The correlation between infections by human papillomavirus types 6/11 and 16/18 and mammary gland hyperplasia with glandular thickening.

The aim of the present study was to investigate the correlation between human papillomavirus (HPV) type 6/11 and 16/18 infections and glandular thickening mammary gland hyperplasia in order to explore methods for preventing glandular thickening mammary gland hyperplasia. A total of 240 patients with glandular thickening mammary gland hyperplasia who were treated by surgery in our hospital from January 2012 to June 2017 were enrolled in the present study. The hyperplastic breast tissue and adjacent normal breast tissue were taken to test HPV type 6/11 and 16/18 infections using conventional PCR and in situ hybridization techniques. The correlations between HPV type 6/11 and 16/18 infections and glandular thickening mammary gland hyperplasia were analyzed using statistical methods of chi-square test. The infection rates of HPV type 6/11 and 16/18 in the hyperplastic breast tissue were 31.95% and 34.91%, respectively and 11.83% and 14.79% in the normal breast tissue, respectively. The differences were statistically significant (all p<0.05). HPV type 6/11 and 16/18 infections may be closely related to the development of glandular thickening mammary gland hyperplasia, and may be one of the causes of glandular thickening mammary gland hyperplasia.

Relationship between inflammatory factors and carotid atherosclerosis in OSAHS patients with type 2 diabetes mellitus / 重庆医学

Objective To investigate the relationship between serum inflammatory cytokines and atherosclerosis in type 2 diabetic patients with obstructive sleep apnea hypopnea syndrome (OSAHS).Methods One hundred and three patients with type 2 diabetes were divided into OSAHS group (OSAHS group) and type 2 diabetes mellitus group (non-OSAHS group) according to the results of polysomnography(PSG),and 35 healthy subjects were selected as control group.Serum levels of total cholesterol,triglyceride,fasting plasma glucose(FPG),glycosylated hemoglobin(HbA1c),tumor necrosis factor-α(TNF-α),high-sensitivity C-reactive protein (hs-CRP) and carotid intima-media thickness (IMT) were measured,and their relationship with OSAHS were analyzed.Results The waist circumference,BMI,FPG,HbA1c,IMT,TNF-α and CRP in OSAHS group were significantly higher than those in non-OSAHS group (P＜0.05).Logistic regression analysis showed that,IMT was independently associated with TNF-α and hs-CRP.Conclusion Patients of T2DM with OSAHS have poor blood glucose control and higher incidence of atherosclerosis.High levels of TNF-α and hs-CRP may be involved in the formation of atherosclerosis and plaque occurrence and development.

Prognosis analyses of 133 nasopharyneal carcinona from northwest China treated by intensitymodulated radiotherapy / 中华放射肿瘤学杂志

ObjectiveTo evaluate the long term outcomes, toxicities and prognostic factors of the patients in Northwest China with nasopharyngealcarcinoma (NPC)treated by intensity-modulated radiotherapy (IMRT). MethodsFrom January 2006 to December 2009, 133 NPC Patients were treated by IMRT in Xijing Hospital, the Fourth Military Medical University. There were 22 treated by radiotherapy alone, 111 treated by platinum-based current chemo-radiothreapy. The prescription dose to the gross tumor volume was 66 - 76. 6 Gy/30 - 33 fractions, positive lymph nodes was 66. 0 - 72. 4 Gy/30 - 33 fractions.The higher and lower risk clinical target volume were irradiated with 56. 0 - 63. 5 Gy/28 - 33 fractions and 50. 4 -53. 2 Gy/28 fractions respectively. ResultsThe follow-up rate was 97. 7％. Follow-up time more than 2years,3years were 37cases ,44cases. The l-,2-and 3-year overall survival (OS) were 93. 8％, 88. 3％and 83.2％ ; local control rate were 99. 2％ ,95.4％ and 95.4％ ; regional control rate ( RC ) were 99. 2％,96. 8％ and 96.8％ ; and distant metastasis-free rate (DMFR) were 82. 8％, 79. 8％ and 79. 8％ ; the disease-free survival (DFS) were 84. 3％ ,76. 7％ and 76. 7％, respectively. Multivariate analyses revealed that N stage, age and anemia before radiotherapy were independent predietors for OS (x2 =5.56,9. 10,4.89,P=0. 018,0.003,0.027), and N stage was also independent predictors for DFS (x2 =8.98,P=0.003).Thegrade 3acutetoxicitiesweremueositis(34.7％),xerostomia(20. 1％ ), skin reaction ( 1.4 ％ ) and leucocytopenia ( 1. 4 ％ ). No grade4 acute and late toxieities were detected. Conclusions IMRT with or without chemotherapy achieved good long term survival in nasopharyngeal carcinoma treated by intensity-modulated radiotherapy, especially in LC and RC. Distant metastasis becomes the main treatment failure.N stage, age, and anemia before radiotherapy were the main prognostic factors in nasopharyngeal cancer patients.
