ABSTRACT
Abstract@#Non suicide self injury is highly common in adolescents, which is seriously threatening their physical and mental health. It is an important predictor of future suicide, and has become a focus of global public health concern. At present, the research on adolescent non suicidal self injury is still in its infancy, and its formation process is complex. The pathogenesis is not completely clear, and the relevant treatment studies are relatively few. The paper expounds the pathogenesis and treatment of the nonsuicidal adolescent NSSI from the perspectives of genetics, neurobiology, neuroimage and social psychology, aiming to provide a theoretical basis for adolescent NSSI prevention and intervention.

ABSTRACT
Objective:To analyze the effect of permissive hypercapnia(PHC) in premature infants with respiratory distress syndrome(RDS).Methods:Seventy preterm infants diagnosed with RDS from July 2019 to September 2020 were enrolled.The preterm infants were divided into PHC group[noninvasive high-frequency ventilation(NHFV)+ PHC, n=34] and non PHC group(NHFV, n=36)after injection of pulmonary surfactant by LISA method.Ventilator parameters, time of ventilation, oxygen therapy, enteral feedingand hospitalization days were compared between the two groups.The incidences of patent ductus arteriosus, intracranial hemorrhage, pneumothorax and ventilator-induced lung injury were recorded. Results:The time of mechanical ventilation, oxygen therapy, age of enteral feeding and hospitalization time in PHC group were less than those in non PHC group( P<0.05). PaO 2 and PaCO 2 of the two groups had no difference before mechanical ventilation treatment( P>0.05), and PaO 2 of the two groups had no difference after 24 hours of treatment( P>0.05). After treatment, PaCO 2 in non PHC group was significantly lower, and there was no significant difference in PHC group( P<0.05). There was no significant difference regarding ventilator parameters MAP and FiO 2 after 24 hours of treatment between the two groups( P>0.05), and the ΔP of PHC group was significantly lower than that of non-PHC group ( P<0.05). The incidence of ventilator-induced lung injury in PHC group was lower than that in non-PHC group( P<0.05). Conclusion:Compared with conventional ventilation therapy, PHC has similar therapeutic effect, but it can shorten the mechanical ventilation time, oxygen therapy time, age of enteral feeding and hospitalization days, and reduce the incidence of ventilator-induced lung injury.

ABSTRACT
Persistent pulmonary hypertension is a serious disease among new-borns.Despite the variety of causes, similar physiopathologic changes characterize this syndrome: a persistently raised pulmonary vascular resistance after birth, which leads to severe hypoxemia due to extrapulmonary shunting.The fundamental treatment is to reduce pulmonary vascular pressure and improve hemodynamics.Modern treatments such as inhaled nitric oxide, high-frequency oscillation ventilation, extracorporeal membrane oxygenation, and/or other pulmonary vasodilators could reduce mortality in neonatal persisitent pulmonary hypertension(PPHN). Inhaled nitric oxide is the main method for the treatment of PPHN, which can effectively improve oxygenation and reduce the need for extracorporeal membrane oxygenation(ECMO). The effect of inhaled nitric oxide is different with the gestational age changed.This article aims to summarize the clinical research progress of inhaled nitric oxide in the treatment of PPHN.

ABSTRACT
Objective To investigate the clinical effect of synchronized nasal intermittent positive pressure ventilation (SNIPPV) in the treatment of neonatal respiratory failure. Methods The clinical data of 52 neonates with respiratory failure treated in our hospital from January 2016 to January 2018 were retrospec-tively analyzed. According to the different treatment methods,they were divided into observation group and control group,26 cases in each group. The children in the observation group were treated with SNIPPV,while those in the control group were treated with synchronized intermittent positive pressure ventilation (SIPPV). Clinical efficacy,changes of blood gas analysis results before and after treatment,oxygen consumption time and hospital stay,and complications were compared between the two groups. Results The respiratory rate and heart rate of the two groups improved after treatment,but there were no significant differences between the two groups(P＞0. 05,respectively). The total effective rate of the observation group was 88. 5%,while that of the control group was 92. 3%,there was no significant difference between the two groups(χ2=0. 221, P＞0. 05). The pH,PaO2,PaCO2and oxygen saturation levels of 24 h after treatment in two groups were im-proved (P＜0. 05,respectively),but there were no significant differences between the two groups (P＞0. 05, respectively). Compared with the control group,the oxygen consumption time and hospitalization time of the observation group were significantly shorter, and the differences were statistically significant ( P ＜0. 05, respectively). And the observation group had fewer complications of ventilator associated pneumonia. Conclusion The effect of SNIPPV in the treatment of neonatal respiratory failure is significant. It could shorten the time of oxygen consumption and hospitalization and reduce the complications. It is worth populari-zing SNIPPV mode assisted ventilation.
ABSTRACT
Objective To explore the clinical features and discuss the diagnosis and treatment of neonatal sepsis caused by Lesteria. Methods We collected 22 newborn cases of Listeriosis admitted in neonatal intensive care unit from January 2014 to March 2018. The diagnosis of Listerosis was confirmed by blood culture. The clinical features, assistant examination results, drug sensitivity test and therapeutic effect were analyzed. The prognosis of Listeria sepsis was traced. Results Clinical features included dyspnea (15 cases),fever (3 cases),convulsion(3 cases). Ten cases complicated purulent meningitis,3 cases com-plicated pneumonia and 2 cases complicated shock,1 case complicated with neonatal necrotizing enterocolitis. Laboratory findings showed that white blood cell count ( >25 × 109/L) increased in 7 cases,decreased ( <5 × 109/L) in 5 cases,and C-reactive protein elevated in 21 cases. Head MRI showed intracranial hemorrhage (6 cases),neonatal white matter injury (5 cases) and hydrocephalus (1 case). Drug sensitivity test showed that Lesteria were sensitive to sulfamethoxazole, penicillin and ampicillin. Ten cases were cured, 6 cases improved,and 6 cases died. Conclusion Neonatal Listeria sepsis is a serious infectious disease. It is very important to recognize its early symptoms. Early detection of pathogens and targeted treatment can help improve prognosis and reduce mortality.
ABSTRACT
Objective To investigate the significance of permissive hypercapnia( PHC) in the treat-ment of neonates with respiratory failure using synchronized nasal intermittent positive pressure ventilation. Methods A retrospective study was conducted in 47 neonates with respiratory failure admitted to our NICU during January 2015 to December 2017. The subjects were divided into PHC group ( n =27, PaCO245 ～70 mmHg,1 mmHg=0. 133 kPa) and non-permissive hypercapnia( non-PHC) group( n=20,PaCO235～45 mmHg),respectively. The blood gas indicators(PaO2,PaCO2,PaO2/FiO2) before and after non-invasive ventilation treatment were compared;Ventilator parameters of the two groups ( PIP, PEEP, PiO2 , Ti ) were compared. Duration of oxygen therapy,non-invasive ventilation time,starting time of feeding,length of hospi-tal stay,the incidence of intracranial hemorrhage,air leakage,ventilation induced lung injury,and reintubation rate were compared between the two groups. Results After treatment,the blood gas indexes of PaO2 and OI at 24h in two groups were significantly higher than those before the treatment(P<0. 05). There was no sig-nificant difference on PaO2 and OI between two groups both before and after treatment. PaCO2 was lower in non-PHC group after treatment than that before the treatment(P<0. 05),but it showed no difference in PHC group (P>0. 05). The PIP value of the ventilator parameters in PHC group[(19. 9 ± 2. 7) mmHg] was sig-nificantly lower than that in the non-PHC group[(21. 7 ± 2. 3) mmHg](P<0. 05),and there was no statisti-cally significant difference between the two groups in the other ventilator parameters(P>0. 05). Duration of oxygen therapy,starting time of feeding,the time of using noninvasive ventilation,length of hospital stay in PHC group were shorter obviously than those in non-PHC group [ ( 79. 5 ± 10. 8 ) h vs. ( 92. 7 ± 19. 1 ) h;(34.3±8.8)hvs.(47.1±10.8)h;(67.4±12.3)hvs.(97.6±17.3)h;(11.0±4.6)dvs.(14.0±3.9) d](P<0. 05). The incidences of air leakage,and intracranial hemorrhage showed no significant difference between PHC group and non-PHC group(3/27 cases vs. 4/20 cases;3/27 cases vs. 2/20 cases)(P>0. 05). There was no significant difference between the two groups in the rate of reintubation of invasive ventilation after non-invasive ventilation failure ( 2/27 cases vs. 3/20 cases, P > 0. 05 ) . The incidence of ventilator induced lung injury was significantly lower in PHC group than that in non-PHC group ( 2/27 cases vs. 7/20 cases) ( P<0. 05 ) . Conclusion The effects of treating respiratory failure were similar in PHC group and non-PHC group. However,the PHC treatment could shorten the time of oxygen therapy,non-invasive ventila-tion time and hospitalization time,reduce the incidence of lung injury associated with ventilator. The clinical efficacy of PHC was more significant.
ABSTRACT
Objective To compare the clinical efficacy and the complications of two ventilation modes in the premature infants with neonatal respiratory distress syndrome(NRDS).Two different noninva-sive ventilation methods,synchronized nasal intermittent positive pressure ventilation(SNIPPV) and nasal continuous positive airway pressure(NCPAP) combined with Curosurf were used in the treatment of patients with NRDS.Methods A retrospective study was conducted in 46 infants with NRDS admitted to our hospi-tal during January 2016 to December 2017. The subjects were divided into SNIPPV group(n =24) and NCPAP group(n =22),respectively combined with Curosurf treatment. PaO2,PaCO2,oxygenation index (OI)(PaO2/FiO2),duration of oxygen therapy,noninvasive ventilation time,reintubation cases for the use of pulmonary surfactant,starting time of feeding,length of hospital stay,incidence of abdominal distention, intracranial hemorrhage,air leakage and other complications were compared between the two groups before and after treatment.Results After treatment,the blood gas indexes of PaO2and OI at 24 h both in the two groups were significantly higher than those before the treatment(P<0.05).After treatment,PaCO2was lower in both SNIPPV group and NCPAP group,but there was no statistical difference between the two groups(P>0.05).The OI at 24 h[(219 ± 23)mmHg,1 mmHg=0.133 kPa] was significantly higher in SNIPPV group than that in NCPAP group[(199 ± 26)mmHg](P<0.05).There was no difference in PaO2,PaCO2and OI between the two groups before treatment.Duration of oxygen therapy,starting time of feeding,the time of using noninvasive ventilation,length of hospital stay were shorter in SNIPPV group[(82.8 ± 11.7)h vs. (107.6 ± 20.3)h,(32.0 ± 8.0)h vs.(47.0 ± 7.2)h,(62.3 ± 10.8)h vs.(99.6 ± 17.1)h,(12.0 ± 3.5)d vs.(15.0 ± 3.8)d] than those in NCPAP group,the differences were statistically significant(P <0.05). Reintubation cases for the use of pulmonary surfactant and the incidence rate of abdominal distension, intracranial hemorrhage,air leakage showed no statistical significance between the two groups(P>0.05). Conclusion SNIPPV and NCPAP combined with Curosurf treatment have similar clinical effects in premature infants with NRDS. While SNIPPV can reduce the starting time of feeding,the time of using noninvasive ventilation,duration of oxygen therapy,length of hospital stay in the patients with NRDS,and the clinical effect is more significant.
ABSTRACT
Objective To investigate the effects of alveolar epithelial cells (AEC) on bronchopulmonary dysplasis(BPD) induced by hyperoxia in newborn rats.Methods The model of BPD induced by hyperoxia in neonatal rats was established.HE staining was used to observe the alveolar septum and alveoli development.The expression of the specific surfactant protein C (SPC) on type Ⅱ alveolar epithelial cells (AEC Ⅱ) and the expression of specific aquaporin 5 (aquaporin5 AQP5) on type Ⅰ alveolar epithelial cells (type Ⅰ alveolar epithelialcells,AECⅠ) were measured by immunohistochemistry.Results There was no significant difference of AQP5 between experimental groups and control group at 1 d,but significantly lower expression of AQP5 could be seen in experimental group1 on day3 (P ＜ 0.05).And then,the AQP5 level of lung tissue of newborn rats at 5,7,14d after experiment in groupl was significantly lower than that of in air control group (P ＜ 0.05).The expression of SPC protein had no significant difference between experimental groups and control group at 1 d,but the SPC level of lung tissue of newborn rats at 3,7,14d after experiment in group1 was significant lower than that of in air control group (P ＜ 0.05).Conclusion Hyperoxia exposure leads to the expression of SP-C and AQP5 decreased,which may be key points for the development of BPD.AECⅡ may play an important role in the repairation of alveolar epithelial cells in neonatal rats with BPD induced by hyperoxia.
ABSTRACT
Objective To observe the biological effects of magnetic fields of different intensities on microvascular endothelial cells in the human brain (HBMECs).Methods HBMECs were cultured in vitro under normal conditions and randomly divided into a control group and several magnetic induction groups——26 mT,62.5 mT,110.7 mT and 215.6 mT at the center pole.Any changes to the cytomembranes were observed 72 h after planking using the lactate dehydrogenase (LDH) method.Superoxide dismutase and malondialdehyde methods were used to detect cellular oxidation due to the magnetic field.An inverted microscope was used to observe any changes in cell morphology,and flow cytometry was employed to detect cell apoptosis.Results Compared with the control group,the LDH value of the 215.6 mT group was significantly higher,but there were no significant differences in oxidative damage,apoptosis or morphology observed.Moreover,there were no significant differences between the controls and the 26 mT,62.5 mT and 110.7 mT groups in any of the above measurements.Conclusion Magnetic fields of different intensity have different biological effects on HBMECs.A 215.6 mT magnetic field influences their cell membranes but causes no oxidative damage,cell apoptosis or morphological changes.These observations and the mechanism need further exploration.
