OBJECTIVE To evaluate the influence of pharmaceutical quality control on the efficiency and outcomes of standardized medication therapy management （MTM） services for patients with coronary heart disease by using Economic， Clinical and Humanistic Outcomes （ECHO） model. METHODS This study collected case data of coronary heart disease patients who received MTM services during January-March 2023 （pre-quality control implementation group， n＝96） and June-August 2023 （post-quality control implementation group， n＝164）. Using propensity score matching analysis， 80 patients were selected from each group. The study subsequently compared the economic， clinical， and humanistic outcome indicators of pharmaceutical services between the two matched groups. RESULTS There were no statistically significant differences in baseline data between the two groups after matching （P＞0.05）. Compared with pre-quality control implementation group， the daily treatment cost （16.26 yuan vs. 24.40 yuan， P＜0.001）， cost-effectiveness ratio [23.12 yuan/quality-adjusted life year （QALY） vs. 32.32 yuan/QALY， P＜0.001]， and the incidence of general adverse drug reactions （2.50% vs. 10.00%， P＝0.049） of post-quality control implementation group were decreased significantly； the utility value of the EuroQol Five-Dimensional Questionnaire （0.74± 0.06 vs. 0.71±0.07， P＝0.003）， the reduction in the number of medication related problems （1.0 vs. 0.5， P＜0.001）， the medication adherence score （[ 6.32±0.48） points vs. （6.10±0.37） points， P＝0.001]， and the satisfaction score （[ 92.56±1.52） points vs. （91.95±1.56） points， P＝0.013] all showed significant improvements. Neither group experienced serious adverse drug reactions. There was no statistically significant difference in the incidence of new adverse reactions between the two groups （1.25% vs. 3.75%， P＝0.310）. CONCLUSIONS Pharmaceutical quality control can improve the quality of pharmaceutical care， and the ECHO model can quantitatively evaluate the effect of MTM services， making pharmaceutical care better priced and more adaptable to social needs， thus being worthy of promotion.

OBJECTIVE: To investigate the predictive value of oxygenation index (PaO₂/FiO₂) at intensive care unit (ICU) admission on 30-day mortality in patients with sepsis. METHODS: A retrospective study was conducted. Patients with sepsis who were hospitalized in the ICU of the Affiliated Hospital of Jining Medical University from April 2015 to October 2023 were enrolled. The demographic information, comorbidities, sites of infection, vital signs and laboratory test indicators at the time of admission to the ICU, disease severity scores within 24 hours of admission to the ICU, treatment process and prognostic indicators were collected. According to the PaO₂/FiO₂ at ICU admission, patients were divided into Q1 group (PaO₂/FiO₂ of 4.1-16.4 cmHg, 1 cmHg ≈ 1.33 kPa), Q2 group (PaO₂/FiO₂ of 16.5-22.6 cmHg), Q3 group (PaO₂/FiO₂ of 22.7-32.9 cmHg), and Q4 group (PaO₂/FiO₂ of 33.0-94.8 cmHg). Differences in the indicators across the four groups were compared. Multifactorial Cox regression analysis was used to assess the relationship between PaO₂/FiO₂ and 30-day mortality of patients with sepsis. The predictive value of PaO₂/FiO₂, sequential organ failure assessment (SOFA) and acute physiology and chronic health evaluation II (APACHE II) on 30-day prognosis of patients with sepsis was analyzed by receiver operator characteristic curve (ROC curve). RESULTS: A total of 1 711 patients with sepsis were enrolled, including 428 patients in Q1 group, 424 patients in Q2 group, 425 patients in Q3 group, and 434 patients in Q4 group. 622 patients died at 30-day, the overall 30-day mortality was 36.35%. There were statistically significant differences in age, body mass index (BMI), history of smoking, history of alcohol consumption, admission heart rate, respiratory rate, APACHE II score, SOFA score, Glasgow coma score (GCS), site of infection, Combined chronic obstructive pulmonary disease (COPD), blood lactic acid (Lac), prothrombin time (PT), albumin (Alb), total bilirubin (TBil), pH, proportion of mechanical ventilation, duration of mechanical ventilation, proportion of vasoactive medication used, and maximal concentration, length of ICU stay, hospital stay, incidence of acute kidney injury, in-hospital mortality, 30-day mortality among the four groups. Multivariate Cox regression analysis showed that after adjusting for confounding factors, for every 1 cmHg increase in PaO₂/FiO₂ at ICU admission, the 30-day mortality risk decreased by 2% [hazard ratio (HR) = 0.98, 95% confidence interval (95%CI) was 0.98-0.99, P < 0.001]. The 30-day mortality risk in the Q4 group was reduced compared with the Q1 group by 41% (HR = 0.59, 95%CI was 0.46-0.76, P < 0.001). The fitted curve showed that a curvilinear relationship between PaO₂/FiO₂ and 30-day mortality after adjustment for confounders. In the inflection point analysis, for every 1 cmHg increase in PaO₂/FiO₂ at PaO₂/FiO₂ < 28.55 cmHg, the risk of 30-day death in sepsis patients was reduced by 5% (HR = 0.95, 95%CI was 0.94-0.97, P < 0.001); when PaO₂/FiO₂ ≥ 28.55 cmHg, there was no statistically significant association between PaO2/FiO2 and the increase in the risk of 30-day death in sepsis (HR = 1.01, 95%CI was 0.99-1.02, P = 0.512). ROC curve analysis showed that the area under the curve (AUC) for the prediction of 30-day mortality by admission PaO₂/FiO₂ in ICU sepsis patients was 0.650, which was lower than the predictive ability of the SOFA score (AUC = 0.698) and APACHE II score (AUC = 0.723). CONCLUSION In patients with sepsis, PaO₂/FiO₂ at ICU admission is strongly associated with 30-day mortality risk, alerting healthcare professionals to pay attention to patients with low PaO₂/FiO₂ for timely interventions.

Objective:To investigate the correlation between liver stiffness and histopathological changes in a rat model of acute hepatitis using virtual touch tissue imaging quantification (VTIQ) technology.Methods:A total of 100 SPF-grade SD rats were randomly divided into 3 groups: control ( n=30), low-dose ( n=35), and high-dose ( n=35) groups. Acute hepatitis models were induced in the low-dose and high-dose groups using 400 mg/kg and 600 mg/kg of Thioacetamide (TAA), respectively. Liver stiffness parameters of the right median lobe and right lobe were measured using VTIQ technology, Mean-H and Mean-L represent the liver lobes with higher and lower liver stiffness measurments, respectively, while Mean represent the average of the measurements from both liver lobes. Comparative analyses of liver stiffness parameters were performed across three groups and between the two lobes of the liver. The correlations between the Mean values of liver stiffness and semi-quantitative histopathological data were investigated. Ten rats were randomly selected from each of the 3 groups to test the repeatability of VTIQ values before and after euthanasia with intraperitoneal anesthesia. Subsequently, 10 rats after euthanasia from each 3 group were randomly chosen to assess the repeatability of VTIQ measurements for inter-observer and intra-observer variabilities. Results:VTIQ results showed statistically significant differences in Mean, Mean-H, and Mean-L among the 3 groups (all P<0.01). The high-dose group had higher measurements compared to the low-dose and control groups, with significant intergroup differences (all P<0.01). Significant differences in Mean-H and Mean-L were observed between the two liver lobes in both low and high-dose groups (all P<0.01). The Mean value showed significant positive correlations with semi-quantitative histopathological data of hepatocellular edema, periportal inflammatory cell infiltration, macrophage proliferation, and bile duct proliferation ( r=0.391, 0.648, 0.577, 0.542; all P<0.01). Multivariate linear regression analysis indicated that hepatocellular edema, eosinophilic change, and bile duct proliferation significantly and positively predicted the Mean value (β=-0.278, -0.196, -0.333; all P<0.05). There were no significant differences of VTIQ measurements befor and after euthanasia (all P>0.05), with repeatability coefficients of 0.166, 0.182, 0.185 for Mean, Mean-H, and Mean-L, respectively. Post-euthanasia, inter- and intra-observer VTIQ differences remained non-significant (all P>0.05), with Mean, Mean-H, Mean-L coefficients of 0.114, 0.194, 0.165 and 0.206, 0.322, 0.268, respectively. Conclusions:VTIQ technology demonstrates potential clinical value in assessing a rat model of acute hepatitis, offering a new perspective for non-invasive evaluation of acute hepatitis. However, its clinical application requires further validation.

Objective To explore the changes and influencing factors of recurrence fear level in nasopharyngeal carcinoma radiotherapy patients,and to provide a basis for developing targeted nursing interventions.Methods A prospective study was conducted from January 2022 to June 2023,using a general information questionnaire,the simplified fear of disease progression scale for cancer patients(FoP-Q-SF),the Chinese version of the fatigue scale(CFS),and the M D.Anderson symptom assessment scale(head and neck)(MDASI-H&N)at 1 day before radiotherapy,the 15th dose of radiotherapy,the end of radiotherapy,and 3 months after radiotherapy,Compare the differences in the results of four measurements and analyze their influencing factors.A total of 105 patients completed 4 evaluations,and at the 4 evaluation time points,the fear of cancer recurrence(FCR)scores of nasopharyngeal carcinoma radiotherapy patients were(34.71±7.18)points,(36.18±8.70)points,(26.95±6.29)points,and(25.21±5.90)points,respectively.The results of the generalized estimation equation analysis showed that gender,educational level,economic income,disease stage,fatigue level,and symptom distress were the factors affecting the level of recurrence fear in nasopharyngeal carcinoma radiotherapy patients(P＜0.05).Conclusion Nasopharyngeal cancer radiotherapy patients generally have a fear of recurrence,and the level of fear of recurrence shows dynamic changes.Clinical medical staff should timely evaluate the dynamic changes of fear of recurrence in patients,develop targeted intervention measures from different gender,education level,economic situation,disease stage,and other comprehensive aspects,implement precise and personalized dynamic management,in order to reduce the level of fear of recurrence in patients and improve their quality of life.

Transcriptome analysis based on high-throughput sequencing of a cDNA library has been widely applied to functional genomic studies. However, the cDNA dependence of most RNA sequencing techniques constrains their ability to detect base modifications on RNA, which is an important element for the post-transcriptional regulation of gene expression. To comprehensively profile the N⁶-methyladenosine (m⁶A) and N⁵-methylcytosine (m⁵C) modifications on RNA, direct RNA sequencing (DRS) using the latest Oxford Nanopore Technology was applied to analyze the transcriptome of six tissues in rice. Approximately 94 million reads were generated, with an average length ranging from 619 nt to 1013 nt, and a total of 45,707 transcripts across 34,763 genes were detected. Expression profiles of transcripts at the isoform level were quantified among tissues. Transcriptome-wide mapping of m⁶A and m⁵C demonstrated that both modifications exhibited tissue-specific characteristics. The transcripts with m⁶A modifications tended to be modified by m⁵C, and the transcripts with modifications presented higher expression levels along with shorter poly(A) tails than transcripts without modifications, suggesting the complexity of gene expression regulation. Gene Ontology analysis demonstrated that m⁶A- and m⁵C-modified transcripts were involved in central metabolic pathways related to the life cycle, with modifications on the target genes selected in a tissue-specific manner. Furthermore, most modified sites were located within quantitative trait loci that control important agronomic traits, highlighting the value of cloning functional loci. The results provide new insights into the expression regulation complexity and data resource of the transcriptome and epitranscriptome, improving our understanding of the rice genome.

Objective:To investigate the effects and significance of acute and chronic trauma on brain degree centrality (DC) in patients with post-traumatic stress disorder (PTSD) who lost their only child at resting state.Methods:Retrospectively, the study enrolled a total of 51 parents with PTSD, including 35 PTSD parents whose children was lost in emergencies (acute bereaved PTSD group) and 16 PTSD parents whose children was lost of chronic causes such as diseases (chronic bereaved PTSD group). Fifty local adults were also included as healthy controls (HC group). The clinical administered PTSD scale(CAPS) was used to evaluate the severity of the subjects' clinical symptoms.Resting-state functional magnetic resonance imaging(fMRI) data of all subjects were collected and DC values were calculated.SPSS 22.0 software was used for statistical analysis.Covariance analysis was performed among three groups, while post hoc was performed between any two groups.What's more, correlation analyses were utilized between abnormal brain regions and the scores of CAPS.Results:Significant group effects were found in multiple regions, including the right inferior temporal gyrus (MNI: x, y, z=66, -27, -21), right temporal pole (MNI: x, y, z=54, 15, -9), right orbital inferior frontal gyrus (MNI: x, y, z=42, 21, -15), bilateral medial superior frontal gyri (MNI: right x, y, z=6, 63, 12; left x, y, z=-3, 60, 18), left inferior parietal angular gyrus (MNI: x, y, z=-45, -36, 51) and left postcentral gyrus (MNI: x, y, z=-45, -33, 51). Compared with HC group, the DC of two patient groups increased in the right inferior temporal gyrus (MNI: acute x, y, z=63, -27, -21; chronic x, y, z=63, -21, -27); the DC of acute bereaved PTSD group decreased in the right temporal pole (MNI: x, y, z=45, 21, -15) and the right orbital inferior frontal gyrus (MNI: x, y, z=48, 24, -12), while the DC of chronic bereaved PTSD group decreased in the left inferior parietal angular gyrus (MNI: x, y, z=-45, -36, 51) and left postcentral gyrus (MNI: x, y, z=-45, -33, 51). Compared with chronic bereaved PTSD group, the DC of acute bereaved PTSD group increased in the left inferior parietal angular gyrus (MNI: x, y, z=-33, -39, 42) and left postcentral gyrus (MNI: x, y, z=-45, -33, 51), while decreased in the right temporal pole (MNI: x, y, z=51, 12, -9), right orbital inferior frontal gyrus (MNI: x, y, z=42, 21, -15) and bilateral medial superior frontal gyri (MNI: left x, y, z=0, 57, 15; right x, y, z=3, 57, 15). In chronic bereaved PTSD group, the DC of the left postcentral gyrus was negatively correlated with C1 (avoid trauma-related thoughts, feelings) score in CAPS ( r=-0.606, P=0.028). In acute bereaved PTSD group, the DC of the left medial superior frontal gyrus was negatively correlated with D4 (high vigilance) score ( r=-0.416, P=0.020). Conclusion:There exist functional abnormalities of multiple brain regions in acute and chronic bereaved parents with PTSD.The high arousal symptoms of the former may be related with the abnormalities of prefrontal-amygdala neural circuit, while the latter show higher avoidance which may be associated with the dysfunction of somatosensory brain regions such as postcentral gyrus.

Objective:To investigate the effect of coping style on the gray matter volume in patients with post-traumatic stress disorder (PTSD) who lost their only child, and the mediating role of gray matter volume in evaluating the influence of coping style in clinical symptoms of these parents.Methods:A total of 57 parents with PTSD (PTSD group) and 162 parents without PTSD (non-PTSD group) who lost their only child from September 2016 to March 2017 were enrolled from Jiangsu Province, China. Brain MRI data at resting state were collected. Voxel-based multiple regression analysis was performed to confirm the brain areas in which coping style main effect, diagnosis main effect and their interaction had significant influences in gray matter volumes. Correlations among gray matter volume of brain areas related to coping style, coping style scale scores, and clinician-administered PTSD scale (CAPS) scores were analyzed. Structural equation modeling was used to analyze the mediating role of gray matter volume in the influence of coping style in clinical symptoms of parents lost their only child.Results:(1) The coping style main effect did not significantly influence the gray matter volume in all subjects, and the diagnosis main effect had significant influence in gray matter volume in the right lingual gyrus; their interaction had significant influence in gray matter volume in the right peritalar fissure cortex and lingual gyrus. The positive coping style in the PTSD group had significant influence in the gray matter volumes of the right peritalar fissure cortex and lingual gyrus. (2) In the PTSD group, the scores of positive coping style were positively correlated with the gray matter volumes of the right talus fissure and the lingual gyrus ( P<0.05); the scores of positive coping style, and the gray matter volumes of the right talus fissure and the lingual gyrus were negatively correlated with scores of CAPS-C 5 and CAPS-C ( P<0.05). (3) In the PTSD group, positive coping style can positively predict the gray matter volumes of the right talus fissure and the lingual gyrus; the gray matter volumes of the right talus fissure and the lingual gyrus can negatively predict the avoidance-related symptoms. Conclusion:Positive coping style has influence in the gray matter volumes of the right talar fissure and lingual gyrus of PTSD patients lost their only child; and less positive coping style may affect the brain areas related to visual information processing, thus aggravating avoidance-related symptoms of PTSD patients.

The widespread application of next generation sequencing (NGS) in clinical settings has enabled testing, diagnosis, treatment and prevention of genetic diseases. However, many issues have arisen in the meanwhile. One of the most pressing issues is the lack of standards for reporting genetic test results across different service providers. The First Forum on Standards and Specifications for Clinical Genetic Testing was held to address the issue in Shenzhen, China, on October 28, 2017. Participants, including geneticists, clinicians, and representatives of genetic testing service providers, discussed problems of clinical genetic testing services across in China and shared opinions on principles, challenges, and standards for reporting clinical genetic test results. Here we summarize expert opinions presented at the seminar and report the consensus, which will serve as a basis for the development of standards and guidelines for reporting of clinical genetic testing results, in order to promote the standardization and regulation of genetic testing services in China.
