Objective:To evaluate the development of fetal cerebral sulci and gyrus and the blood perfusion in pregnant women with gestational diabetes mellitus(GDM) by ultrasound.Methods:A total of 1 540 pregnant women with 28-34 weeks of pregnancy who underwent systematic screening in Henan Provincial People′s Hospital from January 2022 to October 2022 were prospectively selected, 100 pregnant women with GDM were selected as the GDM group. According to the effect of blood glucose control, the GDM group was divided into 2 groups: the satisfied control group (GDM group 1), and the dissatisfied control group (GDM group 2), with 50 cases in each group. At the same period, 50 healthy pregnant women at 28-34 weeks of gestation were enrolled as the control group. The differences of the sylvian fissure, parietooccipital sulci, calcarine sulci and cinguli sulci among the 3 groups were statistically analyzed. And the correlations between the deep of the brain cerebral sulci and gyrus and controlled blood glucose levels were evaluated. The umbilical artery pulsation index(UAPI), middle cerebral artery pulsation index(MCAPI) and ductus venosus pulsation index(DVPI) among the 3 groups were compared, and the differences in fetal blood perfusion among the 3 groups were evaluated.Results:There were no significant differences in the depths of the sylvian fissure, parietooccipital sulci, calcarine sulci and cinguli sulci between the control group and the GDM group 1 (all P>0.05), and they were larger than those of the GDM group 2 (all P<0.05). The depths of lateral fissure, parieto-occipital sulcus, cingulate sulcus and calcarine sulcus were negatively correlated with fasting blood glucose, 1 h and 2 h postprandial blood glucose (all P<0.05). There were no significant differences in MCAPI, UAPI and DVPI between the control group and GDM1 group (all P>0.05). The MCAPI in GDM 2 group was lower than that in the control group and GDM 1 group, and the UAPI and DVPI values were higher than those in the control group and GDM1 group(all P<0.05). Conclusions:The maturity of fetal cerebral sulci and gyrus in GDM pregnant women is related to the blood glucose control of pregnant women. The change of blood perfusion caused by persistent hyperglycemia in pregnant women and intrauterine hypoxia may cause the development retardation of cerebral sulci and gyrus.

Most of the maxillary impacted third molars are located in the maxillary tuberosity,where the vision and op-eration space are limited.This paper reports a case of surgical extraction of the left maxillary horizontal superhigh impact-ed third molar,which is located between the roots of the adjacent teeth and is closely related to the maxillary sinus.The digital simulation technology was used to reconstruct a three-dimensional visual image of the patient's maxilla,related teeth,and other adjacent anatomical structures to assist in finding the optimal surgical method accurately.Root dis-location before the crown not only protects the roots of the adjacent tooth,but also reduces the risk of maxillary sinus lining damage or perforation during operative procedures,improves the efficiency of the operation,and reduces surgical trauma,which conforms to the concept of minimally inva-sive surgery and provides a new idea and experience for the clinical extraction of such maxillary impacted third molars.

The paper summarizes the imaging evaluation methods for assessing the degree of carotid artery stenosis and analyzes the unique advantages and limitations of various imaging techniques in vascular imaging based on existing guidelines and consensus.The paper focuses on reviewing the clinical applications of several novel ultrasound technologies,including the use of advanced hemodynamic parameters such as blood flow dispersion(Tur index)and wall shear stress(WSS).Carotid artery stenosis is closely associated with cardiovascular disease.Although non-invasive and radiation-free ultrasound technology has certain limitations in diagnostic accuracy to a certain extent,with the continuous emergence of advanced functions such as ultrasound hemodynamics and vascular elasticity,the combination of multi-modality and multi-parameter ultrasound is expected to become an important method for efficient diagnosis of arterial stenosis in the future.

Odontoma is a hamartoma or developmental malformation of dental tissues and often causes delayed or im-pacted permanent teeth.This paper reports a case of surgical removal of an odontoma that is closely attached to the labial bone plait and examines the extraction of accompanying high-impacted maxillary canine beside the nose and maxillary sinus.Digital technology was used in reconstructing a part of a patient's maxilla,odontoma,related teeth,and other adja-cent anatomical structures,accurately determine the lesion boundary,and design an optimal surgical plan.The minimally invasive extraction of lesions and embedded teeth with a double-fenestration technique through the upper and lower paths not only preserved the continuity of the labial alveolar bone plate in the operative area and prevented postoperative bone collapse but also reduced the risk of maxillary sinus mucosal injury and perforation,improved surgical efficiency,and reduced the surgical trauma.These features were in line with the concept of minimally invasive alveolar surgery.

Purpose To explore the ultrasound features and early diagnostic clues of fetal myocardial non-compaction.Materials and Methods The clinical data and echocardiographic data of four fetuses who underwent fetal echocardiography in Henan Provincial People's Hospital from January 2015 to February 2023 and were confirmed to have myocardial non-compaction by pathological finding or postnatal examination were collected,and analyzed.Results A total of four fetuses diagnosed as myocardial non-compaction by prenatal ultrasound:two involved the left ventricle with isolated lesions,and apical myocardial non-compaction was confirmed by postnatal echocardiography;two involved the biventricles,and both of which were pathologically confirmed after induction of labor.The prenatal ultrasound of fetal myocardial involvement in four cases showed that:(1)the affected myocardium showed a bilayer structure:the outer layer was compacted myocardium,which showed thin and compacted homogeneous hypoechoic;the inner layer was loose and thickened non-compacted myocardium with enhanced echogenicity;(2)color Doppler flow imaging:the non-compacted myocardium showed sieve mesh blood flow with ventricular communication.Some cases were associated with cardiac enlargement and arrhythmia.Conclusion Prenatal echocardiography can diagnose fetal myocardial non-compaction with a characteristic echographic presentation.Localized myocardial thickening and echogenic enhancement,cardiac enlargement and arrhythmia may be important clues to identify fetal myocardial non-compaction.

Objective To prepare decellularized scaffolds from rabbit cartilage at various concentrations and assess their physicochemical properties and compatibility with stem cells to provide an experimental basis for cartilage repair.Methods Bone marrow mesenchymal stem cells(BMSCs)were cultured using the Percoll density gradient separation method,and this was followed by flow cytometric analysis and testing of their osteogenic and chondrogenic differentiation capabilities.Cartilage pieces were excised from rabbit knees and hip joints and subjected to physical crushing,repeated freeze-thaw cycles,and mixed enzymatic digestion for decellularization.To compare and observe the physicochemical properties of the decellularized scaffolds at different concentrations,three groups of scaffolds(labelwd A,B,and C)were designed with concentrations of 100％,50％and 30％,with three replicates each.Third-generation PKH26-labeled BMSCs were seeded onto optimally concentrated scaffolds and cultured for 1 week to observe cell growth.Results Flow cytometry detected BMSC surface antigens with positive expression of CD44 and CD90 and negative expression of CD45.Osteogenic induction stained with alizarin red showed red calcific nodules,and chondrogenic induction stained with alcian blue showed blue cartilaginous nodules.No apparent cell morphology was observed in the three groups of scaffolds stained with hematoxylin-eosin,and toluidine blue.There was a significant difference in DNA concentration between decellularized samples and non-decellularized scaffolds(P＜0.05).The content of glycosaminoglycans was slightly lower than the normal values.Significant differences were observed between the three groups of scaffolds in terms of pore size,water absorption,porosity,tensile strength,and Young's modulus(P＜0.05).After co-cultivation of stem cells with the scaffolds,cell adhesion was found to be good.Conclusions Percoll density gradient separation can obtain high-purity rabbit BMSCs,and the mixed decellularization method is superior.Group B scaffolds were the most suitable for tissue-engineered cartilage repair.BMSCs cultured in vitro grew well on Group B scaffolds.

Objective:To investigate the normal parameter values of transvaginal E-Cervix cervical elastography of primipara and explore the correlation between E-Cervix parameters and gestational age.Methods:A total of 301 primiparas underwent E-Cervix by transvaginal ultrasound in Henan Provincial People′s Hospital from March 2019 to January 2021, they were divided into 6 groups according to generational weeks: group A (11-13 + 6W), group B (14-17 + 6W), group C (18-21 + 6W), group D (22-25 + 6W), group E (26-29 + 6W), group F (30-33 + 6W). Real-time E-Cervix parameters were obtained, including elasticity contrast index (ECI), hardness ratio (HR), internal ostium (IOS), and external ostium (EOS), strain ratio of the internal and external cervical ostium (IOS/EOS), and the correlations between E-Cervix parameters and the gestational week were analyzed. Results:The normal reference ranges of parameters ECI, IOS, EOS, HR and IOS/EOS were obtained, their 95% reference values in groups A to F were as follows: ECI (1.84-3.38, 2.13-4.50, 2.25-4.12, 2.06-3.96, 2.04-5.15, 2.36-5.53), HR (85.85%-88.72%, 77.31%-80.92%, 74.41%-78.50%, 71.13%-74.35%, 64.49%-68.56%, 63.57%-68.23%), IOS (0.12-0.21, 0.14-0.34, 0.14-0.31, 0.19-0.40, 0.19-0.56, 0.21-0.49), EOS (0.12-0.30, 0.14-0.34, 0.16-0.41, 0.20-0.39, 0.22-0.58, 0.22-0.54), IOS/EOS (0.55-1.12, 0.52-1.45, 0.56-1.26, 0.54-1.38, 0.54-1.52, 0.65-1.46). The differences of ECI, HR, IOS and EOS in different groups were statistically significant (all P<0.05). Spearman correlation analysis results showed that ECI, IOS, and EOS were positively correlated with gestational week( rs=0.524, 0.689, 0.609; all P<0.01). HR was negatively correlated with gestational week ( rs=-0.755, P<0.01). The regression equations of ECI, HR, IOS and EOS were Y=0.06X+ 52.214, Y=99.25-1.07X, Y=8.63E-3X+ 0.05, Y=7.94E-3X+ 0.1, respectively. Conclusions:The normal parameters values of E-TVES are summarized.It provides effective support in data for cervical evaluation in the preterm prediction and success of labor induction.

OBJECTIVES: Hysteroscopic adhesiolysis (HA) remains the mainstay on treatment for intrauterine adhesions (IUA). The fertility outcome of patients with moderate and severe intrauterine adhesions after HA is still far from satisfactory. Estrogen combined with progesterone is the most common treatment; however, they do not help in improving the fertility rate to the maximum because of the limitations. This retrospective, non-randomized controlled study will assess the effects of traditional Chinese medicine Yangmo decoction after HA in restoration of the endometrium and improvement of the fertility rate. METHODS: A total of 427 patients, who met the inclusion criteria, aged between 20 and 45 years and diagnosed with moderate or severe IUA underwent HA at the Third Xiangya Hospital from January to August 2021, were enrolled for this study. Participants were assigned into 2 groups: A Yangmo decoction group (n=213, patients were given Yangmo decoction consisting of Ginseng flower, Sanchi flower, Daidai flower, Snow lotus, Licorice and so on after HA), and an estrogen and progesterone group (n=214, patients were given estrogen and progesterone after HA). The following basic information was collected retrospectively for both groups, including age, parity, history of abortion, menstrual status, and times of hysteroscopic interventions. American Fertility Society (AFS) score was used by a senior surgeon and the density of opening of endometrial glands was evaluated during HA. The parameters were obtained from three-dimensional transvaginal ultrasound (3D-TVUS) preoperatively and postoperatively, to evaluate the efficacy of Yangmo decoction, estrogen, and progesterone. All patients were followed up on telephone to determine the fertility rate until 6 months from the last HA. RESULTS: Based on the basic information collected preoperatively, there were no significant differences between the groups (all P>0.05). Postoperatively, patients in the Yangmo decoction group had a better surgical success rate with a more significant AFS reduction (P<0.001), better density of opening of endometrial glands in the uterine cavity (P<0.000 1) after HA, and a better fertility rate (40.4%) in the time of 6 months after the last HA than those of the estrogen and progesterone group. CONCLUSIONS Yangmo decoction has better therapeutic efficacy in the treatment of intrauterine adhesion after HA than the combined effect of estrogen and progesterone. Yangmo decoction helps restore the endometrium and improve the fertility rate, therefore, it can be adopted as a routine practice for IUA patients who have fertility requirements.
