产后阴道菌群分布情况及乳杆菌活菌胶囊治疗的疗效

目的探讨产后阴道菌群分布情况及乳杆菌活菌胶囊治疗的疗效。方法选择200例在桐乡市妇幼保健院分娩的产妇,在分娩前与分娩后6周检测产妇的阴道pH,并对阴道分泌物进行细菌培养。比较分娩前后产妇的阴道pH值、乳酸杆菌检出率。根据患者意愿将未患有阴道炎的产妇分为观察组与对照组,观察组予以乳杆菌活菌胶囊治疗,每天1次,每次1粒,连用10d,对照组不采取任何治疗,分别在分娩后3个月、6个月检测产妇的阴道pH,并对阴道分泌物进行细菌培养,比较两组阴道pH值及乳酸杆菌检出率的变化情况及细菌性与念珠菌性阴道炎的发病率,探讨乳杆菌活菌胶囊的疗效。结果分娩后6周产妇的阴道pH明显高于分娩前(P0.05),而阴道乳酸杆菌检出率却低于分娩前(χ2=73.87,P0.01);产妇产后6周阴道炎患病率为11.0%,分娩后3个月与分娩后6个月,两组产妇阴道pH均较治疗前下降(P0.05或P0.01),且观察组的下降幅度大于对照组(P0.05),而两组产妇阴道乳酸杆菌检出率却较治疗前增多(χ~2=20.15、36.27,3.88、6.30,P0.05或P0.01),且观察组的增多幅度大于对照组(χ~2=3.98、8.66,P0.05或P0.01);分娩6个月后观察组细菌性与真菌性阴道炎发病率低于对照组(χ~2=24.79,P0.01)。结论产妇产后会出现阴道菌群紊乱,阴道pH上升,乳酸杆菌检出率下降,阴道炎患病率上升,采用乳杆菌活菌胶囊干预治疗能有效的平衡阴道菌群,减少产妇产后阴道炎的发生,是一种安全有效的治疗方法。

Recent advances in the study of Kaposi's sarcoma-associated herpesvirus replication and pathogenesis

It has now been over twenty years since a novel herpesviral genome was identified in Kaposi's sarcoma biopsies. Since then, the cumulative research effort by molecular biologists, virologists, clinicians, and epidemiologists alike has led to the extensive characterization of this tumor virus, Kaposi's sarcoma-associated herpesvirus(KSHV; also known as human herpesvirus 8(HHV-8)), and its associated diseases. Here we review the current knowledge of KSHV biology and pathogenesis, with a particular emphasis on new and exciting advances in the field of epigenetics. We also discuss the development and practicality of various cell culture and animal model systems to study KSHV replication and pathogenesis.     

A Unique Protease Cleavage Site Predicted in the Spike Protein of the Novel Pneumonia Coronavirus (2019-nCoV) Potentially Related to Viral Transmissibility

Curcuminoids as inhibitors of thioredoxin reductase: A receptor based pharmacophore study with distance mapping of the active site

Curcumin is the yellow pigment of turmeric that interacts irreversibly forming an adduct with thioredoxin reductase (TrxR), an enzyme responsible for redox control of cell and defence against oxidative stress. Docking at both the active sites of TrxR was performed to compare the potency of three naturally occurring curcuminoids, namely curcumin, demethoxy curcumin and bis-demethoxy curcumin. Results show that active sites of TrxR occur at the junction of E and F chains. Volume and area of both cavities is predicted. It has been concluded by distance mapping of the most active conformations that Se atom of catalytic residue SeCYS498, is at a distance of 3.56 from C13 of demethoxy curcumin at the E chain active site, whereas C13 carbon atom forms adduct with Se atom of SeCys 498. We report that at least one methoxy group in curcuminoids is necessary for interation with catalytic residues of thioredoxin. Pharmacophore of both active sites of the TrxR receptor for curcumin and demethoxy curcumin molecules has been drawn and proposed for design and synthesis of most probable potent antiproliferative synthetic drugs.     

The structure, reproduction and taxonomy of Vidalia and Osmundaria (Rhodophyta, Rhodomelaceae)

Comprises species occurring mostly in subtidal habitats in tropical, subtropical and warm-temperate areas of the world. An analysis of the type species, V. spiralis (Sonder) Lamouroux ex J. Agardh, a species from Australia, establishes basic characters for distinguishing species in the genus. These characters are (1) branching patterns of thalli, (2) flat blades that may be spiralled on their axis, (3) width of the blade, (4) primary or secondary derivation of sterile and fertile branchlets and (5) position of sterile and fertile branchlets on the thalli. Application of the latter two characters provides an important basic method for separation of species into three major groups. Osmundaria , a genus known only in southern Australia, was studied in relation to Vidalia , and its separation from the Vidalia assemblage is not accepted. Species of Vidalia therefore are transferred to the older genus name, Osmundaria. Two new species, Osmundaria papenfussii and Osmundaria oliveae are described from Natal. Confusion in the usage of the epithet, Vidalia fimbriala Brown ex Turner has been clarified, and Vidalia gregaria Falkenberg, described as an epiphyte on Osmundaria pro/ifera Lamouroux, is revealed to be young branches of the host, Osmundaria prolifera.     

New or rare chromosome counts in Artemisia L. (Asteraceae, Anthemideae) and related genera from Kazakhstan

Fifteen chromosome counts of six Artemisia taxa and one species of each of the genera Brachanthemum, Hippolytia, Kaschgaria, Lepidolopsis and Turaniphytum are reported from Kazakhstan. Three of them are new reports, two are not consistent with previous counts and the remainder are confirmations of very scarce (one to four) earlier records. All the populations studied have the same basic chromosome number, x = 9, with ploidy levels ranging from 2x to 6x. Some correlations between ploidy level, morphological characters and distribution are noted.
