For decades, coping has undergone intensive investigation through different theoretical lens. In this paper, three theoretical standings in coping research were proposed:namely,the process theory, the trait theory and the situation theory. Relevant research and measurements were introduced. In the end, different perspectives were reevaluated and implication for further research was discussed.

Abstract The variation of functional protein C (PC), the activities of total plas. minogen activator and antithrombin Ⅲ (ATⅢ) were observed in canine SMAO shock. The results indicated that under normal conditions, compared with into-pulmonary blood (IPB), in out-pulmonary blood (OPB) the functional PC increased and ATⅢ activity decreased significantly (P

Objective To probe into optimal delivered dose of 131I therapy in hyperthyroidism and influencing factors.Methods Data of 6374 patients with hyperthyroidism receiving 131I therapy were summarized and analyzed.The patients were differentiated into Graves group (GD) and multinodular toxic goiter group (NGD) after 131I therapy.To compare incidence of hypothyroidism between two groups after 131I therapy,partial correlations analysis was performed between delivered dose and other variables influencing factors among cured patients.Results After 131I therapy incidence of permanently hypothyroidismin patients with Graves' group was much higher than that in patients with multinodular toxic goiter group(17.01％,0.39％,Pearson x2 value =704.8,P ＜ 0.01).Delivered dose of 131I therapy related closely to thyroid size,with or without nodules and thyroid rigidity(r =0.469,0.484,0.553).Disposable cured rate of 131I therapy was higher than 63.99％.Conclusion 131I therapy is optimal to multinodular toxic goiter.Delivered dose of 131I therapy will be increased for patients with bigger and stiff mass for therapeutic effects.

This paper introduces the perioperative nursing of 47 patients undergoing intraperitoneal parastomal hernia repair.After the surgery,two cases suffered from incision infection and two cases with subcutaneous hydrops.Three patients suffered from chronic pain or foreign bodies sensation,which disappeared at 3-6 months later.No recurrence occurred at 6-24 months after the surgery.It is suggested that the key points of perioperative nursing were careful preoperative symptom care and bowel preparation,as well as postoperative observation and correct discharge instruction.

Objective: To study the relation of bile acid levels and fetal hypoxia and brain injury in Intrahepatic Cholestasis of Pregnancy (ICP). Methods: From May. 2006 to Sep. 2006, we selected 30 cases of ICP as the study group, and randomly selected 30 cases of normal pregnant women for delivery during the same period as the control group in our hospital. Color Doppler ultrasound was used to measure the peak systolic velocity to end-diastolic velocity (S/D) and the resistive index (RI) of fetal middle cerebral artery, and the automatic biochemical analyzer be used to detect the total bile acid (BA) in maternal blood, and BA, pH as well as lactate in umbilical arterial serum; neuron-specific enolase (NSE) in umbilical artery serum was detected by ELISA. The results were analyzed and compared. Results:①The BA concentration in maternal blood and newborn umbilical artery blood of the study group was significantly higher than that of the control group ( P<0.01). In the study group, the BA in maternal and newborn blood were positively correlated ( r=0.937, P< 0.01) ;②Lactate and the NSE Concentration in newborn umbilical artery of the study group was significantly higher than that of the control group ( P< 0.01). The pH value innewbom umbilical artery and The S/D, RI value of fetal middle cerebral artery in the study group was significantly lower than those of control group ( P< 0.01); ③ In the study group, the NSE concentration was positively correlated with BA and lactate concentration in newborn umbilical artery, while negatively correlated with the S/D and RI values of fetal middle cerebral artery and the pH value in newborn umbilical artery ( P<0.01). Conclusions: There is the existence of hypoxia and brain injury in fetus of ICP. By measuring the blood flow changes of fetal cerebral artery with Color Doppler and detecting pH, lactate as well as NSE levels in umbilical arterial blood, we could early predict the fetal hypoxia and diagnose the fetal brain injury in ICP.

Objective To study the influence of total bile acid (TBA) of maternal serum and cord blood on neonatal cardiac function in women with intrahepatic cholestasis of pregnancy (ICP). Methods The concentration of TBA in the maternal peripheral blood and neonatal cord blood were measured by enzyme in 30 women with ICP as patients group matched with 30 normogravidas as control group. The concentration of cardiac troponin Ⅰ (cTnI) in cord blood was detected by monoclonal enzymelinked immunosorbent assay.Fetal left ventricle Tei index was evaluated by color Doppler uhrasonoscope. Results (1) TBA concentration of maternal serum and cord blood at ICP group were significantly higher than that of control group [ (36.0±9.6) μmol/L vs. (3.8±0.9) μmol/L, (10.1±2.0) p, mol/L vs. (5.5±0.4 )μmol/L,P <0.01 ]. TBA concentration of maternal serum at ICP group was significantly higher than that of neonatal cord blood(P<0.01 ). Meanwhile, TBA concentration of maternal serum at control group was significantly lower than that of neonatal cord blood (P<0.01 ). (2) The Tel index of neonatal left ventricle at ICP group were significantly higher than that of control (0.58±0.04 vs. 0.43±0.03, P<0.01 ). (3) The concentration of cTnI from cord blood(0.92±0.23)μg/L at ICP group were obviously higher than that of control group [ (0.52±0.10)μg/L, P<0.01]. (4) The TBA concentration of cord blood at ICP group showed positive correlation with maternal blood TBA, cord blood cTnI and fetal left ventricle Tei index respectively( r=0.769, 0.635, 0.758,P<0.01). In the mean time, the positive correlation between the concentration of cTnI from cord blood and fetal left ventricle Tel index was also observed (r=0.637.P<0.01). Conclusions Left ventricular dysfunction and myocardial injury were shown in the neonates with ICP, which might be associated with with the elevated TBA level of maternal blood. The Tel index of fetal left ventricle could be used as a reliable parameter to monitor cardiac function and the degree of injured myocardial muscles.

Objective To investigate the anti-erythropoietin antibody level and its clinical significance in maintenance dialysis patients. Methods Eighty maintenance hemodialysis (HD) and 30 peritoneal dialysis (PD) patients were enrolled in the study. Serum anti-erythropoietin antibody levels of above 110 dialysis patients were measured by ELISA. Immunoreactive parathyroid hormone (iPTH), Scr, BUN, Hb, and CRP were determined by conventional methods at the same time. Correlations among these indexes were examined. Results The anti-erythropoietin antibody levels of the dialysis patients were significantly higher than those of healthy people (P＜0.05), but no significant difference was found between HD patients and PD patients. There were no significant differences of anti-erythropoietin antibody, Hb, BUN, Scr, iPTH and CRP among different primary diseases. Hb was negatively correlated with anti-erythropoietin antibody and CRP (r=-0.56, -0.20,P ＜0.05), but was not correlated with BUN, Scr, iPTH. There was no correlation of antierythropoietin antibody with BUN, Scr, CRP and iPTH. One patient receiving recombinant human erythropoietin (rHuEPO) treatment with anti-erythropoietin antibody 43.63 U/L developed pure red cell aplasia diagnosed by marrow biopsy. Conclusions The anti-erythropoietin antibody levels of the dialysis patients are significantly higher as compared to healthy people, but are not significantly different between HD and PD patients. Anti-erythropoietin antibody is not correlated with BUN, Scr,iPTH and CRP. Hb is negatively correlated with anti-erythropoietin antibody and CRP. The rHuEPO can induce the anti-erythropoietin antibody leading to pure red cell aplasia in dialysis patients.
