Objective: To identify the core symptoms and bridge symptoms in the network structure among adolescents bullying victimization, anxiety and depressive symptoms, and to explore the interrelationships among these three variables, so as to provide a basis for the precise prevention of bullying behaviors and the improvement of adolescents psychological health conditions. Methods: From October to November 2023, a stratified cluster random sampling method was employed to select 4 759 middle and high school students from four cities in Guangxi: Beihai, Guigang, Hechi, and Laibin. The Chinese version of the Olweus Bully/Victim Questionnaire (OBVQ) was used to assess bullying victimization among adolescents, while the Generalized Anxiety Disorder-7 (GAD-7) and the Patient Health Questionnaire-9 (PHQ-9) were utilized to assess anxiety and depressive symptoms, respectively. The Bootnet package (version 1.6) in R software (version 4.4.1) was used to construct a network structure and analyze the associations between bullying victimization, anxiety symptoms and depressive symptoms among adolescents. Results: The reporting rates of depressive symptoms, anxiety symptoms, and bullying victimization among adolescents in Guangxi were 24.67%, 16.33%, and 16.58%, respectively. Network analysis revealed that the node with the highest expected influence was "property being taken or damaged", with a standardized expected influence (EI) index of 2.09. The top two nodes in terms of bridge expected influence were "thoughts of self harm or suicide" and "irritability", with standardized bridge expected influence (BEI) indices of 2.15 and 1.27, respectively. The stronger associations were observed between the node "property being taken or damaged" and the nodes "physical attacks such as hitting, kicking, pushing, or shoving" and "ridiculed due to accent", with edge weights of 0.43 and 0.35, respectively. Conclusion Targeting preventive measures against the symptoms with the highest expected influence and bridge expected influence in the network of bullying victimization, anxiety and depressive symptoms among adolescents may be an effective approach to reduce the negative impact of bullying victimization, anxiety and depressive symptoms on adolescents.

Transarterial radioembolization (TARE) is a widely utilized therapeutic approach for hepatocellular carcinoma (HCC), however, the clinical implementation is constrained by the stringent preparation conditions of radioembolization agents. Herein, we incorporated the superstable homogeneous iodinated formulation technology (SHIFT), simultaneously utilizing an enhanced solvent form in a carbon dioxide supercritical fluid environment, to encapsulate radionuclides (such as ¹³¹I,¹⁷⁷Lu, or ¹⁸F) with lipiodol for the preparation of radiolipiodol. The resulting radiolipiodol exhibited exceptional stability and ultra-high labeling efficiency (≥99%) and displayed notable intratumoral radionuclide retention and in vivo stability more than 2 weeks following locoregional injection in subcutaneous tumors in mice and orthotopic liver tumors in rats and rabbits. Given these encouraging findings, ¹⁸F was authorized as a radiotracer in radiolipiodol for clinical trials in HCC patients, and showed a favorable tumor accumulation, with a tumor-to-liver uptake ratio of ≥50 and minimal radionuclide leakage, confirming the feasibility of SHIFT for TARE applications. In the context of transforming from preclinical to clinical screening, the preparation of radiolipiodol by SHIFT represents an innovative physical strategy for radionuclide encapsulation. Hence, this work offers a reliable and efficient approach for TARE in HCC, showing considerable promise for clinical application (ChiCTR2400087731).

Objective To explore the risk factors related to afterload mismatch(AM)after transcatheter mitral valve repair(MitraClip).Methods This was a retrospective cohort study.48 patients hospitalized in the Department of Cardiovascular Medicine,the First Affiliated Hospital of Sun Yat-sen University from December 2021 to December 2023,who underwent MitraClip due to severe mitral regurgitation(MR)were included.Preoperative clinical data,laboratory tests,and preoperative and postoperative color Doppler echocardiographic examination results of surgical patients were collected.AM was defined as the left ventricular ejection fraction(LVEF)decreased by 15％or more after surgery compared with the one before(dLVEF≤-15％).Patients were divided into AM group and non-AM group according to whether afterload mismatch occurred.Univariate and multivariate logistic regression were used to analyze the risk factors of postoperative AM.Results Among 48 patients who underwent MitraClip,14 of them(29.2％)developed afterload-mismatched.For those without AM,their overall LVEF was improved after the operation;for patients in both AM group and non-AM group,their overall left ventricular end-diastolic diameter(LVEDd),left ventricular end-diastolic diameter volume index(LVEDVi)was reduced compared with the preoperative ones.Univariate regression analysis showed that C-reactive protein levels(OR 1.98,95％CI 1.02-3.83),platelets(OR 2.22,95％CI 1.08-4.53),systemic immune inflammation index(OR 1.96,95％CI 1.03-3.71)were associated with an increased risk of AM in patients undergoing MitraClip(all P＜0.05),while those with larger right atrial diameter(OR 0.35,95％CI 0.13-0.93)or moderate to severe tricuspid regurgitation(OR 0.19,95％CI 0.05-0.81)were less likely to develop into AM(both P＜0.05),which is still satisfied after adjustment.Conclusions For patients who underwent MitraClip,C-reactive protein levels,platelets and systemic immune inflammation index(SII)are associated with an increased risk of afterload mismatched,while those with larger right atrial diameter or moderate to severe tricuspid regurgitation were less likely to develop into AM.

Objective:To investigate possible mechanism on protien LMP1 expressed by EBV inducing plasmablast differentiation of DLBCL cell via the mTORC1 pathway.Methods:The expression levels of LMP1 protein,CD38 and the phosphorylation levels of p70S6K in EBV+and EBV-DLBCL cell lines were detected by Western blot.Cell lines overexpressing LMP1 gene stablely were constructed and LMP1 gene was silenced by RNAi.The expression of LMP1 gene was verified by RT-qPCR.The expression levels of LMP1 and CD38 and the phosphorylation levels of p70S6K in each group were detected by Western blot.Results:Compared with EBV-DLBCL cells,the expression of LMP1 was detected on EBV+DLBCL cells(P=0.0008),EBV+DLBCL cells had higher phosphorylation levels of p70S6K(P=0.0072)and expression levels of CD38(P=0.0091).Compared with vector group,the cells of LMP1OE group had higher expression levels of LMP1 and CD38(P=0.0353;P＜0.0001),meanwhile molecular p70S6K was phosphorylated much more(P=0.0065);expression of LMP1 mRNA was verified(P＜0.0001).Compared with si-NC group,expression level of LMP1 protein(P=0.0129)was not detected and phosphorylated p70S6K disappeared of LMP1KO group(P=0.0228);meanwhile,expression of CD38 decreased,although there was no significant difference(P=0.2377).Conclusion:LMP1 promotes DLBCL cells plasmablast differentiation via activating mTORC1 signal pathway.

Objective:To evaluate the clinical efficacy of modified anterior subacromial approach plate internal fixation for three- or four-part valgus impacted proximal humeral fractures.Methods:A retrospective analysis of 35 patients treated between November 2018 and November 2021 at Fuzhou Second General Hospital was performed, including 15 males and 20 females aged 61.7±7.8 years (range: 40 to 73 years). Patients were classified under the Neer system; 17 had 3-part fractures and 18 had 4-part fractures. The modified approach accessed the fracture site via the natural interval of the deltoid anterior bundle, facilitating fracture reduction and fixation using a plate. Operative time, incision length, intraoperative fluoroscopy time, follow-up duration, Constant-Murley score, fracture healing time, visual analogue scale (VAS) for pain, and humeral neck-shaft angle were assessed. Intraoperative and postoperative complications were also recorded.Results:All patients underwent successful surgery, with an average incision length of 8.1±0.3 cm (range, 7.6-9.0 cm) and intraoperative fluoroscopy time of 6.6±0.3 seconds (3-part fractures: 6.3±0.2 s, 4-part fractures: 6.8±0.2 s, t=6.350, P<0.001). Follow-up averaged 22.1±5.8 months (range, 14-31 months). Fracture healing occurred in 11.8±1.4 weeks (range, 10-15 weeks). At the final assessment, the VAS score was 1.6±0.7 (range, 1-3), the Constant-Murley score was 89.6±2.9 (range, 84-95), and the humeral neck-shaft angle was 133.4°±3.1° (range, 128°-138°; 3-part fractures: 133.6°±3.5°, 4-part fractures: 133.3°±2.8°, t=0.288, P=0.075). No complications such as avascular necrosis of the humeral head, varus collapse of the fracture site, or axillary nerve injury were recorded. Conclusion:The modified anterior subacromial approach plate internal fixation is a minimally invasive, safe, and effective treatment for valgus impacted three- and four-part proximal humeral fractures, demonstrated by excellent surgical outcomes and absence of major complications.

Objective:To investigate the clinical manifestations, serological and cerebrospinal fluid test results for syphilis, imaging features, and prognoses of cerebral syphilitic gumma.Methods:The clinical data of 1 patient with cerebral syphilitic gumma admitted to Department of Neurology, Second Affiliated Hospital of Soochow University in March 2023 were retrospectively analyzed. Papers about cerebral syphilitic gumma were searched from journals in Journal Citation Reports Q1 from 2000 to 2019, journals from 2020 to 2024 in PubMed, WOS, Embase, and Scopus databases, and journals from 2000 to 2024 in Wanfang Database, CNKI, and VIP database; the clinical data of 54 patients with cerebral syphilitic gumma reported in above databases and 1 patient in our hospital were collected for pooled analysis.Results:The main clinical manifestations of 55 cerebral syphilitic gumma patients included headache (32, 58.2%), lateral limb/facial weakness (25, 45.5%), nausea and vomiting (14, 25.5%), dizziness (11, 20.0%), sensory disturbances (10, 18.2%), blurred vision (7, 12.7%), seizure (5, 9.1%)), hearing loss (5, 9.1%), tinnitus (5, 9.1%), memory loss (3, 5.5%), aphasia (3, 5.5%), dysarthria (2, 3.6%), drop attack (2, 3.6%), weakness in opening eyes (2, 3.6%), unresponsiveness (1, 1.8%), Argyll-Robertson pupil (1, 1.8%), tabes dorsalis gait (1, 1.8%), and fever (1, 1.8%). In 51 patients who reported complete serologic test results, 45 patients (88.2%) were positive for non-specific antibodies to syphilis, and all patients were positive for specific antibodies to syphilis. In 34 patients underwent cerebrospinal fluid examination, 25 (73.5%) were positive for non-specific antibodies to syphilis, and 32 (94.1%) were positive for specific antibodies to syphilis. Isolated intracranial lesion (43, 78.2%) was mostly common in imaging test, and the frequently involved cranial sites were, orderly, the frontal lobe (14, 25.5%), parietal lobe (14, 25.5%), temporal lobe (5, 9.1%), frontotemporal lobe (3, 5.5%), frontoparietal lobe (2, 3.6%), parieto-occipital lobe (2, 3.6%), nucleus pulposus (1, 1.8%), clivus (1/55, 1.8%), and cerebral peduncle of the midbrain (1, 1.8%). Thirty patients (54.5%) were misdiagnosed as having other intracranial space-occupied diseases, orderly, glioma (11, 36.7%), metastatic tumors (5, 16.7%), meningiomas (4, 13.3%), other unexplained intracranial space-occupying (4, 13.3%), brain abscess (3, 10.0%), cavernous hemangioma (1, 3.3%), intracranial lymphoma (1, 3.3%), auditory nerve and pituitary tumors (1, 3.3%). Of the 42 patients who reported prognosis after anti-syphilitic treatments, 41 had varying degrees of improvement, and one died of brain herniation.Conclusion:Because of atypical clinical manifestations and lack of clear diagnostic criteria, cerebral syphilitic gumma is often misdiagnosed as intracranial tumors; cerebral syphilitic gumma should be considered in patients with positive non-specific antibodies to syphilis/specific antibodies to syphilis in serum and cerebrospinal fluid having neurological symptoms and intracranial space-occupied foci; timely diagnosed and treated patients can prognosed well.

Background::Studies suggest seasonal fluctuations of symptoms in Parkinson’s disease (PD) patients in Western countries. However, the association between seasonal change and variation in nonmotor symptoms (NMS) in Chinese PD patients is unclear. Here, we studied whether there is a change rule with annual cycle with severity of NMS for patients with PD in Southeast China.Methods::We studied 1005 PD patients between April 2008 and October 2020. Patients were classified into four seasons according to the 24 Chinese solar terms, based on assessment date. We compared comprehensive NMS scales and polysomnography parameters among groups and conducted further analysis of disease severity.Results::Among the 1005 patients studied, the mean age was 64.2 ± 9.7 years and 569 (56.6%) of them were men. Relative to the summer group, patients assessed during winter had higher Scales for Outcomes in Parkinson’s disease-Autonomic Dysfunction (SCOPA-AUT) scores ( P = 0.045). The sleep efficiency factor scores of Pittsburgh Sleep Quality Index in patients were higher during spring than summer ( P = 0.009). Among patients who completed polysomnography during the same period ( n = 135), compared with summer follow-ups, we observed a higher percentage of NREMS1 in winter and spring follow-ups ( P = 0.042, P = 0.011), a higher NREMS1 time in spring follow-ups ( P = 0.0024), a lower NREMS2 time in winter follow-ups ( P = 0.007), and a higher percentage of phasic rapid eye movement (REM)-sleep without atonia in autumn and winter follow-ups ( P = 0.026 and P = 0.020, respectively). In a subset of patients with PD and REM sleep behavior disorder (RBD; n = 182), those visited during winter had higher scores for RBD questionnaire-Hong Kong and its factor 1 (dream-related sub-score) than those visited during summer ( P = 0.034, P = 0.020). We observed similar findings for SCOPA-AUT and sleep efficiency factor scores in early stage patients in subgroup analysis. Conclusions::PD patients assessed for follow-up during summer showed less severe symptoms of autonomic dysfunction and RBD symptoms than those assessed in winter, and less sleep disturbance than those in spring and winter, suggesting that seasonal change and NMS fluctuation are related, especially in patients with early stage PD.

Objective:To understand the identification value of pointing gestures in children with autism spectrum disorder(ASD) and its relationship with functional development.Methods:From December 2020 to November 2021, 1 099 children from Children’s Health Care Center of Beijing Children’s Hospital were tested by pointing gestures test, including 942 ASD children and 157 typical developed children.And the data of children's neuropsychological development scale from 800 children aged 1.0-5.9 were collected.SPSS 20.0 was used for statistical analysis. Trend test was used to analyze the distribution of pointing gestures test sensitivity in autistic children, and ANOVA was used to analyze the relationship between pointing gestures test scores and functional development fields.Results:The sensitivity of pointing gestures was 83.5% in children aged 1.0-10.0 years, 76.3%-93.1% in children aged 1.0-4.9 years, and 93.1%-95.1% in children aged 1.0-2.9.With the increase of age, the sensitivity of pointing gestures in autistic children (linear-by-linear association =164.889, P<0.001) and the Yoden index had a decreasing trend. The positive predictive value (91.53%-100.00%) and negative predictive value (75.36%-91.84%) were found in the children aged 1.0-10.0 years.The sensitivity of pointing gestures test was 44.9% in children with mild autism aged 1.0-10.0 years and 46.5%-65.9% in children with mild autism aged from 1.0-3.9 years. The sensitivity of pointing gestures test was 81.5% in children with moderate autism aged from 1.0-10.0 years and 87.3%-97.8% in children with moderate autism aged 1.0-3.9 years. The sensitivity of the pointing gestures test was 97.2% in children with severe autism aged 1.0-10.0 years, and 100.0% in children with severe autism aged 1.0-3.9 years. The sensitivity of the pointing gestures in mild, moderate and severe autism children decreased with age (linear-by-linear association values were 16.725, 64.232, 66.732 respectively, all P<0.001). The children with severe autism mainly scored 2 points (80.3%, 419/522) on the pointing gestures test , and children with moderate autism mainly scored 1 point(64.2%, 170/265) on the pointing gestures test. There were significant differences in functional development among different pointing gestures test groups.Functional development score in the autism children with 0 score of pointing gestures test was significantly higher than those with 1 score and 2 scores of pointing gestures test (all P<0.05). Conclusion:Pointing gestures has good sensitivity in children with autism (especially 1.0-4.9 years of age), and may serve as an objectively observable screening method. The better children with autism score on the pointing gestures, the better their functional development.

Objective To analyze the genetic subtypes of human immunodeficiency virus (HIV) and the prevalence of pretreatment drug resistance in the newly reported HIV-infected men in Guangxi. Methods The stratified random sampling method was employed to select the newly reported HIV-infected men aged≥50 years old in 14 cities of Guangxi from January to June in 2020.The pol gene of HIV-1 was amplified by nested reverse transcription polymerase chain reaction and then sequenced.The mutation sites associated with drug resistance and the degree of drug resistance were then analyzed. Results A total of 615 HIV-infected men were included in the study.The genetic subtypes of CRF01_AE,CRF07_BC,and CRF08_BC accounted for 57.4% (353/615),17.1% (105/615),and 22.4% (138/615),respectively.The mutations associated with the resistance to nucleoside reverse transcriptase inhibitors (NRTI),non-nucleoside reverse transcriptase inhibitors (NNRTI),and protease inhibitors occurred in 8 (1.3%),18 (2.9%),and 0 patients,respectively.M184V (0.7%) and K103N (1.8%) were the mutations with the highest occurrence rates for the resistance to NRTIs and NNRTIs,respectively.Twenty-two (3.6%) patients were resistant to at least one type of inhibitors.Specifically,4 (0.7%),14 (2.3%),4 (0.7%),and 0 patients were resistant to NRTIs,NNRTIs,both NRTIs and NNRTIs,and protease inhibitors,respectively.The pretreatment resistance to NNRTIs had much higher frequency than that to NRTIs (2.9% vs.1.3%;χ²=3.929,P=0.047).The prevalence of pretreatment resistance to lamivudine,zidovudine,tenofovir,abacavir,rilpivirine,efavirenz,nevirapine,and lopinavir/ritonavir was 0.8%, 0.3%, 0.7%, 1.0%, 1.3%, 2.8%, 2.9%, and 0, respectively. Conclusions CRF01_AE,CRF07_BC,and CRF08_BC are the three major strains of HIV-infected men≥50 years old newly reported in Guangxi,2020,and the pretreatment drug resistance demonstrates low prevalence.

To develop a caregiver parenting behavior scale for children aged 2 to 6 years, and to verify its reliability and validity. This study recruited 1 350 caregivers of children aged 2 to 6 years. The item discrimination analysis and exploratory factor analysis were used to analyze the structure, dimensions and items of the scale. Homogeneity reliability, split-half reliability and test-retest reliability were used to analyze the reliability of the scale. Content validity and construct validity were used to analyze the validity of the scale. The results showed that the final scale contained 7 dimensions and 45 items. Cronbach's α coefficient of the total scale was 0.945; the coefficient of split half was 0.899; the test-retest reliability analysis showed that the correlation coefficients between the two tests were 0.893 (total score), 0.854 (social), 0.832 (language), 0.871 (gross motor), 0.893 (fine motor), 0.862 (cognitive), 0.832 (self-care), and 0.872 (sensory). The content validity analysis was carried out by two rounds of expert argumentation using Delphi expert consultation method. The Kendall coefficient of the items score in two rounds of Delphi expert consultation was 0.813 (P<0.01). The structure validity analysis showed that there were significant correlations between each dimension and the total scale, also between each dimension of the scale, and the extracted average variance values of each dimension was greater than the correlation coefficients between this dimension and other dimensions. In conclusion, the reliability and validity of the scale are qualified. It can be used as a tool to evaluate and guide the parenting behavior of caregivers of children aged 2 to 6 years.
