Chinese traditional patent medicine for promoting blood circulation and removing blood stasis(PBCRBS) originated from traditional Chinese medicine theory and had approved efficacy and safety standards. However, its compatibility regularity and anti-thrombotic mechanism is not clear. To analyze the compatibility regularity and anti-thrombotic mechanism of Chinese traditional patent medicine for PBCRBS, a statistical and bioinformatics analysis was carried out using traditional Chinese medicine inheritance support system (TICMISS, V2.0) and ingenuity pathway analysis (IPA). The compatibility regularity analysis shows that the most commonly used herb combinations are Danshen (Salvia miltiorrhiza Bge.), Chuanxiong (Ligusticum chuanxiong Hort.) and Honghua (Carthamustinctorius L.). The anti-thrombotic mechanism analysis reveals that 25 ingredients have an effect on 29 thrombosis related molecules which 23 molecules are related to inflammation response. Furthermore, there are 5 inflammation molecules (NOS2, PTGS2, IL6, TNF, IL1β) served as major targets. At the same time, Danshen, Chuangxiong and Honghua mainly used as sovereign herb or minister herb in the application of cardiovascular and cerebrovascular diseases. Therefore, Chinese traditional patent medicine for PBCRBS probably has an effect on anti-thrombotic activity through inhibiting the inflammatory response. In summary, the most commonly used herb combinations of Chinese traditional patent medicine for PBCRBS are Danshen, Chuanxiong and Honghua. Inhibiting inflammatory response, especially inflammation related molecules (NOS2, PTGS2, IL6, TNF and IL1β), is probably a new starting point to clarify the anti-thrombotic mechanism of Chinese patent medicine for PBCRBS.

Objective Toinvestigatetheoperativeeffectandsafetyofendovascularstentingfor thetreatmentofsymptomaticvertebralarteryostialstenosis.Methods Fortypatientswithsymptomatic vertebral artery ostial stenosis and stenosis rate ≥70% were admitted to the Department of Neurology, China-Japan Friendship Hospital from November 2010 to January 2013 were enrolled retrospectively. All patients received endovascular stenting therapy,15 of them were implanted bare metal stents,and 25 were implanted drug eluting stents. The technical successful rate of operation,perioperation complications,and symptom remission rate of the patients were analyzed. At the same time,stroke and death incident as well as the related ischemic symptoms of the stent vascular feeding area in the follow-up period (13 to 36 months)wereobservedandtherestenosisratewasdocumented.Results Atotalof42stentswereimplanted in 40 patients,and the technical success rate was 100. 0%. The preoperative stenosis rate of vertebral artery ostial stenosis was 75% to 99%(mean 85 ± 7%);the postoperative stenosis rate was 0% to 20%(mean 6 ± 4%). There was no perioperative complication. The clinical symptoms of 19 patients disappeared completely,16 were improved significantly within the follow-up period,and the symptom remission rate was 87. 5%. No stent vascular feeding area related stroke and death occurred. Four patients had transient ischemic attack in posterior circulation,13 had restenosis after procedure (10 of them with bare mental stents and 3 with drug eluting stents). There was significant difference in restenosis rate between the bare mental stents andthedrugelutingstents(10/15vs3/25,P=0.001).Conclusion Endovascularstentingforthe treatment of the severe symptomatic vertebral artery ostial stenosis is a safe and efficient method. Although its restenosis rate is high,but it can improve the symptom of posterior circulation ischemia effectively.

Objective In the context of worldwide shortage of amytal,explore the intracarotidpropofol test for lateralizing language area and assessing hemispheric memory function.Methods Fourteen patients with refractory partial epilepsy who were candidates for surgical intervention were included in the study.With guide under a digital subtraction angiography,propofol was injected in bilateral intracarotidsequentially.Muscle power deceasing to level 0 at the contralateral limb and eyes gazing to contralateral side were used as the mark of hemispheric anesthesia completely.The immediate language alterations were recorded.To evaluate the bilateral language and memory functions,the visual and auditory memory tasks were performed sequentially once patient could concentrate his attention ; and after limb muscle power recovering to normal level,patients were required to perform a free recall test.Any abnormal responses were recorded.Results Language dominant hemisphere was determined in 14 patients.Nine patients were confirmed as left language dominance,2 patients were right language dominance.The remained 3 patients were considered as bilateral language dominance.Meanwhile,the hemispheric memory function was able be evaluated in 13 patients.More than 67％ memory function was sustained in hemisphere contralateral to mesial temporal lesions.Transient responses including eye pain,facial muscle spasms,laughers and involuntary movements were observed.Conclusion Hemispheric language and memory functions can be assessed with direct intracarotidpropofol injection,and propofol could be an alternative drug to amobarbital used in the Wada test.

Objective: To investigate the effects of human adipose-derived mesenchymal stem cells (ADSCs) and platelet-rich plasma (PRP) on healing of wounds with full-thickness skin defects in mice. Methods: ADSCs were isolated from the lumbar and abdominal fat donated voluntarily by a healthy woman undergoing liposuction in the Department of Plastic Surgery of Guangzhou General Hospital of Guangzhou Military Area Command, and the cells were cultured and identified. ADSCs of the second passage were used in the following experiments. The venous blood of the volunteer was taken, and PRP was obtained by secondary centrifugation. Thirty-six C57BL/6 mice were divided into simple injury group (n=12), simple ADSCs treatment group (n=12), and ADSCs+ PRP treatment group (n=12) according to the random number table. Each mouse was inflicted with a 1 cm×1 cm wound with full-thickness skin defect on the back. Immediately after injury, the wounds of mice in simple injury group were subcutaneously injected with 1 mL normal saline, the wounds of mice in simple ADSCs treatment group were subcutaneously injected with 1 mL phosphate buffer solution-blended ADSCs suspension (with concentration of 5×10⁵ /mL, the same below), and the wounds of mice in ADSCs+ PRP treatment group were subcutaneously injected with 1 mL mixture of PRP and ADSCs (1∶2 volume ratio). Three mice in each group were taken on post injury day (PID) 3, 5, 7, and 14 to observe the gross condition of wound, and the wound healing rate was calculated. On PID 3, 5, and 7, the non-healing wound tissue and 0.5 cm normal skin tissue around the wound margin were taken after gross observation. The inflammation, re-epithelialization, and angiogenesis of tissue were observed by hematoxylin and eosin staining, and the re-epithelialization rate was calculated. The collagen synthesis of tissue was observed by masson staining. Immunohistochemistry was used to observe the expression of macrophages of tissue samples collected on PID 3 and 5. Data were processed with analysis of variance of factorial design and Least-Significant Difference test. Results: (1) On PID 3, the wounds of mice in ADSCs+ PRP treatment group were with granulation tissue regeneration, redness, and swelling, and the wounds of mice in the other two groups were ruddy and with effusion. On PID 5, the wounds of mice in ADSCs+ PRP treatment group had less redness and swelling, which were dry with obvious scab, and wounds of mice in the other two groups were obviously red and swollen. On PID 7, scab formed basically on wounds of mice in the three groups. On PID 14, the wounds of mice in the three groups basically healed, and their crusts were off. On PID 3, 5, 7, and 14, the wound healing rates of mice in ADSCs+ PRP treatment group were obviously higher than those of the other two groups (P<0.05 or P<0.01). On PID 5 and 7, the wound healing rates of mice in simple ADSCs treatment group were obviously higher than those of simple injury group (P<0.01). (2) On PID 3, granulation tissue regeneration of wounds in ADSCs+ PRP treatment group was more than that in the other two groups. On PID 5, inflammatory reaction of wounds of mice was mild in ADSCs+ PRP treatment group, which was severe in the other two groups. On PID 7, the re-epithelialization process of wounds of mice was almost completed in ADSCs+ PRP treatment group, and the number of new vessels was more in ADSCs+ PRP treatment group than in the other two groups. The migration distance of regenerated epithelia around the wound edge in simple injury group and simple ADSCs treatment group was short. On PID 3, 5, and 7, the re-epithelialization rates of wounds of mice in ADSCs+ PRP treatment group were (37.6±4.5)%, (59.1±1.3)%, and (89.2±4.3)%, respectively, significantly higher than (25.7±1.5)%, (34.5±4.4)%, and (50.8±2.7)% in simple injury group and (29.1±0.8)%, (42.6±2.9)%, and (72.9±3.0)% in simple ADSCs treatment group (P<0.01). On PID 5 and 7, the re-epithelialization rates of wounds of mice in simple ADSCs treatment group were significantly higher than those in simple injury group (P<0.05 or P<0.01). (3) On PID 3 and 5, a quite large number of new collagen fibers appeared in granulation tissue of wounds of ADSCs+ PRP treatment group, while the collagen fibers in the other two groups were less. On PID 7, the granulation tissue of mice in ADSCs+ PRP treatment group decreased, and a large number of new collagen fibers appeared. The collagen fibers in wounds tissue of mice in simple ADSCs treatment group increased, while the collagen fibers deposited in wounds tissue of mice in simple injury group was still less. (4) On PID 3 and 5, the numbers of macrophages in wounds tissue of mice in simple ADSCs treatment group were 4.7±0.6 and 5.3±0.6 respectively, obviously lower than 6.3±0.6 and 7.7±0.6 in injury group (P<0.05 or P<0.01); the numbers of macrophages in wounds tissue of mice in ADSCs+ PRP treatment group were 3.0±1.1 and 2.7±0.5, significantly lower than those in the other two groups (P<0.05 or P<0.01). Conclusions Human PRP and ADSCs are involved in the early inflammation, metaphase of tissue proliferation, and re-epithelialization and shaping process of late stage of wounds with full-thickness skin defects in mice. The combination of ADSCs and PRP may be a comparatively good combination to improve the speed and quality of wound healing.
