Methods VSMCs were cultured from aorta of WKY rats.The hypertensive patients" serum was purified by am- monium sulfate precipitation and affinity chromatography.The effect on VSMC proliferation this autoantilody was determined by BrdU incorporation.Total protein and the expression of phosphorylation JAK-STAT were assessed by Western blotting.Results AT_1RAb caused a significant increase in BrdU incorporation similar to Ang Ⅱ during 0-24 h reaching peak value at 12 h.The A value of in 450 nm was higher in AT_1RAb group (0.236?0.012)than AG490+AT_1RAb group(0.176?0.009),Losartan+AT_1RAb groups(0.119?0.006) and Serum Free group(0.127?0.006)(P

OBJECTIVETo analyze the literature on power frequency electric field testing data and to propose views and suggestions for current testing.

METHODSThe literature on power frequency electric field testing data published in the previous years was searched to identify 306 articles involving 193 valid testing data. Mann-Whitney test and Wilcoxon W test were used for analyzing the testing data.

RESULTSThe classification of data was carried out according to one quarter of occupational exposure limit (1.25 kV/m), one half of the exposure limit (2.5 kV/m), and the exposure limit (5 kV/m). The structure of testing data showed a significant difference between the non-power facility group and the power facility group (P<0.05).

CONCLUSIONAs occupational hazard factors, the radiation exposure from power frequency electric field is extensive. However, the power frequency electric field testing data in actual workplaces except high-voltage power facilities are far less than the occupational exposure limit with little harmfulness. There is a phenomenon of excessive testing at present.

Objective To investigate the clinical effect of early rehabilitation treatment on patients with severe traumatic brain injury (sTBI).Methods Forty sTBI patients were divided into treatment group (n =20) and control group (n =20) according to the random number table.Conventional treatment was performed on all patients including dehydration to decrease intracranial pressure,hemorrhage control,neurotrophic treatment,antiinflammation therapy,and gastric acid control.In addition to these interventions,patients in treatment group received hyperbaric oxygen treatment,median nerve stimulation,fastigial nucleus stimulation,and bedside motor therapy in the early period.Intracranial pressure and partial pressure of brain tissue oxygen (PbtO2) were continuously monitored during the process of treatment.GCS was measured before and 15 days after treatment and single-photon emission computed tomography (SPE-CT) was used to evaluate cerebral perfusion.Results There was no statistical difference between the two groups with respect to GCS in advance of treatment (P ＞ 0.05),but GCS differed between treatment group and control group after treatment [(10.18 ± 3.75) points vs (8.33 ±2.36) points,P ＜0.05],with substantial improvement in treatment group.Significantly improved cerebral perfusion was seen in treatment group.On day 5 after treatment,intracranial pressure in treatment group lowered significantly compared with that in control group (P ＜ 0.05).On day 6 after treatment,PbtO2 was significantly higher in treatment group than in control group (P ＜ 0.05).Conclusion Early rehabilitation treatment leads to improved outcome and acts a positive effect on nerve function recovery.
