≥37.0 kg/cm 2, 32.0-36.9 kg/cm 2 compared to ≥37.0 kg/cm 2), number of complication (0 compared to ≥4, 1?3 compared to ≥4), family and social support status (poor compared to good), and the interval between knowing and accepting surgery (1?3 months compared to >6 months) were independent factors influencing the willingness of passive decision-making patients to participate in bariatric metabolic surgery decisions ( odds ratios=2.391, 2.478, 6.918, 3.335, 2.974, 2.139, 95% confidence intervals as 1.207-4.735, 1.345-4.563, 2.498-19.159, 1.350-8.242, 1.755-5.039, 1.156-3.957, P<0.05). Taking the passive decision-making type as a reference, BMI (28.0-31.9 kg/cm 2 compared to ≥37.0 kg/cm 2, 32.0-36.9 kg/cm 2 compared to ≥37.0 kg/cm 2) and family social support status (poor compared to good) were independent factors influencing the willingness of passive decision-making patients to participate in bariatric metabolic surgery decisions ( odds ratios=0.404, 0.554, 0.336, 95% confidence interval as 0.221-0.740, 0.327-0.938, 0.212-0.534, P<0.05). (3) Analysis of decision support needs for bariatric metabolic surgery. Results of shared-decision requirements questionnaire showed that the information needs of obesity patients from high to low were surgical indications, postoperative physical changes and dietary habits adjust-ments, surgical costs, surgical complications and risks, and surgical outcomes. The demand for content preference from high to low were in the form of sharing patient experience after bariatric metabolic surgery, comparing before and after bariatric metabolic surgery, popularizing science after bariatric metabolic surgery, introducing surgical methods, live streaming of medical staff, and introducing the hospital environment. In terms of recognition of networked support pathways, 94.04%(489/520) of patients believed that implementing shared decision support based on networked pathways was reliable. Conclusions:Obesity patients are more willing to participate in bariatric metabolic surgery decision-making. But the proportion of patients selecting passive decision-making is relatively high. BMI, number of complication, medical payment method, degree of disease under-standing, family and social support status and the interval between knowing and accepting surgery are independent factors influencing the willingness of obesity patients to paticipate in bariatric metabolic surgery decisions.

Male infertility (MI) and male sexual dysfunction (MSD) can often coexist together due to various interplay factors such as psychosexual, sociocultural and relationship dynamics. The presence of each form of MSD can adversely impact male reproduction and treatment strategies will need to be individualized based on patients’ factors, local expertise, and geographical socioeconomic status. The Asia Pacific Society of Sexual Medicine (APSSM) and the Asian Society of Men’s Health and Aging (ASMHA) aim to provide a consensus statement and practical set of clinical recommendations based on current evidence to guide clinicians in the management of MI and MSD within the Asia-Pacific (AP) region. A comprehensive, narrative review of the literature was performed to identify the various forms of MSD and their association with MI. MEDLINE and EMBASE databases were searched for the following English language articles under the following terms: “low libido”, “erectile dysfunction”, “ejaculatory dysfunction”, “premature ejaculation”, “retrograde ejaculation”, “delayed ejaculation”, “anejaculation”, and “orgasmic dysfunction” between January 2001 to June 2022 with emphasis on published guidelines endorsed by various organizations. This APSSM consensus committee panel evaluated and provided evidence-based recommendations on MI and clinically relevant MSD areas using a modified Delphi method by the panel and specific emphasis on locoregional socioeconomic-cultural issues relevant to the AP region. While variations exist in treatment strategies for managing MI and MSD due to geographical expertise, locoregional resources, and sociocultural factors, the panel agreed that comprehensive fertility evaluation with a multidisciplinary management approach to each MSD domain is recommended. It is important to address individual MI issues with an emphasis on improving spermatogenesis and facilitating reproductive avenues while at the same time, managing various MSD conditions with evidence-based treatments. All therapeutic options should be discussed and implemented based on the patient’s individual needs, beliefs and preferences while incorporating locoregional expertise and available resources.

Osteoarthritis is a chronic inflammatory disease characterized by non inflammatory degeneration of articular cartilage and the formation of osteophytes at the edge of the joint, caused by complex causes. Its pathology is complex, and its pathogenesis is not yet clear, ultimately leading to joint stiffness and functional activity disorders. At present, the treatment for osteoarthritis is limited to alleviating symptoms and improving function, with varying degrees of side effects. Ferroptosis is a new type of programmed cell death discovered in recent years, which is related to the pathological and physiological processes of osteoarthritis and plays an important regulatory role in the occurrence and development of osteoarthritis. Its main characteristics include iron metabolism imbalance and accumulation of reactive oxygen species. Therefore, ferroptosis inhibitors targeting ferroptosis have shown great application prospects in the treatment of osteoarthritis. In this review, the author summarizes the relevant mechanisms of ferroptosis in the occurrence and development of osteoarthritis, outlines a large number of specific therapeutic drugs and their corresponding targets, with the aim of delaying and reversing the progression of osteoarthritis by regulating chondrocyte ferroptosis, which has certain clinical guiding significance.
