AIM AND METHODSThe purpose of this investigation was to determine the changes of erythrocyte deformability, band-3 protein and actin in the definite volume of erythrocyte membrane after high intensity running training and recovery in rats.
RESULTSLong-term training could significantly improve erythrocyte deformability and the quantity of membrane proteins. Erythrocyte deformability, band-3 protein and actin decreased transitorily at varying degrees after inadaptable high intensity exercise. One and two week training could improve erythrocyte deformability, the quantity of band-3 protein and actin after recovery.
CONCLUSIONAlterations of erythrocyte membrane protein after high intensity training could cause the change in erythrocyte membrane structure and hence influenced erythrocyte deformability. That was maybe one of mechanisms of training effecting erythrocyte deformability.

Objective To study the changes and significance of serum beta 2-microglobulin(?2-MG),cytocine interleukin-2(IL-2) in the clinical progress of childhood idiopathic thrombocytopenic purpura(ITP).Methods One hundred and ten patients of childhood ITP were chosen for the test group(70 cases of primary ITP and 40 cases of recurrent ITP),and 110 normal children for the control group.Levels of serum ?2-MG and IL-2 were determined by radioimmunoassay kit and analysed with two sample t-test.Results Among the patients,the serum IL-2 levels were significantly lower and serum ?2-MG levels were significantly higher than those in control group(P0.05).Conclusion Determining serum IL-2 and ?2-MG levels has important significance to reflect the progress of disease and direct treatment.

Objective To investigate the method and value of adjustable interatrial fistulization in the operation of congenital heart disease(CHD) accompany with severe pulmonary arterial hypertension(PH).Methods Twenty-seven patients(19 male,8 females) accompany with severe PH were entered the study,age ranged from 4 to 14 years old,weight from 13.7 to 42.0 kilogram.The enrolled diseases included 11 cases of atrial septal defect(ASD),10 cases of ventricular septal defect(VSD),4 cases of patent ductus arteriosus(PDA),and 2 cases of Ebstein syndrome accompany with severe tricuspid insufficiency.All patients were diagnosed as CHD accompany with severe PH(bidirectional shunt)which was the contraindications for routine operation before operation through chest X-ray,electrocardiography,ultrasonic cardiography,cardiac catheteri-zation and cardiac angiography.Results With adjustable interatrial fistulization and treatment to the abnormalities,14 fistulaes were closed immediately after operation,7 fistulaes were closed 2 days after operation,3 fistulaes were closed 3 days and 1 fistulae was closed 4 days after operation and accompanied with empyema discharged initiatively.One fistula was never closed,1 case died from low cardiac output symptom.The effective rate was 92.6%,closed to that of routine operations.Conclusion Adjustable interatrial fistulization is an easy procedure,and it can decrease the danger of PH post-operation effectively and provide operation opportunity for those patients with CHD approaching terminal stage.

Introduction:Neonatal tetanus is a major cause of neonatal mortality in many developing countries and remains a major public health problem. This study aimed to determine risk factors associated with neonatal tetanus in Wenzhou, China.Methodology:Medical records of neonatal tetanus cases from 17 hospitals over a 13-year period (2000–2012) were reviewed for potential risk factors. Controls were selected from neonates with diseases other than tetanus who were admitted to the same facility during the same period. The potential risk factors of the neonatal tetanus group were compared with the control group using univariate analysis and an unconditional logistic regression model.Results:A total of 246 neonates with tetanus and 257 controls were included in this study. Univariate analysis showed that having untrained birth attendants, home delivery, an unsterile method of delivery and being a migrant to Wenzhou were significantly different between the two groups (

OBJECTIVETo study the combination of Mandibular distraction and orthognathic techniques for the reconstruction of adult hemifacial microsomia.
METHODSThe three-dimensional CT reconstruction data was used with Mimics for preoperation design. The osteotomy location, distraction vector, distraction distance were decided before operation with a surgical guider. At the first stage, internal distractor was implanted after ostetomy through an extra-oral approach. The distraction begun 5-7 days after operation with a frequency of 1 mm/day. After distraction, the distractor was maintained for 3-6 months. At the second stage, the distractor was removed. Le Fort I osteotomy was performed in order to correct the cross-bite and improve the facial contour. Usually, bone graft was inserted into the gap after Le Fort I osteotomy. The genioplasty was also performed if necessary.
RESULTS9 cases of adult hemifacial microsomia with severe mandibular deviation were treated. The facial asymmetry were improved greatly. 1 patient suffered an wound infection in the maxillary region after Le Fort I osteotomy and healed uneventfully with wound irrigation.
CONCLUSIONSMandibular distraction combined with orthognathic surgery is an effective procedure for adult hemifacial microsomia with complicated mandibular hypoplasia.

OBJECTSTo investigate the distribution of vitamin D receptor (VDR) genotypes among the Hans of a lead contaminated mine in Shanxi and explore the relationship between blood lead levels and the genetic polymorphism of VDR gene.
METHODSVDR genotypes were determined by polymerase-chain-reaction and restrictive fragment length polymorphism (PCR-RFLP) and the blood lead level was measured by using the graphite furnace atomic absorption spectrometry in a population of 120 pre-school children aged 5 - 6 years who were from the mine kindergarten and were unrelated Hans. An environmental questionnaire in relation to blood lead level was filled for each subject.
RESULTS(1) The gene distribution of the VDR phenotypes in these children was VDRBB, 1.7%; VDRBb, 9.2%; VDRbb, 89.2%. (2) The mean blood lead level of the children who had VDR B allele [(0.910 8 +/- 0.265 0) micromol/L] was significantly higher than that whose VDR genotype was bb [(0.740 1 +/- 0.270 1) micromol/L (mean +/- standard deviation)] (t = 2.155, P < 0.05). (3) Many factors were found to affect the blood lead levels, such as the VDR genotype, the type of fuel, educational level of mothers and so on. After controlling the possible confounding variables by multiple regression, the contribution of the VDR phenotype to the blood lead levels was still statistically significant.
CONCLUSIONThese results indicated that the frequency distribution of the VDR genotype in these children was apparently different from that in Caucasians who had high frequencies of VDR B. The results also indicated that the individuals carrying the VDR B allele were more susceptible to lead poisoning.

OBJECTIVETo evaluate wear resistance and hardness of three kinds of new composite resins.
METHODSThree kinds of new composite resins, Solidex, Spectrum, Filtek Z350, were tested. Enamel as control group. A refited MG-200 wear machine was used in this study. Scanning electron microscope (SEM) was used to observe the friction surface of each tested material. Hardness of each tested material was determined by Vickers indentation technique. The data of wear and hardness were analyzed by Mann-Whitney test and 1-way ANOVA. The relationship between the hardness of the composites and the amount of wear of them was determined by a regression analysis method.
RESULTSFiltek Z350 showed the lowest volumetric wear and highest Vickers hardness in the composites (P < 0.05). No significant differences in wear and hardness were observed between Solidex and Spectrum (P > 0.05). Significant relationships were observed between the hardness of the composites and the amount of wear of them (r = 0.968 6) (P < 0.05). Different wear characters of the friction surface of the tested materials were observed by SEM.
CONCLUSIONNanofilled composite was superior to the hybrid composite in wear resistance and hardness.
