Oral contraceptive pretreatment does not improve outcome in microdose gonadotrophin-releasing hormone agonist protocol among poor responder intracytoplasmic sperm injection patients

Purpose To compare oral contraceptive (OC) pretreatment plus microdose GnRH-a in flare-up protocol and non-OC microdose GnRH-a in flare-up protocol among poor responder ICSI patients. Methods A retrospective analysis of poor responder ICSI patients. Patients were divided into two groups according to used microdose protocol. Precycle treatment with OC followed by follicular phase administration of 40 μg sc leuprolide acetate (LA) every 12 h beginning on after 2 day pill-free period and rFSH administration was begun on the third day of LA administration (OC-Group, n = 26). Alternatively on day 2 after menses, patients were administered similar stimulation regime (non-OC Group, n = 27). Results There were no significant differences between groups in the number of oocytes, peak estradiol levels, endometrial thickness, fertilization rates and embryo quality. Implantations and pregnancy rates per embryo transfer were similar. Conclusion OC pretreatment plus microdose GnRHa in flare-up protocol does not offer advantages over non-OC microdose GnRHa in flare-up protocol among poor responder ICSI patients. Capsule Oral contraceptive pretreatment plus microdose GnRH-a in flare-up protocol does not offer advantages over non-OC microdose GnRH-a in flare-up protocol among poor responder ICSI patients.     

腹腔注射攻毒在蜱媒脑炎病毒感染BALB/c小鼠中的应用

目的 研究腹腔注射攻毒在蜱媒脑炎病毒（TBEV）感染BALB/c小鼠中的应用。方法 TBEV以103、104空斑形成单位（PFU）的攻毒剂量经腹腔注射感染BALB/c小鼠,观察小鼠的感染症状、体重变化与生存率。通过H-E染色显示小鼠脑、脾的病理改变,采用免疫组织化学检测小鼠脑、脾中TBEV蛋白的表达,空斑实验检测小鼠脑、脾中病毒滴度的动态变化。结果 TBEV感染第3天小鼠体重开始下降,第6天104 PFU组小鼠出现弓背、后肢瘫痪症状,第7天104 PFU组小鼠开始死亡,第9天103 PFU组小鼠全部死亡。与对照组小鼠相比,感染组小鼠的体重在第5~8天降低具有显著性差异（P<0.05或P<0.001）;小鼠生存率降低差异显著（P<0.01）。TBEV蛋白动态表达于感染组小鼠的脑与脾。103 PFU TBEV感染第7天,小鼠脑内TBEV滴度高达（1.3?0.6）×105 PFU/mL,而脾中滴度为（1.3?0.6）×103 PFU/mL。结论 经腹腔注射攻毒,TBEV在BALB/c小鼠体内建立感染,可增殖并具致病性。     

复方苦参注射液联合化疗对晚期胃癌患者生活质量的影响

目的：观察复方苦参注射液联合化疗对晚期胃癌患者生活质量影响。方法：回顾性分析70例晚期胃癌患者的治疗,治疗组化疗联合复方苦参注射液20ml＋生理盐水250ml,静脉滴注1次／d,连续2周,对照组单用化疗,每3周重复,共4个治疗周期,观察治疗前后疼痛、体重、食欲、karnofsky评分。结果：在控制疼痛、食欲改善方面,治疗组均优于对照组,差异有显著性（P〈O．05）;体重治疗前后比较差异无统计学意义（P〉0．05）。结论：复方苦参注射剂联合化疗能缓解疼痛,改善症状,提高患者生存质量。

目的：观察改良方法气管内滴入肺表面活性物质（pulmonary surfactant,PS）治疗新生儿肺透明膜病（Neonatal Hyaline Membrane Disease,HMD）的疗效。方法：选取96例新生儿肺透明膜病患儿,按随机数字表法分为治疗组（n=48）和对照组（n=48）,对照组采用传统的多体位间断非密闭式气管内滴入PS;治疗组应用经头皮针气管导管侧壁刺入持续气管内滴入PS,观察比较两组的各观察指标及临床转归情况。结果：治疗组的平均操作时间明显少于对照组,差异有统计学意义（P〈0.05）;且滴药过程中脱管率、管口溢药率、脉搏氧饱和度下降率及呼吸机相关性肺炎（VAP）发病率均明显低于对照组,差异均有统计学意义（P〈0.05）。结论：应用改良方法即经头皮针气管导管侧壁刺入持续气管内滴入PS成功率高,操作简单、快速,注药过程平缓,减少了脱管、药液喷出浪费、一过性缺氧及VAP的发生,是一种更快捷、方便、安全、经济、有效的给药方法,值得推广。     

Nanomaterials for Inner Ear Diseases: Challenges,Limitations and Opportunities

The inner ear is located deep in the temporal bone and has a complex anatomy. It is difficult to observe and obtain pathological tissues directly. Therefore, the diagnosis and treatment of inner ear diseases have always been a major clinical problem. The onset of inner ear disease can be accompanied by symptoms such as hearing loss, dizziness and tinnitus, which seriously affect people’s lives. Nanoparticles have the characteristics of small size, high bioavailability and strong plasticity. With the development of related research on nanoparticles in inner ear diseases, nanoparticles have gradually become a research hotspot in inner ear diseases. This review briefly summarizes the research progress, opportunities and challenges of the application of nanoparticles in inner ear diseases.

Analysis of Mechanical Properties Related to Fiber Length of Closed-Loop-Recycled Offcuts of a Thermoplastic Fiber Composites (Organo Sheets)

Increasing demand for energy-efficient means of transport has steadily intensified the trend towards lightweight components. Thermoplastic glass fiber composites (organo sheets) play a major role in the production of functional automotive components. Organo sheets are cut, shaped and functionalized by injection molding to produce hybrid components, such as those used in car door modules. The cutting process produces a considerable amount of production waste, which has thus far been thermally recycled. This study develops a closed mechanical recycling process and analyzes the different steps of the process. The offcuts were shredded using two shredding methods and implemented directly in the injection-molding process. Using tensile tests and impact bending tests, the material properties of the recycled materials were compared with the virgin material. In addition, fiber length degradation via the injection-molding process and the influence of the waterjet-cutting process on the mechanical properties are investigated. Recycled offcuts are both comparable to new material in terms of mechanical properties and usability, and are also economically and ecologically advantageous. Recycling polypropylene waste with glass fiber reinforcement in a closed loop is an effective way to reduce industrial waste in a sustainable and economical production process.
