Objective In order to improve the diagnosis accuracy , 18F-FDG PET/CT results of 169 cases of lung lesions were analyzed. Methods The data of 169 pathological diagnosed patients were collected. SPSS 18.0 was used for the data analysis. Results In 169 cases, 122 cases were proved malignant by patholog-ical diagnosis, in which 110 cases were correctly diagnosed by PET/CT. 47 cases were proved benign by patho-logical diagnosis, in which 15 cases were correctly diagnosed by PET/CT. The sensitivity was 90.2%, specificity was 31.9%, and the accuracy was 74.0%. Conclusion In order to improve the accuracy rate of PET/CT exam-ination and reduce the existence of false positive cases and false positive cases , we should estimate SUV (max) objectively and diagnose according to the size of the lesion , clinical history and laboratory results.

Objective To explore any correlation between gait asymmetry and the balance of hemiplegic stroke survivors.Methods Thirty patients with hemiplegia caused by stroke but who could walk more than 10 metres independently were recruited as the experimental group; 30 age-matched healthy elderly people served as the control group.An AL-600 gait analyzer was used to quantify the spatial and temporal gait parameters of all subjects.Gait asymmetry ratios were calculated.The 30 stroke patients were also assessed with the Berg balance scale (BBS).Two independent sample t-tests were used to compare the step length asymmetry (SLA),swing time asymmetry (SWTA) and STA (stance time asymmetry) ratios for the two groups and their average step widths.Pearson correlation coefficients were calculated relating the SLA,SWTA,STA,step width and BBS results.Results Among the experimental group,swing time and step length on the affected side were significantly different from the unaffected side,and stance time on the affected side was significantly shorter.The control group showed no such significant differences.All of the experimental group's average asymmetry ratios were significantly greater than those of the control group,as was their step width.Step width and BBS score were negative correlated,but step width was positively correlated with the step length and swing time asymmetry ratios.BBS scores were negatively correlated with the step length and swing time asymmetry ratios.Stance time asymmetry and step width showed no significant correlation with the BBS scores.Conclusion The gait of hemiplegic stroke patients is both spatially and temporally asymmetric,and a certain correlation exists between the degree of asymmetry and balance function.

Objective:To investigate the expression of sal-like 4 (SALL4) gene in children with acute leukemia and analyze its clinical significance. Methods:Real-time PCR and immunohistochemistry were used to detect SALL4 mRNA and SALL4 protein ex-pressions in 50 patients initially diagnosed with acute leukemia and in 15 patients with immune thrombocytopenic purpura (ITP), which served as controls. Changes were detected in SALL4 mRNA expression from preliminary diagnosis and after complete remission of 5 acute leukemia patients. The relationship between SALL4 mRNA expression and clinical indicators was analyzed. Results: SALL4 mRNA expression is higher in initially diagnosed B-ALL [13.89 (1.00-63.15)] and AML [11.12 (2.31-56.59)] than in ITP controls [1.00 (0.29-1.71)] (P<0.01). SALL4 mRNA expression in initially diagnosed T-ALL [1.48 (0.87-4.81)] and in controls showed no significant difference (P>0.05). SALL4 protein expression is in agreement with SALL4 mRNA expression. SALL4 mRNA expression significant-ly decreased in complete remission stage [0.98 (0.22-1.09)] than in acute phase [28.64 (11.20-87.46)] in acute-leukemia patients (P<0.01). High SALL4 mRNA expression level is positively correlated with high white blood cell count, high risk classification, and high minimal-residual disease at the end of induction chemotherapy (r=0.424, r=0.40, and r=0.393, respectively;P<0.05), but not with age, gender, hepatomegaly, splenomegaly, and lymphadenectasis (P>0.05). Conclusion:SALL4 was found to play an important role in pro-moting childhood B-ALL and AML, which promises a new target for monitoring the therapeutic effects and evaluating the prognosis of childhood B-ALL and AML.

Objective To develop a model of type 2 diabetes with early renal injury on spontaneously hypertensive rats (SHR). Methods The 6-week old SHR were fed with the diets enriched with sucrose (20%, W/W), lard (10%, W/W), cholesterol (2.5%, W/W) and chleolate (1%, W/W) to induce insulin resistance. Hyperglycemia was developed by intraperitoneal injection of streptozotocin (STZ, 35 mg/kg). Wistar-Kyoto rats (WKY) were used as normal controls. Rats with plasma glucose (PGL) ≥ 16.7 mmol/L were diagnosed as diabetes. Eight weeks after the induction of diabetes, plasma triglyceride (TG), cholesterol (CHO), glucose, systolic pressure(SP), 24-h urine protein excretion (Upro) were examined in all the rats, and the homeostasis model assessment of insulin resistance (HOMA-IR) was analyzed. Renal pathological changes were studied by immunohistochemical staining and electron microscope. Results After 2 weeks on the high sucrose and fat diets, the model rats exhibited significant increase in basal PGL, TG and CHO levels as compared to control rats (P<0.05, respectively). The insulin resistance was developed in model rats demonstrated by the higher HOMA-IR (5.03±0.38 vs 2.61±0.34, P<0.05). At the end of the experiment, model rats were associated with hypertension. Upro level was significantly increased in model rats compared with that in controls [(57.58±16.54) mg/24 h vs (5.35±1.90) mg/24 h, P<0.01]. The kidney hypertrophy index (KWI) was significantly increased in the model rats compared to controls (P <0.05). Moreover, the diabetic model rats showed glomerular hypertrophy, foot process effacement, micro villous transformation, glomerular basement membrane (GBM) thickening. Conclusion A rat model is successfully established, which presents typical features of human type 2 diabetes and can be served as an ideal model to study the diabetic nephropathy.
