BackgroundPrevious studies have identified a close relationship among psychological neglect and abuse， negative affect， different stages of adolescence， and suicidal ideation. However， the mechanisms underlying the impact of psychological abuse and neglect on suicidal ideation among left-behind adolescents remain unclear， and this field of research is still in its relative infancy. ObjectiveTo explore the relationship between psychological neglect/abuse and suicidal ideation among left-behind adolescents， as well as the mediating role of negative affect and the moderating effect of different stages of adolescence， so as to provide insights for preventing and intervening suicidal ideation in this population. MethodsFrom November 2021 to May 2022， a cluster random sampling technique was utilized to select 2 309 left-behind adolescents in western China. Assessments were conducted using the Child Psychological Abuse and Neglect Scale （CPANS）， the Positive and Negative Suicide Ideation （PANSI） and the Positive and Negative Affect Schedule for Children （PANAS-C）. Spearman correlation coefficients were calculated across all samples， and Process 4.1 was employed to test the mediating role of negative affect and the moderating role of different stages of adolescence in the pathway linking psychological abuse/neglect to suicidal ideation. ResultsA total of 2 119 left-behind adolescents （mean age： 14.94±1.20 years） completed the study， with males comprising 51.34% （1 088/2 119） and females 48.66% （1 031/2 119）.Among left-behind adolescents， scores on CPANS psychological neglect subscale showed positive correlations with both psychological abuse subscale scores and PANAS-C negative affect subscale scores （r=0.446， 0.496， P<0.01）. Additionally， CPANS psychological neglect and psychological abuse subscale scores were also positively correlated with PANSI scores （r=0.487， 0.508， P<0.01）. Furthermore， PANAS-C negative affect subscale scores demonstrated a positive correlation with PANSI scores （r=0.499， P<0.01）. Negative affect partially mediated the relationship between psychological abuse/psychological neglect and suicidal ideation， with effect sizes of 0.166 （95% CI： 0.141~0.191） and 0.131 （95% CI： 0.112~0.152）. Different stages of adolescence moderated the latter part （negative emotion → suicidal ideation） of the indirect mediation path from psychological neglect to suicidal ideation through negative affect （β=-0.066， P<0.01）. ConclusionBoth psychological neglect and psychological abuse may influence suicidal ideation among left-behind adolescents via negative affect. Moreover， different stages of adolescence may moderate the indirect path from psychological neglect to suicide ideation through negative affect.

Background::While type 2 diabetes mellitus (T2DM) is considered a putative causal risk factor for coronary artery disease (CAD), the intrinsic link underlying T2DM and CAD is not fully understood. We aimed to highlight the importance of integrated care targeting both diseases by investigating the phenotypic and genetic relationships between T2DM and CAD.Methods::We evaluated phenotypic associations using data from the United Kingdom Biobank ( N = 472,050). We investigated genetic relationships by leveraging genomic data conducted in European ancestry for T2DM, with and without adjustment for body mass index (BMI) (T2DM: Ncase/ Ncontrol = 74,124/824,006; T2DM adjusted for BMI [T2DM adjBMI]: Ncase/ Ncontrol = 50,409/523,897) and for CAD ( Ncase/ Ncontrol = 181,522/984,168). We performed additional analyses using genomic data conducted in multiancestry individuals for T2DM ( Ncase/ Ncontrol = 180,834/1,159,055). Results::Observational analysis suggested a bidirectional relationship between T2DM and CAD (T2DM→CAD: hazard ratio [HR] = 2.12, 95% confidence interval [CI]: 2.01–2.24; CAD→T2DM: HR = 1.72, 95% CI: 1.63–1.81). A positive overall genetic correlation between T2DM and CAD was observed ( rg = 0.39, P = 1.43 × 10 -75), which was largely independent of BMI (T2DM adjBMI–CAD: rg = 0.31, P = 1.20 × 10 –36). This was corroborated by six local signals, among which 9p21.3 showed the strongest genetic correlation. Cross-trait meta-analysis replicated 101 previously reported loci and discovered six novel pleiotropic loci. Mendelian randomization analysis supported a bidirectional causal relationship (T2DM→CAD: odds ratio [OR] = 1.13, 95% CI: 1.11-1.16; CAD→T2DM: OR = 1.12, 95% CI: 1.07-1.18), which was confirmed in multiancestry individuals (T2DM→CAD: OR = 1.13, 95% CI: 1.10-1.16; CAD→T2DM: OR = 1.08, 95% CI: 1.04-1.13). This bidirectional relationship was significantly mediated by systolic blood pressure and intake of 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors, with mediation proportions of 54.1% (95% CI: 24.9-83.4%) and 90.4% (95% CI: 29.3-151.5%), respectively. Conclusion::Our observational and genetic analyses demonstrated an intrinsic bidirectional relationship between T2DM and CAD and clarified the biological mechanisms underlying this relationship.

Objective:To conduct a multidimensional quantification and analysis of the development trajectory of both "quality" and "quantity" in China's higher education from 2001 to 2021, and lay a solid foundation for the construction of a high-quality education system.Methods:Based on macro statistical data on education in China from 2001 to 2021, a comprehensive indicator system for the development level of higher education was established. This system included six dimensions: educational conditions, financial support, institutional safeguards, scientific research, social services, and international collaboration. Methods such as entropy-weighted TOPSIS, general difference index, spatial autocorrelation, and hot spot analysis were used to evaluate the level of high-quality development of higher education and its spatial differentiation. Additionally, an obstacle degree analysis model was used to evaluate the factors hindering the high-quality development of higher education.Results:The high-quality development level of China's higher education has steadily improved, with a growth rate of 2.85%. The spatial distribution exhibited a clustering pattern, with stable hotspot regions established in the eastern region characterized by significant "spillover" effects. Concurrently, the western regions narrowed the development gap compared with other areas. Scientific research represents the primary challenge to achieving high-quality development in higher education, with an average obstacle degree of 18.46%. Books per student, fixed assets per student, foreign technology imported per institution, research & development project funds, research & development projects per institution, and personnel investment in research & development projects were important constraints on the development of higher education in China and the provinces.Conclusions:Resource sharing and linkage need to be guaranteed by policy and institutional support, and each subject of higher education should give full play to its own advantages to contribute to the high-quality development of higher education through interregional linkage development, mutual synergy, and common progress.

Objective To explore the effects of motor acupuncture based on movement pattern adjustment theory on Oswestry Disability Index (ODI), modified Japanese Orthopedic Association (JOA) score and the prognosis in patients with non-specific low back pain (NLBP). Methods A total of 98 patients with NLBP who were admitted to the hospital from March 2020 to March 2023 were randomly divided into control group and observation group, with 49 patients in each group. The control group received lumbar and pelvic rhythm training, while the observation group received motor acupuncture based on movement pattern adjustment theory. The Visual Analogue Scale (VAS) score, ODI score, JOA score, low back electromyographic signals[the ratio of maximum EMG during extension to maximum EMG during maximum voluntary flexion (EXT/MVF) and the ratio of maximum EMG during flexion to maximum EMG during maximum voluntary flexion (FLEX/MVF)], and serum inflammatory factors[interleukin-6 (IL-6), interleukin-1β (IL-1β) and tumor necrosis factor-α] in both groups were observed before and after treatment. Clinical efficacy and 3-month recurrence rate were compared between the two groups. Results After 2 weeks of treatment, VAS score and ODI score of the observation group were lower than those of the control group, and JOA score was higher than that of the control group (P < 0.05). EXT/MVF and FLEX/MVF of the erector spinae and multifidus muscle in the observation group were higher than those in the control group (P < 0.05). Serum IL-6, IL-1 β and TNF-α levels two weeks after treatment in the observation group were lower than those in the control group(P < 0.05). The effective rate of the observation group was higher, and 3-month recurrence rate of the observation group was lower than that of the control group (P < 0.05). Conclusion Motor acupuncture based on movement pattern adjustment theory can achieve significant therapeutic effect in treating NLBP, which can effectively alleviate pain, improve lumbar function, and reduce inflammatory reactions, with good prognosis and a low recurrence rate.

Hepatic encephalopathy (HE) is a common complication and an independent risk factor for death in patients with liver cirrhosis. Brain lactate level is associated with the progression and severity of HE, and research on brain lactate level may help to further explain the pathogenesis of HE. This article summarizes the metabolic process of brain lactate, the association between brain lactate level and HE, and the potential therapeutic targets for HE and provides a reference for clinicians to further systematically evaluate the progression, treatment outcome, and prognosis of patients with HE, in order to reduce the medical burden of patients and improve the prognosis of patients with HE.

OBJECTIVE: To explore the genetic etiology of 5 cases of monochorionic-diamniotic (MCDA) with genetic discordance. METHODS: 148 cases of MCDA twins who were diagnosed by amniocentesis at the Maternal and Child Health Care Hospital of Guangxi Zhuang Autonomous Region from January 2016 to June 2020 were selected as the study subjects. Relevant clinical data of the pregnant women were collected, and amniotic fluid samples of the twins were collected separately. Chromosomal karyotyping analysis and single nucleotide polymorphism array (SNP array) assay were carried out. RESULTS: The results of chromosomal karyotyping analysis showed that 5 of the MCDA twins had inconsistent chromosome karyotypes, with an incidence of 3.4% (5/148). SNP array assay showed that 3 fetuses were mosaics. CONCLUSION Genetic discordance occurs among MCDA twins, and prenatal counseling for such cases should be given by doctors with experience in medical genetics and fetal medicine, and personalized clinical management should be recommended.

Objective:To investigate the effects of dexmedetomidine combined with propofol on cognitive function, hemodynamics and diaphragm movement in elderly patients undergoing painless gastroenteroscopy.Methods:The clinical data of 82 patients who underwent painless gastroenteroscopy in Fuyang Minsheng Hospital from April 2021 to November 2022 were retrospectively collected, and they were divided into the control group and the observation group by anesthesia induction method, each group with 41 cases. The control group was anesthetized with propofol, and the observation group was anesthetized with dexmedetomidine and propofol. The recovery time, orientation recovery time and satisfaction of the two groups were compared; the cognitive function before anesthesia, 1, 12 h after anesthesia and 1, 7 d after anesthesia were compared; the changes of hemodynamics and diaphragm movement before anesthesia induction (T 0), 5 min after anesthesia induction (T 1) and at awakening (T 2) and adverse reactions were compared. Results:The recovery time, orientation recovery time in the observation group were shorter than those in the control group: (9.87 ± 1.52) min vs. (11.92 ± 1.74) min, (15.87 ± 2.31) min vs.(18.79 ± 2.54) min; the dosage of propofol was less than that in the control group: (200.21 ± 50.46) mg vs. (300.23 ± 60.29) mg; the satisfaction scores was higher than that in the control group: (9.54 ± 0.32) scores vs. (8.81 ± 0.47) scores, there were statistical differences ( P<0.05). The scores of Mini-Mental State Examination (MMSE) at 1 h after anesthesia and 12 h after anesthesia in the observation group were higher than those in the control group: (23.12 ± 1.86) scores vs. (20.31 ± 1.65) scores, (26.21 ± 1.43) scores vs. (24.12 ± 1.57) scores, there were statistical differences ( P<0.05). The scores of MMSE at 1, 7 d after anesthesia had no statistical differences between the two groups ( P>0.05). The levels of mean arterial pressure (MAP) and heart rate (HR) at T 1 and T 2 were decreased and the levels of MAP and HR at T 1 and T 2 in the observation group were higher than those in the control group: (76.48 ± 4.01) mmHg (1 mmHg = 0.133 kPa) vs. (72.31 ± 3.26) mmHg, (82.31 ± 3.27) mmHg vs. (77.97 ± 3.64) mmHg; (78.72 ± 2.17) bpm vs. (76.23 ± 2.35) bpm, (82.19 ± 3.08) bpm vs. (79.63 ± 2.56) bpm, there were statistical differences( P<0.05). The diaphragm thickness fraction (DTF) and diaphragmatic motion amplitude (DM) at T 1 and T 2 were decreased and the levels of DTF and DM at T 1 and T 2 in the observation group were higher than those in the control group: 0.21 ± 0.02 vs. 0.17 ± 0.03, 0.26 ± 0.03 vs. (0.22 ± 0.04); (15.67 ± 0.81) mm vs. (14.21 ± 0.77) mm, (16.72 ± 0.68) mm vs. (15.46 ± 0.82) mm, there were statistical differences ( P<0.05). The adverse reactions in the two groups had no significant difference ( P>0.05). Conclusions:The combination of dexmedetomidine and propofol has little effect on cognitive function, hemodynamics and diaphragm movement in elderly patients undergoing painless gastroenteroscopy, which can accelerate the recovery of patients and improve patient satisfaction.

Objective:To explore the current situation, hotspots and trends of multi-sited license of nurses in China based on China National Knowledge Infrastructure (CNKI) , Wanfang and VIP database, so as to provide reference for the research of multi-sited license of nurses in China.Methods:CiteSpace 5.1.R6 was used to conduct a visual analysis of the research on the multi-sited license of nurses in databases from the following seven aspects, including the annual number of documents, authors, institutions, journal sources, high-frequency keywords, keyword clustering and keyword burst words. The retrieval time limit was from the establishment of the database to December 31, 2021.Results:A total of 100 articles were included. The annual number of documents issued was on the rise, but the total amount was low. Among the authors, Sun Hongyan published 11 articles, ranking first. There were 88 sending agencies, with little cooperation and communication among them. The sending agencies mainly relied on universities or their affiliated hospitals. The source of journals is mainly nursing journals. There were 125 key words in total. The cluster results showed that the multi-sited license research of nurses mainly included door-to-door service, practice registration, online appointment nurses, willingness, nursing quality and influencing factors. The results of keyword burst showed that the research on influencing factors, nursing quality, Internet +, and nursing services had continued since 2020, and might continue to become research hotspots in the next few years.Conclusions:The multi-sited license of nurses in China is still in the exploratory stage, and the research content remains at the theoretical level, lacking empirical research.

Objective To investigate the safety and feasibility of the modified terminal cannula ileostomy in laparoscopic anus-preserving operation of low rectal cancer (RC).Methods The retrospective cross-sectional study was conducted.The clinicopathological data of 15 patients who underwent laparoscopic radical resection of RC + terminal cannula ileostomy in the Subei People's Hospital of Jiangsu Province between September 2016 and June 2017 were collected.The patients underwent laparoscopic low anterior resection of RC,intra-abdominal sigmoid colon-rectum end-to-end anastomosis after extracting tumor specimens,and terminal cannula ileostomy in vitro.Observation indicators:(1) intraoperative situations:operation time,time of cannula ileostomy,volume of intraoperative blood loss,number of lymph node dissected,surgical margin;(2) postoperative situations:time to initial anal exsufflation,recovery time of defecation,time of tube removal,closing time of stoma,postoperative complications,duration of hospital stay;(3) follow-up situations.Follow-up using outpatient examination and telephone interview was performed to detect the anastomotic leakage-related complications up to December 2017.Measurement data with normal distribution were represented as (x)±s.Results (1) Intraoperative situations:all the 15 patients underwent successful laparoscopic radical resection of RC + terminal cannula ileostomy,without conversion to open surgery and death.The operation time,time of cannula ileostomy,volume of intraoperative blood loss and number of lymph node dissected were respectively (170 ± 34) minutes,(23 ± 4) minutes,(59 ± 27)mL and (13 ± 5) per case.No residual cancer cells were found in resection margins.(2) Postoperative situations:time to initial anal exsufflation and recovery time of defecation in 15 patients were respectively (6± 1) days and (7 ± 1) days.The stoma was automatically closed after tube removal,and time of tube removal and closing time of stoma after tube removal were respectively (23 ± 2) days and (3 ± 1) days.The incidence of postoperative complications was 1/15.One patient with catheterization-related complications was improved by strengthening dressing and antibiotic use,and the stoma was healed at 8 days after tube removal.There was no anastomotic leakage-related complications and death.The duration of hospital stay was (15±3) days.(3) Followup situations:all the 15 patients were followed up for 6-12 months.During the follow-up,there were no anastomotic leakage-related complications and death.Conclusion The modifyied terminal cannula ileostomy is safe and feasible,and is also an ideal surgical method for preventing anastomotic leakage in the laparoscopic anuspreserving operation of low RC.

Objective: To construct the third generation chimeric antigen receptor based on a novel humanized anti-HER2 H1-2 scFv, and to investigate the specific cytotoxicity of H1-2 CAR modified T lymphocytes(CAR-T) against HER2⁺ tumor cells. Method: The expression cassette of the third generation CAR gene and anti-HER2 H1-2 scFv were constructed and cloned into lentivirus transfer plasmid, and then the third generation H1-2 CAR was transduced into human T lymphocytes using lentivirus.Enzyme linked immunosorbent assay was used to detect the expression of cytokines IL2, and LDH release assay was used to detect the cytotoxic effect of the H1-2 CAR-T.Finally, NOD/SCID mice and HER2⁺ breast cancer cell line SKBR3 were used to detect the anti-tumor effect of H1-2 CAR-T in vivo. Results: The third generation H1-2 CAR was successfully constructed.H1-2 CAR-T secreted high dose of IL2 after confrontation with HER2⁺ breast cancer cells.In vitro, the cytolytic rate of H1-2 CAR-T on high expression HER2⁺ tumor cells was significantly higher than that in low expression HER2 or non-expression HER2 tumor cells. At the efficacy to target ratio of 20, the cytolytic rate of H1-2 CAR-T against breast cancer cell SK-BR-3 could reach (90.1±2.8)%, while the cytolytic rate of H1-2 CAR-T against HER2^- breast cancer cell MDA-MB-231 was only (13.5±4.7)%. In the mouse xenograft tumor model, H1-2 CAR-T cells inhibited breast cancer growth in vivo.At the end of the experiments, the average tumor weight in the H1-2 CAR-T cell treatment group was (0.7±0.1) g, the non-transfected T cell therapeutic group was (1.2±0.2) g, and the PBS group was (1.2±0.2) g. There was significant difference between the H1-2 CAR-T therapeutic group and the non-transfected T cell therapeutic group (P<0.05). However, there was no significant difference between the non-transfected T cell therapeutic group and the PBS treatment group (P>0.05). Conclusion The HER2-sepcific H1-2 CAR-T cells specifically kill HER2 positive cells, and further studies on CAR-T cells for the treatment of HER2⁺ cancers are useful.
