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.

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.

Objective: To analyze and evaluate of the long-term follow-up data of 152 patients with inoperable malignant biliary obstruction who underwent percutaneous placement of metallic stents. Me-thods: From 2000 through 2006, 152 consecutive patients with malignant biliary obstruction were treated with PTCD or placement of metallic stents. The causes of obstruction were bile duct carcinoma (n=35),pancreatic carcinoma (n=32), hepatocellular carcinoma and metastatic (n=61), lymphadenopathy in the hepatoduodenal ligament (n=24). We used 86 stents: 31 Cook Zilver Stents,25 Sinus Superflex Stents,12 Wall Stents,3 Sinus-s Iliaca Stents,3 ZA-S Bliary Design Stents,5 Smart Stents and 7 other stents. Every three months we followed up all patients except those who died. Patient survival and stent patency rates were estimated by life-table analysis. The Kaplan-Meier method (log-rank test) was used to compare the patency and survival rates among different groups. And the COX regression model was established to compare the relative risks. Results: The overall median length of patency of all stents was 314 days. The median length of survival for the entire patient group was 215 days. The survival rate was 79.1%,51.7% and 26.8% after 3, 6, and 9 months, respectively. Six patients developed recurrent jaundice or cholangitis. The patients with hepatic hilar obstruction group indicated worse prognosis (P≤0.05). Conclusion: Metallic stents showed a favorable patency rate with regard to patient survival. In patients with hilar obstruction, the clinical prognosis was worse than that in patients with common bile duct (CBD) obstruction. We believe that the placement of metallic stents is the procedure of choice for palliation of malignant biliary obstruction.

OBJECTIVE:To establish the evaluation index system that is suitable for biological pharmaceutical industry cluster competitiveness,and provide reference for the evaluation of biological pharmaceutical industry cluster competitiveness in Jiangsu province.

Conclusion Minocycline and iodine glycerin have good efficacy in treatment of chronic periodontitis,and minocycline is more better.

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.
