Objective To study the prognosis of hepatoblastoma (HB) in children.Methods Retrospective analysis on the clinical data and follow-up of children with HB admitted from September 2010 to February 2015 and sum up the clinical outcome and prognosis.Results Thirty-six children with HB (23 males and 13 females) were enrolled. The median age on diagnosiswas 20 months. Allthe36 patients received follow-up, the median follow-up time was 37 months (7~71 months).(1) Of the 36 patients, 8 died. The prognosis of patients with stageⅠorⅡwas signiflcantly better than those with stage Ⅲ or Ⅳ(P<0.05). The prognosis of patients with fetal type was signiflcantly better than those with other subtypes (P<0.05). (2) Serum AFP level of 35 newly diagnosed cases increased, AFP level of survivors returned to normal after treatment. Of the 8 died patients, 3 patients had AFP elevated when relapsed, 5 cases had a persistently high AFP level after adjuvant chemotherapy. The levels of LDH, CRP, and AST at diagnosis had signiflcant influence on the prognosis (P<0.05).Conclusions Serum AFP can be a monitoring indicator for recurrence and prognosis of hepatoblastoma. POG / CCG staging, pathology classiflcation are key points when assessing the prognosis of hepatoblastoma. The prognosis of patients with high levels of LDH, CRP, and AST might be worse.

Objective To investigate the relationship between the anti-earthquake military rescuers' psychosomatic health and social support, and observe the effect of intervention to the army men who suffered troubles.Methods By cluster random sampling, 152 military rescuers and 139 army men not taking part in the rescues were investigated by Facility Psychosomatic Health Scale and Social Support Rating Scale. Mental intervention or medication was performed to those produced psychosomatic health. Results The scores of somatic symptoms,mental status,psychosomatic health and social support of military rescuers and the control group were (4.09±4.70) ,(2.18 ±3.16) ,(6.27 ±7.08) ,(6.14 ±4.20) and (2.11 ±4.16) ,(1.37 ±3.09),(3.47 ±6.55),(4.57 ± 4.17 )respectively, the difference was significant(P＜0.05). The somatic symptoms had significantly positive correlation with mental status in military rescuers (r=0.17～0.52, P＜ 0.05 or 0.01 ). Failure of social support had positive correlation with mental disorders (r=0.18～0.40, P＜0.05 or 0.01). The degree of social support was the main factor which had affected on the psychosomatic health of military rescuers. The somatic symptoms of military rescuers were apparently higher than their mental symptoms. Mental and pharmaceutical intervention showed good effect on them. Conclusion There is an apparent effect for military rescuers injured seriously psychosomatic health through medication or mental intervention.

Background/Aims: Irritable bowel syndrome (IBS) is a prevalent functional gastrointestinal disease characterized by recurrent abdominal pain and bowel dysfunction. However, the majority of previous neuroimaging studies focus on brain structure and connections but seldom on the inter-hemispheric connectivity or structural asymmetry. This study uses multi-modal imaging to investigate the abnormal changes across the 2 cerebral hemispheres in patients with IBS. Methods: Structural MRI, resting-state functional MRI, and diffusion tensor imaging were acquired from 34 patients with IBS and 33 healthy controls. The voxel-mirrored homotopic connectivity, fractional anisotropy, fiber length, fiber number, and asymmetry index were calculated and assessed for group differences. In addition, we assessed their relevance for the severity of IBS. Results: Compared with healthy controls, the inter-hemispheric functional connectivity of patients with IBS showed higher levels in bilateral superior occipital gyrus, middle occipital gyrus, precuneus, posterior cingulate gyrus, and angular gyrus, but lower in supplementary motor area. The statistical results showed no significant difference in inter-hemispheric anatomical connections and structural asymmetry, however negative correlations between inter-hemispheric connectivity and the severity of IBS were found in some regions with significant difference. Conclusions The functional connections between cerebral hemispheres were more susceptible to IBS than anatomical connections, and brain structure is relatively stable. Besides, the brain areas affected by IBS were concentrated in default mode network and sensorimotor network.

Objective:To analyze the cardio-pulmonary ultrasound features of cardiogenic pulmonary edema (CPE) and pneumonia in adults with acute dyspnea, and to construct a differential diagnosis model.Methods:Seven hundred and forty-three patients with sudden acute dyspnea admitted to Hebei General Hospital from November 2018 to May 2022 were retropectively included. Ultrasonographer A performed lung ultrasound with 12 zone method, and interpreted and recorded the ultrasonic signs (including A-lines area, B-lines area, consolidation area and pleural effusion area) together with ultrasonographer B. According to the ultrasonic characteristics of the whole lung, it was divided into A-profile and B-profile. According to the continuity and symmetry of the distribution of B-lines in bilateral lung fields, it could be divided into bilateral lung continuous and discontinuous B-profile, bilateral lung symmetric and asymmetric B-profile. Left ventricular ejection fraction (LVEF), left ventricular filling pressure (E/e′), right ventricular dilatation, tricuspid annular systolic displacement (TAPSE) and inferior vena cava diameter (IVCD) were evaluated by echocardiography, and all the indexes were transformed into binary variables. According to the final clinical diagnosis and treatment results, the disease was divided into CPE group and pneumonia group. Binary Logistic regression model was used to screen independent influencing factors, and partial regression coefficient β value was used as a weight to assign a score, and a differential diagnosis model was established based on the total score. The predictive value of the model was evaluated by the receiver operating characteristic curve (ROC) and area under curve (AUC). After the model was built, 30 patients with CPE or pneumonia were independently collected by ultrasonographer C as external validation data, which were included in the model to draw ROC curve and evaluate the differential diagnosis efficiency of the model. The consistencies between ultrasonographer A and B, A and C in observing lung ultrasound were explored.Results:A total of 743 patients from 43 clinical departments were included, including 246 cases in CPE group and 497 cases in pneumonia group. Multivariate logistic regression analysis showed that bilateral lung continuous B-profile, bilateral lung symmetric B-profile, ≥1 pleural effusion area, LVEF<50%, E/e′>14 were the risk factors for CPE (all OR>1, P<0.05), and ≥1 consolidation area and ≥1 pleural sliding disappearance area were the protective factors for CPE (all OR>1, P<0.05). The sensitivity, specificity and AUC of combined cardio-pulmonary ultrasound index β value weight score in the differential diagnosis of CPE and pneumonia were 0.939, 0.956 and 0.986, respectively. The AUC of external validation data was 0.904. Ultrasonographer A and B, A and C had good consistency in the interpretation of lung ultrasound signs ( P<0.05). Conclusions:The differential diagnosis model based on combined cardio-pulmonary ultrasound indexes has high differential diagnosis efficiency for CPE and pneumonia, and can be used in bedside cardio-pulmonary ultrasound practice.

Objective:To investigate the surgical techniques and advantages of Ti-Robot-assisted surgery for pelvic fragility fractures in the elderly.Methods:A retrospective review was performed on geriatric patients presenting with pelvic fractures at the Orthopedics Department of Trauma, China-Japan Union Hospital of Jilin University from September 2019 to December 2022. Minimally invasive procedures were executed with the assistance of the Ti-Robot, and the therapeutic outcomes were appraised. The cohort comprised 24 patients aged ≥60 years, consisting of 6 men and 18 women, with a mean age of 66.1±4.9 years (range, 60-77 years). Fourteen patients sustained high-energy trauma, while 10 encountered low-energy trauma. Fracture classification utilized the FFP system proposed by Rommens and Hofmann. The cohort included 20 patients with FFP II fractures (5 males, 15 females; 4 of type IIa, 12 of type IIb, and 4 of type IIc) and 4 patients with FFP III fractures (1 male, 3 females; all type IIIa). The Matta standard assessment scale gauged fracture reduction, while the Gras classification, with Ti-Robot assistance, assessed screw positioning. Postoperative functionality was holistically assessed based on the Majeed quantitative evaluation system, focusing on pain intensity, sitting, standing, walking, and daily activities. The visual analogue scale (VAS) gauged pain levels in patients with type II fractures, pre and 72 hours post-surgery.Results:According to the Matta standard assessment scale, postoperative fracture reduction quality in 24 elderly patients showed 18 as excellent, 4 as good, and 2 as fair, yielding a 92% (22/24) combined excellent and good rate. Based on the Gras classification, 52 screws were rated as excellent and 7 as good, achieving a 100% positive rate. Utilizing Majeed's modified pelvic fracture evaluation system, postoperative functional recuperation revealed 19 patients as excellent and 5 as good. There were no reports of severe internal disease exacerbations, neurological manifestations, infections, or intraoperative extensive hemorrhaging, with all patients remaining stable. Fractures exhibited robust healing during follow-ups, averaging a recovery time of 3.5±0.7 months (range, 3-5 months). The VAS for 20 patients with FFP type II fractures decreased from 6.3±2.0 pre-surgery to 4.1±1.4 post-surgery ( t=6.14, P=0.003), signifying substantial pain mitigation. Conclusion:In the elderly with pelvic fragility fractures, particularly type II, securing with channel screws is viable. The Ti-Robot-assisted minimally invasive approach is advocated due to its potential to diminish surgical risks and expedite postoperative recuperation.
