Objective To evaluate the effect of omega-3 polyunsaturaed fatty acid on liver function, donor's T lymphocytes and acute rejection following orthotopic liver transplantation in rats. Methods Orthotopie liver transplantation from BN (RT1 n) to Lewis was performed. Normal saline (NS, n = 6), parenteral nutrition (PN, n = 6) or parenteral nutrition and Omega-3 fatty acid (OM, n = 6) was given through internal jugular vein catheter respectively beginning the first day for consecutive 6 days. At 7thday, the liver function and pathological changes of the transplant liver were observed. The percentage of CD4+ , CD8+, CD4+ CD25+ and CD8+ CD28- T lymphocytes were analyzed by flow-cytometry. Results In OM group the CD4+, CD8+ , CD4+ CD25+ and CD8+ CD28- T lymphocytes significantly decreased, compared with NS (t = 4.28, P < 0.01 ; t = 2.63, P < 0.05 ; t = 2.59, P < 0.05 ; t = 8.86, P <0.01)or PN group(t =8.06, P<0.01; t =3.57, P<0.01; t =5.35, P<0.01; t =7.98, P<0.01). The ratio of CD4+ to CD8+ significantly decreased in OM group compared with NS group and PN group(t = 6.25, P<0.01; t=4.92, P<0.01). RAI (rejection activity index) in NS group, PN group and OM group was 7.17 +0.98, 6.17±0.75 and 4.33±0.52, respectively. The rejection grade in OM group was siguificanfly alleviated than that in NS group and PN group(t =6.25, P <0.01;t =4.92, P <0.01). Conclusion Omega-3 fatty acid inhibits T lymphocytes, especially help T lymphocytes, alleviates acute rejection. The suppressor T cell and the regulatory T cell were not responsible for the alleviation of the rejection.

Objective To compare different dose of remifentanil combined with propofol for painless abortion and approach to an appropriate dose of remifentanil.Methods Ninety pregnant women with ASA 1 were randomly divided into three groups(n=30)before administrating remifetanil,a bolus midazolam 1 mg was injected inminutes later.These two drugs did not stop administration until three minutes before the end of negative suction.MAP,HR,SpO2,BIS,RR,VT,PET CO2 were monitored.The onset,operation and recovery time,sedation score and adverse reaction were recorded.Results Sedation scores were significantly different between group A and C [(3.90±0.97)and(4.90±0.85),t=4.24,P＜0.01].Three cases in group A were found moving.MAP,HR,BIS decreased as compared witll baseline.HR reduced significantly in group C(P＜0.05,P＜0.01).Respiratory movement was lower and shallower.RR,VT decreased compared to preoperative one.PET C02 increased gradually (P＜0.05,P＜0.01).There were two cases of respiratory depressing in group A,four cases in group B and ten cases in group C(five cases apnea more than three minutes).All patients used oxygen mask to maintain SpO2＞95%.Incidence of adverse reactions such as chest titanic,nausea and vomiting,itching were of no difference among three groups(P＞0.05).All patients were satisfied with anesthesia.Conclusion The appropriate infusing dose of remifetory devices such as oxygen mask and monitoring life signs are very important to prevent respiratory depress and bradycardia during operation.

Objective To investigate the expression of doublecortin-like kinase 1 (DCLK1) in colorectal cancer and colorectal adenomas,and it's role in the development and progression of colorectal carcinoma,and explore the relationship of the DCLK1 expression and prognosis in colorectal cancer patients with diabetes medical history.Methods Expression of DCLK1 in 70 cases of colorectal cancers,70 cases of para-carcinoma tissues,and 35 cases of tubulovillous adenomas were detected by immunohistochemical method.Results (1) The DCLK1 high expression rate in colorectal cancers was 41.4％ (29/70),and 45.7％ (16/35) in tubular villous adenomas,both significantly higher than the para-carcinoma tissues (4.3％;3/70) (P ＜0.01).(2) DCLK1 high positive expression had statistical significance with pathological grading (P ＜ 0.01),infiltration depth (P ＜ 0.05),lymph node metastasis (P＜ 0.05),vascular invasion (P ＜0.05),and distant metastasis (P ＜0.01).(3) There was no obvious correlation between the Diabetes medical history,expression of DCLK1,and prognosis of patients.Conclusions DCLK1 has high positive expression in colorectal carcinomas,and may have certain significance for the early clinical diagnosis and prognostic judgment of colorectal cancers.The expression of DCLK1 and prognosis of colorectal cancers has no obvious correlation with diabetes medical history.

Objective To study the sedation and amnesia of midazolam in patients with different ages of lumbar epidural anesthesia . Methods From January to July 2015, 235 patients in the first affiliated of xian jiaotong unniversity,who were implemented abdominal surgery under combined spinal epidural anesthesia and American Society of anesthesiologists (ASA) grade was I-II , were divided into three groups:young group (n=70); middle-aged group (n =82); elderly group (n =83).Intraoperative continuous monitoring of respiratory and circulatory function index,and recorded MAP,SpO2, HR before and 5, 15, 30 min after injection.ResuIts MAP, HR and SpO2 of three groups were compared with the same time points pre-and post used of midazolam, there was no significant difference among indicators.; Compared with the same group at different time points, MAP(FYG =9.2547,FMG =12.8181,FOG =17.77)和 SpO2 (FYG =190.3835,FMG =196.2393,FOG =270.5609),there were significant difference.The difference was not statistically significant between HR group and the same group at different time points and forgetting degree and sedation score , but compared with OG,there were significant difference(P<0.05).The total number of adverse reactions in YG group and MG group was less than that of OG group(X2 =11.2516,X2 =10.4491, P<0.05).ConcIusion The effect of the same dose of midazolam on sedation and amnesia in patients with different ages of lumbar epidural anesthesia is different, and the degree of the effect of the elderly patients is significant,but will produce more adverse reactions.Therefore, in the combined spinal epidural anesthesia,it is necessary to consider the patient's individual differences, rational use of sedative and narcotic drugs.

OBJECTIVETo detect protein expression of ERK(1), ERK(2), JNK(1), p38 and MEK(1), MEK(2) in human hepatocellular carcinoma and adjacent non-neoplastic liver.

METHODSIn 16 surgically resected hepatocellular carcinoma and para-carcinoma tissues, Western blotting was used to detect expression of ERK(1), ERK(2), JNK(1), p38 and MEK(1), MEK(2).

RESULTSIn all cases, ERK(1), ERK(2), p38 expression in hepatocellular carcinoma was significantly higher than that in para-carcinoma: integral optic density (IOD) of ERK(1) was 300 +/- 98 in carcinoma and 98 +/- 48 in para-carcinoma tissues (t = 2.519, P < 0.01); IOD of ERK(2) was 587 +/- 83 in carcinoma and 232 +/- 96 in para-carcinoma tissues (t = 2.745, P < 0.01); IOD of p38 was 270 +/- 85 in carcinoma and 107 +/- 88 in para-carcinoma tissues (t = 2.491, P < 0.01). JNK(1) expression in hepatocellular carcinoma was significantly lower than that in para-carcinoma; IOD of JNK(1) was 111 +/- 93 in carcinoma and 292 +/- 109 in para-carcinoma tissues (t = 2.473, P < 0.01). Protein levels of MEK(1) and MEK(2) in carcinoma were significantly higher than in para-carcinoma. IOD of MEK(1) was 1 418 +/- 244 in carcinoma and 806 +/- 90 in para-carcinoma tissues (t = 2.546, P < 0.01). IOD of MEK(2) was 1 041 +/- 122 in carcinoma and 468 +/- 40 in para-carcinoma tissues (t = 2.861, P < 0.01).

CONCLUSIONSERK(1), ERK(2), MEK(1) and MEK(2) in the signal transduction pathway for cell proliferation are significantly overexpressed and the expression of JNK(1) is lower in hepatocellular carcinoma. Their unbalance is one of the important reasons for the over growth and infinite proliferation of the hepatocellular carcinoma cell. The p38 and JNK(1) may be activated by different pathway.

ObjectiveTo study the feasibility and technique in liver transplantation (LT) in an adult with situs inversus (SI) and reviewed the medical literature on this subject.MethodsA 45-year-old male with complete SI,suffered from progressive hepatic failure secondary to hepatolithiasis,obstructive jaundice,portal hypertension and liver cirrhosis.He underwent liver transplantation in July 2004.His anatomy was studied by preoperative CT scan and three-dimensional liver reconstruction imaging and angiography.LT was performed using the modified piggyback technique.The donor right liver was rotated 45 degree to the left,making the donor left liver pointing to the left paracolic sulcus and the donor right liver was in the recipient hepatic fossa.The donor suprahepatic vena cava was anastomosed end-to-side to the recipient vena cava,and the infrahepatic vena cava was closed by oversewing.ResultThe patient recovered uneventfully.His liver function was stable during a follow-up of 75 months.ConclusionLT in patients with SI is safe and feasible.Exact determination of the anatomy,comprehensive preoperative planning,and good technique in liver transplantation play important roles in LT for patients with SI.

Objective To evaluate the hemostatic effect of hemocoagulase agkistrodon in elderly patients undergoing laparoscopic cholecystectomy and to analyze its influence on coagulation function and its safety.Methods A prospective,randomized,double blind and controlled research was conducted in 60 patients aged over 65 years.Patients were divided into 2 groups:the study group and the control group (n =30 each group).Patients in the study group were injected with 2 U hemocoagulase agkistrodon intravenously 20 minutes before operation and with 1 U hemocoagulase agkistrodon 4 hours after operation.Patients in the control group were injected with physiological saline instead of hemocoagulase agkistrodon.The intraoperative intraperitoneal hemorrhage and intraperitoneal drainage at 24 hours after operation were recorded.The changes in bemagglutination and safety were observed.Results 59 cases were finished in this study and 1 case was eliminated.The volume of intraoperative hemorrhage was less in the study group than in the control group [(53.6±68.1) g vs.(88.1±79.7) g,t =2.08,P=0.038].There was no significant difference in the volume of intraperitoneal drainage at 24 hours after operation between the study group and the control group [(71.7±113.3) g vs.(89.0±104.7) g,t =1.69,P=0.075].The hemoagglutinationindexes were similar between two groups and no thrombosis occurred.There was no significant difference in the time of hospital stay between the study group and the control group [(5.2±1.4) days vs.(5.3±1.7) days,t=0.52,P=0.61].No adverse event was reported.Conclusions Hemocoagulase agkistrodon has relatively good hemostatic effects and safety for the elderly patients undergoing laparoscopic cholecystectomy.

Objective To investigate the prevalence of feeding intolerance (FI),and to explore the FI within 7 days of ICU admission in association with clinical outcome in critically ill patients.Methods The adult patients from 14 general ICUs in Zhejiang Province with an expected admission to ICU for at least 24h were recruited from March 2014 to August 2014,and all clinical,laboratory,and survival data were prospectively collected.The AGI (acute gastrointestinal injury) grade was daily assessed based on gastrointestinal (GI) symptoms,feeding details and organ dysfunction within the first week of ICU stay.The intra-abdominal pressures (IAP) was measured using AbViser device.Results Of 550 patients enrolled,418 were assessed in GI symptoms and feeding details within 7 days of ICU stay.The mean age and SOFA score were (65.1 ± 18.3) years and (8.96 ±4.10),respectively.Of them,355 patients (84.9％) were under mechanical ventilation support,and 37 (8.85％) received renal replacement therapy.The mean length of time for enteral feeding was (30.8 ±26.2) h,and the prevalence of FI on the 3rd and 7th day of ICU stay accounted for 39.2％ and 25.4％,respectively.Compared to those with FI within 7 days of ICU stay,the patients without FI had higher rate of successively weaning from mechanical ventilation (21.3％ vs.5.7％,P =0.003) and higher rate of withdrawal of vasoactive medication (45.5％ vs.20.0％,P =0.037),as well as lower mortality rate of 28-day (24.4％ vs.38.7％,P =0.004) and 60-day (29.6％ vs.44.3％,P =0.005).In multivariate Cox regression model with adjustment for age,sex,participant center,serum creatinine and lactate,AGI grade on the first day of ICU stay,and comorbidities,the FI within 7 days of ICU stay (x2 ≥ 7.24,P ＜ 0.01) remained to be independent predictors for 60-day mortality.After further adjusted for SOFA score,the FI within 7 days of ICU stay (HR =1.71,95％ CI:1.18-2.49;P =0.006) and AGI grade on the first day of ICU stay (HR =1.33,95 ％ CI:1.07-1.65;P =0.009) could provide independent prognostic values of 60-day mortality.Conclusions There is high rate of FI occurred within 7 days of ICU stay,and is significantly associated with worse outcome.In addition,this study also provides evidence to further support that measurement of gastrointestinal dysfunction could increase value of SOFA score in outcome prediction for the risk of 60-day mortality.

OBJECTIVETo analyze the incidence trends and characteristics of lymphoma in Beijing, 1998-2010.

METHODSTotal of 9 763 new cases diagnosed as lymphoma in 1998-2010 were extracted from the population-based database of Beijing Cancer Registry, covering population of 151 601 066 person-years. Incidence, age-adjusted incidence, cumulative incidence, truncated incidence and annual percentage change (APC) were calculated. The gender-specific, age-specific and pathology-specific incidence trends were analyzed.

RESULTThe incidence rate of lymphoma was 6.48/100 000 (9 763/150 720 187) during the period of 1998-2010, increased from 3.78/100 000 (410/10 850 626) in 1998 to 8.88/100 000 (1 111/12 518 114) in 2010 with an increasing rate of 136.17% (APC = 5.21%, P < 0.05). The incidence rate of Hodgkin lymphoma increased from 0.25/100 000 (27/10 850 626) in 1998 to 0.47/100 000 (59/12 518 114) in 2010 with an increasing rate of 88.00% (APC = 4.33%, P < 0.05). The incidence rate of non-Hodgkin lymphoma was increased from 2.89/100 000 (314/10 850 626) in 1998 to 5.93/100 000 (742/12 518 114) in 2010 with an increasing rate of 105.19% (APC = 4.19%, P < 0.05) . During the period of 1998-2010, the incidence of lymphoma was 7.78/100 000 (7 125/91 621 898) in urban areas and 4.47/100 000 (2 638/59 098 289) in rural areas, 7.40/100 000 (5 632/76 121 672) in males and 5.54/100 000 (4 131/74 598 518) in females.

CONCLUSIONThe incidence of lymphoma keeps increasing in 1998-2010, and the incidence was higher in males than females, urban areas than rural areas. The incidence patterns of Hodgkin lymphoma and non-Hodgkin lymphoma were different.
