Objective To study the method and nursing measurements of the detection of portal venous pressure. Method The implantable drug delivery system was performed during the operation in 31 patients with liver cancer. The direct dynamic observation was performed by using the system and the corresponding nursing measurement was given. Result The measurement of portal venous pressure was successful performed 251 times in 31 cases with liver cancer and no complications were taken place. Conclusions The dynamic observation of portal venous of pressure by using the implantable drug delivery system was simple. Safety and could be repeated and could easily be receipted by the cases, the nurses skilled measured the key points of nursing and actively prevented the complications was taken implant role in increasing the rate of success of detection .

AIM: To study the suppressive effect of c hu ankezhi (CKZ) injection, a Chinese medicine, on murine allergic contact dermatit is (type IV hypersensitivity). METHODS: Mice were divided into 6 groups according to different medicine treatments: CKZ high, middle, low dose ( CKZⅠ,Ⅱ,Ⅲ) groups, dexamethasone(DEX), benadryl and saline groups. Murine alle rgic contact dermatitis was induced by intraperitoneal injection of 2, 4-dinitro fluorobenzene. Different medicines were administrated at 2 h before sensitizatio n on day 0 and day 1, day 2, 2 h before elicitation and 6 h after on day 5. The six experimental groups were compared according to left ear thickness difference (S1), left ear weight difference (S2), body weight difference (S3) and dermal i nflammatory infiltration cell number. RESULTS: Compared with saline group, the left ear swelling and d ermal inflammatory infiltration cell number were significantly reduced in CKZⅠ, Ⅱ,Ⅲ and DEX groups (P

Objective To investigate the diagnostic value of susceptibility-weighted imaging (SWI)in the application of mild traumatic brain injury.Methods The clinical data of 78 patients with mild traumatic brain injury were analyzed retrospectively.All patients received SWI and conventional MRI examination (T1WI, T2WI and FLAIR), and the number of intracerebral hemorrhagic lesions was compared between SWI and conventional MRI.Results The number of intracerebral hemorrhagic lesions of SWI examination was significantly much than that of conventional MRI examination: 39.74% (31/78)vs.21.79%(17/78),and there was statistical difference(χ2=5.898,P=0.015).SWI depicted 156 hemorrhagic lesions,and conventional MRI(T1WI,T2WI and FLAIR)depicted 16,26 and 37 hemorrhagic lesions.SWI depicted a significantly higher number of hemorrhagic lesions than conventional MRI,and there was statistical difference(Z=-4.563,-4.476 and-4.478;P<0.01).The Glasgow coma score on admission in patients with hemorrhagic lesions of SWI examination was significantly lower than that in patients without hemorrhagic lesions of SWI examination:(14.23 ± 0.80)scores vs.(14.84 ± 0.48)scores, and there was statistical difference (Z =- 3.956, P<0.01).The number of intracerebral hemorrhagic lesions in SWI examination was negative correlation with Glasgow coma score on admission(rs=-0.471, P = 0.008).Conclusions SWI has higher sensitivity in detecting intracerebral hemorrhages compared with conventional MRI.It can objectively and accurately evaluate the severity of patients with mild traumatic brain injury.
