ABSTRACT
AIM: To study the role of post-hemorrhagic shock mesenteric lymph (PHSML) drainage on the balance of angiotensin-converting enzyme ( ACE) and ACE2 in the kidney.METHODS:A hemorrhagic shock model was established and then fluid resuscitation was performed to the animals in shock and shock+drainage groups, and the PHMSL was drained in shock+drainage group after fluid resuscitation.After 6 h of resuscitation, the mRNA expression of ACE, ACE2, angiotensin II (Ang II) type 1 receptor (AT1R) and Mas-related G-protein-coupled receptor (MasR), and the levels of Ang II and Ang (1-7) in the renal tissues were observed.RESULTS:Hemorrhagic shock increased the levels of ACE mRNA, AT1R mRNA and Ang II, and decreased the levels of ACE2 mRNA, MasR mRNA and Ang(1-7) in the kid-ney.PHSML drainage abolished the effect of hemorrhagic shock on ACE2 and AT1R mRNA expression.Meanwhile, PHSML drainage reduced the hemorrhagic shock-induced increases in the ratios of ACE/ACE2, Ang II/Ang(1-7) and AT1R/MasR.CONCLUSION:The PHSML drainage restores the balance of ACE/ACE2, which is beneficial to alleviate acute kidney injury following hemorrhagic shock in the mice.
ABSTRACT
Objective To summarize the operative experience of ventricular septal defect(VSD) with severe pulmonary hypertension(PH).Methods 37 patients with VSD complicated with severe PH,who underwent surgical repair were treated combinatively in perioperative period including resting,oxygen inhalation,and administration of captoprill and prostaglandin E 1(PGE 1).All of the patients were operated by cardiopulmonary bypass with moderate hypothermia.Arterial oxygen saturation(SaO 2),pulmonary arterial pressure and cardiac function were observed before and after operation,and progression of cardiac function and mortality were followed-up after discharged.Results 2 patients died of low cardiac output syndrome(LCOS) and one patient died of respiratory failure,and the operative mortality was 8 1%.one patient was diad after 8 months and the cardiac function of 33 patients markedly improved.Conclusions Reasonable treatment in perioperative period and holding the indications for the operation strictly are the keys to decrease the mortality of the operation,and SaO 2 could be a simple measurement to identify the indication of operation and the prognosis of the patient with VSD complicated with severe PH.
ABSTRACT
We have enhanced the quality and efficiency of nursing through the management of the work by means of standard quantized integration. The measures include formulation in the first place of various quantized standards and detailed assessment rules and then the working out of assessment methods. The adoption of these measures in our hospital has led to the improvement of its managerial expertise, the enhancement of its nursing personnels quality and competition awareness, the stimulation of its staffs enthusiasm, and the strengthening of its nursing work in teaching and research management. As a result, nursing in the hospital has become more scientific and efficient.
ABSTRACT
OBJECTIVE To discuss the management method of hospital medical waste in nursing activity,prevent from the pollutant proliferation,and avoid the second exposure.METHODS Reinforced the management of the medical waste,established the management network of medical waste,and made the training of all staffs,we drew up a series of effective measures according to the law and regulation.RESULTS Various plan and measure were done, nursing personnel were fully aware of the importance of the environmental protection.(medical) waste(management) was much better than before.The infection which related to the medical waste was not occurred.(CONCLUSIONS) Doing well management of the medical waste is depending on some conditions,which are as(follows:)(1)the leaders pay more attention to;(2)strengthen the training of all staffs;and(3)the management system is sound.
