AIM: To define the indications of C2 pedicle lag screw or C2 pedicle screw associated with C3 lateral mass screw to treat Hangman fracture, and evaluate the clinical applications. METHODS: Thirty-four patients with Hangman fracture were selected from Changzheng Hospital between February 2000 and December 2004, including 10 patients of type Ⅰ, 12 patients of type Ⅱ, and 8 patients of type Ⅱa, 4 patients of type Ⅲ. Levine-Edwards classification and graded: 2 patients of grade C spinal injury, 12 patients of grade Ds and 20 patients of grade E according to Frankel scale. Patients with typeⅠHangman's fracture were fixed by C2 pedicle lag screw, and patients with typeⅡ, Ⅱa and Ⅲ Hangman fracture were fixed by C2 pedicle screw associate C3 lateral mass screw. Postoperative neurofunctional recovery and fracture healing were studied. RESULTS: A total of 34 subjects were involved in the analysis of results. ① Frankle classification of postoperative neurofunctional recovery: There were 2 cases of grade C, 1 case recovered to grade E, and one case recovered to grade D. There were 12 cases of grade D, including 11 cases of recovered to grade E and one without change. ② In 3-6 months follow-up, X-ray of anterior-posterior and lateral position showed that all fractures healed without loose screw, vertebra artery injury or other complications. CONCLUSION: C2 pedicle lag-screw, C2 pedicle screw associated with C3 lateral mass screw are safe, effective in the treatment of Hangman fracture, which can to retain the function of upper cervical spine as great as possible.

Percutaneous coronary intervention(PCI) has become one of the most important therapeutic methods for atherosclerotic heart disease(AHD),but the following complications such as stent thrombosis and restenosis af- fected its long-term efficacy.Platelet activation was a key component of thrombosis of during perioperative period PCI.As one of the most effective antiplatelet drugs,clo- pidogrel has been established its important role in preven- ting thrombosis during perioperative period of PCI.After several large-scale clinical trials in recent years.

The COI gene as DNA barcode was used to identify the Manis pentadactyla and its adulterants in order to provide a scientific basis for the molecular identification of M. pentadactyla. Genomic DNA was extracted from experimental samples using the DNA extraction kit. The COI genes were amplified using polymerase chain reaction (PCR) and sequenced bi-directionally. Obtained sequences were assembled using the CodonCode Aligner. The neighbor-joining (NJ) tree was constructed by MEGA 6.0. The results indicated that COI sequences were successfully amplified and NJ trees results indicated that M. pentadactyla and its adulterants can be easily identification. Therefore, the COI gene is an efficient barcode for identification of M. pentadactyla and its adulterants,which will provide a new technique for the market supervision.

Objective: This study aimed to distinguish Serpentis Periostracum from its adulterants, which will provide the basis for its safe application. Methods: Here, COI sequences of 68 samples from 13 species were PCR amplified and sequenced. Furthermore, the DNA Barcoding Gap and phylogenetic cluster analysis were carried out. Results:The results exhibited that the COI sequences of all the three origin animals of Serpentis Periostracum have DNA Barcoding Gap. For phylogenetic cluster analysis, all the three origin animals showed monophyletic and every species can be discriminated clearly. Conclusion: COI is an effective DNA barcode for the identification of Serpen-tis Periostracum.

The content of the asarone submicro emulsion injection was determind by HPLC method, and thereby a quality evaluation method was established based on indexes of pH value, particle size, peroxide value, methoxy aniline values, free fatty acid, lysophosphatidylcholine, visible foreign substances, insoluble particle, sterility, bacterial endotoxin and impurities, etc. The results showed that the injection exhibited uniform physical appearance and all the products were in milkwhite liquid. The content of the three batches products were respectively 102.9%, 100.8%, 97.70% of the labeled amount, with mean particle size of 210-250 nm, and other indexes all met with the standards. The reserved samples showed no obvious change in terms of detection indexes and indicated good stability after the accelerated stability test and long-term stability for 12 months. The quality evaluation method established in this study could be applied to quality control and stability investigation of asarone submicron emulsion injection, which laid a basis for further clinical research and application.
