Chinese Journal of Postgraduates of Medicine 2017;40(3):259-262
Objective To compare the effect of different sevoflurane induction methods on hemodynamics and immune function in elderly patients with tumor. Methods One hundred and sixty elderly patients with tumor underwent general anesthesia were enrolled, the patients were divided into observation group and control group according to the anesthesia method with 80 cases each. The observation group was received induction method of initial concentration of 2%sevoflurane and increased by 1% per 3 times breathing and then to a final concentration of 4%- 5%. The control group was received 5% sevoflurane induction concentration. The anesthesia induction time, intubation time, recovery time and untoward reaction were recorded. The changes of heart rate, mean arterial pressure (MAP), oxygen saturation of pulse (SpO2), bispectral index (BIS) and CD3+, CD4+, CD8+, CD4+/CD8+were observed. Results There were no statistical differences in BIS, heart rate, SpO2, CD3 +, CD8 + and incidence of untoward reaction between 2 groups (P>0.05). The MAP at immediate intubation in observation group was significantly higher than that in control group:(69.38 ± 10.42) mmHg (1 mmHg=0.133 kPa) vs. (58.52 ± 6.12) mmHg, but the MAP at after intubation was significantly lower than that in control group: (77.12 ± 11.31) mmHg vs. (90.13 ± 9.24) mmHg, there were statistical differences (P<0.05). The anesthesia induction time and intubation time in observation group were significantly longer than those in control group:(110.1 ± 14.2) s vs. (101.4 ± 15.8) s and (341.2 ± 57.3) s vs. (310.4 ± 60.8) s, but the recovery time was significantly shorter than that in control group: (271.2 ± 31.3) s vs. (321.8 ± 41.5) s, there were statistical differences (P<0.05). The CD4+and CD4+/CD8+at end of surgery and 1 d after surgery in observation group were significantly higher than those in control group, CD4+:0.241 ± 0.027 vs. 0.182 ± 0.034 and 0.332 ± 0.039 vs. 0.284 ± 0.042, CD4+/CD8+: 0.84 ± 0.12 vs. 0.69 ± 0.13 and 1.09 ± 0.52 vs. 0.93 ± 0.43, there were statistical differences (P<0.05). Conclusions Induction method of gradually increasing concentration of sevoflurane enables the hemodynamics of elderly tumor patients more stable. In addition, this method can reduce the inhibitory effect on T lymphocytes to some extent.

Chinese Journal of Comparative Medicine 2016;26(2):22-26
Laboratory animal industry forms an independent, comprehensive system responsible for the production, use and management of laboratory animals.Great advances have been made in this field in China over the more than thirty years of development.However, due to the great development and changes during this long time, there are also some issues which need to be amended and changed.To compare the concepts of experimental animals in China and developed countries such as USA.The key concepts on the laboratory animals are not well or clearly defined in the regulatory documents in China, which hinder the healthy development and effective regulation in this field, as well as the care and use of laboratory animals in research and education.In this article, we discuss the necessity of timely amendment and standardization of the key concepts and definitions related to laboratory animals, and the importance and impact of the key concepts on the development of animal industry in China.
4.Association between stressful life events during pregnancy and adverse pregnancy outcomes: a review
Journal of Preventive Medicine 2023;35(7):587-590
Improving the quality of newborns is a health development strategy, which has attracted global attention. Adverse pregnancy outcomes, including preterm birth, low birth weight and small for gestational age, are major causes of perinatal mortality and disability. Based on review of international and national publications pertaining to associations between stressful life events during pregnancy and adverse pregnancy outcomes from 2007 to 2023, this review summarizes the correlation between stressful life events during pregnancy and adverse pregnancy outcomes, including preterm birth, low birth weight and small for gestational age, and describes the underlying biological mechanisms. Previous studies have demonstrated the associations between maternal stressful life events during pregnancy and adverse pregnancy outcomes, and the underlying mechanisms mainly include neuroendocrine regulation, inflammation and microbiota pathways; however, the exact mechanisms remain unclear until now. Further studies to identify the critical window period for the association between stressful life events and adverse pregnancy outcomes, and unravel the pathogenesis of adverse pregnancy outcomes are warranted, so as to provide insights into reduction of adverse pregnancy outcomes.

Patient′s expectation has been defined as the anticipation that given events were likely to occur during, or as an outcome of, health care. What people expect from their health care are potentially important in predicting patient satisfaction and dissatisfaction with their care, treatment and health outcomes. There was widespread recognition of the importance of evaluating services from consumer perspectives. In this article, domestic and foreign research in recent years, expectations status, significance and various influencing factors in relation to the expectations in processes of health care were summarized. Consumer evaluations of their health care are now an established component of quality assessment, planners need to understand the expectations underlying patients′views in order to interpret their feedback. Thus leading to improve patient satisfaction and the social evaluation of medical units.

OBJECTIVE: To observe the protective effect of soybean isoflavones (SI) on the heart function of the rats with adriamycin induced heart failure. METHODS: Thirty adult male SD rats were divided into 5 groups:normal control (NC) group, adriamycin (ADR) group, L-SI group, M-SI group and H-SI group. SI of 30, 60, 120 mg.kg(-1).d(-1) was orally administered through a stomach tube once a day for 6 days in L-SI group, M-SI group and H-SI group, respectively. The other two groups were given the same amount of normal saline the same way. Then ADR of 10 mg/kg was given intraperitoneally once to copy the model of heart-failure. The MedLab-U/4c biological signal collecting system was used to record and analyze the LVSP of the rats. The pathological changes of the cardiomyocytes were observed. RESULTS: As compared with NC group, the LVSP,+/-dp/dt max, Vpm of the ADR group were significantly lower (P<0.05 or P<0.01), but those of the H-SI group were markedly higher than those of the ADR group (P<0.01). Electron microscopic morphometry of the heart samples of the rats in ADR group revealed typical alterations, consisting an increase of collagen content, vacuolation, diminishing of the cardiomyocyte diameter, alteration of myofilaments and Z-lines of myofibers, and myofibrillar degeneration. SI of 120 mg.kg(-1).d(-1) treatment could prevent the loss of myofibrillae and the reduction of myocyte diameter, and the degeneration of myofilaments and Z-lines were reversed by SI. CONCLUSION: SI of 120 mg.kg(-1).d(-1) treatment can relieve the toxic effect of ADR on myocardium, and also obviously improve the cardiac contractility of heart-failure rats.
