Objective: To investigate the effect of helper T cells (Th1 and Th2) and its important significance in judging prognosis of patients with advanced lung cancer. Methods: Interferon-? (INF-?) and interleukin-4 (IL-4) in plasma and pleural effusion were detected by enzyme-linked immunoassay in patients with advanced lung cancer, IFN-? and IL-4 reflected activity of Thl and Th2 respectively. Results: The activity of Th1 in patients with advanced lung cancer was lower than that in normal persons in peripheral blood. For non-outstanding curative effect or progressive state of illness, the activity of Thl in patients of above 1 year survival time decreased in post-treatment than in pretreatment, the activity of Th2 increased in post-treatment. Conclusion: Activity of Helper T cells ( Th1, Th2 ) could be an important marker to diagnose lung cancer and judge prognosis in patients with advanced lung cancer.

Objective:To observe therapeutic effect of continuous renal replacement therapy (CRRT ) on different types of cardiorenal syndrome (CRS) .Methods :According to patient′s conclition ,a total of 247 CRS patients were divided into type 1 group (n=47) ,type 2 group (n=51) ,type 3 group (n=55) ,type 4 group (n=49) and type 5 group (n=45) .All patients received CRRT ,echocardiography and plasma level of N terminal pro B type natriuretic peptide (NT‐proBNP) detect to evaluate cardiac function status ;the 24h urine volume and endogenous creatinine clearance rate (Ccr) were measured to assess renal function status before and after treatment . Results:Compared with before treatment ,on one week after CRRT ,LVEF ,urine volume and Ccr level significantly rose ,NT‐proBNP level significantly reduced ( P<0.05 or <0.01) .Compared with type 4 and 5 group ,there were significant rise in LVEF [ (48.98 ± 1.55)% ,(44.67 ± 1.48)% vs .(55.13 ± 4.27)% ,(53.73 ± 3.52)% ,(57.95 ± 2.89)% ] ,urine volume [ (1118.83 ± 168.09 ) ml , (1125.47 ± 177.28 ) ml vs .

(2137.51 ± 123.59) ,(2421.12 ± 121.22) ,(2139.81 ± 147.28)] in type 1 ,2 and 3 group ,P<0.05 all .Conclusion:CRRT is effective on different types of CRS ,but it′s best on type 1~3 than those of type 4~5 , which may be re‐lated to different pathological mechanisms of CRS different types .

Objective To study changes of urinary protein in premature infants after asphyxia in order to explore influence of asphyxia on the renal function. Methods Microalbumin(mAlb),retinal-bindingprotein (RBP) ,N-acety-?-D-aminoglucosidase in urine and serum urea nitrogen(BUN),creatinine(Cr) were performed in 56 normal premature infants and 49 asphyxia ones with immunoturbidimetric method, ELISA method, rate method , enzymic method and picric acid method when they were 1,4,7 day age after born. Results (1)With ages increasing urinary mAlb took on decreasing trend in the same gestation age but there was no different while with the gestation age increasing in the same ages urinauy mAlb was decreased significantly (P

Objective To discuss the nursing care for patients with placenta previa,who receive uterine arterial catheterization and embolization in the second trimester of pregnancy. Methods By using superselective catheterization with Seldinger technique,bilateral uterine artery angiography and embolization were performed in 16 patients with placenta previa in the second trimester of pregnancy. Two to four hours after the procedure,rivanol intra-amniotic injection was employed to induce the abortion. Close perioperative observation and careful nursing were carried out. Results The fetus with its subsidiary tissue was delivered in a mean time of 4.5 hours after the operation in 15 cases. No postpartum hemorrhage occurred. Induced abortion failed in one case with 26 weeks pregnancy because of a scar uterus and cervical dystocia. Hysterotomy was performed 6 days later,blood loss during the operation was about 100 ml. No nursing care related complications occurred in all 16 patients. Conclusion Uterine arterial embolization is very helpful in making the induced abortion for the treatment of bleeding placenta previa in the second trimester of pregnancy. Strengthening of perioperative care can improve successful rate of interventional therapy and prevent the occurrence of complication.

BACKGROUND:Mesenchymal stem cells have a extreme prospect in orthopedics, which show great potential especially in the treatment of articular cartilage defect disease. Bone marrow is the main source of mesenchymal stem cells, and the iliac puncture is a conventional way to obtain bone marrow, but is restricted by the limited resources and strict technical requirements. Therefore, it is of great significance to explore new effective and convenient sources of mesenchymal stem cells. OBJECTIVE:To explore the feasibility of autologous mesenchymal stem cells derived from the joint drainage fluid after knee arthroscopy.METHODS: We selected eight patients who underwent arthroscopic surgery to collect joint drainage fluid by pre-made sterile blood bag before the wound closure. Precipitation with hydroxyethyl starch and density gradient centrifugation method were performed to isolate and culture mesenchymal stem cells from the joint drainage fluid. Cell morphology, growth curve, surface marker identification were observed and detected using flow cytometry. Then, adipogenic, chondrogenic and osteogenic differentiation of cells were induced and identified by oil red O, toluidine blue staining, and alizarin red staining, respectively. RESULTS AND CONCLUSION:The cultured cells were spindle-shaped, adherently grew and had good proliferation ability, which were positive for CD44, CD90, CD105 and CD73, but not for CD45. Under standard inductions, the cultured cells were induced to differentiate into osteoblasts, adipocytes and chondrocytes. Therefore, these cells were confirmed as mesenchymal stem cells. Mesenchymal stem cells were successfully isolated from the joint drainage fluid of eight patients and had no difference in cell morphology, proliferation and phenotypes. To conclude, the joint drainage fluid is an ideal source of mesenchymal stem cells with the guaranteed quality and quantity.

ObjectiveTo investigate the effects of task-driven teaching mode on physical therapy teaching in higher vocational education. Methods40 students in 2006 rehabilitation class were taught with routine mode as the control group, while 35 students in 2007 rehabilitation class taught with task-driven mode and routine mode as experimental group. ResultsAt the end of the course, the results of examination in theory and practice were better in the experimental group than control group (P<0.01). 85.71%～94.28% students in the experimental group said that the task-driven teaching mode could improve their comprehensive quality especially the skill of practice, as well as the interest and ability of learning. ConclusionTask-driven teaching mode can improve the teaching effect on physical therapy, and received by most of the students.

This article introduced the reform of the teaching mode for Rehabilitation Therapy in higher vocational education, including the course of theory and practice, system of personnel training and assessment.

Objective: To investigate the changes in serum CD44v6/v EGF(sCD44v6/sVEGF)levels after concurrent chemoradiotherapy in patients with inoperable non-small cell lung cancer(NSCLC)patients and to analyze the correlation of serum markers with patients'prognosis. Methods: The sCD44v6/v EGF levels were detected by ELISA in 50 inoperable NSCLC patients before and after concurrent chemorediotherapy. Results: The sCD44v6 and sVEGF levels before treatment was significantly higher than that in the control group.The pre-treatment sVEGF level was closely related to cTNM stage.metastasis,cell differentiation and primary tumor size,but was not correlated with histological classification,lymph node status,age or gender.The pre-treatment sCD44v6 level was closely correlated with cTNM stage,metastasis,cell differentiation,and primary tumor size,but was not correlated with histological classification,age or gender.Patients'sCD44v6 before treatment(570.89±63.30 ng/L)was significantly higher than that after treatment(281.44±74.28 ng/L).Patients'sVEGF before treatment(241.09±85.96 ng/L)was significantly higher than that after treatment(133.64±67.69 ng/L).PD patients had the highest level of sCD44v6 and sVEGF and CR patients had the lowest sCD44v6 and sVEGF level.The sVEGF level was highly correlated with sCD44v6(r=0.291,P<0.05).Conclusion:The sCD44v6 and sVEGF levels might be helpful for evaluation of the biological behavior and prognosis of NSCLC.
