ABSTRACT
Objective: To screen the differential methylation sites, genes and pathways of air pollution fine particles (PM(2.5)) on human bronchial epithelial (HBE) cells by methylation chip and bioinformation technology, so as to provide scientific basis for further study of the toxicological mechanism of PM(2.5) on HBE cells. Methods: In August 2020, HBE cells were infected with 10 μg/ml and 50 μg/ml PM(2.5) aqueous solution for 24 h, namely PM(2.5) 10 μg/ml exposure group (low dose group) and PM(2.5) 50 μg/ml exposure group (high dose group) ; uninfected HBE cells were used as control group. The DNA fragments were hybridized with the chip, the chip scanned and read the data, analyzed the data, screened the differential methylation sites, carried out GO analysis and KEGG analysis of the differential methylation sites, and analyzed the interaction relationship of the overall differential methylation sites by functional epigenetic modules (FEMs). Results: Compared with the control group, 127 differential methylation sites were screened in the low-dose group, including 89 genes, including 55 sites with increased methylation level and 72 sites with decreased methylation level. The differential methylation sites were mainly concentrated in the Body region and UTR region. Compared with the control group, 238 differential methylation sites were screened in the high-dose group, including 168 genes, of which 127 sites had increased methylation level and 111 sites had decreased methylation level. The differential heterotopic sites were mainly concentrated in the Body region and UTR region. Through FEMs analysis, 8 genes with the most interaction were screened, of which 6 genes had significant changes in methylation level. MALT1 gene related to apoptosis was found in the heterotopic site of methylation difference in low-dose group; PIK3CA and ARID1A genes related to carcinogenesis were found in the heterotopic sites of methylation difference in high-dose group; TNF genes related to tumor inhibition were found in the results of FEMs analysis. Conclusion: After PM(2.5) exposure to HBE cells, the DNA methylation level is significantly changed, and genes related to apoptosis and carcinogenesis are screened out, suggesting that the carcinogenic mutagenic effect of PM(2.5) may be related to DNA methylation.

Objective:To investigate the value of contrast-enhanced ultrasound (CEUS) in the diagnosis of malignant endometrial lesions.Methods:A total of 142 patients with endometrial lesions who underwent contrast-enhanced ultrasound examination in Beijing Tiantan Hospital, Capital Medical University from January 2019 to September 2021 were selected. The endometrial lesions were divided into benign group (including endometrial hyperplasia and endometrial polyps) and malignant group (endometrial cancer) according to the pathological results of surgery, and the differences of contrast enhancement patterns between benign group and malignant group were compared. The sensitivity, specificity of CEUS in the diagnosis of endometrial cancer were calculated, and the Kappa value was calculated with the initial enhancement time earlier than or equal to the muscularity or the peak time earlier than the muscularity as the diagnostic index for the diagnosis of endometrial malignant lesions. The sensitivity, specificity, and Kappa value of CEUS in the diagnosis of endometrial cancer and endometrial cancer with thickness ≥10 mm were calculated.Results:A total of 108 patients underwent surgery with clear pathological results, including 66 patients in the benign lesion group and 42 patients in the malignant lesion group. The thickness of malignant lesions was significantly larger than that of benign lesions, and the difference was statistically significant( t=4.039, P<0.05), but there was no significant difference of hemodynamic parameters between the two groups ( P>0.05). The initial enhancement time, peak time and peak intensity of benign lesions were significantly different from those of malignant lesions(all P<0.05). The sensitivity, specificity, and Kappa value of CEUS in the diagnosis of endometrial cancer were 64.3%, 100% and 0.668, respectively. The sensitivity, specificity and Kappa value of CEUS in the diagnosis of endometrial carcinoma with lesion thickness ≥10 mm were 75.0%, 100% and 0.795, respectively. Conclusions:For the diagnosis of endometrial lesions, especially the malignant endometrial lesions with thickness and diameter greater than or equal to 10mm, there is a high diagnostic coincidence rate between CEUS and pathological diagnosis, and endometrial malignant lesions have more specific CEUS manifestations.

Objective:To investigate the effect of the number of retrieval attempts on the outcomes after successful recanalization of mechanical thrombectomy in patients with acute ischemic stroke.Methods:Patients with acute large vessel occlusive ischemic stroke underwent mechanical thrombectomy and successful postoperative recanalization in the Stroke Center of Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from January 2019 to May 2020 were retrospectively enrolled. According to the number of retrieval attempts during the procedure, the patients were divided into <3-attempt group and ≥3-attempt group. The demographic data, procedure-related indexes, periprocedural complications and outcomes at 90 d after the procedure were compared between the two groups.Results:A total of 106 patients, aged 69.8±1.3 years, were enrolled, and 55 were males (51.9%). Eight-three patients (78.3%) were in the <3-attempt group, and 23 (21.7%) were in the ≥3-attempt group. Forty-one patients (38.7%) had good outcomes (the modified Rankin Scale score ≤2) at 90 d, and 11 (10.4%) died. There were no significant differences in the incidence of intracranial hemorrhage (30.4% vs. 20.5%; χ2=1.019, P=0.313), the good outcome rate at 90 d (34.8% vs. 39.8%; χ2=0.188, P=0.665) and mortality (8.7% vs. 10.8%; P=0.999) between the ≥3-attempt group and <3-attempt group, but the incidence of symptomatic intracranial hemorrhage was significantly higher than that in the <3-attampt group (13.0% vs. 1.2%; P=0.031). Multivariate logistic regression analysis showed that the number of retrieval attempts was not significantly associated with poor outcome. Conclusion:The more retrieval attempts may be related to symptomatic intracranial hemorrhage, but it does not affect the clinical outcomes of patients with successful recanalization at 3 months.
ABSTRACT
Thymic stromal lymphopoietin (TSLP), as a pleiotropic cell growth factor, not only participants in the processes of human skin fibrosis, epidermal proliferation and angiogenesis, but also plays a critical role in regulating a variety of immune cells in immune-related diseases (such as respiratory diseases and allergic diseases). TSLP regulates various innate immune cells (such as dendritic cells, mast cells, macrophages, eosinophils, basophils, natural killer T cells and innate lymphocytes) and adaptive immune cells (T lymphocytes and B lymphocytes) mainly through JAK/STAT, NF-κB and other signal pathways mediated by TSLP receptor. This paper summarized the progress in the regulatory roles of TSLP in the proliferation, differentiation and function of various immune cells.
ABSTRACT
OBJECTIVE@#To evaluate the safety and efficacy of BUCY (busulfan and cyclophosphamide) conditioning regimen for autologous hematopoietic stem cell transplantation (ASCT) in patients with multiple myeloma (MM).@*METHODS@#The clinical data of 72 MM patients received transplantation in the Hematology Department of the First Affiliated Hospital of Soochow University from May 2012 to June 2015 were retrospectively analyzed. Among them, 36 patients received BUCY conditioning regimen while the others received high-dose melphalan (HDM) conditioning regimen. The complication, post-transplantation hematopoietic reconstitution and efficacy between the two groups were compared.@*RESULTS@#There were no significant differences in sex, age, isotype, stage, induction therapy, mobilization method and proportion of conditioning regimen with Bortezomib between the two groups. The median time of neutrophil engraftment for the patients in BUCY and HDM groups was 10 (8-17) and 10 (9-13) d (P=0.046), and the median time of platelet engraftment was 10 (8-18) and 11 (9-47) d (P=0.017), respectively. The transplant related mortality of the patients in both groups was 2.7%. The CR rates of the patients after ASCT (38.9% and 50.0%) were higher than those before ASCT (27.8% and 19.4%) in the two groups. For the patients in BUCY group, the median follow-up time was 45 (0-61) months. Fifteen patients (41.7%) achieved disease progression. While for the patients in HDM group, the median follow-up time was 52(0-75) months. Twenty-two patients (61.1%) achieved disease progression.@*CONCLUSION@#The BUCY conditioning regimen is a safe and effective therapy for ASCT in patients with MM. Besides, in terms of safety and efficacy, BUCY regimen is not inferior to HDM regimen. BUCY regimen may replace HDM regimen as a standard conditioning regimen for ASCT in MM.

BACKGROUND@#The side effects of chemotherapy-induced nausea and vomiting (CINV) and myelosuppression reduce the cancer patients' adherence to chemotherapy. Many Chinese patients choose Chinese medicine (CM) during chemotherapy to reduce side effects; however, the evidence is lacking. The efficacy of a CM herbal treatment protocol, Jianpi Bushen Sequential Formula (, JBSF) will be evaluated on chemotherapy completion rate among patients with colon cancer.@*METHODS@#A multi-center double-blind randomized controlled trial (RCT) will be conducted on 400 patients with colon cancer who will receive 8 cycles of adjuvant chemotherapy with oxaliplatin and capecitabine (CAPEOX). Patients will be randomized 1:1 to receive the JBSF or placebo formula. The primary outcome is the overall chemotherapy completion rate. The secondary outcomes include individual chemotherapy completion rate, 4-cycle completion rate of chemotherapy, time to treatment failure, relative dose intensity and treatment toxicity. Follow-up visits will be scheduled before every and after last chemotherapy.@*DISCUSSION@#This study will provide evidence on whether JBSF can improve the chemotherapy completion rate and reduce side effects among patients with colon cancer. (Trial registration: ClinicalTrials.gov, No. NCT03716518).

Objectives: To evaluate the safety and efficacy of LuX-Valve on the treatment of severe tricuspid regurgitation (TR). Methods: This is a prospective observational study. From September 2018 to March 2019, 12 patients with severe TR, who were not suitable for surgery, received LuX-Valve implantation in Changhai Hospital. LuX-Valve was implanted under general anesthesia and the guidance of transesophageal echocardiography and X-ray fluoroscopy. Access to the tricuspid valve was achieved via a minimally invasive thoracotomy and transatrial approach. Main endpoints were surgery success and device success. Surgery success was defined as successful implanting the device and withdrawing the delivery system, positioning the valve correctly and stably without severe or life-threatening adverse events. Device success was defined as satisfied valve function (TR severity reduction ≥ 2 grades, tricuspid gradient ≤ 6 mmHg (1 mmHg=0.133 kPa)), absence of malposition, valve failure and reintervention, major adverse events including device related mortality, embolization, conduction system disturbances and new onset shunt across ventricular septum at day 30 post implantation. Results: A total of 12 patients with severe to torrential TR were included in this study. The age was (68.5±6.9) years and 7 were female. All patients had typical right heart failure symptoms. Procedural success was achieved in all cases, there was no intraprocedural mortality or transfer to open surgery. TR significantly improved after LuX-Valve implantation (none/trivial in 8 patients, mild in 3 patients and moderate in 1 patient). The average device time was (9.2±4.2) minutes. Intensive care unit duration was 3.0 (2.0, 4.8) days. One patient died at postoperative day 18 due to non-surgery and device reasons. Transthoracic echocardiography at 30 days after operation showed that TR was significantly reduced (none/trivial in 8 patients, mild in 2 patients and moderate in 1 patient) and device success was achieved in 11 cases. All survived patients experienced a significant improvement in life quality with significantly improvement in New York Heart Association (NYHA) classification (Ⅰ and Ⅱ: 6/11 post operation vs. 0/11 before operation, P=0.012) and there were no device related complications in this patient cohort. Conclusions: LuX-Valve implantation is feasible, safe and effective for the treatment of patients with severe TR.

Background@#and Purpose The rate of donepezil discontinuation and the underlying reasons for discontinuation in Asian patients with Alzheimer’s disease (AD) are currently unknown. We aimed to determine the treatment discontinuation rates in AD patients who had newly been prescribed donepezil in routine clinical practice in Asia. @*Methods@#This 1-year observational study involved 38 institutions in seven Asian countries, and it evaluated 398 participants aged 50–90 years with a diagnosis of probable AD and on newly prescribed donepezil monotherapy. The primary endpoint was the rate of donepezil discontinuation over 1 year. Secondary endpoints included the reason for discontinuation,treatment duration, changes in cognitive function over the 1-year study period, and compliance as assessed using a clinician rating scale (CRS) and visual analog scale (VAS). @*Results@#Donepezil was discontinued in 83 (20.9%) patients, most commonly due to an adverse event (43.4%). The mean treatment duration was 103.67 days in patients who discontinued. Among patients whose cognitive function was assessed at baseline and 1 year, there were no significant changes in scores on the Mini-Mental State Examination, Montreal Cognitive Assessment, and Trail-Making Test–Black and White scores, whereas the Clinical Dementia Rating score increased significantly (p<0.001). Treatment compliance at 1 year was 96.8% (306/316) on the CRS and 92.6±14.1% (mean±standard deviation) on the VAS. @*Conclusions@#In patients on newly prescribed donepezil, the primary reason for discontinuation was an adverse event. Cognitive assessments revealed no significant worsening at 1 year, indicating that continuous donepezil treatment contributes to the maintenance of cognitive function.

ABSTRACT
Objective:To investigate the predictors of early neurological deterioration (END) in patients with acute ischemic stroke (AIS) based on the Oxfordshire Community Stroke Project (OCSP) classification system.Methods:Patients with AIS admitted to the Department of Neurology, Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from February 2018 to November 2020 were enrolled retrospectively. According to the OCSP criteria, the patients were classified into total anterior circulation infarct (TACI), partial anterior circulation infarct (PACI), posterior circulation infarct (POCI), and lacunar infarct (LACI). END was defined as the National Institutes of Health Stroke Scale (NIHSS) total score within 72 h after onset increased by ≥2 or motor function score increased by ≥1 compared with the baseline. Multivariate logistic regression analysis was used to determine the independent risk factors for END in AIS patients with different OCSP types. Receiver operating characteristic (ROC) curve was used to analyze the predictive value of each index for END in AIS patients with different OCSP types. Results:A total of 405 patients with AIS were enrolled. Their age was 68.84±12.27 years, and 250 were males (61.7%); 132 patients (32.6%) were in the TACI group, 108 (26.7%) were in the PACI group, 61 (15.1%) were in the POCI group, and 104 (25.7%) were in the LACI group. END occurred in 136 patients (33.6%). Multivariate logistic regression analysis showed that homocysteine (Hcy) (odds ratio [ OR] 1.065, 95% confidence interval [ CI] 1.012-1.212; P=0.015), baseline NIHSS score ( OR 1.209, 95% CI 1.095-1.335; P<0.001) and the time from onset to admission ( OR 1.663, 95% CI 1.282-2.082; P<0.001) were significantly and independently correlated with END in the TACI group. Hcy ( OR 1.137, 95% CI 1.040-1.244; P=0.005), fasting blood glucose ( OR 1.714, 95% CI 1.272-2.311; P<0.001), neutrophil to lymphocyte ratio (NLR) ( OR 1.370, 95% CI 1.016-1.848; P=0.039) and the time from onset to admission ( OR 1.266, 95% CI 1.056-1.519; P=0.011) were significantly and independently correlated with END in the PACI group. NLR ( OR 1.446, 95% CI 1.031-2.027; P=0.033) was significantly and independently correlated with END in the POCI group. Fasting blood glucose ( OR 1.301, 95% CI 1.006-1.683; P=0.045), NLR ( OR 1.393, 95% CI 1.025-1.894; P=0.034) and the time from onset to admission ( OR 1.171, 95% CI 1.008-1.361; P=0.039) were significantly and independently correlated with END in the LACI group. ROC curve analysis showed that the areas under the curve (AUC) of Hcy and baseline NIHSS score for predicting END in the TACI group were 0.617 (95% CI 0.521-0.713; P=0.021) and 0.784 (95% CI 0.706-0.862; P<0.001). The optimal cut-off values were 15.91 μmol/L and 19.5 points, respectively. The sensitivity and specificity were 63.7% and 85.2%, 62.0% and 86.9%, respectively. The AUC of Hcy, fasting blood glucose and NLR for predicting END in the PACI group were 0.672 (95% CI 0.548-0.797; P=0.005), 0.794 (95% CI 0.697-0.891; P<0.001) and 0.674 (95% CI 0.560-0.788; P=0.005), respectively. The optimal cut-off values were 15.2 μmol/L, 6.85 mmol/L, and 3.71, respectively. The sensitivity and specificity were 61.3% and 77.9%, 80.6% and 72.8%, 67.7% and 79.4%, respectively. The AUC of NLR for predicting END in the POCI group was 0.850 (95% CI 0.735-0.964; P<0.001). The optimal cut-off value was 5.2. The sensitivity and specificity were 84.2% and 81.4% respectively. The AUC of fasting blood glucose and NLR for predicting END in the LACI group were 0.728 (95% CI 0.614-0.842; P<0.001) and 0.731 (95% CI 0.614-0.842; P<0.001), respectively. The optimal cut-off values were 5.44 mmol/L and 2.71 respectively. The sensitivity and specificity were 80.0% and 62.7%, 76.0% and 79.2%, respectively. Conclusion:The predictors of END in AIS patients with different OCSP types are different.

ABSTRACT
Objective:To screen out stable internal reference genes suitable for real-time quantitative polymerase chain reaction（Real-time PCR） analysis of different parts of<italic> Cinnamomum cassia</italic> and <italic>C. cassia</italic> var. <italic>macrophyllum</italic>，in order to provide stable internal reference genes for gene expression analysis of three different parts of and <italic>C. cassia</italic> var.<italic> macrophyllum</italic> branches and leaves. Method:With 6 different tissues and organs， such as bark，branches and leaves of two plants of <italic>C. cassia</italic> and <italic>C. cassia</italic> var. <italic>macrophyllum</italic> as experimental materials，Real-time PCR technology was used to detect the five internal reference genes， namely glyceraldehyde-3-phosphate dehydrogenase（GAPDH），actin，ubiquitin-ligase enzymes（UBE），histone and tubin（TUB）. The analysis of the expression of the data. Furthermore， three commonly used internal reference gene analysis software，namely geNorm，NormFinder and BestKeeper，was used to analyze and evaluate the stability of the candidate internal reference gene. Result:The internal five reference genes were expressed in the bark，branches and leaves of the two plants，but with differences in stability. Comprehensive analysis showed that the expression stability of candidate internal reference genes was in the order of GAPDH>actin>UBE>histone>TUB. The internal reference genes of the two plants were analyzed separately，and the optimal internal reference gene was still GAPDH，indicating that GAPDH was the most suitable internal reference gene. TUB and histone ranked low in the three software，and should be eliminated in the screening of reference genes. They were not suitable for gene expression analysis of <italic>C. cassia </italic>and <italic>C. cassia</italic> var. <italic>macrophyllum</italic>. Conclusion:The most suitable internal reference gene for different parts of cinnamon，branches，and leaves of <italic>C. cassia</italic> and <italic>C. cassia</italic> var. <italic>macrophyllum</italic> was GAPDH. In this study，a screening system for internal reference genes of Real-time PCR of <italic>C. cassia</italic> and <italic>C. cassia</italic> var. <italic>macrophyllum</italic> was established to provide theoretical basis for studying functional regulation and expression of genes during the accumulation of effective components in different parts.
ABSTRACT
Objective:To investigate the effects of iron sucrose combined with recombinant human erythropoietin(EPO)on perioperative anemia and early functional recovery in elderly patients with intertrochanteric fractures.Methods:A retrospective comparative analysis was performed on 78 elderly patients who received PFNA treatment for intertrochanteric fractures in our hospital from July 2016 to December 2018.In the observation group, 40 cases were treated with iron sucrose combined with erythropoietin during the perioperative period.No perioperative intervention measures were taken for the control group.Hemoglobin(Hb)levels at 1, 3, 5, 7 days and before discharge and Harris scores of hip joints before surgery, 2 weeks and 3 months after surgery were compared between the two groups.Results:Hb levels were higher in the observation group than in the control group at 5 d[(98.8±8.6 g/L vs.92.2±8.5 g/L, t=3.389, P=0.001)]and 7 d[(105.4±8.9)g/L vs.(94.8±8.5)g/L, t=5.370, P=0.000]after surgery and before discharge[(115.4±8.6)g/L vs.(100.6±8.2)g/L, t=7.771, P=0.000]. Harris scores were higher in the observation group than in the control group 3 months after surgery(82.4±3.8 vs.75.8±2.5, t=8.933, P=0.000). Pearson' s correlation analysis showed that Hb levels at 5d and 7d after surgery were positively correlated with Harris scores at 3 months after surgery.Hb levels before discharge had an effect on Harris scores at 3 months after surgery. Conclusions:The combined administration of iron sucrose and EPO perioperatively can promote postoperative Hb recovery, reduce the incidence of anemia, accelerate early functional recovery and improve the quality of life in elderly patients with intertrochanteric fractures.
ABSTRACT
Objective:To explore the application of group sandbox game intervention on emotional state and coping style in patients with gastric cancer.Methods:A total of 92 patients with gastric cancer treated with chemotherapy in the First People′s Hospital of Lianyungang from March 2018 to March 2019 were selected by convenient sampling method, they were divided into two groups according to admission time, 46 patients in the control group received conventional care after chemotherapy, and 46 patients in the observation group received group sandplay therapy for three months which was performed after chemotherapy. The Distress Thermometer(DT), Hamilton Depression Scale (HAMD), Hamilton Anxiety Scale (HAMA), Medical Copingmodes Questionnaire (MCMQ) were used to assess the emotional status and coping style of the patients before and after intervention.Results:After intervention, the DT, HAMA and HAMD scores of the observation group were 2.26±2.09, 13.52±2.50 and 16.47±3.61 respectively, and the DT, HAMA and HAMD scores of the control group were 3.36±2.23 and 20.85±4.53, 23.63±4.82, respectively. The DT, HAMA, HAMD scores in observation group were significantly lower than those in the control group, the difference between the two groups was statistically significant ( t value was 2.441, 9.608, 8.064, P<0.05). The dimensional score of the MCMQ measurement surface of the observation group after intervention was 18.35±3.19, and 14.25±3.04 in the control group. MCMQ scale escape and yield dimension scores in the observation group were 15.26±3.14, 10.24±2.56, and 17.81±2.59 and 12.84±2.64 in the control group. After the intervention, the observation group′s MCMQ surface score was higher than the control group, and the escape and yield dimension score was lower than that of the control group ( t value was 6.311, 4.249, 4.795, P<0.05). Conclusions:Group sandplay therapy can relieve negative emotion in patients with gastric cancer undergoing chemotherapy, and improve their coping style.
ABSTRACT
Objective:To investigate the correlation between the location and volume of cerebral microbleeds (CMBs) and lacunar infarction (LI) in patients with cerebral small vessel disease (CSVD).Methods:Participants from the CSVD cohort in the Department of Neurology, Nanjing Drum Tower Hospital, the Affiliated Hospital of Medical School of Nanjing University from February 2017 to March 2019 were enrolled retrospectively. All participants underwent magnetic resonance imaging scans, standardized clinical assessment and diagnosis. AccuBrain, an automatic brain segmentation and quantification software developed by the Chinese University of Hong Kong, was used to quantitatively analyze the volume of CMBs and white matter hyperintensities (WMHs). Ordered multi-class logistic regression analysis was used to determine the independent influencing factors of LI, and then multiple linear regression analysis was used to investigate the correlation between the volume of deep or infratentorial CMBs (DI-CMBs) and the number of LI. Results:A total of 317 patients with CSVD were included in the analysis, including 214 (67.5%) in the non-LI group, 43 (13.6%) in the single LI group, and 60 (18.9%) in the multiple LI group. The comparison of the three groups showed that older age, male, smoking, drinking, history of previous stroke or transient ischemic attack (TIA), lower levels of high-density lipoprotein cholesterol, larger CMBs and WMHs volume, higher enlarged perivascular spaces (EPVS) grade might be the risk factors for LI. Ordinal multivariable logistic regression analysis showed that male (odds ratio [ OR] 2.058, 95% confidence interval [ CI] 1.084-3.909; P=0.027), previous stroke or TIA history ( OR 1.962, 95% CI 1.089-3.535; P=0.025), larger WMH volume ( OR 8.716, 95% CI 4.034-18.832; P<0.001), higher EPVS grade ( OR 1.915, 95% CI 1.292-2.839; P=0.001), larger DI-CMB volume ( OR 1.022, 95% CI 1.006-1.038; P=0.008) or more DI-CMB number ( OR 1.187, 95% CI 1.005-1.403; P=0.044) were the independent related factors of LI. Multiple linear regression analysis showed that there was a significant correlation between the volume of DI-CMB and the number of LI ( r=0.330, P<0.001). Conclusion:In patients with CSVD, there is a significant correlation between DI-CMBs and LI.
ABSTRACT
Background@#and Purpose The rate of donepezil discontinuation and the underlying reasons for discontinuation in Asian patients with Alzheimer’s disease (AD) are currently unknown. We aimed to determine the treatment discontinuation rates in AD patients who had newly been prescribed donepezil in routine clinical practice in Asia. @*Methods@#This 1-year observational study involved 38 institutions in seven Asian countries, and it evaluated 398 participants aged 50–90 years with a diagnosis of probable AD and on newly prescribed donepezil monotherapy. The primary endpoint was the rate of donepezil discontinuation over 1 year. Secondary endpoints included the reason for discontinuation,treatment duration, changes in cognitive function over the 1-year study period, and compliance as assessed using a clinician rating scale (CRS) and visual analog scale (VAS). @*Results@#Donepezil was discontinued in 83 (20.9%) patients, most commonly due to an adverse event (43.4%). The mean treatment duration was 103.67 days in patients who discontinued. Among patients whose cognitive function was assessed at baseline and 1 year, there were no significant changes in scores on the Mini-Mental State Examination, Montreal Cognitive Assessment, and Trail-Making Test–Black and White scores, whereas the Clinical Dementia Rating score increased significantly (p<0.001). Treatment compliance at 1 year was 96.8% (306/316) on the CRS and 92.6±14.1% (mean±standard deviation) on the VAS. @*Conclusions@#In patients on newly prescribed donepezil, the primary reason for discontinuation was an adverse event. Cognitive assessments revealed no significant worsening at 1 year, indicating that continuous donepezil treatment contributes to the maintenance of cognitive function.
ABSTRACT
BACKGROUND@#Colorectal cancer (CRC) is the second most common cause of cancer-related deaths and has the third highest incidence in the world. Almost half of the patients with CRC have metastases at the time of diagnosis. However, the treatment for patients with metastatic CRC that progresses after approved conventional chemotherapy is still controversial. Chinese medicine (CM) has unique characteristics and advantages in treating metastatic CRC.@*OBJECTIVE@#To assess the effectiveness and safety of CM in patients with metastatic CRC after failure of conventional chemotherapy.@*METHODS@#The study is a multicenter prospective cohort study. A total of 384 patients with documented metastatic CRC after failure of conventional chemotherapy will be included from 9 hospitals among Beijing, Shanghai, Nanjing, and Guizhou, and assigned to three groups according to paitents' wishes: (1) integrated Chinese and Western medicine (ICM) group receiving CM herbal treatment combined with Western medicine (WM) anti-tumor therapy, (2) Chinese medicine (CM) group receiving only CM herbal treatment, and (3) WM group receiving only WM anti-tumor therapy. The primary endpoint is the overall survival (OS). Secondary endpoints include the progression free survival (PFS), quality of life (QOL) assessed by the Functional Assessment of Cancer Therapy-Colorectal (FACT-C) questionnaire, tumor control, and CM symptom score.@*DISCUSSION@#This prospective study will assess the effectiveness and safety of CM in treating metastatic CRC after conventional chemotherapy failure. Patients in the ICM group will be compared with those in the WM group and CM group. If certified to be effective, national provision of CM treatment in metastatic CRC will probably be advised.

ABSTRACT
OBJECTIVE@#To investigate the effects of chidamide combined with anti-myeloma drugs on the proliferation and apoptosis of myeloma cells.@*METHODS@#The proliferation inhibition of the cells was detected by CCK-8 method, and flow cytometry was used to detected the apoptosis of the cells.@*RESULTS@#Chidamide could inhibit the proliferation of myeloma cells and promote the apoptosis of primary myeloma plasma cells in a time- and dose-dependent manner (P<0.05). In NCI-H929 cell line, chidamide combined with low-dose bortezomib and lenalidomide showed synergistic effect, while combined with dexamethasone and pomalidomide showed additive effect. In MM.1s cell line, chidamide combined with bortezomib, dexamethasone, lenalidomide and pomalidomide all showed synergistic effects.@*CONCLUSION@#Chidamide inhibits proliferation of myeloma cells in a time- and dose-dependent manner and promotes apoptosis of primary myeloma plasma cells. Furthermore, it can enhance the inhibitory effect of anti-myeloma drugs.
