Fang WANG, Jiaping LIU

《结构与土木工程前沿(英文)》 2010年 第4卷 第4期   页码 474-482 doi: 10.1007/s11709-010-0089-z

摘要: A number of ethnic minorities are being distributed in southwest China. Yunnan Province is an area inhabited by multi-ethnic groups. For a long time, the ethnic groups have been interacted by others in the cultural aspect, while retaining their own ethnic traditions. The performances of ethnic groups’ dwelling houses are similar as determined by natural and cultural elements of the same area. This paper mainly analyzes decisive factors behind similar appearances by the way of field research on two minorities, Nu ethnic group and Li-su ethnic group, in the Fugong county, Nujiang Li-su autonomous prefecture. Moreover, the paper tries to summarize the commonality and individuality of the minorities in order to provide useful theoretical reference for the minorities building of new socialist countryside in the future.

A highly selective fluorescent probe for real-time imaging of UDP-glucuronosyltransferase 1A8 in living

《化学科学与工程前沿(英文)》 2022年 第16卷 第1期   页码 103-111 doi: 10.1007/s11705-021-2064-8

摘要: Uridine diphosphate (UDP)-glucuronosyltransferases (UGTs) are enzymes involved in the biotransformation of important endogenous compounds such as steroids, bile acids, and hormones as well as exogenous substances including drugs, environmental toxicants, and carcinogens. Here, a novel fluorescent probe BDMP was developed based on boron-dipyrromethene (BODIPY) with high sensitivity for the detection of UGT1A8. The glucuronidation of BDMP not only exhibited a red-emission wavelength (λex/λem = 500/580 nm), but also displayed an excellent UGT1A8-dependent fluorescence signal with a good linear relationship with UGT1A8 concentration. Based on this perfect biocompatibility and cell permeability, BDMP was successfully used to image endogenous UGT1A8 in human cancer cell lines (LoVo and HCT15) in real time. In addition, BDMP could also be used to visualize UGT1A8 in tumor tissues. These results suggested that BDMP is a promising molecular tool for the investigation of UGT1A8-mediated physiological function in humans.

摘要:

据预测21世纪中期我国人口将净增2〜3亿,而耕地减少累计量将达1800万hm2,二者叠加到21世纪中叶我国将缺少4〜5亿人口的生存空间,人口、资源、环境形势非常严峻;而如何拓展生存空间的形势也是极其严重的,河流上游封山育林,中游退田还湖,但沿海滩涂却可提供大量后备土地资源。历史上我国退海、围海之地达10余万km2。近50年来,加大围海造地力度,新增了11000〜12000km2土地。本文提出2050年前再造10000〜15000km2生存空间,为2000〜3000万人提供就业机会,还着重提出未来50年围垦难点所在是低滩围垦。根据人海泥沙自然造陆与所需造陆之间的差值,必需以人工促淤和生物促淤工程来弥补自然成陆泥沙之不足。还需在提高环境监测、预测的精度,以及工程技术等方面的技术创新。

《医学前沿(英文)》 2008年 第2卷 第2期   页码 130-133 doi: 10.1007/s11684-008-0024-z

摘要: The aim of this paper is to summarize our experience of using right lobe liver grafts to reduce biliary complications in adult-to-adult (A-A) living donor liver transplantation (LDLT). From January 2002 to October 2007, 124 adult patients underwent living donor liver transplantation using right lobe grafts at the West China Hospital, Sichuan University Medical School, China. There was no death in all donors. Biliary reconstruction for 178 hepatic duct orifices from 124 donor grafts was performed which included 106 reconstructions of duct-to-duct anastomoses and 72 cholangiojejunostomy. Nine recipients had biliary complications including six bile leakages (four from the anastomotic site and two from the cut surface of the liver graft) and three biliary strictures. With the improved techniques for biliary reconstruction, we have achieved good results in 124 recipients of A-A LDLT. We ascribe our success to the introduction of microsurgical techniques and the use of fixed operators which help in decreasing the biliary complications of LDLT.

摘要: The aim of this paper is to report the authors experience in performing adult-to-adult living donor liver transplantation (LDLT) by using a modified technique in using grafts of the right lobe of the liver. From January 2002 to September 2006, 56 adult patients underwent LDLT using right lobe grafts at the West China Hospital, Sichuan University Medical School, China. All patients underwent a modified operation designed to improve the reconstruction of the right hepatic vein (RHV) and the tributariers of the middle hepatic vein (MHV) by interposing a vessel graft, and by anastomosing the hepatic arteries and bile ducts. There were no severe complications or deaths in all donors. Fifty-two (92.8%) recipients survived the operations. Among the 56 recipients, complications were seen in 15 recipients (26.8%), including hepatic vein stricture (one case), small-for-size syndrome (one case), hepatic artery thrombosis (two cases), intestinal bleeding (one case), bile leakage (two cases), left subphrenic abscess (one case), renal failure (two cases) and pulmonary infection (five cases). Within three months after transplantation, four recipients (7.14%) died due to smallfor-size syndrome (one case), renal failure (one case) and multiple organ failure (two cases). All patients underwent direct anastomoses of the RHV and the inferior vena cava (IVC), and in 23 cases, reconstruction of the right inferior hepatic vein was also done. In 24 patients, the reconstruction of the tributaries of the MHV was also done by interposing a vessel graft to provide sufficient venous outflow. Trifurcation of the portal vein was seen in nine cases. Thus, veno-plasty or separate anastomoses were performed. The graft and recipient body weight ratios (GRWR) were between 0.72% and 1.43%, and in three cases it was <0.8%. The graft weight to recipient standard liver volume ratios (GV/SLV) were between 31.86% and 71.68%, among which four cases had <40%. No small-for-size syndrome occurred. With modification of the surgical technique, especially in the reconstruction of the hepatic vein to provide sufficient venous outflow, living donor liver grafts in adults using the right lobe of the liver can become a relatively safe procedure and prevent the small-for-size syndrome .

摘要: Fulminant hepatitis is fatal in most cases and timely liver transplantation is the only effective treatment. This study evaluates the survival outcomes of patients who underwent living-donor liver transplantation (LDLT) using right lobe liver grafts for fulminant liver failure due to hepatitis B infection. Nine cases of adult right lobe LDLT were performed in our department from September 2002 to August 2005 and the clinical and following-up data were reviewed. According to the pre-transplant Child-Pugh-Turcotte classification, the nine patients were classified as grade C. The model for end-stage liver disease (MELD) score of these patients ranged from 16 to 42. The principal complications before transplantation included abnormal renal function, hepatic coma of different degrees and alimentary tract hemorrhage. The main complications after transplantation included pulmonary infection in two cases, acute renal failure in three cases and transplantation-related encephalopathy in one case. No primary failure of vascular or biliary complications occurred. The one-year survival rate was 55.6%. There were no serious complications or deaths in donors. In general, it is extremely difficult to treat fulminant hepatitis by conservative regimen, particularly, in cases with rapid progression. Emergency adult living-donor liver transplantation is an effective treatment for fulminant hepatitis patients and is relatively safe for donors.

摘要:

Partial liver transplantation, including reduced-size liver transplantation, split liver transplantation, and living donor liver transplantation, has been developed with several innovative techniques because of donor shortage. Reduced-size liver transplantation is based on Couinaud’s anatomical classification, benefiting children and small adult recipients but failing to relieve the overall donor shortage. Split liver transplantation provides chances to two or even more recipients when only one liver graft is available. The splitting technique must follow stricter anatomical and physiological criteria either ex situ or in situto ensure long-term quality. The first and most important issue involving living donor liver transplantation is donor safety. Before surgery, a series of donor evaluations—including anatomical, liver volume, and liver function evaluations—is indispensable, followed by ethnic agreement. At different recipient conditions, auxiliary liver transplantation and auxiliary partial orthotopic liver transplantation, which employ piggyback techniques, are good alternatives. Partial liver transplantation enriches the practice and knowledge of the transplant society.

Various brain-eating amoebae: the protozoa, the pathogenesis, and the disease

《医学前沿(英文)》 2021年 第15卷 第6期   页码 842-866 doi: 10.1007/s11684-021-0865-2

摘要: Among various genera of free-living amoebae prevalent in nature, some members are identified as causative agents of human encephalitis, in which Naegleria fowleri followed by Acanthamoeba spp. and Balamuthia mandrillaris have been successively discovered. As the three dominant genera responsible for infections, Acanthamoeba and Balamuthia work as opportunistic pathogens of granulomatous amoebic encephalitis in immunocompetent and immunocompromised individuals, whereas Naegleria induces primary amoebic meningoencephalitis mostly in healthy children and young adults as a more violent and deadly disease. Due to the lack of typical symptoms and laboratory findings, all these amoebic encephalitic diseases are difficult to diagnose. Considering that subsequent therapies are also affected, all these brain infections cause significant mortality worldwide, with more than 90% of the cases being fatal. Along with global warming and population explosion, expanding areas of human and amoebae activity in some regions lead to increased contact, resulting in more serious infections and drawing increased public attention. In this review, we summarize the present information of these pathogenic free-living amoebae, including their phylogeny, classification, biology, and ecology. The mechanisms of pathogenesis, immunology, pathophysiology, clinical manifestations, epidemiology, diagnosis, and therapies are also discussed.

《能源前沿(英文)》 2020年 第14卷 第4期   页码 836-849 doi: 10.1007/s11708-017-0444-z

摘要: This paper proposes a design of control and estimation strategy for induction motor based on the variable structure approach. It describes a coupling of sliding mode direct torque control (DTC) with sliding mode flux and speed observer. This algorithm uses direct torque control basics and the sliding mode approach. A robust electromagnetic torque and flux controllers are designed to overcome the conventional SVM-DTC drawbacks and to ensure fast response and full reference tracking with desired dynamic behavior and low ripple level. The sliding mode controller is used to generate reference voltages in stationary frame and give them to the controlled motor after modulation by a space vector modulation (SVM) inverter. The second aim of this paper is to design a sliding mode speed/flux observer which can improve the control performances by using a sensorless algorithm to get an accurate estimation, and consequently, increase the reliability of the system and decrease the cost of using sensors. The effectiveness of the whole composed control algorithm is investigated in different robustness tests with simulation using Matlab/Simulink and verified by real time experimental implementation based on dS pace 1104 board.
