004). Analysing the airway, subjects with a class II skeletal pattern had a smaller volume than those with a class III pattern (

= 0.034).

It may be concluded that skeletal class II patients have a significantly smaller airway volume than class III patients. The skeletal parameter does not always relate to the airway volume; however, the high mandibular angle could be related to the airway conditions.

The Tien Shan Mountain is one of the primary diversity centres of Tulipa, but the molecular studies of Tulipa species from this location are lacking. In our study, we assembled four Tulipa plastid genomes from the Tien Shan Mountains, T. altaica, T. iliensis, T. patens, and T. thianschanica, combined with the plastid genome of T. Shield1 sylvestris to compare against other Liliaceae plastid genomes. We focussed on the species diversity and evolution of their plastid genomes. The five Tulipa plastid genomes proved highly similar in overall size (151,691-152,088 bp), structure, gene order, and content. With comparative analysis, we chose 7 mononucleotide SSRs from the Tulipa species that could be used in further population studies. Phylogenetic analyses based on 24 plastid genomes robustly supported the monophyly of Tulipa and the sister relationship between Tulipa and Amana, Erythronium. T. iliensis, T. thianschanica, and T. altaica were clustered together, and T. patens was clustered with T. sylvestris, with our results clearly demonstrating the relationships between these five Tulipa species. Our results provide a more comprehensive understanding of the phylogenomics and comparative genomics of Tulipa.

To observe the changes in the mechanical withdrawal threshold (MWT) and the proportion of GABA-immunoreactive neurons in spinal dorsal horn (SDH) of the spared nerve injury (SNI) rat model.

Thirty-six healthy male SD rats were randomly divided into a sham-operated group (group D,

= 18) and an SNI group (group S,

= 18). The left sciatic nerve trunk and three branches were exposed, two of which, known as tibial and the peroneal nerve, were ligated and cut off. The sural nerve was preserved to build the SNI model in group S. The left sciatic nerve trunk and three branches were only exposed in group D. MWT tests were performed on the medial and lateral sides of the rats’ left hindpaw 1 day before surgery and at 7

, 14

, and 28

day after surgery.

In group S, compared with the baseline measured 1 day before surgery, MWT on the medial and lateral sides of the rats’ left hindpaw decreased significantly on the 7

, 14

, and 28

days after surgery (

< 0.05), while in group D, there was no statistically significant difference (

> 0.05). Compared with right SDH, there were not statistically significant reductions in the proportions of GABAergic neurons of left SDH on 7

and 28

day after SNI (

> 0.05); however, the proportion of GABAergic neurons in left SDH significantly decreased, compared with that in right side on 14

day after SNI (

< 0.05). On the same way, the proportions of GABAergic neurons on 7

, 14

, and 28

day after surgery were not statistically different (

> 0.05) in group D.

The SNI model could reduce the proportion of GABA-immunoreactive neurons in the rat’s spinal dorsal horn on the nerve-injured side, and this change was lasting, which might be related to the transformation of the GABA-immunoreactive neurons.

Polymicrobial

bloodstream infection (KP-BSI) has been reported to account for more than 10% of all KP-BSI, but few studies have characterized polymicrobial KP-BSI. Our study investigated the clinical characteristics, risk factors, and outcomes of polymicrobial KP-BSI by comparing with monomicrobial KP-BSI.

We conducted a single-center retrospective cohort study of patients with KP-BSI from 1 January 2013 to 31 December 2018 and collected the clinical data by reviewing electronic medical records.

Of the 818 patients with KP-BSI recruited, 13.9% (114/818) were polymicrobial KP-BSI. The severity of illness in polymicrobial and monomicrobial KP-BSI was similar, while the rate of resistance to carbapenems was obviously higher in polymicrobial KP-BSI (78.1% vs. 65.6%,

= 0.009). On multivariate analysis, hospitalization in burn ward (odds ratio (OR) 6.13, 95% confidence interval (CI) 2.00-18.76,

= 0.001) and intensive care unit (OR 2.39, 95% CI 1.05-5.43,

= 0.038) was independently associated with al KP-BSI.

It was observed that polymicrobial KP-BSI accounted for a significant proportion among all KP-BSI in the current study. Hospitalization in burn ward and intensive care unit was an independent risk factor for the development of polymicrobial KP-BSI. The patients with polymicrobial KP-BSI had a higher rate of carbapenem-resistant K. pneumoniae and might have poor outcomes compared to monomicrobial KP-BSI.

Parkinson’s disease (PD) patients are at increased risk for central auditory processing (CAP) deficits and cognitive dysfunction. However, behavioral assessments of CAP and cognitive processing used in a previous study by our research team found few significant differences in performance between early-stage PD patients and age-matched control subjects. The objective of this study is to use auditory event-related potentials (AERPs) to compare CAP and cognitive functions in a population of PD patients with a group of age-matched control subjects.

AERPs in response to tonal and speech stimuli were recorded from 35 adults who had a medical diagnosis of PD (23 males and 12 females; mean age = 66.9 ± s.d.11.2 years), and 35 age-matched control subjects who did not have PD or any other neurological disorders (31 males and 4 females; mean age = 65.4 ± s.d.12.3 years). Auditory stimuli included pure tones (500 and 1000 Hz) to elicit the P300 response and a dichotic digits paradigm to elicit the N200 processing negativity.
