OBJECTIVE: To explore the influence of psychological factor on asthma, the protective and therapeutic effects of Shugan Lifei Recipe on rats with asthma under stress and the mechanisms. METHODS: Allergy and stress-induced asthma models were established in rats by giving ovalbumin and restraining stress. Radioimmunoassay, enzyme linked immunosorbent assay, in situ hybridization and immunohistochemical method were used to detect plasma corticosterone, IL-4, IFN-gamma, expression of glucocorticoid receptor (GR) mRNA in hippocampus and adrenocorticotropic hormone corticoliberin (CRH) positive neuron in hypothalamus. Optical and electron microscopes were used to observe the morphological changes of pulmonary hilar and hippocampal tissues. RESULTS: Shugan Lifei Recipe (SGLFR) could reduce plasma corticosterone, decrease CRH positive neurons in paraventricular nucleus of hypothalamus, up-regulate the expression of GR mRNA in hippocampus and reduce the injury of hippocampal neuron. SGLFR had certain inhibitive effect on hyperfunction of hypothalamo-pituitary-adrenal cortex (HPA) axis in rats with asthma under stress and could also relieve the pathological changes of the pulmonary hilar tissue. The level of plasma IFN-gamma was increased while the level of plasma IL-4 was decreased in SGLFR-treated group. CONCLUSION: The mechanism of SGLFR in treating the rats with asthma under stress is probably to regulate the hyperfunction of HPA axis and the disorder of immuo-system.

Objective To investigate different dosage of dexmedetomidine for preventing elderly postanes-thetic shivering.Methods 100 ASAⅠ~Ⅱ elderly patients (60~80 ages)scheduled for laparotomy were enrolled in this study.According to a computer-generated list of random numbers,patients were randomly allocated to receive dexmedetomidine in the four groups:group A (0.9%normal saline),group B (dexmedetomidine 0.25μg/kg),group C (dexmedetomidine 0.5μg/kg),group D (dexmedetomidine 0.75μg/kg).The occurrence of postanesthetic shive-ring and adverse reactions in perioperative period and post operation were observed.Results The incidence rate shiv-ering were 24% and 20% in group C and D,which were significantly lower than 64% in group A (χ2 =5.333,6. 876,all P<0.05),but there was no difference between C and D groups(χ2 =0.117,P>0.05).Rectal temperature was no difference among four groups(F=1.271,P>0.05).Extubation time was shorter in group A(21.6 ±4.0)min than that in group D(24.4 ±2.8)min(F=6.194,P<0.05).Conclusion Our results suggest that dexmedetomi-dine 0.5 or 0.75 μg/kg can prevent shivering after general anesthesia effectively.But potential for delayed extubation time with dexmedetomidine was noted.The loading dose of 0.5 μg/kg dexmedetomidine is recommeded to prevent eld-erly shivering after general anesthesia.

Objective To evaluate the efficacy of the sublingual immunotherapy with Dermatophagoides farianae drops on different age groups. Methods The efficacy of 117 patients with AR received SLIT treatment for more than one year were retrospectively analyzed. These patients were divided into three groups according to the age,children group(6-14 year old,35 patients),youth age group(15-35 year old,45 cases)and middle-aged group(36-66 year old,37 pa-tients). Before and SLIT treatment for half one year, one year,symptom score, medication score and signs score were evaluated. Results After SLIT treatment for half a year and one year, the symptom score, medication score and signs score in these patients significantly reduced compared with before(P<0.05). Compared with after half a year treatment,the symptom score of children group significantly reduced(q=3.05,P<0.05),and other indicators were not statistically significant (P>0.05). The symptom score, medication score and signs score among three age groups were not statisti-cally significant (P>0.05) at all the time points. Conclusion Dermatophagoides farinae drops on allergic rhinitis can play a significant and similar effect in the different age groups.

Objective:To observe the effect of goal-oriented management of continuous monitoring of regional cerebral oxygen saturation (rSO 2) on early postoperative neurocognitive disorders (PND) in elderly spinal surgery patients. Methods:From November 2018 to July 2019, 60 patients undergoing posterior lumbar interbody fusion in the Second Hospital of Shanxi Medical University were selected and randomly divided into control group and intervention group, 30 cases in each group. RSO 2 was recorded before anesthesia induction (T 0), 10 min after anesthesia induction (T 1), 10 min after prone position (T 2), 10 min after spinal decompression (T 3), 30 min after spinal decompression (T 4) and 10 min after extubation (T 5); The basic value of rSO 2, the minimum value of rSO 2 (rSO 2min), the average value of rSO 2 (rSO 2mean) and the maximum percentage of decrease of rSO 2 (rSO 2% max) were recorded. When rSO 2 <55% or rSO 2% max >10% and the duration was longer than 15 s, the intervention group took measures such as adjusting head position, adjusting blood pressure, increasing FiO 2 and respiratory parameters, increasing P ETCO 2 until rSO 2 returned to the required range; The control group did not interfere with the intraoperative rSO 2. Neuropsychological tests were used to evaluate the cognitive function of the two groups 7 days after operation. The patients were followed up 30 days after operation with the revised cognitive function telephone questionnaire (TICS-M). The incidence of postoperative neurocognitive impairment (PND) was recorded. The perioperative data and postoperative adverse reactions of the two groups were recorded. Results:At T 3 and T 4, the rSO 2 of the intervention group was significantly higher than that of the control group ( P<0.01), the intraoperative rSO 2min and rSO 2mean of the intervention group were higher than the control group, and the rSO 2%max was lower than the control group ( P<0.05). The incidence of PND 7 days after surgery, extubation time, postanesthesia care unit (PACU) stay time, hospital stay and postoperative adverse reactions in the intervention group were lower than those in the control group ( P<0.05). There was no significant difference in the incidence of PND 30 days after operation between the two groups ( P>0.05). Conclusions:The goal-oriented management of rSO 2 can reduce the incidence of early postoperative PND in elderly spine surgery patients, which is conducive to the rapid recovery of patients after surgery.

Objective: To analyze the mental health status and its impact factors among nurses, finding ways to improve the mental health of nurses. Methods: A total of 13 425 female healthcare workers aged from 18 to 65 were selected as study objects. The survey was conducted with unified design questionnaire. The survey included the basic situation of the individuals and SCL-90 questionnaire. Comparing the female doctors, the mental health status and its impact factors of nurses were analyzed. Results: The income, age, education and occupation, which include shift work, heavy work load and overtime work are different between nurses and doctors. The main mental health problems of nurses were obsessive-compulsive symptoms, depressive symptoms and somatization. The results of univariate analysis indicated that shift work, overtime work, and heavy work load affected the positive rate of each factor. The results of multivariate analysis showed that occupation, shift work, overtime work, and heavy work load have significant adverse effects on the positive rate of the total score in female healthcare workers (P<0.01) . The positive rate of each dimension of SCL-90 in nurses is significantly higher than that of doctors. Conclusion The mental health problems of nurses are significantly higher than doctors. The main reasons are low occupational level and adverse workstyles which include shift work, heavy workload and so on. Health administration and hospital management departments should pay much more attention to the mental health of nurses, improving their mental health through a variety of ways.
