ObjectiveTo evaluate the clinical effectiveness and safety of Modified Zhigancao Granules （炙甘草汤加味颗粒） for preventing the early recurrence following radiofrequency ablation in patients with atrial fibrillation （AF） of qi-yin deficiency syndrome. MethodsA multi-center， randomized， double-blind， placebo-controlled trial was designed. A total of 116 patients with atrial fibrillation of qi-yin deficiency syndrome who underwent radiofrequency ablation for the first time were enrolled from 3 centers， and they were randomly divided into a treatment group （59 cases） and a control group （57 cases）. Both groups received basic western medicine treatment after surgery. In addition， the treatment group was given oral Modified Zhigancao Granules， while the control group was given oral placebo granules. The dosage for both groups was 20 g each time， twice a day， with continuous treatment for 12 weeks. The recurrence of atrial fibrillation in both groups was recorded at 24 hours， 4 weeks， 8 weeks， and 12 weeks after surgery. The serum levels of B-type natriuretic peptide （BNP）， interleukin-6 （IL-6）， high-sensitivity C-reactive protein （hs-CRP）， and tumor necrosis factor-α （TNF-α） were detected before treatment and 12 weeks after treatment in both groups. The scores of Atrial Fibrillation Effect on QualiTy-of-life （AFEQT） Questionnaire （including scores of the daily life dimension， symptom dimension， treatment worry dimension， treatment satisfaction dimension， and total score） and traditional Chinese medicine （TCM） syndrome scores were compared before treatment and at 4 weeks， 8 weeks， and 12 weeks between groups. Safety indicators such as blood routine， urine routine， liver function， and renal function were monitored before and after treatment. ResultsNine of the treatment group and seven of the control group dropped out. Finally， 50 patients in each group were included in the statistical analysis. At 24 hours， 4 weeks， 8 weeks， and 12 weeks after surgery， the recurrence rates of AF in the treatment group were 2.0% （1/50）， 2.0% （1/50）， 4.0% （2/50）， and 10.0% （5/50）， respectively； while those in the control group were 2.0% （1/50）， 26.0% （13/50）， 28.0% （14/50）， and 34.0% （17/50）， respectively. Compared with the control group at the same time points， the early recurrence rates of AF in the treatment group were significantly lower at 4 weeks， 8 weeks， and 12 weeks after surgery （P＜0.01）. Compared with the baseline within group， BNP， hs-CRP， IL-6， and TNF-α in the treatment group all decreased after 12 weeks of treatment （P＜0.05）； the difference in hs-CRP levels （before vs. after treatment） in the treatment group was higher than that in the control group （P＜0.01）. Compared with the baseline within group， both groups showed decreases in the total score of AFEQT Questionnaire， scores of the daily life dimension， treatment worry dimension， symptom dimension， and TCM syndrome scores at 4 weeks， 8 weeks， and 12 weeks after treatment. Meanwhile， the score of the treatment satisfaction dimension of AFEQT increased in both groups （P＜0.01）， and the improvements in all the above scores in the treatment group were superior to those in the control group at all time points （P＜0.05 or P＜0.01）. All safety indicators of patients in both groups were within the normal range before treatment and at 12 weeks after treatment， and no adverse reactions or adverse events occurred in either group. ConclusionModified Zhigancao Granules can reduce the early recurrence rate following radiofrequency ablation in AF patients with qi-yin deficiency syndrome， improve clinical symptoms and quality of life， suppress inflammatory response， and show good safety.

Psoriasis, a chronic, immune-mediated inflammatory disease characterized by hyperproliferation of keratinocytes, is difficult to cure and prone to relapse, often leading to systemic damage. Triptolide (TPL) can modulate cutaneous immune responses and inflammation, yet its therapeutic window is narrow with significant toxicity. To enhance skin targeting and retention of TPL while reducing systemic absorption and toxicity, a TPL/hyaluronic acid/phospholipid polymeric micelle (TPL/HA-DOPE) was constructed via HA's targeting of the CD44 receptor on skin cells. The prepared TPL/HA-DOPE exhibited a uniform spherical morphology with particle size of (130.4±1.23) nm, drug loading capacity of (19.74±0.084) %, and encapsulation efficiency of (85.53±1.34) %. Transdermal permeation studies in vitro and in vivo demonstrated that TPL/HA-DOPE not only enhanced uptake in HaCaT cells but also exhibited excellent skin retention. In a murine model of psoriasis, the TPL/HA-DOPE gel at the dose of 50 μg/(kg•d) showed the most significant improvement in erythema, scaling, and epidermal thickening. Histological analysis confirmed that TPL/HA-DOPE markedly reduced stratum corneum thickness, epidermal hyperplasia, and inflammatory cell infiltration. Ki67 immunostaining proved that its anti-inflammatory mechanism might be achieved by reducing the number of Ki67-positive cells and lowering the levels of inflammatory factors IL-6 and TNF-α. The above results demonstrate that HA-DOPE as a drug delivery carrier for the treatment of psoriasis-like skin diseases has high value of scientific research and good prospects for clinical application.

Objectives:To investigate the efficacy of short-term substitution of recombinant humanized anti-CD25 monoclonal antibody (Basiliximab) as acute GVHD (aGVHD) prophylaxis in calcineurin inhibitors (CNI) intolerant patients following allogeneic hematopoietic stem cell transplantation (allo-HSCT) .Methods:This study included 17 patients with refractory malignant hematological disorders who underwent salvage allo-HSCT at the Bone Marrow Transplantation Department of Shanghai Zhaxin Traditional Chinese and Western Medicine Hospital from August 2021 to August 2022 and were treated with Baliximab to prevent aGVHD due to severe adverse reactions to CNI. There were seven men and ten women, with a median age of 43 years (18-67). Following the discontinuation of CNI, Basiliximab was administered at a dose of 1 mg/kg once weekly until CNI or mTOR inhibitors were resumed.Results:Basiliximab was started at an average of 5 (1-32) days after HSCT. The median duration of substitution was 20 (7-120) days. All had neutrophil engraftment within a median of 12 (10-17) days. Thirteen patients had platelet engraftment after a median of 13 (11-20) days. Four patients did not develop stable platelet engraftment. Eight patients (47.1% ) developed Grade Ⅱ-Ⅳ aGVHD, while four (23.6% ) developed Grade Ⅲ/Ⅳ aGVHD. Only one patient died from aGVHD. Before the end of the followup period, seven of 17 patients died. The longest followup period of the survivors was 347 days, and the median survival rate was not met. The overall survival (OS) rate at six months was 62.6%. Among the 17 patients, 13 (76.4% ) experienced cytomegalovirus reactivation, 7 (41.2% ) experienced EB virus activation, and no cytomegalovirus disease was observed.Conclusions:When CNI intolerance occurs during allo-HSCT, short-term replacement with Baliximab can be used as an alternative to prevent aGVHD.

A retrospective analysis was conducted on three patients with primary myelofibrosis who underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) at Shanghai Zhaxin Traditional Chinese and Western Medicine Hospital from 2020 to 2023. They subsequently developed poor graft function. The patients received selected donor CD34 + cell boosts as salvage therapy. There were two male patients and one female patient, with a median age of 68 (39-69) years. The median time from allo-HSCT to the selected donor CD34 + cell boost was 83 (56-154) days. The median infusion of selected donor CD34 + cells was 7.67 (7.61-9.06) ×10 6/kg, with a CD34 + cell purity of 97.76% (96.50%-97.91%) and a recovery rate of 70% (42%-75%) . Hematological recovery was achieved in two cases. No acute GVHD was observed in any of the three patients. One case of moderate oral chronic GVHD was noted. Selected donor CD34 + cell boosts for the treatment of poor graft function after allo-HSCT in primary myelofibrosis was effective and no severe acute or chronic GVHD was observed.

Objective Reliability and validity of the Chinese version of disability attitude scales(DAS-CN)toward disabled persons were created and tested to provide an assessment instrument for measuring the attitude of medical staff toward disabled persons in China.Methods Authorised by the author of DAS in August 2020,based on BRISLIN translation model,the English version of DAS was translated into Chinese followed by back translation,cultural debugging and then put it into pre-experiment in September 2020.The reliability and validity of the finalised DAS-CN were further tested in a survey with 400 randomly selected medical staff in rehabilitation from 8 general hospitals in Jinzhou,Panjin,Yingkou and Fushun in Liaoning Province,China by using the convenience sampling method in March 2021.Results A total of 357 surveyees completed the survey.The localised DSA-CN was composed of 4 dimensions with a total of 20 items,including 4 items in clinical knowledge and skills,4 in clinical responsibility,8 in clinical behaviour and 4 in emotional response.The Cronbach α coefficient of the scales was 0.943,with the split-half reliability and test-retest reliability at 0.824 and 0.899,respectively.The Cronbach α coefficient of each dimension was 0.843～0.944,and the split half reliability was 0.854～0.904.The test-retest reliability ranged from 0.701 to 0.913.The KMO value of exploratory factor analysis was 0.921.The Bartrett spherical test value was 5534.981(P<0.01).The total explanatory rate of variation was 73.050%.Conclusion The Chinese version of Disability Attitude Scales(DSA-CN)has good reliability and validity.Therefore,DSA-CN can be used as an instrument in investigation of the current status about the attitudes towards the disabled persons among the medical staff in China.

Objective:To evaluate the clinical outcomes and safety of haploidentical hematopoietic stem cell transplantation (haplo-HSCT) using a conditioning regimen based on total body irradiation (TBI) and rabbit anti-human thymocyte globulin (rATG) in the management of chemotherapy-resistant advanced peripheral T-cell lymphoma (PTCL) .Methods:Clinical data of 11 patients with chemotherapy-resistant advanced PTCL who underwent haplo-HSCT with a TBI+rATG-based conditioning regimen at the Department of Hematology, Shanghai Liquan Hospital and Shanghai Zhaxin Integrated Traditional Chinese and Western Medicine Hospital, from September 2019 to December 2022 were retrospectively analyzed.Results:①Among the 11 patients (six males and five females), with a median age of 40 years (range: 22-58 years), there were six cases of PTCL, not otherwise specified (PTCL-NOS), three cases of angioimmunoblastic T-cell lymphoma (AITL), one case of large-cell transformation of mycosis fungoides (MF-LCT), and one case of T-cell large granular lymphocytic leukemia (T-LGLL). According to the Lugano staging system, all patients were in stage Ⅲ or Ⅳ, and eight patients had B symptoms. Before transplantation, the median number of prior lines of chemotherapy was 4 (range: 2-10), and all patients had progressive disease (PD). The median time from diagnosis to transplantation was 17 months (range: 6-36 months). ②The conditioning regimen consisted of a TBI dose of 10 Gy, administered at 2 Gy on day -8 and 4 Gy from day -7 to day -6, rATG was administered at a daily dose of 2.5 mg/kg from day -5 to day -2. Etoposide (VP-16) was given at a dose of 15 mg/kg/d from day -5 to day -4, while cyclophosphamide (CTX) was administered at a dose of 50 mg/kg/d from day -3 to day -2. In patients with central nervous system involvement, etoposide and cyclophosphamide were replaced with thiotepa (TT) at a dose of 5 mg/kg/d from day -5 to day -4. Additionally, cytarabine (Ara-C) was added at a dose of 2.0 g/m 2 twice a day from day -3 to day -2 into the conditioning. ③Successful engraftment was achieved in all patients, with a median time to neutrophil engraftment of 14.5 d (range: 11-16 d) and a median time to platelet engraftment of 13 days (range: 8-18 days). Acute graft-versus-host disease (aGVHD) occurred in one patient (grade Ⅰ-Ⅱ), and another patient experienced grade Ⅲ-Ⅳ aGVHD. Among the eight survivors, four developed chronic GVHD (cGVHD). ④Post-transplantation, nine patients achieved complete response (CR). ⑤Hematopoietic suppression occurred in all patients after conditioning, with three experiencing diarrhea, four developing mucositis, three exhibiting elevated transaminase/bilirubin levels, and seven developing infectious complications. These non-hematologic adverse events were effectively managed. ⑥At one year post-transplantation, the non-relapse mortality (NRM) was (22.5±14.0) %, the cumulative incidence of relapse (CIR) was (20.2±12.7) %, and overall survival (OS) rate was (72.7±13.4) %, and disease-free survival (DFS) rate was (63.6±14.5) % . Conclusion:TBI+rATG-based conditioning regimen for haplo-HSCT is an effective and safe treatment approach for patients with chemotherapy-resistant advanced PTCL.

Objective:To explore the effect of early essential newborn care technology during cesarean section on early health outcomes of mothers and infants and breast feeding.Methods:This study was a randomized controlled study. From October 2020 to August 2021, 104 delivery women and their newborns who were scheduled for full-term cesarean section in Peking University First Hospital were selected as the study subject. The subjects were randomly divided into control group and intervention group, 52 cases in each group. The control group received routine nursing of the newborn after cesarean section, while the intervention group received early essential newborn care technology after cesarean section. The amount of postpartum hemorrhage, hospital stay, Apgar score at one and five minutes after birth, the incidence of abnormal conditions within 90 minutes after birth, the time of umbilical cord shedding, the time of the first feeding sign of the newborn, the success rate of early initiation of breastfeeding and the implementation of breast feeding at discharge were compared between the two groups.Results:There was no statistical difference between the two groups in the amount of postpartum hemorrhage within two hours, the amount of postpartum hemorrhage within two to 24 hours and the number of days in hospital ( P>0.05) . There was no statistical difference between the two groups in Apgar scores at one and five min after birth ( P>0.05) . There was no statistical difference between the two groups in the occurrence of re-attraction, respiratory abnormalities, resuscitation, Neonatal Intensive Care Unit (NICU) transfer and other abnormalities within 90 minutes after birth ( P>0.05) . There was no statistical difference in the time of umbilical cord shedding between the two groups ( P>0.05) , and no umbilical infection occurred. The first foraging reflex in the intervention group was earlier than that in the control group, and the success rate of early initiation of breastfeeding was higher than that in the control group, and the differences was statistically significant ( P<0.05) . There was no statistical difference in the implementation of breast feeding between the two groups at discharge ( P>0.05) . Conclusions:It is safe and feasible to implement early essential newborn care technology during cesarean section, and it can effectively promote early initiation of breastfeeding, which is of great significance for breast feeding and has the value of clinical promotion.

Background::The APPEC study is a large-population randomized controlled trial in China evaluating the role of low-dose aspirin prophylactic treatment for pre-eclampsia. There was no statistically significant difference in postpartum hemorrhage (PPH) incidence between the aspirin and control groups. This study aimed to evaluate the potential bleeding risk of 100 mg aspirin in high-risk pregnant women and the difference in the incidence of PPH according to maternal characteristics.Methods::This is a secondary data analysis of the APPEC study. Platelet counts and coagulation test results were collected at five follow-up visits. Subgroups defined by maternal age (<35 years and ≥35 years), pre-pregnancy body mass index (pre-BMI, <28 kg/m 2 and ≥28 kg/m 2), parity, gestational age at enrollment, and medical history, including pre-eclampsia, chronic hypertension, and diabetes mellitus, were analyzed. Logistic regression analysis was used to determine the statistical significance of the difference in the incidence of PPH after aspirin administration in pregnant women in each subgroup. Adjustment using multiple logistic regression models followed these analyses. Binary logistic regression was used to determine the relationship between pre-BMI and PPH. Results::There was no significant difference between the aspirin and control groups in bleeding risk (3.4% [16/464] vs. 3.0% [13/434], T = 0.147, P = 0.701). No significant difference was found in the incidence of PPH in total (relative risk = 1.220, 95% confidence interval [CI] = 0.720–2.067, P = 0.459; aspirin group vs. control group, 6.5% [30/464] vs. 5.3% [23/434], P = 0.459) or in subgroup analysis. A significant correlation between pre-BMI and PPH was found in the aspirin group, while in the control group there was no significant correlation (aspirin group, odds ratio [OR] = 1.086, 95% CI = 1.004–1.175, P = 0.040; control group, OR= 1.060, 95% CI = 0.968–1.161, P = 0.209). Conclusions::A dosage of 100 mg of aspirin per day, initiated from 12 to 20 gestational weeks until 34 weeks of gestation, did not increase the risk of potential bleeding and PPH regardless of the maternal characteristic. In the aspirin group, the positive correlation between BMI and PPH was significant.Trial Registration::ClinicalTrials.gov, NCT01979627.

ObjectiveTo compare the diagnostic accuracy of five different weighting methods of Chinese medicine syndrome and then analyze their diagnostic efficacy and characteristics， by taking Diagnostic Standard for Type 2 Diabetes Mellitus （T2DM） with Dampeness-heat Syndrome （abbreviated as diagnostic standard） as an example. MethodsData from expert questionnaire on the diagnostic standard and a cross-sectional survey of 1021 patients were collected. The comparative diagnostic test accuracy （CDTA） method was used to calculate the area under the ROC curve （AUC）， area under the PR curve （AUPR）， accuracy （ACC）， sensitivity， and specificity of five commonly used weighting methods in two categories， including knowledge-driven weighting methods （expert scoring synthesis method， analytic hierarchy process， and precedence chart method） and data-driven weighting methods （logistic regression contribution method and entropy weighting method）. ResultsAmong 1021 patients with T2DM， 389 cases were diagnosed as dampness-heat syndrome. The expert scoring synthesis method， analytic hierarchy process method， and precedence chart method were basically consistent in the weight scores of each item. The expert scoring comprehensive method， analytic hierarchy process method， and entropy weighting method have a smaller difference in the weight scores of each item， while there was larger difference in the weight scores of each item of the precedence chart method and the logistic regression contribution method. The AUC （95% CI）， AUPR， ACC， sensitivity， and specifi-city of the expert scoring synthesis method were 0.913 （0.893， 0.932）， 0.851， 0.870， 0.868 and 0.875， respectively； while those of the analytic hierarchy process method were 0.910 （0.890， 0.930）， 0.838， 0.879， 0.848 and 0.896； of the precedence chart method were 0.919 （0.900， 0.937）， 0.858， 0.875， 0.871 and 0.875； of the logistic regression contribution method were 0.867 （0.842， 0.891）， 0.792， 0.853， 0.769 and 0.898； and of the entropy weighting method were 0.895 （0.873， 0.916）， 0.820， 0.869， 0.802 and 0.908. ConclusionThe knowledge-driven weighting methods are better than the data-driven weighting methods in terms of diagnostic efficacy and reflecting expert experience.

Objective:To explore the efficacy and safety of blinatumomab in treatment of relapsed/refractory B-cell acute lymphoblastic leukemia (B-ALL).Methods:The data of 8 patients with relapsed/refractory B-ALL treated with blinatumomab in Shanghai Zhaxin Traditional Chinese and Western Medicine Hospital from September 2020 to December 2021 were retrospectively analyzed, and their clinical characteristics, overall survival, lymphocyte subsets, cytokines, tandem transplantation and adverse reactions were analyzed.Results:The median follow-up time of 8 patients was 143 d (range: 41-534 d). Five of the 8 patients were alive; among them, 4 of 6 patients assessed to be in minimal residual disease (MRD)-negative complete remission (CR) and 1 of 2 patients assessed to be in non-remission at the time of belintuzumab discontinuation were alive. The median duration of treatment with belintuzumab was 28 d (10-56 d), and it was 23 d (10-56 d) for patients with MRD-positive at baseline and 28 d (25-31 d) for the 4 non-remission patients. Six patients achieved MRD-negative CR after treatment, of which 4 were assessed as MRD-positive at baseline and 2 were assessed as non-remission at baseline. All 4 patients with MRD-positive CR achieved MRD-negative CR after treatment with belintuzumab, including 1 patient with Philadelphia chromosome-positive (Ph +) ALL bridged to autologous hematopoietic stem cell transplantation, and 1 patient with Ph + ALL and 1 patient with Ph - ALL received sequential allogeneic hematopoietic stem cell transplantation and had persistent MRD-negative CR. Two of the 4 non-remission patients achieved MRD-negative CR after treatment with belintuzumab, including 1 patient with Ph + ALL bridged to autologous hematopoietic stem cell transplantation, and 1 patient with Ph - ALL received sequential allogeneic hematopoietic stem cell transplantation, and the 2 patients had persistent MRD-negative CR. Leukocyte counts and neutrophils decreased in both MRD-positive CR and non-remission patients after receiving belintumomab. The proportion and absolute number of CD3 + T and CD3 + CD8 + T lymphocytes in patients with MRD-positive CR were higher than those in patients without remission, and both decreased after drug administration. Median interleukin-6 (46.23, 1.42 pg/ml), interleukin-8 (17.85, 2.10 pg/ml), interleukin-10 (7.43, 1.49 pg/ml) and interferon-γ (11.82, 0.39 pg/ml) levels were elevated in MRD-positive CR and non-remission patients at week 3 of treatment. Grade 1 cytokine release syndrome occurred in 1 case with clinical manifestations of fever, which improved after drug suspension. Three cases developed infections, 2 of which were pulmonary and 1 of which was upper respiratory tract infection. No immune effector cell-associated neurotoxic syndrome was observed. Conclusions:Belintumomab is effective for MRD clearance in relapsed/refractory B-ALL with manageable adverse reactions, providing an effective therapeutic option for bridging hematopoietic stem cell transplantation to prolong the survival of patients.
