Objective To compare the efficacy of endovenous laser treatment combined with transilluminated powered phlebectomy and traditional surgical treatment for great saphenous varicosity. Methods From January 2014 to January 2015,77 patients diagnosed as great saphenous varicosity were enrolled. They were randomly divided into two groups, 37 patients received endovenous laser treatment combined with transilluminated powered phlebectomy and the other 40 patients underwent traditional surgical treatment. The related indicators were compared.Results The mean operation time,average bleeding volume,operative incisionquantity and average hospitalization time of EVLT+ TIPP group were (66.1±14.7) min,(24.4±10.5) ml,5.7±1.7,(5.6±1.4) d respectively,of control group were (84.3±18.5) min,(59.0±15.6) ml,8.0±1.8,(10.1±3.1) d respectively,there were significant differences between the two groups(t =-4.749,-11.460,-5.714;P<0.001) .There were no significant complications in the two groups.In the EVLT+ TIPP group,6 patientsoccurred patsubcutaneous induration, 5 patients occurred subcutaneous hematoma and 7 patients had skinparesthesias.In the traditional operation group,2 cases occurred patsubcutaneous induration,3 cases occurredsubcutaneous hematoma and 2 cases had skin paresthesias.The EVLT+ TIPP group was slightly higher than thetraditional operation group in the complications, but there were no significant differences between them ( P>0.05).During a mean follow?up time of (18±7) months(12 months to 24 months),1 patient recurrence in theEVLT+ TIPP group,2 cases recurrence in the traditional operation group.The recurrence rates of the two groupswere similar,the difference was not significant between them(P=1.000) .Conclusion Endovenous lasertreatment combined with transilluminated powered phlebectomy for great saphenous varicosity is effective andsafe.It also has the advanta and better cosmetic results.

Objective To investigate the expression of specific marker molecules in hair-inducing activity of long-term cultured human dermal papilla cells (HDPCs) in vitro.Methods After dissected and cultured the HDPCs in vitro,the cells of passages 1 to 8 were used for experiments.The growth appearances of HDPCs in different passages were observed under inverted microscope.To detect the expression of specific marker molecules of long-term cultured HDPCs,the alkaline phosphatase (ALP) activity of the HDPCs was examined,and the specific genes ALP and insulin-like growth factor-1 (IGF-1) expression levels of HDPCs were determined by real-time quantitative PCR.Results After long-term cultured in vitro,the ALP and IGF-1 expression levels of HDPCs gradually decreased in different passages,as well as the display of the aggregated and cartouche growth.The ALP and IGF-1 expression levels of HDPCs in passage 1 was the highest,they were almost about 6.8-fold and 3.5-fold higher than the HDPCs in passage 8.The ALP staining of the HDPCs in passage 1 and passage 2 were evident,but the cells' ALP staining gradually became much weaker than the cells in the previous passages after the long-term cultured in vitro.Conclusions The expression levels of specific marker molecules ALP and IGF-1 of the HDPCs decrease gradually after long-term cultured in vitro,and the higher passage HDPCs lost the special aggregated and cartouche growth appearance,and hence lead to the loss of hair-inducing activity of HDPCs.

BACKGROUND:Fol owing physicochemical treatment and high-temperature calcinations, heterogeneous
biological bone becomes a ceramic-like heterologous bone forming a similar structure to the human bone that is a natural network pore structure, which is conducive to seed cel adhesion and proliferation.
OBJECTIVE:To observe the feasibility of constructing tissue-engineered bone through combination of sintered bone and bone marrow mesenchymal stem cel s to repair alveolar defects.
METHODS:Sheep bone marrow mesenchymal stem cel s as seed cel s were combined with the high
temperature sintered bone as scaffold materials to construct tissue-engineered bone. Under general anesthesia, sheep bilateral mandibular first premolars were removed in batches, the alveolar ridge space between the distal root and mesial root of the second premolar to form a bone defect area of 5 mm×5 mm×5 mm. Twelve
experimental sheep were equal y randomized into tissue-engineered bone group and sintered bone group, which were implanted with tissue-engineered bone and sintered bone, respectively, at the left surgical area of the
mandible. The right surgical area was considered as blank control group.
RESULTS AND CONCLUSION:After high-temperature calcinations, the sintered bone was chalk in color, exhibiting a porous structure as the natural cancel ous bone. The porosity was (66.10±1.32)%, and the pore size was between 137.44μm and 538.72μm. After 24 hours of bone marrow mesenchymal stem cel s inoculated to the sintered bone, a large number of cel s are visible adherent to the scaffold;up to day 7, extracel ular matrix was secreted and there was no clear boundary between the cel s and the matrix. X-ray films showed that the tissue-engineered bone and pure sintered bone implants were embedded in the surgical area, and there was a low-density shadow at the edge of the sintered bone. Hematoxylin-eosin staining showed bone trabecular formation at the experimental side, but no obvious bone formation at the control ed side. Tissue-engineered bone prepared by bone marrow mesenchymal stem cel s and sintered bone can better repair sheep alveolar bone defects, which is an ideal seed cel and scaffold material for smal range bone defects.
