Objective To explore the clinical characteristics,therapy reactions and prognosis of the elderly patients with idiopathic thrombocytopenic purpura(ITP). Methods A total of 43elderly ITP patients(age≥60 years old)including 16 men and 27 women were reviewed and further followed up for 1 month to 15 years. Results Until June 2007,35 elderly ITP patients survived,platelet counts were sustained(30-50)×109/L in 7 cases,but no significant bleeding was found.Thirty-six patients had adrenocorticosteroid therapy first, 25 patients were sensitive to adrenocorticosteroid therapy,4 patients underwent splenectomy,and 3 patients achieved a normal platelet count. Immunosuppressive agents(vinscristine,cyclophosphamide, azathioprine and Cyclosporin A)treatments were held in 5 6 case-times,Cyclosporin A and azathioprine were more effective than vinscristine and cyclophosphamide.The refractory rate was 13.9%.One patient progressed to monoclonal gammopathy of unknown significance and 1 to lymphoma.Eight patients died.1 patient died of brain bleeding after trauma,3 patients died of malignant neoplasm,4 patients died of heart failure induced by infection. Conclusions The clinical features of elderly ITP patients are atypical.the mortal bleeding in them was rare,treatment strategy should be individualized tO each elderly patient.

Objective To investigate the prevalence by age,response to different therapies and outcome in newly diagnosed idiopathic thrombocytopenic purpura(ITP). Methods ITP patients who were hospitalized from July 1992 to December 2006 and followed uD with telephone were retrospectively analyzed.Results 103 patients with ITP were investigated. The time of follow-up was between 2 months to 15years.to adrenocorticosteroid and 4 patients under going splenectomy achieved a normal platelet count. In those immunosuppressive agents:including vincristine,cyclophosphamide,azathioprine and cyclosporin A(CsA)used in the present series. CsA was shown to be more effective. It could increase the platelet count when given together with prednisolone,the effective rate was 81.3%(26/32). Severe side effects like kiney function failure were not found in CsA treated patients so the use of geug in ITP would be recommended.There were 2,1 and 1 ITP patients progressing respectively to Sjogren's syndrome,systemic lupus erythematosus and lymphoma. 7 patients died,1 patient died of cerebral bleeding,2 brain infarction,3 malignant neoplasm and 1 nephrosis The refractory rate of ITP is 17.2%(10/58). Conclusions The morbidity in older people is high. The mortal bleeding in ITP is low. Treatment should be tailored to the individual patient.

Objective To explore the clinical and biological characteristics and treatment effect of acute myeloid leukemia (AML) in elderly patients. Methods The clinical data of 62 patients over 60 years old with AML were retrospectively analyzed, and they were compared with those of 60 younger adult patients (18-59 years old) at the same period. Results In elderly patients, the complete remission (CR) rate was 27. 7% and the overall effective rate was 44.7%, which were lower than those of younger adult patients (74.1% and 87.9 %, 1-espectively, P＜0.01). The early death rate was 19.0% and the mortality rate during the first two induction chemotherapy was 29. 3% in the elderly, which were higher than those of younger adult patients (3. 3% and 6.7%, 1-espectively,P＜0.01). The 27.4% of elderly patients were diagnosed as myelodysplastic syndrome (MDS)-transformed AML, which were more than that of younger adult patients (10.0%, P＜0.05), and they had lower CR rate than those without MDS (P＜0. 05). The 28.2% of elderly patients had lymphoid antigen positive AML and 71.8% of patients showed CD34+ which were higher than those of younger adult patients (8. 1% and 48.6%, respectively, P＜0. 05), and they had lower CR rate than those of lymphoid antigen negative and those of CD34- AML (P＜0. 05). Elderly patients had less favorable and more unfavorable karyotypes than younger adult patients (45.7 % and 15.4 %, P＜0. 05). Conclusions The elderly patients with AML have more unfavorable prognostic factors than younger adult patients. They have lower CR rate and higher mortality rate. There are many specialties in elderly patients and the treatment strategy should be made more individually.

Objective To explore the impact factors for post-thaw embryo survival rate and clinical pregnancy rate in frozen-thawed embryo transfer program. Methods The clinical data of 573 cycles of frozen-thawed embryo transfers were retrospectively analysed. Groups were divided according to the pre-freeze embryo quality, pre-freeze embryonic developmental stage, frozen-thawed embryo quality and cryopreservation technique, respectively, and post-thaw embryo survival rates and/or clinical pregnancy rates were compared among groups. Results The clinical pregnancy rate of high quality pre-freeze embryo was significantly higher than that of low quality pre-freeze embryo (31.8% vs 20.0%) (P< 0.05). There was no significant difference in the post-thaw survival rates and clinical pregnancy rates between embryos frozen at day 2 of ferrtilization and those frozen at day 3 of ferrtilization(79. 1% vs 82.9% and 25.5% vs 31.2%, respectively) (P>0.05). The clinical pregnancy rates of the transfer cycles only with fully intact embryos and with mixed embryos were significantly higher than that only with partially damaged embryos(36.7% vs 24.1% and 29.2% vs 24.1%, respectively)(P<0.05). The post-thaw survival rate and post-thaw high-quality embryo rate were significantly higher in those processed with modified cryopreservation technique than in those processed with original cryopreservation technique (82.0% vs 66.3% and 50.0% vs 27.5%, respectively)(P<0.05). Conclusion Pre-freeze embryo quality, post-thaw embryo survival rate and post-thaw embryo quality have a positive correlation to subsequent clinical pregnancy rate. Favorable cryopreservation technique may ensure the success of post-thaw embryo recovery and transfer.

OBJECTIVETo observe the effect of 1,25(OH)2D3 on thyroid inflammation and Th1/Th2 cells in rats with experimental autoimmune thyroiditis (EAT).

METHODSForty-eight female Wistar rats were randomly divided into 4 groups, namely the prevention group treated with 1, 25-(OH)2D3 from 0 to the 6th week (n=10), treatment group with 1,25(OH)2D3 treatment from the 2nd to the 8th week (n=10) after immune sensitization, positive control group (n=12) and the negative control group (n=16). All the rats were challenged with porcine thyroglobulin for immune sensitization until the 6th or 8th week except for those in the negative control group. In the prevention group and treatment group, the rats received 1,25(OH)2D3 at 5 microg/kg by intraperitoneal injection every other day, while those in the positive and negative control groups were given peanut oil instead. The thyroid pathologies, serum autoantibody level and cytokine levels were examined after the treatments.

RESULTSThe thyroid gland remained structurally intact in the negative control group. In the positive control group, the thyroid showed obvious inflammatory change with structural disruption and even disappearance of the thyroid follicle. The structure of the thyroid gland follicles was intact in the prevention group and treatment group. No significant differences were found in the autoantibody and cytokine levels between the prevention group and negative control group (P>0.05). Compared with the positive control groups, the autoantibody and IFN-gamma and IL-12 levels decreased significantly in the treatment group, but the levels of IL-4 and IL-10 were markedly increased (P<0.05).

CONCLUSION1,25(OH)2D3 given before the establishment of the EAT model helps maintain structural integrity of the thyroid gland and normal levels of the antibodies and cytokines in rats. 1,25(OH)2D3 can ameliorate the pathological changes of the thyroid gland and correct the cytokine disequilibrium in rats with EAT.

OBJECTIVETo investigate PHEX gene mutations in 2 patients with X-linked hypophosphatemic rickets (XLH) and their families and to clarify the genetic etiology.

METHODSA retrospective analysis was performed for the clinical data of two patients with XLH. High-throughput sequencing was used to detect the PHEX gene, a pathogenic gene of XLH. PCR-Sanger sequencing was used to verify the distribution of mutations in families.

RESULTSBoth patients had novel mutations in the PHEX gene; one patient had a frameshift mutation, c.931dupC, which caused early termination of translation and produced the truncated protein p.Gln311Profs*13; the other patient had a splice site mutation, IVS14+1G>A, which caused the skipping of exon 15 and produced an incomplete amino acid chain. Their parents had normal gene phenotypes.

CONCLUSIONSc.931dupC and IVS14+1G>A are two novel mutations of the PHEX gene and might be the new pathogenic mutations of XLH.
