3Helicobacter pylori colonization of the oral cavity:Amilestone discovery显示文摘Over the past several years, the severity of Helicobacter pylori(H. pylori) infections has not significantly diminished. After successful eradication, the annual H. pylori recurrence rate is approximately 13% due tooral H. pylori infection. Established clinical diagnostic techniques do not identify an oral etiologic basis of H. pylori prior to gastric infection. There has been disagreement as to whether oral infection of H. pylori exists or not, with no definite conclusion. In medical practice, negative results with the urea breath test suggest that the stomach infection of H. pylori is cured in these patients. In fact, patients can present negative urea breath test results and yet exhibit H. pylori infection due to oral infection. The present paper provides evidence that H. pylori oral infection is nonetheless present, and the oral cavity represents a secondary site for H. pylori colonization.John KC Yee 2016World Journal of Gastroenterology2016,22,2:13

7Doppler study of hepatic vein in cirrhotic patients:Correlation with liver dysfunction and hepatic hemodynamics显示文摘AIM: To elucidate the significance of Doppler measurements of hepatic vein in cirrhotic patients and to correlate with liver dysfunction and hepatic hemodynamics. METHODS: One hundred patients with liver cirrhosis and 60 non-cirrhotic controls were studied. Doppler waveforms were obtained from right hepatic vein and flow velocity measured during quiet respiration. Doppler measurements were also obtained from portal trunk, right portal vein and proper hepatic artery. RESULTS: Hepatic vein waveforms were classified into three classical patterns. Flat waveform was uncommon. Mean hepatic vein velocity was significantly higher in cirrhotic patients (12.7 ± 6.4 vs 5.1 ± 2.1 and 6.2 ± 3.2 cm/s; P < 0.0001). The poorer the grade of cirrhosis, the higher was the mean velocity. Maximum forward velocity was never greater than 40 cm/s in controls. Degree of ascites was found to be highly correlated with mean velocity. “Very high” group (≥ 20 cm/s) presented clinically with moderate to massive ascites. Correlations between right portal flow and mean velocity was significant (P < 0.0001, r = 0.687). CONCLUSION: Doppler waveforms of hepatic vein, which is independent of liver dysfunction, should be obtained during normal respiration. Mean hepatic vein velocity reflects the change in hepatic circulation associated with progression of liver cirrhosis. It can be used as a new parameter in the assessment of liver cirrhosis.KC Sudhamshu Shoiichi Matsutani Hitoshi Maruyama Taro Akiike Hiromitsu Saisho 2006World Journal of Gastroenterology2006,12,36:8
8运动对新发脂肪肝和已存在脂肪肝的影响显示文摘非酒精性脂肪性肝病(NAFLD)是指非饮酒所致的肝脏过多脂肪堆积,往往常见于超重、肥胖或罹患糖尿病、高胆固醇血症或高甘油三酯血症的个体。NAFLD是目前最常见的慢性肝脏疾病之一,影响了30%以上的一般人群,已成为一个严重的公共卫生负担。在全世界范围内,随着肥胖的流行,该综合征的患病率不断增加。当前,尚没有一种药物或手术获批用于治疗NAFLD。一些研究总结称,减重是唯一经证实的治疗NAFLD的有效方案。Sung KC Ryu S Lee JY 2016胃肠病学和肝病学杂志2016,25,12:7
9Child-Pugh-Turcott versus Meld score for predicting survival in a retrospective cohort of black African cirrhotic patients显示文摘AIM: To compare the performance of the Child-Pugh-Turcott (CPT) score to that of the model for end-stage liver disease (MELD) score in predicting survival of a retrospective cohort of 172 Black African patients with cirrhosis on a short and mid-term basis.METHODS: Univariate and multivariate (Cox model) analyses were used to identify factors related to mortality. Relationship between the two scores was appreciated by calculating the correlation coefficient. The Kaplan Meier method and the log rank test were used to elaborate and compare survival respectively. The Areas Under the Curves were used to compare the performance between scores at 3, 6 and 12 mo.RESULTS: The study population comprised 172 patients, of which 68.9% were male. The mean age of the patient was 47.5 ± 13 years. Hepatitis B virus infection was the cause of cirrhosis in 70% of the cases. The overall mortality was 31.4% over 11 years of follow up. Independent factors significantly associated with mortality were: CPT score (HR = 3.3, 95% CI [1.7-6.2]) (P < 0.001) (stage C vs stage A-B); Serum creatine (HR = 2.5, 95% CI [1.4-4.3]) (P = 0.001) (Serum creatine > 1.5 mg/dL versus serum creatine < 1.5 mg/dL); MELD score (HR = 2.9, 95% CI [1.63-5.21]) (P < 0.001) (MELD > 21 vs MELD < 21). The area under the curves (AUC) that predict survival was 0.72 and 0.75 at 3 mo (P = 0.68), 0.64 and 0.62 at 6 mo (P = 0.67), 0.69 and 0.64 at 12 mo (P = 0.38) respectively for the CPT score and the MELD score.CONCLUSION: The CPT score displays the sameprognostic significance as does the MELD score in black African patients with cirrhosis. Moreover, its handling appears less cumbersome in clinical practice as compared to the latter.KA Attia KC Ackoundou-N'guessan AT N’dri-yoman AK Mahassadi E Messou YF Bathaix YH Kissi 2008World Journal of Gastroenterology2008,14,2:5

13A UNIFIED ENERGY APPROACH TO A CLASS OF MICROMECHANICS MODELS FOR MICROCRACKED SOLIDS显示文摘Micromechanics models have been developed for the determination ofthe elastic moduli of microcracked solids based on different approaches andinterpretations,including the dilute or non-interacting solution,the Mori-Tanakamethod,the self-consistent method,and the generalized self-consistent method.It isshown in the present study that all these micromechanics models can be unified withinan energy-equivalence framework,and that they differ only in the way in which themicrocrack opening and sliding displacements are evaluated.Relevance to thedifferential methods and the verification of these models are discussed.HUANG, Y HWANG, KC 1995Acta Mechanica Solida Sinica1995,8,2:4
14印度Ganga-Meghna-Brahmaputra平原及周围地区与孟加拉国地下水砷污染及其对健康影响的19年研究显示文摘基于近19年对印度Ganga—Meghna—Brahmaputra(简称GMB)平原(面积569749km^2,人口超过5亿)地下水砷污染的调查,可以确定印度Ganga—Brahmaputra平原(包括北方邦、比哈尔邦、恰尔康得邦、西孟加拉邦、阿萨姆邦)和孟加拉国普遍受到砷的污染。近期的调查研究也表明,除米佐拉姆邦外,其他各邦的地下水也受到不同程度的砷污染。至今为止.已对印度各邦和孟加拧国的175000份和50808份压把井水样进行了含砷量检测。并组织了一支包括皮肤科、神经科和妇产科医生在内的有经验的专家组,对上述地区125000人进行了临床检查,其中9%患有砷导致的皮肤病损症状。至今共采集分析了60000份生物样品。包括发样、指甲、尿样及皮肤鳞屑,其中80%的样品含砷量超过允许值,很多人由此受到砷的亚临床损害。在上述砷暴露地区.19000名儿童经过检查,近1100人患有砷导致的皮肤病损。该调查结果表明.儿童比成人更容易受到砷的毒性损害。在这种状况下.应着力解决饮水安全问题来减轻砷的苊害.Ahamed S Hossain MA Mukharjee A Sengupta MK Das B Nayak B Pal A Mukherjee SC Pati S Dutta RN Saha KC Quamruzzaman Q Chakraborti D 付松波(译) 孙殿军(审校) 2007中国地方病学杂志2007,26,1:3
15Comparative study between intramedullary interlocking nailing and minimally invasive percutaneous plate osteosynthesis for distal tibia extra-articular fractures显示文摘Purpose:Treatment of distal tibia fractures poses significant challenge to orthopedic surgeon because of poor blood supply and paucity of soft tissue coverage.There is considerable controversy regarding the superior option of treatment for distal tibia fracture between the minimally invasive percutaneous plate osteosynthesis(MIPPO)technique and intramedullary interlocking(IMIL)nailing for extra-articular distal tibia fractures.The aim of our study is to compare the functional outcome between the two treatment methods.Methods:This was the prospective comparative study of 100 patients with distal third tibia fractures divided into two groups.The first group of patients were treated with MIPPO technique while the second group of patients were managed by IMIL nailing.Patients were followed up in outpatient department to assess the functional outcomes,malunion,delayed union,nonunion,superficial and deep infection between the two groups.Statistical analyses were performed using the SPSS software(version 16.0).Results:Average malunion(degrees)in the MIPPO group was 5(3—7)±1.41 vs.10.22(8—14)±2.04 in the IMIL group(p=0.001).Similarly postoperative knee pain in the IMIL group was 10%vs.2%in the MIPPO group(p=0.001).In terms of superficial infection and nonunion,the results were 8%vs.4%and 2%vs.6%for the MIPPO and IMIL group,respectively(p=0.001).Conclusion:Both procedures have shown the reliable method of fixation for distal extra-articular tibia fractures preserving the soft tissue,bony vascularity and fracture hematoma that provide a favourable biological environment for fracture healing.Considering the results of the study,we have slightly more preference for the MIPPO technique.Kapil Mani KC Bandhu Ram Pangeni Suman Babu Marahatta Arun Sigdel Amuda KC 2022Chinese Journal of Traumatology2022,25,2:3

19Liver transplantation for a giant mesenchymal hamartoma of the liver in an adult: Case report and review of the literature显示文摘Mesenchymal hamartomas of the liver(MHLs) in adults are rare and potentially premalignant lesions, which present as solid/cystic neoplasms. We report a rare case of orthotopic liver transplantation in a patient with a giant MHL. In 2013, a 34-year-old female sought medical advice after a 2-year history of progressive abdominal distention and respiratory distress. Physical examination revealed an extensive mass in the abdomen. Computed tomography(CT) of her abdomen revealed multiple liver cysts, with the diameter of largest cyst being 16 cm × 14 cm. The liver hilar structures were not clearly displayed. The adjacent organs were compressed and displaced. Initial laboratory tests, including biochemical investigations and coagulation profile, were unremarkable. Tumor markers, including levels of AFP, CEA and CA19-9, were within the normal ranges. The patient underwent orthotopic liver transplantation in November 2013, the liver being procured from a 40-year-old man after cardiac death following traumatic brain injury. Warm ischemic time was 7.5 min and cold ischemic time was 3 h. The recipient underwent classical orthotopic liver transplantation. The recipient operative procedure took 8.5 h, the anhepatic phase lasting for 1 h without the use of venovenous bypass. The immunosuppressive regimen includedintraoperative induction with basiliximab and high-dose methylprednisolone, and postoperative maintenance with tacrolimus, mycophenolate mofetil, and prednisone. The recipient's diseased liver weighed 21 kg(dry weight) and measured 41 cm × 32 cm × 31 cm. Histopathological examination confirmed the diagnosis of an MHL. The patient did not experience any acute rejection episode or other complication. All the laboratory tests returned to normal within one month after surgery. Three months after transplantation, the immunosuppressive therapy was reduced to tacrolimus monotherapy, and the T-tube was removed after cholangiography showed no abnormalities. Twelve months after transplantation, the patient remains well and is fulfilling all normal activities. Adult giant MHL is extremely rare. Symptoms, physical signs, laboratory results, and radiographic imaging are nonspecific and inconclusive. Surgical excision of the lesion is imperative to make a definite diagnosis and as a cure. Liver transplantation should be considered as an option in the treatment of a non-resectable MHL.Jiang Li Jin-Zhen Cai Qing-Jun Guo Jun-Jie Li Xiao-Ye Sun Zhan-Dong Hu David KC Cooper Zhong-Yang Shen 2015World Journal of Gastroenterology2015,21,20:3
