@#Objective To study the effect of Tangeretin on non-small cell lung cancer (NSCLC) and the tumor stemness, and to find the molecular mechanism of its effect. Methods We used cell counting and cell cloning experiments to study the effect of Tangeretin on the proliferation of NSCLC cells in vitro. The effect of Tangeretin on the invasion of NSCLC cells was detected by transwell assay. We detected the effect of Tangeretin on the proliferation of NSCLC cells in vivo by nude mouse tumor-bearing experiment. The effect of Tangeretin on tumor stemness of NSCLC cells was detected by self-renew assay, and CD133 and Nanog protein expressions. The expressions of PI3K/AKT/mTOR signaling pathway-related proteins were detected by Western blotting (WB). Results Tangeretin had a good inhibitory effect on the proliferation of NSCLC cells in vivo and in vitro. Cell counting experiment, clonal formation experiment and nude mouse tumor-bearing experiment showed that Tangeretin could inhibit the proliferation activity, clonal formation ability, and tumor size of NSCLC cells in vivo. Self-renew experiments showed that Tangeretin could inhibit the self-renew ability of NSCLC cells. WB experiments showed that Tangeretin inhibited the expressions of tumor stemness markers CD133 and Nanog in NSCLC cells. Tangeretin could inhibit the activation of PI3K/AKT/mTOR signaling pathway-related proteins in NSCLC cells, and the activation of PI3K/AKT/mTOR signaling pathway could partially remit the inhibitory effect of Tangeretin on tumor stemness of NSCLC cells. Conclusion Tangeretin can inhibit the tumor stemness of NSCLC cells, which may be related to the regulation of PI3K/AKT/mTOR signaling pathway.

RESUMEN
The pharmacokinetics of traditional Chinese medicine is a subject that studies the dynamic changes of the absorption, distribution, metabolism and excretion of complex components of traditional Chinese medicine, which is an important method for elucidating the pharmacodynamic material basis, action characteristics, and compatibility mechanisms of traditional Chinese medicine. However, given on the fact that traditional Chinese medicine is a multi-dimensional and complex system with multiple components, multiple pathways, multiple targets, and an unclear pharmacodynamic material basis, the research on the pharmacokinetics of traditio-nal Chinese medicine has become a scientific and technological problem. Although the pharmacokinetics of traditional Chinese medicine has achieved remarkable development with the emergence of new theories, methods and technologies, there are still some problems in the application of the research direction of the pharmacokinetics of traditional Chinese medicine judging from the current application of the National Natural Science Foundation of China. Therefore, this article discussed the current research status on pharmacokinetics of traditional Chinese medicines by analyzing the projects funded by the National Natural Science Foundation of China in the past 5 years from 2016 to 2020, mainly including the application and funding analysis, main research contents of the projects in pharmacokinetics of traditional Chinese medicines. And the research hotspots, difficulties and deficiencies were focused in order to provide certain reference for researchers engaged in pharmacokinetics of traditional Chinese medicine.

BACKGROUND: Preliminary study found that polylactic acid composite material could accelerate the bone construction rate, and the underlying mechanism still needs to be studied further. OBJECTIVE: To investigate the effect of lactic acid at different concentrations on osteoclast differentiation of mononuclear cells in mice. METHODS: Mouse RAW264.7 cells were cultured in DMEM with 0 (control group), 5, 10 and 20 mmol/L lactic acid, respectively, under the induction of 50 µg/L RANKL for 5 days. The effect of lactic acid concentration on the cell proliferation rate was analyzed by cell counting kit-8 assay. Tartrate resistant acid phosphatase positive polykaryotic cells were stained and counted with tartrate resistant acid phosphatase staining kit. mRNA expression levels of acid phosphatase 5, nuclear factor of activated T-cells 1 and RANK were detected by RT-PCR. Protein expression levels of cathepsin K and nuclear factor of activated T-cells 1 were detected by western blot assay. RESULTS AND CONCLUSION: (1) 5 mmol/L lactic acid produced the highest proliferation rate of raw264.7 cells, whereas the 20 mmol/L lactic acid produced lowest cell proliferation rate. Compared with the control group, the proliferation rate of raw264.7 cells by 10 mmol/L lactic acid was insignificant. (2) Tartrate resistant acid phosphatase staining showed the highest positive rate and mRNA expression levels of acid phosphatase 5, nuclear factor of activated T-cells 1 and RANK under the condition of 10 mmol/L lactic acid. (3) With the increase of lactic acid concentration, the expression level of cathepsin K increased, while the expression level of nuclear factor of activated T-cells 1 was on a decline. (4) Under the current experimental conditions, with the increase of lactic acid concentration, the ability of lactic acid to promote the osteoclast differentiation of mouse RAW264.7 cells is firstly increased and then decreased, and 10 mmol/L lactic acid was the optimal concentration to promote the osteoclast differentiation of mouse RAW264.7 cells. Lactic acid can affect the osteoclastic differentiation of mouse raw264.7 cells by nuclear factor of activated T-cells 1 in nuclear factor-KB signaling pathway.

BACKGROUND: A large amount of literature has been published on the vertebral pedicle morphology at thoracolumbar segments in adults,but little is known about the morphology of pedicles in adolescents, especially in Asian populations. Adolescent spine disorders are increasing and there are few precise morphological studies. OBJECTIVE: To investigate the anatomy of lumbar vertebrae of adolescents aged 12-15 years in Inner Mongolia, provide detailed information for pedicle screw placement, determine the safe and appropriate screw size, and provide data reference for screw size design. METHODS: The normal chest and lumbar CT data of 65 adolescents aged 12-15 years in Inner Mongolia were collected and divided into two groups, 31 cases of 12-13 years old, and 34 cases of 14-15 years old. The raw data of the thoracic and lumbar vertebrae images scanned continuously were imported into Mimics 21.0 for analysis and measurement in DICOM format. Pedicle width, pedicle height, transverse diameter, longitudinal diameter, pedicle length, pedicle outer declination, pedicle maximum external angle, pedicle head inclination, and pedicle area were measured. RESULTS AND CONCLUSION: (1) The L1-L4 pedicle width in the two groups was less than pedicle height, and pedicle width and pedicle height at L5were similar. The pedicle width determined the screw diameter, which was larger in males than in females. (2) In 12-13 years old, the screw length at L1-L5 was between 40-45 mm. In 14-15 years old, the screw length was between 40-45 mm at L1-L4 , and 45-50 mm at L5 (3) The laws of the two groups were the same. The transverse diameter of spinal canal was significantly larger than longitudinal diameter of spinal canal (P<0.05), and there was no significant difference between men and women. (4) The transverse pedicle angle: In 12-13 years old L1-L2 had small change,L2-L5 gradually increased; in 14-15 years old, L1-L5 gradually increased; it is larger in males than in females in both groups. (5) Maximum transverse pedicle angle: The two groups had the same law. L1-L5 gradually increased, and decreased with age. There was no significant difference between left and right sides and sexes. There was significant difference among different ages (P<0.05). (6) The sagittal pedicle angle: The in 12-13 years old, 30-80; in 14-15 years old, 00-50. The value decreased with age, and there was significant difference between men and women in L3-L4 (P<0.05). (7) Pedicle area: The two groups had the same rules. L1-L5 gradually increased, and L4-L5 had a clear trend of change. (8) Analysis of pedicle parameters showed that the size of the screws in the lumbar vertebrae of normal adolescents was suitable for the clinician to grasp the anatomy of the lumbar spine and improve the accuracy of clinical operation.
