OBJECTIVES: Urinary calculi are characterized by a high recurrence rate, and patients' adherence to self-management after discharge directly affects health outcomes. Traditional offline follow-up models often face problems such as poor compliance and uneven allocation of medical resources, making it difficult to meet individualized health management needs. Remote follow-up provides a novel solution to optimize long-term management, improve health literacy, and enhance clinical outcomes. This study aims to evaluate the effect of remote follow-up under an intelligent medical collaborative model on quality of life and health-promoting lifestyle in patients with urinary calculi, and to assess its short-term impact on clinical outcomes. METHODS: A total of 118 patients with urinary calculi admitted to a tertiary hospital in Hunan Province between August and November 2024 were recruited and randomly assigned to a control group (n=59) or an intervention group (n=59). The control group received routine departmental follow-up, while the intervention group underwent remote follow-up based on an intelligent medical collaborative model for one month. Assessments were conducted before discharge (T0), 15 days after discharge (T1), and one month after discharge (T2), using the Wisconsin Stone Quality of Life Questionnaire and the Health-Promoting Lifestyle Profile. At T2, the incidence of forgotten ureteral stents (FUS), ureteral stent-related complications, unplanned readmissions, and patient satisfaction were evaluated. RESULTS: No significant differences were observed between groups at T0 in baseline characteristics or outcome measures (all P>0.05). At T1 and T2, the intervention group had significantly higher health-related quality of life scores than the control group (P<0.05). Generalized estimating equation (GEE) analysis showed significant between-group effects (Wald's χ²=22.961, P<0.001), time effects (Wald's χ²=23.065, P<0.001), and interaction effects (Wald's χ²=6.930, P<0.05). Similarly, at T1 and T2, the intervention group scored significantly higher on health-promoting lifestyle than the control group (P<0.05), with significant between-group effects (Wald's χ²=22.936, P<0.001), time effects (Wald's χ²=10.694, P<0.001), and interaction effects (Wald's χ²=18.921, P<0.05). No significant differences were found between groups in the incidence of FUS, ureteral stent-related complications, or unplanned readmissions (all P>0.05). Patient satisfaction was significantly higher in the intervention group (t=4.089, P<0.001). CONCLUSIONS Remote follow-up under an intelligent medical collaborative model helps improve quality of life, promote health-oriented lifestyles, and enhance patient satisfaction among individuals with urinary calculi.

Objectives:To explore the predictive value of angiography-derived index of microcirculatory resistance(Angio-IMR)for early prognosis in patients with acute ST-segment elevation myocardial infarction(STEMI)after percutaneous coronary intervention(PCI).Methods:This multicenter study enrolled 1 629 consecutive STEMI patients who underwent successful PCI at three grade A tertiary hospitals(The Second Affiliated Hospital,Zhejiang University School of Medicine;Shengjing Hospital of China Medical University;Renji Hospital,Shanghai Jiao Tong University School of Medicine)from June 1,2017,to May 31,2020.According to postoperative Angio-IMR,patients was stratified into two groups:the Angio-IMR>40 group(n=508)and the Angio-IMR≤40 group(n=1 121).The incidence of major adverse cardiovascular events(MACE;defined as a composite endpoint including cardiac death,heart failure rehospitalization,cardiogenic shock,malignant arrhythmia,cardiopulmonary resuscitation and stent thrombosis)within 1-month post-PCI was compared between the two groups.Results:The median Angio-IMR after PCI was 32.4(22.3,42.6).The cumulative incidence of early-term MACE was significantly higher in patients with Angio-IMR>40,compared to those with Angio-IMR≤40(5.5%vs.2.3%,log-rank P<0.001).Multivariate Cox regression analysis showed that Angio-IMR>40 was an independent predictor of early-term MACE(HR=2.07,95%CI:1.20-3.58,P=0.009).The addition of Angio-IMR enhanced the predicting performance of the clinical risk model to predict early adverse outcomes(AUC:0.820 vs.0.794,P=0.043).Conclusions:In patients with STEMI after PCI,Angio-IMR can predict the occurrence of early-term MACE.The incorporation of Angio-IMR to clinical models significantly improves the model ability to predict early adverse outcomes in these patients.

OBJECTIVE To analyze quality maker （Q-marker） of Ka nggongyan soft capsule （KSC）. METHODS The fingerprints of 20 batches of KSC were established by ultra high performance liquid chromatography （UPLC）method. Similarity Evaluation System of TCM Chromatographic Fingerprint （2012 edition）were used to evaluate the similarity and confirm common peaks. The contents of norisoboldine ，leonurine hydrochloride ，forsythoside B ，acteoside，poliumoside and isoacteoside were determined by the same UPLC method. Targets and pathways related to KSC in the treatment of cervicitis were screened and analyzed by network pharmacology and molecular docking method to construct a “component-target-pathway”network，and analyze its potential Q-marker. RESULTS Twelve common peaks were identified in the fingerprints of 20 batches of KSC ，and the similarity was greater than 0.99. Six common peaks were identified ，including norisoboldine ，leonurine hydrochloride ，forsythoside B，acteoside，poliumoside and isoacteoside. The contents of the above 6 components were 1.336-1.774，0.093-0.143，4.970-5.888， 0.505-0.623，5.206-6.226 and 0.785-0.895 mg/g，respectively. By network pharmacology analysis ，14 key targets and 94 pathways were obtained ，and their binding energies to the core targets （protein kinase B 1，tumor necrosis factor ）were all less than －6.4 kJ/cal. CONCLUSIONS Six components such as norisoboldine and leonurine hydrochloride are potential Q-marker of KSC.

Objective:To investigate the effects of body mass index (BMI) levels at different baseline on the risk of new-onset acute pancreatitis (AP).Methods:The subjects were from the Kailuan Study Cohort and divided into 3 groups according to baseline BMI levels: BMI<24 kg/m 2, normal weight; BMI 24-28 kg/m 2, overweight; BMI≥28 kg/m 2, obesity. The incidence of new-onset AP in these three groups was analyzed. The survival curve was plotted by Kaplan-Meier method, the cumulative incidence was calculated and tested by log-rank method. Multivariate Cox proportional hazards regression model was used to calculate HR of baseline BMI levels for AP. Results:A total of 123 841 subjects were included and followed up for (11.94±2.13) years, during which, 395 cases were found with AP. The incidence of AP was 2.67 per 10 000 person years in total population, and the incidences of AP were 2.20, 2.72 and 3.58 per 10 000 person-years in the normal, overweight and obesity groups, respectively. The cumulative incidences of AP was 0.32%, 0.40% and 0.49% in normal, overweight and obesity groups, respectively, which showed a significant inter-group difference by log-rank test ( χ2=13.17, P<0.01). The results of multivariable adjusted Cox proportional hazards regression model analysis indicated that obesity group ( HR=1.45, 95% CI: 1.10-1.92) had a higher risk for AP compared with the normal BMI group. The subgroup analyses by age and sex showed that compared with the normal weight group,the HRs for AP in the obesity group was 1.58(95% CI:1.14-2.19) and 1.40(95% CI:1.03-1.90) among subjects younger than 60 years old and male subjects, respectively. After excluded onset AP within two years from baseline,with a control group from normal weight,the results of multivariate Cox proportional hazards regression model analysis indicated that the AP in the obesity group was 1.60 (95% CI: 1.18-2.15). Conclusion:Obesity may increase the risk of developing AP, particularly among young and middle-aged men.

Objective To study the effect of Tspan 8 on metastasis and invasion of human hepatocellular carcinomas(HCC).Methods RT-PCR and western blot were used to detect the expressions of Tspan 8 in HCC cell lines,HCC and matched nontumorous tissues.The expression of Tspan 8 was then down-regulated by LV/GFP/Tspan 8 in HCC cells.The expressions of Tspan 8 mRNA and protein were determined by RT-PCR and Western blot assay,respectively.The proliferation was examined by MTT,the expression of AMDM12 was assessed by Western blot,and the invasion ability of HCC cells was evaluated by transwells.Results A high level of Tspan 8 was found in high metastatic potential HCC cells,and the expression of Tspan 8 in HCC tissues was much higher than that in the matched nontumorous tissues. Down-regulation of Tspan 8 had no influence on the proliferation of HCC cells (P＞0.05),while it inhibited the expression of ADAM12 and the invasive ability of HCC cells (P＜0.01,P＜0.01 respectively).Conclusion Tspan 8 played an important role in invasion and metastasis of human hepatocellular carcinomas and down-regulation by LV/GFP/Tspan 8 inhibited the invasiveness of human hepatocellular carcinoma cells.

Objective To study the role of bone morphogenetic protein-7 in the osteogenic differentiation of periosteal cellsin vitro. Methods Periosteal cells, obtained from adult tibial periosteum, were cultured by routine method in vitro, and divided into two groups. One group cultured with BMP7 and the supplements of 100 nmol dexametasone, 10 mmol b-glycerophosphate and 50 mg/mL L-ascorbic acid (BMP7 group), the other cultured with the supplements alone as the control (control group). Ultrastructure and morphological changes of periosteal cells were observed by contrast phase microscope and electron microscope. In order to test the expression of markers of osteoblastic differantiation in periosteal cells, involved mineralized node and alkaline phosphatase. Each group was tested at the time of 5 d, 10 d, 15 d, 20 d, respectively, using ALP kit stain and Von Kossa stain with 3 samples at each time. Results The periosteal cells cultured by routine method and induced into osteoblast differentiation with BMP7 were both growing well, in vitro. Microscope observations showed that the periosteal cells were spindle-shaped, well-stacked, transparent and three-dimensional in the early stage, and cube-shaped or puncheon shaped in the mitotic phase, gradually became wide shuttle and irregular shape with a lot secretion in telophase. The positive cells were visible by the ALP kit staining and Von Kossa staining of calcium nodules at 5 d, 10 d, 15 d and 20 d in both groups.A difference of positive rate at each time point was found between BMP7 group and control group at 5 d, 10 d, 15 d, 20 d, and the difference was statistically significant (P ＜ 0.01). Conclusion It displayed well regeneration and osteogenesis ability in the periosteal cell. BMP7 has definite osteo-inductive activity, which can obviously enhance the proliferation and ossifyng differentiation of periosteal cells.
