AIM:To study the difference of the chemical constituents between raw Radix Aucklandiae and Radix Aucklandiae roasted with wheat bran.METHODS:UV,HPLC and TLC were performed to analyze the chemical constituents before and after the processing.The constituents absorbed by wheat bran during the processing A.lappa.were isolated by silica gel CC.Their structures were identified by spectral analysis.RESULTS:The result of UV,HPLC and TLC showed that change of the chemical constituents in after the roasting had taken place.Two major chemical constituents absorbed by wheat bran were dehydrocostus lactone and costunolide.CONCLUSION:The difference in sesquiterpeneoide before and after the processing of Radix Aucklandiae may be the evidence that the roasting with bran is to the benefit of therapeutic effect.

Abstract: Relapse and metastasis are the main causes responsible for failure of surgical operation in treating malignant tumors. This article introduces the present development in post-operation treatment of lung cancer, liver cancer and stomach cancer, showing that the synthetic treatment by stages combined with traditional Chinese medicine is the important way to prevent and treat the post-operation relapse and metastasis of tumors, and suggesting the optimized method for treatment.

After being activated by the growth factor-mediated receptor tyrosine kinase phosphorylation, Akt activates a series of substrate molecules, including Forkhead transcription factors etc, which regulate cell survival and death. With the changes of Akt phosphorylation levels (Ser473) after cerebral ischemia, its upstream and downstream protein phosphorylation levels have also changed. Preconditioning may produce ischemic tolerance by changing the levels of Akt protein phosphoryiation. Dysfunction of Akt/PKB signal transduction pathway may mediated neuronal death after cerebral ischemia.

OBJECTIVE To study the distribution and drug resistance of pathogens in urinary tract infection from elderly patients.METHODS A total of 406 strains isolated from urine culture of the elderly patients were identified and their drug resistance was tested by K-B method.RESULTS Among 406 strains the Gram-negative bacilli accounted for 67.0%.The majority of Gram-negative bacilli were Escherichia coli(156 strains),Proteus,Klebsiella pneumoniae,Enterobacter cloacae,Pseudomonas aeruginosa,and Acinetobacter baumannii.Grampositive cocci accounted for 29.1% and Candida albicans accounted for 4.0%,respectively.The resistance rate of the main Gram-negative bacilli to imipenem,cefoperazone/sulbactam and amikacin was relatively low.And all Gram-positive cocci were sensitive to vancomycin.CONCLUSIONS The antimicrobial resistance of pathogens in elderly patients with urinary tract infection is serious.So it is important to monitor the antimicrobial resistance.

Objective To probe the relationships between homocysteine (Hcy) and folic acid, VB6, VB12. Methods Ninety-eight diabetes mellitus (DM) patients and 31 normal persons were recruited. Fluorescence polarization immunoassay (FPIA) was used to detect Hcy, and double labelled radioimmunoassay to detect folic acid, and VB12. Results The Hcy in DM patients was decreased in folic acid(5 mg/d) group, VB12 (1.5 mg/d), group and folic acid combined with VB12 group. but not in VB6 group. Conclusion Folic acid, VB12, and folic acid combined with VB12 can reduce Hcy in DM patients,but VB6 cannot.
