Microbiology 2008;0(08):-
According to the cultivation objectives of the plant-productive specialities, the teaching contents and methods, testing forms and experimental teaching of the course of General Microbiology have been re-formed. The reformation includes integrating, retrenching and updating the teaching contents, strengthening the fundamental knowledge, improving the classroom teaching methods and communicating in and after class in order to arouse the student’s interest and greatly spurs student’s initiative. The testing forms were also reformed to comprehensively evaluate the student’s ability of mastering and managing the knowledge. Through the reinforcement of the basic technical and scientific research training in the experiments, good teaching results have been achieved.
2.Research status of conbercept treating age-related macular degeneration
International Eye Science 2015;(8):1367-1369
Age-related macular degeneration( AMD) is one of the major reasons of blindness among the elderly in the developed countries. As AMD patients are increasing year by year, AMD has become one of the important topics of ophthalmic research to prevent blindness. Its pathogenesis is not fully understood, but many studies have shown that vascular endothelial growth factor ( VEGF ) plays an important role in the pathogenesis. With the development and application of anti - VEGF drugs, there are a variety of drugs applied to the disease. This article introduces conbercept for the treatment of AMD.

AIM: To establish the quality standard of Agui Yangxue Tablets (Radix Angelicae sinensis, Radix Codonopsis, Rhizoma Atractylodis macrocephalae, etc.) METHODS: Radix Astragali, Radix et Rhizoma Glycyrrhizae and Radix Rehmanniae praeparata were identified by TLC. The content of ferulic acid and paeoniflorin was determined by HPLC. The HPLC condition of ferulic acid was as follows: column was Diamonsil~ TM C_ 18 (4.6 mm?200 mm,5 ?m), the mobile phase consisted of acetonitrile -0.085% phosphoric acid (22 ∶ 78), the UV detection wavelength was at 322 nm, the flow rate was 1.0 mL/min with column temperature at 35 ?C . The HPLC condition of paeoniflorin was as follows: column was Diamonsil~ TM C_ 18 (4.6 mm?200 mm,5 ?m), the mobile phase consisted of acetonitrile -0.1% phosphoric acid (15 ∶ 85), the UV detection wavelength was at 229 nm, the flow rate was 1.0 mL/min with column temperature at 25 ?C . RESULTS: The developed TLC spots were quite clear. The calibration curve of ferulic acid was linear with 0.012 9-0.154 8 ?g(r=0.999 7). The average recovery was 99.32% with RSD of 1.74% (n=9). The calibration curve of paeoniflorin was linear with 0.106 8-1.602 0 ?g(r= 0.999 9). The average recovery was 98.68% with RSD of 0.98 (n=9). CONCLUSION: The established TLC and HPLC methods are exclusive, reproducible and suitable for the quality control of Agui Yangxue Tables.

Objective To explore the effect of internet + continuing nursing education teaching methodflipped classroomin the teaching of Assessment of Consciousness among junior nurses. Methods A total of 98 nurses who have graduated within two years in the third hospital of Mianyang city in Sichuan province were selected and divided into experimental group and control group by random digits table method with 49 nurses each. The experimental group used flipped classroom teaching method and the control group used the traditional teaching method. After the training, the scores of examination and nurses′ learning satisfaction were analyzed and compared. Results The scores of nurses′ learning satisfaction in the experimental group was (100.35 ± 12.21) points, learning process, learning content, learning result, learning environment, interpersonal relationship of the dimensions were (26.85 ± 3.38), (22.02±3.07), (20.90±3.15), (17.19±2.50), (13.40±1.51) points. The scores of nurses′learning satisfaction in the control group was (86.00±11.63) points, learning process, learning content, learning result, learning environment, interpersonal relationship of the dimensions were (23.63±2.81), (19.67±3.06), (17.76±3.32), (15.20±2.46), (9.74±2.74) points. There were statistical differences between two groups(t=3.46-7.97, all P=0.000). The score of nurses′examination in the experimental group was (78.19±6.11) points,the score of nurses′ examination in the control group was (49.64 ± 14.42) points, and there was statistical difference between two groups(t=10.19, P=0.000).

Study a method for the detemination of the content of polysaccharides in Gentiana farreri, and analysis of the content of polysaccharides from different producing areas. The results showed that using the anthrone-sulfuric acid method, simple operation, accurate result. Sample was measured at 620 nm absorbance after anthrone-sulfuric acid color, at this wavelength, solution absorption and glucose showed a good linear relationship; The linearity was in the range of 0.01-0.07 g x L(-1) (r = 0.996 7). The recovery rate was 99.41%, with RSD of 2.0%. Considering the experimental conditions, to determine the solid-liquid ratio 1:60, extracting time 50 min, concentration of ethanol 80%. The mass fraction of polysaccharides was the highest to reached 0.743% in G. farreri from Gansu Xiahe. This experiment has laid a good foundation for further study on G. farreri.

Objective:To observe the protective effects of Clostridium butyricum and butyrate on pancreas, liver and intestinal mucosa in rats with acute necrotizing pancreatitis (ANP), and to explore the possible mechanism.Methods:Forty Sprage-dawley rats were randomly divided into control group, ANP group,Clostridium butyricum treated group(CB group) and butyrate treated group(SB group), with 10 rats in each group by random number method. The ANP rat models were prepared by retrograde injection of sodium taurocholate into the biliopancreatic duct. Rats in CB and SB group were given intragastic administration of Clostridium butyricum 1×10 9 CFU or sodium butyrate (100 mg/kg) in 10 days once a day before modeling. Serum amylase (SAMY), lypase, ALT, AST, TBil, tumor necrosis factor alpha(TNF-α), IL-6 and HMGB1were measured after 24 h. Protein from intestinal mucosa was extracted and Western Blotting was used to measure expression of tight-junction proteins ZO-1, claudin-1 and occludin. Pancreas and liver tissues were stained with hematoxylin-eosin and scored by pathology. Results:The levels of amylase [(9365.1±716.5), (5947.3±512.0), (6517.7±269.6)U/L], lipase[(8343.7±1041.4), (6600.4±899.7), (6754.4±1046.4)U/L], AST[(560.5±72.7), (432.0±76.2), (429.8±40.5)U/L], ALT[(499.9±65.2), (385.7±46.0), (395.8±45.8)U/L], TBil[(134.2±56.2), (74.3±65.2), (81.3±35.3)U/L], TNF-α[(162.0±14.4), (100.4±6.3), (119.2±12.5)ng/L], IL-6[(161.4±26.0), (104.8±15.2), (105.5±12.7)ng/L], HMGB1[(100.1±6.7), (58.0±7.7), (63.4±7.2)ng/L] in ANP group, CB group and SB group were detected; and the pathological scores of pancreas[(11.2±1.08),(9.45±1.06), (9.04±0.89)] and liver[(2.89±0.73), (2.09±0.49), (2.12±0.52)] in ANP group,CB group and SB group were higher than those in control group[(100.6±5.20)U/L, (966.5±301.9)U/L,(30.2±6.3)U/L, (27.6±5.9)U/L, (2.4±0.6)U/L, (29.5±4.8)ng/L,(36.9±7.6)ng/L,(35.5±5.7)ng/L,(1.18±0.05),(0.56±0.09)]. However, those indexes in CB group and SB group were lower than those in ANP group, and the difference was statistically significant (all P<0.05). The expression of ZO-1 in control group, ANP group, CB group and SB group was 1.83, 0.79, 1.25 and 1.16. The expression of claudin-1 in control group, ANP group, CB group and SB group was 0.58, 0.13, 0.43 and 0.37. The expression of occludin in control group, ANP group, CB group and SB group was 1.06, 0.38, 0.82 and 0.79. The expression of TJ proteins in ANP group was significantly lower than that in other groups and the difference was statistically significant (all P<0.05). Conclusions:Clostridium butyricum and metabolites butyrate can alleviate the inflammatory response in ANP rats with liver injury, maintain the function of intestinal mucosal barrier and prevent the liver injury.
