Esophageal cancer related gene 4 (ECRG4) serves as a tumor suppressor gene through interacting with NF-κB and p53 pathways.Multiple studies have demonstrated that the down-regulated expression of ECRG4 occurs in a variety of cancer types,indicating a potential application of ECRG4 as a molecular diagnostic marker as well as a therapeutic target

Objective To establish an animal model of severe blast lung injury in baby rabbits,and to provide a way to study the char-acteristic and treatment of blast lung injury in minors.Methods Randomly selected sixteen 4-weeks old New Zealand white rabbits,and the blast lung injuries were made by BST-Ⅰ biological shock tube with different drive pressure (4.0 MPa and 4.5 MPa)respectively.Then compared the injury severity of the 4.0 Mpa group and the 4.5 MPa group.Selected forty-eight 4-weeks old New Zealand white rabbits and di-vided them into the control group (8 rabbits)and the blast lung injury group (40 rabbits)Rabbits in the blast lung injury group were injured with 4.5 MPa drive pressure.Observed the vital signs,physiological index,gross anatomy of the lung,pathology,and pulmonary water content at the time of injury immediately (0 hour),2 hours,4 hours,6 hours,12 hours,24 hours,48 hours and 72 hours after the injury.Results Rabbits inthe 4.0 Mpa group and the 4.5 MPa group were all alive.The overpressure of blast wave of the 4.0Mpa group was (328.16 ± 4.78)kPa,rate of severe pulmonary defense was 12.5%,and the AIS score was (3.38 ±0.52)points.In the 4.5 MPa group,the overpressure of blast wave was (395.04 ±11.74)kPa,rate of severe pulmonary defense was 87.5%,and the AIS score was (4.13 ±0.64) points.Rabbits in the control group and the blast lung injury group were all alive.The spirits of rabbits were drooping immediately after inju-ry,and it last about 0.5 hour.Then the breathing and heart rate was accelerated,pulmonary water content was increased significantly,and there were extensive hemorrhage and edema in the lung.Most of the rabbits suffered severe lung injury,and the AIS score was (3.98 ±0.55) points.Lung tissue rupture,hemorrhage,edema,and inflammatory cells infiltration were the main pathological manifestations under light microscopy. Conclusion The model of severe blast lung injury in baby rabbits could be established with BST-Ⅰbiological shock tube and drive pressure of 4.5 MPa.It is relatively simple,easily controllable and highly repeatable,which can be used as a feasible model for the study of blast lung injury.

Objective To observe the clinical effect of Sangpa Zhike decoction in the treatment of acute exacerbations of chronic bronchitis. Methods 180 patients with acute exacerbation of chronic bronchitis admitted to Autonomous Prefecture Hospital of traditional Chinese medicine(TCM)in Changji,Xinjiang,from August 2012 to August 2013 were enrolled. They were divided into Sangpa Zhike decoction treatment group and western medicine treatment control group by random number table,90 cases in each group. General treatments were given to the two groups. In the Sangpa Zhike decoction treatment group,additionally only oral Sangpa Zhike decoction was given(composition:Morus alba 10 g,loquat leaf 10 g,Houttuynia 10 g,honey aster 15 g,honey coltsfoot flower 6 g,Zhejiang Fritillaria 12 g,perilla 10 g,white mustard seed 6 g,Platycodon grandiflorum 10 g,Rhizoma Cynanchi Stauntonii 12 g,tangerine peel 6 g,Stemona 6 g). The ingredients were mixed in water and boiled to form a decoction,one dose daily,divided into two parts to be taken twice a day. In the western medicine treatment group,the infection was controlled by western medicine and the drugs to eliminate cough and phlegm,etc were used. The therapeutic course in both groups was 7 days. The therapeutic effect for treatment of TCM syndromes and the cough quantized integration score in the two groups were observed after treatment. Results The cure rate of Sangpa Zhike decoction treatment group was significantly higher than that of western medicine treatment control group〔70.00%(63/90)vs. 33.33%(30/90),P<0.01〕. Before treatment,the cough symptom quantization integral scores in the two groups had no statistically significance, but after treatment,the scores in the two groups were significantly lower than those before treatment. And the score in Sangpa Zhike decoction treatment group was decreased more significantly (1.66±1.12 vs. 4.36±2.32, P<0.01). Conclusion Sangpa Zhike Decoction has obvious curative effect in the treatment of acute attack of chronic bronchitis.

Cancer is one of the leading causes of death worldwide and the number of cancer patients is expected to continuously increase in the future. Traditional cancer therapies focus on inhibiting cancer growth while largely ignoring the contribution of the immune system in eliminating cancer cells. Recently, better understanding of immunological mechanisms pertaining to cancer progress has led to development of several immunotherapies, which revolutionized cancer treatment. Nonetheless, only a small proportion of cancer patients respond to immunotherapy and maintain a durable response. Among multiple factors contributing to the variability of immunotherapy response rates, commensal microbiota inhabiting patients have been identified as one of the most critical factors determining the success of immunotherapy. The functional diversity of microbiota differentially affects the host immune system and controls the efficacy of immunotherapy in individual cancer patients. Moreover, clinical studies have demonstrated that changing the gut microbiota composition by fecal microbiota transplantation in patients who failed a previous immunotherapy converts them to responders of the same therapy. Consequently, both academic and industrial researchers are putting extensive efforts to identify and develop specific bacteria or bacteria mixtures for cancer immunotherapy. In this review, we will summarize the immunological roles of commensal microbiota in cancer treatment and give specific examples of bacteria that show anticancer effect when administered as a monotherapy or as an adjuvant agent for immunotherapy. We will also list ongoing clinical trials testing the anticancer effect of commensal bacteria.

Objective To compare and analyze the dosimetric discrepancy of combind intracavitary/interstitial brachytherapy using three different kinds of optimization method in locally advanced cervical cancer.Methods Totally 20 cases of locally advanced cervical cancer were selected and divided into three groups according to different optimization method which include manual optimization group (MO) based on graphical optimization,inverse planning simulated annealing (IPSA 1)based on simulated annealing optimization algorithm,IPSA 2 based on IPSA 1 with limitation on maximum dose of target.The dose volume histogram parameters of the targets (V200,V150,V100,D100,D90,HI) and the OARs(D0.1 cm3,D1 cm3 and D2 cm3) were analyzed.Results For CTV,compared with MO,there was no significantly statistical difference in D100between IPSA 1 and IPSA 2(P ＞ 0.05).However,V200,V150,V100 and HI for ISPA1 were better than for ISPA2 (t =-3.422-9.910,P ＜ 0.05).In addition,V100 and D100 in ISPA1 were better than in ISPA2 (t =7.238,5.032,P ＜0.05).For OARs,D0.1 cm3,D1 cm3 and D2 cm3 in rectum,bladder,sigmoid colon of both ISPA 1 and ISPA 2 were dramatically lower than those of MO (t =2.235 5.819,P ＜ 0.05),without significantly statistical difference found between ISPA1 and ISPA2.Conclusions For combined intracavitary/interstitial brachytherapy in locally advanced cervical cancer,all treatment plans based on three different kinds of optimization methods can meet the clinical need.Moreover,inverse optimization can ensure dose coverage over target and reduce maximum dose of rectum,bladder and sigmoid colon.

BACKGROUND/AIMS: The importance of α-cell dysfunction in the pathogenesis of type 2 diabetes has re-emerged recently. However, data on whether relative glucagon excess is present in clinical settings are scarce. We aimed to investigate associations between glucagon-to-insulin ratio and various metabolic parameters. METHODS: A total of 451 patients with type 2 diabetes naïve to insulin treatment were recruited. Using glucagon-to-insulin ratio, we divided subjects into quartiles according to both fasting and postprandial glucagon-to-insulin ratios. RESULTS: The mean age of the subjects was 58 years, with a mean body mass index of 25 kg/m² The patients in the highest quartile of glucagon-to-insulin ratio had higher glycated hemoglobin (HbA1c) levels. HbA1c levels were positively correlated with both fasting and postprandial glucagon-to-insulin ratios. Subjects in the highest quartile of postprandial glucagon-to-insulin ratio were more likely to exhibit uncontrolled hyperglycemia, even after adjusting for confounding factors (odds ratio, 2.730; 95% confidence interval, 1.236 to 6.028; p for trend < 0.01). CONCLUSIONS Hyperglucagonemia relative to insulin could contribute to uncontrolled hyperglycemia in type 2 diabetes patients.

OBJECTIVETo examine the influence of China's economic reforms on population health and regional mortality rates.

METHODSLongitudinal study measuring the mortality trends and their regional variations. Using data from the three most recent national censuses, we used the model life table to adjust the mortality levels within the population for each census, and to calculate life expectancy. We then examined the variation in patterns of mortality and population health by economic status, region and gender from 1980-2000.

RESULTSLife expectancy varied with economic status, province, and gender. Results showed that, although life expectancy in China had increased overall since the early 1980s, regional differences became more pronounced. Life expectancy for populations who live in the eastern coastal provinces are greater than those in the western regions.

CONCLUSIONDifferences in life expectancy are primarily related to differences in regional economic development, which in turn exacerbate regional health inequalities. Therefore, it is necessary to improve economic development in less developed regions and to improve health policies and the public health system that address the needs of everyone.

BACKGROUND: Specific immunoglobulin E (IgE) sensitization to staphylococcal enterotoxin (SE) has been recently considered to be related to allergic disease, including asthma. Despite studies on specific IgE (sIgE) to SE and its relationship to asthma diagnosis and severity, the association of sIgE to SE with airway hyperresponsiveness (AHR) remains unclear. METHODS: We enrolled 81 asthma patients admitted to the Severance Hospital in Korea from March 1, 2013, to February 28, 2015 and retrospectively reviewed the electronic medical records of the enrolled subjects. The serum levels of sIgE to SE (A/B) of all subjects was measured using the ImmunoCAP 250 (Phadia) system with SE-sIgE positive defined as >0.10 kU/mL. RESULTS: The SE-sIgE level was not significantly correlated with asthma severity (forced expiratory volume in 1 second [FEV₁], FEV₁/forced vital capacity, sputum eosinophils, and serum eosinophils), whereas the SE-sIgE level in patients with positive AHR (mean±standard error of the mean, 0.606±0.273 kU/mL) was significantly higher than that in patients with negative AHR (0.062±0.015 kU/mL, p=0.034). In regression analysis, SE sensitization (sIgE to SE ≥0.010 kU/mL) was a significant risk factor for AHR, after adjustment for age, sex, FEV₁, and sputum eosinophils (odds ratio, 7.090; 95% confidence interval, 1.180–42.600; p=0.032). Prevalence of SE sensitization was higher in patients with allergic rhinitis and non-atopic asthma patients, as compared to patients without allergic rhinitis and atopic asthma patients, respectively, but without statistical significance. CONCLUSION: SE sensitization is significantly associated with AHR.
