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

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.

AIM: To observe the effects of Yangxue qingnao-containing serum on rat vascular smooth muscle cell (VSMC) proliferation induced by lysophosphatidic acid (LPA). METHODS: The [ 3H]-TdR incorporation and mitogen-activated protein kinasc (MAPK) activity were measured in cultured VSMC. End product of lipid peroxidation-MDA levels were also detected. RESULTS: 1?10 -9 ,1?10 -8 and 1?10 -7 mol/L LPA enhanced the cultured VSMC [ 3H]-TdR incorporation, increased MAPK activity and MDA content in a concentration-dependent manner. 5%, 10% and 15% Yangxue qingnao-containing serum concentration-dependently inhibited the increase in VSMC [ 3H]-TdR incorporation, MAPK activity and MDA content induced by LPA. CONCLUSIONS: LPA has a stimulating effect on VSMC proliferation. The LPA-induced intracellular signal transduction may be related to MAPK activity. Yangxue qingnao can efficiently inhibit LPA -induced VSMC proliferation,MAPK activity and lipid peroxidation. [

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.

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.

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.

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.
