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 preliminarily explore the delineation of clinical target volume in intensity-modulated radiotherapy for para-aortic lymph node metastases in patients with gynecological malignancies.Methods A retrospective analysis was performed on 56 gynecological tumor patients with para-aortic lymph node metastases who were admitted to our department from January 2010 to September 2016.The number and distribution of metastatic para-aortic lymph nodes were determined by imaging method.Results A total of 108 positive para-aortic lymph nodes were found in the 56 patients,with 1-4(mean,2) positive para-aortic lymph nodes per patient.The mean diameter of positive para-aortic lymph nodes was 2.3 cm (1.2-4.0 cm).A total of 20 metastatic lymph nodes (19%) were located at the L4 level,38(35%) at the L3 level,44(41%) at the L2 level,and 6(5%) at the L1 level.There were 71 metastatic lymph nodes (66%) at the left side of the para-aortic region,20 metastatic lymph nodes (19%) between the abdominal aorta and the vena cava,and 17 metastatic lymph nodes (15%) at the right side of the inferior vena cava.Conclusions For patients with gynecological malignancies,nodal contouring for the para-aortic region should not be defined by a fixed circumferential margin around the vessels.The left side of the para-aortic region should be covered adequately;the upper target should be extended up to the renal artery,and needs to be further extended for patients who have nodal involvement near the renal arteries and veins.

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.

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.
