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 .

It belongs to the ethics that depending to much on high-tech instruments in diagnoses of diseases and overlooking medical examination and clinical history. In clinic educations, we should train medicos to envisage the effects of high-tech instruments in diagnoses of diseases, and strengthen their feeling of responsibility and training of clinic basic shills.

Objective To observe the clinical efficacy of intradermal needle therapy in treating chronic pharyngitis.Method Sixty patients with chronic pharyngitis were randomized into a treatment group and a control group, 30 cases in each group. The treatment group was intervened by intradermal needle therapy at Lieque (LU 7) and Zhaohai (KI 6), while the control group was by Compound Borax solution plus Cydiodine Buccal tablets. The symptoms were scored before and after treatment, and the clinical efficacies were compared.Result The total effective rate was 93.3% in the treatment group versus 80.0% in the control group, and the difference was statistically significant (P<0.05). The symptom scores were markedly changed after the treatment in both groups (P<0.01). The symptom score of the treatment group was significantly different from that of the control group (P<0.05). Conclusion Intradermal needle therapy is an effective method in treating chronic pharyngitis.

Parenteral nutrition associated cholestasis (PNAC) mainly occurs in children. Currently identified risk factors include premature infants, lack of enteral feeding, repeated infections, and toxicity or nutrient deficiency of parenteral nutrition solution. Recent studies have shown that nuclear receptor-mediated bile acid transporter may be the key site of PNAC pathogenesis, in which some cytokines play important roles. New anti-cholestatic therapy based on the regulation of expression of these molecules may prevent end-stage liver disease caused by PNAC.

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.
