ABSTRACT

OBJECTIVE@#To explore the association between de novo mutations (DNM) and non-syndromic cleft lip with or without palate (NSCL/P) using case-parent trio design.@*METHODS@#Whole-exome sequencing was conducted for twenty-two NSCL/P trios and Genome Analysis ToolKit (GATK) was used to identify DNM by comparing the alleles of the cases and their parents. Information of predictable functions was annotated to the locus with SnpEff. Enrichment analysis for DNM was conducted to test the difference between the actual number and the expected number of DNM, and to explore whether there were genes with more DNM than expected. NSCL/P-related genes indicated by previous studies with solid evidence were selected by literature reviewing. Protein-protein interactions analysis was conducted among the genes with protein-altering DNM and NSCL/P-related genes. R package "denovolyzeR" was used for the enrichment analysis (Bonferroni correction: P=0.05/n, n is the number of genes in the whole genome range). Protein-protein interactions among genes with DNM and genes with solid evidence on the risk factors of NSCL/P were predicted depending on the information provided by STRING database.@*RESULTS@#A total of 339 908 SNPs were qualified for the subsequent analysis after quality control. The number of high confident DNM identified by GATK was 345. Among those DNM, forty-four DNM were missense mutations, one DNM was nonsense mutation, two DNM were splicing site mutations, twenty DNM were synonymous mutations and others were located in intron or intergenic regions. The results of enrichment analysis showed that the number of protein-altering DNM on the exome regions was larger than expected (P < 0.05), and five genes (KRTCAP2, HMCN2, ANKRD36C, ADGRL2 and DIPK2A) had more DNM than expected (P < 0.05/(2×19 618)). Protein-protein interaction analysis was conducted among forty-six genes with protein-altering DNM and thirteen genes associated with NSCL/P selected by literature reviewing. Six pairs of interactions occurred between the genes with DNM and known NSCL/P-related genes. The score measuring the confidence level of the predicted interaction between RGPD4 and SUMO1 was 0.868, which was higher than the scores for other pairs of genes.@*CONCLUSION@#Our study provided novel insights into the development of NSCL/P and demonstrated that functional analyses of genes carrying DNM were warranted to understand the genetic architecture of complex diseases.

ABSTRACT

ObjectiveTo establish an evaluation method for mitochondrial energy metabolism with Seahorse analyzer and investigate the protective effect of Yiqi Jiedu prescriptions (YQ) on mitochondria in rat adrenal pheochromocytoma (PC12) cells against hypoxia injury. MethodThe PC12 cell injury model was induced in vitro using hypoxic chambers. Five groups were set up, ie, a control group, a model group (model), high- (25 µmol·L-1), medium- (5 µmol·L-1) and low-dose (1 µmol·L-1) YQ groups, and a positive drug trimetazidine (TMZ) group, with three replicate wells in each group. The experiment was repeated three times. The established method for energy metabolism analysis was used to assay the activity of mitochondrial complex in cells and screen the optimal dosing concentration. Subsequently, the YQ group and modified YQ groups were set up, and the aerobic respiration and glycolysis function were assayed by the Seahorse analyzer. According to the non-mitochondrial oxygen consumption, proton leakage, basal respiration, maximum respiration, ATP production, and potentially improved respiration, the effects of modified YQ groups on the aerobic respiration of mitochondria damaged by hypoxia were evaluated by principal component analysis (PCA) and variable importance in projection (VIP). The expression of cytochrome C, B-cell lymphoma-2 (Bcl-2), and Bcl-2-associated X protein (Bax) was detected by Western blot. ResultCompared with the groups of other concentrations, the optimal dosing concentration of carbonyl cyanide-4 (trifluoromethoxy)phenylhydrazone (FCCP) was 2 µmol·L-1. Compared with the model group, the medium-dose YQ group showed enhanced mitochondrial complex activity (P<0.05). The YQ groups were superior to the model group in improvement (P<0.01). The combination of ginsenoside and geniposide showed the optimal effect among the modified YQ groups (P<0.01). VIP analysis revealed that for the improvement of mitochondrial respiratory function, the contribution of geniposide in YQ was the greatest. Compared with the model group, the high-dose YQ group displayed reduced leakage of mitochondrial cytochrome C (P<0.01), decreased expression of Bax protein (P<0.01), and increased expression of Bcl-2 protein (P<0.05, P<0.01). ConclusionA cellular, high-throughput quantitative evaluation method for mitochondrial energy metabolism was established, which demonstrated that YQ could significantly improve the impaired mitochondrial energy metabolism in PC12 cells damaged by hypoxia, and the underlying mechanism might be related to the protection against mitochondrial apoptosis.

ABSTRACT

ObjectiveTo investigate the effect and mechanism of Guilu Erxiangao on Alzheimer's disease (AD) model rats induced by hydrocortisone and amyloid β-protein(Aβ) based on the theory of kidney-brain correlation. MethodIntraperitoneal injection of hydrocortisone and intracerebroventricular injection of Aβ were performed to induce AD in rats, and different concentrations of Guilu Erxiangao were used for intervention. The indexes of hippocampus, kidney and adrenal gland were measured, and the spatial learning and memory ability of AD rats was observed by Morris water maze experiment. The levels of testosterone (T) and corticosterone (CORT) in serum samples were determined by enzyme-linked immunosorbent assay (ELISA). Liquid chromatography-mass spectrometry (LC-MS) was used to collect and analyze the serum metabolic data of model rats. The active components and corresponding targets of Guilu Erxiangao were collected using Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP), a Bioinformatics Analysis Tool for Molecular mechANism of Traditional Chinese Medicine (BATMAN-TCM) and Traditional Chinese Medicine Integrated Database(TCMID). GeneCards and Online Mendelian Inheritance in Man (OMIM) were retrieved to obtain AD-related targets, and protein-protein interaction (PPI) network was constructed to perform gene ontology (GO)and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. The expression level of interleukin-6 (IL-6) in the hippocampus of rats was detected by Western blot. ResultCompared with the model group, the low-, medium- and high-dose groups of Guilu Erxiangao exhibited significantly increased hippocampus index, kidney index and adrenal gland index, reduced CORT levels in serum and down-regulated IL-6 levels in hippocampal tissues. According to the results of water maze experiment, as compared with the model group, the platform crossing times of rats was significantly increased in the low- and high-dose groups of Guilu Erxiangao, with evidently prolonged distance traveled in quadrant Ⅲ (%) and time in quadrant Ⅲ (%). A total of 24 serum differential metabolites associated with AD were identified by LC-MS, and 50 high-frequency common compounds and 187 high-frequency common targets for AD treatment were screened by network pharmacology method. Results demonstrated phosphatidylinositol 3-kinases(PI3K)/protein kinase B(Akt) signaling pathway plays an important role in the complex AD pathological mechanism. ConclusionGuilu Erxiangao can significantly improve the cognitive dysfunction of AD model rats induced by hydrocortisone and Aβ, reduce serum CORT levels and IL-6 levels in hippocampal tissues, and regulate the metabolic level, which provides a reference for its clinical application.

ABSTRACT

Echinococcosis is mainly prevalent in the agricultural and pastoral areas in the northwest of China, but it is relatively rare in Hunan Province. Here, we reported the clinical data of a case of echinococcosis in Hunan Province. The patient was an 11-year-old male, who sought treatment at the Second Xiangya Hospital of Central South University due to abdominal mass. According to the symptoms, signs, and laboratory examinations, he was initially diagnosed as "intra-abdominal mass" and "spleen cyst". Subsequently, he underwent abdominal massive occupying resection and splenectomy. Postoperative pathological examination revealed the cuticle and germinal layer of hydatid and protoscolex, which was consistent with characteristics of echinococcosis. In addition, the serological examination showed that the specific anti-hydatid IgG antibody was positive. Combined with the patient's condition, he was given praziquantel treatment. After a month of follow-up, the patient was asymptomatic.

ABSTRACT

Objective@#We investigated changes in the intestinal flora of children with Mycoplasma pneumoniae pneumonia (MPP).@*Methods@#Between September 2019 and November 2019, stool samples from 14 children with MPP from The Fourth Hospital of Baotou city, Inner Mongolia Autonomous Region, were collected and divided into general treatment (AF) and probiotic (AFY) groups, according to the treatment of "combined Bifidobacterium, Lactobacillus, Enterococcus, and Bacillus cereus tablets live". High-throughput 16S rDNA sequencing was used to identify intestinal flora.@*Results@#Intestinal flora abundance and diversity in children with MPP were decreased. Both Shannon and Simpson indices were lower in the AF group when compared with healthy controls ( P < 0.05). When compared with healthy controls, the proportion of Enterorhabdus was lower in the AF group, while the proportion of Lachnoclostridium was higher ( P < 0.05). The proportion of Bifidobacteria and Akkermansia was lower in the AFY group but Enterococcus, Lachnoclostridium, Roseburia, and Erysipelatoclostridium proportions were higher. The proportion of Escherichia coli- Shigella in the AFY group after treatment was decreased ( P < 0.05).@*Conclusions@#The intestinal flora of children with MPP is disturbed, manifested as decreased abundance and diversity, and decreased Bifidobacteria. Our probiotic mixture partly improved intestinal flora disorders.

ABSTRACT

OBJECTIVE@#To compare the clinical efficacy and its effect on serum levels of tumor necrosis factor α(TNF-α), interleukin 1β(IL-1β), interleukin 6 (IL-6) and prostaglandin E2 (PGE2) between short needling (close-to-bone needling) and conventional acupuncture for knee osteoarthritis (KOA) with blood stasis obstruction.@*METHODS@#A total of 68 KOA patients with blood stasis obstruction were randomized into a short needling group (34 cases, 3 cases dropped off) and a conventional acupuncture group (34 cases, 3 cases dropped off). The same acupoints (Dubi [ST 35], Neixiyan [EX-LE 4], Binzhong [Extra], Liangqiu [ST 34], etc. on the affected side) were selected in the two groups. In the short needling group, short needling technique was adopted, the needles were slowly inserted and the needle bodies were shaken, thus gradually penetrated to the bone. In the conventional acupuncture group, conventional acupuncture was adopted, the needles were penetrated to the muscle. After qi-arrival, Dubi (ST 35) and Neixiyan (EX-LE 4), Zusanli (ST 36) and Liangqiu (ST 34) were connected with CMNS6-1 electronic acupuncture instrument, with disperse-dense wave, 2 Hz/10 Hz in frequency, the current intensity was based on patients' feeling, the needles were retained for 30 min, at the same time, the knee joint was irradiated for 30 min with a special electromagnetic wave apparatus in the two groups. Once every other day, 3 times a week for 4 weeks. Before and after treatment, the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) score, knee joint pain visual analogue scale (VAS) score, inflammatory response related indexes (serum TNF-a, IL-1β, IL-6 and PGE2) and knee joint ultrasound were observed,and the clinical effect was evaluated in the two groups.@*RESULTS@#After treatment,the pain, stiffness, function scores and total scores of WOMAC were decreased as compared with those before treatment in the two groups (P<0.05), except for the pain score, the changes of above scores in the short needling group were greater than the conventional acupuncture group (P<0.05). After treatment, the VAS scores, serum levels of TNF-a, IL-1β, IL-6, PGE2 and knee joint synovium thickness, intra-articular effusion were decreased as compared with those before treatment in the two groups (P<0.05), the levels of TNF-a, IL-1β, IL-6 in the short needling group were lower than the conventional acupuncture group (P<0.05). The total effective rate in the short needling group was 87.1% (27/31), which was superior to 83.9% (26/31) in the conventional acupuncture group (P<0.05).@*CONCLUSION@#Short needling could improve the knee joint function, relieve the pain and inflammatory response, improve the knee joint synovium inflammatory response, reduce the knee joint intra-articular effusion for KOA patients, its effect is better than conventional acupuncture.

ABSTRACT

Objective: To analyze the clinical characteristics, treatment and prognosis of Hashimoto's encephalopathy presenting with isolated cerebellar ataxia in children. Methods: A retrospective analysis was performed on the clinical features, laboratory tests, neuroelectrophysiological examination, imaging, treatment and outcomes of 13 patients with Hashimoto's encephalopathy presenting with isolated cerebellar ataxia, who were admitted to the Department of Pediatric Neurology of Guangzhou Women and Children's Medical Center from January 2016 to May 2021. Results: Among the 13 cases, 6 were males and 7 were females. The onset age was 2.6 (2.0,3.3) years, 9 children had precursor infection or vaccination before the first course of disease. All the 13 children had gait abnormalities or unsteady sitting, 10 had intentional tremor, 6 had dysarthria, 3 had body tremor, 2 had nystagmus, 3 had fatigue, 3 had hypotonia, 2 had vomiting and 1 had irritability. Thyroglobulin antibody (TgAb) was 500.0 (298.9,587.2) kU/L and thyroid peroxidase antibody (TPOAb) was 621.9 (449.6,869.4) kU/L in 13 cases. Autoantibodies were positive in 9 cases, and cerebrospinal fluid leukocytosis was seen in 4 cases. Regarding electroencephalography result, 4 cases had background slowing and 1 case had occasional sharp waves. Among the 3 patients who had relapses, 1 had cerebellar atrophy shown on cranial magnetic resonance imaging (MRI) during the recurrence. All the patients received intravenous immunoglobulin (IVIG) and intensive methylprednisolone therapy during the first onset, followed by the disappearance of the symptoms, 1 patient had repeated episodes which was decreased after immunosuppressive treatment with Rituximab.Followed up for 25.0 (22.5,33.3) months after the last episode, 12 achieved complete remission and 1 had a wide base gait. Conclusions: Trunk ataxia is the common symptom of Hashimoto's encephalopathy presenting with isolated cerebellar ataxia in children.Children with cerebellar ataxia should be tested for TgAb and TPOAb to detect Hashimoto's encephalopathy, avoiding missed diagnosis and treatment delays; IVIG and intensive steroid therapy is effective, and immunosuppressive therapy for patients with multiple relapses could reduce the recurrence.

ABSTRACT

Objective: To assess the association between short-term exposure level of nitrogen dioxide and the hospitalization risk of heart failure. Methods: Based on China-PEACE Retrospective Heart Failure Study, 117 364 hospitalized patients with heart failure were recruited from 92 hospitals in 62 cities throughout China between January 1, 2015 and December 31, 2015. The daily exposure level of nitrogen dioxide, temperature, and humidity in the same cities during the same period were also collected. We applied the generalized additive model and Bayesian hierarchical model to quantify the lagged effect and cumulative effect of short-term (0-3 days) exposure to ambient nitrogen dioxide on the hospitalization risk of heart failure. We further conducted stratified analyses by age, region, and season to identify any difference in the associations between short-term nitrogen dioxide exposure and heart failure among subgroups. Results: The mean age for participants in the analysis was (70.32±12.22) years. The median, minimum and maximum of daily nitrogen dioxide concentration in 62 cities from January 1, 2015 to December 31, 2015 was 26.4 μg/m3, 2.33 μg/m3 and 150.25 μg/m3, respectively. The exposure level of nitrogen dioxide at the same day was associated with the hospitalization risk of heart failure (OR=1.022, 95%CI: 1.012, 1.031). Significant effects were also observed in the moving average concentrations from lag 0-1 to lag 0-3 day (OR=1.020, 95%CI: 1.009, 1.030; OR=1.016, 95%CI: 1.004, 1.028; OR=1.013, 95%CI: 1.001, 1.026). Moreover, all of the associations between short-term exposure to nitrogen dioxide and the risk of heart failure hospitalization were statistically significant, with no significant difference in all subgroups stratified by age, region, and season. Conclusion: A higher level of short-term exposure to nitrogen dioxide could trigger more hospitalizations with heart failure.

ABSTRACT

Youth is the core force of social and economic development, once the occurrence of youth stroke will place a heavy burden on society and family. However, the prevention and control of stroke in China is mainly aimed at middle-aged and elderly patients, the part of young stroke is relatively easy to be ignored. This article focuses on the characteristics, research progress, prevention and control status of young stroke, pointing out the importance of centering on the prevention and treatment of young stroke. At the same time, it hopes that the industry can concentrate on the prevention and treatment of young stroke, making precise policies in the future, and developing secondary prevention guidelines for the causes or risk factors of young stroke, so as to improve comprehensive stroke prevention and control system. On this basis, the health level of the whole population will be improved, and the life expectancy of residents will be extended, thus promoting the realization of the strategic goal of "Healthy China 2030".

ABSTRACT

Objective: To investigate the representability and etiological diagnostic value of myocardium samples obtained from patients with hypertrophic cardiomyopathy (HCM) by transthoracic echocardiography-guided percutaneous intramyocardial septal biopsy (myocardial biopsy of Liwen procedure). Methods: This study was a retrospective case-series analysis. Patients with HCM, who underwent myocardial biopsy of Liwen procedure and radiofrequency ablation in Xijing Hospital, Air Force Military Medical University from July to December 2019, were included. Demographic data (age, sex), echocardiographic data and complications were collected through electronic medical record system. The histological and echocardiographic features, pathological characteristics of the biopsied myocardium of the patients were analyzed. Results: A total of 21 patients (aged (51.2±14.5) years and 13 males (61.9%)) were enrolled. The thickness of ventricular septum was (23.3±4.5)mm and the left ventricular outflow tract gradient was (78.8±42.6)mmHg (1 mmHg=0.133 kPa). Eight patients (38.1%) were complicated with hypertension, 1 patient (4.8%) had diabetes, and 2 patients (9.5%) had atrial fibrillation. Hematoxylin-eosin staining of myocardial samples of HCM patients before radiofrequency ablation evidenced myocytes hypertrophy, myocytes disarray, nuclear hyperchromatism, hypertrophy, atypia, coronary microvessel abnormalities, adipocyte infiltration, inflammatory cell infiltration, cytoplasmic vacuoles, lipofuscin deposition. Interstitial fibrosis and replacement fibrosis were detected in Masson stained biopsy samples. Hematoxylin-eosin staining of myocardial samples of HCM patients after radiofrequency ablation showed significantly reduced myocytes, cracked nuclear in myocytes, coagulative necrosis, border disappearance and nuclear fragmentation. Quantitative analysis of myocardial specimens of HCM patients before radiofrequency ablation showed that there were 9 cases (42.9%) with mild myocardial hypertrophy and 12 cases (57.1%) with severe myocardial hypertrophy. Mild, moderate and severe fibrosis were 5 (23.8%), 9 (42.9%) and 7 (33.3%), respectively. Six cases (28.6%) had myocytes disarray. There were 11 cases (52.4%) of coronary microvessel abnormalities, 4 cases (19.0%) of adipocyte infiltration, 2 cases (9.5%) of inflammatory cell infiltration,6 cases (28.5%) of cytoplasmic vacuole, 16 cases (76.2%) of lipofuscin deposition. The diameter of cardiac myocytes was (25.2±2.8)μm, and the percentage of collagen fiber area was 5.2%(3.0%, 14.6%). One patient had severe replacement fibrosis in the myocardium, with a fibrotic area of 67.0%. The rest of the patients had interstitial fibrosis. The myocardial specimens of 13 patients were examined by transmission electron microscopy. All showed increased myofibrils, and 9 cases had disorder of myofibrils. All patients had irregular shape of myocardial nucleus, partial depression, mild mitochondrial swelling, fracture and reduction of mitochondrial crest, and local aggregation of myofibrillary interfascicles. One patient had hypertrophy of cardiomyocytes, but the arrangement of muscle fibers was roughly normal. There were vacuoles in the cytoplasm, and Periodic acid-Schiff staining was positive. Transmission electron microscopy showed large range of glycogen deposition in the cytoplasm, with occasional double membrane surround, which was highly indicative of glycogen storage disease. No deposition of glycolipid substance in lysozyme was observed under transmission electron microscope in all myocardial specimens, which could basically eliminate Fabry disease. No apple green substance was found under polarized light after Congo red staining, which could basically exclude cardiac amyloidosis. Conclusion: Myocardium biopsied samples obtained by Liwen procedure of HCM patients are representative and helpful for the etiological diagnosis of HCM.

ABSTRACT

Objective: To investigate the functional changes of key gut microbiota (GM) that produce lipopolysaccharide (LPS) in atrial fibrillation (AF) patients and to explore their potential role in the pathogenesis of AF. Methods: This was a prospective cross-sectional study. Patients with AF admitted to Beijing Chaoyang Hospital of Capital Medical University were enrolled from March 2016 to December 2018. Subjects with matched genetic backgrounds undergoing physical examination during the same period were selected as controls. Clinical baseline data and fecal samples were collected. Bacterial DNA was extracted and metagenomic sequencing was performed by using Illumina Novaseq. Based on metagenomic data, the relative abundances of KEGG Orthology (KO), enzymatic genes and species that harbored enzymatic genes were acquired. The key features were selected via the least absolute shrinkage and selection operator (LASSO) analysis. The role of GM-derived LPS biosynthetic feature in the development of AF was assessed by receiver operating characteristic (ROC) curve, partial least squares structural equation modeling (PLS-SEM) and logistic regression analysis. Results: Fifty nonvalvular AF patients (mean age: 66.0 (57.0, 71.3), 32 males(64%)) were enrolled as AF group. Fifty individuals (mean age 55.0 (50.5, 57.5), 41 males(82%)) were recruited as controls. Compared with the controls, AF patients showed a marked difference in the GM genes underlying LPS-biosynthesis, including 20 potential LPS-synthesis KO, 7 LPS-biosynthesis enzymatic genes and 89 species that were assigned as taxa harbored nine LPS-enzymatic genes. LASSO regression analysis showed that 5 KO, 3 enzymatic genes and 9 species could be selected to construct the KO, enzyme and species scoring system. Genes enriched in AF group included 2 KO (K02851 and K00972), 3 enzymatic genes (LpxH, LpxC and LpxK) and 7 species (Intestinibacter bartlettii、Ruminococcus sp. JC304、Coprococcus catus、uncultured Eubacterium sp.、Eubacterium sp. CAG:251、Anaerostipes hadrus、Dorea longicatena). ROC curve analysis revealed the predictive capacity of differential GM-derived LPS signatures to distinguish AF patients in terms of above KO, enzymatic and species scores: area under curve (AUC)=0.957, 95%CI: 0.918-0.995, AUC=0.940, 95%CI 0.889-0.991, AUC=0.972, 95%CI 0.948-0.997. PLS-SEM showed that changes in lipopolysaccharide-producing bacteria could be involved in the pathogenesis of AF. The key KO mediated 35.17% of the total effect of key bacteria on AF. After incorporating the clinical factors of AF, the KO score was positively associated with the significantly increased risk of AF (OR<0.001, 95%CI:<0.001-0.021, P<0.001). Conclusion: Microbes involved in LPS synthesis are enriched in the gut of AF patients, accompanied with up-regulated LPS synthesis function by encoding the LPS-enzymatic biosynthesis gene.

ABSTRACT

Objective To explore the correlation between dose, blood concentration and efficacy of voriconazole in the treatment of invasive fungal infection in children. Methods 68 children treated with voriconazole during January 2019 to December 2019 were collected. The plasma concentration of voriconazole was assayed by high performance liquid chromatography (HPLC). The correlation between blood concentration and clinical efficacy was statistically analyzed. Results Different drug blood concentrations were obtained with different dosages: <4.0 mg/kg (6 cases) with the trough concentration ranged from 0.4 to 3.31 μg/ml (r=0.613, P=0.195). (4.0 - 7.0) mg/kg (44 cases), ranged from 0.35 to 7.02 μg/ml (r=0.325, P=0.018); >7.0 mg/kg (18 cases), ranged from 1.46 to 12.45 μg/ml (r=0.584,P<0.023). There was a difference between the three groups (F=7.270, P=0.026). The relationship between the drug blood concentration and the therapeutic effect was obvious. In the <1.0 μg/ml group of 14 cases, 10 cases (71.4%) were effective, and 4 cases were ineffective. In the 1.0 - 5.5 μg/ml group of 48 cases, 44 cases (91.7%) were effective, and 4 cases were ineffective. In the >5.5 μg/ml group of 6 cases, 4 cases (66.7%) were effective and 2 cases ineffective. The difference among the three groups was obvious (χ2=5.360, P=0.039). Among the 68 cases, 58 cases (85.3%) were effective, and 10 cases (14.7%) were ineffective. Adverse reactions occurred in 10 cases (14.7%) with mild liver function injury, which did not affect the treatment and recovered with liver protection treatment. Conclusion This study showed that voriconazole was generally safe and effective in the treatment of invasive fungal infections in children. There was a significant dose-blood concentration and efficacy correlation. Further studies on pharmacokinetics and efficacy should be carried out to optimize the individualized treatment.

ABSTRACT

AIM:To discuss the efficacy and safety of orthokeratology with reducing back optic zone diameter(5mm-BOZD)compared with conventional back optic zone diameter(6mm-BOZD)in the treatment of adolescent myopia.METHODS: A prospective randomized controlled trial was performed. There were 100 cases with 100 eyes of adolescent myopia(all right eye data were taken)selected from April 2016 to January 2019, the spherical degree was -1.00--5.00D. Then they were randomly divided into the two groups. The experimental group wore 5mm-BOZD orthokeratology, and the control group wore 6mm-BOZD orthokeratology. Their axis length(AL), spherical equivalent(SE), relative peripheral refraction(RPR), best corrected visual acuity(BCVA), uncorrected near visual acuity(NVA), Efron grading was applied to record the anterior segment of the eyes, corneal hysteresis(CH), corneal resistance factor(CRF), corneal-compensated intraocular pressure(IOPcc), average noninvasive Keratograph tear breakup time(NIKBUTav)and higher order aberration(RMSh) were compared between the two groups during the 1a treatment period.RESULTS: After 1a of treatment, the AL in experimental group increased 0.05±0.05mm,while it increased 0.15±0.05mm(t=-8.949, P<0.001)in control group. The SE in experimental group increased -0.18±0.27D,while it increased-0.42±0.35D(t=3.609, P=0.001)in control group. There were statistical differences in RPR changes at N30°, N20° and T30°sites between the two groups(P<0.05). There were no statistical differences in BCVA,NVA,Efron grade,CH,CRF,IOPcc,NIKBUTav and RMSh between the two groups(P>0.05).CONCLUSION:Reducing back optic zone diameter orthokeratology can correct adolescent myopia safely and more effectively during the observation period.

ABSTRACT

Objective@#To understand the status quo and influencing factors of overweight and obesity in preschool children, and to provide scientific theoretical reference for the prevention and control of overweight and obesity in preschool children in Urumqi.@*Methods@#Stratified cluster sampling method was adopted to select 1 897 preschool children from 10 kindergartens in Urumqi from October to December in 2021 to understand the status quo of overweight and obesity of preschool children by measuring their height and weight. The influencing factors were collected by questionnaire survey, including Chinese preschoolers eating behavior questionnaire, Chinese preschooler s caregivers feeding behavior scale, 3-6 year old children s home nurture environment scale, and characteristics and influencing factors of physical activity among preschool children.@*Results@#The prevalence of overweight and obesity in preschool children was 31.21% (592), including 19.50% (370) overweight and 11.70% (222) obesity.Childhood overweight and obesity detection rates varied significantly by age, sex, child dietary habits, father BMI, maternal BMI, and maternal pre pregnancy BMI ( χ 2=19.63,28.75,9.45,18.21,18.45,19.36, P <0.05). Multivariate Logistic regression analysis showed that gender, children s eating habits, paternal BMI, pregnancy BMI, satiety responsiveness, external eating, initiative eating, weight concerns, behavior restricted feeding, physical activity and family physical activity environment were the influencing factors of overweight and obesity in preschool children( OR =0.52,1.43,1.51,1.44,0.69,0.74,1.35,1.71,0.81,0.96,1.10, P < 0.05 ).@*Conclusion@#Overweight and obesity in preschool children are popular in Urumqi. Education, diet control and scientific exercise should be strengthened to prevent childhood overweight and obesity.

ABSTRACT

Objective@#To explore the association between circadian rhythm with depressive and anxiety symptoms of college students in Jinzhou City, to provide a theoretical basis for targeted depression and anxiety prevention among college students.@*Methods@#A total of 1 938 college students were selected by convenient sampling method from November to December 2020 for questionnaire survey. The relationship between circadian rhythm and depression and anxiety symptoms was analyzed by using questionnaire,survey including Self Rating Depression Scale (SDS), Self Rating Anxiety Scale (SAS) and Munich Chronotype Questionnaire (MCTQ).@*Results@#There were significant differences in the distribution of depressive symptoms in different majors, smoking, drinking and physical exercise ( χ 2=46.80, 5.88, 5.76, 12.23, P <0.05). There were significant differences in the distribution of anxiety symptoms in different majors, smoking and drinking ( χ 2=9.41, 5.80, 5.56, P <0.05). Stratified analysis showed that the depressive symptoms of different chronotype were statistically varied by age, gender, professional, grade, registered residence, body mass index, smoking, drinking, and sports( χ 2=8.16, 14.42, 12.25, 6.19, 10.99, 15.29, 17.41, 15.63, 7.47, 9.59, 10.51 , P <0.05). The anxiety symptoms of different chronotype were statistically different in age (21 years) and smoking (no), ( χ 2= 8.34 , 7.16, P <0.05). Spearman rank correlation showed that the corrected Mid sleep on Free Days Corrected for Sleep Debt on Work Days (MSFsc) was positively correlated with the standard scores of depression and anxiety ( r s=0.10, 0.09), and social jet lag was positively correlated with the standard scores of depression and anxiety ( r s=0.09, 0.05)( P <0.05). After controlling for age, major, smoking and drinking, binary Logistic regression showed that mean sleep length was inversely correlated with depressive symptoms ( OR =0.82), and weekly insomnia frequency was positively correlated with depressive symptoms ( OR=1.14 ).Early type and intermediate type of chronotypes were negatively correlated with depression ( OR =0.66,0.57). Intermediate type of chronotype was negatively correlated with anxiety symptoms ( OR =0.65).@*Conclusion@#Circadian rhythm is related to depressive and anxiety symptoms,among which the average sleep length, early rise and intermediate sleep patterns are negatively related to depression symptoms, and intermediate sleep patterns and anxiety symptoms, suggesting that circadian rhythm disorder may affect depression and anxiety symptoms.

ABSTRACT

Objective:To detect the serum levels of SARS-CoV-2-specific IgM and IgG antibodies in patients infected with SARS-CoV-2 and recipients of inactivated vaccine in different periods for understanding their variation patterns in vivo. Methods:Chemiluminescence immunoassay was used to detect the levels of SARS-CoV-2-specific IgM and IgG antibodies in 144 serum samples of 44 COVID-19 patients, 381 serum samples of 118 asymptomatic infected cases and 398 serum samples of 273 inactivated vaccine recipients collected at different periods. The results were statistically analyzed together with basic characteristics and vaccination status.Results:The positive rates of IgM antibody in COVID-19 patients, asymptomatic infected cases and inactivated vaccine recipients were 52.27% (23/44), 23.73% (28/118) and 14.29% (39/273). The positive rate of IgM antibody was higher in COVID-19 patients than in asymptomatic infected cases and vaccine recipients (χ 2=12.106, P=0.001; χ 2=34.755, P<0.001). The positive rates of IgG antibody in the three populations were 100.00% (44/44), 97.46% (115/118) and 98.81% (166/168), and the differences were not statistically significant (χ 2=2.944, P=0.229). In COVID-19 patients, the concentration of IgM antibody in <40 years old group was lower than that in ≥40 years old group (Waldχ 2=6.609, P=0.010), and the concentration of IgG antibody in patients with vaccination was higher than that in patients without vaccination (Waldχ 2=12.402, P<0.001). In asymptomatic infected cases, the concentration of IgG antibody was higher in people with vaccination than in those without vaccination (Waldχ 2=4.530, P=0.033). In SARS-CoV-2 vaccine recipients, the concentration of IgG antibody in <40 years old group was higher than that in ≥40 years old group (Waldχ 2=9.565, P=0.002). Dynamic analysis of antibody levels showed that from week 1 to week 9, the concentrations of IgM and IgG antibodies in COVID-19 patients were higher than those in asymptomatic infected cases and vaccine recipients. Conclusions:The concentrations of IgM and IgG antibodies in COVID-19 patients were higher than those in asymptomatic infected cases and inactivated vaccine recipients. COVID-19 patients aged ≥40 years had higher level of IgM antibody. COVID-19 patients and asymptomatic infected cases who had received vaccination had higher concentration of IgG antibody. Inactivated vaccine showed good immunogenicity after whole course of immunization, and the IgG antibody level in <40 years old group was higher.

ABSTRACT

Objective:To investigate the level of intrinsic capacity in community-dwelling elderly people and the influencing factors, in order to provide supporting evidence for the improvement of intrinsic capacity, formulation of management strategies, and promotion of quality of life for the elderly.Methods:A cross-sectional survey was carried out from November 2020 to December 2020 with 236 community-dwelling elderly people in Beijing, who were recruited through a convenience sampling method.The investigation used questionnaires for general data and influencing factors for intrinsic capacity, and the World Health Organization intrinsic capacity questionnaire.Multivariate logistic regression was used to analyze the influencing factors for intrinsic capacity of the elderly.Results:Among 236 community-dwelling elderly people, 132(55.9%)had fair intrinsic capacity(≥4 points)and 104(44.1%)had poor intrinsic capacity(<4 points), with an average score of(3.39±0.95). Multiple Logistic regression analysis results showed that sex( OR=2.005, 95% CI: 1.093-3.676, P=0.025), age( OR=1.727, 95% CI: 1.043-2.860, P=0.034), social participation( OR=0.321, 95% CI: 0.170-0.604, P<0.001), entertainment( OR=2.073, 95% CI: 1.079-3.985, P=0.029), exercise( OR=2.975, 95% CI: 1.761-3.784, P=0.039), sleep( OR=0.508, 95% CI: 0.265-0.973, P=0.041), and emotions( OR=0.436, 95% CI: 0.196-0.970, P=0.042)were influencing factors for intrinsic capacity of community-dwelling elderly people. Conclusions:The intrinsic capacity of community-dwelling elderly people is in the middle range.Sex, age, social participation, entertainment, exercise, sleep, and emotions can affect intrinsic capacity.Therefore, intervention strategies based on influencing factors and improvement of lifestyles can help maintain good intrinsic capacity and reduce adverse effects of major health events.
