AIM: This study was designed to investigate the effects of sodium restriction and sodium supplementation on the expression of angiotensinogen mRNA in myocardium of rats with congestive heart failure(CHF).METHODS: Radioimmunassay and in situ hybridization techniques were used to determine the angiotensin Ⅱ(AngⅡ)contents and the expression of angiotensinogen(ANG)mRNA in myocardium, respectively.RESULTS: In sodium restricted group, the plasma sodium was obviously lower than that in CHF group(P

AIM: To investigate the expression of angiotensinogen (ANG)mRNA and the changes of AngⅡ content in rat anterior pituitary during acute stress.METHODS: The expression of ANG mRNA was determined using in situ hybridization technique, and the AngⅡ content were determined by RIA.RESULTS: The ANG mRNA expression and AngⅡ content were significantly increased, and ANG mRNA was increased more significantly than AngⅡ content. CONCLUSION: The local renin-angiotensin system (RAS) in anterior pituitary is obviously activated during stress, which strongly supports the view that local RAS contributes to stress reaction.

Objective:To identify the risk factors for decrease in regional cerebral oxygen saturation (rScO 2) during one-lung ventilation (OLV) in the patients undergoing thoracic surgery. Methods:A total of 175 patients of both sexes, aged ≥55 yr, with expected operation time≥2 h, scheduled for elective thoracic surgery with OLV, were selected in the Fourth Hospital of Hebei Medical University from August 2017 to September 2018.The rScO 2 was continuously monitored from the beginning of anesthesia induction until removal of tracheal intubation.General anesthesia, general anesthesia combined with epidural block or general anesthesia combined with local nerve block were used.The baseline characteristics, previous medical history and history of anesthesia surgery, type of surgery, method of anesthesia, duration of anesthesia, duration of OLV, duration of surgery, and intraoperative adverse events (hypoxemia, hypotension, bradycardia, etc.) were recorded.According to whether a decrease in rScO 2 occurred during OLV (absolute value of rScO 2 was less than 65% or a decrease of more than 20% of the baseline value), the patients were divided into 2 groups: low rScO 2 group and normal rScO 2 group.Multivariate logistic regression analysis was used to identify the risk factors for decrease in rScO 2 during OLV. Results:One hundred and seven patients developed decrease in rScO 2 during OLV, with an incidence of 61.1%.The results of logistic regression analysis showed that hypoxemia was an independent risk factor for decrease in rScO 2, and general anesthesia combined with epidural block was a protective factor for decrease in rScO 2 during OLV. Conclusion:Hypoxemia is an independent risk factor for decrease in rScO 2 during OLV, while general anesthesia combined with epidural block is a protective factor for decrease in rScO 2 in the patients undergoing thoracic surgery.

ObjectiveTo investigate the effect of daily soft brace wearing on plantar dynamics during walking in patients with chronic ankle instability (CAI). MethodsA total of 52 patients with unilateral chronic ankle instability (CAI) in Beijing Rehabilitation Hospital from February, 2021 to January, 2023 were randomly divided into control group (n = 26) and experimental group (n = 26). Both groups underwent an eight-week exercise training program. The control group wore placebo brace during daily activities, while the experimental group wore soft ankle brace. Plantar dynamic parameters were measured using a pressure plate system during walking, including peak plantar pressure and plantar impulse before and after intervention. ResultsSix participants dropped out in the control group and five in the experimental group, resulting in a final inclusion of 41 participants. After intervention, there was no significant difference in peak plantar pressure and impulse on the affected side in the control group among different areas (P > 0.05). In the experimental group, the peak pressure and impulse in the heel medial, heel lateral and forefoot medial areas increased (|t| > 4.192, P < 0.001), while the peak pressure and impulse in the midfoot and lateral forefoot areas decreased (t > 2.984, P < 0.05); the peak pressure and impulse in the heel medial, heel lateral and forefoot medial areas were higher in the experimental group than in the control group (|t| > 2.126, P < 0.05), and the peak pressure and impulse were lower in the midfoot and forefoot lateral areas (t > 2.133, P < 0.05). ConclusionWearing a soft brace during daily activities may optimize the distribution of peak plantar pressure and plantar impulse on the affected side in patients with CAI, which may prevent recurrence of sprains.

ObjectiveTo investigate the association between metabolic associated fatty liver disease （MAFLD） and carotid atherosclerotic plaque. MethodsA total of 1 107 patients who were hospitalized in The Second Affiliated Hospital of Kunming Medical University from July， 2014 to December， 2022 were enrolled， and all patients underwent abdominal ultrasound and CT angiography of the head and neck arteries. Baseline data and clinical diagnosis were collected， and the patients were divided into MAFLD group with 499 patients and non-MAFLD group with 608 patients based on medical history， clinical tests， and imaging findings. According to the CT value， carotid plaques were classified into calcified plaques， non-calcified plaques， and mixed plaques. According to the NASCET criteria， carotid stenosis was categorized as normal vessel， slight stenosis， mild stenosis， moderate stenosis， and severe stenosis/occlusion. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U rank sum test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test was used for comparison of categorical data between two groups. Univariate and multivariate Logistic regression analyses were used to investigate the influencing factors for carotid atherosclerosis. ResultsCompared with the non-MAFLD group， the MAFLD group had a significantly higher proportion of patients with calcified plaques （74.3% vs 63.3%， P<0.05）， non-calcified plaques （27.1% vs 17.1%， P<0.05）， or mixed plaques （27.3% vs 20.7%， P<0.05）， as well as a significantly higher proportion of patients with mild stenosis （50.9% vs 44.9%， P<0.05）， moderate stenosis （14.6% vs 8.4%， P<0.05）， or severe stenosis/occlusion （6.6% vs 3.5%， P<0.05）. The univariate logistic regression analysis showed that MAFLD was a risk factor for calcified carotid plaques， non-calcified plaques， and mixed plaques， and it was also a risk factor for mild stenosis， moderate stenosis， and severe stenosis/occlusion of the carotid artery （all P<0.05）. After adjustment for confounding factors， the multivariate Logistic regression analysis showed that MAFLD was an independent risk factor for calcified plaque， non-calcified plaque， mixed plaque， and moderate stenosis of the carotid arteries （all P<0.05）. ConclusionMAFLD is an independent risk factor for moderate stenosis， calcified plaques， non-calcified plaques， and mixed plaques of the carotid arteries.

ObjectiveTo investigate the influence of different diagnostic criteria on the short-term prognosis of patients with acute-on-chronic liver failure （ACLF）. MethodsA total of 115 ACLF patients who were hospitalized in Department of Gastroenterology， The Second Affiliated Hospital of Kunming Medical University， from January 2018 to January 2022 were enrolled， and all patients received internal medical treatment combined with artificial liver therapy. According to the guidelines， the patients were divided into CMA guideline group （Diagnostic and treatment guidelines for liver failure by Chinese Medical Association）（n=100）， APASL guideline group （Consensus statements of Asian Pacific Association for the Study of the Liver）（n=94）， and EASL guideline group （Criteria proposed by European Association for the Study of the Liver）（n=36）. The above three guidelines were compared in terms of 90-day mortality rate. A one-way analysis of variance was used for comprision of continuous date between groups； the chi-square test was used for comprision of categorical date between groups. The receiver operating characteristic （ROC） curve of related variables. ResultsThe 90-day mortality rate was 50.0% in the CMA guideline group， 51.1% in the APASL guideline group， and 77.8% in the EASL guideline group， and the EASL guideline group had a significantly higher 90-day mortality rate than the CMA guideline group （χ²=8.351， P=0.004） and the APASL guideline group （χ²=7.650， P=0.006）. EASL guideline had a sensitivity of 22.2% and a specificity of 92.3% in predicting the risk of short-term mortality， with an area under the ROC curve was 0.576. ConclusionACLF patients who meet EASL guideline tend to have a worse short-term prognosis， and this guideline may help to identify patients at a relatively high risk of short-term death.
