Objective To evaluate ipsilateral hepatic blood flow exclusion in combination with liver hanging manoeuvre for hepatectomy. Methods From Jul 2007 to Feb 2008, 14 cases underwent hemihepatectomy under ipsilateral hepatic blood inflow and draining hepatic vein exclusion in combination with liver hanging manoeuvre for liver malignancier or ligating ligating vessels, portal vein branch and major hepatic vein to set up a tunnel at the interior vena cava. Results Small laceration on fight hepatic vein was encountered in 2 cases during the operation and managed by suturing. There was no intraoperative injury on inferior vena cava or short hepatic veins. Blood loss ranged from 100 ml to 600 ml with a mean of 280 ml. Postoperative pleural effusion was cured conservatively in 3 cases and paracentes was needed in one case. There was no severe postoperative hepatorenal dysfunction, biliary fistula, infection or other major complications. The operative mortality was nil. Conclusion For regular major hepatectomy, ipsilateral hepatic blood flow exclusion plus liver hanging manoeuvre has the advantage of less blood loss and protecting contralateral hemiliver from reporfusion injuries.

[Objective]To explore the effect and the possible mechanism of the proteasome inhibitor MG132 on acute T lympho?blastic leukemia cells.[Methods]The influence of different concentrations of MG132 in the viability and proliferation of CCRF-CEM was measured by MTS. Apoptosis rates of CCRF-CEM treated by MG132 were determined by flow cytometry. After being exposed to MG132,the protein levels of FOXO3a in cytoplasm and nucleus were analyzed by Western blotting. qRT-PCR was applied to detect the mRNA of FOXO3a and Puma in cells treated by MG132. Then CCRF-CEM was stably transfected with antisense FOXO3a using Lentivirus infection. We further investigated the effects of MG132 in FOXO3a-shRNA cells and elucidated the mechanisms of FOXO3a and Puma.[Results]MG132 inhibits the proliferation of CCRF-CEM,but has no cytotoxicity in peripheral blood mononu?clear cells(PBMC). Cellular apoptosis was induced in cells treated with MG132. At mRNA level,MG132 had no influence on FOXO3a,but increased the expression of Puma. However,MG132 promoted the expression of both FOXO3a and Puma at protein level. Interestingly,the expression of FOXO3a increased very little in cytoplasm. In FOXO3a-shRNA cells the expression of FOXO3a and Puma decreased at protein level. FOXO3a's knockdown attenuated the proliferation inhibition mediated by MG132.[Conclusion]MG132 inhibits the proliferation and promotes to apoptosis of CCRF-CEM. One of the mechanism is that MG132 inhib? its the degradation of FOXO3a,and then activates FOXO3a/Puma pathway.

Objective To compare the short-term quality of life after total gastrectomy in patients with gastric cancer with three recontructive methods of stamoch storage function. Methods Totally 62 cases underwent jejunal interposition afar total gastrectomy from March 2000 to December 2007. Patients were divided into three groups according to the procedures: functional jejunal interposition (FJI-type) group ( n = 23 ), modified jejunal interposition ( Ⅲ -type) group ( n = 20), and P-type jejunal interposition (P-type) group (n = 19). In each group,the patients' general conditions, the nutritional status at month 3 and 12, and gastrointestinal symptoms were evaluated. Results The durations of procedures were significantly different among three groups (P <0. 01 ). The intraoperative bleeding volume, postoperative complications, and food intake of each meal at month 3 were not significantly different ( P > 0. 05 ). Compared with the data at month 3, the levels of hemoglobin and serum calcium at month 12 were significantly higher in all three groups (P < 0. 01 ). Compared to the level at month 3, the level of serum albumin at month 12 significantly increased in FJI-type group (P < 0. 05 ) but showed not significant difference in Ⅲ-type group and P-type group ( P > 0. 05 ). The incidence of reflux esophagitis in three groups and the comparative parameters among the three groups at month 12 were not significantly different ( P > 0. 05 ). Conclusions The jejunal interpositions after total gastrectomy will not increase the complexity and risk of the surgical procedure. In fact, they can reduce the reflux esophagitis and improve quality of life by keeping the storage function and restoring food passage through the duodenum. FJI-type is simpler than the other two types, and P-type is preferred for operations that need to open the pectoral cavity.

Objective To explore the mechanism of Zibu Piyin Recipe (ZBPYR) on spleen yin deficiency diabetes-associated cognitive disorder (DACD). Methods The rats were randomly divided into control group, diabetes mellitus (DM) group, spleen yin deficiency group, spleen yin deficiency DM group and spleen yin deficiency DM+ZBPYR group (treatment group). Type 2 DM models were established by high-fat food feeding and low dose STZ intraperitoneal injection for 4 weeks. Then the classical compound method was used to construct spleen yin deficiency rat models by improper diet, over exertion and yin fluids exhaustion. The treatment group was given ZBPYR by gavage for 15 days, and the other groups were given the same amount of normal saline. Then cerebral cortex, hippocampus, stomach and liver were obtained and the changes of protein expression of PDHE1α in them were observed by Western Blot. Results The protein expression of PDHE1αin cortex of DM group and spleen yin deficiency DM group were lower than control group (P<0.05). PDHE1α expression of treatment group in cortex and stomach increased more significantly than spleen yin deficiency DM group (P<0.05). The expression of PDHE1α protein showed no significant difference among all groups in hippocampus and liver. Conclusion ZBPYR improved spleen yin deficiency DACD by regulating PDHE1αin cortex and stomach.

This study was aimed to observe changes of key molecular in insulin signaling pathway in the hypothala-mus of rats to explore the mechanism of spleen yin deficiency diabetes-associated cognitive decline (DACD) and Zibu Piyin Recipe (ZBPYR) in order to provide new ideas and new clues for treatment of DACD. Rats were randomly divided into five groups, which were the control (Cont) group, diabetes (DM) group, spleen yin deficiency (pi) group, spleen yin deficiency diabetes (piDM) group and the ZBPYR group. Insulin receptor substrate 1 (IRS-1) serine phos-phorylation levels and protein kinase B (PKB/Akt) serine phosphorylation levels which were involved in the insulin signaling were observed by western blotting in the hypothalamus to determine whether there were insulin signaling obstacles in the hypothalamus of rats. The results showed that the expression of p-IRS-1ser in the DM group, pi group and piDM group was increased compared with the Cont group (P< 0.05); while the p-Akt expression of the DM group and piDM group was decreased (P< 0.05). The expression of p-IRS-1ser in the ZBPYR group decreased compared with the DM group and piDM group (P< 0.05); while the level of p-Akt increased compared with the DM group and piDM group (P < 0.05). It was concluded that insulin signaling was not transduced normally in the hy-pothalamus of the DM group, pi group and piDM group. Insulin resistance may occur in the hypothalamus. And ZBPYR can correct insulin signaling transduction disorder.

This study was aimed to observe different forms of β-amyloid peptide (Aβ) and insulin degrading enzyme (IDE) in the hippocampus and cortex in order to further explore the role of Aβ and IDE on spleen yin deficiency di-abetes-associated cognitive decline (DACD), and the effect of Zi-Bu Pi-Y in method. The rats were randomly divided into five groups, which were the blank control (Cont) group, diabetes (DM) group, spleen yin deficiency (pi) group, spleen yin deficiency diabetes (piDM) group and Zi-Bu Pi-Y in recipe (ZBPYR) group. Soluble and insoluble Aβ in the hippocampus and cortex of rats were extracted by gradient centrifugation, and then measured by ELISA. The ex-pression of IDE was observed by western blot. The results showed that the content of soluble and insoluble Aβ1-42 in the hippocampus and cortex of the DM group and piDM group were higher than the Cont group. The soluble and in-soluble Aβ1-42 content in the hippocampus and cortex of the ZBPYR group were reduced compared with the DM group and the piDM group. The soluble Aβ1-40 in the cortex of the DM group, pi group and piDM group were in-creased compared with the Cont group (P < 0.05). The soluble Aβ1-40 content of the ZBPYR group was decreased compared with the DM group and the piDM group (P < 0.05). The expression of IDE protein was decreased in the hippocampus of the DM group and the piDM group compared with the Cont group (P< 0.05), and the IDE protein level in the hippocampus of the ZBPYR group was increased compared with the DM group and the piDM group (P<0.05). The expression of IDE protein in the cortex of the DM group, pi group and piDM group was lower than the Cont group (P< 0.05). The IDE protein level in the cortex of the ZBPYR group was reduced compared to the DM group (P< 0.05). It was concluded that the increased Aβ1-42 in brain may be a major pathological change of DACD and spleen yin deficiency DACD. The decreased IDE expression may be one of the reasons to induce increasing of Aβ1-42 level. The Zi-Bu Pi-Y in method may decrease the Aβ1-42 content by upregulating IDE protein expression.
