Abstract
Nasopharyngeal tuberculosis refers to the tuberculosis in the nasopharynx, which is mainly treated with systemic chemotherapy with anti-tuberculosis drugs. Here, we reported a case of nasopharyngeal tuberculosis treated by cryosurgery combined with local spraying of isoniazid on the basis of systemic chemotherapy with anti-tuberculosis drugs. By reviewing the case data and relevant literature, we understood the clinical manifestations, diagnosis and differential diagnosis of the disease, improved everyone's understanding of the disease, and proposed a new method of cryosurgery combined with local spraying of isoniazid for the treatment of nasopharyngeal tuberculosis for clinical discussion.

Abstract
Objective: To analyze the quadrivalent influenza vaccine intention of 718 health care workers (HCWs) in the Pearl River Delta region from 2015 to 2017. Method: In May 2018, 718 HCWs from the department related to the diagnosis and treatment of influenza in 17 hospitals (6 tertiary hospitals, 5 secondary hospitals and 6 primary hospitals) from Guangzhou, Jiangmen, Zhuhai and Dongguan were selected by using stratified sampling method. Questionnaire survey and face-to-face interview were used to collect the information of influenza vaccination, the intention of the quadrivalent influenza vaccine, the acceptance of free and required vaccination policies, and recommendations for increasing influenza vaccination intentions from 2015 to 2017. The multivariate logistic regression was used to analyze factors associated with the vaccination intention. Results: A total of 718 HCWs were surveyed and 147 of them were interviewed face to face. Among them, the vaccination rate of primary hospitals [17.39%(40/230)] was higher than that of other hospitals (χ(2)=15.80, P<0.05). If the vaccine could be free, 84.82% (609/718) of HCWs would like to be vaccinated. The multivariate logistic regression showed that the factors, HCWs who were aged ≥50 years (OR=3.44, 95%CI:1.43-8.28), worked in department of prevention and health care (OR=2.35, 95%CI:1.16-4.75), learned about the quadrivalent influenza vaccine (OR=2.94, 95%CI:2.08-4.18), knowed that HCWs are priority (OR=2.33, 95%CI:1.56-3.48), and had a history of trivalent influenza vaccination from 2015 to 2017 (OR=4.70, 95%CI:3.08-7.15), were associated with the vaccination intention. Conclusion: HCWs in the Pearl River Delta region had weak inclination of getting quadrivalent influenza vaccine. HCWs who were age (≥50 years old), worked in department of prevention and health care, learned about the quadrivalent influenza vaccine, knowed that HCWs are priority, and had a history of trivalent influenza vaccination from 2015 to 2017 were factors positively associated with the vaccination intention.

Abstract
The expressions of Lewis (Le) antigens, alpha-1,3/1,4 fucosyltransferases (alpha-1,3/1,4 FuTs), and metastatic potential after the treatment of 2 differentiation inducers, all- trans retinoic acid (ATRA), 8-bromo-cyclic 3',5'adenosine monophosphate (8-Br-cAMP); and 2 proliferation inducers, epidermal growth factor (EGF) and phobol-12-myristate-13-acetate (PMA), on 7721 human hepatocarcinoma cell line were studied. Cell adhesion to human umbilical vein endothelial cells (HUVEC), cell migration through transwell and invasion through matrigel were selected as the indexes of metastatic potential-related phenotypes. Using fluorescence-labelled antibodies and flow-cytometric analysis, it was found that 7721 cells mainly expressed sialyl Lewis X (SLe(x)) and a less amount of sialyl dimeric Lewis X (SDLe(x)) antigens on the cell surface. Their expressions were down-regulated by ATRA, and up-regulated by EGF. SLe(x)antigen was also decreased and increased by the treatment of 8-Br-cAMP and PMA respectively. With Northern blot to detect the mRNAs of alpha-1,3/1,4 FuTs, the main enzymatic basis for the change in SLe(x)expression was found to be the alteration of the expression of alpha-1,3 FuT-VII. It was evidenced by the observations that alpha-1,3 FuT-VII was the main alpha-1,3/1,4 FuT in 7721 cells, while alpha-1,3/1,4 FuT-III and alpha-1,3 FuT-VI were expressed rather low. The changes in the expressions of SLe(x)antigen and alpha-1,3 FuT-VII resulted in the altered cell adhesion to tumour necrosis factor-alpha stimulated HUVEC, since only the monoclonal antibody of the SLe(x), but not other monoclonal antibodies blocked the adhesion of 7721 cells to HUVEC. The migration and invasion of 7721 cells were also reduced by the treatment of ATRA or 8-Br-cAMP, and elevated by EGF or PMA. The above findings indicate that the metastatic potential of 7721 cells is suppressed by differentiation-inducers and promoted by proliferation-inducers.

Abstract
The pCMV4 plasmid containing the cancer-promoting gene, c-erbB2/neu, was cotransfected into the human hepatocarcinoma cell line 7721 with the pcDNA3 vector, which contains the 'neo' selectable marker. Several clones showing stable expression of c-erbB2/neu were established and characterized by determination of c-erbB2/neu mRNA and its encoded protein p185. Expression of Lewis antigens and alpha1,3-fucosyltransferases and the biological behavior of 7721 cells after c-erbB2/neu transfection were studied using mock cells transfected with the vectors pCMV4 and pcDNA3 as controls. SLe(x) expression on the surface of mock cells was high, whereas expression of SDLe(x), Lex and SLe(a) was absent or negligible. This is compatible with the abundant expression of alpha1,3-fucosyltransferase VII, very low expression of alphafucosyltransferase III/VI, and almost absent expression of alpha1,3-fucosyltransferase IV in the mock cells. After transfection of c-erbB2/neu, expression of SLe(x) and alpha1,3-fucosyltransferase VII were simultaneously elevated, but that of alphafucosyltransferase III/VI was not altered. The expression of both SLe(x) and alpha1,3-fucosyltransferase VII correlated positively with the expression of c-erbB2/neu in different clones, being highest in clone 13, medium in clone 6, and lowest in clone 7. In addition, the adhesion of 7721 cells to human umbilical vein endothelial cells (HUVECs) or P-selectin, as well as cell migration and invasion, were increased in c-erbB2/neu-transfected cells. These increases also correlated positively with the expression intensities of c-erbB2/neu, SLe(x) and alpha1,3-fucosyltransferase VII in the different clones, whereas cell adhesion to fibronectin correlated negatively with these variables. mAbs to SLe(x) (KM93) and SDLe(x) (FH6) significantly and slightly, respectively, abolished cell adhesion to HUVECs or P-selectin and cell migration and invasion. mAbs to SDLe(x) and SLe(a) did not suppress cell adhesion to HUVECs nor inhibit cell migration and invasion. Transfection of alpha1,3-fucosyltransferase VII cDNA into 7721 cells showed similar results to transfection of c-erbB2/neu, and the increased adhesion to HUVECs, cell migration, and invasion were also inhibited significantly by KM93 and slightly by FH6. These results indicate that expression of alpha1,3-fucosyltransferase VII and its specific product, SLe(x), and their capacity for cell adhesion, migration and invasion are closely related. Therefore, the c-erbB2/neu gene is proposed to be a metastasis-promoting gene, and its effects are at least partially mediated by the increased expression of alpha1,3-fucosyltransferase VII and SLe(x).

Abstract
The effects of all-trans retinoic acid (ATRA) and epidermal growth factor (EGF) on the expression of nm23-H1, a metastasis suppressor gene, were studied in a human 7721 hepatocarcinoma cell line. It was discovered that the expression of nm23-H1 mRNA was up-regulated by ATRA. This was compatible with the observation that the metastasis-associated phenotypes, such as chemotaxic cell migration and invasion, were both reduced in the ATRA-treated and nm23-H1-cDNA-transferred 7721 cells. However, ability of cells to adhere to fibronectin and laminin was not altered identically in the ATRA-treated and nm23-H1-cDNA-transfected 7721 cells. In contrast, the expression of nm23-H1 mRNA in 7721 cells was down-regulated both by the treatment with EGF and by the transfection of c-erbB-2/neu cDNA, which codes a protein homologous to the EGF receptor. EGF is a compound with biological effects opposite to those of ATRA, and c-erbB-2/neu is known to be a metastasis-promoting gene. These results reveal that the metastasis-preventing effect of ATRA may partly result from the up-regulation of nm23-H1, and the metastasis-promoting effects of EGF and c-erbB-2/neu were probably mediated in part by the down-regulation of nm23-H1.

Abstract
Microcrystalline cellulose triacetate (CTA) was prepared by heterogeneous acetylation of microcrystalline cellulose and used as liquid chromatographic chiral stationary phase and chiral thin layer plate to separate pharmaceutical enantiomers. The racemic Troegor's base, mathaqualone, chlormezanone and chloroquine were separated on the CTA chiral column and on the CTA chiral plate. 95% ethanol and the mixtures of 95% ethanol and water with different ratio and different pH values were used as mobile phase. The influences of eluent composition, pH and temperature on the chiral separation were discussed. The experimental results indicate that the CTA chiral plate was more sensitive to eluent composition and pH than chiral column possibly because the chiral adsorbent was not swollen on the plate.

Abstract
Porins from different neisserial strains and species have been shown to have differences in both primary amino acid sequence and biophysical characteristics as observed by functional assays. A closer examination of how the changes in the primary amino acid sequence of Neisseria porin molecules correlate with these observed biophysical changes has been impeded by the inability to easily manipulate the cloned porin genes by modern molecular techniques and then obtain enough of the expressed modified porin protein to purify and use in these biophysical functional assays. In this report, we describe a method by which the genes encoding three different porin proteins, lacking their neisserial promoter and signal sequences, were cloned into an expression plasmid and transformed into Escherichia coli. Upon induction, large amounts of the porin proteins were produced. The expressed porin proteins were then manipulated to regenerate their native trimer structure and purified by standard protein chemistry. Sufficient purified recombinant porin protein was obtained for further antigenic as well as biophysical characterization. This sets the stage for the biophysical characterization of these neisserial porin proteins in more detail.

Abstract
Spindle fiber attachments (SFAs) were enriched in a fraction of nuclei isolated from mouse livers. The enrichment method combines sonication, treatment with 2 mol/L NaCl and high speed centrifugation. SFA was enriched 27-fold on the average (n = 4) when measured by radioimmunoassay. The basic method offers opportunities for further increases of yield and for the enrichment of SFA of other vertebrates.
