The small-molecule alkaloid halofuginone (HF) is obtained from febrifugine. Recent studies on HF have aroused widespread attention owing to its universal range of noteworthy biological activities and therapeutic functions, which range from parasite infections and fibrosis to autoimmune diseases. In particular, HF is believed to play an excellent anticancer role by suppressing the proliferation, adhesion, metastasis, and invasion of cancers. This review supports the goal of demonstrating various anticancer effects and molecular mechanisms of HF. In the studies covered in this review, the anticancer molecular mechanisms of HF mainly included transforming growth factor-β (TGF-β)/Smad-3/nuclear factor erythroid 2-related factor 2 (Nrf2), serine/threonine kinase proteins (Akt)/mechanistic target of rapamycin complex 1(mTORC1)/wingless/integrated (Wnt)/β-catenin, the exosomal microRNA-31 (miR-31)/histone deacetylase 2 (HDAC2) signaling pathway, and the interaction of the extracellular matrix (ECM) and immune cells. Notably, HF, as a novel type of adenosine triphosphate (ATP)-dependent inhibitor that is often combined with prolyl transfer RNA synthetase (ProRS) and amino acid starvation therapy (AAS) to suppress the formation of ribosome, further exerts a significant effect on the tumor microenvironment (TME). Additionally, the combination of HF with other drugs or therapies obtained universal attention. Our results showed that HF has significant potential for clinical cancer treatment.

Prone position ventilation(PPV)is an essential therapeutic intervention for patients with refractory hypoxemic respiratory failure.The outbreak of coronavirus disease 2019(COVID-19)has further elevated the significance of PPV in clinical practice.Early enteral nutrition(EN)is considered a crucial measure for improving outcomes in critically ill patients.However,there remains considerable controversy regarding the implementation of EN during PPV.This review summarizes the research progress on the tolerance and safety of EN during PPV before and after the COVID-19 outbreak.It also highlights key strategies to enhance EN tolerance in prone-positioned patients,providing a clinical reference for improving patient management.

Objective To explore the occurrence and related factors of diarrhea in the early stage of enternal nutrition in critically ill patients, therefore providing guidance for the optimization of enteral nutrition. Methods A prospective cross-sectional study was conducted in 29 ICUs of 28 general hospitals of Zhejiang Province between June 1 and October 1, 2016. Patients who were admitted to ICU required for enteral nutrition were included and continuously observed for over 7 days or till discharged from ICU. The patient's general characteristics, severity of disease, enteral nutrition, diarrhea-related and prognostic indicators were recorded. Multivariable logistic regression was performed to analysis risk factors associated with diarrhea and in-hospital mortality. Results A total of 533 critically ill patientswere enrolled in this study. The overall incidence of diarrhea was 30.8％ (n = 164). Diarrhea occurred most frequently on the three days after EN, with a median duration of 2 (1, 3) days. The daily incidence of diarrhea were significantly different between groups (all P< 0.05), which were gradually reduced on day 7. Multivariable logistic regression analysis showed that prokinetic drugs (OR=1.82; 95％ CI: 1.24-2.65), APACHE II score (OR=1.04; 95％ CI: 1.02-1.07), post-pylorus enteral feeding (OR=1.90; 95％ CI:1.11-3.36) were independent risk factors for diarrhea, while interruption of EN (OR=3.74; 95％ CI: 1.85-7.54), APACHE II score (OR=1.07; 95％ CI: 1.04-1.11), vasoactive agent (OR=2.31; 95％ CI: 1.42-3.77), and timing (>48 h) (OR=2.00; 95％ CI: 1.08-3.70) were independent risk factors for in-hospital mortality. Conclusions Our study showed that APACHE II score, the use of prokinetic drugs, and post-pylorus enteral feeding were risk factors for diarrhea. Patients suffering diarrhea experienced increased ICU length of stay, increased the time of mechanical ventilation and in-hospital mortality compared with patients without diarrhea. Interruption of EN induced by diarrhea significantly increased the risk of in-hospital mortality.

Objective To detect the correlation of serum myoglobin (Mb) and creatine kinase (CK) levels in multiple trauma patients with outcome and renal failure and compare the prognostic value of the two predictors.Methods Forty-one patients with multiple trauma (ISS ≥ 16 points) were analyzed at days 1,3,7,and 14 posttrauma,for serum Mb and CK concentrations.Moreover,simplified acute physiology score Ⅱ (SAPS Ⅱ),injury severity score (ISS),as well as Glasgow coma score (GCS)at day 1 postrauma,final outcome,and presence or absence of renal failure were recorded.Correlation of serum Mb and CK with ISS,GCS,and SAPS Ⅱ was analyzed.Predictive values of Mb and CK for outcome and development of renal failure after multiple trauma were measured and compared at days 1,3,and 7 posttrauma,according to receiver operating characteristic (ROC) curve.Results Serum Mb concentration revealed a positive correlation with SAPS Ⅱ at each time point and with ISS at days 7 and 14,but a negative correlation with GCS at days 3,7,and 14.Similarly,serum CK concentration presented a positive correlation with SAPS Ⅱ at days 3,7,and 14 and with ISS at days 7 and 14,but a negative correlation with GCS at days 7 and 14.To predict outcome of the multiple trauma patients,area under the ROC curve for serum Mb at days 1,3,and 7 was 0.542,0.900,and 0.981 respectively and for serum CK was 0.232,0.771,and 0.968 respectively.To predict development of renal failure,area under the ROC curve for serum Mb at days 1,3,and 7 was 0.864,0.949,and 0.955 respectively and for serum CK was 0.480,0.889,and 0.939 respectively.Conclusions Serum Mb and CK are both predictive of outcome and development of renal failure following multiple trauma.Whereas in co；rast with CK,serum Mb appears to be a more sensitive marker.

Objective To investigate effect of hypothermia on coagulation function in major trauma patients and assess value of thromboelastography (TEG) monitoring.Methods Twenty-two patients with major trauma admitted to the emergency intensive care unit between January 2010 and June 2011 were enrolled in the study.The venous blood of the patients was sampled for TEG determination at different temperatures (37,35 and 33 ℃) to analyze variation of the indices including coagulation reaction time (R),clot formation time (K),rate of clot formation (Angle),maximum amplitude (MA)and coagulation index (CI).The patients were divided into normal coagulation group and abnormal coagulation group based on the CI value at 37 ℃ to analyze effects of temperature on TEG indices in both groups and their differences between groups.Results (1) Among 22 patients,TEG indices including R and K trended upward (P ＜ 0.01),but Angle,MA and CI trended downward (P ＜ 0.01) with decline of the temperatures.(2) K and Angle values,indicators of fibrinogen function,were obviously inhibited (P ＜ 0.05) with the temperature decreasing from 37 ℃ to 35 ℃,but other TEG indices had no significant changes.Whereas,all TEG indices were significantly inhibited when the temperature was decreased from 35 ℃ to 33 ℃.(3) There were significant differences in variation of each TEG index inhibited by hypothermia (P ＜ 0.01).All TEG indices showed significant differerces in the pairwise comparison,except for the differences between R and K as well as between Angle and MA (P ＜0.01).(4) R and K were increased,but Angle,MA and CI were decreased in both groups,with decline of the temperatures.Moreover,all TEG indices in the abnormal group were worse than those in the normal group.Conclusions Hypothermia has significant effect on coagulation function of patients with major trauma.TEG,which may be measured at any temperature,is more accurate in reflection of patients' actual coagulation function and is helpful for choice of an appropriate temperature in the mild hypothermia therapy.

Objective To investigate the risk factors of trauma induced coagulopathy and its effect on the outcome of ICU patients with severe trauma.Methods Totally 223 severe trauma patients admitted to emergency ICU within 24h after injuring between June,2008 and September,2009 were retrospectively analyzed.Injury severity score (ISS),APACHE Ⅱ score,coagulation function,routine blood test,biochemical test,and blood gas assay were completed for each patient. Hypoperfusion was defined as vasoactive agents usage,or base deficit (BD) ≥ 6 or shock index ≥ 1. Patients were divided into coagulopathy group and non-coagulopathy (control) group according to coagulation function.ISS,APACHE Ⅱ score,the occurrence of hypothermia and hypoperfusion were compared between the two groups.The risk factors of trauma induced coagulopathy were analyzed,and the multivariate logistic regression equation was formulated.Coagulation function and incidence of trauma induced coagulopathy were compared between nonsurvival and survival group.Results Fifty-two of 223 (23.3 ％ ) patients met the criteria of trauma induced coagulopathy.Mortality rate in this group was significantly higher than that in non-coagulopathy group (36.5％ vs 9.4％, P ＜ 0.01 ). Patients in both groups had the comparability in age,sex, injury mechanism and time after trauma.ISS,the incidence of hypothermia,hypoperfusion and severe traumatic brain injury in coagulopathy group were higher than those in non-coagulopathy group ( P ＜ 0.01 ).GCS,hemoglobin,hematocrit,and platelet counts in coagulopathy group were significantly lower than that in noncoagulopathy group (P＜ 0.01).Base deficit ≥6,GCS ≤ 8,and platelet counts were considered as the independent risk factors involved in trauma- induced coagulopathy according to logistic regression in this study.Coagulation function of non-survivors also remarkably attenuated when compared with survival group.Conclusions The incidence rate of trauma induced coagulopathy is high in severe trauma patients admitted to ICU within 24h. Trauma induced coagulopathy correlates well with ISS core,severe traumatic brain injury,shock and hypothermia,and results in high mortality.

Objective To develop a new method to measure pleural effusion volume by ultrasound in critically ill patients. Methods Forty-six critically ill patients admitted to emergency ICU were involved.The height of effusion (H),area of effusion at the middle section (S), thickness of effusion at middle-back line (T1) and posterior axillary line (T2) were measured by ultrasound in supine position at the end of expiration. The measured volume of pleural effusion (Vc) was calculated by H×S,and the actual volume of drainage (V) within 2 hours was also recorded. The correlation of actual volume of pleural effusion (V)with effusion height (H) ,thickness (T1, T2), area (S) and the calculated volume (Vc) were analyzed to decide the most accurate index and method. Results There was much better correlation between actual volume of effusion and S, (H & S), Vc, than these between V and T1 ,T2, H in all patients and subgroup, Vc had good correlation with V and very close to V(the average difference was 56 ml) when the actual volume was less than 500 ml,there was no difference[(417 ± 94)ml vs (402±95)ml, t = 1.095, P = 0. 285]. Both Logistic regression analysis and receiver operating characteristic (ROC) curve showed S was the most reliable index to predict the actual volume to exceed 500 ml,400 ml,and 300 ml when compared with H,S,T1 and T2. The corresponding threshold was 30.3 cm2 , 28.3 cm2 and 23. 1 cm2 , with the sensitivity and specificity of 0. 77 and 0. 88,0.72 and 1.0,0.95 and 1.0, respectively. Conclusions This new method based on measuring the area of effusion by ultrasound is more efficient and reliable than those traditional ones to measure the volume of pleural effusion. It's clinically valuable and easy to perform, and deserves broad application.
