The effects of solid-state fermentation (SSF) and submerged fermentation (SmF) and the addition of olive oil on the whole-cell lipase production by Rhizopus chinensis CCTCC M201021 were investigated.Compared with SSF, higher biomass, hydrolytic activity and synthetic activity were observed in SmF.By the addition of olive oil, the synthetic activity of whole-cell lipase in both fermentations was enhanced significantly, especially in SmF, while the biomass and the hydrolytic activity were also increased.Hence, olive oil serves as both carbon source and the inducer of lipases in fermentation.It was also found that the synthetic activity of whole-cell lipase was not accordant to the hydrolytic activity during both SmF and SSF, suggesting that isoenzymes with difference in lipase properties may be produced by Rhizopus chinensis.

512?g/mL; MIC of 16 VIE to vancomycin were 16?g/mL; MIC of 8 VIE to vancomycin were 8?g/mL. It is a risk factor for hospital infection that VRE carriage of inpatients in intestinal tract is high. There is 100% agreement be-tween phenotypes and genotypes in 46 vancomycin resistance enterococci. VRE are multiresistant. Part iso-lates have high homology.

Objective To investigate the effect of cyclin-dependent kinase 2 (cdk2) recombinant lentivirus in rats with lipopolysaccharide (LPS)-induced acute lung injury (ALI).Methods Thirty-six adult SD rats were divided into control group, LPS model group and gene intervention group according to the random number table, with 12 rats per group.Rats with LPS-induced ALI were established by intratracheal injection of LPS.Saline solution (60 μL/kg) was injected in control group at the time point of 0, 24, 48 h respectively.Control-lentivirus (60 μL/kg) and cdk2 recombinant lentivirus (60 μL/kg) were injected respectively in LPS model group and gene intervention group at the time point of 0 h and 24 h.After 48 h, LPS (60 μL/kg) with isotonic saline solution were injected in both LPS model group and gene intervention group.Lung tissue samples from right-lower areas were collected at 24 h postinjury to evaluate the pathological changes with HE staining.Expressions of cdk2, clara cell secretory protein (CCSP), phospholipase A2(PLA2) and p-C/EBP β protein were detected by Western blot.Inflammatory factors of tumor necrosis factor-α(TNF-α), interleukin (IL)-1β, IL-6 and IL-10 in serum were measured with ELISA method.Results Inflammatory infiltration and damage to the alveolar structure were serious in LPS model group than control group, while inflammatory infiltration decreased significantly and alveolar structure tended to be normal in gene-intervention group.Expression of Cdk2 in control group (1.00±0.21) and LPS model group (0.93±0.17) were similar, but both were lower than that in gene intervention group (4.29±0.73) (P<0.05).Expression of CCSP in gene intervention group (3.19±0.38) was significantly higher than that in control group (1.00±0.20) and LPS model group (0.32±0.19) (P<0.05).Expression of PLA2 in LPS model group (4.49±0.51) was higher than that in control group (1.00±0.13) and gene intervention group (1.76±0.26) (P<0.05).Meanwhile, the variation of p-C/EBPβ concentration among the groups was similar to CCSP.Expression of TNF-α in LPS model group[(196.34±30.17)pg/ml] was higher than that in control group [(71.24±5.13)pg/ml] and gene intervention group[(86.32±11.02)pg/ml](P<0.05).Changes in IL-1β, IL-6 and IL-10 among the groups were similar to TNF-α.Conclusions Over-expression of Cdk2 plays a protective role for LPS-induced ALIby up-regulating CCSP and down-regulating inflammatory factors such as PLA2, TNF-α, IL-1β, IL-6 and IL-10, as may relate to the phosphorylation of C/EBPβ.

Objective : To investigate the epidemiological characteristics of influenza among the elderly in Heilongjiang Province from 2017 to 2021 (April 2017 to March 2022), so as to provide insights into influenza control among the elderly. Methods : The data pertaining to surveillance of patients with influenza-like illness (ILI) at ages of 60 years and older in Heilongjiang Province from 2017 to 2021 were retrieved from Chinese Influenza Surveillance Information Management, and the temporal distribution of ILI cases and the results of influenza virus tests were descriptively analyzed. Results : Totally 26 908 ILI cases at ages of 60 years and older were reported in Heilongjiang Province from 2017 to 2021, with an ILI prevalence rate of 0.17%. The prevalence of ILI appeared a tendency towards a rise in Heilongjiang Province from 2017 to 2021 (χ2trend=268.554, P<0.001), and the epidemic peaked in the 3rd to 7th weeks of 2019 and 2020. The overall positive rate of influenza virus was 6.80%, and the positive rate of influenza virus showed a tendency towards a decline from 2017 to 2021 (χ2trend=425.268, P<0.001). Influenza A (H1N1) pdm09 (46.82%) and A (H3N2) (22.79%), as well as influenza B virus lineages B/Victoria (12.11%) and B/Yamagata (18.28%) were predominant types, which changes among the study period. The detection of influenza virus-positive samples peaked from December to March of the next year, and a high positive rate of influenza virus was detected in Hegang (12.35%), Heihe (11.47%) and Daqing cities (11.07%). There was no significant correlation between the prevalence of ILI and the positive rate of influenza virus in Heilongjiang Province from 2017 to 2021 (rs=-0.800, P=0.104). Conclusions The prevalence of ILI appeared a tendency towards a rise among the elderly at ages of 60 years and older in Heilongjiang Province from 2017 to 2021, and the epidemic peaked in winter and spring. Influenza A (H1N1) pdm09, A (H3N2), B/Victoria, B/Yamagata were alternately prevalent and there was no obvious correlation between ILI prevalence and the positive rate of influenza virus.

Objective To apply the health education intervention based on protection motivation theory in community female patients with stress urinary incontinence,in order to establish a health behavior and to control urinary incontinence.Methods 96 female patients with stress urinary incontinence were randomly divided into the control group and the experimental group by random number table method,the control group received routine health education,the experimental group received health education based on protection motivation theory.The ICI-Q-SF score,pelvic muscle exercise compliance scale score,urinary incontinence coping efficacy score were compared between the control group and the experimental group.Results The ICI-Q-SF score of the experimental group after the intervention was 5.43 ± 1.77,which was significant lower than that in the control group,7.96±2.98,t=4.88,P＜0.01.The urinary incontinence coping efficacy scores of experiment groups after the intervention was 17.63±1.85,which was higher than that in the control group,13.49±2.46,t=-9.09,P＜0.01.There were 29 cases accounted for 63.04％ with good compliance and 17 cases accounted for 36.96％ with poor compliance in experimental group after intervention,14 cases accounted for 31.11％ with good compliance and 31 cases accounted for 68.89％ with poor compliance in control group after intervention,the difference was statistically significant,x2=9.306,P＜0.05.Conclusions Health education based on protection motivation theory can promote the coping efficacy and health behavior of community female patients with stress urinary incontinence and can effectively control urinary incontinence symptom.

OTX1 gene is one of the pivotal transcriptional factors involved in the neurogenesis.In order to overexpress the OTX1 gene in distinct cell types and find out its contribution to the proliferation and differentiation of stem cells in vitro,OTX1 cDNA was subcloned into lentiviral vectors.The resulting constructions pDUETOTX1,pDUETGFPOTX1 and pDUETGFP were packaged in 293 cells producing viral particles to transduce 293T cells,SY5Y cells,mouse embryonic stem cells and E15 neural stem cells.It was proved that the transferred OTX1 gene was located in the nuclei of the transduced cells in stead of plasma.Lentivirus is an ideal vector delivering gene to different cells.The overexpression of OTX1 in transduced 293T cells were validated by Western blot and immunofluorescence.
