ABSTRACT

OBJECTIVE@#To explore the clinical phenotype and genetic characteristics of a fetus with 17q12 microdeletion syndrome.@*METHODS@#A fetus with 17q12 microdeletion syndrome who was diagnosed at Huzhou Maternal & Child Health Care Hospital in June 2020 was selected as the study subject. Clinical data of the fetus was collected. The fetus was subjected to chromosomal karyotyping and chromosomal microarray analysis (CMA). To determine the origin of fetal chromosomal abnormality, its parents were also subjected to CMA assay. The postnatal phenotype of the fetus was also investigated.@*RESULTS@#Prenatal ultrasound revealed polyhydramnios and fetal renal dysplasia. The fetus was found to have a normal chromosomal karyotype. CMA has detected a 1.9 Mb deletion in the 17q12 region, which has encompassed five OMIM genes including HNF1B, ACACA, ZNHIT3, CCL3L1 and PIGW. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the 17q12 microdeletion was predicted as pathogenic copy number variation (CNV). CMA analysis has detected no pathogenic CNV in both parents. After birth, the child was found to have renal cysts and abnormal brain structure. Combined with the prenatal findings, the child was diagnosed with 17q12 microdeletion syndrome.@*CONCLUSION@#The fetus has 17q12 microdeletion syndrome presenting as abnormalities of the kidney and central nervous system, which are strongly correlated with functional defects of the deletion region involving the HNF1B and other pathogenic genes.

ABSTRACT

Objective: To characterize the serum bile acid profiles of healthy children in Zhejiang Province. Methods: A cross-sectional study was conducted on 245 healthy children who underwent imaging and laboratory biochemical tests during routine physical examinations at the Children's Hospital of Zhejiang University School of Medicine from January 2020 to July 2022. Overnight fasting venous blood samples were collected, and the concentrations of 18 individual bile acids in the serum were accurately quantitated using tandem mass spectrometry. The concentration difference of bile acid were compared between different genders and to explore the correlation between age and bile acid levels. Used the Mann-Whitney U test for intergroup comparison and Spearman test to correlation analysis. Results: A total of 245 health children with a age of 10 (8, 12) years including 125 boys and 120 girls. There were no significant differences in levels of total bile acids, primary and secondary bile acids, free and conjugated bile acids between the two gender groups (all P>0.05). The serum concentrations of ursodeoxycholic acid and glycoursodeoxycholic acid in girls were significantly higher than those in boys (199.0 (66.9, 276.5) vs. 154.7 (49.3, 205.0) nmol/L, 274.0 (64.8, 308.0) vs. 181.0 (43.8, 209.3) nmol/L, Z=2.06, 2.71, both P<0.05). The serum taurolithocholic acid in both boys and girls were positively correlated with age (r=0.31, 0.32, both P<0.05). The serum chenodeoxycholic acid and glycochenodeoxycholic acid in the boys group were positively correlated with age (r=0.20, 0.23, both P<0.05), whereas the serum tauroursodeoxycholic acid in the girls group was negatively correlated with age (r=-0.27, P<0.05), and the serum cholic acid was positively correlated with age (r=0.34, P<0.05). Conclusions: The total bile acid levels are relatively stable in healthy children in Zhejiang province. However, individual bile acids showed gender differences and were correlated with age.

ABSTRACT

Objective: To investigate the diagnostic efficiency and clinical application value of an artificial intelligence-assisted diagnosis model based on a three-dimensional convolutional neural network (3D CNN) on echocardiographic videos of patients with hypertensive heart disease, chronic renal failure (CRF) and hypothyroidism with cardiac involvement. Methods: This study is a retrospective study. The patients with hypertensive heart disease, CRF and hypothyroidism with cardiac involvement, who admitted in Henan Provincial People's Hospital from April 2019 to October 2021, were enrolled. Patients were divided into hypertension group, CRF group, and hypothyroidism group. Additionally, a simple random sampling method was used to select control healthy individuals, who underwent physical examination at the same period. The echocardiographic video data of enrolled participants were analyzed. The video data in each group was divided into a training set and an independent testing set in a ratio of 5 to 1. The temporal and spatial characteristics of videos were extracted using an inflated 3D convolutional network (I3D). The artificial intelligence assisted diagnosis model was trained and tested. There was no case overlapped between the training and validation sets. A model was established according to cases or videos based on video data from 3 different views (single apical four chamber (A4C) view, single parasternal left ventricular long-axis (PLAX) view and all views). The statistical analysis of diagnostic performance was completed to calculate sensitivity, specificity and area under the ROC curve (AUC). The time required for the artificial intelligence and ultrasound physicians to process cases was compared. Results: A total of 730 subjects aged (41.9±12.7) years were enrolled, including 362 males (49.6%), and 17 703 videos were collected. There were 212 cases in the hypertensive group, 210 cases in the CRF group, 105 cases in the hypothyroidism group, and 203 cases in the normal control group. The diagnostic performance of the model predicted by cases based on single PLAX view and all views data was excellent: (1) in the hypertensive group, the sensitivity, specificity and AUC of models based on all views data were 97%, 89% and 0.93, respectively, while those of models based on a single PLAX view were 94%, 95%, and 0.94, respectively; (2) in the CRF group, the sensitivity, specificity and AUC of models based on all views data were 97%, 95% and 0.96, respectively, while those of models based on a single PLAX view were 97%, 89%, and 0.93, respectively; (3) in the hypothyroidism group, the sensitivity, specificity and AUC of models based on all views data were 64%, 100% and 0.82, respectively, while those of models based on a single PLAX view were 82%, 89%, and 0.86, respectively. The time required for the 3D CNN model to measure and analyze the echocardiographic videos of each subject was significantly shorter than that for the ultrasound physicians ((23.96±6.65)s vs. (958.25±266.17)s, P<0.001). Conclusions: The artificial intelligence assisted diagnosis model based on 3D CNN can extract the dynamic temporal and spatial characteristics of echocardiographic videos jointly, and quickly and efficiently identify hypertensive heart disease and cardiac changes caused by CRF and hypothyroidism.

ABSTRACT

OBJECTIVE@#To explore the clinical and molecular characteristics of a child with Congenital disorders of glycosylation (CDG).@*METHODS@#A 4-month-old boy who had presented at the Children's Hospital Affiliated to Zhejiang University Medical School on December 31, 2019 due to feeding difficulties after birth was selected as the study subject. High-throughput sequencing was carried out for the patient, and real-time qPCR was used for validating the suspected deletion fragments and the carrier status of other members of his family.@*RESULTS@#High-throughput sequencing revealed that the child had lost the capture signal for chrX: 153 045 645-153 095 809 (approximately 50 kb), which has involved 4 OMIM genes including SRPK3, IDH3G, SSR4 and PDZD4. qPCR verified that the copy number in this region was zero, while that of his elder brother and parents was all normal.@*CONCLUSION@#The deletion of the fragment containing the SSR4 gene in the Xq28 region probably underlay the SSR4-CDG in this child.

ABSTRACT

Through bioinformatics predictions, we identified that GTF2I and FAT1 were downregulated in thyroid carcinoma (TC). Further, Pearson's correlation coefficient revealed a positive correlation between GTF2I expression and FAT1 expression. Therefore, we selected them for this present study, where the effects of bone marrow mesenchymal stem cell-derived EVs (BMSDs-EVs) enriched with GTF2I were evaluated on the epithelial-to-mesenchymal transition (EMT) and stemness maintenance in TC. The under-expression of GTF2I and FAT1 was validated in TC cell lines. Ectopically expressed GTF2I and FAT1 were found to augment malignant phenotypes of TC cells, EMT, and stemness maintenance. Mechanistic studies revealed that GTF2I bound to the promoter region of FAT1 and consequently upregulated its expression. MSC-EVs could shuttle GTF2I into TPC-1 cells, where GTF2I inhibited TC malignant phenotypes, EMT, and stemness maintenance by increasing the expression of FAT1 and facilitating the FAT1-mediated CDK4/FOXM1 downregulation. In vivo experiments confirmed that silencing of GTF2I accelerated tumor growth in nude mice. Taken together, our work suggests that GTF2I transferred by MSC-EVs confer antioncogenic effects through the FAT1/CDK4/FOXM1 axis and may be used as a promising biomarker for TC treatment.

ABSTRACT

Objective:To investigate the effect of ulinastatin injection on left ventricular diastolic function and prognosis in patients with sepsis.Methods:A total of 100 patients with sepsis admitted to the Intensive Care Unit from January 2021 to March 2022 were selected. According to the random number table, they were randomly (random number) divided into the control group (conventional treatment) and experimental group (conventional treatment + ulinastatin injection). The baseline data on admission were compared between the two groups. The echocardiographic indexes [mitral peak velocity of early filling/early diastolic mitral annular velocity (E/e'), early diastolic mitral annular velocity (e'), mitral peak velocity of early filling/ mitral peak velocity of late filling (E/A), and tricuspid regurgitation rate (TRV)], myocardial damage-related and cardiac function-related indicators [troponin I (cTnI), N terminal pro B type natriuretic peptide (NTproBNP)] and inflammation-related indicators [C-reaction protein (CRP), procalcitonin (PCT), erythrocyte sedimentation rate (ESR)], length of ICU stay, duration of infection control, duration of vasoactive drug use and 28-day mortality were observed and compared between the two groups on admission and 7 days after treatment.Results:On the 7th day after treatment, the levels of e 'and E/A in the experimental group were significantly higher than those in the control group, and the levels of E/e', TRV, cTnI, NTproBNP, CRP and PCT were significantly decreased ( P<0.05). There were no significant differences in duration of infection control and duration of vasoactive drug use between the experimental group and the control group ( P<0.05), but the length of ICU stay was shorter and 28-day mortality was significantly lower in the experimental group than in the control group ( P<0.05). Conclusions:Ulinastatin can reduce the degree of inflammatory response, relieve myocardial injury, improve left ventricular diastolic function, and reduce the length of ICU stay and 28-day mortality in patients with sepsis.

ABSTRACT

Cow′s milk protein allergy (CMPA) is one of the most common presentations of food allergy seen in early childhood.It is an abnormal immune response caused by cow′s milk protein.CMPA can be clinically subdivided into either immediate-onset IgE mediated or delayed onset non-IgE mediated, or both.At present, concerns regarding the early and timely diagnosis of CMPA have been high-lighted over the years and there are many expert consensus on CMPA in China, but these consensus did not distinguish IgE mediated or non-IgE mediated CMPA.In view of the obvious clinical differences between the two type of CMPA and non-IgE mediated CMPA is more common in infancy, experts focus on pediatric gastroenterology, allergy/immunology, dermatology, nutrition and child healthcare convened by the Allergy Prevention and Control Professional Committee of Chinese Preventive Medicine Association present this guideline to help practitioners in primary care settings to early recognize and make suitable management of non-IgE mediated CMPA in China.The guideline incorporates the cutting-edge international guidance and the actual situation of Chinese children describing in detail the types, clinical features, diagnosis and nutritional intervention of non-IgE mediated CMPA.There are 42 recommendations in 7 categories in total referring to the common questions related to non-IgE mediated CMPA.

ABSTRACT

OBJECTIVES@#To explore the optimal maintenance dose of caffeine citrate for preterm infants requiring assisted ventilation and caffeine citrate treatment.@*METHODS@#A retrospective analysis was performed on the medical data of 566 preterm infants (gestational age ≤34 weeks) who were treated and required assisted ventilation and caffeine citrate treatment in the neonatal intensive care unit of 30 tertiary hospitals in Jiangsu Province of China between January 1 and December 31, 2019. The 405 preterm infants receiving high-dose (10 mg/kg per day) caffeine citrate after a loading dose of 20 mg/kg within 24 hours after birth were enrolled as the high-dose group. The 161 preterm infants receiving low-dose (5 mg/kg per day) caffeine citrate were enrolled as the low-dose group.@*RESULTS@#Compared with the low-dose group, the high-dose group had significant reductions in the need for high-concentration oxygen during assisted ventilation (P=0.044), the duration of oxygen inhalation after weaning from noninvasive ventilation (P<0.01), total oxygen inhalation time during hospitalization (P<0.01), the proportion of preterm infants requiring noninvasive ventilation again (P<0.01), the rate of use of pulmonary surfactant and budesonide (P<0.05), and the incidence rates of apnea and bronchopulmonary dysplasia (P<0.01), but the high-dose group had a significantly increased incidence rate of feeding intolerance (P=0.032). There were no significant differences between the two groups in the body weight change, the incidence rates of retinopathy of prematurity, intraventricular hemorrhage or necrotizing enterocolitis, the mortality rate, and the duration of caffeine use (P>0.05).@*CONCLUSIONS@#This pilot multicenter study shows that the high maintenance dose (10 mg/kg per day) is generally beneficial to preterm infants in China and does not increase the incidence rate of common adverse reactions. For the risk of feeding intolerance, further research is needed to eliminate the interference of confounding factors as far as possible.

ABSTRACT

Objective@#Neonatal exposure to propofol has been reported to cause neurotoxicity and neurocognitive decline in adulthood; however, the underlying mechanism has not been established.@*Methods@#SD rats were exposed to propofol on postnatal day 7 (PND-7). Double-immunofluorescence staining was used to assess neurogenesis in the hippocampal dentate gyrus (DG). The expression of p-Akt and p27 were measured by western blotting. The Morris water maze, novel object recognition test, and object location test were used to evaluate neurocognitive function 2-month-old rats.@*Results@#Phosphorylation of Akt was inhibited, while p27 expression was enhanced after neonatal exposure to propofol. Propofol also inhibited proliferation of neural stem cells (NSCs) and decreased differentiation to neurons and astroglia. Moreover, the neurocognitive function in 2-month-old rats was weakened. Of significance, intra-hippocampal injection of the Akt activator, SC79, attenuated the inhibition of p-AKT and increase of p27 expression. SC79 also rescued the propofol-induced inhibition of NSC proliferation and differentiation. The propofol-induced neurocognition deficit was also partially reversed by SC79.@*Conclusion@#Taken together, these results suggest that neurogenesis is hindered by neonatal propofol exposure. Specifically, neonatal propofol exposure was shown to suppress the proliferation and differentiation of NSCs by inhibiting Akt/p27 signaling pathway.

ABSTRACT

Objective:To investigate the value of quick sequential organ failure assessment (qSOFA) score in early identification for sepsis patients of different ages.Methods:A retrospective study was conducted. The clinical data of 1 529 patients with suspected infection in emergency department of Changshu No.2 People's Hospital from September 2017 to March 2020 were collected. All patients were assessed for qSOFA score, and the diagnosis and treatment were recorded. Sepsis-3 was defined as the diagnostic criteria for sepsis. All the patients were divided into five groups according to age, youth group (< 45 years old), middle-aged group (45-59 years old), presenile group (60-74 years old), elderly group (75-89 years old), and longevity group (≥90 years old). The patients' examination results, diagnosis and treatment status were collected. The distribution of different scores of qSOFA was analyzed to calculate the sensitivity, specificity, positive predictive value and negative predictive value of different qSOFA scores for the diagnosis of sepsis in patients with suspected infection of different ages. The receiver operator characteristic curve (ROC curve) was drawn to analyze the diagnostic value of qSOFA score for sepsis in patients with suspected infection at different ages.Results:Of 1 529 suspected infection patients, there were 67 patients in youth group, 129 patients in middle-aged group, 465 patients in presenile group, 778 patients in elderly group and 90 patients in longevity group. There were significant differences in lactic acid (Lac), total bilirubin (TBil), creatinine (Cr), qSOFA score and the increased value of SOFA score compared with the basic value (ΔSOFA) among the suspected infection patients at different ages. Among suspected infection patients at different ages, the patients with qSOFA score ≥ 1 were the most, and the proportion of sepsis patients was larger. Further analysis showed that qSOFA score ≥1 had a high diagnostic sensitivity in patients with suspected infection at different ages. In the youth group, the sensitivity was 84.4%, and the specificity was the highest (74.3%). Although qSOFA score ≥ 2 had a high specificity in the diagnosis of sepsis (all > 97%), its sensitivity was very low (all < 44%). In this study, all patients with a qSOFA score of 3 were sepsis, and the positive predictive value of the diagnosis of sepsis in each group was 100%. ROC curve analysis showed that the area under ROC curve (AUC) of qSOFA score for the diagnosis of sepsis in all suspected infection patients was 0.771 [95% confidence interval (95% CI) was 0.747-0.794], when the best cut-off value was 0.5, the sensitivity was 93.4% and the specificity was 45.6%. Among suspected infection patients of all ages, the accuracy of qSOFA score in the diagnosis of sepsis in the youth group and the longevity group was relatively high, with AUC (95% CI) of 0.825 (0.724-0.927) and 0.837 (0.756-0.917), respectively; when the best cut-off value was 0.5, the sensitivity was 84.4% or 92.2%, and the specificity was 74.3% or 56.4%, respectively. Conclusions:qSOFA score has an early diagnosis value for sepsis, especially in the patients aged < 45 years old or ≥ 90 years old. Using qSOFA score ≥2 to screen patients with suspected infection is likely to cause missed diagnosis.

ABSTRACT

Objective@#To explore the predictive values of routine blood test results for iron deficiency (ID) screening in children.@*Methods@#Routine blood test results and serum ferritin (SF) levels from 1 443 healthy children (862 boys, 581 girls) aged 6 months to 18 years, who were seen for well-child visits between June 2017 and May 2019 in Children′s Hospital, Zhejiang University School of Medicine, were retrospectively analyzed. ID was defined as SF<20 μg/L, iron deficiency anemia (IDA) as ID with anemia (hemoglobin(Hb)<110 g/L at 6 months-5 years of age, Hb<120 g/L at 6-18 years of age), non-anemia ID as ID without anemia, non-ID anemia as SF≥20 μg/L with anemia, and healthy control subjects as those with SF≥20 μg/L but without anemia. The blood test results including Hb, mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration (MCHC), red blood cell distribution width (RDW), and the percentage of low hemoglobin density (LHD) of healthy control, non-anemia ID, non-ID anemia, and IDA groups were compared by analysis of variance (ANOVA) or non-parametric test, quantitative data were described as ±s or M(interquartile range), and receiver operating characteristic curve (ROC) analysis was applied to assess predictive values of routine blood test results and LHD for detecting IDA and ID.@*Results@#Among 1 443 children with median age of 2.1(3.3) years, 1 061 children were in healthy control group, 292 in non-anemia ID group, 43 in non-ID anemia group and 47 in IDA group. The prevalence of ID was much higher than that of anemia (23.5% (339/1 443) vs. 6.2% (90/1 443) , χ2=169.76, P<0.01). Compared with control group, non-anemia ID group showed higher LHD (0.088 (0.093) vs.0.073 (0.068), P<0.01) and RDW (0.131±0.013 vs. 0.126±0.008, P<0.01), lower MCV ((80±4) vs. (83±4) fl, P<0.01) and MCHC values ((326±9) vs. (329±8) g/L, P<0.01). IDA group showed higher LHD (0.322(0.544)) and RDW (0.151±0.018), lower MCV ((73±6) fl) and MCHC values((309±14) g/L) than non-anemia ID group (all P<0.01). The area under curve (AUC) values of MCHC, LHD, RDW and MCV for detecting ID were 0.63 (95%CI: 0.60-0.67), 0.63 (95%CI:0.60-0.67), 0.67 (95%CI: 0.63-0.70) and 0.73 (95%CI: 0.69-0.76) respectively. With cutoff limits (MCV<80.2 fl, RDW>0.131 or MCHC<322 g/L), MCV, RDW and MCHC showed higher sensitivity for screening ID than hemoglobin (0.540, 0.469 and 0.336 vs. 0.139, χ2=121.70, 87.47, 35.56, all P<0.01).@*Conclusion@#MCV, RDW and MCHC can be used to screen ID in primary health care settings.

ABSTRACT

<b>Objective::To investigate the feasibility of near-infrared spectroscopy for detecting the coating film thickness of Tianshu tablets. <b>Method::Nine batches of Tianshu tablets were taken during the coating process. Then, their near-infrared diffuse reflection spectra were collected. The sample set was divided into calibration set and validation set by Kennard-Stone algorithm. The preprocessing method was selected. The synergy interval partial least squares (siPLS) and moving window partial least squares (mwPLS) were employed to screen the optimal spectral interval. And the corresponding quantitative calibration model of partial least squares (PLS) were established. Some evaluation parameters were adopted to assess the performance of the model. <b>Result::The method of first derivative and Norris Derivative smoothing combined with standard normal variate transformation was suitable for processing the spectra. The optimal PLS model was established in the preferred band interval of siPLS. The correlation coefficient between the predicted value and the measured value of calibration set was 0.966, and the correlation coefficient between the predicted value and the measured value of validation set was 0.991.Both root mean square error of calibration (RMSEC) and root mean square error of prediction (RMSEP) values were small, which showed the fitness and predictive performance of the model were favorable. <b>Conclusion::The near-infrared spectroscopy technique can be used to determine coating film thickness of Tianshu tablets with high accuracy, which provides technical supports for the in-line determination of coating thickness in the production process of traditional Chinese medicine tablets.

ABSTRACT

Birth weight is an important index for assessing intrauterine nutritional environment and outcome of birth. There are more than 1 000 000 neonates born with low birth weight in China every year. Furthermore,the rate of macrosomia is increasing. A lot of researches on birth weight have found that low birth weight or macrosomia is not only associated with newborn or infant mortality and morbidity,but also related to poorer physical growth,neurodevelopment,and increasing risk of chronic metabolic and cardiovascular diseases in adulthood. In this article,we reviewed the latest studies of epidemiological characteristics and pathogenesis of low birth weight and macrosomia,as well as its effects and mechanisms on neurocognitive development,metabolic disease and cardiovascular disease. It may be beneficial to the health and development of lifetime to have a proper recognition of birth weight,prevent the risk factors associated with inappropriate birth weight and monitor and optimize growth and development after birth.

ABSTRACT

Objective@#To characterize the relations between the practice of parenting and associated factors on children (0-5 years old) in urban areas of China, in order to provide evidence for promoting the early development of children and to provide positive guidance and service programs on parenting.@*Methods@#A total of 4 515 parents from 15 cities (14 provinces) were surveyed with a self-administered questionnaire. Parenting and Family Adjustment Scales (PAFAS) was used, including parameters as: consistency and coercive parenting, positive encouragement, parent-child relationship and parental emotion adjustment, family relationship and parental teamwork aspects, etc. Both single factor analysis and multiple linear regression were used to examine the associations between parenting practice, individual, parental and family factors.@*Results@#The mean score of PAFAS was 21.00 (15.00-28.00), associated with factors as children’s age, only-child family, premature delivery, father’s education level, confidence on parenting, problems regarding the parental mood, annual family income, family structure and behavior on seeking professional help, etc. Results showed that there were big differences on the practice of parenting in China and influenced by variety of factors.@*Conclusions@#The general situation of parenting was well, in the urban areas of China. The practice of parenting was associated with a series of individual, parental and family factors. Programs on improving the parenting skills and promoting the early development of children, should be highlighted.

ABSTRACT

Objective To explore the correlation of disease activity with the primary syndromes of deficiency and excess types of lupus nephritis(LN). Methods A retrospective study was carried out in 134 LN patients,and the LN patients were differentiated into deficiency syndrome(deficiency group)and excess syndrome(excess group). The disease activity related indicators of systemic lupus erythematosus disease activity index(SLEDAI)scores, complements, inflammation indexes, and urine indicators were compared between the two groups. Results Of the 134 LN patients,33 cases were differentiated into excess syndrome,and 101 cases were differentiated into deficiency syndrome. According to the SLEDAI scores, 9.09% of the patients in excess group were inactive, 4.95% of the patients in deficiency group were inactive, and most of the patients in the two groups were at severe active stage. There was no significant difference of SLEDAI scores between the two groups(P>0.05) . The differences of complement C3 and C4 , inflammation indexes of C-reactive protein(CRP)and erythrocyte sedimentation rate(ESR),urine protein,and urine occult blood were also insignificant between the two groups (P>0.05). Conclusion There is no correlation between deficiency-excess syndrome differentiation and disease activity of LN. Most of the LN patients with deficiency syndrome are at active stage,but not at remission stage.
