Objective To investigate the status quo of health management behaviors in elderly patients with type 2 diabetes mellitus(T2DM)complicating chronic complications and the influencing factors based on health ecology theory.Methods The convenience sampling method was used to select elderly patients with T2DM complicating chronic complications in the Shanghai City from January to July 2022 as the respondents.Based on the health ecology theory,the five aspects of personality traits,psychological and behavioral traits,family and community interpersonal networks,living and working conditions and policy environment were in-vestigated.The Pearson correlation coefficient was used to analyze the correlation of various variables.The hi-erarchical linear regression was used to analyze the influencing factors of health management behaviors in eld-erly patients with T2DM complicating chronic complications.Results A total of 272 questionnaires were dis-tributed and 264 valid questionnaires were recovered,with an effective recovery rate of 97.06％(264/272).There were statistically significant differences in DSMB-Oscores among the patients with different chronic complications number,sleep quality,per capita monthly household income and medical payment methods(P＜0.05).The DSMB-Oscore in elderly patients with T2DM complicating chronic complications was positively correlated with HLSCP,DES,PACIC and CIRS scores(P＜0.05),and negatively correlated with the PAID-5 score(P＜0.05).Conclusion The health management behaviors of elderly patients with T2DM complicating chronic complications is jointly affected and acted by many factors,and it is necessary to identify and manage the related influencing factors from different aspects and different levels.

Cannabidiol (CBD), a non-psychoactive cannabinoid, shows great promise in treating methamphetamine (METH) addiction. Nonetheless, the molecular target and the mechanism through which CBD treats METH addiction remain unexplored. Herein, CBD was shown to counteract METH-induced locomotor sensitization and conditioned place preference. Additionally, CBD mitigated the adverse effects of METH, such as cristae loss, a decline in ATP content, and a reduction in membrane potential. Employing an activity-based protein profiling approach, a target fishing strategy was used to uncover CBD's direct target. ATP5A1, a subunit of ATP synthase, was identified and validated as a CBD target. Moreover, CBD demonstrated the ability to ameliorate METH-induced ubiquitination of ATP5A1 via the D376 residue, thereby reversing the METH-induced reduction of ATP5A1 and promoting the assembly of ATP synthase. Pharmacological inhibition of the ATP efflux channel pannexin 1, blockade of ATP hydrolysis by a CD39 inhibitor, and blocking the adenosine A1 receptor (A1R) all attenuated the therapeutic benefits of CBD in mitigating METH-induced behavioral sensitization and CPP. Moreover, the RNA interference of ATP5A1 in the ventral tegmental area resulted in the reversal of CBD's therapeutic efficacy against METH addiction. Collectively, these data show that ATP5A1 is a target for CBD to inhibit METH-induced addiction behaviors through the ADO-A1R signaling pathway.

Objective To investigate the needs of the main caregivers of patients with spinal cord injury following neurogenic bowel dysfunction to participate in the whole process of intestinal management.Methods Nine main caregivers of patients with spinal cord injury in Jiangsu Province Hospital from January to Decem-ber,2024 were selected with objective sampling method.They were investigated face-to-face semi-structured in-depth interviews,and the data were analyzed,summarized and extracted by Colaizzi 7-step analysis method.Results Three themes and eight sub-themes were extracted:the needs of professional knowledge and skills standards in intestinal management(lack of intestinal training knowledge,lack of ability to acquire knowledge and different standards of medical institutions);the needs of physical ability and decision making ability participating in intesti-nal training(lack of participation,single decision-making behavior,excessive dependence on medical personnel);the desire for therapeutic benefits and the needs for building psychological confidence(concerns about the pa-tient's prognosis,overdependence on medication).Conclusion Clinical medical staff should pay attention to the actual needs and difficulties faced by the main caregivers of patients with neurogenic bowel dysfunction to participate in the entire intestinal management,and construct targeted training programs,strengthen the skills and knowledge training,to enhance their autonomy and responsi-bility,to achieve the rehabilitation goal better.

Objective:To explore the pathway of influencing factors of self-management in elderly patients with type 2 diabetes mellitus (T2DM) based on health belief theory.Methods:It was a cross-sectional study. A total of 210 elderly patients with T2DM admitted to Shanghai 10th People′s Hospital from January 2021 to March 2022 were selected as research subjects.The surveys of general data questionnaire, social support rating scale, the diabetes self-management scale, the health literacy survey scale for patients with chronic diseases, and the self-efficacy scale for patients with diabetes were conducted in all the subjects. The t test and Spearman correlation analysis were used to test the correlation among variables. Results:Social support, health literacy and self-efficacy were positively correlated with self-management scores in these patients ( r=0.380, 0.392, 0.274, all P<0.001). Univariate analysis showed that there were statistically significant differences in self-management among patients with different age, education level, physical exercise, medical payment method, family history and sleep quality (all P<0.05). Path analysis showed that the mediating effect of social support in the relationship between health literacy and self-efficacy was significant (95% CI: 0.014-0.117), social support, self-efficacy and health literacy directly affected self-management( β=0.25, 0.27, 0.35, all P<0.01). Self-efficacy and health literacy also positively affected self-management through multiple mediators of social support ( β=0.16, 0.27, both P<0.01). Conclusion:Social support, self-efficacy and health literacy mediate in the self-management of elderly patients with T2DM complicated with chronic complications and interact with each other.

Objective: To survey on the home blood pressure measurement and blood pressure control rate among patients with hypertension in Beijing Yuetan community. Methods: A questionnaire survey was conducted among 504 hypertensive patients, who were visiting Beijing Yuetan Community Health Service Center and selected by convenience-sampling method during June 2018 to January 2019. The status of home blood pressure measurement, the awareness of hypertension, the blood pressure control rate and factors related to not regularly measuring were surveyed. Results: Of the 504 patients, 93.7% (472/504) took regular medication, but only 61.5% (310/504) had regular blood pressure measurements; 92.5% (466/504) had sphygmomanometers at home with electronic type mainly; 89.9% (453/504) patients knew the method of blood pressure measurement, but only 11.5% (52/453) had their sphygmomanometer calibrated. Among those who measured blood pressure, 77.4% (240/310) measured per week. The main reason for not measuring blood pressure regularly was that there was no need to measure blood pressure without any discomfort, accounting for 50.0% (97/194). The office blood pressure control rate (with desktop mercury sphygmomanometer) was 62.3% (314/504); the blood pressure control rate both in the morning and at bed time was 61.3% (73/119), that in the morning was 68.1% (81/119) and at bed time was 75.6% (90/119). The control rates of systolic blood pressure and heart rate by home measurement at morning and bedtime were significantly higher than those by office measurement (χ²=5.02, 9.97, 15.51, 13.72; all P<0.05). Conclusions The home blood pressure monitoring rate and knowledge level of hypertension among patients with hypertension in Yuetan community are relatively low. There are some differences in blood pressure control rate between office measurement and home measurement. Comprehensive evaluation is needed in the management process, and the treatment plan should be adjusted according to the specific condition of patients.

Objective To investigate the value of support vector machine based MRI-radiomics in the differential diagnosis of primary hepatic carcinomas (PHCs). Methods PHCs patients were retrospectively collected from July 2013 to February 2017 in the First Affiliated Hospital of Zhejiang University.All patients underwent unenhanced and enhanced MRI liver scan before surgery,and confirmed by pathology. A total of 294 PHCs patients (305 lesions), including 96 cases (97 lesions) of massive type cholangiocarcinoma (mCC), 107(107 lesions)of hepatocellular carcinoma (HCC), and 91 (101 lesions) of mixed hepatocellular and cholangiocellular carcinomas(HCC-CC).All patients underwent unenhanced and dynamic enhanced MRI liver scan including arterial, portal venous and equilibrium phases. Two hundred and three lesions (65 mCC, 71 HCC, 67 HCC-CC) were assigned into the training set, the remaining 102 lesions(32 mCC,36 HCC,34 HCC-CC)into the validation set,according to a ratio of 2:1.The entire lesions were delineated manually using a region of interest on equilibrium phase of enhanced MRI by using a home-made dedicated software(Analysis Kit,AK,General Electrics,US).Then the least absolute shrinkage and selection operator (LASSO) regression was used to select image features with a method of 10 fold cross-validation, and to reduce the dimensionality. The spearman method was used afterwards to condense the image features by removing redundant.A predictive model of diagnosing the different types of PHCs was established based on support vector machines(SVM),and the accuracy of applying the model in the data sets was used to evaluate the diagnostic efficacy of the model. Results A total of 280 quantitative imaging features were extracted in the training set.Thirty one imaging features were selected after LASSO regression and dimensionality reduction,and 21 features were remained after redundancy removing.The SVM showed the best generalization ability when the first 11 imaging features were used due to the Hughes effect.The 11 imaging features include 4 parameters of histogram,2 of textures,4 of gray-level co-occurrence matrix and 1 of gray-level run length matrix. A predictive model for PHCs was established after the study of the 11 imaging features and a regression analysis using SVM.The accuracy of the predictive model was 80.3% (163/203) in differentiating PHCs in the training set. The accuracy of the model was 75.5% (77/102) after applying it in the validation set. The diagnostic accuracy for HCC-CC, HCC and mCC was 85.3% (29/34), 77.8% (28/36) and 62.5% (20/32), respectively, in the validation set. For HCC-CC, 3 cases were misdiagnosed as mCC and 2 cases as HCC.For HCC,3 cases were misdiagnosed as HCC-CC and 5 cases as mCC.For mCC,9 cases were misdiagnosed as HCC-CC and 3 cases as HCC.The model showed the highest accuracy in predicting HCC-CC.Conclusion Radiomics method based on SVM may have a high accuracy in predicting different pathologic types of PHC,with the highest accuracy for HCC-CC.
