Mycophenolic acid (MPA), the active moiety of both mycophenolate mofetil (MMF) and enteric-coated mycophenolate sodium (EC-MPS), serves as a primary immunosuppressant for maintaining solid organ transplants. Therapeutic drug monitoring (TDM) enhances treatment outcomes through tailored approaches. This study aimed to develop an evidence-based guideline for MPA TDM, facilitating its rational application in clinical settings. The guideline plan was drawn from the Institute of Medicine and World Health Organization (WHO) guidelines. Using the Delphi method, clinical questions and outcome indicators were generated. Systematic reviews, Grading of Recommendations Assessment, Development, and Evaluation (GRADE) evidence quality evaluations, expert opinions, and patient values guided evidence-based suggestions for the guideline. External reviews further refined the recommendations. The guideline for the TDM of MPA (IPGRP-2020CN099) consists of four sections and 16 recommendations encompassing target populations, monitoring strategies, dosage regimens, and influencing factors. High-risk populations, timing of TDM, area under the curve (AUC) versus trough concentration (C₀), target concentration ranges, monitoring frequency, and analytical methods are addressed. Formulation-specific recommendations, initial dosage regimens, populations with unique considerations, pharmacokinetic-informed dosing, body weight factors, pharmacogenetics, and drug‍-‍drug interactions are covered. The evidence-based guideline offers a comprehensive recommendation for solid organ transplant recipients undergoing MPA therapy, promoting standardization of MPA TDM, and enhancing treatment efficacy and safety.

Objective To retrospectively evaluate the clinical efficacy and safety of brentuximab vedotin(BV) combined with chemotherapy in the treatment of malignant lymphoma. Methods We collected the data of 32 lymphoma patients with CD30-positive status, including 14 cases of Hodgkin's lymphomas, 2 cases of diffuse large B-cell lymphomas, and 16 cases of mature T/NK cell lymphomas. Chemotherapy combined with BV was administered to all patients for a minimum of two cycles. The efficacy of the treatment was evaluated according to Lugano criteria every two cycles. Results Complete response rate and overall response rate after four cycles of treatment were 22% and 50%, respectively. Sixteen cases (50.0%) had grades 1 and 2 toxicity, and 16 cases (50.0%) had grade 3 toxicity or higher. The most common adverse events were neutropenia (50.0%), pneumonia (46.9%), and anemia (43.8%). The most common grade 3 or higher adverse events were pneumonia (18.8%) and febrile neutropenia (12.5%). Four patients discontinued brentuximab vedotin because of severe adverse events. Conclusion BV is effective in treating relapsed and refractory CD30- positive Hodgkin's lymphoma and peripheral T-cell lymphoma, and its overall safety is acceptable.

Objective:To investigate the clinical efficacy of transnasal low-flow oxygen therapy after noninvasive mechanical ventilation in the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) complicated by type II respiratory failure.Methods:This study is a retrospective study. A total of 200 patients with AECOPD complicated by type II respiratory failure who received treatment in The First People's Hospital of Huzhou from January 2021 to March 2023 were selected as the research subjects through the health management platform of The First People's Hospital of Huzhou. These patients were divided into a control group and an observation group ( n = 100 per group) according to the treatment methods. The control group received noninvasive mechanical ventilation but without transnasal low-flow oxygen therapy. The observation group received noninvasive mechanical ventilation and transnasal low-flow oxygen therapy. The anti-inflammatory factors (interleukin 10 and transforming growth factor-beta) and pro-inflammatory factors (tumor necrosis factor-alpha and interleukin 6) were measured by enzyme-linked immunosorbent assay in both groups. Oxygen pressure and carbon dioxide pressure were compared between the two groups before and after treatment. The relief and disappearance time of symptoms such as fever, difficulty in breathing, palpitations, and difficulty in coughing were compared between the two groups. Statistical analysis was performed using IBM SPSS 26.0 software. Results:After treatment, the interleukin-10 level in the control group was (21.45 ± 7.02) ng/L, which was significantly lower than (26.77 ± 9.40) ng/L in the observation group ( t = 4.54, P < 0.001). The interleukin-6 level in the control group was (25.56 ± 8.58) ng/L, which was significantly higher than (18.98 ± 5.78) ng/L in the observation group ( t = 6.37, P < 0.001). Oxygen pressure in the control group was (71.41 ± 5.91) mmHg (1 mmHg = 0.133 kPa), which was significantly lower than (93.69 ± 4.45) mmHg in the observation group ( t = 30.09, P = 0.004). Carbon dioxide pressure in the control group was (43.85 ± 2.99) mmHg, which was significantly higher than (37.87 ± 4.48) mmHg in the observation group ( t = 11.10, P < 0.001). The time to fever relief in the control group was (6.59 ± 1.51) days, which was significantly longer than (6.13 ± 1.19) days in the observation group ( t = 2.39, P = 0.008). The time to dyspnea relief in the control group was (5.61 ± 2.17) days, which was significantly longer than (4.47 ± 1.73) days in the observation group ( t = 4.10, P = 0.021). Conclusion:Noninvasive mechanical ventilation combined with transnasal low-flow oxygen therapy exhibits good therapeutic effects on inflammation control, symptom relief, and pulmonary function recovery in patients with AECOPD combined with type II respiratory failure.

Objective:To explore the effects of hospital-to-community model-based case management on outcomes and life quality of patients with atrial fibrillation.Methods:By convience sampling method, a total of 90 cases of atrial fibrillation patients admitted to Changzhou Second People′s Hospital from January 2019 to May 2020 were randomly divided into control group and experimental group, with 45 cases in each group.

Objective To investigate the effect of flash glucose monitoring (FGM) on ambulatory glucose profile of only oral antidiabetic drugs treated patients with type 2 diabetes mellitus. Methods Twenty-eight type 2 diabetic mellitus patients with only oral antidiabetic drugs treatment from August 2017 to January 2018 were enrolled. All the patients were exposed to FGM for 14 d without changing the original treatment and encouraged to manage self-behavior by adjusting diet and activity based on the blood glucose data obtained from the real-time scanning. The changes in glucose profile during the FGM period were observed, including estimated glycated hemoglobin (HbA1c), standard deviation of blood glucose, variable coefficient of blood glucose, mean amplitude of glycemic excursions, time in range (blood glucose 3.9 to 10.0 mmol/L), area under the curve hyperglycemia (blood glucose> 10.0 mmol/L) and area under the curve hypoglycemia (blood glucose<3.9 mmol/L). The blood glucose levels on second day and thirteenth day were used as baseline and end point respectively. Results All of the 28 patients did not change their anti-diabetic drug therapy and there were no adverse events occurred. The estimated HbA1c was significantly lower than the baseline HbA1c: (6.90 ± 1.48)% vs. (7.57 ± 1.35)%, and there was statistical difference (P = 0.004). The standard deviation of blood glucose, variable coefficient of blood glucose, mean amplitude of glycemic excursions, area under the curve hyperglycemia and area under the curve hypoglycemia at end were significantly lower than those at baseline: (2.07 ± 0.86) mmol/L vs. (2.44 ± 0.86) mmol/L, 0.26 ± 0.11 vs. 0.30 ± 0.11, (5.32 ± 2.75) mmol/L vs. (6.76 ± 3.06) mmol/L, 265 (0, 1 310) vs. 351 (107, 2 177) and 0 (0, 0) vs. 0 (0, 19), the time in range at end was significantly higher than that at baseline: (1 069 ± 386) min vs. (921 ± 449) min, and there were statistical differences (P＜0.05 or＜0.01). The rate of scanning was (12.92 ± 4.87) times/d. Conclusions FGM could be applied by type 2 diabetic mellitus patients to make self-glycemic management without changing therapy, reduce the estimated HbA1c,and hypoglycemia, and improve the glucose fluctuations, which may result from real-time scanning to find abnormal glycemia and adjust daily behavior.

Objective: To investigate the effect of construction of trauma care center on the treatment of patients with severe multiple trauma. Methods: A retrospective case control study was conducted to analyze the clinical data of 412 patients with severe multiple trauma admitted to the First Affiliated Hospital of Soochow University from December 2015 to November 2017. There were 250 males and 162 females, aged 19-80 years [(45.8±15.9)years]. The injury severity score (ISS) ranged from 18 to 57 points [(28.2±9.3)points]. The observation group included 211 patients who were treated after the establishment of the provincial trauma treatment center in Jiangsu Province, and the control group included 201 patients who were treated before the establishment of the provincial trauma treatment center. The durations from arrival to the start of rescue, from consultation to completion of CT examination, from applying for blood transfusion to the execution of blood transfusion by nurses, the time of stay at the resuscitation room and the mortality rate were compared between the two groups. Results: The observation group presented better results in the durations from arrival to the start of rescue [(2.5±1.7)minutes vs. (5.4±2.6)minutes], from the start of the rescue to completion of CT scan [(36.2±11.6)minutes vs. (53.2±12.9)minutes], the transfusion time [(28.7±11.3)minutes vs. (46.5±14.1)minutes], and the time of stay at resuscitation room [(3.0±2.0)hours vs. (5.0±2.8)hours] (P<0.05 or 0.01). The mortality rate in the observation group was 3.8% (8/211), which was significantly lower than 8.5% (17/201) in control group (P<0.05). Conclusion The construction of trauma treatment center can effectively shorten the treatment time of patients with severe multiple trauma, reduce the mortality rate and improve the efficacy, which is worthy of promotion.
