1.CT-guided percutaneous biopsy of sacral lesions
Journal of Interventional Radiology 1994;0(03):-
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.
2.Correlation of methylation of E-cad gene with gastrointestinal cancer
Journal of International Oncology 2011;38(2):145-147
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.

4.The functional anatomy of internal carotid artery and the possible utility of intracranial covered stent in ICA to treat vascular diseases
Journal of Interventional Radiology 2001;0(05):-
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.

Chinese Journal of Biochemical Pharmaceutics 2015;(8):167-169
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.
6.Angiogenesis and cellular source of artery after PTA
Journal of Interventional Radiology 1992;0(01):-
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.
7.Relationship between Environmental Endocrine Disruptors, Genetic Polymorphism of Related Metabolic Enzymes and Breast Cancer
Journal of Environment and Health 1992;0(02):-
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 potential effect of gene-environment interaction between glutathione S-transferase M1 (GSTM1) and serum organochlorines residues on the risk of breast cancer in women, in China. Methods Seventy newly pathologically diagnosed female patients with breast cancer from September 2006 to October 2007 were selected as the cases from five large hospitals in Tangshan. The controls were identified at the same hospital as cases. 1∶1 matched case-control study. Between the cases and controls, the difference of age was not over two years and the residence was similar. The organochlorine residues levels in the serum were measured by gas chromatography (GC). Genotypes of GSTM1 polymorphisms were analyzed by multiplex allele-specific polymerase chain reaction (PCR). Interaction indexes (?) were calculated to determine the type of gene-environment interaction. Results After confounding factors adjusted, the result showed that interaction existed in genetic polymorphisms of GSTM1 and DDT, HCH residues, and interaction indexes (?) value were 1.237 and 1.379. Conclusion GSTM1 genetic polymorphisms and DDT, HCH may present an interaction in the development of breast cancer.
