Left atrial myxoma is one of the rare causes of cerebral infarction.As the left atrial myxoma complicated artery embolization is more common in cerebral vessels,the first clinical manifestation of about 1/3 patients with left atrial myxoma was cerebral infarction.This article reports a 24-year young female without common vascular risk factors,including hypertension,diabetes,and hyperlipidemia.Multiple cerebral infarctions are the first symptom in patients with left atrial myxoma,and they are analyzed in combination with literature.

Objective To evaluate the association between bradycardia and neurological sequel in patients with restoration of spontaneous circulation (ROSC) after cardiopulmonary resuscitation (CPR) during targeted body temperature management (TTM).Methods Forty-three unconscious patients with ROSC after CPR were treated with TTP.The patients were cooled with therapeutic hypothermia to body temperature target range (32-34°C) after cardiac arrest and divided into bradycardia and control groups depending on the lowest heart rate less than 50 beats/min and more than or equal to 50 beats/min respcetively at that time.The bispectral index (BIS) and the neuron-specific enolase (NSE) values were respectively recorded at the following intervals,0h (h0)、24h (h24)、48h (h48)、72h (h72) after ICU admission.Neurological outcome was defined according to the Pittsburgh cerebral performance category (CPC) at 3 months after ICU discharge.Results Compared with the control group,during TTM the bispectral index levels were significantly higher in the bradycardia group at h0,h48,h72 after admission,(h0 bradycardia group 73.0 ± 12.3;control group 58.0 ± 18.6,P ＜0.01)、(h48 bradycardia group 71.4 ± 21.2;control group 46.3 ± 18.9,P ＜ 0.01)、(h72 bradycardia group 78.6 ± 24.6;control group 51.8 ± 24.1,P =0.01).The neuron-specific enolase level in bradycardia group was significantly lower than that in control group on day3 (118.8 ± 118.8 ng/mL vs.248.3 ± 191.9 ng/mL,P =0.02).The level of CPC in the bradycardia group was significantly higher than that in the control group (P =0.046).Conclusions Patients with bradycardia during TTM had favorable neurological outcome,which could provide evidence for clinical treatment and prognostic evaluation of the patients.

Objective To evaluate the prognostic value of the neuron-specific enolase ( NSE ) and bispectral index ( BIS) in patient with mild therapeutic hypothermia ( MTH) after cardiopulmonary resuscitation ( CPR ) .Methods Forty-six patients with restoration of spontaneous circulation ( ROSC ) after CPR were treated with MTH.The BIS values were recorded and the serum NSE was measured at the following times:24 h, 48 h, and 72 hours after ICU admission.Neurological outcome was classified according to the Pittsburgh cerebral performance category ( CPC 1 to 5) at 3 months after ICU discharge.Results Fourteen patients had a good neurological outcome with CPC score 1-3, and thirty-two patients had a poor neurological outcome with CPC 4-5 at 3 month.Compared with good outcome group, the NSE values were significantly higher in the poor outcome group on day 2 and day 3 after admission [48 h: (90.1 ±42.7) ng/mL vs.(33.2 ±17.5) ng/mL;72 h: (95.4 ±37.0) ng/mL vs. (29.2 ±17.0) ng/mL, P<0.05].NSE increased markedly in the poor neurological outcome group at 48h and 72h, and decreased significantly in the good group at the same time [△NSE 24 h-48 h: (37.3 ±28.7) ng/mL vs.(-10.7 ±12.1) ng/mL; △NSE 48 h-72h: (5.3 ±13.2) ng/mL vs.(-4.0 ±4.5 ng/mL), P<0.05].Over the 72 h of monitoring, the mean BIS values were lower in the poor outcome group compared to the good outcome group at 48 h [ (39.2 ±24.1) vs.(78.0 ±12.4); 72 h: (45.7 ±26.4) vs.(89.0 ±7.3), P<0.05].Conclusions The values of NSE and BIS were effective prognostic indicators for the neurological outcome of patients with MTH after CPR.

BACKGROUND: Recent experimental studies have found ultrasound mediated microbubbles potentiate stem cell therapy in myocardial infarction (MI)-induced heart failure, indicating a good application prospect. But whether ultrasound mediated nitric oxide (NO) microbubbles also have the same effect in the intracoronary transplantation of bone marrow mesenchymal stem cells (BMSCs) for treatment of large animals with MI is still unknown. OBJECTIVE: To investigate the effectiveness and possible mechanism of ultrasound mediated NO microbubbles in potentiating intracoronally transplanted BMSCs homing to the infarcted area in a MI pig model.METHODS: Density gradient centrifugation culture method was used in the isolation and cultivation of BMSCs. CM-Dil was used to label BMSCs in vitro. Twenty-four pigs were used to make MI models by blocking the left anterior descending coronary artery, and then were divided into PBS group, BMSCs group, ultrasound+microbubbles+BMSCs(MB) group, ultrasound+NO microbubbles+BMSCs (NO-MB) group(n=6 per group). In the PBS group, 10 mL of PBS was intracoronally injected. In the BMSCs group, about 1×107 BMSCs were diluted in 10 mL of PBS and then intracoronally infused. In the MB group, 0.1 mL/kg sulphur hexafluoride microbubbles (Sono Vue) was intracoronally injected together with ultrasound treatment (1 MHz, 2 W/cm2, 2 minutes), followed by intracoronary infusion of about 1×107 BMSCs that were diluted in 10 mL of PBS. In the NO-MB group, all methods and conditions were identical to those in the MB group except only 0.1 mL/kg of Sono Vue was replaced by 0.1 mL/kg NO microbubbles. Three pigs were sacrificed in each group 48 hours after CM-Dil positive BMSCs transplantation. The labeled BMSCs were observed and counted by fluorescent microscope after frozen sectioning of the infarct area. We assessed and compared left ventricular systolic function with M-mode ultrasound among groups at 4 weeks after intervention. After cardiac function test, the rest pigs were sacrificed and capillary density in the myocardial ischemic area was counted and compared after hematoxylin-eosin staining. RESULTS AND CONCLUSION: (1) The number of CM-Dil positive cells in the area of MI in the NO-MB group was much more than that in the MB group and BMSCs group with statistical significance (P < 0.05). (2) The left ventricle systolic function was significantly improved in the NO-MB group as compared with the MB group (P < 0.05). The same trend was observed between NO-MB group and BMSCs group as well as between NO-MB group and PBS group (P < 0.05). (3) The density of capillaries increased significantly in the NO-MB group compared with the MB group, BMSCs group and PBS group, respectively. To conclude, ultrasound mediated NO microbubble combined with intracoronary BMSCs transplantation can improve the left ventricular systolic function. The possible mechanism could be that ultrasoundmediated NO mocrobubbles promote the homing of transplanted BMSCs to the myocardial ischemia area as well as improve local angiogenesis.

Objective To investigate the risk factors and outcomes of acute kidney injury (AKI) in patients after intra--coronary stent implantation.Methods A retrospective and case control study was done with data analysis in 325 patients who underwent intra-coronary stent implantation from January 2010 to March 2011.The patients were divided into two groups as per the criteria of AKI identified on the 7th day after implantation of stent.The variables to be studied included:(1) age,gender,hypertension,diabetes,cerebrovascular disease,left ventricular insufficiency,peripheral angiopathy,creatinine,urea nitrogen,estimated glomerular filtration rate,hyperuricemia,proteinuria,emergency operation,hydration,and medication (ACEI/ARB,statins) before operation; (2) dose of contrast media,operation time,hypotension during intra-operative period; and (3) postoperative:hypotension.The variables were analyzed with the process of One-way ANOVA and multivariate Logistical regression analysis.Consequently,the independent risk factors of AKI in patients after intra-coronary stent implantation could be found.Further,the prognosis of AKI patients was analyzed.Results Of the 325 patients,51 (15.7％) developed AKI.Compared the normal group,hospital stay (P ＜ 0.01 ) and in-hospital mortality (P ＜ 0.05) increased significantly in the AKI group.Monofactorial analysis showed that age,pre-operative laboratory and clinical data including left ventricular insufficiency,peripheral angiopathy,creatinine,urea nitrogen,estimated glomerular filtration rate, hyperuricemia, proteinuria, hydration and emergency operation, and intraoperative information such as operation time and hypotension,and postoperative hypotension in AKI patients group were significantly different in comparison with control group ( P ＜ 0.05 ). Multivariate logistic regression analysis revealed that elderly age (OR =0.253),pre-operative proteinuria (OR =5.351 ),preoperative left ventricular insufficiency ( OR =8.704),eGFR ≤ 60 ml/ ( min · 1.73 m2 ) ( OR =6.677 ),prolonged operation time ( OR =1.017),intra-operative hypotension ( OR =25.245 ) were independent risk factors of AKI ( P ＜ 0.05 ).Conclusions AKI is a common complication and associated with increase in mortality after intra-coronary stent implantation.Increase in age,pre-operative proteinuria,pre-operative left ventricular insufficiency,pre-operative low estimated glomerular filtration rate,prolonged operation time,intra-operative hypotension are the independently risk factors associated with AKI.

Objective To determine the power-time-ablation scope correlogram of a water-cooled single needle electrode radiofrequency (RF) ablation system and to establish a theoretical basis for its practical application.Methods RF ablations were performed using a water-cooled single needle electrode radiofrequency ablation system developed by the authors using fresh ox liver as well as liver and muscles of healthy adult New Zealand white rabbits.The temperature of the ablation area was monitored using a multichannel thermometric system.The maximum ablation scope was determined by detecting the rim at which the temperature was no less than 50 °C.The specific absorption rate (SAR) of the isolated liver tissue was calculated.Results In the treatment voltage range of 100-130V,the process was smooth and steady.No impedance variation was obvious.The maximum diameter of a single ablation was 51 cm.With the treatment voltage at 140-170 V,a larger ablation area could be reached in less time,but eventually the impedance began to increase while the ablation area was no longer expanded.When the treatment voltage reached the range of 180-200 V the impedance almost always increased rapidly out of limits,and the treatment system stopped automatically.The measured SAR value was consistent with the theoretical value.Pathology confirmed that both liver tissue and muscle tissue manifested typical coagulative necrosis.Conclusions The power amplifier,cooling,thermometric and control sections of the RF ablation system worked stably,and the practical ablation effect met the design and clinical treatment requirements.

BACKGROUND:Sodium hyaluronate is a polysaccharide polymer biomaterial, which is considered to have a certain effect to repair the cartilage surface, reduce the release of inflammatory mediators, and promote meniscal repair. OBJECTIVE:To observe the therapeutic effect of Fast-Fix combined with sodium hyaluronate in meniscal repair under arthroscope. METHODS:Eighty-six patients with meniscus injury admitted at the Department of Orthopedics, CNPC Central Hospital, from March 2008 to March 2014 were enrol ed in the study. The average age was 25.5 years, and the average duration of disease was 1.5 months. The main clinical manifestations included knee joint pain and swel ing after exercise and positive McMurray signs. The MRI results showed meniscus tear or degeneration. Arthroscopic repairing surgeries were performed with Fast-Fix combined with sodium hyaluronate injection (2.5 mL at the end of surgery), and then sodium hyaluronate was injected intraarticularly at 1, 2, 3 weeks after surgery. Each patient was assessed with Lysholm knee joint score system before and after operation. RESULTS AND CONCLUSION:Eighty-one patients were fol owed up for an average of 1.5 years and five patients were lost to fol ow-up. Joint locking, significant tenderness and movement disorder symptoms disappeared in 79 of 81 patients, and meniscal healing was shown on MRI review within 1 year after surgery;the Lysholm score was higher than 75 points, and the excel ent rate was 98%. Only the remained two patients felt swel ing and tenderness and the movement was slightly restricted when going down or standing up. The Fast-Fix combined with sodium hyaluronate in meniscal repair under arthroscope has good effect and good function of knee joint.
