Objective To improve both the technique and the clinical application of CT-guided percutaneous aspiration biopsy for sacral lesions. Methods CT-guided percutaneous aspiration biopsy was performed in 21 patients with sacral lesions. By using Ackerman drilling needle, trigger type biopsy needle or Chiba needle, both bony and non-bony specimens were collected. Results The procedure was successfully done in all patients and the pathologic diagnosis was obtained in 95.2%. Failure occurred in one case as only necrotic tissue and blood clot were collected in biopsy. Conclusion As a simple, safe and reliable technique, CT-guided percutaneous aspiration biopsy is very helpful in making correct preoperative diagnosis, providing important preoperative reference for the surgeons.

It is difficult to treat the internal carotid arterial (ICA) wall disease between C2 to C7 segment ( the definition of ICA by E. Bouthillier,1996) with present interventional radiological measurements , includling pseudoaneurysm, giant or wide neck aneurysm and complicated carotid cavernous fistula. Some literatures have reported a few cases treated with coronary covered stent (e.g. Jomed coronary stent, Symbiot coronary stent), with favorable results . However, these kinds of coronary covered stents are too rigid, with uneasinees to pass through in tortuous ICA, and often resulting in injury of vascular wall. The utility of covered stent in intracranial artery also caused controversies of exclusion of origins of arterial branches. We analyzed the functional anatomy of ICA and reviewed our experimental results and primarily clinical application on professional intracranial covered stent with special designed structure and delivery system for ICA, in order to explore the possibility of utility of covered stent in intracranial arteries.

The methylation of CpG island in promoter region of E-cad gene which usually leads to inactivation of E-cad gene is closely related to the occurrence, development, invasion, metastasis and prognosis of a variety of gastrointestinal cancer, such as esophageal carcinoma, gastric carcinoma, hepatocellular carcinoma,cholangiocellular carcinoma, carcinoma of gallbladder, pancreatic carcinoma and colorectal cancer. Further study would probably guide the early diagnosis, gene therapy, prophylaxis and predicting recurrence of tumor metastasis of gastrointestinal cancer.

Objective To investigate effect of Splenic Aminopeptide Oral Lyophilized Powder on urinary retinol-binding protein and CRP in children of mycoplasma pneumonia infection with asthma .Methods 60 cases were randomly divided into 2 groups, 30 cases of control group were given conventional anti-inflammatory treatment, azithromycin.30 patients of Experimental group were treated with Spleen Aminopeptide Oral Lyophilized Powder treatment, two groups were treated for 7 days.30 cases of healthy children were selected, given no any treatment.After treatment, urinary retinol binding protein, blood urea nitrogen, creatinine, cough, wheezing symptom recovery, C-reactive protein, blood and other changes were compared between two groups.ResuIts Two groups of children with urinary retinol binding protein, urea nitrogen, creatinine levels were improved in different degrees, and in experimental group, urinary retinol binding protein, urea nitrogen and creatinine decreased significantly compared with control group (P<0.05).Two groups of children with asthma and wheeze improved in different degrees, and cough wheeze, cough and wheeze recovery time of experimental group had more improvement than those of control group ( P<0.05 ) .Two group of C reactive protein and white blood cell level both improved in different degrees, and the experimental group of C reactive protein and white blood cell levels were significantly lower than those of control group (P<0.05).ConcIusion Spleen Aminopeptide Oral Lyophilized Powder can significantly improve the infection status of children with mycoplasma pneumonia, and relieve cough and wheeze symptoms, lower urinary retinol binding protein and C reactive protein level, improve kidney function damage induced by hypoxia.

Objective To discuss the application of nursing care in CT-guided percutaneous biopsy of the pancreas.Methods The perioperative nursing measures were carried out in 21 patients receiving percutaneous biopsy of the pancreas under CT-guidance.Active,effective and comprehensive nursing procedures were adopted to closely cooperate with the whole process of percutaneous biopsy as far as possible.Results All the patients could actively cooperate with the physician during the whole process of percutaneous biopsy and the surgery was successfully completed in all patients.The technical success rate with only single puncture was 100%.No obvious complications occurred after the procedure.Conclusion In order to ensure that the patient will be able to cooperate with the CT-guided percutaneous biopsy of the pancreas,that the operation time can be shortened and that the postoperative complications can be avoided,perioperative nursing care is indispensable.

Phenotypic conversion process of cells in blood vessels occurred after percutaneous transluminal angioplasty (PTA), which is similar to “recall” of angiogenesis. This article is an attempt in reviewing the major themes and more recent findings dealing with the phenotypic conversion and cellular source in three layers of arterial wall after PTA in the adult.

Breast cancer is one of reproduction-endocrine related tumors, so the risk factors including environmental and genetic factors which can disrupt anabolism and function of estradiol may increase the risk of breast cancer. Persistent environmental endocrine disruptor chemical (EDCs) can disrupt anabolism and function of endogenous hormone and the degree of disruption may depend on genetic polymorphism. EDCs and metabolic enzyme genetic polymorphism were discussed in this paper. To study the risk factors of breast cancer, both of the environmental factors and the genetic factors should be included.

Objective To study the changes and significance of HBV DNA and it's antigen and antibody in patients with liver transplanting.Methods 35 cases with liver transplanting in 302th hospital from Oct.2006 to Mac.2007 has been studied.The HBV antigen and antibody has been studied by ELISA in 188 samples including one from before transplanting and 4 to 7 from after transplanting.The quantitative of HBV DNA has been detected by real time PCR technology.45 cases of hepatitis B,whose sera HBV DNA is positive no more than 10 000U/ml,treated with lamifudine in 2 weeks about has been used in controls.Results 95(34/35)percent of liver-transplanting patients acquired serum-transfer in HbsAg to it's antibody,and 6 patients with HBeAg positive acquired from HbeAg to it's antibody in 2 days after transplanting.The HBV DNA in sera is distinguished of 34 cases from 35s in 6 months after liver-translpanting.Only one patient is insisting with HBsAg and HBV DNA positive.In lamifudine treatment controls,none of patients acquired sera-transferred from HBsAg to antibody in 45 cases.The HBV DNA is decreased from positive to negative under cove in 11 controls.29 cases of HBV DNA are decreased in 2 to 3 Log E after treatment with lamifudine.The HBV DNA is insisting in high levels in 5 patients.The HBeAg is negative in 29 cases after lamifudine treatment,but it's antibody is not acquired serum transferring.Conclusion The HBV DNA,HbsAg and HbeAg in patients with HBV infection may be transferred into negative forever transplanting with healthy liver underlined in HBIG and lamfudine treatment.

Objective To study the effect mechanism of anticancer synergic (KangAiZengXiao,KAZX) decoction on gastric cancer in immunologic deficit rats with implanted tumor. Methods Forty rats were divided into normal control group(n=10), model group(n=15) and KAZX treating group(n=15). Model group and KAZX group were subcutaneously injected axillary the left upper limb with 0 5ml gastri cancer cells,MGC-803 cell(1?10 7/ml) after irradiated by 60 Co(dose:10Gy). Then the three groups were treated with KAZX decoction or distilled water every day, respectively. After three weeks, the rats were sacrificed,and blood WBC, the weight of spleen, activity of NK cell and transformation efficiency of lymphocyte were also detected.Results The rate of loaded tumor in KAZX group was significantly lower than in model group(20% vs 66 7%,P
