BACKGROUND:Repair of large-area burns and severe post-traumatic skin defects has always been urgent clinical breakthrough technology bottleneck. With the development of tissue engineering, epidermal stem cel s are increasingly being used in tissue engineering, cel replacement therapy and genetic engineering. Therefore, the isolation and identification of epidermal stem cel s is becoming the research focus of concern.
OBJECTIVE:To review the research progress in biological markers of epidermal stem cel s.
METHODS:The Chinese Biomedical Literature database, CNKI database, China Academic Journals Ful-text database, PubMed database and EMbase database were retrieved for articles about specific markers of epidermal stem cel s using the keywords of“epidermal stem cel s, integrin, keratin, P63, CD71, telomerase, ACE, cx43, hoechst”in Chinese and English. Older theoretical perspectives and repetitive research were excluded.
RESULTS AND CONCLUSION:Final y, only 40 articles were included in result analysis. Epidermal stem cel s bring a new source for skin tissue repair. Epidermal stem cel s distribute in the fol icle eminence and basal layer of the epidermis. About 4%cel s in the basal layer, however, are stem cel s. Therefore, it is critical to correctly isolate, culture and identify skin stem cel s. As a reason, specific markers of epidermal stem cel s become a hotspot. Currently, a great progress in the biological markers of epidermal stem cel s has been made, but there is stil no absolute and proven marker for epidermal stem cel s. Most studies are focusing on integrin, keratin, P63, CD71, connexin 43, and telomerase. In addition, hoechst, CD90, CD98, CD200 have been reported recently. Each marker has its own shortcomings, and there are stil many problems that need to be solved.

Multi-target drugs can simultaneously adjust multiple links of the disease network. Despite the higher efficacy and lower toxicity caused by single targets, multi-target drugs become ideal drugs for treating complicated diseases as well the main direction of drug R & D. By virtue of their structural diversity, higher multi-target activity and lower toxicity, natural products become an important source for developing multi-target drugs. Computer-aided drug design (CADD) is a commonly used multi-target drug R&D method, which mainly includes virtual screening and pharmacophore design. In this paper, the authors made a systematical analysis and discussed the prospects and advantages of various methods for multi-target drug R&D with natural products.

Objective To analyze the handling measure in period of ambo-operation and postoperative care of patients with abdominal surgery in advanced age over 80 years. Methods A retrospective analysis of 102 integrity data of patients with abdominal surgery in advanced age over 80 years was done. Results 100 patients recovery and discharged. The incidence of postoperative complications was 55.9% (55/102). Postoperative death was oberserved in two patients. Conclusion In patients over 80 years old,handling measure in period of ambo-operation is very impor-tant. Degeneration of organ function and more comorbidities made operation more dangerous. A well preoperative prep-aration and postoperative care, an intensive treatment of comorbiditius, the prevention of apoplexia and reducing the chance of emergency operation, will make operation more effective.

Purpose To explore the value of ultrasound contrast time-intensity curves in hepatic tumor qualitative diagnosis and evaluation of tumor ablation effect. Materials and Methods Forty-two patients who were clinically diagnosed as hepatic cancer or cirrhosis underwent contrast enhanced ultrasound for the tumor lesions within the liver, dynamic analysis of the lesions were executed with software SonoLiver CAP, the nature of the tumors were determined and the results were compared with those of the enhanced MRI. Ultrasound guided biopsy was followed with radiofrequency ablation treatment, two-dimensional and contrast enhanced ultrasound were executed two weeks after the ablation, and the results were compared with enhanced MRI findings during corresponding period. Results 52 tumor nodules were found with two-dimensional and color Doppler ultrasound, 65 (33 hyperplastic nodules, 32 malignant lesions) with CEUS, 65 (21 hyperplastic nodules, 44 malignant lesions) with ultrasound contrast time-intensity curves, and 61 (20 hyperplastic nodules, 41malignant lesions) with contrast enhanced MRI; pathological examination revealed that 26 of the lesions were benign and 39 were malignant;there was statistically significant difference (χ2=4.561, P<0.05) between the results of ultrasound contrast time-intensity curves and simple contrast enhanced ultrasound for the assessment of the nature of tumor;no statistically significant difference (χ2=0.003, P>0.05) was found between ultrasound contrast time-intensity curves and enhanced MRI for the assessment of the nature of tumor;there was statistically significant difference (χ2=5.298, P<0.05) between ultrasound contrast time-intensity curves and simple contrast enhanced ultrasound for the assessment of whether the tumor was malignant or benign, when taking biopsy results as the reference standard. Conclusion With ultrasound contrast time-intensity curves, dynamical, intuitive, and quantitative evaluation can be obtained for the perfusion differences between the lesion and the surrounding liver parenchyma, which provides more accurate information for qualitative diagnosis of hepatic tumors thus contains great application value in the evaluation of the effects of radiofrequency ablation for hepatic tumors.
