Tissue samples from 42 patients with nonepitheliogenie ovarian tumors were assayed for estrogen receptor (ER) and progesterone receptor (PR) by Lce's fluorescent histochemical method. 2 of 4 theca cell tumor, 6 of 8 granulosa cell tumor had ER and PR. Among the 6 cases of granulosa cell tumor, 4 cases exhibited a high level of receptors (ER、PR positsve cell: 40%～50% of total tumor cells). As to teratomas, the epithelial cells of sweat glands, and cylindrical epithelia, as well as chondrocytes were ER PR positive. No ER-and PR-positive cells were found in endodermal sinus tumors, drsgerminomas and fibromas. Of 4 mataststic ovarian tumors, which were from gastrointestinal adenocarcinoma, tbe ER-and PR-positive cells were found in 1 specimen. The findings suggested that hormone-related therapy might be worthy of trying on thc patients with receptor positive granulosa cell tumor.

Objective To investigate the expression of monocyte chemoattractant protein-1(MCP-1)and CCR2 in peripheral blood and pleural fluid of tuberculous pleurisy patients.Methods Flow cytometry was used to detect the expression of CCR2 in the peripheral blood mononuclear cell and pleural fluid cell of tuberculous pleurisy patients;ELISA was used to detect the content of MCP-1 in serum and pleural fluid.Results MCP-1 in surem and pleural fluid and CCR2 in the peripheral blood mononuclear cell and pleural fluid cell of tuberculous pleurisy patients was significantly higher than that of the healthy normal controls[MCP-1:(340.8±220.8)and(9.0±3.8)ng/L,P＜0.01;CCR2(18.2±10.1)%and(6.9±3.5)%,P＜0.05];Both MCP-1 and CCR2 were detected in pleural fluid and both of them were positivley correlated(r=0.227,P＜0.05).Conclusion The expression of MCP-1 and CCR2 in peripheral blood of tuberculous pleurisy patient are significantly elevated which are significance molecule participating in the pathogenesis of tuberculous pleurisy.

[Summary] Interleukin-2 receptor antagonist (IL-2Ra,ie,basiliximab and daclizumab),a new antibody agent,is widely employed in lowering the risk of acute rejection after organ transplantation,but it meanwhile causes increasing concerns on the effect it exerts on glucose metabolism in transplant recipients,and so far the exact effect still remains controversial.New onset diabetes after transplantation (NODAT) is one of the most influential metabolic complications affecting graft survival and patients' long-term outcomes.Some of the current researches indicate that IL2Ra may improve glucose metabolism in the transplant recipients,some show just the opposite,yet others show no effects.Hence further investigations focusing this aspect are needed.

OBJECTIVEMinimal deviation adenocarcinoma (MDA) is frequently underdiagnosed in pathology tests due to its benign histopathological features. Therefore, its clinical and pathological characters need to be further analyzed and to establish useful immunohistochemical markers to improve the accuracy of pathological diagnosis.

METHODSClinical pathology data were of 13 MDA cases collected and analyzed in the First and Second Hospitals attached to the University, the pathological characters were compared with matched benign hyperplastic and atypical hyperplastic controls of the glandular epithelial cells to find histochemical and immunohistochemical indices valuable for the pathological diagnosis. 8 of these 13 cases were followed and their conditions were discussed.

RESULTSThe main clinical symptoms were watery leucorrhagia, enlargement of the cervix with erosion and hardening. Thickened ligaments were also detected in some cases. The pathological findings included hyperplasia and mild abnormality of the glands, invasion effects into the stroma could be observed in some glands and abortive glands with desmoplastic changes, or edema and inflammatory infiltration around the glands were also observed. The invasion presented in the deep part of the cervix as well, some were found near larger blood vessels or in the small vessels. Compared with benign glands, the immunohistochemical indices of most MDA glands were demonstrated as cancer embryo antigen (CEA) + + +, Ki-67 +--+ + +, P53 +--+ + +, AB/PAS +/+ +, and focal defect on the basement membrane.

CONCLUSIONSOnce any of the diagnostic characters summarized as above was determined, the probability of MDA should be seriously considered, at least atypical hyperplasia in cervical glands must be diagnosed, and follow-up on the patients and histological biopsy of deep tissues (> 5 mm) of the cervix will be necessary to determine the inclusion/exclusion of MDA. Obviously, a correct pathological diagnosis is extremely important for the patient to receive proper treatment in time and thereby improve her quality of life.

Objective:To establish the technique for real-time fluorescence quantitative reverse transcription polymerase chain reaction(FQ-PCR)by DNA melting curve analysis for detecting the CDR3 shewing of TCR alpha gene repertoire in human peripheral blood.Methods:Total RNA of peripheral blood mononuclear cell(PBMC)from 4 healthy donors and 2 patients with lymphomatous leukemia were transcripted reversely into cDNA.The cDNA of 32 TRAV gene family CDR3 was amplified by FQ-PCR.Analysis of the monoclonal/oligoclonal/polyclonal CDR3 spectratyping with DNA melting curve.Results:The FQ-PCR products of 32 TRAV family CDR3 were showedas a blur land at the predicted of products size in healthy donors and parts of TRAV family CDR3 products disappeared in patients on 1.5% agarose gel by Gold-View staining.The 32 TRAV family CDR3 were showed with different frequencies by relative fluorescence quantitative in healthy donors and the patients.The CDR3 spetratyping for 32 TRAV families was showed as polyclonal peak(Gaussian distribution)in healthy donors but showed as different monoclonal/oligoclonal/polyclonal peak in the patients with lymphomatous leukemia with DNA melting curve analysis(we called "melting curve spectratyping of CDR3")Conclusion:The study suggests that the technique of "FQ-PCR with DNA melting curve analysis be convenience and celerity for detecting the CDR3 skewing of TCR alpha gene repertoire in human peripheral blood.

Objective To explore the association between HLA-A*31, B*40, B*58 and DRB1*16 allele polymorphisms and onset of hemorrhagic fever with renal syndrome (HFRS) in Zunyi Han population. Methods Using group study, HLA-A*31, B*40, B*58 and DRB1*16 genotyping was conducted in 100 HFRS cases and 100 controls among Han population in Zunyi area with polymerase chain reactionsequence specific primer(PCR-SSP), gene frequency (GF) and relative risk (RR) were calculated and compared. Results The results showed that the frequencies of A*3101, B*5801 and DRB1*1602 were increased in patients as compared to the healthy controls ( RR = 13. 825, x2 = 4. 296, P = 0. 038; RR =2.614,x2 =6. 133,P=0.013;RR =8.523,x2 =8. 865,P=0. 003). The frequency of B*4001 in patients with HFRS were significantly lower than that in the healthy controls( RR =0.414,x2 =6.640,P =0. 010).Conclusion These results suggest that HLA-A*3101, B*5801 and DRB1*1602 haplotypes were strongly associated with susceptibility to HFRS disease in Zunyi Han population and allele HLA-B*4001 might be associated with protection against hantaviruses infection.
