ABSTRACT
Objective To investigate human papillomavirus (HPV) genotypes in adult patients with plantar warts,and to explore their relationship with clinical features of adult plantar warts.Methods PCR,gene sequencing and TA-cloning technique were performed to detect HPV types in 221 patients with plantar warts.Meanwhile,clinical data were recorded,including patients' age,disease duration,symptoms and number of warts.Results Of 221 specimens,HPV DNA was detected in 215,with the HPV-positive rate being 97％.Single HPV infections were detected in 206 specimens (96％,206/215),among which,HPV types included HPV-27 (44.7％,92/206),-2 (12.1％,25/206),-57 (7.3％,15/206),-7 (Alpha genus;0.5％,1/206),-65 (Gamma genus;0.5％,1/206),-1 (33.5％,69/206) and-63 (Mu genus;1.5％,3/206).There were no significant differences in age,disease duration,number of warts,incidence of pain and gender among patients with HPV-27,-2 or-57 infections.Compared with patients with HPV-27 infection,patients with HPV-1 infection were more related to age ≤ 30 years,disease duration ≤ 1 year,number of warts ≤ 2 and high incidence of pain.Conclusion HPV-27,-2,-57 and-1 are the main types in adult patients with plantar warts,and HPV types are correlated with clinical features of adult plantar warts.

ABSTRACT
Exercise fatigue is a physiological phenomenon not only for athletes, but also for astronauts. It is vital for athletes with hard training and astronauts with the heavy exercises for the mission in manned space flight to know how to solve the exercise fatigue. This article reviewed current commonly used TCM protective measures against fatigue.
ABSTRACT
To investigate the relationship between the plasma biomarker proteins and the states of Zang-Fu organs in patients with phlegm or blood stagnation syndromes due to hyperlipidemia and atherosclerosis.
ABSTRACT
With the rapid development of modern science and technology,the post-genomics period has come with the complement of the sequence of body genome including several tens of human genome,the emphasis of life science transfer from instruction genome to the post-genomics period,functional genome.Proteomics is the most important part of it.The technology of proteomics is advanced day by day.Except the classical two dimensional gel electrophoresis,the technology of multi-dimensional liquid chromatography and the technology of isotope coded-affinity tags have been successively developed,as well as protein chip and phage display have been applied extensively.This article simply summarizes the key technologies of proteomics.
ABSTRACT
Objective: To study the relationship between human herpes vi rus 6 (HHV-6) infection and oral squamors cell carcinoma. Methods: The serum anti-HHV-6 antibody titers from 16 cases of oral squamors cell carcinoma (OSCC) and 16 control subjects were detected by indirect immunofluores cence assay. HHV-6 DNA in peripheral blood mononuclear cells was amplified by P CR and the specificity was confirmed by Southern-blot hybridization with an int ernal probe oligonuclotide. An immunohistochemical staining was used to detect H HV-6 antigen in OSCC tissues. Results: Positive expression of s erum HHV-6 IgG antibody was found in all the cases of OSCC and in 12 of the 16 controls. Geometric mean titer of OSCC group and control group was 1∶118 and 1 ∶64 respectively (P
