Objective To study the effect of allicin on the growth and radiosensitivity of human pancreatic carcinoma BXPC3 cells.Methods BXPC3 cells were exposed to X-rays in the presence or absence of allicin.Cell proliferation was measured by MTT assay.Cell cycle distribution and apoptosis were detected by flow cytometry assay.Cell radiosensitivity and the influence of allicin on it was evaluated by colony formation assay.The expressions of Bax and Bcl-2 proteins were assayed by RT-PCR and Western blot.Results IC50 values of allicin on cell growth were 76.24,58.34 and 43.58 μmol/L under 12,24 and 48 h treatment,respectively.Treatment of cells with allicin obviously inhibited cell growth after irradiation and hence increased radiosensitivity (t =2.74,P < 0.05).This treament also enhanced radiation-induced cell cycle arrest at G2/M phase (t =11.41,P <0.05),apoptosis induction (t =12.36,P < 0.05),and Bax expression (t =4.83,P < 0.05),but it decreased Bcl-2 expression (t =3.69,P < 0.05).Conclusions Allicin could inhibit cell growth,induce cell cycle arrest and apoptosis via Bax/Bcl-2 pathway and hence increases radiosensitivity of BXPC3 cells.

Objective To evaluate the effects of low blood sugar production index (LGI) combined with low blood sugar production burden (LGL) dietary intervention on blood glucose, oxidative stress and anthropometric indicators in type 2 diabetes mellitus. Methods A total of 150 cases of type 2 diabetes were randomly divided into two groups,maintain the original treatment plan of two groups,75 patients in the control group were given traditional food interchange method for dietary intervention;the experimental group of 75 patients, provide food education based on LGI+LGI food exchange method , the time period of 3 months. Fasting blood glucose (FPG)、2h postprandial blood glucose (2hPG), Glycated hemoglobin (HbAlc), Superoxide dismutase (SOD), Malondialdehyde (MDA), Vitamin C, Vitamin E, Body Mass Index (BMI), Waist circumference (WC) Upper arm muscle circumference (AMC), Triceps skin fold thickness (TSF) were observed before and after the intervention. Results There were no significant differences in blood glucose, oxidative stress and anthropometry between the two groups (P>0.05). After intervention, in the control group: FPG, 2hPG, HbAlc, SOD, MDA, Vitamin C, Vitamin E, BMI, WC, AMC, TSF were (10.27 ± 2.67) mmol/L, (11.51 ± 2.54) mmol/L, (8.78 ± 1.95)%, (322.73 ± 51.97) kU/L, (5.80 ± 1.76)μmol/L, (40.78±4.86)μmol/L, (19.33±4.79)μmol/L, (23.94±3.18) kg/m2, (89.57±10.23) cm, (24.10± 3.01) cm, (18.38 ± 3.79)mm respectively. In the experimental group: they were (8.76 ± 2.77) mmol/L, (10.63 ± 1.76) mmol/L, (7.96 ± 1.86)%, (357.29 ± 60.04) kU/L, (5.26 ± 1.33)μmol/L, (44.01 ± 7.06)μmol/L, (21.58 ± 5.25) μmol/L, (22.93 ± 2.75) kg/m2, (86.05 ± 10.79) cm, (22.75 ± 2.86) cm, (16.98 ± 4.48) mm respectively. There was significant difference between the two groups after intervention (t=2.049-3.769, all P < 0.05). In the experimental group, the improvement of blood sugar, oxidative stress and anthropometry was better than that of the control group (P < 0.05). Conclusions LGI combined with LGL diet intervention is better than the traditional method of food interchange, the blood glucose, oxidative stress and anthropometric indicators have improved, which can improve treatment efficacy in type 2 diabetes and easy for home self-management.

Long non-coding RNA (lncRNA) is a class of RNA molecules, transcripted by RNA polymeraseⅡ, which consists of more than 200 nucleotides and protein-coding function. Many studies have indicated that lncRNA plays an important role in epigenetics, transcription and post-translational processing. The abnormal expression of lncRNA significantly correlates with occurence,development, and metastasis of renal cell carcinoma (RCC) and prognosis of the patients with RCC. This paper summarizes the advances in the research on lncRNA in RCC to reveal the mechanisms of the disease at the molecular level, in order to provide new methods of prevention, diagnosis, treatment and prognostic assessment of RCC.

Objective To investigate the mechanism and prevention of gallstones after esophageal cancer surgery.Methods Clinical data from 297 cases of esophageal cancer patients underwent surgical treatment from 2007 to 2010 inour hospital were retrospectively analyzed for the incidence of post-operative gallstones.ResultsNo cholecystitis and gallstones were detected by B-ultrosound before the operation in the 39 patients.13.1% of the patients developed gallstones from 1 month to 3 years after the operation.The incidence was significantly higher than that in general population.Conclusion There is a high chance of gallstones in patients after radical resection of esophageal cancer.Cutting vagus nerve plays an important role in the incidence of gallstones.Preservation of vagus nerve during the surgery should be performed as possible.

Objective To evaluate the differences of clinical features,neuroimaging,angiography and laboratory findings between different stroke subtypes according to TOAST criteria in elderly patients.Methods 91 patients (aged ≥ 80 years) with acute ischemic stroke were retrospectively reviewed in Departement of Neurology from April 2009 to August 2010.Subtypes of ischemic stroke were analyzed according to the classification of TOAST.Risk factors,clinical manifestations,complications,prognosis,neuroimaging,cerebrovascular lesions,and laboratory findings of different TOAST subtypes were compared.Results Large-artery atherosclerosis (LAA) (34/91) was the most common cause of acute ischemic stroke in elderly patients,and most criminal lesions (25/34) located at the intracranial arteries.In the LAA group,patients with intracranial (25/34) or extracranial (12/34) occlusive diseases were more than those in other groups.Patients with cardioembolism (CE) had lower lipid levels.In the CE group,patients with poor shortterm prognosis (7/15) were more than in the LAA or small-artery occlusion (SAO) group,and patients with severe cerebral edema (4/15) were more than those in other groups.In patients of the SAO group,complications occurred infrequently (4/20),and none had poor short-term prognosis.Conclusions There were some differences among different TOAST subtypes in clinical features,neuroimaging,cerebrovascular diseases,and laboratory findings.The clinical significance of our findings needs to be explored further.
