Beta-Elemene is an antitumor drug which is isolated from the traditional Chinese medicinal herb Curcumae Phaeocaulis Rhizoma, it is the main component of elemene which is extracted from the plant and delivered via blood circulation after intravenous injection. The antitumor effect of beta-elemene in vitro and in vivo was definite, and beta-elemene could improve the patient immunity and no sever side effect, drug resistance or bone marrow suppression were found during the clinical studies. And human serum albumin (HSA) is a primary extracellular protein which has a high concentration distribution in blood plasma and has many characteristic physiological functions. Therefore, the binding of beta-elemene to protein may be very important for absorption, distribution, metabolism and elimination. Therefore, the study on the interaction of beta-elemene with drug-carrying protein is very important. In this work, molecular binding of beta-elemene to human serum albumin (HSA) was investigated by using spectrofluorometer. the binding constants suggested that a strong interaction and the formation of a complex between beta-elemene and HSA. This clearly implies that beta-elemene can be stored and removed by the proteins in the body. Furthermore, the fluorescence quenching results showed that the HSA fluorescence was quenched by beta-elemene through static quenching mechanism. Thermodynamic parameters showed that hydrophobic interactions play a role in the binding of beta-elemene to HSA. The negative deltaH(0) and positive deltaS(0) in case of beta-elemene therefore showed that electrostatic attraction play a role in the binding of beta-elemene to HSA.

OBJECTIVE:
To assess the effect of one-stage repair of secondary nasolabial deformity and nasal septoplasty for cleft patients on nasal airway resistance (NAR).
METHOD:
Using active anterior rhinomanometry, NAR was measured in eighteen patients with cleft lip and palate who suffered form one-stage repair of secondary nasolabial deformity and septoplasty at per-and-post operation.
RESULT:
NAR was (0.664 +/- 0.200) kPa/(s x L) before operation, (0.304 +/- 0.180) kPa/(s x L) six months after operation, and (0.396 +/- 0.250) kPa/(s x L) twelve months after operation respectively. The differences are statistically significant (P < 0.01) between the NAR before and after operation. Subjective impression score of nasal patency was 7.5 +/- 1.5 before-operation, 2.1 +/- 2.0 after-operation for six months, 3.0 +/- 2.4 after-operation for twelve months. There are significant differences in the subjective impression score of nasal patency as well (P < 0.01).
CONCLUSION
Correction of septal deformities play a very important role in the operation for secondary nasolabial deformity, which can decrease NAR and improve the subjective impression of nasal patency.

Objective: To investigate the incidence of CMV infection(CMV-I) and CMV related diseases (CMV-D) after allogeneic hematopoietic stem cells transplantation in 70 consecutive allogeneic hematopoietic stem cells transplantation(allo-HSCT) patients and to search for the optimal prophylactic strategy.Methods: Blood samples were monitored using the CMV pp65 antigenemia assay.Of the 70 patients observed,30 patients with chronic myeloid leukemia[CML:CP(27),AP(2),BC(1)],12 with acute myeloblastic leukemia(AML),10 with acute lymphoblastic leukemia(ALL)and other cases were NHL(3), AA(5), MDS(7), SCLC with pancytopenia (1),CLL(1), and MF (1). Sixty six patients received HLA - identical siblings transplantation and four received tranplants from their HLA- haploidentical donors. Seventy cases included allo-PBPCT (64 cases) , allo-BMT (4 cases) and allo-PB+BMT (2). Before transplantation, all patients and donors received CMV serological examination except 4 pairs of donors/recepients. All 66 patients (3 cases were CMV IgM positive) and 64/66 donors were CMV IgG positive. Results:After transplantation, 64/70 patients developed CMV viremia during monitoring period. Forty three of 70 patients developed CMV-D.Thirty five of them suffered from CMV-associated interstitial pneumonia(CMV-IP). The high peak levels of CMV antigenemia were associated with development of CMV disease . Close correlation was found between acute graft vs host disease(GVHD) and CMV disease. The patients were followed up for 2 to 24 months. The patients who received preemptive therapy(group A)had significantly better outcome than CMV disease group(group B, P=0.0001). Conclusions: The results suggest that CMV antigenemia has high predictive value for subsequent CMV disease and CMV pp65 antigenemia -guided early therapy has particular advantage for avoiding morbidity and mortality caused by CMV disease.

Pharmaceutical market is a typical market with information asymmetry, and which can lead to "lemons" problem. In all developed countries, firms must receive regulatory approval to market a pharmaceutical product. Such administrative department including SFDA, EMA, FDA and so on. Chinese materia medica is a special part of pharmaceutical market in China. The management of Chinese materia medica is a special challenge in China.
