Objective To investigate the effect of a modified cuff insertion technique named “portal vein branch-sling” (PBS) method for portal vein (PV) anastomoses in rat liver transplantation.MethodsA total of 60 cases of orthotopic liver transplantation (OLT) using 2-cuff technique in rats were performed in our transplantation center.The PBS technique and conventional methods were used respectively in study and control groups.Time for PV anastomoses,anhepatic phase (AP) and surgery of recipients,successful rate for PV cuff insertion and operation were statistically compared between the different groups.Results35 cases of OLT using PBS technique in rats were assessed.The successful rate of PV cuff insertion was 94.3％,and the time of PV anastomoses using the modified PBS cuff insertion technique was only 1.9 ± 0.7min.The successful rate of operation was 80％with a 21.8±2.2min AP.The study group showed significant differences (P＜0.05) compared with conventional group.The survival rate in the first week was 85.8％ with no statistical difference (P＞0.05).ConclusionsThe modified PBS cuff insertion technique for PV anastomoses of OLT has advantages in speed,safety and stabilization,and should be considered as one of the best available PV anastomosis technique for OLT in rats.

Objective: To observe the effects of electroacupuncture (EA) at Tianshu (ST25) on pro- and anti-inflammatory cytokines in sodium taurocholate-induced severe acute pancreatitis (SAP) in rats. Methods: Sixty-six male Sprague-Dawley rats were randomly divided into three groups: sham-operation group, SAP group and EA group. An SAP model was established by injecting 3.5% sodium taurocholate at a dose of 1 mL/kg through puncturing the pancreatic duct. In the EA group, EA at ST25 was performed with sparse-dense wave (2/100 Hz, 2 mA for 30 min) immediately after sodium taurocholate injection and 30 min before sacrifice. Rats were sacrificed at 3 (n=7), 6 (n=7) and 12 h (n=8) after operation. Levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and IL-10 in serum were estimated by enzyme-linked immunosorbent assay. Pathological changes of pancreatic tissues were examined by hematoxylin and eosin staining and observed under a microscope and also scored. Results: The levels of serum TNF-α and IL-6 of SAP rats were significantly higher than those of sham-operation rats at 3, 6 and 12 h. The level of IL-10 in serum of SAP rats was significantly higher than that of sham-operation rats at 3 and 6 h (P<0.05). EA at ST25 down-regulated the levels of TNF-α and IL-6 in serum and up-regulated the level of IL-10 and the ratio of IL-10/TNF-α, also attenuated the morphological damages at 6 and 12 h (P<0.05) in rats with SAP. The pathological scores of pancreatic tissues in the EA group were significantly less than those in the SAP group at 6 and 12 h (P<0.05). Conclusion: EA at ST25 may have a therapeutic effect on rats with SAP by down-regulating the levels of TNF-α and IL-6 and up-regulating the level of IL-10 to re-establish the balance of pro- and anti-inflammatory cytokines, and to ameliorate the inflammatory response of SAP.

Objective To investigate the characteristics of the diagnosis and treatment center for Ebola observing ward and reduce infection risk according to allocation scheduling method of nursing staff. To provide reference for other similar tasks. Methods We used the method of grouping fixed group scheduling method and fixed working hours to identify and refine the content of nursing work. Results A total of 65 cases of suspected Ebola including 5 cases diagnosed as EVD patients were cured. No case of infection occurred in nursing staff. Conclusions During the infectious disease nursing work, reasonable personnel allocation and scheduling method can make the nursing staff work with full energy and strength and ensure the realization ofzero infectiontargets.

Objective To investigate the role of cytokines combined with CLIF Consortium organ failure score (CLIF-COFs) in determining the prognosis of liver transplant in hepatitis B-related acute-on-chronic liver failure (HB-ACLF) patients.Methods Thirty-seven cases of HB-ACLF patients undergoing liver transplantation were divided into HB-ACLF patients with complications group (n =15) and those without complications (n =22).Plasma were prospectively collected immediately before LT and on the 1st,3rd,5th,7th day after LT in HB-ACLF patients.The serum levels of twenty-seven cytokines were determined by 200 LUMINEX liquid chip technology.Cytokines and CLIF-COFs were analyzed with logistic regression and the receiver operating characteristic to confirm the correlation with the total complications post-LT.Results The serum levels of post-transplant G-CSF and MCP-1 in HB-ACLF patients with complications were higher than those of without complications (P ＜ 0.05).The COX analysis indicated that MCP-1 and CLIF-COFs were predictors of post-LT complications [A UC:0.821,95％ CI:0.668-0.974;AUC:0.738,95％ CI:0.578-0.898].The discriminatory power of MCP-combined with CLIF-COFs [AUC:0.839,95％ CI:0.703-0.975] was better than that of either.Conclusions MCP-1 combined with CLIF organ failure score can better predict the short-term outcomes of liver transplantation in HB-ACLF patients.

Objective To describe the CT features of giant lymph node hyperplasia in abdomen.Methods A retrospective study of CT features of giant lymph node hyperplasia in abdomen confirmed by surgery or biopsy pathology was performed.CT findings of all lesions were assessed by two radiologists including size,location,pattern of enhancement and density characteristics.Results 1 2 patients with giant lymph node hyperplasia in abdomen were confirmed including 7 women and 5 men with age range from 11 to 75 years (median age 3 9 years).All patients underwent pre-and post-contrast enhanced CT.CT showed a single mass in 9 patients lo-cated at retroperitoneum in 5,porta hepatic in 2,and mesentery in 2.Multiple masses were located at chest,abdomen and neck in 3.The lesions ranged in size from 1.2 to 11.9 cm in maximum diameter with an average size of 3.7cm.CT showed all lesions with well-defined margin and regular shape.The lesions less than 5 cm in diameter usually showed homogeneous enhancement,and how-ever those more than 5 cm showed heterogeneous enhancement.The calcification was seen in two patients.Conclusion CT features of giant lymph node hyperplasia in abdomen are characteristic.

The neuropeptide orexins, including orexin A and orexin B, are located exclusively in hypothalamus OX1R and OX2R are receptors of orexin. OX1R is selective to orexin A while OX2R is not. The distributions of orexin neurons in human brain are the same as those of rats. Orexin was closely related with sleep and awakening behavior besides regulating the feeding behavior. Orexin-containing terminals are also found in areas modulating sleep and awakening such as the locus ceruleus, tuberomammillary nucleus, dorsal raphe, and the basal forebrain. In those areas, there are also lots of OX1R and OX2R and their precursors. Orexin neurons are extremely active during rapid wave sleep and awakening. If hypothalamus in some areas is destroyed and orexin neurons are reduced, sleep-awakening dysfunction will appear (for instance: narcolepsy).

Using Vibrio fluvialis Ⅱ as host bacteria, 19 bacteriophages have been isolated from the 76 samples which were collected from Haliotis discus hannai ～growing seawater in Dalian marine culture company Dalian, liaoning province from May in 1996 to August I 1997. Ultrastructure of 19 bacteriophages were observed with electron to Bradley the results showed that of these bacteriophages belonged to Bradley A type, they have hexagonal heads of bacteriophages were identified with VP1,VP2,VP4,VP8 as representatives respectively. The phages remain stable at pH6. 0～10. 0, moreover VP2,VP4 and VP8 are rather stable at basic pHs. Although the characterization of heat inactivation course of VP4 is different from others, four phages are sensitive to heat and inactivated at 80℃ in 5 minutes. One step growth experiment showed that the eclipse period of VP1,VP2,VP4,VP8 are sensitive to heat and the eclipse period of VP1, VP2, VP4, VP8 are 42, 30, 46, 28 minutes. In this experiment we have isolated at least four different types phages, it suggest that in fact there is a population of phages in the seawater environment. The result of this study provided a way to find the potential value of phages as an indicator of pathogenic microorganisms Vibrio fluvilis Ⅱ in marine environment.
