Purpose To observe the curative effect of interventional therapy by CT localization combined traditional Chinese medicine on prolapse of lumbar intervertebral disc. Method The inpatients of lumbar intervertebral disc prolapse were randomly divided into treatmentgroup and control group. Interventional therapy by CT localization combined TCM was used in the treatment group while in the control group TCM therapy was taken only. The treatment lasted for 10 days in both groups. Results The curative effect was 94.3% in the treatment group while 76.8% in the control one (P < 0.05), which had statistical meaning. Conclusion Interventional therapy by CT localization combined TCM on prolapse of lumbar intervertebral disc had better effect and shorter treatment course.

Objective: To observe the clinical efficacy of acupuncture treatment for migraine. Methods: Forty cases were randomly allocated to a treatment group and a control group, 20 cases in each group. Cases in the treatment group were treated with acupuncture, while cases in the control group were treated with oral Sibelium. After that, the changes of cerebral blood flow were observed before and after treatment. Results: There was significant difference in clinical efficacies between two groups (P<0.05). There were also significant differences in arterial blood flow velocities of before and after treatment. Acupuncture can produce substantial differences (P<0.05) in blood flow velocities of vertebral artery (VA), middle cerebral artery (MCA) and anterior cerebral artery (ACA) during an increased flow rate. It can also produce statistical differences in blood flow velocities of VA during a decreased flow rate (P<0.05). Conclusion: Acupuncture can effectively alleviate the pain of migraine sufferers and exert a two-way regulation on the cerebral blood flow.

Objective To obtain genes encoding the novel molecules for diagnosis of schistosomiasis. Methods The cDNA library of Schistosoma japonicum (Sj) schistosomula of day 15 post-infection was screened with positive patients sera,and the inserts of positive clones were sequenced. Then the sequences were compared with all sequences in GenBank database by Internet. The positive clones were analyzed by the software in bioinformatics. Results After three rounds of screening,15 positive clones were obtained,and among them 11 clones had the meaningful sequences,in which 5 genes coding for Sj mitochondrion,1 gene coding for Sj myosin and the others were SjCHGC05315,SjCHGC01371,SjCHGC04782,SjCHGC05166,SjCHGC09769,respectively. Conclusion Immunological screening by using positive patients sera can be used to discover Sj antigen genes with a potential value for diagnosis.

Tetraspanin 2-A(SjTsp2-A) gene was amplified by PCR.pcDNA3.1(+)/SjTsp2-A recombinant plasmids were constructed and transformed into E.coli DH5?.Twenty four BALB/c mice were randomly divided into pcDNA3.1(+) /SjTsp2-A group(A),pcDNA3.1(+)/SjGST group(B) and pcDNA3.1(+) group(C).Each mouse was injected through musculus quadriceps femoris by three times(two weeks interval) respectively with 100 ?g pcDNA3.1(+)/SjTsp2-A,pcDNA3.1(+)/SjGST,or pcDNA3.1(+).At two weeks after the final inoculation,mice were each challenged by 40?2 cercariae of S.japonicum.Forty-five days after infection,all mice were sacrificed,the number of worms collected and eggs in liver tisssue was counted.Anti-pcDNA3.1(+)/SjTsp2-A antibody was detected by ELISA and protein expression in quadriceps muscle by immunohistochemical staining.The worm reduction rate(44.4%) and egg reduction rate(28.4%) of group A was higher than those of group B and C(P

Objective: PCBP1 is a family member of heterogeneous nuclear ribonucleoproteins (hnRNPs) that belong to RNA-binding proteins and bear three KH domains. The protein plays a pivotal role in post-transcriptional regulation for RNA metabolism and RNA function in gene expression. We hy-pothesized and were going to identify that the regulatory function of PCBP1 is performed through different complexes of proteins that include PCBP1. Methods: To test our hypothesis, approaches of protein wal-king with a yeast two-hybrid system (Y2H), pulling down in yeasts, co-immunoprecipitation and immu-nofluorescent microscopy assay were employed in this study. The PCBP1 was used as the initial "walker" to search for its interaction partner(s). Results: Candidate proteins including MYL6, PECAM1, CSH1,RAB7, p57KIP2, ACTG1, RBMS1 and PSG4-1ike were identified with selection mediums and preceding methods. Conclusion: With these candidate protein molecules, some protein complexes associating with PCBP1 are proposed, which may help in a better understanding of physiological functions of PCBP1 and proved evidence that PCBP1 is involved in variant biological pathways.

Objective To screen permethrin human single-chain variable region (scFv) antibody for aims of developing rapid detection kit. Methods Phage display technology was used in this study. Permethrin was solid phase coated on Nunc plate as antigen. Semi-synthetic single-chain variable region of human antibody library technology was applied, and single chain variable region was screened from phage antibody library after 3 rounds "adsorption - elution - amplification" of the selection process. 100 clones were random selected as resistance to permethrin clones , enzyme-linked immunosorbent assay (ELISA), crossreactivity and competitive inhibition experiments were used to validate permethrin binding activity with strong scFv clones from the selected phage antibody clones plasmid. The plasmid was digested with restriction enzyme Sfi Ⅰ / Not Ⅰ and subcloned into pCANTAB5E vector. After transformed into E. coli XL1BIue, the plasmid was identified by restriction enzyme analysis. Results After screening in 100 clones, 18 clones had high ELISA absorbance values ( A value) at 490nm wavelength ( A490nm), then bovine serum albumin (BSA) cross-reactions identified five weak cross-reaction. Combined with the triplicate ELISA and competitive inhibition experiment results, one positive clone was acquired at last. And this clone was subcloned into pCANTAB5E vector and transformed into competent cells XL1-Blue. Conclusion Plasmid fragment was consistent with the purpose, which provided the foundation for further study of its specific affinity.

Those who took the tablet Finasteride orally were treated as the control group. Result The total effective rate was 94.6% in treating group, while that was 86.7% in the control group, P＞0.05. Conclusion It is suggested that electro-acupuncture plus Tuina has a certain effect on prostatic hypertrophy. Compared with western medicine, it is lower in price and has no side effect.

Gastric xanthoma, also known as gastric macular tumor or gastric lipid island, is a benign lesion that occurs in the gastric mucosa as a result of fatty deposits. Its etiology and pathogenesis are not yet clear, and may be related to gastric mucosal damage and repair, intestinal metaplasia, and abnormal lipid metabolism. Gastric xanthoma can be seen in any part of the stomach, usually in gastric antrum and pylorus region. Gastric xanthoma is reported to be associated with increased risk of early gastric cancer. This article reviewed the progress of research on correlation between gastric xanthoma and gastric cancer and precancerous lesions.
