OBJECTIVETo promote development and utilization of Ophiocordyceps gracilis in xinjiang and provide basic data for researching and sustainable developing medicine fungus related to O. gracilis.

METHODA white strain SFYT002 isolated from the sclerotium of O. gracilis in Xinjiang was researched by morphological observation, ITS and 18SrDNA sequencing. The ITS and 18SrDNA sequences of the strain were determined, BLAST was compared with the other sequences of Tolypocladium in GenBank. The phylogenetic trees of ITS and 18SrDNA sequences were analyzed in Tolypocladium. In addition, the filter paper method was used to study the antibacterial effects.

RESULTThe main morphological characters of this strain were white cotton-like colonies, phialide with inflated base, drastically sharping with partially bending tips, small and transparent budding spores with being always assemble to spearhead and globular, subglobular or ellipse conidiospores. The phylogenetic trees of ITS and 18SrDNA sequences were constructed and analyzed in Tolypocladium. It was resulted that Tolypocladium was confirmed to be monophyletic, and the strain SFYT002 was the same as the systematic position of others of T. inflatum. Meanwhile, the antibacterial test was performed against the 4 common pathogenic bacteria. It was showed that both fermentation and its extracts of different polar from this strain possessed good anti-bacteria capacities.

CONCLUSIONThe strain SFYT02 was identified as T. inflatum, and inhibited effectively growth of bacteria.

Objective · To investigate the prevalence of passive smoking among pregnant women in Shanghai and to analyze its influencing factors and to provide the basis and suggestion for making related intervention measures to reduce the harm of secondhand smoke on the health of pregnant women. Methods · From July to October 2014, pregnant women and their spouses were recruited for a questionnaire investigation at the antenatal care clinics of 3 maternity hospitals and 3 community hospitals in Shanghai. The questionnaire included demographic information, family basic situation and cognitive status of passive smoking. Results · The passive smoking rate before pregnancy in the 2831 pregnant women, who were involved in the investigation, was 17.1%. The passive rate during pregnancy was 7.8%. The difference between these two rates was statistically significant (P<0.05). 71.0% of the pregnant women have passive smoking for 15~59 min each day. Relative to home and work place, the passive smoking rate of pregnant women in public place was the highest (P<0.05). The passive smoking rate of pregnant women was significantly associated with the educational level of smoking spouses and the attitude of pregnant women when they faced the smokers. Conclusion · The passive smoking rate of pregnant women is influenced by the educational level of their spouses and the pregnant women's feedback to the smokers face to face. Public places are the most important exposure places to secondhand smoke for pregnant women. In order to reduce the harm from passive smoking to pregnant women and their fetuses, the related measures of smoking control at home education and smoking ban in public place should be made.

Myeloid-derived suppressor cells (MDSCs) are a heterogeneous group of immunosuppressive cells derived from bone marrow stem cells.MDSCs can not only strongly inhibit the anti-tumor immune reactions mediated by T cells,but also directly accelerate angiogenesis,tumor progression and metastasis.Nonresolving inflammation (NRI),a major driving factor in the occurrence and development of tumor,and MDSCs are present in tumor microenvironment and become hot topics in recent years.However,the relationships between MDSCs and NRI,especially in the relevant molecular regulatory networks,have not been fully elucidated.The relationships between MDSCs and NRI,the molecular regulatory networks,the key regulatory points and the strategies for targeted treatment are reviewed in this paper based on the current literatures and the work achieved by our research team.

Objective To study inflammatory cytokines changes in brain tissue of neonatal rats with periventricular leukomalacia (PVL).Method A total of 80 neonatal SD rats (P3) were randomly assigned into 2 equal groups,sham-operated group and PVL group.Rats in each group were further assigned into four subgroups (12,24,48,72 h),with 10 rats in each subgroup.The hypoxic-ischemic PVL modal were established following the procedure:first,isolation and ligation of left common carotid artery,and then exposed to 8％ O2 and 92％ N2 for 2.5 h.The sham-operated rats were processed with isolation of left common carotid artery only.Rats of the four subgroups were sacrificed at 12,24,48 h and 72 h respectively,then the brains were rapidly removed in corresponding time.Pathological changes of brain tissues were observed using HE stain.The mRNA expression levels of tumor necrosis factor α(TNF-α)and inter leukin-1β (IL-1β) were assessed using real-time quantitative PCR assays,the protein levels of TNF-α and IL-1β were detected using enzyme linked immunosorbent assay method.Result The brains tissues of rats in PVL group showed remarkably hyperemia and edema,with left ventricle enlargement.Periventricular white matter structure was disintegrated comparing with sham-operated group.The expression of TNF-α and IL-1 β mRNA in PVL group increased significantly,reaching peak by 24 h and then gradually decreased 72 h after the procedure.The mRNA levels of TNF-c and IL-1 β were significantly different between each two time points of 12,24 h and 48 h in PVL group (P ＜0.05).However,there was no differences between 72 h and 48 h within PVL and sham-operated group group(P ＞0.05).In PVL group,the protein expression trends of TNF-α and IL-1 β were similar to mRNA expression trends.Moreover,the protein levels were significantly different between each two time points of TNF-α and IL-1 β,respectively (P ＜ 0.01).The protein expression levels of TNF-α were different at each time point between PVL group and sham-operated group[(189.2 ± 20.4) pg/ml vs.(131.4 ±5.2) pg/ml at 12 h,(213.8 ± 16.7) pg/ml vs.(127.7 ±7.4) pg/ml at 24 h,(181.7 ± 15.0) pg/ml vs.(126.3 ± 6.0) pg/ml at 48 h,(159.6 ± 25.3) pg/ml vs.(131.4 ± 6.0) pg/ml at 72 h;P ＜0.01].The protein levels of IL-1β were different between the two groups only at 24 h and 48 h.[(121.8 ±30.0) pg/ml vs.(67.4 ± 13.7) pg/ml,(83.3 ± 15.7) pg/ml vs.(65.3 ± 14.9) pg/ml;P ＜0.05].In sham-operated group,no differences of TNF-α and IL-1 β protein levels were found between any different time points (P ＞ 0.05).Conclusion Inflammatory cytokines such as TNF-α and IL-1β are involved in ischemic-hypoxia induced PVL.Dynamic detection of inflammatory factors is expected to be an important method of early diagnosis,assessment of treatment efficacy and prognosis of PVL.
