ObjectiveTo describe the medical services quality and safety of rehabilitation medicine departments in general hospitals and rehabilitation hospitals in 2022 from the aspects of structure, link and outcome quality. MethodsThrough the National Clinical Improvement System of the National Health Commission, all secondary and above general hospitals and rehabilitation hospitals were investigated in 2022, the relevant data from 7 250 hospitals, including traditional Chinese medicine hospitals and integrated traditional Chinese and Western medicine hospitals in 2022. A total of 3 153 sampling hospitals that equipped with rehabilitation medicine wards were included for analysis. ResultsAmong the 7 250 general hospitals surveyed this year, only 3 277 equipped with rehabilitation wards. In general hospitals, the average number of physicians per bed in 56.46% hospitals, the average number of rehabilitation therapists per bed in 77.67% hospitals, and the average number of nurses per bed in 51.18% hospitals did not meet the national requirements. The rates of early rehabilitation intervention were 13.98%, 20.82% and 21.36% respectively in the department of orthopedics, department of neurology and department of intensive care in general hospitals. The average activity of daily living improvement rate of discharged patients from rehabilitation departments of general hospitals was 77.69%, and that of discharged patients from rehabilitation specialized hospitals was 66.78%. ConclusionThere are insufficient allocation of wards and facility scales in the department of rehabilitation medicine, a shortage of human resources for rehabilitation services, inadequate integration of rehabilitation services with clinical services, and there is still scope for enhancing the effect and efficiency of rehabilitation services. It is recommended to expand the scale of rehabilitation services and improve discipline construction; increase the quantity and quality of rehabilitation human resources; incorporate rehabilitation services into the health service system; establish and modify clinical rehabilitation guidelines and technical specifications; and construct a rehabilitation medical information platform.

ObjectiveBased on the conjoint analysis of transcriptome and metabolome， the key genes in the phenylpropanoid biosynthesis pathway of Lonicera macranthoides were explored， which provided a basis for further exploring the synthesis and regulation mechanism of phenylpropanoid compounds in "Xianglei" L. macranthoides. MethodsThe stem， leaves， and three flowering flowers of "Xianglei" L. macranthoides were selected as experimental materials to construct transcriptome and metabolome. The transcriptome and metabolomics were conjointly analyzed by the Kyoto Encyclopedia of Genes and Genomes （KEGG） database and weighted correlation network analysis （WGCNA）， and the key genes in the phenylpropanoid biosynthesis pathway of L. macranthoides were explored. ResultsIn this study， 77 differential phenylpropanoids and 315 differential genes were found. Through the joint analysis of transcription and metabolism， nine key differential metabolites and four key genes related to them were finally discovered. Among them， cinnamic acid， 5-O-caffeoylshikimic acid，sinapyl alcohol， and chlorogenic acid were higher in flowers， and the content of the iconic effective component， namely chlorogenic acid，decreased sharply during the withering period. Caffeic acid，ferulic acid， 5-hydroxyconiferaldehyde，p-coumaryl alcohol， and syringin were higher in leaves. These four key genes belong to the cinnamic alcohol dehydrogenase （CAD） family， 4-coumaric acid： Coenzyme A （4CL） family， hydroxycinnamyl transferase （HCT） family， and L-phenylalanine ammonlyase （PAL） family genes. ConclusionAmong the four key genes excavated from L. macranthoides， TRINITY_DN42767_c0_g6 is related to the synthesis of p-coumaryl alcohol and sinapyl alcohol. TRINITY_DN43525_c4_g1 uses caffeic acid，ferulic acid，and cinnamic acid as substrates to catalyze the next reaction. TRINITY_DN47958_c3_g4 correlates with the synthesis of 3-p-coumaroyl quinic acid and caffeoyl-CoA， and TRINITY_DN52595_c1_g2 correlates with cinnamic acid synthesis. These findings provide a basis for further exploring the synthesis and regulation mechanism of phenylpropanoids in "Xianglei" L. macranthoides.

Animal experiments are an essential component of life sciences and medical research. However, the external validity and reliability of individual animal studies are frequently challenged by inherent limitations such as small sample sizes, high design heterogeneity, and poor reproducibility, which impede the effective translation of research findings into clinical practice. Systematic reviews and meta-analysis represent a key methodology for integrating existing evidence and enhancing the robustness of conclusions. Currently, however, the application of systematic reviews and meta-analysis in the field of animal experiments lacks standardized guidelines for their conduct and reporting, resulting in inconsistent quality and, to some extent, diminishing their evidence value. To address this issue, this paper aims to systematically delineate the reporting process for systematic reviews and meta-analysis of animal experiments and to propose a set of standardized recommendations that are both scientific and practical. The article's scope encompasses the entire process, from the preliminary preparatory phase [including formulating the population， intervention， comparison and outcome （PICO） question, assessing feasibility, and protocol pre-registration] to the key writing points for each section of the main report. In the core methods section, the paper elaborates on how to implement literature searches, establish eligibility criteria, perform data extraction, and assess the risk of bias, based on the Preferred Reporting Items for Systematic Reviews and Meta-analysis （PRISMA) statement, in conjunction with relevant guidelines and tools such as Animal Research： Reporting of in Vivo Experiments （ARRIVE) and a risk of bias assessment tool developed by the Systematic Review Centre for Laboratory Animal Experimentation (SYRCLE). For the presentation of results, strategies are proposed for clear and transparent display using flow diagrams and tables of characteristics. The discussion section places particular emphasis on how to scientifically interpret pooled effects, thoroughly analyze sources of heterogeneity, evaluate the impact of publication bias, and cautiously discuss the validity and limitations of extrapolating findings from animal studies to clinical settings. Furthermore, this paper recommends adopting the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology to comprehensively grade the quality of evidence. Through a modular analysis of the entire reporting process, this paper aims to provide researchers in the field with a clear and practical guide, thereby promoting the standardized development of systematic reviews and meta-analysis of animal experiments and enhancing their application value in scientific decision-making and translational medicine.

HDAC7, a member of class IIa HDACs, plays a pivotal regulatory role in tumor, immune, fibrosis, and angiogenesis, rendering it a potential therapeutic target. Nevertheless, due to the high similarity in the enzyme active sites of class IIa HDACs, inhibitors encounter challenges in discerning differences among them. Furthermore, the substitution of key residue in the active pocket of class IIa HDACs renders them pseudo-enzymes, leading to a limited impact of enzymatic inhibitors on their function. In this study, proteolysis targeting chimera (PROTAC) technology was employed to develop HDAC7 drugs. We developed an exceedingly selective HDAC7 PROTAC degrader B14 which showcased superior inhibitory effects on cell proliferation compared to TMP269 in various diffuse large B cell lymphoma (DLBCL) and acute myeloid leukemia (AML) cells. Subsequent investigations unveiled that B14 disrupts BCL6 forming a transcriptional inhibition complex by degrading HDAC7, thereby exerting proliferative inhibition in DLBCL. Our study broadened the understanding of the non-enzymatic functions of HDAC7 and underscored the importance of HDAC7 in the treatment of hematologic malignancies, particularly in DLBCL and AML.

Objective: To understand the current status of tuberculosis prevention and control knowledge and perceived stress among college and middle school students with pulmonary tuberculosis (PTB) in Yantai City, and to analyze the related factors, so as to provide a basis for the school to carry out health education and psychological counseling. Methods: A matched case control study was conducted, with 100 PTB student patients in junior high school and above who were diagnosed at designated medical institutions from October 2020 to October 2024. Four healthy control students of the same gender, same dormitory, or same class were selected for each case. Therefore, 100 cases and 400 controls were investigated by questionnaire. The following information was collected: personal basic information; tuberculosis prevention and control awareness; and scores of the Chinese Perceived Stress Scale (CPSS). Conditional Logistic regression model and mixed linear models were used to compare the PTB prevention and control awareness rate, as well as the perceived stress between the case and control groups. Multiple linear regression analysis was used to analyze the factors that may affect the perceived stress of students with PTB. Results: The awareness rates of four tuberculosis knowledge items (symptoms of PTB, main causes of onset after infection, consequences of PTB patients not receiving standardized and complete treatment, the most important method to prevent PTB) were higher in the case group (40.00%, 72.00% , 38.00%, 49.00%) than the control group (21.50%, 57.50%, 22.25%, 31.25%) and the differences were statistically significant ( Wald χ 2=18.44, 8.78, 13.20, 16.89, all P <0.01). The tension score (10.49±4.20), loss of control score ( 11.21± 4.58), and total score (21.70±6.88) in the case group were higher than the control group (9.35±4.73, 9.75±5.60, 19.09±8.36) and the differences were statistically significant ( t =2.21, 2.42, 2.88, all P <0.05). The results of multiple linear regression analysis showed that age ≥ 18 years and family history of tuberculosis were the related factors affecting the overall perceived stress and tension of college and middle school students with PTB ( B total scores =4.50, 5.91; B tension score =2.39, 3.23, all P <0.05). Conclusions The tuberculosis prevention and control awareness rate, and the perceived stress of college and middle school students with PTB in Yantai are both higher than students without tuberculosis. Moreover, the perceived stress of students with PTB who are aged ≥18 years or have a family history of tuberculosis is even higher.

ObjectiveTo analyze the medical services, quality and safety of rehabilitation medicine departments in general hospitals and rehabilitation hospitals in 2021 in perspectives of structure, segment and outcome quality. MethodsWe analyzed the data from National Clinical Improvement System of the National Health Commission, involving 9 328 hospitals, including all secondary and above general hospitals and rehabilitation hospitals, as well as traditional Chinese Medicine hospitals and integrated traditional Chinese and Western medicine hospitals in 2021. A total of 2 513 sampling hospitals that equipped with rehabilitation wards were included. ResultsAmong the 9 328 general hospitals surveyed this year, only 2 713 had rehabilitation wards. In general hospitals, the average number of physicians per bed in 56.77% hospitals, the average number of rehabilitation therapists per bed in 80.36% hospitals, and the average number of nurses per bed in 53.53% hospitals did not meet the national requirements, and the average number of rehabilitation medical personnel per bed in rehabilitation medicine departments in different regions was significantly different. The rates of early rehabilitation intervention were 13.45%, 20.67% and 29.74% respectively in department of orthopedics, department of neurology and intensive care units in general hospitals. The average improvement rate of activities of daily living of discharged patients was 77.87% in rehabilitation department of general hospitals, and 69.01% in rehabilitation hospitals. ConclusionIn 2021, professional medical services, quality and safety of rehabilitation medicine in China have improved steadily. However, most general hospitals in China still have not configured the rehabilitation wards, and there are problems such as the total number of rehabilitation medical personnel in the country does not meet the requirements, early rehabilitation intervention is significantly insufficient, and the implementation of important evaluation and therapies is deficient. The effect of rehabilitation still needs to improve. It is necessary to continuously promote capacity building of the medical rehabilitation to improve the quality of medical rehabilitation services.

Objective:To investigate effects of short-term cigarette smoke exposure combined with poly(I:C)stimulation on lung immune response and interferon expression in mice.Methods:BALB/c mice were randomly divided into 4 groups:control group,smoke group,poly(I:C)group and smoke combined poly(I:C)group.Total cell number and cell classification count of bronchoalveo-lar lavage fluid(BALF)were detected,and cell morphology was observed under ordinary light.Cytokines,chemokines,interferon and interferon stimulating genes expressions in lung tissues were detected by fluorescence quantitative PCR.Results:Compared with control group,total cell count,macrophage count and neutrophil count in smoke combined poly(I:C)group were significantly increased(P<0.05),and macrophage count was higher than that in poly(I:C)group.Macrophages of airway lavage fluid of mice in smoke combined with poly(I:C)group were larger in size,round or irregular in shape,and had more vacuoles in cytoplasm.Com-pared with control group,mRNA expressions of neutrophil chemokine CXCL1(P<0.05),CXCL2(P<0.01)and lymphocyte chemo-kine CCL2(P<0.01)in lung tissues of mice in smoke combined with poly(I:C)group were increased.IL-1β,IL-6,TNF-α mRNA expressions were significantly increased(P<0.01),IFN-β(P<0.01),IFN-γ(P<0.05),MX2(P<0.01)and IP-10(P<0.01)expre-ssions in lung tissues were significantly increased,and compared with poly(I:C)group,mRNA expressions of CXCL2(P<0.05),TNF-α(P<0.01)and IFN-β(P<0.05)in lung tissues of mice in smoke combined with poly(I:C)group were significantly increased.Conclusion:Cigarette smoke combined with poly(I:C)induces lung inflammation and expressions of interferon and interferon stimu-lating genes in mice.Cigarette exposure also increases poly(I:C)-induced acute lung inflammation and type Ⅰ interferon expression in mice.

Objective Explore differences in the cognitive abilities of socially different Labradors.Methods The dog mentality assessment(DMA)test created by the Swedish Working Dog Association was modified to employ 12 behavioral variables from five subtests of the DMA test,social contact,play Ⅰ,distance-play,ghosts and play Ⅱ,to assess sociability of the dogs.In accordance with the scoring criteria,49 labradors provided by the China Guide Dog Training Centre in Dalian were scored on the social behavioral variables and classified into high(n=15)and low(n=34)sociability groups by cluster analysis.A new system to test canine cognitive ability was developed using the dog cognitive development battery,which tests various domains of cognitive ability such as social cue use,unsolvable task,inhibitory control,cognitive flexibility,working memory,and multistep problem solving task.The dogs'behavioral performance and duration of the test were also recorded.Statistical analysis was performed to determine assess differences in the cognitive abilities of socially diverse dogs.Results Dogs in the high and low social subgroups differed significantly in behavioral variables of the unsolvable task,inhibitory control test,and multistep problem solving task.In the unsolvable task,dogs in the high social group looked at people for significantly longer than dogs in the low social grouping(P=0.008)and looked at people with significantly less latency time than dogs in the low social group(P=0.0001).In the inhibitory control,dogs in the high social group chose significantly more correctly than dogs in the low social group(P=0.034)and chose for significantly less time than dogs in the low social group(P=0.039).In the multistep problem solving task,for dogs in the high social group.successfully completed number of stakes was significantly higher than for dogs in the low social group(P=0.044).The percentage of operation pale time was significantly lower than for dogs in the low social group(P=0.05).The average latency time to solve the bone task was significantly higher than for dogs in the low social group(P=0.037).Moreover,the percentage of operation bone time was significantly lower than for dogs in the low social group(P=0.038).In tests involving a manipulable apparatus,dogs in the high social group spent more time looking at people than dogs in the low social group and less time manipulating the apparatus than dogs in the low subgroup,but no statistically significant differences were observed(P＞0.05).Conclusions Highly sociable labradors have a greater cognitive ability,they are more able to suppress impulses during tests,more able to complete the multistep problem solving task,and more inclined to change strategies to seek new cues from people rather than obsessing over manipulating the apparatus when they are unable to solve a problem.

Objective:To explore the differences of gene expression profiles of precursors of exhausted T cells (Tpex) and terminal exhausted T cells (Tex) in the peripheral blood of patients with active pulmonary tuberculosis (ATB).Methods:Twenty-five cases of ATB, 13 cases of latent tuberculosis infection (LTBI) and 10 health controls were enrolled from January 2021 to October 2022 in the Fifth People′s Hospital of Wuxi. The proportions of Tpex and Tex in the peripheral blood mononuclear cells (PBMCs) of the three groups were detected by flowcytometry. PBMCs of ATB were separated into Tpex and Tex by fluorescence-activated cell sorting. RNA-sequencing was performed and up-regulated and down-regulated genes were screended. Differently expressed genes were analyzed by gene set enrichment analysis of gene ontology (GO) to find regulatory pathways affecting cell metabolism and function. Wilcoxon matched-pairs signed rank test, Kruskal-Wallis test and Dunn multiple comparsion test were used for statistical analysis.Results:The proportion of Tpex in ATB group was 2.86%(1.74%), which was lower than 7.93%(6.16%) of Tex, and the difference was statistically significant ( Z=-3.91, P<0.001). The proportions of Tpex and Tex in LTBI group were 9.47%(6.26%) and 7.43%(5.48%), respectively, and the difference was not statistically significant ( Z=-0.93, P=0.345). The proportions of Tpex and Tex in healthy control group were 8.42%(2.69%) and 6.49%(5.14%), respectively, with no statistical significance ( Z=-1.36, P=0.170). There was statistical difference of the proportion of Tpex among the three groups ( H=21.93, P<0.001), and the proportion of Tpex in ATB group was lower than those in LTBI and heathy control groups, and the differences were both statistically significant ( Z=4.16, P<0.001 and Z=3.34, P=0.003, respectively), while the proportions of Tex in these three groups were not statistically different ( H=2.17, P=0.338). Compared with Tex, the gene expressions of memory markers, such as B-cell lymphoma 2 of Tpex were up-regulated, and the gene expressions of exhausted markers, such as lymphocyte activation gene 3 were down-regulated. In terms of cellular metabolism, the gene expressions of mitochondrial protein complex, mitochondrial matrix and oxidative phosphorylation of Tpex were up-regulated, and the gene expressions of glycolysis were down-regulated. The gene expressions of pyruvate metabolism in Tex were up-regulated, and the gene expressions of CD4 + T lymphocyte activation and differentiation and glycolytic process in Tpex were down-regulated. Conclusions:Tpex in ATB express more characteristics of memory cells and less features of exhausted markers compared with Tex, and the function of mitochondria of Tpex preserves well.
