ABSTRACT

Objective:To explore the significance of the clinical target volume (CTV) dose optimization in the upper and middle neck in protecting the laryngopharynx, anterior and posterior rings during intensity-modulated radiotherapy (IMRT) and multimodal imaging system for nasopharyngeal carcinoma.Methods:Clinical data of 298 nasopharyngeal carcinoma patients admitted to Jiangsu Cancer Hospital from 2016 to 2018 were retrospectively analyzed. According to the following five strategies of CTV dose optimization in the upper and middle neck: group A, complete optimization of bilateral cervical lymph nodes (CLNs), that is, the CTV doses of bilateral CLNs were 50.4 Gy; group B, complete optimization of unilateral CLNs, that is, the CTV dose of unilateral CLNs was 50.4 Gy and the contralateral CLNs was 60 Gy; group C, incomplete optimization of bilateral CLNs, that is, the CTV doses of bilateral CLNs were 50.4 Gy, while the suspicious positive CLNs were selectively boosted to 60 Gy; group D, incomplete optimization of unilateral CLNs, that is, the CTV dose of unilateral CLNs was 50.4 Gy and the suspicious positive CLNs were selectively boosted to 60 Gy, and the CTV dose of contralateral side was 60 Gy; group E: no optimization, that is, the CTV doses of bilateral CLNs were 60 Gy.Results:Among 298 patients, 215 patients received dose optimization and 83 cases did not receive dose optimization. In the dose optimization schemes, 114 cases were assigned in group A, 36 cases in group B, 60 cases in group C and 5 cases in group D. The median (range) follow-up time was 28.5(6.0-46.3) months. The overall survival rate was 95.6%, the progression-free survival rate was 84.2% and the locoregional control rate of CLNs was 98.0%. Local relapse of CLNs occurred in six patients, including 1 case of retropharyngeal lymph node, 4 cases of Ⅱ area and 1 case of Ⅳ area. The P values of average dose of laryngopharynx in group A, group B, group C and group D compared with that in group E were<0.001, 0.016, 0.001 and 0.572, respectively. The P values of the average dose of the anterior ring in group A, group B, group C and group D compared with that in group E were<0.001, 0.011, <0.001 and 0.805, respectively. The P values of the average dose of the posterior ring in group A, group B, group C and group D compared with that in group E were<0.001, 0.004, <0.001 and 0.252, respectively.Conclusions:Combined with the metastatic rules of CLNs and multimodal imaging system, it is safe to optimize the CTV dose of the upper and middle neck during IMRT in nasopharyngeal carcinoma patients, which can significantly reduce the doses of laryngopharynx, anterior and posterior rings, thereby providing evidence for reducing the CTV dose in the upper and middle neck.

ABSTRACT

Objective:To investigate the clinical characteristics of patients infected with Brucella Melitensis ( B. Melitensis) type 1 and type 3 in Hulunbuir, Inner Mongolia Autonomous Region. Methods:A retrospective analysis method was used to collect clinical medical records of patients with brucellosis admitted to Hulunbuir People's Hospital from June 2013 to August 2017, and 71 patients with brucellosis positive in blood culture and identified by polymerase chain reaction (PCR) and AMOS-PCR were selected as the study subjects. According to the identification results, they were divided into B. Melitensis type 1 and type 3 groups. General information, epidemiological characteristics, clinical characteristics, laboratory examinations, complications and efficacy of the two groups were compared. Results:Among 71 patients with brucellosis, 22 cases were B. Melitensis type 1, including 16 males and 6 females, aged (39.91 ± 16.04) years old; 49 cases were B. Melitensis type 3, including 34 males and 15 females, aged (40.67 ± 18.72) years old. There were no significant differences in gender composition and age between the two groups (χ 2 = 0.081, t = 0.166, P > 0.05). There were 10 cases(45.5%) of B. Melitensis type 1 patients living in agricultural areas, 10 cases (45.5%) in pastoral areas, and 2 cases (9.1%) in cities; there were 40 cases (81.6%) of B. Melitensis type 3 patients living in agricultural areas, 7 cases (14.3%) in pastoral areas and 2 cases (4.1%) in cities, and the difference between regions was statistically significant (χ 2 = 9.276, P < 0.05). Testicular swelling and pain symptoms [22.7% (5/22), 6.1% (3/49)] in B. Melitensis type 1 and type 3 patients were compared, the difference was statistically significant (χ 2 = 4.187, P < 0.05); other clinical features were compared, the differences were not statistically significant ( P > 0.05). There were no significant differences in white blood cell count (WBC) and platelet count (PLT) decreased, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) increased between the two groups ( P > 0.05). The number of complications in B. Melitensis type 1 and type 3 patients were 12 cases (54.5%) and 14 cases (28.6%), respectively, and the difference between the two groups was statistically significant (χ 2 = 4.413, P < 0.05). Ten cases (45.5%) of B. Melitensis type 1 patients were cured, 12 cases (54.5%) were improved, 34 cases (69.4%) of B. Melitensis type 3 patients were cured, 15 cases (30.6%) were improved, and there were no invalid or relapsed patients in both groups, the difference in curative effect between the two groups was statistically significant (χ 2 = 3.690, P < 0.05). Conclusions:In Hulunbuir, Inner Mongolia Autonomous Region, there are differences in the living areas of B. Melitensis type 1 and type 3 patients. The B. Melitensis type 1 patients are prone to testicular swelling and pain and brucellosis complications.

ABSTRACT

Objective:To conduct a meta-analysis of clinical data to investigate the relationship between incretins and fracture in order to provide individualized hypoglycemic agents for type 2 diabetic patients with osteoporosis.Methods:PubMed, Embase, Web of Science, and Cochrane databases were searched up to January 1, 2018 for randomized controlled trials(RCTs)and the relationship between incretins and fracture was explored by meta-analysis.Results:The meta-analysis showed that the use of incretin was not associated with fracture risk compared with placebo or other positive hypoglycemic agents( OR 0.972, 95% CI 0.876-1.079). But in the subgroup analysis, 100 mg/d sitagliptin( OR 0.495, 95% CI 0.304-0.806)or 1.8 mg/d liraglutide( OR 0.621, 95% CI 0.413-0.933)reduced fracture risk. Conclusions:Meta-analysis shows no increase in the incidence of fracture events after the use of incretin. 100 mg/d sitagliptin or 1.8 mg/d liraglutide may exert protective effects on bone metabolism. However, the included data are from the reports of fracture adverse reactions in RCT studies, and large-scale clinical studies are needed to confirm these findings.

ABSTRACT

Neuroinflammation plays an important role in the pathogenesis of Alzheimer's disease(AD), which requires the involvement of microglia.Missense mutations in the triggering receptor expressed on myeloid cells 2(TREM2)gene are a risk factor for AD, and the gene encodes single-channel transmembrane receptors on the surface of microglia and regulates downstream signaling pathways by binding to TYRO protein tyrosine kinase-binding protein to form a complex.The TREM2 receptor participates in many functions of microglia, such as proliferation, migration, and phagocytosis.Microglia functions can be impaired when the TREM2 gene or its protein expression is abnormal.In addition, TREM2 can bind to β-amyloid oligomers and is also associated with Tau proteins.All of these findings suggest that TREM2 is involved in the pathogenesis of AD, but its specific role remains a matter of dispute.

ABSTRACT

Objective:To analyze the epidemiological characteristics, clinical features of brucellosis patients with abnormal blood routine, and to improve the awareness of brucellosis among clinicians.Methods:A total of 1 036 patients with brucellosis admitted to the Department of Brucellosis, Hulunbuir People's Hospital from January 2011 to December 2017 were selected, including 274 patients with abnormal blood routine (case group), and 762 patients with normal blood routine(conrtol group). Epidemiological characteristics, clinical features and laboratory tests were analyzed retrospectively.Results:In 274 patients of case group, there were 128 males and 146 females, and the age was (36.3 ± 18.7) years old. In 762 patients of conrtol group, there were 381 males and 381 females, and the age was (35.4 ± 20.4) years old, and there were no significant differences in sex ratio and age between the two groups ( P > 0.05). The main route of infection in the two groups was to raise livestock such as sheep and cattle, 254 cases (92.7%) and 724 cases (95.0%), respectively. The proportions of patients with dizziness symptoms were 31.0% (85/274) and 17.7% (135/762) in the two groups, and the proportions of patients with rash were 14.2% (39/274) and 3.0% (23/762), and the differences were statistically significant between the two groups (χ 2 = 21.331, 45.054, P < 0.05). The symptoms of fever, sweating and fatigue were common in both groups, and the splenomegaly was the most common sign. However, there were no significant differences in the proportion of abnormal characteristics between the two groups ( P > 0.05). Among the 274 patients in case group, 48 had leucopenia, 160 had anemia, and 148 had thrombocytopenia; and 17 had both leucopenia and anemia, 23 had both leucopenia and thrombocytopenia, and 16 had both anemia and thrombocytopenia, and 13 had leucopenia, anemia, and thrombocytopenia at the same time. Conclusions:In the brucellosis epidemic area, when the patient has symptoms such as fever, fatigue, sweating, leucopenia, anemia, and thrombocytopenia, and excluding abnormal blood routine caused by other reasons, clinicians should consider the possibility of Brucella infection.

ABSTRACT

Objective@#To analyze the characteristics of the second primary tumor affecting the survival of patients with lymphoma, and to explore the risk factors of death from the second primary tumor.@*Methods@#The medical records and related death information of 1 173 lymphoma patients who had already died with known causes were collected. The basic causes of death and the characteristics of patients who died of the second primary tumor were analyzed. Cox regression model was used to analyze the risk factors of lymphoma patients who died of the second primary tumor.@*Results@#Among the 1 173 patients who had died, 94 (8.0%) died of the second primary tumor, 935 (79.7%) died of the primary lymphoma and 144 (12.3%) died of other diseases. The second primary tumor accounted for 17.5% (38/217) of all causes of death in patients with the survival period of more than 5 years, and the second primary tumor accounted for 28.3% (17/60) of all causes of death in patients with the survival period of more than 10 years. Among 94 cases who died of second primary tumors, 31 died of lung cancer, 15 died of gastric cancer, 13 died of liver cancer, 9 died of pancreatic cancer, 6 died of colorectal cancer, 6 died of second primary lymphoma and 14 died of other types of tumors. Univariate Cox regression analysis showed that age, first-line treatment effect, and chest or mediastinal radiotherapy were associated with the death from second primary tumors for lymphoma patients (all P<0.05). Multivariate Cox regression analysis showed that the effect of first-line treatment (P=0.030) and the chest or mediastinal radiotherapy (P=0.039) were independent factors for the death of lymphoma patients from the second primary tumor.@*Conclusions@#The second primary tumor is an important factor affecting the survival of lymphoma patients, and the risk of death from second primary tumors increases significantly over time. The effect of first-line treatment and radiotherapy in the chest or mediastinum are independent factors for the death of lymphoma patients from the second primary tumor.

ABSTRACT

BACKGROUND@#Thymoma is the most common malignant tumor in anterior mediastinum, and its specific pathogenesis is still unclear. This limits the study of targeted drugs for thymoma. The aim of the study is to investigate the genes and signal pathways of thymoma, and provide help for the research of thymic tumor pathogenesis using the technology of second-generation genechip to analyze thymoma.@*METHODS@#From January 2015 to December 2017, we analyzed 31 cases of thymoma by CapitaBio mRNA expression profile genechip technology, and then confirmed the genes by reverse transcription-polymerase chain reaction (RT-PCR).@*RESULTS@#We found some genes with different expression levels between thymoma and surrounding thymus tissue. Among them, six driving genes (FANCI, CAPD3, NCAPG, OXCT1, EPHA1 and MCM2) were significantly abnormal in thymoma. Some specific genes affected by copy-number variation were detected: E2F2, EphA1, CCL25 and MCM2 were significantly up-regulated, while IL-6, CD36, FABP4, SH2D1A and MYOC genes were significantly down-regulated. KEGG database analysis showed that the expression of 10 signaling pathway genes was generally up-regulated or down-regulated, such as systemic lupus erythematosus, viral oncogenes, primary immunodeficiency, cell cycle genes and p53 signaling pathway, which may be related to occurrence of thymoma.@*CONCLUSIONS@#We found a variety of genes abnormally expressed in thymoma, which will provide reference for the study of pathogenesis and biomarkers of thymoma in the future.

ABSTRACT

Background A healthy diet in a college student life is critical to ensure their normal growth, study anddevelopment.Aim In order to accurately assess the dietary pattern of college students and guide it, our study aims to evaluatethe validity of instant photography as an alternative dietary assessment method in college students.Methods Nine participants were enrolled and given a presentation on dietary assessment methods, includingweighing, 24-hour recall, and instant photography. The participants took pictures of their foods from three anglesbefore and after eating for constant seven days, foods weighing was completed by others. Then, the participantsrecalled the foods’ weights after 24 hours. Two trained observers estimated food weight from the digital images(n = 285) gathered at the end of the study with the aid of Chinese food atlas reference.Results Instant photograph showed significant correlation with weighing method on food weights of grains,tubers, vegetables, fruits, meat and eggs (all P ≤ 0.01). 24-hour method had similar correlation with weighingmethod on food weights except fruits. Compared with 24-hour recall, instant photograph displayedunderestimation on weights of grains, tubers, vegetables, and meat. However, instant photograph had moreaccurate estimations on weights of fruits and egg. Furthermore, compared with nutrients data from weighingmethod, both instant photography and 24-hour recall methods showed promising estimations on the amounts ofenergy, protein, fat, carbohydrate, vitamin A, vitamin C, vitamin E, calcium, iron and zinc (all P < 0.001). Comparedwith 24-hour recall, instant photograph displayed underestimation on the amounts of energy, protein, fat,carbohydrate, vitamin A, vitamin C, vitamin E, zinc. However, instant photograph had a more accurate estimationon calcium.

ABSTRACT

Objective@#To observe the safety and efficacy of fecal microbiota transplantation (FMT) in treatment of Parkinson′s disease (PD) with constipation.@*Methods@#From September 2017 to April 2019, 22 PD patients with serious constipation in the Department of Neurology, the Affiliated Huaian No. 1 People′s Hospital of Nanjing Medical University were treated with FMT and followed up for 12 weeks. Spontaneous bowel movement (SBM) per week and scores of Wexner Constipation Scale (Wexner), Constipation Quality of Life Scale (PAC-QOL) and Parkinson′s Disease Quality of Life Questionnaire (PDQ-39) were recorded before and after transplantation.@*Results@#Compared with the number of independent defecation and scores before treatment, the number of independent defecation per week (4.63±2.25, 5.38±1.23, 5.75±1.29, 5.54±1.30 vs 1.57±0.74), Wexner score (7.92±2.61, 5.67±1.78, 5.08±1.83, 4.92±1.78 vs 16.67±4.31), PAC-QOL score (62.3±3.2, 58.8±2.8, 57.1±3.9, 59.6±4.4 vs 110.3±14.7) and PDQ-39 score (44.8±14.8, 37.8±12.8, 32.8±12.3, 31.9±9.2 vs 58.7±16.7) were significantly improved by FMT treatment at two, four, eight and 12 weeks (P<0.01). After 12-week treatment, the effective rate was 100% (22/22), and the clinical cure rate was 86% (19/22). No serious adverse reactions occurred during treatment.@*Conclusion@#FMT is effective and safe in treating PD with constipation.

ABSTRACT

Objective@#To analyze the disease burden of pancreatic cancer in China in 1990 and 2017.@*Methods@#Province-specific data in China from the Global Burden of Disease Study (GBD) 2017 were used to describe the change of death status, disease burden of pancreatic cancer in Chinese population by specific province and age groups, including incidence, mortality, disability-adjusted life years (DALY), years of life lost (YLL) due to premature mortality and years lived with disability (YLD) in 1990 and 2017. Meanwhile the incidence, mortality, DALY rate, YLL rate, YLD rate were standardized by the GBD global standard population in 2017.@*Results@#In 2017, the new cases of pancreatic cancer, incidence and age-standardized incidence accounted for 83.6 thousand, 5.92/100 000 and 4.37/100 000 in China, with an increase of 230.94%, 180.45% and 49.88% compared with 1990, respectively. The total number of deaths, mortality and age-standardized mortality appeared as 85.1 thousand, 6.02/100 000, 4.48/100 000, with an increase of 236.08%, 184.80% and 47.51% respectively. The incidence and mortality of pancreatic cancer increased with age and accelerated from the age of 55 to 59 both in 1990 and 2017. The highest incidence and mortality showed in 85-89 years old in 2017 and in 90-94 years old in 1990. The standardized DALY rate of pancreatic cancer increased from 71.00/100 000 in 1990 to 94.32/100 000 in 2017, increased by 32.84%. The standardized YLL rate increased from 70.39/100 000 to 93.42/100 000, increased by 32.72%. The standardized YLD rate increased from 0.62/100 000 to 0.90/100 000, increased by 45.80%. In terms of age distribution, DALY rate, YLL rate and YLD rate of pancreatic cancer basically showed an increasing trend with age in 1990 and 2017. In 2017, Jiangsu (7.61/100 000), Shanghai (7.52/100 000) and Liaoning (6.84/100 000) ranked the top three provinces in terms of standardized mortality. Compared with 1990, Henan (104.28%), Sichuan (94.02%) and Hebei (90.39%) saw the fastest increase in standardized mortality.@*Conclusions@#The incidence, mortality and disease burden of pancreatic cancer in China increased significantly from 1990 to 2017. Prevention and control measures should be strengthened to reduce the disease burden of pancreatic cancer.

ABSTRACT

Objective@#To investigate the high-risk factors for parotid lymph node (PLN) metastasis from nasopharyngeal carcinoma (NPC) and evaluate the feasibility of local intensity-modulated radiotherapy (IMRT) in patients with high-risk NPC.@*Methods@#Clinical data of 440 NPC patients admitted to Department of Radiotherapy of Jiangsu Cancer Hospital from May, 2011 to March, 2017 were collected. The imaging features, treatment strategies and clinical prognosis of PLN metastasis were retrospectively analyzed. The whole group adopts the technique of intensity modulated radiotherapy. Total parotid or partial parotid irradiation, selective PLN irradiation, X-Ray and/or electronic line supplementation, dose 45-60 Gy. The χ2 test or Fisher′s accurate probability method test and single factor analysis, Logistic regression model multi-factor analysis. Kaplan-Meier survival analysis, log-rank test differences.@*Results@#PLN was observed in the parotid of 230 cases. At the end of follow-up, 11 patients (2.5%, 11/440) were diagnosed with PLN metastases. Among 11 cases, 9 patients (81.8%) had PLN size ≥5 mm. Multivariate analysis demonstrated that extracapsular spread of level Ⅱ was an independent risk factor for PLN metastasis. The patients with PLN size ≥5 mm or extracapsular spread of level Ⅱ were assigned into the high-risk PLN metastasis group. The patients in the high-risk group were further divided into the radiotherapy and non-radiotherapy subgroups. Survival analysis demonstrated that for 230 patients with PLN metastasis, the local recurrence-free survival (LRFS) significantly differed, whereas the overall survival (OS), disease metastasis-free survival (DMFS) and progression-free survival (PFS) did not considerably differ between the radiotherapy and non-radiotherapy subgroups in the high-risk PLN metastasis patients.@*Conclusions@#The PLN metastasis rate of NPC is low. Extracapsular spread of level Ⅱ is an independent risk factor. Radiotherapy of the parotid region is considered for patients with PLN size≥5 mm or those with PLN size<5 mm complicated with extracapsular spread of level Ⅱ.
