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 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 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 investigate the clinical significance of dendritic cell(DC) infiltration and molecules expression in gastric cancer.Methods:After tumor mass was digested by enzyme and cells were seperated,anti S 100 protein antibody immunohistochemical staining and flow cytometric analysis were done in 15 cases of gastric cancer.Reverse transcription polymerase chain reaction(RT PCR)was used to detect IL 10,VEGF and TGF ? 1 mRNA expression in gastric cancer cells.Results:The number of DC in gastric cancer was just small, and correlated reversely with pathologic stages.The levels of some surface molecules expression such as MHC class Ⅱ, costimulatory molecules B7 1 and ICAM 1 in gastric cancer were negative.The number of DC and the levels of some surface molecules expression in gastric cancer were correlated reversely with pathologic stages.Levels of IL 10,VEGF and TGF ? 1 mRNA expression in gastric cancer cells were high.Conclusion:The results indicate that infiltration and surface molecules expression in gastric cancer are closely linked to tumor pathologic stages.

Objective: To investigate the clinical efficacy of acupuncture combined with tuina in treating patients with cervical vertigo. ＜br> Methods: According to the principle of randomization, 258 cases with cervical vertigo who met the inclusion criteria for the study were randomly divided into an observation group and a control group, with 129 cases in each. The patients in the observation group received acupuncture combined with tuina therapy, while those in the control group were just treated by the same acupuncture therapy as in the observation group. After 10-day continuous treatments, the clinical efficacies of the two groups were analyzed and compared. ＜br> Results: The total effective rate of the observation group was 100%, versus 86.0% of the control group, and the difference was significant (P＜0.05). After treatment, cervical range of motion (ROM) scores in both groups were statistically significantly different from those before treatment (allP＜0.05); in addition, there was a statistically significant difference in inter-group comparison of ROM score (P＜0.05). ＜br> Conclusion: Compared with simple acupuncture treatment, acupuncture combined with tuina therapy has a better effect in improving the ROM of cervical vertigo patients, with higher clinical efficacy.

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 study the effect of serf-designed multi-organ preservation solution(SMO)on cold-stored rat liver.Methods The rat livers were preserved with SMO solution(group A,n=15),UW solution(group B,n=15)and HC-A solution(group C,n=15),respectively.The livers were transplanted orthotopically after 6-,12-,24-hour preservation.The changes of liver function at hour 12 after transplantation were detected and conditions of the survived rats at day 14 after transplantation were observed.Results There was no morphological change of the livers in group A within 24 houm.The total bilimbin,alaninetransaminase,and hyaluronic acid increased in group A and B as the preservation time increased,but the levels of the 3 indexes of group A were significant lower than those in group C(F=49.027,70.280,34.349,71.532,446.544,303.408,P＜0.05).No rat djed in group A 14 days after liver transplantation.Conclusions SMO and UW solution have similar effect on protecting the liver.and the protective effect of the 2 solutioas was better than that of HC-A solution.

Objective To study the effects of Sinomenine on the dendritic cells after hepatic ischemia-reperfusion. Methods Forty-eight BN rats were equally divided into control group, low dose (40 μg/g) and high dose (80 μg/g) of Sinomenine groups after the liver transplantation models were established by two cuff tech-nique. Three days after the orthotopic liver transplantation, the livers were resected, then the dendritic cells were separated and purified. The phenotypes [OX62, major histocompatibility complex Ⅱ (MHC-Ⅱ) and CD86] of dendritic cells were examined by FACS, the expression of IL-12, IL-1, and TNF-a mRNA by RT-PCR, and the expression of Toll-like receptor 4 (TLR4) by Western blot. Results The dendritic cells treated with Sinomenine showed immature phenotypes. The expressions of MHC-Ⅱ and CD86 were significantly deceased. The expressions of IL-12, IL-1, TNF-a mRNA and TLR4 were low. Conclusions Sinomenine can significantly inhibit the maturity and immunologic function of dendritic cells after hepatic ischemia-reperfusion.
