Objective To analyze the epidemiological characteristics of hepatitis E (HE) in Huai'an City from 2015 to 2024, and construct and validate the prediction effect of the Seasonal Autoregressive Integrated Moving Average (SARIMA) model, and to provide a scientific basis for HE prevention and control. Methods Data of reported HE cases in Huai'an City from January 2015 to December 2024 were extracted from the National Disease Control and Prevention Information System. Descriptive epidemiological methods were used to analyze the temporal, regional and population distribution characteristics of HE incidence. After data preprocessing, stationarity test and randomness test, the SARIMA model was constructed. The optimal model was selected by minimizing the Akaike Information Criterion (AIC). The model performance was evaluated by adjusted R-squared (Adj R²) and root mean square error (RMSE). The monthly incidence rate of HE in Huai'an City in 2025 was predicted and compared with the actual incidence data to validate the model. Results A total of 1 713 HE cases were reported in Huai'an City from 2015 to 2024, showing a fluctuating upward trend. Huaiyin District (339 cases) and Lianshui County (334 cases) were high-incidence areas. The cases were mainly concentrated in people aged 45 and above (83.3%), males (gender ratio 2.37:1) and farmers (70.8%). The optimal model was SARIMA (1,1,1)×(2,0,1)₁₂, with residual as white noise sequence. There was no statistical difference between the actual incidence and predicted value from January to August 2025 (P>0.05). Conclusion HE incidence in Huai'an has obvious aggregation and temporal fluctuation characteristics. The SARIMA model has a good prediction effect, which can provide reference for formulating targeted prevention and control strategies.

Objective:To review the diagnosis, treatment and quality of life of patients with primary immune thrombocytopenia (ITP) in seven medical centers in some areas of Hubei Province.Methods:A retrospective analysis was conducted on age, disease course, symptoms, diagnosis, and treatment status (including testing items, drug selection, and adverse reactions) of patients with ITP in seven medical centers in Hubei Province from January 2020 to December 2022. An online survey was conducted on the quality of life of patients using the ITP Patient Assessment Questionnaire (ITP-PAQ) .Results:Among the 1033 patients, those with newly diagnosed, persistent, and chronic ITP accounted for 39.8%, 19.1%, and 41.1%, respectively. Most patients exhibit varying degrees of bleeding. Regarding treatment, corticosteroids and thrombopoietin drugs are the most commonly chosen treatment drugs for ITP, and the adverse reactions to treatment mainly include diarrhea, liver dysfunction, and thrombosis. The ITP-PAQ survey of 125 patients revealed that ITP significantly impairs their life quality. Patients with ITP scored significantly lower in fatigue, sleep, fear, exercise, work, and social aspects.Conclusion:A relatively high proportion of patients with ITP progressed to the chronic phase. Corticosteroids and thrombopoietin drugs are the two main treatment drugs for ITP patients. The quality of life of patients with ITP is significantly reduced in multiple dimensions.

Objective To develop a systematic and scientific assessment-adaptation-evaluation framework for wheelchair cushions.Methods A mixed-methods approach integrating literature review,qualitative interviews and Delphi expert consultation was employed.First,27 relevant studies were identified through systematic literature searches,comprehensively synthesizing wheelchair cushion types,performance indicators,key assessment/adaptation elements and evalua-tion methods.Second,semi-structured interviews were conducted with 24 wheelchair users and six assistive tech-nology specialists.Interview transcripts were analyzed using Colaizzi's phenomenological analysis to extract themes and deeply explore user needs and practitioner experiences.Based on the literature and interview find-ings,the research team developed a preliminary protocol comprising an assessment form,an adaptation process table and an effectiveness evaluation form.Finally,20 multidisciplinary experts participated in a two-round Del-phi consultation.Experts rated the importance of items using a 5-point Likert scale.Consensus was analyzed us-ing Kendall's W coefficient and the coefficient of variation(CV),supplemented by mean importance scores and full-score frequency to refine the protocol.Results The consultation demonstrated excellent expert engagement(100%response rate)and strong authority(Cr=0.90).The finalized protocol comprised of an assessment form(four primary domains/21 secondary items),an ad-aptation protocol(two primary domains/eight secondary items)and an evaluation form(two primary domains/15 secondary items).Statistical analysis revealed Kendall's W=0.20(P<0.05),mean importance scores of(4.48±0.72),CV=(0.15±0.05),and full-score frequency of(60.80±16.39)%,indicating acceptable consensus.Conclusion The assessment-adaptation-evaluation method for wheelchair cushions constructed in this study is scientific,comprehensive and operable,and can provide a standardized tool for clinical personalized adaptation.Future studies should enhance the applicability of the method in diverse clinical settings.

Objective To explore the efficacy and safety of 0.02％atropine eye drops for the treatment of nearwork-induced transient myopia(NITM)in adolescents.Methods A total of 131 adolescents with NITM were randomly divided into experimental(receiving 0.02％atropine eye drops)and control(receiving placebo)groups.Changes in the initial NITM values before medication and at 14 and 30 days after medication were observed.Alterations in intraocular pressure and accommodation amplitude were monitored,and the occurrence of complications,such as photophobia and near vision impairment,were recorded.Results The baseline NITM did not differ significantly between the two groups.On day 14 and day 30,the NITM values in the experimental group were significantly reduced compared to the baseline,with differences of 0.31 D±0.20 D and 0.30 D±0.16 D,which were significantly greater than those in the control group(0.21 D±0.98 D and 0.20 D±0.18 D,P＜0.001).The efficacy rate of NITM treatment in the experimental group was 84.4％,which was sig-nificantly higher than that in the control group(29.9％).After 30 days of treatment,no severe systemic or ocular adverse reactions were observed in the experimental group.Mild photophobia was the main adverse reaction.Conclusion 0.02％atropine eye drops can effec-tively reduce the initial NITM value in adolescents within a month of its use,with no severe complications and good tolerance.A clinical trial of atropine eye drops at different concentrations to reduce NITM over a longer period is warranted.

Objective:To evaluate the role of ubiquitin-specific peptidase 22 (USP22) in myocardial ischemia-reperfusion (I/R) injury in diabetic mice.Methods:Seventy-eight SPF male C57BL/6 mice, aged 6-8 weeks, were divided into 6 groups using a random number table method: sham operation group (Sham group, n=12), type 1 diabetes mellitus + sham operation group (T1D+ Sham group, n=12), myocardial I/R injury group (I/R group, n=12), type 1 diabetes mellitus + myocardial I/R injury group (DI/R group, n=12), type 1 diabetes mellitus + myocardial I/R injury + empty vector group (DI/R+ V group, n=15), and type 1 diabetes mellitus + myocardial I/R injury + USP22 overexpression group (DI/R+ U group, n=15). Type 1 diabetes mellitus was induced by intraperitoneal injection of streptozotocin-citrate buffer. Myocardial I/R was induced by ligation of the left coronary artery. At 1 day before developing the myocardial I/R injury model, DI/R+ U group and DI/R+ V group received an intramyocardial injection of USP22 overexpression plasmid or empty vector plasmid, respectively. At 24 h of reperfusion, cardiac function was assessed using the echocardiography to measure the left ventricular ejection fraction and left ventricular fractional shortening. The mice were then sacrificed, and their hearts were harvested for measurement of the myocardial infarct size, for microscopic examination of pathological changes (using HE staining) and for determination of the apoptosis rate (TUNEL staining), reactive oxygen species(ROS) activity (DHE staining), and USP22 expression (by Western blot, immunofluorescence, and immunohistochemistry). Proteomic analysis was performed to identify downstream proteins regulated by USP22, and protein-protein interactions were investigated using co-immunoprecipitation. Results:Compared with Sham group, the cardiac function indices were significantly decreased, the apoptosis rate of myocardial cells and ROS activity were increased, and USP22 expression in myocardial tissues was down-regulated in I/R group ( P<0.05). Compared with I/R group, the percentage of myocardial infarct size was significantly increased, the cardiac function indices were decreased, the apoptosis rate of myocardial cells and ROS activity were increased, and USP22 expression in myocardial tissues was up-regulated ( P<0.05), and the pathological damage to myocardial tissues was aggravated in DI/R group. Compared with DI/R+ V group, the percentage of myocardial infarct size was significantly decreased, the cardiac function indices were increased, the apoptosis rate of myocardial cells and ROS activity were decreased, and USP22 expression in myocardial tissues was up-regulated ( P<0.05), and the pathological damage to myocardial tissues was alleviated in DI/R+ U group. The results of proteomics combined with co-immunoprecipitation experiments showed an interaction between calponin 1 and USP22. Conclusions:During myocardial I/R injury in diabetic mice, USP22 may act as an endogenous protective mechanism, and calponin 1 might be a downstream mechanism through which USP22 exerts its protective effects.

Objective:To evaluate the clinical value of the frozen section assessment of surgical margin in preserving urinary continence and erectile function during robotic radical prostatectomy (RARP).Methods:From Feb. 2022 to Jul 2023, 11 patients underwent RARP using intrafascial dissection technique and frozen section assessment in Beijing United Family Hospital. The median age was 64(61, 69)years, the median PSA was 8.0(6.0, 11.2)ng/ml, and the median IIEF-5 was 17.5(10.3, 22.0). All the patients were diagnosed with prostate cancer and PSMA-PET/CT showed negative for metastasis. The da Vinci Si platform, 4-arm, transabdominal anterior approach was applied in all cases. The prostate specimen was removed from the umbilical incision and submitted to the pathology department for frozen section assessment. If the frozen section assessment showed cancer in the surgical margin, a secondary resection of the ipsilateral periprostatic fascia and neurovascular bundle (NVB) was performed. Totally, 3 cases underwent secondary resection, who underwent unilateral NVB-sparing, and the other 8 cases underwent bilateral NVB-sparing surgery. In follow-up, the PSA, urinary continence and erectile function was assessed and recorded.Results:All the surgeries of 11 cases were successful, without convertion to open surgery. The median operation time was 260(225, 285)minutes, the median blood loss was 200(100, 300)ml, the median hospital stay was 4(3, 5)days. There was no over Clavien Dindo Ⅱ perioperative complications.The median catheter indwelling time was 12(10, 14) days, with 10 cases achieving full continence upon catheter removal. The median follow-up time was 10 months. The median PSA level at 3 months, 6 months and 9 months postoperatively was 0.017(0.006, 0.170)ng/ml, 0.015(0.006, 0.390)ng/ml, and 0.007(0.006, 0.650)ng/ml respectively. The median IIEF-5 at 3 months, 6 months and 9 months postoperatively was 0.017(0.006, 0.170)ng/ml, 0.015(0.006, 0.390)ng/ml, 0.007(0.006, 0.650)ng/ml respectively.The median IIEF-5 at 3 months, 6 months and 9 months post-operation was 5.0(4.5, 11.0), 7.5(4.3, 17.5), and 9.5(6.0, 17.5)respectively.Conclusions:The RARP combined with frozen section assessment of surgical margin has excellent safety profile and can achieve favorable clinical value in tumor control, NVB preserving, urinary continence and erectile function.

Objective:To observe any regulatory effect of a pulsed electromagnetic field (PEMF) on A2A adenosine receptors (A2ARs) in the nucleus pulposus of rats with intervertebral disc degeneration (IDD), and to explore any combination with the A2ARs′ agonist-mediating ROS/PI3K/Akt signaling pathway.Methods:Fifty Sprague-Dawley rats were randomly divided into a control group, an intervertebral disc degeneration group (the model group), an A2AR agonist CGS-21680 treatment group (the agonist group), a PEMF group and a PEMF combined with CGS-21680 treatment group (the observation group). IDD was modeled in all except the rats in the control group. 100μL of CGS-21680 (100μg/kg) was injected into the L 5-6 intervertebral discs of the agonist group, while the PEMF group was given 30 minutes of PEMF intervention daily for 14 days at 1.5mT and 75Hz with a pulse width of 150μs. The observation group was injected with CGS-21680 and then given the same PEMF intervention. Primary nucleus pulposus cells from each group (50ng/mL) were cultured and the expressions of 8-OHDG, SOD, MDA and ROS were detected by immunohistochemistry, immunofluorescence or with an ELISA kit. The A2AR, PI3K, AKT and p-AKT protein levels were detected using western blotting. Results:The nucleus pulposus cells and the annulus fibrosus were obviously wrinkled, necrotic and broken in the model group but the annulus fibrosus was intact and the nucleus pulposus was almost normal in the observation group. Compared with the model group, the levels of SOD and A2AR, PI3K, p-AKT and AKT protein were higher in the agonist, PEMF and observation groups, while the expressions of MDA, ROS and 8-OHDG were weaker. The ROS level in the observation group was significantly lower than that in the agonist and PEMF groups, and the phosphorylation level of p-AKT in the observation group was significantly higher than in the agonist and PEMF groups. The average levels of SOD, A2AR, PI3K, p-AKT and AKT protein in the nucleus pulposus cells of the agonist, PEMF and observation groups were significantly higher than the IL-1β group′s average, while the average levels of MDA, ROS and 8-OHDG were significantly lower. The ROS levels in the observation group were significantly lower than in the agonist and PEMF groups, while the A2AR protein content and p-AKT phosphorylation in the observation group were significantly greater. The average Bax levels in the nucleus pulposus cells of the agonist, PEMF and observation groups were significantly lower than that in the IL-1β group, and the expression of Bcl-2 was significantly increased. There was significantly less apoptosis observed in the observation group than in the agonist and PEMF groups, while the expression of Bcl-2 was significantly higher.Conclusions:PEMF plays an anti-oxidative stress role by up-regulating A2AR activity and reducing ROS generation. Treatment with PEMF and A2AR agonist could further activate the phosphorylation of PI3K/Akt, down-regulate Bax and up-regulate Bcl-2, thus inhibiting the apoptosis of nucleus pulposus cells and alleviating the malignant progression of IDD.
