Objective To discuss correlation of hemodynamic changes and portal vein diameter with multi-slice spiral CT peffusion imaging in liver cirrhosis. Method 31 cases liver cirrhosis were enrolled in this study. The first porta hepatis were selected for target lay of CT perfusion scan. Liver perfusion parameters were obtained by color perfusion map method. Right to left diameter and occipitofrontal diame-ter of portal vein were measured. 30 cases of normal persons were used as control group. Result Hepatic arterial perfusion (HAP) in liver 0.05). Hepatic perfusion index (HPI) were (19.13±3.33)% and (20.61±8.56)%, which had no statistically significant difference with the other two groups (P>0.05). Conclusion Multi-spiral CT perfnsion imaging is an effectively noninvasive method to evaluate the hemodynamic changes of liver cirrhosis. Occipitofrontal diameter of portal vein with liver cirrhosis can reflect the state of liver hemodynamics.

OBJECTIVE:To discuss the correlation between multidrug resistance gene (MDR1) polymorphisms and plasma concentration of risperidone,9-hydroxyrisperidone and total active substance in Han patients with schizophrenia. METHODS:78 Han inpatients with schizophrenia in Mental Health Institute of Second Xiangya Hospital of Central South University from Dec. 2011 to Jan. 2013 were selected,LC-MS/MS was conducted to determine the plasma concentration of risperidone,9-hydroxyrisperi-done and total active substance,PCR-LDR was adopted to determine the genotyping of C1236T,G2677T and C3435T of patients, and one-way ANOVA was used to detect the correlation between C1236T,G2677T and C3435T polymorphisms and plasma concen-tration/dose calibration ratio (C/D) value of risperidone,9-hydroxyrisperidone and total active substance. RESULTS:The average plasma concentrations of risperidone,9-hydroxyrisperidone and total active substance for 78 patients were(13.58±8.31),(25.62± 15.52)and(39.24±25.76)ng/ml,respectively;the distribution frequencies of C1236T,G2677T and C3435T met the Hardy-Wein-berg equilibrium(P>0.05);the risperidone C/D value of patients with C12367T CT and TT genotype were higher than those with CC genotype,risperidone and total active substance C/D values of patients with G2677T TT genotype were higher than those with GG genotype,the differences were statistically significant (P<0.05);while there were no significant differences in analyte C/D values in other patients(P>0.05). CONCLUSIONS:The MDR1 C1236T and G2677T polymorphisms are associated with plasma concentration of risperidone and total active substance in Han patients with schizophrenia.

Objective: To observe the effects of manganese( Ⅲ ) meso-tetrakis (N, N'-diethylimidazolium-2-yl) porphyrin (MnTDM) in treatment of early Parkinson's disease(PD) mouse model induced by subcutaneous injection of 1-methyl-4-phenyl1, 2, 3, 6-tetrahydropyridine(MPTP) and to discuss its possible mechanism. Methods:Forty male C57BL/6 mice were evenly randomized into 4 groups: MPTP model group(subcutaneous injection of 25 mg/kg MPTP for 3 days), MnTDM+ MPTP group (15 mg/kg MnTDM was subcutaneously injected 1 h before MPTP injection), MnTDM control group, and normal saline group. Performance of animals in the pole and swimming test was observed 3 days after the last injection. Levels of dopamine (DA) and its metabolites(3,4-dihydroxyphenylacetic acid [DOPAC] and homovanillic acid [HVA]) in the striatum of animals were measured by high-performance liquid chromatography with an electrochemical detector(HPLC-ECD). Thiobarbituric acid (TBA) method was used to examine the levels of malondialdehyde(MDA). Results: Acute injection of MPTP could be used for establishment of PD model. The striatal levels of DA, DOPAC and HVA in MPTP group were significantly lower(P＜0.01)and the striatal level of MDA was significantly higher(P＜0.05) than those of the control group. MPTP had no obvious effect on the behavioral performance of the animals in a short term. MnTDM could partly inhibit the above effects of MPTP. Compared with MPTP group, MnTDM+ MPTP group had significantly higher DA, DOPAC, and HVA levels and significantly lower MDA level(all P＜0.05). There was no significant difference in the behavioral indices of animals between the 4 groups. Conclusion:MnTDM can inhibit lipid peroxidation and promote DA production; it has preventive and therapeutic effects on MPTP induced PD.

The theoretical basis of "corresponding points" originates from opposing needling, contralateral needling and distal needling in acupuncture. It is to select points in corresponding area that is distant from diseased re gion to balance yin and yang and to activate meridians. Acupuncture at corresponding points, through reflex regu- lation of nervous system. could activate protective inhibition of cerebral cortex and cutoff of local malignant stimu lation, leading to quick elimination of pain. In clinic, it is mostly used for pain-related diseases.
