Objective To evaluate the clinical outcome and relative factors of intervention treatment for atherosclerotic renal artery stenosis in elderly patients.Methods The clinical data of 79 patients diagnosed as atherosclerotic renal artery stenosis by angiography and treated by revascularization were analyzed.Results There were 55(69.6%)successes and 24(30.4%)failures in decreasing blood pressure and 28(35.4%)successes and 51(64.6%)failures in improving renal function after intervention treatment.Predictors of favorable outcome of intervention treatment in decreasing blood pressure were related to lower urine protein,higher glomerular filtration rate,higher systolic and diastolic blood pressure before treatment,lower resistance index(RI)of renal artery,and no complication of cerebral vascular diseases.Predictors of favorable outcome of intervention treatment in improving renal function were related with percentage of angiographic stenosis,category of antihypertension and lower urine protein.The logistic regression analysis showed that the percentage of angiographic stenosis was the most important predictor of intervention treatment for blood pressure control,age and level of serum creatinine before intervention treatment were the most important predictors of intervention treatment for improving renal faction.Conclusion Percentage of stenosis(≥85%),age(133 ?mol/L)can be used as the predictors of therapeutic success for renovascular stenosis in older patients.

Objective To evaluate the clinical value of transoesophageal echocardiography on perventricular closure of ventricular septal defects(VSD).Methods Transoesophageal echocardiography (TEE)was performed in 27 patients with VSD diagnosed by the transthoracic echocardiography examination (TTE)and prepared to receive perventricular closure of VSD for the purposes of choosing the appropriate occluder before VSD closure and guiding occluder release during the operation and evaluating the post operative effects of VSD closure 1 week post operation.Results Three patients with VSD not suitable for perventrieular VSD closure according to TEE results were not operated,perventricular closure of VSD were successfully performed in 20 patients and minimal residual shunt was seen in 1 patient post operation,perventricular closure of VSD failed in 4 patients and these patients received surgical closure.TEE at 1 week post successfully with perventricular closure of VSD in the 20 patients showed that there were no residual shunts and the pulmonary artery pressure was significantly lower post operation compared to that of preoperation value.Conclusion TEE is helpful in choosing the suitable patients and occlude size,guiding occlude release and evaluating the post operative results for perventricular closure of ventricular septal defects.

The aim of this study was to investigate the efficacy of different chemotherapy regimens in patients with multiple myeloma (MM). The therapeutic effects of 71 MM patients receiving standard chemotherapy regimens were retrospectively analyzed and evaluated. The results showed that 44 out of 71 new-diagnosed MM patients gained remission in varying degree, total effective rate was 61.9%, in which the rate of complete remission (CR) plus nearly complete remission (nCR) was 21.1%. 21 MM patients received M2 regimen gained total effective rate of 57.1%, in which the CR plus nCR were found in 5 MM patients, and partial remission (PR) was observed in 7 MM patients. 8 MM patients received MP chemotherapy regimen gained total effective rate of 37.5%, in which the CR + nCR was not found, but the PR was observed in 3 MM patients. 30 MM patients received VAD regimen gained total effective rate of 63.3%, in which CR + nCR and PR were found in 6 and 13 MM patients respectively, 12 MM patients received combined bortezomib regimen gained total effective rate of 83.3%, in which CR + nCR and PR were found in 4 and 6 MM patients respectively. The median time of progression and the median time of survival in 72 MM patients were 22.1 and 29.5 months respectively. The 3 and 5 year survival rates in 72 MM patients were 41.2% and 20.6% respectively. In conclusion, the chemotherapy regimen for new-diagnosed MM patients should be selected according to their clinical features and subtypes, the bortezomib-combined regimen may be considered as a new and effective regimen for MM patients.

OBJECTIVETo identify the abnormal karyotypes by fluorescence in situ hybridization (FISH) and explore prognostic implications in patients with myelodysplastic syndromes (MDS).

METHODSFISH was used to detect the frequently occurring chromosome abnormalities (-5/5q, +8, -7/7q-) in 37 MDS cases. SPSS 11.5 software and correlation analysis were used to analyze the relativity among the abnormal chromosomes, the prognosis and the disease conversion in 37 MDS patients.

RESULTSKaryotype abnormalities were found in 21 (56.8%) of 37 cases, among which 6 (16.2%) were complex karyotypes, 9 (24.3%) +8, 2(5.4%) -5/5q-, 2(5.4%) -7/7q-. In the median time of follow-up of 12 months, 12 cases transformed into acute leukemia. Complex karyotypes were significantly associated with the poor prognosis and leukemia transformation. + 8 and -7/7q- abnormalities were correlated with the death.

CONCLUSIONSFISH was more sensitive than conventional cytogenetics for detecting mini-clonal abnormality. There are some differences in abnormal karyotypes between patients in China and the western countries. Multi-probes used in cytogenetic detections may predict the patient' s prognosis more accurately. The higher proportion of abnormal karyotypes the poorer prognosis.

OBJECTIVETo construct eukaryotic expression vector of the truncated septin2 and investigate the influence on the cultured mouse epidermal cell and fibroblast in vitro exerted by the transgenic expression product.

METHODSThe short splicing fragment was obtained by amplifying the reverse transcription product of the fetal mouse skin mRNA with PCR. Then its recombinant expression vector pcDNA3.1 (-)/septin2s was constructed and used to transfect the mouse epidermal cell and fibroblast cultured in vitro. The expression of the foreign gene was detected with RT-PCR and the changes of cell proliferation were observed and analysed.

RESULTSRT-PCR results indicated that pcDNA3.1/septin2 was expressed in the cultured mouse epidermal cells and fibroblasts in vitro. We found that the epidermal cells accelerated their reproduction, but the fibroblasts had no obvious changes.

CONCLUSIONWe successfully constructed eukaryotic expressive vectors of pcDNA3.1/ septin2s and transfected it into mouse epidermal cells and fibroblasts in vitro. The results settle a basis for showing effect of septin2s on fetal mouse skin.

OBJECTIVETo compare the difference of therapeutic effects between vessel pricking therapy and Prednisone for treatment of Henoch-Schonlein purpura nephritis.

METHODSSeventy cases of acute purpura nephritis syndrome were randomly divided into an observation group (40 cases) and a control group (30 cases). Patients in observation group were differentiated into sthenia and asthenia syndromes. Vessel pricking therapy was applied at Hegu (LI 4), Quchi (LI 11), Xuehai (SP 10) etc. by triangular needle for sthenia symptom; shallow needling was used at Pishu (BL 20), Shenshu (BL 23), Zusanli (ST 36) etc. by filiform needle. The control group was treated with oral admi-nidtration of Prednisone. The symptom score of TCM, 24 h urinary protein, red blood cell count of urinary sediment of both groups were observed before and after treatment and therapeutic effects were compared.

RESULTSThe total effective rate of 92.5% (37/40) in observation group was superior to that of 80.0% (24/30) in control group, and there was a significant difference between two groups (P < 0.05); the symptom score of TCM, 24 h urinary protein, red blood cell count of urinary sediment were all improved in both groups after treatment (all P < 0.05), and moreover, the improvement in observation group was superior to that of control group (all P < 0.05); after treatment, the symptom score of TCM of sthenia syndrome was lower than that of asthenia syndrome in observation group (P < 0.05).

CONCLUSIONVessel pricking therapy has a significant therapeutic effect for treatment of Henoch-Schonlein purpura nephritis, superior to that of oral administration of Prednisone, and the therapeutic effect is better for treating sthenia syndrome than for asthenia syndrome.
