ABSTRACT
Objective@#To explore the relationship between insulin resistance and plasma hypersensitive reactive protein (hs-CRP) in patients with chronic schizophrenia.@*Methods@#A total of 247 inpatients with chronic schizophrenia (patient group) and 166 cases of normal individuals(control group) were enrolled.Their general demographic and clinical data were collected, fasting blood glucose, hs-CRP, c-peptide and insulin indexes were tested, and insulin resistance index (HOMA-IR) was calculated.The insulin resistance level of the patients group and the control group was compared by Mann-Whitney U test, and the relationship between insulin-resistance and hs-CRP in patients group was analyzed using Spearman correlation analysis.@*Results@#(1)The levels of C-peptide (2.53(2.06, 3.23)ng/ml vs 2.24(1.89, 2.87)ng/ml), insulin (7.68(4.66, 11.97)μIU/ml vs 7.02(4.31, 9.59)μIU/ml) and HOMA-IR (1.75(1.09, 3.07) vs 1.57(0.97, 2.22)) in the patient group were significantly higher than those in the control group(all P<0.05). (2) The levels of HOMA-IR( 1.91(1.21, 3.74) vs 1.70(1.02, 2.72)) in patients with high hs-CRP(≥3 mg/L) was higher than those in the patients with low hs-CRP(<3 mg/L)(P<0.05). (3)Spearman correlation analysis showed that HOMA-IR was positively correlated with plasma hs-CRP level in the patient group (r=0.139, P<0.05). (4)After logarithmic transformation of related variables, multivariate linear regression analysis showed that HOMA-IR was linearly correlated with hs-CRP level and boy weight index.@*Conclusion@#The hs-CRP level in chronic schizophrenia has a positive predictive effect on insulin resistance.Detection of hs-CRP level in schizophrenic patients is helpful to assess metabolic risk of insulin.

Objective To explore the relationship between insulin resistance and plasma hypersen-sitive reactive protein (hs-CRP) in patients with chronic schizophrenia. Methods A total of 247 inpatients with chronic schizophrenia ( patient group) and 166 cases of normal individuals( control group) were en-rolled. Their general demographic and clinical data were collected,fasting blood glucose,hs-CRP,c-peptide and insulin indexes were tested,and insulin resistance index (HOMA-IR) was calculated. The insulin resist-ance level of the patients group and the control group was compared by Mann-Whitney U test,and the rela-tionship between insulin-resistance and hs-CRP in patients group was analyzed using Spearman correlation a-nalysis. Results (1)The levels of C-peptide (2. 53(2. 06,3. 23)ng/ml vs 2. 24(1. 89,2. 87)ng/ml), in-sulin (7. 68(4. 66,11. 97)μIU/ml vs 7. 02(4. 31,9. 59) μIU/ml) and HOMA-IR (1. 75(1. 09, 3. 07) vs 1. 57(0. 97,2. 22)) in the patient group were significantly higher than those in the control group( all P<0. 05). ( 2) The levels of HOMA-IR( 1. 91( 1. 21,3. 74) vs 1. 70(1. 02,2. 72)) in patients with high hs-CRP(≥3 mg/L) was higher than those in the patients with low hs-CRP (<3 mg/L) (P<0. 05). ( 3) Spearman correlation analysis showed that HOMA-IR was positively correlated with plasma hs-CRP level in the patient group (r=0. 139,P<0. 05). (4)After logarithmic transformation of related variables,multivariate linear regression analysis showed that HOMA-IR was linearly correlated with hs-CRP level and boy weight in-dex. Conclusion The hs-CRP level in chronic schizophrenia has a positive predictive effect on insulin re-sistance. Detection of hs-CRP level in schizophrenic patients is helpful to assess metabolic risk of insulin.
ABSTRACT
Objective@#To investigate the effects of long-term exposure to silica dust on serum CC16 and KL-6 levels.@*Methods@#The patients with stage I silicosis who were hospitalized in our hospital from April 2016 to April 2017 were treated as silicosis group. The silica dust exposed workers without silicosis who were taken the physical examination in our hospital were taken as a dust-exposed group. The healthy control group comes from in the same period of community physical examination did not touch the dust. The levels of CC16 and KL-6 in serum of all subjects were determined by enzyme-linked immunosorbent assay (ELISA) , and the levels of CC16 and KL-6 in serum were compared in three groups.@*Results@#Compared with the control group, the serum levels of CC16 in the silicosis group (P<0.01) and the dust-exposed group (P<0.01) were significantly lower. Compared with the control group, the level of serum KL-6 in the silicosis group was significantly decreased (P<0.01) compared with the control group, while the level of KL-6 in the serum of the dust-exposed group was significantly increased (P<0.01) . The ROC area of CC16 for diagnosis of silicosis was 0.92 (P<0.01) , with a sensitivity of 81.37%, specificity of 92.63% and Kappa value of 0.74.@*Conclusion@#Long-term exposure to silica dust may lead to a decrease in serum CC16 levels. Reduced serum CC16 levels may be useful in identifying the diagnosis of silicosis.
ABSTRACT
Objective@#To investigate the reproductive health status of female workers in the machinery industry and to analysis the effect of workload on their reproductive health.@*Methods@#5 732 female mechanical workers were selected and investigated by the Female Workers' Reproductive Health Questionnaire, which was printed by the occupational health and poisoning control institute of China CDC to collect the information about the reproductive health status of from March to December in 2016.@*Results@#The rate of abnormal menstruation was 27.15%, and the rate of gynecological diseases of female workers was 34.39%. The menstruation abnormality and gynecological diseases rate of female workers with high workload was higher than that female workers with low workload (both P<0.01) . High workload was the independent the risk factor associated with the menstruation abnormality (OR=1.88, 95%CI: 1.54~2.31, P<0.01) and gynecological diseases (OR=1.97, 95% CI: 1.61~2.40, P<0.01) .@*Conclusion@#The workload has a large impact on the reproductive health status of female workers.
ABSTRACT
OBJECTIVE To investigate the correlation between serum vitamin D levels and clinical efficacy of nasal endoscopic surgery for patients with chronic rhinosinusitis with nasal polyps(CRSwNP).METHODS Forty patients with CRSwNP were enrolled in this study,and were randomly divided into experimental group and control group.The experimental group were treated with VD(800 IU) plus budesonide nasal spray,and the control group was only given budesonide nasal spray for 8 weeks.Serum levels of 25-hydroxyvitamin D were measured before and after the experiment.Lund-Kennedy score,SNOT-20 and VAS were recorded.RESULTS Eighty percent of patients had VD deficiency (＜50 nmol/L)before treatment.The difference of VD level between the 2 groups was statistically significant after treatment.There was no significant difference in the scores of olfactory disorder between the 2 groups.The scores of SNOT-20 and Lund-Kennedy scores between the experimental group and the control group were statistically significant.CONCLUSION In patients with CRSwNP,the serum vitamin D levels are generally low,the clinical supplement to patients with vitamin D can significantly increase the serum levels of 25-hydroxy vitamin D,improve clinical symptoms and clinical effect of comprehensive treatment.
