50Gy gave better survivals.Conclusion Age,tumor histology,ex- tent of resection,interval time of postoperative radiotherapy and the dosage of target were related to survival.

ObjectiveTo investigate the effect of speech therapy on mental health of patients with aphasia. MethodsCRRCAE and SCL-90 were used to assess the speech and mental state in 28 aphasia patients. All aphasia patients were treated by using speech therapy and the changes before and after treatment were compared. ResultsThe scores in listening comprehension, repetition, naming, reading,reading comprehension, writing and counting were distinctly higher at post-treatment than that at pre-treatment. All SCL-90 factor's levels at post-treatment were distinctly reduced than that at preat post-treatment(P<0.01).Conclusions Speech therapy can improve the language function,as well as mitigate the mental symptoms.

AIMTo increase the cognition of cerebellar functions and the knowledge of neuroimmunology, the effect of cerebellar interposed nuclei (IN), one of three deep nuclei in cerebellum, on lymphocyte function was investigated.

METHODSKainic acid (KA) was microinjected into bilateral IN for lesions of neuronal bodies in the IN. Control rats was microinjected with saline into their IN. On days 8, 16 and 32 following the IN lesions, the lymphocyte number in the peripheral blood was measured by blood corpuscle counter. Meanwhile, lymphocyte proliferation induced by concanavalin A (Con A), cytotoxicity of natural killer (NK) cells against YAC-1 cells, and anti-SRBC IgM antibody in the serum were examined respectively by methyl-thiazole-tetrazolium (MTT) assay, flow cytometry and ELISA assay.

RESULTSThe lymphocyte number in the peripheral blood was significantly reduced on days 8, 16 and 32 following the effective lesions of the bilateral IN in comparison with that of control. The Con A-induced lymphocyte proliferation, the NK cell cytotoxicity to YAC-1 cells, and the titer of anti-SRBC IgM antibody in the serum, were all significantly attenuated on days 8, 16 and 32 following the effective lesions of the bilateral IN in comparison with those of control. There were not remarkable differences between the days 8, 16 and 32 in the decreased lymphocyte number and functions induced by the lesions of the bilateral IN.

CONCLUSIONEffective lesions of the cerebellar bilateral IN of rats cause an inhibition in lymphocyte number and functions of T, B and NK cells, strongly showing that the cerebellar IN can modulate lymphocyte functions.

Objective To investigate the relationship between CYP2J2*7 mutation(G-76T) and coronary heart disease (CHD) in Chinese Hanpopulation and to study the effects of CYP2J2 geneover-expressionon the proliferation and migrationof aortic smooth muscle cells of ApoE-/- mice. Methods CYP2J2*7 genotype was detectedin 500 patients with CHD and 478 controlsubjects by the Polymerase Chain Reaction-Restriction Frag-ment Length Polymorphism (PCR-RFLP). Culturedaortic smooth muscle cells of ApoE-/- mice were divided into control group, sham transfectiongroup and CYP2J2 over-expression group. Cell proliferation and migration were investigated after CYP2J2 over-expressionby MTS and Transwell assay. Results The frequency of CYP2J2*7 in CHD group was significantly higher than that incontrol group (10.00% vs. 6.49%, P = 0.046). Same is the case in female cases(P = 0.026). Compared with these of aortic smooth muscle cells incontrol group and sham trans-fectiongroup, the cell proliferation in 24, 48, 72 h, and the cell migration in 48 h after CYP2J2 over-expression in CYP2J2 group were significantly suppressed. Conclusions CYP2J2*7 mutation might increase the risk of CHD in Chinese Han population. CYP2J2 over-expression can suppress the proliferation and migration of aortic smooth muscle cells and CYP2J2 might have the effect of anti-atherosclerosis.

Objective To investigate the clinical effect of vagus nerve preserving pericardial devascularization plus subtotal splenectomy in treating portal hypertension with a history of variceal bleeding.Methods The clinical data of 33 cases of portal hypertension with variceal hemorrhage treated with vagus nerve preserving selective pericardial devascularization plus subtotal splenectomy from April 2004 to December 2013 (study group) were compared with that of 34 cases treated with pericardial devascularization plus splenectomy (control group).Results There was no mortality in two groups.The postoperative gastric drainage during the first 72 h were(1 525 ±30) ml in the study group and (2 130 ±40) ml in control group(P ＜0.05).Portal vein thrombosis developed in one case in the study group and 15 cases in the control group(P ＜ 0.05).Postoperative 3-year recurrent gastroesophageal varices hemorrhage was 15％ in the study group and 25％ in the control group (P ＜ 0.05).Postoperative 5-year variceal hemorrhage recurrence rate were 28％ in the study group and 30％ in the control group (P ＞ 0.05).Conclusions Maitaining vagus nerve selective pericardial devascularization plus subtotal splenectomy is of less postoperative complication and lower portal vein thrombosis rate and better patients' survival compared with pericardial devascularizatim plus total splenectomy.

AIM: To study on antisense oligoncleotides as inhibitor of human acute promyelocytic leukemia (HL-60) proliferation and C-myc protein expression. 　METHODS: Oligonucleotides with different lengths (18-21 mer) complementary to the definite regions of C-myc mRNA, modified groups (with S replaced O in internucleotide phosphate linkage) and unmodified ones (with natural internucleotide phosphate linkage) were designed and synthesized. These olignucleotides were tested for their activity on HL-60 cell and also for their toxicity on normal lymphatic cells of human. 　RESULTS: It was found that two of the oligonucleotides complementary to 5′-44-61 and 5′-556-576 the regions of C-myc mRNA exhibited great inhibitory effects (59.5 % and 62.7 %) on growth of HL-60 cells for a definite time. And no toxicity of the two antisense oligonucleotides was found on normal lymphatic cells of human. 　CONCLUSION: The sequence of antisense oligonucleotides complementary to 5′-44-61 of C-myc mRNA was designed newly by us may be turned into inhibitory medicine of HL-60 cells.

Treatment based on syndrome differentiation is an essential feature of traditional Chinese medical diagnosis. The interventions based on changes of syndrome types in randomized controlled trials are complicated, leading to the difficulty of blind method enforcement. This article described a double-blind method. It could be used in randomized controlled trials under the condition of different syndrome types and different medications. It numbered drugs in two stages, and in two phases to achieve double-blind. This method not only guaranteed investigators and subjects to be in blinded conditions, but also achieved using different medications for patients of different syndromes. It also caused no drug waste. It was scientific and feasible.
