Research on medication regularity of pattern of internal accumulation of zhuodu in chronic atrophic gastritis based on correspondence between prescription and syndrome / 中草药

To study the medication regularity of Huazhuo Jiedu Formula in treating the chronic atrophic gastritis (CAG), and to explore the stable relationship of correspondence between Huazhuo Jiedu Formula and the pattern of internal accumulation of zhuodu. Statistical analysis was conducted among 200 cases of CAG, whose case histories included their gender, age, electronic gastroscope, pathological results, clinical symptoms, and prescriptions of Chinese materia medica. On the basis of "golden section method", the association rule between drugs and syndromes was investigated using frequency statistic method and association rule analysis. Through data processing, 153 kinds of Chinese herbal decoction were obtained. According to the principle of "golden section method", 15 kinds of Chinese herbal decoction, whose frequency of use was over 61.8% (including 61.8%), were used as the therapeutical core drugs of pattern of internal accumulation of zhuodu in CAG. Ten kinds of clinical symptoms, which had the high ocurrence rate, were the main symptoms of the pattern of internal accumulation of zhuodu in CAG. According to association rules analysis, it was found that there was a strong correlation between drugs and pulses, which explained the high degree of correspondence of prescription and syndromes between the pattern of internal accumulation of zhuodu in CAG and Huazhuo Jiedu Decoction. It can be seen that there exists a relationship of correspondence between Huazhuo Jiedu Formula and the pattern of internal accumulation of zhuodu in CAG. And it shows that the key pathogenesis of CAG is internal accumulation of zhuodu, and the corresponding treatment is Huazhuo Jiedu Method.

Photometric study of divine proportion and its correlation with facial attractiveness

OBJECTIVE: The aim of this study was to evaluate if there is correlation between perception of facial esthetic and divine proportion, verifying if most attractive faces are closer to and less attractive faces are more distant to this proportion. METHODS: Standard facial photographs (frontal and lateral) in natural head position were taken of a sample of 85 Brazilian Caucasian women, with mean age of 23 years and 9 months. The photographs were evaluated by 5 orthodontists, 5 artists and 5 laymen and were classified, according to their subjective analysis of facial esthetic, in pleasant, acceptable and not pleasant. Frontal photographs were evaluated by divine proportion analysis using the computerized method. RESULTS AND CONCLUSIONS: According to subjective analysis the sample consisted 18.8% of pleasant, 70.6% of acceptable and 10.6% of not pleasant faces. After statistical analysis, a lack of agreement was verified in esthetic facial preferences among the three groups of observers.

Dose of expression and study of the theory for adverse reactions of cefamandole nafate for injection- Gold Zone Method / 中国基层医药

Objective Inaccurate dosing is an important cause of medical malpractice, how to adjust the medication dose to overcome the excessive deviation will be discussed in this paper. Methods Gold zone method was proposed on the basis of the probability theory and mathematical statistics for handling inaccurate dosing problems. Investigation and study in large sample size was carried out on adverse reactions of Cefamandole Nafate for Injection by adopting the method. Results The conclusions from the super large sample size test indicate that there is highly significant difference of total adverse reaction rates between taking values within and outside golden zone of dosage, and the adverse reaction rate of taking values within golden zone is significantly lower than that of outside golden zone. It is noteworthy that when dosage was lower than golden zone,the adverse reaction rate was significantly increased,which is more than 4 times of that within golden zone. Conclusion It is effective measures and simply and easy to apply that taking values within golden zone of dosage reduce adverse drug reactions,probability within golden zone less than 1/4 range of experience that contains the actual demand of the body up to 70%.
