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 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 intramedullary nailing assisted by minimally invasive cerclage with simple intramedullary nailing in the treatment of femoral long oblique subtrochanteric fractures.Methods From April 2010 to September 2015,our department treated 39 patients with femoral long oblique subtrochanteric fracture.Of them,16 were treated by cephalomedullary nailing combined with minimally invasive cerclage (observation group of 11 males and 5 females with an average age of 42.8 ± 13.2 years) and 23 by simple cephalomedullary nailing (control group of 17 males and 6 females with an average age of 46.2 ± 10.1 years).Their operation time,intraoperative blood loss,radiologic results (union time and alignment) and functional results [Visual Analog Scale (VAS) and Harris hip score] were compared between the 2 groups.Results The 39 patients were followed up from 12 to 30 months (average,15 months).For the observation group,the varus angle (2.2°± 1.4°) was significantly smaller than for the control group(4.1°±2.2°),the VAS scores at 1 and 3 months postoperatively (3.43 ± 1.54,1.13 ± 1.20) were significantly lower than for the control group (5.61 ± 1.41,3.34 ± 1.82),and the clinical union ratio at 3 months postoperatively(87.5％,14/16) significantly higher than for the control group (47.8％,11/23) (P ＜ 0.05).There were no significant differences between the 2 groups in terms of operation time,intraoperative blood loss,Harris hip score at one year postoperatively,VAS score at 6 months postoperatively,or clinical union ratio at 6 or 12 months postoperatively(P ＞ 0.05).Conclusions Cephalomedullary nailing is effective for the treatment of femoral long oblique subtrochanteric fractures no matter it is assisted by minimally invasive cerclage or not.However,since minimally invasive cerclage has the advantage of improving reduction and mechanical stability,combination of minimally invasive cerclage and cephalomedullary nailing may be more advantageous in early pain-relieving and functional recovery.

Objective To evaluate the effects of andrographolide on insulin resistance,dysbiosis and Notch/zinc finger protein transcription factor 1(Snail1)signaling pathway in diabetic rats.Methods A total of 70 male Wistar rats with SPF grade were selected,and 30 of them were selected for andrographolide LD50 test.After determining the lethal dose,50 mg/kg was selected for administration and observation,the remaining 40 rats,10 were used as the NC group,30 were established as the diabetes model,and a total of 28 rats were successfully modeled,which were divided into T2DM group(n=9),Metformin treatment group(Met,n=9),and andrographolide administration group(And,n=10).The NC group and T2DM group were not treated.The changes were evaluated after 14 days of intervention.Results Compared with NC group,HOMA-IR,the abundance levels of Bacteroidetes,Firmicute,mRNA and protein expression levels of Notch and Snail1,and positive expression rates were increased(P<0.05),while the abundance levels of Lactobacillus and Bifidobacterium were decreased in T2DM,Met and And group(P<0.05).Compared with T2DM group,HOMA-IR,the abundance levels of Bacteroidetes,Firmicute,mRNA and protein expression levels of Notch and Snail1,and positive expression rates were decreased,while the abundance levels of Lactobacillus and bifidobacterium were increased in Met and And group(P<0.05).Conclusions After andrographolide intervention,insulin resistance was alleviated,microbiota imbalance was improved,and Notch/Snail1 signaling pathway was suppressed in diabetic rats.

Objective To investigate the effect of atractylenolide Ⅲ(A Ⅲ)on stroke in spon-taneously hypertensive rats by regulating microRNA-296-5p(miR-296-5p)expression.Methods The spontaneously hypertensive rats(SHR)were given 0.9％sodium chloride solution freely for 2 months,and then fed with 1％sodium chloride solution to establish the stroke model of SHR.The rat models were randomly grouped into Model group,A Ⅲ low-dose group(A Ⅲ-L group),A Ⅲ high-dose group(A Ⅲ-H group),positive drug nimodipine group(Nim group),miR-296-5p agonist group(miR-296-5p agomir group),agomir NC group,A Ⅲ-H+miR-296-5p agomir group,and A Ⅲ-H+agomir NC group,with 12 in each group.The changes in neurological symptom scores,av-erage arterial pressure,survival time,and platelet adhesion rate were detected and recorded;hema-toxylin and eosin(HE)staining was applied to detect pathological changes in the CA1 region of the rat hippocampus;quantitative reverse transcription polymerase chain reaction(qRT-PCR)was ap-plied to detect the expression of miR-296-5p in the hippocampal CA1 region.Results Compared with the NC group,the Model group showed increases in neurological symptom score,mean arterial pressure,platelet adhesion rate,miR-296-5p expression,shortened survival time,and severe pathological damage to the hippocampal CA1 area(P＜0.05);compared with the Model group,the neurological symptom scores,mean arterial pressure,platelet adhesion rate,and miR-296-5p expression in the A Ⅲ-L,A Ⅲ-H,and Nim groups decreased,the survival time was prolonged,and the pathological damage in the CA1 area of the hippocampus was alleviated(P＜0.05);compared with Model group and agomir NC group,neurological symptom score,mean arterial pressure,platelet adhesion rate and miR-296-5p expression of rats in the miR-296-5p agomir group were increased,survival time was shortened,and pathological damage in hippocampal CA1 region was aggravated(P＜0.05).compared with the A Ⅲ-H group and the AⅢ-H+agomir NC group,the neurological symptom score,average arterial pressure,platelet adhesion rate and miR-296-5p expression of rats were in-creased,the survival time was shortened,and the pathological damage in hippocampal CA1 region was serious in the AⅢ-H+miR-296-5p agomir group(P＜0.05).Conclusion A Ⅲ may treat SHR stroke by inhibiting the expression of miR-296-5p.

Objective:To compare the complications associated with various urinary flow diversion methods and identify the factors that contribute to the decline in renal function after radical total cystectomy for myoinfiltrating urothelial carcinoma.Methods:This study conducted a retrospective analysis on the clinical data of 46 patients with pathologically confirmed muscle-invasive bladder cancer.The patients underwent laparoscopic radical cystectomy with either ileal conduit diversion(n=21)or ureterocutaneous diversion(n=25)between January 2017 and December 2021.Perioperative data, postoperative pathology, postoperative complications, and follow-up results were compared between the two groups.Results:The study found significant differences between the two groups in terms of age[(67±6)years vs.(73±8)years, t=3.132, P=0.003], Charlson comorbidity index adjusted for age[(3.80±1.15) vs.(4.52±1.03), t=2.223, P=0.031], prognostic nutritional index[(48.81±5.74) vs.(43.64±4.74), t=3.347, P=0.002], operation time[(449±108)minutes vs.(326±130)minutes, P=0.001]], hospital stay[(20.1±11.1)days vs.(13.3±5.2)days, t=2.762, P=0.008], proportion of Clavien grade 3 or higher complications within 3 months after surgery(4/21 vs 0/25, χ2=2.105, P<0.05), and proportion of stoma-free patients(18/21 vs.5/25, χ2=6.373, P<0.01). According to Logistic multivariate analysis, perioperative blood transfusion and urinary tract infection were identified as independent risk factors for renal function decline 12 months after surgery.Escherichia coli was found to be the most common bacteria cultured from urinary tract infections in both groups after surgery. Conclusions:Laparoscopic radical cystectomy with ureterocutaneous diversion offers benefits such as shorter hospital stays and fewer perioperative complications for older and frail patients.However, a higher proportion of patients may require ureteral stenting.It is important to note that perioperative blood transfusion and urinary tract infection are major risk factors for renal function decline following radical cystectomy.
