BACKGROUND:Double inferior vena cava (DIVC), usually found at routine autopsies, is rare in the clinic. It has been described in numerous reports over the years since Adachi first depicted it in 1940. But all these reports were based on two-dimensional (2D) observation, and no three-dimensional and animated images reported. OBJECTIVE: To observe and establish the digital visible models of the structure of DIVC of the Virtual Chinese Human Male (VCH-M) Ⅲ.DESIGN: Repetitive measurement design by taking VCH-M Ⅲ as the subjects.SETTING : Department of Traumatic Orthopedics and Anatomy, Nanfang Hospital Affiliated to Southern Medical University.MATERIALS: The experiment was conducted in Southern Medical University from February 2006 to May 2006. The cross-sectional images of fresh tissues from VCH-M Ⅲ dataset were reviewed and 1 060 serially-sectioned slices of VCH-M Ⅲ, from the 2 600th slice to the 3 660th were taken as the source for the 3D models in our study.METHODS: Cross-sectional images of fresh tissues from the VCH-M Ⅲ dataset were reviewed and the structures of the DIVC were confirmed on a section-by-section basis. 3D computerized reconstructions of DIVC and its adjacent structures were generated from these data using Arnira 3.1 (TGS) imaging software.MAIN OUTCOME MEASURES: Cross-sectional images and 3D reconstruction of VCH-M Ⅲ.RESULTS: The cross-sectional images of the VGH-M Ⅲ could fairly display the main structure of DIVC. The digitized model of brachial plexus offers unique insights into the abnormity anatomy of DIVC.CONCLUSION: The VCH-M Ⅲ dataset can provide complete and accurate data of DIVC.

Periosteal autograft from different sources have been used to repair 1.5cm bone defects of radius in 10 rabbits.On the left side,sharp-dissected grafts were implanted and the animals were sacrificed 4,8,14,30 and 60 days after operation.Bone formation was studied with X-ray and histologic technique.The results showed that the way of sharp-dissecting can preserve the periosteum completely,and good bone formation was found in this group.It suggested that the sharp-dissecting of the periosteum is the important key for periosteal graft.

Packing the nose after septoplasty is common practice. The use of postoperative packing has been proposed to reduce the dead space between the subperichondrial flaps and minimize postoperative complications such as hemorrhage, septal hematoma, and formation of synechiae. Additionally, postoperative packing is thought to stabilize the remaining cartilaginous septum and minimize persistence or recurrence of septal deviation. Despite these theoretic advantages, evidence to support the use of postoperative packing is lacking. Additionally, nasal packing is not an innocuous procedure. The use of nasal packing actually cause these complications such as postop- erative pain, mucosal injury, bleeding, worsening of breathing due to sleep disorders, and postoperative infections. Routine use of anterior nasal packing after septoplasty should be challenged for not presenting proven benefit. As alternatives to traditional packing, septal suturing, septal stapler and fibrin glue have been used recently. The purpose of this article is to summarize the progress of traditional packing to no packing after septoplasty.

Aim: To preliminarily investigate the antioxidant activity of the acidic exopolysaccharide(EPS-A) from cultivated Cordyceps sisnensis in vitro and in vivo. Methods: PC12 cells were injured by H_2O_2 after the cells were treated with different doses of EPS-A for 6 h, and then the levels of malondialdelyde( MDA) and superoxide dis-mutase (SOD) in PC12 cells were determined. H22 cells were inoculated into the right oxter of each mouse after ICR mice were treated with EPS-A for 7 days, and tumor-bearing mice were treated with EPS-A for 7 days. MDA level and SOD activity in liver, brain and serum were assayed, and tumor weight of each mouse was measured as well. Results: EPS-A significantly decreased the production of MDA and increased SOD activity in H_2O_2-injured PC12 cells. Moreover, EPS-A inhibited H22 tumor growth in mice, in which the level of MDA in liver and brain was reduced, and SOD activity in liver, brain and serum was enhanced. Conclusion: EPS-A exhibited antioxidant activity in cell cultures and mice.

Background and purpose: About 20 cases of BML have been reported in the literature,they occurred in females with history of uterus leiomyoma.BML appears as a histopathologic benign smooth muscle tumor located far from the uterus,often in the lungs.Firstly,it should be confirmed as originating from smooth muscle by immunohistochemistry,Secondly,its primary tumor should be confirmed as benign,with mucoid degenenation,it also should be distinguished from myxoid leiomyosacroma.Methods:We report a case of benign metastasizing leiomyoma,study its clinical,histopathologic and immunohistologic features,discuss the diagnosis and differential diagnosis and give a review of the related references.Results:The case occurred in a forty-two year old female who was found to have bilateral lung nodules after hysterectomy of her uterus leiomyoma six years ago.An open lung biopsy revealed the nodules to consist of proliferating smooth muscle cells with a histopathologic feature similar to her uterus leimyoma,consistent with the diagnosis of BML.Positive staining of estrogen and progesterone receptors was detected in both the uterus leiomyoma and the metastasizing lesions.No significant increase or enlargement of the lung nodules were found seven months after the operation with no therapy except taking Chinese traditional medicine.Conclusions:BML is a rare entity usually occurring in females with history of uterus leiomyoma.It appears as a histopathologic benign smooth muscle tumors distant from the uterus.It is hormone dependent and progresses slowly.

Forty patients who underwent sub-total gastrectomy were divided into four groups, one of them for comparison, the other three groups received 10%, 30% and 100% branched-chain amino acid (BCAA) respectively. The results showed that in BCAA-10 and BCAA-3H group, negative balance was partially corrected, but in BCAA-10 group nitrogen remained an obvious negative balance on the 3rd postoperative day. There were more than ten of plasma AA lower than preoperative day in these two groups. In BCAA-30 group, after surgery, negative nitrogen balance was significantly corrected, and changes of plasma AA had no statistic significance compared with that before operation.Creatinine of urine had no significant difference between each group.In BCAA-30 group, transferrin (Tf) was increased compared with that before operation. It is suggested that the protein synthesis is corrected but the catabolism is not restrained.BCAA may play a regulatory role in muscle protein metabolism, BCAA can serve as fuel substrate to promote synthesis and reduce breakdown of muscle protein to correct negative nitrogen balance.Application of large quantities of BCAA should be based on isotonic AA solution.

Objective To explore the characteristics of changes in temperature and stiffness within the microwave-induced ablation region.Methods A type of Thy-ablation microwave antenna was used upon a design of various combination of ablation duration and power to induce heated region in samples of fresh porcine liver.Three special sites were set to assess the corresponding temperature and stiffness in each heated region.The temperature was continuously measured by using electronic thermometer with microwave on going,while stiffness was determined 5min after the ending of ablation by using real-time ultrasonic elastography,strain ratio,a quantitative indicator.Results The SR values and temperature determinations decreased progressively from the central to the peripheral area of the heated region.There was a linear regression between the temperatures (X) and SRs (Y),with Y =0.666 X-37.17.A significant correlation exists between X and Y,with the correlation coefficient being 0.956(P ＜0.001).The stiffness and temperature at the central sites are variable with the changes of both ablation time and power,but little changed at the peripheral sites of heated-region,which we name a phenomenon due to the ending effect of microwave propagation.Conclusions Temperature and stiffness increase considerably following microwave radiation but they are heterogeneously distributed within the ablated region in porcine liver.The characteristic gradient changes are confirmed of both temperature and the elasticity.It is presumable that good recognition and understanding and full utilization of these characteristics are conducive to reasonable control of tumor microwave ablation therapy.
