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

The MLN64 gene,which is localized in q12-q21 of the human chromosome 17,encodes a novel transmembrane protein containing 445 amino acids .The C-terminus of MLN64 shares significant homology with the steroidogenic acute regulatory (StAR)protein,while its N-terminal domain exhibits a function of targe-ting the protein to late endosomes .MLN64 is likely to be involved in cholesterol transport and synthesis of steroid hormones.MLN64 gene,coamplified with C -erbB-2,is overexpressed in certain breast carcinomas and exerts an influence on biological characteristics of breast cancer cells .The high levels of MLN 64 observed in some breast carcinomas could contribute to the growth and progression of these tumors through increased intratumoral steroido -genesis,and is considered as a predictive factor of breast cancer prognosis .

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.

Perioperative nutrition support may be required when the synthesis and utilization of nutrients become disordered due to gastrointestinal abnormalities and trauma anesthesia. Proper nutrition support can reduce or prevent malnutrition, and thus facilitate the recovery and lower complications and case-fatality rate.

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.

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.
