Objective: To explore the correlation between traditional Chinese medicine (TCM) constitution and depressive symptom among school aged children and adolescents, so as to provide evidences for informing constitution based regulation and prevention of depressive symptom. Methods: From June to December 2024, a total of 4 729 students aged 6-14 were recruited by cluster random sampling from 10 primary schools in Baoding (Hebei Province), Heze and Liaocheng (Shandong Province). General information, TCM constitution and depressive symptom were collected. Restricted cubic spline (RCS) models were used to analyze related factors and threshold effects of depressive symptom. Binary Logistic regression was applied to examine the association between depressive symptom and TCM constitution, with subgroup analyses conducted. Results: The detection rate of depressive symptom among the included children and adolescents was 25.82%. RCS analyses indicated non linear associations between depressive symptom and age (inflection point at 10 years old), bedtime (inflection point at 22:00), and wake up time (inflection point at 6:30 ) (all P non linearity <0.01). Linear associations were observed with body mass index (BMI) and sleep duration (all P non linearity > 0.05 ). After adjusting for covariates such as age, BMI and sleep status, binary Logistic regression analyses showed that Yin deficient constitution ( OR =1.26, 95% CI =1.09-1.45) and Phlegm-dampness constitution ( OR =1.42, 95% CI =1.11-1.82) were significantly associated with depressive symptom among children and adolescents (all P <0.05). Conclusions Depressive symptom among school aged children and adolescents is primarily associated with Yin deficiency and Phlegm dampness constitutions in TCM constitution. Active attention should be paid to susceptible TCM constitution among children and adolescents. Targeted health guidance and interventions should be implemented to improve TCM constitution health status for preventing the occurrence of depressive symptom.

Objective To develop and validate a scoring system to predict the possibility of laparoscopic cholecystectomy (LC) conversion to laparotomy based on preoperative clinical data, and to establish a grading management model of surgery. Methods A retrospective analysis was conducted on the clinical data of 9 414 patients who underwent LC at Renhe Hospital and Huashan Hospital from June 2013 to June 2018. The patients were divided into two groups: the LC group (9 246 patients who successfully underwent LC) and the conversion to laparotomy group (168 patients who required conversion to open surgery). The data of two groups were compared, and the risk factors affecting conversion to laparotomy were screened out by single factor analysis of Chi-square test. Then, the risk factors were analyzed by multiple Logistic regression, and the pre-coefficient of each variable of the risk factors was assigned according to the established conversion to laparotomy possibility function. After calculating the score of each case, the difference in the actual conversion rate of each group was compared. The area under receiver operating characteristic (ROC) curve was calculated to evaluate the performance of the scoring system. According to the scoring system, LC surgical grading management model was created and verified. Results The following factors were identified as significant risk factors for conversion to laparotomy (P < 0.001): body temperature ≥ 38.5℃, frequency of acute cholecystitis ≥3 times, maximum thickness of gallbladder wall ≥ 5 mm, gallbladder neck stone incarceration, diameter of common bile duct ≥8 mm, and surgical experience ≤50 cases were the risk factors for conversion to laparotomy (P < 0.001). A score >3 points was associated with a high risk of conversion to laparotomy. Conclusions The LC scoring system and surgical grading management are reliable and effective tools for predicting and reducing the conversion rate of LC to laparotomy.

Objective:To explore the effect of fully automatic image segmentation of adenoid and nasopharyngeal airway by deep learning model based on U-Net network. Methods:From March 2021 to March 2022, 240 children underwent cone beam computed tomography（CBCT） in the Department of Otolaryngology, Head and Neck Surgery, General Hospital of Shenzhen University. 52 of them were selected for manual labeling of nasopharynx airway and adenoid, and then were trained and verified by the deep learning model. After applying the model to the remaining data, compare the differences between conventional two-dimensional indicators and deep learning three-dimensional indicators in 240 datasets. Results:For the 52 cases of modeling and training data sets, there was no significant difference between the prediction results of deep learning and the manual labeling results of doctors（P>0.05）. The model evaluation index of nasopharyngeal airway volume: Mean Intersection over Union（MIOU） s （86.32±0.54）%; Dice Similarity Coefficient（DSC）: （92.91±0.23）%; Accuracy: （95.92±0.25）%; Precision: （91.93±0.14）%; and the model evaluation index of Adenoid volume: MIOU: （86.28±0.61）%; DSC: （92.88±0.17）%; Accuracy: （95.90±0.29）%; Precision: （92.30±0.23）%. There was a positive correlation between the two-dimensional index A/N and the three-dimensional index AV/（AV+NAV） in 240 children of different age groups（P<0.05）, and the correlation coefficient of 9-13 years old was 0.74. Conclusion:The deep learning model based on U-Net network has a good effect on the automatic image segmentation of adenoid and nasopharynx airway, and has high application value. The model has a certain generalization ability.

Objective:To explore the effect of alcohol abstinence intervention based on timing theory on patients with alcoholic liver disease.Methods:A total of 106 patients with alcoholic liver disease hospitalized in the Department of liver disease of Taian Medical District, 960th Hospital of Chinese PLA from July 2018 to June 2019 were selected by convenience sampling method and divided into observation group and control group by random digits table method, 53 cases in each group. The control group received routine nursing, and through the improvement of patients' cognition and support system, implemented short abstinence intervention during hospitalization; the observation group received abstinence intervention based on timing theory on the basis of the control group intervention. At 1 month and 6 months after discharge, the differences of rehydration rate, alcohol dependence and physical and mental status between the two groups were compared.Results:Finally, 49 cases in the control group completed the study, and 51 cases in the observation group completed the study. The rehydration rates of the observation group were 21.57%(11/51) and 15.69%(8/51) respectively at 1 month and 6 months after discharge, while those of the control group were 40.82%(20/49) and 36.73%(18/49) respectively at 1 month and 6 months after discharge. The difference was statistically significant ( χ2 values were 4.328, 5.754, P<0.05). The alcohol dependence scores were 0(2,3), 0(1,2) in the observation group and 2(0,3), 3(1,4) in the control group at 1 month and 6 months after discharge, and the difference was statistically significant ( Z values were -6.719, -7.345, P<0.01). There was no significant difference in the score of Symptom Checklist-90(SCL-90) before intervention and 1 month after discharge between the two groups ( P>0.05). Six months after discharge, the score of SCL-90 was 8.26 ± 1.37 in the observation group and 10.11 ± 1.68 in the control group, and the difference was statistically significant( t value was 6.046, P<0.01). Conclusions:The application of timing theory in alcohol abstinence of patients with alcoholic liver disease can significantly reduce the relapse rate and the degree of alcohol dependence of patients with alcoholic liver disease, improve the physical and mental state of patients.

Objective:To systematically review the barriers encountered by nursing staff in the implementation of early activities in adult ICU units.Methods:A systematic search was conducted on CNKI, Wanfang Database, VIP Database, China Biomedical Database, PumMed, Web of Science, Cochrane Library and EMBASE for the research on the obstacles of early activity nursing implementation in adult ICU from the establishment of the database to July 2020, and the final integrated analysis of the included literature was carried out.Results:A total of 26 articles were included, and 59 obstacles in 5 categories were integrated, including 6 kinds of technical level, 13 kinds of organizational culture level, 7 kinds of personnel level, 4 kinds of structural level, and 29 kinds of 6 sub categories of patients level. The most frequent obstacles were unstable condition of patients, sedation or continuous deep sedation, low staffing level, disturbance of consciousness of patients, insufficient equipment related to early activities, and low willingness or compliance of patients to participate.Conclusion:The nursing staff are facing with many obstacles in guiding and assisting ICU adult patients to carry out early activities. It is necessary to formulate modified policies aiming at changeable factors in order to promote the application of early activities in adult ICU units.

Objective:To systematically evaluate the real breastfeeding experience in professional women.Methods:Qualitative studies on breastfeeding experience and needs in professional women which were published up to August 20, 2020 were retrieved from English databases such as PubMed, Medline, The Cochrane Library, Embase, Web of Science, Ovid, CINAHL, Joanna Briggs Institute Library, Chinese databases such as CNKI, Wanfang, VIP, SinoMed, and grey literature databases like ProQuest. After literature screening and evaluation, a collection integration method was used to integrate the results.Results:A total of 12 studies were included, and 57 complete research results were extracted, which were summarized into 8 new categories integrated into 3 new results: working mothers benefited from breastfeeding but also had negative experience due to returning to work; their breastfeeding was affected by multiple promotion and obstacles after returning to work; and they dealt with breastfeeding challenges after returning to work through self-management.Conclusions:We should actively pay attention to the breastfeeding experience of professional women, improve the support for breastfeeding of working mothers, and help them improve their self-management ability, in order to promote their breastfeeding behavior after returning to work.

Objective To evaluate the stability of U6 and let-7a as internal reference genes of miRNAs in RTqPCR by using femoral head samples of cartilage tissue from inbred DA rats.Methods Total RNA was extracted from femoral head cartilage tissues of female DA rats at three different time points,i.e.at birth (D0),ablactation (D21) and maturation (D42).The expressions of different miRNAs (miR-1,-25,-26a,-140,-146a,-150,-181a,-195,-223 and-337) were detected by RT-qPCR using U6 or let-7a as the internal reference.The two sets of miR expression were compared with the results from Solexa sequencing in our pioneer work to evaluate the stability of the two internal references.Results The relative values of U6 (P =0.045) and let-7a (P =0.021 5) revealed significant difference in the D42 sample.Both in U6 and let-7a systems,miR-26a,-140,-223,and-337 showed a similar tendency in expression and quantification but miR-1 and-146a did not have significant differences.miR-25,-150,-181a and-195 differed significantly (P＜0.05).Comparison of absolute quantification results between the two generations' sequencing showed that let-7a is more stable than U6.Conclusion Let-7a is more suitable to be used as the internal reference gene in RT-qPCR for miRNAs in cartilage tissue.
