ObjectiveTo investigate the current situation of health communication carried out by medical institutions in Shanghai through new media platforms such as WeChat， Weibo， Toutiao， Douyin， Kuaishou， Bilibili and WeChat Videos， and to propose targeted measures. MethodsBased on the systematic collection of new media accounts of medical institutions in Shanghai， and through the combination of keyword screening and manual audit， health communication data of medical institutions on new media platforms were determined. ResultsData from 1 117 new media accounts of 162 medical institutions in Shanghai were collected， including 610 WeChat official accounts， 105 WeChat video accounts， 89 Weibo accounts， 18 Bilibili accounts， 198 Douyin accounts， 37 Toutiao accounts， and 60 Kuaishou accounts， totaling 111 853 posts. After keyword sorting and manual screening， a total of 66 761 health science posts were collected， with WeChat Official Accounts， Douyin， and Weibo having the top three highest number of posts. Video-based new media such as Douyin， WeChat Videos， Kuaishou， and Bilibili had a better communication impact than text and image-based new media like WeChat Official Accounts， Weibo， and Toutiao. Among them， Douyin and Toutiao were the best platforms for video and text-image-based new media， respectively. ConclusionMedical institutions in Shanghai recognize the importance of new media in health communication and have made full use of various media platforms to carry out health communication，having a certain impact on health education. In the future， medical institutions should choose appropriate platforms based on target audiences and content characteristics， fully leverage the advantages of various platforms， explore innovative communication strategies， promote the dissemination of health knowledge， and enhance the health literacy of the public.

Diabetes mellitus is a complex metabolic disease involving multiple organ systems in the body.In recent years,its global incidence rate has increased year by year.In China,the blood glucose control of patients with diabetes mellitus who receive oral hypogly-cemic agents or insulin treatment remains poor.In the early disease stages,exercise is important to control blood glucose levels.Recently,many studies have found that the occurrence of type 2 diabetes mellitus was related to declining levels of irisin,an exercise-related muscle factor.Furthermore,studies have found that irisin improved insulin resistance,promoted the production of pancreatic isletβcells,and affected the body's glucose and lipid metabolism.In addition,its levels were also implicated in the occurrence of various complications,such as diabetic nephropathy and diabetes-related cardiovascular diseases.This article summarizes and analyzes the role of irisin in the occurrence and development of diabetes mellitus and further describes its impact and mechanism on various diabetic complications.

Objective:To summarize the clinical and pathological characteristics, treatment methods, and prognosis of papillary renal neoplasm with reverse polarity (PRNRP).Methods:The clinical and pathological data of six pathologically confirmed PRNRP patients admitted to Renji Hospital affiliated with Shanghai Jiaotong University School of Medicine from August 2022 to August 2023 were retrospectively analyzed. Among them, three were male and three were female, with an average age of (55.3±10.5) years old. All six cases were incidentally discovered during health examinations. Preoperative contrast-enhanced CT scans showed tumors with cortical phase manifestations of uneven enhancement, avascularity, and indistinct borders, with CT values of (85.6±18.7) HU. In the corticomedullary phase, the CT values showed mild elevation, with an average of (94.3±4.7) HU. In the delayed phase, the tumor boundaries were clear, and the enhancement degree was significantly lower than that of the surrounding renal cortex and medulla, with a tumor CT value of (86.3±11.9) HU. The pseudocapsule of the tumor was not clearly displayed on contrast-enhanced CT scans. All cases underwent partial nephrectomy, including two cases of robot-assisted laparoscopic partial nephrectomy and four cases of laparoscopic partial nephrectomy.Results:Postoperative pathological measurements revealed a maximum tumor diameter ranging from 6 to 15 mm, with an average diameter of (11.0±3.5) mm. All six cases were classified as pT 1aN 0M 0 stage. Microscopically, the tumors exhibited branching papillary structures with eosinophilic cytoplasm, and the tumor cells displayed low-grade nuclei located at the top of the cytoplasm and away from the basal membrane. Immunohistochemical analysis showed diffuse strong positivity for GATA3 and CK7, while CA-Ⅸ expression was negative. The median follow-up time after surgery was 10(9, 13) months, and no tumor recurrence or metastasis was observed. Conclusions:PRNRP is a rare, low-grade malignant papillary renal tumor. Contrast-enhanced CT scan has characteristic features of avascularity. Pathological morphological features are low-grade nuclei located at the top of the cytoplasm and far away from the basal membrane, forming a "reverse polarity". The immunophenotype shows positive expression of GATA3 and CK7. Partial nephrectomy is the recommended treatment approach, and the postoperative prognosis is favorable.

ObjectiveTo investigate the effects of health distress on depression and anxiety among the middle-aged and elderly hearing-impaired people, and to explore the mediating effect of social capital, so as to provide an evidence for the implementation of appropriate interventions. MethodsA face-to-face self-designed questionnaire survey was conducted on 271 middle-aged and elderly hearing-impaired people aged 50 years and above in Shanghai from September 2021 to February 2022, including the general information of the subjects, social capital scale, hospital anxiety and depression scale, and health distress scale. The higher the total scores of the social capital scale, the higher level of social capital. Higher scores on the hospital anxiety and depression scale indicate more severe anxiety and depression, and scores >7 points were used to define an anxiety or depression status. The higher scores of the health distress scale, the worse the health condition of the respondents. Univariate and multivariate linear regression models were used to investigate the effects of health distress on depression and anxiety, and the mediating effects were used to test the mediating role of social capital between health distress and depression and anxiety. ResultsThe mean scores of depression, anxiety, social capital and health distress among the middle-aged and elderly hearing-impaired people aged 50 years and above were (11.063±5.892), (58.391±15.273) and (6.384±4.787) points, respectively. Health distress scores were positively correlated with social capital scores, health distress was positively correlated with depression and anxiety, while social capital was negatively correlated with depression and anxiety (all P<0.05). Social capital had masking effects on the relationship between health distress, depression and anxiety (all P<0.05), which accounted for 24.11% and 18.93% in the effects of depression and anxiety, respectively. ConclusionThe levels of depression and anxiety are higher among the middle-aged and elderly hearing-impaired people aged 50 years and above, and health distress can affect the levels of depression and anxiety through social capital. Health workers should take measures to reduce health distress and improve social capital among the middle-aged and elderly hearing-impaired people, so as to further alleviate the occurrence and development of depression and anxiety.

As a metabolic disease,obesity increases the risk of many chronic metabolic diseases;in fact,it is an epidemic in the 21st cen-tury.Exercise is an important means of controlling and treating obesity.Irisin,a myocyte cytokine,was discovered and reported in 2012;it is regulated by exercise and involved in the browning of adipose tissue.A recent discovery is irisin's ability to improve obesity,which is embodied in its effect on glucose and lipid metabolism.Irisin can induce the browning of white fat;promote glucose homeostasis;resist the damage of fat cells caused by inflammation,oxidative stress,and other factors;inhibit insulin resistance;and improve glucose,lipid metabolism,and obesity.This review addresses the role of irisin in improving glucose levels,lipid metabolism,and obesity,as well its role in regulating exercise.Further,the prospect of future research is discussed.

MethodsDuring September 2021 to February 2022， 271 middle-aged and elderly deaf people aged 50 years and over in Shanghai were investigated face-to-face by general questionnaire， chronic disease self-management study measures， self-efficacy scale， social capital questionnaire， hospital anxiety and depression scale， health disturbance scale. ResultsThe mean score of chronic disease self-management behavior was 32.107±7.527. Gender， frequency of searching health knowledge by mobile phone， whether to eat fruit， self-efficacy and social capital were influencing factors of chronic disease self-management behaviors， which could explain 37.04% of the variance. ConclusionThe chronic disease self-management behavior of the middle-aged and elderly deaf people aged 50 years and over is low and needs to be improved. We can promote the middle-aged and elderly deaf people to form the good self-management behavior by improving their self-efficacy， improving their level of social capital and forming good living habits.

Objective:To investigate the safety of minimally invasive liver resection for resectable hepatocellular carcinoma (HCC) complicated with portal hypertension.Methods:The propensity score matching and retrospective cohort study was conducted. The clinicopathological data of 807 patients with resectable HCC who underwent minimally invasive liver resection in 8 medical centers, including Sir Run Run Shaw Hospital, Affiliated with the Zhejiang University School of Medicine et al, from June 2011 to November 2022 were collected. There were 670 males and 137 females, aged 58(50,66)years. Of the 807 patients, 173 cases with portal hypertension were divided into the portal hypertension group, and 634 cases without portal hypertension were divided into the non-portal hypertension group. Observation indicators: (1) propensity score matching and comparison of general data of patients between the two groups after matching; (2) intraoperative and post-operative situations; (3) subgroup analysis. Propensity score matching was done by the 1:1 nearest neighbor matching method, with the caliper setting as 0.001. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the rank sum test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was constructed using the non-parameter rank sun test. Results:(1) Propensity score matching and comparison of general data of patients between the two groups after matching. Of the 807 patients, 268 cases were successfully matched, including 134 cases in the portal hypertension group and 134 cases in the non-portal hypertension group. The elimination of the tumor diameter and robot-assisted surgery confounding bias ensured comparability between the two groups after propensity score matching. (2) Intraoperative and postoperative situations. The occlusion time of porta hepatis, cases with intraoperative blood transfusion, cases with postoperative complication, cases with complication >Ⅱ grade of Clavien-Dindo classification, cases of Clavien-Dindo classification as Ⅰ grade, Ⅱ grade, Ⅲ grade, Ⅳ grade, cases with liver related complication were 27.0(15.0,43.0)minutes, 33, 55, 15, 13, 29, 14, 1, 37 in the portal hypertension group, versus 35.0(22.0,60.0)minutes, 17, 25, 5, 14, 9, 4, 1, 13 in the non-portal hypertension group, showing significant differences in the above indicators between the two groups ( Z=-2.15, χ2=6.30, 16.39, 4.38, 20.72, 14.16, P<0.05). (3) Subgroup analysis. Results of subgroups analysis showed that in cases with major live resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 243.5(174.6,296.3)minutes, 200.0(150.0,600.0)mL, 7.5(6.0,13.0)days in the portal hypertension group, versus 270.0(180.0,314.5)minutes, 200.0 (75.0,450.0)mL, 7.0(5.5,10.0)days in the non-portal hypertension group, showing no significant difference in the above indicators between the two groups ( Z=-0.54, -1.73, -0.92, P>0.05). In cases with non-major live resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 170.0(120.0,227.5)minutes, 100.0(50.0,200.0)mL, 8.0(5.0,10.0)days in the portal hypertension group, versus 170.0(120.0,227.5)minutes, 100.0(50.0,200.0)mL, 7.0(5.5,9.0)days in the non-portal hypertension group, showing no significant difference in the above indicators between the two groups ( Z=-1.39, -0.10, 1.05, P>0.05). In cases with anatomical liver resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 210.0(150.0,285.0)minutes, 150.0(50.0,200.0)mL, 8.0(6.0,9.3)days in the portal hypertension group, versus 225.5(146.3,306.8)minutes, 100.0(50.0,250.0)mL, 7.0(6.0,9.0)days in the non-portal hypertension group, showing no significant difference in the above indica-tors between the two groups ( Z=-0.75, -0.26, -0.91, P>0.05). In cases with non-anatomical liver resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 173.5(120.0,231.5)minutes, 175.0(50.0,300.0)mL, 7.0(5.0,11.0)days in the portal hyper-tension group, versus 186.0(123.0,262.5)minutes, 100.0(50.0,200.0)mL, 7.0(5.0,9.5)days in the non-portal hypertension group, showing no significant difference in the above indicators between the two groups ( Z=-0.97, -1.12, -0.98, P>0.05). Conclusion:Minimally invasive liver resection or even major liver resection is safe and feasible for screened HCC patients complicated with portal hyper-tension, but attention should be paid to the prevention and treatment of postoperative complications.

The acute combination fractures of the atlas and axis in adults have a higher rate of neurological injury and early death compared with atlas or axial fractures alone. Currently, the diagnosis and treatment choices of acute combination fractures of the atlas and axis in adults are controversial because of the lack of standards for implementation. Non-operative treatments have a high incidence of bone nonunion and complications, while surgeries may easily lead to the injury of the vertebral artery, spinal cord and nerve root. At present, there are no evidence-based Chinese guidelines for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults. To provide orthopedic surgeons with the most up-to-date and effective information in treating acute combination fractures of the atlas and axis in adults, the Spinal Trauma Group of Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field of spinal trauma to develop the Evidence-based guideline for clinical diagnosis and treatment of acute combination fractures of the atlas and axis in adults ( version 2023) by referring to the "Management of acute combination fractures of the atlas and axis in adults" published by American Association of Neurological Surgeons (AANS)/Congress of Neurological Surgeons (CNS) in 2013 and the relevant Chinese and English literatures. Ten recommendations were made concerning the radiological diagnosis, stability judgment, treatment rules, treatment options and complications based on medical evidence, aiming to provide a reference for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults.

Purpose: Neutrophil-to-lymphocyte ratio (NLR) has been reported to predict adverse survival outcomes among patients with colorectal cancer (CRC). This study evaluates the prognostic value of NLR among patients with obstructing CRC who successfully underwent stenting before curative surgery. Methods: We retrospectively reviewed patients who underwent stenting before surgery. Patient demographics, tumor characteristics, perioperative outcomes, recurrence-free survival (RFS), and overall survival (OS) were analyzed. NLR was calculated from the differential white blood cell counts at least 4 days after successful stenting, before elective surgery. Optimal cutoff to dichotomize NLR was obtained by maximizing log-rank test statistic with recursive partitioning of KaplanMeier RFS and OS curves. The optimal cutoff for high NLR was ≥ 5 at presentation before stenting, and ≥ 4 after stenting. Results: Fifty-seven patients with localized obstructing CRC underwent successful endoscopic stenting before curative surgery. High NLR was associated with lymphovascular invasion (P = 0.006) and apical lymph node involvement (P = 0.034). Major perioperative complication(s) (hazard ratio [HR], 11.34; 95% confidence interval [CI], 2.49 to 51.56; P < 0.01) and high NLR (HR, 3.69; 95% CI, 1.46 to 9.35; P < 0.01) negatively impacted OS on univariate and multivariate analyses. High NLR negatively impacted RFS on univariate analysis (HR, 2.91; 95% CI, 1.29 to 6.60; P = 0.01). Conclusion NLR of ≥ 4 after stenting is an independent prognostic factor among patients with obstructing localized CRC who are successfully decompressed by endoscopic stenting before curative surgery.
