Light-Driven C-C Coupling for Targeted Synthesis of CH3 COOH with Nearly 100 % Selectivity from CO2.

Targeted synthesis of acetic acid (CH3 COOH) from CO2 photoreduction under mild conditions mainly limits by the kinetic challenge of the C-C coupling. Herein, we utilized doping engineering to build charge-asymmetrical metal pair sites for boosted C-C coupling, enhancing the activity and selectivity of CO2 photoreduction towards CH3 COOH. As a prototype, the Pd doped Co3 O4 atomic layers are synthesized, where the established charge-asymmetrical cobalt pair sites are verified by X-ray photoelectron spectroscopy and X-ray absorption near edge spectroscopy spectra. Theoretical calculations not only reveal the charge-asymmetrical cobalt pair sites caused by Pd atom doping, but also manifest the promoted C-C coupling of double *COOH intermediates through shortening of the coupled C-C bond distance from 1.54 to 1.52 Å and lowering their formation energy barrier from 0.77 to 0.33 eV. Importantly, the decreased reaction energy barrier from the protonation of two*COOH into *CO intermediates for the Pd-Co3 O4 atomic layer slab is 0.49 eV, higher than that of the Co3 O4 atomic layer slab (0.41 eV). Therefore, the Pd-Co3 O4 atomic layers exhibit the CH3 COOH evolution rate of ca. 13.8 µmol g-1 h-1 with near 100% selectivity, both of which outperform all previously reported single photocatalysts for CO2 photoreduction towards CH3 COOH under similar conditions.

The role of IL-6, IL-10, and PGE2 in the treatment of intervertebral disc herniation by dual-channel endoscopic lumbar discectomy.

is the This study aimed to explore the role of IL-6, IL-10, and PGE2 in the treatment of intervertebral disc herniation with dual-channel endoscopic lumbar discectomy. For this purpose, we selected 182 patients with intervertebral disc herniation in our hospital and randomly divided them into the control group and the study group according to the order of admission, of which 85 cases were in the control group, 97 cases in the study group, and control group was treated with conventional lumbar discectomy; the study group was treated with dual-channel spine endoscopic lumbar discectomy to observe and compare the operation-related indexes, lumbar function indexes, clinical effects, serum-related indexes and the evaluation value of the two groups of patients. Results showed that the operation time, incision length, intraoperative blood loss, hospital stay, and postoperative pain scores of the study group were lower than those of the control group (p<0.05); the ODI and RMQ scores of the study group after treatment were lower than those of the control group (P<0.05). The excellent and good rate of the study group was 89.69% higher than that of the control group 77.65% (p<0.05); the levels of IL-6 and PGE2 in the study group after treatment were lower than those of the control group, and the IL-10 level was higher than that of the control group. (P<0.05); Using the lumbar spine function score as the comparison standard: IL-6, IL-10, PGE2 for the evaluation value of dual-channel endoscopic lumbar discectomy for the treatment of intervertebral disc herniation: sensitivity 96.18%, specificity 96.27%, the accuracy of 97.06% was higher than the single diagnosis result (P<0.05. It is worthy of clinical promotion. IL-6, IL-10, PGE2 predict dual-channel spine Endoscopic lumbar discectomy for the treatment of intervertebral disc herniation has high prognostic sensitivity and accuracy, which can provide references for clinical treatment and prognostic medication.

The effect of locating and sliding of facet combined with percutaneous endoscopic lumbar discectomy on cell inflammatory indicators and the treatment of disc herniation.

This study aimed to investigate the effects of IL-8, CRP and TXB2 in the treatment of lumbar disc herniation by combining with percutaneous endoscopic discectomy. For this purpose, 290 patients with disc herniation were selected as the research objects and randomly divided into two groups. The control group was treated with traditional intervertebral fenestration of nucleus pulposus, and the research group was treated with joint process location slip technique combined with percutaneous endoscopic lumbar disc discectomy. The clinical efficacy, functional scores and serological indexes of the two groups were compared, and the prognostic value of IL-8, CRP and TXB2 in the treatment of disc herniation by the combination of the sliding technique of facet location and percutaneous endoscopic discectomy was explored. The results showed that the total effective rate of 95.55% in the study group was higher than 79.31% in the control group, and the difference was significant (P<0.05). The operative time, incision length, length of hospital stay and intraoperative blood loss in the study group were lower than those in the control group (P<0.05). JOA score was higher and ODI score was lower in the two groups after surgery than before surgery, and JOA score in the study group was higher than that in the control group, while the ODI score was lower than that in the control group (P<0.05). Il-8, CRP and MDA in 2 groups increased after the operation, while SOD and TXB2 decreased significantly. Il-8, CRP, TXB2 and SOD in the study group were lower than those in the control group, while MDA was higher than those in the control group (P<0.05). ROC curve indicated that the areas under the curves of IL-8, CRP and TXB2 were 0.725, 0.835 and 0.880, and the areas under the curves, sensitivity and specificity of the combined determination were higher than those of any index (P<0.05). In general, compared with traditional interlaminar fenestration of nucleus pulposus, combined with percutaneous endoscopic lumbar disc discectomy has a significant effect on the treatment of disc herniation, and can reduce the levels of IL-8, CRP and TXB2.
