Agricultural Microbiology is a professional foundation curriculum for biology,botany and envi-ronmental majors in agricultural universities.After 1999,with the increase enrollment of the national under-graduate education and rapid construction of the university,the number of majors and students increased rapidly and quality of students and talent demand of society changed dramatically.Under such condition,in order to meet the society demand of microbiology,according to the distinguishing feature of different major groups,based on strengthening the basis teaching and stretching application teaching,new curriculum teaching model and method were explored positively,and then new curriculum system was constructed.Be-ing aroused sufficiently of the students’ subjective initiative,both the teaching quality and comprehensive quality were improved.

Cadmium (Cd) is ubiquitous in the human environment and has toxic effect on soil microbial biomass or its activity,including microbial biomass carbon (Cmic), dehydrogenase activity (DHA) and basal respiration (BR), etc., Cmic, DHA, BR were used as bioindicators of the toxic effect of Cd in soil. This study was conducted to determine the effects of Cd on soil microbial biomass and its activity in a paddy soil. The inhibition of microbial biomass and its activity by different Cd concentrations was described by the kinetic model (M1) and the sigmoid dose-response model (M2) in order to calculate three ecological doses of Cd:ED50, ED10 and ED5. Results showed that M2 was better fit than M1 for describing the ecological toxicity dose effect of cadmium on soil microbial biomass and its activity in a paddy soil. M2 for ED values (mg/kg soil) of Cmic, DHA, BR best fitted the measured paddy soil bioindicators. M2 showed that all ED values (mg/kg) increased in turn with increased incubation time. ED50, ED10 and ED5 of Cmic with M2 were increased in turn from 403.2, 141.1,100.4 to 1000.7, 230.9, 144.8, respectively, after 10 d to 60 d of incubation. ED50, ED10 and ED5 of DHA with M2 increased in turn from 67.6, 6.2, 1.5 to 101.1, 50.9, 41.0, respectively, after 10 d to 60 d of incubation. ED50, ED10 and ED5 of BR with M2 increased in turn from 149.7, 6.5, 1.8 to 156.5, 50.8, 35.5, respectively,after 10 d to 60 d of incubation. So the ecological dose increased in turn with increased incubation time for M2 showed that toxicity of cadmium to soil microbial biomass and its activity was decreased with increased incubation time.

OBJECTIVETo establish a new method for simultaneous determination of shanzhiside methyl ester, chlorogenic acid, 8-O-acetyl shanzhiside methylester, forsythiaside B, rutin, acteoside and galuteolin in Lamiophlomis rotata.

METHODSeparation was performed on a Welchrom-C18 chromatographic column with acetonitrile-0.1% orthophosphoric acid as mobile phasewith gradient elution. The flow rate was 1.0 mL x min(-1). The column temperature was 30 degrees C, and the detection wavelength was set at 238 nm, 330 nm and 350 nm.

RESULTThe seven compounds were well separated with good linear correlations. The mean recoveries of seven compounds were 96.47%-102.2% (RSD 0.70%-2.2%).

CONCLUSIONThere were good correlations among the seven compounds in the samples of aerial parts. The mean sum of shanzhiside methyl ester and 8-O-acetyl shanzhiside methylester in samples of aerial parts is 1.44%. The aerial parts have more kinds of composition and with higher content than that of underground parts in L. rotata, which was reasonable for the resonable use of the aerial part as medicinal part. The method was simple, repeatable and stable, which could be used for identification and quality evaluation of L. rotata.

Objective To observe the efficacy and security of Chinese Medicine fumigation based on tension balance acupuncture on spasticity after ischemic stroke. Methods From June, 2014 to June, 2017, 258 patients with spasticity after ischemic stroke were assigned into control group (n=130) and observation group (n=128). All the patients received routine rehabilitation and tension bal-ance acupuncture, and the observation group received Chinese Medicine fumigation in addition, for six weeks. They were assessed with modified Ashworth Scale (MAS), Fugl-Meyer Assessment (FMA), modified Barthel In-dex (MBI) and Neurological Deficit Scale (NDS) before, three weeks and six weeks after treatment. The inci-dence of side-effect was recorded. Results There was no significant difference in scores of FMA, MBI and NDS between two groups three weeks after treatment (P>0.05). Six weeks after treatment, the scores of FMA, MBI and NDS improved in both groups (t>7.382, P<0.05), and improved more in the observation group than in the control group (t>4.412, P<0.05), while the clinical efficacy on spasm was also better (χ2=11.121, P=0.001). The side-effect was slight in both groups. Conclusion Combination with Chinese Medicine fumigation can ameliorate the spasticity of upper limb in ischemic stroke patients, to promote the recovery of motor function and activities of daily living.

OBJECTIVE: To explore alcohol pharmacokinetics as well as acetaldehyde level in peripheral blood in human subjects with different ALDH2 genotypes after drinking. METHODS: Venous blood samples of 14 unrelated volunteers were collected. Polymerase chain reaction-restriction fragment length polymorphism technology was adopted for DNA extraction and ALDH2 genotyping. The volunteers were asked to drink beer at certain doses. The concentration of alcohol and acetaldehyde were assayed by headspace gas chromatography method at different time. The pharmacokinetic parameters were calculated. RESULTS: According to the results of electrophoresis, 5 people carried ALDH2*1/*1 as wild group and 9 people carried ALDH2*1/*2 as mutation group. The good linear range of alcohol and acetaldehyde were 0-1 570.7 microg/mL and 0-5.1772 microg/mL, respectively. The AUC values of alcohol and acetaldehyde and the t1/2Z value of alcohol were higher in the mutation group than that in the wild group. But the CL/F value of alcohol was lower in the mutation group than that in the wild group (P<0.05). CONCLUSION After the consumption of alcohol, alcohol and acetaldehyde metabolism in blood slow down in ALDH2*1/*2 mutation group influenced by the inhibition of enzyme activity, leading to the accumulation of acetaldehyde in peripheral blood, thus reinforcing their effects in the body.

A patented kinetic uricase method was evaluated for serum uric acid assay. Initial absorbance of the reaction mixture before uricase action (A(0)) was obtained by correcting the absorbance at 293 nm measured before the addition of uricase solution, and background absorbance (A(b)) was predicted by an integrated method. Uric acid concentration in reaction solution was calculated from A, the difference between A(0) and A(b), using the absorptivity preset for uric acid. This kinetic uricase method exhibited CV<4.3% and recovery of 100%. Lipids, bilirubin, hemoglobin, ascorbic acid, reduced glutathione and xanthine <0.32 mmol/L in serum had no significant effects. A linearly responded to 1.2 to 37.5 micromol/L uric acid in reaction solution containing 15 microl serum. The slope of linear response was consistent with the absorptivity preset for uric acid while the intercept was consistent with that for serum alone. Uric acid concentrations in clinic sera by different uricase methods positively correlated to each other. By Bland-Altman analysis, this kinetic uricase method accorded with that by quantifying the total change of UV absorbance on the completion of uricase reaction. These results demonstrated that this kinetic uricase method is reliable for serum uric acid assay with enhanced resistance to both xanthine and other common errors, wider range of linear response and much lower cost.

A patented kinetic uricase method was evaluated for serum uric acid assay. Initial absorbance of the reaction mixture before uricase action (A0) was obtained by correcting the absorbance at 293 nm measured before the addition of uricase solution,and background absorbance (Ab) was predicted by an integrated method. Uric acid concentration in reaction solution was calculated from △A, the difference between A0 and Ab, using the absorptivity preset for uric acid. This kinetic uricase method exhibited CV＜4.3% and recovery of 100%. Lipids, bilirubin, hemoglobin, ascorbic acid, reduced glutathione and xanthine ＜0.32 mmol/L in serum had no significant effects. △A linearly responded to 1.2 to 37.5 μmol/L uric acid in reaction solution containing 15 μl serum.The slope of linear response was consistent with the absorptivity preset for uric acid while the intercept was consistent with that for serum alone. Uric acid concentrations in clinic sera by different uricase methods positively correlated to each other.
