There should be confusion about diagnosis and treatment for multiple segments cervical myelopathy in some respects. The author reviewed the literature and combined with clinical experience, proposed a new classification for cervical myelopathy according to responsibility segment areas, which dividing into single segment,double segments (continues or jumping type), multi-segment (≥ three segments). The responsible segments determination is the premise of diagnosis and also a key to determine surgical decompression segment. Decompression only according to imaging was not desirable, surgical segment should mainly relies on clinical, imaging, electrophysiological and comprehensive analysis to avoid surgery range expansion. Surgical approach and procedures are still the focus and hotspot of cervical myelopathy treatment, and no treatment standards and corresponding guidelines to consult. The author proposes that surgical approach should advocate the individual, and surgical procedure should follow simple instead of complicate, anterior and posterior combined decompression is not necessary in most cases, and anterior and posterior fixation are not need.

Objective To evaluate the effectiveness of TCM combined with western medicine for advanced gastric cancer.Methods We retrieved literatures of randomized controlled clinical trials related (from January 1991 to June 2012) to the use of TCM combined with western medicine treatment for advanced gastric cancer and made meta-analysis including:the effectiveness,Kamofsky scores and publication bias.Results 44 papers (including 3088 AGC patients) were included.Meta analysis suggested a difference between the treatment group and the control group in effectiveness (Z＝ 6.12,P＜ 0.01),and K score (Z＝ 3.31,P＜0.01).The effectiveness of the reatment group and the control group are 97.8％ and 73.4％ respectively.Conclusion The combined treatment resulted in an improved quality of effectiveness and Kamofsky scores.

With the progresses of the research on "Digital Human", more and more information has been needed for the setting up of the three-dimensional digital models of human organs. In the present paper, based on the method of block mapping with a normal-style bump mapping method, we normalized the vector of the surface of the models, computed offset of the texture coordinates and added to them. The projection of the coordinates to the tangential space complemented the disturbance to the vector of models' surface. The method was proposed with bump texture mapping on the surface of the biological models of organs to improve the impression of the visualization of the organ models and to enhance the sense of reality of the models.

Objective To investigate the effects of Thomas solution in combination with nitroglycerine of different concentrations on rat cardiac preservation for 8 h. Methods Thirty Wistar rats were selected,and Langendorff heart perfusion models were established.Rats were randomly divided into Thomas solution group,Thomas solution+4?10-6 mol/L nitroglycerine group and Thomas solution+4?10-5 mol/L nitroglycerine group(n=10).After hypothermic preservation(4 ℃)for 8 h,the cardiac function of each group was determined.Tissues of left ventricular wall were obtained,and changes of myocardial ultrastructure were observed by electron microscopy. Results Compared with Thomas solution group,the cardiac function was significantly improved and the myocardial ultrastructure injury was less severe in Thomas solution+4?10-5 mol/L nitroglycerine group after hypothermic preservation(4 ℃)for 8 h,while there was no significant difference in myocardial ultrastructure injury and cardiac function between Thomas solution group and Thomas solution+4?10-6 mol/L nitroglycerine group. Conclusion Thomas solution in combination with 4?10-5 mol/L nitroglycerine can significantly improve the preservation effects for isolated hearts in rats.

Smoke water and distillation liquid were used to treat the seeds of Trichosathes kirilowii and to study the effects of smoke water and distillation liquid on the seed germination and seedling growth of T. kirilowii. The results showed that germination rate, germination index and germination vigor of T. kirilowii all were significantly improved with the treatment of SW and DL treatment. The activity of α-amylase were significantly increased with the treatment of SW and DL at 1:2,000. SW and DL treatment showed no significant effects on the activity of SOD. The activity of POD were markedly enhanced under the treatment of SW (1:000) and DL (1:2,000). CAT activity were increased with the treatment of SW and DL at 1:2,000 while were inhibited by SW and DL at 1:500. Seedling height and root length were increased with the treatment of SW and DL (1:1,000, 1:2,000). SW and DL treaments improved the content of chlorophyll, and moreover with the concentration of SW and DL, the stimulatory were also increased. This work demonstrated that smoke water and diatillation liquid at 1:2,000 could stimulate the seed germination and seedling growth of T. kirilowii, and it provided the references for the study of seed germination technology.

Objective To analyze the clinical manifestations and possible gene mutation sites of Chinese patients in order to improve the clinician's understanding of CHARGE syndrome. Methods Clinical data were collected and blood samples were obtained from the proband of CHARGE syndrome and their relatives. The peripheral blood DNA was extracted and sequenced by PCR amplification. Mutation sites were verified by Sanger sequencing. Results For the first proband, a heterozygous mutation was detected in the intron 10 of CHD7 gene. His parents and brother did not have mutation. For the second proband, total repeat sequence in exon 7 of CHD7 gene was detected. His father carried the same mutation and his mother did not have mutation. Conclusion For the patients who are diagnosed with CHARGE syndrome based on the clinical manifestations, genetic mutation detection should be proceeded. It is useful for studying possible genetic pathogenesis and enhancing the awareness of clinicians.

More ACL tissue were preserved in ACL reconstruction with remnant-preserving than in classic ACL reconstruction. Some studies showed the results in promoting biological healing after undergoing these two procedures, while other studies did not find the clear advantages in clinical outcomes comparing with the classical ACL reconstruction. There were still some controversies in clinical significances for these complicated ACL reconstructions with remnant-preserving. The article summarized recent original studies about ACL reconstruction with remnant-preserving, as well as reviewed the biological characteristics, classification, procedure and clinical outcomes for these two techniques.

Objective To investigate the causes of pancreatic injury after autologous liver transplantation in rats. Methods Forty-two SD rats were randomly divided into post autologons liver transplantation 1-hour group, 6-hour group, 12-hour group, 24-hour group, 48-hour group, 72-hour group and sham group (6 rats per group). The plasma concentrations of amylase and lipase were measured to assess pancreatic exocrine function. The histomorphological changes of pancreatic tissue were studied under optical and electron microscopes. All data were analyzed via one-way ANOVA. Results The plasma concentrations of amylase and lipnse in post autologous liver transplantation 1-hour group were significantly higher than those in sham group, and they gradually increased as time passed by. The plasma concentrations of amylase and lipase reached peak at hour 48, after which they decreased gradually. There was a significant difference in the plasma concentration of amylase and lipase among the 7 groups (F = 538.622,489.417, P < 0.05). Acute edematous pancreatitis was observed 1 hour after autolognus liver transplantation, and acute hemorrhagic necrotic pancreatitis was observed 6 hours after transplantation. The degree of injury reached a peak 48 hours after transplantation. The number of mitochondria was increased, and endoplasmic reticulum and Golgi apparatus were swollen 1 hour after transplantation, and the area, perimeter, specific surface area and mean gray value of mitochondria were (312±40) mm~2, (80.3±3.8)mm, 0.332±0.039 and 113±11, respectively. As time passed by, the injury of the pancreatic cells was aggravated and autophagosomes were observed. The injury was most severe 48 hours after transplantation, and the area, perimeter, specific surface area and mean gray value of mitochondria were (466±7) mm~2, (108.8±3.7) mm, 0.298±0.009 and 195±12, respectively. There were significant differences in the specific surface area and mean gray value among all the groups (F = 9.322, 76.560, P < 0.05). Conclusion The pancreatic injury after autologous liver transplantation is related to the energy metabolism of the pancreatic cells induced by hypoxia.
