ABSTRACT
Noise is one of the most common environmental hazards to which people are exposed,and the exposure to noise can cause not only hearing but also non-hearing damage.Although noise under safety limits may not affect the auditory system,it can cause changes in stress hormone levels,which is harmful to health.However,the current studies about the impact of noise on health mainly focus on the auditory system,and little is known about the relationship between noise and stress hormone levels.Therefore,this paper reviews the studies involving noise exposure and stress hormone levels,aiming to provide ideas for strengthening the prevention and control of noise hazards.

Objective To discuss the effects of lidocaine infusion on perioperative immune function by evaluating the levels of stress hormone and natural killer (NK) cell cytotoxicity.Methods Thirty-five patients of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,aged 35-65 yr,undergoing elective radical hysterectomy,were randomized into lidocaine group (group L)and control group (group C).Fifteen minutes before anesthesia induction,a bolus of 1.5 mg/kg of lidocaine was administered iv.to each patient in group L and followed by a continuous infusion at 1.5 mg·kg-1 ·h-1 lasting to the end of surgery.Meanwhile,the patients in group C received the same volume of saline.Venous blood samples were collected individually 24 h before the operation,the end of the operation and 48 h after the operation.Levels of prostaglandin,epinephrine and norepinephrine were assayed by ELISA kits.NK Cells were obtained by CD56 antibody magnetic isolation.The cytotoxicity of NK cell was detected by LDH releasing assay,and phosphor-protein kinase A (p-PKA)and protein kinase A (PKA) were detected by Western blotting.Results There were no significantly different in the plasm levels of PGF2,EP1 and NE.The plasm levels of prostaglandin (562.5±98.2 vs.663.2±119.0) pg/ml,epinephrine (24.9±4.8 vs.29.7±3.5) pg/ml and norepinephrine (408.3 ±47.2 vs.499.6±45.6) pg/ml in patients of group L were lower than those in group C (P＜0.05)48 h after the surgery.The cytotoxicity of NK cell was higher in group L than that in group C (44.1 ±5.0 vs.37.1±5.5)％ (P＜0.05) 48 h after the surgery.The ratio of p-PKA/PKA was lower in group L than that in guoup C (0.060±0.008 vs.0.099±0.011) (P＜0.05) at the end of the surgery.Conclusion Perioperative intravenous lidocaine infusion can reduce the level of plasma catecholamine and PGE2,and protect the cytotoxicity of NK cell,possibly via inhibiting of cAMP-PKA signaling pathway.
ABSTRACT
Objective To compare the serum index after colonoscopy high-frequency electric snare combined with nylon cord ligation and high-frequency electric resection in treating broad pedicle polyps. Methods 70 cases of broad pedicle polyps patients from July 2012 to May 2016 were chosen as research object. The operation methods and laboratory examination results of all the patients were reviewed. All patients were divided into observation group (n = 37) and control group (n = 33). Patients in observation group were treated by colonoscopy high-frequency electric snare combined with nylon loop ligation, while patients in control group were treated by high-frequency electric resection only. The blood loss and related indexes of the two groups were recorded. Before and after operation, stress hormones and acute phase proteins in serum was determined. Results Intraoperative blood loss of observation group was less than that in control group, postoperative hemoglobin levels was higher than that in control group, postoperative early bleeding rate, postoperative delayed bleeding rate of observation group were lower than that in control group (P < 0.05); 1 hour after surgery, Cor, ACTH, AT II, NE, CRP, SAA, AAT in serum were lower than those in control group (P < 0.05). Conclusion Through colonoscopy high-frequency electric snare combined with nylon cord ligation can reduce bleeding during and after surgery, relieve stress and inflammation.

Among them 36 cases of video-assisted thoracoscopy lung cancer radical surgery for the treatment of patients in mind as the observation group, 36 cases of open chest lung cancer radical operation were recorded as control group, respectively comparing two groups of patients with preoperative and postoperative 3 days red cell immune index, index of cellular immunity, stress hormone level and blood rheology index.Results:3 days after operation, the observation group in terms of RBC-C3b, RFER levels were significantly higher than those of control group and RBC-IC and RFER were significantly lower than those in the control group. 3 days after operation, the observation group CD3+, CD4+, CD3+CD4+ were significantly higher than those of the control group, while CD8+ was significantly lower than that of the control group. 3 days after operation, the observation group NE, Cor, angiotensin II (ANG II) was significantly higher than that of the control group (t=2.181,t=10.320,t=5.924;P<0.05). 3 days after operation in observation group, the plasma viscosity, erythrocyte sedimentation equation K value were significantly lower than those in the control group. The differences were statistically significant (t=29.698,t=7.411;P<0.05).Conclusion:The side-effect of thoracoscopy radical resection of lung cancer is small, and it has more advantages compared with open chest lung cancer radical operation.
ABSTRACT
Objective:To compare the effects of different anesthesia methods on stress hormones and hemodynamic changes in the patients with gynecological laparoscopic surgery. Methods:Retrospective analysis was carried out. Totally 145 patients with gynecolog-ical laparoscopic surgery were divided into two groups according to the anesthesia method, the control group with 72 cases was given routine remifentanyl propofol intravenous anesthesia, and the observation group with 73 cases was given routine propofol isoflurane com-posite anesthesia. Such hemodynamic indices as SBP, DBP and HR, and plasma NE, E, cort and AT II levels at different time points in the two groups were studied and compared, and adverse drug reactions were also observed in the two groups. Results:The BP and HR at T2 and T3 time point in the two groups were significantly lower than those at T0 time point (P<0. 05), and those in the obser-vation group were lower than those in the control group at the same time point(P<0. 05). The levels of NE, E, cort and ATⅡat T2 and T3 time point in the two groups were significantly higher than those at T0 time point (P<0. 05), while the increase in the observa-tion group was lower than that in the control group (P<0. 05). The incidence of adverse drug reactions (ADR), such as respiratory depression, hypertension, bradycardia and so on, and the total incidence of ADR in the observation group were both lower than those in the control group (P<0. 05). Conclusion:Compared with remifentanyl propofol intravenous anesthesia, propofol isoflurane composite anesthesia can keep the hemodynamic stability more effectively and reduce the stress reaction with fewer ADR and promising safety, which is worthy of wider application in clinics.
ABSTRACT
To explore the analgesic effect of propofol combine with dezocine after painless abortion and the influence on stress hormone and hemodynamics of the patients. Methods:Totally 126 cases of patients with painless abortion in our hospital from March 2013 to March 2014 were randomly divided into the observation group and the control group with 63 ones in each. The observa-tion group was anesthetized with propofol combine with dezocine, while the control group was anesthetized only by propofol. The dosage of propofol, anesthesia effect and postoperative recovery of the patients in the two groups were compared, and the level of stress hor-mones and hemodynamic parameters before and after the surgery were also compared. Results: Compared with that in the control group, the dosage of dezocine and the score of VAS after the surgery was significantly reduced in the observation group with obviously better anesthesia effect, and the differences had statistical significance (P<0. 05). The level of Cor, NE and ACTH was significantly improved, and the level of A-I and A-II was reduced significantly in the observation group, and compared with that in the control group, the differences showed statistical significance(P<0. 05). Compared with those that in the control group, the levels of SBP, DBP and SpO2 were improved significantly and the level of HR was reduced significantly in the observation group during and after the surgery, and the differences showed statistical significance (P<0. 05). The incidence of adverse drug reactions in the observation group was significantly lower than that in the control group, and the difference had statistical significance (P<0. 05). Conclusion:Propofol combine with dezocine for the surgery of painless abortion can reduce the dosage of dezocine, improve the anesthesia effect and reduce the harem pain with lower stress hormone fluctuation, hemodynamic effect and incidence of adverse reactions.
ABSTRACT
Aims and objectives: We studied efficacy of caudal dexmedetomidine (DEX) on attenuation of perioperative stress response and postoperative pain in pediatric patients undergoing cardiac surgery. Materials and Methods: Forty patients, (ASA II, III), 1-3-years old were randomly allocated into two groups; group BD received caudal bupivacaine 0.25%, 2.5 mg/kg and DEX 0.5 μg/kg and group BF received bupivacaine 2.5 mg/kg and fentanyl 1 μg/kg. Results: Serum cortisol and blood glucose levels increased in both groups but increases were significantly less in group BD. Poststernotomy cortisol level (ug/dl) was 55.3 ± 5.1 vs. 90.4 ± 6.5; after cardio-pulmonary bypass (CPB) 84.1 ± 6.2 vs. 153.1 ± 8.5; after operation 78.3 ± 8.1 vs. 150.2 ± 9.8. Poststernotomy blood glucose level (mg/dl) was 93.6 ± 7.2 vs. 125.6 ± 5.5; after CPB 115.3 ± 3.7 vs. 175.3 ± 10.4; and after operation 97.3 2 ± 3 vs. 162.2 ± 12. Heart rate and mean arterial pressure decreased significantly after caudal block in group BD relative to the baseline and compared with group BF ( P < 0.05). Group BD had lower pain scores at first hour 2 ± 0.7 vs. 3 ± 1.1 ( P = 0.04); second hour 1.9 ± 0.5 vs. 3.7 ± 0.8, ( P = 0.008); fourth hour 2.4 ± 0.8 vs. 4.3 ± 0.5 ( P = 0.03); and eighth hour 2.5 ± 0.5 vs. 4.2 ± 1.1 ( P = 0.03). Conclusions: Caudal DEX attenuated stress response to surgical trauma and provided better postoperative analgesia.

BACKGROUND AND PURPOSE: The present study was designed to investigate whether 24 h of SD negatively affects the attention and working memory and increases the serum concentrations of stress hormones, glucose, and inflammatory markers. METHODS: The acute effects of sleep deprivation (SD) on cognition and the stress hormones were evaluated in six healthy volunteers (all men, age 23-27 years). All were good sleepers, had no history of medical or neuropsychiatric diseases, and were not taking any kind of medication. All of the volunteers were subjected to the Continuous Performance Test (CPT) for attention and working memory of cognition and blood tests both before and after 24 h of SD. Electroencephalographic monitoring was performed during the study to confirm the wakefulness of the subjects. RESULTS: SD significantly elevated the serum concentrations of stress hormones (cortisol, epinephrine, and norepinephrine), but serum levels of glucose and inflammatory markers were not changed compared to baseline. For easier steps of the CPT the subjects performed well in giving correct responses after SD; the correct response scores decreased only at the most difficult step of the CPT. However, the subjects performed consistently poor for the error responses at all steps after SD. There was no correlation between the CPT scores and stress hormone levels. CONCLUSIONS: The 24 h of SD significantly heightened the levels of stress hormones and lowered attention and working memory. The acute SD condition seems to render the subject more susceptible to making errors.

We analyzed the relation between subjective fatigue by hard exercise and stress hormone and cytokine data. The subjects are eight healthy men who had exercise experience. In this experiment, hard exercise was carried out in the first place. After two-hour rest, a performance test was carried out. The blood test was conducted 4 times (before exercise, after exercise, rest, and a performance test). Subjective fatigue was indicated using visual analogue scale (VAS). After the hard exercise and performance test, VAS increased and showed the significant difference. Lactic acid, adrenaline, noradrenaline, growth hormone, IL-6, and IL-8 increased after each exercise and showed the significant difference. Subjective fatigue and the value of lactic acid, and IL-6 showed significant positive correlations. These results suggest that lactic acid, and IL-6 may become an index of fatigue in this exertion model.<br>
ABSTRACT
Regular exercise training improves body composition, blood lipid profiles and exercise adaptation. This study was conducted to investigate the effect of exercise training at different times of day on body composition, blood lipids, stress hormones and nutrient intakes. Twenty four male graduate students carried out this experiment. The subjects were divided into three groups; morning exercise group, evening exercise group and control group. Two exercise groups performed running and muscular resistance training at mid intensity for 12 week periods. Body composition, blood lipid profiles, blood cortisol, ACTH and nutrient intakes were analyzed prior to, midway and after training. There were significant differences about interaction between different exercise times and training periods in plasma TG and HDL-C of the evening exercise training (p < 0.05). Also the evening exercise group was showed the decreasing of TC after training (p < 0.05). No significant differences about interaction between different exercise times and training periods were shown in body composition, stress hormones and nutrient intakes in the three groups. But evening exercise training decreased body fat (%) and blood ACTH (p < 0.05). Also the increasing of carbohydrate intakes was shown by the evening exercise training (p < 0.05). In contrast, morning exercise group indicated a decrease of body fat (%) after 6 week training (p < 0.05), but this effect was not maintained after 12 weeks of training. These results suggested that regular evening exercise is more effect than morning exercise from the viewpoint of improving body composition, blood lipids, nutrient intakes and exercise adaptation.

PURPOSE: This study was done to evaluate the effects of massage on the level of stress hormone in the urine in preterm infants. METHOD: The design was a nonequivalent control group pretest-posttest design quasi experimental study. Fifty-eight preterm infants were assigned to the experimental(31) or control group(27). The data were collected from March 2002 to August 2003. The massage stimulation was provided to infants in the experimental group for 15-minutes twice a day for 10 days. On day 1 and day 10 of the study, a 24 hour-urine sample was collected for norepinephrine, epinephrine, and cortisol assays. In data analysis, SPSSWIN 10.0 program was utilized for descriptive statistics, ANOVA and t-test. RESULTS: General characteristics of the two groups showed no significant differences, thus the two groups were found to be homogenous. The 24 hour-urine cortisol of the massage group (t=4.61, p=.000) was significantly reduced compared to the control group after 10 days. CONCLUSIONS: The results suggest that the massage stimulation can be used to reduce 24 hour-urine cortisol in preterm infants. Therefore, massage provided in the incubator is recommended for reduction of stress in preterm infants who are hospitalized in neonatal intensive care units.

PURPOSE: This study was done to determine whether providing auditory and vestibular stimulation to preterm infants would have an effect on stress hormones. METHODS: The design was a nonequivalent control group pretest-posttest design in a quasi-experimental study. Seventy-nine preterm infants were assigned either one of two experimental groups or to a control group: 27 in the auditory stimulation group, 25 in the vestibular stimulation group and 27 in the control group. The criteria for inclusion in this study were 1) gestational age of less than 37 weeks, 2) birth weight of less than 2,500g, 3) the absence of congenital anomalies or specific diseases, 4) recovering physiological weight loss, and 5) weaned from ventilatory assistance or oxygen. The data were collected from March 2002 to May 2003. The auditory stimulation, a music audiotape, was provided 20 minutes twice a day for 10 days and the vestibular stimulation, an infant waterbed, was provided for 10 days. On day 1 and day 10 of the study, 24 hour urine sample was collected for norepinephrine, epinephrine, and cortisol assays. In the data analysis, SPSSWIN 10.0 program was utilized for descriptive statistics, ANOVA and t-test. RESULTS: General characteristics of the three groups showed no significant differences, thus three groups were found to be homogenous. The 24 hour urine cortisol for the auditory (t=3.489, p=.001) and for the vestibular (t=2.638, p=.013) stimulation group were significantly reduced compared to the control group after 10 days. CONCLUSION: The results suggest that auditory and vestibular stimulation can be used to reduce 24 hour urine cortisol in preterm infants. Therefore, music audiotapes and waterbeds provided in incubator are be recommended for reduction of the stress in preterm infants who are hospitalized in neonatal intensive care units.

BACKGROUND: The aims of the study were to evaluate hemodynamic and stress hormone responses during abdominal hysterectomy under enflurane anesthesia supplemented by continuous ketamine infusion. METHODS: Eighteen patients scheduled for elective abdominal hysterectomy under enflurane anesthesia were randomly assigned to two groups, which received intravenous ketamine (0.3 mg/kg initially, followed by a continuous infusion at a rate of 0.15 mg/kg/h) (ketamine group, n = 9) or normal saline (control group, n = 9) 2 min after intubation. Hemodynamic responses, serum cortisol, prolactin, growth hormone, insulin and glucose concentrations were measured before induction, 2 min after intubation, 2 min after incision, at peritoneum closure, and 5 min after extubation. RESULTS: No significant differences were observed between the two groups in terms of hemodynamic responses, serum cortisol, prolactin, growth hormone, insulin and glucose concentrations. Compared with values before induction, significant increases in serum cortisol, prolactin, and glucose concentrations were observed at peritoneum closure and 5 min after extubation in both groups. However, growth hormone levels in the control group, and insulin concentration in both groups were significantly reduced 2 min after skin incision (P < 0.05). CONCLUSIONS: Bolus ketamine 0.3 mg/kg IV followed by a 0.15 mg/kg/h infusion fails to suppress stress responses, such as increases in serum cortisol, prolactin, growth hormone, and glucose concentrations, or insulin reduction at surgery under enflurane anesthesia.

ABSTRACT
The purpose of this study was to investigate the effects of exercise therapy and relaxation therapy on catecholamine and heart rate in people in white color jobs and to determine this information the effectiveness of applied exercise therapy and relaxation therapy as a nursing intervention method for stress patients. The subjects were divided into an exercise therapy group, a relaxation therapy group, and control group and the research design was a nonequivalent control group pretest-post test design(exercise therapy : n=12, relaxation therapy : n=12, control group, the group without any treatment in exercise on relaxation therapy : n=12). The subjects in the exercise therapy group were given a particular intensity for each kp during 30min, bicycle ergometer which is using an LX PE training system before & after 4weeks of training. The exercise therapy that was used was Astrard load method which tested absolute exercise load of heart rate before & after four weeks, and resting heart rate was tested for exercise and relaxation therapy before, after four weeks, and at eight weeks. The results of each kp & absolute exercise load were calculated with the target rate formula(maximal heart rate-rest heart rate) x exercise intensity(%) rest heart rate so the subjects could continue 60-70% exercise intensity for exercise therapy over eight weeks. The relaxation therapy subjects were trained using a modified Jacobson's relaxation technique for eight weeks. The exercise and relaxation therapy were trained at the following intensity for eight weeks(3 times/week, 30 min/day) to see changes in catecholamine & heart rates. After eight weeks, statistical analysis of exercise & relaxation therapy were carried out Two-way ANOVA and multiple range test(SNK : Student Newman Keul) were used. The results are as follows : 1. The change of epinephrine & norepinephrine in the exercise therapy, relaxation therapy, and control group was statistically significant at the .05 level after four weeks & eight weeks. Also, exercise therapy was statistically significant at .05 level over that of the control group after 4 weeks. 2. The change of heart rate in relaxation therapy was statistically significant at the .05 level, and was statistically significant at the .05 level over that of the exercise therapy and control group. In conclusion, it is obvious that exercise therapy and relaxation therapy should be one of the most effective stress treatment and desirable nursing interventions methods for job stress in people in white color jobs.

This study has been conducted on the nonequivalent control group pretest-posttest design in quasi experimental basis and newly born premature infants from intensive care unit of G Medical University Hospital in Inchon Metropolitan were selected in two groups of 21 infants each. The first group for experimental and the other for control. Data has been collected form October 30, 1997 to August 29, 1998. For the experimental group tactile and kinesthetic stimulation was applied 2 times a day for 10 days(10:00~11:00 hours in the morning and 17:00~18:00 in the afternoon). As a weight weighing instrument, electronic indicator scale(Cas Co, Korea) was used. To determine urine cortisol concentration level in stress hormone, radio immuno assay method was used. And high performance liquid chlomatogarphy was used to determine urine norepinephrine, concentration level. To determine behavior status, tools developed by anderson et al(1990) and remodeled by Kim Hee-Sook(1996) were used. Collected data were analyzed with the SAS program using x2-test, student t-test, repeated measures ANOVA and paired t-test. The result were as follow. 1. As for the daily weight gain, the experimental group showed first change in weight and this group also showed higher weight in the average weight than the control group. Statistically, however, there was no significant factor between the two groups. 2. The cortisol concentration in urine showed decrease in the experimental group norepinephrine concentration in urine showed increase in both experimental and control groups. No statistical significance was shown between the two groups. 3. In the aspect of behavior status, the experimental group showed statistical significance by showing inactive in the state of alert and conversion to a positive state than the control group. In conclusion, the sensory stimulation in this study showed a positive aspect through there was no statistical significance n the weight gain and urine stress hormone concentration. In the behavior status, there was statistical significance in the frequency of staying inactive in the state of alert and conversion to a positive state.
