BACKGROUNDRecent studies have demonstrated that dexamethasone (DEX) interferes with immune responses by targeting key functions of dendritic cells (DCs) at the earliest stage. However, the cellular and molecular mechanisms are still incompletely understood. This study aimed to explore the possible mechanisms by investigating the roles of DEX on differentiation, maturation & function of murine DCs and the effects of DEX on DCs via Toll-like receptor 4 (TLR4)-nuclear factor (NF)-kappaB mediated signal pathway.

METHODSImmature DCs (imDCs) were cultured from murine bone marrow (BM) cells. We added DEX into culture medium at different time. The expression of CD11c, CD86 and I-A(b) (mouse MHC class II molecule) was determined by flow cytometry. We determined the expression of NF-kappaB and its inhibitory protein I-kappaBalpha by electrophoretic mobility shift assay (EMSA) and Western blotting, respectively. The productions of interleukin (IL)-12p70 and IL-10 in cell culture supernatants were determined by enzyme-linked immunosorbent assay (ELISA).

RESULTSDEX impaired differentiation of DCs from murine bone marrow progenitors, and inhibited lipopolysaccharide (LPS) induced maturation of DCs. DEX significantly inhibited NF-kappaB expression of normal DCs, the higher the DEX concentration or the longer the DEX treatment time, the more obvious the effect. However, DEX had little effect on LPS-induced NF-kappaB activation, and partially impaired LPS-induced I-kappaBalpha degradation. DEX significantly decreased LPS induced IL-12p70 production by DCs. Interestingly, our results showed a synergistic effect between DEX and LPS on the production of IL-10 by DCs.

CONCLUSIONSDEX inhibits the differentiation and maturation of murine DCs involved in TLR4-I-kappaB-NF-kappaB pathway, and also indirectly impairs Th1 development and interferes with the Th1-Th2 balance through IL-12 and/or IL-10 secretion by DCs.

PURPOSEThis study aims to explore the biomechanical mechanism of lower limb injuries to the driver by establishing a finite element (FE) simulation model of collisions.

METHODSFirst a minibus FE model was integrated with a seat belt system. Then it was used to rebuild two collisions together with the total human model for safety (THUMS) provided by Toyota Motor Corporation: a rear-end collision between a minibus and a truck and a head-on collision of a minibus to a rigid wall. The impact velocities of both collisions were set at 56 km/h. The vehicle dynamic response, vehicle deceleration, and dashboard intrusion in the two collisions were compared.

RESULTSIn the minibus rear-end truck collision, the peak values of the von Mises equivalent stress at the tibia and the femur were 133 MPa and 126 MPa respectively; while in the minibus head-on rigid wall collision, the data were 139 MPa and 99 MPa. Compared with the minibus head-on rigid wall collision, the vehicle deceleration was smaller and the dashboard intrusion was larger in the minibus rear-end truck collision.

CONCLUSIONThe results illustrate that a longer dashboard incursion distance corresponds to a higher von Mises equivalent stress at the femur. The simulation results are consistent with the driver's autopsy report on lower limbs injuries. These findings verify that FE simulation method is reliable and useful to analyze the mechanisms of lower limb injuries to the driver in minibus frontal collisions.

OBJECTIVETo introduce the experience of treating nonunions of humeral fractures with interlocking intramedullary nailing.

METHODSTwelve patients with humeral nonunions were treated with interlocking intramedullary nailing. The time interval between trauma and surgery was 10.5 months on average. Open reduction with anterograde approach was performed. Axial compression was specially applied to the fracture site with humeral nail holder after insertion of distal locked screws. Iliac bone grafting was added.

RESULTSThe average follow-up period was 21 months (ranging 9-51 months). All patients achieved osseous union 5.8 months after treatment on average. Eleven patients had good functions of the shoulder joints and the upper extremities. No patient experienced any permanent neurological deficit. Refracture of the original ununited region occurred in one patient after removal of the internal fixator one year later, but union was achieved after closed re-intramedullary nailing fixation.

CONCLUSIONHumeral interlocking intramedullary nailing is an effective alternative treatment for humeral nonunion.

OBJECTIVECompared with Shengmai Capsule (生脉胶囊, SM), the study was conducted to evaluate the efficacy and safety of Xuefu Zhuyu Capsule (血府逐瘀胶囊, XFZY) on the symptoms and signs and health-related quality of life (HR-QOL) in the unstable angina (UA) patients with blood-stasis syndrome (BSS) after percutaneous coronary intervention (PCI).

METHODSA randomized, double-blinded, double-dummy, and placebo-controlled trial was applied. Ninety patients, diagnosed as UA and BSS after successful PCI, were enrolled and equally randomized into three groups, XFZY group, SM group, and placebo group, and administered with the corresponding medications respectively for four weeks. The clinical symptoms and signs (CSS), electrocardiography (ECG), and BSS scores were recorded and compared among groups during and after the treatment. Short-form 36 (SF-36) and Seattle Angina Questionnaire (SAQ) were applied to assess the HR-QOL in each group before and after the treatment. Safety indexes (blood routine and liver and kidney function tests) were also examined at the beginning and after the treatment.

RESULTSEighty-six patients completed the whole study. After the treatment, the total effective rates of the XFZY group in ameliorating CSS and ECG were 76.7% and 60.0%, respectively, which were obviously higher than those in SM (CSS: 53.3%; ECG: 36.7%) and the placebo (CSS: 43.3%; ECG: 30.0%) groups. After one week's treatment, BSS scores slightly decreased in each group, but no significant differences were found among three groups (P>0.05). After four weeks' treatment, BSS scores in the XFZY group decreased to a lower level compared with SM (P <0.05) and the placebo (P <0.01) groups. After the treatment, the efficacy of XFZY group in improving body pain (BP), general health (GH), vitality (VT), society functioning (SF), role emotional (RE), angina stability (AS), angina frequency (AF), and treatment satisfaction (TS) were better than those in the placebo group (P <0.05,P <0.01). Meanwhile, the dimensions of BP, GH, SF, AS, AF, and TS were better improved than those in the SM group P <0.05). No obvious adverse reaction was found during and after the treatment except one case in the XFZY group reporting of stomach discomfort.

CONCLUSIONSCompared with SM Capsule treatment, a short-term treatment with XFZY Capsule exhibits better efficacy on CSS and BSS scores, and HR-QOL in UA patients with BSS after PCI. However, its long-term efficacy and safety still needs further investigation.

OBJECTIVETo evaluate the efficacy of transcatheter arterial chemoembolization (TACE) on postoperative recurrence of hepatocellular carcinoma.

METHODSA total of consecutive 823 patients with hepatocellular carcinoma from October 1996 to September 2001 were included in this study. All patients underwent curative liver resection and 126 patients (15.3%) received TACE post operation. The effects of postoperative TACE on the recurrence of hepatocellular carcinoma with different pathological characteristics such as tumor size, tumor capsule, number of nodules, vascular invasion and surgical margin was analyzed.

RESULTSPostoperative TACE had not decreased the recurrence rate in patients with a tumor diameter less than 3 cm. Postoperative TACE increased the disease-free survival for patients with tumor diameter of 3 - 10 cm, positive in alpha fetoprotein (AFP), presented vascular invasion or patients with tumor diameter larger than 10 cm, positive in AFP, multi-nodular, presented vascular invasion, resection margin less than 1 cm.

CONCLUSIONSPostoperative TACE can decrease recurrence rate and prolong the survival of hepatocellular carcinoma patients with high risk factors for recurrence.
