ABSTRACT:Objective To investigate the effect and mechanism of anthocyanin on hepatic ischemia reperfusion injury in rats .Methods Totally 30 SD rats were randomly divided into sham group ,model group and anthocyanin group (n=10 in each) .Hepatic ischemia was constructed in model group and anthocyanin group by ligating left middle lobe of liver vascular branches for 90 min . Anthocyanin was administered at 90 min before ischemia by intraperitoneal injection at the concentration of 100 mg/kg for rats in anthocyanin group .Rats in model group and sham group were injected with the same dosage of normal saline at the same time .Serum and liver tissues were collected at 4 h after reperfusion by putting the rats to death .The expressions of ALT ,AST ,IL‐6 ,IL‐1βand TNF‐αin the serum were examined by ELISA .The pathological changes of liver tissue were evaluated by HE .The mRNA levels of IL‐6 ,IL‐1βand TNF‐αwere measured by RT‐PCR .The content of MDA was examined by TBA . The activities of CAT ,GPx and SOD were evaluated by xanthine oxidase method and the expression of p‐JAK2 ,p‐STAT3 ,JAK2 ,STAT3 and P53 were measured by Western blot .Results Compared with those in the sham group ,the activities of ALT and AST ,the expressions of p‐JAK2 ,p‐STAT3 ,P53 ,IL‐6 ,IL‐1β,TNF‐α and the content of MDA as well as the pathological changes of the liver in model group were significantly increased . However ,the activities of CAT ,GPx and SOD in model group were decreased and the expressions of JAK2 and STAT3 between the two groups did not differ .Compared with those in model group ,the activities of ALT and AST ,the expressions of p‐JAK2 ,p‐STAT3 ,P53 ,IL‐6 ,IL‐1β,TNF‐α,the content of MDA and the pathological changes of the liver in anthocyanin group were significantly decreased . But the activities of CAT , GPx and SOD in anthocyanin group were increased and the expressions of JAK 2 and STAT3 between the two groups did not differ , either .Conclusion Anthocyanin pretreatment can significantly decrease hepatic ischemia/reperfusion injury by suppressing oxidative stress and inflammation ,and the mechanism may be associated with reducing JAK2/STAT3/P53 signaling activation .

This study was aimed to explore the curative effect of Zhuo-Du-Qing (ZDQ) particles on diabetic cystopa-thy (DCP) based on the theory of turbid toxin. A total of 100 DCP patients were randomly divided into the control group with 47 cases and the treatment group with 53 cases. Mecobalamin tablets was given in the control group. And ZDQ particles were given to the treatment group. The treatment course was 3 months. The observation was made on the bladder residual urine (BRU), clinical manifestation integral, hemodynamic indexes, HOMA-IR and HbA1c before and after the treatment. The results showed that compared with pretreatment, the BRU, clinical manifestation integral, hemodynamic indexes, and HOMA-IR were significantly reduced (P < 0.01). Compared with the control group, the BRU, clinical manifestation integral, hemodynamic indexes, and HOMA-IR were also significantly reduced (P <0.01). The effective rate in the treatment group was 81.1%, which was significantly higher than 59.6% in the control group (P< 0.05). There were no obvious changes on the blood routine examination, urine routine examination, stool routine examination, liver function, renal function, electrocardiogram and so on before and after treatment. It was con-cluded that the treatment of DCP with ZDQ particles was safe and effective. To remove toxin and descend turbid may be another effective treatment method for DCP. The occurrence and development of DCP were closely related to the turbid toxin.

ObjectiveTo explore the intervention effect and molecular mechanism of Dabufei decoction in Dunhuang formula combined with cisplatin on Lewis lung adenocarcinoma-bearing mice. MethodFifty C57BL/6J mice were used, with 10 randomly assigned to the blank group (without modeling), and 40 subcutaneously inoculated with Lewis cells to establish a Lewis lung adenocarcinoma-bearing mouse model. These 40 mice were randomly divided into the following four groups (with 10 mice in each group): Model group (equal volume of physiological saline), cisplatin group (5 mg·kg-1), Dabufei decoction group (14.35 g·kg-1·d-1), and Dabufei decoction combined with cisplatin group (Dabufei decoction 14.35 g·kg-1·d-1 + cisplatin 5 mg·kg-1). Each group was treated continuously for 14 days. The general condition of the mice was observed, body weight changes were recorded, and the tumor inhibition rate, spleen index, and thymus index were calculated. Peripheral blood white blood cell (WBC), platelet (PLT), and hemoglobin (HGB) were detected by routine blood tests. Flow cytometry was used to detect the expression of CD4+CD25+FoxP3+ regulatory T cells (Treg) and natural killer (NK) cells in the spleen. Western blot and real-time quantitative polymerase chain reaction (Real-time PCR) were used to determine the expression of proteins and mRNA related to the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR) signaling pathway in tumor tissues. ResultCompared with the blank group, the model group showed decreased body weight (P<0.05), spleen index, and thymus index (P<0.05), decreased percentage of NK cells in the spleen (P<0.05), increased percentage of Treg cells (P<0.05), and decreased counts of WBC, PLT, and HGB (P<0.05). Compared with the model group, the Dabufei decoction group exhibited significant tumor growth inhibition, increased body weight, and reduced tumor weight (P<0.05), increased percentage of NK cells (P<0.05), decreased proportion of Treg cells (P<0.05), and increased counts of WBC, PLT, and HGB (P<0.05). In the cisplatin group, tumor growth was significantly inhibited, body weight significantly decreased (P<0.05), and tumor weight significantly reduced (P<0.05). The spleen index and thymus index decreased (P<0.05), and the percentage of Treg cells significantly decreased (P<0.05). The counts of WBC, PLT, and HGB significantly decreased (P<0.05). In the Dabufei decoction combined with cisplatin group, tumor growth was significantly inhibited, and tumor weight significantly reduced (P<0.05). The levels of phosphorylated PI3K, Akt, and mTOR proteins and mRNA in tumor tissues were significantly reduced in all medication groups (P<0.05). Compared with the cisplatin group, the Dabufei decoction combined with cisplatin group showed significantly inhibited tumor growth, reduced tumor weight (P<0.05), increased body weight (P<0.05), increased spleen index and thymus index (P<0.05), increased percentage of NK cells (P<0.05), decreased percentage of Treg cells (P<0.05), significantly increased counts of WBC, PLT, and HGB (P<0.05), and reduced levels of phosphorylated PI3K, Akt, and mTOR and their mRNA (P<0.05). ConclusionDabufei decoction combined with cisplatin has a synergistic effect with reduced toxicity, effectively regulating immune function, increasing the proportion of NK cells, reducing the proportion of Treg cells, improving bone marrow suppression, and downregulating the PI3K/Akt/mTOR signaling pathway to inhibit tumor growth in Lewis lung adenocarcinoma-bearing mice.

cFos is one of the most widely-studied genes in the field of neuroscience. Currently, there is no systematic database focusing on cFos in neuroscience. We developed a curated database-cFos-ANAB-a cFos-based web tool for exploring activated neurons and associated behaviors in rats and mice, comprising 398 brain nuclei and sub-nuclei, and five associated behaviors: pain, fear, feeding, aggression, and sexual behavior. Direct relationships among behaviors and nuclei (even cell types) under specific stimulating conditions were constructed based on cFos expression profiles extracted from original publications. Moreover, overlapping nuclei and sub-nuclei with potentially complex functions among different associated behaviors were emphasized, leading to results serving as important clues to the development of valid hypotheses for exploring as yet unknown circuits. Using the analysis function of cFos-ANAB, multi-layered pictures of networks and their relationships can quickly be explored depending on users' purposes. These features provide a useful tool and good reference for early exploration in neuroscience. The cFos-ANAB database is available at www.cfos-db.net .

Esophageal squamous-cell carcinoma (ESCC) is one of the most lethal malignancies in the world and occurs at particularly higher frequency in China. While several genome-wide association studies (GWAS) of germline variants and whole-genome or whole-exome sequencing studies of somatic mutations in ESCC have been published, there is no comprehensive database publically available for this cancer. Here, we developed the Chinese Cancer Genomic Database-Esophageal Squamous Cell Carcinoma (CCGD-ESCC) database, which contains the associations of 69,593 single nucleotide polymorphisms (SNPs) with ESCC risk in 2022 cases and 2039 controls, survival time of 1006 ESCC patients (survival GWAS) and gene expression (expression quantitative trait loci, eQTL) in 94 ESCC patients. Moreover, this database also provides the associations between 8833 somatic mutations and survival time in 675 ESCC patients. Our user-friendly database is a resource useful for biologists and oncologists not only in identifying the associations of genetic variants or somatic mutations with the development and progression of ESCC but also in studying the underlying mechanisms for tumorigenesis of the cancer. CCGD-ESCC is freely accessible at http://db.cbi.pku.edu.cn/ccgd/ESCCdb.
