Objective To investigate the relationship between cardiac Tei index and plasma amino terminal brain natriuretic peptide precursor (NT- proBNP), glycosylated hemoglobin (HbA1c) in type 2 diabetes mellitus and its value in predicting the occurrence of major adverse cardiovascular events (MACE). Methods The clinical data of 160 patients with type 2 diabetes mellitus from March 2015 to October 2017 were retrospectively analyzed. The patients were divided into MACE group (45 cases) and non-MACE group (115 cases). The clinical indexes were compared between 2 groups, and the relationship between cardiac Tei index and NT-proBNP, HbA1c was analyzed. Logistic regression analysis was used to analyze the risk factors of MACE in patients with type 2 diabetes mellitus. Results The systolic blood pressure and diastolic blood pressure in MACE group were significantly lower than those in non-MACE group: (109.10 ± 14.53) mmHg (1 mmHg = 0.133 kPa) vs. (120.76 ± 18.74) mmHg and (64.29 ± 9.82) mmHg vs. (73.58 ± 12.11) mmHg, the heart rate, Killip grade > Ⅱ rate, cardiac Tei index and NT- proBNP were significantly higher than those in non- MACE group: (77.56 ± 13.36) times/min vs. (71.68 ± 11.39) times/min, 28.89% (13/45) vs. 2.61% (3/115), 0.63 ± 0.12 vs. 0.52 ± 0.08 and (1193.20 ± 145.69) μg/L vs. (823.87 ± 89.22) μg/L, and there were statistical difference (P<0.01). Pearson regression analysis result showed that cardiac Tei index was positively correlated with NT- proBNP and HbA1c (r = 0.817 and 0.793, P < 0.05), and there was positive correlation between NT-proBNP and HbA1c (r = 0.649, P < 0.05). Logistic regression analysis result showed that cardiac Tei index, NT-proBNP and HbA1c were the independent risk factors of MACE in patients with type 2 diabetes mellitus (OR = 1.015, 1.041 and 1.027; 95% CI 1.005 to 0.213, 1.012 to 7.036 and 1.002 to 4.222; P<0.01 or <0.05). Conclusions The cardiac Tei index has positive correlation with NT- proBNP and HbA1c in patients with type 2 diabetes mellitus, and both are risk factors for the occurrence of MACE. The combination of the 3 indexes can effectively predict the occurrence of MACE and assess the prognosis.

Objective:To evaluate the clinical efficacy and failure patterns of prophylactic cranial irradiation (PCI) in patients with limited-stage small cell lung cancer (LS-SCLC) on the basis of modern chemoradiotherapy and diagnostic techniques.Methods:In this retrospective study, clinical data of 201 LS-SCLC patients treated with chemotherapy (EP/CE regimens, ≥4 cycles) and intensity-modulated radiotherapy (IMRT) in Cancer Hospital of Chinese Academy of Medical Sciences from 2006 to 2014 were reviewed. All patients were primarily managed with concurrent or sequential chemoradiotherapy and achieved complete response (CR) or partial response (PR). Ninety percent of patients were revaluated for brain metastasis (BM) by MRI and 10% by CT scan. Long-term survival and failure patterns were compared between the PCI ( n=91) and non-PCI groups ( n=110). Results:The median follow-up time was 77.3 months (95% CI 73.0-81.5 months). The median overall survival (OS), 2-and 5-year OS rates were 58.5 months, 72.5% and 47.7% in the PCI group, and 34.5 months, 61.7% and 35.8% in the non-PCI group ( P=0.075). The median progression-free survival (PFS), 2-and 5-year PFS rate were 22.0 months, 48.0% and 43.4% in the PCI group, significantly higher than 13.9 months, 34.4% and 26.7% in the non-PCI group ( P=0.002). The 2- and 5-year cumulative incidence of BM were 6.6% and 12.2% in the PCI group, and 30.0% , 31.0% in the non-PCI group ( P=0.001). The median time and rate of BM as an isolated first site of relapse were 11.9 months and 4.4% in the PCI group, and 8.7 months and 25.5% in the non-PCI group ( P<0.001). Multivariate analysis showed that response after chemoradiotherapy ( P<0.001) and PCI ( P=0.033) were the independent prognostic factors for PFS. Stratified analysis demonstrated that PCI significantly improved the 5-year PFS in patients who achieved CR (72.7% vs. 48.0%, P=0.013), while it did not improve the 5-year PFS in patients who obtained PR (26.1% vs. 20.2%, P=0.213). Conclusion:In the new era of standard chemoradiotherapy and more accurate diagnostic methods for BM, PCI was associated with improved PFS and lower incidence of BM in LS-SCLC patients.

Objective To observe the objective response rate, survival and safety of radiotherapy combined with Iressa for patients with locally advanced non-small cell lung cancer ( NSCLC) unsuitable for surgery or concurrent chemoradiotherapy. Methods The patients with locally advanced NSCLC unsuitable for surgery or concurrent chemoradiotherapy were recruited and received thoracic intensity-modulated radiotherapy ( IMRT) combined with Iressa 250 mg daily. Results A total of 30 patients were enrolled between July 2014 and March 2017. Twenty-nine patients were analyzed. At 1 month after radiotherapy,the complete response (CR) was 0,partial response (PR) was 21(72%),stable disease (SD) was 6(21%), progressive disease (PD) was 2(7%),the disease control rate (CR+PR+SD) was 93%,and the objective response rate was 72%. The median follow-up time was 25 months. Fourteen ( 48%) patients died,and 15 (52%) survived. Twenty-three (79%) patients obtained PD including local progression in 18(62%) and distant metastasis in 14(48%). The median survival time (MST) was 26 months and the median PFS was 11 months. The 1-year OS and PFS were 79% and 44%,and the 2-year OS and PFS were 55% and 18%. Univariate analysis demonstrated that smoking history and disease stage were influencing factors for OS ( P=0. 035,0. 031) . Moreover, disease stage, the primary tumor diameter, the volume of GTV and PTV were influencing factors for PFS (P=0. 000,0. 016,0. 039,0. 030). Multivariable analysis revealed that disease stage and the volume of PTV were independent prognostic factors for PFS (P=0. 000,0. 012).Two patients ( 7%) developed grade 3 acute adverse events and 7 ( 24%) experienced grade 2 acute irradiation pneumonitis. Conclusions For patients with locally advanced NSCLC unsuitable for surgery or concurrent chemoradiotherapy,IMRT combined with Iressa yields high objective response rate and well tolerance. The long-term clinical efficacy remains to be validated.

Objective To evaluate the dose distribution and clinical efficacy of hippocampal-sparing prophylactic cranial irradiation ( HS-PCI ) in patients with small cell lung cancer by using helical tomotherapy. Methods Clinical data of 49 patients with small cell lung cancer receiving HS-PCI using helical tomotherapy in Cancer Hospital between 2014 and 2017 were retrospectively analyzed. All patients received brain MRI to exclude the possibility of brain metastasis within 1 month after standard surgery or radio-and chemo-therapy. The prescription dose was 95% PTV,25 Gy in 10 fractions. The adverse reactions and cognitive functions of patients were observed before,6 months and 1 year after treatment,and the dose distribution in the hippocampal gyrus,survival rate and brain metastasis rate were analyzed. Results The median follow-up time was 16 months. The average dose in the hippocampal gyrus was 7. 23 Gy and 8. 46 Gy in the reduction region,which was reduced by 71. 88% and 66. 16% compared with the prescription dose. The maximum dose in the hippocampal gyrus was 10. 66 Gy and 15. 43 Gy in the reduction region. Among 49 patients,8 died,the 1-year survival rate was 85. 1% and the 2-year survival rate was 70. 3%.Nine patients (18. 3%) had brain metastases,and one of them with extensive multiple brain metastases (n=13) presented with metastasis adjacent to the hippocampal gyrus. The main adverse reactions included mild headache, dizziness and brain edema,whereas no ≥ grade 2 adverse reactions occurred. At 6 months after treatment, the HVLT-R score was significantly decreased,and declined by 6. 78% at 12 months after treatment. The HVLT-R scores did not significantly differ in patients without brain metastasis before and 12 months after treatment ( P>0. 05 ). Conclusion Application of HS-PCI using helical tomotherapy meets the dose requirement,effectively protects the cognitive function and yields slight adverse reactions.

Objective:
To evaluate the short-term clinical efficacy and adverse events of volumetric modulated arc therapy (VMAT) in the treatment of locally advanced non-small cell lung cancer (NSCLC).
Methods:
From January to December 2016, 58 patients (47 male and 11 female) with unresectable locally advanced NSCLC received concurrent or sequential chemoradiotherapy. The radiation dose was ranged from 38 Gy to 66 Gy. The radiation dose was equal or higher than 56 Gy in 53 patients (92%). The median radiotherapy fraction was 30, 1.8 Gy to 3.0 Gy for each fraction. Twenty-eight patients (48%) received concurrent chemoradiotherapy.
Results:
The median follow-up time was 9 months. The 1-year overall survival (OS) rate was 84% and the 1-year progression-free survival (PFS) rate was 48%.Eleven patients (19%) suffered from symptomatic radiation pneumonitis and one of them died of radiation pneumonitis. Within 6 months after radiotherapy, 31 patients (53%) developed asymptomatic local pulmonary fibrosis on CT images. Seventeen patients (29%) suffered from grade Ⅱ esophagitis. Ten cases (17%) had ≥ grade Ⅲ adverse events and 9 of them presented with leucopenia.
Conclusions
VMAT yields high short-term clinical efficacy and tolerable adverse events in the treatment of locally advanced NSCLC, which does not increase the risk of pneumonitis.

Objective:
To evaluate the tolerability and short-term efficacy of chemo-radiotherapy in 125 patients with stage ⅡB-ⅣA esophageal carcinoma after radical resection.
Methods:
We retrospectively evaluated the rate of completion, toxicity and survival of patients undergoing adjuvant concurrent chemo-radiotherapy after radical resection of esophageal carcinoma from January 2004 to December 2014 in our institution. The survival rate was determined by the Kaplan-Meier method and analyzed using the log-rank test. Multivariate prognostic analysis was performed using the Cox proportional hazard model.
Results:
122 patients received more than 50 Gy dose (97.6%). A total of 52 patients received more than 5 weeks chemo-radiotherapy (41.6%), while 73 patients underwent only 1-4 weeks (58.4%). The median following up was 48.4 months. 8 patients lost follow up (6.4%). The 1-year and 3-year overall survival rate were 91.6% and 57.0%, respectively, with a median survival time of 64.4 months. The 1-year and 3-year disease free survival rate were 73.2% and 54.3%, respectively, with a median disease free survival time of 59.1 months. The most common acute complications associated with chemo-radiotherapy were myelosuppression, radiation esophagitis and radiation dermatitis, the majority of which were Grade 1-2. Of the 125 patients, there were 59 cases of recurrence, including 23 cases with local regional recurrence, 26 cases with hematogenous metastasis, and 8 cases with mixed recurrence. Univariate analysis showed that the numbers of concurrent chemotherapy was associated with the overall survival (

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% (
