AIM: To evaluate the ability of spectral domain optic coherence tomography ( SD-OCT ) parameters to detect progressive structural damage in primary open angle glaucoma ( POAG) by contrasting with visual field. ·METHODS: Retrospectively we evaluated 48 subjects (48 eyes ) of POAG, followed up 14 to 62mo. The parameters of SD-OCT and visual field were obtained. The correlation between the change of visual field measurements and OCT measurements were analyzed. Visual field progression was defined as reproducible drop of at least 2dB of mean deviation (MD) from the baseline visit. ROC curve was made to evaluated the ability of OCT parameters in detect progression of POAG. ·RESULTS: The 25 eyes were classified in progression group and 23 eyes were in non-progression group. No significant correlation was seen between OCT parameters and visual field in non-progression group. In progression group, OCT parameters which were significantly correlated with MD reduce were rim volume ( r=-0. 5997, P=0. 0007), C/D vertical ratio (r=-0. 6309, P=0. 0003), RNFL(r= 0. 4201, P= 0. 0260), and GCC(r= 0. 7080,P<0. 01). ROC curves showed the GCC reflected the reduce of MD accurately (P=0. 013). ·CONCLUSION: Part parameters of SD-OCT can reflect the progression of POAG accurately and provided a new method to detect the damage of visual function of POAG.

The operation path, lymph node dissection and reconstruction of the alimentary tract are the three most technical difficulties of laparoscopy-assisted gastrectomy. The essential difference between laparoscopy-assisted gastrectomy and open gastrectomy is the operation path. Based on our clinical experience, we investigated reasonable paths for laparoscopyassisted gastrectomy. Patients were placed in a supine position with their legs apart, and the operator stood on the left side of the patient. Five trocars were placed in the abdominal wall in a curved line. The operation was carried out in the order of greater gastric curvature, the lower region of the pylorus and antrum,the upper region of the pancreas, omentum minus, cardia, and arcuate diaphragm. From May 2004 to April 2010, we successfully carried out 761 laparoscopy-assisted gastrectomies with satisfactory outcomes.

Objective To evaluate the clinical value and the early therapeutic efficacy of hysteromyomas treated with the radiofrequency ablation (RFA) by two-dimensional contrast-enhanced ultrasound(2D-CEUS) and three-dimensional contrast-enhanced ultrasound(3D-CEUS). Methods A total of 90 patients with 150 hysteromyomas were treated with RFA, including 138 intramural myomas and 12 submucous myomas (in which 5 had micr-pedicles). 2D-CEUS and 3D-CEUS were performed within one day before and after RFA treatment, respectively. The blood supply of focal zone(FZ) was observed by 2D-CEUS and 3D-CEUS. The volume of hysteromyomas and the coagulation necrosis range were measured by 3D-CEUS. The average necrotic rates of hysteromyoma were calculated. Results The 5 submucous myomas with micr-pedicles were removed completely after the RFA treatment. The 2D-CEUS appearances of other 145 hysteromyomas were diverse after the RFA treatment, in which 137 FZs had no contrast infusion,indicating complete ablation, 8 FZs appeared peripheral linear or small flaky enhancement, considering incomplete treatment. The 3D-CEUS performances were variant too, in which 132 FZs vascular network displayed as a "cavity", indicating complete tumor necrosis, the other 7 FZs appeared "branch shape" low enhancement and another 6 FZs showed nonuniform low enhancement, considering residual tumor tissue. The average necrotic rate of the 139 hysteromyomas was (97.1 ± 12. 9)% ,another 6 hysteromyomas was only (46. 4 ± 7. 0) %. Conclusions 3D-CEUS can display vascular structure and spatial relationship of the hysteromyomas, which can be used as the complement of 2D-CEUS. The combination of the two techniques can evaluate the earlier therapeutic efficacy of hysteromyomas by RFA more timely, intuitively and accurately.
