Objective:To construct and identify the chimeric mtb8.4/hIL12 eukaryotic expression plasmid.Methods:Firstly mtb8.4-linker was amplified by PCR and cloned into the single Nhe Ⅰ and Mlu Ⅰ cloning sites of pCI-neo, so pCI-neo-mtb8.4-linker(pML) plasmid was constructed.Secondly hIL-12 was amplified by PCR and cloned into the single Mlu Ⅰ and Sal Ⅰ cloning sites of pML.Finally correct pCI-neo-mtb8.4/hIL12 (pMI) plasmid was identified by PCR,RE digestion and DNA seguencing.Results:The accuracy of pMI plasmid construction was confirmed by a number of molecular biological techniques.Conclusion:The construction of mtb8.4/hIL12 chimera by linkage of M.tuberculosis mtb8.4 gene to human IL12 gene provides the possibility for investigating a new tuberculosis vaccine.

Objective:To investigate the effects of ?-lipoic acid on cell proliferation and expression of intercellular adhesion molecule1(ICAM-1) induced by high glucose(HG) in rat mesangial cells(MCs).Methods: Rat mesangial cells were co-cultured with normal glucose(5.6 mmol/L,NG group),high glucose(25 mmol/L,HG group),and HG+?-lipoic acid(50,100,200,300 ?mol/L)for 12,24 and 48 h,respectively.Cell proliferation was assessed by MTT;the levels of ICAM-1 in the supernatants were determined by enzyme-linked immunosorbent assay(ELISA);and ICAM-1 mRNA expression was measured by semi-quantitative RT-PCR.Results: ?-lipoic acid at 50-300 ?mol/L inhibited the proliferation of MCs.Semi-quantitative RT-PCR showed that ?-lipoic acid(100 and 200 ?mol/L)significantly inhibited the high glucose-induced increase of ICAM-1 mRNA((P

The National Comprehensive Cancer Network(NCCN)is an alliance of 21 world leading cancer centers in the U.S.A,working together to develop treatment guidelines for most cancers.The primary goal of all NCCN initiatives is to improve the quality,effectiveness,and efficiency of oncology practice so that patients can live better.The NCCN guidelines have become the most widely used in oncology practice.These guidelines are updated continually and are based upon evaluation of scientific data.The NCCN Esophageal Cancer Guidelines have no Chinese version at present and were not yet used in our clinical practice.We are in an attempt to interpret the NCCN Esophageal Cancer Guidelines in conjunction with our clinical practice in the management of esophageal cancer.

You ought to differentiate the cause, location, nature and trend of disease, for chronic nephritis. The causes inducing or worsening the disease can be exopathy, as well as internal injury, pathological substance and drug pathogenic factors; while the deficiency of Qi blood Yin Yang of organs is often the internal basis of the disease. The location mainly concerns lung, spleen, liver and kidney, esp. kidney. The nature is deficient root and excessive superficiality; its general trend mostly appears Qi deficiency-both deficiency of Qi and Yin(blood)- both deficiency of Yin and Yang, a discipline of gradual development, and wind, wetness, heat, stasis, sputum and toxin worsen the development of the disease.

Objective] To explore the effect of the teaching method“3-round 4-step”on course“Selected Readings of Neijing(the Internal Cannon of Medicine)”. [Method] The teaching method“3-round 4-step”is helpful to improve students’grasping TCM theories, whose exam at ordinary times and final exam were respectively 83.23 and 79.62; in the other group of“paraphrase following text”teaching method, the results were 78.27 and 75.91 respectively; the comparison of both had statistical meaning. “3-round 4-step”teaching method contributes to promote students’ability of using TCM theories analysis and problem-settlement, widen their getting TCM relative theory and knowledge; their case analysis and thesis writing results were respectively 77.92 and 74.31; the results of the other group of teaching method “paraphrase following text”were respectively 73.27 and 69.45; the comparison of both groups had statistical significance. [Conclusion] Applying the teaching method of“3-round 4-step”can better finish the teaching task of“Selected Readings of Internal Classics”as improvement subject in later period.

Now, parts of the medical personnel have some problems such as low professional moral accomplish-ment, lack of sense of responsibility, professional skills and post does not match, faith is not strong, and so on. The external environment and internal weakening sense for cultivation are the main reasons.Therefore, optimizing the external environment, improving the education system, strengthening medical personnel’ s values, could pro-mote the formation of medical staff’ s professional personality, and eventually led to a powerful implement of social-ist core values in medical practice.

Objective To explore the effectiveness of comfort nursing on the parents of children with laryngopharyngeal surgery.Methods Forty-seven parents were admitted for the study,they were divided into the control group(23 cases) and the experimental group(24 cases).The control group accepted routine nursing,while the experimental group accepted comfort nursing based upon routine nursing.The SAS,SDS scores and satisfaction degree were compared between the two groups.Results After the treatment,the SAS and SDS scores of all the parents got better compared with those before treatment.The differences were obvious.While the experimental group had a better improvement than the control group.Also the satisfaction degree of the experimental group was better than that of the control group.Conclusions Comfort nursing can relieve the discomfort and anxiety of the children patients and their parents,improve the adverse emotional state of them,promote recovery of children and improve the nursing quality.

Objective To investigate the application value of the plasma homocysteine (Hcy) ,folic acid (FA) and vitamin B12 (VB12 ) levels in the patients with coronary heart disease (CHD) and CHD complicating impaired glucose tolerance (IGT) .Methods 80 triers screened by the inclusion criteria were divided into the simple CHD group (36 cases) and the CHD complicating IGT group(44 cases);70 healthy cases were taken as the controls .Hcy ,FA and VB12 levels were measured and the detection results were performed the statistical analysis .Results The Hcy level in both experimental groups were higher than that in the control group , the difference was statistically significant (P<0 .05) ,the positive rates were 94 .4% in the simple CHD group and 88 .6% in the CHD complicating IGT group respectively ;The plasma FA level in both experimental groups were lower than that in the control group ,meanwhile ,plasma Hcy level and FA level showed a negative correlation (P<0 .05);The VB12 level had no statistical differ-ence among 3 groups (P>0 .05) ,and the correlation analysis between the Hcy level in the two experimental groups with VB 12 had no statistical significance (P>0 .05) .Conclusion Plasma Hcy level in CHD and CHD complicating IGT is very high and negatively correlated with the FA level ,dynamically detecting the Hcy level has an important significance for early warning and treatment of CHD and CHD complicating IGT .

Objective] To explore the application of “viscera state”theory in “Internal Classics”in TCM diagnosing and treating hematuria. [Method] Clear up the“viscera state”theories in“Internal Classics”related to TCM diagnosing and treating hematuria, combining with concerned thesis of doctors in the past dynasties, to analyse its application value in clinic. [Result] “Heart joining with smal intestine through the meridian and col ateras”,“smal intestine being organ of receiving food and digestion”, “kidney connects lung upward”, “spleen storing Ying”, “spleen Qi disperseing essence and returning to lung upward”,“liver storing blood”,“kidney being organ of water”and“kidney opening into 2 lower orifices”, such“viscera state”theories are helpful to correct position of hematuria in TCM, define the mechanism and correct the treatment; doctors in the past dynasties had development on this, which is proved by the modern clinic. [Conclusion]“Viscera state”theories in“Internal Classics”have important guiding meaning in TCM diagnosing and treating hematuria.
