Coexistence of benign phyllodes tumor and invasive ductal carcinoma in distinct breasts: case report

This report describes a rare case of coexistence of benign phyllodes tumor, which measured 9 cm in the right breast, and invasive ductal carcinoma of 6 cm in the left breast, synchronous and independent, in a 66-year-old patient. The patient underwent a bilateral mastectomy due to the size of both lesions. Such situations are rare and usually refer to the occurrence of ductal or lobular carcinoma in situ when associated with malignant phyllodes tumors, and more often in ipsilateral breast or intra-lesional.     

The effects of pulp and paper mill effluent on physiological and hematological endpoints in fingerling largemouth bass (Micropterus salmoides)

The purpose of this study was to evaluate the effects of bleached kraft mill effluent on selected physiological and hematological endpoints in fingerling largemouth bass (Micropterus salmoides). Fish were exposed for 35 days to surface water collected at sites up- and downstream from a pulp and paper mill treatment-effluent discharge. The condition factor, spleen somatic index, and pronephros cellularity were statistically significantly decreased in fish exposed to the downstream site, compared to the upstream site. There was also a shift from lymphocytes to neutrophils in peripheral blood of fish exposed to the downstream site. Hematocrit values and the liver somatic index were statistically significantly increased in fish in the downstream exposure. These results indicate that in-stream exposure to elemental-chlorine-free pulp and paper mill effluents produce a generalized stress response, leading to potential immunosuppression in fish.     

肝脏增强CT扫描与MRI在肝癌诊断中的研究价值

目的探讨增强CT扫描与MRI在肝癌诊断中的价值。方法回顾性分析2014年5月至2016年3月在本院进行影像检查并经手术病理确认的60例肝癌患者的临床资料和影像资料,同时对患者癌变部进行归类分析,并通过两种影像检查方法的确诊率来评判两种检查方式的价值。结果60例中,巨块型占总数,结节型占总数54.5%,小肝癌例数占总数30.3%。增强CT对肝癌患者的总检出率为91.2%,MRI对肝癌患者的总检出率为92.3%。两者无明显统计学差异。结论在肝癌的确诊方面,MRI和增强CT扫描均具有较高的精度,可以作进一步推广应用。     

Differential actions of NPY on seizure modulation via Y1 and Y2 receptors: evidence from receptor knockout mice

PURPOSE: Neuropeptide Y (NPY) has been shown to modulate seizure activities. To provide further understanding of the involvement of two of the most abundantly expressed NPY receptors, Y1 and Y2, we assessed the effect of Y1 and Y2 gene deletion on systemic kainic acid-induced seizures. We also examined the effect of rAAV-mediated hippocampal NPY overexpression on seizure susceptibility in these receptor knockout mice. METHODS: Recombinant adeno-associated viral vector overexpressing NPY (rAAV-NPY) or an empty vector control (rAAV-Empty) was injected into the hippocampus of adult C57BL/6-129/SvJ wild-type male mice and mice deficient of Y1 or Y2 receptors on the same background. Four weeks after vector injection, mice were subjected to systemic kainic acid-induced seizures, and the seizure behaviors were scored. RESULTS: The rAAV-mediated hippocampal overexpression of NPY led to a twofold reduction in seizures induced by systemic kainic acid in wild-type mice and Y1 receptor knockout mice but not in mice deficient of Y2 receptors. A differential action by the receptors was observed in the seizure-induced mortality rate, with increased fatality in Y2-/- mice. In addition, although NPY overexpression did not significantly affect the mortality rate in Y2-/- and wild-type mice, it abolished KA-induced mortality in Y1-/-mice. CONCLUSIONS: This study shows for the first time an altered susceptibility to chemically induced seizures in Y1 and Y2 knockout mice and demonstrates a differential seizure modulation mediated by these receptors via a genetic approach.

肛门镜压迫下内痔注射法治疗Ⅱ、Ⅲ期内痔的临床疗效

为探讨新型肛门镜压迫下内痔注射法治疗Ⅱ、Ⅲ期内痔的临床疗效,本研究采用多中心随机对照方法,选取200例Ⅱ、Ⅲ期内痔患者分为试验组及对照组,各i00例,试验组采用新型肛门镜压迫下内痔注射法治疗,对照组采用传统消痔灵注射法治疗,观察两组疗效及不良反应。结果显示,试验组治愈84例,好转12例,无效4例,治愈率为84．0％;对照组治愈30例,好转58例,无效12例,治愈率为30．0％。试验组治愈率明显高于对照组,P〈0．01。两组术后第3天出血治愈率差异无统计学意义,P〉0．05;但试验组术后痔核脱出、肛门坠胀治愈率明显高于对照组,P〈0．01。结果表明,肛门镜压迫下内痔注射法治疗Ⅱ、Ⅲ期内痔疗效确切,与传统消痔灵注射法比较,在治疗内痔脱出方面具有更高的临床实用价值。？     

Pylorus-preserving total pancreatectomy. Early and late results.

BACKGROUND/AIMS: Preservation of the pylorus is an accepted alternative procedure to the classical Whipple operation for pancreatic head resection but data describing its value for total pancreatectomy are sparse. METHODS: A prospective analysis of 22 total pancreatectomies performed in a consecutive series of 436 pancreatic resections from 1.11.93 to 1.5.99. RESULTS: 11 patients underwent total pancreatectomy with preservation of the pylorus. Histopathological examination revealed pancreatic adenocarcinoma in 16 cases and duodenal adenocarcinoma in 1 patient, 5 patients had other types of pancreatic neoplasm. In-hospital mortality was 4.5% (n = 1), cumulative morbidity was 59% and reoperations were performed in 9.1% of cases (n = 2). Median follow-up was 37 months (range 5-66). 62% of patients (n = 13) developed tumor recurrence and 13 patients died during the follow-up period with 10 deaths being cancer related. There was no difference concerning postoperative and follow-up morbidity of survival between patients undergoing pylorus-preserving total pancreatectomy or pancreatectomy with gastrectomy. However, postoperative body weight was increased 3, 6, 9 and 12 months following preservation of the pylorus. CONCLUSION: Total pancreatectomy with preservation of the pylorus is a feasible type of resection for all types of pancreatic or ampullary tumors, which shows a similar morbidity and long-term survival but improved nutritional recovery compared with standard total pancreatectomy.
