3cm than in the patients with the largerest dominant diameter≤3cm.Embolization with combination of PLE and GSP had improved the percentage of reduc- tion in myomas volume.Conclusion The factors affecting results include tumor size and location,using of GSP,and performing of bilateral embolization.

In 1961,World Health Organization recommended that the concept of preterm birth is less than 37 weeks of gestation age newborn.The incidence of preterm birth has always been high and remains to be the leading cause of perinatal morbidity and mortality,despite the rapid development of global medical science level for decades.Studies on causes and mechanisms of preterm birth have become a hot spot worldwide.This paper is a summary analysis about the domestic and foreign research on preterm labor.The factors are divided into 5 broad,including categoriesmaternal factors,pregnancy factors,fetal factors,external factors and genetic factors,in order to popularize science of preterm birth and make for preterm birth prevention and clinical study.

With the neonatal intensive care techniques developing,the survival rate of preterm infants has increased markedly.However,these survival preterm infants are extremely vulnerable to develop various diseases,of which brain injury is the most important cause of the disability in preterm infants.At present,encephalopathy of prematurity,the incidence of which is rarely reported in domestic and national reports,mainly refers to white matter injury (WMI).This article reviews the different domestic and national reports about the incidence of encephalopathy of prematurity.

AIM: To investigate the effect of Guishen Capsule(Radix Angelicae Sinesis,Radix et Rhizoma Salivae Miltiorrhizae,etc) on mastoplasia and T-lymphocyte subsets of spleen in rats. METHODS: The model of mastoplasia was induced by benzoate estradiol intraperitoneal injection in SD female rats.The model rats were treated with low,middle and high dosages of Guishen Capsule,respectively.All rats were killed after 30 days,the tissue of second pair of mammary glands were observed.At the same time,the spleens were taken out for preparing single cells suspension.The ratio of CD~+_3,CD~+_4,CD~+_8,CD~+_4/CD~+_8 of splenic T-lymphocytes were determined by flow cytometry(FCM). RESULTS: Compared with normal group,the growth of weight was slow in model group,and its breast was swollen,and proliferation was obvious in mammary gland tissue,the ratio of CD~+_3,CD~+_4,CD~+_4/CD~+_8 reduced significantly in model group. Guishen Capsule could inhibit the breast swelling and mammary gland hyperplasia.It also could increase ratio CD~+_3,CD~+_4,CD~+_4/CD~+_8 of splenic T-lymphocytes remarkably. CONCLUSION: Guishen Capsule can inhibit mammary gland hyperplasia.It also has the function of immunologic enhancement and cellular immune regulation.

0.97).The method of Real-time PCR and molecular beacon detection for bifodobacteria has many advantages,such as being sensitive,specific,simple and fast,and this method can be used in situ detection of bifidobacteria quantitatively.

BACKGROUND:Bone mass deficiency is common during implantation in the maxil ary posterior region. Some patients do not want to accept extra surgery for increasing bone because of surgical trauma or medical expenses. Technology of the tilted implant has been proposed, but it has not been recognized and has a lack of relevant evidence.
OBJECTIVE:To investigate the stress distribution of per-implant bone which is subjected to different loading conditions when the different abutment angulations are applied, and to analyze the safety factor of different implants to verify the feasibility of the tilted implant in the maxil ary posterior region.
METHODS:The finite element models of the different angulate abutments were established in commercial software packages. The safety factor of implant in the same power load was observed, and stress and strain condition of the implant and the surrounding bone was also observed.
RESULTS AND CONCLUSION:With the increased abutment angulation, the maximum strain of pre-implant bone was significantly increased, and the safety factor of implant decreased gradual y. Thus, the tilted implant is not recommended in the maxil ary posterior region.

?AIM:To investigate the causes and characteristics of retinal detachment after vitrectomy.?METHODS: Retrospective analysis of patients in our hospital in recent 4a who underwent primary, standard, three -port pars plana vitrectomy ( PPV ) . Retinal detachment occurred in 24 eyes ( 23 cases ) , 24-67 years old, average 49.0±12.0 years old.There were male in 17 cases, female in 6 cases, 6 right eyes, 18 left eyes.?RESULTS:Eighteen (75%) eyes without any symptoms were found during a routine check, 6 eyes ( 25%) with decreased visual acuity or in front of shadow.It took 1-223d from PPV to retinal detachment, average 40.7 ± 54.2d, of which retinal detachment occurred in 10 (42%) eyes within 1wk, 14 (58%) eyes within 1mo.The direct cause of retinal detachment was new retinal break ( a total of 27 holes ) in 19 eyes, proliferative vitreoretinopathy ( PVR) in 4 eyes, 1 eyes with primary hole not closed.All retinal detachment were ultimately completely reset.?CONCLUSION: The occurrence of new retinal breaks is the main cause of retinal detachment after vitrectomy, attention should be paid to the early postoperative peripheral retinal examination;after a timely surgery, the retina can be reset.

In the course of dissection the authors revealed several—from 2 to 8—perforating branches in the peroneal artery instead of only 1 as stated in the text-books. These branches,after perforating the interosseous membrane, supplied the extensor muscles of the leg and might form anastomosis with the anterior tibial artery.On the other hand,the anterior tibial artery was also found to send twigs to perforate the interosseous membrane, anastomosing with the peroneal artery or supplying the muscles of the back of the leg. These communications might be explained by the change in the course of the arteries of the leg during embryonic development.Any failure in the disappearance of the horizontal communications between the embryonic longitudinal vessels would result in a feature as found by the authors.
