ABSTRACT

Objective:To study the correlation of serum tenascin C (TNC) and bronchopulmonary dysplasia (BPD) comorbid pulmonary hypertension (PH) in preterm infants.Methods:From January 2017 to June 2020, preterm infants (gestational age<32 weeks) diagnosed of severe BPD admitted to the Neonatal Intensive Care Unit of our hospital were prospectively studied. Comorbidity of PH was evaluated using echocardiography and the infants were assigned into PH (+) group and PH (-) group. At the same time, serum TNC was examined and the correlation between serum TNC level and PH in infants with severe BPD was analyzed.Results:A total of 59 infants with severe BPD were enrolled, including 21 cases comorbid PH (35.6%). The serum TNC level in the PH (+) group was significantly higher than the PH (-) group [(123.7±41.1) ng/ml vs. (78.2±20.2) ng/ml, P<0.05]. Correlation analysis showed a positive correlation between the serum TNC level and systolic pulmonary artery pressure (sPAP) ( r=0.861, P<0.001).The area under the receiver operating characteristic curve of serum TNC predicting BPD comorbid PH was 0.884. The sensitivity and specificity of serum TNC predicting BPD comorbid PH were 84.0% and 76.9% with TNC≥87.7 ng/ml as the cut-off. Conclusions:Severe BPD comorbid PH is common. The serum TNC level in infants with severe BPD comorbid PH is increased and positively correlated with sPAP. The serum TNC level has certain clinical value in predicting and evaluating the severity of BPD comorbid PH.

ABSTRACT

Objective:To observe and analyze the macular choroidal thickness and choroidal blood perfusion (CBP) in eyes with idiopathic macular hole (IMH) and their correlation.Methods:A cross-sectional observational clinical study. From March 2019 to October 2021, 60 IMH patients with 60 eyes (IMH group) and 60 healthy volunteers with 60 eyes (control group) who consecutively visited Department of Ophthalmology of The First Affiliated Hospital of Zhengzhou University were included in the study. Among the 60 eyes in the IMH group, 8, 8, 15, and 29 eyes were at stage Ⅰ, Ⅱ, Ⅲ, and Ⅳ, respectively. There was no significant difference in age, spherical equivalent power and axial length between the two groups ( t=1.327, 0.157, 0.542; P>0.05). The average macular choriodal thickness (AMCT) and CBP in different regions of the macular region of the examined eye were measured using a swept-frequency light source optical coherence tomography scanner. According to the zoning method for the treatment of diabetic retinopathy, the choroid within 6 mm of the fovea was divided into 3 concentric circles with the fovea as the center. They are the central area with a diameter of 1 mm, the inner ring area of 1-3 mm, and the outer ring area of 3-6 mm; the inner ring area and the outer ring area were divided into 4 areas by 2 radiations respectively, including the upper part of the inner superior (IS), the lower part of the inner inferior (Ⅱ ), and the nasal side of the inner nasal (IN), inner temporal (IT), outer superior (OS), outer inferior (OI), outer nasal (ON), outer temporal (OT), a total of 9 regions. The distribution characteristics of AMCT and CBP in different regions were observed. The correlation between AMCT and CBP was analyzed by Pearson correlation; the correlation between AMCT, CBP and IMH stage was analyzed by Spearman correlation. Results:Compared with the eyes of the control group, the AMCT of the affected eyes in the IMH group was significantly thinner in all areas of the macula, and the difference was statistically significant ( t=2.378, 4.641, 2.888, 3.390, 3.575, 4.870, 4.077, 4.946, 4.578; P<0.05). Compared with the control group, the CBP in the OS and OT regions of the affected eyes in the IMH group was significantly lower, the difference was statistically significant ( t=3.424, 4.516; P<0.05). The results of Pearson correlation analysis showed that there was a significant positive correlation between AMCT and CBP in the OT region ( r=0.314, P<0.001). Spearman correlation analysis showed that there was a significant positive correlation between AMCT and IMH staging in each region ( r=0.375, 0.374, 0.289, 0.379, 0.441, 0.392, 0.303, 0.341, 0.292; P<0.05). There was no significant correlation between CBP and IMH staging in IN, OI and OT regions ( r=-0.138, -0.016, -0.221; P>0.05); CBP and IMH staging in other regions were significantly negatively correlated ( r=-0.560, -0.390,-0.819, -0.692, -0.329, -0.587; P<0.05). Conclusions:The choroidal thickness in the macular region of the eyes with IMH is significantly thinner than that of the normal subjects; there is choroidal hypoperfusion in local areas. There is a significant positive correlation between local regional AMCT and CBP; IMH stage is higher, the trend of AMCT in each region is thickening, and the CBP in most regions decrease.

ABSTRACT

Objective:To observe the effect of early goal directed sedation (EGDS) on cerebral oxygen metabolism in patients with acute brain injury.Methods:A prospective cohort study was conducted. A total of 108 patients with acute brain injury admitted to the intensive care unit (ICU) of the Third Medical Center of the PLA General Hospital from January 2015 to December 2019 were enrolled. According to the patient's condition, dexmedetomidine contraindication and tolerance, and combined with the wishes of patients' families, they were divided into EGDS group and on-demand sedation group. Routine treatments such as surgery, mechanical ventilation, dehydration and reduction of intracranial pressure with mannitol, hemostasis or antiplatelets therapy were given according to the patient's condition. All patients were continuously given sufentanil by intravenous infusion for analgesia. Patients in the EGDS group were sedated by continuously intravenous infusion of dexmedetomidine (0.2-0.7 μg·kg -1·min -1) for 72 consecutive hours. Patients in the on-demand sedation group received intravenous bolus of propofol (0.5-1.0 mg/kg) when treatments were interfered due to agitation. Hemodynamic indexes [heart rate (HR), mean arterial pressure (MAP), cerebral perfusion pressure (CPP), intracranial pressure (ICP)], sedation indexes [bispectral index (BIS)], severity indexes [acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, Glasgow coma score (GCS)] and cerebral oxygen metabolism indexes [jugular venous blood lactate (Lac), jugular venous oxygen saturation (SjvO 2), cerebral arterial oxygen content (CaO 2), cerebral extraction rate of oxygen (CERO 2), cerebral arteriovenous blood oxygen content difference (a-vDO 2)] were compared between the two groups before sedation and at 24, 48 and 72 hours of sedation. Results:① Among the 108 patients, 3 patients with cerebral hemorrhage received secondary surgery or had worsening of cerebral hernia were excluded. 105 patients were enrolled in the study, including 54 patients in the EGDS group and 51 patients in the on-demand sedation group. There were no statistically significant differences in gender, age, type of craniocerebral injury, GCS score, proportion of mechanical ventilation and operation ratio between the two groups. ② Compared with before sedation, Lac, CERO 2 and a-vDO 2 of both groups gradually reduced over time of sedation while SjvO 2 and CaO 2 were gradually higher. Those changes were more quickly in the EGDS group, Lac, SjO 2, CERO 2 and a-vDO 2 significantly improved at 24 hours of sedation compared with those before sedation. Above indexes at 72 hours of sedation in the EGDS group were obviously better than those in the on-demand sedation group [Lac (mmol/L): 1.81±0.31 vs. 2.19±0.12, SjvO 2: 0.714±0.125 vs. 0.683±0.132, CaO 2 (mL/L): 201.21±15.25 vs. 179.65±14.07, CERO 2: (27.87±3.66)% vs. (33.00±2.58)%, a-vDO 2 (mL/L): 44.32±5.68 vs. 48.57±8.22, all P < 0.05]. ③ Compared with before sedation, HR, MAP and ICP decreased in the two groups over time while CPP, BIS and GCS score showed increasing trend, especially more quickly in the EGDS group, HR at 24 hours of sedation, MAP, CPP, BIS and GCS score at 48 hours significantly improved as compared with those before sedation. Hemodynamics and sedation related parameters and GCS score at 72 hours of sedation in the EGDS group were significantly better than those in the on-demand sedation group [HR (bpm): 70.69±7.80 vs. 79.85±9.77, MAP (mmHg, 1 mmHg = 0.133 kPa): 84.23±8.76 vs. 89.97±9.48, ICP (mmHg): 14.23±8.76 vs. 15.97±9.48, BIS: 60.56±24.58 vs. 56.86±33.44, GCS score: 8.06±3.63 vs. 7.86±2.98, all P < 0.05]. The APACHE Ⅱ scores were significantly reduced at 72 hours of sedation in both groups as compared with those before sedation, while there was no statistical difference between the two groups. Conclusion:Compared with the on-demand sedation, EGDS could reduce cerebral oxygen metabolism, improve the coma degree, and reduce the severity of the disease in patients with acute brain injury.

ABSTRACT

The medical fungus Hirsutella sinensis has been used as a Chinese folk health supplement because of its immunomodulatory properties. Our previous studies established the antifibrotic action of Hirsutella sinensis mycelium (HSM) in the lung. The epithelial-mesenchymal transition (EMT) is involved in the pathogenesis of idiopathic pulmonary fibrosis. The present study investigates the role of HSM in mediating EMT during the development of pulmonary fibrosis. HSM significantly inhibits bleomycin (BLM)-induced pulmonary fibrosis by blocking the EMT. In addition, the expression levels of midkine are increased in the lungs of the BLM-induced group. Further analysis of the results indicates that the mRNA level of midkine correlated positively with EMT. HSM markedly abrogates the transforming growth factor β-induced EMT-like phenotype and behavior in vitro. The activation of midkine related signaling pathway is ameliorated following HSM treatment, whereas this extract also caused an effective attenuation of the induction of EMT (caused by midkine overexpression) in vitro. Results further confirm that oral medication of HSM disrupted the midkine pathway in vivo. Overall, findings suggest that the midkine pathway and the regulation of the EMT may be considered novel candidate therapeutic targets for the antifibrotic effects caused by HSM.

ABSTRACT

OBJECTIVE@#To explore the genetic basis for a child with mental and motor retardation, language impairment, facial dysmorphism and epilepsy.@*METHODS@#Whole exome sequencing was carried out to detect pathogenic variant in the proband, and candidate variant was selected based on his phenotype. Sanger sequencing was used to verify the variant in the proband, his parents and other family members.@*RESULTS@#The proband was found to carry a frameshifting mutation of MBD5 gene, namely c.2217delT (p.F739Lfs*6), which was inherited from his mother and unreported previously. Sanger sequencing confirmed that his brother carried the same mutation with a similar phenotype. His mother also had poor language expression when she was young, in addition with poor academic performance, though she could do some housework and had no history of convulsion.@*CONCLUSION@#A novel pathogenic variant of the MBD5 gene was discovered, which has enriched the mutational spectrum of the MBD5 gene. Above discovery has enabled genetic counseling and prenatal diagnosis for the family.

ABSTRACT

Objective:To explore the value of growth differentiation factor 15 (GDF15) in the early diagnosis of acute chest pain.Methods:A total of 96 patients with acute chest pain admitted to the Emergency Department of Hainan Hospital of PLA General Hospital from January to November 2020 were retrospectively collected. The sex, age, troponin T, creatine kinase, creatine kinase isoenzyme, GDF15 and B-type natriuretic peptide of patients within 30 min after admission were recorded, and the differences of each index in different groups were compared. ROC curve was drawn to evaluate the diagnostic value of GDF15 and TNT/BNP in acute coronary syndrome (ACS). The Gensini score, left ventricular ejection fraction, length of stay in hospital and the number of stents were calculated, and the correlation between these indexes and GDF15 concentration was evaluated.Results:The general trend of acute chest pain was more male than female (72.92% vs. 27.08%) , the oldest group was the UA group (64.67 ± 13.87) years old , the youngest group was cardiac arrest group (47.29 ± 9.99) years old . There were higher rates of hypertension in the STEMI group, NSTEMI group and UA group, and none of the groups showed significant advantage in diabetes. The GDF15 concentration was higher in ACS related chest pain group [(2.360 ± 1.710) ng/mL vs. (1.380 ± 1.040) ng/mL, P<0.01]. The area under the Receiver Operating Characteristic Curve (AUC) of GDF15 combined with TNT was up to 0.863. GDF15 concentration was negatively correlated with ejection fraction, positively correlated with Gensini score, positively correlated with the number of stents implanted, and positively correlated with the length of hospital stay. Conclusions:GDF15 is valuable in the diagnosis and prognosis of acute chest pain. The combination of GDF15 and TNT can improve the diagnostic rate of ACS.

ABSTRACT

Objective:To explore the early warning and prediction value of GDF15 for sudden death patients.Methods:From January to December 2018, 49 patients with sudden death who were treated in the Emergency Department of the First Clinical Center of PLA General Hospital were included in the case group, and 46 healthy physical examiners in the Physical Examination Center of the Hospital were randomly selected as the control group. The general situation, comparison of myocardial markers and analysis of the basic data of the case group were carried out, so as to evaluate the early warning value of each myocardial marker in sudden death.Results:Patients aged 40-49 years old accounted the highest proportion among sudden death cases, reaching 26.54%. Sudden death under 60 years old accounted for 59.19%, and the ratio of male to female was 3.83:1. There were significant differences between the case group and the control group in CK-MB [(41.35±98.38) vs. (3.13±2.17), P=0.009], CK [(2652.82±6845.66) vs. (102.73±47.93), P=0.012], and GDF15 [(549.80±809.79) vs. (115.70±167.42), P=0.001]. At the same time, the AUC value of GDF15 was 0.816, which has the highest diagnostic value for sudden death. And CK-MB, CK and GDF15 had no correlation with age. Conclusions:GDF15, as a biological marker, has a good early warning function in sudden death.

Kaplan Meier survival curves of ⅢA and ⅢB, T3N0M0 (ⅢA), T1-2N1M0 (ⅢB) and T3N1M0 (ⅢB) were drawn and compared. Single factor analysis and Cox multiple factor regression analysis were used to analyze the relation between clinical characteristics, treatment plan, stage Ⅲ subtype and prognosis. Results One-year survival rate of stage ⅢB gallbladder cancer patients was 49.70%, higher than those of stage ⅢA(36.41%); the 1-year survival rate of stage T1-2N1M0 (ⅢB) gallbladder cancer patients was 65.52%, higher than those of stage T3N0M0 (ⅢA) (36.41%) and stage T3N1M0 (ⅢB) (37.05%). According to Cox multivariate analysis, age, tumor grade, tumor size, operation mode, radiotherapy, chemotherapy, AJCC 8th TNM specific subtype and T stage were independent related factors affecting the prognosis of stage Ⅲ GBC patients (P < 0.01). Conclusion The overall survival of stage ⅢB GBC is better than that of stage ⅢA. The risk of stage Ⅲ GBC death was T1-2N1M0 (ⅢB) < T3N0M0 (ⅢA) < T3N1M0 (ⅢB). Radical cholecystectomy (number of dissected lymph node≥6), radiotherapy and chemotherapy are beneficial to the improvement of prognosis of stage Ⅲ GBC patients.

ABSTRACT

OBJECTIVE@#To explore the genetic basis for a couple with normal phenotype but repeated pregnancies with fetuses affected by osteogenesis imperfecta.@*METHODS@#Whole exome sequencing (WES) was carried out on fetal specimens and parental DNA to detect potential pathologic variants. Suspected variants were verified by Sanger sequencing. Semen sample of the husband was collected for the extraction of genome DNA, and whole genome amplification (WGA) was performed for single sperms isolated from the sample.@*RESULTS@#WES has identified a heterozygous c.1378G>A (p.G460S) variant of the COL1A2 gene in the fetus, which was predicted to be pathogenic but not detected in peripheral blood samples of both husband and wife. The heterozygotic variant was detected in semen DNA from the husband. Among 15 spermatozoa, 4 were found to harbor the variant.@*CONCLUSION@#The fetus was diagnosed with osteogenesis imperfecta, and the gonadal mosaicism probably accounted for the repeated abnormal pregnancies. Possibility of gonadal mosaicism should be considered when counseling couples with normal phenotype and genotype but recurrent abnormal pregnancies and/or births of children with similar phenotypes and genetic variants.

ABSTRACT

OBJECTIVE@#To study the genotype and phenotype of fetuses with 22q11.2 microdeletion and other abnormalities such as cardiac malformation and cleft palate.@*METHODS@#Fetal ultrasound was carried out at 12 weeks to 20 to 24 weeks of gestation. After excluding the chromosomal karyotype abnormality, single nucleotide polymorphism (SNP) array was used to detect copy number variations of 5 fetuses with heart development abnormality or other structural abnormalities. The fetus with 22q11.2 microdeletion and its parents were also subjected to multiplex ligation-dependent probe amplification (MLPA) assay.@*RESULTS@#SNP array analysis showed that the 5 fetuses had all carried a 2.27-3.02 Mb deletion of the 22q11.2 region. MLPA assay confirmed that LCR22-A-B was involved in all cases, and that all deletions were de novo in origin.@*CONCLUSION@#It is of great significance to exclude 22q11.2 microdeletions in fetuses with cardiac malformations. The deletion regions of these fetuses are similar but different, and the phenotypic difference is related to their genotypes.
