Objective:To investigate the correlation between serum albumin, urea nitrogen and Fazekas scores and cognitive function scores in patients with mild and medium ischemic stroke.Methods:Clinical data of 160 patients with acute ischemic stroke with the National Institutes of Health Stroke Scale (NIHSS)≤7 scores admitted to the Department of Neurology of the First Affiliated Hospital of Hainan Medical College from June 2021 to April 2023 were selected for a cross-sectional study. According to the Montreal Cognitive Assessment (MoCA) score, they were divided into normal cognitive group (28 cases) (MoCA≥26 scores), mild to moderate cognitive impairment group (74 cases) (MoCA 15-<26 scores), and severe cognitive impairment group (58 cases) (MoCA<15 scores). Demographic characteristics, serological indicators and imaging data of patients were collected, and the correlation between serum albumin, urea nitrogen and Fazekas scores and the total score of MoCA and the scores of each cognitive domain was analyzed. One-way ANOVA was used for comparison between the normal distribution and homogeneous variance data sets, LSD analysis was used for pairwise comparison, Kruskal-Wallis H test was used between the skew distribution or heterogeneous variance data sets. Bonferroni correction analysis was used for pairwise comparison. Chi-square test or Fisher exact probability method was used after the comparison between the count data sets. Spearman Spearman correlation analysis was performed on serum albumin, urea nitrogen and Fazekas scores with MoCA scores and cognitive domain scores. Multivariate ordered Logistic regression was used to analyze the independent risk factors of cognitive function in acute stage of mild and medium ischemic stroke patients. Results:The incidence of cognitive impairment in patients with acute mild and medium ischemic stroke was 82.50% (132/160). Comparison of age ((56.71±7.35), (60.32±10.20), (66.40±11.88) years old), sex (male/female: (23/5, 58/16, 33/25)), the proportion of education level above high school (25.0%(7/28), 16.2%(12/74), 6.9%(4/58)), hemoglobin ((149.26±14.91), (144.85±16.85), (137.63±17.22) g/L), albumin (39.5 (37.0, 41.2), 38.6(35.6, 40.8), 37.4 (34.5, 39.8) g/L), urea nitrogen (5.30 (4.00, 6.60), 4.81 (4.00, 6.32), 5.86 (4.55, 6.97) mmol/L), Hamilton Anxiety Scale (HAMA) score (5.0 (2.0, 10.0), 7.5 (5.0, 11.0), 10.0 (6.0, 14.3) scores),Hamilton Depression Scale (HAMA) score (5.5 (3.0, 12.5), 7.0 (4.0, 11.0), 9.5 (5.0, 14.0) scores), and Fazekas score (2.00 (1.25, 3.00), 2.00 (1.00, 4.00), 3.00 (2.00, 5.00) scores) among cognitive normal group, mild to moderate cognitive impairment group, and severe cognitive impairment group of patients, the difference were statistically significant (the statistical values were F=9.68, χ 2=9.29, χ 2=30.77, F=5.31, H=7.06, H=6.71, H=12.37, H=8.91, and H=10.96, respectively;the P values were <0.001, 0.010, <0.001, 0.006, 0.029, 0.035, 0.002, 0.012, and 0.004, respectively ). The total score of MoCA was negatively correlated with Fazekas score and serum urea nitrogen, but positively correlated with serum albumin ( r s values were -0.250, -0.168, and 0.212, respectively; P values were 0.001, 0.036, and 0.009, respectively). Serum albumin was positively correlated with scores in visual space and execution, naming, attention and orientation, serum urea nitrogen was negatively correlated with scores in language and orientation, and Fazekas score was negatively correlated with scores in visual space and execution, orientation, attention and language ( r s values were 0.291, 0.196, 0.191, 0.209, -0.205, -0.180, -0.248, -0.193, -0.188, and -0.183, respectively; P values were <0.001, 0.017, 0.020, 0.011, 0.012, 0.027, 0.002, 0.016, 0.020, and 0.023, respectively). Multiple Logistic regression analysis showed that low albumin ( OR=0.884, 95% CI: 0.813-0.963, P=0.005) and high urea nitrogen ( OR=1.195, 95% CI: 1.003-1.425, P=0.047) and high Fazekas scores ( OR=1.401, 95% CI: 1.132-1.733, P=0.002) were independent risk factors for cognitive function, while high education level was a protective factor ( OR=0.062, 95% CI: 0.019-0.202, P<0.001). Conclusion:The incidence of acute cognitive impairment is high in patients with mild and medium ischemic stroke. Higher education level is a protective factor for cognitive function. Low albumin, high urea nitrogen and high Fazekas score are independent risk factors for cognitive function.

OBJECTIVE: To investigate the role of platelet-rich plasma (PRP) in inducing the M2 macrophage polarization via regulating AMPK singling pathway. METHODS: The expressions of M1 marker CD11c and M2 marker CD206 in macrophages of blank control group, LPS group, LPS+PRP group, and LPS+PRP+Compound C group were detected by flow cytometry. Western blot was used to observe the effects of PRP on the expression of AMPK-mTOR signaling pathway-related proteins at different times (12 h, 18 h and 24 h) after LPS treatment. RNA interference technology was used to silence the expression of AMPK in macrophages, and the expression of TGF-β protein was subsequently examined by Western blot. RESULTS: LPS significantly reduced the expression of CD206 and increased the expression of CD11c (P <0.05). After the addition of PRP, the expression of CD206 was significantly increased (P <0.05), while the expression of CD11c was significantly decreased (P <0.05). Compared with LPS group, PRP treatment significantly increased the expressions of p-AMPK and p-ULK1 proteins at 12 h, 18 h and 24 h, while significantly decreased the expression of p-mTOR protein (P <0.05). After the addition of AMPK inhibitor Compound C, the expression of CD206 was significantly reduced (P <0.05) and the expression of CD11c was significantly increased compared with LPS+PRP group (P <0.05). After silencing the expression of AMPK in macrophages, the promotion effect of PRP on TGF-β was significantly reduced (P <0.05). CONCLUSION PRP can stimulate the transformation of macrophages to M2 type via AMPK signalling pathway.

Objective: To understand the current status of diagnosis and treatment of chronic lymphocytic leukemia (CLL) /small lymphocytic lymphoma (SLL) among hematologists, oncologists, and lymphoma physicians from hospitals of different levels in China. Methods: This multicenter questionnaire survey was conducted from March 2021 to July 2021 and included 1,000 eligible physicians. A combination of face-to-face interviews and online questionnaire surveys was used. A standardized questionnaire regarding the composition of patients treated for CLL/SLL, disease diagnosis and prognosis evaluation, concomitant diseases, organ function evaluation, treatment selection, and Bruton tyrosine kinase (BTK) inhibitor was used. Results: ①The interviewed physicians stated that the proportion of male patients treated for CLL/SLL is higher than that of females, and the age is mainly concentrated in 61-70 years old. ②Most of the interviewed physicians conducted tests, such as bone marrow biopsies and immunohistochemistry, for patient diagnosis, in addition to the blood test. ③Only 13.7% of the interviewed physicians fully grasped the initial treatment indications recommended by the existing guidelines. ④In terms of cognition of high-risk prognostic factors, physicians' knowledge of unmutated immunoglobulin heavy-chain variable and 11q- is far inferior to that of TP53 mutation and complex karyotype, which are two high-risk prognostic factors, and only 17.1% of the interviewed physicians fully mastered CLL International Prognostic Index scoring system. ⑤Among the first-line treatment strategy, BTK inhibitors are used for different types of patients, and physicians have formed a certain understanding that BTK inhibitors should be preferentially used in patients with high-risk factors and elderly patients, but the actual use of BTK inhibitors in different types of patients is not high (31.6%-46.0%). ⑥BTK inhibitors at a reduced dose in actual clinical treatment were used by 69.0% of the physicians, and 66.8% of the physicians had interrupted the BTK inhibitor for >12 days in actual clinical treatment. The use of BTK inhibitors is reduced or interrupted mainly because of adverse reactions, such as atrial fibrillation, severe bone marrow suppression, hemorrhage, and pulmonary infection, as well as patients' payment capacity and effective disease progression control. ⑦Some differences were found in the perceptions and behaviors of hematologists and oncologists regarding the prognostic assessment of CLL/SLL, the choice of treatment options, the clinical use of BTK inhibitors, etc. Conclusion: At present, a gap remains between the diagnosis and treatment of CLL/SLL among Chinese physicians compared with the recommendations in the guidelines regarding the diagnostic criteria, treatment indications, prognosis assessment, accompanying disease assessment, treatment strategy selection, and rational BTK inhibitor use, especially the proportion of dose reduction or BTK inhibitor discontinuation due to high adverse events.

As a recognized rare and highly fatal disease, hereditary angioedema (HAE) is difficult to diagnose and characterized by recurrent edema involving the head, limbs, genitals and larynx, etc. Diagnosis of HAE is not difficult. However, low incidence and lack of clinical characteristics lead to difficulty of doctors on timely diagnosis and correct intervention for HAE patients. Therefore, it is crucial to improve the awareness of this disease and prevent its recurrence. for HAE patients. In view of absent cognition of doctors and the general public on HAE, patients often suffer from sudden death or become disabled due to laryngeal edema which cannot be treated in time. Thus, based on the Internet mobile terminal platform, the team set up an all-day rapid emergency response system which is provided for HAE patients by setting up "one-click help". The aim is to offer optimization on overall management of HAE and designed the intelligent follow-up management to provide timely assistance and specialized suggestion for patients with acute attacks.

Allergic diseases affect about 40% of the world's population. Environmental factors are important in the occurrence and development of allergic diseases. Dust mites are one of the most important allergens in the indoor environment. The World Health Organization proposes the "four-in-one, combination of prevention and treatment" treatment principle for allergic diseases, in which environmental control to avoid or reduce allergens is the first choice for treatment. Modern people spend much more time at home (including sleeping) than outdoors, and the control of the home environment is particularly critical. This practice introduces the hypoallergenic home visit program, which including home environment assessment, environmental and behavioral intervention guidance, and common household hypoallergenic supplies and service guidance for the patient's home environment. The real-time semi-quantitative testing of dust mite allergens, qualitative assessments of other indoor allergens, record of patients' household items and lifestyle, and precise, individualized patient prevention and control education will be conducted. The hypoallergenic home visit program improves the doctors' diagnosis and treatment data dimension, and becomes a patient management tool for doctors outside the hospital. It also helps patients continue to scientifically avoid allergens and irritants in the environment, effectively build a hypoallergenic home environment, reduce exposure to allergens in the home environment, and achieve the goal of combining the prevention and treatment of allergic diseases.

ObjectiveTo investigate the causes of discontinuation of subcutaneous allergen immunotherapy （SCIT） in patients with allergic rhinitis （AR） and / or bronchial asthma （BA） in the Pearl River Delta region， and to improve the compliance of these patients. MethodsIt was a retrospective， multi-center real world study. Patients with AR and / or BA receiving SCIT in six hospitals in the Pearl River Delta region from January 2015 to December 2020 were recruited. The clinical data of all patients were collected， and the patients with abscission were followed up by telephone. ResultsIn this study， 1 244 patients who received SCIT were included. A total of 427 patients stopped SCIT before 3 years （34.3%）. Children， married patients and patients with positive family history of allergy and total immunoglobulin E （tIgE） > 200 U / mL showed relatively good compliance （P<0.05）， while more patients of AR alone stopped SCIT before 3 years than patients of AR complicated with BA （P<0.05）. Patients with high symptom score and drug score before treatment had better compliance （P<0.001）. A total of 279 cases （65.3%） of the non-adherence group were followed by telephone. The first three reasons for discontinuing treatment were the treatment did not achieve the expected effect （115 cases， 41.2%）， factors pertaining to learning and daily life （74 cases， 26.5%） and adverse reactions （29 cases， 10.4%）. The number of patients stopping SCIT decreased gradually with time； the proportion of patients who discontinued treatment due to adverse reactions in the first year of treatment was higher than that in the second and third years （P<0.05）. ConclusionFailure to achieve the expected effect was the primary reason for poor compliance of patients receiving SCIT and discontinuation mainly occurred on the early stage of the treatment. The supervision from family members is helpful to improve the compliance， suggesting that individualized measures need to be taken to reduce the loss of SCIT.

Objective: To expore the correlation between neck disability, neck pain and muscle strength in cervical pondylosis of office worker, and to provide scientific basis for the prevention and treatment of cervical spondylosis. Methods: In April 2021 ,234 patients with cervical spondylotic myelopathy treated in the Subsidiary Rehabilitation Hospital of Fujian University of Traditional Chinese Medicine from April 2015 to April 2017 were selected, the correlation between Neck Disability Index (NDI) score, neck pain and muscle strength was analyzed using the Spearman rank correlation method. Mann-Whitney U test was used to compare the difference of maximum muscle strength of isometric contraction. Results: NDI score was negatively correlated with neck flexion, extension, and muscle strength in the left and right flexion directions (r(s)=-0.164, -0.169, -0.222, -0.176, P=0.012, 0.010, 0.001 , 0.007). In mild and moderate functional disorder patients, the muscle strength in flexion, extension and left and right flexion direction was greater, the difference was statistically significant (P <0.01). Conclusion: There is a negative correlation between cervical functional disorder and cervical muscle strength in office workers, suggesting that strengthening cervical muscle strength may be a way to improve cervical spine function.
