Radiochemotherapy-induced oral mucositis (OM) is a common oral complication in patients with tumors following head and neck radiotherapy or chemotherapy. Erosion and ulcers are the main features of OM that seriously affect the quality of life of patients and even the progress of tumor treatment. To date, differences in clinical prevention and treatment plans for OM have been noted among doctors of various specialties, which has increased the uncertainty of treatment effects. On the basis of current research evidence, this expert consensus outlines risk factors, clinical manifestations, clinical grading, ancillary examinations, diagnostic basis, prevention and treatment strategies and efficacy indicators for OM. In addition to strategies such as basic oral care, anti-inflammatory and analgesic agents, anti-infective agents, pro-healing agents, and photobiotherapy recommended in previous guidelines, we also emphasize the role of traditional Chinese medicine in OM prevention and treatment. This expert consensus aims to provide references and guidance for dental physicians and oncologists in formulating strategies for OM prevention, diagnosis, and treatment, standardizing clinical practice, reducing OM occurrence, promoting healing, and improving the quality of life of patients.

Objective:To develop a treatment-related quality of life scale for Chinese patients with multiple myeloma (MM) and to test its reliability and validity.Methods:The initial scale was constructed through a literature search, Delphi expert correspondence, and cognitive testing. This study conducted a preliminary survey of 379 patients with MM and a formal survey of 865 patients from the hematology departments of 155 hospitals nationwide from February 2024 to March 2024. The final scale was obtained after conducting item analysis and reliability and validity tests on the initial scale.Results:The constructed scale contains 36 items covering six domains: physiological, psychological, social, treatment side effects, general health, and others. In the preliminary survey, the Cronbach’s alpha coefficient of each item ranged from 0.597 to 0.939, and the test-retest reliability was 0.747 ( P<0.001). Exploratory factor analysis extracted eight common factors with a cumulative variance contribution of 60.058%. In the formal survey, the Cronbach’s alpha coefficient of each item ranged from 0.484 to 0.930, and the test-retest reliability was 0.835 ( P<0.001). Confirmatory factor analysis revealed a comparative fit index of 0.750, a root-mean-square error of approximation of 0.090, and a root-mean-square residual of 0.067. Conclusion:The treatment-related quality of life scale for Chinese patients with MM designed in this study exhibited good reliability and validity, reflecting the impact of treatment on the quality of life of patients. This scale can provide a reference to clinicians for assessing the disease status of patients.

From August 2019 to July 2024, the Institute of Chest Wall Surgery at the Affiliated Guangdong Second Provincial General Hospital of Jinan University admitted multiple patients with severe thoracic deformities. Authors summarized the characteristics and treatment measures of three cases with typical acute-angled thoracic deformities. Three patients aged from 15 to 21 year-old were suffered from severe pectus excavatum, pectus carinatum, and complex thoracic deformities, respectively. Visually, the local bones were severely distorted, and CT scans showed that the local bones formed acute-angled intersections. Three patients underwent Wung surgery, Wenlin surgery, and Wang+ Wenlin surgery. During the operation, based on pre-shaping, the principle of template shaping was applied to implement correction, and the process was uneventful. All deformities were satisfactorily corrected. There were no postoperative complications such as bleeding, pneumothorax, or poor wound healing during 8 months to 4 years of follow-up. Acute angle deformity is a special type of thoracic deformity, and its occurrence often indicates that the local deformity is severe and complex. Therefore, in treatment, surgeons are required to first understand the basic principle of thoracic deformity correction, have a strong comprehension of the overall deformity, and be skillful and experienced in applying various thoracic deformity correction techniques.

Objective To explore the current situation of the clean operating rooms in Guangdong provincial hospitals of traditional Chinese medicine or integrated Chinese and western medicine to provide references for standardizing the construc-tion of the clean operating room.Methods A questionnaire was designed according to GB 50333-2013 Architectural technical code for hospital clean operating department and WS/T 368-2012 Management specification of air cleaning technique in hospitals,and a questionnaire survey and field investigation were conducted from March to October 2021 on the operating rooms of 64 secondary and above hospitals of traditional Chinese medicine or integrated Chinese and western medicine in Guangdong province,which involved in the basic situation of the operating rooms,general requirements for constructing clean operating rooms,requirements for the layout of clean operating rooms and architectural decorations of the clean operating rooms.Results Of the 64 hospitals surveyed there were 51 ones(79.7％)with clean operating rooms.Tertiary hospitals were mainly equipped with Class Ⅲ clean operating rooms(45.8％),secondary hospitals were provided with general operating rooms(35.0％)and Class Ⅲ clean operating rooms(29.2％),and the differences in the types and classes of the operating rooms in levels of hospitals were statistically significant(P＜0.001).The proportions of tertiary hospitals configured with clean operating rooms and the highest configuration of Class I clean operating rooms were also significantly higher than those of secondary hospitals(94.3％vs 62.1％and 88.6％vs 44.8％,respectively),with statistically significant differences(P＜0.05).There were 66.7％hospitals equipped with negative pressure operating rooms;more than 1/2(56.9％)of the hospitals had the service time of their clean operating rooms longer than 10 years.All the tertiary hospitals did not have air shower rooms in their walkways,while 16.7％secondary hospitals did,with the difference being statistically significant(P＜0.05).Most of the building decorations of clean operating rooms in all the hospitals complied with the specifications(compliance rate＞80.0％),and the difference was not statistically significant between the secondary and tertiary hospitals(P＞0.05);the compliance rate of the decrations of the tertiary hospitals was 78.8％for the requirements of general principle,which was obviously lower than that of the secondary hospitals(100％),with the differences being statistically significant(P＜0.05).Conclusion The clean operating rooms in Guangdong provincial hospitals of traditional Chinese medicine or integrated Chinese and western medicine behave well in configuration,while have some defficiencies in general requirements,layout and building,and necessary guidance,supervision and management have to be involved in to standardize the construction of clean operating rooms.[Chinese Medical Equipment Journal,2024,45(10):77-83]

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To establish the "1+3" management module of high-value consumables in Operation Room and verify its application, so as to provide new ideas for cost management of consumables in Operation Room.Methods:The Operating Room team of Shenzhen Hospital of Southern Medical University designed a "1+3" management module in 2022, where "1" referred to the management process of high-value consumables in Operation Room, and "3" referred to the precise management of consumables in Operation Room warehouse, the management of closed-loop use of Operation Room consumables and adverse event management of consumables. Surgeries using high-value consumables in the Thoracic Surgery Department, Gastrointestinal Surgery Department, and Urology Department of the hospital were selected as the research objects. The surgeries using conventional consumables from January to June 2022 were set as the control group, and the surgeries implementing the "1+3" management module from July to December 2022 were set as the observation group. The number of consumables received by the itinerant nurses before the operation and the number of high-value consumables returned after the operation were compared between the two groups. And the number of missed and error charges for high-value consumables in the two groups were counted and compared.Results:The number of consumables received before operation in the control group was higher than that in the observation group, and the difference was statistically significant ( P<0.05). The number of high-value consumables returned in the observation group was less than that in the control group, and the difference was statistically significant ( P<0.01). The proportion of missed charges for consumables in the observation group was lower than that in the control group, and the difference was statistically significant ( P<0.01), but there was no statistically significant difference in the proportion of incorrect charges between the two groups ( P>0.05) . Conclusions:The "1+3" management module for high-value consumables in Operation Room makes the process of receiving, returning, and charging high-value consumables clear, with traceable data, achieving refined management of high-value consumables in Operation Room, reducing the number of high-value consumables returned to the warehouse and reducing the proportion of missed consumables, which is conducive to effective cost control in Operation Room.

Long non-coding RNAs (lncRNAs) play a significant role in maintaining tissue morphology and functions, and their precise regulatory effectiveness is closely related to expression patterns. However, the spatial expression patterns of lncRNAs in humans are poorly characterized. Here, we constructed five comprehensive transcriptomic atlases of human lncRNAs covering thousands of major tissue samples in normal and disease states. The lncRNA transcriptomes exhibited high consistency within the same tissues across resources, and even higher complexity in specialized tissues. Tissue-elevated (TE) lncRNAs were identified in each resource and robust TE lncRNAs were refined by integrative analysis. We detected 1 to 4684 robust TE lncRNAs across tissues; the highest number was in testis tissue, followed by brain tissue. Functional analyses of TE lncRNAs indicated important roles in corresponding tissue-related pathways. Moreover, we found that the expression features of robust TE lncRNAs made them be effective biomarkers to distinguish tissues; TE lncRNAs also tended to be associated with cancer, and exhibited differential expression or were correlated with patient survival. In summary, spatial classification of lncRNAs is the starting point for elucidating the function of lncRNAs in both maintenance of tissue morphology and progress of tissue-constricted diseases.

OBJECTIVES: To study the characteristics of amino acid metabolism in preterm infants in Guangxi, China. METHODS: A retrospective analysis was performed on the medical data of 30 757 neonates who underwent the screening for inherited metabolic diseases and had negative results in Guangxi Neonatal Disease Screening Center from 2018 to 2020. Among these neonates, there were 28 611 normal full-term infants (control group) and 2 146 preterm infants (preterm birth group). According to gestational age, the preterm infants were further divided into four groups: very preterm (n=209), moderately preterm (n=307), and late preterm group (n=1 630). According to birth weight, they were divided into three groups: very low birth weight group (n=161), low birth weight group (n=1 085), and normal birth weight group (n=900). According to blood collection time, they were divided into three groups: 3-7 days group (n=1 664), 8-14 days group (n=314) and 15-28 days group (n=168). Tandem mass spectrometry was performed to measure the levels of 11 amino acids in dried blood spots, which were then compared between groups. RESULTS: After adjustment for confounding factors, there were significant differences in the levels of 11 amino acids among different gestational age groups (P<0.05), and significant differences were observed in the levels of the 11 amino acids between the control group and the various preterm groups (except for citrulline and methionine in the late preterm group). There were significant differences in the levels of 11 amino acids among different birth weight groups (P<0.05). Except for ornithine, there were significant differences in the levels of other amino acids among the different blood collection time groups (P<0.05). CONCLUSIONS Gestational age, birth weight and blood collection time all affect amino acid metabolism in preterm infants in Guangxi, China. This provides a basis for the laboratory to establish the reference standard and clinical interpretation of blood amino acid levels in preterm infants, and to improve the nutritional metabolism of preterm infants.
