OBJECTIVE: To analyze the clinical characteristics of hemophagocytic syndrome (HLH) children with different EB virus (EBV) DNA loads, and to explore the relationship between differential indicators and prognosis. METHODS: Clinical data of 73 children with HLH treated in our hospital from January 2015 to April 2022 were collected. According to EBV DNA loads, the children were divided into negative group (≤5×10² copies/ml), low load group (>5×10²-<5×10⁵ copies/ml) and high load group (≥5×10⁵copies/ml）. The clinical symptoms and laboratory indexes of the three groups were compared, and the ROC curve was used to determine the best cut-off value of the different indexes. Cox regression model was used to analyze the independent risk factors affecting the prognosis of children, and to analyze the survival of children in each group. RESULTS: The proportion of female children, the swelling rate of liver and spleen lymph nodes and the involvement rate of blood, liver, circulation and central nervous system in the high load group were higher than those in the negative group. The incidence of disseminated intravascular coagulation(DIC) and central nervous system(CNS) involvement in the high load group were higher than those in the low load group. The liver swelling rate and circulatory system involvement rate in the low load group were higher than those in the negative group(P<0.05). PLT counts in the high load group were significantly lower than those in the negative group, and the levels of GGT, TBIL, CK-MB, LDH, TG, SF, and organ involvement were significantly higher than those in the negative group. The levels of CK, LDH, SF and the number of organ involvement in the high load group were significantly higher than those in the low load group. The levels of GGT and TBIL in low load group were significantly higher than those in negative group. In terms of treatment, the proportion of blood purification therapy in the high and low load group was significantly higher than that in the negative group(P<0.01). ROC curve analysis showed that the best cut-off values of PLT, LDH, TG and SF were 49.5, 1139, 3.12 and 1812, respectively. The appellate laboratory indicators were dichotomized according to the cut-off value, and the differential clinical symptoms were included in the Cox regression model. Univariate analysis showed that LDH>1139 U/L, SF>1812 μg/L, dysfunction of central nervous system, number of organ damage, DIC and no blood purification therapy were the risk factors affecting the prognosis of children (P<0.05); Multivariate analysis shows that PLT≤49.5×10⁹/L and dysfunction of central nervous system were risk factors affecting the prognosis of children (P<0.05). Survival analysis showed that there was no significant difference in the survival rate among the three groups. CONCLUSION The incidence of adverse prognostic factors in children with HLH in the EBV-DNA high load group is higher, and there is no significant difference in the survival rate of the three groups after blood purification therapy. Therefore, early identification and application of blood purification therapy is of great significance for children with HLH in the high load group.

OBJECTIVE: To investigate the diagnostic efficacy of seven glomerular filtration rate (GFR) evaluation formulas Schwartz2009, Schwartz1976, Counahan-Barratt, Filler, CKD-EPI_scysc, Cockrofi-Gault, CKD-EPI_ScysC-Scr in high concentration of methotrexate (HDMTX) chemotherapy dose adjusted cut-off point (GFR ≤85 ml/min) in children with acute lymphoblastic leukemia (ALL). METHODS: One hundred and twenty-four children with ALL were included in the study. GFR determined by renal dynamic imaging (sGFR) was used as the standard to evaluate the accuracy, consistency of eGFR calculated by seven formulas and sGFR, and the diagnostic efficacy of each formula when the sGFR ≤85 ml/min boundary. RESULTS: All of the accuracy of eGFR estimated by Schwartz2009 were greater than 70% in the 0-3, >4 and ≤6, >6 and ≤9, >9 and ≤16 years old group and male group, and the consistency exceeded the professional threshold. When the sensitivity of the ROC curve sGFR ≤85 ml/min was 100% of CKD-EPI_scysc in the 0-3, >3 and ≤4 years old group, Filler in the >3 and ≤4 years old group, and Cockrofi-Gault in the >6 and ≤9 years old group, the specificity was 73.02%, 78.95%, 78.95%, 69.32%, respectively, and the AUC under the ROC curve was the largest (P<0.05). CONCLUSION Schwartz2009 formula predicts the highest accuracy of eGFR in the 7 glomerular filtration rate. CKD-EPI_scysc, Filler, and Cockrofi-Gault formulas have more guiding signi-ficance for the adjustment of HDMTX chemotherapy in pre-adolescence in children with ALL when sGFR ≤85 ml/min.

OBJECTIVE: To compare the clinical efficacy between governor vessel moxibustion combined with warming acupuncture based on the supporting-yang theory and simple warming acupuncture for knee osteoarthritis (KOA) with yang deficiency and cold congelation. METHODS: A total of 64 patients with KOA of yang deficiency and cold congelation were randomized into a combination group (32 cases, 2 cases dropped off) and a warming acupuncture group (32 cases, 1 case dropped off). In the warming acupuncture group, warming acupuncture was applied at Zusanli (ST 36), Guanyuan (CV 4) and Dubi (ST 35), Neixiyan (EX-LE 4), etc. on the affected side, once a day. On the basis of the treatment in the warming acupuncture group, governor vessel moxibustion was applied in the combination group, once a week. The 14-day treatment was taken as one course, and totally 2 courses with 2-day interval were required in the two groups. The clinical symptom score, the visual analogue scale (VAS) score and the Western Ontario and McMaster Universities arthritis index (WOMAC) score were observed before treatment, after treatment and in the follow-up of 12 weeks after treatment; the volume of suprapatellar bursa effusion was detected before and after treatment; the clinical efficacy was evaluated after treatment and in the follow-up in the two groups. RESULTS: After treatment and in the follow-up, the scores of clinical symptom, VAS and WOMAC were decreased compared before treatment in both groups (P<0.05), and those in the combination group were lower than the warming acupuncture group (P<0.05). After treatment, the volume of suprapatellar bursa effusion was decreased compared before treatment in both groups (P<0.05). After treatment and in the follow-up, the total effective rates were 93.3% (28/30) and 86.7% (26/30) in the combination group, which were superior to 87.1% (27/31) and 74.2% (23/31) in the warming acupuncture group respectively (P<0.05). CONCLUSION Governor vessel moxibustion combined with warming acupuncture can improve the clinical symptoms i.e. pain and dysfunction and reduce the volume of suprapatellar bursa effusion in KOA patients with yang deficiency and cold congelation, its short-term effect and long-term effect are both superior to simple warming acupuncture.

OBJECTIVE: To distinguish clinical features, safety and efficiency of endoscopic retrograde cholangiopancreatography (ERCP) in patients after bilioenteric anstomosis based on retrospectively analyzed clinical data and endoscopy procedures. METHODS: Data extracted from patients after bilioenteric anstomosis due to biliary disease treated with ERCP from January 2005 to December 2021 in the Department of Gastroenterology, Peking University Third Hospital were retrospectively analyzed. Clinical data and endoscopic pictures were reevaluated and analyzed. The patients were divided into three groups, including the patients with choledochoduodenostomy (CDD), Roux-en-Y hepaticojejunostomy (RYHJ) and Whipple. Differences between ERCP success and failure were conducted. RESULTS: In the study, 89 cases with 132 ERCP procedures were involved, 9-80 years old, median 57 years old, containing 4 CDD, 30 RYHJ, 54 Whipple and 1 bile duct ileocecal anastomosis patients; The time between ERCP and surgery were 30 (1-40), 2.75 (0.5-14), 2 (0.3-19), and 10 years, respectively; The time between surgery and symptom were 240 (3-360), 12 (1-156), 22 (0-216), and 60 months, respectively. Fifty percent of CDD could succeed only under local anaesthesia, RYHJ (96.7%) and Whipple (100.0%) needed under general anaesthesia (P < 0.001). Successful first entry rates of CDD, RYHJ and Whipple were 100.0%, 40.0% and 77.8%, respectively. After changing the endoscopy type, successful entry rate could increase to 43.3% of RYHJ and 83.3% of Whipple. The successful entry rate of different anastomotic methods was significant (P < 0.001). The cannulation success rates of CDD, RYHJ and Whipple were 100.0%, 53.8% and 86.7% respectively, with significant difference between the groups (P=0.031). ERCP success rates of CDD, RYHJ and Whipple were 100.0%, 33.3% and 78.8% respectively, with significant difference between the groups (P < 0.001). Complications were found in 23.9% (21/88) patients, including infection (14.8%), pancreatitis (9.2%), bleeding (3.4%), and perforation (2.3%) ranked by incidence. Causes of ERCP in post bilioenteric anstomosis were anastomotic stenosis (50.0%, benign 39.3%, malignant 10.7%), choledocholithiasis (37.5%) and reflux cholangitis (12.5%). Anastomotic method was the only predicting factor of ERCP success in patients after bilioenteric anstomosis (OR=7, 95%CI: 2.591-18.912, P < 0.001). CONCLUSION ERCP in post bilioenteric anstomosis patients with gastrointestinal reconstruction need general anaesthe-sia, with good safety and efficiency. The successful rate of RYHJ was significantly lower than Whipple. Anastomotic method was the only predicting factor of ERCP success.

OBJECTIVE: To analyze the clinical efficacy of haploidentical hematopoietic stem cell transplantation (haplo-HSCT) by using parental donors on thalassemia patients. METHODS: The 13 thalassemia patients treated by haplo-HSCT using parental donors in our hospital from July 1, 2016, to July 1, 2020 were retrospectively reviewed. Hematopoiesis reconstitution, the incidence of GVHD, infections and the long-term survival of the patients were analyzed. RESULTS: Twelve of the 13 patients were successfully implanted, the success rate of implantation was 92.3%. The median time of neutrophil and platelet engraftment was 12.5 days (range, 9-22 days) and 21 days (range,12-34 days), respectively. One patient achieved primary graft failure. Three (25%) patients developed to acute GVHD (aGVHD) and achieved complete remission after treatment. Chronic GVHD developed in three (25%) patients, one of them was extensive and under treatment, while one patient developed to severe bacterial infection (7.7%). CMV viremia was diagnosed in two patients (15.4%). There were no patients developed to CMV disease. Three (23.1%) patients achieved EB viremia after transplantation, one of them developed to EBV-related lymphocytic proliferative disease, while there were no patients showed invasive fungal infection. At the last follow-up, all patients survived, twelve of them were free from transfusion dependency. There were no transplant-related deaths. Projected overall and thalassemia-free survival at three years was 100% and 92.3%, respectively. CONCLUSION The transplant protocol of haplo-HSCT by using parental donors in patients with thalassemia has reliable source of donors, high incidence of successful implantation and low incidence of GVHD, which can be used as an effective way to increase the source of donors in children with thalassemia.

OBJECTIVE: To investigate the difference of therapeutic effects on children with thalassemia at different age after hematopoietic stem cell transplantation. METHODS: The clinical data of children with thalassemia treated in our hospital were retrospectively analyzed. The children were divided into 2-5 years old group and 6-12 years old group. The success rate of implantation, transplant-related mortality, GVHD incidence, and other transplant-related complications, as well as thalassemia-free survival (TFS) were compared between the two groups. RESULTS: The incidence of GVHD, hemorrhagic cystitis and severe oral mucositis after transplantation in the 2-5 years old group were significantly lower than those in the 6-12 years old group, while there was no statistically significant difference in the TFS between the two groups. CONCLUSION Children in the low age (2-5 years old) group show fewer complications and higher quality of life after transplantation, therefore, stem cell transplantation at 2-5 years old is more conducive to rehabilitation of the children with thalassemia.

Qingxin Lianzi Yin （QXLZY）， as an ancient classical formula for clearing the heart and nourishing the Yin， was composed of nine herbs （Scutellariae Radix， Ophiopogonis Radix， Lycii Cortex， Plantaginis Semen， Glycyrrhizae Radix et Rhizoma Praeparata Cum Melle， Nelumbinis Semen， Poria， Astragali Radix and Ginseng Radix et Rhizoma）， coming from Prescriptions of the Bureau of Taiping People's Welfare Pharmacy. It could clear away the heart-fire， promote the interaction of the heart and kidney， replenish Qi and Yin， and stop strangury-turbidity. It was used to treat gonorrhea of urination， seminal emission， restlessness， wasting-thirst and so on. At present， the usage and dosage of QXLZY and its addition and subtraction are different in clinical practice. Most of the studies just focus on its clinical efficacy， and there is few review literature reflecting its historical evolution. Based on this， this paper systematically clarified the historical evolution， composition， preparation， interpretation， function， and modern clinical application of QXLZY. This work has been explained the historical evolution of QXLZY， and found that it was wildly used in modern clinical， especially suitable for the treatment of chronic urinary system diseases. At the same time， QXLZY also had significant therapeutic effects on neurasthenia， stomatitis， diabetic nephropathy and other aspects. Through the comprehensive analysis of ancient and modern literature， this work explores the true connotation of QXLZY from the perspective of traditional Chinese medicine theory， which can point out the direction of the clinical application and positioning of this famous classical formula after it comes into the market， and also can provide reference basis for its subsequent in-depth research and development.

Caveolin-1 (CAV-1) is related to inflammation, oxidative damage, and immunity. In order to obtain a series of dibenzoylmethane halophenols with strong anti-inflammatory and antioxidant effects targeting CAV-1, twenty-nine target compounds were therefore synthesized by Baker-Ventaraman rearrangement and demethylation reaction, starting from the substituted benzoyl chloride and o-hydroxyacetophenone, and their interactions with CAV-1 were investigated by BLI technique. Their in vitro anti-inflammatory and antioxidant properties were also evaluated. The results showed that compounds A6, A17, A18, and A29 not only specifically bind to CAV-1, but also present strong anti-inflammatory and antioxidant effects. These results suggest that this class of compounds can affect the signaling pathways related to inflammation and oxidative stress by directly acting on CAV-1. In particular, these compounds exhibit the most significantly inhibitory effects on IL-1β and COX-2 release. IL-1β plays a key regulatory role in the development of arthritis. Therefore, it is worth expecting for the application of such compounds in the prevention and treatment of arthritis.

OBJECTIVE: To the clinical characteristics and prognostic value of the patients with complete deletion of TET_JBP domain (ΔJBP) in TET2 acute myeloid leukemia (AML). METHODS: Next Generation Sequencing technology was used to determine the mutations of 34 AML-related genes (including TET2 gene). The I-TASSER tool was used to predict the tertiary structure of the full-length TET2 protein and TET_JBP structure deletion. RESULTS: Among 38 AML patients with TET2 mutations, 22(57.9%) showed truncation mutations, of which 16 (72.7%) produced TET2ΔJBP truncation mutants. Protein structure prediction showed that the deletion of TET_JBP domain lead to the significant changes of tertiary structure in TET2 protein. Compared with the patients in non-ΔJBP group, the age of patients in ΔJBP group were older (63 vs 54 years old, P=0.047), and the occurrence rate of CEBPA double mutation (CEBPA CONCLUSION AML patients with TET2ΔJBP truncation mutant shows lower CR rate, shorter EFS and OS after induction chemotherapy, which may be related to the poor prognosis, and co-mutation with CEBPA
