Objective To analyze the diagnostic status of haemophilia in Chinese children in recent years,and to provide information for increasing the life quality of children with haemophilia in China.Methods The pediatric haemophilia cases registration data were collected and analyzed by using questionnaire,from January 1,2008 to March 30,2014 in 13 haemophilia treatment centers of haemophilia treatment center collaboration network of China pediatric group.These centers were from 12 provinces / municipalities.Results A total of 554 cases were collected;median age was 7.0 years old(0.1 to 17.9 years old);among them,481 cases(86.8％) were hemophilia A,and 73 cases were hemophilia B (13.2％);55 mild cases (9.9％),290 moderate cases (52.4％),and 209 severe cases (37.7％);162 cases(29.2％) had family history,the other 392 cases(70.8％) had no family history.The diagnosis was made at a median age of 12.0 month-old(0 to 180.0 months);the diagnosis time was 0.5 months(0 to 144.0 months) after the first bleeding;diagnosis timing with short interval was in 356 cases(64.3％),long interval was in 198 cases(35.7％).The diagnostic timing was not correlated with disease severity (P =0.812) or the family history (P =0.243);but correlated with the severity of first bleeding(P =0.027) and per capita gross domestic product (P ＜ 0.01) in patients' residence.From 1996 to 2013,the annual number of newly diagnosed cases was increasing year by year,with a higher proportion of short interval of diagnose timing.Conclusions With development of hemophilia work in China,the number of diagnosis of haemophilia children is increasing year by year.Moderate and severe hemorrhage are both taken seriously and diagnosed timely.But the diagnosis is delayed in some children.Chinese haemophilia work still need to be strengthen and the propaganda and diagnostic technology are to be popularized.

Objective:To investigate the expression profile of IL-36 family members in patients with coronary atherosclerotic heart disease (CAHD) and to assess the regulatory effects of exogenous IL-36 on CD8 + T cell function in CAHD patients. Methods:Twenty controls and 82 CAHD patients including 31 with stable angina pectoris (SAP), 27 with unstable angina pectoris (UAP) and 24 with acute myocardial infarction (AMI) were enrolled in this study. Anti-coagulant peripheral blood samples were collected. Plasma and peripheral blood mononuclear cells were isolated. The levels of IL-36α, IL-36β, IL-36γ and IL-36 receptor antagonist (IL-36RA) in plasma were measured by ELISA. CD8 + T cells were enriched. The expression of IL-36 receptor subunits at mRNA level was semi-quantified by real time PCR. Flow cytometry was used to detect the expression of programmed death-1 (PD-1), cytotoxic T lymphocytes associated protein-4(CTLA-4) and lymphocyte-activation gene-3 (LAG-3) in CD8 + T cells. Levels of periforin, granzyme B, granulysin, IFN-γ and TNF-α in the culture supernatants of CD8 + T cells were measured by ELISA. Purified CD8 + T cells from controls and AMI patients were stimulated with recombinant human IL-36RA. Changes in the expression of immune checkpoint molecules and the secretion of cytotoxic molecules and cytokines after IL-36RA stimulation were analyzed. One-way analysis of variance or paired t-test was used for statistical analysis. Results:There were no significant differences in plasma IL-36α, IL-36β or IL-36γ level between the control, SAP, UAP and AMI groups ( P>0.05). Plasma IL-36RA level was significantly down-regulated in the AMI group as compared with that in the control, SAP and UAP groups[(1 159.57±297.83) pg/ml vs (1 773.47±754.29) pg/ml, (1 600.12±740.48) pg/ml and (1 578.72±720.42) pg/ml; P<0.05]. The expression of IL-1 receptor 6 (IL-1R6) and IL-1 receptor accessory protein (IL-1RAcP) at mRNA level, the expression of PD-1 and CTLA-4, and the secretion of IFN-γ and TNF-α by CD8 + T cells showed no significant differences between the four groups ( P>0.05). Periforin, granzyme B and granulysin levels secreted by CD8 + T cells of the AMI group were significantly higherthan those of the control, SAP and UAP groups ( P<0.05). In the control group, recombinant human IL-36RA stimulation did not affect the expression of immune checkpoint molecule or the secretion of cytotoxic molecules and cytokines by CD8 + T cells ( P>0.05). In the AMI group, the percentage of PD-1 + CD8 + T cells increased after recombinant human IL-36RA stimulation ( P=0.033), but no significant change in the percentage of CTLA-4 + CD8 + T cells was observed ( P=0.288). Moreover, recombinant human IL-36RA stimulation suppressed the CD8 + T cells of AMI patients to secrete periforin, granzyme B and granulysin ( P<0.05), but not affect the secretion of IFN-γ and TNF-α ( P>0.05). Conclusions:The reduced IL-36RA level in AMI patients might induce the enhancement of CD8 + T cell activity by promoting CD8 + T cells to secrete cytotoxic molecules, which was involved in the immunopathogenesis of AMI.

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.
