BACKGROUND: Percutaneous long-arm single-axis pedicle screw fixation and minimally invasive percutaneous single-plane pedicle screw internal fixation are both classical minimally invasive surgical options commonly used in clinical practice, but the two surgical methods in the treatment of thoracolumbar fractures are still controversial. OBJECTIVE: To compare the advantages and limitations of two procedures, long-arm single-axis pedicle screw percutaneous approach and minimally invasive percutaneous single-plane pedicle screw internal fixation, in the treatment of thoracolumbar fractures. METHODS: Ninety patients with thoracolumbar fractures admitted to Shenzhen Hospital of Guangzhou University of Chinese Medicine from March 2017 to June 2021 were included and assigned to the control group (n=45) and the trial group (n=45). The control group received minimally invasive percutaneous single-plane pedicle screw internal fixation. The trial group received long-arm single-axis pedicle screw percutaneous approach. The indexes related to perioperative general condition, pain level, and recovery were compared between the two groups. RESULTS AND CONCLUSION: (1) Compared with the control group, the trial group had less intraoperative blood loss, shorter operative time and hospital stay (P < 0.05). (2) At 2 weeks and 1 month after operation, Oswestry dysfunction index score and Cobb angle in the trial group were lower than those in the control group (P < 0.05). The anterior and posterior heights of the injured vertebra were higher in the trial group than those of the control group (P < 0.05). At 2 months after operation, the Oswestry dysfunction index score and Cobb angle in the trial group were lower than those in the control group (P < 0.05). There was no significant difference in the anterior and posterior heights of the injured vertebra between the two groups (P > 0.05). At 2 weeks after operation, the visual analog scale score was lower in the trial group than that in the control group (P < 0.05). (3) Among the 45 cases in the control group, there were 2 cases of incision infection, 2 cases of dyskinesia, and 1 case of implant-related adverse reactions, with a total incidence rate of 11%. Among the 45 cases in the trial group, there were 2 cases of dyskinesia, and the total incidence was 4%. There was no significant difference in the total incidence of complications between the two groups (P > 0.05). (4) Both long-arm single-axis pedicle screw percutaneous approach and minimally invasive percutaneous single-plane pedicle screw internal fixation can achieve better results in the treatment of thoracolumbar fractures. However, the former has shorter operative time and less intraoperative blood loss, so the former is the ideal surgical option for obtaining the same benefit. [ABSTRACT FROM AUTHOR]

Objective To investigate the protective effect of intraperitoneal injection of quercetin (QU) on retinal ischemia-reperfusion injury (RIRI) rats and its mechanism. Methods The random number method was used to divide 96 adult male SPF-grade rats without ocular disease into the control group (6 rats), the RIRI group (30 rats), the negative control group (30 rats), and the QU group (30 rats). At 7 consecutive days before modeling and 10 minutes before modeling, the rats in the QU group underwent the intraperitoneal injection of QU, the rats in the RIRI group underwent the intraperitoneal injection of an equal volume of normal saline, rats in the negative control group were intraperitoneally injected with an equal volume of DMSO, and rats in the control group were not treated. In addition to the control group, the ocular hypertension method was used to establish the RIRI models in the RIRI group, the QU group, and the negative control group. Rat retinal tissue specimens were prepared at 6, 12, 24, 48, and 72 h after modeling. Changes in the histomorphology of the rat retina were observed by hematoxylin-eosin (HE) staining, and the thickness of the inner layer of the rat retinal tissues was measured by a computerized image analysis system. Retinal apoptosis was observed by the TUNEL method. The expression of cysteine containing Caspase-3 was detected by immunohistochemistry. Results The retinal cells at each layer were normal in rats of the control group. The retinas of rats in the RIRI group and the negative control group showed a high degree of edema after 6 h of modeling; the number of ganglion cells in the retina was reduced and the arrangement of ganglion cells and inner nuclear layer cells was disorganized after 12 h of modeling; the edema of the retina was reduced after 24 h of modeling and the structure of the cells was further disrupted; and the edema of the retina was basically disappeared and the number of ganglion cells and inner nuclear layer cells was reduced after 48 h of modeling. The QU group had more intact retinal tissue structure and less cellular damage compared with the RIRI group and the negative control group at all time points. At 6 h and 12 h after modeling, the inner layer thickness of the retina was as follows: RIRI group, negative control group>QU group>control group, at 24 h, it was QU group>RIRI group, negative control group >control group, and at 48 and 72 h, it was control group>QU group>RIRI group, negative control group (all P<0. 05). In the control group, apoptotic cells and Caspase-3 positive cells were occasionally expressed in the rat retinal tissues. In the RIRI and negative control groups, the number of apoptotic cells and the number of Caspase-3 positive cells in the rat retinal tissues gradually increased at 6, 12, and 24 h of modeling, reached peak at 24 hs, and gradually decreased at 48 and 72 h. At each time point, the number of apoptotic cells and the number of caspase-3 positive cells in the rat retinal tissues of the QU group showed the same trend as that of the RIRI group and the negative control group, but the numbers were smaller than those of the RIRI group and the negative control group at the same time point (all P<0. 05). Conclusion Intraperitoneal injection of QU in rats has a certain protective effect against RIRI, and the mechanism may be related to the reduction of positive expression of Caspase-3 and inhibition of apoptosis.

To investigate the chemical constituents of Diaporthe tectonigena, a predominant endophytic fungus in the ancient tea tree of Camellia taliensis, the rice solid-state fermentation extract was isolated and purified by silica gel, Diaion HP20 and Sephadex LH-20 column chromatographies, and the chemical structures were elucidated by extensive HRMS, 1H-NMR, 13C-NMR, HSQC, HMBC and COSY spectroscopic analyses. The results were as follows: (1) Four compounds are isolated from the rice solid-state fermentation extract of Diaporthe tectonigena, including a new tetrahydro-β-carboline diketopiperazine alkaloid named tectonicgenazine A (1) . (2) Three known compounds, trans-cyclo- (D-tryptophanyl-L-tyrosyl) (2), 1H-indole-3-carboxylic acid-2,3-dihydroxypropyl ester (3) and N-hydroxyethyl-2-acetylpyrrole (4) were obtained and identified, and Compound 3 was isolated from nature for the first time.

为揭示单层球面网壳结构在静力均布荷载作用下的失稳模式与失效机理,预测结构可能发生的破坏模式和承载能力,基于双重非线性全过程分析理论,采用ANSYS软件对典型球面网壳结构开展稳定性参数分析,系统考察结构的荷载-位移全过程曲线、塑性发展分布、屈曲模态等特征响应。并以典型算例为代表,从宏观和微观两个方面诠释了单层球面网壳结构可能发生的3种失稳模式:弹性失稳、弹塑性提前失稳、弹塑性失稳。指出弹塑性提前失稳是由于结构强度破坏诱发的一类承载力偏低的失稳模式,为提高结构安全性,在网壳稳定性设计阶段中应避免出现此类失稳模式。

Extended Stöber method was adopted to prepare phenolic resin based carbon spheres, polyethylene glycol (PEG) with different adding amount and molecular weight were introduced in the synthesis process to modify the structure of prepared carbon spheres samples. The model fuel containing indole? quinoline and dibenzothiophene (DIED as target adsorbates were made. The effect of carbon spheres modification on the adsorptive performance of sulfur-containing and nitrogen-containing compound was investigated. The results showed that carbon spheres which were added proper amount of PEG had more developed microporous structure. The specific surface area of modified carbon sphere increased to 625 m2/g. The micropore volume also increased to 0. 235 m3/g? corresponding to the highest adsorptive capacity of 1.85 mmol/g for sulfur and nitrogen compounds. However, as the adding amount of PEG was further increased, larger micropores were formed in the carbon sphere, both specific surface area and micropore volume decreased, which would result in significantly decrease of adsorption capacity. Besides, PEG with larger molecular weight could lead to higher micropore volume and adsorption capacity of phenolic-resin based carbon sphere. [ABSTRACT FROM AUTHOR]
