Objective To analyze the experience of Yang Boliang for the treatment of dysentery. Methods The prescriptions for dysentery that used by Yang Boliang were collected to build a database, and analyzed by the unsupervised data mining methods, such as apriori algorithm, entropy Clustering complex systems. Results Based on the analysis of 35 prescriptions, the most frequently used drug, the core drug combinations and the new prescriptions were mined from the database. The most frequently used drugs were tuckahoe, rhizoma pinellinae praeparata, and roasted radix puerariae. The core drug combinations were“tuckahoe- radix scutellariae-moutan bark”, “plantago seed-rhizoma pinellinae praeparata-maticated leaven”, and “charred radix aucklandiae-charred radix etrhizoma rhei-waterlily leaf”, etc. The new prescriptions were such as “plantago seed-rhizoma pinellinae praeparata-maticated leaven-charred radix rehmanniae recen-processed rhizoma Cyperi”. Conclusion Yang Boliang was well experienced in treating dysentery by using the drugs with clearing heat, and drying dampness, and clearing dampness by promoting diuresis.

Objective To assess the accuracy and repeatability of real-time three-dimensional eehoeardiography (RT-3DE) for the measurements of left ventricular (LV) mass in elderly patients compared with magnetic resonance imaging (MRI).Methods A total of 31 patients (26 men) aged ≥60 years (72.1±6.6) years with various cardiovascular diseases were evaluated by MRI and RT- 3DE on the same day.RT-3DE was performed with a Philips iE-33 echocardiographic system, and LV mass was analyzed with the assistance of TomTec software.The results of LV mass obtained by manual tracing were compared with Signa 1.5-T MRI data.The acquisition of RT-3DE datasets was feasible in all 31 patients.Results A good correlation was observed between RT-3DE data with manual border detection and MRI for LV mass (r=0.869, y=0.943 x+11.69, SE= 19.09 g, P< 0.01), with a mean difference of (4.7±37.7)g.The average LV mass was (123.9±35.0)g (74.4-208.1 g) evaluated by MRI, and was (128.6±37.9)g (67.0-222.9 g) evaluated by RT-3DE.There was good inter- or intra-observer correlation between RT-3DE by two sonographers for LV mass.Conclusions The assessment of LV mass from RT-3DE data is feasible in elderly patients.The mass can be determined with high accuracy and low interobserver variability in elderly patients with adequate eehocardiographic image quality.

Objective To analyze the rules of property of the drugs used by State Medical Master Yan Zhenghua in clinical.Methods The prescriptions used by Pro. Yan were collected to build a database, which was based on traditional Chinese medicine inheritance assistant software. After analyzed by the software, such as using the module to analyze the prescriptions, the medication characters of the prescriptions can be got from the database.Results Drugs of warm nature were used with the highest frequency 7998 times, followed by the cool 7866 times, leveling 6763 times, cold 3942 times, and hot 95 times. From the property of five flavors, the most used flavor of drugs was bitter 15260 times, followed by sweet 10810 times, pungent 10453 times, sour 2794 times, salty 1651 times, mild 1203 times, and astringency 186 times. In the frequency of the channel tropism involved, the highest is of liver channel 14237 times, followed by lung 10452 times and spleen 10061 times.Conclusion Pro. Yan was accustomed to using the drugs that were of warm and cool natures, and sweet and pungent flavors, and also the drugs that have action on the collateral channels of liver, lung and spleen, which were the same as the experience from Pro. Yan.

Objective To explore the medication rules of State Medical MasterYan Zhenghua. Methods The prescriptions containing Radix Paeoniae Alba that prescribed by Pro. Yan were collected to build a database based on traditional Chinese Medicine(TCM)inheritance assist system. After analyzed by the statistical reports module and the data analysis module which were from TCM inheritance assist system, and the methods of data-mining that including association rules and apriori algorithm, the frequency of single medicine, the frequency of drug combination, the association rules between drugs and core drug combinations which all were including Radix Paeoniae Alba can be get from the database.Results The prescriptions including Radix Paeoniae Alba were commonly used to treat megrim, stomach-ache, acid regurgitation and other syndromes. The highest frequency used drugs were Radix PaeoniaeRubra, PericarpiumCitriReticulatae, Radix SalviaeMiltiorrhizae, Radix AngelicaeSinensis, Poria, and so on. The most frequency drug combinations were “RadxPaeoniae Alba, Radix PaeoniaeRubra”, “Radix SalviaeMiltiorrhizae, Radix Paeoniae Alba”, and “Radix Paeoniae Alba, PericarpiumCitriReticulatae”. The drug association rules that the confidence was more than once were “Radix PaeoniaeRubra - Radix Paeoniae Alba”, “OsDraconis - Concha Ostreae”, “Radix AngelicaeSinensis,RadixPaeoniaeRubra - Radix Paeoniae Alba”, and “Radix PaeoniaeRubra, HerbaTaxilli - Radix Paeoniae Alba”, and so on.Conclusions The drugs in the prescriptions containing Radix Paeoniae Alba that built by Pro.

Objective To assess the left ventricular(LV) volumes and function acquired by realtime (RT) three-dimensional echocardiography (3DE) versus magnetic resonance imaging (MRI) in elderly patients.Methods A total of 31 patients aged≥60 years [mean (72.1±6.6) years] with various cardiovascular diseases were evaluated by MRI versus RT-3DE on the same day.RT-3DE was performed with a Philips iE-33 echocardiographic system,and LV volumes and function were analyzed with the assistance of TomTec software.The results of LV volumes and function obtained by manual tracing were compared with Signa 1.5-T MRI data.The acquisition of RT-3DE datasets was feasible in all 31 patients.Results The average MRI-detected LV end diastolic volume (LVEDV) was (139.1 ±40.8) ml,LV end systolic volume (LVESV) was (77.8±41.7)ml,LV ejection fraction (LVEF) was (47.9±14.3)％.The average RT-3DE-detected LVEDV was (119.5±37.7) ml,LVESV was (65.5±36.1) ml,LVEF was (47.9± 14.3)％.Compared with MRI values,LVEDV was underestimated by RT-3DE (P＜0.01,r=0.79,y=0.73 x+17.8,SEE=23.5 ml),with a mean difference of (-19.6±25.6)ml; LVESV was also underestimated by RT-3DE (P＜0.01,r=0.89,y =0.77 x+ 5.6,SEE=16.8 ml),with a mean difference of(-12.3± 19.1)ml.Ejection fraction determined by MRI was the same as that by RT-3DE (P＞0.05,r=0.91,y=0.75 x+ 13,SEE=5.61％),with a mean difference of (1.1±7.4) ％.There was good interobserver reproducibility in LV volume detected by RT-3D.Conclusions Compared with MRI,RT-3DE has more accuracy and repeatability in assessment of LV volume and ejection fraction in elderly patients.

Objective To compare postoperative adjuvant chemoradiotherapy with adjuvant chemotherapy in patients with gastric cancer by a meta-analysis.Methods PubMed,EMbase,Cochrane Library,Wanfang,CNKI,VIP,and CBM databases were searched to identify the controlled clinical trials of postoperative adjuvant chemoradiotherapy versus adjuvant chemotherapy for gastric cancer.The obtained data were analyzed using RevMan 5.2.5 and Stata 12.0.The difference between two groups was estimated by calculating the odds ratio (OR) with 95％ confidence interval (CI).Results A total of 12 controlled clinical trials involving 1674 gastric cancer patients,which were selected according to inclusion and exclusion criteria,were included in this meta-analysis.The meta-analysis showed that the 3-and 5-year survival rates were significantly higher in the adjuvant chemoradiotherapy group than in the adjuvant chemotherapy group (OR=2.96,95％ CI=1.75-5.03,P=0.000; OR=1.45,95％ CI=1.06-1.99,P =0.020);the local recurrence rate was significantly lower in the adjuvant chemoradiotherapy group than in the adjuvant chemotherapy group (OR =0.50,95％ CI =0.34-0.72,P =0.000) ; there was no significant difference in distant metastasis rate between the two groups (OR =0.79,95％ CI =0.58 -1.07,P =0.130).Conclusions The meta-analysis of existing study results shows that compared with adjuvant chemotherapy alone,adjuvant chemoradiotherapy is a relatively safe and effective postoperative treatment for gastric cancer.
