Objective To investigate the early post-operative nutritional support for kidney transplant recipients.Methods Totally 67 patients who received early post-operative nutrition supports were randomly divided into three groups:group A (n = 24,relatively high nitrogen intake),group B (n = 25,intermediate nitrogen intake) and group C (n = 18,relatively low nitrogen intake).Two weeks after operation,albumin,hemoglobin,the nutrition indieators,serum lipids,and renal function 1 day before operation and 2 weeks after operation were evaluated. Results Body weight was significantly different among three groups;the nitrogen balance in group A was significantly better than those in groups B and C (P <0.05);albumin and hemoglobin were not significantly different between group A and group B (P > 0.05),but were significantly higher than those in group C (P < 0.05).The renal function in group C was significantly better than those in group A and group B (P < 0.05).The triglyceride level was not significantly different among three groups,while the cholesterol level in group A was significantly higher than those in group B and group C (P < 0.05),but not between group B and group C.Conclusion Proper nitrogen intake in early post-operative nutrition support can improve the recovery of renal function and nutritional status in kidney transplant recipients.

Objective To investigate the MRI manifestations of cerebral glioma involving corpus callosum,and to enhance the ability to diagnosis and differential diagnosis.Methods Thirty four cases of cerebral glioma involving corpus callosum under went plain and Gd DTPA enhanced MR scans.The MRi findings of these gliomas were compared with operation and pathology.Results Gerebral gliomas involving corpus callosum presented as long T 1 and long T 2 homogeneous or inhomogeneous signal intensity and obvious mass effect.The MRI findings of Gd DTPA enhanced MR scans were obvious enhancement,slight enhancement or no enhancement accouding to different pathological kinds of gliomas."Butterfly signs" and "semi butterfly signs" were the reflections when gliomas of corpus callosum invaded two sides or one side of cerebral hemisphere.These two signs were significant markings in the diagnosis of cerebral gliomas in corpus callosum region.Conclusions Cerebral gliomas involving corpus callosum are intracranial tumors with special location.MRI has significant clinical value in the diagnosis and differential diagnosis of this kinds of tumour.

ObjectiveTo develop a analytical method of three phenoxyalkanoic acid herbicides,MCPA,2,4-D and dichlorprop,in grape leaf using dichloropropyl esterification and gas chromatography with electron-capture detection.MethodsSamples were pounded to pieces,added into internal standard 2,4-dichlorophenylacetic acid,acidified and extracted with ethyl ether.The extracts were cleaned up by liquid-liquid partition.The cleaned organic solutions were evaporated and the residues were dichloropropylated using sulfuric acid and 1,3-dichloropropan-2-ol.The formed esters were analysed by gas chromatography.ResultsThe detection limits of MCPA,2,4-D and dichlorprop in grape leaf were 20ng/g,20ng/g,and 30ng/g,respectively.The concentritions of herbicides in grape leaf were linear over the ranger 100~1000ng/ml.The average recoveries of MCPA,2,4-D and dichlorprop in spiked grape leaf at concentrition of 200ng/g were 98.8%,101.3% and 103.1% with the coefficients of variation 11.4%,11.0% and 9.3% respectively.ConclusionThis method is sensitive and accurate for determination of these three herbicides in poisoned grape leaf.

Objective To investigate the changes of the serum levels of necrosis alpha (TNF-o)and interleukin 10( IL-10 )in patients with hypertensive renal damage,and to study the correlation of TNF-α and IL-10 with the hypertensive renal damage. Methods Seventy three patients with primary hypertension were divided into two groups according to their urinary albumin excretion rate(UAER): simple hypertensive group( n = 37 ),hypertensive renal damage group(n =36). TNF-α and IL-10 were measured using radioimmune assay. Thirty normotensive healthy persons were selected as normotensive control group. Results TNF-α were significantly higher and IL-10 significantly lower in patients with essential hypertension than those in normotensive control group(TNF-α: [2.91 ±0.94]μg/L vs [0.98 ±0.35]μg/L,P<0. 05;IL-10:[ 19.2 ±5.8]μg/L vs [28.6±5. 7] μg/L,P <0. 01 ) ,and in patients with hypertension,those with renal damage had higher TNF-α and lower IL-10 than those without( TNF-α: [ 3.75 ± 0. 88 ] μg/L vs [ 1.87 ± 0. 58 ] μg/L, P < 0. 01; IL-10: [ 15. 4 ± 4. 3 ]μg/L vs [ 22. 5 ± 5.9 ] μg/L, P < 0. 01 ), with statistically significant difference between groups ( P < 0. 01 ).TN F-α and IL- 10 were found to have correlations with UAER ( r = 0. 703, P < 0. 001; r = - 0. 613, P < 0. 001 ),but no correlation with the level of blood pressure. Conclusion TNF-α increased and IL-10 decreased significantly in patients with hypertensive renal damage, which indicates that the imbalanced cytokine network may play a role in the pathological mechanisms of hypertensive renal damage.

BACKGROUND: Twin-block appliance has been confirmed to efficiently change hard tissue and the profile of soft tissue.Whether a linear relationship exists between soft tissue and hard tissue changes remains unclear.OBJECTIVE: To evaluate the face convexity changes of soft and hard tissues after Twin-block appliance therapy and compare with controls.METHODS: Thirty-one class Ⅱ division 1 malocclusion subjects with hand-wrist radiographs in FG-G stage were selected.Among the 31 patients,17 received Twin-block appliance therapy,serving as experimental group,and the remaining 14 subjects abandoned treatment,serving as control group.Cephalometric radiographs of each included subject were taken prior to and after treatment or observation.Face convexity of soft and hard tissues,as well as the face convexity changes,was compared between the experimental and control groups.Linear regression equation was employed to analyze the linear association between soft-and hard-tissue changes.Regression equations of experimental and control groups were compared.RESULTS AND CONCLUSION: Prior to and after Twin-block appliance therapy,a significant correlation existed between the position changes of superior and inferior alveolar sockets relative to the nose and mandible,and the position changes of upper and lower lip pits relative to the nose and mandible,i.e.,there was a linear correlation between A-E change and Ss-E change,and between B-E change and Si-E change.The largest Pearson's correlation coefficient(0.839)appeared between Si-E change and B-E change,indicating the best correlativity between these two changes.Statistical analysis revealed that the linear equations of face convexity changes of soft and hard tissues after Twin-block appliance therapy were Si-E=0.745 B-E,Ss-E=0.276 A-E.These linear equations would be helpful to explain mandible growth and face convexity change after Twin-block appliance therapy and predict the prognosis of face convexity change.

Objective To evaluate the value of fecal high mobility group box-1 (HMGB 1 ) in early diagnosis and prediction of the severity of neonatal necrotizing enterocolitis (NEC). Methods From July 2013 to June 2015 , the neonates who had distention, vomit, or gross blood in stool and were suspected of NEC were recruited as NEC group while hospitalized children without abdominal distension, vomiting, bloody diarrhea, or other gastrointestinal symptoms were recruited as the control group. Stool samples were collected on day 1 , 3 , 5 and 7 after admission. The level of HMGB 1 was measured by enzyme linked immunosorbent assay (ELISA). Results In the end, there were 46 cases in NEC group and 15 cases in control group. In NEC group, 29 cases were conifrmed of stageⅠof NEC by abdominal radiograph within 24 h after hospitalized, all of them were deteriorated to stageⅡphase in 4 days, and 10 cases were deteriorated to stageⅢ. Seventeen cases were conifrmed of stageⅡby abdominal radiograph within 24 h after hospitalized, 7 cases were deteriorated to stageⅢ. In 17 stageⅢcases, 11 cases received surgical treatment and 6 cases gave up. Eight cases survived and 3 died after surgery. The levels of HMGB 1 in NEC group on day 1 , 3 , 5 and 7 after hospitalized were higher than those in control group (P0 . 05 ). With the exacerbation of NEC from stage I toⅢ, the levels of HMGB 1 increased gradually (P0 . 05 ). Conclusions With the exacerbation of NEC, the level of HMGB 1 is gradually increased, which indicates that it has certain clinical value in early diagnosis and prediction of severity of NEC.
