This study was purposed to analyze the characteristics of morphology, immunology, cytogenetic and molecular biology of leukemia cells in 12 AML patients with Ph(+) and their correlation with survival of patients. 12 patients with Ph(+) AML were diagnosed according to diagnostic criteria of WHO and existence of t(9;22) (q34;q11) or t(9;22) abnormality, meanwhile no evidence of CML chronic phase was observed. The results showed that 8 out of 12 cases were confirmedly diagnosed to be AML by morphologic and immunophenotypic examination, 4 cases were diagnosed as myeloid and B lymphocytic mixed acute leukemia. The Ph chromosome was detected in 10 cases by chromosome analysis at the first time of diagnosis, and some of the cases had coexistence of complex chromosome and/or normal karyotype. BCR-ABL transcript was detected in all 12 cases, including 7 cases with b3a2, 1 case with b2a2, 1 case with b2a2 variants, 2 cases with e1a2 and 1 case with e18a2. The 12 cases all got complete remission after chemotherapy and/or gleevec treatment, out of them 3 cases received chemotherapy and gleevec treatment, but 2 cases died; 9 cases received allogeneic hematopoietic stem-cell transplantation (allo-HSCT), 1 case died from relapse, among them 1 case died from transplant complications. The median survival was 24 (8 - 80) months, the overall survival of 3 years was (51.4 ± 17.7)%. It is concluded that the Ph(+) AML is a acute myelogenous leukemia with poor prognosis, but long-term survival may be achieved with HSCT as quick as after complete remission from gleevec and chemotherapy treatment. Meanwhile, the detection of BCR-ABL gene and it variants may be give more opportunity for diagnose and treatment, which can be used as routine screening for newly diagnosed leukemia.

OBJECTIVETo study the clinical features and proper treatment of 38 elderly patients with early double primary cancers.

METHODSThirty-eight elderly patients with early double primary cancers treated from January 1980 to March 2003 were retrospectively reviewed for involved organs, treatment and prognosis.

RESULTSDigestive tract was the most frequently involved, followed by urogenital system and lung. Long-term results of endoscopic mucosal resection (EMR), operation and radiotherapy were superior to other methods. The prognosis of gastrointestinal carcinoma was better than that of prostate carcinoma and hematopoietic system. The operation rate decreased with increasing age. The 5-year survival rates of EMR, operation and radiotherapy were 85.7%, 71.1% and 75.0%, respectively. The medium survival time was 120 months in first cancer and 39 months in the second primary cancer. The 5-year survival rates of the first cancer and second primary cancer were 88.6% and 53.8%.

CONCLUSIONYearly follow-up for elderly patients with endoscopy, beta ultrasonic scan and X-ray contribute to finding of early double primary cancers. Operation is the best treatment of early double primary cancers. Endoscopic mucosal resection is especially suitable for old patients with digestive tract and bladder cancer.

In order to explore the serum levels and clinical significance of tumor necrosis factor alpha (TNF-α) and interferon gamma (IFN-γ) in patients with hemophagocytic syndrome (HPS). The clinical data of HPS patients in Capital Medical University Beijing Friendship Hospital from October 2008 to October 2010 were collected. The serum concentration of TNF-α and IFN-γ in HPS patients and 20 healthy controls was measured with enzyme-linked immunosorbent assay (ELISA). The correlations between the levels of TNF-α and primary disease were analyzed, the levels of hemoglobin, ferritin, triglyceride, NK cell activity and sCD25 were detected on the same day, the correlations between the concentrations of TNF-α and IFN-γ and these laboratory indicators were analyzed. The results indicated that the serum levels of TNF-α and IFN-γ in 30 cases of HPS was higher than that in control group (p < 0.05, p < 0.01); the difference of TNF-α concentration was statistically significant in rheumatism-related and tumor-related HPS groups(p = 0.04), the level of TNF-α in HPS patients showed negative correlation with hemoglobin. It is concluded that the high levels of TNF-α and IFN-γ in HPS patients may play certain roles in the pathogenesis and progress of HPS. These data indicated that the high level of TNF-α may be the main factor for anemia in patients with HPS.

In order to investigate the expression of serum sHLA-G in hemophagocytic syndrome (HPS) patients and to evaluate its clinical significance, the clinical data of HPS patients in Capital Medical University Beijing Friendship Hospital during the period from September 2008 to July 2010 were collected. They were divided into infection-associated HPS, tumor-associated HPS and rheumatological disease-associated HPS according to cause of diseases. The serum concentration of sHLA-G in HPS patients and 25 healthy controls was measured by enzyme-linked immunosorbent assay (ELISA), the correlations between sHLA-G level and laboratory indicators were analyzed. The results showed that the level of serum sHLA-G in HPS patients was significantly higher than that in healthy controls (p = 0.003), but the difference was not statistically significant between HPS groups of different causes (p = 0.233). The positive correlation of sHLA-G level in HPS patients with platelet count was found, but there was no positive correlation of their sHLA-G levels with WBC, Hb, Plt, ALT, AST, LDH, Alb, TBil, DBil, IBil, Cr, BUN, TG, fibrinogen and ferritin levels detected on same day. It is concluded that the the increase of serum sHLA-G levels in HPS patients may be caused by different factors such as infection, tumor, T cell activation and over-stimulation of several cytokines. sHLA-G can inhibit NK cell activity, resulting in formation of abnormal immune storm, and may be play a role in the pathogenesis of HPS.

BACKGROUND: MicroRNAs (MiRNA) are a novel class of non-coding RNAs involved in the regulation of gene expression post-transcriptionally by cleavage or translational repression of their specific target miRNAs. Numerous studies have demonstrated that circulating miRNAs are stable and abundant in blood and aberrantly expressed under pathological conditions, including cardiovascular diseases. The implications of circulating miRNAs in acute myocardial infarction have recently been recognized. This review will highlight the potential role of miRNA as a novel class of biomarkers in acute myocardial infarction. METHODS: This systemic review is based on our own work and other related reports. RESULTS: During diseases circulating miRNAs are derived from not only circulating blood cells but also other tissues affected by ongoing diseases. These disease-related miRNAs in the blood can serve as potential biomarkers. CONCLUSION: The circulating miRNAs can be used as novel biomarkers potentially offering more sensitive and specific tests than those currently available for diagnosis of acute myocardial infarction.

OBJECTIVETo observe clinical therapeutic effects of acupuncture for pattern of liver-stagnation and spleen-deficiency in diarrhea-predominant irritable bowel syndrome (D-IBS) and its impact on cell factors.

METHODSForty cases were selected and divided into an acupuncture group (21 cases) in which acupuncture was applied and a medicine group (19 cases) in which oral administration of dicetel and bifidobacterium lactobacillus triple viable capsules were applied. The symptom scores, level of Th1-type cytokine (IFN-gamma, IL-2) and Th2-type cytokine (IL-4, IL-10) and ratio of IFN-gamma to IL-4 were compared in two groups before and after treatment to analyze acupuncture effect.

RESULTSThe clinical symptoms were improved after one-week treatment in the acupuncture group (P<0.05), which had faster onset than the medicine group (P<0.05). The total effective rate was 90.48% (19/21) in the acupuncture group, which was superior to 78.95% (15/19) in the medicine group (P<0.05). Compared with medicine treatment, imbalanced condition of Th1/Th2 was turning towards the direction of Th2 after acupuncture, indicating a tendency to recover the balance.

CONCLUSIONThe clinical efficacy of acupuncture for D-IBS has close relationship with effectively improving balance of Th1/Th2 in patients with liver-stagnation and spleen-deficiency.
