Objective To investigate the clinical efficacy of sildenafil in treatment of pulmonary arterial hypertension (PH),in order to provide more theory basis for clinical treatment.Methods A total of 80 PH patients was enrolled in this study.All the 80 cases were divided into conventional treatment group and sildenafil treatment group with 40 cases each.The 6-min walk test distance,Brog dyspnea score,pulmonary artery systolic pressure(SPAP),heart rate,circulation systolic blood pressure (cSBP),circulation diastolic blood pressure (cDBP),alanine aminotransferase (ALT),aspartate aminotransferase (AST),blood urea nitrogen (BUN) and serum creatinine (SCr) were recorded before and after treatment.The clinical efficacy was compared between two groups.Results The 6-min walk test distance,Brog dyspnea score and SPAP before treatment in conventional treatment group and sildenafil treatment group were (258.62 ±58.34),(260.22 ± 54.33) m; (3.2 ± 1.1),(3.3 ± 1.2) scores; (70.66 ± 6.52),(71.09 ± 6.61) mm Hg (1 mm Hg =0.133 kPa),and there was no significant difference between two groups (P ＞ 0.05).The 6-min walk test distance was (332.67 ± 63.51),(411.47 ± 75.86) m after treatment in conventional treatment group and sildenalil treatment group,which was increased compared with that before treatment (P ＜ 0.05).Brog dyspnea score and SPAP were (2.6 ± 0.8),(2.0 ± 0.6) scores and (61.43 ± 5.27),(47.84 ± 5.15) mm Hg after treatment in conventional treatment group and sildenafil treatment group,which were decreased compared with those before treatment (P ＜ 0.05).The improvement of the 6-min walk test distance,Brog dyspnea score and SPAP in sildenafil treatment group were better than those in conventional treatment group (P ＜0.05).There was no significant difference in the heart rate,cSBP,cDBP,ALT,AST,BUN,SCr before and after treatment in two groups (P ＞ 0.05).The total effective rate in sildenafil treatment group was higher than that in conventional treatment group [77.5％ (31/40) vs.57.5％ (23/40)],and there was significant difference (P ＜ 0.05).The side effects were main headache,blushing,dyspepsia.Conclusion Sildenafil has more effective clinical efficacy in treating PH patients with accepted side-effect,which is worthy to be popularized in the clinical application.

Objective To investigate the relationship of sperm morphology with seminal plasma zinc and sperm acrosin activity in male infertile patients.Methods 455 patients with male infertility were divided into 5 groups and 8 groups according to age and sperm morphology respectively.The sperm morphology,seminal plasma zinc and sperm acrosin activity were detected by the Diff-Quik stain,modified 5-Br-PAPS and modified Kennedy methods respectively.Results The percentages of morphologically normal sperm and seminal plasma zinc concentration in the infertile men groups were not different in various age groups(P >0.05 ).The sperm acrosin activity in the age group of 36-50 years was remarkably decreased (P <0.05),while which in other age groups had no statistical difference(P >0.05).Seminal plasma zinc concentration in the infertile men groups were not different in the 8 groups (P >0.05 ).Sperm acrosin activity was decreased with the percentage decrease of morphologically normal sperm (r =0.93,P <0.01).Conclusion The percentage of morphologically normal sperm is not affectd by the age and the seminal plasma zinc,which is positively correlated with the sperm acrosin activity.

An HA-1-DC nucleic-acid vaccine was constructed to induce anti-leukemia effect after hematopoietic stem cell transplantation (HSCT). DCs were generated from HSCT donors in vitro, and its immunologic activity was assayed by using flow cytometry and mixed lymphocytes reaction. HA-1 gene was electroporated into the cultured DCs to construct a DC nucleic-acid vaccine. After transfection for 48 h, the expression of HA-1 protein could be detected by using Western blot. The DCs were cultured with syngenic lymphocytes to induce specific cytotoxic T lymphocytes (CTLs). The cytoxicity of the CTLs was detected by LDH assay. The results showed that The DCs derived from peripheral blood monocytes (PBMCs) expressed the phenotype of DCs, and were effective in stimulating proliferation of the allogenic lymphocytes. After electroporating for 48-h, HA-1 protein was detected by using Western blot. The cytotoxicty of inducing CTLs was higher than the control group. It was suggested that minor histocompatibility antigen HA-1 could be considered as a target of immunotherapy against leukemia after HSCT.

OBJECTIVEWe sought to master the clinical characteristics and prognosis of hard mental lung disease, improving this disease's diagnosis and treatment quality.

METHODSWe recruited two suspected patients with hard mental lung disease and collected their occupational history, examination results of occupational health, and past medical records. By virtue of laboratory tests, high Kv chest radiography, CT and HRCT of chest, fiberoptic bronchoscopy and ECG examination, diagnostic report was synthesized respectively by respiratory physicians and pathologist from three different agencies. Then the report was submitted to diagnosis organizations of occupational disease, and diagnostic conclusion of occupational disease was drawn after discussion by at least three diagnosticians of occupational disease.

RESULTSWe found that both of the two suspected patients were exposed to dusts of hard metal, and length of exposure service ranged from 8 to 9 years. Clinical manifestations were dominated by dry cough, wheezing after activities, and pathological manifestation was characteristic giant cell interstitial pneumonia. The prognosis and outcome of the disease were different.

CONCLUSIONAccording to exact occupational exposure history, clinical manifestations, combined with the results of high Kv chest radiography, CT of chest and pathological manifestation, it can be diagnosed with hard mental lung disease.

Objective To explore the effect of exercise preconditioning on inflammatory response in ischemic stroke brain tissue which mediated by miR-146a in extracellular vesicles in rats with middle cerebral artery oc-clusion(MCAO),and its mechanism.Methods Sixty 6-week-old male Sprague-Dawley rats were randomly divid-ed into a non-exercise group and an exercise group.The non-exercise group was further divided into a sham-operation control group(C,n=15)and an MCAO model group(M,n=15),while the exercise group was further di-vided into an exercise only group(E,n=15)and an exercise plus MCAO model group(EM,n=15).Rats in the E and EM groups underwent 8 weeks of treadmill exercise,6 days per week,30 minutes per day.Then rats in the M and EM groups received MCAO to induce ischemic stroke,while the C and E groups underwent a sham surgery.Twenty-four hours after the surgery,neurobehavioral tests were performed.Plasma was collected to ex-tract extracellular vesicles,and brain tissue was collected to measure the volume of cerebral infarction by using the triphenyl tetrazolium chloride(TTC)staining.Moreover,the Nissl staining was conducted to observe neuronal and Nissl body.Mean while,the content of miR-146a in plasma extracellular vesicles and brain tissue was mea-sured by using the quantitative polymerase chain reaction(qPCR),and the expression of TNF receptor associat-ed factor 6(TRAF6),nuclear factor kappa-B(NF-κB)and tumor necrosis factor-α(TNF-α)in brain tissues were determined using Western blotting.The targeting relationship between miR-146a and TRAF6 was detected by using the dual luciferase reporter gene assay.Results(1)The neurological behavioral scores of the EM and M groups were higher than those of the C group(P<0.01 and P<0.01),with that of the EM group lower than the M group(P<0.01).(2)TTC staining showed that the infarct volume of the EM and M groups was larger than that of the other two groups(P<0.01 and P<0.01),with that of the EM group smaller than the M group(P<0.01).(3)Nissl staining results showed that the neuronal arrangement was loose,the number of neurons re-duced,and the Nissl bodies were lightly stained and decreased in the M group compared with the C and E groups.Moreover,compared with the M group,the number of neurons and Nissl bodies increased in the EM group.(4)The qPCR analysis showed that the expression of miR-146a in the plasma-derived exosomes and brain tissues of the EM and M groups decreased compared with the C group(P<0.05 and P<0.01),with that of the EM group higher than the M group(P<0.05).(5)According to Western blotting,compared with the C group,the expression levels of TRAF6,NF-κB,and TNF-α proteins increased significantly(P<0.05 and P<0.01),with that of group EM signfiicantly lower than group M(P<0.05 and P<0.05).(6)Dual-luciferase report-er gene assay showed that miR-146a had a specific binding site with TRAF6.Conclusion Eight weeks of exer-cise preconditioning reduces the infarct area and the extent of brain damage,which may be mediated by miR-146a via exosomes,increasing the expression of miR-146a in brain tissue,targeting TRAF6,negatively regulat-ing TRAF6/NF-κB,and reducing the expression of TNF-α,thus alleviating the inflammatory response in brain tissue and exerting a protective effect on ischemic brain injury.

Objective To assess the factors associated with the restoration of spontaneous circulation (ROSC) and 2-year survival prognosis in patients with cardiac arrest (CA) after acute myocardial infarction (AMI),and after ROSC,the effects of various factors on midian survival time and on 2-year survival.Methods In a registry study from January 2005 to January 2015,all consecutive AMI-induced CA patients treated with cardiopulmonary resuscitation (CPR) admitted to our hospital were enrolled.The survivors were followed-up for 2 years.Univariate analysis was applied to evaluate factors associated with rate of ROSC and 2-year survival.Multivariable logistic regression analysis was applied to evaluate statistically significant factors in the univariate analysis.Medians with inter-quartile ranges were used to describe 2-year survival time affected by various factors after ROSC.Kaplan-Meier survival curve analysis was used to evaluate the effect of factors on 2-year survival.Results A total of 254 cases with CA after AMI were enrolled,including 129 cases of ROSC and 71 cases of 2-year survival.Univariate analysis showed age ≥ 70 years,CA occurred during 22:00-8:00,the duration time ofCPR ≥ 15 min and adrenaline dosage ＞ 5 mg were unfavorable predictors of ROSC;while,left ventricular ejection fraction (LVEF) ≥ 40％ before CA,shockable rhythm and percutaneous coronary intervention (PCI) therapy were favorable predictors.Besides,age ≥ 70 years,intubation during CPR,adrenaline dosage ＞ 5 mg and cardiogenic shock were unfavorable predictors of 2-year survival;While,male,normal daily activity before CA and PCI treatment were favorable predictors.Multivariable analysis showed age,the duration of CPR,adrenaline dosage,LVEF before CA,the rhythm during CPR and PCI therapy were independent predictors of ROSC.Age and PCI therapy were independent predictors of 2-year survival.Among patients,the survival time was affected by various factors after ROSC,and the factors with minimum 25％ and small median value were associated with cardiac rupture,cancer,adrenaline dosage ＞ 5 mg and cardiogenic shock.The factor with maximum 25％ value was PCI treatment (216 days).Kaplan-Meier survival analysis suggested that age ≥ 70 years was an unfavorable factor of 2-years survival (Log-rank test,P=0.007);while,PCI treatment was a favorable factor (Log-rank test,P＜0.01).PCI-related prognosis analysis showed that the effectiveness of PCI was related to the timing of PCI,the number of infarctrelated artery and the difference in culprit lesion.Conclusions The age ≥ 70 years was disadvantageous to both ROSC and 2-year survival.PCI treatment was favorable to both ROSC and 2-year survival.
