Abstract
Abstract
Background
Secondary mitral regurgitation (SMR) impacts outcomes in heart failure with reduced ejection fraction (HFrEF) but whether it is a specific therapeutic target in heart failure patients with preserved ejection fraction (HFpEF) is less clear.
Purpose
The aims of this study were to investigate whether surgical or trans-catheter intervention reduces SMR and improves outcomes compared to optimal medical therapy in HFpEF patients.
Methods
We retrospectively identified 120 HFpEF patients with moderate-to-severe or greater SMR from January 1, 2007, until December 31, 2017. Moderate-to-severe SMR was defined as an effective regurgitant orifice area of >0.3cm2, and/or a regurgitation volume of >45ml per beat. Those with primary mitral regurgitation, endocarditis, HFrEF, hypertrophic cardiomyopathy, congenital heart disease, and history of valve intervention were excluded. All-cause mortality was analyzed and correlated to clinical and echocardiographic characteristics. Amongst the 120 patients, 36 received surgical or trans-catheter procedure in addition to medical therapy (procedure group) and 84 patients received optimal medical therapy only (conservative treatment group). The median follow-up period was 864 (15–3553) days.
Results
Patients in the procedure group were younger (75±8 vs 81±10, P=0.0002) and with fewer comorbidities (Charlson Comorbidity Index 7.0±2.4 vs 8.0±2.0, P=0.022) compared to the conservative treatment group. In addition, the procedure group had larger left ventricular end-diastolic diameters and higher SMR volume at baseline. During follow-up, SMR decreased by ≥2 grades in 75% of patients (27/36) in the procedure group compared to 20% of patients (12/60) in the conservative treatment group. After adjusting for age and comorbidities, the procedure group showed better overall survival compared to the conservative treatment group (HR 0.37; 95% CI 0.17–0.80; P=0.011). On multivariate analysis for the different groups (procedure group vs. conservative treatment group) (HR 0.40; 95% CI 0.17–0.91; P=0.019), increasing Charlson Comorbidity Index (HR 1.16; 95% CI 1.02–1.32; P=0.028) and average mitral E/e' ratio (HR 1.06; 95% CI 1.01–1.11; P=0.031) were independent predictors of increased all-cause mortality.
Kaplan-Meier Survival Curve
Conclusion
Among heart failure patients with preserved ejection fraction and moderate-to-severe or severe SMR, surgical or trans-catheter mitral-valve repair or replacement resulted in lower all-cause mortality compared to conservative treatment after 9 years of follow-up.

Abstract
Advanced, noninvasive imaging has revolutionized our understanding of language networks in the brain and is reshaping our approach to the presurgical evaluation of patients with epilepsy. Functional magnetic resonance imaging (fMRI) has had the greatest impact, unveiling the complexity of language organization and reorganization in patients with epilepsy both pre- and postoperatively, while volumetric MRI and diffusion tensor imaging have led to a greater appreciation of structural and microstructural correlates of language dysfunction in different epilepsy syndromes. In this article, we review recent literature describing how unimodal and multimodal imaging has advanced our knowledge of language networks and their plasticity in epilepsy, with a focus on the most frequently studied epilepsy syndrome in adults, temporal lobe epilepsy (TLE). We also describe how new analytic techniques (i.e., graph theory) are leading to a refined characterization of abnormal brain connectivity, and how subject-specific imaging profiles combined with clinical data may enhance the prediction of both seizure and language outcomes following surgical interventions.

Abstract
Objective: To investigate the early clinical outcomes of hip anterior short incision and open reduction and internal fixation for the treatment of children with Delbet Ⅱ femoral neck fracture. Methods: A retrospective analysis of 12 children with DelbetⅡ femoral neck fractures was performed with the anterior short incision approach at Department of Pediatric Orthopaedic, Children's Hospital, Nanjing Medical University from January 2014 to August 2016. There were 7 males and 5 females including 8 cases at left side and 4 cases at right side,aged (11.5±0.8) years (range: 8-14 years).Patients underwent surgery in (12.0±0.9) hours (range: 6-20 hours) after the injury. Displaced fractures were treated by open reduction if closed reduction failed.The surgical incision was performed with the anterior inferior iliac spine centered on, extending along the groin crease, and the length was 3 to 4 cm. The interval between the sartorius and the tensor fascia latae was applied, and the direct and indirect head of rectus femoris were resected to visualize the hip joint capsule. T-shaped incision was made in the capsule. After the reduction was obtained, two or three compression canulated screws were used to fix the fracture site. The healing time, complications and corresponding record outcome by X-ray and clinical examination were recorded. At the latest follow-up,the results were analyzed using the Ratliff criteria and clinical outcomes were assessed by pain, restrictive hip movement, normal activity or the avoidance of games, and the femoral neck in the radiograph. Results: Twelve patients had been followed-up for (30.0±4.1)months(range: 24-36 months). X-ray showed the fractures' healing time was (8.0±0.4) weeks(range: 7-9 weeks). Ten of the 12 fractures healed after one operation and were associated with no evidence of osteonecrosis of the femoral head. One case occurred premature physeal closure. There were no cases with fracture relocation, coaxvara, delayed union and nonunion or any significant postoperative complications. There was no infection, flexible internal fixation or ruptures. According to Ratliff grade, 9 cases of 12 patients were fine and 3 cases was acceptable. Conclusions: Satisfactory short-term effects can be achieved by a mini-incision on the anterior hip for Delbet Ⅱ pediatric femur neck fractures. The anterior incision has the advantage of less trauma, smaller incision scar, better fracture reduction and fixation, and less wound complications.

Abstract
AIM Our aim was to compare short- and long-term oncological outcomes between laparoscopic and open colectomy in T4 colon cancer. METHODS We retrospectively analysed oncological outcomes of 94 patients who underwent surgery between December 2010 and December 2016 for pT4 colon cancer, with propensity score matching. All patients were treated with curative intent, by either laparoscopic or open en bloc resection. RESULTS The conversion rate in the laparoscopic group was 17.0%. Blood loss, time to flatus and postoperative hospitalization were significantly less in the laparoscopic group. Postoperative morbidity and mortality within 30 days did not significantly differ between the two groups. R0 resection rates and lymph node harvests were similar between the two groups. At 5 years, laparoscopic outcomes were not inferior to open outcomes (overall survival 56.8% vs 50.2%, P = 0.250; disease-free survival 59.7% vs 41.7%, P = 0.06). CONCLUSION The laparoscopic approach is safe and feasible for pathologically confirmed T4 colon cancer. It results in a faster postoperative recovery.

Abstract
This research presents a new turbulence generation method based on stochastic wavelets and tests various properties of the generated turbulence field in both the homogeneous and inhomogeneous cases. Numerical results indicate that turbulence fields can be generated with much smaller bases in comparison to synthetic Fourier methods while maintaining comparable accuracy. Adaptive generation of inhomogeneous turbulence is achieved by a scale reduction algorithm, which greatly reduces the computation cost and practically introduces no error. The generating formula issued in this research could be adjusted to generate fully inhomogeneous and anisotropic turbulence with given RANS data under divergence-free constraint, which was not achieved previously in similar research. Numerical examples shows that the generated homogeneous and inhomogeneous turbulence are in good agreement with the input data and theoretical results.

Abstract
A highly crystalline nanosized spinel LiMn2O4/3DG composite cathode material for high rate lithium ion batteries was successfully prepared by mixing spinel LiMn2O4 particles with reduced graphene oxide (3DG). Spinel LiMn2O4 and reduced three-dimensional graphene oxide were synthesized using a hydrothermal method and freeze-drying technology, respectively. The structure, morphology and electrochemical performance of the synthesized materials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and galvanostatic charge–discharge techniques. The results showed that the LiMn2O4/3DG composites exhibited excellent rate capability and stable cycling performance. The discharge capacity was 131 mA h g−1 and the capacity remains at 89.3% after 100 cycles at a 0.5 C rate, while the discharge capacity was 90 mA h g−1 at 10 C. Compared with spinel LiMn2O4 materials, the LiMn2O4/3DG composites showed obvious improvement in electrochemical performance. 3DG/LiMn2O4 composites exhibit a high specific capacity and excellent rate performance.![]()

Abstract
BACKGROUND Although tremendous efforts have been made to reduce rubella incidence, there are still 300 new cases of congenital rubella syndrome daily; thus, rubella infections remain one of the leading causes of preventable congenital birth defects. An effective surveillance system, which could be achieved and maintained by using an external quality assessment program, is critical for prevention and control of this disease. METHODS Armored RNAs, which are noninfectious and RNase-resistant, were used for encapsulation of the E1 gene of rubella virus and for preparation of a 10-specimen panel for external quality assessment. Thirty-two laboratories across mainland China that used nucleic acid tests for rubella virus RNA detection were included in the external quality assessment program organized by the National Center for Clinical Laboratories of China. RESULTS Different kinds of commercial kits were used by the laboratories for nucleic acid extraction and TaqMan real-time reverse-transcription PCR for rubella virus RNA detection; 99.2% sensitivity and 100% specificity were achieved in this external quality assessment program. CONCLUSIONS Most of the participating laboratories obtained accurate results for rubella nucleic acid tests, thereby achieving the quality required for regional rubella and congenital rubella syndrome elimination.
