ObjectiveTo investigate the prevalence and its influencing factors of hyperuricemia (HUA) among the employed individuals who undergo occupational health screening in Shanghai, so as to provide a scientific basis for the prevention and control of HUA and for the health promotion in this population. MethodsCluster sampling methods were performed to recruit all the employed individuals who underwent routine health check-ups at the Shanghai Health and Medical Center from January to December 2023. Relevant data, including physical examination results, laboratory tests, and questionnaire surveys, were collected for analyses. Based on the diagnostic criteria for HUA, participants were categorized into HUA group and non-HUA group. Logistic regression analysis was used to identify the influencing factors of HUA. ResultsThe detection rate of HUA in the employed population of Shanghai was 23.26%, with a significantly higher rate in males (31.12%) than that in females (10.43%) (χ²=381.853,P<0.001). The detection rate of HUA increased with age (χ²_trend=5.728, P_trend=0.017). Logistic regression analysis revealed that males had a higher risk for HUA the females, with overweight, obesity, meat-predominant diet, hypertension, and dyslipidemia being positively correlated with HUA risk. While, individuals aged 40‒ and 50‒ years had a lower risk for HUA compared with those aged 20‒ years. ConclusionThe prevalence of HUA among the employed individuals who undergo health check-ups in Shanghai is relatively high. Attention should be paid to maintaining a healthy lifestyle and keeping a balanced diet. Targeted health management should prioritize for males, individuals with hypertension and BMI overweight and obesity, and those with dyslipidemia to reduce the risk of HUA.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

ObjectiveTo investigate the effects of maltol aluminum exposure on miR-193a-3p, demethylase AlkB homolog 5 (ALKBH5), phosphatase and tensin homolog deleted on chromosome ten (PTEN) and protein kinase B (AKT), and whether miR-193a-3p is involved in aluminum-induced cognitive impairment by regulating ALKBH5/PTEN/AKT signaling pathway. Methods Specific pathogen-free male SD rats were randomly divided into control group and low-, medium- and high- dose groups according to their body weight, with eight rats in each group. Rats in the low-, medium-, and high- dose groups were intraperitoneally injected with maltol aluminum solution at concentrations of 10.00, 20.00, and 40.00 μmol/kg body weight, respectively, while the rats in control group were given an equal volume of 0.9% sodium chloride solution. Rats were injected for five days every week for three months. After injection, the novel object recognized test was used to assess the learning and memory ability of the rats. The relative expression of miR-193a-3p and B-cell lymphocytoma-2 (Bcl-2), Bcl-2 associated X protein (Bax) and cysteine aspartate protease-3 (Caspase-3) mRNA in rat hippocampus was detected using the real-time quantitative polymerase chain reaction. The relative protein expression of ALKBH5, PTEN, and AKT2 in the rat hippocampus was detected using Western blot. Results The discrimination index and the preference index of the new object recognition test of the rats in high-dose group were lower than those in control group and low-dose group (all P<0.05). The relative expression of miR-193a-3p and Bcl-2 mRNA in the hippocampus of the rats in high-dose group was lower than those in control group and low-dose group (all P<0.05). The relative mRNA expression of Bax in the high-dose group was higher than those in the control group and low-dose group (both P<0.05). The relative mRNA expression of Caspase-3 of the rats in the high-dose group was higher than that in the other three groups (both P<0.05). The relative protein expression of ALKBH5 in the hippocampus of the rats in the high-dose group was lower than that in the control group (P<0.05). The relative expression of PTEN protein was higher than those in the control group and low-dose group (both P<0.05). The relative protein expression of AKT2 was lower than those in the control group and low-dose group (both P<0.05). Conclusion Sub-chronic aluminum exposure can inhibit the expression of miR-193a-3p in the hippocampus of rats, which may disrupt the ALKBH5/PTEN/AKT pathway and affect normal neuronal homeostasis and cellular function. This pathway may play an important role in aluminum-induced cognitive impairment.

AIM:To investigate the effects of subchronic aluminum exposure on the expression of silent infor-mation regulator(Sirt1),Kelch-like ECH-associated protein 1(Keap1),nuclear factor E2-related factor 2(Nrf2),and microRNA-128-3p(miR-128-3p)in the hippocampus of rats.Additionally,we aimed to explore the mechanism of miR-128-3p and the Sirt1-Keap1/Nrf2 signaling pathways in aluminum-induced cognitive impairment in rats.METHODS:Thirty-two healthy 6-week-old SPF male SD rats,weighing(190±20)g,were randomly divided into four groups based on body weight:control group,low-dose(10 μmol/kg)group,medium-dose(20 μmol/kg)group,and high-dose(40 μmol/kg)group,with 8 rats in each group.The rat exposure model was established by intraperitoneal injection of maltol alumi-num.The Morris water maze test was used to assess the learning and memory ability of the rats.Western blot analysis was performed to measure the protein expression of Sirt1,Keap1 and Nrf2 in the hippocampus,while RT-qPCR was used to measure the expression of miR-128-3p in the hippocampus.The level of reactive oxygen species(ROS)in the cerebral cor-tex was detected using fluorescence staining in frozen sections.RESULTS:(1)In the positioning cruise experiment,the escape latency of the aluminum exposure group was significantly higher than that of the control group on the 3rd,4th,and 5th days(P＜0.05).On day 6,the number of times the rats crossed the platform and the platform quadrant in the high-dose group was reduced compared to the control and low-dose groups(P＜0.01).(2)The expression levels of Sirt1 and Nrf2 in the hippocampal tissues of all groups decreased gradually with increasing maltol aluminum exposure dose.The ex-pression level of Keap1 increased gradually with increasing maltol aluminum exposure dose.The expression level of miR-128-3p in the high-dose group was significantly higher than that in the control group(P＜0.05).(3)The content of gluta-thione peroxidase in the hippocampus of rats decreased with increasing exposure dose,while ROS levels gradually in-creased.CONCLUSION:Subchronic aluminum exposure can increase the expression of miR-128-3p in the rat hippo-campus and suppress the Sirt1-Keap1/Nrf2 signaling pathway.This inhibition prevents the activation of the Sirt1-Keap1/Nrf2 signaling pathway,leading to a reduced antioxidant capacity.The imbalance in the antioxidant system in rats results in oxidative damage to nerve cells and a subsequent decline in cognitive function.

Objective:To investigate the clinical effect of free superficial circumflex iliac artery flap combined with anterolateral thigh flap in repairing large skin defect of the hand.Methods:A retrospective case series study was conducted to analyze the clinical data of 9 patients with large skin defect of the hand admitted to Ningbo No.6 Hospital from January 2016 to December 2019，including 7 males and 2 females，aged 31-63 years［（45.3±5.6）years］. The area of skin defect reanged from 20 cm×15 cm to 25 cm×20 cm. One side of the superficial circumflex iliac artery flap and the contralateral anterolateral thigh flap were used for repair. Both recipient and donor sites were sutured at the first stage. The ilioinguinal region and thigh donor region were sutured directly. The area of superficial circumflex iliac artery flap was from 19 cm×6 cm to 23 cm ×10 cm and that of anterolateral thigh flap was 19 cm×9 cm to 23 cm×8 cm. The flap survival，healing of donor and recipient area and complications were observed. At 1，6 and 12 months after operation，the function of the flap was evaluated by the late functional evaluation criteria of the flap，hand function by the upper limb functional evaluation criteria of the Chinese Medical Association，and scar condition of the donor site by Vancouver Scar Scale（VVS）. At the last follow-up，the color，elasticity，appearance and scar of the donor site were observed.Results:All patients were followed up for 6-18 months［（12.5±2.3）months］. All flaps survived successfully. All patients achieved donor-site healing at the first stage，except that one patient experienced incision dehiscence in the thigh donor site after operation and healed after the second stage suture. The texture and appearance of the flaps were good. The flap in 5 patients was obviously bloated. Therefore，the secondary skin flap repair was selected，and the appearance was significantly improved after operation. Scores for function of the flap and the hand were improved over time（ P<0.05）. At 12 months after operation，the function of the flap was excellent in 3 patients，good in 4 and fair in 2，with the excellent and good rate of 78%；the result of hand function was excellent in 3 patients，good in 3 and fair in 3，with the excellent and good rate of 67%. The VVS score of the donor site decreased from（9.7±1.3）points at postoperative 1 month to（5.7±0.9）points at postoperative 6 months and（3.4±0.8）points at postoperative 12 months（ P<0.05）. At the latest follow-up，the color and elasticity of the flap was similar to that of the surrounding skin tissue，only with slight bloating；the scar of the donor site was small. Conclusions:The free superficial circumflex iliac artery flap combined with anterolateral thigh flap can cover large skin defect of the hand at one time，with good appearance and texture of the flap. The appearance and function of the wounded hand are good after operation，leaving only linear scar in the donor site.

Objective To investigate the effect of clotrimazole on apoptosis of hepatic cells after ischemia-reperfusion injury and its mechanism. Methods Hepatic ischemia-reperfusion rat model was established. Thirty-two male Sprague-Dawley rats were randomly allocated into sham-operated group, model control group, low dose clotrimazole group and high dose clotrimazole group. Apoptosis in hepatic tissue was assessed by TUNEL method. Protein expression levels of CYP3A1,Bcl-2,Bax and PARP were measured by Western blotting. Results As compared with model control group, the apoptosis rate, tissue injury,activity of plasma enzymes and the Bax/Bcl-2 expression ratio were reduced in low and high dose clotrimazole groups. The apoptotic index in both clotrimazole-treated groups was lower than that of model control group with statistically significant difference. CYP3A1 expression was significantly induced by clotrimazole compared to the sham-operated group. Conclusion Clotrimazole may inhibit apoptosis of hepatic cells by up-regulating Bcl-2 and down-regulating Bax, thus produce a protective effect on hepatic ischemia-reperfusion injury and it is also related to the inhibition of PARP shear.

Objective To compare the performance of 2 kinds of quantitative detection method the chemiluminescence immu-moassay and the enzyme-linked immunosorbent assay(ELISA)for detecting serum human epididymis geneproduct 4(HE4),and to explore the accuracy and practical value of the two methods.Methods In accordance to the document EP9-A2 of NCCLS,the Roche automatic electrochemical immunoassay system as the comparative method(X)and the ELISA as the testing method(Y )were per-formed according to the requirements of the detection kits.Results The serum HE4 level could be accurately reflected by the two methods.The correlation coefficient(r)in comparing these two kinds of method was ≥0.975,which showed that there was a high correlation between them.The detection results of the two methods were compared by paired sample t-test,and no statistically sig-nificant difference was found between them(P >0.05).Conclusion Because of CLIA′88 giving no specific medical decision level of HE4 and clinical acceptable level,therefore the expected bias of credibility interval can not be calculated or whether being clinically acceptable is unable to be judged.Based on the comparison of paired sample t test,these two kinds of detection methods can be used interchangeably to a certain extent.

Objective To investigate the prevalence of gestational transient thyrotoxicosis(GTT) and analyze the cause of thyrotoxicosis encountered in this period MethodsAn epidemiologic survey in ten hospitals in Shenyang was performed and 534 pregnant women during the first trimester of pregnancy filled questionaire,received physical examination and had serum thyroid-stimulating hormone(TSH),free T4 (FT4),free T3(FT3),thyroid peroxjdase antibody(TPOAb),thyrotrophin receptor antibody(TRAb),and human chorionic gonadotrophin(hCG)tests.Results(1)The total prevalence of thyrotoxicosis was 9.75%(52/534)in the first trimester and the prevalence of Grrr was 7.86%.which accounted for 80.77%of the thyroxicosis encountered in this period.A total of 88.89%of the overt GTT showed only elevated FT3 level.(2)The level of serum hCG increased gradually in the first trimester.The medians of hCG were 25 300,85 220 and 81 780 IU/L 6,8-10 and 12 weeks after gestation.respectively(P=0.000).The medians of serum TSH were 1.45.1.10 and 0.84 mlU/I,6.8-10 and 12 weeks after gestation,respectively(P＜0.01).(3)When segum hCG was more than 50 000 IU/L,the prevalece of GTT increased obviously.When serum hCG was between 80000 IU/L and 110000 IU/L,subclinical GTT increased significantly.When serum hCG was more than 110000 IU/L,overt GTT increased significantly.Correlation analysis showed that serum hCG was related negatively with TSH(r=-0.402,P=0.000)and positively with FT3(r=0.165,P=0.000),but not related with FT4.Conclusions The prevalence of GTT is 7.86%in the first trimester and it is the main cause of thyrotoxicosis found in the first trimester,accounting for 80.77%of all the causes.The serological characteristic of overt GTT is mainly the elevation of serum FT3 leveL Serum hCG level is related with the severity of GTT.
