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 explore the effect of exercise on anxiety and depression in cancer patients during chemotherapy, as well as the optimal exercise dosage. MethodsA PICO framework was constructed, and randomized controlled trials (RCTs) on the effect of exercise on anxiety and depression in cancer patients during chemotherapy were retrieved from databases of PubMed, Web of Science, Cochrane Library, Embase, Medline, CNKI, VIP and Wanfang data, from the establishment to November, 2023. The quality of the literature was evaluated with Cochrane Risk of Bias Tool and Physiotherapy Evidence Database (PEDro) scale. Data were synthesized and analyzed using RevMan 5.3, and the risk of bias was evaluated using Stata 18.0. ResultsA total of 13 RCTs involving 1 340 subjects were included. The scores of PEDro scale were five to eight. Exercise interventions significantly improved anxiety (SMD = -0.70, 95%CI -1.18 to -0.22, P = 0.004) and depression (SMD = -0.89, 95%CI -1.43 to -0.34, P = 0.002) compared to the control group. Subgroup analyses showed that, the exercise effect on anxiety was less than 45 minutes a time (SMD = -0.26, 95%CI -0.46 to -0.05, P = 0.01), more than three times a week (SMD = -0.26, 95%CI -0.46 to -0.05, P = 0.01), and less than twelve weeks (SMD = -0.21, 95%CI -0.36 to -0.07, P = 0.005). For depression, it was less than 45 minutes a time (SMD = -0.69, 95%CI -1.29 to -0.08, P = 0.03), more than three times a week (SMD = -0.69, 95%CI -1.29 to -0.08, P = 0.03), and less than twelve weeks (SMD = -0.52, 95%CI -0.92 to -0.13, P = 0.01). Moderate to high-intensity exercise interventions significantly outperformed the control group in improving anxiety (SMD = -0.21, 95%CI -0.37 to -0.06, P = 0.007) and depression (SMD = -0.21, 95%CI -0.41 to -0.01, P = 0.04). ConclusionExercise interventions can effectively improve anxiety and depression in cancer patients during chemotherapy, and it suggests for high-intensity exercise, less than 45 minutes a time, more than three times a week, and less than twelve weeks.

AIM: To investigate the alterations in corneal aberration and relative refractive power following the reduction of back optic zone diameters(BOZD)of orthokeratology lenses.METHODS: Myopic children aged 8-12 years, deemed suitable and willing to wear orthokeratology lenses, were randomly allocated to wear lenses with a 6.0 mm BOZD or a 5.0 mm BOZD. Data collection included changes in higher-order aberrations, relative refractive power and the treatment zone diameter of the two groups after wearing lenses for 1 d, 1 wk, 1, and 3 mo. The correlation of increase in corneal higher-order aberrations with refractive power was analyzed.RESULTS: The increases in total higher-order aberrations, spherical aberrations and coma aberrations varied over time following lens wear(all P<0.001), and there were no statistically significant differences in the changes of total higher-order aberrations and coma aberrations between the two groups of patients(all P>0.05). A significant difference was observed in the increment of spherical aberrations in the 5 mm range between the two groups of patients, which varied over time(Ftime=40.179, Ptime<0.001; Fgroup=11.948, Pgroup=0.001; Finteraction=3.262, Pinteraction=0.03). A significant difference was observed in the increment of spherical aberrations in the 4 mm range between the two patient groups(Ftime=34.462, Ptime<0.001; Fgroup=13.094, Pgroup<0.001; Finteraction=1.372, Pinteraction=0.25). There was no statistically significant distinction in relative refractive power between the two groups(Fgroup=0.048, Pgroup=0.83; Finteraction=1.208, Pinteraction=0.31); however, relative refractive power changed over time(Ftime=40.030, Ptime<0.001). The difference in treatment zone diameter between the two groups was statistically significant, with changes over time(Ftime=11.212, Ptime<0.001; Fgroup=74.073, Pgroup<0.001; Finteraction=0.312, Pinteraction=0.82). The total higher-order aberrations, spherical aberrations, and coma aberrations in 4, 5 and 6 mm range showed a positive correlation with relative refractive power values(all P<0.001). Statistically significant difference was observed in the axial length between the two groups after wearing lenses for 3, 6 and 12 mo(Ftime=185.398, Ptime<0.001; Fgroup=5.618, Pgroup=0.02; Finteraction=2.315, Pinteraction=0.11).CONCLUSION: Orthokeratology lenses leaded to elevated higher-order aberrations. Orthokeratology lenses with smaller BOZD produced significantly greater spherical aberrations at 4 and 5 mm range and smaller treatment zone diameters. The corneal total higher-order aberration was positively correlated with relative refractive power. Wearing orthokeratology lenses with a smaller BOZD can cause slower axial growth and better myopia control.

ObjectiveTo investigate the effects of retention enema with Huangling Jiedu Xiezhuo granules（HJXG） on Nod-like receptor protein 3（NLRP3）， intestinal flora， and short-term prognosis in patients with gout. MethodsA total of 60 patients with gout admitted to the hospital from January 2021 to December 2023 were selected and divided into a control group and an observation group according to the random number table method， with 30 cases in each group. The control group was treated with febuxostat， and the observation group was treated with retention enema with HJXG on the basis of the control group. After 14 days of continuous treatment， the clinical efficacy， traditional Chinese medicine （TCM） syndrome score， and visual analogue scale （VAS） pain index of the two groups were compared， and serum creatinine（SCr）， blood urea nitrogen（BUN）， uric acid（UA）， cystatin C（CysC）， β₂- microglobulin（β₂-MG）， glomerular filtration rate test（GFR）， creatinine clearance rate （Ccr）， erythrocyte sedimentation rate（ESR）， hypersensitive C-reactive protein，（hs-CRP）， interleukin 6（IL-6）， interleukin-1β（IL-1β）， interleukin-18 （IL-18）， NLRP3 inflammasome levels， and the number of intestinal flora were detected in the two groups. The prognosis of patients was followed up within 12 weeks. COX regression analysis was used to analyze the effect of short-term prognosis. ResultsAfter treatment， TCM syndrome scores and VAS pain index in both groups were reduced （P<0.05）， and TCM syndrome scores in the observation group were significantly lower than those in the control group. After treatment， ESR， hs-CRP， IL-6， NLRP3， IL-18， and IL-1β were significantly decreased in both groups （P<0.01）， and the levels of IL-6， ESR， NLRP3， and IL-18 were significantly improved in the observation group compared with the control group （P<0.05）. BUN， SCr， UA， β₂-MG， GFR indexes in both groups were significantly lower after treatment， Ccr indexes in both groups were significantly higher after treatment， and the levels of SCr， UA， CysC， and Ccr in the observation group were significantly better than those in the control group （P<0.05）. After treatment， the intestinal flora in both groups was improved， and the observation group was significantly improved compared with the control group in terms of Lactobacillus， Proteus， Bacteroides， and Escherichia coli （P<0.05）. COX regression analysis showed that retention enema with HJXG could reduce the risk of poor short-term prognosis in patients with gout compared with Western medicine alone. ConclusionThe retention enema with HJXG can improve the curative effect of patients with gout， improve the TCM syndromes， reduce inflammation， and enhance renal function， intestinal flora， and short-term prognosis.

BACKGROUND:Ferroptosis is an iron-dependent regulatory form of cell death characterized by iron-dependent lipid peroxidation.Long-chain acyl-coenzyme A synthase 4(ACSL4)is involved in the formation of lipid peroxidation substrates,thereby resulting in ferroptosis.Recent studies have shown that ACSL4-mediated ferroptosis plays a key role in atherosclerotic cardiovascular disease. OBJECTIVE:To summarize the structural function and regulatory mechanism of ACSL4 and its potential molecular mechanism mediating ferroptosis,and to elaborate the application of ACSL4 driving ferroptosis in atherosclerosis,ischemic stroke and myocardial infarction,in order to provide a new therapeutic strategy for the treatment of atherosclerotic cardiovascular diseases. METHODS:Relevant literature was searched in PubMed database from database inception to August 2023 using the keywords of"atherosclerosis,ferroptosis,long-chain acyl-coenzyme A synthase 4,ACSL4,glutathione peroxidase 4,ischemic stroke,myocardial infarction,endothelial cell,smooth muscle cells,foam cell."Finally,76 documents were included for review and analysis. RESULTS AND CONCLUSION:ACSL4 participates in the formation of coenzyme derivatives of polyunsaturated fatty acids and inserts them into phospholipids to provide substrates for lipid peroxidation,the core mechanism of iron death.Among the regulatory factors of ACSL4 expression,integrin α6β4,intracellular vesicular transport factor p115,and zinc lipoprotein A20 negatively regulate its expression.Meanwhile,multiple miRs down-regulate its expression by binding to 3'-UTR.On the contrary,up-regulation of ACSL4 is mostly regulated by transcription factors.ACSL4-dependent production of phospholipids containing polyunsaturated fatty acids is an essential prerequisite for lipid peroxidation and ferroptosis.Moreover,ACSL4 and glutathione peroxidase 4 are mutually dependent as positive and negative regulators of ferroptosis,and their specific mechanisms remain to be further studied.ACSL4-mediated ferroptosis is involved in the pathological mechanism of atherosclerosis,ischemic stroke,and myocardial infarction.Endothelial cell injury in atherosclerosis is closely related to ACSL4-mediated ferroptosis,but there are no reports on the involvement of ACSL4 in foam cell formation,smooth muscle cell phenotype transformation,and calcification.ACSL4 has become a research hotspot as a biomarker and potential target of ferroptosis.Targeting ACSL4 to inhibit ferroptosis may become a new direction for the treatment of atherosclerotic cardiovascular diseases.However,there are few studies on drugs inhibiting ACSL4,and further studies are needed in the future.

ObjectiveTo observe the effect of Shenshu Fujian decoction on platelet-derived growth factor （PDGF）/naked cuticle homolog 2 （NKD2） /Wnt signaling pathway in rats with chronic renal failure （CRF）. MethodsSixty male SD rats were randomly divided into normal group， model group， Niaoduqing group （5 g·kg^-1）， low-dose Shenshu Fujian decoction group （5.5 g·kg^-1）， medium-dose Shenshu Fujian decoction group （11 g·kg^-1）， and high-dose Shenshu Fujian decoction group （22 g·kg^-1）， with 10 rats in each group. A CRF rat model was established by feeding a 0.5% adenine diet for 21 days. After successful modeling， intragastric administration was given once daily for 28 consecutive days. After treatment， the renal morphology of rats was observed. Serum creatinine （SCr） and blood urea nitrogen （BUN） levels were detected. Hematoxylin-eosin （HE） staining and Masson staining were used to detect renal histopathological changes， and collagen volume fraction （CVF） was calculated. Serum levels of inflammatory markers interleukin （IL）-1β and IL-6 were measured using enzyme-linked immunosorbent assay （ELISA）. The expressions of fibronectin 1 （FN1）， type Ⅰ collagen （ColⅠ）， α-smooth muscle actin （α-SMA）， platelet-derived growth factor receptor-β （PDGFR-β）， NKD2， dishevelled protein 2 （DVL2） and β-catenin in renal tissue were detected by immunohistochemistry and Western blot. ResultsCompared with the normal group， the model group showed significant renal pathological changes， a markedly increased kidney weight/body weight ratio （P<0.01）， significantly elevated CVF （P<0.01）， and notably increased serum levels of SCr， BUN， IL-1β， and IL-6 （P<0.01）. Expression levels of FN1， ColⅠ， α-SMA， PDGFR-β， NKD2， DVL2， and β-catenin in renal tissue were also significantly increased （P<0.01）. Compared with the model group， all treatment groups showed significantly decreased kidney weight/body weight ratios and CVF （P<0.01）， as well as markedly decreased serum SCr， BUN， IL-1β， and IL-6 levels. Protein expression levels of FN1， ColⅠ， α-SMA， PDGFR-β， NKD2， DVL2， and β-catenin in renal tissue were decreased， with more pronounced effects observed in the Niaoduqing， medium-dose， and high-dose Shenshu Fujian decoction groups （P<0.05， P<0.01）. ConclusionShenshu Fujian decoction improves renal function， reduces inflammation， and reverses renal fibrosis in CRF rats， possibly by downregulating the expression of PDGF/NKD2/Wnt signaling pathway-related proteins.

Objective To investigate the prevalence and influencing factors of thyroid enlargement in school-age children in Tianjin. Methods School-age children were randomly selected in Tianjin to undergo thyroid ultrasound examination, and salt iodine, urine iodine, height, and weight tests. A questionnaire survey was conducted. Univariate and multivariate regression models were used to analyze the risk factors for thyroid enlargement. Results A total of 917 children aged 7-13 years in Tianjin were surveyed, with a thyroid enlargement rate of 4.03% and a median thyroid volume of 2.60 ml. There was a non-linear relationship between children's body mass index (BMI) and the incidence of thyroid enlargement in children (P=0.008), and a linear relationship between children's body surface area (BSA) and the incidence of thyroid enlargement in children (P<0.001). Being 9 years old (OR=3.728, 95%CI: 1.343-10.343, P=0.012), obesity (OR=3.886, 95%CI: 1.801-8.384, P=0.001), having lunch at school (OR=3.157, 95%CI: 1.497-6.658, P=0.003) and frequent consumption of preserved foods (OR=4.611, 95%CI: 1.643-12.945, P=0.004) were risk factors for goiter in children. Regular consumption of seaweed (OR=0.305, 95%CI: 0.100-0.927, P=0.036) was a protective factor for goiter in children. Conclusion The incidence of thyroid enlargement in children in Tianjin meets national standards. Obesity, eating lunch at school, frequently consuming pickled foods, and being 9 years old may be risk factors for thyroid enlargement in children. Eating seaweed or kelp regularly is a protective factor. At the same time, attention should be paid to the relationship between BMI, BSA, and thyroid enlargement rate in children..

Objective To explore the association between different levels of fluoride exposure and dyslipidemia in elderly people, and to analyze the influencing factors and their interactions. Methods A total of 1 143 elderly people over 60 years old were randomly selected from historical high water fluorosis areas and control areas in Tianjin. Logistic regression model and classification tree model were used to analyze the influencing factors of dyslipidemia, and to analyze the interaction between high fluoride exposure and relevant influencing factors on dyslipidemia. Results The prevalence of elevated low density lipoprotein cholesterol (LDL-C) was 5.69% (65/1 143). There was a significant difference in the prevalence of high LDL-C in different fluoride-exposed areas (2 = 0.092，P = 0.762). Multivariate logistic analysis showed that high fluoride exposure (OR=2.306，95%CI：1.185-4.491) and abdominal obesity (OR=2.274，95%CI：1.299-3.978) were risk factors for high LDL-C, while type B personality (OR=0.529，95%CI：0.308-0.908) was a protective factor for high LDL-C. The results of classification tree model showed that abdominal obesity contributed the most to the prevalence of high LDL-C in the elderly, followed by high fluoride exposure and hyperglycemia. There was a significant multiplicative interaction between high fluoride exposure and abdominal obesity on dyslipidemia (OR=5.191,95%CI：1.609-16.745，P=0.006). Conclusion High fluoride exposure may increase the risk of high LDL-C, and there is a multiplicative interaction between high fluoride exposure and abdominal obesity on dyslipidemia.

Objective To monitor the antibody levels against measles, mumps and rubella in healthy population in Pudong New Area of Shanghai from 2018 to 2022, so as to provide evidence for the improvement of immunization strategy.Methods A total of 1 305 healthy people from 16 communities in Pudong New Area, Shanghai were randomly sampled and divided into12 age groups(0 ～ < 8 months old to ≥ 50 years old). The levels of IgG antibodies against measles, rubella and mumps in venous blood serum were detected by ELISAResults One sample was discarded because no results were detected. In 1 304serum samples, the positive rates of measles, rubella and mumps IgG antibodies were 63. 65%, 48. 39% and 58. 21%, and the geometric mean concentrations(GMCs) of the antibodies were 229. 74 mIU/mL, 11. 63 IU/mL and 76. 43 U/mL, respectively.The positive rates of measles, rubella and mumps IgG antibodies(χ~2= 0. 01-4. 874, each P > 0. 05) and GMCs(t = 0. 020-2. 583,P > 0. 05) in the serum of healthy people of different genders and household registrations showed no statistically significant difference, while the positive rates of IgG antibodies(χ~2= 16. 865-667. 297, each P < 0. 01) and GMCs(t = 5. 862-117. 019,each P < 0. 001) in the serum of healthy people with different age, year and vaccination history exhibited statistically significant differences.Conclusion The antibody levels of measles, rubella and mumps among healthy population in Pudong New Area of Shanghai are related to the year, age and immunization history, and there is still a certain risk of infection. It is suggested to strengthen the monitoring of immune status of healthy population and vaccination of women at childbearing age related to measles, mumps and rubella, which will help reduce the risk of measles, rubella and mumps in healthy population under vaccination age.
