Human gut microbiota play an essential role in both healthy and diseased states of humans. In the past decade, the interactions between microorganisms and tumors have attracted much attention in the efforts to understand various features of the complex microbial communities, as well as the possible mechanisms through which the microbiota are involved in cancer prevention, carcinogenesis, and anti-cancer therapy. A large number of studies have indicated that microbial dysbiosis contributes to cancer susceptibility via multiple pathways. Further studies have suggested that the microbiota and their associated metabolites are not only closely related to carcinogenesis by inducing inflammation and immune dysregulation, which lead to genetic instability, but also inter- fere with the pharmacodynamics of anticancer agents. In this article, we mainly reviewed the influ- ence of gut microbiota on cancers in the gastrointestinal （GI） tract （including esophageal, gastric, colorectal, liver, and pancreatic cancers） and the regulation of microbiota by diet, prebiotics, pro- biotics, synbiotics, antibiotics, or the Traditional Chinese Medicine. We also proposed some new strategies in the prevention and treatment of GI cancers that could be explored in the future. We hope that this review could provide a comprehensive overview of the studies on the interactions between the gut microbiota and GI cancers, which are likely to yield translational opportunities to reduce cancer morbidity and mortality by improving prevention, diagnosis, and treatment.

Anisotropic structures, nanoneedles, and nanospindles of rare earth hydroxychloride （RE（OH）2Cl） and oxychloride （REOCl）（rare earth=Eu and Tb） were synthesized. The rare earth hydroxychloride nanostructures were formed via a thermally assisted hydrolysis of the rare-earth sesquioxide nanocrystals. The morphological evolution of the nanostructures was studied using high-resolution transmission electron microscopy and scanning electron microscopy, while the structural evolution was investigated using X-ray diffraction techniques. The thermal stability of the rare earth hydroxychlorides was investigated using thermogravimetric analysis. The rare earth oxychloride nanospindles were synthesized via a simple heat-treatment of rare earth hydroxychloride nanospindles.

缺乏经验的操作者在紧急气管插管时可能造成食管穿孔。然而,食管损伤是发生在经多次检查的情况下的。食管穿孔一旦发生,可引起皮下气肿、气胸、紫绀、咽喉痛、发烧、纵隔炎、脓胸、心脏周围炎甚至死亡。及时诊断与手术治疗能有效地防止这些晚期并发症。作者报道1例发生于麻醉诱导和气管插管期间的食管穿孔,表现为即刻危急生命的呼吸困难——皮下气肿和双侧气胸,由于诊断治疗及时,病人痊愈。患者女性,62岁,因小肠梗阻入院,既往无明显异常。最初由于病人拒绝手术治疗而采用鼻胃管吸引,入院第(?)天,经左锁骨下静脉穿刺导管给予非肠道营养治疗。入院后第10天,病人同意腹部探查,术前,病人

Objective: The purpose of this prospective study was to determine whether the timing of prophylactic antibiotics at cesarean delivery influences maternal/neonatal infectious morbidity. Study design: In this double- blind placebo- controlled trial, cefazolin was given at skin incision (group A) or at cord clamping (group B). Patients were eligible for the trial if they had labored and required a cesarean delivery. Results: Over a 30- month period 303 patients with singleton pregnancies entered the trial; 153- group A, 149- group B. demographics, indication for cesarean delivery (P =. 54), and operative time (P =. 999), as well as rates of endometritis (RR 0.67, 95% CI 0.42- 1.07), wound infection (RR 0.84, 95% CI 0.45- 1.55), neonatal sepsis (RR 1.28, 95% CI 0.91- 1.79), and NICU admissions (RR 1.28, 95% CI 0.91- 1.79) were similar between the 2 groups. Conclusion: There was no difference in maternal infectious morbidity whether antibiotics were given before skin incision or at cord clamping.
