Objective To investigate the effect of the extracts of Centella asiatica(L.) Urban (ECA) on the depressive-like behavior alteration in rats and mice. Method 60 Wistar rats were randomly divided into 6 groups (10 rats each), the normal group, model group, Fluoxetine group, ECA high dose group (component 10.08 mg+component 24.48 mg/kg), ECA middle dose group (component 1 0.04 mg+component 2 2.24 mg/kg) and ECA low dose group component 1 0.02 mg+component 2 1.12 mg/kg. Chronic unpredictable mild stress (CUMS) induced depression in rats and sugar consumption to detect the antidepressant effect of ECU. 60 Kunming mice were randomly divided into six groups as above. Locomotor activity, forced swim, tail suspension test were used to detect the effect of ECA on the behavioral alteration in mice. Results Compared with model group, sugar consumption in ECA groups was significant increased (P<0.01). ECA treatments also decreased duration of immobility in the tail suspension test and forced swim. Conclusion ECA could improve the depressive-like behavior in rats and mice.

OBJECTIVETo study the relationship between fibrotic focus (FF) and carbonic anhydrase (CA) IX in invasive ductal carcinomas (IDC) of the breast.

METHODSIn 167 cases of IDC, the FF was assessed morphologically, and expression of ER, PR and CA IX was evaluated using MaxVision immunohistochemistry.

RESULTSThe expression of CA IX in IDC with and without FF was 56.3% (45/80) and 28.7% (25/87) respectively, with significant difference (P=0.001). In IDC with FF, the CA IX expression of tumor cells in tumors with CA IX-positive fibroblasts (35/40, 87.5%) was significantly (P<0.001) higher than that in tumors with CA IX-negative fibroblasts (10/40, 25.0%). In IDC with FF, the CA IX expression of fibroblasts of FF in grade 3 IDC (23/33, 69.7%) was significantly (P=0.006) higher than that in grade 1+2 tumors (17/47, 36.2%). The ER and PR expression of tumor cells in tumors containing CA IX-negative fibroblasts was 72.5% (29/40) and 65.0% (26/40) respectively, whereas the ER and PR expression of tumor cells in tumors containing CA IX-positive fibroblasts was 50.0% (20/40) and 42.5% (17/40) respectively; the difference was statistically significant (for both ER and PR, P=0.04). The age of patients with tumors containing CA IX-negative fibroblasts was significantly (P=0.002) older than those containing CA IX-positive fibroblasts. The FF diameter/tumor diameter in tumors containing CA IX-positive fibroblasts was significantly larger than those containing CA IX-negative fibroblasts. (3) For the groups of tumor size≤2 cm and tumor size between 2 cm to 5 cm, the diameter of the fibrotic focus was significantly (P<0.01) smaller than the fibrotic focus size of tumors>5 cm in size.

CONCLUSIONSCA IX expression is correlated with FF, and that in fibroblasts of FF correlated with patients' age, tumor grade, hormone receptors and FF diameter/tumor diameter. CA IX expression in FF might be a marker for poor prognosis in patients with breast cancer.

Objective: To explore the effects of bimodal intervention on the development of auditory and speech ability in the infants with unilateral cochlear implantation(CI). Methods: Total 35 bilateral profound sensorineural hearing loss infants with unilateral CI, aged 0.7 to 2.8 years old, were selected. The subjects were divided into two groups: the group with unilateral CI(cochlear implant alone, n= 15), and the bimodal group with CI and contralateral fitting hearing aid(n= 20). Their auditory and speech abilities were estimated at the different time points after switch-on(the 0th, 0.5th, 1st, 3rd, 6th, 12th, 18th, and 24th month, respectively) using Infant Toddler-Meaningful Auditory Integration Scale(IT-MAIS), Meaningful Use of Speech Scale(MUSS), Categories of Auditory Performance(CAP), and Speech Intelligibility Rating(SIR) scores. Results: The IT-MAIS scores of bimodal group after switch-on were higher than unilateral CI group(the 0.5th, 1st, 3rd, 6th, 12th, and 18th month), the statistical significances were identified at the 0.5th, 1st, 3rd, 6th, and 12th month, respectively(P<0.05). The CAP scores of bimodal group before CI operation and after switch-on(the 0.5th, 1st, 3rd, 6th, 12th, 18th and 24th month)were higher than unilateral CI group, the statistical significances were seen at the 3rd, 6th, 12th, 18th and 24th month after switch-on(P<0.05). The MUSS scores of bimodal group after switch-on were higher than unilateral CI group(the 1st, 3rd, 6th, 12th, 18th and 24th month), the statistical significances were found at the 12th, 18th and 24th month, respectively(P<0.05). The SIR scores of bimodal group after switch-on were higher than unilateral CI group(the 3rd, 6th, 12th, 18th and 24th month), and significant differences appeared at the 12th, 18th and 24th month after switch-on(P<0.05). Conclusion Bimodal intervention could be helpful to the development of auditory and speech ability of infants.

Objective     To summarize the surgical treatment experience in neonates with coarctation of the aorta (CoA) and aortic arch hypoplasia (AAH). Methods     The neonates with CoA and AAH who underwent surgical treatment in the Department of Pediatric Cardiac Surgery of Guangdong Provincial People's Hospital from 2013 to 2020 were retrospectively enrolled. The postoperative complications, long-term survival rate, and freedom from aortic reobstruction were analyzed. Patients undergoing extended end-to-end anastomosis were allocated into an extended end-to-end group, those undergoing extended end-to-side anastomosis into an extended end-to-side group, and those undergoing pulmonary autograft patch aortoplasty into a patch aortoplasty group. Results     Finally 44 patients were  enrolled, including 37 males and 7 females, aged 5.00-30.00 (19.34±7.61) days and weighted 2.00-4.50 (3.30±0.60) kg. There were 19 patients of extended end-to-end anastomosis, 19 patients of extended end-to-side anastomosis, and 6 patients of pulmonary autograft patch aortoplasty. The mean values of the Z scores of the proximal, distal, and isthmus of the aortic arch were –2.91±1.52, –3.40±1.30, and –4.04±1.98, respectively. The mean follow-up time was 45.6±3.7 months. There were 2 early deaths and no late deaths. Aortic reobstruction occurred in 8 patients, and 3 patients underwent reoperation intervention. The 5-year rate of freedom from reobstruction was 78.8%. The Cox multivariable regression analysis showed that the related factors for postoperative reobstruction were the Z score of the preoperative proximal aortic arch (HR=0.152, 95%CI 0.038-0.601, P=0.007) and the postoperative left main bronchus compression (HR=15.261, 95%CI 1.104-210.978, P=0.042). Conclusion     Three surgical procedures for neonates with CoA and AAH are safe and effective, but the aortic reobstruction rate in long term is not low. The smaller Z score of the preoperative proximal aortic arch and the postoperative left main bronchus compression are risk factors for long-term aortic reobstruction.
