Methods Data were collected from 94 patients with BAC (including 67 cases with pure bronchioloalveolar carcinoma, 16 cases with BAC by local infiltration and 11 cases with adenocarcinoma having BAC character). All patients were proved pathologically bronchioloalveolar carcinoma from January 1989 to December 2003. Clinical features, characteristics of radiology, methods of treatment and survival status were studied retrospectively. Surgical treatment and efficacy approaches according to different TNM stages and clinical patterns were also analyzed. Results Ninety-eight patients underwent complete resection and 4 underwent palliative operation and 2 underwent exploratory thoractomy. The 1-, 3-, 5-year survival rates were 75.5 %, 53.2 %, 41.5 %. According to international staging system of lung cancer, there were marked difference in stage Ⅰ group, stage Ⅱ group and stage Ⅲ group (P <0.01). According to pathological classification, there were marked difference in pure bronchioloalveolar carcinoma, BAC with local infiltration and adenocarcinoma having BAC character (P <0.01). Conclusion Bronchioalveoar carcinoma is a special form of lung cancer. It has its own characteristics on biology,radiology,clinic or pathology. Lobectomy is performed commonly in patients with bronchioloalveolar carcinoma. It may be concluded that the early diagnosis, early therapy are the key points for improving the survival rate of BAC.

Objective:To explore the expression of mammalian target of rapamycin (mTOR)and its relationgship with the prognosis of breast cancer,and to provide evidence-based basis for the using of mTOR inhibitor in the treatment of breast cancer.Methods: A systemical literature search was conducted based on the following databases:PubMed,EMBbase,Cochrane Library,ISI Web of Science,and CNKI up to November 24,2015.The outcome measures were hazard ratio (HR)with 95% confidence interval (CI) for the association between the mTOR expression and the prognosis of patients with breast cancer.The primary end points including disease-free survival (DFS ), and overall survival (OS ). STATA 12.0 was used to conduct the statistical analysis. Results:A total of seven cohort studies,1 758 patients were included. The risk of recurrence and metastasis of the breast cancer patients with positive expression of mTOR was 2.05 times of the patients with negative expression of mTOR (HR= 2.05, 95% CI: 1.01 - 4.13,P = 0.003);the risk of death in the breast cancer patients with positive expression of mTOR was 2.63 times of the patients with negative expression of mTOR (HR = 2.63, 95%CI:1.45-4.80,P = 0.736).Conclusion:The positive expression of mTOR can significantly increase the recurrence,metastasis and death risk of the patients with breast cancer.

This study was aimed to observe bronchial asthma patients in remission after treatment of traditional Chi-nese medicine(TCM) with four diagnostic information, syndrome differentiation and changes oflung function indicators, in order to explore the efficacy evaluation with TCM characteristics. TCM tongue manifestation instrument, TCM in-quiry scale, pulse-taking instrument, acoustic diagnostic information collection system, and spirometer were used in thecollection of 33 bronchial asthma cases in remission before and after treatment (1~5 months) basedon four diagnos-tic information and lung function indexes. Single-factor analysis of variance and other methods were used in the analysis of four diagnostic parameters and lung function indexes before and after treatment. The results showed that after TCM treatment, there were significant changes on indexes such as facial complexion, tongue sub-region color, color of tongue coating and other parameters. There was significant difference in the acoustic parameters before and after treatment. After TCM treatment, the frequency of lung system symptom such as nasal obstruction was decreased. There was no significant difference on changes of pulse-taking indexes among asthma patients before and after treat-ment. After treatment, the FEV1.0% of asthma patients was increased,whichindicated that asthma ventilatory function had been improved to some extent. It was concluded that TCM objective test provide an effective basis for the diag-nosis of bronchial asthma on aspects such as TCM syndrome, disease change observation and clinical evaluation.

Objective To explore the expression of Survivin in colorectal cancer tissue and its relationship with clinicopathological features.Methods In situ hybridization was used to examine the expression of Survivin mRNA,and immunohistochemical method was used to detect the expression of Survivin protein in 60 cases of colorectal cancer and 30 cases of colorectal normal mucos tissue.The relationship of the expression of Survivin protein with clinicopathological features of colorectal cancer was analyzed.Results The positive expression rate of Survivin protein in colorectal normal mucos tissue (10.00％,3/30) was lower than that in colorectal cancer tissue (73.33％,44/60),and there was significant difference (P ＜ 0.05).The positive expression rate of Survivin mRNA in colorectal normal mucos tissue (6.67％,2/30) was lower than that in colorectal cancer tissue (63.33％,38/60),and there was significant difference (P ＜ 0.05).The expression of Survivin mRNA was positively correlated with depth of invasion,lymph node metastasis,liver metastasis,peritoneal micrometastasis and TNM stage in patients with colorectal cancer (P ＜ 0.01),but had no correlation with gender,age,tumor size,location,degree of differentiation and histological type (P ＞ 0.05).Conclusions The specific high expression of Survivin protein has a high correlation with the occurrence,development,infiltration of colorectal cancer.Survivin may be used as a marker for prognosis of patients with colorectal cancer.

Objective:To observe the effect of Er Chen Tang on CYP2E1 and mitochondrial energy metabolism in nonalcoholic fat-ty liver disease ( NAFLD) to explore the role of Pinellinae Rhizoma Praeparata ( PRP) and Citri reticulatae pericarpium ( CRP) in the treatment of nonalcoholic fatty liver disease. Methods:Er ChenTang and the prescription without PRP or CRP was respectively given the animal models by gastric gavage. The serum levels of ALT, AST, triglyceride, cholesterol, SOD and MDA in hepatic tissue, and the contents of liver tissue CYP2E1 and ATP were detected in the mice. Results:The CYP2E1 levels in NAFLD mice increased signif-icantly with abnormal mitochondrial energy metabolism. Compared with those in the model group, the levels of ALT, AST, triglyceride and cholesterol were significantly reduced by Er Chen Tang, meanwhile, the content of CYP2E1 was reduced and also restored liver en-ergy metabolism. The treatment effect significantly decreased when the lack of PRP or CRP, and the ability of restoring liver mitochon-drial energy metabolism of Er Chen Tang decreased significantly when the lack of PRP (P<0. 05). After the removal of CRP, the in-hibition ability of Er Chen Tang to CYP2E1 levels significantly decreased (P<0. 05). Conclusion:Er Chen Tang can effectively im-prove nonalcoholic fatty liver diseases, and effectively reduce the content of CYP2E1 in liver tissue of mice and restore the mitochondri-al energy metabolism.
