In recent years, survival rate of patients with severe brain injury has been improved with the development of emergency care skills, yet disorders of consciousness (DoC) patients still have poor outcome and need prolonged life support, burdening the families and society. There are still deficiencies in precise diagnosis, individualized treatment and end-of-life decision-making. Based on this, we give the following propositions: promoting multimodal assessment to reduce misdiagnosis; developing individualized plans based on assessment results, stratifying and managing patients at acute or chronic phases, classifying and managing patients with different consciousness levels, improving the legal and ethical framework, scientifically assessing end-of-life decisions, and implementing comprehensive care with multidisciplinary collaboration to enhance DoC patients' quality of life.

Objective:To investigate the selection of treatment methods for renal tumors in pilots as well as the clinical significance of robot-assisted surgery by summarizing the process of robot-assisted surgery in the treatment of renal cell carcinoma in a pilot.Methods:The diagnosis, robot-assisted surgery and aeromedical assessment of a pilot with renal cell carcinoma were reported, and the related literature was reviewed.Results:The patient was a 44-year-old male transporter pilot, who was diagnosed with a left renal mass in the middle-lower pole of the kidney during a routine abdominal CT scan. After detailed preoperative evaluation that ruled out the possibility of distant metastasis and other surgical contraindications, the patient underwent robot-assisted laparoscopic partial nephrectomy in August 2022. The postoperative recovery went well, and renal function remained within normal limits at follow-ups. In March 2023, the pilot was concluded as qualified for flight after aeromedical assessment.Conclusions:Robot-assisted partial nephrectomy can significantly reduce surgical trauma, lower the risk of complications, and maximally preserve renal function. It is a good approach to renal tumors in pilots who can recover quickly.

OBJECTIVE To explore the implementation and standardized management of infection control core ele-ments in grass-roots medical institutions within county-level medical communities.METHODS From Mar.2024 to Apr.2024,the current status of implementation of infection control core elements in the grass-roots medical institu-tions within county-level medical communities was investigated by means of questionnaire survey and qualita-tive interview,and the implementation strategies were further explored.RESULTS The infection management or-ganizational system and functions of the two county-level medical institutions within the county medical communi-ties were completed,there is no independent hospital infection management department in the primary medical in-stitutions.The infection management personnel in the 16 grass-roots medical institutions were part-time person-nel,the personnel with the educational background below junior college accounted for 84.21％,the personnel with the professional background of nursing accounted for 100.00％,the personnel with less than 5 years of working experience accounted for 78.95％,none of them had an on-the-job training certificate.The monitoring programs of the county-level medical institutions within the county medical communities were completed,there was no infec-tion management monitoring information platform in the grass-roots medical institutions.The infection cases,hand hygiene,environmental health and occupational exposures were monitored by people.The grass-roots medi-cal institutions had the highest requirements for various professional trainings and increase of training contents of prevention and control of public health infectious diseases(100.00％).The county-level medical institutions had inadequate capabilities of professional examination of medical equipment replacement and construction of medi-cal architecture.CONCLUSION It is necessary for the country and local levels of governments to attach great importance to the implementation of the infection control core elements in the grass-roots medical institutions within the county-lev-el medical communities,establish the county-level regional information platform,formulate the corresponding surveil-lance indexes and homogenized management systems,complete the cultivation of talents,and offer financial support.

Objective:To explore the genetic etiology for a child with Progressive external ophthalmoplegia with mitochondrial DNA deletions, autosomal dominant 6 (PEOA6).Methods:A child who had attended the Women and Children′s Hospital Affiliated to Ningbo University on 7 August, 2023 was selected as the study subject. Clinical data of the child were analyzed retrospectively. The child and her parents were subjected to whole exome sequencing (WES), and candidate variant was verified by Sanger sequencing and bioinformatic analysis. This study was approved by Medical Ethics Committee of the Women and Children′s Hospital Affiliated to Ningbo University (Ethics No. EC2020-048).Results:The child, a 7-year-old female, had presented with limb muscle pain, amyosthenia, significantly increased creatine kinase, congenital diaphragmatic hernia and recurrent respiratory tract infections. WES revealed that she has harbored a heterozygous c. 1590G>C (p.L530F) variant of the DNA2 gene, which was verified to have a de novo origin by Sanger sequencing. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the c.1590G>C was rated as a likely pathogenic variant (PS2+ PM2_Supporting+ PP3). Conclusion:The c.1590G>C (p.L530F) variant of the DNA2 gene probably underlay the PEOA6 in this child.

Consciousness disorders following traumatic brain injury (TBI) are alterations in consciousness due to damage to the brain parenchyma and/or brain vessels. As the number of TBI patients continues to increase, so does the number of patients with consciousness disorders following TBI. The patients′ quality of life was seriously affected due to a long course of illness and loss of most of independence. However, at present, the mechanisms of consciousness disorders in TBI are still unknown. The assessment of conscious state in patients with consciousness disorders following TBI mainly depends on scales, resulting in a high rate of misdiagnosis. Common interventions, including pharmacological interventions such as amantadine and zolpidem, as well as non-pharmacological interventions such as neuromodulation and sensory stimulation programs, fail to achieve extensive efficacy. Therefore, there is an urgent need for more accurate assessment indicators as well as effective therapeutic interventions. Various neurophysiological activities sustained by sleep are crucial for consciousness. Sleep regularity is likely to reflect the conscious state of patients with consciousness disorders following TBI. Sleep regularity is generally reflected through sleep architecture, including circadian rhythms and various sleep characteristics. Therefore, the authors reviewed the research progress in the application of sleep architecture in the assessment and recovery of conscious state in patients with consciousness disorders following TBI, so as to provide reference for its clinical application.

Immunoglobulin (IgG) glycosylation affects the effector functions of IgG in a myriad of biological processes and has been closely associated with numerous autoimmune diseases, including systemic lupus erythematosus (SLE), thus underlining the pathogenic role of glycosylation aberration in autoimmunity. This study aims to explore the relationship between IgG sialylation patterns and lupus pregnancy. Relative to that in serum samples from the control cohort, IgG sialylation level was aberrantly downregulated in serum samples from the SLE cohort at four stages (from preconception to the third trimester of pregnancy) and was significantly associated with lupus activity and fetal loss during lupus pregnancy. The type I interferon signature of pregnant patients with SLE was negatively correlated with the level of IgG sialylation. The lack of sialylation dampened the ability of IgG to suppress the functions of plasmacytoid dendritic cells (pDCs). RNA-seq analysis further revealed that the expression of genes associated with the spleen tyrosine kinase (SYK) signaling pathway significantly differed between IgG- and deSia-IgG-treated pDCs. This finding was confirmed by the attenuation of the ability to phosphorylate SYK and BLNK in deSia-IgG. Finally, the coculture of pDCs isolated from pregnant patients with SLE with IgG/deSia-IgG demonstrated the sialylation-dependent anti-inflammatory function of IgG. Our findings suggested that IgG influences lupus activity through regulating pDCs function via the modulation of the SYK pathway in a sialic acid-dependent manner.

In order to standardize the quality control of traditional Chinese medicine（TCM） dispensing granules， the Chinese Pharmacopoeia Commission has promulgated and implemented 200 national drug standards for TCM dispensing granules， but there are still varieties of TCM dispensing granules without unified standards. Many provinces have actively invested in the formulation of provincial standards for TCM dispensing granules to make up for the gaps in standards for varieties of traditional Chinese medicine dispensing granules other than the national standards. By the end of July 2022， 29 provincial-level administrative regions have successively promulgated and implemented a total of 5 602 provincial standards for TCM dispensing granules， involving more than 400 varieties. In order to better understand the formulation and characteristics of provincial standards， this study took 105 provincial standards that have been promulgated and implemented in Henan province as an example， and comprehensively analyzed the formulation and characteristics through quality control indicators such as dry extract rate of raw materials， contents of index components and their transfer rates， specifications and so on. The formulation and characteristics of the same TCM dispensing granules in the provincial standards of different provinces were further analyzed， in order to provide reference for the formulation of provincial standards of TCM dispensing granules and the implementation of national standards.
