Objective To understand the prevalence and risk factors of hyperuricemia in electronics factory workers in Wuhan, and to provide evidence for the health protection of electronics factory workers. Methods A total of 1 415 employees in an electronics factory in Wuhan were selected as the research subjects, and the physical examination and determination of various biochemical indicators, as well as questionnaire survey were carried out. Results The detection rate of hyperuricemia among workers in the electronics factory in Wuhan was 32.43%, with 36.33% for men and 14.11% for women, and the difference was statistically significant ( χ²＝46.077，P＜0.001). The detection rate of hyperuricemia was the highest (33.77%) among those with university or college education, followed by graduate students and above (31.50%). Compared with subjects with good lifestyle habits, people with drinking habits had higher hyperuricemia detection rate (49.38%), and the difference was statistically significant (P =0.001). The detection rates of hyperuricemia in those with central obesity and elevated alanine aminotransferase were 48.23% and 61.29%, respectively, which were significantly higher than those in the subjects without the above diseases (26.91% and 27.21%, respectively), and the differences were statistically significant (P <0.001). Obese people had the highest detection rate of hyperuricemia (66.95%), followed by overweight people (43.75%), and the difference was statistically significant (P <0.001). Multivariate logistic analysis showed that alcohol drinking (OR=1.836, 95% CI=1.139-2.961, P =0.013) and body mass index ≥ 24 kg/m² (OR=2.175, 95% CI=1.686 -2.806, P <0.001) were risk factors for hyperuricemia in electronic factory workers. Elevated alanine aminotransferase (ALT) was significantly correlated with hyperuricemia (OR=2.964, 95%CI=2.146-4.095 , P <0.001). Female gender was a protective factor for hyperuricemia in workers in the electronics factory (OR=0.441, 95%CI=0.297-0.653 , P <0.001). Conclusion The detection rate of hyperuricemia among workers in an electronics factory in Wuhan is high, and the detection rate of hyperuricemia in men is higher than that in women. Alcohol consumption, overweight and obesity will increase the risk of hyperuricemia. Elevated ALT is associated with hyperuricemia. Maintaining an ideal body mass index and establishing a good lifestyle play an important role in preventing hyperuricemia.

Objective To observe the effect of a new cell delivery tool(MSC exo)on the proliferation of pancreatic cancer by transferring targeted genes.Methods Transmission Electron Microscope(TEM)and Nanoparticle Tracking Analysis(NTA)were used to identify human mesenchymal stem cell exosomes(MSC-exo)and transport miR-450a-5p into CFPAC-1,to explore the effect of miR-450a-5p targeting BZW2 on inhibiting the proliferation of pancreatic cancer cells.Results The expression of miR-450a-5p was low in pancreatic cancer tissue(P<0.05),and the expression of CD63 and TSG101 of MSC-exo-miR-450a-5p in CFPAC-1 cells was higher than that of MSC-exo by Western blot(P<0.05).CCK-8 and EdU results showed that MSC-exo-miR-450a-5p significantly inhibited the proliferation of CFPAC-1 cells(P<0.05).Cell scratch and Transwell experiments showed that MSC-exo-miR-450a-5p can inhibit the migration and invasion of CFPAC-1 cells(P<0.05).Through dual luciferase assay,it was confirmed that miR-450a-5p targets BZW2,and RT-qPCR and Western blotting showed a negative correlation(P<0.05)between miR-450a-5p and BZW2 expression.Overexpression of BZW2,CCK-8,EdU,cell scratch,and Transwell experiments confirmed that pc-BZW2 reversed the anti-cancer function of MSC-exo-miR-450a-5p on CFPAC-1.Western blot detected PCNA,Ki-67,MMP2,MMP9,and the results were consistent with the above experiments(P<0.05).Conclusion hMSC exo is a new delivery system,targeting BZW2 to transport miR-450a-5p to inhibit the biological malignancy of pancreatic cancer cells,which provides an important clue for the research of targeted treatment of pancreatic cancer.

Objective:To investigate the levels of osteoporosis-related biomarkers in individuals with subclinical hypothyroidism complicated by type 2 diabetes mellitus.Methods:A cross-sectional study. From January 2021 to June 2022, 40 patients with subclinical hypothyroidism, 40 patients with type 2 diabetes, 40 patients with type 2 diabetes complicated with subclinical hypothyroidism, and 40 individuals receiving physical examination in Shanxi Bethune Hospital were selected as subjects in this study. The glucose and lipid metabolism indexes and bone metabolism indexes of the subjects were detected, and the differences and correlations of the metabolic indexes among the groups were analyzed by t-tests, nonparametric tests or correlation analysis. Results:Compared with healthy group, beta C-terminal cross-linked telopeptides of type Ⅰ collagen (β-CTX) level in type 2 diabetes group was higher [(344.60±125.61) vs (227.56±68.33) pg/ml] ( t=-5.176, P<0.001), osteocalcin (OC) and total procollagen type 1 aminoterminal peptide (t-PINP) were both lower [(15.76±4.70) vs (28.02±5.83)ng/ml, (43.49±13.63) vs (59.58±15.80) ng/ml] ( t=10.352, t=4.874, P<0.001). The β-CTX level in type 2 diabetes patients complicated with hypothyroidism was higher than that in patients with simple subclinical hypothyroidism [(380.51±122.22) vs (212.41±44.17) pg/ml] ( t=-8.180 ,P<0.001), but the levels of OC and t-PINP were both lower [(13.67±4.06) vs (26.12±4.55) ng/ml, (38.76±9.53) vs (61.50±12.31) ng/ml] ( t=12.897, P<0.001); but there was no significant difference in the three biomarkers between patients with type 2 diabetes mellitus complicated by subclinical hypothyroidism and those with type 2 diabetes mellitus alone. [β-CTX: (380.51±122.22) vs (344.60±125.61) pg/ml, OC: (13.67±4.06) vs (15.76±4.70) ng/ml, t-PINP: (38.76±9.53) vs (43.49±13.63) ng/ml] ( t=1.296,1.890,-1.799 ,all P>0.05). In the patients with type 2 diabetes mellitus complicated by subclinical hypothyroidism, the β-CTX was positively correlated with fasting blood glucose (FBG) and glycosylated hemoglobin (HbA1c)( r=0.293,0.487,all P<0.05), while OC and t-PINP were negatively correlated with FBG and HbA1c ( r=-0.560,-0.502,-0.289,-0.326, P<0.05). Conclusion:Changes of serum osteoporosis-related biomarkers in subclinical hypothyroidism patients with type 2 diabetes indicate the increased risk of osteoporosis in those patients.

Objective:This study aimed to explore the effect of Vaspin on adipose tissue macrophage polarization and its underlying mechanism.Methods:Fifty male SD rats, aged 8 weeks, were chosen and randomly allocated into three groups: the normal control(NC), the type 2 diabetes(T2DM), and various concentrations of Vaspin intervention(V1: 480 ng/kg, V2: 960 ng/kg, V3: 1 440 ng/kg). Vaspin was administered via intraperitoneal injection for 8 weeks. Glucose tolerance and insulin sensitivity were evaluated via intraperitoneal glucose tolerance test(IPGTT), intraperitoneal insulin tolerance test(IPITT) and hyperinsulinemic-euglycemic clamp. Adipose tissue inflammation and macrophage polarization were assessed using immunofluorescence, RT-PCR and western blotting.Results:After 8 weeks of intervention, there were no statistically significant differences in body weight and blood lipid levels among groups. IPGTT, IPITT, and hyperinsulinemic-euglycemic clamp experiments demonstrated that Vaspin intervention improved blood glucose and insulin sensitivity, exhibiting a dose-dependent manner( P<0.05). IF and RT-PCR showed that Vaspin downregulated the expression of CD11c, IL-1β, and TNF-α in eWAT, while upregulating the expression of CD206, IL-10, and PPARγ, which correlated with Vaspin concentration( P<0.05). ELISA revealed that Vaspin intervention reduced the concentrations of IL-1β and TNF-α in serum, while increasing the concentration of IL-10( P<0.05). Western blotting demonstrated that Vaspin downregulated iNOS protein expression, while upregulating Arg1, p-Akt, and PPARγ expression in a dose-dependent manner( P<0.05). Conclusion:Vaspin promotes M2 polarization of adipose tissue macrophages via PPARγ pathway, leading to reduced inflammation and improved insulin sensitivity in T2DM rats.

ObjectiveTo investigate the clinical efficacy of Gandouling tablet （GDL） on abnormal lipid metabolism in Wilson's disease （WD） and the correlation between the prediction model of hepatic steatosis and the related indexes of lipid metabolism in WD. MethodA total of 86 patients with abnormal lipid metabolism in WD were selected. The 24-hour urine copper， alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， serum triglyceride （TG）， total cholesterol （TC）， apolipoprotein B （ApoB）， low density lipoprotein cholesterol （LDL-C）， bile acid （BA）， γ-glutamyl transferase （GGT）， prediction model of hepatic steatosis ［hepatic steatosis index （HSI） and Zhejiang University index （ZJU index）］， ultrasonic attenuation coefficient imaging （ATT）， and traditional Chinese medicine （TCM） syndrome score were statistically analyzed before treatment. Pearson correlation test was used to analyze the correlation between TG， TC， LDL-C， ApoB， ALT， AST， ALT/AST， BA， GGT， TCM syndrome score， ATT， and HIS and ZJU. The patients were divided into an observation group and a control group by random number table method， with 43 cases in each group. The observation group was treated with GDL combined with sodium dimercaptopropane sulfonate （DMPS）， while the control group was only treated with DMPS as a control. After six courses of treatment， 24-hour urine copper， TC， TG， LDL-C， ApoB， HSI， ZJU， ATT， TCM syndrome score， and clinical efficiency before and after treatment were observed and compared between the two groups. The correlation between HSI and ZJU and serum TC， TG， LDL-C， ApoB， ALT， AST， ALT/AST， BA， GGT， TCM syndrome scores， and ATT was analyzed. ResultPearson correlation analysis showed that serum TC （r = 0.811）， TG （r = 0.826）， LDL-C （r = 0.802）， ApoB （r = 0.820）， ALT （r = 0.497）， ALT/AST （r = 0.826）， TCM syndrome score （r = 0.716）， and ATT （r = 0.736） were positively correlated with HSI （P<0.01）， while AST， BA， and GGT had no significant correlation with HSI. TC （r = 0.718）， TG （r = 0.765）， LDL-C （r = 0.667）， ApoB （r = 0.699）， ALT/AST （r = 0.403）， TCM syndrome score （r = 0.666）， and ATT （r = 0.684） were positively correlated with ZJU （P<0.01）. ALT， AST， BA， and GGT had no significant correlation with ZJU. The total effective rate of the observation group was 86.05 （37/43）， and that of the control group was 72.09% （31/43）. The total effective rate of the observation group was higher than that of the control group （Z = -2.301， P<0.05）. After treatment， the 24-hour urine copper of the two groups increased significantly. The levels of TC， TG， LDL-C， and ApoB were significantly decreased， and the HSI， ZJU， and ATT were significantly decreased （P<0.01）. Compared with those in the control group after treatment， the above indexes improved better in the observation group （P<0.05， P<0.01）. ConclusionGDL can effectively improve the level of copper and lipid metabolism in patients with WD， with high clinical safety and good clinical application value. The prediction model of hepatic steatosis can effectively reflect the degree of abnormal lipid metabolism in WD.

Objective To investigate the diagnostic value of serum levels of leukocyte cell derived chemo-taxin 2(LECT2)and tumor necrosis factor ligand-related molecule-1A(TL1A)in children with atopic der-matitis(AD).Methods A total of 83 children with AD who were adimitted to the hospital from August 2021 to August 2023 were selected as the AD group,and 83 healthy children who underwent physical examination in the hospital during the same period were selected as the control group.Enzyme linked immunosorbent assay(ELISA)was applied to measure the expression levels of LECT2 and TL1A in serum.Spearman method was applied to analyze the correlation between serum LECT2,TL1A,and AD integral index(SCORAD).Multiva-riate Logistic regression was applied to analyze the factors that affected the severity of AD in children.Receiv-er operating characteristic(ROC)curve was applied to analyze the diagnostic efficacy of serum LECT2 and TL1A levels on the severity of AD in children.Results Compared with the control group,the expression lev-els of LECT2 and TL1A in the serum of the AD group were significantly increased(P＜0.05).Compared with the low-grade group,the serum LECT2,TL1 A,SCORAD score,EOS and total IgE in the moderate and severe groups were significantly increased in turn(P＜0.05).According to Spearman correlation analysis,the serum levels of LECT2 and TL1A in the AD group were positively correlated with the SCORAD score(r=0.776,0.693,both P＜0.05).According to the results of multivariate Logistic regression analysis,serum LECT2、TL1 A、EOS and total IgE were risk factors affecting the severity of AD in children(P＜0.05).In ad-dition,the combination of serum LECT2 and TL1A had the highest AUC for diagnosing the severity of AD in children,which was better than the individual diagnosis of serum LECT2 and TL1A(Z=2.249,1.989,P=0.025,0.047).Conclusion The elevated levels of serum LECT2 and TL1A in children with AD are closely re-lated to the severity of the disease,and the combination of the two can better evaluate the severity of the dis-ease in children with AD.

The development mode of public hospitals has shifted from scale expansion to improving quality and efficien-cy,and specialized operation and management is an important means to improve the performance of surgical departments.Howev-er,at present,there is a gap in the performance appraisal of specialized operators,requiring the hospital to formulate a specific and accurate performance appraisal plan for the management department.Taking hospital Z as an example,based on post value(IPE),this paper analyzes the idea of its performance appraisal plan in detail,and analyzes the specific application of its per-formance allocation with specialized operation assistant as an example.Based on IPE,the responsibility,rank and performance distribution coefficient of hospital management positions can effectively solve the difficulties that the total work and quality of hos-pital management departments are difficult to quantify,and also provide some reference for the formulation of performance apprais-al plan of specialized operation staff in public hospitals.

Objective:To investigate the efficacy of neostigmine combined with raw rhubarb enema on severe acute pancreatitis (SAP) patients with intra-abdominal hypertension (IAH).Methods:The clinical data of 89 SAP patients, who were admitted and underwent continuous renal replacement treatment (CRRT) in intensive care unit (ICU) department of the First Affiliated Hospital of Hebei North University from January 2018 to June 2022, were retrospectively analyzed. Patients were divided into control group ( n=44) and experimental group ( n=45) according to the treatment mode. Raw rhubarb enema plus sodium sulfate topical application were administrated twice a day for 7 days in control group; besides the treatment above, intramuscular injection of neostigmine 0.5 mg twice a day for 7 days was given in experimental group. Intra-abdominal pressure was monitored, acute physiology and chronic health evaluation (APACHE)Ⅱ, kidney disease: improving global outcome stage (KDIGO), lung injury score (LIS) were recorded, and serum leukocyte, CRP, procalcitonin (PCT), IL-6, IL-8 and tumor necrosis factor (TNF)-ɑ level were examined before and after treatment in both groups. The primary endpoint was the amount change of intra-abdominal pressure within 24 hours, and secondary endpoints included increased fecal volume within 7 days after treatment, new abdominal compartment syndrome (ACS), new organ dysfunction, vascular complications, length of ICU stay, total length of stay, survival rate and treatment intervention and occurrence of complications within 6 months after the end of treatment. Results:Intra-abdominal pressure began to decrease at 9 hours after treatment both in control group and experimental group. Compared with that before treatment, the intra-abdominal pressure of the two groups decreased significantly after 7 days of treatment, and the decrease rate of the experimental group within 7 days was obviously higher than that of the control group, with statistical significance (all P values <0.05). Compared with those before treatment, APACHEⅡ, KDIGO and LIS in both groups were significantly decreased, but the decreases in experimental group were more remarkable than those in control group (all P values <0.05). After treatment, the serum WBC count and the levels of inflammatory factors CRP, PCT, IL-6, IL-8, TNF-ɑ in experimental group were obviously lower than those in control group with statistical significance (all P values <0.05). Compared with control group, the change of intra-abdominal pressure in experimental group was significantly increased after 24-hour treatment, and the fecal volume was also obviously increased on day 1, 2, 3, 5 and 7 after treatment (all P values <0.05). However, there were no significantly statistical differences on the severity of intra-abdominal pressure, new occurrence of ACS and organ failure, vascular complication, ICU hospitalization and total length of stay and survival rate between two groups. After 6-month follow-up, the recurrence of pancreatitis and its treatment intervention between two groups were not statistically significant. Conclusions:The adjuvant treatment of neostigmine could reduce intra-abdominal pressure, increase defecation volume in SAP patients and alleviate SAP condition, which might be related to reducing the release of inflammatory cytokines.

Objective:Through meta-analysis, the association of three common adipokines (leptin, adiponectin, and chemerin) with bone nutrition of senile osteoporosis (SOP) in China was systematically evaluated.Methods:CNKI, CBM, VIP, Wanfang, PubMed, Web of Science, Embase, Cochrane Library, and other databases were searched for articles published from the establishment of the database to July 30, 2022. After literature screening, data extraction, and quality evaluation of the included studies were independently conducted by two researchers, a meta-analysis was performed using RevMan5.4 and Stata17.0 softwares.Results:A total of 13 studies in the Chinese population were included, including 897 patients with SOP and 673 elderly with normal bone mineral density . The results of the meta-analysis showed that compared with the control group, the serum leptin levels were significantly lower ( MD -2.64, 95% CI -4.04 to -1.23, P < 0.001), chemerin levels were significantly higher ( MD 25.23, 95% CI 14.57 to 35.90, P < 0.001), and adiponectin levels were not significantly different ( MD -0.55, 95% CI -2.26 to 1.17, P > 0.05) in SOP patients. After subgroup analysis according to the measurement method, leptin levels remained lower in SOP patients than in the control group. Conclusions:Compared with the control group, leptin levels were lower and chemerin levels were higher in SOP patients. Therefore, dysregulation of adipokines may play an important role in the occurrence and development of SOP, and regulation of adipokine levels and functions may play a role in the treatment of SOP and the improvement of bone nutrition as a nutritional intervention.
