Objective To explore the value of three-vessel and trachea(3VT) view plus aortic arch coronal section in ultrasonic diagnosis and classification of fetal right aortic arch(RAA).Methods Echocardiography data and follow-up results of 44 fetuses with RAA were retrospectively analyzed.Sonographic features on 3VT view and aortic arch coronal section were summarized.Results Among 44 fetuses with RAA,27 cases(61.36%) were RAA with aberrant left subclavian artery(ALSA) and the left ductus arteriosus(LDA) connecting the ALSA and U-shaped vascular ring was formed;17 cases(38.64%) were mirror right aortic arch(MRAA).Among 17 cases with MRAA,3 cases were with LDA connecting the descending aorta(DAO) and U-shaped vascular ring was formed;1 case was with LDA connecting the left innominate artery(LINA),8 cases were with absent ductus arteriosus(ADA),5 case were with right ductus arteriosus(RDA),no vascular ring was formed.Parts of MRAA were combined with other complex intracardiac abnormalities.RAA-ALSA-LDA were rarely combined with intracardiac abnormalities.Conclusions 3VT view is simple and intuitive for diagnosing RAA.Aortic arch coronal section has great clinical value in determining the concrete type of RAA.

0. 05). Conclusions Tinnitus is a common problem in the older population. With the aging of population, the problem will become more and more severe. More research is urgently needed on prevention and treatment of tinnitus in elderly people.

OBJECTIVETo examine the effect of aqueous extracts of Scutellaria baicalensis Georgi and Radix paeoniae Alba on periodontitis mice and compare the results of the two herbs for the treatment of the periodontitis mice.

METHODSSixty-four SPF 12-week-old male Kunming mice were selected and randomly divided into four groups:Control group(C); Experimental periodontitis group (P):the peridontitis models in Kunming mice were prepared by wrapping silk ligature and inoculating with putative periodontopathic bacteria; Scutellaria baicalensis Georgi treatment group (SG): periodontitis was induced by the same method described above, the mice were gavaged with Scutellaria baicalensis Georgi; Radix paeoniae Alba treatment group (RG): periodontitis was induced by the same method described above, the mice were gavaged with Radix paeoniae Alba.Four mice were sacrificed at each time point of the end of 4, 6, 8 and 10 weeks in each group. The histopathological changes of periodontal tissue were observed under microscope with HE staining. The level of serum IgG1 and IgG2a was measured by enzyme-linked immunosorbent assay (ELISA) .

RESULTSA serious inflammatory response, alveolar progressive absorption and a large number of osteoclasts were observed in the experimental periodontitis group.However, in SG and RG, the inflammation of the periodontal tissue was decreased and tissue repair was significant. The level of serum IgG2a in SG (6 week:0.934 ± 0.006, 8 week:0.743 ± 0.009, 10 week: 0.674 ± 0.008) and RG (6 week: 1.023 ± 0.032, 8 week: 0.851 ± 0.032, 10 week:0.790 ± 0.009) was significantly decreased after the mice were gavaged with the two herbs(P < 0.01). The level of serum IgG2a in SG was significantly lower than that of RG (P < 0.01). The level of serum IgG1 in SG (6 week: 0.314 ± 0.006, 8 week: 0.344 ± 0.004, 10 week: 0.367 ± 0.006) and RG (6 week: 0.287 ± 0.005, 8 week: 0.303 ± 0.058, 10 week: 0.336 ± 0.006) were significantly increased (P < 0.01). The level of serum IgG1 in SG was significantly higher than that of RG (P < 0.01).

CONCLUSIONSBoth the aqueous extracts of Scutellaria baicalensis Georgi and Radix paeoniae Alba showed therapeutic effect on periodontitis in mice.Scutellaria baicalensis Georgi was more effective than Radix paeoniae Alba.

Objective: This study used cardiac magnetic resonance imaging (MRI) to compare the characteristics of left ventricular remodeling in patients with primary aldosteronism (PA) with those of patients with essential hypertension (EH) and healthy controls (HCs). Materials and Methods: This prospective study enrolled 35 patients with PA, in addition to 35 age- and sex-matched patients with EH, and 35 age- and sex-matched HCs, all of whom underwent comprehensive clinical and cardiac MRI examinations. The analysis of variance was used to detect the differences in the characteristics of left ventricular remodeling among the three groups. Univariable and multivariable linear regression analyses were used to determine the relationships between left ventricular remodeling and the physiological variables. Results: The left ventricular end-diastolic volume index (EDVi) (mean ± standard deviation [SD]: 85.1 ± 13.0 mL/m2 for PA, 75.9 ± 14.3 mL/m2 for EH, and 77.3 ± 12.8 mL/m2 for HC; p = 0.010), left ventricular end-systolic volume index (ESVi) (mean ± SD: 35.2 ± 9.8 mL/m2 for PA, 30.7 ± 8.1 mL/m2 for EH, and 29.5 ± 7.0 mL/m2 for HC; p = 0.013), left ventricular mass index (mean ± SD: 65.8 ± 16.5 g/m2 for PA, 56.9 ± 12.1 g/m2 for EH, and 44.1 ± 8.9 g/m2 for HC; p < 0.001), and native T1 (mean ± SD: 1224 ± 39 ms for PA, 1201 ± 47 ms for EH, and 1200 ± 44 ms for HC; p = 0.041) values were higher in the PA group compared to the EH and HC groups. Multivariable linear regression demonstrated that log (plasma aldosteroneto-renin ratio) was independently correlated with EDVi and ESVi. Plasma aldosterone was independently correlated with native T1. Conclusion Patients with PA showed a greater degree of ventricular hypertrophy and enlargement, as well as myocardial fibrosis, compared to those with EH. Cardiac MRI T1 mapping can detect left ventricular myocardial fibrosis in patients with PA.

Objective To summarize the prenatal ultrasonographic characteristics of anomalous origin of one pulmonary artery from the aorta( AOPA ) ,and describe the diagnostic and clinical outcomes of fetal AOPA . Methods Echocardiographic characteristics of 3 fetuses with AOPA were reviewed . The ultrasonographic features were comparatively analyzed with postpartum autopsy findings . The relevant literature were reviewed and the experience of prenatal diagnosis of AOPA were summarized . Results In 3 cases with AOPA ,2 cases were the proximal type and anomalous origin of right pulmonary artery from the aorta ,of them ,one was accompanied with coarctation of the aorta , the other was accompanied with aortopulmonary window . One case was the distal type and anomalous origin of left pulmonary artery from the left innominate aorta ,it was only associated with mirror right aortic arch and right ductus arteriosus . Ultrasound characteristics were no bifurcation in distal pulmonary artery ,main trunk of pulmonary artery extends directly to one branch ,the other branch originated from the ascending aorta or left innominate artery . Three cases were confirmed by postpartum autopsy . Conclusions There are some characteristic signs on ultrasonic features of AOPA . Prenatal ultrasound has important value for diagnosis of AOPA .

Objective: To discuss the effect of high-density fat-binding SVF-GEL in female facial lipofilling. Methods: This is a retrospective study including 32 female patients, received facial fat transplantation during June 2017 to June 2018 in Yichun College. Each patient underwent high-density fat-binding SVF-GEL transplantation for facial surgery. Patients′satisfaction with the surgery and the rate of secondary surgery was evaluated. Fat was harvested from the inner thigh, centrifuged at 1200 g for 3 min, and the liquid was removed. The upper 2/3 part is prepared for SVF-GEL, for further used in delicate lipofilling in eyelid, tear groove and nasolabial groove. The lower 1/3 high density fat was used for volume restoration, such as forehead, temporal area and cheek. Results: All patients had significant improvements in facial contours with mild swelling and short recovery time. The satisfaction rate was 68.8%(22/32), and the second operation rate was 15.6%(5/32). Conclusions High-density fat-binding SVF-GEL transplantation can achieve good results in correcting facial volume loss.
