The importance of gait assessment in the rehabilitation of cancer patients is gradually being recognized. However, quantitative analysis of balance ability in cancer patients is still limited. A total of 102 cancer patients meeting the inclusion criteria were recruited from Hefei Cancer Hospital, Chinese Academy of Sciences. Their balance ability was evaluated using the Berg Balance Scale (BBS). Gait data were collected by an electronic walkway and an IMU sensor system, including spatial-temporal and kinematic gait features such as step length, cadence, support time, and range of motion. Recursive feature elimination was used for feature selection. Ridge, Elastic Net, SVR, RF, and AdaBoost models were used to predict balance ability scores. Five-fold cross-validation was used to evaluate the performance of these models. Results show that the SVR model achieves the best performance with fifteen features (RMSE=3.22, R ²=0.91), followed by Ridge (RMSE=3.63, R ²=0.89). A method for evaluating balance ability based on gait features is proposed, providing a quantitative tool for personalized rehabilitation interventions in cancer patients.

Objective:To analyze the correlation between gastric disharmony and daily eating behaviors in college students, and to provide intervention measures for improving gastric disharmony among college students.Methods:From April 10 to 30, 2021, 3 825 college students from five Chinese medicine colleges and universities in China were selected for this study using the multi-level sampling method. The information regarding college student's general situation, daily eating behavior, and stomach disharmony was collected by questionnaire.Results:A total of 3 700 valid questionnaires were collected, with an effective response rate of 96.73%. The average age was (20.0 ± 3.0) years, and 66.41% of college students included in this study were female. Students with different characteristics had different gastric disharmonies and eating behaviors, and gastric disharmony was correlated with eating behavior. Multivariate analysis results showed that snacking ( OR = 1.11, 95% CI: 1.02-1.21), partial eclipse ( OR = 1.12, 95% CI: 1.00-1.26), picky eaters ( OR = 1.23, 95% CI: 1.08-1.41), and supper ( OR = 1.19, 95% CI: 1.04-1.36) were positively correlated with gastric disharmony. Eating regular meals ( OR = 0.86, 95% CI: 0.79-0.94) and 80% fullness ( OR = 0.89, 95% CI: 0.81-0.98) were negatively correlated with gastric disharmony. Conclusion:Poor eating behaviors may be an important factor leading to gastric disharmony.

Objective:To analyze the prognostic risk factors of patients with sepsis and the clinical characteristics of patients with septic myocardial injury.Methods:A retrospective study was conducted. The clinical data of 300 patients with sepsis admitted to emergency department of Zhongshan Hospital of Fudan University from September 2017 to June 2020 were enrolled, including basic information, blood test indicators and auxiliary inspection indicators. The patients were grouped according to myocardial injury and the clinical characteristics of patients with septic myocardial injury were analyzed. According to 28-day prognosis, they were divided into survival group and non-survival group. The differences in various indicators between the two groups were compared, and binary Logistic regression was used to explore independent risk factors for death in patients with sepsis.Results:In 300 patients, 47 patients were excluded for previous heart disease or lack of the main inspections, and 253 patients were enrolled finally. ① Myocardial injury occurred in 136 out of 253 patients (53.8%), and 117 without myocardial injury. Compared with the non-myocardial injury group, the myocardial injury group had higher blood white blood cell count [WBC (×10 9/L): 9.7 (6.7, 13.4) vs. 8.3 (5.4, 12.2)] and procalcitonin [PCT (μg/L): 0.61 (0.18, 4.63) vs. 0.23 (0.09, 0.99)] at admission, and more Staphylococcal infections (17.6% vs. 2.6%), more arrhythmia (sinus tachycardia: 30.9% vs. 23.1%), more ST-T changes (26.5% vs. 23.1%), lower left ventricular ejection fraction [LVEF: 0.60 (0.54, 0.65) vs. 0.62 (0.60, 0.66)], higher pulmonary artery systolic pressure [PASP (mmHg, 1 mmHg = 0.133 kPa): 38.0 (32.2, 46.0) vs. 33.0 (30.0, 40.2)], and worse prognosis (28-day mortality: 44.1% vs. 6.0%, all P < 0.05). Logistic regression analysis showed that PCT increased [odds ratio ( OR) = 1.039, 95% confidence interval (95% CI) was 1.018-1.060, P < 0.01], LVEF decreased ( OR = 0.828, 95% CI was 0.729-0.941, P < 0.01) and sinus tachycardia ( OR = 3.512, 95% CI was 1.417-8.702, P < 0.01) were clinical characteristics of septic patients with myocardial injury. ② A total of 186 of the 253 patients survived, and 67 died with 28-day mortality of 26.5%. Compared with the survival group, non-survival group had higher myocardial markers and inflammation markers at admission [cardiac troponin T (cTnT, μg/L): 0.06 (0.02, 0.17) vs. 0.02 (0.01, 0.05), N-terminal pro-brain natriuretic peptide (NT-proBNP, ng/L): 3 037.0 (1 308.7, 12 033.7) vs. 893.9 (272.8, 2 825.5), creatine kinase (CK, U/L): 144.5 (57.5, 660.8) vs. 89.5 (47.8, 201.0), WBC (×10 9/L): 10.5 (6.7, 14.6) vs. 8.6 (6.0, 12.0), C-reactive protein (CRP, mg/L): 89.2 (54.8, 128.5) vs. 63.8 (19.3, 105.6), PCT (μg/L): 2.13 (0.31, 11.79) vs. 0.28 (0.10, 1.25), all P < 0.05], and more sinus tachycardia and atrial arrhythmia (41.8% vs. 22.0%, 29.9% vs. 17.7%, both P < 0.05). Logistic regression analysis showed that cTnT increased ( OR = 2.115, 95% CI was 1.189-5.459, P < 0.05), sinus tachycardia ( OR = 2.557, 95% CI was 1.103-5.929, P < 0.05) and atrial arrhythmia ( OR = 2.474, 95% CI was 1.025-5.969, P < 0.05) were independent risk factors for 28-day death in patients with sepsis. Conclusions:Myocardial injury is an independent risk factor for death in patients with sepsis. PCT elevation, LVEF decreased and sinus tachycardia are main characteristics of patients with septic myocardial injury, which should attract clinical attention.

Guangdong province is experimenting with a model composed of various types of medical alliances, having achieved initial success with some of them and preliminarily has formed a holistic governance pattern. Experiences behind such initial success lied in a coordinated top-level design, reasonable and classified guidance, leader role of key governance subjects, and the construction of a telemedical system. However, as analyzed from the angle of collaborative governance, existing medical alliances have not yet formed a community of services, that of responsibility, that of interests, and that of services. In this consideration, the authors recommended to strengthen the collaborative governance of such alliances by respective governance subjects based on the theories of integrated medical service system and collaborative governance, eventually forming an integrated medical and health service system.

Objective:To compare the predictive value of the HEART, TIMI and GRACE scores for major adversecardiovascular events (MACEs) at 7 and 28 days in patients with actue non-ST-segment elevation myocardial infarction (NSTEMI).Methods:More than 12 000 patients with chest pain from the Emergency Department of Zhongshan Hospital Affiliated to Fudan University from October 2017 to October 2018 were studied, including 566 patients with cardiogenic chest pain, 105 patients with ST-segment elevation myocardial infarction (STEMI) excluded and 15 patients lost to follow-up. Finally, 109 patients with NSTEMI and 337 non-myocardial patients with cardiogenic chest pain were enrolled. NSTEMI patients were divided into subgroups according to whether MACEs occurred. LSD t-test, Mann-Whitney U test or χ2 test were used to analyze and compare the differences between the two subgroups about the baseline data, clinical data, HEART, TIMI and GRACE scores at the time of visit. Multivariate logistic regression analysis was used to explore the independent factors of MACEs at 7 and 28 days. And the predictive values of different scores for 7-day MACEs and 28-day MACEs were compared in NSTEMI patients through the receiver operating characteristic (ROC) curve. Results:Compared NSTEMI patients with non-myocardial patients with cardiogenic chest pain, we found a statistically significant differences in sex, past history of coronary heart disease,≥3 risk factors for atherosclerosis, electrocardiogram, high-sensitivity troponin T (hs-cTnT), creatinine value, past history of myocardial infarction, HEART score, TIMI score and GRACE score. In further subgroup analysis of NSTEMI patients who were divided according to whether MACEs occurred, we found previous history of stroke and increased hs-cTnT were statistically different in 7 days after the onset of the disease. The multivariate analysis showed that the previous history of stroke and increased hs-cTnT were independent factors for the occurrence of MACEs at 7 days after the onset of NSTEMI; The previous history of stroke and increased hs-cTnT, electrocardiogram ST segment depression and TIMI score were statistically different at 28 days after the onset of NSTEMI. The multivariate analysis showed that the previous history of stroke and TIMI score were independent factors for the occurrence of MACEs at 28 days after the onset of NSTEMI patients. ROC curve indicated that the predictive value of TIMI score (AUC=0.715, 95% CI: 0.482-0.948) was better than HEART (AUC=0.659, 95% CI: 0.414-0.904) and GRACE scores (AUC=0.587, 95% CI: 0.341-0.833)in predicting MACEs in NSTEMI patients. Conclusions:HEART score, TIMI score and GRACE score can be used to evaluate NSTEMI patients. There is an independent predictive value on TIMI score for the occurrence of 28-day MACEs in NSTEMI patients.

Objective: To systematically review the quality and reporting quality of colorectal cancer screening guidelines, and to provide reference for the update of colorectal cancer screening guidelines and colorectal cancer screening in China. Methods: "Colorectal cancer", "colorectal tumor", "screening", "screening", "guide", "consensus", "Colorectal cancer", "Colorectal neoplasms", "Screening", "Early Detection of Cancer", "Guideline" and "recommendation" were used as search keywords. The literature retrieval for all the Chinese and English guidelines published before April 2018 was conducted by using PubMed, Embase, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang Data, China Biology Medicine disc (CBMdisc), Cochrane Library, Guideline International Network, China Guidelines Clearinghouse (CGC) and the official website of the US Preventive Services Task Force (USPSTF), the American Cancer Society (ACS), International Agency for Research on Cancer (IARC), Australia Cancer Council (ACC) and Association of Coloproctology of Great Britain & Ireland (ACPGBI). The inclusion criteria were independent guidance documents for colorectal cancer screening. The language is limited to Chinese and English. The exclusion criteria were literature on interpretation, evaluation, introduction, etc., as well as the translated version of the guide and old guides. The quality and reporting norms of colorectal cancer screening guidelines were compared and evaluated using the European Guideline Research and Assessment Tool (AGREE Ⅱ) and the Practice Guideline Reporting Standard (RIGHT). Results: A total of 15 guides were included. The results of the AGREE Ⅱ quality evaluation showed that the overall quality of 15 guides was high. Among them, there were 9 guides with an overall score of 50 or more, 10 with a recommendation level of "A", and 2 with a rating of "B". There were 3 guides for "C"; each guide scores higher in scope and purpose, and clarity, and scores vary greatly in the areas of participants, rigor, applicability, and independence. The results of the RIGHT evaluation showed that 15 guides were insufficient in six areas except for background information, evidence, recommendations, reviews and quality assurance, funding and conflict of interest statements and management, and other aspects. Conclusion The overall quality of included guidelines for colorectal cancer screening is high, but the normative nature needs to be strengthened.

Hepatocellular carcinoma (HCC) is the major histological type of primary liver cancer (PLC), and the etiology is relative clear. Chronic infection of hepatitis B virus (HBV) plays dominant roles, and high exposure to aflatoxins is an important co-factor. Qidong was one of the endemic area with high PLC incidence in rural China. The results from a series of etiological intervention studies on PLC in this area indicated that 1) the protective efficacy of neonatal HBV vaccination against PLC development under the age of 30 was 84% (95% CI 23%-97%); 2) the relative risk of liver cancer incidence decreased at least 4 folds in young adults aged <35 years with reducing aflatoxin exposures and cleaning drinking water. The prevention of HBV infection and the supplies of clean water and safe food with limited aflatoxins demonstrated as an effective primary prevention model of liver cancer in rural China.
