Objective To explore the effects of nicorandil on cardiac function and clinical outcomes in patients with acute myocardial infarction (AMI) undergoing percutaneous coronary intervention (PCI). Method Sixty-six patients with AMI were randomized into a control group and nicorandil group (n = 33 for each group). In the nicorandil group, nicorandil (4 mg as a bolus injection followed by constant infusion at 8 mg/hour for 24 hours) was administered immediately after admission. Reactive oxygen species (ROS) formation was assessed by measuring urinary excretion of 8-epi-prostaglandin F2α (PGF2α) and compared between the two groups; cardiac function and cardiac events were also compared. Results Urinary 8-epi-PGF2αexcretion was increased 2-fold at 60 to 90 minutes after PCI in the control group, whereas it was unchanged in the nicorandil group (P < 0.001). Left ventricular ejection fraction and cardiac index immediately after PCI and at 6 months were greater in the nicorandil group than in the control group(P < 0.05). Rates of total inhospital cardiac events and rehospitalization were lower in the nicorandil group than in the control group (P<0.05). Conclusions Nicorandil improves cardiac function and clinical outcomes in patients with AMI undergoing primary percutaneous coronary intervention. Suppression of ROS formation may be involved in the potential mechanism.

Objective To explore the role of monitoring the cellular immune function in preventing and treating the fungal infection in the recipients of liver transplantation. Methods 679 cadaveric liver transplantations (from Jan. 2004 to Jan. 2010) were retrospectively studied. All the cases were divided into 3 groups according to different treatments and preventing regimens. The patients in groups A, B, C were treated based on the clinical experiences (394 cases), T lymphocyte subsets counting (151 cases), and combination of ATP values of CD4+ T cell and T lymphocyte subsets counting (134 cases), respectively. The infection, mortality and acute rejection rate were analyzed. The relationship between fungal infection and cellular immune function was investigated.Results The fungal infection rate in groups A, B, and C was 28. 9 %, 21.2 %, and 19. 4 % (P<0. 05), the morbidity rate was 16. 7 %, 12. 5%, and 3. 8% (P>0. 05), and the acute rejection rate was 28. 4 %, 17. 2 %, and 13. 4 % (P<0. 01), respectively. The CD4+ T lymphocyte counting in all cases of fungal infection was (147±43)×106/L. The morbidity could reach 50. 0 % when the CD4+ T lymphocyte counting < 100 ×106/L, while it was 2. 4 % when the counting was between (100-200) ×106/L (P<0. 01). The CD4+ T lymphocyte counting had no linear relation with the ATP value.The ATP value in fungal infection cases was (117 ± 61)μg/L. Conclusion The cellular immune function test could be quantitatively evaluated according to the T lymphocyte subsets and ATP value of CD4+ T lymphocyte. And individualized immunosuppressive therapy could be adjusted accordingly.Therefore, cellular immune function could be instructive in preventing and treating the fungal infection after liver transplantation.

Objective To explore the relationship between peripheral differential blood count and ATP value in Cell CD4 + T tested by ImmuKnow method in liver transplants. Methods In this study 49recipients after classic orthotopic liver transplantation (OLT) were enrolled. In a period from two weeks to two months after transplantation when all were free of glucocorticoid. Blood were sent for WBC differential samples count and ATP value in Cell-CD4 + T tested by ImmuKnow method via SPSS17. 0 software. Five more samples were selected randomly for duplicated testing of the indices in Week2, 3, 4,6 and 8 after the transplanting operation to further verify the relativity. Results White blood cell count has the highest relativity with ImmuKnow ATP value at 0. 821. The 5 recipients were repeatedly tested for ImmuKnow ATP values that were found positively correlated to cell count with a coefficient of over 0. 5. Conclusions The peripheral leukocyte count in early stage after liver transplantation is in positive correlation with ATP value in Cell CD4 + T, and the changes of numeration of leukocyte reflect changes of ATP value.

Objective:
To prepare an inactivated hepatitis A vaccine using a attenuated strain of hepatitis A virus (HAV) H2 and to analyze its immunizing dose, so as to provide the reference for development and production of inactivated hepatitis A vaccines.
Methods:
Human embryonic lung diploid cells (KMB17) were infected with attenuated HAV H2 strain to proliferate the virus, then the cells containing viruses were harvested, extracted and purified. The obtained virus concentrate was prepared into vaccine bulk and test vaccines with 1 280 EU/mL antigen content. Vaccine testing was carried out according to the inactivated hepatitis A vaccine standards specified in the Part Ⅲ of the Pharmacopoeia of the People's Republic of China (2020 edition). A total of 110 mice were randomly divided into 11 groups, including 5 dose groups (80, 160, 320, 640 and 1 280 EU/dose) of the test vaccine and the reference vaccine, as well as the adjuvant control group. Mice were immunized twice by intraperitoneal injection, their serum HAV antibodies were detected, and the geometric mean titer (GMT) and positive conversion rate of antibodies were analyzed to evaluate the immunising dose of the vaccine.
Results:
The antigen content and viral titer of the virus harvest solution were 5 120 EU/mL and 8.33 lgCCID50/mL, respectively. The removal rate of foreign protein reached 98.05% and the recovery rate of antigen was 66.25%. The test vaccine met the requirements of Part Ⅲ of the Pharmacopoeia of the People's Republic of China (2020 edition). The GMTs of HAV antibodies in the test vaccine and the reference vaccine dose groups after the second immunization were more than twice higher than those after the first immunization. Regardless of primary immunization or secondary immunization, the GMTs (log2) of HAV antibodies in the test vaccine groups with doses of 160 EU/dose and above were higher than those in the 80 EU/dose group (all P<0.05), while there was no statistically significant differences between the dose groups of 160 EU/dose and above (all P>0.05). The antibody positive conversion rate of 160 EU/dose and above of the test vaccine was 100.00% after the secondary immunization.
Conclusions
The inactivated hepatitis A vaccine of attenuated H2 strain tested in this study demonstrates strong immunogenicity in mice, suggesting its potential as a candidate vaccine. The preliminary analysis indicates an immunizing dose of 320 EU/dose for children and 640 EU/dose for adults.

Objective To evaluate the protective effect of hydrogen-rich saline on renal ischemia/reperfusion (I/R) in mice. Methods Thirty C57BL/6 mice were randomly divided into 3 groups: sham-operated (SO) group, I/R group (mice were injected with 5 ml/kg saline by tail vein just before ischemia induction) and hydrogen-rich saline group (mice were injected with 5 ml/kg hydrogen-rich saline). At the 6th h after reperfusion, the sera and renal samples subject to IR injury were collected. The Scr and BUN levels in serum were determined and renal histological changes were also examined. The apoptosis of renal tubular epithelial cells was measured by terminal deoxynucleotidyl transferase mediated dUTP nick end labeling assay. Malondialdehyde (MDA) contents in renal samples were measured using specific kits. The infiltration of F4/80 positive macrophages and neutrophils was assayed by using immunohistochemistry. The mRNA expression of TNF-α, IL-6, IL-1β and IL-17 was detected by using real time reverse transcription PCR. Results As compared with LR group, at the 6th h following reperfusion the levels of Scr and BUN were significantly reduced (P<0.05), histological changes obviously alleviated (P<0.01), apoptosis of renal tubular epithelial cells and MDA contents was decreased (P<0.05) in hydrogen-rich saline group. Moreover, the infiltration of macrophages and neutrophils, and the mRNA expression of TNF-α, IL-6, IL-1β and IL-17 in renal tissue in hydrogen-rich saline group were also declined as compared with IR group (P<0.05). Conclusion Hydrogen-rich saline can ameliorate renal IR injury to some extent, which is associated with inhibition of inflammatory response induced by reperfusion.
