Objective To describe the up-to-date development in spine and spine cord injuries. Methods To summarize the cl inical and basic research on spine and spine cord injuries were summarized by reviewing papers and combining them with our own experience. Results The occi pitocervical and atlantoaxial fusions by the pedicle or the lateral mass screw were widely used to treat the upper cervical fractures. The anterior cervical plate, posterior pedicle or lateral mass screw fixation techniques were used in treatment of lower cervical fractures. The cl inical appl ication of artificial cervical disc replacement showed the good biomechanical results in treatment of serious cervical disc diseases. However, there were no unified criteria for selection of the surgical approach, fixation level, and fusion model in the treatment of thoracolumbar spine fractures. Lumbar posterior dynamic fixation and artificial disc replacement for treatment of degenerative lumbar disc diseases provided the biomechanical stabil ization and reduced the morbidity of adjacent segment diseases, but there was lack of long-term follow-up results. The basic research in spine cord injuries, especially in apoptotic signal pathway, made great progress. The biological treatment including cell transplantation and gene therapy provided the sol id theoretical foundation for cl inical appl ication. Conclusion The reparative and reconstructive development in spine and spine cord injuries has made great progress in recent years.
Abstract From 1980 to 1985, 21 cases of free transplantation of fibula were performed. There were 6 children in this series, and 4 children were followed up for 9 to 12 years (average 10 years). The Xray showed that distal epiphysis of tibia had a normal width at the medial side and gradully tapered toward the lateral side in a "wedgeshaped" apperance. The articular space of the tibiotalar joint inclined to the fibularside. The hight of the talus was higher laterally, leading to eversion deformity of the ankle joint. The medial and lateral malleoli were smaller than normal, and thus the ankle joint mortise became shallow. The trabeculae of the tibia were irregularly arranged. The lateral cortex of the tibia was thicker than that of the medial one. In one case, the bone density of the lateral side of the "wedgeshaped" epiphysis had increased as high as that ofthe cortex with disappearance of trabeculae. The biomechanics of fibular boneand the mechanism of development of disturbance of ankle joint in childhood were analyzed. Close attention should be paid to this disturbance.
Objective To study the clinical effects of laparoscope combined with choledochoscope in patients with cholecystolithiasis and choledocholithiasis. Methods Clinical data of 74 patients with cholecystolithiasis and choledocholithiasis between Mar. 2009 and Feb. 2011 in our hospital were retrospectively analyzed. Among them， 37 cases underwent the laparoscope combined with choledochoscope operation （referred to as the double mirror operation group） and 37 cases underwent the conventional open operation （open operation group）. The intraoperative conditions， therapeutic effect， and complications of patients in 2 groups were compared. Results The stone clearance rates of the two groups were 100%. The recurrence rate of 2 groups in the follow-up process was no significantly difference （P＞0.05）. In the double mirror operation group， the operative time was significantly longer than that open operation group （P＜0.01）；the intraoperative bleeding was significantly less than that open operation group （P＜0.01）；the anal exhaust time after operation， get out of bed time after operation， and total duration of hospitalization were significantly shorter than that open operation group （P＜0.01）；and the incidence of postoperative complications was significantly lower than that open oper-ation group（P＜0.01）. Conclusion Laparoscope combined with choledochoscope in treatment of cholecystolithiasis and choledocholithiasis patients has exact effects， with minor trauma， quicker recovery， and fewer complications， and it’s worthy of promotion.
【Abstract】 Objective To study the expressions of cyclooxygenase-2 (Cox-2) and angiopoietin-2 (Ang-2) in colorectal cancer tissues, cancer adjacent tissues and normal colorectal tissues, and the relationship between these expressions and the clinicopathologic features of colorectal cancer. Methods Forty-five excised samples of colorectal adenocarcinoma were confirmed pathologically and 39 of them were of well or moderately differentiated and 6 of poorly differentiated. Lymph nodes metastasis developed in 30 patients. And 15 cases were in stage of A or B and the rest were in the stage of C or D according to the Dukes stage. Taken PBS as the negative control and the verified Cox-2 or Ang-2 positive sections as positive controls, this study detected the expressions of Cox-2 and Ang-2 protein in 45 colorectal cancer tissues, 45 cancer adjacent tissues and 15 normal colorectal tissues by using immunohistochemical SP technique method. Results Cox-2 and Ang-2 were expressed in colorectal cancer tissues and cancer adjacent tissues, but were not expressed in normal colorectal tissues. In 45 colorectal cancer tissues, the positive expression rates of Cox-2 and Ang-2 were 80.0% and 66.7%; in 45 cancer adjacent tissues, the positive expression rates of Cox-2 and Ang-2 were 35.6% and 11.1%, respectively. The positive expression rates of both Cox-2 and Ang-2 in colorectal cancer tissues were significantly higher than those in cancer adjacent and normal colorectal tissues. There were close correlations between the expressions of Cox-2 and Ang-2 and some pathologic features, such as lymph node metastasis and Dukes stage; whereas there were no significant association between the expressions and gender, histological type and position of tumor. There was also a close correlation between the expressions of Cox-2 and Ang-2 themselves. Conclusion Cox-2 and Ang-2 play an important role in the occurrence and development of colorectal cancer. The use of specific inhibitor of Cox-2 as a treatment for colorectal cancer may become feasible and necessary.

Serum alkaline phosphatase (ALP) has long been used as a biomarker for the liver, kidney, and bone. Currently, increasing evidence suggests a correlation between serum ALP and cardiovascular disease (CVD). Research has shown that serum ALP affects endothelial cell function and induces changes in pyrophosphate through various mechanisms to accelerate vascular calcification and promote cardiac fibrosis. Therefore, this article reviews the potential value of serum ALP in CVD through relevant research, revealing the specific relationship between serum ALP and CVD, in order to provide new ideas for the prevention and treatment of CVD.
