Chinese Journal of Primary Medicine and Pharmacy 2010;17(10):1316-1317
Objective To observe the clinical efficacy of interleukin2 (IL-2 ) in the treatment of children with recurrent respiratory tract infection( RRTI). Methods 160 children with RRTI from Mar 2005 to June 2008 in our hospital were divided into experimental group (n =80) and control group (n =80) randomly. IL-2 was given by hypodermic injection in experimental group and the other was treated with oral transfer factor. Then the clinical efficacy in two.groups was observed. Results The effects in the experimental group were superior to those in the control group(P <0.01). Conclusion IL-2 could enhance immunity and reduce the incidence rate of RRTI in children patients. The effects were superior to those patients treated with oral transfer factor.

Objective To explore the importance of diabetic education and hypoglycemia nursing for population with high risk of hypoglycemia through analysis of the personal factors influencing incidence of hypoglycemia of type 2 diabetic patients during initial use of insulin.Methods There were 257 cases of T2DM hospitalized patients during initial use of insulin,among whom 80 experienced hypoglycemia.They were divided into two groups,one was the hypoglycemia group,another was the non-hypoglycemia group.Firstly,we compared the different characteristics of the two groups such as gender,BMI and HbAlc,and so on.And then,the possible risk factors of hypoglycemia were analyzed by a Logistic regression model.Finally,the most significant factors were analyzed with the ROC curve.Results These two groups were obviously different in seven elements such as BMI,Scr,HbAlc and TG,and so on.BMI and HbAlc were the most primary causes for prevention of hypoglycemia.When patients got HbAlc<8.65% or BMI<26.3 kg/m2,they had more opportunity to occur hypoglycemia.Conclusions BMI and HbAlc of patients are primary causes for hypoglycemia.It is of great significance for nurses to enhance diabetes education to the patients with HbAlc<8.65% or BMI<26.3 kg/m2 to alleviate the incidence of hypoglycemia.

Objective To investigate the effect of intensive control of residual amount in stomach on prevention of ventilator associated pneumonia(VAP)during the process of enteral nutrition. Methods 96 patients with mechanical ventilation(MV) more than 48 hours were randomly divided into the case group and the control group, they were treated with intensive control and common control of residual amount in stomach respectively. The incidence rate of VAP, mortality rate, time of ventilation and hospitalization time were compared between the two groups. Results The incidence rate of VAP was 20.83% in the case group and mortality rate was 18.75%,the time of MV was(15.21±2.36)days, the hospitalization time was(22.38±12.34)days. The incidence rate of VAP wag 39.58%.mortality rate was 39.58%,the time of MV wag(19.85±4.58)days, the hospitalization time was(29.46±15.24)days in the control group. Conclusions Intensive control of residual amount in stomach could be helpful to decrease the incidence of VAP and mortality rate of patients with mechanical ventilation using nasal feeding, also shorten the time of MV and the hospitalization time.

Objective To estimate brain grey matter volume changes and location of abnormal brain regions cerebrum in early stage of bipolar disorder I (BD),in order to provided objective basis for diagnosing early stages BD.Methods 1 7 cases of BD with duration less than 2 years and 1 7 normal controls were recruited in this study.The volumetric difference of grey matter between two groups were analyzed by using voxel-based morphometry(VBM)software.Statistical threshold was voxel> 100,P <0.001 (uncor-rected).Results Compared to the normal controls,the grey matter volume of BD patients decreased in the left dorcial anterior cingu-late cortex(ACC),left insular,right sub-genu ACC,left superior temporal cortex,bilateral hippocampus-parahippocampus-amydala and left posterior lobe of cerebellum(P <0.001).Conclusion The grey matter volume of early stage BD patients is decreased,main-ly locating in the bilateral limbic system,the superior temporal gyrus and the cerebellar cortex,which probably is the morphological appearance of pathomechanism in early stages of BD.

Objective To explore the effects of graphene oxide (GO)-polyethylene glycol (PEG)-folic acid (FA)-pyrenemethylamine hydrochloride (PyNH2)-mediated RNA interference (RNAi) of hypoxia-inducible factor-1α (HIF-1α) on the biological behaviors of human pancreatic cancer Patu8988 cells.Methods GO-PEG-FA-PyNH2 and RNAi targeting HIF-1α gene (GO-PEG-FA-PyNH2-HIF-1α-RNAi)was constructed.The expressions of HIF-1α and glucose transporter 1 (Glut-l) in Patu8988 cells were determined after knockdown of HIF-1α by RNAi.The invasive ability,the proliferation and the cell cycle of Patu8988 cells were investigated.The effect of HIF-1α knockdown on the uptake of 18F-fluorodeoxyglucose (FDG) in Patu8988 cells was also detected.Comparison of data was conducted by one-way analysis of variance and least significant difference t test.Results The GO-PEG-FA-PyNH2 was successfully constructed,and no cytotoxicity was found.Under the hypoxia or normoxia state,the mRNA and protein levels of HIF-1α and mRNA level of Glut-1 in cells transfected with GO-PEG-FA-PyNH2-HIF-1α-RNAi (study group) were lower than those in cells transfected with GO-PEG-FA-PyNH2 (negative group) and cells transfected with Opti-minimal essential medium (Opti-MEM,control group;F=30.25-32.58,t=3.66-5.81,all P<0.05);the numbers of migrated cells in the study group were much lower than those in the negative group and the control group (F=38.63 and 41.35,t=20.51-35.25,all P<0.01);the cell proliferation in the study group was significantly lower than that in the negative group and the control group (F=35.19 and 38.11,t =15.11-22.19,all P<0.05).The proportions of G0/G1 cells in the study group were higher than those in the negative group and the control group (F=34.60 and 34.83,t=11.55-34.56,all P<0.05);the 18 F-FDG uptake in the study group was lower than that in the negative group and control group (F=29.85 and 31.69,t =3.35-4.35,all P<0.05).Conclusion GO-PEG-FA-PyNH2-mediated HIF-1α RNAi inhibits the expression of HIF-1α in pancreatic cancer cells,leading to changes in related biological behaviors.
