OBJECTIVE To investigate the cause and and prevention experience of lung infection in the aged patients with gastrogavage at home.METHODS Retrospective analysis of lung infection was proceeded in 108 aged patients with gastrogavage at home during three years.RESULTS Among 108 patients with gastrogavage at home 83 patients developed infection in which 69 patients developed lung infection.For the aged patients with gastrogavage at home,inspiration and increasing incidence of retrograde infection from stomach to pharynx and lower respiratory tract were the main causes in developing lung infection.Moreover the lower immunity status,catching cold,changing the stomach tube not on time were the related risk factors in developing lung infection.CONCLUSIONS Enhancing the prevention of respiratory tract infection,increasing the nutrition,changing the stomach tube in time and prevention education would effectively decrease the incidence of infection and enhance the rehabilitation.

0.99).The IL-2 activity of control sample of our laboratory was determined according to recom-binant human IL-2 standard,the ability of IL-2 induced by rat and mouse spleen cells was compared, and the parameters of IL-2 induced by rat spleen cells were detected.The partially purified rat IL-2 was obtained through ammonium sulfate precipitation, gel filtration and chromatography.

Medical social work is a new arising occupation that provides professional medical service for patients in hospitals and communities based on the development of new medical mode,playing critical role in the therapeutic rehabilitation of certain diseases.Tumor diseases,especially malignant tumors,are serious hazards to human life and health,thus require special medical treatment and therapeutic rehabilitation due to their specific characteristics.Therefore,intervention of medical social work is of irreplaceable significance in the therapeutic rehabilitation of tumor diseases,promoting the realization of rehabilitation,soothing physical pains,providing psychological support,lengthening life expansion,enhancing the living quality of tumor sufferers,and assisting them better to regress to normal social life.

Based on my training experience in the United States,here introduced the situation of diabetes education and management in the United States,diabetes educator certification and the education program of outpatients and inpatients. This information can provide advice to improve the current status of diabetes education in China.

MicroRNAs (miRNAs) are a small noncoding family of 22 ut RNAs that play an important role in the negative regulation of gene expression at the post-transcriptional level by base pairing to the 3'untranslated region of target messenger RNAs.miRNAs are involved in a variety of basic processes,such as cell proliferation and apoptosis,metabolism and signaling pathways.A lot of studies have indeed described the aberrant expression of miRNAs in human tumors and have investigated their potential role as oncogenes or tumor suppressor genes,depending on the targets they regulate.Furthermore,more and more studies have demonstrated that an important role of miRNAs in anticancer drug resistance and miRNA expression profiling can correlate with the development of anticancer drug resistance.A systematic and intensive study on the mechanisms of miRNA in anticancer drug resistance will provide us a strong rationale for the development of miRNA-based therapeutic strategies aiming to overcome cancer cell resistance.This paper has reviewed the recent development of miRNAs involved in anticancer drug resistance.

Chimeric antigen receptor (CAR) T cell shows its significant therapeutic effect in part of leukemia and lymphomas, which indicates that transgenic adoptive cellular immunotherapy may be one of the breakthroughs in treatment of solid tumors and blood diseases. The functional inhibition of CAR endogenous cells in the tumor microenvironment , molecular biology function of molecules, difficulties of CAR T cells in clinical application and the solutions , how to improve the clinical efficacy and to reduce toxic side effects for future cancer immunotherapy in clinic are reviewed in this paper.

Objective　To evaluate the effect of vascular endothelial growth factor (VEGF) on tumor angiogenesis, and its usage in tumor therapy. Methods　The recent literatures about VEGF and angiogenesis were reviewed and analyzed. The advances of VEGF study were summarized. The effects of anti-angiogenesis in tumor biological therapy were introduced.Results　Angiogenesis had been identified as an important factor for promoting tumor growth. VEGF was a basic and pivotal factor in tumor angiogenesis. The anti-angiogenesis treatments aimed at VEGF, including the applications of VEGF inhibitor and gene therapy of adenovirus medium, had got great progress. Conclusion　 VEGF is a leading factor of tumor angiogenesis, the anti-angiogenesis therapy aimed at VEGF has probably provided a new chance to malignant tumor treatment.

Epilepsy is one of the nervous system diseases,which is correlated with multiple pathogenic factors and caused by repeated discharge of neurons.Currently,there are more than 50 million people worldwide suffering from epilepsy with an average annual increase of 100 000 cases.The prevalence rate of sleep disorders in epilepsy patients is high,by up to two times than that of healthy subjects.Common sleep disorders in epilepsy patients include insomnia,sleep apnea,restless legs syndrome and parasomnias.The characteristics of sleep abnormalities have differences with the epilepsy syndromes.The relationship between epilepsy and sleep is complex and interactive.The mechanism of combined sleep disorders in epilepsy patients is still unclear.In this paper,the relationship between epilepsy and sleep disorders in epilepsy patients was summarized,which involves multiple aspects such as the possible mechanism of combined sleep disorders,the common features of sleep disorders,the possible mechanism of sleep abnormalities in different epilepsy syndromes and the characteristics of sleep structure,the effect of antiepileptic drugs on sleep architecture abnormalities and its role in combined sleep disorders.

Eighty simple obesity patients were treated by electoacupuncturing Tianshu(ST 25), Shuidao(ST 28), Shuifen(CV 9), Guanyuan(CV 4), Daheng(SP 15), Huaroumen(ST 24),Daimai (GB 26), Quchi(LI 11), Hegu(LI 4), Liangqiu(ST 34) and Zusanli(ST 36). The results showed remarkable effect in 14 cases, middle effect in 38 cases, common effect in 23 cases and failure in 5 cases.

Objective To investigate the characteristics of rifampin(RFP) and isoniazid(INH) resistance genes of Mycobacteri-um tuberculosis in Ganzhou region .Methods Gene chip technology was employed to detect common resistance genes in 130 sputum samples with smear positive acid-fast staining and Ct values less than 30 .Results Among 130 samples ,34 samples(26 .2% ) were found resistance ,including 30 samples(23 .1% ) resistant to RFP ,26 samples(20 .0% ) resistant to INH ,and 21 samples(16 .2% ) resistant to both .The mainly mutation of RFP resistant gene was rpoB gene 531(C→ T ) ,accounting for 42 .4% ,while the mainly mutation of INH resistant gene was katG gene 315(AGC→ACC) ,accounting for 65 .4% .Conclusion The mutation charateristics of RFP and INH resistance-associated genes of Mycobacterium tuberculosis in Ganzhou region is consistent with domestic and foreign research .
