BACKGROUND: In vivo experiments have confirmed that fibroblast growth factor can effectively protect gentamicin-induced renal tubular epithelial cell injury, but the effect on the in vitro cultured cells is still rare. OBJECTIVE: To explore the mechanisms of basic fibroblast growth factor (bFGF) at different concentrations on preventing nephrotoxity mediated by genamicin on the primarily cultivated renal tubular epithelial cell models. METHODS: By use of enzyme and mesh screening, renal tubular epithelial cells were isolated from Kunming mice and purified, adjusting the cell concentration of 1×10~8/L, then cell suspension was moved to a 96-well culture plate and divided into different groups for culture: blank control group: normal culture; gentamicin group: 10, 30, 50 μL/hola (ie, 400, 1 200, 2 000 U/holes)arerecorded as G1, G2, G3; bFGF group: 20, 50, 80 μL/hole (ie, 90,225, 360 ng/hole) are recorded as B1, B2, B3; gentamicin plus bFGF intervention group: after adding bFGF 12 hours, then added gentamicin 12 hours, assigned into 9 dose subgroups, namely, G1B1, G1B2, G1B3, G2B1, G2B2, G2B3, G3B1, G3B2, G3B3, each subgroup contained four-hole complex. Cell morphology and quantity was observed. RESULTS AND CONCLUSION: Gentamicin showed a dose-dependent effect on the renal tubular epithelial cell injury, epithelial cells in the medium and high concentration groups exhibited shrinkage, rounded, swelling, poor adhesion, severely damaged cytoplasm and structural disorder. In the low concentration group, the number change of cells was not obvious, and fibroblasts began to appear; In the bFGF groups, cells were full, exhibited strong refraction, the cell number increased significantly, these manifestations were significant in 50 μL/hole concentration, and there was no significant difference compared with 80 μL/hore concentration; in case of gentamicin plus bFGF intervention, cells with low concentrations of gentamicin had no obvious damage to cells, which increased, the damaged cells collapse was reduced in the group of low concentration of gentamicin, cell shrinkage and poor adhesion were slightly relieved, high concentrations of bFGF intervention could yield to good cell morphology, but high concentrations of gentamicin caused cell swelling and necrosis of injury, which could not be improved by any concentrations of bFGF intervention. 50 μL/hole bFGF has antagonistic effect on the nephrotoxicity mediated by medium and low concentrations of gentamicin, but has no protection on high concentration of gentamicin-induced nephrotoxicity.

To clarify the effect of the sympathetic nerves on the body's physiopathological changes and acupuncture effect by the alphal-AR mediation in the past 30 years.The paper has referred to the database of CNKI and Pubmed,and systematically reviewed the publications in the past 30 years about the research of the alphal-AR mediation of the sympathetic nerves to the body's physiological andpathological changes and acupuncture effect.Alphal-AR not only mediated the sympathetic nerves on the inotropic change of the heart,and the contraction of the vascular smooth muscles,bladder sphincter,and uterine smooth muscles and other physiological effect,but also mediated cardiac arrhythmia,myocardial hypertrophy and other pathological process.In addition,Alphal-AR also mediated the acupuncture signal transmission,and acupuncture was able to adjust the sympathetic nervous tension.The body's physiopathological changes are closely related to alpha1-AR and subtype alteration.The in-depth study of alphal-AR helps to explain physiopathological mechanism of the body,as well as provide theoretical basis and the corresponding pharmacological models for better selective drugs.Studying Alpha1-AR on meridians contributes to the discovery of meridian essence and the substantial basis of acupuncture effects.

OBJECTIVETo explore the change pattern of hypothalamic-pituitary-adrenal (HPA) axis and related neurotransmitters under simulated weightlessness.

METHODSA total of 40 clean-grade male Wistar rats were randomly divided into a normal group, a tail-suspension group, an electroacupuncture (EA) at Neiguan (PC 6) group, an EA at Sanyinjiao (SP 6) group, 10 rats in each group. Rats in the tail-suspension group, EA at "Neiguan" (PC 6) group and EA at "Sanyinjiao" (SP 6) group were treated with tail suspension to simulate weightlessness effect. Rats in the normal group were treated with normal diet. Rats in the tail-suspension group were treated with tail suspension for 28 d. During the time of tail suspension, rats in the EA at "Neiguan" (PC 6) group were treated with EA at "Neiguan" (PC 6), 30 min per treatment, once every two days for 14 treatments, while rats in the EA at "Sanyinjiao" (SP 6) group were treated with EA at "Sanyinjiao" (SP 6), 30 min per treatment, once every two days for 14 treatments. Samples were all collected after 4 weeks. The contents of corticotropin releasing hormone (CRH) , adrenocorticotropic hormone (ACTH), corticosterone (CORT) in as well as 5-hydroxy tryptamine (5-HT), dopamine (DA), norepinephrine (NE) were measured by using radioimmunoassay.

RESULTSCompared with the normal group, in the tail-suspension group the content of ACTH in pituitary was significantly decreased (P< 0.05), and the content of 5-HT in hypothalamus was significantly decreased (P < 0.01); the content of CRH and 5-HT in hypothalamus was significantly decreased (P < 0.01, P < 0.05) in the EA at "Neiguan" (PC 6) group; the content of CRH and 5-HT in hypothalamus was significantly decreased (P < 0.01), and the content of CORT in serum was significantly decreased (P < 0.05) in the EA at "Sanyinjiao" (SP 6) group. Compared with the tail-suspension group, the content of ACTH in hypothalamus was significantly decreased (P< 0.05) in the EA at "Neiguan" (PC 6) group; the content of CRH, ACTH and CORT was significantly decreased (P < 0.01, P < 0.05) in the EA at "Sanyinjiao" (SP 6) group. Compared with the EA at "Neiguan" (PC 6) group, the content of CORT was decreased (P < 0.05) in the EA at "Sanyinjiao" (SP 6) group.

CONCLUSIONEA can regulate the content of 5-HT in hypothalamus in tail-suspension rats, inhibit the hyperactivity of the HPA axis, in which EA at "Sanyinjiao" (SP 6) had more significant effects than "Neiguan" (PC 6), but no obvious effects on NE and DA were observed.
