ObjectiveTo explore the data standard system of electronic medical records in the field of rehabilitation, focusing on the terminology and coding standards, data structure, and key content categories of rehabilitation electronic medical records. MethodsBased on the Administrative Norms for the Application of Electronic Medical Records issued by the National Health Commission of China, the electronic medical record standard architecture issued by the International Organization for Standardization and Health Level Seven (HL7), the framework of the World Health Organization Family of International Classifications (WHO-FICs), Basic Architecture and Data Standards of Electronic Medical Records, Basic Data Set of Electronic Medical Records, and Specifications for Sharing Documents of Electronic Medical Records, the study constructed and organized the data structure, content, and data standards of rehabilitation electronic medical records. ResultsThe data structure of rehabilitation electronic medical records should strictly follow the structure of electronic medical records, including four levels (clinical document, document section, data set and data element) and four major content areas (basic information, diagnostic information, intervention information and cost information). Rehabilitation electronic medical records further integrated information related to rehabilitation needs and characteristics, emphasizing rehabilitation treatment, into clinical information. By fully applying the WHO-FICs reference classifications, rehabilitation electronic medical records could establish a standardized framework, diagnostic criteria, functional description tools, coding tools and terminology index tools for the coding, indexing, functional description, and analysis and interpretation of diseases and health problems. The study elaborated on the data structure and content categories of rehabilitation electronic medical records in four major categories, refined the granularity of reporting rehabilitation content in electronic medical records, and provided detailed data reporting guidance for rehabilitation electronic medical records. ConclusionThe standardization of rehabilitation electronic medical records is significant for improving the quality of rehabilitation medical services and promoting the rehabilitation process of patients. The development of rehabilitation electronic medical records must be based on the national and international standards. Under the general electronic medical records data structure and standards, a rehabilitation electronic medical records data system should be constructed which incorporates core data such as disease diagnosis, functional description and assessment, and rehabilitation interventions. The standardized rehabilitation electronic medical records scheme constructed in this study can support the improvement of standardization of rehabilitation electronic medical records data information.

Objective To study the spatial distribution of the incidence of pulmonary tuberculosis in Hubei Province and its influencing factors, so as to improve the theoretical basis for scientific development of tuberculosis prevention and control measures in the future. Methods The data of reported incidence of tuberculosis and related influencing factors in various counties and districts of Hubei Province in 2020 were collected. Global Moran's I index, hotspot analysis and geographically weighted regression (GWR) model analysis were used to calculate the spatial autocorrelation of the incidence of tuberculosis, and to analyze the influencing factors affecting the incidence rate of tuberculosis. Results There were obvious regional differences in the space distribution of the incidence rate of tuberculosis. Hot spot analysis showed positive spatial correlation and obvious clustering. The GWR model (AICc=784.251) in this study had higher AICc value compared to the ordinary least squares regression (OLS) model (AICc=804.2585). The GWR model showed that the increase in the proportion of the population aged 65 and above and the proportion of the ethnic minority population had a significant promoting effect on the increase of the incidence rate of tuberculosis, and there was significant spatial heterogeneity. The effect of PM_2.5 concentration on the incidence rate of pulmonary tuberculosis varied in different regions, and the degree of effect was also different. Conclusion The proportion of people aged 65 and above and the proportion of ethnic minorities may significantly influence the incidence of pulmonary tuberculosis. The effect of PM_2.5 concentration varies in different regions, so targeted measures should be formulated according to the situation in different regions.

This study aims to investigate the effect of salvianolic acid B (Sal B), the active ingredient of Salvia miltiorrhiza, on H9C2 cardiomyocytes injured by oxygen and glucose deprivation/reperfusion (OGD/R) through regulating mitochondrial fission and fusion. The process of myocardial ischemia-reperfusion injury was simulated by establishing OGD/R model. The cell proliferation and cytotoxicity detection kit (cell counting kit-8, CCK-8) was used to detect cell viability; the kit method was used to detect intracellular reactive oxygen species (ROS), total glutathione (t-GSH), nitric oxide (NO) content, protein expression levels of mitochondrial fission and fusion, apoptosis-related detection by Western blot. Mitochondrial permeability transition pore (MPTP) detection kit and Hoechst 33342 fluorescence was used to observe the opening level of MPTP, and molecular docking technology was used to determine the molecular target of Sal B. The results showed that relative to control group, OGD/R injury reduced cell viability, increased the content of ROS, decreased the content of t-GSH and NO. Furthermore, OGD/R injury increased the protein expression levels of dynamin-related protein 1 (Drp1), mitofusions 2 (Mfn2), Bcl-2 associated X protein (Bax) and cysteinyl aspartate specific proteinase 3 (caspase 3), and decreased the protein expression levels of Mfn1, increased MPTP opening level. Compared with the OGD/R group, it was observed that Sal B had a protective effect at concentrations ranging from 6.25 to 100 μmol·L^-1. Sal B decreased the content of ROS, increased the content of t-GSH and NO, and Western blot showed that Sal B decreased the protein expression levels of Drp1, Mfn2, Bax and caspase 3, increased the protein expression level of Mfn1, and decreased the opening level of MPTP. In summary, Sal B may inhibit the opening of MPTP, reduce cell apoptosis and reduce OGD/R damage in H9C2 cells by regulating the balance of oxidation and anti-oxidation, mitochondrial fission and fusion, thereby providing a scientific basis for the use of Sal B in the treatment of myocardial ischemia reperfusion injury.

Objective:To investigate the value of radiomics nomogram based on standardized pre-treatment chest enhanced CT in predicting the mutation status of epidermal growth factor receptor (EGFR) for patients with lung adenocarcinoma.Methods:A retrospective analysis was conducted on pre-treatment chest enhanced CT images and clinical data of 262 patients from the affiliated hospital of Jining Medical University with pathologically proven primary lung adenocarcinoma who received EGFR gene testing, including EGFR wild type ( n=122) and mutant type ( n=140). The patients were divided into training group ( n=183) and testing group ( n=79) according to a ratio of 7∶3 by stratified sampling method. Standardized pre-processed the images, delineated the ROI and extracted the radiomics features. Least absolute shrinkage and selection operator (LASSO) algorithm was used to reduce the dimension and select key features. The standardized radiomics model, clinical model and the combined model were established by Logistic Regression (LR) machine learning method. Calculated the Rad-score and drew the nomogram. ROC curve and Delong were used to evaluate and compare the predictive performance of different models. Results:23 standardized enhanced CT radiomics features and 4 clinical features were selected. The predictive performance of standardized radiomics model was better than that of non-standardized radiomics model [area under curve (AUC): 0.863 vs. 0.805, t=2.19, P<0.05]. The AUCs of the combined model and standardized radiomics model were higher than that of the clinical model (training group: 0.885, 0.863 vs. 0.774, t=3.57, 2.17, P<0.05; testing group: 0.873, 0.829 vs. 0.763, t=2.19, 2.02, P<0.05). The radiomics nomogram was built based on Rad-score, age, sex, smoking history and BMI. Conclusions:The combined model and standardized radiomics model could effectively predict the mutation status of EGFR gene in lung adenocarcinoma patients before treatment, providing valuable clinical insights.

Objective To investigate the effect of Kangxian Yiai Prescription(KXYA)on the mTOR/HIF-1α/VEGF signaling pathway in a rat model of precancerous lesions of liver cancer.Methods A total of 40 male Wistar rats were divided into normal group,model group,KXYA group,and Biejia Rangan Tablets(BJRG)group,with 10 rats in each group.The rats in the normal group were given intraperitoneal injection of normal saline at a dose of 0.4 mL/100 g,and those in the other three groups were given intraperitoneal injection of diethylnitrosamine at a dose of 50 mg/kg to establish a rat model of the precancerous lesions of liver cancer.Immunohistochemistry and Western Blot were used to measure the expression level of GST-Pi,and quantitative real-time PCR and Western Blot were used to measure the mRNA and protein expression levels of mTOR,HIF-1α,VEGF,PKM2,and GLUT1.A one-way analysis of variance or the Kruskal-Wallis H test was used for comparison of continuous data between multiple groups,and the least significant difference t-test was used for further comparison between two groups.Results Compared with the normal group,the model group had a significant increase in the protein expression level of GST-Pi in liver tissue(P＜0.01),and compared with the model group,the KXYA group had a significant reduction in the protein expression level of GST-Pi(P＜0.05).Compared with the normal group,the model group had significant increases in the mRNA expression levels of GLUT1 and PKM2 in liver tissue(P＜0.01),and compared with the model group,the BJRG group and the KXYA group had a significant reduction in the mRNA expression level of GLUT1(P＜0.05).Compared with the normal group,the model group had significant increases in the protein expression levels of GLUT1 and PKM2 in liver tissue(P＜0.01).Compared with the normal group,the model group had significant increases in the mRNA expression levels of mTOR,HIF-1α,and VEGF in liver tissue(P＜0.01);compared with the model group,the BJRG group had significant reductions in the mRNA expression levels of mTOR and VEGF(P＜0.05),and the KXYA group also had significant reductions in the mRNA expression levels of mTOR and VEGF(P＜0.01).Compared with the normal group,the model group had significant increases in the protein expression levels of mTOR,HIF-1α,and VEGF in liver tissue(P＜0.01);compared with the model group,the BJRG group had a significant reduction in the protein expression level of mTOR(P＜0.01),and the KXYA group had significant reductions in the protein expression levels of mTOR,HIF-1α,and VEGF(P＜0.05);compared with the BJRG group,the KXYA group had a significantly higher protein expression level of mTOR(P＜0.01).Conclusion KXYA can inhibit the precancerous lesions of liver cancer by regulating the mTOR/HIF-1α/VEGF signaling pathway.

Background::Early detection of esophageal squamous cell carcinoma (ESCC) can considerably improve the prognosis of patients. Aberrant cell-free DNA (cfDNA) methylation signatures are a promising tool for detecting ESCC. However, available markers based on cell-free DNA methylation are still inadequate. This study aimed to identify ESCC-specific cfDNA methylation markers and evaluate the diagnostic performance in the early detection of ESCC.Methods::We performed whole-genome bisulfite sequencing (WGBS) for 24 ESCC tissues and their normal adjacent tissues. Based on the WGBS data, we identified 21,469,837 eligible CpG sites (CpGs). By integrating several methylation datasets, we identified several promising ESCC-specific cell-free DNA methylation markers. Finally, we developed a dual-marker panel based on methylated KCNA3 and OTOP2, and then, we evaluated its performance in our training and validation cohorts. Results::The ESCC diagnostic model constructed based on KCNA3 and OTOP2 had an AUC of 0.91 [95% CI: 0.85–0.95], and an optimal sensitivity and specificity of 84.91% and 94.32%, respectively, in the training cohort. In the independent validation cohort, the AUC was 0.88 [95% CI: 0.83–0.92], along with an optimal sensitivity of 81.5% and specificity of 92.9%. The model sensitivity for stage I–II ESCC was 78.4%, which was slightly lower than the sensitivity of the model (85.7%) for stage III–IV ESCC. Conclusion::The dual-target panel based on cfDNA showed excellent performance for detecting ESCC and might be an alternative strategy for screening ESCC.

Objective:To retrospectively analyze the viral levels and associated factors in patients with hepatitis B virus (HBV)-related primary liver cancer (PHC) in real-world settings and further explore the correlation between low viral load (LVL) and/or low-level viremia (LLV) and PHC.Methods:Five hundred twenty-four cases with HBV-related PHC with complete pathologically confirmed data from 2013 to 2020 were included. Percentages (%) were used to express their viral load, antiviral (oral) status, patient compliance, presence or absence of cirrhosis, family history of liver cancer, and others. LVL definition: After excluding detection errors by PCR method, serum HBV DNA <50-2 000 IU/ml, and those who had received antiviral drug treatment were called LLV. Antiviral treatment (AVT) rate definition: As of the confirmed diagnosis of PHC, those who had been regularly treated using oral antiviral drugs for six months or more (≥6 months).Results:General situation: The ratio of male to female enrolled patients was 15.90:1 (493/31). Patients aged >40 years accounted for 91.98% (482 cases). Hepatitis B surface antigen (HBsAg) positivity condition: The ratio of HBsAg-positive to HBsAg-negative/anti-HBc-positive (HBsAg-/anti-HBc+) PHC patients was 5.89:1 (448/76). Among the 76 HBsAg-/anti-HBc+patients, the ratio of HBsAg-/anti-HBs+/anti-HBc+ to HBsAg-/anti-HBs-/anti-HBc+ patients was 0.95:1 (37/39). Hepatitis B e antigen (HBeA) positivity condition: The ratio of HBeAg-negative to HBeAg-positive cases was 3.23:1 (400/124). HBV DNA level condition: The medical history records of 75.00% of patients (393/524) had traceable HBV DNA test reports. Out of 393 patients, 45.04% (177/393) accounted for undetectable HBV DNA, 13.49% (53/393) accounted for LVL, 41.48% (163/393) accounted for HBV DNA exceeding the upper limit of LVL, and 4.07% (16/393) accounted for LLV. Among HBsAg-positive and HBsAg-/anti-HBc+ patients, the HBV DNA positivity rates were 59.12% (214/362) and 6.45% (2/31), respectively. Antiviral treatment condition: Among the 448 HBsAg-positive PHC patients, the total AVT rate was 18.08% (81/448), of which seven patients did not have their HBV DNA results traced back. Among them, the AVT rate of 148 patients with HBV DNA lower than the lowest detection value was 41.22% (61/148); the AVT rate of 53 patients with LVL was 18.87% (10/53); and the AVT rate of 163 patients with HBV DNA≥LVL upper limit was 1.84% (3/163). Liver cirrhosis and family history condition: 348 patients (66.41%) had liver cirrhosis. 67 patients (12.79%) had a distinct family history of HBV-related liver cirrhosis and liver cancer. Alpha-fetoprotein (AFP) condition: 514 patients underwent AFP testing, with 30.93% of the patients had normal AFP levels, and 69.07% had AFP levels exceeding the upper limit of normal values (355/514). Among them, 10 μg/L400 μg/L accounted for 34.44% (177/514) and 34.63% (178/514), respectively. Tissue typing condition: 99.05% (519/524) were hepatocellular carcinoma, and well-differentiated and moderately differentiated cases accounted for only 8.59%.Conclusions:In the real world, comprehensive, timely screening, standardized, and effective antiviral treatment have not yet been achieved for patients with chronic hepatitis B, resulting in the persistence of HBsAg and/or HBV DNA positivity (especially LVL and/or LLV). Although LVL does not account for a high proportion among all HBV-related PHC populations, the vast majority of LVL populations have not received any antiviral treatment. In addition, some PHC populations with HBV DNA>2 000 IU/ml have not received standard antiviral treatment before the onset of the disease, which should be paid attention to. At the same time, HBsAg-/anti-HBc+ populations may have latent HBV infection and may even progress to PHC. Notably, PHC may still occur after HBeAg seronegative conversion.

Differentiation of oligodendrocyte precursor cells(OPCs)into mature oligodendrocytes(OLs)is a key event for axonal myelination in the central nervous system(CNS).Stud-ies have shown that neurotransmitters like GABA,GABAergic synapses and network regulation play important roles in the pro-liferation,differentiation,migration and myelination of oligoden-drocytes.Therefore,the paper reviews recent studies on the bio-logical functions of GABA and its receptors in oligodendrocyte lineages,the interaction between GABAergic interneurons and OPCs,the network regulation of GABAergic interneurons media-ting myelination,and potential future drug candidates.Based on this,understanding the mechanisms that control OLs differentia-tion is essential for identifying therapeutic strategies that promote myelin repair,and research surrounding GABAergic may have potential implications for the development of novel repair thera-pies for demyelinating diseases.
