Objective To compare the treatment effect of internal fixation with retrograde interlocking intramedullary nails or condylar plates in the treatment of comminuted fracture of the femoral condyle. Methods 36 cases of comminuted fracture of femoral condyle admitted from 2000 to 2005 were treated with retrograde interlocking intramedullary nails (n=19) or condylar plates (n=17). Union time of fracture and the recovery of knee function were observed respectively. Results The average union time of fracture of the cases treated with retrograde interlocking intramedullary nails was 102 days, and the score of knee function was 84.59. Whereas in the cases treated with condylar plates the union time of fracture was 91.35 days, and the score of knee function was 91.10. Significant differences in both union time of fracture and knee function between the two therapeutic methods were observed (P

Study the infect of child anorexia granule on serum ghrelin and leptin of anorexia children and its clinical efficacy. Selected 81 cases of anorexia children aged 1-6 years old into treatment group (42 cases) and control group (39 cases), in addition, 30 case healthy children as healthy control group. The control group children were treated with domperidone suspension 0.3 mg x kg(-1) x d(-1), tid, orally 30 minutes before meals. Treatment group were treated with child anorexia granule, 1-3 years 1 package, bid; 4-6 years 1 package, tid; po, 4 weeks as a course of treatment. Study the change of serum ghrelin and leptin before and after therapy. The study demonstrates that before treatment, the serum ghrelin level of disease group was lower than healthy group (P < 0.01), and the serum leptin level was higher than healthy group (P < 0.01). After treatment, the serum ghrelin level both increase, and the serum leptin decline. And the change of treatment group was significantly different with control group (P < 0.01). And the clinical effective rate are 95.23% and 74.35% (P < 0.01). After 6 months of follow-up visit, the children weight significantly increase in treatment group (P < 0.01). Results indicate that child anorexia granule can facilitate secretion of ghrelin, and inhibit secretion of leptin, so as to work up an appetite. And the molecular mechanism is its infect on serum ghrelin, leptin.

To evaluate the application of intracavitary three-dimensional ultrasonography in the diagnosis of polycystic ovary syndrome ( PCOS). The three-dimensional volumes of ovary were measured by intracavitary ultrasonography in 40 PCOS patients and 40 normal controls. The diagnostic value of parameters derived from three-dimensional ultrasonography was evaluated by using the receiver operating characteristic (ROC) curve. The ovarian volume, stromal volume, and the stromal/total volume ratio in PCOS group were significantly higher than those in control group (both P < 0. 05 ) ; the area under ROC curve ( AUC ) of them were 0. 876, 0. 926, 0. 886 respectively. Among these parameters, stromal volume had the highest diagnostic value for PCOS, the cut-off value of which was 7.52 cm3 with a sensitivity of 88% and a specificity of 90%. Volume parameters of ovary measured by intracavitary three-dimensional ultrasonography can offer quantitative information for the diagnosis of PCOS.

OBJECTIVETo invesitigate the clinical effects of percutaneous closed reduction and cannulated screw internal fixation combined with external fixation in the treatment of unstable pelvic fractures.
METHODSFrom April 2006 to May 2009,29 patients with pelvic fractures of rotatory instability were treated with closed reduction and screw internal fixation combined with external fixation. There were 19 males and 10 females with an average age of 31 years old (ranged from 19 to 53 years). Based on the Tile classification,17 cases were type CI and 12 case were type C2. Tornetta standard and Majeed score were used to evaluated the clinical effect after operation.
RESULTSAll patients were followed up from 10 to 24 months with an average of 16 months. There were no nerve injuries and other organ injuries, only one case of infection was found and it was cured with wound dressing. Time of fracture union was from 14 to 18 weeks with the mean of 16.2 weeks. No loosening, slippage or breakage of the screw were found. According to the Tornetta standards,14 cases obtained excellent results, 10 good, 4 fair and 1 poor. The Majeed score was 87.2 ± 11.3, 16 cases got excellent results, 9 good and 4 fair.
CONCLUSIONClosed reduction and screw internal fixation combined with external fixation is an effective way to treat unstable pelvic fractures with Tile type C1 and Tile type C2.

ObjectiveTo investigate the action mechanism of CD20 lymphocyte infiltration in the renal allograft biopsy with chronic allograft nephropathy (CAN).MethodsCAN cases confirmed by renal biopsy within 2 years after renal transplantation served as study subjects. By using immunohistochemistry,the deposition of C4d and the CD20-positive lymphocytes infiltration in the renal grafts were examined.The clinical follow-up data were analyzed.ResultsForty-four cases of CAN were enrolled in the study, including 13 cases (29.5% ) of CD20-positive lymphocytes infiltration,and 31cases (70.5% )of CD20-negative lymphocytes infiltration. CD20-positive lymphocytes in biopsy showed nodular and scattered lymphocytes infiltration.There were 5 (26.3%)cases of CAN Ⅰ,4 cases (25.0%) of CAN Ⅱ,and 4 (44.4%) of CAN Ⅲ in CD20-positive group.There was no statistically significant difference between the only CAN group and CAN with AR group in CD20-positive rate.Immunohistochemical staining showed there were 12 cases (27.3%) with C4d linear deposition in peritubular capillary endothelial cells (PTC).C4d positive rate had no significant difference among the CAN classifications. There was no significant relationship between C4d deposition and CD20-positive lymphocytic infiltration.The average serum creatinine in CD20-negtive group and CD20-posigtive group was 140.8 ± 22.0 and 183.5 ± 25.5μmol/L before biopsy,and 165.6 ± 37.6 and 242.2 ± 59.1 μmol/L one year after biopsy.The average serum creatinine level in CD20-positive group was higher than in CD20-negtive group before and after biopsy.ConclusionProgressive chronic humoral immunity is high risk in the process of CAN. The CD20-positive lymphocyte infiltration has no relevance with CAN grade and C4d deposition in PTC,but is associated with circulating antibody PRA and allograft long-term outcome. Pathogenetic mechanism may not contribute to chronic humoral immune,but B cells presenting donor antigens,are recognized and activated by T cells as antigen-presenting cells.

Objective To evaluate the value of three-dimensional power Doppler imaging(3D-PDI) in the discrimination between benign and malignant endometrium in women with postmenopausal bleeding. Methods Eighty-four women with post menopausal bleeding who examined by 3D-PDI were enrolled. All patients scheduled for pathological examination were divided into benign group (30 cases with endometrial polyps and 34 cases with hyperplasia) and malignant group (20 cases with endometrial carcinoma). Endometrial volume, vascularity index ( VI) , flow index ( FI) and vascularity flow index ( VFI) were measured. The diagnostic value of parameters derived from 3D-PDI was evaluated by using the receiver operating characteristic ( ROC) curve. Results Differences of these parameters (VI, FI and VFI) were considered statistically significant between two groups, the parameters of endometrial volume had no significant differences between two groups; the area under ROC curve(AUC) of the meaningful data were 0.976,0.888 and 0.894 respectively. Among these parameters, VI had the highest diagnostic value for discriminating between benign and malignant endometrium, the cut-off value of which was 2. 97 with a sensitivity of 95% and a specificity of 86%. Conclusions 3D-PDI is a good diagnostic tools in the discriminations between benign and malignant endometrium in women with postmenopausal bleeding.
