Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Central nervous system （CNS） is a sophisticated system subject to complex regulation， which dominates the high-level neural activities of the human body. Due to its complex physiological structure and refined regulatory mechanism covering a variety of diseases， CNS is the place where many chronic， refractory and rare diseases occur. Nerve cell is the basic unit of CNS， and its dysfunction and death is the root cause of CNS diseases. Ferroptosis is a new form of programmed cell death proposed in recent years， and has been proved to be closely related to the production and development of multiple CNS diseases. Traditional Chinese medicine （TCM）， including Chinese herbs， acupuncture and moxibustion， and massage， has shown unique advantages in the treatment of CNS diseases for a long time. A large number of studies have demonstrated that TCM participates in the regulation of CNS diseases via regulating ferroptosis and shows a good research prospect. This paper summarized the characteristics of ferroptosis and discussed the association between ferroptosis and CNS diseases in pathological mechanism. We also reviewed the regulation of various CNS diseases by different TCM interventions through ferroptosis， providing references for TCM to participate in the treatment of CNS diseases properly in the future.

Objective:To explore the effectiveness and safety of comprehensive treatment of type 2 diabetes mellitus (T2DM) based on syndrome differentiation and diet.Methods:Prospective clinical study. A total of 147 patients with T2DM from September 2021 to August 2022 who met the inclusion criteria were included in the self-controlled trial. On the basis of diet and exercise intervention, the subjects were treated and observed with comprehensive treatment based on syndrome differentiation for 120 days. The main outcome indicators including TCM symptom score, fasting blood glucose (FPG), 2 hPG, HbA1c , Fasting insulin (FINS), C-peptide(C-PR), and the secondary outcome indicators including blood lipid (TC, TG, HDL-C, LDL-C), blood pressure, and safety indicators were performed before and after treatment.Results:After treatment, the FPG of subjects decreased from (8.75±2.26) mmol/L to (7.05±1.23) mmol/L, 2 hPG decreased from (10.75±3.01) mmol/L to (7.07±0.78) mmol/L, HbA1c decreased from (6.82±1.47)% to (5.49±0.63)%, and FINS decreased from (15.4±9.33) μIU/ml to (8.82±7.28) μIU/ml, C-PR decreases from (1.95±0.91) nmol/L to (1.72±1.53) nmol/L, SBP decreased from (137.51±17.94) mmHg to (125.79±7.57) mmHg, DBP decreased from (82.85±9.65) mmHg to (77.54±6.21) mmHg,TG decreased from (1.57±1.04) mmol/L to (1.25±1.24) mmol/L, HDL-C increased from　(1.48±0.41) mmol/L to (1.66±0.46)mmol/L. The above differences were statistically significant ( P<0.05). Conclusion:The comprehensive treatment of T2DM based on syndrome differentiation and diet can significantly reduce the blood glucose indicators including FPG, 2 hPG, HbA1c, FINS and C-PR, and benefit blood pressure and blood lipids with no adverse reactions.

Hepatosteatosis is characterized by abnormal accumulation of triglycerides(TG),leading to prolonged and chronic inflammatory infiltration.To date,there is still a lack of effective and economical therapies for hepatosteatosis.Oridonin(ORI)is a major bioactive component extracted from the traditional Chinese medicinal herb Rabdosia rubescens.In this paper,we showed that ORI exerted significant protective ef-fects against hepatic steatosis,inflammation and fibrosis,which was dependent on LXRα signaling.It is reported that LXRα regulated lipid homeostasis between triglyceride(TG)and phosphatidylethanol-amine(PE)by promoting ATCL and EPT1 expression.Therefore,we implemented the lipidomic strategy and luciferase reporter assay to verify that ORI contributed to the homeostasis of lipids via the regulation of the ATGL gene associated with TG hydrolysis and the EPT1 gene related to PE synthesis in a LXRα-dependent manner,and the results showed the TG reduction and PE elevation.In detail,hepatic TG overload and lipotoxicity were reversed after ORI treatment by modulating the ATCL and EPT1 genes,respectively.Taken together,the data provide mechanistic insights to explain the bioactivity of ORI in attenuating TG accumulation and cytotoxicity and introduce exciting opportunities for developing novel natural activators of the LXRα-ATGL/EPT1 axis for pharmacologically treating hepatosteatosis and metabolic disorders.

Objective:Our study aims to predict acute kidney injury (AKI) in acute myocardial infarction (AMI) by establishing a random forest model.Methods:By using the clinical database from affiliated Dongyang Hospital of Wenzhou Medical University, a total of 1 363 AMI cases were included. Then, 75% of participants were analyzed as training subsets and the remaining 25% were testing subsets. The CARET package in R was used to filter variables and build random forest. The prediction ability of established model was evaluated by specificity, sensitivity, accuracy, relative operating characteristic curve (ROC curve) in testing subsets. In addition, the performance of random forest was compared with other 3 commonly used machine learning algorithms (Artificial Neural Network, Naive Bayes, and Support Vector Machine).Results:In this study, 30 variables including the demographic information, risk factors of cardiovascular disease, vital signs at admission, laboratory tests were identified and used to establish our random forest prediction model. The area under the curve of the testing subsets ROC was 0.893. The specificity and sensitivity of prediction model was 0.791 and 0.866, respectively. And the first creatinine, first blood urea nitrogen, and D-dimer after admission, age, mechanical ventilation were the top-five factors in this model. After comparing various machine learning algorithms, random forest model had a better performance.Conclusion:The random forest model would be used to predict the occurrence of AMI with AKI.

Objective:To investigate the value of CT angiography (CTA) point sign in the treatment of patients with moderate amount basal ganglia hemorrhage at ultra-early stage by trephination and drainage or craniotomy, and its influence in the prognoses.Methods:One hundred and twenty-six patients with moderate amount basal ganglia hemorrhage (30-60 mL) admitted to our hospital from March 2017 to March 2019 were chosen in our study; these patients were evaluated and conformed to have the same tolerance of craniotomy or drainage; and their families agreed to the ultra-early surgical treatments; their clinical data were retrospectively collected. They all accepted CTA before operation. Among them, 68 were into the craniotomy group, including 38 into CTA spot sign negative sub-group and 30 into positive sub-group; 58 were into the trephination and drainage group, including 39 into CTA spot sign negative sub-group and 19 into positive sub-group. The differences of favorable prognosis rate and postoperative re-hemorrhage rate were compared between the craniotomy group and trephination and drainage group, as well as each two sub-groups.Results:The favorable prognosis rate and postoperative re-hemorrhage rate of patients in the craniotomy group (61.8% and 2.9%) were significantly lower as compared with those in the trephination and drainage group (82.8% and 15.5%, P<0.05). In the craniotomy group, the favorable prognosis rate and postoperative re-hemorrhage rate in the CTA spot sign positive sub-group (60.0% and 4.8%) were higher than those in the negative sub-group (63.2% and 2.1%), without significant differences ( P>0.05); in the trephination and drainage group, the favorable prognosis rate and postoperative re-hemorrhage rate in the CTA spot sign positive sub-group (63.2% and 36.8%) were significantly different as compared with those in the negative sub-group (92.3% and 5.1%, P<0.05). Conclusion:Among patients with moderate amount basal ganglia hemorrhage, prognoses can be effectively improved in the following treatments: if the patients have negative CTA spot sign, are evaluated to have low risk of postoperative re-hemorrhage after craniotomy or drainage, and are considered that the prognosis by drainage is better than that by craniotomy, trephination and drainage should be selected; if the patients have positive CTA spot sign, and are evaluated to have lower risk of postoperative re-hemorrhage by craniotomy than that by drainage, craniotomy should be selected.

Huacao Community Health Service Center has established an integrated chronic kidney disease (CKD) management system since 2015,which greatly improved CKD management in the community.From September 2016 to August 2017,4084 residents were screened by the family doctor team,975 were suspected to have CKD (23.87％),among whom 202 (20.72％) were referred to district CKD treatment center,and 197 (97.52％) were confirmed as CKD.The detection rate of suspected CKD among patients with hypertension and diabetes mellitus was the highest,which was much higher than that among outpatients and those with routine health check up.It is suggested that the integrated management of CKD should be widely implemented to cope with the prevalence of CKD,particularly for those with hypertension and diabetes.

Objective To establish an inactivated viral particle-based ELISA for the detection of antibodies against Middle East respiratory syndrome coronavirus (MERS-CoV) in serum samples collected from a MERS-CoV associated case. Methods Serum samples were collected from 10 newborns and 40 healthy adults. A viral particle-based ELISA was established by using the inactivated MERS-CoV virions as antigen. The levels of IgM and IgG antibodies in the serum samples were detected by the established ELISA and the cut-off values for positive detection were determined. Then the inactivated MERS-CoV virion-based ELISA was used to detect the antibodies against MERS-CoV in 5 serum samples collected from the first im-ported MERS case in China. Results The cut-off values of IgM and IgG antibodies in serum samples for ELISA were determined to be A450 readings of 0. 32 and 0. 42, respectively. The titers of IgM and IgG anti-bodies in serum samples collected at early admission to hospital from the first imported MERS case in China were both 1 ︰ 40. Seroconversion occurred 2 weeks after his admission to hospital with the titers of IgM and IgG reaching to 1 ︰ 320. Conclusion The inactivated MERS-CoV virion-based ELISA was established successfully and could be used for the detection of serum antibodies (IgG and IgM) in MERS associated cases.

Objective To evaluate the efficacy of atrial septostomy in idiopathic pulmonary arterial hypertension(IPAH) patients complicating right ventricular failure.Methods This retrospective analysis included 5 IPAH patients (3 males,(29.3 ± 15.2) years old) with right ventricular failure which were refractory to conventional and target-specific medication in Shanghai Chest Hospital from March to July 2014.Graded balloon dilation septostomy procedures were performed in all 5 patients.Results Successful atrial septostomy was achieved in 5 attempts with no procedure-related complications.Immediately post procedure,the mean systemic oxygen saturation decreased from (98.0 ± 1.8) ％ to (86.4 ± 3.2) ％ (P =0.002),while the mean right atrial pressure decreased from(18.9 ± 1.7) mmHg(1 mmHg =0.133 kPa) to (16.0 ± 1.3)mmHg(P =0.039) and the mean cardiac index increased from (2.1 ±0.3)L · rain-1 · m-2 to (2.7 ± 0.5) L · min 1 · m-2 (p =0.029).Mean follow-up was (6.2 ± 1.8) months.Cardiac functional class (WHO) was 3 in 3 patients and 4 in 2 patients before the procedure,and increased 1 class in all patients during follow-up(P =0.062).Exercise endurance(6-min walk test)also improved from (289.2 ± 16.9)m to (320.4 ± 19.6) m (P =0.019),while B-type natriuretic peptide (BNP) level declined from (550.0 ± 35.7) ng/L to (218.0 ± 36.2) ng/L (P ＜ 0.001).Except one patient developed spontaneous closure of created defect,right to left shunt at atrial septal level was evidenced by echocardiography during follow-up in the rest 4 patients.Conclusions Atrial septostomy is safe and can improve hemodynamics and heart function in selected IPAH patients with right heart failure.Atrial septostomy can be used as a palliative treatment for IPAH and further study is warranted to evaluate the long-term efficacy of this procedure.

Objective To evaluate the efficacy and safety of domestic palonosetron hydrochlo-ride injection on its prevention of postoperative nausea and vomiting.Methods A multi-centered,ran-domized,double-blinded and placebo-controlled clinical trial was carried out.A total of 281 patients were enrolled,with 141 of patients in study group and 140 of patients in control group respectively. 0.075 mg of intravenous palonosetron hydrochloride injection was delivered in the study group before anesthesia induction.The drug was substituted by 1.5 ml of NS in the control group.All anesthesia inductions were conducted by the intravenous injection of propofol,fentanyl and rocuronium,and were maintained with sevoflurane and fentanyl.Complete remission rate and treatment failure cut-off time of vomiting were evaluated at 0-6 h,6-72 h,0-72 h postoperatively.Results In the study group CR% 0-6 h,6-72 h and 0-72 h were 107 (75.89%),104 (73.76%)and 92 (65.25%),the control group was 81 (57.86%),70 (50%)and 62 (42.86%),CR% of the study group was significantly higher than that of the control group (P <0.01).Insignificant statistical difference but significant clin-ical difference exists in their treatment failure cut-off time,386.5 min and 300.0 min,respectively be-tween the groups.Conclusion Domestic palonosetron hydrochloride injection is safe and effective in the prevention of postoperative nausea and vomiting.
