Analysis of prescription status of antihypertensive drugs in Chinese patients with hypertension based on real-world study
AbstractBackground Globally, the prevalence of hypertension and the accompanying burden of cardiovascular disease are increasing. Through drug utilization research, we can understand the prescription status of hypertension patients and promote rational drug use. The purpose of this retrospective study was to describe the current prescription pattern of antihypertensive drugs in Chinese patients and determine the compliance level of treatment guidelines.Materials and methods Around 11.1 million patients who received a prescription for antihypertensive therapy between January 2021 to December 2021 were obtained from a database of Hangzhou Kang Sheng Health Consulting CO., Ltd.Results The mean age of hypertensive patients was 54.75 ± 12.98 years. About 6.7 million (60.30%) were males. About 46.07% of patients had comorbidities. The most common classes of antihypertensive medications used were calcium channel blockers (CCBs) and angiotensin II receptor blockers (ARBs). Around 78.33% of participants were on monotherapy. Diuretics + ARBs and Diuretics + CCBs + ARBs were the most commonly prescribed pattern in two-drug combination therapy and three-drug combination therapy, respectively.Conclusions CCBs and ARBs were the two most frequently prescribed for patients with hypertension. The prescription pattern of antihypertensive medications in the study largely complied with recommended Chinese hypertension guidelines.Key messagesCardiovascular disease is the most common complication of hypertension.Calcium channel blockers (CCBs) and angiotensin II receptor blockers (ARBs) are the two most commonly used drugs for hypertension patients in China.The proportion of combination prescription pattern in Chinese hypertensive patients is low
Current prescription status of antihypertensive drugs in Chinese patients with hypertension: analysis by type of comorbidities
In 2020, the National Center for Cardiovascular Diseases with National Committee on Hypertension Management in Primary Health Care in China issued revised national clinical practice guidelines on the management of hypertension in primary health care based on the 2018 Chinese guidelines for the management of hypertension. To evaluate adherence to the guidelines, this retrospective study assessed the real-world status of antihypertensive drug prescribing for Chinese patients with hypertension, classified by comorbidity: coronary heart disease, diabetes mellitus, heart failure, stroke, and renal disease. About 1088212 hypertensive patients who received their first prescription for antihypertensive therapy between January 2021 to June 2021, were obtained from a database of Hangzhou Kang Sheng Health Consulting CO., Ltd. Calcium channel blockers (CCBs) and angiotensin II receptor blockers (ARBs) were the most common drugs prescribed for each comorbidity subgroup. Whereas diabetes mellitus or renal disease is a compelling indication for use of renin–angiotensin system inhibitors, CCBs were often administered in these subgroups. The treatment pattern for patients with coronary heart disease was closely similar to that for the overall patient population. Beta-blockers (BBs) were prescribed more frequently for patients with heart failure than for those with other comorbidities. Although antihypertensive drug prescription varied by comorbidity, pharmacological decisions were largely made under Chinese recommendations while physicians could select antihypertensive drugs based on the patients’ comorbidities. However, educational initiatives are still necessary to inspire clinicians to better familiarize themselves with the guidelines and manage hypertension comorbid diseases
Effectiveness of Digital Cognitive Behavior Therapy for the Treatment of Insomnia: Spillover Effects of dCBT
The effects of digital Cognitive Behavior Therapy for insomnia (dCBT-i) on sleep quality have been previously demonstrated but the spillover effects on fatigue, flow (a state of immersion in activities of interest), and cognitive flexibility remain unclear. The current study examined the effectiveness of dCBT-i. A total of 97 college students (20.96 ± 1.87 years, 73.1% female students) were randomly selected from a shortlist and divided into sleep intervention (n = 39), conventional education (n = 37), and healthy control (n = 21) groups. Task switching paradigm, Fatigue Severity Scale (FSS), Flow Experience Scale (FES), and the Chinese version of the Pittsburgh Sleep Quality Index (CPSQI) were measured pre- and post-intervention. Results show that the sleep quality of the intervention group improved, and fatigue was relieved. Participants in the sleep intervention group had increased flow experience scores post-intervention and improved cognitive flexibility. The control group’s sleep quality deteriorated and fatigue level increased. dCBT-i can not only achieve a significant improvement in sleep quality and reduce fatigue, but also improve learning abilities, quality of life, flow, and cognitive flexibility. Future research should pay attention to indicators such as work efficiency, sedative use, and the durability and stability of such effects
Sleep duration trajectories and all-cause mortality among Chinese elderly: A community-based cohort study
Abstract Background China is among the largest and fastest aging countries. The elderly population is more vulnerable, with higher proportion of inappropriate sleep duration and risk of mortality, compared with young and middle-aged adults. Single-measured sleep duration has been associated with mortality, but the health effects of long-term sleep duration trajectories remain unknown. This study aimed to explore the prospective associations between sleep duration trajectories and all-cause mortality among Chinese elderly. Methods Participants (n = 3,895; median age: 82 years; females: 53.3%) who reported sleep duration in all three surveys (2005, 2008, and 2011) from the community-based Chinese Longitudinal Healthy Longevity Survey (CLHLS) were followed up until 2019 (about 8 years). We identified sleep duration trajectories by latent class mixed model and explored their association with all-cause mortality using Cox hazard proportional regression and Laplace regression models. Further, stratified analysis by demographic characteristics and lifestyles and sensitivity analysis by lag effect, health-related factors, and inverse probability weighting were used to verify the robustness of the association. In addition, we explored the threshold effect of baseline sleep duration on the risk of all-cause mortality. Results We documented 1,881 all-cause deaths during 16,689 person-years of follow-up. Five sleep duration trajectories were identified: moderately increased trajectory (28.1%), rapidly increased trajectory (7.2%), persistent sleep trajectory of 7 h (33.7%), moderately decreased trajectory (21.3%), and rapidly decreased trajectory (9.7%). Compared with the persistent sleep trajectory of 7 h, the multivariable-adjusted HRs (95%CI) for moderately increased trajectory, rapidly increased trajectory, moderately decreased trajectory, and rapidly decreased trajectory were 1.21 (1.08, 1.36), 1.21 (1.01, 1.44), 0.95 (0.82, 1.10), and 0.93 (0.78, 1.11), respectively; and the corresponding difference in median survival time (95%CI) were -0.53 (-1.01, -0.05), -0.43 (0.16, -1.02), 0.26 (-0.34, 0.86), and 0.25 (-0.51, 1.02), respectively. Stratified and sensitivity analyses showed consistent results. Threshold analysis indicated a sharply increased risk of mortality in participants whose sleep exceeds 9 h (HR = 1.20, 95%CI: 1.11, 1.30). Conclusion Compared with the persistent sleep trajectory of 7 h, moderately and rapidly increased sleep duration trajectories were associated with higher subsequent mortality in Chinese elderly. Those who report sleep exceeding 9 h may be at high risk for all-cause mortality
The Effect of Complementary and Alternative Medicine on Subfertile Women with In Vitro Fertilization
About 10–15% of couples have difficulty conceiving at some point in their reproductive lives and thus have to seek specialist fertility care. One of the most commonly used treatment options is in vitro fertilization (IVF) and its related expansions. Despite many recent technological advances, the average IVF live birth rate per single initiated cycle is still only 30%. Consequently, there is a need to find new therapies to promote the efficiency of the procedure. Many patients have turned to complementary and alternative medical (CAM) treatments as an adjuvant therapy to improve their chances of success when they undergo IVF treatment. At present, several CAM methods have been used in infertile couples with IVF, which has achieved obvious effects. However, biologically plausible mechanisms of the action of CAM for IVF have not been systematically reviewed. This review briefly summarizes the current progress of the impact of CAM on the outcomes of IVF and introduces the mechanisms

Transient {beta}2-adrenoceptor activation confers pregnancy loss by disrupting embryo spacing at implantation.
Pregnancy loss is a serious social and medical issue, with one important cause associated with aberrant embryo implantation during early pregnancy. However, whether and how the process of embryo implantation is affected by environmental factors such as stress-induced sympathetic activation remained elusive. Here we report an unexpected, transient effect of β(2)-adrenoreceptor (β(2)-AR) activation (day 4 postcoitus) in disrupting embryo spacing at implantation, leading to substantially increased midterm pregnancy loss. The abnormal embryo spacing could be prevented by pretreatment of β(2)-AR antagonist or genetic ablation of β-AR. Similar β(2)-AR activation at day 5 postcoitus, when implantation sites have been established, did not affect embryo spacing or pregnancy outcome, indicating that the adverse effect of β(2)-AR activation is limited to the preimplantation period before embryo attachment. In vitro and in vivo studies demonstrated that the transient β(2)-AR activation abolished normal preimplantation uterine contractility without adversely affecting blastocyst quality. The contractility inhibition is mediated by activation of the cAMP-PKA pathway and accompanied by specific down-regulation of lpa3, a gene previously found to be critical for uterine contraction and embryo spacing. These results indicated that normal uterine contraction-mediated correct intrauterine embryo distribution is crucial for successful ongoing pregnancy. Abnormal β(2)-AR activation at early pregnancy provided a molecular clue in explaining how maternal stress at early stages could adversely affect the pregnancy outcome

Aquaporin3 is a sperm water channel essential for postcopulatory sperm osmoadaptation and migration.
In the journey from the male to female reproductive tract, mammalian sperm experience a natural osmotic decrease (e.g., in mouse, from ~415 mOsm in the cauda epididymis to ~310 mOsm in the uterine cavity). Sperm have evolved to utilize this hypotonic exposure for motility activation, meanwhile efficiently silence the negative impact of hypotonic cell swelling. Previous physiological and pharmacological studies have shown that ion channel-controlled water influx/efflux is actively involved in the process of sperm volume regulation; however, no specific sperm proteins have been found responsible for this rapid osmoadaptation. Here, we report that aquaporin3 (AQP3) is a sperm water channel in mice and humans. Aqp3-deficient sperm show normal motility activation in response to hypotonicity but display increased vulnerability to hypotonic cell swelling, characterized by increased tail bending after entering uterus. The sperm defect is a result of impaired sperm volume regulation and progressive cell swelling in response to physiological hypotonic stress during male-female reproductive tract transition. Time-lapse imaging revealed that the cell volume expansion begins at cytoplasmic droplet, forcing the tail to angulate and form a hairpin-like structure due to mechanical membrane stretch. The tail deformation hampered sperm migration into oviduct, resulting in impaired fertilization and reduced male fertility. These data suggest AQP3 as an essential membrane pathway for sperm regulatory volume decrease (RVD) that balances the "trade-off" between sperm motility and cell swelling upon physiological hypotonicity, thereby optimizing postcopulatory sperm behavior
Acupuncture and Clomiphene Citrate for Live Birth in Polycystic Ovary Syndrome: Study Design of a Randomized Controlled Trial
Acupuncture is an alternative therapy to induce ovulation in women with polycystic ovary syndrome (PCOS), but there is no study reporting the live birth rate following ovulation induction by acupuncture or its potential as an adjuvant treatment to clomiphene citrate (CC). We assess the efficacy of acupuncture with or without CC in achieving live births among 1000 PCOS women in Mainland China. This paper reports the methodology of an ongoing multicenter randomized controlled trial. The randomization scheme is coordinated through the central mechanism and stratified by the participating sites. Participants will be randomized into one of the four treatment arms: (A) true acupuncture and CC, (B) control acupuncture and CC, (C) true acupuncture and placebo CC, and (D) control acupuncture and placebo CC. To ensure the quality and integrity of the trial we have developed a unique multinational team of investigators and Data and Safety Monitoring Board. Up to the end of April 2013, 326 subjects were recruited. In conclusion, the success of this trial will allow us to evaluate the additional benefit of acupuncture beyond the first line medicine for fertility treatment in PCOS women in an unbiased manner
