Objective To investigate the detection of central venous oxygen saturation ( ScvO2 ) whether can be alternative mixed venous oxygen saturation ( SvO2 ) in elderly patients with acute left ventricular failure.Methods 42 elderly patients with acute heart failure were detected by central venous oxygen saturation and mixed venous oxy-gen saturation before the treatment and 1h,2h,4h after treatment.Then the parameters index changes were analyzed according to the prognosis.Results Whatever the prognosis of the patients were,the trend of ScvO2 and SvO2 was the same.Before the treatment,the blood oxygen saturation detected by the ScvO2 with patients was no statistical differ-ence with the ScvO2(t=0.867,P>0.05),and after treatment of 4h the change trend detected of both has also the consistency,no statistical difference (t=0.681,P>0.05) The correlation coefficient r=0.998,and the relationship between ScvO2 and SvO2 confirmed the same clinical significance.Conclusion Considering the factors of trauma, complications,costs and so on,ScvO2 can be used to replace SvO2 in elderly patients with acute left heart failure.

Objective To investigate the relationship of polymorphisms at codons 333 and 637 of TAP-1 allele gene to recurrent condyloma acuminatum (CA) in a Chinese population. Methods Amplificatory refraction mutation system-PCR (ARMS-PCR) was performed to detect TAP1 polymorphic residues at codon 333 in 88 patients with recurrent CA and 81 age- and sampling date-matched controls and at codon 637 in 60 patients with recurrent CA and 60 age- and sampling date-matched controls. Results The frequencies of AA,GG and AG genotypes at codon 333 of TAP-1 gene were 86.36%, 0, 13.64%, respectively, in patients with recurrent CA, 79.01%, 0 and 20.99%, respectively, in the controls, and no significant difference was observed between the two groups (χ2 = 1.604, P ＞ 0.05). However, a significant difference was observed in the frequencies of AA, GG and AG genotypes at codon 637 of TAP-1 gene between the patients and controls (3.33% vs 10.0%, 95.00% vs 60.00%, 1.67% vs 30.00%, χ2 = 21.551, P ＜ 0.01 ). Conclusions The recurrence of CA may be associated with the polymorphism at codon 637, but not with that at codon 333, of TAP-1 gene.

BACKGROUND:Al ogeneic penetrating keratoplasty is the most effective method for treating corneal blindness. However, the incidence of rejections is high after keratoplasty, so it is urgent to develop an immunosuppressive drug with high efficacy and low toxicity. OBJECTIVE:To establish al ogeneic penetrating keratoplasty models and monitor the expression of tumor necrosis factor-αin blank control group and after transforming growth factor-β1 eyedrop during acute rejection period of corneal grafts. METHODS:Al ogeneic penetrating keratoplasty models were established and were randomly divided into blank control group, ciclosporin A group (1%ciclosporin A), and transforming growth factor-β1 group (1μg/ml transforming growth factor-β1 eyedrop). The medications from each group commenced at 1 day after surgery, one eyedrop once, three eyedrops per day. Al the operated eyes were given 0.3%ofloxacin ophthalmic solutions and 0.5%tropicaide ophthalmic solution, three times per day, for 12 days. The corneal grafts were harvested for hematoxylin-eosin staining and immunihistochemical staining (SABC method), to detect tumor necrosis factor-αexpression in corneal grafts. RESULTS AND CONCLUSION:Hematoxylin-eosin staining showed that, corneal grafts were significantly thickened, a large number of histoleucocytes and lymphocytes infiltrated in the blank control group;corneal grafts showed normal thickness and no inflammatory cel s infiltrated in the transforming growth factor-β1 group. Immunohistochemical staining showed that, there were less cel s positive for tumor necrosis factor-αin the transforming growth factor-β1 group compared with the blank control group (P<0.05). Transforming growth factor-β1 eyedrops can reduce the expression of tumor necrosis factor-αin the corneal grafts during acute rejection period, and reduce the inflammatory cel s infiltration in the corneal grafts, which is probably the mechanism of transforming growth factor-β1 to prevent and treat corneal al ograft rejection.

Objective To compare the differences of blood glucose detected by four methods with different instruments and specimen types at early stage in severely burned rats.Methods 24 Sprague-Dawley (SD) rats were randomly divided into two groups:control group 1 (Sham scald group,n=8) and scald injury group 1 (n=16).Blood samples of scald injury group 1 were collected at 12,and 24 hours after scald (n=8,each time).Another 20 SD rats were randomly divided into two groups:control group 2 (Sham scald group,n=10) and scald injury group 2 (n=10).Blood samples of scald injury group 2 were collected at 12 hours after scald.The rats in scald injury group 1 and 2 were placed into scalding water (95.0±0.5)℃ for 15 seconds to model third-degree burn with 30％ total burn surface area (TBSA).The rats in scald injury group 1 were given intraperitoneal injection with normal saline(40 ml/kg) immediately,while those in scald injury group 2 were given intraperitoneal injection with normal saline (40 ml/kg) 6 hours after scald.The rats in Sham scald group 1 and 2 were placed into warm water 37℃ for 15 seconds,and did not received injection.Portable glucometer/caudal artery (vein) blood,portable glucometer/abdominal aorta blood,spectrophotometer/femoral venous plasma,and spectrophotometer/abdominal aorta plasma were used to detect blood glucose.Results ①Compared with Sham scald group 1,the levels of blood glucose detected by portable glucometer/caudal artery (vein) blood and spectrophotometer/femoral venous plasma in scald injury group1 at 12,24 hours after scald were significantly increased(P＜0.05).Compared with Sham scald group 2,the levels of blood glucose detected by portable glucometer/abdominal aorta blood and spectrophotometer/abdominal aorta plasma in scald injury group 2 at 12 hours after scald were significantly increased(P＜0.05).②The comparison of portable glucometer/caudal artery (vein) blood and spectrophotometer/femoral venous plasma in Sham scald group 1,portable glucometer/abdominal aorta blood and spectrophotometer/abdominal aorta plasma in Sham scald group 2 had no statistical significance (P＞0.05).The levels of blood glucose detected by portable glucometer/caudal artery (vein) blood were significantly lower than those detected by spectrophotometer/femoral venous plasma (P＜0.05) in scald injury group 1.The comparison of blood glucose detected by portable glucometer/abdominal aorta blood and spectrophotometer/abdominal aorta plasma had no statistical significance in scald injury group 2 (P＞0.05).Conclusion Four kinds of methods used in this study shows that the levels of blood glucose were significantly increased at early stage in severely burned rats,and the portable glucometer/abdominal aorta blood is a relatively simple and fast method to detect blood glucose.

Objective To investigate the CT and MRI features of the autoimmune pancreatitis (ALP).Methods CT and MRI data of fourteen patients with AIP who were confirmed by histology and/or steroid therapy were retrospectively analyzed.Ten patients underwent CT examination, and seven patients underwent MRI, while three patients underwent both CT and MRI examinations.Results It was showed that diffuse (n =11 ) or local ( n = 3 ) enlargement of pancreas.CT features showed that the hypoattenuation pancreatic lesions on unenhanced CT (n = 10);segmental pancreatic duct could be seen in five patients;stenosis of common bile duct in the head of pancreas was observed in 5 patients;the capsule-like structure around lesions was seen in seven patients.Delayed homogeneous enhancement was showed on enhanced CT.MRI features included homogeneous ( n = 3) and heterogeneous ( n = 4) hyperintense on T1 WI with fat-suppression images and homogeneous ( n = 3 )and heterogeneous (n =4) hyperintense on T2WI with fat-suppression images.Pancreatic duct could be seen in four patients.MRCP showed pancreatic duct stenosis in the head of pancreas ( n = 1 ) and segmental pancreatic duct (n = 2).Stenosis of common bile duct in the head of pancreas was showed in 5 cases.The capsule-like structure around lesions was showed in seven patients.No pancreatic calcification was revealed, and no significant pancreatic duct dilation was detected ( ＞3 mm) in all 14 patients.Conclusions The CT and MRI manifestations of AIP had characteristic features such as sausage-like changes of the pancreas, capsule-like structure around the lesions, diffuse or local pancreatic duct stricture, and stenosis of common bile duct in the bead of pancreas.

Objective To evaluate the diagnosis and treatment of cystic renal cell carcinoma and to improve the preoperative diagnosis and curative rate of the disease. Methods Ten cases of cystic renal cell carcinoma were retrospectively analyzed in the aspects of imaging and pathologic characteristics. There were 7 males and 3 females with average age of 56 years old (ranging from 38--74 years old) in this study. There were 3 cases complained of sore waist, 7 cases were found renal masses in annual physical examination and 2 cases had the history of renal cysts. The cyst diameter was 3.5 8.2 cm. Six cases had been diagnosed with ultrasound and 7 cases had been diagnosed with CT scan pre-operatively. Eight eases were diagnosed with frozen section during operation. All the 10 cases accepted radical nephreetomies. Results The post-operative histological diagnosis showed that there were 9 cases of clear cell carcinoma and 1 case of granular cell carcinoma. The pathological character istics were tumor necrosis of renal cell carcinoma in 6 cases, multilocular cystic renal cell carcinoma in 2 cases and carcinoma in renal cyst in 2 cases. Eight patients followed up from 6 months to 5 years. Six patients were still alive (mean 28.5 months). Conclusion The keys to improve the diagnosis and curative rate of the cystic renal cell carcinoma are paying attention to the pre-operative imaging study, the intra-operative frozen section examination and histopathology results.

Objective To assess the respective value and limitation of cardioangiography and ultrasonography in interventional therapy for congenital heart disease in children,and to discuss the clinical significance of the combined use of both examinations. Methods A total of 162 children with congenital heart disease,screened by ultrasonography,were enrolled in this study.The disorders included VSD(n=50),PDA(n=96)and PS(n=16).Before the interventional therapy all the cases accepted cardioangiography and ultrasonography examinations,and the diameter of the abnormal passage was measured.The difference in the diameter between two examinations was compared and statistically analyzed by using paired t test.All the cases accepted both examinations after the interventional therapy to check the location of the occluder and the result of balloon dilatation.Results Both cardiovascular angiography and ultrasonography could make a definite diagnosis of congenital bean disease in children,and could well display the location and shape of the abnormalities.The diameter of VSD(n=50)measured by cardioangiography and ultrasonography was(4.93±2.73)mm and(5.66±2.77)mm respectively,with no significant statistical difference existing between two methods(P＞0.05).The diameter at the narrowest site of PDA(n=96)measured by cardioangiography and ultrasonography was(3.22±1.45)mm and(3.96±1.42)mm respectively,with a significant difference existing between two methods(P＜0.05).In 16 PS cases,the diameter of valvular ring determined on cardioangiogram and on ultrasonogram wag(16.16±4.26)mm and(17.94±5.50)mm respectively,with no significant difference between two groups(P＞0.05).During the operation of VSD,the monitoring ultrasonography revealed that the valvular opening and closing was interfered by the occluder in 9 cases,so the occluder was re-adjusted till it was fixed to proper position. After the interventional therapy for VSD and PDA,cardioangiography detected a small residual shunt in 7 cases,which completely disappeared 24 hours later on ultrasonography.After balloon dilation in all 16 children with PS the right ventricle-pulmonary artery pressure difference was reduced by more than 50%and the pressure figure reached the standard of clinical Cure.The interventional procedure was successfully completed in all patients except for three cases. Conclusion In treating children of congenital heart disease with interventional procedures,the determination of the lesion's diameter and the selection of the occluder should be based on cardioangiographic measurement,although ultrasonography is more helpful in making preoperative screening and postoperative evaluation.
