Objective To improve the diagnosis and treatment of testicular masses associated with congenital adrenal hyperplasia(CAH).Methods A 25-year-old man presented with bilateral testicular nodules.Physical examination revealed palpable multiple nodules in the bilateral testes and epididymides as well as enlarged and hard right testis with uneven surface.Biochemical examination showed testosterone(T) of 18.7 nmol/L,17?-(OH)P＞20.0 ng/ml,positive results of rapid ACTH stimulation test and dexametha- sone suppression test.B-ultrasound demonstrated diffuse testicular lesions with nodules in parts of the bilater- al testes.Bilateral testicular nodules were biopsied,and pathological diagnosis was interstitial cell hyperplasi- a.Positive staining for?-inhibin was observed immunohistochemically.The clinical characteristics of testicular masses associated with CAH were reviewed in combination with the literature.Results Based on medical history,imaging,laboratory and pathologic examinations,the patient was diagnosed with testicular masses as- sociated with CAH.He received oral cortisol at dose of 40 mg daily for 2 weeks,and then at dose of 30 mg daily as maintenance therapy.After treatment of 8 months,B-ultrasound showed complete regression of the testicular tumors.Follow-up of 24 months showed no recurrence of the tumor.Conclusions For patient with bilateral testicular masses,endocrinological evaluation and clinical history taking are indicated to exclude testicular interstitial cell hyperplasia associated with CAH.By oral steroid replacement therapy,hormone-sen- sitive testicular masses can regress.

To study the stimulation effect to the growth of Bifidobac te rium sp. A04, 4 kinds of oligosaccharide, 8 kinds of Chinese traditional medi cine and 4 kinds of food raw materials were used. The results indicates that so ya bean oligosaccharide is the most effective (P

Using isoeugenol as the sole carbon source,a novel strain,producing high amounts of vanillin from isoeugenol,was isolated from soil.According to the physiological and biochemical characteristics and its 16S rRNA gene sequence analysis,it was identified as Bacillus fusiformis.The initial results showed that 4.20 g/L vanillin was obtained by bioconversion of 2% isoeugenol with Bacillus fusiformis.

PKS gene was screened by PCR from thirty strains of spone-associated bacteria including twenty-one actinomycetes isolated from Craniella anstrialiensis and nine bacillus isolated from Dysidea avara in the South China Sea.As a result,a 669 bp KS domain gene was successfully amplified from Bacillus C89.BLAST analysis showed that the KS domains were most closely related to the KS sequences of Bacillus subtilis subsp.subtilis str.168 with 96% similarity.Phylogenetic analysis demonstrated the KS domain belong to trans-AT KS domains.This study demonstrated the existence of PKS gene in bacteria associated with sponge Dysidea avara for the first time,and provided proof for the hypothesis that sponge-associated bacteria are perhaps the true producers of many novel bioactive compounds in sponge.Meanwhile,this study lays a basis for the microbial screening for polyketide compounds production.
