With an increasing prevalence all over the world,diabetes mellitus is considered as a potential cause of liver cancer in patients with non-viral hepatitis.Whether diabetes mellitus is the cause of liver cancer and related pathogenesis remain unknown.The article reviews recent large-sample cohort studies and confirms that diabetes mellitus increases the incidence rate of liver cancer and affects its prognosis.This article also investigates the association of hepatitis C,obesity,and nonalcoholic fatty liver disease with diabetes mellitus and liver cancer and finds that insulin resistance and activation of chronic inflammatory factors may be involved in the generation and proliferation of cancer cells.This article elaborates on the influence of anti-insulin resistance drugs on the development and progression of liver cancer and points out that diabetes mellitus may be the cause of liver cancer.Effective control of insulin resistance can help to reduce the development and progression of diabetes-associated liver cancer.

Objective To investigate the effects of siRNA silencing of inhibitor of apoptosis protein gene on the proliferation of airway smooth muscle in bronchial asthma mice .Methods Tweenty female BALB/c mice were randomly divided into experimen‐tal group and control group .Mice in the experimental group were constructed asthma models .The trachea and bronchi were collect‐ed for cell culture .Respectively ,the cultured airway smooth muscle cells in the experimental group and the control group were grouped:PBS control group (added to PBS solution) ,missense chain control group (transfected with missense chain) and siRNA transfection group (transfected with siRNA Survivin) .The expressions of Survivin mRNA ,Survivin protein and caspase‐9 protein in airway smooth muscle cells were detected .The levels of IL‐6 and CCL5 in cell supernatant were detected .Results RT‐PCR re‐sults showed that ,the relative expression levels of Survivin RNA of airway smooth muscle cells in the siRNA transfection group of the experimental group were lower than the PBS control group and missense chain group ,the differences were statistically signifi‐cant (P<0 .05) .Western blot results showed that ,the expressions of Survivin proteins in the siRNA transfection group of the ex‐perimental group were lower than the PBS control group and missense chain control group ,while the caspase‐9 protein were higher , In the experimental group ,the synthesis and secretion levels of IL‐6 and CCL5 of airway smooth muscle cells in the siRNA transfec‐tion group were lower than the PBS control group and missense chain control group ,the cell proliferations at 2-4 d in the siRNA transfection group were lower than the PBS control group and missense chain control group ,the proportion of G0/G1 phase in the siRNA transfection group were higher than the PBS control group and missense chain control group ,but the proportion of S/G2 phase were lower than the PBS control group and missense chain control group ,cells apoptosis rates of the siRNA transfection group were lower than the PBS control group and missense chain control group ,the differences were statistically significant (P<0 .05) .Conclusion siRNA specific silencing Survivin gene could accelerate the airway smooth muscle cell apoptosis ,and inhibit cell abnormal proliferation and secretion .

Objective:To study and analyze the quality assurance(QA) and quality control(QC) in chest radiography based on X-ray digital radiography (DR).Methods:600 cases ( 320 male cases, 280 female cases, age range from 2 to 68 years old, with an average 48.2 years old) chest radiography based on DR were random sampling from database during the period from Oct., 2015 to Dec., 2015. In accordance with chest imaging criteria, these images were graded, and calculated the share rate. After analyzing the causes that produced the bad images, a number of measures were provided to improve the quality of image.Results:The patients can be examined in short time, and there are a large number of information with high resolution and rich layers. The qualified rate was 100% (Grade A with 525, accounting for 87.5%,Grade B with 63, accounting for 10.5%; Grade C with 12 , accounting for 2%), and the rate of waste film was zero.Conclusion: DR produced by computer digital image processing technology combined with X-ray radiation technology has powerful post-processing function. This function can combine a series of quality control measures to improve image quality as reducing radiation dosage, and finally, to realize the target of QA and QC.

Objective:To investigate the significance of 3D printing technology in the treatment of skull base tumor.Methods: A 45-year-old male patient who felt headache and discomfort had progressive loss of vision to blindness in the left eye. Using MR plain scan found that there was a skull base tumor, so the patient was examined by brain CTA and 3.0T MR to obtain medical digital imaging of CT and MR and DICOM data which were input into computer for establishing three-dimensional model, and then printed it.Results: 3D reconstruction model can clearly display the anatomical structure of skull base tumor, three-dimensional space and peripheral blood around skull base tumor. Under the guidance of this new technology, the tumor was completely removed and the surrounding normal brain tissue was preserved as much as possible. The whole operation time was greatly reduced at the same time.Conclusion: The treatment of 3D printing technology is applied in skull base tumors can clearly display the anatomical structure, distinguish adjacent vessels around tumor; when it avoids missing tumor, also can more effectively assist preoperative planning, enhance the security for complex skull base surgery, accelerate the operation speed, improve operation accuracy; it has great application prospect in the precise treatment of neurosurgery.

Objective:To discuss the value of low dose scanning technique of 16-slice spiral CT for the diagnosis of pulmonary diseases.Methods: A retrospective analysis was adopted to analyze 43 image documents were scanned by 16-slice spiral CT and to evaluate their qualities.Results:All of patients were examined in accordance with the requirements and all of image qualities were more than good. Although their background noise were increased, the image quality did not affect the display of anatomical structure. Therefore, it can satisfy the requirements for the diagnosis of pulmonary diseases.Conclusion:The pulmonary multi-slice spiral CT based on low-dose scanning technology can improve the detection rate of lesions, reduce radiation dose for patients, prolong the service life of the tube and reduce the maintenance cost, therefore it is worthy for further promotion.

Acute kidney injury is a common complication in patients with cirrhosis.It is characterized by a sudden drop in glomerular filtra-tion rate,retention of metabolic waste products,water-electrolyte imbalance,and acid-base disturbance.It markedly increases mortality in cirrhotic patients.Therefore,early diagnosis and treatment of acute kidney injury are essential to reduce mortality and improve prognosis. The development of the diagnostic criteria for acute kidney injury,the clinical application of new biomarkers of renal function such as cystatin C,kidney injury molecule-1 ,and neutrophil gelatinase-associated lipocalin,and the management of acute kidney injury in cirrhotic pa-tients are reviewed.Although creatinine test and monitoring of urinary output have their disadvantages,they remain the main diagnostic crite-ria for acute kidney injury.Development of new biomarkers for clinical use and elucidation of the underlying mechanisms of acute kidney in-jury have become a hotspot of basic and clinical research.

In recent years,gut microecology has attracted increasing attention because of its close relationship with the development and pro-gression of various liver diseases and associated complications.The impairment of liver function can disturb gut microecology,whereas the imbalance in gut microecology in turn promotes the aggravation of liver diseases.This paper reviews the relationship between gut microecolo-gy and various liver diseases,and discusses the role of modulating gut microecology in the treatment of liver diseases.A new idea is provided for the prevention and treatment of liver diseases based on the modulation of gut microecology.
