This study is to establish the methods for determination of iridoid glycosides and triterpenic acids in Corni Fructus and provide technical support for the quality control of Corni Fructus. Morroniside, loganin and sweroside were determined by HPLC-UV method with acetonitrile and 0.1% formic acid as the mobile phase, and the detective wavelength was set at 240 nm. Oleanolic acid and ursolic acid were determined by HPLC-ELSD method with methanol-0.5% ammonium acetate (87:13) as the mobile phase. The results showed that the linear ranges of morroniside, loganin and sweroside were 5.335-213.4 mg · L(-1) (r = 0.9999), 5.515-220.6 mg · L(-1) (r = 1.0000), 1.992-79.68 mg · L(-1) (r = 1.0000), respectively. The average recoveries of the above three iridoid glycosides were 98.49%-99.28% with RSDs of recoveries being less than 2%. The linear ranges of oleanolic acid and ursolic acid were 7.74-154.8 mg · L(-1) (r = 0.9964), 10.82-216.4 mg · L(-1) (r = 0.9996), respectively. The average recoveries of the above two triterpenic acids were 98.11%-99.27% with RSDs of recoveries being less than 3%. The method established in this research is simple, rapid and reliable, and can be used for quality control of Corni Fructus. Furthermore, the research provided experimental data for the improvement of present quality standard of Corni Fructus, which has important significance to guarantee its quality and clinical curative effect.

This study is to analyze and identify the water soluble components of water buffalo horn (Bubali Cornu, WBH), and also establish a method for investigating these components. Shotgun proteomic analysis identified proteins in WBH aqueous extraction: keratin, collagen, desmoglein, etc. Ultrafiltration and LC-MS/MS were used to separate and identify the peptides in WBH aqueous extract, as a result, identified peptides were mainly derived from nonspecific degradation products of keratin and collagen, which including C-terminal peptides and non C-terminal peptides. Hypoxanthine, uridine, guanosine, and adenosine were identified by comparing with the standards. The strategy in present study could be used in analyzing water soluble components of animal horn derived TCM. It provides a reference for investigation of the material basis of animal horn derived TCM.

To explore the effect of different processing methods and conditions of coumarin and volatile compounds in Angelica Dahuricae Radix and their change regularity, in order to optimize and establish appropriate drying methods and conditions. After being cleaned, fresh Angelica Dahuricae Radix herbs were baked, sun-dried, shade-dried, sun-dried after sulfur-fumigation, dried by quick-lime embedding, freeze-dried, microwave-dried. Finally, 24 groups of samples were obtained after being mashed and passing through the 60-mesh screen. The HPLC-PDA method was adopted to simultaneously determine the content of coumarin compounds. The GC-MS method was used to determine the content of volatile compounds. The principal component analysis (PCA) was made on the standardized analysis results for the 24 groups of samples processed with different drying methods. According to the PCA results, the comprehensive scores of coumarin and volatile compounds in Angelica Dahuricae Radix herbs processed with different methods in the order from high to low were that unpeeled and dried by quicklime embedding > unpeeled and dried with hot-air at 100 degrees C > unpeeled and dried with hot-air at 40 degrees C > peeled and infrared-dried > peeled and dried with hot-air at 60 degrees C > peeled and dried with hot-air at 40 degrees C > peeled and sun-dried > peeled and dried with hot-air at 60 degrees C > peeled and dried with hot-air at 100 degrees C > peeled and microwave-dried > peeled and dried with hot-air at 80 degrees C > unpeeled and sun-dried > unpeeled and dried with sulfur-fumigation > peeled and dried with sulfur-fumigation > unpeeled and dried with hot-air at 120 degrees C > unpeeled and freeze-dried > unpeeled and infrared-dried > peeled and dried with hot-air at 120 degrees C > peeled and freeze-dried > peeled and dried by quicklime embedding > unpeeled and dried with hot-air at 80 degrees C > peeled and shade-dried > unpeeled and shade-dried > unpeeled and microwave-dried. According to the findings, different drying processing methods have certain impacts on the content coumarin and volatile compounds in Angelica Dahuricae Radix herbs. The traditional method of drying by quicklime embedding is recommended as the optimum origin processing method of Angelica Dahuricae Radix, which is followed by the method for being peeled and dried with hot-air at 100 degrees C.

Objective To determine the changes of interleukin-12(IL-12) and IL-12 mRNA in gastric mucosa of children with helicobacer pylori (Hp) infection,and to study the effects of Hp infection on the expression levels of IL-12 and IL-12 mRNA,and to evaluate its possible roles in the pathogenesis of gastric mucosal inflammation in Hp related gastroduodenal diseases.Methods Biopsy specimens were taken from the antral mucosa on endoscopy in patients with or without Hp infection, which were diagnosed by urease test and Giemsa staining. The expression levels of IL-12 and IL-12 mRNA in gastric mucosa were determined by ELISA and RT-PCR.Results Inflammation of gastric antral mucosa was more severe in Hp-positive mucosa .The expression levels of IL-12 and IL-12 mRNA in Hp-positive mucosa were (66.42?15.15) ng/g and (59.21?15.03)%,which were more than those in (Hp-negative )(22.22?8.79) ng/g and (17.94?7.39)%(P

Objective To investigate clinical features and antibiotic resistance of pseudomonas aeruginosa (PA) strains isolated from patients with diabetic foot infections (DFI) in Tianjin Metabolic Diseases Hospital.Methods Eighty-five PA strains were isolated from 428 patients with diabetic foot in the hospital from Jan 2008 to Dec 2010.The clinical features of patients were summarized.Relationships between the isolates and depth of ulcer or severity of infection were analyzed.The disk-diffusion method was performed to examine antimicrobial susceptibility.Results Gram positive (G+) and Gram negative (Gˉ) isolates were 50.47％ and 41.12％,respectively.Multidrug-resistant PA composed 32.9％ of the total PA isolates.The size of ulcers with PA infections was bigger than those with non-PA bacterial infections (P＜0.05).Compared to G+ strains,patients with PA strains were older,had lower hemoglobin,but higher serum sensitive C-reactive protein; and more frequently,they had ischemic ulcer and osteomyelitis.Compared to G+ strains,the PA strains were more frequently isolated from deeper ulcers and with more serious infections(P＜0.05).The resistant rates of PA to cephalosporins,fluoroquinolones,and aminoglycosides were between 32.9％-61.2％,37.6％-42.4％,and 37.6％-62.4％,respectively.Only one out of 85 PA strains was imipenem-resistant.However,sensitiveness of all PA isolates to cefoperazone and sulbactam reached 100％.Conclusion PA strains are mainly found in patients with deeper ulcers and more serious infections.Multidrug-resistant PA is common in DFI.It is important to isolate pathogens and determine their antibiotic resistance correctly in diabetic foot patients in order to provide appropriate drug administration and to reduce the production and dissemination of drug resistant strains.
