Abstract	The Hoabinhian is the most representative technocomplex in Southeast Asian prehistory for the later hunter–gatherer period. As a mainland technology based exclusively on seasonal tropical environments, this core-tool culture was previously defined in northern Vietnam in 1932 and characterized originally by its large, flat and long, largely unifacial cobble tools associated with tropical forest fauna. The recent discoveries and dates obtained at Xiaodong rockshelter in Yunnan Province (southwest China) allow us to discuss the origin and the homeland of this singular Asian technocomplex which spread to Southeast Asia during the end of the Late Upper Pleistocene. Here we present the first Chinese Hoabinhian lithic implements in their stratigraphic and chronological context within a rockshelter site, and we address the question of the dispersal of modern humans from South China to Southeast Asia.

Abstract	The NWW-striking Qinling Orogen formed in the Triassic by collision between the North China and Yangtze Cratons. Triassic granitoid intrusions, mostly middle- to high-K, calc-alkaline in composition, are widespread in this orogen, but contemporaneous intrusions are rare in the southern margin of the North China Craton, an area commonly considered as the hinterland belt of the orogen. In this paper, we report zircon U-Pb ages, elemental geochemistry, and Sr-Nd-Hf isotope data for the Laoniushan granitoid complex that was emplaced in the southern margin of the North China Craton. Zircon U-Pb dating shows that the complex was emplaced in the late Triassic (228±1 to 215±4 Ma), indicating that it is part of the post-collisional magmatism in the Qinling Orogen. The complex consists of, from early to late, biotite monzogranite, quartz diorite, quartz monzonite, and hornblende monzonite, which have a wide compositional range, e.g., SiO2=55.9-70.6 wt%, K2O+Na2O=6.6-10.2 wt%, and Mg# of 24 to 54. Rocks of the biotite monzogranite have high Al2O3(15.5-17.4 wt%), Sr(396-1398 ppm) and Ba(1284-3993 ppm) contents and La/Yb(mostly 14-30) and Sr/Y(mostly 40-97) ratios, but low Yb(mostly 1.3-1.6 ppm) and Y(mostly14-19 ppm) contents, features typical of adakite. The quartz monzonite, hornblende monzonite and quartz diorite have a shoshonitic affinity, with K2O up to 5.58 wt% and K2O/Na2O ratios averaging 1.4. The rocks are characterized by strong LREE/HREE fractionation in chondrite-normalized REE pattern, without obvious Eu anomalies, and show enrichment in large ion lithophile elements but depletion in high field strength elements (Nb, Ta, Ti). The biotite monzogranite (228 Ma) has initial 87Sr/86Sr ratios of 0.7061 to 0.7067, eNd(t) values of -9.2 to -12.6, and ?Hf(t) values of -9.0 to -15.1; whereas the shoshonitic granitoids (mainly 217-215 Ma) have similar initial 87Sr/86Sr ratios (0.7065 to 0.7075) but more radiogenic eNd(t) (-12.4 to -17.0) and eHf(t) (-14.1 to -17.0). The Sr-Nd-Hf isotope data indicate that the rocks were likely generated by partial melting of an ancient lower continental crust with heterogeneous compositions, as partly confirmed by the widespread presence of the early Paleoproterozoic inherited zircons. Mafic microgranular enclaves (MMEs), characterized by fine-grained igneous textures and an abundance of acicular apatites, are common in the Laoniushan complex. Compared with the host rocks, they have lower SiO2 (48.6-53.7 wt.%) and higher Mg# (51-56), Cr (122-393 ppm), and Ni (24-79 ppm), but equivalent Sr-Nd isotope compositions, indicating that the MMEs likely originated from an ancient enriched lithospheric mantle. The abundance of MMEs in the granitoid intrusions suggests that magma mixing plays an important role in the generation of the Laoniushan complex. Collectively, it is suggested that the Laoniushan complex was a product of post-collisional magmatism related to lithospheric extension following slab break-off. Formation of the adakitic and shoshonitic intrusions in the Laoniushan complex indicates that the Qinling Orogen had evolved into a post-collisional setting by about 230-210 Ma.

Abstract	Carbon emission trading policy (CETP) is an important tool for energy savings and emission reduction. However, the effect of CETP on carbon emission reduction in power industry is still unknown. This paper uses the difference-in-differences (DID) model and the intermediary effect model to test the impact and mechanism of CETP on power industry carbon emissions. In addition, a spatial difference-in-differences (SDID) model is established to analyze the spatial spillover effect. The results show that CETP has a significant inhibitory effect on power industry carbon emissions and the results are still valid after endogenous and robust tests. The improvement of technology level and power conversion efficiency plays an intermediary role for CETP to reduce power industry carbon emissions. The optimization of power generation structure is likely to become another important way for CETP to play its role in the future. The spatial spillover effect test shows that CETP not only has a significant inhibitory effect on power industry carbon emissions in the pilot areas but also has a negative spatial spillover effect on power industry carbon emissions in the surrounding non-pilot areas. The heterogeneity tests show that CETP has the most significant reduction effect in the central region of China and the strongest spatial spillover inhibiting effect in the eastern region. The purpose of this study is to provide decision-making references for government to achieve China's dual-carbon goal.

Abstract	More and more emphasis is placed on the common development of economy and ecological environment in China’s development strategy, and one of the key solution is green technology innovation of enterprises. This paper takes the carbon emission trading scheme carried out in China in 2013 as a quasi-natural experiment and uses the data of China’s A-share non-financial listed companies and the DID method to empirically test the impact of the scheme on enterprise green technology innovation from the micro level. The results suggest that the carbon emission trading scheme has a significant role in promoting enterprise green technology innovation, mainly through the innovation of green practical patents and alternative energy-based patent. Using a series of robustness tests such as dynamic effect test, placebo test, and PSM-DID, it is found that the results are still valid. Further analysis finds that debt financing will weaken the role of carbon emission trading scheme in promoting enterprise green technology innovation. And the carbon emission trading scheme plays a greater role in promoting green technology innovation in state-owned enterprises, enterprises belonging to areas with strong pollution control intensity and high pollution industry.

Abstract	Objective To investigate the relationship between the expression of CXC chemokine ligand 8 (CXCL8) and miR-150 in the skin lesions of patients with psoriasis vulgaris and the severity of the disease. Methods The skin lesions of 80 patients with psoriasis vulgaris who were treated in Nanyang first people's Hospital from January 2020 to May 2021 were selected as the research objects. The normal tissues around the skin lesion were chosen as a control. The Psoriasis Area and Severity Index (PASI) was used to classify patients with psoriasis, the immunohistochemical method was used to detect the expression of CXCL8 protein, the real time fluorescence quantitative PCR method was used to detect the expression of miR-150, Western blot was used to detect the expression of CXCL8 protein, and the correlation between the expression levels of CXCL8 protein, miR-150 and the severity of the disease was further analyzed. Results The level of CXCL8 mRNA in the skin lesion of patients with psoriasis vulgaris was higher than that in normal tissues (P＜0.05) and the level of miR-150 was lower than that in normal tissues(P＜0.05). The expression of CXCL8 protein in the skin lesions of patients was 68.75%, which was significantly higher than 37.50% in normal tissues (P＜0.05); the expression of CXCL8 protein in the skin lesions of patients was significantly higher than that in normal tissues (P＜0.05); the level of miR-150 gradually decreased with the aggravation of the disease (P＜0.05), and the level of CXCL8 protein gradually increased with the aggravation of the disease (P＜0.05); Pearson results showed that there was a negative correlation between miR-150 level in patients with psoriasis vulgaris and CXCL8 protein level and PASI score (r=-0.467, -0.475, P＜0.05), and there was a positive correlation between CXCL8 protein level and PASI score (r=0.424, P＜0.05). Conclusions The expression of miR-150 decreased and CXCL8 increased in patients with psoriasis vulgaris, both of them were related to the severity of the disease.
