ABSTRACT
Objective:To explore the factors leading to communication disorders in ICU patients during mechanical ventilation from the perspective of both patients and medical staff, and to use the theoretical framework of acceptability to identify the barriers that can be improved by intervention.Methods:Using the method of descriptive phenomenology from July to August 2022, 11 patients with mechanical ventilation and 8 medical staff in the comprehensive ICU of a Yuhuangding Hospital in Yantai were selected for interviews by the purpose sampling method, combined with participatory observation. The interviews of patients were conducted off ventilator. With Nvivo12.0 Plus software, the seven-step analysis method of Colaizzi phenomenology was adopted to summarize the theme and the theoretical framework of acceptability was used to identify the obstacle factors that could be improved by intervention.Results:The age of 11 patients was 18-46 years old, the duration of mechanical ventilation was 9.5-312.3 h. The age of 8 medical staff was 26-54 years old, the length of service in ICU was 2-30 years. A total of 14 themes were extracted. For patients: defensive mood, difficulty in presenting information, introverted personality, communication tools are hard to use, emergency treatment conflict, deny the ability to communicate, thought slowness. For medical staff: defensive mood, cognitive load, high time cost, lack of humane communication strategies, poor training, other priorities, loss of confidence in effective communication, awareness of the importance of communication was not enough.Conclusions:There are many factors that can be improved for patients with mechanical ventilation in ICU. It is suggested to speed up the research and development of high-tech and personalized alternative communication tools in China, reduce negative communication between doctors and patients and nurses and patients, and implement evidence-based multi-mode and progressive communication intervention strategies.

ABSTRACT
Objective:To investigate the efficacy and safety of precise mechanical thrombectomy based on ABC 2D scale in acute intracranial large artery occlusion stroke (ALVOs). Methods:A prospective study was performed. Two hundred and two patients with ALVOs accepted early mechanical thrombectomy in Department of Neurology, Maoming Clinical School of Guangdong Medical University from January 2021 to February 2022 were enrolled. They were randomly divided into experimental group ( n=102) and control group ( n=100). Stent retriever partially retracted with intermediate catheter for mechanical thrombectomy (SWIM) was the first choice for patients in control group. ABC 2D scale was used to prejudge the pathogenesis of patients in experimental group: patients with scores of 0-3 were considered as having embolic occlusion and a direct aspiration first pass technique (ADAPT) was the first choice, and SWIM would be chosen if suction catheter could not be in place; patients with scores of 4-7 were considered as having intracranial atherosclerotic stenosis occlusion and SWIM was the first choice. The clinical data, surgical effectiveness, surgical safety, and good prognosis rate 90 d after mechanical thrombectomy (modified Rankin scale scores of 0-2 as good prognosis) of the 2 groups were compared. Results:Experimental group had significantly shorter time from puncture to recanalization (51.0[35.0, 78.5] min vs. 67.0[45.0, 100.0] min), and statistically lower NIHSS scores 24 h after mechanical thrombectomy (10.00[4.75, 16.25] vs. 13.00[8.00, 19.00]), significantly higher good prognosis rate 90 d after mechanical thrombectomy (69.6% vs. 46.0%), statistically lower mortality 90 d after mechanical thrombectomy (3.9% vs. 13.0%) compared with control group ( P<0.05). No significant differences were noted in first-pass effect rate, successful vascular revascularization rate, or incidences of symptomatic intracranial hemorrhage (sICH) and ectopic embolization between the control group and experimental group ( P>0.05). Conclusion:Patients with ALVOs accepted early mechanical thrombectomy can have shorter time from puncture to vascular recanalization and better prognosis after etiologically prejudging by ABC 2D scale for thrombectomy.
ABSTRACT
ObjectiveTo investigate the relationship between e-cigarette use and subjective cognitive decline. MethodsThis study included survey participants aged ≥45 years from the US Behavioral Risk Factor Surveillance System. The prevalence of subjective cognitive decline in people with different tobacco use conditions was estimated. Multivariate logistic regression was employed to determine the relationship between e-cigarette use and subjective cognitive decline， as well as the relationship between co-use of e-cigarette and combustible tobacco and subjective cognitive decline. ResultsA total of 204 032 participants were included in the study. The total prevalence of subjective cognitive decline was 11.46%， whereas among current e-cigarette users， the prevalence was 19.92%. After accounting for confounding factors， current e-cigarette use was identified as a risk factor for subjective cognitive decline compared to individuals who had never used e-cigarettes， with an OR of 1.46 （95%CI： 1.20‒1.77）. Meanwhile， occasional e-cigarette use showed a higher risk， with an OR of 1.54 （95%CI： 1.22‒1.95）. The highest risk was observed with the co-use of e-cigarette and combustible tobacco， with an OR of 1.69 （95%CI： 1.32‒2.16）， followed by current e-cigarette use and former combustible tobacco use， with an OR value of 1.38 （95%CI： 1.08‒1.78）. ConclusionThe use of e-cigarettes increases the risk of subjective cognitive decline， with occasional use demonstrating a more pronounced negative impact. In general， the risk of cognitive decline is greater among e-cigarette users compared to combustible tobacco users. Controlling the use of combustible tobacco， especially e-cigarette， will help reduce the incidence of subjective cognitive decline. Individuals currently using combustible tobacco are advised to explore smoking cessation methods other than transitioning to e-cigarettes.
ABSTRACT
Objective:To investigate the outcome after laparoscopic radical surgery for colorectal cancer in patients over 80 years of age with preoperative combined type 2 diabetes (T2DM).Methods:Clinical data of 919 patients who underwent colorectal cancer laparoscopic resection surgery in Shaanxi Provincial People′s Hospital from January 2015 to January 2019 were retrospectively analyzed. The propensity score matching (PSM) method was used for 1∶1 matching of gender, ASA score, preoperative serum albumin level, body mass index(BMI), preoperative haemoglobin level, clinical tumour pathology TNM staging, tumour location, other medical comorbidities and history of abdominal surgery and finally group of 104 elderly diabetic patients aged ≥80 years with combined T2DM were successfully matched with another 104 non-elderly non-diabetic patients <80 years without combined diabetes group. (1) To compare the differences in operating time, intraoperative bleeding, number of intraoperative blood transfusions, number of lymph nodes dissected, number of ICU treatments, postoperative time to exhaustion and postoperative hospital stay, and postoperative adjuvant chemotherapy between the two groups after matching. (2)To observe the difference in major postoperative complications between the two groups. (3) Patients in both groups were observed for three years post-operative survival rate during the follow-up period. SPSS 25.0 statistical software was used for data analysis. The survival analysis was carried aut by the Kaplan-Meier curve method in parallel and the Log-Rank test.Results:Both groups were balanced in terms of baseline variable after PSM ( P>0.05). There was no difference between the two groups in terms of operative time, intraoperative bleeding, number of intraoperative blood transfusions, number of lymph nodes dissected, or time to postoperative evacuation ( P>0.05). There was a statistically significant difference between two groups in the number of people admitted to the ICU for treatment ( χ2=4.04, P=0.042), and ≥80 years diabetic group was higher. The difference in the incidence of postoperative complications between the two groups was not statistically significant [34.6% (36/104) vs 25.0% (26/104), χ2=2.30, P=0.130]; according to the Clavien-Dindo classification of postoperative complications, the incidence of Clavien-Dindo grade Ⅲ complications in the group ≥80 years with diabetes mellitus were was higher than that in the group <80 years without diabetes [12.5% (13/104) vs 4.8% (5/104), χ2=3.89, P=0.049]. For local surgical complications, the incidence of postoperative anastomotic leak was significantly higher in the ≥80 years diabetic group than in the <80 years non-diabetic group ( χ2=4.70, P=0.030), and the incidence of postoperative wound infection was no statistical significance in the two group. For non-surgical local complications, there was a statistically significant difference in pulmonary infection in the ≥80 years diabetic group compared to the <80 non-diabetic group ( χ2=4.68, P=0.031) and in acute coronary syndrome ( χ2=4.02, P=0.045). Compared with the <80 years non-diabetic group, patients in the ≥80 years diabetic group had significantly longer postoperative hospital stay [(13.3±4.4)d vs (9.2±3.2) d, t=3.41, P=0.019]. The difference in adjuvant chemotherapy after surgery between the two groups was not statistically significant (67.3% vs 76.0%, χ2=1.92, P=0.166). The survival rate at 3 years after surgery was not statistically significant in both groups [68.9% vs 74.2%, χ2=4.34, P=0.085]. Conclusions:The short-term and long-term outcomes of colorectal cancer in advanced age with type 2 diabetes are satisfactory. Adequate preoperative assessment of the patient's physical condition should be carried out, close intraoperative control of blood glucose, and close postoperative monitoring and regulation of blood glucose should be performed, except for patients with severe comorbidities and coexisting diseases that cannot tolerate surgery and advanced tumours that have lost their surgical significance.
ABSTRACT
Objective:To summarize the experience of the precise prevention and control strategy of novel coronavirus infection in the pediatric intensive care unit(PICU)during the epidemic of the Omicron variant.Methods:A retrospective analysis was performed on the strategies and management experience of precise prevention and control of novel coronavirus infection in PICU at Pediatric Hospital of Fudan University from March 1 to May 10, 2022.Results:According to the national and Shanghai novel coronavirus infection prevention and control standards, the PICU in our hospital, in accordance with the specialty characteristics of PICU, cooperated with the hospital′s department of infection and medical department to jointly construct a precise ward management strategy for the outbreak of the omicron mutants infection.Precise prevention and control management strategies were formulated from four aspects: the admission process of critically ill children, the division of PICU ward areas and nosocomial infection protection, the reception management system for children′s family members, and the " bubble management" system for PICU staff, and run them for 3 months.During the epidemic, there was no nosocomial infection of novel coronavirus infection in children or medical staff.During the period, a total of 140 critically ill children were admitted, including 87 cases transferred from the general ward in the hospital, 48 cases from the emergency department(non-febrile, 3 cases transferred by the transfer team), four cases from fever clinic, and one case from control ward.Four of the critically ill children had no emergency nucleic acid test report when they were admitted to the PICU.Among the 140 critically ill children, 54 patients received mechanical ventilation, 18 patients received blood purification, and two patients were monitored after liver transplantation.Seventy-eight (55.7%) children had underlying diseases.Conclusion:During the current round of novel coronavirus epidemic in Shanghai, PICU in our hospital formulated the admission and ward management procedures for critically ill children, which ensured the prevention and control of nosocomial infection of novel coronavirus, and at the same time ensured the treatment of critically ill children to the greatest extent.
ABSTRACT
Objective:To explore the effects of external diaphragm electrical stimulation on the diaphragm thickness and function in mechanically ventilated children.Methods:A randomized controlled trial was conducted in children who were admitted to PICU at Children′s Hospital of Fudan University and received mechanical ventilation between June 2021 and April 2022.The control group was given the routine treatment of mechanical ventilation, and the intervention group was given external diaphragm electrical stimulation in the early stage of mechanical ventilation in addition to routine treatment.Diaphragm thickness was continuously measured by bedside ultrasound every day for one week after mechanical ventilation, and the changing trend of diaphragm thickness was observed, and the diaphragmatic thickening fraction (DTf) and the incidence of ventilator-induced diaphragmtic dysfunction(VIDD) were calculated at the same time.Results:A total of 32 valid samples were included, including 15 cases in intervention group (10 males) and 17 cases in control group (11 males). The median age of the patients was 33 (10, 77) months, and the median duration of mechanical ventilation was 12 (8, 21) days.The reasons for mechanical ventilation in children included respiratory insufficiency in ten cases, brain dysfunction in ten cases, heart failure in eight cases, and postoperative surgery in four cases.The diaphragm end-expiratory thickness (DTe) in intervention group and the control group showed a gradually decreasing trend from the 1st day to the 7th day.The left thickness was reduced by 11% on the 7th day compared to 1st day in intervention group, which was reduced by 18% in control group; the average daily DTe was reduced by 2% per day in intervention group and by 3% per day in control group.The trends on the right and left were similar.The DTe thickness in the intervention group was greater than that in control group, among which, the mean DTe thickness in the left side of the intervention group on the 7th day was (0.110 7±0.023 7)cm, which was greater than that in control group (0.093 5±0.016 9)cm, and the difference was statistically significant ( t=-2.372, P<0.05); On the second day, the mean DTe thickness on the right side in the intervention group was (0.1267±0.0277) cm, which was greater than that in control group (0.104 7±0.018 1)cm, and the difference was statistically significant ( t=-2.688, P<0.05). DTf in the intervention group was lower than that in control group at 7th day, but the difference was not statistically significant(left DTf: adjusted mean difference was -0.117, P=0.088; right DTf: adjusted mean difference was -0.065, P=0.277). The incidence of VIDD in the intervention group was lower than that in control group(33.3% vs.41.2%), but the difference was not statistically significant ( χ2=0.005, P=0.946). Conclusion:External diaphragmatic electrical stimulation may be helpful for alleviating diaphragmatic atrophy in mechanically ventilated children.However, whether the improvement of diaphragm atrophy is beneficial to clinical outcome still needs further study.
ABSTRACT
Objective@#To explore the relationship between anemia and neuropsychological development in various domains among preschool children in China.@*Methods@#Data came from the National Nutrition and Health Systematic Survey for children in China, and 3 261 preschool children aged 2-6 years and their parents from 28 sites across 14 provinces were recruited in this study. Parental and child characteristics were obtained by interview administrated questionnaires. Blood hemoglobin(Hb) concentration was determined by Hemocue method. Neuropsychological development quotients were assessed using the Development Scale for Children Aged 0-6 Years(WS/T 580-2017).@*Results@#The average Hb level was (125.23±11.49)g/L and the overall anemia prevalence was 10.30% among preschool children. After adjusting the confounding factors(sex, age, ethnicity, region, feeding mode, maternal status during pregnancy, etc), developmental quotients of gross motor( β=-2.15, 95%CI =-3.89--0.41), fine motor( β=-2.46, 95%CI =-4.12--0.79), adaptive behavior( β=-2.59, 95%CI =-4.42--0.76), language( β=-3.65, 95%CI =-5.53--1.78), personal social behavior( β=-3.11, 95%CI =-4.94--1.28) and full scale( β=-2.79, 95%CI =-4.10--1.49) among children with anemia were significantly lower than non anemic infants( P <0.05).@*Conclusion@#Anemia was negatively associated with developmental quotient, as well as five domains of gross motor, fine motor, adaptive behavior, language, and personal social behavior in preschool children aged 2-6 years. It is suggested to carry out the work of anemia monitoring and intervention in preschool children to further improve their neuropsychological development.
ABSTRACT
Objective@#To explore relationship between screen time and myopia in children aged 11-14 years in China.@*Methods@#The data were extracted from "National Nutrition and Health Systematic Survey and Application for 0-18 Years Old Children". A total of 12 397 children aged 11-14 years old from 14 provinces and 28 districts/counties in seven regions of China were surveyed by using multi stage stratified random sampling method. Daily screen time and visual acuity information were collected through a questionnaire.@*Results@#The myopia rate of 11-14 years old children in China was 45.0%, among which the rate of girls was higher than that of boys, and the rate of urban was higher than that of rural, and it increased with age ( χ 2=178.82,79.25, 495.96 , P <0.01). The daily screen time median of 12 397 children was 40.0 minutes, with boys(40.0 min) longer than girls( 35.0 min ) and urban children(40 min) longer than rural children(33.0 min) ( χ 2=20.86，102.68， P <0.01). The myopia rate of boys ( 42.5 %) with daily screen time greater than or equal to 60 minutes was higher than that of boys (36.4%) with daily screen time less than 60 minutes, and the myopia rate of girls (55.6%) with daily screen time greater than or equal to 60 minutes was higher than that of girls (48.0%)( χ 2=23.62，34.15， P <0.01). After adjusting for age, gender, region, time of medium and high intensity physical activity, intake of sugary food and sugary beverages, daily sleep time, multivariable Logistic regression model showed that girls with daily screen time greater than or equal to 60 minutes ( OR=1.14, 95%CI =1.03-1.27) had a higher risk of myopia than those with less than 60 minutes. After adjusting for confounding factors, there was no correlation between daily screen time and the degree of myopia in boys or girls( P >0.05).@*Conclusion@#Daily screen time greater than or equal to 60 minutes may be a risk factor for myopia in girls aged 11 to 14 years old. Given the complexity of the factors that affect vision, researches are needed to examine the relationship between screen time and myopia.
ABSTRACT
Objective:To identify the risk factors for postoperative early complications of low rectal cancer treated with intersphincteric resection (ISR).Methods:The perioperative data of 82 patients with low rectal cancer undergoing ISR at the General Surgery Department of Shaanxi Provincial People's Hospital between Jan 2017 to Dec 2021 were retrospectively analyzed. Univariate, Logistic regression and multivariate analysis were used to analyze the risk factors for early complications after ISR, and a nomogram prediction model was drawn. Predictive models are validated.Results:There were 22 patients (27%) with complications. Univariate analysis showed that early complications were related to diabetes (0.021), serum albumin (<0.001), nutritional prognosis index (0.003), neoadjuvant chemoradiotherapy (<0.001), and operation time (<0.001). By multivariate analysis, diabetes ( OR=4.853, 95% CI: 1.059-22.241, P=0.042), low serum albumin ( OR=0.672, 95% CI: 0.468-0.966, P=0.032), neoadjuvant chemoradiotherapy ( OR=4.482, 95% CI: 1.117-17.979, P=0.034) and longer operation time ( OR=1.015, 95% CI: 1.001-1.029, P=0.037) were independent risk factors A nomogram prediction model was thus constructed, and the area under the curve of the nomogram prediction model was 0.888 (95% CI: 0.812-0.965). Conclusion:Diabetes mellitus, low serum albumin, neoadjuvant chemoradiotherapy, and longer operation time are independent risk factors of early postoperative complications for low rectal cancer undergoing ISR.
ABSTRACT
Objective:To investigate the values of Ki-67 expression level and 4 molecular types for risk classification of prognosis in patients with medulloblastoma (MB).Methods:A retrospective study of 92 MB patients who underwent surgery and were confirmed by postoperative pathology in the First Affiliated Hospital of Zhengzhou University from January 2009 to January 2018 was performed. The clinical data and survival data of the patients were collected and sorted out. The overall survival (OS) and progression-free survival (PFS) were analyzed by Kaplan-Meier method, and the log-rank test was performed. Risk stratification of prognosis of patients was performed according to the Ki-67 expression level combined with molecular typing, the low-risk group had Ki-67 positive index ≤50% and WNT or SHH subtype, the medium-risk group had Ki-67 positive index ≤50% and GROUP 3 or GROUP 4 subtype, or Ki-67 positive index >50% and WNT or SHH subtype), and the high-risk group had Ki-67 positive index >50% and GROUP 3 or GROUP 4 subtype. The differences in OS and PFS among different risk groups were compared. A multivariate Cox proportional hazards model was used to assess factors affecting the survival of patients.Results:There were 50 cases (54.3%) with Ki-67 positive index ≤50% and 42 cases (45.7%) with Ki-67 positive index >50%. The 5-year PFS rate and OS rate of patients with Ki-67 positive index ≤50% were 46.9% and 63.1%, and patients with Ki-67 positive index >50% were 28.5% and 32.0%, there were statistical differences in PFS and OS between the two groups ( P values were 0.020 and 0.028). There were 16 cases (17.4%) of WNT subtype, 14 cases (15.2%) of SHH subtype, 40 cases (43.5%) of GROUP 3 subtype and 22 cases (23.9%) of GROUP 4 subtype, their 5-year PFS rates were 78.0%, 76.0%, 19.2% and 19.9%, respectively, and their 5-year OS rates were 82.1%, 76.0%, 40.2% and 0, respectively. MB patients with GROUP 3 or GROUP 4 subtype had poorer PFS and OS than patients with WNT or SHH subtype ( P values were 0.003 and 0.039). Ki-67 expression level and molecular typing were combined to carry out risk classification of prognosis. There were 12 cases (13.0%) in the low-risk group, 56 cases (60.9%) in the medium-risk group, and 24 cases (26.1%) in the high-risk group . There were statistical differences in PFS and OS among MB patients in low-, medium- and high-risk groups (both P < 0.001). Multivariate Cox regression analysis showed that radiotherapy and risk classification of prognosis as medium risk and low risk were independent protective factors for PFS (radiotherapy vs. no radiotherapy: OR = 0.263, 95% CI 0.124-0.556, P < 0.001; medium-risk group vs. high-risk group: OR = 0.069, 95% CI 0.008-0.581, P = 0.014; low-risk group vs. high-risk group: OR = 0.260, 95% CI 0.131-0.514, P < 0.001); radiotherapy and risk classification of prognosis as low risk were independent protective factors for OS (radiotherapy vs. no radiotherapy: OR = 0.221, 95% CI 0.097-0.503, P < 0.001; low-risk group vs. high-risk group: OR = 0.328, 95% CI 0.150-0.717, P = 0.005). Conclusions:The expression level of Ki-67 and 4 molecular types are related to the prognosis of MB patients. The combination of the two can be used to classify the prognosis risk of MB patients, which has reference significance for the prediction of prognosis of patients and the selection of individualized treatment plans.

ABSTRACT
Objective:To probe into the causes, reconstructive strategies, and repair outcomes of asymmetric eyelid configuration after blepharoplasty.Methods:All 73 patients (14 males and 59 females) with asymmetric double eyelid after blepharoplasty were recruited between July 2013 and June 2018 from Department of Plastic and Burns Surgery, West China Hospital, Sichuan University. The patients aged from 18 years to 42 years with the median age of 27 years. The new double eyelid line was designed pre-operation. Releasing subcutaneous adhesion of upper eyelid entirely, trimming inferior orbicularis oculi, adjusting and comparing the attachment position of bilateral levator aponeurosis were performed during surgery. Patients and surgeons marked the appearance of double eyelid both before and after repair operation, results of which were analyzed by t-test.Results:All 73 patients obtained improved double eyelid with primary healing. During follow-up from 8 to 12 months, repaired double eyelid showed satisfactory configuration with smooth natural double eyelid line and symmetric bilateral double eyelid. Of the 73 patients, 3 (4.1%) complaint rough double eyelid line, for whom re-fixation through small incision were adopted and no complication was observed during follow-up time. Scores by patients and surgeons were both significantly better after surgery.Conclusions:Analyzing the causes of asymmetric eyelid after double-eyelid blepharoplasty and repairing it contribute to aesthetic pleasing reconstructed double eyelid.
ABSTRACT
Objective:To explore the value of the model based on multi-sequence magnetic resonance imaging (MRI) radiomics and clinical features in predicting molecular subtypes of pediatric medulloblastoma (MB).Methods:MRI imaging data and clinical data of 100 children with primary MB admitted in the First Affiliated Hospital of Zhengzhou University from January 2011 to January 2020 were analyzed retrospectively.Fifty children with primary MB were allocated to training cohort, and those of the other 50 were allocated to testing cohort by using simple random sampling method.In the training cohort, there were 5 cases of WNT-activated MB (Wingless, WNT), 5 cases of SHH-activated MB (Sonic hedgehog, SHH), 28 cases of non-WNT/non-SHH medulloblastoma Group3 (Group3), 12 cases of non-WNT/non-SHH medulloblastoma Group4 (Group4). The testing cohort included 11 cases of WNT, 3 cases of SHH, 24 cases of Group3 and 12 cases of Group4.The robust and non-redundant features were selected from 5 929 three-dimensional radiomic features extracted from the manually delineated tumor area, and Boruta algorithm was used to further select the optimal features.Based on the selected features, a random forest prediction model was constructed using the training cohort (50 cases), which was further used to evaluate the testing cohort (50 cases). Combined with radiomic features and clinical features, a joint random forest prediction, clinical-radiomic model was constructed.Results:A radiomic model containing 13 optimal radiomics features was used to predict molecular subtypes of MB.The area under curve(AUC) of receiver operating characteristic (ROC) curve for WNT, SHH, Group3 and Group4 MB cases in the testing cohort was 0.923 1, 0.673 7, 0.519 2 and 0.705 0, respectively.Incorporating clinical features into the radiomic model improved AUC for WNT and SHH at 0.944 1 and 0.819 1, respectively.Conclusions:The multi-sequence clinical radiomic model has a high predictive value for pediatric MB with the molecular subtypes of WNT and SHH, which provides decision-making supports for individualized diagnosis and treatment of pediatric MB.
ABSTRACT
Objective:To evaluate the clinical efficacy and safety of oral mifepristone (10 mg/day) versus placebo in the preoperative treatment of uterine fibroids.Methods:This study was a multi-center, randomized, double-blind, placebo, parallel controlled trial. A total of 132 patients with uterine fibroids were randomly divided into study group and control group, with 66 cases in each group. The patients in the study group orally took 1 tablet/day of mifepristone (dose of 10 mg/tablet), the patients in the control group orally took 1 tablet/day of placebo, and both groups were treated for 3 months. The primary efficacy evaluation indicators were the change rate of maximum fibroid volume; the secondary efficacy evaluation indicators included amenorrhea rate, improvement of subjective symptoms and anemia; the safety evaluation indicators included the analysis of adverse events and changes in laboratory biochemical indicators.Results:At the end of treatment, the maximum leiomyoma volume was reduced by 25.97% (95% CI: -34.79%--15.95%) in the study group and reduced by 1.51% (95% CI: -13.03%-11.54%) in the control group. The change rate of the maximum leiomyoma volume before and after treatment in the study group was significantly greater than that in the control group, and the difference in the change rate of the maximum leiomyoma volume between the two groups was -24.84% (95% CI: -36.56%--10.94%), which was much higher than the 10% superiority threshold goal set by this study within the 95% CI interval. At the end of treatment, the complete amenorrhea rate [84% (52/62)], dysmenorrhea elimination rate [98% (61/62)], and menstrual blood loss disappearance rate [87% (54/62)] in the study group were significantly higher than those in the control group (all P<0.05). At the end of treatment, the mean hemoglobin [(131±13) g/L], red blood cell count [(4.5±0.4)×10 12/L] and hematocrit (0.39±0.03) in the study group were significantly increased compared with the baseline, and the differences had statistical significance (all P<0.05); after treatment, the differences in the above three indicators between the two groups had statistical significance (all P<0.01). The serum estradiol level in the study group was significantly lower than that in the control group at the end of treatment, and the difference was statistically significant ( P<0.01). There were no significant differences in follicle-stimulating hormone and cortisol levels before and after treatment between the two groups ( P>0.05). The overall incidences of any adverse event were not significantly different between the two groups (all P>0.05). Abdominal pain was the most common adverse event in the study group [9% (6/65)], but the incidence was not significantly increased compared with the control group [3% (2/64); P>0.05]. Conclusion:Compared with placebo, oral mifepristone 10 mg/day is significantly superior to placebo in reducing the size of uterine fibroids and improving anemia, without significant adverse reactions, and could be used as a drug treatment for patients with of uterine fibroids before surgery.
ABSTRACT
At present, the global prevalence of Helicobacter pylori (Hp) infection is still high. Although bismuth-containing quadruple regimens are recommended by international consensus and guidelines as a first-line treatment for Hp infection, the compliance is decreasing due to more drugs needed and higher adverse events. In recent years, many studies on eradication regimen containing high-dose proton pump inhibitor (PPI) and amoxicillin, a low-resistance and acid-labile antibiotic, demonstrated that the dual therapy could achieve high eradication rate equivalent to the mainstream fist-line therapies and had the advantages of less adverse events, simpler drug composition and higher compliance. However, there are discrepancies in dosage and frequencies of drugs in dual therapies, and cannot reach a unified regimen. This article reviewed all kinds of the dual therapy regimens, which might be helpful for determining the optimal dosage, frequencies, and treatment course, so as to standardize the dual therapy.
ABSTRACT
Objective:To investigate the effect of peripheral blood neutrophil to lymphocyte ratio (NLR) and platelet distribution width (PDW) on the clinical prognosis of childhood medulloblastomaMethods:Clinical data and survival data of 76 pediatric patients who were diagnosed as medulloblastoma by post-operative pathology in the First Affiliated Hospital of Zhengzhou University from January 2009 to December 2016 were collected. Kaplan- Meier method was used to calculate the overall survival(OS) and progression free survival(EFS) rates, Log- rank test was employed to compare the survival rates of different groups, and Cox proportional hazards regression model was used for multivariate analysis. Results:The log- rank test revealed that 5-year PFS rate and OS rate (22.2%, 22.2%) in the high NLR group (NLR>4.94) were significantly lower than those in the low NLR group (NLR≤4.94) (45.6%, 55.7%), and the differences were statistically significant(PFS: P=0.009, OS: P=0.001), and the 5-year PFS and OS (52.3%, 66.5%) of the high PDW group (PDW>15.90) were significantly higher than those in the low PDW group (PDW ≤ 15.90) (27.1%, 32.5%), and the differences were statistically significant(PFS: P=0.032, OS: P=0.039). Univa-riate analysis showed that the extent of resection (PFS: P=0.006, OS: P=0.009), and postoperative radiotherapy (PFS: P=0.011, OS: P=0.001) and postoperative radiotherapy(PFS: P=0.011, OS: P=0.001) were the factors influencing the prognosis of children with medulloblastoma.Multivariate Cox proportional hazards regression model analysis suggested that no postoperative radiotherapy (PFS: P=0.048, OS: P=0.008), NLR>4.94 (PFS: P=0.023, OS: P=0.003) and PDW≤15.90 (PFS: P=0.028, OS: P=0.006) were the independent risk factors for the prognosis of childhood medulloblastoma. Conclusions:Increased NLR and decreased PDW indicate unfavorable prognosis of the childhood medulloblastoma.Therefore, preoperative NLR and PDW may be the potential prognostic markers for childhood medulloblastoma.
ABSTRACT
Objective:To investigate the clinical significance of homeobox gene D3 ( HOXD3) expression in glioma and its biological functions. Methods:A total of 1001 patients with glioma collected from Chinese Glioma Genome Atlas (CGGA) and the Cancer Genome Atlas (TCGA) were chosen in our study; their clinical data and transcriptome data were retrospectively analyzed. One-way analysis of variance was used to evaluate the differences of HOXD3 expressions in different pathological grading of glioma. These patients were divided into HOXD3 low expression group and HOXD3 high expression group according to the average value of HOXD3 expression. Kaplan-Meier survival analysis was used to compare the differences in survival time between patients from the HOXD3 high-expression group and HOXD3 low-expression group. Univariate and multivariate Cox regression analyses were used to investigate the effect of HOXD3 on the prognoses of patients with glioma. Gene ontology (GO) analysis, Kyoto encyclopedia of genes and genomes (KEGG) and gene set enrichment analysis (GSEA) were used to investigate the biological function of HOXD3. Pearson correlation analysis was used to analyze the correlation between HOXD3 expression and expressions of other genes. Results:(1) The expression level of HOXD3 gradually increased with the increase of pathological grading of glioma (in the CGGA data, the expression levels in grading II, III and IV gliomas were 0.737±0.085, 1.323±0.125 and 1.652±0.083, respectively; in TCGA data, the expression levels in grading II, III and IV gliomas were 0.082±0.008, 0.177±0.014 and 0.259±0.016, respectively). The HOXD3 expression levels among different pathological grading of glioma were statistical different ( P<0.05). (2) As compared with that in the HOXD3 low-expression group, the survival time of patients in the HOXD3 high-expression group was significantly shorter ( P<0.05). CGGA data showed that the HOXD3 expression ( HR=1.348, 95%CI: 1.171-1.552, P=0.000), tumor grading ( HR=2.793, 95%CI: 1.981-3.936, P=0.000) and isocitrate dehydrogenase 1 ( IDH1) mutation status ( HR=0.689, 95%CI: 0.492-0.964, P=0.029) were independent influencing factors for prognoses of glioma patients. TCGA data showed that the HOXD3 expression ( HR=2.147, 95%CI: 1.252-3.681, P=0.005), age ( HR=1.036, 95%CI: 1.026-1.046, P=0.000), tumor grading ( HR=3.178, 95%CI: 2.299-4.392, P=0.000) and IDH1 mutation status ( HR=0.440, 95%CI: 0.317-0.613, P=0.000) were independent influencing factors for prognoses of glioma patients. (3) GO, KEGG and GSEA analyses showed that HOXD3 was closely related to the cell cycle; the HOXD3 expression was positively correlated with various cell cycle associated genes ( P<0.05). Conclusion:HOXD3 is an independent influencing factor for prognoses of glioma patients, whose biological function is related to the periodic regulation of glioma.
ABSTRACT
Objective:To investigate the status of Corona Virus Disease 2019 (COVID-19) health literacy and associated factors in Inner Mongolia Autonomous Region.Methods:Based on the multi-stage stratified sampling method, the questionnaire survey of health literacy of COVID-19 were carried out in 55 599 local residents from12 prefecture-level cities of Inner Mongolia Autonomous Region between March 10 and 15, 2020. The questionnaire in details included not only knowledge, attitude and behavior, but also mental health, their scores were calculated using Decimal method. A ≥80% of the correct answer rate of the survey content was regarded as qualified for health literacy. There were 51 722 (93.0%) valid questionnaires, according to the ratio of medical staff to non-medical staff, 32 529 questionnaires were selected for analysis. The health literacy level was defined according to the proportion of qualified people.The credibility and availability of the questionnaires were evaluated by Cronbach′s α coefficient and KMO test. The associated factors were analyzed by Pearson χ 2 test and logistic regression. Results:In Inner Mongolia Autonomous Region, the whole level of health literacy of COVID-19 was 85.7%, and their scores were (26.30±2.48). Knowledge, attitude, and behavioral literacy levels were 61.6%, 95.6%, and 96.8%, respectively. Compared with the population of 15-25 years old, the health literacy level of 46-65 years old was the highest ( OR=2.00, 95% CI: 1.78-2.24). The health literacy level of medical staff group ( OR=2.54, 95% CI: 1.30-4.95) was far higher than the non-medical staff group; the population with college or above education level ( OR=10.22, 95% CI: 9.19-11.36) was significantly higher than the population with education level below college. The degree of anxiety was negatively correlated with education level. Conclusions:The health literacy level of COVID-19 in residents in Inner Mongolia Autonomous Region is relatively high, but the level of knowledge literacy needs to be improved. The main factors affecting the health literacy of COVID-19 among Inner Mongolia residents are age, occupation and education level.
