ABSTRACT
Resumen La cardiomiopatía diabética es una complicación grave de la diabetes causada por estrés oxidativo, inflamación, resistencia a la insulina, fibrosis miocárdica y lipotoxicidad. Se trata de un padecimiento insidioso, complejo y difícil de tratar. El inflamasoma NLRP3 desencadena la maduración y liberación de citoquinas proinflamatorias, participa en procesos fisiopatológicos como la resistencia a la insulina y la fibrosis miocárdica, además de estar estrechamente relacionado con la aparición y progresión de la cardiomiopatía diabética. El desarrollo de inhibidores dirigidos a aspectos específicos de la inflamación sugiere que el inflamasoma NLRP3 puede utilizarse para tratar la cardiomiopatía diabética. Este artículo pretende resumir el mecanismo y las dianas terapéuticas del inflamasoma NLRP3 en la cardiomiopatía diabética, así como aportar nuevas sugerencias para el tratamiento de esta enfermedad.
Abstract Diabetic cardiomyopathy (DCM) is a serious complication of diabetes caused by oxidative stress, inflammation, insulin resistance, myocardial fibrosis, and lipotoxicity; its nature is insidious, complex and difficult to treat. NLRP3 inflammasome triggers the maturation and release of pro-inflammatory cytokines, participates in pathophysiological processes such as insulin resistance and myocardial fibrosis, in addition to being closely related to the development and progression of diabetic cardiomyopathy. The development of inhibitors targeting specific aspects of inflammation suggests that NLRP3 inflammasome can be used to treat diabetic cardiomyopathy. This paper aims to summarize NLRP3 inflammasome mechanism and therapeutic targets in diabetic cardiomyopathy, and to provide new suggestions for the treatment of this disease.
ABSTRACT
Objective: To compare the impact of different prognostic scores in patients with acute-on-chronic liver failure (ACLF) in order to provide treatment guidance for liver transplantation. Methods: The information on inpatients with ACLF admitted at Beijing You'an Hospital Affiliated to Capital Medical University and the First Affiliated Hospital of Zhejiang University School of Medicine from January 2015 to October 2022 was collected retrospectively. ACLF patients were divided into liver transplantation and non-liver transplantation groups, and the two groups prognostic conditions were followed-up. Propensity score matching was carried out between the two groups on the basis of liver disease (non-cirrhosis, compensated cirrhosis, and decompensated cirrhosis), the model for end-stage liver disease incorporating serum sodium (MELD-Na), and ACLF classification as matching factors. The prognostic condition of the two groups after matching was compared. The difference in 1-year survival rate between the two groups was analyzed under different ACLF grades and MELD-Na scores. The independent sample t-test or rank sum test was used for inter-group comparison, and the χ (2) test was used for the comparison of count data between groups. Results: In total, 865 ACLF inpatients were collected over the study period. Of these, 291 had liver transplantation and 574 did not. The overall survival rates at 28, 90, and 360 days were 78%, 66%, and 62%, respectively. There were 270 cases of matched ACLF post-liver transplantation and 270 cases without ACLF, in accordance with a ratio of 1:1. At 28, 90, and 360 days, patients with non-liver transplantation had significantly lower survival rates (68%, 53%, and 49%) than patients with liver transplantation (87%, 87%, and 78%, respectively; P < 0.001). Patients were classified into four groups according to the ACLF classification criteria. Kaplan-Meier survival analysis showed that the survival rates of liver transplantation and non-liver transplantation patients in ACLF grade 0 were 77.2% and 69.4%, respectively, with no statistically significant difference (P = 0.168). The survival rate with an ACLF 1-3 grade was significantly higher in liver transplantation patients than that of non-liver transplantation patients (P < 0.05). Patients with ACLF grades 1, 2, and 3 had higher 1-year survival rates compared to non-liver transplant patients by 50.6%, 43.6%, and 61.7%, respectively. Patients were divided into four groups according to the MELD-Na score. Among the patients with a MELD-Na score of < 25, the 1-year survival rates for liver transplantation and non-liver transplantation were 78.2% and 74.0%, respectively, and the difference was not statistically significant (P = 0.149). However, among patients with MELD-Na scores of 25-30, 30-35, and≥35, the survival rate was significantly higher in liver transplantation than that of non-liver transplantation, and the 1-year survival rate increased by 36.4%, 54.9%, and 62.5%, respectively (P < 0.001). Further analysis of the prognosis of patients with different ACLF grades and MELD-Na scores showed that ACLF grades 0 or 1 and MELD-Na score of < 30 had no statistically significant difference in the 1-year survival rate between liver transplantation and non-liver transplantation (P > 0.05), but in patients with MELD-Na score≥30, the 1-year survival rate of liver transplantation was higher than that of non-liver transplantation patients (P < 0.05). In the ACLF grade 0 and MELD-Na score of≥30 group, the 1-year survival rates of liver transplantation and non-liver transplantation patients were 77.8% and 25.0% respectively (P < 0.05); while in the ACLF grade 1 and MELD-Na score of≥30 group, the 1-year survival rates of liver transplantation and non-liver transplantation patients were 100% and 20.0%, respectively (P < 0.01). Among patients with ACLF grade 2, the 1-year survival rate with MELD-Na score of < 25 in patients with liver transplantation was 73.9% and 61.6%, respectively, and the difference was not statistically significant (P > 0.05); while in the liver transplantation patients group with MELD-Na score of ≥25, the 1-year survival rate was 79.5%, 80.8%, and 75%, respectively, which was significantly higher than that of non-liver transplantation patients (36.6%, 27.6%, 15.0%) (P < 0.001). Among patients with ACLF grade 3, regardless of the MELD-Na score, the 1-year survival rate was significantly higher in liver transplantation patients than that of non-liver transplantation patients (P < 0.01). Additionally, among patients with non-liver transplantation with an ACLF grade 0~1 and a MELD-Na score of < 30 at admission, 99.4% survived 1 year and still had an ACLF grade 0-1 at discharge, while 70% of deaths progressed to ACLF grade 2-3. Conclusion: Both the MELD-Na score and the EASL-CLIF C ACLF classification are capable of guiding liver transplantation; however, no single model possesses a consistent and precise prediction ability. Therefore, the combined application of the two models is necessary for comprehensive and dynamic evaluation, but the clinical application is relatively complex. A simplified prognostic model and a risk assessment model will be required in the future to improve patient prognosis as well as the effectiveness and efficiency of liver transplantation.

Objective@#To understand the prevalence and associated factors of functional constipation(FC) among primary and middle school students in Shaanxi Province, in order to provide a basis for preventing FC in students.@*Methods@#A stratified cluster random sampling method was used to conduct a questionnaire survey on 9 133 primary and middle school students aged 10-18 in eight primary and secondary schools in Shaanxi Province from March to September,2017. Chi square test and multivariate Logistic regression were used to analyze the associated factors of FC among primary and middle school students in Shaanxi Province.@*Results@#There were a total of 364 students meeting the FC Rome IV diagnostic criteria, with a prevalence rate of 3.99%. Among them, there were 155 male students with a prevalence rate of 3.43%, and 209 female students with a prevalence rate of 4.53%. Univariate analysis showed that gender, breastfeeding, separation from parents, long term school meals, types of staple foods, breakfast frequency, cold foods eating frequency, spicy foods eating frequency, fried food eating frequency, pickled food eating frequency, desserts eating frequency, vegetables eating frequency were related to FC, and the differences were statistically significant ( χ 2=7.30,18.75, 20.89,35.54,22.43,16.05,21.31,13.97,10.33,23.96,16.25,17.74, P <0.05). Multivariate Logistic regression analysis showed that female, non breastfeeding, separation from parents, long term school meals, low consumption of staple food/staple food dominated by rice, and never eating vegetables were positively correlated with FC( OR =1.37,1.96,1.52,2.07,1.76,1.58,2.31, P < 0.05 ).@*Conclusions@#The prevalence of functional constipation is higher in primary and middle school students. Attention should be paid to factors related to students dietary habits and food classification to prevent the occurrence of FC in primary and middle school students.
ABSTRACT
Objective@#To explore the association between reading and writing posture with the occurrence of myopia in Chinese children and adolescents, so as to provide a reference for reducing its prevalence among primary and secondary school students.@*Methods@#Using data from the 2020 survey on the current status of hyperopia reserve in primary and secondary school students from six provinces/cities, namely Beijing, Zhejiang, Chongqing, Shaanxi, Liaoning, and Henan selected by multi stage stratified cluster probability sampling method during November 2020 to June 2022. A total 16 782 students who completed the optometry examination of cycloplegia according to the Children and Adolescents Myopia Screening Standard and questionnaire survey were included for analyzing analyze the association between reading and writing posture with myopia.@*Results@#The overall detection rate of myopia among primary and secondary school students was 45.7%, of which 35.0% were primary school students, 84.1% junior high school students, and 90.4% senior high school students. Poor reading and writing posture was found in 73.6% of primary and secondary school students. Adjusting for confounding factors such as gender, school period, region, outdoor time every day, and whether parents were myopic, the results of the multilevel Logistic regression showed that the following factors were positively correlated with myopia:poor reading and writing posture ( OR=1.17, 95%CI =1.07-1.28), never/occasionally reading and writing with a reading distance which was more than one foot away between the eyes and book ( OR=1.28, 95%CI=1.08-1.53, OR=1.23, 95%CI = 1.08- 1.40), teachers occasionally reminding the child of their reading and writing posture ( OR=1.13, 95%CI =1.01-1.25), and often/always reading and writing while lying down or with the face on the arm ( OR=1.15, 95%CI=1.01-1.32, OR=1.46, 95% CI = 1.17-1.82), always reading and writing with the head in the hand ( OR=1.56, 95%CI =1.20-2.01). Further, a negative correlation was detected between myopia and parents occasionally reminding their children of their reading and writing posture ( OR= 0.85 , 95%CI =0.76-0.96) ( P <0.05).@*Conclusion@#Poor reading and writing posture is a risk factor for the development of myopia in primary and secondary school students, and interventions for reading and writing posture need to be strengthened to reduce the occurrence of myopia among primary and secondary school students.
ABSTRACT
Objective@#The study was aimed at exploring the latent classes and factors influencing middle school students health risk behaviors in Beijing, so as to provide a scientific basis for determining key intervention targets and formulating relevant intervention measures.@*Methods@#A questionnaire survey was conducted among 17 730 junior middle school, senior high school and vocational high school students in 16 districts of Beijing from October to December 2022. Six types of health risk behaviors were assessed with latent class analysis, including unhealthy diet, lack of exercise, unintentional harm, intentional harm, substance abuse and Internet addiction behavior.@*Results@#The latent classes of health risk behavior among middle school students in Beijing were divided into three classes:high risk behavior (961 participants, 5.42%), low lack of exercise/high intentional injury (1 099 participants, 6.20%), and low risk behavior (15 670 participants, 88.38%). Disordered multiple Logistic regression analysis indicated that middle school students who were male ( OR =1.45), in high school ( OR =2.00), had other family types ( OR =1.90), possibly had depressed feelings ( OR =2.27), had depressed feelings ( OR =6.18), or were absent from school because of illness in the past year ( OR =1.79) were more likely to be in the high risk than the low risk behavior group. Moreover, middle school students who were male ( OR =2.30), had an extended family ( OR =1.18), had a reorganized family ( OR =1.70), had other family types ( OR =1.94), possibly had depressed feelings ( OR =3.10), had depressed feelings ( OR =4.91), had taken sick leave in the prior 2 weeks ( OR =1.54), or had absence from school because of illness in the past year ( OR =1.71) were relatively more likely to be in the low lack of exercise or high intentional injury group ( P <0.05).@*Conclusion@#Clear latent classes of health risk behaviors among middle school students are found to be present in differing proportions in Beijing. Relevant departments should take targeted intervention measures in a timely manner to reduce the occurrence of health risk behaviors among middle school students.
ABSTRACT
ABSTRACT The prevalence of diabetes mellitus is increasing and is related to sedentary lifestyles and obesity. Many studies were published on the effect of lifestyle interventions on glucose regulation and delay the onset of diabetes in adults with impaired glucose tolerance (IGT) or prediabetes. This study aimed to investigate the role of lifestyle interventions in individuals with IGT or prediabetes using a meta-analytic approach. PubMed, Embase, and the Cochrane Central Register of Controlled Trials databases were searched from their inception up to January 2020 to select eligible randomized controlled trials (RCTs). The weighted mean difference (WMD; for fasting plasma glucose (FPG) and 2-hour plasma glucose (2hPPG)) or relative risk (RR; for the risk of diabetes) with 95% confidence interval (CI) were calculated for pooled effect estimates using the random-effects model. Thirteen RCTs involving 3376 individuals with IGT or prediabetes were selected for this meta-analysis. The results showed that lifestyle interventions were associated with lower FPG (WMD: -0.14; 95% CI: -0.24 to -0.05 mmol/L; p=0.004) and 2hPPG (WMD: -0.66; 95% CI: -1.12 to -0.20 mmol/L; p=0.005) in adults with IGT or prediabetes. Moreover, the risk of diabetes was significantly reduced in individuals who received lifestyle interventions (RR: 0.75; 95% CI: 0.60-0.95; p=0.015). Lifestyle interventions could help improve glucose dysregulation and prevent the progression of diabetes in adults with IGT or prediabetes. Further large-scale RCTs should be conducted to assess the effects of long-term lifestyle interventions on diabetic complications in adults with IGT or prediabetes.

The relationship between middle school and college students depressive symptoms and dietary behaviors was analyzed by conducting a questionnaire.@*Results@#The detection rate of depressive symptoms was 18.2%. The detection rate of depressive symptoms in girls was 19.0%, which was higher than 17.4% in boys( P <0.05), and the differences were of statistical significance( χ 2=8.47, P <0.01). The detection rate of depressive symptoms in city was 17.9%, and in 10 urban areas was 18.5 %( P > 0.05 ), and the differences were of statistical significance( χ 2=1.15, P =0.28). The detection rates of depressive symptoms in vocational high school (21.8%) and high school students(20.6%) were and, higher than that in college students (18.2%) and in junior high school students(15.2%), and the differences were of statistical significance( χ 2=100.38, P <0.01). The rates of students with depressive symptoms drinking sugary drinks(14.4%), eating sweets (22.1%) and eating fried foods every day (12.4%) were higher than that of students without depressive symptoms(7.6%, 12.0%, 5.9%), and the differences were of statistical significance( χ 2=154.62, 215.67, 164.49, P <0.01). The rates of eating fresh fruits(63.3%), vegetables (81.7%) and breakfast every day (53.4%) of the students with depressive symptoms were lower than those without depressive symptoms (72.0%, 88.1%, 74.1%), and the differences were of statistical significance( χ 2=90.77, 90.59, 518.69, P <0.01) Logistic regression analysis showed that the detection rate of depression was the important factor of influencing dietary behaviors( P <0.05).@*Conclusion@#The detection rates of depressive symptoms of vocational high school students and senior high school students in Beijing are higher than those of junior high school students and college students. Depression is closely related to dietary behaviors. Promoting students mental health may help promote students healthy eating.
ABSTRACT
ObjectiveTo investigate the differentially expressed proteins in the plasma exosome of acute-on-chronic liver failure (ACLF) patients with different prognoses, to analyze their functions and biological processes, and to provide a basis for clinical diagnosis. MethodsA prospective study was performed for 10 ACLF patients who were hospitalized and diagnosed in Beijing YouAn Hospital, Capital Medical University, from July 2019 to October 2019, and the patients were followed up for 90 days. The patients who died or received liver transplantation were enrolled as liver transplantation/death group (5 patients), and the patients who survived were enrolled as survival group (5 patients). The Mann-Whitney U test was used for comparison of general data between the two groups. The label-free quantitative proteomic method was used for identification and quantitative analysis of plasma exosome proteins to screen out differentially expressed proteins, and a functional enrichment analysis was performed. R-3.5.1 software was used to perform a hierarchical cluster analysis of differentially expressed proteins to analyze the biological processes involving these proteins. ResultsA total of 860 proteins were identified by the exosome proteomic analysis, and according to the criteria of upregulation ＞1.2 folds or downregulation ＞1.2 folds (P＜0.05), there were 116 differentially expressed proteins. Compared with the liver transplantation/death group, the survival group had 62 upregulated proteins and 54 downregulated proteins. The bioinformatics analysis showed that these differentially expressed proteins mainly participated in immune reaction, signal transduction, vesicle-mediated transport, cell death, and cell proliferation and were closely associated with the signaling pathways including inflammatory response, carbohydrate and amino acid metabolism, hepatocyte injury, and hepatocyte regeneration. ConclusionDifferentially expressed proteins screened out by the label-free quantitative proteomic method can be used as serological markers for the early diagnosis and prognostic evaluation of ACLF.
ABSTRACT
Objective@#To clarify the importance and practical significance of the standardized rate in primary healthcare work by comparing the differences in the prevalence of myopia in districts in Beijing before and after standardization.@*Methods@#This study recruited a total of 41 029 students from 107 primary and secondary schools and 35 kindergartens from the 16 districts of Beijing municipality. All participants underwent distance vision and refractive testing. The presence of myopia was defined as naked eye vision of <5.0 and non-ciliary muscle paralysis under computer optometry with a spherical equivalent objective refractive error of <-0.50 diopters (<-0.50 D). The student composition outlined in the 2018-2019 Beijing Education Development Statistics Summary was used as a standard group to standardize the prevalence of myopia in students from various districts of Beijing. The difference in the pre-and post-standardization rates was used to compare the change in myopia in each district before and after standardization.@*Results@#In 2018, the prevalence of myopia in students from Beijing was 57.3%. Stratified by school period, the prevalence of myopia in preschool, primary school, junior high school, ordinary high school, and vocational high school students was 12.1%, 38.4%, 77.2%, 88.3%, and 73.1%, respectively. Although the prevalence of myopia in Daxing District was the highest both before and after standardization, the difference in the prevalence rate was 13.8 percentage points. The prevalence of myopia in Miyun District was the lowest before standardization. However, after standardization, the prevalence of myopia was lowest in Huairou District.@*Conclusion@#The prevalence of myopia among Beijing students is generally high. Before and after standardization, the prevalence of myopia in different districts was quite different. The results show that, in practice, the standardized prevalence can reveal the true epidemiological characteristics of specific disease.
ABSTRACT
Background: Targetable drug delivery is an important method for the treatment of liver tumors. For the quantitative analysis of drug diffusion, the establishment of a method for information collection and characterization of extracellular space is developed by imaging analysis of magnetic resonance imaging (MRI) sequences. In this paper, we smoothed out interferential part in scanned digital MRI images. Materials and Methods: Making full use of priors of low rank, nonlocal self-similarity, and regularized sparsity-promoting entropy, a block-matching regularized entropy minimization algorithm is proposed. Sparsity-promoting entropy function produces much sparser representation of grouped nonlocal similar blocks of image by solving a nonconvex minimization problem. Moreover, an alternating direction method of multipliers algorithm is proposed to iteratively solve the problem above. Results and Conclusions: Experiments on simulated and real images reveal that the proposed method obtains better image restorations compared with some state-of-the-art methods, where most information is recovered and few artifacts are produced
ABSTRACT
Given their relationship with metabolic syndrome and systematic inflammatory diseases, the pathogenesis of hypertension, hyperglycemia, and hyperlipidemia is closely related. To explore the common genes among these three conditions, spontaneous hypertensive rats (SHR), spontaneous diabetic Goto-Kakizaki rats (GK) and hyperlipidemia rats (HMR) were reared for experiments. Gene array was used to identify the genes of SHR, GK and HMR compared with normal Wistar rats using TBtools software. First, real-time PCR was applied to verify these genes, and Cytoscape software was used to construct networks based on the National Center for Biotechnology Information (NCBI) database. Second, Kyoto Encyclopedia of Genes and Genomes (KEGG) database analysis was performed to classify the genes. Visualization and Integrated Discovery (DAVID) database and Gene Ontology database were used to explore the biological function. Finally, Onto-tools Pathway Express was used to analyze the pathways of shared genes. Importantly, upregulated common genes, such as Bad, Orm1, Arntl and Zbtb7a, were used to construct a network of 150 genes, while downregulated genes, such as Mif and Gpx1, formed a network of 29 genes. Interestingly, the networks were involved in various pathways, such as insulin signal pathway, endometrial cancer pathway, circadian rhythm pathway, and pancreatic cancer pathway. We discovered common genes of SHR, GK and HMR compared with normal Wistar rats, and the association of these genes together with biological function were preliminarily revealed.

Objective: To observe the clinical efficacy of herbal cake-partitioned moxibustion for dysmenorrhea due to deficiency cold. Methods: A total of 70 patients with dysmenorrhea who met the inclusion criteria were randomized into a mild moxibustion group and a herbal cake-partitioned moxibustion group by the random number table, with 35 cases in each group. Shenque (CV 8), Zhongji (CV 3) and bilateral Zigong (EX-CA 1) were selected for both groups. The treatment continued for 3 menstrual cycles. The visual analog scale (VAS) and COX menstrual symptom scale (CMSS) were scored in both groups before treatment, after treatment and at the end of the 3rd menstrual cycle after treatment. The clinical efficacy was evaluated at the end of the 3rd menstrual cycle after treatment. Results: After treatment, the clinical efficacy of the herbal cake-partitioned moxibustion group had the tendency to be superior to that of the mild moxibustion group, while there was no statistically significant difference in the overall efficacy between the two groups (P>0.05). The VAS and CMSS scores after treatment and at the follow-up were significantly lower than those before treatment in both groups (all P<0.05). At the follow-up, the VAS scores in both groups had no significant intra-group differences from those after treatment (both P>0.05). The CMSS scores in both groups were significantly lower than those after treatment (both P<0.05). The VAS scores at the follow-up of both groups had no statistical differences from those after treatment (both P>0.05). After treatment, the CMSS score in the herbal cake-partitioned moxibustion group was significantly lower than that in the mild moxibustion group (P<0.05). At the follow-up, there were no statistical differences in the CMSS score between the two groups (P>0.05). Conclusion: The herbal cake-partitioned moxibustion has the same therapeutic efficacy for dysmenorrhea as the mild moxibustion; the two moxibustion methods can significantly improve the concomitant symptoms of dysmenorrhea, and the herbal cake-partitioned moxibustion is little better.
ABSTRACT
Objective: To observe the clinical efficacy of DZWJY-1 type electronic moxibustion apparatus and traditional moxibustion in treating knee osteoarthritis (KOA). Methods: A total of 76 eligible patients were randomized into an electronic moxibustion apparatus group and a traditional moxibustion group, with 38 cases in each group. The electronic moxibustion apparatus group was intervened by DZWJY-1 type electronic moxibustion apparatus, and the traditional moxibustion group received moxa stick moxibustion for treatment. Neixiyan (EX-LE 4), Dubi (ST 35), Xuehai (SP 10) and Liangqiu (ST 34) were selected for both groups and the treatment was conducted 3 times a week for a total of 12 times. The visual analog scale (VAS) and the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) scores were observed before treatment and after 6 and 12 sessions of treatment, respectively. Results: There were 4 dropout cases in the traditional moxibustion group. Therefore, this trial had 72 valid cases, including 38 cases in the electronic moxibustion apparatus group and 34 cases in the traditional moxibustion group, the differences in the baseline data between the two groups were statistically insignificant (P>0.05). After 6 and 12 sessions of treatment, the VAS scores decreased significantly with the increase of treatment sessions in both groups (all P<0.01), and the betweengroup differences were statistically insignificant at the same time points (both P>0.05). The pain intensity was evaluated using the weighted value of VAS score. The markedly effective rate was 47.4％ and the total effective rate was 89.5％ in the electronic moxibustion apparatus group, versus 50.0％ and 94.1％ in the traditional moxibustion group, and the betweengroup differences were statistically insignificant (both P>0.05). After 6 and 12 sessions of treatment, the total score and the component scores including pain, stiffness and difficulty moving in the WOMAC decreased significantly with the increase of treatment sessions in both groups (all P<0.01), and the between-group differences were statistically insignificant (all P>0.05). Conclusion: Electronic moxibustion apparatus and traditional moxibustion both are effective in reducing joint pain and improving joint function in KOA patients, and they are equivalent comparing the clinical efficacy.
ABSTRACT
BACKGROUND: Light exposure is a common stress factor in in vitro manipulation of embryos in the reproductive center. Many studies have shown the deleterious effects of high-intensity light exposure in different animal embryos. However, no transcriptomic studies have explored the light-induced injury and response in preimplantation embryos. RESULTS: Here, we adopt different time-courses and illumination intensities to treat mouse embryos at the 2-cell stage and evaluate their effects on blastulation. Meanwhile, single-cell transcriptomes from the 2-cell to blastocyst stage were analyzed after high-intensity light exposure. These data show that cells at each embryonic stage can be categorized into different light conditions. Further analyses of differentially expressed genes and GO terms revealed the light-induced injury as well as the potential repair response after high-intensity lighting. Maternal-to-zygote transition is also affected by the failure to remove maternal RNAs and deactivate zygotic genome expression. CONCLUSION: Our work revealed an integrated response to high-intensity lighting, involving morphological changes, long-lasting injury effects, and intracellular damage repair mechanisms.

All departments should take active and effective measures to control the newly onset and progression of low vision and improve eyesight.
ABSTRACT
Terbutaline aerosol and budesonide suspension are commonly used in the treatment of bronchial asthma, and budesonide suspension has local high efficiency and anti-inflammatory effects. In this paper, we selected 240 patients with bronchial asthma and randomly divided them into two groups. The experimental group was treated with atomization inhalation of terbutaline, after 5 minutes interval, nebulized inhalation of budesonide was performed. The control group was treated with atomized inhalation of mixed liquid as terbutaline and budesonide. After treatment, the cough scores of the two groups decreased, and the dyspnea score improved significantly compared with that before treatment P<0.05]. After treatment, the levels of IL-6, BNP and CRP were decreased in the two groups. There was a significant difference between the two groups after treatment [P<0.05]. The incidence of adverse drug reactions was low. There were 2 cases of panic disorder and 8 cases of pharyngeal discomfort in the experimental group. The results show that the interval medication of terbutaline and budesonide in the treatment of bronchial asthma can achieve better clinical efficacy and can provide reference for clinical treatment. In addition, this method can effectively reduce the level of inflammatory factors in acute asthma patients, thereby reducing the damage of inflammatory factors to the body

Objective:To observe the clinical effect of lower-reinforcing and upper-reducing acupuncture method for hyperplasia of mammary gland (HMG) and its influence on estradiol (E2) and progesterone (P).Methods:A randomized,single-blinded and controlled trial was conducted.A total of 124 cases conforming to the inclusion criteria were randomized by random number table into a treatment group and a control group,with 62 cases in each group.Patients in both groups received acupuncture therapy at the same acupoints,while patients in the treatment group received lower-reinforcing and upper-reducing method,and patients in the control group received even reinforcing-reducing manipulation.The treatment started around 10 d before menstruation and was conducted every other day.Patients received 5 treatments in each menstruation cycle for consecutive 3 cycles.The levels of E2,P and E2/P and clinical efficacy were measured before and after treatment.Results:After treatment,the breast lump size,pain intensity and concomitant symptoms score in both groups were substantially lower than those before treatment,showing statistical significances (all P＜0.01),and the improvement in the treatment group was higher than that in the control group,and the between-group comparisons showed statistical significances (all P＜0.01).After treatment,the overall effective rate was 91.9％ in the treatment group,higher than 72.6％ in the control group,and the between-group comparison showed a statistical significance (P＜0.01).After treatment,levels of E2,P and E2/P value showed no statistical significance when compared with those before treatment in the two groups (all P＞0.05).Conclusion:Lower-reinforcing and upper-reducing acupuncture method can effectively alleviate clinical symptoms and signs in HMG patients,and produce a better effect than even reinforcing-reducing manipulation.The majority of HMG patients' E2,P level and E2/P value were not beyond the normal ranges;therefore,acupuncture showed no substantial influence on E2 and P levels and E2/P value.
ABSTRACT
Objective To evaluate the clinical efficacy of electronic mild moxibustion equipment in treating knee osteoarthritis (KOA) by using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Method Sixty-six eligible patients were randomized into a mild moxibustion equipment group of 33 cases and a moxibustion group of 33 cases. The mild moxibustion equipment group was intervened by electronic mild moxibustion equipment, and the moxibustion group was treated with moxibustion. In the two groups, same acupoints were selected, including Neixiyan (EX-LE4), Dubi (ST35), Xuehai (SP10) and Liangqiu (ST34), and the treatment lasted for 4 weeks. The WOMAC scores of the two groups were observed before and after the treatment.Result The WOMAC scores dropped significantly in both groups after the intervention (P<0.001), and the score of the mild moxibustion equipment group was significantly lower than that of the moxibustion group (P<0.05).Conclusion Electronic mild moxibustion equipment and moxibustion both can effectively mitigate joint pain and improve knee joint function, but the moxibustion equipment can produce a more significant effect in improving the joint function than moxibustion.
ABSTRACT
The systematic treatment based on gemcitabine plus cisplatin is recommended as the current standard chemotherapy for unresectable or metastatic biliary tract cancers.However,the exact benefits from the recognized regime are still dismal.We thus elicit this study in an attempt to analyze whether targeted therapy coupled with various chemotherapy could produce improvement of survival benefits.The clinical trials were searched electronically from databases till July 2016 published in English and Chinese.Nine hundred and sixty-four patients from 7 trials were identified in our analysis.The overall analysis achieved a significantly higher overall response rate (ORR) among the patients treated with targeted drugs plus chemotherapy than chemotherapy alone (OR=1.87;95％ CI:1.37-2.57;P=0.000),but failed in the overall progression-free survival (PFS) [mean difference (MD)=0.63;95％ CI:-0.45-1.72;P=0.26] and overall survival (OS) (MD=-0.67;95％ CI:-2.54-1.20;P=0.49).In the sub analysis,better ORR was obtained with the addition of EGFR (OR=1.75;95％ CI:1.20-2.56;P=0.004) and VEGFR (OR=2.5;95％ CI:1.28-4.87;P=0.007) targeted therapy.Furthermore,the sub analysis of EGFR target showed an significant improvement on PFS (MD=l.36;95％ CI:0.29-2.43;P=0.01).No significant differences were observed in the incidences ofneutropenia (OR=1.37;95％ CI:0.89-2.12),thrombocytopenia (OR=l.40;95％ CI:0.83-2.39),anemia (OR=l.21;95％ CI:0.62-2.38),peripheral neuropathy (OR=1.52;95％ CI:0.81-2.88),increased AST/ALT (OR=l.40;95％ CI:0.82-2.39) as well as fatigue (OR=1.65;95％ CI:0.96-2.84) in either of the treatment groups.In conclusion,better ORR associated with chemotherapy combined with targeted therapy (both targeting EGFR and VEGF) is found in the present mcta-analysis without the cost of increased unacceptable toxicities,but regretfully not for the OS.The sub-analysis of targeting EGFR instead of VEGF obtains a superior PFS.Otherwise,there is no statistically significant difference in the overall PFS between the combination regime and chemotherapy alone.Given the paucity of favorable data,we need further studies to characterize optimal targeted agents to confirm the potential value to biliary tract cancer.
