Objective:To retrospectively observe the effect of oxycodone on acute postoperative pain in patients undergoing thoracoscopic surgery.Methods:A retrospective analysis was conducted on the clinical data of 404 patients undergoing thoracoscopic thoracic surgery under combined general anesthesia at the Xiangya Hospital, Central South University from April 1, 2020 to September 30, 2021. They were divided into A group ( n=99, oxycodone group) and B group ( n=305, control group) based on whether oxycodone was used during the surgery. The two groups of patients were further matched 1∶1 using the nearest neighbor matching method. We compared the Visual Analogue Scale (VAS) of activity and resting pain and the incidence of moderate to severe pain between two groups of patients 24 hours after surgery, and observed the incidence and severity of pain related adverse reactions such as nausea, vomiting, itching, and dizziness. Resultsl:After matching the propensity scores of the two groups of patients, the balance was good ( SMD<0.20). There was no statistically significant difference between the groups in age, gender, body mass index, American Society of Anesthesiologist (ASA) grade, surgical time, intraoperative bleeding, and the use of antiemetics and analgesics during the perioperative period (all P>0.05). Compared with the control group, patients in the group A had a resting VAS [(2.03±1.61)points vs (1.62±1.31)points, P=0.049], and activity VAS [(4.13±1.72)points vs (3.51±1.79)points, P=0.013] was even lower, and the incidence of moderate to severe pain (VAS≥4) during activity was lower [59.6%(59/99) vs 37.4%(37/99), P=0.003]. There was no statistically significant difference in the incidence of analgesic related adverse reactions between the two groups ( P>0.05). Conclusions:Intravenous injection of oxycodone can effectively alleviate acute pain in patients undergoing thoracoscopic surgery within 24 hours, and reduce the incidence of moderate to severe pain during activity.

Objective: To understand the incidence of stroke in the population of Jinchang Cohort and the relationship between metabolic diseases and stroke, and provide scientific evidence for the prevention and treatment of stroke in the population. Methods: The epidemiological investigation data and physical examination data of the 33 042 follow-up participants in Jinchang Cohort were collected for a prospective cohort study. Restricted cubic splines functions was used to analyze the dose-response relationship between metabolic indexes and the risk of stroke incidence. Results: 1) The incidence rate of stroke in Jinchang Cohort was 1.59%, and the standardized incidence rate was 3.99%. 2) Hypertension (male HR=2.20, female HR=4.45) and dyslipidemia (male HR=1.49, female HR=1.79) were the risk factors of stroke incidence in the population and diabetes had influence on the incidence of stroke only in the males (HR=1.79), while obesity had influence only in the females (HR=1.64). The more kinds of metabolic diseases, the higher risk of stroke incidence was. 3) Systolic blood pressure had a non-linear dose-response correlation with the risk of stroke incidence, while diastolic blood pressure had a positive linear correlation with the risk of stroke incidence. Conclusions The incidence of stroke in Jinchang Cohort population was high compared with both domestic level and oversea level. The patients with metabolic diseases were the population at high-risk for stroke, and more attention should be paid to them in the prevention and treatment of stroke. Diastolic blood pressure might be more closely related to stroke.

is famous for its important therapeutic effects. Saponins are bioactive compounds found in different parts and developmental stages of plants. Thus, it is urgently to study saponins distribution in different parts and growth ages of plants. In this study, potential biomarkers were found, and their chemical characteristic differences were revealed through metabolomic analysis. High-performance liquid chromatography data indicated the higher content of saponins (, Rg1, Re, Rd, and Rb1) in the underground parts than that in the aerial parts. 20()-Protopanaxadiol saponins were mainly distributed in the aerial parts. Additionally, the total saponin content in the 3-year-old plant (188.0 mg/g) was 1.4-fold higher than that in 2-year-old plant (130.5 mg/g). The transcriptomic analysis indicated the tissue-specific transcription expression of genes, namely, , , , , and , which encoded critical synthases in saponin biosyntheses. These genes showed similar expression patterns among the parts of plants. The expression levels of these genes in the flowers and leaves were 5.2fold higher than that in the roots and fibrils. These results suggested that saponins might be actively synthesized in the aerial parts and transformed to the underground parts. This study provides insights into the chemical and genetic characteristics of to facilitate the synthesis of its secondary metabolites and a scientific basis for appropriate collection and rational use of this plant.

The cultivation of plants is hindered by replanting problems, which may be caused by plant-driven changes in the soil microbial community. Inoculation with microbial antagonists may efficiently alleviate replanting issues. Through high-throughput sequencing, this study revealed that bacterial diversity decreased, whereas fungal diversity increased, in the rhizosphere soils of adult ginseng plants at the root growth stage under different ages. Few microbial community, such as , Cytophagaceae, , , Sphingomonadaceae, and Zygomycota, were observed; the relative abundance of microorganisms, namely, , Enterobacteriaceae, , Cantharellales, , , and Chytridiomycota, increased in the soils of adult ginseng plants compared with those in the soils of 2-year-old seedlings. 50-1, a microbial antagonist against the pathogenic , was isolated through a dual culture technique. These bacteria acted with a biocontrol efficacy of 67.8%. The ginseng death rate and abundance decreased by 63.3% and 46.1%, respectively, after inoculation with 50-1. Data revealed that microecological degradation could result from ginseng-driven changes in rhizospheric microbial communities; these changes are associated with the different ages and developmental stages of ginseng plants. Biocontrol using microbial antagonists alleviated the replanting problem.

The many-banded krait, Bungarus multicinctus, has been recorded as the animal resource of JinQianBaiHuaShe in the Chinese Pharmacopoeia. Characterization of its venoms classified chief phyla of modern animal neurotoxins. However, the evolutionary origin and diversification of its neurotoxins as well as biosynthesis of its active compounds remain largely unknown due to the lack of its high-quality genome. Here, we present the 1.58 Gbp genome of B. multicinctus assembled into 18 chromosomes with contig/scaffold N50 of 7.53 Mbp/149.8 Mbp. Major bungarotoxin-coding genes were clustered within genome by family and found to be associated with ancient local duplications. The truncation of glycosylphosphatidylinositol anchor in the 3'-terminal of a LY6E paralog released modern three-finger toxins (3FTxs) from membrane tethering before the Colubroidea divergence. Subsequent expansion and mutations diversified and recruited these 3FTxs. After the cobra/krait divergence, the modern unit-B of β-bungarotoxin emerged with an extra cysteine residue. A subsequent point substitution in unit-A enabled the β-bungarotoxin covalent linkage. The B. multicinctus gene expression, chromatin topological organization, and histone modification characteristics were featured by transcriptome, proteome, chromatin conformation capture sequencing, and ChIP-seq. The results highlighted that venom production was under a sophisticated regulation. Our findings provide new insights into snake neurotoxin research, meanwhile will facilitate antivenom development, toxin-driven drug discovery and the quality control of JinQianBaiHuaShe.
