The myelodysplastic syndrome(MDS)is a group of clonal haematopoietic stem cell diseases characterized by ineffective haematopoiesis,dysplasia and aberrational expression of cell surface markers.Therefore,immunophenotyping of blast cells,granulocytes and monocytes is helpful to distinguish between MDS and non-MDS.The immunophenotyping is a complicated process.So the uniform diagnostic standard is the key to the comparabe and reliable results.

Objective To investigate the value of Multi-slice Spiral CT Angiography (MSCTA)in diagnosis of superior mesenteric artery (SMA)diseases.Methods The image features of SMA diseases in 40 patients were reviewed retrospectively using volume rendering (VR),multiplanar reconstruction (MPR),curved planar reconstruction (CPR),maximum intensity projection and other post-processing reconstruction technique.Results 16 patients have SMA ischemia including 8 cases of SMA acute occlusion;1 case of acute occlusion with small intestinal ischemic necrosis who has had surgery to remove the necrotic intestine.8 cases of SMA chronic occlusion;10 cases of spontaneous isolated dissection of SMA;7 cases of true aneurysm of SMA;1 case of SMA pseudoaneurysm associating with infective endocarditic;3 cases of SMA ulcer,including 1 case of inferior mesenteric artery (IMA)severe stenosis;2 cases of severe stenosis of celiac trunk;1 case of occlusion of IMA. In total of 40 cases,13 were with collateral circulation associating with SMA diseases,of which 4 were SMA chronic occlusion,3 were SMA acute occlusion,1 was spontaneous isolated dissection of SMA,1 was SMA pseudoaneurysm,1 was IMA stenosis,1 was IMA occlusion and 2 were celiac trunk severe stenosis,which was included collateral circulation of the anterior and posterior arterial arcades in 3 cases,collateral circulation of the dorsal pancreatic artery in 2 cases,Riolan’s arcade in 10 cases.Conclusion MSCT could clearly display SMA diseases and the establishment of collateral circulation,and evaluate intestinal ischemia.

Objective To explore the effect of immobilization with plaster cast applying in children's rehabilitation after knee arthroscopic surgery,and discuss the clinical significance of immobilization with plaster cast in children's rehabilitation after knee arthroscopic surgery.Methods A total of 72 objectives suffered from knee joint diseases were chosen and received knee arthroscopic surgery from January 2013 to November 2014.They were classified into the experimental group and the control group with the random digit table with 36 patients in each group.The control only underwent the regular rehabilitation exercise.The experimental group was given fixation with plaster caster before they got rehabilitation exercise.The three indexes such as pain degree,the compliance of children knee function exercise and the range of knee motion in different time courses were compared after operation.Results The VAS pain scores of the experimental group and the control group were (2.12±0.70),(2.37±0.61) respectively with statistical significance,P＜0.05.On the third day,one week and two weeks after operation,the complete compliance of children with knee function exercise was 83.3％ (30/36) vs.8.3％ (3/36),97.2％ (35/36) vs.22.2％ (8/36),97.2％ (35/36) vs.22.2％ (8/36) in the experimental group and the control group,Z values were-6.343,-6.400,-6.400,P＜ 0.01.On the second,third and fourth weeks after operation,the good rates of knee motion range in the experimental group and the control group were 50.0％ (18/36) vs.16.7％ (6/36),94.4％ (34/36) vs.83.3 (30/36),97.2％ (35/36) vs.81.6％ (31/36),Z values were-3.345,-2.861,-2.012,P＜0.01.Conclusions The use of immobilization with cast plaster in children's rehabilitation after the knee arthroscopic operation could significantly relieve the pain brought by the surgery,as well as increase the level of appliance of knee function exercises and improve the range of knee motion greatly.Therefore,it could help children to restore the knee function earlier and furthermore to promote life quality after receiving knee arthroscopic surgery.

Aim To study mechanisms of Stigma Maydis Polysaccharide(SMPS) on weight loss in experimental animals. Methods Observe changes of gastric discharge, intestinal peristalsis, biliary secretion, weight of gallbladder, body weight, appetite and cholecystokinin(CCK)level in plasm of rats and mice after being administrated with SMPS. Results SMPS increased the gastric residual rate of methyl orange and the intestinal propulsive rate,advanced first time black dejecta,increased the quantity of dejecta,decreased the weight of gallbladder in mice. SMPS also inhibited appetite,decreased body weight,prolonged gastric emptying,accelerated the propulsion speed of intestinal contents,promoted the biliary secretion,increased CCK level in plasm. Conclusion Mechanisms of weight loss are probably related to the increasing of CCK level in plasm and prolonging of gastric emptying,appetite inhibition, accelerating of intestinal peristalsis,the quantity increasing of dejecta.

Some hormones and glucocorticoid in chronic strss feedback are demonstrated to have significant effects on cancer progression.Recently,as a typical neuropeptide,gastrin releasing peptide (GRP) could mediate chronic stress to promote carcinogenesis through four conceivable mechanisms,such as regulating circadian rhythms,suppressing immunity system,acting as a mitogenic effect and mediating cancer-related psychiatric disorders,et al.

Objective To investigate the relationship between plasma visfatin levels and type 2 diabetes mellitus patients with carotid atherosclerosis.Methods 60 subjects were divided into 3 groups,T2DM no carotid atherosclerosis group (20 cases),T2DM with carotid atherosclerosis group (20 cases)and normal control group (20cases).Carotid IMT,plasma visfatin,waist circumference (WC),fasting plasma glucose (FPG),HbA1C,blood lipids,fasting serum insulin (FINS) were assayed or measured in all subjects.Results Plasma visfatin levels in T2DM with carotid atherosclerosis were significantly higher than those in normal control group and T2DM group [ (50.85 ± 20.14) ng/ml vs (18.50 ± 4.60) ng/ml,(50.85 ±20.14) ng/ml vs (35.52 ± 10.18) ng/ml,F = 105.983,P ＜0.01].Correlation analysis showed that plasma levels of visfatin were positively correlated with carotid IMT(r =0.476,P ＜0.01),TG (r =0.328,P ＜0.01),WC (r =0.206,P ＜0.05) and it was negatively correlated with HDL-C(r=-0.298,P ＜0.01).Conclusion Plasma visfatin was correlated with the development of macrovascular complications in T2DM patients,and it might be involved in the atherosclerotic pathological and physiological basis.

Objective The quantitation measurement of microalbuminuria was adopted to verify the feasibility of urinary microalbumin and ratio of mieroalbumin to creatinine (M/C) detection with dry hemieal method. Methods Totally 80 urine samples from the patients with clinically diagnosed dia-betes were tested by the immune quantitation method (immunoturhidimetric assay) and dry heroical method (HT2000 urine analyzer and test paper, Guilin Hnatong Company) simultaneously. Sarcosine oxidase method was applied to measuring creatinine level. Ten cases of outliers were removed. With the quantitation result of M/C as the reference standard, immune quatilyzation of the M/C as refer-ence, we compared and analyzed the results of the immune quantilization of urine microalbumin, those of the dry chemistry method and of the dry chemistry system detecting M/C. Results There was sig-nificant differences in test results of urinary microalbumin with the dry chemistry method and the im-mune quantitation method (P<0.01) The sensitivity, accuracy and Youden index of the microalbu-minuria testing had been observed to decrease in order in immune the dry chemistry method, the im-mune quantitation method and M/C quantitation detection method. Conclusion The sensitivity of semi-quantitation dry chemical method is satisfactory in detecting microalbumin, which may be used as a means of microalbumin screening. M/C detection with the dry chemical method isn't suitable for screening microalbumin in instant urine samples.

Objective Taken examination of patients with colon polyps by using narrow-band imaging (NBI) com-bined with magnified endoscope, to compare the difference in the opening of the gland morphology and pathological type. Methods 110 patients of colon polyps with 147 pathological histology biopsy samples collected. Using NBI combined with magnified endoscope techniques observe pit patterns and capillary patterns identify adenomatous polyps, and compared with the results of pathological histology, then analyze the adenomatous polyp diagnosis coin-cidence rate, sensitivity and specificity. Results The pit patterns of adenomatous polyps were mostly type Ⅲ, Ⅳ andⅤ. The diagnostic coincidence rate, sensitivity and specificity was 91.16%, 88.37%, 95.08%of adenomatous polyps. It was higher than ordinary colonoscopy (80.27%, 79.07%, 81.97%), and the diagnosis accuracy of intraepithelial neoplasia and early carcinoma of NBI combined with magnified endoscope was obviously higher than that by ordi-nary endoscopy examination, the differences were statistically significant. Conclusions NBI combined with magnified endoscope was superior in observing the opening of pit patterns and capillary patterns, which was helpful to diagno-sis of tumor lesions of colon polyps.

OBJECTIVE:To observe the influence of Valsartan on the serum ET,CGRP levels,urinary protein and Q - Td of patients with CRF complicating hypertension.METHODS: CRF research group including 24 patients with CRF complicating hypertension receiving Valsartan 80mg/ d for 4 weeks; CRF control groups including 20 CRF patients with normal blood pressure; health group including 9 health people.The serum ET and CGRP levels, urinary protein, and Q - Td were measured.RESULTS: (l)The serum ET level of CRF patients was higher than that of health people;The serum ET level of CRF research group(before treatment) was higher than that of CRF control group and decreased after treatment of Valsartan.(2) The serum CGRP level of CRF patients was higher than that of health people .The serum of CGRP level of CRF research group (before treatment) was higher than that of CRF control group and continued to increase after treatment of Valsartan. (3) The content of urinary protein of CRF patients was significantly higher than that of health people.The content of urinary protien of CRF research group before treatment was higher than that of CRF control group and decreased after treatment of Valsartan. (4) The Q - Td of CRF research group was longer than that of health group and CRF control group.But the Q - Td of CRF research group did not change after treatment of Valsartan.CONCLUSION: Valsartan could effectively control blood pressure and decrease content of urinary protein, and delay the deterioration of renal function, but could not reverse the cardiovascular remoulding.

ObjectiveTo investigate the effects of alpha-lipoic acid on serum soluble intercellular adhesion molecule-1 (sICAM-1) and high sensitive-C reactive protein (hs-CRP) levels in patients with early diabetic nephropathy (DN).MethodsA total of 61 patients with early DN were randomized into treatment group (n =31 ) and control group ( n =30 ).The two groups were both treated with dietary control and oral hypoglycemic drugs or insulin.Meanwhile,the treatment group was additionally given alpha-lipoic acid 300 mg/d by intravenous infusion for 20 days.The levels of sICAM-1 and hs-CRP in each group were detected.Results The levels of sICAM-1 and hs-CRP were decreased significantly in alpha-lipoic acid treatment group after 20 days of therapy ( [ 198.03 ±23.67] μg/L vs [271.17 ±34.66] μg/L,[5.16 ±0.43] mg/Lvs [7.95 ±0.88]mg/L,P ＜0.01 ).Conclusion alpha-lipoic acid may decrease the expression of slCAM-1 and hs-CRP,and that may be one of the mechanisms to postpone the progress of early DN.
