A chromosome-level genome assembly for the desert scorpion Mesobuthus przewalskii from Asian drylands.

Scorpions are an ancient and charismatic group of arthropods with medical importance, but a high-quality reference genome for this group is still lacking. Here we perform whole-genome sequencing of Mesobuthus przewalskii, a desert scorpion endemic to the Taklimakan Desert. We combine PacBio HiFi sequencing and Hi-C chromosome conformation capturing to generate chromosomal-level, haplotype-resolved, and fully annotated genome assembly for this medically important scorpion.

Measurement Properties of the Simplified Chinese Version of the Lumbar Spine Instability Questionnaire for Patients With Low Back Pain in Mainland China.

Study Design: A prospective study.

Objective: To develop a simplified Chinese version of Lumbar Spine Instability Questionnaire (SC-LSIQ) and test its measurement properties.

Summary Of Background Data: The LSIQ has been translated into several languages.

Clinical Application of a Bird-Beak-Type Z-Shaped Asymmetrical Flap in the Reconstruction of the Inner Canthus.

Objective: To introduce a new surgical method for the repair of a large inner canthus combined with tissue loss at the inner canthal angle of the eye by using a bird-beak-type z-shaped asymmetrical flap and to summarize its clinical effect.

Method: A total of 56 patients with a large inner canthus were randomly selected, and a bird-beak-type z-shaped asymmetrical flap was used on the nasal side of the lower eyelid to repair and reconstruct the inner canthal folds. The inner canthal point was located according to physiological aesthetics.

Acupoint Specificity on Colorectal Hypersensitivity Alleviated by Acupuncture and the Correlation with the Brain-Gut Axis.

This project was focused on the study of the effect of the different acupoints on visceral hypersensitivity and the correlation with the brain-gut axis. By using a mouse model of zymosan-induced colorectal hypersensitivity, and observing the response of hypersensitivity model to colorectal distension stimulation in acupuncture at different acupoints, we selected the specific acupoints. With immunohistochemical staining method, we observed c-fos expression, distribution and changes after acupuncture on sensory pathway, including colorectum, spinal dorsal horn and different regions of brain center in the model with colorectal distension stimulation, and evaluated the acupuncture effect on brain-gut axis.

Acupoint specificity on acupuncture regulation of hypothalamic- pituitary-adrenal cortex axis function.

Background: The hypothalamus is an essential part of the brain that responds to a variety of signaling including stressful stimulations and acupuncture signals. It is also the key element of the hypothalamic-pituitary-adrenal cortex axis(HPAA). The effect of acupuncture is transmitted into the brain from the distance sensory receptor around the acupoints via peripheral nerves and body fluid.

Acupuncture Alleviates Colorectal Hypersensitivity and Correlates with the Regulatory Mechanism of TrpV1 and p-ERK.

Here we used a mouse model of zymosan-induced colorectal hypersensitivity, a similar model of IBS in our previous work, to evaluate the effectiveness of the different number of times of acupuncture and elucidate its potential mechanism of EA treatment. Colorectal distension (CRD) tests show that intracolonic zymosan injection does, while saline injection does not, induce a typical colorectal hypersensitivity. EA treatment at classical acupoints Zusanli (ST36) and Shangjuxu (ST37) in both hind limbs for 15 min slightly attenuated and significantly blunted the hypersensitive responses after first and fifth acupunctures, respectively, to colorectal distention in zymosan treatment mice, but not in saline treatment mice.
