Purpose: The purpose of this study was to examine how green credit loans affect the credit risk of commercial banks in China. The heterogeneity of banks was analyzed, and the synergy with the equity capital ratio was analyzed more innovative in consideration of the impact of the government’s regulatory policy on green credit loans. Research design, data, and methodology: This study focuses on the influence of green credit on the risk of commercial banks in China. Using the sample data of 16 relatively large commercial banks in China from 2009 to 2019, this paper constructs a static panel data model for empirical analysis. Results: First, The results show that the green credit business can significantly reduce the non-performing loan ratio (NPLR) of banks. Second, We found that the green credit ratio (GCR) is positively correlated with the NPLR namely, the green credit ratio and credit risk show a "U-shaped" relationship between credit risk and "pre-down, post-up". Third, The impact of green credit on the credit risk of non-state-owned banks is significantly reduced, while the impact on the credit risk of state-owned commercial banks is not significant, Finally, In view of the interaction of capital adequacy ratio(CAR) and green credit on bank credit risk, we find that banks with higher capital adequacy ratio have a more positive effect on reducing credit risk. Implications: Commercial banks that develop the green credit have risk consideration, especially credit risk. It should be noted that risk management considerations are important for the stability of the banking system. This study provides empirical evidence for commercial banks to reduce the credit risk. The results of this study are helpful in actively promoting China’s green credit loan policy.

IFN-${\gamma}$ plays an indirect anti-cancer role through the immune system but may have direct negative effects on cancer cells. It regulates the viability of gastric cancer cells, so we examined whether it affects their proliferation and how that might be brought about. We exposed AGS, HGC-27 and GES-1 gastric cancer cell lines to IFN-${\gamma}$ and found significantly reduced colony formation ability. Flow cytometry revealed no effect of IFN-${\gamma}$ on apoptosis of cell lines and no effect on cell aging as assessed by ${\beta}$-gal staining. Microarray assay revealed that IFN-${\gamma}$ changed the mRNA expression of genes related to the cell cycle and cell proliferation and migration, as well as chemokines and chemokine receptors, and immunity-related genes. Finally, flow cytometry revealed that IFN-${\gamma}$ arrested the cells in the G1/S phase. IFN-${\gamma}$ may slow proliferation of some gastric cancer cells by affecting the cell cycle to play a negative role in the development of gastric cancer.

Cadmium telluride quantum dots (QDs) have received significant attention in biomedical research because of their potential in drug delivery. In this study, the chemotherapeutic agent Verbascoside (VB) was immobilized successfully onto CdTe QDs by covalent bonding between the –OH group of VB and the –COOH group of CdTe QDs. The amount of VB that could be immobilized depended on the concentration of –COOH groups (succinic acid) on the surface of the CdTe QDs. Apoptotic staining, DNA fragmentation and flow cytometry analysis further demonstrated that compared with CdTe QDs or VB treatment alone, the apoptosis rate increased after the treatment of CdTe QDs together with VB (VB–QDs) in HepG2/ADM cells. We observed that VB–QDs treatment could clearly activate apoptosis-related Caspase 3 expression in HepG2/ADM cells. Moreover, our in vivo study indicated that the treatment of VB–QDs effectively inhibited the human hepatoma HepG2/ADM nude mice tumor growth. The increased cell apoptosis rate was closely correlated with the enhanced inhibition of tumor growth in the studied animals. Thus, VB–QDs may serve as a possible alternative for therapeutic approaches for some cancer treatments. In summary, studies have shown that cancer cells are treated by the presence of VB–QDs nanoparticles based on analysis of cell apoptosis.

Purpose The evidence of adherence to cancer prevention guidelines and endometrial cancer (EC) risk has been limited and controversial. This study summarizes and quantifies the relationship between adherence to cancer prevention guidelines and EC risk. Materials and Methods The online databases PubMed, Web of Science, and EMBASE were searched for relevant publications up to June 2, 2020. This study had been registered at PROSPERO. The registration number is CRD42020149966. Study quality evaluation was performed based on the Newcastle-Ottawa Scale. The I2 statistic was used to estimate heterogeneity among studies. Egger’s and Begg’s tests assessed potential publication bias. Summary hazard ratios (HRs) and 95% confi dence intervals (CIs) for the relationship between adherence to cancer prevention guidelines score was assigned to participants by summarizing individual scores for each lifestyle-related factor. The scores ranged from least healthy (0) to most healthy (20) and the EC risk was calculated using a random-effects model. Results Five prospective studies (four cohort studies and one case‑cohort study) consisted of 4,470 EC cases, where 597,047 participants were included. Four studies had a low bias risk and one study had a high bias risk. Summary EC HR for the highest vs. lowest score of adherence to cancer prevention guidelines was 0.54 (95% CI, 0.40 to 0.73) and had a high heterogeneity (I2=86.1%). For the dose-response analysis, an increment of 1 significantly reduced the risk of EC by 6%. No signifi cant publication bias was detected. Conclusion This study suggested that adherence to cancer prevention guidelines was negatively related to EC risk.

The calpain I (CAPN1) gene is an important marker for meat tenderness and marbling score in the bovine, but there were no studies to determine whether the CAPN1 gene had an association with other meat quality traits. In this study, we examined the relation between genetic polymorphisms of the CAPN1 gene and some meat quality traits in Yanbian Yellow Cattle of China. By PCRSSCP and gene sequencing in 321 unrelated Yanbian yellow cattle, twenty seven single nucleotide polymorphisms (SNPs) were detected in CAPN1, two existed SNPs in exon 8 and exon 17 resulted in the change of AA at F311S and M599V, respectively, and the otherpolymorphisms were at intron 7, 8, 14, 16 and 17. There were different preponderant genotypes at the corresponding gene locus and all genotypes were not associated with tenderness but other meat traits. This is the first study of the relationship between CAPN1 and meat quality besides tenderness in Yanbian yellow cattle of China.

Trichoderma harzianum ZF-2 producing laccase was isolated from decaying samples from Shandong, China, and showed dye decolorization activities. The objective of this study was to optimize its culture conditions using a statistical analysis of its laccase production. The interactions between different fermentation parameters for laccase production were characterized using a Plackett-Burman design and the response surface methodology. The different media components were initially optimized using the conventional one-factor-at-atime method and an orthogonal test design, and a Plackett-Burman experiment was then performed to evaluate the effects on laccase production. Wheat straw powder, soybean meal, and CuSO4 were all found to have a significant influence on laccase production, and the optimal concentrations of these three factors were then sequentially investigated using the response surface methodology with a central composite design. The resulting optimal medium components for laccase production were determined as follows: wheat straw powder 7.63 g/l, soybean meal 23.07 g/l, (NH4)2SO4 1 g/l, CuSO4 0.51 g/l, Tween-20 1 g/l, MgSO4 1 g/l, and KH2PO4 0.6 g/l. Using this optimized fermentation method, the yield of laccase was increased 59.68 times to 67.258 U/ml compared with the laccase production with an unoptimized medium. This is the first report on the statistical optimization of laccase production by Trichoderma harzianum ZF-2.
