Sexual experiences and information needs among patients with prostate cancer: a qualitative study.

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.

Ephedra Herb extract ameliorates adriamycin-induced nephrotic syndrome in rats via the CAMKK2/AMPK/mTOR signaling pathway / 中国天然药物

This study aimed to investigate the effect and mechanisms of Ephedra Herb (EH) extract on adriamycin-induced nephrotic syndrome (NS), providing an experimental basis for the clinical treatment of NS. Hematoxylin and eosin staining, creatinine, urea nitrogen, and kidn injury molecule-1 were used to evaluate the activities of EH extract on renal function. The levels of inflammatory factors and oxidative stress were detected by kits. The levels of reactive oxygen species, immune cells, and apoptosis were measured by flow cytometry. A network pharmacological approach was used to predict the potential targets and mechanisms of EH extract in the treatment of NS. The protein levels of apoptosis-related proteins and CAMKK2, p-CAMKK2, AMPK, p-AMPK, mTOR and p-mTOR in the kidneys were detected by Western blot. The effective material basis of EH extract was screened by MTT assay. The AMPK pathway inhibitor (compound C, CC) was added to investigate the effect of the potent material basis on adriamycin-induced cell injury. EH extract significantly improved renal injury and relieve inflammation, oxidative stress, and apoptosis in rats. Network pharmacology and Western blot results showed that the effect of EH extract on NS may be associated with the CAMKK2/AMPK/mTOR signaling pathway. Moreover, methylephedrine significantly ameliorated adriamycin-induced NRK-52e cell injury. Methylephedrine also significantly improved the phosphorylation of AMPK and mTOR, which were blocked by CC. In sum, EH extract may ameliorate renal injury via the CAMKK2/AMPK/mTOR signaling pathway. Moreover, methylephedrine may be one of the material bases of EH extract.

Transcriptomics analysis of hypoxia-induced retinal pigment epithelium cell injury / 中华实验眼科杂志

Objective:To analyze differentially expressed genes (DEGs) and the changes of signal pathways in human retinal pigment epithelium cells (ARPE-19) under hypoxic and normoxic conditions and to explore the biological mechanism of hypoxia-induced ARPE-19 cell damage via transcriptome sequencing (RNA-seq) and bioinformatics technology.Methods:The ARPE-19 cells were divided into the hypoxia treatment group and the normoxia control group treated with 1% and 21% O 2 by volume for 8, 24, 48, 72 hours, respectively.The relative expression levels of vascular endothelial growth factor (VEGF) and hypoxia-inducible factor-1α (HIF-1α) mRNA were detected with real-time fluorescent quantitative PCR at different time points.RNA-seq and bioinformatics analysis were performed at 8 hours and 24 hours after hypoxia and normoxia treatment.DEGs were screened out under the conditions of |log 2FC|≥1 and P≤0.05.Then the cluster heat map analysis, Gene Ontology (GO) functional enrichment analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis and protein-protein interaction network analysis were also carried out.Real-time fluorescent quantitative PCR was employed at 24 hours after hypoxia to detect the relative mRNA expression of genes that might be related to hypoxia in DEGs.Cell viability kit was used to verify and compare the damage effect of hypoxia on ARPE-19 cells at different time points between the two groups. Results:The relative mRNA expression levels of VEGF at 8, 24, 48 and 72 hours after hypoxia treatment and the relative HIF-1α mRNA expression levels at 8, 24 and 48 hours after hypoxia treatment were significantly higher than those of the normoxia control group (all at P<0.05). There were large differences in the mRNA expression levels at 8-hour and 24-hour treatment between the two groups.A total of 62 significant DEGs were screened between the hypoxia treatment group and the normoxia control group after 8-hour hypoxia treatment, among which 45 genes were significantly up-regulated and 17 genes were significantly down-regulated.A total of 255 significant DEGs were screened out between the hypoxia treatment group and the normoxia control group after 24-hour hypoxia treatment, among which 228 genes were significantly up-regulated and 27 genes were significantly down-regulated.The GO functional analysis of DEGs was mainly enriched in processes such as protein degradation, nucleotide biosynthesis, and material transport.KEGG pathway analysis was mainly enriched in PI3K-Akt, cGMP-PKG, and other signaling pathways closely related to metabolism, cell cycle, cell growth, and apoptosis.The core genes HPCA, MT3 and NOS3 were found by protein-protein interaction network analysis.Real-time fluorescent quantitative PCR test results showed that after 24-hour hypoxia treatment, the mRNA expression levels of hypoxia related genes DEPP1, NPPB, PDZK1, HILPDA, TCEA3, NDRG1 and RORC in ARPE-19 cells were significantly increased and the mRNA expression levels of TFRC and NQO1 were significantly decreased (all at P<0.05). The cell morphology was normal and the growth state was good without dead cells after 8-hour and 24-hour hypoxia treatment in ARPE-19 cells.There were dead cells after 48-hour hypoxia treatment, and the number of dead cells was increased at 72 hours after hypoxia treatment. Conclusions:The PI3K-Akt and cGMP-PKG signaling pathways related to metabolism may be involved in hypoxia-induced injury of ARPE-19 cells.Core genes of HPCA, MT3 and NOS3 can be used as functional target genes and play key roles in hypoxia response of cells.

Mechanism of action of bile acid metabolism in regulating cholestatic liver disease and the research and development of drugs / 临床肝胆病杂志

Bile acids are the end products of cholesterol metabolism and are classified as primary bile acids and secondary bile acids. They can promote nutrition absorption and regulate immune response, glucose/lipid/energy metabolism, and microbiota homeostasis by acting on bile acid nuclear receptors and membrane receptors. Cholestatic liver disease (CLD) is a type of liver disease caused by abnormalities of the hepatobiliary system due to cholestasis, with the initial manifestations of hepatocyte and/or bile duct injury, which further leads to abnormal bile acid synthesis, secretion, and excretion. In-depth studies have gradually revealed the role and mechanism of bile acids in CLD, and drugs targeting the action sites of bile acids are under research and development. This article elaborates on the role and mechanism of bile acid metabolism in CLDand summarizes the research and development of drugs for CLD treatment based on bile acid metabolism, so as to provide a reference for future research on the prevention and treatment of CLD.

Both frequency and duration of rotating night shifts are associated with metabolic parameters: a cross-sectional study.

BACKGROUND: Rotating night shift work contributes to the development of metabolic syndrome and relevant diseases. However, the contribution of different aspects of rotating night shift is rarely studied. AIM: This study investigated the association of frequency and duration of rotating night shift with metabolic parameters. METHODS: A cross-sectional study was conducted in nurses. Socio-demographic characteristics, duration and frequency of rotating night shifts, and metabolic parameters including body mass index (BMI), fasting blood glucose (FBG), blood pressure (BP), triglyceride, total cholesterol (TC), low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C), were collected. Sleep quality and perceived stress were assessed with Pittsburgh Sleep Quality Index (PSQI) and Perceived Stress Scale (PSS) respectively. Ratio of rotating night shift years to age (RRSYA) was calculated to present cumulative effect. Metabolic parameters were log-transformed and z-transformed in sequence. Multiple linear regressions were applied to explore the effect of frequency and RRSYA on metabolic parameters. Mediation analysis was used to estimate potential mediating effect of sleep quality and perceived stress. RESULTS: Frequency of rotating night shift work was significantly associated with elevated FBG and BMI, and decreased LDL-C. RRSYA was significantly associated with higher BMI, TC, LDL-C, BP and FBG. Sleep quality exhibited significant mediating effect between rotating night shift features and FBG and BMI. CONCLUSIONS: Our results suggest that frequency and RRSYA are associated with metabolic profile alterations, but the effects are different. Sleep quality appears to be an important mediator of the night shift's metabolic effect. Proper shift arrangement and sleep quality assurance may reduce the negative metabolic changes.

Prognostic value of difference between peripheral venous and arterial partial pressure of carbon dioxide in patients with septic shock: a pilot study / 南方医科大学学报

OBJECTIVE@#To evaluate the prognostic value of the difference between peripheral venous and arterial partial pressure of carbon dioxide in patients with septic shock following early resuscitation.@*METHODS@#This prospective study was conducted among the patients with septic shock treated in our department during the period from May, 2017 to May, 2018. Peripheral venous, peripheral arterial and central venous blood samples were collected simultaneously and analyzed immediately at bedside after 6-h bundle treatment. Arterial blood lactate concentration (Lac) and the arterial (PaCO), peripheral venous (PpvCO) and central venous partial pressure of carbon dioxide (PcvCO) were recorded. The differences between PpvCO and PaCO (Ppv-aCO) and between PcvCO and PaCO (Pcv-aCO) were calculated. Pearson correlation analysis was used to test the agreement between Pcv-aCO and Ppv-aCO. Multivariable logistic regression analysis was performed to analyze the possible risk factors for 28-day mortality, and the receiver-operating characteristic curve (ROC) was plotted to assess the prognostic values of these factors for 28-day mortality.@*RESULTS@#A total of 62 patients were enrolled in this study, among who 35 survived and 27 died during the 28-day period. Compared with the survivor group, the patients died within 28 days showed significantly higher Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score (24.2±6.0 20.5±4.9, =0.011), sequential organ failure assessment (SOFA) score (14.9±4.7 12.2±4.5, =0.027), PcvaCO (5.5±1.6 7.1±1.7, < 0.001), PpvaCO (7.1±1.8 10.0±2.7, < 0.001), and arterial lactate level (3.3±1.2 4.2±1.3, =0.003) after 6-h bundle treatment. Pearson correlation analysis showed that Ppv-aCO was significantly correlated with Pcv-aCO (=0.897, R= 0.805, < 0.001). Multiple logistic regression analysis identified Ppv-aCO (β=0.625, =0.001, OR=1.869, 95% CI: 1.311-2.664) and lactate level (β=0.584, =0.041, OR=1.794, 95%CI: 1.024-3.415) as the independent risk factors for 28-day mortality. The maximum area under the ROC (AUC) of Ppv-aCO was 0.814 (95%CI: 0.696- 0.931, < 0.001), and at the best cut- off value of 9.05 mmHg, Ppv-aCO had a sensitivity of 70.4% and a specificity of 88.6% for predicting 28-day mortality. The AUC of lactate level was 0.732 (95%CI: 0.607-0.858, =0.002), and its sensitivity for predicting 28-day mortality was 70.4% and the specificity was 74.3% at the best cut-off value of 3.45 mmol/L; The AUC of Pcv-aCO was 0.766 (95%CI: 0.642-0.891, < 0.001), and its sensitivity was 66.7% and the specificity was 80.0% at the best cut-off value of 7.05 mmHg.@*CONCLUSIONS@#A high Ppv-aCO after early resuscitation of septic shock is associated with poor outcomes. Ppv-aCO is well correlated with Pcv-aCO and can be used as an independent indicator for predicting 28-day mortality in patients with septic shock.

Objective To analyze the efficiency of perinatal group B streptococcal(GBS)infection preven-tion in the local area.Methods From June 2015 to June 2016,3 667 pregnant women were included.Both pre-natal examinations and deliveries were done in our hospital.The analysis of GBS colonization,risk factors and prevention of early-onset disease were done.Results Among preterm and term pregnant women,the rates of GBS screening were 23.4% and 35.6%,respectively.The positive results of GBS were 10.9% and 8.4%,re-spectively.The percentage of women with 2 risk factors were 22.9% and 0.3%,respectively.GBS screening has a better prediction effect for GBS colonization status of women at labor.There were significant differences in the intrapartum antibiotic prophylaxis(IAP)implementation between preterm and term pregnant women. In the IAP efficiency analysis of preterm,GBS colonization and risk factors,preterm had a high sensitivity (96.1%),while the specialties of GBS carry and risk factors were high(93.2% and 90.3% respectively).Con-clusion preterm pregnant women should be highlighted as an important population in the implementation of IAP.GBS screening strategy is better than the risk factors strategy.
