The spceics identification by the hemoglobin band patterns in blood stains using isoelectric focusing with amphotine made in China is reported. Forty different sorts of bloodstain from human and animals were studied. Although the ability of species identification of hemogolbin band patterns in blood stains is lower than those in hemolysates, but the indentification of humen blood stain and the blood stains from most different spcies of animads were achieved. With the exception blood stain indintification between human adult foetus and monkey as well as between five groups in classes of bird and fish Human adult blood stain could be distinguished much easily from animal's blood stains but not from human foetus ,if the blood stairis were pretreated with PCMB. It is concluded that the species indentification of blood staine using isoelectice focusing with ampholinemade in china is possible.

Purpose To summarize the CT features and clinical characteristics of atypical primary fallopian tube cancer (PCFT) and ovarian cystadenocarcinoma (OCA), in order to improved the diagnosis. Materials and Methods CT findings and clinical data of 12 patients with atypical PCFT (PCFT group) and 20 patients with OCA (OCA group) were retrospectively studied. All patients were confirmed by pathology. Serum CA125 level, clinical characteristics and CT features of two groups were compared. Results Serum CA125 level of PCFT group and OCA group were (486.13±23.89) U/ml and (1606.94±62.86) U/ml, respectively. There was statistic difference between the two groups (P<0.01). There was significant differences on vaginal bleeding and vaginal discharge between the two groups (P<0.01). There were 4 cases with solid mass, 8 cases with cystic solid mass in PCFT group. And in OCA group, 16 cases with cystic solid mass and 4 cases with cystic mass were revealed, which showed statistic differences between the two groups (P<0.05). Some other findings also showed statistic differences including the diameter of ovarian vein on the affected side, the diameter of the round ligament of uterus on the affected side, tumor volume, and CT values of the mass in venous phase and delay phase (P<0.05 or P<0.01). However, there were no statistic significance in the size of metastatic lymph nodes, the mean CT value of the mass on plain scan and in the arterial phase (P>0.05). Conclusion Clinical findings of serum CA125 level, vaginal bleeding, and vaginal discharge combine with imaging findings of diameter of the ovarian vein in the affected side, diameter of ipsilateral round ligament of uterus, tumor volume, CT values of the mass in venous and delay phase would be the key points for differential diagnosis of PCFT and OCA.

Objective To introduce a new computer-assisted external frame for osteotomy to correct complex tibial and fibular deformity.Methods From January 2012 to December 2013,15 patients with complex tibial and fibular deformity were treated with a computer-assisted external frame and related computer software for surgical correction.All were unilateral limb deformity,involving the left lower limb in 8 cases and the right lower limb in 7 cases.They were 8 males and 7 females,15 to 43 years of age (average,26.8 years).The deformity was caused by old osteomyelitis in 9 cases and trauma sequela in 6.The related angles,distances and rotations were measured on the postoperative radiographs of the lower limbs.The data were input into the software to calculate the daily adjustment lengths of the frame rods.Daily frame adjustments were conducted according to the data calculated.The frame was removed when expected results were achieved.The patients lived independently during the adjustment.Results The 15 patients were effectively followed up for 10 to 22 months (average,15 months).Frame fixation time averaged 8.4 months (from 5.5 to 13.1 months).The reunion time averaged 8.0 months (from 5.4 to 12.1 months).The hospitalization time averaged 2.4 months (from 2.0 to 2.8 months).In 10 cases of limb shortening,the shortening lengths averaged 0.5 cm (from 0 to 0.9 cm) after adjustment.In 12 cases of angulation deformity,the angulation averaged 3.3° (from 0° to 5.4°) after adjustment.In 5 cases of rotation deformity,the maximum internal rotation was 5° and the maximum external rotation 10° after correction,deviating from the normal values by 3.5° on average.In 6 cases of horizontal displacement,the displacements averaged 0.5 crn after correction.All patients were satisfactory with corrected lower limb alignment,improved symptoms and appearance,giving a subjective satisfaction rate of 100％.Conclusion Use of computer-assisted external frame in surgical correction of tibial and fibular deformity can achieve satisfactory outcomes in simple,accurate,standardized,minimally invasive manners.

The weight ofthe assessment indexes was obtained through a statistical analysis of the results. Hence the pre iluninary establishment of the system of standards for assessing the managing capacity of hospital directors.

AimTo study the anti-inflammatory effect of astragalosides(AST) and its mechanisms of action. Methods The exudate volume, neutrophil count and protein content in exudate were measuredinthe carrageenan-induced air pounch model in rats. The content of PGE2 was assayed by radioimmunoassay,the activity of PLA2 by microacid titration assay, IL-8 by ELISA, and NO by nitrate reductase assay. The production of O2 in neutrophil was determined by cytochrome C assay. Results AST(40, 80 mg· kg -1) could markedly reduce the exudate volume, neutrophil count, protein content, the content of IL-8, and the production of O2.AST lowered PLA2 activity of neutrophil and accellular component in exudate, and it also decreased the contents of PGE2 and NO in exudate. Conclusion AST has an obvious anti-inflammatory effect on carrageenan-induced acute inflammation.Its mechanisms may be related to the inhibition of vascular permeability and leukocyte migration, as well as to the suppression of PLA2 activity and the reduction of IL-8, PGE2, NO and O2 production.

Objective To evaluate the CT features of primary adrenal lymphoma and its relationship with pathology.Methods Pathologically proven primary adrenal lymphoma 6 cases were reviewed.There were 4 males and 2 females.The age was 18-62 years,average age was 51 years.5 cases was single tomur in unilateral,1 case was bilateral disease.The main clinical manifestations were abdominal pain,abdominal discomfort.All patients had CT scan and were treated surgically.Results CT scan showed the characters of adrenal little low-density soft tissue mass:the maximum diameter of 3-11 cm,irregularly shaped or ovalshaped,multi-state a clear,homogeneous or slightly inhomogeneous density,CT value was 30-40 HU.Lesions could be embedded or close to blood vessels and the ipsilateral kidney.The lesions were not enhanced arterial phase enhancement,CT value was 39-50 HU.The lesions showed vein phase of mild to moderate enhancement,CT value was 47-66 HU.At the delay of continuing to strengthen phase,CT value was 60-78 HU.The pathology charaters showed that:Diffuse of tumor cells under light microscope dense,more uniform size,and a large,granular chromatin,tumor stromal components was relatively small.There was no significant bleeding,necrosis and calcification.one lesion showed sheet,tumor cell necrosis.Conclusions CT scan characteristics and pathological features of primary adrenal lymphoma might have a certain correlation.
