Liver failure （LF） is a great trouble to the majority of patients due to its severe onset， many complications， difficult treatment， poor prognosis and other characteristics. This disease is liver injury caused by infection， hepatotoxic substances， autoimmunity， circulation disorders and other factors. It is a group of common clinical symptoms mainly manifested by coagulation disorders， jaundice， hepatic encephalopathy， ascites， and so on. In traditional Chinese medicine， it falls under the categories of "tympanites"， "jaundice" and other diseases. At present， the research progress of Western medicine in the treatment of LF is slow， and its clinical application effect is still not ideal. In contrast， traditional Chinese medicine has a long history in the treatment of this disease， with over thousands of years of clinical practice and verification. It is characterized by exact efficacy and fewer side effects. The pathological mechanism of LF is extremely complex， involves a variety of signaling pathways， and is mainly related to inflammation， oxidative stress， liver fibrosis， cell apoptosis and other processes. In recent years， many studies have shown that traditional Chinese medicine can intervene in the occurrence and development of LF by mediating relevant signaling pathways in vivo， but there is still a lack of relevant summary. Therefore， this review summarized several signaling pathways related to the intervention of traditional Chinese medicine in LF by referring to and sorting out relevant literature worldwide， including nuclear factor kappa B （NF-κB）， mitogen-activated protein kinase （MAPK）， phosphatidylin-ositol-3-kinase/protein kinase B （PI3K/Akt）， transforming growth factor-β/ drosophila mothers against decapentaplegic proteins （TGF-β/Smads）， and nuclear factor erythroid 2-related factor 2/heme oxygenase-1 （Nrf2/HO-1）， and elaborated the specific mechanism of their intervention in LF. This paper aims to provide practical and effective pathways and corresponding mechanisms for the treatment of LF by traditional Chinese medicine， and to provide new ideas and a theoretical basis for the clinical treatment of LF and further scientific research.

In order to ensure the safety of VA-ECMO treatment and reduce the incidence of related complications, healthcare professionals should carefully select and apply evidence according to the clinical context and patients′ wishes.

" Behavior determines health" is the theoretical and practical basis of behavioral medicine. Maladpative lifestyle is not only an important risk factor for many non-communicable diseases, but also an important influencing factor for recurrence and prognosis of emotional disorders. More and more meta-analyses have confirmed the role of behavioral lifestyle in the treatment and prevention of emotional disorders such as depression. Some authoritative treatment guidelines now recommend lifestyle changes as one of the firstline treatment recommendations and given some specific modalities in detail. There is relatively less evidence for treatment of anxiety disorders and bipolar disorder, but there are several well-designed and high-quality studies that confirm the therapeutic and preventive role of lifestyles, particularly circadian rhythms, life regurality and exercises, as part of routine management measures for maintaining stable mood and alleviating anxiety symptoms.

This study was designed to investigate the effect of silencing microtubule-affinity regulating kinase 4(MARK4)on the apoptosis,inflammatory cytokine release and intestinal barrier protein expression of FHC cells in a lipopolysaccharide(LPS)-induced ulcerative colitis(UC)model,and the underlying molecular mechanisms.Western blot analysis was used to measure the expression levels of MARK4 and apoptosis-related factors including Caspase-1,NLRP3,and GSDMD in colon tissues from both UC patients and healthy individuals,as well as in LPS-induced FHC cell inflammation model.FHC cells was transfected with shRNA to silence MARK4.In control(normal FHC cells),LPS(LPS-stimulated FHC cells),and MARK4-silenced+LPS(shRNA-and LPS-treated FHC cells)groups,the expression levels of Caspase-1,NLRP3,GSDMD,intestinal barrier proteins,and NF-κB pathway-related proteins were assessed by Western blotting.ELISA and RT-qPCR were used to measure the expression levels of inflammatory cytokines IL-1β,IL-6,and TNF-α;flow cytometry was utilized to assess apoptosis.Data showed that both in UC patient colon tissues and the in vitro LPS-induced FHC cell UC inflammation model,there was a significant increase in the expression of MARK4 and apoptosis-related proteins including NLRP3,Caspase-1,and GSDMD.Silencing MARK4 inhibited the expression of these apoptosis-related proteins and downregulated the inflammatory cytokines IL-1β,IL-6,and TNF-α in LPS-induced FHC cells.Silencing MARK4 also reduced apoptosis,increased the expression of intestinal barrier proteins ZO-1,Occludin,and upregulated Claudin2.Gene Set Enrichment Analysis(GSEA)indicated a positive correlation between MARK4 and the NF-κB signaling pathway.Furthermore,silencing of MARK4 inhibited the expression levels of p-P65 and p-IKKα in the NF-κB pathway.In conclusion,MARK4 is significantly upregulated in UC tissues and cells.Silencing MARK4 inhibits the activation of the NF-κB signaling pathway,thereby inhibiting the apoptosis and inflammatory factor expression of UC cells.Thus,MARK4 could be a potential therapeutic target for UC patients.

{L-End}Objective To analyze the effects of night shift work and overweight/obesity on blood pressure of workers in chemical fiber industry. {L-End}Methods A total of 1 004 workers of a chemical fiber factory were selected as the study subjects using convenient sampling method, and their blood pressure and body mass index were measured. Multiple linear regression model was used to analyze the relationship between night shift work and blood pressure, and multiple logistic regression was used to assess the independent impact and combined impact of night shifts and overweight/obesity on the risk of hypertension. {L-End}Results Compared with the non-night shift workers, the prevalence of hypertension in night shift workers was increased (5.3% vs 13.0%, P<0.05), with elevated systolic and diastolic blood pressure (both P<0.05). The results of multiple linear regression analysis showed that the systolic blood pressure and diastolic blood pressure of the night shift workers were higher than those of the non-night shift workers (both P<0.05), and the systolic blood pressure and diastolic blood pressure of overweight/obesity workers were higher than those of non-overweight/obesity workers (both P<0.01). The results of multiple logistic regression analysis showed that the risk of hypertension in night shift workers and overweight/obesity workers was higher than that in non-night shift workers and non-overweight/obesity workers [odds ratio (OR) and 95% confidence interval (CI) were 2.49 (1.04-5.99) and 2.65 (1.77-3.95), both P<0.05]. Night shift work and overweight/obesity showed a synergistic effect on blood pressure of workers. Compared to non-overweight/obesity non-night shift workers, overweight/obesity night shift workers had a higher risk of hypertension (OR=4.93, 95%CI: 1.70-14.29, P<0.01). {L-End}Conclusion Night shift work could lead to elevated blood pressure in workers in the chemical fiber industry, which is a potential risk factor for hypertension. The synergistic effect of night shift work and overweight/obesity may contribute to the increased risk of hypertension.

Objective : To investigate the status of occupational stress and analyze its influencing factors among frontline employees working in a chemical fiber manufacturing enterprise, so as to provide insights into the development of occupational stress interventions. Methods : The frontline employees working in a chemical fiber manufacturing enterprise were selected as the study subjects using a cluster sampling method in October 2018. The status of occupational stress was investigated using the Chinese version of the effort-reward imbalance ( ERI ) questionnaire. The influencing factors for occupational stress were identified using a multivariable logistic regression model. Results : A total of 1 780 questionnaires were sent out, and 1 115 valid ones ( 62.64% ) were recovered. Among the 1 115 respondents, there were 427 men ( 38.30% ) and 688 women ( 61.70% ), and 71.22% were at ages of 21 to 39 years. There were 561 respondents with < 1 year of service ( 50.31% ), and the longest length of service was 11 years. In addition, there were 1 069 respondents ( 95.87% ) exposed to high noise, and 346 respondents ( 31.03% ) were diagnosed at a high occupational-stress state and 769 ( 68.97% ) at a low state. Multivariable logistic regression analysis identified 5 years or longer of service ( OR=1.540, 95%CI: 1.057-2.245 ) and exposure to high noise ( OR=1.917, 95%CI: 1.004-3.659 ) as risk factors for occupational stress among frontline employees in the chemical fiber manufacturing enterprise. Conclusions There are 31.03% of frontline employees at a high occupational-stress state in the chemical fiber manufacturing enterprise, and a high occupational-stress state is associated with exposure to high noise and 5 years or longer of service.

Objective:To investigate the clinical application value of serum carcinoembryonic antigen (CEA) level in predicting lymph node metastasis of resectable medullary thyroid carcinoma (MTC) .Methods:140 patients of resectable MTC from Zhejiang Cancer Hospital and Hangzhou First People’s Hospital from Jan. 2009 to Feb. 2019 were included. The relationship of serum CEA and lymphatic metastasis was retrospectively analyzed in 140 patients of resectable MTC, and the clinical significance of serum CEA for predicting total lymph node, central lymph node, lateral lymph node and upper mediastinal lymph node metastasis was also evaluated.Results:The positive rate of serum CEA in resectable MTC was 77.14%. The expression level of serum CEA in resectable MTC with lymph node metastasis was significantly higher than those without lymph node metastasis ( P<0.001) . Spearman correlation analysis further indicated that the level of serum CEA expression was positively correlated with the number of lymph node metastases of resectable MTC patients ( P<0.001) . The area under curve of predicting lymphatic metastasis of total lymph node, central lymph node, lateral lymph node and upper mediastinum was 0.773, 0.768, 0.827 and 0.847. When the cut-off value of serum CEA was 6.58, 11.43, 15.74 and 30.45 ng/ml, respectively, the sensitivity of serum CEA to predict total, central, lateral neck and upper mediastinal lymph node metastasis was 88.46%, 81.43%, 85.00%, 95.00%, and the specificity was 56.45%, 60.00%, 71.25%, and 69.17%, respectively. Conclusion:Serum CEA has a high positive expression rate in resectable MTC, and its expression level has important clinical significance in evaluation of lymphatic metastasis.

Objective:To evaluate the efficacy of somatosensory evoked potential (SEP) monitoring for prevention of deep venous thrombosis (DVT) in lower extremity of patients undergoing spinal surgery.Methods:A total of 120 patients of both sexes, aged 40-70 yr, of American Society of Anesthesiologists physical status ⅠorⅡ, without impairment of coagulation function, undergoing posterior lumbar interbody fusion, were selected and divided into 3 groups ( n=40 each) using the random number table method and envelope method: basic preventive measure group (group A), compression stocking group (group B) and SEP monitoring group (group C). In group B, elastic stockings were worn at 1 h before surgery.SEP monitoring was performed during surgery, and the intensity of current stimulation was 25 mA in group C. The flow velocity of popliteal vein in both lower extremities was measured using color Doppler ultrasound apparatus during surgery.Venous blood samples were taken to measure plasma D-dimer concentrations at 1 day before surgery, at the end of surgery and at 24 h after surgery.The DVT developed in lower extremities was diagnosed by ultrasound method during surgery and within 24 h after surgery. Results:Compared with A and B groups, the blood flow velocity of popliteal vein was significantly increased, and the plasma D-dimer concentration and incidence of DVT developed in lower extremity during surgery were decreased in group C ( P<0.05). Conclusion:SEP monitoring can effectively prevent the occurrence of DVT in lower extremity while it is used as an electrophysiological monitoring of the spinal cord in patients undergoing spinal surgery.

" Health China: 2030" is an important program and great work of the Chinese health care development in the future. Because of the many none-communication diseases (NCDs) in China are associated with some behavioral risk factors (e.g. tobacco and alcohol use, physical inactivity, and unhealthy diet, etc.), the behavioral intervention focused on these behavioral risks and unhealthy life habits should be main work for behavioral medicine. " Health is depended on the behavioral style" is always the topic of behavioral medicine promotion in China in the past, now and the future. The author recommends that the following behavioral risks control and intervention should be concerned in practice: sleep, physical inactivity and high body mass index, tobacco use and harmful use of alcohol, unhealthy diet, depression and anxiety. If these behavioral risks and unhealthy life habits would be effective intervention or controlled, the sustainable development goal index and the healthy life expectancy in China will be improved further.

In recent years,some critical investigations have compelled us to improve the early recog-nition rate and treatment rate of mental disorders. Unhealthy lifestyles have become major influencing factors of health and longevity. With the effort of all practitioners,behavioral medicine has thrived in the latest dec-ades. In the future,we should put more energy in education,investigation and propagation. In short,emo-tion,behavior and health are the invariable themes of behavioral medicine.
