With the deterioration of environment, and the excessive collection of wild resources, the wild populations of Myla- bris phalerata Pallas are less and less, almost extincted in many traditional distribution areas. It is necessary to breed M. phalerata artificially for sustainable utilization. Food preference of adult M. phalerata is the key to its provenance screening and domestication in the artificial breeding. In this paper, the food preference of 3 geographical populations of M. phalerata was studied. The results showed that the food preferences of adult M. phalerata in different geographical populations were different. The adult M. phalerata in Wuming preferred cucumber flowers, gourd flowers and melon flowers. The adult M. phalerata in Tianlin preferred cowpea flowers. And the adult M. phalerata in Guangzhou preferred cowpea flowers and gourd flowers. Gourd flowers were the most attractive food for the adult M. phalerata of 3 geographical populations of M. phalerata.

Objective To investigate the effectiveness of radio gu ided surgery (RGS) in lung carcinoma by using ~18F-FDG. Methods Forty mice bearing lung adenocarcinoma were divided randomly into two gro ups according to presence or absence of the lung metastasis. A dose of 200?l (1 00?Ci) of ~18F-FDG was injected via the tail vein. The external radioimmu nography was performed after injection. All viscerae and tumor were detected i n vivo by means of a hand-held gammaray-detecting probe (GDP), and the radio active distribution was analyzed with the well-gammaray detector. Resul ts The tumor images in mice were clear, and the images were best at two hours after injection. The values of %ID/g of tumor and heart obtained by well -gammaray detector were higher than those of other organs. Ratios of tumor/norm al tissue (T/NT) except cardiac muscle being detected by GDP ranged from 3.71 t o 13.57. There was a significant difference between the radioactivity of lung t issues in lung metastasis group and that of control group (P

Objective:To investigate the differences in related indices of ulcerative colitis (UC) respectively induced by free drinking and intragastric administration of dextran sodium sulfate (DSS) in mice to provide experimental reference for the optimization of UC model.Methods:Totally 30 C57BL/6 mice were randomly divided into the normal control group,free drinking group and intragastric administration group with 10 ones in each.The mice drank water freely with free drinking or intragastric administration of 3% DSS solution at the dose of 4 g·kg-1·day-1 for 7 days to establish the UC model.The differences in disease activity index (DAI),histological damage sore and activity of myeloperoxidase (MPO) among the groups were compared.Results:Two mice died during the experiment in the free drinking group,and DAI of survival mice was (8.8±1.6).There was no death of mice in intragastric administration group,and DAI was (9.0±0.8),and there was no significant difference in DAI between the groups (P>0.05),while the coefficient of variation in the free drinking group was higher than that in the intragastric administration group (18.7 vs 8.6).The colonic histological damage score of the free drinking group and the intragastric administration group was 24.8±4.2 and 27.0±2.8,respectively,which was typical inflammatory change with no significant difference (P>0.05),while the coefficient of variation of the free drinking group was higher than that of the intragastric administration group (16.9 vs 10.4).MPO of the normal control group,free drinking group and intragastric administration group was (0.41±0.03),(2.32±0.34) and (2.05±0.18) U·g-1,respectively.Compared with the normal control group,significant difference in MPO was shown in the free drinking group and the intragastric administration group (P<0.01),while there was no significant difference in MPO between the groups (P>0.05),and the coefficient of variation in the free drinking group was higher than that in the intragastric administration group (14.7 vs 8.8).Conclusion:Both free drinking and intragastric administration of DSS can successfully induce the UC model in mice.Compared with the free drinking group,the intragastric administration group has low mortality rate and low coefficient of variation.Therefore,intragastric administration has more advantages than free drinking in inducing the UC model in mice.

Objective To investigate the expression of microRNA-34a (miR-34a) and silent information regulator 1 (SIRT1) in human lens epithelial cells under H2O2-induced oxidative stress.Methods Different concentrations of H2O2 (0 μmol · L-1,100 μ mol· L-1,200 μmol · L-1,300 μmol · L-1,and 400 μmol · L-1) were used to stimulate SRA01/04 cells for 24 hours.Cell viability was measured using cell counting kit-8 (CCK-8) assay.Cell apoptosis was detected by flow cytometry.Expression levels of miR-34a/SIRT1 were measured by RT-PCR.Results CCK-8 assay showed that a certain concentration range of H2O2 had a proliferation inhibition on SRA01/04 cells.There was a dose response relationship between 100 μmol · L-1 and 400 μmol · L-1.Compared with 0 μmol · L-1 H2O2 group,the difference was statistically significant (all P ＜ 0.01).According to flow cytometry results,apoptotic rate of SRA01/04 cells in control group and H2O2(100-300 μmol · L-1) groups were (6.1 ± 1.2)％,(26.3 ± 1.8)％,(32.5 ± 2.2) ％,and (64.7 ± 5.3) ％.Compared with 0 μmol · L-1 H2 O2 group,the differences were statistically significant (all P ＜ 0.01).RT-PCR test results showed that the expression of miR-34a increased significantly in a dose-dependent manner after the SRA01/04 cells treated with different concentrations of H2O2,while SIRT1 expression level was decreased,there were significant differences compared with control group (all P ＜ 0.001).Conclusion There is a significantly increase of miR-34a and decrease of SIRT1 in human lens epithelial cells under the oxidative stress of a certain concentration of H2O2.Down-regulated expression of miR-34a can increase the survival rate of human lens epithelial cells under H2O2-induced oxidative stress.

OBJECTIVE: To study the clinical value of polysomnography (PSG) and ApneaGraph (AG200) in the diagnosis evaluation of obstructive sleep apnea hypopnea syndrome (OSAHS). METHOD: From January to December in 2012, 67 OSAHS patients diagnosed by PSG were examined by AG200. The apnea hypopnea index (AHI), hypopnea index (HI), apnea index (AI), the lowest oxygen saturation (LSaO2) was were detected and the results were analyzed statistically. RESULT: Significant differences were observed in AI, AHI, LSaO2 between AG200 and PSG (P < 0.05, respectively). No statistically significant difference was found in HI. The differences in HI between AG200 and PSG were not significant (P > 0.05). AHI, HI and LSaO2 was were significantly correlated between AG200 and PSG (r = 0.870, 0.743, 0.374, 0.716, P < 0.01). CONCLUSION AG200 could not replace PSG but could identify the level of upper airway obstruction.

Objective To assess the quality of life(QOL)of advanced schistosomiasis patients,and understand its influenc-ing factors. Methods A questionnaire survey was carried out by using WHOQOL-BREF,and the information of demography, family,illness,health status,and health service was collected. Results Among the 217 advanced patients,the average age was (75.33±6.94)years,the ratio of male to female was 2∶5,89.86%of them were farmers,75.58%were illiterate or semi-illiterate, and 88.94%belonged to the splenomegaly type. Totally 61.29%of the cases had the scores over average for the overall QOL,but the scores for the health and well-being were lower. There were a significant difference among the average scores of different do-mains of QOL(χ2 =23.46,P<0.01). Both the year of being diagnosed and clinical classification was not associated with the scores of QOL. Regularly taking physical activities was significantly associated with each of all the 4 domains. The factors such as onset of acute disease in 2 weeks,taking therapeutic pills daily,marital status,age,etc. impacted the specific domains of QOL. The overall QOL and the 4 domains of the patients were at medium level;meanwhile,the score of physiological domain was lower than the scores of the other 3 domains. Conclusions The QOL(s)of advanced schistosomiasis patients in Qingpu District are rel-atively good. It is important to provide effective community health services and encourage the patients to take part in tempered sports or physical activities in order to keep their normal activities of daily living.

Spices have enjoyed a long history and a worldwide application. Of particular interest is the pharmaceutical value of spices in addition to its basic seasoning function in cooking. Concretely, equipped with complex chemical compositions, spices are of significant importance in pharmacologic actions, like antioxidant, antibacterial, antitumor, as well as therapeutical effects in gastrointestinal disorders and cardiovascular disease. Although increasing evidences in support of its distinct role in the medical field has recently reported, little information is available for substantive, thorough and sophisticated researches on its chemical constituents and pharmacological activities, especially mechanism of these actions. Therefore, in popular wave of studies directed at a single spice, this review presents systematic studies on the chemical constituents and pharmacological activities associated with common used spices, together with current typical individual studies on functional mechanism, in order to pave the way for the exploitation and development of new medicines derived from the chemical compounds of spice (such as, piperine, curcumin, geniposide, cinnamaldehyde, cinnamic acid, linalool, estragole, perillaldehyde, syringic acid, crocin).
