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.

This paper reported a type 1 diabetes patient who had severe diabetic nephropathy, retinopathy, hypertension, and hypothyroidism before pregnancy. The patient's blood glucose control was poor before pregnancy, and the complications were not properly treated. This was an unintended pregnancy, with a pre-pregnancy glycated hemoglobin A1c of 7.8% and early pregnancy urine protein of 3.81-4.53 g/24 h. Considering the patient's poor blood glucose control before pregnancy and the lack of proper treatment for multiple complications including nephropathy, a multidisciplinary consultation at an external hospital recommended termination of the pregnancy. However, the patient was determined to continue the pregnancy and was referred to Peking University First Hospital. Through strict blood glucose control, monitoring and evaluation of complications, and comprehensive management, the patient's blood glucose and blood pressure were well controlled during pregnancy. Regular monitoring of urine protein, renal function, and ocular fundus was conducted. At 31 weeks and 4 days of gestation, the patient's 24-hour urine protein significantly increased. After promoting fetal lung maturity, a cesarean section was performed at 34 weeks and 1 day of gestation, resulting in a successful delivery with good maternal and neonatal outcomes. At the 42-day postpartum follow-up, the patient's blood glucose and blood pressure were stable, urine protein returned to pre-pregnancy levels, and the infant was in good general condition.

Background Exposure to polycyclic aromatic hydrocarbons (PAHs) is associated with the development of metabolic syndrome (MS). However, the role of amino acids in PAH-induced MS remains unclear. Objective To explore the impact of PAHs exposure on the incidence of MS among coking workers, and to determine potential modifying effect of amino acid on this relationship. Methods Unmatched nested case-control design was adopted and the baseline surveys of coking workers were conducted in two plants in Taiyuan in 2017 and 2019, followed by a 4-year follow-up. The cohort comprised 667 coking workers. A total of 362 participants were included in the study, with 84 newly diagnosed cases of MS identified as the case group and 278 as the control group. Urinary levels of 11 PAH metabolites and plasma levels of 17 amino acids were measured by ultrasensitive performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Logistic regression was used to estimate the association between individual PAH metabolites and MS. Stratified by the median concentration of amino acids, Bayesian kernel machine regression (BKMR) model was employed to assess the mixed effects of PAHs on MS. Due to the skewed data distribution, all PAH metabolites and amino acids in the analysis were converted by natural logarithm ln (expressed as lnv). Results The median age of the 362 participants was 37 years, and 83.2% were male. Compared to the control group, the case group exhibited higher concentrations of urinary 2-hydroxyphenanthrene (2-OHPhe), 9-hydroxyphenanthrene (9-OHPhe), and hydroxyphenanthrene (OHPhe) (P=0.005, P=0.049, and P=0.004, respectively), as well as elevated levels of plasma branched chain amino acid (BCAA) and aromatic amino acid (AAA) (P<0.05). After being adjusted for confounding factors, for every unit increase in lnv_2-OHPhe in urine, the OR (95%CI) of MS was 1.57 (1.11, 2.26), and for every unit increase in lnv_OHPhe, the OR (95%CI) of MS was 1.82 (1.16, 2.90). Tyrosine, leucine, and AAA all presented a significant nonlinear correlation with MS. At low levels, tyrosine, leucine, and AAA did not significantly increase the risk of MS, but at high levels, they increased the risk of MS. In the low amino acid concentration group, as well as in the low BCAA and low AAA concentration groups, it was found that compared to the PAH metabolite levels at the 50th percentile (P₅₀), the log-odds of MS when the PAH metabolite levels was at the 75th percentile (P₇₅) were 0.158 (95%CI: 0.150, 0.166), 0.218 (95%CI: 0.209, 0.227), and 0.262 (95% CI: 0.241, 0.282), respectively, However, no correlation between PAHs and MS was found in the high amino acid concentration group. Conclusion Amino acids modify the effect of PAHs exposure on the incidence of MS. In individuals with low plasma amino acid levels, the risk of developing MS increases with higher concentrations of mixed PAH exposure. This effect is partly due to the low concentrations of BCAA and AAA.

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:To evaluate the efficacy of visualized precise lung expansion for determining the intersegmental plane in thoracoscopic segmentectomy.Methods:Sixty-four American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ patients, regardless of gender, aged 33-77 yr, with body mass index of 16-34 kg/m 2, undergoing elective thoracoscopic segmentectomy under general anesthesia, were included. They were preoperatively reconstructed with 3D CT bronchovascularization to reconstruct the pulmonary vasculature, bronchus, and the virtual intersegmental planes of the lungs. The patients were divided into 2 groups ( n=32 each) using a random number table method: visualized precise lung expansion group (group V) and modified expansion and atrophy group (group E). Group V used visualized precision lung expansion to determine the intersegmental planes, and group E used the modified expansion and atrophy method to determine the intersegmental planes. The intraoperative intersegmental plane determination time, target segmental bronchus identification and treatment time, anesthesia time, operation time, postoperative air leakage, pulmonary atelectasis, fever, occurrence of lung infection, postoperative 24 h drainage volume, drain removal time and hospitalization time were recorded in the two groups. Results:Compared with group E, the intersegmental plane determination time, target segment bronchial identification and treatment time, anesthesia time and operation time were significantly shortened in group V( P<0.05).There were no significant differences between groups in the 24 h postoperative drainage volume, drain removal time, hospitalization time or incidence of postoperative pulmonary complications ( P>0.05). Conclusions:Compared with the modified expansion and atrophy method, visualized precise lung expansion can effectively shorten the intersegmental plane determination time in thoracoscopic segmentectomy.
