Objective To construct novel 3-D composite bionic network and evaluate the histocompatibility . Meth?ods The novel 3-D composite bionic network was prepared from chitosan, hydroxyapatite, gelatin and pectin in certain ra?tio by biomimtic approach, which was co-cultured with MC3T3-E1. The cell compatibility was studied by using inverted phase contrast microscope, routine paraffin section staining, scanning electron microscopy and F-DA staining. The resultant scaffold material was implanted into the dorsal subcutaneous space of SD rats. The histocompatibility, blood vessel capabili?ties and the degradation of the material were observed 2, 4, 8 and 12 weeks after surgery. Results The structure of novel 3-D composite bionic network was three-dimensional and porous. The cells attached on scaffolds attached and grew well with polygonal or fusiform form. It was found that inflammatory reactions were alleviated gradually in the early stage . There was an increasing angiogenesis at late stage. Materials degraded and absorbed more slowly. Conclusion The present study sug?gests that the novel 3-D composite bionic network has good histocompatibility with easy vascularization, and will be a candi?date scaffold for bone tissue engineering.

The preliminary metabolic profile of total diterpene acid (TDA) isolated from Pseudolarix kaempferi was investigated by using in vivo and in vitro tests. Pseudolaric acid C2 (PC2) was identified as the predominant metabolite in plasma, urine, bile and feces after both oral and intravenous administrations to rats using HPLC-UV and HPLC-ESI/MS(n), and demethoxydeacetoxypseudolaric acid B (DDPB), a metabolite proposed to be the glucoside of PC2 (PC2G), as well as pseudolaric acid C (PC), pseudolaric acid A (PA), pseudolaric acid A O-beta-D glucopyranoside (PAG), pseudolaric acid B O-beta-D glucopyranoside (PBG) and deacetylpseudolaric acid A (DPA) originated from TDA could also be detected. It was demonstrated by tests that the metabolism of TDA is independent of intestinal microflora, and neither of pepsin and trypsin is in charge of metabolism of TDA, TDA is also stable in both pH environments of gastric tract and intestinal tract. The metabolites of TDA in whole blood in vitro incubation were found to be PC2, DDPB and PC2G, which demonstrated that the metabolic reaction of TDA in vivo is mainly occurred in blood and contributed to be the hydrolysis of plasma esterase to ester bond, as well as the glucosylation reaction. These results clarified the metabolic pathway of TDA for the first time, which is of great significance to the in vivo active form and acting mechanism research of P. kaempferi.

PURPOSE: This study was designed to evaluate diagnostic accuracy of serial electrocardiograms(ECG), myocardial band of creatinine phosphokinase(CK)(CK-MB/CK ratio) and two dimensional echocardiography(ECHO) for myocardial injury in patients with blunt chest trauma. METHODS: We prospectively investigated 54 patients(male : 38, female : 16, mean age : 41) with severe blunt chest trauma. Presence of myocardial injury was determined by increase(>0.1ug/L) of peak serum troponin T(TnT) concentration from serial mesurements. RESULTS: Among 54 patients with blunt chest trauma, 23 patients(43%) had increased peak TnT level which suggested of myocardial injury. Among 23 patients with increased TnT, abnormal ECG findings were found in 18(78%) and echocardiographic abnormalities were observed in 17(74%). Cardiovascular events in 9(39%) of 23 patients with increase Tnt. There was no cardiovascular events in patients with normal TnT. CONCLUSION: Significant proprotion of patients with blunt chest trauma had elevated TnT value which suggested of myocardial injury. We recommend echocardiagraphy and serial tracing of ECG to verify the clinical significance of elevated TnT in patients with blunt chest trauma.

The purpose of this study was to evaluate the efficiency of Japan Langerhans Cell Histiocytosis Study Group (JLSG) Protocol in treatment of children suffering from multiple system langerhans cell histiocytosis (MS-LCH). The clinical features, therapeutic response and prognosis of 11 children who were diagnosed and treated by JLSG in our department during October 2004 through October 2011 were analyzed. Among all 11 cases, 8 males and 3 females, the age at diagnosis was from 3 month to 6.5 years old with a median age of 3 years old. There were 10 cases of LCH with multi-system involvement (MS-LCH) and 1 case of single-system involvement (SS-LCH). Among those MS-LCH patients, 5 patients had risk organ involvement, and the other 5 patients did not develop risk organ involvement. All patients had been treated with JLSG protocol. The results showed that 4 cases achieved good response after 6-week induction treatment and the time of drug discontinuation were 5 - 20 months without relapse; 3 cases achieved partial response after 6-week induction treatment, among them 1 case did not relapse after discontinuation of drugs for 19 months, 1 case was still receiving maintenance treatment, 1 case abandoned induction treatment; 4 patients got no response (NR) or progressive disease after 6-week of induction treatment and were switched to salvage therapy, among them, 2 patients had stopped treatment for 2 - 20 months without relapse, 1 patient was still receiving maintenance treatment, one had changed to another therapy. It is concluded that the most of childhood LCH can be effectively controlled by immunochemical therapy based on the JLSG protocol. For children with LCH who has a poor response after 6-week induction treatment, LCH can still be well controlled if switched to salvage treatment.

BACKGROUND: Cardiovascular injury is a potentially fatal complication of blunt chest trauma. The diagnosis of cardiovascular injury in blunt chest trauma is not easy because of concomittent injuries of thoracic cage or lungs and early death from cardiovascular injury. Diagnostic tools such as electrocardiography or cardiac enzyme studies are not specific to cardiovascular injury. Two-demensional echocardiography can visualize anatomic and functional disturbances from cardiovascular injuries in patients with blunt chest trauma. Purpose: This study was designed to evaluate the usefulness of echocardiography in detecting cardiovascular injury of patients with blunt chest trauma. METHODS: We performed echocardiography for detecting cardiovascular injury in 151 patients with significant blunt chest trauma including sternal fracture, multiple rib fractures or pulmonary contusion. Echocardiography was performed within 6 hours since patient arrived emergency department. Electrocardiography was traced on arrival and 24 hours after admission. Serial determinations of cardiac enzymes including MB fraction of creatinine phosphokinase were also performed every 8 hours after admission. RESULTS: 37(25%) patients had echocardiographic evidences of cardiovascular injury. Abnormal echocardiographic findings were 10 pericardial effusion, 9 regional wall motion abnormality(RWMA) outright ventricle, 5 aortic injuries, 4 reduced left ventricular ejection fraction, 3 RWMA of left ventricle, 2 right ventricular dilatation, 2 valve injuries, and 2 other cardiovascular injuries. Electrocardiographic abnormalities were associated with echocardiographic findings. However, CK-MB/CK ratio was not associated with echocardiographic findings. Significant proportion(65%) of patients with abnormal echocardiographic findings needed cardiovascular management during hospital stay. CONCLUSION: Two-dimensional echocardiography is useful for detecting cardiovascular injury. Echocardiographic abnormality in blunt chest trauma is associated with high probability of need of cardiovascular management.
