[Objective]To evaluate the clinical efficacy of posterior pedicle screw instrumentation followed by anterior debridement and bone grafting through the lateral edge of the rectus abdominal muscle and retroperitoneal approach for the treatment of tuberculosis of the lower lumbar spine. [Methods]From June 2002 to January 2007,27 patients suffering from lower lumbar tuberculosis were treated with this technique.[Results]The surgical average time and amount of bleeding was 4.3 h and 438 ml respectively.The length of anterior incision was 5~7 cm.The average time and the amount of bleeding were 21 min and 48 ml respectively during the anterior lesion exposure.The follow-up period were 12~37 months,mean 17.3 months.The average preoperative,immediate postoperative,and final follow-up local lordotic angles of the affected segments were-2.1??4.0?,4.9??1.4?,3.7??3.0?.All patients had healed of disease and there was no recurrence at final follow up.Bony fusion was obtained in all patients.[Conclusion]Anterior exposure through the lateral edge of the rectus abdominal muscle and retroperitoneal approach is simple and less invasive.The spinal stability is achieved through short-segment pedicle screw fixation while reducing the sacrifice of additional motion segments.This technique is safe and effective for the treatment of tuberculosis of the lower lumbar spine.

BACKGROUND: The stratum corneum presents a significant barrier to transdermal drug delivery. Approaches to improve percutaneous absorption of drugs have included iontophoresis and skin penetration enhancers. Oleic acid has been studied as a skin penetration enhancer for drugs, primarily via its action mainly on the stratum corneum lipid structure. OBJECTIVE: The purpose of this study was to assess the interaction between oleic acid and stratum corneum lipids in vivo. METHODS: Male hairless mice were treated topically with oleic acid. Barrier function was assessed by transepidermal water loss measurement and ultrastructural observation with ruthenium tetroxide (RuO₄) staining. RESULTS: Oleic acid in propylene glycol had a profound effect on epidermal barrier function and was found to be concentration dependent. Moreover, ultrastructural examination with RuO4 post-fixation demonstrated that there were marked alterations in the stratum corneum lipid structure. CONCLUSION: This study provides direct evidence that oleic acid increases the epidermal permeability through a mechanism involving the stratum corneum lipid membrane perturbation via the lacunae formation within the stratum corneum.

BACKGROUND:The three-dimensional structure of acupoint anatomy was integrated into the teaching of acupuncture manipulation. Combined with the implementation and application of the acupuncture and moxibustion in digital virtual human, it can greatly improve the teaching effect and learning interest. OBJECTIVE:To investigate the acupuncture virtual human with integration of virtual reality force feedback technology and tissue deformation. METHODS:Using virtual reality technology, with computer as the core, we generated a specific range of virtual environment with realistic visual, auditory and tactile integration, col ected clinical expert acupuncture technique, matched the sensing equipment that can reflect the intensity, displacement and speed sensing of acupuncture. Based on image segmentation of virtual human, we constructed human tissue mechanics model, built virtual acupuncture-force-feedback system, and faithful y transmitted to the operator by a force feedback device. On one hand, based on VOXEL-MAN virtual human development platform, we finished the three-dimensional browser redevelopment of the science of acupuncture and moxibustion of Shu acupoint, which provided visual perception for people. On the other hand, based on modern biomechanics theory, we established models by graphics and image processing technology and force feedback technology. The stress process of the structure of each layer in the acupuncture point area was given to people in a sense of touch by the manner of virtual reality and force feedback. RESULTS AND CONCLUSION:With the man-machine interactive operation platform of virtual acupuncture force feedback system, operator could see the dynamic process of acupuncture needle into human body, and could feel the real counterforce in the control terminal of force feedback instrument. By operating acupuncture needle in virtual environment of force feedback instrument, acupuncture was performed in virtual human. The system meets the two requirements:the feedback changes produced by tissue interaction were similar to real acupuncture feedback force data measured by instrument. The acupuncture needle entered into different tissues, a sense of power changed significantly;there was progressive feeling with different layers, reaching a realistic experience. During the whole training, the image was smooth;virtual needle was responsive, which better meets the requirements of virtual reality.

Objective To investigate the analgesic effect of oxysophoridine(OSR)and the influence of verapamil(Ver)on the antinociception of OSR when two drugs were co-administrated in mice.Methods The number of writhing within 15 min after ip different doses of OSR was observed in painful mouse mo- dels caused by acetic acid.The hot plate method was used to assess nociceptive sensitivity of CaCl_2 and Ver before ip OSR.Nitric oxide(NO)in serum was measured by spectrophotometry.Results The number of writhing was decreased and the latency of licking the hind paws was prolonged in a dose-dependent manner after ip OSR.The antinociception of OSR could be antagonized by CaCl_2 and enhanced by Ver.No inter- ference was detected in serum volume of NO.Conclusion These results suggest that OSR can antagonize the acute pain caused by acetic acid and hot plate in a dose-dependent manner in mice.Calcium channel blocker could enhance the effect of OSR.
