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:A nationwide multi-center and large sample survey was conducted to compare the validity of the Mini International Neuropsychiatric Interview (Hypo-) Manic Episode with Mixed Features-DSM-5 Module (MINI-M) questionnaire and the Clinically Useful Depression Outcome Scale Supplemented with Questions for the DSM-5 Mixed Features Specifier (CUDOS-M) depression subscale in identifying mixed features in patients experiencing (hypo-) manic episodes.Methods:Using a convenience sampling method, 366 patients with bipolar disorder experiencing acute (hypo-) manic episodes who met the inclusion and exclusion criteria were recruited. The diagnosis of "with mixed features" was based on the DSM-5 criteria for mixed features. The predictive validity of the MINI-M questionnaire and the CUDOS-M depression subscale to screen mixed features was analyzed using the receiver operating characteristic (ROC) curve. Additionally, the difference in area under the ROC curve (AUC) between the two instruments was compared.Results:The AUC for the MINI-M questionnaire and the CUDOS-M depression subscale in screening mixed features were 0.79 (95 %CI=0.75-0.84) and 0.81 (95 %CI=0.77-0.86), respectively. There was no statistically significant difference in AUC between the two measurements ( Z=-1.19, P>0.05). Among patients with acute (hypo-) manic episodes, 45.9% (168/366) presented with mixed features according to the DSM-5 criteria, while the corresponding figures were 43.7% (160/366) using the MINI-M questionnaire (total score≥3) and 42.1% (154/366) using the CUDOS-M depression subscale (total score≥20). Screening results were comparable among the three measures. Conclusion:Mixed features are common among patients experiencing acute (hypo-) manic episodes. The MINI-M questionnaire and the CUDOS-M depression subscale demonstrate equivalent validity in identifying mixed features.

Objective To observe the effect of Bushen Gutai mixture on uterine blood supply of rat model of abortion induced by hydroxyurea tablets combined with mifepristone through PKA-CREB signal pathway and its mechanism of calming fetus.Methods 60 pregnant rats of SPF grade SD rats were prepared by closing cages at 2∶1.According to the order of pregnancy,60 pregnant rats were randomly divided into 6 groups with 10 rats in each group:Bushen Gutai mixture group(low,middle and high dose),normal pregnancy group,model group and Di qu progesterone group.On the 1st to 9th day of pregnancy,except the normal group,the pregnant rats in each group were gavaged with hydroxyurea tablets at 5∶00 pm every day(450 mg·kg-1),and at 10∶00 am on the 10th day of pregnancy.Mifepristone tablets were given by intragastric administration(4.0 mg·kg-1).At 9∶00 am every day from the 1st to 9th day of pregnancy,Bushen Gutai mixture was given to the low,middle and high dose groups(0.5,1.0,2.0 g·kg-1),didrone group(3.02 mg·kg-1),model group and normal pregnancy group with 0.9%normal saline.24 hours after the last administration of pentobarbital sodium(50 mg kg-1),all pregnant rats were killed by intraperitoneal injection of pentobarbital sodium,and the uterine decidual tissue of pregnant rats was bluntly isolated in sterile environment.Hematoxylin-eosin(HE)staining was used to observe the lumen diameter and wall thickness of spiral artery in uterine decidual tissue.Immunohistochemical staining(IHC)was used to detect the expression of vascular endothelial growth factor(VEGF)in decidual tissues.Western blot was used to detect the protein expression of phosphorylated protein kinase A,protein kinase A,phosphorylated cyclic adenosine monophosphate response element binding protein,Cyclic Adenosine monophosphate response element binding protein and aquaporin 5 in the decidua of pregnant rats.The apoptosis of decidual cells was detected by in situ end labeling(TUNEL)of DNA fragmentation.Results Compared with the model group,the wall thickness of spiral artery was higher than that in other groups(P<0.05),the lumen diameter was lower than that in other groups(P<0.05)and the expression of VEGF protein was lower than that of other groups(P<0.01).Compared with the model group,the apoptosis level of decidual cells in uterine decidua of abortive rats in high,middle and low dose groups of Bushen Gutai mixture and diqu progesterone group decreased in varying degrees.Bushen Gutai mixture can up-regulate the levels of p-PKA/PKA and p-CREB/CREB in uterine decidua(P<0.01)and promote the expression of AQP5 protein in uterine decidua of abortion rats(P<0.01).Conclusion Bushen Gutai mixture can improve uterine blood supply of aborted rats by activating PKA and CREB phosphorylation,up-regulating AQP5 expression,promoting physiological recasting of spiral artery and high expression of Vascular endothelial growth factor.

Objective:This study investigates the difference in the detection rate and symptomatology between ICD-10 and DSM-5 diagnostic criteria for bipolar disorder with mixed states.Methods:Based on the Phase Ⅰ (2012) and Phase Ⅱ (2021) databases of National Bipolar Mania Pathway Survey (BIPAS), patients with bipolar disorder were included. General demographic data, clinical characteristics, symptomatic phenotypes, and mixed characteristics were retrieved. The detection rates and symptomatic performances of patients with or without mixed states in Phase Ⅰ and Ⅱ were compared using the chi-square test.Results:For patients with mixed states, the detection rate during Phase Ⅱ (2021) using DSM-5 (18.79%, 199/1 059) criteria was significantly higher than that during Phase Ⅰ (2012) using ICD-10 (6.78%, 199/2 934; χ 2=125.05, P<0.001). Whether using ICD-10 or DSM-5 criteria, patients with mixed states had a significantly higher frequency of multiple symptomatic manifestations. Conclusion:The DSM-5 diagnostic criteria generate a high detection rate for bipolar disorder with mixed states. The clinical phenotypes of bipolar disorder with mixed states vary significantly using different diagnostic tools.

Objective: To analyze the follow-up and clinical effect of multidisciplinary treatment on the children with spinal muscular atrophy (SMA). Methods: The clinical data including nutritional status, respiratory function, bone health and motor function of 45 children with SMA who received multidisciplinary management 1-year follow-up in the Children's Hospital, Zhejiang University School of Medicine from July 2019 to October 2021 were retrospectively collected. Comparisons before and after management were performed using paired-samples t-test or Wilcoxon rank-sum test, etc. Results: The age of 45 patients (25 boys and 20 girls) was 50.4 (33.6, 84.0) months at the enrollment, with 6 cases of type 1, 22 cases of type 2, and 17 cases of type 3 respectively. After the multidisciplinary management, the cases of SMA patients with malnutrition decreased from 22 to 12 (P=0.030), the level of vitamin D were significantly increased ((45±17) vs. (48±14) nmol/L, t=-4.13, P<0.001). There was no significant difference in the forced vital capacity %pred, the forced expiratory volume at 1 second %pred, and the peak expiratory flow %pred ((76±19)% and (76±21)%, (81±18)% and (79±18)%, (81±21)% and (78±17)%; t=-0.24, 1.36, 1.21; all P>0.05). The Cobbs angle of scoliosis also improved significantly (8.0°(0°, 13.0°) vs. 10.0°(0°, 18.5°), Z=-3.01, P=0.003). The Hammersmith functional motor scale expanded scores of children with SMA type 2 and type 3 both showed significant elevation (11.0 (8.0, 18.0) vs. 11.0 (5.0, 18.5) scores, 44.0 (36.5, 53.0) vs. 44.0 (34.0, 51.5) scores, Z=2.44, 3.11, P=0.015, 0.002). Conclusion: Multidisciplinary management is beneficial for delaying the progression of the multi-system impairments of SMA patients, such as malnutrition, restrictive ventilation dysfunction and scoliosis.

Objective:To investigate the effect of lateral tibial periosteum distraction on diabetic foot and vasculitis foot.Methods:A retrospective analysis of 13 patients (16 feet) who received lateral tibial periosteal distraction between June 2019 and May 2020 were included in the study. 9 males and 4 females; aged 39-77 years (average 66 years); left foot 7 cases, right foot 9 cases. 5 cases were patients with diabetic foot, 1 case was diabetic foot with arteriosclerosis obliterans, 2 cases were thromboembolic vasculitis, and 5 cases were arteriosclerosis obliterans. The tibial periosteum was dissected and a distraction device was placed. In the 3 patients with foot ulcers, tibial periosteum distraction devices were placed on the severer side. The periosteal distraction began on the third day after surgery, about 0.75 mm/d, the adjustment was done usually in two weeks. Two weeks later, the stretch plate was removed surgically. The followings were evaluated: visual analogue scale (VAS) pain score, foot peripheral oxygen saturation, foot capillary filling test, lower extremity arterial CT angiography (CTA), etc.Results:All 13 patients were followed up for 2-12 weeks, with an average of 3.85 weeks. VAS pain score: the average pain score of 13 patients with preoperative foot pain was 5.31±1.84 (range, 2-9) points, and 2 weeks after surgery, the average value was 2.46±1.39 (range, 1-6) points with statistical significance ( t=6.124, P<0.001) ; peripheral foot oxygen saturation: the average preoperative blood oxygen saturation of 12 patients was 87.83%±14.83% (range, 50%-98%), 1 patient was not detected before surgery, and 2 weeks after operation, the average blood oxygen saturation was 92.33%±7.91% (range, 75%-99%). There was no significant difference between them ( t=1.124, P=0.285). The foot skin temperature of 10 patients was 35.68±0.85 ℃ (range, 34.00-36.60 ℃) before surgery and 36.23±0.46 ℃ (range, 35.50-36.90 ℃) after surgery, and the difference was statistically significant ( t=3.197, P=0.008) . Capillary filling test: 2 weeks after operation, the capillary filling response was significantly improved. All 13 patients had improved CTA of both lower extremity arteries before operation, and 11 patients had CTA taken back after two weeks of operation. Compared with preoperative CTA, new vascular network was found in the operation limb. In addition to 1 patient with thromboangiitis obliterans (mainly suffering from foot pain, no wound symptoms), 2 of 12 patients with heart failure, renal failure and other basic diseases did not heal, and the wounds of the other 10 patients had improved significantly 1 month later. Conclusion:Lateral tibia periosteum distraction can be used to treat chronic ischemic diseases of lower extremities with satisfactory postoperative results.

OBJECTIVE: To study the effect of pertussis vaccination on the clinical manifestations of infants and young children with pertussis. METHODS: A retrospective analysis was performed to investigate the differences in clinical manifestations and peripheral blood cell levels between pertussis children with different pertussis vaccination status. RESULTS: A total of 1 083 children with pertussisat at age of < 3 years were enrolled, with 551 children in the unvaccinated group and 532 in the vaccinated group. Of all the children, 392 had an age of onset of < 3 months (372 were unvaccinated and 20 were vaccinated) and 691 children had an age of onset of ≥ 3 months (179 were unvaccinated and 512 were vaccinated). Compared with the vaccinated group, the unvaccinated group had a longer length of hospital stay and a higher incidence rate of respiratory failure ( CONCLUSIONS Pertussis vaccination can reduce the incidence of severe pneumonia and respiratory failure and alleviate the severity of respiratory complications in infants and young children with pertussis.

Objective To measure the effects of 72 h-isolation and confinement (IC)with or without sleep deprivation (SD)on attention network functions and operation performance of manual controlled rendezvous and docking task. Methods Twelve healthy male volunteers were randomly divided into 4 groups of 3.The experiments were done by means of self-control and cross-over design. Two groups underwent 72 h IC without SD,and then recovered for 7 d.After that,they underwent 72 h IC with SD.Other 2 groups underwent the identical environments in the opposite order.The evaluation of attention network functions and the functional nuclear magnetic resonance examination of brain were conducted before and after isolation.The operation performance of manual controlled rendezvous and docking task was tested during isolation.Meanwhile, the functional magnetic resonance imaging (fMRI)technology was used to evaluate the autonomic activity in the brain region. Results ①The volunteers, average reaction time, accuracy and omission rates of the attention network function test in 72 h IC had insignificant differences as compared with those before the isolation (P>0.05).The 72 h IC and SD caused average reaction time and omission rate evidently increased (t=2 .505 ,2 .3 24,P<0.05 ).For average reaction time,the main effect of test condition was obvious (F=6.725,η2=0.657,P<0.05),so as the mutual effects of test time and test condition for omission rate (F=6.057,5.906,η2=0.612,0.601,P<0.05).For accuracy rates,all three effects were not obvious (P>0.05).②The fMRI data indicated that the spontaneous nervous activity in right frontal eye field was significantly weakened by IC and SD (t=6.580,P<0.05 ),but the activities in 3 clustering fields of right temporal lobe joint were significantly enhanced (t=6.726, 4.905,8.305,P<0.05).③As compared with those in IC condition,the volunteers, success rate of manual controlled rendezvous and docking task in IC plus SD condition was evidently decreased (χ2=9 .7 6 1 ,P<0.0 1 ),but the fuel consumption,pitch angle deviation and yaw angle deviation were significantly increased (t=3 .47 5 ,3 .1 6 1 ,3 .3 7 5 ,P<0.0 1 )and the docking time was significant shortened (t=2 .6 8 1 ,P<0.0 1 ). Conclusions 72 h IC and SD has negative effects on attention network function and operation performance of manual controlled rendezvous and docking task.Sleep deprivation would be the main factor.
