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 study the effect of mechanical ventilation guided by esophageal pressure on hemodynamics and oxygen metabolism of severe acute pancreatitis (SAP) swine model with intra-abdominal hypertension (IAH) Methods By self-controlled study,SAP model was made by infusing sodium taurocholate (5％) into the pancreatic duct in 6 domestic swine.Mechanical ventilator mode was volumeassist control with tidal volume 10 ml/kg ; FiO2 40％ and PEEP 5 cm H2O (routine ventilation) given to SAP model swine.After 3 h ventilation,pneumo-peritoneum was made with N2 gas to increase the intraabdominal pressure (IAP) to 25 mm Hg in SAP swine.Three more hours later,PEEP was adjusted as the measurement of esophageal pressure (Pes guided ventilation) to such a level that trans-pulmonary pressure stayed above 0 cm H2O during end-expiratory occlusion.During the investigation period,heart rate (HR),cardiac output index (CI),central venous pressure (CVP),mean arterial pressure (MAP) and pulmonary arterial wedge pressure (PAWP) were continuously recorded with the aid of Swan-Ganz catheter and ECG monitor,and oxygen partial pressure of artery (PaO2) and carbon dioxide partial pressure of artery (PaCO2) were measured by blood-gas analysis.In addition,systemic oxygen delivery (DO2) and systemic oxygen consumption (VO2) were calculated by using the data of blood-gas analysis of arterial and central venous blood.Results No swine model was subjected to barotrauma.After routine mechanical ventilation,there were significant differences in HR,CI,MAP,CVP,PAWP,Ppeak,Pplat,Pes,pulmonary compliance (Cstat),PaO2,and DO2 between SAP and IAH in swine (all P ＜ 0.05).Compared with routine ventilation,however,PaO2 and Cstat improved significantly with lower CI and increased Pplat after PEEP adjusted according to measurements of esophageal pressure (all P ＜ 0.05).The lactate decreased significantly after esophageal pressure guided ventilation (all P ＜ 0.05).There were no significant changes in PaCO2,HR,MAP,CVP and PAWP in IAH swine after mechanical ventilation with routine parameters (all P ＞ 0.05).Conclusions There were remarkable effects on oxygen metabolism in response to mechanical ventilation guided by esophageal pressure.In case of clinical application of mechanical ventilation,the results of this study are in favor of setting transpulmonary pressure according to measurements of esophageal pressure in SAP patients with IAH in an early stage.

Objective: The influence on the blood glucose,ALB,LYM,K+,Na+,Cl-,TG,TC and so on after the use of different nutrition formula was observed in patients with cerebrovascular disease and type 2 diabetes.Methods: 40 patients who suffered from cerebrovascular diseases and type 2 diabetes were divided into two groups: one group using the ordinary formula and the others using special-purpose formula of diabetes.The levels of blood glucose,ALB,LYM,K+,Na+,Cl-,TG,TC were monitored.Results: The patient's blood glucose after use of ordinary formula rised obviously and insulin or the oral drug for decreasing blood glucose was used.The blood glucose in special-purpose diabetes formula group didn' t increase obviously,and there was not the need of using insulin(P

Objective • To investigate the current status of self-perceived burden of the patients with non-Hodgkin's lymphoma (NHL) and analyze the related factors. Methods • A total of 169 NHL patients who were hospitalized in Ruijin Hospital, Shanghai Jiao Tong University School of Medicine from Jan. to Oct., 2019, and their caregivers were enrolled by convenience sampling method. The general information questionnaire, Social Support Rating Scale (SSRS), Self-rating Depression Scale (SDS), Zarit Caregiver Burden Interview (ZBI) and Self-perceived Burden Scale (SPBS) were used to investigate, and the factors related to the score of SPBS were analyzed. Results • The average score of SPBS was 28.95±11.27, while the score of economic burden was the highest (3.13±1.37). Multiple regression analysis suggested that the family income per month per person (P=0.001), Karnofsky performance status (KPS) (P=0.027), SDS score (P=0.006) and ZBI score (P=0.000) were associated with the SPBS score in the NHL patients. Conclusion • The overall selfperceived burden in the patients with NHL is mild-to-moderate, but the economic burden is not neglectable. Low monthly income, poor ability of self-care, depressive symptoms and heavy burden of caregivers can aggravate the self-perceived burden of the patients with NHL.

Objective:To investigate the suicidal ideation among unmarried female migrant workers in Shanghai and Guangzhou and explore the association between suicidal ideation and some psychosocial problems, reproductive health factors. Methods:A questionnaire survey was conducted among 3 553 unmarried female migrant workers in two factories in Shanghai and two in Guangzhou by convenient sampling. Logistic regression was used to analyze the related factors of suicide ideation including psychosocial problems and reproductive health factors. Results:Overall, 287(8.1%) of the respondents had suicidal ideation during the past year. Univariate Logistic regression showed that alcohol, low self-esteem, depression, anxiety, loneliness, poor social support (emotional support and economic support), favorable attitude toward premarital pregnancy, favorable attitude toward multiple induced abortion, experience of unplanned pregnancy and experience of induced abortion were related to suicidal ideation after demographic factors being corrected. Multivariate Logistic regression showed that alcohol (OR=1.42, 95% CI 1.04-1.93), low self-esteem (OR=1.47, 95% CI 1.03-2.11), loneliness (OR=3.30, 95% CI 2.42-4.51), poor emotional support (OR=2.68, 95% CI 2.00-3.61) and poor economic support (OR=3.79, 95% CI 2.86-5.04) were the critical factors. Conclusion:The factors such as risk behavior, mental health, lack of social support were associated with increased odds for suicidal ideation among the unmarried female migrant workers. The prevention and intervention mechanism should be constructed, and the social support should be enhanced to effectively prevent the occurrence of suicidal ideation.
