BackgroundDepression is a prevalent emotional problem in adolescents， and parental psychological control is an important predictor of adolescent depression. However， existing research on the acting mechanism between the two is not adequate. ObjectiveTo explore the pathway of negative perfectionism and academic stress between parental psychological control and depressive symptoms among secondary school students， so as to provide references for reducing the incidence risk of depression in such population. MethodsFrom February to April 2023， 1 100 students across 2 middle schools and 2 high schools in Zhongshan city were selected as subjects. The survey was conducted adopting Parental Psychological Control Questionnaire， Chinese Frost Multidimensional Perfectionism Scale （CFMPS）， sense of academic stress subscale in Mental Health Inventory of Middle School Student （MMHI-60） and Center for Epidemiological Studies-Depression Scale （CES-D）. Spearman correlation analysis was adopted to examine the correlation between scores of all scales above， and Amos 24.0 was used to test the mediating path of negative perfectionism and academic stress between parental psychological control and depressive symptoms among secondary school students. ResultsAmong the 1 009 valid questionnaires withdrew （91.73% of the total）， 261 students were detected to have depressive symptoms （25.87%）. As the results of Spearman correlation analysis showed， the scores of the Parental Psychological Control Questionnaire， score of negative perfectionism dimension in CFMPS， score of sense of academic stress subscale in MMHI-60 and CES-D score were positively correlated with each other （r=0.323~0.644， P<0.05 or 0.01）. The direct effect value of parental psychological control on depressive symptoms in secondary school students was 0.128 （95% CI： 0.061~0.201）， accounting for 31.37% of the total effect. Negative perfectionism and academic stress played independently as intermediatory roles between parental psychological control and depressive symptoms in secondary school students， and the indirect effect values were 0.099 （95% CI： 0.068~0.133） and 0.100 （95% CI： 0.060~0.143）， accounting for 24.27% and 24.51% of the total effect， respectively. Negative perfectionism and academic stress acted combinedly as the chain effect pathway between parental psychological control and depressve symptoms in secondary school students， with the indirect effect value of 0.081 （95% CI： 0.060~0.106） accounting for 19.85% of the total effect. ConclusionParental psychological control can affect the depressive symptoms among secondary school students directly， and through independent or chain paths of negative perfectionism and academic stress indirectly. ［Funded by Zhongshan Social Welfare Technology Research Project （number， 2022B1060）］

OBJECTIVE: To develop a digital intelligent multimodal shift handover system for the intensive care unit (ICU) and evaluate its application effect in ICU shift handovers. METHODS: A research and development team was established, consisting of 1 department director, 1 head nurse, 3 information technology engineers, 3 nurses, and 2 doctors. Team members were assigned responsibilities including overall coordination and planning, platform design and maintenance, pre-application training, collection and organization of clinical feedback, and research investigation respectively. A digital intelligent multimodal shift handover system was developed for ICU based on the Shannon-Weaver linear transmission model. This innovative system integrated automated data collection, intelligent dynamic monitoring, multidimensional condition analysis and visual reporting functions. A cloud platform was used to gather data from multi-parameter vital signs monitors, infusion pumps, ventilators and other devices. Artificial intelligence algorithms were employed to standardize and analyze the data, providing personalized recommendations for healthcare professionals. A self-controlled before-after method was adopted. Before the application of the ICU digital intelligent multimodal shift handover system (from December 2023 to March 2024), the traditional verbal bedside handover was used; from June 2024 to March 2025, the ICU digital intelligent multimodal shift handover system was applied for shift handovers. Questionnaires before the application of the shift handover system were collected in April 2024, and those after the application were collected in April 2025. The shift handover time, handover quality (scored by the nursing handover evaluation scale), satisfaction with doctor-nurse communication (scored by the ICU doctor-nurse scale) before and after the application of the handover system were compared, and nurses' satisfaction with the shift handover system (scored by the clinical nursing information system effectiveness evaluation scale) was investigated. RESULTS: After the application of the ICU digital intelligent multimodal shift handover system, the shift handover time was significantly shorter than that before the application [minutes: 20 (15, 25) vs. 30 (22, 40)], the handover quality was significantly higher than that before the application [score: 84.0 (78.0, 88.5) vs. 71.0 (55.0, 79.0)], and the satisfaction with doctor-nurse communication was also significantly higher than that before the application (score: 84.58±6.79 vs. 74.50±11.30). All differences were statistically significant (all P < 0.05). In addition, the nurses' system effectiveness evaluation scale score was 102.30±10.56, which indicated that nurses had a very high level of satisfaction with the ICU digital intelligent multimodal shift handover system. CONCLUSIONS The application of the ICU digital intelligent multimodal shift handover system can shorten the shift handover time, improve the handover quality, and enhance the satisfaction with doctor-nurse communication. Nurses have a high level of satisfaction with this system.

Objective:To explore the symptom perception and coping experiences of patients with low anterior resection syndrome (LARS) after anus-preserving surgery for rectal cancer.Methods:This study adopted the phenomenological research method in qualitative research. From October 2022 to January 2023, purposive sampling was used to select 15 postoperative LARS patients with rectal cancer who underwent anus-preserving surgery and underwent outpatient follow-up or hospitalization at Henan Cancer Hospital as the research subject for semi-structured in-depth interviews. Colaizzi 7-step analysis method was used to analyze, summarize, and extract themes from interview data.Results:Four themes were extracted, including attitudes and emotional responses towards symptoms, daily activities influenced by symptoms, coping status with symptom management strategies, and the need for multidimensional support for symptoms.Conclusions:LARS patients after anus-preserving surgery for rectal cancer have many discomfort symptoms and are eager to receive support and assistance. Medical and nursing staff should pay attention to the complexity of patient symptom management and promptly conduct effective symptom assessment and intervention, providing patient-centered comprehensive supportive nursing, and improving their quality of life.

Objective:To investigate the application value of transverse perineal arc incision approach in complete resection of presacral cyst in the lithotomy position.Methods:The retrospec-tive cohort study was conducted. The clinicopathological data of 114 patients who underwent com-plete resection of presacral cyst in Henan Cancer Hospital from August 2012 to October 2021 were collected. There were 14 males and 100 females, aged (35±9)years. All patients were diagnosed as presacral cysts by preoperative magnetic resonance imaging. Of the 114 patients, 76 patients undergoing intraoperative perineal arc incision approach in the lithotomy position were divided into the innovative group, and 38 patients undergoing intraoperative Kraske approach were divided into the traditional group. Observation indicators: (1) surgical situations and specimen; (2) postoperative situations; (3) Follow-up. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and com-parison between groups was conducted using the chi-square test or Fisher exact probability. Results:(1) Surgical situations and specimen. The operation time, volume of intraoperative blood loss, cases with intraoperative combined transabdominal approach or sacrectomy were (137±20)minutes, (261±101)mL, 0 in the innovation group, versus (136±34)minutes, (261±116)mL, 15 in the tradi-tional group, showing no significant difference in the operation time and volume of intraoperative blood loss between the two groups ( t=0.18, 0, P>0.05) and showing a significant difference in cases with intraoperative combined transabdominal approach or sacrectomy between the two groups ( P<0.05). Results of postoperative specimen anatomy in patients of the two groups showed complete removal of the cyst. (2) Postoperative situations. The time to postoperative removing presacral drainage tube, duration of postoperative hospital stay, cases with postoperative second stage healing of incision were (11.4±2.1)days, (13.5±3.5)days, 23 in the innovation group, versus (11.5±1.9)days, (13.7±3.8)days, 4 in the traditional group, showing no significant difference in the time to post-operative removing presacral drainage tube and duration of postoperative hospital stay between the two groups ( t=-0.20, -0.24, P>0.05) and showing a significant difference in cases with postoperative second stage healing of incision between the two groups ( χ2=5.46, P<0.05). Cases with postoperative severe complications were 4 and 2 in the innovation group and the traditional group, respectively, showing no significant difference between the two groups ( P>0.05). (3) Follow-up. All 114 patients were followed up for 48(range, 6?108)months. Cases with recurrence of cysts were 2 and 0 in the innovation group and the traditional group, respectively, showing no significant difference between the two groups ( P>0.05). During the follow-up period, the anal defecation control function of all patients was classified as grade A?B of Williams score. Conclusions:The transverse perineal arc incision approach in complete resection of presacral cyst in the lithotomy position is safe and feasible. Compared with Kraske approach, the transverse perineal arc incision approach in the lithotomy position is more suitable for patients with high presacral cyst.

Objective:To explore the influencing factors and effectiveness of community follow-up in patients with cardiac implantable electronic device (CIED) implantation.Method:A total of 132 patients who received CIED implantation in the Department of Cardiology of Tongren Hospital, Shanghai Jiao Tong University School of Medicine from February 2021 to February 2022 were enrolled in this prospective cohort study. Among them 33 patients were followed up in community health service centers associated with Tongren Hospital (community follow-up group) and 99 matched patients were followed up in the CIED outpatient clinic of the hospital (outpatient follow-up group) with a ratio of 1∶3. The clinical data of the selected patients were collected through a questionnaire survey; the follow-up data were extracted through the CarelinkExpress electronic follow-up platform and the CIED outpatient information system of Tongren Hospital. Adjustment of the treatment protocol or CIED parameters at follow-up, and the referral from the community health service centers were defined as visit with-an-action (VWA). The endpoint of follow-up was the occurrence of major adverse events. The multivariate logistic regression model was used to analyze the factors influencing patient selection for community follow-up.Results:The univariate analysis showed that the frequency of visits to community health service centers and the service contracting rate in community follow-up group were higher than those of outpatient follow-up group ( P<0.05). The multivariate logistic regression analysis showed that the contracted community physician service was an independent influencing factor of patient choosing community follow-up ( OR=2.143, 95% CI: 1.103-4.166, P=0.025). A total of 469 visits of followed up occurred in 132 patients, including 45 community visits and 424 outpatient visits. VWA accounted for 22.2% (10/45) in the community follow-up group, and 17.2% (73/424) in the outpatient follow-up group ( P>0.05). There was no significant difference in the safety and effectiveness indicators (VWA, major adverse events, and unplanned follow-up) between the two groups ( P>0.05). More patients in the community follow-up group walked to the hospital than the outpatient follow-up group ( P<0.05);and the main transportation for the later was by bus or taxi(42(42.4%)or 41(41.4%)). The average waiting time in the community follow-up group was significantly shorter than that in outpatient follow-up group ( P<0.05). The total time required for a single follow-up in the community follow-up group was 50.0 (45.0, 59.5) minutes, which was significantly shorter than that in the routine outpatient follow-up group (107.0 (90.0, 135.0) minutes, P<0.05). Conclusions:The contracting with community physicians is an independent influencing factor for CIED implanted patients to choose community follow-up. The safety and effectiveness of community follow-up are comparable to routine outpatient follow-up, and community follow-up is more convenient.

Objective:To investigate the types, surgical treatments of complex intestinal fistula after radiotherapy for cervical cancer.Methods:The clinical data and treatment of 26 patients with complex intestinal fistula after radiotherapy for cervical cancer at Cancer Hospital of Zhengzhou University from Jan 2013 to Jan 2020 were reviewed .Results:Eleven patients were with recto-vaginal fistula, 1 patient with sigmoido-vesical fistula, 5 patients with combined rectal, vaginal and vesical fistula, 7 patients with low rectal fistula and peripheral infection, and 2 patients with ileo-vaginal stump fistula after radical resection of cervical cancer and adjuvant radiotherapy. All patients were underwent the surgery, including 9 patients for total pelvic or posterior pelvic resection, 6 patients for rectum or sigmoid colectomy, bladder or vaginal repair, 7 patients were done for Hartmann surgery, and 1 patient underwent segmental resection, enteroanastomosis and vaginal repair, 3 patients for transverse colostomy or proximal ileostomy. No major postoperative complications occurred . The symptoms of intestinal fistula in all patients were dissolved, and the perineal pain was significantly relieved in 23 patients. The symptoms of ileal fistula reccurred in 2 patients within 1 year after operation, and there was no mortality.Conclusions:The rectal related intestinal fistula is the most common complex intestinal fistula after radical radiotherapy for cervical cancer. The point of surgical treatment is to remove the diseased rectum or ileum.

Objective:To analyze the expression of glial fibrillary acidic protein (GFAP) and neuronal nuclei (NeuN) antigen in hippocampus based on the depression model of juvenile rats caused by chronic unpredictable stress (CUS), and to explore the effect of electroacupuncture vagus nerve on CUS depression model.Methods:Six juvenile SD rats were selected as the control group (without any stimulation), and the rest were divided into CUS group, pseudo stimulation group, fluoxetine group and electroacupuncture group by random number method after CUS modeling, with 6 rats in each group. Fluoxetine group was given 10 mg/kg fluoxetine intervention; control group and CUS group were given the same amount of normal saline intervention; In the electroacupuncture group, the distal vagus nerve was stimulated after ligation, while in the pseudo stimulation group, only vagus nerve was isolated without electrical stimulation. After 28 d of intervention, the five groups were subjected to Open-field Test and Sucrose Preference Test. Hippocampal neurons were detected by hematoxylin and eosin (HE) staining, and the expressions of GFAP and NeuN in hippocampal were detected by immunohistochemistry.Results:After CUS modeling and before intervention, the number of vertical and horizontal movements, sucrose consumption and sucrose preference in CUS group, pseudo stimulation group, fluoxetine group and electroacupuncture group were significantly lower than those in the control group (all P<0.01); After the intervention, the above indexes in CUS group and pseudo stimulation group were still lower than those in the control group (all P<0.01), but the above indexes in fluoxetine group and electroacupuncture group were significantly higher than those in CUS group and pseudo stimulation group (all P<0.01). HE staining showed that the arrangement of hippocampal neurons in CUS group and pseudo stimulation group were loose, and there were cell swelling and pyknosis, which was significantly improved in fluoxetine group and electroacupuncture group. Immunohistochemical results showed that compared with the control group, the expression of GFAP increased and NeuN decreased in the hippocampus of CUS group and pseudo stimulation group (all P<0.01); Compared with CUS group and pseudo stimulation group, the expression of GFAP decreased and NeuN increased in fluoxetine group and electroacupuncture group (all P<0.01). Conclusions:Electroacupuncture of vagus nerve can obviously improve the depression symptoms of juvenile rats, which is similar to fluoxetine, and may be related to regulating the expression of GFAP and Neun in hippocampus.

Objective:To analyze 18F-FDG PET/CT imaging features of non-functional pancreatic neuroendocrine neoplasms (NF-pNENs) and investigate its correlation with pathology and prognosis. Methods:A total of 35 cases (17 males, 18 females; age (51±12) years) of pathologically confirmed NF-pNENs who underwent pretherapeutic 18F-FDG PET/CT from January 2011 to July 2017 in Peking Union Medical College Hospital were retrospectively enrolled. Clinical data were collected and patients were followed up. PET/CT parameters including number and maximum diameter of lesions, SUV max and pancreatic tumor-to-liver ratio (T/L) were measured. Mann-Whitney U test and Kruskal-Wallis rank sum test, Spearman correlation analysis were used to analyze the data. Results:Among the included 35 NF-pNENs patients (G1, n=6; G2, n=21; G3, n=8) with maximum diameter of 3.0(2.1, 6.1) cm and SUV max of 5.5(4.0, 8.9), 32 were positive in PET/CT. There were 1 patient with cystic, 2 with calcification and 3 with dilatation of pancreaticobiliary duct. Among 10 patients with metastases, 8 revealed multiple liver metastases. There was statistical difference of T/L among G1-G3 tumor (1.23(0.60, 2.00), 3.05(1.80, 4.00), 3.90(1.90, 7.60); H=8.29, P=0.016), but there were no statistical differences of SUV max or maximum diameter among G1-G3 tumor ( H values: 4.34, 3.37, P values: 0.114, 0.186). There was a significant correlation between T/L (2.78(1.48, 3.94)) and Ki-67 index (8.0(3.0, 20.0); rs=0.631, P<0.001). Among 27 patients with available follow-up results, T/L in patients with complete remission or stable disease ( n=20) was statistically lower than that in patients with progressive disease or death ( n=7) (2.1(1.2, 3.2) vs 7.5(3.4, 13.4); z=-3.37, P=0.001). Conclusions:18F-FDG PET/CT can detect primary and metastatic lesions of NF-pNENs. T/L can better reflect the proliferative activity based on Ki-67 index than SUV max and it may be favorable on prognostic value.

The fall armyworm (FAW), Spodoptera frugiperda, is a destructive pest native to America and has recently become an invasive insect pest in China. Because of its rapid spread and great risks in China, understanding of FAW genetic background and pesticide resistance is urgent and essential to develop effective management strategies. Here, we assembled a chromosome-level genome of a male FAW (SFynMstLFR) and compared re-sequencing results of the populations from America, Africa, and China. Strain identification of 163 individuals collected from America, Africa and China showed that both C and R strains were found in the American populations, while only C strain was found in the Chinese and African populations. Moreover, population genomics analysis showed that populations from Africa and China have close relationship with significantly genetic differentiation from American populations. Taken together, FAWs invaded into China were most likely originated from Africa. Comparative genomics analysis displayed that the cytochrome p450 gene family is extremely expanded to 425 members in FAW, of which 283 genes are specific to FAW. Treatments of Chinese populations with twenty-three pesticides showed the variant patterns of transcriptome profiles, and several detoxification genes such as AOX, UGT and GST specially responded to the pesticides. These findings will be useful in developing effective strategies for management of FAW in China and other invaded areas.
