Objective To compare the efficacy of inhaled Iloprost and nitric oxide( NO)in infants with moderate or severe pulmonary hypertension(PH)after congenital heart disease surgery. Methods This was a prospec-tive randomized study in Children's Hospital of Fudan University from January 2011 to January 2014,including 40 in-fants who suffered from moderate to severe PH after heart surgery. Their ages ranged from 1 to 24 months. Their weight ranged from 3. 2 to 11. 0 kg. They were randomly allocated to inhale NO( NO group,n = 20)or Iloprost( Iloprost group,n = 20). Iloprost group was given Iloprost with 50 ng/(kg·min)for 10 min and then combined with NO 20 × 10 - 6 for 10 min;NO group was first given 20 × 10 - 6 of NO for 10 min,then combined with Iloprost 50 ng/(kg·min) for 10 min. Heart rate,systolic blood pressure,pulmonary artery pressure(PAP)and central venous pressure were recor-ded continuously. At the same time,the concentration of nitrogen dioxide and methemoglobin after inhaling NO was de-tected. Results Inhaled Iloprost and NO caused significant reduction in PAP(t = 4. 670,P = 0. 009;t = 3. 762,P =0. 004)and pulmonary - to - systemic pressure ratio(Pp/ Ps)(t = 16. 974,P = 0. 000;t = 9. 682,P = 0. 000)but signifi-cant increase in oxygen index separately. The combination had no additional effect compared with single application. In term of the reduction of PAP,there was no significant difference between inhaled Iloprost and NO(F = 2. 742,P =0. 129). The levels of nitrogen dioxide and methemoglobin were not above the normal limits. Conclusions Moderate to severe PH after cardiac surgery was significantly reduced by inhaled NO and Iloprost. They had similar effects. However, the combination of both vasodilators failed to prove more potent than either substance alone. Compared with the potential toxicity of NO,the individual differences and the complex transmission,Iloprost may be more reasonable and feasible for the postoperative treatment of PH.

Until now, more than seventeen parvovirus have been reported which can infect mammals and poultries. The infected cells appeared different properties of apoptosis and death, present a typical cytopathic effect. NS1 is a major nonstructural protein of parvovirus, with a conservative structure and function, which plays an important role in the viral life cycle. In addition to the influence on viral replication, the NS1 also participates in apoptosis induced by viruses. Parvovirus induced apoptosis which is mainly mediated by mitochondrial pathway, this review summarized the latest research progresses of parvovirus induced apoptosis.

Objective To share the experience of surgical repair for cor triatriatum in chidren.Methods Between July 2008 and June 2013,24 children with cor triatriatum underwent surgical correction in Cardiac Center of Children's Hospital of Fudan University.The minimum age at the time of operation was 1 month,median age was 5 month;the minimum body weight at the time of operation was 3.5 kg,median body weight was 7.4 kg.Retrospectively analyzed their cardiac anatomy,clinical data,surgical procedures and follow-up data.Results Of all 24 patients,there were 4 patients diagnosed semplice cor triatriatum,and 20 patients diagnosed cor triatriatum associated with other malformation includes cardiac and non-cardiac issues.Procedures were performed on 22 patients to correct all cardiac defects in one stage.1 patient underwent surgical repair for cor triatriatum and Glenn procedure as well.1 patient,diagnosed as cor triatriatum and functional single ventricle S/P Glenn,underwent surgical repair for cor tiratriatum only.2 patients recovered from pulmonary artery hypertension crisis after operation.1 patient dead 17 days post procedure caused by respiratory failure.23 patients discharged from hospital.The longest follow-up was 73 months,at least 12 months after discharge.All alive patients were in New York Heart Association's function class Ⅰ-Ⅱ.Echo assessment revealed normal size of left atriums of almost all alive patients one year after discharge.Till April 2015,no postoperation intervention,no blood flow obstruction at level of pulmonary veins,left atrium or mitral valve.Conclusion Pediatric patients diagnosed cor tiratriatum sinister need intervention,no matter hemodynamic change occurs or not.Right time of surgery is important for successful treatment.

Objective To investigate of the MMI-166 on the expression of MMP-2,MMP-9 and the cell apoptosis of nude mouse xenografts of SW1990 human pancreatic cancer cells.Methods Establishment of control and experimental groups,randomly,the human pancreatic cancer xenograft model of SW1990 was constructed.The control group was treated with normal saline,and experimental group was treated with MML-166 (200 mg · kg-1 · d-1).The tumor volume and tumor inhibition rate was measured by vernier caliper through length and short diameter.The expression of MMP-2 and MMP-9 protein was observed using immunohistochemistry in the tumor tissues.Apoptosis index was detected by deoxynucleotidyl transferase-mediated nick end labeling (TUNEL method).Results The tumor volume of MMI-166 group (1252.30± 464.84) mm3 was less than the control group (2241.82±208.06) mm3,significantly.The inhibition rate was 34.47％ between the experimental groups (treat with MMI-166) (1.42±0.15) g and control group (2.17±0.20) g.The expression of MMP-2 (2.80 ± 1.10) ％ and MMP-9 (2.60 ± 1.52) ％ protein was significantly downregulated in MMI-166 group,compared with the control group.Apoptotic index in the experimental group (75.60±9.71) ％ was higher than the control group (17.40 ± 10.14) ％,significantly.Conclusion The mechanism of MMI-166 inhibiting pancreatic tumor growth and inducing apoptosis may be related to the suppression of MMP-2 and MMP-9 protein expression.

Objective To observe the content of macrophage inflammatory protein-1α(MIP-1α)in plasma and bronchoalveolar lavage fluid (BALF) and the expressions of MIP-1α mRNA and nuclear factor-kappa B( NFκB)p65 mRNA in the lung of rats subjected to mechanical ventilation with high tidal volume. Method Thirty-two healthy Wistar rats were randomly ( random number) divided into control group, ventilator induced lung injury (VILI) group,dexamethasone (DEX) group and budesonide (BUD) group. The content of MIP-1α in plasma and BALF were measured with ELJSA and the expressions of MIP-1α mRNA and NF-κBp65 mRNA in lung of rat were detected by RT-PCR. The data distributed were expressed as (-x) ± s and were compared among 4 groups. Furthermore, the correlation between the content of MIP-1α and the expression of MIP-1α mRNA, and the correlation between the expression of MIP-1α mRNA and the expression of NF-κBp65 mRNA were analyzed in the latter three groups. Results With lessened lung injury ,the content of MIP-1αin plasma and BALF and the expressions of MIP-1α mRNA and NF-κBp65 mRNA in lungs of rats of DEX and BUD groups were significantly lower than those in VILI group ( P ＜ 0.001 ). Although the content of MIP-1α in plasma and BALF and the expressions of MIP-1α mRNA and NF-κBp65 mRNA in lungs of rats of BUD group were higher than those of DEX group, but no significant differences were found between them ( P ＞ 0.05). Correlation study showed that positive correlations were xisted between the MIP-1α in plasma and the expression of MIP-1α mRNA in the lungs ( r = 0.895, P ＜ 0.05)and between the expression of MIP-1α mRNA and the expression of NF-κBp65 mRNA in the lungs ( r=0.801, P ＜ 0.05). Conclusions Glucocorticoid could down-regulate the expression of MIP-1α mRNA by inhibiting the activity of NF-κB in the lungs and may have preventive and therapeutic effect to VILI to some extent. The effect of glucocorticoid used locally against VILI is simnilar to that of systemic administration with lesser adverse reactions.

Objective To investigate the expressions of Livin and vascular endothelial growth factor (VEGF)in pancreatic carcinoma and their cilinical significances.Methods The expressions of Livin and VEGF proteins were tested by immunohistochemistry in 68 cases of pancreatic carcinomas and 44 cases of adja-cent paracancerous tissues.Results The positive rates of Livin in pancreatic carcinomas and adjacent paracan-cerous tissues were 73.5% and 4.5% respectively,and the difference was statistically significant (χ2 =48.137,P<0.001).The positive rates of VEGF in pancreatic carcinomas and adjacent paracancerous tissues were 69.1% and 13.6% respectively,and the difference was statistically significant (χ2 =29.147,P <0.001).The expressions of Livin and VEGF were related with tumor differentiation (χ2 =6.061,P=0.014;χ2 =6.592,P=0.010),TNMstage (χ2 =4.175,P=0.041;χ2 =9.992,P=0.002),lymph node metasta-sis (χ2 =11.731,P=0.001;χ2 =12.002,P=0.001)and neural invasion (χ2 =9.950,P=0.002;χ2 =7.433,P=0.006).Significantly positive correlation was found between the expressions of Livin and VEGF by using Spearman correlation analysis (r=0.320,P=0.008).Survival analysis showed that the expressions of Livin and VEGF were independent prognostic factors in pancreatic carcinoma.Conclusion Livin and VEGF involve in the development,migration and metastasis of pancreatic carcinoma.Livin may upregulate the expres-sion of VEGF,which may lead to the angiogenesis and migration in pancreatic carcinoma.

Abstract As dietary issues of children and adolescents become increasingly complex, the assessment of food literacy (FL) is increasingly importance. FL involves a comprehensive cognition and practical ability concerning food among children, playing a key role in fostering healthy eating habits and improving health levels. The article explores the definition and connotations of FL, and introduces eight FL assessment tools in terms of theoretical foundations, dimensions, assessment methods, and their reliability and validity. Moreover, it provides a comparative analysis of these tools by examining their dimensional design, evaluation indicators, strengths, and weaknesses, as well as their applicable subjects and scenarios, aiming to offer references for implementing relevant policies and developing more comprehensive and effective FL assessment tools.

Objective:To discuss the clinical features, diagnosis and treatment of linear scleroderma (LS).Methods:A case of LS diagnosed in the Second Hospital of Shandong University in October 20, 2020, was reported and the clinical features and pathological documentation of the disease reported in the literature were reviewed.Results:A 24-year-old woman presented cicatricial alopecia on the left frontoparietal area and facial atrophy for about 10 years. Two years before, she began to suffer ptosis and neurological complaints. Clinical features of different stages of the disease are presented. All 15 patients reported in the literature were analyzed, with a median of 22 years and a male to female ratio of 9∶6. There were 4 cases of linear scleroderma with ipsilateral drooping eyelids and lateral contraction, 3 cases of linear scleroderma with demyelinating lesions, combined with lateral contraction, 3 cases of linear scleroderma combined with lateral atrophy, and 1 case of linear scleroderma with ipsilateral facial spasm. Two cases were with the chest sclerosing spot. Two cases of linear scleroderma were with epileptic seizure and white matter demyelination lesion. Six cases were treated with hormone, 2 cases were treated with methotrexate. One case was treated with both hormone and methotrexate. One case was treated with botulinum toxin. Three cases were treated with surgical correction of eyelid ptosis. One case was treated with ultraviolet A1 radiation phototherapy and 1 case was treated with vitamin therapy.Conclusions:Patients with scleroderma may have ipsilateral facial atrophy, blepharoptosis and facial spasm. Some patients involving the nervous system may have epilepsy and myelitis. And demyelinating lesions can be seen in magnetic resonance imaging. Localized scleroderma may develop into systemic scleroderma. Therefore, it is recommended to combine immunosuppressants as soon as possible to control the development of the disease if necessary.

Objective:To evaluate the safety and efficacy of the treatment for oppressive spinal by microwave ablation combined with percutaneous fixation and open decompression.Methods:From January 2015 to September 2018, 20 patients with 26 spinal metastatic were treated with microwave ablation combined with percutaneous fixation and open decompression, including 13 males and 7 females with an average age of 43.85±18.67 years (range, 16-79 years). The locations of the lesions included: 9 in the thoracic, 11 in the lumbar. The tumors' type: myeloma 2 cases, leukemia 1 case, liver cancer 4 cases, osteosarcoma 2 cases, lung cancer 5 cases, kidney cancer 1 case, esophagus cancer 1case, cervical cancer 1 case, intestinal cancer 1 case, prostate cancer 1 case, adenoid cystic cancer 1case. Preoperatively all the patients suffered with the local pain and the spinal cord or nerve root compression symptoms. All 20 cases were examined with CT or MRI to determine the lesions and the sizes of metastasis, as well as to evaluate the ablation zone. The entry of the pedicle screws were performed by Wiltse method through paravertebral muscles. After that the lesions were treated with partial resection for decompression of spinal cord or nerve root, and followed with microwave ablation at the metastasis site. Thermometer was used to monitor the temperature at the central and posterior edges of the vertebral body. The surrounding important tissue were cooled by ice saline. 13 patients were performed with vertebroplasty for enhancement the intensity of the vertebral body. The visual analogue scale (VAS) score was used to evaluate the effect of pain relief after surgery. The postoperative neurological function and performance status were evaluated using Frankel grading and Eastern Cooperative Oncology Group (ECOG).Results:Each lesion was heated for 5.43±2.07 min (range, 3-10 min). The power of microwave ablation was 40-60 W. The mean blood loss during operation was 852.50±514.40 ml (range, 100-1 700 ml). The mean operating time was 4.11±0.99 h (range, 2.5-6.0 h). The temperature inside the lesion was 70-85 ℃. The temperature of the surrounding tissue was maintained at<43 ℃ by repeated frozen saline flush. All cases were followed up for 8.45±2.01 months (range, 6-14 months) without any recurrence. The VAS score of the 20 patients at 48 h, 1 month, 3 months and 6 months after operation were 1.55±1.23, 2.70±0.87, 2.40±1.14 and 3.05±1.00 points, which were all statistically lowerthan the preoperative score 5.95±1.18 ( P<0.05). The Frankel grading of 14 patients had at least one grade improvement 6 months after operation. There were 8 patients shown markedly improved ECOG score 6 months after surgery. Only one case suffered from reduced myodynamiaof lower limb and covered in one month after system treatment. Conclusion:The microwave ablation combined with percutaneous fixation and open decompression could resolve the spinal and nerve compression, relieve the pain in metastatic spinal oppression, reconstruct the stability, and improve the quality of lives, which is a safe and effective palliative surgical method.
