ABSTRACT

Objective:To investigate the techniques used in blood flow control of Kimura laparoscopic spleen-preserving pancreatectomy (LSPDP).Methods:Forty·five patients with benign or low-grade malignant pancreatic diseases undergoing LSPDP at Huzhou Central Hospital from May 2014 to Oct 2021 were analyzed retrospectively. Patients were divided into splenic vascular flow control group ( n=22) and routine management group ( n=23). Results:There was no significant difference in gender, age, BMI, accompanying symptoms, hypertension, diabetes, lesion size and pathological diagnosis between the two groups (all P>0.05). A higher overall spleen preservation rate (90.9% vs. 52.2%, χ2=8.213, P=0.004), lower incidence of morbidity with Clavien grade ≥ Ⅱ (22.7% vs. 73.9%, χ2=9.911, P=0.002) and shorter postoperative hospital stay [(9.6±4.5) d vs. (14.3±6.6) d, t=2.447, P=0.008] were achieved in the vascular flow control group compared with those in the routine group. Conclusion:Splenic vascular flow control techniques improve the success rate of spleen preservation in laparoscopic distal pancreatectomy, reduce the postoperative complications and shorten the postoperative hospital stay.

ABSTRACT

The recombinant adenoviruses expressing miR-22 (Ad-miR-22) was constructed and the effect of Ad-miR-22 on insulin signal pathway and glucose uptake in HepG2 cells was analyzed. MiR-22 gene was amplified by PCR from human hepatocytes and cloned into the pAdTrack-CMV vector to generate the shuttle plasmid pAdT-22. The positive colonies were confirmed by PCR and sequencing. The resultant shuttle plasmid was linearized with Pme I, followed by co-transformation into competent BJ5183 cells containing an adenoviral backbone plasmid (pAdEasy-1) to create the recombinant plasmid pAd-miR-22. After digested with Pac I, the linearized pAd-miR-22 was transfected into 293A packaging cell line to generate recombinant adenoviruses Ad-miR-22. HepG2 cells were infected with Ad-miR-22 or control Ad-GFP (adenoviruses expressing green fluorescent protein), and then the miR-22 expression levels were analyzed by qPCR. The result shows that adenovirus-mediated overexpression of miR-22 significantly decreased insulin-induced glucose uptake in HepG2 cells. Moreover, overexpression of miR-22 markedly decreased insulin-induced phosphorylation of GSK-3β. miR-22 also increased the mRNA levels of gluconeogenic genes in HepG2 cells. Furthermore, Western blotting results indicate that the protein expression of SIRT1 decreased in Ad-miR-22 infected HepG2 cells as compared with Ad-GFP infected HepG2 cells. In summary, overexpressing of miR-22 significantly increased gluconeogenesis while decreased glucose uptake in HepG2 cells. The effect of miR-22 on glucose metabolism may be mediated by SIRT1.

ABSTRACT

Objective To investigate the preventive effects of anti-viral therapy in combination with transcatheter arteria chemoembolization (TACE) on recurrence of HBV-related hepatocellular carcinoma (HCC) after operation. Methods According to selection standards, 49 patients treated in this hospital from January 2003 to June 2009 were enrolled in this study and divided into a control group and combined group.The cumulative tumor-free survival rate, cumulative survival rate, the 1-, 2- and 3-year recurrence rates and cumulative recurrence rates were determined in all the patients and compared between the 2 groups. Results The cumulative tumor-free survival rate and cumulative survival rate were significantly higher in the combined group than in the control group (P=0. 019, 0. 008). The 1-, 2-, and 3-recurrence rates were 24% vs. 38.9%, 28% vs. 33.3%, and 28% vs. 22.2% in the combined group and control group, respectively. The 1-, 2-, and 3-year cumulative recurrence rates were 24% vs. 38. 9%, 52% vs. 72. 2%, and 80% vs.94. 4% in the combined group and control group, respectively. Conclusion Anti-viral therapy in combination with TACE can exert significant preventive effects on recurrence of HBV-related HCC after operation.
