Résumé

Objective@# To investigate the trends in incidence and mortality of stroke in Ningbo City, Zhejiang Province from 2012 to 2021, so as to provide the evidence for improving the stroke control strategy in Ningbo City.@*Methods@# Data pertaining to the stroke incidence and mortality in Ningbo City from 2012 to 2021 were captured from Ningbo Municipal Chronic Disease Collaborative Management System, and the incidence and mortality of stroke was estimated and standardized by the Sixth National Population Census in 2010. The trends in incidence and mortality of stroke were evaluated using annual percent change (APC) in Ningbo City from 2012 to 2021. @*Results@# A total of 185 747 residents with stroke were reported in Ningbo City from 2012 to 2021. The crude incidence of stroke was 312.78/105 in Ningbo City from 2012 to 2021, which appeared a tendency towards a rise (APC=2.429%, t=5.507, P<0.001), and the standardized incidence of stroke was 188.86/105, with no remarkable changes seen (APC=-0.399%, t=-1.544, P=0.161). There were 47 355 deaths due to stroke in Ningbo City from 2012 to 2021, and the crude and standardized mortality rates were 79.74/105 and 42.79/105, which both appeared a tendency towards a decline (APC=-4.778%, t=-6.867, P<0.001; APC=-8.269%, t=-13.729, P<0.001). Higher standardized incidence and mortality were seen among men (226.05/105 and 50.14/105) than among women (153.37/105 and 35.89/105), and the crude incidence and mortality of stroke appeared a tendency towards a rise with age (χ2trend=3 671.325, 1 419.107, both P<0.001). The standardized incidence and mortality of hemorrhagic stroke were 40.38/105 and 18.56/105, both showing a tendency towards a decline (APC=-5.042%, t=-12.958, P<0.001; APC=-11.570%, t=-14.979, P<0.001), and the standardized incidence of ischemic stroke was 143.91/105, appearing a tendency towards a rise (APC=1.254%, t=3.223, P=0.012), while the standardized mortality of ischemic stroke was 19.65/105, with no obvious changes seen (APC=-2.110%, t=-2.150, P=0.064). @* Conclusions@# The incidence of stroke appeared a tendency towards a rise and the mortality appeared a tendency towards a decline in Ningbo City from 2012 to 2021. Men and the elderly are at high risk of stroke.

Résumé

Objective@#To explore the associations of Hand-Foot-Mouth disease (HFM) among children of different age groups in kindergartens, and to provide scientific evidence for HFM prevention and control.@*Methods@#Cluster sampling was used to select 9 912 children from 40 kindergartens. The major caregivers of children were invited to participate into the study and fulfill a self-administered questionnaire that consisted of general background, hand washing and the history of HFM among children in the recent 1 year. Chi-square and binary logistic regression were applied,to analyze the influencing factors of HFM among children of different age groups.@*Results@#In the 2 year-old-group, children who were male (OR=1.76, 95%CI=1.24-2.50), had the major caregiver with high school educational background or below (OR=1.54, 95%CI=1.06-2.24), had family income more than 100 000 yuan or more per year(OR=1.49, 95%CI=1.01-2.20), children whose major caregiver seldom wash hands immediately after coming home(OR=2.10, 95%CI=1.05-4.19),and 3-5 times per week(OR=2.07, 95%CI=1.26-3.41) were more likely to have HFM. In the 3 year-old-group, the more time children spent in the outdoors, the less likely they got HFM(3-5 times per week: OR=0.58, 95%CI=0.43-0.81; ≥6 times per week: OR=0.45, 95%CI=0.29-0.70). Children whose major caregiver did not use soap were more likely to have HFM(OR=1.67, 95%CI=1.11-2.49). In the 4 year-old-group, children who occasionally took toys when going out were less likely to get HFM (vs always, OR=0.57, 95%CI=0.38-0.88). No significant factors were found in the 5 year-old-group.@*Conclusion@#The behaviors and activities of major caregivers and children could influence the HFM incidence.To prevent HFM, it was advised that the major caregivers should wash hands immediately after coming home, and develop the habit of using soap for handwashing together with children at the earlier age, and encourage children to take more outside-door activities according to the age characteristics. Attention should be paid to avoid contaminating takeout snacks, and to clean the takeout toys timely.

Résumé

Objective To observe the effect of transcranial direct current stimulation (tDCS) with mirror neuronal rehabilitation training system (MNST-V1.0) in post-traumatic unconscious patients after severe craniocerebral injury. Methods A prospective, self controlled and open-label method was used. Thirty-six post-traumatic unconscious patients with severe craniocerebral injury from January 2016 to July 2017 were selected. Four cases of the patients did not complete the treatment and the last 32 cases completed the study. All patients were given routine wake-up therapy, and tDCS combined with MNST-V1.0 (20 min/time, 1 time/d, 6 times/week, a total of 8 weeks) was given at the same time. The Glasgow coma scale (GCS), JFK coma recovery scale and Four coma rating scale before treatment and 2, 4, 8 weeks after treatment were recorded. Results The scores of open reaction, language and motor response score of GCS 2, 4, 8 weeks after treatment were significantly higher than those before treatment:(1.56 ± 0.82), (2.06 ± 1.01) and (3.11 ± 1.45) scores vs. (1.00 ± 0.45) scores, (2.23 ± 1.06), (2.56 ± 1.08) and (3.02 ± 1.04) scores vs. (1.00 ± 0.61) scores, (2.79 ± 1.12), (3.22 ± 1.33) and (4.44 ± 1.07) scores vs. (1.00 ± 0.54) scores, and there were statistical differences (P < 0.01 or <0.05). The scores of hearing, vision, movement, speech response, communication and arousal of JFK coma recovery scale 2, 4, 8 weeks after treatment were significantly higher than those before treatment, and there were statistical differences (P<0.01). The scores of open reaction, sport reaction, brainstem response of Four coma rating scale 2, 4, 8 weeks after treatment were significantly higher than those before treatment, and there were statistical differences (P<0.05); there was no statistical difference in respiratory score of Four coma rating scale before and after treatment (P>0.05). Conclusions The tDCS combined with MNST-V1.0 can improve the consciousness level in post-traumatic unconscious patients with severe craniocerebral injury, and have the effect of promoting awakening.

Résumé

Objective To investigate the influence of earlier renal fibrosis on ischemia and reperfusion induced acute kidney injury. Methods Male C57BL/6 mice at eight to twelve weeks old age were divided into 4 groups randomly: (1)Sham (n=3); (2)Unilateral ureter obstruction (UUO, n=6):UUO for 3 days (UUO3d, n=3) and UUO for 5 days (UUO5d, n=3);(3)Ischemia and reperfusion (IR, n=7): bilateral kidney ischemia for 40 minutes followed by 24 hours of reperfusion; (4)UUO for 3 days plus IR (UUO3d+IR, n=6): bilateral kidney ischemia after UUO 2 days for 40 minutes followed by 24 hours of reperfusion, and the real time for UUO was 3 days. Pathologic analysis for acute or chronic injury was performed on paraffin embedded kidney sections with hematoxylin and eosin (HE) or Masson staining. Apoptosis was detected by immunohistochemistry(IHC) and Western blotting with anti-caspase-3 antibody, and proliferation was observed by IHC with anti-ki67 antibody. Results On kidney sections with HE or Masson staining, it showed that the chronic kidney lesions and fibrosis got more severe as time of UUO prolonged from 3 days to 5 days; the area of matrix deposition increased in UUO5d and UUO3d mice significantly compared to Sham mice (P<0.05) and was smaller in UUO3d mice compared with UUO5d mice obviously (P<0.05). Acute kidney injury could be observed in UUO3d+IR mice, such as massive inflammatory cells infiltration, tubules dilation, brush border disappearance, tubular epithelial cells vacuolar degeneration, necrosis, casting formation, coexisting with chronic lesions: thinner cortex, broadened interstitial space, and increased blue stained matrix. Acute kidney injury score in UUO3d+IR mice was higher than that in IR mice significantly (P<0.05), and serum creatinine level increased significantly in UUO3d+IR mice compared to Sham mice (P<0.05). Caspase-3 expression increased and ki67 positive tubular cells decreased in UUO3d+IR mice than those in IR mice obviously (P<0.05). Conclusion Earlier renal fibrosis aggravates acute kidney injury induced by ischemia reperfusion in mice through increasing apoptosis and decreasing proliferation of tubular epithelial cells.

Résumé

Objective@#To investigate the clinicopathologic features of cardiac myxofibrosarcomas.@*Methods@#The clinical data, pathomorphologic and immunohistochemical features were evaluated in five cases of cardiac myxofibrosarcoma collected from January 2009 to December 2014, with relevant literature review.@*Results@#Five patients with cardiac myxofibrosarcoma, including four women and one man [age range 39-61 years; mean (50.4±9.0) years] were included. All tumors were broadbased and located mainly in the left atrium, with one case extending through the atrial wall and pericardium to the left lower lung lobe. The morphological grade was low in one case, intermediate in one, and high in three. Using Fédération Nationale des Centres de Lutte Contre le Cancer (FNLCC) grading system, one case was grade 1 and four cases were grade 2. Immunohistochemical analysis revealed diffuse and strong expression for vimentin in all cases. Smooth muscle actin and muscle specific actin were variably expressed. Complete tumor excision was performed in one case, and tumor debulking was performed in the other four cases. Clinical follow-up was available in three cases. One patient with en bloc excision of the tumor mass survived 13 months and the other two with tumor debulking died one month after surgery.@*Conclusions@#The most common location for cardiac myxofibrosarcoma is the left atrium. Some myxofibrosarcoma may be histologically bland and misdiagnosed as myxoma due to histological similarities. Thus caution should be exercised in their microscopic differentiation. Precise imaging, multidisciplinary approach and adequate initial surgery may contribute to improving the clinical outcomes of myxofibrosarcoma.

Objective To investigate the incidence of recurrence and occurrence rate of recurrence of hand-foot-and-mouth disease (HFMD)in Jiangbei District of Ningbo City between 2012 and 2014,analyze the influencing fac-tors,and provide a scientific basis for the prevention and control of HFMD.Methods Data of HFMD in Jiangbei in 2012-2014 were collected from China Disease Surveillance Information System,immunization data were from Im-munization Programme Information System of Ningbo City,the recurrent infectious cases were selected and analyzed by descriptive epidemiological methods.Results The occurrence rate of recurrent HFMD in Jiangbei in 2012-2014 was 5.40% ,the median month of patients with single occurrence and recurrence of HFMD were 33.77(20.03, 47.83)and 38.26(22.05,54.75)months respectively,median month of patients with the initial occurrence were 23.93(15.87,36.87)months,median of time interval of recurrent HFMD was 10.27(5.23,16.06)months. The oc-currence rate of recurrence was the highest in 3- years old group(χ2= 37.51,P<0.001). Most were scattered chil-dren and children in child-care center. Female was a protective factor of recurrence of HFMD (OR,0.73[95% CI, 0.57-0.92]),while children in child-care center was a risk factor (OR,1 .46[95% CI,1 .16-1 .84]). The median attack rate of recurrence in HFMD group and control group in blocks within 7 days were 10.36(9.29,11.44)/100000 and 8.95(8.16,9.74)/100000 respectively,there was significant difference(Z= -2.68,P<0.001). In-oculation frequency between recurrent HFMD group and control group was not significantly different (Z= -1.38,P= 0.17).Conclusion The epidemic of recurrence of HFMD was serious in Jiangbei District of Ningbo City between 2012 and 2014,boys and children in child-care center should be paid attention,contacts with patients should be re-duced,and targeted prevention and control measures should be carried out.

Résumé

<p><b>BACKGROUND</b>Numerous studies have investigated the association between adiponectin concentrations and diabetic retinopathy (DR) caused by type 2 diabetic mellitus. However, the results remain conflicting. We performed a meta-analysis to explore the relationship between adiponectin concentrations and risk of DR caused by type 2 diabetic mellitus from published articles.</p><p><b>METHODS</b>A published literature search was performed through the PubMed, Cochrane Library, EMBASE, Science Citation Index Expanded database, Chinese CNKI, and Chinese Wan Fang databases for articles published in English and Chinese. Pooled standardized mean differences (SMDs) and 95% confidence intervals (95% CIs) were calculated using random or fixed effects model. Heterogeneity between studies was assessed using the Cochrane Q test and I(2) statistics.</p><p><b>RESULTS</b>Nineteen studies with a total of 1 545 cases and 1 502 controls were retrieved. The original meta-analysis found a significant difference in the adiponectin concentrations between the DR and non-DR (NDR) groups. After excluding the high heterogeneity studies, the second meta-analysis also demonstrated the significant association (SMD (95% CI) = -0.62 (-0.80 to -0.44), P = 0.0001). According to the available data, there was statistical significance in the adiponectin concentrations considering non-proliferative DR (NPDR) versus NDR, PDR versus NPDR in Chinese populations with high heterogeneity.</p><p><b>CONCLUSION</b>Adiponectin concentrations are correlated with DR; however, the relationship between adiponectin concentrations and DR needs more in-depth investigations with larger sample sizes.</p>

Résumé

<p><b>BACKGROUND</b>Vascular endothelial growth factor (VEGF) is a major mediator of angiogenesis, and plays a key role in the pathogenesis of diabetic retinopathy (DR). This study was designed to identify the possible role of VEGF gene polymorphisms in the development of DR in type 2 diabetic patients in Chinese and clarify the relationship between VEGF serum levels and the risk of DR.</p><p><b>METHODS</b>This cross-sectional study included 1 040 Chinese subjects with type 2 diabetes mellitus. There were 372 patients diagnosed with DR in the case group and 668 patients without DR in the control group. DNA from each patient was analyzed for VEGF polymorphisms of -2578A/C (rs699947), -1154G/A (rs1570360), -460C/T (rs833061), +405C/G (rs2010963), and +936C/T (rs3025039) using MassARRAY compact analyzer. The VEGF serum levels were quantified by enzyme-linked immunosorbent assay (ELISA).</p><p><b>RESULTS</b>No evidence of association was observed between -2578 A/C (rs699947), +405C/G (rs2010963), +936C/T (rs3025039), and DR risk under stringent Bonferroni's correction. However, VEGF serum levels were significantly higher in DR patients than those of control group. The genetic variation of VEGF polymorphisms influenced VEGF serum levels; subjects carrying the VEGF -2578 C/C (rs699947) genotype had greater VEGF serum levels than those carrying the C/A genotype and VEGF serum levels were significantly higher in CC genotype of the +405C/G (rs2010963) compared with those of the other genotypes.</p><p><b>CONCLUSIONS</b>The data did not suggest significant association between the VEGF polymorphisms and DR risk under stringent Bonferroni's correction. However, our study indicated that DR patients have higher VEGF levels than diabetic patients without retinopathy, and -2578A/C (rs699947) and +405C/G (rs2010963) may be important factors in determining serum VEGF levels.</p>
