Kawasakd disease(KD) or incomplete KD(IKD) is a systemic vasculitis predominantly affecting young children.Clinical manifestations include fever with no obvious origin,skin damage,abnormalities of mucous membrane and lymph nodes.The disease is often accompanied by serious cardiovascular complications such as coronary artery aneurysm,therefore it attracts more and more attention.But arthritis or arthralgia complicates over one-third of KD or IKD patients.So early-onset arthritis is often indistinguishable from early juvenile idiopathic arthritis,especially systemic-onset juvenile idiopathic arthritis(SoJIA).KD and SoJIA are considered to be different diagnoses for children with long-term fever,rash,swollen lymph nodes,and more importantly,the treatment procedures are very different,but it is difficult to completely distinguish the two diseases,especially the IKD and early SoJIA.So in this paper,we will summarize the relationship between KD and arthritis in children,which aims to remind clinicians to pay attention for the diagnosis of KD and IKD.We suggest that physicians should be alert of the fact that they must individualize every patient's management,rather than merely care by the guidelines,which will delay the treatment.

FPGA is a kind of powerful programmable chip used in the development of digital system, and it has such advantages as large capacity, reliability and easy modification. The design of FPGA system is mainly through software method which is easy to grasp. Compared with legacy discrete circuit or ASIC, more and more FPGAs are adopted in digital systems for low cost and fast speed. On the other hand, digital system plays an important role in control system of medical equipments, so FPGA is expected to be widely used in almost all fields of medical equipment.

AIM: To investigate the concentration of bufadienolides in Liushen Pill from two enterprises. METHODS: Four kinds of bufadienolides were simultaneously determined by using HPLC with DAD detector. RESULTS: Recoveries obtained from the four kinds of bufadienolides were higher than 96%,the linearity was in the range of 1 ?g/mL-100 ?g/mL.The concentration of bufadienolides in Liushen Pill was significantly higher than that in other related TCM compatibilities. CONCLUSION: The well-distributed compatibility in Liushen Pill has an influence on the solubilization of bufadienolides,may be in relation to eahancing to release.

Objective To evaluate the academic level and the popularity of Chinese Journal of Orthopaedics from the point view of citation. Methods According to the information of Chinese Medical Citation Index (CMCI), the amount and distribution of the original articles in Chinese Journal of Orthopaedics cited by the journals included by CMCI were statistically analyzed. The data analysis included the percentage of cited articles, the number of citation of a single article, authors of most cited articles, geological regions of cited articles, citing journals, the self citing rate and years of citation. Results The percentage of cited papers (663 articles, 3728 times) in all published 1 182 articles in Chinese Journal of Orthopaedics from 2005 to 2009 was an average of 56.09%. The average time of original articles cited by other researchers was 5.62. The highest one was citated by 104 times. 210 articles (31.68% of total papers) were cited 5 or more times, and the all cited times from them were 2835 (76.04% of total cited times). 663 cited articles were written by 485 authors from different countries. The most frequently cited author wrote 12 papers. The number of authors with one paper cited was 386 (79.58% of total authors). The cited authors are from the mainland, HongKong, and Taiwan in China, as well as USA, Canada, France. Beijing, Shanghai and Tianjin are leading cities in orthopaedic research. Beijing was the first place (32.16% of total authors). There were 445 citing journals. There was 217 items self cited; the self- citing rate is 0.058. Conclusion Chinese Journal of Orthopaedics has provided high quality articles and has a strong influence in the field of medical research. It has been become an important resource for orthopaedic researchers and a vital medical journal in China.

Objective To investigate the changes of platelet activating factor ( PAF) in serum from patients with hypertensive disorder complicating pregnancy .Methods The specimens from 138 women were obtained at Department of Obstetrics , Xinhua Hospital , School of Medicine , Shanghai Jiaotong Uni-versity, between June 2008 and March 2010.They were divided into two groups:women( n =63) with hy-pertensive disorder complicating pregnancy and normal pregnant women ( n =75 ) ( control group ) .All of them delivered until maturity .ELISA was used to detect the levels of PAF in those women's serum and in the umbilical cord serum .Results The levels of PAF in hypertensive disorder complicating pregnancy group (27.46 ±13.37 ) ng/ml were no significantly different from the control group (25.48 ±11.05 ) ng/ml( P >0.05 ) .With the hypertensive disorder complicating pregnancy more deteriorative , the levels of women ser-um PAF would be higher .The levels of women's serum PAF in hypertensive disorder complicating pregnancy group were significantly higher than the umbilical cord serum [0.00(0.00-8.83) ng/mL]( P <0.05). The levels of women's serum PAF in control group were also significantly higher than the umbilical cord ser -um[0.00(0.00-7.80)ng/mL]( P <0.05).Conclusion There are some relationships between PAF and hypertensive disorder complicating pregnancy .

Command of the JCI standards and lessons learnt from practice and experience in JCI accreditation preparation,can help identify the gap between the hospitals and JCI standards.These standards can also guide the clinical pathway system,pharmacy intravenous admixture services system and medical business intelligence system.The information system built under such guidance not only makes an effective solution to existing problems,but also proves innovative.All these pave the way for successful JCI accreditation.

Quantum dots (QD),a kind of nanocrystal,are made from Ⅱ-Ⅵ or Ⅲ-Ⅴ group elements.It has been reported that compared with current conventional fluorescent markers,QD have excellent optical properties such as strong fluorescence,photochemical stability and can be used for simultaneous multi-channel imaging.Meanwhile,as nanoparticle,QD can be easily surface modified with a variety of biological molecular and can reach cancer cells easily by penetrating the tumor angiogenesis.Therefore,QD have unique advantages in targeted real-time visual imaging of in vivo tumor and have great prospects in the individual diagnosis and treatment of tumor.However,the long-term biosafety after QD into the body still needs further study.

BACKGROUND:Mesenchymal stem cells from transgenic animals carry green fluorescent protein that can be stably expressed in viable cells and can be used to rapidly screen modified cells in comparison with traditional virus and plasmids. OBJECTIVE:To study the biological features of bone marrow derived stromal cells from transgenic rats with green fluorescent protein gene. METHODS:Bone marrows were isolated from the bilateral long bones of 2-week-old transgenic rats with green fluorescent protein gene, and cultivated in conditioned culture medium to obtain bone marrow mesenchymal stem cells with green fluorescent protein gene. The passage 5 bone marrow mesenchymal stem cells with green fluorescent protein gene were analyzed by flow cytometry to detect cellsurface molecules, and were induced in calcium or adipogenic induction medium. After calcium induction, the alizarin red staining was performed to test the formation of calcium concentration. After adipogenic induction, bone marrow mesenchymal stem cells were detected with oil red O staining. RESULTS AND CONCLUSION:Bone marrow mesenchymal stem cells, stably expressing green fluorescent protein gene, were obtained successful y from the transgenic rat with green fluorescent protein gene. The cells expressed CD90, CD105 strongly, but did not express or weakly expressed CD14 andCD45. After 3 weeks of calcium induction, jacinth calcium salts could be detected in the cells by alizarin red staining. At 3 weeks of adipogenic induction, the cells showed positive oil red O staining. The green fluorescent protein gene, as report gene, exerts no effect on the cellsurface molecules and multilineage potential of bone marrow mesenchymal stem cells, which can be used as an efficient tracer.
