Objective: To analyze the trend in disease burden of stroke in Linping District, Hangzhou City from 2014 to 2023, so as to provide the basis for prevention and control of stroke. Methods: Data on incidence and mortality of stroke in Linping District from 2014 to 2023 were collected through the Chronic Disease and Death Cause Monitoring System of Hangzhou Center for Disease Control and Prevention. The disease burden was evaluated by calculating years of life lost (YLL), years lived with disability (YLD) and disability-adjusted life years (DALY) with reference to the methodology of the Global Burden of Disease Study, and standardized using the data of the seventh national population census in 2020. The trend was analyzed using average annual percent change (AAPC). The disease burden of stroke attributed to risk factors was calculated. Results: The crude incidence of stroke was 298.13/105 and the crude mortality was 62.72/105 in Linping District from 2014 to 2023. The YYL, YLD and DALY caused by stroke were 49 413.60, 8 197.68, and 57 611.28 person-years, respectively, with decreasing trends in YLL and DALY, and an increasing trend in YLD (AAPC=-12.663%, -10.427% and 3.035%, all P<0.05). The standardized YLL rate, standardized YLD rate and standardized DALY rate were 9.54‰, 1.53‰ and 11.07‰, respectively, showing decreasing trends (AAPC=-16.011%,-0.975% and -13.791%, all P<0.05). Higher standardized DALY rate (P<0.05) and slower decline were seen in men than in women (AAPC=-13.025% vs. -14.550%, both P<0.05). The highest DALY of stroke was attributed to combined risk factors (men, 18 754.05 person-years; women, 13 256.60 person-years), followed by hypertension (men, 12 231.23 person-years; women, 9 373.77 person-years). The DALY of stroke attributed to smoking was 15.67 times higher in men than in women, and the DALY of stroke attributed to a lack of exercise was 1.27 times higher in women than in men. Conclusion There was an overall decreasing trend in the disease burden of stroke in Lingping District from 2014 to 2023, with a higher disease burden in men. The coexistence of multiple risk factors had a greater impact on stroke.

Objective:To observe the clinical effect of TOMY self-ligation appliance technique in the treatment of anterior crossbite and moderate crowding, and to explore its clinical application.Methods:A patient, manifested as anterior crossbite and moderate dentition crowing, diagnosed as Angle class Ⅲ subclass malocclusion, MaoⅡ1+Ⅰ1 malocclusion, high angle,and facial asymmetry, was selected.This patient was treated with TOMY self-ligation appliance technique without tooth extraction.The length and width of the dental arch, the width of the alveolar bone and the width of the basal arch were measured before and after treatment;the lateral radiographs of the patient were taken too.Results:After treatment,the upper and lower dentition arranged in neat rows, reached a neutral occlusal relationship;SNA, SNB and ANB had no obvious changes;the lip inclination of anterior teeth was increased by 10 degrees, and reached the normal value;the upper and lower dental arch width, alveolar bone width, basal bone arch width and dental arch length were lower than before treatment.Conclusion:For the patient with anterior crossbite and moderate dental crowding treated with non-extraction, the TOMY self-ligation technique can be considered to use, by increasing the arch width and length to improve the anterior crossbite and moderate crowding, in order to achieve the effective treatment.

Boys appeared sec-ondary sex characteristics around 10 years old;Cortisol and promote adrenal cortical hormone with 2 cases of obese children were in the normal range,but c-peptide and insulin were elevatory;The results of IGF-1 were in the normal range. ConclusionChemotherapy had no significant effect on growth development and endocrine function for patients with ALL.

Objective To investigate the clinical efficacy of intravitreal injection of Lucentis combined with pan retinal photocoagulation and trabeculectomy for neovascular glaucoma(NVG). Methods Seventeen eyes of 15 patients with NVG were treated by 0.5 mg Lucentis intravitreal injection first. Trabeculectomy was performed 7 days later and Pan retinal photocoagulation 2 weeks later. Iris,anterior chamber angle neovascularization,intraocu?lar pressure ,and visual acuity were observed in the following 6 months. Results Iris and anterior chamber angle neovascularization were completely regressed 7 days after the injection in 17 eyes. Six months after photocoagulation, 6 eyes had different degrees of improvement in visual acuity,10 eyes no change in visual acuity and 1 eye decreased from anterior index to immediate manual. There was significant difference in pre?treatment IOP and postoperative IOP( t = 12.75 ,10.26 ,9.73 ,10.77 ,P < 0.01 ). No serious complications were observed after intravitreal injec?tion and trabeculectomy. Conclusions Intravitreal injection of Lucentis could significantly accelerate the regres?sion of iris and anterior chamber angle neovascularization ,which could improve the successful rate of trabeculecto?my and pan retinal photocoagulation. Intravitreal injection of Lucentis combined with trabeculectomy and panretinal photocoagulation is safe and effective for NVG.

Based on the structure and motion bionic principle of the normal adult fingers, biological characteristics of human hands were analyzed, and a wearable exoskeleton hand function training device for the rehabilitation of stroke patients or patients with hand trauma was designed. This device includes the exoskeleton mechanical structure and the electromyography (EMG) control system. With adjustable mechanism, the device was capable to fit different finger lengths, and by capturing the EMG of the users' contralateral limb, the motion state of the exoskeleton hand was controlled. Then driven by the device, the user's fingers conducting adduction/abduction rehabilitation training was carried out. Finally, the mechanical properties and training effect of the exoskeleton hand were verified through mechanism simulation and the experiments on the experimental prototype of the wearable exoskeleton hand function training device.

We constructed plasmid pMTac to overexpress 3-ketosteroid-Δ1-dehydrogenase (KSDD) in Mycobacterium neoaurum JC-12 for improving androst-1,4-diene-3,17-dione (ADD) production. To construct pMTac, pACE promoter on pMF41 was replaced by tac promoter, and then four recombinants were constructed, which were M. neoaurum JC-12/pMF41-gfp, M. neoaurum JC-12/pMTac-gfp, M. neoaurum JC-12/pMF41-ksdd and M. neoaurum JC-12/pMTac-ksdd. Fluorescence detection results show that much more green fluorescent protein (GFP) was expressed in M. neoaurum JC-12/pMTac-ksdd than M. neoaurum JC-12/pMF41-ksdd. The activity of KSDD was 2.41 U/mg in M. neoaurum JC-12/pMTac-ksdd, 6.53-fold as that of M. neoaurum JC-12 and 4.36-fold as that of M. neoaurum JC-12/pMF41-ksdd. In shake flask fermentation, ADD production of M. neoaurum JC-12/pMTac-ksdd was 5.94 g/L, increased about 22.2% compared to the original strain M. neoaurum JC-12 and 12.7% to M. neoaurum JC-12/pMF41-ksdd. AD (4-androstene-3,17-dione) production of JC-12/pMTac-ksdd was 0.17 g/L, decreased 81.5% compared to M. neoaurum JC-12 and 71.2% to M neoaurum JC-12/pMF41-ksdd. In the 5 L fermenter, 20 g/L phytosterols was used as substrate, ADD production of M. neoaurum JC-12/pMTac-ksdd was improved to 10.28 g/L. pMTac is favorable for expressing KSDD in M. neoaurum JC-12, and overexpression of KSDD has beneficial effect on ADD producing, and it is the highest level ever reported using fermentation method in M. neoaurum.
