BACKGROUND

Blood pressure is an important vital sign measured not only in hypertension but also among hospitalized patients for clinical evaluation of the actual hemodynamic status. In the digital era, mercury and aneroid sphygmomanometers are being replaced by automated monitors despite lacking validation and recommendations for their use, especially in acute illness.

To compare automated and manual blood pressure measurement among hospitalized medical patients with acute illness.

A crossover design was used in a single tertiary hospital. Blood pressure was recorded from 216 participants, with 432 observations from an automated monitor (Omron HBP1120) and a mercury sphygmomanometer. Automated and manual BP recordings were done twice following the same arm sequential method. The average of the two recordings was used for comparison.

Most participants were female, elderly, obese, and had cardiac complaints. Comparing automated and manual methods, the mean difference for systolic was 1.47 ± 12.12 (p = 0.08) and 1.82 ± 10.99 (p=0.02) for diastolic. Subgroup analysis revealed that males had higher manual systolic BP than females (pairwise p-value= 0.017). Overweight and obese participants had higher automated systolic and diastolic BP (p=0.04). Overweight and obese participants had significantly higher systolic and diastolic BP regardless of the method. Significantly higher diastolic BP for different age groups and areas of admission (p=0.02) were observed from the automated method.

Automated BP monitoring showed a significant difference in diastolic BP recordings. Automated BP monitors should be used with caution, especially in interpreting diastolic BP among hospitalized patients.

It has been found that the incidence of cardiovascular disease in patients with lower limb amputation is significantly higher than that in normal people, and the risk of developing coronary atherosclerosis is much higher than that in other high-risk groups. Numerous studies have confirmed that high systolic and diastolic blood pressures are potential risk factors for coronary artery disease, and it has been demonstrated that the ascending aortic pressure during diastole increases after amputation. However, the relationship between lower limb amputation and coronary atherosclerosis has not been fully explained from the perspective of hemodynamic environment. Therefore, in this study, a centralized parameter model of the human cardiovascular system and a three-dimensional model of the left coronary artery were established to investigate the effect of amputation on the hemodynamic environment of the coronary artery. The results showed that the abnormal hemodynamic environment induced by amputation, characterized by factors such as increased diastolic pressure in the ascending aorta, led to a significant expansion of the low wall shear stress (WSS) region on the outer lateral aspect of the left coronary artery bifurcation during diastole. The maximum observed increase in the area of low WSS reached up to 50.5%. This abnormal hemodynamic environment elevates the risk of plaque formation in the left coronary artery. Moreover, the more severe the lower limb atrophy, the greater the risk of coronary atherosclerosis in amputees. This study preliminarily reveals the effect of lower limb amputation on the hemodynamic environment of the left coronary artery.

The central amygdala (CeA) is a crucial modulator of emotional, behavioral, and autonomic functions, including cardiovascular responses. Despite its importance, the specific circuit by which the CeA modulates blood pressure remains insufficiently explored. Our investigations demonstrate that photostimulation of GABAergic neurons in the centromedial amygdala (CeM^GABA), as opposed to those in the centrolateral amygdala (CeL), produces a depressor response in both anesthetized and freely-moving mice. In addition, activation of CeM^GABA axonal terminals projecting to the nucleus tractus solitarius (NTS) significantly reduces blood pressure. These CeM^GABA neurons form synaptic connections with NTS neurons, allowing for the modulation of cardiovascular responses by influencing the caudal or rostral ventrolateral medulla. Furthermore, CeM^GABA neurons targeting the NTS receive dense inputs from the CeL. Consequently, stimulation of CeM^GABA neurons elicits hypotension through the CeM-NTS circuit, offering deeper insights into the cardiovascular responses associated with emotions and behaviors.

OBJECTIVE: To observe the effects of Yisui Yangxin moxibustion (moxibustion for benefiting the marrow and nourishing the heart) in sequential trial on blood pressure (BP), perimenopausal symptoms, cardiovascular function and heart rate variability (HRV) in prehypertension in perimenopausal women. METHODS: The eligible female patients of prehypertension of perimenopausal period were collected according to the inclusion criteria. Based on the requirements of open two-way qualitative response sequential trial, the sample size was not set in advance, and the matched pair design was used for random division into a moxibustion group and a health education group. The patients of the two groups were treated in pairs, and the analysis was immediately performed after the end of treatment for each pair, and the sequential trial analysis (STA) was diagrammed. The health education group provided the health education for prehypertension to the patients according to 2018 Revised Chinese Hypertension Prevention and Treatment Guidelines. In the moxibustion group, beside the health education for prehypertension, the non-suppurative moxibustion was delivered at Baihui (GV20), Guanyuan (CV4) and bilateral Neiguan (PC6) and Zusanli (ST36), once every two days, 3 treatments per week and for 4 consecutive weeks. Before treatment, in 2 and 4 weeks of treatment, as well as in 1-month follow-up after treatment, BP was measured in each group, separately. Before treatment and in 4 weeks of treatment, the observation was performed in the score of the modified Kupperman scale, and Pittsburgh sleep quality index (PSQI) score, the indexes of cardiovascular function (stroke volume [SV], cardiac output per minute [CO], stroke index [SI], cardiac index [CI], left ventricular effective pumping force [VPE], left ventricular energy efficiency [EWK], arterial compliance [AC], left ventricular ejection resistance [VER], blood viscosity (N), and microcirculation half update rate [MHR]), and heart rate variability (HRV) indexes (low frequency [LF], high frequency [HF], LF/HF, standard deviation of NN interval [SDNN], root mean square of successive differences in adjacent NN intervals [RMSSD]). RESULTS: Based on sequential test line, when the trial was performed to the 17th pair, and the test line touched the upper limit U, meaning the results of the moxibustion group was superior to the health education group, thus, the trial stopped immediately. In 2 and 4 weeks of treatment and in follow-up, the systolic blood pressure (SBP) and diastolic blood pressure (DBP) were lower when compared with those before treatment in the moxibustion group (P<0.05); SBP at each time point and DBP in 2 and 4 weeks of treatment in the moxibustion group were lower than those of the health education group (P<0.05). After treatment, the score of the modified Kupperman scale was reduced when compared with that before treatment in the moxibustion group (P<0.05). The score of the modified Kupperman scale and PSQI in the moxibustion group were lower than those of the health education group after treatment (P<0.05). After treatment, SV, CO, SI, CI and EWK were increased in comparison with the indexes before treatment in the moxibustion group (P<0.05), and VER and N were dropped (P<0.05). After treatment, SV, CO, SI, CI and EWK in the moxibustion group were higher than those of the health education group (P<0.05), and VER and N were lower (P<0.05). After treatment, in the moxibustion group, LF, HF, SDNN and RMSSD were increased in comparison with those before treatment (P<0.05), and LF/HF was declined (P<0.05). In the health education group, after treatment, LF, HF, SDNN and RMSSD decreased when compared with those before treatment (P<0.05). After treatment, LF, HF, SDNN and RMSSD in the moxibustion group were higher than those of the health education group (P<0.05), and LF/HF was lower (P<0.05). The total effective rate was 94.1% (16/17) in the moxibustion group, higher than that (41.2%, 7/17) in the health education group (P<0.05). CONCLUSION Moxibustion can reduce SBP and DBP in prehypertension of perimenopausal women, alleviate perimenopausal symptoms, improve cardiac function and adjust the overall balance of cardiac autonomic nerves.

OBJECTIVE: To compare the clinical efficacy of acupuncture with Neiguan (PC6)-to-Waiguan (TE5) and esmolol on hemodynamics during anesthesia induction and postoperative nausea and vomiting. METHODS: A total of 100 patients undergoing elective laparoscopic hernia repair or gynecological surgery under general anesthesia were randomly divided into an acupuncture group (50 cases, 3 cases were eliminated) and an esmolol group (50 cases, 2 cases were eliminated). In the acupuncture group, before anesthesia induction, patients were applied to acupuncture with Neiguan (PC6)-to-Waiguan (TE5), and the needles were retained for 15 min on the right side and 30 min on the left side. Patients in the esmolol group were intravenously injected with 20 mg esmolol hydrochloride injection 5 min before anesthesia induction. The systolic blood pressure (SBP) and heart rate (HR) of the two groups were recorded at 5 min after entering the operating room (T₀), before anesthesia induction (T₁), after anesthesia induction (T₂), before tracheal intubation (T₃) and 1 min after tracheal intubation (T₄). The visual analogue scale (VAS) scores of pain and the incidence of nausea and vomiting in the two groups were observed at the time of entering postanesthesia care unit (PACU) (T₅), leaving PACU (T₆), 6 h after operation (T₇) and 24 h after operation (T₈). The dosage of anesthesia-related drugs in the two groups was counted. RESULTS: The SBP and HR of the two groups at T₂, T₃ and T₄ were lower than those at T₁ (P<0.05). SBP and HR at T₃ in the acupuncture group were higher than those in the esmolol group (P<0.05). Compared with the esmolol group, in the acupuncture group, the VAS scores of pain at T₆ and T₇ were decreased (P<0.05), the incidence of nausea and vomiting at T₇ and T₈ and the nausea and vomiting visual analogue scale (NVAS) scores were decreased (P<0.05). Compared with the esmolol group, the dosage of propofol in the acupuncture group was decreased (P<0.05). CONCLUSION Acupuncture with Neiguan (PC6)-to-Waiguan (TE5) can relieve hemodynamic fluctuations during anesthesia induction, reduce postoperative pain and nausea and vomiting, and reduce the dosage of propofol. The curative effect is better than that of esmolol.

OBJECTIVE: To observe the clinical efficacy of acupoint magnetotherapy as an adjunctive treatment for mild to moderate hypertension with yin deficiency and yang hyperactivity. METHODS: A total of 66 patients with mild to moderate hypertension of yin deficiency and yang hyperactivity were randomly divided into a magnetotherapy group (33 cases, 3 cases dropped out) and a non-magnetotherapy group (33 cases, 4 cases dropped out). Both groups were given antihypertensive drugs based on their clinical conditions. The magnetotherapy group and the non-magnetotherapy group wore surface magnetic therapy bands with or without magnetic poles, respectively, at unilateral Neiguan (PC6) and Waiguan (TE5). Intervention was administered once daily, 8 h each time, for a continuous period of 4 weeks. Traditional Chinese Medicine (TCM) syndrome score, Du's hypertension quality of life (QOL) scale score, office blood pressure, and 24-hour ambulatory blood pressure were assessed before and after the intervention, and the clinical efficacy was evaluated after intervention. RESULTS: After the intervention, both groups showed reductions in TCM syndrome scores, office systolic blood pressure (SBP), and diastolic blood pressure (DBP) compared with those before intervention (P<0.001), and their Du's QOL scores increased (P<0.001). The magnetotherapy group had lower TCM syndrome score and office SBP and DBP than those in the non-magnetotherapy group (P<0.001), while Du's QOL score was higher (P<0.001). After the intervention, all 24-hour ambulatory blood pressure indexes in the magnetotherapy group were reduced compared with those before intervention (P<0.05); in the non-magnetotherapy group, 24-hour average diastolic blood pressure (24hDBP), nighttime average systolic blood pressure (nSBP), and nighttime average diastolic blood pressure (nDBP) were reduced (P<0.05). The 24-hour average systolic blood pressure (24hSBP), 24hDBP, daytime average systolic blood pressure (dSBP), daytime average diastolic blood pressure (dDBP), and nSBP after intervention in the magnetotherapy group were lower than those in the non-magnetotherapy group (P<0.05). The total effective rate in the magnetotherapy group was 93.3% (28/30), which was higher than 75.9% (22/29) in the non-magnetotherapy group (P<0.05). CONCLUSION Acupoint magnetotherapy as an adjunctive treatment for mild to moderate hypertension with yin deficiency and yang hyperactivity could effectively alleviate clinical symptoms and TCM syndromes, improve quality of life, and reduce blood pressure level.

The nucleus tractus solitarius (NTS) is the primary brain region for receiving and integrating cardiovascular afferent signals. It plays a crucial role in maintaining balance of autonomic nervous system and regulating blood pressure through cardiovascular reflexes. Neurons within the NTS form complex synaptic connections and interact reciprocally with other brain regions. The NTS regulates autonomic nervous system activity and arterial blood pressure through modulating baroreflex, sympathetic nerve activity, renin-angiotensin-aldosterone system, and oxidative stress. Dysfunctions in NTS activity may contribute to hypertension. Understanding the NTS' role in centrally regulating blood pressure and alterations of neurotransmission or signaling pathways in the NTS may provide rationale for new therapeutic strategies of prevention and treatment. This review summarizes the research findings on autonomic nervous system regulation and arterial blood pressure control by NTS, as well as unresolved questions, in order to provide reference for future investigation.

This study predicts the quality markers(Q-markers) for the cough-relieving and phlegm-expelling effects of Kening Granules based on pharmacodynamics, plasma drug chemistry, network pharmacology, and pharmacokinetics. Strong ammonia solution spray and phenol red secretion assays were employed to evaluate the cough-relieving and phlegm-expelling effects of Kening Granules. Twentysix absorbed prototype components of Kening Granules were identified by ultra high performance liquid chromatography coupled with QExactive Plus quadrupole/Orbitrap high resolution mass spectrometry(UHPLC-Q-Exactive Plus Orbitrap HRMS). Through network pharmacology, 11 potential active components were screened out for the cough-relieving and phlegm-expelling effects of Kening Granules. The 11 components acted on 40 common targets such as IL6, TLR4, and STAT3, which mainly participated in PI3K/Akt, HIF-1, and EGFR signaling pathways. Pharmacokinetic quantitative analysis was performed for 7 prototype components. Three compounds including azelaic acid, caffeic acid, and vanillin were identified as Q-markers for the cough-relieving and phlegm-expelling effects of Kening Granules based on their effectiveness, transmissibility, and measurability. The results of this study are of great significance for clarifying the pharmacological substance basis, optimizing the quality standards, and promoting the clinical application of Kening Granules.

A high performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS) method was established for simultaneous determination of seven characteristic components from the active fraction of Alpiniae Officinarum Rhizoma in rat plasma, including galangin, kaempferol, kaempferide, pinocembrin, 1,7-diphenyl-4-en-3-heptanone, 5-hydroxy-7-(4-hydroxy-3-methoxyphenyl)-1-phenyl-3-heptanone(DHPA), and 7-(4-hydroxy-3-methoxyphenyl)-1-phenyl-4-en-3-heptanone(DPHB). The new developed HPLC-MS/MS method was applied to study the pharmacokinetics of the 7 characteristic components in rats with Helicobacter pylori gastritis. A Waters Sunfire C_(18) column(2.1 mm×150 mm, 3.5 μm) was used. The acetonitrile-aqueous solution(containing 0.1% formic acid) was adopted as the mobile phase for gradient elution. Seven components and internal standard(chlorogenic acid) were separated within 12 min. Mass spectrometric detection was performed in multiple reaction monitoring(MRM) mode using electrospray ionization(ESI) source with fast switching between positive and negative ions. The method was verified by specificity, linearity, precision, accuracy, recovery, matrix effect, and stability and met the requirements of pharmacokinetic study on the 7 components in rat plasma. Pharmacokinetic results showed that the average peak time(T_(max)) of the 7 components was 0.31-2.19 h, their elimination half-life(t_(1/2)) was 5.26-16.65 h, and the average residence time(MRT) was 6.29-31.03 h after the oral administration of the active fraction of Alpiniae Officinarum Rhizoma to rats with H. pylori gastritis. The plasma exposure levels of galangin and DHPA were higher than those of the other components. The concentration-time curves of four detected flavonoids showed obvious double peaks. This study elucidated the pharmacokinetic characteristics of 7 characteristic components from the active fraction of Alpiniae Officinarum Rhizoma in rats with H. pylori gastritis, providing a scientific basis for the identification of the pharmacodynamic substances of Alpiniae Officinarum Rhizoma for treatment of H. pylori gastritis and the clinical application of Alpiniae Officinarum Rhizoma in the prevention and treatment of H. pylori gastritis.

Hypertension is a major risk factor for cardiovascular diseases. Controlling blood pressure can reduce the incidence of cardiovascular events and mortality. The patients with hypertension are mainly treated with antihypertensive drugs. For the patients who can't achieve the target blood pressure with a single drug, comprehensive treatment strategies become particularly important. Chinese patent medicines are prepared by modern extraction and processing technology based on the basic theory of traditional Chinese medicine(TCM). Due to the stable antihypertensive effect, target organ protection, and synergistic effect with western medicine, Chinese patent medicines are becoming one of the effective options for the treatment of hypertension. At present, there are many systematic reviews on the treatment of hypertension with Chinese patent medicines, which makes it difficult for health policy makers and health service providers to choose the best evidence for the treatment. Umbrella review can integrate multiple systematic reviews to comprehensively assess the quality of evidence and potential bias, thereby providing high-quality evidence-based medicine basis for formulating clinical guidelines and optimizing treatment strategies. In this study, the systematic reviews/Meta-analysis of Chinese patent medicines in the treatment of essential hypertension were systematically searched. Sixty-nine articles were included for the umbrella review. Literature information was extracted, and the corrected covered area(CCA) was calculated to quantitatively evaluate the overlap degree of original studies in systematic reviews/Meta-analysis. The risk of bias in systematic reviews(ROBIS) tool and Cochrane RoB tool 2.0 were used to assess the risk of bias of the included studies. A Measure Tool to Assess Systematic Reviews 2(AMSTAR 2) was used to evaluate the methodological quality of systematic reviews/Meta-analysis. The quality of evidence was evaluated based on the Grade of Recommendations Assessment, Development and Evaluation(GRADE). The results showed that the Chinese patent medicines in the categories of treating wind, resolving stasis, and reinforcing healthy Qi were effective in lowering blood pressure. The Chinese patent medicines for resolving stasis combined with conventional treatment can lower blood pressure and the levels of low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglyceride, and total cholesterol in the treatment of hypertension complicated with coronary heart disease and hypertension complicated with left ventricular hypertrophy. Moreover, the combined therapy can recover the interventricular septal thickness, left ventricular posterior wall thickness, left ventricular mass index, left ventricular end diastolic diameter, and left ventricular ejection fraction in the case of left ventricular hypertrophy. The Chinese patent medicines for resolving stasis and for replenishing Qi and restoring pulse can be used in combination with conventional treatment for hypertension complicated with arrhythmia, which can lower blood pressure while improving the outcome indicators such as the P-wave dispersion of arrhythmia, left atrial diameter, ejection fraction, heart rate, and recurrence time. Due to the heterogeneity, the efficacy evidence obtained by the umbrella review needs to be further verified through precise clinical studies and long-term follow-up.
