ve To understand the impacts of industrial fluoride-induced pollution on environment and human health. Methods The contents of fluorides in environmental media, such as air, soil, vegetables, weeds, branches and leaves in area around a certain chemical factory (polluted area) were monitored. The prevalance of dental fluorosis, the contents of fluorides in hair and nail were investigated among 87 individuals without history of exposure to industrial fluorides, living in polluted area for more than 5 years, and 132 individuals in control area. Results Higher fluoride levels in environmental medias, higher prevalance rates of dental fluorosis, high contents of fluorides in hair and nails of population were found in polluted area compared with those in control area. Conclusion The in-dustrial fluoride-induced pollution from this chemical factory had resulted in the hazardous impacts on environmental quality and human health.

24 days in mm, V1:the degree of expansion in ml) had linear correlation, E1=(0.86V1?0.60) mm. Conclusion The results of the study demonstrate that CT is an accurate and reliable imaging technique in the evaluation of the degree of expansion of the injured orbit and in the prediction of the possibility of the consequent enophthalmos and its degree. It is significantly helpful to the therapeutic planning for the quantity the retroglobal filling in the rectification of the enophthalmos.

In order to explore the effects of testicular infection of murine cytomegalovirus (MCMV) on mature sperm viability at different periods following MCMV inoculation in mice, 91 BALB/c mice without MCMV infection were randomly divided into two groups: an experimental group (n = 56) and a control group (n = 35). The mice in the experimental group were treated by inoculating MCMV intratesticularly, while those in the controlled group were directly inoculated with DMEM without MCMV. The mice in both groups were sacrificed separately on the day 1, 1. 5, 2, 4, 6, 9 and 14 post-inoculation (D1) 1. 5, 2, 4, 6, 9 and 14 PI). The MCMV M83 mRNA gene was detected in the testis by in situ hybridization (ISH) with MCMV late-mRNA probe labeled with digoxin. Sperm viability of mature sperm in the epididymis cauda was measured. The results demonstrated the positive signal of ISH of MCMV was found mainly in the cytoplasm of the testicular interstitial cells and spermatogenic cells in the experimental group. Compared with that in the controlled group, the sperm viability in the experimental group was decreased significantly on D1 PI and D1.5 PI (P < 0.05). No statistically significant difference in the sperm viability was found after D2 PI between two groups (P > 0.05). This suggested that sperm viability in mice might be descended significantly shortly after MCMV infection and might return to normal with time, indicating that MCMV acute infection might temporarily degrade sperm quality and influence procreation transiently.

We predicted the anti-ulcerative colitis (UC) mechanism of Fructus Amomi based on network pharmacology. The anti-UC activity of Fructus Amomi were investigated by in vivo animal experiment, and the active components of Fructus Amomi were obtained through TCMSP, PubChem database and literature research. Animal welfare and experimental procedures follow the regulations of the Animal Ethics Committee of Institute of Materia Medica of Chinese Academy of Medical Sciences. The potential targets of the active components and UC were predicted by SwissTargetPrediction, GeneCards and TTD databases. The protein-protein interaction (PPI) network was constructed by String database and Cytoscape software was used to construct a visual network of active component-disease target and perform topological analysis. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed using Metascape platform. The molecular docking of key components and core targets was carried out by Sybyl X software. We screened out a total of 12 active components and 189 disease-component overlapping targets. Enrichment analyses obtained 227 related GO items and 168 signaling pathways. According to the results of molecular docking, most active components of Fructus Amomi showed good affinity with the JAKs receptor family. Furthermore, Western blot results verified that Fructus Amomi could effectively inhibit JAK/STAT signaling pathway, indicating that Fructus Amomi might exert the anti-UC activity by regulating JAK/STAT signaling pathway.

Colorectal cancer is a common malignant tumor in the gastrointestinal tract, with the characteristics of high morbidity and mortality. Studies have shown that the occurrence and development of colorectal cancer is closely related to the abnormal activation of Wnt signaling pathway. Abnormal expression of β-catenin in Wnt pathway is found both in the cytoplasm and nucleus of tumor cells. Different drugs can target the Wnt signaling pathway and its upstream and downstream related factors to inhibit or suppress the development of colorectal cancer. We review the components of Wnt signaling pathway, and the correlation between Wnt signaling pathway and colorectal cancer. Then, we summarize the current status of drug research targeting the Wnt signaling pathway in colorectal cancer. Finally, the challenges and prospects of these methods and drugs were briefly summarized.

In order to clarify material basis of effective parts of liangxue tongyu prescription, blood-heat and blood-stasis rat model induced by dry yeast was established. The changes of rectal temperature, blood viscosity and plasma viscosity were used to evaluate the cooling-blood and activating-blood effects of liangxue tongyu prescription and its parts. Compared with the model group, the extract from liangxue tongyu prescription, its volatile oil and n-butanol part could significantly reduce rectal temperature (P<0.01), and also reduce blood viscosity and plasma viscosity to various degrees (P<0.01 or P<0.05). So volatile oil and n-butanol part were primarily identified as effective parts of liangxue tongyu prescription. By using GC-MS with normalization method of area to analyze volatile oil of liangxue tongyu prescription, 70 compounds were identified, accounting for about 92.54%, mainly as β-asarone, paeonol, α-asarone and shyobunone. 42 compounds such as peony glycosides, tannins, and iridoid glycosides were identified by HPLC-MS techniques and standard comparison. The study determined the effective parts of liangxue tongyu prescription and clarified the chemical composition providing the foundation for further studies on material basis of liangxue tongyu prescription.
