OBJECTIVETo discuss arthroscopic technique of single Kirschner wire and suture avoiding epiphyseal line fixation for tibial intercondylar eminence fracture and its clinical results.
METHODSFrom May 2008 to December 2012, 21 patients (13 males, 8 females, ranging in age from 6 to 14 years old) with tibial intercondylar eminence fracture were treated arthroscopically with single Kirschner wire and suture avoiding epiphyseal line fixation technique. According to Meyers and McKeever classification, 7 patients were type II, 10 patients were type III, and 4 patients were type IV. Active rehabilitation began at one week after operation. The patients were followed up for 10 to 30 months. X-ray films were taken to evaluate fracture healing at 1, 3, 6 months after operation; range of motion, the anterior drawer test, the lachman test and the Lysholm knee score were used to evaluate clinical effects.

Rutaecarpine (Rut) is a type of indole quinazoline alkaloid exracted from Ruticarpum. Studies showed that Rut has a wide range of pharmacological effects, such as anti-hypertension, anticancer, anti-inflammation, anti-thrombus formation. Currently, many scholars are committed to developing it into a new antihypertensive and anti-inflammatory drug with all new mechanisms. But studies found that Rut is a highly fat-soluble drug with low water and oil solubility. Its high insolubility is the main obstacle in its oral absorption and application, which greatly reduced its bioavailability. Therefore, hydroxypropyl-beta-cyclodextrin (HP-beta-CD) was used as the inclusion material to prepare Rut-HP-beta-CD inclusion complex in this experiment, in order to increase its water solubility and bioavailability. In this experiment, the inclusion complex was prepared by the stirring-freeze-dry method. The preparation process was optimized by the orthogonal test, with the inclusion rate as the index, and molar ratio between host and guest molecules, inclusion temperature, time and stirring speed as the impacting factors. Moreover, the inclusion complex was verified by detecting the apparent solubility, thin layer chromatography, microscopic identification, melting point detection and dissolution study. The results showed that under the conditions of the molar ratio between Rut and HP-beta-CD of 1: 1, temperature at 60 degrees C, inclusion time of 4h and stirring speed at 600 r x min(-1), the inclusion rate of Rut-HP-beta-CD reached 91.04%. Therefore, the preparation process of Rut-HP-beta-CD inclusion under the optimum conditions is simple and feasible, with a highest inclusion rate and reproducibility, and could significantly improve Rut's solubility and bioavailability, and provide a reliable experimental basis for its clinical application.

Objective To investigate the relationship between rapists and related allele genes based on the analysis of 15 short tandem repeats (STRs) loci genetic polymorphism. Methods The method of Genome-wide scan was being used. Buccal swab samples of 129 rapists and 156 random populations were collected and PCR compound amplification was carried out with the aid of AmpFISTR Identifiler system. Then the products were subjected to electrophoresis and gene detection with AB13100 type gene analysis system so as to calculate and compare the alleles of 15 STRs gene frequency in the two groups. Results All the 15 STRs loci allele gene frequency in rapists and random population was found to coincide with Hardy-Weinberg law(P>0. 05). Allele 28 of D21S11 (rapists: 1.55% ,control group:5. 13%) ,allele22 of FGA(rapists:24.03% ,control group:16.99%),allele23 of FGA(rapists: 17.05% ,control group:26.28%) ,allele 10 of TH01(rapists:1.16% ,control group:4.17%) ,allele 8 of TPOX(rapists:55.77% ,control group:63.77%),allele 12 of TPOX(rapists:4.26% ,control group: 1.28%) were different between the two groups (P< 0.05) .while it is no differ significantly in other STRs loci allele gene(P >0.05). Conclusion Allele 28 of D21 S11,allele 22 and 23 of FGA, allele 10 of TH01, allele 8 and 12 of TPOX may be associated with the violent crime of rape. It is suggested that there are existing sensitive or resistance genes about the violent crime of rape in chromosome 2,4,11,21.
