目的：评价电针联合其他药物在甲状腺全切除术中提供镇痛和稳定血流动力学参数的有效性和安全性。方法：该随机对照试验囊括了100例患者，这些患者于2022年10月至2023年10月在越南国立针灸医院接受了甲状腺全切除术。患者被随机分为了两组。电针镇痛组（EA）对合谷穴（LI 4）、内关穴（PC 6）、水突穴（ST 10）、缺盆穴（ST 12）、翳风穴（SJ 17）5个穴位进行了电针刺激，对照组患者进行了双侧浅表颈丛神经阻滞。主要结局包括两组患者的镇痛水平和围手术期生命体征。此外，测定了EA组患者电针前后的疼痛阈值和血清β-内啡肽水平。结果：EA组和对照组分别有86%和76%的患者达到完全镇痛（A级），两组间无显著差异（P=1.00）。EA组患者接受EA后平均疼痛阈值翻倍（648.7(77.4) g/s vs. 305.3 (45.3) g/s, P <0.001），平均血清β-内啡肽水平增加了约13.5pg/m L(P <0.001)。所有患者在整个手术过程中的血流动力学维持稳定。结论：EA联合其他药物刺激了5个穴位，LI 4、PC 6、ST 10、ST 12和SJ 17，在甲状腺全切除术中耐受良好，有效地维持了适当的镇痛水平和血流动力学稳定性。

Investigating natural-inspired applications is a perennially appealing subject for scientists. The current increase in the speed of natural-origin structure growth may be linked to their superior mechanical properties and environmental resilience. Biological composite structures with helicoidal schemes and designs have remarkable capacities to absorb impact energy and withstand damage. However, there is a dearth of extensive study on the influence of fiber redirection and reorientation inside the matrix of a helicoid structure on its mechanical performance and reactivity. The present study aimed to explore the static and transient responses of a bio-inspired helicoid laminated composite(B-iHLC) shell under the influence of an explosive load using an isomorphic method. The structural integrity of the shell is maintained by a viscoelastic basis known as the Pasternak foundation, which encompasses two coefficients of stiffness and one coefficient of damping. The equilibrium equations governing shell dynamics are obtained by using Hamilton's principle and including the modified first-order shear theory,therefore obviating the need to employ a shear correction factor. The paper's model and approach are validated by doing numerical comparisons with respected publications. The findings of this study may be used in the construction of military and civilian infrastructure in situations when the structure is subjected to severe stresses that might potentially result in catastrophic collapse. The findings of this paper serve as the foundation for several other issues, including geometric optimization and the dynamic response of similar mechanical structures.

Background In Viet Nam, tuberculosis (TB) represents a devastating life-event with an exorbitant price tag, partly due to lost income from daily directly observed therapy in public sector care. Thus, persons with TB may seek care in the private sector for its flexibility, convenience, and privacy. Our study aimed to measure income changes, costs and catastrophic cost incurrence among TB-affected households in the public and private *** Between October 2020 and March 2022, we conducted 110 longitudinal patient cost interviews, among 50 patients privately treated for TB and 60 TB patients treated by the National TB Program (NTP) in Ha Noi, Hai Phong and Ho Chi Minh City, Viet Nam. Using a local adaptation of the WHO TB patient cost survey tool, participants were interviewed during the intensive phase, continuation phase and post-treatment. We compared income levels, direct and indirect treatment costs, catastrophic costs using Wilcoxon rank-sum and chi-squared tests and associated risk factors between the two cohorts using multivariate *** The pre-treatment median monthly household income was significantly higher in the private sector versus NTP cohort (USD 868 vs USD 578;P=0.010). However, private sector treatment was also significantly costlier (USD 2075 vs USD 1313;P=0.005), driven by direct medical costs which were 4.6 times higher than costs reported by NTP participants (USD 754 vs USD 164;P<0.001). This resulted in no significant difference in catastrophic costs between the two cohorts (Private: 55% vs NTP: 52%;P=0.675). Factors associated with catastrophic cost included being a single-person household [adjusted odds ratio [(aOR=13.71; 95% confidence interval (CI): 1.36–138.14;P=0.026], unemployment during treatment (aOR=10.86; 95%CI: 2.64–44.60;P<0.001) and experiencing TB-related stigma (aOR=37.90; 95%CI: 1.72–831.73;P=0.021).Conclusions Persons with TB in Viet Nam face similarly high risk of catastrophic costs whether treated in the
