Objective To investigate the expression of AR and its relationship with clinicopathological features in human epidermal growth factor receptor-2(Her-2) enrich breast cancer. Mehtods The expression of AR was detected by immunohistochemical staining in 102 patients with Her-2 enrich breast cancer. The relationship between AR expression and its clinicopathological characteristics was analyzed. Results The positive rate of AR expression was 75.5%. Patients in the positive group had a lower level of lymph nodes and Ki-67 value (P < 0.05). However, no significant differences of AR expression were observed in age, menopausal status, tumor size, histological grade, vessel invasion, P53 and PCNA (P > 0.05). Conclusion AR was highly expressed in Her-2 enrich breast cancer, which may be a potential target for treatment of Her-2 enrich breast cancer.

Objective: To investigate the effect of interleukin-22 (IL-22) on the activation and proliferation of hepatic stellate cells (HSCs) induced by acetaldehyde, as well as the role of the antioxidant axis Nrf2-keap1-ARE. Methods: Hepatic stellate cell-T6 (HSC-T6) cells were cultured in vitro, and after 24 and 48 hours of acetaldehyde stimulation at various concentrations (25, 50, 100, 200, and 400 μmol/L), MTT assay was used to measure cell proliferation rate to screen out the optimal conditions for model establishment. HSC-T6 cells were treated first with the optimal concentration of acetaldehyde (200 μmol/L) for 24 hours and then with different concentrations of IL-22 (10, 20, and 50 ng/ml) for 24 hours. MTT assay was used to measure cell proliferation, Western blot and cell immunohistochemistry were used to measure the expression of nuclear factor erythroid 2-related factor 2 (Nrf2) and α-smooth muscle actin (α-SMA), and spectrophotometry was used to measure the changes in the content of malondialdehyde (MDA) and reduced glutathione (GSH) in culture supernatant. SPSS 17.0 was used for statistical analysis and data were expressed as mean±SD. P < 0.05 was considered statistically significant. A one-way analysis of variance was used for comparison of means between any two groups. Results: HSCs had significantly enhanced proliferation and activation after being treated with acetaldehyde, especially at 200 μmol/L for 48 hours. After the intervention with gradient concentrations of IL-22, the proliferation and activation of HSCs were inhibited in a dose-dependent manner, and the proliferation and migration rates in the 10, 20, and 50 ng/ml IL-22 groups were 14%, 25%, and 35%, respectively (all P < 0.05). The results of Western blot and immunohistochemistry showed that there was no significant difference in the expression of Nrf2 total protein in HSCs between groups, while there was extremely low expression of Nrf2 nucleoprotein in the blank control group. There was increased expression of Nrf2 nucleoprotein after acetaldehyde stimulation (compared with the blank control group, P < 0.05), and after the intervention with gradient concentrations of IL-22, the expression of Nrf2 nucleoprotein was further increased (all P < 0.05). The results of spectrophotometry showed that compared with the blank control group, the model group had increased levels of MDA and GSH in culture supernatant after acetaldehyde stimulation; after the intervention with gradient concentrations of IL-22, there was a significant reduction in the MDA level and a significant increase in the GSH level in a dose-dependent manner (all P < 0.05). Conclusion The activation and proliferation of HSCs induced by acetaldehyde helps with the successful establishment of an in vitro model of alcoholic liver fibrosis. IL-22 effectively inhibits the activation and proliferation of HSCs induced by acetaldehyde, and its mechanism may be related to promoting Nrf2 nuclear translocation in HSCs and expression of the downstream target gene GSH and increasing the activity of the antioxidant axis Nrf2-keap1-ARE.

Objective To investigate the effects of putative bacteriocin immunity proteins on the growth mode of Streptococcus mutans(Sm). To observe the differences of antimicrobial sensitivity in planktonic Sm wild-type strains and mutant strains caused by the inactivation of bacteriocin immunity proteins and their influence on the biofilm formation. Methods Sm wild-type strains(WT) and its knockout mutants defective in immA and immB(△immA- and △immB- mutants) coding putative bacteriocin immunity proteins were cultured in brain heart infusion (BHI) and selected by erythromycin at the concentration of 10 mg/L. Optical density was detected by spectrophotometer every hour and growth curve was drawn. WT, △immA- and △immB- mutants were treated with ampicillin(0.04, 0.05, 0.06, 0.07, 0.08 mg/L), sodium fluoride(50, 100, 150, 200, 250 mg/L) and sodium hypochlorite(0.078%, 0.156%, 0.313%, 0.625%, 1.250%) for 24 hours. Optical density was detected by multifunctional micro plate reader. WT and the mutants were cultured in MBECTM P&G Assay for 24 hours. The minimum biofilm eradication concentration(MBEC) of chlorhexidine against Sm was determined by serial dilution method. Confocal laser scanning microscopy(CLSM) was used to visualize the biofilm architecture, depth and ratio of live to dead bacteria. Results Growth curve showed that it took about 3 hours to reach exponential phase and about 7 hours to stationary phase for WT, while 4 hours to exponential phase and 8 hours to stationary phase for mutants. Optical density of mutants were lower than WT in the presence of various antimicrobial agents (P<0.01). In 0.06 mg/L ampicillin group, optical density value of WT, △immA- and △immB- mutants were 0.334±0.016, 0.027±0.016 and 0.047±0.018. In 150 mg/L sodium fluoride group, optical density value of WT and mutants were 0.254±0.018, 0.129±0.011 and 0.167±0.010. In 0.313% sodium hypochlorite group, optical density value of WT and mutants were 0.467±0.008, 0.017±0.006 and 0.050±0.006. The MBEC of chlorhexidine against Sm WT, △immA- and △immB- mutants were 6.25,1.57,and 3.13 mg/L. The results by CLSM showed a noticeable difference in biofilm architecture. The depth of WT biofilm was higher than the mutants biofilm(P<0.01). The ratio of live to dead bacteria of WT biofilm was higher than △immA- mutants in all layers(P<0.05) and △immB- mutants in the outer and intermedium layer(P<0.01). There is no significant different between the inner layers of WT and △immB- mutants(P=0.191). Conclusions Putative bacteriocin immunity proteins have influence on the growth mode of Sm. The antimicrobial sensitivity of planktonic Sm can be up-regulated by the inactivation of immA or immB. The MBEC of chlorhexidine against △immA- and △immB- mutants is lower than WT. The inactivation of immA or immB affects the biofilm formation.

Objective:To explore the mediating effect of social support on social avoidance and distress and reproductive concerns in young breast cancer patients undergoing chemotherapy.Methods:This is a cross-sectional study. From February 2020 to December 2021, a total of 180 young breast cancer patients undergoing chemotherapy in Shandong Cancer Hospital were selected as the research objects using the convenient sampling method. General Data questionnaire, Social Support Rating Scale, Reproductive Concerns After Cancer Scale (RCAC) and Social Avoidance and Distress Scale (SADS) were used to investigate patients. Pearson correlation analysis was used to investigate the correlation among social support, social avoidance, distress and reproductive concerns in young breast cancer patients undergoing chemotherapy. Structural equation models was used to explore the mediating effect of social support between social avoidance and distress and reproductive concerns. A total of 180 questionnaires were distributed in this study, and 172 were effectively received, with an effective recovery of 95.56% (172/180) .Results:The total score of SADS of young breast cancer patients undergoing chemotherapy was (18.98±3.15), the total score of RCAC was (59.85±5.03), and total score of Social Support Rating Scale was (33.53±4.25). Pearson correlation analysis results showed that social avoidance, distress was positively correlated with reproductive concerns ( r=0.810, P<0.01), and social support was negatively correlated with reproductive concerns and social avoidance and distress ( r=-0.570, -0.612; P<0.01). Structural equation model results showed that social support played a partial mediating role between social avoidance and distress and reproductive concerns. Conclusions:Social support plays a mediating effect between social avoidance and distress and reproductive concerns in young breast cancer patients undergoing chemotherapy. Medical and nursing staff should provide more social support for young breast cancer patients undergoing chemotherapy, reduce reproductive concerns and improve quality of life.

A total of 100 HIN1 flu real-time-PCR positive throat swabs collected from fever patients in Zhejiang,Hubei and Guangdong between June and November 2009,were provided by local CDC laboratories.After MDCK cell culture,57 Influenza A Pandemic (H1N1) viruses were isolated and submitted for whole genome sequencing.A total of 39 HA sequences,52 NA sequences,36 PB2 sequences,31 PB1 sequences,40 PA sequences,48 NP sequences,51 MP sequences and 36 NS sequences were obtained,including 20 whole genome sequences.Sequence comparison revealed they shared a high degree of homology (96％～99％) with known epidemic strains (A/Califomia/04/2009(H1N1).Phylogenetic analysis showed that although the sequences were highly conserved,they clustered into a small number of groups with only a few distinct strains.Site analysis revealed three substitutions at loop 220 (221-228) of the HA receptor binding site in the 39 HA sequences:A/Hubei/86/2009 PKVRDQEG→PKVRDQEA,A/Zhejiang/08/2009 PKVRDQEG→PKVRDQER,A/Hubei/75/2009PKVRDQEG→PKVRDQGG,the A/Hubei/75/2009 was isolated from an acute case,while the other two were from patients with mild symptoms.Other key sites such as 119,274,292 and 294 amino acids of NA protein,627 of PB2 protein were conserved.Meanwhile,all the M2 protein sequences possessed the Ser32Asn mutation,suggesting that these viruses were resistant to adamantanes.Comparison of these sequences with other H1N1 viruses collected from the NCBI database provides insight into H1N1 transmission and circulation patterns.
