Objective To evaluate the clinical efficacy and safety of endovascular treatment for intracranial venous sinus thrombosis based on individual condition. Methods Twelve patients with intracranial venous sinus thrombosis were treated with endovascular management according to the severity and course of disease after they failed to respond to anticoagulant therapy. The clinical signs and symptoms,cerebrospinal fluid pressure and arteriovenous circulation time were observed and followed up (including MRV). Intravenous thrombolysis and mechanical thrombus maceration were carried out in all 12 patients,while intravenous thrombolysis, mechanical thrombus maceration in combination with intra-arterial thrombolysis were employed in 3. After the treatment, anticoagulant therapy was carried out for 6 months.The patients were followed up for 12 to 24 months. Results Of the twelve patients, clinical signs and symptoms included slight headache (2 cases), mild hemiplegia (1 case), ambiopia or blurred vision (3 cases). The cerebrospinal fluid pressure returned to under 26 cm H2O (1 cm H2O =0.098 kPa)following treatment from 28 to 38 cm H2O [ mean (32. 4 ±3.0) cm H2O] in preoperative measurement and the arteriovenous circulation time returned to below 10 s in all patients following treatment. Neither recurrence of thrombosis nor new symptoms of neurologic dysfunction was observed. No procedure-related intracranial or systemic hemorrhagic complications occurred both during and after the operation with the exception of a subcutaneous bleeding at the venopuncture site. Conclusion Endovascular treatment is effective and safe for patients with intracranial venous sinus thrombosis.

T site polymorphism is closely related to CHD and elevated serum triglyceride and total cholesterol.

OBJECTIVETo study the effect of job psychological demands and job control on mental health and their interaction.

METHODS93 male freight train dispatchers were evaluated by using revised Job Demand-Control Scale and 7 strain scales. Stepwise regression analysis, Univariate ANOVA, Kruskal-Wallis H and Modian methods were used in statistic analysis.

RESULTSKruskal-Wallis H and Modian methods analysis revealed the difference in mental health scores among groups of decision latitude (mean rank 55.57, 47.95, 48.42, 33.50, P < 0.05), the differences in scores of mental health (37.45, 40.01, 58.35), job satisfaction (53.18, 46.91, 32.43), daily life strains (33.00, 44.96, 56.12) and depression (36.45, 42.25, 53.61) among groups of job time demands (P < 0.05) were all statistically significant. ANOVA showed that job time demands and decision latitude had interaction effects on physical complains (R(2) = 0.24), state-anxiety (R(2) = 0.26), and daytime fatigue (R(2) = 0.28) (P < 0.05). Regression analysis revealed a significant job time demands and job decision latitude interaction effect as well as significant main effects of the some independent variables on different job strains (R(2) > 0.05).

CONCLUSIONJob time demands and job decision latitude have direct and interactive effects on psychosomatic health, the more time demands, the more psychological strains, the effect of job time demands is greater than that of job decision latitude.

OBJECTIVETo explore the relationship between the occupational stress and cardiovascular disease risk factors.

METHODSThe subject was 93 male freight train dispatchers, the occupational stressors, personalities, and occupational strain response were measured by using questionnaires. Blood pressure, heart rate, the concentrations of the cholesterol, triglyceride, and glycosylated hemoglobin in blood serum were also measured.

RESULTSSocial support score were significantly positively related to systolic pressure (r = 0.22) and diastolic pressure (r = 0.30) (P < 0.05), while job satisfaction negatively related to them and concentration of triglyceride (r = -0.37, -0.47 and -0.28 respectively, P < 0.05, P < 0.01), and self-esteem negatively to systolic pressure (r = -0.21, P < 0.05). The differences in diastolic pressure [(78.5 +/- 13.1), (83.6 +/- 8.2), (88.1 +/- 12.3), (85.8 +/- 9.8) mm Hg, P < 0.05] among groups of social support score, body mass index (BMI) (P < 0.01) among groups of job difficulty the differences in systolic pressure [(124.9 +/- 14.4), (129.7 +/- 13.1), (118.4 +/- 16.4), (133.5 +/- 23.1) mm Hg] and diastolic pressure [(85.5 +/- 11.3), (87.0 +/- 9.8), (80.1 +/- 10.1), (88.9 +/- 12.0) mm Hg] and cholesterol level in serum [(4.96 +/- 1.18), (5.39 +/- 0.85), (5.00 +/- 1.15), (4.34 +/- 0.91) mmol/L] among groups of vulnerability to stress (P < 0.05), as well as the difference in systolic pressure and glycosylated hemoglobin level in serum among groups of competition score (P < 0.05) were all statistically significant. Stepwise regression analysis showed that job time demands and negative coping affected the change of cholesterol (R(2) > 0.05); the job relation decision latitude, social support, job difficulty, personality (self-esteem and anxiety trait) and negative coping were the predictors of smoking (R(2) > 0.05). Heart rate was related to home income and competition factor of Type A Behavior (R(2) = 0.06).

CONCLUSIONThe psychosocial stress aspects of work may be related to some cardiovascular risk factors.

OBJECTIVETo investigate the association of -1131T>C and c.553G>T polymorphisms and their haplotypes in apolipoprotein A5(ApoA5) gene with cereberovascular disease in Chinese.

METHODSUsing polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), we analyzed two ApoA5 genetic variants in 272 patients with cerebral infarction (CI) and 316 control individuals respectively. The levels of serum lipid profiles were measured with biochemical methodsìand the other clinical characters were obtained by case file investigation.

RESULTSThe odds ratio (OR) for CI in -1131CC genotype carriers was 2.10 (95%CI 1.01-4.37). The distribution of T-T and T-G haplotypes had obvious differences between CI patients and control individuals. The OR for CI in C-G and T-G haplotype carriers were 1.34 and 0.71(95% CI 1.02-1.76 and 0.55-0.92) respectively, compared with the others. Furthermore, the major haplotypes had significant differences of serum TG(P< 0.05).

CONCLUSIONThe ApoA5 -1131T>C polymorphism may be associated with an increased risk of CI in the Chinese population, but the influence of blood lipids can not be ignored.

OBJECTIVETo evaluate the therapeutic effect of combined CT-guided percutaneous radio-frequency ablation (RFA) plus percutaneous ethanol injection (PEI) on nonresectable priminary hepatocellular carcinoma (HCC) after transcatheter arterial chemoembolization (TACE).

METHODSOne hundred fifty patients diagnosed as HCC either by pathology or by AFP combined with typical CT and angiographic image findings were studied, 99 men and 51 women, with an average of 51 years. Each patient had at least 3 lesions, ranging from 3.1 to 7.9 cm in diameter, average 5.0 cm. All patients were randomly divided into group A (control group) and group B (combination group) according to their check-in date (odd or even). In group A, 74 patients were treated with RFA alone two weeks after TACE. In group B, 76 patients were treated with RFA plus PEI two weeks after TACE.

RESULTSThe complete necrosis rate was 75.8% in group A and 89.5% in group B (P < 0.05).

CONCLUSIONThe clinical therapeutic effect of radiofrequency ablation (RFA) combined with percutaneous ethanol injection (PEI) is better than that of RFA alone after TACE in HCC.

AIMTo prepare a new oral colon-specific delivery formulation and to investigate the release profile in vitro and the colon-specific delivery property in vivo in dogs.

METHODSSodium 4-aminosalicylic acid was selected as the model drug. The combination of Eudragit RL30D and RS30D were used as sustained-release film, and Eudragit FS30D used as enteric film, which was expected to release drug depending on pH and time. The release profile of tablets was studied in three phosphate buffers with the pH 6.5, 7.0 or 7.4 for 12 h after a simulated gastric presoak for 2 h in 0.1 mol x L(-1) HCl. The tablets were radiolabelled with 99mTc to make their release times and positions in the gastrointestinal tract be followed using a gamma camera.

RESULTSFor the in vitro study, there was no drug released in 0.1 mol x L(-1) HCl for 2 h, and release occurred slowly when pH was above 6.5. Drug was released faster while pH was higher. For the in vivo study, the coated tablets remained intact in the upper gastrointestinal tract, and drug release began after the colonic arrival. The uncoated tablets, however, disintegrated in the stomach of the dogs rapidly.

CONCLUSIONThe coating could protect the drug until the tablets reached the ascending colon, where drug was released slowly for over 10 h.
