Objective To analyze the clinical characteristics ,diagnosis and treatment of acute leukemia complicating deep ve‐nous thrombosis(DVT) to deepen the cognition on this complication .Methods The clinical data of consecutive patients with acute leukemia were performed the retrospective analysis .The occurrence situation of deep venous thrombosis was investigated and the a‐broad related literatures were reviewed .Results A total of 116 cases of acute leukemia in our department from July 2011 to March 2014 were treated ,in which 85 cases were acute myeloid leukemia and 31 cases were acute lymphoblastic leukemia;5 cases devel‐oped DVT with the proportion of 4 .31% (5/116) .Of these cases ,3 cases were acute promyelocytic leukemia and 2 cases were acute lymphoblastic leukemia .Conclusion The occurrence rate of DVT in the patients with acute promyelocytic leukemia is relatively higher ,if the patients have the corresponding symptom ,timely diagnosis and treatment should be conducted .

To study the expression of matrix metalloproteinase-2 and -9 in human prostate cancer, matrix metalloproteinase-2 and -9 were immunohistochemically detected in tissues of prostate cancer and benign prostatic hyperplasia (BPH). Our results showed that matrix metalloproteinase-2 and -9 levels in prostate cancer were much higher than those in tissues of BPH, with the cancer invasion being positively correlated with the expression of the metalloproteinases. It is concluded that matrix metalloproteinase-2 and -9 are better molecular markers, which are of help in the diagnosis and prediction of prognosis of prostate cancer.

Objective:
To evaluate the cost-benefit and cost-effectiveness of current strategy for preventing mother-to-child transmission (PMTCT) of hepatitis B virus.
Methods:
A decision tree model with the Markov process was developed and simulated over the lifetime of a birth cohort in Zhejiang Province in 2016. The current PMTCT strategy was compared with universal vaccination and non-vaccination. Costs were assessed from social perspective. Benefits were the savings from reduced costs associated with disease and effectiveness were measured by quality-adjusted of life-years (QALY) gained. The net present value (NPV), cost-benefit ratio (BCR) and incremental cost-effectiveness ratio (ICER) were calculated. Univariate and Probabilistic Sensitivity Analyses (PSA) were performed to assess parameter uncertainties. The parameters of costs and utilities value of hepatitis B-related disease came from the results of the field survey, which were obtained by face-to-face questionnaire survey combined with inpatient medical records, including eight county and municipal hospitals in Jinhua, Jiaxing and Taizhou. A total of 626 outpatients and 523 inpatient patients were investigated. The annual total costs of infection was calculated by combining the costs of outpatient and inpatient.
Results:
The PMTCT strategy showed a net-gain as 38 323.78 CNY per person, with BCR as 21.10, which was higher than 36 357.80 CNY per person and 13.58 respectively of universal vaccination. Compared with universal vaccination, the PMTCT strategy would save 2 787.07 CNY per additional QALY gained for every person, indicating that PMTCT would be cost-saving. The most important parameters that could affect BCR and ICER were the vaccine coverage rate and costs of hepatitis B related diseases respectively. The PSA showed the PMTCT strategy was preferable as it would gain more QALY and save costs.
Conclusions
The PMTCT strategy appeared as highly cost-beneficial and highly cost-effective. High vaccination rate was a key factor of high economic value.
