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.

To study the efficacy and compliance analysis of pollen allergen drops in the treatment of allergic rhinitis. The method of single-center controlled was used to analyze the dates' results. From July 2021 to September 2021, 80 patients with seasonal allergic rhinitis were referred to the clinic of otorhinolaryngology in First Hospital of Shanxi Medical University.40 patients received sublingual immunotherapy (SLIT group), and the other 40 patients received symptomatic drug treatment as the control group. The total rhinoconjunctivitis symptom score (TRSS), the visual analogue scale(VAS), total medication score (TMS) and combined scores of medication and rhinoconjunctivitis symptoms (CSMRS) of the patient before the start of the treatment and after the first year of the treatment were compared to assess the efficacy of sublingual immunotherapy of Artemisia pollen. Follow the shedding during the study, the safety of the drug and the causes for compliance analysis were analyzed and recorded. The results of comparison with TRSS, VAS, TMS and CSMRS in two groups in the period of pretherapy were as follows: TRSS(12.393±3.023, 12.450±3.029, t=-0.077, P=0.939), VAS(8.357±1.026, 8.400±0.982, t=-0.173, P=0.862), TMS(3.214±0.568, 3.175±0.501, t=0.301, P=0.764), CSMRS (5.286±0.680, 5.253±0.677, t=0.199, P=0.843), there was no significant difference (P>0.05); lower observed symptom scores were got in the post-treatment pollen peak SLIT group compared to the control group, TRSS(3.964±1.551, 7.750±2.169, t=-7.918, P<0.05), VAS(2.893±0.956, 5.175±1.481, t=-8.286, P<0.05), TMS (1.821±0.863, 3.175±0.501, t=-8.163, P<0.05), CSMRS (2.489±0.921, 4.468±0.601, t=-10.723, P<0.05), and the differences between the groups were statistically significant (P<0.05); the SLIT group significantly reduced all symptom scores at the first peak compared to the starting, TRSS(12.393±3.023, 3.964±1.551, t=20.576, P<0.05), VAS (8.357±1.026, 2.893±0.956, t=30.070, P<0.05), TMS (3.214±0.568, 1.821±0.863, t=7.151, P<0.05), CSMRS(5.286±0.680, 2.489±0.921, t=14.533, P<0.05) and there was statistical difference (P<0.05). No significant adverse reactions occured during medication in the SLIT group. A total of 12 cases were shed in the SLIT group, so the compliance rate was 70%. The four reasons were that patients considered the course was long (4 cases, 33%); the drugs were expensive (3 cases, 25%); patients were busy with their work and life (3 cases, 25%); patients were affected by the outbreak (2 cases, 17%). In summary, Artemisia pollen sublingual drops may improve the symptoms of the patients who got allergic rhinitis caused by Artemisia pollen after the treatment for one year. However, due to the lack of sufficient understanding of immunotherapy or the difficulty in adhering to standardized medication, the compliance with sublingual immunotherapy is still poor, the compliance with sublingual immunotherapy needs to be further improved through patient education.

Objective: To analyze the level and influence factors of inflammatory factors among electrical workers in Hainan Province. Methods: A total of 509 electrical workers were selected as the research subjects with random cluster sampling in September 2020. Basic information was collected by questionnaire, the serum IL-6, IL-8 and TNF-α levels of the subjects were detected by Luminex.Mann-Whitney U test and Kruskal-wallis H test were used for univariate analysis. Ordinal logistic regression analysis was used for potential influencing factors of the level of inflammatory factors. Results: The median concentrations of IL-6, IL-8 and TNF-α in serum were 2.78, 9.77 and 8.18 pg/ml. Compared with women, male was a risk factor for the increase of IL-6 levels (OR=1.80, 95%CI: 1.08~3.00, P=0.024) . Compared with 51-60 years old, 21-31 years old (OR=0.27, 95%CI: 0.18~0.42, P<0.001) , 31-41 years old (OR=0.27, 95%CI: 0.17~0.43, P<0.001) and 41-51 years old (OR=0.64, 95%CI: 0.41~0.99, P=0.043) were protective factors for the increase of IL-8 level. Compared with day shift workers, shift work was a risk factor for the increase of IL-8 level (OR=1.73, 95%CI: 1.21~2.48, P=0.003) . Compared with women, male was a risk factor for the increase of TNF-α levels (OR=2.87, 95%CI: 1.70~4.86, P<0.001) . Compared with workers who exposed to 7 or more occupational hazard factors, exposed to 1~3 (OR=0.53, 95%CI: 0.30~0.92, P=0.024) occupational hazard factors were protective factors for the increase of TNF-α levels. Conclusion: The level of inflammatory factors was related to sex, age, work system and occupational environment, which can provide basic data for follow-up research on occupational population.

Objective:To investigate the radiosensitization effect of low-dose sulfasalazine (SAS) on colorectal cancer (CRC) cells.Methods:Proliferation inhibition effect of SAS on CRC cells was detected by CCK-8 assay, and the concentration of SAS in vitro assays was based on its IC10 value. CRC cells were treated with SAS alone or combined with inhibitors of apoptosis, autophagy, ferroptosis and necroptosis, then cell viability was detected by CCK-8 assay. Trypan blue staining, clone formation assay and cell growth curves were used to verify the radiosensitization effect of SAS on CRC cells in vitro. CRC cells were treated with SAS and radiotherapy, then the intracellular contents of lipid peroxidation and the protein levels of GPX4, PTGS2, cleaved PARP and active caspase 3 were evaluated, respectively. Subcutaneous xenograft tumor mouse model was established to further verify the radiosensitization effect of SAS in vivo. Results:High dose (lethal dose) of SAS could induce apoptosis and ferroptosis in CRC cells. Low dose (non-lethal dose) of SAS enhanced the radiosensitivity of CRC cells in vitro, and the radiosensitivity effect of SAS could only be abolished by ferroptosis inhibitor (Fer-1). Low dose of SAS combined with radiotherapy significantly down-regulated the expression of GPX4, whereas increased the intracellular lipid peroxidation levels and the expression of PTGS2. SAS also showed significant radiosensitization effect in subcutaneous xenograft tumor model. Conclusion:Our findings suggest that low-dose SAS could increase the radiosensitivity of CRC cells by promoting ferroptosis.

ObjectiveTo determine the value of MRI blooming sign in differentiating benign and malignant small breast masses and investigate its radiologic-pathologic correlation. MethodsThis retrospective study included 554 small breast masses （291 malignant and 263 benign） which were ≤ 2 cm and validated by pathology analysis between June 2016 and September 2020. All 554 patients underwent breast MRI. The clinical characteristics and MR features were analyzed. Univariate and multivariate regression analysis were performed to identify the independent risk factors of breast cancer. Two diagnostic models were constructed based on independent risk factors （model 1 included blooming sign and model 2 didn’t）. ROC curve was used to evaluate the diagnostic performances of the two models. The histological changes of peritumoral tissues in all small masses were analyzed. ResultsThe blooming sign was positive in 199 cases （68.4%） of the malignant masses and 25 cases （9.5%） of the benign ones （P＜0.05）. Univariate and multivariate regression analysis showed that age， lesion diameter， margin， ADC value， time signal intensity curve type and blooming sign were independent risk factors for breast cancer. Odds ratio were 1.065， 4.515， 2.811， 0.013， 3.487 and 13.894， respectively. Their corresponding 95%CI were （1.034， 1.097）， （2.368， 8.608）， （1.954， 4.045）， （0.004， 0.049）， （2.087， 5.826） and （7.026， 27.477）， respectively. The diagnostic performance of model 1 （blooming sign included） was better than that of model 2 （blooming sign not included； AUC： 0.938 vs 0.897， P < 0.05）. Histopathological analysis showed that the blooming sign was related to peritumoral lymphocyte infiltration and vascular proliferation. ConclusionsMRI blooming sign is helpful for distinguishing breast cancer from benign masses. The correlated histopathological basis may be peritumoral lymphocyte infiltration and neovascularization.

Leaves of Euryale ferox are rich in anthocyanins. Anthocyanin synthesis is one of the important branches of the flavonoid synthesis pathway, in which flavonoid 3'-hydroxylase(F3'H) can participate in the formation of important intermediate products of anthocyanin synthesis. According to the data of E. ferox transcriptome, F3'H cDNA sequence was cloned in the leaves of E. ferox and named as EfF3'H. The correlation between EfF3'H gene expression and synthesis of flavonoids was analyzed by a series of bioinforma-tics tools and qRT-PCR. Moreover, the biological function of EfF3'H was verified by the heterologous expression in yeast. Our results showed that EfF3'H comprised a 1 566 bp open reading frame which encoded a hydrophilic transmembrane protein composed of 521 amino acid residues. It was predicted to be located in the plasma membrane. Combined with predictive analysis of conserved domains, this protein belongs to the cytochrome P450(CYP450) superfamily. The qRT-PCR results revealed that the expression level of EfF3'H was significantly different among different cultivars and was highly correlated with the content of related flavonoids in the leaves. Eukaryotic expression studies showed that EfF3'H protein had the biological activity of converting kaempferol to quercetin. In this study, EfF3'H cDNA was cloned from the leaves of E. ferox for the first time, and the biological function of the protein was verified. It provi-ded a scientific basis for further utilizing the leaves of E. ferox and laid a foundation for the further analysis of the biosynthesis pathway of flavonoids in medicinal plants.

BACKGROUND: Imprecise interpretation of coronary angiograms was reported and resulted in inappropriate revascularization. Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score is a comprehensive system to evaluate the complexity of the overall lesions. We hypothesized that a real-time SYNTAX score feedback from image analysts may rectify the mis-estimation and improve revascularization appropriateness in patients with stable coronary artery disease (CAD). METHODS: In this single-center, historical control study, patients with stable CAD with coronary lesion stenosis ≥50% were consecutively recruited. During the control period, SYNTAX scores were calculated by treating cardiologists. During the intervention period, SYNTAX scores were calculated by image analysts immediately after coronary angiography and were provided to cardiologists in real-time to aid decision-making. The primary outcome was revascularization deemed inappropriate by Chinese appropriate use criteria for coronary revascularization. RESULTS: A total of 3245 patients were enrolled and assigned to the control group (08/2016-03/2017, n = 1525) or the intervention group (03/2017-09/2017, n = 1720). For SYNTAX score tertiles, 17.9% patients were overestimated and 4.3% were underestimated by cardiologists in the control group. After adjustment, inappropriate revascularization significantly decreased in the intervention group compared with the control group (adjusted odds ratio [OR]: 0.83; 95% confidence interval [CI]: 0.73-0.95; P = 0.007). Both inappropriate percutaneous coronary intervention (adjusted OR: 0.82; 95% CI: 0.74-0.92; P < 0.001) and percutaneous coronary intervention utilization (adjusted OR: 0.88; 95% CI: 0.79-0.98; P = 0.016) decreased significantly in the intervention group. There was no significant difference in 1-year adverse cardiac events between the control group and the intervention group. CONCLUSIONS: Real-time SYNTAX score feedback significantly reduced inappropriate coronary revascularization in stable patients with CAD. CLINICAL TRIAL REGISTRATION Nos.
