Objective To investigate the correlation of the supine hypertension (SP) with carotid intima-media thickness (IMT) in the elderly. Methods Kailuan study is a functional community-based cardiovascular risk factor study. From June 2006, there was a physical examination every two years. In the examination, demographic data, smoking, drinking, physical exercise situation and medication situation were recorded. Levels of triglyceride, high sensitivity C-reactive protein, low density lipoprotein and other biochemical indexes were observed. Using cluster random sampling, 3 064 retired employees of 60 years of age or older were selected. A total of 2 464 subjects took part in an additional examination, including the 24-hour ambulatory blood pressure monitoring, brachial-ankle pulse wave velocity, blood pressure of different positions and urine albumin. Multiple linear regression was used to analyze the correlation between supine systolic blood pressure (SBP) and IMT. Multivariate Logistic regression was used to analyze the effect of SP on IMT. Results (1) Among 2 220 participants (67.29±6.09) years, 1 463 (65.9%) individuals were male and 757 (34.1%) were females, and the average IMT was (0.92 ± 0.18) mm. (2) There was a positive correlation between supine SBP and IMT (r=0.175, P<0.01). (3) After adjusting the confounds, supine SBP was significantly associated with IMT, with an increase of 1 SD (+20.42 mmHg, 1 mmHg=0.133 kPa) in SBP corresponding to an increase of IMT by 0.01 mm (P<0.01). (4) Multiple Logistic regression analysis showed that after adjusting for sitting SBP, age, gender and other factors, SP was still a risk factor of increased IMT (OR=1.37, 95%CI:1.03-1.80), and independent of sitting SBP. Conclusion The supine hypertension is a risk factor of increased IMT, and independent of sitting SBP.

Objective To evaluate the clinical effect of ultrasound - guided sclerosing agent lauromacrogol injection in treating lymph leakage. Methods A total of 31 patients with postoperative lymph leakage were selected for this study. Of the 31 patients, successful conservative oppression treatment was accomplished in 16, and lauromacrogol injection had to be carried out in 15 as conservative oppression treatment failed. The patients were followed up and the results were analyzed. Results In 15 patients receiving lauromacrogol injection treatment, complete cure of lymph leak was obtained in 14 with a success rate of 93.33%. Among the 14 cases, the second lauromacrogol injection was employed in 3 at one week after the first injection. Infection occurred in another case one day after the injection , which was cured after dressing change for 15 days. Conclusion For the treatment of lymph leakage, ultrasound-guided sclerosing agent lauromacrogol injection is effective and safe.

Objective To investigate the correlation of short-term systolic blood pressure variability (SBPV) with esti?mated glomeruar filtration rate (eGFR) in the elderly. Methods In physical examination for the third time of kailuan group, the method of cluster sampling was used to collect randomly retired employees, age≥60 in kailuan group. The 24-hour am?bulatory blood pressure monitoring was given to these objects. Finally, 1 405 participants with integral data were recruited in?to the survey. SBPV indices were standard deviation of systolic blood pressure (SD), variability independent of the mean (VIM), maximum-minimum difference (MMD), and average real variability (ARV). Multivariate stepwise linear regression models were used to analyze the influence of short-term SBPV on eGFR. Results (1) Among 1 405 participants (67.16 ± 5.82) years, 933 individuals (66.4%) were male and 472 (33.6%) were female. (2) Study population were divided into four groups based on the 24-hour mean SBP, daytime mean SBP, night time mean SBP (group 1:mean SBP<120 mmHg, group 2:120≤mean SBP<140 mmHg, group 3:140≤mean SBP<160 mmHg, group 4:mean SBP≥160 mmHg), respectively. Values of SD, MMD and ARV, but not VIM were increased with increased mean SBP. (3) The participants were grouped according to the median SBPV with between-group comparison of the eGFR. The average eGFR levels were lower in the high 24-hour SB?PV group (SD, VIM, MMD and ARV), day-time SBPV group (SD, VIM, MMD and ARV) and night-time SBPV group (SD, MMD and ARV) than those in the low SBPV groups (P<0.05). (4) Multivariate stepwise linear regression showed that eGFR increased with 3 indices of 24-hour SBPV (SD, MMD and ARV) and 2 indices of day-time SBPV (MMD and ARV) but not for night-time SBPV (β=-0.07,-0.11,-0.07,-0.12 and-0.07, respectively). Conclusion There is a certain degree of asso?ciation between short-term SBPV indices and eGFR.

OBJECTIVE: To compare the therapeutic effect of radiofrequency ablation and focused ultrasound in treatment of allergic rhinitis which was refractory to medical therapy, and to explore the reliable and safe surgical treatment. METHOD: Eighty-six perennial allergic rhinitis patients were divided randomly into two group. The radiofrequency ablation group included 40 patients and focused ultrasound group included 46 patients. A standard 0 to 10 visual analog scale (VAS) was used to assess the allergic symptoms therapeutic effect before and one year after treatment. RESULT: Allergic symptoms were improved in both two groups one year after treatment. The total VAS score in radiofrequency ablation group decreased from 31.35 +/- 6.16 to 14.16 +/- 4.83 and the total effective power of this group was 87.5% at the twelfth month after surgical. While the total VAS score in focused ultrasound group decreased from 32.86 +/- 5.45 to 21.91 +/- 8.58 and total effective power was 69.6% (all P < 0.01). CONCLUSION This study had demonstrated that the radiofrequency ablation and focused ultrasound appears to be an effective and safe tool for treating allergic rhinitis which was refractory to medical therapy. Compared to focused ultrasound, the radiofrequency ablation seemed to have a longer time therapeutical effect. While the focused ultrasound was more safe and little trauma, which made it possible to the repeated application.

Objective:To explore the risk factors of hypotension in patients with hemodialysis-related superior vena cava diseases.Methods:This was a retrospective cohort study. The maintenance hemodialysis patients diagnosed as superior vena cava stenosis ≥50% or occlusion in West China Hospital of Sichuan University from January 1, 2019 to March 31, 2022 were selected. The patients were divided into hypotensive group and non-hypotensive group according to the occurrence of hypotension during non-dialysis period. The differences of general clinical data, cardiac ultrasound parameters and blood biochemical indexes between the two groups were compared. Multivariate logistic regression model was used to analyze the risk factors of hypotension in patients with hemodialysis-related superior vena cava lesions.Results:A total of 202 patients with hemodialysis-related superior vena cava lesions were included, of whom 84 patients (41.6%) developed hypotension during non-dialysis. Compared with the non-hypotensive group, patients in the hypotensive group had longer dialysis age ( Z=2.093, P=0.036), shorter left atrial diameter ( t=2.316, P=0.022), lower aortic valve orifice flow rate ( t=3.702, P=0.001) and serum calcium ( t=2.320, P=0.021), thicker left ventricular posterior wall ( t=3.042, P=0.003), lower proportions of hypertension history ( χ2=9.125, P=0.003), and higher proportion of residual superior vena cava ≤30% or occlusion ( χ2=8.940, P=0.003) and azygous vein opening ( χ2=11.067, P=0.001). Multivariate logistic regression analysis results showed that no history of hypertension ( OR=0.383, 95% CI 0.156-0.943, P=0.037), slow aortic valve orifice flow ( OR=0.207, 95% CI 0.062-0.695, P=0.011) and low blood calcium ( OR=0.236, 95% CI 0.066-0.841, P=0.026) were the independent influencing factors of hypotension in patients with hemodialysis-related superior vena cava diseases. Conclusions:Hemodialysis patients with severe stenosis or occlusion of the superior vena cava during non-dialysis have a higher risk of hypotension. No history of hypertension, slow aortic valve orifice flow, and low blood calcium are the independent risk factors of hypotension in patients with hemodialysis-related superior vena cava diseases.

OBJECTIVETo explore the impact of ideal health behaviors on the newly developed carotid plaques.

METHODSA total of 5 852 employees (including retired employees from Tangshan Kailuan company) aged over 40 years were included in this study through stratified random sampling. Subjects with previous stroke, transient ischemic attack, myocardial infarction were excluded. Results from the unified questionnaire, blood biochemistry measurements and ultrasonography carotid artery measurements were analyzed. Present study analyzed the data from 2 372 participants without carotid plaques in 2010-2011 examinations. The newly developed carotid plaques in 2012-2013 health examinations were observed and multiple logistic regression analysis was used to explore the impact of ideal health behaviors and factors on the newly developed carotid plaques.

RESULTS(1) There were 359 subjects with newly developed carotid artery plaques among the 2 372 subjects (15.1%), prevalence rate was 23.1% (43/186), 17.5% (186/1 065), 12.4% (122/986), 5.9% (8/135) in the groups with 0-1, 2-3, 4-5 and 6-7 components of ideal cardiovascular health behaviors and factors, respectively (P < 0.001). (2) Multiple logistic regression analysis showed that after adjusting for age, gender, high density lipoprotein cholesterol, heart rate, and high sensitive c-reactive protein, compared to with 0-1 components of ideal cardiovascular health behaviors and factors, participants with 4-5 and 6-7 components of ideal cardiovascular health behaviors and factors were associated with reduced risk of the newly developed carotid plaques, the OR (95% CI) values were 0.52(0.34-0.80) and 0.28(0.12-0.64), respectively.

CONCLUSIONHigher number of ideal cardiovascular health behaviors and factors is associated with lower incidence of newly developed carotid plaques.
