Objective:To evaluate the accuracy and ch aracteristics of combined use of 99Tcm-sulfur colloid (SC)and 9 9Tcm-diethyliminodiacetic acid (EHIDA)imaging on the diagnosis of hepat ic adenoma (HA). Methods:8 patients with HA were involved in this study.All of them were studied by nuclear medicine (NM)with dual-radiopharmaceuticals.The 99 Tcm-SC imaging was perfomed first ,then the 99Tcm-EHIDA im aging two days later,and the ratios between lesions and normal liver tissue(L/N) were calculated in terms of different counts within the same size regions of int erest (ROI) in different phases(30min,1h and 2h respectively).Some of the cases were also analysed by CT and/or MRI within one week before the operations. Results:All of the cases were submitted to surgical treatment and c onfirmed diagnosis of HA by pathology. For HA, scintigrahy presented a accuracy of 100%(8/8),which was higher than that of CT and MRI comparatively.For 99 Tcm-EHIDA imaging,there were significant differences in L/N ratios among different phases(30min,1h and 2h). Conclusion:The results show that radionuclide imaging proved to be a safe,invasive and effcetive method on the diagnosis and differential diagnosis of HA,especially ,when CT and/or MRI findings are not typical.

K88ac-LT(B) gene derived from pQE30-K88ac-LT(B) was cloned into the expression vector pLA and then the recombinant vector was transformed into the competent cells Lactobacillus casei 525. The recombinant bacteria were grown at 37 degrees C, in MRS broth. Western blotting analysis with rabbit-anti-K88ac-LT(B) polyclonal serum indicated that the recombinant protein reacted with the specific antibodies. The results showed that the molecular weight of the recombinant protein was about 71.2 kD. The K88ac-LT(B) fusion protein on the cell surface was confirmed by immunofluorescence mciroscopy and flow cytometric analysis. In addition, the survival of recombinant Lactobacillus casei 525 was studied in imitative gastrointestinal environments such as artificial gastro fluid (pH 1.5-5.5), artificial intestinal fluid, bile(0.3-3.0 g/L). The results indicated that the recombinant strain survived well in artificial gastric fluids at pH 2.5-4.5 in 5 h. The recombinant Lactobacillus casei 525 could slowly grow in the artificial intestinal fluid for different time, and could survive in 0.3% bile.

OBJECTIVETo detect the expression of Nusap1 of surgical margins in hepatocellular carcinoma (HCC) and investigate its association with early tumor recurrence.
METHODSThe expression of Nusap1 in the surgical margins of HCC, which were histopathologically negative for tumor cells, was examined using immunohistochemistry in 61 HCC cases.
RESULTSFifteen of 21 (71.4%) cases with immunohistochemical positivity for Nusap1 expression in the surgical margins had early recurrence of HCC, a rate significantly higher than that in patients with negative Nusap1 expression (12/40, 30%) (P<0.05).
CONCLUSIONSNusap1 expression in the surgical margins of HCC is closely correlated to early postoperative recurrence and can serve as an indicator for predicting early recurrence of HCC.

We isolated a novel Enterobacteria phage IME08 from hospital sewage, then confirmed it was a double-stranded DNA phage by digesting its genetic material with DNase I, RNase A and several restriction endonucleases respectively. BLAST results of random fragments generated by a random PCR cloning method revealed that it belonged to T4-like virus. We subsequently determined the host recognizing genes (g37 and g38) sequence with a PCR-based "genome jumping" protocol based on highly conserved region at 5' terminus of g37 from four other T4-like Bacteriophages (T4, JS98, T2 and K3). These molecular biological methods enabled us to readily characterize the bacteriophage and efficiently determine the sequence of the genes of interest based on very limited conserved sequence information.

ObjectiveTo identify potential distribution areas for wild Panax ginseng cultivated under forest in Liaoning province, China, and analyze the ecological factors of spatial stratified heterogeneity affecting its ecological suitability and quality suitability. MethodWild Panax ginseng samples cultivated under forest were collected from 33 cultivation bases in Liaoning province. The Maxent maximum entropy model and ArcGIS were used to delineate the ecological suitability zones. Correlation analysis was performed on seven indicators and 110 ecological factors. Variables with significant correlation (P<0.05) were used to build partial least squares regression analysis models. A comprehensive quality zoning was conducted using the analytic hierarchy process (AHP). The geographic detector was employed to analyze the interactions among dominant ecological factors of spatial stratified heterogeneity affecting habitat suitability, quality suitability, and the ecological driving factors. ResultVegetation type was the most influential ecological factor for delineating the ecological suitability zones for wild Panax ginseng in Liaoning province. The main ecological suitability areas for wild Panax ginseng cultivated under forest were located in the northeast, east, and southeast regions along the line from Xifeng County to Gaizhou City. The comprehensive quality suitability of wild Panax ginseng cultivated under forest was highest in Kuandian County and Huanren County and gradually decreased to the northwest and southwest. Within the delineated regions, the suitability conditions and comprehensive quality of wild Panax ginseng cultivated under forest were primarily influenced by the interactions between radiation and precipitation factors. The content of the measured samples was significantly higher than the standards in the 2020 edition of the Chinese Pharmacopoeia, indicating the high overall quality of wild Panax ginseng in Liaoning Province. ConclusionAccording to the zoning and prediction results, areas in Fengcheng City, Xiuyan County, Zhuanghe City, Liaoyang County, Tieling County, Xifeng County, Gaizhou City, Haicheng City, and Dashiqiao City showed large potential distribution areas with high quality, making them highly promising for wild Panax ginseng cultivation. However, further experimental verification is required. The zoning results can provide insights for research on habitat suitability and comprehensive quality accumulation of wild Panax ginseng cultivated under forest, as well as guidance for the search for potential cultivation areas and industrial development of wild Panax ginseng in Liaoning Province.

In order to investigate the apoptosis triggered by porcine circovirus type 2 (PCV2) in lymphocytes and the underlying mechanism, the levels of apoptosis and the expression levels of miRNA were examined by flow cytometry, Western blotting and real-time PCR (qPCR). The mimics or inhibitors of miR-125a-5p, an apoptosis-related miRNA, were transfected into PK-15 cells, and the apoptosis rate was examined upon overexpression or inhibition of mir-125a-5p. The target gene of mir-125a-5p was predicted by bioinformatics method, and the regulation of mir-125a-5p on the target gene was analyzed by luciferase reporter assay. The expressions of Bcl-2, Bax, cytochrome C and caspase-3 were detected by Western blotting. The results showed that exosomes secreted by PK-15 cells infected with PCV2 significantly increased the lymphocyte apoptosis rate, which was dose-dependent in certain concentration range. The expression of miR-125a-5p was dramatically increased. The apoptosis rate was increased significantly in the cells transfected with miR-125a-5p. It was predicted that there were binding sites of miR-125a-5p at Bcl-2 3'UTR by TargetScan. The luciferase activity of wild-type pmir-Bcl-2 3'UTR was inhibited significantly by miR-125a-5p mimics, but that of mutant pmir-Bcl-2 3'UTR was not changed. By Western blotting, Bcl-2 was reduced significantly, while Bax, cytochrome C and caspase-3 increased significantly, and the ratio of Bcl-2/Bax was significantly decreased. These results showed that PCV2 up-regulated the expression of miR-125a-5p through exosomes, then inhibited the expression of Bcl-2 at both mRNA and protein level, activated mitochondrial apoptosis pathway and induced apoptosis in lymphocytes.

Recombinant PRRSV △2ORF5 gene was constructed using DNA shuffling from four genetically different strains of PRRSV to study its heterologous cross-neutralizing ability. The △2ORF5 mutant gene was cloned into the vector pET-32a and transferred into E. coli BL21. SDS-PAGE confirmed that the molecular weight of the recombinant △2ORF5 was about 42 kDa, consistent with the predicted result. Then the purified recombinant protein was injected into BALB/c mouse to obtain polyclonal antibody. Western blotting analysis with mouse-anti-△2ORF5 polyclonal serum indicated that the parental virus recombinant GP5 protein reacted with the specific antibodies. Four parental viruses could be inhibited by the anti-△2ORF5 polyclonal antibody and the inhibition rates were higher than 53%. This work has laid a foundation for further development vaccine for PRRSV.
