Objective:To investigate the protective effect of dimethylsulfoxide(DMSO) on axon degeneration.(Methods: Cultured) rat superior cervical ganglia were treated with DMSO(100%,10 ?l) per well to disconnect axons from the cell bodies.SCGs in DMSO control group were treated with a mixture of DMSO(10 ?l) and medium (2 ml) per well;in positive control group were transfected with herpes simplex virus over-expressing Wld~S protein and the cell body was eliminated;and in blank control group were treated with 10 ?l PBS.The separated axons were fixed with 4% poly formaldehyde at 0,4,8,12 and 24 h after treatment with DMSO for immunostaining with specific antibody to microtubulin.Thus,the changes of axonal structure were investigated.The axonal protein was collected and the degeneration of neurofilament was detected by Western Blotting.Results: In DMSO disconnected group,the axonal morphology and structure showed no obvious change at 12 h post disconnection,but slight degeneration was observed at 24 h post disconnection.The degradation of microtubulin was obviously slowed down and their axonal structures maintained intact 12 h later.The neurofilament could be detected 12 h after disconnection.The above changes in disconnected group were similar to those in positive control group.No obvious protective effects on axonal degeneration were observed in blank and DMSO control groups.Conclusion: Local high concentration of DMSO can delay axonal degeneration,which indicates that DMSO can be used for adjuvant treatment of neurodegenerative diseases.

?Acute retinal necrosis syndrome ( ARN) is a serious eye disease, which caused by Herpes virus mostly, with unknown pathogenesis. Because of the aggressive progression, treatment of ARN is difficult, and the blindness rate is extremely high. Current treatment strategies are the combination of the drug therapy and the operative treatment. Drugs commonly used are antiviral drugs, glucocorticoids, and antiplatelet drugs, and the operative treatment includes laser photocoagulation and vitrectomy.

Objective:To evaluate the analgesic effect of low dose ropivacaine combined with fentanyl in patient controlled epidural analgesia (PCEA) and its influence on labor and safety of mothers and their newborns. Methods:One hundred and forty healthy nullipara at term were randomly assigned to epidural analgesia or control group. The analgesia group received PCEA when their labor stage reached active period in the first stage of labor.The PCEA mode was background infusion 6 ml/h, bonus 2 ml,lockout time 10 min/each infusion. The VAS, modified Bromage scale(MBS),duration and mode of labor, postpartum hemorrhage,Apgar scores of newborns were recorded. Results:Fifteen minutes after application of PCEA,98.58% of patients felt no pains(VAS 0.057?0.48),only 4.8% showed a mild motor block(MAS 0.07?0.31).By the 60 min,all patients could move the lower limbs freely (MAS 0). The analgesia group had a significantly shorter duration of active period in the first stage of labor than that of the control group, but a significant longer duration of the second stage. In addition, the oxytocin usage was significantly more frequently in analgesia group than those in placebo group.There was no difference between the two groups in the duration of third stage, postpartum hemorrhage, Apgar scores of newborns in 1 min and 5 min, rate of cesarean section and instrumental delivery.Conclusion:Epidural analgesia with low dose ropvicaine combined with fentanyl is safe and effective, which has no influence on mothers and their infants. It could shorten the active period of labor, but may increase oxytocin usage. The ratio of cesarean section and instrumental delivery was similar between the two groups. This kind of labor analgesia is beneficial and do no harm to mothers as well as newborns.

Objective To study the effects of total saponins of Chaenomeles speciosa on release of β-hexosaminidase from rat basophilic leukemia-2H3 ( RBL-2H3 ) mast cells. Methods After rat RBL-2H3 mast cells were prepared, total saponins of Chaenomeles speciosa and the RBL-2H3 mast cells were co-cultured.The toxic effects of total saponins of Chaenomeles speciosa on mast cells were detected by MTT method, β-hexosaminidase release rate was measured by fluorescence quantitative spectrophotometric method, and cell supernatants of tumor necrosis factor-α( TNF-α) release were detected by ELISA. Results After total saponins of Chaenomeles speciosa were co-cultured with RBL-2H3 mast cells with different antigen stimulation, β-hexosaminidase release rates and the levels of TNF-α of mast cells significantly decreased compared with the control group. Conclusion Total saponins of Chaenomeles speciosa inhibit the degranulation of RBL-2H3 mast cells in a dose dependent manner, which provids basis for studying mechanism of inhibiting allergic reactions.

Clinical teaching plays an important role in the education of medical graduate students.In the clinical teaching of the graduate students of burn and plastic surgery,we based it on clinical practice and guided the students in changing their modes of learning and thinking from examination-orientedness to problem solving,from simple vertical to clinical lateral thinking.We made sure that they all acquired innovative ideas and correct methods of clinical research by various academic activities,and cultivated their practical abilities and medical virtues by strict training and moral education.

Appropriate selection and measurement of lead biomarkers of exposure are critically important for health care management purposes, public health decision making, and primary prevention synthesis. Lead is one of the neurotoxicants that seems to be involved in the etiology of psychologies. Biomarkers are generally classified into three groups: biomarkers of exposure, effect, and susceptibility.The main body compartments that store lead are the blood, soft tissues, and bone; the half-life of lead in these tissues is measured in weeks for blood, months for soft tissues, and years for bone. Within the brain, lead-induced damage in the prefrontal cerebral cortex, hippocampus, and cerebellum can lead to a variety of neurological disorders, such as brain damage, mental retardation, behavioral problems, nerve damage, and possibly Alzheimer's disease, Parkinsons disease, and schizophrenia. This paper presents an overview of biomarkers of lead exposure and discusses the neurotoxic effects of lead with regard to children and adults.

Objective To study the impact of implanted thermoseeds of magnetic induction hyperthermia on radiation dose distribution. Methods To simulate irradiation, an anthropomorphic phantom and three-dimensional treatment planning system were used. The impact of thermoseeds on radiation dose distribution was evaluated. Results The change of absorbed dose caused by the implantated thermoseeds was less than 1.5%. Conclusions The impact of implanted thermoseeds on radiation dose distribution is small and comes up to the requirements that the total target dose uncertainty must be less than 5%. Therefore, the impact of thermoseeds on the absorbed dose in tissue can be ignored in clinical practice.
