To investigate the interrelationship between plasma renin activity(PRAXaldosterone (Ald),atrial natri-uretic peptide ( ANP ) and blood volume ( BV ) in adult nephrotic syndrome ( NS ) . Methods BV was assessed using 113mInCl dilution method. PRA、 Angiotensin Ⅱ (AngⅡ)、Ald、ANP were determined by radioirnmunoassay. 28 edema-tous NS patients,26 healthy controls and 18 cases of remission were involved. Results (1)During edematous period, PR, AngⅡ , Ald、 ANP were higher in NS than in controls. There was no difference of BV between NS and controls. Albumin ,PRA,AngⅡ 、Ald and ANP were not correlated with BV; (2)After remission, comparing with edematous period, Ald 、ANP deceased significantly whereas PRA、AngⅡ、Ald and total BV were not different; (3) Urine natrium excretion (UNaV) was negatively correlated with Aid. Conclusion Ald and ANP may be the major regulating factors of sodium excretion in nephrotic syndrome.

Objective:
To investigate the prevalence of daily smoking among residents at ages of 15 years and older in Wuhan City, so as to provide insights into tobacco control.
Methods:
A total of 2 700 permanent residents at ages of 15 years and older were sampled using a multistage random sampling method in three districts of Wuhan City in July, 2019. Residents' demographics, tobacco use, secondhand smoke exposure and awareness of harmful effects of tobacco were collected using the core questionnaire of the Global Adult Tobacco Survey, and the factors affecting daily smoking were identified among residents at ages of 15 years and older using a multivariable logistic regression model.
Results:
A total of 2 700 questionnaires were allocated, and 2 551 valid questionnaires were recovered, with an effective recovery rate of 94.48%. The respondents included 1 272 men (49.86%) and 1 279 women (50.14%), and the proportion of daily smoking was 19.84% among the respondents, with a mean daily tobacco use of 16.6 cigarettes. Multivariable logistic regression analysis identified men (OR=66.191, 95%CI: 25.344-172.873), ages of 45 to 64 years (OR=2.586, 95%CI: 1.158-5.775), farmers (OR =8.477, 95%CI: 1.126-63.786), secondhand smoke exposure at home (OR=9.395, 95%CI: 5.401-16.340), secondhand smoke exposure in workplaces (OR=1.923, 95%CI: 1.081-3.423) and no smoking at home (OR=0.459, 95%CI: 0.277-0.763) as factors affecting daily smoking among residents at ages of 15 years and older in Wuhan City.
Conclusions
There is a high likelihood of daily smoking among men, the middle-aged and elderly, farmers and individuals with exposure to secondhand smoke in workplaces at ages of 15 years and older in Wuhan City. Health education pertaining to tobacco control requires to be reinforced among high-risk populations, and creation of a tobacco-free home is recommended in public places and workplaces based on the complete smoking ban.

BACKGROUND: Neurological complications after coronary artery bypass grafting still have a high incidence rate, and the etiology is multiple.OBJECTIVE: To retrospectively investigate the occurrence and relevant factors of severe neurological complications after coronary artery bypass grafting (CABG).METHODS: A total of 761 consecutive patients with undergoing CABG were included in this study from September 2002 to August 2009 at the Nanjing Drumtower Hospital, including 443 males and 318 females, aged from 32-89 years. All patients were grouped according to age(more than or less than 70-year-old) and on pump or off pump coronary surgery. Disclose the relationship between the risk factors and the neurological complications by statistics analysis.RESULTS AND CONCLUSION: Totally 41 patients had serious neurological complications in this study. There was a higher complication incidence in 570-year-old group patients (n=22) than < 70-year-old group (n=19)(14.9% vs. 3.1%, P< 0.001). The neurological complications incidence was similar in on-Pump CABG group (n =7) and off-Pump CABG group (n = 34) (5.3% vs.5.4%, P=0.39). The incidence rate of severe neurological complications was high in carotid artery stenosis > 50% patients. A total of 8 cases died, 2 for massive hemorrhage of gastrointestinal tract; 1 for severe sepsis; 4 for multiple organ dysfunction syndrome;1 for epilepsia gravior postoperatively. Finally, 33 cases survived. The average time of follow up was 3 years, 3 cases died, 3 cases recovery from limitation of limb or hand movement partly, and 1 case had severe mental retardation. Results displayed that elderly patients(= 70 years) undergoing CABG are at higher risk of neurological dysfunction. Carotid artery stenosis is the most risk factor. There are no significant effects on postoperative complications between on-pump CABG and off-pump CABG.
