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 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.

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.

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.
