Objective: To explore the application effect of a guided self help intervention based on dialectical behavior therapy (DBT) to address non suicidal self injury (NSSI) behavior among college students, so as to provide a reference for reducing the occurrence of NSSI behavior in this population. Methods: A total of 106 college students with NSSI admitted to the Department of Child and Adolescent Psychology, the Second Affiliated Hospital of Jining Medical University from January 2021 to January 2023 were selected and divided into an observation group and a control group, with 53 cases in each group, using a random number table method. The control group received routine medication treatment and psychological intervention, while the observation group, on the basis of the interventions provided to the control group, implemented dialectical behavior therapy based guided self help. The approach combines group activities, individual counseling, and selfdirected learning, covering four core modules: mindfulness training, distress tolerance, interpersonal effectiveness, and emotion regulation. Meanwhile, data collection, skill check ins, and personalized recommendation pushes were conducted through a WeChat. Both groups were intervented for 12 weeks. Before the intervention and after the intervention, the Adolescent Non suicidal Self injury Behavior Questionnaire, Ottawa Self injury Inventory (OSI), and Barratt Impulsiveness Scale (BIS) were used to evaluate the patients, and the levels of serum neurotransmitters were detected. The χ 2 test, t test, and Cochran s Q test were used for data comparison and analysis. Results: The incidence rates of NSSI in the observation group after 3, 6, and 12 weeks of intervention were 47.17%, 16.98%, and 5.66%, respectively, all lower than those in the control group (67.92%, 35.85%, 20.75%) ( χ 2=4.67, 4.85, 5.27,all P <0.05). After 12 weeks of intervention, in the NSSI Behavior Questionnaire, the total score of the observation group was (17.94±2.69) points, which was lower than that of the control group (23.04±5.11) points; in the Function Questionnaire, the total score of the observation group was (53.24±8.94) points, which was higher than that of the control group (47.74±8.00) points（both P ＜0.05）. In terms of the OSI, the total score of the observation group was (4.49±0.62) points, lower than that of the control group (6.25±0.81) points;in the BIS, the total score of the observation group was (80.76±7.94) points, lower than that of the control group (87.74±9.34) points，and the differences between groups were statistically significant(both P<0.05). After the intervention, the level of 5-hydroxytryptamine in the observation group was (67.93±5.42) ng/mL, higher than (44.72±5.54) ng/mL of the control group; the levels of substance P and cortisol in the observation group were (35.82±4.47) ng/L and (75.64±8.02) μg/L, respectively, both lower than (48.14±5.32) ng/L and (94.53±10.78) μg/L of the control group, and the differences were statistically significant (all P <0.05). Conclusion The guided self help intervention based on DBT is helpful for reducing NSSI behavior among college students.

ObjectiveTo explore the epidemic levels and epidemiological characteristics of influenza-like illness (ILI) in Hongkou District of Shanghai, to track the trends in virus mutations, so as to offer a scientific foundation for precisely predicting influenza epidemic trends, providing early alerts, and implementing prompt prevention and control measures. MethodsData on ILI and etiological surveillance from Hongkou District between 2015 and 2024 were collected and statistically analyzed. ResultsThe consultation percentage of ILI (ILI%) in Hongkou District from 2015 to 2024 was 0.58%, and the differences were statistically significant between different years (χ²=19 280.500, P<0.001), with winter and summer being the prevalence peaks. The highest proportion of ILI cases was observed in the 25‒<60 years age group, and the proportion of cases aged ≥60 years showed an increasing trend. The positive rate for influenza viruses was 17.60%, with seasonal influenzaA (H3N2) subtype (49.78%) and influenza A(H1N1) (30.03%) being the predominant strains,and the positive rate was different by years. There was a correlation between ILI% and the positive rate of influenza viruses (r=0.260, P<0.001). The median intensity of influenza activity in 2023‒2024 was 23.09, which was significantly higher than that in 2015‒2019 (H=37.052, P<0.001) and that in 2020‒2022 (H=40.436, P<0.001). ConclusionFrom 2015 to 2022, the ILI% in Hongkou District, Shanghai remained at a relatively low level, but it significantly increased in 2023‒2024, with peaks observed in winter and summer. The predominant influenza virus strains varied and alternated by years. The 2023‒2024 period witnessed an intensified influenza activity. It is necessary to continuously monitor the impact of other respiratory pathogens on influenza epidemic, so as to provide a scientific basis for early warning and prevention and control of influenza.

A strategy combining a tailored database and high-throughput activity screening that discover bioactive metabolites derived from Magnoliae Officinalis Cortex (MOC) was developed and implemented to rapidly profile and discover bioactive metabolites in vivo derived from traditional Chinese medicine (TCM). The strategy possessed four characteristics: 1) The tailored database consisted of metabolites derived from big data-originated reference compound, metabolites predicted in silico, and MOC chemical profile-based pseudomolecular ions. 2) When profiling MOC-derived metabolites in vivo, attentions were paid not only to prototypes of MOC compounds and metabolites directly derived from MOC compounds, as reported by most papers, but also to isomerized metabolites and the degradation products of MOC compounds as well as their derived metabolites. 3) Metabolite traceability was performed, especially to distinguish isomeric prototypes-derived metabolites, prototypes of MOC compounds as well as phase I metabolites derived from other MOC compounds. 4) Molecular docking was utilized for high-throughput activity screening and molecular dynamic simulation as well as zebrafish model were used for verification. Using this strategy, 134 metabolites were swiftly characterized after the oral administration of MOC to rats, and several metabolites were reported for the first time. Furthermore, 17 potential active metabolites were discovered by targeting the motilin, dopamine D2, and the serotonin type 4 (5-HT₄) receptors, and part bioactivities were verified using molecular dynamic simulation and a zebrafish constipation model. This study extends the application of mass spectrometry (MS) to rapidly profile TCM-derived metabolites in vivo, which will help pharmacologists rapidly discover potent metabolites from a complex matrix.

This experiment aims to screen and isolate bacteria for the domestication of macrophages and to identify their domestication effector molecules.Bacteria were isolated and purified from cow and sheep feces.The procedures included preparing fermentation supernatant and conducting ex-periments with a mouse peritoneal macrophage model.Nitric oxide(NO)levels were measured,tumor necrosis factor-alpha(TNF-α)was analyzed using ELISA,the domestication activity was e-valuated by mouse peritoneal macrophage model.The activated bacteria were subjected to 16S rRNA gene sequences identification,growth curves determination,and saturated ammonium sul-fate precipitation for NO assay and ELISA analysis of TNF-α to assess the phagocytic capability of domesticated macrophages against Staphylococcus aureus.One strain,ED-8,with immunomodula-tory polarizing properties was successfully isolated.Alignment of its 16S rRNA gene sequence showed 99.86％similarity with Streptococcus zooepidemicus,classifying it as such species.The fermentation supernatant significantly stimulated NO and TNF-a secretion in macrophages.The phagocytic capability against Staphylococcus aureus of macrophages polarized by ED-8 also en-hanced.This effect was retained after crude extraction,indicating the presence of immunomodula-tory activity.In this study,multiple animal chain streptococcus ED-8 was successfully isolated.Its secreted products were shown to induce the trained immunity of macrophages,enhancing their phagocytic activity.

The aim of this experiment was to investigate the effects of Chinese angelica polysaccha-ride(CAP)on peritoneal macrophage function before and after selenization.In the experiment,CAP and selenized Chinese angelica polysaccharide(sCAP)were applied to mouse peritoneal mac-rophages,and the phagocytic activity of macrophages as well as the expression of the cellular phe-notypes F4/80,MHC-Ⅱ,CD80 and CD86 were detected by flow cytometry,and the changes of IL-6,IL-10,NO,MIP-1α,and TNF-α content in the supernatant of macrophage were detected by ELISA.The results showed that the phagocytic activity of peritoneal macrophages was significantly higher in the sCAP mass concentration of 1.96 mg/L than in the other groups(P＜0.05);and the expression of F4/80,MHC-Ⅱ,CD80 and CD86 were significantly higher in the sCAP mass concen-tration of 1.96 mg/L than in the CAP group and cell control group(P＜0.05);the contents of IL-6,IL-10,NO,and MIP-1α in the supernatant of macrophages were significantly higher than those in other groups when the mass concentration of sCAP ranged from 7.81 to 1.96 mg/L(P＜0.05).The results showed that sCAP had an enhancing effect on the immunomodulatory function of ab-dominal macrophages and was optimal at a mass concentration of 1.96 mg/L.

Objective To observe the value of 18F-FDG PET/CT semi-quantitative parameters for predicting spread through air spaces(STAS)of clinical stage Ⅰa—Ⅲa lung adenocarcinoma.Methods Data of 85 patients with clinical stage Ⅰa—Ⅲ a lung adenocarcinoma who underwent preoperative 18F-FDG PET/CT were retrospectively analyzed.The patients were divided into positive group(n=23)or negative group(n=62)according to whether pathology showed STAS or not.Clinical and PET/CT data were compared between groups,and logistic analysis was performed to explore the efficacy of each parameter for predicting STAS.Results Significant differences of gender,carcinoma embryonic antigen,clinical stage,pathological grade,micropapillary growth and proportion were found between groups(all P＜0.05).The maximum,the mean,the peak standard uptake value(SUVmax,SUVmean,SUVpeak),as well as the maximum,the mean and the peak standard uptake value normalized by lean body mass(SULmax,SULmean,SULpeak),also the total lesion glycolysis(TLG)in positive group were all significantly higher than those in negative group(all P＜0.05).Patients'gender,proportion of micropapillary growth,SUVmax and SULmax were all independent risk factors of STAS of clinical stage Ⅰa—Ⅲa lung adenocarcinoma.The area under the curve(AUC)of the above parameters for predicting STAS was 0.666,0.912,0.839 and 0.842,respectively,and of the combination was 0.957.Conclusion 18 F-FDG PET/CT semi-quantitative parameters SUVmax and SULmax were helpful for predicting STAS of clinical stage Ⅰa—Ⅲ a lung adenocarcinoma,and further combination of gender and proportion of micropapillary growth could improve diagnostic efficacy.

Purpose To study the association between ultrasonography signs of midurethral sling(MUS)and postoperative bladder neck mobility,and urethral segmental mobility,to explore ultrasound parameters that measure the biomechanical effects of MUS and to analyze the relationship between them and the clinical outcomes.Materials and Methods This was a retrospective analysis of the clinical material and ultrasound imaging data of the patients who underwent MUS surgery and had postoperative clinic follow-up in the Second Xiangya Hospital,Central South University,from September 2017 to July 2022.According to the surgical outcome,all patients were divided into three groups:stress urinary incontinence(SUI)cure group,SUI recurrence group and postoperative voiding dysfunction(VD)group.Bladder neck mobility,urethral segmental mobility,MUS position,and sling-pubic gap(SPG)during maximal Valsalva manoeuvre were measured by pelvic floor ultrasound.Ultrasound results among the three groups were compared,respectively.The relationships between ultrasound signs of the sling(MUS position and SPG),bladder neck and urethral mobility,and the surgical outcomes were analyzed,respectively.Results A total of 117 women had valid data.The median follow-up interval was 10(6,18)months.On clinical examination and diagnosis,44 women(37.6％)had cured SUI,46(39.3％)had recurrence SUI,and 27(23.1％)had postoperative VD.The mean SPG of the 117 slings was(12.0±3.5)mm(range 4.7 to 23.0 mm),and the mean position of the MUS was the 53％(range 33％-75％).There was no significant difference in MUS position and SPG between the SUI cured group and the postoperative VD group(P＞0.05).The SUI recurrence group had farther MUS position[(56±11)％vs.(49±10)％,P=0.003]relative to the bladder neck and wider SPG[(13.9±3.7)mm vs.(11.2±2.7)mm,P＜0.001]than SUI cure group.No significant correlation was found between the ultrasound signs of MUS(MUS position and SPG)and bladder neck mobility(r=-0.138-0.205,all P≥0.05).MUS position and SPG were correlated with midurethral mobility(MUS position vs.point 2 and 3,r=0.322,0.322,both P＜0.01;SPG vss.point 3 to 6,r=0.288-0.434,all P＜0.01):the closer the MUS position was relative to the distal urethra,the higher the midurethral mobility.The wider the SPG,the higher the midurethral mobility.Logistic regression showed a positive correlation between SPG and SUI recurrence with an odds ratio(OR)of 1.401(95％CI 1.189-1.652,P＜0.001),and a negative correlation with postoperative VD with an OR of 0.755(95％CI 0.627-0.909,P=0.003).Conclusion SPG during the Valsalva manoeuvre can be used to measure the tightness of MUS.The larger the measured value of SPG,with the looser the MUS,the greater the likelihood of postoperative SUI recurrence,and the lower the risk of postoperative VD.

Objective:To explore the application value of contrast-enhanced ultrasound (CEUS) combined with transvaginal ultrasound features and quantitative parameters in evaluating high-risk endometrial cancer (EC).Methods:Retrospective analysis was made on 69 EC patients who received CEUS examination and were confirmed by surgery and pathology in Beijing Shijitan Hospital, Capital Medical University from December 2017 to September 2022. According to postoperative pathology, the patients were divided into low-risk group ( n=38) and high-risk group ( n=31). The differences in CEUS, transvaginal ultrasound features and quantitative parameters between the two groups were compared, relevant parameters that with predictive value for high-risk EC were screened, and these parameters were scored. Results:①There were differences in lesion size (thick diameter, long diameter), vascular morphology, and color blood flow score between high and low risk ECs (all P<0.05). ②There were differences in CEUS parameters [perfusion mode, enhancement intensity, area under curve(AUC)] between high and low risk EC groups (all P<0.05). ③The areas under the ROC curve for diagnosing high-risk EC were 0.79, 0.69, 0.69, and 0.62, respectively, based on the critical values of lesion thickness diameter ≥1.85 cm, lesion length diameter ≥2.05 cm, ultrasound contrast quantification parameter AUC ≥859 au, and enhancement intensity ≥29.4 dB. ④Using statistically significant parameters for scoring, the sensitivity and specificity for diagnosing high-risk EC with the score ≥5, were 70.97% and 89.47%, respectively. Conclusions:The combination of CEUS and transvaginal ultrasound is a feasible method for predicting high-risk EC. CEUS parameters (enhanced intensity, AUC, and " focal" perfusion mode) are related to high-risk EC. The combination of CEUS and transvaginal ultrasound helps to pre-evaluate the pathological prognostic factors of endometrial malignant lesions before surgery, providing a basis for clinical follow-up treatment.

Objective:To analyze changes in energy metabolism and oxylipin metabolism in macrophages after stimulation by Mycobacterium marinum ( M. marinum) using targeted metabolomics, and to provide insights into the mechanisms underlying the immune defense by macrophages against M. marinum infections. Methods:Mouse bone marrow-derived macrophages were obtained from the bilateral femurs of mice, and cultured cells were divided into two groups: the active M. marinum group and the inactivated M. marinum group. Bacterial suspensions were prepared using M. marinum clinical isolates; the active M. marinum group was treated with live M. marinum suspensions for 12 hours, while the inactivated M. marinum group with inactivated M. marinum suspensions for 12 hours. Cell morphology was observed through microscopy, and cell length was measured. Cell lysates collected from both groups were subjected to liquid chromatography-tandem mass spectrometry analysis to detect energy and oxylipin metabolites. A t-test was utilized to compare the lengths of macrophages between the two groups, while principal component analysis and orthogonal partial least squares-discriminant analysis were conducted to identify differential metabolites. Results:Under the microscope, macrophages in the active M. marinum group formed more granuloma-like cell aggregates compared with those in the inactivated M. marinum group; the macrophages were significantly thinner and longer in the inactivated M. marinum group (439.52 ± 91.67 μm) than in the active M. marinum group (289.96 ± 70.11 μm, P < 0.001). Principal component analysis and orthogonal partial least squares-discriminant analysis of energy metabolism and oxylipin metabolism in macrophages demonstrated good separation between the two groups. As for the energy metabolism, a total of 12 differential metabolites were identified, with the amino acid metabolism showing the most significant changes. Specifically, there was a significant increase in the content of L-citrulline, while the content of L-leucine and serine decreased. As for the oxylipin metabolism, 20 differential metabolites were identified, with the arachidonic acid metabolism showing the most significant changes. Conclusions:Macrophages stimulated by live M. marinum exhibited altered amino acid metabolism and arachidonic acid metabolism compared with those stimulated by inactivated M. marinum, characterized by an increase in L-citrulline content, a decrease in L-leucine and serine levels, and alterations in arachidonic acid content.
