Objective To discuss effect of centralized training of basic operational skills for nursing students before nursing practice. Methods 176 student nurses in 2007 were set as the control group,320 nursing students in 2008 as the experimental group. The control group began practice after routine pre -practice education, based upon this, the experimental group carried out centralized training of basic operational skills for one week, only those who passed the examination could began practice, those who failed the examination should continued the training till they passed the examination. Time cost to master the operational skills, operational assessment results and evaluation of nursing practice by teachers were compared between the two groups. Results Compared to the control group, time cost to master the operational skills shortened, operational assessment results and evaluation of nursing practice by teachers improved in the experimental group. Conclusions Through centralized training of basic operational skills, time cost to master the operating skills of basic nursing by nursing students shortened, operational capability of nursing students can be improved, and the clinical nursing teaching quality can be promoted.

Objective To study the expression and clinical significance of matrix metalloproteinase 2 (MMP-2) in chinese patients with bladder cancer. Methods The relevant original articles published in journals from 1998 to 2014 were selected. The ratio of the case group and the control group (OR value) regarded as an effect index. Then the original data were analyzed using Meta analysis software RevMan 5.0, the combined OR values and 95%confidence interval were calculated, and the forest map was draw. Results 13 studies involving 692 patients that met the inclusion criteria were included in the Meta analysis. The OR values of bladder cancer tissue group and normal bladder tissue group, superficial bladder cancer group and invasive bladder cancer group, and low grade bladder cancer group and senior bladder cancer group were 45.83, 0.22 and 0.31, respectively. The positive rates of MMP-2 in bladder cancer tissue group, invasive bladder cancer group and advanced bladder cancer group were significantly higher than those in normal bladder tissue group, superficial bladder cancer group and low grade bladder cancer group (all P< 0.05). Conclusions The high expression of MMP-2 has a certain effect in bladder cancer. The detection of MMP-2 contributes to the understanding of the biology of bladder cancer, and provides information for clinical treatment and prognosis.

Objective: To observe the effect of electroacupuncture (EA) on the electrogastrogram and gastric antrum ghrelin in rats with diabetic gastroparesis (DGP). Methods: Fifty Sprague-Dawley (SD) rats were randomly divided into group A, group B, group C, group D and group E, 10 rats in each group. Group A was the blank control group without intervention. Group B, Group C, Group D and Group E were treated with single dose intraperitoneal injection of 2% streptozotocin (STZ), combined with 8-week high glucose and high fat diet to establish DGP rat models. Group B was the model group without treatment. Group C was the EA at acupoint group, was treated with EA at Zusanli (ST 36), Liangmen (ST 21) and Sanyinjiao (SP 6). Group D was the EA at non-acupoint group, was treated by EA at the control points of Zusanli (ST 36), Liangmen (ST 21) and Sanyinjiao (SP 6). Rats in the metoclopramide control group received 1.7% metoclopramide solution [10 mL/(kg·bw)] by gavage. Rat's blood glucose level was measured by blood glucose meter; gastric emptying rate was detected using phenol red as a marker; the electrogastrogram was detected by BL-420F biological function system; the protein level of ghrelin was detected by enzyme-linked immunosorbent assay (ELISA); the expression of ghrelin mRNA was detected by real-time polymerase chain reaction (RT-PCR). Results: Compared with group A, the blood glucose of group B, C, D and E were significantly increased before and after the treatment (all P<0.01); after treatment, the gastric emptying rate of group B was significantly decreased (P<0.01), the migration rates of small intestine in group B, C, D and E were significantly lower (all P<0.01), and the protein content of ghrelin in group C was significantly decreased (P<0.01); the expressions of ghrelin mRNA were significantly increased in group B, C, D and E (all P<0.01), the mean amplitudes of electrogastrogram in group B and D were significantly decreased (both P<0.01). After treatment, compared with group B, the blood glucose of group C was significantly decreased (P<0.05), the gastric emptying rate and small intestine migration rate were significantly increased in group C and E (P<0.05, P<0.01), the small intestinal migration rate was significantly increased in group D (P<0.05), the expression of ghrelin in protein and mRNA in group C was significantly lower (P<0.01), the expression of ghrelin mRNA in group E was significantly lower (P<0.05), and the mean amplitude of electrogastrogram in group C was significantly increased (P<0.05). After treatment, compared with group D, the protein and mRNA expressions of ghrelin in group C were significantly decreased (P<0.01). After treatment, compared with group E, the protein expression of ghrelin in group C was significantly decreased (P<0.01). Conclusion: EA at Zusanli (ST 36), Liangmen (ST 21) and Sanyinjiao (SP 6) could regulate the blood glucose level of DGP model rats, enhance electrogastrogram activity, promote gastric emptying, and regulate ghrelin expression in protein and mRNA.

OBJECTIVETo explore the risk factors, and control measures of cytomegalovirus (CMV) infection after hematopoietic stem cell transplantion (HSCT) in children with primary immunodeficiency diseases(PID).

METHODSWe retrospectively analyzed results of 26 patients with PID-Wiskott-Aldrich syndrome (WAS, n=20), severe combined immunodeficiency (SCID, n=1) , X-linked chronic granulomatous disease (XCGD, n=2) and X-linked hyper-immunoglobulin M (IgM) syndrome (XHIM, n=3)-who underwent HSCT from June 2007 to December 2012 in our center. Serologic studies (ELISA) and weekly CMV infection surveillance (quantitative PCR, qPCR) were routinely performed before and after HSCT. Ganciclovir or forcarnet was used for pre-emptive and curative therapy.

RESULTSAll 26 patients were male with the median age at HSCT of 27 months (range 7-77 months). At a median follow up of 24 months (range 5-66 months), the 5-year overall survival rate was (75.0 ± 9.0) %. CMV infection occurred in 42.3% (11 of 26) of the patients, two of them developed CMV interstitial pneumonia (CMVIP). Univariate analysis revealed that the incidence of pre-transplant CMV infection between with and without CMV activation groups after HSCT was significantly different (62.5% vs 10.0%, P=0.010). Additional variables not associated with CMV infection were stem-cell sources, donor type, HLA disparity and acute GVHD (all P values>0.05).

CONCLUSIONCMV infection was a major complication of HSCT. Sensitive monitoring, early diagnosis, timely treatment may improve the survival rate for these PID undergoing HSCT.
