Objective To explore the feasibility and safety of fastest recovery after surgery(FRAS)in laparoscopic surgery of gastrointestinal tumors.Methods The clinical data of patients undergoing laparoscopic surgery for gastrointestinal tumors under FRAS and enhanced recovery after surgery(ERAS)from Jan.2023 to May 2024 were collected,and perioperative safety and medical cost were analyzed.Results A total of 87 patients were enrolled,including 43 in the FRAS group and 44 in the ERAS group.Compared with the ERAS group,the FRAS group had significantly shorter surgical time(3.0[2.5,3.5]h vs 3.0[2.5,4.0]h),first postoperative movement time([2.85±4.29]h vs[20.18±6.13]h),first postoperative oral feeding time(2.0[2.0,3.0]h vs 24.0[15.0,48.0]h),postoperative hospital stay(24.0[20.0,40.0]h vs 192.0[150.0,216.0]h),lower hospitalization costs(50 515.61[46 650.44,56 827.12]yuan vs 65 555.09[58 683.21,86 239.02]yuan),and lower medication costs(2 671.09[2 063.31,3 127.09]yuan vs 7 326.90[5 104.66,10 674.26]yuan)(all P＜0.05).Conclusion It is safe and feasible to use FRAS during the perioperative period of laparoscopic radical gastrectomy for gastrointestinal tumors,and FRAS can also reduce the costs of hospitalization and medications.

Academic buoyancy refers to the ability of students to successfully overcome typical, non-major academic setbacks and challenges encountered in daily school life. It can affect students' academic behaviors, academic achievements, and emotional experiences. This paper reviews academic buoyancy from four perspectives: its definition, measurement tools, effects, and intervention strategies. Additionally, it analyzes the applicability of introducing academic buoyancy to nursing students in China, with the aim of providing a new perspective to alleviate academic pressure and improve academic behaviors among nursing students.

Objective:To explore and analyze the characteristics and influencing factors of language development in children with attention deficit hyperactivity disorder (ADHD).Methods:A case-control study was used, from May 2021 to August 2023, patients diagnosed with attention deficit hyperactivity disorder (ADHD) were enrolled in the mental health clinic of the Children′s Hospital Affiliated to the Capital Institute of Pediatrics. The language ability of 272 children with ADHD and 117 healthy children who underwent physical examination in children′s health center during the same period were tested by Diagnostic Receptive and Expressive Assessment of Mandarin-Comprehensive (DREAM-C), and the development levels of total language, receptive, expressive, semantics and syntax of the two groups were compared by independent sample t-test. The influential factors of language lag in children with ADHD were analyzed by univariate χ2 analysis and multiple logistic regression. Results:There were 272 children with ADHD, including 206 males and 66 females, with an age range of 6-8 (7.29±1.17) years. While in the control group, there were 117 healthy children, including 91 males and 26 females, with an age range of 6-8 (7.02±0.82) years. The average scores of total language, expressive and syntax of ADHD children were lower than those of healthy children [(92.73±12.47/96.36±11.04), t=-2.857, P<0.05; (84.49±13.24/87.78±15.25), t=-2.029, P<0.05; (87.93±10.26/90.27±11.05), t=2.022, P<0.05]. Univariate χ2 analysis showed that disharmonious family relationship ( χ2=4.183, P<0.05), the main caregivers were non-parents ( χ2=9.121, P<0.05), early screen exposure ( χ2=3.889, P<0.05), ADHD family history ( χ2=5.423, P<0.05) were influential factors of language development lag in ADHD children. The results of multivariate logistic regression model analysis showed that cesarean section ( OR=2.137, 95% CI: 1.078-4.379, P=0.030), disharmonious family relationship ( OR=2.659, 95% CI: 1.178-5.999, P=0.019), early screen exposure ( OR=3.556, 95% CI: 1.127-11.213, P=0.030), ADHD family history ( OR=1.959, 95% CI: 1.058-3.630, P=0.033) were risk factors for comorbidities of language development in children with ADHD. Conclusion:The total language ability, expressive and syntax scores of ADHD children lag behind those of healthy children. The delayed language development of ADHD children is related to delivery mode, family relationship, the main caregivers, early screen exposure, family history of ADHD.

With the increasing proportion of human papilloma virus(HPV)infection in the pathogenic factors of oro-pharyngeal cancer,a series of changes have occurred in the surgical treatment.While the treatment mode has been im-proved,there are still many problems,including the inconsistency between diagnosis and treatment modes,the lack of popularization of reconstruction technology,the imperfect post-treatment rehabilitation system,and the lack of effective preventive measures.Especially in terms of treatment mode for early oropharyngeal cancer,there is no unified conclu-sion whether it is surgery alone or radiotherapy alone,and whether robotic minimally invasive surgery has better func-tional protection than radiotherapy.For advanced oropharyngeal cancer,there is greater controversy over the treatment mode.It is still unclear whether to adopt a non-surgical treatment mode of synchronous chemoradiotherapy or induction chemotherapy combined with synchronous chemoradiotherapy,or a treatment mode of surgery combined with postopera-tive chemoradiotherapy.In order to standardize the surgical treatment of oropharyngeal cancer in China and clarify the indications for surgical treatment of oropharyngeal cancer,this expert consensus,based on the characteristics and treat-ment status of oropharyngeal cancer in China and combined with the international latest theories and practices,forms consensus opinions in multiple aspects of preoperative evaluation,surgical indication determination,primary tumor re-section,neck lymph node dissection,postoperative defect repair,postoperative complication management prognosis and follow-up of oropharyngeal cancer patients.The key points include:① Before the treatment of oropharyngeal cancer,the expression of P16 protein should be detected to clarify HPV status;② Perform enhanced magnetic resonance imaging of the maxillofacial region before surgery to evaluate the invasion of oropharyngeal cancer and guide precise surgical resec-tion of oropharyngeal cancer.Evaluating mouth opening and airway status is crucial for surgical approach decisions and postoperative risk prediction;③ For oropharyngeal cancer patients who have to undergo major surgery and cannot eat for one to two months,it is recommended to undergo percutaneous endoscopic gastrostomy before surgery to effectively improve their nutritional intake during treatment;④ Early-stage oropharyngeal cancer patients may opt for either sur-gery alone or radiation therapy alone.For intermediate and advanced stages,HPV-related oropharyngeal cancer general-ly prioritizes radiation therapy,with concurrent chemotherapy considered based on tumor staging.Surgical treatment is recommended as the first choice for HPV unrelated oropharyngeal squamous cell carcinoma(including primary and re-current)and recurrent HPV related oropharyngeal squamous cell carcinoma after radiotherapy and chemotherapy;⑤ For primary exogenous T1-2 oropharyngeal cancer,direct surgery through the oral approach or da Vinci robotic sur-gery is preferred.For T3-4 patients with advanced oropharyngeal cancer,it is recommended to use temporary mandibu-lectomy approach and lateral pharyngotomy approach for surgery as appropriate;⑥ For cT1-2N0 oropharyngeal cancer patients with tumor invasion depth＞3 mm and cT3-4N0 HPV unrelated oropharyngeal cancer patients,selective neck dissection of levels ⅠB to Ⅳ is recommended.For cN+HPV unrelated oropharyngeal cancer patients,therapeutic neck dissection in regions Ⅰ-Ⅴ is advised;⑦ If PET-CT scan at 12 or more weeks after completion of radiation shows intense FDG uptake in any node,or imaging suggests continuous enlargement of lymph nodes,the patient should undergo neck dissection;⑧ For patients with suspected extracapsular invasion preoperatively,lymph node dissection should include removal of surrounding muscle and adipose connective tissue;⑨ The reconstruction of oropharyngeal cancer defects should follow the principle of reconstruction steps,with priority given to adjacent flaps,followed by distal pedicled flaps,and finally free flaps.The anterolateral thigh flap with abundant tissue can be used as the preferred flap for large-scale postoperative defects.

Conclusion:The total language ability, expressive and syntax scores of ADHD children lag behind those of healthy children. The delayed language development of ADHD children is related to delivery mode, family relationship, the main caregivers, early screen exposure, family history of ADHD.

Objective:To revise the family resilience assessment scale (FRAS) in patients with stroke and to evaluate its psychometric properties and applicability.Methods:FRAS was authorized and translated into Chinese.The scale items were revised based on the interview results of 13 patients with stroke and 11 caregivers and the opinions of 20 experts in related fields.A convenience sampling method was used to sample neurology and neurosurgery inpatients from 2 tertiary hospitals in Hangzhou twice from June to November 2022, with 325 questionnaires (sample 1) distributed the first time for item analysis and exploratory factor analysis, and 285 questionnaires (sample 2) distributed the second time for confirmatory factor analysis, criterion validity and reliability test.Data analysis was conducted by SPSS 26.0 and AMOS 24.0.Results:The exploratory factor analysis extracted 6 common factors(family beliefs, family spirit, family connection, family resources, family communication, family collaboration) with 32 items.Confirmatory factor analysis showed that the model fit well( χ2/ df=2.67, RMSEA=0.025, CFI=0.98, GFI=0.90, IFI=0.98, RMR=0.031). The cronbach's α coefficient of the total scale was 0.96, and 0.82-0.92 for the dimensions.The 2-week retest reliability was 0.99.The total scale score was positively correlated with the validity scale (family resilience scale) ( r=0.882, P<0.001). Conclusion:The family resilience scale for patients with stroke has good reliability and validity and can be used to assess the family resilience of patients with stroke.

Objective To explore the clinical feature,treatment and prognosis of incidental prostate cancer(IPC) after transurethral resection of the prostate (TURP) for benign prostatic hyperplasia (BPH).Methods From January 2009 to April 2017,24 cases undergoing TURP for benign prostatic hyperplasia and being diagnosed with prostate cancer(T1a-T1b) was retrospectivey analysed,who aged from 62 to 84 years (mean 71.8 years).Digital rectal examination (DRE) showed prostate medium texture,smooth surface,and no nodules.Ultrasound presented no low echo nodules in the prostate.Prostate volumes were 19.2-93.4 ml,with median of 40.1 ml.PSA were 1.81-9.11 ng/ml,with median of 4.12 ng/ml.The patients with PSA between 6-10 ng/ml accepted prostate biopsy,and pathological results were negative.Results The The pathology of TURP specimens in 24 cases were diagnosed prostate cancer (21 cases of T1a,3 cases of T1b).According to the new WHO/ISUP classification group,there were 18 cases of hierarchical group 1,3 cases of hierarchical group 2,1 case of hierarchical group 3,2 cases in hierarchical group 4.All patients were treated with hormonal therapy,and 7 cases (5 cases of hierarchical group 1,and 2 cases of hierarchical group 2) underwent laparoscopic radical prostatectomy (LRP) after 3 months of hormonal therapy.The specimens of prostatectomy were examined by whole-mount serial,showing 3 cases of prostate cancer (T1a) with negative margin,and 4 cases of benign prostate cells.They were followed up for 5-82 months with median of 43.5 months.No biological progression or tumor progression was found,and,1 case died of colon cancer after 26 months of follow-up.The patients' age and Gleason score of stage T1b were higher than that of stage T1a.Prostate volume and preoperative PSA had no statistically significant difference between the two stages.Conclusions The patients' age and Gleason score of stage T1b were higher than that of stage T1b.The proportion of residual tumor following TURP was high.The prognosis of incidental prostate cancer was good by hormonal therapy or radical prostatectomy.

Objective To explore the treatment and diagnostic value of combined detection of high sensitivity C reactive protein(hs-CRP) and D-dimer (DD) levels for carotid artery plaque (CAS) in patients with acute cerebral infarction(ACI).Methods 48 patients with ACI were selected as the observation group,while 48 healthy people who excluded ACI were selected as the control group.The vascular ultrasonography and serum levels of hs-CRP and DD were detected within 3 days,and the observation group was classified according to TOAST.Results The hs-CRP and DD levels in the observation group were (7.88 ±2.54)mg/L and (1 286.2 ±233.4) μg/L,respectively,which were significantly higher than (1.14 ± 0.32) mg/L and (462.8 ± 147.2) μg/L in the control group (t =15.53,20.67,all P ＜ 0.05).The differences of hs-CRP and DD levels in different TOAST subtypes ACI patients were not statistically significant(P ＞0.05).The hs-CRP level was positively correlated with the number of instability carotid plaque(r =0.465,P =0.000),and DD level had no significant correlation with the number of instability carotid plaque.Conclusion Elevated serum hs-CRP and DD levels in ACI patients confirmed its participation in the acute inflammatory response,and hs-CRP can better reflect the instability of ACI patients with CAS.

Objective To investigate the effects of mefformin on the differentiation of osteoclastas well as relative mechanism.Methods Raw264.7 cells from the murine macrophage cell line was used.Receptor activator of NF-κB ligand (RANKL) was used to stimulate osteoclast differentiation from Raw264.7 cells.Osteoclast differentiation was assessed by tartrate-resistant acid phosphatase (TRAP) and actin fluorescence staining and counting the TRAP-positive cells after exposure to different concentrations of mefformin (0 μmol/L,400 μmol/L,800 μmol/L and 1000 μmol/L) or rapamicin (100 nmol/L) in the presence of 50 ng/ml RANKL for 5 days.Bone-resorbing activity was evaluated by BD BioCoatTM OsteologicTM Bone Cell Culture System.The expression of osteoclast-specific genes like TRAP,capthesin K,calcitonin receptor (CTR) and matrix metalloproteinase (MMP-9) was evaluated by RT-PCR.The expression of tumor necrosis factor-α(TNF-ct) S6K1Thr389,S6 Ser235/236,4E-BP1Thr37/46 and c-Fos protein was evaluated by ELISA kit and Western blot analysis,respectively.Results Mefformin dose-dependently inhibited RANKL-stimulated osteoclasts differentiation in Raw264.7 cell culture,as manifested by decrease of TRAP-positive multinucleated cells and pit erosion area,down-regulation of TRAP,cathepsin K,CTR and MMP-9 mRNA and reduction of TNF-α and c-Fos protein expression.Further study revealed that RANKL activated mTOR complex 1(mTORC1) signaling,while mefformin impaired RANKL-stimulated mTORC1 signaling.Rapamycin,an mTORCl-specific inhibitor and immunosuppressive macrolides could also prevent RANKL-induced osteoclast differentiation and bone resorption in vitro.Conclusion Mefformin inhibits osteoclastogenesis in vitro,which may due to reduction of TNF-α and c-Fos protein expression,and mTORC1 signaling is involved in this process.
