Objective To propose a whole-life cycle management model for valvular heart disease (VHD), systematically elucidate its underlying logic and implementation pathways, and concurrently review and analyze its preliminary application outcomes. Methods Since 2020, West China Hospital of Sichuan University has established a management system encompassing "assessment-decision-intervention-follow-up", including: (1) a risk-stratified, tiered management pathway; (2) six core functions ("promotion, screening, prevention, diagnosis, treatment, and rehabilitation") coordinated by disease-specific managers; (3) an intelligent decision support information platform; and (4) a collaborative network of multidisciplinary teams and regional academic alliances. To evaluate the effectiveness of this management model, we retrospectively included three cohorts: (1) the population screened by echocardiography from 2020 to 2024, analyzing the detection rate of aortic valve disease and risk stratification; (2) patients enrolled in the whole-life cycle management from April 2021 to December 2024, assessing follow-up outcomes, hospital satisfaction, and changes in quality of life; (3) patients who underwent transcatheter aortic valve replacement (TAVR) from January 2022 to January 2024, evaluating the one-year all-cause mortality rate, perioperative complications, and improvements in New York Heart Association (NYHA) classification. Results Between 2020 and 2024, a total of 583 874 individuals underwent echocardiographic screening. A total of 48 089 patients with aortic valve disease were identified, including 3 401 (7.1%) high-risk patients, 18 657 (38.8%) moderate-risk patients, and 26 031 (54.1%) low-risk patients. Among them, 2 417 patients were enrolled in whole-life cycle management. Patient satisfaction scores showed a yearly increase, rising from 73.89 points before 2020 to 93.74 points in 2024. The 1-year mortality rate in the TAVR cohort decreased to 5.3%, significantly lower than the 8.2% observed under early standard management between 2014 and 2019 (P<0.01). Conclusion Through process optimization and resource integration, the VHD whole-life cycle management model has demonstrated significant effectiveness in standardizing diagnostic and follow-up procedures, enhancing patient satisfaction and quality of life, and reducing mortality. These outcomes highlight its practical value for broader implementation in China.

BACKGROUND:Pulsed electromagnetic field is a non-invasive and non-radiative treatment method.Clinical use of pulsed electromagnetic fields in the treatment of orthopedic diseases has achieved certain results. OBJECTIVE:To review the current clinical application of the pulsed electromagnetic field in the treatment of orthopedic diseases,providing a scientific theoretical basis for the clinical treatment of orthopedic diseases. METHODS:The first author used a computer to search PubMed,CBM,Cochrane Library,CNKI,and WanFang Data for related studies on the pulsed electromagnetic field in the treatment of orthopedic diseases,using the keywords of"pulsed electromagnetic field,orthopedics,osteoarthritis,osteoporosis,bone healing,electromagnetic navigation"in English and Chinese.For the literature related to the same content,recent publications were selected.A total of 69 articles were selected from the search results for review. RESULTS AND CONCLUSION:Pulsed electromagnetic field has a definite curative effect on fracture healing.It can be used in the treatment of osteomyelitis by antibacterial,bactericidal,anti-inflammatory and promoting bone healing,and can inhibit osteoporosis and its progress.In addition,the treatment of early osteoarthritis,femoral head necrosis and postoperative rehabilitation of late joint replacement through various ways can become a treatment for orthopedic diseases.However,the therapeutic mechanism of the pulsed electromagnetic field for a variety of orthopedic diseases is still unclear,and most of the research is still in the primary stage.In the future,it is still necessary to obtain more reliable evidence from high-quality research and clinical trials to provide a more perfect basis for the clinical treatment of orthopedic diseases.

Objective: To explore the intervention effect of group counseling integrating teadrinking on depression, social avoidance and distress, coping styles and selfesteem among college students, so as to provide references for promoting the psychological health of students. Methods: From March to June 2021, a convenience sampling method was used to recruit 46 college students from a university in Nanjing for intervention project. There were 23 students in intervention group and control group, respectively. The intervention was conducted for 2.5 hours per week across a 6 week period. The intervention group received two sessions of group counseling that incorporated teadrinking experience, and the sessions involved tea knowledge explanation, observation and learning, embodied experience, emotional expression, interpersonal assistance and emotional support, cultural customs and life integration. After the intervention was completed, the control group received onetime group counseling that integrated teadrinking. The Wilcoxon difference test and Mann-Whitney U test were performed to compare the scores of each scale within and between the groups, and the χ2 test was used to compare the detection rates. Results: There were no statistically significant differences in the scores of positive coping, negative coping, selfesteem, social avoidance and distress between the intervention group and the control group (Z=-1.20, -0.33, -0.35, 1.31,P>0.05). There were statistically significant differences in positive coping styles, selfesteem, social avoidance and distress between the intervention group and the control group after the intervention(27.70±5.60，22.05±4.30；30.52±3.63，28.27±4.06；7.43±7.38，13.64±6.79) (Z=-3.31, -2.10, 3.22, P<0.05). The intervention group showed statistically significant differences in social avoidance and distress scores before and after the intervention(11.96±7.47,7.43±7.38) (Z=-2.88), and the depression detection rate decreased(60.9%，30.4%) (χ2=4.29) (P<0.05). There were no statistically significant differences in positive coping, negative coping, selfesteem, social avoidance and distress scores, and depression detection rate between the control group before and after the intervention (Z/χ2=-0.28, -0.42, -1.24, -1.25；1.39, P>0.05). The followup results 1year later showed that there was a statistically significant difference in social avoidance and distress(6.57±6.21,14.16±9.22), and in the detection rates of depression(21.7%,52.2%) between the intervention group and the control group (Z/χ2=2.70,4.57,P<0.05). Conclusions Group counseling integrating teadrinking could improve interpersonal relationships, emotional states, selfesteem levels and coping strategies among college students. Group psychological counseling that incorporates teadrinking can be adopted to improve the mental health status of college students.

Objective:To analyze the status of anemia at the beginning of dialysis in maintenance hemodialysis (MHD) adult patients, and to explore the relationship between early dialysis anemia and early survival and long-term survival.Methods:It was a retrospective cohort study. The baseline demographic and clinical data of newly admitted MHD patients from January 1, 2013 to December 31, 2020 were retrospectively analyzed. According to the hemoglobin (Hb) level at the beginning of dialysis, the patients were divided into high Hb group (Hb≥110 g/L), middle Hb group (80 g/L≤Hb<110 g/L) and low Hb group (Hb<80 g/L). The baseline data among the three groups were compared, and the changing trend of Hb level in MHD patients during the 8 years was analyzed. The follow-up ended at peritoneal dialysis, kidney transplantation, death or on December 31, 2021. All-cause death event within 6 months after the initiation of dialysis was defined as early death, while all-cause death event more than 6 months after the initiation of dialysis was defined as long-term death. Kaplan-Meier survival curve was used to analyze the survival rate, and log-rank test was used to compare the survival rates among the three groups. Multivariate Cox regression analysis model was used to analyze the association between anemia (Hb<110 g/L) at the beginning of dialysis and both early and long-term mortality.Results:A total of 36 216 MHD patients were included in this study, with age of (61.3±15.5) years old and 22 163 males (61.20%). The Hb at the beginning of dialysis was (89.33±20.89) g/L. The compliance rate of Hb (≥110 g/L) was 16.43% (5 952/36 216). There were 12 232 patients (33.78%), 18 032 patients (49.79%), and 5 952 patients (16.43%) in low Hb group, middle Hb group, and high Hb group, respectively. There were statistically significant differences in gender distribution, age, serum creatinine, blood phosphorus, blood calcium, C-reactive protein, intact parathyroid hormone, blood leukocytes, platelets, serum albumin, triglyceride, total cholesterol, and proportions of chronic glomerulonephritis, diabetic nephropathy, diabetes mellitus, cardiovascular and cerebrovascular diseases, tumors, emporary catheter, long-term catheter and autologous arteriovenous fistula among the three groups (all P<0.05). During the 8-year period, the Hb level had an increased trend steadily each year, and Hb was (88.48±22.07) g/L, (88.52±21.43) g/L, (87.86±21.29) g/L, (88.93±20.69) g/L, (88.87±20.69) g/L, (90.03±20.47) g/L, (90.74±20.31) g/L and (90.31±20.54) g/L year by year. There were 2 176 early deaths (6.01%), and 6 557 long-term deaths (18.10%) by the end of follow-up. Kaplan-Meier survival curve showed that early survival rate of low Hb group was significantly lower than those of high Hb group (log-rank test, χ2=57.115, P<0.001) and middle Hb group (log-rank test, χ2=49.918, P<0.001), and long-term survival rates of low Hb group (log-rank test, χ2=107.097, P<0.001) and middle Hb group (log-rank test, χ2=47.430, P<0.001) were significantly lower than that of high Hb group. Multivariate Cox regression analysis showed that Hb<80 g/L at the beginning of dialysis was an independent influencing factor of early death (Hb ≥110 g/L as a reference, HR=1.307, 95% CI 1.096-1.559), and 80 g/L≤Hb<110 g/L and Hb<80 g/L at the beginning of dialysis were the independent influencing factors of long-term death (Hb≥110 g/L as a reference, HR=1.108, 95% CI 1.021-1.203; HR=1.228, 95% CI 1.127-1.339, respectively) in MHD patients. Conclusions:The compliance rate of Hb at the beginning of dialysis in MHD patients is low. Hb <80 g/L at the beginning of dialysis is an independent risk factor of early death, and Hb <110 g/L at the beginning of dialysis is an independent risk factor of long-term death in MHD patients.

Objective To investigate the dietary patterns of rural residents in the high-incidence areas of esophageal cancer (EC), and to explore the clustering and influencing factors of risk factors associated with high-incidence characteristics. Methods A special structured questionnaire was applied to conduct a face-to-face survey on the dietary patterns of rural residents in Yanting county of Sichuan Province from July to August 2021. Univariate and multivariate logistic regression models were used to analyze the influencing factors of risk factor clustering for EC. Results There were 838 valid questionnaires in this study. A total of 90.8% of rural residents used clean water such as tap water. In the past one year, the people who ate fruits and vegetables, soybean products, onions and garlic in high frequency accounted for 69.5%, 32.8% and 74.5%, respectively; the people who ate kimchi, pickled vegetables, sauerkraut, barbecue, hot food and mildew food in low frequency accounted for 59.2%, 79.6%, 68.2%, 90.3%, 80.9% and 90.3%, respectively. The clustering of risk factors for EC was found in 73.3% of residents, and the aggregation of two risk factors was the most common mode (28.2%), among which tumor history and preserved food was the main clustering pattern (4.6%). The logistic regression model revealed that the gender, age, marital status and occupation were independent influencing factors for the risk factors clustering of EC (P<0.05). Conclusion A majority of rural residents in high-incidence areas of EC in Yanting county have good eating habits, but the clustering of some risk factors is still at a high level. Gender, age, marital status, and occupation are influencing factors of the risk factors clustering of EC.

Objective:To analyze the safety of reduced clinical target volume (CTV) irradiation of suspicious positive lymph nodes in IIa region in patients with N 0-N 1 nasopharyngeal carcinoma (NPC) and the protective effect of submandibular gland and long-term resting dry mouth, and to explore the diagnostic value of multimodal imaging for suspicious cervical lymph nodes. Methods:Clinical data of T 0-4N 0-1M 0 stage NPC patients admitted to Jiangsu Cancer Hospital from July 2015 to April 2017 were retrospectively analyzed. Clinical, radiation therapy planning, multimodal imaging and other relevant data were collected. All patients were treated with an optimized regimen of IMRT with a prophylactic radiation dose of 50.4 Gy (named as CTV50) for IIa region. Imaging characteristics and treatment response of suspicious lymph nodes were monitored by MRI, MRI-DWI, PET-CT and repeated enhanced positioning CT, etc. The dosimetry of the submandibular gland between optimized and standard dose plans (CTV50 vs. CTV60) was compared by paired t-test. The long-term dry mouth degree of the patients was evaluated using advanced radiation injury from Radiation Therapy Oncology Group (RTOG), Jiangsu Cancer Hospital Multi-dimensional Dry Mouth Evaluation Scale and summated xerostomia inventory (SXI). The difference of dry mouth degree was analyzed by rank-sum test. Results:A total of 106 patients were included in this study, including 149 cervical lymph node negative sides, 73 sides of which had ≤3 recognizable lymph nodes, and 76 of which were>3 in Ⅱa region. Among patients with N 1 stage, 63 patients underwent contralateral single neck area optimization, and 43 patients (N 0 stage and N 1 stage patients with retropharyngeal lymph node metastasis) underwent double-neck area optimization. A total of 109 suspicious lymph nodes with a short diameter of >5 mm were found on the largest cross section, of which 105 had clear portal structure. The ratio of long to short diameter was ≥1.5 in 93 cases, and the maximum standardized uptake value (SUV max) in PET-CT was ≥2.5 in 76 cases. No lymph node recurrence was found in the CTV optimized area. There was no significant difference in the average dose of GTV in tumor target area after optimization ( P>0.05), and the D mean and V 39 Gy in submandibular gland were significantly lower than those in unoptimized plan (both P<0.01). There was no significant difference in long-term dry mouth and resting dry mouth between patients with unilateral and bilateral optimization of submandibular gland (both P>0.05). Conclusions:The optimal program of CTV50 reduction irradiation in Ⅱa area of N 0-N 1 NPC patients is safe and effective. The submandibular gland has obvious dosimetric advantages, and patients have a good subjective response to resting dry mouth. The multimodal imaging tools such as enhanced CT, MRI-DWI and PET-CT should be performed to deliver individual evaluation and treatment for suspicious lymph nodes.

IgG4-related disease (IgG4-RD) involving the ureter manifested as a ureteral tumor is rare. This paper reports a case of a female patient who was found with a mass at the left ureteropelvic junction for one week during physical examination. Urinary ultrasound and MRI showed a 3 cm mass at the left ureteropelvic junction with hydronephrosis, and the serum level of IgG4 was elevated. B-ultrasonic guided biopsy of the mass was performed. Histopathological findings showed lymphoplasmic infiltration and the ratio of IgG4/IgG positive cells>0.5. We finally diagnosed IgG4-RD and started using glucocorticoid for her treatment. One month later, CT-scan revealed that the tumor became smaller and the serum IgG4 decreased to the normal range.

Ectopic prostate is rare.This paper reports a case of a male patient who was found a mass in the pelvis for 20 days during physical examination.Urinary ultrasound, CT scan and MRI showed a pelvic mass that was about 4 cm×5 cm in size.Serum total prostate specific antigen (tPSA) was 6.09 ng/ml, and free PSA (fPSA) was 1.97 ng/ml. B-ultrasonic guided biopsy of the prostate and the mass was performed. Pathological findings suggest benign prostatic hyperplasia, weakly positive P504S and positive 34βE12. Pelvic mass is the prostate tissue with negative P504S and positive 34βE12. Finally, the ectopic prostate was diagnosed. Although it is rare, ectopic prostate should also be considered as a differential diagnosis of the pelvic tumor.

Objective:To explore effect of Glioma-associated oncogene family zinc finger 1(GLI1)on hypoxia induced trans-formation of NR8383 to M1 phenotype and development of pulmonary hypertension(PH).Methods:Fifteen adult male Wistar rats were randomly divided into control group,hypoxia PH model group and hypoxic PH with GANT61 treatment group,with 5 rats in each group.PH related indexes of rats were detected by small animal ultrasound and right cardiac catheter experiment to determine effect of GLI1 specific inhibitor GANT61 on progression of PH.Pulmonary arterial thickness was measured by HE staining.α-SMA and M1 polarization markers TNF-α and IL-1β expressions were determined by immunohistochemistry.M1 polarization markers CD86 and TNF-α expressions were determined by immunofluorescence.GLI1 expression and NF-κB protein were detected by Western blot.mRNA expressions of iNOS,CD86,TNF-α,IL-1β and IL-12 were detected by qRT-PCR.CHIP-PCR verified that GLI1 regulates NF-κB promoter activity.IL-12 content was detected by ELISA.Rat pulmonary artery smooth muscle cells proliferation was detected by CCK-8.Results:GLI1 inhibitor GANT61 could alleviate symptoms of PH in hypoxic rats(P<0.05).Compared with hypoxic group,inhibition of GLI1 reduced expressions of TNF-α and IL-1β in rat lung tissue(P<0.05).In cell experiments,hypoxia induced M1 polarization of NR8383 by up-regulating GLI1 to activate NF-κB pathway,GLI1 overexpression increased expressions of iNOS,CD86,TNF-α,IL-1β and IL-12 in M1 macrophages(P<0.05).NR8383 culture supernatants could stimulate pulmonary artery smooth muscle cell proliferation(P<0.05)and contribute to development of PH.Conclusion:Hypoxia activates NF-κB pathway by up-regulating GLI1 to induce M1 polarization of macrophages contributes to development of PH.
