Objective To investigate the changes of autoantibodies in hepatitis B disease and its clinical sig-nificance.Methods 418 cases of hepatitis B patients were selected as hepatitis B group.At the same time,148 hos-pitalized patients in our hospital with autoimmune hepatitis( AIH) were chosen as AIH group.And 100 healthy people with physical examination were selected as control group at the same time .The antinuclear antibodies , anti -smooth muscle antibody( SMA) and anti-kidney microsomal antibodies and other autoantibodies of the three groups were detected and analyzed statistically.Results ANA-positive rate of hepatitis B group was 22.73%,ANA titer was mainly 1:100,only two cases of liver cirrhosis titers were 1:320,ANA karyotype was mainly homogenous,only four cases belonged speckled pattern;ANA positive rate of AIH patients was 60.14%,ANA titer was mainly 1:320,or even 1:1 000, primarily as a spot -type karyotype, nucleolar and centromere type.Differences between the two groups were statistically significant (P<0.05).The positive rates of hepatitis B,chronic hepatitis,severe hepatitis B and hepatitis B patients with cirrhosis ANA were significantly higher than in patients with acute hepatitis B,the differ-ences were statistically significant (χ2 =12.172,12.560,28.123,all P<0.05).Compared with AIH group,the posi-tive rate of SMA and LKM in patients with hepatitis decreased 51.98%,32.22%,respectively,the differences were statistically significant (χ2 =196.843,107.357,all P<0.05).The positive rate of hepatitis B level ANA ( +) patients of ALT and AST,HBV DNA was significantly higher than ANA (-) group.The level of hepatitis B patients ALT and AST,HBV DNA positive group were significantly higher than AIH.Differences were statistically significant (all P<0.05).Conclusion Autoantibody detection helps to study autoimmune etiology and pathogenesis of great importance for patients with hepatitis B and cirrhosis,but the reaction involved in the pathogenesis of autoimmune hepatitis level research still needs to be deeper.

AIMTo further elucidate the role of agmatine on the pharmacological effects of opioids. METHODSThe effect of L-arginine and L-arginine decarboxylase(L-ADC) antibodies on pain threshold, morphine ntinociception and tolerance were investigated in mouse acetic acid writhing test, mouse radiant heat tail flick test and mouse hot plate test. RESULTSIn mouse acetic acid writhing test, intracerebroventricular injection of L-arginine dose-ependently inhibited the writhing of mice compared with saline control. L-arginine did not influence the tail flick latency itself in mouse radiant heat tail flick test, but enhanced antinociceptive effect of morphine in a dose-dependent manner. The possible maximal analgesia percentage of morphine 2.5 mg*kg-1 was increased from 23% to 71%. Furthermore, L-arginine inhibited acute tolerance induced by morphine 100 mg*kg-1in mouse radiant heat tail flick test. The effect of L-arginine as mentioned above could be antagonized by idazoxan (3 mg*kg-1, ip), which is a selective antagonist of imidazoline receptors. L-ADC specific antibodies inhibited morphine antinociception and promoted the development of tolerance to morphine in mouse radiant heat tail flick test and 55℃ hot plate test. CONCLUSIONL-Arginine and L-ADC play important roles in the formation of pain threshold, morphine antinociception and tolerance.

Objective To explore the correlation between non-Hodgkin lymphoma (NHL) and hepatitis C virus (HCV) infection.Methods HCV infection of 208 NHL patients was investigated from the Affiliated Tumor Hospital of Zhengzhou University.Patients with leukemia or other tumors,and healthy people were used as the control and were pair matched on age and gender.ELISA method was used to detect the HCV-antibody in serum.Results HCV-antibody positive rate in NHL patients [11.5 ％ (24/208)] was significantly higher than those in leukemia patients [3.8 ％ (8/208)] (x2 =8.667,P =0.003),patients with other tumors (6/208,2.9 ％) (x2 =11.639,P =0.001) and healthy people [1.0 ％ (2/208)] (x2 =19.856,P =0.000).Conclusion HCV infection is related to NHL in Henan area.

Objective To observe dynamically the location and time of attachment and invasion of Toxoplasma gondii tachyzoites to murine intestinal mucosa by chromogenic in situ hybridization targeting SAG2 mRNA. Methods Thirty 7- to 8-week-old BALB/c mice were randomly divided into experiment group(24 mice)and control group(6 mice). Each animal in the experiment group was given 2?104 tachyzoites of RH stain in 0.2 ml PBS by intragastric administration and that in the control group was given 0.2 ml PBS. Four mice in the experiment group and one in the control group were sacrificed at 15 min,30 min,1 h,2 h,4 h and 8 h after infection,respectively,and paraffin sections of duodenum,jejunum and ileum were prepared to perform the in situ hybridization with Dig-labeled oligonucleotide probe complementary to SAG2 mRNA of T. gondii. Results Tachyzoites were found on the striated border of small intestine epithelial cells (absorptive cells,goblet cells and endocrine cells),in or between two absorptive cells or in the lamina propria. At 15 min-2 h after infection,there was significant difference in the number of attachment on jejunum and ileum (P

Objective To study the invasion and proliferation in IEC-6 cells of Toxoplasma gondii RH strain tachyzoites in vitro.Methods T.gondii tachyzoites of RH strain were co-cultured with IEC-6 cells in vitro,the process of cell adhesion,invasion and proliferation by tachyzoites was observed consecutively with inverted microscope.At 5 min,10 min,20 min,30 min,1,2,4,6,12,24 and 48 h after co-culture,the tachyzoite invasion to IEC-6 and intra-cellular proliferation were observed with Giemsa-Wright's staining,respectively.The invasive rate of tachyzoites to IEC-6 was counted.Results T.gondii tachyzoites invaded the IEC-6 cells 5 min after culture,thenceforth the invasive rate increased gradually.The invasive rate was about 55.0% at the first hour after culture with 1-5 tachyzoites in one cell.In the second hour after culture,the rate reached highest with 81.8 % and there were many pseudocysts emerging.At the same time,tachyzoites invaded the cell nucleus and proliferated in the nucleus.At the 4th hour after culture,the invasive rate began to decrease(80.8?9.2)%,the pseudocysts began to break and tachyzoites were released to cluster.The clustering tachyzoites increased significantly at the 6th hour.At the 12th hour the clustering tachyzoites decreased and most tachyzoites were free,the number of complete cells decreased obviously.There were only a few cells and pseudocysts left at the 24th hour,and a great quantity of free tachyzoites existed out of the IEC-6 cells.There were plenty of mobile tachyzoites while none of IEC-6 cells existed after 48 h culture.Conclusion IEC-6 cell may be the suitable target cell of Toxoplasma gondii tachyzoite.The tachyzoites can invade the IEC-6 cells quickly in vitro and proliferate in the plasma and nucleus with a reproductive cycle of about 6 to 12 hrs.

Objective To study the mucosal and systemic immune response after intranasal immunization with mucosal complex vaccine for Toxoplasma gondii,and to observe the protective effect on mice. Methods The mucosal complex vaccine was made of soluble tachyzoite antigen (STAg) and cholera toxin (CT),which were mixed and dissolved in PBS (1 ml PBS containing 1 mg STAg and 50 ?g CT). Fifty-two BALB/c mice were randomly divided into two groups: immunized group and control. Mice were intranasally immunized with 20 ?l mucosal complex vaccine (20 ?g STAg and 1?g CT) per mouse twice at an interval of two weeks,while the control mice were given PBS solution instead. Six mice of each group were killed by dislocation of cervical vertebra on day 14 after the last immunization. The specific IgG antibodies in serum and IgA in feces were detected by ELISA. Lymphocytes in spleen,Peyer's patches (PP) and intestinal intraepithelial lymphocyte(IEL) were isolated and counted. Percentage of CD4+ and CD8+ T cells was determined by immunocytochemistry. Other mice were challenged intragastrically each with 4?104 tachyzoites of RH strain Toxoplasma gondii on day 14 after the last immunization. Their health condition was observed and the number of tachyzoites in liver and brain was determined microscopically on the 30 th day after challenge. Results IgG antibodies in serum and IgA antibodies in feces of immunized mice were higher than the control (P

Objective To investigate the role of non-small cell lung cancer metastasis-related Trim72 gene in hepatocellular carcinoma (HCC) using clustered regularly interspaced short palindromic repeats (CRISPR) Cas9 system.Methods Hepa1-6 (Cas9) HCC cells were established with stable expression of Cas9 protein,and then specific gene knockout was performed using sgRNA targeting Trim72 gene.After obtaining the Hepa1-6 (Trim72-KO) cells,the metastasis and invasion abilities of the cells were evaluated by in vitro Transwell assay and in vivo subcutaneous lung metastasis examination.Results Hepa1-6 (Trim72-KO) cell line was successfully established by the CRISPR-Cas9 system.Transwell assay indicated that the mobility of Hepa1-6 (Trim72-KO) cells was increased compared to the control cells.Transwell assay indicated that the metastasis and invasion of Hepa1-6 (Cas9) HCC cells were enhanced after the knockout of Trim72 gene.The pathological examination of lung metastasis of subcutaneous tumor in vivo showed that the subcutaneously metastatic ability of Hepa1-6 (Trim72-KO) cells (the experimental group) was significantly stronger than Hepa1-6 (Cas9) cells (the control troup) that were not transferred to the corresponding sgRNA.Conclusions The trim72 gene knocked-out HCC cells were obtained by CRISPR-Cas9 system,which showed stronger metastasis and invasion abilities than the control cells.It is suggested that Trim72 gene may play an important role in the invasion and metastasis of HCC,and Trim 72 gene is expected to be a potential target for gene therapy of liver cancer.
