Objective To probe the changes of RAGEmRNA expression in renal tissue of.streptozotocin (STZ)-induced diabetic rats. Methods Quantitative reverse transcription polymerase chain reaction (RT-PCR) was used in control rats and diabetic rats for 12 weeks. Results After 4 weeks of diabetes inducement, RACEmRNA level showed a continuous increase both in diabetic renal cortex and medulla. However, this enhancement could not be observed in 2 weeks of diabetes. In addition, after 8 weeks diabetic rats had significantly higher glycated Hb(GHb). Conclusion Gene expression of RAGE in renal tissue of diabetic rats is altered and the excessive gene expression of RAGE may enhance the AGEs-RAGE interactions which would contribute to the development of diabetic nephropathy. Furthermore, this change occurs as a result of hyperglycemia-induced AGEs formation.

Objective To explore the use of integrated two methods in vitro in prediction of eye irritation caused by cosmetics.Method Chorioallantoic membrane vascular assay ( CAMVA), bovine corneal opacity and permeability (BCOP) and Draize rabbit eye irritation test were used to determine the predictive potential of eye irritation of 60 kinds of cosmetics.Results CAMVA method was able to distinguish 41 non-irritant samples and 18 irritant samples.BCOP method was able to predict 35 non-irritant samples , 21 mild-moderate irritant samples and 4 severe irritant samples . Combination of CAMVA and BCOP methods could obviously improve the identification ability of irritation , and the classification consistency with Draize rabbit eye irritation testing reached 98.3%.Conclusions The integrated test strategy combined BCOP with CAMVA can be used to appropriately predict ocular irritation of cosmetics , with a prediction range covering non-irritant to severe irritant samples .

Objective To explore the methods of diagnosis and appropriate treatment of pancreatic duct stone.Methods Clinical data of 16 patients with pancreatic duct stone from March,2005 to August,2009 were analyzed retrospectively.Results 15 patients presented with varying degrees of upper abdominal pain,another one with irregular diarrhea.Serum and urine amylase level was higher than the upper limit of normal level in 3 patients;serum glucose was elevated in 4 patients.The diagnostic accuracy by Bultrasonography,CT,MRI,ERCP and KUB was 93.8%(15/16),68.8% (11/16),57.1% (4/7);100%(2/2) and 50% (3/6),respectively.2 cases underwent endoscopic pancreatic sphincterotomy + pancreatic stent drainage,14 cases were treated with surgery,including transpancreatic duct lithotomy + pancreatic jejunal anastomosis in 12 cases,pancreatoduodenectomy in 1 ease,and pancreatic body and tail resection +pancreatic jejunal Roux-en-Y anastomosis in one case.All operations were successful without mortality,and abdominal pain was significantly improved.Follow up of 14 cases showed no stone recurrence.Two patients were lost in follow up,so the follow up rate was 87.5% with the duration ranging from 1 to 53 months.Conclusions B-ultrasonography was the best imaging examination for pancreatic duet stone,but the combined application of imaging tests could significantly improve the diagnostic yield,and imaging examination provided an important basis for the choice of treatment method.With the improvement of endoscopic techniques,ERCP will be as important as surgery for the treatment of pancreatic duct stone.

Objective To investigate the diagnosis and surgical treatment of pancreatic cystic tumor.Methods The clinical data of 19 cases of pancreatic cystic tumor from January 2000 to August 2009 was retrospectively analyzed. Results Patients with pancreatic cystic tumor has no specific clinical feature.Ultrasound and CT were main image examinations, but they could not distinguish the pathologic types, and the diagnostic accuracy when compared with postoperative pathologic results was 57.9% (11/19) and 68.4%(13/19) respectively. The tumors were located in the pancreatic head and neck in 5 cases, body and tail in 14 cases, the maxim diameter was between 3 ～ 15 cm. All patients underwent surgical treatment; the rate of curative resection was 84. 2% ( 16/19 ). The rate of intraoperative misdiagnosis was 21.0% ( 4/19 ).Pathologic examination results showed 6 cases of serous cystadenoma, 6 cases of mucinous cystadenoma, 5 cases of mucinous cystadenocarcinoma, and 2 cases of intraductal papillary mucinous adenoma. 15 ( 78.9% )patients were followed up. Among the 3 patients with mucinous cystadenocarcinoma, one patient who received curative resection survived for 4 years with no evidence of recurrence; the other 2 patients died 4 months and 7 months later. 12 cases of cystadenoma were alive without recurrence. Four patients, including 2 patients of cystadenoma and 2 patients of cystadenocarcinoma were lost in follow-up. Conclusions To be aware of pancreatic cystic tumors is the key to reduce misdiagnosis and mistreatment. Surgical treatment is the treatment of choice with excellent prognosis.

BACKGROUND:Pedicle screw fixation has been used in children with thoracic injury. Conventional method is screw implantation by hand. This method can meet the needs of surgery, but its accuracy was low, and incidence of complications was high. The application of digital image navigation aid module is possible. OBJECTIVE:To study accuracy and safety of digital image navigation aid module in thoracic pedicle screw placement. METHODS:Eight thoracic vertebral bodies were equal y and randomly assigned to the manual insertion group and the digital image navigation aid module group. Manual insertion group received manual screw insertion. In the digital image navigation aid module group, navigation aid module was made according to CT scan results combined with principle of reverse engineering and rapid prototyping. Pedicle screw was placed using the digital image navigation aid module. RESULTS AND CONCLUSION:(1) Success rate of once screw set was significantly higher in the digital imaging navigation aid module group than in the manual insertion group (P<0.05). (2) Twenty-eight screws were implanted in the digital image navigation aid module group and manual insertion group separately. The excellent and good rate of screw placement was 96%in the digital image navigation aid module group and 75%in the manual insertion group (P<0.05). (3) These findings suggested that digital image navigation aid module can effectively improve the success rate of pedicle screw insertion. Moreover, this method is simple, easy to operate, and can make a personalized nail placement program for each child.

Objective:To study the use of three-dimensional computer reconstruction in diagnosis and treatment of hilar cholangiocarcinoma.Methods:A retrospective analysis of clinical data was conducted on patients with hilar cholangiocarcinoma admitted to the Department of General Surgery, the First Affiliated Hospital of the University of Science and Technology of China from January 1, 2017 to July 31, 2019. The classification of hilar cholangiocarcinoma, vascular invasion and surgical resectability were determined by preoperative three-dimensional reconstruction. These data were then compared with the findings obtained during operations, by comparing with the three-dimensional reconstruction technology findings in classification of hilar cholangiocarcinoma, vascular invasion, and hilar extent of biliary and vasculature involvement.Results:Of 65 patients included in this study, there were 35 males and 30 females, with an age of (60.35±10.70) years. After operation, these 65 patients were classified into type I ( n=7), type II ( n=4), type III ( n=14), and type IV ( n=40) using the Bismuth classification. The accuracy rates of preoperative three-dimensional reconstruction for hilar cholangiocarcinoma classification, portal vein invasion, hepatic artery invasion, and diagnosis of hilar cholangiocarcinoma vasculature involvement were 90.7% (59/65), 90.7% (59/65), 86.1% (56/65) and 80.0% (52/65) respectively. Conclusions:The three-dimensional computer reconstruction technology could visually and accurately display the shape and spatial extent of hilar cholangiocarcinoma. It has an important clinical use in accurately diagnosing hilar cholangiocarcinoma preoperatively.
