ABSTRACT
Objective To contribute the patient-centered nursing mode and discuss its influence on stress reaction at peri-operational period and postoperative rehabilitation of emmergency surgical patients. Methods A total of 108 emergency surgery patients admitted to Xiangyang No.1 People's Hospital Affiliated of Hubei University of Medicine from January 2014 to January 2017 were enrolled as research subjects, and they were divided into an observation group and a control group according to difference in nursing modes, 54 cases in each group. During the peri-operational period, the patients in control group were given routine nursing mode, while in the observation group, the patients received patient-centered nursing mode. The blood pressure, heart rate and levels of various kinds of hormone (insulin, cortisol, epinephrine) and interleukin-6 (IL-6) before and after intervention were measured; the Hamilton anxiety scale (HAMA) and Hamilton depression scale (HAMD) were used to evaluate the psychological stress changes; after operation, the rate of using analgesics, incidence of postoperative infection, Visual analogue scale (VAS), anus exhaust time, off-bed activity time and sleep quality scale scores were recorded to evaluate the quality of patients' postoperative rehabilitation. Results The diastolic blood pressure, systolic blood pressure, heart rate and levels of insulin, cortisol and IL-6 in two groups before operation and 2 hours after operation were significantly higher than those on admission, while the levels of epinephrine were lower than the level on admission, the degrees of increase or decrease of the observation group were slower than those of the control group, and the changes were more significant at 2 hours after operation [diastolic blood pressure (mmHg, 1 mmHg = 0.133 kPa) was 120.58±13.09 vs. 135.35±15.44, systolic blood pressure (mmHg) was 74.69±10.97 vs. 80.50±11.34, heart rate (bpm) was 83.47±11.64 vs. 92.59±12.00, insulin (mmol/L) was 12.58±1.62 vs. 15.96±1.46, cortisol (μg/L) was 128.72±20.53 vs. 140.47±21.58, epinephrine (ng/L) was 38.96±7.24 vs. 35.25±8.01, IL-6 (ng/L) was 157.64±27.06 vs.183.45±29.37, all P ＜ 0.05]. After interference, the HAMA and HAMD scores of the two groups were significantly lower than those before intervention, and the degree of decrease in the observation group was more obvious (HAMA score: 11.58±2.16 vs. 16.74±2.80, HAMD score: 9.42±2.03 vs. 13.38±2.71, both P ＜ 0.05); the rate of using analgetic [25.93% (14/54) vs. 57.41% (31/54)], incidence of postoperative infection [3.70% (2/54) vs. 16.67% (9/54)], VAS scores (4.63±1.21 vs. 6.87±1.74), anus exhaust time (days: 1.53±0.33 vs. 1.86±0.26), off-bed activity time (days: 1.57±0.19 vs. 1.72±0.24) and sleep quality scale scores (5.84±2.07 vs. 9.33±2.39) in observation group were significantly less than those in control group (all P ＜ 0.05). Conclusion The contribution and application of patient-centered nursing mode in treating emmergency surgery patients during peri-operational period is helpful to ameliorate the patients' degree of physiological and psychological stress reactions, and this mode has important significance in promoting the quality of patients' postoperative rehabilitation.
ABSTRACT
Objective To detect the expression of Fas and FasL in ropivacaine-induced rat phechromocytoma (PC12)cells apoptosis and the mechanism of its neurotoxicity.Methods PC12 cells were treated with different concentrations of ropivacaine (0.1,0.5,1,2,and 4 mmol/L)for 24 h to establish a cellular neurotoxicity model,and the cell viability were assessed by CCK-8.The cells were finally divided into 3 groups randomly:0.5 mmol/L group,2 mmol/L group and control group. After the cells were cultured for 24 h,morphological changes of cells were observed under optical mi-croscope (add the 1 mmol/L group),apoptosis was assessed by flow cytometer,the expression of Fas and FasL were assessed by immunofluorescence.Results Compared with the control group,the cell viability of 0.5 mmol/L and 2 mmol/L group decreased significantly (P<0.05),the cells exhibited obvious morphologic abnormalities (including the 1 mmol/L group),the apoptotic rate increased sig-nificantly (P<0.05),the expression of Fas and FasL increased significantly (P<0.05);Compared with 0.5 mmol/L group,the apoptotic rate and expression of Fas,FasL of 2 mmol/L group increased significantly (P<0.05).Conclusion Ropivacaine explosure induces apoptosis in PC12 cells,which might be related with the up-regulation of Fas/FasL.
ABSTRACT
OBJECTIVE:To optimize the extraction technology of chlorogenic acid in Prunus armeniaca flos,and compare the contents in P. armeniaca flos from different origins and varieties. METHODS:HPLC was conducted to determine the content of chlorogenic acid in P. armeniaca flos;using the volume fraction of ethanol,the ratio of material to liquid,ultrasonic extraction times and time as factor,the content of chlorogenic acid as index,single factor and orthogonal test were designed to optimize the extraction technology,and verification tests were carried out. The optimized extraction technology was used to extract and compare the contents of chlorogenic acid in Armeniaca sibirica from 7 origins of P. armeniaca flos and 3 origins of Armeniaca sibirica flos. RESULTS:The optimized extraction technology was extracting twice with 12-fold 75% ethanol,30 min each time. Under the con-ditions,the content of chlorogenic acid can reach 77.38 mg/g(RSD=0.58%,n=3);the contents of chlorogenic acid in A. sibiri-ca flos and P. armeniaca flos were 77.38-83.33 mg/g and 63.12-70.22 mg/g,respectively. CONCLUSIONS:The established extrac-tion technology is reasonable,stable and feasible. The contents of chlorogenic acid in A. sibirica are higher than that in P. armenia-ca flos;the contents have no obvious differences in the same variety of A. sibirica from different origins.
ABSTRACT
Objective To investigate the relationship between inflammation and blood coagulation function in the patients with acute exacerbation of chronic cor pulmonale (AECCP) and discuss the potential mechanism and influence on the patients. Methods The present study was based on 30 healthy controls and 141 cases of AECCP in our hospital from January 2011 to June 2014.Levels of white blood cell (WBC), neutrophil (NEUT), high-sensitivity C-reactive protein (hs-CRP, Complement 3 (C3), prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FIB) and thrombin time (TT) in the patients were determined. Results Compared with the healthy controls, the patients had higher levels of WBC, NEUT, hs-CRP, PT, APTT, FIB, TT (all P < 0.001) and lower level of C3 (P < 0.001). Significant positive correlations were found between the levels of WBC, NEUT and FIB (r = 0.196 and r = 0.199, both P < 0.05); hs-CRP and APTT, FIB(r = 0.234, P < 0.01 and r = 0.466, P < 0.001); C3 and FIB(r = 0.466, P < 0.001), and significant negative correlations were observed between the levels of C3 and PT, APTT, TT (r=-0.258, P<0.01;r=-0.279, P < 0.01 and r = -0.168, P < 0.05, respectively). Compared with the survival patients, the cases of death had higher levels of WBC and NEUT (both P < 0.01). The area under receiver operating characteristic curve of WBC and NEUT, predicting the prognosis, was 0.666 (95% CI 0.552, 0.780; P < 0.01) and 0.695 (95% CI 0.558, 0.801; P = 0.001) respectively. Conclusions Inflammation and blood coagulation function disorder usually coexist in the patients with AECCP, and are closely associated with the severity. Levels of both WBC and NEUT can be used as prognosis predictors for the patients.
ABSTRACT
Objective To detect serum levels of thyroid hormones in patients with thyroid nodules (TN), and investi-gate their relationship with the nature of TN. Methods A total of 245 patients with TN were recruited in the study. Accord-ing to levels of thyroid antibodies and postoperative pathological results, all patients were divided into nodular goiter (NG) group, thyroid adenoma (TA) group and thyroid cancer (TC) group. TC group was further classified as the TC with increased level of thyroid antibodies (TC-AB+group) and the TC with normal level of thyroid antibodies (TC-AB-group). The serum levels of free T3 (FT3), free T4 (FT4) and thyroid stimulating hormone (TSH) were detected for all patients before operation, and differences of thyroid hormones were analyzed between different groups. Results The serum level of TSH was signifi-cantly higher in TC group than that of NG group and TA group (P<0.05). The serum level of FT3 was significantly lower in TC-AB+group than that of NG group and TC-AB-group. The serum level of FT4 was significantly lower in TC-AB+group than that of NG group, and the serum TSH level was significantly higher than that of other groups (P<0.05). Conclusion The increased serum levels of TSH were found in some patients with TC, which may partly attribute to their coexistence with autoimmune thyroiditis and subsequent hypothyroidism. The increased serum TSH level may not be the inherent characteris-tics of TC.
ABSTRACT
Twenty eight patients with multiple organ dysfunction syndrome (MODS) underwent continuous venovenous hemofiltration (CVVH)in ICU from June 2003 to June 2008, including 13 cases treated with predilution mode and 15 with postdilution mode. The changes of oxygenate index( PaO2/FiO2 )during CVVH were retrospectively analyzed. The total case fatality rate of this group of patients was 46%(13/28). There was a significant increase in PaO2/FiO2 of 28 cases during the first 48 h of CVVH (P ＜0. 05);the levels of PaO2/FiO2 in predilution group had increased significantly within 48 h during CVVH (P＜0. 05), while those in postdilution group had not significantly changed (P ＞ 0. 05). There was a significant increase in Pa02/FiO2 for the survival patients during the first 48h CVVH( P ＜ 0. 05 ), while no significantly change in the fatal cases(P ＞0. 05 ). In summary, oxygenate function and outcome of patients with MODS can be improved by CVVH, and predilution may be a more effective mode.
ABSTRACT
Objective To analyze the pathogeny of acute respiration failure after kidney transplantation on early period and discuss the clinical value of mechanical ventilation.Methods A total of 16 cases of acute respiration failure after kidney transplantation on early period were studied retrospectively.Results The main causes were acute pulmonary edema caused by heart failure and serious pneumonia; patients were divided into two groups according to pathogeny: heart failure group (n=8) and non-heart failure group (n=8). It was found that the patients in heart failure group were older, preoperative blood pressure higher, dialysis duration longer, acute respiratory failure occurred earlier and mechanical ventilation time shorter than in non-heart failure group. The mechanical ventilation could raise oxygen pressure in artery blood and correct hypoxemia quickly. The mechanical ventilation could keep oxygen pressure in artery blood on the ideal level.Conclusion The pathogeny of acute respiration failure after kidney transplantation on early period included acute pulmonary edema caused by heart function failure and serious pneumonia; the mechanical ventilation was important to treat patient with acute respiration failure after kidney transplantation on early period because it could ensure oxygen pressure in artery blood in order to win time to cure heart failure and serious pneumonia. Also, the mechanical ventilation could improve prognosis of the patients.
ABSTRACT
Fu biao who got an advanced liver cancer had undergone liver-transplantation twice and died at last,which raises great ethical concern.With respect to distribution,there are four substantial distributive principles,including the principle of equality,the principle of need,the principle of contribution,the principle of effort.When allocating scarce health-care resouses,medical criteirion should be considered firstly the equality of everyone's life.Furthermore,the principle of utility and equality should be embodied for ensuring distributive justice.
