Objective:To investigate the thyroid volume of adults in Lanzhou City, and analyze its influencing factors.Methods:In June 2016, according to the principle of multi-stage stratified cluster sampling, Han residents aged 18 and above in Chengguan, Xigu and Qilihe districts of Lanzhou City who had lived there for more than 5 years were selected as research subjects, and a portable B-ultrasound machine was used for thyroid examination. Morning urine samples of the subjects were collected to test urinary iodine; fasting venous blood samples of the subjects were collected to test serum thyroid stimulating hormone (TSH), thyroid peroxidase antibody (TPOAb), anti-thyroglobulin antibody (TgAb), blood lipids [triglycerides (TG), total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL)] and blood uric acid (Ua) levels. At the same time, body indexes systolic blood pressure (SP), diastolic blood pressure (DP), waist circumference, height and weight were measured, and the body mass index (BMI) was calculated. Multiple linear regression was used to analyze the influencing factors of thyroid volume.Results:A total of 1 009 subjects were included, aged (43.50 ± 15.16) years, and the thyroid volume was (8.74 ± 3.39) ml. Among them, 534 males had a thyroid volume of (9.46 ± 3.43) ml; 475 females had a thyroid volume of (7.93 ± 3.15) ml, the thyroid volume of males was larger than that of females ( t = 7.36, P < 0.01). Thyroid volume was positively correlated with age, height, weight, BMI, SP, waist circumference, LDL, Ua and TgAb ( r = 0.07, 0.23, 0.33, 0.27, 0.10, 0.27, 0.10, 0.08, 0.07, P < 0.05), and it was negatively correlated with thyroid nodules, TPOAb, TSH and urinary iodine ( r = - 0.16, - 0.07, - 0.10, - 0.08, P < 0.05). After multiple linear regression analysis, TSH, TPOAb, TgAb and thyroid nodules were included in the regression equation, and the standardized B values were - 0.135, - 0.065, 0.123 and - 0.197, respectively. Conclusions:The thyroid volume of males is larger than that of females in Lanzhou City. TSH, TPOAb, TgAb and thyroid nodules are influencing factors of thyroid volume.

Primary tracheal adenoid cystic carcinoma (TACC) is exceedingly rare. Surgical resection is the main treatment for TACC. Whether the operation is radical or not is a key prognostic factor. Postoperative radiotherapy may be suitable to improve the local control rate and long-term survival for patients with positive surgical margin. For unresectable, recurrent and metastatic TACC patients, definitive radiotherapy, chemotherapy and molecular targeted therapies have yielded certain clinical efficacy. The aim of this review is to summarize the research progress on multimodality treatment for TACC.

Heavy ion radiation has significant radiological and biological advantages over conventional radiation. While directly killing tumor cells, heavy ion beam can reduce immune escape and promote the initiation and activation of effector T cells by inducing immunogenic death of tumor cells, regulating tumor phenotype, enhancing antigen formulation, and changing tumor microenvironment to regulate the immune response. This article will review the immunomodulatory effect of heavy ion beam and the molecular mechanisms associated with immune checkpoint inhibitor therapy.

Along with the development of modern medical modality and health awareness, the maintenance of favorable quality of life ( QoL) has become one of the most important goals for cancer survivors. Non-small-cell lung cancer ( NSCLC) survivors may suffer from substantial impairment on the overall QoL due to surgical treatment, radiotherapy and chemotherapy, etc. Evaluating the effect of NSCLC treatment upon the QoL of NSCLC patients contributes to understanding and enhancing the QoL through relevant interventions, improving life-cycle surveillance and subsequently obtaining the optimal therapeutic option. In this paper, recent researches on the QoL of NSCLC patients were summarized and reviewed.

Objective@#The aim of this retrospective study was to evaluate the prognostic significance of pretreatment Neutrophil-to-Lymphocyte Ratio(NLR) in locally advanced non-small cell lung cancer(NSCLC) patients treated with thoracic radiotherapy.@*Methods@#We retrospectively analyze 420 patients who received thoracic radiotherapy alone, sequential chemoraiotherapy or concurrent chemoradiotherapy for locally advanced stage NSCLC from January 2007 to December 2010 of our hospital. The patients were divided into two groups (high NLR group and low NLR group) with appropriate cutoff point using the receiver operating characteristic (ROC) curve method. The survival curve was established by Kaplan-Meier method. The Log-rank test was used to compare the survival of the two NLR groups and the multivariate analysis was carried out by Cox regression model.@*Results@#Among the 420 patients, 99 received radiotherapy alone, 139 received sequential chemoradiotherapy and 182 received concurrent chemoradiotherapy. 345 patients died and 75 were still alive. The median follow-up time was 5.2 years and the median overall survival was 22 months. The cut-off value of pretreatment NLR was 2.1. The 5-year PFS and OS rates in high NLR group and low NLR group were 10.6% vs 15.7% (P=0.033) and 15.5% vs 22.7% (P=0.012). Multivariate analysis confirmed that pretreatment NLR (hazard ratio 1.06, P=0.041) was independent prognostic factor of OS.@*Conclusions@#Our study revealed that the pretreatment NLR is the independent prognostic factor of OS in patients with locally advanced stage NSCLC treated with thoracic radiotherapy. However, NLR is still greatly influenced by patient′s condition and treatment which needs further research.

Objective To evaluate the toxicity and efficacy of carbon ion radiotherapy for cutaneous malignant melanoma. Methods Form December 2006 to May 2009, 13 patients with superficial malignant melanoma were treated with carbon ion radiotherapy in the Institute of Modern Physics, Chinese Academy of Sciences. The total dose was 60 -66 GyE in 6 -12 fractions within 6 -12 days. The disease was Stage Ⅱ_a in 2, Ⅱ_b in 3, Ⅱ_c in 5, and Ⅲ_c in 3 patients. The toxicities were assessed according to the Radiation Therapy Oncology Group (RTOG) criteria, and the efficacy was evaluated with WHO criteria. Results The median follow-up time was 13.5 months (range, 1 -25 months) and the follow-up rate was 100%. Of the 13 patients, 10(77%) achieved complete remission (CR), and 3(23%) partial remission (PR). The overall response rate (RR) was 100%, and the median survival time was 21.3 months (95% CI, 18. 1 -24.5 months). The grade 0, 1,2 and 3 skin reaction occurred in 3, 6, 2 and 2 patients, respectively. The hematologic toxicities were mild. Conclusions Carbon ion radiotherapy is a safe and effective treatment for cutaneous malignant melanoma.
