[Diversity of Zooplankton and Niche Characteristics of Keystone Species in the Weihe River Based on eDNA].

Environmental DNA(eDNA), a new tool for monitoring the biodiversity of aquatic ecosystems, is able to analyze characteristics of biodiversity from a microscopic perspective. Based on eDNA data collected from the Weihe River, diversity indexes, non-metric multidimensional scaling, cluster analysis, and correlation network analysis were employed to explore the diversity and community structure of zooplankton focusing on the niche differentiation of keystone species and environmental adaptability. The eDNA approach identified three types of zooplankton including Rotifera, Cladocera, and Copepoda, among which the dominant species was .

Combined Strategy for Post-Operative Patients with Central Nervous System Infections Caused by Extensively Drug-Resistant/Pan-Drug-Resistant : A Retrospective Study.

Post-operative central nervous system infections (PCNSIs) caused by extensively drug-resistant (XDR) or pan-drug-resistant (PDR) are rare but intractable problems. To investigate a potential combined strategy to treat organisms that are resistant to not only meropenem but also colistin. We retrospectively reviewed cerebrospinal fluid positive culture isolates of in patients who underwent neurosurgery.

, a new blind fish from the Three Gorges of Yangtze River provides insights into speciation of Chinese cavefish.

A blind fish of (Cypriniformes: Cyprinidae) was caught in open water in the Three Gorges (Sanxia) reservoir, at a depth of 20 m in the mainstream of Yangtze River in Zigui County, Hubei Province, China. This fish can be easily distinguished from all other congeners by external morphological characteristics, and is estimated to have diverged from its sister group about 0.55 million years ago (Ma).

[Advancement in Diagnosis and Treatment of Elevated Intracranial Pressure in Patients with Cryptococcal Meningitis].

Cryptococcal meningitis(CM)is often seen in immunocompromised patients and has become a global health concern. Elevated intracranial pressure(ICP)is a common complication of CM and often leads to poor prognosis. Monitoring and management of ICP is an important task in CM patients.

Prevalence and antibiotic resistance of bacteria isolated from the cerebrospinal fluid of neurosurgical patients at Peking Union Medical College Hospital.

Background: Postoperative central nervous system infections (PCNSIs) represent a serious complication, and the timely use of antibiotics guided by the identification of the causative pathogens and their antibiotic sensitivities is essential for treatment. However, there are little data regarding the prevalence of PCNSI pathogens in China. The aim of this study is to investigate the features of pathogens in patients with PCNSIs, which could help clinicians to choose the appropriate empirical antibiotic therapy.
