One marine actinomycete strain FIM02-523 was isolated from marine soil in the East China Sea in Fujian Province. The fermentation broth of strain FIM02-523 exhibited potent antitumor activities. Strain FIM02-523 grew well on most media tested, the colonies were orange to dark brown but lacked aerial hy-phae, no diffusible pigments were observed. Phylogenetic, chemotaxonomic, morphological analyses, physiological and biochemical characteristics demonstrated that strain FIM02-523 belong to the genus Mi-cromonospora, may be a strain of the type species Micromonospora chalcea.

To observe the proliferation of T lymphocytes stimulated by CML and AML cells which were induced by rhGM-CSF and rhIL-4, and the secretion of IFN-gamma from proliferated T lymphocytes, the expression of CD80, CD86 and HLA-DR on CML and AML cells induced by GM-CSF and IL-4 was assayed by flow cytometry in vitro. Then one-way mixed lymphocyte reaction was carried out, with induced leukemia cells as stimulating cells and auto-T lymphocytes as reactive cells. The secretion of IFN-gamma from T lymphocytes was determined by double antibody sandwich ELISA. The results showed that GM-CSF and IL-4 significantly upregulated the expression of CD80, CD86 and HLA-DR on CML cells and CD80 and CD86 on AML cells, which could stimulate the T lymphocyte proliferation and high secretion of IFN-gamma (in CML group) of autologous T lymphocytes. It is concluded that the CML and AML cells induced by GM-CSF and IL-4 have the ability to present tumor specific antigen to auto-T lymphocyte.

Objective To study the changes of biochemical markers of bone turnover and bone mineral density (BMD) in mid- and old-aged women.Methods A total of 408 female volunteers aged 40 to 86 years were enrolled.Serum bone alkaline phosphatase (BAP),osteoealtin and urine type I collagen N-telopeptide(uN'TX) were measured using ELISA,and BM D at anteroposterior lumbar spine 1-4(L1-4)and femoral neck (FN) was detected by dual energy X-ray absorptiometry (QDR4500A).Results (1) Serum BAP,osteocaltin and uNTX levels were positively correlated with age,parity,number of births and duration of menopause (all P

Aim To study mRNA and protein expression of eNOS in pulmonary tissue of chronic hypoxic pulmonary hypertension(HPH)rats and chronic hypoxic rats treated with novel KATP opener iptakalim.Methods sixty Sprague-Dawley(SD)male rats were randomly divided into control group, hypoxic group, low dose iptakalim group(0.75 mg·kg~(-1)·d~(-1)), and high dose iptakalim group(1.5 mg·kg~(-1)·d~(-1)).Except the first group, the other three groups were put into hypoxic and normobaric chamber (10%±0.5% O_2,8 h/day and 6 day/week) to establish chronic hypoxic model. After four weeks, the mean pulmonary arterial pressure(mPAP), RV/(LV+S)and the plasma concentration of NO were measured. RT-PCR was performed to analyze the mRNA expression of eNOS in pulmonary tissue. Western blot was performed to analyze the protein expression of eNOS, iNOS in pulmonary tissue. Results ① The level of mPAP and RV/ ( LV + S) were significantly higher in the hypoxic group than those in control group ( P < 0. 05 ) , Low dose iptakalim groupandhighdoseiptakalimgroupdecreased the level of mPAP and RV/( LV + S) significantly (P <0. 05). ② The level of NO was significantly lower in the hypoxic group than those in control group (P<0. 05). Low dose iptakalim group and high dose iptakalim group increased the level of NO significantly (P < 0. 05 ). ③ The mRNA and protein expression of eNOS in the hypoxic group were significantly lower than those in the control group (P < 0. 05 ). Low dose iptakalim group and high dose iptakalim group increased the expression of eNOS significantly ( P < 0. 05). High dose iptakalim group was more significant. Conclusion Pulmonary vascular endothelial dysfunction is induced by chronic hypoxia,and the level of NO, the mRNA and protein expression of eNOS are decreased. Iptakalim can improve the vascular endothelial dysfunction, increase the expression of eNOS and the level of NO and reverse hypoxic pulmonary hypertension.

Objective To assess the strain and synchronism of left ventricular papillary muscles (PM) in functional mitral regurgitation (FMR) patients using two-dimensional speckle tracking echocardiography,and to explore the relation of PM function and the development of FMR.Methods Sixty ischemic cardiomyopathy patients with FMR and 60 idiopathic dilated cardiomyopathy patients with FMR were prospectively recruited.They were divided into three groups as the degree of FMR,patients with mild FMR was group F1,with moderate FMR was group F2,with severe FMR was group F3.Control group involved 42 healthy volunteers.The longitudinal peak strain of anterior and posterior PM (ALS,PLS),the peak time of longitudinal peak strain (APT,PPT),and the delay time of peak value between ALS and PLS (DT) were quantified.Results The ALS and PLS decreased company with increased of FMR degree (P ＜ 0.05,respectively),whereas the DT increased (P ＜ 0.05,respectively),and there was no significant variation trend of the APT and PPT.There was no intergroup difference of ALS and PLS,APT and PPT (P ＞ 0.05,respectively).ALS,PLS had negative correlation with LVM (P ＜ 0.05,respectively),and positive correlation with LVEF (P ＜0.05,respectively).DT had positive correlation with LVM(P ＜ 0.05),and negative correlation with LVEF (P ＜ 0.05).Conclusions The dysfunction and desynchronization of PM are closely related to the severity of FMR.The results may helpful to screen proper patients for cardiac resynchronization treatment.

Objective To assess the clinical efficiency , safety and potential advantages of autologous blood transfusion (ABT) drains compared with the closed-suction/no drainage. Methods Pubmed, Embase, Cochrane Library, CBMdisc, CNKI, VIP and WANGFANG were searched comprehensively. The statistical anal-ysis was conducted by using the Cochrane Collaboration review Manager 5.3.5. Results The pooled data of seventeen RCTs including a total of 1 993 patients showed that the patients in the ABT drainage group might benefit from the low rate of blood transfusion [ 16 . 59% and 37 . 47%, OR: 0 . 28 ( 0 . 14 ~ 0 . 55 ); 13 . 05% and 16.91%, OR: 0.73 (0.47 ~ 1.13), respectively]. The ABT drainage and the closed-suction drainage/no drainage have the similar clinical efficiency and safety length of hospital stay and wound infection on days 3 post-operative haemoglobin. Conclusion This systematic review provides the evidence that the ABT drainage offers a safe and efficient alternative to CS/no drainage with the lowered blood transfusion rate.

Objective To explore the outcome of modified bladder neck reconstruction in treating the urinary incontinence due to the sphincter dysfunction.Methods Between January 2010 and December 2014,a total of 23 patients,including 16 male and 7 female cases,with incontinence due to sphincter dysfunction had undergone a procedure of modified bladder neck reconstruction.The mean age was 36 years (range 17-61 years).Etiology of incontinence was secondary to pelvic fracture and urethral rupture procedure in 19 patients and other failure procedures in 4 cases.The mean duration of incontinence was 2 years (range 1-5 years).Urodynamic examination was performed in all patients and the mean maximum urethral pressure was 34 cmH2O (range 21-43 cmH2O).The modified bladder neck reconstruction was performed in 23 patients.Under the general anesthesia and vertical bladder incision,triangular mucosal strips,from the bladder neck to ureteral office,were denuded and leaving the central urethral plate,which was 2.0-2.5 cm in width.In order to form a neourethra and bladder neck,the multilayer triangular muscles were sutured interruptedly over a 14-16 F catheter using 2-0 or 3-0 polyglactin.And the anterior wall of the bladder was then closed over the new bladder neck using continuous sutured.Results The 23 patients were followed up for 6 months to 3 years,mean 1.4 years.Continence achieved in 5 patients.Of them,2 patients had difficulty in voiding but corrected by indwelling the catheter for another 2 weeks.Social continence was achieved in 7 patients.Incontinence status was improved in 7 cases and failed in 2 cases.Urodynamic examination was performed in 4 patients and the mean maximum urethral pressure was 64 cmH2O (range 52-72 cmH2O).Conclusions Our study suggested that the modified bladder neck reconstruction was a good procedure for the treatment of urinary incontinence due to sphincter dysfunction,particularly for the incontinence secondary to the traumatic urethral stricture or other operation.
