The formula-factors concept was put forwarded in this article on account of the syndrome-factors theory. While the prescription compatibility principles "correspondence between syndrome and formula factors" was deduced form the differentiation of syndrome and treatment principles "correspondence between syndrome and formula". Founding on these concepts,the relation between "correspondence between syndrome and formula factors" and "principal,adjuvant,auxiliary and conductant ingredirnts" was approached on the prescription compatibility. And the result was that both compatibility principles above were interweaving associated for their supplementing each other. This conclusion was significative to the prescription compatibility theory as well as TCM clinical practice.

Objective: To analyze the influencing factors of whole blood colloid osmotic pressure (COP) and predict reference range of plasma protein for safe COP to guide clinical infusion of protein in critically ill patients. Methods: Physical data and blood gas analysis of 405 patients were collected. hTe patients were divided into 2 groups by COP: group A (COP≤18 mmHg) and group B (COP>18 mmHg). The serum proteins including total protein (TP), albumin (Alb), globumin (Glb) and ifbrinogen (FIB) were detected. Results: APACHE II of group B was signiifcantly lower than that of group A (P<0.05). hTe survival rate, TP, Alb, Glb and FIB of group B were significantly higher than these of group A (P<0.05).Standardized regression coeffcient of Alb, Glb and FIB was 0.518,0.283 and 0.113 (P<0.05); the 95% reference range of 4 types of protein level in group B: Alb>23.3 g/L,Glb 12.6-37.6 g/L and FIB 1.3-8.7 g/L; 5 reformed equations were made. Conclusion: The main influencing factors of COP include Alb, Glb and FIB. We can use the reference range of 4 types of protein level to guide the clinical management of protein agents, and reformed equations can be used to preliminarily forecast COP in critically ill patients.

CMV related matrix protein pp65 antigenemia was screened in 100 Allo HSCT patients after transplantation. As control groups, samples from fourteen autologous HSCT patients, seventeen patients with various hematological malignant disorders, as well as twenty seven normal donors also were detected. CMV antigenemia was found in 91/100 Allo HSCT patients (91%) after transplantation. 56 % patients with antigenemia developed CMV disease. 54% patients developed acute GVHD. In 87 patients survived more than three months, 52 9% patients developed chronic GVHD. After follow up 18(4～36) months post transplantation, 21 patients died of CMV related diseases. Compared with autologous and non transplantation patients, CMV antigenemia and CMV diseases were particularly associated with Allo HSCT patients. It was obviously correlated with acute and chronic GVHD. CMV infection is a major factor affecting the clinical outcome of Allo HSCT patients.

Aim To study the characteristics of the binding reaction of Troxetutin with bovine serum albumin (BSA) by fluorescence and ultra violet-visible absorption spectra.Methods The quenching mechanism of the fluorescence of BSA by troxerutin was studied with fluorescence.To determine the dynamic quenching constants and static binding constants,the Stern-Volmer equation and the double reciprocal Lineweaver-Burk equation were applied. The number of binding site was calculated with double logarithmic equation and the main binding force was discussed by thermodynamic equations. The binding distance and energy transfer efficiency between donor (BSA) and acceptor (troxerutin) were obtained effectively quenched fluorescence of BSA via static quenching processes. The binding constant Ka was calculated to be in the order of 106,indicating a strong interaction between Troxerutin and BSA. The number of binding site was approximately equal to 1,the binding distance was 1.97 nm,the energy transfer efficiency was 0.529,and the binding force was mainly hydrophobic force.Conclusion Troxerutin effectively quenchs the intrinsic fluorescence of BSA via static quenching mechanism,and the binding is mainly driven by the hydrophobic interaction.
