This study was aimed to find the correlation between amino acid compositions and Cold-Heat Nature of traditional Chinese medicine (TCM) in order to provide basis for the research of TCM natural theory. A total of 17 kinds of amino acid were determined by application before column derivatization reaction and high-perfor-mance liquid chromatography (HPLC) and the tryptophan was determined by UV method. The data were collected for analysis by Fisher method in PAST software. The best statistical identification model was determined. And the Cold-Hot medicine property markers (CHMP-markers) were determined. The results showed that the discriminant function established by Fisher method based on 18 kinds of amino acid contents has good identification ability, and the accuracy of the Fisher discriminant analysis is 82%. Support vector machine (SVM) is the best statistical identification model . The cold and heat markers were analyzed by SVM . The cold nature material bases in-clude Glu, Gly, Arg, Thr, Ala, Tyr, Val, Ile and lys. And the heat nature material bases contain Asp, Ser, His, Pro, Met, Cys, Leu, Phe and Trp. It was concluded that there is relationship between 18 kinds of amino acid contents and the Cold-Heat nature of TCM .

Objective To explore the molecular mechanisms of primary amenorrhea by using arrayCGH technology. Methods Ten patients with primary amenorrhea and 10 female volunteers with regular menstrual cycles as healthy controls were selected. All patients and control samples were analyzed by conventional chromosome analysis (G-banding technology) and array-CGH technology, respectively. ArrayCGH was performed using Affymetrix Cytogenetic 2. 7M arrays following the manufacturer's standard protocol. Results Both the patient group and control group analyzed by conventional G-banding karyotype technology showed a negative result with a normal female karyotype: 46, XX. The result of array-CGH analysis demonstrated a microdeletion of approximately 110 000 bp located at the end of the short arm of X chromosome [46, X, del (X) (p22. 33 )] were identified in 5 patients, which was not detected in the control group. All healthy control samples by array-CGH analysis showed no pathological DNA copy number variation. Conclusions Array-CGH technology can improve the diagnosis rate of chromosomal disease at the DNA level. It is necessary to provide array-CGH for higher resolution genetic analysis of idiopathic primary amenorrhea patient who can not be identified by conventional technology.

OBJECTIVE:To establish the HPLC characteristic chromatogram of pheretima,and compare the differences of the main ingredient contents of Guangdong pheretima and Shanghai pheretima and the chromatogram differences among pheretima and 3 other animal drugs. METHODS:Pheretima HPLC characteristic chromatogram method was adopted to determine the characteris-tic chromatograms of 16 Guangdong pheretima,8 Shanghai pheretima,3 eupolyphaga,3 hirudo and 3 catharsius. Similarity evalua-tion and t test were used to analyze the differences of chromatogram data of 5 animal drugs. RESULTS:The established HPLC char-acteristic chromatogram method firstly identified 11 common characteristic peaks,including 6 nucleosides,4 nucleobase and 1 ami-no acid;and it could be used for the identification of pheretima from eupolyphaga,hirudo and catharsius;the differences of main ingredient contents in the characteristic chromatogram of Guangdong pheretima and Shanghai pheretima were firstly studied. The contents of xanthine and adenosine in Guangdong pheretima were higher than Shanghai pheretima,while the contents of uridine, guanosine and 2′-deoxy guanosine in Shanghai pheretima were higher than Guangdong pheretima. A new index S,calculated by these 5 constituents,was successfully applied to distinguish the 2 kinds of pheretima. CONCLUSIONS:The characteristic chro-matogram can be used for the identification of pheretima,and can provide reference for the pharmacodynamic differences study of Guangdong pheretima and Shanghai pheretima.

Objective To establish blood purification system for rats and provide a safe and reliable experimental platform for further research of blood purification. Methods The right carotid artery and the contralateral jugular vein of adult male Sprague?Dawley rats were cannulated to creat vascular access for blood purification, by which continuous arteriovenous hemofiltration blood purification system was established. Blood flow, substitution fluid flow and ultrafiltration rate were regulated by rotary mini?pumps. Blood purification therapy continued for 4 hours on the basis of maintained anesthesia and effective anticoagulation. The safety of continuous arteriovenous hemofiltration blood purification systems was evaluated by comparing the arterial blood gas, electrolyte indexes and blood glucose during the blood purification therapy. Closely monitoring the vital signs of rats, such as blood pressure and heart rate, and observing whether there were any side effects, such as massive haemorrhage, thrombogenesis and gas embolism in the therapeutic process. Results There were no obvious changes of arterial blood gas, electrolyte indexes and blood glucose during the blood purification therapy (P>0.05). The vital signs did not fluctuate acutely before and after the blood purification therapy (P>0.05). The incidence rate of side effects was very low. Conclusions
Continuous arteriovenous hemofiltration blood purification system had no obvious adverse effects on healthy rats. Our blood purification system for rats appears to be safe and reliable.

Objective:To investigate the expression and significance ofβ1 integrin, Rac1, and RhoA in invasive micropapillary breast carcinoma (IMPC). Methods:Immunohistochemical staining was performed to detect the expression ofβ1 integrin, Rac1, and RhoA in 89 patients with IMPC and 90 patients with invasive ductal carcinoma-not otherwise specified (IDC-NOS) who were treated between January 2007 and December 2008 in Tianjin Medical University Cancer Institute and Hospital. The relationship among the three proteins and the expression ofβ1 integrin, Rac1, and RhoA with clinicopathological features were determined. Results:β1 integrin (78.7%) and Rac1 (76.4%) were highly expressed in patients with IMPC. This expression was significantly higher than that in patients with IDC-NOS (63.3%and 54.4%). Statistical difference was found between the two groups (P<0.05). Positive rate of RhoA (68.5%) in patients with IMPC was also statistically higher than that in patients with IDC-NOS (44.4%, P=0.001). In patients with IMPC, the expression ofβ1 integrin and Rac1 was positively associated with lymph node metastasis (P<0.05), while the expression ofβ1 integrin was positively correlated with Rac1 expression (P=0.006). Expression of RhoA was positively correlated with lymph node involvement and ER and PR status (P<0.05). However, no correlation was found between RhoA expression and the expression ofβ1 integrin and Rac1 (P>0.05). Conclusion:Thus,β1 integrin, Rac1, and RhoA were overexpressed and might play an important role in the high frequency of metastasis in patients with IMPC. These proteins could be considered as biomarkers for the prognosis and new targets for IMPC therapy.
