Objective To observe the protective effects of FTY720 on the Con A-induced mouse hepatic fibrosis injury,and to find the possible mechanisms of protective effects.Methods The pathologic models of hepatic fibrosis injury in the mice caused by Con A were set up.Forty mice were randomly divided into control group, model group,high dose of FTY720 (4 mg·kg-1 )group and low dose of FTY720 (1 mg·kg-1 )dose group (n=10).The serum alanine aminotransferase (ALT)and asparate aminotransferase (AST)activities,hepatic index and pathological changes of hepatic tissue were detected .Results Compared with model group,the serum ALT and AST activities in low and high doses of FTY720 groups were decreased significantly (P < 0.05 or P < 0.01).The optical microscope results showed that there were inflammatory cells and hepatocellular necrosis in model group. The masson staining results showed that there were surrounding fiber bundle and hepatic lobule fusion in model group;compared with model group,the damage degree in low and high doses of FTY720 groups was reduced.The protective effects of FTY720 on hepatic injury showed linear relation to the drug dose.Conclusion FTY720 could decrease the levels of ALT/AST,thus FTY720 alleviate hepatic damage degree and delay the process of hepatic fibrosis.The protective effects of FTY720 on hepatic injury in experimental hepatic fibrosis mice may be related to the mechanisms mentioned above.

OBJECTIVE: To investigate the clinical features and therapeutic effects of sudden deafness after radiotherapy combined with chemotherapy in nasopharyngeal carcinoma patients. METHOD: Clinical data of 42 nasopharyngeal carcinoma patients suffered from sudden deafness after radiotherapy combined with chemotherapy were analyzed retrospectively. Among the 42 patients, 2 showed moderate deafness, 4 presented excessive deafness, 30 suffered from severe deafness, and 6 exhibited profound deafness. The audiogram pattern of 33 patients met with the type of high tone frequencies hearing loss, and that of the rest 9 cases showed hearing loss at all frequencies. All patients received medical therapy combined with hyperbaric oxygen therapy. RESULT: Of all the cases with hearing loss, 2 were cured, 2 showed excellent recovery, 9 came out partial recovery, and 29 showed no response to the treatment. The total effective rate was 30.95%. For the accompanied symptoms, none of the 30 cases of tinnitus were relieved, 3 out of 10 cases of aural fullness were cured, and the 5 cases of dizziness or vertigo were all improved. CONCLUSION The sudden deafness after radiotherapy combined with chemotherapy in patients with nasopharyngeal carcinoma is closely related to radiotherapy. The hearing loss is serious, and the therapeutic effects are not satisfactory.

Objective To explore the clinical efficacy of Shenkang Injection and its influence on C-reactive protein (CRP)and interleukin-6 (IL-6)levels in patients with diabetic nephropathy (DN).Methods A total of 120 patients with type 2 diabetes mellitus combined with DN admitted in our hospital from Jan.2012 to Jan.2014 were randomly divided into observation group and con-trol group,60 cases for each.Control group was treated with high-quality protein diets and insulin to control blood glucose and pressure,on which basis observation group was added with intravenous injection of Shenkang Injection.Clinical efficacy,fasting blood glucose (FBG),Triglyceride (TG), total cholesterol (TC),serum creatinine (SCr),24 h urinary protein (24 hUpro),CRP and IL-6 level changes before and after treatment in both groups were observed.Results Clinical efficacy was 90.00% in observation group,evidently higher than 75.00% in control group (P <0.05). Aboveindexeswere all improvedobviously after treatment than treatment before (P < 0 .0 5 ,P <0.01)and were markedly lower in observation group than in control group (P <0.01).Conclusion Shenkang Injection can effectively reduce IL-6 and CRP levels and decrease blood glucose and pressure,prolong disease progression and improve prognosis in DN patients.

Objective:To explore the clinical value of recurrent laryngeal nerve dissection in the surgical treatment for congenital pyriform sinus fistula（CPSF）. Methods:The clinical data of 42 patients with CPSF were retrospectively analyzed. All patients were diagnosed and treated in the First Affiliated Hospital of Guangdong Pharmaceutical University. Results:During the operation, all patients' recurrent laryngeal nerves were dissected successfully, and fistulas were resected completely,no patients had complication of recurrent laryngeal nerve's damage.There were no recurrence cases during the 13 to 48 months of follow-up. Conclusion:The trend of congenital pyriform sinus fistula is closely related to recurrent laryngeal nerve, it's important to dissect the recurrent laryngeal nerve during the operation for congenital pyriform sinus fistula.
