Objective To analyze the clinical characteristics,therapy and follow-up of the patients with ulcerative colitis (UC).Methods Collect the date of 77 inpatients with UC at the Second Affiliated Hospital of Chongqing Medical University be-tween November,2009 and october,2014,and assigned the patients randomly.Results 69.9% of the patients who were in the ac-tivity stage were moderate severity.E2 (46.6%,34/73)and E3 (50.7%,37/73)were the common lesions range.The main clinical manifestations were abdominal pain,diarrhea,mucopurulent bloody stool and bloody stool.The enteroscopy mostly showed that in-testinal mucosa hyperemia,eddma,erosion,and small ulcers had the common features of UC.The common biopsy results were chro-nic inflammation and/or erosion.The average value of serum ALB decreases while the severity of UC patients increases.Drug thera-py was the main treatment of UC.The maintenance therapy was aminosalicylic acid,the effective ratio of treatment is 89.0%(55/73).Conclusion UC treatment plan basically follow the consensus and we should enhance the follow-up of UC patients.

Objective To explore pathogenes and pathogenesis of acute cerebral infarction (ACI) from the perspective of integrated traditional and western medicine.Methods To categorize the tongue and pulse manifestation of 64 ACI patients and calculate their frequency,constituent ratios.Meanwhile,patients' blood pressure and laboratory examination results are given descriptive and statistical analysis,showing their means and standard deviations,etc.Results The frequency of dark-red tongue,thin-greasy tongue fur,greasy-yellow tongue fur and taut-slippery is respectively 48,34,20,and 41,constituting 77.4％,54.8％,32.3％,64.1％ of the patients examined respectively; Mean and standard deviation of systolic blood pressure (SBP),total cholesterol (TC),white blood cell (WBC),neutrophil percentage (NEUT％),fasting plasma glucose (FPG),and hemoglobin A1c (HbA1c) is respectively (141.20± 19.20)mm Hg (1 mm Hg=0.133 kPa)、(4.47±0.97) mmol/L、(7.83±2.63) × 109/L、(71.61±9.65)％、(6.16±2.25)mmol/L、and (6.60±1.66)％.Conclusion In terms of pathogens,wind,stasis,heat (fire) and turbid pathogen (phlegm,dampness,etc.) are important factors in bringing out ACI; In respect of ACI pathogenesis characteristics,healthy qi is slightly damaged and pathogenic qi is exuberant.Yet,the role of modern medical examination results,such as blood pressure,blood glucose,blood lipids etc.in the assessment of ACI pathogens and pathogenesis awaits further exploration.

OBJECTIVEThis study aims to evaluate the nasolabial angle change and the correlation analysis ot Angle'Is Class II division 1 malocclusion patients with vertical growth pattern after tooth extraction orthodontic treatment and provide experimental results to help in making orthodontic treatment plan and treatments.

METHODSA total of 38 Angle's Class II division 1 malocclusion patients with vertical growth pattern and tooth extraction orthodontic treatment were included in this study. Pre- and post-treatment cephalometric X-rays were performed, and 18 measurement items were measured. The change values of pre- and post-treatment, youngsters, and adults were compared to analyze the correlation of the nasolabial angle change.

RESULTSThe nasolabial angle between youngsters and adults was enlarged after treatment, but the nasolabial angle of the adult group changed more significantly. Ul to FH, Ul to NA, U1-NA, Spr-Ptm were reduced after treatment, and the adult group decreased more significantly. The upper lip sulcus and flange thickness, A'-Ptm, upper lip length, and nose prominence were enlarged after the adolescent treatment, but the adult had a certain degree of decrease. The difference had statistical significance. In the correlation of the nasolabial angle change analysis of the two groups, namely, Ul to FH, Ul-NA and U1 to NA had significant negative correlation, significant positive correlation to the upper lip inclination angle, and more significant correlation in the adult group. Upper lip flange thickness and nasolabial angle were negatively correlated, and the upper lip sulcus thickness was positively correlated. However, no significant correlation was observed between these two in the adult group.

CONCLUSIONThe nasolabial angle change of adolescents with vertical growth pattern in class II division 1 malocclusion after extraction treatment is related to the upper anterior teeth hard tissue and upper lip soft tissue, whereas only adults and upper anterior teeth hard tissue are related.

Objective To investigated the expression of scavenger receptor A(SR-A) and lipopolysaccharide(LPS) receptor CD14 in endotoxin-induced acute liver injury.Methods Ninety Wistar rats were randomly divided into endotoxaemia group(LPS group) and normal saline group(NS group).The model of endotoxaemia and acute endotoxin-induced liver injury was established by injection of endotoxin(5mg/kg) via tail veins in LPS group,while the rats in NS group received injection of 0.2ml normal saline as control.At 0,1.5,3,6,12h after injection,the levels of endotoxin,TNF-?,IL-1,alanine transaminase(ALT) and total bilirubin(TB) in plasma,SR-A and CD14 expressions in liver tissues were determined,pathological changes of liver tissues and ultrastructural changes of Kupffer cells(KCs) were observed by light and electron microscopy respectively,while the phagocytosis of KCs was determined too.Results Compared with NS group,KCs were activated on morphology and functions(proliferated diffusely,enlarged in size and increased in phagocytosis function),levels of TNF-? and IL-1 increased markedly,the pathological changes of cell degeneration and necrosis and the liver function were gradually aggravated,while SR-A expression decreased and CD14 expression increased obviously(P

Objective To investigate the optimal time and molecular mechanism of gene therapy for promoting distraction osteogenesis by observing the effect of gene transfecting at different time on expression of cyclins in mandibular distraction area.Methods Forty eight New-Zealand rabbits were employed.After accomplishing bilateral mandibular distraction osteogenesis model,the rabbits were randomly divided into the group A,B,C and D.The group A,B and C were transfected by recombinant plasmids pIRES-hBMP2-hVEGF165 2 μg(0.1 μg/μL)at the distraction area instantly after operation,on postoperative 4,14 d and given local electroporation stimulation.The four groups entered the consolidation stage after 10 d continuous traction at a rate of 1 mm/d on postoperative 4 d.Three rabbits in each group were respectively sacrificed on 7,14,28,56 d of the consolidation stage.The expression of cyclin A,D1,and E of fresh bone tissue in distraction area were detected by immunohistochemical staining.Results Cyclin A,D1,and E were strongly expressed in the traction gap on 7,14 d of consolidation stage found,which was strongest on 7 d,moreover the group A,B and C were stronger than the group D.The expression in each group was weakened on 28,56 d.The expression on 7 d in the group B was stronger than that in the4 group A,C and D(P<0.05),the expression had no statistical difference between the group A and C(P>0.05),but all were stronger than the group D(P<0.05);the expression in the group B and C on 14 d was stronger than that in the group A and D,but the expression had no statistical difference between the group B and C and between the group A and D(P>0.05).Conclusion The high expression of cyclin A,D1 and E can promote the cellular division,proliferation and differentiation in distraction area,thus accelerates the new bone formation in the distraction area,prompting that the distraction period is the best time for distraction osteogenesis under gene therapeutic intervention.
