Objective: To observe the efficacy of contralateral needling combined with Maitland ankle mobilization in the treatment of chronic ankle sprain.Methods: A total of 106 patients with chronic ankle sprain were included in the study. They were numbered according to their order of visit, with odd numbers assigned to the control group and even numbers assigned to the observation group, with 53 cases in each group. Patients in the control group were treated with Maitland ankle mobilization, while those in the observation group were given additional contralateral needling treatment. After treatment, we observed the indicators including, ankle circumference, range of motion (ROM) of dorsiflexion, ROM of plantar flexion, thickness of ankle ligaments, and the changes in Baird-Jackson ankle score, American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score, and visual analog scale (VAS) score to compare the efficacy between the two groups. Results: After treatment, the total effective rate of the observation group was 94.3％ and was significantly higher than that of the control group (81.1％), indicating statistical significance (P<0.05). After treatment, the ankle circumference of both groups decreased, and the ROM of dorsiflexion and the ROM of plantar flexion increased (P<0.05). The changes in the observation group were more significant, indicating inter-group statistical significance (P<0.05). After treatment, the thickness of the anterior talofibular ligament, calcaneofibular ligament, and posterior talofibular ligament, as well as the VAS scores decreased in both groups; the changes in the observation group were more significant, indicating inter-group statistical significance (P<0.05). After treatment, the Baird-Jackson ankle score and the AOFAS ankle- hindfoot score increased in both groups, and the scores in the observation group were higher than those in the control group, indicating inter-group statistical significance (P<0.05). Conclusion: The efficacy of contralateral needling combined with Maitland ankle mobilization in the treatment of chronic ankle sprain is superior to that of Maitland ankle mobilization alone.

Objective To investigate the effect of natural killer (NK) cells treated by serum of severe preeclampsia patient on the function of endothelial cells.Methods Fifteen patients with severe preeclampsia and 15 normal pregnant women from the Obstetrics department,Shengjing Hospital,China Medical University were admitted into this case-control study from January 1,2006 to December 31,2008.NK cells from healthy non-pregnant woman were incubated with 20% serum from severe preeclampsia patients or normal pregnant women for 20 hours.Then,human umbilical vein endothelial cells ( HUVEC) and serum-treated NK cells were co-incubated for 24 hours.Apoptosis of HUVEC was checked by flow cytometry and electronic microscope.Endothelin-1 (ET-1) levels in the supernatants of HUVEC and NK cells were examined by radioimmunologic method.Results In severe preeclampsia group,the percentage of early apoptosis cell (Annexin V-FITC+ /PI+ ) was (23.81±4.79)%,that of late apoptosis cell (AnnexinV-FITC+/PI+ ) was (3.29±1.04) %,while those were (16.59±5.13)% and (2.24±0.72)% respectively in normal pregnant group (P＜0.01).There was no significant difference in dead cells (Annexin V-FITC- /PI+ ).Under electronic microscope,typical morphologic changes of apoptosis were shown in severe preeclampsia group.Level of ET-1 in

BACKGROUND: To search for an alloxenogeneic bone with good load bearing function and osteoblastic activity for treating bone defects is an important study issue. We have made a comparative study on its biome chanical characteristics and found that there was no significant difference in maximum load stress, maximum pressure as compared with fresh bone of the same size. Clinicians are concerned about the osteoblastic activity and whether the osteoblastic activity can be reserved after human allogenous a cellular bone (HAB) loaded with bone marrow stromal cells (BMSCs). OBJECTIVE: To investigate the experimental effect of HAB loaded with induced BMSCs, and observe the cellular adherence and growth as well as detect its osteoblastic activity. DESIGN: Single sample experiment. SETTING: Second Affiliated Hospital of Harbin Medical University. MATERIALS: This experiment was conducted at the Experimental Center of the Second Affiliated Hospital of Harbin Medical University between January 2003 and August 2004. HAB was obtained from fresh corpse iliac bones (donated voluntarily). METHODS: Connective tissues and cell compounds of the iliac bones were removed by processing with hydroperoxide andether solution and sterilized for preparing HAB. BMSCs from living femoral shaft bone marrow were cultured immediately in ordinary and mineralized medium containing DMEM, fetal bovine serum, dexomethasone, β-glycerophophate and ascor bic acid. Proliferation and differentiation of bone stromal cells were deter mined by detecting the level of alkaline phosphatase (ALP) and osteocalcin (OCN) in the culture medium. Induced bone stromal cells solution was condensed and implanted within HAB scaffold. Cellular osteoblastic activ ity was determined through morphological observation under the light mi croscope and electron microscope as well as biochemical index detection. MAIN OUTCOME MEASURES: ① Detection results of ALP and OCN of BMSCs/HAB composite. ② Histological observation results of BMSCs/ HAB composite. RESULTS: ① Iliac bone block cells were cleaned with good reservation of bone matrix. ② The level of ALP and OCN of MSCs was higher after in ducing for 8 days than that in control group [MSCs after induction: (181.54±40.01) nkat/L, (7.2±1.3) μg/L. There was no method to detect the level in control group, P ＜ 0.05]. ③ BMSCs were adhered and grew well in HAB scaffold. CONCLUSION: HAB loaded with induced BMSCs has an excellent os teogenic function in vitro and shows an effective potential as a good bone tissue engineering material.

Objective To discuss the surgical method of resection of petroclival tumors used temporal base transtentorial approach.Methods Analyzed 26 cases of petroclival tumors.All of them were surgically treated under intraoperative neurophysiological monitoring by temporal base transtentorial approach.Firstly the supratentorial part of tumors were resected by pieces,and then the tentorium was cut open,in order to resect residue of the subtentorial part of tumors.This surgical maneuver was applied to reduce the retraction to surrounding vessels,nerves and brain stem,as well to protect important structures and to finally achieve radical removal of the tumors.The efficacy and complications were observed.Results Among 26 cases,19 cases (73.1％,19/26) achieved total removal,5 cases (19.2 ％,5/26) achieved subtotal removal and 2 cases (7.7％,2/26) achieved great partial removal.There was no surgery-related death.Eleven cases suffered from partial neurological deficit.All cases were followed up for 3 months to 4 years,3 cases underwent complete recovery,4 cases underwent partial recovery,and 4 cases underwent permanent deficit.Conclusions Using temporal base transtentorial approach to resect petroclival tumors is convenient,applicable,safe and with minimal injury and with high proportionality of total resection.Under intraoperative neurophysiological monitoring,this approach may be an ideal choice for surgical treatment of these tumors.

Objective To analyze MRI appearance after augmentation mammoplasty,and to assess the clinical value.Methods Sixty-three cases with augmentation mammoplasty were imaged by MR scanner.MR imaging features of silicone implant and injected implant were analyzed respectively.Results(80 breasts) in 40 patients were with polyacrylamide hydrogel injection.In 50 breasts,the implants were shown as irregular gel in mammary gland,pectoralis muscle,and subcutaneous tissue.Auto-fat injection in both side of breast was performed in 7 cases.Among them,fibrofatty mass was detected in 12 breasts,fat-fluid interface was seen in 6 breasts,and fat in pectoralis major was revealed in 6 breasts.Silicone implant in both side of breast was performed in 16 cases.2 breasts in 2 case were detected as saline-filled implants with intracapsular rupture.14 cases were with silicone gel-filled implants,among them,4 breasts were found to have extracapsular rupture and 10 breasts intracapsular rupture.Conclusion MRI is a perfect method in accessing the patients with augmentation mammoplasty.

Objective To explore the effect of collagen membrane combined with recombinant human bone morphogenetic protein-2(rhBMP-2) on periodontal tissue regeneration and repair in periodontal defect models of rats.Methods Eighteen male healthy Wistar rats,which were made experimental periodontal bone defects in the inferior incisors,were randomly divided into three groups:control group,collagen membrane group(Co),collagen membrane and rhBMP-2 group(Co/rhBMP-2).Two rats from each group were sacrificed at 4,6,8 weeks after operation.The mandibles were removed,and examined under light microscope.Results In Co/rhBMP-2 group: 4 weeks after operation,a large amount of bone formed in the defects;6 weeks later,new bone filled in the defects;8 weeks later,alveolar bone emerged,newly-formed periodontal ligament and cementum localized at the root edges,no gingival epithelium was observed.In Co group:4 weeks after operation,new bone formed at the edge of the defects;6 weeks later,a larger amount of bone and periost were observed;8 weeks later,a small amount of periodontal ligament and cementum localized at the root edges.In control group: 4 weeks after operation,there was a small amount of newly-formed bone at the edge of the defects;6 weeks later,collagen fibers were found at the edge of defects;8 weeks later,a small amount of periodontal tissue reached its original height and gingival epithelium proliferated obviously.Conclusion Collagen membrane combined with rhBMP-2 which has not only conductive effect but also effect of osteoinduction,can prevent the long-epithelium growing,maintain the growth gap,and promote periodontal tissue to regenerate.

Background and purpose: Cervical nodal metastasis in nasopharyngeal carcinoma plays an important role in the definition of radiotherapy area and clinical staging, it is also one of the main factors influencing prognosis. So this study was designed to explore the pattern of metastatic lymph nodes for patients with nasopharyngeal carcinoma, which may provide a basis for clinical treatment and research. Methods: From Jun. 2005 to Sep. 2007,779 histologically diagnosed nasopharyngeal carcinoma patients had routine MRI scan before radiation therapy at Fujian Provincial Cancer Hospital. Diagnostic radiologists and radiation oncoiogists together assessed the nodal distribution according to the guideline CT-hased delineation of lymph node levels. Then, Chi-sqnare test was used to analyze the correlation between T stage and nodal metastasis rate and between nodal diameter and nodal extracapsular invasion. Results: Of 779 patients, 592(76.0%) had nodal involvement. The distribution was as follows: 1 in level Ⅰ,384 in level Ⅱa, 499 in level Ⅱ_b, 184 in level Ⅲ, 33 in level Ⅳ, 67 in level V_a, 21 in level V_b, 597 in retropharynx.In these patients, a total of 1 479 postive nodes, including 973 (65.79%) extracapsular spread nodes, were detected.The rate of nodal extracapsular invasion was higher when the axial diameter increased. Leap metastasis rate was 1.0%. No significant correlation was found between T stage and nodal involvement. Conclusion: The level Ⅱ and retropharyngeal node were the most frequently involved regions, they had similar metastatic rate and were both the first echo node to metastases of nasopharyngeal carcinoma. Level Ⅰ metastasis was lower. The proportion of extracapsular spread of metastatic lymph nodes increased with axial diameter of lymph nodes-dependent. The cervical node involvement of nasopharyngeal carcinoma was spread orderly down the neck, and the incidence of skip metastasis is rare. The relationship between T stage and nodal involvement has no statistical significance.

Objective To observe the effect of transplanting the adipose-dervived stem cells(ADSCs) on free radical metabolism and immune function of rat aging model induced by D-galactose from fasiaology perspective;to explore a new method for anti-aging. Methods The ADSCs were cultured in vitro. Thirty male SD rats were randomly divided into 3 groups: normal control group(A), aging model group(B) and treat group(C). Ten rats in each group. Rats in B and C groups were injected D-galactose continually into make the sub-acute aging model rats.After 8-week injections of D-galactose;R3ats in group C were injected ADSCs(3×10~6/ml) through caudal vein. After 2-week transplantions of ADSCs, T-SOD, CuZn-SOD, MDA, NO, IL-2 and spleen index levels in serums of each group were detected and compared among the three groups. Results Compared with the A group, the SOD, NO, IL-2 level and spleen index in serum in group B decreased significantly, while the contents of MDA increased significantly. Compared with group B, the SOD, NO, IL-2 level and spleen index in serum in group C had been improved, and the contents of MDA decreased significantly. Conclusion Transplanting ADSCs can improve the antioxidant ability and strengthen the cellular immune function of aging rats.Further more, it can delay the ageing procedure induced by D-galactose in rats.
