OBJECTIVE:To explore the transform of the medicinal properties of Coptis chinensis-Cinnamomum cassia couplet medicines before and after mixing. METHODS:Mice were randomly divided into normal group,weak constitution (induced by food restriction and swimming) group,weak constitution+C. chinensis group,weak constitution+C. cassia group,weak constitu-tion+couplet medicine group,prosperous constitution (induced by high protein diet) group,prosperous constitution+C. chinensis group,prosperous constitution+C. cassia group and prosperous constitution+couplet medicine group,with 10 mice in each group. After modeling,each group was given relevant medicine intragastrically by 20 g(crude drug)/(kg·d),and normal group was giv-en equivalent volume of normal saline intragastrically for consecutive 7 days. The proportion of rats remained in high-temperature ar-eas was recorded. Organ index,biochemical index(Na+/K+-ATPase,Ca2+/Mg2+-ATPase),total antioxidant capacity(T-AOC),SOD activity,the serum content of noradrenalin and dopamine were detected. RESULTS:Compared with normal group,proportion of mice in high-temperature area increased in weak constitution group,while liver index,spleen index,renal index,biochemical in-dex activity or content decreased(P<0.05);the change of above index in prosperous constitution group were opposite to weak con-stitution group;above index had statistical significance except for the proportion of mice in high-temperature area(P<0.05). Com-pared with weak constitution/prosperous constitution group,the proportion of mice remained in high-temperature area and liver in-dex increased in weak constitution/prosperous constitution+C. chinensis group,while biochemical index activity or content de-creased(P<0.05);the change of above index in weak constitution/prosperous constitution+C. cassia group were opposite to C. chi-nensis group,spleen index and renal index increased(P<0.05);the proportion of rats remained in high-temperature area increased in weak constitution/prosperous constitution couplet medicine group,and biochemical index activity or content decreased,among which total antioxidant activity decreased significantly(P<0.05). CONCLUSIONS:The couplet medicine manifests the“cold na-ture”after C. chinensis and C. cassia equally paired,because“hot nature”degree of C. cassia is lower than“cold nature”of C. chi-nensis.

AIM: The fingerprint chromatograms were established for quality evaluation of Desmodium styracifolium collected from 11 areas by HPLC. METHODS: The analysis was performed on a Phenomsil C_(18) column((4.6 mm)?250 mm,5 ?m) with acetonitrile-carbinol-water as mobile phase in a gradient mode at a flow rate of(1.0) mL/min,and at a column temperature of 25℃.The detection of wavelength was at 272 nm. RESULTS: 11 peaks were selected as the common fingerprint peaks.The relative standard deviations for relative retention values and relative peak areas were less than 3% in the precision and repeated test,the similarity of 11 batches of samples were no less than 0.9. CONCLUSION: The method is reliable and can be helpful on the quality control of Desmodium styracifolium.

AIM: To establish the method of fingerprinting analysis on Zedoary turmeric oil by GC.Zedoary turmeric oil for the quality control of reference. METHODS: GC method was used to determine the fingerprint and its similarity of Zedoary turmeric oil calculated on Excel and cluster analysis. RESULTS: Seventeen samples of Zedoary turmeric oil indicated that there was a little similarity among them.Based on the cluster analysis,all the Zedoary turmeric oils could be divided into two categories,self-made and market purchasing oil,the latter oils purchased from Liaoning province and Jiangsu province varied considerably.Every category had a common fingerprint mode with clear resemblance. CONCLUSION: When finding the difference between the self-made and the market purchasing Zedoary turmeric oil,quality control requires serious consideration.

AIM:To establish the method for determining oridonin and rosemarinic acid in Donglingcao Tablets(Rabdosia rubescens(Hemsl.) Hara). METHODS:Oridonin and rosemarinic acid were determined by HPLC simultaneously with changing ultraviolet-visible wavelength.Chromatographic condition was composed of ODS-C_(18) column,methanol-03.% phosphoric acid (40∶60),UV detection wavelength of oridonin at 238 nm and of rosemarinic acid at 329 nm. RESULTS:The average recoveries were 97.8% and 96.7% and related standard deviations(RSD) were 1.9% and 2.3%. CONCLUSION:This method can be used to determine simultaneousely oridonin and rosemarinic acid in Donglingcao Tablets.

Objective To investigate the effectiveness of treating postherpetic neuralgia (PHN) by intradermal drug injection.Methods Ten rabbits of both sexes weighing 2.3-2.8 kg were anesthetized with intravenous urethane 1.5 g/kg. In group A (n = 5) 30% horseradish peroxidase(HRP) 500 ?l and in group B (n = 5) 1%-2% fluorescent nuclear yellow (NY) 500?l were injected intradermally at 6-8 points along the both sides of spine in the scapula region. After 48-72 h the animals were sacrificed and C4 -T10 spinal ganglia, cervical and thoracic sympathetic ganglia and celiac ganglia were harvested for identification of labeled neurocytes. Results Labeled neurocytes were found in C4-T10 spinal ganglia, cervical and thoracic sympathetic ganglia and celiac ganglia. There were more labeled neurocytes in the C6-T8 spinal ganglia. There were more labeled neurocytes in the sympathetic ganglia than in the spinal ganglia. The distribution of fluorescent labeled neurocytes corresponded to neurocytes labeled by HRP method. At the same segment there were more fluorescent labeled neurocytes than neurocytes labeled by HRP. Conclusion There is an ascending axoplasma streaming channel from nerver ending to the neurocytes in the ganglion as shown by morphological study and the good therapeutic effect of intradermal drug injection in the treatment of PHN may be related to this channel.

AIM: To use seven parts cortex phellodendri and one part Rhizoma atractrylodis to extract mixedly,and study mouse's pharmacokinetic parameter of berberine derived from extract. METHODS: Evodiamine was taken as the marker,HPLC was used to determine berberine content in rat plasma. RESULTS: The linear range of rat's plasma sample was within 0.006 6-0.211 2 ?g/mL,RSD was little than 10%,detection limit was 0.0033 ?g/mL.The main pharmacokinetic parameters consisted of 2 h(T_max),0.183 mg/L(C_max),10.87 h(MRT_0-24),21.562?4.448(MRT_0-∞). CONCLUSION: Berberine in combination of cortex phellodendri and Rhizoma atractylodis can be quickly absorb and achieve the peak value,but metabolize slowly.

To analyze the relationship among ambulatory blood pressure (AMBP), ankle brachial index (ABI) and left ventricular mass index (LVMI) in hypertensive patients. Methods 578 hypertensive inpatients were reviewed. Results The general clinical dataof selected patients, their ABI, LVMI were not different significantly between male and female. The correlation analysis showed that LVMI was positively correlated with the 24-hour average systolic (r=0.245, P=0.000) or diastolic (r=0.158, P=0.000) blood pressure, whereas negatively correlated with percent of systolic (r=－0.104, P=0.012) or diastolic (r=－0.132, P=0.001) blood pressure declining at night. No significant correlation was found between LVMI and BMI. Multiple regression analysis revealed that LVMI was significant independently positive correlated with 24-hour average systolic blood pressure (P=0.000). Conclusion LVMI does not correlate with ABI, but independent positive related with 24-hour average systolic blood pressure.
