A nurse-led multidomain intervention to improve the management of chemotherapy-induced nausea and vomiting in patients with head and neck cancers: A randomized controlled trial.

PURPOSE: This study aimed to investigate the effect of a nurse-led multidomain intervention on chemotherapy induced nausea and vomiting (CINV) in patients with head and neck squamous cell carcinomas (HNSCC). METHODS: Ninety-two HNSCC patients who received cisplatin-based chemotherapy were divided into intervention group (n = 45) and control group (n = 47). The control group received usual care of CINV, which consisted of administration of antiemetics according to physicians' preference, education about CINV control and dietary recommendations provided by primary nurses. The intervention group received nurse-led, evidence-based multidomain management, including nurse-led CINV risk factors assessment, education on prevention and control of CINV, antiemetics following guidelines, dietary strategies, and relaxation therapy. The number of patients who experienced CINV was collected. The severity of CINV was graded according to the Common Terminology Criteria for Adverse Events v3.0. The influence of CINV on patient's quality of life was assessed by the Functional Living Index-Emesis (FLIE). RESULTS: The incidence and the severity of nausea and vomiting in the intervention group were significantly lower than those in the control group within 5 days after chemotherapy, and the scores of the dimension of nausea and vomiting in the intervention group were significantly higher than those in the control group [63.00 (50.00-63.00) vs 40.00(28.00-63.00), 63.00(63.00-63.00) vs 63.00 (43.00-63.00)], the differences were statistically significant (P < 0.05). CONCLUSIONS: Nurse-led multidomain intervention can reduce the incidence and the severity of CINV in patients with HNSCC who were treated with cisplatin-based chemotherapy, and thus reduced the influence of CINV on patients' quality of life. THE CLINICAL TRIAL REGISTRATION NUMBER: NCT05792228.

Yueju volatile oil plays an integral role in the antidepressant effect by up-regulating ERK/AKT-mediated GLT-1 expression to clear glutamate.

Phytochemical investigation of the volatile oil of Yueju (YJVO) and its constituent herbs induced the detection of 52 compounds in YJVO, mainly monoterpenes and sesquiterpenes as well as a small amount of aromatic and aliphatic compounds. 5 of these compounds were found only in the YJVO instead of the volatile oil of its constituent herbs. The anti-depressant effect of YJVO was proved by behavioral tests in chronic unpredictable mild stress (CUMS) mice. An acute oral toxicity evaluation determined the LD50 of YJVO was 5.780 mL/kg. Doppler ultrasound and laser speckle imaging have detected that the YJVO could improve depression-related cerebral blood flow. In addition, related neurotransmitters and proteins were analyzed through targeted metabolomics and immunofluorescence. The potential antidepressant mechanisms of YJVO related to significantly decreasing Glu in CUMS mice by up-regulating the ERK/AKT-mediated expression of GLT-1.

Health-Related Quality of Life and Thyroid Cancer-Specific Symptoms in Patients Treated for Differentiated Thyroid Cancer: A Single-Center Cross-Sectional Survey from Mainland China.

Background: The incidence of differentiated thyroid cancer in Mainland China has increased rapidly in recent years, yet the number of studies focusing on health-related quality of life (HR-QOL) is still limited. Additionally, some of the quality-of-life (QOL) issues specific to thyroid cancer have not been adequately described. The aims of this study were to assess the generic and disease-specific HR-QOL of differentiated thyroid cancer survivors and to identify the associated factors. Methods: A cross-sectional survey including 373 patients was conducted in Mainland China. Participants completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), the Thyroid Cancer-Specific Quality of Life Questionnaire (THYCA-QOL), and a questionnaire on patient demographics and clinical characteristics. Results: The QLQ-C30 global mean score was 73.12 (standard deviation [SD] = 11.95), while the THYCA-QOL summary mean score was 34.50 (SD = 12.68). The two QLQ-C30 functional subscales with the lowest scores were the social functioning and role functioning subscales. The five symptom subscales of the THYCA-QOL with the highest scores were the subscales regarding less interest in sex, problems with scar, psychological problems, voice problems, and sympathetic problems. Factors associated with worse global QOL on the QLQ-C30 included a shorter time since completing primary treatment (≤6 months), a history of lateral neck dissection, and a lower current thyrotropin (TSH) level (≤0.5 mIU/L). Higher cumulative activities of radioiodine (RAI; >100 mCi), gender (women), postoperative hypoparathyroidism, and a history of lateral neck dissection were associated with worse thyroid cancer-specific QOL. In contrast, higher monthly household income (>5000ï¿¥) and a history of minimally invasive thyroid surgery were associated with better thyroid cancer-specific QOL. Conclusions: Thyroid cancer patients experience multiple health-related problems and disease-specific symptoms after completing primary treatment. Patients with a duration ≤6 months from the completion of primary treatment, those with a history of lateral neck dissection, and a current TSH level ≤0.5 mIU/L may be more likely to have impaired generic QOL. More thyroid cancer-specific symptoms may be associated with higher cumulative activities of RAI, gender (women), postoperative hypoparathyroidism, a history of lateral neck dissection, lower monthly household income, and conventional surgery.

Two Species Origins Comparison of Herba Patriniae Based on Their Ingredients Profile by UPLC-QTOF/MS/MS and Orthogonal Partial Least Squares Discriminant Analysis.

Herba Patriniae (HP) is widely used as a medicinal and edible material in China. Besides food value, HP attracts more attention due to its medicinal potential. Patrinia villosa Juss. (PV) and Patrinia scabiosaefolia Fisch. (PS) are the two species origins of HP. These two of HP show different effects on cell proliferation, migration, angiogenesis and anti-diabetic. As we have previously reported, PV and PS show significant differences on their anti-inflammatory ability in the same experimental model. Comparing the ingredient profiles of two different sources will not only facilitate the understanding of their medicinal effects, but also help the development and research of new activities. However, still now, there is no systematic and detailed study to compare the components of PV and PS. In present study, ultra-high performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry was employed to achieve a high-throughput qualitative and thorough analysis of the chemical composition spectrum of HP. A total of 164 compounds were identified, among these compounds, 127 compounds were identified from PV, and 107 compounds were identified from PS. Most of the chemical components was discovered for the first time. Flavonoids, saponins, terpenoids and organic acids, as the main ingredients in PV and PS were 45.45 %vs 28.46 %, 12.61 % vs. 32.09 %, 14.33 % vs. 22.38 % and 14.58 % vs. 6.79 %, respectively. Flavonoids are the main components of PV, while PS is rich in saponins. PV and PS were classified into two groups by principal component analysis (PCA) and screened out the main molecular differences responsible by orthogonal partial least squares discriminant analysis (OPLS-DA). All the results will be a guide for the quality control, functional activity research, or better clinic use based on the ingredients profile between these two species. Besides, this first study on ingredients profile of two species origins will be beneficial for potential and best resources utilization of both PV and PS.

Study on the new anti-atherosclerosis activity of different Herba patriniae through down-regulating lysophosphatidylcholine of the glycerophospholipid metabolism pathway.

BACKGROUND: Atherosclerosis (AS) is a multifactor cardiovascular disease characterized by chronic inflammation. The safety of long-term medication is the focus of clinical treatment selection and application. It is urgent to develop more high-efficiency and low side effects drugs to treat AS. Therefore, the screening of anti-AS drugs with high efficiency and low toxicity from phytomedicine has attracted more and more attention. PURPOSE: The aim of this study was to explore the new pharmacological effect of Herba patriniae against AS, to find the best origin and extraction part of Herba patriniae, furthermore, to reveal its potential action mechanism. METHODS: Apolipoprotein E gene-knockout (ApoE-/-) mice were orally administered with different extracts of Patrinia villosa Juss (PVJ) and Patrinia scabiosaefolia Fisch (PSF). Their anti-AS effect was comprehensively evaluated by small animal ultrasound, HE staining, Oil-Red O staining, platelet aggregation rate and blood lipid level. Lipid metabolomics and network pharmacology were used to study the mechanism of drug action. Finally, the expression of related proteins were detected by western blots and immunofluorescence. RESULTS: PVJ EtOAc extract and PSF EtOAc extract could significantly reduce vascular plaque, liver inflammation, platelet aggregation and blood lipid levels in AS model. By comparison, the effect of PVJEE was better than that of PSFEE. Furthermore, the results of differential metabolites indicated that PVJEE may inhibit the apoptosis of vascular endothelial cells, proliferation and migration of smooth muscle cells by reversing lysophosphatidylcholine (LPC) in the glycerophospholipid metabolic pathway, so as to play an anti-AS role. This result was double verified by KEGG based metabolic pathway enrichment analysis and related protein expression study. CONCLUSION: By changing glycerophospholipid metabolism pathway, Herba patriniae can significantly regulate lipid metabolism and inflammatory level, showing the development potential of anti-AS, which provides new candidate drugs and good prospects for the safe treatment of AS. In addition, through comparison, this study also confirmed that PVJEE was the best origin and extraction part of anti-AS.

Pulchinenosides: Correlation of surface activity-cytotoxicity and hepatocyte apoptosis mechanism study.

Saponin is an active component of many phytomedicine, which has extensive pharmacology effects. Meanwhile, it is reported that cytotoxicity, especially hemolysis and hepatotoxicity, in pentacyclic triterpenoid saponin (PTS) hindered their further development and application. Surface activity, a unique physical property of saponins, is believed to be related to membrane toxicity. However, the correlation between the surface activity and cytotoxicity of saponins is still unexplained. In this paper, our aim was to explore the relationship between surface activity-cytotoxicity of pulchinenosides and the hepatotoxicity mechanism of PTS in vitro. The surface activity of different saponins was investigated by contact angle, surface free energy (SFE), and oil/water partition coefficient (log Papp). In the cytotoxicity study, the hemolysis and hepatotoxicity activity of different saponins was compared by HD50 of erythrocyte and MTT, flow cytometry and LDH assay in LO2 cells respectively. And in the hepatotoxicity mechanism study, western blot was used for observing the expression of proteins related to apoptosis and exploring the liver injury mechanism of PTS. The results suggested that the influences of surface activity on hepatocytes and erythrocytes were different, indicating that the correlation of surface activity-cytotoxicity could provide more information for development of PTS. And the result of hepatotoxicity mechanism study of saponins suggested that endogenous and exogenous apoptotic pathways could be the potential targets of PTS, which could not only provide basis for clinical monitoring and treatment of the toxicity in saponins, but also provide more reference for the clinical application of PTS and phytomedicine containing PTS.

Validation of the Thyrotoxicosis-associated Insomnia Model Induced by Thyroxine through Sympathetic Stimulation: Face, Construct and Predictive Perspectives.

Insomnia has become a common central nervous system disease. At present, the pathogenesis of insomnia is not clear. Animal models can help us understand the pathogenesis of the disease and can be used in transformational medicine. Therefore, it is very necessary to establish an appropriate model of insomnia. Clinical data show that insomnia patients with high levels of thyroxine and often accompanied by cardiovascular problems, a common mechanism underlying all of these physiological disruptions is the sympathetic nervous system. Combined with the characteristics of chronic onset of clinical insomnia, an insomnia model induced by long-term intraperitoneal injection of thyroid hormone has been created in our laboratory. In this paper, the insomnia-like state of the model was evaluated based on three validity criteria. Face validity has been demonstrated in metabolism, the Morris water maze, electrocardiogram (ECG) and electroencephalogram (EEG). Structure validity has been proved by the results of targeted metabolomics. After treatment with diazepam, a commonly used clinical anti-insomnia drug, the above physiological and pathological disorders were reversed. The results of comprehensive analysis show that the established thyrotoxicosis-associated insomnia model meets the validity requirement to establish an appropriate animal model of insomnia. The model presented in this article might help to study pathogenetic mechanisms of clinical insomnia, as well as to test promising methods of insomnia treatment.

Hydrophilic SiC hollow fiber membranes for low fouling separation of oil-in-water emulsions with high flux.

The dry-wetting spinning technique involving immersion-induced phase inversion and dry-sintering was applied to prepare two types of SiC and Al2O3 hollow fiber membranes. The two hollow fiber membranes were characterized in terms of morphology and chemical surface composition by scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), water contact angle and zeta potential measurements. The filtration capabilities of the two hollow fiber membranes were assessed by the separation of 200 mg L-1 synthetic (O/W) emulsions. During the treatment of O/W emulsions, the permeation flux of the SiC hollow fiber membrane was 163.9 L h-1 m-2, which was higher than that of the Al2O3 hollow fiber membrane (139.4 L h-1 m-2) at the beginning of the experiment. The membrane surface properties and the filtration results of O/W emulsion microfiltration demonstrated that the SiC hollow fiber membranes with a higher hydrophilicity had higher water flux and better anti-fouling properties.

Body image and its associated factors among Chinese head and neck cancer patients undergoing surgical treatment: a cross-sectional survey.

PURPOSE: Body image is a critical psychosocial issue for patients with head and neck cancer. However, the current status and associated factors of body image in patients with head and neck cancer in Mainland China remain unknown. This study aimed to explore body image concerns for head and neck cancer patients undergoing surgical treatment in Mainland China and to identify the associated factors. METHODS: A cross-sectional study was conducted including 154 patients who underwent surgery for head and neck cancer at Tianjin Medical University Cancer Institute & Hospital in Mainland China. Participants were surveyed using the Body Image Scale (BIS), the Perceived Social Support Scale (PSSS), the Simplified Coping Style Questionnaire (SCSQ), the Hospital Anxiety and Depression Scale (HADS), and a questionnaire designed for this study. The Mann-Whitney U test, Kruskal-Wallis H test, Spearman's rank correlation, and stepwise multiple regression analysis were used to analyze the data. RESULTS: The score of BIS was 6.00 (4.00, 8.00). Multiple regression analysis revealed that anxiety, cancer stage, sex, active coping style, and educational level were factors related to body image. These five variables accounted for 40.7% of the total variance in body image. CONCLUSIONS: These findings indicate body image dissatisfaction in surgically treated patients with head and neck cancer. Patients with greater anxiety, a more advanced cancer stage, female sex, fewer active coping strategies, and higher education are more likely to have an inferior body image. Assessment and effective psychosocial interventions are needed initially for patients with head and neck cancer to manage body image concerns.
