These data provide useful clues for elucidating the mechanisms of migraine with hyperactivity of liver-yang.

Objective: To study the mechanism of Qilantangzhining Capsule in treating diabetes mellitus complicated with hyperlipemia. Method: Rats were fed with high sugar and fat food for 2 months, and then 2% streptozocin (STZ, 30mg/kg) was injected intraperitoneally to induce hyperglycemic and hyperlipemic model. Thereafter, the model rats were administrated the drug. Flow cytometry (FCM) were used to detect effects of the capsule on hepatocyte apoptosis and the expression of related regulating genes, Bax and Bcl-2. Result: The rate of cell apoptosis remarkably increased among the model rats, the expression of Bax was significantly enhanced and that of Bcl-2 was decreased. Qilantangzhining Capsule could remarkably decrease the rate of cell apoptosis, decrease the expression of Bax, and increase that of Bcl-2. Conclusion: Qilantangzhining Capsule can prevent hepatocyte apoptosis by adjust the expression of Bax and Bcl-2, and accordingly provide evidences for its role in adjusting the metabolic disorders of sugar and fat.

Objective To analyse the long-term result and prognosis of 18 FDG PET/CT positioning three - dimensional conformal radiotherapy ( 3 DCRT ) for stage Ⅲ non - small cell lung cancer. Methods Sixty-four cases with stage Ⅲ non-small cell lung cancer (clinical stage Ⅲa- Ⅲb ) were randomly divided into two groups: PET/CT positioning three-dimensional conformal radiotherapy group (PET/CT group) and the conventional CT positioning three-dimensional conformal radiotherapy group (conventional CT group). In the PET/CT group, the target volume and critical organs were sketched according to PET/CT after fusion of the PET and the CT images; the treatment plan was worked out, then conventional fractionated 3DCRT ( total dosage around 40 Gy) followed by field-shrinked radiotherapy to a total dose of 65 Gy or sowas performed ;in the conventional CT group, the target volume and critical organs were sketched according to CT and 3DCRT were performed to the same total dose; All cases were treated with the TP scheme (paclitaxel 175 mg/m2,d1 ,cisplatin 40 mg,d2-4) adjuvant chemotherapy for 6 cycles after the radiotherapy. Results The followup rate was 100%. The number of patients who completed the 1-,2-and 5-year follow-up were 40,20 and 11 respectively ;The number of patients of the PET/CT group and conventional CT group were 23 and 17,11 and 9,7 and 4 respectively. Target volumes of 13 cases in the PET/CT group were changed. The complete remission and partial remission rates of the two groups were 13% 、66% and 19% 、53% (x2 = 0. 33, P =0. 564), respectively. The 1-,2-and 3-year local control rates of the PET/CT group and conventional CT group were84 % 、66% 、53 % an d72% 、59% 、44% ( x2 = 2.36, P = 0. 124 ) respectively. The1 -, 2-and 3-year survival rates were 72% 、34% 、22% and 53% 、28% 、13% (x2 =2. 46,P =0. 117) respectively. The level-1 and level-2 lungs' and trachea's late radiation injury of the PET/CT group and the conventional CT group were 28% and 53% ( x2 = 4. 14, P = 0. 042 ), respectively. The hilar and mediastinal lymph node recurrence rates of the PET/CT group were lower than those of the conventional CT group, were 3% ,25%(P = 0. 026) and 6%, 28% ( P = 0. 042 ), respectively. The main reason for treatment failure was distant metastasis both in the PET/CT group and conventional CT group,56% and 47% (x2 = 0. 56,P = 0. 453 ),respectively. Conclusions PET/CT, as a method of sketching the target of stage Ⅲ non-small cell lung cancer, can improve the radiation treatment plan, reduce the recurrence rate of hilar and mediastinal lymph nodes, meanwhile it can not improve the long-term survival rate; Distant metastasis was the main reason of failure.

Objective To investigate the effects of quetiapine on serum levels of brain-derived neurotrophic factors ( BDNF) and the correlation between BDNF and psychiatric symptoms and cognitive function in patients with first-episode schizophrenia. Methods Eighty patients with first-episode schizophrenia ( treatment group) were treated with quetiapine orally for 4 weeks,at initial dose of 100 mg·d-1 and average dose of (580±120) mg·d-1 . The psychiatric symptoms were evaluated by using the positive and negative syndrome scale ( PANSS) . The cognitive function was assessed by using Wisconsin cards sort test ( WCST) . The serum BDNF level was detected with enzyme-linked immunosorbent assay ( ELISA) . Results The serum level of BDNF was markedly lower in schizophrenic patients before[(13. 72±8. 79) ng·mL-1,P<0. 01] and after treatment[(18. 02±9.06) ng·mL-1,P<0.05]in comparison with normal controls(23. 67±10. 13) ng·mL-1]. After treatment,the PANSS total scores and subscale scores decreased,WCST number of categories and the number of correct answers increased,and the number of wrong answers reduced. There was a positive correlation between the serum BDNF and negative symptoms ( SANS) ( r= 0. 54, P=0. 032),and the number of correct answers. Conclusion The quetiapine significantly increases serum level of BDNF in schizophrenia patients,which correlates positively with improvements in symptoms and cognitive function.
