As a distinct T cell subset with acknowledged specific function and marker, CD4+CD25+FOXP3+ regulatory T cells are thought to dampen T-cell immunity and to be the main obstacle tempering antitumor immunotherapy. Accumulating evidence has confirmed an increased pool of regulatory T cells both in the peripheral blood and the tumor microenvironment of cancer patients, which are indicative of disease progression, response to therapy, invasive phenotype and prognosis. Therefore, manipulation of regulatory T cells—including depletion, blocking trafficking into tumors, or reducing their differentiation and suppressive mechanisms—and concomitant stimulation of effector T cells, systemically or locally in tumors, represent new strategies for cancer treatment.

Objective To evaluate the clinical results and safety of pedicle screw fixation for the treatment of spinal disorders. Methods From January 1988 to December 1999, 475 patients (216 males amd 259 females) with an average age of 49.1 years old in the male and an average age of 48.7 years old in the female, underwent pedicle screw fixation for spinal disorders. Diagnoses included 217 cases of spondylolisthesis, 76 lumbar stenosis, 32 degenerative lumbar spine instability, 72 thoracic or lumbar spine fractures, 60 scoliosis, and 18 others. The instrumentations were as follows: Dick 55 cases, Steffee 79 cases, CD 54 cases, RF 82 cases, DRFS 59 cases, TSRH 29 cases, USS 19 cases, SOCON 44 cases, Dynalock 24 cases, Diapson 22 cases, Tenor 5 cases, and CDH 3 cases. The fusion ranges involved one segment in 310 cases, two segments in 96 cases, and three segments in 9 cases. Hooks were applied in 60 cases. Results Four hundreds and twenty eight patients(90.l%) were followed up for (6.0?3.7)years. In the patients of degenerative spondylolisthesis, spondylolysis, lumbar stenosis, degenerative lumbar instability and thoracolumbar fracture, the amelioration of nerve function was 79.9%, 87.9%, 77.0%, 89.3%and 62.7%; the improvement of spinal motion was 90.5%, 90.9%, 83.6%, 92.9%and 52.5%; the amelioration of low back pain was 89.9%, 87.9%, 85.2%, 89.3%and 84.8%; and the amelioration of leg pain was 93.9%, 90.9%, 93.4%, 92.9%and 79.7%respectively. The mean reduction rate of degenerative spondylolisthesis, spondylolysis and spinal fracture was 90.5%, 87.9%and 91.5%respectively. The SOCON technique showed the highest reduction rate of an average of 92.3%, followed by RF of 90.8%, and Dick, Steffee and DRFS of 81.2%, while other instrumentations showed no satisfactory result in reduction. Complications occurred in 90 cases, in which 26 cases occurred during operation with the incidence of 6.1%, while 64 occurred after operation with the incidence of 15.0%. Conclusion Pedicle screws provide fixation of short segments with satisfactory clinical results and relatively high fusion rate. Perfect surgical technique is the key to reduce the incidence of complications.

Simulated teaching method is a necessary complement to theoretical teaching of health law,which meets the practical-oriented reform need and cultivates students with the literacy as a legal professional.The teaching method demands more requirements on teachers,students,teaching materials,organizational management,and more attention on contextual design,preparation details,implementation activities and evaluation of teaching.

The construction of the model curricula is the important branch of teaching quality engineering. The key to the development of the model curricula lies in the reform of the teaching model. As required to the national standards of the model curricula and to the purpose of innovative educational philosophy,with the years of continuous exploration and practice,the clinical immunology examination curriculum has kept developing from the teaching staff,teaching condition,content of course,teaching method and means etc.,which has brought about satisfactory teaching effects. Thus it is forming the model curricula with special features.

OBJECTIVE:To investigate clinical efficacy and safety of conjugeted estrogen tablets combined with Salmon calci-tonin acetate injection and Alendronate sodium tablets in the treatment of osteoporosis in postmenopausal. METHODS:148 post-menopausal women with osteoporosis were randomly divided into observation group(78 cases)and control group(70 cases). Con-trol group was given Salmon calcitonin acetate injection hypodermically or intramuscularly,100 IU each time,once a day in first week,every two days in second week,every three days in third week,21 times of consecutive injection as a treatment course;Alendronate sodium tablet,70 mg each time,once a week,3 months as a treatment course. Based on control group,observation group was additionally given conjugeted estrogen tablets,0.625 mg each time,qd,for consecutive 3 weeks,drug withdrawal for one week,and then continued to taking drug,for 3 months in total. Clinical efficacy of 2 groups were observed as well as BGP, bone metabolism index as human collagen type Ⅰ N-terminal peptide (NTX) and ALP,bone density and ADR before and after treatment. RESULTS:After treatment,total effective rate of observation group was 94.87%,which was significantly higher than 78.57% in control group,with statistical significance(P<0.05);BGP,lumbar spine and thigh-bone density of 2 groups were all improved significantly,and the improvement of observation group was more significant than that of control group,with statistical significance (P<0.05). NTX and ALP of 2 groups were decreased significantly,and the decrease of observation group was more significant than that of control group,with statistical significance (P<0.05). The incidence of ADR was 12.82% in observation group and 8.57% in control group,without statistical significance (P>0.05);various ADR disappeared after drug withdrawal. CONCLUSIONS:Conjugeted estrogen tablets combined with Salmon calcitonin acetate injection and Alendronate sodium tablets can effectively relieve bone pain,regulate bone metabolism,increase bone density and induce slight ADR in postmenopausal with osteoporosis.
