ABSTRACT

BACKGROUND@#Previous studies have suggested that screen time (ST) has a negative effect on children's emotional and behavioral health, but there are few longitudinal studies that have been conducted with infants and toddlers. This study sought to examine the effect of ST in early childhood on emotional and behavioral problems in children aged 4 years, based on a birth cohort study in China.@*METHODS@#A total of 2492 children aged 4 years were enrolled in this study. The parents and guardians of each child completed a questionnaire that included items eliciting information on children's birth information, socio-demographic information at baseline, and ST at each follow-up. Emotional and behavioral problems were assessed using the Strengths and Difficulties Questionnaire (SDQ) at 4 years of age. Multivariate logistic analysis was used to explore the effects of ST on emotional and behavioral problems.@*RESULTS@#The percentages of children with ST > 0 h/day at age 0.5 years, ST > 2 h/day at age 2.5 years, and ST > 2 h/day at age 4 years were 45.7, 55.5, and 34.5% respectively. The prevalence of emotional and behavioral problems was 10.8%. ST at 6 months was a risk factor for emotional symptoms and hyperactivity at the age of 4 years. ST at age 2.5 years was a risk factor for hyperactivity at the age of 4 years. However, ST at age 4 years was a risk factor for total difficulties, conduct problems, peer problems, hyperactivity, and prosocial behavior.@*CONCLUSIONS@#Higher ST exposure at early childhood is associated with later emotional and behavioral problems. In particular, sustained high ST exposure is a risk factor for behavioral problems. These findings suggested the importance of controlling ST to prevent the occurrence of emotional and behavioral problems in the early years.

ABSTRACT

In ancient times, there were two types of "Juhong" came from the tangerines(Citrus reticulata) and the pomelos(C. grandis and its cultivars), which corresponded to Juhong and Huajuhong recorded in the Chinese Pharmacopoeia respectively. In different periods, Juhong basically came from the same species and the same medicinal parts, but there were also some differences. This article sorted out the ancient and modern literature, under the guidance of "Succession theory of Medicinal materials varieties" and "Change theory of Medicinal materials varieties"(XIE Zong-wan), and combined with field investigation, the evolution and reasons of the original plants and medicinal parts of Juhong were analyzed. In the Han Dynasty and before, the peel of tangerines and pomelos were both used as medicine. In the Southern and Northern Dynasties, the way tangerine peel was used was dried and aged, and then "soaked in hot water and scraped off the mesocarp", which had the essence of only using exocarp as medicine of Juhong already, and its original plant was C. reticalata. In the Song Dynasty, the name of "Juhong" and its medicinal usage were recorded in book on materia medica, and the species and medicinal parts of tangerine were inherited from the previous dynasties. The way tangerine peel was used was only dried and aged without removing the mesocarp. The medicinal material obtained by the way was called Chenpi(dried and aged tangerine peel). The item "Juhong" listing as a separate medicinal material was first recorded in the Collected Discussions from Materia Medica(Bencao Huiyan) in the Ming Dynasty. In the Ming Dynasty, the Dao-di habitat of Juhong was recorded as Guangdong province in most books on materia medica, and the original plants probably were C. reticalata and C. grandis 'Tomentosa'(Huazhou pomelo, a special cultivated species of C. grandis produced in Huazhou, Guangdong, which was recorded in the Chinese Pharmacopoeia as "Huajuhong"), according to the records in the local chronicles. During the Qing Dynasty and the Republic of China, the original plants of Juhong were C. reticalata and C. grandis 'Tomentosa'. Of the two, the latter one was considered as the better. As far the medicinal part, it was still the exocarp, while the whole young fruit of C. grandis 'Tomentosa' began to be used as medicine. After the founding of The People's Republic of China, the exocarps of Citrus reticalata, C. grandis and C. grandis 'Tomentosa' were listed in the Chinese Pharmacopoeia under "Juhong". From the Northern and Southern Dynasties to the Republic of China, C. grandis exocarp was a fake of Juhong. Therefore, it was contradictory to historical records that C. grandis exocarp was listed in the Chinese Pharmacopoeia as Huajuhong. Juhong had been divided into two types as "Juhong" and "Huajuhong" since 1985. The medicinal part of Huajuhong was only the exocarp of immature and nearly mature fruits, but not the whole young fruit, the actual mainstream medicinal part of Huajuhong. The results are helpful to clarify the historical evolution of species and medicinal parts of Juhong and Huajuhong. It is suggested that in the next edition of Chinese Pharmacopoeia, only C. grandis 'Tomentosa' should be included as the original plant of Huajuhong, and C. grandis should be deleted, and the young fruit should be added in the medicinal parts besides the exocarp of immature and nearly mature fruit.

ABSTRACT

Point-of-care testing (POCT) is a new field in the development of laboratory medicine. It is an immediate test needed for carrying out medical measures in the medical field. As the long term anticoagulant treatment of patients expands, the use of fibrinolytic and antiplatelet drugs, and the need for rapid screening of thromboembolic and hemorrhagic diseases increases, the immediate and rapid test of blood coagulation has been widely used. A large number of studies have showed that the bedside coagulation meters are fast, simple, they can provide more reliable and accurate screening data, and greatly reduce the turnaround time(TAT). POCT coagulation testing is especially suitable for anticoagulation and thrombolytic therapy bedside monitoring.

ABSTRACT

Objective:To investigate the developmental behavior of early term infants at 6 months and its difference from that of complete full-term infants.Methods:A healthy maternal and infant birth cohort in maanshan city, established in Maanshan Maternal and Child Health Hospital from June 2015 to June 2016. Birth outcomes were copied from the hospital electronic medical record system after delivery. The Chinese Ages and Stages Questionnaires was used to assess developmental behavior. The chi-square test and multivariate unconditional logistic regression model were used to analyze the differences in the behavioral development of early and full term infants.Results:The birth rate of early term infants was 24.74% (500/2 021). The detection rates of communication, gross motor, fine motor, problem solving and individual-social areas in early term infants were 2.1%, 3.2%, 6.1%, 6.3% and 2.7%, respectively. The detection rate of problem-solving area in early term infants was significantly higher than that in the full-term infants (6.3% vs. 3.7%, χ 2=5.42, P<0.05). After controlling for confounding factors, compared with full-term infants, the risk of problem-solving area in early infants was significantly increased ( OR=1.65, 95%CI:1.01-2.70, P<0.05). Conclusion:The risk of behavioral retardation in Early term infants is significantly higher than that in full-term infants, and long-term follow-up and appropriate early development promotion interventions are needed to improve their quality of life.

ABSTRACT

The incidence of adenocarcinoma of esophagogastric junction (AEG) is increasing worldwide annually. Surgical resection still plays the most important role in multi-modality therapy for AEG. However, due to the specialities of tumor location and biological features, general surgeons and thoracic surgeons do not reach an agreement on regional lymph-adenectomy, extents of resection, surgical approaches, etc. The development of minimally invasive surgery makes it possible to operate by laparoscopy and thoracoscopy. With the promotion of neoadjuvant therapy, a multidisciplinary team will be essential for optimal diagnosis and treatment in the near future. From the developmental perspective of a general surgeon, the authors summarize current status and controversies of the diagnosis and treatment of AEG, and inspect its research advances.

ABSTRACT

Objective:To investigate the effect of exosomes (Exo) secreted by brain vascular endothelial cell bEnd.3 after ischemic preconditioning (IPC) on neurons suffering from oxygen and glucose deprivation (OGD).Methods:bEnd.3 was exposed to OGD for 3 h to simulate IPC in vivo. After 48 h of reoxygenation, the Exo (IPC Exo) in the conditioned medium were extracted and identified by Western blot and transmission electron microscopy. IPC Exo were incubated with primary cultured mouse cortical neurons for 24 h. Confocal microscope was used to observe whether Exo could be uptaked by primary cultured mouse cerebral cortical neurons. The primary cultured cortical neurons were divided into control group, OGD group, OGD+ IPC Exo (5 μg/ml, 10 μg/ml, 20 μg/ml) groups and sham OGD group (treated with Exo secreted by bEnd.3 cultured under normoxia conditions). The cell viability was detected by CCK-8 and cell survival/death detection kit.Results:Transmission electron microscopy showed that the extract of bend.3 culture medium showed typical morphology of Exo, i. e., a double concave disc-shaped vesicle with a diameter of 30-100 nm. Western blot analysis showed that the extract of bEnd.3 medium highly expressed Exo markers Alix and Tsg101. Confocal microscopy showed that Exo could be uptaked by primary cultured mouse cortical neurons, and the uptake of Exo was widely distributed in the cytoplasm and synapses. Compared with the OGD group, the addition of 10 and 20 μg/ml IPC Exo could significantly increased the neuronal viability ( P<0.05), while the addition of sham Exo had no neuroprotective effect. Conclusion:Exo released by cerebral vascular endothelial cells after IPC have protective effect on neurons suffering from OGD.

ABSTRACT

Type 1 diabetes (T1D) results from dysfunction of pancreatic islets β cells. Recent studies supported that endoplasmic reticulum (ER) stress takes an important role in pancreatic β cell excessive loss, resulting in T1D. Here, we aimed to review the relationship between ER stress and T1D. Additionally, we also reviewed the potential mechanisms underlying ER stress mediated T1D. Studies have shown that severe ER stress is directly involved in the pancreatic β cells destruction and pathogenesis of T1D. ER stress plays a key part in pancreatic β cells and T1D, which will help in developing new effective therapeutics for T1D.

ABSTRACT

BACKGROUND@#Traditional Chinese exercises (TCEs) have a positive effect on glycemic control and hemoglobin A1c (HbA1c), but there is no consensus on the benefits of TCEs for patients with prediabetes.@*OBJECTIVE@#The objective of this study was to systematically investigate the effects of TCEs on blood glucose control in patients with prediabetes.@*SEARCH STRATEGY@#Comprehensive retrieval of randomized controlled trials (RCTs) was carried out using PubMed, Cochrane Library, Embase, China National Knowledge Infrastructure, VIP Database for Chinese Technical Periodicals, Wanfang Data Knowledge Service Platform, China Biology Medicine disc, Google Scholar and Baidu academic databases. The retrieval window ranged from the establishment of the database to December 2018, and references related to the included trials were searched without language restrictions.@*INCLUSION CRITERIA@#The study included RCTs with a clinical diagnosis of prediabetes that was also treated with TCEs.@*DATA EXTRACTION AND ANALYSIS@#Literature screening, data extraction and literature quality assessment were performed independently by two researchers. In the case of disagreement, a third party was invited to negotiate and make a decision. Standardized mean difference (SMD) was used to estimate the therapeutic effect. Meta-analysis was performed using Review Manager 5.3.5 and Stata 15.0. Heterogeneity was assessed using Q test and I, and the source of heterogeneity was determined using Galbraith diagram and sensitivity analysis. A Q test resulting in P  50% indicated significant difference and random effect model analysis was performed. Otherwise, a fixed effect model was applied. Begg's and Egger's tests were used to assess publication bias.@*RESULTS@#Nine RCTs involving 485 participants were included in this study. The results showed that TCEs could reduce fasting blood glucose (FBG), 2 h blood glucose (2hPBG) and HbA1c in patients with prediabetes. The treatment subgroup showed that an intervention of 6 months had better results, while the Gongfa subgroup showed that the TCE Baduanjin yielded better results. (1) FBG: SMD = -0.73, 95% confidence interval (CI) [-0.97, -0.50], P < 0.00001; Baduanjin: SMD = -0.83, 95% CI [-1.13, -0.53], P < 0.00001; 6 month treatment: SMD = -0.73, 95% CI [-1.20, -0.26], P = 0.002. (2) 2hPBG: SMD = -0.75, 95% CI [-0.94, -0.57], P < 0.00001; Baduanjin: SMD = -0.62, 95% CI [-0.91, -0.32], P < 0.00001; 6 month treatment: SMD = -0.91, 95% CI [-1.39, -0.44], P = 0.0002. (3) HbA1c: SMD = -0.56, 95% CI [-0.89, -0.23], P = 0.00008; Baduanjin: SMD = -0.46, 95% CI [-0.83, -0.08], P = 0.02; 6 month treatment: SMD = -0.77, 95% CI [-1.24, -0.29], P = 0.002.@*CONCLUSION@#TCEs had positive effects in improving blood glucose levels in patients with prediabetes. Hence, TCEs may be of potential therapeutic value for patients with prediabetes, as an adjuvant therapy along with other treatments. Although the evidence suggests that the intervention is effective for 6 months, the mechanism of TCEs on glycemic control, the minimum exercise dose and their safety remain to be further studied.

ABSTRACT

Citri Sarcodactylis Fructus is a both medicinal and edible species specified by the China Ministry of Health, with a long history in China. According to the ancient monographs about materia medica, it was found that the records of the Citri Sarcodactylis Fructus on the original plants were confused. This paper reviewed the ancient monographs about materia medica, and made a summarization and textual research on the name, origin, habitat, processing methods, medicinal properties and clinicacy efficacy of Citri Sarcodactylis Fructus based the comprehensive analysis on modern literatures and authoritative books of Chinese herbal medicine. The results indicated that there were many bynames of Citri Sarcodactylis Fructus. Before the Yuan Dynasty, there was a mixed use of Citri Sarcodactylis Fructus and Citri Fructus, which were not distinguished from each other in terms of nature and taste until the Yuan dynasty. Citri Sarcodactylis Fructus was a varietas of Citri Fructus. The main shape of the original plant of Citri Sarcodactylis Fructus is "like a human hand with fingers" as recorded in ancient monographs about materia medica. The main places of origin of Citri Sarcodactylis Fructus were Guangdong, Zhejiang, Fujian, Sichuan, which were relatively stable. There were fewer records about medicinal proces-sing methods of Citri Sarcodactylis Fructus. Only steaming and baking methods were found in ancient monographs about materia medica, and the steaming method could reduce the irritability of Citri Sarcodactylis Fructus. The processing of therapeutic dietary of Citri Sarcodactylis Fructus was widely used in folk, which was represented by Chaozhou Laoxianghuang, a traditional succade made of Citri Sarcodactylis Fructus. According to the 2015 edition of Chinese Pharmacopoeia, Citri Sarcodactylis Fructus had effects in soothing liver and regulating gas, relieving pain in the stomach, eliminating dampness and resolving phlegm, which was basically consistent with the descriptions in ancient monographs about materia medica. This paper defined the original plant of Citri Sarcodactylis Fructus, and sorted out and summarized the processing methods, nature and taste of Citri Sarcodactylis Fructus, so as to provide data support for the standardization of the processing technology and the development and utilization of Citri Sarcodactylis Fructus.

ABSTRACT

Coronavirus disease 2019 (COVID-19) has spread rapidly around the world. In order to diagnose COVID-19 more quickly, in this paper, a depthwise separable DenseNet was proposed. The paper constructed a deep learning model with 2 905 chest X-ray images as experimental dataset. In order to enhance the contrast, the contrast limited adaptive histogram equalization (CLAHE) algorithm was used to preprocess the X-ray image before network training, then the images were put into the training network and the parameters of the network were adjusted to the optimal. Meanwhile, Leaky ReLU was selected as the activation function. VGG16, ResNet18, ResNet34, DenseNet121 and SDenseNet models were used to compare with the model proposed in this paper. Compared with ResNet34, the proposed classification model of pneumonia had improved 2.0%, 2.3% and 1.5% in accuracy, sensitivity and specificity respectively. Compared with the SDenseNet network without depthwise separable convolution, number of parameters of the proposed model was reduced by 43.9%, but the classification effect did not decrease. It can be found that the proposed DWSDenseNet has a good classification effect on the COVID-19 chest X-ray images dataset. Under the condition of ensuring the accuracy as much as possible, the depthwise separable convolution can effectively reduce number of parameters of the model.

ABSTRACT

Colla Corii Asini(Ejiao)is an important Chinese medicine used in China for thousands of years, and is well known for its famous tonic properties. The herbalogical study was detailed carried out based on the naming, habitat, harvesting, processing, medicinal properties and clinical efficacy. The results showed that the name of Ejiao could be traced back to Shennong's Materia Medica, and various names of Lvpi Jiao, Penfu Jiao and Fuzhi Jiao were recorded in other ancient books. In the many intervening centuries, the main materials of Ejiao had been replaced from cow leather before Tang Dynasty to donkey skin in the middle to late Tang Dynasty. This phenomenon could be probably caused by complicated social factors of various periods and different efficacy of Ejiao made by all kinds of raw materials. Ejiao was merely processed with the simple methods before Tang Dynasty, which subsequently improved avariety of methods to enhance the supplementation action. Most importantly, Ejiao has a wide clinic application along with the development of processing theories and methods, which can be found in various Classics, especially in imperial medical case record in Qing Dynasty.

ABSTRACT

Coicis Semen is widely used as a raw material which can be used as both medicine and food among people. According to the ancient monographs on materia medica and relevant documents on the processing specifications in various provinces and cities, herba logical study on the historical evolution of the processing methods of Coicis Semen was conducted in this paper from the aspects of collecting and processing methods of Coicis Semen, the processing methods in the past dynasties and the nature, flavour and efficacy of Coicis Semen. The results showed that the processing methods of Coicis Semen recorded in monographs on materia medica mainly included stir-frying, glutinous rice stir-frying, salt processing(including salt cooking and salt stir-frying), stir-frying with the earth scraped from the wall facing east, and ginger juice stir-frying, etc. Among them, stir-frying, and stir-frying with the earth scraped from the wall facing east are still used nowadays. The bran stir-frying is the improved version of glutinous rice stir-frying in order to be adaptive to the modern-day situation and the needs of the present. In addition, the ancient shell removal and kernel keeping method are also included in the processing procedures in modern local processing specifications, which are combined with frying to form a new method named "Fazhi" processing( "Fazhi" means a processing method of multiple procedures). The 2015 edition of Chinese Pharmacopoeia records that Coicis Semen is helpful to clear dampness and promote diuresis, strengthen the spleen and prevent diarrhea, eliminate impediment, discharge pus, resolve toxin and a mass, etc., which are consistent with those contained in ancient monographs on materia medica. After the "Fazhi" processing, the cold nature of Coicis Semen has been removed and its nature,flavour and meridian tropism have been changed, so its application scopes expanded. The results of this study clearly traced the history of the collecting and proces-sing of Coicis Semen, summarized the nature, flavour and efficacy of Coicis Semen contained in both ancient and modern literature, and provided a historical basis for the standardization of the subsequent processing technology of Coicis Semen, the clinical application of various processed products, and the further development and utilization of medicinal materials.

ABSTRACT

Lipopolysaccharide (LPS)-induced inflammation causes massive threatening diseases, such as sepsis, acute lung injury and multiple organ dysfunction syndrome. Efficient treatment to prevent inflammation is crucial in LPS-induced inflammatory diseases. Heat-clearing Chinese medicines (CMs) have been used to ameliorate LPS-induced inflammation in China for centuries. Heat-clearing CMs regulate inflammatory pathways, thereby inhibiting the release of inflammatory factors. This review aimed to introduce promising heat-clearing CMs countering LPS-induced inflammation in the last 5 years, exploring the underlying molecular mechanisms.
