FOX genes code transcription factors. FOXO3a,FOXM1,FOXP3 are members of FOX genes family,which are associated with leukemia. Phosphorylated FOXO3a which loses the function of suppressing leu-kemia is inactive. Phosphorylated FOXO3a expresses in leukemic cell cytoplasm. FOXM1 is an oncogenesis tran-scription factor. FOXM1 highly expresses in myeloid leukemic cells. Expression of FOXP3 in leukemic cells has diversity. FOXP3 mainly expresses in T cell leukemic cells. These genes abrrant expressions play a key role in leukemia pathogenesis,development,therapy,drug resistance and prognosis.

Zebrafish was selected as model animal, and glucocorticoid dexamethasone was used as a model compound to establish a rapid and high efficient osteopenia model. Zebrafish larvae at 4 days post fertilization (dpf) were exposed to a serial concentrations of dexamethasone solutions, and 0.5% DMSO was selected as the vehicle control group. All groups were incubated in 24-well plates (28.5 degrees C) until 9 dpf. In addition, effects of 10 micromol x L(-1) dexamethasone on preventing against osteopenia induced by etidronate disodium were also investigated. Zebrafish bones at 9 dpf were stained with alizarin red. Quantitative analysis of the stained area was performed by microscopic inspection and digital imaging methods to reflect the amount of bone mineralization. Results showed that dexamethasone group at 2.5, 10 and 25 micromol x L(-1) can decrease the staining area and the staining optical density values of zebrafish head bones when compared with the vehicle control group (0.5% DMSO), which suggested that dexamethasone can significantly reduce the zebrafish mineralized bone and the bone mineral density. Results also showed that 15 and 30 microg x mL(-1) etidronate disodium can increase the mineralized matrix of zebrafish head bone and prevent against osteopenia induced by dexamethasone. In conclusion, the study indicated that zebrafish can be an idea osteopenia model induced by dexamethasone.

OBJECTIVE:To study the cardiac and skeletal toxicity of retinoic acid (RA) in Danio rerio at early life stage. METHODS:Danio rerio embryos of 24 hours post fertilization(hpf)were used as toxicity model and were exposed under medium with various concentrations of RA(0.1,1,10,25,100 μmol/L). The morphology of embryos and larvae hearts were observed 24,48 h after exposed. LC50 was calculated. Danio rerio larvae of 4 days post fertilization (dpf) were used as skeletal deformity model and were exposed with a series of RA at various concentration(0.1,1,10,25,50μmol/L). They were sacrificed 5 d later, and then Danio rerio skeleton were fixed for staining with alizarin red. The microscopic was used to observe the difference of stained skeleton area. RESULTS:RA caused significant adverse effects on hatching capabilities of Danio rerio embryos,and the ob-vious malformation features were produced during the culture process. 1-100 μmol/L RA could cause heart malformation in Danio rerio embryos and larvae,and the main heart malformation characteristics included heart linearization,pericardial edema,yolksa-cedema,hemocytes accumulation incardiac region. 100 μmol/L RA could inhibit the hatching capabilities of Danio rerio embryos, and caused lethal effects on embryos and larvae. The LC50 were 36.44,23.69 μmol/L after exposed for 24,48 h. 0.1-50 μmol/L RA induced vertebral column sclerotization of Danio rerio embryos and larvae in advance,which was positively associated with the con-centration of RA. CONCLUSIONS:RA can cause cardiac and skeletal toxicity in Danio rerio embryo and larvae,which is positive-ly associated with the concentration of RA.

Objective:To determine the effect of apatinib combined with Xiaoyan decoction for the treatment of non-squamous non-small cell lung cancer. Methods:Thirty-eight patients with non-squamous non-small cell lung cancer were randomly categorized into apatinib group (group A, 18 cases) and apatinib combined with Xiaoyan decoction group (group B, 20 cases). All patients did not under-go surgical treatment, radiotherapy, or chemotherapy during the study. Results:The median progression free survival (mPFS) of ad-vanced non-squamous non-small cell lung cancer patients reached up to 3 months. The mPFS, objective response rate, and disease control rate of the apatinib combined with Xiaoyan decoction group showed no significant difference and statistical significance (P>0.05). The apatinib combined with Xiaoyan decoction group was superior to the apatinib group with regard to alleviating clinical symp-toms and adverse reactions (P<0.05). Conclusion:Xiaoyan decoction combined with apatinib can improve the clinical symptoms of pa-tients and reduce the incidence of adverse reactions in the treatment of advanced non-squamous non-small cell lung cancer.

BACKGROUND: The treatment of upper cervical spine disorders through a posterior pedicle fixation approach have been carried out in some domestic large hospitals, but this surgery is still considered as a difficulty of cervical spine surgery. In order to minimize the risk of surgery, the authors designed a program of individual operations, and combined with self-developed pedicle locating and directing speculum to determine precise intraoperative position of pedicle screws, and no report is found by searching related database in China.OBJECTIVE: To improve the one-time success rate of internal fixation screws, to investigate the biomechanical effect of the implant, to formulate a simple, practical, individual protocol for atiantoaxial pedicle screw-plate system based on related data. METHODS: A total of 31 patients were recruited from Department of Orthopaedics in the 251 Hospital of Chinese PLA, between January 2002 and September 2006. Under the guidance of self-made atlantoaxial locating and directing speculum, the entrance point and angle for screw insertion, as well as screw diameter and length were determined according to the results of X-ray and CT measurement. Atlas pedicle screw was inserted at left (19.93±1.32) mm, and right (19.16±1.3) mm; Atlas pedicle screw insertion angle to inside was left (23.72±2.09)°, and right (23.35±1.91)°; Atlas pedicle screw insertion angle to side of head was (9.00±1.20)°. Axis pedicle screw was inserted at left (13.14±0.82) mm, and right (13.85±0.79) mm; Axis pedicle screw insertion angle to inside was left (24.52±1.26)°, and right (20.42±1.42)°; Axis pedicle screw insertion angle to side of head was (25.00±3.00)°.RESULTS AND CONCLUSION: ①Totally 124 pedicle screws were implanted into 31 patients, and 122 screws were of one-time success. The precision rate was 98.39%. Two screws were secondly inserted because of cutting lateral cortical bone of pedicle for deviation of inward angle. ②Occipital neuralgia was found in 2 cases postoperatively and cured after one month of treatment;screws penetrated atlas left vertebral lateral wall in 2 cases, no spinal or vertebral artery injury was found. ③Radiographs showed that atlas was completely reduced in all patients, and apposition of dentoid process of axis fracture was good. CT films showed the screws a good location to the vertebrarterial spinal cord. ④The follow-up visit was averaged of 10.5 months. Bony fusion was found in all patients. No screw-plate breakage was found. No inflammatory or rejection reactions occurred.⑤By JOA scale, there were 16 cases of excellent, 12 cases of good, 2 cases of fine, and 1 case of poor. The excellent and good rate was 90%. It is suggested that the success rate of atlantoaxial pedicle screw-plate mplantation can be improved through a biomechanical angle.
