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.

Objective:To analyze and evaluate the equity of children's health in countries along the"the Belt and Road",promote further attention to children's health in countries along the route,and promote cooperation and exchanges on children's health between China and countries along the"the Belt and Road".Methods:Using concentration index and concentration curve to measure overall equity,and using the Thiel index for intraregional and interregional euqity measurement.Results:The under-five mortality concentration index is 0.349 7,the concentration curve is below the absolute fair line.The Thiel index shows that inequality in low-income countries,lower-middle-income countries,upper-middle-income countries and high-income countries is the leading cause of child health inequities in the"the Belt and Road"countries.Conclusion:There is inequity in the health of children in countries along"the Belt and Road Initiative",countries along the"the Belt and Road"should take comprehensive measures to reduce the under-five mortality rate,at the same time strengthen international cooperation to further promote equity in children's health in"Belt and Road"countries.

ObjectiveTo investigate the incidence of hypertension and its influencing factors in community-dwellers at risk for high blood pressure in Minhang District of Shanghai， and to provide scientific evidence for the community management. MethodsA retrospective cohort study was conducted using the electronic health records of community-dwellers at risk for high blood pressure in Minhang District， Shanghai from January 1， 2011 to December 31， 2017. The study end-point was the occurrence of hypertension，and the followup was finished in December 2021. A total of 17 265 community-dwellers at risk for high blood pressure were enrolled in our study. Log-rank test and Cox regression analysis were used to determine the influencing factors. ResultsAfter 6.04 years of follow-up， the hypertension incidence among community-dwellers at risk for high blood pressure in Minhang District of Shanghai was 25.5%. Family history of hypertension （HR=1.250， 95%CI： 1.168‒1.338）， family history of stroke （HR=1.295， 95%CI： 1.080‒1.553）， history of diabetes （HR=1.203， 95%CI： 1.076‒1.345）， daily smoking （HR=1.187， 95%CI： 1.087‒1.296）， overweight （HR=1.393， 95%CI：1.308‒1.484）， obesity（HR=1.903， 95%CI： 1.719‒2.106）， high values of normal blood pressure （HR=1.275， 95%CI： 1.195‒1.359） and advanced age （HR=1.033， 95%CI： 1.030‒1.036） were all risk factors. Emaciation （HR=0.649， 95%CI： 0.500‒0.840） was a protective factors. ConclusionBlood pressure monitoring should be strengthened for people elderly， with family history of hypertension， family history of stroke， diabetes or high values of normal blood pressure， so as to diagnose hypertension early. Timely intervention measures should be taken for community-dwellers with unhealthy lifestyles such as smoking， overweight and obesity.

With the widespread application of diving technology, the safety of long-term diving has become a research focus. Research on the chronic health effects of long-term diving on divers mainly focuses on the respiratory system, circulatory system, nervous system, skeletal system, urinary system, as well as psychological health and sleep. Long-term diving can lead to increased lung capacity, thickening of nasal mucosa, myocardial hypertrophy, changes in heart rhythm, and hearing loss in divers. The impact of long-term diving on health is influenced by diving exposure index such as diving mode, maximum diving depth, underwater stay time, diving frequency, and number of dives, as well as individual factors such as years of diving experience, age, and medical history of divers. However, research on the effects of diving on health are inconsistent, and the potential mechanisms of health damage are unclear. Future large-scale research should be conducted under strict experimental conditions and with standardized inclusion criteria for subjects. Establishing a scientific and systematic assessment method for decompression is crucial for studying the chronic health effects of divers and enhancing understanding of relevant mechanisms to promote the development of diving industry and sport.

Intravascular large B-cell lymphoma(IVLBCL)is an aggressive extranodal large B-cell lymphoma,cocurrence in the same organ with other malignancies is very rare,especially in the lung.Here,we report a rare case of lung adenocarcinoma with IVLBCL.The patient was admitted to the hospital due to diarrhea associated with fever and cough.A computed tomography(CT)scan of the chest showed an irregular patchy high-density shadow in the upper lobe of the right lung with ground-glass opacity at the margin.After admission,the patient was given anti-infection treatment,but still had inter-mittent low fever(up to 37.5 oC).The pathological diagnosis of percutaneous lung biopsy(PLB)was lepidic-predominant ad-enocarcinoma with local infiltration,which was proved to be invasive nonmucinous adenocarcinoma of the lung with IVLBCL after surgery.This paper analyzed the clinicopathological characteristics and reviewed the relevant literature to improve the knowledge of clinicians and pathologists and avoid missed diagnosis or misdiagnosis.

Objective To study the correlation between carotid bifurcation geometry and atherosclerotic plaque vulnerability using high-resolution magnetic resonance vessel wall imaging(HRMR-VWI),and to seek the potential predictor for vulnerable plaque for-mation.Methods The clinical information and imaging data of 104 patients with carotid bifurcation plaque detected by HRMR-VWI were analyzed retrospectively.Carotid bifurcation geometric parameters was measured to determine whether the carotid bifurcation plaque was vulnerable plaque,and they were divided into vulnerable plaque group(69 cases)and stable plaque group(35 cases).The difference of carotid bifurcation geometry of various groups was investigated,and the influence of common traditional risk factors to obtain independent risk factors was adjusted.Receiver operating characteristic(ROC)curve was drawn.Results Among 104 carotid artery,vulnerable plaque group had larger bifurcation angle(54.00 vs 48.80,P＜0.001),less luminal expansion(1.76 vs 1.94,P=0.002)and less outflow/inflow area ratio(0.79 vs 0.88,P＜0.001)compared with stable plaque group.After adjusting,binary logistic regres-sion indicated that bifurcation angle[odds ratio(OR)1.132 per 10° increase;95％confidence interval(CI)1.044-1.225],luminal expan-sion(OR 0.084 per 1 increase;95％CI 0.014-0.492)and outflow/inflow area ratio(OR 0.357 per 0.01 increase;95％CI 0.177-0.723)were independent risk factors of vulnerable plaque formation.Bringing them into the final model,the area under the curve(AUC)was 0.878 above the basic model(AUC=0.664).Conclusion Bifur-cation angle,luminal expansion and outflow/inflow area ratio are independently associated with vulnerable plaque formation.Carotid bifurcation geometry have the certain predictive efficiency of vulnerable plaque formation and have the incremental diagnostic value to traditional risk factors,which are expected to be effective imaging makers for the formation of vulnerable plaque.

Objective:To explore the related factors of thrombocytopenia (TCP) occurrence in patients with cirrhosis.Methods:A cross-sectional study was conducted. Inpatients with an initial diagnosis of cirrhosis at Peking University First Hospital from January 1, 2010 to December 31, 2020 were included. Clinical data such as demographic characteristics, etiology of cirrhosis, complications of cirrhosis, laboratory indicators, Child-Pugh grade, invasive procedures, and mortality during hospitalization were collected. A logistic regression model was used to explore the related factors of TCP occurrence in patients with cirrhosis. Categorical variables were compared by the χ2 test. The inter-group comparison was performed using continuous variables, a t-test, one-way analysis of variance (ANOVA), or a nonparametric test. Results:There were a total of 2 592 cases of cirrhosis. 75 cases with incomplete clinical data were excluded. 2 517 cases were included for analysis. The median age was 58 (50, 67) years. Males accounted for 64%. 1 435 cases (57.0%) developed TCP, and 434 cases (17.2%) had grade 3-4 TCP. Gender, primary biliary cholangitis (PBC), primary sclerosing cholangitis (PSC), and concomitant esophagogastric varices (EGV) were the major factors associated with TCP. Females were more prone to combine with TCP ( OR=1.32, 95% CI: 1.12-1.56, P=0.001). Patients combined with EGV ( OR=3.09, 95% CI: 2.63-3.65, P<0.001) were more prone to develop TCP, which was associated with the increased incidence of hypersplenism ( P<0.001). Patients with PBC ( OR=0.64, 95% CI: 0.50-0.82, P<0.001) and PSC ( OR=0.23, 95% CI: 0.06-0.65, P=0.010) were less prone to develop TCP, which was due to the shorter prothrombin time and better coagulation function of PBC patients ( P<0.001), and the lower proportion of hypersplenism in combined PSC patients ( P=0.004). Patients with TCP and grade 3-4 TCP had a higher rate of hemostatic procedures ( P<0.05), but a lower rate of liver biopsy ( P<0.05). Patients with grade 3-4 TCP had a higher nosocomial mortality rate compared to those without ( P=0.004). Conclusion:TCP is common in patients with cirrhosis. However, TCP occurrence is higher in female patients with EGV and lower in patients combined with PBC and PSC. TCP affects invasive procedures and is associated with adverse outcomes.

Objective To explore the therapeutic effect of bicyclol(BIC)on rat model of myocardial fibrosis and its possible mechanism.Methods Twenty-four SPF male SD rats were randomly di-vided into sham group,model group,low-and high-dose groups,with 6 rats in each group.Except for the sham group,all other groups were injected with 5 mg/(kg·d)isoproterenol by tail vein to establish myocardial fibrosis model,and the low-and high-dose groups were administered by ga-vage with 100 and 200 mg/(kg·d)BIC,respectively for 14 consecutive days.HE staining and Masson staining were used respectively to observe the severity of myocardial injury and fibrosis.Western blot assay was employed to detect the protein expression of Collagen Ⅰ,Collagen Ⅲ,al-pha smooth muscle actin(α-SMA),methyltransferase-like protein 3(METTL3),α-ketoglutarate-dependent dioxygenase AlkB homolog 5(ALKBH5)and YTH domain family protein 1(YTHDF1)in rat myocardium.Results Compared with the sham group,myocardial cell necrosis and myocardial fibrosis were significantly more serious in the model group.Low-and high-dose BIC treatment reduced myocardial cell rupture and necrosis and myocardial fibrosis when com-pared with the model group.The expression levels of Collagen Ⅰ,Collagen Ⅲ,α-SMA,METTL3 and YTHDF1(P＜0.05)were significantly higher,and that of ALKBH5(0.58±0.02 vs 0.88±0.07,P＜0.05)was notably lower in the myocardial tissues of the model group than the sham group.While,both doses of BIC treatment significantly reversed above changes in protein levels(P＜0.05).Conclusion BIC can effectively alleviate myocardial structural damage and interstitial collagen deposition in rats with isoproterenol-induced myocardial fibrosis,and its mechanism may be related to m6A methylation modification.

Objective: To understand the prevalence and pattern of abnormal uterine bleeding (AUB) among female medical college students in Shanghai，to provide a basis for menstrual health intervention for female college students. Methods: A total of 912 female medical students from a university in Shanghai were selected through cluster sampling. An anonymous questionnaire survey on menstrual history and related factors was conducted in March 2021. Results: The prevalence of AUB among female medical college students was 39.9%, with cycle disordered and non cycle disordered AUB of 24.7% and 15.2%, respectively. Among female college students with AUB, 21.7% had two or three abnormal menstrual symptoms. Multivariate Logistic analysis showed that sleep quality was associated with both types of AUB, and female undergraduates with poorer and poor sleep quality were at increased risk of both cyclic disordered AUB ( OR =2.05) and non cyclic disordered AUB ( OR =2.00). Low BMI ( OR =1.66) and weight gain and loss ( OR =1.76) were associated with cycle disordered AUB. Frequent insomnia ( OR =2.45) was associated with non cyclic disordered AUB( P <0.05). Conclusion Abnormal uterine bleeding (AUB) is common in female college students, female medical college students with AUB have multiple concurrent abnormal bleeding patterns. Factors associated with AUB varied according to the type of AUB, with sleep quality correlates with both types of AUB.
