Objective To evaluate the value of ultrasonic diagnosis of congenital prepyloric diaphragm. Methods Twelve cases were collected for the analysis of the characteristics of ultrasonography in diagnosis of congenital prepyloric diaphragm. Results Of the 12 cases of congenital prepyloric diaphragm, valvula in pyloric antrum could be observed in 5 cases, inclusive of 2 cases of complicating pachyntic stenosis of pyloric muscular layer. Other valvula in pyloric canal could not be found with ultrasonography. No pyloric muscular layer pachynsis was observed, but signs of pyloric obstruction such as gastric retention, slow or difficult transfer of gastric contents, gastro-esophageal reflux were found. Prepyloric diaphragm was confirmed surgically in all cases. Conclusion Ultrasonic diagnosis of congenital prepyloric diaphragm is of practical value in clinical practice and can provide reliable imaging data for the option of preoperative approaches.

Objective To study retrospectively the efficacy and complications of different surgery approaches used to treat primary spinal tumors and to discuss the surgical strategy in treating them. Methods 135 patients with primary spinal tumors had been treated between July 1998 and July 2005. The following diagnoses were made based on histopathological findings: multiple myeloma in 25 patients, giant cell tumor in 17, neurofibroma or neurilemmoma in 23, chondrosarcoma in 7, osteoblastoma in 6, aneurysmal bone cyst in 4, lymphoma in 9, eosinophilic granuloma in 6, hemangioma in 15, osteosarcoma in 3, Ewing sarcoma in 5, and other different tumors in 15. Anterior approach and posterior approach was used in 73 cases and 31 cases respectively. Posterolateral approach was used in 13 cases and combination of anterior and posterior approach was used in 18 cases. Results Pain relief was obtained in 126 of the 135 patients(93.3%). Improved neurological function was seen in 86 of 92 patients who had suffered from impaired neurological function. No severe complications were found in the follow-up period. Cerebrospinal fluid leakage was observed in 11 patients, and which was successfully treated using antibiotics therapy and raising the foot of the bed. 3 patients suffered from stress ulcer after operation, but they recovered soon after blood transfusion and anti-acid treatment. Other complications included subcutaneous emphysema (in 3 patients), superficial wound infection (in 3 patients),nerve root injury (in 2 patients), implant loosening (in 2 patients), and neurological morbidity due to surgery (in 1 patient). Conclusion When single or two adjacent vertebrae are involved by spinal tumors such as giant cell tumor and chondrosarcoma, tumor resection should be performed through combination of anterior and posterior approach. Aggressive resection based on the Tomita or WBB staging system is the treatment most likely to achieve long-term local control.

Objective To investigate the expression of glioma-associated oncogene 2 (Gli2) in giant cell tumor of bone, and analyze the differential expression in the different classification of imaging and pathology and the recurrent diseases, to discuss its role and significance in the pathogenesis and prognosis of giant cell tumor of bone. Methods 46 cases of giant cell tumor of bone who received the primary treatment in Peking University Peopleˊs Hospital during Jan 2009 and Dec 2012 and had the full data of treatment and could be follow-up were collected. Among which there were 40 benign cases and 6 malignant cases. The expression of Gli2 in the different cases of giant cell tumor of bone were detected by immunohistochemistry and real-time PCR, and its effect on the prognosis of giant cell tumor of bone was analyzed. Results Immunohistochemistry revealed positive expression of Gli2 in giant cell tumor of bone. The positive rate of Gli2 in malignant cases was significantly higher than that in benign cases [100.0 % (6/6) vs 55.0 % (22/40), P=0.035], and only found increasing trend but no significant difference among recurrent cases (P=0.204). Results of real-time PCR indicated that Gli2 highly expressed in giant cell tumor of bone, and the increasing trend of expression in different pathological types, different image classifications and recurrent cases, but no statistical different were found (all P>0.05). The expression correlation analysis showed that the expression of Gli2 and PTHrP, and the expression of RANKL and OPG either had a significant correlation (both P< 0.05). Additionally the expression of PTHrP and RANKL had a moderate correlation (P<0.05). Conclusions The expression level of Gli2 is high in giant cell tumor of bone, and Gli2 may be involved in recurrence,metastasis and malignant transformation. Gli2 may effect the osteolytic process of giant cell tumor of bone by the regulation mechanism of Gli2-PTHrP-RANKL pathway.

Objective: To observe the effect of vitamin A and iron supplementation on iron status during pregnancy. Methods: 167 pregnant women aged 21～33 years in the second trimester were recruited and randomly allocated to four groups: placebo; vitamin A (1.1 mg/d); iron(60 mg elemental iron); vitamin A and iron, for 10 weeks. Results:The incidences of vitamin A deficiency, anemia and iron depletion were 0.6%,7.8% and 6.2% in the second trimester respectively. Serum VA level was not changed in three supplemented groups but decreased in placebo group. Hemoglobin in all groups before and after supplementation was in normal range, with no significant differences. The improvement in serum ferritin, free erythrocyte proporphyrin and transferrin saturation was better in the group supplemented with VA+Fe than VA or Fe alone. Conclusion: The simultaneous supplementation of vitamin A and iron is better in improvement of iron status than supplementation of vitamin A or iron alone during pregnancy. Improvement of iron status by simultaneous supplementation of pregnant women with vitamin A and iron was better than supplementation with iron or vitamin A alone.

Objective:To label monoclonal anti-GPⅢa antibody (SZ21) with 99 Tcm and evaluate the value of 99 Tcm-SZ-21 for detecting thrombi in vivo.Methods:SZ-21 was modified with 2-iminotholane and labeled with 99 Tcm-GH and radiochemical purity was determined by ITLC-SG.99Tcm-SZ-21 was injected via ear edge vein in 5 rabbits in which thrombi were induced in the right femoral arteries.As control,99 Tcm-GH was administered in 1 rabbit.Static images were acquired and irregularly shaped ROIs were drawn on the images to calculate the ratios of T/M and T/B.Vein blood was drawn at 2 min,5 min,10 min,30 min and 1 h-3 h after injection in 2 rabbits so as to observe the blood clearance of 99 Tcm-SZ-21.Rabbits were sacrificed after 3 h of imaging.The vessels including clots were harvested and imaged.Cardiac muscle,liver,spleen,lung,kidney,etc.were excised and weighed.Radioactivity counts were measured to calculate % ID/g.Results:The radiochemical purity of 99 Tcm-SZ21 was beyond 90% and stable in vitro.Thrombi could be visualized at 30 min after injection,and at 2 h image of thrombi was clearly visualized,T/M (2.55?0.72) and T/B (1.94?0.51) ratios were high.In vitro imaging showed that T/B was 4.43?1.5.Conclusion:99Tcm-SZ-21 could be a potential agent for imaging diagnosis of thrombotic disease.

Recent studies have showed that nanotechnology pro-vides a new revolution for the treatment of complex,refractory autoimmune or inflammatory diseases.Nanoparticles combined with specific autoantigens can restore the peripheral tolerance and reduce immunopathological damage in a variety of autoimmune disease models.In this paper,we review the progress and trends of nanomedcine for treatment of autoimmune or inflammatory dis-eases as immunomodulatory therapy from the physical and chemi-cal characteristics of nanoparticles,the route of administration, and the role and mechanism of induction or reconstitution of im-mune tolerance,which provides a theoretical basis for seeking new treatments to treat inflammatory diseases.

Fasting plasma preptin level was assayed by RIA in the patients with different glucose tolerances. Regarding fasting plasma preptin levels, it was higher in females than in males. Fasting plasma preptin level was increased in patients with type 2 diabetes as compared with subjects of impaired glucose tolerance and normal controls, and there were positive correlations with diastolic blood pressure, blood triglyceride, total cholesterol, high-density lipoprotein-cholesterol, free fatty acids, 2 h plasma glucose after glucose load, HbA1C and HOMA-IR, suggesting a potential link between preptin and glucose-lipid metabolism and insulin resistance.

AIM: To investigate the effects of lipid-induced insulin resistance on plasma resistin and ghrelin levels in awake rats. METHODS: A hyperinsulinaemic-euglycaemic clamp was established in awake chronically catheterized rats. Two groups of rats were studied either with a 4 h intraarterial infusion of lipid/heparin or saline. Insulin-mediated peripheral and hepatic glucose metabolism was assessed by insulin clamp combined with [~3H]-glucose infusion, and plasma resistin and ghrelin concentrations were examined before and after clamp with ELISA. RESULTS: During clamp, there was a significant increase in plasma free fatty acid (FFA, P
