[Objective] To summarize ZHANG Xichun's clinical experience on using white tiger and ginseng soup.[Methods] Put ZHANG Xichun's document in order to analyze the effect of ginseng in this part, the treatment of disease should be added in the conditions of the white tiger soup, in the attention to details. [Results] He studied and researched the Shan Han Lun, in combination with his own experience, thought that the ginseng added into the white tiger soup, not only sweating or emesis or purgation, bus also feeble pulse. Should be taken into account the composite factors such as age and physical etc. And must join ginseng in the post partum. Put forward the theory of the Shaoyin of febrile disease. Breaking the postpartum avoid is used for cold. Remove the heat of Yangming to treat lung disease. Treat the febrile disease of pregnancy. He also thought Yangming and feeble pulse should use white tiger and ginseng soup to treat the pulse, then to purge. He was carefully to ask patients'illness. He combined symptoms with pulse condition, comprehensive analysis to both pulse manifestation and symptoms, paid attention to decocting medicine and taking medicine also. [Conclusion] White tiger and ginseng soup mostly treats the cold or warm into the Yangming disease. The basic pathogenesis is the heat in Yangming. Break the cold attack, warm disease from those. To promote the clinical application of white tiger and ginseng soup, through the clinical details in order to improve curative effect, significant contribution to the clinical application of white tiger and ginseng soup.

OBJECTIVEThis research aims to study the changes in pain threshold and glial cell line-derived neurotrophic factor (GDNF) in a Sprague Dawley (SD) rat model oftrigeminal neuralgia.

METHODSA total of 36 male SD rats were randomly divided into three groups: operative, sham-operative, and control. In the operative group, a chronic constriction injury (CCI) was caused by placing loose chromic gut ligatures around the right infraorbital nerve (ION). In the sham-operative group, the right ION was subjected to the same procedure, but without ligation. In the control group, the right ION was not subjected to any treatment. The pain thresholds of the three groups were recorded at different times after the operation. The GDNF expression in each group was analyzed via immunohistochemical staining.

RESULTSAn allodynia to mechanical stimulation in the region of the ligated ION was observed starting on the 2nd week after operation. Pain thresholds started to increase gradually from the 6th week and returned to the original level at the 10th to 12th week after operation. Cells that expressed the GDNF markedly increased in number in the operative group with changes observed at different times.

CONCLUSIONWe use chronic constriction injury to the infraorbital nerve (CCI-ION) to establish a trigeminal neuralgia-like animal model in SD rats. GDNF may play a role in regulating pain by promoting the restoration and regeneration of nerve fibers.

BACKGROUND:With the rapid development of medical technology, computer image technology and the urgent needs of computer-aided clinical teaching, the application of virtual reality technology in oral and maxilofacial anatomy has become an issue of concern. OBJECTIVE:To summarize the application of virtual reality technology in oral and maxilofacial anatomy, thereby providing the better methods for clinical and basic research of oral medicine, laying the foundation for building the digital repository, and realizing the informatization and networking construction. METHODS:A computer-based retrieval was performed by the first author in the CNKI and PubMed databases to search papers related on the virtual reality technology applied in oral and maxilofacial anatomy published between January 2004 and December 2014, using the key words of “tissue engineering, virtual reality, oral and maxilofacial anatomy, digital, 3D reconstruction, multimedia, teeth, skul” in Chinese and English, respectively. According to inclusion and exclusion criteria, 52 papers were included in the final analysis. RESULTS AND CONCLUSION:The application of virtual reality technology in oral and maxilofacial anatomy mainly includes 3D digital model and virtual digital database of human body. 3D medical reconstruction software includes 3D-Doctor and Minics that support the original data sources including continuous fault anatomical images, varieties of image data and 3D scanning data. A variety of virtual reality technologies can successfuly reproduce the tooth, dentition and oral and maxilofacial anatomy, laying the foundation for building the virtual reality platform in oral clinical application and teaching.

BACKGROUND:Because the content of oral and maxil ofacial anatomy is various and complex, only the traditional way of multimedia cannot display the anatomical structures from multi-angle and al-round. The development of virtual reality technology in oral and maxil ofacial anatomy of three-dimensional reconstruction research is rapid, causes the attention of many scholars, and has become a hot spot. OBJECTIVE:To develop a three-dimensional digital model of tooth, dentition and skul , and establish a multimedia database of oral and maxil ofacial anatomy to facilitate network sharing and information dissemination so as to provide new method for teaching of basic and clinical oral medicine. METHODS:Extracted teeth with intact crown and root, dentition and skul were chosen. Each specimen was taken at horizontal and vertical direction by the camera in the center of turntable. Al the images obtained were treated using Photoshop CS5 for dressing and compression. The image data were input into The VR Worx system, fol owed by parameters and hotspots setting and the compression. Final y, the three-dimensional digital models were reconstructed and output with QuickTime VR format into disk. RESULTS AND CONCLUSION:Three-dimensional digital models of tooth and skul were constructed with photography and the VR Worx 2.6 software, which could faithful y reproduce the anatomical characteristics of teeth, dentition and skul s, and facilitate researchers to rotate and scale for observation. Also, it was easy for hotspot-marking. On the platform of digital photography and The VR Worx software, it is feasible to establish the three-dimensional digital model of tooth and skul . This approach is the entity reconstruction, and the reconstructed model appears clear, vivid, and is easy to be saved and promoted.

AIM: To investigate the effect of testosterone with varied concentrations on the fibr inolysis activity of HUVEC and its mechanism. METHODS: Human umbilical vein endothelial cells (HUVEC) were cul tured as recommended. After confluence, the cultures were treated with testoster one(3 ?10 -10, 3?10 -9, 3?10 -8,3?10 -6, 3?10 -5 m ol/L) , and the control confluent cells were cultured in the same medium witho ut steroid. MTT experiment was repeated for 72 hours to investigate each groups' cell proliferation. The tPA and PAI-1 antigen levels were assayed with ELISA K its. Then with HUVEC incubated in androgen receptor antagonist (flutamide) 3 hou rs previously, the experiment was repeated. RESULTS: Testosterone at physiologic or lower concentrations (3 ?10 -10 to 3?10 -8 mol/L ) stimulated the secretion of tPA by HUVEC (P

AIM: To investigate the action of testosterone on atherosclerosis in a rabbit model. METHODS: 37 male cholesterol-fed rabbits were divided into five groups: castration group: castrated rabbits without exogenous testosterone administration; testosterone Ⅰ group: castrated rabbits with exogenous testosterone 0.25 mg?kg -1?d -1; testosterone Ⅱ group: castrated rabbits with exogenous testosterone 2.5 mg?kg -1?d -1; testosterone Ⅲ group: castrated rabbits with exogenous testosterone 12.5 mg?kg -1?d -1. The sham operation group was also set. Three months later, the levels of testosterone, blood lipids (including TG, HDL-C, LDL-C), PAI activity, nitric oxide (NO) content, endothelin (ET), angiotensin Ⅱ (AngⅡ) in blood were detected. RESULTS: It showed that testosterone in castration group was the lowest. There was no significant difference of TG or LDL-C between castration group and the other four groups. HDL-C in castration group was lower than that in other four groups. NO content of castration group was lower than that in others, but PAI activity, ET and AngⅡ concentration were higher than that in other groups. CONCLUSION: Testosterone is a protective factor against atherosclerosis in male rabbits.

ObjectiveTo measure the displacement parameters of the femoral head in space through CT three-dimensional reconstruction so as to re-understand impacted femoral neck fractures.MethodsFifty patients with impacted femoral neck fractures were included in the study.There were 17 males and 33 females.Bilateral proximal femurs of each patient were scanned by spiral CT preoperatively.Then these primitive CT data were reconstructed by Mimics 10.01 software.Registered the normal femur and fracture mirror model,the registered mirror model was generated a new mask in the CT cross-sectional images,marked key points in the masks and measured the displacement parameters of femoral head with three-dimensional measurement technology.ResultsIn the impacted femoral neck fractures,the femoral head displacement angle was 17.17°±10.40°,70％(35/50) of the patients had femoral head rotation angle was at 10° to 35°,and 30％(15/50) of the patients had femoral head space displacement more than 20°.The average displacement distance of femoral head center and the deepest point of fovea capitis were(6.49±3.60) mm and(10.42±5.92) mm,respectively.A high proportion of the impacted femoral neck fractures had a large of displacement in the three-dimensional space.It is not scientific to equal impacted femoral neck fractures to undisplaced fractures.ConclusionThree-dimensional reconstruction and digital measurement is a precise,efficient and convenient method for the measurement of femoral head displacement parameters in femoral neck fracture patients.The classic Garden classification for impacted femoral neck fractures has certain defects and limitations.Clinicians should re-understand impacted femoral neck fractures and choose more reasonable treatment.
