Objective To evaluate the value of reconstruction of three-dimentional CT in development dislocation of hip(DDH)in children.Methods Twelve cases of DDH concluded 4 bilateral and 8 unilateral cases.To sum up,16 sick hips were operated and 8 normal hips were also obtained by three-dimensional CT(Hip speed Fi/x,GE Co).Results 3D reconstruction were used to show femoral head,(acetabulum) and relationship of acetabulum and femoral head respectively.The difference between FNA measurement of sick hips and those of normal hips were significant(P

Objective To investigate the clinical epidemiologic features of transient synovitis(TS) of hip in children occurred in Shen-zhen district.Methods The medical files were reviewed and a standard questionnaire was filled according to the conditions of 705 cases such as pathogeny,clinical manifestation,therapy and prognosis.Results Transient synovitis occurred in a sporadic form all the year round.The peak age of patients with TS was 3-7 years old.The ratio of boys to girls was 2.9:1.About 19.3% patients were attacked an upper respiratory tract infection and 11.9% patients attributed the symptoms to trauma or severe activities before 1 week.A varying degree of painful limp and restriction of movement at the hip were found clinically.All of cases were cured by skin traction.The incidence of recurrence was 6.95%.Conclusions Male predominance is found in TS.It is characteristic of sporadic form in the 4 seasons and intently relation to an upper respiratory tract infection and trauma or severe activities.TS is recurrent and the prognosis is good by skin traction.

Objective To discuss the indication and complication of overhead traction of olecranon for displaced extension-type GartlandⅢ supracondylar fracture of the humerus in children.Methods Total of 87 patients(Gartland Ⅲ) proceeded with overhead skeletal traction of ulnar olecranon,including 68 cases of ulnar deviation and 19 cases of radial deviation.Eighteen cases had complicating revolve deviation.According portable X-ray results in the 2nd and 5th,three-dimension adjustment was performed within 1 week.Five patients were treated by open reduction because of symptoms nerves and blood vessel compression.When X-ray examination showed good callus formation and stable reduction,the patient was discharged after the elbow was stabilized in flexion position with plaster fixation,which was removed in 2 weeks.Results Sixty-seven of 87 patients were followed-up for 18 months.All of them had excellent results except one who had permanent ulnar nerve injury.No cubitus varus was observed.Conclusions The overhead olecranon skeletal traction is a simple,effective method,because it can increase joint motion,relieve elbow swell and pain rapidly,and improve upper limb line of traction.However,open reduction shall be done promptly if there is evidence of nerve,blood vessel or soft tissue between broken ends of fractured bone within 5 days.

Acyl carrier protein is an essential component involved in the biosynthesis of DHA(Docosahexaenoic Acid) via PKS(Polyketide synthase) pathway,which takes the growing acyl chain from one enzyme to another.One cDNA clone,with high homology of ACP,was isolated from Schizochytrium sp.FJU-512 cDNA library.The deduced amino acid sequence contained 142 residues with isoelectric point of 5.04 and had the 4'-phosphopantetheine prosthetic(4'-PP) binding site.The target fragment was digested with BamHⅠ/HindⅢand inserted into the expression vector pET-30a resulting in the plasmid pET-30a/acp.The recombinant vector was transformed into E.coli BL21(DE3) and induced by IPTG.SDS-PAGE analysis demonstrated that ACP was effectively expressed.

OBJECTIVETo explore correlation between lung and large intestine and the two meridians under pathological condition in the view of meridian theory.

METHODSNinety-six cases of bronchial asthma were applied palpation at the running course of 12 regular meridians under the elbow and knees and back-shu points. And abnormal reactions were recorded, the affected meridians and back-shu points were discovered.

RESULTSThe abnormal reactions most frequently appeared on the Lung Meridian, followed by the Large Intestine Meridian, the Spleen Meridian, the Liver Meridian, the Stomach Meridian and the Triple Energizer Meridian. And the unusual reaction of the back-shu points most frequently appeared on Feishu (BL 13), and Dachangshu (BL 25) and Pishu (BL 21) followed as the next two.

CONCLUSIONThe existence of correlation between the Lung Meridian and the Large Intestine Meridians under pathological condition can be proved through meridian and acupoint palpation on bronchial asthma patients.

Objective To evaluate the multi-slice CT perfusion imaging in investigating whether edaravone can prevent and treat pulmonary thromboembolism ischemia-reperfusion injury(PTE-IRI).Methods Twenty mongrel canines were included.A Swan-Ganz catheter wag introduced into the right internal jugular vein using the Seldinger technique,and then was inserted into the pulmonary artery.Balloon occlusion of the right inferior lobe pulmonary artery for 4 h was followed by removing catheter and 4 h of reperfusion.Animals were divided into four groups of A(no edaravone during ischenmia and reperfusion),B(edaravone used only during ischemia),C(edaravone used during both ischemia and reperfusion)and D group(edaravone used only during reperfusion)(n=5 per group).Every group was divided into three time points including before ischemia,4 h after ischemia and 4 h after reperfusion.CT scan and CT perfusionwere performed at the three time points.The blood flow(BF),blood volume(BV)and mean transit time (MTT)of the bilateral inferior regional lung parenchyma were measured with the software of perfusion 3.Results CT examination showed pulmonary edema in the right inferior lung lobe at 4 h after reperfusion.(1)The BF and MTT of A,B,C and D group were[(259.4±15.7)ml·min-1·100 g-1,(293.7±7.9)ml·min-1·100 g-1,(379.4±14.5)ml·min-1·100 g-1,(382.5±16.6)ml·min-1·100 g-1]and[(3.1±0.2)s,(2.6±0.2)s,(2.2±0.1)s,(1.9±0.2)s]respectively at 4 h after reperfusion.The BF and MTT were statistically difierent(P＜0.01)between groups(A and B,A and C,A and D,B and C,B and D)except between group C and D(the P value＞0.05)at 4 h after reperfusion,but the BV was not statistically different between groups(P＞0.05).(2)The BF[(397.2±19.2)ml·min-1·100 g-1and(259.4±15.7)ml·min-1·100 g-1in group A,(393.2±16.1)ml·min-1·100 g-1and(293.7±7.9)ml·min-1·100 g-1 in group B]and MTT[(1.8±0.1)8 and (3.1±0.2)s in group A,(1.8±0.2)s and(2.6±0.2)s in group B]were statistically different(P＜0.01),but the BV[(12.0±0.9)ml/100 g and(12.2±1.0)ml/100 g in group A,(11.9±1.5)ml/100 g and(12.2±1.3)ml/100 g in group B]were not different(P＞0.05)between groups before ischemia and 4 h after ischemia.The BF.MTT and BV were not statistically significant between before ischemia and4 h after reperfusion in group C and D(P＞0.05).ConclusionsEdaravone can attenuate the degree of the PTE IRI.Multi-slice CT perfusion imaging can evaluate effect.
