Objective To know the primary effect of nutrition intervention in farmers. Methods The questionnaires were used to do baseline and evaluation survey. The intervention ways were used in trial group, including holding lectures, posting posters, sending out healthy material, quizzes with prizes, recommending salts low in sodium to each family, training to make healthy food by the chef; but there were no measures in control group. Results There were statistical significance in healthy awareness of nutrition, exercises and chronic diseases between two groups after intervention; However, the average intake amounts of vegetables did not reach the recommendation of diet guidelines; After intervention, the intake frequency of vegetables and fruits had statistical significance between before and after intervention in trial group, and also had statistical significance in two groups. Conclusion The awareness of healthy knowledge and attitudes has been obvious improvement, but the diets and life styles of farmers have no obvious change. The diet structure and behavior of farmers have been increasingly rational but not enough. The farmers have started to increase the intake times of vegetables and fruits and built up the conception of eating more vegetables and fruits.

Objective: To isolate and purify the polysaccharide from Cordyceps sinensis, and analyze its structure. Methods:Cordyceps sinensis was cultured by a liquid fermentation method. A water-extraction and alcohol-precipitation method was applied to ex-tract polysaccharide from Cordyceps sinensis fermentation liquor (EPS) and polysaccharide from Cordyceps sinensis mycelium (IPS). Sephadex gel chromatography was applied to isolate and purify the polysaccharide. The purity and relative molecular weight of the poly-saccharide were determined by a gel filtration method. The monosaccharide composition of the polysaccharide was identified by GC. The content of uronic acid was analyzed by sulfuric acid carbazole method. Results: The analysis results showed that the molecular weight of EPS was 78kDa. The content of polysaccharide and uronic acid was 94. 8% and 6. 0%, respectively. EPS was composed of mannose,glucose and galactose with the molar ratio of 4. 5∶8. 0∶1. 0. The molecular weight of IPS was 42kDa. The content of polysac-charide and uronic acid was 92. 5% and 4. 5%, respectively. IPS was composed of mannose,glucose and galactose with the molar ratio of 2. 8∶3. 0∶1. 0. Conclusion:Both polysaccharide EPS and IPS in Cordyceps sinensis are heteropolysaccharide.

Objective:To compare the survival rate and adverse reactions of patients with advanced hypopharyngeal squamous cell carcinoma undergoing surgery combined with chemoradiotherapy, and to analyze the prognostic factors of patients.Methods:The clinicopathologic data of 78 patients with advanced hypopharyngeal squamous cell carcinoma admitted to the Department of Radiation Oncology of the First Affiliated Hospital of Bengbu Medical University from August 2013 to December 2018 were retrospectively analyzed. The patients were divided into surgery combined with chemoradiotherapy group ( n=27) and chemoradiotherapy group ( n=51) according to different treatment methods. The median follow-up time was 46 months (20-84 months). The main observation indicators were overall survival (OS), progression-free survival (PFS) and local control rate (LCR). Cox regression model was used to analyze the prognostic factors. Results:Until July 31, 2020, 51 of the 78 patients with advanced hypopharyngeal squamous cell carcinoma died, including 6 cases of local recurrence, 11 cases of distant metastasis, and 34 cases of other causes (15 cases of hemorrhage, 15 cases of cachexia, and 4 cases of other diseases). In the surgery combined with chemoradiotherapy group, 12 patients died, accounting for 44.44%. In the chemoradiotherapy group, 39 patients died, accounting for 76.47%. The 1-, 3- and 5-year OS rates of 78 patients were 57.7%, 36.3% and 27.2% respectively, the 1-, 2- and 3-year PFS rates were 49.5%, 38.7% and 32.6% respectively, and the 1-, 2- and 3-year LCR were 53.4%, 40.0% and 34.2% respectively. The 1-, 3- and 5-year OS rates in the surgery combined with chemoradiotherapy group were 74.1%, 50.1% and 44.6%, and those in the chemoradiotherapy group were 49.0%, 29.3% and 12.8%, with a statistically significant difference ( χ2=5.142, P=0.023). The 1-, 2- and 3-year PFS rates in the surgery combined with chemoradiotherapy group were 62.1%, 54.3% and 44.4%, and those in the chemoradiotherapy group were 43.1%, 30.6% and 26.7%, with no statistically significant difference ( χ2=3.222, P=0.073). The 1-, 2- and 3-year LCR of the surgery combined with chemoradiotherapy group were 69.8%, 54.3% and 44.4%, and those in the chemoradiotherapy group were 45.1%, 32.9% and 29.6%, with no statistically significant difference ( χ2=3.576, P=0.059). The results of univariate analysis showed that tumor T stage ( χ2=7.140, P=0.008), N stage ( χ2=4.493, P=0.034) and treatment method ( χ2=5.142, P=0.023) were all independent influencing factors of the OS of patient with advanced hypopharyngeal squamous cell carcinoma; T stage ( χ2=5.807, P=0.016) and N stage ( χ2=6.587, P=0.010) were both independent influencing factors of PFS. The results of multivariate analysis showed that tumor T stage ( HR=2.121, 95% CI: 1.142-3.938, P=0.017), N stage ( HR=2.088, 95% CI: 1.144-3.811, P=0.016) and treatment method ( HR=0.430, 95% CI: 0.226-0.815, P=0.010) were all independent prognostic factors of the OS of patients with advanced hypopharyngeal squamous cell carcinoma; T stage ( HR=1.884, 95% CI: 1.011-3.510, P=0.046) and N stage ( HR=1.904, 95% CI: 1.058-3.429, P=0.032) were both independent prognostic factors of PFS. During the treatment period, there were statistically significant differences in the incidences of radioactive pharyngitis [7.41% (2/27) vs. 39.22% (20/51), χ2=8.821, P=0.003] and radioactive dermatitis [3.70% (1/27) vs. 29.41% (15/51), χ2=7.156, P=0.007] between the surgery combined with chemoradiotherapy group and the chemoradiotherapy group. However, there were no statistically significant differences in the incidences of radioactive oral mucositis [11.11% (3/27) vs. 17.65% (9/51), χ2=0.186, P=0.666], bone marrow suppression [37.04% (10/27) vs. 50.98% (26/51), χ2=1.381, P=0.240], pharynx infection [11.11% (3/27) vs. 5.88% (3/51), χ2=0.143, P=0.706] and tracheal fistula [7.41% (2/27) vs. 0 (0/51), P=0.117] between the two groups. Conclusion:The 1-, 3- and 5-year OS rates in the surgery combined with chemoradiotherapy group are higher than those in the chemoradiotherapy group, and the incidences of adverse reactions are low. T stage, N stage and treatment method are independent prognostic factors for OS of advanced hypopharyngeal squamous cell carcinoma patients, while T stage and N stage are independent prognostic factors for PFS.

Objective:To study whether gangliosides inhibit the antigen-presenting capability of epidermal Langerhans cells.Methods:In the vitro test, the purified Langerhans cells were exposed to increasing concentration of gangliosides for 5 hours at 37℃,then KLH was added and incubated for 2 hours at 37℃.At last we added HDK1 and after 72 hours of coculture, levels of IFN-? in culture supernatants were measured by ELISA. In the vivo test, immunity to the S1509a spindle cell carcinoma was induced by s.c. inoculation at weekly intervals into naive syngeneic(CAF1) for a total of three immunizations. Delayed-type hypersensitivity(DTH) was elicited 1 week after the last immunization by injection a hind footpad with TAA-pulsed Langerhans cells incubated with or without gangliosides. Footpad swelling was assessed at 24 and 48 hours with a spring-loaded engineer′s micrometer.Results:The presence of gangliosides during HDK1 activation reduced the expression of IFN-? in vitro test. Gangliosides suppressed Langerhans cells to elicit DTH against TAA in vivo test.Conclusion:Ganglioside inhibit the antigen-presenting capability of epidermal Langerhans cells.
