To study the anti-coagulant effect and influence of danggui Sini decoction (DSD) on rat's plasma endogenous metabolites by animal experiment and ¹H-NMR based metabolomics method. After intragastric administration of Danggui Sini Decoction for 7 days, Plasma thrombin time (TT) was measured. Rat plasma metabolic fingerprint in two groups was analyzed using ¹H-NMR, based on which the principal component analysis( PCA) and orthogonal partial least-squares discriminant analysis(OPLS-DA) models for metabonomic analysis. Potential biomarkers were screened by using variable importance in the projection (VIP) and T test. DSD could prolong TT of the rat significantly (P < 0.05). Compared with control group, six kinds of endogenous metabolites in DSD group change significantly (P < 0.05), among which isobutyrate, carnitine and phenylalanine content had an upward trend (P < 0.01) and lysine, Histidine and cholesterol content had a downward trend (P < 0.05). It is likely that carnitine, phenylalanine, Histidine and cholesterol are the potential metabolic markers in the anti-coagulant process and DSD affects the platelet aggregation and the expression of tissue factor and fiber protease by regulating the energy, amino acid and lipid metabolism.

OBJECTIVE:
To explore the effect of ulinastain on the expression of hemeoxy genase-1 (HO-1) in oil acid-induced acute lung injury in rats.
METHODS:
The animal model of acute lung injury was established by oil acid. Thirty SD rats were randomly divided into 3 groups: the blank control group (A), the acute lung injury group (B) and the acute lung injury group (C) followed by injecting 100 mL/kg ulinastatin. Each group consisted of 10 rats. Group A were given 0.2 mL/kg natural solution through the trial vein; Group B and C were given 0.2 mL/kg oil-acid through trial vein, while group C were injected 100mL/kg ulinastatin by the peritoneal cavity after injecting oil acid. After 4 hours, the rates of respiration were counted and blood samples were cramped out through the heart puncture for blood gas analysis. The expressions of hemeoxygenase-1 and the pathologic construction changes were determined by HE staining in the lower right lung of rats in the 3 groups.
RESULTS:
The respiration dysfunction caused by oil acid could be prominently improved by ulinastain. There was only a little expression of hemeoxygenase-1 in the lung of Group A, but the expression increased in Group B and significatively increased in Group C.
CONCLUSION
Ulinastatin may protect the rats from acute lung injury through increasing the expression of HO-1.

OBJECTIVETo explore the effect of one dressing of porcine acellular dermal matrix on deep partial thickness burns.
METHODSFrom January 1997 to January 2004, sixty-seven cases of deep partial thickness total burned surface area (TBSA) from 50% to 90% burn wound were treated by a single dressing of porcine acellular dermal matrix (the porcine acellular dermal matrix group). Ten cases of deep partial thickness burned patients with the same TBSA treated by exposure method served as the exposure method group. The healing time of the wound was observed. The patients were followed up for 3 months to 2 years, and the scar proliferation was observed.
RESULTSThe deep partial-thickness wound would be healed without dressing change in the porcine acellular dermal matrix group, and the average healing time was (12.2 +/- 2.6) days. The average healing time of the exposure method group was (27.4 +/- 3.5) days. Follow up of the patients within 3 months to 2 years showed that scar proliferation in the porcine acellular dermal matrix group was much less than that in the exposure method group, even no scar proliferation was observed in some patients.
CONCLUSIONWithout tangential excision, autografting and dressing change, a single dressing of porcine acellular dermal matrix on deep partial thickness burn wound could shorten the healing time and inhibit scar proliferation.

Cancer-associated fibroblasts (CAFs) are essential parts of tumor stroma. Fibroblast activation protein (FAP), overexpressed in CAFs, is closely related to tumor growth, invasion, metastasis, immunosuppression and prognosis, which is a vital target for tumor targeted diagnosis and therapy. In recent years, a variety of new radiolabeled quinoline-based FAP inhibitors (FAPIs) have been used for tumor targeted diagnostic and therapeutic research. A number of studies have confirmed that radiolabeled FAPIs plays an important role in tumor diagnosis, staging and treatment, which have a good clinical application prospect. This review summarizes the research status of radiolabeled FAPIs and discusses their potential in the accurate diagnosis and therapy of tumors.
