Objective To investigate the risk factors on children with coronary artery lesions (CAL) secondary to Kawasaki di-sease(KD). Methods One hundred and forty - five patients with KD from January 1999 to December 2001 were collected. Among them, 93 cases without CAL and 52 cases with CAL. The test results, therapeutic methods and prognosis were analyzed in two groups. Results The duration of fever was longer and mean value of erythrocyte sedimentation rate (ESR) higher in group with CAL than those m the group without CAL(P0.05).The incidence of CAL was 18.8% (18/96) in patients of IVIG treatment within 10 days from onset, and 69.4% (34/49) in patients without IVIG treatment (P

BACKGROUND: The marginal division, a new sub-region in rat brain striatum discovered in recent decades, has been found to closely relate to learning and memory function of the brain. The immediate-early genes such as c-fos and c-jun participate in the signal transduction of learning and memory in the marginal division. But what other intermediate events are initiated in the marginal division in the process of learning and memory?Cyclic adenosine monophosphate (cAMP) response element-binding protein (CREBP) is an molecule essential for the formation of long-term memory,and investigation of the expression and distribution of phosphorylated CREBP in the striatum may help understand the signal transduction mechanism in the striatum during learning and memory at the molecular level.OBJECTIVE: To investigate the expression of phosphorylated CREBP in rat brain stratum during learning and memory process.DESIGN: Completely randomized controlled study.SETTING: Institute of Neurosciences, Zhujiang Hospital of the First Military Medical University of Chinese PLA.MATERIALS: This experiment was conducted in the Institute of Neurosciences, Zhujiang Hospital of the First Military Medical University of Chinese PLA between April and August 2003. Totally 48 normal male adult SD rats were provided from the Experimental Animal Center of First Military Medical University, and after two Y-maze tests, 40 rats were selected for this study (MG-2 type, Sanshengxing electricity company).METHODS: The 40 SD rats were randomized into 4 equal groups. The rats in the first group were subjected to training to acquire dark avoidance reflex in a Y maze, those in the second group underwent sham training with only light stimulation in the Y maze without electricity on the floor.The rats in the third group were trained in the Y maze with electricity on the floor but not light stimulations, with the rest 10 rats serving as the control group subjected to sham training in the Y maze without either electric or light stimulations. After the training in the Y maze, the rats were sacrificed immunohistochemical detection of phosphorylated CREBP expression in the brain striatum.MAIN OUTCOME MEASURES: Expression of phosphorylated CREBPin rat brain striatum.RESULTS: All the 40 rats enrolled in this study were examined for phosphorylated CREBP expression. Positive expression of phosphorylated CREBP was observed in the medial marginal division of the brain striatum after the rats were trained in the Y maze with electric stimulation, but no obvious expression was seen in rats in the sham training or control groups.Massive expression of phosphorylated CREBP could be observed, typically,in the hippocampus, front prefrontal lobe cortex and cingulate gyrus of the rat brain.CONCLUSION: The transcriptional factor phosphorylated CREBP in the marginal division of the striatum participates in the signal transduction for learning and memory in rats receiving Y maze training to acquire dark avoidance reflex.

OBJECTIVE To investigate the efficacy and feasibility of endoscopic surgery to manage the tumors involving naso-ethmoidal complex and anterior skull base.METHODS 19 cases of tumors involving nasal cavity,ethmoid sinus and anterior skull base were summarized retrospectively, including 3 cases of ethmoidal squamous carcinoma, 3 cases of esthesioneuroblastoma,3 cases of melanoma,1 case of plasmocytoma,2 cases of ethmoidal adenocarcinoma,4 cases of adenoid cystic carcinoma,2 cases of meningioma.RESULTS Tumors were totally removed in 18 cases and subtotally removed in 1 case,all the cases were followed up for 1 to 3 years.Of the 3 cases of melanoma,1 case died of brain metastases 1 year after surgery,1 case recurred 8 months after surgery,1 case of adenoid cystic carcinoma recurred 17 months after surgery.No recurrence were found in the rest 16 cases during 1-3 years of following-up.CONCLUSION Endoscopic surgery is a effective method for malignant tumors localized in nasal cavity and ethmoid sinus and benign anterior skull base tumors involving nasal cavity and sinuses.Indication must be carefully selected for malignant tumors and postoperative radiotherapy should be advised.

Objective To compare the changes in serum levels of high sensitive C-reactive protein (hs-CRP)and uric acid(UA)before and after atorvastatin treatment for the patients with both essential hypertension and hypercholesterolemia,and to evaluate its effects on blood pressure and left ventricular remodeling.Methods One hundred and twenty-six hypertensive patients complicated with hypercholesterolemia were randomized into group A with amlodipine 10 mg/d(n = 65)and group B with amlodipine 10 mg/d plus atorvastatin 20 mg/d(n = 61),for three months continuously.Serum levels of total cholesterol(TC),low-density lipoprotein-cholesterol(LDL-C),high-density lipoprotein-cholesterol (HDL-C),triglyeerides(TG),hs-CRP and UA,as well as blood pressure,were determined for both groups before and after treatment.Left ventricular posterior wall thickness(LPWT)and interventricular septum thickness(IVST)were measured by echocardiography and left ventricle mass index(LVMI)was calculated.Results Serum levels of TC,LDL-C,HDL-C,TG,hs-CRP and UA decreased significantly in gr6up B after three-month treatment with atorvastatin,while serum level of HDL-C increased significantly. And,systolic and diastolic blood pressure reduced in both groups,but significantly lower in group B than those in group A,after treatment(P

Objective To establish the mathematical models of stature estimation for Sichuan Han female with measurement of lumbar vertebrae by X-ray to provide essential data for forensic anthropology re-search. Methods The samples, 206 Sichuan Han females, were divided into three groups including group A, B and C according to the ages. Group A(206 samples) consisted of all ages, group B(116 samples) were 20-45 years old and 90 samples over 45 years old were group C. All the samples were examined lumbar vertebrae through C Rtechnology, including the parameters of five centrums (L1-L5) as anterior border, posterior border and central heights (x1-x15), total central height of lumbar spine (x16), and the real height of every sample.The linear regression analysis was produced using the parameters to establish the mathematical models of stature estimation. Sixty-two trained subjects were tested to verify the accuracy of the mathematical models. Results The established mathematical models by hypothesis test of linear regression equation model were statistically significant (P<0.05).The standard errors of the equation were 2.982-5.004 cm, while correlation coefficients were 0.370-0.779 and multiple correlation coefficients were 0.533-0.834.The return tests of the highest correlation coefficient and multiple correlation coefficient of each group showed that the highest accuracy of the multiple regression equation, y=100.33+1.489 x3-0.548 x6+0.772 x9+0.058 x12+0.645 x15, in group Awere 80.6% (±1SE ) and 100% (±2SE ). Conclusion The established mathematical models in this study could be applied for the stature estimation for Sichuan Han females.

Objective To investigate the development trend of drinking-water-borne endemic fluorosis in Jiangsu Province,and to provide the basis for further prevention and treatment of the disease.Methods In 2009,eight major counties were chosen,and in each county all diseased villages were classified into light,moderate and severe disease types according to water fluorine content based on historical data,and one village was chosen from each type.In monitoring villages with improved water,one source water and three tap water samples were collected,respectively.Five water samples were collected in water unimproved monitoring villages according to water well locations of the east,the west,the south,the north and the center.The fluorine content in water was determined according to the Standard Testing Methods for Drinking Water (GB/T 5750-2006).Children aged 8 to 12 were examined for dental fluorosis by Dean method.Residents over the age of 16 were examined for clinical osteofluorosis,and two monitoring counties were chosen,then one village was respectively chosen in each county,and clinically diagnosed patients with skeletal fluorosis were examined again by X-ray.Both clinical and X-ray diagnosis were on the basis of Diagnostic Criteria of Endemic Skeletal Fluorosis (WS 192-2008).Urine samples of 30 children aged 8 to 12 and of 20 adults over the age of 16 were randomly collected and urinary fluoride was determined by F-ion selective electrode method(WS/T 89-1996).Results Of all the 24 villages of 8 counties,20 villages were water improved,and water-improvedprojects ran normally in 18 villages,while scrapped in the rest 2 villages.One hundred and two samples were tested,and the mean of water fluoride in water-improved villages was 1.10 mg/L,while in water unimproved villages and villages with water improved projects scrapped was 1.90 mg/L.The prevalence of dental fluorosis was 42.51％(854/2009).The prevalence of clinical skeletal fluorosis was 23.23％ (2024/8713) and the X-ray detection rate was 32.00％ (24/75).Six hundred and sixty-four urine samples of children were determined,and geometric mean of urinary fluorine was 1.59 mg/L,while 370 adult urine samples were determined,and geometric mean of urinary fluorine was 2.20 mg/L.Conclusions Endemic fluorosis in Jiangsu Province has not been fully controlled and there are signs of recovery.We must pay attention to water improvement measures to reduce fluoride and the management and maintenance of water improvement projects,and further strengthen the prevention and control of endemic fluorosis.
