ObjectiveTo investigate the delayed umbilical cord clamping in preterm children of anemia in premature children.Methods60 preterm children were randomly divided into study group and control group 30 patients in each group.The control group was taken regular off umbilical,the observation group delay 90s(after birth at least 2min) off umbilical.ResultsThe Hb, HCT, and SI in the postnatal 1,2,4,8 weeks were significantly lower than the observation group, the difference was statistically significant (all P ＜ 0.05), and the control group after birth in preterm children Ret in the first week was significantly higher than 2,4 in the observation group, the difference was statistically significant(all P ＜ 0.05) ; The observation group at 6 months the incidence of anemia(13.3％) and transfusion rate(6.7％) were significantly lower than the control group(43.3％ ,33.3％) ,the difference was statistically significant(all P ＜0.01).ConclusionDelyed umbilical cord clamping in preterm children could increase the redblood cells and iron reserves in preterm children, reduce the incidence of anemia caused by blood transfusion, was worthy of clinical application.

Objective:To investigate the therapeutic effect of oat ?-glucans on serum lipid levels of rats with experimental hyperlipemia.Methods: Rats were fed on high fat forage for 3 weeks to establish hyperlipemia models,then the model rats were orally given oat ?-glucans at doses of 133,266 and 533 mg/(kg?d) separately.At the same time,there were 3 control groups including chitosan ligosaccharide[200 mg/(kg?d)],normal,and high blood lipid(model rats fed with distilled water).Serum levels of total cholesterol(TC),high density lipoprotein cholesterol(HDL-C) and low density lipoprotein cholesterol(LDL-C) were assayed in rats of all groups and the results were compared.Results: ?-glucans obviously decreased the levels of TC and LDL-C and increased HDL-C in rat hyperlipemia models.The reduction of serum lipid level in 4-week ?-glucans treatment rats was more obvious than that in 3-week ?-glucans treatment rats.Besides,?-glucans showed an obvious dosage dependent effect in reducing serum lipid level without adverse effect.Oat ?-glucans had a better lipid-reducing effect than ligosaccharide did.Conclusion: Oat ?-glucans can obviously decrease serum lipid in rats with hyperlipemia.

High myopia is a complicated disease as it resembles with primary open-angle glaucoma(POAG)in appearance of the fundus.To avoid making mistake,we would think much of similarities and differences between them.Modern equipments give large number of informations about the fundus,which predominate to establish the quantitative analysis when following up other than early diagnosis.Visual field analysis is interfered by HM fundus dystrophy,also relationship with study curve,long wave motion and short wave motion.It is very important in diagnosis and differential diagnosis with routine methods in clinical work.The experience and judgment of the doctors are never replaced by equipment as yet.

Bone tissue engineering is the focus of recent research. Its status quo and tendency are discussed from scaffold, cell and tissue reconstruction. Based on this analysis, we want to shorten the distance before it's clinical application and give some reasonable methods.

Thyroid associated ophthalmopathy (TAO) is often shown as upper eyelid retraction,conjunctival hyperemia and edema,proptosis,diplopia,strabismus and decreased visual acuity.It is difficult to make a certain diagnosis in the early stage of TAO.Patients suffering from TAO often have upper eyelid retraction at the early stage of disease,which affects appearance and causes feelings of discomfort and decreased visual acuity.Learning more about upper eyelid retraction contributes to the early diagnosis and treatment of TAO.Although upper eyelid retraction with TAO has distinctive manifestations,it is easy to misdiagnose.The differential diagnosis includes congenital eyelid retraction,neurological disorders,high axial myopia,glaucoma filtering bleb,and so on.Family history,clinical manifestations and TAO related examinations should also be taken into consideration.Comprehensive treatments should be adopted.Glucocorticoids and eyelid retraction surgeries are current mainstay of treatment.There are controversies on the application of glucocorticoids about the specific dosage,while agreement achieved that the cumulative dose should not be more than 8 g in one stage in order to reduce the risk of liver failure and other adverse events.Different operation methods should be chosen according to the degrees of retraction and causes of disease for each type of patients.In addition,special attentions should be paid to the decrease of muscle strength in the temporal side.Individual analysis is needed in order to diagnose and treat upper eyelid retraction with TAO.Early diagnosis and intervention can improve the appearance,visual function and quality of life of the patients.

Objective To study the clinical effect of diazepam and phenobarbital in children with febrile convulsion.Methods Seventy cases of febrile convulsion patients were divided into control group (phenobarbital treatment,35 cases) and experiment group (diazepam combined with phenobarbital,35 cases) by random digits table method,and compared the efficacy and complications.Results Two groups were cured within 1 h.The effective rate within 30 min in experiment group was significantly higher than that in control group [88.6％ (31/35) vs.74.3％ (26/35)] (P ＜ 0.05).The recurrent rate in experiment group was significantly lower than that in control group [2.9％ (1/35) vs.14.3％ (5/35)] (P ＜ 0.05).The complications had no statistically significant differences between two groups(P ＞ 0.05).Conclusions Diazepam combined with phenobarbital are very effective for children with febrile convulsion,can greatly improve clinical efficacy,decrease recurrent rate,and won't produce adverse reaction and complications,are the ideal treatment in the clinical treatment.
