Clinical pathway has great similarity with DRG,and plays an important role in standardizing diagnosis and treatment behavior and controlling medical expenses.Based on the analysis of the relationship between DRG payment method reform and clinical pathway,taking a public hospital in Wuhan City,Hubei Province as an example,the clinical pathway implementation strategy of large public hospitals under the DRG payment method reform was explored from five aspects:management system,suitable disease types,doctor's order setting,information system,training and assessment.

The medical teams assessment under the chief physician responsibility system is conducive to promoting the high-quality development and refined management of public hospitals. In October 2022, Union Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology carried out the practice of medical team assessment, including five dimensions of service ability, service efficiency, technical ability, cost control and quality and safety. By setting the assessment indicators and their weights for each medical team in a classified manner, clarifying the implementation methods of the assessment, and rationally applying the assessment results, initial achievements had been made. In 2022, the number of medical teams, case mix index, proportion of effective medical service income, and proportion of discharged patients undergoing surgery in the hospital were 395, 1.63, 28.93%, and 31.60%, respectively. By 2023, these data increased to 447, 1.92, 30.74%, and 32.47%. The average length of stay and the intensity of antibiotic use decreased from 7.3 days and 35.15 to 6.4 days and 35.15. This medical team assessment helped enhance the hospital′s medical service capacity, improved the structure of medical income, and improved medical quality, providing references for other public hospitals to carry out medical team assessment.

Objective:This study aimed to retrospectively analyze the clinical characteristics and prognosis of patients with acute leukemia in the plateau.Methods:The clinical information of patients diagnosed with acute leukemia from February 2010 to April 2023 at the People's Hospital of Tibet Autonomous Region was reviewed and collected, including blood cell count, morphology, immunophenotype, cytogenetics, and molecular data. Survival analysis was conducted to analyze the outcome of patients with acute leukemia.Results:This study enrolled 105 patients with acute leukemia, including 24 with acute lymphoblastic leukemia (ALL), 62 with acute myeloid leukemia (AML), and 19 with acute leukemia without baseline data. Of the patients with ALL, 11 underwent bone marrow testing for immunophenotype, all of whom were B-cell lineage. The main FAB subtype of patients with AML was M 2 (25/57), followed by M 3 (12/57), M 5 (6/57), M 4EO (5/57), M 1 (4/57), M 4 (4/57), and M 0 (1/57). The complete remission rates of patients with ALL, acute promyelocytic leukemia (APL), and AML (non-APL) after one course of induction therapy were 57.1% (8/14), 100% (6/6), and 53.6% (15/28), respectively. The median event-free survival (EFS) and overall survival (OS) for patients with ALL were 2 (95% CI 0-9) and 3 (95% CI 0-9) months, respectively, with a median followup of 37 (95% CI 17-57) months. Patients with APL did not reach median EFS or OS, whereas the median EFS and OS for core binding factor AML (CBF-AML) cases were 10 (95% CI 0-21) months and 13 (95% CI 3-23) months, respectively, and patients with non-CBF-AML had inferior median EFS (2 months, 95% CI 1-3) and OS (2 months, 95% CI 1-3) ( P<0.01). Patients with ALL treated from 2020 to 2023 demonstrated trends toward better EFS ( P=0.16) and OS ( P=0.10) than those treated from 2010 to 2019. Similarly, trends toward superior EFS ( P=0.27) and OS ( P=0.12) were observed in patients with AML treated from 2016 to 2023, in comparison with those treated from 2010 to 2015. Conclusion:Progress in the treatment and prognosis of patients with acute leukemia in the plateau has been observed in recent years, which can be further promoted by precision diagnosis and tailored regimens.

Chemogenetic technology is a receptor-ligand system that regulates cell viability and function by changing receptor specificity and affinity, and it achieves precise neuronal regulation by specifically regulating neurons and neural circuits. At present, this technique is widely used in the study of neural circuits. This article briefly describes the application and progress of chemogenetic technology in the study of depression neural circuits, reviews the application of chemogenetic technology in several brain regions closely related to depression, such as ventral tegmental area, nucleus accumbens, prefrontal cortex, hippocampus and lateral habenula, and discusses the potential and challenges of chemogenetic technology as a technology for precise regulation of neural activity in future research, in order to provide reliable ideas and directions for chemogenetic technology in the study of depression neural circuits.

Optogenetic technique is a cellular activity regulation technology that combines optics and genetics, which can specifically regulate the relevant brain regions and neural circuits in depressive animal models, thereby slowing down or aggravating depression-like behaviors in experimental animals. Optogenetic technique combined with neuroimmunoassay, behavioral detection and brain imaging techniques can provide technical support for elucidating the pathogenesis of depression, developing new antidepressants and diagnosis and treatment methods. In this paper, the application of optogenetic technique in the ventral tegmental area, nucleus accumbens, prefrontal cortex, hippocampus, dorsal raphe nucleus and other brain regions closely related to depression is reviewed to provide ideas and directions for study of neural circuits of depression.

A young female patient with acne and elevated testosterone level underwent plasma steroid hormones testing and found a significant increase in aldosterone. We excluded testing interference and verified the absence of hypertension, hypokalemia, and adrenal occupancy, as well as primary and secondary hyperaldosteronism. During follow-up, a temporal correlation was found between aldosterone levels and the use of drospirenone and ethinylestradiol tablets. It was observed that the combination of drospirenone and ethinylestradiol could lead to the increase of aldosterone level and the concentration ratio of aldosterone to direct renin through different mechanisms. Drospirenone exerts an antagonistic effect on mineralocorticoid receptor to prevent the development of hypertension or hypokalemia. In clinical practice, it is necessary to pay attention to the effect of this drug on screening markers for primary aldosteronism. In the laboratory examination, when female patients with no symptoms of hypertension and hypokalemia but with elevated aldosterone levels are encountered, it can be verified whether they have a history of use of compound estrogen-progestin such as drospirenone and ethinylestradiol tablets, and appropriate tips are provided in the report.
