Objective To investigate the prognostic effect of quantity of lymph node(LN)resected in operations of patients with stage Ⅰ non-small cell lung cancer(NSCLC).Methods The clinical, pathological and follow-up data of 74 patients with stage Ⅰ NSCLC who were treated with surgery from January 1998 to December 2002 Beijing Friendship Hospital, Affiliated to Capital Medical University were reviewed retrospectively.Grouping the patients, according to the quantity of lymph node resected, the Kaplan-Meier method and Cox proportional hazards model was used for univariate analysis and multivariate analysis of factors with prognostic effect.Results The five year survival rate and disease-free survival(DFS)rate of these 74 patients were 64.9% and 47.3%.The univariate analysis showed that tumor size(P =0.016),T-staging (P =0.008)and extent of lymph node dissection(P =0.013)could influence the survival rate.The 5-year OS and DFS rates of patients with less than 6 LNs resected were less than the other group(more than 6 LNs)apparently.The multifactorial analysis indicated that other than staging, the quantity of lymph node resected was also an influence factor of prognosis.Conclusions The OS rate of patients has positive correlation with quantity of lymph node resected in operations.Six LNs must be resected leastways in operations of patients with stage Ⅰ NSCLC.

Objective To investigate the pathological features,diagnosis and treatment of primary malignant melanoma in esophagus (PMME).Methods The clinical data of 3 patients with PMME who were admitted to the Beijing Friendship Hospital from January 2008 to June 2009 were retrospectively analyzed.All the patients received esophageal barium radiography,electronic fiberesophagoscopy,esophageal endoscopic ultrasonography,computed tomography,and underwent surgery.Adjuvant therapy and immunotherapy were applied postoperatively.Results The results of barium radiography showed irregular filling defect presentation in the distal esophagus.The results of endoscopy showed a purple black tumor with a length of 3-8 cm in the esophagus.The results of endoscopic ultrasonography showed that the tumor was derived from the mucosal layer with low echo density.The results of computed tomography showed thickness of the lower segment of the esophagus.All the 3 patients received left thoracic approach esophagectomy and esophagogastrostomy.Histopathology and immunohistochemistry confirmed malignant melanoma.The expressions of Mart-1,HMB-45 and S-100 antigen were positive.The survival time of 2 patients was longer than 3 years,and 1 patient died of metastasis 6 months after operation.Conclusions PMME is a kind of rare and malignant tumor with dismal prognosis.Surgical management is the first choice,adjuvant chemotherapy and immunotherapy are hopeful to increase the survival time of the patients.

We expierenced two cases of intradural verteral artery dissecting aneurysms. The presenting symptom was subarachnoid hemorrhage in one case and ischemic symptom in the other. The preoperative angiographic finding typically showed fusiform dilatation and proximal and/or distal narrowing of the affected artery. In one case, the vertebral artery was clipped distal to the PICA and in the other case trapping was performed through the extreme lateral transcondylar approaches. This approach permits a control of the aneurysm through the direct view of whole length of the vertebral artery, lower cranial nerves and ventral brain stem. In order to obtain ample view and to save the lower cranial nerves and perforating vessels, jugular tubercle should be sufficiently drilled out. Postoperitive neurological outcomes were favorable except mild hoarseness for some period in trapping case.

The aim of this study was to investigate the effect of Bu-Shen-An-Tai recipe (BSATR) and its two components (Bushen recipe, and Huoxue recipe) on endometrial morphology during peri-implantation in superovulated mice. Mice were randomly divided into five groups, including the normal (N), model (M), Bushen (BS), Huoxue (HX) and Bu-Shen-An-Tai (BH) groups. The uteri were collected on day 4 of pregnancy, and the endometrium thickness, microvessel density (MVD) and number of pinopodes observed. Compared with the M group, the endometrial thickness in the BS, HX and BH groups was significantly increased and there was a significant difference in endometrial thickness between the BS and the BH groups. The mean MVD was significantly lower in the M group than in the N group, and there was a significant increase in MVD in the BS, HX and BH groups as compared with the M group. Compared with the M group, the pinopode scores in the endometrium were significantly increased in the HX and BH groups; and the BS group had significantly higher pinipode scores than the HX and BH groups. In conclusion, the results of the present study demonstrated that the recipes (Bushen, Huoxue and BSATR) could improve the endometrial environment by regulating the endometrial thickness, MVD and the number of pinopodes at the window of implantation. Moreover, the Huoxue recipe and the BSATR were more efficient than the Bushen recipe, with the BSATR tending to have the most beneficial effects.

OBJECTIVETo study the role of different lymphadenectomy in the treatment of selected clinical-stage IA non-small cell lung cancer.
METHODSAll 115 postoperative patients admitted from January 1997 to May 2002 with pathologic-stage T1 who had been preoperatively diagnosed as clinical-stage I A non-small cell lung cancer were divided into a radical systematic mediastinal lymphadenectomy (LA) group and a mediastinal lymph node sampling (LS) group. Impacts on morbidity, N staging, overall survival (OS) and disease-free survival (DFS) were evaluated in each group respectively. Associations between clinical-pathological parameters (age, sex, tumor location, tumor size, pathological type and lymph node metastases) and OS, DFS were analyzed. The cumulative OS and DFS was calculated by the Kaplan-Meier method and compared by the Log-rank test.
RESULTSThe mean number of dissected lymph nodes was (15.98 +/- 3.05) in LA group and (6.48 +/- 2.16) in LS group with a significant difference (P < 0.01). No statistically significant difference existed in modification of N staging, OS and DFS between LA group and LS group. However, for patients with lesions of a diameter more than 2 cm, 5-year OS in LA group was significantly higher than that in LS groups (LA vs. LS = 78.2% vs. 54.5% ,P < 0.05), also 5-year DFS was significantly higher (LA vs. LS = 75.1% vs. 51.3%, P < 0.05). For patients with lesions of 2 cm or less, 5-year OS and 5-year DFS were similar in both groups. The early surgery-related parameters (duration of surgery, drain secretion and morbidity) indicated a slighter invasion in LS group. In addition, patients with large cell carcinoma and adenosquamous carcinoma were associated with significantly poor 5-year OS (P < 0.05) , and patients with lymph node metastases were associated with poor 5-year OS as well as 5-year DFS (P < 0.01).
CONCLUSIONSAfter being intraoperatively identified as T1 stage, patients with lesions of more than 2 cm in clinical-stage IA non-small cell lung cancer should be performed with LA to get a better survival, and patients with lesions of 2 cm or less should be performed with LS to decrease invasion.

PURPOSE: We evaluated the usefulness of a CT guided percutaneous transthoracic cutting needle biopsy (PCNB) using a 20 gauge (G) needle for pulmonary lesions after a comparison with the use of an 18 G needle for diagnostic accuracy and complications. MATERIALS AND METHODS: From August 2005 to July 2007, 433 patients underwent a CT guided PCNB. A total of 191 patients were excluded from the study as these patients had benign lesions seen after PCNB, but did not receive a confirmation biopsy or undergo follow-up (> 1 year). We evaluated the diagnostic accuracy for the use of PCNB using the Chi-squared test and analyzed which factors (location and size of lesions, diameter of the needle, distance between the pleura and lesions, presence or not of emphysema) were related to occurrence of a pneumothorax after PCNB using a multi-variant regression test. RESULTS: The diagnostic accuracy for malignant lesions with the use of an 18 G and a 20 G needle were 95.4% and 97%, respectively. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for the use of an 18 G needle were 95.7 %, 100%, 100%, and 91.6%. The sensitivity, specificity, PPV, and NPV were 97.8%, 100%, 100%, and 95.0% for the use of a 20 G needle. A pneumothorax occurred in 5.5% (24/433) of the cases and was closely related to the distance from the pleura to the lesions. CONCLUSION: CT guided PCNB with the use of a 20 gauge needle provided good diagnostic accuracy and the procedure is safe to perform.
