A growing body of evidence has indicated the important role of autophagy receptors in directing ubiquitinated or non-ubiquitinated cargos towards autophagy. Autophagy receptors bind to LC3 (microtubule-associated protein 1 light chain 3) on phagophore and autophagosome membranes, and recognize signals on cargoes in the delivery system of autophagy. However, the diverse domains in the receptor structures determine that their roles would never be limited to autophagy. Up to date, increasing numbers of the receptor proteins have been demonstrated to serve as a molecular link or switch participating in autophagic degradation, apoptosis or cell survival signals. Here, we highlight the non-autophagic roles of these receptor proteins to draw attention to this growing research topic.

In the criminal cases of driving under the influence (DUI), DNA evidence can be collected from the deployed airbag of the motor vehicle and submitted to the crime lab for touch DNA analysis. The evidence can be acquired when the skin cells are observed on the surface of the airbag in a traffic accident. However, the low quantity or quality of the evidence collected from a crime scene prevents further identification analysis in many cases. In the current study, we reported a case of identifying touch DNA extraction from the shed skin cells from the deployed airbag of a motor vehicle. We managed to collect DNA evidence from the shed skin cells in an airbag using a proper approach of collection and extraction. The 5.87 ng of extracted DNA was sufficient for genotyping and forensic identification, which helped to identify the driver of the car in collision with a pier in the street. In DUI cases and other traffic accidents, therefore, the amount of touch DNA extracted from the deployed airbag can be sufficient for DNA marker genotyping and further analysis.

OBJECTIVETo compare the difference in the efficacy on low back pain of cold-damp pattern between electric-thermal Bian-stone therapy and moxibustion box therapy.

METHODSForty-one cases of low back pain of cold-damp pattern were randomized into an electric-thermal Bian-stone therapy group (group A, 26 cases) and a box moxibustion therapy group (group B, 15 cases). In the group A, the electric-thermal Bian-stone was placed over Shenshu (BL 23) and Weizhong (BL 40). The temperature of stone was adjusted in accordance with patient's comfort. In the group B, moxibustion box was used over Shenshu (BL 23) and Weizhong (BL 40). The treatment was given once every day or every two days. Ten treatments made one session. The symptom and physical signs score of low back pain and the score of cold-damp syndrome were observed before and after treatment in the patients.

RESULTSThe symptom and physical signs score of low back pain and the score of cold-damp syndrome were all improved in the two groups (all P < 0.01). The changing rate of symptom and physical signs and syndrome were (37.04 +/- 32.68)% and (22.85 +/- 29.95)% in the group A, and were (47.29 +/- 22.08)% and (23.89 +/- 22.53)% in the group B, respectively, without significant difference in comparison between the two groups (all P > 0.05).

CONCLUSIONThe efficacy on low back pain of cold-damp pattern treated with the electric-thermal Bian-stone therapy is similar to that of moxibustion box therapy. This therapy is characterized as more convenient, safer operation and less pollution.

· AIM :To investigate the role of pericytes in growth of retinal microvascular endothelial cells with a co-culture system in order to understand some mechanism of angiogenesis in hypoxia induced retinal neovascular disorders.(RMECs) were isolated by a modified protocol using CD31 coated Dynabeads, and identified by immunocytochemical staining with anti-Factor Ⅷ and CD31 antibodies. Rat retinal pericytes were isolated and characterized by immunofluorescent staining with PDGFR-β; and desmin antibodies. Pericytes and RMECs were cultured in a contact co-culture system both under normoxia and hypoxia by Millicell chamber. RMECs proliferation was evaluated by MTT and cell cycle assay with flow cytometry. RT-PCR was used to detect the alteration of KDR/Flk-1 mRNA level in RMECs under normoxia or hypoxia in the co-culture system.harvested with the modified isolating method. The two cell types were identified by positive Factor Ⅷ, CD31 and PDGFR-β, desmin cytochemical staining respectively.RMECs proliferated significantly under hypoxia from 3 to 9d with a maximal rate on day 6 (24.9%, P ＜ 0.01) by MTT. In the co-culture system, the proliferation of RMECs was inhibited by pericytes. After 6d exposure to hypoxia,the fraction of S-phase RMECs number was greatly increased by 43.9% (P ＜ 0.01). In the co-culture system,RMECs proliferation was inhibited by pericytes through decreasing the fraction of S-phase cell number both under normoxia (3.6%, P＜0.05) and under hypoxia (15.1%,P＜0.01). KDR/Flk-1 mRNA level in single cultured RMECs was shown to increase approximately 1.3-fold when exposed to hypoxia. Compared with single cultured RMECs, co-culture with pericytes could decrease KDR/Flk-1 mRNA by 45.1% (P＜0.05) and 27.7% (P ＜ 0.05) under normoxia and hypoxia condition respectively.pericytes could inhibit proliferation of RMECs under both normoxia and hypoxia. The inhibition effects of pericytes maybe, at least in part, due to downregulation of KDR/Flk-1 of RMECs. These findings confirm that pericytes could be a potential inhibitor in the pathogenesis of retinal neovascularization.
