3 months. Female gender, adenocarcinoma history, non-smoking history, good PS and the presence of multiple lung metastases are associated with improved responsiveness to Gefitinib. Reflecting the results of previous clinical trials, the reports indicate that Gefitinib is generally well tolerated by Asian patients. The incidence of interstitial lung disease appears to be higher in Japanese than non-Japanese patients, although the reason for this is not clear. Recent findings regarding Erlotinib and other targeted therapy among Asian patients are discussed.

The performance status(PS)≥2 patients with non-small cell lung cancer(NSCLC) are short of effective management.The phase Ⅱ/Ⅲ clinical trails of target therapy of anti EFGR of VEGFR have already got promise results.This article expatiates the actuality and development of the chemotherapy and novel target therapy for the PS≥2 patients with NSCLC.

Lung cancer is the most common cancer and the leading cause of cancer-related deaths in the world. More than 50 % of advanced NSCLC are diagnosed in patients older than age 65 years. Aging is inextricably associated with decreases in marrow reserve, drug clearance, and lean body mass. Elderly cancer patients often present with medical and physiologic challenges that make the selection of their optimal treatment daunting. This article reviews the progress in diagnosis and treatment of lung cancer in the elderly in recent years.

The results of chemotherapy in the treatment of advanced non-small-cell lung cancer (NSCLC)had reached a plateau.Targeted therapy is the key to improving efficacy.In the last 5 years the epidermal growth factor receptor(EGFR)has emerged as one of the most important targets for drug development in oncology.Small molecules that inhibit the tyrosine kinase(TK)domain of EGFR have become new critical weapons in the treatment of NSCLC.Monoclonal antibodies targeting the external domain of EGFR have been shown to have clinical benefit when combined with chemotherapy.Recent data suggest that multitargeted inhibitors might have greater activity owing to their ability to simultaneously block key signaling pathways.Preliminary results of such agents in clinical trials shows that they have a well-tolerated toxicity profile,and might have a promising value in the treatment of advanced non-small-cell lung cancer.

Recent progress in molecular biology has enabled us to better understand the molecular mechanism underlying pathogenesis of human malignancy including lung cancer, the advent of therapies based on mechanisms that target critical molecular pathways of tumors has evoked considerable interest. The therapeutic index is high, and optimally effective treatment can be achieved at a dose below the maximal tolerated dose,giving us a better understanding of the human lung cancer. This review focuses on the advance of targeted therapy for the first-line, second-line treatment or the maintenance treatment of non-small cell lung cancer.

OBJECTIVE: To study the protective effect of 3-acetyl- 4-acetoxy-2-benzoxazolone on liver injury induced by carbon tetrachloride (CCl4) in mice. METHODS: The serum activities of ALT and AST and the levels of MDA, SOD and GSH in liver tissue were measured in the model of acute liver injury induced by intraperitoneal injection 0.15% CCl4 and hepatic histological changes were observed by optical microscope. RESULTS: Compared with control group, the serum ALT, AST and the liver tissue MDA activities were significantly lowered, the levels of SOD and GSH in liver tissue were increased obviously. Histological results showed that 3-acetyl- 4-acetoxy-2-benzoxazolone could ameliorate histological damages induced by CCl4 in mice. CONCLUSION: 3-Acetyl-4-acetoxy-2-benzoxazolone exhibits protective effects on experimental hepatic injury.

Lung cancer, a malignant cancer with highest death rate, severely threats the people's health. 80% lung carcinomas are non-small cell lung cancer (NSCLC). Recent studies have found that estrogen system has close relationship with the biological behaviors of NSCLC. Meanwhile, the level of estrogen influences the progression of disease and the prognosis of lung cancer patients. As a result, estrogen pathway has become a hot target in NSCLC treatment. This paper reviews the recearch advances of estrogen system in NSCLC treatment.

This article discussed the necessity and research significance of TCM literature digitization from the aspects of features of TCM literature and connotation and advantages of literature digitization. It introduced the research background of TCM literature digitization by using the examples of domestic and foreign digital libraries and digitized periodicals, expounded the research status of TCM modern and ancient literature digitization, elaborated the research condition of TCM ancient literature digitization, and analyzed the existing problems and provided suggestions.

[Objective]To investigate the influence of Nitinol modified on its surfaces by the coating of titanium or titanium-niobium alloy on separat ion of Ni~(2+).[Method]The specimens from 1 to 7 days after the experiments were collected and the concentration of Ni~(2+) were cletermined by physiologic saline immersing test,low temperature ashing furnace,Mg(NO_3)_2 as matrix modifier and graphite furnace atomic absorption spectrometry(GFAAS).[Result]Specimens of Nitinol were devided into 3 groups:alloy coated with Ti(Ti group);alloy with Titanium-Niobium(TiNi group);only Nitanol without coating group.Obvious separation of Ni~(2+) was detected in the groups of Nitinol that were not modified and were put in baking oven(37℃),the separating procedure was mainly within 4 days,the separation rate(10~(-7)??g? cm~(-2)?s~(-1)) from the first to the forth days was 18.2,3.45,1.75 and 0.45 respectively,the Ni~(2+)was no more separated from the fifth day.Whereas,Ni~(2+) was not separated in the groups of Nitinol that were modified by the coating of metallic Ti and TiNb alloy.The recovery rate of the experiments was between 94.6%～108.6%.[Conclusion]The coating of Ti or TiNb on the surfaces of Nitinol stopped Nitinol from separating Ni~(2+).
