This article is based on the searching from the United States Library of Congress Web Search science 2005 for the literature on the birth femoral fractures,reviewing its incidence,pathogenesis and treatment of such fractures of the latest developments,for the purpose of the provision of orthopedic and obstetric physician reference.Literature showed that neonatal birth femoral fractures might occur whether deli-veries were through the birth canal or by cesarean section.Whenever faced with fetal asphyxia,intracranial hemorrhage,such as critical state,it is critical to save the life of fetal babies,regardless of treatment.The prognosis of neonatal femoral shaft fractures is normally good without deformity left.

Due to substantial morbidity and high complications, diabetes mellitus is considered as the third "killer" in the world. Medicinal fungal polysaccharides, as water-soluble macromolecular substances with low toxicity, exhibit diversified pharmacological actions such as immune regulation, anti-tumor, antivirus, antioxidant, anti-aging, hypoglycemic effect and improving liver and kidney function. In recent year, a number of investigators reported medicinal fungal polysaccharides showed good anti-diabetes and hypoglycemic activity, and their acting mechanisms involved in glycometabolism and β cell function, e. g. promoting glycogen synthesis, promoting glycolysis, inhibiting the activity of α-glucosidase, promoting insulin secretion, increasing insulin sensitivity, enhancing antioxidation. Therefore, the hypoglycemic activity and its mechanisms of action of medicinal fungal polysaccharides showed characteristics of multiple effects, multi-target, and multi-pathway regulation. These finding suggest that medicinal fungal polysaccharides are a promising source for the development of discovery of anti-diabetic agent.

The plastic splint PCL,which is introduced in this article,is a new type of medical exter- nal immobilization material.During the course of its development,the burden has been optimality seeked with regressive orthogonality after screening of the material.Its function has attained the international levels during the eighties.This splint may be used not only in the treatment of burns and various orthopedic conditions,but also in the immobilization of fracture and rehabilation treatment of orthopedic patients etc.

More than ten bacteriophage of E.coli were isolated from the soil and the dung of the fowl-run, then three of named bacteriophage A, C, D which lysis E.coli virulently were selected to investigate biological characterizations. The results showed that high activities were obtained after the phages incubated at 50℃ for 1 h or 60℃ for 30 min. The phages could be alive at the range of pH from 4 to 12, Ca 2+ or Mg 2+ added to the medium could stimulate the lysis of phages. However, the formation of the plaque could be inhibited obviously by adding sodium citrate to the medium.

ObjectiveTo explore clinical features of cerebral palsy of premature infants and attempt to deduce the etiology and time of brain damages.MethodsMaterials included perinatal risk factors, neurodevelopmental evaluation, types of cerebral palsy and CT or MRI findings of 281 cerebral palsied children embryo age less than 37 weeks were analyzed retrospectively.ResultsAmong 281 cases, 47.07% of them were premature infants and most of them (64.67%) suffered from multiple high risk factors especially during perinatal and post neonatal periods. The main causes were perinatal asphyxia, icterus, and twin pregnancy. Spastic diplegia was more common in this group (70.81%), followed by athetosis and mixed of spastic and athetosis. The characteristic of neuroimaging findings was periventricular leukomalacia (PVL).ConclusionFor cerebral palsy of premature children, pematurity is an important cause of cerebral palsy and brain damages are often occurred during perinatal and post neonatal periods, main type is spastic diplegia, and main pathological change is PVL.

Euphorbia kansui (EK) is a toxic herbal drug, and often used after vinegar-processing to reduce its toxicity. In present study, a 1H-NMR based metabonomic approach was used to evaluate the detoxification effect of vinegar-processed EK. The water extracts of EK and VEK were administered orally to male SD rats at doses of 9 g x kg(-1) x d(-1) for 1 week, respectively, and one more week observation was further conducted. The control group was orally given with saline. Histopathological studies of liver samples on the 8th and 15th day were conducted, and the metabolites of rat urine and liver were analysed by 1H-NMR. Histopathological studies of liver samples from EK and VEK treated rats showed no negative impacts. In metabonomic analyses of urines, changes of metabolites indicated liver damages, kidney lesions and imbalance of gut microbes in the second week. VEK-treated rats showed a quite lower toxicity compared with EK-treated ones. The present study revealed that the metabonomic approach might be helpful for the evaluation of toxicity of EK and detoxic effect of VEK.

Background The pathological foundation of diabetic retinopathy is the breakdown of the bloodretina barrier induced by multifactors.Objective This study was to investigate the retinal morphologic change and the levels of serum vascular endothelial growth factor(VEGF),endothelin(ET)and nitric oxide(NO)in diabetic rats.Methods Forty healthy female SD rats were randomly divided into experimental group and control group and 20 rats for each group.Acute diabetes models were established by the intraperitoneal injection of 60 mg/kg streptozotocin in experimental group and the equal volume of buffer solution was injected at the same way in the control group.The serum VEGF level,ET level and NO concentration of diabetic and control rats were detected using ELISA double antibody sandwich method,125I radioimmune method and nitrate reduction method respectively at 2,4,6 and 8 weeks after injection.The eyeballs of rats were enucleated at the eighth week for retinal pathologic examination.This experiment followed the Measures for the administration of experimental animals of Shanghai City.Results The retinal structure was normal throughout the experimental duration in the control group.However,retinal edema and cellular disorganization appeared at 4 months and retinal blooding could be seen with the extending of diabetes course.The levels of serum VEGF and ET in each experimental group were significantly higher than those in control groups(P＜0.05).The levels of serum NO elevated in 2-month experimental group compared with same-phase control group(Z =-2.193,P＜0.05),and those in 6-and 8-month experimental groups were significantly lower than in corresponding control groups(Z =-2.449,Z =-2.236,P＜0.05).With the progression of the disease,the levels of VEGF and ET increased gradually,but the levels of NO decreased gradually,showing statistically significant differences(P＜0.05).The level of serum VEGF showed a positive correlation with serum ET level and a negative correlation with the serum NO concentration(r=-0.814,r=-0.803,P＜0.01)in the experimental group.A negative leaner relation was also found between serum ET level and serum NO concentration(r=0.821,P＜0.01).Conclusions The serum VEGF,ET and NO levels are closely associated with the degree of retinal lesion in early diabetic models.These results suggest that serum VEGF,ET and NO levels may be the important indexes predicting the course of retinal disease in diabetic rats.
