Objective To discuss the diagnostic value of peritoneal effusion detection by emergency-ultrasound in patients with closed abdominal injury. Method From August 2006 to June 2009,212 patients with closed abdominal injury were studied to evaluate peritoneal effusion detection by emergency ultrasound. Results of 212 patients,peritoneal effusion frequency rate was 78.8%( 167/212), meanwhile,abdominal paracentesis confirmation ratio was only 46.2%(98/212). In the follow-up, 13 patients with injuried hollow viscera and 1 patient with rupture of kidney showed peritoneal effusion. The volume of abdominal fluid was increasing in 17 patients,which needed to be managed by surgery. The accuracy rates were respectively 78.3%( 112/143) and 36.1%(13/36) in the solid organs and the hollow organs. Conclusion During the course of diagnosis and treatment in closed abdominal injury,peritoneal effusion monitoring by ultrasound should be used routinely, which can help to decrease the rate of misdiagnosis and avoid delayed treatment.

Objective To investigate the effect and its molecular mechanism of phosphoglycerate mutase 5 (PGAM5) mediated pyroptosis on liver ischemia-reperfusion injury (IRI). Methods C57 mouse models of liver IRI were established and randomly divided into the 6 h reperfusion (6 h group) and 12 h reperfusion (12 h group), and sham operation group (sham group) was established too, 10 rats in each group. The effect of IRI on the parameters in the liver tissues and serum samples was evaluated. The expression levels of PGAM5 and cysteinyl aspartate specific proteinase (Caspase)-1 in the liver tissues during IRI were quantitatively detected. The IRI models of liver cells were established (IRI group). The IRI models of liver cells were established after pretreatment with Caspase-1 inhibitor Z-YVAD-FMK (inhibitor group). The untreated AML12 cells were allocated into the control group. The effect of inhibiting Caspase-1 activity on pyroptosis was analyzed. AML12 cells were transfected with PGAM5 small interfering ribonucleic acid (siRNA) (siRNA group) and siRNA-negative control (siRNA-NC) (siRNA-NC group) by liposome 3000, and then IRI models of liver cells were established. The untreated AML12 cells were assigned into the control group. The effect of PGAM5 mediated pyroptosis on IRI of liver cells was assessed. Results In the 6 h and 12 h groups, partial liver cell edema, hepatic sinusoid narrowing, central vein congestion and occasional spot necrosis were observed in the mouse liver tissues, and these changes in the 12 h group were more aggravated than those in the 6 h group. The serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in the 6 h and 12 h groups were higher than those in the sham group, and the values in the 12 h group were higher than those in the 6 h group. The levels of tumor necrosis factor (TNF)-

Objective:
To analyze the current nutritional composition of commonly consumed prepackaged foods among children in Chengdu and to provide a scientific basis for health education among children and adolescents.
Methods:
Based on the 3 day and 24 hour dietary data of children aged 6-12 in Chengdu of the Southwest China Childhood Nutrition and Growth Cohort from 2021 to 2022, the nutritional information of prepackaged foods was collected by combining offline and online methods. All foods were classified step by step, and the nutrient content of each 100 g or 100 mL food was counted and graded.
Results:
A total of 1 902 children s prepackaged foods in 23 sub categories of 10 major categories were investigated. Nuts and seeds, snack foods, instant foods and other dairy products had higher total energy(2 476, 2 027, 1 728, 1 816 kJ/100 g), with the nutrient reference value percentage(NRV%) exceeding 20%. Fish, poultry, meat, eggs and their products had the highest protein content(22.8 g/ 100 g ) with an NRV% of 38%, nuts and seeds had the highest fat content(47.5 g/100 g) with an NRV% of 79%, confectionery and jelly had the highest carbohydrate content(82.1 g/100 g) with an NRV% of 27%, and seasoning flour products had the highest sodium content with an NRV% up to 118%. Seasoning flour products and instant foods were mostly high sodium, high fat and high carbohydrate food. Baked and puffed foods were almost high fat and high carbohydrate. Fish, poultry, meat, eggs, beans and their products were rich in protein but mostly high in sodium. Beverages and cold drinks were low in other nutrients except carbohydrate.
Conclusion
The nutrient content of various prepackaged foods commonly consumed by children in Chengdu are quite different. Most of the foods consumed by children are high sodium, high fat and/or high carbohydrate. Nutrition education should be strengthened to help children choose healthy foods.

Objective:To investigate the characteristics of resting energy expenditure (REE) in children with cerebral palsy (CP) graded with different levels of Gross Motor Function Classification System (GMFCS), and to evaluate the accuracy and association of commonly used REE prediction formulas in children with CP.Methods:It was a retrospective study involving 36 children with CP aged 24-144 months who visited the Third Affiliated Hospital of Zhengzhou University between September 2021 and August 2022.REE was measured by the indirect calorimetry.Based on the GMFCS, children with CP were divided into grade Ⅰ-Ⅱ group (20 cases), grade Ⅲ group (6 cases) and grade Ⅳ-Ⅴ group(10 cases). During the same period, 11 age-matched healthy children were included in control group.The measured REE (MREE) between children with CP and healthy controls was compared.Predicted REE (PREE) calculated by the Harris-Benedict, WHO, Schofield-W, Schofield-WH and Oxford prediction formulas were compared with MREE in children for their consistency and correlation.Independent samples were analyzed using t-test or Mann- Whitney U test, and categorical data were analyzed using Chi- square test.Using paired t-test and Pearson linear correlation analysis to analyze the correlation between MREE and PREE.The accuracy of PREE values calculated by different formulas was assessed using the root mean square error. Results:The MREE in control group and children with CP were (952.18±270.56) kcal/d and (801.81±201.89) kcal/d, respectively.There was no significant difference in the MREE between grade Ⅰ-Ⅱ group versus control group[(868.30±194.81) kcal/d vs.(952.18±270.56) kcal/d, P>0.05], and grade Ⅲ group versus control group [(813.17±192.48) kcal/d vs.(952.18±270.56) kcal/d, P>0.05]. The MREE was significantly lower in grade Ⅳ-Ⅴ group than that of control group [666.00(513.50, 775.50) kcal/d vs.(952.18±270.56) kcal/d, P=0.011]. There were no significant difference between MREE and PREEs calculated by Harris-Benedict, WHO, Schofield-W, Schofield-WH, and Oxford (all P>0.05). The correct classification fraction calculated by the 5 formulas were 33.3%, 47.2%, 41.7%, 47.2%, and 41.7%, respectively.The r values of the consistency of PREE calculated by the 5 formulas were 0.585, 0.700, 0.703, 0.712, and 0.701, respectively.The Blande-Altman Limits of Agreement were (-297.77, 359.22), (-245.60, 326.94), (-250.62, 316.05), (-242.22, 177.36) and (-241.28, 325.81), respectively.The clinically acceptable range was -80.18 to 80.18 kcal/d.The root mean square error were 168.09 kcal/d, 149.64 kcal/d, 146.24 kcal/d, 144.23 kcal/d and 148.77 kcal/d, respectively. Conclusions:The MREE values decreased significantly in children with CP classified as CMFCS grade Ⅳ and Ⅴ.When REE cannot be regularly monitored by indirect calorimetry to develop nutritional support programs, children with CP may be prioritized to estimate REE using the prediction formula of Schofield-WH.

Objective:To evaluate the efficacy and safety of transhepatic arterial chemoembolization (TACE) combined with tyrosine kinase inhibitors (TKI) and programmed death-1 (PD-1) inhibitors in the treatment of patients with initially unresectable hepatocellular carcinoma.Methods:The clinical data of 42 patients with initially unresectable hepatocellular carcinoma who were admitted to the Department of Hepatobiliary and Pancreatic Surgery of the First Affiliated Hospital of Zhengzhou University from January 2020 to December 2022 were included. There were 31 males and 11 females, with a median age of 56 years old (range, 45-72 years old). All patients received TACE+ TKI+ PD-1 inhibitor combined treatment. The systemic treatment cycles were calculated by the regimen of immunotherapy. The timing of local treatment depends on tumor size, blood supply and treatment response. Patients were followed up through hospitalization, outpatient visits and telephone review. The Kaplan-Meier curves were obtained for survival analysis.Results:The dosing cycle to achieve optimal imaging response in the patients was 4 (3, 7) [ M( Q1, Q3)], with a systemic treatment time of 141 (65, 194) d [ M( Q1, Q3)] and 2 (1, 3) times [ M( Q1, Q3)] of local treatments. All patients were evaluated by modified response evaluation criteria in solid tumors criteria after treatment, including nine patients with complete response (CR), 21 with partial response, eight with stable disease, and four with progressive disease. Objective response rate and disease control rate were 71.4% (30/42) and 90.5% (38/42), respectively. Treatment-related adverse reactions occurred in 85.7% (36/42) of patients and grade Ⅲ or Ⅳ adverse reactions occurred in 16.7% (7/42). There was no level Ⅳ adverse reactions. All adverse reactions were controlled after dose reduction and symptomatic treatment. Thirteen patients (31.0%, 13/42) redeemed resectable after treatment and underwent radical surgery. Seven patients had pathological CR after surgery. In two patients, the pathological residual cancer tissue was less than 10%. The cumulative overall survival rates of the 42 patients at 6 months, 1 year, 1.5 years after treatment were 100%, 91.7%, and 65.0%, respectively. The postoperative 1-year survival rate of patients undergoing surgery after successful conversion was 83.3%. Conclusion:This study preliminarily showed the safety and efficacy of TACE, TKI, and PD-1 inhibitor combined therapy in patients with initially unresectable hepatocellular carcinoma.
