BACKGROUND:Pyogenic liver abscess(PLA)is commonly seen in patients in the Far ***,hepatobiliary neoplasms are also *** as the initial manifestation of hepatobiliary neoplasms is extremely rare. METHOD:Three patients with PLA were identified from the ward registion files and were retrospectively reviewed. RESULTS:These patients(two men aged 74 and 80 years, and one woman aged 35 years)were treated(in the right lobe in two patients and in the left lobe in one)and subsequently followed up for 11-22 *** patients were diagnosed with hepatocellular carcinoma and one with metastatic *** patients were subjected to biopsies showing features of inflammatory pseudotumor before a diagnosis of hepatocellular *** patient underwent hepatic resection with good *** the other two patients who declined any further interventions,one died a few weeks after diagnosis and the other is still alive on conservative treatment. CONCLUSIONS:This series of cases highlights the importance of considering underlying hepatobiliary malignancies in patients with PLA and a close follow-up necessary for non-resolving hepatic lesions.

BACKGROUND:Gallstone disease is common,and complications that are frequently encountered include acute cholecystitis and acute pancreatitis,but rarely gallbladder perforation. METHOD:Data were retrospectively collected from clinical case notes and a literature review is presented. RESULTS:A 72-year-old lady presented with spontaneous gallbladder perforation,pericholecystic abscess and cholecystoduodenal fistula as the first manifestations of gallstone *** was previously well and had no abdominal *** condition was successfully managed with initial antibiotic therapy followed by interval cholecystectomy and fistula repair. CONCLUSIONS:Our case highlighted some uncommon but severe complications which occurred simultaneously as the first manifestations of previously asymptomatic gallstone *** complications need to be considered in patients suspected of intra-abdominal sepsis,even when there are no characteristic symptoms.

AIM： To determine whether alteration of the mito- chondria DNA （mtDNA） copy number and its oxidative damage index （mtDNA△CT） can be detected by analysis of peripheral blood cells in hepatitis C virus （HCV）- infected patients. METHODS： This study enrolled two groups of pa- tients aged 40-60 years： a control group and an HCV- infected group in Department of Gastroenterology and Hepatology in Changhua Christian Hospital. Patients with co-infection with hepatitis B virus or human im- munodeficiency virus, autoimmune disease, malignant neoplasia, pregnancy, thyroid disease, or alcohol con- sumption 〉 40 g/d were excluded. HCV-infected pa- tients who met the following criteria were included：（1） positive HCV antibodies for 〉 6 mo; （2） alanine aminotransferase （ALT） levels more than twice the upper lim- it of normal on at least two occasions during the past 6 mo; and （3） histological fibrosis stage higher than F1. The mtDNA copy number and oxidative damage index of HCV mtDNA （mtDNA△CT） were measured in periph- eral blood leukocytes. The association between mtDNA copy number and mtDNA△CT was further analyzed using clinical data. RESULTS： Forty-seven normal controls （male/female： 26/21, mean age 50.51 ± 6.15 years） and 132 HCV- infected patients （male/female： 76/61, mean age 51.65 ± 5.50 years） were included in the study. The geno- types of HCV-infected patients include type 1a （n = 3）, type 1b （n = 83）, type 2a （n = 32）, and type 2b （n = 14）. Liver fibrosis stages were distributed as follows： F1/F2/F3/F4 = 1/61/45/25 and activity scores were A0/ A1/A2/A3 = 7/45/55/25. There were no age or gender differences between the two groups. HCV-infected pa- tients had higher hepatitis activity （aspartate transami- nase levels 108.77 ± 60.73 vs 23.19 ± 5.47, P 〈 0.01; ALT levels 168.69 ± 93.12 vs 23.15 ± 9.45, P 〈 0.01） and lower platelet count （170.40±58.00 vs 251.24 ± 63.42, P 〈 0.01） than controls. The mtDNA copy num- ber was lower in HCV-infected patients than in controls （173.49

针对Informed-RRT^(*)算法初始路径形成缓慢、失败率高及路径质量差的问题,提出基于人工势场法的选点策略。首先,筛选出优质采样点,同时,引入双向直连的贪心策略和动态步长策略,快速获得初始路径并尽快进入遍历寻优阶段;其次,通过新的采样策略及评价函数,保证规划路径更优;最后,对路径优化处理,所得路径更适合移动机器人的行驶。仿真实验结果表明,改进算法相比于Informed-RRT^(*)算法性能更优,其中,改进算法在不同环境中的成功率均为100%,同时也证明了在限定采样次数下改进算法的收敛速度、路径质量均优于原算法。

AIM: Gastrografin is a hyperosmolar water-soluble contrast medium. Besides its predictive value for the need for operative treatment, a potential therapeutic role of this agent in adhesive small bowel obstruction has been suggested. This study aimed at evaluating the effectiveness of gastrografin in adhesive small bowel obstruction when conservative treatment failed. METHODS: Patients with adhesive small bowel obstruction were given trial conservative treatment unless there was fear of bowel strangulation. Those responded in the initial 48 h had conservative treatment continued. Patients who showed no improvement in the initial 48 h were given 100 mL of gastrografin through nasogastric tube followed by serial abdominal radiographs. Patients with the contrast appeared in large bowel within 24 h were regarded as having partial obstruction and conservative treatment was continued. Patients in which the contrast failed to reach large bowel within 24 h were considered to have complete obstruction and laparotomy was performed. RESULTS: Two hundred and twelve patients with 245 episodes of adhesive obstruction were included. Fifteen patients were operated on soon after admission due to fear of strangulation. One hundred and eighty-six episodes of obstruction showed improvement in the initial 48 h and conservative treatment was continued. Two patients had subsequent operations because of persistent obstruction. Forty-four episodes of obstruction showed no improvement within 48 h and gastrografin was administered. Seven patients underwent complete obstruction surgery. Partial obstruction was demonstrated in 37 other cases, obstruction resolved subsequently in all of them except one patient who required laparotomy because of persistent obstruction. The overall operative rate in this study was 10%. There was no complication that could be attributed to the use of gastrografin. CONCLUSION: The use of gastrografin in adhesive small bowel obstruction after unsuccessful conservative

High-performance GaInP/AlGaInP multi-quantum well light-emitting diodes(LEDs) grown on a low threading dislocation density(TDD) germanium-on-insulator(GOI) substrate have been demonstrated. The low TDD of the GOI substrate is realized through Ge epitaxial growth, wafer bonding, and layer transfer processes on 200 mm wafers. With O_2 annealing, the TDD of the GOI substrate can be reduced to ~1.2 × 10~6 cm^(-2). LEDs fabricated on this GOI substrate exhibit record-high optical output power of 1.3 mW at a 670 nm peak wavelength under 280 mA current injection. This output power level is at least 2 times higher compared to other reports of similar devices on a silicon(Si) substrate without degrading the electrical performance. These results demonstrate great promise for the monolithic integration of visible-band optical sources with Si-based electronic circuitry and realization of high-density RGB(red, green, and blue) micro-LED arrays with control circuitry.

t is obviously headline news when a transnational corporation brings a lawsuit against a journalist - espe-cially in the circumstances that it is the public relation （PR） director of one of the world＇s most famous auto companies who is suing one of China＇s leading auto jour nalists, someone whom he would normally be courting. Although the action appears to have been intended as little more than a warning, since the lawsuit was dropped almost as soon as it was launched, ittouched off heated public debate and has done serious damage to the public image of Volkswagen.

明治初年日本人在对外关系的认识上呈现出三重性结构,致使福泽谕吉等人在论及东洋与西洋的关系时,主张以实现日本的东洋盟主地位来遏制西洋。但出于对中国清朝通过洋务运动以增强国力的担忧和警戒,便很快转向“脱亚入欧论”。这几乎可以说是近代以来中日关系中的一项定律。
