    Abstract: The impact of some prognostic factors on breast cancer survival has been shown to vary with time since diagnosis. However, this phenomenon has not been evaluated in Asians. In the present study, 4886 patients were recruited from the Shanghai Breast Cancer Survival Study, a longitudinal study of patients diagnosed during 2002–2006, with a median follow-up time of 11.2 years. Cox model incorporating time-by-covariate interactions was used to describe the time-varying effects of prognostic factors related to overall survival and disease-free survival. Age ≥65 years showed a progressively negative effect on breast cancer prognosis over time, whereas tumour size 〉 2 cm had a lasting and constant impact. Age significantly modified the effects of the tumour grade, nodal status and oestrogen receptor (ER) status on breast cancer survival. The detrimental effect of poorly differentiated tumours was time limited and more obvious in patients aged 45–54 years. Having ≥4 positive lymph nodes had a persistent and negative impact on prognosis, although it attenuated in later years; the phenomenon was more prominent in the 55–64-year age group. ER-positive status was protective in the first 3 years after diagnosis but was related to a higher risk of recurrence in later years; the time-point when ER-positive status turned into a risk factor was earlier in younger patients. These results suggest that older age, positive lymph node status, larger tumour size and ER-positive status are responsible for late death or recurrence in Asian breast cancer survivors. Extended endocrine therapy should be given earlier in younger ER-positive patients.

    Abstract: Mitochondrial dysfunction can lead to degeneration in the central nervous system. F1Fo-ATPase catalyzes most of the intracellular ATP synthesis which plays an essential role in cellular energy supply. The dimerized assembly of F1Fo-ATPase underlies the rotational catalytic function and regulates the mechanisms of oxidative phosphorylation. F1Fo-ATPase dysfunction is involved in a variety of neurological diseases, including epilepsy, Alzheimer's disease, and Parkinson’s disease. Dysregulated expression, activity, and localization of F1Fo-ATPase subunits and the interactions with pathogenic proteins result in decreased F1Fo-ATPase activity and ATP production, and aggravated oxidative stress.

    Abstract: In this paper, Ag 3 Sn nanoparticles were prepared by chemical method and added into SAC305 solder in different proportions to explore the effects of the Ag 3 Sn on the wettability, melting performance, metallographic structure, and mechanical property of the solder. The results show that a small amount of Ag 3 Sn nanoparticles were able to reduce the wetting time, increase the maximum wetting force, and expand the spreading area. The melting performance was also improved. Ag 3 Sn nanoparticles were also found to significantly refine the solder structure in the metallographical. The best comprehensive performance was achieved with the addition of 0.5% Ag 3 Sn nanoparticles. These Ag 3 Sn nanoparticles effectively improved the morphology of the IMC at the interface and effectively reduced the thickness of the IMC layer. The addition of nano Ag 3 Sn increased the diffusion activation energy and stabilized the interface. Moreover, the growth of the IMC layer was inhibited by 0.5% Ag 3 Sn, as indicated by aging results. The addition of Ag 3 Sn nanoparticles increases the tensile strength and Vickers hardness of the solder joint. When the amount of Ag 3 Sn nanoparticles was 0.5 wt%, the tensile strength reached the maximum of 17.45 MPa. The microhardness value of the solder is greatly increased, which reaches 311 HV. Finite element simulation showed that the service life of the solder was prolonged by adding the appropriate amount of Ag 3 Sn nanoparticles. The paper demonstrates a method of “nano” solder paste preparation. Results show that the addition of Ag 3 Sn nanoparticles plays an important role in the interfacial reaction and mechanical properties between the SAC solder and Cu substrate.

    Abstract: HfO 2 –Sm 3 TaO 7 ceramics are prepared through a solid-state reaction method. The X-ray diffraction and structural refinement show that the phase structures of HfO 2 –Sm 3 TaO 7 ceramics are an ordered orthorhombic phase and the space groups are belonging to Ccmm . The degree of the structural disorder increases with increasing HfO 2 content. The solid solution mechanism reveals that Hf 4+ exists in the form of interstitial ions that cause crystal expansion when the doping content is less than 4 mol%. When the doping concentration of HfO 2 ≥ 4 mol%, the Hf 4+ ions can substitute an equal number of Sm 3+ and Ta 5+ ions. The phase transition of Sm 3 TaO 7 ceramics is removed with increasing HfO 2 content, and the 8 mol% HfO 2 –Sm 3 TaO 7 ceramics have a high thermal expansion coefficient of 10.2 × 10 −6 K −1 at 1200 °C. The 2 mol% HfO 2 –Sm 3 TaO 7 ceramics have the lowest thermal conductivity (1.03 W/m K at 900 °C), which is lower than previous research of the 7–8 YSZ. The outstanding thermophysical properties of HfO 2 –Sm 3 TaO 7 ceramics indicate that they are potential thermal-barrier coating materials.

    Abstract: The estimated lifetime risk of stroke was the highest in East Asia worldwide, especially in China. Antihypertensive therapy can significantly reduce stroke mortality. However, blood pressure control is poor. Medication adherence is a barrier as patients’ out-of-pocket costs have risen. We aimed to take advantage of a free hypertension pharmacy intervention and quantified the impact on stroke mortality. Methods A free pharmaceutical intervention program was implemented in Deqing, Zhejiang province in April 2018. Another non-pharmaceutical intervention, social distancing due to the pandemic of Coronavirus disease 2019 (COVID-19), was also key to affecting stroke mortality. We retrospectively collected the routine surveillance data of stroke deaths from Huzhou Municipal Center for Disease Prevention and Control in 2013–2020 and obtained within-city mobility data from Baidu Migration in 2019–2020, then we quantified the effects of both pharmaceutical intervention and social distancing using Serfling regression model. Results Compared to the predicted number, the actual number of stroke deaths was significantly lower by 10% (95% CI, 6–15%; p   & lt; 0.001) from April 2018 to December 2020 in Deqing. Specifically, there was a reduction of 19% (95% CI, 10–28%; p   & lt; 0.001) in 2018. Moreover, we observed a 5% (95% CI, −4 – 14%; p  = 0.28) increase in stroke mortality due to the adverse effect of COVID-19 but it wasn’t statistically significant. Conclusion Free hypertension pharmacy program has great potential to prevent considerable stroke deaths. In the future, the free supply of low-cost, essential medications that target patients with hypertension at increased risk of stroke could be taken into account in formulating public health policies and guiding allocations of health care resources.

    Abstract: Objectives: We tended to explore the association of indoor air pollution (IAP) and non-neoplastic digestive system diseases (NNDSD) among the Chinese middle-aged and older population. Methods: From 2011 to 2018, we included 7884 NNDSD-free adults from the China Health and Retirement Longitudinal Study (CHARLS). Physician-diagnosed NNDSD was obtained by self-reported information at baseline and updated across follow-up surveys. We investigated the associations between baseline exposure of solid fuel use for cooking and/or heating and NNDSD diagnosed during follow-up through Cox proportional hazard models. Furthermore, we examined the relationship between cooking fuel switching and NNDSD diagnosed during follow-up. Results: Solid fuel use for cooking and/or heating was positively associated with NNDSD after adjusting for potential confounders. The risk of NNDSD among subjects who always use solid fuel for cooking (adjusted hazard ratio [aHR]: 1.42; 95% confidence interval [CI] : 1.09, 1.84) was higher than those with always clean fuels. Moreover, we found a lower NNDSD risk among participants who switched from solid to clean cooking fuel (aHR: 0.65; 95% CI: 0.49, 0.87) than those with always solid fuels. Conclusion: Our present study shows that indoor solid fuel use is a dependent risk factor for NNDSD. Moreover, switching to clean fuel may contribute to the prevention of digestive system illnesses.

    Abstract: Let G be a finite cyclic group of order n. The Erdős–Ginzburg–Ziv theorem states that each sequence of length 2n - 1 over G has a zero-sum subsequence of length n. A sequence without a zero-sum subsequence of length n is called n-zero-sum free. Savchev and Chen characterized all the n-zero-sum free sequences of length n + k - 1 over G, where [Formula: see text]. In the present paper, we determine all the n-zero-sum free sequences of length [Formula: see text] over G.
