ObjectivesTo identified the strain 1012 from the National Center of Clinical Laboratory of China for microbe inter-laboratory quality assessment in 2010, and study the taxonomic status of strain 1012 and related species in the genus Actinomyces. Methods The bacterial traditional morphological characteristics, commercial API systems, and 16S rRNA gene sequence analysis were applied to identify the problematic culture of strain 1012. The phylogenetic tree based on the remote information of the prokaryotes systems was constructed to study the taxonomic status and evolutionary relationship of the genus Actinomyces and related species in the family Actinomycetaceae. Results Strain 1012 was determined as a kind of facuhative anaerobic,non-spot-forming,Gram-positive coryneformbacteria,which was identifiedto Actinomyces turicensis for the phenotypic biochemical characteristics of more than 60 items, The comparative study of 16S rRNA gene showed the strain 1012 with 99. 8％ similarities to Actinomyces turicensis, but only 90. 6％ to the type species of Actinomyces bovis in the genus Actinomyces. However, the comparative study of 16S rRNA gene showed the strain 1012 with only 90. 6％ homology to the type species of Actinomyces bovis in the genus Actinomyces. Further phylogenetic analysis showed that nine independent clusters were grouped in the family Actinomycetaceae, of which four clusters were separately represented the genera Varibaculum,Mobiluncus, Actinobaculum and Arcanobacterium, while other five clusters all were designated to the genus Actinomyces. The study showed strain 1012 was located in genus Ⅲ of Actinomyces, yet with a relatively long genetic distance to Actinomyces bovis. ConclusionThe genus Actinomyces may be reclassified as one genus Actinomyces sensu stricto and several new genera for the genotypic characteristics.

OBJECTIVETo prepare flexible proanthocyanidins nanoliposomes, and explore the in vitro release behavior of proanthocyanidins flexible nanoliposomes and general nanoliposomes.

METHODFlexible proanthoeyanidins nanoliposomes were prepared proanthocyanidins using a film dispersion method, characterized by transmission electron microscope, and the in vitro release action was studied in different dissolution mediums using dynamic dialyse method with the content of total phenol as index.

RESULTThe in vitro release of both proanthocyanidins flexible nanoliposomes and general nanoliposomes were in accordance with Weibull distribution.

CONCLUSIONProanthocyanidins flexible nanoliposomes without pressure had similar in vitro release behavior with general nanoliposomes.

Objective To investigate the changes of antimicrobial peptide LL-37 and C-reactive protein (CRP ) in the patients with Pseudomonas aeruginosa positive sputum culture and their mutual relation . Methods Fifty cases of Pseudomonas aeruginosa positive sputum culture and 27 cases undergoing physical ex-amination in the Guangdong Provincial Hospital of Chinese Medicine from September 2016 to May 2017 were selected as the research subjects .The level of antimicrobial peptide LL-37 was detected by double antibody sandwich ELISA and the CRP level was detected by immunoturbidimetry .Results The levels of antimicrobial peptide LL-37 and CRP in the Pseudomonas aeruginosa positive sputum culture group were significantly high-er than those in the healthy control group ,the difference was statistically significant (P< 0 .05) ,and they showed the positive correlation (r=0 .411 ,P<0 .05) .Conclusion In positive sputum culture of Pseudomonas aeruginosa ,antimicrobial peptide LL-37 and CRP levels are increased ,which has a certain clinical application value for the early diagnosis of infection .

Objective To explore the expression of Livin and Beclin1 in epithelial ovarian cancer and their relations with tumor invasion and metastasis. Methods A total of 65 patients with epithelial ovarian cancer who were admitted and treated in our hospital and Jilin University Affiliated Hospital, plus 15 blocks of normal ovarian tissue samples were selected. Excised ovarian tissues were tested via immunohistochemistry to test the protein expression of Livin and Beclin1, and their relations with tissue differentiation of ovarian cancer, lymphatic metastasis and clinical staging were analyzed. Results Positive rate of expression of Livin, rare expression in normal ovarian tissues (6.7%), and the highest expression rate in tissues of ovarian cancer (68.6%);Positive rate of expression of Beclin1,the highest expression rate in normal ovarian tissues (93.3%) and the lowest in tissues of ovarian cancer (37.1%). Tissue differentiation of ovarian cancer, lymphatic metastasis and clinical staging were interrelated with the expression degree of Livin and Beclin1 (P<0.05). Conclusion Expression of Livin and Beclin1 in epithelial ovarian cancer and tumor invasion and metastasis plays an important role and may become a new target in the treatment of ovarian cancer.

Objective To analyze the senile lying-in woman whose psychological characteristics and the effect of psychological nursing intervention. Methods Senile women prenatal and childbirth in our hospital were selected as the research objects, who were respectively given routine nursing and corresponding psychological nursing intervention,the differences of the second labor,delivery methods,perinatal negative emotion score of senile lying-in women of two groups,and so on were compared. Results The second labor time (34.82±14.31)min of senile lying-in women of observation group, oxytocin utilization rate (6.25%), prenatal negative emotions scores of HAMD (15.14±1.35),HAMA(13.34±1.11),postpartum negative emotions scores HAMD(12.53±1.64),HAMA(11.41±1.09) were all obviously lower than those of control group.The rate of vaginal delivery (79.69%) was significantly higher than that of control group(P<0.05). Conclusion Pertinent psychological nursing can effectively shorten the labor time of women and raise the rate of vaginal delivery,effectively relieve the perinatal negative emotion.
