Objective: To observe the clinical effect of integrated traditional and western medicine in treating chronic idiopathic thrombocytopenic purpura (CITP) elderly patients. Methods: Sixty patients were divided randomly into the treatment group (n=30) and the control group (n=30), the former was treated with danazol combining with prednisone and Chinese drugs, while the latter was treated with VCR. Results: The total effective rate of the treatment group was better than that of the control group, the difference between those two groups was significant (P

[Summary] The HK-2 cells with different culture media were divided into normal glucose group (NG group,5.5 mmol/L D-glucose) ; high glucose group (HG group,30 mmol/L D-glucose) ; mannitol group (MG group,5.5mmol/L D-glucose+24.5 mmol/L mannitol) ; 1,25-dihydroxyvitamin D3 [1,25-(OH)2D3] groups (V1-V3 group)which were exposed to medium containing 30 mmol/L D-glucose and different concentrations of 1,25-(OH)2D3 ;Nethyl-cysteim control group (NAC group,30 mmoL/L D-glucose + 1.0 mmol/L N-Nethyl-cysteim) ; and ethanol control group(SG group,30 mmol/L D-glucose+6.86 × 10-2 mol/L ethanol).The level of intracellular reactive oxygen species,mitochondrial membrane potential,activity of total-superoxide dismutase (T-SOD),level of malondialdehyde,expression of UCP2 mRNA and protein in HK-2 cells were detected.Compared with NG group,the mitochondrial membrane potential significantly decreased in HG group (P＜0.01),and the mitochondrial membrane potential in V group was lower than that in HG group(P＜0.01).The activity ofT-SOD in HG group was significantly lower than that in NG group(P＜0.01),while its level of malondialdehyde was significantly higher than that in NG group(P＜0.01).Compared with HG group,the activity of T-SOD in V groups was significantly increased (P＜0.05)and the level of malondialdehyde in these groups significantly decreased (P＜0.01).The mRNA expression of UCP2 in HG group was increased significantly in comparison with NG group (P ＜ 0.05) and the expression in V groups was significantly decreased in comparison with HG group (P＜0.01).The results suggest that 1,25-(OH)2D3 could reduce the mitochondrial membrane potential,the production of reactive oxygen species,and regulate the expression of UCP2 in order to suppress the oxidative stress induced by high glucose.

OBJECTIVETo investigate the effect and safety of extracorporeal shock wave (ESW) in the treatment of pain symptom of type III B prostatitis.

METHODSWe treated 50 cases of type III B prostatitis by ESW once a week for 4 weeks. Then we evaluated the clinical effect and safety of the therapy based on the NIH-CPSI scores, visual analogue scale (VAS) scores, IIEF-5 scores, prostate volume and morphous, state of urination, color of urine, results of routine semen analysis, and changes of cytokines (IL-6, TNF-α and IL-1β) in expressed prostatic secretion (EPS).

RESULTSAll the patients successfully accomplished the treatment. Compared with the baseline, decreases were observed after 4 weeks of cytokine treatment in the pain scores (14. 61 ± 1. 82 vs 9. 36 ± 1. 47, P <0. 01), urination symptom scores (4. 59 ± 1. 01 vs.4. 66 ± 0. 89, P >0. 05) , quality of life scores (6. 51 ± 1. 03 vs 4. 56 ± 1. 02, P <0. 01), NIH-CPSI (25. 43 ± 1. 72 vs 18. 28 ± 2. 32, P <0. 01 ), and VAS (6. 59 ± 1. 10 vs 3. 02 ± 1. 07, P < 0. 01). The concentration of IL-6 in the EPS was significantly increased ([55.82 ± 6. 28] vs [86.59 ± 4. 55] ng/ml, P <0. 01) , while the level of TNF-α ([3.89 ± 0. 12] vs [3. 19 ± 0.22] ng/ml, P<0.01) and that of IL-1β ([3.21 ± 1.01] vs [1.48 ± 0.95] ng/ml, P< 0. 01) remarkably reduced after treatment. However, there were no statistically significant differences in IIEF-5 scores (18. 58 ± 2. 03 vs 18. 51 1. 89, P >0. 05) or various sperm parameters before and after treatment (P >0. 05). And no significant changes were observed in the prostate volume, morphous or internal echoes.

CONCLUSIONThe ESW therapy is effective and safe for the pain symptom of type III B prostatitis.

ObjectiveTo provide evidence for the development of national norm of coping style for petrol station employee.MethodsStratified random sampling surveys and individual interview were performed in 13 269 in-service petroleum employees.Taking gender,age,education level and marriage as independent variables and coping factors as dependent variables,t test or analysis of variance was completed.Results Our data indicated that coping style was significantly changed in different gender ( P＜0.05),age (F=4.596,P＜0.05),education (F=14.723,P＜0.05) and marriage groups (P＜0.05).Conclusion Specified working environment results in corresponding coping style,and the development of national norm may be important and necessary.

Objective To establish symptom check list 90 (SCL-90) norm for Chinese oilmen.Methods Based on multi-level stratified or cluster sampling technique,a total of 13 472 oilmen from China National Petroleum Corporation completed a sampling survey on measured data of SCL-90.Student's t test and one-way analysis of variance (ANOVA) were used to compare gender,age,education level and marriage status.Results All the reliability coefficients were ＞ 0.8 and P for validity test was ＜ 0.05.In comparison with SCL-90 norm of healthy Chinese adults in 1986,the interpersonal sensitive (1.5 ± 0.6)and paranoia (1.4 ± 0.6) of oilmen were lower (t≤-4.17,both P ＜ 0.05),although other 8 factors showed higher scores (t ≥ 2.4,all P ＜ 0.05).Oilmen also had lower scores for each item than Chinese army men (t ≤-2.62,all P ＜ 0.05).Total score (131.4 ± 47.7),interpersonal sensitive (1.4 ± 0.6),hostility (1.5 ± 0.6),paranoia (1.4 ± 0.6) and psychosis (1.3 ± 0.5) of females were lower than those of males (t≥2.53,all P ＜ 0.05).30-39 years group indicated the highest scores for each item (all P ＜0.05),while 17-29 years group got the lowest (all P ＜ 0.05).Meanwhile,the subjects whose education level was equate to or lower than high school or those got married were found to have the highest scores (all P ＜ 0.05).Conclusions Our data show better item differentiation,reliability and validity of SCL-90.SCL-90 norm may be used for mental health assessment of Chinese oilmen.

Objective: To prepare self micro-emulsifying drug delivery system (SMEDDS) of tectorigenin (TG), and investigate its dissolution. Methods: The formulation was optimized using Design Expert based on D-optimal design. The microemulsion's physicochemical and in vitro dissolution were evaluated after self-microemulsification. Results: The particle size and Zeta potential of the final formulation were (14.95 ± 0.31) nm and (-12.53 ± 0.80) mV after it was diluted by 10 times with pure water. The microemulsion appeared to be spheres with homogeneous size, which can be observed through a transmission electron microscope. The drug loading capacity was 20 mg/g, and the average content was (99.03 ± 0.70)%. The results of in vitro dissolution study showed that the accumulative dissolution could be close to 100% after 10 min in both hydrochloric acid solution (pH 1.2) and PBS (pH 6.8). Conclusion: D-optimal design could be used to optimize the formulations of TG-SMEDDS successfully. The TG-SMEDDS exhibits a larger accumulation dissolution than TG. This formulation would be easier absorbed through gastrointestinal tract compared to TG. The results of this study are expected to offer data support and reference for the TG's formulation design and clinical application.

AIM: To examine expression of macrophage migration inhibitroy factor (MIF) gene and protein in macrophages induced by oxidized low density lipoprotein (ox-LDL). METHODS: Macrophages were incubated with ox-LDL at the concentration of 150 mg/L for time course (0-36 h) and with ox-LDL at the different concentrations (0-300 mg/L) for 24 h, expression of MIF mRNA and protein were detected by RT-PCR and ELISA. RESULTS: The results showed that ox-LDL increased MIF gene and protein expression in macrophages in a dose and time-dependent manner. After the exposure of macrophage to ox-LDL, the expression of MIF mRNA level increased consistently with protein. CONCLUSION: MIF may play an important role in atherosclerosis. [

This study is designed to obtain recombinant human acetylcholinesterase (rhAChE) and apply it in screening acetylcholinesterase inhibitors. The rhAChE was overexpressed in HEK293 cells transfected by plasmid of pCMV-AChE with the cationic liposome and rhAChE was found to be secreted into cell culture medium. AChE activity was assayed according to modified Ellman method to obtain kinetic parameters. IC so50 values for donepezil compounds of rhAChE were calculated to determine their activities of inhibition. The results showed that Km value was 151.9 micromol.L-1 donepezil inhibited rhAChE in a mixed competitive-noncompetitive way (Ki= 16.03 nmol.L-1, Ki = 18.36 nmol.L-1) and that most new compounds tested exhibited high activities of inhibition on rhAChE. The study suggests that rhAChE is available to be applied in screening AChE inhibitors in vitro.
