Objective: To observe the clinical efficacy and safety of Yiqi Tongluo Decoction in the intervention of early traditional Chinese medicine (TCM) syndromes after ischemic cerebrovascular disease (ICVD) intervention. Methods: From October 2020 to July 2023, a randomized, double-blind, placebo-controlled study was conducted to include 60 patients with qi deficiency, blood stasis, and phlegm obstruction syndrome after ICVD interventional therapy. They were assigned to the Yiqi Tongluo Decoction treatment group (30 cases) and the TCM placebo routine treatment control group (30 cases) according to the randomized block design. Both groups received routine standardized treatment of Western medicine, including dual antiplatelet, lipid regulation, and control of risk factors for cerebrovascular disease. The treatment group was treated with Yiqi Tongluo Decoction based on the control group. The course of treatment was 60 days and follow-up was carried out 2 and 6 months after the operation. The improvement of qi deficiency syndrome, blood stasis syndrome, phlegm syndrome score and TCM syndrome score, modified Rankin score (mRS), Barthel index (BI) score, Fatty acid-binding protein 4 (FABP4) level, incidence of transient ischemic attack (TIA) and ischemic stroke (IS) and incidence of adverse reactions, Head and neck CT angiography (CTA) or digital subtraction angiography (DSA) examination were collected. The clinical efficacy of the patients 2 months after the operation was taken as the main outcome index to preliminarily evaluate the early and long-term efficacy of Yiqi Tongluo Decoction after the ICVD intervention. The early and long-term clinical efficacy and safety of Western medicine standardized treatment combined with TCM Yiqi Tongluo Decoction on patients with qi deficiency, blood stasis and phlegm obstruction syndrome after ICVD intervention were evaluated. The safety of Yiqi Tongluo Decoction in the treatment of patients after ICVD intervention with white blood cell (WBC), C-reactive protein (CRP), fibrinogen (FIB), plasminogen time (PT), recurrence of cerebral ischaemia and restenosis in patients at 2 and 6 months after treatment were evaluated. Results: Compared to the control group, the TCM syndrome scores for qi deficiency, blood stasis and phlegm syndrome in the treatment group reduced significantly, the clinical efficacy improved significantly, the mRS score and FABP4 were reduced, and the BI score was increased. Adverse events such as cerebral ischaemia were fewer in the treatment group than in the control group, but the difference was not statistically significant; levels of CRP, WBC and PT were reduced, and levels of FIB were reduced at 6 months post-treatment, all P<0.01, and images were intuitively compared. The treatment group was superior to the control group. Conclusion Yiqi Tongluo Decoction combined with Western medicine standard treatment can improve the early clinical efficacy of ICVD patients with qi deficiency, blood stasis and phlegm obstruction syndrome after interventional surgery, improve neurological impairment and daily living ability, reduce the state of qi deficiency syndrome, blood stasis syndrome and phlegm syndrome after interventional surgery, and improve the clinical efficacy of TCM. At the same time, it can reduce the level of FABP4, the target of atherosclerosis and restenosis after interventional surgery, reduce the level of inflammation after interventional surgery in patients with ICVD, regulate coagulation function, and reduce the incidence of long-term recurrence of cerebral ischemia after interventional surgery, with good safety.

Medical accessibility reflects the actual ability of patients to use healthcare services, and is an important indicator for evaluating the quality of healthcare services from both the supply and demand perspectives. Inadequate medical accessibility is prevalent in dialysis patients and adversely affects clinical prognosis. In recent years, the number of peritoneal dialysis patients in China has increased remarkably, and the inequality of medical accessibility is particularly serious. However, the relationship between medical accessibility and clinical prognosis of peritoneal dialysis is still uncertain, and requires further study to provide evidence for formulating relevant health policies. This article reviews the concept and research indicators of medical accessibility, and the influence of medical accessibility on the clinical prognosis, to raise the awareness of medical accessibility inequality and help to improve care quality and survival rate in dialysis patients.

Objective To analyze the allocation efficiency of medical and health resources in 26 tertiary hospitals in Suzhou from 2017 to 2022 and perform quantitative analysis in order to provide suggestions for relevant departments to rationally coordinate the health resources allocation,regional health planning and hospital management.Methods The number of health technicians,the number of beds in health institutions and the total health expenditure were selected as input indicators,while the number of diagnostic and treatment visits and the number of discharged patients were selected as output indicators.The efficiency was measured by the SBM(Slack-Based Measure)model and the SBM window model respectively.Results Influenced by public health emergencies,the allocation efficiency of medical resources in tertiary hospitals in Suzhou city decreased first and then started to increase Under the two models,the average efficiency scores of 26 hospitals were 0.687 and 0.707,respectively.Notably,under the SBM window model,19 hospitals(73％)achieved efficiency scores near or above the average.Conclusion The two models present a conclusion that the overall efficiency of the tertiary hospitals in Suzhou is generally effective.To further enhance the allo-cation and utilization of medical resources,it is suggested that a comprehensive consideration of health needs guide the planning of medical resource distribution.Leveraging information technology to innovate medical service models,and strengthening internal de-velopment and management practices are essential strategies for promoting high-quality development in tertiary hospitals.

To analyze a case of severe avian influenza A (H5N6) virus infection resulting in severe pneumonia and acute respiratory distress syndrome (ARDS) was admitted to Guilin Municipal Hospital of Traditional Chinese Medicine on July 6, 2023. The clinical data and treatment of this patient were analyzed retrospectively. The initial clinical manifestations of the patient were fever, cough, and expectoration, and the antigen test for influenza A virus was positive. Chest CT showed: double lung texture increased and thickened, and multiple patchy high-density shadows with air-containing bronchial shadows were found in the left lung, especially in the left upper lobe; a few patchy increased-density shadows were also seen in the lower lobe of the right lung, along with left-sided pleural effusion. Metagenomic next-generation metagenomic sequencing (mNGS) of bronchoalveolar lavage fluid was performed to identify the pathogen as influenza A virus H5N6. On the 4th day of admission, the patient's condition rapidly progressed to ARDS, which could not be improved by high-flow oxygen therapy, mechanical ventilation, and prone position ventilation. Subsequently, with the assistance of veno-venous extracorporeal membrane oxygenation (VV-ECMO), the patient's lung function gradually improved. Extracorporeal membrane oxygenation（ECMO） was withdrawn after 25 days, and the patient recovered and was discharged after a hospital stay of 41 days. Patients with severe avian influenza A (H5N6) usually have critical illness and rapid progression, often rapidly progressing to ARDS. When conventional mechanical ventilation cannot correct hypoxemia, VV-ECMO auxiliary treatment should be administered as early as possible. In addition, mNGS can help to quickly identify the diagnosis and differential diagnosis of avian influenza A (H5N6) in the early stage of the disease, particularly suitable for the diagnosis of severe and emergency infections.

Traumatic cerebrospinal fluid leakage commonly presents in traumatic brain injury patients, and it may lead to complications such as meningitis, ventriculitis, brain abscess, subdural hematoma or tension pneumocephalus. When misdiagnosed or inappropriately treated, traumatic cerebrospinal fluid leakage may result in severe complications and may be life-threatening. Some traumatic cerebrospinal fluid leakage has concealed manifestations and is prone to misdiagnosis. Due to different sites and mechanisms of trauma and degree of cerebrospinal fluid leak, treatments for traumatic cerebrospinal fluid leakage varies greatly. Hence, the Craniocerebral Trauma Professional Group of Neurosurgery Branch of Chinese Medical Association and the Neurological Injury Professional Group of Trauma Branch of Chinese Medical Association organized relevant experts to formulate the " Chinese expert consensus on the diagnosis and treatment of traumatic cerebrospinal fluid leakage in adults ( version 2023)" based on existing clinical evidence and experience. The consensus consisted of 16 recommendations, covering the leakage diagnosis, localization, treatments, and intracranial infection prevention, so as to standardize the diagnosis and treatment of traumatic cerebrospinal fluid leakage and improve the overall prognosis of the patients.

Objective:To explore the association between short-term exposures to fine particulate matter (PM 2.5) on blood lipids in the elderly. Methods:In this panel study, five repeated measurements were performed on 76 people aged 60-69 in Jinan city. Each participant had a PM 2.5 monitor for 72 hours before each health examination, including a questionnaire survey, physical examination, and biological sample collection. Serum triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were examined, and non-HDL-C concentrations were calculated by subtracting HDL-C from TC. The generalized linear mixed-effects model was used to quantify the association of personal PM 2.5 exposure at different lag with blood lipids and dyslipidemia. Results:The age of 70 participants was (65.0±2.8) years, of which 48.6% (34/70) were males. The BMI of participants was (25.0±2.5) kg/m 2. Their TC, TG, LDL-C, HDL-C, and non-HDL-C concentrations were (5.75±1.32), (1.55±0.53), (3.27±0.94), (1.78±0.52), and (3.97±1.06) mmol/L, respectively. Generalized linear mixed-effects model showed that after adjusting for confounding factors, at lag 72 hours, each 10 μg/m 3 increase in PM 2.5 was associated with the percentage change in TC, LDL-C, HDL-C and non-HDL-C about 1.77% (95% CI: 1.22%-2.32%), 1.90% (95% CI: 1.18%-2.63%), 1.99% (95% CI: 1.37%-2.60%) and 1.74% (95% CI: 1.11%-2.37%), and the OR values (95% CI) of hypercholesterolemia, hypertriglyceridemia and hyperbetalipoproteinemia were 1.11 (1.01-1.22), 1.33 (1.03-1.71) and 1.15 (1.01-1.31), respectively. Conclusion:There is a significant association of short-term PM 2.5 exposure with the concentration of blood lipids and the risk of dyslipidemia in the elderly.

Here, we investigated the role of a polycomb protein BMI-1 in CRCLM. Immunohistochemical analysis showed that BMI-1 expression in liver metastases was upregulated and associated with T4 stage, invasion depth and right-sided primary tumor. Knockdown

Objective:To investigate the effect of treadmill training on spasticity and the expression of potassium chloride co-transporter 2 (KCC2) after blocking BDNF-TrkB signaling pathway in rats with incomplete spinal cord injury (SCI).Methods:Forty female Sprague-Dawley rats were randomly divided into a sham-operation group (Sham group), an SCI+ phosphate-buffered saline group (SCI/PBS group), an SCI-treadmill training+ PBS group (SCI-TT/PBS group), an SCI/TrkB-IgG group and an SCI-TT/TrkB-IgG group. All of the rats underwent 1 week of intrathecal catheterization, and then T 10 incomplete SCI was induced. In the Sham group the spinal cord was only exposed. Seven days later, BDNF-TrkB signaling was blocked in the SCI/TrkB-IgG and SCI-TT/TrkB-IgG groups using the TrkB-IgG. The remaining three groups were controls treated with PBS. The SCI-TT/PBS and SCI-TT/TrkB-IgG groups began exercising 7 days after the SCI and continued for 4 weeks. The spasticity in their hind limbs was assessed using the Asworth assessment and H reflex (H-max/M-max ratio). The expression of KCC2 in the distal spinal cord was detected using western blotting and immunohistochemistry. Results:After the SCI the average Ashworth spasticity grades of the four SCI groups increased significantly compared with the Sham group. The average Ashworth spasticity grade of the SCI-TT/PBS group was significantly lower than those of the SCI/PBS and SCI/TrkB-IgG groups in the 3rd through the 5th week, and the SCI-TT/PBS group′s average grade was significantly less than that of the SCI-TT/TrkB-IgG group after 4 weeks. Within 5 weeks the average H-max/M-max ratio of the Sham group remained unchanged, significantly lower than the other 4 groups′ averages. There was no significant difference in the H-max/M-max ratio among the 4 groups of injured rats within 2 weeks after the SCI, but after 3-5 weeks the average H-max/M-max ratio of the SCI-TT/PBS group was significantly lower than those of the SCI/PBS, SCI/TrkB-IgG and SCI-TT/TrkB-IgG groups. At the 4th and 5th week the average H-max/M-max ratio in the SCI-TT/TrkB-IgG group was significantly lower than that in the SCITrkB-IgG group. And after 5 weeks the average expression of KCC2 in the anterior horn of the injured spinal cord was significantly lower in the 4 SCI groups than in the Sham group. Exercise significantly increased the expression of KCC2 in the SCI-TT/PBS group, and its immune intensity and relative optical density were significantly higher than those in the SCI/PBS, SCI/TrkB-IgG and SCI-TT/TrkB-IgG groups. However, there was no significant difference between the SCI/TrkB-IgG group and the SCI-TT/TrkB-IgG group.Conclusions:Treadmill training can improve spasticity after incomplete SCI and the expression of KCC2 in the distal spinal cord, at least in rats.

Objective:To study the differential expression and significance of auricular cartilage protein phosphorylation profile in different degrees of development on the normal and the abnormal side of patients with congenital non-syndromic microtia.Methods:Collected 4 cases of unilateral congenital non-syndromic patients from March 2017 to March 2019 in Chinese Academy of Medical Sciences Plastic Surgery Hospital, including 4 pairs of matched normal auricle cartilage and residual auricle cartilage (2 males and 2 females, aged 6 years). Signal phosphorylation broad-spectrum screening antibody chip (PEX100) was used to screen the protein phosphorylation profiles of the cartilage on the normal and abnormal cartilages. The residual ear cartilage group was used as the experimental group, and the normal ear cartilage was used as the control group. The ratio of phosphorylation of the cartilage in the residual ear of patients was compared with that of the control group. Residual ear cartilage protein phosphorylation / normal ear cartilage protein phosphorylation ratio ≥2.0 indicates an up-regulated protein, and ≤0.5 indicates a down-regulated protein. The differential proteins obtained from the experiments were analyzed using String database and KEGG(Kyoto Encyclopedia of Genes and Genomes) PATHWAY databases.Results:The experimental/control group (residual ear cartilage/ normal ear cartilage) had a protein phosphorylation ratio of FC ≥ 2 and ≤ 0.5 with 110 proteins. Among them, 102 were up-regulation and 8 were down-regulation. The KEGG database was used to perform signal pathway enrichment analysis of proteins showing differences in phosphorylation levels. The screened differential proteins were enriched in 20 signaling pathways including PI3K-AKT, Focal adhension singaling pathway except the classic signaling pathways and the list of differentially phosphorylated proteins was imported into the STRING database to map the protein interactions network.Conclusions:There is a significant difference in the phosphorylation of proteins between normal auricle cartilage and residual auricle cartilage. Differentially phosphorylated proteins are enriched in signal pathways such as PI3K-AKT and focal adhesion, which suggests that the cause of the difference in development of bilateral ear cartilage may be related to ear cartilage proliferation, adhesion, migration and other activities during the embryonic period.
