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.

Abstract: Objective　To evaluate the value and significance of rifampicin-resistant real-time fluorescence quantitative nucleic acid amplification detection technology (GeneXpert MTB/RIF) in the diagnosis of pulmonary tuberculosis. 　　Methods　The clinical data of 228 patients with suspected pulmonary tuberculosis, who admitted to Hebei Chest Hospital from January 2018 to December 2019, were analyzed retrospectively. The sputum was collected for GeneXpert MTB/RIF, sandwich cup liquid-based bacterial acid-fast staining smear microscopy (referred to as “sandwich cup method”) and Loop-Mediated isothermal amplification (referred to as “LAMP method”) and the results were statistically analyzed by SPSS 17.0 software. Results　Among the 228 patients with suspected cases, 200 cases were clinically diagnosed as pulmonary tuberculosis and 28 were non-tuberculosis. The positive detection rate of GeneXpert MTB/RIF (81.0%, 162/200) was significantly higher than that of sandwich cup method (62.5%, 125/200) and LAMP method (72.5%,145/200) (χ2=16.885, 4.049, P<0.05). Taking clinical diagnosis as gold standard, the sensitivity of GeneXpert MTB/RIF (80.00%,160/200) was significantly higher than that of sandwich cup method (60.00%, 120/200) and LAMP method (70.50%, 141/200) (χ2=19.048, 4.846, P<0.05). The diagnostic consistency of GeneXpert MTB/RIF (K=0.73) was higher than that of sandwich cup method (K=0.39) and LAMP method (K=0.56). Conclusions The GeneXpert MTB/RIF detection method is rapid and simple, and can diagnose pulmonary tuberculosis rapidly and simultaneously detect rifampicin resistance of Mycobacterium tuberculosis with high sensitivity. It has high clinical value for early diagnosis of pulmonary tuberculosis and guidance of treatment in general and specialized hospitals.

Objective:To investigate the prevalence and risk factors of hypertensive retinopathy (HRP) in a non-diabetic population over 30 years old during routine health examinations.Methods:This was a cross-sectional study of a non-diabetic population over 30 years of age. The study was conducted during routine health examinations at the Tongren Hospital, Beijing, from January to December 2020. Fundus photographs were taken, and data including medical history, height, weight, and blood pressure were collected. Routine laboratory examinations were performed. The study population was divided into hypertension, transient hypertension, and non-hypertension groups. The prevalence of HRP was compared among the three groups. OR and 95% CI of HRP risk factors was estimated by binary logistic regression, adjusted for age and gender. Results:The prevalence of HRP was 4.3% in the non-diabetic population over 30 years old. Adjusted for age, gender, and systolic blood pressure, the prevalence of HRP in hypertension and transient hypertension groups, was both higher than in the non-hypertension group [ OR(95% CI) of 3.11(2.25-4.30) and 1.72(1.21-2.45), respectively]. The proportion of grade 1-2 HRP was higher (76.2%). There was no significant difference in the prevalence of grade 3 HRP among the three groups. Adjusted for age and gender, systolic blood pressure and creatinine clearance rate were independent risk factors for HRP in the hypertension group [ OR(95% CI): 1.22(1.01-1.48) and 1.66(1.12-2.46)] and transient hypertension group [ OR(95% CI): 1.48(1.10-2.06) and 1.95(1.03-3.46)]. SBP and DBP were independent risk factors for HRP in the non-hypertension group [ OR(95% CI): 1.68(1.07-2.63) and 1.61(1.06-2.44)]. Conclusions:There was a high prevalence of HRP among the non-diabetic population over the age of 30 and there was still relatively high risk of grade 3 HRP among the normotensive population.

OBJECTIVES: To investigate the incidence of extrauterine growth retardation (EUGR) and its risk factors in very preterm infants (VPIs) during hospitalization in China. METHODS: A prospective multicenter study was performed on the medical data of 2 514 VPIs who were hospitalized in the department of neonatology in 28 hospitals from 7 areas of China between September 2019 and December 2020. According to the presence or absence of EUGR based on the evaluation of body weight at the corrected gestational age of 36 weeks or at discharge, the VPIs were classified to two groups: EUGR group (n=1 189) and non-EUGR (n=1 325). The clinical features were compared between the two groups, and the incidence of EUGR and risk factors for EUGR were examined. RESULTS: The incidence of EUGR was 47.30% (1 189/2 514) evaluated by weight. The multivariate logistic regression analysis showed that higher weight growth velocity after regaining birth weight and higher cumulative calorie intake during the first week of hospitalization were protective factors against EUGR (P<0.05), while small-for-gestational-age birth, prolonged time to the initiation of total enteral feeding, prolonged cumulative fasting time, lower breast milk intake before starting human milk fortifiers, prolonged time to the initiation of full fortified feeding, and moderate-to-severe bronchopulmonary dysplasia were risk factors for EUGR (P<0.05). CONCLUSIONS It is crucial to reduce the incidence of EUGR by achieving total enteral feeding as early as possible, strengthening breastfeeding, increasing calorie intake in the first week after birth, improving the velocity of weight gain, and preventing moderate-severe bronchopulmonary dysplasia in VPIs.

Objective:To analyze the risk factors of bronchopulmonary dysplasia(BPD)in very preterm infants(VPI), and to provide scientific basis for the prevention and treatment of BPD in VPI.Methods:A prospective multicenter study was designed to collect the clinical data of VPI in department of neonatology of 28 hospitals in 7 regions from September 2019 to December 2020.According to the continuous oxygen dependence at 28 days after birth, VPI were divided into non BPD group and BPD group, and the risk factors of BPD in VPI were analyzed.Results:A total of 2 514 cases of VPI including 1 364 cases without BPD and 1 150 cases with BPD were enrolled.The incidence of BPD was 45.7%.The smaller the gestational age and weight, the higher the incidence of BPD( P<0.001). Compared with non BPD group, the average birth age, weight and cesarean section rate in BPD group were lower, and the incidence of male infants, small for gestational age and 5-minute apgar score≤7 were higher( P<0.01). In BPD group, the incidences of neonatal respiratory distress syndrome(NRDS), hemodynamically significant patent ductus arteriosus, retinopathy of prematurity, feeding intolerance, extrauterine growth restriction, grade Ⅲ~Ⅳ intracranial hemorrhage, anemia, early-onset and late-onset sepsis, nosocomial infection, parenteral nutrition-associated cholestasis were higher( P<0.05), the use of pulmonary surfactant(PS), postnatal hormone exposure, anemia and blood transfusion were also higher, and the time of invasive and non-invasive mechanical ventilation, oxygen use and total hospital stay were longer( P<0.001). The time of starting enteral nutrition, cumulative fasting days, days of reaching total enteral nutrition, days of continuous parenteral nutrition, days of reaching 110 kcal/(kg·d) total calorie, days of reaching 110 kcal/(kg·d) oral calorie were longer and the breastfeeding rate was lower in BPD group than those in non BPD group( P<0.001). The cumulative doses of amino acid and fat emulsion during the first week of hospitalization were higher in BPD group( P<0.001). Multivariate Logistic regression analysis showed that NRDS, invasive mechanical ventilation, age of reaching total enteral nutrition, anemia and blood transfusion were the independent risk factors for BPD in VPI, and older gestational age was the protective factor for BPD. Conclusion:Strengthening perinatal management, avoiding premature delivery and severe NRDS, shortening the time of invasive mechanical ventilation, paying attention to enteral nutrition management, reaching whole intestinal feeding as soon as possible, and strictly mastering the indications of blood transfusion are very important to reduce the incidence of BPD in VPI.

Colorectal cancer (CRC) is one of the most prevalent, most lethal cancers in the world. Increasing evidence suggests that the intestinal microbiota is closely related to the pathogenesis and prognosis of CRC. The normal microbiota plays an essential role in maintaining gut barrier function and the immune microenvironment. Recent studies have identified carcinogenic bacteria such as enterotoxigenic Bacteroides fragilis (ETBF) and Streptococcus gallolyticus (S. gallolyticus), as well as protective bacterial such as Akkermansia muciniphila (A. muciniphila), as potential targets of CRC treatment. Gut microbiota modulation aims to restore gut dysbiosis, regulate the intestinal immune system and prevent from pathogen invasion, all of which are beneficial for CRC prevention and prognosis. The utility of probiotics, prebiotics, postbiotics, fecal microbiota transplantation and dietary inventions to treat CRC makes them novel microbe-based management tools. In this review, we describe the mechanisms involved in bacteria-derived colorectal carcinogenesis and summarized novel bacteria-related therapies for CRC. In summary, we hope to facilitate clinical applications of intestinal bacteria for preventing and treating CRC.

Objective:To study the differences in genetic relationship， shape， size， and flavonoid content between traditional and nontraditional medicinal varieties of Citri Reticulatae Semen produced in Sichuan province as well as their equivalence. Method:Six batches of traditional medicinal Citri Reticulatae Semen （Citrus reticulata 'Dahongpao'） and 23 batches of nontraditional medicinal varieties were collected， and their genetic relationship was explored using sequence-related amplified polymorphism （SRAP） markers. Following the observation of their shapes and sizes under a stereomicroscope， the contents of naringin， hesperidin， and neohesperidin were measured by high performance liquid chromatography （HPLC）. SIMCA 14.1 software was used for cluster analysis of their shapes， sizes， and flavonoid contents， thus figuring out the similarities between the traditional and nontraditional medicinal varieties in character， size， and chemical components. Result:SRAP markers-based genetic relationship analysis effectively distinguished different Citri Reticulatae Semen varieties from each other. Some samples collected from the same or adjacent places exhibited a close genetic relationship and they shared high similarities in shape， size， and flavonoid content. However， the traditional medicinal Citri Reticulatae Semen was still quite different from most nontraditional medicinal varieties. Conclusion:The analysis of differences in genetic materials， appearance， character， and active ingredient content between the traditional and nontraditional medicinal varieties revealed that the equivalence of C. reticulata 'Ponkan' samples from some regions with the traditional medicinal variety was the largest， enabling them to be considered as the emerging medicinal variety.
