ObjectiveTo observe the effect of gene mutation on the effectiveness of arsenic-containing Chinese herbal compound formulas in the treatment of myelodysplastic syndromes （MDS） of different traditional Chinese medicine （TCM） patterns， so as to provide the basis for the clinical application. MethodsClinical data of 442 MDS patients who were treated with arsenic-containing herbal compound formulas were retrospectively collected， including the baseline demographic and clinical characteristics of the patients. Based on the TCM four examinations， the patients were divided into the spleen-kidney deficiency group as well as the qi-yin deficiency group， and according to the results of the next-generation sequencing （NGS） test， they were divided into the group with and without gene mutation respectively. The influence of gene mutation on the clinical effectiveness of patients with different TCM patterns was analyzed， the baseline demographic and clinical characteristics of the patients with different outcomes of the two TCM patterns were compared， and multivariate Logistic regression analysis was conducted on the influencing factors of the effective rate of MDS patients with gene mutation. ResultsA total of 190 cases were included in the spleen-kidney deficiency group （119 cases with gene mutation） and 43 cases in the qi-yin deficiency group （23 cases with gene mutation）. No statistically significant differences were noted in effectiveness assessment， total effective rate， and total response rate between the spleen-kidney deficiency group and the qi-yin deficiency group （P＞0.05）. In the spleen-kidney deficiency group， the total effective rate of MDS with gene mutation was 65.55% （78/119）， which was lower than 80.28% （57/71） of MDS without gene mutation， with statistical significance （P = 0.033）， while no statistical differences in effectiveness assessment and total response rate were noted （P＞0.05）. In the qi-yin deficiency group， no statistical differences were observed in effectiveness assessment， total effective rate， and total response rate of the patients in with or without gene mutation （P＞0.05）. In the spleen-kidney deficiency group with gene mutation， the rate of complex karyotype （P = 0.031） and the mutation rate of CBL gene （P = 0.032） in the ineffective population were higher than those in the effective population， while the mutation rate of DDX41 gene in the effective population was higher than that in the ineffective population （P = 0.033）. No statistically significant differences were found in other gene mutations， age， gender distribution， number of gene mutations， bone marrow hyperplasia degree， blast cell range， reticular fiber tissue proliferation or not， and prognosis of chromosomal abnormalities between the effective and ineffective populations （P＞0.05）. In the qi-yin deficiency group with gene mutation， no statistically significant differences were found in various items between populations with different outcomes （P＞0.05）. Multivariate Logistic regression analysis showed that complex karyotype， CBL mutation， and DDX41 mutation were independently associated with the effective rate of MDS with spleen-kidney deficiency and gene mutation （P＜0.05）. DDX41 mutation was an independent protective factor in the spleen-kidney deficiency group （OR＞1）， while complex karyotype and CBL mutation were independent risk factors （OR＜1）. ConclusionThe arsenic-containing TCM compound formulas exhibited better effectiveness in MDS with spleen-kidney deficiency pattern without mutation； and in MDS with spleen-kidney deficiency pattern without complex karyotypes， CBL mutation， and with DDX41 mutations. Furthermore， DDX41 mutation was an independent protective factor in the spleen-kidney deficiency group， while complex karyotype and CBL mutation were independent risk factors. In MDS with qi-yin deficiency pattern， gene mutation-related factors showed no significant impact on the effectiveness of arsenic-containing TCM compound formulas.

ObjectiveMyelodysplastic syndromes （MDS） is a group of clonal hematopoietic stem cell disorders，and this study aims to investigate the expression of hypoxia-inducible factor-1α（HIF-1α） in the bone marrow cells of patients with MDS and its correlation with the clinical features of MDS，the therapeutic efficacy of arsenic-containing Chineseherbal compound，and the survival prognosis. MethodAccording to the inclusion and exclusion criteria，27 MDS patients treated with arsenic-containing Chinese herbal compound in the Department of Hematology，Xiyuan Hospital，China Academy of Chinese Medical Sciences from January 2022 to September 2022 were included，and their bone marrow samples were collected by myelotomy. HIF-1α expression level in bone marrow cells was detected by real-time polymerase chain reaction （PCR） to analyze its correlation with clinical features，and logistic and Cox regression was used to analyze the risk factors affecting the efficacy and prognostic survival of MDS patients. ResultThe HIF-1α mRNA expression level was lower in bone marrow cells of MDS patients than in healthy subjects. HIF-1α was positively correlated with the degree of myelodysplasia（r=0.384，P<0.05） and bone marrow granulocytic system%（G%）（r=0.560，P<0.01）. Logistic regression showed that HIF-1α was a risk factor for the prognosis in the follow-up of the efficacy of treatment（P<0.05）and Cox regression showed that HIF-1α was an independent factor affecting the survival prognosis of MDS patients ［odds ratio（OR）=398.968，95% confidence interval（CI）（1.281，116 858.743），P<0.05］. ConclusionThe level of HIF-1α expression in bone marrow cells of MDS patients was closely related to the degree of clinical myelodysplasia and G%，and HIF-1α was a risk factor for the efficacy for and survival prognosis of MDS patients.

Objective To explore the correlation between the expression level of serum Receptor for Advanced Glycation End-Product(RAGE)and High-Mobility Group Protein B1(HMGB1)expression with the occurrence of acute respiratory distress syndrome(ARDS)and interferon-γ/interleukin-4(IFN-γ/IL-4)ratio in patients with severe pneumonia(SP).Methods A prospective investigation was carried out on one hundred children with SP admitted to our hospital from March 2020 to February 2022,and the participants were classified into ARDS group(n = 56)and control group(n = 44)based on the occurrence of secondary ARDS.General informations werec-ollected.The expression of RAGE,HMGB1,IFN-γ and IL-4 in peripheral blood was measured using Enzyme-Linked Immunosorbent Assay(ELISA).Then multivariate Logistic regression analysis was conducted to screen the influencing factors of secondary ARDS in SP children,and the correlation with IFN-γ/IL-4 ratio was verified by pearson correla-tion analysis,moreover,receiver operating characteristic(ROC)curve was plotted to evaluate the value of RAGE and HMGB1 expression in predicting the occurrence of ARDS in SP children.Results There were no statistical difference in gender,age,body temperature and onset season between the two SP groups.The ARDS group had more types of pathogenic bacteria,larger ratio of the partial pressure of oxygen in arterial blood to the inspired oxygen fraction(PaO2/FiO2),higher Acute Physiological Score(APS),and up-regulated expression of RAGE,HMGB1,IFN-γ and IL-4,as well as larger IFN-γ/IL-4 ratio than those of control group,with statistical difference(all P<0.05).Multivariate Logistic regression analysis revealed that pathogen type,PaO2/FiO2 ratio,RAGE,HMGB1,IFN-γ,IL-4 and IFN-γ/IL-4 were the influencing factors for the occurrence of ARDS in children with SP.Pearson correlation test denoted that the serum RAGE and HMGB1 expression levels of SP children were positively correlated with IFN-γ,IL-4 and IFN-γ/IL-4 ratio(P<0.05).ROC curve found that the AUC of serum RAGE and HMGB1 in predicting the occurrence of ARDS in SP children was 0.707 and 0.750,with a sensitivity of 73.2%and 64.3%,and a specificity of 68.2%and 77.3%.The combined test of RAGE and HMGB1 in predicting the occurrence of ARDS in SP children reached an AUC of 0.848,providing a sensitivity and specificity of 80.4%and 81.8%respectively.Conclusions Serum RAGE and HMGB1 expression levels are elevated in SP children with ARDS,and the two are positively correlated with IFN-γ/IL-4 ratio.Therefore,monitoring serum RAGE and HMGB1 expression in children with ARDS secondary to SP has predictive value for the risk of ARDS in SP children.

Objective:To evaluate the efficacy and safety of oliceridine for treatment of moderate to severe pain after surgery with general anesthesia in patients.Methods:The patients with moderate to severe pain (numeric pain rating scale ≥4) after abdominal surgery with general anesthesia from 14 hospitals between July 6, 2021 and November 9, 2021 were included in this study. The patients were assigned to either experiment group or control group using a random number table method. Experiment group received oliceridine, while control group received morphine, and both groups were treated with a loading dose plus patient-controlled analgesia and supplemental doses for 24 h. The primary efficacy endpoint was the drug response rate within 24 h after giving the loading dose. Secondary efficacy endpoints included early (within 1 h after giving the loading dose) drug response rates and use of rescue medication. Safety endpoints encompassed the development of respiratory depression and other adverse reactions during treatment.Results:After randomization, both the full analysis set and safety analysis set comprised 180 cases, with 92 in experiment group and 88 in control group. The per-protocol set included 170 cases, with 86 in experiment group and 84 in control group. There were no statistically significant differences between the two groups in 24-h drug response rates, rescue analgesia rates, respiratory depression, and incidence of other adverse reactions ( P>0.05). The analysis of full analysis set showed that the experiment group had a higher drug response rate at 5-30 min after giving the loading dose compared to control group ( P<0.05). The per-protocol set analysis indicated that experiment group had a higher drug response rate at 5-15 min after giving the loading dose than control group ( P<0.05). Conclusions:When used for treatment of moderate to severe pain after surgery with general anesthesia in patients, oliceridine provides comparable analgesic efficacy to morphine, with a faster onset.

Objective To propose a family-centred health education program for family caregivers of Autistic children and investigate its clinical value.Methods Delphi method was used to establish a family-centred Autistic children care program for family caregivers looking after the Autistic children,which involved two rounds of expert consultation.The pre-and post-control method for different cases was employed in the study.Forty Autistic caregivers in our hospital from January 2022 to October 2022 were assigned to the control group and another 40 in our hospital from November 2022 to January 2023 were assigned to the observation group.The family caregivers of Autistic children in the control group received traditional care education,while those in the observation group was managed with the family-centred Autistic children health education program.The two groups were compared in terms of care burden,knowledge of health education,and evaluation of clinical symptom of Autistic children.Results The expert authority coefficient of the first round of expert consultation was 0.875 respectively and those in the second round was 0.900,respectively.The coefficient of variation of the coordination degree of each index was 0.04-0.20.Kendalls W scores of the two rounds were 0.794 and 0.786,respectively.A health education program for family-centred Autistic children caregiver was established to consist of three subjects:caregiver training,family-centred parental care and activation of positive emotions of autistic caregivers.Autism caregivers in both groups had completed the study.In comparison with the control group,the care burden of the observation group was significantly lower,the knowledge of health education was significantly higher,and the evaluation of children's clinical symptoms was better among the family caregivers of autistic children in the observation group(all P<0.05).Conclusions The family-centred autistic children care program for family caregivers is scientific and applicable.It is conducive to providing health education guidance for family caregivers of Autistic children,effectively reducing the care burden and enhancing the knowledge of health education.

ObjectiveTo observe the effect of natural moxibustion at "Feishu （BL 13）" on immune balance of T helper cell 17 （Th17） / regulatory T cell （Treg） in healthy rats. MethodsForty-eight rats were randomly divided into 10 rats in the sham moxibustion group and 38 rats in natural moxibustion group. The rats in the sham moxibustion group applied blank acupoint stickers to bilateral "Feishu （BL 13）"， and the rats in natural moxibustion group applied acupoint stickers filled with Compound Banmao Ointment （复方斑蝥膏） to bilateral "Feishu （BL 13）" for a period of 8 h. Thirty rats in natural moxibustion group were successfully blistered after 8 h， and then were randomly divided into 1-day， 3-day and 7-day groups with 10 rats in each group. The general condition of rats was recorded during the experiment； different time groups of natural moxibustion were sampled at the corresponding time， and HE staining was used to observe the pathological changes of the skin in the area of application； flow cytometry was used to detect the subpopulations of Th17 and Treg in peripheral blood， and the value of Th17/Treg was calculated； and ELISA was used to detect the serum interleukin 17A （IL-17A） and interleukin 6 （IL-6）， interleukin 10 （IL-10） levels. ResultsCompared with sham moxibustion group， blisters can be seen in the application area of rats in 1-day natural moxibustion group， and the rats often scratched the skin of the moxibustion area， which showed loose stratum corneum， thickening of the stratum spinosum and stratum granulosum， absence of cells in the basal layer， inflammatory cell infiltration， and elevation of Treg in peripheral blood， and serum IL-17A， IL-6； in 3-day natural moxibustion group， the moxibustion area of the rats was scabbed and partially detached， with the most obvious dermatopathological changes， and elevated peripheral blood Th17 and Treg， and serum IL-17A， IL-6， IL-10； in 7-day natural moxibustion group， skin damage and pathological changes in the area of moxibustion were basically restored； Th17/Treg values were reduced in 1-， 3- and 7-day moxibustion groups after blistering （P＜0.05 or P＜0.01）. Compared with the 1-day moxibustion group， peripheral blood Th17， Treg， and serum IL-17A elevated in the 3-day moxibustion group； peripheral blood Treg， serum IL-17A， and IL-6 decreased， and Th17/Treg values elevated in the 7-day moxibustion group （P＜0.05 or P＜0.01）. Compared with the 3-day moxibustion group， the 7-day moxibustion group had lower peripheral blood Th17 and Treg， serum IL-17A， IL-6， and IL-10， and higher Th17/Treg values （P＜0.05 or P＜0.01）. ConclusionNatural moxibustion at "Feishu （BL 13）" can shift the Th17/Treg balance towards Treg of healthy rats， which will gradually lead to immune homeostasis， and regulate the relevant inflammatory factors in the serum to prevent inflammation from occurring and developing.

Objective To investigate the feasibility of developing a grading diagnostic model for schistosomiasis-induced liver fibrosis based on B-mode ultrasonographic images and clinical laboratory indicators. Methods Ultrasound images and clinical laboratory testing data were captured from schistosomiasis patients admitted to the Second People’s Hospital of Duchang County, Jiangxi Province from 2018 to 2022. Patients with grade I schistosomiasis-induced liver fibrosis were enrolled in Group 1, and patients with grade II and III schistosomiasis-induced liver fibrosis were enrolled in Group 2. The machine learning binary classification tasks were created based on patients’radiomics and clinical laboratory data from 2018 to 2021 as the training set, and patients’radiomics and clinical laboratory data in 2022 as the validation set. The features of ultrasonographic images were labeled with the ITK-SNAP software, and the features of ultrasonographic images were extracted using the Python 3.7 package and PyRadiomics toolkit. The difference in the features of ultrasonographic images was compared between groups with t test or Mann-Whitney U test, and the key imaging features were selected with the least absolute shrinkage and selection operator (LASSO) regression algorithm. Four machine learning models were created using the Scikit-learn repository, including the support vector machine (SVM), random forest (RF), linear regression (LR) and extreme gradient boosting (XGBoost). The optimal machine learning model was screened with the receiver operating characteristic curve (ROC), and features with the greatest contributions to the differentiation features of ultrasound images in machine learning models with the SHapley Additive exPlanations (SHAP) method. Results The ultrasonographic imaging data and clinical laboratory testing data from 491 schistosomiasis patients from 2019 to 2022 were included in the study, and a total of 851 radiomics features and 54 clinical laboratory indicators were captured. Following statistical tests (t = −5.98 to 4.80, U = 6 550 to 20 994, all P values < 0.05) and screening of key features with LASSO regression, 44 features or indicators were included for the subsequent modeling. The areas under ROC curve (AUCs) were 0.763 and 0.611 for the training and validation sets of the SVM model based on clinical laboratory indicators, 0.951 and 0.892 for the training and validation sets of the SVM model based on radiomics, and 0.960 and 0.913 for the training and validation sets of the multimodal SVM model. The 10 greatest contributing features or indicators in machine learning models included 2 clinical laboratory indicators and 8 radiomics features. Conclusions The multimodal machine learning models created based on ultrasound-based radiomics and clinical laboratory indicators are feasible for intelligent identification of schistosomiasis-induced liver fibrosis, and are effective to improve the classification effect of one-class data models.
