There were three new blood group systems including the KANNO blood group system, the Sid blood group system and the CTL2 blood group system (provisional status), have been registered by the International Society of Blood Transfusion (ISBT) registered Science August 2019. The main reason for this update is that the significant SNPs of the KANNO blood group system (rs1800014) and the Sid blood group system (rs7224888) have been found through genome-wide association studies and whole exome sequencing. The new genetic evidences are consistent with the current immunological findings. In addition, although CTL2 antigen has been found on erythrocyte ghost (erythrocyte membrane) since 2017, CTL2 blood group system is still in provisional status due to lack of serological and genetic evidence. In this review, the experimental research advances of these three ISBT blood group systems and discuss the clinical value of the relevant researches was summarized briefly.
To investigate the clinical value of expression level of interleukin-2 receptor (IL-2R) and interleukin-8 (IL-8) in the fever patients with hematological malignancies.
A total of 121 inpatients in the First Affiliated Hospital of Anhui Medical University from April 2018 to October 2019 were enrolled in this study. The patients were separated into infection group (61 cases) and non-infection group (60 cases). In the meantime, 40 healthy people without fever or infection in the hospital for physical examination were set as matched group. C-reactive protein (CRP), procalcitonin (PCT), and cytokines were detected in all the patients with fever after admission and infection control. While, blood samples were taken from healthy people during physical examination.
The expression levels of IL-2R in infection group were higher than those in the control group (P<0.001), and the level of serum IL-2R in infection group was also higher than that in the non-infection group (P<0.05). Based on Spearman analysis, iagnosis and rational use of antibioties for clinician.
CRP, PCT, IL-2R, and IL-8 are useful parameters for diagnosis of the infectious fever in patients with hematological malignancies, which provides the basis of initial diagnosis and rational use of antibioties for clinician.
To analyze the distribution and drug resistance of pathogens sampled from the patients with bloodstream infection in the department of hematology of PLA General Hospital, so as to provide evidences for clinical prevention and control infection.
From January 2014 to December 2017, A total of 286 cases-time positive blood culture samples from 212 patients in the department of hematology of the General Hospital of Chinese PLA were collected. The clinical characteristics of patients and the distribution and drug resistance of pathogens were analyzed retrospectively.
182(63.64%) bacterial strains were Gram-negative, and the other 104(36.36%) were Gram-positive. There were 88 strains of Escherichia coli(30.77%), 34 strains of Pseudomonas aeruginosa(11.89%), 26 strains of Klebsiella pneumoniae(9.09%), 25 strains of Staphylococcus epidermidis(8.74%), 20 strains of Gram-positive rods(6.99%), 16 strains of Staphylococcus hominis(5.59%), 11 strains of Etaphylococcus haemolyticus(3.85%), 10 strains of Staphylococcus aureus(3.50%), 6 strains of Staphylococcus capitis(2.10%), 5 strains of Acinetobacter baumannii(1.75%) and so on. Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumoniae as Gram-negative bacteria were sensitive to amikacin. Acetylcholine Chloride mouse Staphylococcus epidermidis and Staphylococcus aureus as Gram-positive bacteria were sensitive to vancomycin and nitrofurantoin.
The blood culture patients with bloodstream infection in department of hematology of our hospital confirmed that more infections are Gram-negative. link2 The clinicians should choose suitable antibiotics according to the results of bacterial culture and drug sensitive test.

To analyze the characteristics, prognosis and risk factors of bloodstream infection in patients with hematological malignancies in the tropics, so as to provide evidence for the prevention and treatment of bloodstream infection.
The clinical features, blood culture results and prognosis of patients with bloodstream infection in patients with hematological malignancies admitted to Hainan Hospital of PLA General Hospital were retrospectively studied.
The most common primary infection site of the 81 patients with hematological malignancies was lung (46.91%), followed by PICC (11.11%). The detection rate of Gram-positive bacteria and Gram-negative bacteria in the blood culture was 60.98% and 30.02%, respectively. Coagulase-negative staphylococci was the most common Gram-positive bacteria resulting in bloodstream infection in our study. link3 Of the Gram-negatives, Klebsiella pneumoniae (34.38%) was predominant, followed by Escherichia coli (18.75%) and Pseudomonas aeruginosa (18.75%). Gram-positive bacteria was h the tropics. A correct treatment relieving disease and effective prevention and treatment of septic shock can reduce mortality of patients with bloodstream infection in patients with hematological malignancies in the tropics.
Gram-positive bacteria are the main pathogens causing bloodstream infections in patients with hematological malignancies in the tropics. Improving the care of PICC is an important measure to reduce the incidence of bloodstream infection in patients with hematological malignancies in the tropics. A correct treatment relieving disease and effective prevention and treatment of septic shock can reduce mortality of patients with bloodstream infection in patients with hematological malignancies in the tropics.
To investigate the difference in the therapeutic effect of plasma exchange and continuous renal replacement therapy (PE+CRRT) combined with chemotherapy in the treatment of children with severe Epstein-Barr virus-associated hemophagocytic lymphohistiocytosis (EBV-HLH) and non-EBV-HLH.
The clinical data of 21 cases of all children with severe HLH treated by PE+CRRT combined with chemotherapy from January 2017 to January 2020 were collected and retrospectively analyzed. According to the presence of EBV infection, the children were divided into EBV
group and EBV
group. The differences of the observation indexes between the children in the two groups and the improvement of the observation indexes of each group before and after treatment were compared.
Among the 21 children, 14 were divided into the EBV
group and 7 were divided into the EBV
group. There was no difference in age, sex and the number of organ damage between the children in the two groups (P>0.05). Duration of PE+CRRT was longer in thbefore treatment, EBV-DNA in the EBV
group were decreased significantly in 2-4 weeks after treatment (P<0.05). After PE+CRRT combined with chemotherapy, the overall survival rate of the children with severe HLH was 66.7%, and there was no significant difference in overall survival rate between EBV
group and EBV
group (P>0.05).
PE+CRRT combined with chemotherapy can reduce serum ferritin quickly, then improve organ function, and increase the overall survival rate of severe HLH, and it is a good effect on children with severe EBV-HLH and non-EBV-HLH.

To present one patient initially diagnosed with dermatomyositis(DM) who was eventually revealed to be diffuse large B-cell lymphoma(DLBCL) complicated with hemophagocytic syndrome(HPS), and to improve the understanding of the disease.
The clinical characteristics, diagnostic approach, treatment of the patient were retrospectively analyzed, and some related literatures were reviewed.
A 52-year-old female patient suffered from muscle weakness, elevated serum creatine kinase activity, electromyography changes and characteristic skin rashes and diagnosed as DM. The patient was treated with glucocorticoid therapy and the muscle strength, skin rashes, and creatine kinas index turns into remission. Subsequently, subcutaneous nodules appeared during treatment, and the patient was confirmed as DLBCL based on pathological biopsy; And the patient was considered HPS because of presenting with repeated fever, splenomegaly, cytopenias, hypofibrinogenemia, hypertriglyceridemia, hyperferritinemia, high levels of sCD25, low NK-cell activity and hemophagocytosis in bone marrow. But the patient refused chemotherapy, and only treated with "DXM+VP-16" to control hemophagocytic syndrome, and unfortunately died due to the disease progression.
Cutaneous involvement in diffuse large B-cell lymphoma and hemophagocytic syndrome patients with first presentation of dermatomyositis is relatively rare. Malignacy screening should be performed as soon as possible after newly diagnosed DM, so that the patient can get early diagnosis and effective treatment to improve survival rate.

To study the impact of anticoagulant to the quality of umbilical cord blood (UCB).
6060 cord blood units (CBUs) were classified into five groups, such as 28 ml (10-29) ml, 28 ml (30-69) ml, 28 ml (70-109) ml, 28 ml (110-150) ml and 28 ml (>150) ml according to volume ratio of anticoagulant and CBVs. The count of pre-cryopreservation total nucleated cell (pre-TNC), the viability of nucleated cell (VNC), the amount of CFU-GM and the ratio changes of CD34
were evaluated and analyzed statistically.
It was found that pre-TNC increased with the growth of volume of CBUs (r=0.9937) under the certain volume of antico-agulant, and the TNC in the minimum UCB volume group was (2.57±0.89)×10
; the VNC grew up with the increasing count viability of volume (r=0.9897), and the average viability of the minimum volume group remained over 95%; the CFU-GM climbed up with the increasing of volume (r=0.9024), and the number of CFV-GM in minimum volume group reached to of 89/×10
; CD34
% grew up with the increase of volume of CBUs (r=0.9641), and the ratio was (0.30±0.19)% for the minimum volume group.
In certain volume of anticoagulant in collection-bag, pre-TNC, VNC, CFU-GM and CD34
% are all dropped with the decrease of CBUs volume , however, all above-mentioned indexes in the minimun random group still meet the requirement for clinical administration.
