Anorexia Nervosa(AN),one kind of eating disorder charactered by abnormal eating patterns,low body weight,and weight and shape concerns,is an intractable psychiatric illness which has the highest mortality rates.The etiology of AN is complex,and the neurobiology mechanisms of AN remain unclear.Much of the research provided indications that the pathogenesis of AN is associated with the oxytocin (OT) functions.Summarizing the recent advances on OT in AN,a systematic review of OT research was conducted that it pertains to regulation of feeding,social activity,emotion and bone metabolism in AN.OT probably play an important role in the development and progression of AN.OT system disorder may be an state indicator rather than a trait indicator of AN.Because of the variety physiological effects and the complex effects on AN,OT has the potential applications,especially for the treatment of AN.

砄bjective: To study the mineralization and related differential phenotype of human dental papilla cells in vitro . Methods: Human dental papilla cells were primarily cultured with explant technique, the cells of third passage were incubated for a long term in the presence of 10 mmol/L ? glycerophosphate(? GP)and 50 ?g/ml of ascorbic acid (L AA) in DMEM containing 5% FBS. Alkaline phosphatase (ALP) and osteocalcin(OC) were measured at different culture time. Cell growth was observed under inverted microscope and mineralization was tested with Von Kossa stainning. Results: Cultured papilla cells were growing in multilayer. Cells exposed to ? GP and L AA exhibited higher ALP activity in 14 days and increased OC in 21 days with certain amount of secreted matrix. After 35 days of culture, mineralized tubercles were formed. ALP activity and synthesized OC began to decrease after 42 days of culture. Conclusion: Human dental papilla cells may show odontoblast phenotype in vitro .

Objective: To investigate the expression and distribution of G protein and protein kinase C (PKC) under the mechanical pressure in rabbit mandibular condylar chondrocytes (MCCs) and to study the role of G protein in PKC signalling pathway. Methods:MCCs from two-week-old New Zealand rabbits were cultured. After treatment under continuous pressure of 90 kPa for 60 min or 360 min by hydraulic pressure controlled cellular strain unit, the expression of G?q/11 protein was examined by Western Blot. The expression and distribution of PKC was observed by immunocytochemical staining. Results:Gaq/11 protein in MCCs treated by 90 kPa for 60 min and 360 min was increased by 163.7% and 65.8% respectively(P0.05). PKC in control cells distributed uniformly in the cytoplasm. After been pressed under 90 kPa for 60 min,PKC translocated to the membrane and, partly,into nuclei. When the pressure prolonged to 360 min, PKC distributed uniformly again in cytoplasm. By treatment of G protein inhibitor, the translocation of PKC under 90 kPa of 60 min was not observed. Conclusion:Feasible pressure may promote G protein expression and activate PKC. The activation of PKC signalling pathway is mediated by G protein.

Objective To evaluate the applicative value of fiberoptic ductoscopy(FDS)in abnormal nipple discharge.Methods A total of 104 patients with nipple discharge were examined by fiberoptic ductoscopy(Germany Scholly Fiberoptic Gmbh 42.0500).The results were compared with postoperative pathological diagnosis.Results All the 104 cases were successfully diagnosed with FDS.The detectable rate for intraductal mass by ductoscopy is 94 %(49/52).The sensitivity and specificity of ductoscopy for mammary duct cancer is 50%(1/2)and 91%(43/47)respectively;the negative predictive value is 98%(43/44),positive predictive value is 20%(1/5),and accuracy is 90%(44/49).Five cases of papillomatosis were diagnosed by ductoscopy,in which 3 cases were consistent with postoperative pathological findings,therefore the diagnose accordance rate is 60%;the other 2 cases were proven to be multiple papilloma.Thirty-eight cases of papilloma were detected by ductoscopy and received lobectomy of bresat;55 cases of inflammatory duct disease did not receive any operation;and 3 cases(3%,3/104)were diagnosed papilloma by re-examination with ductoscopy due to persistent nipple discharge,and were confirmed after operation.Conclusions Fiberoptic ductoscopy is the first choice for examination of nipple discharge for its accuracy in finding pathogenic cause and locating lesion,and surgery can thereby be avoided for galactophoritis and mammarv duct ectasia patients.

Objective To evaluate the value of breast duct endoscopy and breast localization needle for the diagnosis and microinvasive treatment of intraductal lesions. Methods A total of 103 patients with nipple discharge without breast lumps were examined by breast duct endoscopy in our hospital. Of them, 63 cases of intraductal lesions were localized with breast localization needle and received arc incision of the areola of the breast and excision of the localized breast duct with 1-cm adjacent tissues, which were sent for intraoperative frozen. After the frozen pathological examination, the operation was ended for the patients with intraductal papilloma; simple mastectomy was performed on those with duct papillomatosis; and simple mastectomy combined with DIEP reconstruction was carried out for the patients with intraductal carcinoma. Results Frozen and postoperative pathological examinations showed single intraductal papilloma in 59 of the patients (59/63, 93.6%), duct papillomatosis in 2 (2/63, 3.2%) , and intraductal carcinoma in 2 (2/63, 3.2%). The 59 patients with single intraductal papilloma were reexamined in 3 months after the operation, none of them had nipple discharge or other symptoms. Conclusions Resection of intraductal lesions under the guidance of breast localization needle is less traumatic with good cosmetic outcomes. By using the method, high rates of complete resection and accuracy of pathological examination can be achieved.

Objective To study clinical effects of lavage treatment for inflammatory breast diseases guided by color Doppler sonography.Methods The lesions of 63 patients with inflammatory breast diseases (30 of breast abscess,20 of plasma cell mastitis,13 of breast chronic sinus)were positioned by color Doppler sonography.Surgical debridement and lavage catheter treatment were performed under general anesthesia.Results 54 patients were healed by first intention,and they were satisfied with their breast shapes.4cases of mammary abscess,3cases of plasma cell mastitis and 2 cases of breast chronic sinus had relapse within half a month.Conclusions Color Doppler sonography guided lavage treatment of inflammatory breast diseases is simple with significant healing effect,fast recovery speed,less recurrence and high cure rate.The operation had little pain to patients and small hidden postoperative scar.The breast shapes are nice-looking.
