Methods The vascular crisis of 132 digits of 98 cases were observed during intraoperative. The replantation was performed under different time and different conditions. The causes of vascular crisis, and propose effective prevention and management of vascular crisis were restrospective analysis. Results From March 2006 to June 2007, 35 amputated digits occurred vascular crisis during intraoperative, 19 amputated digits occurred during postoperative. After using warm physiological saline and injecting the papaverine partly, we proceed operations research with regard to the non-catabatic amputated digits. As result 58 digits survived, the achievement ratio was 89.2%. From July 2007 to March 2009, 10 amputated digits occurred vascular crisis during intraoperative,5 amputated digits occurred during postoperative. After non-surgical treatment, we performed operations research regard to the non-catabatic amputated digits. After blood supply recover, we imbed PCA pump into flex tendinous sheath to avoid the occurrence of vascular crisis postoperative. As result 66 digits survived, the achievement ratio was 98.5%. postoperative 9 cases out of fullow-up, 89 cases follow up ranged from 6 to 8 months. Recovery of the hand function was good. Conclusion Good and adequate anesthetic and an appropriate ambient temperature during operation are important factors to prevent occurrence of vascular crisis in digital replantation. Paying enough attention to these factors can effectively improve the survival rate of replantatian.

Objective To study the mechanisms of Liujing Toutong Tablets (LTT) in the treatment of migraine by network pharmacology. Methods Eighteen components of LTT absorbed into blood were selected as the objects, and targets of compounds were predicted according to the reverse pharmacophore matching method. The related pathways and correlation analysis were explored by the MAS 3.0 biomolecule function software and the Kyoto Encyclopedia and Genomes (KEGG) database. Finally, the network of compound-target-pathway-disease of LTT was constructed by Cytoscape software. Results Eighteen compounds interacted with 88 pathways through 72 targets, of which 36 protein targets and 22 pathways were associated with migraine. Conclusion LTT may play a role in expelling wind and dredging collaterals, promoting orifice and pain-relieving by intervening with the related pathways of inflammation, homeostasis of blood vessels, nervous centralis, immunity, and hormonal regulation.

Objective To investigate the clinical features of polypoidal choroidal vasculopathy. Methods The clinical manifestations and the findings of fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) of 7 eyes in 6 patients with polypoidal choroidal vasculopathy were analyzed retrospectively. Results The ophthalmoscopic examination of PCV in this series of patients revealed orange-red lesions mainly in macular region in early stage, and then hemorrhage, exudation, edema, serous and (or) hemorrhagic detachment of retinal pigment epithelium in affected portions in advanced stage, and retinal and choroidal atrophy in late stage. FFA discovered the vascular dilation at the border of the choroidal vascular network in 1 eye, dotted hyperfluorescence in 6 eyes, and patches of hyperfluorescence in late phase. ICGA disclosed a vascular branching network in choroid with polypoid pattern of the terminal path of the vessels of network in early phase in 5 eyes, and the typical dotted or clustered polypoidal hyperfluorescence in 7 eyes in late phase. Conclusion The characteristic findings of FFA and ICGA are very diagnostic for PCV.

Journal of Forensic Medicine 2014;30(6):452-455
OBJECTIVE:
To discuss blood collection tubes with different additives and their effects on the testing results of alcohol concentration in blood samples.
METHODS:
Blood samples from 10 volunteers were collected 2 hours after drinking with seven different types of disposable vacuum blood collection tubes, including ordinary tube without anticoagulant, coagulant tube, separating gel-coagulant tube, sodium citrate (1:4) tube, sodium citrate (1:9) tube, sodium citrate (9:1) tube and EDTA-K2 tube. The alcohol concentrations in these blood samples were analyzed by headspace gas chromatography.
RESULTS:
The concentration testing results of the same blood samples in different types of tubes were different from one to another. The sequence was as follows: separating gel-coagulant tube > coagulant tube > ordi- nary tube without anticoagulant > EDTA-K2 tube> sodium citrate (1:9) tube> sodium citrate (1:4) tube, whereas the results of the same blood sample in sodium citrate (1:9) tube and sodium citrate (9:1) tube showed no obvious difference.
CONCLUSION
It is better to collect a suspicious drunk driver's blood sam- ple using a disposable vacuum blood collection tube, with the EDTA-K2 tube being preferred.
