Objective To study retrospectively the efficacy and complications of different surgery approaches used to treat primary spinal tumors and to discuss the surgical strategy in treating them. Methods 135 patients with primary spinal tumors had been treated between July 1998 and July 2005. The following diagnoses were made based on histopathological findings: multiple myeloma in 25 patients, giant cell tumor in 17, neurofibroma or neurilemmoma in 23, chondrosarcoma in 7, osteoblastoma in 6, aneurysmal bone cyst in 4, lymphoma in 9, eosinophilic granuloma in 6, hemangioma in 15, osteosarcoma in 3, Ewing sarcoma in 5, and other different tumors in 15. Anterior approach and posterior approach was used in 73 cases and 31 cases respectively. Posterolateral approach was used in 13 cases and combination of anterior and posterior approach was used in 18 cases. Results Pain relief was obtained in 126 of the 135 patients(93.3%). Improved neurological function was seen in 86 of 92 patients who had suffered from impaired neurological function. No severe complications were found in the follow-up period. Cerebrospinal fluid leakage was observed in 11 patients, and which was successfully treated using antibiotics therapy and raising the foot of the bed. 3 patients suffered from stress ulcer after operation, but they recovered soon after blood transfusion and anti-acid treatment. Other complications included subcutaneous emphysema (in 3 patients), superficial wound infection (in 3 patients),nerve root injury (in 2 patients), implant loosening (in 2 patients), and neurological morbidity due to surgery (in 1 patient). Conclusion When single or two adjacent vertebrae are involved by spinal tumors such as giant cell tumor and chondrosarcoma, tumor resection should be performed through combination of anterior and posterior approach. Aggressive resection based on the Tomita or WBB staging system is the treatment most likely to achieve long-term local control.

Objective: The purpose of this study was to establish a human lung adenocarcinoma cell line SPC-A-1 BM with high bone metastatic potential and detect the bone metastasis in immunodeficient NIH-BNX mice by using in vivo radionuclide bone imaging technology. Methods: The human lung adenocarcinoma cell line SPC-A-1 was injected into left ventricle of mice to induce bone metastasis. The metastatic lesions in mice were traced by radionuclide bone imaging agent. The lesion was resected and the isolated tumor cells were cultured in vitro to obtain the bone metastatic human lung adenocarcinoma cells. The first passage of bone metastatic human lung adenocarcinoma cells were injected again into mice via vascular system (artery and vein) or transplanted in lung orthotopically. The cells were repeatedly screened for several times. Results: Chromosome analysis showed that the bone metastatic SPC-A-1BM cells detected by radionuclide bone imaging still kept the properties of human origin after several cycles of screening in vivo and in vitro. The influence of 99m Tc-MDP (111 MBq) on the growth of SPC-A-1BM cells was similar with or a little less than X ray film (40 kV, 2 mA, 4 s). The overall sensitivity, specificity and accuracy of radionuclide bone imaging and X-ray film were 97.6%, 73.3%, 94% and 31.3%, 100%, 43%, respectively. Conclusion: The radionuclide bone imaging offers a practical and convenient method for establishing a human lung adenocarcinoma cell line SPC-A-1BM with high bone metastatic potential and detecting the bone metastasis in immunodeficient BNX mice.

AIM: To observe the efficacy of intravitreal injection with ranibizumab combined with laser photocoagulation for macular edema ( ME ) secondary to macular branch retinal vein occlusion( MBRVO) .
METHODS:A retrospective analysis included 33 patients (33 eyes) with ME secondary to MBRVO were taken. All patients received intravitreal injection of 0. 5mg ranibizumab ( 0. 05ml ) at first visit. The continue PRN treatment and laser photocoagulation were based on the visual acuity changes and optical coherence tomography findings. The changes of best corrected visual acuity ( BCVA) , central macular thickness( CMT) , and amplitude density and latency of P1 wave in mfERG were observed before treatment and 6mo after treatment.
RESULTS: Before the treatment, logMAR was 0. 68±0.35, 6mo after treatment was 0. 34±0. 23, BCVA was improved obviously ( P < 0. 01 ), BCVA in 21 patients ( 63.64%) were improved in two rows among all the patients. CMT before treatment was(487. 30±63. 58) μm, after treatment was(238. 84±52. 66) μm(P<0. 01). The amplitude densities of P1 wave in ring 1, ring 2 and ring 3 after treatment were significantly increased(all P<0. 01), and the latencies were decrease ( all P < 0. 05 ). The conjunctival hemorrhage was observed in 2 eyes after treatment.
CONCLUSION: Intravitreal injection with ranibizumab combined with laser photocoagulation for ME secondary to MBRVO can reduce the CMT and improve visual function.

Objective:To analyze the related risk factors for esophageal variceal bleeding(EVB)in patients with hepatocirrhosis and portal hypertension,so as to provide clinical evidences for establishing preventive measures for EVB. Methods:Using"*esophag*","varice*","bleeding","hemorrhage",and"risk factor*"as the key words,we searched the clinical studies(1986-2006)about the risk factors of EVB in hepatocirrhosis patients in PubMed,Medline,Chinese Biomedical Database,Elsevier Database,OVID Database,etc.for Meta-analysis.The odds ratio(OR)of each risk factor was estimated and the 95% confidence interval[95% CI]was calculated.Results:Totally 19 papers met our criteria and were included in this Meta-analysis.The 19 papers involved 995 EVB patients and 1854 controls.Meta-analysis revealed that a hepatic function of Child C,decreased prothrombin activity,hypoalbuminemia,severe esophageal varices,positive red-color sign,extended portal vein width and splenic vein width,thrombopenia,leucopenia and anemia were the risk factors of EVB;a hepatic function of Child A and mild esophageal varices were the protective factors of EVB.The gender,age,hepatic function of Child B,ascites, hepatic encephalopathy,hyperbilirubinemia and midrange esophageal varices were not significantly associated with EVB. Conclusion:Improvement of poor hepatic function,blood coagulation status,hypoalbuminemia and treatment & prevention of severe esophageal varices(by endoscopic variceal ligation,devascularization and shunt)can help to reduce the incidence of EVB.

Objective To investigate the expression of glioma-associated oncogene 2 (Gli2) in giant cell tumor of bone, and analyze the differential expression in the different classification of imaging and pathology and the recurrent diseases, to discuss its role and significance in the pathogenesis and prognosis of giant cell tumor of bone. Methods 46 cases of giant cell tumor of bone who received the primary treatment in Peking University Peopleˊs Hospital during Jan 2009 and Dec 2012 and had the full data of treatment and could be follow-up were collected. Among which there were 40 benign cases and 6 malignant cases. The expression of Gli2 in the different cases of giant cell tumor of bone were detected by immunohistochemistry and real-time PCR, and its effect on the prognosis of giant cell tumor of bone was analyzed. Results Immunohistochemistry revealed positive expression of Gli2 in giant cell tumor of bone. The positive rate of Gli2 in malignant cases was significantly higher than that in benign cases [100.0 % (6/6) vs 55.0 % (22/40), P=0.035], and only found increasing trend but no significant difference among recurrent cases (P=0.204). Results of real-time PCR indicated that Gli2 highly expressed in giant cell tumor of bone, and the increasing trend of expression in different pathological types, different image classifications and recurrent cases, but no statistical different were found (all P>0.05). The expression correlation analysis showed that the expression of Gli2 and PTHrP, and the expression of RANKL and OPG either had a significant correlation (both P< 0.05). Additionally the expression of PTHrP and RANKL had a moderate correlation (P<0.05). Conclusions The expression level of Gli2 is high in giant cell tumor of bone, and Gli2 may be involved in recurrence,metastasis and malignant transformation. Gli2 may effect the osteolytic process of giant cell tumor of bone by the regulation mechanism of Gli2-PTHrP-RANKL pathway.

Two regression models, based on panel data over the period of 2000-2011, are built and used to analyze what factors determine China's exports of primary and semi-finished products of traditional Chinese medicine to ASEAN. The results indicate that, China GDP, the ratio of ASEAN to China GDP per capita, average export price, the ratio of state-owned assets to total assets, have a significant positive influence on the export volumes of primary products of Chinese medicine. At the same time, RMB appreciation, the ratio of three kinds of foreign-invested assets to total assets, China-ASEAN Early Harvest Program, ASEAN-China Free Trade Area have a significant negative influence. In respect of the export volumes of semi-finished products of Chinese medicine, the significant influential factors are ASEAN GDP and the ratio of ASEAN to China GDP per capita. The former is positive and the latter is negative. In order to optimize the commodity composition of experts, it is needed to increase export volumes of both primary and semi-finished products of Chinese medicine. According to the analysis above, some proposals are put forward, such as, improving the performance of foreign capital, playing an exemplary and leading role in technological innovation by state-owned enterprises, taking advantage of bargaining power of suppliers, increasing outward foreign direct investment.
