Clearing the clouds: Case‐report and review of the literature

In peritoneal dialysis (PD), a cloudy dialysate is an alarming finding. Bacterial peritonitis is the most common cause, however, atypical infections and non‐infectious causes must be considered. A 46‐year‐old man presented with asthenia, paraesthesia, foamy urine and hypertension. Laboratory testing revealed severe azotaemia, anaemia, hyperkalaemia and nephrotic‐range proteinuria. Haemodialysis was started through a central venous catheter. Later, due to patient preference, a Tenckhoff catheter was inserted. Conversion to PD occurred 3 weeks later, during hospitalization for a presumed central line infection. A month later, the patient was hospitalized for neutropenic fever. He was diagnosed an acute parvovirus infection and was discharged under isoniazid for latent tuberculosis. Four months later, the patient presented with fever and a cloudy effluent. Peritoneal fluid (PF) cytology was suggestive of infectious peritonitis, but the symptoms persisted despite antibiotic therapy. Bacterial and mycological cultures were negative. No neoplastic cells were detected. Mycobacterium tuberculosis eventually grew in PF cultures, despite previous negative molecular tests. Directed therapy was then initiated with excellent response. Thus, facing a cloudy effluent, one must consider multiple aetiologies. Diagnosis of peritoneal tuberculosis is hampered by the lack of highly sensitive and specific exams. Here, diagnosis was only possible due to positive mycobacterial cultures.     

槲皮素的结构修饰及生物活性研究进展

槲皮素是蔬菜、水果、中药中常见的黄酮类化合物,是天然的抗氧化剂,具有抗癌、抗糖尿病、抗菌、抗炎、抗病毒等生物活性。由于槲皮素生物利用度低,限制了其在临床上的应用。通过各种方法设计和合成新的槲皮素衍生物,以改善其缺点,进而发挥预防和治疗疾病的作用。通过对槲皮素衍生物的合成及其抗癌、抗糖尿病、抗炎、抗菌和抗病毒活性进行综述,并对其构效关系进行分析,为天然化合物的开发和利用奠定基础。

RNA silencing: a conserved antiviral immunity of plants and animals

RNA silencing is a novel RNA-guided gene regulatory mechanism operational in a wide range of eukaryotic organisms from fission yeast, plants, to mammals. This article reviews the recent progress on aspects of RNA silencing that are related to its biological function as a conserved antiviral immunity of plants and animals, and highlights features of this novel antiviral response in invertebrate animals as compared to the known innate and adaptive immunities. Finally, we discuss evidence that suggests a natural antiviral role for RNA silencing in vertebrates as well as experimental approaches that may facilitate the identification of first mammalian viral suppressors of RNA silencing.     

Preliminary study on immunotoxin for the prevention of Schistosomiasis japonica

To investigate the effects of immunotoxin (bio-missile) on the prevention of schistosomiasis. The monoclonal antibody NP11-4, located in out-layer membrane of adult worm, membrane of cercariae, membrane of schistosomula, shell of egg and membrane of miracidium in egg, was combined with artesunate (produced by Guilin Pharmaceutical Factory of China) by chemical method to fabricate immunotoxin.
