The discipline of nutrition has been developing quickly in the past 30 years in China,and a number of scientific progress has been achieved.Some new discoveries have been unveiled in terms of treatment and prevention of liver carcinoma,colon cancer,and breast cancer by certain nutrients.Besides,the application of nutrition in the prevention and treatlnents of metabolic diseases such as obesity.diabetes mellitus and congenital malfcIrmation has been studied.Furthermore,academic achievements in the treatment of tumor and metabolic diseases by integrating nutritional therapies has also been made.The establishment of relevant organizations and institutes as well as the prosperous performance of nutrition education contribute to the development of discipline of nutrition in China.

Objective The purpose of this study was to examine the effects of exercise training on cardiac function and automatic nervous activity in patients with coronary artery disease(CAD) following PTCA or intracoronary stent implantation. Methods For this study, 37 CAD patients (28 men and 9 women; aged 56.23 ?11.16 years) participated in a supervised 8-week training program with 35 healthy controls(27 men and 8 women; aged 55.72 ?10.34 years). Cardiac function was assessed with indexes obtained during exercise testing using the standard Bruce protocol (submaximal gradural treadmill exercise) before and after 8 weeks training. Meanwhile, heart rate variability (HRV) was used to value the automatic nervous activity. Results After 8 weeks, the margin between maximal HR and resting HR (△HR=HR max-HR resting) was significantly broader (P

Energy metabolism refers to the metabolism of three major nutrients associated with the process of energy production and usage.The metabolism in patients with tumors manifests specifically, as a result of tumor-bearing state, host's response to tumor and anti-neoplastic therapy.It is believed that resting energy expenditure increases in patients with newly diagnosed tumors, which is related to C-reactive protein and release of inflammatory cytokines. After eflfectjve therapy,resting energy expenditure decreases in some degree.In addition,the stage and differentiation of tumors also affect metabolism.However,there are some conflicts among research findings.The characteristics of energy metabolism and influential factors in patients with tumors are reviewed in this paper.

Objective To study the angiographie characteristics of coronary heart disease (CHD) patients with type 2 diabetes mellitus.Methods 292 patients with CHD underwent a selective angiography were selected,the characteristics of coronary arteriongraphy were compared in CHD patients with type 2 diabetes mellitus and nondiabetic group.Results In type 2 diabetes mellitus group,the degree of stenosis was higher than that in nondiabetic group (78.01% vs 52.32% )(P < 0.05 ), and the rate of three-vessel disease was higher than that in nondiabetic group (59.57% vs 36.42% )(P <0.05).Conclusion The angiographic characteristics were different in CHD patients with or without type 2 diabetes mellitus.Patients with type 2 diabetes mellitus was associated with more severity of lesion and more lesion vessel.

The metabolic change in patients with the malignent tumor differs from that of patients without cancer.The development in energy expenditure of cancer patient was reviewed.REE in cancer patients is higher than that in the normal,although some authors argued that there were no changes in cancer patients. REE is related with many factors,such as the tumor’s size,status,type,location.

Objective To investigate the value of transvaginal ultrasound in the diagnosis of endometrial polyps. Methods One hundred and ten patients diagnosed as endometrial polyps by transvaginal ultrasound and undergone operative hysteroscopy and histologic examination, were analyzed retrospectively.Results Among 110 cases 75 cases (68.2%) were accurately diagnosed by transvaginal ultrasound,while 35 cases (31.8%) were misdiagnosed.The diseases misdiagnosed included endometrium hyperplasia,intrauterine adhesions and submucousmyoma.Conclusions Combining clinical symptoms with ultrasonogram characters and optimal time of detection can reduce the misdiagnostic rate of endometrial polyps.

Respiratory viral infections are the most common cause of infantile wheezing, as well as one of the major inducents of acute exacebarbations of chronic childhood asthma. Recent studies focus on the mechanism of virus-induced airway inflammatory response which is still not completely clear. Many new pathophysiologic mechanisms such as epigenetics are advanced to explain the association between viral respiratory infections and asthma attack. In the present reports, recent data on the role of early-life viral infections in the development and progression of childhood asthma are reviewed.

Overnutrition during the early postnatal life,a critical time window for growth and development,may induce metabolic syndrome later in life,including overweight/obesity and insulin resistance.The important target organs of insulin,such as liver,adipose tissue,skeletal muscle,and central nervous systems show insulin resistance.The involved mechanisms include abnormality of insulin signal pathway,increment of free fatty acid and some adipocytokines,oxidative stress,maladjustment of orexigenic and anorexigenic neuron,modifications of the hypothalamic-pituitary-adrenal glucocorticoid axis as well as epigenetic,etc.Hence,overnutrition should be avoided during the early postnatal life,so as to decrease the risk of developing long-term insulin resistance.

Objective To observe and analyze the characteristics and trends of the liver and gallbladder damage caused by long-term use of anti schizophrenia drugs through the observation of the abdominal ultrasound. Methods From August 2013 to April 2016, the patients diagnosed as schizophrenia and met criterions were enrolled in our hospital. The observation group I included patients taking anti schizophrenia drug for 3 to 5 years. The observation group II included patients taking anti schizophrenia drug more than 5 years. In addition, the control group recruited healthy person who were over 30 years old and had never taken anti-schizophrenia drug. The change in ultrasound of liver and gallbladder were recorded and analyzed. Results The rate of cholecystolithiasis, chronic cholecystitis in observation group II were higher than those in the other two groups (P<0.05), while there had no significant difference between observation group I and control group. The rate of pure fatty liver in observation group II were higher than those incontrol group (P<0.05), while there had no significant difference between observation group I and observation group II, and there had no significant difference between observation group I and control group. There had no significant difference among three groups regarding as the rate of hepatic cyst and hepatic cavernous hemangioma. Conclusion Long-term use of anti-schizophrenia drugs could increase the risk ofcholecystolithiasis, chronic cholecystitis and pure fatty liver .
