ABSTRACT
This study explores the effects of an online mindfulness-based stress reduction intervention on postpandemic era nurses' subjective well-being, job burnout, and psychological adaptation. Previous studies on the psychological adaptability of nurses mainly focused on investigation rather than intervention. Ninety nurses were randomly classified into an intervention or control group. The intervention group received weekly online mindfulness-based stress reduction training for 8 weeks. The Subjective Well-being, Job Burnout, and Psychological Use scales were administered pre- and postintervention. Postintervention, nurses' positive emotions and life satisfaction significantly improved. Nurses' psychological adaptation was significantly higher postintervention than preintervention. The total scores for negative emotion, low personal accomplishment, and job burnout were significantly lower postintervention than preintervention. The scores for positive emotion and life satisfaction in the intervention group were significantly higher than those in the control group, and the scores for low personal accomplishment in the intervention group were significantly lower than those in the control group. Online mindfulness-based stress reduction interventions can improve nurses' subjective well-being, reduce job burnout, and improve their level of psychological adaptability. Moreover, it could promote nurses' ability to communicate mindfully with patients and their families. This intervention could help promote the development of mindfulness in the nursing field.

BACKGROUND: Management of localized or recurrent prostate cancer since the 1990s has been based on risk stratification using clinicopathological variables, including Gleason score, T stage (based on digital rectal exam), and prostate-specific antigen (PSA). In this study a novel prognostic test, the Decipher Prostate Genomic Classifier (GC), was used to stratify risk of prostate cancer progression in a US national database of men with prostate cancer. METHODS: Records of prostate cancer cases from participating SEER (Surveillance, Epidemiology, and End Results) program registries, diagnosed during the period from 2010 through 2018, were linked to records of testing with the GC prognostic test. Multivariable analysis was used to quantify the association between GC scores or risk groups and use of definitive local therapy after diagnosis in the GC biopsy-tested cohort and postoperative radiotherapy in the GC-tested cohort as well as adverse pathological findings after prostatectomy. RESULTS: A total of 572â545 patients were included in the analysis, of whom 8927 patients underwent GC testing. GC biopsy-tested patients were more likely to undergo active active surveillance or watchful waiting than untested patients (odds ratio [OR] =2.21, 95% confidence interval [CI] = 2.04 to 2.38, P < .001). The highest use of active surveillance or watchful waiting was for patients with a low-risk GC classification (41%) compared with those with an intermediate- (27%) or high-risk (11%) GC classification (P < .001). Among National Comprehensive Cancer Network patients with low and favorable-intermediate risk, higher GC risk class was associated with greater use of local therapy (OR = 4.79, 95% CI = 3.51 to 6.55, P < .001). Within this subset of patients who were subsequently treated with prostatectomy, high GC risk was associated with harboring adverse pathological findings (OR = 2.94, 95% CI = 1.38 to 6.27, P = .005). Use of radiation after prostatectomy was statistically significantly associated with higher GC risk groups (OR = 2.69, 95% CI = 1.89 to 3.84). CONCLUSIONS: There is a strong association between use of the biopsy GC test and likelihood of conservative management. Higher genomic classifier scores are associated with higher rates of adverse pathology at time of surgery and greater use of postoperative radiotherapy.In this study the Decipher Prostate Genomic Classifier (GC) was used to analyze a US national database of men with prostate cancer. Use of the GC was associated with conservative management (ie, active surveillance). Among men who had high-risk GC scores and then had surgery, there was a 3-fold higher chance of having worrisome findings in surgical specimens.

Chinese cordyceps, also known as Dong-Chong-Xia-Cao, is widely recognized as a famous precious tonic herb, and used as traditional Chinese medicine for centuries. It is mainly used for regulating the immune system and improving functions of the lung and kidney, with anti-tumor, anti-inflammatory, and anti-diabetic activities. Due to its rarity and preciousness, a few chemical components are isolated and identified. Moreover, most of them are common chemical components and widely distributed in other natural resources, such as nucleosides, sterols, fatty acids, sugar alcohols, and peptides. Therefore, a large number of active substances of Chinese cordyceps is still unclear. During our search for chemical constituents of Chinese cordyceps, a new thiazole alkaloid, cordythiazole A (1), was isolated and identified. Its structure was elucidated by comprehensive spectroscopic analysis and single-crystal X-ray diffraction analysis. This is the first report of the presence of thiazole alkaloid in Chinese cordyceps, which adds a new class of metabolite of Chinese cordyceps. Furthermore, a putative biosynthesis pathway of cordythiazole A was proposed based on possible biogenic precursor, genes, and literatures. In addition, it showed α-glucosidase inhibitory activity with potency close to that of acarbose. The discovery of cordythiazole A with α-glucosidase inhibitory activity adds a new class of potential anti-diabetes ingredient in Chinese cordyceps.

Based on the Janus kinase 2/signal transducer and activator of transcription 3(JAK2/STAT3) signaling pathway, this study investigated the effect of medicated serum of Sparganii Rhizoma(SR) and Curcumae Rhizoma(CR) on the proliferation, apoptosis, migration, and secretion of inflammatory factors of ectopic endometrial stromal cells(ESCs). Specifically, human ESCs were primary-cultured. The effect of different concentration(5%, 10%, 20%) of SR-, CR-, and SR-CR combination-medicated serum, and AG490 solution(50 µmol·L~(-1)) on the proliferation of ESCs was detected by methyl thiazolyl tetrazolium(MTT) assay, and the optimal dose was selected accordingly for further experiment. The cells were classified into normal serum(NS) group, SR group(10%), CR group(10%), combination(CM) group(10%), and AG490 group. The apoptosis level of ESCs was detected by flow cytometry, and the migration ability was examined by wound healing assay. The secretion of interleukin(IL)-1ß, IL-6, and tumor necrosis factor(TNF)-α was determined by enzyme-linked immunosorbent assay(ELISA). The protein levels of cysteinyl aspartate specific protei-nase-3(caspase-3), B-cell lymphoma(Bcl-2), and Bcl-2-associated X protein(Bax) and the levels of phosphorylated(p)-JAK2 and p-STAT3 were detected by Western blot. The results showed that the viability of ESCs cells was lowered in the administration groups compared with the blank serum group(P<0.01), especially the 10% drug-medicated serum, which was selected for further experiment. The 10% SR-medicated serum, 10% CR-medicated serum, and 10% CM-medicated serum could increase the apoptosis rate(P<0.01), up-regulate the protein expression of caspase-3 and Bax in cells(P<0.05 or P<0.01), down-regulate the expression of Bcl-2(P<0.01), decrease the cell migration rate(P<0.05 or P<0.01), and reduce the secretion levels of IL-1ß, IL-6, and TNF-α(P<0.05 or P<0.01), and levels of p-JAK2 and p-STAT3(P<0.05 or P<0.01). Compared with the SR and CR groups, CM group showed low cell viability(P<0.01), high protein expression of caspase-3 and Bax(P<0.05 or P<0.01), and low protein expression of Bcl-2 and p-JAK2(P<0.05). After incubation with CM, the apoptosis rate was higher(P<0.05) and the migration rate was lower(P<0.01) than that of the CR group. The p-STAT3 protein level of CM group was lower than that of the RS group(P<0.05). The mechanism of SR, CR, and the combination underlying the improvement of endometriosis may be that they blocked JAK2/STAT3 signaling pathway, inhibited ESC proliferation, promoted apoptosis, weakened cell migration, and reduced the secretion of inflammatory factors. The effect of the combination was better than that of RS alone and CR alone.

OBJECTIVE: The aim of this study was to explore the association between dietary fatty foods and the risk for bladder cancer. METHODS: Patients newly diagnosed with bladder cancer (n = 113) and 292 controls were recruited. A food frequency questionnaire (FFQ) was used to investigate the food intake within 1 y. Multivariate logistic regression model was used to estimated odds ratio (OR) between different types of fatty food consumption and bladder cancer. RESULTS: The consumption of soybean oil, the largest proportion of cooking oil, in both groups were much higher than the Chinese recommended dietary intake, especially in the control group. Higher intake of red meat was also observed in bladder cancer cases, although lower intakes of marine fish, egg, milk, and dairy products and nuts were observed in controls. After adjusting for potential confounders, the intakes of marine fish and milk and dairy products were negatively correlated with bladder cancer, with the adjusted OR of 0.28 (95% confidence interval [CI], 0.15-0.55) and 0.36 (95% CI, 0.19-0.69). Total nuts were related to a 76% reduction in bladder cancer risk (OR, 0.24; 95% CI, 0.12-0.48). There was clear and positive association between soybean oil and bladder cancer risk with OR of 3.47 (95 % CI, 1.69-7.14). In stratified analyses by sex and smoking status, the relationship was similar for most results, except for milk and dairy products. The negative correlation between milk and dairy products and bladder cancer risk was only found in men; and milk and dairy products and bladder cancer risk were irrelevant by smoking status. No significant association was found between the intakes of other foods and bladder cancer risk. CONCLUSIONS: Intake of nuts and marine fish may be beneficial for the prevention of bladder cancer. The protective effect of milk and dairy products was only found in men with bladder cancer. High soybean oil intake was a risk factor for bladder cancer.

Background: Multidisciplinary team (MDT) meetings are the gold standard of cancer treatment. However, the limited participation of multiple medical experts and the low frequency of MDT meetings reduce the efficiency and coverage rate of MDTs. Herein, we retrospectively report the results of an asynchronous MDT based on a cloud platform (cMDT) to improve the efficiency and coverage rate of MDT meetings for digestive tract cancer. Methods: The participants and cMDT processes associated with digestive tract cancer were discussed using a cloud platform. Software programming and cMDT test runs were subsequently conducted to further improve the software and processing. cMDT for digestive tract cancer was officially launched in June 2019. The doctor response duration, cMDT time, MDT coverage rate, National Comprehensive Cancer Network guidelines compliance rate for patients with stage III rectal cancer, and uniformity rate of medical experts' opinions were collected. Results: The final cMDT software and processes used were determined. Among the 7462 digestive tract cancer patients, 3143 (control group) were diagnosed between March 2016 and February 2019, and 4319 (cMDT group) were diagnosed between June 2019 and May 2022. The average number of doctors participating in each cMDT was 3.26 ± 0.88. The average doctor response time was 27.21 ± 20.40 hours, and the average duration of cMDT was 7.68 ± 1.47 min. The coverage rates were 47.85% (1504/3143) and 79.99% (3455/4319) in the control and cMDT groups, respectively. The National Comprehensive Cancer Network guidelines compliance rates for stage III rectal cancer patients were 68.42% and 90.55% in the control and cMDT groups, respectively. The uniformity rate of medical experts' opinions was 89.75% (3101/3455), and 8.97% (310/3455) of patients needed online discussion through WeChat; only 1.28% (44/3455) of patients needed face-to-face discussion with the cMDT group members. Conclusion: A cMDT can increase the coverage rate of MDTs and the compliance rate with National Comprehensive Cancer Network guidelines for stage III rectal cancer. The uniformity rate of the medical experts' opinions was high in the cMDT group, and it reduced contact between medical experts during the COVID-19 pandemic.
ABSTRACT
Objective: To prospectively study the application effect of traditional Chinese medicine (TCM) anticancer decoction with basic chemotherapy and nursing intervention on oral cancer patients after surgery and the effect on tumor markers and immune function. Methods: Eighty-four postoperative oral cancer patients in our hospital from May 2017 to February 2019 were selected and divided into observation group (42 cases) and control group (42 cases). The control group was treated with basic chemotherapy combined with basic nursing care, and the observation group was treated with TCM anticancer decoction and comprehensive nursing intervention on the basis of the control group. The clinical efficacy, the occurrence of adverse reactions, the satisfaction of nursing care, and the two-year cumulative survival rate of the two groups were compared. The immune function, tumor marker level, VAS score, QoR40 score, and survival quality score of the two groups were compared before and after nursing care. Results: The total clinical treatment efficiency of the observation group (88.10%) was significantly higher than that of the control group (69.05%), and the differences between the two groups in oral cleanliness, aspiration frequency, and oral comfort were statistically significant (P < 0.05). The differences in the occurrence of halitosis, oral fungal infection, leukopenia, gastrointestinal reaction, and fever in the observation group were statistically significant compared with the control group (P < 0.05). The nursing satisfaction rate in the observation group (95.24%) was significantly higher than that in the control group (78.57%). The two-year cumulative survival rate of the observation group (92.86%) was significantly higher than that of the control group (73.81%). After nursing care, CD4+, CD4+/CD8+, VAS scores, QoR40 scores, and quality of survival scores in both groups all increased, and CD8+, CD56+, CEA level, NSE level, and CA19-9 level all decreased (all P < 0.05). Conclusion: The clinical efficacy of TCM anticancer decoction with basic chemotherapy and nursing interventions in the treatment of postoperative oral cancer patients was remarkable, which could significantly improve patients' oral cleanliness and comfort, reduce the frequency of sputum aspiration, improve patients' immunity, reduce tumor marker levels, inhibit tumor activity, improve patients' nursing satisfaction, further improve patients' treatment compliance, reduce patients' pain level, improve patients' survival quality, and prolong patients' survival time with high safety. It could be used as a theoretical basis for subsequent clinical research.

Diabetes mellitus is considered to be a major risk factor for cardiovascular disease, the most common cause of death in diabetes. However, therapeutic strategies for myocardial protection in patients with diabetes are still limited. Cordycepin is a traditional Tibetan medicine with a long history of widespread use, and exerts a wide range of anti-tumor, anti-inflammatory, and anti-oxidative effects. In recent years, although the therapeutic potential of cordycepin has attracted the attention of researchers, it remains unknown whether cordycepin plays a protective role in myocardial ischemia/reperfusion (MI/R) injury in diabetic patients. Here, using a diabetic mouse model, we found that cordycepin protected diabetic hearts from MI/R injury by promoting mitochondrial fusion and Mfn2 expression. Our in vitro results showed that cordycepin enhanced Mfn2-medicated mitochondrial fusion, improved mitochondrial function, and reduced cardiomyocyte apoptosis in high-glucose/high-fat cultured simulated ischemia/reperfusion cardiomyocytes. Furthermore, we found that knockout of Mfn2 significantly blocked the cardioprotective effects of cordycepin in diabetic mice. Finally, an AMPK-dependent pathway was found to upregulate Mfn2 expression upon cordycepin treatment, indicating that cordycepin protected diabetic hearts via AMPK/Mfn2-dependent mitochondrial fusion. Collectively, our study firstly demonstrated that cordycepin could be a potential cardioprotective agent for MI/R injury, and we established a novel mechanism by which upregulated AMPK/Mfn2-dependent mitochondrial fusion contributes to the cardioprotective role of cordycepin.
ABSTRACT
The global seagrass bed ecosystem acts as a natural ecological barrier in the littoral coastal zone. In recent years, this ecosystem has suffered from serious eutrophication and destruction caused by the continuous expansion of aquaculture. However, our understanding of the influence of aquaculture on the bacterial community remains limited. In this study, we used 16S amplicon sequencing to evaluate the impact of aquaculture feed extract solution on the composition and function of bacterial epiphytes and endophyte communities of the core seagrass from the seagrass bed ecosystem in Hainan, Thalassia hemprichii. The feed extract solution was the main factor that significantly affected the bacterial epiphyte and endophyte community structure of seagrass leaves but had no marked effect on alpha diversity was observed. Additionally, the bacterial epiphyte and endophyte community of the T. hemprichii leaves alleviated the effects of organic matter, sulfide, and nutrients caused by aquaculture wastewater. The feed extract solution promoted the proliferation of Bacteroidales, Vibrio, Desulfobulbaceae, Desulfobacteraceae, Pseudoalteromonas, Paludibacter, Marinomonas, and Pseudomonas in the leaves and root of T. hemprichii, which can effectively improve the digestibility of eutrophication. In fact, Desulfobacteraceae and Desulfobulbaceae can reduce sulfate to sulfide and oxidize sulfide to sulfur within seagrass, indicating that the increase in Desulfobulbaceae and Desulfobacteraceae facilitated the accumulation of sulfide with the treatment of feed extract solution, which may be the reason for the degradation of seagrass caused by aquaculture wastewater containing high concentrations of organic pollutants. These results suggest that although seagrass beds can withstand low concentrations of aquaculture pollutants, sulfide emissions should be minimized.

BACKGROUND: Despite recent advances in understanding the complex immunologic dysfunction in the tumor microenvironment (TME), fewer than 20% of patients with head and neck squamous cell carcinoma (HNSCC) respond to immune checkpoint blockade (ICB). Thus, it is important to understand how inhibitory IC receptors maintain the suppressed dysfunctional TME, and to develop more effective combination immunotherapy. This study evaluated the immune-modulating effects of Curcumin, which has well-established anti-cancer and chemopreventive properties, and its long-term safety as a phytochemical drug. METHODS: We carried out the western blot and small interfering RNA (siRNA) transfection assay to evaluate the effects of Curcumin on IC ligands and IC ligands function in HNSCC. Through T-cell cytotoxicity assay and measurements of cytokine secretion, we assessed the effects of combination of Curcumin with programmed death-ligand 1 (PD-L1) Ab on cancer cell killing. Flow cytometry were used to analyze the effects of Curcumin on the expression of programmed cell death protein 1 (PD-1) and T-cell immunoglobulin and mucin-domain3 (TIM-3) on CD4, CD8 and Treg. Immunofluorescence, immunohistochemistry and western blot were used to detecte the cytokine (IFN-γ, Granzyme B), IC receptors (PD-1 and TIM-3) and its ligands (PD-L1, PD-L2, Galectin-9) in xenograft mouse model and 4-nitroquinoline-1-oxide (4-NQO) oral cancer model. RESULTS: We found that Curcumin decreased the expression of IC ligands such as PD-L1, PD-L2, and Galectin-9 in HNSCC, leading to regulation of epithelial-to-mesenchymal transition-associated tumor invasion. Curcumin also effectively restored the ability of CD8+ cytotoxic T cells to lyse cancer cells. To evaluate the effect of Curcumin on the TME further, the 4-NQO oral cancer model was used. Curcumin increased T-cell proliferation, tumor-infiltrating lymphocytes (TILs), and effector cytokines, and decreased the expression of PD-1, TIM-3, suppressive IC receptors and their ligands (PD-L1, PD-L2, and Galectin-9) in the TME, implying reinvigoration of the exhausted CD8+ T cells. In addition, Curcumin inhibited expression of CD4+CD25+FoxP3+ Treg cells as well as PD-1 and TIM-3. CONCLUSIONS: These results show that Curcumin reinvigorates defective T cells via multiple (PD-1 and TIM-3) and multi-level (IC receptors and its ligands) IC axis suppression, thus providing a rationale to combine Curcumin with conventional targeted therapy or ICB as a multi-faceted approach for treating patients with HNSCC.

PURPOSE: Racial/ethnic disparities in breast cancer outcomes may be related to quality of care and reflected in emergency department (ED) visits following primary treatment. We examined racial/ethnic variation in ED visits following breast cancer surgery. METHODS: Using linked data from the California Cancer Registry and California Office of Statewide Health Planning and Development, we identified 151,229 women diagnosed with stage 0-III breast cancer between 2005 and 2013 who received surgical treatment. Differences in odds of having at least one breast cancer-related ED visit within 90 days post-surgery were estimated with logistic regression controlling for clinical and sociodemographic variables. Secondary analyses examined health care-related moderators of disparities. RESULTS: Hispanics and non-Hispanic (NH) Blacks had an increased likelihood of having an ED visit within 90 days of surgery compared to NH Whites [OR = 1.11 (1.04-1.18), p = 0.0016; OR = 1.38 (1.27-1.50), p < 0.0001, respectively]; the likelihood was reduced in Asian/Pacific Islanders [aOR = 0.77 (0.71-0.84), p < 0.0001]. Medicaid and Medicare (vs. commercial insurance) increased the likelihood of ED visit for NH Whites, and to a lesser degree for Hispanics and NH Blacks (p < 0.0001 for interaction). Receipt of surgery at an NCI-designated Comprehensive Cancer Center or at a for-profit (vs. non-profit) hospital was associated with reduced likelihood of ED visits for all groups. CONCLUSION: Racial/ethnic disparities in ED visits following breast cancer surgery persist after controlling for clinical and sociodemographic variables. Improving quality of care following breast cancer surgery could improve outcomes for all groups.

BACKGROUND: It is generally considered that traditional Chinese medicine (TCM) therapy postpones the progression of some chronic kidney diseases (CKDs). Chinese medicine herbs are widely applied in TCM therapy. We aimed to evaluate clinical efficacy and safety of Chinese herbal formula granules in patients with CKD stage 3 through a prospective randomized controlled study. METHODS: A total of 343 participants with CKD stage 3 were recruited from 9 hospitals in Jiangsu Province between April 2014 and October 2016. Participants were randomly assigned to a treatment or control group. Patients in the treatment group orally took Chinese herbal formula granules twice a day, while controls received placebo granules. The duration of intervention was 24 weeks. Primary outcomes were 24-hour proteinuria, serum creatinine, and eGFR, which were measured every 4 weeks. RESULTS: There was no statistical difference in 24-hour proteinuria between the two groups (0.97 ± 1.14 g/d vs. 0.97 ± 1.25 g/d). Patients in the treatment group had significantly lower serum creatinine level (130.78 ± 32.55 µmol/L versus 149.12 ± 41.27 µmol/L) and significantly higher eGFR level (55.74 ± 50.82 ml/min/1.73·m2 versus 44.46 ± 12.60 ml/min/1.73·m2) than those in the control group (P < 0.05). There was no significant difference between two groups in the incidence of adverse events. CONCLUSION: The treatment adopting Chinese herbal formula granules for 24 weeks improved kidney function of patients with CKD stage 3.
ABSTRACT
BACKGROUND: To understand the characteristics of prescriptions and costs in pediatric patients with acute upper respiratory infections (AURI) is important for the regulation of outpatient care and reimbursement policy. This study aims to provide evidence on these issues that was in short supply. METHODS: We conducted a retrospective cross-sectional study based on data from National Engineering Laboratory of Application Technology in Medical Big Data. All outpatient pediatric patients aged 0-14 years with an uncomplicated AURI from 1 January 2015 to 31 December 2017 in 138 hospitals across the country were included. We reported characteristics of patients, the average number of medications prescribed per encounter, the categories of medication used and their percentages, the cost per visit and prescription costs of drugs. For these measurements, discrepancies among diverse groups of age, regions, insurance types, and AURI categories were compared. Kruskal-Wallis nonparametric test and Student-Newman-Keuls test were performed to identify differences among subgroups. A multinomial logistic regression was conducted to examine the independent effects of those factors on the prescribing behavior. RESULTS: A total of 1,002,687 clinical records with 2,682,118 prescriptions were collected and analyzed. The average number of drugs prescribed per encounter was 2.8. The most frequently prescribed medication was Chinese traditional patent medicines (CTPM) (36.5% of overall prescriptions) followed by antibiotics (18.1%). It showed a preference of CPTM over conventional medicines. The median cost per visit was 17.91 USD. The median drug cost per visit was 13.84 USD. The expenditures of antibiotics and CTPM per visit (6.05 USD and 5.87 USD) were among the three highest categories of drugs. The percentage of out-of-pocket patients reached 65.9%. Disparities were showed among subgroups of different ages, regions, and insurance types. CONCLUSIONS: The high volume of CPTM usage is the typical feature in outpatient care of AURI pediatric patients in China. The rational and cost-effective use of CPTM and antibiotics still faces challenges. The reimbursement for child AURI cases needs to be enhanced.

PURPOSE: We assessed the optimal time for intact parathyroid hormone (iPTH) measurement for early detection of post-total thyroidectomy (TT) hypocalcemia in patients with papillary thyroid carcinoma (PTC). METHODS: In this single-center prospective cohort study, 143 patients who underwent TT with central neck dissection with or without lateral neck dissection for PTC were included. Biochemical profiles including iPTH, corrected total calcium, and ionized calcium within 24 h after surgery were analyzed. RESULTS: The 4-h postoperative iPTH was the most reliable predictor of post-TT transient or permanent hypoparathyroidism (cutoff for hypocalcemia was 3.75 pg/mL, AUC = 0.885, P < 0.001, sensitivity 81.6%, specificity 86.0%; cutoff for permanent hypocalcemia was 2.48 pg/mL, AUC = 0.819, P < 0.001, sensitivity 100%, specificity 57.8% calculated using ROC curves). CONCLUSIONS: The 4-h postoperative iPTH can most accurately predict hypoparathyroidism after TT with central neck dissection to treat PTC and facilitate the early discharge of low-risk postoperative hypoparathyroidism patients and decrease unnecessary overnight observation and calcium supplementation.

Problems associated with water eutrophication due to high phosphorus concentrations and related environmentally safe solutions have attracted wide attention. A novel bis(diallyl alkyl tertiary ammonium salt) polymer, particularly poly(N1,N1,N6,N6-tetraallylhexane-1,6-diammonium dichloride) (PTAHDADC), was synthesized and characterized by Fourier transform infrared spectroscopy, nuclear magnetic resonance, scanning electron microscopy, mercury intrusion method, and thermogravimetric analysis. The adsorption characteristics in phosphorus were evaluated in dilute solution, and the recycling properties of PTAHDADC were investigated. Results showed that PTAHDADC possessed macropores with a size distribution ranging from 30 to 130⯵m concentrating at 63⯵m in diameter and had 46.52% of porosity, excellent thermal stability below 530K, and insolubility. PTAHDADC could effectively remove phosphorus at pHâ¯=â¯7-11 and had a removal efficiency exceeding 98.4% at pHâ¯=â¯10-11. The adsorption equilibrium data of PTAHDADC for phosphorus accorded well with the Langmuir and pseudo-second-order kinetic models. Maximum adsorption capacity was 52.82â¯mg/g at 293â¯K. PTAHDADC adsorbed phosphorus rapidly and reached equilibrium within 90â¯min. Calculated activation energy Ea was 15.18â¯kJ/mol. PTAHDADC presented an excellent recyclability with only 8.23% loss of removal efficiency after five adsorption-desorption cycles. The morphology and structure of PTAHDADC slightly changed as evidenced by the pre- and post-adsorption of phosphorus, but the process was accompanied by the partial deprotonation of the (-CH2)3NH+ group of PTAHDADC. The adsorption was a spontaneous exothermic process driven by entropy through physisorption, electrostatic attraction, and ion exchange. Survey results showed that PTAHDADC was a highly efficient and fast-adsorbing phosphorus-removal material prospective in treating wastewater.

Anaerobic oxidation of methane (AOM) is a common biochemical process in the ocean and it plays an important role in global climate change, elemental circulation, and atmospheric evolution over geological time. In this paper, we analyzed of δ34S, Fe, Mn, Ca/Ti, and Sr/Ti ratios, and the date of carbon and sulfur from the site SH3 of Shenhu area. Result showed that (1) 0-6 mbsf (meter blow the sea floor) was mainly affected by OSR (anaerobic oxidation of organic matters) and 7-15 mbsf was a paleo-SMTZ (sulfate-methane transition zone) position. The modern SMTZ was mainly distributed at 19-25 mbsf. The barium sulfate precipitation above the modern SMTZ indicating that the current methane leakage was stable and lasted longer during geological history. (2) By studying the change of magnetic and the different carbonate minerals, results showed that there were two AOM stages. During the early stage, Fe2+ were mainly produced by sulfide abiotic reductive dissolution. During the later stage, Fe2+ were mainly produced by the metal-AOM. (3) Study of the mineral characteristics of the paleo-SMTZ and the modern SMTZ showed that the modern SMTZ carbonate minerals were mainly low-Mg calcite and aragonite, while the paleo-SMTZ carbon minerals were mainly high Mg minerals. The reason for this difference is that the modern SMTZ layer was only experienced the first stage of anaerobic oxidation of methane. In the paleo-SMTZ layer, it has experienced two stage of anaerobic oxidation of methane. During the last stage of metal-AOM, the low Mg carbonate minerals were converted into high Mg carbonate minerals. This research confirms the presence of metal-driven methane anaerobic oxidation at the bottom of sulfate-driven methane anaerobic oxidation and during the metal-driven methane anaerobic oxidation, methane and metal oxides or hydroxides would couple to convert the in situ metal oxides or hydroxides into metal ions, meanwhile the phosphorus adsorbed on the surface of the metal oxides is released into adjacent pore water, and convert to new P-bearing minerals under suitable conditions.

ETHNOPHARMACOLOGICAL RELEVANCE: As one of the most common female malignant tumors mainly infected by human papillomavirus (HPV) worldwide, cervical cancer is widely distributed in about 90% developing countries. An in-hospital preparation derived from a traditional Chinese herbal formula, Youdujing (YDJ), has been developed and clinically used for more than 20 years in our hospital for treating multiple diseases caused by HPV infection, such as cervical precancerous lesions, recurrent condyloma acuminata, fla t warts, etc. However, few investigations on the effect and mechanism of YDJ extract on treating and preventing HPV infection induced cervical cancer have been reported. AIM OF THE STUDY: Previous reports showed that YDJ extract is effective in triggering human cervical cancer cells (ectocervical Ect1/E6E7) death in a necrotic manner. Herein, we aim to investigate the anti-proliferation effects and potential mechanisms of YDJ extract in inducing necroptosis in ectocervical Ect1/E6E7 cells. MATERIALS AND METHODS: The high-performance liquid chromatography (HPLC) fingerprint method was firstly used for better quality control of the chemical components in YDJ extract. MTT assay and flow cytometer were applied for evaluating cytotoxicity and necroptosis induced by YDJ extract in ectocervical Ect1/E6E7 cells. Besides, Western blotting, receptor-interacting protein serine-threonine kinase 1 (RIP1) inhibitor (necrostatin-1), and RIP1 shRNA and pCDNA transfection assays were employed for investigation on the underlying mechanisms and validation the role of RIP1 in YDJ extract induced necroptosis. RESULTS: YDJ extract induced necroptosis in ectocervical Ect1/E6E7 cells both in time- and concentration-dependent manners, without affecting activation of caspases and elevation of intracellular reactive oxygen species (ROS) level. Moreover, a selective increasing in RIP1expression was observed in YDJ extract treated ectocervical Ect1/E6E7 cells. The induction effect of necroptosis by YDJ extract was partially blocked by the addition of RIP1 inhibitor (necrostatin-1). Co-immunoprecipitation assay demonstrated that the treatment of YDJ extract in ectocervical Ect1/E6E7 cells promoted the combination of RIP1 with RIP3 and MLKL to form necrosome, which facilitates the process of necroptosis. CONCLUSIONS: Taken together, YDJ preparation displays an effective ability of inducing necroptosis in cervical cancer cells through activation of RIP1 kinase. However, although the treatment efficacy and potential mechanisms of YDJ extract in vivo remain unclear and need further investigation, it is believed that YDJ extract has the great potential to be used as a starting point to develop more potent agent for treating or preventing cervical cancer and other proliferative diseases.

Neuroinflammation has been suggested to be involved in the pathogenesis of postoperative cognitive dysfunction (POCD). Electroacupuncture (EA) is an irreplaceable method in traditional Chinese medicine that is used for treating neurodegenerative diseases in clinical and experimental studies. The aim of this study was to examine whether EA improves cognitive dysfunction caused by surgery and to investigate the pathological mechanism of TLR2 and TLR4 in the hippocampus of aged rats. A rat model of POCD was established and treated with EA or minocycline. Both EA- and minocycline-treated rats performed significantly better than untreated operated rats in spatial memory tasks of the Morris water maze (MWM) test, spending comparatively greater amounts of time in the target zone during the probe test. Additionally, decreased levels of proinflammatory cytokines (IL-1ß, IL-6, TNF-α, and HMGB1) and decreased TLR2 and TLR4 protein expression in the hippocampus of EA- and minocycline-treated rats were detected. Our data suggested that EA treatment alleviated the cognition performance deficit and neuroinflammation in aged rats following surgery, which may be mediated by inhibiting the expression of hippocampal neuroinflammatory cytokines through the microglia/TLR2/4 pathway.
ABSTRACT
AIM OF THIS STUDY: Chemotherapy-induced peripheral neuropathy (CIPN) is a major complication of cancer patients with chemotherapy. Although many interventions have been evaluated in previous studies, findings are controversial. The aim of this meta-analysis is to assess the efficacy of vitamin E supplementation in preventing CIPN. MATERIAL AND METHODS: The electronic databases MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials were systematically searched from their inception to December 31, 2013 to identify relevant randomised controlled trials. Two reviewers independently scanned and extracted the data of included studies. Review Manager 5.2 was used to analyse data. RESULTS: Six articles involving 353 patients were included in meta-analysis. The results showed that vitamin E supplementation did not appear to significantly decrease the incidence of CIPN (relative risk (RR), 0.55; 95% confidence interval (CI), 0.29 to 1.05; p = 0.07), with significant heterogeneity (I(2) = 77%). However, Vitamin E supplementation can significantly prevent cisplatin associated neurotoxicity (RR, 0.31; 95%CI, 0.17 to 0.58; p = 0.0002), with no heterogeneity (I(2) = 0%). CONCLUSIONS: Vitamin E administration dose not decrease the incidence of CIPN. However, additional randomised controlled trials using large samples are needed to confirm the role of vitamin E supplementation.
ABSTRACT
OBJECTIVE: To observe the clinical effect of Ziyin Huoxue Granule (ZHG) combined glucocorticoids and antibiotics in treatment of radiation pneumonitis. METHODS: Totally 70 radiation pneumonitis patients were assigned to the treatment group and the control group according to random digit table, 35 in each group. All patients received glucocorticoids and antibiotics. Patients in the treatment group additionally took ZHG, one dose per day for 4 successive weeks. Watters clinical-radiologic-physiologic (CRP) score, Karnofsky Performance Status Scale (KPS) , and acute radiation injury classification [set by Radiation Therapy Oncology Group (RTOG)] were observed in the two groups before and after treatment. The application time for antibiotics and glucocorticoids was compared between the two groups. RESULTS: All patients completed this trial, and nobody dropped out or died. There was no statistical difference in Watters-CRP scores, KPS, or RTOG between the two groups before treatment (P > 0.05). Compared with before treatment in the same group, RTOG classification was obviously improved in the two groups (P < 0.05). Compared with the control group, Watters-CRP scores decreased, KPS increased, the application time for antibiotics and glucocorticoids was reduced (P < 0.05). The efficacy of RTOG classification was better in the treatment group than in the control group, but with no statistical difference between the two groups (P > 0.05). CONCLUSION: ZHG combined glucocorticoids and antibiotics was superior in treating radiation pneumonitis to using glucocorticoids or antibiotics alone in elevating Watters-CRP scores, shortening the application time for glucocorticoids and antibiotics, and improving patients' physical conditions.
