Objective: To examine the relationship between self-management behaviors and time perspective among patients with comorbid diabetes, so as to provide the evidence for improving self-management behaviors among patients with comorbid diabetes. Methods: The patients with comorbid diabetes who were registered in the chronic disease health management system of Minhang District, Shanghai Municipality in 2021, followed up regularly, and lived in Meilong Town were recruited. Demographic information and family history of diabetes were collected through questionnaire surveys. Time perspective and self-management behaviors were assessed using the Zimbardo Time Perspective Inventory and Diabetes Self-Management Behavior Scale, respectively. The relationship between self-management behaviors and time perspective was analyzed using a multivariable ordinal logistic regression model. Results: A total of 907 patients with comorbid diabetes were enrolled, including 472 males (52.04%) and 435 females (47.96%). There were 652 cases aged 65 years and above, accounting for 71.89%. In terms of the types of time perspective, 280 patients were future-oriented (30.87%), 236 were balanced (26.02%), 162 were sensation-seeking (17.86%), 123 were fatalistic (13.56%), and 106 were negative (11.69%). In terms of the self-management behaviors, 46 patients were good (5.07%), 643 were moderate (70.89%), and 218 were poor (24.04%). Multivariable ordinal logistic regression analysis showed that after adjusting for age, gender, educational level, marital status, occupation status, monthly income, and family history of diabetes, the patients with comorbid diabetes who had a future-oriented time perspective had better self-management behaviors (OR=1.874, 95%CI: 1.204-2.915). Conclusion The self-management behaviors among patients with comorbid diabetes are moderate to poor, and patients with a future-oriented time perspective can better engage in self-management behaviors.

ObjectiveTo investigate the safety and efficacy of puncture cyanoacrylate selective seal （PCSS） under endoscopic ultrasound in the treatment of gastroesophageal varices （GOV）. MethodsA total of 100 patients with liver cirrhosis who underwent endoscopic therapy for the secondary prevention of GOV bleeding in Beijing Ditan Hospital， Capital Medical University， from March 1 to December 31， 2023 were enrolled and randomly divided into PCSS group and traditional endoscopy group. The patients were followed up for 6 months after surgery， and the two groups were compared in terms of clinical outcome and complications. The primary outcome measure was the rate of alleviation or disappearance of GOV， and the secondary outcome measure was variceal rebleeding and death. The independent-samples t test was used for comparison of normally distributed or approximately normally distributed quantitative data between two groups， and the Wilcoxon non-parametric test was used for comparison of non-normally distributed quantitative data between two groups； the chi-square test or the Fisher’s exact test was used for comparison of qualitative data between two groups. ResultsThere were 50 patients in the PCSS group， among whom 1 patient was lost to follow-up， and there were 50 patients in the traditional endoscopy group， among whom 3 patients were lost to follow-up. There were no significant differences between the two groups in baseline data such as age， sex， Child-Pugh class， varices grade， and GOV typing （all P>0.05）. Compared with the traditional endoscopy group， the PCSS group had significantly better results of the number of endoscopic treatment sessions （t=-15.671， P=0.001）， the total amount of tissue adhesive used （t=-2.830， P=0.006）， and the rate of alleviation or eradication of varices sclerosis （χ²=7.078， P=0.029）. Both groups had low rates of postoperative rebleeding， adverse reactions， and complications， and there were no significant differences between the two groups （all P>0.05）. ConclusionCompared with traditional endoscopy， PCSS can significantly enhance treatment outcome while maintaining safety standards.

Objective: To investigate the trajectories of fasting blood glucose fluctuations and their influencing factors among patients with comorbidity of type 2 diabetes mellitus (T2DM), so as to provide the basis for strengthening blood glucose management in this population. Methods: In October 2023, data of patients diagnosed with comorbid T2DM from January to October 2021, including demographic information, lifestyle, health status and fasting blood glucose were collected through the chronic disease health management system of Minhang District, Shanghai Municipality. Fasting blood glucose fluctuation trajectories were analyzed by group-based trajectory model established based on fasting blood glucose values from January 2021 to October 2023. Influencing factors of fasting blood glucose fluctuation trajectories among patients with comorbidity of T2DM were analyzed using a multinomial logistic regression model. Results: A total of 907 patients with comorbidity of T2DM were enrolled, including 472 males (52.04%) and 435 females (47.96%). There were 652 cases aged ≥65 years, accounting for 71.89%. The group-based trajectory model analysis identified three trajectory groups: a low-level stable group (492 cases, 54.24%), a medium-level stable group (287 cases, 31.64%), and a high-level decreasing group (128 cases, 14.11%). Multinomial logistic regression analysis showed that, compared with the low-level stable group, patients with comorbidity of T2DM who had an education level of junior high school or below (OR=1.420, 95%CI: 1.011-1.995) or college degree or above (OR=2.109, 95%CI: 1.249-3.560), as well as those who engaged in regular exercise (OR=1.387, 95%CI: 1.017-1.893), were more likely to be in the medium-level stable group. Patients with comorbidity of T2DM who were overweight or obese (OR=1.675, 95%CI: 1.116-2.513) or had dyslipidemia (OR=3.195, 95%CI: 1.642-6.216) were more likely to be in the high-level decreasing group. Conclusions From January 2021 to October 2023, the fasting blood glucose levels of patients with comorbidity of T2DM exhibited three fluctuating trajectories: low-level stability, medium-level stability, and high-level decline. Compared with the low-level stable group, the medium-level stable group was mainly influenced by educational level and regular exercise. The high-level decline group was primarily affected by overweight/obesity and dyslipidemia.

Objective: To investigate the trend in disease burden of injuries among children and adolescents in China from 1990 to 2021, so as to provide a basis for formulating prevention and control strategies and reducing this disease burden. Methods: Data on mortality, disability-adjusted life years (DALY) rate, incidence, and prevalence of injuries among children and adolescents aged <20 years in China from 1990 to 2021 were collected from the Global Burden of Disease (GBD) 2021 database. All rates were standardized using the GBD 2021 world standard population. The trend in incidence of disease burden of injuries among children and adolescents across differents genders and ages from 1990 to 2021 was evaluated using average annual percent change (AAPC). Results: From 1990 to 2021, the standardized mortality (AAPC=-5.435%), standardized DALY rate (AAPC=-5.311%), standardized incidence (AAPC=-0.466%), and standardized prevalence (AAPC=-0.810%) of injuries among children and adolescents in China showed downward trends (all P<0.05). Among these, the standardized mortality of animal contact (AAPC=-9.138%) and the standardized DALY rate of medical side effects (AAPC=-8.389%) decreased at a relatively fast pace, while the standardized incidence of falls (AAPC=0.083%) and the standardized prevalence of exposure to natural forces (AAPC=2.656%) showed upward trends (all P<0.05). The standardized mortality, standardized DALY rate, standardized incidence and standardized prevalence of injuries were higher in males than in females. The trend in males showed a downward trend (all P<0.05), consistent with the total population. The crude incidence of injuries in the group aged 15-<20 years showed an upward trend (AAPC=0.391%, P<0.05), while the trend in the group aged 10-<15 years was not statistically significant (P>0.05). The crude incidence of injuries in the groups aged 5-<10 years and <5 years showed downward trends (AAPC=-0.488% and -2.275%, both P<0.05). In 2021, the <5 years age group had the highest crude mortality and crude DALY rate of injuries, at 13.94/100 000 and 1 257.26/100 000, respectively. The 15-<20 years age group exhibited the highest crude incidence and crude prevalence, at 4 874.05/100 000and 4 050.35/100 000, respectively. Drowning and falls were major components of the disease burden across all age groups. Conclusions From 1990 to 2021, the disease burden of injuries among children and adolescents in China showed an overall downward trend. The disease burden was consistently higher in males than in females. Children aged <5 years face a high risk of fatality and disability, while adolescents aged 15-<20 years experience a high incidence and frequency of injuries. Drowning and falls were key priorities for prevention and control.

Objective:To assess the efficacy of different fusion strategies involving the convolutional block attention module (CBAM) and Unet for automatic pancreas segmentation in enhanced CT images of patients with acute pancreatitis.Methods:A retrospective analysis was conducted on 1 158 patients with acute pancreatitis admitted to the Affiliated Hospital of North Sichuan Medical College between January 1st, 2016 and July 30th, 2021. Among them, 141 patients with first-episode acute pancreatitis were randomly categorized into mild, moderate, and severe cases. The test set comprised 5 mild and 15 severe cases, while the remaining 126 cases were used for training. Within the training set, 20% of the data was randomly allocated as the validation set. Different fusion paths of the CBAM and Unet networks were trained, utilizing the Dice similarity coefficient, Hausdorff distance (HD), and pixel accuracy (PA) as evaluation metrics. The model demonstrating the best performance on the validation set was selected and evaluated on the test set. Additionally, the Unet model was combined with the attention gate attention mechanism (AttentionUnet) in the skip connection, and the ResBlock replaced the original convolution module (ResUnet) in the Unet network. Moreover, the skip connection branch module of feature extraction was integrated with CBAM (ResUnet_CBAM) for comparison.Results:Unet_CBAM achieved better results on the test set with a Dice value of 80.06%, a HD value of 3.765 9 and a PA value of 0.992 3, all surpassing other fusion strategies. The segmentation accuracy of the pancreatic region in CT images of acute pancreatitis patients was notably enhanced compared to Unet and its related variant networks.Conclusions:The Unet network integrated into CBAM after skip connection can better perform pancreatic segmentation on enhanced CT images of patients with acute pancreatitis and can effectively improve the efficiency of relevant personnel in pancreatic segmentation on enhanced CT images of patients with acute pancreatitis.

Objective:To systematically evaluate the prevalence of malnutrition in elderly patients with diabetes.Methods:A total of eight databases, namely PubMed, Embase, Web of Science, The Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang Database, Chinese Biomedical Literature Database (CBM), and VIP Database, were systematically searched for cross-sectional studies on malnutrition in elderly diabetic patients published from the inception of the databases to September 13, 2023. Two researchers independently conducted literature screening, data extraction, and quality assessment. Data analysis was performed using Stata 16.0 software.Results:A total of 22 studies were included, involving 6 349 elderly diabetic patients. Results of the meta-analysis showed that the overall prevalence of malnutrition in elderly patients with diabetes was 32.3% (95% CI: 0.21 to 0.43), and the prevalence of at-risk of malnutrition was 49.0% (95% CI: 0.31 to 0.67). Subgroup analysis showed that the prevalence of malnutrition in elderly diabetic patients with chronic complications (56.8%) was significantly higher than those without chronic complications (21.9%). Inpatients also showed a higher prevalence compared with outpatients and community (44.4%, 29.0%, and 18.5%, respectively). The prevalence of malnutrition as per mini-nutritional assessment scale was higher than that as per mini-nutritional assessment short-form scale (35.8% vs. 23.3%, P<0.05). There was no significant difference in the prevalence of malnutrition in elderly diabetic patients of different genders ( P>0.05). Conclusions:The prevalence of malnutrition and at-risk of malnutrition in elderly diabetic patients is high. In clinical practice, we should not only strengthen the early diagnosis of malnutrition in patients, but also emphasize the screening of malnutrition risk, implement timely corresponding interventions, and promote patient education on nutrition and health, to improve the prognosis and quality of life in elderly diabetes patients.

Objective To investigate the effect of resistant starch(RS)on the intestinal microbiota and metabolism in obese rats with type 2 diabetes mellitus(T2DM).Methods The Wistar rats were divided into normal control(NC)group,model group(Mod),acarbose intervention group(Aca)and RS intervention group(RS),with 8 rats in each group.TC,TG,HDL-C,and LDL-C were detected after 8 weeks of continuous administration.Lee's index,insulin sensitivity index(HOMA-IS),insulin resistance index(HOMA-IR),pancreatic β cell function index(HOMA-β),inflammatory factors,and area under the curve of glucose tolerance(AUC)were calculated.Serum TNF-α,IL-6 and lipopolysaccharide(LPS)were detected by ELISA.The steatosis of liver tissue was observed by HE staining,and the feces were collected for 16S rDNA sequencing in each group.Species difference analysis,Beta diversity analysis and other methods were used to analyze the structure and quantity of intestinal microbiota.Results The Lee's index was higher in the Mod,Aca and RS groups than in the NC group(P<0.05).Compared with the NC group,TC,TG,LDL-C,HDL-C,FIns,HOMA-IR,TNF-α,IL-6 and LPS were increased(P<0.05),HOMA-β and HOMA-IS decreased in the Mod,Aca,and RS groups(P<0.05).Compared with the Mod group,TC,TG,LDL-C,HDL-C,FIns,HOMA-IR,TNF-α,IL-6 and LPS decreased(P<0.05),and HOMA-IS and HOMA-β increased in the Aca and RS groups(P<0.05).Compared with the Aca group,IL-6 was increased(P<0.05),and LDL-C and HDL-C decreased in the RS group(P<0.05).The results of 16S rDNA sequencing showed that the total number of operational taxonomic units were increased and the diversity and uniformity of the intestinal microbiota were also increased in the Aca and RS groups.Conclusions RS can regulate glucose and lipid metabolism,improve IR,increase intestinal microbial diversity,regulate intestinal microbiota structure,and maintain intestinal health in obese rats with T2DM.

Objective:To explore the effectiveness of body weight support in gait training after surgery for an ankle fracture.Methods:Thirty-eight ankle fracture patients who received surgery were divided at random into an observation group and a control group, each of 19. In addition to 3 sessions of routine gait rehabilitation training a week for 6 weeks, only those in the observation group received body weight support training with body weight support boots. Gait data were collected using the GaitWatch three-dimensional gait action capture and training system before the training and after 2, 4 and 6 weeks of the training.Results:At each assessment the gait frequency, gait cycle, stride length, stride rate, bilateral step length, step length deviation, bilateral support phase and bilateral swing phase of both groups had improved significantly. After 6 weeks the average stride frequency, gait cycle, stride length on both sides and speed of the observation group had improved significantly more than among the control group. Step length deviation was not significantly different, however. At each evaluation the proportions of affected and healthy side support had decreased significantly in both groups, but affected and healthy side swing had increased and the proportion of bilateral support had decreased significantly.Conclusion:Body weight support training with body weight support boots can significantly improve gait after ankle fracture surgery. Its effect is superior to that of conventional gait training.

Objective To evaluate the change of cardiac structure and function in patients with hypertrophic obstructive cardiomyopathy(HOCM)after ultrasound-guided percutaneous intramyocardial septal radiofrequency ablation(PIMSRA)via cardiac magnetic resonance(CMR).Methods Patients with HOCM who underwent PIMSRA,echocardiography and CMR preoperative scanning and one year after surgery were analyzed retrospectively.Myocardial structural and functional parameters were measured by Circle cardiovascular imaging post-processing software.The changes of myocardial parameters before and after surgery were compared by using paired sample t-test and Chi-square test.Results Compared with the preoperative assessment,patients'clinical symptoms and the cardiac function were significantly improved one year after surgery.The left ventricular outflow tract pressure gradient(LVOT-PG)was significantly decreased and length of mitral regurgitation was shortened one year after surgery compared with before surgery via ultrasound(P<0.05).Compared with the preoperative assessment,CMR showed that patients with end-systolic volume of left atrium,minimum volume of left atrium,transverse diameter of left atrium,thickness of ventricular septum and free wall of left ventricular at end-systolic section were significantly reduced,and left ventricular mass(LVM)was significantly decreased one year after surgery,with statistical significance between before and after surgery(P<0.001).One year after surgery,the left atrium ejection fraction(LAEF)was significantly increased(P<0.05),the maximum slope and the maximum signal intensity of the ventricular septum and the left ventricular free wall of the papillary muscle were significantly increased(P<0.001),and the peak time was significantly decreased(P<0.001)compared with before surgery.Conclusion After PIMSRA treatment,the systolic function of left atrium in HOCM patients is improved,and the microcirculation perfusion of left ventricular is significantly improved.

Objective To understand the genotyping of human immunodeficiency virus (HIV) co-infected hepatitis C virus (HCV) patients in Yunnan Province, and to analyze the differences in viral load, biochemical indicators, and blood routine indicators among different genotypes, in order to provide a laboratory basis for the diagnosis and clinical treatment of HIV/HCV co-infected patients. Methods From November 2022 to June 2023, the serum samples and basic information of patients diagnosed with HIV/HCV co-infection were collected in the antiviral outpatient clinic of Yunnan Provincial Hospital of Infectious Diseases. The HCV viral load was detected by one-step qRT-PCR amplification, the positive samples were sequenced, and genotyping was determined based on NS5 gene sequence. The differences in biochemical and blood routine indexes between HIV patients co-infected with different HCV genotypes and low/high viral loads were analyzed. Results A total of 126 HIV/HCV co-infected patients were collected, including 20 HCV genotype 1 (15.9%), 91 HCV genotype 3 (72.2%), and 15 HCV genotype 6 (11.9%). The maximum and minimum viral load of the three HCV genotypes were as follows: HCV type 1 (1.0×108, 4.8×104 IU/mL), HCV type 3 (2.2×108, 2.9×102 IU/mL), and HCV type 6 (8.1×107, 6.8×104 IU/mL). The results showed that there was no significant difference between HIV co-infection with different genotypes of HCV and three HIV treatment schemes, including nucleoside reverse transcriptase inhibitors+integrase strand transfer inhibitors (NRTIs+INSTIs), nucleoside reverse transcriptase inhibitors+non-nucleoside reverse transcriptase inhibitors (NRTIs+NNRTIs) and nucleoside reverse transcriptase inhibitors+protease inhibitor (NRTIs+PLs), and the viral load of patients (P>0.05). The analysis of biochemical indexes such as total bilirubin (TBIL), direct bilirubin (DBIL), alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine (CREA), and blood routine indexes such as white blood cell (WBC), red blood cell (RBC), hemoglobin (HGB), platelet (PLT), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) among different HCV genotypes and low/high viral loads showed that there was no significant difference in biochemical indexes and blood routine indexes between low/high viral loads of HIV co-infected HCV patients (P>0.05); however, the biochemical indicators TBIL, IBIL and MCHC were significantly different statistically between patients with genotype 3 HCV infection and those with genotype 1 HCV infection (P<0.05), while other biochemical and blood routine indexes were not statistically different among different HCV genotypes (P>0.05). Conclusions There are six subtypes of HCV co-infection in HIV patients in Kunming, Yunnan Province, including three genes of genotype 1, 3, and 6. Among them, genotype 3 HCV is the main prevalent genetic virus among HIV co-infected populations. The TBIL, IBIL and MCHC values of HIV patients co-infected with HCV type 3 are different from those infected with HCV type 1.
