Objective Video-assisted thoracoscopic surgery is widely used in clinical practice,due to the characteristics of minimal invasion,quick recovery,low incidence of postoperative chest pain and the same effect of lobectomy as thoracotomy.However,the surgical itself has a certain degree of difficulty,and due to the effect of lymph node,intraoperative blood loss,pleural adhesions,conversion to thoracotomy surgery is needed in some cases. Understanding the risk factors of conversion to thoracotomy can help thoracic surgeons figure out the right time to operate the surgery.

Objective To investigate the clinical efficacy of acupuncture at point Houxi (SI3) in treating cervical spondylotic vertebral arteriopathy. Method Three hundred and fourteen patients with cervical spondylotic vertebral arteriopathy were randomly allocated to a treatment group of 158 cases and a control group of 156 cases. The treatment group received acupuncture at points Houxi, Fengchi (GB20), Wangu (GB12), Tianzhu (BL10) and cervical Huatuo jiaji (Ex-B2) points and the control group, no acupuncture at point Houxi. The therapeutic effects were evaluated in the two groups after treatment. The recurrence rates were compared at the one-year follow-up. Result The total efficacy rate was 94.9% in the treatment group and 87.2% in the control group; there was a statistically significant difference between the two groups (P<0.05). The recurrence rate was 5.1% in the treatment group and 13.6% in the control group at the one-year follow-up. There was a statistically significant difference in the recurrence rate between the two groups (P<0.05). Conclusion Acupuncture at point Houxi and other combined points has a better therapeutic effect on cervical spondylotic vertebral arteriopathy. It can markedly reduce the recurrence rate in the patients.

目的探讨认知康复在脑损伤恢复期的重要性和必要性。方法 60例患者随机分为非介入认知康复组(A组)和介入认知康复组(B组),每组30例。A组为只接受部分康复项目(OT、PT、ST或高压氧),B组在A组的基础上加用认知训练。通常康复训练进行3—4次/天,45分钟/次。高压氧治疗每日1次,10—12天为1个疗程,治疗3—5个疗程,平均36个疗程。结果A组与B组比较在LOTCA评价、FIM评价和Fugl-Meyer评价上都有显著性差异,其中LOTCA评价有非常显著性差异。 结论认知康复在脑损伤恢复后期是必要的。

Purpose To explore the clinicopathologic characteristics, pathologic diagnosis and differential diagnosis of extraskeletal myxiod chondrosarcoma. Methods The clinical and pathological features were studied with HE and immunohistochemical staining in 5 cases of extraskeletal myxoid chondrosarcoma, and the related literatures were also reviewed. Results Extraskeletal myxoid chondro-sarcoma was male predominance (4 males: 1 female), and the age ranged from 32 to 62 years with an average of 52 years. Four tumors occurred in thigh and another in chest. Histologically, the neophlasm were composed of round and oval cells. Immunohisto-chemically, the tumor cells were positive for vimentin in five cases, synaptophysin expressed in one case, S-100 showed focal positivity in two cases, but negative for CK, p63, EMA, CD34, SMA in all cases. Molecular genetics detection shows chromosome exchange be-tween number 9 and 22. Conclusion Extraskeletal myxoid chondrosarcoma is a rare tumor which has no special characteristics in clinical and iconography, and its diagnosis mainly depends on the histopathologic features, immunohistochemistry and molecular genet-ics. Extraskeletal myxoid chondrosarcoma grows slowly, but have a high tendency for local recurrence and metastases.

BACKGROUND:Osteosarcoma combined with pathological fracture was often treated by amputation. With clinical application of neoadjuvant chemotherapy and improvement of technology and material of the prosthesis, the limbs of patients with osteosarcoma combined with pathological fracture were reserved. OBJECTIVE:To evaluate the effect of the application of custom-manufactured artificial total knee prosthesis replacement in limb salvage treatment for patients with osteosarcoma combined with pathological fracture. METHODS:A total of 11 patients with pathological fracture with osteosarcoma located in adjacent knee Joint were enrol ed from June 2002 to September 2012. In accordance with individual condition of the patient, limb salvage treatment was designed for knee prosthesis for a tumor. Fol ow-up results were retrospectively analyzed. There were six males (54.5%) and five females (45.5%) and their age ranged from 11 to 50 years old with an average age of 25.4 years old. Onset regions:seven tumors were located in the distal femur and four tumors were in the proximal tibia. Al patients received neoadjuvant chemotherapy, and limb salvage treatment with custom-manufactured artificial knee prosthesis. The fol ow up was performed for 9 to 105 months. RESULTS AND CONCLUSION:In 11 patients after prosthesis replacement, the regional recurrence rates were 18%, lung metastasis rates were 36%. The five-year survival rate was 58%. Four patients developed lung metastases and died in 9 to 24 months postoperatively. During the last fol ow-up, Enneking score of the affected limbs was 11 to 30 points, averagely 23.3 points, with an excellent and good rate of 82%. Results indicated that combined with neoadjuvanet chemotherapy, the application of custom-manufactured artificial total knee prosthesis replacement in the treatment of osteosarcoma located in adjacent knee joint and pathological fracture achieved an ideal outcomes of the limb salvage treatment in the near future. The lone-term effectiveness was expected to be evaluated.

The relation between the critical radius and the particle size distribution for generalized Ostwald type ripening processes whereby the mass transfer coefficient is modelled by a power law was derived. The critical radius is determined by the growth rate, the mass transfer coefficient and the mass balance, and is independent of whether the limiting stationary growth regime has been obtained.
