Objective : To investigate the dynamic changes of the expression of GLUT1 mRNA and GLUT4 mRNA in rats myocardium with transient ischemia and reperfusion, and the relationship between the dynamic changes and the time during reperfusion. Methods : In rats, the left anterior descending coronary artery was occluded for 20 min followed by reperfusion for 4 hours, 1, 3 or 7 days as ischemia reperfusion model. The relative content of GLUT1 mRNA and GLUT4 mRNA in myocardium was detected by RT-PCR and gel electrophoresis imaging. Results: During myocardial post-ischemia and reperfusion, the levels of GLUT1 mRNA got up to the peak at 4th hour[ (0.666?0. 003 ) vs (0. 509?0.002) controls , P 0.05). Conclusion; Transient ischemia and reperfusion induce the expression of glucose transporters GLUT1 and GLUT4 genes in rat myocardi- um, which contribute to promote glucose utilization during ischemia, protect ischemic myocardium and improve functional recovery on reperfusion.

BACKGROUND: Fluorescence molecular tomography (FMT) has become a fast developing molecular imaging technique. Noise is a challenge for FMT, and the influence of noise on molecular imaging remains unclear, OBJECTIVE: To investigate the influence of noise on imaging reconstruction based on the adaptive-mesh-based algorithm using an analytical solution.METHODS: In this paper, the influence of noise on FMT was studied based on the adaptive-mesh-based algorithm using an analytical solution.RESULTS AND CONCLUSION: By adding noise to the simulated data, the reconstruction results with different signal-to-noise ratio are obtained and discussed. The experiment results show that the adaptive-mesh-based algorithm is robust in the existence of noise.

Objective To study the recent effect of ovary dislocation during the operation of cervical squa- mous carcinoma with stageⅠon ovary function.Methods 12 cases with cervical squamous carcinoma of stageⅠwere treated with surgery.During the operation bilateral ovaries with blood vessels were dislocated the abdominal cavity over the umbilical line through postperitoneum and fixed on the postperitoneum.12 cases were hysterec- tomized simply as the control.The change of ovary function was observed in one year after the operation.Results The levels of FSH and E_2 were decreased in the dislocating group(P

Objective To summarize the nursing experience of patients with artificial airway in intensive care unit(ICU).Methods 126 patients with artificial airway in ICU were collected,by using the digital table method,the patients were randomly divided into observation group(69 cases)and control group(57 cases).The control group was only given traditional nursing method,the observation group was given cluster nursing.The hospital time,indwelling time,unplanned extubation,ventilator associated pneumonia and the patients' satisfaction were assessed.Results After treatment,the hospital time,indwelling time,unplanned extubation,ventilator associated pneumonia of the observation group were(7.47±1.35)days,(4.16±0.89)days,four cases(5.80%),six cases(8.70%),respectively,which of the control group were(14.06±2.39)days,(9.64±2.34)days,nine cases(15.79%),fifteen cases(26.32%),respectivelywhich was lower than those of the control group [(14.06±2.39)days,(9.64±2.34)days,nine cases(15.79%),fifteen cases(26.32%)].The hospital time,indwelling time,the incidence rate of unplanned extubation and ventilator associated pneumonia of the observation group were shorter or lower than those of the control group(t=4.785,5.312,x2=4.991,5.471,all P<0.05).The satisfaction of the observation group was higher than that of the control group,the difference between the two groups was statistically significant(P<0.05).Conclusion Cluster nursing can significantly reduce the length of stay in hospital,extubation time,and reduce the incidence of accidental extubation and ventilator associated pneumonia.At the same time,psychological nursing can improve the satisfaction of patients and promote the recovery of patients.

The"Experiencing teaching"is a students-centered and task-based teaching approach,from which students can apply what they learn to practice through their own experiences in classes.Using experiencing teaching in medical psychology,we get good teaching effects.

Objective To compare wedge biopsy and disposable automatic biopsy gun biopsy for the diagnosis of pancreatic cancer. Methods The clinical data of 217 patients with unresectable pancreatic cancer undergoing palliative operation and biopsy were retrospectively analyzed in our hospital from March 25,2006 to March 25,2011.Group A(wedge biopsy) consisted of 120 cases and B( disposable automated biopsy gun biopsy) of 97 cases.The success rate of biopsy,the positive rate of biopsy,the accuracy of diagnosis and the incidence of postoperative complications were calculated. Results The success rate,positive rate,diagnostic accuracy and the incidence of postoperative hemorrhage of group A and B were 100％,97.5％,97.5％,1.7％ and 100％,99％,99％,1.0％,respectively ( all P ＞ 0.05 ).The incidence of postoperative pancreatic leakage in group A and B were 11.7％ and 2.1％ (P =0.007 ).Conclusions Intra-operative biopsy for the diagnosis of pancreatic cancer using disposable automated biopsy gun biopsy has significantly decreased the incidence of post-biopsy pancreatic leakage as compared with wedge biopsy.

ObjectiveTo evaluate the effect on organ function by early peritoneal puncture and catheter drainage for intra-abdominal hypertension during the course of severe acute pancreatitis (SAP).MethodsA retrospective study was conducted on 405 patients of severe acute pancreatitis with IAH at Department of Pancreatic Surgery,Wuhan Union Hospital from January 2001 to September 2010.In the early course of SAP,137 cases did not receive peritoneal puncture and drainage decompression,268 cases were treated with peritoneal puncture and drainage decompression.ResultsThe differences of the scores of UBP and APACHE Ⅱ were statistically significant between the puncture group and the non-puncture group (P ＜ 0.05).The occurrence of ARDS,ARF and MODS in the group of puncture were significantly lower than those of the non-puncture group (14％ vs.27％,21％ vs.32％,9％ vs.14％,respectively,all P ＜0.05 ).At the same time,the differences between rate of early laparotomy and rate of early mortality in the two groups were statistically significant (4％ vs.12％,3％ vs.6％,respectively,all P ＜0.05).However,there was no significant difference in the occurrence time of negative balance in the two groups (5.9 ±2.9 vs.5.9 ± 2.4,P ＞ 0.05 ).ConclusionsEarly abdominal puncture and drainage reduce the abdominal pressure of patients with SAP and IAH.It also reduces the occurrence of organ failure,the rate of early laparotomy and the rate of early mortality in SAP patients.

Objective To investigate the effect of Ulinastatin preconditioning on hyperthermia induced rat skeletal muscle injury and the possible mechanism. Methods Cultured skeletal muscle cells were divided into 7 groups: control group (Group C), as normal culture; hyperthermia treated group (Group H), in which cells were exposed to 42℃for 2 hours then transfered to normal culture; ulinastatin preconditioned group (Group U), which were only preconditioned 1 hour by the final concentration of ulinastatin at 1 250 U/mL; and four different concentration of ulinastatin preconditioned+hyperthermia treated groups (Group Ⅰ, Ⅱ, Ⅲ, Ⅳ), in which cells were preconditioned 1 hour by the final concentration of ulinastatin at 312 , 625, 1250, 2 500 U/mL, respectively. And then, all the four groups were exposed to 42℃for 2 hours. MTT assay and LDH leakage were performed to study the cytotoxicity. Superoxide dismutase (SOD) activity and malondialdehyde (MDA) formation were measured to reflect the activity of antioxidase. Results Compared with Group H, MTT value in ulinastatin preconditioned group in GroupⅠ, Ⅱ,Ⅲ, Ⅳsignificantly increased (P<0.05) LDH leakage significantly decreased (P<0.05). And the activity of SOD in cultured cells significantly increased (P < 0.05), the content of cellular MDA was also significantly decreased (P<0.05). But there were no significant difference among Group Ⅰ, Ⅱ,Ⅲ,Ⅳ(P>0.05). Conclusion Ulinastatin preconditioning may have protective effect against hyperthermia induced skeletal muscle injury and it may be related to its ability of inhibiting radical production and promoting radical scavenging.

Objective To investigate in vitro anti-hydatid efficacy on Echinococcus granulosus protoscolex(EgPSC) by using albendazole sulfoxide(ASOX) and its two enantiomeric antipodes, L-ASOX and D-ASOX.Methods Eg protoscoleces were divided into eight groups and cultured in the DMEM culture media under two concentrations(50 ?g/ml and 100 ?g/ml) of ASOX, L-ASOX and D-ASOX respectively.The appropriate controls included(i) a culture containing an equal amount of DMSO and(ii) a culture medium alone.The mortality of EgPSC in each group was daily counted until 100% EgPSC death in some groups.Results Significant difference of EgPSC mortality was found among the three drugs with various concentrations compared to control group(P0.05), but between ASOX group and L-ASOX group(P
