Objective: To investigate the incidence trend of diabetes among children and adolescents in Ningbo City, Zhejiang Province from 2011 to 2021, so as to provide the basis for the prevention and control of diabetes among children and adolescents. Methods: Data on diabetes incidence among children and adolescents aged 0 to 18 years in Ningbo City were collected through the Diabetes Monitoring Platform of the Ningbo Chronic Disease Collaborative Management System from 2011 to 2021. Crude incidence rates were calculated and standardized using data from the Sixth National Population Census in 2010. The trend of incidence rates were analyzed by average annual percent change (AAPC). Results: A total of 701 cases of diabetes among children and adolescents were reported in Ningbo City from 2011 to 2021. The crude and standardized incidence rates were 6.86/105 and 7.27/105, respectively, showing upward trends (AAPC=5.886%, 7.147%, both P<0.05). The crude and standardized incidence rates of type 1 diabetes mellitus were 3.36/105 and 3.35/105, respectively, with no significant trend observed (AAPC=1.229%, 1.449%, both P>0.05). The crude incidence rate was higher in children and adolescents aged 10 to <15 years (4.56/105) than in other age groups (all P<0.05). The standardized incidence rate was higher in females than in males (3.49/105 vs. 3.04/105, P<0.05). The standardized incidence rate was higher in urban areas than in rural areas (3.60/105 vs. 3.15/105, P<0.05). The crude and standardized incidence rates of type 2 diabetes mellitus were 3.43/105 and 3.87/105, respectively, showing upward trends (AAPC=4.904%, 7.579%, both P<0.05). The crude incidence rate was higher in children and adolescents aged 15 to 18 years (10.53/105) than in other groups (all P<0.05). The crude incidence rates in children and adolescents who aged 10 to <15 years and 15 to 18 years showed upward trends (AAPC=15.030%, 6.637%, both P<0.05). The standardized incidence rate was higher in males than in females (4.01/105 vs. 3.57/105, P<0.05). The standardized incidence rate was higher in urban areas than in rural areas (4.57/105 vs. 3.34/105, P<0.05). Conclusions From 2011 to 2021, the incidence of type 2 diabetes mellitus showed an upward trend, with cases mainly concentrated in children and adolescents aged 15 to 18 years, males, and those living in urban areas. The incidence of type 1 diabetes mellitus remained stable, with cases mainly concentrated in children and adolescents aged 10 to <15 years, females, and those living in urban areas.

Objective To study the mutations of Env sequence of SIVmac239 after infection of Chinese rhesus monkeys, and compare the differences and characteristics of Gp120 sequences of enterotropic and neurotropic SIV strains. Methods Six strains of simian immunodeficiency virus were analyzed in this study: four separated from peripheral blood mononuclear cells of SIVmac239-infected monkeys and two neurotropic SIVmac251 strains.Isolated and cultured monoclonal virus was obtained by limiting dilution assay.Gp120 sequences were amplified after the RNA extraction and phylogenetic analysis was processed thereafter.So did the Gp120 amino acid sequence and N-glycosylation sites analysis of the enterotropic and neurotropic strains.Results SIVmac239 had different mutations in four rhesus monkeys.The diversity in amino acid sequences of the enterotropic and neurotropic strains concentrated in the V1 and V4 regions of Gp120.The enterotropic strains had an addition of glycosylation site in V4 but the glycosylation site changes of neurotropic strains were located in the conservative regions of C1, C2 and C3.Conclusions The addition of one glycosylation site in V4 region of GP120 and loss of one glycosylation site in C1 region are associated with enhanced enterotropism and neurotropism.The differences between the enterotropic and neurotropic strains are not dipicted in Gp120 V3 region which is closely related with the tropism of strains.

Objectives To investigate the neuroprotective mechanism of vagus nerve stimulation ( VNS) by stimulating the vagus nerve in ischemic cerebral tissue in a rat model of transient focal cerebral ischemia. Methods Twenty-six adult male Sprague-Dawley ( SD ) rats were randomly divided into sham operation group (n=6),model group (n=10),and VNS-treated group (n=10) . The model of rat transient focal cerebral ischemia was induced by the intraluminal suture method. At 30 min after modeling,the right side neck VNS in the VNS-treated group was stimulated ( stimulus intensity 0. 5 mA, interval 0. 5 ms, frequency 20 Hz),once every 5 min within 1 h,and once for 30 s. The model group repeated the steps of the VNS-treated group,but did not stimulate. The sham operation group repeated the experimental steps,but it neither embolized the vessels nor stimulated nerves. The changes of cerebral blood flow were monitored with a laser Doppler flowmeter. The rats were sacrificed after 24 h. The expressions of interleukin 6(IL-6) and caspase-3 in brain tissue were determined by immunohistochemistry staining. The neuronal apoptosis was observed by the in situ end-labelling technique. Results ( 1 ) Compared with the sham operation group, the number of positive cells of IL-6,caspase-3,and the numbers of neuronal apoptosis in the model group were significantly increased (20. 7 ± 5. 0 cells/HP vs. 2. 3 ± 1. 0 cells/HP,44. 5 ± 9. 5 cells/HP vs. 0,30. 9 ± 9. 0 cells/HP vs.0).Thereweresignificantdifferences(P<0.05).(2)Comparedwiththemodelgroup,thenumber of positive cells of IL-6(10. 9 ± 3. 7 cells/HP),the caspase-3 (18. 9 ± 6. 7 cells/HP),and the numbers of neuronal apoptosis (14. 0 ± 5. 2 cells/HP) in the VNS-treated group decreased significantly. There were significant differences (P<0. 01). (3) Before and after modeling,there were no significant differences in cerebral blood flow in various periods between the model group and the VNS-treated group (P>0. 05). Conclusion The neuroprotective mechanism of VNS for cerebral ischemia may be associated with the inhibition of neuronal apoptosis and decreasing inflammatory response. It may not be associated with the changes of cortical cerebral blood flow.

To develop a LC-MS/MS method for the determination of five kinds of trace ginkgolic acids in diterpene ginkgolides meglumine injection materials, the column was Agilent ZORBAX Eclipse plus C18 (3.0 mm x 50 mm, 1.8 µm), and the mobile phase consisted of methanol-water (containing 0.2% formic acid) (95:5) at a flow rate of 0.5 mL · min(-1). The multiple reaction ion monitoring (MRM) with an ESI interface in the negative ion mode was selected. The results showed that the linear ranges of five kinds of ginkgolic acids were in the range of 0.2-36.0 µg · L(-1) (r ≥ 0.999 5). The lowest limit of quantification (LOQ) of ginkgo acid C13: 0, C15:1, C17:2, C15:0 and C17:1 were 0.18, 0.18, 0.21, 0.10 and 0.20 µg · L(-1), respectively. The average recovery was between 73.28% and 87.56%, and the average content of total ginkgolic acids in three batches of samples was in the range of 0.023-0.028 µg · g(-1), which was much lower than 2 µg · g(-1) prescribed in drug registration standards. This method is simple and rapid with high sensitivity, which can be used for the determination of five kinds of trace ginkgolic acids in diterpene ginkgolides meglumine injection materials.
