RESUMEN
Oral diseases concern almost every individual and are a serious health risk to the popula-tion.The restorative treatment of tooth and jaw defects is an important means to achieve oral function and support the appearance of the contour.Based on the principle of"learning from the nature",Deng Xu-liang's group of Peking University School and Hospital of Stomatology has proposed a new concept of"microstructural biomimetic design and tissue adaptation of tooth/jaw materials"to address the worldwide problems of difficulty in treating dentine hypersensitivity,poor prognosis of restoration of tooth defects,and vertical bone augmentation of alveolar bone after tooth loss.The group has broken through the bottle-neck of multi-stage biomimetic technology from the design of microscopic features to the enhancement of macroscopic effects,and invented key technologies such as crystalline/amorphous multi-level assembly,ion-transportation blocking,and multi-physical properties of the micro-environment reconstruction,etc.The group also pioneered the cationic-hydrogel desensitizer,digital stump and core integrated restora-tions,and developed new crown and bridge restorative materials,gradient functionalisation guided tissue regeneration membrane,and electrically responsive alveolar bone augmentation restorative membranes,etc.These products have established new clinical strategies for tooth/jaw defect repair and achieved inno-vative results.In conclusion,the research results of our group have strongly supported the theoretical im-provement of stomatology,developed the technical system of oral hard tissue restoration,innovated the clinical treatment strategy,and led the progress of the stomatology industry.
RESUMEN
Glucagon-like peptide-1 receptor agonists (GLP-1RAs) have been widely used in diabetes and obese people in recent years, and they have also caused a series of adverse reactions, the most important of which is digestive system-related adverse reactions. The adverse reactions of the digestive system associated with GLP-1RAs involve the gastrointestinal, pancreatic, and biliary tracts; among them, nausea, vomiting, constipation, and diarrhea are the most common adverse reactions, which are the main reasons for drug withdrawal. The incidence of pancreatic and biliary system diseases is low, but there is no research evidence to exclude their association with GLP-1RAs. Tirzepatide appears on the market relatively late, and its safety still lacks sufficient real-world data. Medical staff should adopt active dietary guidance strategies for patients and strengthen medication education to help patients actively prevent and scientifically respond to adverse reactions in the digestive system.
RESUMEN
Comprehensively improving the new efficiency of high-quality development of public hospitals is the key top-level design for deepening the reform of public hospitals during the"14th Five-Year Plan"period.In view of the changes in the macro environment faced by public hospitals in recent years,such as the cancellation of the addi-tion of pharmaceutical consumables and the deep promotion of the reform of payment methods,as well as the out-standing problems existing at the micro level of public hospital operation,such as the separation of diagnosis and treatment business from economic operation activities,extensive decision-making methods,unreasonable alloca-tion of resources and urgent optimization of processes.By referring to relevant theories such as value management theory,a new"trinity"public hospital lean operation management model based on"integration of industry and fi-nance,lean operation and evidence-based decision-making"is explored and constructed.It breaks the relatively parallel operation barriers of clinical diagnosis and treatment business and economic operation management,innovates a new method of linear staff management with the integration of industry and finance,gives full play to the role of experts in governing hospitals,and integrates the professional committee system driven by"technology+manage-men"into the hospital decision-making staff system to provide data evidence-based basis for assisting the hospital leadership to make scientific decisions.
RESUMEN
Objective To measure and comprehensively analyze the operation efficiency of coronary heart disease Center of National Regional Medical Center for Cardiovascular Disease from the dimensions of department service in-come,department service quality,department service efficiency and department service benefit,and put forward targeted operation management optimization strategies based on the analysis results.Methods The operation effective-ness evaluation index of CHD centers in sample hospitals from 2020 to 2022 was measured by the empirical re-search method from the overall level of the center and the level of clinical departments,and the scores were com-pared and analyzed.Results From 2020 to 2022,the operation effectiveness evaluation index of CHD centers in sam-ple hospitals showed a good trend,increasing from 80.57 points to 82.86 points.The 3-year average score was 81.74;Among them,the score rate of department service benefit dimension is higher,the average is 96.64%;The score rate of department service efficiency was lower,with an average of 68.53%.The departments with the lowest operational efficiency scores from 2020 to 2022 are all A2 departments,with 74.39,72.41 and 75.89 scores respec-tively,mainly due to the relatively low scores of A2 departments in the dimensions of department service revenue and department service efficiency.Conclusion The results of clinical department operation effectiveness evaluation can provide the evidence-based basis for hospital operation management,and hospitals can establish benchmarking management departments according to the evaluation results and take targeted measures to improve the comprehen-sive operation efficiency of departments.
RESUMEN
Objective:To establish a risk prediction model for neonatal asphyxia in cesarean section and test its application effect.Methods:This was a retrospective study. We retrospectively analyzed the clinical data of 2 244 infants (modeling group) who were delivered by cesarean section in Affiliated Hospital of Weifang Medical University from April 2021 to December 2021. Newborns were divided into asphyxia group ( n=176) and non-asphyxia group ( n=2 068) according to the occurrence of neonatal asphyxia. Logistic regression was used to screen the risk factors of neonatal asphyxia in cesarean section and a line chart model was established to predict the risk. Another 683 neonates were selected as validation group for external validation of the model from January to March in 2022. Results:Five factors including preterm birth, fetal distress, fetal growth restriction, abnormal S/D value of umbilical artery and umbilical cord around the neck were included in the prediction model. The area under ROC curve of the modeling group was 0.902, the Youden index was 0.687, the sensitivity was 0.837, and the specificity was 0.850. Hosmer-lemeshow test showed that χ2=1.79, and P=0.877. In the validation group, the area under ROC curve was 0.823, the Youden index was 0.555, the sensitivity was 0.835, and the specificity was 0.720. It showed that the model had a good fitting effect and identification validity. Conclusions:The risk prediction model has a good clinical application value in the prediction of neonatal asphyxia in cesarean section, and provides reference for obstetricians to take preventive management measures of neonatal asphyxia in time.

All of the qualitative research on the real experience of skin-to-skin contact from the participation of caesarean section women were collected. The search time limit was from the establishment of the databases to May 2022. The JBI Critical Appraisal Tool for qualitative studies from Australia was used to evaluate the methodology quality of the included research, and the meta-aggregation was used to conduct the synthesis.Results:Totally 11 qualified studies were included and integrated into 49 valuable findings. Similar results were summarized into 12 groups, and 4 integrated results were synthesized, including the needs of cesarean section mothers; positive experience after skin-to-skin contact in caesarean section; skin-to-skin contact practice strengthen the role of mothers and promotes breastfeeding; difficulties and challenges of skin-to-skin contact during cesarean section.Conclusions:Skin-to-skin contact positively affects mother and infant delivered by cesarean section. Medical staff need to pay attention to the feelings and needs of cesarean section women participating in skin-to-skin contact, optimize information, environment, and humanistic support, and improve skin-to-skin contact practices. Medical institutions should rationally allocate obstetric resources to alleviate the difficulties faced by skin-to-skin contact practices.
RESUMEN
Resection of oral and maxillofacial tumors is often accompanied by the inferior alveolar nerve neurectomy, resulting in abnormal sensation in lower lip. It is generally believed that spontaneous sensory recovery in this nerve injury is difficult. However, during our follow-up, patients with inferior alveolar nerve sacrifice showed different degrees of lower lip sensory recovery. In this study, a prospective cohort study was conducted to demonstrate this phenomenon and analyze the factors influencing sensory recovery. A mental nerve transection model of Thy1-YFP mice and tissue clearing technique were used to explore possible mechanisms in this process. Gene silencing and overexpression experiments were then conducted to detect the changes in cell morphology and molecular markers. In our follow-up, 75% of patients with unilateral inferior alveolar nerve neurectomy had complete sensory recovery of the lower lip 12 months postoperatively. Patients with younger age, malignant tumors, and preservation of ipsilateral buccal and lingual nerves had a shorter recovery time. The buccal nerve collateral sprouting compensation was observed in the lower lip tissue of Thy1-YFP mice. ApoD was demonstrated to be involved in axon growth and peripheral nerve sensory recovery in the animal model. TGF-β inhibited the expression of STAT3 and the transcription of ApoD in Schwann cells through Zfp423. Overall, after sacrificing the inferior alveolar nerve, the collateral compensation of the ipsilateral buccal nerve could innervate the sensation. And this process was regulated by TGF-β-Zfp423-ApoD pathway.

Major natural disasters seriously threaten human life and health. After earthquakes and other catastrophes, survivors are often trapped in the confined spaces caused by the collapse of ground and buildings, with relative separation from the outside world, restricted access, complex environment, and oncoming or ongoing unsafety, leading to the rescue extremely difficult. In order to save lives and improve the outcome more efficiently in the confined spaces after natural disasters, it is very important to standardize and reasonably apply the trauma assessment and first aid workflow. This study focuses on trauma assessment and first aid. From the aspects of trauma assessment, vital signs stabilization, hemostasis and bandaging, post-trauma anti-infection, and the transportation of patients, a trauma first aid work process suitable for a small space of a major natural disaster is formed, It is helpful to realize the immediate and efficient treatment of trauma in the confined spaces after natural catastrophes, to reduce the rate of death and disability and improve the outcome of patients.

Sulfonylureas are widely used oral anti-diabetic drugs. However, its long-term usage effects on patients' lifespan remain controversial, with no reports of influence on animal longevity. Hence, the anti-aging effects of chlorpropamide along with glimepiride, glibenclamide, and tolbutamide were studied with special emphasis on the interaction of chlorpropamide with mitochondrial ATP-sensitive K+ (mitoK-ATP) channels and mitochondrial complex II. Chlorpropamide delayed aging in Caenorhabditis elegans, human lung fibroblast MRC-5 cells and reduced doxorubicin-induced senescence in both MRC-5 cells and mice. In addition, the mitochondrial membrane potential and ATP levels were significantly increased in chlorpropamide-treated worms, which is consistent with the function of its reported targets, mitoK-ATP channels. Increased levels of mitochondrial reactive oxygen species (mtROS) were observed in chlorpropamide-treated worms. Moreover, the lifespan extension by chlorpropamide required complex II and increased mtROS levels, indicating that chlorpropamide acts on complex II directly or indirectly via mitoK-ATP to increase the production of mtROS as a pro-longevity signal. This study provides mechanistic insight into the anti-aging effects of sulfonylureas in C. elegans.
RESUMEN
Objective:To investigate the clinical and genetic characteristics of genetic and metabolic infantile cholestatic hepatopathy (ICH), and to provide evidence for its diagnosis and treatment.Methods:Clinical data and follow-up outcomes of hospitalized children diagnosed with ICH in the Department of Gastroenterology, Children′s Hospital, Capital Institute of Pediatrics from January 2014 to December 2019 were retrospectively analyzed.Among the 80 children, 27 were female and 53 were male, with a mean age of onset of (39±18) days old.Children with confirmed etiology by high-throughput sequencing analysis were included in the genetic metabolic group (44 cases), and those with idiopathic neonatal cholestasis(INC) of unknown etiology after the systematic examination were included in the INC group (36 cases). The t-test or independent sample rank sum test was used to compare the laboratory test results and biochemical indexes.The infection rate of cytomegalovirus was compared by the Chi- square test. Results:(1) A total of 80 cases were included, and 44 cases (55.0%)were confirmed as INC by high-throughput sequencing.Among those with a positive molecular diagnosis, there were 23 cases of citrin deficiency (CD), 10 cases of Alagille syndrome (ALGS), 6 cases of progressive familial intrahepatic cholestasis (PFIC), 2 cases of congenital bile acid synthesis defect, 2 cases of Nieman Pick disease, and 1 case of cystic fibrosis.(2) Serum total bile acid (TBA) and activated partial prothrombin time (APTT) levels in the genetic metabolic group were significantly higher than those in the INC group (all P<0.05). TBA and APTT levels in genetic metabolites were 180.6 (115.5, 271.6) μmol/L and 40.6 (37.1, 45.2) s, respectively, which were 123.3 (98.8, 163.4) μmol/L and 34.8 (31.7, 40.1) s in INC group, respectively.There was no significant difference in the cytomegalovirus infection rate between the 2 groups ( P>0.05). (3)The pathological examination of liver tissue in the genetic metabolic group was worse than that in the INC group, with spot-like and fusion focal-like necrosis, and 5 cases (4 cases of ALGS and 1 case of CD) showed a reduced number of bile ducts in the portal area and lumen stenosis. Conclusions:CD, ALGS and PFIC are the common causes of genetic and metabolic ICH.Fundamental cause of cholestasis should be actively examined in children with cytomegalovirus infection.High-throughput sequencing is of great significance in the accurate diagnosis of ICH.

Objective:To investigate the effect of oxytocin on neonatal instinctive behavior expression and breast-feeding.Methods:A total of 71 pairs of parturient women and their newborns who delivered in the delivery room of the Affiliated Hospital of Weifang Medical College from February to May 2021 were selected. According to whether oxytocin induced labor, they were divided into the oxytocin group and the control group. Widstr?m nine stages was used to observe and record neonatal behavior. Breastfeeding was followed up 3 days and 3 months after delivery.Results:Totally 35 pairs in each group were included. In the oxytocin group, the occurrence time of neonatal head or head turning, hand in mouth, body moving to nipple, lips touching areola, licking nipple, nipple and effective sucking were (18.2 ± 5.4), (27.8 ± 8.3), (31.0 ± 10.1), (44.3 ± 14.5), (47.2 ± 15.6), (49.4 ± 16.3), (48.3 ± 13.6) min, which were significantly later than those in the control group (15.3 ± 5.3), (21.0 ± 8.1), (24.3 ± 9.0), (34.0 ± 11.4), (37.2 ± 11.9), (38.6 ± 11.8), (39.6 ± 8.7) min. The difference was statistically significant ( t values ranged from -3.10 to -2.17, P<0.05). The duration of neonatal awakening, activity, crawling and familiarity in the oxytocin group were (6.9 ± 3.2), (18.9 ± 9.3), (13.6 ± 7.9), (9.2 ± 5.1) min, which were significantly longer than those in the control group (5.1 ± 2.8), (12.3 ± 7.1), (10.3 ± 5.3), (6.7 ± 4.3) min; sucking stage duration in the oxytocin group was (35.1 ± 7.2) min, which was significantly shorter than that in the control group (39.6 ± 7.1) min; all the differences were statistically significant ( t values ranged from -3.25 to 2.28, P<0.05). The times of exclusive breast-feeding in the oxytocin group were (2.8 ± 3.1), (4.5 ± 3.3), (6.9 ± 3.0) at 24, 48 and 72 h postnatal, and the exclusive breastfeeding rate at 3 months after birth was 77.1%(27/35), which were significantly lower than those (7.6 ± 3.6), (8.9 ± 2.7), (10.3 ± 2.0) and 82.9%(29/35) in the control group, the differences were statistically significant ( t=6.05, 6.11, 5.48, χ2=0.36, P<0.05).

RESUMEN
As the main body of providing medical and health services, public hospitals always bear the important responsibility of maintaining people′s life and health.In the period of normal epidemic prevention and control, public hospitals are also facing a series of new situations, including changes in social environment, demands for reform and development and transformation of target functions. It is urgent to solve many problems, such as inadequate capacity building, continuous heavy operational pressure, impact on traditional modes, and constant adjustment of positioning and mode.Therefore, both the state and the government should adhere to the public welfare as the fundamental standpoint, accelerate the implementation of scientific planning and balanced distribution of medical resources, through the fundamental adjustment of the system and mechanism, and actively help public hospitals to choose the appropriate development mode, as soon as possible to relieve pressure rescue; Public hospitals should actively make use of the extensive application of Internet and other technologies and the huge potential contained in scientific and technological innovation to achieve high-quality development goals of improving quality and efficiency, and provide more powerful support for the overall national strategy.
RESUMEN
ObjectiveTo investigate the clinical features and gene mutation characteristics of neonatal intrahepatic cholestasis caused citrin deficiency (NICCD) in northern China. MethodsA total of 23 pediatric patients in northern China who were diagnosed with NICCD by blood tandem mass spectrometry and/or gene detection in Department of Gastroenterology, Children’s Hospital Affiliated to Capital Institute of Pediatrics, from January 2015 to December 2018 were enrolled as NICCD group, and 36 pediatric patients with idiopathic neonatal cholestasis (INC) who had unclarified etiology after a series of examinations during the same period of time were enrolled as INC group. A retrospective analysis was performed for the clinical manifestation, laboratory examination, pathology, blood/urine metabolic screening, and gene sequencing results of the pediatric patients in the NICCD group, and follow-up was performed to observe their outcome; biochemical parameters were compared between the two groups. The independent samples t-test was used for comparison of normally distributed continuous data, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data; the chi-square test was used for comparison of categorical data between groups. ResultsAmong the 23 patients in the NICCD group, 10 had hypoglycemia, 13 had hypoalbuminemia, 17 had hyperammonemia, and 15 had hyperlactacidemia; 15 had an increase in low-density lipoprotein, 6 had an increase in cholesterol, and 7 had an increase in triglyceride; 17 had prolonged prothrombin time, and 16 had prolonged activated partial thromboplastin time (APTT). Compared with the INC group, the NICCD group had significantly higher gamma-glutamyl transpeptidase (GGT), total bile acid (TBA), and APTT and a significantly lower albumin (Alb) level (Z=-2.487, Z=-3.528, t=3.532, t=-2.24, all P<0.05). For the patients with NICCD, blood tandem mass spectrometry showed that the most common abnormalities were the increased levels of arginine, citrulline, methionine, free carnitine, and long-chain acylcarnitine, while urinary gas chromatography showed the increased levels of 4-hydroxyphenyllactic acid, galactose, galactitol, and galactonic acid. Gene detection was performed for all 23 patients and identified 16 pathogenic mutations, among which 7 were newly discovered, namely ivs14-9a>G, c1640 G>A, c.762T>A, c.736delG, c.1098 T del, c.851G>A, and c.550G>A. Except for the 2 patients who were lost to follow-up, the levels of aminotransferases and bilirubin gradually returned to normal in 21 patients after 2-6 months of treatment; none of them showed delayed growth and development after being followed up to the age of 1 year, and 2 of them developed dietary preference (they liked fish and meat and did not like staple food). ConclusionAbnormalities of blood GGT, TBA, Alb, and APTT may provide ideas for the differential diagnosis of NICCD and INC. NICCD gene mutations in northern China are heterogeneous and most patients tend to have a good prognosis.
RESUMEN
High levels (> 100 ug/L) of arsenic are known to cause lung cancer; however, whether low (≤ 10 ug/L) and medium (10 to 100 ug/L) doses of arsenic will cause lung cancer or other lung diseases, and whether arsenic has dose-dependent or threshold effects, remains unknown. Summarizing the results of previous studies, we infer that low- and medium-concentration arsenic cause lung diseases in a dose-dependent manner. Arsenic trioxide (ATO) is recognized as a chemotherapeutic drug for acute promyelocytic leukemia (APL), also having a significant effect on lung cancer. The anti-lung cancer mechanisms of ATO include inhibition of proliferation, promotion of apoptosis, anti-angiogenesis, and inhibition of tumor metastasis. In this review, we summarized the role of arsenic in lung disease from both pathogenic and therapeutic perspectives. Understanding the paradoxical effects of arsenic in the lungs may provide some ideas for further research on the occurrence and treatment of lung diseases.

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.

ObjectiveThe aim of the study is to analyze the latent class of basic reproduction number (R0) trend of 2019 novel coronavirus disease (COVID-19) in major endemic areas of China. MethodsThe provinces that reported more than 500 cases of COVID-19 till February 18, 2020 were selected as the major endemic area. The Verhulst model was used to fit the growth rate of cumulative confirmed cases. The R0 of COVID-19 was calculated using the parameters of severe acute respiratory syndrome (SARS) and COVID-19, respectively. The latent class of R0 was analyzed using a latent profile analysis model. ResultsThe median R0 calculated from SARS and COVID-19 parameters were 1.84 - 3.18 and 1.74 - 2.91, respectively. The R0 calculated from the SARS parameters was greater than that of calculated from the COVID-19 parameters (Z = -4.782 - -4.623, P < 0.01). Both R0 can be divided into three latent classes. The initial value of R0 in class 1 (Shandong Province, Sichuan Province and Chongqing Municipality) was relatively low and decreases slowly. The initial value of R0 in class 2 (Anhui Province, Hunan Province, Jiangxi Province, Henan Province, Zhejiang Province, Guangdong Province and Jiangsu Province) was relatively high and decreases rapidly. Moreover, the initial value of R0 of class 3 (Hubei Province) was between that of class 1 and class 2, but the higher level of R0 lasts longer and decreases slowly. ConclusionThe results indicated that overall trend of R0 has been falling with the strengthening of Chinas comprehensive prevention and control measures for COVID-19, however, presents regional differences.
RESUMEN
Objective:To investigate the status of horizontal violence between structural authorization and operating room nurses, and to analyze the influence of structural authorization on horizontal violence among operating room nurses, and to provide reference for improving the occurrence of horizontal violence among nurses in operating room.Methods:From May to June 2019, a convenient sampling method was used to select 198 operating room nurses from 4 third-grade hospitals in Beijing as the research object. The general data questionnaire, structural authorization scale, and horizontal violence questionnaire were used. Questionnaire.Results:The total score of structural authorization scale was (55.37±9.78) points. The total score of horizontal violence among nurses in operation room was (54.69±9.38) points. The structural authorization was negatively correlated with the horizontal violence between nurses in the operating room ( r=-0.786, P<0.05). Conclusion:Structural authorization can affect horizontal violence among nurses in the operating room. The head nurse should construct a positive working environment that is conducive to authorization, thus effectively reducing the occurrence of horizontal violence among nurses.
RESUMEN
We used the epidemic data of COVID-19 published on the official website of the municipal health commission in Anhui province. We mapped the spatiotemporal changes of confirmed cases, fitted the epidemic situation by the population growth curve at different stages and took statistical description and analysis of the epidemic situation in Anhui province. It was found that the cumulative incidence of COVID-19 was 156/100 000 by February 18, 2020 and the trend of COVID-19 epidemic declined after February 7, changing from J curve to S curve. The actual number of new cases began to decrease from February 2 to February 4 due to the time of case report and actual onset delayed by 3 to 5 days.
RESUMEN
Pediatric cough is a heterogeneous condition in terms of symptoms and the underlying disease mechanisms. Symptom phenotypes hold complicated interactions between each other to form an intricate network structure. This study aims to investigate whether the network structure of pediatric cough symptoms is associated with the prognosis and outcome of patients. A total of 384 cases were derived from the electronic medical records of a highly experienced traditional Chinese medicine (TCM) physician. The data were divided into two groups according to the therapeutic effect, namely, an invalid group (group A with 40 cases of poor efficacy) and a valid group (group B with 344 cases of good efficacy). Several well-established analysis methods, namely, statistical test, correlation analysis, and complex network analysis, were used to analyze the data. This study reports that symptom networks of patients with pediatric cough are related to the effectiveness of treatment: a dense network of symptoms is associated with great difficulty in treatment. Interventions with the most different symptoms in the symptom network may have improved therapeutic effects.
