Non-small cell lung cancer (NSCLC) ranks the first among malignant tumors in China and even in the whole world. In recent years, the developement of genetic testing technology, particularly tumor gene sequencing, has provided a solid basis for the clinical molecular diagnosis of NSCLC, which has greatly increased the chances of patients benefiting from targeted therapy or immunotherapy, and ultimately extending their survival. Standardizing the use of tumor gene sequencing is crucial for the precision medicine in NSCLC. This paper discusses the normalization of tumor gene sequencing technology in the clinical molecular diagnostic pathway of NSCLC, which may promote the standardized use of tumor gene sequencing technology in targeted therapy or immunotherapy drug selection, toxicity and side effect prediction, efficacy monitoring, recurrence and prognosis evaluation of NSCLC patients. This article discusses the standardization of the application of tumor gene sequencing technology in the clinical molecular diagnosis pathway of NSCLC. Additionally, it offers a foundation for the uniform use of tumor gene sequencing technology in other solid tumors.

Cadre assessment is an important part of cadre management and should have scientific and credible characteristics. " who assesses" " what to assess" " how to assess" and " how to use the results" have become urgent practical issues that need to be resolved in cadre assessments. By combining analysis of relevant policies and the actual annual assessment work of cadres from 2016 to 2019 at a certain hospital, and using expert consultation and in-depth interviews, a hierarchical and classified annual comprehensive evaluation system for middle-level cadres has been established. This system included both daily assessments and annual assessments, with weights of 10% and 90% respectively; moreover, in the annual assessment, different weights were assigned to the indicators at various levels for middle-level cadres in different positions, highlighting the organizational assessment orientation, emphasizing the performance orientation in medical practice, teaching, research, and management, and focusing on objective achievements. Since 2021, a certain hospital has been using this comprehensive evaluation system, which has further improved the methods for examining and identifying cadres, enhanced the targeting and effectiveness of cadre education and training, strengthened positive incentives for cadres, tightened supervision and management of cadres, and improved the assessment and evaluation mechanisms. This has led to an increase in the quality, capacity, and implementation of job responsibilities within the cadre team, and can provide decision-making reference and work guidance for health administrative departments and other medical institutions.

OBJECTIVE To study the effect and potential mechanism of eriodictyol on non-alcoholic fatty liver disease （NAFLD）. METHODS Sixteen C57BL/6J mice were randomly divided into control group， NAFLD model group， and eriodictyol low-dose and high-dose groups （50， 100 mg/kg）， with 4 mice in each group. Except for control group， the other groups were fed with high fat diet to induce NAFLD model. After four weeks of preprocessing， they were given relevant medicine intraperitoneally （0.01 mL/g）， once a day， for 6 consecutive weeks. The body weight and liver weight of mice were measured， and the pathological damage of liver tissue in mice was observed. The levels of aspartate aminotransferase （AST）， alanine aminotransferase（ALT）， and triglycerides （TG） in serum， as well as the protein expressions of nuclear factor-erythroid 2-related factor 2 （Nrf2） and heme oxygenase-1 （HO-1） in liver tissue were determined. In vitro NAFLD model was established by using 0.5 mmol/L oleic acid （OA） in HepG2 cells. Normal control group， NAFLD model group and eriodictyol low-， medium- and high-concentration groups （50， 100， 150 μmol/L） were set up. HepG2 cells in drug groups were treated with eriodictyol for 24 h at the time of modeling. The lipid deposition was observed in cells， and the levels of TG， malondialdehyde （MDA） and reactive oxygen species （ROS） as well as the phosphorylation levels of the mitogen-activated protein kinase （MAPK） signal pathway related proteins [extracellular signal-regulated kinase （ERK）， c- Jun N-terminal kinase （JNK）] and the protein expressions of Nrf2 and HO-1 were all determined. RESULTS In the in vivo experiment， compared with the NAFLD model group， the body weight， liver weight， the serum levels of AST， ALT and TG were all decreased significantly in eriodictyol low- and high-dose groups （except for serum level of AST in eriodictyol low-dose group） （P＜0.01）； liver lipid deposition was reduced significantly and the protein expressions of Nrf2 and HO-1 in liver tissues were further up-regulated （P＜0.01）. In the in vitro experiment， compared with the NAFLD model group， the lipid deposition in hepatocytes was reduced in eriodictyol low-， medium- and high-concentration groups （P＜0.01）， and the levels of ROS， MDA and TG were down-regulated （P＜0.05 or P＜0.01）； the phosphorylation levels of ERK and JNK were significantly down-regulated （P＜0.01）， while the protein expressions of Nrf2 and HO-1 were up-regulated significantly （P＜0.01）. CONCLUSIONS Eriodictyol can inhibit MAPK signaling pathway and activate Nrf2/HO-1 signaling pathway to alleviate NAFLD.

Infectious bone defect is bone defect with infection or as a result of treatment of bone infection. It requires surgical intervention, and the treatment processes are complex and long, which include bone infection control,bone defect repair and even complex soft tissue reconstructions in some cases. Failure to achieve the goals in any step may lead to the failure of the overall treatment. Therefore, infectious bone defect has been a worldwide challenge in the field of orthopedics. Conventionally, sequestrectomy, bone grafting, bone transport, and systemic/local antibiotic treatment are standard therapies. Radical debridement remains one of the cornerstones for the management of bone infection. However, the scale of debridement and the timing and method of bone defect reconstruction remain controversial. With the clinical application of induced membrane technique, effective infection control and rapid bone reconstruction have been achieved in the management of infectious bone defect. The induced membrane technique has attracted more interests and attention, but the lack of understanding the basic principles of infection control and technical details may hamper the clinical outcomes of induced membrane technique and complications can possibly occur. Therefore, the Chinese Orthopedic Association organized domestic orthopedic experts to formulate An evidence-based clinical guideline for the treatment of infectious bone defect with induced membrane technique ( version 2023) according to the evidence-based method and put forward recommendations on infectious bone defect from the aspects of precise diagnosis, preoperative evaluation, operation procedure, postoperative management and rehabilitation, so as to provide useful references for the treatment of infectious bone defect with induced membrane technique.

Objective: To understand the parenting styles of junior high school students in Beijing, to explore the relationship between parenting styles with students academic performance and the role of mental health in this association. Methods: From October 2019 to January 2020, a stratified random cluster sampling method was used to select 5 196 students in the first and second grades of 11 public junior high schools in urban and rural areas in Beijing, and Slort Egna Minnenar Barndoms Uppfostran-China,Middle School Students Mental Health Scale-60 and self designed questions were used in the questionnaire survey. Results: The average score of parenting style rejection dimension was (9.44±3.88), and the average score of emotional warmth dimension was (19.85±5.66). The average score of comprehensive score of students mental health was ( 1.92 ±0.73). Mental health score of girls was higher than boys (1.97±0.74)(1.87±0.71), and the differences were of statistical significance( t=5.06, P <0.01). Parental rejection and emotionally warm parenting styles were significantly correlated with students academic performance （ β =-0.54，1.15， P <0.01). Mental health played a negative moderating role between parenting style and students academic performance. The better students mental health were, the greater the influence of parenting style on academic performance. Conclusion Parenting style is related to children s academic performance. Parents should give their children more affirmation, encouragement and praise, in order to improve their academic performance.

Upholding the overall leadership of the Party is an important cornerstone for promoting development of public hospitals. Party building leadership for high-quality development of public hospitals must adhere to the value orientation of public welfare, establish a modern hospital management system, and promote the mutual promotion and integration of both Party building and medical service. The practice path of Party building in leading the high-quality development of public hospitals in a tertiary hospital won the support of patients, employees and medical students at large, gave full play to the leading role of the Party, and made breakthroughs in terms of medical service, discipline construction, talent training and internal management quality improvements. By strengthening top-level design and institutional system construction, the hospital has effectively transformed the political and organizational advantages led by Party building into an endogenous momentum for the reform and development of public hospitals. The practice solved such important questions as to the beneficiaries of the high-quality development of public hospitals, whom to depend on and how to govern, hence providing reference for further promoting the high-quality development of public hospitals in China and realizing the deep integration of Party building and medical service.

Based on observing the cytological characteristics of the flower buds of the functional male sterile line (S13) and the fertile line (F142) in eggplant, it was found that the disintegration period of the annular cell clusters in S13 anther was 2 days later than that of F142, and the cells of stomiun tissue and tapetum in F142 disintegrated on the blooming day, while it did not happen in S13. The comparative transcriptomic analysis showed that there were 1 436 differential expression genes (DEGs) (651 up-regulated and 785 down-regulated) in anthers of F142 and S13 at 8, 5 days before flowering and flowering day. The significance analysis of GO enrichment indicated that there were more unigene clusters involved in single cell biological process, metabolism process and cell process, and more catalytic activity and binding function were involved in molecular functions. Through KEGG annotation we found that the common DEGs were mainly enriched in the biosynthesis of secondary metabolites, metabolic pathway, protein processing in endoplasmic reticulum, biosynthesis of amino acids, carbon metabolism and plant hormone signal transduction. The fifteen genes co-expression modules were identified from 16 465 selected genes by weighted gene co-expression network analysis (WGCNA), three of which (Plum2, Royalblue and Bisque4 modules) were highly related to S13 during flower development. KEGG enrichment showed that the specific modules could be enriched in phenylpropanoid biosynthesis, photosynthesis, porphyrin and chlorophyll metabolism, α-linolenic acid metabolism, polysaccharide biosynthesis and metabolism, fatty acid degradation and the mutual transformation of pentose and glucuronic acid. These genes might play important roles during flower development of S13. It provided a reference for further study on the mechanism of anther dehiscence in eggplant.

Objective:To explore the morphology and vessel distribution of the scapholunate interosseous ligament and anatomical basis for the clinical reconstruction of scapholunate interosseous ligament.Methods:From October, 2018 to December, 2018, 12 fresh wrist joint specimens were perfused with gelatin-lead oxide solution from ulnar or radial artery and scanned under micro-CT. The morphology of scapholunate interosseous ligament in neutral position and the distribution of nutrient vessels in the ligament were observed on reconstructed 3D images by Mimics. The width, length and thickness of palmar, dorsal and proximal ligaments were measured. The anatomical parameters at the entrance of nutrient vessels in the scapholunate interosseous ligament were taken and their relationship with the blood supply to the scapholunate was analyzed.Results:①For scapholunate interosseous ligament, it was found that the average length of the proximal sub-region was the longest, the length of palmar and dorsal sides was similar to each other and the widest and thinnest was in palmar side, while the thickness and width of dorsal and proximal were similar. ②There was no nutrient vessel in the proximal part of the scapholunate interosseous ligament. But there were abundant nutrient vessels in the palmar and dorsal scapholunate interosseous ligament, and there was no significant difference in blood supply to palmar and dorsal scapholunate interosseous ligament ( P>0.05). ③The palmar and dorsal medial nutrient vessels that supply to the scapholunate interosseous ligament enter the scapholunate from the attachment of ligament of scapholunate interosseous joint. Conclusion:The palmar side of the scapholunate interosseous ligament is wider and thinner than that of the other subareas, which makes it more vulnerable to injury from an anatomical point of view. There is abundant blood supply to the palmar and dorsal subareas of the scapholunate interosseous ligament and the supplying vessels anastomose inside the scapholunate bone. There is no distribution of blood vessel at the proximal part of scapholunate interosseous ligament, hence is difficult to heal. An injury of palmar and dorsal ligaments may affect the blood supply of scapholunate.
