OBJECTIVETo explore effectiveness and safety of segmental anterior cervical decompression in treating multi-level cervical myelopathy.

METHODSTwenty-four patients with four levels of cervical myelopathy were treated with segmental anterior cervical decompression (reservation of middle vertebrae, bone graft and plate-screws fixation). Among patients, there were 15 males and 9 females aged from 47 to 75 (averaged 57.9) years old. Preoperative, postoperative at 1 week and the latest following-up AP and lateral X-rays were used to observe bone union, displacement of implant, adjacent segment degeneration, changes of Cobb angle of fusion segment. JOA scoring were applied for evaluate recovery of nerve function.

RESULTSAll operations were completed successfully, 2 cases ocurred hoarseness, and improved after treated symptomatically. Nineteen patients were followed up from 3.1 to 5.3 years with an average of 3.9 years. Bone union time ranged from 3 to 7 (averaged 4.5) months. No screw loosening and displacement occurred. Nine patients occurred titanium mesh subsidence in different degrees, and 4 of them subside >3 mm; four patients ocurred adjacent segment degeneration. Postoperative Cobb angle of fusion segment at 1 week (10.40±2.94)° was improved from preoperative (5.76±4.16)°, but decreased at the latest follow-up (8.57±2.82)°, and had significant meaning compared with preoperative (P<0.01). JOA score at the latest follow-up (14.6±1.1) was higher than that of before operation (8.2±1.9), and had siginificant differences (P<0.01).

CONCLUSIONSegmental anterior cervical decompression for the treatment of multilevel cervical myelopathy has a high clinical operability, and plays an important role in recovering cervical curvature and nerve function based on completely decompression.

On account of the dense cuticles of the fresh stem and the light, hard and pliable texture of the dried stem, Dendrobii Caulis is difficult to dry or pulverize. So, it is very important to the ancient doctors that Dendrobii Caulis should be properly treated and applied to keep or evoke its medicinal effects. The current textual research results about the preliminary processing, processing and usage methods of Dendrobii Caulis showed that: (1) In history the clinical use of fresh or processed Dendrobii Caulis as teas and tinctures were very common. (2) Its roots and rhizomes would be removed before using. (3) Some ancillary approaches were applied to shorten drying times, such as rinsing with boiling mulberry-ash soup, washing or soaking with liquor, mixing with rice pulp and then basking, etc. (4) According to the ancients knowledge, the sufficient pulverization, by means of slicing, rasping, hitting or pestling techniques, was necessary for Dendrobii Caulis to take its effects. (5) The heat processing methods for Dendrobii Caulis included stir-baking, stir-frying, steaming, decocting and stewing techniques, usually with liquor as an auxiliary material. Among above mentioned, steaming by pretreating with liquor was most commonly used, and this scheme was colorfully drawn in Bu Yi Lei Gong Pao Zhi Bian Lan (Ming Dynasty, 1591 CE) ; moreover, decocting in advance or long-time simmering so as to prepare paste products were recommended in the Qing Dynasty. (6) Some different processing programs involving stir-baking with grit, air-tightly baking with ondol (Kangs), fumigating with sulfur, which appeared in modern times and brought attractive outward appearance of the drug, went against ancients original intentions of ensuring drug efficacy.

Biotransformation of bioactive natural leading compounds is a kind of bioprocess in which the structure of the added bioactive natural leading compounds could be modified by biocatalysts(e.g.,enzyme,microbial,plant and animal cells) in order to produce high efficient and low toxicity compounds.The biotransformation purpose of the known bioactive natural leading compounds is to improve its efficiency,or reduce its toxicity,or improve its solubility and bioavailability.The trace and high-valued bioactive natural leading compounds also could be produced by the biotransformation,and the biotransformation of bioactive natural leading compounds is still helpful to study the mechanism of drug metabolism.The current focus of the biotransformation of bioactive natural leading compounds is on the compounds of steroid,quinine,flavone and terpene,and some important biotransformation process has been successfully screened out.Fundamental research should be done in the following fields,such as the biotransformation mechanism of bioactive natural leading compounds,biotransformation process engineering,and the efficiency evaluation of bioproducts produced by biotransformation.The latest biotechnology(e.g.,directed evolution of biocatalyst,combinatorial biotransformation,non-aqueous biotransformation,high throughput screening) should be introduced to the biotransformation of bioactive natural leading compounds,which will boost its fast development.

Accurate area assessment of a burn injury and its treatment according to its depth of injury are the foundation of burn treatment due to its complexity, and various techniques and methods have been employed to solve these problems for many years. As the demand of modern medicine calls for individualized and precise therapeutic measures, it is clear that the traditional diagnostic and treatment measures are insufficient. The flourishing development of three-dimensional (3D) technology seems to provide new research approaches and technical opporturities for burn surgery. A series of techniques such as 3D model, 3D scanning, and 3D printing may be promising in advancing burn surgery through basic research to achieve rational clinical applications in the future. In this paper, the applications and achievements of 3D technology in burn surgery in recent years are summarized.

Objective To investigate the diagnostic value of the recombinant surface antigen 1 (rSAG1) in immunodiagnosis of toxoplasmosis. Methods Isopropyl β-D- 1 -thio-galaetopyranoside (IPTG) was used to induce the expression of recombinant plasmid pET28a-SAG1 of Escherich coli(pET28a-SAG1/BL21 ). The expression products (rSAG1) of pET28a-SAG1/BL21 were identified by Western blotting. The serum of mice infected with Toxoplasma gondii tachyzoites, normal mouse serum and the serum from 10 toxoplasma gondii patients were used as primary anti-Toxoplasma gondii antibodies, and the rSAG1 gene products were identified by Western blotting, by which the diagnostic value of rSAG1 in Toxoplasmosis was compared. Results After induction and purification, rSAG1 protein was obtained and its relative molecular mass was 38.5 × 103. The fusion protein could be recognized by the serum of mouse infected with Toxoplasma gondii tachyzoites, rSAG1 of expression products of surface membrane antigen SAG1 gene from Toxoplasma Gondii could be detected in 4 cases from 10 patients by Westem blotting.Conclusion The rSAG1 has a potential value in the immunodiagnosis of Toxoplasmosis.

Objective:To observe the clinical efficacy of acupuncture at abdomen acupoints plus tuina for lumbar intervertebral disc herniation (LIDH).Methods:A total of 70 patients with LIDH were randomized into an observation group and a control group,with 35 cases in each group.The observation group was treated with acupuncture at abdomen acupoints plus tuina,while the control group was treated only with tuina treatment.The clinical efficacy was observed after one course of treatment.Results:The cure rate and the total effective rate of the observation group were 83.3％ and 96.7％,respectively.The cure rate and the total effective rate of the control group were 39.4％ and 78.8％,respectively.There were significant differences in the cured rate and the total effective rate between the two groups (both P＜0.05).There was no significant difference in Japanese Orthopedic Association (JOA) score between the two groups before treatment (P＞0.05).After treatment,the JOA scores of both groups increased significantly,and the intra-group differences were statistically significant (both P＜0.05);the JOA score of the observation group was significantly higher than that of the control group (P＜0.05).Conclusion:Acupuncture at abdomen acupoints plus tuina has a better therapeutic effect than tuina alone in the treatment of LIDH.
