Aim: To examine lymph nodes obtained after lipolysis and liposuction of subcutaneous fat of the inguinal region of female vulvar cancer patients to explore the feasibility of clinical application. Methods: The field of operation was on the basis of the range of the conventional resection of inguinal lymph nodes. We injected lipolysis liquid fanwise, started liposuction after 15-20 minutes; then the subcutaneous fatty tissue was sucked out clearly by suction tube. We selected the first puncture holes located on 2-3 cm part below anterior superior spine, the others respectively being located 3cm and 6cm below the first for puncturing into the skin, imbedding a trocar to intorduce $CO_2$ gas and the specular body, and excise the lymph nodes by ultrasonic scalpel. The surgical field chamber was set with negative pressure drainage and was pressured with a soft saline bag after surgery. Results: A lacuna emerged from subcutaneous of the inguinal region after lipolysis and liposuction, with a wide fascia easily exposed at the bottom where lymph nodes could be readily excised. The number of lymph nodes of ten patients excised within the inguinal region on each side was 4-18. The excised average number of lymph nodes was 11 when we had mature technology. Conclusion: Most of adipose tissue was removed after lipolysis and liposuction of subcutaneous tissue of inguinal region, so that the included lymph nodes were exposed and easy to excise by endoscope. This surgery avoided the large incision of regular surgery of inguinal region, the results indicating that this approach is feasible and safe for used as an alternative technology.

汉语领属话题结构的认知考察

吴恒 ( Wu Heng ) 한국중국언어학회 2020 중국언어연구 Vol.0 No.89

Whether the possessive topic is established or not has achieved fruitful results from the perspective of generative grammar, in which semantic intersection and “most likely interpretation items” are operable, but due to the characteristics of generative grammar, there are still some phenomena that can not be well explained. From the perspective of function, this paper adopts the top-down method of focus test to explain some controversial topic structures. At the same time, this paper holds that the possessory structure is regarded as a prototype category, and the continuity of the possessory relationship is an important condition for the establishment of the possessive topic structure

Ping-Heng Wu,Chia-Tse Lee,Hsin-Chin Chen,Po-Tai Cheng 전력전자학회 2015 ICPE(ISPE)논문집 Vol.2015 No.6

As smart grid techniques are getting more positive perspective and expected to grow in the future, the STATic synchronous COMpensator (STATCOM) has become one of the most important roles to manage the power flow and regulate the grid voltage. The Modular Multilevel Cascaded Converter (MMCC) based on single star bridge cell (SSBC) is very suitable for STATCOM application at the medium-voltage level in the power system. The dc capacitors voltage balancing control is a critical issue to secure the stable operation of MMCCSSBC converter. Four different control methods based on power flow analysis have been considered. The performance of each controller is evaluated under steady state or even Low Voltage Ride Through (LVRT) operation. Each controller has its power flow management and its feature. Experimental test results are given to verify these control methods can well regulated the dc bus voltages under the unbalanced grid voltages.

Scaled Consensus of Disturbed Multi-agent Systems with Output Saturation

Heng Lei,Tao Han,Xi-Sheng Zhan,Jie Wu,Huaicheng Yan 제어·로봇·시스템학회 2022 International Journal of Control, Automation, and Vol.20 No.10

This paper studies the problem of scaled consensus with output saturation under exogenous disturbances, that is, under exogenous disturbances the state of the agent reaches an assigned proportion, rather than a common value. The main contribution of this work is to propose a new nonlinear protocol, which attenuates the exogenous disturbances by designing a disturbance observer, so that the states of all agents will be proportional to each other. In addition, with the help of integral Lyapunov function, a sufficient condition for the multi-agent system to achieve the scaled consensus with output saturation under exogenous disturbances is obtained under the directed strong connection graph. Finally, a simulation example is given to verify the validity of the results of this work.

Wu, Xun,Wang, Zhi-Feng,Xu, Yin,Ren, Rui,Heng, Bao-Li,Su, Ze-Xuan Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.13

Polymorphisms in the endothelial nitric oxide synthase (eNOS) gene may influence the risk of cancer, but the results are still debatable. Therefore, we performed a systematic review to provide a more complete picture and conducted a meta-analysis to derive a precise estimation. We searched PubMed, EMBASE, EBSCO, Google Scholar and China National Knowledge Infrastructure (CNKI) databases until April 2014 to identify eligible studies. Thirty-one studies with cancer patients and controls were included in the meta-analysis. Overall, the polled analysis revealed that the T-786C polymorphism was significantly associated with increased cancer risk under multiple genetic models (C vs T: OR=1.135, 95%CI=1.048-1.228; CC vs TT: OR=1.278, 95%CI=1.045-1.562; TC vsTT: OR=1.136, 95%CI=1.023-1.261; CC+TC vs TT: OR=1.159, 95%CI=1.047-1.281; CC vs TC+TT: OR=1.204, 95%CI= 1.003-1.447). G894T was associated with significant risk for females (TT vs GG: OR=1.414, 95%CI=1.056-1.892; TT vs GT+GG: OR=1.356, 95%CI=1.108-1.661) and for breast cancer (T vs G: OR=1.097, 95%CI=1.001-1.203; TT vs GG: OR=1.346, 95%CI=1.012-1.789; TT vs GT+GG: OR=1.269, 95%CI=1.028-1.566). Increased susceptibility was revealed for prostate cancer with 4a/b (ba vs bb: OR=1.338, 95%CI=1.013-1.768; aa+ba vs bb: OR=1.474, 95%CI=1.002-2.170). This meta-analysis indicated that the eNOS T-786C polymorphism is associated with elevated cancer risk; the G894T polymorphism contributes to susceptibility to breast cancer and cancer generally in females; and the 4a/b polymorphism may be associated with prostate cancer risk.

Si Heng Sharon Tan,Cheng Han Wu,Keng Lin Wong,James HoiPo Hui 대한초음파의학회 2020 ULTRASONOGRAPHY Vol.39 No.1

Purpose: The study aimed to investigate the utility of ultrasonographic (US) findings in predicting the subsequent radiographic parameters of developmental dysplasia of the hips. Methods: In this 12-year retrospective cohort study, all new-born infants with a positive clinical examination or risk factors were included. They were scheduled for hip ultrasonography in the first 3 months, and subsequent radiographs at 1 year of life. The US images were evaluated using the Graf classification, Harcke’s dynamic screening method, and Terjesen’s femoral head coverage method. The radiographic images were evaluated using the acetabular index and femoral head position. The overall US or radiographic findings were considered abnormal if they were classified as abnormal for any of their respective parameters. The overall US and radiographic parameters were correlated. Results: A total of 160 patients were included. The overall US and radiographic parameters showed no statistically significant difference (P=0.050). The sensitivity, specificity, and accuracy of the overall US parameters were 57.1%, 84.9%, and 81.3%, respectively. All three individual US parameters showed no statistically significant differences, with the overall radiographic findings and acetabular index (P>0.05). However, they showed a statistically significant difference, with the position of the femoral head (P<0.001), with the US parameters having an excellent negative predictive value of 100% for identifying an abnormal femoral head position. Conclusion: The current study suggests that US findings evaluated in the first 3 months of life showed no statistically significant difference with radiographic findings evaluated at 1 year of life. The US parameters showed an excellent negative predictive value for abnormal femoral head position on radiographs

Zhanjing Wu,Zhong Tao,Bei Liu,Heng Zuo 국제구조공학회 2020 Structural Engineering and Mechanics, An Int'l Jou Vol.73 No.6

The research study is focuses on a form of all-bolted joint with the external ring stiffening plate in the prefabricated steel structure. The components are bolted at site after being fabricated in the factory. Six specimens were tested under cyclic loading, and the effects of column axial compression ratio, concrete-filled column, beam flange sub plate, beam web angle cleats, and spliced column on the failure mode, hysteretic behavior and ductility of the joints were analyzed. The results shown that the proposed all-bolted joint with external ring stiffening plate performed high bearing capability, stable inflexibility degradation, high ductility and plump hysteretic curve. The primary failure modes were bucking at beam end, cracking at the variable section of the external ring stiffening plate, and finally welds fracturing between external ring stiffening plate and column wall. The bearing capability of the joints reduced with the axial compression ratio increased. The use of concrete-filled steel tube column can increase the bearing capability of joints. The existence of the beam flange sub plate, and beam web angle cleat improves the energy dissipation, ductility, bearing capacity and original rigidity of the joint, but also increase the stress concentration at the variable section of the external reinforcing ring plate. The proposed joints with spliced column also performed desirable integrity, large bearing capacity, initial stiffness and energy dissipation capacity for engineering application by reasonable design.

<P><B>Abstract</B></P> <P>Magnesium (Mg) and its alloys as biodegradable metallic materials have attracted fundamental research in the field of orthopedics and cardiovascular materials. However, magnesium implants exhibit poor corrosion resistance, especially in the physiological environment, which limits medical applications. To improve the corrosion resistance of the Mg, anodization was applied to an ultra-high concentration of fluoride electrolyte. Then, surface morphology, coating thickness and composition were determined, and the corrosion behavior of anodized Mg alloys was evaluated. The results of coating by anodization showed that a porosity structure with a pore size of 600–900nm and thickness of 1–14μm is generated on the Mg alloy substrate, and this coating component is magnesium fluoride. In electrochemical corrosion tests and immersion corrosion tests, the anodized Mg alloy was tested, and the anodized Mg alloy shows significantly improved corrosion resistance compared with untreated Mg alloy in simulated body fluid (SBF).</P> <P><B>Highlights</B></P> <P> <UL> <LI> A porous MgF<SUB>2</SUB> coating is created on Mg alloy by anodization in molten fluoride salt. </LI> <LI> The anodizing time is <30s. </LI> <LI> Corrosion resistance of the anodized Mg alloy is obviously improved. </LI> </UL> </P>
