Objective:To investigate the overexpression of Stat3 and Cyclin D1 in laryngeal neoplasm with immunohistochemistry method.Method:With immunohistochemistry method, we investigated the expression of Stat3 and Cyclin D1 in laryngeal neoplasm and analysis the relationship between Stat3 and clinical pathological factor.Result:Stat3 and Cyclin D1 overexpressed in laryngeal neoplasm tissue and they have positive relationship.Conclusion:Active Stat3 may promote the transcription of target gene Cyclin D1,which could accelerate carcinomatous change.

Objective To investigate the morbidity,clinical feature,diagnosis and therapy of ovarian disease in children.Methods Eighty-two children with ovarian disease were admitted and treated in Nanjing children's hospital from Jan.1992 to Jan.2007,were analyzed retrospectively with age,emergency admissions or not,dwell,pathology and method of operation.Results The age of 82 patients ranged from 1 day to 14 years old and the mean age was 6.7 years old.Thirty-one cases(37.8%) were emergency admissions and 51 cases(62.2%) were routine admissions.Twenty-seven cases(32.9%) were rural patients and 55 cases(67.1%) were urban patients.Forty-five cases(54.8%) were nontumorous disorder,31 cases(37.8%) were benign tumor and only 6 cases(7.4%) were malignant tumor.About the morbidity,12 patients(14.6%)were admitted from 1992 to 1996,24 patients(29.5%) from 1997 to 2001 and 46 patients(55.9%) from 2002 to 2007.Chemotherapy were carried out in 6 cases with malignant tumor in internal medicine,2 cases with sexual precosity kept observation,the others were cured.Conclusions Ovarian disease can occur at any age in children.The clinical manifestation is characterized mainly by acute abdomen.The incidence of ovarian disease of children in urban areas is higher than that children in rural areas.The morbidity continues to show an upward tendency and the pathologic manifestations are mostly benign,laparoscopic operation has obviously superiority.

Objective To evaluate the safety and efficacy of the technique of transoral Orvil EEA stapler (OrVil) for laparoscopic gastrectomy of gastric cancer in our hospital.Methods Between Sep 2012 and Aug 2013,73 patients at our department underwent open (n =36) or laparoscopic (being reconstructed by OrVil,n =37) gastrectomy.Early surgical outcomes of the two groups were compared to assess the effectiveness,security and postoperative complications of OrVil procedure.Results The two groups had similar mean numbers of dissected lymph nodes (29 ± 10 vs.31 ± 14,t =-0.697,P =0.488),lengths of postoperative hospital stay (14 ± 5 vs.12 ± 3 d,t =1.933,P =0.057) and postoperative complications (11 vs.11,P =0.939).Intraoperative blood loss was significantly less (189 ± 79 vs.343 ± 90 ml,t =-7.782,P =0.000) and time to first flatus significantly shorter (2.9 ±0.5 vs.3.5 ±0.6 d,t =-4.714,P =0.000) with the use of OrVil.Operation time of laparoscopic group was significantly longer than that of open group (266 ± 97 vs.204 ± 39 min,t =3.607,P =0.001).There was one each anastomotic leakage in both groups.Conclusions With the suitable approach and skillful technique,OrVil is a technically safe and feasible surgical procedure for the treatment of gastric cancer.

OBJECTIVE To study the frequencyof extracapsular spread (ECS) in neck metastasis and its impact on prognosis in supraglottic carcinoma. METHODS A total of 177 patients with radical or modified neck dissection between Jan. 1994 and Dec. 1997 for supraglottic carcinoma were summarized. Transparent lymph node detection and a series of sectioning method were applied on all neck dissection specimens. The SPSS software package (version 11.5) was used to make statistical analysis. Survival curves were calculated with the Kaplan-Meier model. Impact of extracapsular spread on prognosis was assessed for significance with the Log-Rank test. RESULTS Eighty one patients were pathologically positive in neck specimens and the neck metastatic rate was 45.8 %. ECS was found in 32 cases and the ECS frequency was 39.5 % (32/81). The ECS was related with pathological N stage and the number of positive nodes. Patients with ECS had a higher possibility of regional recurrence and contralateral metastasis. The 5-year survival rates of patients with neck metastasis ECS- and patients with ECS+ were 61.9 % and 22.2 % respectively. The differences had statistically significance. CONCLUSION ECS in neck metastasis affects the prognosis in patients with supraglottic carcinoma. If bilateral neck dissection was not selected simultaneously, close follow-up on contralateral neck should be selected in patients with ECS because of a higher incidence of contralateral neck metastasis.

BACKGROUND:Can adipose-derived mesenchymal stem cells be used to treat sensorineural deafness caused by hair celldegeneration and loss? OBJECTIVE:To investigate the effect of adipose-derived mesenchymal stem cells from guinea pigs transplanted via the scala tympani on the recovery from sensorineural hearing in an animal model. METHODS:Intraperitoneal injection of gentamicin was performed to prepare sensorineural deafness models in guinea pigs. Then, adipose-derived mesenchymal stem cells from guinea pig were transplanted via the scala tympani. After 1 and 3 weeks, auditory brainstem responses were detected to observe the hearing variation after adipose-derived mesenchymal stem celltransplantation. Meanwhile, the migration and distribution of EDU-labeled adipose-derived mesenchymal stem cells in the cochlea were traced. RESULTS AND CONCLUSION:After 1 and 3 weeks of implantation, the results from auditory brainstem response showed that the hearing was gradual y improved. At 1 week of implantation, most of the cells were distributed in the perilymph and some cells migrated to the Corti organ and attached to the basement membrane. At 3 weeks of implantation, cells migrated and attached to the basement membrane of Corti organ, furthermore, some cells migrated to the cochlear nerve. The longer the time of implantation, the less cellsurvived. The results indicate that adipose-derived mesenchymal stem cells from guinea pig that are transplanted via the scala tympani can directly migrate and survive ultimately to improve the hearing.

ObjectiveTo explore the clinical results of endoscopic resection of the frontal benign tumors.MethodsNineteen cases of benign tumors in the frontal area were rcsected using endo scopic techniques.The tumors were diagnosed as benign according to complaint,history and physical examination.ResultsAll 19 tumors were totally resected.The pathological examination revealed 11cases of lipoma,3 cases of sebaceous cyst,3 cases of sebaceous cyst and 2 cases of dermoid cyst.During 6 months to 2 years of follow-up,no tumor recurred.Local concavity was noticed in all patients but all resolved within 6 months except 2 patients.They received granular fat graft of the concavities 6months late and were satisfied with the results.ConclusionsBenign tumors near eyebrows and in glabella area can be treated by minimally invasive endoscopic technique.Compared with traditional surgery,this technique offers inconspicuous scar and fast recovery.

OBJECTIVETo investigate the types, clinical features and therapeutic approaches of congenital anomalies of the vagina.

METHODSThe clinical data of 81 patients with congenital anomalies of the vagina were analyzed retrospectively.

RESULTSThere were 5 types in these 81 patients, and 16 (19.7%) patients showed absence of the vagina, 15(18.5%) had vaginal obstruction, 10 (12.3%) had transverse vaginal septum,14(17.2%) had longitudinal vaginal septae,18(22.2%) had septum obliquus, and 8 (9.8%) had imperforate hymen. Forty-eight (59.2%) patients presented with primary amenorrhea, and 22(27.1%) complained of irregular pelvic pain. Fifteen of the patients with absent vagina underwent amnion artificial vaginoplasty, and the others were treated with incising and removing the septum, all having good clinical outcomes.

CONCLUSIONAmnion artificial vaginoplasty is a good option for treatment of absent vagina.
