[Scenario Simulation and Effects Assessment of Co-control on Pollution and Carbon Emission Reduction in Beijing].

Focused on the key areas of energy, buildings, industry, and transportation, with 2020 as the base year and 2035 as the target year, we respectively designed the baseline scenario, policy scenario, and enhanced scenario, calculated the emission reduction potential of air pollutants and CO of Beijing, and constructed an assessment method of co-control effect gradation index to evaluate the co-control effect of air pollutants and CO in the policy scenario and enhanced scenario. The results showed that in the policy scenario and enhanced scenario, the reduction rates of air pollutants emissions will reach 11%-75% and 12%-94%, respectively, and reduction rates of CO emissions will reach 41% and 52%, respectively, compared with those from the baseline scenario. Optimizing vehicle structure had the largest contribution to the emission reduction of NO, VOCs, and CO, and the emission reduction rates will reach 74%, 80%, and 31% in the policy scenario and 68%, 74%, and 22% in the enhanced scenario, respectively.

Synthesis and Evaluation of Novel 2H-Benzo[e]-[1,2,4]thiadiazine 1,1-Dioxide Derivatives as PI3Kδ Inhibitors.

In previous work, we applied the rotation-limiting strategy and introduced a substituent at the 3-position of the pyrazolo [3,4-]pyrimidin-4-amine as the affinity element to interact with the deeper hydrophobic pocket, discovered a series of novel quinazolinones as potent PI3Kδ inhibitors. Among them, the indole derivative 3 is one of the most selective PI3Kδ inhibitors and the 3,4-dimethoxyphenyl derivative 4 is a potent and selective dual PI3Kδ/γ inhibitor. In this study, we replaced the carbonyl group in the quinazolinone core with a sulfonyl group, designed a series of novel 2-benzo[][1,2,4]thiadiazine 1,1-dioxide derivatives as PI3Kδ inhibitors.

[Effects of Tongbi capsule on joint lesions in rabbits with rheumatoid arthritis].

The purpose of this experiment is to observe the effects of Tongbi capsule on joint lesions in rabbit with rheumatoid arthritis induced by ovalbumin and explore the mechanism in order to provide reference for clinical application of Tongbi capsule. Rheumatoid arthritis in rabbits was induced by subcutaneous injection of emulsions of ovalbumin and Freund's complete adjuvant and intra articular injection of ovalbumin. After successful modeling, 30 New Zealand rabbits with arthritis were randomly divided into model control group, the high, medium and low dose groups of Tongbi capsule (90, 45, 22.

Evaluation of the effect of glutathione on cisplatin antitumor activity and kidney injury at different administration times.

Cisplatin (cis-diamminedichloroplatinum, CDDP) is one of the most potent anticancer drugs. However, the therapeutic value of CDDP is greatly compromised by its dose-limiting nephrotoxicity. This study was performed to investigate whether reduced glutathione (GSH) was able to reduce the kidney injury induced by CDDP and whether it affected the anticancer activity of CDDP in vivo and in vitro.

[Effect of electroacupuncture on proliferation of astrocytes after spinal cord injury].

Objective: To explore the mechanism of acupuncture in treatment of spinal cord injury (SCI).

Methods: Adult Wistar rats were used to make SCI model by Allen's method. The SCI rats were treated with electroacupuncture (EA) at acupoints of the Governor Vessel for 3 days, 1 week, 2 weeks or 4 weeks.
