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.

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.

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.

BACKGROUND: Chinese character is the only non-alphabetic system of writing, the patterns of semantic symbol, phonetic symbol and sign in the cognition of Chinese characters, it is the combination of form, sound and meaning, and its cognitive pattern, pathway, analytical judgement of semantic and storage are different from those of western alphabetic system of writing, and the processing of Chinese characters maydifferent from that of alphabetic system of writing.OBJECTIVE: To localize the motor language center of the healthy volunteers whose native language is Chinese by means of the equivalent current dipole (ECD) and synthetic aperture magnetometry (SAM) of magnetoen cephalography (MEG).DESIGN: A single-sample univariate analysis.SETTING: Department of Neurology, Beijing Tiantan Hospital affiliated to Capital University of Medical Sciences.PARTICIPANTS: Ten healthy volunteers whose native language is Chinese were selected from the postgraduates and training participants in the Department of Neurology, Beijing Tiantan Hospital affiliated to Capital University of Medical Sciences between July 2003 and April 2005, they were all right handedness and had no speech disorders and cognitive impairments, and all accepted training of language task.METHODS: All the healthy subjects were given the language task stimulation of reading words and pseudowords silently, the number of the silently read nouns, appearing time for each noun and the interval between two tasks were strictly matched, ① Words were the common high-frequency characters, accorded to the law of Chinese characters components, and had 4-13 strokes. ② Pseudowords, composed by Chinese characters made-up software, accorded to the made-up law of Chinese character, but could not compose the stroke assemble of the character, and had 4-13 strokes. The evoked magnetic field produced after the stimulation was recorded with MEG, the collected data were overlapped with MRI to obtain the localization of language functional areas.RESULTS: All the 10 volunteers finished the test and entered the analysis of results. Both words and pseudowords evoked obvious late magnetic reaction waves in bilateral cerebral hemispheres, the motor language centers both located at posterior inferior frontal gyrus.CONCLUSION: The motor and classic motor language centers are general concordant in the normal people whose native language is Chinese, that was to say, the motor language center localizes at posterior inferior frontal gyrus of normal people whose native language is Chinese.

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.

Objective:To observe the effect of emergency airway established by laryngeal mask for cerebral protection, and to popularize using laryngeal mask for establishing emergency airway in cardiopulmonary resuscitation(CPR) among paramedics.Methods:To compare the rescuing effect, 49 cases of patients with cardiac arrest were divided into 2 groups as different rescue method: laryngeal mask group (23 cases), emergency airway established by laryngeal mask airway(LMA); face mask group (26 cases).Results: After aerating 5 minutes, the average oxyhemoglobin saturation has recovered to 94.1% in laryngeal mask group, and it was 78% in face mask group; heartbeat recovery rate was 100% in laryngeal mask group, and face mask group was 84.62%, and there was no statistical significant (x2=2.94,P>0.05); breathing recovery rates were 86.96% and 19.23%, respectively, in laryngeal mask group and face mask group, and there was statistical significant (x2=19.772,P<0.05); consciousness recovery rates were 43.48% and 7.69%, respectively, between the two groups, and there was statistical significant (x2=6.627,P<0.05). Conclusion: Compared with the face mask group, to establish airway for cardiac arrest patient by using laryngeal mask airway(LMA) would got efficient results in improving anoxia in cerebral, increasing spontaneous breath rate and consciousness recovery rate.

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.
