1.The development of recombinant factor Ⅷ concentrates for clinical application
International Journal of Pediatrics 2011;38(6):548-550
Replacement therapy with plasma derived or recombinant F Ⅷ (rFⅧ) concentrates is only effective way to treat hemophilia A.Currently,the first,second and third generation rFⅧ are commercially available.Of the three products,the third generation rFⅧ products are best,because of no additional human or animal plasma proteins at any period.The use of rFⅧ concentrates has greatly improved the safety of replacement therapy in hemophilia A and reduced the risk of blood-borne pathogen transmission.In this article we review the current knowledge about the three rF Ⅷ concentrates,analyzing their main characteristic and their clinical hemostatic efficacy and safety.

OBJECTIVETo search for an optimal protocol and freezing conditions for the cryopreservation of microamount round spermatids of the mouse.
METHODSWe compared the survival rates of frozen-thawed microamount round spermatids of the mouse achieved by vitrification or standard slow freezing with different concentrations of glycerol (5, 7, or 9%) and different lengths of equilibrium time (0, 15, 30, 45, or 60 min).
RESULTSUnder the conditions of 7% glycerol and 30 min equilibrium, both vitrification and standard slow freezing achieved high survival rates of spermatids, and the former obtained an even higher rate than the latter ([72.9 ± 15.4]% vs [58.2 ± 17.7]%, P < 0.05).
CONCLUSIONA high rate of frozen-thawed microamount round spermatids of the mouse can be achieved by vitrification under the conditions of 7% glycerol and 30 min equilibrium.

Objective To study the relationship among insulin-like growth factor 1 (IGF-1), insulin-like growth factor binding protein 3(IGFBP-3) and birth weight, length and placental weight and to discuss the endocrine factors which affected fetal growth by assaying levels of IGF-1、IGFBP-3 in umbilical cord serum.Methods The neonates were divided into appropriate for gestational age infant(AGA) and small for gestational age infant(SGA) according to birth weight and gestation. The birth weight, length and placental weight of neonates were measured and at meantime the levels of IGF-1 and IGFBP-3 were assayed by immunoradiometric assay.Results 1.There were 105 neonates, including 79 AGA and 26 SGA. There were significantly statistical differences in birth weight, length and placental weight (all, P

Objective To study the clinical significance of dynamic determination of serum CRP,IL-6 and fibrinogen(Fib) levels in unstable angina pectoris (UAP) patients.Methods 162 UAP patients were selected as UAP group(including 52 cases of low risk group,53 cases in medium risk group and 57 cases in high risk group),58 healthy people were selected as control group.The CRP,IL-6 and Fib contents were observed in UAP patients after cardiac events.Results At discharge,CRP,IL-6,Fib in UAP low risk group were (3.47 ±0.55)mg/L,(10.38 ± 1.57) ng/L,(1.64 ± 0.65) g/L,which were significantly lower than the admission contents [(6.50 ±0.87) mg/L,(14.35 ± 1.22) ng/L,(3.01 ± 0.28) g/L] (t =2.761,2.945,2.118,P =0.028,0.003,0.031).CRP,IL-6,Fib levels in the medium risk group were (6.87±0.75) mg/L,(14.35 ± 1.02) ng/L,(2.26 ± 0.33) g/L,which were significantly lower than the admission contents [(9.21±1.03) mg/L,(19.24±1.58) ng/L,(4.15 ±0.47) g/L] (t =2.985,3.157,3.548,P =0.003,0.001,0.000).CRP,IL-6,Fib levels in the high risk group were (8.71 ±0.84) mg/L,(17.37 ± 1.26) ng/L,(4.67 ±0.85) g/L,which were significantly lower than the admission contents [(12.48 ± 1.24) mg/L,(25.13 ± 1.84) ng/L,(7.28 ± 0.64) g/L] (t =3.472,4.018,5.097,P =0.000,0.000,0.000).Six months after hospital discharge,in CRP,IL-6,Fib elevated groups,the incidence rates of cardiac event were 40.20%,40.35% and 47.50%,which were significantly higher than those in normal group (5.0%,4.17%,14.29%,x2 =23.655,2.211,14.442,P=0.000,0.000,0.000).Conclusion CRP,IL-6 and Fib levels in UAP patients were significantly higher than those in healthy people,and with remission,contents would be lower,which was the index to reflect the severity of UAP,but its specificity is bad,need to use caution.

Chinese Journal of Medical Education Research 2013;(3):312-314
The definition of rehabilitation should reflect the connotation and extension of rehabilitation medicine system,moreover,special attention should be paid to the process of translation,applications and promotion due to its derivation from Latin.The fourth edition of rehabilitation medicine textbook which published by People's Medical Publishing House described the definition of rehabilitation inaccurately,although integrated the foreign authority definitions.The definition of ‘ re-learning’has been described by the textbook without considering logical sequence,which caused difficulty in explaining and comprehending between teachers and students in class.Besides,application of another term of rehabilitation medicine in the textbook is imprudence.

Objective To evaluate improvement of visual acuity for advanced proliferative diabetic retinopathy eyes with different complications after vitrectomy. Methods Four groups of advanced proliferative diabetic retinopathy (APDR) in 314 eyes with diabetes type Ⅱ and type Ⅰ were analyzed retrospectively: vitreous hemorrhage with limited traction retinal detachment (VH), extensive fibrovascular membranes with traction retinal detachment (TD), combined rhegmatogenous and traction retinal detachment (CRT) and cataract with vitreous hemorrhage or and traction retinal detachment (CHD). Results 0.1 or better postoperative visual acuity was achieved in 59.5% of type Ⅱ and 66.7% of type Ⅰ in the VH group; 39.4% of type Ⅱ and 52.6% of type Ⅰ in the extensive TD group; 31.6% of the CRT group; 62.5% of the CHD group. The major intraoperative complication is iatrogenic retinal breaks. The causes of postoperative visual loss in present study included neovascular glaucoma (2.8% of type Ⅰ and 0.4% of type Ⅱ in aphakia, 25% of type Ⅱ in aphakia and 4.2% in pseudophakia), retinal detachment and CRAO. Conclusion The majority of APDR eyes obtained better visual improvement after vitrectomy and photocoagulation.

Objective To evaluate the success rate and the risk of impairing vision for epimacular surgery. Methods A retrospective analysis of 57 eyes with epimacular membrane after surgery was made, and the changes in visual acuity and near visual acuity, in different etiology, improvement in distortion, as well as intraoperative and postoperative complications were compared. Results The eyes of 78 8% achieved a visual improvement of more than 2 lines. The visual improvement after surgery of epimacular membranes was the most in buckling group, then in macular hole with epimacular membrane and idiopathic eyes, the change was very limited in macular traction syndrome. The improvement of near visual acuity is usually better than distant visual acuity. The improvement rate of distortion is of 65 0%. The main intraoperative complication was reopen of the primary hole(4 eyes) and the formation of new hole(5 eyes). Conclusion Surgical peeling for epimacular membranes can improve the visual acuity and distorted vision,particularly in epimacular membrane after buckling surgeries, with macular hole and idiopathic eyes. possible risks might be present in surgical manipulation.
