AIM: To study the effects of astragalosides (AS) on the proliferation and cell cycle of rat glomerular mesangial cell (MC), and verify the correlation between the influence and the AS concentration. METHODS: The experiment was carried out in the Physiological Laboratory of Liaoning Medical University from December 2006 to July 2007. Rat glomerular MCs were cultured in high glucose for 4-7 passages. The experiments were randomly divided into control group and three AS groups with different concentrations (50, 100, 200 mg/L), which were treated with high-glucose liquid and AS respectively. MC proliferation was determined with MTT colorimetric method in each group at hours 48 after intervention. MC cell cycle was detected with flow cytometry. RESULTS: ①MTT results showed that, the values of A490 nm in AS groups were lower than that in the control group at hours 48 (P

Objective:To explore the risk factors influencing the prognosis for patients with hepatocellular carcinoma (HCC) recurrence after liver transplantation and summarize the relevant diagnostic and therapeutic experiences.Methods:The clinicopathological features with diagnosis and treatment plan of 102 recurrent HCC patients fulfilling the Fudan Criteria were compared for survival rate (univariate analysis) and independent prognostic indicators were obtained by Cox multivariate analysis.Results:The 1/3/5-year overall survival rates were 92.2%, 48.6% and 34.6% and the 1/3/5-year survival rates with tumor were 63.2%, 31.0% and 16.7% respectively. Cox regression analysis indicated that patient age, whether tumor can be surgically resected or not and personalized diagnostic & therapeutic plan based upon targeted therapy were independent prognostic factors affecting the overall survival rates and survival rates with tumor.Conclusions:Although HCC recurrence and metastasis after liver transplantation seriously influence patient prognosis, satisfactory outcomes may be obtained for some patients through active, effective and precise managements.

Objective To explore the influence of interleukin-2 receptor antagonists(IL-2Ra) on the morbidity and prognosis of new onset diabetes after transplantation(NODAT)in liver transplant recipients. Methods Pre-and post-operative clinical data of 879 nondiabetic patients who underwent a liver transplantation between April 2001 and December 2016 were retrospectively studied. All the enrolled patients were divided into IL-2Ra and non-IL-2Ra groups according to the use of IL-2Ra. Transient-NODAT(T-NODAT)and Persistent-NODAT(P-NODAT)were defined according to whether NODAT would be existed continuously. The impacts of IL-2Ra on the cumulative incidence as well as the risk of NODAT and T-NODAT were analyzed through comparison between patients who used IL-2Ra or not. And influence of IL-2Ra on the long-term survival of NODAT patients was further analyzed. Results Among 879 patients,177(32.24%)from the IL-2Ra group(n=549)developed NODAT and 29.38%(n=52)of the NODAT reversed,while 131(39.70%)from the non-IL-2Ra group(n=330)developed NODAT and 26.72%(n=35)of the NODAT reversed. After adjusting for 18 possible confounding factors,the IL-2Ra group had significantly decreased cumulative incidence of NODAT over the non-IL-2Ra group(adjusted P=0.028). COX regression analyses showed that IL-2Ra was a protective factor against NODAT development(HR 0.774;95% CI 0.616-0.973; P=0.028), while the use of IL-2Ra and the reverse of NODAT did not significantly related. In addition, long-term survival of the NODAT patients were far better in the IL-2Ra group(adjusted P=0.001). Conclusion IL-2Ra significantly reduces the risk of NODAT in liver transplant recipients and is beneficial to the long-term survival of NODAT patients.
