Objective:To explore the drug application in the postoperative chemotherapy for the patients with non-small cell lung cancer. Methods:The chemotherapy regimens, drug utilization and adverse drug reactions in the non-small cell lung cancer patients received postoperative chemotherapy in 2012 were statistically analyzed in a retrospective study. Results:Totally 8 kinds of chemother-apy regimens were used in 156 cases. The NC( vinorelbine + carboplatin) regimen was used most frequently and the PC( pemetrexed+ carboplatin) regimen was with the highest expense. Proton pump inhibitors, recombinant human erythropoietin and lentinan were the top three in the adjuvant drugs used in the treatment. Conclusion:It is necessary to further standardize the postoperative chemo-therapy for non-small cell lung cancer patients. Thoracic surgeons along with pharmacists should strengthen the drug use monitoring during the whole treatment process to promote the rational drug use.

Purpose: To study the influence of estrogen on the proliferation of human carcinoma cells. Methods: Treated with different concentrations of estrogen, the influence of estrogen on MCF7 was detected by MTT test. Several proteins related with cell cycle, tumor suppressor, proliferation and apoptosis were detected by the method of Western blot. Results: MTT test showed that estrogen could promote the proliferation of MCF7. Cyclin Dl was increased at the same time. But the protein level of PTEN, a tumor suppressor gene, was not changed by estrogen. Furthermore, as an anti -apoptotic protein, PKB protein level was also unchanged. Conclusions: Estrogen can promote the proliferation of human carcinoma cells by certain pathways including cyclin Dl, but not including PKB.

Objective To investigate the functional features of resveratrol on vasodilatation of abdominal aorta in rat and its underlying mechanism. Methods Isolated aortic ring was perfused and the tension of the vessel was measured. Results Resveratrol showed a dose-dependent relaxant effect on rat aorta at 4?10 -9~4?10 -5mol/L. At the concentration of 4?10 -5mol/L, the effect was attenuated by (74.9?1.9)% in the endothelium removal group, and it was significantly different from the control group (P0.05). At the concentration of 7?10 -5mol/L, resveratrol showed an relaxant effect on de-endothelium vessels. Conclusion Resveratrol relaxes the aorta in both endothelium dependent and independent manner. In the endothelium-dependent manner, the mechanism of vasodilatation may be associated with NO system and KATP channel, while in the endothelium-independent manner effect of resveratrol might be a direct one.

AIM: To analyze curative effect of four regulating-intestines prescriptions (Wumei Wan, Baitouweng Tang, Shenling Baizhu San and Tongxie Yao-fang) on the treatment of ulcerative colitis (UC) through summing up the previous animal experimental results.METHODS: We collected the conclusions in the papers related to four regulating-intestines prescriptions for the treatment of UC which were published recently, made comparisons from the aspectsof symptoms, physical sign, pathological change, cytokine and its protein expression, blood adhesion molecule, cell apoptosis and controlling gene and analyzed the pathogenesis of UC and action mechanism of four regulating-intestines prescriptions. Four regulating-intestines prescriptions included Wumei Wan,Baitouweng Tang, Shenling Baizhu San and Tongxie Yaofang. Wumei Wan is from Treatise on Exogenous Febrile Diseases and Synopsis of the Golden Chamber, which consists of dark plum, asarum herb, dried ginger, Chinese goldthread, Chinese angelica root, aconite root, pricklyash peel, cassia twig,ginseng (sun-dried ginseng) and bark of cork tree and has marked effect in treating colic caused by ascariasis and persistent dysentery. Baitouweng Tang, from Treatise on Exogenous Febrile Diseases, consists of medicinal herbs such as pulsatilla root, Chinese goldthread, bark of cork tree and ash bark, which has functions of clearing away the heat-evil, expelling superficial evils and relieving dysentery. In addition, it has marked effect in treating heat-type dysentery. Shenling Baizhu San, from Prescriptions of Peaceful benevolent Dispensary, consists of medicinal herbs such as pulp of lotus seed, coix seed, amomum fruit, balloon flower root, white hyacinth bean, poria, ginseng (sun-dried ginseng), glycyrrhiza, bighead atractylodes and rhizoma dioscoreae, which has the nature of replenishing qi to invigorate the spleen and eliminate wetness to arrest diarrhea and has marked effect on treating diarrhea due to the hypofunction of spleen. Tongxie Yao-fang which is from The Complete Works of Zhang Jingyue consists of four herbals of agehead atractylodes, root of herbaceous peony, dried tangerine peel and ledebouriella root and has the functions of soothing liver and invigorating spleen and stopping diarrhea, and has marked effect on treating liver sthenia and deficient spleen, borborygmus and abdominal pain and diarrhea.RFSULTS: ① Because UC is a chronic protracted dysentery with deficiency of vital energy and existing of evil energy, the vital energy will be harmed if its treatment is specialized in removing and dissolving the stagnation, evil energy will continue to exist and stagnation will continue to accumulate if its treatment is specialized in strengthening vital energy and inducing astringency. Only supporting healthy energy and expelling evil energy is the correct therapy method. This is in accordance with the main treatment of Wumei Wan ②Eliminating dampness and pathogenic heat from the blood to treat diarrhea is the main treatment method of Baitouweng Tang, and this is incompletely suitable for the treatment of UC.③Shenling Baizhu San had the effect on soothing liver and invigorating spleen and stopping diarrhea, and this is also incompletely suitable for the treatment of UC. ④ The prescription of Tongxie Yaofang is used for treating diarrhea caused by deficient spleen and liver sthenia, and spleen controlled by liver, and abnormal ascent and descent. It accords with main pathogenesis of UC, deficient spleen, excessive dampness of deficient spleen and it is weaker in invigorating the spleen in catabasis of UC than Shenling Baizhu San. Therefore, Wumei Wan has the best curative effect,Baitouweng Tang the second, Shengling Baizhu San the third and Tongxie Yaofang a little poor.CONCLUSION: UC belongs to recurrent dysentery, and its pathogenesis is in accordance with the main treatment of Wumei Wan, but not the other three prescriptions, so Wumei Wan is the most efficient prescription in treating ulcerative colitis. Diagnosis and treatment based on an overall analysis of signs and symptoms of TCM is the premise of obtaining the best curative effect. Modeling of animal tests must be consistent with the type of syndrome of the traditional Chinese medicine. Ating ulcerative colitis (UC) from aspects such as symptom, physical sign, pathological changes, adherence factor, cytokine and its protein expression, apoptosis and its controlling gene by means of modeling, which proves their functions and effects are different and their curative effect are also different due to their different ingredient though they all have the functions of treating. Results of this test show Wumei Wan has the best curative effect, Baitouweng Tang the second, Shenling Baizhu San the third and Tongxie Yaofang a little poor[1-11] Mechanism of four regulating-intestines prescription in the treatment of ulcerative colitis is discussed from the viewpoints of traditional Chinese medicine as follows.

Objective To observe the expression of Glu、mGluR 5 and EAAT 1 in bone tissues of ovariectomized osteoporotic rats and the effects of Total Flavonoids of Rhizoma Drynariae (TFRD) on it. Methods 45 SPF 3-month-old Sprague-Dawley (SD) female rats were randomly divided into sham operation (Sham, n=15) group and ovariectomized (OVX, n=30) group. The osteoporotic(OP) model was established by bilateral ovariectomy, 14 weeks later, we measured bone mineral density(BMD) by dual-energy X-ray and determined that OP model was successfully replicated, OVX group rats were then divided into OVX group (n=15) and OVX+TFRD group (n=15). The OVX+TFRD group was given TFRD for 12 weeks. Glutamate (Glu), metabotropic glutamate receptor 5 (mGluR 5), and Glutamate/Aspartate Transporter (GLAST/EAAT 1)’s expression of femur was examined in order to clarify the characteristics of bone glutamate signaling pathway and the effects of TFRD on it. Results Glu and ionotropic receptors mGluR 5 mainly distributed in bone marrow cells and osteoblasts closed to the bone marrow cavity walls. There were no significant differences in Glu expression among Sham group, OVX group and OVX+TFRD group. The mGluR 5 expression of OVX+TFRD group was significantly higher than that of Sham group and OVX group(P=0.009), while no significant difference was found between the latter two groups. In addition to large distribution in bone marrow cells, small amount of transporter EAAT 1 was noted to express in bone cells of the bone lacunae. There were no significant differences in EAAT 1 expression among the three groups. Conclusion In bone glutamate signaling pathway, this study demonstrated that TFRD could significantly improve the ionotropic receptor mGluR 5’s expression, but had no inlfuence for Glu and EAAT 1.

Objective To compare the sub-cellular proteome of isoniazid ( INH)-resistant Mycobacterium tuberculosis (MTB) with that of sensitive strains for identifying of unique proteins of these strains and discussing their preliminary application in clinical diagnosis. MethodsProteins of cell wall and membrane of 5 INH-resistant strains and 5 INH-sensitive strains were extracted by density gradient centrifugation.The extracts were subsequently analyzed using weak cation exchange (WCX) liquid chromatography ( LC )followed reverse phase (RP) liquid chromatography to compare the sub-cellular protein patterns. A total of 1280 fractions were collected and identified by matrix assisted laser desorption ionization-time of flight-tandem mass spectrometry (MALDI-TOF MS/MS). The Database for Annotation, Visualization and Integrated Discovery (DAVID) was used for cell component and biological process analysis. Normalized Spectral Abundance Factors (NASF) was used for semi-quantity of protein expression. 5 proteins significantly up-regulated in INH-resistant strains and 2 proteins significantly up-regulated in INH-sensitive strains were selected for ELISA analysis with autologous sera respectively. Results A total of 347 proteins were identified. Cell component analysis showed that 58% proteins were cells well or membrane proteins. Biological process analysis showed that 31% proteins involved in carboxylic/monocarboxylic acid biosynthetic and metabolic process, 26% and 15% proteins involved in organic acid or fatty acid biosynthetic and metabolic process,while 28% proteins involved in lipid biosynthetic , metabolic, transport and localization process. O-succinylbenzoate synthase, monooxygenase, hypothetical protein Rv2255c, nicotinate-nucleotide--dimethylbenzimidazole phosphoribosyltransferase and membrane phosphatidate cytidylyltransferase cdsA were up-regulated in INH-resistant strains and fractions contained these proteins could elicit specific antibody response with autologous sera. The A450 was higher than that with INH-sensitive sera. The differences between the INH-resistant sera and the INH-sensitive sera were significant ( t = 0.028, 0.044, 0.066, 0.064, 0.083, all P<0.01 ). Chain A of Rv2002 Gene Product and Chain A of Crystal Structure Of Rv2632c were up-regulated in INH-sensitive strains and fractions contained these proteins could elicit specific antibody response with autologous sera. The A450 was higher than that with INH-resistant sera. The differences between the INH-sensitive sera and the INH-resistant sera were significant (t=0.053, 0.073, both P<0.05). ConclusionThe combination of density gradient centrifugation and 2D-LC MS/MS technology is useful in enrichment and identification of differential expressed proteins between INH-resistant and INH-sensitive strains at sub-cellular level. It is useful in finding antigens associated with INH-resistant MTB infection, which may prove useful for further study in the mechanism of INH resistant, as well as interaction between MTB and host.
