Objective To compare the graft function of 2 methods of kidney harvesting,the modified method of combined liver and kidney procurement and rapid en bloc kidney procurement. Methods The clinical data of 220 cadaveric renal transplantation recipients were collected(12 months follow-up),174 cases from en bloc kidney procurement and 46 from combined liver and kidney procurement.The average harvesting time,the incidence of renal vein injury,1 year kidney survival and incidence of acute rejection were compared between the two methods.Results In average harvesting time and incidence of renal vein injury,the en bloc kidney procurement were better than the method of combined liver and kidney procurement.However,the method of combined liver and kidney procurement was better than the en bloc kidney procurement in 1 year kidney survival,1 year incidence of acute rejection and average warm ischemia time.There was no difference in 1 year survival of patients and 24 h,1 week and 1 year graft function after transplantation. Conclusion Although the method of combined liver and kidney procurement is better than the en bloc kidney procurement in 1 year kidney survival and 1 year incidence of acute rejection,there is no difference between the 2 methods in 1 year survival of patients and graft function after transplantation.

Objective:To study the relationships of portal hypertensions to vasoactive substances-angiotensin(AT-Ⅱ)in cirrhosis patients.Methods:48 patients with liver cirrhosis(LC)(including 18 patients with compensated LC and 30 patients with decompensated LC) and 32 normal controls(NC) were studied. Color duplex doppler ultrasonography was used to study portal venous and splenic venous blood flow(PVBF and SVBF).Also,the blood concentration of AT-Ⅱ was detected.Then,analyze the correlation between PVBF and SVBF to AT-Ⅱ.Results:Portal hyperdynamic exists in cirrhosis patients from beginning to the end. Low level of AT-Ⅱ in compensated LC patient has no relation with portal hyperdynamic, high level of AT-Ⅱ in decompensated LC has positive relation with portal hyperdynamic.Conclusion:This study has directed significance of clinical treatment and diagnosis.

Objective To investigate the efficacy and safety of anti CD25 Ab (Zenapax;Daclizumab) induction therapy in 62 patients following renal transplantation. Methods Sixty-two renal transplant recipients treated with Daclizumab induction therapy were analyzed retrospectively from Sep. 1999 to May 2004. Main immunosuppressive therapy regimen consisted of steroids cyclosporine and mycophenolate mofetil in all recipients after operation. According to Daclizumab dosage, these recipients were divided into 1-dose group, 2-dose group and over 2-dose group. All patients received Daclizumab 1 h before operation.Results The patients subject to Daclizumab were followed up from 3 months to 57 months. Seven of them had acute rejection ( 11.3 %) at intervals for 10.3 months, from 2 months to 14 months. Patient who had acute rejection at 10th month after operation lost his graft at 13th month after transplantation for graft dysfunction. The incidence of acute rejection was 15.6 % among 45 patients followed up over 12 months. Conclusions Induction therapy of Daclizumab could decrease the incidence of acure rejection, delay the time of acute rejection and relieve the severity of rejection. More graft can be long-survival. We can lower the dosage of CsA effectively and safely after induction of Daclizumab.

Objective To evaluate the effects of positive end-expiratory pressure (PEEP) targeting optimal oxygenation on local gas distribution and inflammation in dogs with acute respiratory distress syndrome (ARDS). Methods ARDS was induced by saline alveoli-lavage and oleic acid intravenous. The animals were mechanical ventilated 4 h at optimal PEEP titrated by oxygenation. Computed tomography (CT) scans were performed before and after induction of ARDS and at the end the study. NF-κB was measured by electrophoretic mobility shift assay (EMSA), IL-6 and IL-10 were assessed by ELISA.Myeloperoxidase (MPO) and malondialdehyde (MDA) were measured. Pathological changes were examined under optical microscope. Results (1) Compared to baseline, total lung volumes decreased and nonaerated areas increased significantly after the induction of ARDS in both groups (P ＜ 0.05 ). Compared with ARDS models, PEEP titrated to achieve optimal oxygenation resulted in greater lung recruitment but was accompanied with hyperinflation, hyperinflation occurred in non-dependent lung. Compared with oleic acidinjured ARDS, the changing of hyperinflated lung areas was increased markedly in saline lavage-injured ARDS (P＜0.05). (2) Compared with right lung ventral lower lobe, lung injury score was lower in right lung upper lobe. Histological injury in right lung dorsal lower lobe was severer than that in right lung upper lobe and right lung ventral lower lobe. NF-κB activation of right lung dorsal lower lobe was markedly higher than right lung upper lobe (P ＜ 0.05 ). MPO and MDA were much higher with right lung dorsal lower lobe than right lung upper lobe and right lung ventral lower lobe ( P ＜ 0.05 ). Compared with right lung upper lobe and right lung ventral lower lobe, IL-6 and IL-10 increased markedly in right lung dorsal lower lobe ( P ＜ 0.05 ). Conclusions Alveolar hyperinflation and aggravated lung injury in non-dependent region were occurred at PEEP targeting optimal oxygenation. Hyperinflation was more common in saline lavage-injured ARDS.

Objective To investigate the detection and treatment of carry-over of automatic biochemistry analyzer. Methods We detected the sample carry-over by determining one high level quality control serum and three zero levels serum continuously in five days. We used mixed patients serum to detect the carry-over come from reagent probe, muddler and cuvette by arranging test sequence of different item, combination and the times of rerun. We also used different methods such as immersion, cleaning probe, extended priming to handle the reagent carry-over.Results The sample carry-over was -0.37%～0.48% on new analyzer and 0.51～1.17% on old analyzer, respectively. The carry-over of CHO, TG, HDL on reagent probe and muddler of TBA was 86.9%～208.7% and 86.0%～256.5% on old analyzer, respectively. There was no reagent carry-over among other items on old analyzer. There was no carry-over on reagent probe on new analyzer, the carry-over of different items on cuvette of TBA was -0.9%～1.7%. After immersion, cleaning and extended priming, the carry-over of CHD, TG, HDL on TBA reagent probe fell to -1.1%～2.7% and -0.07%～0.09%, respectively.Conclusions The methods which have been mentioned above can detect the sample and reagent carry-over. The carry-over can be reduced by immersion, cleaning, extended priming and testing in different unit.

Objective To determine the relationship between the viral load of cerebrospinal fluid (CSF) and sensorineural hearing loss (SNHL) in newborns with symptomatic congenital cytomegalovirus (CMV) infection.Methods The study cohort comprised 36 newborns with symptomatic congenital CMV infection.CSF from all of the patients were analyzed for the presence of CMV DNA by PCR.Audiological function were performed on them by brain stem auditory evoked potential at birth,at 6 and 12 months of age.Results (1)Of the 36 newborns,15 cases (41.7％) had positive CSF PCR result,17 cases (47.2％) had SNHL.(2) The prevalence of SNHL in the group of newborns with positive CSF PCR result was 60.0％ (9/15),and it was 38.1％ (8/21) in the group of newborns with negative CSF PCR result,there was no significant difference of the prevalence of SNHL between the two groups (P =0.194).(3) In newborns with positive CSF PCR result,the amounts of CSF CMV DNA was not different between the newborns with SNHL and normal hearing (3.35 ± 0.68 vs.3.17 ± 0.56,P =0.36).Conclusion A positive CSF PCR result and the CMV viral load of CSF did not correlate with SNHL.

Objective To study the effect of hidden curriculum on the professional value of nursing students in higher education.Methods A total of 300 full-time nursing students in higher education were collected by the cluster sampling method.They were divided into experimental group and control group by natural class lottery method with 150 students each.The students in experimental group accepted the hidden curriculum such as administrator working of nursing students training,simulated the candidates and the volunteer activities.Then the professional value of the 2 groups was evaluated with nursing professional value questionnaire.Results The total score of the professional value in experimental group after intervention was (126.38±3.29) scores,and caring was (32.50±1.20) scores,trust was (24.40±1.59) scores,justice was (25.54±1.55) scores,profession was (19.64±1.26) scores and behaviorism was (24.31±1.30) scores.The total score of the professional value in control group after intervention was (123.62±2.76) scores,and caring was (32.51±1.24) scores,trust was (22.36±1.30) scores,justice was (26.47±1.54) scores,profession was (19.80±1.23)scores and behaviorism was (22.54±1.59) scores.The scores of trust and behaviorism in experimental group were higher than those in control group,and there were significant differences,t=2.813,2.441,P＜0.05.Conclusions Nursing students of college have positive professional values.The hidden curriculum can cultivate the nursing students' trust and positive psychological quality in higher education.And thus it can be reasonably used in teaching,which would produce a more proactive effect in higher education.

It is confirmed that chronic atrophic gastritis (CAG) caused by Helicobacter pylori is the main cause of gastric precancerous lesions.CAG is also the key determinant in gastric cancer risk assessment,which affects pepsinogen and gastrin-17 secretion.Most of the gastric cancer patients have poor prognosis,and non-invasive tools for gastric cancer screening and diagnosis are lacking.Therefore,the early detection of gastric cancer in order to reduce the disease mortality is necessary.Pepsinogen and gastrin-17 are biomarkers of gastric mucosa and gastric antra.The serological testing for the stomach-specific biomarkers offers the possibility to know preneoplastic gastric mucosal conditions.

Objective To find out the risk factors of early pulmonary infections after renal transplantatioa Methods The data were collected from 96 patients receiving renal transplantation between Oct. 2006 and Oct 2010, including 48 cases of early lung infection after renal transplantation as infection group, and 48 patients receiving immunosuppressive regimen at the same period as-control group. Taking the factors of lung infecition as variables, t test or chi-square test was used in univariate analyses whereas logistic regression was used in multivariate analyses.
