Objective To investigate the clinical and pathological features of elderly patients with hepatocellular carcinoma (HCC)and the prognosis after radical resection.Methods From January 2013 to December 2014,98 elderly patients with primary liver cancer were enrolled in this study,with 120 non-elderly patients with primary liver cancer serving as the control group.Comparison was made concerning clinical and pathological characteristics,short term postoperative outcomes and long-term prognosis between the two groups.Results The average age of patients in the elderly group(68.4±3.7)was significantly higher than in the control group(53.6 ±5.3),and the difference was statistically significant(t=23.376,P＜0.001).The positive rate of HBsAg in the elderly group was 38.8 ％,higher than in the control group (70.0 ％),and the difference was statistically significant (x2 =21.341,P＜0.001).The incidence of liver failure in the elderly group was 4.1％,higher than in the control group (0.0 ％),and the difference was statistically significant (xe =4.990,P =0.026).There was no significant difference in survival rate at 6 months,1 year and 2 years between two groups (x2 1.427,2.127,and 0.510,each P＞0.05).There was no significant difference in recurrence rate between the two groups at 1 year and 2 years(x2 =0.205 and 0.706,each P＞0.05).Conclusions Elderly patients with hepatocellular carcinoma present favorable clinical and pathological features and show similar short and long-term outcomes,compared with non-elderly patients.Radical resection is valuable in the treatment of hepatocellular carcinoma in elderly patients.

HPLC analysis was performed to study the changes in chemical composition of ginseng extracts prepared from high quality ginseng with 0, 2, 4, 8 h of steamed times. An UFLC-MS/MS multiple-reaction monitoring (MRM) quantitative analysis was made to investigate the pharmacokinetic behavior differences of ginsenosides in mice ig administered of ginseng extracts with different steamed times in the negative ion mode, with Digoxin as the internal standard substance. The mice were injected with LPS to establish inflammation model after ig administration of ginseng for a week and the contents of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in mice plasma were detected by ELISA, in order to study on anti-inflammatory effects of ginseng with different steamed times. It was determined that levels of TNF-α and IL-1β were significantly decreased in inflammation model group ig administered of ginseng extracts with 8h of steamed time. The results showed that the chemical components in ginseng changed after steaming and the components into the blood changed, correspondingly. Ginseng with steamed 8 h contributes to anti-inflammatory effects. These results provided an experimental basis for revealing the active substance basis and dose-effect relationship of ginseng on anti-inflammatory effect.

OBJECTIVETo evaluate the clinical efficacy and safety of phosphodiesterase 5 (PDE-5) inhibitors for erectile dysfunction (ED) in patients with diabetes mellitus and provide some evidence for the clinical treatment of the disease.

METHODSWe searched MedMed, EMbase, Cochrane Library, CNKI, Wan Fang Data, VIP and ZADL for randomized controlled trials on PDE-5 inhibitors for ED in diabetic men and evaluated the methodology of the included trials with the Jadad scale. We used the erectile function domain in the IIEF (IIEF-EF), IIEF questions (IIEF-Q) 3 and 4, SEP-2 and -3, and Global Assessment Questions (GAQ) as the main evaluation indexes and employed the Review Manager 5. 1. 0 software for meta analysis.

RESULTSA total of 13 studies were included, which were all high quality trials with Jadad score > 3. The IIEF-EF scores in 10 of the included studies were subjected to meta analysis using the random-effect model (REM), with a weighted mean difference (WMD) of 5.64 (95% CI 4.41 - 6.83, P < 0.001). The fixed-effect model (FEM) analysis of the IIEF-Q scores in 6 of the studies showed the WMD to be 0.96 (95% CI 0.83 -1.08, P < 0.001) for IIEF-Q3 and 1.11 (95% CI 0.98 - 1.25, P < 0.001) for IIEF-Q4. FEM analysis of the SEP-2 scores showed WMD = 17.67 (95% CI 12. 38 - 22. 97, P < 0.001) in 2 of the studies, and that of the SEP-3 scores WMD = 23.64 (95% CI 17. 49 - 29.79, P < 0.001) in 5 of the studies. The GAQ scores in 11 of the studies were subjected to REM analysis, with OR = 6. 20 and 95% CI 3.65 - 10.52 (P < 0.001). REM analysis was performed on the adverse reactions in 11 of the studies, with OR = 7.43 and 95% CI 4.11 - 13.44 (P < 0.001).

CONCLUSIONPDE-5 inhibitors can effectively and safely improve erectile function in patients with diabetes mellitus.

To compare the difference of total phenol of magnolia solid dispersion prepared by different methods. Hot melt extrusion, solvent evaporation method, and fusion-cooling method were used to prepare total phenol of Magnolia accessory solid dispersion, Plastone S-630 and HPC. The drug dispersion state in the prepared solid dispersion was evaluated with DSC and X-ray diffraction; FT-IR method was used to analyze the possible connections between drug and accessories. Finally, accelerated stability-in vivo dissolution test was use to compare the stability differences between these three processes. The results of DSC and X-ray diffraction showed that all of the drug in solid dispersion processed by three processes can exist in amorphous form; FT-IR results also could not distinguish the difference between the three processes; accelerated stability-in vivo dissolution test showed the stability of solid dispersion prepared by HPC was better than Plastone S-630, and the same kinds of materials solid dispersion prepared by hot melt extrusion showed a better stability than the other two processes.
