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 explore the computed tomography angiography(CTA)and clinical features of Takayasu's arteritis(TA)with peripheral artery involvement.Methods In this retrospective study,CTA scan was performed in a total of 184 TA patients.TA patients were divided into two groups:60 patients within peripheral artery involvement(peripheral artery involvement group)and 124 patients without peripheral artery involvement(peripheral artery non-involvement group).The difference in comparison of clini-cal data and CTA findings were analyzed.Results A total of 194 peripheral arteries were involved in 60 patients.The most suscep-tible peripheral artery were axillary artery(52,26.8％),middle cerebral artery(26,13.4％)and femoral artery(22,11.3％).In the peripheral artery involvement group,the most common CTA manifestation was luminal stenosis(141,72.7％).The lumen dilata-tion,lumen stenosis with dilatation and wall calcification were not easy to be observed.The age and duration of disease in peripheral artery involvement group were significantly greater than those in peripheral artery non-involvement group(P＜0.05).The proportion of the peripheral artery involvement group in the active phase was significantly lower than that of the peripheral artery non-involvement group(P＜0.05).The incidence of pain in the limbs in peripheral artery involvement group was significantly higher than that in peripheral artery non-involvement group(P＜0.05).The utilization rate of tocilizumab in the peripheral artery involvement group was significantly higher than that in the peripheral artery non-involvement group(P＜0.05).Conclusion TA involving peripheral arteries is more common in patients with a long course of disease and in the inactive phase.Patients are prone to pain in their limbs.The CT A manifestations of these patients are also special,that is,the involved peripheral arteries are not prone to lumen dilatation and wall calcification.

Objective:To compare the recurrence of common bile duct stones (CBDS) in patients with gallstones and concurrent CBDS treated by two surgical approaches: synchronous laparoscopic cholecystectomy (LC) combined with laparoscopic common bile duct exploration (LCBDE) (LC+LCBDE) and synchronous LC combined with intraoperative endoscopic sphincterotomy (IO-EST) (LC+IO-EST).Methods:From Apr 2013 to Apr 2020, the clinical data of 903 patients with gallstones with CBDS who were admitted to the Clinical Medical College, Yangzhou University were retrospectively analyzed.Results:Based on the chosen surgical method, we categorized 389 cases into group A (LC+LCBDE) and 514 cases into group B (LC+IO-EST). Our findings revealed that group A had a significantly lower rate of CBDS recurrence and re-recurrent CBDS compared to group B (4.4% vs. 8.4%, P=0.024; 0.8% vs. 3.1%, P=0.010). Moreover, Logistic regression analysis after inverse probability of treatment weighting, revealed that the surgical approach implemented in group A was an independent protective factor of recurrent CBDS and second recurrence of CBDS ( OR=0.482, 95% CI: 0.365-0.637, P<0.001; OR=0.118, 95% CI:0.080-0.173, P<0.001). Conclusion:LC+LCBDE is an optimal treatment option to LC+IO-EST for patients with gallstones combined with CBDS and common bile duct ≥8 mm.

Objective:To evaluate the initial clinical outcome of applying a comprehensive debulking procedure centered on the digital and plantar flaps with comparatively healthy proximal pedicle to reconstruct the hypertrophic toes and forefoots in one-stage surgery in multiple toes macrodactyly in children.Methods:The clinical data of children with macrodactyly deformity treated by the Department of Burn and Plastic Surgery in Children’s Hospital of Chongqing Medical University from January 2022 to October 2023 were retrospectively analyzed. Design toe and plantar arbitrary flaps with a few vascular perforating branches which pedicle at the comparatively healthy proximal side and resect all tissues beyond the normal length. In severe toe, a composite tissue nail-flap with the artery was dissected to reconstruct the toenail. Fat debulking on the surface of deep plantar fascia as well as within the osseofascial sheath, resecting partially of the fatty infiltrated nerve, transverse and longitudinal osteotomy to shorten and narrowed phalanxes without epiphyseal block, arthroplasty and flexor tendon tightening were performed. Finally, toes shaped by wrapping toe flaps, and pelmas restored by plantar flaps which both with comparatively healthy proximal pedicle. The operation time, healing time, and whether the toes and toenails are preserved were all recorded. The maximum circumference of both foot, the difference in shoe size, the presence of skin ulcers, wound scars, toe webbing morphology, the presence of basic sensation, and the satisfaction of parents were followed-up after surgery. The modified follow-up questionnaire was used to evaluate the surgical effect, the total score is 0-12 points, and the higher the score, the better the surgical outcome. Descriptive methods was used for statistical analysis, and the measurement data conforming to normal distribution were expressed as Mean±SD.Results:A total of 15 patients were enrolled, including 11 males and 4 females. The median age at the time of operation was 2.75 years (0.9-10.8 years). There were 11 cases with 2 toes and 4 cases with 3 toes, a total of 34 toes involved. The average surgical duration was 4.13 hours (3.25 hours for 2 toes and 5.00 hours for 3 toes). Only one severe case with 3 toes involved was amputated the biggest toe ray and totally 2 toe nail flaps were harvested unsuccessfully intraoperative. Except 3 toes had distal skin partially necrosis and 2 nail flaps were completely necrotic which healed after dressing changes, the rest of the toes were healing well after operation. The average follow-up time was 4.8 months (3-11 months), the difference of circumference was less than 1.5 cm, as well as in length was less than 0.5 cm between feet and all children were able to wear the appropriate shoes with same size. A total of 4 toes failed to retain toenails, and 1 had a very thin toenail. Except for one case with insufficient web depth, the other toe webs were close to normal. There was no skin ulcer occurred, the basic sensation of the feet was present, and wound scars were inconspicuous. The score of the modified questionnaire was 10.54±0.88, all parents were satisfied with the results.Conclusion:Comprehensive procedure centered on the digital and plantar flaps with comparatively healthy proximal pedicle for debulking multiple toes macrodactyly in children could completely excise distal hypertrophic tissues in a single operation, and the size of the affected feet and toes can be greatly reduced to wearing shoes of the same size, and have a high success rate in preserving the toes, as well as nails. The reconstructed feet, toes and toe webbing have near-normal morphology, hidden scar, no ulcers after walked and achieve a good initial effect.

Tu-Xian decoction (TXD), a traditional Chinese medicine (TCM) formula, has been frequently administered to manage diabetic cognitive impairment (DCI). Despite its widespread use, the mechanisms underlying TXD's protective effects on DCI have yet to be fully elucidated. As a significant regulator in neurodegenerative conditions, death-associated protein kinase-1 (DAPK-1) serves as a focus for understanding the action of TXD. This study was designed to whether TXD mediates its beneficial outcomes by inhibiting DAPK-1. To this end, a diabetic model was established using Sprague-Dawley (SD) rats through a high-fat, high-sugar (HFHS) diet regimen, followed by streptozotocin (STZ) injection. The experimental cohort was stratified into six groups: Control, Diabetic, TC-DAPK6, high-dose TXD, medium-dose TXD, and low-dose TXD groups. Following a 12-week treatment period, various assessments-including blood glucose levels, body weight measurements, Morris water maze (MWM) testing for cognitive function, brain magnetic resonance imaging (MRI), and histological analyses using hematoxylin-eosin (H&E), and Nissl staining-were conducted. Protein expression in the hippocampus was quantified through Western blotting analysis. The results revealed that TXD significantly improved spatial learning and memory abilities, and preserved hippocampal structure in diabetic rats. Importantly, TXD administration led to a down-regulation of proteins indicative of neurological damage and suppressed DAPK-1 activity within the hippocampal region. These results underscore TXD's potential in mitigating DCIvia DAPK-1 inhibition, positioning it as a viable therapeutic candidate for addressing this condition. Further investigation into TXD's molecular mechanisms may elucidate new pathways for the treatment of DCI.

Osteoporotic vertebral compression fracture (OVCF) can lead to lower back pain and may be even accompanied by scoliosis, neurological dysfunction and other complications, which will affect the daily activities and life quality of patients. Vertebral augmentation is an effective treatment method for OVCF, but it cannot correct unbalance of bone metabolism or improve the osteoporotic status, causing complications like lower back pain, limited spinal activities and vertebral refracture. The post-operative systematic and standardized rehabilitation treatments can improve curative effect and therapeutic efficacy of anti-osteoporosis, reduce risk of vertebral refracture, increase patient compliance and improve quality of life. Since there still lack relevant clinical treatment guidelines for postoperative rehabilitation treatments following vertebral augmentation for OVCF, the current treatments are varied with uneven therapeutic effect. In order to standardize the postoperative rehabilitation treatment, the Spine Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized relevant experts to refer to relevant literature and develop the "Guideline for postoperative rehabilitation treatment following vertebral augmentation for osteoporotic vertebral compression fracture (2022 version)" based on the clinical guidelines published by the American Academy of Orthopedic Surgeons (AAOS) as well as on the principles of scientificity, practicality and advancement. The guideline provided evidence-based recommendations on 10 important issues related to postoperative rehabilitation treatments of OVCF.

Objective:To analyze the interim clinical efficacy of laparoscopic and open distal gastrectomy for gastric cancer in elderly patients.Methods:The prospective randomized controlled study was conducted. The clinicopathological data of 102 patients aged ≥65 years who underwent distal gastrectomy for gastric cancer in the Nanfang Hospital of Southern Medical University from September 2014 to May 2018 were collected. After excluding 6 patients, 96 patients were finally included. Based on random number table, patients were allocated into two groups. Patients undergoing laparoscopic distal gastrectomy were allocated into laparoscopic group, and patients undergoing open distal gastrectomy were allocated into open group, respectively. Obser-vation indicators: (1) grouping situations of the enrolled patients; (2) intraoperative situations; (3) postoperative situations; (4) follow-up. Follow-up using outpatient examination and telephone interview was conducted to detect complications in the postoperative 30 days up to July 2018. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M( P25, P75) or M(range), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. Comparison of ordinal data was analyzed using the non-parameter Mann-Whitney U test. Results:(1) Grouping situations of the enrolled patients: a total of 96 patients were selected for eligibility. There were 66 males and 30 females, aged from 65 to 85 years, with a median age of 69 years. There were 49 of 96 patients in the laparoscopic group and 47 patients in the open group. (2) Intraoperative situations: patients in the two groups underwent distal gastrectomy successfully with D 2 lymphadenectomy, without intra-operative conversion to laparotomy. The volume of intraoperative blood loss and surgical incision length were 50 mL(50 mL,100 mL) and (7.1±1.7)cm for the laparoscopic group, respectively, versus 100 mL(100 mL,200 mL) and (19.1±1.7)cm for the open group, showing significant differences between the two groups ( Z=?3.779, t=?34.880, P<0.05) . (3) Postoperative situations: the number of lymph node dissected, time to postoperative initial out-of-bed activities, time to postoperative first flatus, time to postoperative first liquid food intake, time to postoperative first semi-liquid food intake, time to drainage tube removal, duration of postoperative hospital stay were 49(35,62), 1.9 days(1.3 days,2.9 days), 2.6 days(2.2 days,2.9 days), 3.4 days(2.7days,4.0 days), 5.9 days(4.7 days,7.7 days), 4.9 days(3.5 days,6.8 days), 7.7 days(6.7 days,8.9 days) for the laparoscopic group, respectively, versus 40(27,51), 2.5 days (1.8 days,3.3 days), 2.6 days(2.2 days,2.9 days), 3.9 days(2.9 days,5.7 days), 4.9 days(3.9 days, 5.9 days), 6.3 days(4.7 days,8.9 days), 8.7 days(6.9 days,11.7 days), showing significant differences between the two groups ( Z=?2.354, ?2.210, ?2.743, ?2.474, ?2.906, ?2.503, ?2.359, P<0.05). (4) Follow-up: patients in the two groups received 30 days of follow-up. During the follow-up, 8 patients in the laparoscopic group had postoperative complications, including 1 case with Clavien-Dindo grade Ⅰ complications, 7 cases with Clavien-Dindo grade Ⅱ complications, and no patient with Clavien-Dindo grade Ⅲ complications. Thirteen patients in the open group had postoperative complications, including 2 cases with Clavien-Dindo grade Ⅰ complications, 10 cases with Clavien-Dindo grade Ⅱ complications, and 1 case with Clavien-Dindo grade Ⅲ complications. There was no significant difference in the above indicators between the two groups ( χ2=1.135, 1.973, 1.054, P>0.05). The overall complication rate was 16.3%(8/49) and 27.7%(13/47) for the laparoscopic group and open group, respectively, showing no significant difference between the two groups ( χ2=1.803, 99.7% confidence interval as ?∞ to 2.4%, P>0.05). The upper limit of 99.7% confidence interval was less than non-inferiority level of 15%, interim analysis of which showed that the complication rate of the laparoscopic group was non-inferior to the open group. Conclusion:For elderly patients undergoing laparoscopic or open distal gastrectomy for gastric cancer, laparoscopic surgery does not increase intraoperative or postoperative complications, and has advantages of minimally invasiveness, fine operation, quicker recovery, and shorter hospital stay. Registry: this study was registered at clinicaltrials.gov in United States, with the registry number of NCT02246153.

Objective:To explore the application value of a novel ultrasonic scale in the evaluation of sub-massive pulmonary embolism (sub-PE).Methods:Retrospective analyses were conducted in 137 patients with acute pulmonary embolism confirmed by computed tomography pulmonary angiography (CTPA) in the second affiliated hospital of Harbin Medical University from September 2017 to June 2019. They were divided into experimental set (77 cases) and testing set(60 cases). According to the European Society of Cardiology (ESC) guidelines for pulmonary embolism in 2019, the patients were classified into sub-PE(71 cases) and small pulmonary embolism(small-PE, 66 cases). Parameters in the experimental set were screened by statistical methods to make an ultrasonic scale, and then the patients in the testing set were scored by the scale. ROC curve was plotted to calculate the diagnostic efficacy of the ultrasonic scale for sub-PE.Results:①The patients of sub-PE were older than small-PE patients [(61.57±1.45) years vs (56.31±1.59) years, P=0.016], but there was no significant difference between the two groups in other general data( P>0.05). ②Within the 77 pulmonary embolism patients in the experimental set, 41(53.25%) were classified as the sub-PE and 36(46.75%) as the small-PE. Compared with the small-PE group, right ventricular diameter, pulmonary artery trunk diameter, right ventricle/left ventricle ratio, tricuspid regurgitation velocity, the Tei index and the inferior vena cava diameter in the sub-PE group increased significantly ( P<0.05), and right ventricular wall motion amplitude, right atrium area rate, right ventricular area rate, tricuspid annulus systolic displacement, collapse rate of inferior vena cava and pulmonary artery blood flow acceleration time decreased significantly ( P<0.05); ③Fifteen ultrasonic parameters were used in the ultrasonic scale. The scale in sub-PE group of the testing set was significantly increased compared with that in small-PE group (11.63±3.87 vs 4.43±1.96, P<0.001). ROC showed that the AUC in diagnosing sub-PE by ultrasonic scale was 0.96. When the cut-off value was 6.5, the sensitivity and specificity were 90.00% and 83.33%, respectively. Conclusions:The novel ultrasonic scale can provide a comprehensive and feasible ultrasound imaging method for evaluation of sub-PE.

Objective:To observe the clinical efficiency, duration of action and adverse reactions of lip contour after local injection of type A botulinum toxin into the orbicularis oculi muscle.Methods:From March 2019 to June 2019, a total of 11 patients (6 males and 5 females, mean age 42.2 years) received superficial injection of botulinum toxin A in the orbicular muscle in our hospital. The change of lip thickness was assessed by Medicis lip fullness scale (MLFS) and the 3D structured light camera was used to collect and analyze the facial data. Pre- and post-treatment effects, duration of action and complications were evaluated.Results:Improvement of upper lip thickness was noted in 11 cases (100%). The average onset time after injection was 14.6 days and average effect maintenance time was 124.1 days. The height of the red lips ( Z=-2.940, P<0.05), the distance from the upper lip to the Ricketts line ( Z=-2.137, P<0.05) and nasolabial angle ( Z=-2.137, P<0.05) were significantly changed one month after the injection. No allergic reaction was observed, and the adverse reactions were mild and reversible. Conclusion:Local injection of botulinum toxin type A can achieve mild lip augmentation.
