Objective To compare the clinical features between cryptogenic stoke(CS)with and without right-to-left shunt(RLS)so as to determine whether shunt severity determined by control-enhanced transcranial Doppler(c-TCD)is correlated with the risk of paradoxical embolism(RoPE)score.Methods We made a retrospective analysis of clinical characteristics of 138 CS patients with and without RLS admitted to our department between January 2014 and November 2016.For patients documented by c-TCD,we evaluated whether there was a correlation between RLS severity and RoPE score. RLS was diagnosed by c-TCD and contrast-enhanced transthoracic echocardiography(c-TTE).We compared every modality for detecting RLS with and without Valsalva maneuver.For patients found with RLS in c-TCD and c-TTE,we judged whether there was an agreement in grading RLS between two modalities.Results For patients with CS,shunt severity by c-TCD was positively correlated with RoPE score(r= 0.26,P= 0.05).The clinical features were different between CS patients with RLS and without RLS.Compared with the positive results of c-TCD and c-TTE at rest,the positive rate was higher in Valsalva maneuver,respectively(P＜0.01).There was a moderate agreement between shunt grades identified by the two techniques(Kappa=0.428).Conclusion There is a positive correlation between RoPE score and RLS severity determined by c-TCD in CS patients.Valsalva maneuver can significantly increase the positive rate of RLS detected by c-TCD and c-TTE.

BACKGROUND: With the improvement of medical imaging technology, the visualization of human anatomy has been further developed; the role of three-dimensional (3D) reconstruction in medical treatment is also becoming increasingly prominent. Mimics is the most widely used medical image reconstruction software. Arigin 3D Pro is a recently developed 3D reconstructed medical software system based on 3D printing. OBJECTIVE: To study the accuracy of 3D reconstruction models obtained by using Arigin 3D Pro and Mimics with medical images. METHODS: The image data of liver, spine, knee joint and heart were selected, and the deviations of two software reconstruction models were analyzed based on the 3D model reconstructed by Mimics. Totally 10 cases of skull and 1 case of femoral comminuted fracture image data were selected and reconstructed. Each reconstruction model was measured with 10 groups of feature sizes to evaluate the differences between the two software programs. RESULTS AND CONCLUSION: Arigin 3D Pro and Mimics were used to reconstruct the liver, spine, knee and heart data. The mean ± standard deviation of model deviations were (0.93 ± 1.05), (0.36 ± 0.74), (0.45 ± 0.74), (0.18 ± 0.41) mm. It took 3 minutes and 35 minutes for Arigin 3D Pro and Mimics to reconstruct the liver model respectively, and both software reconstructed other models for less than 1 minute. There was no statistically significant difference between the feature sizes of the two software for the 3D reconstruction models of skull and femoral comminuted fracture data (P > 0.05). The 3D reconstruction model of Arigin 3D Pro is comparable to that of Mimics. For the liver model, the reconstructed time of Arigin 3D Pro is significantly shorter than that of Mimics.

OBJECTIVETo investigate electrocardiographic (ECG) and angiographic characteristics of patients with acute solitary posterior myocardial infarction. Patients complicated by inferior wall or right ventricular infarction were excluded.

METHODECG and angiographic changes in 11 patients with acute solitary posterior myocardial infarction admitted to our emergency room from 2001 to 2006 were analyzed.

RESULTSBesides typical ST segment elevation in V(7)-V(9) leads, other ECG manifestations in these patients included V(1)-V(2) R/S > or = 1 (9/11, 81.8%), 1 - 2 mm ST depression in V(1)-V(4) (5/11, 45.5%), 0.5 - 1.5 mm ST elevation in I, aVL leads (4/11, 36.4%) and 0.5 - 1.5 mm ST elevation in V(5)-V(6) leads (5/11, 45.5%). Coronary angiography showed that left circumflex artery (LCX) was the infarction related artery in all cases. The infarction area located before OM1 origination in 1 patient with a 95% pipe-like stenosis (1/11), after OM1 origination in 6 patients (6/11, 4 with total occlusion, 1 with sub-total occlusion and 1 with 90% long length stenosis), in OM1 in 4 patients (4/11, 2 with total occlusion, 1 with sub-total occlusion and 1 with 95% local stenosis). There were 3 patients (27.3%) with single vessel lesion, 4 patients (36.4%) combined with left anterior descending artery (LAD) lesion, 2 patients (18.2%) combined with right coronary artery (RCA) lesion and 2 patients (18.2%) combined with LAD and RCA lesions.

CONCLUSIONSAcute posterior myocardial infarction should be suspected with V(1)-V(2) R/S > or = 1 and V(1)-V(4) ST depression in standard 12 leads ECG. Besides symptoms and cardiac enzyme measurements, recording posterior leads electrocardiogram and performing coronary angiography will help to make the correct diagnosis.

BACKGROUNDKnowledge about factors influencing the prognosis of resective epilepsy surgery can be used to identify which patients are most suitable for surgical treatment. The aim of this study was to identify preoperative prognostic factors associated with the chance of achieving long-term seizure freedom.

METHODSWe retrospectively reviewed seizure outcomes and clinical, electroencephalography (EEG), magnetic resonance imaging (MRI), histopathology, and surgical variables from 99 epilepsy surgery patients with at least one year of postoperative follow-up. Seizure outcomes were categorized based on the modified classification by the International League Against Epilepsy.

RESULTSWe found that the seizure-free rate was 27.9% after one year, and that it stabilized at about 20.0% between two and six years after surgery. Univariate analysis showed that medial temporal lobe epilepsy with hippocampal sclerosis, MRI with visible focal lesions concordant with EEG, and regional ictal EEG and electrocorticography patterns were associated with a favorable surgical outcome. On the other hand, seizure recurrence within six months, incomplete focus resection, and surgical complications were associated with a poor outcome. Multivariate analysis showed that medial temporal lobe epilepsy with hippocampal sclerosis and MRI with visible focal lesions were independent presurgical predictors of a favorable outcome (P < 0.01). Seizure recurrence within six months was the only significant independent predictor associated with a poor outcome (P < 0.01).

CONCLUSIONHippocampal sclerosis and abnormal MRI findings are strongly associated with a favorable surgical outcome, whereas seizure recurrence within six months is associated with a poor outcome.

Objective To investigate the effects of life-style intervention on obstructive sleep apnea-hypopnea syndrome (OSAHS).Methods A number of 168 cases with OSAHS were randomized into intervention group ( n =81 ) and control group ( n =87 ).In the interventional group,the patients received uvulopalatopharyngoplasty and life-style intervention,including cognition guide,proper diet,weight control,stopping smoking or drinking,and exercise.The control group received uvulopalatopharyngoplasty only and their living was just as usual.polysomography,body mass index ( BMI ),and symptom assessment were monitored Imonth,6months,12months and 24months after operation.The patients were followed up for more than 2 years.Results There was no statistical differences in life style between the two groups prior to intervention(P ＞0.05).The proportion of a healthy diet manner,cessation in alcohol and smoking,weight loss or good control in weight,moderate exercise between the two groups (93.8％,86.4％,69.1％,81.5％,87.7％ in intervention group,and 11.5％,36.8％,21.8％,17.2％,9.2％ in control group) showed statistical differences after intervention(x2=113.80,43.33,37.97,69.33,103.70,respectively;P ＜0.01 ).Compared to the control group,patients in intervention group had a significant improved in lowest oxygen saturation( LSa02 ),apnea hypopnea index(AHI),snoring index and BMI at 6,12,24 months after intervention(t =2.51,4.13,7.88;2.10,2.66,3.68;3.42,4.17,9.34 ;5.92,12.78,9.37 ; respectively; P ＜ 0.01 ).The observational index in intervention group before and after intervention showed statistical differences (P ＜ 0.01 ) while no difference in control group(P ＞ 0.05).Conclusions It can improve the clinical symptoms and improve the long-term efficacy of surgical treatment to reduce cardiovascular and cerebrovascular complications for uvulopalatopharyngoplasty and life-style intervention on the patients with obstructive sleep apnea-hypopnea syndrome,which not only improves the life quality of the patients,but also reduce their economic burden.It is worthy of clinical application.

OBJECTIVETo evaluate the influence of Shenfu Injection (SHF) on the quality of life of patients with advanced non-small cell lung cancer (NSCLC) receiving chemotherapy.

METHODSA total of 133 patients with NSCLC receiving at least two cycles of chemotherapy with taxol plus cisplatin (TP)/vinorelbine plus cisplatin (NP) or gemcitabine plus cisplatin (GP) were randomized into SHF pre-treatment group (with SHF given only in the first cycle) and SHF post-treatment group (with SHF given only in the second cycle). The Quality of Life Questionnaire-Core 30 (QLQ-C30) and the Functional Living Index-Cancer (FLIC) were used to evaluate the quality of life of the patients after the treatments.

RESULTSBoth of the groups showed improved quality of life after the treatments (P<0.01), but the improvements were more obvious in SHF pre-treatment group (P<0.05). SHF showed favorable effects in relieving such adverse effects as fatigue, nausea, vomiting and diarrhea associated with the chemotherapy.

CONCLUSIONSHF can improve the quality of life in NSCLC patients receiving chemotherapies.

Mitochondria are subcellular organelles that provide energy for the cell. They form a dynamic tubular network and play an important role in maintaining the cell function and integrity. Heart is a powerful organ that supplies the motivation for circulation, thereby requiring large amounts of energy. Thus, the healthiness of cardiomyocytes and mitochondria is necessary for the normal cardiac function. Mitochondria not only lie in the center of the cell apoptotic pathway, but also are the major source of reactive oxygen species (ROS) generation. Mitochondrial morphological change includes fission and fusion that are regulated by a large number of proteins. In this review we discuss the regulators of mitochondrial fission/fusion and their association with cell apoptosis, autophagy and ROS production in the heart.

OBJECTIVETo explore the status of child neglect among rural areas children aged 0 - 6 years in China.

METHODSA total of 7411 rural children aged 0 - 6 years old who were composed of two age groups (3315 children aged 0 - 2 years old and 4096 children aged 3 - 6 years old) were multistage stratified randomly sampled from 84 villages which were representative of 10 provinces of China, in accordance with sex and age in November 2010. To identify the child neglect based on the Neglect Norms for Children Aged 0 to 2 and 3 to 6 Years Old in Rural Areas of China, SPSS 13.0 was employed for analyzing neglect frequency and degree for every group of different age, sex and neglect type (including physical, emotional, educational, medical, safety and social neglects). χ(2) test and analysis of variance were also used.

RESULTSThe degree of child neglect for the children aged 0 - 2 years old was 45.01 ± 7.56, the neglect frequency was 54.9% (1819/3315); the degree of child neglect for the children aged 3 - 6 years old was 44.42 ± 7.57, the neglect frequency was 53.8% (2203/4096). The neglect frequency of children aged 0, 1, 2 years old were 58.5% (654/1117), 52.2% (597/1144), 53.9% (568/1054) (P < 0.05). For children aged 3 - 6 years old, the degrees of emotional and safety neglect for males (44.60 ± 7.86, 36.82 ± 9.03) were higher than females (44.03 ± 7.72, 36.25 ± 9.05) (P < 0.05); and the frequencies of emotional and social neglect for males (16.8% (349/2072), 28.3% (586/2072)) were also higher than females (14.1% (286/2024), 24.8% (503/2024)) (P < 0.05). All children of two age groups suffered neglect mainly on one of the six neglect types (incidences were 20.6% (683/3315) and 22.7% (931/4096)). For 0-2 age groups, the higher neglect frequencies happened in the single-parent family and the remarried family (62.5% (15/24) and 63.2% (12/19)), but for children aged 3 - 6 years old groups, it happened in the single-parent family (60.0%, 27/45).

CONCLUSIONDegree and frequency of child neglect among children aged 0 to 6 years old in the rural areas of China are high, and we should find out risk factors and provide efficient prevention measures.
