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.

Human parvovirus B19, generally referred to as B19 virus, has been closely associated with a variety of different autoimmune diseases due to the features of its capsid protein. B19 virus VP1 unique region protein that has sites of phospholipase A2 and several antigenic determinants is exposed on the outside of the viral capsid protein. As a result of that, B19 virus VP1 unique region protein can stimulate the host to produce autoantibodies, which induces and/or aggravates the autoimmune diseases. The biological characteristics of B19 virus VP1 unique region protein and its relationships with autoimmune diseases are de-scribed in this review based upon the published literatures and the work achieved by our research team. This review will be helpful to the prevention and treatment of B19 virus infection.

Aim To explore the mechanism of tetram-ethypyrazine ( TMP) in the inhibition of cancer cell in-vasion and metastasis, by investigating the effect of TMP on cell migration, cell invasion and cytoskeleton of HepG2 cells. Methods Using HepG2 cells as tar-get cells, cell migration of different concentrations of TMP on HepG2 cells was assayed by the scratch wound healing assay. Matrigel cell invasion assay was used to detect the effect of TMP on the invasion of HepG2 cells. The effect of TMP on cytoskeleton of HepG2 cells was detected by high content screening ( HCS ) . Results TMP inhibited the migration of HepG2 cells, and showed a time-dependent and dose-dependent manner. Moreover, TMP significantly inhibited the in-vasion of HepG2 cells ( P<0. 01 ) , and showed a cer-tain time-dependence. Furthermore, compared with control group, a significant decrease in HepG2 cy-toskeleton area was found in a dose-dependent manner ( P<0. 01 ) . Conclusion TMP can inhibit the migra-tion and invasion of HepG2 cells, and it has the poten-tial to resist tumor metastasis, and the mechanism may be associated with TMP significantly decreasing the number and area of cytoskeleton, and inhibiting the re-arrangement of cytoskeleton.

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.

Spinal muscular atrophy (SMA) is a group of neuromuscular disorders, caused by degeneration of the motor neurons in the anterior horn of the spinal cord, with prevalence of about 1 in 6000 to 1 in 10000 in newborn. The gene carrying frequency is about 1 in 40 to 1 in 50 all over the world. SMA is one of the most common autosomal recessive diseases causing infant death. SMA mainly refers to SMN1 dependent caused by SMN1 gene mutations. Noninvasiveness and specificity make genetic testing a recommended method for diagnosis of SMA. In addition to conventional methods such as neural nutrition, muscle exercise, etc., there is no specific treatment for SMA up to now. Nevertheless, HDAC inhibitors deserve attention as they are the only drugs completed Phase Ⅲ clinical trials to date. Furthermore, other ways as small-molecule SMN enhancers, induced pluripotent stem cell (iPSC), antisense oligonucleotides to correct SMN2 splicing, etc, were still on the way of in vitro stage at present.

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.
