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.

0.05).It was revealed that all the patients followed up 3 to 6 months after treatment were free from complaints of the involved teeth,with nomal food intake and mastication.No abnormal adjacent tissues of dental roots were detected by imaging examination.Conclusion For the vital teeth,the similar clinical effect may be obtained by one-visit RCT and multi-visit RCT.

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.

To observe the effect of Astragali Radix polysaccharides (APS) on the learning and memory functions of aged rats, in order to explore its mechanism for improving the learning and memory functions. Natural aging female SD rats were selected in the animal model and randomly divided into the control group, the APS low-dose group (50 mg x kg(-1)), the APS high-dose group (150 mg x kg(-1)) and the piracetam-treated group (560 mg x kg(-1)). They were orally administered with the corresponding drugs for consecutively 60 days. Besides, a young control group was set. The learning and memory functions of the rats were tested by the open-field test and the Morris water maze task. The Western-blot method was used to observe the levels of relevant neural plasticity protein N-methyl-D-aspartate receptor (NMDA receptor) in hippocampus, calcium/calmodulin dependent protein kinase II (CaMK II), protein kinase (PKA), the phosphorylation level of CAMP response element binding protein (CREB) and the protein expression of brain derived neurotrophic factor(BDNF). In this study, the authors found that the learning and memory functions and the hippocampus neural plasticity protein expression of the aged rat group were much lower than that of the young control group (P < 0.01). Compared with the aged rat group, the APS group showed the significant improvement in the impaired learning and memory functions of aged rats and the up-regulation in the hippocampus neural plasticity protein expression. The results showed that APS may improve the learning and memory functions of aged rats by increasing the expressions of relevant neural plasticity proteins.

OBJECTIVETo explore the clinical effects of minor bone anchors and palmaris longus tendon graft in treating chronic mallet fingers deformity.

METHODSFrom January 2008 to June 2013, 26 patients with chronic mallet fingers deformity were treated with minor bone anchors and palmaris longus tendon graft. There were 18 males and 8 females, aged from 18 to 52 years old with an average of (32.0±1.3) years. Among them, 8 cases caused by machine injury, 6 cases by fall injury, 6 cases by sprain from fight, 4 cases by tendon spontaneous rupture, 2 cases by knife trauma. There was no tendon attachment of extensor tendon check in 16 cases, and with 0.3 to 0.5 cm tendon attachment in 10 cases. All patients had the flexion deformity and the disability of dorsiflexion activity. During operation, the distal interphalangeal joint was fixed in 10° to 20° dorsiflexion by a Kirshner wire, the minor bone anchor was used to reconstruct the extensor tendon insertion, the palmaris longus tendon slice was transplanted the decayed area of extensor tendon insertion. Four weeks postoperatively, the Kirshner wire was removed and the plaster external fixation was used, and the patient began function exercises. Postoperative complications were observed and fingers functions were assessed according to Dargan standard.

RESULTSThe patients were followed up from 6 to 14 months with an average of (5.0±0.3) months. Wound superficial infection occurred in 2 cases, the skin pressure ulcer in 2 cases, joint activities disability in 1 case; these symptoms got improvement after symptomatic treatment. Traumatic arthritis occurred in 2 cases, 1 case was improved after treatment, and 1 case had chronic pain for a long time. No internal fixation loosening or breakage and tendon rupture were found. According to Dargan standard to evaluate the finger function, 17 cases got excellent results, 8 good, and 1 poor.

CONCLUSIONIt is an effective way to treat the chronic mallet finger deformity using minor bone anchors and palmaris longus tendon graft, and the method has advantages of reliable fixation, easy operation, satisfactory effect and less complication.
