Objective To investigate the selection and efficacy of operative medality for pancreatic transec-tion with major duct injury. Methods The clinical data were retrospectively analyzed in 21 patients with pancreatic disruption. They were treated in our hospital from Jan. 1995 to Feb. 2009. There were 14 males and 7 females in these cases with a mean age of 26 years (range 9-53 years). The trauma causes of them were blunt injuries in 13 and patent injuries in 8 cases. The injury grade (according to American Association for the Surgery of Trauma) distribution for these patients was grade Ⅲin 8 cases, grade Ⅳ in 8 cases, and grade V in 3. The early emergency operation was performed in eighteen within 12 hours, and delayed opera-tion was in three cases. Of these operative medalities, Roux-en-Y distal panereatojejunostomy was in 10 ca-ses, pancreatoduodenectomy was in 3, modified duodenal diverticulizatian was in 2, distal pancreatectomy was in 3, tube installing in major duct and external drainage, and suture of pancreatic section was in 2, su-ture of two broken sides in 1 (Roux-en-Y distal pancreatojejunostomy in second time). Results Twenty patients were cured, and one was died after a procedure of pancreatoduodenectomy. The postoperative pan-creatic fistula happened in 3 cases and recovered well with conservative line of management. Conclusions For improving the outcome of pancreatic transection, the earlier exploratory laparotomy and carrying out concept of "Damage Control Surgery" are critical. The individual operative modality based on the grade should be a-dopted in the surgical procedure.

BACKGROUND:The interaction of neural network and motor function in post-stroke brain tissue remains unclear.
OBJECTIVE:To observe neural network impairment fol owing subacute stroke by using diffusion tensor imaging, and to investigate the relationship with neurological defects and motor dysfunction.
METHODS:A total of 19 patients after subactue stroke and 20 healthy adults were examined with diffusion tensor imaging. The fol owing parameters were compared:fractional anisotropy, apparent diffusion coefficient, asymmetry indices of fractional anisotropy and apparent diffusion coefficient. The neurological defect and motor function were evaluated with the corresponding scales. The 10-meter walking speed was measured. The correlation of diffusion tensor imaging parameters with the scale scores and 10-meter walking speed was analyzed.
RESULTS AND CONCLUSION:The stroke group exhibited reduced fractional anisotropy value asymmetry and fractional anisotropy value in bilateral posterior limbs of the internal capsule. Apparent diffusion coefficient value asymmetry and apparent diffusion coefficient value in the posterior limb of the internal capsule were lower than control unaffected side (P<0.05). Apparent diffusion coefficient value and apparent diffusion coefficient value asymmetry in posterior limb of the internal capsule showed a strong negative correlation with Fugl-Meyer assessment scores of the lower extremities (P<0.05). Diffusion tensor imaging parameters is closely linked with motor dysfunction of the lower extremities in subacute stroke patients. Local stroke lesion-caused neurological defect is the leading cause of motor dysfunction of the lower extremities.

Objective To study the value of CT perfusion imaging(CTPI)on brain hemodynamic of the aged with cerebral infarction. Methods The 48 patients who were doubted with cerebral infarction underwent 16-slice CT plain scanning and CTPI within 24 hours of onset. The cerebral blood flow(CBF), mean transit time(MTT)and time to peak(TTP)of contrast-medium in region of interest(FOV)were used as brain hemodynamic parameters in comparation with contralateral regions. All cases were followed up with MRI after 3-10 days. Results Ischemia lesion was found on CT plain scanning in 40.9% of patients, while 93.2% of patients showed abnormal perfusion on CTPI. The sensibility of CTPI in identifying ischemia area was 93.2%, and the specificity was 100%. CBF in research area was significantly reduced, MTT and TTP were remarkably increased in contrast to counterparts(P<0.01). Conclusions CT perfusion imaging can sensitively reveal the hemodynamic condition of cerebral ischemia, which could provide the important information for early diagnosis and treatment of the elderly with brain infarction.

LncRNAH19 has been implicated as having both oncogenic and tumor suppression properties in cancer. LncRNAH19 transcripts also serve as a precursor for miR-675. However, it is unknown whether LncRNAH19 and miR-675 are involved in the migration and invasion of hepatocellular carcinoma (HCC) cells. The purpose of this study was to investigate the effect and mechanism of LncRNAH19 and miR-675 on migration and invasion of HCC cells. The migration and invasion of HCC cells were measured by Transwell migration and invasion assays after transfection of HCC cells with miR-675 inhibitors and LncRNAH19siRNA. The levels of LncRNAH19 and miR-675 were detected by quantitative reverse transcriptase real-time polymerase chain reaction (qRT-PCR), and the protein expression of AKT, GSK-3β and Cdc25A by Western blotting analysis. The expression levels of LncRNAH19 and miR-675 were higher in MHCC-97H cells than in L02, Huh-7 and HepG2 cells. Transwell migration assay revealed that the miR-675 inhibitor and LncRNAH19siRNA could significantly increase the migration of HCC cells (P<0.01) as compared with the control group. Transwell invasion assay demonstrated that the miR-675 inhibitor and LncRNAH19siRNA could significantly increase the invasion of HCC cells (P<0.01) as compared with the control group. Western blotting analysis showed that the expression levels of AKT and Cdc25A were significantly increased (P<0.05), and the expression level of GSK-3β was significantly decreased (P<0.05) after treatment with miR-675 inhibitors and LncRNAH19siRNA as compared with the control group. These findings suggested that inhibition of LncRNAH19 and miR-675 expression can promote migration and invasion of HCC cells via AKT/GSK-3β/Cdc25A signaling pathway.

Objective To investigate the correlation of motor function and emotion, cognition in patients after stroke. Methods 15 sub-acute stroke patients were included. They were assessed with Fugl-Meyer Assessment (FMA)、10 m walking speed, Hamilton Rating Scale for Depression (HAMD), Hamilton Rating Scale for Anxiety (HAMA), Mini-Mental State Examination (MMSE), modified Barthel Index (MBI) and SF-36. Fractional anisotropy (FA) values, apparent diffusion coefficient (ADC), and asymmetry indices of ADC and FA were obtained from diffusion tensor imaging. The correlation among them were analyzed. Results There was no correlation between the scores of FMA, 10 m walking speed and HAMD, HAMA, MMSE (P>0.05). The scores of HAMD, HAMA and MMSE correlated with emotional function of SF-36 (P<0.05). The HAMA score negatively correlated with body pain of SF-36. The FA value of the posterior limb of the internal capsule were negatively correlated with HAMD (P<0.05). Conclusion Neural network defect can cause emotion changes in stroke patients, but the motor function was not correlated with the emotion. Emotion and cognition may affect quality of life in these patients.

Objective To explore for the methede and effect of endoscopic treatment on biliary leakage and biliary duct damage. Methods All patients with biliary damage such as biliary leakage and biliary duct stricture were treated by endoscopic sphincoterotomy and endoscopic nasobiliary drainage (ENBD) during abdominal cavity drainage ENBD was removd when biliary leakage healed and abdominal cavity drainage ceased for 1~2 weeks were confirmed. Plastic stents were implanted to distend the biliary duct stricture for 2-3 months. Results Twenty-six patients with biliary leakage were cured 3-4 weeks after ENBD. Fourteen out of 17 patients implanted with plastic stent were recovered uneventfully after stent removed, and 4 patients also recovered after installation of double-stents for 3 months, while another case with calculus and stricture of left hepatic duct in spite of implantation of simple-stent suffered repeatedly from biliary tract infection and one case developed hepatic abscess after repeatedly infection for one year before he had the hepatic lobectomy. Conclution Endoscopic therapy is the first choice in treating biliary leakage or secondary duct stricture.

Objective To study the changes of PI3K/Akt/GSK3β signaling pathway during resuscitation with neck cooling in order to explore the relationship between the protective effect of neck cooling and the phosphorylation of PI3K/Akt and GSK3β.Methods Thirty rabbits were randomly(random number) divided into five groups, and models of cadiac arrest were induced by ventricular fibrillation(VF, the positive electrode in the right ventricle and negative pole on the apex of heart) for 4 min.In sham group,a electrode was placed into right ventricle without electric current conducted, and CA was not induced.The rabbits were sacrificed and specimens were taken at 24 hours after modeling.In normothermia treat group(NT group),resuscitation was carried out to restoration of spontaneous circulation(ROSC),and the rabbits were sacrificed and specimens were taken at 24 hours after modeling.In intra-arrest therapeutic hypothermia group (IATH group), rapid neck cooling was initiated at the same time with CPR,and the target brain temperature was set at 34 ℃ maintained for 4 hours after ROSC.Rabbits were sacrificed and specimens were taken at 24 hours after modeling.In recovery period cooling + LY294002 group(PATH+LY294002 group), LY294002 was injected intra-ventricularly at 20 minutes before resuscitation.Rapid neck cooling was started at the same time with CPR,and the target brain temperature was set at 34 ℃ maintained for 4 hours after ROSC.The rabbits were sacrificed and specimens were taken at 24 hours after modeling.In post-arrest therapeutic hypothermia group (PATH group), rapid neck cooling was begun after CPR for 1 hour,and the target brain temperature was set at 34 ℃ maintained for 4 hours after ROSC.The rabbits were sacrificed and specimens were taken at 24 hours after modeling.Animals were sacrificed by using overdose anesthetic drug.Western blot was used to detect the level of Akt p-Akt GSK-3β p-GSK-3β (ser9) protein, and TUNEL was used to observe apoptosis of tissues in each group.Multiple comparisons were performed with one-way analysis of variance (ANOVA).Results Compared with Sham group, Akt (Thr-308) phosphorylation (P-AKT) and P-GSK-3β levels in the brain neuron cytoplasm in 24 hours after CPR resuscitation in NT group was significantly reduced, and showed a gradual reduction trend (P<0.05);the P-AKT and P-GSK-3β levels in the brain neuron cytoplasm in 24 hours after CPR resuscitation in IATH group were significantly enhanced compared with NT group (P<0.05);the levels of these two kinds of protein at one hour after resuscitation in PATH group were significantly enhanced compared with NT group (P<0.05), but lower in IATH group.Intra-ventricularly injection of LY294002 made the effect of hypothermia lost, indicating that LY294002 inhibited the phosphorylation of Akt.Apoptosis cells were significantly reduced in IATH group and normothermia theatment group compared with PATH group and LY294002 group(P<0.05).Conclusions Neck cooling can reduce apoptosis in rabbit brain cells after recovery, and the protective effect on brain is best in intra-arrest therapeutic hypothermia group.LY294002 specifically block the PI3K/Akt pathway, and the protective effect of cooling on the brain can be abolished,indicating hypothermia protects the neurological function via activation of PI3K/Akt pathway.Neck cooling protects the neurological function by activating PI3K/Akt/GSK-3β, promoting the Akt activation, and increasing the expression of P-GSK3β.Specific Akt inhibitor LY294002 inhibits Akt phosphorylation of brain tissue recovery and further inhibit the phosphorylation of GSK-3β, thus abolishing protective effect of cooling on neurological function.
