Objective To study the expression of integrin ?1 in hepatocellular carcinoma (HCC) and its significance. Methods Integrin ?1 expression was detected in 38 cases of HCC, 8 cases of hepatic cirrhosis (HC) and 7 cases of normal liver tissues(NL) using immunohistochemical SP method. The relationship between the integrin ?1 expression and HCC clinico-pathological features was analyzed. Results The positive rate of integrin ?1 expression in the HCC was much higher than that in the HC and NL tissues (P

Objective To explore the expression of tenascin in hepatocellular carcinoma (HCC). Methods With the method of immunohistochemical staining, specimens from 42 HCC patients, 10 hepatic cirrhotics and 7 normal liver controls were studied. The relationship between the tenascin expression and pathological features as well as microvessel density (MVD) was evaluated.

Objective To study the pathologic feature and rational diagnosis and treatment of Mirizzi Syndrome. Method The clinical data of 43 cases treated by surgery were retrospectively analysed. Results All the 43 cases underwent operation, including partial cholecystecomy in 8 cases, cholecystectomy in 16cases , cholecystectomy plus common bile duct exploration with T tube drainage in 9 cases, choledochojejunostomy in 10 cases. Of the 43 cases, 36 cases were followed up for 1~5 years. Of them, 29 cases were in excellent, 6 cases in good and 1 case in poor. Conclusions The pathologic type of Mirizzi Syndrome is variant. It is difficult to make a definite diagnoses before operation. So vary imaginal technique should be adopted. Different operative procedures should be used according to patients' pathologic type.

Objective To investigate the clinical imaging features and immune manifestations of clear cell carcinoma and papillary renal cell carcinoma at the same time in one side of the kidney,in order to increase the awareness of the disease and improve the clinical diagnosis and treatment.Methods This study retrospectively analyzed the clinical data of 7 patients with unilateral renal clear cell carcinoma combined with papillary cell carcinoma admitted to the Department of Urology,People's Hospital of Xinjiang Uygur Autonomous Region from January 2007 to June 2017.The general data,images performance,surgical methods,immunohistochemical results of the patients were observed.Results In 7 patients with multiple tumors of ipsilateral kidney,6 were males,accounting for 85.71% (6/7);1 female,accounting for 14.29% (1/7).Ages 45-78 years old,average 63 years old;4 cases were found by physical examination,accounting for 57.14% (4/7);2 cases were admitted to hospital with obvious oncological symptoms,accounting for 28.57% (2/7);1 case of renal nonfunction,accounting for 14.29% (1/7).The tumor was located in 6 cases of left kidney,accounting for 85.71% (6/7),and the tumor was located in 1 case of right kidney,accounting for 14.29% (1/7).Preoperative imaging examination clearly indicated multiple tumors in 3 cases,and the remaining 4 cases only showed placeholders.Lesions,of which the maximum diameter of the tumor 7.5 cm,2 patients with a diameter of > 4 cm;4 cases of radical renal resection and partial nephrectomy;3 cases of clear cell carcinoma Fuhrman Ⅰ grade,Fuhrman Ⅱ grade 5 cases postoperative pathology report There were 4 cases of papillary renal cell carcinoma in Fuhrman grade Ⅰ and 3 cases in Fuhrman grade Ⅱ,all of them were type Ⅰ cell carcinoma.Conclusions Ipsilateral kidney associated with papillary renal cell carcinoma and clear cell carcinoma is rare clinically,its formation is unknown.Readings should be repeated before surgery.If you can identify multiple tumors,you will be able to choose the surgical procedure.Partial nephrectomy or radical nephrectomy may be performed depending on the size of the tumor.Radical nephrectomy is recommended.

Summary: To investigate the difference in expression of hTERT gene between HbsAg-positive human hepatocellular carcinoma (HCC) and HbsAg-negative HCC and to explore the relationship between HBV infection and hTERT gene expression in HCC. The expression of hTERT protein in 30 cases of HbsAg positive HCC and 17 cases of HbsAg negative HCC was detected by immunohistochemistry (SP method), and the expression of hTERT mRNA was analyzed by reverse transcription polymerase chain reaction (RT-PCR). t-test, Chi-squared test and cochran- armitage trend test were used to see whether there was an interrelation between HBsAg and hTERT gene in HCC. The expression of hTERT protein was mostly located in plasm and occasionally in the nucleus of liver cancer cells. The positive rate of hTERT protein and hTERT mRNA in HbsAg positive HCC- 93.33 % (28/30) and 83.33 % (25/30) respectively which were much higher than those in HbsAg negative HCC- 52.94 % (9/17), 47.06 % (8/17) (P<0.01) respectively. HbsAg is related to hTERT gene expression in human hepatocellular carcinoma. The hTERT gene activated by the efficacious ingredient of HBV may play an important role in hepatocellular transformation and carcinogenesis.

Objective To evaluate the clinical effect of iliac artery interventional chemotherapy combination with bladder perfusion for high level of bladder urothelial carcinoma after transurethral bladder tumor electricity cut operation for those who intend to retain the bladder.Methods From February 2010 to December 2016,a total of 74 cases high-grade urothelial carcinoma of the bladder,giving chemotherapy and suitted support were retrospectively analyzed.The patients were divided into two groups according to different chemotherapy methods.Artery perfusion chemotherapy group:43 cases treated by transurethral bladder tumor cutting + bilateral iliac artery interventional perfusion chemotherapy + bladder perfusion in combination therapy;Intravenous chemotherapy group:31 cases underwent transurethral bladder tumor cut method + cisplatin,vein gemcitabine + bladder perfusion chemotherapy combined therapy.According to the ((x) ± s) between the groups.The method of count data is represented by chi-square test.Kaplan-meier method was used to describe the survival time of two groups of patients after operation.Results Two groups of patients with postoperative there was no statistically significant difference in disease-free survival time.In the bone marrow suppression (x2 =4.956,P =0.029);gastrointestinal tract reaction (x2 =5.912,P =0.012);dermatitis,mucositis (x2 =4.276,P =0.013),etc.,has the advantages in the iliac artery interventional perfusion chemotherapy (P < 0.05).Conclusion Via efficient iliac arterial infusion chemotherapy in patients with venous chemotherapy patients,to the retention of the bladder has a certain value,and the incidence of adverse reactions after surgery is low,have certain advantages.
