Central nervous system （CNS） is a sophisticated system subject to complex regulation， which dominates the high-level neural activities of the human body. Due to its complex physiological structure and refined regulatory mechanism covering a variety of diseases， CNS is the place where many chronic， refractory and rare diseases occur. Nerve cell is the basic unit of CNS， and its dysfunction and death is the root cause of CNS diseases. Ferroptosis is a new form of programmed cell death proposed in recent years， and has been proved to be closely related to the production and development of multiple CNS diseases. Traditional Chinese medicine （TCM）， including Chinese herbs， acupuncture and moxibustion， and massage， has shown unique advantages in the treatment of CNS diseases for a long time. A large number of studies have demonstrated that TCM participates in the regulation of CNS diseases via regulating ferroptosis and shows a good research prospect. This paper summarized the characteristics of ferroptosis and discussed the association between ferroptosis and CNS diseases in pathological mechanism. We also reviewed the regulation of various CNS diseases by different TCM interventions through ferroptosis， providing references for TCM to participate in the treatment of CNS diseases properly in the future.

Objective:To compare the adsorption and desorption properties of different anion exchange resins for total ginsenosides， clarify their adsorption/desorption mechanism， and establish a simple protocol for the purification of total ginsenosides. Method:The adsorption and desorption properties of five different resins （D301， D315， D312， D330， D201） on total ginsenosides were evaluated with specific adsorption capacity， specific desorption capacity， desorption rate and recovery rate as indices. The adsorption kinetics and thermodynamics of the selected resin and D101 macroporous resin were investigated by pseudo-first-order and pseudo-second-order kinetic models， as well as Langmuir and Freundlich isothermal adsorption models， and the differences of adsorption mechanism between anion exchange resin and conventional macroporous resin were elucidated. The dynamic adsorption and desorption experiments were used to determine the optimum chromatographic parameters for anion exchange resin. After verifying the purification process of total ginsenosides， nine individual ginsenosides were qualitatively and quantitatively analyzed by liquid chromatography-mass spectrometry （LC-MS）. Result:D301 anion exchange resin was obviously superior to the other four kinds of anion exchange resin， the optimum parameters were set as follows：pH 8 of loading solution， loading volume of 2 BV， loading speed of 4 BV·h^-1， eluted with 3 BV of water and 20% ethanol for the impurities， eluted with 8 BV of 80% ethanol with elution speed of 4 BV·h^-1. After purified by D301 resin， the enrichment coefficients of 9 monomer ginsenosides were simultaneously increased to different degrees， the overall enrichment coefficient was up to 5.3， the recovery rate for the total amount of these ginsenosides was calculated to be 80.9%， and the purity of total ginsenosides in Ginseng Radix et Rhizoma extract increased from 17.07% to 91.19%. Conclusion:D301 anion exchange resin is suitable for rapid and practical purification of total ginsenosides， hence allowing for the enrichment of high-purity total ginsenosides from Ginseng Radix et Rhizoma via one-dimensional column chromatography.

OBJECTIVETo summarize the acupoints for mental diseases in(GB/T30233-2013) so as to provide theoretical evidence for acupoint compatibility and acupuncture-moxibustion prescription.

METHODSThe acupoints for mental diseases inwere artificially retrieved,and then their frequencies,meridians and locations were analyzed.

RESULTSEighty acupoints were collected totally. Shenmen (HT 7) was with the highest frequency,and Baihui (GV 20) was followed. The frequently-used meridians in turn were governor vessel (GV),bladder meridian of foot-,small intestine meridian of hand-and stomach meridian of foot-,etc.,among which GV showed the highest number with 17 (21.25%) acupoints. As for the positions of analogical function acupoints,they in turn were head and face,upper limbs,lower lumbs,back and waist,chest and abdomen,with 30 percent acupoints locating at head and face.

CONCLUSIONSAnalogical acupoints for mental diseases are focused at head and face,and they are mainly along GV. The treatment is based on syndrome differentiation.

ObjectiveTo investigate the mechanism of modified Shenhong Tongluo prescription on cell apoptosis in rats with myocardial ischemia-reperfusion injury （MIRI）. MethodSixty Sprague-Dawley （SD） rats were randomly divided into a blank group， a model group， low-， medium-， and high-dose groups of modified Shenhong Tongluo prescription， and a simvastatin group. Except for the blank group， a rat model of MIRI was prepared by ligating the left anterior descending coronary artery. Starting from the first day after successful modeling， the blank group （1.0 mL·kg^-1 physiological saline）， model group （1.0 mL·kg^-1 physiological saline）， low-， medium-， and high-dose groups of modified Shenhong Tongluo prescription （1.031， 2.063， and 4.126 g·kg^-1 Shenhong Tongluo prescriptiona standard concentrate）， and simvastatin group （0.71 mg·kg^-1 simvastatin） were orally administered once daily for 2 weeks. Hematoxylin-eosin （HE） staining was used to observe the pathological changes of cardiomyocytes. Enzyme-linked immunosorbent assay （ELISA） was used to detect the levels of serum creatine kinase isoenzyme （CK-MB）， interleukin-6 （IL-6）， and tumor necrosis factor-α （TNF-α）. TdT-mediated dUTP nick-end labeling（TUNEL） staining was used to detect the apoptosis rate of rat cardiomyocytes. Western blot was used to detect the expression levels of apoptosis-related proteins B-cell lymphoma-2 （Bcl-2）， Bcl-2-associated X protein （Bax）， and caspase-3. ResultCompared with the blank group， in the model group， HE staining showed disturbed arrangement of cardiomyocytes， incomplete fibers， focal necrosis of cardiomyocytes， and inflammatory cell infiltration； serum CK-MB， IL-6， and TNF-α levels were significantly increased （P<0.05）； apoptosis rate of cardiomyocytes was significantly increased （P<0.01）， with significantly increased expression levels of Bax and Caspase-3 proteins， and significantly decreased Bcl-2 expression （P<0.05）. Compared with the model group， the low-， medium-， and high-dose groups of modified Shenhong Tongluo prescription significantly reduced CK-MB， IL-6， and TNF-α levels （P<0.05）， significantly downregulated cardiomyocyte apoptosis rate （P<0.05）， significantly decreased Bax and Caspase-3 proteins， and significantly increased Bcl-2 expression levels （P<0.01）. In the modified Shenhong Tongluo prescription groups， the expression levels of Bax and Caspase-3 proteins significantly decreased with increasing dosage， while the expression level of Bcl-2 significantly increased with increasing dosage of modified Shenhong Tongluo prescription （P<0.05）. ConclusionShenhong Tongluo prescription can alleviate myocardial tissue pathological damage and reduce myocardial cell apoptosis， possibly by inhibiting Caspase-3 and Bax expression and promoting Bcl-2 expression.

The objective was to evaluate the preventive and therapeutic effects of the collagen hydrolysate extracted from Sika deer velvet (CSDV) on osteoporosis rats induced by retinoicacid. Histomorphometric indices and serum biochemical parameters were measured in osteoporosis rats treated with/without antler collagen and in sham-operated rats. Our results were as follows: compared with the osteoporosis group, significant elevation in the levels of bone mineral density (BMD), Ca, P and static histomorphometric indexes and biomechanical properties, but reduction in the level of serum alkaline phosphatase (ALP) were observed in antler collagen-treated groups. However, the above function with the collagenase solution velvet material varied with the different doses. In conclusion, the extracted collagen is found to play a role in the prevention and treatment of osteoporosis rats by retinoic acid.
