Chinese Journal of Anesthesiology 1994;0(01):-
Objective: To study the effect of low-dose dopamine on splanchnic DO_2/VO_2.in rabbit SMAO shock Method:Twenty rabbits were randomly devided into two groups:group A with dopamine,group B as control group. In group A dopamlne was infused at a rate of 5?g?kg~(-1)?min~(-1). SMAO shock model was induced in both groups. Cardiac output index(Cl),portal venous blood flow index (QpvI),mean arterial pressure (MAP),arterial. artiaI and portal venous blood gas analysis.arterial and portal venous serum lactate concentrations(ALT,PLT), total oxygen delivery/oxygen consumption (TDO_2/TVO_2), splanchnic oxygen delivery/oxygen consumption (SDO_2/SVO_2). oxygen extraction ratio(O_2ER) were measured respectively. Result: QpvI, SDO_2,SVO_2 were higher in group A than those of group B (P0.05). CI,MAP, TDO_2/TVO_2 decreased. TO_2ER and SO_2ER increased in both of groups during shock, but without significant differences between both groups. Conclusion: Low-dose dopamine has beneficial effects by increasing portal venous blood perfusion and improving splanchnic oxygenation during SMAO shock in rabbits. but no effects on systemic oxygenation of shock.

Methods To take geriatric nursing belonged to MeSH thesaurus as key words, related literatures from 2006 to 2016 in Web of Science core collection were searched, then clustering analysis were adopted to analyze highly cited papers. Results Totally 2148 pieces of literatures related to geriatric nursing, there were 80079 pieces of quotations. The contents involved inappropriate medication use and falls in geriatric nursing risk management, functional decline, delirium and chronic cognitive impairment of the elderly, distinguishing between the basic theory of geriatric diseases, tools and practice of geriatric nursing assessment. Conclusions The current research hotspots on geriatric nursing includes: the risk management of geriatric nursing, prevention and control of geriatric syndrome, systematic study on geriatric nursing assessment.

Objective To investigate the signal pathways involved in the effects of thyroid stimulating antibody(TSAb)on the secretory function of cultured thyrocytes.Methods (1)With the method of enzyme-linked immunosorbent assay (ELISA),the PKA and PKC activities were observed.(2)Inhibitors or activators of protein kinases (PKA and PKC) were used to activate or block the signal pathways and the secretion of T3 measured by radioimmunoassay.Results (1)TSAb activated both PKA and PKC in thyrocytes in a dose-,time-dependent manner(.P.

Objective To investigate diagnosis and surgical treatment of primary retroperitoneal tumor. Methods The clinical data of 26 cases with primary retroperitoneal tumor was retrospectively analyzed.Results 13 cases with benign tumor and 10 cases with malignant tumor underwent total resection, only 3 cases with malignant tumor underwent local resection. One case with malignant tumor recurred within 2 weeks and death after operation about 28 days.Conclusions IVP,B-ultrasonography, CT and MR diagnosis of primary retroperitoneal tumor is very important for preparation of preoperation and estimation of target organ. Repeatedly operation can improve cure rate.

Objective To study the perioperation management and surgical therapy of Graves' disease accompanied with severe thyroid gland enlargement. Methods 32 cases of Graves' disease with severe thyroid gland enlargement were included in our study and their symptom control, perioperation management, surgical therapy and postoperative complication treatment were analysed retrospectively. Results There was no surgical death among the 32 patients. The incidence of postoperative complications was 21.9%. And among them, 2 cases had respiratory tract obstruction, 2 cases temporary hypocalcemia and 3 cases mild hypothyroid. ConclusionFor Graves' disease, surgical therapy has a satisfactory effect but a higher incidence of complication.

Objective To evaluate ipsilateral hepatic blood flow exclusion in combination with liver hanging manoeuvre for hepatectomy. Methods From Jul 2007 to Feb 2008, 14 cases underwent hemihepatectomy under ipsilateral hepatic blood inflow and draining hepatic vein exclusion in combination with liver hanging manoeuvre for liver malignancier or ligating ligating vessels, portal vein branch and major hepatic vein to set up a tunnel at the interior vena cava. Results Small laceration on fight hepatic vein was encountered in 2 cases during the operation and managed by suturing. There was no intraoperative injury on inferior vena cava or short hepatic veins. Blood loss ranged from 100 ml to 600 ml with a mean of 280 ml. Postoperative pleural effusion was cured conservatively in 3 cases and paracentes was needed in one case. There was no severe postoperative hepatorenal dysfunction, biliary fistula, infection or other major complications. The operative mortality was nil. Conclusion For regular major hepatectomy, ipsilateral hepatic blood flow exclusion plus liver hanging manoeuvre has the advantage of less blood loss and protecting contralateral hemiliver from reporfusion injuries.
