ABSTRACT
Objective To explore the effects of timing of enteral nutrition (EN) in the severe acute pancreatitis (SAP).Methods The rabbit model of SAP was constructed,and 40 experimental rabbits were divided randomly into the experimental group (20 rabbits) and the control group(20 rabbits).(1) The parenteral nutrition (PN) was administered to rabbits in the experimental group,and then EN was administered after bowel sound restoration.(2) EN was administered to the rabbits in the control group at hour 12 after PN.The values of TNF-α,IL-6 and IL-8 on post-modeling day 1,3 and 7 and intra-abdominal pressures at hour 1 before EN and on post-modeling day 1 and 3 were respectively examined.The experimental animals were sacrificed on post-modeling day 7 and 10.The expression of nuclear factor-kappa B (NF-κB) was detected by immunohistochemistry and bacteria from mesenteric lymph nodes were cultured.The measurement data with normal distribution were presented as (x) ± s.The trend comparison between groups and pairwise comparison were analyzed using the repeated measures ANOVA and t test.Results The 40 rabbit models of SAP were constructed successfully.(1) The results of serum test showed that the values of TNF-α,IL-6 and IL-8 in the experimental group on post-modeling day 1,3and 7 were (6.9 ±2.1)ng/L,(5.9 ± 1.8) ng/L,(5.3 ± 1.8) ng/L and (109 ± 17) ng/L,(96 ± 16) ng/L,(83 ± 17)ng/L and (89 ±20)ng/L,(78 ±21)ng/L,(70 ± 19)ng/L,respectively.The values of TNF-α,IL-6 and IL-8 in the control group on post-modeling day 1,3 and 7 were (7.4 ± 1.5) ng/L,(7.1 ± 1.6) ng/L (6.8 ±1.7) ng/L and (101 ± 19) ng/L,(98 ± 18) ng/L,(93 ±20) ng/L and (91 ± 14) ng/L,(91 ± 16) ng/L,(83 ±19)ng/L,respectively.There were significant differences in the changing trends of TNF-α and IL-6 between the 2 groups (F =7.947,19.386,P < 0.05),with no significant difference in the changing trend of IL-8 between the 2 groups (F =2.756,P > 0.05).(2)The intra-abdominal pressures in the experimental group at hour 1 before EEN and on post-modeling day 1 and 3 were (3.5 ± 1.6) cmH2O (1 cmH2O =0.098 kPa),(4.3 ± 1.7) cmH2Oand (3.6 ± 1.8) cmH2O,which were significantly different from (4.9 ± 1.9) cmH2O,(5.7 ± 2.2) cmH2O and (4.5 ± 1.6)cmH2O in the control group (F =7.042,P <0.05).(3) The expression of NF-κB in the tissues of pancreas was localized mainly in the cell nucleus.The expression of NF-κB in the experimental group on postmodeling day 7 was 5.0 ± 2.7,which was significantly different from 7.0 ± 2.9 in the control group (t =2.236,P < 0.05).(4) The amount of bacteria culture from mesenteric lymph nodes in the experimental group on postmodeling day 7 and 10 were (4.7 ±0.9) × 103 cfu/g and (4.1 ±0.7) × 103 cfu/g,which were significantly different from (5.5 ± 1.0) × 103 cfu/g and (4.6 ± 0.7) × 103 cfu/g in the control group (t =2.382,2.126,P <0.05).Conclusion The selective timing of EN can effectively improve the recovery of rabbits with SAP,and the efficacy of EN administering based on the recovery of bowel function may be better than immediate EN administering.
ABSTRACT
Objective To study the impact of antiviral therapy on patients with postoperative intrahepatic recurrence of hepatitis B related hepatocellular carcinoma (HCC).Methods According to the inclusion and exclusion criteria,65 patients with HCC who were managed in our hospital from January 2004 to December 2011 for intrahepatic recurrence and had indications for antiviral treatment were included into this study.The patients were divided into two groups ; the antiviral and the control groups.Relevant data between these two groups such as cumulative survival after recurrence,Child-Pugh grade,HBV-DNA,HBeAg,AFP at the time of recurrence and 6 months later were studied.An analysis on multiple-factors was carried for survival after recurrence at 2 years.Results When compared with the control group,the antiviral group had better cumulative survival in all the cases and in the TACE cases (P < 0.05 respectively).The cumulative survival in the RFA cases was not significantly different between the two groups (P > 0.05).A comparison was carried out in patients who received antiviral therapy which was combined with one or more other therapies (TACE,RFA,reoperation):(a) antiviral therapy only (8 patients) ; (b) combined with one therapy (22 patients) ; (c) combined with two therapies (10 patients) ; (d) combined with three therapies (2 patients).All P values of a:b,a:c,a:d,b:c,b:d were less than 0.05.The blood HBV-DNA of the two groups was significantly different at the time 6 months after recurrence (P < 0.05).The results of multivariate analysis showed the 2-year survival was significantly correlated with recurrent tumor size,primary tumor class,antiviral therapy or not after recurrence,presence of absence of cirrhosis.All P values were less than 0.05.Conclusions Antiviral therapy had remarkable clinical impact on HCC patients with postoperative intrahepatic recurrence and with indication for antiviral treatment.Patients had better prognosis if antiviral therapy was combined with one or more other therapies.
ABSTRACT
Objective To summarize the clinical features of pancreatic injury in children,and to explore the suitable methods for its diagnosis and treatment.Methods A retrospective analysis of children with pancreatic injury within the 15 years was carried out.Clinical injury severity and following-up data were collected.Correlationship between injury severity,treatment method and successful rate was analyzed.Results Eleven children aged 4 to 14 years old were diagnosed as pancreatic injury:two had GradeⅠinjury,three GradeⅡ,five GradeⅢ,and one GradeⅣ.CT scan was used in 7 children,and 5 had positive sign.Patients with GradeⅠand GradeⅡinjuries were successfully cured without surgery.Three children with GradeⅢinjury were initially treated without operation,but two developed a large symptomatic pseudocyst and were cared through operation,and another one died.The other two children with GradeⅢwho underwent a distal pancreatectomy cured without complications.A patient with GradeⅣinjury was treated by Berne operation and died. Conclusion The management of pancreatic injury in children should be individualized depending on diagnosis time and injury type.A repetitive CT scan was helpful within 24h after injury.Distal pancreatectomy was a safe and effective for those with GradeⅢinjury.
ABSTRACT
Objective To explore the relationship between t he pancreatic vascular abnormalities and pancreatic lesions, complications and pro gnosis in acute necrotic pancreatitis (ANP).Methods Seldinger procedure, DSA angiography was carried out in ANP pa tients to evaluate the alterations of pancreatic blood vessel, results were anal yzed against clinical data.Results In 40 out of 69 cases, the pancreatic blood supply showed abnormal in angiogram, t here were features of interuption, stenosis and complete obstruction. The degree of lesions and complications showed statistically significant correlation ( P
