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.

A canine model of electro-physiologic-electropharmacologic testing on ischemic ventricular tachyarrhythmias were established in the open-chest dogs subjected to programmed electrical stimulation (PES) on 5~8days after acute my-ocardial infarction produced with two -stage occlusion of left anteriol decending coronary artery (LAD) followed by partly reperfusion. The electrophysiologic -electropharmacologic effects of pro-cainamide (PA ) were observed in this canine model. pA distinctly lengthened the QTc interval and the effective refractory period ( ERP) of normal and infarct myocardium in both ventricles and decreasedthe dispersion of ERP in infarct myocardium (IDR) as well as the dispersion of ERP in left ventricle (VDR). The PES - induced ventricular tachycardia (VT) or ventricular fibrillation (VF) was prevented in 5 out of 6 PA treated dogs (n = 6),Normal saline (NS) did not prevented PES- induced VT/VF. The results suggest that PA may be effective in preventing the onset of reentrant ventricular tachyarrhythmias after myocardium ischemic damage.

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.
