Stroke is a common cerebrovascular disease， characterized by high incidence， mortality and disability rate. Neuronal cells， the basic unit of the central nervous system， can be injured to varying degrees when stroke occurs. Neuronal cell injury after stroke is also the key cause leading to neurological dysfunction， affecting the prognosis and quality of life of patients. Therefore， reducing the neuronal cell injury and delaying the process of cell death are effective to decrease the nerve function injury in stroke patients and improve their prognosis， thus lowering the death and disability rate of stroke. Ferroptosis is a new form of cell death that has been widely concerned in recent years. Several studies have confirmed that there is ferroptosis in neuronal cells after stroke. Since ferroptosis is an adjustable form， its intervention can help regulate the injury and death of neuronal cells. Studies have shown that inhibiting ferroptosis plays a role in protecting neuronal cells. Traditional Chinese medicine （TCM）， with the multi-channel and multi-target treatment advantages， has been widely used in the whole stroke and has achieved good clinical efficacy. It might be a new direction taking TCM regulation of ferroptosis as the entry point for stroke treatment in the future. This review revealed the mechanism of ferroptosis， discussed the research status of TCM in intervening in neuronal cell ferroptosis， and provided reference for further improving the efficacy of TCM in stroke.

In recent years, with the development of Chinese materia medica (CMM) industry, the problem of quality control method is not comprehensive. It becomes the most important factor to block the development of CMM. Many scholars look for some new methods, by which the quality of CMM could be assessed objectively and accurately. Since 1980s, the pattern recognition was introduced to the chemical field and was applied to CMM at the same time. And there were some CMM quality assessment methods based on the pattern recognition established so far. In this article, the latest research progress in the pattern recognition, basic principle, and technology, was introduced and the applications in principal component analysis, cluster analysis, discriminant analysis, grey correlation analysis, partial least squares, heuristic evolving latent projections and artificial neural networks of CMM quality assessment have been reviewed, so as to provide the reference for further studies and application in CMM.

ObjectiveTo explore the mechanism of Wutou Chishizhi Wan in regulating autophagy and phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/glycogen synthase kinase-3β （GSK-3β） signaling pathway in rats with myocardial ischemia-reperfusion injury （MIRI）. MethodSixty male SD rats were randomly assigned into the normal group （normal saline）， model group （normal saline）， positive control （trimetazidine， 5.4 mg·kg^-1） group， and low-， medium-， and high-dose （1.63， 4.9， 14.7 g·kg^-1， respectively） Wutou Chishizhi Wan groups， with 10 rats in each group. The rats in other groups except the normal group underwent left anterior descending coronary artery ligation for modeling. Electrocardiogram was employed to detect the ST-segment elevation to evaluate the modeling. Hematoxylin-eosin （HE） staining was performed to reveal the damage of myocardial tissue. The levels of aspartate aminotransferase （AST） and creatine kinase （CK） were determined by colorimetry， and those of cardiac troponin T （cTnT） and myoglobin （MYO） by enzyme-linked immunosorbent assay （ELISA）. Western blot was carried out to determine the protein levels of microtubule-associated proteins 1 light chain 3 （LC3）， autophagy-related gene Beclin-1， PI3K， Akt， GSK-3β， p-GSK-3β， and p-Akt. ResultCompared with the normal group， the modeling elevated the serum levels of AST， CK， cTnT， and MYO （P<0.01）， destroyed the arrangement of myocardial cells abd nucle， twisted and broken myocardial fibers， up-regulated the protein levels of LC3Ⅱ/Ⅰ and Beclin-1 （P<0.01）， and down-regulated the protein levels of PI3K， p-Akt， and p-GSK-3β （P<0.01）. Compared with the model group， trimetazidine and Wutou Chishizhi Wan （all the doses） lowered the levels of AST， CK， cTnT， and MYO in serum （P<0.01）， restored the arrangement of myocardial cells and muscle fibers， reduced necrosis， down-regulated the protein level of Beclin-1 （P<0.01）， and up-regulated the protein levels of PI3K， p-Akt， and p-GSK-3β （P<0.01）. Additionally， Wutou Chishizhi Wan （all the doses） down-regulated the protein level of LC3Ⅱ/Ⅰ （P<0.05， P<0.01）. Compared with those in the trimetazidine group， the serum AST level rose in the low-dose Wutou Chishizhi Wan group （P<0.05） and declined in the high-dose group （P<0.01）， and the protein level of Beclin-1 was down-regulated in the medium-dose group （P<0.01）. Additionally， the trimetazidine group had higher protein level of LC3Ⅱ/Ⅰ than medium- and high-dose Wutou Chishizhi Wan groups （P<0.05， P<0.01）， higher protein level of PI3K than low-， medium-， and high-dose groups （P<0.01）， lower protein level of p-Akt than low- and medium-dose groups （P<0.01）， and higher p-GSK-3β protein level than the medium-dose group （P<0.01）. ConclusionDifferent doses of Wutou Chishizhi Wan can ameliorate MIRI， and the high dose has the best effect. Wutou Chishizhi Wan can reduce the activity of myocardial injury markers AST， CK， cTnT， and MYO， and alleviate the pathological damage of myocardial tissue. It can down-regulate the protein levels of beclin-1， LC3Ⅱ/Ⅰ， and up-regulate those of PI3K， p-Akt， and p-GSK-3β. In summary， Wutou Chishizhi Wan may inhibit excessive autophagy and regulate the PI3K/Akt/GSK-3β signaling pathway to exert protective effect on MIRI rats.

Objective To compare the dosimetric differences of volumetric modulated arc therapy (VMAT) for preoperative radiotherapy of rectal cancer using 6MV X-ray flattening filter-free (FFF) and flattening filter (FF) modes.Methods FF-VMAT and FFF-VMAT plans were designed for 15 rectal cancer patients with preoperative radiotherapy by planning treatment system (Eclipse 10.0),respectively.Prescription dose of PTV was 50 Gy in 25 fractions.When the plans were normalized to 50 Gy to 95 ％ of PTV,the dose volume histogram (DVH),target and risk organ doses,conformity indexes (CI),homogeneity indexes (HI),low dose volume of normal tissue (B-P),monitor units (MU) and treatment time (TT) were compared between the two kinds of plans.Results FF-VMAT provided the lower Dmean,V105,HI (P ＜ 0.05),and higher CI (P ＜ 0.05) compared with FFF-VMAT.Small intestine (D5),Bladder (D5,Dmean V40,V50),L-femoral head (V40),R-femoral head (Dmean) were lower in FF-VMAT than those in FFF-VMAT (P ＜ 0.05).FF-VMAT had higher B-P (V5) compared with FFF-VMAT (P ＜ 0.05).FF-VMAT reduced the monitor units (MU) by 21％ (382±53 vs 483±26,P ＜ 0.05),as well as the treatment time (TT) in FF-VMAT was no significant difference compared with that in FFF-VMAT [(148±4) s vs (146±3) s,P ＞ 0.05)].Conclusions The qualities of FF-VMAT and FFF-VMAT plans were comparable and both clinically acceptable.When comparing two plans,FF-VMAT showed better target coverage and some of OARs sparing.The MUs of FFF-VMAT were higher than those of FF-VMAT,yet were not delivered within the same time.

Objective: To observe the transfer efficiency of protamine-DOTAP/Chol liposome-oligodeoxynuleotides complex to SKOV3 cells. Methods; Synthesized NF-?B decoy ODNs or scrambled ODNs labeled by FITC on the 5'ends was mixed with rationic DOTAP/cholesteral liposome and protamine, making the charge ratio of positive: negative 4.

The direct effect of NF-KB decoy ODNs transfer on the growth of SKOV3 cell line in vitro was measured by MTT method. Results: The efficiency of LPD transfer to SKOV3 cell line was 96. 41% , significantly higher than that of naked DNA transfer which was 12. 86%. The growth of SKOV3 cell line was not affected by 48h incubation after NF-KB decoy ODNs or scrambled ODNs transfection. Conclusion: LPD method is the one with high transfer efficiency not affected by NBS( newborn bovine serum) with possibility of use in vivo.
