Objective:To investigate the effect of ear acupoint bean pressing on gastrointestinal motility and related hormones after laparoscopic surgery in patients with hysteromyoma,and to explore the therapeutic mechanism of ear acupoint bean pressing.Methods:Patients undergoing laparoscopic myomectomy in the Department of Gynecology of The People's Hospital Affiliated to Fujian Univer-sity of Traditional Chinese Medicine from May 2022 to December 2023 were randomly divided into an experimental group and a control group,with 57 patients in each group.The experimental group was treated with postoperative routine nursing and ear acupoint bean pressing(targeting the spleen,stomach,and sympathetic),and the control group was treated with postoperative routine nursing and sham ear acupoint bean pressing(containing no Vaccaria seed,targeting the spleen,stomach,and sympathetic).After the intervention,the time to first postoperative passing of flatus and defecation,clinical efficacy,and changes in gastrointestinal hormone levels were compared between the two groups.Results:The time to first postoperative passing of flatus[20.31(17.52,22.38)h vs.21.51(18.53,28.15)h]and defecation[35.32(31.47,39.17)h vs.38.12(33.44,42.78)h]in the experimental group was lower than that in the control group(P<0.05),and the clinical efficacy was better than that in the control group(P<0.05).There were no significant differ-ences in motilin(MTL),gastrin(GAS),somatostatin(SS),and substance P(SP)levels between the two groups before operation(P>0.05).The MTL and GAS levels were increased and the SS and SP levels were decreased after operation.The MTL[(451.52±54.33)pg/mL vs.(476.24±56.35)pg/mL]and GAS[150.50(133.93,164.52)pg/mL vs.173.44(154.45,184.63)pg/mL]levels at 24 h after operation in the experimental group were lower than those in the control group(P<0.05),and the SS[38.34(33.24,40.23)pg/mL vs.33.36(29.13,38.76)pg/mL]level at 24 h after operation was higher than that in the control group(P<0.05),with no significant change in the SP level(P>0.05).The results of repeated measures analysis of variance and generalized estimation equation showed that there were significant differences in the time effect and interaction effect of MTL(P<0.05),a significant difference in the time effect of SP(P<0.05),and significant differences in the time effect,intergroup effect,and interaction effect of GAS and SS(P<0.05).Conclusion:Ear acupoint bean pressing has significant effect on abdominal distension after laparoscopic surgery in patients with hysteromyoma,ef-fectively regulates the level of gastrointestinal motility related hormones,and promotes the recovery of gastrointestinal function.

Purpose To investigate the clinical,imaging,pathological features,differential diagnosis and prognosis of em-bryonic dysplastic neuroepithelial tumor(DNT).Methods The clinical data of 33 DNT patients were collected.Immunohis-tochemical results of Olig2,NeuN,Syn,GFAP,IDH1,CD34,BRAF V600E,H3K27M and Ki67 were examined by EnVision method.Histopathological morphology and immunohistochemical features were retrospectively analyzed and relevant literature was reviewed synchronously.Results A total of 28 cases were fol-lowed up,including 10 females and 18 males.The age of onset was 4～57 years,with average 24.97 years.Refractory epilepsy was a common symptom.The lesions were mainly located in the supratentorial cortex,and most of them were well-defined,lobu-lated,cystic or cystic and solid.Microscopically,DNT was mainly composed of oligodendrocytes,neurons floating in the mucous matrix,and proliferative astrocytes.Calcification was rare,and no necrosis or microvascular hyperplasia was ob-served.Immunohistochemistry showed that neurons expressed NeuN and Syn,oligodendrocytes expressed Olig2,and prolifera-tive astrocytes expressed GFAP;p53 was mostly wild-type,and the proliferation index of Ki67 was low(mostly less than 4％).Conclusion DNT is a benign tumor with mixed glial and neu-ronal structures.Precise pathological diagnosis needs to be care-fully considered with imaging characteristics,microscopic mor-phology,immunohistochemistry and molecular test results if nec-essary.Prognosis after complete surgical resection is good.

Purpose To investigate the clinical,imaging,pathological,and genetic characteristics of neuroepithelial tumors with EWSR1 translocation.Methods The clinicopatho-logical data of 6 patients with EWSR1 translocation in neuroepi-thelial tumors were collected,routine HE and immunohistochem-ical staining were performed,the information of high-throughput sequencing was summarized,and the relevant literature was re-viewed.Results The median age of the 6 patients was 11.5 years(ranging from 1.9 to 17 years),including 1 male and 5 females.The tumors located in temporal lobe,frontal lobe,pari-etal lobe,suprasellar region,or lateral ventricle.The clinical manifestations mainly started with seizures.Brain MRI showed abnormal signal focus in the cerebral hemisphere near the cortex in 4 cases,and ventricle/periventricular regions in 2 cases,with an almost clear boundary in 5 cases.Microscopically,the histo-logical changes were diverse,including low-grade gliomas/gli-oneuronal tumors in 3 cases,high-grade gliomas in 2 cases,and glioneuronal tumor with high-grade feature in 1 case.Immuno-histochemically,tumor cells expressed GFAP,S-100,Syn,and Olig2 partially.2 cases exhibited slightly positive of NeuN and 1 case exhibited little dot-like staining of EMA.Next generation sequencing revealed EWSR1 rearrangement in all 6 cases,with chaperone genes including PATZ1 in 5 cases,and PLAGL1 in 1 case.3 cases were treated with chemotherapy after surgery,and no recurrence or progression was found during follow-up.Con-clusion The neuroepithelial tumors with the fusion of EWSR1 and non-ETS commonly occur in the cerebral hemisphere of teenagers and children.Most of the boundaries lesion are still clear,the histomorphological spectrum is diverse,and the bio-logical behavior is presented as a low to moderate malignancy,which provides the possibility for expanding the molecular classi-fication of CNS neuroepithelial tumor.

Objective:To investigate the diagnostic value of lung ultrasound in hospitalized children with community-acquired pneumonia (CAP).Methods:In the cross-sectional study, a total of 422 children with CAP who were hospitalized in the Second Affiliated Hospital and Yuying Children′s Hospital of Wenzhou Medical University, from February 2021 to August 2022 and completed lung ultrasound examination within 48 hours after admission were enrolled. The clinical characteristics, lung ultrasound and chest CT were collected. The patients were divided into two groups according to the signs of pneumonia indicated by chest CT, and the signs of lung ultrasound with diagnostic value were screened according to the signs of pneumonia indicated by chest CT by least absolute shrinkage and selection operator (Lasso) regression. According to severity of the disease, the children were divided into the severe group and the mild group, and the differences of lung ultrasound signs between the two groups were compared. Kruskal-Wallis test, Fisher′s exact test was selected for comparison between groups. Random forest classifier wes used to evaluate the value of lung ultrasound in the diagnosis of CAP and prediction of severe pneumonia in children. The receiver operating characteristic curve was used to evaluate the prediction effect. Use DeLong test to compare the area under the curve.Results:Among the 422 cases of CAP, there were 258 males and 164 females, and the age of onset was 2.8 (1.3, 4.3) years. The confluent B-line, consolidation and pleural effusion detected by lung ultrasound were 309 cases (73.2%), 232 cases (55.0%) and 16 cases (3.8%), respectively, and the size of consolidation was 3.0 (0, 11.0) mm. One hundred and ten children (26.1%) with CAP completed chest CT. There were 90 cases with signs of pneumonia in chest CT and 20 cases without signs of pneumonia. Lasso was used for feature selection.Lung consolidation ( OR=2.46), bilateral lung consolidation ( OR=1.16) and confluent B-line ( OR=1.34) were the main index. With random forest classifier, the accuracy of models using full variables and Lasso-selected variables were 0.79 (95% CI 0.70-0.86) and 0.79 (95% CI 0.70-0.86), the sensitivity were 0.81 and 0.81, and the specificity were 0.75 and 0.70, and the area under curve were 0.87 (95% CI 0.81-0.94, P<0.001) and 0.84 (95% CI 0.76-0.91, P<0.001), respectively. There were 97 cases in severe group and 325 cases in mild group. Compared with the mild group, the detection rate of consolidation, multiple consolidation, the size of consolidation and the size of consolidation was adjusted by body surface area (consolidation size/body surface area) in severe group were higher (66 cases (68.0%) vs. 166 cases (51.1%), 42 cases (43.3%) vs. 93 cases (28.6%), 8.0 (0, 17.0) vs. 1.0 (0, 9.0) mm, 12.5 (0, 24.6) vs. 2.1 (0, 17.6), χ2=8.59, 9.98, Z=14.40, 12.79, all P<0.05). Using lung ultrasound lung consolidation size and consolidation size/body surface area to predict the severe CAP, the optimal cut-off value were 6.7 mm and 10.2, the accuracy was 0.80 (95% CI 0.75-0.83) and 0.89 (95% CI 0.86-0.92), the sensitivity was 0.99 and 0.99, the specificity was 0.14 and 0.56, respectively, and the area under the curve was 0.66 (95% CI 0.60-0.72, P<0.001) and 0.76 (95% CI 0.70-0.83, P<0.001), respectively. The area under the curve of consolidation size/body surface area was higher than that of consolidation size ( Z=5.50, P<0.001). Conclusions:Consolidation and confluent B-line, are important index for lung ultrasound diagnosis of CAP in children. The actual consolidation size adjusted by body surface area is superior to the size of consolidation in predicting severe CAP.

Objective To explore the pain catastrophizing (PC) level of pain in patients with multiple fractures and its influencing factors. Methods A convenience sampling method was used to investigate 156 patients with multiple fractures in the orthopedic trauma department of the First Affiliated Hospital of Nanjing Medical University. The questionnaire included a general information survey, a Digital Pain Rating Scale, PC scale, Positive and Negative Emotion Scale, and Social Rating Scale. Results The average PC score of patients with multiple fractures was (23.22±12.05), with 27 patients (17.20%) reaching the PC level. The average score of the Digital Pain Rating Scale was (6.30±1.49), the score of the Positive Emotion Scale was (27.92±6.06), the score of the Negative Emotion Scale was (23.18±7.00), and the total score of the Social Rating Scale was (27.90±4.61). The results of multiple linear regression analysis showed that pain score, negative emotion level, and social support level had predictive effects in PC among patients with multiple fractures. Conclusion The incidence of PC among patients with multiple fractures is at a moderate to high level. Patients with high pain scores, high negative emotion scores, and low social support are more likely to develop PC.

A new definition of metabolic dysfunction-associated fatty liver disease (MAFLD) has recently been proposed. We aim to examine the associations of MAFLD, particularly its discordance from non-alcoholic fatty liver disease (NAFLD), with the progression of elevated brachial-ankle pulse wave velocity (baPWV) and albuminuria in a community-based study sample in Shanghai, China. After 4.3 years of follow-up, 778 participants developed elevated baPWV and 499 developed albuminuria. In comparison with the non-MAFLD group, the multivariable adjusted odds ratio (OR) of MAFLD group for new-onset elevated baPWV was 1.25 (95% confidence interval (CI) 1.01-1.55) and 1.35 (95% CI 1.07-1.70) for albuminuria. Participants without NAFLD but diagnosed according to MAFLD definition were associated with higher risk of incident albuminuria (OR 1.77; 95% CI 1.07-2.94). Patients with MAFLD with high value of hepamet fibrosis score or poor-controlled diabetes had higher risk of elevated baPWV or albuminuria. In conclusion, MAFLD was associated with new-onset elevated baPWV and albuminuria independently of body mass index, waist circumference, and hip circumference. Individuals without NAFLD but diagnosed as MAFLD had high risk of albuminuria, supporting that MAFLD criteria would be practical for the evaluation of long-term risk of subclinical atherosclerosis among fatty liver patients.

OBJECTIVE: To investigate the effect and mechanism of tea polyphenol (TP) on the proliferation, apoptosis, migration and invasion of nasopharyngeal carcinoma(NPC) cell line HONEl. METHOD: After treated with different concentration of tea polyphenol, CCK-8 assay, fluorescent staining, cell scratching assay and transwell assay were applied to detect the effect of tea polyphenol on the HONE1 cells. Furthermore, the expression of protein VEGF was investigated by flow cytometry assay. RESULT: It was found that tea polyphenol could inhibit NPC cell proliferation significantly in a dose-dependent manner, however, little impact was observed in normal nasopharyngeal epithelial cell line NP69. Furthermore, it was demonstrated by fluorescent staining assay that tea polyphenol could induce NPC cell apoptosis, and cell scratching assay and transwell assay showed that tea polyphenol could inhibit cell migration and invasion. CONCLUSION Tea polyphenol can significantly inhibit cell proliferation, induce cell apoptosis and decreased the migration and invasion ability of NPC cells in vitro. Tea polyphenol might be a tumor suppressor of NPC cells.
