At present,the network media reports of Chinese medical disputes appeared blowout growth,and also brought the loss of propriety,the loss of balance,the loss of justice and other ethical issues while it played the role of public opinion supervision in the medical disputes.In view of these,from the concept definition of ethics anomie in network media report of medical disputes,this paper analyzed and interpreted the ethics anomie in network media report of medical disputes,pointed out existing problems and further put forward creating the network media professional ethics norms,establishing a social supervisory system which integrates self-discipline and heteronomy,building a doctor-patient docking platform and other perfecting countermeasures.

Objective To investigate the dyadic coping experience of patients undergoing cancer surgery and their spouses.Methods Sixteen cancer patients who were initially diagnosed with cancer and underwent cancer surgery in a general hospital in Henan province as well as and their spouses were selected as the study subjects by objective sampling method.All the patients and their spouses were included in the postoperative follow-up for dyadic coping experiences though a 3 months interview.The acquired data were summarised and analysed by Colaizzi's phenomenological method to identify relevant themes.Results A total of eight themes were identified,including three themes over the phase of confirmed diagnosis,strong stress response,coping with stress alone and consistent attitude towards seeking medical treatment;two themes over the perioperative phase,lack of coping ability and change in relationship;and three themes over the phase of home recovery,lack of disease information,poor communication skills and post-trauma growth of both patient and spouse.Conclusions The dyadic coping experience of patients who undergo cancer surgery and their spouses varies with the stages across the treatment.Therefore,medical staff should offer targeted nursing care according to the dyadic coping experience at different stages,hence to improve the physical and mental health of the cancer patients and their spouses.

Objective: This study aimed to evaluate the role of preoperative two-dimensional (2D) shear wave elastography (SWE) in assessing the stages of liver fibrosis in patients with suspected biliary atresia (BA) and compared its diagnostic performance with those of serum fibrosis biomarkers. Materials and Methods: This study was approved by the ethical committee, and written informed parental consent was obtained. Two hundred and sixteen patients were prospectively enrolled between January 2012 and October 2018. The 2D SWE measurements of 69 patients have been previously reported. 2D SWE measurements, serum fibrosis biomarkers, including fibrotic markers and biochemical test results, and liver histology parameters were obtained. 2D SWE values, serum biomarkers including, aspartate aminotransferase to platelet ratio index (APRi), and other serum fibrotic markers were correlated with the stages of liver fibrosis by METAVIR. Receiver operating characteristic (ROC) curves and area under the ROC (AUROC) curve analyses were used. Results: The correlation coefficient of 2D SWE value in correlation with the stages of liver fibrosis was 0.789 (p < 0.001). The cut-off values of 2D SWE were calculated as 9.1 kPa for F1, 11.6 kPa for F2, 13.0 kPa for F3, and 15.7 kPa for F4. The AUROCs of 2D SWE in the determination of the stages of liver fibrosis ranged from 0.869 to 0.941. The sensitivity and negative predictive value of 2D SWE in the diagnosis of ≥ F3 was 93.4% and 96.0%, respectively. The diagnostic performance of 2D SWE was superior to that of APRi and other serum fibrotic markers in predicting severe fibrosis and cirrhosis (all p < 0.005) and other serum biomarkers. Multivariate analysis showed that the 2D SWE value was the only statistically significant parameter for predicting liver fibrosis. Conclusion 2D SWE is a more effective non-invasive tool for predicting the stage of liver fibrosis in patients with suspected BA, compared with serum fibrosis biomarkers.

Objective:To explore the influence of chronic rhinitis on depressive symptoms of college freshmen and the mediating effect of avoidant personality.Methods:A cluster sampling method was used to survey 8 079 college freshmen from April 2018 to October 2018 using the Beck depression inventory and the avoidant personality diagnosis questionnaire based on DSM-Ⅳ.SPSS 25.0 software was used for descriptive statistics and Spearman correlation analysis, and the macro program PROCESS version 3.3 was used for the mediating effect.Results:(1) The detection rates of chronic rhinitis, avoidant personality and depressive symptoms were 22.90% (1 850/8 079), 19.22% (1 553/8 079) and 6.28% (507/8 079). The scores for avoidant personality disorder and depressive symptoms were 1.00 (0, 3.00) and 1.00 (0, 4.00), respectively. (2) The chronic rhinitis, avoidant personality and depressive symptoms were positively correlated ( rchronic rhinitis-avoidant personality=0.094, rchronic rhinitis-depressive symptoms=0.095, ravoidant personality-depressive symptoms=0.416, all P<0.001). (3) Chronic rhinitis could positively predict depressive symptoms ( β=1.113, P<0.001). (4) Avoidant personality played a mediating role between chronic rhinitis and depressive symptoms ( β=1.094, P<0.001), and accounted for 44.92%(0.500/1.113) of the total effect. Conclusion:Chronic rhinitis directly affect the depressive symptoms of college freshmen, and indirectly affect the depressive symptoms of college freshmen through the mediating role of avoidant personality.

Objective:To evaluate the effects of remazolam and propofol on the hemodynamics during induction of anaesthesia in elderly patients using the area under curve (AUC) method.Methods:Eighty elderly patients of either sex, aged 65-75 yr, with body mass index of 20-28 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, scheduled for elective non-cardiac surgery, were divided into 2 groups ( n=40 each) by using a random number table method: remazolam group (R group) and propofol group (P group). Remazolam 1 mg/ml or propofol 10 mg/ml was slowly and intravenously injected through titration to achieve loss of responsiveness to verbal command. The accumulative areas under the curve below (AUC MAP-) or above (AUC MAP+ ) baseline mean arterial pressure and under the curve below or above 10% of baseline heart rate at the same time (AUC HR-, AUC HR+ ) were calculated within the first 10 min after administration of propofol or remazolam. The use of vasoactive drugs and injection pain were recorded during this period. The intraoperative awareness during the 24-h follow-up after surgery and development of cardiovascular complications, cerebral infarction and oliguria or anuria within 30 days after surgery were recorded. Results:Compared with R group, AUC MAP- was significantly enlarged (the mean difference 59.375 mmHg·min, 95% confidence interval 26.763-91.987 mmHg·min), AUC HR- was enlarged ( P<0.05), and no significant change was found in AUC MAP+, AUC HR+, requirement for vasoactive drugs, frequency of vasoactive drugs, and postoperative complications in P group ( P>0.05). No injection pain or intraoperative awareness was found in two groups. Conclusions:Remazolam is superior to propofol in maintaining hemodynamic stability during anesthesia induction in elderly patients.

Objective:To investigate the predictive value of serum D-dimer combined with myocardial injury markers on admission for early identification of high-risk patients with acute myocarditis.Methods:Patients hospitalized for acute myocarditis in China-Japan Friendship Hospital were retrospectively enrolled from 2010 to 2021. Patients were divided into the high D-dimer level group and low D-dimer level group according to the median value of D-dimer measured by immunoturbidimetry within 24 h of admission. In-hospital adverse events were defined as death, cardiogenic shock, malignant ventricular arrhythmia and new-onset heart failure. Multivariate logistic analysis was used to explore the independent predictors of in-hospital adverse events, and receiver operating characteristic curve was used to evaluate the predictive value.Results:A total of 106 patients were analyzed, including 52 high level D-dimer patients and 54 low level D-dimer patients, with an average age of (36±16) years, and 62.3% were male. Compared with the low D-dimer level group, patients in the high D-dimer level group had lower mean systolic blood pressure [(114±21) mmHg vs. (121±14) mmHg] and diastolic blood pressure [(71±13) mmHg vs. (76±10) mmHg], higher heart rate [(97±26) beats/min vs. (79±15) beats/min], higher C-reactive protein levels [6.82 (1.61, 20.05) mg/dL vs. 1.30 (0.13, 8.93) mg/dL] and creatinine levels [86.95 (67.63, 117.83) μmol/L vs. 68.80 (60.18, 81.93) μmol/L] on admission. The proportion of patients having QRS interval >120 ms on electrocardiogram was higher in high D-dimer level group (25.0% vs. 7.4%). There was no significant difference in patients with positive myocardial injury biomarkers between the two groups. The incidence of in-hospital adverse events was higher in the high D-dimer level group (67.3% vs. 22.2%, P<0.001). Multivariate logistic analysis showed that serum D-dimer levels and elevated myocardial injury markers on admission were independently associated with in-hospital adverse events. The area under the curve (AUC) of elevated serum D-dimer level on admission for predicting in-hospital adverse events was 0.781 (95% CI: 0.690-0.873), the sensitivity was 74.5%, and the specificity was 71.2%. When combined with positive cardiac biomarkers, the AUC was 0.831 (95% CI: 0.752-0.910) with a sensitivity of 80.9% and a specificity of 78.0%. Conclusions:Elevated D-dimer level on admission can predict the risk of in-hospital adverse events in patients with acute myocarditis. The combination of cardiac injury biomarkers can improve the predictive value.

Curcuminoids are rare diketone compounds in plants and can be found in the rhizome of Curcuma longa as well as other Zingiberaceae and Araceae. Curcuminoids have been widely used in food and medical area owing to the yellow colors, as well as the antioxidant and many other pharmacological activities. Curcuminoids are a mixture of compounds containing curcumin, demethoxycurcumin and bisdemethoxycurcumin, which have distinct benzene ring substituents. Currently, curcuminoids are exclusively produced through plant extraction, which do not satisfy the meeting of the market demand. Empowered with new synthetic biology tools and metabolic engineering strategies, there is renewed interest in production of curcuminoids using microorganisms. Heterologous production of curcuminoids has been achieved using Escherichia coli, Yarrowia lipolytica, Pseudomonas putida and Aspergillus oryzae via engineering of curcuminoids biosynthesis pathway. In this review, we first describe the biological activities and various applications of curcuminoids. Next, we summarize the biosynthetic pathway of curcuminoids in Curcuma longa and discuss the catalytic mechanisms of curcumin synthases. Then, we thoroughly explore recent advances in the use of distinct microorganisms for the production of curcuminoids with a special focus on metabolic engineering strategies. Finally, we prospect the microbial production of curcuminoids by highlighting some promising techniques and approaches.
