Objective:To explore the direction of the association between smartphone multitasking behavior and comorbid symptoms of anxiety and depression (CAD) among college students.Methods:College students from one college located in Shanxi, Chongqing, and Shenzhen were selected between October and December 2021 using a multistage random cluster sampling method, and a follow-up visit was conducted in May 2022. The Assessment of Smartphone Multitasking for Adolescents, the Patient Health Questionnaire-9 Items, and the Generalized Anxiety Disorder Questionnaire-7 Items were used to assess the smartphone multitasking behaviors and CAD of college students. Multivariate logistic regression models were used to analyze the associations between smartphone multitasking behavior and CAD. Autoregressive cross-lagged models (ARCLM) were used to analyze the bidirectional associations between smartphone multitasking behavior and CAD.Results:A total of 953 college students were included in this study, including 323 (33.9%) males and 630 (66.1%) females, with an age of (18.89±1.33) years. The detection rates of CAD at baseline and follow-up were 25.5% and 27.5%, respectively. The mean of the total smartphone multitasking index at baseline was 2.11±0.48. The mean of smartphone and non-media activity multitasking index was 2.00±0.55. The mean of smartphone and other media activity multitasking index was 1.92±0.67. The mean of smartphone functional use multitasking index was 2.18±0.54. The multivariate logistic regression models showed that smartphone and non-media activity multitasking index ( OR=1.85, 95% CI: 1.39-2.45), smartphone and other media activity multitasking index ( OR=1.42, 95% CI: 1.10-1.83), and total smartphone multitasking index ( OR=1.66, 95% CI: 1.21-2.28) were positively associated with the risk of CAD among college students at baseline. The smartphone and non-media activity multitasking index ( OR=1.74,95% CI: 1.30-2.32), smartphone and other media activity multitasking index ( OR=1.37, 95% CI: 1.04-1.79) and total smartphone multitasking index ( OR=1.48, 95% CI: 1.06-2.06) were positively associated with the risk of CAD at follow-up. There was no statistical association between smartphone functional use multitasking index at baseline and CAD. The ARCLM showed that smartphone and non-media activity multitasking index ( β=0.974, P=0.029), smartphone and other media multitasking index ( β=0.798, P=0.003), and the total smartphone multitasking index ( β=1.379, P=0.011) at baseline could positively predict the risk of CAD at follow-up. The CAD at baseline could positively predict smartphone and other media multitasking index ( β=0.004, P=0.016) and smartphone functional use multitasking index at follow-up ( β=0.004, P=0.016). Conclusion:There is a bidirectional association between smartphone and other media activity multitasking and CAD among college students.

OBJECTIVE: To review the clinical characteristics of patients with traumatic spinopelvic dissociation (SPD) and explore the diagnostic and therapeutic methods. METHODS: A clinical data of 22 patients with SPD who underwent surgical treatment between March 2019 and August 2024 was retrospectively analyzed. There were 13 males and 9 females, with an average age of 35.5 years (range, 14-61 years). The causes of injury included falling from height in 16 cases, traffic accidents in 5 cases, and compression injury in 1 case. Sacral fractures were classified based on morphology into "U" type (9 cases), "H" type (7 cases), "T" type (4 cases), and "λ" type (2 cases). According to the Roy-Camille classification, there were 4 cases of type Ⅰ, 12 cases of type Ⅱ, 2 cases of type Ⅲ, and 4 cases of type Ⅳ. The Cobb angle was (35.7± 22.0)°. Sixteen patients were accompanied by lumbosacral trunk and cauda equina nerve injury, which was classified as grade Ⅱ in 5 cases, grade Ⅲ in 5 cases, and grade Ⅳ in 6 cases according to the Gibbons grading. The time from injury to operation was 2-17 days (mean, 5.7 days). Based on the type of sacral fracture and sacral nerve injury, 6 cases were treated with closed reduction and minimally invasive percutaneous sacroiliac screw fixation, 16 cases were treated with open reduction and lumbar iliac fixation (8 cases)/triangular fixation (8 cases). Among them, 11 patients with severe fracture displacement and kyphotic deformity leading to sacral canal stenosis or bony impingement within the sacral foramen underwent laminectomy and sacral nerve decompression. X-ray films and CT were reviewed during followed-up. The Matta score was used to evaluate the quality of fracture reduction. At last follow-up, the Majeed score was used to assess the functional recovery, and the Gibbons grading was used to evaluate the nerve function. RESULTS: All operations were successfully completed. All patients were followed up 8-64 months (mean, 20.4 months). Two patients developed deep vein thrombosis of the lower limbs, 2 had incision infections, and 1 developed a sacral pressure ulcer; no other complications occurred. Radiological examination showed that the Cobb angle was (12.0±6.8)°, which was significantly different from the preoperative one ( t=6.000, P<0.001). The Cobb angle in 16 patients who underwent open reduction was (14.9±5.5)°, which was significantly different from the preoperative one [(46.8±13.9)° ] ( t=8.684, P<0.001). According to the Matta scoring criteria, the quality of fracture reduction was rated as excellent in 8 cases, good in 7 cases, fair in 5 cases, and poor in 2 cases, with an excellent and good rate of 68.2%. Bone callus formation was observed at the fracture site in all patients at 12 weeks after operation, and bony union achieved in all cases at last follow-up, with a healing time ranging from 12 to 36 weeks (mean, 17.6 weeks). At last follow-up, the Majeed score was rated as excellent in 7 cases, good in 10 cases, fair in 4 cases, and poor in 1 case, with an excellent and good rate of 77.3%. One patient experienced a unilateral iliac screw breakage at 12 months after operation, but the fracture had already healed, and there was no loss of reduction. Among the 16 patients with preoperative sacral nerve injury, 11 cases showed improvement in nerve function (6 cases) or recovery (5 cases). CONCLUSION SPD with low incidence, multiple associated injuries, and high incidence of sacral nerve injury, requires timely decompression of the sacral canal for symptomatic sacral nerve compression, fractures reduction, deformities correction, and stable fixation.

Acute lateral ankle sprain (ALAS) is one of the most common sport injuries, with high incidence, recurrence and disability rates. Currently, exercise rehabilitation-based non-surgical treatment is the primary management approach for ALAS. However, there remain improper practices such as excessive immobilization or uncontrolled activity, which contribute to recurrent sprains and chronic ankle instability, significantly impairing patients′ athletic function and quality of life. To standardize the non-surgical management of ALAS, improve the cure rates, and reduce the recurrence and disability rates, Chinese Sports Rehabilitation Medicine Training Project of Chinese Medical Association, Foot and Ankle Basics and Orthopedics Group, Orthopedic Branch of Chinese Medical Doctor Association, and Sports Medicine Branch of Jiangsu Medical Association organized relevant experts to formulate Expert consensus on non-surgical treatment for acute lateral ankle sprain ( version 2025), following the principles of scientific vigor, practicality, and innovation. Thirteen recommendations were proposed for standardized treatment protocols across different healing phases, aiming to provide references for standard management of ALAS and improve the therapeutic outcomes.

To elucidate the genomic characteristics of Salmonella strains derived from sheep,this study employed various methods,including bacterial isolation and identification,biochemical identi-fication,pathogenicity test,whole-genome sequencing,and BLAST comparison,along with the screening of integrative conjugative elements(ICE)using ICEfinder and EasyFig for comparative analysis,as well as plasmid comparisons utilizing PlasmidBrig.The results revealed the isolation of a Gram-negative,non-spore-forming bacillus from nasal swabs of diseased sheep,which formed gray-white,smooth-surfaced,and neatly edged circular colonies on TSA sheep blood agar.On XLT-4 agar medium,it produced smooth-surfaced,white,circular colonies.The bacterium was identified as Salmonella enterica through 16S rRNA sequencing and biochemical identification.This bacteri-um induces hemorrhaging in the intestines of guinea pigs,resulting in their demise within a 48-hour period.The pathogen exhibits high virulence.Whole-genome alignment demonstrated a high degree of homology with Salmonella enterica subsp.diarizonae serotype 61:k:1,5,(7).ICE screen-ing and comparative analysis indicated the presence of a novel ICE in this strain,characterized by a core structural framework that includes an integrative shear module,a mobilizable processing mod-ule,a conjugative pair formation module,and a regulatory module.Notably,ICE from different spe-cies containing the same integrase exhibited identical inverted repeat sequences and insertion sites at tRNAPhe.Plasmid homology comparisons revealed that plasmid sequences from different strains of Salmonella enterica subsp.diarizonae serotype 61:k:1,5,(7)also showed high homology;however,the homology with plasmid sequences from other Salmonella and Escherichia coli strains was only 50％.These findings indicate that the isolated strain is Salmonella enterica subsp.diarizonae serotype 61:k:1,5,(7)and contains a novel ICE as well as a plasmid.This study fur-ther enriches the molecular epidemiology of Salmonella and provides a theoretical basis for the prevention and control of infections caused by this pathogen.

pAPN is a zinc-dependent metalloprotease,mediating the fusion between virus and host cell,and playing a role as the receptor of coronavirus.To explore the effect of pAPN on PEDV rep-lication,the full-length pAPN gene was amplified from the porcine small intestinal by PCR,and was cloned into the lentiviral vector via the homologous site digested with BamH Ⅰ and Not Ⅰ to obtain the recombinant lentiviral vector PLVX-pAPN-mCMV-ZsGreen1-puro.The recombinant lentiviral vector and helper plasmids pLP1,pLP2,pLP-VSVG were co-transfected into 293T cells for lentiviral packaging.Vero cells were infected with the packaged lentivirus and the pAPN gene overexpressing cells were screened by puromycin.The stable expression of Vero-pAPN monoclonal cell line was screened by a limited dilution method,and the effect of the cell line on the replication of PEDV was determined by qPCR for N mRNA transcription level,Western blot for N protein level,and TCID50.The results showed that the packaged lentivirus could infect Vero cells,and the monoclonal cell line Vero-pAPN(2C5)could stably expressed pAPN.The Vero-pAPN cell line can promote the replication of PEDV,the N gene mRNA transcription level was significantly different at 12-48 h(P＜0.05),the N protein expression level increased,and the TCID50 was significantly different at 24 and 48 h(P＜0.05).In conclusion,the Vero-pAPN cell line was constructed in this study and it can significantly promote the replication of PEDV,which provides a candidate cell line for PEDV vaccine production and isolation.

Objective:This study aimed to summarize and analyze the preliminary application experience of a novel pressurized intraperitoneal aerosol chemotherapy (PIPAC) device in patients with peritoneal metastases of gastrointestinal malignancies.Methods:In this descriptive case series study, four patients with pathologically confirmed peritoneal metastatic gastrointestinal malignancies were enrolled, receiving PIPAC treatment at Guangdong Provincial People's Hospital from December 2024 to February 2025. The PIPAC treatment was performed five times on these patients . Key procedural steps included equipment preparation, operation platform construction, cytologic examination of ascites, Peritoneal Cancer Index (PCI) scoring, biopsy of peritoneal metastases, drug preparation, connection and testing of the PIPAC device, PIPAC treatment, and aerosol evacuation. Preoperative and postoperative clinical data were collected and analyzed to assess the safety and feasibility of PIPAC treatment.Results:3 males and 1 female patients were enrolled; median age was 57 (range, 36-70) years old; median body mass index was 22.5 (range, 18.0-24.6) kg/m2, and the preoperative Eastern Cooperative Oncology Group (ECOG) score was 1 for all cases. Four patients successfully completed the five PIPAC treatments without any intraoperative adverse events. The PIPAC treatment time ranged from 34 minutes to 36 minutes, with a median preoperative PCI score of 18 (range, 5-25). The average Peritoneal Regression Grading Score (PRGS) before the first and second PIPAC treatments were 2.1±0.8 and 1.7±0.6, respectively. The median Visual Analog Scale (VAS) scores for pain on postoperative days 1, 2, and 3 were 2 (range, 2-4), 1 (range, 0-2), and 1 (range, 0-2), respectively. All patients resumed the oral intake and ambulation on the first postoperative day, with a postoperative hospital stay of 3 days. No postoperative complications or perioperative death occurred.Conclusion:The preliminary study results indicate that the use of the novel PIPAC device for the treatment of peritoneal metastases of gastrointestinal malignant tumors is safe and feasible.
