This article presents a case study of a patient who visited the Geriatric Department of Peking Union Medical College Hospital due to "palpitations, shortness of breath for more than 2 years, limb weakness for 6 months, edema, and nocturnal dyspnea for 2 months". The patient exhibited decreased muscle strength in the limbs and involvement of swallowing and respiratory muscles, alongside complications of heart failure and various arrhythmias which were predominantly atrial. Laboratory tests revealed the presence of multiple autoantibodies and notably anti-mitochondrial antibodies. Following a comprehensive multidisciplinary evaluation, the patient was diagnosed with anti-mitochondrial antibody-associated inflammatory myopathy. Treatment involved a combination of glucocorticoids and immunosuppressants, along with resistance exercises for muscle strength and rehabilitation training for lung function, resulting in significant improvement of clinical symptoms. The case underscores the importance of collaborative multidisciplinary approaches in diagnosing and treating rare diseases in elderly patients, where careful consideration of clinical manifestations and subtle abnormal clinical data can lead to effective interventions.

Roxadustat is the world's first small molecule hypoxia-inducible factor prolyl hydroxylase inhibitor. Its adverse effect of causing hypothyroidism with low thyroid-stimulating hormone (TSH) is relatively rare and manifests subtly in elderly patients with multiple coexisting diseases. This article reports a case of an elderly patient with renal anemia who developed reversible low-TSH hypothyroidism after taking roxadustat for 12 days, with a significant decrease in thyroid hormone levels. After discontinuing roxadustat for 15 days, the thyroid hormone levels gradually returned to normal. Due to the worsening of renal anemia, the patient took roxadustat again, and 9 days later, the thyroid function-related indicators decreased upon re-examination, leading to the initiation of levothyroxine replacement therapy. In conjunction with relevant literature, this article analyzes the adverse reactions that occur during the oral administration of roxadustat in elderly patients with chronic kidney disease, aiming to provide reference for drug treatment of such patients.

To describe the history, current status and development trend of clinical pharmacist training in China.

The writing of pharmacist-managed clinics documents （hereinafter referred to as “outpatient medication record”） is a necessary part of pharmacist-managed clinics service. Outpatient medication record is an important carrier to reflect the quality of pharmacist-managed clinics service. The Chinese Hospital Association Pharmaceutical Specialized Committee was entrusted by the Pharmaceutical Administration Department of the National Health Commission to lead the formulation of the Guidelines for the Pharmacist-managed Clinics Service and Document Writing and Usage （Reference） （hereinafter referred to as Guidelines） according to the compilation method of group standards and the technical route of “documentation combing→framework establishment→draft writing→opinion collection→Guidelines formation”. The Guidelines standardizes the basic requirements of pharmacist-managed clinics record management and the basic content of record， and provides a general template and two specialized templates including pregnant and lactating pharmacist-managed clinics record template and cough and asthma pharmacist-managed clinics record template， which provides a reference for medical institutions to write pharmacist-managed clinics record. This paper introduces the formulation process of Guidelines and analyzes the key contents of Guidelines， which is helpful for the application practice of Guidelines and further improves the quality of pharmacist-managed clinics work.

Liver regeneration following injury aids the restoration of liver mass and the recovery of liver function. In the present study we investigated the contribution of megakaryocytic leukemia 1 (MKL1), a transcriptional modulator, to liver regeneration. We report that both MKL1 expression and its nuclear translocation correlated with hepatocyte proliferation in cell and animal models of liver regeneration and in liver failure patients. Mice with MKL1 deletion exhibited defective regenerative response in the liver. Transcriptomic analysis revealed that MKL1 interacted with E2F1 to program pro-regenerative transcription. MAPKAPK2 mediated phosphorylation primed MKL1 for its interaction with E2F1. Of interest, phospholipase d2 promoted MKL1 nuclear accumulation and liver regeneration by catalyzing production of phosphatidic acid (PA). PA administration stimulated hepatocyte proliferation and enhanced survival in a MKL1-dependent manner in a pre-clinical model of liver failure. Finally, PA levels was detected to be positively correlated with expression of pro-regenerative genes and inversely correlated with liver injury in liver failure patients. In conclusion, our data reveal a novel mechanism whereby MKL1 contributes to liver regeneration. Screening for small-molecule compounds boosting MKL1 activity may be considered as a reasonable approach to treat acute liver failure.

Objective:To study the distribution of TCM constitutions in maintenance hemodialysis (MHD) patients.Methods:This is a multicenter cross-sectional study. The general clinical data, dialysis-related parameters and physical and chemical examination data of MHD patients from 6 dialysis centers in Sichuan were collected. At the same time, DS01-A tongue and facial pulse information collection system was used for TCM constitution discrimination.Results:A total of 232 MHD patients were enrolled , and 417 kinds of TCM constitutions were detected, including 59 patients (25.43%) with moderate constitution and 173 patients (74.57%) with biased constitution. Phlegm-dampness was the most common type of solid constitution 47 patients (20.26%). The most common deficiency constitution was qi deficiency 86 patients (37.07%). There were certain differences in the physical distribution of patients with different gender, age, dialysis age, BMI, and whether they had diabetes, hypertension or anemia.Conclusions:The TCM constitutions of MHD patients are mainly biased constitution. Gender, age, BMI, diabetes or hypertension have a certain impact on the distribution of TCM constitutions. At the same time, different constitutions may have an impact on the anemia of MHD patients. The intervention of TCM constitutions on MHD patients may be beneficial to the prognosis of MHD patients.

OBJECTIVE To provide a reference for the implementation and high-quality development of hospital medication reconciliation. METHODS A semi-structured questionnaire was designed to investigate the implementation of drug reconciliation services in medical institutions before and after the release of 5 standards such as Standard for Medication Reconciliation Services in Medical Institutions（“standards” for short，in 2021 and 2022）. Descriptive statistical analysis was conducted on the survey results. RESULTS After the promulgation of the standards， the medication reconciliation service rate of all types of medical institutions increased from 15.10% （434/2 874） in 2021 to 27.84%（363/1 304） in 2022. In 2022， in the 363 medical institutions providing drug reconciliation services， the median number of pharmacists involved in drug reconciliation was 6. The participation rate of pharmacists in standardized training for drug reconciliation services was 75.00%， among which the participation rate of third-class hospitals was higher， reaching 85.71%. The main stages covered by medication reconciliation services included patient admission， transfer between departments， and discharge. The main problems found in the service included repeated medication （252， 69.42%）， inappropriate usage and dosage （228， 62.81%）， drug interactions and adverse reactions （218， E-mail：cputianxin@163.com 60.06%）. Only 69 institutions （19.01%） had a separate electronic information recording system， while 48 institutions 58516003。E-mail：zhenjiancun@vip.163.com （13.22%） had established comprehensive quality management and evaluation improvement systems. In terms of value embodiment， 141 institutions （38.84%） did not provide any form of compensation to relevant pharmacists. “Closely linked to enhancing patient satisfaction and improving services” was the most significant experience influencing medication reconciliation work（192， 52.89%）， while “the shortage of talent which meet the relevant requirements” stands as the primary challenge faced by medical institutions at all levels（238， 65.56%）. CONCLUSIONS The release of the standards has effectively improved the development rate of medication reconciliation in national medical institutions. However， there is still room for improvement in various aspects， including the allocation of personnel for medication reconciliation services， service content， information management， and the construction of quality control and evaluation systems.

Continuous inflammatory response and repeated tissue damage lead to a chronic inflammatory state that is an important pathological feature of chronic refractory wounds, and plays an important pathogenic role in the occurrence and development of chronic refractory wounds. Multiple types of programmed cell death can release damage-associated molecular patterns, and trigger or induce sustained inflammatory responses, leading to dysregulated tissue repair. This review will outline the known role of programmed cell death in the inflammatory response of chronic refractory wounds from the perspective of generating damage-associated molecular patterns, and explore possible research directions on the role and mechanism of programmed cell death in chronic refractory wounds.

Diffusion weighted imaging is an important imaging technique for diagnosing and evaluating the effectiveness of disease treatment,mainly focusing on the overall diffusion behavior of water molecules but ignoring the microscopic movement of water molecules and the details of tissue microstructures.Combining oscillatory gradient spin-echo and pulsed gradient spin echo sequences,time-dependent diffusion MRI(td-dMRI)captured diffusion MRI signals at varying time,in order to obtain information of different microstructures,which had recently emerged into clinical application with the advancements of hardware.The principles of td-dMRI technology and its application progresses in tumors were reviewed in this article.
