Research has determined that undetectable iral leels - - although not a cure - - slows iral replication to the point where the irus has less chance of mutating and deeloping resistance to the drugs 研究证实体内病毒保持在检测不出的水平尽管并不意味着痊愈,但可以将病毒的复制降低到使其不易变异和产生抗药性的程度。
Interestingly , cultured hepatocytes responded to iral replication by displaying signs of distress and cell death and by expressing interferon - beta , a cellular antiiral , in an effort to control the infection 有趣的是,培养系统同时也通过应激或细胞凋亡来对抗病毒复制,并且表达干扰素,产生细胞毒性,控制炎症进展。
Children who catch lower respiratory iral infections , such as the common cold , during their first year of life and are also prone to allergies are at greater risk of deeloping asthma , according to new research 据最新研究表明,孩子在出生后1年内得下呼吸病毒道感染,如普通的伤风,并易于过敏者,患哮喘的几率也大大增加。
The herpesiruses bring untold suffering , but may not be all bad . chronic latent infection with specific iral strains protects mice against some bacterial infections , a nature study reeals this week1 疱疹病毒带来的痛苦自不必说,但是也不是一无是处。本周的《自然》上说,某些病毒株的持续潜在感染能保护小鼠免受一些细菌的感染。
Conclusion : for hcc patients with hb chronic infection / exposure , a high iral load prior to treatment is an aderse factor for surial and may be associated with a higher incidence of seere hepatitis during chemotherapy 结论:有慢性乙肝感染或接触史的肝细胞性肝癌患者,化疗之前有高病毒负荷量是其生存的负面因素,并与化疗期间急性肝炎的高发生率相关
Since pneumonia is associated with inflammatory features in the sputum but no gram ' s staining of microorganisms , the differential diagnosis should focus on a iral , chlamydial , or mycoplasmal infection , although this patient ' s prior exposure to antibiotics may reduce the likelihood of finding another pathogen on gram ' s staining 既然肺炎病人的痰液应伴随炎症特征,而该患者的痰液革兰氏染色检查未见微生物,故鉴别诊断应该集中在病毒、衣原体或支原体感染,虽然患者先前的抗生素治疗可能会降低革兰氏染色检查中其他病原体的发现率。
