Objective To analyze the expression level of ATP5A1 in gastric carcinoma and its influence on the prognosis of the patients and glucose metabolism in the tumor cells.Methods We retrospectively analyzed the data of 115 patients undergoing radical resection of gastric carcinoma in our hospital from February,2013 to November,2016.ATP5A1 expression in the surgical specimens were detected using immunohistochemistry,and the long-term prognosis of the patients with high(n=58)and low ATP5A1 expression(n=57)were analyzed.In gastric carcinoma MGC803 cells,the effects of lentivirus-mediated ATP5A1 knockdown or overexpression on glucose metabolism were investigated.We also observed the growth and glucose metabolism of xenografts derived from MGC803 cells with ATP5A1 knockdown or overexpression in nude mice.Results ATP5A1 was significantly overexpressed in gastric carcinoma tissues in close correlation with blood CEA and CA19-9 levels,pathological grade,T stage and N stage(P<0.05).ATP5A1 overexpression was an independent risk factor for a significantly lowered 5-year survival rate of patients with gastric carcinoma(P<0.05).ROC curve analysis demonstrated the predictive value of high ATP5A1 expression for the patients'prognosis(P<0.001).In MGC803 cells,ATP5A1 overexpression significantly up-regulated cellular glucose uptake and lactate production and increased the protein levels of HK2,PFK1,and LDHA(P<0.05),while ATP5A1 knockdown produced the opposite changes(P<0.05).In the tumor-bearing mice,overexpression of ATP5A1 increased glucose metabolism of the tumor cells and promoted tumor growth(P<0.05).Overexpression of ATP5A1 promoted the expressions of p-JNK and p-JUN in MGC803 cells(P<0.05),and the JNK inhibitor SP600125 significantly inhibited the enhancement of cellular glucose metabolism induced by ATP5A1 overexpression(P<0.05).Conclusion High ATP5A1 expression in gastric cancer is associated a poor long-term prognosis of the patients,and its effect is mediated at least partly by promoting glucose metabolism of the cells through the JNK/JUN pathway.

ObjectiveTo investigate the therapeutic effects and difference in the effects of Arisaematis Rhizoma （AR） before and after processing （i.e.， Arisaematis Rhizoma Preparatum， ARP） with Zingiberis Rhizoma Recens-Alumen on allergic asthma in rats and to provide a basis for the theory of processing improving the efficacy. MethodA rat model of allergic asthma was established in 70 SD rats by intraperitoneal injection of ovalbumin （OVA）-aluminum hydroxide. The rats were administrated with the aqueous extracts of AR （1.2， 0.3 g∙kg^-1） and ARP （1.2， 0.3 g∙kg^-1） aqueous extracts by gavage， and montelukast sodium （0.001 g∙kg^-1） was used as the positive drug. The T helper cell type 1/type 2 （Th1/Th2） ratio in the serum and bronchoalveolar lavage fluid （BALF） and percentages of inflammatory cells in BALF were determined. Polymerase chain reaction （PCR） was employed to determine the mRNA level of mucin 5AC （MUC5AC） in the lung tissue. The pathological changes in the lung tissue were observed by hematoxylin-eosin （HE） staining and PAS staining. Immunohistochemical assay was employed to measure the expression of c-Jun amino-terminal kinase （JNK）， extracellular signal regulated protein kinase （ERK）， and p38 mitogen-activated protein kinase （p38 MAPK） in rat lung tissue. Western blot was employed to determine the protein levels of ERK， p-ERK， JNK， p-JNK， p38， p-p38 in the lung tissue. The effects of AR and ARP were compared based on overall desirability. ResultCompared with the blank group， the levels of interleukin-12 （IL-12） and γ interferon （IFN-γ） in serum and BALF of rats in the model group were significantly lower （P<0.05， P<0.01）， and the levels of interleukin-4 （IL-4）， interleukin-5 （IL-5） and interleukin-13 （IL-13） were significantly higher （P<0.05， P<0.01）. Compared with the model group， the serum and BALF contents of IL-12 and IFN-γ in rats in the montelukast sodium group， high-dose AR group and high-dose ARP group were significantly higher （P<0.05， P<0.01）， and the contents of IL-4， IL-5 and IL-13 were significantly lower （P<0.05， P<0.01）， and the serum contents of IFN-γ in rats in the low-dose AR group and low-dose ARP group were in BALF was significantly higher （P<0.05） and IL-4 and IL-13 were significantly lower （P<0.05， P<0.01）， the percentages of macrophages， lymphocytes， neutrophils， and eosinophils were reduced in BALF， and the expression of JNK/ERK/p38 MAPK signaling pathway and MUC5AC protein was inhibited in lung tissues. Overall assessment of the normalized analysis revealed that the ARP group was slightly more potent than the AR group after administration of the same dose. ConclusionAR and ARP can effectively treat allergic asthma by inhibiting JNK/ERK/p38 MAPK signaling pathway， and the effect is better after concoction， which can provide data support for its "concoction efficiency".

Objective Mobile artificial lumbar complex(MALC)which suitable for reconstruction after subtotal lumbar resection in goats was developed,and to test stability of the complex and postoperative lumbar segmental motor function.Methods Eighteen male boer goats aged from 1 to 2 years old(weighted from 35 to 45 kg)were selected and divided into con-trol group,fusion group and non-fusion group,with 6 goats in each group.According to preoperative CT scans and MRI exami-nations of lumbar,the goat MALC was designed and performed by 3D printed for non-fusion group.Operation was performed on three groups respectively,and only vertebral body and disc were exposed in control group.In fusion group,L4 part of vertebral body and the upper and lower complete disc tissues were removed,and the lumbar spine bone plate fixation was performed with titanium mesh bone grafting.In non-fusion group,vertebral body and disc were removed in the same way,and MALC was im-planted.AP and lateral X-rays of lumbar vertebrae in goat were taken at 6 months after surgery,in order to understand whether the plant was dislocated,displaced and fractured.Biomechanical tests were performed on the specimens by mechanical instru-ment to measure range of motion(ROM)of L2,3,L,4,L4,5intervertebral space and the overall ROM of L2-5 lumbar vertebrae.Results MALC of lumbar vertebra was designed by 3D printing,and its component artificial vertebrae and upper and lower ar-tificial end plates were manufactured.The semi-spherical structure was fabricated by precision lathe using high-crosslinked polyethylene material,and the prosthesis was assembled.Postoperative AP and lateral X-rays of lumbar vertebra at 6 months showed the implant position of implant and MALC were good without displacement and dislocation.In vitro biomechanical test of lumbar vertebrae specimens:(1)There were no statistical significance in ROM of lumbar intervertebral space flexion and extension,lateral flexion and rotation on L.4 and L4,5,between non-fusion group and control group(P＞0.05),while ROM of fu-sion group was significantly reduced compared with the other two groups(P＜0.05).There were no significant difference in ROM of L2.3 intervertebral flexion and extension,lateral flexion and rotation between non-fusion group and control group(P＞0.05),while fusion group was significantly increased compared with the other two groups(P＜0.001).(2)There was no signifi-cant difference in overall lumbar ROM of L2-5(P＞0.05).Conclusion The individual MALC could restore intervertebral height of lumbar vertebra while maintaining the stability of lumbar vertebra and re-establishing motor function of lumbar space.

Objective:To analyze the level and clinical significance of IL-18 and IL-18-binding protein (BP) in the bone marrow of patients with myelodysplastic syndrome (MDS) .Methods:A total of 43 newly diagnosed patients with MDS who were admitted to the Department of Hematology, Tianjin Medical University General Hospital, from July 2020 to February 2021 were randomly selected. The control group consisted of 14 patients with acute myeloid leukemia (AML) and 25 patients with iron-deficiency anemia (IDA). The levels of IL-18 and IL-18 BP in the bone marrow supernatant were measured, and their correlations with MDS severity, as well as the functionality of CD8 + T cells and natural killer cells, was analyzed. Results:The levels of IL-18, IL-18 BP, and free IL-18 (fIL-18) in the bone marrow supernatant of patients with MDS were higher than in the IDA group. The level of fIL-18 was linearly and negatively correlated with the MDS-International Prognostic Scoring System (IPSS) score. IL-18 receptor (IL-18Rα) expression on CD8 + T cells in the MDS group was lower than in the IDA group, and the levels of fIL-18 and IL-18Rα were positively correlated with CD8 + T-cell function in the MDS group. Conclusion:IL-18 BP antagonizes IL-18, leading to a decrease in fIL-18 in the bone marrow microenvironment of patients with MDS, affecting CD8 + T-cell function, which is closely related to MDS severity; therefore, it may become a new target for MDS treatment.

Objective:To explore the therapeutic effect of Shensong Yangxin capsule on patients with paroxysmal at-rial fibrillation(PAF)and its effect on serum levels of carbohydrate antigen 125(CA125),brain natriuretic peptide(BNP)and homocysteine(Hcy).Methods:A total of 106 PAF patients treated in Anhui No.2 Provincial People's Hospital between January 2020 and December 2020 were selected,randomly divided into control group(n=53)and observation group(n=53).The patients in the control group were treated with amiodarone hydrochloride tablets combined with placebo,and the patients in the observation group were treated with amiodarone hydrochloride tab-lets combined with Shensong Yangxin capsule.After 3-month treatment,the clinical efficacy,serum CA125,BNP,Hcy levels,P wave dispersion and atrial fibrillation attack frequency were compared between the two groups.Results:The total effective rate in the observation group was significantly higher than that of control group(94.34％vs.77.36％,P=0.012).Compared with control group after treatment,observation group showed a sig-nificant reduction in serum levels of CA125[(48.27±5.31)U/ml vs.(35.03±6.51)U/ml],BNP[(223.27±53.25)pg/ml vs.(156.03±33.86)pg/ml],Hcy[(14.34±3.72)μmol/L vs.(12.67±3.13)μmol/L],P wave dispersion[(46.03±3.52)ms vs.(35.27±3.31)ms]and atrial fibrillation attack frequency[(8.65±2.13)times/month vs.(4.25±1.02)times/month](P＜0.05 or＜0.01).Conclusion:Shensong Yangxin capsule can significantly improve the clinical efficacy,reduce serum levels of CA125,BNP and Hcy,and reduce atrial fibrilla-tion attack frequency in patients with paroxysmal atrial fibrillation,which is worthy of promotion and application.

A 5-year-old girl was admitted due to one episode of melena and one episode of hematemesis.Upon admission,gastroscopy revealed esophageal and gastric varices.Abdominal CT scan,MRI,and color Doppler ultrasound suggested cirrhosis,intrahepatic bile duct dilation,and bilateral kidney enlargement.Genetic testing identified compound heterozygous mutations in the PKHD1 gene:c.2264C>T(p.Pro755Leu)and c.1886T>C(p.Val629Ala).The c.2264C>T(p.Pro755Leu)mutation is a known pathogenic variant with previous reports,while c.1886T>C(p.Val629Ala)is a novel mutation predicted to have pathogenic potential according to Mutation Taster and PolyPhen2.The child was diagnosed with autosomal recessive polycystic kidney disease.In children presenting with gastrointestinal bleeding without obvious causes,particularly those with liver or kidney disease,consideration should be given to the possibility of autosomal recessive polycystic kidney disease,and genetic testing should be conducted for definitive diagnosis when necessary.

A boy,aged 14 years,was admitted due to recurrent cough and expectoration for more than 1 month,with aggravation and fever for 2 days. After admission,he presented with tachypnea and a significant reduction in transcutaneous oxygen saturation,and emergency chest CT examination showed large patchy exudation and consolidation of both lungs. The boy was given tracheal intubation and invasive mechanical ventilation immediately,and his condition was improved after active symptomatic treatment. On the 10th day of hospitalization,the boy experienced fever again,and the laboratory tests showed positive results for Epstein-Barr virus and Mycoplasma antibody IgM,along with pancytopenia,elevated triglycerides,decreased fibrinogen,and increased levels of ferritin and soluble CD25. The boy was diagnosed with hemophagocytic lymphohistiocytosis. Bone marrow biopsy showed the presence of atypical lymphocytes,and aggressive natural killer cell leukemia was considered according to clinical manifestations and flow cytometry immunophenotype. Therefore,the possibility of hemophagocytic lymphohistiocytosis should be suspected in case of severe infection with pancytopenia and rapid disease progression,and hematological malignancies should also be ruled out. Bone marrow biopsy should be performed as early as possible to make a confirmed diagnosis and perform timely treatment.

This article reports a case of prenatal diagnosis of fetal Costello syndrome. At 11 weeks of gestation, the fetal nuchal translucency thickness was 2.5 mm. At 26 +1 weeks of gestation, ultrasound indicated that the fetal abdominal circumference was significantly enlarged, suggesting fetal overgrowth. Subsequent regular ultrasound follow-ups revealed polyhydramnios, enlarged fetal kidneys, and macroglossia after 30 +5 weeks of gestation. Whole-exome sequencing of the family detected a c.34G>A(p.Gly12Ser) mutation in the fetal HRAS gene, which was pathogenic and not present in either parent. Based on clinical manifestations, the fetus was diagnosed with Costello syndrome. After genetic counseling, the pregnant woman opted for termination of the pregnancy.
