ABSTRACT

Objective:To explore the potential genetic causes of unexplained neonatal encephalopathy.Methods:This retrospective study enrolled 113 infants diagnosed with unexplained neonatal encephalopathy and underwent genetic testing in the Children's Hospital of Hunan Province from January 2019 to May 2021. Perinatal data, clinical manifestations, electroencephalograph, brain MRI findings, genetic information, and prognosis of those patients were analyzed. T-test or Chi-square test were used for data analysis. Results:Of the 113 infants enrolled, 74 (65.5%) were males. The gestational age at birth was (38.6±1.5) weeks, and the birth weight was (2 957±561) g. The most common clinical manifestation was the disturbance of consciousness (83/113, 73.5%), followed by seizures (39/113, 34.5%). There were 38.2% (34/89) of the patients with abnormal brain MRI, and 80.4% (74/92) presented abnormal electroencephalography. Among the 113 infants, 60 (53.1%) had genetic abnormalities, including 48 with single nucleotide variations, eight with copy number variations, and four with chromosome abnormalities. Single nucleotide variations in the 48 patients were classified into syndromic ( n=18, 37.5%), metabolic ( n=16, 33.3%), epileptic ( n=11, 22.9%) and mitochondrial-related genes ( n=3, 6.3%), of which 14 were not included in any database. Among the 103 cases which were successfully followed up until December 31, 2021, 75 (72.8%) had a poor prognosis, including 52 (50.5%) death cases and 23 (22.3%) cases of development retardation. Birth weight and the incidence of seizures in the poor prognosis group were both lower than those in the non-poor prognosis group [(2 876±536) vs (3 254±554) g, t=3.15; 29.3% (22/75) vs 53.6% (15/28), χ2=5.20; both P<0.05], while the incidence of disturbance of consciousness was higher [80.0% (60/75) vs 53.6% (15/28), χ2=7.19, P<0.05]. The proportion of infants with genetic abnormalities in the poor prognosis group was higher than that in the non-poor prognosis group, but the difference was not statistically significant [53.3% (40/75) vs 46.4% (13/28), χ2=0.39, P=0.533]. Conclusions:Genetic abnormality is one of the leading causes of unexplained neonatal encephalopathy. Nucleotide variation is the most common genetic type. Syndromic, metabolic, and epileptic variants are frequently detected in these patients.

ABSTRACT

Objective:To study the risk factors of metabolic bone disease (MBD) associated fracture in very low birth weight premature infants.Methods:From January 2012 to December 2019, premature infants (gestational age <32 weeks, birth weight <1 500 g) were admitted to our hospital and followed-up regularly for 1.5 years (once every month within first 6 months, then once every 3 months). The infants were assigned into two groups according to X-ray diagnosis: the fracture group and the non-fracture group. The clinical data of the two groups were compared and the risk factors of fracture were analyzed.Results:A total of 62 preterm infants with MBD were included in this study, including 11 in the fracture group and 51 in the non-fracture group. The risk factors of MBD associated fracture included intrauterine growth restriction (IUGR), birth weight <1 000 g, gestational age, respiratory support duration and total parenteral nutrition (TPN) duration ( P<0.05). Logistic regression analysis showed that IUGR ( P<0.05, OR=2.159, 95% CI 1.536~2.759) and TPN duration ( P<0.05, OR=1.143, 95% CI 1.042~1.270) were independent risk factors for fracture. Serum alkaline phosphatase (ALP) in the fracture group was significantly higher than the non-fracture group and 25(OH)VitD was significantly lower than the non-fracture group ( P<0.05). Conclusions:IUGR and TPN duration are risk factors for MBD associated fracture in preterm infants. As biochemical markers of bone metabolism, ALP and 25(OH)VitD levels have clinical value predicting MBD associated fracture.

ABSTRACT

Background and Objectives@#Adipose-derived stem cell (ADSC) transplantation improves stem cell paracrine function and can enhance wound healing. However, in diabetic patients, glucose-associated effects on this function and cell survival lead to impaired wound closure, thereby limiting ADSC transplantation efficiency. The hypoxia-inducible factor HIF-1α has an important protective function during wound healing. Here, we aim to clarify the regulatory mechanism of ADSCs. @*Methods@#and Results: ADSCs were isolated from BALB/C mice adipose samples. We then used high-throughput se-quencing to assess abnormal expression of circular RNAs (circRNAs). We also used an in vivo full-thickness skin defect mouse model to assess the effects of transplanted ADSC on diabetic wound closure. Hypoxic pretreatment of ADSCs accelerated diabetic wound closure, which enhanced angiogenic growth factor expression in our mouse model. High-throughput sequencing and RT-qPCR indicated that circ-Gcap14 was upregulated in hypoxic pretreated ADSCs. Similarly, circ-Gcap14 downregulation also decreased the therapeutic effects of ADSCs; however, circ-Gcap14 overexpression increased the effects of ADSC by promoting angiopoiesis. We also used a luciferase reporter assay to confirm that miR-18a-5p and HIF-1α were downstream targets of circ-Gcap14. HIF-1α expression plays an important role in increased VEGF level. @*Conclusions@#Based on our data, we suggest that circ-Gcap14 plays an important role in accelerating hypoxic ADSC-mediated diabetic wound closure, by enhancing mouse angiogenic growth factor expression and regulating downstream miR-18a-5p/HIF-1α expression.

ABSTRACT

Objective To study the clinical features and follow-up of newborns with severe hypoxic-ischemic encephalopathy ( HIE) , and to provide the basis for rational diagnosis, treatment and follow-up.Methods Clinical data of cases of HIE from the Neonatal Department of our Hospital from January 2011 to October 2014 were studied retrospectively. The data of general information, laboratory examination, treatment, outcome, follow-up and prognosis of the patients were collected. Multivariate logistic regression analysis was used to study the influential factors of the prognosis of HIE.Results A total of 123 infants with sever HIE were enrolled in our study. In addition to general therapy, 6 cases were treated with mild hypothermia, and 21 cases were treated with high pressure oxygen. 60 cases improved our treatment, 55 cases had withdrawal treatment with parental consent, and 8 cases died. Single factor analysis showed that 5 minutes Apgar score, convulsions, coma, pH, BE, organ injury, and mild hypothermia treatment were the risk factors that affect the prognosis of severe HIE. Multiple factors analysis showed that 5 min Apgar score <3 points ( OR=4. 071 ,95℅CI 1. 309-15. 613 ) and BE≤-10 mmol/L ( OR=36. 810, 95℅CI 5. 913-41. 119) were independent risk factors of prognosis of severe HIE ( P<0. 05). Hospitalization within the first 72 hours of life ( OR=0. 096, 95℅CI 0. 096-0. 353) was a protective factor of severe HIE. Multiorgan injury ( mainly the injury of brain, lung and heart) and electrolyte imbalance ( mainly hypocalcemia and hyponatremia ) were common complications of serve HIE. In the follow-up of these patients, 33 cases were loss in follow up, and 49 cases died (8 cases died during hospitalization, 41 cases died after withdrawal of treatment). The top five causes of death were abandonment of treatment due to financial reasons and the fear of adverse outcome (n=20), multiple organ dysfunction ( n =16 ) , and pneumothorax ( n =4 ) , diffuse intravascular coagulation (n=6), and shock (n=3). 41 cases survived were followed up for 9~54 months. The critical clinical conditions observed among these infants included cerebral palsy ( n = 5 ) , epilepsy ( n = 3 ) and developmental retardation(n=26).Conclusions There are many complications of severe HIE.The mortality of severe HIE is high, and the incidence of poor outcome of survivors is also high. Timely detection of risk factors is the key to the prevention of severe HIE. Long-term prognosis of severe HIE requires proper organization of neonatal follow up.

ABSTRACT

Purpose To investigate the expression of OTUB1 in colon cancer and the relationship between its expression and some clinicopathologic parameters. Methods Quantitative real-time PCR and immunohistochemical SP method were carried out in selected colon cancer and normal mucosa tissues. Results OTUB1 mRNA in colon cancer was 3. 5-fold higher than the normal mucosa. The expression of OTUB1 protein in the colon cancer was significantly higher than normal mucosa (P<0. 05). Moreover, its expression in normal tissues, adenoma and colon cancer showed a gradually increasing trend (P<0. 05). The higher expression of OTUB1 in colon cancer was related with tumor size, differentiation and lymph node metastasis. Conclusions OTUB1 may play an important role in co-lon cancer development.

ABSTRACT

Objective To investigate the effects of cell proliferation and apoptasis on the develop-ment of gastric mucosal lesion in patients with primary pathological duodena-gastric reflux (DGR). Methods Gastroscopy, histologie examination of gastric mucosal biopsy and 24-hour intra-gastric bilirubin monitoring with Bilitec 2000 were performed in 58 patients with primary pathological DGR. Immunohisto-chemical staining was used to detect the expressions of Ki-67 and Bcl-2 proteins. Cell apoptosis in gastric mucesa was determined by TUNEL technique. Results The proliferating index (PI) and apoptosis index (AI) in patients with primary pathological DGR were significantly higher than those in control group (P< 0.05). The differences of PI and AI between high reflux group and low reflux group were significant (P< 0.05). The incidence difference of chronic superficial gastritis (CSG) and chronic atrophic gastritis (CAG) in gastric antrum between the two groups was significant (P<0.05). With lesion progressing from normal gastric mucosa, CSG, CAG to intestinal metaplasia (IM), PI and AI increased gradually and consistently. PI was still on the rise after dysplasia (Dys), but AI decreased. The positive expression rate of Ki-67 in Dys were significantly higher than that of other groups (P<0.05), so was that of Bcl-2 (P<0.05). Conclusion Cell proliferation and apoptesis may be one aspect of the main pathogenesis of gastric mucesa lesion and cell dysplasia in patients with primary pathological DGR. Over-expreasion of Ki-67 and Bcl-2 proteins in CAG, IM and Dys may play a key role in the development of gastric cancer.

ABSTRACT

Objective To investigate the functional changes of anastomosed vascular or neurovascular mini-muscle transfer and to provide experimental data to clinical application. Methods 32 New Zealand rabbits were operated on by anastomosed neurovascular mini-muscle transfer. In group A, 16 rabbits accepted the anastomosed vascular mini-muscle transfer. In group B, 16 rabbits accepted the anastomosed neurovascular mini-muscle transfer. The electromyography was measured 2 months and 3 months after operation. Results The amplitude of electrical muscle graph (EMG) data in the group A was (2.02±0.41)mV 2 months after operation, and (1.73±0.18) mV 3 months after operation. The EMG data in the group B was (3.90±0.52) mV 2 months after operation and (3.35±0.86) mV 3months after opera-tion. The difference between the two groups was significant (P<0.01). The EMG of anastomosed neu-rovasular mini-muscle transfer was significantly greater than that of anastomosed vasular transfer only.There was no significant difference in latent period of EMG between the two groups (P>0.05). Conclu-sions The muscle functional recovery of anastomosed neurovascular mini-muscle transfer is significant with less demage and no secondary deformity. The results suggest that this technique is worthy to apply for treating facial paralysis.
