Objective To summarize the clinical experience of fat granule injection for auto-trans-plantation in the treatment of concave temporal area. Methods The fat granule was extracted with injec-tor and injected into temporal area after washing and purging, but it might be necessany for patient to be injected extra 20 % fat autograft due to his absorptive effect. Results Satisfactory results were obtained in all patients. Transplantation was carried out one time in 139 cases, two times in 9 cases, and three times in 4 cases. 6 - 28 ml fat granule was injected in one site at each time. Conclusion Fat granule injec-tion for auto-transplantation is a safe and ideal method to treat concave temporal area.

Bone marrow mesenchymal stem cells (BMSCs) are a kind of pluripotent stem cells derived from bone marrows, which can not only support hematopoiesis, but also have capabilities of multidifferentiation, high-proliferation and self-renewing. They have become one of hotspots in stem cell studies. Studies on in vitro intervention with BMSCs with TCMs have made remarkable progress in recent years. According to the findings, some traditional Chinese medicines can promote proliferation of BMSCs, some can inhibit the apoptosis of BMSCs, while others can induce BMSCs to differentiate into multiple cell types, such as osteoblast. Furthermore, some studies also involved relevant action mechanisms. The authors summarized the advance in relevant studies by reference to relevant literatures of this field.

The intracellular hepatitis B surface antigen (HBsAg) content per cell was increased by 7.2-fold in the culture with 1.5% dimethyl sulfoxide (DMSO) compared with that in the control without DMSO, while the extracellular HBsAg production and specific productivity were only improved by 70% and 3.2-fold, respectively. Electron microscope has been employed to reveal large dilated structures within recombinant CHO cells in the presence DMSO. The dilated structures have a distribution within whole cytoplasm, and some dilated areas were engulfed in the nucleus. These large, dilated structures were not observed in the control. Immunogold labeling was used to discover the accumulated HBsAg was localized within these dilated areas, and some HBsAg-specific labels were detected in the nucleus membrane, owing to the encroachment of the dilated areas upon nucleus. The result could help to reveal the mechanism of intracellular HBsAg accumulation in the presence of DMSO.

OBJECTIVE: To analyze the features of death cases in the urban rail traffic accidents in order to prevent the similar accidents in the future and to provide reference for forensic expertise. METHODS: Eighteen death cases in urban rail traffic accidents between 2005 to 2008 in Shanghai were collected. The forensic characteristics were summarized in aspects of the nature of cases, the injury mechanism and characteristics, etc. RESULTS: There were total 18 cases with 14 suicide and 4 accidental incidents, aged from 21 to 55 years. Of those dead, 14 died of craniocerebral injury and 4 died of traumatic shock. The injury mechanism included hit, fall and rolling. CONCLUSION The injury in urban rail traffic accidents have their own characteristics, mainly due to suicide, and partly due to accidental incident, and most of these cases are probably preventable.
