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 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.

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.

With the continuous development of science and technology,environmental pollution has become increasingly severe,which makes environmental monitoring crucial.In recent years,electrochemical sensing strategy has attracted wide attention due to its advantages such as low cost,easy operation and fast detection speed.However,the detection performance still faces many challenges such as low sensitivity,high limit of detection and poor selectivity.Metal-organic frameworks(MOFs)is a kind of ordered network porous crystal formed by the coordination bond of organic ligands and metal ions/ion clusters,which can be used to prepare high-performance electrode materials for construction of electrochemical sensors because of their characteristics of large specific surface area,adjustable pore size and diverse structure.However,the poor conductivity and stability of MOFs result in poor electrochemical detection performance,which seriously limits their extensive applications in the field of electrochemistry.Combining MOFs with other functional materials can not only overcome the inherent defects of MOFs but also have the superior properties of both MOFs and functional materials,and the synergistic effect between MOFs and functional materials is conducive to improving the detection performance.Therefore,MOFs composites have been widely used in the electrochemical detection of environmental pollutants.This paper reviewed the applications progress of electrochemical sensors based on MOFs composites(MOFs combine with carbon materials,conductive polymers,metal nanoparticles or MOFs)in detection of environmental pollutants(Pesticides,heavy metal ions,phenolic compounds and nitrites)in the past five years.The prospects and challenges of electrochemical sensors based on MOFs composites for detection of environmental pollutants were also discussed.

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.
