ABSTRACT
BackgroundA recently developing pneumonia caused by SARS-CoV-2 was originated in Wuhan, China, and has quickly spread across the world. We reported the clinical characteristics of 82 death cases with COVID-19 in a single center. MethodsClinical data on 82 death cases laboratory-confirmed as SARS-CoV-2 infection were obtained from a Wuhan local hospitals electronic medical records according to previously designed standardized data collection forms. ResultsAll patients were local residents of Wuhan, and the great proportion of them were diagnosed as severe illness when admitted. Most of the death cases were male (65.9%). More than half of dead patients were older than 60 years (80.5%) and the median age was 72.5 years. The bulk of death cases had comorbidity (76.8%), including hypertension (56.1%), heart disease (20.7%), diabetes (18.3%), cerebrovascular disease (12.2%), and cancer (7.3%). Respiratory failure remained the leading cause of death (69.5%), following by sepsis syndrome/MOF (28.0%), cardiac failure (14.6%), hemorrhage (6.1%), and renal failure (3.7%). Furthermore, respiratory, cardiac, hemorrhage, hepatic, and renal damage were found in 100%, 89%, 80.5%, 78.0%, and 31.7% of patients, respectively. On the admission, lymphopenia (89.2%), neutrophilia (74.3%), and thrombocytopenia (24.3%) were usually observed. Most patients had a high neutrophil-to-lymphocyte ratio of >5 (94.5%), high systemic immune-inflammation index of >500 (89.2%), increased C-reactive protein level (100%), lactate dehydrogenase (93.2%), and D-dimer (97.1%). A high level of IL-6 (>10 pg/ml) was observed in all detected patients. Median time from initial symptom to death was 15 days (IQR 11-20), and a significant association between aspartate aminotransferase (p=0.002), alanine aminotransferase (p=0.037) and time from initial symptom to death were interestingly observed. ConclusionOlder males with comorbidities are more likely to develop severe disease, even die from SARS-CoV-2 infection. Respiratory failure is the main cause of COVID-19, but either virus itself or cytokine release storm mediated damage to other organ including cardiac, renal, hepatic, and hemorrhage should be taken seriously as well. FundingNo founding. Research in contextO_ST_ABSEvidence before this studyC_ST_ABSAs the seventh member of enveloped RNA coronavirus, severe acute respiratory syndrome coronavirus (SARS-CoV)-2 causes a cluster of severe respiratory disease which is similar to another two fatal coronavirus infection caused by SARS-CoV and Middle Eastern respiratory syndrome coronavirus (MERS-CoV). Through searching PubMed and the China National knowledge infrastructure databases up to February 20, 2020, no published article focusing on hospitalized dead patients was identified. Added value of this studyWe conducted a single-center investigation involving 82 hospitalized death patients with COVID-19 and focused on their epidemiological and clinical characteristics. 66 of 82 (80.5%) of patients were older than 60 years and the median age was 72.5 years. The bulk of death cases had comorbidity (76.8%). Respiratory failure remained the leading cause of death, following by sepsis syndrome/MOF, cardiac failure, hemorrhage, and renal failure. Most patients had a high neutrophil-to-lymphocyte ratio, high systemic immune-inflammation index, and increased levels of proinflammatory cytokines. Implications of all the available evidenceSARS-CoV-2 causes a cluster of severe respiratory illness which is similar to another two fatal coronavirus infection caused by SARS-CoV and MERS-CoV. Death is more likely to occur in older male patients with comorbidity. Infected patients might develop acute respiratory distress and respiratory failure which was the leading cause of death, but damages of other organs and systems, including cardiac, hemorrhage, hepatic, and renal also contribute to the death. These damages might be attributable to indirect cytokines storm initiated by immune system and direct attack from SARS-CoV-2 itself.
ABSTRACT
Objective To explore the safety and feasibility of guiding catheter passing through spasmodic vessels in patients undergoing percutaneous coronary intervention (PCI) via radial artery access by the aid of PCI guiding wire and balloon .Methods The clinical data of 33 coronary artery disease (CAD) patients undergoing PCI via radial artery access with radial artery or (and) brachial artery spasm ( group A ) were retrospectively analyzed .Among all these patients , guiding catheters were delivered through the spasmodic vessels successfully by the aid of PCI guiding wires and balloons .The clinical data of other 38 CAD patients having PCI during the same period performed by other operators via radial artery or ( and ) brachial artery approach and experienced vessel spasm were anlysed as the control ( group B ) .All patients in group B received conventional anti-spasm management during PCI .All vessel spasm was identified by angiography.For patients in group A , a diameter of 0.014 inch guiding wire was chosen to pass through the spasmodic vessel segment carefully and gently .The diameter of balloon should be chosen according to the diameter of guiding catheter .A balloon diameter of 2.0 mm and 2.5 mm was corresponded to 6F and 7F guiding catheter respectively .The balloon was advanced to the tip of guiding catheter , keeping a half in catheter and a half in vessel followed by inflating the balloon with a pressure of 8 atm.The balloon was kept inflated the guiding catheter was pushed in vitro carefully and slowly until the catheter passed through the spasmodic vessel segment .Then the balloon was deflated and pulled out together with PCI guiding wire . Exchanged a diameter of 0.035 inch wire and completed the positioning of guiding catheter .After finishing the PCI, radial or ( and) brachial angiography was performed again to observe if spasm disappeared and to determine if there any contrast medium exudation .For patients in group B , routine approach was applied including administration of nitroglycerine , diltiazem or nitroprusside etc . to relieve vessel spasm. Results The location of vessel spasm was similar in group A and group B ( P=0.150 ) , and the incidence rate of spasm in brachial artery was higher than that in radial artery in both groups .The chance of guiding catheter crossing the spasmodic vessel segment was significantly higher in group A than in group B ( 100%vs.39.5%, P=0.00).In patients whose guiding catheter could pass through the spasmodic vessel segment successfully , time spent in group A was shorter than in group B ( P=0.000 ) .The patient number which time spent was less than five minutes , five to 15 minutes and more than 15 minutes was 30 and 2 ( 90.1%vs.13.3%) , 3 and 7 ( 9.9% vs.46.7%) and 0 and 6 ( 0% vs.40.0%) in group A and in group B respectively.The incidence of forearm hematoma was lower in group A than in group B without statistical difference [6.1%(2/33) vs.18.4%(7/38), P =0.113].Conclusions It is safe and feasible for passing guiding catheter through spasmodic vessels during PCI via radial artery access by the aid of PCI guiding wire and balloon .
ABSTRACT
Objective To explore the accuracy of three dimensional speckle tracking imaging (3D-STI) in quantitative coronary evaluation of (CHD) patients' left ventricular global systolic function.Methods Sixty-eight CHD patients were divided into three groups according to the coronary artery angiography (CAG) results:32 cases in severe stenosis group,23 cases in moderate stenosis group,and 13 cases in mild stenosis group.Thirty gender-age-matched healthy subjects(control group) were enrolled in this study.All patients underwent 2D-echocardiography and real-time three-dimensional echocardiography (3DE).The global longitudinal strain(GLS),global radial strain(GRS),global circumferential strain(GCS),global area strain (GAS),global area strain rate (GASrate) and 3D global LV strain (3D-Strain) were analyzed using 3D-STI.Correlation between strain measurements and left ventricular ejection fraction (LVEF) by simpson method,3D-LVEF by 3DE were assessed using linear regression analysis.Results All 3D-STI parameters in the severe stenosis group were significant decreased compared with the other groups.GLS,GRS,GCS,GAS,3D-Strain of moderate stenosis group shown more significant decrease than both mild stenosis group and control group (P ＜ 0.05).Strong correlations were demonstrated in all 3D-STI parameters between 3D-LVEF and LVEF.The strongest correlation was observed between GAS with 3D-LVEF in severe stenosis group(r =-0.910,P ＜0.05).Intraobserver and interobserver reliability of GAS was better than other parameters.Conclusions Global strain of 3D-STI can quantitatively evaluate the global LV function in CHD patients,and GAS is more sensitive and reproducible than other parameters.

Methods One hundred patients suffering from surgical infection with high fever were randomly divided into two groups: 50 cases in diclofenac group (50 mg with rectal administration) and 50 cases in amidopyrin group (2 ml, with intramuscular injection) , and their antipyretic effects were observed. Results The antipyretic effect of diclofenac (with an overall effective rate of 96% ) was better than that of amidopyrin (82% ), with a P-value less than 0.05, and their remarkably effective rates were 82% and 58% for the two groups, respectively, with a P-value less than P
ABSTRACT
AIM: To observe the curative efficacy of Shenkang Bolt(SKB) in treating chronic renal failure(CRF) with blood silt and damp pathogen syndrome. METHODS: The randomized,parallel and controlled trial were used.38 cases in treatment group were treated with SKB,and 40 cases in control group were clystered with Chinese herbal medicine.The changes of the cumulative scores of traditional Chinese medicine(TCM) syndrome,the levels of serum creatinine(SCr) and creatinine clearance rate(CCr) before and after treatment in both groups were observed. RESULTS: The total effective rate was 81.5% in the treatment group,but 75% in the control group.The scores of TCM syndrome and the levels of SCr were both significantly decreased(P(0.05)). CONCLUSION: SKB can markedly improve the clinical manifestations of CRF with blood silt and damp pathogen syndrome,decrease the levels of SCr,but increase CCr.There was no difference between Chinese herbal clysis and Shenkang Bolt in curative effect,but it is convenent to take Shenkang Bolt.
