Objective:To evaluate the acute oral toxicity , skin irritation and skin allergy of Thuja essential oil ( TEO) , and pro-vide experimental basis for the clinical use of TEO .Methods:The acute oral toxicity was measured by Horn ’ s assay .Totally 40 KM mice were divided into four groups and intragastrically administered with TEO at different dose of 21.50, 10.00, 4.64 and 2.15 g · kg-1 .After the 14-day observation, the death number and toxic manifestations were recorded and observed , and LD50 was calculated by checking the Horn's form of LD50 .The skin irritation test was performed on healthy adult white rabbits .Totally 9 rabbits were divid-ed into 3 groups randomly , and TEO at the concentration of 100%, 50%and 25%was painted on the skin of the rabbits .Edible vege-table oil was used as the negative control .The erythema and edema of the treated skin were evaluated and scored .Delayed skin hyper-sensitivity reaction was used to investigate the allergy of TEO .Totally 30 white guinea pigs were randomly divided into 3 groups:TEO group, the negative control (edible vegetable oil) and the positive group (1%2, 4-dinitrochlorobenzene).After the intracutaneous in-duction stage and local induction stage , TEO was used to activate the hypersensitive reaction .The skin response was observed and scored after the 24-hour and 48-hour activation.Results:The mice in 21.50 g · kg-1 TEO treatment group were all dead , while only a part of the mice in 10.00 and 4.64 g · kg-1 TEO treatment groups were dead , and no mice died in 2.15 g · kg-1 TEO treatment group.According to the Horn's form of LD50 , LD50 of TEO was 9.26 g · kg -1 for male mice and 7.94 g · kg -1 for female mice.The results of skin irritation test indicated the strong irritation effects of TEO .However , the irritation of TEO was reduced after the dilution , and 25%TEO showed no irritation to the skin of rabbits .The results of delayed skin hypersensitivity reaction showed obvious erythema and edema induced by 2, 4-dinitrochlorobenzene , while no obvious erythema and edema were found in TEO treated guinea pigs , indi-cating non-allergic effect of TEO .Conclusion:TEO has strong skin irritation in rabbits , while no obvious oral toxicity in mice and skin allergy in guinea pigs .

Objective To explore the value of bedside ultrasound used by ICU doctor in the rapid diagnosis of traumatic abdominal,and to evaluate the advantage of bedside ultrasound in the treatment decision.Methods 60 patients with traumatic abdominal blood in our hospital admitted to the ICU were selected.All patients were checked through bedside ultrasonography by physicians with professional training of ICU,bedside ultrasound and abdominal CT and abdominal flat piece of traumatic hematocelia,and compared the diagnosis of the time of the bedside ultrasound,abdominal CT and abdominal X -ray and ultrasound physician ultrasound examination.Results The difference of abdominal blood detection rate between bedside ultrasonography and abdominal computed tomo-graphy (CT)had no statistical significance (P >0.05);bedside ultrasonography of abdominal blood detection rate was higher than plain film of the abdomen,the difference was statistically significant (χ2 =73.346,P <0.01);bed-side ultrasound received a preliminary diagnosis of time -consuming (4.37 ±2.1)min was significantly lower than that of the examination of ultrasound physicians (13.86 ±5.6)min,abdominal CT (22.13 ±6.9)min and abdominal plain film (28.19 ±7.32)min,the differences were statistically significant (t =3.947,14.607,21.139,26.338,all P <0.01 ).Conclusion By the professional training of ICU physicians for bedside ultrasound traumatic blood abdominal patients can make a more accurate diagnosis,time -shorten,more accord with the requirement of treating critically ill patients in ICU,which has important clinical value for trauma abdominal blood in early rapid diagnosis and treatment.

Objective To analyse the possible risk factors associated with the progression of vitiligo.Methods A questionnaire survey was carried out to collect the clinical data on 1088 patients with vitiligo.The relationship between possible inducements to the progression of vitiligo and lesion area was statistically analyzed in patients with the same clinical course of vitiligo. Paired t test was performed to compare the mean area index of involvement between patients with inducements and those without Results A significant difference was observed in the mean area index of involvement between patients with isomorphic response and those without (t = 6.770, P ＜ 0.01 ) as well as between patients negatively affected by psychiatric factors and those unaffected (t = 6.704, P ＜ 0.01 ), but not between patients with family history and those without (t = 1.499,P ＞ 0.05). Conclusion A rapid progression of vitiligo is more likely to be observed in patients negatively affected by psychiatric factors and patients with isomorphic response.

Objective To investigate the effects of different surface treatments on shear bond strength between diatomite-based dental ceramic and IPS e.max veneering ceramic.Methods Diatomite-based dental ceramic was randomly divided into acid-etched group,sandblasting group and untreated group,and then sintered with IPS e.max veneering ceramic,respectively.Shear bond strength were detected,and the interface microstructures and elemental distribution were observed by scanning electron microscope-energy dispersive spectrometer (SEM-EDS).Results Shear bond strength of acid-etched group was significantly higher than that of untreated group (P＜0.01).SEM observation results showed that the interface of acid-etched group bonded closely.There was no statistical difference of the shear bond strength between the sandblasting group and untreated group (P＞0.05).Conclusions Acid-etched treatment can significantly enhance the bond strength of diatomite-based dental ceramic and IPS e.max veneering ceramic.
