ABSTRACT
Objective To explore the effect of paraspinal approach and posterior median approach for one -stage decompression recon-struction in the treatment of thoracolumbar spine fracture and dislocation .Methods From January 2012 to January 2014, 60 patients with thoracolumbar spine fracture and dislocation who were admitted and treated in our hospital were selected as the research objects .All patients received one-stage decompression reconstruction for treatment .According to the methods of approach , the patients were divided into the ob-servation group and the control group .The 30 cases in observation group were treated by paraspinal approach while the other 30 cases in con-trol group were treated by posterior median approach .Visual analogue score ( VAS) was applied .The status of surgery , recovery of centrum height, changes of Cobb angle as well as the occurrence rate of postoperative complications in the two groups were recorded .Results In the observation group, the operative time, time in bed and length of stay were (89.16 ±11.63) min, (39.75 ±8.69) h and (3.96 ±1.04) d respectively, which were shorter than those in the control group .The intraoperative blood loss was (89.64 ±13.62) mL which was lower than that in the control group and the difference was significant (P<0.05).One week after operation, the anterior and posterior height of centrum in the observation group increased significantly while Cobb angle significantly reduced .Compared with those before the treatment , the difference was significant (P<0.05).The maximum coronary diameter and maximum sagittal diameter of paraspinal muscles in the ob -servation group after the treatment were (48.96 ±5.34)mm and (18.16 ±6.74)mm respectively, which were significantly higher than those in the control group and the difference was significant (P<0.05).The incidence of lumbar and back pain in the observation group was 3.33%which was lower than 23.33%in the control group and the difference was statistically significant (P<0.05).Conclusion To carry out decompression reconstruction through paraspinal approach can reduce the the pain degree of patients and the incidence of lumbar and back pain after operation .
ABSTRACT
Objective To study the clinical effect of transpedicular vertebral osteotomy spine shortening in treating spinal kyphosis com-plicated with spinal cord nerve dysfunction. Methods A total of 80 patients with spinal kyphosis complicated with spinal cord nerve dys-function in our hospital from May 2013 to June 2014 were enrolled and randomly divided into observation group(n=40) and control group (n=40). The observation group received transpedicular vertebral osteotomy,and the control group received lamina and facet osteotomy. The situation of surgery,vertebral healing and spinal cord function condition,treatment effect between two groups were compared. Results The operation time and postoperative ambulation time of observation group were shorter than those of control group [(76. 52 ± 9. 1) vs (113. 46 ± 13. 44) min,(3. 28 ± 0. 43) vs (5. 67 ± 0. 68) d]. The postoperative bleeding volume,postoperative drainage volume of observation group were less than those of control group [(36. 14 ± 4. 28) vs (55. 23 ± 7. 15) mL,(17. 92 ± 2. 12) vs (29. 64 ± 4. 28) mL]. The Cobb angle and residual urine volume,initial and strong urinary bladder capacity,maximum urinary output of observation group were significantly less than those of control group [(6. 12 ± 0. 68) vs(9. 78 ± 1. 21) mL,(241. 45 ± 28. 56) vs(335. 54 ± 36. 86) mL,(456. 56 ± 51. 78) vs (586. 35 ± 63. 12) mL,(63. 78 ± 7. 24) vs (96. 32 ± 10. 22) mL]. The intervertebral height of observation group was higher than that of control group [(12. 62 ± 2. 81) vs (8. 41 ± 1. 32) mm]. The excellent rate of observation group was significantly higher than that of control group(97. 50%vs 82. 50%). Conclusion Transpedicular vertebral osteotomy spine shortening is helpful to reduce operation wound, pro-mote postoperative recovery,correct kyphotic deformity and improve neurological functionin,improve therapeutic effect.
ABSTRACT
<p><b>OBJECTIVE</b>To detect common environmental pollutants in human body.</p><p><b>METHODS</b>Urine samples were collected from 80 healthy subjects. Chromatography mass spectrometry (GC-MS), HPLC and ELISA were applied to detect several common environmental pollutants in urine samples.</p><p><b>RESULTS</b>DBP and methylbenzene were present in 75.3% and 41.2% of urine samples. The methanal and AFM1 were found in most of urine samples (approximately 91≊97%). By contrast, PCBs, CPZ, 4, 5-DCC were found in less than 5 samples, but there was no TMT detected.</p><p><b>CONCLUSION</b>Some of the environmental pollutants including carcinogens are detected in urine samples in this study.</p>

<p><b>OBJECTIVE</b>To prepare the antibodies against salbutamol (SAL) with high sensitivity and to develop an indirect competitive enzyme-linked immunoassay (ic-ELISA) for fast detection of SAL.</p><p><b>METHODS</b>The New Zealand white rabbits were immunized with SAL in a small dose and long period mode. The method of ic-ELISA was optimized and adopted for the detection of a series of SAL samples, then the standard curve of SAL was established. The precision and the recoveries of the method were determined.</p><p><b>RESULTS</b>The antibodies with high sensitivity towards SAL were prepared with a IC50 of 12.21 ng/ml. The ic-ELISA method for SAL measurement was established, the recoveries of measurement was between 95%-105% and the CV was <3%.</p><p><b>CONCLUSION</b>The antibodies against salbutamol have been prepared and an indirect competitive enzyme-linked immunoassay for fast and specific detection of SAL has been developed.</p>

<p><b>OBJECTIVE</b>To synthesize artificial diethylstilbestrol (DES) antigen and to prepare DES polyclonal antibody with high titer and sensitivity.</p><p><b>METHODS</b>The derivative of DES (DES-HS) was synthesized from diethylstilbestrol, ethyl bromoacetate,bovine serum albumin (BSA) and chicken ovalbumin (OVA) with the nucleophilic substitution reaction; the compound was identified by electrospray ionization mass spectrometry(ESI-MS). The DES-HS and the carrier proteins (BSA, OVA) were cross-linked to prepare the artificial antigen; the UV absorption spectrophotometry and high performance liquid chromatography (HPLC) were used to identify the prepared artificial antigen.

ABSTRACT
It is the prerequisite and foundation to set up the institutional ethics committee of organ transplantation that holds a proper structure for ethics committee to play a key role effectively.In terms of our reality and based on the successful practices and guidelines of international organizations of ethics committee,some suggestions and guidelines on reasonably standardizing the structure of ethics committee for organ transplantation in China are given to guarantee ethics committee to fulfill its target functions.
ABSTRACT
Medical humanitarianism stresses very much voluntary view and medical ideal, stresses spiritual motive role which is thought to be decided by the nature off medicine, the special profession, Humanitarianism never excludes utility and benefit. Medical humanitarinism is the unity on the conpemterary voluntary view and utilitarianism, and it is medical humanita-manism not utilitarianism to play roles in the medical practice.
ABSTRACT
Equitable,just and public allocation of health resources is an essential rule in organ transplantation.We reviewed the allocation principles of China and the United States of America and then proposed our strategy.First,establishing transplantation organ library is mainly depending on the medical organ transplantation society.Secondly,formulating the sorting and allocation rules of transplantation organ.Finally,upon the institutional review board,-ing surveillance and management institution to ensure equitable,just and public in allocation of health resources.
