Objective: To explore the correlation among picky eating levels in preschool children, parental self-efficacy and parenting stress. Methods: A convenience sampling method was employed to conduct an electronic questionnaire survey among 459 children aged 3-6 years and their parents from five kindergartens in Urumqi in November 2023. The survey included a general information questionnaire, the Children s Eating Behavior Questionnaire (CEBQ), the Parenting Sense of Competence Scale (PSOC), and the Parenting Stress Index-Short Form (PSI-SF). The Mann-Whitney U-test was used for twogroup comparisons, and the Kruskal-Wallis H-test was applied for multi-group comparisons. Spearman correlation analysis was conducted to examine the relationships between children s picky eating levels and parenting selfefficacy as well as parenting stress. Results: The picky eating score of preschool children was 10.00 (4.00), and the parenting self-efficacy score was 58.00 (12.00), both indicating a moderate level. The parenting stress score was 75.00 (16.00), reflecting a moderately low level. Spearman correlation analysis showed that children s picky eating levels were negatively correlated with the total score of parenting self-efficacy ( r =-0.28) and positively correlated with the total score of parenting stress( r =0.25)( P <0.01). Conclusions Picky eating levels of preschool children are closely associated with parenting self-efficacy and parenting stress. Picky eating behaviors in children can be reduced by implementing various effective measures to enhance parenting self-efficacy and alleviate parenting stress.

Objective: To investigate the risk factors affecting the early diagnosis of ABO-hemolytic disease of the fetus and newborn (ABO-HDFN) in neonates with maternal-fetal blood group incompatibility, and to develop a risk prediction model and validate its predictive performance, so as to provide a reference for the early diagnosis of neonates with ABO-HDFN in primary hospitals. Methods: A total of 1 229 neonates with maternal-fetal blood group incompatibility suspected of ABO-HDFN, admitted to our hospital between between June 2021 and September 2024, were enrolled. The sample size was calculated by using the events per variable (EPV) method. The cohort was divided into a modeling group (n=860) and a validation group (n=369), and the results and clinical information of laboratory examination indicators were collected. Univariate and multivariate logistic regression analysis were used to explore the risk factors affecting the early diagnosis of ABO-HDFN in neonates with maternal-fetal blood group incompatibility. The risk prediction model was developed and internally validated by the Bootstrap method. The goodness-of-fit of the model was evaluated by the Hosmer-Lemeshow (H-L) test, and the receiver operating characteristic (ROC) curve was used to analyze the predictive performance of the model. The prediction model was validated by using the validation group data, and the predictive performance of the model was evaluated. Results: Among the 860 neonates with maternal-fetal incompatibility in the modeling group, 346 (346/860, 40.23%) were diagnosed with ABO-HDFN. Univariate and multivariate logistic regression analyses identified the following as significant risk factors for early diagnosis: the number of postnatal days at specimen collection, maternal type O blood group, parity >1, time of onset for pathologic jaundice, maternal-fetal blood group incompatibility due to A antigen, the level of total bilirubin, and the immature reticulocyte fraction (IRF). A risk prediction model was established, and the calibration degree of the model was validated by the Bootstrap internal validation method, Brier=0.143. The results of H-L test showed that χ =3.464, P=0.902. The area under the ROC curve (AUC) was 0.885. The maximum value of the Youden index was 0.611, the sensitivity was 0.832, and the specificity was 0.778. The results of the validation group showed that the area under the ROC curve was 0.863, with a sensitivity of 0.875 and specificity of 0.735. Conclusion: The risk prediction model developed based on these risk factors has good predictive performance for ABO-HDFN, facilitating early diagnosis of suspected ABO-HDFN cases by clinicians in primary hospitals.

Objective:To analyze the three-dimensional radiographic characteristics of calcifying odon-togenic cyst and calcifying epithelial odontogenic tumor using spiral computed tomography(CT)and cone-beam computed tomography(CBCT).Methods:Clinical records,histopathological reports,and CBCT or non-enhanced spiral CT images of 19 consecutive patients with calcifying odontogenic cyst(COC)and 16 consecutive patients with calcifying epithelial odontogenic tumor(CEOT)were retrospec-tively acquired,and radiographic features,including location,size,expansion,internal structure and calcification,were analyzed.Results:Among the 19 COC cases(12 males and 7 females,with an average age of 27 years),89.5％(17/19)of the lesions originated from the anterior and premolar areas,100.0％of them exhibited cortex expansion,and 78.9％had discontinued cortex.Among the 16 CEOT cases(3 males and 13 females,with an average age of 36 years),81.3％(13/16)of the lesions were in the premolar and molar areas,56.3％of them exhibited cortex expansion,and 96.8％had discontinued cortex.According to the distribution of internal calcifications,these lesions were divided in-to:Ⅰ(non-calcification type):absence of calcification;Ⅱ(eccentric marginal type):multiple calcifi-cations scattered along one side of the lesion;Ⅲ(diffused type):numerous calcifications diffusely dis-tributed into the lesion;Ⅳ(plaque type):with a ≥ 5 mm calcified patch;V(peri-coronal type):multiple calcifications clustered around impacted teeth.Calcifications were present in 73.7％of COC le-sions,including 9 type Ⅱ,3 type Ⅲ and 2 type Ⅳ lesions,and 42.8％of CEOT lesions had calcifica-tion images,including 2 type Ⅲ and 5 type V lesions.Six COC lesions had odontoma-like images.Moreover,8 of 9 type Ⅰ CEOTs were histologically Langerhans cell-rich subtype,which had a smaller size(with an average mesiodistal diameter of 17.8 mm)and were not associated with impacted teeth.Conclusion:COC lesions tended to originate from the anterior part of the jaw and exhibit cortex expan-sion,and were sometimes associated with odontoma.CEOT commonly occurred in the posterior jaw and had discontinued cortex.Two lesions had significantly different calcification map.Over 70％of COC le-sions had calcification images,which were mostly scattered along one side of the cysts,far from the im-pacted teeth.Approximately 60％of CEOT lesions exhibited smaller size and non-calcification,and the remaining CEOT cases often had calcification images clustered around the impacted teeth.

Objective To determine the acetylation level of nucleophosmin(NPM)in female breast cancer and to discuss its function through mutation of modified lysine sites.To construct positive and negative NPM mutants on its acetylated lysine sites and to express them in breast cancer cells.Methods Acetylation level and acetylated lysine sites of NPM in three breast cancer tissues and para-carcinoma tissues were detected by acetylome technology;NPM mutants were constructed by site-directed mutagenesis PCR,specific PCR products were digested by DpnI and transformed into Escherichia coli(E.coli)to obtain specific plasmids for mutants;The accuracy of mutants were verified by double restriction enzyme digestion and sequencing;The mutants were expressed in BT-549 cells by transient transfection and verified by RT-PCR method.Protein expression and acetylation level of NPM were validated by Western blotting;Function of NPM acetylation was analyzed by proteomic detection and bioinformatic analysis.Results The 27th and 32nd lysine of NPM were highly acetylated in breast cancer tissues,which were 2.76 and 2.22 times higher than those in adjacent normal tissues,respectively;The NPM mutants showed the same molecular weight as that of wild type NPM and contained expected mutation sites;Corresponding NPM mRNA levels of BT-549 cells transfected with NPM mutants were significantly increased.With the increase of wild type NPM expression level,NPM acetylation level increased,while decreased after 27th lysine underwent negative mutation.NPM acetylation can significantly change the expression levels of 101 proteins in BT-549 cells,which are enriched in regulation of cellular macromolecule biosynthesis,DNA-template transcription,RNA biosynthesis and RNA metabolism process.Conclusion NPM is highly acetylated in breast cancer and can play a key role in cellular macromolecule biosynthesis,DNA-templated transcription,RNA biosynthesis and RNA metabolism process.

OBJECTIVE To observe the short-term efficacy and safety of venetoclax combined with homoharringtonine and cytarabine in the treatment of acute myeloid leukemia （AML）. METHODS The data of 40 newly diagnosed AML patients admitted to our hospital from October 2022 to November 2023 were retrospectively collected and divided into observation group and control group according to treatment plan， with 20 cases in each group. The patients in the control group were given Daunorubicin hydrochloride for injection+Cytarabine for injection， and the patients in the observation group were given Venetoclax tablets+ Homoharringtonine injection+Cytarabine for injection. The patients in both groups were given relevant medicine， with 28 days as one cycle. The short-term efficacy， negative rate of minimal residual disease （MRD）， duration of granulocyte deficiency， duration of platelet （PLT） ＜20×109 L－1， transfusion volume of suspended red blood cells and platelet， and the occurrence of adverse drug reactions were evaluated in both groups after 1 cycle of induction chemotherapy. RESULTS The complete remission or complete remission with incomplete hematologic recovery （CR/CRi） rate in the observation group was significantly higher than control group （P＜0.05）， and the negative rate of MRD in the observation group was also significantly higher than control group （P＜0.05）. However， in low-， medium- and high-risk patients， there was no statistical significance in CR/CRi rates between the two groups （P＞0.05）. There were no significant differences in the duration of agranulocytosis， the duration of PLT ＜20×109 L－1， the amount of suspended red blood cell transfusion， the amount of platelet transfusion， the incidence of hematologic toxicity and the incidence of non-hematologic toxicity between 2 groups （P＞0.05）. CONCLUSIONS Venetoclax combined with homoharringtonine and cytarabine show good short-term efficacy and safety in the treatment of AML.

Morita therapy has been bom for more than 100 years.Inpatient Morita therapy is highly oper-able and easy to master.It can improve many refractory neuroses through four-stage treatment.But more neuroses are treated in outpatient clinics,and Morita therapy cannot be used in hospitalized patients.Therefore,the formula-tion of expert opinions on outpatient operations is particularly important.This paper is based on domestic and for-eign references,and after many discussions by domestic Morita therapy experts,and then drew up the first version of the expert opinions on operation of outpatient Morita therapy.Meanwhile the operation rule of Morita therapy in three stages of outpatient treatment was formulated:in the etiological analysis stage,under the theoretical guidance of Morita therapy,analyze the pathogenic factors,to improve treatment compliance and reduce resistance;during the operating stage,guide patients to engage in constructive and meaningful actions,realizing the achievement of letting nature take its course principle;in the cultivating character and enriching life stage,pay attention to positive infor-mation,expanding the scope and content of actions,improving the ability to adapt to complex life,and preventing recurrence caused by insufficient abilities.It will lay a foundation for the promotion of Morita therapy in domestic outpatient clinics,so that more patients with neurosis and other psychological diseases could receive characteristic Morita therapy treatment in outpatient clinics.

Objective:To observe the effects of acupuncture and moxibustion on interleukin(IL)-9/IL-9 receptor(IL-9R)in the colon tissue of rats with ulcerative colitis(UC)and investigate the protective mechanism of acupuncture and moxibustion on the intestinal mucosal barrier in UC rats. Methods:Male Sprague-Dawley rats were randomly divided into a normal control(NC)group and a modeling group.UC models were prepared by giving 4%dextran sulfate sodium(DSS)water for 7 d.After the successful construction of the UC rat model,the modeling group was randomly divided into a UC group,a herb-insulated moxibustion(HM)group,and an electroacupuncture(EA)group.HM and EA interventions at bilateral Tianshu(ST25)were performed once a day for 7 d.Hematoxylin-eosin(HE)staining was used to observe the histopathological changes in the colon.The serum concentrations of IL-9,IL-6,IL-1β,and hemoglobin-H(HbH)were determined by enzyme-linked immunosorbent assay.The protein expression levels of IL-9,IL-9R,claudin-2,zonula occludens-1(ZO-1),and occludin in the colon tissue were measured by Western blotting or immuno-histochemistry.Immunofluorescence was used to detect the co-expression of PU.1 and CD4 with the IL-9 protein. Results:Compared with the NC group,the colon tissue of UC rats was severely damaged and ulcerated with congestion and edema,and the colonic histopathological score increased significantly(P<0.01).The serum HbH concentration decreased significantly(P<0.01),while the serum concentrations of IL-9,IL-6,and IL-1β increased(P<0.01).The protein expression of colonic ZO-1 and occludin decreased significantly(P<0.01),while the protein expression of colonic IL-9 and IL-9R increased(P<0.05).The positive co-expression levels of IL-9/PU.1 and IL-9/CD4 increased in the colon tissue(P<0.05).Compared with the UC group,the colonic mucosal structures were gradually repaired in both HM group and EA group,and healed ulcers could be observed,the colonic histopathological score decreased significantly(P<0.05).The serum concentration of HbH increased(P<0.01),while the serum concentrations of IL-9,IL-6,and IL-1β decreased(P<0.05).The protein expression levels of ZO-1 and occludin increased(P<0.05),while the protein expression levels of IL-9 and IL-9R decreased(P<0.01).The positive co-expression levels of IL-9/PU.1 and IL-9/CD4 decreased in the colon tissue(P<0.05). Conclusion:Both HM and EA can inhibit the protein expression levels of IL-9 and IL-9R in the UC colon by regulating the transcription factor PU.1,promote the repair of intestinal mucosal barrier,and down-regulate protein contents of proinflammatory factors IL-9,IL-6,and IL-1β in the serum,which may be one of the key mechanisms of acupuncture and moxibustion in reducing the inflammation of UC colonic mucosa and protecting the intestinal mucosal barrier.
