Objective:Based on the level evaluation model of tuberculosis control established by analytic hierarchy process model, put forward the method of comprehensive evaluation of the quality of tuberculosis(TB) control and prevention work.Methods: The evaluation target of tuberculosis disease control and prevention was analyzed using analytic hierarchy process. At the same time, the weight of each evaluation index was established by the comparison of the pairwise comparison judgment matrix. And 3 TB control institutions in Beijing were evaluated.Results:Using this model, the comprehensive evaluation index of 3 TB control institutions was 65.6, 54.2 and 57.7 respectively.Conclusion: Analytic hierarchy process is a combination of qualitative and quantitative analysis. It is comprehensive, flexible and simple. At the same time, it is a good method for the evaluation of tuberculosis control and prevention in hospitals, and can be used as an effective tool for the management of tuberculosis control and prevention.

Medullary thyroid carcinoma is a kind of neuroendocrine tumor that originates from calcitoninproducing parafollicular C-cells of the thyroid.Its incidence,diagnosis and treatment are unique.Ki67 is a nuclear antigen related to cell proliferation.It plays an important role in tumor occurrence and development,and it has important clinical significance in a variety of malignancies.Ki67 proliferation index has become classification index in neuroendocrine tumors of the gastrointestinal tract.In this paper,we review the study of medullary thyroid carcinoma and the expression of Ki67 in medullary thyroid carcinoma.

Objective To examine the association between baseline body mass index (BMI) and overall survival (OS) in lymph node negative breast cancer patients. Methods From Jan. 1st, 1998 to Dec. 30th, 2008, 662 patients with lymph node negative breast cancer were treated at the Breast Center of Peking University Peo-ple’s Hospital. The clinical factors such as menopause status, tumor stage, body mass index (BMI), total triglyc-eride (TG), total cholesterol (TC) and glucose (GLU) were collected. The chi-square test was used to assess the association between obese and other factors. Log-Rank test and Cox regression analysis were performed to make univariate and multivariate analysis. Results The median follow up was 82 months (ranging from 2 to 209 months). The 5-year and 10-year survival was 93% and 82%. Obesity was associated with GLU and tumor stage (χ2=5.224, P=0.031; χ2=6.007, P=0.14), whereas there was no relationship between obesity and other factors. The Log-Rank test revealed statistically significant better survival for non obesity (χ2=4.693, P=0.030), normal GLU (χ2=4.678, P=0.031) and HR positive patients (χ2=7.837, P=0.005). COX regression analysis showed that BMI (χ2=3.874, P=0.049) and HR status (χ2=6.782, P=0.030) had independent influence on overall survival of node negative breast cancer patients. Conclusion Obesity is an adverse prognostic factor for lymph node negative breast cancer patients, which may be associated with obesity-related disorders such as high blood GLU.

OBJECTIVE: To investigate the expression and clinical significance of Ki67 and calcitonin in medullary thyroid carcinoma(MTC). METHOD: The expression level of Ki67 and calcitonin was studied in 44 cases of medullary thyroid carcinoma tissue and 20 cases of adjacent nontumor tissue by SP immunohistochemistry. RESULT: The positive expression of Ki67 and calcitonin in medullary thyroid carcinoma tissue were 86.36% (38/44) and 100.00% (44/44) respectively. There was a significant difference between carcinoma and normal thyroid tissue (P<0.01). The overexpression of Ki67 and calcitonin in medullary thyroid carcinoma had no relationship with gender and age of patients,but had relationship with size of tumor,clinical staging and lymph node metastasis (P<0.05). Meanwhile, Ki67 and calcitonon had no significant correlation with each other. CONCLUSION The overexpression of Ki67 and calcitonin may play important role in occurrence, development and metastasis of medullary thyroid carcinoma. It may be used as an important judgement for the biological behavior of medullary thyroid carcinoma.

Papillary thyroid microcarcinoma (PTMC) is defined as a papillary thyroid carcinoma measuring less than 10 mm in diameter. With the development of ultrasonic technology and the popularization of physical examination, the incidence of PTMC increased dramatically. Routine preoperative diagnostic methods include clinical examination, thyroid ultrasound and fine needle aspiration biopsy. But its treatment methods are still controversal. In this paper, we review literatures in recent years and discuss the clinical common problems of PTMC.

Objective To investigate the safety and clinical effect of laparoscopic radical parametrectomy in the treatment of unexpected cervical cancer . Methods A retrospective analysis was made on clinical characteristics of 15 patients who were diagnosed as unexpected cervical cancer from January 2008 to December 2014.The age of the patients was between 29 and 67 years old, with an average of 43.9 years old.The indications for hysterectomy were cervical intraepithelial neoplasia (CIN) grade 2-3 in 7 cases, uterine myoma in 3 cases, dysfunctional uterine bleeding in 2 cases, uterine prolapse in 2 cases and adenomyosis in 1 case. Pathological results after the hysterectomy included 13 cases of cervical squamous carcinoma and 2 cases of adenocarcinoma .The lesions were all confined to the cervix , with 4 cases of stage ⅠA2 disease and 11 cases of stage ⅠB1 .The lymph-vascular space invasion was found in 4 cases.The operation interval between the two operations was 3-7 d (mean, 4.6 d).They were all given laparoscopic radical parametrectomy . Results The operation time was 212-285 min (mean, 249.6 min), and the blood loss was 250-500 ml ( mean, 376 ml) .Postoperative pathological findings showed no residual disease .Only one patient had left pelvic lymph node mestastasis .Two patients had intraoperative complications , including 1 bladder injury and 1 ureteral injury .There were 3 cases of postoperative complications , including 2 cases of uroschesis and 1 case of lymphocyst .The follow-up time was 6-84 months ( median, 48 months).No recurrence was seen.The 1-, 3-, 5-year survival rates were 100%, 93.3%, 86.7%, respectively. Conclusions Laparoscopic radical parametrectomy in the treatment of unexpected cervical cancer is difficult to perform and has more complications . This surgical method is applicable to those who refused postoperation radiotherapy or required retaining ovarian function .

Chemoradiotherapy is an important part in the adjuvant regimen for locally advanced gastric cancer after radical resection. Adjuvant chemoradiotherapy has demonstrated a clear local control and survival advantage for locally advanced patients with less than D2 lymph node dissection. Thus, chemoradiotherapy is recommended as standard of care in the postoperative setting. However, the role of radiotherapy for patients with more extensive D2 lymph node dissections remains controversial. Three phase III random-ized clinical trials in Asia show that adjuvant chemoradiotherapy after D2 dissection is safe and feasible and may benefit certain groups of patients. The benefit of radiotherapy in the case of more extensive surgery still warrants well-designed, fully powered randomized controlled clinical trials for verification. More studies are needed to focus on the identification of patient subgroups that are at high risk for locoregional failure and may benefit from adjuvant chemoradiotherapy. Further optimization of target volume in the radiother-apy and exploration of new modalities of radiation techniques are also necessary.

Comorbidity, which can affect the treatment and prognosis of its disease, has gradually caught attention from both at home and abroad. Although chronic obstructive pulmonary disease (COPD) mainly involved lung tissues, it may also cause the systemic (or extra-pulmonary) adverse effects. Many types of comorbidities existed in COPD. This article summarized the prevalence, risk factors and pathogenesis of comorbidities such as cardiovascular disease, osteoporosis, anxiety and depression, lung cancer, infection, metabolic syndrome and diabetes mellitus. It also con-ducted related studies on the diagnosis and treatment status and current problems of COPD comorbidities, which may provide evidences for COPD outcome evaluation.
