The experiment was undertaken to investigate the influences of ligation of the common bile duct (CBD) and pulling the gallbladder on the left ventricular function. Fourteen rabbits served as the subjects with the CBD being tied off. The cathter was inserted into the left ventricle to measure left ventricular stroke pressure (LVSP) and?dp/dt, which were recorded before and 5 days after the ligation of CBD respectively. The results showed that the value of +dp/dt decreased significantly (P0.05); LVSP, SP, HR and the values of ?dp/dt reduced markedly immediately after the gallbladder being pulled (P

Oyecave:To observe the influence of nociceptin/orphanin FQ(N/OFO)on cerebral infarction volume and somatosellsOry evoked potential(SEP)in focal cerebral ischemia in rats.Methods:Forty one SD rats were randomly alloomed into middle artery occlusion(MCAO)sham-operation(n=5),isehemic(n=8),N/OFQ 10μg(n=7),N/OFQ 1 μg(n=7),N/OFQ0.1 μg(n=7),and artificiai cerebrospinal fluid(ACSF)(n=7)groups.A model of middle cerebral artery occlusion(MCAO)in rats was induced using intraluminal suture method.Reperfusion was performed 2 hours after MCAO.One hour after MCAO,N/OFQ 10 μg,N/OFQ 1 μg,N/OFQ O. 1 μg,and the same volume of ACSF were injected intraventricularly in the N/OFQ 10 μg,N/OFQ 1 μg,N/OFQ 0. 1 μg,and ACSF groups,respectively. The cerebral infarction volurne was detected 24 hours after reperfusion,and SEP was recorded. Results:1he amplitude of SEP P1 decreased in the sham-operation group. There was no significant change in P1 peak latencies.There were no significant differences hetween the N/OFQ 0. 1 μg group and the ACSF group in SEP amplitudes,P1 peak lantecies and cerebral infarction volume. As compared with the ACSF group,the SEP amplitudes were further decreased in the N/OFQ 1 μg and N/OFQ 10 μg groups,but there were no significant change in P1 peak lantecies. One hour after reperfusion,the SEP amplitude in the ACSF group almost returned to the level of preischemia,the recovery slowed down in the N/OFQ 1 μg group,and it still did not recovered 3 hours after reperfusion in the N/OFQ 10 μg group. The dose of N/OFQ and SEP response showed dose-effect relationship,The higher the dose,the deeper the SEP depression and the slower the recovery. At 24 hours after reperfusion,the cerebral infarction vlumes in the shamoperation,ACSF,N/OFQ 0. 1 μg,N/OFQ 1 μg,and N/OFQ 10 μg groups were 0 mm3,24.180 ±4.088 mm3,23.090±4.523 mm3,35.304 ± 6. 824 mm3,and 40. 806±6. 716 mm3,respectively. There was no significant difference between N/OFQ 0. 1 and ACSF groups. There were significant differences between N/OFQ 1 μg and 10 μg groups and ACSF group (all P ＜ 0.01 ). Conclusions:Intracerebroventricular injection of N/OFQ in the early stage of cerebral ischemia decreases the SEP amplitude,prolongs the time of recovery,and increases cerebral infarction volume,which shoves that it may aggravate cerebral ischemic injury.

Objective To evaluate the prophylactic effect of abdominal breathing exercises on radiation pneumonitis in patients with chest malignant tumors.Methods 100 patients with chest malignant tumors were given radiotherapy and divided with random digit table into the exercise group and the control group with 50 patients in each group.The incidence rate of radiation pneumonitis in both groups was compared.The prophylactic effect of abdominal breathing exercises on radiation pneumonitis was evaluated.Results The incidence of radiation pneumonitis in abdominal breathing exercise group was significantly reduced [34％ (17/50) vs.56％ (28/50),Z=2.397,P＜0.05],the incidences of grade Ⅰ [22％ (11/50) vs.30％ (15/50)] and grade Ⅱ [12％ (6/50) vs.18％ (9/50)] radiation pneumonitis decreased,and no grade Ⅲ and Ⅳ radiation pneumonitis occurred.Conclusions The incidence of radiation pneumonitis in patients with chest malignant tumors treated with radiation therapy may be decreased by abdominal breathing exercises,which may be widely applied in patients treated with radiation therapy.

Objective To analyse the relationship between the personality and occupation tension of anesthesiologists.Methods One hundred anesthesiologists working at different hospitals in Shenzhen volunteered to complete the questionnaire.Ninety-one valid questionaires were recovered.The questionnaire survey included the Eysenck Personality Questionnaire and Job Content Questionnaire and anesthesia events.The standard scores of internal and external factor,stubborn factor,emotional stability factor,social support,sense of personal achievement and work demand/control ratio (D/C) were calculated.Results Internal and external factor (E) and stubborn factor (P) were negatively correlated with demand/control ratio (D/C).The correlation coefficients were-0.7805and-0.2375.There was no correlation between emotional stability factor (N) and D/C.Social support and sense of personal achievement were negatively correlated with D/C.The correlation coefficients were-0.225 and -0.264.More than 50％ of the study subjects suffered from mental tension during op.eration and fatique after night shift,overtime work and emergency operation.Conclusion Occupation tension is lower in extroverted and higher in introverted anesthesiologists and is also relatively low in those with stubborn personality.Strong social support and deep sense of personal achievement can lower occupation tension.

A total of 5 010 cases,2 163 males,2 847 females were included in this study.Investigation contents included health questionnaire,anthropometric and laboratory detection.According to the Framingham Risk Score (FRS),10 -year risk probability of cardiovascular disease was calculated.Research subjects were divided into low risk group (<10%),medium risk group (≥10% and <20%),high -risk group (≥20%),and logistic regression was used to analyze the risk degree of the related risk factors.Results The 10 -year cardiovascular risk median value of 60 -70 years elderly residents was 8.0 (4.0 -16.0),among them male was 16.0 (12.0 -20.0),female was 4.0 (2.0 -6.0).Low risk group had 2 784 cases,accounted for 55.7%;medium risk group had 1 452 cases,accounted for 29.0%,high-risk group had 774 cases,accounted for 15.3%.The most important risk factors were smoking and cholesterol increasing,who contributes elderly residents aged 60 to 70 years in Renqiu cardiovascular 10 -year risk.The history of stroke,excessive drinking,waist circumference,diastolic blood pressure,elevated uric acid level and HOMA -IR were the independent risk factors in moderately high risk 10 -year probability of cardiovascular.Conclusion The elderly residents aged 60 to 70 years in Renqiu has higher cardiovascular risk of 10 years.Quitting smoking,limitting alcohol,controlling of blood pressure,blood lipids,uric acid,waist circumference and HOMA -IR are important to improve cardiovascular 10 -year risk.Among them,quit smoking and alcohol limit are the most effective measures.

Objective To investigate the potential relationship between the characteristics of atherosclerotic plaque of carotid artery and cardiovascular events in a senior cohort of Renqiu region,Hebei.Methods A random cluster sampling method was used to identify study population among 60 -70 years old residence in Renqiu region, Hebei.In the face of health questionnaire survey,neck vascular ultrasound examination,a total of 4 413 cases,inclu-ding 1 876 males and 2 537 females,the occurrence of carotid artery plaque and stenosis were detected by ultrasound. Carotid ultrasound was used to identify the characteristic of atherosclerotic plaque of bilateral carotid arteries,which were categorized as with and without plaque,single and multiple plaque,homogenous and heterogeneous plaque,and with and without stenosis.Cardiovascular events were defined as composite events of myocardial infarction,cardiovas-cular death,fatal or non -fatal stroke during the subsequent 2 years follow -up after initial evaluation.Multiple Logis-tic regression was performed to identify the association between the characteristics of bilateral carotid arteries and cardiovascular events.Results A total of 4 413 case enrolled in the study.With carotid ultrasound,2 438 cases (55.2%)were found to be with atherosclerotic plaque formation and 235(5.3%)were with carotid artery stenosis. The proportion of single,multiple,homogeneous and heterogeneous plaques were 1 024cases(23.2%),1 114cases (32.0%),1 106cases(25.1%)and 1 333cases(30.2%),respectively.Among them,the single plaque and new cardiovascular and cerebrovascular events occured in 83 cases(P =0.168),the multiple plaques and new cardiovascular and cerebrovascular events occured in 161 cases(P <0.001 ),the homogeneous patch and new cerebral vascular events occured in 98 cases(P =0.032),the non -homogeneous patch and new cerebral vascular events occured in 146 cases(P <0.001),the stenosis and cerebral vascular events occured in 42 cases(P <0.001).Taken the new onset cardiovascular and cerebrovascular events as dependent variable,the single factor analysis showed that the carotid plaques(χ2 =14.969,P <0.001 ),and the multiple plaque(χ2 =22.509,P <0.001 ),the carotid artery stenosis (χ2 =27.561,P <0.001),the homogeneous plaque(χ2 =4.606,P <0.050),the non -homogeneous plaque(χ2 =18.301,P <0.001),the history of hypertension(χ2 =33.709,P <0.001),the high blood fat disease(χ2 =11.262, P <0.001),and the history of diabetes(χ2 =5.525,P <0.050),the coronary heart disease history(χ2 =10.440, P <0.001),the gender(χ2 =5.606,P <0.050),the smoking(χ2 =4.823,P <0.050)and the systolic blood pressure value,were all associated with the new cardio cerebral vascular events.Multivariate analysis showed that,the heterogeneous plaque(β=0.371,P <0.050),the carotid artery stenosis(β=0.621,P <0.050),the history of hypertension(β=0.517,P <0.001)and smoking(β=0.264,P <0.050)were shown to be significantly associates with new onset cardiovascular events.Conclusion The characteristics of atherosclerotic plaque of carotid artery were significantly associated with the subsequent cardiovascular events among 60 -70 years old residence in Renqiu region,Hebei.Routine carotid ultrasound screening might be useful for identify those people with high risk of develo-ping cardiovascular events.

Objective To investigate the potential relationship between neck circumference and obesity related indexes and metabolic disorders associated with insulin resistance.Methods A random cluster sampling method was used to identify study population among the 4 412 60 -70 years old permanent residents in Renqiu region.Face to face health questionnaire,physical examination,laboratory tests were used.According to the gender group,the correlation between neck circumference and obesity related indexes and metabolic disorders associated with insulin resistance were analyzed.Results Comparing neck circumference and waist circumference,waist height ratio, and body mass index(BMI) of man and woman respondents,the differences were statistically significant.Neck circum-ference and waist circumference,waist height ratio,and BMI had positive correlation(male:r =0.752,0.695 and 0.761.W:r =0.707,0.655,0.721,all P <0.01).Increased trends of neck circumference,waist circumference,waist height ratio and BMI coincided with increased trend of thypertension,diabetes,hyperlipidemia and hyperinsulinemia and hyperlipidemia,and no gender differences.With the increase of the neck circumference,the incidence of above mentioned diseases also increased accordingly.Conclusion Neck circumference was associated with obesity related indexes and metabolic disorders associated with insulin resistance.Neck circumference measurement can be used as an effective indicator of central obesity,and had great significance for early prediction and prevention of metabolic disorders associated with clinical insulin resistance.

Objective:To investigate the predictive value of pressure ulcer score and fall score and NIHSS scale for discharge outcome in patients with acute ischemic stroke (AIS).Methods:From January 2014 and November 2018, 4 468 patients with AIS who were treated in Hebei Province Renqiu Kangjixintu Hospital were selected as the research object. According to the modified Rankin scale (mRS) score standard discharge, mRS score in 0 to 2 scores was defined as good discharge outcome, and mRS score ≥3 scores defined as bad discharge outcome. Predictive value of pressure ulcer score, fall score and NIHSS score for the discharge outcome of AIS was analyzed.Results:The score of pressure ulcer in the group with bad discharge outcome was significantly lower than that in the group with good discharge outcome: (16.96 ± 2.89) scores vs. (19.91 ± 1.71) scores, the score of fall and NIHSS in the group with bad discharge outcome were higher than that in the group with good discharge outcome, with statistical significance: (6.66 ± 1.77) scores vs. (5.21 ± 1.64) scores, (7.34 ± 5.08) scores vs. (3.15 ± 2.21) scores ( P<0.01). The cutoff values of pressure sore score, fall score and NIHSS score for predicting adverse discharge outcome were 18.5, 5.5 and 3.5 scores, respectively. The area under the curve (AUC) was 0.809, 0.731 and 0.863, respectively. The sensitivity was 86.00%, 76.200% and 78.30%, and the specificity was 64.00%, 59.50% and 80.60%. The pressure ulcer score, fall score and NIHSS score had statistical difference in predicting the adverse outcome of discharge ( P<0.01). Conclusions:The pressure ulcer score, fall score and NIHSS score have good predictive value for the discharge outcome of AIS. The lower the pressure ulcer score and the higher fall score and NIHSS score are, the higher the risk of poor discharge outcome of AIS is. Actively controlling the occurrence of pressure ulcers and falls can effectively reduce the risk of poor discharge outcome of AIS.

OBJECTIVETo investigate the outcomes, survival status, and the prognostic factors of Epstein-Barr virus-associated hemophagocytic lymphohistiocytosis (EBV-HLH) patients.

METHODSA retrospective study was carried out to analyze the clinical data of 61 EBV-HLH cases, from January 2008 to July 2014. Prognostic factors were analyzed through COX model (single factor and multiple factors).

RESULTSA total of 246 patients with HLH were diagnosed, among which 102 cases were with EBV infection (including 61 EBV-HLH, 36 lymphoma associated HLH, 5 primary HLH. Among the 61 cases, 40 were male and 21 were female, with a ration of 1.9:1. The median age was 28 years (range, 12-78). 1, 3, 6 and 12-month overall survival rates of 61 EBV-HLH were 65.6%, 47.5%, 32.4%, and 25.0%, respectively. The median follow-up time was 3 (0.5-28) months. 12 patients didn't use etoposide within 4 weeks after diagnosis, while HLH-94 protocol was used in 33 patients and HLH-2004 protocol was used in 16 patients. Response rates of theses three groups were 33.3%, 51.5%, and 43.8%, respectively (P=0.401). There was statistically difference between the group without etoposide and the HLH-94/ HLH-2004 group in the overall survival rate (P=0.033). Serum albumin level (P=0.033) and whether EBV could became negative (P=0.010) were independent predictors for EBV-HLH.

CONCLUSIONEBV-HLH patients have severe clinical feature and poor prognosis. Early application of immune chemotherapy based on etoposide can improve survival. Serum albumin level and whether EBV can become negative are independent prognostic factors for survival.
