Objective To observe the damage to Langerhans cells induced by UVB irradiation,and to evaluate photoprotective effect of these cells from UVB irradiation by epigallocatechin-3-gallate (EGCG).Methods Biopsy specimens were obtained from normal adult foreskin,and epidermal cells were isolated.Density gradient centrifugation and magnetic cell sorting were used simultaneously to purify Langerhans cells from the cell suspension.These cells were then divided into three groups,control (no ir- radiation or EGCG treatment),UVB (irradiation) and EGCG (irradiation+ECCG treatment) groups. The cells in the UVB and EGCG group were irradiated by UVB (30 mJ/cm~2).After the irradiation,the U- VB group was incubated with RPMI-1640 containing 10% bovine serum for 4 hours,while the EGCG group with the same medium containing 200?g/mL of EGCG for 4 hours.Another four hours after the treatment, the cells were collected for the detection of apoptosis rate by propidium iodide staining and flow cytometry. Results Exposure to UVB (30 mJ/cm~2) significantly increased the apoptotic rate of Langerhans cells.The apoptotic rate in EGCG group was significantly lower than that in the UVB group,but was higher than that in the control group.Conclusion Rate of apoptosis of Langerhans cells could be increased by UVB irradia- tion,while EGCG could prevent the increase of apoptosis.

Objective To explore the clinical value of applying digital technology to make the course of toe vein clear before toe free flap transplantation for thumb reconstruction.Methods Before operation,scan the donor and recipient site by CT,and apply digital three-dimensional CT angiography reconstruction technology to got threedimensional images of the arteries and veins in the donor site for 22 various defected thumbs which were going to have toe free flap transplantation operation,thus indentifyed the types of FDMA and the distribution and course of the toe vein from June,2012 to March,2013.Used computer assisted anatomical modeling to analyze three-dimensional images of blood supply of the donor site and degree of defect of the recipient site and guide the operative design in the donor site according to the digital three-dimensional reconstruction technology.Conducted toe free flap transplantation for thumb reconstruction in accordance with the design.Results It shows that 64-slice dual-source spiral CT could well display the size,distribution and course of toe vein.The toe veins were clarified to two groups,deep one and superficial one whose diameter was larger and was the main reflux vein of the toe.Dorsal vein of the toe origind from venous plexus in the nail bed and it travels along the back of the toe to reach to the near side of metatarsophalangeal joint.And then it beeomes three to four dorsal metatarsal veins to infused dorsal venous arch of foot.The rule of its course was:centralize-decentralize-connect-decentralize again.The great saphenous vein origins from the inner side of dorsal venous arch of foot,rises along the crus before malleolus medialis and collect three larger tributaries:medial malleolar branches-anterior crural branch-outside crural branch.The small saphenous vein derives from the outside of dorsal venous arch of foot and winds behind lateral malleolus up to the back of the curs and infuses to the vein.Conclusion It is useful for venous return,reducing the incidence of vascular crisis by applying toe flap to reconstruct thumbs and clarifying the course and distribution of toe vein with the aid of digital three-dimensional technology to design operation,thus improving the survival rate of toe flap transplantation.

Based on thermodynamic principle, the critical relative humidity of electrolytes is closely related to their solubility. The authors explored the relationship theoretically and calculated critical relative humidity of 21 electrolytes from their solubility in the light of Raoult's law and extended Wilson model. The results indicate that the critical relative humidity values calculated by Raoult's law can not accord with the reported ones and there is a systematic error in the high concentration range; while these calculated by extended Wilson model are comparable to the reported ones.

BACKGROUND: Extensive liver resection or liver transplantation operated on patients with combined hepatic cirrhosis and other complications correlates with high morbidity and mortality.Child-Turcotte-Pugh scoring system is now widely used in the assessment of liver function.This classification scheme includes three clinical indicators and two biochemical indices;however,it seems difficulty on directly evaluating functional status of hepatocytes.OBJECTIVE: To explore the practicability of bioluminescence adenosine triphosphate (ATP) determination assay to assess the functional reserve of residual hepatocytes,DESIGN,TIME AND SETTING: Case contrast study,which was carried out in the Second Affiliated Hospital,Sun Yat-sen University from January 2005 to March 2006.PARTICIPANTS: Thirty-two patients who underwent major extra-and intra hepatic surgery including liver transplantation were randomly divided into three groups based on hepatic cirrhosis grading standard,including normal group (n=7),macronodular cirrhosis group (n=9),and micronodular cirrhosis group (n=16).METHODS: Routine examination and biochemical indexes of liver were performed preoperatively,including glutamic oxalacetic transaminase (GOT) and total bilirubin (TBIL).Liver specimens were delivered by aseptic technique during operation and enzymatic digested.Cell suspension was cultured and centrifuged.Hepatocytes were counted and dispensed cell suspension to be used for ATP extraction and measurement.MAIN OUTCOME MEASURES: ATP content,preoperative biochemical parameters of liver function,and correlation between biochemical parameters and ATP content.RESULTS: The ATP content in the macronodular cirrhosis group was significantly higher than that in the micronodular cirrhosis group and normal group (P=0.000 1,0.004).While,the ATP content in the micronodular cirrhosis group was also significantly higher than that in the normal group (P=0.004).ATP content (mole/cell) wassignificantly positively correlated with serum glutamic oxalacetic transarninase (r=-0.609 3,P=0.000 2) and TBIL (r=0.614 5,P=0.000 2).CONCLUSION: ATP assay can directly evaluate functional reserve of liver parenchyma and reflect high operative risk status (HORS) and course of postoperative recovery in major hepatic resection.

In this study, the human umbilical vein endothelial cell model was used to study the regulating effect of lipophilic components in Salvia miltiorrhiza on angiogenesis, and explore its possible mechanism. The cell model was established to determine the effect of lipophilic components in S. miltiorrhiza on the proliferative activity and migration capacity of endothelial cells. Then the realtime fluorescence quantification PCR technology was applied to detect the changes in the gene expressions of angiogenesis-related cytokines VEGF-A, VEGF-C and MMP-9. The results showed that 5 mg x L(-1) lipophilic components in S. miltiorrhiza could inhibit the proliferation and migration of endothelial cells, and reduce the expression of VEGF-A and MMP-9 genes. It indicated that lipophilic components in S. miltiorrhiza may inhibit the proliferation and migration of endothelial cells by inhibiting the expression of VEGF-A and MMP-9 genes, so as to show the inhibitory effect on angiogenesis.
