ABSTRACT

OBJECTIVES@#To study the significance of interleukin-6 (IL-6) and interleukin-27 (IL-27) in the differential diagnosis of acute respiratory distress syndrome (ARDS) and neonatal respiratory distress syndrome (NRDS) in preterm infants.@*METHODS@#The preterm infants with the manifestation of respiratory distress who were treated in the Neonatal Diagnosis and Treatment Center, Children's Hospital of Chongqing Medical University, from March to November 2021, were enrolled in this prospective study. According to the diagnosis results, they were divided into two groups: ARDS group (n=18) and NRDS group (n=20). ELISA was used to measure the plasma levels of IL-6 and IL-27. The receiver operating characteristic (ROC) curve was used to analyze the value of each index in the diagnosis of ARDS.@*RESULTS@#The ARDS group had significantly higher plasma levels of IL-6 and IL-27 than the NRDS group (P<0.05). The ROC curve analysis showed that IL-6 had an area under the ROC curve (AUC) of 0.867 for the diagnosis of ARDS, with a sensitivity of 61.1% and a specificity of 95.0% at the cut-off value of 56.21 pg/mL. The ROC curve analysis also showed that IL-27 had an AUC of 0.881 for the diagnosis of ARDS, with a sensitivity of 83.3% and a specificity of 80.0% at the cut-off value of 135.8 pg/mL.@*CONCLUSIONS@#Plasma IL-6 and IL-27 can be used as biological indicators for early differential diagnosis of ARDS and NRDS in preterm infants.

ABSTRACT

Abstract Objective This study aimed to identify the predictors and threshold of failure in neonatal acute respiratory distress syndrome. Methods Newborns with severe acute respiratory distress syndrome aged 0-28 days and gestational age ≥36 weeks were included in the study if their cases were managed with non-extra corporal membrane oxygenation treatments. Patients were divided into two groups according to whether they died before discharge. Predictors of non-extra corporal membrane oxygenation treatment failure were sought, and the threshold of predictors was calculated. Results A total of 103 patients were included in the study. A total of 77 (74.8%) survived hospitalization and were discharged, whereas 26 (25.2%) died. Receiver operating characteristic analysis of oxygen index, pH, base excess, and combinations of these indicators demonstrated the advantage of the combination of oxygen index and base excess over the others variables regarding their predictive ability. The area under the curve for the combination of oxygen index and base excess was 0.865. When the cut-off values of oxygen index and base excess were 30.0 and −7.4, respectively, the sensitivity and specificity for predicting death were 77.0% and 84.0%, respectively. The model with base excess added a net reclassification improvement of 0.090 to the model without base excess. Conclusion The combination of oxygen index and base excess can be used as a predictor of outcomes in neonates receiving non-extra corporal membrane oxygenation treatment for acute respiratory distress syndrome. In neonates with acute respiratory distress syndrome, if oxygen index >30 and base excess <−7.4, non-extra corporal membrane oxygenation therapy is likely to lead to death.

ABSTRACT

Objective:To evaluate the effect of inhaled nitric oxide (NO) in gestational age ≤34 weeks preterm infants using meta-analysis.Method:A search from PubMed, Embase, Cochrane Central library, China National Knowledge Internet, China biomedical literature database, Wanfang and VIP database from establishment to June 2020.Result:A total of 17 randomized controlled studies were included. The subjects were premature infants (gestational age ≤34 weeks) who needed respiratory support. The total sample size was 4 033.Meta-analysis showed that no significant difference was found in mortality between treatment and control groups ( RR=1.00, 95% CI 0.89~1.11, P=0.930).Risk of bronchopulmonary dysplasia (BPD) at 36 w postmenstrual age (PMA) was significantly lower in preterm infants supplemented with iNO ( RR=0.89, 95% CI 0.82~0.97, P=0.006). Subgroup analysis showed the overall risk of mortality or BPD incidence was significantly reduced for birth weight >1 000 g infants treated with iNO ( RR=0.72, 95% CI 0.58~0.89, P=0.002). Risk of BPD incidence was significantly lower when beginning iNO in the first 7 d of life ( RR=0.83, 95% CI 0.70~0.98, P=0.030). Risk of BPD incidence was significant reduced in infants treated with 5 ppm or ≥10 ppm iNO ( RR=0.89, 95% CI 0.81~0.98, P=0.020; RR=0.90, 95% CI 0.81~0.99, P=0.030). There was a decrease in BPD incidence with iNO treatment time of either ≤7 d or >7 d ( RR=0.77, 95% CI 0.60~0.99, P=0.040; RR=0.87, 95% CI 0.77~0.97, P=0.010). There were no differences concerning mechanical ventilation duration and intracranial hemorrhage incidence ( P>0.05). Significant difference was found between treatment and control group with respect to reduction of oxygenation index (OI) ( WMD=-6.32, 95% CI -12.16~-0.48, P=0.030). Conclusion:For preterm infants born at less than 34 weeks who need respiratory support, iNO treatment may improve oxygenation and reduce the risk of BPD, but not decrease mortality, mechanical ventilation duration or intracranial hemorrhage incidence. A better treatment effect may be achieved if iNO treatment began in the first 7 d of life, and if the infant had a birth weight greater than 1 000 g.

ABSTRACT

OBJECTIVE@#To observe the changes of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and nerve function in patients with spinal tuberculosis before and after surgery, explore the timing of surgical intervention, and evaluate its influence on surgical safety.@*METHODS@#A retrospective analysis was conducted on 387 patients with spinal tuberculosis who received surgical treatment from March 2012 to March 2017, including 278 males and 109 females, aged 12 to 86 years old with an average of (49.9±19.1) years. There were 64 cases of cervical tuberculosis, 86 cases of thoracic tuberculosis, 76 cases of thoracolumbar tuberculosis and 161 cases of lumbar tuberculosis. There were 297 patients with single segmental involvementand 90 patients with multiple segmental involvement. Among them, 62 cases presented neurological damage, and preoperative spinal cord neurological function depended on ASIA grade, 5 cases of grade A, 8 cases of grade B, 39 cases of grade C, and 10 cases of grade D. According to the duration of preoperative antituberculosis treatment, the patients were divided into group A (256 cases, receiving conventional quadruple antituberculosis treatment for 2-4 weeks before surgery) and group B (131 cases, receiving conventional quadruple antituberculosis treatment for more than 4 weeks before surgery). The two groups were compared in terms of gender, age, preoperative complicated pulmonary tuberculosis, lesion site, lesion scope, surgical approach, drug resistance and other general clinical characteristics. ESR, CRP, visual analogue scale(VAS), Oswestry Disability Index (ODI), Frankel grade and postoperative complications were observed.@*RESULTS@#All 387 patients were followed up for 12 to 36 (18.3±4.5) months. There were no significant differences in gender, age, preoperative pulmonary tuberculosis, lesion site, lesion range, surgical approach, preoperative drug resistance and other characteristics between two groups. A total of 32 patients in two groups did not heal after surgery, with an incidence rate of 8.27%. The VAS and spinal cord dysfunction index of the two groups were significantly improved after surgery (@*CONCLUSION@#After 2-4 weeks of anti tuberculosis treatment before operation, patients with spinal tuberculosis could be operated upon with ESR and CRP in a descending or stable period. In principle, patients with spinal tuberculosis and paraplegia should be treated as soon as possible after active preoperative management of the complication without emergency surgery.

ABSTRACT

The Montreux definition established in 2017 made it clear that the neonates can not be excluded from the diagnosis of acute respiratory distress syndrome (ARDS), which supported the urge of emphasizing the specificity and importance of neonatal ARDS (nARDS) in the past ten years in China. Neonatal idiopathic respiratory distress syndrome is caused primarily by insufficient pulmonary surfactant system, which pathologically and clinically presented as typical respiratory distress syndrome. While the causes of nARDS often coexisted with underlying conditions, and its pathological and clinical features are a superposition of both respiratory distress syndrome and underlying conditions. Therefore, superimposition is the key to understanding the etiology, pathology, diagnosis, and treatment of nARDS, which is crucial for optimizing the clinical practice of nARDS.

ABSTRACT

Objective:To evaluate the role of hemopexin (HPX) in cerebral ischemia-reperfusion (I/R) injury in rats.Methods:One hundred and twenty healthy male Sprague-Dawley rats, aged 7-8 weeks, weighing 250-280 g, were divided into sham operation group (S group, n=36), cerebral I/R group (I/R group, n=36), vehicle group (V group, n=24), and HPX group ( n=24). The model of cerebral I/R injury was established by 120 min middle cerebral artery occlusion followed by reperfusion in anesthetized rats.At 6, 12 and 24 h of reperfusion, 4 rats in S group and I/R group were sacrificed, and the ischemic penumbra of the ipsilateral cerebral cortex was obtained to detect the expression of HPX by Western blot.In I/R, V and HPX groups, 0.9% normal saline 10 μl, 0.1% NaN 3 10 μl, and 1.86 mg/ml HPX 10 μl were injected into the lateral ventricle, respectively, immediately after reperfusion.Eight rats in each group were selected, and neurological deficit was scored at 1-7 days of reperfusion.Eight rats in each group were sacrificed at 1 and 7 days of reperfusion, brains were removed, and brain tissues were obtained for measurement of infarct size, and the percentage of infarct size was calculated. Results:Compared with S group, the expression of HPX in cerebral ischemic penumbra was significantly up-regulated at 24 h of reperfusion in I/R group, and the neurological deficit scores were significantly decreased at 1-7 days of reperfusion, and the percentage of cerebral infarct size was increased at 1 and 7 days of reperfusion in I/R, V and HPX groups ( P<0.05). Compared with I/R group, the neurological deficit scores were significantly increased at 1-7 days of reperfusion, and the percentage of cerebral infarct size was decreased at 1 and 7 days of reperfusion in HPX group ( P<0.05), and no significant change was found in the above indicators in V and I/R groups ( P>0.05). Conclusion:Up-regulation of HPX expression is the endogenous protective mechanism of cerebral I/R injury in rats.

ABSTRACT

OBJECTIVE@#To compare the clinical effects of three different methods of binding multi-fold rib graft, iliac bone graft and titanium mesh graft in tuberculosis of thoracic vertebra by approach of transverse rib process.@*METHODS@#A hundred and seven patients with tuberculosis of thoracic vertebra received surgical treatment from January 2010 to December 2016 were retrospectively analyzed. The patients were divided into three groups according different methods of bone graft. The surgical approach of the transverse rib process was used in all 107 patients, after thoroughly remove the necrotic tissue of tuberculosis, three different bone grafts were used respectively including iliac bone graft (36 cases, group A), binding multi-fold rib graft (35 cases, group B), titanium mesh bone graft (36 cases, group C). Perioperative indexes, the time required for bone graft during operation, intraoperation blood loss, the loss rate of the anterior edge of the lesion, Cobb angle, postoperative bone graft fusion time, spinal nerve recovery and Oswestry Disability Index were compared among three groups.@*RESULTS@#All the patients were followed up for 13 to 24 months, and the operation time required for bone graft was (23.2±4.1) min in group A, (23.8± 4.4)min in group B, and (25.5±4.2) min in group C, with no statistically significant difference among three groups (@*CONCLUSION@#The approach of transverse rib process for debridement of lesions can effectively treat tuberculosis of thoracic vertebra by binding multi-fold rib graft, iliac bone graft and titanium mesh graft, but binding multi-fold rib graft can effectively avoid iliac bone donor complications, and is an effective alternative to iliac bone graft, which is worth popularizing.

ABSTRACT

Abstract Objective: To give an overview of the Ortner's syndrome caused by an aortic arch aneurysm. Methods: By comprehensive retrieval of the pertinent literature published in the past two decades, 75 reports including 86 patients were collected and recruited into this study along with a recent case of our own. Results: The aortic arch aneurysms causing hoarseness were most commonly mycotic aneurysms. In this patient setting, in addition to the left recurrent laryngeal nerve, trachea was the most commonly affected structure by the aortic arch aneurysm. Surgical/interventional/hybrid treatments led to a hoarseness-relieving rate of 64.3%, much higher than that of patients receiving conservative treatment. However, hoarseness recovery took longer time in the surgically treated patients than in the interventionally treated patients. Conclusion: The surgical and interventional treatments offered similar hoarseness-relieving effects. Surgical or interventional treatment is warranted in such patients for both treatment of arch aneurysms and relief of hoarseness.

ABSTRACT

Objective:To observe the effect of Dabuyuan Jian on the synaptic plasticity of hippocampus and the brain derived neurotrophic factor (BDNF)/tyrosine kinase receptor (TrkB)/cyclic adenosine phosphate reactive element binding protein (CREB) signaling pathway in amyloid precursor protein/presenilil (APP/PS1) mice, and to explore its possible mechanism for improving synaptic plasticity. Method:Totally 36 APP/PS1 mice were divided into model group, donepezil group(6.5×10-4 g·kg-1·d-1) and Dabuyuan Jian group (13.2 g·kg-1·d-1), and another wild mice were set as control group. The mice in control group and model group received an equal volume of saline, and the mice in each group received drugs by gavage for 30 days. The learning ability and memory of mice in each group were detected by Morris water maze. The pathological changes of neurons and synapses in the hippocampus of each group were observed by Nissl staining and Golgi staining. The expression levels of postsynaptic density protein 95 (PSD95) and synaptophysin (SYN) in hippocampus of each group were detected by immunofluorescence (IF). The protein expression levels of BDNF, TrkB, CREB and phosphorylated CREB (p-CREB) in hippocampus were detected by Western blot. Result:As compared with the control group, the platform latency and total swimming distance of the model group were increased in the model group (P<0.01), with decreased times of crossing the platform and staying time in the target quadrant (P<0.01), the intracellular Nissl bodies of neurons in hippocampal CA3 area decreased or disappeared in model group, with decreased number of neurons and dendritic branches and decreased density of dendritic spine in hippocampal CA3 area of the mice (P<0.01), and the protein expression levels of SYN, PSD95, BDNF, TrkB and p-CREB in hippocampus of mice were also decreased in model group (P<0.05, P<0.01). As compared with the model group, the platform latency and total swimming distance were decreased in the donepezil group and Dabuyuan Jian group (P<0.05, P<0.01), with increased times of crossing platform and staying time in target quadrant (P<0.05, P<0.01), the number of Nissl bodies of neurons in hippocampal CA3 area was increased in the donepezil group and Dabuyuan Jian group, with increased number of neurons and dendritic branches and increased density of dendritic spine in hippocampal CA3 area of the mice, and the protein expression levels of SYN, PSD95, BDNF, TrkB and p-CREB in hippocampus of mice were increased in the donepezil group and Dabuyuan Jian group (P<0.05, P<0.01). Conclusion:Dabuyuan Jian can improve the synaptic plasticity of APP/PS1 double transgenic mice, and its mechanism may be related to its up-regulation of BDNF/TrkB/CREB signal pathway in mouse hippocampus.

ABSTRACT

Objective:To evaluate the effect of the semisolid food on the energy supplement in the parturients undergoing epidural labor analgesia.Methods:Ninety parturients requesting epidural labor analgesia with no pregnancy complications, at 38-41 week gestation, aged 20-35 yr, with body mass index of 19-30 kg/m 2, were divided into 3 groups ( n=30 each) using a random number table method: sports drink group (group A), millet gruel group (group B) and semisolid food group (group C). After admission to the hospital, different types of food were given on an empty stomach after drinking 300 ml of water, before labor analgesia and 1 h of labor analgesia, and the gastric emptying time (GET) was measured by the ultrasound assessment of gastric antrum.In the late stage of labor analgesia, patients drank different types of food as needed until the end of the third stage of labor.Visual analogue scale score was used to evaluate the maternal starvation, thirst and fatigue immediately after the end of the third stage of labor.The duration of labor, total amount of diet, energy supply per unit time, forceps-assisted vaginal delivery, pressing times of patient-controlled analgesia, occurrence of nausea and vomiting during labor, and volume of postpartum hemorrhage were recorded. Results:GET was significantly longer after labor analgesia than before labor analgesia in the three groups ( P<0.05). Compared with group A, GET was significantly prolonged after labor analgesia, scores for starvation and fatigue and total amount of diet were decreased, and the energy supply per unit time was increased in group B and group C, and the incidence of nausea and vomiting was significantly increased in group B and decreased in group C ( P<0.05). Compared with group B, GET was significantly shortened after labor analgesia, scores for fatigue were decreased, the energy supply per unit time was increased, and the incidence of vomiting was decreased in group C ( P<0.05). There were no statistically significant differences among the three groups in scores for thirst, duration of labor, incidence of forceps-assisted vaginal delivery, volume of postpartum hemorrhage, and pressing times of patient-controlled analgesia ( P>0.05). Conclusion:Compared with sports drinks and millet gruel, semi-solid food is more effective in supplementing energy for the parturients undergoing epidural labor analgesia.
