ABSTRACT
Objective To study the effect of Shenfukang Ⅱ on kidney function and TGF-β1/Smads signal pathway with 5/6 nephrectomy model in rats. Methods Thirty SD rats were randomly divided into the sham operation group, model group and Shenfukang group according to a random number table. We used 5/6 nephrectomy to prepare animal models. The rats were given Shenfukang Ⅱ particles 450 mg/(kg?d) gavage, the others group were given equal volume of saline gavage, once a day, continuous 21 days. The rats were given gavage at the 9 th week after operation. The changes of renal function index BUN, SCR and UA of rats in each group were detected 21 days after administration. The expression of TGF-β1, TGFβR1, Smad7, pSmad2, pSmad3 in renal tissues were detected by immunohistochemistry. The Smad7, pSmad2 and pSmad3 detected the expression of in renal tissues by Western Blot. Results Compared with the model group, the content of BUN (15.03 ± 2.19 mmol/L vs. 24.30 ± 2.82 mmol/L), SCR (74.22 ± 7.36 μmol/L vs. 93.61 ± 14.73 μmol/L) in Shenfukang group significantly decreased (P<0.05). The expression of TGF-β1, TGFβR1, pSmad2 and pSmad3 significantly decreased in kidney tissue, while the expression of Smad7 significantly increased in kidney tissue. The expression of p-smad2 (0.47 ± 0.03 vs. 0.64 ± 0.04) and p-smad3 (0.43 ± 0.04 vs. 0.55 ± 0.02) significantly decreased (P<0.05), and the expression of Smad7 (0.54 ± 0.03 vs. 0.39 ± 0.02) significantly increased (P<0.05). Conclusions Shenfukang Ⅱ have improved on kidney function with 5/6 nephrectomy model rats. The study revealed that Shenfukang II may play an anti-fibrotic effect on regulating TGF-β1/Smads signaling pathway with 5/6 nephrectomies model.
ABSTRACT
Objective:To explore the effects of CICARE communication model in emergency nursing .Meth-ods:The CICARE communication model was applied from the beginning of administration to rescue and transfer processes .The nurses were required to apply the CICARE communication skill to the whole nursing process through training , scenario simulation , role playing , practice and assessment .Results:The communication ability of nurses and satisfaction of patients improved significantly .Doctor -patient disputes decreased .Conclusions: CICARE communication model , as an effective way of communication plays a important role in promoting the comprehensive quality of nurses and the nursing quality .
ABSTRACT
Objective We aimed to assess effectiveness of Risk Score Scale (RSS) for aortic Dissection (AD) in early triage stage.Methods A total of 251 patients with acute chest or back pain complaints were allocated by triage nurses according to the pre-established RSS from 2011 to 2013.87 cases were assessed to have 5 points or more,and 80 cases were assessed to have 6 points or more from 95 patients diagnosed as aortic dissection (the diagnosed group) by CT angiography and magnetic resonance imaging while excluded 156 cases of control after discharge (control group).The general conditions,distribution of aortic dissection risk factors,aortic dissection risk score,sensitivity and specificity of RSS between two groups were compared.The misdiagnosis rate,missed diagnosis rate,RSS triage sensitivity and specificity and OR value were compared between RSS ≥5 points and RSS ≥6 points.Results There was significant differences in abrupt onset of severe pain intensity,ripping or tearing pain,pulse deficit or systolic blood pressure differential between extremities [upper extremity≥20 mmHg (1 mmHg=0.133 kPa) or lower extremity≥ 10 mmHg],x2 value was 62.6,94.2 and 20.2.RSS≥5 points had high sensitivity and specificity,lower missed diagnosis rate and high OR value for triage application.Conclusion RSS≥5 points could serve as a reliable evidence for early triage of aortic dissection.
ABSTRACT
Objective:The purpose is to observe the change of the number of apoptosis cell in the reversible-ischemia rat brain after the intraperitoneal injection of rhANG. Methods:With the use of a reversible(middle cerebral artery occlusion (MCAO))m odel in rats,apoptosis cells were assessed by(terminal deoxynucleotedyl transferase(TdT))-mediated dUTP-biotin nick end labe ling(TUNEL) histochemical methods in sham,brain ischemia control and rhANG intraperitoneal injection groups.Results:There was no significant difference in the number of the apoptosis cell in the penumbra zone in the ischemic brain between the rhANG intraperitoneal injection group and the brain ischemia control group.The number of apoptosis cell in the ischemic lateral brain was increased significantly compared with the non-ischemia lateral in the brain ischemia control group and the rhANG intraperitoneal injection group. Conclusion:There was no significant difference in the number of the apoptosis cell in the penu mbra zone in the ischemic rat brain after the intraperitoneal injection of rhANG(15ng/100g)compared with the control group.
