ABSTRACT

α7 nicotinic acetylcholine receptor(α7nAChR)is widely expressed in the central nervous system and immune system,and plays a neuro-immunoregulatory role.On the one hand,α7nAChR is involved in the transmission of neurotransmitters,the conduction of excitatory signals and the maintenance of synaptic plasticity,which is of great significance for maintaining the normal and stable neurocognitive function.On the other hand,as an important part of the cholinergic anti-inflammatory pathway,α7nAChR is involved in the regulation of physiological and pathological processes such as inflammatory response,oxidative stress,apoptosis and autophagy in the central system,and plays an immunomodulatory and neuroprotective role,thus being potential target for improving perioperative neurocognitive function.This article reviews the biological characteristics of α7nAChR and its effect on perioperative neurocognitive function,in order to provide ideas and methods for clinical improvement of perioperative neurocognitive function in surgical patients.

ABSTRACT

Background The occurrences of occupational stress and sleep disorders are closely related. As a high-risk group of occupational stress, the sleep quality of locomotive engineers is of great significance for road traffic safety. Objective To explore the direction and degree of occupational stress affecting the sleep quality among locomotive engineers, and to analyze potential mediating and moderating roles of response strategy and overcommitment in the relationship. Methods From July 1st to July 31st, 2022, a total of 6219 locomotive engineers from three locomotive depots of China Railway Lanzhou Group Corporation were selected. We conducted an online survey on occupational stress, overcommitment, response strategy and sleep quality using the Effort-Reward Imbalance, Personal Resources Questionnaire, and Pittsburgh Sleep Quality Index. Single factor analysis and correlation analysis were conducted using SPSS 25.0 software, mediation and moderation models were constructed using the Process V3.3 macro program plugin, and Harman's single factor test was used for common method bias testing. Results A total of 6219 questionnaires were distributed, and 5738 valid questionnaires were collected, with an effective response rate of 92.27%. The average locomotive engineers' occupational stress score (1.22±0.29), overcommitment score (16.38±3.55), response strategy score (50.00±10.00), and sleep quality score (11.51±3.95) were calculated. The Pearson correlation analysis results showed that occupational stress was positively correlated with overcommitment and sleep quality (r=0.435, 0.321, P<0.01), and negatively correlated with response strategy (r=−0.286, P<0.01); overcommitment was positively correlated with sleep quality (r=0.367, P<0.01), and negatively correlated with response strategy (r=−0.210, P<0.01); there was a negative correlation between response strategy and sleep quality (r=−0.244, P<0.01). Occupational stress positively associated with sleep quality in locomotive engineers (b=3.658, t=21.177, P<0.001); response strategy exhibited a partial mediating role between occupational stress and sleep quality, with an effect size of 0.581, accounting for 15.88% of the total effect; overcommitment presented a significant moderating effect in the first half of the mediating process of "occupational stress-response strategy-sleep quality" (P<0.001). Conclusion Occupational stress has an impact on the sleep quality of locomotive engineers through the mediating effect of response strategy, and the first half of this mediating pathway is moderated by overcommitment.

ABSTRACT

Objective: To understand the vaccination status of enterovirus type 71 (EV71) inactivated vaccines in China from 2017 to 2021 and provide evidence for making policy on immunization strategy against hand, foot and mouth disease (HFMD). Methods: Using the reported dose number of EV71 vaccination and birth cohort population data collected by the China immunizaiton program information system to estimate the cumulative coverage of EV71 vaccine by the end of 2021 among the birth cohorts since 2012 at national, provincial, and prefecture levels, and analyze the correlation between the vaccination coverage and the potential influencing factors. Results: As of 2021, the estimated cumulative vaccination coverage of the EV71 vaccine was 24.96% in birth cohorts since 2012. The cumulative vaccination coverage was between 3.09% and 56.59% in different provinces, between 0 and 88.17% in different prefectures. There was a statistically significant correlation between vaccination coverage in different regions and the region's previous HFMD prevalence and disposable income per capita. Conclusions: Since 2017, the EV71 vaccines have been widely used nationwide, but the coverage of EV71 vaccination varies greatly among regions. Vaccination coverage is higher in relatively developed regions, and the intensity of previous epidemic of HFMD may have a certain impact on the acceptance of the vaccine and the pattern of immunization service. The impact of EV71 vaccination on the epidemic of HFMD requires further studies.

The measurement data with normal distribution is expressed by xˉ± s, the comparison between the two groups adopts independent sample t-test, the comparison between multiple groups adopts one-way ANOVA, and the comparison between two groups adopts LSD method and Bonferroni correction; The measurement data of non-normal distribution is expressed by M( Q1, Q3), and the comparison between the two groups is conducted by Mann-Whitney U test. Pearson method and Spearman mothod were used for correlation analysis. Logistic regression model was used to analyze the influencing factors of children with Kawasaki disease complicated with CAL. The diagnostic value of serum sCD40L level in Kawasaki disease complicated with CAL was analyzed by drawing the ROC curve. Results:All 127 children with Kawasaki disease were divided into CAL group (45 cases) and non-CAL group (82 cases) according to the presence or absence of CAL. The serum level of sCD40L in CAL group was higher than that in non-CAL group, healthy control group and fever control group ((7.03±0.91) μg/L vs (4.66±1.23), (1.73±0.96), (2.21±1.08) μg/L), the difference was statistically significant (all P<0.001). The serum level of sCD40L in children with coronary artery dilation in CAL group was lower than that in children with small CAA, medium CAA and large CAA ((6.04±0.22) μg/L vs (6.95±0.69), (8.02±0.57), (8.23±0.26) μg/L), the difference was statistically significant (all P<0.001). Serum sCD40L level and platelet count (PLT), C-reactive protein (CRP), N-terminal pro brain natriuretic peptide (NT-proBNP), interleukin-6 (IL-6), IL-8 and tumor necrosis factor (TNF-α) in children with Kawasaki disease All were positively correlated ( r=0.31, P<0.001, r=0.32, P<0.001, r=0.26, P=0.003, r=0.58, P<0.001, r=0.27, P=0.002, r=0.39, P<0.001).

ABSTRACT

Objective: To investigate the association between the distribution of tumor infiltrating lymphocytes (TIL) in EBV associated lymphoepitheliomatoid carcinoma (LELC) and the pathological subtypes of LELC, as well as the clinical significance of TIL distribution. Methods: The LELC patients with sufficient tumor tissues, complete clinical data and positive EBER, who visited Zhejiang Cancer Hospital, Hangzhou, China from January 2006 to October 2018, were selected. Various immunohistochemical markers (CD20, CD138, CD4, CD8, CD56 and FOXP3) were examined for TIL typing. Two pathologists reviewed the hematoxylin and eosin (HE) staining sections and interpreted the immunohistochemical results. Correlation analysis was used to evaluate the relationship between the distribution of TIL subgroups and LELC's pathological characteristics. Survival analyses were conducted to study the prognostic values of TIL subgrouping. Results: A total of 102 patients with EBV related LELC were included. 46 of them were classic LELC (c-LELC) with rich interstitial TIL, and 56 were non-classic LELC (n-LELC) with relatively fewer interstitial TIL. The results of TIL analysis showed that all subtypes of c-LELC were rich in TIL, with B lymphocytes as the dominant subgroup. The number of TIL in n-LELC was fewer than that in c-LELC, with T lymphocytes as the dominant subgroup. There was no significant difference in the distribution of plasma cells between the two groups. Survival analysis showed that the total number of TIL, and the infiltrations of CD20+B cells, CD4+T cells, and FOXP3+Treg cells were associated with better overall survivals (P=0.004, 0.003, 0.008 and 0.025, respectively) and disease-free survivals (P=0.011, 0.003, 0.038 and 0.041, respectively) in patients with LELC. Conclusions: The morphologic subtypes of EBV-related LELC have different tumor immune characteristics. The total number of TIL in the stroma of c-LELC is significantly higher than that of n-LELC. Interestingly, B lymphocytes are the dominant TIL in c-LELC, while T lymphocytes are the dominant TIL in n-LELC. The infiltration of TIL, CD20+B cells, CD4+T cells and FOXP3+Treg cells in LELC may suggest a better prognosis.

ABSTRACT

Objective:To evaluate the accuracy of bedside lung ultrasound in predicting postoperative pulmonary complications (PPCs) in the patients undergoing radical resection of gastrointestinal cancer.Methods:One hundred and eight patients of both sexes, aged >18 yr, undergoing elective radical resection of gastrointestinal cancer with general anesthesia, were enrolled in the study. Lung ultrasound was performed before surgery (T 1) and at 2, 4 and 7 days after surgery (T 2-4). Lung ultrasound score (LUS) and B-line score were recorded. Serum procalcitonin (PCT) concentrations and blood routine were recorded, and systemic immune-inflammatory index (SII) was calculated. All the patients underwent chest CT examination before surgery and 7 days after surgery. The results of chest CT and clinical diagnosis were used as the gold standard for PPCs. The occurrence of PPCs within 7 days after surgery was recorded. The patients were divided into PPCs group and non-PPCs group according to the development of PPCs. Spearman′s correlation analysis was used to analyze the correlation of B-line score and LUS with PPCs, PCT and SII. The receiver operating curve was used to evaluate the accuracy of B-line score and LUB in predicting PPCs. Results:One hundred and three patients were finally enrolled in the study, including 45 patients in PPCs group and 58 patients in non-PPCs group, and the incidence of PPCs was 43.7%. Both B-line score and LUS were positively correlated with PPCs at T 1 ( P<0.001), and B-line score and LUS were positively correlated with PCT and SII at T 2-4 ( P<0.001). The AUC (95% confidence interval) of B-line score and LUB in predicting PPCs were 0.926 (0.879-0.972) and 0.909 (0.852-0.965), respectively ( P<0.001), the best cut-off values of B-line score and LUB in predicting PPCs were set at 25.5 and 11.5 respectively, and the sensitivity and specificity of B-line score were 0.80 and 0.88 respectively, and the sensitivity and specificity of LUB were 0.78 and 0.93 respectively. Conclusions:Bedside pulmonary ultrasonography (B-line score and LUS) can accurately predict the occurrence of PPCs in the patients undergoing radical resection of gastrointestinal cancer and dynamically evaluate the condition of PPCs, and B-line score >25.5 and LUS score >11.5 indicate a high risk of PPCs.

ABSTRACT

Objective:To evaluate the accuracy of ultrasound measurement of airway parameters in predicting difficult mask ventilation (DMV).Methods:Ninety-six patients, aged 18-90 yr, with body mass index of 16-39 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, undergoing elective endotracheal intubation under general anesthesia, were included in this study. Clinical airway evaluation was performed at 1 day before surgery, and modified Mallampati classification, thyromental distance and rating of the upper lip bite test were recorded. At 30 min before anesthesia induction, mandibular condylar motion, tongue longitudinal cross-sectional area and transverse diameter of tongue were measured by ultrasound, and the tongue volume (product of tongue longitudinal cross-sectional area and transverse diameter of tongue) was calculated. Mask ventilation was performed after induction of anesthesia, mask ventilation difficulty grade ≥Ⅲ was defined as DMV, the patients were divided into 2 groups according to whether DMV occurred: non-DMV group (NDMV group) and DMV group. Correlations between the clinical airway evaluation indexes and ultrasonic airway parameters with statistically significant differences between groups and DMV were assessed using Spearman′s rank correlation. The area under the receiver operating characteristics curve was used to evaluate the accuracy of each parameter in predicting DMV, the critical value was determined, and the accuracy, sensitivity, specificity, positive and negative predictive values were calculated. Results:The modified Mallampati classification, rating of the upper lip bite test, ultrasonic tongue longitudinal cross-sectional area, transverse diameter of tongue and tongue volume were positively correlated with DMV, and thyromental distance and mandibular condylar motion were negatively correlated with DMV ( P<0.05). The area under the receiver operating characteristics curve of mandibular condylar motion and tongue volume in predicting DMV were 0.898 and 0.862, respectively, the cut-off values were 1.19 cm and 99.94 cm 3, respectively, and the sensitivity and specificity were all over 70% and 90%, respectively, the positive predictive values were 92.31% and 88.46%, respectively. Conclusions:Ultrasonic measurements of mandibular condylar motion and tongue volume can accurately predict DMV.

ABSTRACT

OBJECTIVE@#To observe the effects of Tiaoshen (regulating the spirit) acupuncture on cognitive function and sleep quality in patients with primary insomnia (PI).@*METHODS@#Sixty patients with PI were randomly divided into an observation group (30 cases, 2 cases dropped off) and a control group (30 cases, 2 cases dropped off, 1 case was excluded). The patients in the observation group were treated with acupuncture at Baihui (GV 20), Shenting (GV 24), Sishencong (EX-HN 1), and bilateral Benshen (GB 13), Shenmen (HT 7), Neiguan (PC 6), Sanyinjiao (SP 6). The patients in the control group were treated with shallow needling at non-effective points. Each treatment was provided for 30 min, once every other day, 3 treatments per week for 4 weeks. The Montreal cognitive assessment (MoCA), digit span test (DST), trail making test (TMT)-A, Pittsburgh sleep quality index (PSQI), and fatigue scale-14 (FS-14) were used to assess cognitive function and sleep quality before and after treatment, as well as in follow-up of 4-week after treatment completion. Correlation analysis was conducted between the differences in PSQI scores and differences in MoCA scores before and after treatment in the observation group.@*RESULTS@#Compared with before treatment, the total score, visuospatial and executive function score and delayed memory score of MoCA as well as DST backward score were increased (P<0.01), while TMT-A time, PSQI and FS-14 scores were significantly reduced (P<0.01) after treatment and in follow-up in the observation group. Compared with before treatment, the PSQI score in the control group was reduced (P<0.01, P<0.05). After treatment and in follow-up, the observation group had significantly higher total score, visuospatial and executive function score, delayed memory score of MoCA, and DST backward score compared to the control group (P<0.05, P<0.01). In the observation group, the TMT-A time was significantly shorter than that in the control group (P<0.05, P<0.01), and the PSQI and FS-14 scores were significantly lower than those in the control group (P<0.01). In the observation group, there was a negative correlation between the difference in PSQI scores (post-treatment minus pre-treatment) and the difference in MoCA scores (post-treatment minus pre-treatment) (r=-0.481, P<0.01). A similar negative correlation was found between the difference in PSQI scores (follow-up minus pre-treatment) and the difference in MoCA scores (follow-up minus pre-treatment) (r=-0.282, P<0.05).@*CONCLUSION@#Tiaoshen acupuncture could improve cognitive function, enhance sleep quality, and alleviate daytime fatigue in patients with PI. The improvement in cognitive function in patients with PI is correlated with the improvement in sleep quality.

ABSTRACT

OBJECTIVES@#To study the left heart structure and functional characteristics of term neonates with intrauterine growth restriction (IUGR).@*METHODS@#This study included 86 term neonates with IUGR admitted to the Neonatal Ward of Beijing Friendship Hospital, Capital Medical University from January 2019 to January 2022 as the IUGR group, as well as randomly selected 86 term neonates without IUGR born during the same period as the non-IUGR group. The clinical data and echocardiographic data were compared between the two groups.@*RESULTS@#The analysis of left heart structure and function showed that compared with the non-IUGR group, the IUGR group had significantly lower left ventricular mass, left ventricular end-diastolic diameter, left ventricular end-systolic diameter, left atrial diameter, end-diastolic interventricular septal thickness, left ventricular posterior wall thickness, left ventricular end-diastolic volume, left ventricular end-systolic volume, and stroke volume (P<0.05) and significantly higher ratio of end-diastolic interventricular septal thickness to left ventricular posterior wall thickness, proportion of neonates with a mitral peak E/A ratio of ≥1, and cardiac index (P<0.05). The Spearman correlation analysis suggested that stroke volume was positively correlated with birth weight and body surface area (rs=0.241 and 0.241 respectively; P<0.05) and that the ratio of end-diastolic interventricular septal thickness to left ventricular posterior wall thickness was negatively correlated with birth weight and body surface area (rs=-0.229 and -0.225 respectively; P<0.05).@*CONCLUSIONS@#The left ventricular systolic function of neonates with IUGR is not significantly different from that of neonates without IUGR. However, the ventricular septum is thicker in neonates with IUGR. This change is negatively correlated with birth weight and body surface area. The left ventricular diastolic function may be impaired in neonates with IUGR.

ABSTRACT

OBJECTIVES@#To study the genetic characteristics, clinical characteristics, and prognosis of children with primary dilated cardiomyopathy (DCM).@*METHODS@#A retrospective analysis was performed on the medical data of 44 children who were diagnosed with DCM in Hebei Children's Hospital from July 2018 to February 2023. According to the genetic testing results, they were divided into two groups: gene mutation-positive group (n=17) and gene mutation-negative group (n=27). The two groups were compared in terms of clinical data at initial diagnosis and follow-up data.@*RESULTS@#Among the 44 children with DCM, there were 21 boys (48%) and 23 girls (52%). Respiratory symptoms including cough and shortness of breath were the most common symptom at initial diagnosis (34%, 15/44). The detection rate of gene mutations was 39% (17/44). There were no significant differences between the two groups in clinical characteristics, proportion of children with cardiac function grade Ⅲ or Ⅳ, brain natriuretic peptide levels, left ventricular ejection fraction, and left ventricular fractional shortening at initial diagnosis (P>0.05). The median follow-up time was 23 months, and 9 children (20%) died, including 8 children from the gene mutation-positive group, among whom 3 had TTN gene mutation, 2 had LMNA gene mutation, 2 had TAZ gene mutation, and 1 had ATAD3A gene mutation. The gene mutation-positive group had a significantly higher mortality rate than the gene mutation-negative group (P<0.05).@*CONCLUSIONS@#There is no correlation between the severity of DCM at initial diagnosis and gene mutations in children. However, children with gene mutations may have a poorer prognosis.

ABSTRACT

Objective@#To evaluate the impact of bleomycin/etoposide/cisplatin (BEP) and paclitaxel/carboplatin (PC) chemotherapy regimens on the fertility and prognostic outcomes in malignant ovarian germ cell tumor (MOGCT) patients who underwent fertility-sparing surgery (FSS). @*Methods@#A propensity score matching algorithm was performed between the BEP and PC groups. The χ2 test and the Kaplan-Meier method were used to compare the fertility outcome, disease-free survival (DFS) and overall survival (OS). The Cox proportional hazards regression analysis was used to identify risk factor of DFS. @*Results@#We included 213 patients, 185 (86.9%) underwent BEP chemotherapy, and 28 (13.1%) underwent PC chemotherapy. The median age was 22 years (range, 8–44 years), and the median follow-up period was 63 months (range, 2–191 months). Fifty-one (29.3%) patients had a pregnancy plan, and 35 (85.4%) delivered successfully. In the before and after propensity score matching cohorts, there were no significant differences in spontaneous abortion, selective termination of pregnancy, during-pregnancy status, and live birth between the BEP and PC groups (p>0.05). Fourteen (6.6%) patients experienced recurrence, including 11 (5.9%) in the BEP group and 3 (10.7%) in the PC group. Four (1.9%) patients in the BEP group died. Kaplan-Meier analysis revealed no significant differences in DFS (p=0.328) and OS (p=0.446) between the BEP and PC groups, and the same survival results were observed in the after matching cohort. @*Conclusion@#The PC regimen is as safe as the BEP regimen for MOGCT patients with fertility preservation treatment, and no differences were observed in fertility and clinical prognosis.

ABSTRACT

Objective: To explore the vaccination coverage of the 13-valent pneumococcal conjugate vaccine (PCV13) in China from 2017 to 2021. Methods: Using the reported number of PCV13 administrated doses from 2017 to 2021 and the population data from 31 provinces in China, which were collected by the Immunization Program Information System and summarized data at different levels (prefecture, provincial, and national). Collecting batch release data of PCV13 during the same period through the official website of the National Institutes for Food and Drug Control. The average coverage level of PCV13 was calculated by comparing the number of PCV13 vaccinations reported annually to the number of births in that year, and the spatial auto-correlation analysis was conducted in 2021 at the prefecture level. The coverage of PCV13 vaccination was estimated by the total vaccine doses administered each year divided by the number of newborn in the year, as of the administrated dose number per 100 people. Results: From March 2017 to December 2020, the total batch release of PCV13 was 20.06 million, with a total of 71.54, 384.75, 475.45, and 10.8886 million doses each year. During the same period, PCV13 reported doses were 20.2369 million and the vaccination doses from 2017 to 2021 were 4.08, 170.46, 407.52, 599.77, and 8.4185 million doses, respectively. From 2017 to 2021, the ratio of PCV13 doses administrated per 100 infants in each year was 0.25, 10.26, 23.81, 38.16, and 69.90 doses per 100 people, respectively. The range of the ratio in each province increased from 3.85 doses in 2017 to 264.41 doses per 100 people in 2021. The spatial auto-correlation analysis results showed that based on prefecture-level cities, there was spatial clustering in a certain area of PCV13 coverage from 2017 to 2021, and the spatial correlation in 2021 was the highest. The hotspot analysis showed that the hotspot areas with high coverage levels of PCV13 were concentrated in Jiangsu, Zhejiang, Shanghai, Fujian and their surrounding areas. The cold spots with low vaccine coverage were concentrated in Yunnan, Qinghai, Tibet, and their surrounding areas. Conclusion: The average coverage level of PCV13 is low in China with significant regional differences.

The range of the ratio in each province increased from 3.85 doses in 2017 to 264.41 doses per 100 people in 2021. The spatial auto-correlation analysis results showed that based on prefecture-level cities, there was spatial clustering in a certain area of PCV13 coverage from 2017 to 2021, and the spatial correlation in 2021 was the highest. The hotspot analysis showed that the hotspot areas with high coverage levels of PCV13 were concentrated in Jiangsu, Zhejiang, Shanghai, Fujian and their surrounding areas. The cold spots with low vaccine coverage were concentrated in Yunnan, Qinghai, Tibet, and their surrounding areas. Conclusion: The average coverage level of PCV13 is low in China with significant regional differences.

ABSTRACT

Objective:To develop a multimodal MRI-based radiomics model for the differential diagnosis of benign and malignant lung lesions, and to compare the discriminative abilities of different models.Methods:Totally 114 patients with 115 lesions (44 benign and 71 malignant) in Nantong First Peoples′s Hospital from January 2014 to October 2019 were included in the study. All patients underwent non-enhanced MR examination, and textural features from T 1WI,T 2WI and apparent diffusion coefficient (ADC) imaging were extracted. The feature selection methods included L1 based, mutual information, tree based, recursive feature elimination and F-test. Then we constructed a prediction model by using logistic regression (LR), support vector machine (SVM), random forest (RF) and k-nearest neighbor (KNN) respectively. In order to control the number of modeling features and reduce the ininterpretability of the model, the new model was obtained by manually modifying some parameters of the hyperparameter model. One hundred and fourteen cases were rotated as training and validation sets. The performance of each model was evaluated by confounding matrix and receiver operating characteristic (ROC) curve. Results:The area under the curve (AUC) of T 2WI based LR model for the differential diagnosis of benign and malignant pulmonary nodules/masses was 0.71 and the F1 score was 0.57. Based on T 1WI images, LR and SVM model could be used to identify benign and malignant pulmonary nodules, the AUC before parameter adjustment were 0.77 and 0.78, the accuracy after parameter adjustment (LR a,SVM a) was 0.67, 0.70, and both the AUC were 0.72. However, no matter which feature or classifier was selected, both the AUC and accuracy of ADC-based model were less than 0.70. Conclusion:Multimodal MRI-based radiomics model is valuable for the differential diagnosis of benign and malignant pulmonary nodules/masses, and T 1WI-based model shows the best discrimination.

ABSTRACT

Objective: To explore the relationship between daily tea intake and cardiovascular disease (CVD) mortality. Methods: PubMed, EMbase, The Cochrane, Chinese Biomedical Literature Database, CNKI, and Wanfang Database were searched to collect research on tea intake and CVD mortality. The search period was from the establishment of the database to June 2020. Two researchers independently screened and extracted literature. The risk of bias was evaluated in the included studies, a dose-response meta-analysis was conducted, sensitivity analysis and publication bias analysis of the research results, and quality evaluation of the included literature and GRADE classification of the evidence body were performed. Results: A total of 21 cohort or case-control studies were included, including 1 304 978 subjects. Among them, 38 222 deaths from CVD were reported. The quality scores of the included studies were all ≥ 6 points. The dose-response meta-analysis showed that for every additional cup of tea intake per day, the mortality rate of CVD decreased by about 3% (95%CI 0.95-0.98, P<0.05), and there was a non-linear dose-response relationship (P<0.05). Compared with people who do not drink tea, people who drink 1 to 8 cups of tea a day have 8% lower CVD mortality (RR=0.92, 95%CI 0.89-0.95), 13% (RR=0.87, 95 %CI 0.84-0.91), 15% (RR=0.85, 95%CI 0.82-0.89), 15% (RR=0.85, 95%CI 0.81-0.89), 16% (RR=0.84, 95%CI 0.80-0.89), 16% (RR=0.84, 95%CI 0.81-0.88), 16% (RR=0.84, 95%CI 0.81-0.87), 16% (RR=0.84, 95%CI 0.80-0.88), respectively. The results of traditional meta-analysis showed that compared with people who do not drink tea, people who drink more than 1 cup of tea a day are associated with 14% lower CVD mortality rate (RR=0.86, 95%CI 0.81-0.91, I2=73.2%, P<0.05). The results of subgroup analysis showed that compared with the corresponding people who did not drink tea, men who drank more than 1 cup of tea a day reduced the CVD mortality rate by 24%, women by 14%, European and American populations by 12%, and Asian populations by 15%. The population who consumed green tea decreased CVD mortality by 15%, and the population of non-smokers decreased CVD mortality by 20% (all P<0.05). The population who consumed black tea decreased CVD mortality by 8%, and the smoking population who consumed black tea decreased CVD mortality by 3%, and the difference was not statistically significant (all P>0.05). The results of the bias analysis showed that Begg=0.42 and Egger=0.62, indicating that the distribution on both sides of the funnel chart is symmetrical, suggesting that there is no publication bias. The results of sensitivity analysis showed that the effect size of the outcome index did not change significantly after excluding any article, indicating that the results are robust and credible. The GRADE evaluation showed that the evidence grades of the outcome indicators were all low grade. Conclusions: Daily tea consumption is related to reduced CVD mortality. It is therefore recommended to drink an appropriate amount of tea daily.

ABSTRACT

Objective: To analyze the impact of cancer on the recurrence rate of atrial fibrillation (AF) after AF radiofrequency ablation and further evaluate the feasibility of radiofrequency ablation therapy in cancer patients with AF. Methods: This study was a single-center, retrospective study. Cancer patients with AF undergoing radiofrequency ablation for the first time in the First Affiliated Hospital of Dalian Medical University from May 30, 2008 to September 30, 2018 were included (cancer group). AF patients without cancer undergoing radiofrequency ablation for the first time during the same period served as non-cancer group. Clinical data including age, gender, past history, cancer and AF-related parameters, etc. were analyzed. Patients were followed up after radiofrequency ablation. The primary endpoints were AF recurrence or all-cause death. Kaplan-Meier survival analysis was used to analyze the effect of cancers on the recurrence after AF ablation. The multivariate cox regression analysis was further applied to correct for other confounding factors to analyze whether the impact of cancers on the recurrence of atrial fibrillation was statistically significant. Results: A total of 90 patients were enrolled, there were 30 patients in the cancer group (mean age (64.8±6.6) years, 16 (53.3%) males) and 60 patients in the non-cancer group (mean age (63.6±6.2) years, 32 (53.3%) males). Clinical data, such as age, gender, and cancer treatment, were similar between the two groups. During an average follow-up period of (328.7±110.2) days, there were 6 AF recurrences (recurrence rate 20.0%) in the cancer group, and 17 AF recurrences (recurrence rate 28.3%) in the control group. AF recurrence rate was similar between the two groups (P>0.05). During the follow-up period, there was no all-cause death in the two groups. Kaplan-Meier survival analysis showed that cancer was not related to AF recurrence after radiofrequency ablation (P = 0.383). After adjusting for other confounding factors, the multivariate Cox regression analysis showed that cancer was not an independent predictor of AF recurrence after radiofrequency ablation (HR=0.508, 95%CI: 0.192-1.342, P = 0.172). Conclusions: The combination of cancer has no impact on the recurrence of AF after radiofrequency ablation. For cancer patients with AF, radiofrequency ablation therapy can be considered as a feasible heart rhythm control treatment strategy.

ABSTRACT

Objective:To investigate the effect of attention and interpretation therapy on sleep dysfunction and quality of life in perimenopausal syndrome patients.Methods:From August 2018 to January 2020, a total of 76 patients with perimenopausal syndrome were divided into experimental group (38 cases) and control group (38 cases) according to the random number table method. Two groups recieved routine therapy and nursing care, on the basis of this, the experimental group was given attention and interpretation therapy for 10 weeks. Before intervention and after 10 weeks of intervention, the effects were assessed by Pittsburgh Sleep Quality Index (PSQI) and Menopause-Specific Quality of Life (MENQOL), respectively.Results:There was no significant difference in the score of PSQI, MENQOL before intervention between the two groups ( P>0.05). After intervention, the sleep quality, sleep duration, sleep efficiency scores and total PSQI scores were 0.79±0.10, 1.48±0.23, 1.11±0.22, 9.70±0.59; in addition, the vasomotor symptoms, psychological symptoms, somatic symptoms and total MENQOL scores were 3.06±0.81, 2.06±0.81, 2.50±0.51, 2.63±0.39 in the experimental group, significanlty lower than those in the control group (1.03±0.22, 1.85±0.33, 1.25±0.28, 10.59±0.66, 3.69±0.95, 2.83±0.77, 2.92±0.94, 3.18±0.53), the differences were statistically significant ( t values were 2.306-6.021, P<0.05). Conclusions:Attention and interpretation therapy can effectively alliviate sleep dysfunction and improve quality of life of perimenopausal syndrome patients.

ABSTRACT

OBJECTIVE:To study influential factors for medication compliance of phosphate binder in patients with maintenance hemodialysis and the effects of pharmacist intervention ,and to improve medication compliance and the effects of disease control. METHODS :The patients with maintenance hemodialysis who were treated in the blood purification center of our hospital from Jun. to Dec. ,2019 were selected for questionnaire survey. The questionnaires involved general information , medication compliance of phosphate binder ,disease and medicine related knowledge ,social support ,self-efficacy. The t-test,χ2 test and multivariate Logistic regression analysis were used to analyze influential factors for medication compliance. The patients were randomly divided into pharmaceutical intervention group and non-intervention group. Intervention group were provided with pharmaceutical care for 3 months according to risk factors. Blood phosphorus level and medication compliance was compared between 2 groups. RESULTS :Totally 298 patients completed the survey (effective recovery rate of 96.1%). Among them ,163 patients(54.7%)had good adherence to phosphate binder ,while 135 patients(45.3%)had poor compliance. Results of single factor analysis showed that medication compliance of phosphate binder was closely associated with age ,dialysis duration , parathyroid hormone levels ,total daily dose ,daily dose of phosphate binder ,disease and medicine related knowledge scores , social support ,self-efficacy(P<0.05). Results of multivariate Logistic regression analysis showed that total daily dose ,daily dose of phosphate binder ,disease and medicine related knowledge scores ,social support and self-efficacy were the influential factors for medication compliance (P<0.05 or P<0.01). Medication compliance ,disease control status ,disease and medicine related knowledge score , social support and self-efficacy in pharmaceutical intervention group were significant improved , blood phosphorus level was significant lower ,compared with non-intervention group (P<0.05). CONCLUSIONS :Independent risk factors influencing medication compliance of phosphate binder include total daily dose ,daily dose of phosphate binder ,disease and medicine related knowledge scores ,social support and self-efficacy. The patients with maintenance hemodialysis have poor compliance to phosphate binder. Pharmacists should take individualized and targeted intervention measures for the above risk factors,which can effectively improve the medication compliance and disease prognosis of patients.
