ABSTRACT

Background: Less is known about the sexual life and information seeking of Chinese patients with prostate cancer (PCa) after androgen deprivation therapy (ADT) treatment. Aim: To identify the experiences of sex and information needs among Chinese patients with PCa after ADT treatment. Methods: This qualitative study included 15 Chinese patients with PCa in urology inpatient wards, selected via a purposive sampling method. Semistructured interviews were conducted face-to-face or by telephone regarding sexual experiences and information needs after ADT treatment. Outcomes: Themes and subthemes were assessed among patients with PCa. Results: Two themes and 5 subthemes emerged from the interview data. The first theme was "altered sexual life and attitude" with 3 subthemes: (1) undesirable sexual function and altered sexuality, (2) sexual attitudes and sociocultural cognition, and (3) behavior adjustment and intimacy. The second theme was "scarce information sources" with 2 subthemes: (1) uncertainty and lack of information support and (2) barriers to access sexual information. Clinical Implications: The present findings suggest that the following may help patients with PCa manage treatment and develop appropriate sexual attitudes: a tailored sexual health education program, well-equipped consultations rooms, and information delivery innovations. Strengths and Limitations: Strengths of this study included adding unique evidence among patients with PCa within an Asian context to reveal the understudied topic of sexual health and information needs after ADT treatment. This study was limited in being representative of all Chinese patients with PCa, with different marital statuses, treatment therapies, sexual orientations, and barriers of information seeking. Conclusion: Sexual life and attitude among patients with PCa were affected by their sociocultural cognition and ADT treatment, and most patients received insufficient information and sexual health education from health care providers.

ABSTRACT

OBJECTIVE: The objective of the study was to evaluate the clinical efficacy of kanglaite (KLT) injection combined with gefitinib versus gefitinib alone in the treatment of nonsmall cell lung cancer (NSCLC). METHODS: The randomized controlled trials involving NSCLC treatment with KLT injection combined with gefitinib versus gefitinib alone were searched on seven medical databases up to October 2016. Two reviewers independently assessed the methodological quality of the included studies. The RevMan 5.3 software was employed for data analysis. RESULTS: Seven randomized trials involving 554 patients met our criteria. Compared with gefitinib alone, KLT injection combined with gefitinib showed significant effects in increasing objective response rate (relative risk [RR] =1.38; 95% confidence interval [CI], 1.09-1.75), improving the performance status (RR = 1.80; 95% CI: 1.34-2.42), raising the percentages of CD4+ cells (weighted mean difference [WMD] = 4.45; 95% CI: 2.61-6.28), natural killer cells (WMD = 4.43; 95% CI: 3.85-5.01), and ratio of CD4+/CD8+ (WMD = 0.08; 95% CI: 0.02-0.14), whereas the difference was not significant in gefitinib toxicity including rash (RR 0.90; 95% CI: 0.58-1.40, P = 0.65), diarrhea (RR 1.04; 95% CI: 0.66-1.64, P = 0.88), and liver injury (RR 1.00; 95% CI: 0.58-1.73, P = 1.00), CD3+ cells (WMD = 1.16; 95% CI: -2.64-4.97) and CD8+ cells (WMD = 6.78; 95% CI: -1.68-15.23). CONCLUSION: Co-use of KLT injection and gefitinib may benefit the patients with NSCLC through enhancing the therapeutic effectiveness compared with gefitinib alone. To confirm these results, further rigorously designed trials are warranted.

ABSTRACT

H9N2 is the most prevalent low pathogenic avian influenza virus (LPAIV) in domestic poultry in the world. Two distinct H9N2 poultry lineages, G1-like (A/quail/Hong Kong/G1/97) and Y280-like (A/Duck/Hong Kong/Y280/1997) viruses, are usually associated with binding affinity for both α 2,3 and α 2,6 sialic acid receptors (avian and human receptors), raising concern whether these viruses possess pandemic potential. To explore the impact of mouse adaptation on the transmissibility of a Y280-like virus A/Chicken/Hubei/214/2017(H9N2) (abbreviated as WT), we performed serial lung-to-lung passages of the WT virus in mice. The mouse-adapted variant (MA) exhibited enhanced pathogenicity and advantaged transmissibility after passaging in mice. Sequence analysis of the complete genomes of the MA virus revealed a total of 16 amino acid substitutions. These mutations distributed across 7 segments including PB2, PB1, PA, NP, HA, NA and NS1 genes. Furthermore, we generated a panel of recombinant or mutant H9N2 viruses using reverse genetics technology and confirmed that the PB2 gene governing the increased pathogenicity and transmissibility. The combinations of 340 K and 588 V in PB2 were important in determining the altered features. Our findings elucidate the specific mutations in PB2 contribute to the phenotype differences and emphasize the importance of monitoring the identified amino acid substitutions due to their potential threat to human health.

ABSTRACT

Human bocavirus 1 (HBoV1) non-structural protein NS1 is a multifunctional protein important for virus replication and induction of apoptosis in host cell. To better understand the function of the NS1 protein, it is urgent to address reducing the toxicity of NS1 to host cells. In the present study, we established a stable cell line that regulates expression of NS1 of HBoV1. The recombinant lentivirus plasmid containing a regulatable promoter fused with ns1 gene was constructed and transfected into HEK 293T cells using transfection reagent. The HEK 293T cell lines stably expressing NS1-100 and NS1-70 proteins were established by screening resistant cells with puromycin and inducing NS1 expression with doxycycline. The expression of NS1 protein was determined by fluorescent labeling protein and Western blotting. HBoV1 promoter was transfected into stably expressing NS1 cell line and its trans-transcriptional activity was analyzed. The results showed that NS1 protein was expressed stably in the established cell lines and had a strong activation activity on the HBoV1 promoter driving luciferase gene. Taken together, this study provides a solid basis for further research on the function of NS1 and the pathogenesis of human bocavirus.
