Objective To explore the expression and clinical significance of secretagogne (SCGN) in neuroendocrinal tumors.Methods Immunohistochemistry was applied for detecting expression of SCGN,chromogranin A (CgA),synaptophysin (Syn) and neuronspecific enolase (NSE) in 45 cases of neuroendocrinal tumors.The difference between the expression of SCGN and the remaining indicators were compared.And different expression profiles of SCGN between groups categorized by sex,age and degree of differentiation were also compared.Results The positive expression rate of SCGN,CgA,Syn and NSE in neuroendocrinal tumors was 95.56％ (43/45),100.00％ (45/45),46.67％ (21/45) and 88.89％ (40/45) respectively,and the differences among them were statistically significant(P ＜ 0.01).Expression of SCGN was not correlated with the patient's sex,age and degree of differentiation (P＞ 0.05).Conclusions Most cases of neuroendocrinal tumors are positive for SCGN and SCGN is more sensitive than CgA.Syn is the most sensitive one for diagnosis of neuroendocrinal tumors.SCGN can be seen as a novel neuroendocrinal marker in the clinical diagnosis of neuroendocrinal tumors.

BACKGROUND: The repair and functional reconstruction of peripheral traumatic nerves depend, on posttraumatic operation time and operative techniques which have certain referential value.OBJECTIVE: To explore the effects of related factors on the repair and functional reconstruction of common peroneal nerve (CPN) after injuries.DESIGN: A case analysis.SETTING: Department of Orthopaedics, Fourth Hospital Affiliated to China Medical University.PARTICIPANTS: Eighteen patients diagnosed with simple CPN injury received treatment in the Department of Orthopedic Surgery of the Fourth Affiliated Hospital, Chinese Medical University, between January 1991 and January 2001. There were 15 males and 3 females aged 12-61 years old with the mean age of 26.5 years; there were 9 cases of complete transection, 3 cases of incomplete transection, 1 case of compression, 4 cases of contusion, and 1 case of irreversible injury. Posttraumatic treatment at hospital was obtained 0.5 hour to 6 months after injury.METHODS: All patients were subjected to CPN explorative operation;neuroanastomosis was performed on 12 cases, neurolysis on 2 cases, tendon graft on 1 case and conservative treatment on 3 cases. Antibiotics were administered after operation together with blood activating medicine and neurotrophic medicine. Moreover, the patients were required to do passive functional exercise in order to avoid arkylosis and myoatrophy.MAIN OUTCOME MEASURES: Functional recovery of CPN was assessed at postoperative 6 months based on the myodynamia of the same side anterior tibia muscles (excellent: above grade 4; good: grade 3; passable: grade 2; poor: grade 1 or grade 0).RESULTS: All the 18 patients entered the results analysis; their outcomes were assessed as excellent in 10 cases, good in 6 cases, and passable in 2cases, with the excellent rate being 89% (16/18).CONCLUSION: Patients diagnosed with CPN injury should be treated with primary repair of traumatic nerves as early as possible, which will benefit the functional recovery of limbs.

Objective To study the benefits and drawbacks of endoscopic thyroidectomy via breast approach by using gasless anterior neck skin lifting method.Methods A total of 21 patients with thyroid diseases were enrolled in this study,including 16 cases of nodular goiter and 5 cases of primary hyperthyroidism.All the cases underwent endoscopic subtotal thyroidectomy through breast approach while the operational space was established by using an abdomen suspending device and 2 Kirschner pins to mechanically suspend and retract the anterior neck skin.Results The endoscopic subtotal thyroidectomy was completed successfully in all of the cases without conversion to open surgery.The mean operation time was 82.5 minutes(ranging from 57 to 125 minutes).Intraoperative blood loss was less than 20 ml.Post-operational recovery was satisfying in all the patients.Drainage volume averaged 80.6 ml(50 to 150 ml).The patients were followed up for 1 to 12 months after the operation,during which no complications occurred.Conclusions Endoscopic thyroidectomy via breast approach using gasless anterior neck skin lifting method is a safe and low-cost procedure.By using the method,CO2 insufflation-related complications can be avoided.Although the operational space established by this method is relatively small,the operation can be completed without much difficulies.

Objective This paper was conducted to study the preparation methods and the hypoglycemic effects of oral sodium alginate-insulin nanoparticles (INS-NPs) on the blood glucose level in Streptozotocin-induced diabetic Wistar rats. Methods The INS-NPs were prepared by an ionic gelation method. The changes of the morphology and size of the INS-NPs were examined by transmission electron microscope and Zetasizer 3000HS. The hypoglycemic effects of the INS-NPs were evaluated by monitoring the blood glucose levels in streptozotocin-induced diabetic Wistar rats. Results The INS-NPs were spherical or ellipsoidal in shape with a diameter of 236.4?19.3nm. The entrapment efficiency and load efficiency of INS-NPs were 78.5%?6.1% and 22.6%?4.4%, respectively. In vivo hypoglycemic study showed the levels of blood glucose of diabetic Wistar rats declined at 7h after oral administration of INS-NPs (26U/kg). Their hypoglycemic effects were maintained for 12h and the levels of blood glucose were kept with normal range for 6h (less than 7.0mmol/L). Conclusion The INS-NPs have the hypoglycemic effect on the blood glucose level of streptozotocin-induced diabetic rats.
