OBJECTIVE: To systematically assess the effects of individualized Chinese medicines on recurrent urinary tract infections(rUTIs).METHODS: This study recruited 230 adult female patients in the remission phase of rUTIs from five hospitals in China. The patients were randomly allocated to two groups: an individualized Chinese medicine group(n = 114) and a control group(n = 116). Patients in the Chinese medicine group received individualized Chinese herbs, which were evaluated for syndrome *** in the control group received antibiotic treatment combined with a Chinese medicine placebo. The duration of treatment was three courses of four weeks each, with a three-month subsequent follow-up. UTI recurrence rate,Traditional Chinese Medicine(TCM) syndrome scores,36-item Short Form Survey(SF-36) score, and urine secretory immunoglobulin A(SIgA) were measured and analyzed before and after treatment in each group. RESULTS: Patients from the Chinese medicine group exhibited significant decreases in both short-and longterm UTI recurrence rates compared with the control group(P < 0.05). The changes in TCM syndrome scores between the Chinese medicine and control groups were significant(P < 0.05). The changes in the average SF-36 quality-of-life scores in the Chinese medicine group were also significantly higher than those in the control group after treatment(P < 0.05). The Chinese medicine group also demonstrated a significant increase in urine SIg A expression. CONCLUSION: Taken together, compared to the oftenused long-term antimicrobial prophylaxis during the remission stage of r UTIs, treating patients with an individualized Chinese medicine decoction by syndrome differentiation could effectively reduce the recurrence rate, improve the patients' TCM syndrome scores and quality of life, and enhance immunity, which in turn helps to prevent antibiotic resistance.

Radial well filled with phase change material has been proposed as a novel sand control method for hydrate exploitation. In order to reveal the sand control mechanism, CFD-DEM coupling method is applied to simulate the migration, settlement, and blockage processes of sand particles in the radial *** obtained results indicate that three scenarios have been recognized for sand particles passing through sand control medium, based on the diameter ratio of sand control medium to sand particle（Dd）:fully passing（Dd= 8.75-22.5）, partially passing and partially blocked（Dd= 3.18-5.63）, and completely blocked（Dd= 2.18-3.21）. After being captured by the sand control medium, sand particles can block pores, which increases fluid flow resistance and causes a certain pressure difference in the radial *** pressure in the radial well should be lower than the hydrate phase equilibrium pressure during sand control design, for the purpose of promoting hydrate decomposition, and sand capture. The length of the radial well should be optimized based on the reservoir pore pressure, production pressure difference,bottom hole pressure, and the pressure gradient in the radial well. It should be noticed that the sand control medium leads to a decrease in permeability after sand particles captured. Even the permeability is reduced to several hundred millidarcy, it is still sufficient to ensure the effective flow of gas and water after hydrate decomposition. Increasing fluid velocity reduces the blocking capacity of the sand control medium, mainly because of deterioration in bridging between sand particles.

Securing a comfortable, wearable compact frequency beam scanning antenna(FBSA) with robustness to deformation, low specific absorption rate(SAR), and good coverage of the surrounding environment for Internet of Things(IoT) applications, such as on-body navigation and wireless communication is an emerging challenge. In this work, a robust textile-based spoof plasmonic frequency scanning antenna utilizing higher-order modes is presented, which is also robust to deformation caused by the activities of the human body. The innovative design of the element ensures the high-efficiency transmission of the fundamental mode of spoof surface plasmon polaritons(SSPP) structure, providing the potential of being a multifunctional composite device in the compact on-body network. Besides, an artificial magnetic conductor(AMC) is designed underneath the SSPP structure, obtaining a low SAR value(0.113 W/kg), which ensures the safety of users. As a practical realization of this concept, a textile-based spoof plasmonic antenna was fabricated in the microwave regime and the performed experimental results show the proposed antenna has a single-beam radiation characteristic with a 70° beam scanning angle range when the frequency is 4.7–6.0 GHz with a high average realized gain of 13.15 dBi. And it still maintains a steady performance when faced with structure deformation, which proves its robustness. Wireless communication quality experiments are performed to demonstrate the proposed antenna can measure the angles of targets and realize wireless signal transmission to specific targets as the frequency varies, it may find great potential in the field of on-body IoT applications.
