Objective To observe clinical effect of Chinese medicine combined chemotherapy in the treatment of elderly patients with advanced non-small cell lung cancer. Methods 61 cases of elderly patients with advanced non-small cell lung cancer patients were randomly recruited into two groups. 30 cases in treatment group, which was treated with Chinese medicine combined single-drug chemotherapy, 31 cases in control group, which was treated with Chinese medicine combined combination-chemotherapy. After 42 days of 2 cycle, the clinical effect of both groups was observed. Results The treatment group was superior to the control group on improvement of quality of life, symptomatic improvement, the toxicity of chemotherapy and treatment costs. The difference between the two groups were significant (P< 0.05) . Conclusion Chinese medicine combined single-drug chemotherapy in the treatment of elderly patients with advanced non-small cell lung cancer is superior to combined combination-chemotherapy.

This paper described the progress of treating elderly patients with advanced non-small cell lung cancer both domestically and abroad. The advantages of Chinese medicine and Chinese medicine combined with chemotherapy were emphasized.

Objective To analyze the development, treatment, death cause and survival situation of malignant tumor in aging patients Method Retrospectively analysis was made on 106 aging patients died of malignant tumors, who received the treatment in our hospital. Result Of all 106 patients, 102 patients were in advanced stage(Ⅲ+Ⅳstage), occupying 96.23%,most of who also had some other basic senile diseases; 96.23% patients had been treated with TCM, which exceeded the ones who were treated with chemotherapy, radiotherapy and operation. Some aging patients with tumor had better survival time than other age patients; the top three causes of death for tumor were respiratory failure, infection and congestive heart failure. Conclusion Most of aging patients with malignant tumor were in advanced stage, TCM treatment is easily to be accepted by patients, due to its fewer side effects. In the meantime, we should treat the basic senile diseases positively and prevent their complications.

Objective To analyze the clinical features and interval of multiple primary carcinoma (MPC). Methods 52 patients with MPCs between October 2002 and May 2007 were reviewed. Results 7 patients had synchronous carcinoma (13.46%), and 45 had metachronous carcinoma (86.54%). The interval between the first primary cancer and MPC was from 0 to 31 years, averaged 7.1 years. Male was 7.3 years, and female was 9.3 years (P

Objective:To establish a patient-derived xenotransplantation (PDX) animal model of gastric cancer, and observe the anti-cancer effect of chemotherapeutic drugs on this model.Methods:Human gastric cancer tissues were inoculated into the subcutaneous tissues of both axillaries of NOG mice and were subcultured for 3 generations. The tumor tissues of the third-generation NOG mice were selected and inoculated into the subcutaneous tissues of left axillary of 21 severe combined immunodeficiency-non-obese diabetes mellitus (SCID-NOD) mice to establish PDX mouse model of gastric cancer. The inoculated mice were divided into control group (mice received only 0.9% sodium chloride injection), oxaliplatin group, cisplatin group, paclitaxel group, fluorouracil group, tegafur, gimeracil and oteracil porassium capsules group and capecitabine group, with 3 mice in each group, and the corresponding drugs were given. The mice survival status, tumor volume and tumor weight at different times were recorded. Mice were sacrificed on the 61st day of administration, and the tumor inhibition effects of 6 kinds of chemotherapy drugs on the PDX model of gastric cancer were evaluated.Results:After being subcultured for 3 generations, the stability of tumor transmission in PDX animal model of gastric cancer was improved, and the homogeneity of tumor growth was good at the initial stage. At the early stage of administration, the model was more sensitive to oxaliplatin, fluorouracil and capecitabine, and the tumor growth inhibition (TGI) values on the 31st day were 63.37%, 52.11% and 78.48%, at the end of administration, the model had the best sensitivity to capecitabine with a TGI value of 59.22% and a tumor inhibition rate of 58.65% on the 61st day. The TGI curve after administration showed that paclitaxel had no obvious anti-tumor effect, cisplatin had the worst anti-tumor effect, and the model had poor tolerance to tegafur, gimeracil and oteracil porassium capsules.Conclusion:The PDX animal model of gastric cancer is successfully established, and capecitabine has the best tumor suppressive effect on this model.

Objective:To develop a new preparation process of PLGA microparticles for protein drugs by SPG membrane emulsifi-cation combined with W/O/W double emulsion-solvent technique. Methods:Lysozyme was used as the model drug to prepare the mi-croparticles. The influence of formula factors on the properties of the microparticles was studied, and the physicochemical properties, in vivo compatibility and degradation of the microparticles were investigated as well. Results:The drug loading of lysozyme-loaded mi-croparticles was 35%, the entrapment efficiency was 72. 43% and the average size was 63. 89 μm with PDI of 0. 675. DSC and FTIR showed that lysozyme was entrapped in the microparticles. The microspheres had promising biocompatibility and sustained degradation in vivo. Conclusion:The paper describes a new satisfactory preparation process of PLGA microparticles for protein drugs with good in vitro and in vivo properties.

Objective To fractionate phosphoproteome of mouse liver by two-dimensional (2D) liquid phase chromatography fractionation. Methods Phosphoproteins were extracted from lysates of normal mice livers by phosphate metal affinity chromatography (PMAC) resin. The phosphoproteins were exchanged by start buffer and separated by chromatofocusing in the first dimension. Then the fractions between pH 8.5 and pH 4.0 were separated by non-porous silica (NPS) reverse-phase high performance liquid chromatography (RP-HPLC). Finally, the UV maps were converted into gel-like maps by ProteoVue software. Results Phosphoproteins of mouse liver were successfully extracted and fractionated by two dimensional liquid phase chromatographic fractionation after concentration and desalt. Then pI/UV map of mouse liver phosphoproteome was successfully set-up. There are 16 fractions between pH 8.5 and pH 4.0 after chromatofocusing in the first dimension and the UV maps of each fraction were converted into pI/UV gel-like maps. Conclusions Combination of technique of phosphoproteins enrichment and 2-D liquid phase chromatographic fractionation is an effective approach to research phosphoproteome and the key base for further identification and investigation of phosphoproteins.

Objective To evaluate the pathogenesis and disease progression by detecting the expression of Serum High mobility group protein 1 (HMGB1) and TLR2 in monocytes of patients with systemic lupus erythematosus (SLE).Methods Forty patients with SLE were selected randomly,20 patients were in active disease group and others were in stable disease group.The expression of HMGB1 in the serum of these cases were detected by enzyme linked immunosorbent assay (ELISA) and TLR2 on CD14+ monocytes in the peripheral blood were detected by FCM.The correlation between these indexes and clinical,laboratory indexes about SLE were analyzed using one-way ANOVA,and Kruskal-Wallis test.Results The expression levels of HMGB-1 in serum was [(48.9±11.3) μg/L] in the active group,while that was [(14.8±1.9) μg/L] in the stable group was,and [(13.5±3.6) μg/L] in the control group.HMGB1 in the active SLE group was significantly higher (P＜0.05) when compared with that of the stable and control group.The expression of TLR2 in the peripheral blood mononuclear cells was [(96.7±1.3)％] in the active group,[(83.5±9.1)％] in the stable group,and [(83.3±9.9)％] in the control group TLR2 in the active SLE group was up-regulated when compared with the stable and control groups (P＞0.05).There were positive correlation between the serum levels of HMGB1and TLR2 in the peripheral blood mononuclear cells (r=0.551,P＜0.05).Conclusion The expression levels of HMGB-1 in serum and the expression of TLR2 in peripheral blood mononuclear cells may participate in the pathological processes of SLE.
