Objective To investigate the accuracy of computer-assisted interpretation(CAI)in the diagnosis of pediatric critical arrhythmia,and to establish Logistic regression model to evaluate the main risk factors of CAI error.Methods 1147 cases of arrhythmia patients were divided into heart disease(HD)and nonheart disease group(NHD).Candidate risk factors were chosen,from which the vailables statistically significant were entered for logistic regression analysis.Results CAI error rate of HD group and NHD group were 24.9%and 11.4%,showing a significant difference(P＜0.05).Age,underlying diseases,the number of CAI diagnosis entries were the risk factors.Conclusion CAI error pattern was different among HD group and the NHD group.Higher awareness for CAI error risk factors and CAI technology improvement are critical for a lower CAI error rate.

Chinese meteria medica (CMM) chain is a long-span chain covering agriculture which mainly depends on the forces of nature as well as high-tech CMM industry, CMM expertise industry and fast developing CMM circulation industry. Imbalance among the development of these industries produces bottlenecks and hinders the operation of the entire production chain. After analyzing the structure of Chinese meteria medica industrial chain from the perspective of national economy industry, three industry classifications and differentiation of factor intensity, we conclude that the complex structure of CMM industry chain is attributable to these three aspects. And the complexity is mainly shown at complex industry, varied product types, different coordination of various industrial sections and different technical growth speed of varied industry. We propose that structural complexity is the natural property of the chain, which is the main reason of industry sector development imbalance and bottleneck. Results of this research could provide theoretical analysis for future research on the coordination of industrial chain and the efficiency of resource allocation.

Circulation of traditional Chinese medicinal materials, as the vital part of the TCM industrial chain, plays an important role in the connection of agriculture link and industry link of traditional Chinese medicinal materials, which has influence on the healthy development of the whole TCM industrial chain. Because circulation activities mainly include exchange and storage activities instead of manufacturing real products, they are much more difficult to be managed compared with producing activity. This would lead to problems in circulation of traditional Chinese medicinal materials, and impose negative effects on TCM industry. Based on scale economy theory, information asymmetry theory and cobweb model theory, this article analyzed the problems in circulation of traditional Chinese medicinal materials, discussed the deep reasons behind these problems, and proposed relevant suggestions for optimization.

Objective To establish the quality standard of Alatan Wuwei Pill. Methods Chebulae Fructus and Granatii Fructus were identified by TLC. Gallic acid and ellagic acid in Gardeniae Fructus and Granatii Fructus were determined by HPLC. Results The TLC spots developed were clear. Gallic acid showed good linear relationship in the range of 0.058 72-1.056 96 mg (r=1.000 0), the average recovery was 99.15%(RSD=1.3%). Ellagic acid showed good linear relationship in the range of 0.079 64-1.194 6 mg (r=1.000 0), the average recovery was 100.02% (RSD=2.3%). Conclusion The method is simple and reproducible. It can be used to control the quality of Alatan Wuwei Pill.

Objective To study the clinical outcome of breast conserving treatment of breast ductal carcinoma in situ(DCIS).Methods The data of 62 patients with pathologically proven DCIS who underwent breast conserving operation and adjuvant radiotherapy were retrospectively compared with 62 concurrent cases of stageⅠ or Ⅱ infiltrating ducatl carcinoma who received breast conserving operation and adjuvant readotherapy.Results The recurrence rate in DCIS cases was 6.4%(4/62),among them,3 cases belonged to comedo type;the recurrence rate in early infiltrating type of ductal breast carcinoma was 19.3%(11/62)(P

Objective:To observe the effects of soybean isoflavones(SI) on uteri and uterine Er?,ER? expression in perimenopausal rats. Method:Female SD rats in age of 7-month-old were used as control and 11-month-old SD rats were divided into 5 groups,model group,diethylstilbestrol group and 3 test groups exposed to three doses of SI(ig:30,12,4.6 mg/kg?d) respectively for 35 d. Serum concentrations of estradiol(E2) ,testosterone(T) ,follicle-stimulating hormone(FSH) and luteinizing hormone(LH) were determined. Ultrastructure of uterine luminal surface was observed by scanning electron microscopy and hematoxylin-eosin staining. Expression of ER? and ER? in the uteri were determined by immunohistochemistry. Results:Low dose SI significantly increased serum E2(P

Objective To explore the 5,10-methylenetetrahydrofolate reductase( MTHFR) and 5-methyltet-rahydrofolate-homocysteine methyltransferase reductase( MTRR) gene polymorphisms among the Han women in Laiwu City.Methods A total of 559 Han women were recruited.And their oral epithelial cells were collected to extract genome DNA in order to detect gene polymorphisms of MTHFR and MTRR using fluorescence quantitative PCR.Then the results were compared with those in other cities in China.Results The frequency of MTHFR 677CC,677CT and 677TT of Han women in Laiwu city was 14.3%,46.7%and 38.1%,respectively.The frequency of MTHFR 677TT among Laiwu women was significantly different to those of Zhenjiang, Wuhan, Kunming, Deyang, Huizhou, Qionghai (P<0.05).The frequency of AA,AC,CC gene type on MTHFR A1298C was 78.2%,19.7% and 2.1%,respec-tively, the frequency was significantly different to those of Zhenjiang, Wuhan, Kunming, Deyang, Huizhou, Qionghai (P<0.05).The frequency of AA,AG,GG gene type on MTRR A66G was 53.3%,38.8%and 7.9%,respectively. The frequency of MTRR 66GG was significantly different to that of Qionghai(P<0.05).Conclusion The MTHFR, MTRR polymorphism distribution of Han women in Laiwu City has the characteristic of region specificity,respectively.
