Objective To investigate the therapeutic effect and mechanism of ribavirin to mice viral myocarditis. Methods Onehundred and twenty mice were randomly divided into 3 groups. Group 1 was normal control group 1 .group 2 CVB3 control group, group 3 ribavirintherapy group. In the latter two groups, 0.2 mL CVB3(10-7.5Tcid5o/mL)was infected into abdominal cavity. Ten mice of each group were killed at the 7 th, 14 th,21 st,28 th day. Mice motality,light and electron microscape, myocardial viral tiler, myocardial pathological score,serum cTnI,malonytdialdehyde(MDA) and cardiac myocyte apoptosis rate(CMAR) were examined.Re-sults The motality,myocardial viral titer,myocardial pathological score,cTnI were lower in group 3(ribavirin therapy group) than in group 2(CVB3 control), and MDA and CMAR were no significant differences between ribavirin group and simple CVB3 group. Conclusion Ribavirin has good treatment effect to mice viral myocardilis,and its mechanism is due to decrease viral titer.

OBJECTIVETo explore the effect of Xinfeng Capsule (XC) on lipoprotein metabolism of rheumatoid arthritis (RA) patients.

METHODSTotally 180 RA patients were assigned to the experimental group and the control group by random digit table, 90 in each group. Patients in the experimental group took XC (three pills each time, three times daily), while those in the control group took Methotrexate Tablet (four tablets each time, once per week). One month consisted of one therapeutic course and all patients were treated for two therapeutic courses. A healthy control group consisting of 60 patients was also set up. Changes of lipoprotein indices, clinical efficacy, lipid metabolism, joint symptoms and signs, activity indicators were observed, and correlation analyses were performed.

RESULTSCompared with the healthy control group, expression levels of prealbumin (PA), globulin (GLO), high-density lipoprotein (HDL), apolipoprotein Al (Apo-A1) were lowered in RA patients (P <0. 05, P <0. 01). Correlation analyses showed that PA was negatively correlated with joint tenderness, morning stiffness time, disease activity score (DAS-28), C-reactive protein (CRP), interleukin (IL)-6, respectively. Total protein (TP) was negatively correlated with joint tenderness. GLO was negatively correlated with joint tenderness and DAS-28. HDL was negatively correlated with erythrocyte sedimentation rate (ESR) and endothelin (ET)-1. Apo-Al was negatively correlated with joint pain; Apo-B was negatively correlated with CRP; LDL was negatively correlated with morning stiffness time (P <0. 05, P <0. 01). Compared with before treatment, expression levels of PA, HDL, Apo-A1 , Apo-B, and serum IL-10 contents increased, and expression levels of ESR, CRP, IL-6, ET-1 , joint pain, joint swelling, morning stiffness time, and DAS-28 decreased in the experimental group (P <0. 05, P <0. 01). PA increased more after treatment than before treatment in the control group (P <0. 01). There was statistical difference in joint symptoms (except joint tenderness) and activity indices (except ET-1) in the control group (P <0. 05, P <0. 01). Compared with the control group after treatment, PA and HDL increased, ET-1 and duration of morning stiffness decreased in the experimental group (all P <0. 05).

CONCLUSIONSLipoprotein metabolic disorder exists in RA patients, and it is associated with disease activity. XC could obviously improve lipoprotein metabolism and joint symptoms.

OBJECTIVETo explore the application of liposuction in scar repair.

METHODSLiposuction using tumescent technique was performed at the scar region. While the local skin was relaxed and tension decreased, scar resection and wound closure followed. The indications and key points of this operation are discussed in the article.

RESULTSThis method has been used in 27 patients for scar repair since 2000. The biggest area of excised scar was 40 x 9.5 cm. The width of the excised scar reached 11 cm. All the patients got satisfactory results.

CONCLUSIONThe operation was simple and safe with little blood loss. After liposuction, a larger area of scar at a fatty region could be excised, and meanwhile, body sculpture was achieved.

OBJECTIVETo observe the effect of combined therapy of Neiyi pill (NP) and Neiyi enema (NE) on endometriosis and its effect on serum levels of endometrial antibody (EMAB) and carcinoembryonic antigen 125 (CA125).

METHODSFifty-eight cases with endometriosis were divided into 3 groups randomly, group A (n = 16) treated by NP, group B (n = 24) treated by NP and NE, and group C (n = 18) treated by danazol, all for 3 menstrual cycle with single blind method. The effect was observed and the serum levels of EMAB and CA125 were detected before and after treatment.

RESULTSComparison of the efficacy between the 3 groups showed: there was no remarkable difference between group A and B (P >0.05), both of group A and group B were superior to that of group C (P<0.05). The levels of EMAB and CA125 had no significant changes in all the three groups after treatment.

CONCLUSIONCombined therapy of NP and NE could improve the curative effect on endometriosis, and without obvious effects on serum levels of EMAB and CA125.

OBJECTIVETo investigate the effect of infrasonic field of minesweeper on psychology of minesweeper crews.

METHODSAn experimental ship was selected to conduct infrasonic minesweeping, a control ship of the same type was selected to operate likewise with the infrasound generator turned off, and another group of coast-servicemen was chosen as blank control. Attention-span test, digit memory test, two-digital numbers list and profile of mood states (POMS) were used to test the ship crews and coast-servicemen.

RESULTSThere were no significant differences in psychological parameters between the two ship crews before the experiment. But the scores of two-digit figures list in ship crews were significant lower than that in coast-servicemen, (31.2 +/- 11.8, 36.4 +/- 14.5 respectively vs 45.8 +/- 13.9, P < 0.05). POMS showed that the scores of anger-hostility, fatigue-inertia, and confusion-bewilderment in both ship crew groups [(15.5 +/- 6.4, 18.3 +/- 6.8), (12.1 +/- 5.0,12.3 +/- 4.9), (11.6 +/- 4.4, 12.5 +/- 4.8), respectively] were higher than those in coast-servicemen (13.9 +/- 7.0, 7.6 +/- 4.1, 8.2 +/- 4.3, respectively, P < 0.05 or 0.01), while vigor-activity in experimental group (15.0 +/- 5.9) was lower than that in coast-servicemen (19.7 +/- 4.7). After the experiment, the scores of experimental crews in digit memory test (14.5 +/- 5.0), vigor-activity (12.2 +/- 5.8), fatigue-inertia (15.8 +/- 6.2) were significantly different from those of control crews (17.3 +/- 4.8, 16.5 +/- 4.6, 11.3 +/- 5.1).

CONCLUSIONSThe infrasonic field from minesweeper may injure the crew's psychological health and some neurobehavioral function.

This study was aimed to investigate the effect of berberine on the proliferation and apoptosis of HL-60 cells, and the expression of vascular endothelial growth factor receptor 2 (VEGFR2) in HL-60 cells. Berberine (6 - 96 µg/ml) was added to the HL-60 cell line culture medium, the CCK-8 method was used to reveal the inhibitory effect on cell proliferation, the flow cytometry was used to determine the apoptosis rate and cell cycle in HL-60 cells treated with berberine. The expression of VEGFR2 mRNA and protein were examined by RT-PCR and Western blot respectively. The results showed that the berberine inhibited the proliferation of HL-60 cells and induced their apoptosis in dose- and time-dependent manners. With the increased concentration of berberine, the percentage of HL-60 cells in G(1) phase of cycle increased significantly, and the percentage of HL-60 cells in S phase decreased significantly. The expression of mRNA and protein of VEGFR2 decreased with the increased concentration of berberine. It is concluded that the berberine can inhibit HL-60 cell proliferation and induce HL-60 cell apoptosis. The expression of mRNA and proteins of VEGFR2 decreased after treatment with berberine.
