Objective To evaluate the clinical results of flexor hallucis longus (FHL) tendon transfer in treatment of patients with Achilles tendon defects of more than 6 cm. Methods Between January 2005 to February 2009, 19 patients with Achilles tendon defects, 13 males and 6 females, were treated with FHL tendon transfer. Their ages ranged from 20 to 61 years, with an average of (42. 6 ± 8.2)years. Fifteen defects were found during tendonitis debridement, and 4 were old ruptures. Time from rupture to surgery ranged from 0 to 6 months (average, 2.6 months). Defects were 6 cm to 10 cm long. Procedures were performed in a two-incision manner. The postoperative ROM of ankle joint, American Orthopaedic Foot and Ankle Society(AOFAS) and visual analogue scale(VAS) scores were recorded at 3 months, 12 months,and the last follow-up. The results were statistically analyzed to evaluate the functional recovery. Results Follow-ups lasted from 12 to 48 months (average, 22. 2 months). At the last follow-up, the average ROM of ankle joint was 17.8°± 1.9° at dorsal flexion and 39.1°±2.3° at plantar flexion, and the last average AOFAS score was up to (91.8 ± 1.7), significantly different from those at 3 months after surgery (P＜0.05), but not significantly different from those at 12 months (P＞0.05). The difference were significant between the results of 3 months and 12 months (P＜0.05). The last average VAS score was (1.0±0.7),significantly different from those at 3 months and 12 months(P＜0.05) . There was also significant differences between the VAS scores of 3 months and 12 months (P＜0.05). Patient's satisfaction was 100%.Conclusion FHL tendon transfer is an efficient procedure for long Achilles tendon ruptures associated with tendonitis in relieving pain and maintaining the function of ankle joint.

Objective To evaluate the foot function after Lisfranc injury with local soft tissue in-jury. Methods From November 2000 to April 2006, 43 patients (at mean age of 32 years) with fresh Lisfranc injuries (45 sides) were managed with open reduction and internal fixation with screws, Kir-schner wires and AO plates. All patients had no joint surface damage and received no fusion surgery. Ac-cording to the Quenu-Kuss classification of Lisfranc injury, there were 14 patients with type-A injury, 21 with type-B and 10 with type-C. According to AO classification, there were 29 feet without severe soft tis-sue injury and 16 feet with severe soft tissue injury, of which 10 patients were combined with severe local soft tissue injury (one patient with Foot compartment syndrome). The period from injury to surgery was seven days. All patients received cast immobilization for 8-12 weeks and the foot function was evaluated by anteroposterior and lateral X-rays and American Orthopedic Foot and Ankle Society (AOFAS) score. Results All patients were followed up for 12-69 months (average 37 months), which showed that all pa-tients obtained anatomic reduction and 32 patients were satisfied with operative outcome. The average postoperative AOFAS score was 97 points for patients without severe soft tissue injury and 82 points for pa-tients with severe soft tissue injury (P<0.05). Conclusion After Lisfranc injury, the foot function is related to severity of both joint injury and local soft tissue injury.

The contents of coumarins in the sulfur fumigated Angelicae Dahuricae Radix (Baizhi, ADR) were reduced significantly. To achieve the quality control of ADR, the qualitative identification of sulfur fumigated ADR and quantitative model of imperatorin content should be established. The near-infrared (NIR) spectrograms of non-sulfur and sulfur fumigated ADR were collected by NIR diffuse reflectance spectroscopy technology and pretreated by the method of first derivative derivation and vector normalization. The Ward's Algorithm method was used for the cluster analysis. The non-sulfur and sulfur fumigated ADR can be quickly identified in the range of 8,806. 0-3 811.0 cm(-1) based on the cluster analysis. The NIR quantitative model of imperatorin was established by the contents of imperatorin determined by HPLC in combination with partial least squares regression analysis. According to the calibration model established in this study, correlation coefficients (R2), the root-mean-square error of cross-validation (RMSECV), and the root-mean-square error of prediction (RMSEP) for imperatorin were 0.982 8, 0.006 8, 0.011 8, respectively. The quantitative model of imperatorin can be applied to determine the content of imperatorin in ADR accurately.

The preterm birth has been increasing for the last decade. With the development of neonatal intensive care techniques, the survival rate of preterm infants is increased markedly. However, the brain of preterm infants is so vulnerable to injury that preterm brain injury has become an enormous public health problem. Hypoxia-ischemia and infection/inflammation are two main perinatal risk factors causing premyelinating oligodendrocyte and cortical neuron injury. Encephalopathy of prematurity is characterized by diffuse white matter injury and neuronal/axonal disruption, leading to neurological disabilities such as cognitive impairment and cerebral palsy. The advancement in imaging techniques, especially magnetic resonance imaging, provides more information for preterm brain injury and brain development, which contributes to the diagnosis and follow-up of the preterm infants. This article reviews the progress in encephalopathy of prematurity in order to open a new window to prophylaxis and management of this disease.

Heat shock protein 27 ( HSP27 ) is an endogenous protein that plays an important role in a great variety of physio-logical and pathological processes. It can express a large number under body stress conditions. Recent studies have shown estro-gen upregulates the expression of HSP27 through a number of ways, playing a perfect “triple protection” role. In the early stage of atherosclerosis, estrogen induces the phosphorylation of HSP27 via PI3K/Akt signaling pathway. Phosphorylation of HSP27 can resist the injury of vascular endothelial cells( VECs) through an antioxidant and anti-apoptotic pathway as well as the inhibition of cytochrome C. In the stage of forming foam cells, estrogen induces the expression and release of HSP27 from mac-rophages by stimulating the estrogen receptor β ( ERβ) , then HSP27 inhibits the LDL uptake and the release of proinflammato-ry cytokine by binding scavenger receptor A ( SR-A) . During the proliferation and migration of vascular smooth muscle cells ( VSMCs) , estrogen induces estrogen receptor α ( ERα) and protein phosphatase 2 ( PP2A) to form a complex that enhances the activity of PP2A, then it can lead to the dephosphorylation of HSP27 and finally inhibit cells proliferation and migration. In summary, the anti-atherosclerotic effect of estrogen is closely re-lated to the role of HSP27. Given the side effects of estrogen re-placement therapy( MHT) , regulating HSP27 may provide a no-vel therapy for the prevention and treatment of cardiovascular dis-eases in menopausal women clinically.
