A computer-based online search was conducted in PUMMED, English Medical Current Contents (EMCC), China Journal Full-text Database (CJFD), and Wanfang Database to summarize application and research progress of large-diameter femoral head hip prosthesis from January 1995 to January 2008. There were 62 literatures in total. Previous studies reported that when diameter of femoral head hip prosthesis was>32mm, joint worn out remarkably. During recent years, more and more basic and clinical researches demonstrate that diameter of femoral head is not correlated with wear rate; in particular, diameter of femoral head is not related to wear rate of artificial joint made by high cross linked polyethylene, metal, and ceramics. The superiority of large-diameter femoral head hip prosthesis has been paid more attention because of stability and activity. With the enlargement of diameter of femoral head, dislocated incidence decreases remarkably, and improvement of head-neck ratio increases the activity of prosthesis and reduces collision between two prostheses. Recently, large-diameter femoral head hip prosthesis has been widely applied for metal-on-mental hip joint, in particular, for hip resurfacing arthroplasty; in addition, large-diameter femoral head hip prosthesis plays a distinct role in joint replacement.

Objective To study the effect of different therapies for posterior lumbar disc herniation.Methods A total of 8 000 patients with lumbar disc posterior surgery were enrolled in this research at our hospital.The technical points of the patients in different times were analysed.The results of the operation were observed.Results From January 1980 to December 1990,patients underwent laminectomy.From January 1991 to December 2000,patients were treated with laminectomy and semi-lamina.From January 2001 to December 2016,the open window accounted for 86.0％,expanding the window or semi-lamina accounted for 11.0％,and the whole laminar plate only accounted for 3.0％.After 2000,the accuracy of the diagnosis was 98.0％,the excellent rate of operation was 99.8％,the average operation time was(80±15)min,and the blood loss was(100±20)mL.Among them,the rate of I/A healing was 99.8％,dural tear rate was 4.0％,nerve root injury rate was 0.5％,and cerebrospinal fluid leakage rate was 0.9％.The incidence of complications in the cases after 2000 was significantly lower.Conclusion By summarizing the operation technique of posterior lumbar disc herniation,the operation error can be avoided and the incidence of complications of surgical injury can be reduced.

Flipped classrooms have been developed in recent years at home and abroad although there is no systematic application in Chinese higher education institutions. College of Stomatology Shanghai Jiao Tong University has discussed the application prospect of flipped classrooms in medical education and methods of increasing effect and quality by informational means and classroom reform through a case de-sign and application in stomatology, in which performance comparison of the students in flipped classroom and traditional classroom is done as well as recognition of the students to flipped classrooms by a question-naire survey. Still, procedure, experience, supporting conditions and tips on the design and application have been concluded. The practice in classrooms tells us the students accept flipped classrooms positively and scientific design and application may increase teaching result as an effect method. Education management department of higher education institutions and faculty may take advantage of that method with varying degrees.

The activities of low density lipoprotein (LDL) receptors in 15 organs and tissues from 5 human fetuses of the ages of 22 to 34 weeks were determined using a membrane filter assay of the specific binding of ~(125)I-LDL to tissue homogenates. The results showed that the adrenal cortex (465 ng/mg protein) had the highest activity of ~(125)I LDL specific binding seven times than that of the medulla. Adipose tissue (214 ng/mg protein) and liver (102 ng/mg protein) ranked second. Relatively high bindings were also observed in the skeletal muscle (89 ng/mg protein), brain (65 ng/mg protein), kidney (60 ng/mg protein) and spinal cord (56ng/mg protein). It was found that the activity of LDL receptors in the central nervous system of human fetus was higher than that of cows, of human adultsand of humam fetuses of 16 to 20 weeks as reported by other investigators. Relatively high level of LDL receptor mRNA in human fetal brain was also found by ~(32)P-cDNA probe hybridization analysis. It is suggested that the growing and developing central nervous system of human fetus reqiresmore cholesterol. In addition, We also observed preliminarily that the tendency of LDL receptors activities in liver and adrenal gland cortex were gradually inereased with fetal age.

0.05).Conclusion DTI can noninvasive detect the potential disorder of corpus eallosum in vivo,thus providing useful information to differentiate the cerebral ischemia disease from multiple sclerosis.

Objective To study the inhibition effect of anti-CD 25 monoclonal antibody (Simulect) to the activated T cells in the recipients of kidney transplantation. Methods Forty-six recipients of renal transplantation were randomly divided into therapeutic group with simulect (23 cases) and control group (23 cases).All recipients in both groups received immunosuppressive therapy with neoral,azatheoprine and predonine conventionally.The recipients in simulect group received additionally 20 mg simulect at 2h preoprative and 4d postoperative,respectively.Several phenotypes of lymphocyte in the peripheral blood of all recipients were observed sequentially with flow cystometer. Results Compared with the control group,the number of activated T cells(CD + 25 ) decreased significantly within 24h after the first dose in the patients who received simulect,and the level of the cells that expressed CD 25 was significantly lower than that of control during the whole observation( P

Objective To evaluate the clinical efficacy and the surgical treatment of spinal tuber-culosis by debridement, fusion and internal fixation to restore stability of the spine. Methods One hundred and fifty-two patients with spinal tuberculosis were treated surgically between 1996 and 2002. There were 15 in cervical spine, 67 in thoracic spine, 17 in thoracolumbar spine and 53 in lumbar spine. The lesion was of 1-3 levels without jumping lesions. The surgical procedures included: 1) anterior debridement, fusion with autograft and internal fixation with plate. 2) lateral debridement with posterior fusion and pedicle screw fix-ation. 3) posterior debridement, fusion and pedicle screw fixation. 4) anterior debridement and posterior fu-sion and fixation. All patients wore a brace for 3-5 months and chemotherapy was given for 6-9 months postoperatively. The blood test and imaging evaluation were undergone. All patients were followed for 3 to 5 years postoperatively. Results 1) The average operation time and blood loss was 4.5 hours and 650 ml for combined anterior and posterior procedure, 3.5 hours and 450 ml for anterior procedure and 3 hours and 350 ml for the other two procedures. 2) In regard to complications: major blood vessel injury in one case, temporary sinus formation in 5 and loosening and breaking of the instrumentation in 3. 3) All patients had relief of the symptoms and ambulation 1-2 weeks postoperatively. Normal daily function was recovered at 6-8 weeks and solid fusion was observed in 4-6 months postoperatively. All patients were cured of tubercu-losis lesions in spinal column or on other region, and there was no recurrence. Conclusion Effective chemotherapy and radical debridement of the lesion are the basis of success of surgical treatment of spinal tuberculosis. Fusion and internal fixation were the keys for restoration of the stability of spinal column, solid fusion and correction of the kyphotic deformity.

As the rapid growth of population and economic development,the types and intensity of water pollution in urban river stream are increasing,which on one hand restrict the sustainable development of the social,economic and environment,on the other hand,damage people health. Since having safety,economy,practicality,systematic and other merits,ecological remedy technology has been the main means for controlling river contamination. In this paper,the recent researches on the ecological restoration technique for the urban stream in China in recent years were reviewed.
