Objective To discuss the recent effect of professional instruction on patients with type 2 diabetes mellitus. Methods 200 patients with type 2 diabetes mellitus were divided into the observation group and the control group. The observation group received professional instruction while the control group only got doctors'simple advice about the characteristic, results and attentions of diabetes mellitus. Various in dices were determined before and 3 months after intervention and patients compliance was evaluated 3 months after intervention. Results The indices such as blood glucose,glycosylated hemoglobin, urine trace protein, blood lipid, weight index, blood pressue and waistline were different between the two groups(P＜0.05) after intervention although no difference was seen between them before intervention(P＞0.05).The patients compliance in the observation was better compared with the control group(P＜0.01). Conclusion Application of professional instruction proved to be an effective method to alleviate the symptoms of patients with type 2 diabetes mellitus.

A method of ultra performance liquid chromatography-quadrupole-time of flight-mass spectrometry ( UPLC-Q-TOF MS) was developed to determine 35 kinds of illegally added chemical fungicides in pesticide formulations. The samples were pretreated based on the ultrasonic extraction by the solvent of methanol, and then separated on a Zorbax C18(100 mm×1. 8 mm, 2. 1 μm) column by a gradient elution with 0. 1% formic acid aqueous solution and acetonitrile as the mobile phase. The mass spectrometer was operated under positive mode. Under the optimal conditions, the recoveries at three spiked levels (0. 2, 0. 4, and 2. 0 mg/kg) were in the range of 81. 0%-101. 3% and the RSDs were 1. 0%-4. 4%. Based on the developed method, 100 samples were analyzed, and among which 6 samples were screened out chemical fungicides. The proposed method was high-efficient, accurate and reliable for the qualitatively screening of illegaly added chemical fungicides.

OBJECTIVETo optimize the condition of callus of Cinnamonum camphora induced.

METHODGC and plant tissue culture method were applied in the study.

RESULTThe effect of callus induced and the growth of callus were different in MS medium with different proportion of hormone. The ration of callus induced was the highest and the growth of callus was the most prosperous in the MS medium with 4 mg x L(-1) 2,4-D and 0.2 mg x L(-1) 6-BA. It is found that callus induced by young leaf contained borneol, but callus induced by young stem not.

CONCLUSIONThe optimization of callus of C. camphora induced is using the MS medium with 4 mg x L(-1) 2,4-D + 0.2 mg x L(-1) 6-BA. Callus induced by young leaf can generate borneol.

OBJECTIVETo identify endophytic fungi bn12 from Cinnamomum camphora chvar, borneol and analysis its volatile metabolites.

METHODThe endophytic fungi bn12 was identified by morphological observation. volatile metabolites of endophytic fungi bn12 was analyzed by gas chromatography/mass spectrography (GC-MS).

RESULTVolatile metabolites of endophytic fungi bn12 contain borneol and much indoles. The ITS sequence of endophytic fungi bnl2 is most similar to the ITS sequence of pleosporaceae fungus, particularly C. nisikadoi.

CONCLUSIONEndophytic fungi bn12 is belong to pleosporaceae fungus. It has the ability of producing broneol.
