ObjectiveTo investigate the feasibility and safety of endoscopic retrograde cholangiopancreatography （ERCP） combined with oral cholangiopancreatography in the treatment of major duodenal papilla gallbladder polyps. MethodsA retrospective analysis was performed for the clinical data of eight patients with choledocholithiasis and gallbladder polyps who underwent ERCP and combined with oral cholangiopancreatography for major duodenal papilla cholecystectomy in Center of Digestive Endoscopy， Jilin People’s Hospital， from May 2022 to June 2024， and related data were collected， including the success rate of surgery， the technical success rate of gallbladder polyp removal， the superselective method of cystic duct， the time of operation， the time of gallbladder polyp removal， and surgical complications. ResultsBoth the success rate of surgery and the technical success rate of gallbladder polyp removal reached 100%， and of all eight patients， three patients used guide wire to enter the gallbladder under direct view， while five patients received oral cholangiopancreatography to directly enter the gallbladder. The time of operation was 51.88±12.34 minutes， and the time of gallbladder polyp removal was 23.13±10.94 minutes. The diameter of gallbladder polyp was 2‍ ‍—‍ ‍8 mm， and pathological examination showed inflammatory polyps in three patients， adenomatous polyps in one patient， and cholesterol polyps in four patients. There were no complications during or after surgery. The patients were followed up for 2‍ ‍—‍ ‍27 months after surgery， and no recurrence of gallbladder polyp was observed. ConclusionOral cholangiopancreatography is technically safe and feasible in endoscopic major duodenal papilla cholecystectomy.

Objective:To understand the epidemiological characteristics and spatiotemporal distribution of viral encephalitis in children and adolescents in Henan Province from 2012 to 2023.Methods:The information about viral encephalitis cases from October 1, 2012 to July 26, 2023 were collected from Zhengzhou Children's Hospital (National Children's Regional Medical Center),Henan Provincial Children's Hospital for the analyses on temporal distribution the cases, the severe illness rate, age distribution, pathogen type and imaging findings of the cases.Results:A total of 6 276 cases of viral encephalitis were included in this study after excluding cases with incomplete information. The cases mainly originated from Zhengzhou (38.96%), followed by Zhoukou (9.93%), Xuchang (8.68%), Zhumadian (7.90%) and Pingdingshan (7.39%). The cases in boys accounted for 62.13% and the cases in girls accounted for 37.87%. Most cases (72.45%) occurred in age group 7-13 years. The overall rate of severe illness cases was 4.51% from 2012 to 2023. There were significant differences in severe illness cases among different areas and years ( χ2=5.33, P=0.021; χ2=48.14, P<0.001). Enteroviruses were mainly detected (31.57%), in which Coxsackie virus was predominant (58.37%). Imaging findings showed that cerebral hemisphere damage was most common in children and adolescents with viral encephalitis (54.93%). Conclusions:From 2012 to 2023, more cases of viral encephalitis occurred in boys in Henan. Children and adolescents aged 7-13 years were the main affected group. The prevention of enteroviruses infection, especially Coxsackie virus, needs to be strengthened. Special attention should be paid to the prevention of cerebral hemisphere damage after viral encephalitis diagnosis.

Taking Peking University Cancer Hospital as an example, it made an in-depth analysis of the valuation investment model of scientific and technological achievements.Results:The study found that the valuation investment of scientific and technological achievements in hospitals includes several key links such as signing the Valuation Investment Agreement, signing the Shareholder Agreement and the Articles of Association, the registration and identification of technical contracts, the issuance of invoices, and deferred taxation. And several suggestions on how to apply this model for the transformation of scientific and technological achievements were put forward.Conclusions:Although the implementation process of scientific and technological achievements is cumbersome, the operation mode is diverse, and the ownership of equity is difficult to distinguish, the advantages are extremely obvious. It can closely combine technological capital and industrial capital, form a strong and effective technological alliance and a community of multiple interests, better use the market-oriented motivation of scientific and technological innovation, and carry out cutting-edge research in line with market prospects.

Objective:To explore the application effect of hydration therapy in patients with intermittent claudication (IC) of peripheral arterial disease, and to provide reference for clinical application.Methods:A randomized controlled trial method was used to select 86 patients with IC of peripheral arterial disease who attended the Department of Vascular Surgery of Shanxi Bethune Hospital from June to September 2023 as the study subjects by convenience sampling method, and they were divided into the control group and the intervention group by using the method of randomized numerical table, each group had 43 cases. In the control group, routine care was provided, and in the intervention group, hydration therapy was implemented on the basis of the control group. Ankle-brachial index, transcutaneous partial pressure of oxygen, and claudication distance were assessed in both groups 1d before and 6 months after the intervention.Results:Forty-two patients in each group completed the study, 21 males and 21 females, aged (61.33 ± 8.93) years in the intervention group; 24 males and 18 females, aged (61.33 ± 9.01) years in the control group. Compared with the ankle-brachial index, transcutaneous oxygen partial pressure and limp distance of the 2 groups 1 d before intervention, the differences were not statistically significant (all P>0.05), and 6 months after the intervention, the transcutaneous oxygen partial pressure of the patients in the intervention group was (37.69 ± 8.86) mmHg (1 mmHg=0.133 kPa), and that of the control group was (29.69 ± 7.79) mmHg, and the differences between the 2 groups were statistically significant ( t=4.40, P<0.05). The differences in patients′ transcutaneous partial pressure of oxygen and limp distance before and after intervention in the intervention group were -7.00 (-13.00, -1.75) mmHg and -50.00 (-100.00, 0.00) m, respectively, and in the control group were 0.01 (-1.00, 1.00) mmHg and 0.01 (-1.25, 20.00) m, respectively, and the differences between the 2 groups were statistically were statistically significant ( Z=5.59, 4.33, both P<0.05). Conclusions:Hydration therapy improves transcutaneous oxygen partial pressure values and claudication distance in patients with peripheral arterial disease IC, and improves microcirculation of the affected limbs in patients.

Objective:To conduct a scoping review to analyse the types, performance, advantages and disadvantages of cognitive function assessment tools for ICU patients, to provide a reference for the evaluation of cognitive function in ICU patients in future.Methods:A scoping review study was conducted, literature on cognitive function assessment tools for ICU patients in 9 domestic and foreign databases including China National Knowledge Infrastructure, Wanfang Database, VIP Database, China Biology Medicine disc, PubMed, Web of Science, Cochrane Library, Embase and CINAHL were systematically searched. The search period was from the establishment of the database to May 20, 2024. Literature was independently screened by 2 researchers and relevant information was extracted and summarized.Results:Totally 17 studies were included, with 9 tools for assessing cognitive function in ICU patients, including 6 questionnaires, 1 test battery, 1 assessment software, and 1 telephone interview questionnaire. All of above were generalizable tools, except for the Chinese and English versions of the John-Hopkins Adapted Cognitive Exam as ICU-specific tools. The Mini-Mental State Examination was the most widely used assessment scale.Conclusions:Appropriate assessment tools should be selected according to the specific clinical setting, but there is still a lack of specialized and standardized assessment tools for cognitive dysfunction in ICU patients. In the future, standardized tools which fit our cultural context for evaluating cognitive function in ICU patients should be developed.

BACKGROUND: Existing evidence suggests that fruit consumption is a significant influencing factor for chronic obstructive pulmonary disease (COPD), but this is unclear in the Chinese population. We examined the association of fresh fruit consumption with the risk of COPD-related hospitalization and death in a nationwide, population-based prospective cohort from China. METHODS: Between 2004 and 2008, the China Kadoorie Biobank recruited >0.5 million adults aged 30 to 79 years from ten diverse regions across China. After excluding individuals diagnosed with major chronic diseases and prevalent COPD, the prospective analysis included 421,428 participants. Cox regression was used to calculate the hazard ratios (HRs) for the association between fresh fruit consumption and risk of COPD-related hospitalization and death, with adjustment for established and potential confounders. RESULTS: During a mean follow-up of 10.9 years, 11,292 COPD hospitalization events and deaths were documented, with an overall incidence rate of 2.47/1000 person-years. Participants who consumed fresh fruit daily had a 22% lower risk of COPD-related hospitalization and death compared with non-consumers (HR = 0.78, 95% confidence interval [CI]: 0.71-0.87). The inverse association between fresh fruit consumption and COPD-related hospitalization and death was stronger among non-current smokers and participants with normal body mass index (BMI) (18.5 kg/m 2 ≤ BMI < 24.0 kg/m 2 ); the corresponding HRs for daily fresh fruit consumption were 0.78 (95% CI: 0.68-0.89) and 0.69 (95% CI: 0.59-0.79) compared with their counterparts, respectively. CONCLUSIONS High-frequency fruit consumption was associated with a lower risk of COPD in Chinese adults. Increasing fruit consumption, together with cigarette cessation and weight control, should be considered in the prevention and management of COPD.

Objective: Understanding mental health status of students with learning disabilities in Beijing to provide a basis for mental health promotion of students with learning disabilities. Methods: By means of random cluster sampling, 5 787 enrolled students in grade one and grade two of 11 public junior middle schools in Beijing were selected as the survey subjects. A self designed questionnaire was used to investigate the students’ learning disabilities and mental health status through anonymous self filling. Results: About 11.6% students self reported learning disabilities. The proportions of students with learning difficulty in mathematical reasoning and calculation were higher, 44.1% and 40.7% respectively. The reported rate of mental health problems was 38.3%. The top four of the 10 symptoms were obsessive compulsive symptoms, learning pressure, emotional instability and anxiety(2.19±0.77)(2.17±0.99)(2.09±0.90)(2.07±1.08). Compared with students without learning disabilities, students with self reported learning disabilities had poorer mental health status(OR=1.47), and learning disabilities were related to most factors of mental health. Different types of learning disabilities were associated with different mental health factors. Conclusion Mental health problems of students with learning disabilities are higher than that of students without learning disabilities. It is necessary to strengthen the mental health support for students with learning disabilities and improve their mental health.

Objective: To explore whether individualized exercise prescription can improve the walking ability of patients with lower extremity arteriosclerosis occlusion (ASO). Methods: A total of 64 ASO patients with ankle brachial index (ABI) between 0.6 and 0.9 were randomly divided into the observation group (32 cases) and the control group (32 cases), Patients in the control group received routine nursing intervention, and patients in the observation group received nursing intervention based on individualized exercise prescription, ABI and walking impaired questionnaire (WIQ) scales were measured at admission and 12 weeks after intervention. Results: There was no statistically significant difference in ABI values before and after the intervention of the control group (P > 0.05), and ABI values before and after the intervention of the observation group were 0.72 + 0.15 and 0.77 + 0.13 respectively (t=2.254, P < 0.05). There was no statistically significant difference in walking distance and walking speed before intervention (P > 0.05) in the two groups; the walking distance and walking speed after intervention in the observation group were (498.38±77.11) m and (50.44±11.27); the control group was (461.72±64.64) m and (44.02±9.86), and the differences were statistically significant (t=2.06, 2.43, P < 0.05). Conclusions Individualized exercise prescription can improve the degree of ischemia of the affected limb, improve the walking distance and walking speed of the patients, and it is convenient to implement and worthy of clinical promotion.
