The concept of'harmony'is the soul of traditional Chinese culture,which has a profound impact on the formation and development of traditional Chinese medicine(TCM).TCM is rooted in traditional Chinese culture,and the mode of thinking in TCM is in line with traditional Chinese culture.Based on the harmony culture,TCM has developed a unique view of health,disease and therapeutics.From the view of the harmony culture and by combining with years of clinical experience in treating dermatosis,Chinese medical master XUAN Guo-Wei has applied the concept of'harmony'in the TCM syndrome differentiation and treatment system in clinic,and has developed the academic thoughts of harmonizing therapy for removing toxins for the diagnosis and treatment of dermatosis.The thoughts of harmonizing therapy for removing toxins includes four aspects,namely harmonizing yin and yang,harmonizing healthy qi and pathogenic qi,harmonizing water and fire(i.e.,clod and hot),and harmonizing the administration of formula and drugs,aiming to remove toxins and expel pathogens and value the harmony.The thoughts of harmonizing therapy for removing toxins will beneficial to the comprehensive understanding of the unique health-disease-therapeutics concept in TCM,and will be helpful for managing the doctor-patient relationship,which is of enlightening significance to the modern clinical practice with TCM.

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 investigate the effects of composite Sophora colon-soluble Capsule (CSCC) on gut microbiota-mediated short-chain fatty acids (SCFAs) production and downstream group 3 innate lymphoid cells (ILC3s) of dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) mice model. METHODS: The main components of CSCC were analyzed by hybrid ultra-high-performance liquid chromatography ion mobility spectromety quadrupole time-of-flight mass spectrometry (UHPLC-IM-QTOF/MS). Twenty-four male BALB/c mice were randomly divided into 4 groups (n=6) by using a computer algorithm-generated random digital, including control, DSS model, mesalazine, and CSCC groups. A DSS-induced colitis mice model was established to determine the effects of CSCC by recording colonic weight, colonic length, index of colonic weight, and histological colonic score. The variations in ILC3s were assessed by immunofluorescence and flow cytometry. The results of gut microbiota and SCFAs were acquired by 16s rDNA and gas chromatography-mass spectrometry (GC-MS) analysis. The expression levels of NCR⁺ ILC3^-, CCR6⁺ Nkp46^- (Lti) ILC3^-, and ILCreg-specific markers were detected by enzyme-linked immunosorbent assay, and real-time quantitative polymerase chain reaction and Western blot, respectively. RESULTS: The main components of CSCC were matrine, ammothamnine, Sophora flavescens neoalcohol J, and Sophora oxytol U. After 7 days of treatment, CSCC significantly alleviated colitis by promoting the reproduction of intestinal probiotics manifested as upregulation of the abundance of Bacteroidetes species and specifically the Bacteroidales_S24-7 genus (P<0.05). Among the SCFAs, the content of butyric acid increased the most after CSCC treatment. Meanwhile, compared with the model group, Lti ILC3s and its biomarkers were significantly downregulated and NCR⁺ ILC3s were significantly elevated in the CSCC group (P<0.01). Further experiments revealed that ILC3s were differentiated from Lti ILC3s to NCR⁺ ILC3s, resulting in interleukin-22 production which regulates gut epithelial barrier function. CONCLUSION CSCC may exert a therapeutic effect on UC by improving the gut microbiota, promoting metabolite butyric acid production, and managing the ratio between NCR⁺ ILC3s and Lti ILC3s.

Objective: To investigate the efficiency and safety of domestic tyrosine kinase inhibitor (TKI) dasatinib (Yinishu) as second-line treatment for patients with chronic myeloid leukemia in chronic phase (CML-CP). Methods: A retrospective analysis of clinical data of CML-CP patients who received domestic dasatinib as second-line treatment in the CML collaborative group hospitals of Hubei province from March 2016 to July 2018 was performed. The optimal response rate, the cumulative complete cytogenetic response (CCyR), the cumulative major molecular responses (MMR), progression free survival (PFS), event free survival (EFS) and adverse effects (AEs) of the patients were assessed at 3, 6 and 12 months of treatment. Results: A total of 83 CML-CP patients were enrolled in this study. The median follow-up time was 23 months. The optimal response rates at 3, 6 and 12 months in 83 CML-CP patients treated with dasatinib were 77.5% (54/71), 72.6% (61/75) and 60.7% (51/69), respectively. By the end of follow-up, the cumulative CCyR and MMR rates were 65.5% (55/80) and 57.1% (48/73), respectively. The median time to achieving CCyR and MMR was 3 months. During follow-up time, the PFS rate was 94.0% (79/83) and the EFS rate was 77.4% (65/83). The most common non-hematological AEs of dasatinib were edema (32.5%), rash itching (18.1%) and fatigue (13.3%). The common hematological AEs of dasatinib were thrombocytopenia (31.3%), leukopenia (19.3%) and anemia (6.0%). Conclusion: Domestic dasatinib was effective and safe as the second-line treatment of CML-CP patients and it can be used as an option for CML-CP patients.

Objective To evaluate and study percutaneous nephrolithotomy (PCNL) related factors in the treatment of renal calculi caused postoperative fever and its prevention measures. Methods Making a retrospective analysis of the clinical records of 150 patients who underwent PCNL, including age, gender, diabetes history and previous ipsilateral renal surgery, stone type, stone size, whether the complication of upper ureteral stones, preoperative urinary tract infection, hydronephrosis and pyonephrosis, preoperative renal fistula, postoperative centering vein pressure, intraoperative perfusion and the operation time from January 2015 to June 2017. After the operation, the patients were divided into two groups: fever group and non-fever group, and analyzed the related factors of the fever. Results Among the 150 cases, fever occurred in 27 cases after PCNL, taking up 18%. Gender, history of diabetes, staghorn calculi or staghorn stone, stone size, with ureteral calculi, preoperative urine leukocyte count, renal abscess, preoperative renal fistula, postoperative central venous pressure, intraoperative perfusion and operation time between the two groups, the differences that were statistically significant (P < 0.05). Logistic that multivariate analysis showed that female patients with upper ureteral calculi, perfusion, intraoperative volume,preoperative pyonephrosis, long operation time are independent risk factors of fever after operation (OR^>1, P<0.05). Conclusion Routine bacterial culture of urine should be performed before percutaneous nephrolithotomy, urinary tract infection and kidney empyema should be treated thoroughly. The reasonable shorter operative duration and perfusion fluid volume could significantly reduce the incidence of fever after PCNL.

BACKGROUNDA survey of early stage follicular lymphoma(FL) revealed that the rigorously staged FL patients at first diagnosis had a better outcome as compared with non-rigorous staged FL patients, but there were no similar reports in China.

OBJECTIVETo explore the relationship between the rigorous staging at first diagnosis and the prognosis of FL patients at different stages.

METHODSThe clinical data of 111 patients with newly diagnosed FL from 2008 to 2014 year were collected and analyzed. The rigorous staging included: (1) bone marrow aspiration and biopsy, (2) imaging examination of whole body including CT and ultrasounic scan, or PET/CT, either or both is defined as rigorous staging, or else as non-rigorous staging.

RESULTSThe FL patients at I-II stages by rigorous staging showed a superior progression-free survival(PFS) compared with non-rigorous staging patients(P=0.048). For all the patients, the age, serum LDH, bone marrow lesion and more than 3 foci of diameter larger than 3 cm correlated with prognosis in univariate analysis, and multivariate analysis revealed that the age, serum LDH and bone marrow imolvement were the independent prognostic factors.

CONCLUSIONRigorous staging leads to better outcomes, suggesting that accurate and appropriate testing is important for the patients at the first treatment. The close correlation of bone marrow with prognosis indicates that the evaluation of bone marrow is very important for the daily clinical practice.

Some unique subclasses of Camelidae antibodies are devoid of the light chain, and the antigen binding site is comprised exclusively of the variable domain of the heavy chain (VHH). The recombinant VHHs have a high potential as alternative reagents for the next generation of immunoassay. In particular, they might be very useful for molecular mimicry. The present study demonstrated an alpaca immunized with the F(ab')2 fragment of anti-aflatoxin B1 mAb and developed an important anti-idiotypic (anti-Id) responses. Antigen-specific elution method was used for panning private anti-Id VHHs from the constructed alpaca VHH library. The selected VHHs were expressed, renatured, purified, and then identified by a competitive enzyme-linked immunosorbent assay (ELISA). Our findings indicated that the VHH would be an alternative tool for haptens mimicry studies.

Lymphoblastic lymphoma (LBL) comprises 2% to 4% of non-Hodgkin lymphomas cases in adults, of which 85% to 90% of LBL in adults is of T-cell phenotype. This study was aimed to evaluate the clinical characteristics and prognostic factors of patients with mediastinal T-LBL. Based on the retrospective analysis of the clinical data of 35 patients with mediastinal T-LBL during the period from January 1998 to January 2011, the clinical characteristics and prognostic factors of mediastinal T-LBL were summarized. The results showed that the total of 35 patients were identified (male 24 and female 11), with a median age of 19 (5 - 52) years. The majority of patients were in stage III/IV, 16 cases (45.7%) presented bulky mediastinal mass. Intrathoracic effusions (pleural, pericardial) were not uncommon (62.9%). Overall survival rate (OS) and progression-free survival rate (PFS) at 3 years for the entire cohort were 36% and 24%, respectively. OS and PFS at 5 years were 25% and 16.7%, respectively. Anemia at diagnosis were an important, independent predictor of OS (P = 0.048). Bulky mass (P = 0.048), superior vena cava syndrome (P = 0.021), and abnormal PLT count at diagnosis was the independent prognostic factors for PFS (P = 0.021). It is concluded that the patients with primary mediastinal T-LBL are characterized by a low incidence, bad prognosis, and short survival. For patients accompanying with anemia, bulky mass and superior vena cava syndrome, their prognosis is worse.

OBJECTIVETo explore the role of SHP-1 promoter methylation on the pathogenesis and progression in myelodysplastic syndromes (MDS) and its related mechanism.

METHODS63 MDS patients were divided into low-grade (LG) group and high-grade (HG) group according to IPSS score system. Bone marrow samples were collected. Methylation specific-PCR (MSP) were used to detect the status of SHP-1 promoter methylation in bone marrow (BM) samples from different risk MDS patients and MDS cell line, SKK-1. Western blot was used to detect signal transduction and activator of transcription (STAT3) activation in SKK-1 cell line and MDS patients.

RESULTSNo SHP-1 promoter methylation could be detected in healthy controls BM. Partially methylation was found in SKK-1 cell line. Methylation rate of SHP-1 gene promoter was found in BM of 24.2% of low-grade MDS patients and 63.3% of high-grade MDS patients, the difference between these two groups was statistically significant (P < 0.05); Patients were divided into different groups according to WHO subtype, chromosomal karyotype and blast cells in bone marrow, methylation rates of SHP-1 were significantly higher in RAEB-II, poor karyotype group and samples with 0.11-0.19 blast cells (P < 0.05); The phosphorylation protein of STAT3 was detected in SKK-1 cell line. The expression of phosphorylation STAT3 was significantly higher in HG group than in LG group (66.7% vs 18.2%) (P < 0.05). There was a significant correlation between SHP-1 promoter methylation and STAT3 phosphorylation.

CONCLUSIONAbnormal methylation of SHP-1 gene promoter might have tentative role in the pathogenesis and progression of MDS, which may be involved in STAT3 activation. Detection of SHP-1 promoter methylation may be helpful to evaluate the prognosis of MDS.

The study was aimed to investigate the expression of stromal cell derived factor (SDF-1) in bone marrow (BM) and its relation with apoptosis of BM CD34(+) cell and angiogenesis in myelodysplastic syndrome (MDS). 40 patients with MDS were divided into low-risk group and high-risk group according to IPSS score system. BM samples were collected. SDF-1 levels, the apoptosis of CD34(+) cells and microvessel density (MVD) of BM were detected by ELISA, flow cytometry and immunochemistry, respectively. The results showed that the SDF-1 level in MDS patients was significantly higher than that in normal controls(p < 0.05), and SDF-1 level in low-risk group was significantly higher than that in high-risk group. Apoptosis of CD34(+) cells significantly increased in low-risk group compared with other groups (p < 0.05). MVD in BM biopsy significantly increased in high-risk MDS group (p < 0.05), compared with low-risk MDS group which also had higher MVD than the control group (p < 0.05). Positive correlation was found between apoptosis of CD34(+) cells and SDF-1 levels in low-risk group, and SDF-1 level and MVD in high-risk group. It is concluded that the expression of SDF-1, apoptosis of BM CD34(+) cells and MVD were significantly abnormal in MDS patients, especially in different risk group, suggesting that SDF-1 level is related to cell apoptosis and angiogenesis.
