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.

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.

OBJECTIVE:To learn the way to improve innovation efficiency of technological development and achievement transformation stages in pharmaceutical industry in China. METHODS:The input and output data of pharmaceutical industry in 28 provinces(regions,cities)of China from 2001-2013 were estimated by using stochastic frontier analysis(SFA)so as to obtain in-novation efficiency of two stages. According to average efficiency of two stages,pharmaceutical industry of 28 provinces(regions, cities)were divided into 4 categories for further analysis. RESULTS & CONCLUSIONS:The innovation efficiency of pharmaceuti-cal industry in China was 0.626 2 at technology development stage and 0.567 8 at transformation stage,indicating they were not high either and the transformation efficiency was lagged behind the development efficiency. The coefficient of variation of innova-tion efficiency at transformation stage(0.274 2)was higher than development stage(0.194 5),indicating the difference degree of innovation efficiency at transformation stage was larger than at development stage. The areas with higher efficiency in both stages were in Eastern and economically developed regions,and the Western region with rich natural resources had higher efficiency at technological development stage,indicating region economic level or resource advantages created the conditions for the pharmaceuti-cal industry to enhance the innovation efficiency. It is suggested to further strengthen scientific achievement communication between pharmaceutical enterprises and pharmaceutical research institutions,and pay more attention to develop national medicine and tradi-tional Chinese medicine in Western region.

Objective To approach the mechanisms and myocardial protective effect of Qishen Yiqi dropping pills on rats with myocardial infarction. Methods Sixty clean healthy male Sprague-Dawley (SD) rats were randomly divided into sham operation group, model group and observation group (each n = 20). The rat model of acute myocardial infarction (AMI) was established by ligation of left anterior descent (LAD) branch of coronary artery. After modeling, the rats in observation group were given 0.135 g/kg of Qishen Yiqi dropping pills, and sham operation group and model group were administered the same amount of normal saline, once a day for consecutive 28 days. At the end of treatment, the levels of serum inflammatory factors of leukotriene B4 (LTB4), prostaglandin E2 (PGE2), tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6) were measured by enzyme linked immunosorbent assay (ELISA); the changes of the indexes of hemodynamic [left ventricular systolic pressure (LVSP), left ventricular end-diastolic pressure (LVEDP), the maximal rate of increase/decrease in left ventricular pressure (±dp/dt max)], the ratio of the heart weight/body weight, and the ratio of the left ventricular weight/heart weight (LVW/HW), the myocardial infarction area, myocardial histopathological changes were observed in the three groups; myocardial tissues inflammatory related factors [the mRNA and protein expressions of cytosolic phospholipase A2 (cPLA2), cyclooxygenase-2 (COX-2), 5-lipoxygenase (5-LOX)], and the expression levels of transforming growth factor-β (TGF-β)/Smads signal transduction pathway related protein (TGF-β1, Smad2/3, Collagen Ⅰ, Collagen Ⅲ ) and cell apoptosis related factors (Bcl-2, Bax) protein were measured. Results Compared with the sham operation group, levels of serum inflammatory factors, the index of LVEDP, the ratio of the heart weight/body weight, LVW/HW, myocardial infarction area, the mRNA and protein expression levels of inflammatory factors in myocardium, the expression levels of TGF-β/Smads signal transduction pathway related protein and the cell apoptosis related factors protein in model group were all significantly elevated, while LVSP and ±dp/dt max were obviously decreased in model group. Compared with the model group, the levels of inflammatory factor in serum [LTB4 (ng/L): 370.11±46.98 vs. 633.23±83.37, PGE2 (ng/L):48.75±26.35 vs. 131.25±29.75, TNF-α (μg/L): 177.28±22.65 vs. 248.47±16.21, IL-6 (μg/L): 493.22±165.99 vs. 638.41±191.66], LVEDP [mmHg (1 mmHg = 0.133 kPa): -2.03±2.98 vs. 7.03±1.39], the ratio of the heart weight/body weight [(6.53±0.11)% vs. (7.14±0.24)%], LVW/HW (0.26±0.01 vs. 0.32±0.02), myocardial infarction area [(27.21±2.87)% vs. (44.98±1.52)%], mRNA and protein expression of myocardial inflammatory factors, the expression of TGF-β/Smads signal transduction pathway related protein, and the protein expression of Bax were all significantly decreased in observation group (all P < 0.05), LVSP (mmHg: 129.01±11.93 vs. 108.11±12.69), the +dp/dt max (mmHg/s: 3101.3±378.6 vs. 2105.3±245.9), the -dp/dt max (mmHg/s: 2612.4±249.7 vs. 1654.4±188.1), while the protein expression of Bcl-2 in observation group were obviously increased (all P < 0.05). It was demonstrated by hematoxylin-eosin (HE) staining that there were no obvious pathological changes in the sham operation group; obvious infiltration of inflammatory factors in myocardium was shown in model group; pathological changes in the observation group were significantly improved as compared with those in the model group. It was shown by Masson staining that there were slight hyperplasia of myocardial fibers and no obvious pathological changes in the sham operation group. Severe collagen hyperplasia was found in model group, and the degree of fibrosis in the observation group was significantly improved. Conclusions Qishen Yiqi dropping pills can reduce the degree of myocardial fibrosis and inhibit the ventricular remodeling via TGF-β/Smads signal transduction pathway. The dropping pills can also suppress the release of inflammatory factors by reducing cPLA2 to decrease the inflammatory response and inhibit apoptosis and alleviate myocardial injury by up-regulating the expression of Bcl-2 and down-regulating the expression of Bax.
