Objective To explore the expression of p130Cas and c-erbB-2 in human breast carcinoma and the relationship between p130Cas and c-erbB-2 levels with clinical and pathological characteristics. Methods Immunohistochemistry SP staining was applied to detect the expression of p130Cas and c-erbB-2 in tumor tissues from 53 cases of human primary breast carcinoma,10 cases of breast fibroadenoma and in 10 cases of normal breast tissues. Results Breast carcinoma tissues showed higher levels of p130Cas and c-erbB-2 than normal and fibroadenoma tissues(both P＜0.01).The expression of p130Cas was related with age, menopausal status, ER, PR status and histological grades, but not related with tumor size, lymph node status and pathological stages. The expression of c-erbB-2 was related with ER status, histological grades and lymph node status, but not related with age, menopausal status, PR status, tumor size and pathological stages. There were no significant correlations between p130Cas and c-erbB-2. Conclusion p130Cas and c-erbB-2 have relations with the malignant transformation and differentiation of breast carcinoma.c-erbB-2 is associated with metastasis of breast carcinoma.p130Cas and c-erbB-2 can be served as useful indicators in the prognosis of breast carcinoma.

Objective To investigate the electrophysiological characteristics of the ventralis intermedius nucleus (Vim) in order to find an easy and safe way to confirm the target in Vim-thalamotomy. Method In microelectrode-guided selective Vim-thalamotomy for 23 Parkinson's disease patients, the background activity, amplitude and discharge frequencies of Vim were compared with its surrounding structures. The response of kinesthetic neuron and tremor cell to microstimulation was also compared. Result There were differences in backgroud activity and discharge amplitude for Vim, ventralis lateralis nucleus (VL), ventralis caudalis nucleus (VC), and internal capsule. Based on the response to active or passive movement of contralateral limb tremor cells were divided into two subgroups, which were different in localization. Contralateral tremor showed different response when the two subgroups of tremor cells were mircrostimulated. Conclusion The anterior border of Vim was easily found by microrecording. Only by combining microstimulation with microrecording could the posterior border of Vim and its interior and lateral ordination of target were identified exactly and safely. Kinesthetic neurons and tremor cells which responded to the movement of contralateral limbs should be destroyed.

Objective To investigate the application v al ue of stereotactic vacuum-assisted core needle breast biopsy (Mammotome biopsy) for breast masses and the surgical treatment for atypical ductal hyperplasia (AD H) detected by the Mammotome biopsy. Methods Ultrasound guide d Mammotome biopsies and corresponding surgical management were carried out in 3 2 patients (39 lesions) in this hospital between March 2003 and January 2004. Results Of the 32 patients (39 lesions), fibroadenosis was diag nosed in 24 patients (31 lesions), plasma cell mastitis in 1 patient, atypical d uctal hyperplasia in 4 patients, and breast cancer, 3 patients. Of the 4 patient s with atypical hyperplasia, a re-operation was conducted and a confirmative dia gnosis of atypical hyperplasia was made in 2 patients, while the oral administra tion of Tamoxifen was given in 1 patient with mild atypical hyperplasia and in 1 patient with moderate to severe hyperplasia. Conclusions For patients with severe ADH detected by the Mammotome biopsy, a re-operation is req uired. For patients with mild to moderate ADH: if the breast mass is palpable pr eoperatively, a surgical excision is recommended; if the patient has non-palpabl e masses with negative family history, in condition that the lesion has been ent irely removed, the surgery is not necessary and the oral administration of Tamox ifen with regular follow-up is indicated.

Objective To explore the expression of p130Cas and paxillin in human breast carcinoma and to investigate the relationships of p130Cas and paxillin levels with clinical and pathological characteristics.Methods SP immunohistochemistry staining was applied to detect the expression of p130Cas and paxillin in tumor tissues from 53 cases of primary breast carcinoma,10 cases of breast fibroadenoma and in 10 cases of normal breast tissues.Results Breast carcinoma tissues showed higher levels of p130Cas(P

OBJECTIVE: To investigate the possibility of thyroidectomy/lobectomy without drainage after surgery. METHOD: Eighty-eight consecutive cases with thyroid mass have been underwent operations including: lobectomy group(42 cases), thyroid lobectomy with contralateral partial thyroidectomy group (17 cases) and total thyroidectomy group (29 cases) from 2013. 06 to 2014. 06 in Nanjing Tongren Hospital. FIfteen patients with thyroid operation in other hospital were collected from 2014. 01 to 2014. 06, the recovery of postoperative incision were compared. RESULTS: Eighty-four cases were smoothly discharged from hospital except 4 thyroidectomy cases suffered from a small amount of effusion in surgical cavity. Our postoperative wound recovery were more in line with the principle of cosmetology compared with other hospital operation group. CONCLUSION Drainage following thyroidectomy is not essential, if the thyroid surgery is meticulous in each step of the surgery, and can increase the effect of beauty.

Objective To investigate the pathological features of chronic inflammation in prostatic specimens,and study the correlation of chronic prostatic inflammation with prostate cancer and hyperplasia of prostate in the elderly.Methods The histopathologic features of prostatic specimens which were taken during prostatectomy were retrospectively observed.The inflammatory cells in partial cases were labeled by immunohistochemical markers such as CD3,CD20,CD4,CD8,CD117 and CD138,and by inflammation related factors such as nuclear factor(NF)-κB,(COX-2),tumor necrosis factor-α(TNF-α)and inducible nitric oxide synthase (iNOS).Results The chronic prostatic inflammation of different extent were found in 100 patients with prostate cancer and 76 patients with benign prostatic hyperplasia,among them 71 cases (40.3 ％) had mild chronic prostatic inflammation,80 cases (45.5 ％) had moderate chronic prostatic inflammation,25 cases (14.2 ％) had severe chronic prostatic inflammation.Inflammatory cells mainly were CD3-labeled lymphocytes,accompanied by a small amount of mononuclear cells and mast cells.Chronic prostatic inflammation was not correlated with prostatic carcinoma and its differentiation degree,benign prostatic hyperplasia,focal atrophy and its subtypes,and high grade prostatic intraepithelial neoplasia (all P＞ 0.05).There was correlation between chronic prostatic inflammation and expression of COX-2 (P＜ 0.05).Conclusions The histological chronic inflammation is common in the prostate specimens in elderly men.There are no direct correlations of prostatic inflammation with prostatic carcinomas and benign prostatic hyperplasia.Prostatic inflammation is positively correlated with the expression of COX 2,which may be associated with the activation of COX-2 pathway induced by oxidative stress.

Objective To evaluate the feasibility and efficacy of chemoradiotherapy for locally advanced (inoperable) rectal cancer. Methods Seventy-six patients with locally advanced (T_4) or recurrent rectal cancer were randomized into two groups of concurrent chemoradiotherapy with either oxaliplatin plus 5-FU (oxaliplatin 130 mg/m~2, day 1,5-FU 350 mg/m~2, day 1 -5 ,LV 200 mg/m~2, day 1 -5, 4 weeks per cycle) or capecitabine (1650 mg/m~2, day 1 -14, 3 weeks per cycle) alone. All patients received pelvic three-dimensional conforrnal radiotherapy (3 DCRT) of 46 -50 Gy in 23 -25 fractions, with a boost of 14 -18 Gy in 7 -9 fractions. Results The median follow-up time was 19 months. The overall response rate was 64% in the oxaliplatin/5-FU group comparing with 58% in the capecitabine group (χ~2 = 0. 08 ,P =0. 772), with the median survival time of 22 months and 18 months (u = 17.71, P = 0. 077), respectively. The overall survival in the two groups was 68% and 63% at 1 year, and 21% and 19% at 2 years, respectively (χ~2 = 0. 97, P = 0. 326). There were no treatment-related deaths or grade 4 toxicities. Neutrocytopenia (39. 5% vs 77.7%, z = -3.97,P =0. 0001), diarrhea (47.4% vs 88.9%, z = -4. 78, P = 0. 0001), nausea and vomiting (68.4% vs 97.2%, z = -3. 17, P = 0. 0001), and neurotoxicity (5.3% vs 66.7%, z= -6.56, P= 0.0001) were more common in the oxaliplatin/5-FU group. Conclusions Concurrent chemoradiotherapy is well-tolerated and effective in patients with locally advanced (inoperable) rectal cancer.

Objective:To investigate the theraputic effect of STAT3 Decoy-ODN combined with chemotherapy drugs for HCC commonly used in clinical,include doxorubicin (DOX),5-fluorouracil (5-Fu) and cisplatin;and,analyzing the impact of combination therapy on the immune system.Methods:MTT assay was used to detect cell proliferation,and Annexin-V /7AAD double staining assay was used to detect the apoptosis of Decoy ODN transfected-hepatoma cells treated with chemotherapy drugs.The tumor growth and survival rate of H22 tumor-bearing mice treated with DOX combined with STAT3 Decoy-ODN or not were observed.FACS was applied to analyze the subpopulation and activation of PBMCs from tumor-bearing mice treated as above,and to evaluate the influence of DOX or DOX-treated tumor cells on spleen lymphocyte activation.Results: DOX-induced the suppression and the apoptosis of H22 were significantly increased by Decoy ODN transfection.The combination treatment of Decoy ODN and DOX significantly reduced H22 tumor growth and extended the survival of tumor-bearing mice.Low-dose DOX could increase the proportion of T cells and CD69+T cells in PBMCs,as well as the expression of CD107a and IFN-γin NK cells.DOXt-reated H 22 cells increased the proportion of T cells.Conclusion:Targeted blocking STAT3 could enhance the sensitivity of liver cancer cells to doxorubicin.So,combination therapy may improve DOX therapeutic effect and reduce DOX-mediated side effects.Furthermore,low dose of DOX can promote the activation of host immune system by acting on tumor cells.

ObjectiveTo verify the safety and feasibility of retroperitoneal laparoendoscopic singlesite surgery (LESS) adrenalectomy in the treatment of adrenal gland tumors or cyst.MethodsFrom Oct.2009 to Jan.2012,7 patients underwent retroperitoneal LESS adrenalectomy with Quadport technology by one surgeon.The mean patient age was 46 ( 39 - 55 ) years.The mean largest tumor diameter was 2.3 (1.8-3.6) cm.All procedures were performed through retroperitoneal approach by using Quadport,tip flexible laparoscope with 0° lens and conventional laparoscopic instruments.This technique was evaluated in respects of operative time,estimated blood loss,intraoperative complications,drainage time,visual analog pain scale (VAPS) score,post-operative hospital stay and pathological results.ResultsSeven cases of LESS adrenalectomy were completed successfully.There was no additional trocar added,no conversion to conventional laparoscopic or open approach.The mean operative time was 106 (70 - 180) min,and the mean estimated blood loss was 59 (5 -200) ml.The mean first day post-operative VAPS score was 2 (1 -3),drainage time was 2 (2 -3) d.Post-operative hospital stay was 5 (3 -6) d.No perioperative complication was observed.Pathological results showed 1 case of adrenal pheochromocytoma,5 cases of adrenal cortical adenoma and 1 case of adrenal cyst.ConclusionRetroperitoneal LESS adrenalectomy is a safe and feasible option for the treatment of adrenal tumors and cyst.

Objective To verify the safety and feasibility of applying laparoendoscopic singlesite radical prostatectomy (LESS-LRP) in the treatment of prostate cancer. Methods From Sept. to Dec. 2010, LESS-LRP was used to treat 2 early stage prostate cancer patients. The LESS-LRP was preformed through extra-peritoneal approach by using standard laparoscopic instruments and a 5 mm flexible laparoscope. This technique were evaluated in respects of operative time, estimated blood loss, intraoperative complications, drainage time, post-operative pain score (VAPS), post-operative hospital stay, pathological results and post-operative PSA levels. Results All procedures of the 2cases were completed with LESS-LRP without conversion to standard laparoscopic or open radical prostatectomy. The operative times for LESS-LRP were 280 and 285 min, estimated blood loss were 400 and 200 ml, respectively. There was no severe intraoperative complication. The drainage times were 2 and 6 d, the VAPS in the first post-operative day were 1 and 0, and post-operative hospital stay were 14 and 7 d. There was no secondary bleeding or wound infection. The 2 prostate cancer cases were all in pathological stage pT2c N0 M0. Surgical margins of the specimens were negative. The first case showed PSA of 0. 033 ng/ml 1 month after the surgery. Conclusion LESS-LRP can be an exploratory option in clinical for the treatment of prostate cancer.
