Expression and significance of CD44 and p-AKT in pancreatic head cancer.

BACKGROUND: CD44 and phosphorylated AKT (p-AKT) is a potentially interesting prognostic marker and therapeutic target in pancreatic cancer. The expression of CD44 and p-AKT has been reported to correlate with poor prognosis of pancreatic cancer in most literatures. The purpose of this study is to investigate the roles of CD44 and p-AKT in pancreatic head cancer and their correlation with the prognosis of pancreatic head cancer patients. METHODS: Forty-eight pancreatic head cancer samples were collected dating from Jan. 2010 to Dec. 2012. Immunohistochemistry was applied to test the expression of CD44 and p-AKT in pancreatic head cancer. The clinical data of the patients were collected including their gender, age, the histology and location, lymph node metastasis, and so on. The correlation between the CD44 expression and the clinicopathological factors of patients with pancreatic head cancer was analyzed by the software SPSS 13.0. RESULTS: The positive rates of CD44 and p-AKT expression in the samples were 64.6 and 29.2 %, respectively. There was a significant difference between the CD44 expression and the pancreatic cancer' T staging, tumor node metastasis (TNM) staging, lymph node metastasis (P < 0.05). The Cox proportional hazard model showed that CD44 and lymph node metastasis were independent prognostic factors. CONCLUSIONS: CD44 was related to the distant metastasis and aggressive malignant behaviors of pancreatic head cancer.

Comparison of Microbial Populations in the Blood of Patients With Myocardial Infarction and Healthy Individuals.

Increased bacterial translocation in the gut and bloodstream infections are both major comorbidities of heart failure and myocardial infarction (MI). However, the alterations in the microbiome of the blood of patients with MI remain unclear. To test this hypothesis, we conducted this case-control study to explore the microbiota compositions in the blood of Chinese patients with MI. Using high-throughput Illumina HiSeq sequencing targeting the V3-V4 region of the 16S ribosomal RNA (rRNA) gene, the microbiota communities in the blood of 29 patients with MI and 29 healthy controls were examined. In addition, the relationship between the blood microbiome and clinical features of MI was investigated. This study revealed a significant reduction in alpha diversity (Shannon index) in the MI group compared with the healthy controls. Also, a significant difference was detected in the structure and richness between the patients with MI and healthy controls. The members of the phylum Actinobacteria, class Actinobacteria, order Bifdobacteriales, family Bifidobacteriaceae, and genus Bifidobacterium were significantly abundant in the MI group, while the members of the phylum Bacteroidetes, class Bacteroidia, and order Bacteroidales were significantly enriched in the healthy controls (p < 0.05). Moreover, the functional analysis revealed a significant variation between both groups. For instance, the enrichment of genes involved in the metabolism pathways of three amino acids decreased, that is, nucleotide transport and metabolism, coenzyme transport and metabolism, and lipid transport and metabolism, among others. Our study will contribute to a better knowledge of the microbiota of blood, which will further lead to improved MI diagnosis and therapy. Further study is needed to determine the role of the blood microbiota in human health and disease.

Analysis of nurses' job burnout and coping strategies in hemodialysis centers.

In recent years, nursing has come to be considered a high-risk and high-pressure profession, given the fast-paced working environment and constant need to handle emergencies, especially for nurses working in hemodialysis centers. Nearly every day, nurses are confronted with life and death situations and are required to provide skilled, high quality care for their patients, in fast-paced and demanding environments. Thus, nurses are susceptible to both psychological stress and other mental health problems, making them more vulnerable to burnout when compared against other healthcare professions.An anonymous online questionnaire was completed by a group of participating nurses, using the web-based survey platform WeChat. Registered nurses working in hemodialysis centers were randomly selected from 5 comprehensive tertiary level hospitals in Sichuan Province, China. The data collection instrument comprised two parts: demographic data and a nurse burnout questionnaire-the Maslach Burnout Inventory. Overall, 70 nurses were invited to participate, with 65 returning completed questionnaires, giving a response rate of 92.9%. In this survey, the burnout level was set at28.15 ±â€Š12.39 for emotional exhaustion (EE), 10.23 ±â€Š5.47 for depersonalization (DP), and 37.19 ±â€Š8.31 for personal accomplishment (PA)-EE and DP levels are found to be high at the level of burnout.Job burnout was found to exist widely among the nurses of hemodialysis centers, which may then result in adverse effects on their physical and mental health. Active interventions can significantly reduce job burnout and also help maintain the stability of nursing workforce levels.

Burnout level and job satisfaction in Chinese pediatrics residents: A web-based cross-sectional study.

To study the prevalence of burnout and job satisfaction in Chinese pediatrics residents.Prospective participants were invited via a WeChat group to participate from October 1, 2018 to January 31, 2019. The Maslach Burnout Inventory-Human Services Survey was used to measure physician burnout, and the Minnesota Satisfaction Questionnaire was used to measure job satisfaction.A total of 380 residents (81.1% response rate) from 35 pediatric residency programs completed the cross-sectional web-based survey. Of the responders, 233 (61.3%) exhibited high levels of career burnout. Residents 24 to 29 years of age were less likely to report burnout than residents ≥30 years of age (50.9% vs74.7%; P < .05). In addition, residents with an annual income less than 80,000 RMB seem to have higher burnout levels (66.2%). Residents who reported that they felt sleep deprived had significantly higher rates of burnout than those who did not (P < .01). Logistic regression showed that age ≥30 years (odds ratio [OR] 3.74 [1.57-7.66], P < .01) and sleep deprivation (OR 4.11 [2.19-7.35], P < .01) were the 2 independent risk factors associated with burnout.Burnout is highly prevalent among Chinese pediatrics residents who also reported poor job satisfaction.

Transcription Factor SOX18 Promotes Clear Cell Renal Cell Carcinoma Progression and Alleviates Cabozantinib-Mediated Inhibitory Effects.

The transcription factor SOX18, which was initially discovered as an activator of genetic transcription during embryogenesis, is now implicated in many diseases, including cancer, and is associated with the malignant tumor phenotype, angiogenesis, and lymphangiogenesis. However, the role of SOX18 in clear cell renal cell carcinoma (ccRCC) is not well understood. In the current study, SOX18 expression was evaluated in a 250 case-cohort of primary ccRCC tissues that included 103 cases of matched normal kidney tissues and 21 cases of metastatic tissues. Functional and mechanistic analyses were performed in cells that had SOX18 either overexpressed or silenced to evaluate the effects of SOX18 on cell function, the cellular response to cabozantinib, and SOX18-mediated molecular mechanisms. Our data revealed that upregulation and nuclear translocation of SOX18 promoted ccRCC carcinogenesis and metastasis. Elevated SOX18 expression was associated with advanced pathologic grades and TNM stages, as well as poor patient survival. SOX18 also regulated the cell cycle and the epithelial-mesenchymal transition to promote the malignant phenotype in ccRCC cells. The activation of EGF/EGFR and HGF/c-MET signaling in vitro and in vivo was induced by SOX18. Moreover, SOX18 activation bypassed the inhibitory effects of cabozantinib on cell proliferation, migration, and invasion. In conclusion, our data indicate that SOX18 may be a promising therapeutic target for ccRCC treatment.

Investigation of posttraumatic stress disorder in children after animal-induced injury in China.

OBJECTIVE: Dogs are important members of many families in many countries. However, posttraumatic stress disorder (PTSD) in children after animal attacks has always been underestimated, and a more-detailed study of PTSD in children after animal attacks is needed. METHODS: The charts and follow-up data for 358 children after animal-induced injuries were reviewed. Family Apgar Scale assessment and PTSD screening were performed at emergency department admission. On week 1 after the emergency department admission, the patient underwent evaluation for acute stress disorder (ASD) diagnosis, by using the Child Acute Stress Questionnaire. PTSD screening and interim history-taking were performed 3 months after the emergency department admission, by telephone or in face-to-face interviews, by using the Clinician-Administered PTSD Scale for Children and Adolescents. P values of <.05 were considered significant. RESULTS: A total of 19 patients developed PTSD, including 10 patients with severe injuries, 8 patients with moderate injuries, and 1 patient with a mild injury (chi(2)=48.104; P=.000). No significant differences in PTSD occurrence according to gender and age were observed. Family Apgar Scale scores were not significantly related to PTSD (P=.781). ASD and PTSD symptom severity scores were significantly associated (r=0.51; P < .005). CONCLUSIONS: Child victims of severe animal attacks should be considered at risk for the development of PTSD, family support was not correlated with posttraumatic stress symptoms in school-aged children after animal attacks, and ASD seems to be an early predictive indicator of PTSD.

A catalog for transcripts in the venom gland of the Agkistrodon acutus: identification of the toxins potentially involved in coagulopathy.

Agkistrodon acutus is a special agkistrodon halys, only distributed in Southern China, with a few exceptions in Vietnam. It is a cherished element used in traditional Chinese medicine. In order to produce a global panorama of gene expression in the Agkistrodon acutus venom gland, a non-normalized cDNA library was constructed, and 8696 high quality 5' end expressed sequenced tags (ESTs) were sequenced and analyzed. The initial sequences were assembled into 2855 clusters. Of these clusters, only 45.60% clusters matched known sequence and 54.40% had no match to any known sequence in GenBank. Except for putative cellular proteins (1184 clusters), the remaining 118 clusters (40.16% of all ESTs) corresponded to sequences associated with diverse toxin function. According to expression abundance, the major toxin components were metalloproteinases (32.08%) and C-type lectin (5.22%), and other components including bradykinin-potentiating peptide (0.90%), serine proteases (0.51%), nucleotidase and nuclease (0.41%), phospholipase A2 (0.30%), disintegrin (0.05%), cytokine-like molecules (0.06%), and other proteins (0.63%). The majority of these components are thought to be responsible for coagulopathy after A. acutus bites. We have therefore generated a comprehensive catalog of the A. acutus venom gland described so far. Gene expression from the very specialized secretory tissue, especially for those involved in coagulopathy, can be surveyed and provide important information in finding novel toxins.
