Objective To study the effects of XiaoAiping (XAP) with different concentrations and action time on the proliferation and apoptosis of hepatocellular carcinoma cells Hepa1-6. Methods The hepatocellular carcinoma cell line Hepal-6 was treated with XAP at doses of 30 mg/ml(the high concentration group), 20 mg/ml (the moderate concentration group) and 10 mg/ml (the low concentration group) for 24 h, 48 h and 72 h, respectively. The MTT assay was used to detect the inhibitory effects of XAP on cell growth. The cell morphological alteration was observed after HE staining, and the apoptosis rates were assayed by flow cytometry. Results XAP produced an obvious time-and-dose-dependent inhibitory effect on the Hepa1-6 cells (P<0.01), and the cell differentiation trend was benign on light microscopy. After 48 h Hepa1-6 cells were incubated by XAP, there was an apoptosis peak, and the apoptosis rate was increased statistically in XAP group with the increasing XAP concentration [(7.65±0.40)%, (11.26±1.09)% and (26.71±0.85)% in low, moderate and high concentration group, respectively]compared with that in the controls (2.88 ±0.30)%, P < 0.01). Conclusion XAP produced obvious time-and-dose-dependent inhibitory effects on Hepa1-6 cells. Inhibiting DNA synthesize and inducing apoptosis of tumor cells may involve in the mechanisms of antineoplastic effect.

Background:Chronic constipation is a major cause of impaired quality of life in modern society. Reasonable and effective management of chronic constipation could be achieved based on the principle of evidence-based medicine and the modern concept of constipation,and this is a challenge facing the clinicians. Aims:To investigate the role of barium-based colonic transit detection in diagnosis and treatment of chronic constipation. Methods:Fifty patients with chronic constipation from Apr. 2013 to Oct. 2014 at the First Hospital of Shanxi Medical University were recruited and randomly allocated into two groups,control group and individualized treatment group. Patients in individualized treatment group received 20 barium markers orally and abdominal plain radiography was performed 48 and 72 hours later,respectively for calculating the colonic transit index. According to the type of colonic transition and the characteristics of colonic motility estimated by colonic transit index and clinical manifestations,an individualized therapeutic regimen was formulated and the efficacy was evaluated. Patients in control group were treated empirically according to the clinical manifestations. Results:Mosapride and lactulose or polyethylene glycol were administered orally in control group;when abdominal pain or abdominal distension was predominant,pinaverium bromide or trimebutine was used respectively instead of mosapride. Barium-based colonic transit detection revealed that 9 patients in individualized treatment group were slow transit constipation,6 were outlet obstructive constipation and 8 were the mixed type. After 2 weeks of empirical or individualized treatment,the defecation rates of the two groups were 24. 0%(6 / 25)and 52. 2%(12 / 23)within 24 hours and 64. 0%(16 / 25)and 87. 0%(20 / 23)within 48 hours,respectively(P all < 0. 05). Conclusions:Barium-based colonic transit detection is a simple,economical and practical modality for guiding the individualized treatment in patients with chronic constipation.
