Objective:To review the literature on improving patients′medical experience, analyze the current research status in this field, and provide references for enhancing patients′medical experience.Methods:A search was conducted for studies related to improving patients′medical experience published from January 2015 to November 2024 in eight databases, including CNKI and Web of Science. Using software CiteSpace 6.4.R1 and VOSviewer 1.6.19 to analyze publication trends, keyword clustering, existing problems in the process of improving patients′medical experience, and the measures taken.Results:6 507 articles were included, of which 4 452 were in English (68.4%) and 2 055 were in Chinese (31.6%). The annual number of publications showed a nearly linear growth trend ( R2 = 0.983 9). The clustering analysis results indicated that domestic and international research mainly focused on patient-centered diagnostic and treatment systems, behaviors, services, and environments. Existing studies revealed that there were still problems such as long waiting times for appointments and consultations (292 articles), uneven distribution of medical resources (198 articles), and poor doctor-patient communication (155 articles). To improve patients′medical experience, the following intervention measures were proposed: accelerating the medical reform process and strengthening government responsibilities (169 articles); enhancing service concepts and innovating service models (363 articles); optimizing the consultation process and simplifying medical procedures (221 articles); improving the consultation environment and optimizing the facilities in the consultation area (181 articles); and integrating technological advantages to cover the entire medical process (346 articles). Conclusions:Research on improving patients' medical experience was increasingly attracting the attention of more and more scholars. Issues such as low service efficiency, unbalanced resource allocation, and poor doctor-patient communication need to be given special attention. In the future, it is recommended to enhance the experience of patients′ medical experience by strengthening policy and institutional guarantees, accelerating the construction of information technology, improving doctor-patient communication skills and humanistic care, and enhancing the capacity of primary medical services.

BACKGROUND: Previous evidence showed that ambient air pollution and cardiovascular mortality are related. However, there is a lack of evidence towards the modification effect of long-term lifestyle on the association between short-term ambient air pollution and death from cardiovascular events. METHOD: A total of 14,609 death from major adverse cardiovascular events (MACE) were identified among the China Kadoorie Biobank participants from 2013 to 2018. Ambient air pollution exposure including particulate matter 2.5 (PM_2.5), SO₂, NO₂, CO, and O₃ from the same period were obtained from space-time model reconstructions based on remote sensing data. Case-crossover design and conditional logistic regression was applied to estimate the effect of short-term exposure to air pollutants on MACE mortality. RESULTS: We found MACE mortality was significantly associated with PM_2.5 (relative percent increase 2.91% per 10 µg/m³ increase, 95% CI 1.32-4.53), NO₂ (5.37% per 10 µg/m³ increase, 95% CI 1.56-9.33), SO₂ (6.82% per 10 µg/m³ increase, 95% CI 2.99-10.80), and CO (2.24% per 0.1 mg/m³ increase, 95% CI 1.02-3.48). Stratified analyses indicated that drinking was associated with elevated risk of MACE mortality with NO₂ and SO₂ exposure; physical inactivity was associated with higher risk of death from MACE when exposed to PM_2.5; and people who had balanced diet had lower risk of MACE mortality when exposed to CO and NO₂. CONCLUSIONS The study results showed that short-term exposure to ambient PM_2.5, NO₂, SO₂, and CO would aggravate the risk of cardiovascular mortality, yet healthy lifestyle conduct might mitigate such negative impact to some extent.

BACKGROUND:Unicompartmental knee arthroplasty has been paid more and more attention because of its advantages of fewer traumas,less blood loss,less complications,faster recovery,excellent knee function and high prosthetic survival rate.Most of the relevant reports focused on its clinical effect,but the changes in the levels of relevant inflammatory cytokines in patients after unicompartmental knee arthroplasty were rarely reported. OBJECTIVE:To investigate the effect of unicompartmental knee arthroplasty in patients with medial compartment osteoarthritis of the knee and the changes of interleukin-1,interleukin-6,and tumor necrosis factor-α levels. METHODS:A total of 30 patients with medial compartment osteoarthritis of the knee who received unicompartmental knee arthroplasty from September 2021 to March 2023 and met the inclusion criteria were selected as the study subjects.Medial angle of proximal tibia,femoral and tibial angle,pain visual analog scale score,hospital for special surgery score,knee joint range of motion,synovial fluid interleukin-1,interleukin-6,and tumor necrosis factor-α levels before and after surgery were compared and statistically analyzed. RESULTS AND CONCLUSION:(1)All 30 patients had grade I wound healing.All patients were followed up for more than 6 months after surgery.There were no complications such as prosthesis loosening and dislocation of prosthesis liner in all patients.(2)The medial proximal tibia angle and the femoral and tibial angles measured after operation were significantly improved(P<0.05).(3)The visual analog scale score,hospital for special surgery score and range of motion measured at 1,3,and 6 months after operation were better than those before operation(P<0.05),and showed a gradual improvement(P<0.05).(4)The levels of interleukin-1,interleukin-6,and tumor necrosis factor-α in synovial fluid at 3 and 6 months after operation were decreased gradually compared with those before operation(P<0.05)and showed a gradual downward trend at each time point after operation.(5)It is indicated that unicompartmental knee arthroplasty can effectively treat medial compartment osteoarthritis of the knee,significantly relieve pain,restore knee joint function,improve knee varus deformity and lower limb strength line,and reduce the levels of inflammatory cytokines interleukin-1,interleukin-6,and tumor necrosis factor-α in joints to a certain extent.

Disorders of the gut flora (GF) affect the level of 5-hydroxytryptamine (5-HT) in the brain of patients with generalized anxiety disorder (GAD) and influence the development of the disease. Most of the acupuncture points selected for GAD are based on the principles of local acupuncture points and acupuncture points following the distant channels of the meridians, regarding Baihui (DU 20), Fengchi (GB 20), and Yintang (GV 29) as the main acupuncture points, and the acupuncture points selected for the regulation of GF are Zhongwan (CV 12), Tianshu (ST 25), and Guanyuan (RN 4) and Zusanli (ST 36). Recently, many studies have been conducted on the mechanism of action of acupuncture in the treatment of GAD from the perspective of GF, but few have investigated the theoretical of acupuncture points used to prevent and treat GAD. This paper discusses the theoretical basis of acupuncture to regulate the "microbiota-gut-brain axis" (MGBA) for the prevention and treatment of GAD, and proposes the method of "regulating the internal organs and calming the mind and relieving anxiety" through analyzing the researches on the regulation of GF and GAD.

Parkinson′s disease (PD) is the second most common neurodegenerative disease in middle-aged and elderly people. In addition to motor symptoms, PD also has many non motor symptoms, such as dysosmia, constipation, cognitive impairment, etc. Among them, dysosmia is a common non motor symptom of early Parkinson′s disease. Research has confirmed that olfactory dysfunction (OD) can appear before the typical clinical symptoms of PD, which is of great significance to the diagnosis and treatment of diseases. However, at present, the pathogenesis of OD is still unclear, and the inspection methods have not been unified, and there is no complete cure. This article reviews the latest research progress of dysosmia in Parkinson′s disease.

Essential tremor (ET) is a common dyskinesia disease characterized by tremor. ET is clinically heterogeneous. In addition to the motor symptoms with tremor as the main manifestation, it also includes non-motor symptoms such as neuropsychiatric symptoms (anxiety, depression), personality changes, sleep disorders, etc. Among them, anxiety and depression are the most common, and gradually worsen as the disease progresses, causing adverse effects on the quality of life of patients. Therefore, the early clinical full text of looking for ET psychiatric symptoms seems to have no content of the evaluation scale and is irrelevant. It is suggested that removing biomarkers plays an important role in the diagnosis and treatment of ET patients. Genome-Wide Association Studies (GWAS) describes the SLC1A2 gene associated with ET, and the EAAT2 or GLT1 encoded by this gene is associated with the anxiety and depression phenotypes of ET patients in non-motor symptoms. Up to now, the pathogenesis of ET patients is not clear, but many reports confirm that genetic factors play an important role in the pathogenesis of ET. Among them, SLC1A2 is expected to become a biomarker of the neuropsychiatric phenotype of the disease, providing a basis for clinical workers to take corresponding intervention measures in time. This article reviews SLC1A2 gene and essential tremor.

Objective To investigate the effects and mechanism of verbascoside on hypoxia-induced memory impairment.Methods The eight-arm maze was used to train mice′s spatial memory ability.After successful training, mice were randomly divided into five groups:a normoxic control group (distilled water, 0.1ml/10g), hypoxic model group (distilled water, 0.1ml/10g), the verbascoside low dose group (50 mg/kg), medium dose group (150 mg/kg), and high dose group (300mg/kg) were administered orally once a day for a total of 7days.After administration on the fourth day, except for the normoxic control group was placed in the animal room (1 500m), the remaining four groups were placed in a large-scale hypobaric chamber to simulate the hypoxic environment of the plateau (7 500m, 3days).Eight-armed maze test (4 000m) was used and the plasma and brain tissues were dissected out and measured for reactive oxygen species (ROS) in the brain, malondialdehyde (MDA), reduced glutathione (GSH) and total superoxide dismutase (T-SOD) activity in plasma and brain.Results Compared with the normoxic control group, the indexes of the eight-armed maze, ROS and MDA in the brain, MDA in the plasma of the hypoxia model group were significantly increased, and the GSH and T-SOD enzyme activities in the brain and plasma were notably decreased.Compared with the hypoxic model group, the indexes of the eight-armed maze, ROS and MDA in the brain, MDA in the plasma in the various groups of verbascoside were reduced more or less, the GSH and T-SOD enzyme activities in the brain and plasma slightly were increased.Conclusion Verbascoside could ameliorate the hypoxic memory impairment at high altitude, which might be related to the stabilization of the body′s antioxidant enzyme system balance and
