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 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.

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.

The aim of this study was to investigate the effect of Paris saponin I (PS I) on human gastric carcinoma cell growth and apoptosis and to explore the potential mechanisms. The proliferation of SGC7901 cells was monitored by the MTT cell viability assay, while the nuclear morphology of apoptotic cells was assessed by Hoechst 33258 staining. Flow cytometry was performed to analyze the cell cycle progression of propidium iodide (PI)-stained SGC7901 cells and the apoptotic rate of annexin V/PI-stained cells. Western blotting was used to examine the expression of several cell cycle proteins, including cyclin B1 and Cdk1, and the apoptosis-regulated proteins Bcl-2, Bax, cytochrome c, procaspase-9, and procaspase-3. The MTT assay demonstrated that PS I could induce significant dose- and time-dependent inhibition of SGC7901 cell proliferation. Marked morphological changes, including condensation of chromatin, nuclear fragmentation and apoptotic bodies were clearly shown on Hoechst 33258 staining. PSI treatment also resulted in the disruption of the cell cycle at G(2)/M and the induction of apoptosis. Following PSI treatment, the cell cycle-related proteins cyclin B1 and Cdk1 were down-regulated. Expression of the pro-apoptotic protein Bax was increased, while anti-apoptotic protein Bcl-2 decreased. PSI treatment resulted in elevated cytoplasmic cytochrome c and activation of the apoptotic proteases caspase-9 and caspase-3. These data indicate that PS acts as an inhibitor of proli I feration in SGC7901 cells by inducing cell cycle arrest and mitochondria-dependent apoptosis. PSI is a potential therapeutic agent against human gastric carcinoma.

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.

Objective To evaluate the potential use of a probe melting analysis (PMA) assay in detecting the embB mutations which confer resistance against ethambutol in Mycobacterium tuberculosis. Methods The analysis sensitivity and specificity of PMA were investigated by detecting a serially diluted H37 Rv DNA and a reference panel from National Institute for the Control of Pharmaceutical and Biological Product. Six hundred and thirteen sputum samples were collected from the Xiamen Center for Disease Control and Prevention, Xiamen First Hospital and Center for Zhangzhou Disease Control and Prevention from September 2009 to April 2010. The PMA assay was then evaluated by detecting 613 clinical isolates and the results were compared with the sequencing results. Results The PMA assay could specifically detect Mycobacterium tuberculosis and had a limit of detection of 3 copies per reaction. The assay results with 613 clinical isolates showed that PMA gave a 100% concordance with sequencing in the 583 qualified samples, among which 34 were mutations at embB 306,23 at embB 378-380, 3 at embB 406 and 3 at embB 497. Conclusions PMA assay is a sensitive and specific method enabling efficient detection of common embB mutations causing ethambutol-resistance. The rapidness of this method together with its reliability would facilitate its use in routine testing.
