The formation of carcinomas of liver, lung and kidney in rats by feeding aminopyrine (AP) plus sodium nitrite (Na NO2) in diet was investigated. 72 young Wister rats were divided into A,B,C,D group. Group A was set as control receiving basal diet and tap water. Another 3 groups were given basal diet containing AP plus Na NO2 (2g/kg each). However, group B was given tap water, group C ascorbic acid solution, group D sea buckthorn (Hippophae rhamnoides L.) juice for drinking. After 38 week's feeding, group B developed tumors in the livers (17/17), lungs (6/17) and kidneys (4/17) and the average life-span was 195 days, group D delayed the development of tumors and the average life-span was 270 days, significantly longer than that of group B (195 days, p

Objective To explore MRI of sacroiliac joint.Methods MRI was applied to 33 patients on transaxial FSE T2WI and SE T1 WI,coronal FSE T2 WI and two coronal FSPGR.Results Sacroiliac joints of 7 patients were normal,and all the sequences could directly show the cartilage of normal sacroiliac joints.The other 26 patients suffered from ankylosing spondylitis(AS),and cartilage abnormality appeared in 42 sacroiliac joints from 52 joints.The irregular thickened or tortuous ones replaced the linear intermediate signals on T1WI and T2WI.Conclusion Such measures do good to MRI of normal sacroiliac joint structure and pathological changes as optimization of scanning parameters,selection of proper scanning method and coil,as well as application of T2WI and FSPGR in phase fat suppression technology.

AIM: To investigate the situation of patients with mechanical ocular trauma and the possible influencing factors related to the prognosis.METHODS: Totally 260 patients(286 eyes) with mechanical ocular trauma from January 2011 to January 2016 in Xiaogan Central Hospital were selected and retrospective studied.Sociology and clinical data including gender,age,career,injury causes,injury nature,treatment time and visual acuity on admission in these patients were univariate analyzed,then the positive factors were analyzed using Logistic regression.RESULTS: The middle-aged and young males were domain in 260 patients.The causes were mainly sharp instrument injury,while perforating injury of eyeball was the majority in injury nature.Univariate analysis showed that injury causes,injury nature,treatment time and eyesight on admission were influencing factors,while multivariate analysis by Logistic regression showed that visual acuity on admission and orbital contusion were independent influencing factors for patients ocular trauma.CONCLUSION: Ocular trauma is a majoy cause of monocular blind,there are close associations between prognosis of ocular trauma and orbital contusion and visual acuity on admission.But the majority of ocular trauma is preventable and treatable,the relevant measures should be developed to prevent the ocular trauma.

AlM: To analyze the correlation between tear film changes of allergic conjunctivitis and dry eye, then provide clinical references for better treatment.
METHODS: Fifty patients with allergic conjunctivitis were taken as the observation group, the control group was selected based on 1:1 case control theory, and we chose 50 health volunteers without ocular surface diseases, xerophthalmia and systematic diseases randomly, then fluorescein ( FL) staining, break-up time ( BUT) , Schirner l test ( SⅠt) , tear meniscus high ( TMH) and slit-lamp examinations were performed in the two groups.
RESULTS: ln the observation group, FL, BUT, Slt, TMH of right eyes and left eyes were statistically significant correlated ( P < 0. 05 ). FL and BUT were statistically significant between control group and observation group (P<0. 05). TMH and Slt has positive correlation, while FL and BUT has negative correlation and the differences were statistically significant (P<0. 05). CONCLUSlON: Due to inflammatory mediators participation, allergic conjunctivitis could lead to the stability changes of tear film which cause in dry eye. The stability changes of allergic conjunctivitis correlate to the damage degree of epithelium.

Objective To systematically review the efficacy of glutamine enriched nutrition support for patients with severe acute pancreatitis (SAP).Methods Database including PubMed,Embase,HighWire,Cochrane Central Register of Controlled Trials,Wanfang Database,CJFD and CBM were searched with glutamine,severe acute pancreatitis,SAP,谷氨酰胺,重症急性胰腺炎.Literatures published before March 2014 were searched.Randomized controlled trials containing the comparison of conventional treatment and glutamine enriched nutrition support were enrolled in the study,and then the literatures were screened and the data were extracted by 2 independent reviewers.The quality of the literatures was assessed,and the data were analyzed using the RevMan 5.2 software.SAP was diagnosed according to The revised Atlanta classificantion for acute pancreatitis or guideline for the diagnosis and treatment of SAP which was composed by the pancreatic surgery Branch of Chinese Medical Association.The count data were analyzed using the relative risk (RR) and 95％ confidence interval (95％ CI),and the measurement data were analyzed using standard mean difference (SMD) and 95 ％ CI.The heterogeneity of the data was analyzed using the I2 test.Results Ten literatures including 433 cases were enrolled in the study,and all of them were prospective randomized controlled studies.There were 218 patients treated by conventional methods (control group) and 215 patients received glutamine enriched nutrition support (experimental group).Compared with the control group,glutamine enriched nutrition support could elevate the albumin level,decrease the C-reaction protein level and shorten the hospital stay in the experimental group (SMD=1.00,-0.93,-0.71,95％CI:0.50-1.50,-1.25--0.61,-1.10--0.32,P＜0.05),glutamine enriched nutrition support could decrease the morbidity and mortality (RR =0.56,0.34,95％ CI:0.41-0.77,0.15-0.76,P ＜ 0.05) without increasing the expenses (SMD =0.03,95％ CI:-0.88-0.95,P ＞ 0.05).Conclusion Glutamine enriched nutrition support is superior to conventional methods for the treatment of SAP.

Objective:To investigate the effects of resuscitation with different fluids on hemodynamics,oxygen transport and extravascular lung water after acute hemorrhage in dogs. Method:Fifteen dogs were anesthetized and bled to a mean arterial pressure of 4.67 kPa to develop the hemorrhagic shock model.Then the animals were infused with one of three randomly selected fluid:lactated Ringer's solution, blood and polygeline.The terminal point of fluid resuscitation was at the level of PAWP of 2.0 kPa. Hemodynamics, oxygen transport and extravascular lung water values were measured. Result:colloids fluids infusion has more better efficacy and less extravascular lung water than crystalloids fluids infusion in hemorrhagic shock resuscitation,and polygeline infusion could restore hemodynamics better, meanwhile blood infusion could restore oxygen transport better.

ObjectiveTo evaluate the efficacy of the high-flux dialysis on maintaining hemodialysis patients. Methods60 hemodialysis patients were randomly divided into the ordinary PMMA membrane dialyzer group,the ordinary polysulfone membrane dialyzer group and the high-flux dialyzer group with 20 patients in each group.Before and after the single hemodialysis,the removing effect of serum β2- microglobulin (β2-MG)in the 3 kinds of dialyzer,and cholesterol,triglyceride,low density lipoprotein changes after 6 months were compared. ResultsThe ordinary PMMA membrane dialyzer group and high-flux dialyzer group can reduce the concentration of β2-MG,while the high-flux dialyzer group showed more significant effect.On the aspect of lipid metabolism,in the high-flux dialyzer group,serum total cholesterol,triglycerides and LDL levels decreased significantly,while the ordinary dialysis group had no significant change. ConclusionsThe high-flux dialysis can improve the dialysis efficiency,life quality and reduce the complications of patients.
