ObjectiveTo analyze the development trajectory， research hotspots， and trends in medical humanities research in China since the new era. MethodsA search was conducted on the CNKI （China National Knowledge Infrastructure） advanced search page using the themes“medical humanities”or “humanistic medicine，”retrieving a total of 5，758 articles. After applying specific screening criteria， 5，095 articles were included in the analysis. Citespace6.1.R6 was used to visualize and analyze the authors， institutions， and keywords of the 5，095 articles. ResultsSince the new era， the volume of publications on medical humanities in China has shown an overall upward trend， with limited collaboration between core institutions and core authors. The research content of medical humanities has evolved from broad to specific， from abstract to concrete， and from theoretical to practical. ConclusionThe development of medical humanities research in China has generally gone through three stages： defining related concepts， integrating medical humanistic spirit into clinical practice， and applying empirical methods. Narrative medicine， ideological and political education in curricula， and medical humanities education are potential future research directions.

ObjectiveTo investigate the mechanisms through which Shugan Bushen Yulin decoction ameliorates spermatogenic dysfunction and sperm quality degradation caused by propylthiouracil （PTU） via the endoplasmic reticulum stress pathway in rats. MethodsSixty male rats were randomly assigned into six groups： a control group， a model group， low- （6.75 g·kg^-1）， medium- （13.5 g·kg^-1）， and high-dose （27 g·kg^-1） Shugan Bushen Yulin decoction groups， and an L-carnitine （0.27 g·kg^-1） group， with ten rats in each group. Other groups except the control group were administrated with PTU （10 mg·kg^-1） by gavage for 12 consecutive days. After the completion of modeling， rats were administrated with corresponding agents or normal saline （control group） via gavage for 28 consecutive days. Twenty-four hours after the last administration， rats were sacrificed， and the body and organ （testis， epididymis， and seminal vesicle） weights were measured to calculate the organ indices. Hematoxylin-eosin staining was employed to observe the pathological changes in the testes and epididymis， and the testicular spermatogenic function of rats was scored. Enzyme-linked immunosorbent assay was employed to measure the levels of thyroid-stimulating hormone （TSH）， triiodothyronine （T3）， thyroxine （T4）， follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， testosterone （T）， estradiol （E₂）， and malondialdehyde （MDA） and the activities of superoxide dismutase （SOD） and glutathione peroxidase （GSH-Px） in the rat serum. Terminal deoxynucleotidyl transferase dUTP nick end labeling was adopted to assess the rate of testicular cell apoptosis. Western blot was conducted to determine the expression levels of glucose-regulated protein 78 （GRP78）， CCAAT/enhancer-binding protein homologous protein （CHOP）， phosphorylated protein kinase RNA-like endoplasmic reticulum kinase （p-PERK）， protein kinase RNA-like endoplasmic reticulum kinase （PERK）， phosphorylated eukaryotic translation initiation factor 2α kinase （p-EIF2α）， eukaryotic translation initiation factor 2α kinase （EIF2α）， and activating transcription factor 4 （ATF4） in the testicular tissue of rats. ResultsCompared with the control group， the model group exhibited reductions in volumes and indexes of testes， epididymides， and seminal vesicles （P<0.01）， pathological damage of testes and epididymides， and declines in spermatogenic function and sperm density and motility （P<0.01）. In addition， the model group demonstrated elevated serum levels of TSH and MDA， lowered levels of T3， T4， FSH， LH， T， and E₂， decreased activities of SOD and GSH-Px （P<0.05， P<0.01）， an increased apoptosis rate of testicular cells （P<0.01）， and up-regulated expression of GRP78， CHOP， p-PERK/PERK， p-EIF2α/EIF2α， and ATF4 in the testicular tissue （P<0.01）. Compared with the model group， Shugan Bushen Yulin decoction at different doses improved the morphology and indexes of testes， epididymides， and seminal vesicles （P<0.05）， restored the spermatogenic function （P<0.05， P<0.01）， increased the sperm density and motility （P<0.05， P<0.01）， and decreased the percentage of apoptotic testicular cells （P<0.05）. Furthermore， the decoction lowered the serum level of MDA， elevated the serum levels of FSH， LH， T， and E₂， and increased the activities of SOD and GSH-Px （P<0.05， P<0.01）. Moreover， the expression levels of GRP78， CHOP， p-PERK/PERK， p-EIF2α/EIF2α， and ATF4 in the testicular tissue were down-regulated （P<0.05， P<0.01）. ConclusionShugan Bushen Yulin decoction can ameliorate the spermatogenic dysfunction and sperm quality degradation induced by PTU in a rat model of hypothyroidism by repairing the testicular oxidative damage and regulating the PERK/EIF2α/ATF4 signaling pathway， thereby alleviating spermatogenic cell apoptosis.

Objective To explore the diagnostic value of endoscopic grading of gastric intestinal metaplasia (EGGIM) score under acetic acid-enhanced narrow band imaging (AA-NBI) observation mode for gastric intestinal metaplasia (GIM). Methods A total of 120 patients who underwent gastroscopy at Jinshan Hospital of Fudan University from February 2022 to February 2023 were selected. All patients underwent both white light and AA-NBI endoscopy, with photographic records of intestinal metaplasia in five areas: greater curvature of antrum, lesser curvature of antrum, greater curvature of corpus, lesser curvature of corpus and incisura. EGGIM score was performed: 0 for no intestinal metaplasia, 1 point for focal intestinal metaplasia (GIM area ratio≤30%), 2 points for extensive intestinal metaplasia (GIM area ratio＞30%), with a total score of 10 points. Targeted biopsies were performed on suspicious GIM lesions found during endoscopy. If no suspicious GIM lesions were observed, random biopsies were performed according to the updated Sydney system. The pathological histological examination results were staged based on the operative link on gastric intestinal metaplasia assessment (OLGIM) system. The diagnostic value of EGGIM score for OLGIM stage Ⅲ-Ⅳ patients was evaluated using receiver operating characteristic (ROC) curves. Results The sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) of AA-NBI in detecting GIM were 96.3%, 91.6%, 94.5%, 95.0%, and 93.6%, respectively. The area under the ROC curve for EGGIM diagnosing OLGIM stage Ⅲ-Ⅳ was 0.952 (95%CI 0.914-0.990). The optimal cut-off value for EGGIM was 5 points, with a sensitivity of 96.7% (95%CI 87.6%-99.4%) and specificity of 88.1% (95%CI 76.5%-94.7%). Conclusions EGGIM score (≥5 points) under AA-NBI mode has good diagnostic capability for patients with OLGIM stage Ⅲ-Ⅳ.

Objective: To examine the reciprocal relationships of anxiety and depressive symptoms,uncertainty stress with academic buoyancy among college students, providing evidence for mental health promotion and academic resilience enhancement. Methods: A multi stage cluster random sampling method was used to selected 741 undergraduates from grade 1 to 2 of a university in Xuzhou, Jiangsu Province. Participants completed two waves of surveys (T1: October 2022; T2: October 2023) using the Uncertainty Stress Scale, Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), and Academic Buoyancy Scale. Cross lagged models analyzed bidirectional relationships between three mental health variables and academic buoyancy, followed by latent variable modeling integrating all mental health dimensions. Results: Cross lagged model results revealed that T1 uncertainty stress negatively predicted T2 academic buoyancy ( β =-0.14), while T1 academic buoyancy negatively predicted T2 uncertainty stress ( β =-0.11); T1 depressive symptom negatively predicted T2 academic buoyancy ( β =-0.08), while T1 academic buoyancy negatively predicted T2 depressive symptom ( β =-0.09); furthermore, T1 academic buoyancy negatively predicted T2 anxiety symptom( β =-0.10) ( P <0.05). Results from the latent variable cross lagged model of psychological problems (constructed from the three mental health variables) indicated that T1 psychological problems negatively predicted T2 academic buoyancy ( β =-0.09), while T1 academic buoyancy negatively predicted T2 psychological problems ( β =-0.09) ( P <0.05). Conclusions Longitudinal bidirectional relationships exist between mental health status and academic buoyancy in college students. Better mental health facilitates higher academic buoyancy.

Renal tumor scoring systems can describe the anatomical characteristics of renal tumors. It is an important standard to evaluate the surgical complexity and to evaluate the surgical complexity and feasibility of partial nephrectomy. Scholars at home and abroad have established various scoring systems based on different anatomical parameters，such as R.E.N.A.L.，PADUA，C-Index，which are used to guide the clinical selection of surgical modalities，and predict perioperative complications and prognosis. In this paper，various scoring systems are grouped into three major categories according to their functions：prediction of surgical complexity，prediction of complications，and prediction of prognosis. The contents，characteristics and clinical application value of various renal tumor scoring systems are introduced in detail to guide urologists，enhance their surgical decision-making ability，and improve the clinical outcomes.

Biliary tract cancers (BTC), a heterogeneous disease with poor prognosis, including gallbladder cancer (GBC), intrahepatic cholangiocarcinoma (ICC), and extrahepatic cholangiocarcinoma (ECC). Although surgery is currently the primary regimen to treat BTC, most BTC patients are diagnosed at an advanced stage and miss the opportunity of surgical eradication. As a result, non-surgical therapy serves as the main intervention for advanced BTC. In recent years, immunotherapy has emerged as one of the most promising therapies in a number of solid cancers, and it includes immune checkpoint inhibitors (ICIs) monotherapy or combined therapy, tumor vaccines, oncolytic virus immunotherapy, adoptive cell therapy (ACT), and cytokine therapy. However, these therapies have been practiced in limited clinical settings in patients with BTC. In this review, we focus on the discussion of latest advances of immunotherapy in BTC and update the progress of multiple current clinical trials with different immunotherapies.

Objective:To explore the causal relationship between thyroid dysfunction and sepsis based on the bidirectional two-sample Mendelian randomization (MR) method.Methods:The genome-wide association study (GWAS) dataset were selected to screen single nucleotide polymorphisms (SNP) associated with thyroid dysfunction as instrumental variable (IV) for genetic variation, using hypothyroidism and hyperthyroidism as exposure factor and sepsis as outcome factor. Potential causal relationship between thyroid dysfunction and sepsis was analyzed using a bidirectional two-sample MR method primary analysis method of inverse-variance weighted (IVW). Potential pleiotropic analysis of SNP was performed using the MR Egger regression intercept test. Sensitivity analysis was performed using the "leave one out" test. Reverse MR method was used to prove the causal relationship.Results:The GWAS data were screened based on the three main assumptions of MR, resulting in 101 SNP strongly associated with hypothyroidism and 10 SNP strongly associated with hyperthyroidism entering the MR analysis. The results of the MR using the IVW method showed that the risk of sepsis in individuals with hypothyroidism was 2.293 times higher than those without hypothyroidism [odds ratio ( OR) = 2.293, 95% confidence interval (95% CI) was 1.199-4.382, P = 0.012]. There was no significant difference in the risk of sepsis between hyperthyroid and non-hyperthyroid populations ( OR = 1.049, 95% CI was 0.999-1.100, P = 0.560). MR Egger regression intercept test showed that the included SNP did not have pleiotropy, and the MR-PRESSO test did not find outliers. Sensitivity analysis suggested that the results of MR were stable. The results of the reverse MR analysis showed that the reverse causal relationship between hyperthyroidism and sepsis was not proved ( OR = 0.996, 95% CI was 0.988-1.004, P = 0.338), which further confirmed the robust MR analysis result. Conclusion:The results of the bidirectional two-sample MR analysis show that hypothyroidism can increase the risk of sepsis onset, while there is no causal relationship between hyperthyroidism and sepsis.

Objective:To assess the prognostic impact of frailty on elderly inpatients with heart failure.Methods:This prospective cohort study enrolled 121 in elderly patients with heart failure from Beijing Hospital, the General Hospital of the People's Liberation Army, and Beijing Tsinghua Changgung Hospital between September 2018 and April 2019.Patients were assessed for frailty using the Fried frailty phenotype and categorized into frail and non-frail groups.Follow-ups were conducted at 3-, 6-, and 12-months post-enrollment through clinic visits or phone calls to record adverse events.Composite endpoints include all-cause mortality and rehospitalization duo to deterioration of heart failure.Results:The study included 121 patients with an average age of 78.0±7.4 years, of whom 71(58.7%)were male and 57(47.1%)were classified as frail.Compared to the non-frail group, the frail group had lower estimated glomerular filtration rates[49.5±20.7 ml/(min·1.73m 2) vs.(64.0±27.1)ml/(min·1.73m 2)], lower scores in Basic Activities of Daily Living[5.0(4.0, 6.0) vs.6.0(5.0, 6.0)], Instrumental Activities of Daily Living[2.0(1.3, 7.8) vs.7.0(5.0, 8.0)], and Mini-Mental State Examination[26.0(16.0, 28.0) vs.27.0(22.3, 29.0)], all P<0.05.They also experienced longer hospital stays[10.5(6.0, 18.8)days vs.8.0(6.0, 11.8)days, P=0.008].During the follow-up period, the incidence of composite endpoint events was significantly higher in the frail group(43.9% vs.25.0%, P=0.029).Kaplan-Meier survival analysis demonstrated that the one-year incidence of composite endpoint events was significantly higher in the frail group( P=0.013).Multivariable Cox regression analysisindicated that frailty was an independent risk factor for composite endpoint events( HR=2.201, 95% CI: 1.089-4.447, P=0.028). Conclusions:Frailty is an independent risk factor for poor outcomes in elderly hospitalized patients with heart failure and should be considered a crucial factor in clinical assessment and treatment strategies.

Objective:To examine the structural network changes in participants with amnestic mild cognitive impairment(aMCI)and investigate the correlation between these changes and the onset of Alzheimer's disease(AD).Methods:In this prospective study, a total of 100 individuals with amnestic mild cognitive impairment(aMCI)were enrolled as the research group.Additionally, 25 healthy individuals who were matched in terms of age and sex were enrolled as healthy controls.Upon enrollment, all participants underwent MRI scans, neuropsychological assessments, and clinical evaluations.The participants were then followed every 6 months for a period of 36 months or until they withdrew from the study.Based on the outcome of the follow-up(whether Alzheimer's disease occurred), the aMCI participants were divided into two groups: stable aMCI group and progressive aMCI group.The Chinese version of the Brief Mental State Examination(MMSE), the Montreal Cognitive Assessment(MoCA), the Clinical Dementia Rating Scale(CDR), and the Auditory Word Learning Test(AVLT)were utilized to evaluate the overall mental and cognitive status of the subjects.Pearson correlation analysis was employed to investigate the relationship between structural network changes and cognitive decline.Logistic regression was performed to analyze the predictive ability of structural network changes in determining the onset of AD.Results:Compared to the stable aMCI group, the progressive aMCI group exhibited lower levels of global efficiency( P=0.002), local efficiency( P=0.007), feeder connections( P=0.003), local connections( P=0.008), and right precuneus nodal efficiency( P=0.010).Correlation analysis revealed that global efficiency( r=0.604, P=0.002), feeder connections( r=0.513, P=0.012), and right precuneus nodal efficiency( r=0.504, P=0.014)were correlated with AVLT-delay scores(baseline)in the progressive aMCI group.A logistic regression model demonstrated that global efficiency, feeder connections, and right precuneus nodal efficiency could significantly predict the onset of AD(all P<0.05, AUCunited=0.797, 95% CI: 0.684-0.884, sensitivity=73.91, 95% CI: 51.6-89.8, specificity=76.60, 95% CI: 62.0-87.7). Conclusions:Among participants with aMCI, individuals who exhibit lower global efficiency, feeder connections, or right precuneus nodal efficiency are at a higher risk of developing AD.These indicators are anticipated to serve as new targets for clinical intervention.

The pursuit of cosmetic effects in post-surgical wounds has led to the development of ultra-minimally invasive techniques in surgery. Minimal invasive surgery has replaced open surgery and has become the new gold-standard for treating diseases. One such technique is the single incision triangulated umbilicus surgery (SITUS), which offers several advantages over traditional laparoscopic and other scarless surgeries, including reduced trauma, faster recovery, and better cosmetic outcomes. SITUS also has a short learning curve, aligns with conventional instrumentation operating habits, and can be used for whole abdominal surgeries. Chinese scholars have made further improvements to the SITUS technology, including expanding its applicability in intra-abdominal surgery and refining its incision closure methods to achieve superior cosmetic results. Currently, SITUS technology is experiencing rapid development in urology applications and has demonstrated satisfactory results in both domestic and international reports. This review aims to discuss the effectiveness and development of the SITUS technique in urology.
