ABSTRACT

Objective: To summarize the clinical features and prognosis of Budd-Chiari syndrome with hepatopulmonary syndrome (HPS) in children. Methods: The clinical data of a child who had Budd-Chiari syndrome with HPS treated at the Department of Pediatrics of the First Affiliated Hospital of Zhengzhou University in December 2016 was analyzed retrospectively. Taking "Budd-Chiari syndrome" and "hepatopulmonary syndrome" in Chinese or English as the keywords, literature was searched at CNKI, Wanfang, China Biomedical Literature Database and PubMed up to July 2023. Combined with this case, the clinical characteristics, diagnosis, treatment and prognosis of Budd-Chiari syndrome with HPS in children under the age of 18 were summarized. Results: A 13-year-old boy, presented with cyanosis and chest tightness after activities for 6 months, and yellow staining of the skin for 1 week. Physical examination at admission not only found mild yellow staining of the skin and sclera, but also found cyanosis of the lips, periocular skin, and extremities. Laboratory examination showed abnormal liver function with total bilirubin 53 μmol/L, direct bilirubin 14 μmol/L, and indirect bilirubin 39 μmol/L, and abnormal blood gas analysis with the partial pressure of oxygen of 54 mmHg (1 mmHg=0.133 kPa), the partial pressure of carbon dioxide of 31 mmHg, and the alveolar-arterial oxygen gradient of 57 mmHg. Hepatic vein-type Budd-Chiari syndrome, cirrhosis, and portal hypertension were indicated by abdominal CT venography. Contrast-enhanced transthoracic echocardiography (CE-TTE) was positive. After symptomatic and supportive treatment, this patient was discharged and received oxygen therapy outside the hospital. At follow-up until March 2023, there was no significant improvement in hypoxemia, accompanied by limited daily activities. Based on the literature, there were 3 reports in English while none in Chinese, 3 cases were reported. Among a total of 4 children, the chief complaints were dyspnea, cyanosis, or hypoxemia in 3 cases, and unknown in 1 case. There were 2 cases diagnosed with Budd-Chiari syndrome with HPS at the same time due to respiratory symptoms, and 2 cases developed HPS 1.5 years and 8.0 years after the diagnosis of Budd-Chiari syndrome respectively. CE-TTE was positive in 2 cases and pulmonary perfusion imaging was positive in 2 cases. Liver transplantation was performed in 2 cases and their respiratory function recovered well; 1 case received oxygen therapy, with no improvement in hypoxemia; 1 case was waiting for liver transplantation. Conclusions: The onset of Budd-Chiari syndrome with HPS is insidious. The most common clinical manifestations are dyspnea and cyanosis. It can reduce misdiagnosis to confirm intrapulmonary vascular dilatations with CE-TTE at an early stage. Liver transplantation is helpful in improving the prognosis.

ABSTRACT

OBJECTIVE@#Tissue uptake and distribution of nano-/microplastics was studied at a single high dose by gavage in vivo.@*METHODS@#Fluorescent microspheres (100 nm, 3 μm, and 10 μm) were given once at a dose of 200 mg/(kg∙body weight). The fluorescence intensity (FI) in observed organs was measured using the IVIS Spectrum at 0.5, 1, 2, and 4 h after administration. Histopathology was performed to corroborate these findings.@*RESULTS@#In the 100 nm group, the FI of the stomach and small intestine were highest at 0.5 h, and the FI of the large intestine, excrement, lung, kidney, liver, and skeletal muscles were highest at 4 h compared with the control group ( P < 0.05). In the 3 μm group, the FI only increased in the lung at 2 h ( P < 0.05). In the 10 μm group, the FI increased in the large intestine and excrement at 2 h, and in the kidney at 4 h ( P < 0.05). The presence of nano-/microplastics in tissues was further verified by histopathology. The peak time of nanoplastic absorption in blood was confirmed.@*CONCLUSION@#Nanoplastics translocated rapidly to observed organs/tissues through blood circulation; however, only small amounts of MPs could penetrate the organs.

ABSTRACT

Objective To investigate whether endoscopic ultrasonography (EUS) can be an alternative method for diagnostic endoscopic retrograde cholangiopancreatography (ERCP) by comparing the ability of EUS versus CT and transabdominal ultrasonography (TUS) in the diagnosis of muddy stones of the common bile duct. Methods A prospective study was conducted for 53 patients suspected of muddy stones of the common bile duct who attended Nanxishan Hospital of Guangxi Zhuang Autonomous Region from July 2019 to December 2021, and all patients underwent EUS, TUS, and CT before ERCP. With ERCP and endoscopic sphincterotomy (EST) for removing muddy stones of the common bile duct as the gold standard for the diagnosis of muddy stones of the common bile duct, EUS, TUS, and CT were compared in terms of their ability to display the muddy stones of the common bile duct. The chi-square test or the Fisher's exact test was used for comparison of categorical data between groups. Results In the 53 patients, EUS, TUS, and CT had a positive rate of 88.68%, 50.94%, and 62.26%, respectively, in detecting muddy stones of the common bile duct. As for the positive results confirmed by EST under ERCP, EUS had a sensitivity of 93.75%, a specificity of 60.00%, and an accuracy of 90.57% in detecting muddy stones of the common bile duct, while TUS had a sensitivity of 56.25%, a specificity of 100.00%, and an accuracy of 60.38% and CT had a sensitivity of 66.67%, a specificity of 80.00%, and an accuracy of 67.92%. There was a significant difference between EUS and CT in the accuracy in detecting muddy stones of the common bile duct ( χ 2 =8.26, P =0.004), and there was also a significant difference in diagnostic accuracy between EUS and TUS ( χ 2 =13.05, P < 0.001). Conclusion EUS is more accurate than TUS and CT in the diagnosis of muddy stones of the common bile duct, and instead of ERCP, EUS is thus recommended for suspected muddy stones of the common bile duct when TUS and CT fail to identify the lesions in clinical practice, so as to make a confirmed diagnosis and reduce related costs and complications.

ABSTRACT

OBJECTIVES@#To study the effects of infantile positional plagiocephaly on the growth and neural development.@*METHODS@#A retrospective study was conducted on the medical data of 467 children who underwent craniographic examination and were followed up to 3 years of age in Peking University Third Hospital from June 2018 to May 2022. They were divided into four groups: mild positional plagiocephaly (n=108), moderate positional plagiocephaly (n=49), severe positional plagiocephaly (n=12), and normal cranial shape (n=298). The general information of the four groups and the weight, length, head circumference, visual acuity screening results, hearing test results, and the scores of Pediatric Neuropsychological Developmental Scales/Gesell Developmental Schedules of the four groups from 6 to 36 months old were compared.@*RESULTS@#The rates of adverse perinatal factors, congenital muscular torticollis, and supine fixed sleeping posture in the mild, moderate, and severe positional plagiocephaly groups were higher than the normal cranial group (P<0.05). There was no significant difference in weight, length, and head circumference among the four groups at 6, 12, 24 and 36 months of age (P>0.05). The incidence rate of abnormal vision in the severe positional plagiocephaly group was higher than that in the mild positional plagiocephaly, moderate positional plagiocephaly and normal cranial shape groups at 24 and 36 months of age (P<0.05). The scores of the Pediatric Neuropsychological Developmental Scales at 12 and 24 months of age and the scores of the Gesell Developmental Schedules at 36 months of age in the severe positional plagiocephaly group were lower than those in the mild positional plagiocephaly, moderate positional plagiocephaly and normal cranial shape groups, but the difference was not statistically significant (P>0.05).@*CONCLUSIONS@#Adverse perinatal factors, congenital muscular torticollis, and supine fixed sleeping position may be associated with infantile positional plagiocephaly. Mild or moderate positional plagiocephaly has no significant impact on the growth and neural development of children. Severe positional plagiocephaly have adverse effects on the visual acuity. However, it is not considered that severe positional plagiocephaly can affect the neurological development.

ABSTRACT

This study aims to provide evidence for clinical practice by systematically reviewing the efficacy and safety of Gusongbao preparation in the treatment of primary osteoporosis(POP). The relevant papers were retrieved from four Chinese academic journal databases and four English academic journal databases(from inception to May 31, 2022). The randomized controlled trial(RCT) of Gusongbao preparation in the treatment of POP was included after screening according to the inclusion and exclusion criteria. The quality of articles was evaluated using risk assessment tools, and the extracted data were subjected to Meta-analysis in RevMan 5.3. A total of 657 articles were retrieved, in which 15 articles were included in this study, which involved 16 RCTs. A total of 3 292 patients(1 071 in the observation group and 2 221 in the control group) were included in this study. In the treatment of POP, Gusongbao preparation+conventional treatment was superior to conventional treatment alone in terms of increasing lumbar spine(L2-L4) bone mineral density(MD=0.03, 95%CI[0.02, 0.04], P<0.000 01) and femoral neck bone mineral density, reducing low back pain(MD=-1.69, 95%CI[-2.46,-0.92], P<0.000 1) and improving clinical efficacy(RR=1.36, 95%CI[1.21, 1.53], P<0.000 01). Gusongbao preparation was comparable to similar Chinese patent medicines in terms of improving clinical efficacy(RR=0.95, 95%CI[0.86, 1.04], P=0.23). Gusongbao preparation was inferior to similar Chinese patent medicines in reducing traditional Chinese medicine syndrome scores(MD=1.08, 95%CI[0.44, 1.71], P=0.000 9) and improving Chinese medicine syndrome efficacy(RR=0.89, 95%CI[0.83, 0.95], P=0.000 4). The incidence of adverse reactions of Gusongbao preparation alone or combined with conventio-nal treatment was comparable to that of similar Chinese patent medicines(RR=0.98, 95%CI[0.57, 1.69], P=0.94) or conventio-nal treatment(RR=0.73, 95%CI[0.38, 1.42], P=0.35), and the adverse reactions were mainly gastrointestinal discomforts. According to the available data, Gusongbao preparation combined with conventional treatment is more effective than conventional treatment alone in increasing lumbar spine(L2-L4) bone mineral density and femoral neck bone mineral density, reducing low back pain, and improving clinical efficacy. The adverse reactions of Gusongbao preparation were mainly gastrointestinal discomforts, which were mild.

ABSTRACT

Objective: Based on a cohort and intervention study of the Eastern Chinese Student Surveillance, Cohort and Intervention Study (ES-SCI), this research aims to explore the correlation between monitor of the school environment and longitudinal data on myopia and provide evidence for the government myopia intervention strategy. Methods: This survey adopts the stratified cluster sampling method with the school as the unit. Students from grade 1 to grade 3 were selected according to the whole class to monitor the school environment in the classroom. Students will use the full-automatic computer optometer (TOPCON RM800) to conduct optometry from 2019 to 2021 under the condition of mydriasis to perform refractive eye examinations. Meantime eye axis length monitoring was also conducted. Cox proportional risk regression model was used to explore the relationship between school environmental monitoring and the occurrence and development of students' myopia. Results: From 2019 to 2021, 2 670 students from 77 classrooms participated in the observation study. The students' diopter after right/left eye mydriasis decreased in varying degrees (P<0.001), and the axial length of the right/left eye increased in various degrees (P<0.001). The weighted qualified rate of per capita area of primary school classrooms increased from 18.0% in 2019 to 26.0% in 2021, the weighted average illuminance pass rate of blackboard surface increased from 23.8% in 2019 to 26.4% in 2021, and the weighted average illuminance pass rate of classroom table decreased from 86.7% in 2019 to 77.5% in 2021. The trend chi-square test was significant (P<0.05). Cox proportional risk regression showed that after correcting for the grade, gender, parental myopia, diet, sleep, near work (sitting posture, working time, electronic mobile equipment, eye exercises), and outdoor activities, the per capita area of 1.36- m2 was the protective factor of eye axis length (HR=0.778, 95%CI: 0.659-0.918, P=0.003); The average reflection ratio of blackboard 0.15-0.19 was the protective factor of eye axis length (HR=0.685, 95%CI: 0.592-0.793, P<0.001); The average illumination of the blackboard 150-, 300-, 500- lx was the protective factor of the eye axis length (HR=0.456, 95%CI: 0.534-0.761, P<0.001; HR=0.794, 95%CI: 0.705-0.895, P<0.001; HR=0.690, 95%CI: 0.619-0.768, P<0.001). The blackboard evenness 0.40-0.59 was the risk factor of eye axis length (HR=1.528, 95%CI: 1.018-2.293, P=0.041), and the blackboard evenness 0.80- was the protection factor of eye axis length (HR=0.542, 95%CI: 0.404-0.726, P<0.001). The evenness of the desktop 0.40-0.59 was the protective factor of eye axis length (HR=0.820, 95%CI: 0.698-0.965, P=0.017). The average illuminance of 150-, 300-, 500- lx was the protective factor of a diopter (HR=0.638, 95%CI: 0.534-0.761, P<0.001; HR=0.911, 95%CI: 0.848-0.978, P=0.011; HR=0.750, 95%CI: 0.702-0.801, P<0.001). The average illumination of desktop 500- lx was a protective factor of a diopter (HR=0.855, 95%CI: 0.763-0.958, P=0.007). Conclusion: School environmental monitoring indicators, such as meeting per capita area standards, passing blackboard, and desk top-related indicators, all play protective effects on myopia development in students.

ABSTRACT

Objective:To explore the changes of disease burden and risk factors of chronic kidney disease (CKD) due to type 1 and type 2 diabetes mellitus in China from 1990 to 2019, and to provide reference data for the prevention and control of diabetic kidney disease (DKD).Methods:The Chinese DKD data were obtained from the 2019 Global Burden of Disease (GBD) database. The morbidity, prevalence, mortality, years lived with disability (YLD), years of life lost (YLL), and disability-adjusted life year (DALY) were used to compare the disease burden of CKD due to type 1 and type 2 diabetes mellitus from 1990 to 2019. In addition, the risk factors of DKD were analyzed.Results:The numbers of CKD patients due to type 1 and type 2 diabetes mellitus in China were 574 (95% UI 495-665) and 31 076 (95% UI 28 152-33 909) thousand, and the numbers of new cases were 9 (95% UI 8-11) and 434 (95% UI 390-481) thousand in 2019, respectively. The numbers of death were 13 (95% UI 8-18) and 63 (95% UI 50-77) thousand, respectively. The age groups with the largest number of patients and new cases of CKD due to type 1 diabetes mellitus were 30-34 years old and <5 years old, respectively. The age group with the largest number of patients and new cases of CKD due to type 2 diabetes mellitus were 50-54 years old and 70-74 years old, respectively. From 1990 to 2019, the age-standardized prevalence rate of DKD patients in China was relatively stable, but the age-standardized incidence rate and YLD rate showed an upward trend, while the age-standardized mortality rate, YLL rate, and DALY rate showed a downward trend. The main risk factors associated with DKD death were high fasting plasma glucose, kidney dysfunction, high systolic blood pressure, high body mass index, high sodium diet, and lead exposure. The proportions of DKD death caused by high systolic blood pressure and high body mass index in the Chinese population were still increasing. Conclusions:From 1990 to 2019, the age-standardized incidence and YLD rate of DKD in China shows an upward trend, while the age-standardized prevalence rate is relatively stable, and the age-standardized mortality rate, YLL rate, and DALY rate show a decreasing trend. High fasting glucose, renal failure, high systolic blood pressure, high body mass index, high sodium diet, and lead exposure are risk factors associated with death in DKD patients. With the progress of aging, the disease burden of DKD in China will continuously increase. Future work should be focused on population-specific interventions, taking into consideration the risk factors identified within the study.

ABSTRACT

The aim of this study was to elucidate the protective effect of arbutin on cisplatin (Cis) induced renal tubular epithelial cell injury and its mechanism. Cell counting kit-8 was used to detect the viability of renal tubular epithelial cells. The toxicity of arbutin on renal tubular epithelial cells at different concentrations and the appropriate concentration of arbutin to protect cells against cisplatin were observed. The renal tubular epithelial cells were divided into control group, arbutin group, Cis group and arbutin+Cis group. Flow cytometry, quantitative real-time PCR and Western blotting were used to detect the levels of apoptosis and inflammation. The results showed that arbutin had no significant toxic effect on renal tubular epithelial cells in the mentioned concentration range (0-200 μmol/L). When the concentration of arbutin exceeded 100 μmol/L, it showed a protective effect on renal tubular epithelial cells. Arbutin intervention significantly reduced cisplatin-induced apoptosis of renal tubular epithelial cells and the increase of inflammation-related molecules p-p65 and interleukin-18. In addition, arbutin intervention reversed the cisplatin-induced reduction of Bcl-2 in renal tubular epithelial cells. These findings suggest that arbutin can attenuate cisplatin-induced renal tubular epithelial cell injury through anti-apoptotic and anti-inflammatory responses, which may be expected to be a new potential therapeutic drug for acute kidney injury.

ABSTRACT

The R-loop is a three-stranded nucleic acid structure, which consists of a RNA: DNA hybrid and a DNA single strand. R-loop can be divided into two types: physiological and pathological. The physiological R-loop is involved in many physiological processes such as DNA replication, transcription, and gene expression regulation, while the pathological R-loop induces DNA damage and genome rearrangement. There are many factors that affect the formation of R-loops. Unregulated R-loops destroy genomic stability by interfering with DNA replication and double-strand DNA break repair, and can cause cancer. Therefore, the regulation of R-loops is very important. RNA/ DNA helicase Senataxin (SETX), DEAD-box helicase 5 (DDX5), ribonuclease H (RNase H) and DNA topoisomerase I (topo) play an important role in regulating the balance of R-loops in vivo. Among them, SETX is one of the most characteristic R-loop decomposing enzymes, which can dissolve the R-loops produced during transcriptional termination sites, replication-transcriptional conflicts and DNA damage repair. Senataxin mutations will lead to ataxia with eye movement apraxia type 2 (AOA2) and amyotrophic lateral sclerosis type 4 (ALS4). Currently there are still many unsolved issues, although many in-depth studies of R-loops have been carried out. Therefore, the structure and function of physiological and pathological R-loops still need to be further explored. This review mainly focuses on the definition and classification of R-loops, the factors that affect the formation of R-loops, the influence of R-loops on genomic stability and R-loop-related diseases, and explores the possibility of using R-loops as a therapeutic target in the future.

ABSTRACT

Objective:To explore accurate prenatal diagnosis, full-coverage graded counseling and follow-up for the fetus with cardiac birth defects (CBD).Methods:CBD fetus diagnosed prenatal by echocardiography from January 2018 to December 2020 in Guangdong Provincial People's Hospital were enrolled. Fetal CBD was graded (Ⅰ-Ⅵ) according to prognosis and possible operation time after birth, and the classification criteria and common diseases included were proposed. After the prenatal grading counseling, the outcome of the fetus was followed-up. The induced labor rate, live birth rate, prenatal and postnatal ultrasound diagnosis coincidence rate and other indicators were calculated. The disease composition ratio, prognosis of fetus with different grades and the outcome of integrated treatment were analyzed.Results:The detection rate of fetal CBD was up to 16.2% (1 971/12 188), 30 cases of which were excluded. A total of 1 941 cases were included in this study, including 196 cases (10.1%) of gradeⅠ, 433 cases (22.3%) of gradeⅡ, 615 cases (31.7%) of grade Ⅲ, 261 cases (13.4%) of grade Ⅳ, 388 cases (20.0%) of gradeⅤ, 48 cases (2.5%) of grade Ⅵ. Grade Ⅱ and gradeⅢ (the operation time was within 1 year after birth) accounted for 54.0% (1 048/1 941). The distribution of some diseases in different grades had obvious proportion advantage, which was representative. Among 1 747 CBD fetus, 736 cases (induced labor rate 42.1%) chose to terminate pregnancy due to CBD. Of the 1 010 live births, 975 cases (96.5%) had the same prenatal and postnatal diagnosis, 3 cases were missed diagnosis and 32 cases were misdiagnosed. The diagnostic accuracy of live births with severe and complex congenital heart disease was 383 out of 389 (98.5%). A total of 258 cases have received surgery or intervention. The age at the time of surgery or intervention was different among grades( χ2 =47.3, P<0.001). With the improvement of prognosis from gradeⅠ to Ⅴ, the live birth rate increased and the induced labor rate decreased accordingly; the difference between grades was significant( χ2 =623.6, P<0.001). Conclusions:Prenatal diagnosis and graded counseling is important in the integrated model. Fetal CBD grading could refine post-natal treatment strategies, guide delivery decisions and become an evaluation standard.

ABSTRACT

Objective:To summarize and analyze the efficacy, experience and follow-up results of 300 cases of transposition of the great arteries (TGA) intervened by arterial switch operation.Methods:It was a retrospective, single-center study involving 300 TGA patients intervened by arterial switch operation between January 2010 and December 2017 in Guangdong Provincial People′s Hospital.Their clinical data were retrospectively analyzed.There were 236 male patients and 64 females.Among them, 128 cases (42.7%) were TGA with ventricular septal defect (TGA/VSD), and 172 cases (57.3%) were TGA with intact ventricular septal defect (TGA/IVS). The mean age and weight at operation were (23.8±39.2) cases days, and (3.5±0.8) kg, respectively.There were 193 cases (64.3%) with usual coronary artery patterns, and 107 cases (35.7%) with unusual coronary artery patterns.Among the 107 cases with unusual coronary artery patterns, 21 cases (7.0%) were involved with the intramural coronary artery, and 17 (5.7%) presented the single-ostium coronary pattern.Non normal distribution data were used the Mann- Whitney U test.Categorical measures were compared by Chi- square test or Fisher′ s exact test.Survival probability and freedom from events were calculated by the Kaplan-Meier method, and difference in survival probability by the Log Rank test. Results:All patients were successfully intervened by arterial switch operation, 73.3% of patients with TGA/IVS underwent the surgery within 3 weeks after birth, and 85.9% of patients with TGA/VSD underwent surgery within 3 months.The mean cardiopulmonary bypass time and aortic occlusion time were (193±68) min, and (122±39) min, respectively.Twenty-five patients (8.3%) died in hospital.Thirty cases had low cardiac output syndrome, 1 implanted with a permanent pacemaker due to complete atrioventricular block.A total of 254 patients were followed up for 1 month to 10 years.Three patients with single-ostium coronary pattern died at the follow-up period.The 5-year and 10-year survival rates were both 90.7%.During the follow-up, 49 cases (49/254 cases, 19.3%) had pulmonary artery stenosis, 66 cases (66/254 cases, 26.0%) had aortic valve regurgitation, 47 cases (47/254 cases, 18.5%) had pulmonary valve regurgitation, and 4 (4/254 cases, 1.6%) had aortic anastomotic stenosis.Among the 21 patients (21/254 cases, 8.3%) requiring reintervention, 17 patients (17/254 cases, 6.7%) underwent a total of 18 reinterventions, including 12 interventions of pulmonary artery plasty, 4 of percutaneous balloon pulmonary valvuloplasty, 1 of aortic reconstruction at anastomosis and 1 of pacemaker exchange due to battery exhaustion.Conclusions:Arterial switch operation is the optimal treatment for TGA.The long-term follow-up results of arterial switch operation are satisfactory in TGA children, with a low risk of long-term reoperation.

ABSTRACT

OBJECTIVE@#To reveal the neuroprotective effect and the underlying mechanisms of a mixture of the main components of Panax notoginseng saponins (TSPN) on cerebral ischemia-reperfusion injury and oxygen-glucose deprivation/reoxygenation (OGD/R) of cultured cortical neurons.@*METHODS@#The neuroprotective effect of TSPN was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay, flow cytometry and live/dead cell assays. The morphology of dendrites was detected by immunofluorescence. Middle cerebral artery occlusion (MCAO) was developed in rats as a model of cerebral ischemia-reperfusion. The neuroprotective effect of TSPN was evaluated by neurological scoring, tail suspension test, 2,3,5-triphenyltetrazolium chloride (TTC) and Nissl stainings. Western blot analysis, immunohistochemistry and immunofluorescence were used to measure the changes in the Akt/mammalian target of rapamycin (mTOR) signaling pathway.@*RESULTS@#MTT showed that TSPN (50, 25 and 12.5 µ g/mL) protected cortical neurons after OGD/R treatment (P<0.01 or P<0.05). Flow cytometry and live/dead cell assays indicated that 25 µ g/mL TSPN decreased neuronal apoptosis (P<0.05), and immunofluorescence showed that 25 µ g/mL TSPN restored the dendritic morphology of damaged neurons (P<0.05). Moreover, 12.5 µ g/mL TSPN downregulated the expression of Beclin-1, Cleaved-caspase 3 and LC3B-II/LC3B-I, and upregulated the levels of phosphorylated (p)-Akt and p-mTOR (P<0.01 or P<0.05). In the MCAO model, 50 µ g/mL TSPN improved defective neurological behavior and reduced infarct volume (P<0.05). Moreover, the expression of Beclin-1 and LC3B in cerebral ischemic penumbra was downregulated after 50 µ g/mL TSPN treatment, whereas the p-mTOR level was upregulated (P<0.05 or P<0.01).@*CONCLUSION@#TSPN promoted neuronal survival and protected dendrite integrity after OGD/R and had a potential therapeutic effect by alleviating neurological deficits and reversing neuronal loss. TSPN promoted p-mTOR and inhibited Beclin-1 to alleviate ischemic damage, which may be the mechanism that underlies the neuroprotective activity of TSPN.

ABSTRACT

Objective@#To investigate the changes of school absenteeism among students received Nutrition Improvement Program for Rural Compulsory Education Student (NIPCES), and to provide basic data for further nutritional health improvement for rural students.@*Methods@#Among 699 NIPCES monitored counties among 22 provinces across western and central China, 10%-30% of elementary and junior high schools were randomly selected as monitoring schools within each stratification according to the food supply pattern (school canteen, company and mix) in each county, school absenteeism information were collected and analyzed from 2012 to 2017.@*Results@#The total rate of student absenteeism was 26.0 per 10 000. From 2012 to 2016, it dropped from 30.8 per 10 000 to 23.4 per 10 000 year by year, but it increased again in 2017(28.2 per 10 000). The rate of school absenteeism in the western region (29.4 per 10 000) was higher than that in the central region (21.5 per 10 000); The sick leave rate (15.0 per 10 000) of primary school students was higher than that of junior high school students (13.4 per 10 000), and the rate of personal leave absences (16.9 per 10 000) of junior high school students was higher than that of elementary school students(9.9 per 10 000); the absentees rate in mixed-food supply schools (28.5 per 10 000) was higher than that in canteen food supply schools(26.4 per 10 000), the latter was higher than that of company food supply schools(25.0 per 10 000). The rate of sick leave absenteeism was highest in December(18.4 per 10 000), and the rate of personal leave absenteeism in June was highest(14.6 per 10 000).@*Conclusion@#The rate of school absenteeism among students in the NIPCES area showed an overall downward trend year by year. The absentee rate of students varies by regions, grade, food supply patterns and school locations.

ABSTRACT

Objective: To investigate the independent risk factors of cardiorenal syndrome type 1 (CRS1) in patients with acute myocardial infarction (AMI) and to build a predictive equation for the development of CRS1 in these patients. Method: Consecutive inpatients with AMI, who hospitalized from January 2017 to December 2018 in the Hunan Provincial People's Hospital, were enrolled in this case-control study. Patients were divided into CRS1 group and non-CRS1 group according to the presence or absence of CRS1.The clinical data were collected through the electronic medical record system of Hunan Provincial People's Hospital. The matching process was conducted with a minimum-distance scoring method and a 1∶1 match between the CRS1 group and the no-CRS1 group, the propensity score was calculated through the logistic regression model. Factors with statistically significant differences in univariate analysis were included in the multivariate logistic regression model to analyze the risk factors of AMI patients with CRS1, then the independent risk factors were used to establish a predicting equation for CRS1 by logistic regression function for model building. Area under the curve (AUC) value and the best cut-off value of the combined predictors was determined according to the ROC curve. Python 3.8 software was used to perform 10-fold cross-validation on modeling samples. Results: A total of 942 patients were included, there were 113 cases in CRS1 group and 829 cases in non-CRS1 group. Ultimately, 99 CRS1 patients were successfully matched to 99 non-CRS1 patient using 1∶1 matching. After propensity score matching, the baseline age and sex along with heart rate, mean arterial pressure, percentage of people with a history of diabetes, hypertension, ST-segment elevation myocardial infarction, myocardial ischemia time, angiotensin converting enzyme inhibitors or angiotensin Ⅱ receptor blockers use, and β receptor blocker use were similar between the two groups(all P>0.05). The contrast agent dosage was also similar between the two groups (P=0.266). The peak cardiac troponin I (cTnI), N-terminal pro-brain natriuretic peptide(NT-proBNP), white blood cell count, base estimated glomerular filtration rate (eGFR), albumin and hemoglobin levels were statistically significant between the two groups (all P<0.05). Multivariate logistic regression analysis showed that decreased baseline eGFR, increased NT-proBNP, peak cTnI concentrations and white blood cell count were independent risk factors of CRS1 in AMI patients (all P<0.01).The predicting equation of the combined predictor was established by transforming the logistic model equation, L=0.031×cTnI+0.000 2×NT-proBNP-0.024×eGFR+0.254×white blood cell count, where L represented the combined predictor. ROC curve analysis indicated that the AUC of the peak cTnI, NT-proBNP, baseline eGFR, white blood cell count, and combined predictor were 0.76, 0.85, 0.79, 0.81, and 0.92 respectively (all P<0.05), and the cutoff value of combined predictor was 2.6. The AUC of ROC curve after the model's ten-fold cross validation was 0.89. Conclusions: Decreased baseline eGFR, increased NT-proBNP, peak cTnI concentrations and white blood cell count are the independent risk factors for CRS1 in AMI patients. The combined predictor equation based on the above 4 biomarkers presents a good predictive value for CRS1 in AMI patients.

ABSTRACT

Objective: To evaluate the anti-inflammatory activity of Crotalaria ferruginea extract (CFE) and its mechanism. Methods: An intratracheal lipopolysaccharide (LPS) instillation-induced acute lung injury (ALI) model was used to study the anti-inflammatory activity of CFE in vivo. The LPS-induced shock model was used to analyze the effect of CFE on survival. LPS-stimulated RAW264.7 cell model was used to investigate the anti-inflammatory activity of CFE in vitro and the effects on mitogen-Activated protein kinase (MAPK) or nuclear factor-κB (NF-κB) signaling pathways. Results: CFE administration decreased the number of inflammatory cells, reduced the levels of tumor necrosis factor-α (TNF-A), monocyte chemotactic protein-1 (MCP-1), interleukin-6 (IL-6), and interferon-γ, and diminished protein content in the bronchoalveolar lavage fluid of mice. CFE also reduced lung wet-To-dry weight ratio, myeloperoxidase, and lung tissue pathological injury. CFE pre-Administration improved the survival rate of mice challenged with a lethal dose of LPS. CFE reduced LPS-Activated RAW264.7 cells to produce nitric oxide, TNF-α, MCP-1, and IL-6. Furthermore, CFE inhibited nuclear translocation and phosphorylation of NF-κB P65, extracellular signal-regulated kinase, c-Jun N-Terminal kinases, and P38 MAPKs. Conclusions: CFE exhibits potent anti-inflammatory activity in LPS-induced ALI mice, LPS-shock mice, and RAW264.7 cells, and its mechanism may be associated with the inhibition of NF-κB and MAPK signaling pathways. Crotalaria ferruginea may be a useful therapeutic drug for the treatment of ALI and other respiratory inflammations.

ABSTRACT

OBJECTIVE@#To investigate the incidence rate and risk factors for metabolic bone disease of prematurity (MBDP) in very low birth weight/extremely low birth weight (VLBW/ELBW) infants.@*METHODS@#The medical data of 61 786 neonates from multiple centers of China between September 1, 2013 and August 31, 2016 were retrospectively investigated, including 504 VLBW/ELBW preterm infants who met the inclusion criteria. Among the 504 infants, 108 infants diagnosed with MBDP were enrolled as the MBDP group and the remaining 396 infants were enrolled as the non-MBDP group. The two groups were compared in terms of general information of mothers and preterm infants, major diseases during hospitalization, nutritional support strategies, and other treatment conditions. The multivariate logistic regression analysis was used to investigate the risk factors for MBDP.@*RESULTS@#The incidence rate of MBDP was 19.4% (88/452) in VLBW preterm infants and 38.5% (20/52) in ELBW preterm infants. The incidence rate of MBDP was 21.7% in preterm infants with a gestational age of < 32 weeks and 45.5% in those with a gestational age of < 28 weeks. The univariate analysis showed that compared with the non-MBDP group, the MBDP group had significantly lower gestational age and birth weight, a significantly longer length of hospital stay, and a significantly higher incidence rate of extrauterine growth retardation (@*CONCLUSIONS@#A lower gestational age, hypocalcemia, extrauterine growth retardation at discharge, and neonatal sepsis may be associated an increased risk of MBDP in VLBW/ELBW preterm infants. It is necessary to strengthen perinatal healthcare, avoid premature delivery, improve the awareness of the prevention and treatment of MBDP among neonatal pediatricians, and adopt positive and reasonable nutrition strategies and comprehensive management measures for preterm infants.
