Objective To investigate the impact of health education and standard treatments on the life quality of asthmatic children.Methods We conducted clinic treatments of 110 cases of asthmatic children lasting for 6 months,which were divided into standard treatment and health education group with 60 cases and group without standard treatment and health education with 50 cases.We emphasized the education management on cases in experimental group,which strictly obeyed the Global Initiative for Asthma (GINA) to formulate classified treatments as well as regular follow-up.Control group received the same treatments as experimental group yet without emphasizing health education about asthma on parents,which was accompanied with irregular follow-up.We compared the before-treatment and after-treatment life-quality and lung functions of asthmatic children.Moreover,we used Pediatric Asthma Quality of Life Questionnaire (PAQLQ) to evaluate the before-treatment and after-treatment life quality of asthmatic children.Results After follow-up lasting for 6 months,the treatments of experiment group had obvious improvements (P ＜0.01).The improvements of peak expiratory flow (PEF) of lung function test and timed vital capacity of the first second (FEV1) of experimental group were also better than the improvements of these two metrics of control group (P ＜ 0.01).In addition,after 6 months,in both all dimensions of PAQLQ and total score,the differences between before and after treatment of experimental group were significant (P ＜ 0.01,P ＜ 0.05) ; and the differences between experimental group and control group were also significant in both all dimensions of PAQLQ score (12.4 ±2.1) and total score comparing to the control group (8.1 ±2.3),and the differences are also significant (t =2.5,P ＜ 0.01).Conclusions Health education and standard treatments significantly improved the life quality of asthmatic children with a good compliance of treatment and a low recurrence rate,which is worth of popularizing.

Objective To investigate the optimal mild hypothermia course and cerebral temperature of the neonatal rats after hypoxic-ischemic brain injury. Methods The posthypoxic-ischemic rats of experimental group (n=60) were placed in the glass jars immeresd in water bath held constaut at either 29 C or 3l C for 24h, 48h or 72h. While the rats of room temperature group (n=22) were stayed in room air. Blood glucose, blood gases and neuropathology findings were studied to determine the therapeutic effects. Results The brain temperature droped 3C or 5C when enviro ment temperature was 31C or 29C respectively. The blood glucose remained normal. Neuropathology findings reveled that the brain damage of experimental rats reduced 46%～86% compared to the room temperature group. Conclusion Reducing the cerebral temperature by 4～5 C for 72 hours after hypoxic-ischemic brain injury can lead to superior protective effect.

Objective To compare the short-term efficacy of conbercept and ranibizumab for macular edema in central retinal vein occlusion (CRVO)and explore the relationship between the integrity of ellipsoidal zone and visual acuity.Methods Forty-four eyes of 44 patients with macular edema in CRVO were enrolled into this retrospective and comparative study.There were 15 eyes of 15 males,29 eyes of 29 females;age ranged from 49-61 years old,with an average age of (54.65±3.10) years.All patients were examined with best-corrected visual acuity (BCVA),intraocular pressure (IOP),slit lamp,fundus photograph,fundus fluorescein angiography (FFA),optical coherence tomography(OCT).BCVA were examined with interactional visual chart and recorded with logarithm of the minimum angle of resolution acuity.Twenty-three eyes were intravitreal injected with conbercept 0.5 mg (group A) and 21 eyes were intravitreal injected with ranibizumab 0.5 mg (group B).There was no statistical difference of age (t =-1.41),gender (x2 =0.55),the percentage of hypertension patients (x2 =0.27),average BCVA (t =-2.06),IOP (t=-2.52),central macular thickness (CMT) (t=-1.96),number of different integrity of ellipsoidal zone patients (x2 =1.00) and number of different types of macular edema patients (x2 =1.03)among the two groups (P＞0.05).The change in BCV.A.and CMT at 3,6 months between the two groups were compared.The relationship between BCVA at 6 months and BCVA,CMT at baseline were explored.The relationship between three groups of ellipsoidal zone and BCVA at baseline were evaluated.The change of BCVA after treatment between the three groups of ellipsoidal zone were Compared.The number of intravitreal injections between two groups was compared.Results During the 3,6 months after treatment,the mean BCVA were all improved with statistically difference in group A 0=5.13,7.39;P＜0.05) and group B (t=6.60,11.52;P＜0.05).There was no significant difference of BCVA at 3,6 moths between group A and group B (t=-0.99,-0.40;P＞0.05).During the 3,6 months after treatment,the mean CMT were all decreased with statistically difference in group A (t=11.58,i5.96;P＜0.05) and group B (t=18.77,35.16;P＜0.05).There was no significant difference of CMT at 3,6 months between group A and group B (t=-1.52,-1.63;P＞0.05).In both groups,BCVA at 6 months was related to BCVA at baseline (r=0.44,0.62;P＜0.05),but not related to CMT at baseline (r=0.19,0.01;P＞0.05).In the two groups,BCVA at baseline was related to the integrity of ellipsoidal zone (r=0.97,0.70;P＜0.05).There was statistical difference of the number of intravitreal injections in the two groups (t =-6.88,P＜0.05).There was no systemic or ocular serious side effects during the follow up.Conclusions Comparing to ranibizumab,conbercept has the same effective to the treatment of macular edema in CRVO,but the number of intravitreal injections is less.The integrity of ellipsoidal zone is related to BCVA.

BACKGROUND:In recent years, many manufacturing techniques have been recently developed for soft tissue engineering scaffolds. Especialy additive manufacturing with a unique material accumulated forming principle can be feasible and reliable to manufacture the highly precise scaffolds with gradient structures and multi-materials for large soft tissue defect repairing.
OBJECTIVE:To summarize scaffolds manufacturing technologies in the soft tissue engineering applications developed in recent years and to predict the direction of development.
METHODS: A retrieval was performed for the literature about the manufacturing methods of soft tissue scaffolds using key words of “additive manufacturing, microfabrication, vascular tissue engineering, muscle tissue engineering, cartilage tissue engineering, stereolithography, 3D printing, biodegradable hydrogel” in English and Chinese, which were published between January 2010 and September 2013 in PubMed Database and China National Knowledge Infrastructure (CNKI) Database.
RESULTS AND CONCLUSION:For large soft tissue defects repairing, structure design of the scaffolds has been shifted from a simple planar structure to a more complex three-dimensional structure, and integration of scaffold structure, materials and cels, and growth factors during the manufacturing procedure can be used to obtain the resolution of vascularization. Additive manufacturings become one of the most promising approaches for the ideal soft tissue scaffolds with gradient and complex structure and multi-materials. In particular, the hydrogel/cellcomposite scaffolds fabrication, a hot but promising approach to develop the soft tissue engineering wil be made progress by the accurate principles and processes of the hydrogel additive manufacturing combined with the introduction of living cels and growth factors.

AIM: To investigate two single nucleotide polymorphisms (SNP) in the apolipoprotein(a) promoter at positions -418 and -384 and to compare distributing difference of genotype frequencies of single nucleotide among different races and to explore the influencies of them on serum lipid level and their association with coronary heart disease (CHD). METHODS: Using PCR-RFLP (BsgI,BfaI) method, we determined genotypes of these two SNPs in 156 unrelated healthy controls of HanZu Chinese and 56 unrelated CHD patients of HanZu Chinese and 56 unrelated African Blacks, then cloned polymerase chain reaction (PCR) products into T-vector and sequenced it by M13 currency primer, correspondingly. RESULTS: (1) There was no polymorphism at position -418A/A and -384C/C in control group. Only one CHD patient′s genotype determined was -418G/G, other were -418A/A and (-384C/C) in CHD patients. (2) Only two African Blacks′ genotype determined was -418G/G, other were -418A/A and (-384C/C) in African Blacks. (3) However, the Apo(a) promoter sequence was in coincident with the sequence publicized in GenBank and the base at positions -418 was adenine (A) and -384 was cytosine (C). CONCLUSION: The mutation frequencies at position -418 and -384 are low in the Chinese Han Population of Hubei and perhaps no single nucleotide polymorphisms is at two positions. No association with serum lipid levels and CHD is observed. There may be great variabilities to the SNPs in the Apo(a) promoter among different races.

Objective To observe the effect and mechanism of extracts of Liangxue Tongyu Recipe(LTR) on acute cerebral hemorrhage rats. Methods Twelve SD rats were randomly divided into sham operation group, model group, LTR water-extract group and LTR alcohol-extract group. Rats of sham operation group were injected with 2μL of normal saline into the left caudate nucleus, and rats of the other groups were injected with 2μL (0.25 U/ μL) of type Ⅶ collagenase into the left caudate nucleus to induce the model of acute cerebral hemorrhage. And then the rats of LTR groups were given intra-gastric gavage of LTR water-extract or LTR alcohol-extract. At the end of the experiment, we observed the macroscopic features of rat brain, pathological changes in rat brain under microscope after HE staining, awake time, rectal temperature, neurobehavioral scores and serum-specific enolase (NSE) level. Results Rats except for the sham operation group had various degrees of right hemiplegia symptoms, and the symptoms became severest on the third day of experiment. LTR alcohol-extract group and water-extract group had an effect on improving neurobehavioral scores, shortening awake time, and decreasing rectal temperature and serum NSE level of model rats. Conclusion LTR alcohol-extract and water-extract can relieve acute cerebral hemorrhage induced by type Ⅶcollagenase .
