RESUMO

Rare diseases have been a major challenge for clinical medicine and public health challenge in China. One of the effective measures is to conduct proactive research on rare diseases to deal with the disease burden of the diseases. However, low prevalence, disperse distribution of patients, lack of knowledge about the disease course, and phenotype heterogeneity hamper the development of research for rare diseases. Recently, it has been found that patients registry is effective in understanding the course of the disease and accu- mulating the cases and data of clinical research or clinical trial design. At present, most of developed countries or regions in the world have promoted clinical research and clinical trials of new medications on rare diseases by using the registration of rare disease. In 2016, Peking Union Medical College Hospital established China's first registry system at the national level-National Rare Disease Registry System of China(NRDRS). NRDRS has accumulated 68 137 cases data registered by the researchers from China's 101 collaborating hospitals in 29 provinces/municipalities/autonomous regions, covering 171 different, and forming 188 cohorts. To date, NRDRS complete the initial stage of resources buildup.Nex stage will be focused on clinical research and clinical trials related to rare diseases based on NRDRS. This article is on the process of building NRDRS, the potential support for conducting clinical research and clinical trials related to rare diseases, and the challenges will be faced.

RESUMO

Objective@#To assess the efficacy and safety of thrombolytic treatment with reteplase in patients with intermediate-risk acute pulmonary embolism.@*Methods@#Ten consecutive patients with intermediate-risk acute pulmonary embolism who received thrombolytic treatment with reteplase at Thrombosis and Vascular Medicine Center, Fuwai Hospital from March to November in 2016 were included.Vital signs, right ventricular diameter, systolic pulmonary artery pressure, and biochemical markers were assessed before and after thrombolytic therapy with reteplase, and bleeding complications were also observed during 3 months follow up.@*Results@#(1) For the efficacy outcomes: at 48 hours after thrombolytic treatment with reteplase, echocardiography-derived diameter of right ventricular was significant reduced from (27.9±3.8) mm to (24.8±2.6) mm (P=0.03), systolic pulmonary artery pressure decreased from (63.9±21.6) mmHg(1 mmHg=0.133 kPa) to (34.4±19.8) mmHg (P=0.02). Heart rate and breathing rate were also decreased significantly (both P<0.05), blood pressure remained unchanged post therapy.Hypoxemia was quickly corrected with an significant elevation of PaO2 and SaO2 ((65.2±14.3) mmHg vs. (80.0±9.6) mmHg, P=0.006; (90.8±3.5)% vs. (95.2 ±1.6)%, P=0.002 respectively). PaCO2 was also increased significantly (P<0.05). Serum NT-proBNP and cTnI were decreased significantly (both P<0.05). There was no recurrent pulmonary embolism or deep-vein thrombosis during the 3 months follow-up. (2) For the safety outcomes: a thrombolytic relevant hemoptysis (about 70 ml) occurred in 1 patient, and was controlled by PCC therapy.No other clinically relevant events were observed during thrombolytic treatment. Eight patients were followed more than 3 months, there was no major bleeding complication or death during the follow up period.@*Conclusion@#Treatment of intermediate-risk acute pulmonary embolism with reteplase is effective and safe and there are no obvious side effects.

RESUMO

Objective: To summarize the peri-operative management experience of pulmonary endarterectomy (PEA) in patients with chronic thromboembolic pulmonary hypertension (CTEPH). Methods: A total of 56 CTEPH patients received PEA in our hospital from 2015-01 to 2016-11 were retrospectively analyzed. Our study was focused on the medication in respiratory and circulatory system during ICU stay, peri-operative application of vasoactive drug and target drug to pulmonary hypertension (HP), usage of ventilators, mechanical assisted devices and other management experiences. Results: No peri-operative death occurred. There were 2/56 (3.6%) patients with lung reperfusion, 2 (3.6%) with PH crisis. Compared with pre-operation, the post-operative pulmonary artery hemodynamics parameters were improved as right heart catheter measured pulmonary artery systolic pressure (PASP) decreased from (85.05±22.40) mmHg to (36.83 ±17.21) mmHg and pulmonary vascular resistance decreased from (773.84±342.95) dyn·s·cm-5 to (293.59±214.95) dyn·s·cm-5. Post-operative oxygen saturation was maintained at (95-100) % in all patients. Echocardiography found that PASP from pre-operation (85.03±25.78) mmHg decreased to (39.44±19.24) mmHg at follow-up period, P<0.01.Conclusion: A comprehensive peri-operative management of PEA was helpful to improve pulmonary hemodynamics in CTEPH patients; meanwhile, effective prevention and treatment of severe complication could obviously reduce peri-operative mortality.

RESUMO

Objective@#To establish a hydrogen peroxide (H2O2) induced injury model of pulmonary artery endothelial cells (PAECs) and explore the molecular mechanisms of oxidative stress on the structure and function of PAECs in this model.@*Methods@#Human PAECs were treated with H2O2 at different concentrations (25, 50, 100, 200, 400, 800, 1 600, 3 200, 6 400 μmol/L) for 4 and 24 h, respectively. The PAECs survival curve was obtained according to the cell viability measured by CCK-8 assay. The cell apoptosis of PAECs was detected by flow cytometry. The reactive oxygen species (ROS) generation and mitochondrial activity were measured using small molecule fluorescent probes. Proteins were extracted and the phosphorylation levels of signal molecules in PAECs were detected by Western blot assays.@*Results@#(1) The effect of H2O2 at various concentrations on cell viability of PAECs: cell viability of PAECs decreased in proportion to increasing concentration of H2O2 after incubation for 4 h. The half maximal inhibitory concentration (IC50) of PAECs exposed to H2O2 for 4 and 24 h were 397.00 and 488.77 μmol/L, respectively. (2) The effect of H2O2 on cell apoptosis of PAECs: After H2O2 incubation for 4 h, proportions of PAECs at late-apoptosis ((22.58±3.69) %) and necrotic stage( (11.86±4.27)%) were significantly higher than those of control PAECs at late-apoptosis stage( (3.41±1.44)%, P<0.01) and at necrotic stage ((1.94±1.15) % , P<0.05). The survival rate of PAECs post H2O2 was dramatically lower than that of control PAECs ((7.98±3.21)% vs. (48.89±8.08)%, P<0.01). However, there is no statistical difference between both groups regarding to the early apoptosis. (3) The effect of H2O2 on mitochondrial activity and ROS production of PAECs: the mitochondrial activity and ROS generation of PAECs treated by H2O2 were significantly increased compared to those in control PAECs (P<0.01). (4) The effect of H2O2 on signaling molecules in PAECs: there was a significant increase in phosphorylation level of Akt in PAECs incubated with H2O2 for 30 minutes compared to that in control PAECs (P<0.01), while there was no significant difference in levels of Akt between H2O2 treated PAECs and control PAECs. Phosphorylation level of JNK as well as p38 were also significantly upregulated in H2O2 treated PAECs (P<0.01).@*Conclusion@#H2O2 at the concentration of 400 μmol/L could induce human PAECs injuries via the regulation of Akt and MAPK signaling pathways.

RESUMO

Objective To explore the characteristics and survival of connective tissue disease (CTD) patients with both of pulmonary arterial hypertension (PAH) arnd interstitial lung disease (ILD),and to compare with CTD patients with isolated PAH.Methods All adult CTD patients who visited one of the three referral centers in China with a diagnosis of PAH confirmed by right heart catheterization from July 2006 to May 2011 were enrolled.They were then divided into two groups (ILD with and without-ILD group) based on chest CT and then the comparison of baseline characteristics and survival at the endpoint of follow up were made between the two groups.T test,Mann-Whitney U test,x2 test,Kaplan-Meier survival analysis and Cox regression analysis were used for statistical analyses.Results One hundred and twenty-six patients were recruited into the study.Patients with ILD (n=27) were older than those without ILD (n=99).Lung function results including FVC [(75±18)% vs (83±13)%,t=2.212,P=0.037] and DLCO [(54±22)% vs (68±20)%,t=2.392,P=0.019] in ILD group were significantly wose than those without-ILD group.Although some important hemodynamic parameters such as mean pulmonary arterial pressure and pulmonary vascular resistance were better in the ILD group than the without-ILD group,Kaplan-Meier analysis showed that the short term survival of ILD group was significantly worse than that of the without-ILD group (72.7% versus 94.7% at 1 year and 63.6% versus 81.1% at 3 year,P=0.047).In ILD group,Cox regression analysis showed that SvO2 was the only independent factor for the short term survival [HR=0.19,95%CI (0.04,0.83),P=0.027],and Kaplan-Meier analysis showed patients with SvO2<60% had significantly lower short term survival than patients with SvO2 ≥60% (1 and 2 year survival were 60.0% and 40.0% versus 92.9% and 77.4% respectively,P=0.002).Conclusion Patients with both PAH and ILD is a special subtype in CTD.Although with the superiority of hemodynamics,these patients have significantly worse survival than CTD patients with isolated PAH.Low SvO2 is the independent risk factor for the short term mortality in patients of CTD complicated by both PAH and ILD.More attention should be paid to these patients and the management strategy should be investigated further.

RESUMO

<p><b>OBJECTIVE</b>To evaluate the association between homocysteine level and prethrombotic status and long-term thromboembolic events in patients with primary hypertension.</p><p><b>METHODS</b>Results between 110 hypertensive patients with elevated homocysteine (HCY) level were compared with 110 hypertensive patients with normal HCY level which were enrolled from October 2003 to November 2009. Fibrinogen (FIB), viscosity, thrombomodulin (TM), granule membrane protein (GMP-140), prethrombin F1+2 fragment (F1+2), D-dimer fragment (D-Dimer) and antithrombin III (AT-III) were measured and correlated to HCY and prethrombotic state. The endpoints of the study were arterial and venous thromboembolic events. The variables linked with arterial and venous thromboembolic events were included in Cox proportional hazard models. The event-free survival was illustrated with Kaplan-Meier survival curves and compared by the Log-rank test.</p><p><b>RESULTS</b>The patients were followed up for 8-122 months (median follow-up time was 85 months). Compared with hypertensive patients with normal HCY, the plasma level of TM ((4.8±1.2) µg/L vs. (4.5±1.0) µg/L, P = 0.045), GMP-140 ((18.8±3.2) µg/L vs. (17.1±4.3) µg/L, P = 0.001), F1+2 ((1.2±0.4) nmol/L vs. (1.0±0.6) nmol/L, P = 0.004) were significantly higher while the plasma level of AT-III ((95.3±10.4) % vs. (98.6±10.6)%, P = 0.021) was significantly lower in hypertensive patients with elevated HCY level. FIB, viscosity of plasma and D-dimer were similar between the two groups. Multiple regression analyses indicated that HCY level was negatively correlated with AT-III (β = -0.199, P = 0.011) and positively correlated with age (β = 0.217, P = 0.04), female gender (β = 5.667, P = 0.001) and TM (β = 2.341, P = 0.003). Cox multivariate analysis revealed that age and HCY level were independent prognostic risk factors of thromboembolic events (OR 1.046, 95% CI 1.013-1.082, OR 1.052, 95% CI 1.027-1.078, respectively) (all P < 0.05). Kaplan-Meier curves showed that there was a significant difference in the event-free survival between the two groups (Log-rank test, P = 0.027).</p><p><b>CONCLUSIONS</b>Compared with normal HCY hypertensive patients, the levels of plasma prothrombin activators such as TM, GMP-140 and F1+2 were significant increased and anti-thrombin factor such as AT-III was significant decreased in hypertensive patients with elevated HCY. Old age and high HCY level were independent prognostic risk factors of thromboembolic events. The event-free survival in hypertensive patients with elevated HCY is lower than in hypertensive patients with normal HCY level.</p>

RESUMO

<p><b>OBJECTIVE</b>To explore the baseline clinical characteristics of patients with pulmonary arterial hypertension after operation for congenital heart disease (AO-CHD-PAH) in China.</p><p><b>METHODS</b>A total of 122 consecutive patients diagnosed as AO-CHD-PAH in Shanghai Pulmonary Hospital from September 1, 2006 to August 31, 2011 were retrospective analyzed.</p><p><b>RESULTS</b>Sixty-seven percent patients were female. The median age at procedure and diagnosis were 14.8 and 24.8 years old, respectively. The median duration from procedure of CHD to diagnosis of PAH was 7.3 years. The most frequent initial symptom (109/122, 89.3%) attributed to PAH was dyspnea on exertion. The frequent sign was accentuation of second heart sound on pulmonary valve area (113/122, 92.6%).Incidence of WHO functional PAH classes I/II was 53.3% (65/122) and mean 6 minutes walk distance was limited to (408.4 ± 103.3) m. Borg dyspnea score was 2.0 (1.0, 3.0).Right heart catheterization demonstrated severe elevated mean pulmonary arterial pressure [(71.6 ± 24.2) mmHg, 1 mmHg = 0.133 kPa] and pulmonary vascular resistance index [(29.1 ± 16.0) Wood U·m(2)] in this patient cohort. Cardiac index was (2.7 ± 0.9) L·min(-1)·m(-2), 90.2% (110/122) patients received PAH-specific therapy. The majority of PAH-specific therapy was phosphodiesterase type 5 inhibitor, which is somehow different from PAH-specific therapy regimen of American-European developed countries.</p><p><b>CONCLUSIONS</b>PAH-specific therapy rate is satisfactory for pulmonary arterial hypertension after operation for congenital heart disease in China and phosphodiesterase type 5 inhibitors are predominant PAH-specific medication in China.</p>

RESUMO

<p><b>OBJECTIVE</b>To compare the clinical characteristics and survival on Chinese patients with idiopathic pulmonary arterial hypertension (IPAH) and familiar pulmonary arterial hypertension (FPAH) during conventional therapy era and targeted therapy era.</p><p><b>METHODS</b>IPAH and FPAH patients who were referred between Jan 1999 and Oct 2004 in Fuwai Hospital were defined as conventional therapy era group (before 2005 no PAH-specific drug was available in China). All patients in this group were followed up till Jun 2005. IPAH and FPAH patients who were referred between Sep 2006 and Aug 2011 were defined as targeted therapy era group (new PAH-specific drugs were available in China since 2006) were analyzed. All patients in this group were followed up till Dec 2013. The primary endpoints were death and therapy medicine.</p><p><b>RESULTS</b>Seventy-two patients were enrolled in conventional therapy era group, 375 were enrolled in targeted therapy era group. The mean age was (35.9 ± 12.2) years and (34.5 ± 17.4) years respectively (P = 0.67), and women was predominant in both groups. There was no difference in WHO functional class and hemodynamic data between the two groups. About 90.3% patients were treated by calcium-channel blockers (CCB) in conventional therapy era group. In targeted therapy era group, almost all patients were treated by at least one PAH-specific drug, only 3.2% patients who had a positive response to acute pulmonary vasodilator testing were treated by CCB. The median survival time was 30.4 months in conventional therapy era group and 66.2 months in targeted therapy era group. The 1-, 2-, 3- and 5- year survival rates of IPAH and FPAH patients were 68.0%, 56.9%, 38.9% and 20.8% in conventional therapy era group, and 89.3%, 78.1%, 68.2% and 53.7% in targeted therapy era group respectively (P < 0.000 1).</p><p><b>CONCLUSION</b>Compared with conventional therapy era, the survival rate of Chinese IPAH and FPAH patients is significantly improved in targeted therapy era.</p>

RESUMO

Objective To investigate the intra- and interobserver repeatability of coronary artery disease (CAD) diagnosis based on invasive coronary angiography (ICA) and CT coronary angiography (CTCA).Methods Two readers with comparable experience ( over 10 years) independently evaluated ICA results of 42 consecutive patients with a blind method. After 30 days,one of them reviewed the same patients again.Another two comparable-experience (over 10 years) readers evaluated the results of CTCA (prospectively ECG-triggering) from the same 42 patients in the same way.The inter-reader and intra-reader repeatability of ICA and CTCA were analyzed by performing Kappa test and calculating the percentage of the segments with agreement on stenotic degree.Using ICA as reference,the accuracy of CTCA in diagnosing CAD was studied by comparing the area under ROC. Results The Kappa between readers for ICA and CTCA were 0.91 and 0.81.Intra-reader Kappa were 0.92 and 0.83 respectively (x2 =509.4 and 432.5,all P <0.01 ).The percentage of the segments with agreement between readers on the degree of stenosis were 80.8% (494/611) in ICA and 75.2% (469/624) in CTCA ( x2 =2.75,P =0.10),and within the same reader,86.9% (531/611)in ICA and 81.9% (511/624) in CTCA(x2 =3.76,P =0.053).With≥ 50%narrowing as a CAD diagnosis criterion,the agreement rates for two readers were 96.6% (590/611 ) in ICA and 94.4% (589/624) in CTCA( x2 =3.36,P =0.07),and for the same reader,97.4% (595/611) in ICA,95.4% (595/624) in CTCA ( x2 =3.62,P =0.06).Using ICA as reference,two readers of CTCA results achieved a sensitivity and specificity of 84.9% (530/624)and 98.1% (612/624).The area under ROC was 0.94 (95% CI 0.91-0.97).Conclusions Both ICA and CTCA demonstrate good repeatability in diagnosing CAD.The repeatability of ICA is superior to that of CTCA.A certain discrepancy exists in two readings from the same reader or two readers.
