OBJECTIVE:To establish a rapid determination method for 9 kinds of glucocorticoid and 8 kinds of non-steroidal anti-inflammatory drugs illegally added into anti-rheumatic TCM patches. METHODS:UPLC-MS/MS method was adopted. The samples were separated on Acquity UPLC? BEN C18 column with methanol-water(90:10,V/V)as mobile phase at flow rate 0.4 mL/min. The column temperature was set at 30℃,and sample size was 1μL. The ionization mode was electrospray ion source(ESI):spray needle voltage of 5500 V,ion source spray GS1,GS2 pressure of 50,50 psi,ion source temperature of 500 ℃,scanning range of m/z 50-500. The multiple reaction monitoring(MRM)combined with information-dependent acquisition (IDA) and en-hanced product ion scanning(EPI)was used to rapid qualitative analysis. RESULTS:The detection limits for 17 kinds of chemical components were not more than 0.400 μg/mL. RSDs for precision,repeatability,stability tests were not more than 4.93%,7.69%, 9.57%,respectively. Diclofenac sodium was detected in the sample. CONCLUSIONS:The method is selective and sensitive. It is suitable for qualitative analysis of chemicals illegally added into anti-rheumatism TCM patches.

Objective: To determine the effects of active constituent of Radix Ranunculi Ternati on immune function of experimental animal.Methods: Immune suppression mouse models were made by cyclophosphamide method.After intragastric administration,the effects of polysaccharide and saponin of Radix Ranunculi Ternati on phagocytosis of peritoneal macrophage,formation of hemolysin and T-lymphocyte population of peripheral blood were observed and compared.Results: These two active constituent can highten the percent and the index of phagocytosis,enhancement the formation of the hemolysin obviously and increase the number of T-lymphocytes in peripheral blood.Conclusion: The active part of Radix Ranunculi Ternati can stimulate the immunologic function of immune suppression mouse models.

A new compound and five known compounds were isolated from the ethanolic extract of the leaves of Ilex pernyi Franch. Their structures were established on the basis of spectral analysis and identified as trans-isoeugenyl-α-L-arabinopynosyl(1→6)-β-D-glucopyranoside (1), kaempferol-3-O-sambubioside (2), quercetin-3-O-sambubioside (3), isoquercitrin (4), (+)-syringaresinol-O-β-D-glucopyranoside (5), amarantholidoside IV (6). Among them, compound 1 is a new phenolic glycoside, named as ilexperphenoside A, and compounds 2-6 were isolated from this plant for the first time.

Objective To investigate the clinical effect of elbow anterolateral approach with internal fixation in the treatment of capitellum fractures.Methods 12 patients with capitellum fractures were divided into types according to Bryan-Morrey classification:type Ⅰ (n=8),type Ⅱ (n=2),type Ⅳ (n=2).Patients were treated with anterolateral approach with AO cannulated screw fixation.Curative effect was evaluated according to Broberg-Morrey scale.Imaging evaluation was conducted.Results No lateral collateral ligament injury,blood vessels or nerve injury were found in patients.Primary healings were obtained after operation.All patients were followed up for 8 to 26 months postoperatively (averaged 16 months).All fractures were healed at 5 to 9 weeks after operation (averaged 7.2 weeks).Postoperative elbow flexion and extension was averaged (127.2±12.8) ° and forearm rotation was averaged (154.6 ± 15.3)°.Postoperative Broberg-Morrey score was averaged 90.5.The 8 cases were excellent,3 cases good and 1 case poor.Conclusions Operation should be applicated according to fracture classification in the treatment of capitellum fractures.Anterolateral approach is better to expose the fracture,which is convenient for operation,and AO cannulated screw fixation can fix the fractures firmly.Clinical effect is satisfactory when taking early functional exercise for elbow joint.

The rapid development of silicon microelectrode arrays provides an ideal means for the study of spatio-temporal features of neuronal activity in the brain. The stability of the linear silicon electrode array (LSEA) in recording neuronal potentials and its validity in recording unit activity are investigated. The experimental results showed that during the recording of field potentials in the hippocampal CA1 region of anesthetized rats, upward and downward movements of the recording probe for a distance of 200 ?m did not affect the orthordromic and antidromic evoked potentials significantly. The data indicated that the probe movements caused very small damage to the neurons, and the recording was stable. The contact sites that located in the pyramidal cell layer acquired CA1 neuronal unit activity validly. Different types of unit activity from independent neurons were easily distinguished in epochs of recording from a same recording site. These results demonstrated the features of the LSEA, including the facility of probe manipulation, the stability of recording and the abundance of data acquirement. The data will be helpful to the researchers involved in the application of microelectrode array for neuroscience researches.

BACKGROUND:Nano-size inorganic filling greatly improves mechanic characteristic of composite resin.However,its effects on pulp tissue remain unclear.OBJECTIVE:To evaluate the biocompatibility of FiltekTM Z350 nano-composite resin on dog pulp tissue by means of histology observation.DESIGN,TIME AND SETTING:Randomized control animal experiment was performed at the animal experiment center of Fuzhou General Hospital,Nanjing Military Area Command of Chinese PLA from April 2007 to April 2008.MATERIALS:Sixty healthy teeth from three adult male beagle dogs were recruited in this study.METHODS:Buccal Class V deep cavities were prepared in beagle dogs,which were then divided into four groups at random.FiltekTM Z350 resin,Dyract AP compomer and TPH resin were used to restore the cavities in three testing groups and glass ionomer cement was used as control.All cavities were treated with Clearfil SE BOND before filling.Intact healthy teeth were used as blank control.MAIN OUTCOME MEASURES:The pulp condition of each tooth was studied histologically.The remaining dentine thickness of each cavity was measured.RESULTS:After 7 days,mild inflammatory response was observed in most of the specimens.After 30 and 90 days,normal histological characteristics were observed in almost all specimens except TPH resin group.The histological structure disturbance of dentin cell layer emerged in some specimens of TPH group,which was higher than other testing groups(P 0.05).CONCLUSION:FiltekTM Z350 nano-composite resin has similar biocompatibility as Dyract AP compomer and glass ionomer cement,better than TPH resin.
