ObjectiveTo observe the effect ofTong Du acupuncture-moxibustion, conventional acupuncture, and medication on the bone marrow stem cells (BMSCs) mobilization markers CD34+and CD133+, neurological deficit score in patients with ischemic stroke.Method Totally 120 eligible subjects with ischemic stroke were randomized into aTong Du acupuncture-moxibustion group (group A), a conventional acupuncture group (group B), and a medication group (group C), 40 in each group. In addition to the conventional medication given to all three groups, patients in group A also received moxibustion at Baihui (GV20), bloodletting at Dazhui (GV14), and acupuncture at Fengchi (GB20), Quchi (LI11), Hegu (LI4), Zusanli (ST36), and Sanyinjiao (SP6); patients in group B also received acupuncture at Fengchi, Quchi, Hegu, Zusanli, and Sanyinjiao; group C received patent Chinese medicine Tong Xin Luo capsules. The intervention lasted 14 d in all three groups. The CD34+and CD133+and neurological deficit score were evaluated and compared before and after intervention.Result The three treatment methods all significantly increased the level of CD34 + and CD133+in peripheral blood (P<0.05,P<0.01); the intergroup comparisons showed significant differences among the three groups (P<0.05), and the level in group A was significantly different from that in group B and C (P<0.05), while there was no significant difference between group B and C (P>0.05); the three treatment methods all improved the neurological deficit score to various extent, and the result in group A was significantly different from that in group B and C (P<0.05,P<0.01), and there was also a significant difference between group B and C (P<0.05).ConclusionsTong Du acupuncture-moxibustion, conventional acupuncture, and medication can influence the BMSCs and neurological deficit to different extent; the effect ofTong Du acupuncture-moxibustion on the BMSCs and neurological deficit is more significant than that of the conventional acupuncture and medication, suggesting thatTong Du acupuncture-moxibustion method should have advantage in treating cerebral infarction.

Objective:To study the interaction between cisplatin and bovine serum albumin ( BSA) under the simulated human physiological condition. Methods:The interaction mechanism of BSA and cisplatin was investigated by fluorescent spectrometry; the binding constant, binding site and interaction force were studied, and the interaction effects on the conformation change of BSA were investigated as well. Results:The results of fluorescent spectrometry showed that a ground state complex was formed between cisplatin and BSA, and the mechanism of fluorescence quenching was static quenching. The binding parameters of cisplatin and BSA were as follows:the binding constant was 1. 36 × 104 L·mol-1 , the binding site was 0. 991, and the interaction was mainly driven by hydrogen bonds and Van Der Waals forces. The results of synchronous fluorescent spectrometry demonstrated that the interaction influenced the micro-environments of amide acid residues. Conclusion:Cisplatin can interact with BSA and change the conformation of BSA.
