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.

Autologous ozonized blood transfusion(AOBT) is a therapy of re-transfusion of 100-200 mL of autologous blood after shaking and agitation with appropriate amount of oxygen-ozone in vitro. The oxidation of blood through the strong oxidation of ozone can enhance the non-specific immune response of the body, regulate the internal environment and promote health. This therapy has been increasingly applied in clinical practice, while no unified standard for the operation process in terms of ozone concentration, treatment frequency and treatment course had been established. This operation process of AOBT is primarily explored in order to standardize the operation process and ensure its safety and efficacy.

The syndrome of dampness stagnancy due to spleen deficiency (DSSD) is relatively common globally. Although the pathogenesis of DSSD remains unclear, evidence has suggested that the gut microbiota might play a significant role. Radix Astragali, used as both medicine and food, exerts the effects of tonifying spleen and qi. Astragalus polysaccharide (APS) comprises a macromolecule substance extracted from the dried root of Radix Astragali, which has many pharmacological functions. However, whether APS mitigates the immune disorders underlying the DSSD syndrome via regulating gut microbiota and the relevant mechanism remains unknown. Here, we used DSSD rats induced by high-fat and low-protein (HFLP) diet plus exhaustive swimming, and found that APS of moderate molecular weight increased the body weight gain and immune organ indexes, decreased the levels of interleukin-1β (IL-1β), IL-6, and endotoxin, and suppressed the Toll-like receptor 4/nuclear factor-‍κB (TLR4/NF-‍κB) pathway. Moreover, a total of 27 critical genera were significantly enriched according to the linear discriminant analysis effect size (LEfSe). APS increased the diversity of the gut microbiota and changed its composition, such as reducing the relative abundance of Pseudoflavonifractor and Paraprevotella, and increasing that of Parasutterella, Parabacteroides, Clostridium XIVb, Oscillibacter, Butyricicoccus, and Dorea. APS also elevated the contents of short-chain fatty acids (SCFAs). Furthermore, the correlation analysis indicated that 12 critical bacteria were related to the body weight gain and immune organ indexes. In general, our study demonstrated that APS ameliorated the immune disorders in DSSD rats via modulating their gut microbiota, especially for some bacteria involving immune and inflammatory response and SCFA production, as well as the TLR4/NF-κB pathway. This study provides an insight into the function of APS as a unique potential prebiotic through exerting systemic activities in treating DSSD.

Objective:To explore the construction and application of the standard process of thirst management for patients undergoing endonasal transsphenoidal surgery for pituitary adenomas.Methods:From June 2020 to October 2021, 160 patients with endonasal transsphenoidal surgery for pituitary adenomas who were admitted to the Neurosurgery Department of the First Affiliated Hospital of University of Science and Technology of China (Anhui Provincial Hospital) were selected by convenience sampling. The patients were randomly divided into test group and control group, 80 cases in each group. The control group implemented routine nursing to prevent postoperative thirst, while the test group established a standard process of thirst management and implemented thirst prevention and interventions according to the process. The thirst intensity, thirst pain and resting salivary flow rate between the two groups was compared.Results:The thirst intensity scores of patients in the test group at 2, 6 and 24 hours after operation were lower than those in the control group, with statistically significant differences ( Z=-8.696, -10.008, -4.305; P<0.01) . The score of thirst pain in the test group was lower than that in the control group, and the resting salivary flow rate at 6 and 24 hours after operation were higher than those in the control group, with statistically significant differences ( Z=-9.488, -4.124, -2.631; P<0.01) . Conclusions:The standard process of thirst management can reduce the postoperative thirst intensity of patients with pituitary adenomas surgery and improve their thirst feeling, which is worthy of clinical promotion.

Objective To investigate the clinical efficacy and safety of Danshu Capsule in the treatment of chronic cholecystitis and gallstones through a large-sample, multicenter, open-label real-world research. Methods A total of 9579 patients with chronic cholecystitis and/or gallstones who were treated in 329 hospitals of China from January 2017 to December 2019 were enrolled and divided into gallstones group with 1148 patients, chronic cholecystitis group with 5360 patients, and chronic cholecystitis+gallstones group with 3071 patients.All patients were treated with oral administration of Danshu Capsule at a frequency of 1-2 capsules/time, three times a day after meals, for 4 consecutive weeks.Abdominal pain, biliary dyspepsia, traditional Chinese medicine (TCM) syndromes, and imaging findings of the biliary system were recorded before and after treatment to evaluate the efficacy of medication, and adverse drug reactions were monitored to evaluate the safety of Danshu Capsule.The Wilcoxon signed-rank test was used for comparison of non-normally distributed continuous data before and after treatment, and the Wilcoxon rank-sum test was used for comparison between any two groups.The paired chi-square test was used for comparison of categorical data before and after treatment; the Kruskal-Wallis H method was used for comparison between multiple groups, and the Logistic regression analysis and the Nemenyi test was used for further comparison between two groups. Results After treatment with Danshu Capsule, all patients had significant reductions in the overall incidence rate of pain induced by lipid meal ( χ 2 =32.422, P < 0.001), the frequency, duration, and degree of pain ( Z =-1.985, -2.887, and-3.178, all P < 0.05), the symptom scores of abdominal distension, abdominal fullness, belching, and nausea (all P < 0.001), and the total symptom score of biliary dyspepsia ( Z =-4.128, P < 0.001);there were also significant reductions in the TCM syndrome scores of right upper quadrant pain, bitter taste, acid regurgitation, chest distress, abdominal distension, poor appetite, and heaviness of limbs (all P < 0.05) and a significant reduction in total TCM syndrome score ( Z =3.860, P < 0.001).Subgroup analysis showed that after treatment, the gallstones group, the chronic cholecystitis group, and the chronic cholecystitis+gallstones group had significant reductions in the degree, frequency, and duration of pain, the symptom score of biliary dyspepsia, and TCM syndrome score (all P < 0.05), as well as a significant reduction in the number of patients with pain induced by lipid meal ( P < 0.001).The chronic cholecystitis group had significantly greater reductions in the score of pain frequency, the score of pain duration, the score of pain degree compared with the other two groups (all P < 0.05).Ultrasound examination showed that after treatment, all patients had significant reductions in poor sound transmission of gallbladder, gallbladder wall thickness, incidence rate of gallbladder wall thickening or roughness, and the number and size of gallstones (all P < 0.05).Danshu Capsule showed an overall response rate of 74.75% in the treatment of gallbladder wall lesion and an overall response rate of 67.40% in the treatment of gallstones.A total of 84 patients reported adverse events, mainly gastrointestinal symptoms, and the overall incidence rate of adverse reactions was 0.87%. Conclusion Danshu Capsule can significantly alleviate the symptom of pain and improve the symptoms of biliary dyspepsia, TCM syndrome, and gallbladder imaging findings in patients with chronic cholecystitis and/or gallstones, with a low incidence rate of adverse reactions, and therefore, it is a safe and effective drug for the treatment of chronic cholecystitis and gallstones.

Objective:To study the predictive value of the amplitude-integrated electroencephalography (aEEG) within 6 hours and 3 days after birth and magnetic resonance imaging(MRI) on the adverse neurobehavioral development of asphyxiated preterm infants at the correction age of 6 months.Methods:From December 2017 to June 2019, 50 asphyxiated preterm infants who were delivered at the obstetrical department transferred to the division of neonatology in the Third Affiliated Hospital of Anhui Medical University were monitored by aEEG within 6 hours after birth, then once a day for at least 4 h. MRI was administered at 40 weeks of corrected age, neuromotor developmental function of the infants was assessed by the Geisel developmental diagnostic scale at 6 months of corrected age, then the infants were divided into good prognosis group and poor prognosis group according to the assessment results. SPSS 19.0 software was used for statistical analysis.The software of SPSS 19.0 was used to analyze the data.Independent sample t-test and χ 2 test were used to analyze the difference between the two groups.The relationship between aEEG grading and MRI, and their predictive value for adverse neurobehavioral development were analyzed at 6 months of corrected age. Results:The degree of white matter damage( H=24.896) and intracranical hemorrhage( H=29.245) of premature infants with different aEEG clinical grades were different (both P<0.01) on MRI. The sensitivity of aEEG within 6 hours and 3 days after birth on predicting poor prognosis was 96.2% and 97.8%, the specificity was 56.2% and 62.5%, the negative predictive value was 98.2% and 99.0%, the positive predictive value was 37.8% and 52.3%, the correct index was 52.4% and 60.3%, respectively. The aEEG was combined with MRI, the sensitivity (90.0%, 97.0%), specificity (89.0%, 99.0%), negative predictive value (99.2%, 99.5%), positive predictive value (80.6%, 88.5%), and correct index (79%, 96%) were all improved. Conclusion:The combination of aEEG grading and MRI can improve the prognostic value on neurodevelopmental prognosis, and provide a better evaluation basis for clinical follow-up and intervention of asphyxiated premature infants with brain injury.

Objective:To analyze the clinical characteristics of gastrointestinal symptoms and liver function injury in patients with coronavirus disease 2019 (COVID-19).Methods:From January 23, 2020 to February 29, 2020, the medical records of 251 patients with COVID-19 admitted to the West Campus of the Union Hospital, Tongji Medical College of Huazhong University of Science and Technology, were collected. The proportion of the patients with gastrointestinal symptoms including anorexia, nausea and vomiting, diarrhea and abdominal pain were analyzed respectively. The patients were divided into common type (76 cases), severe type (65 cases) and critical type (110 cases). The incidence of liver function injury and the changes of liver function parameters such as total bilirubin (TBil), direct bilirubin (DBil), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), γ-glutamyl transpeptidase (GGT), lactate dehydrogenase (LDH), albumin and globulin of the patients with different clinical types and with or without gastrointestinal symptoms were analyzed. Mann-Whitney U test, Chi square test and Fisher′s exact test were used for statistical analysis. Results:The main gastrointestinal symptoms of patients with COVID-19 were anorexia (33.9%, 85/251), diarrhea (12.0%, 30/251), nausea and vomiting (7.6%, 19/251) and abdominal pain (1.2%, 3/251). 143 patients (57.0%) had liver function injury, the rate of liver function injury in critical type patients was 75.5% (83/110), which was higher than that of common type patients (40.8%, 31/76) and severe type patients (44.6%, 29/65), and the differences were statistically significant ( χ2=22.765 and 16.865, both P<0.01). There was no significant difference in the proportion of patients with liver function injury between common type and severe type patients ( P>0.05). There was no statistically significant difference in the proportion of liver function injury between patients with gastrointestinal symptoms and those without gastrointestinal symptoms (57.8%(67/116) vs. 56.3%(76/135), P>0.05). The median values of TBil, DBil, ALT, AST, ALP, GGT, LDH and globulin level of critical type patients were 13.5 μmol/L, 4.9 μmol/L, 44.5 U/L, 50.0 U/L, 64.0 U/L, 41.0 U/L, 527.0 U/L and 33.6 g/L respectively. The proportions of critical type patients with TBil level >34.2 μmol/L, DBil level>13.6 μmol/L, ALT level>80 U/L and AST level>80 U/L were 7.3% (8/110), 7.3% (8/110), 17.3% (19/110) and 17.3% (19/110), respectively. These results were all higher than those of common type patients (9.5 μmol/L, 2.9 μmol/L, 28.5 U/L, 28.5 U/L, 54.0 U/L, 25.5 U/L, 225.5 U/L, 30.1 g/L, 0, 0, 6.6% (5/76) and 2.6% (2/76) ) and severe type patients (10.4 μmol/L, 3.4 μmol/L, 30.0 U/L, 31.0 U/L, 49.0 U/L, 25.0 U/L, 284.0 U/L, 30.7 g/L, 0, 0, 6.2% (4/65) and 1.5% (1/65)), and the differences were statistically significant ( Z=-4.264, -5.507, -4.000, -6.558, -3.112, -4.333, -4.858, -3.873, Fisher′s exact test, Fisher′s exact test, χ2=4.574, 9.620; Z=-3.060, -3.850, -3.923, -5.005, -9.495, -7.651, -3.853, -2.725, Fisher′s exact test, Fisher′s exact test, χ2=4.425, 10.169; all P<0.01). The median values of pre-albumin level, albumin level and the albumin to globulin ratio of critical type patients were 85.3 g/L, 28.2 g/L and 0.8, which were all lower than those of common type patients (157.3 g/L, 32.3 g/L and 1.1, respectively) and severe type patients (133.6 g/L, 31.6 g/L and 1.1, respectively), and the differences were statistically significant ( Z=-6.631, -3.647, -4.924, -4.503, -5.283 and -3.903, all P<0.01). The median albumin level of patients with diarrhea was lower than that of patients without diarrhea (28.2 g/L vs. 30.5 g/L), the proportion of diarrhea patients whose TBil level >20.0 to 34.2 μmol/L was higher than that of patients without diarrhea (70.0%, 21/30 vs. 10.9%, 24/221), and the differences were statistically significant ( Z=-2.182, χ2 =62.788; both P<0.05). Conclusions:Anorexia is the most common digestive symptom in COVID-19 patients, and the incidences of abdominal pain is low. The incidence of liver function injury of critical type patients is high. There is no significant correlation between gastrointestinal symptoms and liver function injury, and patients with diarrhea have lower albumin levels.

Objectives: To explore the association between the polymorphism of persistent obesity and genetic variations in the LEP (human leptin gene, LEP) and LEPR (leptin receptor gene, LEPR) genes and different molecular subtypes of breast cancer. Methods: All 703 female patients of breast cancer diagnosed by histopathology in the Sichuan Cancer Hospital or the West China Hospital, excluding patients with metastatic breast cancer or mental disease, were selected as cases from April 2014 to May 2015. At the same time, 805 healthy women received physical examination in medical examination center of Sichuan People Hospital or Shuangliu maternal and child health care hospital, excluding those with therioma, breast disease, and mental disease, were enrolled in control group. A uniform questionnaire was used to collect general information including demographic characteristic, reproductive history height, weight, and so on. And the obesity status in recent 10 years was judged. Time of Flight Mass Spectrometer was used to determine the genotypes of LEP rs7799039, LEPR rs1137100 and LEPR rs1137101, while the multinomial logistic regression analysis was conducted to estimate the effect of risk factors related to breast cancer in different molecular subtypes; and then, the association between polymorphism of persistent obesity, the LEP, LEPR genes and breast cancer of different molecular subtypes was analyzed by binary logistic regression models. Results: The average age of controls was (48.98±8.83) years old, while the age of cases of TNBC, Luminal A, Luminal B, and HER-2+ were (51.43±11.33), (49.94±10.10), (49.73±9.38), (50.50±9.04) years old, respectively. The frequency of genotype LEP rs7799039, LEPR rs1137100 and LEPR rs1137101 in control group was separately 74.8%(1 157/1 546), 83.6%(1 339/1 602) and 88.4%(1 416/1 602); while 77.6% (1 074/1 384), 82.4% (1 155/1 402) and 87.9% (1 232/1 402) respectively in case group. Compared with non-persistent obesity subjects, the persistent obesity ones showed an increased risk in TNBC (OR=3.58, 95%CI: 1.90-6.72), Luminal A (OR=2.65, 95%CI: 1.35-5.21) and Luminal B (OR=1.90, 95%CI: 1.26-2.89) breast cancer. LEP rs7799039-AA was relevant with the upward risk of Luminal B independently (OR=1.30, 95%CI: 1.00-1.69). Besides, persistent obesity was found to have a combined effect on Luminal B (β=3.34, 95% CI: 1.00-11.12) with LEPR rs1137101-GG. Conclusion Persistent obesity could increase the potential risk of TNBC, Luminal A and Luminal B breast cancer. Women who were suffered from persistent obesity with a genotype of LEPR rs1137101-GG were more susceptible to Luminal B breast cancer.

Objective To establish a reliable approach for quantification of colony forming unit(CFU)of Mycobac-terium tuberculosis (M.tb)by measuring optical density(OD).Methods M.tb suspension H37Ra was prepared using low-power ultrasonic or glass bead beating methods,and was two-fold serially diluted,OD at 600nm (OD600)of each dilution ratio was measured respectively,OD600 and dilution curve were analyzed to determine the optimum approach for preparing bacterial suspension,linear range of OD600,as well as linear relationship between OD600 and CFU.Results OD600 was 0.1 -0.6,linear regression analysis of OD600 and dilution ratio within linear range revealed that correlation coefficient (R2 )of glass bead beating and low-power ultrasonic methods were 0.98 and 1 .00 respectively,both presented a good correlation,low-power ultrasonic method was better than glass bead beat-ing method,bacterial suspension dispersed more evenly.Linear regression analysis results of OD600 and CFU val-ues showed that the regression equation of glass bead beating method and low-power ultrasonic method were CFU=2.35×107 ×OD600+4.42×105 and CFU=3.26×107 ×OD600+6.89×105 respectively.Conclusion Low-power ultrasonic method is a good method for preparation of M.tb suspension,combined the measurement of OD600 value, it can be a reliable and rapid method for quantitative analysis of M.tb.
