Objective:Analysis of two ethnic Uygur and Han investigate ischemic stroke adiponectin (Adiponectin) gene single nucleotide rs182052 , rs6444175 , rs1501296 allele polymorphism point whether the differences.Methods:Gene sequencing methods were used to detect 210 was used cases of acute ischemic stroke patients ( case group ) and 104 healthy people ( control group ) Adiponectin gene ,using case-control association analysis of genotype and allele frequencies compared explore the two ethnic differences in different gene polymorphism loci.Results: When the case group and the control group were compared , it was found that the Adiponectin gene rs64441759G/A was significantly higher in the case group.The risk rate increased significantly to 1.481 times (OR=1.481;95%CI:1.219-1.910; P=0.000).Conclusion: Adiponectin gene rs6444175A allele may be susceptible to pathogenic gene.No significant differences show on the 3 SNP loci of Adiponectin genes between Uygur and Han patients.

Objective To discuss the diagnosis and treatment of acquired cystic kidney disease complicated by kidney cancer. Methods Clinical data of 11 patients with acquired cystic kidney disease complicated by kidney cancer were analyzed retrospectively. Eight patients were male and three were female. The mean age was 55 years old (range 37 to 68). The time of hemodialysis ranged from 2.8 to 7. 4 years, mean 4. 8 years. Results Follow-up ranged from 17- 83 months, mean 55 months. One patient died of cardiovascular disease. Lung metastasis was detected in one patient two years after surgery. Seven patients survived free of tumor recurrence and there was no follow-up on one patient. Conclusions Increased incidence of cancer was observed in patients with end-stage renal disease who have undergone long-term dialysis. In particular, renal cell carcinoma (RCC) showed an excess incidence in ACKD patients. RCC showed an increased prevalence compared with the general population. Patients with predialysis azotemia or a dialysis duration of longer than 3 years should be screened for ACKD. Sonegraphy or CT scanning are useful for early diagnosis of ACKD. We should pay close attention to complications, including ACKD malignant tendency, in patients who have been taking long-term dialysis and positive therapy.

Eighty six patients with renal masses≤4.0 cm underwent ultrasound or CT-guided core needle biopsies.The clinical data including the initial biopsy technique,pathologic findings,and the clinical outcome were retrospectively reviewed. Biopsies were failed for diagnosis in 6 cases ( 7% ) because of necrosis or hemorrhage of the tissue specimens.Of 80 successful biopsies,52 cases (65%) were diagnosed as malignant tumor and 28 cases (35%) as benign. Five patients had biopsy complications (6%),including postoperative hypotension,hemouria and perirenal hematoma. Forty-seven patients underwent surgical extirpation ; the consistency rate of histopathological diagnosis between biopsy and surgical specimens was 100% in these patients.The results indicate that ultrasound or CT-guided core needle biopsy is an effective and safe procedure for diagnosis of renal small masses.

Objective To investigate the correlations of extracellular matrix and hepatic ultramicrostructural changes with clinical manifestations in patients with mild chronic hepatitis B (CHB).Methods Patients with chronic HBV infections were enrolled and were divided into mild CHB group (n=66) and HBV carrier group (n=10).Serum samples were collected from patients, and serum HBV markers, HBV DNA load and liver fibrosis indexes were measured.All subjects received liver biopsy, and the tissue samples were observed by light microscope and electron microscope.T test and χ2 test were performed for measurement data and enumeration data, respectively.Spearman test was used for ranked data.Results The differences on ALT and AST levels between mild CHB group and HBV carrier group were significant (t=12.42, 7.06, P<0.05), but there was no significant difference on HBV DNA load between two groups (t=0.24, P > 0.05).Serum liver fibrosis indexes (hyaluronic acid, type Ⅲ collagen,type Ⅳ collagen and laminin protein) in mild CHB group were not significantly higher than those in HBV carrier group (t=0.45, 0.95, 0.76 and 1.21, P >0.05).In mild CHB group, there were 33 patients with ≥G2 and ≥S2, but in HBV carrier group were only 2 patients (χ2=4.17, P < 0.05).Seventeen patients in mild CHB group were with S3-4, while that was not observed in HBV carrier group (χ2=4.75, P <0.05).In mild CHB group, hepatic ultramicrostrutural changes on fat storing cell, collagen protein and portal area were correlated with fibrosis grades, and the correlation coefficients were 0.351, 0.675 and 0.301, respectively (P=0.004, 0.000 and 0.014).Conclusion Electron microscope is of higher sensitivity than light microscope in observing hepatic ultramicrostructural changes, which is effective in evaluating the severity of mild CHB.
