Endophytic fungi which reside in the tissue of mangrove plants seem to play an important role in the discovery of new biologically active substances. During the course of screening for the antimicrobial metabolites from the endophytic fugus Penicillium sp. FJ-1 of mangrove plant Avicennia marina, a new aurone glycoside (1) was isolated by repeated column chromatography on silica gel and recrystallization methods. The structure of 1 was elucidated as (Z)-7,4'-dimethoxy-6-hydroxy-aurone-4-O-β-glucopyranoside, on the basis of spectroscopic analysis. Compound 1 exhibited antifungal activity against Candida sp., with the potency comparable to amphotericin B and much better than fluconazole. Compound 1 can also inhibit extracellular phospholipase secretion in a concentration-dependent manner.

Objective To study the diagnosis and treatment of testicular cancer in cryptorchids. Methods The data of 10 patients with cryptorchid tumor treated at our hospital between 1986 and 2003 were retrospectively analyzed.Their average age was 40 years (range,32~55 years).Of these patients,1 had the testis in the inguinal area;3,in the scrotum (with a history of inguinal cryptorchidism) and 6,in the abdomen.Cryptorchidism occurred on the left in 2 cases,on the right in 5 and bilaterally in 3.Three patients presented with stage Ⅰ A disease,5 with stage Ⅰ B,and 2 with stage Ⅱ D. Results All the 10 patients received surgical treatment including radical tumor resection,radical tumor resection with retroperitoneal lymph node dissection (RPLND),and palliative operation.Pathology showed that 9 cases had seminoma and 1 had seminoma accompanied by embryonic carcinoma.Radiotherapy was performed in 8 cases,and radiotherapy plus chemotherapy,in 2 (including 1 with embryonic carcinoma).Postoperatively,6 patients were followed up for 6 months to 14 years with a mean of 5.2 years;these patients showed no evidence of tumor recurrence and metastasis. Conclusions Cryptorchid testes have a greater risk of malignant change than do normally descended testes,and early intervention is advocated to prevent malignant canceration.Even treated with orchidopexy or orchiectomy,the patient should be followed up lifelong.Most of cryptorchid tumors are seminomas, and the ideal treatment strategies are tumor resection and radiotherapy.

ObjectiveTo study the effects of intermittent subglottic secretion drainage(SSD)with an endotracheal tube on incidience of ventilator- associated pneumonia(VAP). MethodsWe searched computerized databases,including Cochrane library,Pubmed,EMbase,CBM,CNKI,Wanfang and some relevant databases from initializing to March 2012,extracting data about subglottic secretion drainage(SSD)with an endotracheal tube on incidence of VAP using RCT.The data had Meta- analysis by software RevMan5,and to those data which could not be conversed or merged,they underwent descriptive analysis. ResultsWeidentifled 5 randomized clinical trials that met the inclusion criteria with a total of 683 randomized patients.In Meta- analysis,the overall risk ratio for ventilator- associated pneumonia was decreased significantly by intermittent subglottic secretion drainage with an endotracheal tube.There was no significant difference on adverse events or on hospital or intensive care unit mortality.Databases,including ICU and hospital LOS,duration of endotracheal catheterization,bacteria concentration,which were difficult to be conversed and obtained full data,they underwent a descriptive research. ConclusionsCompared with the common endotracheal tubes,the use of endotracheal tubes with subglottic secretion drainage is effective for prevention of ventilatorassociated pneumonia.But it has no effect on adverse events or on hospital or intensive care unit mortality.So large sample RCTs with multiply- center should be carried out to assess the effect of the use of SSD.
