OBJECTIVE:
To extract sperm DNA from mixed stain by the modified differential lysis method combined with silicon bead method and to evaluate its application value.
METHODS:
Fifty-two mixed stains containing female STR genotypes detected by differential lysis method were collected. The sperm DNA was extracted by the modified method combined with silicon bead method, then genotyped with the Identifiler Kit, and compared with the results of genotyping by the conventional differential lysis method as control.
RESULTS:
Of the 52 samples, 38 samples with sole male STR genotypes in all loci were detected. The detection rate of male STR genotypes was 98.08% through the modified method combined with silicon bead method.
CONCLUSION
The modified differential lysis method combined with silicon bead method can be used in extraction of sperm DNA from mixed stain.

The clinical characteristics of patients who presented in poor clinical grade due to ruptured middle cerebral artery aneurysms (MCAAs) associated with large sylvian hematomas (SylH) were analyzed and an ingenious designed prophylactic hinged craniectomy was introduced. Twenty-eight patients were graded into Hunt-Hess grades IV-V and emergency standard micro-neurosurgeries (aneurysm clipping, hematoma evacuation and prophylactic hinged craniectomy) were performed, and their clinical data were retrospectively analyzed. 46.43% of the patients reached encouraged favorable outcomes on discharge. The favorable outcome group and the poor outcome group significantly differed in terms of patients' anisocoria, Hunt-Hess grade before surgery, extent of the midline shift and time to the surgery after bleeding (P<0.05). There were no significant differences in age, sex, volume and location of the hematoma, size of aneurysm between the favorable and poor groups (P>0.05). However, ingenious designed prophylactic hinged craniectomy efficiently reduced the patients' intracranial pressure (ICP) after surgery. It was suggested that preoperative conditions such as Hunt-Hess grading, extent of the midline shift and the occurrence of cerebral hernia affect the prognosis of patients, but time to the surgery after bleeding and prophylactic hinged craniectomy are of significant importance for optimizing the prognosis of MCAA patients presenting with large SylH.

The technique introduced in this paper is applied in the endocardial catheter operation, which describes the 3D heart model reconstruction before the operation for the endocardial navigation. After a series of CT images of the thorax are processed, an accurate 3D endocardial model can be reconstructed. At first, the series of 2D CT images are preprocessed for denoising and the enhancement,then they are constructed as the volume data. After the region growing segmentation in the 3D volume data according to the grey value of the voxel in the heart cavity, the heart surface rendering is got and the 3D model of endocardial cavity is reconstructed.

Objective To compare the therapeutic effects and safety of monopolar and bipolar radiofrequency (RF) ablation used during cardiac surgery to treat atrial fibrillation.
Methods We retrospectively studied a total of 81 patients with chronic atrial fibrillation who underwent open cardiac surgery with concomitant RF ablation between January 2007 and March 2011. Fifty-eight patients received bipolar RF ablation and 23 received monopolar RF ablation, respectively. The sinus rhythm restoration rate, the procedural duration, the frequency of severe perioperative complications, and mortality were compared between the two groups.
Results The sinus rhythm restoration rate did not differ significantly between the two groups after follow-up of 15.1 ± 12.6 months (P=0.199). The frequencies of severe perioperative complications and mortality were also similar in the two groups. The total procedural time using bipolar RF ablation was significantly shorter than that using monopolar ablation (19.7±4.6 minutes vs. 28.1±8.5 minutes, P<0.001).
Conclusions Both monopolar and bipolar RF ablation are safe and effective in treating chronic atrial fibrillation patients during open cardiac surgery, but bipolar RF ablation is more convenient in practice.

OBJECTIVETo measure the stability of Evans procedure and Chrisman-Snook technique in the treatment of II degree lateral collateral ligament of ankle joint, and provide basis for treatment and prognosis.
METHODSFrom July 2008 to June 2009,18 frozen corpes were collected, including 10 males and 8 females, with an average age of fresh 39.3 +/- 11.2 years. The frozen corpes were randomly divided into three group, including normal controls(group A), Evans procedure (group B) and Chrisman-Snook technique ( group C), 6 specimens in each group. Anterior talofibular ligament and calcaneofibular ligament were cut off to cause II degree lateral collateral ligament in group B and C. Evans procedure or Chrisman-Snook technique were applied to restore lateral collateral ligament, and measure biomechnics. The displacement of tibiotalar joint and subtalar joint were observed.
RESULTS(1) The lateral stress results of tibiotalar joint showed the displacement by Evans procedure (group B) was greater than other groups (P < 0.0001). There were no significant differences between group A and C (P > 0.05). (2) The lateral stress results of subtalar joint showed the displacement by Evans procedure (group B) was greater than other groups (P< 0.0001). There were no significant differences between group A and C (P > 0.05).
CONCLUSIONAnkle instability is caused by ankle joint lateral collateral ligament injury. Chrisman-Snook technique is better than Evans procedure in stability on the early stage of ankle joint restoration, and conform to principle of biomechanics.

Chinese medicinal formulae (CMF) were usually used in the clinics of traditional Chinese medicines (TCM), which were critical for modernization of Chinese medicine to shed light on the interaction between CMF and biological organisms. However, correlation between system and part, macroscopic actions and microcosmic mechanism, ADME process and pharmacologic actions were usually neglected. The put-forward of integrative pharmacology provided a feasible approach to solve the problem of the fragmentation of TCM. For the past years, we applied the strategy of integrative pharmacology to study Yuanhu Zhitong prescription( YZP) systematically, and established two modes, chemical fingerprints-metabolism fingerprints-network targets and intestinal absorption-activity evaluation-data mining, to establish the interaction rule between the chemical composition and biological activity from multiple levels, such as the calculation and in vitro/vivo, which provided proof for the quality control, pharmacodynamic material basis and pharmacological action of YZP. In this paper, we summarized the related progresses of the research of YZP.

To apply chitooligosaccharide in the preparation of baicalin compound, in order to increase the drug dissolution in vitro, and investigate the basic property of the compound. Baicalin-chitooligosaccharide compound was prepared by using the solvent method. The structure and physicochemical properties of compound were analyzed by using differential scanning calorimetry (DSC), scanning electron microscopy (SEM), X-ray powder diffraction (XRD) and infrared vibrational spectrum (IR), and its dissolution behavior was also investigated. The results showed that the compound prepared at baicalin-chitooligosaccharide molar ratio of 1 : 1 could significantly improve the dissolution of baicalin. The results of DSC and XRD analysis suggested that baicalin may exist in an amorphous state. IR results indicated the interaction between baicalin and chitooligosaccharide. The baicalin-chitooligosaccharide compound could significantly improve dissolution in vitro of drug.
