ABSTRACT
Objective:To explore the scheme of assigning rational scores to the Modified Pediatric Nutritional Risk Screening Tool for children with cerebral palsy(CP) at different Gross Motor Function Classification System(GMFCS) levels.Methods:The clinical data of 360 children with CP hospitalized in the Department of Children′s Rehabilitation, the Third Affiliated Hospital of Zhengzhou University from January to October 2019 were analyzed retrospectively.All the CP children at different GMFCS levels who met the inclusion criteria were subject to nutrition screening and assessment by using the Modified Pediatric Nutritional Risk Screening Tool and the Subjective Global Nutritional Assessment(SGNA) scale.The distribution of malnutrition rates assessed by the SGNA scale among the children at different GMFCS levels was examined.Data between groups were compared by the χ2 test.Children at different GMFCS levels were divided into different subgroups according to the statistical difference.Then, 0 or 1 score was assigned to the Modified Pediatric Nutritional Risk Screening Tool in different subgroups, and different combinations were formed.The nutritional risk screening results of different combinations were evaluated by using the SGNA scale assessment results as a reference. Results:In children with CP, the risk detection rate and incidence rate of malnutrition were 58.1%(209/360) and 36.9%(133/360), respectively.There was no significant difference in the incidence rate of malnutrition between GMFCS Ⅱ and GMFCS Ⅲ, as well as between GMFCS Ⅳ and GMFCS Ⅴ(all P>0.05). Therefore, children with CP were divided into 3 subgroups, namely, group Ⅰ, group Ⅱ to Ⅲ, and group Ⅳ to Ⅴ.Different CP disease scores were given to the Modified Pediatric Nutritional Risk Screening Tool in 3 subgroups, forming 3 different protocols[protocol 1 (0, 0, 1 point); protocol 2(0, 1, 1 point); current protocol (1, 1, 1 point)]. Taking the SGNA scale assessment results as a reference, the sensitivity of protocol 1, protocol 2 and current protocol were 85.7%, 92.5%, and 93.2% respectively.The specificity protocol 1, protocol 2 and current protocol were 81.1%, 78.0%, and 62.6%, respectively.And the Youden indexes of above three protocols were 0.668, 0.705, and 0.558, respectively.The Youden index of protocol 2 was relatively high. Conclusions:The Modified Pediatric Nutritional Risk Screening Tool can effectively identify the risk of malnutrition in children with CP.The scheme of assigning 0 points to children with GMFCS grade Ⅰ and 1 point to children with GMFCS grade Ⅱ to Ⅴ is more reasonable.
ABSTRACT
Objective:To explore the relationship between soft markers found in the first trimester (11-13 + 6 gestational weeks) ultrasound screening and fetal adverse pregnancy outcomes. Methods:Single pregnancy fetuses were selected from the Multicenter Clinical Study of First Trimester Screening in China during August 2017 to August 2020. The types and detection rate of soft markers during the first trimester were compared. The correlation between positive soft markers and adverse pregnancy outcomes was analyzed by binary Logistics regression.Results:A total of 16 625 fetuses with complete follow-up outcomes were included in the group. Six hundred and seven ultrasonic soft markers were detected in 556 fetuses with positive soft markers during the first trimester, and the first four most frequently occurred were increased nuchal translucency (NT) (2.08%, 345/16 625), echogenic intracardiac focus (EIF) (0.94%, 156/16 625), hypoplasia of fetal nasal bone (0.20%, 34/16 625), single umbilical artery (SUA) (0.19%, 31/16 625). Among 556 fetuses, the incidence of adverse pregnancy outcome in fetuses with two or more positive soft markers was 32.50% (13/40), which was significantly higher than fetuses with single positive soft marker (11.05%, 57/516), and the difference was statistically significant (χ 2=5.055, P<0.001). The incidence of adverse pregnancy outcome in positive soft markers fetus associated with structural abnormalities was 80.77% (21/26), which was significantly higher than fetuses with isolated positive soft marker (12.08%, 64/530), and the difference was statistically significant (χ 2=90.310, P<0.001). Binary logistic regression analysis showed choroid plexus cyst (CPC), SUA, echogenic bowel (EB), absent/reversed a-wave of ductus venosus, hypoplasia of fetal nasal bone, increased NT, and EIF were closely related to the adverse pregnancy outcomes (all P<0.05). However, there were no significant correlations between tricuspid regurgitation (TR), pyelectasis (PYE) and fetal adverse pregnancy outcomes (all P>0.05). Conclusions:The ultrasonic soft markers during the first trimester are of great significance in predicting fetal adverse pregnancy outcomes. For multiple positive soft markers or positive soft markers combined with structural abnormalities, more attention should be paid to them and comprehensive evaluation is required to be carried out.
ABSTRACT
Objective:To analyze the risk factors of bronchopulmonary dysplasia(BPD)in very preterm infants(VPI), and to provide scientific basis for the prevention and treatment of BPD in VPI.Methods:A prospective multicenter study was designed to collect the clinical data of VPI in department of neonatology of 28 hospitals in 7 regions from September 2019 to December 2020.According to the continuous oxygen dependence at 28 days after birth, VPI were divided into non BPD group and BPD group, and the risk factors of BPD in VPI were analyzed.Results:A total of 2 514 cases of VPI including 1 364 cases without BPD and 1 150 cases with BPD were enrolled.The incidence of BPD was 45.7%.The smaller the gestational age and weight, the higher the incidence of BPD( P<0.001). Compared with non BPD group, the average birth age, weight and cesarean section rate in BPD group were lower, and the incidence of male infants, small for gestational age and 5-minute apgar score≤7 were higher( P<0.01). In BPD group, the incidences of neonatal respiratory distress syndrome(NRDS), hemodynamically significant patent ductus arteriosus, retinopathy of prematurity, feeding intolerance, extrauterine growth restriction, grade Ⅲ~Ⅳ intracranial hemorrhage, anemia, early-onset and late-onset sepsis, nosocomial infection, parenteral nutrition-associated cholestasis were higher( P<0.05), the use of pulmonary surfactant(PS), postnatal hormone exposure, anemia and blood transfusion were also higher, and the time of invasive and non-invasive mechanical ventilation, oxygen use and total hospital stay were longer( P<0.001). The time of starting enteral nutrition, cumulative fasting days, days of reaching total enteral nutrition, days of continuous parenteral nutrition, days of reaching 110 kcal/(kg·d) total calorie, days of reaching 110 kcal/(kg·d) oral calorie were longer and the breastfeeding rate was lower in BPD group than those in non BPD group( P<0.001). The cumulative doses of amino acid and fat emulsion during the first week of hospitalization were higher in BPD group( P<0.001). Multivariate Logistic regression analysis showed that NRDS, invasive mechanical ventilation, age of reaching total enteral nutrition, anemia and blood transfusion were the independent risk factors for BPD in VPI, and older gestational age was the protective factor for BPD. Conclusion:Strengthening perinatal management, avoiding premature delivery and severe NRDS, shortening the time of invasive mechanical ventilation, paying attention to enteral nutrition management, reaching whole intestinal feeding as soon as possible, and strictly mastering the indications of blood transfusion are very important to reduce the incidence of BPD in VPI.
ABSTRACT
In the microscale, bacteria with helical body shapes have been reported to yield advantages in many bio-processes. In the human society, there are also wisdoms in knowing how to recognize and make use of helical shapes with multi-functionality. Herein, we designed atypical chiral mesoporous silica nano-screws (CMSWs) with ideal topological structures (e.g., small section area, relative rough surface, screw-like body with three-dimension chirality) and demonstrated that CMSWs displayed enhanced bio-adhesion, mucus-penetration and cellular uptake (contributed by the macropinocytosis and caveolae-mediated endocytosis pathways) abilities compared to the chiral mesoporous silica nanospheres (CMSSs) and chiral mesoporous silica nanorods (CMSRs), achieving extended retention duration in the gastrointestinal (GI) tract and superior adsorption in the blood circulation (up to 2.61- and 5.65-times in AUC). After doxorubicin (DOX) loading into CMSs, DOX@CMSWs exhibited controlled drug release manners with pH responsiveness in vitro. Orally administered DOX@CMSWs could efficiently overcome the intestinal epithelium barrier (IEB), and resulted in satisfactory oral bioavailability of DOX (up to 348%). CMSWs were also proved to exhibit good biocompatibility and unique biodegradability. These findings displayed superior ability of CMSWs in crossing IEB through multiple topological mechanisms and would provide useful information on the rational design of nano-drug delivery systems.
ABSTRACT
Objective:To provide a basis for policy support of Sino-foreign cooperation in the area of COVID-19, through exploring the composition, integration and main path of Sino-foreign scientific research cooperation in this field.Methods:Based on bibliometrics theory and the core database of Web of Science, Sino-foreign cooperative literatures in COVID-19 research area were screened to construct the keyword co-occurrence network. VOSviewer 1.6.16 software was used for cluster analysis, internal and external connectivity measurement and path exploration.Results:In COVID-19 research area, there were 61 countries, each of which had published more than 10 papers in cooperation with China. The proportion of Sino-US cooperative papers was the highest, accounting for 48.0%. The collaborative research field was divided into five clusters: basic medicine, clinical medicine, public mental health, epidemiology, and environmental impacts. The internal connectivity rate of basic medicine cluster was the highest(60.2%), and the lowest was epidemiology cluster(20.1%). The integration degree of basic medicine cluster and clinical medicine cluster was high, and the number of connecting nodes accounted for 27.7% and 21.9% in the two clusters. Through path analysis, a collaborative research main path of " emergent transmission-infection mechanism-clinical characteristics-anxiety" had been formed in the field.Conclusions:Sino-foreign scientific and technological cooperation in the field of COVID-19 was still in the early stage of development, but the research clusters had initially constructed. Some clusters showed high convergence and integration, and formed a main path of the collaborative research field. In order to realize the in-depth development of research in this field and the full utilization of cooperation resources, the health management department can formulate accurate health policies of scientific and technological cooperation for the development stages of different clusters according to the main path.
ABSTRACT
Objective:To investigate the relationship between double-triggering and abnormal movement of air in the lungs (pendelluft phenomenon) under pressure support ventilation (PSV).Methods:A prospective observational study was conducted, postoperative patients admitted to department of critical care medicine of Beijing Tiantan Hospital, Capital Medical University from April 1, 2019 to August 31, 2020 and received invasive mechanical ventilation with PSV mode were enrolled. Electrical impedance tomography (EIT) monitoring was performed. Airway pressure-time, flow-time, global and regional impedance-time curves were synchronously collected and analyzed offline. The volume of abnormal movement of air in the lungs at the beginning of inspiration was measured and defined as pendelluft volume. Double-triggered breaths were identified by trained researchers. Pendelluft volume during double-triggering was measured including the first triggered breath, the double-triggered breath, and the breath immediately following the double-triggered breath. Pendelluft volume was also measured for normal breath during the study. According to the frequency of double-triggering, patients were divided into severe (≥1 time/min) and non-severe double-triggering group. Pendelluft volume, parameters of respiratory mechanics, and clinical outcomes between the two groups were compared.Results:In 40 enrolled patients, a total of 9 711 breaths [(243±63) breaths/patient] were collected and analyzed, among which 222 breaths (2.3%) were identified as double-triggering. The Kappa of interobserver reliability to detect double-triggering was 0.964 [95% confidence interval (95% CI) was 0.946-0.982]. In 222 double-triggered breaths, pendelluft volume could not be measured in 7 breaths (3.2%), but the pendelluft phenomenon did exist as shown by opposite regional impedance change at the beginning of double-triggered inspiration. Finally, pendelluft volume was measured in 215 double-triggered breaths. Meanwhile, 400 normal breaths (10 normal breaths randomly selected for each patient) were identified as control. Compared with normal breath, pendelluft volume significantly increased in the first breath, the double-triggered breath, and the following normal breath [mL: 3.0 (1.4, 6.4), 8.3 (3.6, 13.2), 4.3 (1.9, 9.1) vs. 1.4 (0.7, 2.8), all P < 0.05]. Patients in severe double-triggering, pendelluft volume of normal breath and double-triggered breath were significantly higher than those in non-severe double-triggering group [mL: 1.8 (0.9, 3.2) vs. 1.1 (0.5, 2.1), P < 0.001; 8.5 (3.9, 13.4) vs. 2.0 (0.6, 9.1), P = 0.008]. Patients in severe double-triggering group had significantly higher respiratory rate than that in the non-severe double-triggering group (breaths/min: 20.9±3.5 vs. 15.2±3.7, P < 0.001). There were no significant differences in other respiratory mechanics parameters and main clinical outcomes between the two groups. Conclusions:During PSV, the abnormal movement of air in the lungs (pendelluft phenomenon) was more likely to occur in double-triggering especially in double-triggered breath. The more frequent the double-triggering occurred, the more serious the pendelluft phenomenon was. A higher pendelluft volume of normal breath and a higher respiratory rate were related to severity of double-triggering.
ABSTRACT
Objective:To monitor and investigate the long-term growth trend and nutritional status of very preterm infants (VPIs, born at gestational age between [28~31 +] weeks) with extrauterine growth restriction (EUGR) from birth to preschool period. Methods:VPIs who met with the following criteria were enrolled: infants born in Huai'an Maternity and Child Heath Care Hospital from January 1 to December 31, 2015; infants admitted to the Neonatal Medical Center and discharged alive; infants who received multi-disciplinary treatment in Child Care Division from discharge to preschool period. All of the VPIs were divided into the EUGR group and the non-EUGR group according to whether the weight at hospital discharge was below the 10 th percentile for corrected age in body weight. The weight for age Z score (WAZ), height for age Z score (HAZ), and head circumference for age Z score (HCZ) were calculated at each specified time point (at 40 weeks of age; at 1, 2, 3, 4, 5, 6 and 24 months of corrected age; and at 48 months of age). The growth trend and the nutritional status at 48 months of age were compared between the two groups. Results:1. A total of 53 VPIs were enrolled, among whom 35 cases were boys and 20 cases were with EUGR. The differences in the gestational age, birth weight, incidence of very low birth weight infants, neonatal respiratory distress syndrome (NRDS) and bronchopulmonary dysplasia (BPD) were all statistically significant between the EUGR group and the control group ( x 2= 2.306, 3.543, 10.852, 9.515, 0.001, respectively; all P<0.05). 2. The WAZ and HAZ of the EUGR group were lower at each time point. The WAZ at 40 weeks of age and the HAZ at 3 months of corrected age were significantly different between the two groups. From 40 weeks of age to 2 months of corrected age and from 6 months to 24 months of corrected age, the WAZ, HAZ and HCZ in both groups showed an increasing trend. However, the WAZ in the EUGR group and the WAZ, HAZ and HCZ in the non-EUGR group showed a declining trend from 24 months of corrected age to 48 months of age. 3. There was no significant differences in growth restriction incidence at each time point between the EUGR group and the control group. 4. The nutritional status showed no significant difference between the two groups, either ( P>0.05). Conclusions:Low gestational age, low birth weight, NRDS and BPD are the risk factors of EUGR. The growth trend of the EUGR VPIs shows an overall upward trend from hospital discharge to 24 months of corrected age but declined thereafter, while the nutritional status is good at 48 months of age. Thus, in addition to the integrated management, continuous monitoring of long-term growth and nutrient input after 24 months of age is required for VPIs.
ABSTRACT
Bipolar disorder is a common, highly disabling psychiatric disorder characterized by early onset, frequent episodes, high suicide risk, and chronic outcomes, and is associated with severe social dysfunction. The pathogenesis of bipolar disorder is still unclear, and current studies mainly focus on circadian rhythm abnormalities, including rhythm gene mutation, polymorphism, abnormal kinase expression, and rhythm abnormalities in neurotransmitter secretion and transport. It has been found that at any stage of bipolar disorder, whether prodrome, episode, or remission, patients exhibit circadian rhythm disruptions, including disrupted sleep-wake cycles, hormonal phase abnormalities, and irregular social rhythms. Based on this mechanism, the time therapy, such as light therapy, dark therapy, sleep deprivation and behavioral intervention, can rapidly improve the circadian rhythm of patients with bipolar disorder, achieve the goal of rapid relief of symptoms, with fewer side effects, low risk of switching to manic. In this paper, circadian rhythm mechanism, clinical manifestations and chronotherapy of bipolar disorder are reviewed to provide a basis for clinical diagnosis and treatment.
ABSTRACT
OBJECTIVE@#To explore the genetic etiology of a child suspected for β-ketothiolase deficiency by neonatal screening.@*METHODS@#All coding exons and flanking sequences of the ACAT1 gene were subjected to targeted capture and high-throughput sequencing. Suspected variants were verified by Sanger sequencing and bioinformatic analysis.@*RESULTS@#The child was found to harbor compound heterozygous variants of the ACAT1 gene, namely c.121-3C>G and c.275G>A (p. Gly92Asp). The c.121-3C>G variant was also detected in his father and two sisters, while the c.275G>A (p. Gly92Asp) was a de novo variant. A c.334+ 172C>G (rs12226047) polymorphism was also detected in his mother and two sisters. Sanger sequencing has verified that the c.275G>A (p. Gly92Asp) and c.334+172C>G (rs12226047) variants are located on the same chromosome. Bioinformatics analysis suggested both c.121-3C>G and c.275G>A (p.G92D) variants to be damaging. Based on the American College of Medical Genetics and Genomics standards and guidelines, the c.275G>A variant of the ACAT1 gene was predicted to be pathogenic (PS2+ PM2+ PM3+ PP3+PP4), the c.121-3C>G variant to be likely pathogenic (PM2+ PM3+ PP3+PP4).@*CONCLUSION@#The c.121-3C>G and c.275G>A variants of the ACAT1 gene probably underlay the pathogenesis of the child. Above finding has enriched the variant spectrum of the ACAT1 gene.

Objective:To compare the clinical effects of oblique lumbar interbody fusion (OLIF) and transforaminal lumbar interbody fusion (TLIF) in the treatment of lumbar degenerative scoliosis.Methods:A retrospective study was performed in 116 patients with lumbar degenerative scoliosis and spinal stenosis, who were admitted to Beijing Jishuitan Hospital from January 2015 to May 2018. The patients were divided into two groups according to the surgical method. Among them, 56 patients underwent the OLIF approach (OLIF group), consisting of 21 men and 35 women, with an average age of 65.2±8.7 years. According to Lenke-Silva classification, there were 41 cases of type II and 15 cases of type III in OLIF group. 60 cases underwent the TLIF approach (TLIF group), consisting of 19 men and 41 women, with an average age of 61.3±11.6 years. There were 43 cases of type II and 17 cases of type III in TLIF group. The preoperative and last follow up visual analogue scale (VAS) and Oswestry disability index (ODI) were compared between the two groups. The coronal and sagittal Cobb angle changing and the offset distance for apical midline of the lumbar vertebrae between pre-operation and last follow-up were measured. The respective complications of the two groups were collected.Results:For OLIF group, VAS decreased from 7.7±1.6 at pre-operation to 1.9±1.5 at the last follow up; for TLIF group, VAS decreased from 8.1±1.2 at pre-operation to 2.2±0.9 at the last follow up. Although there were obvious improve for both group compared pre-operation to last follow-up, there was no significant difference between the two groups. For OLIF group, ODI decreased from preoperative 47.5%±9.1% to last follow up 22.4%±6.7%; for TLIF group, ODI decreased from preoperative 52.6%±5.8% to last follow up 25.1%±8.4%. Obvious changes were foundin both group between pre-operation and last follow up, but there was no significant difference between the two groups. For sagittal lumbar cobb angle, OLIF group changed from preoperative 8.6°±5.7° to last follow-up 23.6°±4.3°. TLIF group changed from pre-operation 9.2°±4.2° to last follow-up 21.3°±4.8°. Obvious changes were found in both group between pre-operation and last follow up, while OLIF group had better improvement than TLIF group ( P=0.01). For lumbar coronal Cobb angle, OLIF group changed from preoperative 16.4°±9.6° to last follow-up 2.8°±2.1°, and TLIF group from preoperative 15.2°±7.8° to last follow-up 6.4°±2.7°. Obvious changes were found in both group comparing pre-operation to last follow up, while OLIF group had better improvement. The offset distance for apical midline of the lumbar vertebrae in OLIF group improved from preoperative 26.3±9.4 mm to 4.3±1.9 mm; TLIF group improved from preoperative 23.4±5.5 mm to 7.5±4.2 mm. Obvious changes were found between pre-operation and last follow up for both group, while OLIF group has better improvement compared to TLIF group ( t=-5.26, P=0.03). The fusion rate was 97.7% (127/130) in OLIF group, and 91.1% (164/180) in TLIF group. There was no statistically significant difference between the two groups ( χ2=1.15, P=0.097). The neural complication rate was 16.1% (9/56) in OLIF groupand 8.3% (5/60) in TLIF group. There was no statistical difference between the two groups ( χ2=1.63, P=0.201). The cage subsidence was 12.3% (16/130) in OLIF group and 21.9% (35/180) in TLIF group. There was statistically significant difference between the two groups ( χ2=4.53, P=0.03). Conclusion:OLIF can be considered as an effectivesurgical option for the treatment of lumbar degenerative scoliosis with spinal stenosis, since it can achieve similar clinical effects and better correction of coronal and sagittal imbalances compared to TLIF.
ABSTRACT

ABSTRACT
The ventilator-induced lung injury (VILI) was centered on the "static" characteristics of the mechanical ventilation in early phases (tidal volume, plateau pressure, positive end-expiratory pressure and driving pressure). But the "dynamic" characteristics of ventilation must not be ignored (respiratory rate and flow). Mechanical energy and mechanical power (the pace of performing energy load) regarding all factor have won wide spread attention. The energy generated by mechanical ventilation is mainly used to expand respiratory system and overcome resistance, a fraction of energy acts on lung tissues probably inducing "heat" and inflammation that is related to lung injury. The review described recent conceptual advances regarding the mechanical energy and power, and the relationship with VILI, hoping to help further understanding the risk factors for VILI.

The reuse of high-cost single-use medical devices (SUD) is permitted in many countries, such as the United States, Germany and the United Kingdom, but strict regulatory requirements must be met. In addition to regulatory policies and regulations, such as market access mode and special requirements on Good Manufacture Practice (GMP), there are strict technical requirements on the potential risk control and quality assurance system. Therefore, effective risk assessment and risk control technology are the keys to ensure effective quality control and safe use of SUDs. In this article, based on analyzing the technological requirements of the national regulatory on SUDs in the United States, Germany and Britain, and combined with the review from latest relevant literature, to discuss the strategies of how to carry out scientific risk assessment. Some risk control technologies on the reuse of SUDs are introduced, which will provide support for the further study on risk control strategies and regulatory decisions for the reuse of SUDs in China.
