宫颈癌与HPV感染

宫颈癌是最常见的恶性肿瘤之一,全球发病率最高的是南非,其次在亚洲.据统计,世界上每年的新发病例约46万,每年约有25万人死于宫颈癌.在我国,每年宫颈癌的新发病例数超过13万,每年死于宫颈癌的妇女约有2万人.随着研究的深入,宫颈癌与人类乳头瘤样病毒(HPV)关系越来越被基础研究者和临床医生所重视,本文就HPV感染的相关性及目前较新的治疗方法作一综述.     

Fungal keratitis infected eye treatment with antibiotic-loaded zinc ions tagged polyvinyl acetate phthalate-g-polypyrrole drug carrier

Currently, the treatment of fungal keratitis (FK) infection remains a major clinical challenge, and current investigations, development in the field have widened approaches. The present work was aimed to synthesis a dual role novel carrier system consisting of Ofloxacin (OFL) and Nepafenac (NF) hydrophobic drugs incorporated in Zinc ions (Zn²⁺) tagged Polyvinyl acetate phthalate (PVAP) grafted Polypyrrole (PPy) carrier (OFL&NF-Zn²⁺/PVAP-g-PPy) to treat FK infection. The FT-IR, SEM, and dynamic light scattering revealed the carrier chemical structure, spherical shape, and the average particle size of 691.3 ± 1 nm. The carrier’s entrapment of OFL and NF drugs has been observed at 78.23% and 60.03%. The carrier exhibited significant antifungal activity at the concentration of 58 mg mL⁻¹ against Candida albicans which was lower than that of the free ofloxacin. The cell viability results suggested up to 70 μg/mL concentration of OFL&NF-Zn²⁺/PVAP-g-PPy did not induce any cytotoxicity on cultured ADSC cells at 48 h treatment time. It confirms the fact that the OFL&NF-Zn²⁺/PVAP-g-PPy carrier showed good biocompatibility and good anti-fungal activity. Thus the carriers provide a significant potential to improve the bioavailability of topically applied drugs to treat fungal eye infection.     

玉林市和贵港市城区近郊水体孑孓索科线虫感染情况的研究

目的：弄清玉林市和贵港市库蚊线虫的资源情况,为保护和利用索科线虫资源提供理论依据.调查方法：根据库蚊孑孓的生活习性,选取不同的生态环境,在玉林市和贵港市城区近郊随机选取有水的稻田及水沟等水体,随机多点取水以获取孑孓,并带回饲养,记录收集到的孑孓的总数,观察孑孓体内线虫脱出的情况,计算出孑孓索科线虫的感染率.结果：玉林和贵港均有线虫资源,且以玉林的绿杨村最为丰富.感染强度为2.0%、100%、100%、3.03%、0.78%;感染强度最高可达到1.3/条.

分析了福建省的莆田、厦门两市１８２例原发性肝癌（ＰＨＣ）病案的临床特点，探讨与ＨＢＶ感染、ＨＢ之间关系，以及观察其中部分病例。采集其血清作ＨＢＶ标志物检测，ＰＨＣ患者１２９例ＨＢｓＡｇ阳性７７例，阳性率５９．６９％（Ｒ－ＰＨＡ），比当地自然人群调经４．２９％高出１２．９１倍，６１例ＰＨＣ血清作ＨＢＶ标志物检查（ＥＩＡ），有９１．８０％病例感染ＨＢＶ，比配对对照组感染率８．２０％高出１０．２０倍（Ｐ     

Sorting out the value of spectroscopic tools to assess the Colletotrichum acutatum impact in olive cultivars with different susceptibilities

The olive tree (Olea europaea L.) can be affected by Colletotrichum acutatum, causing a loss of yield and quality of the final products, whilst the incidence of this fungal infection depends on several factors, including cultivar susceptibility. Thus, the effect of C. acutatum infection in cultivars displaying different susceptibilities to this fungal disease (‘Galega Vulgar’ ‐ susceptible, ‘Cobrançosa’ ‐ moderately susceptible, ‘Picual’ ‐ tolerant) has been assessed through spectrophotometric methods and HPLC, while the FTIR spectra of the cuticles have been concomitantly registered, resorting to the ATR accessory. With the support of multivariate analysis, these spectra allowed to discriminate olives with distinct infection times, besides retrieving evidences concerning the different susceptibility of each cultivar, while these observations were reinforced by the spectrophotometric and chromatographic methods. Furthermore, the assessment of the phenolic profile evidenced individual compounds in the distinct cultivars, so as their variations in response to the fungal infection.
