ABSTRACT
OBJECTIVES@#Due to the narrow therapeutic window of valproic acid (VPA), grievous adverse reactions such as hepatotoxicity, nephrotoxicity may occur in patients with epilepsy for a long time. This study aimed to explore the effect of VPA concentration on biochemical and routine blood test related to liver, renal, and hematology in epileptic outpatients treated with VPA alone or combined with other antiepileptic drugs.@*METHODS@#A total of 3 194 Chinese epileptic outpatients from Xiangya Hospital, were analyzed in a crude analysis after stratifying through dosage regimens. The plasma VPA concentration was detected by gas chromatography method and then standardized through dosage and body weight. Ten biochemical indexes related to liver, renal, and hematology were evaluated.@*RESULTS@#Of all patients, blood urea nitrogen (BUN), serum creatinine (SCr) level, and erythrocyte count (RBC) showed positive correlations with standardized VPA concentration (=0.494, =0.157, =0.596, respectively), while platelet specific volume (PCT) and blood platelet (PLT) showed negative correlations with standardized VPA concentration (=-5.500, =-0.086, respectively). After stratifying through dosage regimens, significantly positive associations between SCr and standardized VPA concentration were found in the juvenile patients from the monotherapy group and combination therapy group (=1.800, =0.352, respectively). In addition, PLT and leukocyte count (WBC) in the juvenile patients from the combination therapy group were negatively correlated with standardized VPA concentration (=-1.463, =-0.079, respectively), while RBC showed a positive association with standardized VPA concentration in the juvenile patients from the monotherapy group (=0.068).@*CONCLUSIONS@#SCr level is significantly associated with plasma VPA concentration. Drug combination and age are important factors leading to hematological disorders. The finding provides potential theoretical guidance for the rational and safe clinical use of VPA.

OBJECTIVE： To study the effects of exogenous methyl jasmonate on the contents of 4 kinds of secoiridoid substance （gentiopicrin， swertiamain， sweroside and amarogentin） and biochemical indexes in the leaves of Gentiana rigescens， and to provide scientific evidence for the application of methyl jasmonate in standardized planting of G. rigescens. METHODS： 2， 4， 6， 8， 10 d after spraying 10， 50， 100， 200 mg/L methyl jasmonate （spraying amount was 500 mL） for G. rigescens strain， the leaves of medicinal material were collected as sample， and the other leaves without spraying methyl jasmonate were collected as control. HPLC method was used to determine the contents of 4 kinds of secoiridoid substance in the leaves of G. rigescens after spraying 4 kinds of concentrations of methyl jasmonate for 10 d. The concentration of methyl jasmonate was optimized （the content of effective component was the highest）. HPLC method was adopted to determine the contents of 4 kinds of secoiridoid substance in the leaves of G. rigescens after spraying the optimal concentration of methyl jasmonate for different time. The levels of relevant biochemical indexes （SOD， POD， CAT， MDA） were determined. RESULTS： 10 d after spraying 10， 50， 100， 200 mg/L methyl jasmonate for G. rigescens strains， the contents of 4 kinds of secoiridoid substance in the leaves were increased to different extent. Compared with untreated leaves， 100 mg/L methyl jasmonate had the best effect after spraying， and the contents of gentiopicrin， swertiamain and sweroside in treated leaves were 1.88， 2.36 and 1.87 times of those in untreated leaves， respectively （P＜0.05）. 2， 4， 6， 8， 10 d after spraying 100 mg/L methyl jasmonate， the contents of 4 kinds of secoiridoid substance in treated leaves were higher than untreated leaves at corresponding stage； the content of secoiridoid had significant difference after spraying for 4 d （P＜0.05）. The contents of active components in general were relatively high after spraying for 6 d， and the contents of gentiopicrin， swertiamain， sweroside and amarogentin in treated leaves were 1.88， 1.88， 1.47， 1.82 times of those in untreated leaves， respectively （P＜0.05）. The levels of relevant biochemical indexes in treated leaves were increased significantly since 4 d of spraying， compared with untreated leaves （P＜0.05）. CONCLUSIONS： After spraying 100 mg/L methyl jasmonate for 6 d， the contents increase of 4 kinds of secoiridoid substance in the leaves of G. rigescens are most obvious， which may be associated with improving the levels of related biochemical indexes.
ABSTRACT
Objective To investigate the effects of 3 different blood purification methods with single treatment or continuous treatment for 2 months on the physiological and biochemical indexes of patients with maintenance of hemodialysis (MHD). Methods The clinical data of 90 patients who underwent MHD in Department of the Blood Purification of Wuhan General Hospital of PLA from March 2016 to April 2017 were retrospectively analyzed, and they were divided into three groups: hemodialysis (HD) group, hemodiafiltration (HDF) group and HD + hemoperfusion (HP) group, 30 cases in each group. All the patients were treated routinely with erythropoietin and iron, and original oral antihypertensive drugs were continuously taken. The patients in HD group underwent 3 times of HD each week, 4 hours each time; the patients in HDF group applied once HDF and twice of HD each week, once 4 hours, and post dilution method was adopted with the replacement volume 50 - 70 mL/min; the patients in HD+HP group performed once HD+HP and twice HD each week, 4 hours each time. The levels of blood creatinine (SCr), urea nitrogen (BUN), plasma leptin (LP), serum parathyroid hormone (PTH), serum hypersensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), etc. were collected before single dialysis, 4 hours and 2 months after continuous treatment, and the differences in above indexes were compared among the three groups. Results With the prolongation of dialysis time, renal function related indexes (SCr, BUN), macromolecular toxin related indexes (LP, PTH) and micro inflammation related indexes (hs-CRP, IL-6) in the three groups were significantly lower than those before dialysis, the degrees of decrease of the indexes after continuous treatment for 2 months were more obvious than those after single treatment for 4 hours, but there were no statistical significant differences in inter-group comparisons of SCr and BUN among the three groups (both P ＞ 0.05). After 2 months of continuous treatment, the degrees of decrease of LP, PTH and hs-CRP and IL-6 levels in group HD+HP were more significant than those in either HD group or HDF group [LP (ng/L): 7.56±2.67 vs. 9.55±3.67, 8.82±2.47, PTH (ng/L): 356.88±189.46 vs. 520.55±330.16, 487.43±234.26, hs-CRP (mg/L):10.30±3.21 vs. 21.43±4.46, 12.31±3.92, IL-6 (ng/L): 18.56±4.62 vs. 34.21±6.77, 19.84±6.41, all P ＜ 0.05]. Conclusion HD+HP can effectively improve the physiological and biochemical indexes of MHD patients, and is an ideal way to treat MHD patients.

ABSTRACT
Objective To explore the effects of dichloromethane(DCM)exposure on serum biochemical indexes among furniture manufacturing workers. Methods A total of 65 workers who engaged in adhesive operations in furniture manufactory and 56 workers who would be recruited into another factory as new employees were investigated. Twenty two pairs of workers were selected as occupationally exposure group and control group,respectively. The concentration of DCM in workplace of adhesive operations in furniture manufactory was determined. Serum levels of TP,ALB,GloB,A/ G, ALT,AST,GGT,AFU,GPDA,ADA,ALP,CHE,CHOL,TG,TBA,TBIL,DBIL and IBIL were tested by automatic biochemical analyzer in all groups. Results The mean levels of serum TP,ALB,GloB in exposure group( the concentrations of DCM in workplace were 1 300 - 7 760 mg/ m3 )were 73. 7 ± 3. 6,47. 5 ± 2. 3 and 26. 2 ± 2. 8 g/ L,which were significantly lower than that of control group(P < 0. 05). Compared to the control group,the mean levels of CHE, ADA,AST and ALT activity in exposure group(7 477. 8 ± 1 240. 8,7. 3 ± 1. 7,21. 6 ± 5. 6 and 13. 0 ± 5. 6 U/ L)were significantly lower(P < 0. 05). The mean levels of TBIL,DBIL and IBIL were 13. 9 ± 7. 6,6. 4 ± 4. 3 and 7. 5 ± 3. 4μmol/ L,respectively,which were significantly higher than that of control group(P < 0. 05). No significant difference in the mean levels of the other biochemical indexes in serum was observed between exposure and control group. However,no correlation was found between the levels of ALB and TBIL,ALB and DBIL,or ALB and IBIL. Conclusion Occupational exposure to DCM is associated with the decrease of TP,ALB,GloB and CHE levels in serum. Meanwhile,DCM occupational exposure is correlated with the increase of TBIL,DBIL and IBIL levels in serum. Our data suggest that occupational exposure to DCM may be related to inhibition of synthetic function in live,damage of blood cells and declined metabolism of bilirubin.

ABSTRACT
Summary: The influence of exercise at high temperature on adult males' routine blood indexes and biochemical indexes and the expression of HSP72 in peripheral blood lymphocytes (PBLs) was studied in order to provide theoretical ground for health supervision of adults receiving exercise at high temperature. 180 adult males were selected and divided into exercise group and control group, in which the exercise group was subdivided into subgroup 1 and subgroup 2 receiving exercise at high temperature in the afternoon and in the morning, respectively. Peripheral venous blood was phlebotomized before and after the exercise to examine routine blood indexes and blood biochemical indexes. The expression levels of HSP72 in PBLs were detected by flow cytometry. The results showed that the routine blood indexes and biochemical indexes in each group were within the range of normal values of male adults. There was no significant difference between each exercise group and control group in indexes before exercise. After exercise, the expression levels of HSP72 in PBLs in exercise groups were higher than those before exercise, and HSP72 expression levels'in subgroup 1 were obviously higher than those in subgroup 2 and control group. The contents of ALT, urea, Na+, Cl-, Ca2+and K+ in subgroups 1 and 2 were lower than those in control group, but CK level was higher than in control group (P<0.05). The contents of Na+ and Cl- in subgroup 1 were relatively lower than those in subgroup 2 (P<0.05). It was concluded that while receiving exercise at high temperature, adult males' HSP72 levels in PBLs could be increased and the biochemical indexes changed. Attention should be paid to health supervision to avoid obvious body injuries at high temperature.
