Fibulin protein family has widely existed in the extracellular matrix, and plays an important role in maintain the stable of basement membrane, elastic fibers and loose connective tissue. Fibulin-5 (FBLN-5) is one of the members of the Fibulin protein family, which is essential to the structure function and cell mediated action. The lack of FBLN-5 will cause many diseases such as internal organ deformity. Current research suggests that changes of expression level of FBLN-5 are associated with the occurrence of tumors such as lung cancer, and also can influence the tumor proliferation, invasion and prognosis, thus may become a new molecular marker for cancer diagnosis. Therefore, in this review, we summarize and update biological characteristics and functions of FBLN-5, and its role in the development of tumor formation mechanism.

Objective To investigate the genotype and antifungal susceptibility of AspergiIlus species isolated from clinical settings and environmental sources. Methods Random amplification of polymorphic DNA (RAPD) analysis was performed to profile the genotypes of 48 Aspergillus fumigatus strains, 59 Aspergillus flavus strains and 30 Aspergillus niger strains isolated from clinical settings and environmental sources. NCCLS M38-A protocol was carried out for antifungal susceptibility testing of these Aspergillus isolates. Results As RAPD analysis showed, the 48 Aspergillus fumigatus strains were classified into 8 genotypes, 59 Aspergillus flavus strains into 12 genotypes, and 30 Aspergillus niger strains into 5 genotypes. A significant difference was observed in the susceptibility to terbinafine among the 8 genotypes of Aspergillus fumigatus (χ2 = 33.092, P ＜0.01 ) as well as in that to amphotericin B among the 5 genotypes of Aspergillus niger (χ2 = 15.185, P＜ 0.05).No statistical difference was found in the susceptibility to amphoteriein B, itraconazole, fluconazole or flucytosine among the 8 genotypes of Aspergillus fumigatus or in that to terbinafine, itraconazole, fluconazole or flucytosine among the 5 genotypes of Aspergillus niger. Conclusion There is some difference in the susceptibility to some antifungal agents between different genotypes of Aspergillus fumigatus and Aspergillus niger.

Objective To evaluate the safety and efficacy of transrectal ultrasound guided prostatic nerve blockade for pain control during transrectal prostate biopsy.Methods Seventy-three patients requiring systematic 13 cores biopsy of the prostate were randomized into two groups.Group A(37 cases) received an injection of 5 ml 1% lidocaine into the prostatic neurovascular bundles on each side at the base of the prostate under ultrasound guidance,and group B(36 cases) received 5 ml saline ( 0.9% sodium chloride) at the same way.Pain during biopsy was assessed using a 10-point linear visual analog pain scale immediately after this procedure.Results The mean pain scores during transrectal prostate biopsy were significantly lower in group A than that in group B( 1.1? 0.6 vs 5.9? 3.1,t= 4.81,P

The effects of superoxide dismutase (SOD) on mitochondrial function after hypoxic and reoxygenated perfusions in isolated rat hearts were observed. Significant decreases in respiration control ratio (RCR) and ADP/O ratio (P/O) as well as activities of succinic dehydrogenase (SDH) and cytochrome oxidase (CCO) were found alter 40 minutes' hypoxia and 20 minutes' reoxygenated perfusion. Adding SOD to the perfusion fluid during the reperfusion period could restore the decreased mitochondfial function, which was shown by increased RCR and P/O as well as activities of SDH and CCO.

Objective:To study the effect of breviscapine on visual function of the patients with primary open-angle glaucoma after filtration surgery. Methods:Twenty-nine cases (42 eyes) of patients with primary open-angle glaucoma at middle and late stage after filtration surgery were selected and randomly divided into the experimental group and the control group according to the defect degree of visual field. The 15 patients (21 eyes) in the experimengtal group ( TG) were intravenously injected 250ml saline containing 50mg breviscapine, while the 14 patients (21 eyes) in the control group (CG) were intravenously injected 250ml saline containing 1g vita-min C. The treatment course was 2 weeks followed by one-week withdrawal. After three treatment courses, the visual function in the two groups was investigated and compared before and after the treatment. Results:After the treatment, the visual field defect value and the thickness of retinal nerve fiber layer of the patients in TG were both better than those before the treatment (P<0. 01,P<0. 05). The values of visual acuity and visual field defect of the patients in TG were significantly better than those of the patients in CG ( P<0. 05, P<0. 01). Conclusion:After intraocular pressure is controlled, breviscapine injection can reduce the vision damage of patients with primary open-angle glaucoma at middle and late stage after filtration surgery and improve the visual field defect.

Objective To evaluate the clinical significance of prostatic hypoechoic lesions on transrectal ultrasound(TRUS) for prostate cancer detection Methods 438 patients referred to our hospital between August 1999 and August 2006 for biopsy of the prostate.Every patient received 6～13 biopsy cores of the prostate.If a hypoechoic was identified,the biopsy was taken from this lesion.Correlation between hypoechoic lesions,isoechoic areas and cancer detection for each core was performed.Results Among 438 patients,cancer was detected in 112(25.6%) patients.Hypoechoic lesions were seen in 75(67%)patients with prostate cancer,the isoechoic areas in 37(33%).A total of 3504 biopsy cores were obtained from 438 patients.Among them,636 biopsy cores were taken from hypoechoic lesions.163(25.6%)biopsy cores taken from hypoechoic lesions harbored cancer and 473(74.4%) had no cancer.The cancer detection rate was similar in patients with hypoechoic lesions on TRUS or not,25.4%(75/298)and 26.4%(37/140)respectively.The difference was not statistically significant(P

Objective To report the first case of disseminated trichosporonosis in China.Methods A series of clinical,histopatholog ic,and mycologic studies were carried out in a 20year-old-female patien t,who had no definite underlying disease.The causative fungus was identified according to culture,biochemical t est and DNA sequencing.Results Abundant fungal spores,yeasts and h yphae were shown in the specimens tak en from infectious granulomas.The fungal c olonies in the culture of skin lesion s or crusts,liver,oral psedomembra ne,vagina,nasal cavity,urine,and sto ol were the same.The colonies exhibi ted creamy white to yellowish in colo r,rugose on the surface,and hyphae at t he periphery.Under microscopy,there were a lot of rectangular arthrospores,round or oval spores w ith or without buddings,as well as br anched and septate filaments.The isolated fungus was unanimously identified as Trichosporon asahii(No.AS 2.2174)through culture,bio-chemistry and molecular biology tests.The patient's condition was impr oved obviously after the combinatio n treatment of amphotericin B liposom e(Amphotec)and fluconazole.Conclusion The extensive and lasting systemic impairments caused by T.asahii have scarcely been reported at home a nd abroad.Combination therapy with amphotericin B and fluconazole is effective.

Objective To explore the experience in diagnosis and treatment ot primary transitional cell carcinoma of prostate for the early and accurate to diagnosis and treatment.Methods The clinical data and features of 3 cases were retrospectively reviewed.Results All patients were diagnosed as primary transitional cell carcinoma of prostate.Two cases were advanced tumor.The preoperative examinations (ultrasound and serum,PSA) have failed to accurately indicate the diagnosis.All of them were confirmed by pathological examination.1 case lost follow-up,1 case performed TURP + chemotherapy through intravesical administration have survived 17 months respectively till today.The other case has already survived 2 months postoperatively but with lumbar spine bone metastasis.Conclusions Early diagnosis of primary transitional cell carcinoma of prostate is difficult.The diagnosis of the disease depends on the transrectal needle biopsy of the prostate or the specimens of the prostate after the Urethroscopy.Because of the prognosis is bad,and prone to pathological missed diagnosis or misdiagnosis.Need to exclude multicentric lesions and mixed tumor and choice of treatment method.

Objective To evaluate the clinical significance of prostatic hypoechoic lesions on transrectal ultrasound (TRUS) for prostate cancer detection.Methods Four hundred and thirty-eight patients referred for biopsy of the prostate from August 1999 to August 2004. Every patient received 6-13 biopsy cores of the prostate. If a hypoechoic was identified, the biopsy was taken from this lesion. Correlation between hypo-echoic lesions, isoechoic areas and cancer detection for each core was performed. Results Among 438 patients, cancer was detected in 112(25.6%). Hypo-echoic lesions were seen in 75 (67%) patients with prostate cancer, the isoechoic were as in 37 (33%). A total of 3504 biopsy cores were obtained from 438 patients, and 636 biopsy cores were taken from hypoechoic lesions. Among 636 biopsy cores, 163 (25.6%) were cancer and 473(74.4%)were not. The cancer detective rate in patients with hypoechoic lesions (75/298, 25.2%) was similar to non-hypoechoic lesions (37/140, 26.4%) on TRUS. There was no statistically significant difference between them (P
