排卵功能障碍是导致不孕症的首要因素,包括无排卵和黄体功能不全。促排卵是治疗排卵障碍性不孕的常用方法。西医治疗常采用克罗米芬、来曲唑、促性腺激素及促性腺激素释放激素类似物等进行综合治疗,经多年临床验证,诱导排卵疗效肯定,但在治疗时会引起药物不良反应,如多胎妊娠、卵巢过度刺激综合征、子宫内膜增生不良等临床问题。中医药治疗排卵障碍性不孕亦具有较好的疗效,与西医治疗相比,具有妊娠率高、并发症少等优势。文章总结周士源教授治疗运用中药调周法治疗排卵障碍性不孕的临证经验。周士源教授认为排卵障碍主要责之于肾中阴阳转化与消长失衡,引发月经不调,故而调理月经为治疗排卵障碍性不孕的关键,巧用中药周期疗法以助孕治疗,取得良好的临床效果。

A simple immune-based multi-objective optimizer(IBMO) is proposed, and a rigorous running time analysis of IBMO on three proposed bi-objective pseudo-Boolean functions(Bi-Trap, Bi-Plateau and Bi-Jump) is presented. The running time of a global simple evolutionary multi-objective optimizer(GSEMO) using standard bit mutation operator with IBMO using somatic contiguous hypermutation(CHM) operator is compared with these three functions. The results show that the immune-based hypermutation can significantly beat standard bit mutation on some well-known multi-objective pseudo-Boolean functions. The proofs allow us to understand the relationship between the characteristics of the problems and the features of the algorithms more deeply. These analysis results also give us a good inspiration to analyze and design a bio-inspired search heuristics.

Improvement of integrated battlefield situational awareness in complex environments involving dynamic factors such as restricted communications and electromagnetic interference(EMI)has become a contentious research *** certain mission environments,due to the impact of many interference sources on real-time communication or mission requirements such as the need to implement communication regulations,the mission stages are represented as a dynamic combination of several communication-available and communication-unavailable ***,the data interaction between unmanned aerial vehicles(UAVs)can only be performed in specific communication-available *** cooperative search algorithms cannot handle such situations *** solve this problem,this study constructed a distributed model predictive control(DMPC)architecture for a collaborative control of UAVs and used the Voronoi diagram generation method to re-plan the search areas of all UAVs in real time to avoid repetition of search areas and UAV collisions while improving the search efficiency and safety *** attention mechanism ant-colony optimization(AACO)algorithm is proposed for UAV search-control decision *** search strategy is adaptively updated by introducing an attention mechanism for regular instruction information,a priori information,and emergent information of the mission to satisfy different search expectations to the maximum *** results show that the proposed algorithm achieves better search performance than traditional algorithms in restricted communication constraint scenarios.

The balanced development of the elementary education sector has been a long goal pursued by the education departments of various places, and is also an outcome expected by the people. Based on a study of the equilibrium of the spatial distribution of the capacity saturation models of all the primary schools in Changsha’s (China) five core districts, the results show that the overall geographical distribution of the primary schools in Changsha is relatively balanced, based on the natural characteristics of Changsha, such as human geography, and the moderate gradient between the central urban area and the primary schools in the suburbs and outer suburbs. Then the Theil index model was introduced, and the results of the model analysis show that the differences between elementary schools in Changsha urban area are relatively small, and the main differences originate from between districts rather than within districts, and subtle differences among regions mainly reflect in the teacher strength.

目的探讨塞替哌、氟达拉滨联合白消安(TBF)的预处理方案用于单倍体造血干细胞移植的安全性及有效性。方法回顾性分析苏州大学附属第一医院和苏州弘慈血液病医院2020年至2023年期间行单倍体造血干细胞移植的574例受者资料,其中20例接受TBF预处理方案(TBF组),其余554例接受白消安+环磷酰胺(mBUCY)预处理方案,采用倾向性匹配方法,匹配比例为1:2,以疾病类型、受者年龄及受者性别作为匹配因素,最终筛选出40例mBUCY预处理方案的受者作为对照(mBUCY组)。根据Bearman评分标准评估TBF预处理相关毒性;与mBUCY组比较,观察TBF方案在预处理相关毒性,长期生存的安全性及有效性。结果TBF组20例受者预处理期间主要的并发症为I~Ⅱ级口腔黏膜炎和胃肠道症状,未发生严重的心血管不良事件。TBF组粒细胞系重建时间为11 d(9~14)d,mBUCY组时间为12 d(10~28)d,两组比较差异无统计学意义(P=0.2)。TBF组巨核细胞系重建时间为18 d(9~100)d,mBUCY组时间为20 d(11~100)d,两组比较差异无统计学意义(P=0.7)。TBF组100 dⅡ~Ⅳ度急性移植物抗宿主病(acute graft versus host disease,aGVHD)的发病率低于mBUCY组(5%比35%,P=0.01)。TBF组和mBUCY组受者的1年总存活率分别为68%和62%,差异无统计学意义(P=0.98),TBF组1年无复发无GVHD存活(graft-versus-host disease-free,relapse-free survival,GRFS)率优于mBUCY组,但差异无统计学意义(63%比37%,P=0.06)。结论TBF预处理方案在单倍体造血干细胞移植中应用毒性低,安全性较好。TBF预处理方案与mBUCY预处理相比,能减少移植后Ⅱ~Ⅳ度aGVHD发生,可能改善受者的GRFS。

The energy harvesting technology for the ubiquitous natural wind enables a desirable solution to the issue of distributed sensors in the bridge environmental sensing Internet of Things(Io T)system being restricted to conventional energy *** this work,a self-powered system based on a compact galloping piezoelectric-triboelectric energy harvester(GPTEH)is developed to achieve efficient wind energy *** GPTEH is constructed on the prototype of a cantilever structure with piezoelectric macro-fiber composite(MFC)sheets and a rectangular bluff body with triboelectric nanogenerators(TENGs).Through a special swing-type structural design with iron blocks inside the bluff body,the GPTEH exhibits preferable aerodynamic behavior and excellent energy conversion efficiency,compared to conventional cantilever kind of piezoelectric wind energy harvester(PWEH).The GPTEH also demonstrates the capability of high output power density(PEH of 23.65 W m^(-2)and TENG of 1.59 W m^(-2)),superior response wind speed(about 0.5 m s^(-1)),and excellent long-term stability(over 14000 cyclic tests).Furthermore,a power management system is developed to efficiently utilize the output energy from GPTEH to power the sensors and wirelessly transmit environmental data to the *** proposed GPTEH-powered system exhibits a great potential for the bridge environmental monitoring and Io T technologies.
