Objective To observe the clinical efficacy of auricular point sticking plus basic nursing for constipation of excessive syndrome in acute stage of stroke.Method Ninety patients with constipation of excessive syndrome in acute stage of stroke were randomized into a treatment group and a control group, 45 cases in each group. The treatment group was intervened by auricular point sticking plus basic nursing, while the control group was by basic nursing alone. The major symptom scores were observed before intervention and after 2-treatment courses, and the clinical efficacies were compared between the two groups.Result Respectively after 1 and 2 treatment courses, there were significant differences in comparing the major symptom scores between the two groups (P<0.05). The total effective rates were respectively 60.0% and 67.5% in the treatment group respectively after 1 and 2 treatment courses, versus 37.5% and 45.0% in the control group, and the differences were statistically significant (P<0.05). Conclusion Auricular point sticking is an effective approach in treating constipation of excessive syndrome in acute stage of stroke.

Objective:To investigate the regulatory effects and mechanism of mannose-binding lectin(MBL) on autophagy during the differentiation of 3T3-L1 adipocytes, and provide the feasibility for targeting autophagy to prevent obesity and related pathological conditions in natural immunity.Methods:3T3-L1 preadipocytes were cultured in vitro and induced to differentiation. Cell differentiation and lipid accumulation were analyzed by oil red O staining and CCK-8 was used to detect the effect of different concentrations of MBL (0, 1, 5, 10 μg/ml) on cell proliferation ability at different differentiation stages. Western blot was used to analyze the expression of MBL(10 μg/ml) on the key autophagy factors LC3B, Beclin1 and p62 protein at different stages of differentiation, and the changes of lipid droplet accumulation under the intervention of MBL were observed by oil red O staining. The protein and mRNA expression of autophagy key factors under the intervention of different concentrations of MBL were detected by Western blot and qRT-PCR. And autophagy flow analysis based on autophagic degradation was used to further illustrate the autophagic activity. The expression and phosphorylation of adenosine monophosphate-activated protein kinase(AMPK)/mammalian target of rapamycin(mTOR) signaling molecules were analyzed by Western blot. Results:The results of oil red O staining showed that 3T3-L1 preadipocytes could achieve complete differentiation after 10 days of induction. CCK-8 showed that the concentration of MBL (1-10 μg/ml) in the experimental group had no effect on cell proliferation at different differentiation stages. During the differentiation of 3T3-L1 preadipocytes, Western blot and qRT-PCR showed that the expression of autophagy-related proteins and mRNA levels was enhanced in the MBL treated group, and presented a concentration-dependent relationship. Oil red O staining showed that the lipid droplets in adipocytes at different stages of differentiation are reduced to varying degrees under the intervention of MBL. Fluorescence microscopy results further confirmed that MBL enhanced the autophagy activity of adipocytes by increasing the synthesis of autophagosomes. Moreover, under the intervention of MBL, the phosphorylation level of AMPK was significantly up-regulated, while the phosphorylation level of mTOR was significantly down-regulated, also showing a concentration-dependent relationship.Conclusions:MBL accelerates the autophagy process during the differentiation of 3T3-L1 adipocytes through AMPK/mTOR signaling pathway, reduces lipid accumulation, providing a possible functional pathway for the treatment of obesity and related metabolic diseases.

Objective To observe the alterations in brain gray matter volume(GMV)in idiopathic generalized epilepsy(IGE)patients with typical absence seizure. Methods Nine IGE patients with typical absence seizure and 16 healthy volunteers were prospectively recruited from People's Hospital of Zhengzhou University from September 2012 to January 2014. By using a 3. 0T magnetic resonance imaging(MRI)and voxel - based morphometry(VBM)method, their whole brain structures and their brain GMV were scanned and analyzed,respectively,then the changes in GMV were observed. Results Compared with healthy control group,brain GMV extensively decreased in IGE patients with typical absence seizure. Thirteen regions with significant differences were as follows:the right rectal gyrus(t = 3. 13,P ﹤0. 01),the left rectal gyrus(t = 4. 82,P ﹤ 0. 01),the right calcarine/ cuneus/ gyrus lingualis/ occipital gyrus/ inferior oc-cipital gyrus(t = 6. 86,P ﹤ 0. 01),right gyrus lingualis(t = 4. 01,P ﹤ 0. 01),the left gyrus lingualis/ inferior occipital gyrus(t = 3. 73,P ﹤ 0. 01),the left inferior occipital gyrus/ gyrus lingualis(t = 5. 42,P ﹤ 0. 01),the left middle occipi-tal gyrus(t = 3. 76,P ﹤ 0. 01),the right middle occipital gyrus/ superior occipital gyrus/ middle temporal gyrus( t =3. 85,P ﹤ 0. 01),left middle temporal gyrus/ superior temporal gyrus(t = 5. 06,P ﹤ 0. 01),the right precuneus/ cuneus (t = 3. 33,P ﹤ 0. 01),and the right superior parietal lo-bule(t = 3. 66,P ﹤ 0. 01),right precentral gyrus(t = 3. 44,P ﹤0. 01),right superior frontal gyrus/ paracentral lobule/ supplementary motor area(t = 3. 50,P ﹤ 0. 01). However,GMV increase was not found. Conclusions Brain GMV extensively decreased in 13 brain regions of IGE patients with typical absence seizure,and among them occipital lobe is the most significant.

Self-assembly is the basis of the formation of biological macromolecular structure. Enzyme-instructed self-assembly (EISA) with the help of tool enzymes, realizing the conversion of small molecular compounds to supramolecular nanostructures at specific sites, become a new strategy for drug discovery.In recent years, the exploration of EISA for developing malignant cancer therapy and imaging has made considerable progress, achieving the precise regulation and tumor targeting of nanostructures. This paper reviews the latest progress of EISA in the field of tumor diagnosis and treatment, the functions and characteristics of tool enzymes such as alkaline phosphatase, sirtuin, tyrosinase, γ-glutamyltranspeptidase and caspase-3,summarizes the research status of EISA targeting multiple organelles in tumor therapy, and introduces the application of EISA in tumor imaging, aiming to provide reference forthe research of EISA strategy in tumor diagnosis and treatment.

After sequencing, we amplified and cloned foot-and-mouth disease virus (FMDV) O/QYYS/s/06 whole genome by three fragments. These three fragments were cloned into vector P43 one by one to construct recombinant plasmid P43C, which carried the full-length cDNA of FMDV O/QYYS/s/06. Then, plasmid P43C and plasmid T7 expressing T7 RNA polymerase were co-transfected into BHK-21 cells. After 48 h, we harvested the culture broth from transfected BHK-21 cells and inoculated into 2-3 day-old sucking mice. After four generation passage, the virus harvested from sucking mice was confirmed to be type O FMDV by the indirect hemagglutination test, sucking mice's neutralization test and sequencing. The results showed that we have successfully constructed the full-length cDNA clone of FMDV O/QYYS/s/06 strain.

Proteomic characterization of plasma is critical for the development of novel pharmacodynamic bio-markers.However,the vast dynamic range renders the profiling of proteomes extremely challenging.Here,we synthesized zeolite NaY and developed a simple and rapid method to achieve comprehensive and deep profiling of the plasma proteome using the plasma protein corona formed on zeolite NaY.Specifically,zeolite NaY and plasma were co-incubated to form plasma protein corona on zeolite NaY(NaY-PPC),followed by conventional protein identification using liquid chromatography-tandem mass spectrometry.NaY was able to significantly enhance the detection of low-abundance plasma proteins,minimizing the"masking"effect caused by high-abundance proteins.The relative abundance of middle-and low-abundance proteins increased substantially from 2.54%to 54.41%,and the top 20 high-abundance proteins decreased from 83.63%to 25.77%.Notably,our method can quantify approxi-mately 4000 plasma proteins with sensitivity up to pg/mL,compared to only about 600 proteins iden-tified from untreated plasma samples.A pilot study based on plasma samples from 30 lung adenocarcinoma patients and 15 healthy subjects demonstrated that our method could successfully distinguish between healthy and disease states.In summary,this work provides an advantageous tool for the exploration of plasma proteomics and its translational applications.
