With the development of proteomics, the application in the research for the function of proteins becomes popular. This review article presents that proteomics, a kind of tools of molecular biology, has been successfully used for studying the pathogenesis of type 1 and type 2 diabetes.

Surgery is the first choice for the treatment of early non-small cell lung cancer(NSCLC),and lymph node metastasis is the most important factor influencing prognosis of resectable NSCLC.A large number of studies have identified the importance of systematic mediastinal lymph node(N2) dissection,which is also an important basis for the development of NCCN guidelines.But there are few reports about the dissection of intrapulmonary lymph node(N1),especially no detailed study on the dissection of the lymph nodes around the bronchi of non-primary tumor-bearing lobes and segments in lung cancer,and the NCCN guidelines were not detailed elaborate.This article will make a summary of the research on the correlation of intrapulmonary lymph node(N1) dissection.

Objective To analyze the clinical and pathological characteristics of thyroid carcinoma in patients from Qilu Hospital of Shandong University in last 7 years,and to explore the changes in disease spectrum.Methods Records of 772 patients with thyroid carcinoma,who underwent thyroidectomy and pathological examination,were reviewed from January 2005 to December 2011.Results (1) Individuals suffering from thyroid carcinoma have increased rapidly during these 7 years.(2) The high incidence of the disease resided in the age group of 30-59 for both men and women,with a male-to-female ratio of 1 ∶ 2.73.(3) The proportion of papillary microcarcinoma showed a growing trend,the rising trends were also apparent in papillary thyroid cancer (PTC) coexisting with nodular goiter or Hashimoto's thyroiditis (HT).Papillary microcarcinoma accounted for27.27％ of all PTC in 2005 and reached 54.22％ in 2011.Coexistence of PTC and HT accounted for 12.38％ of the cases with a male-to-female ratio of 1 ∶ 6.Conclusion The occurrence of thyroid carcinoma,especially papillary microcarcinoma has been increasing in recent years.The coexistence of PTC with nodular goiter or HT showed a trend to increase.

In order to evaluate the effect of chinese medicine (Yi Qi Xiao Zheng decoction) in reducing radiation side effect, an observation of peripheral blood WBC, stem cell amount, the function of liver and renal in mice was made during and after radiation.The results showed that WBC and stem cell amount were higher in Chinese medicine combined with radiation group than radiation only group after 3 fraction radiation(P

Objective To compare effect of chemotherapy agent DDP to MACS in sorting cancer stemcells (CSC) of laryngeal carcinoma cell line Hep-2. Methods CD133 magnetic beads were applied to sort Hep-2 cells. Different dosages of DDP were used to treat Hep-2 cells for 48 hours. Enrichment rate of CD133+ cells by MACS and after DDP treatment was detected by Flow Cytometer (FCM). Morphologic change was observed under inverse-phase microscope. Results FCM showed that the sorting rate of CD133+ cells through MACS was 64.33 %, while after DDP treatment for 48 hours, the rate of CD133+ cells was enriched significantly in each dosage of DDP, with the maximal rate was 50.7 %, in the dosage of 4 μg/ml. There was a significantly difference between MACS and each of DDP group (P <0.01). Cells treated with DDP were abnormal in morphology. Conclusion MACS and DDP sorting has respective advantages in enriching CSC in Hep-2 cell lines.

Objective To compare the clinical effect of povidone-iedine cream plus vagina scrubbing with traditional preoperative vaginal preparation method in order to seek a more safe,effective,convenient and efficient method to prepare the vagina.Methods 100 cases of married patients undergoing elective gynecological surgery were divided into the observation group and the control group with 50 patients in each.The observation group adopted povidone-iodine cream plus vagina scrubbing and the control group used traditional method.Two groups were prepared in the vagina before and after taking cervical swabs for bacterial culture to compare the positive rate of bacterial culture.Results Intra-group comparison of vaginal bacterial culture before and after vaginal preparation was significantly different,but no statistical significance was seen between the two groups.Conclusions Vagina preparation with povidoneiodine cream plus vagina scrubbing can not only reduce the workload of nurses but also improve patient comfort degree.
