Objective To explore the effect of discharge planning mode on growth and development in prematures.Methods 62 premature cases were randomly divided into the control group and the observation group with 31 cases in each group respectively.The control group accepted routine nursing care,the observation group was given comprehensive detailed discharge planning mode on basis of conventional premature nursing.All the research objects were monitored about the height and body weight,and also the Bayley Infant Development Scale was adopted to evaluate the psychological behavior development when their corrected gestational age was 3,6,12 months respectively.Results The height,weight and Mentality Development Index (MDI),Psychomotor Development Index(PDI) of the prematures in the observation group when their corrected gestational age was 3,6,12 months respectively were all higher than those of the control group.Conclusions Application of discharge planning mode in premature infants is helpful to the physical and mental developmental of them.

Objective To increase the normative follow-up rate of organ transplant recipients,and to improve their long-term survival rate of patients and their life quality.Methods Establish a normative follow-up management system of organ transplantation,improve the follow-up rules and link management,strengthen the whole-course health education and provide comfort and warm service for patients.Results ( 1 ) The results of patients/renal survival rates at different times indicated that the 1 year,3 year and 5 year patients/renal survival rates in the normative follow-up group were significantly higher than that in the random follow-up group,P ＜ 0.05.( 2 ) The 1-year follow-up results for the outpatients indicated that no difference in one-year follow-up rate were observed in both groups (98.4％ vs.97.5 ％,P =0.128).And the 3 year and 5 year follow-up rates in the normative follow-up group were statistically significantly higher than that in the random follow-up group (90.1％ vs.85.5％,88.3％ vs.55.3％,P ＜ 0.001 ).Conclusion Establishment of the sound and normative follow-up management system of organ transplantation was helpful to improve the long-term survival rates of patients and their life quality.

ObjectiveTo explore the causes and countermeasures for extravasation of intravenous fluids in children. Methods726 cases of intravenous infusion in pediatric surgery department from May to December 2011 in our hospital were observed. ResultsThere were 30 cases with extravasation of intravenous infusion in the 726 cases,the leakage rate was 4.13％.The specific causes of fluid extravasation included:younger age of children,not cooperating with the infusion in 18 cases,accounting for 60.00％,followed by non standardized fixation methods in 5 cases,accounting for 16.67％,and accompanying family members refused to be disturbed accounted for 13.33％,Nursing visits to owe in a timely manner accounted for 6.67％.The rate of younger age of children and lack of cooperation leading to fluid extravasation were significantly higher than other causes,the difference was statistically significant. ConclusionsChildren age,fixation method,cooperation of family members,inspections and other factors can be controlled.Along with the continuous improvement of medical standards and a variety of active and effective implementation of the measures,these factors can be controlled effectively.Strengthening the training of nurses and vocational skills to enhance their own sense of responsibility,to give standardized infusion operation and fixation,and give predictable observation and treatment,can effectively prevent the occurrence of extravasation of intravenous fluids.

ObjectiveTo explore the effect of JNK-c-Jun signal pathwayon connexin 43 (Cx43) expression and its role in renal tubular epithelial-myofibroblast transition (TEMT) induced by TGF-β1.Methods Normal rat kidney tubular epithelial cells(NRK-52E) were cultured in Dulbecco's modified eagle medium(DMEM) with 10％ fetal bovine serum,then were randomly divided into 3 groups: control group,TGF-β1 group (treated with TGF-β1 10 μg/L),and TGF-β1+SP600125 (selective JNK inhibitor,50 μmol/L) group. The protein expressions of JNK,c-Jun,α-SMA,Cx43 and E-cadherin were assayed by immunocytochemistry and Western blotting.The Cx43mRNA was assayed by RT-PCR.Gap junction intercellular communication(CJIC) was measured by fluorescence recovery after photobleaching assay(FRAP).Results TGF-β1increased the expressions of JNK,c-Jun and α-SMA(P＜0.05),reduced the expressions of Cx43 and E-cadherin (P＜0.05),and inhibited GJIC of NRK-52E(P ＜0.05).SP600125 could alleviate the above expressions changes and enhanced GJIC induced by TGF-β1.Conclusion JNK-c-Jun signal pathway induces TEMT ofNRK-52E treated with TGF-β1 viadown-regulation of connexin 43expression and inhibition of GJIC.

Objective To explore the correlation between cholecystectomy and colorectal adenoma.Methods A total of 981 patients who underwent colonoscopy between January 2007 to December 2012 at Wuhan Central Hospital were enrolled in the study according to the inclusion criteria.The patients were divided into cholecystectomy group (n=216) and control group(n=765) in terms of cholecystectomy or not.The incidence of colorectal adenoma ,gender ,age ,location and pathological type of ade-noma were analyzed in the two groups.Results Significant differences were noted in the incidence and location of colorectal ad-enoma ,and gender between the two groups (P< 0.05).The incidence of colorectal adenoma was higher in cholecystectomy group than in control group ;the number of female patients with colorectal adenoma was greater than that of male patients ;the incidence of proximal colorectal adenoma was higher than that of distal adenoma.But the average age of patients with adenoma was not significantly associated with the pathological types of adenoma in both groups (P>0.05).Conclusion Cholecystecto-my is closely associated with the occurrence of colorectal adenoma.Screening for colorectal adenoma should be considered in the patients with gall bladder removal.

Objective To investigate the value of quantitative TB‐DNA test ,interferon gamma release test and the detection of tuberculosis antibodies for the diagnosis of active pulmonary tuberculosis .Methods 51 patients were diagnosed as tuberculosis from 2013 July to 2014 June in the hospital ,whose sputum smear microscopy for acid fast bacilli were positive .Then TB‐DNA quantitative test ,interferon gamma release test (T‐SPOT .TB)and tuberculosis antibody detection were performed for those pa‐tients .All the result were retrospectively analysed .Results The positive rate of T‐SPOT .TB was 90 .1% ,the positive rate of quan‐titative TB‐DNA test was 74 .5% and the positive rate of tuberculosis antibody detection was 37 .3% .Conclusion Because the re‐sult of T‐SPOT .TB is not affected by the process of specimen collection ,it is the most sensitive test of the three tests at present , and has higher value in the auxiliary diagnosis of active pulmonary tuberculosis than the other two .

Objective To improve the diagnostic accuracy by analyzing the CT features of primary hepatic sarcoma.Methods The CT findings of 6 cases with primary hepatic sarcoma confirmed by histopathology were analyzed retrospectively,including primary hepatic angiosarcoma 2 cases,and epithelioid hemangioendothelioma,primary hepatic lymphoma,alveolar soft-part sarcoma,undif-ferentiated embryonal sarcoma,1 case each.Results Primary hepatic sarcoma appeared as multiple nodules with heterogeneous and progressive enhencement in one case,and a dominant mass with multiple satellite nodules in another case.Epithelioid hemangioendo-thelioma displayed as multifocal hepatic disease involving both liver lobes,more than half of the lesions were peripheral and extended to the liver margin.Primary hepatic lymphoma demonstrated as an ill-defined low-density lesion with irregular ring enhancement. Alveolar soft-part sarcoma presented as a well-defined low-density lesion with obviously heterogeneous enhancement in arterial phase.Undifferentiated embryonal sarcoma appeared as a huge cystic lesion with slightly margin enhancement.Conclusion The CT findings of primary hepatic sarcoma are associated with the pathological types,combining clinical symptoms with typical CT features are helpful to the diagnosis.The ultimate diagnosis relies on pathology and immune histochemistry.

ObjectiveTo investigate the role of Nav1.7 in dorsal root ganglia (DRG) in a rat model of diabetic neuropathic pain (DNP).MethodsThirty-two female Wistar rats aged 3 months weighing 180-220 g were randomly divided into 4 groups ( n ＝ 8 each):control group ( group C),sham operation group ( group S),DNP group and ProTx- Ⅱ (a selective Nav1.7 blocker) group (group E).Diabetes mellitus was induced by intraperitoneal streptozocin 65 mg/kg.Blood glucose level and mechanical paw withdrawal threshold (MWT)to von Froy filamentstimulation were measured 2 weeks later.DNP was confirmed by blood glucose level ≥ 16.0 mmol/L and MWT decreased by more than 50％ of the baseline value.Intrathecal catheter was implanted at L5,6 interspace on day 10 after successful induction of DNP.On day 4 after placement of the intrathecal catheter,ProTx- Ⅱ 10 μg/kg was injected intrathecally in group E,while the equal volume of normal saline was given in groups DNP and S.MWT and never conduction velocity (NCV) were measured 1 h after intrathecal injection.The rats were then sacrificed and DRGs of the lumbar segment (L4-6) were removed for determination of Nav1.7 protein expression (by immuno-histochemistry and Western blot) and Nav1.7 mRNA expression (by RT-PCR).ResultsThe MWT and NCV were significantly lower and the Nav1.7 mRNA and protein expression was significantly higher in groups DNP and E than in group C.ProTx- Ⅱ significantly attenuated the diabetes-induced changes in MWT,but had no effect on NCV and Nav1.7 mRNA and protein expression.ConclusionNav1.7 in DRG is involved in the maintenance of DNP in rats.

Objective To investigate perioperative nursing of respiratory system in severe scoliosis patients.Methods 26 severe scoliosis patients with respiratory function training before operation were retrospected.All of them tested pulmonary function before and after training,postoperative respiratory system nursing were also taken to maintain airway unobstructed,including respiratory rate and oxygen saturation monitoring,effective pain management and respiratory complications controlling.Results The average forced vital capacity(FVC)was 45.9%and 52.1%before and after breathing exercises,the mean forced expiratory volume in one second(FEV1)was 43.8%and 48.8%before and after breathing exercises,with lung function improvement in 69.2%patients. There were two hemopneumothorax and three mild or moderate pleural effusion occurred within 10 days after surgery,but all recovered after effective treatment and nursing.Conclusions Perioperative systematic and effective training in respiratory function and airway management can improve lung function and surgical safety,reduce the incidence of postoperative pulmonary complications,and promote early rehabilitation .
