Objective To study cervical HPV infection in female patients with vulvar condyloma acuminatum(CA)from Shanghai area.MethodsExfoliated cells were obtained from cervices and vulva lesions of CA of 194 patients.respectively.HPV genotyping was carried out in cell samples using capture-hybridization method and gene chip techniques.Results HPV was detected in vulva lesions of all the 194 patients.Among them,74.2%(144/194)were positive for low risk(LR)-HPV,and 25.8%(50/194)for high risk(HR)-HPV.A single HPV genotype(6 or 11)was detected in 136(94.4%)patients with LR-HPV.and mixed genotypes of LR-HPV and HR-HPV in 46(86%)patients with HR.HPV.Of the 194 patients.85.6%(166/194)were complicated by cervical HPV infection.including 119(61.4%)cases of LR-HPV and 46(23.7%)cases of HR-HPV,In the case of HPV genotype.the consistence between CA lesions and cervix was 95.8%(159/166).The prevalence of LR-HPV declined sequentially from subtype 11 to 6 and 53,and that of HR-HPV from subtype 16 to 18 followed by 52,31,45 and 58.Conclusions There is a high rate of infection with HR-HPV in female patients with CA.and nearly one quarter of these patients are complicated by cervical HR-HPV infection.

Objective To retrospectively assess the clinical manifestations and treatment of secondary syphilis with ocular impairment as the initial symptom. Methods Clinical data were retrospectively analyzed on secondary syphilis with ocular impairment as the initial symptom collected from September 1998 to October 2008. Results There were 11 syphilitic patients presenting acute ocular impairment as their initial manifestation. Skin eruptions developed simultaneously with ocular impairment in 2 patients, following ocular impairment in 9 patients. All patients were positive for rapid plasma reagent test (RPR) and treponema pallidum haemagglutination assay (TPHA), but negative for HIV. Of these patients, 9 suffered from uveitis (iridocyclitis, choroiditis or panuveitis), 2 from optic neuritis; 3 had unilateral ocular involvement, 8 had bilateral ocular involvement. After treatment with injected penicillin or ceftriaxone sodium, 9 patients experienced complete visual recovery, 2 partial visual recovery. Conclusions Ocular impairment occurs in patients with secondary syphilis at a low incidence, with no characteristic clinical manifestations. For patients who have no response to conventional ocular therapy, ocular syphilis should be considered and serological examination for syphilis is recommended.

is famous for its important therapeutic effects. Saponins are bioactive compounds found in different parts and developmental stages of plants. Thus, it is urgently to study saponins distribution in different parts and growth ages of plants. In this study, potential biomarkers were found, and their chemical characteristic differences were revealed through metabolomic analysis. High-performance liquid chromatography data indicated the higher content of saponins (, Rg1, Re, Rd, and Rb1) in the underground parts than that in the aerial parts. 20()-Protopanaxadiol saponins were mainly distributed in the aerial parts. Additionally, the total saponin content in the 3-year-old plant (188.0 mg/g) was 1.4-fold higher than that in 2-year-old plant (130.5 mg/g). The transcriptomic analysis indicated the tissue-specific transcription expression of genes, namely, , , , , and , which encoded critical synthases in saponin biosyntheses. These genes showed similar expression patterns among the parts of plants. The expression levels of these genes in the flowers and leaves were 5.2fold higher than that in the roots and fibrils. These results suggested that saponins might be actively synthesized in the aerial parts and transformed to the underground parts. This study provides insights into the chemical and genetic characteristics of to facilitate the synthesis of its secondary metabolites and a scientific basis for appropriate collection and rational use of this plant.

The cultivation of plants is hindered by replanting problems, which may be caused by plant-driven changes in the soil microbial community. Inoculation with microbial antagonists may efficiently alleviate replanting issues. Through high-throughput sequencing, this study revealed that bacterial diversity decreased, whereas fungal diversity increased, in the rhizosphere soils of adult ginseng plants at the root growth stage under different ages. Few microbial community, such as , Cytophagaceae, , , Sphingomonadaceae, and Zygomycota, were observed; the relative abundance of microorganisms, namely, , Enterobacteriaceae, , Cantharellales, , , and Chytridiomycota, increased in the soils of adult ginseng plants compared with those in the soils of 2-year-old seedlings. 50-1, a microbial antagonist against the pathogenic , was isolated through a dual culture technique. These bacteria acted with a biocontrol efficacy of 67.8%. The ginseng death rate and abundance decreased by 63.3% and 46.1%, respectively, after inoculation with 50-1. Data revealed that microecological degradation could result from ginseng-driven changes in rhizospheric microbial communities; these changes are associated with the different ages and developmental stages of ginseng plants. Biocontrol using microbial antagonists alleviated the replanting problem.
