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.

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 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.

Objective:To explore the resource of rice bran by comparing antioxidative activities and growth promotion of Bacillus bifidus between supernatant of formented rice bran(RBF) by Bacillus natto and water extract of rice bran(RBW) . Method:The reducing capacity the?OH and ??O 2 scavenging capacity and the inhibitory effect to oxidize lard were determined in vitro. The growth promotion for Bacillus bifidus by photodensity with simulated condition was investigated in vivo. Results:RBF and RBW had antioxidant activity in vitro. The IC50 of scavenging?OH and ??O 250 of RBF was 3.55 mg/ml and 23.5 mg/ml,0.3 and 10 folds higher than that of RBW respectively. In inhibiting oxidation of lard,RBF had a little higher antioxidative activities than RBW,near VE. RBF and RBW could promot growth of Bacillus bifidus by 65.2% and 17.8% respectively. By enzymatic digestion,the promotive rate of RBF was still 51.6%. Conclusion:RBF had higher antioxidant activity and growth promotion to Bacillus bifidus.

Objective To evaluated the clinical outcomes of intravesical instillation resiniferatoxin(RTX) for the treatment of patients with idiopathic overactive bladder(IOAB).Methods 26 cases with IOAB were randomly divided into test(A,14 cases) and control(B,12 cases) groups.The patients in group A were treated by intravesical instillation with 40ml of 0.5% idocain retained within the bladder for 3 minutes at first and with 100ml of 100nmol/L RTX retained within the bladder for 30 minutes late.The patients in group B were treated by the same method,however,the furacilin solution(placebo) at a dilution 1∶5000 was used instead of 100nmol/L RTX.The efficacy(daily voiding frequency,urgent uresis,FDV,MCBC,Qmax) of the 2 groups were evaluated before,1 month and 3 months after treatment.Results The pre-treatment comparion with prost-treatmen at 1 month and 3 months of A group was significant(P0.05).14 patients(54%) had slightly stimulating symptom in the urethra or bladder,and were otherwise generally well tolerated.Conclusion Single administration of RTX is safe and effective in patients with IOAB.
