OBJECTIVETo compare the difference in the clinical efficacy on premature ovarian failure (POF) between the acupoint catgut implantation combined with artifical periodic therapy and the simple artificial periodic therapy and explore its effect mechanism.

METHODSSixty-five patients of POF were randomized into the two groups. In a western medication group, 32 cases were treated with the artificial periodic therapy with the oral administration of medroxyprogesterone acetate tablets. In a catgut implantation + western medication group, 33 cases were treated with the acupoint catgut implantation combined with artificial periodic therapy. The acupoints of Neiguan (PC 6), Zusanli (ST 36), Guanyuan (CV 4) and Sanyinjiao (SP 6) were selected. The treatment was lasted for half a year and the follow-up visit was for another half a year in the two groups. Kupperman index was used to assess the improvements in the clinical symptoms. The levels of serum sexual hormones such as follicle stimulating hormone (FSH) and estradiol (E2) were evaluated of the patients in the two groups before and after treatment. The efficacy was compared between the two groups.

RESULTSThe scores of the clinical symptoms were all significantly improved after treatment and in the follow-up in the two groups (P < 0.01, P < 0.05). In the 6-month follow-up visit after treatment, the result in the catgut implantation + western medication group was better than that in the western medication group (8.17 +/- 1.19 vs 13.68 +/- 1.08, P < 0.01). FSH was reduced after treatment in the two groups (all P < 0.01) and E2 was increased (all P < 0.05). The curative and remarkably effective rates were 75.8% (25/33) and 81.8% (27/22) after treatment and in the follow-up visit in the catgut implantation + western medication group, which were better than 67.9% (19/28) and 53.6% (15/28) in the western medication group separately (P < 0.05, P < 0.01).

CONCLUSIONThe acupoint catgut implantation combined with artificial periodic therapy achieve the remarkable improvements in the clinical symptoms of POF in the patients and the better results as compared with the simple western medication therapy. The combined therapys efficacy is stable and the long-term efficacy is apparently superior. The effect mechanism is related to the improvements in the serum sexual hormone levels.

OBJECTIVETo investigate the relation of heparanase gene and angiogenesis with the progress of gastric carcinoma (GC).

METHODSExpression of heparanase mRNA in 52 GC tissue was detected by in situ hybridization assay. Microvessel density (MVD) was examined by immunohistochemical method. MVD and heparanase mRNA expression were analysed with their relation to histological grade, invasion depth,lymph node metastasis and organ metastasis.

RESULTSMVD was 73.2 +/- 22.8 in 25 (48.1%) tissue with positive heparanase mRNA. It was 44.8 +/- 11.9 in 27 (51.9%) tissues with negative heparanase mRNA, between which the difference was significant (P < 0.001). MVD and heparanase mRNA expression were related with lymph node metastasis and depth of serosal invasion in GC (P < 0.005).

CONCLUSIONHeparanase, being related to angiogenesis in gastric cancer, promotes growth, invasion and metastasis. Heparanase mRNA expression is an important predictor of the biological behavior of human gastric carcinoma.

OBJECTIVETo study the immunophenotype and its relationship with clinical characteristics in children with acute lymphoblastic leukemia (ALL).

METHODSBone marrow or blood samples (2-3 mL) with heparin anticoagulation from 139 children with ALL were obtained, and immunophenotypes were identified by flow cytometry.

RESULTSIn 139 ALL children, there were 103 cases (74.1%) of B-ALL, 24 cases (17.3%) of T-ALL, 12 cases of T/B biphenotypic (8.6% of T/BALL). In the 103 children with B-ALL, CD19 (90.3%), CD10 (83.5%) and CD20 (27.2%) were expressed as major antigens. In the 24 children with T-ALL, the major antigens were CD3 (79.2%), CD7 (66.7%) and CD5 (33.3%). In the 12 children with B/T-ALL, T-lymphoid antigens included CD7 (50.0%) and CD5 (41.7%), while the B-lymphoid antigens included CD19 (50.0%) and CD10 (33.3%). Of the 139 children with ALL, 32 cases (23.0%) showed myeloid antigen expression (My+ ALL) and the main expression antigens were CD13, CD33, CD14 and MPO. CD34 was expressed in 31 cases. CD34-positive expression (15.6%) in My+ ALL children was significantly lower than in My-ALL children (24.3%). HLA-DR was expressed in 82 of the 139 ALL children. The expression of CD10, CD34 and HLA-DR in the standard-risk, medium risk, high-risk ALL children was significantly different. There were significant differences in gender and incidence of bleeding between the My+ ALL and My-ALL groups (P<0.05).

CONCLUSIONSImmunetyping can differentiate the sources of leukemic cells. The expression of CD10, CD34 and HLA-DR antigen is related to the clinical classification of ALL.

Objective To clone and sequence the cysteine protease inhibitor gene of periodic Brugia malayi(BmCPI) and predict B-cell epitopes in amino acide sequence of BmCPI in order to provide basis for further study the expression of BmCPI and its function. Methods Total RNA was extracted from periodic Brugia malayi.A couple of specific primers were designed on the basis of known sequences of cysteine protease inhibitor gene from BmCPI. The desired gene was amplified by PCR technique from cDNA. The PCR products were purified and cloned into plasmid pGEM-T by T-A cloning method, transformed into Escherichia coli(E, coli) strain DH5α. The recombinant plasmids were screened and identified by digestion with restriction enzyme and PCR amplification. Five parameters and methods were used to predict B-cell epitopes in amino acide sequence of BmCPI. Results For RT-PCR, a specific band of around 621 bp was amplified. The same band was obtained by double restriction of recombinant plasmids or PCR using recombinant plasmid as template. The result of DNA sequencing showed that BmCPI shares 99% nucleotide sequence identity with that of published sequence. It showed that B-cell epitopes were probably at or adjacent to 23 - 32, 50 - 79 and 117 - 126 in its amino acide sequence. Conclusions pGEM-BmCPI is successfully constructed and sequenced, anticipated objective is reached and conditions is provided for further study of BmCPI expression and its function.
