Objective: To investigate the mortality and disease burden of diabetes in Hangzhou City from 2013 to 2021, so as to provide insights into improving diabetes prevention and control strategies. Methods: Data on morbidity and mortality of diabetes in Hangzhou City from 2013 to 2021 were collected through the Chronic Disease and Death Cause Monitoring System of Hangzhou Center for Disease Control and Prevention, and the crude and age-standardized mortality (standardized by the population of the Seventh National Population Census in China in 2020) were calculated. Data on the prevalence of diabetes were collected from the China Chronic Disease and Risk Factors Surveillance (CCDRFS), and the burden of disease was evaluated by calculating years of life lost (YLL), years lived with disability (YLD) and disability-adjusted years (DALY) with reference to the methodology of the Global Burden of Disease Study (GBD). The trends in mortality and disease burden of diabetes were evaluated with the average annual percent change (AAPC). Results: There were 8 686 deaths of diabetes in Hangzhou City from 2013 to 2021, with the average annual crude mortality of 13.17/105 and age-standardized mortality of 10.89/105. The crude mortality of diabetes showed a tendency towards a rise (AAPC=2.62%, P<0.05), while the trend in age-standardized mortality was not significant (P>0.05). The crude and age-standardized mortality of diabetes were higher in women than in men (14.11/105 vs. 12.21/105, 12.16/105 vs. 9.71/105; both P<0.05); however, the crude mortality in men increased more rapidly (men: AAPC=4.46%, P<0.05; women: AAPC=1.09%, P>0.05). The YLL, YLD and DALY of diabetes were 155.42, 1 246.73 and 1 402.15 thousand person-years, and the rates of YLL, YLD and DALY were 2.36, 18.90 and 21.25 person-years per thousand, respectively. The rates of YLL, YLD and DALY appeared a tendency towards a rise (AAPC=1.57%, 6.03% and 7.11%, all P<0.05). Higher rates of DALY and more remarkable increase were seen in men than in women (P<0.05; AAPC=8.37%, 5.54%, both P<0.05). Conclusions The mortality of diabetes in Hangzhou City from 2013 to 2021 is high, and the burden of disease, especially disability, is growing rapidly, with the burden of disease being more serious in men.

Objective    To evaluate the mid-term safety, efficacy and feasibility of perventricular device closure for subarterial ventricular septal defect. Methods    Clinical data of 97 patients diagnosed with subarterial ventricular septal defect through echocardiography in West China Hospital from September 2013 to December 2015 were retrospectively analyzed. There were 66 males and 31 females aged 3 (1.8, 5.9) years. All the patients underwent perventricular device closure under the guidance of transesophageal echocardiography using eccentric occlusion device. Possible complications such as residual shunt, valvular regurgitation, atrioventricular conduction block and arrhythmias were recorded during the 1-year, 3-year and 5-year follow-up. Results    All the patients received perventricular device closure successfully except that 1 patient underwent open surgical repair under cardiopulmonary bypass 3 months later because of the migration of device. So the rate of complete closure was 99.0%. No residual shunt, moderate or severe valvular regurgitation, atrioventricular conduction block or arrhythmias were observed 5 years later. Conclusion    Treating subarterial ventricular septal defect through perventricular device closure exhibits remarkable mid-term efficacy, safety and feasibility with high success rate.

Objective To investigate whether embolization surgery can improve mid-to-long-term outcomes related to quality of life,anxiety and depression in patients with unruptured intracranial aneurysms(UIA).Methods This prospective study included patients diagnosed with UIA within 30 days.Patients were divided into two groups based on treatment:the embolization group and the conservative group.The assessments of quality of life,depression,and anxiety were conducted using the medical outcome study short form-36(SF-36),self-rating depression scale(SDS),and self-rating anxiety scale(SAS)at baseline,3 months,and 5 years after treatment.In the embolization group,psychological trauma was assessed using the impact of event scale-revised(IES-R)at 3 months and 5 years post-surgery.Results A total of 113 patients were involved in the analysis including 76 in the embolization group and 37 in the conservative group.Compared to the conservative group,SF-36 data showed that the embolization group had a lower physical function(80.3±16.4 vs.86.1±12.8,P=0.046)and role-physical(47.37±43.32 vs.67.57±34.29,P=0.015)scores at 3 months,but a higher mental health score(68.16±18.80 vs.61.62±14.62,P=0.048).At 5 years,all dimensions of SF-36 improved significantly compared to baseline(all P<0.05).The SDS and SAS scores in the embolization group were significantly lower at both 3 months and 5 years compared to baseline(both P<0.05).The decrease in SDS(-2.8±10.6 vs.0.5±6.5)and SAS(-2.7±11.8 vs.1.2±5.4)scores in the embolization group at 3 months was greater than in the conservative group(both P<0.05).Subgroup analysis showed that patients with depression or anxiety at baseline in the embolization group experienced a significant decrease in SDS and SAS scores at 3 months and 5 years compared to baseline(both P<0.05).Additionally,in the embolization group,the IES-R score at 3 months was 37.5±13.8,which was significantly higher than the critical threshold(P=0.005),but decreased to 33.8±13.3 at 5 years post-surgery.Conclusions Patients with unruptured intracranial aneurysms experienced long-term improvements in quality of life after embolization surgery.Embolization surgery also helped alleviate depression and anxiety.

Objective:To investigate the clinical characteristics and prognosis of cytomegalovirus-sepsis-like syndrome (CMV-SLS) in premature infants, and to provide the evidence for early clinical identification and treatment.Methods:Premature infants with CMV-SLS admitted to Children′s Hospital Affiliated of Zhengzhou University from January 1, 2019 to December 31, 2022 were selected as the research subjects, and their clinical characteristics, treatment, and prognosis were retrospectively analyzed.Results:A total of seven cases of CMV-SLS were included, with a gestational age of (26.8±1.2) weeks and a birth weight of (890±121) g. The age of disease onset was 55(45, 60) days, and the age of diagnosis was 67(56, 71) days. All the seven cases were exclusively breast feeding after birth, and cytomegalovirus (CMV) DNA was detected positive in their breast milk when diagnosed with CMV-SLS. The common clinical features were fever, abdominal distension, liver function damage, decreased neutrophil and platelet counts. Pneumonia, neonatal necrotizing enterocolitis, hearing loss, and chorioretinitis were common. After the diagnosis was confirmed, all the seven cases were given intravenous treatment of ganciclovir and followed by oral formulations, with a course of treatment ranging from five to seven weeks. Two cases were treated with intravitreal injection of ganciclovir for chorioretinitis. All the seven cases survived. During the follow-up with a corrected gestational age of 12 months, one case had delayed intellectual and motor development, two cases had delayed motor development, and the remaining cases had normal development.Conclusions:CMV-SLS in premature infants mainly occurs in extremely low birth weight infants, with atypical clinical manifestations and may be misdiagnosed easily. If extremely low birth weight infants who receive CMV DNA positive breast feeding show sepsis-like symptoms, the possibility of CMV infection should be considered, and early diagnosis and treatment should be carried out to prevent adverse outcomes.

Objective    To explore the mechanism of volume-related mitral regurgitation (MR) from the anatomy of mitral valve. Methods    A total of 32 patients with ventricular septal defect (VSD) combined MR meeting inclusion criteria in West China Hospital from September 2018 to November 2019 were enrolled in this study. The direction relative to the cardiac axis: the deviation of the MR bundle along the left atrial wall was eccentric, otherwises it was central. There were 23 patients of VSD and eccentric MR (EMR, a VSD-EMR group), including 10 males and 13 females aged 21 (10, 56) months, and 9 patients of VSD and central MR (CMR, a VSD-CMR group), including 4 males and 5 females aged 26 (12, 87) months. Besides, 9 healthy children were enrolled in a control group, including 4 males and 5 females aged 49 (15, 72) months. All patients underwent transthoracic echocardiography (TTE) examination at 2 weeks before surgery and 6 months after surgery, respectively, The MR degree, end-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV), ejection fraction (EF), antero-posterior diameter (AP), annulus circumference (AC), commissural diameter (CD) were assessed. Results    Before operation, EDV, ESV, SV, AP, AC and CD in the VSD-EMR and VSD-CMR groups were significantly larger or longer than those in the control group (P<0.05); after operation, EDV, ESV, SV, AP and CD decreased compared with those before operation (P<0.05), but there was no significant difference compared with the control group (P>0.05). Compared with the control group, AC was slightly decreased (P<0.05). There was no significant difference in EF between and within groups before and after operation (P>0.05). The improvement rate of MR was 78.9%(15/19) in the VSD-EMR group and 100.0% (9/9) in the VSD-CMR group. Conclusion    After unloading of volume, the valve structure is back to normal except AC. The improvement rate of MR in the VSD-EMR group is lower than that in the VSD-CMR group, which may indicate that the mechanism of VSD-EMR is more complicated.
