BackgroundIn recent years， the incidence of depression among adolescents has been increasing steadily， posing a serious threat to their physical and mental health and even leading to severe consequences such as self-harm and suicide. At the same time， the detection rate of subclinical depression symptoms among adolescents is even higher. Although these symptoms do not meet the clinical diagnostic criteria， they have significantly affected their quality of life， and their persistence over time may further develop into depression. Therefore， in-depth exploration of adolescent depression symptoms and the predictive factors holds significant practical significance and research value. However， up to now， no large-scale investigation and research on depression symptoms among children and adolescents has been conducted in Inner Mongolia Autonomous Region. ObjectiveTo understand the prevalence of depressive symptoms among children and adolescents in Inner Mongolia Autonomous Region， in order to provide references for formulating scientific and effective prevention strategies and intervention measures. MethodsBy using the cluster stratified random sampling method， 6 281 students from the third grade of primary school to the second grade of high school in 12 leagues and cities of Inner Mongolia Autonomous Region were selected in March 2024. A self-designed questionnaire and the Self-rating Depression Scale （SDS） were used for on-site investigation. ResultsA total of 6 058 （96.45%） children and adolescents completed the valid questionnaire survey， and 2 728 cases （45.03%） were found to have depressive symptoms. There were statistically significant differences in the detection rates of depressive symptoms among children and adolescents of different genders， ages， whether they were only children， different family types， family monthly income， parents' educational levels， and whether the mother was employed （χ²=33.769， 40.618， 48.593， 29.972， 142.648， 195.999， 168.190， 5.445， P<0.05 or 0.01）.The results of the Logistic regression analysis showed that for children and adolescents， being female， aged between 12 and 16， over 16 years old， not being an only child， living in a reconstituted family， having a monthly family income of less than 5 000 yuan， and having parents with an education level of primary school or below were predictors of depressive symptoms （OR=1.241， 1.427， 1.273， 1.177， 1.549， 1.278， 1.462， 1.417， 1.514， 1.929， 1.660， 1.528， P<0.05 or 0.01）. ConclusionThe detection rate of depressive symptoms among children and adolescents in Inner Mongolia Autonomous Region is relatively high. Factors that may predict depressive symptoms in children and adolescents include female gender， ages between 12 and 16， ages over 16 years old， non-only children， families with a restructured structure， monthly family income of less than 5 000 yuan， and parents with an education level of primary school or below. ［Funded by Science and Technology Planning Project of the Inner Mongolia Autonomous Region （number， 2022YFSH0119）］

Breast cancer is one of the most common malignant tumors among women worldwide, with an increasing incidence rate year by year, making it a significant public health concern. With the continuous advancement of tumor biology research, N 6-methyladenosine (m 6A) modification, as an important form of RNA modification, has attracted growing attention. The m 6A modification, the most prevalent RNA modification in eukaryotes, occurs in almost all types of RNA and plays a critical role in the occurrence, progression, and metastasis of breast cancer. It influences cell proliferation, apoptosis, and alterations in the tumor microenvironment, though the specific mechanisms underlying these effects require further in-depth investigation. Moreover, the specific patterns of m 6A modification demonstrate its potential as a novel biomarker for breast cancer, which could provide new directions for early diagnosis and prognosis evaluation.

ObjectiveTo investigate the incidence and relevant factors of visual acuity abnormalities in preschool children undergoing kindergarten entrance physical examinations in Shannan City, Xizang, in 2022, so as to formulate policies for protecting children’s visual acuity and provide a basis for optimizing the children’s health service system in this region. MethodsA cross sectional study was conducted among the children undergoing kindergarten entrance physical examinations in Shannan City in 2022. A diopter examination was performed for these children, and a questionnaire survey was administered to their caregivers. Additionally, factors affecting children’s visual acuity abnormalities were analyzed using the χ² test and binary logistic regression analysis. ResultsA total of 759 children were included in the analysis, with an incidence rate for visual acuity abnormalities of 11.20%. Univariate analysis showed that statistically significant differences were observed in the incidence rate for visual acuity abnormalities among preschool children in terms of different family monthly income (χ²=17.395, P<0.001), father’s education level (χ²=5.133, P=0.023), postnatal vitamin A and D supplementation (χ²=9.575, P=0.008), and feeding method within the first 6 months after birth (χ²=9.330, P=0.009). Multivariate analysis results indicated that family monthly income <5 000 yuan (OR=2.599, P=0.003), insufficient postnatal vitamin A and D supplementation (OR=1.912, P=0.011), and formula feeding (OR=2.131, P=0.010) were relevant factors for abnormal visual development in children. ConclusionThe incidence of visual acuity abnormalities in preschool children in Shannan City is slightly higher than that previously reported in other regions of Xizang. The occurrence of visual acuity abnormalities in children is related to factors such as family monthly income, postnatal vitamin A and D supplementation, and feeding method within the first 6 months after birth. Future interventions should be strengthened on the promotion and dissemination of knowledge related to eye use, such as improve parental awareness of eye care, promote timely vitamin A and D supplementation and encourage breast feeding for children after birth, more specifically, attentions need to be focused on the visual acuity problems of children from low-income families to safeguard the visual health in preschool children in Shannan City, Xizang.

BACKGROUND:Traditional Chinese medicine has been proved to have a significant role in anti-osteoporosis,and the effectiveness and mechanism of Ligustri Lucidi Fructus and its the active ingredients against osteoporosis have gradually gained the attention of scholars.OBJECTIVE:To analyze and summarize the research progress of Ligustri Lucidi Fructus and its active ingredients against osteoporosis in vitro and in vivo.METHODS:We searched the relevant literature included in CNKI and PubMed databases using the search terms of"Osteoporosis,Bone marrow mesenchymal stem cells,Osteoblast,Osteoclast,Ligustri Lucidi Fructus,Signal path"in Chinese and English,respectively.According to the needs of the research,we established the corresponding criteria and screened the literature.A total of 82 papers were included in the final review.RESULTS AND CONCLUSION:(1)The active ingredients of Ligustri Lucidi Fructus that exert anti-osteoporotic effects in vitro and in vivo mainly involve the following:Salidroside activates the Wnt/β-catenin signaling pathway by inhibiting the expression of Sclerostin and Dickkopf-related protein 1.This activation process enhances the expression of phosphorylated low-density lipoprotein receptor-related protein 6 in ovariectomized rats and primary osteoblasts,while decreasing the expression of glycogen synthase kinase 3β.Further,it promotes the expression of β-catenin,runt-related transcription factor 2 and cellular myelocytomatosis oncogene in the nucleus,thereby promoting the bone formation capacity of osteoblasts.The advantage is that it acts directly on osteoblasts to promote bone formation,which provides a new strategy for the treatment of osteoporosis.(2)Olive bittersweet significantly increases bone mineral density and regulates bone metabolism by decreasing terminal interleukin-6 and alkaline phosphatase concentrations in Sprague-Dawley rats.In vitro experiments showed that olive bittersweet promotes the proliferation of osteoblasts and up-regulates the protein and mRNA expression of osteoprotegerin,while inhibiting the protein and mRNA expression of receptor activator of nuclear factor-κB ligand.This mechanism of action is closely related to the regulation of the balance of the osteoprotegerin/receptor activator of nuclear factor-κB ligand system,demonstrating the advantage of increasing bone mineral density and maintaining bone health by regulating factors related to bone metabolism,but there is no significant effect on Ca2+concentration,which may limit its use in some specific types of osteoporosis.(3)By decreasing the expression of phosphatidylinositol 3 kinase,reducing the phosphorylation of protein kinase B and the expression of osteoclast-specific marker protein c-Fos,pineconiferin effectively inhibits the activation of phosphatidylinositol 3 kinase/protein kinase B/c-Fos pathway in osteoclasts.This inhibition reduces the proliferation and maturation of osteoclasts,which can help to reduce bone resorption.The advantage of this inhibition is that it can directly target osteoclasts,which provides a new target for osteoporosis treatment.However,the specific regulatory mechanism of osteoclasts needs to be studied in depth,and its long-term effect and safety need to be further evaluated.(4)The active ingredients of Ligustri Lucidi Fructus have shown good therapeutic effects on osteoporosis,but their mechanism of action is complex,involving the interaction of multiple genes,proteins and signaling pathways.In the future,large-scale clinical trials need to be carried out to verify its effectiveness and safety,and the strategy of combining the active ingredients of Ligustri Lucidi Fructus with other drugs needs to be further explored in order to obtain better therapeutic effects.

Objective:To investigate the clinical effect of microplasma radiofrequency combined with oral traditional Chinese medicine (TCM) Babao Dan capsule to improve damp-heat TCM constitution in the treatment of hypertrophic scar.Methods:A prospective randomized controlled trial method was used to recruit patients diagnosed with damp-heat TCM constitution and suffering from hypertrophic scar who admitted to the Fourth Medical Center of Chinese PLA General Hospital from March to July 2024. All patients were randomly divided into microplasma radiofrequency combined with TCM treatment group (combination group), microplasma radiofrequency (RF) treatment group (RF group), and oral TCM treatment group (TCM group). Both the combination group and the RF group were treated with a microplasma radiofrequency instrument. Transverse, longitudinal and oblique scar grinding were performed three times with 90 W power, and regular scabs appeared in the treatment area as the treatment end point. After RF treatment in the combination group and the TCM group, Babao Dan capsule was taken with regular warm water, 0.6 g each time, 3 times/day, for 3 months. The Vancouver scar scale (VSS) score (higher score indicating more severe scar), visual analogue scale (VAS) of scar pain and itch (higher score indicating more severe symptom), and TCM constitution score (higher score indicating more severe moist heat constitution) were compared before treatment and 3 months after the first treatment. SPSS 26.0 software was used for statistical analysis. Measurement data conforming to normal distribution were expressed as Mean±SD, ANOVA was used for comparison among groups, and LSD- t method was used for pair comparison between groups. Paired sample t test was used before and after treatment in the same group. Counting data were expressed as cases (%), and the χ2 test was used for inter-group comparison. P<0.05 was considered statistically significant. Results:A total of 60 patients were included, 20 in each group. There were no significant differences in gender distribution, disease course, scar area and distribution among the three groups ( P>0.05), indicating comparability. Before treatment, there were no statistically significant differences in VSS, VAS and TCM physique scores among the 3 groups ( P>0.05). After treatment, VAS scores in the 3 groups, VSS scores in combination group and RF group, TCM physique scores in combination group and TCM group were improved compared with those before treatment, and the differences were statistically significant ( P<0.05). The VSS score of the combination group was significantly lower than that of the RF group and the TCM group ( P<0.05), but there was no statistical significance between the RF group and the TCM group ( P>0.05). The pruritus VAS score of the combination group was significantly lower than that of TCM group and RF group ( P<0.05), but there was no statistical significance between RF group and TCM group ( P>0.05). There was no significant difference in pain VAS scores among the three groups after treatment ( P>0.05). The TCM physique scores of the combination group and TCM group were significantly lower than those of the RF group ( P<0.01), but there was no statistical significance between the combination group and TCM group ( P>0.05). Conclusion:Microplasma radiofrequency combined with oral Babao Dan capsule can effectively improve the VSS score, pain and pruritus of hypertrophic scars in patients with damp-heat constitution, and the effect is better than that of radiofrequency or TCM alone.

Objective:To establish and validate a nomogram for postoperative disease progression (including recurrence, metastasis, and death) in patients with primary liver cancer (PLC) based on quantitative CT measurements of relevant indicators.Methods:Clinical data of 290 patients with PLC admitted to Zhongshan Hospital Affiliated to Fudan University and Kunshan Hospital Affiliated to Jiangsu University from January 2016 to December 2021 were retrospectively collected, including 177 males and 113 females, aged (60.3±11.9) years. Two hundred and three patients admitted to Zhongshan Hospital Affiliated to Fudan University were used as the training set, and 87 patients admitted to Kunshan Hospital Affiliated to Jiangsu University were used as the validation set. The patient's condition of ascites , tumor length, number of lesions, tumor differentiation degree, relevant indicators of quantitative CT detection (including decreased muscle mass and increased intra-abdominal fat area), prognosis and other clinical data were recorded. The influencing factors of postoperative disease progression was analyzed through multiple logistic regression in the training set, and the nomogram model was constructed based on the results of multiple factor analysis. The predictive performance of the model was evaluated using receiver operating characteristic (ROC) curves and calibration curves. The clinical applicability of predictive models was evaluated using the decision curve analysis.Results:The results of multiple logistic regression analysis showed that the increase in maximum tumor diameter ( OR=1.519, 95% CI: 1.251-1.843), multiple lesions ( OR=3.193, 95% CI: 1.493-6.830), low tumor differentiation ( OR=5.604, 95% CI: 2.442-12.863), ascites ( OR=3.321, 95% CI: 1.166-9.463), portal vein tumor thrombus ( OR=3.990, 95% CI: 1.681-9.474), decreased muscle mass ( OR=2.173, 95% CI: 1.051-4.492) and increased intra-abdominal fat area ( OR=2.634, 95% CI: 1.276-5.438) were independent risk factors for postoperative disease progression in patients with PLC (all P<0.05). A nomogram was constructed based on the above variables, and the area under the ROC curve for predicting postoperative disease progression in patients with PLC in the training set and validation set was 0.862 (95% CI: 0.810-0.914) and 0.879 (95% CI: 0.806-0.953), respectively. The calibration curve and ideal curve fit well, indicating that the predicted situation was basically consistent with the actual situation. Decision curve analysis showed that the column chart model had a high clinical net benefit and good clinical prediction effectiveness. Conclusion:The nomogram constructed based on the maximum diameter of the tumor, the number of lesions, the degree of tumor differentiation, ascites, portal vein tumor thrombus, decreased muscle mass, and increased intra-abdominal fat area has good predictive power for postoperative disease progression in patients with PLC.

Objective:To explore the risk factors for complications of facial autologous fat transplantation.Methods:A total of 51 female patients (case group) with moderate to severe complications following facial autologous fat transplantation at the Fourth Medical Center of Chinese PLA General Hospital from November 2016 to October 2022 were included in this retrospective study. The median age was 31.0 (27.0, 40.0) years. After age and surgical date were matched with ratio of 1∶1, a total of 51 female patients who received autologous fat transplants at several official medical facilities and experienced no complications within a year after the procedure made up the control group. The median age of the control group was 32.0 (26.0, 41.0) years. The clinical characteristics of the two groups were compared, and the factors for complications of facial autologous fat transplantation were examined using a multivariate logistic regression model.Results:In the case group, complications included facial artery embolism (7 cases), ophthalmic artery embolism (19 cases), infection (19 cases), and fat necrosis (6 cases), with 26 severe and 25 moderate cases. No significant differences were found between the two groups in age, body mass index (BMI), marital status, history of hypertension, infectious diseases, allergies, smoking, or alcohol consumption (all P>0.05). However, significant differences were observed in a history of facial surgery, perimenstrual phase, surgical site, and fat donor site (all P<0.05). Multivariate logistic regression analysis revealed that a history of facial surgery ( OR=17.289, 95% CI: 4.851-61.616, P<0.001) and the surgical site being a clinic/outpatient department (compared to a hospital, OR=7.708, 95% CI: 2.482-23.939, P<0.001) were risk factors for postoperative complications after facial autologous fat transplantation. Conclusion:A history of facial surgery and the surgical site being a clinic/outpatient department (compared to a hospital) are risk factors for complications of facial autologous fat transplantation.

OBJECTIVE: To observe the effect of electroacupuncture at "Sishencong" (EX-HN1) and "Fengchi" (GB20) on hippocampal neuronal ferritinophagy mediated by the nuclear receptor coactivator 4 (NCOA4)/ferritin heavy chain 1 (FTH1) signaling pathway in vascular dementia (VD) rats, and to explore the potential mechanisms of electroacupuncture for VD. METHODS: A total of 60 male rats of SPF grade were randomly divided into a blank group (12 rats), a sham surgery group (12 rats) and a modeling group (36 rats). In the modeling group, the modified 4-vessel occlusion method was used to establish the VD model. The 24 successfully modeled rats were randomly divided into a model group and an electroacupuncture group, with 12 rats in each group. In the electroacupuncture group, electroacupuncture was applied at left and right "Sishencong" (EX-HN1), and bilateral "Fengchi" (GB20), with continuous wave, in frequency of 2 Hz and current intensity of 1 mA, 30 min a time, once daily for 21 consecutive days. The learning and memory abilities were assessed using the Morris water maze test before modeling, after modeling and after intervention, as well as the novel object recognition test after intervention. After intervention, the neuronal morphology in the hippocampus was observed by Nissl staining; the iron deposition was observed by Prussian blue staining; the reactive oxygen species (ROS) level was detected by dihydroethidium (DHE) fluorescence staining; the levels of iron, malondialdehyde (MDA) and superoxide dismutase (SOD) in the hippocampal tissue were measured by the colorimetric assay, TBA method, and WST-1 method, respectively; the positive expression of NCOA4, FTH1 and glutathione peroxidase 4 (GPX4) was detected by immunohistochemistry; the protein expression of NCOA4, FTH1, GPX4, and the ratio of microtubule-associated protein 1 light chain 3B (LC3B) Ⅱ/Ⅰ in the hippocampus were detected by Western blot. RESULTS: Compared with the sham surgery group, in the model group, the escape latency was prolonged, and the number of platform crossings reduced (P<0.01), the recognition index (RI) was decreased (P<0.01); the hippocampal neurons displayed a blurred laminar structure, disorganized cellular arrangement, and the number of Nissl bodies was decreased (P<0.01); the percentage of iron deposition area in the hippocampus was increased (P<0.01); in the hippocampus, the levels of ROS, iron, MDA, and the protein expression of NCOA4, as well as the LC3B Ⅱ/Ⅰ ratio were increased (P<0.01), the SOD level, and the protein expression of FTH1 and GPX4 were decreased (P<0.01). Compared with the model group, in the electroacupuncture group, the escape latency was shortened and the number of platform crossings was increased (P<0.01), the RI was increased (P<0.01); the hippocampal neurons exhibited more regular morphology, better-organized cellular structure, and the number of Nissl bodies was increased (P<0.05); the percentage of iron deposition area in the hippocampus reduced (P<0.01); in the hippocampus, the levels of ROS, iron, MDA, and the protein expression of NCOA4, as well as the LC3B Ⅱ/Ⅰ ratio were decreased (P<0.01, P<0.05), the SOD level, and the protein expression of FTH1 and GPX4 were increased (P<0.01). CONCLUSION Electroacupuncture at "Sishencong" (EX-HN1) and "Fengchi" (GB20) can improve learning and memory abilities in VD rats, and its mechanism may be associated with the regulation of the hippocampal NCOA4/FTH1 signaling pathway, inhibition of ferritinophagy, and alleviation of oxidative stress damage.
