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.

OBJECTIVE: To conduct qualitative and quantitative analyses of Tripterygium hypoglaucum in Yinning Tablets, a compound preparation of traditional Chinese herbal medicine. METHODS: Thin-layer chromatography (TLC) was used for qualitative analysis of Tripterygium hypoglaucum in Yining Tablets and the analytical protocols were optimized. High-performance liquid chromatography (HPLC) was used to quantitatively analyze the content of triptolide (the main active ingredient of Tripterygium hypoglaucum) in Yinning Tablets. RESULTS: The results of TLC analysis showed that the test sample of Yinning Tablets and the positive control samples both produced clear, well separated spots without obvious interference in the blank samples. Assessment of the influences of the thin-layer plates from different manufacturers, temperature and humidity on the test results demonstrated good durability of the test. HPLC analysis of triptolide showed a good linear relationship within the concentration range of 1-100 μg/mL (regression equation: A=22.219C-19.165, r=0.9999); the contents of triptolide in 3 batches of Yinning tablets were 0.34, 0.34, and 0.28 μg per tablet, all within the range of 0.28-0.34 μg per tablet. It was finally determined that each Yinning tablet should not contain more than 0.6 μg of triptolide. CONCLUSION TLC and HPLC are simple, accurate, durable and specific for qualitative and quantitative analyses of Tripterygium hypoglaucum in Yinning Tablets.

In ischemic stroke sequela phase, Rehmanniae Radix Praeparata-Corni Fructus drug pair has the effect in protecting damaged neurons, but its mechanism has not been clear. In this study, network pharmacology was used to predict the mechanism of Rehmanniae Radix Praeparata-Corni Fructus in the treatment of ischemic stroke sequela. Through database search and literature retrie-val, 40 active ingredients of Rehmanniae Radix Praeparata and Corni Fructus were obtained, and their targets were obtained through STITCH and TCMSP databases. The targets of ischemic stroke sequela were obtained through OMIM,GAD,TTD and DrugBank databases. By screening the intersections of active ingredients targets and stroke treatment targets, 21 potential targets were obtained. The DAVID database was used for GO enrichment analysis and KEGG pathway analysis of potential targets. GO enrichment analysis showed that Rehmanniae Radix Praeparata-Corni Fructus were mainly involved in regulation of blood pressure, negative regulation of extrinsic apoptotic signaling and positive regulation of angiogenesis. KEGG pathway analysis showed that Rehmanniae Radix Praeparata-Corni Fructus could inhibit inflammatory response and apoptosis signaling pathway by regulating HIF-VEGFA signaling pathway in neural stem cell proliferation, TNF signaling pathway and NF-kappaB signaling pathway. Molecular docking technique was used to verify that Rehmanniae Radix Praeparata-Corni Fructus component has a good binding activity with potential targets. The results showed that in ischemic stroke sequela phase, Rehmanniae Radix Praeparata-Corni Fructus drug pair could play an important role in recovering neural function, promoting the proliferation of neural stem cells, angiogenesis, preventing neural cells apoptosis and regulating inflammatory factors.

Facial reconstruction is a way to recover facial morphology by restoring soft tissues based on unidentified skulls using the knowledge of anatomy, anthropology, aesthetics, and computer science. It is applied in forensic science, oral plastic surgery and archeology, and especially plays an important role in the identification of the origin of the unknown corpses in forensic science. Facial reconstruction is the supplementary means of identification when other approaches （such as DNA comparison, imaging matching, dental records comparison, etc.） cannot identify individual identity. Facial soft tissue thickness （FSTT） is the basis of facial reconstruction and with the development of imaging and computer science, the techniques for measuring FSTT are improving rapidly and many related researches have appeared. This paper summarizes the application of facial reconstruction in forensic science, the accuracy of different methods and the research progress of this field to provide reference to this field.

OBJECTIVETo investigate the hemostatic effect of spleen-invigorating, qi-replenishing and blood-containing formula on simvastatin-induced zebrafish hemorrhage model, and to compare with the effect of clearing heat and cooling blood formula.

METHODSZebrafishes from breed A B line were treated with 0.5 µmol/L simvastatin for 24 hours to establish zebrafishes hemorrhage model. Under strict blinded experimental conditions, the above mentioned zebrafishes were then treated with experimental drug of different concentrations at the maximum non-lethal dose. The intervention effect of spleen-invigorating, qi-replenishing and blood-containing formula was comprehensively assessed by examining the main observational parameters, such as bleeding reduction rate and hemostasis rate while referring to additional parameters, such as blood flow, improvement rate of blood flow, velocity of movement, improvement rate of motion, which are characteristics of spleen qi deficiency.

RESULTSWhen the hemostatic effect of experimental drug B1 at the concentrations of 500 and 1 000 µg/ml, zebrafish bleeding rates were 30% and 15%, the hemostatic rate was 60% and 80%, respectively; when the experimental drug B2 at concentration of 500 and 1 000 µg/ml, Zebrafish bleeding rates were 45% and 40%, the hemostatic rate was 40% and 47%, respectively, showing that experimental drug B1 was superior to B2 in terms of decreasing bleeding rate and improving hemostatic effect in zebrafish. In the equal concentration, the experimental drug B1 was superior to B2 in terms of increasing and improving the blood flow of hemorrhagic zebrafish. Promotion and improvement of motion: in equal concentration, experimental drug B1 was superior to B2 in terms of promoting the motion velocity and increasing the improving rate of motion in zebrafish.

CONCLUSIONThe spleen-invigorating, qi-replenishing and blood-containing formula displays a good hemostatic effect on simvastatin-induced hemorrhage of zebrafish. It also boosts the blood flow and motion velocity in hemorrhagic zebrafish, therefore, providing an experimental basis for the treatment of syndrome of spleen failing to control blood by spleen-invigorating, qi-replenishing and blood-containing formula.

OBJECTIVETo evaluate the effect of sodium tanshinone IIA sulfonate (STS) in preventing postoperative peritoneal adhesions in rats and explore the mechanisms.

METHODSSixty SD rats were randomized into 4 equal groups, including a blank control group, adhesion model group, and high-, moderate-, and low-dose STS-treated groups, and were subjected to injuries of the parietal peritoneum and cecum to induce peritoneal adhesions, followed by intraperitoneal administration of saline and STS at the doses of 20, 10, and 5 mg/kg for 7 consecutive days, respectively. Another 15 untreated rats served as the blank control group. The adhesion scores in each group were recorded after the treatments; the activity of tissue-type plasminogen activator (tPA) in peritoneal lavage fluid was measured, tPA/PAI-1 protein ratio in the peritoneal tissue was determined by ELISA, and the expressions of TGF-β1 and collagen I were detected by immunohistochemistry. The anastomotic healing model was used to assess the impact of STS on wound healing.

RESULTSIntraperitoneal administration of STS effectively prevented peritoneal adhesion without affecting anastomotic healing in the rats. Compared with the adhesion model group, the STS-treated groups showed increased peritoneal lavage fluid tPA activity and tPA/PAI-1 ratio in the ischemic tissues with lowered TGF-β1 and collagen I expressions in the ischemic tissues.

CONCLUSIONSIntraperitoneal administration of STS can prevent peritoneal adhesion and enhance local fibrinolysis in rats, and these effects may be mediated by TGF-β signaling pathway.

Objective: To assess the impact of viable myocardium in left ventricular aneurysm (LVA) and ventricular arrhythmia on prognosis of LVA patients.
Methods: A total of one hundred and sixty LVA patients who received99Tcm-MIBI SPECT and18F-FDG PET were enrolled, including 139 male and 21 female with the mean age of (58 ± 10) years.There were 42 (26.3%) patients combining ventricular arrhythmia. LVEDV, LVESV and LVEF were detected. Semi-quantitative analysis of myocardium perfusion imaging was conducted, viable myocardium in aneurysm was deifned as the perfusion-metabolism mismatch score (MMS) ≥ 2.0. According to myocardium viability, the patients were divided into 2 groups: No viability group,n=97 and With viability group,n=63;based on ventricular arrhythmia, the patients were divided into another 4 groups: Group①, viability-, ventricular arrhythmia-, n=68, Group②, viability-, ventricular arrhythmias+,n=29, Group③, viability+, ventricular arrhythmias-,n=50 and Group④, viability+,ventricular arrhythmias+,n=13. The average follow-up time was (50 ± 7) months, the end point was cardiac death. The survival curve was obtained by Kaplan-Meier method and survival rates were compared by Log-rank analysis.
Results: The mean LVEF in 160 patients was (34 ± 11) %, cardiac death occurred in 19 (11.9%) patients. Long-term survival rates in Groups①,② and③ were 94.1%, 89.7% and 86.0%, respectively,P>0.05; while in Group④, the survival rate was 61.5%, which was lower than the other 3 groups,P=0.004. Multivariate Cox regression analysis showed that female (HR=5.101, 95% CI 1.853-14.044, P=0.002), GPET-ESV (HR=1.009, 95% CI 1.002-1.015,P=0.013), interaction between MMS and ventricular arrhythmia (HR=1.368, 95%CI 1.113-1.681,P=0.003) were independent risk factors for cardiac death;while surgical treatment (HR=0.199, 95% CI 0.054-0.742,P=0.016) could decrease the risk of cardiac death.
Conclusion: Patients with viable aneurysm and ventricular arrhythmia had poor long-term prognosis; while early and active treatment is needed for them (surgery with anti-arrhythmic therapy).
