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 alkaloids from C. saxicla were measured by the model of scavenging the stable DPPH radical, which showed a concentration dependent scavenging effect. Conclusion: Compounds 3, 5, 8, 11, and 16 are isolated from C. saxicola for the first time. Compounds 5 and 16 show the strong anti-oxidative activities.

ObjectiveTo analysis the clinical features of thoracic spine and spinal cord injury (SCI) and summarize the inclusive standard of cellular transplant clinical trial for SCI.MethodsThe data of 72 cases with thoracic spine and spinal cord injury from 1990 to 2005 were analyzed retrospectively.ResultsMean follow-up period was 20 months (6～48 months). There was no recovery in 12 spinal cord injury without radiographic abnormality (SCIWORA) patients, but improvement of urine function in 4 cases. 5 cases of 52 fracture-dislocation complete injury were improved to grade B (sense recovery), rate of recovery was 9.6%; recovery rate was 62.5% in incomplete injury. Sense recovery of all cases was better than motor recovery. Partial cases appeared spasm paralysis relief.ConclusionIncidence rate of complete injury is high and recovery is bad in thoracic spine and spinal cord injury. The inclusive standard of cellular transplant clinical trial for SCI is old complete thoracic spinal cord injury without residual compression.

AIM :To investigate the association of primary open-glaucoma (POAG), intraocular pressure (IOP) and systemic blood pressure in a rural population aged 50 years old or above in Shaanxi Province, China.METHODS: In the population-based, cross-sectional study, 1 775 (83.53%) residents, aged 50 years old or above, from 3 counties of Shaanxi Province, China, undertook an interview with a standard questionnaire and a detailed eye examination, including logarithm of the minimum angle of resolution visual acuity, slit-lamp biomicroscopy, applanation tonometry and dilated fundus examination. Two blood pressure reading in the sitting position were taken. Gonioscopy was performed if a narrower peripheral anterior chamber (less than one fourth of the corneal thickness) was indicated. Automated visual field testing was performed by participants assessed to have suspicion of glaucomatous disc damage or if IOP was 22mmHg or higher.RESULTS: IOP significantly correlated with systemic blood pressure, and both IOP and systolic blood pressure increased significantly with increasing age. No association between POAG and hypertension was found. The frequency of POAG increased significantly with lower diastolic perfusion pressure.CONCLUSION: Data in our study are accordance with those reported in other population-based studies, and confirm that lower diastolic perfusion pressure is a significant risk factor for primary open angle glaucoma.

AIM: To assess the prevalence and risk factors for age-related macular degeneration (AMD) in a rural population in Shaanxi Province of China.METHODS: A total of 2 835 (81.00%) people aged 40 years old or more, from Fuping county, Jingbian county and Yang county of Shaanxi Province, China, underwent a comprehensive interview and a relative eye examination. The present of AMD was classified into neovascular AMD (NV) and pure geographic atrophy (GA) by using direct ophthalmoscopy for fundus examination according to International Classification System.RESULTS: The prevalence (95% CI) of AMD was 3.00% (2.42, 3.71) in this population, of which NV accounted for 1.45% (1.05, 1.98) and 1.55% (1.14, 2.10)for GA. The prevalence of AMD increased significantly with increasing age (P ＜0.001). AMD was present in 0.47% of participants aged 40 to 49 years, rising to 11.90% of participants older than 80 years, of which the corresponding data increased from 0.28% to 4.76% for NV and from 0.19% to 7.14% for GA. No significant difference was found in the prevalence of NA and GA between genders in this population. With multiple logistic analyses, apart from advancing age, only smoking was found to have a strong association with any type of AMD.CONCLUSION: The prevalence of AMD in the rural population of Shaanxi Province of China is lower than that reported from other population-based studies in different provinces of China, less than that reported in whites, more than that reported in blacks. Except increasing age, smoking is also a significant well-known risk factor for AMD.

· AIM: To assess the prevalence and related risk factors for primary angle-closure glaucoma in a rural population for 40 years of age or older in Shaanxi Province.· METHODS: By using a stratified, cluster-based, random sampling technique, 8 500 persons of all ages were selected randomly, including 3 500 those aged 40 years or more, from the North, the South and the Middle of Shaanxi Province in Western China from July to December in 2003. All participants had an interview with a standard questionnaire and those questions related to glaucoma of previous diagnosis and treatment, family history and outbreak history. Then a detailed and relative eye examination was performed, including logarithm of the minimum angle of resolution visual acuity, external eye examination with slit-lamp biomicroscopy and fundus examination. The intraocular pressure was measured with Perkins applanation tonometry to those persons aged 50 years old or more and those with suspected increased IOP. A further examination was performed to those persons with suspicious glaucoma, including repeated tonometric examination, gonioscopy, dark room test, automated visual field testing, et al.·RESULTS: 6 815 of the eligible 8 500 persons of all ages were interviewed and examined from July to December in 2003, a response rate of 80.18%, including 2835 of the eligible 3 500 persons of 40 years old or more with a response rate of 81.00%. According to Van Herick method, the percentage of shallow peripheral anterior chamber was 13.6%, of which 10.4% was in grade 2, 3.0% in grade 1, and 0.2% in grade 0. In this rural population for 40 years of age or older 31 participants were found to have primary angle-closure glaucoma, with the prevalence of 1.09%. With multiple logistic analyses, the prevalence increased significantly with age (P=0.008), whereas no significant difference (Pgender=0.180, Peducation=0.199) was found in the rate with gender and education, although women and illiteracy seemed to be at increased risk of the disease (OR: 1.77, 95%CI,0.77-4.10; OR: 1.71, 95%CT, 0.76-3.87). Of 31 participants, 21 persons (67.74%) had not been previously diagnosed and treated. Of 10 participants previously diagnosed, 6 (60%) had been received peripheral iridectomy; nevertheless, no any other treatments were performed. 48.39% participants suffered from visual impairment in various degrees, of which the percentage of blindness in either eye accounted for 29.03%. Of those with primary angle-closure glaucoma, 22 persons (70.97%) were classified as having chronic from of the disease.· CONCLUSION: In this rural population in Shaanxi Province of China, the rate of occludable angles is 13.6%, more common than that reported previously in other Chinese populations. The prevalence of primary angle-closure glaucoma is close to that from other Asian populations, increasing with age. A majority of glaucoma was undiagnosed and untreated previously.

In those aged 30 years old or more, the prevalence of the disease was 0.23%, 0.28% and 0.39% for those more than 40 and 50 years old, respectively. The rate of suspicious POAG was 0.18% (12 cases) with age ranging from 35 to 77 years (mean year: 54.7). With multiple logistic analyses, the prevalence increased significantly with age (P=0.023). Other than increasing age, myopia was also a strong risk factor for POAG. Of 9participants with POAG, only 2 cases (22.22%) had been previously diagnosed. No one with POAG was received any treatment previously. 66.67% (6 cases) participants with POAG suffered from visual impairment in various degrees secondary to POAG. The percentage of blindness in either eye was 33.33%.· CONCLUSION: The prevalence of POAG is close to that from other Chinese populations, increasing with age. A majority of glaucoma was undiagnosed and untreated previously.
