Objective To improve the understanding to transposition of the great arteries with posterior aorta and decrease the clinic misdiagnosis by summarizing their echocardiography features . Methods Echocardiography images were retrospectively reviewed for 7 cases with transposition of the great arteries with posterior aorta who diagnosed in Anzhen Hospital ,and their echocardiography features were summarized .Results In 7 patients ,5 patients had operation ,including 3 for arterial switch operation ,1 for right GLEEN ,1 for right GLEEN and Fortan surgery ,and 2 patients were lost to follow‐up .The echocardiography characters:① Artery short view showed aorta and pulmonary artery existed the half‐surrounding relationship .The aorta was situated posteriorly and the pulmonary artery anteriorly .②Multiple views showed aorta was completely and mostly arised from the right ventricle ,while the pulmonary artery was came off the left ventricle .③ Ventricular septal defects were presented in all cases and aorta could ride the defect of ventricular septal .④ In most cases ,fibrous continuity between the aortic and mitral valve through a ventricular septal defect was found and there was no conus under the aorta .⑤ Some cases could combine the different degree stenosis of the outflow tract of subpulmonary valve and pulmonary valve . Conclusions The connection relationship between two arteries and ventricles can displayed clearly on the long axis view of double outflow tracts of two ventricles under xiphoid process .The acoustic window under the xiphoid process is the key for diagnosis and differential diagnosis of the disease .

BACKGROUND:Previous researches have focused on the effect of phosphorus compounds on stem cels from animals or from human. But there is no study on the effect of phosphorus ions on human bone marrow mesenchymal stem cels under three-dimensional culture. OBJECTIVE:To explore the effect of phosphorus ions on human bone marrow mesenchymal stem cels under three-dimensional culture. METHODS:There were six groups in the experiment. Human bone marrow mesenchymal stem cels were inoculated in three-dimensional polystyrene scaffolds and then subjected to serum-free growth medium (group 3-GM) or serum-free growth medium containing 4 mmol/L (group 3-4P), 8 mmol/L (group 3-8P) phosphorus ions for 21 days, respectively. Cels cultured on the two-dimensional polystyrene scaffolds were used as control groups (groups 2-GM, 2-4P, 2-8P). Celular proliferation was examined by cel counting kit-8; the mRNA expressions of osteogenic marker genes were assessed by RT-PCR; the formation of mineralized nodules for the osteogenic differentiation of human bone marrow mesenchymal stem cels was examined by Alizarin red staining. RESULTS AND CONCLUSION:Compared with the two-dimensional culture, the growth of human bone marrow mesenchymal stem cels induced by phosphorus ions were more obvious in the three-dimensional polystyrenes scaffolds at days 4, 7, 14 and 21 (P < 0.05). Compared with the group 3-GM, the mRNA expression of colagen type I in groups 3-4P and 3-8P increased more significantly at days 7 and 14 (P < 0.05); the mRNA expression of alkaline phosphatase in groups 3-4P and 3-8P increased more significantly at day 14 (P < 0.05); the mRNA expression of osteocalcin in groups 3-4P and 3-8P increased more significantly at days 14 and 21 (P < 0.05). Mineralized nodules were formed in groups 3-4P and 3-8P but not in group 3-GM at day 21. So we concluded that phosphorus ions can promote proliferation and osteogenic differentiation of human bone marrow mesenchymal stem cels in three-dimensional polystyrenes scaffolds. Compared with the two-dimensional cel culture, the promoting growth effect of phosphorus ions on human bone marrow mesenchymal stem cels in three dimensional polystyrenes scaffolds are more obvious.

Objective To use evidence-based nursing on patients with artificial airway to the practice of stomach tube, and to evaluate the self made guidance for difficult gastric tube placement in patients with artificial airway.Methods Forty patients with artificial airway and were difficult to put the tube, and admitted to Department of Critical Care Medicine of Harrison International Peace Hospital Affiliated to Hebei Medical University from April to December in 2016 were enrolled as observation group. Through the evidence-based nursing strategy, the related literatures at home and abroad were collected to search clinical evidence and formulate and implement the nursing program, the gastric tube was inserted into the stomach tube under the direct vision of the laryngoscope. Thirty-six patients of difficult gastric tube placement with artificial airway straightly under the direct vision of the laryngoscope from August 2015 to March 2016 were retrospectively analyzed as the control group. The success rate of first catheterization, indwelling time, throat edema and bleeding of pharyngeal mucosa were compared between the two groups.Results All patients were enrolled in the final analysis. In the control group, 28 patients were successfully placed once, while 8 failed. Only 1 patient in observation group failed to catheterize, and successful placed after symptomatic treatment, the one-time success rate of catheter was significantly higher than that of control group (97.5% vs. 77.8%), and catheter time was significantly shortened (minutes: 4.8±1.2 vs. 5.1±1.0), the difference was statistically significant (bothP < 0.05). There were 2 patients with laryngeal edema in the control group and 4 patients of pharyngeal mucosal hemorrhage. In the observation group, there was no laryngealedema and laryngeal edema occurred in the patients with laryngoscopy, and only 1 patient had a hemorrhage of pharyngeal mucosa.Conclusion Using self made guiding device can effectively insert the difficult gastric tube in patients with artificial airway, and increase the one-time success rate of intubation, shorten the catheter time, and have a trend in reduce complication as compared with traditional gastric tube placement.

Objective To improve the prenatal echocardiographic diagnostic accuracy for fetus with isolated mirror-image right aortic arch which combined with vascular ring by analyzing and accumulating its echocardiographic features.Methods Echocardiographic signs were analyzed retrospectively and fetal echocardiographic features were accumulated in 16 cases with prenatal diagnosis of isolated mirror-image right aortic arch with left-side ductus arteriosus which formed vascular ring between January 2014 and February 2016.All cases were confirmed by neonatal echocardiography.Results The fetal echocardiography characters:① In 3-vessel and trachea view,fetal right aortic arch was demonstrated a Ushaped appearance of the great vessels,the right arm of the ‘ U’ represented the aortic arch and its left branch with ductal continuation.② In 3-vessel and trachea view or upper axial mediastinal transverse view,left innominate artery passed straightly to the left of the trachea.Left innominate artery and right-side ductus arteriosus were overlapped and the distance of two vessels was very close.③ In double arch view and longitudinal view for ductus,Left innominate artery did not connect to descending aorta or ductus arteriosus and did not involve in the formation of vascular ring.④ Color Doppler played an important role in diagnosis of this disease.Power Doppler or high-definition imaging easily showed color overflow and wrongly displayed the crossed relationship of left innominate artery with descending aorta as the anatomical connection,and caused the misdiagnosis of this disease as double aortic arch.Conclusions Isolated mirrorimage right aortic arch with vascular ring is not rare in the fetal period.Because ductus arteriosus is large and patent during the prenatal period,it is easily mistaken for the crossed relationship of left innominate artery with descending aorta as the anatomical connection and finally misdiagnoses this anomaly as double aortic arch.The keys to accurate diagnosis of the disease are clearly visualization of the innominate artery and its relationship with descending aorta and ductus arteriosus by scanning different views.

Objective To observe the influence of two feeding ways m coma patients at gastrointestinal tract complications.Methods Seventy patients were assigned randomly to two groups according to different feeding ways:entogastric continuing infusion (observation group,n=35) and entogastric manualinfusion (control group,n=35) from June 2006 to May 2007,and observed the ratio of gastrointestinal tract complications in two groups.Results Different feeding ways had significantly correlated with the complications of gastrointestinal tract.The ratio of gastrointestinal tract complications in observation group was lower (20.00%)than that in control group (42.86%).There was statistically significant difference in two groups,P＜0.05.Conclusion The ratio of gastrointestinal tract complications could obvious reduce in entogastric nutrition continuing infusion in coma patients.

Objective To explore the association between interpregnancy weight change and the recurrence of gestational diabetes mellitus(GDM).Methods This study included women who had two delivery records and a history of GDM during their previous pregnancy at the Guangdong Women and Children Hospital between January 2017 and July 2022.Interpregnancy weight change was defined as the difference between the prepregnancy BMIs of two consecutive pregnancies.Interpregnancy weight change was categorized into four groups(＜-1,-1 to＜1,1 to＜3,≥3 kg/m2),with the-1 to＜1 kg/m2 group serving as the reference.Logistic regression analyses were used to assess the associations of interpregnancy weight changes with GDM recurrence and changes in glucose values during two consecutive pregnancies.Results Among 703 participants,326 individuals(46.4％)experienced GDM recurrence.Compared with the groups with an interpregnancy BMI change of-1 to＜1 kg/m2,the groups with a BMI change of 1 to＜3 or ≥3 presented an increased risk of GDM recurrence,with odds ratio(OR)[95％confi-dence intervals(CI)]of 2.16(1.52-3.08)and 2.56(1.44-4.56),respectively.The risk of GDM recurrence significantly in-creased with increasing interpregnancy weight gain(P for trend＜0.01).However,there was no significant association between a BMI change＜-1 kg/m2 and GDM recurrence,with an OR(95％CI)of 0.95(0.57-1.57).An increase of 1 kg/m2 in the in-terpregnancy BMI was associated with a higher risk of elevated fasting blood glucose and 1 h plasma glucose,with OR(95％C1)of 1.15(1.05-1.26)and 1.21(1.10-1.33),respectively.Conclusion Women with a history of GDM are at a high risk of GDM recurrence,and interpregnancy weight gain is associated with an increased risk of GDM recurrence.These findings under-score the importance of health education among women with a history of GDM who plan to conceive again and emphasize the im-portance of weight management in reducing the recurrence of GDM.

Cognitive dysfunction often coexists with age-related neurodegenerative diseases, leading to decline in the quality of life of individuals and bringing burden on families and society. Myelin sheath is one of the important structures of neurons, and myelin damage can be seen in patients with cognitive dysfunction resulting from neurodegenerative diseases. Early intervention of myelin damage, such as promoting OLs differentiation and miRNA-based therapy, can help pro-myelin remodeling, thereby improve cognitive dysfunction and reduce incidence of cognitive dysfunction in neurodegenerative diseases. This article reviews the recent advance in relationship between myelin injury and cognitive function, and pro-myelin remodeling in improveing cognitive dysfunction, in order to provide references for treatment of cognitive dysfunction.

Objective To analyze the echocardiography features of unilateral absence of pulmonary artery ( U APA ) features and improve the prenatal diagnosis accuracy of U APA by analyzing fetal echocardiography features . Methods Fetal echocardiographic features were analyzed retrospectively in 6 cases with prenatal diagnosis of U APA between June 2012 and October 2018 . A t the same time ,ultrasonic manifestations of 3 patients whose antenatal examinations were performed in other hospitals and diagnosed as UAPA in our hospital were retrospectively analyzed . T he fetal echocardiography characteristics of UAPA were summarized . Results Among the 6 fetuses with UAPA ,4 cases were diagnosed as isolated unilateral absence of proximal right pulmonary artery ,1 was unilateral absence of proximal left pulmonary artery with tetralogy of Fallot ( T O F ) and 1 was isolated unilateral absence of proximal left pulmonary artery . Characteristic sonographical findings included : ① When other intracardiac abnormalities were absent ,the inner diameter and proportion of the heart cavity was normal . ② M ulti‐view showed that the normal confluence structure disappeared at the branch of the main pulmonary artery ,and the diameter of normal pulmonary artery branch was widened . ③On the basis of three vessels and trachea view ( 3V T ) ,moved the probe up and dow n to make a transverse scan ,two‐dimensional and color Doppler flow imaging ( CDFI ) showed a large vessel ( the brachiocephalic trunk artery ) originating from the aortic arch w hich had dual vascular features ,it means that it was difficult to distinguish the pulmonary artery branch from the aortic branch . ④ On coronal view of the large vessel ,two‐dimensional and CDFI clearly showed that the large vessel originating from the aortic arch was the brachiocephalic trunk artery ,and the pulmonary artery branch connected with the brachiocephalic trunk artery by the ipsilateral vertical arterial duct ( DA ) which originated from the root of brachiocephalic trunk artery ,but the left pulmonary artery branch connected with the ventral side of the aortic arch by the left DA in UAPA fetus with T O F . ⑤Spectrum Doppler of the anomalous vessels of the lungs confirmed that it was the pulmonary artery ,and the blood flow of the anomalous PA branch was isolated and no exact connection with the main pulmonary artery . Conclusions U APA can be accurately diagnosed prenatally by echocardiography . T he brachiocephalic trunk artery coronary view is very important for the diagnosis of this disease .Early diagnosis plays an important role in prenatal counseling and prognosis assessment .

Objective To improve the prenatal diagnosis and differential diagnosis ability for anomalous origin of one pulmonary artery branch from the aorta ( AOPA ) and unilateral absence of pulmonary artery ( U APA ) by comparing and analyzing different types of fetal echocardiography features . Methods Fetal echocardiographic features were analyzed retrospectively in fetus with prenatal diagnosis of U APA or AO PA between June 2012 and December 2018 ,and the different types of fetal echocardiography characteristics and main points of identification were summarized . Results A total of 6 fetuses with AOPA and 6 fetuses with U APA were diagnosed .Among the 6 fetuses with AOPA ,5 cases were anomalous origin of right pulmonary artery from the aorta ( AORPA ) ,including 3 cases with isolated AORPA and 2 cases combined with Berry syndrome ,and 1 case was anomalous origin of left pulmonary artery from the aorta ( AOLPA ) with an absent pulmonary valve . All 6 cases of AOPA had proximal form . Among the 6 fetuses with U APA ,4 cases were isolated unilateral absence of right pulmonary artery ,1 case was isolated unilateral absence of left pulmonary artery and 1 case was unilateral absence of left pulmonary artery combined with tetralogy of Fallot ( T OF) . T he main common characteristic sonographical findings included :there was no confluence at the bifurcation of the main pulmonary artery on multiple view s ,and the affected pulmonary branch was not attached to the main pulmonary artery . T he different characteristic sonographical findings in fetus included :the affected pulmonary artery of AO PA arosed from the right posterior or left posterior portion of the ascending aorta on three vessels and trachea view ( 3V T ) and long axial view of left ventricle , and 3V T and the coronary view of brachiocephalic trunk artery showed that the abnormal origin of pulmonary artery branch of U APA connected with the root of brachiocephalic trunk artery by the ipsilateral vertical arterial duct ( DA ) ,and color Doppler flow imaging showed that the blood flow of the affected pulmonary artery branch was isolated in the pulmonary field . Conclusions AOPA and UAPA have many similarities in the characteristics of fetal echocardiography . 3V T and long axial view of left ventricle are the best view s for displaying proximal AOPA ,3VT and the coronary view s of the root of brachiocephalic trunk artery are the best view s for displaying UAPA .
