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 identify the risk factors in mortality of pediatric acute respiratory distress syndrome (PARDS) in pediatric intensive care unit (PICU). Methods: Second analysis of the data collected in the "efficacy of pulmonary surfactant (PS) in the treatment of children with moderate to severe PARDS" program. Retrospective case summary of the risk factors of mortality of children with moderate to severe PARDS who admitted in 14 participating tertiary PICU between December 2016 to December 2021. Differences in general condition, underlying diseases, oxygenation index, and mechanical ventilation were compared after the group was divided by survival at PICU discharge. When comparing between groups, the Mann-Whitney U test was used for measurement data, and the chi-square test was used for counting data. Receiver Operating Characteristic (ROC) curves were used to assess the accuracy of oxygen index (OI) in predicting mortality. Multivariate Logistic regression analysis was used to identify the risk factors for mortality. Results: Among 101 children with moderate to severe PARDS, 63 (62.4%) were males, 38 (37.6%) were females, aged (12±8) months. There were 23 cases in the non-survival group and 78 cases in the survival group. The combined rates of underlying diseases (52.2% (12/23) vs. 29.5% (23/78), χ²=4.04, P=0.045) and immune deficiency (30.4% (7/23) vs. 11.5% (9/78), χ²=4.76, P=0.029) in non-survival patients were significantly higher than those in survival patients, while the use of pulmonary surfactant (PS) was significantly lower (8.7% (2/23) vs. 41.0% (32/78), χ²=8.31, P=0.004). No significant differences existed in age, sex, pediatric critical illness score, etiology of PARDS, mechanical ventilation mode and fluid balance within 72 h (all P>0.05). OI on the first day (11.9(8.3, 17.1) vs.15.5(11.7, 23.0)), the second day (10.1(7.6, 16.6) vs.14.8(9.3, 26.2)) and the third day (9.2(6.6, 16.6) vs. 16.7(11.2, 31.4)) after PARDS identified were all higher in non-survival group compared to survival group (Z=-2.70, -2.52, -3.79 respectively, all P<0.05), and the improvement of OI in non-survival group was worse (0.03(-0.32, 0.31) vs. 0.32(-0.02, 0.56), Z=-2.49, P=0.013). ROC curve analysis showed that the OI on the thind day was more appropriate in predicting in-hospital mortality (area under the curve= 0.76, standard error 0.05,95%CI 0.65-0.87,P<0.001). When OI was set at 11.1, the sensitivity was 78.3% (95%CI 58.1%-90.3%), and the specificity was 60.3% (95%CI 49.2%-70.4%). Multivariate Logistic regression analysis showed that after adjusting for age, sex, pediatric critical illness score and fluid load within 72 h, no use of PS (OR=11.26, 95%CI 2.19-57.95, P=0.004), OI value on the third day (OR=7.93, 95%CI 1.51-41.69, P=0.014), and companied with immunodeficiency (OR=4.72, 95%CI 1.17-19.02, P=0.029) were independent risk factors for mortality in children with PARDS. Conclusions: The mortality of patients with moderate to severe PARDS is high, and immunodeficiency, no use of PS and OI on the third day after PARDS identified are the independent risk factors related to mortality. The OI on the third day after PARDS identified could be used to predict mortality.

BACKGROUND: Shenyankangfu Tablet (SYKFT) is a Chinese patent medicine that has been used widely to decrease proteinuria and the progression of chronic kidney disease. OBJECTIVE: This trial compared the efficacy and safety of SYKFT, for the control of proteinuria in primary glomerulonephritis patients, against the standard drug, losartan potassium. DESIGN, SETTING, PARTICIPANTS AND INTERVENTION: This was a multicenter, double-blind, randomized, controlled clinical trial. Primary glomerulonephritis patients, aged 18-70 years, with blood pressure ≤ 140/90 mmHg, estimated glomerular filtration rate (eGFR) ≥ 45 mL/min per 1.73 m MAIN OUTCOME MEASURES: The primary outcome was change in the 24-hour proteinuria level, after 48 weeks of treatment. RESULTS: A total of 735 participants were enrolled. The percent decline of urine protein quantification in the SYKFT group after 48 weeks was 8.78% ± 2.56% (P = 0.006) more than that in the losartan 50 mg group, which was 0.51% ± 2.54% (P = 1.000) less than that in the losartan 100 mg group. Compared with the losartan potassium 50 mg group, the SYKFT plus losartan potassium 50 mg group had a 13.39% ± 2.49% (P < 0.001) greater reduction in urine protein level. Compared with the losartan potassium 100 mg group, the SYKFT plus losartan potassium 100 mg group had a 9.77% ± 2.52% (P = 0.001) greater reduction in urine protein. With a superiority threshold of 15%, neither was statistically significant. eGFR, serum creatinine and serum albumin from the baseline did not change statistically significant. The average change in TCM syndrome score between the patients who took SYKFT (-3.00 [-6.00, -2.00]) and who did not take SYKFT (-2.00 [-5.00, 0]) was statistically significant (P = 0.003). No obvious adverse reactions were observed in any group. CONCLUSION: SYKFT decreased the proteinuria and improved the TCM syndrome scores of primary glomerulonephritis patients, with no change in the rate of decrease in the eGFR. SYKFT plus losartan potassium therapy decreased proteinuria more than losartan potassium therapy alone. TRIAL REGISTRATION NUMBER NCT02063100 on ClinicalTrials.gov.

Aim To explore the main pathways and possible mechanisms of saffron in treatment of depression using network pharmacology. Methods A network of active components of saffron-depression disease target was constructed through the TCM System Pharmacology Database (TCMSP), Genecards, Uniprot database, Cytoscape software, and ClueGo analysis tool, and GO biological process and KEGG pathway enrichment analysis were performed, and molecular docking verification was carried out using Autodock vina software. Results The five main chemical components quercetin, kaempferol, crocealdehyde, crocetin, and isorhamnetin may pass through the IL-17 signaling pathway, HIF-1 signaling pathway and Toll-like inflammatory pathways such as receptor signaling pathway, PI3K-Akt signaling pathway, MAPK signaling pathway, relaxin signaling pathway, Thl7 cell differentiation and other pathways, playing an antidepressant effect. In the PI3K-Akt signaling pathway and MAPK signaling pathway, the targets of saffron for depression were mainly enriched in multiple targets such as BD-NF, TNF, IL-1, IL-6, MAPK8, JUN, GSK3B, N0S3 and so on. The results of molecular docking verification indicated a good docking effect of saffron and crocetin with the BDNF target in the antidepressant pathway of saffron. Conclusions The mechanism of saffron treatment of depression is mainly reflected in the regulation of neurotrophic factors, anti-inflammatory, anti-oxida-tive stress, etc., providing a theoretical basis for clinical application.

Abstract; Aim To explore the effect of icariin (ISO) in mice. Methods C57BL/6 mice were ran- (ICA) on myocardial fibrosis induced by isoproterenol domly divided into control group, ISO group, low-dose (15 mg • kg"1), middle-dose (30 mg • kg"1) and high-dose (60 mg • kg"1) of ICA-treated group and Losartan-treated group ( 9 mg • kg"1 ). The control group was subcutaneously injected with normal saline, and the other groups were subcutaneously injected with ISO (5 mg • kg"1, qd) continuously 14 days to established the myocardial fibrosis model. The ICA-treated groups and Losartan-treated group were simultaneously intragastrically administered of ICA or Losartan, respectively. And the other groups received the same a- mount of double distilled water. The left ventricular e- jection fraction (LVEF) and the left ventricular fraction shortening rate ( LVFS) were evaluated by the small animal ultrasound. The heart mass index (HMI) was calculated. The left ventricular collagen deposition was detected by Masson staining. The protein expressions of a-SMA, MMP-2, MMP-9 and TIMP-1 in the left ventricular tissue were detected by Western blot. Results ICA (30, 60 mg • kg"1) and Losartan could inhibit the decreased LVEF and LVFS, the increased HMI and left ventricular collagen deposition, the up- regulated a-SMA and MMP-9 protein expression, the down-regulated MMP-2 and TIMP-1 protein expression in the left ventricular tissues induced by ISO. Conclusions ICA can improve myocardial fibrosis induced by ISO in mice, and the underlying mechanism may be related to the regulation of the protein expression of a- SMA and MMPs/TIMP-1.

Aim To investigate the role of eNOS/PKG- 1 pathway in L-arginine (L-arg) intervention in right ventricular remodeling induced by monocrotaline (MCT) in Sprague Dawley (SD) rats with the aid of the tool medicine L-NAME. Methods Twenty SD rats were randomly divided into control group, MCT group, L-Arg group and L-Arg + L-NAME group. The general condition of rats was observed; the right ventricular pressure of rats was measured by right heart catheterization; the rats and the right ventricle were weighed and the right ventricular mass index was calculated; the morphological changes of the right ventricular were observed by H&E staining; the protein expressions of cTnl, eNOS and PKG-1 were detected by Western blot in the right ventricular. Results Compared with control group, right ventricular max pressure and right ventricular mass index significantly increased ( P < 05) ; the weight of rats in MCT group was significantly reduced ( P < 0. 05); the right ventricular myocytes were hypertrophic, disordered and infiltrated with inflammatory cells; the protein expression of cTnl was obviously up-regulated ( P < 0. 05 ) ; the protein expressions of eNOS and PKG-1 were significantly down- regulated ( P < 0. 05 ) . L-arg could significantly improve the above changes ( P < 0. 05 ). However, the effects of L-arg were inhibited by eNOS inhibitor L- NAME. Conclusions L-arg can improve the right ventricular remodeling in rats induced by MCT, and the mechanism may be related to the up-regulation of the protein levels of eNOS and PKG-1.

Since the outbreak of 2019-nCoV, the epidemic has developed rapidly and the situation is grim. LANCET figured out that the 2019-nCoV is closely related to "cytokine storm". "Cytokine storm" is an excessive immune response of the body to external stimuli such as viruses and bacteria. As the virus attacking the body, it stimulates the secretion of a large number of inflammatory factors: interleukin(IL), interferon(IFN), C-X-C motif chemokine(CXCL) and so on, which lead to cytokine cascade reaction. With the exudation of inflammatory factors, cytokines increase abnormally in tissues and organs, interfering with the immune system, causing excessive immune response of the body, resulting in diffuse damage of lung cells, pulmonary fibrosis, and multiple organ damage, even death. Arachidonic acid(AA) metabolic pathway is principally used to synthesize inflammatory cytokines, such as monocyte chemotactic protein 1(MCP-1), tumor necrosis factor(TNF), IL, IFN, etc., which is closely related to the occurrence, development and regression of inflammation. Therefore, the inhibition of AA metabolism pathway is benefit for inhibiting the release of inflammatory factors in the body and alleviating the "cytokine storm". Based on the pharmacophore models of the targets on AA metabolic pathway, the traditional Chinese medicine database 2009(TCMD 2009) was screened. The potential herbs were ranked by the number of hit molecules, which were scored by pharmacophore fit value. In the end, we obtained the potential active prescriptions on "cytokine storm" according to the potential herbs in the "National novel coronavirus pneumonia diagnosis and treatment plan(trial version sixth)". The results showed that the hit components with the inhibitory effect on AA were magnolignan Ⅰ, lonicerin and physcion-8-O-β-D-glucopy-ranoside, which mostly extracted from Magnoliae Officinalis Cortex, Zingiberis Rhizoma Recens, Lonicerae Japonicae Flos, Rhei Radix et Rhizoma, Salviae Miltiorrhizae Radix et Rhizoma, Scutellariae Radix, Gardeniae Fructus, Ginseng Radix et Rhizoma, Arctii Fructus, Dryopteridis Crassirhizomatis Rhizoma, Paeoniaeradix Rubra, Dioscoreae Rhizoma. Finally the anti-2019-nCoV prescriptions were analyzed to obtain the potential active prescriptions on AA metabolic pathway, Huoxiang Zhengqi Capsules, Jinhua Qinggan Granules, Lianhua Qingwen Capsules, Qingfei Paidu Decoction, Xuebijing Injection, Reduning Injection and Tanreqing Injection were found that may prevent 2019-nCoV via regulate cytokines. This study intends to provide reference for clinical use of traditional Chinese medicine to resist new coronavirus.

Objective To learn the epidemiological characteristics of HIV/AIDS cases aged 15-24 years in Shaoxing for making targeted prevention and control measures among young people. Methods To analyze the HIV/AIDS cases' distribution, route of transmission and reported route according to the cases which were reported 2003-2016 and aged 15-24 years. Results There were 325 cases had been reported. The epidemic had spread outward to each county, and transient population was accounted for 64.00%, and the ratio of male to female was 2.46:1. Career was widely dispersed, and farmers/migrant workers accounted for 31.08% , and students accounted for 10.15% . Homosexual transmission accounted for 41.29% , and heterosexual transmission accounted for 51.08% . The cases that were locality census register/high school education or above/unmarried adolescent, and professional for business services and student's homosexual transmission ratio was higher than that of heterosexual transmission. Voluntary counseling and testing was the major detection route which accounted for 16.9%. Conclusion The results showed that the male who aged 15-24 years was the most susceptible population. It is necessary to carry out effective measures to prevent and control HIV/AIDS transmission among young people, especially MSM and out-of-school youth.

The five-flavor theory of traditional Chinese medicines (TCM) and the flavor efficacy generation mechanism has long been focuses and difficulties in studies on traditional Chinese medicinal properties. In this paper, by using the pharmacophore-based virtual screening technique, the authors discussed the relations between the pungent property and transient receptor potential vanilloid 1 (TRPV1) by studying the TCM components' role in regulating TRPV1 ion channel. The results showed that the matching relationship between TRPV1 agonist pharmacophore model and TCM chemical components could identify the active ingredients from pungent herbs. Therefore, the authors proposed that TRPV1 is one of the potential targets for efficient pungent herbs. The pungent property of TCMs is decided by its chemical components, and consistent with the inherited and additive characteristics.
