Aim To investigate the effects of allicin on the proliferation and apoptosis of HL-60 cells,and to explore the underlying mechanism.Methods The cell viability and colony formation were detected by MTT assay.Apoptotic cells were tested by means of TUNEL labeling.RT-PCR was used to analyze the bcl-2 mRNA expressions.Results HL-60 cell growth was significantly inhibited by allicin in dose and time dependent manners.Cell colony formation obviously decreased.The typical hypo-diploid pea J apoptotic peaJ appeared in each dose group.Apoptosis occured in a dose-dependent manner.And its later stages were identified by TUNEL labeling methods respectively,and bcl-2/bax was decreased.The expression of bcl-2 mRNA was down-regulated in a time-dependent manner after treatment with allicin at different time points.Conclusion Allicin effectively inhibits growth and induces apoptosis on HL-60 cells,which may be related with the down-regulation of expressions of bcl-2.

Objective: To study the effects of Ruanmailing Oral Liquid, a compound traditional Chinese herbal medicine, on spatial learning and memory ability and expression of apurinic/apyrimidinic endonuclease/redox factor-1 (APE/Ref-1) in hippocampal CA1 region in rats with experimental vascular dementia (VaD). Methods: VaD was induced in rats by permanent occlusion of bilateral common carotid arteries. Forty-five VaD rats were randomly divided into untreated group, nimodipine group, low-dose Ruanmailing group and high-dose Ruanmailing group. Another 15 rats underwent a sham operation consisting of similar skin incision and manipulation but without occlusion of carotid arteries. From the next day after occlusion, the rats were intragastrically administered with normal saline, nimodipine suspension or Ruanmailing Oral Liquid respectively for 30 days. Morris water maze experiment was adopted to test learning and memory of rats in each group. Expression of APE/Ref-1 protein in the hippocampal CA1 region was measured by immunohistochemical method. Results: Escape latency was significantly shortened and number of entries in the target area of rats was significantly increased in the high-dose Ruanmailing group as compared with those in the untreated group (P<0.01). Compared with the untreated group, count of APE/Ref-1 positive cells was significantly increased in the hippocampal CA1 region in the high- and low-dose Ruanmailing groups (P<0.01). Compared with the low-dose group and the nimodipine group, the count of APE/Ref-1 positive cells was remarkably increased in the hippocampal CA1 region in rats of the high-dose Ruanmailing group (P<0.01). There was no statistical difference between the low-dose Ruanmailing group and the nimodipine group. Conclusion: Ruanmailing Oral Liquid can improve the learning and memory ability and enhance the lowered expression level of APE/Ref-1 in the hippocampal CA1 region of rats with VaD.

OBJECTIVE: To investigate the pathological change of mice organ intoxicated by Alangium Chinese and its poisoning mechanism. METHODS: Mice were intoxicated by gavage with extract of Alangium Chinese. Then the histopathologic examination was made for evaluating the pathological changes in the organs of the poisoned mice by HE staining. RESULTS: The main pathological changes included alveolar hemorrhage, pulmonary interstitial hemorrhage, sinus hepaticus expansion and congestion, hepatocyte edema, subarachnoid hemorrhage, congestion and hemorrhage of other organs. CONCLUSION The main target organs or tissue of Alangium Chinese are the lungs, liver and vascular smooth muscle. There is correlation between the toxic effect and the dosage.

Objective:To investigate and analyze the clinical efficacy of salvage liver transplantation (SLT), rehepatectomy (RH), local ablation (LA), and prognostic risk factors in patients with postoperative recurrence of hepatocellular carcinoma.Methods:Clinical data of 145 patients with recurrent liver cancer in the 900th Hospital of the Joint Logistics Support Force of the People's Liberation Army from January 2005 to June 2018 were retrospectively collected. SLT group, RH group, and LA group included 25, 44, and 76 cases, respectively. Follow-up and statistics were recorded on the overall survival rate, relapse-free survival rate, and complications of the three groups of patients at 1, 2, and 3 years after surgery. Univariate and multivariate COX analyses were used to analyze the prognostic risk factors in patients with recurrent HCC.Results:The overall survival rates of 1, 2, and 3 years following surgery in the SLT, RH, and LA groups were 100.0%, 84.0%, 72.0%, 95.5%, 77.3%, 65.9%, 90.8%, 76.3%, and 63.2%, respectively, when the recurrence of liver cancer met the Milan criteria. The overall survival rate did not differ statistically between SLT and RH ( P = 0.303) or between RH and LA ( P = 0.152). There were statistically significant differences in recurrence-free survival between SLT and RH or RH and LA ( P = 0.046). There was no statistically significant difference in the incidence of complications between SLT and RH or RH and LA ( P > 0.017). Age > 65 years was an independent risk factor affecting the overall survival rate in patients with recurrent HCC. Age > 65 years and recurrence time < 24 months were independent risk factors affecting the recurrence-free survival rate in patients with recurrent HCC. Conclusion:SLT is the best treatment option when the recurrence of HCC meets Milan's criteria. RH and LA are the appropriate treatment plans for recurrent HCC when the liver source is limited.
