Objective: To establish and authenticate the chloasma mouse model with syndrome of liver-qi stagnation,and compare it with other existent models.Method: After the injection of progesterone,chronically constrained them and gave them partially ultraviolet radiation.Results: Multiple models of progesterone injection and ultraviolet radiation compounding with chronic constraint can heighten MDA,depress SOD,and increase melanocytes of skin.Meanwhile,the ethology of this model showed it's syndrome of liver-qi stagnation.Conclusion: The multiple factor chloasma mouse model of liver-qi stagnation syndrome has been built successfully.

Objective:To study the change rule of rats'pulse waves after kidney resection.Methods:To collect the pulse waves of femoral artery in each side of rats in Drugged state.Then do one-side kidney resection operation,after fully recover from it,collect the pulse waves again.To average the pulse waves in the same cycle length and then do the LSQ regression by 6 harmonics which are correspond with the cycle lengths,analyze the phase and the amplitude of vibration of fundamental wave and harmonics by statistical method.Results:The amplitude of vibration of the 3rd harmonics of pulse waves of femoral artery in the same side with operation and the amplitude of vibration of the 1st to 5th harmonics of pulse waves of femoral artery in the other side with operation has reinforced, the phase of the 1st and 2nd harmonics also have changed regularly.Conclusion:There're some regular changes in the pulse waves of rats after one-side kidney resection operation,which shows that the pulse waves of artery on the body surface can reflect the splanchnic changes.This research can offer some scientific foundation to the pulse-diagnosis in TCM.

【Objective】 To investigate the level of serum bone metabolism and biochemical markers and bone density of plasmapheresis donors, and to provide scientific basis for ensuring the health and safety of plasmapheresis donors in China. 【Methods】 A total of 437 plasmapheresis donors from Linwu plasmapheresis station in Hunan Province from July 1 to September 30, 2022 were recruited to determine the levels of total serum calcium, albumin, serum 25-hydroxyvitamin D (25OHD), serum type I procollagen N-terminal propeptide (P1NP), and collagen type 1 crosslinked carboxyl-terminal peptide (β-CTX). Dual-energy X-ray method was used to measure the bone density of the anteroposterior lumbar spine (L1-L4) and bilateral femoral neck bone density of plasmapheresis donors. Plasmapheresis donors were grouped according to the type of plasma donation (first-time and repeat plasmapheresis donors) and the total number of plasma donations to assess the differences in bone density and serum bone metabolism biochemical markers between groups. The dose-response relationship between the total number of plasmapheresis donations and biochemical indexes was analyzed by limiting cubic spline, and the influencing factors of different indexes were explored by multiple linear regression. 【Results】 A total of 437 plasmapheresis donors were included in this study, including 187 first-time plasmapheresis donors and 250 repeat plasmapheresis donors. There were no significant differences in bone density and prevalence of osteoporosis between first-time donors and repeat donors (P>0.05). There was also no significant difference in bone density levels between groups of total number of plasmapheresis donations. The levels of albumin and 25OHD decreased with the increase of the total number of plasma donations, while the serum P1NP level was positively correlated with the total number of plasma donations. The results of the restriction cubic spline showed that the total number of plasmapheresis donations had a nonlinear dose-response relationship with 25OH and P1NP (P<0.05). The results of multiple linear regression showed that the frequency of plasmapheresis donation was the influencing factor of 25OHD, and the total number of plasmapheresis donation was the influencing factor of P1NP. 【Conclusion】 Plasmapheresis donation does not affect the bone health of donors and increase the risk of osteoporosis due to the use of long-term anticoagulants, but it will increase the osteogenic activity of plasmapheresis donors. It is recommended that middle-aged and elderly plasmapheresis donors supplement vitamin D appropriately.
