With the rapid development of large language models and related technologies, various forms of patient modeling have emerged, including virtual patients, synthetic patients, artificial intelligence patients, and digital twin patients. Although these forms all share the core objective of patient simulation, they exhibit significant differences in theoretical ontology, data sources, modeling logic, and application orientation. Based on the abstraction levels of simulation objects and system mapping logic, this study systematically compares five paradigms—standardized patients, virtual patients, synthetic patients, AI patients, and digital twin patients—to clarify their conceptual boundaries and technical positioning. The findings indicate that these paradigms represent distinct modeling pathways: behavioral reproduction, scenario simulation, data generation, cognitive interaction, and individual system mapping, respectively. By constructing a multidimensional comparative framework, this study provides a theoretical foundation for the conceptual standardization of patient modeling and the strategic deployment of intelligent healthcare systems.

Objective To apply the evidence mapping system,the evidence of traditional Chinese medicine related research on chronic obstructive pulmonary disease intervention was identified,described and evaluated.Methods CNKI,Wanfang,VIP,SinoMed,PubMed,Web of Science,Cochrane Library and other databases were searched before November 2023 to obtain systematic review/meta-analysis/network meta-analysis.The AMSTAR 2 scale was used to evaluate the quality of the included studies.Results A total of 111 systematic reviews/Meta-analysis/network Meta-analysis were included.In the observation group,most of them were treated with traditional Chinese medicine decoction,and the treatment methods were mostly warming,eliminating,clearing and so on.Traditional Chinese medicine treatment of chronic obstructive pulmonary disease could increase lung function and 6-minute walking distance(6WMD),improve efficiency and arterial oxygen partial pressure(PaO2),relieve clinical symptoms and improve the quality of life of patients.According to the evaluation results of AMSTAR 2 scale,the overall methodological quality of systematic review/Meta-analysis was not high,and there was a lack of sufficient evidence to support the efficacy of TCM treatment.Conclusion Traditional Chinese medicine has a certain effect on the treatment of chronic obstructive pulmonary disease,but the quality of evidence included in the literature needs to be improved.In the future,high-quality research should be carried out to provide evidence-based evidence.

Objective To investigate the prevalence of specific IgE antibodies against Alternaria alternata and Aspergillus fumigatus in serum samples from clinical allergy patients across selected provinces in China.Methods Data on specific IgE antibodies for Alternaria A.and Aspergillus F.were collected from 20 hospital laboratories in 17 cities spanning 11 provinces.The study analyzed the levels of specific IgE and their variations across different provinces and seasons.Results A total of 27 471 cases of Alternaria A.and 32 843 cases of Aspergillus F.specific IgE data were included.The national average positive rate of Alternaria A.IgE was 10.40%,with the highest rate of 22.68%in Jiangsu and the lowest rate of 2.06%in Guangxi.For Aspergillus F.specific IgE,the average positive rate was 4.24%,with Hubei province having the highest rate(7.25%)and Hunan province the lowest(1.23%).The difference in IgE levels for both Alternaria A.and Aspergillus F.among provinces were statistically significant(H=9 955,16 993,all P<0.0001).Among patients,5.85%had Alternaria A.specific IgE levels at grade 3 or above,while only 0.57%had Aspergillus F.specific IgE levels at this level.When examining seasonal variations using data from Liaoning,Hunan and Anhui provinces,significant seasonal changes were observed for both Alternaria A.and Aspergillus F.IgE antibodies(HAlternaria A=347.6,338.0,401.3,HAspergillus F=196.6,133.7,231.7,all P<0.0001).Conclusion The sensitization to Alternaria A.and Aspergillus F.exhibits distinct geographical characteristics and vary significantly with seasons.Given the relatively high IgE levels associated with Alternaria A.,it should be given adequate clinical attention.

OBJECTIVE To evaluate the efficacy and safety of guideline-directed medical therapy （GDMT） combined with vericiguat in treating heart failure with reduced ejection fraction （HFrEF）. METHODS A retrospective study was conducted on 346 patients with HFrEF who received standardized diagnosis and treatment at the First People’s Hospital of Changzhou from January 2023 to May 2024. They were divided into standard treatment group （n＝215） and vericiguat group （n＝131）. Patients in the standard treatment group received GDMT， while patients in the vericiguat group received GDMT combined with vericiguat. Propensity score matching （PSM） was used to balance confounding factors between two groups， and the effectiveness （including outcome and prognostic indicators） and safety （occurrence of adverse events） of both groups were evaluated. Kaplan-Meier survival curves for primary and secondary outcome events were drawn， and the influential factors of primary outcome events were screened through univariate and multivariate Cox regression analysis. RESULTS After PSM， there were 100 patients in the standard treatment group and 100 patients in the vericiguat group， and there was no statistically significant differences in baseline data between two groups （P＞0.05）. During a 1-year follow-up， there were statistically significant differences in the cumulative incidence of major outcome events between the standard treatment group and the vericiguat group， cumulative incidence of hospitalization events due to heart failure， changes in N-terminal pro-B-type natriuretic peptide levels before and after treatment between the standard treatment group and the vericiguat group （P＜0.05）. There was no statistically significant difference in the incidence of adverse events between the two groups （P＞0.05）. Multivariate Cox regression analysis results showed that left ventricular ejection fraction ≤35% was a risk factor for the occurrence of major outcome events within 1 year [hazard ratio （HR）＝ 2.090， 95% confidence interval （CI）： 1.175-3.718， P＝0.012]， while the use of vericiguat was a protective factor for the occurrence of major outcome events within 1 year （HR＝0.505， 95%CI： 0.284-0.899， P＝0.020）. CONCLUSIONS Compared with GDMT， GDMT combined with vericiguat can improve the clinical symptoms and prognosis of HFrEF patients， and has good safety.

Objective:To evaluate the long-term effectiveness of lingual mucosal graft ureteroplasty (LMGU) for managing long-segment (≥5 cm) ureteral strictures in a multi-institutional cohort of patients.Methods:A multi-center retrospective case series study was conducted on clinical data from 42 patients undergoing LMGU for long-segment ureteral strictures (≥5 cm) across five institutions between February 2017 and June 2024. The cohort comprised 31 males and 11 females, with an age of (43.4±12.0) years (range: 15 to 64 years) and a body mass index of (24.6±2.6) kg/m2 (range: 16.0 to 30.0 kg/m2). Strictures involved the left ureter in 24 cases and right ureter in 18 cases, demonstrating a stricture length of (6.4±1.5) cm (range: 5.0 to 11.5 cm). Surgical interventions included either onlay ureteroplasty or augmented anastomotic ureteroplasty, selected according to intraoperative findings. Intraoperative parameters, postoperative complications, and follow-up outcomes were analyzed.Results:Laparoscopic surgery was performed in 22 cases and robot-assisted surgery in 20 cases. Among the 42 patients, 22 underwent onlay ureteroplasty while 20 received augmented anastomotic ureteroplasty. The graft length was (5.9±1.8) cm (range: 3.0 to 12.0 cm), operative time (191.5±55.6) minutes (range: 105.0 to 350.0 minutes), and intraoperative estimated blood loss (86.7±73.6) ml (range: 10.0 to 400.0 ml). All procedures were successfully completed without conversion to open surgery. The postoperative hospital stay was (7.6±2.0) days (range: 4.0 to 15.0 days), with double-J stent removal at 6 to 8 weeks postoperatively. During a follow-up of (49.1±25.0) months (range: 12.0 to 99.0 months), no stricture recurrence was observed in any patient.Conclusion:LMGU is a safe, feasible, and effective long-term technique for managing long-segment (≥5 cm) ureteral strictures.

Objective:To evaluate the clinical performance of high-risk human papillomavirus (HR-HPV) genotyping in cervical cancer screening.Methods:Between June and July 2017, a prospective cervical cancer screening cohort was established in Xiaye Town, Jiyuan City, Henan Province, China by recruiting 3 254 women aged 21 to 64 years. At baseline screening, cervical exfoliated cell specimens were collected for HR-HPV genotyping and liquid-based cytology testing. Follow-ups were conducted over a 3-year period, with cytology testing in the first and second years and both HR-HPV genotyping and cytology testing in the third year. Women meeting the referral criteria were referred for colposcopy, with cervical biopsy and histopathological diagnosis performed as necessary. The endpoint was defined as cervical intraepithelial neoplasia grade 2 (CIN2) or higher confirmed by histopathological diagnosis. The sensitivity and specificity for detecting CIN2 or higher lesions of HR-HPV genotyping were calculated, as well as the cumulative risk of developing CIN2 or higher lesions over the 4-year study period in women with different baseline HR-HPV genotyping results.Results:A total of 2 741 women were included in the statistical analysis. Baseline HR-HPV genotyping detected 453 HR-HPV positive cases (16.53%), including 98 HPV 16/18 positive cases (3.58%) and 355 other HR-HPV positive cases (12.95%). During the 4-year period, 83 cases of CIN2 or higher were diagnosed. The sensitivity and specificity of baseline HR-HPV positivity for CIN2 or higher were 89.16% (95% CI: 80.66%-94.19%) and 85.74% (95% CI: 84.36%-87.02%), respectively. The corresponding rates for HPV 16/18 positivity were 43.37% (95% CI: 33.24%-54.09%) and 97.67% (95% CI: 97.02%-98.18%). The 4-year cumulative absolute risk of CIN2 or higher was highest in the HPV 16/18 positive group (36.73%, 95% CI: 27.85%-46.62%), followed by other HR-HPV positive groups (10.70%, 95% CI: 7.87%-14.38%), and the HR-HPV negative group was the lowest (0.39%, 95% CI: 0.19%-0.76%). Conclusions:HR-HPV genotyping testing exhibits high sensitivity and specificity for detecting CIN2 or higher lesions in cervical cancer screening. It also provides a scientific basis for stratifying the individual risk of developing CIN2 or higher lesions to guide subsequent management. Therefore, the HR-HPV genotyping testing can be considered as an effective method for cervical cancer screening.
