Objective: To explore the relationship between non suicidal self injury (NSSI) behavior and serum lipid levels as well as thyroid function among college students with depression. Methods: A total of 169 college students with depression in the psychiatry departments of tertiary hospitals (grade 3A and 3B) in Ningbo from December 2023 to April 2025 were selected. The Adolescent Self injury Scale (ASIS) was used to assess the presence of NSSI, and participants were accordingly divided into a NSSI group ( n =51) and a non NSSI group ( n =118). General demographic data (including gender, age, and family situation) were collected from both groups. Blood tests were performed to measure lipid profiles [triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C)] and thyroid hormones [triiodothyronine (T3), thyroxine (T4), free triiodothyronine (FT3), free thyroxine (FT4), thyroid stimulating hormone (TSH)]. Multivariate Logistic regression was employed to analyze risk factors for NSSI, and receiver operating characteristic (ROC) curve analysis was used to evaluate the predictive value of serum lipid and thyroid hormone levels for NSSI occurrence in college students with depression. Results: The levels of TC, LDL-C, and TSH in the NSSI group were (4.02±0.73) mmol/L, (2.32±0.36) mmol/L, and (6.57±1.95) mU/L , which were significantly higher than those in the non NSSI group [(3.41±0.56) mmol/L, (2.00±0.27) mmol/L, and ( 4.48± 1.09) mU/L, respectively] ( t =5.32, 5.60, 7.20, all P <0.05). Logistic regression analysis revealed that college students from single parent/reconstituted families, those who had experienced school bullying, and those with higher levels of TC, LDL-C, and TSH had a significantly increased risk of engaging in NSSI ( OR =5.22, 6.12, 5.90, 83.64, 3.64, all P <0.05). ROC curve analysis demonstrated that the combined detection of TC, LDL-C, and TSH had high diagnostic efficacy for predicting NSSI in college students with depression, with a sensitivity of 86.3% and a specificity of 94.9%. Conclusions NSSI behavior in college students with depression is associated with serum lipid levels and thyroid function. These biomarkers may serve as useful reference indicators for assessing the conditions of these patients.

Background and purpose:With the progressive development of breast cancer surgery toward more individualized and minimally invasive approaches,sentinel lymph node biopsy(SLNB)has replaced axillary lymph node dissection(ALND)as the standard method for axillary management in certain early-stage breast cancer patients.However,there is ongoing debate in clinical practice regarding whether regional lymph node irradiation(RNI)is necessary for patients with sentinel lymph node(SLN)positive status who have not undergone ALND.This study aimed to analyze the clinicopathological features and survival prognosis of patients with SLN-positive status who did not undergo ALND,evaluate the clinical application value of RNI,and provide evidence to support clinical treatment decisions for this group of patients.Methods:This single-center retrospective study screened breast cancer patients who underwent SLNB at Shandong Cancer Hospital from September 1,2014,to August 31,2023.All patients signed informed consent for treatment.Based on whether postoperative radiotherapy included regional lymph node irradiation(internal mammary and/or axillary and/or supra-/infra-clavicular fields),patients were divided into the RNI group and the no-RNI group for follow-up.Additionally,patients were further divided into multiple subgroups based on factors such as the type of breast surgery,tumor molecular subtype,and histological grade,to compare the clinical value of RNI among subgroups.The primary endpoint was locoregional recurrence-free survival(LRRFS),and the secondary endpoints included invasive disease-free survival(iDFS)and overall survival(OS).The Strengthening the Reporting of Observational Studies in Epidemiology(STROBE)checklist was followed for this study.Results:Clinical data of 8 328 breast cancer patients'were screened for this study,and after applying inclusion and exclusion criteria,356 patients were included in the analysis,with 186 in the RNI group and 170 in the no-RNI group.There were no significant differences between the two groups in terms of age,body mass index(BMI),menopausal status,tumor location,pathological type,histological grade,vascular invasion,estrogen receptor(ER)and progesterone receptor(PR)status,and human epidermal growth factor receptor 2(HER-2)expression(P＞0.05).However,the number of positive SLNs,T stage,and the proportion of patients undergoing total mastectomy(TM)were significantly higher in the RNI group than in the no-RNI group(P=0.006,P=0.043,P＜0.001).After a median follow-up of 38 months,no recurrence or metastasis was observed in the RNI group,while the recurrence and metastasis rate in the no-RNI group was 3.5%(6/170).Of these,4 cases had local regional recurrence,and 2 had distant metastasis.The RNI group showed superior iDFS compared to the no-RNI group(P=0.017),however there was no statistically significant difference in LRRFS and OS(P=0.051 and P=0.356).Exploratory subgroup analysis indicated that patients with tumor diameter＞2 cm(P=0.033)and triple-negative molecular(TNBC)(P=0.020)might benefit from RNI treatment in terms of LRRFS.Conclusion:For certain high-risk patients,such as those with larger tumor diameter,TNBC,or high non-SLN metastatic risk,RNI still plays an important role in reducing the risk of recurrence and metastasis in breast cancer.In clinical practice,an individualized RNI strategy should be developed based on the patient's residual lymph node tumor load,biological behavior of the tumor,and surgical method.

Background and purpose:Internal mammary sentinel lymph node biopsy(IMSLNB)is a minimally invasive diagnostic technique for regional lymph nodes in breast cancer,which can provide accurate lymph staging and guide adjuvant treatment decision,but its clinical application has been controversial.The purpose of this study was to investigate the prognosis of IMSLNB in early breast cancer.Methods:In this study,a retrospective cohort of 7 949 patients with breast cancer from January 1,2016 to December 31,2021 was analyzed.After applying propensity score matching,the patients were divided into IMSLNB group and no-IMSLNB group,and the regional recurrence-free survival(RRFS),local recurrence-free survival(LRFS),distant metastasis-free survival(DMFS),disease-free survival(DFS)and overall survival(OS)of the two groups were compared.This study was approved by the Clinical Research Ethics Committee of the Affiliated Tumor Hospital of Shandong First Medical University(approval number:SDTHEC20130324).Results:A total of 990 patients were included in the final analysis(330 in the IMSLNB group and 660 in the no-IMSLNB group).IMSLN metastasis was found in 54 patients in the IMSLNB group,including 47 patients with axillary lymph node(ALN)metastasis and 7 patients with IMSLN metastasis only.The IMSLN transfer rate was 16.4%.The median follow-up of 41 months showed that the IMSLNB group demonstrated better 3-year DFS[98.4%vs 94.2%,hazard ratio(HR)=0.509;95%CI:0.312-0.828,P=0.007]and 5-year DFS(92.5%vs 87.3%,HR=0.214,95%CI:0.206-0.222,P=0.011)compared with no-IMSLNB group.However,no significant differences were observed in 3-year OS(99.1%vs 99.4%,HR=0.618,95%CI:0.231-1.655,P=0.338)or 5-year OS(98.5%vs 99.1%,HR=0.52,95%CI:0.51-0.53,P=0.392)between the two groups.The 3-year RRFS in the IMSLNB group was better compared with the no-IMSLNB group(99.09%vs 97.73%,HR=0.066;95%CI:0.061-0.071,P=0.048),while no significant differences were observed in 3-year LRFS(99.70%vs 98.19%,HR=0.209;95%CI:0.201-0.217,P=0.130)or DMFS(95.76%vs 96.06%,HR=0.865,95%CI:0.858-0.872,P=0.820)between the two groups.The exploratory subgroup analysis of DFS revealed that patients in the following subgroups could significantly benefit from IM-SLNB(P＜0.05):diagnosis age(≤50 years),premenopausal status,BMI(≤24),lymphovascular invasion(LVI,present),tumor location(lateral),molecular subtype[hormone receptor positive(HR+)/human epidermal growth factor receptor 2 negative(HER2-)],histological type(invasive ductal carcinoma),and axillary lymph node status(positive).Conclusion:IMSLNB can provide more accurate regional lymph node staging for early breast cancer,help optimize adjuvant radiotherapy strategies,and improve patients'DFS and RRFS.It can be promoted as a minimally invasive staging technique for regional lymph nodes.

Objective:To compare the efficacy of body posture combined with pharmacotherapy and pharmacotherapy alone in the treatment of chronic subdural hematoma(CSDH).Methods:Firstly, retrospective case series study was conducted. Thirty cases of CSDH that had received body posture combined with pharmacotherapy at Department of Neurosurgery, Huashan Hospital Affiliated to Fudan University from December 2016 to October 2020 were studied retrospectively. Twenty-seven patients were male, and 3 patients were female. The age of patients ( M(IQR)) was 66(16) years (range:28 to 84). Nineteen patients had unilateral hematoma, and 11 patients had bilateral hematoma. All patients received pharmacotherapy and body posture therapy that was to raise their lower limbs 20 to 30 cm with leg lift pad and get abdominal compressed with customized abdominal belt in supine position. Patients were required to maintain the body posture as much as possible, with the maximum to 16 to 18 hours per day. Patients with unilateral hematoma should tilt the head to the affected side and avoid tilting it to the opposite side. For patients with bilateral hematoma, there was no need for head lateralization. Patient were treated with oral dexamethasone and atorvastatin simultaneously. The preliminary efficacy of body posture combined with pharmacotherapy was determined by hematoma improvement rate which was analyzed by Clopper-Pearson method. Then, the multi-center, prospective, randomized controlled trial had carried out in 9 medical centers from August 2020 to November 2021. The stratified block randomization method was adopted. Patients were randomized in a ratio of 1∶1 to either receive pharmacotherapy alone(the control group) or body posture combined with pharmacotherapy(the experiment group) for 3 months and followed up for 6 months. Effective treatment was defined as complete absorption of hematoma, or the hematoma volume decreased by more than 10 ml and Markwalder grading scale score had improved by more than 1 point compared to the baseline. The efficacy rate and surgery conversion rate at 3 months and recurrence at 6 months were observed. Comparison between groups was performed with paired sample t test, Mann-Whitney U test, χ2 test, corrected χ2 test, or Fisher exact probability method. Logistic regression was used to compare the effective rate and operation rate between the two groups. Results:In the respective study, 30 patients completed follow-up 13 to 353 days after treatment. At the last follow-up, the incidence of almost complete absorption or significantly absorption of hematoma (hematoma volume was significantly reduced accompanied by symptom improvement) was 93.3%. The 95% CI for the incidence that analyzed by the Clopper-Pearson method was 77.9% to 99.2%. One hundred and six patients were enrolled in the multicenter study. Fifty-five patients underwent body posture combined with pharmacotherapy. The age was 74(17) years (range:26 to 92). Thirty-nine patients were males and 16 were females. Fifty-one patients underwent pharmacotherapy alone. The age was 69(12) years (range:48 to 84). Thirty-seven patients were males and 14 were females. The length of body posture recorded in diary card was (15.7±2.3) hours(range:7.6 to 19.3 hours). The efficacy rate in the body posture combined with pharmacotherapy group and pharmacotherapy alone group were 83.6% (46/55) and 56.9% (29/51), respectively at 3 months. The result of the logistic regression analysis showed that the efficacy of body posture combined with pharmacotherapy group was better than that of pharmacotherapy alone group ( OR=3.88,95% CI:1.57 to 9.58, P=0.003). Surgery rate in the body posture combined with pharmacotherapy group and pharmacotherapy alone group were 5.5% (3/55) and 21.6% (11/51) respectively. The result of Logistic regression showed that the pharmacotherapy alone group was more likely to be converted to surgery ( OR=0.21,95% CI:0.05 to 0.80, P=0.023). At the 6 months, no recurrence of cases was found in the body posture combined with pharmacotherapy group. However, the recurrence rate of pharmacotherapy alone group was 6.3% (3/48), there was no significant difference between the two groups ( P>0.05). Conclusion:The effect of body posture combined with pharmacotherapy for chronic subdural hematoma is better than that of pharmacotherapy alone.

Objective:To explore the changes of brain excitation/inhibition balance and gray matter volume (GMV) and their correlations with clinical features in benign childhood epilepsy with centrotemporal spikes (BECTS).Methods:A cross-sectional study was performed; 83 BECTS children enrolled from Department of Diagnostic Radiology, Jinling Hospital, Affiliated Hospital of Medical School, Nanjing University from January 2015 to January 2024 were selected as BECTS group. During the same period, 101 age- and gender-matched healthy children were recruited as healthy control group through advertisements in local primary schools. Data of conventional MRI and resting-state functional MRI (rs-fMRI) of the two groups were collected. Whole brain GMV was analyzed by voxel-based morphometry (VBM), and Hurst index was calculated based on time series data of blood oxygen level dependent (BOLD) signal of rs-fMRI. Correlations of GMV and Hurst index with disease duration and onset age in children with BECTS were explored by Pearson correlation analysis.Results:Compared with the healthy control group, the BECTS group had significantly increased GMV and decreased Hurst index in the bilateral Rolandic region ( P<0.05). Pearson correlation analysis showed that in the BECTS group, GMV in bilateral Rolandic region was negatively correlated with onset age ( r=-0.267, P=0.015) and positively correlated with disease course ( r=0.267, P=0.015); Hurst index in bilateral Rolandic region was positively correlated with onset age ( r=0.323, P=0.003) and negatively correlated with disease course ( r=-0.240, P=0.029); Hurst index was negatively correlated with GMV in bilateral Rolandic region ( r=-0.328, P=0.003). Conclusion:BECTS children have excitation/inhibition imbalance in epilepsy-related regions and cortical structural delay, and both of them are related to onset age and disease course.

Objective:To investigate the differences of the glymphatic system (GS) function between patients with mesial temporal lobe epilepsy with hippocampal sclerosis (mTLE-HS) and healthy controls and between different seizure types by using diffusion tensor imaging along perivascular space (DTI-ALPS), and to analyze the correlation between GS function and the course of disease, as well as the efficacy of predicting the surgical outcome.Methods:This study was a cross-sectional study. A total of 171 patients with mTLE-HS (mTLE-HS group) and 75 healthy volunteers (HC group) were retrospectively enrolled from July 2009 to July 2021 at Jinling Hospital, Affiliated Hospital of Medical School, Nanjing University. The general information of all subjects, such as seizure type (partial seizure, secondary generalized seizure), surgical outcome, etc., was analyzed. The 3D magnetization prepared rapid gradient echo T 1WI and DTI sequence images were collected. The VBM analysis method was used to segment cerebrospinal fluid and calculate the volume. The ALPS index of the bilateral brain was calculated using the Atlas-based DTI-ALPS method. Independent sample t-test or paired t test were used to compare the ALPS index between the mTLE-HS group and HC group, and between patients with different seizure types. Pearson correlation analysis was used to analyze the correlation between bilateral ALPS index and disease duration in mTLE-HS group. The predictive value of the ALPS index for surgical outcomes was evaluated by receiver operating characteristics curve and area under the curve. Results:Among the 171 mTLE-HS patients, 98 patients were mTLE with left-side HS (mTLE-LHS) and 73 patients were mTLE with right-side HS (mTLE-RHS); 37 patients underwent surgical treatment, including 27 with good prognosis and 10 with poor prognosis. Compared with the HC group, the left-side ALPS index of mTLE-LHS and mTLE-RHS were both decreased ( P<0.05). The right-side ALPS index in mTLE-RHS was lower than that in the HC group ( P<0.001). There was no significant difference in the right-side ALPS index between mTLE-LHS and HC group ( P=0.080). The ALPS index on the affected side of patients with secondary generalized seizures was significantly lower than that of patients with only partial seizures (all P<0.05), but the difference in ALPS index on the healthy side was not statistically significant( P>0.05). The left-side and right-side ALPS index in mTLE-LHS were negatively correlated with disease duration ( r=-0.272, P=0.007; r=-0.307, P=0.002), but no significant correlation was found between the left-side or right-side ALPS index in mTLE-RHS (all P>0.05). The DTI-ALPS index on the affected side in mTLE-HS patients exhibited good diagnostic accuracy for surgical outcome classification, with an area under the curve of 0.778. Conclusions:The patients with mTLE-HS exhibit dysfunction of the GS, and the degree of impairment is related to the type of seizure and the course of epilepsy. The ALPS index, which characterizes the function of GS, demonstrates good diagnostic accuracy for classifying surgical outcomes.

Objective:To evaluate the topological alterations of resting-state brain networks in patients with idiopathic generalized epilepsy with generalized tonic-clonic seizure (IGE-GTCS) using minimum spanning tree (MST) based on graph theoretic analysis, and to further analyze the relationships between topological features, duration, and antiepileptic drug response.Methods:This study was a cross-sectional study. Retrospectively, 75 IGE-GTCS patients and 37 healthy controls (HC) who underwent brain MR imaging at the Affiliated of Nanjing University Medical School Drum Tower Hospital from January 2013 to December 2020 were enrolled. IGE-GTCS patients were grouped into well-controlled subgroup (WC; n=55) and drug-resistant subgroup (DR; n=20) according to their response to antiepileptic drugs. Firstly, the time series correlations between 116 regions of the whole brain of each subject were calculated to construct functional connectivity matrices. For each functional connectivity matrix, the Kruskal algorithm was used to MST, and the topological metrics of each MST were calculated, including leaf fraction, tree hierarchy, and diameter. The comparison of MST topological metrics between the two groups was performed using two-sample t-test. Pearson correlation analysis was used to calculate the correlation between disease duration and MST metrics in the WC subgroup and the DR subgroup. Results:Compared with the HC group, the MST leaf fraction ( t=2.27, P=0.025) increased in the IGE-GTCS patient group, and the diameter decreased ( t=-2.24, P=0.027), there was no statistically significant difference in tree hierarchy between IGE-GTCS patient group and HC group ( t=0.98, P=0.328). The MST leaf fraction ( t=-2.39, P=0.019) and tree hierarchy ( t=-2.24, P=0.027) in the WC subgroup was decreased compared with the DR subgroup, while there was no statistically significant difference in diameter between WC subgroup and DR subgroup ( P=0.093). The correlation analysis showed the MST diameter in WC subgroup was significantly correlated with disease duration ( r=0.452, P<0.001), while the MST diameter in DR subgroup was not significantly correlated with disease duration ( r=-0.062, P=0.847). Conclusions:Patients with IGE-GTCS exhibit specific alterations in the global topology of brain network, characterized by increased centralization and efficiency. The effective antiepileptic drug treatment is associated with a recovery of brain network abnormalities.

Objective:To investigate the effect of peripheral white blood cell(WBC) count on adverse pregnancy outcomes.Methods:A retrospective analysis was conducted on pregnant women who delivered at Minhang Hospital affiliated with Fudan University between January 2013 and June 2020. Demographic data, WBC counts, and diagnostic information on gestational diabetes mellitus(GDM), gestational hypertension, and preeclampsia/eclampsia were extracted from electronic medical records. Logistic regression models were used to evaluate the association between WBC counts in the first(WBC-1) and second trimesters(WBC-2) and metabolically related pregnancy outcomes.Results:A total of 24 143 pregnant women were included, with a mean age of(29.1±4.9) years and a mean pre-pregnancy body mass index(BMI) of(21.1±2.8) kg/m 2. The mean WBC counts in the first and second trimesters were 8.1×10 9/L and 8.9×10 9/L, respectively. The incidence rates of GDM, gestational hypertension, and preeclampsia/eclampsia were 5.6%, 4.8%, and 1.8%, respectively. After adjusting for relevant confounders, a core standard deviation( s) increase in WBC-1 was associated with a 6%, 18%, and 14% increased risk of GDM, gestational hypertension, and preeclampsia/eclampsia, respectively( P<0.001). Similarly, a one s increase in WBC-2 was associated with a 10% increased risk for all three adverse outcomes( P<0.001). Conclusion:Elevated peripheral WBC levels in the first and second trimesters are independently associated with increased risk of adverse pregnancy outcomes, independent of traditional risk factors.

Objective:To determine the epidemiological characteristics of human bocavirus (HBoV) in children with acute respiratory infections (ARI) in Bengbu City, Anhui Province, in 2024.Methods:Nasopharyngeal swab samples were collected from 269 children with ARI in Bengbu City, Anhui Province, in 2024. Seventeen respiratory pathogens were screened using quantitative fluorescence PCR. For HBoV-positive samples, the VP1/VP2 structural gene fragments of HBoV were amplified and sequenced for genetic evolutionary analysis.Results:Among the 269 nasopharyngeal swab samples from children with ARI, the overall detection rate of respiratory pathogens was 48.33% (103/269). The top three pathogens with the highest detection rates were: Influenza A virus (FluA): 10.04% (27/269), Respiratory syncytial virus (RSV): 8.18% (22/269), Human bocavirus (HBoV): 7.43% (20/269). The age distribution of HBoV-infected children showed that the detection rate was highest in the 0-2 years age group (50%, 10/20), followed by the 3-5 years age group (25%, 5/20) and the over 6 years age group (25%, 5/20). However, there was no statistically significant difference in viral detection rates among the age groups. Genetic evolutionary analysis based on VP1/VP2 revealed that all 13 HBoV strains were of the HBoV-1 genotype.Conclusions:HBoV is one of the major pathogens causing ARI in children in Bengbu City, Anhui Province, in 2024, with HBoV-1 being the predominant genotype. Additionally, infants aged 0-2 years are the most susceptible population to HBoV infection.
