Gastric cancer(GC) is deeply threatening the health of our people, the mortality rate of GC is the second death cause of carcinoma i n our country. Since the lack of special clinical symptom at the early state of GC, detecting GC at the molecular biological level is expected to diagnose early gastric cancer. This article discusses some markers such as PCNA, p53, telomera se, ras protein and so on to assess the possibility of diagnosing the early gas tric cancer with these molecular biological markers. According to analyzing rela ted papers published, PCNA and p53 were found to be the molecular biological mar kers which should be firstly taken into account in diagnosing gastric cancer. Bo th of them can be easily detected by using immunohistochemical method. Telomeras e is also a good marker, but because of its difficult technology and high cost, it is not so practicable as the former two as the diagnostic marker of early gas tric cancer. Besides, ras potein can also be taken into account as the early det ecting auxiliary marker for GC.

Sport fatigue affects exercise ability of human being.A number of experiments of animals and humans have proved that the rational usage of nutritional supplementation will eliminate the fatgue caused by over-exerise,and improve exerise ability.This review is about the effect of the nutritional supplementation in eliminating sport fatigue.

AIM: To study the effects of fructose-1,6-diphosphate (FDP) on adriamycin (ADR)-induced calcium and sarcoplasmic reticulum Ca 2+-ATPase activity in cardiomyocytes of rats. METHODS: Rats were treated with ADR by intraperitoneal injection (2 5 mg?kg -1 body weight) once every two days for 11 days, and then ADR-treated rats were intervened by FDP at different dosages (ip) once every other day for 41 days. Enzyme linked immune absorption assay (ELISA) was employed to detect froponin I (CTnI). CK-MB was examined by monoclonal antibody. Intracellular free calcium concentration was measured on fluorescent spectrophotometry and SRCa 2+-ATPase activity was examined by inorganic phosphate. RESULTS: FDP (300, 600, 1 200 mg?kg -1) significantly reduced the levels of CTnI and CK-MB in serum. Decreased calcium and increased SRCa 2+-ATPase activity in cardiomyocytes were also observed when ADR-treated rats were intervened by FDP (P

Objective To explore the diagnostic value of transbronchial lung biopsy(TBLB), CT-guided percutaneous lung biopsy and sputum cytology for unknown lung mass. Methods The clinical data of 101 inpatients with unknown lung mass were retrospectively analyzed. Results Among the 101 cases, 73 cases underwent fibrous bronchoscopic examination, 18 cases underwent CT-guided percutaneous lung biopsy, and 10 cases underwent both of them.The diagnostic coincident rate of the two methods was 70%. 54 cases were diagnosed lung carcinoma by pathology. The sensitivity and specificity of TBLB for diagnosing central type of tumor were 88% and 100%, respectiely, and those for diagnosing peripheral type of tumor were 43% and 100%, respectively. The sensitivity of CT-guided percutaneous lung biopsy was 80%,while the specificity was 100%. Complication frequency in the CT-guided percutaneous lung biopsy was 22%, and much higher than that (12%) in the TBLB. Only 30% cases underwent sputum cytology examination, and the positive rat was 6%. Conclusion Sputum cytologic examination is a convenient and cheap method, but its diagnostic rate is relatively low. TBLB was the first choice for examining central type of lung mass. For the peripheral type of lung mass, examination method was selected based on the location and size of the mass.

The scientific research of education is a kind of activity in which we discover and reveal the unknown educational phenomenon, the essence and rule of it. As question study is the key of the educational research, then the quality and success of scientific research have to depend on whether a true question can be found or not. In the following article, I first analyzed the concept of Question? Secondly , based on the traditional standpoint of Theory of Truth and the viewpoints of some scholars, what was true question was discussed. Finally I made a primary analysis of true question.

The necessities and feasibilities of setting up of community nursing specialty for baccalaureate program in nursing college and university are discussed. And the cultivating approach from aspects of training target; training mode, curriculum design and training of community practical abilities is explored.

Objective To explore the application effect of problem-discuss-guidance(PDG) teaching model in rehabilitation medicine Teaching.Method Class A(141 students) was taught with traditional teaching model in ChapterⅡ,while PDG teaching model was adopted in Chapter V.Class B(150 students) was taught with PDG teaching model in chapterⅡ,while traditional teaching model was adopted in Chapter V.to compare teaching result of the two teaching model.Result The questionnaire scoring and the performance of the classroom test and the scoring rate in this section of Final Examination of PDG teaching model were obviously superior to traditional teaching model(P

OBJECTIVE:To provide reference for rational application of TCM injection. METHODS:The utilization of TCM injection in our hospital during 2011-2014 was analyzed in terms of species,consumption sum,DDDs and DDC,etc. RESULTS:The type and consumption sum of TCM injection kept stable in our hospital during 2011-2014. TCM injection for activating blood circulation to dissipate blood stasis as Shuxuetong(Heilougjiang),Danhong,Shuxuening took up the front of consumption sum in 4 years. Top 3 TCM injections in the list of DDDs were Shuxuetong,Shuxuening(Heilougjiang), Danhong/Xueshuangtong corre-sponded to consumption sum. DDC of TCM injection were kept around 100 yuan. DUI ratio of TCM injection were almost equal to 1 or close to 1. CONCLUSIONS:The amount and DDDs of TCM injection are synchronous in our hospital,and the utilization of TCM injection is stable and rational basically in our hospital. TCM injection with suitable price and definite efficacy take up a large share,and the amount of TCM injection for clearing away heat and toxic material with anti-inflammatory effect increase rapidly.

Objective To solve the problems of Information Island and Repeated Construction in hospital information construction. Methods Some solutions of application system integration were discussed and architecture systems were proposed. Results Integration mode was adopted according to the condition of the hospital. Conclusion References are provided for the integration of hospital information system.
