This article summarized the mechanism of traditional Chinese medicine treatment for lung cancer in recent years. Related literatures were from the immune regulation, inhibiting growth and metastasis of lung cancer cells and promoting apoptosis and reversing drug resistance. Review showed that traditional Chinese integrated with western medicine for lung cancer has gradually become the consensus of clinical practioners.

OBJECTIVE :To study the preparation technique and clinical therapeutic effect of Tangan capsules METHODS : Tangan capsule was made of chrominum pyridinate ,crystalline cellulose ,starch and vehicle The content of chrominum pyridi natein product was detected with HPLC RESULTS :This preparation was rationalin design ,feasible in preparation technique , stable in quality,reliable in quality control and satisfactory in the rapeutic efficacy CONCLUSION :Tangan capsuleis of im portance as an accessory agent in treating type 2 diabetes.

Objective: To explore the defense mechanism of patients with Obsessive-Compulsive Disorder(OCD)and to measure the changes in defense mechanisms after the treatment. Methods: Before and after 10- week psychotherapy , 26 patients with OCD were assessed with the Defense Style Questionnaire(DSQ)and Yale-Brown Obsessive-Compulsive Scale(Y-BOCS); DSQ were also used to test 26 normal subjects. Results: (1)The scores of immature mechanism factor (4.5?0.8)were significantly higher in OCD patients than in normal(3.0?0.5),the scores of mature mechanism factor(5.0?0.8)were significantly lower in OCD patients than in normal (5.7?0.7); (2)After 10- week psychotherapy the scores of immature mechanism factor(4.0?0.9)were significantly lower than before (4.5?1.0),the scores of mature mechanism factor(5.7?0.7)were significantly higher than before (5.0?0.9).Conclusion: OCD patients often use immature mechanism, but after psychotherapy, they can use more mature mechanism.

Objective To explore the clinical value of video-assisted thoracoscopic mediastinal tumor resection.Methods The clinical data of 32 patients(observation group) who performed video-assisted thoracoscopic mediastinal tumor resection were retrospectively analyzed,compared them with 53 patients with mediastinal tumor who underwent traditional thoracotomy (control group).The clinical outcomes including operation time,intraoperative blood loss,chest drainage duration,postoperative hospital stay,postoperative complication and postoperative analgesia drug application were compared between two groups.Results No perioperative death was observed in two groups.There were no statistical difference in operation time between two groups [(121.9 ± 41.2) min vs.(141.7 ± 35.2) min] (P ＞ 0.05).The observation group was significantly better in the intraoperative blood loss [(116.0 ±53.2) ml],chest drainage duration [(5.2 ± 1.2) d],postoperative hospital stay [(8.5 ± 1.3) d],postoperative analgesia drug application [(0.8 ± 0.7) times],postoperative comolication (3 cases),than those of the control group [(147.2 ± 45.2) ml,(6.8 ± 2.2) d,(11.2 ± 2.4) d,(2.1 ± 0.9) times,15 cases].There were statistical differences between two groups (P ＜0.05).Conclusion Complete video-assisted thoracoscopic mediastinal tumor resection is a valuable way in the treatment of mediastinal tumor,rapidly recovery and less postoperative complication.

Streptomyces phage ?C31 integrase is a site-specific recombinase and introduce foreign gene to unidirectional recombination.Because of its integration mediated by ?C31 integrase without any cofactors and especially directed integration,it possesses high efficiency and stable expression of foreign gene.These advantages make it an attractive tool for genetic engineering.It has been widely used to transgene integration in mammalians and provides an opportunity to overcome the bottlenecks in the generation of transgenetic animals,such as random integration,low integral rate,low level of expression and so on.The ?C31 integrase will have a wide application in the near future.

In observing the therapeutic efficacy of insulin sensitizer in treatment of early T2DM,120 T2DM patients were randomly divided into 3 groups: group A received 4 mg rosiglitazone daily;group B received 1.5 g metformin daily;group C received 4 mg rosiglitazone and 1.0 g met-formin every day.Before and after the treatment,fasting glucose,HbA1c,weight,adiponectin,BMI and HOMA-IR were measured or calculated.We found that fasting glucose,HbA1c and HOMA-IR of 3 groups were obviously decreased in comparison with their baseline and adiponectin was significantly increased.In conclusion,insulin sensitizer can obviously decrease the levels of glucose,HbA1c and HOMA-IR,and increase the level of serum adiponectin in T2DM.Insulin sensitizer in combination of metformin is suitable for treatment of T2DM.

Objective The purpose of this study was to investigate the clinical significance of pre-operative combined detection of metastasis-relative genes in non-small cell lung cancer. Methods Peripheral blood lymphocyte specimens from 46 patients before operation and fresh tissue specimens after operation were examined by RT-PCR analysis of CD44v6 and nm23H1 mRNA. The results were compared to the pathological diagnosis of lymph node metastases. ROC curve was used to determine the cut-off value of pre-operative metastases prediction. Results The relative amount of CD44v6 mRNA was higher (P

GC retention index of volatilc component of Cyperus rotundus was studied by capillary Gas Chromatography, and the standard Gas Chromatographic diagram and GC retention in dex spectrum, which provide a new identification method for traditional Chinese medicine was established. This method may be used to difierentiate the genuine C. rotundus from other false or confusion products. The average CV (% ) of RI from 37 sets of C. rotundus from three differcnt producing areas were 0~0.24 The method posscsses well accuracy, comparability and good reproducibility
