Objective To evaluate the theraputic effect of transcatheter arterial chemoembolization (TACE)for hepatocellular carcinoma with tumor thrombosis of portal vein.Methods One hundred and six patients of hepatocellular carcinoma with tumor thrombosis of portal vein under treament of TACE were observed before and after the procedure.Results After TACE tumor size reduced＞50% in 23 patients,＜50% in 25, no significant change in 44.The size of tumor enlarged in 12.The disappearance of portal vein tumor thrombosis accessed in 14,with reduction in 39,and no significant change in 51.Two patients died within one week.Conclusion TACE provides good therapeutic effect on hepatocellular carcinoma with tumor thrombosis of portal vein.

Objective The levels of Thl cytokines(IL-10 and IL-13)and Th2 cytokines(INF-? and TNF-?)were determined in the sera of patients with Schistosomiasis japonica in order to find the relationship between cytokines and severe hepatic fibrosis(HF)in schistosomiasis.Methods A total of 358 patients with advanced Schistosomiasis japonica were examined by ultrasound.68 HBsAg negative patients were chosen randomly as experimental control.Among them,39 patients were found to have mild HF and 29 were severe HF.The sera levels of Thl and Th2 cytokines were determined with ELISA.Results Among these 358 patients,83(23.2%)were HBsAg positive.Neither earlier nor severer hepatic fibrosis was noted in the patients who had been simultaneously infected with HBV than those only infected with schistosomiasis. There was a significant difference between mild[ 1.60(1.30-12.14)ng/L]and severe[ 4.20(1.43- 52.07)ng/L]HF patients in the level of IL-10(Z=-3.907,P0.05)was found in level of IFN-?,between severe[3.12(1.38-66.14)ng/L]and mild[5.87(1.33-216.33)ng/ L]HF subjects.Our observation did not reveal any obvious difference of TNF-? between severe[ 2.48(0.79 -19.86)ng/L]and mild[ 2.28(0.67-15.72)ng/L]HF groups.Conclusions Patients infected with advanced shistosomiasis may become more susceptible to HBV.The results of the present investigation showed that a high level production of IL-13 was associated with severe HF.

OBJECTIVEBrain natriuretic peptide (BNP) levels are elevated in patients with atrial fibrillation (AF). The aim of this study is to investigate the relation between the pre-procedural BNP level and the incidence of recurrence AF after circumferential pulmonary vein ablation (CPVA).

METHODSPlasma BNP level was measured before CPVA in 69 consecutive symptomatic paroxysmal AF (PAF) patients without heart failure symptom. Atrial thrombus was detected by transesophageal echocardiography in 15 patients and CPVA was not performed in these patients. CPVA was successful in the remaining 54 patients and followed up for 3 months. All patients were asked to keep a log of the duration and frequency of their symptoms and underwent 24 h ECG monitoring at least once per month after the ablation.

RESULTSAt the end of follow up, 39 patients were free of AF recurrence (successful group) and 15 patients experienced AF recurrence (failure group). BNP concentration was below the heart failure range (< 500 ng/L) in 69.6% patients, but exceeded the normal range (0 - 144 ng/L) in 59.4% patients. Median baseline BNP level was significantly higher in failure group than in successful group (371.6 ng/L vs. 97.4 ng/L, P = 0.001). Left atrial (LA) dimension was also larger in failure group than in successful group [(53.3 ± 15.1) mm vs. (45.2 ± 11.2) mm, P = 0.036]. Moreover, BNP level was positively correlated with LA dimension (r = 0.574, P < 0.01).

CONCLUSIONThe pre-procedural BNP level and LA dimension are predictive of successful CPVA for PAF patients.

OBJECTIVETo determine the concentrations of interleukin-18 (IL-18), IL-6, IL-8, and prostaglandin E2 (PGE2) in the synovial fluid in patients with osteoarthritis (OA), and explore the role of IL-18 in the pathogenesis of OA.

METHODSThe synovial fluid was collected from 30 patients with knee OA, and the concentrations of IL-18 and the other cytokines were measured using enzyme-linked immunosorbent assay (ELISA). A linear regression was performed between IL-18 and the other cytokines.

RESULTSThe average IL-18 and PGE2 concentrations were 220-/+304 pg/ml and 89-/+104 pg/ml in the synovial fluid, respectively, and the two cytokines showed a positive correlation in the synovial fluid (r=0.628, P=0.001). The IL-18 concentration was also correlated to the concentrations of IL-6 (1200-/+1587 pg/ml, n=22; r=0.590, P=0.008) and IL-8 (5190-/+6024 pg/ml, n=9; r=0.776, P=0.014).

CONCLUSIONIL-18 can promote PGE2 production, which causes cartilage degradation in OA, thus therapies targeting this cytokine may prove an effective approach to early OA treatment.

OBJECTIVETo determine the effect of tension relaxation by small needle knife on the muscle tension and morphology changes of nerve terminals when sustained pressure was applied to muscular tissue.

METHODSRat gracilis muscles were exposed to pressure in vivo at 70 kPa for 2 hours. Sixty rats were divided into three groups: normal, control and experiment group respectively. In all rats except the six normal ones, the lower legs were considered as the control group, and the right left as experiment group. At day 1, 2 and 3, 9 rats from the two groups were randomly selected and sacrificed in order to determine the muscle tension change. At the same time, muscle histology and morphology changes of nerve terminals were observed.

RESULTSAbnormal tension increased in muscles under compression of 70 kPa. At the 1st and 2nd days, there were no significant differences between the two groups. Compared with control group, the tension was lower in experiment group, and there was statistically significant difference (P < 0.01) between the two groups. Exposure of striated muscle tissue to intensive and prolonged compression may pathologically alter its microstructure. Histological evaluation showed that this stiffening accompanied extensive necrotic damage. The changes could not be found in the nerve terminals.

CONCLUSIONDeep muscle tissue that undergoes prolonged compression may significantly increase its stiffness during acute injury. Tension relaxation applied by small needle knife can effectively reduce the mechanical load which is harmful to the whole tissue.

OBJECTIVETo evaluate the therapeutic effects of knife needle on third lumbar transverse process syndrome.

METHODSFrom 2007.3 to 2007.12, patients were divided into treatment group and control group according to the random digits table, 34 and 35 patients respectively. Patients in both groups were separately treated for 3 weeks, with knife needle in treatment group and electroacupuncture in control group. In treatment group, 12 patients were male and 22 patients were female, the average age was (42.33 +/- 7.86) years. In control group, 16 patients were male and 19 patients were female, the average age was (44.73 +/- 10.34) years. The changes of biomechanics, local tension and tenderness index were observed and recorded respectively before and after the therapy, and the results obtained from two groups were then compared with each other. The JOA score was used to evaluate the clinical effect.

RESULTSSixty patients finished the clinical observation. The treatment efficacy was evaluated according to the JOA score in 60 cases. The soft tissue tension in treatment group was lower than that in the control group (P=0.00004). Excellent result was found in 18 cases, good in 9 cases, fair in 3 cases and poor in 0 case.

CONCLUSIONTension relaxation by needle knife can effectively improve the clinical symptoms and signs of third lumbar transverse process syndrome.
