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.

Inducing the degradation of KRAS represents a novel strategy to combat cancers with KRAS mutation. In this study, we identify ubiquitin-specific protease 2 (USP2) as a novel deubiquitinating enzyme of KRAS in multiple myeloma (MM). Specifically, we demonstrate that gambogic acid (GA) forms a covalent bond with the cysteine 284 residue of USP2 through an allosteric pocket, inhibiting its deubiquitinating activity. Inactivation or knockdown of USP2 leads to the degradation of KRAS, resulting in the suppression of MM cell proliferation in vitro and in vivo. Conversely, overexpressing USP2 stabilizes KRAS and partially abrogates GA-induced apoptosis in MM cells. Furthermore, elevated USP2 levels may be associated with poorer prognoses in MM patients. These findings highlight the potential of the USP2/KRAS axis as a therapeutic target in MM, suggesting that strategically inducing KRAS degradation via USP2 inhibition could be a promising approach for treating cancers with KRAS mutations.

OBJECTIVE To observe prenatal nicotine exposure (PNE) induced high sensitivity of hypo?thalamic-pituitary-adrenal (HPA) axis in offspring rats which were fed with a high-fat diet, and to explore the mechanism. METHODS Nicotine (2 mg·kg-1 per day) was injected subcutaneously to preg?nant Wistar rats from gestational day (GD) 9 to GD20,and then the young rats were naturally delivered. After weaning, half of the offspring was fed with a high-fat diet until postnatal weeks (PW) 20. The others were exposed to unpredictable chronic stress (UCS) from PW17 to PW20. The pathological changes in the hippocampus were analyzed by HE staining. The blood concentration of adrenocorticotropic hormone (ACTH) and corticosterone (CORT) was detected by RIA kits and ELISA kits, respectively. Meanwhile, real-time PCR was used to detect the mRNA expression of ACTH releasing hormone (CRH), arginine vasopressin (AVP), vesicular glutamate transporter 2 (VGluT2), glutamic acid decarboxylase 65 (GAD65), mineralocorticoid receptor (MR),glucocorticoid receptor (GR) and glutamic acid decarboxylase 67 (GAD67). RESULTS In the normal control group,UCS treatment increased the level of serum ACTH and CORT 1.96 and 3.24 times in female rats,but 1.63 and 3.54 times in male rats. In the PNE group, UCS treatment increased the level of serum ACTH and CORT 3.96 and 5.98 times in female rats, but 3.04 and 5.22 times male rats. PNE increased the mRNA expression of AVP in the female and male rats 2.04 and 1.13 times in UCS treatment control group, and the mRNA expression of hypothalamus CRH and the ratio of VGLuT2/ GAD65 were increased 2.49 and 1.14 times in female rats, respectively. Furthermore, the nicotine group exhibited histological changes to different degrees in the hippocampus and dentate gyrus area of the hippocampus. In the female and male nicotine groups, the mRNA ratio of hippocampal MR/GR decreased by 88.0% and 86.0% in comparison with the normal control group without UCS, and the mRNA expression of GAD67 was enhanced 1.38 and 1.97 times in female and male rats without UCS. In the female UCS treatment nicotine groups, the mRNA expression of GAD67 was increased 2.17 times compared with the UCS treatment control group. CONCLUSION PNE can induce a high sensibility of HPA axis in offspring rats fed with a high-fat diet. The imbalance of hippo?campus MR/GR and the enhanced expression of GAD67 mRNA may be involved.

A novel flow-injection chemiluminescence (FI-CL) method free of CL reagent was developed for the determination of captopril based on its enhancing effect on the CL derived from diperiodatoargentate(III)-sulfuric acid system. Compared with the conventional CL system, the CL system based on trivalent silver was characterized of good selectivity for the absence of CL reagent. The CL mechanism was discussed through CL spectra and UV–vis absorption spectra. The conditions of the FI-CL system were investigated and optimized. Under the optimal conditions, the relative CL intensity was linear with the captopril concentration in the range of 0.3–15.0 μg/mL. The detection limit for captopril was 0.05 μg/mL, and the relative standard deviation (n=11) was 2.0% for 5.0 μg/mL captopril. The proposed method was applied to the analysis of captopril in tablet and human urine with the recoveries of 83.1%–112.5%, and the relative standard deviations of 0.5%–4.4%. The results obtained by the proposed method agreed well with those obtained from HPLC method. The proposed method is fast, convenient, and cost-effective for the determination of captopril in medicine and biological samples.

Objective:To observe the effects of different moxibustion times on proteins of transient receptor potential vanilloid 3 (TRPV3) ion channel protein and synovial cell apoptosis in rats with rheumatoid arthritis (RA), to provide a new basis for the anti-inflammatory mechanism of moxibustion. Methods:A total of 50 Sprague-Dawley (SD) rats were divided into a normal group, a model group, moxibustion groupⅠ, moxibustion groupⅡ and moxibustion groupⅢ by complete randomization, with 10 rats in each group. Rats in the normal group were bred routinely, and rats in the model group were also bred routinely after successful modeling. After successful modeling, rats in moxibustion groupⅠ,Ⅱ andⅢ accepted consecutive moxibustion at Zusanli (ST 36) and Shenshu (BL 23) for 15 d, once a day, respectively 5 min, 20 min and 30 min for each session. The degree of paw edema was observed and recorded. Immunohistochemical assay was used to detect the protein expression of TRPV3 ion channel in dorsal root ganglia and spinal cord dorsal horn. Terminal-deoxynucleoitidyl transferase-mediated nick end labeling (TUNEL) was used to detect apoptotic synovial cell number. Results: At the end of treatment, paw circumference of rats in moxibustion groupⅡ andⅢ were significantly reduced as compared with that in the model group (P<0.05). TRPV3 ion channel protein expression of dorsal root ganglia and spinal cord dorsal horn was higher in the model group than that in the normal group (P<0.05); the TRPV3 ion channel protein expressions of dorsal root ganglia and spinal cord dorsal horn in moxibustion groupⅡ andⅢ were higher than that in moxibustion groupⅠ (P<0.05); apoptotic synovial cell number in the model group was larger than that in the normal group (P<0.05), and apoptotic synovial cell numbers in moxibustion groupⅡ andⅢ were significantly higher than that in the model group (P<0.05). Conclusion:Moxibustion of appropriate time could induce TRPV3 expression, and promote synovial cell apoptosis.

Clinical skills training center of Dongyang People's hospital introduced lean man-agement conception into the resident clinical skills training. The recruited residents were grouped by degree, the training contents were detailed, and teaching plans were normalized, and small class teach-ing and real-time feedback were implemented, which improved the normalization and standardization of resident training. The implementation of lean management leads to great progress in resident train-ing, but still needs further efforts. Only in the long-term management of standardization, can lean man-agement conception be embedded in daily work, making clinical skills training center play its role in cultivating medical talents effectively.
