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.

Cryopreservation of rare testicular-retrieved spermatozoa for intracytoplasmic sperm injection (ICSI) in patients with severe oligozoospermia and azoospermia remains a major challenge in clinical practice. This study evaluated the Cryopiece system as a potential technique to cryopreserve rare human spermatozoa for ICSI. Small numbers of ejaculated (24 patients) and testicular (13 patients) spermatozoa were cryopreserved using the Cryopiece system. The total number of recovered spermatozoa and motility were assessed after thawing. Thirty-seven couples underwent ICSI using spermatozoa cryopreserved by the Cryopiece system, and ICSI outcomes (rates of fertilization, embryo cleavage, and clinical pregnancy) were evaluated. The average sperm post-thaw retrieval rate was 79.1%, and motility was 29.7%. Ejaculated spermatozoa had a higher post-thaw motility (32.5%) than testicular spermatozoa (21.8%; P = 0.005). ICSI achieved a fertilization rate of 61.9%, embryo cleavage rate of 84.6%, and clinical pregnancy rate of 43.3%. The ICSI outcomes in the ejaculated and testicular frozen-thawed spermatozoa were similar. Assisted oocyte activation (AOA) after ICSI with motile (72.1%) or immotile (71.9%) spermatozoa resulted in a significantly higher fertilization rate than that when using motile spermatozoa without AOA (52.0%; P = 0.005). However, AOA did not enhance the clinical pregnancy rate (55.6% or 40.0% vs 35.3%; P = 0.703). The Cryopiece system is simple and useful for the cryopreservation of small numbers of ejaculated or testicular spermatozoa for ICSI in patients with severe oligozoospermia or nonobstructive azoospermia.

Objective:To compare the effect of hybrid open-endovascular repair (HOER) and Viabahn open revascularization technique (VORTEC)+HOER in the treatment of thoracoabdominal aortic aneurysms (TAAA).Methods:From Apr 2005 to Jul 2019, 33 TAAA patients underwent HOER including 21 cases of standard HOER, and 12 of VORTEC+HOER. The intraoperative renal ischemia time (RIT), incidence of postoperative acute kidney injury (AKI), rate of renal artery patency (RAP) and another short-term outcome were observed.Results:RIT was significantly shorter in the VORTEC+HOER group than in the standard treatment group [(9±3) minutes vs. (15±6) minutes, P<0.05]. The increase in serum creatinine (SCr) levels on the 1st postoperative day in the standard treatment group was significantly higher than that in the VORTEC+HOER group [(1.68±0.79) μmol/L vs. (1.05±0.06) μmol/L, P<0.05]. AKI occurred in 5 patients in the standard HOER treatment group (5/21, 24%), while no patient experienced AKI in the VORTEC+HOER group (0/12, 0). Conclusion:VORTEC significantly reduces RIT and postoperative SCr increasing, thereby potentially decreasing the incidence of postoperative AKI.

Objective:To observe the clinical efficacy of Yi Jin Jing (Sinew-transforming Qigong Exercises) for primary osteoporosis in the elderly.Methods:Eighty old patients with primary osteoporosis were randomized into a Yi Jin Jing group and a medication group,40 cases in each group.The Yi Jin Jing group was intervened by Yi Jin Jing (Sinew-transforming Qigong Exercises) training,while the medication group was intervened by oral administration of alendronate sodium tablet.Prior to and after 6-month intervention,the bone mineral density (BMD) of the proximal femur,visual analog scale (VAS) and activities of daily living (ADL) were estimated.Results:There were no significant differences in the BMD of the proximal femur,and VAS and ADL scores between the two groups before the intervention (P＞0.05).After 6-month intervention,the above items all improved significantly in both groups (both P＜0.01);the improvements in VAS and ADL scores in Yi Jin Jing group were more significant than those in the medication group (P＜0.01),while the between-group difference in the BMD of the proximal femur was statistically insignificant (P＞0.05).Conclusion:Practice of Yi Jin Jing (Sinew-transforming Qigong Exercises) can effectively ameliorate the BMD in the elderly with primary osteoporosis,and it can reduce the pain and improve ADL,with a better general effect compared to oral administration of alendronate sodium tablet.

BACKGROUNDPrior studies have reported controversial conclusions regarding the risk of adverse cardiovascular events in patients using proton-pump inhibitors (PPIs) combined with clopidogrel therapy, causing much uncertainty in clinical practice. We sought to evaluate the safety of PPIs use among high-risk cardiovascular patients who underwent percutaneous coronary intervention (PCI) in a long-term follow-up study.

METHODSA total of 7868 consecutive patients who had undergone PCI and received dual antiplatelet therapy (DAPT) at a single center from January 2013 to December 2013 were enrolled. Adenosine diphosphate (ADP)-induced platelet aggregation inhibition was measured by modified thromboelastography (mTEG) in 5042 patients. Propensity score matching (PSM) was applied to control differing baseline factors. Cox proportional hazards regression was used to evaluate the 2-year major adverse cardiovascular and cerebrovascular events (MACCEs), as well as individual events, including all-cause death, myocardial infarction, unplanned target vessel revascularization, stent thrombosis, and stroke.

RESULTSAmong the whole cohort, 27.2% were prescribed PPIs. The ADP-induced platelet aggregation inhibition by mTEG was significantly lower in PPI users than that in non-PPI users (42.0 ± 30.9% vs. 46.4 ± 31.4%, t = 4.435, P < 0.001). Concomitant PPI use was not associated with increased MACCE through 2-year follow-up (12.7% vs. 12.5%, χ2 = 0.086, P = 0.769). Other endpoints showed no significant differences after multivariate adjustment, regardless of PSM.

CONCLUSIONIn this large cohort of real-world patients, the combination of PPIs with DAPT was not associated with increased risk of MACCE in patients who underwent PCI at up to 2 years of follow-up.

Objective To evaluate the safety and efficacy of transplantation of purified CD34 + cells (PCCs) in treatment of critical limb ischemia (CLI) caused by thromboangiitis obliterans (TAO).Methods From May 2009 to June 2015,34 TAO-induced-CLI cases underwent PCCs transplantation.None of these patients were eligible for surgical or endovascular revascularization.G-CSF was subcutaneously injected for 5 days before peripheral CD34 + cells were isolated,purified and intramuscularly injected in the limbs.Patients were regularly follow-up.Results Technical success was achieved in all cases.The mean number of transplanted cells was (7.5 ± 2.4) × 105/kg.The follow-up was accomplished in 32 cases,ranging from 6 to 79 months (mean 45 ±24 months),and two patients were lost.Wong-Baker FACES pain rating scale score significantly decreased from 8.0 ±2.0(4-10)to 2.2 ±3.1 (P ＜0.05) at 1 month.The Peak pain-free walking time improved from (4.0 ± 2.0) min to (13.5 ± 5.3) min (P ＜ 0.05) at 3 months and (19.0 ± 3.1) min (P ＜ 0.05) at 6 months.The ankle-brachial index increased from 0.42 ± 0.20 to 0.50 ± 0.10 (P ＜ 0.05) at 3 months and 0.52 ± 0.11 (P ＜ 0.05) at 6 months,respectively.Transcutaneous partial oxygen pressure rose from (25 ± 11) mmHg to (48 ± 11) mmHg(P ＜ 0.05) at 3 months and (58 ± 10) mmHg (P ＜ 0.001) at 6 months,respectively.Ulcers healed in 21 out of 22 patients at (5 ± 4) months.The overall amputation-free survival rate was 94.1％ at 6 months and 91.2％ at 48 months.No major adverse events were observed perioperatively or postoperatively.Conclusions Transplantation of PCCs could yield safe,satisfactory and durable treatment outcomes in patients with TAO-induced-CLI.

OBJECTIVEVery early-onset coronary artery disease (CAD) is a great challenge in cardiovascular medicine throughout the world, especially regarding its early diagnosis. This study explored whether circulating microRNAs (miRNAs) could be used as potential biomarkers for patients with very early-onset CAD.

METHODSWe performed an initial screening of miRNA expression using RNA isolated from 20 patients with angiographically documented very early-onset CAD and 20 age- and sex-matched normal controls. For further confirmation, we prospectively examined the miRNAs selected from 40 patients with very early-onset CAD and 40 angiography-normal controls.

RESULTSA total of 22 overexpressed miRNAs and 22 underexpressed miRNAs were detected in the initial screening. RT-qPCR analysis of the miRNAs obtained from the initial screening revealed that four miRNAs including miR-196-5p, miR-3163-3p, miR-145-3p, and miR-190a-5p exhibited significantly decreased expression in patients compared with that in controls (P<0.05). The areas under the receiver operating characteristic curve for these miRNAs were 0.824 (95% CI, 0.731-0.917; P<0.001), 0.758 (95% CI, 0.651-0.864; P<0.001), 0.753 (95% CI, 0.643-0.863; P<0.001), and 0.782 (95% CI, 0.680-0.884; P<0.001), respectively, in the validation set.

CONCLUSIONTo our knowledge, this is an advanced study to report about four serum miRNAs (miR-196-5p, miR-3163-3p, miR-145-3p, and miR-190a-5p) that could be used as novel biomarkers for the diagnosis of very early-onset CAD.
