Abstract: Objective　To investigate the clinical characteristics and diagnosis key points of brain abscess caused by Nocardia asiatica, and provide a clinical basis for diagnosing and treating intracranial infection caused by Nocardia. Methods　A case of pulmonary Nocardia asiatica complicated with brain abscess diagnosed at the Second Affiliated Hospital of Hainan Medical University was selected to analyze the clinical manifestations, cerebrospinal fluid characteristics, pulmonary and cranial imaging features, and treatment plan, and to summarize the diagnosis and treatment experience. Results　The patient was an elderly woman with a history of diabetes, dry cough was the first symptom without fever or headache. At the beginning of the course, it was diagnosed as pulmonary infection and tuberculosis in the local hospital, and received conventional antimicrobial and anti-tuberculosis therapies, but showed no improvement. The patient developed progressive limb weakness, followed by consciousness disorders, and coma. Cerebrospinal fluid (CSF) adenosine deaminase and lactate dehydrogenase were not abnormal, CSF pressure, protein and white blood cells were high, mainly with multiple nuclear cells. CSF glucose and chloride were normal in the early stage of the disease, but decreased significantly in the later stage. Metagenomic analysis of cerebrospinal fluid indicated Nocardia asiatica with a specific sequence number of 537. Lung CT showed exudation, abscess, and cavity in the right lung. Skull MRI scan + enhancement suggested multiple scattered abscesses in both cerebral hemispheres. The abscesses were of different sizes and showed ring enhancement, with extensive surrounding edema, and ventricular compression. After treatment with meropenem, linezolid, and compound sulfamethoxazole tablets, the cerebrospinal fluid recovered, and the lesions in the lungs and intracranial structures improved. Conclusions　Brain abscess caused by Nocardia asiatica is similar to the tuberculous brain in clinical symptoms, cerebrospinal fluid examination, craniocerebral imaging, so we should be alert to the possibility of Nocardia infection in patients with diabetes. At the same time, metagenomic testing of the cerebrospinal fluid can help confirm the diagnosis. The mortality and disability rates of brain abscess caused by Nocardia are high. Early diagnosis and treatment can improve the prognosis.

Follicle-stimulating hormone (FSH) is synthesized and secreted by the anterior pituitary, which binds to its receptors expressed on the membrane of Sertoli cells in the testis to bring about spermatogenesis. With the development of DNA sequencing technology, FSH SNPs rs10835638 and FSHR SNPs rs6165, rs6166, and rs1394205 were detected, which might directly affect the expression of FSH and activity of FSHR, resulting in male spermatogenic dysfunction. This review focuses on the relationship of FSH and FSHR gene polymorphisms with male infertility.

Objective To observe whether appropriate intermittent exercise at the ischemic threshold can safely promote collateral circulation in an ischemic area of the myocardium through the increased expression of vascular endothelial growth factor(VEGF)and its receptor fetal liver kinase-1(Fik-1). Methods A balloon constrictor was surgically implanted in the first obtuse marginal coronary artery(OM1)of miniature pigs.The subjects were divided into 3 groups:a sham-operation group,a pure ischemia group,and an exercise training group.Subjects in the exercise training group performed individualized treadmill programs 30 min daily,5 d per week,for 8 weeks,including 2 two-minute episodes of exercise-induced ischemia.Two pre-exercise episodes of pure ischemia induced by brief OM1 occlusion were also conducted.Only pure ischemia was induced in the pure ischemia group,and the sham-operation group remained sedentary for the experimental period.Relative myocardial blood flow(RMBF)was measured using microspheres.VEGF and Flk-1 expression levels were measured by Western blotting and real time RT-PCR analyses.Cardiac troponin I(ctnI)levels were determined using an enzyme-linked immunosorbent assay(ELISA). Light and electron microscopy were employed to examine myocardia damage in the ischemic area.Results RMBFs in the exercise training group were significantly higher than those in the pure ischemia and sham-operation groups. RMBFs in the pure ischemia group were significantly higher than those in the sham-operation group.The expression of VEGF and Flk-1 proteins and mRNAs in the exercise training group were significantly higher than those in the pure ischemia and sham-operation groups,and the levels in the pure ischemia group were also significantly higher than those in the sham-operation group.After training,no myocardial damage and no ctnI increase was observed in the pure ischemia group.Microscopy revealed no obvious structural changes. Conclusion Intermittent exercise at the isehemia threshold intension can safely promote coronary collateral formation through upregulation of VEGF and Flk-1 expression in the ischemic myocardial area of a porcine model.

Objective Intrahepatic biliary papillomatosis(IBP)is a rare disease that is characterized by multiple numerous papillary adenomas in the intrahepatic biliary duct(IBD).The clinical features and outcome,however,are not well known.The clinicopathologic features,treatments and follow-up results were retrospectively analyzed in order to improve the efficiency of diagnosis and treatment for the disease.Methods Between August 2006 and October 2008,9 patients were diagnosed with IBP by histological findings at a tertiary referral center,Ningbo Medical Center(University of Ningbo,College of Medicine,Ningbo,China).The authors retrospectively reviewed the medical records to obtain clinical,radiological and pathologic data.The therapeutic results and follow-up data were also reviewed.Results The ratio of male to female was 2:7 and the middle age was 59 years.Repeated episodes of fever and right upper quadrant abdominal pain with or without jaundice were the common clinical manifestations.There were intrahepatic choledocholithiasis and/or history of previous biliary operation in 8 cases.The level of CA19-9 and CEA were almost normal.Imaging workup demonstrated cyst-like dilatation of intrahepatic biliary tree with or without liver atrophy,which were more obvious in the mucin-hypersecreting IBP.All of the 9 cases underwent curative resection with an adequate resection margin.Macroscopic findings demonstrated that the tumors of 9 cases were all located in the left lobe with mucin-hypersecreting type in 7 cases.The diameter of numerous papillary granular was usually less than 10 mm(from 2 to 5 mm.frequently)and friable,that filled the dilated IHD dispersive.Fine fibrovascular cores lined by dysplastic epithelial cells were frequently found under microscope.Few foci of stromalinvasion were noticed in the two cases with malignant transformation.All of the 9 cases survived and there was no recurrence.Conclusion IBP occurs more often in middle and old women who have history of biliary disease. Repeated episodes of cholangitis are the common clinical manifestations. Extra- and intrahepatic biliary tract dilatation is the common imaging finding.MRCP/ERCP is more valuable than others in diagnosis. Clinical and histological finding shows that IBP is a premalignant disease with high malignant potential. Curative resection should be done as earlyas possible for the long-term survival rate. The use of cholangioscopy in operation and rapid biopsy of resection margin will benefit the curative resection.
