Objective To explore factors associated with early postoperative hormonal remission in patients with prolactinoma and to develop prediction models based on clinical and radiological features. Methods Data from 107 patients with prolactinoma who underwent transsphenoidal surgery at The First People’s Hospital of Huai’an, Nanjing Medical University between January 2020 and December 2024 was collected, included general clinical characteristics, preoperative laboratory indicators, and imaging features. Based on whether early postoperative prolactin (PRL) levels normalized, patients were divided into a remission group (n=76) and a non-remission group (n=31). Univariate logistic regression was used for preliminary evaluation of candidate variables, followed by LASSO regression for feature selection. Multiple machine learning models were constructed, including logistic regression, random forest, support vector machine, K-nearest neighbors, naive Bayes, decision tree, neural network, and gradient boosting decision tree (GBDT). All models were trained and evaluated using ten-fold cross-validation, with comprehensive assessment of model performance based on the area under the ROC curve (AUC), accuracy, sensitivity, specificity, precision, and F1 score. Results The maximum diameter of tumors in the non remission group was larger than that in the remission group (P=0.019), and the incidence of tumor stroke and preoperative PRL levels were significantly higher than those in the remission group (P＜0.001). Univariate analysis showed that sex, maximum tumor diameter, tumor stroke, and preoperative PRL levels were influencing factors for early postoperative hormone response in patients with prolactinoma (P＜0.05). The comparison results of machine learning models show that the neural network model performs the best (AUC=0.921) and has good clinical application value, followed by the GBDT model (AUC=0.893) and the support vector machine model (AUC=0.884). Other models also show certain predictive ability. Conclusions Sex, preoperative PRL levels, maximum tumor diameter, Hounsfield unit value, and tumor stroke are important factors affecting early hormone response after prolactinoma surgery. The machine learning model constructed based on the above variables has good predictive performance, and performs the best and has good clinical application value.

Objective To investigate the current status of sleep disorders in patients with Alzheimer’s disease (AD) and its relationship with physical activity, and analyze the intervention effect of light therapy. Methods A total of 345 patients with AD admitted to the First Affiliated Hospital of Air Force Medical University from June 2020 to June 2025 were included. The Pittsburgh Sleep Quality Index (PSQI) was used to evaluate the sleep disorders, and the Physical Activity Scale for the Elderly (PASE) was applied to evaluate the physical activity. Pearson correlation analysis model was adopted to analyze the correlation between PSQI and PASE in patients with AD. 345 patients with AD were treated with light therapy intervention for 4 weeks. The changes of PSQI and PASE scores were compared before and after intervention. Results Among the 345 patients with AD, 251 cases had sleep disorders, accounting for 72.75% (251/345), and the PSQI score was (9.87±2.95) points. The scores of leisure activity, housework and occupation-related activity of PASE were (25.81±6.12) points, (78.15±12.93) points, and (45.31±8.74) points, respectively. Pearson correlation analysis model revealed that the leisure activity score of PASE was negatively correlated with the PSQI score (P<0.05), and the scores of housework and occupation-related activity were not significantly correlated with the PSQI score (P>0.05). After 4 weeks of light therapy intervention, the score of leisure activity of patients was increased significantly (P<0.05), while the scores of housework and occupation-related activity did not change significantly (P>0.05), and the PSQI scores were decreased significantly (P<0.05). Conclusion There is a correlation between sleep disorders and leisure time and physical activity in patients with Alzheimer's disease. The implementation of light therapy intervention can effectively improve sleep disorders in AD patients.

OBJECTIVE To investigate the clinical efficacy of integrating pharmacists into family health teams （FHTs） for long-term medication therapeutical management （MTM） in stroke patients， and empirically evaluate the service model. METHODS A pharmacist team， jointly established by clinical and community pharmacists from the Affiliated Suzhou Hospital of Nanjing Medical University （hereinafter referred to as “our hospital”）， developed a pharmacist-supported MTM model integrated into FHTs. Using a prospective randomized controlled design， 170 stroke patients discharged from our hospital （July 2022-December 2023） and enrolled in FHTs at Suzhou Runda Community Hospital were randomly divided into trial group （88 cases） and control group （82 cases） according to random number table. The control group received routine FHTs care （without pharmacist involvement in the team collaboration）， while the trial group xhz8405@126.com received 12-month MTM services supported by pharmacists via an information platform. These services specifically included innovative interventions such as personalized medication regimen optimization based on the MTM framework， dynamic medication adherence management， medication safety monitoring， a home medication assessment system， and distinctive service offerings. Outcomes of the 2 grousp were compared before and after intervention， involving medication adherence （adherence rate， adherence score）， compliance rates for stroke recurrence risk factors [blood pressure， low-density lipoprotein cholesterol （LDL-C）]， and incidence of adverse drug reactions （ADR）. RESULTS After 12 months， the trial group exhibited significantly higher medication adherence rates， improved adherence scores， higher compliance rates for blood pressure and LDL-C targets compared to the control group （P＜0.05）. The incidence of ADR in the trial group （4.55%） was significantly lower than that in the control group （8.11%）， though the difference was not statistically significant （P＞ 0.05）. CONCLUSIONS Pharmacist involvement in FHTs to deliver MTM services significantly enhances medication adherence and optimizes risk factor for stroke recurrence， offering practical evidence for advancing pharmaceutical care in chronic disease management under the family doctor system.

Pulmonary sarcoidosis is an immune system disease with an unclear etiology. Guided by the yang-reinforcing method， it is believed that the fundamental pathogenesis of pulmonary sarcoidosis lies in the disharmony between water and fire and the reckless movement of the ministerial fire. The failure of the spleen and stomach to maintain warmth， leading to the production of phlegm and blood stasis， is an important pathogenesis. The invasion of external pathogenic toxins， deeply penetrating into the interior， is considered a triggering factor for the disease. The treatment focuses on supplementing the yang， consolidating the kidney， drawing fire back to its source， warming the yang， benefiting the kidney， and nourishing the spleen to generate metal. It also emphasizes unblocking the yang， transforming turbidity， and eliminating phlegm and blood stasis.

Objective To analyze the characteristics of acupoint selection in treatment for func-tional constipation.Methods Clinical literature on acupuncture and electroacupuncture therapy for functional constipation from January 1,2013,to December 31,2023,was retrieved from CNKI.The acupuncture prescriptions were collected and organized,and data mining techniques were employed to analyze the patterns of acupoint selection.Results A total of 182 articles were included,yielding 123 acupuncture prescriptions involving 92 acupoints with usage frequency of 967 times.The top 10 acu-points in frequency were Tianshu(158 times),Shangjuxu(138 times),Dachangshu(61 times),Zu-sanli(60 times),Zhigou(57 times),Fujie(57 times),Guanyuan(35 times),Zhongwan(34 times),Qihai(34 times),and Quchi(28 times).The meridians of the selected acupoints for acu-puncture treatment of functional constipation were mainly involved in stomach,bladder,Ren,and spleen meridians.Association rule analysis revealed that the combination of Tianshu-Shangjuxu had the highest occurrence probability(75.82％),followed by Tianshu-Dachangshu(33.52％)and Tianshu-Zusanli(32.97％).Cluster analysis of acupoints showed that the main acupoints selected for acu-puncture treatment of functional constipation could be divided into 10 clusters,including primary acu-points,acupoints for various syndrome types,acupoints for regulating spirit,and acupoints for regula-ting sympathetic nerves.Conclusion Acupuncture treatment for functional constipation should follow the principles of holistic treatment and syndrome differentiation,combined with the methods of selecting acupoints based on their upper-lower,proximal-distal,and anterior-posterior relationships.The acu-point selection patterns identified in this study can provide important references for clinical treatment of functional constipation,offer guidance for practitioners in acupoint selection,facilitate precise treatment,and promote early patient recovery.

Objective:To assess the current status of geriatrics department development in public general hospitals at or above the second grade in Shandong province.Methods:A cross-sectional survey was conducted from October 27 to November 3, 2023 using a web-based electronic questionnaire to investigate the current status of geriatrics department development in all public general hospitals at or above the second grade across 16 prefecture-level cities in Shandong province.The survey included participation from medical department staff and managers of geriatric medicine departments.Results:Shandong province has 355 public general hospitals at or above the second grade, of which 337 completed the questionnaire.Among these 337 hospitals, 92.28%(311/337)have established geriatric departments, 83.09%(280/337)have set up geriatric clinics, 69.14%(233/337)have independent geriatric wards, and 71.51%(241/337)have implemented comprehensive geriatric assessments(CGA).Regarding the configuration of geriatric departments, 60.24%(203/337)of hospitals met the requirement of having at least 20 ward beds, 34.42%(116/337)met the doctor-to-bed ratio requirement of at least 0.3, and 22.26%(75/337)met the nurse-to-bed ratio requirement of at least 0.6.Only 13 hospitals met all the requirements for geriatric wards, beds, doctors, and nurses, accounting for 3.86%(13/337)of the participating hospitals.Conclusions:The establishment of geriatrics departments in second-grade or higher public general hospitals in Shandong province has surpassed the national target in China ahead of schedule.Most hospitals have established geriatric clinics and wards and have implemented CGA.However, significant challenges remain, including a shortage of ward beds and a lack of medical staff.

Objective:To investigate the clinicopathological characteristics, molecular features, differential diagnosis and prognosis of renal cell carcinoma (RCC) with TFEB gene amplification.Methods:A total of 113 cases of unclassified RCCs and RCCs with TFEB positive expression were collected from the Affiliated Hospital of Qingdao University and Navy 971 Hospital from January 2010 to December 2024. Eight cases of RCCs with TFEB amplification were identified using tissue microarrays, immunohistochemistry, and fluorescence in situ hybridization (FISH) techniques. The clinicopathological data and prognosis of the 8 cases were summarized, and relevant literature was reviewed.Results:Among the 8 cases, there were 5 males and 3 females. The average age was 63.4 (54, 77) year and the median age was 63.5 (59.0, 65.5) year. Seven cases were detected through physical examination, and 1 case presented with initial symptoms of metastasis to bones and lungs. The cohort included 1 biopsy specimen and 7 surgical resection specimens. The tumor diameters ranged from 2.5 to 15.0 cm. The cut surfaces of 5 cases were grayish-yellow or grayish-red, and 2 cases exhibited a colorful appearance, among which 3 cases involved renal sinus and 1 case showed invasion of the perirenal fat tissue. Microscopically, 4 cases were composed of clear cells arranged in solid sheets or acinar structures, along with varying numbers of eosinophilic cells. Two cases exhibited the morphology of high-grade eosinophilic RCC, and 1 case presented biphasic morphology with diffuse polygonal eosinophilic tumor cells and dense small cell components. The remaining 1 case exhibited the morphology of clear cell RCC. According to the WHO/ISUP nuclear grading system, 6 cases were Grade 3 and 2 cases were Grade 2. Multifocal necrosis was observed in 4 cases. In 4 surgical specimens, the tumor tissue invaded the renal parenchyma, with 2 cases showing nodular infiltration to surrounding tissues and 1 case with intravascular tumor thrombus. Immunohistochemical results showed varying degrees of TFEB nuclear positivity in 6 cases (6/8). Melanocytic markers such as Melan A (5/8) and HMB45 (3/8) were expressed at varying degrees. Cathepsin K (6/8), GPNMB (6/8), P504s (7/8) and CD10 (7/8) were positively expressed in most cases. FISH results revealed high-copy amplification of TFEB gene in 4 cases (partially showing clustered amplification) and low-copy amplification in 4 cases. During the follow-up period of 3 to 64 months of the 8 cases, 3 cases metastasized and 2 cases died of disease (both with high-copy TFEB gene amplification).Conclusions:RCC with TFEB gene amplification is rare and exhibits diverse morphological features. A common morphological characteristic of this type of tumor is a mixture of sheet-like clear cells and high nuclear grade eosinophilic cells. Combined immunohistochemical staining for TFEB, melanocytic markers, and GPNMB is helpful for the diagnosis of the tumor, and FISH detection of TFEB gene amplification is the most definitive method in diagnosing this tumor. RCC with TFEB gene amplification usually presents with strong aggressiveness and poor prognosis. Combining surgical resection with immunotherapy or VEGFR-targeted drugs might have therapeutic effects on the tumor.

Objective:To investigate the clinicopathological characteristics and diagnosis of high-grade succinate dehydrogenase-deficient renal cell carcinoma (SDH-RCC).Methods:Three cases of high-grade SDH-RCC diagnosed by immunohistochemical staining and/or molecular testing were collected from Affiliated Hospital of Qingdao University and 971 Hospital of Navy of Chinese People′s Liberation Army from January 2015 to December 2023. The clinicopathological characteristics and immunohistochemical features were summarized using light microscopy. Two cases were tested for gene mutations by next-generation sequencing.Results:Of the 3 cases, 2 were male and 1 was female. The ages were 49, 61, and 53 years, respectively. Gross examination revealed that all tumors were single nodules with diameters of 7.0, 4.5, and 5.2 cm, respectively, grayish white in color with irregular borders. Cases 1 and 2 exhibited solid cut sections, whereas case 3 had cystic and solid cut sections. Microscopically, all cases had high WHO/ISUP nuclear grade (3 or 4) and overt invasion. Case 1 exhibited a solid, sheet-like growth pattern with numerous scattered glandular ducts or acinar structures. Case 2 displayed a diffusely growth pattern reminiscent of sarcoma. Case 3 demonstrated intracystic papillary and nodular infiltrative growth patterns. Large clear cytoplasmic vacuoles could be observed in the focal areas of case 1 and case 3. Prominent peritumoral lymphocytes in stroma were noted in case 1. Case 1 was diagnosed with regional lymph node metastasis, and case 2 was diagnosed with renal vein thrombosis. Immunohistochemical staining revealed that SDHB and SDHA were deficiently expressed in 3 cases, while PAX8, FH, and INI-1 exhibited diffuse expression. CD10 (1/3), CA9 (1/3), and CK20 (1/3) were occasionally expressed. The Ki-67 proliferation index ranged from 10% to 50%. Two cases underwent next-generation sequencing and were both found to harbor pathogenic mutations in SDHA (case 2 had a frameshift mutation, and case 3 had a splice site mutation). All 3 cases were followed up for 11 to 112 months. Case 2 died 11 months post-operation, while case 1 and case 3 survived for 19 and 112 months, respectively, without any recurrence or metastasis.Conclusions:High-grade SDH-RCC is a rare subtype of SDH-RCC. The tumor exhibits various architectural patterns and is often misdiagnosed as other types of renal cell carcinoma. The presence of cytoplasmic vacuoles may be indicative for diagnosis. Compared to typical SDH-RCC, the high-grade subtype generally shows a larger tumor size, higher TNM stage, greater invasive potential, and poorer prognosis. For high-grade SDH-RCC, routine SDHB immunohistochemical staining may be necessary. The occurrence of high-grade SDH-RCC may be associated with mutations in SDHA.

BACKGROUND: The incidence and mortality rates of lung cancer remain on the rise, creating an urgent need for screening among high-risk populations and early prevention. This study aims to explore the association and interaction between multidimensional lifestyle, socioeconomic status, and the incidence of lung cancer, and to provide scientific evidence for screening high-risk populations and preventing lung cancer. METHODS: Healthy lifestyle score was constructed using information on smoking, alcohol consumption, exercise, diet and sleep obtained through a questionnaire survey. Socioeconomic status was evaluated based on information on education, employment, and family income, and genetic testing data were used to assess the risk of genetic variation. A proportional hazards assumption test was conducted, and the Cox proportional hazards model was applied to analyze the associations between healthy lifestyle scores, socioeconomic status, and lung cancer, as well as the interactions among various factors, after adjusting for the risk of genetic variation, age, gender, diabetes, hypertension and the living environment score. RESULTS: A total of 245,538 samples that entered the cohort from March, 2006 to October, 2010 were included and followed up until December 31, 2022. The participants were divided into the case group (n=1472) and the control group (n=244,066). The analysis results showed that after adjusting for covariates, there was still an association between the healthy lifestyle score, socioeconomic status, and the incidence of lung cancer: compared with participants with a high healthy lifestyle score, the risk of lung cancer in participants with medium and low healthy lifestyle scores was significantly increased, with hazard ratios (HR) of 2.12 (95%CI: 1.86-2.41) and 3.36 (95%CI: 2.82-3.99) respectively; compared with participants with high socioeconomic status, the risk of lung cancer in participants with medium and low socioeconomic status was significantly increased, with HR of 1.29 (95%CI: 1.13-1.48) and 1.67 (95%CI: 1.46-1.90) respectively. Moreover, there were interactions between smoking status and socioeconomic status (Pfor interaction=0.05), as well as the other four lifestyle factors (Pfor interaction=0.02). CONCLUSIONS This study identified the association between multidimensional lifestyle factors and socioeconomic status with the incidence of lung cancer, as well as interactions between smoking and socioeconomic status and four other lifestyle factors, providing a scientific basis for screening and prevention in high-risk populations for lung cancer.
