Objective To explore the correlation between the expression of IL-17A and the degree of spleen damage in acute mouse cytomegalovirus(MCMV) disseminated infection in vivo and to understand the mechanism about how IL-17A involved in the pathological damage of the spleen in MCMV infection.Methods An acute disseminated MCMV infection model was established in mice.BALB/c mice were randomly divided into two groups.Mice in group one were infected with MCMV Smith to establish disseminated infection.Mice in another group were sham-infected control.Three mice from each group were randomly chosen to be sacrificed on days 3,7,14 and 28 after the infection.Viral titers in spleen tissues were determined using a standard plaque assay.The expression of IL-17A mRNA and MCMV mRNA in the splenocytes were measured by RT-PCR.The expression of IL-17A in spleen tissues was observed by immunohistochemical staining.The pathology of the infected mice was assessed by histological examination of H&E stained spleen sections.Results Viral titers and MCMV mRNA in the spleen peaked on day 3,but quickly diminished on day 7.Virus was no longer detectable in the spleen on day 14 after the infection.The expression of IL-17A mRNA was significantly increased during the acute infection and reached the highest level on day 14,then decreased on day 28.It is significantly higher than that of the mock infection group.Immunohistochemistry assay also indicated that the expression of IL-17A in spleen tissue gradually increased to climax on day 14,then decreased on day 28.Accordingly,the pathological damages of spleen tissue in the infected mice deteriorated until day 14,then showed signs of recovery on day 28.The most severe pathological injury of spleen tissue and the highest expression of IL-17A appeared in the same period of time.Conclusion Our results showed a close correlation between IL-17A and the pathological damage in spleen.Thus,IL-17A may contribute to the spleen pathological damage during the acute disseminated MCMV infection.

Objective To observe the efficacy of antithrombotic treatment of acute ST-segment elevation myocardial infarction patients with failure primary percutaneous coronary intervention because of high thrombus burden,and its effect on elective percutaneous coronary intervention.Methods Eight acute ST-segment elevation myocardial infarction patients were enrolled,who suffered from failure of primary percutaneous coronary intervention because of high thrombus burden.Summarize the antithrombotic strategies in perioperative and postoperative period,the operative strategies and the follow-up coronary intervention were recorded and reviewed.Results All the patients were male and most of them had acute inferior myocardial infarction with right coronary occluded because of high thrombus burden.Four patients received thrombus aspiration and balloon dilation.One patient received thrombus aspiration and the other three patients did not receive coronary intervention.Tirofiban were given in perioperative period to all the patients.Low molecular weight heparin was given to 6 patients.Dual antiplatelet therapy was given to 6 patients (aspirin 100 mg/day plus clopidogrel 75 mg/day) and 1 patient required up-titration of aspirin to 200 mg/day.Coronary angiography were repeated (29.00 ± 23.25) days later,and the thrombus in the culprit vessels disappeared in two patients,and coronary stent implantation was performed in three patients.Conclusions The routine antithrombotic strategies play limited roles in thrombus clearance in acute ST segment elevation myocardial infarction patients with failure primary percutaneous coronary intervention because of high thrombus burden.The time for the thrombus to be totally organized and the timing of elective percutaneous coronary intervention are still uncertain and need to be further studied.

Objective To analyze the correlation between internal iliac artery calcification and delayed graft function (DGF) and short-term prognosis of kidney transplant recipients. Methods Clinical data of 222 kidney transplant recipients were retrospectively analyzed. According to the recovery of renal function, all recipients were divided into the DGF group (

Objective To elucidate activity of baicalin against human cytomegalovirus ( HCMV) in vitro, and explore its effect on apoptosis of human embryo lung fibroblasts ( HEL ) infected with HCMV. Methods CCK-8 kit was used to determine the maximum tolerated dose ( MTC ) of HEL cell to baicalin while the anti-HCMV median efficacious concentration ( EC50 ) of baicalin was determined by standard plaque reduction method. After treatment with baicalin of different concentrations for 24, 48, 72 and 96 h, cell apoptosis and pro-caspase-3 expression was detected by flow cytometry and Western blotting, respectively. Results The MTC of baicalin was 20.6 μg?mL-1; The EC50 of anti-HCMV of baicalin was 16.13 μg?mL-1;The apoptosis rate increased gradually in the groups with low and high multiplicity HCMV infection at early time, showing significant dose-dependent manner. While the ratio of apoptotic cells was going to decrease in high multiplicity infection group 96 h after the infection. The expression of pro-caspase-3 was significantly higher in high-dose baicalin treatment group than in the infection control group ( P<0.05) . Conclusion Baicalin has a direct anti-HCMV effect in vitro. One of the mechanisms might be related with it inhibiting cell apoptosis and antagonizing activation of pro-caspase-3.

Hypertension is a common cardiovascular disease. Chinese guidelines for the management of hypertension, the global practice guidelines for hypertension of the International Hypertension Society (ISH) and the guidelines for the treatment of adult hypertension drugs of the World Health Organization have been issued successively, which play an important role in guiding the clinical medication of hypertension. Calcium channel blockers (CCB), angiotensin converting enzyme inhibitors (ACEI), angiotensin receptor blockers (ARBs), angiotensin receptor neprilysin inhibitor (ARNI), thiazide diuretics and β-receptor blockers are commonly used in clinical antihypertensive drugs. The goal of hypertension drug control, the application timing of hypertension drugs, the selection of combined medication scheme, the drug selection of hypertension complicated with other diseases, and the medication of gestational hypertension are all problems that clinicians need to master.

Objective To evaluate the survival and prognostic factors of esophageal cancer treated with definitive ( chemo ) radiotherapy by applying novel radiation techniques including three-dimensional conformal radiotherapy (3DCRT) or intensity-modulated radiotherapy (IMRT). Methods Clinical data of 2762 patients with non-operated esophageal squamous cell carcinoma who underwent definitive ( chemo ) radiotherapy from 2002 to 2016 in 10 hospitals were retrospectively analyzed.The prognostic factors were also identified and analyzed. Results The median follow-up time was 60. 8 months. The 1-, 2-, 3-and 5-year overall survival (OS) of all patients was 71. 4%,48. 9%,39. 3%,and 30. 9%,respectively.The 1-,2-,3-and 5-year progression-free survival (PFS) was 59.5%,41.5%,35.2%,and 30%,respectively.The median survival was 23 months.The median time to progression was 17. 2 months.Multivariate analysis demonstrated that age, primary tumor location, clinical stage, tumor target volume, EQD2 and treatment mode were the independent prognostic factors for OS.Primary tumor location,clinical stage,tumor target volume and EQD2 were the independent prognostic factors for PFS. Conclusions In this first large-scale multi-center retrospective analysis of definitive ( chemo) radiotherapy for esophageal squamous cell carcinoma in China, the 5-year OS of patients with esophageal squamous cell carcinoma is significantly improved by 3DCRT, IMRT combined with chemotherapy drugs. However, the findings remain to be validated by prospective clinical trials with high-level medical evidence.
