Objective To investigate the effects of nasojejunal feeding plus nasogastric tube decompression in severe hypertensive intracerebral hemorrhage complicated with gastroparesis.Methods Fifty-six cases of severe hypertensive intracerebral hemorrhage complicated with gastroparesis admitted to hospital from January 2011 to June 2014 were chosen as study group, while the 52 cases of similar patients admitted to hospital from January 2007 to December 2010 were chosen as control group.Nasojejunal feeding and nasogastric tube decompression were given to the study group.Nasogastric enteral nutrition support therapy was firstly given to the control group conventionally,after 15 days if they still could to be tolerant of the enteral nutrition,then parenteral nutrition therapy were adopted.The weight, serum albumin, prealbumin and hemoglobin circumstances of the two groups were determined and the complications were recorded.The patients were followed up according to activity of daily liying(ADL) after 3 months.Results There was no significant difference on the average body weigh between two groups before treatment.The average body weight of the study group was significantly higher than that of the control group after 4 weeks treatment((57.2±5.3) kg vs.(52.8±4.9) kg,t=4.33,P＜0.01).The serum albumin, pre albumin and hemoglobin of 3 week, four week after treatment were significantly higher than those of the control group(serum albumin of 3 week: (34.5±3.3) g/L vs.(30.7±3.1) g/L;erum albumin of four week:(37.8±3.8) g/L vs.(34.1 ± 3.4) g/L;serum prealbumin of 3 week:(202.3± 16.7) g/L vs.(179.6 ±15.2) g/L;serum prealbumin of four week: (216.9±17.1) g/L vs.(203.1±15.4) g/L;hemoglobin of 3 week : (119.4± 12.1) g/L vs.(107.7 ± 11.3) g/L;hemoglobin of four week : (126.2± 12.8) g/L vs.(113.5 ±11.9) g/L).Nutritional status of study group was significantly better than that of the control group(t=6.16, 5.32,7.37,4.85,5.18,5.32;P＜0.01), and complications was significantly less than that of the control group (P＜0.05).After three months, the good prognosis rate of study group (80.36％ (45/56)) was significantly higher than that of the control group (6 1.54％ (32/52)), the difference was statistically significant (x2 =4.67, P ＜0.05).Conclusion Nasojejunal feeding plus nasogastric tube decompression for patients with severe hypertensive intracerebral hemorrhage with gastroparesis can improve nutritional status, enhance their body resistance, reduce the incidence of complications, and improve their prognosis.

Objective To investigate the effects of total anthraquinone in rheum on aquaporin 2 and aquaporin 4 expression in rat kidney and explore its diuresis mechanism.Methods Thirty-two SD rats were randomly divided into control group,low dose group,medium dose group and high dose group.Total anthraquinone in rheum was administered to rats at different doses.Urinary volume of 24 h,Na+ concentration and osmolality were detected.Rats were sacrificed 5 days later.Blood samples were taken from the abdominal aorta to detect blood biochemical indicators. Kidneys of rats were removed to detect AQP2, AQP4 expression through immunohistochemistry,Western blot,and RT-PCR. Results Compared with control group,there were significantly increased 24 h urine output of rats in medium and high dose group[(16.21±1.96),(18.16±1.8) ml vs(13.85±1.25)ml,P＜0.05].24 h urine output in low-dose group did not change significantly.AQP2 protein and mRNA expression were significantly decreased in rats'kidneys of medium and high dose group (P＜0.01),The AQP4 protein and mRNA expression was significantly down-regulated in high dose group (P＜0.01).In medium does group,the AQP4 protein expression was down-regulated (P＜0.01),without significant decrease in the mRNA expression.Protein and mRNA expression of AQP2 and AQP4 did not significantly change in low dose group.Conclusion Total anthraquinone in rheum can reduce the expression level of AQP2 and AQP4 in rat kidney,which is probably one mechanism of diuresis caused by rheum.

Objective To estimate the relationships between lipoprotein-associated phospholipase A2 (Lp-PLA2) activity and cerebral feeding artery athemsclemsis.Methods The blood samples were obtained from 148 atheroselerosis patients (atheroselerosis group) and 40 normal controls (control group).Activity of plasma Lp-PLA2 and traditional factors were determined.Logistic and regression model was adopted to analyze the roles of Lp-PLA2 and generally inflammatory risk factors in athemselemsis.Results Lp-PLA2 activity was significantly higher in atheroselerosis group than that in control group [(29.84±3.50)lesion number showed positive correlation with Lp-PLA2 (r=0.491,P＜0.01 and r=0.249,P=0.026).Adjusted other risk factors,Lp-PLA2 was an independent risk factor in cerebral feeding artery atherosclerosis.Conclusion Lp-PLA2,a novel inflammatory marker,is an independent risk factor of cerebral feeding artery atherosclerosis.

Objective To sum up the clinical characteristics and the diagnostic and therapeutic principle of severe hypertensive intracerebral hemorrhage complicated with gastroparesis.Methods The clinical data of 51 patients with severe hypertensive intracerebral hemorrhage complicated with gastroparesis were retrospectively analyzed.Results Of the patients who died,3 died of over-severe hemorrhage,and 1 died of acute respiratory distress syndrome caused by aspiration,as well as one died of respiratory failure resulting from pulmonary infection after aspiration.None died of digestive tract complication.Twenty-one patients(41.18％) needed feeding via naso-intestinal tube.Thirty patients (58.82％) were recovered within two weeks and 14 patients (27.45％) were recovered within the third week,and those who recovered beyond three weeks accounted for 3.92％ (n =2).Conclusion The gastroparesis complicating severe hypertensive intracerebral hemorrhage is considered as a functional disorder rather than mechanical obstruction.It is mainly on the basis of symptoms and signs in combination with gastroscopy or radiography that the diagnosis can be made.The conservative treatment (including nasal feeding in some patients) should be applied to the disorder.

Objective To investigate the application value of methylene blue excretion test in early reasonable nutritional support for severe traumatic brain injury.Methods One hundred and thirty-three cases of severe traumatic brain injury admitted to hospital from January 2010 to June 2012 were chosen as treatment group,while the 127 cases of similar patients admitted to hospital from January 2007 to December 2009 were chosen as control group.Patients in treatment group underwent methylene blue excretion test in 3 days,8 days,15 days after injury,and the nutritional support ways were determined according to the elimination time of methylene blue in patients' urine.The control group conventionally receive enteral nutrition support therapy firstly,after 15 days if they still cannot be tolerant of the enteral nutrition,then parenteral nutrition therapy were adopted.The weight,serum albumin and hemoglobin circumstances of the two groups were determined and the complications were recorded.Glasgow coma score (GCS) of 3 months after injury were followed up.Results There was no significant difference on the average body weigh between these two groups before treatment.The average body weight of the treatment group was significantly higher than that of control group after 3 months treatment((56.3 ± 5.5) kg vs.(52.6 ± 5.3) kg,t =5.93,P ＜ 0.01).The serum albumin and hemoglobin of 14 d,21 d after injury were significantly higher than those of the control group (serum albumin of 14 d:(32.7 ±3.4) g/L vs.(28.8 ±3.1) g/L; serum albumin of 21 d:(34.3 ±3.8) g/L vs.(30.7 ±3.3) g/L;hemoglobin of 14 d:(113.4±12.5) g/L vs.(102.2 ±11.6) g/L;hemoglobin of 21 d:(118.5 ±13.3) g/L vs.(106.7 ± 12.4) g/L.Nutritional status of treatment group was significantly better than that of the control groupall P ＜ 0.05).After three months,the effective rate of treatment group (93.23％ (124/133)) was significantly higher than that of the control group (84.25％ (107/127)),the difference was statistically significant (x2 =5.29,P ＜ 0.05).Conclusion Determining the early reasonable nutrition support ways for patients with severe traumatic brain injury according to the elimination time of methylene blue in the urine,can provide comprehensive nutrition to patients,enhance their body resistance,reduce the incidence of complications,and create an important clinical value for improving prognosis.

BACKGROUND:Abnormal immunological function is possibly observed after cardiac valve replacement. However, effect of continuous venovenous hemofiltration on immunological function after cardiac valve replacement is rarely reported.
OBJECTIVE:To observe the effect of continuous venovenous hemofiltration on the cellular immune function in patients with multiple organ dysfunction syndrome after cardiac valve replacement.
METHODS:Thirty-one patients with multiple organ dysfunction syndrome after cardiac valve replacement in Xijing Hospital, the Fourth Military Medical University of Chinese PLA, from August 2008 to July 2009, were included in this study. They were treated with continuous venovenous hemofiltration using AV600 hemofilter and were divided into two groups:survival group (17 survivors) and death group (14 deaths). In addition, 16 healthy blood donors served as the control group.
RESULTS AND CONCLUSION:The duration of acute renal failure before continuous venovenous hemofiltration of survival group was significantly lower than that of death group (P<0.05). Before continuous venovenous hemofiltration, the CD4+/CD8+ratio and Th1/Th2 ratio of survival group and death group were lower than that of control group (P<0.05), and lymphocyte apoptosis rate and Fas/FasL antigen expression were higher than that of control group (P<0.05). This evidence suggested the presence of immunosuppression state and Th1/Th2 disbalance. During continuous venovenous hemofiltration, the CD4+/CD8+ratio and Th1/Th2 ratio of survival group were gradual y increased (P<0.05), while lymphocyte apoptosis rate and Fas/FasL antigen expression were gradual y decreased (P<0.05) at 24 hours. The above changes were observed in both survival group and death group, but emerged latter in death group. Continuous venovenous hemofiltration can improve cellular immune function, maintain the balance of T lymphocyte subsets and Th1/Th2, down-regulate Fas/FasL expression on the surface of lymphocyte membrane, and decrease lymphocyte apoptosis rate in patients with multiple organ dysfunction syndrome after cardiac valve replacement. Early continuous venovenous hemofiltration can improve patients’ prognosis.

Objective To discuss the treatment of femoral fracture combined with ipsilateral acetabular fracture and femoral head dislocation and the reasons for the misdiagnosis of the injury. Methods According to AO classification, there were 3 cases of type 32A, 2 of type 32B, and 1 of type 32C, who were treated with internal fixation of interlocking nails. There was 1 case of type 33C3, who was treated with femoral condyle supporting plate. There were 2 cases of type 31A2, who were treated with DHS. According to the Letournel classification, fracture of the acetabular posterior wall was found in 8 cases and fracture of the acetabular posterior column and wall in 1 case. All the cases of acetabular fracture were treated with internal fixation of titanium alloy reconstructive plates. Delayed diagnosis was found in 2 cases in this group. Results The 9 patients were followed up for 13 to 38 months (averaging 22.4 months). According to the American criteria, 8 cases was rated as excellent, and 1 case as good, with thd total excellent and good rate being 100%. Conclusions Femoral fractures combined with ipsilateral acetabular fracture and femoral head dislocation are a rare, complex and serious injury. They usually involve other organs, and are easy to be misdiagnosed. The surgeries should be done as early as possible. The internal fixation plays a key role in management of the fracture of acetabular.
