Objective To investigate role of reverse digital artery island flap combined with dig- ital nerve end to side anastomosis.Methods Reverse digital artery island flaps were used for recon- struction of 65 fingertip defects in 57cases,in which the restoration of the flap sense was attained via dig- ital nerve end to side anastomosis.Results After primary repair,all flaps survived,with good appear- ance and wear-resisting as well as satisfactory two-point discriminations.Conclusion Digital artery re- verse island flap combined with digital nerve end to side anastomosis is a simple and effective procedure for repair of finger defect.

Objective To evaluate the respiratory movement of the both lungs with four-dimensional CT(4DCT), and determine the optimal respiratory phase series CT images for radiation dose calculation. Methods From November 2005 to November 2006,thirty patients with lung cancer who received 4DCT scan were enrolled,including 15 left and 15 right lung cancer cases,25 men and 5 women. The media age was 55 (35-78) years old. After 4DCT scanning, the image was treated with Advantage 4D workstation,and then transmitted into Pinnacle station( Adac 7.4). The both lungs were automatically outlined using Pinnacle station with CT recognition value of-900 to-200 Hu. Then-the same physician examined the unreasonable parts and revised them. After the delineation was completed,the volume of 10 respiratory phases of lung was obtained. Results The average respiratory phase in inspiratory and expiratory phases was 78.87%±2.71% and 26.32%±3.17% in the tumor located lung,77.55%±2.81% and 24.73%±2.55% in the healthy lung. The maximum and minimum mean volume was 106.48%±3.00% and 94.23%±2.78% in the tumor located lung,107.47%±2.43% and 93.65%±2.32% in the healthy lung. The volume at the end of inspiratory and expiratory was 106.43%±3.07% and 94.63%±2.71% in the tumor located lung, 107.37%±4.62% and 93.98%±2.34% in the healthy lung. Conclusions The series CT images scan on 20% ,30% and 80% respiratory phases are reasonable for radiation dose calculation. The maximum and minimum average lung volumes are almost equal to those at the end of inspiratory and expiratory.

Objective To evaluate the localization of mitral valvular(MV)prolapse by transthoracic echocardiography(TTE),transesophageal echocardiography(TEE)and explore the interrelationship between the different subregions of MV prolapse and mitral regurgitation(MR).Methods Total of thirtythree patients with MV prolapse and more than moderate MR were included.TEE was used to further judge the location of scallop lesions and the result of both TTE and TEE were compared with the surgical findings respectively.The relationship between the different subregions of MV prolapse and MR was analyzed.Results Compared with the surgery findings,the accuracy rate of TTE and TEE in diagnosis of MV prolapse was 100％ qualitatively,80％ for TTE and 94％ for TEE in localizing the diseased region with the anterior and posterior MV,the result of TEE was significantly different from TTE(P＜0.05).MR level was related to the location of MV prolapse.Conclusions Compared with the TTE,TEE had more advantages in localizing the position of the MV prolapse.Mitral regurgitation is related to the location of MV prolapse.

BACKGROUND: High mobility group box 1 protein (HMGB1) is a highly conserved, ubiquitous protein in the nuclei and cytoplasm of nearly all cell types. HMGB1 is secreted into the extracellular milieu and acts as a proinflammatory cytokine. In this article we reviewed briefly the cellular immune response mediated by HMGB1 in inflammation and sepsis. METHODS: This systemic review is mainly based on our own work and other related reports. RESULTS: HMGB1 can actively affect the immune functions of many types of cells including T lymphocytes, regulatory T cells (Tregs), dendritic cells (DCs), macrophages, and natural killer cells (NK cells). Various cellular responses can be mediated by HMGB1 which binds to cell-surface receptors [e.g., the receptor for advanced glycation end products (RAGE), Toll-like receptor (TLR)2, and TLR4]. Anti-HMGB1 treatment, such as anti-HMGB1 polyclonal or monoclonal antibodies, inhibitors (e.g., ethyl pyruvate) and antagonists (e.g., A box), can protect against sepsis lethality and give a wider window for the treatment opportunity. CONCLUSION: HMGB1 is an attractive target for the development of new therapeutic strategies in the treatment of patients with septic complications.

OBJECTIVETo study the change in expressions of nerve growth related protein (GAP-43) and neurofilament (NF) after experimental injury of spinal cord, and the regulatory effect of Chinese medicine Suifukang (SFK) on them.

METHODSForty-eight from the 54 selected adult SD rats were established into spinal cord injury model by making hemitransection at the T12 level, and randomly divided into two groups, the SFK group feed with SKF contained liquor and the model group feeding with equal volume of saline. The another 6 rats were untreated and taken as the normal group. All rats were sacrificed in batches at different time points of day 3, 7, 15 and 30 after modeling. The spinal cord was obtained for determining the optic density (OD) of positive expression of GAP-43 and NF with immunohistochemical stain by microscopic and semi-quantitative image analysis.

RESULTS(1) OD of NF in the model group was obviously decreased on day 7, showing significant difference to that in the normal group and that in the SFK group (P < 0.05), and it maintained at low level after then, while the OD of NF in the SFK group was obviously higher than that in the model group (P < 0.05), it arrived the peak on day 15 and then dropped near the level in the normal group on day 30; (2) OD and of GAP-43 in the model group obviously decreased on day 3 (P < 0.05), showing significant difference to that in the normal group (P < 0.05), then it returned to approach to the level in the normal group on day 7. It was higher in the SFK group than in the model group on day 3, and maintained the high level to day 7, at that time, it was still higher than that in the model group and also higher than that in the normal group (P < 0.05).

CONCLUSIONSFK can promote the repair and regeneration of injured nerve fibers in spinal cord by up-regulating the expression of GAP-43 and NF.

Objective To investigate whether recombinant human endostatin can create a time window of vascular normalization prior to vascular pruning to alleviate hypoxia in Lewis lung carcinoma in mice. Methods Kinetic changes in morphology of tumor vasculature in response to recombinant human endostatin were detected under a confocal microscope with immunofluorescent staining in Lewis lung carcinomas in mice. The hypoxic cell fraction of different time was assessed with immunohistochemical staining . Effects on tumor growth were monitored as indicated in the growth curve of tumors . Results Compared with the control group vascularity of the tumors was reduced over time by recombinant human endostatin treatment and significantly regressed for 9 days. During the treatment, pericyte coverage increased at day 3, increased markedly at day 5, and fell again at day 7. The vascular basement membrane was thin and closely associated with endothelial cells after recombinant human endostatin treatment, but appeared thickened, loosely associated with endothelial cells in control tumors. The decrease in hypoxic cell fraction at day 5 after treatment was also found. Tumor growth was not accelerated 5 days after recombinant human endostatin treatment. Conclusions Recombinant human endostatin can normalize tumor vasculature within day 3 to 7, leading to improved tumor oxygenation. The results provide important experimental basis for combining recombinant human endostatin with radiation therapy in human tumors.

Ethnic medicine industry is facing many problems such as narrow market, exhaustion of resource, decline of ethnic medicine and no qualified successors. Sustainable development theory was utilized to analyse the elements and problems of ethnic medicine industry, and the counter measures were put forward to get rid of the predicament and to realize the sustainable development which depends on the ethnic medicine resources, national medicine, industrial policy, personnel training and modern technology. The development issues of ethnic medicine industry can be solved by the coordination of enterprise, government and public. Finally the ethnic medicine can provide better services for society.
