Objective Effects of exercise training and Chinese Medicine Compound for Invigorating Qi and Tonifying the Kidney on testicular StAR and P450 SCC mRNA expression in rats were observed. Methods 50 Wistar rats were randomly divided into 4 groups: sedentary control group(SC, n=10), sedentary with medicine group (SM,n=10), training group(T, n=15) and training with medicine group(TM, n=15). After 6 weeks swimming training , serum testosterone level of rats were tested through radioimmunological method; using RT-PCR, we measured testicular StAR and P450 SCC mRNA levels of rats. Results (1) In T group, serum testosterone level was lower than that in SM and TM groups. Whereas, compared with SC group, the serum testosterone level in TM group kept steadiness. (2) In T group, the gene expression of StAR was markedly lower than that in SC control (P

Objective: To investigate the effects of soy hydrolysed peptides supplementation on small intestinal morphology and nitrogen absorption in rats,and illustrate the characteristic of absorption on soy hydro? lysed peptides supplementation in small intestinal. Methods: 30 male SD rats were randomly divided into three groups: Placebo group (water supplemented, Pla group); Isolated soy protein-supplemented group (Pro group); Soy hydrolysed peptides-supplemented group (Pep group). After one week meals adaptation, Metabolic test had done, small intestinal morphology, and the activity of aminopeptidase were determined. Results: (2) The content of intestinal epithelial protein in Pep group increased 48.60% than Pro group, and increased 91.37% than Pla group (P

Objective To explore the feasibility and value of treating esophageal thoracic fistula with covered esophageal stent through nasal esophagus drainage tube. Methods Seven patients with esophageal thoracic cavity fistula were enrolled and treated by 5F pigtail side-holes catheter inserting into thoracic cavity for drainage and then again through nasal esophagus and fistula, placing a covered stent in the esophagus to occlude the orifice of the fistula. The abscess cavities were washed and radiographied periodically through drainage tubes. Results The insertion of the drainage tube and the placement of covered stent were all successful. The drainage tubes were placed in abscess cavities for 12-22 days, average 15 days. The radiography through drainage tubes showed that the abscess cavities disappeared or shrank obviously with control of hydropneumothorax before the drainage tubes being pulled out. The esophagogram after withdrawal of the drainage tubes notified that the fistulae were occluded satisfactorily with stents expanded fully without displacement and stenosis. Conclusions Treating esophageal thoracic cavity fistula with covered esophageal stent through nasal esophagus drainage tube is feasible and safe with clinical efficiency.

Objective To investigate the clinical features and the management of primary pigmented nodular adrenocortical disease PPNAD) and to evaluate its relationship with Carney complex. Methods One case of PPNAD reported. The patient was a 52 years oldmale. He was hospitalized because of hypertension for one year. The patient had a Cushing's face with elevated plasma and urine cortisone levels which could not be suppressed by both low dose and high dose dexamethasone tests. Ultrasonography howed normal bilateral adrenal glands. CT scan found a 1.6 cm × 2.0 cm mass in the left adrenal gland and normal on tralateral adrenal gland. Results The patient had accepted left laparoscopic adrenalectomy. The pathological examination onfirmed the diagnosis of PPNAD. Micro scopic study showed that there were black-gray spots in the center of the specimen. Hyperplasia was found in all the three adrenal zones. Lipofuscin was observed in the cytoplasm of reticular zone cells. The patient's blood pressure had returned to normal level after the surgery. Conclusions PPNAD is a rare type of ypercortisolism. As there is no specific feature in clinical manifestation and radiological examination of this disease, it is very easy to make a misdiagnosis in clinical practice. PPNAD itself can be the comorbidity of Carney complex, careful differentiation is needed.
