Objective To observe the effect of 3R therapy on quality of life and subjective well-being in older patients with mild cognitive impairment (MCI). Methods 158 patients with MCI were collected from 8 communities in Ningbo city with Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV as the diagnostic criteria, and assessed by Montreal Cognitive Assessment (MoCA). The experimental group (n=79) was intervened by 3R (Reminiscence, Reality Orientation, Remotivation) for 12 weeks, and the control group (n=79) received no intervention. Their quality of life was assessed with WHO Quality of Life-BREF (WHOQOL-BREF) and the subjective well-being was assessed with Philadelphia Geriatric Center Morale Scale (PGC). Results Their quality of life and subjective well-being improved after intervention in the experimental group (P<0.05), and were better in the experimental group than in the control group (P<0.05). Conclusion 3R therapy could effectively improve the quality of life and subjective well-being in patients with MCI.

【Objective】 To explore the influence of maternal blood donation before pregnancy on neonatal birth weight. 【Methods】 A total of 6 428 full-term (gestational age ≥37 weeks) singleton pregnant women in Ningbo Medical Center Lihuili Hospital and Ningbo Women and Children′s Hospital from January 2020 to October 2020 were enrolled in this study. The cumulative whole blood donations before pregnancy were obtained through Alipay software. The relevant data of parturients and their fetuses were collected from electronic medical records. 【Results】 The maternal blood donation rate in Zhejiang Province before pregnancy was 14.69%. The average age of women was 29 (27-32), and the median of cumulative blood donation (except 0 mL) before pregnancy was 300 mL. Univariate analysis showed that there was no significant difference in neonatal gender, neonatal birth weight, proportion of low birth weight infants and proportion of macrosomia among non blood donation group, low blood donation group and high blood donation group (P>0.05). After multiple linear regression analysis, it was found that there was no correlation between blood donation before pregnancy and the neonatal birth weight (B=0.123, 95%CI: -1.013-8.461, P>0.05). Multivariate Logistic regression analysis showed that, compared with the non blood donation group, the occurrence of macrosomia was higher in both the low blood donation group and the total blood donation group (OR=1.366, 95%CI: 1.007-1.766, P<0.05; OR=1.369, 95%CI: 1.019-1.851, P<0.05). 【Conclusion】 Maternal blood donation before pregnancy may not be related to neonatal birth weight, but may be related to the probability of macrosomia in their offspring.

Congenital entropion, an abnormal condition in which the eyelids roll inward, with the eyelashes losing their normal angulation and tilting toward the eye, especially in the lower eyelids and inner canthus, often occurs in infants and young children. Congenital entropion may lead to corneal epithelial abrasion, inflammation and ulcer, which may affect the function of the eye if not treated in time. Early surgical intervention is helpful to the health of children's eyes. The purpose of surgery is to change the structure of eyelid and weaken the force of entropion, thus improving the symptoms and corneal astigmatism. At present, there are many surgical treatments for congenital entropion. In this paper, the advantages, disadvantages and indications of these treatments are analyzed and summarized, providing a reference for clinical practice.

To investigate the role of glucose transporter 1 (GLUT1) and sodium-glucose cotransporter 1 (SGLT1) in high glucose dialysate-induced peritoneal fibrosis.Thirty six male SD rats were randomly divided into 6 groups (6 in each):normal control group, sham operation group, peritoneal dialysis group (PD group), PD+phloretin group (PD+T group), PD+phlorizin group (PD+Z group), PD+phloretin+phlorizin group (PD+T+Z group). Rat model of uraemia was established using 5/6 nephrotomy, and 2.5% dextrose peritoneal dialysis solution was used in peritoneal dialysis. Peritoneal equilibration test was performed 24 h after dialysis to evaluate transport function of peritoneum in rats; HE staining was used to observe the morphology of peritoneal tissue; and immunohistochemistry was used to detect the expression of GLUT1, SGLT1, TGF-β1 and connective tissue growth factor (CTGF) in peritoneum. Human peritoneal microvascular endothelial cells (HPECs) were divided into 5 groups:normal control group, peritoneal dialysis group (PD group), PD+phloretin group (PD+T group), PD+phlorezin group (PD+Z group), and PD+phloretin+phlorezin group (PD+T+Z group). Real time PCR and Western blotting were used to detect mRNA and protein expressions of GLUT1, SGLT1, TGF-β1, CTGF in peritoneal membrane and HPECs., compared with sham operation group, rats in PD group had thickened peritoneum, higher ultrafiltration volume, and the mRNA and protein expressions of GLUT1, SGLT1, CTGF, TGF-β1 were significantly increased (all<0.05); compared with PD group, thickened peritoneum was attenuated, and the mRNA and protein expressions of GLUT1, SGLT1, CTGF, TGF-β1 were significantly decreased in PD+T, PD+Z and PD+T+Z groups (all<0.05). Pearson's correlation analysis showed that the expressions of GLUT1, SGLT1 in peritoneum were positively correlated with the expressions of TGF-β1 and CTGF (all<0.05)., the mRNA and protein expressions of GLUT1, SGLT1, TGF-β1, CTGF were significantly increased in HPECs of peritoneal dialysis group (all<0.05), and those in PD+T, PD+Z, and PD+T+Z groups were decreased (all<0.05). Pearson's correlation analysis showed that the expressions of GLUT1, SGLT1 in HPECs were positively correlated with the expressions of TGF-β1 and CTGF (all<0.05).High glucose peritoneal dialysis fluid may promote peritoneal fibrosis by upregulating the expressions of GLUT1 and SGLT1.

ObjectiveTo investigate the application value of Toshiba 320-row dynamic volumetric CT angiography in the diagnosis of venous erectile dysfunction (VED).

METHODSWe enrolled in this study 33 patients diagnosed with ED by audiovisual sexual stimulation screening in the outpatient department. Penile erection was induced in the patients by injection of 2 mg phentolamine plus 30 mg papaverine into the corpus cavernosum, followed by that of contrast agent of iobitridol through the vein and corpus cavernosum successively. Then 320-row dynamic volumetric CT angiography was performed and the images of the corpus cavernosum in the arterial and venous phases were collected and processed.

RESULTSDifferent degrees of abnormal venous drainage were observed in 29 of the patients, including 7 cases (24.1%) of back deep venous leakage, 6 cases (20.7%) of foot venous leakage, 3 cases (10.3%) of dorsal superficial venous leakage, 1 case (3.5%) of intervertebral venous leakage, 2 cases (6.9%) of cavernous venous leakage, and 10 cases (34.5%) of mixed venous leakage. Ten of the patients underwent surgery, dorsal deep penile vein ligation in 2 cases, dorsal deep vein embedding plus foot vein ligation in 4, and foot vein ligation in the other 4. Eight of the patients were followed up for 3－12 months post-operatively, during which 2 achieved obvious erectile improvement, while the other 6 gained normal penile erection.

CONCLUSIONSToshiba 320-row dynamic volumetric CT angiography is a reliable method for the diagnosis of VED, which displays the precise location of venous leakage for clinical treatment, with the advantages of clearer images, lower doses of contrast agent and radiation, and faster examination than X-ray penile angiography.

OBJECTIVETo investigate the effects of simvastatin on atherosclerosis and central aortic pressure in ApoE-knockout (ApoE-/-) mice.

METHODSTen 5-week-old male ApoE-/- mice and 5 C57 mice were fed with high-lipid diet for 3 weeks, and then C57 mice (WT group) and 5 ApoE-/- mice (ApoE-/- group) were given 1% carboxymethyl cellulose solution (8 ml·kg-1·d-1), and another 5 ApoE-/- mice (ApoE-/-/S group) were given simvastatin solution (50 mg·kg-1·d-1) by gavege for 3 weeks. The areas of atherosclerotic lesion in aortic root, central aortic pressure and serum lipid levels were examined.

RESULTSNo atherosclerotic plaques were observed in WT group. Compared with ApoE-/- group, simvastatin significantly decreased atherosclerotic lesion area in aortic root (89 818.05±16 980.93 μm2 vs 34 937.01±13 280.65 μm2, P<0.05). The systolic pressure (SP), mean arterial pressure (MAP), pulse pressure (PP) and diastolic pressure (DP) of central aortic pressure were significantly increased in ApoE-/- group compared with those in WT group (P<0.05). Compared to ApoE-/- group, the SP, MAP and PP of central aortic pressure were significantly reduced in ApoE-/-/S group (P<0.05). SP and MAP of central aortic pressure were positively correlated with atherosclerotic lesion area (SP: r=0.7152, P=0.0461; PP: r=0.7594， P=0.0288). Compared with WT group, serum triglyceride, total cholesterol and low-density lipoprotein levels were markedly increased in ApoE-/- group (P<0.05). Serum high-density lipoprotein level was decreased in ApoE-/- group compared with WT group. No differences in serum triglyceride, total cholesterol, low-density lipoprotein and high-density lipoprotein levels were found between ApoE-/- group and ApoE-/-/S group.

CONCLUSIONSimvastatin can attenuate atherosclerosis of aorta in ApoE-/- mice, which is associated with the reduced central aortic systolic pressure but not with the serum lipids levels.

OBJECTIVETo compare the clinical effects of injured vertebra pedicle instrumentation and injured vertebra bone grafting in treating thoracolumbar fractures.

METHODSA retrospective study was performed on 48 patients with single thoracolumbar fractures (type A3) from August 2008 to August 2010. Twenty-four patients were treated with injured vertebra pedicle instrumentation (group A) and 24 were treated with injured vertebra bone grafting (group B). There were 14 males and 10 females with an average age of (44.0 +/- 7.4) years old (34 to 56) in group A and there were 13 males and 11 females with an average age of (42.5 +/- 7.1) years(ranged, 31 to 54) in group B. Operation time, volume of blood loss, complications and the relative parameter of imageology were compared between two groups.

RESULTSThere was no significant difference in gender,age, position of injury, volume of blood loss between two groups. Operation time of group A was shorter than that of group B. Cobb angle and injured vertebral height obviously improved at the immediately postoperatively between two groups; there was no significant difference in group A between the immediately and three months postoperatively, but there was significant difference in group B; there was no significant difference between three months and one year postoperatively in two groups. The failure rate of group B was significantly higher than that of group A.

CONCLUSIONPedicle screw fixation in the injured vertebrae has advantage of short operation time,can obtain satisfactory effects and is better than injured vertebra bone grafting in maintaining the reduction in treating single thoracolumbar fractures.

Astragaloside Ⅳ(AS-Ⅳ) has protective effects against ischemia-reperfusion injury(IRI), but its mechanism of action has not yet been determined. This study aims to investigate the protective effects and mechanism of AS-Ⅳ on H9c2 cardiomyocyte injury induced by hypoxia-reoxygenation(H/R). The H/R model of myocardial cells was established by hypoxic culture for 12 hours and then reoxygenation culture for 8 hours. After AS-Ⅳ treatment, cell viability, the reactive oxygen species(ROS) levels, as well as the content or activity of superoxide dismutase(SOD), malondialdehyde(MDA), interleukin 6(IL-6), and tumor necrosis factor alpha(TNF-α), were measured to evaluate the effect of AS-Ⅳ treatment. The effect of AS-Ⅳ on HO-1 protein expression and nuclear Nrf2 and Bach1 protein expression was determined by Western blot. Finally, siRNA was used to knock down HO-1 gene expression to observe its reversal effect on AS-Ⅳ intervention. The results showed that as compared with the H/R model group, the cell viability was significantly increased(P<0.01), ROS level in the cells, MDA, hs-CRP and TNF-α in cell supernatant and nuclear protein Bach1 expression in the cells were significantly decreased(P<0.01), while SOD content, HO-1 protein expression in cells and expression of nuclear protein Nrf2 were significantly increased(P<0.01) in H/R+AS-Ⅳ group. However, pre-transfection of HO-1 siRNA into H9c2 cells by liposome could partly reverse the above effects of AS-Ⅳ after knocking down the expression of HO-1. This study suggests that AS-Ⅳ has significant protective effect on H/R injury of H9c2 cardiomyocytes, and Nrf2/Bach1/HO-1 signaling pathway may be a key signaling pathway for the effect.

Objective: To evaluate the feasibility and safety of the LAmbre occluder for large-diameter left atrial appendage occlusion. Methods: This study was a retrospective cohort study. Patients with large orifice of the left atrial appendage (≥31 mm) and occlusion with the LAmbre device in the Arrhythmia Center of Ningbo First Hospital were included from June 2018 to March 2020. Baseline data were collected and major perioperative complications of left atrial appendage occlusion (including death, stroke, instrumental embolism, cardiac tamponade, and major bleeding events) were recorded. Patients were followed up 45 days, 6 months and 12 months after surgery. The shunt and device-related thrombosis were recorded by esophageal cardiac ultrasound or pulmonary vein CT, and the occurrence of postoperative thromboembolism, bleeding events, death and other serious adverse events were recorded. Results: The average age and left atrial appendage ostial dimension of 32 patients (37.5% women) included in this research were (70.4±8.4) years old and (34.4±2.9) mm. The LAmbre device was successfully implanted in 31(96.9%) patients. No major complications occurred during the perioperative period. During the 12-month follow-up, pericardial tamponade occurred in 1(3.2%) patient and was recovered after treatment. There was no occluder edge shunt>5 mm in patients followed up by esophageal echocardiography. No significant peri-device leak, device-related thrombus, thromboembolism or death event has occurred. Conclusion: The LAmbre occluder may be feasible and safe for large-diameter left atrial appendage occlusion.
