Efficacy and adverse reactions of donepezil:a pharmacogenomic study / 中华老年心脑血管病杂志

Objective To analyze the efficacy and adverse reactions of donepezil in the treatment of patients with a continuous disease spectrum of Alzheimer's disease(AD)with pharmacogenomics.Methods Seventy-two patients who took donepezil therapy at the time of initial molecular pa-thology diagnosis of AD continuous disease spectrum in Chinese PLA General Hospital from Jan-uary 2022 to January 2023 were recruited.Cells from the oral buccal mucosa were collected,and MassARRAY nucleic acid mass spectrometry was applied to detect the genotypes of CYP2D6,the gene encoding cytochrome P450 2D6 enzyme,and CHAT,the gene encoding acetylcholine trans-ferase.After 9 months of follow-up,drug efficacy was indirectly determined by neurological func-tion scales,caregiver evaluations,and drug prescribing behaviors,and thus,the 50 patients on donepezil alone were divide into effective group(n=28)and ineffective group(n=22).Seventy-two patients were divided into adverse reaction group(n=12)and no adverse reaction group(n=60).Multivariate logistic regression analysis was used to analyze the correlation between donepezil efficacy and pharmacogenomics.Results The frequencies of CHAT rs3793790 locus carrying G allele and rs2177370 locus carrying A allele were significantly higher in the effective group than the ineffective group(35.71％vs 9.09％,P=0.029;42.86％vs 9.09％,P=0.008).Multivariate lo-gistic regression analysis showed that donepezil was more effective in those who carrying rs3793790 G allele and/or rs2177370 A allele in the CHAT gene than those who carrying neither of the alleles(95％CI:1.20-34.47,P=0.030).There were no statistical differences in the CYP2D6 gene-adjusted activity score and whether or not carrying*10 between the patients with and without adverse reactions(P＞0.0 5).Conclusion In patients with a continuous spectrum of AD,donepezil efficacy is associated with CHAT gene polymorphisms,but there is no correlation between donepezil adverse reactions and CYP2D6 genotype.

Relationships of Low Serum Levels of Interleukin-10 With Poststroke Anxiety and Cognitive Impairment in Patients With Clinical Acute Stroke

Background@#and Purpose The relationships among interleukin (IL)-10 levels, anxiety, and cognitive status after stroke remain controversial. We aimed to determine the associations of serum IL-10 levels with poststroke anxiety (PSA) and poststroke cognitive impairment (PSCI). @*Methods@#We recruited 350 patients with stroke, of whom only 151 completed a 1-month follow-up assessment. The Mini Mental State Examination (MMSE) and Hamilton Anxiety Scale (HAMA) were used to assess the cognitive status and anxiety, respectively. Serum IL-10 levels were measured within 24 hours of admission. @*Results@#IL-10 levels were significantly lower in the PSA group than in the non-PSA group, and they were negatively associated with HAMA scores (r=-0.371, p<0.001). After adjusting for all potential confounders, IL-10 levels remained an independent predictor of PSA (odds ratio=0.471, 95% confidence interval=0.237–0.936, p=0.032). IL-10 levels were strongly correlated with behavior during interviews, psychic anxiety, and somatic anxiety. Patients without PSCI had higher IL-10 levels were higher in non-PSCI patients than in PSCI patients, and they were positively associated with MMSE scores in the bivariate correlation analysis (r=0.169, p=0.038), and also with memory capacity, naming ability, and copying capacity.However, IL-10 did not predict PSCI in the univariable or multivariable logistic regression. @*Conclusions@#Low IL-10 levels were associated with increased risks of PSA and PSCI at a 1-month follow-up after stroke. Serum IL-10 levels may therefore be helpful in predicting PSA.

Let -7i : A key player and a promising biomarker in diseases / 中南大学学报(医学版)

MicroRNAs (miRNAs) are endogenous non-coding single-stranded small RNAs that regulate gene expression by recognizing homologous sequences and interfering with transcriptional, translational or epigenetic processes. MiRNAs are involved in a variety of disease processes, and regulate the physiological and pathological status of diseases by modulating target cell activity, migration, invasion, apoptosis, autophagy and other processes. Among them, let-7i is highly expressed in various systems, which participates in the process of tumors, cardiovascular and cerebrovascular diseases, fibrotic diseases, inflammatory diseases, neurodegenerative diseases and other diseases, and plays a positive or negative regulatory role in these diseases through different signal pathways and key molecules. Moreover, it can be used as an early diagnosis and prognostic marker for a variety of diseases and become a potential therapeutic target. As a biomarker, let-7i is frequently tested in combination with other miRNAs to diagnose multiple diseases and evaluate the clinical treatment or prognosis.

Evidence Map of Clinical RCT Studies on the Intervention of Diabetic Peripheral Neuropathy by Traditional Chinese Medicine in Recent Ten Years / 世界科学技术-中医药现代化

Objective To systematically retrieve and integrate the clinical randomized controlled trials(RCTs)and systematic reviews/Meta-analyses of traditional Chinese medicine in the treatment of diabetic peripheral neuropathy(DPN)in recent 10 years,aiming to summarize the overall evidence distribution of traditional Chinese medicine in the treatment of DPN.Methods CNKI,WANFANG,VIP,CBM,PubMed,Web of Science,Embase and the Cochrane Library were used as retrieval database.The retrieval time was from January 1,2012 to October 23,2022.RCTs and systematic reviews/Meta-analyses were included.The distribution of evidence was displayed in the form of charts.AMSTAR-1 was used for the methodological quality evaluation of systematic reviews/Meta-analyses.Results A total of 1648 RCTs and 59 systematic reviews/Meta-analyses were included.The overall number of RCTs were on the rise,but most of the scale of the RCTs were relatively small,with 68％of the samples size of a single study concentrated between 50-100;The Duration of intervention was 4-8 weeks;Multi-therapy was the most commonly used intervention,among which the most involved intervention was the combination of TCM decoction;Traditional Chinese medicine monotherapy was mainly oral traditional Chinese medicine decoction.The evaluation indexes of clinical efficacy paid much attention to the total effective rate,nerve conduction velocity,TCM diseases and syndromes;economic index,quality of life,long-term efficacy and other indicators had attracted less attention of researchers.The overall methodological quality of systematic reviews/Meta-analyses was not high,most of which show good clinical efficacy,but lack sufficient evidence support.Conclusion The research results show that the treatment of diabetes peripheral neuropathy with TCM have good characteristics and advantages,the shortcomings are mainly reflected in the low quality of the overall methodology of systematic reviews/Meta-analyses.Suggesting that more high-quality clinical RCTs with breadth and depth are still needed in the future to verify the characteristics and advantages of traditional Chinese medicine in the treatment of diabetic peripheral neuropathy and provide data information support for evidence-based medicine.

Analysis of the clinical characteristics and misdiagnosis of area postrema syndrome manifesting as intractable nausea, vomiting, and hiccups in neuromyelitis optica spectrum disorders / 中华内科杂志

Objective: To investigate the misdiagnosis of area postrema syndrome (APS) manifesting as intractable nausea, vomiting and hiccups in neuromyelitis optic spectrum disease (NMOSD) and reduce the risk of misdiagnosis. Methods: We retrospectively analyzed data from NMOSD patients attending the Department of Neurology at the First Medical Center of PLA General Hospital between January 2019 and July 2021. SPSS25.0 was then used to analyze the manifestations, misdiagnosis, and mistreatment of APS. Results: A total of 207 patients with NMOSD were included, including 21 males and 186 females. The mean age of onset was 39±15 years (range: 5-72 years). The proportion of patients who were positive for serum aquaporin 4 antibody was 82.6% (171/207). In total, 35.7% (74/207) of the NMOSD patients experienced APS during the disease course; of these patients, 70.3% (52/74) had APS as the first symptom and 29.7% (22/74) had APS as a secondary symptom. The misdiagnosis rates for these conditions were 90.4% (47/52) and 50.0% (11/22), respectively. As the first symptom, 19.2% (10/52) of patients during APS presented only with intractable nausea, vomiting and hiccups; 80.8% (42/52) of patients experienced other neurological symptoms. The Departments of Gastroenterology and General Medicine were the departments that most frequently made the first diagnosis of APS, accounting for 54.1% and 17.6% of patients, respectively. The most common misdiagnoses related to diseases of the digestive system and the median duration of misdiagnosis was 37 days. Conclusions: APS is a common symptom of NMOSD and is associated with a high rate of misdiagnosis. Other concomitant symptoms often occur with APS. Gaining an increased awareness of this disease/syndrome, obtaining a detailed patient history, and performing physical examinations are essential if we are to reduce and avoid misdiagnosis.

Evaluation of methodological and reporting quality of domestic clinical guidelines for hyperuricemia / 中国中药杂志

This study aims to evaluate the methodological and reporting quality of diagnosis and treatment guidelines for hyperuricemia as well as the expert consensuses and promote the understanding and application of the diagnosis and treatment guidelines for hyperuricemia. With "hyperuricemia" "guidelines" "consensus" "recommendations" as the key words in titles, the authors searched for the published clinical guidelines on hyperuricemia in Chinese against CNKI, Wanfang, VIP, Medlive and the official website of the industry association. The retrieval time limit was until May 31, 2021. The appraisal of guidelines for research and evaluation Ⅱ(AGREEⅡ) and the reporting items for practice guidelines in health care(RIGHT) were employed to evaluate the methodological quality and reporting quality of 14 guidelines/consensuses included. The average scores of the guidelines/consensuses were 80.85%(48.61%-98.61%) for the domain of scope and purpose, 34.52%(0-69.44%) for the domain of stakeholder involvement, 35.53%(6.25%-92.19%) for the domain of rigor of development, 55.85%(23.61%-86.11%) for the domain of clarity of presentation, 26.19%(0-76.04%) for the domain of applicability, and 21.42%(0-50.00%) for the domain of editorial independence. Nine guidelines/consensuses were of medium overall quality with grade B recommendation, and five guidelines/consensuses were of poor quality with grade C recommendation. The RIGHT classified the fourteen guidelines/consensuses into one of high reporting quality, three of medium reporting quality, and ten of low reporting quality. The results of this study indicate that the standardization and rigor of the methodological quality and the reporting quality of the clinical guidelines/consensuses for hyperuricemia in China remain to be strengthened.

Umbilical Cord Mesenchymal Stem Cells for Inhibiting the Fibrosis and Autoimmune Development in HOCl-Induced Systemic Scleroderma Mouse Model

Background and Objectives@#Systemic scleroderma (SSc) is a rare and serious connective tissue disease, an autoimmune disease, and a rare refractory disease. In this study, preventive effect of single systemic human umbilical cord mesenchymal stem cells (UC-MSCs) transfusion on SSc was preliminarily explored. @*Methods@#and Results: SSc mouse model was established by daily intradermal injection of Hypochlorite (HOCl). SSc mice were treated by single transfusion of UC-MSCs at 0.625×10 5 , 2.5×105 and 1×106 respectively. At the 42nd day of intradermal injection of HOCl, the symptoms showed up by skin and alveolar wall thickening, lymphocytic infiltration, increased collagen in skin/lung, and the increased proportion of CD3 ＋ CD4＋ CD25＋ FoxP3＋ cells (a Treg subset) in spleen. After UC-MSCs transfusion, the degree of skin thickening, alveolar wall thickening and lymphocyte infiltration were decreased, the collagen sedimentation in skin/lung was decreased, and the proportion of CD3＋ CD4＋ CD25＋FoxP3＋ cells was decreased. @*Conclusions@#UC-MSC can achieve a preventive effect in SSc mice by fibrosis attenuation and immunoregulation.

Endovascular recanalization for non-acute internal carotid artery occlusion using a new angiographic classification / 中华放射学杂志

Objective:To evaluate the safety and feasibility of endovascular recanalization for non-acute internal carotid artery occlusion (NA-ICAO), and to propose a new angiographic classification.Methods:From April 2015 to October 2019, 95 consecutive patients with symptomatic NA-ICAO who received endovascular recanalization were retrospectively analyzed in Beijing Tiantan Hospital, Capital Medical University. All the patients were divided into four groups according to DSA: type Ⅰ, petrous segments were distally reconstituted by collateral vessels; type Ⅱ, cavernous segments were distally reconstituted by collateral vessels; type Ⅲ, ophthalmic segments were distally reconstituted by collateral vessels; type Ⅳ, communicating segments were distally reconstituted by collateral vessels. Study data including clinical characteristics, surgical details, lesion classification, recanalization rate and perioperative complications. For the counting data, the χ 2 test was used to compare between groups. For the quantitative data, the ANOVA was used for the normal distribution data, otherwise the Kruskal-Wallis H test was used. The primary safety outcome was any stroke or death within 30 days. Results:Among the 95 patients, 67 (70.53%) had successful recanalization. The recanalization rates of type Ⅰ－Ⅳ were 92.31% (36/39), 81.82% (18/22), 47.83% (11/23) and 18.18% (2/11) respectively (χ2=29.557, P<0.001). And the complication rates of the four types were 5.13% (2/39), 13.64% (3/22), 21.74% (5/23) and 9.10% (1/11) respectively. The incidence of perioperative ischemic stroke was 2.11% (2/95). No other serious stroke and death occurred. Conclusions:Endovascular recanalization may be feasible and safe for carefully selected patients with NA-ICAO and therefore represents an alternative treatment. The patients with type Ⅰ and Ⅱ lesions had higher recanalization rates, while the patients with type Ⅳ lesions had significantly lower recalculation rate. The new angiographic classification is conducive to the selection of suitable patients and difficulty in grading.

A novel diffusion-weighted imaging-based posterior circulation score for prediction of futile recanalization in acute basilar artery occlusion / 中华神经科杂志

Objective:To develop a novel posterior circulation score (PCS) based on pretreatment diffusion-weighted imaging (DWI) for predicting futile recanalization (FR) of acute basilar artery occlusion (BAO) after endovascular therapy (EVT).Methods:A prospectively registered consecutive cohort of BAO patients treated with EVT in Beijing Tiantan Hospital, Capital Medical University during a six-year period was reviewed. This novel DWI-based PCS (DWI-PCS) was calculated according to the characteristics of acute infarction at four sites (pons, midbrain, thalamus and cerebellum), with a normal score of 0 point and a full score of 16 points. FR was defined as the occurrence of poor outcome (modified Rankin Scale score>3) at 90 days despite successful recanalization (modified Thrombolysis In Cerebral Infarction ≥ 2b) at final angiogram after EVT. The independent association of DWI-PCS with FR was evaluated by multivariable Logistic regression, and the predictive discrimination of DWI-PCS was measured by the area under the receiver operating characteristic (ROC) curve. Additionally, the effects of DWI-PCS on FR in different subgroups stratified by age, time window, stroke severity and etiology were explored.Results:Of 109 patients in this study, 48 (44.0%) suffered from FR. The multivariable Logistic analysis showed that DWI-PCS was significantly associated with FR (adjusted OR=1.31, 95% CI 1.07-1.62, P=0.01). The ROC curve analysis demonstrated that the area under the curve of DWI-PCS for predicting FR was 0.74 (95% CI 0.65-0.83), and the optimal cut-off value was ≥ 3 points (sensitivity 0.75, specificity 0.66, accuracy 0.70). Finally, the effects of DWI-PCS on FR were not found to be different across all subgroups ( P>0.10 for all interactions). Conclusions:The novel DWI-PCS may be a valid and reliable predictor of FR in BAO patients treated with EVT. Nevertheless, external validation with blinded outcome is still needed to confirm its performance before clinical application.

Relationship between subjective well-being and anxiety of nurses in a hospital / 中国职业医学

OBJECTIVE: To investigate the current status of subjective well-being(SWB) and anxiety of nurses, and analyze their correlation. METHODS: A total of 1 052 nurses from an A-Class hospital in Wuhan City were recruited as the study subjects by convenience sampling method, and the SWB and anxiety survey were conducted using the Overall Happiness Scale and Anxiety Self-Rating Scale. RESULTS: The median score of SWB in the study subjects was 64.0, which is at the intermediate level; the median anxiety score was 54.0, and 64.5% of anxiety was mild or above. There was a negative correlation between SWB and anxiety(Spearman correlation coefficient was-0.72, P<0.01). The results of multiple linear regression analysis showed that the nurses who had more anxiety were accompanied with lower SWB(P<0.05); the SWB was lower in divorced nurses than that in married or unmarried ones(P<0.05); the SWB was higher in nurses who work in obstetrics and gynecology than that in internal medicine(P<0.05).CONCLUSION: The SWB of nurses in this A-Class hospital is relatively low, and most of them have anxiety, which has a negative effect on SWB.

Anti‐SOX1 Antibodies in Paraneoplastic Neurological Syndrome

Anti-Sry-like high mobility group box (SOX) 1 antibodies (abs) are partly characterized onconeural autoantibodies (autoabs) due to their correlation with neoplastic diseases. AntiSOX1 abs are associated with various clinical manifestations, including Lambert-Eaton myasthenic syndrome (LEMS) and paraneoplastic cerebellar degeneration (PCD). However, the clinical characteristics of patients with anti-SOX1 abs have not been described in detail. This review systematically explores the reported patients with anti-SOX1 abs and analyzes these cases for demographic characteristics, clinical features, coexisting neuronal autoabs, neuroimaging findings, treatment, and clinical outcomes. In addition, considering that PCD is the most common paraneoplastic neurological syndrome and that the association between PCD and anti-SOX1 abs remains unclear, we focus on the presence of autoabs in relation to PCD and associated tumors. PCD-associated autoabs include various intracellular autoabs (e.g., anti-Hu, anti-Yo, anti-Ri, and anti-SOX1) and cell-surface autoabs (anti-P/Q-type voltage-gated calcium channel). Commonly involved tumors in PCD are small-cell lung cancer (SCLC), gynecological, and breast tumors. LEMS is the most common clinical symptom in patients with antiSOX1 abs, followed by PCD, and multiple neuronal autoabs coexist in 47.1% of these patients.SCLC is still the predominant tumor in patients with anti-SOX1 abs, while non-SCLC is uncommon. No consistent imaging feature is found in patients with anti-SOX1 abs, and there is no consensus on either the therapy choice or therapeutic efficacy. In conclusion, the presence of anti-SOX1 abs alone is a potential predictor of an uncommon paraneoplastic neurological disorder, usually occurring in the setting of LEMS, PCD, and SCLC. The detection of anti-SOX1 abs contributes to an early diagnosis of underlying tumors, given the diversity of clinical symptoms and the absence of characteristic neuroimaging features.

A comparative analysis of bridging therapy versus direct endovascular treatment in acute ischemic stroke patients aged 80 years and over / 中华老年医学杂志

Objective:To compare the safety and therapeutic effect of bridging therapy versus direct endovascular treatment in patients with acute ischemic stroke(AIS)aged 80 years and over, who received the therapy within 4.5 h of onset.Methods:A total of 89 AIS patients aged 80 years and over receiving the endovascular therapy at our hospital from January 2016 to June 2019 were studied with versus without intravenous thrombolysis before endovascular therapy(the former as bridging therapy group, n=49; the latter as the direct endovascular treatment group, n=40). Baseline information including gender, the modified Rankin scale(mRS)score, medical history, smoking history, preoperative national institute of health stroke scale(NIHSS)score were collected.Clinical data related to the operation including the times from onset to hospital, door-to-puncture and door-to-recanalization, complications(symptomatic cerebral hemorrhage, mortality)and mRS at 90 d after treatment were compared between the two groups.Multiple logistic regression analysis was used to determine whether or not bridging therapy with intravenous thrombolysis was a prognostic factor.Results:There was no significant difference in baseline information between the two groups( P>0.05). The times from onset to hospital, door-to-puncture, door-to-recanalization had no significant difference between the two groups( P>0.05). There was no significant difference in the incidence of symptomatic cerebral hemorrhage and mortality within 90 d between the two groups(26.5% or 13 cases vs. 17.5% or 7 cases, 14.3% or 7 cases vs.7.5% or 3 cases, χ2=1.031 and 1.017, P=0.310 and 0.313). With different clinical outcomes as dependent variables, after adjusting factors such as gender, admission NIHSS and medical history, Logistic regression analysis showed that the bridging therapy with intravenous thrombolysis was not a prognostic factor( OR=0.795, 95% CI: 0.280~2.258, P=0.666). Conclusions:The bridging therapy is as safe and effective as the direct intravascular therapy for AIS patients aged 80 and over within 4.5 hours of onset.The intravenous thrombolysis should be given as soon as possible within time window.

Clinical analysis of carbapenem-resistant klebsiella pneumoniae-induced neonatal sepsis / 中国新生儿科杂志

Objective To study the clinical feature of carbapenem-resistant klebsiella pneumoniae (CRKP) neonatal sepsis.Method From January 2012 to December 2017,clinical data of newborns with klebsiella pneumoniae (Kp) sepsis admitted to the NICU of our hospital were retrospectively analyzed.Clinical manifestations,laboratory examinations,risk factors,treatments and outcomes were compared between newborns with CRKP sepsis and newborns with carbapenem-sensitive klebsiella pneumoniae (CSKP) sepsis.Result A total of 71 strains of Kp were isolated,representing 33.2％ of all isolated pathogens (71/214).Among 71 newborns diagnosed with Kp sepsis,35 were CRKP sepsis and the other 36 were CSKP sepsis.The incidence of dyspnea/apnea in CRKP group was significantly higher than CSKP group (85.7％ vs.55.6％,P=0.005).Newborns in CRKP group had smaller gestational age than CSKP group.The proportions of male gender,the incidences of continuous positive airway pressure treatment,parenteral nutrition and antibiotics exposure (cephalosporins,penicillins or carbapenems) before the onset of sepsis in CRKP group were higher than CSKP group and the hospital stay before sepsis was longer than CSKP group,the differences were statistically significant (P＜0.05).Logistic regression analysis showed that male gender (OR=8.125,95％CI 2.275～29.021),parenteral nutrition (OR=27.730,95％CI 2.948～260.858) and carbapenems exposure before onset (OR=4.849,95％CI 1.091～21.554) were independent risk factors of neonatal CRKP sepsis (P＜0.05).The mortality rate of CRKP group was higher than the CSKP group (22.9％ vs.5.6％,P=0.036).Conclusion Male,parenteral nutrition and carbapenems exposure before onset were independent risk factors of neonatal CRKP sepsis.CRKP sepsis is critical and has a high mortality rate.Clinicians should monitor drug resistance carefully,follow antibiotics stewardship principles and establish enteral nutrition as soon as possible.

Characteristics of cognitive function in silent lacunar cerebral infarction patients with white matter hyperintensities / 中华老年心脑血管病杂志

Objective To study the association between white matter hyperintensities(WMH)and cognitive function in silent lacunar cerebral infarction patients and its risk factors.Methods One hundred and seventy-four silent lacunar cerebral infarction patients were included in this study. They underwent MRI to show the site and severity of their WMH,including degrees 0-3of periventricular WMH in 21,102,39,12patients respectively,and deep WMH in 19,53,86,16patients respectively.Then,their cognitive function scores were compared.Results The degree of WMH was significantly higher and the age was significantly older in silent lacunar cerebral infarction patients(P＜0.05).The situation memory,working memory and Simplified Intelligent State Scale score were significantly different in patients with different degrees of WMH in peripheral brain(P＜0.05,P＜0.01).The working memory was significantly different in patients with different degrees of WMH in deep brain(P＜0.05).Degrees 1and 2of periventricular WMH were the independent risk factors for the impaired working memory(β=-0.264,P=0.038;β=-0.325,P=0.011)while degree 3of periventricular WMH was the independent risk factor for the impaired cognitive function(β=-0.273,P=0.014).Conclusion The memory is easy to be impaired in silent lacunar cerebral infarction patients with WMH of aging brain.Periventricular WMH is the major risk factor for cognitive impairment.
