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 influencing factors of pregnancy-induced hypertensive disorders in pregnancy (HDP) with organ or system impairment in pregnant women, and to analyze and compare the differences of HDP subtypes in different regions of China. Methods: A total of 27 680 pregnant women with HDP with complete data from 161 hospitals in 24 provinces, autonomous regions and municipalities were retrospectively collected from January 1, 2018 to December 31, 2018. According to their clinical manifestations, they were divided into hypertension group [a total of 10 308 cases, including 8 250 cases of gestational hypertension (GH), 2 058 cases of chronic hypertension during pregnancy] and hypertension with organ or system impairment group [17 372 cases, including 14 590 cases of pre-eclampsia (PE), 137 cases of eclampsia, 2 645 cases of chronic hypertension with PE]. The subtype distribution of HDP in East China (6 136 cases), North China (4 821 cases), Central China (3 502 cases), South China (8 371 cases), Northeast China (1 456 cases), Southwest China (2 158 cases) and Northwest China (1 236 cases) were analyzed. By comparing the differences of HDP subtypes and related risk factors in different regions, regional analysis of the risk factors of HDP pregnant women with organ or system impairment was conducted. Results: (1) The proportions of HDP pregnant women with organ or system impairment in Northeast China (79.05%, 1 151/1 456), Central China (68.42%, 2 396/3 502) and Northwest China (69.34%, 857/1 236) were higher than the national average (62.76%, 17 372/27 680); the proportions in North China (59.18%, 2 853/4 821), East China (60.85%, 3 734/6 136) and South China (59.56%, 4 986/8 371) were lower than the national average, and the differences were statistically significant (all P<0.05). (2) Univariate analysis showed that the proportions of primiparas, non-Han, non-urban household registration, irregular prenatal examination and PE history in the hypertension with organ or system impairment group were higher than those in the hypertension group, and the differences were statistically significant (all P<0.05). Multivariate logistic regression analysis showed that primiparas, non-Han, non-urban household registration, irregular prenatal examination and PE history were independent risk factors for HDP pregnant women with organ or system impairment (all P<0.05). (3) Primipara: the rates of primipara in Northeast China, North China and Southwest China were higher than the national average level, while those in South China, Central China and Northwest China were lower than the national average level. Non-Han nationality: the rates of non-Han nationality in Northeast China, North China and Northwest China were higher than the national average, while those in East China, South China and Central China were lower than the national average. Non-urban household registration: the rates of non-urban household registration in Northeast China, North China, and Southwest China were lower than the national average, while those in East China, Central China were higher than the national average. Irregular prenatal examination: the rates of irregular prenatal examination in North China, South China and Southwest regions were lower than the national average level, while those in Northeast China, Central China and Northwest China were higher than the national average level. History of PE: the incidence rates of PE in Northeast China, North China, South China and Southwest China were lower than the national average level, while those in Central China and Northwest China were higher than the national average level. Conclusions: Primiparas, non-Han, non-urban household registration, irregular prenatal examination, and PE history are risk factors for HDP pregnant women with organ or system impairment. Patients in Northeast, Central and Northwest China have more risk factors, and are more likely to be accompanied by organ or system function damage. It is important to strengthen the management of pregnant women and reduce the occurrence of HDP.

Coptidis Rhizoma, as a bulk medicinal material, is in great demand in clinical practice. Its quality is uneven in the market due to the mixture of genuine, counterfeit and adulterants. Therefore, it is particularly important to establish a quality control system for Coptidis Rhizoma. Based on the concept of Chinese medicine quality marker(Q-marker), the potential quality markers of Coptidis Rhizoma were analyzed and predicted from the perspective of chemistry and pharmacology. The sources of the Q-markers of Coptidis Rhizoma were identified by literature retrieval. The potential Q-markers were then screened through the visualization of the "components-targets-pathways" network. High performance liquid chromatography(HPLC) was used to establish a multi-indicator qualitative and quantitative control method featuring fingerprints for 10 batches of Coptidis Rhizoma. A supervised mode of orthogonality partial least squares method-discriminant analysis(OPLS-DA) was used to screen the main marker components that caused differences between groups. The literature review results showed that the alkaloids were the main source of Coptidis Rhizoma Q-markers.The fingerprints of 13 common peaks were successfully established, and berberine, palmatine, berberine and epiberberine were selected as Q-markers of Coptidis Rhizoma, and their contents were determined.Based on the concept of the Q-marker of traditional Chinese medicine, the four components can be selected as the Q-marker of Coptidis Rhizoma after comprehensive consideration. The results of this study are not only conducive to the quality evaluation of Coptidis Rhizoma on the market, but also provide a reference for the overall quality control of Coptidis Rhizoma and lay foundation for the future exploration of the mechanism of Coptidis Rhizoma.

Objective:To explore the nutritional status and influencing factors among children with disabilities in developed areas. Methods:From December, 2019 to January, 2020, and August to September, 2020, a total of 480 caregivers of children with disabilities aged two to 18 years in Shanghai were investigated their heights and weights, and the body mass index (BMI) was calculated. The influencing factors were analyzed from the dimensions of children's personal, family and social characteristics based on the Ecological System Theory. Chi-square test and binary Logistic regression model were used to analyze the influencing factors associated with the nutritional status of children with disabilities. Results:The prevalence of thinness, overweight and obesity in 480 children was 23.75%, 13.54% and 13.33%, respectively. Multivariate Logistic regression analysis showed that potato intake (OR = 0.420, 95%CI 0.197 to 0.893, P < 0.05) and caregivers' perception of child's weight (OR _underweight = 4.188, 95%CI 1.488 to 11.787, P < 0.01) were associated with children's thinness. Types of disability (OR _autism= 0.142, 95%CI 0.034 to 0.591, P < 0.01), the role of caregiver (OR _father= 5.519, 95%CI 1.110 to 27.440, P < 0.05), and caregivers' perception of the child's weight (OR _overweight = 5.669, 95%CI 1.112 to 28.903, P < 0.05) were associated with children's overweight/obesity. Conclusion:The prevalence of malnutrition among children with disabilities in Shanghai is higher than those typically-developing, especially thinness and obesity. The nutritional status is greatly affected by the type of disability, dietary intake and family characteristics.

Objective:To explore the quality of life of caregivers of children with disabilities and its influencing factors. Methods:From December, 2019 to January, 2020, and August to September, 2020, a total of 496 family caregivers of children with disabilities were surveyed in Shanghai. The 12-item Short-form Health Survey (SF-12) was used to measure the quality of life of 496 caregivers, and multiple linear regression was performed to analyze the related factors. Results:The score of physical component summary (PCS) of caregivers was (51.67±8.11), and the score of mental component summary (MCS) was (42.10±12.66). The scores of PCS were lower in caregivers with children aged 6 to 18 years (B = -1.783, 95%CI -3.279 to -0.287, P = 0.020), children with emotional instability (B = 2.719, 95%CI 1.254 to 4.184, P < 0.001), female caregivers (B = -3.765, 95%CI -6.578 to -0.953, P = 0.009), and caregivers who were relatively dissatisfied with the policy (B = 1.973, 95%CI 0.367 to 3.578, P = 0.016); and were higher in caregivers with children with speech disabilities (B = 3.463, 95%CI 0.053 to 6.873, P = 0.047). The types of disabilities of children (B_hearing = 9.465, 95%CI 5.107 to 13.823, P < 0.001; B_undetermined = 5.999, 95%CI 1.558 to 10.441, P = 0.008), playmates of children (B = 2.626, 95%CI 0.352 to 4.901, P = 0.024), education level of caregivers (B_{high middle school} = -4.701, 95%CI -8.028 to -1.374, P = 0.006; B_{high school} = -3.610, 95%CI -6.604 to -0.615, P = 0.018), family size (B = 2.616, 95%CI 0.479 to 4.753, P = 0.017) and per capita monthly income (B _{< 5000 Yuan}= -6.572, 95%CI -9.136 to -4.008, P < 0.001; B_{5000 to < 10000 Yuan} = -4.932, 95%CI -7.544 to -2.319, P < 0.001) were associated with the scores of MCS. Conclusion:The quality of life, especially the mental health, of caregivers of children with disabilities is poor. The influencing factors cover multiple dimensions such as caregivers, children, family and social environment.

Objective:To investigate the clinical features and prognosis of extranodal nasal-type NK/T-cell lymphoma of the extra-upper aerodigestive tract (extra-UADT NKTCL).Methods:The clinical data of 159 patients with extra-UADT NKTCL from the China Lymphoma Collaborative Group (CLCG) database between November 2001 and December 2015 were retrospectively analyzed. Kaplan-Meier survival analysis and Log-rank test were used to evaluate the prognosis. The Cox regression model is used for multi-factor analysis.Results:Extra-UADT NKTCL commonly occurs in skin and soft tissues (106/159, 66.7%) and gastrointestinal tract (31/159, 19.5%). The incidences of elevated lactate dehydrogenase (LDH) and Ann Arbor Ⅲ~Ⅳ stage were 47.8% (76/159) and 64.2% (102/159), respectively. The 3-year overall survival (OS) and progression-free survival (PFS) rates were 43.6% and 27.9%, respectively. The corresponding OS rates of primary skin/soft tissue site and gastrointestinal tract site were 41.0% and 59.4% ( P=0.281), while the PFS rates were 24.8% and 48.3%, respectively ( P=0.109). Combined modality treatment improved the 3-year OS of all the patients (58.4% vs 33.9%, P=0.001) and 3-year PFS (40.7% vs 20.7%, P=0.008) when compared with chemotherapy alone. LDH elevation, Ann Arbor synthesising and ≥2 junction external bits were intrusive as independent risk factors for total survival ( P<0.05), LDH elevation and ≥2 junction outer bits were intrusive as independent risk factors for progressionless survival( P<0.05). The distant extranodal dissemination was the primary failure patterns. Conclusions:Extra-UADT NKTCL appears to have distinct clinical characteristics and poor outcome. Compared with chemotherapy alone, combined modality treatment may improve the prognosis of patients with extra-UADT NKTCL.

Objective:To evaluate the prognosis and determine the failure patterns after radiotherapy for low-risk early-stage patients with extranodal NK/T-cell lymphoma, nasal-type (ENKTCL).Methods:A total of 557 patients from 2000—2015 with low-risk early-stage ENKTCL who received radiotherapy (RT) with or without chemotherapy (CT) from China Lymphoma Collaborative Group were retrospectively reviewed. Among them, 427 patients received combined modality therapy, whereas 130 patients received RT alone. Survivals were calculated by Kaplan-Meier method and compared with Log-rank test. Overall survival (OS) was compared with age and sex-matched general Chinese population using expected survival and standardized mortality ratio (SMR). Cox stepwise regression model was used for multivariate analysis.Results:The 5-year OS and progression-free survival (PFS) were 87.2% and 77.2%. The SMR was 3.59 ( P<0.001) at 1 year after treatment, whereas it was 1.50 at 4 years after treatment, without significant difference between ENKTCL group and country-matched general population ( P=0.146). Compared with RT alone, CMT did not result in significantly superior 5-year OS (87.0% vs 87.4%, P=0.961) or PFS (76.1% vs 80.7%, P=0.129). Local failure (11.5%, 64/557) and distant failure (10.8%, 60/557) were the main failure modes, while regional failure was rare (2.9%, 16/557). The 5-year locoregional control rate (LRC) was 87.2% for the whole group, with 89.5% for ≥50 Gy versus 73.7% for <50 Gy ( P<0.001). Radiotherapy dose was an independent factor affecting LRC( P<0.05). Conclusions:Radiotherapy achieves a favorable prognosis in patients with low-risk early-stage ENKTCL. The incidence of either locoregional or distant failure is low. Radiation dose still is an important prognostic factor for LRC.

Objective Whether the Ubi-p63E gene regulates spermatogenesis and tumorigenesis remains unclear. This study aimed to explore the regulatory effect of Ubi-p63E on germline stem cells (GSC) in the GSC niche of the Drosophila testis. Methods We used the UAS-Gal4 system for knockdown of the Ubi-p63E gene in the specific GSCs of the Drosophila testis and divided the male flies for this experiment into three groups: control (wild-type W1118 flies), nos>Ubi-p63E RNAi (knockdown of the Ubi-p63E gene in the early germ cells), and tj>Ubi-p63E RNAi (knockdown of the Ubi-p63E gene in the cystoblasts). We determined the fertility rate of the flies by fertility tests and examined the effect of Ubi-p63E on the Drosophila testis in the GSC niche by immunofluorescence staining. Results Fertility tests manifested a significantly lower rate of fertility in the nos>Ubi-p63E RNAi and tj>Ubi-p63E RNAi groups than in the control (0.00% and 4.12% vs 97.26%, P < 0.01). Morphologically abnormal testes were observed in the nos>Ubi-p63E RNAi and tj>Ubi-p63E RNAi groups, only 22.77% and 18.86% as long as the testes of the control flies. Immunofluorescence staining revealed no morphologically normal testes in the tj>Ubi-p63E RNAi group, but quite a few masses of abnormal cells, and mostly Vasa-positive cells. Conclusion The Ubi-p63E gene affects the self-renewal ability of GSCs in the GSC niche of the Drosophila testis as well as the differentiation of GSCs via cystoblasts, and consequently leads to the formation of germ cell tumors.
