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.

Ginseng, the root of Panax ginseng C. A. Mayer, has long been used clinically in China to treat various diseases. Multiple effects of ginseng, such as antitumor, antiinflammatory, antiallergic, antioxidative, antidiabetic and antihypertensive have been confirmed by modern medicine. Recently, the clinical utilization of ginseng to treat heart diseases has increased dramatically. The roles of ginseng in protecting heart are foci for research in modern medical science and have been partially demonstrated, and the mechanisms of protection against coronary artery disease, cardiac hypertrophy, heart failure, cardiac energy metabolism, cardiac contractility, and arrhythmia are being uncovered progressively. However, more studies are needed to elucidate the complex mechanisms by which ginseng protects heart. All such studies will provide evidence of ginseng's clinical application, international promotion, and new drug development.

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.

AIMTo investigate the preparation, shape and ultrasound triggered release characteristics of gelatin nanogel modified with fluoride anion.

METHODSAdriamycin gelatin nanogel modified with fluoride anion (ADM-FMNG) was prepared by co-precipitation with fluoride anion. The content and encapsulation rate of adriamycin were measured by HPLC method. The size and shape of ADM-FMNG were determined by electron microscope. The size and distribution of ADM-FDNG before and after sonication were measured by laser size analysis device.

RESULTSThe average diameter of ADM-FMNG was (46 +/- 12) nm. Adriamycin encapsulated rate and loading were 87.2% and 0.091 g x L(-1), respectively. 48.5% of adriamycin was released within 50 h while in vitro at 37 degrees C. Under the action of ultrasound that has the frequency of 20 kHz, 0.4 W x cm(-2) of power density and 7-8 min duration, 51. 5% of adriamycin in ADM-FMNG was released that was significantly higher than control group, the size of ADM-FMNG was changed from (46 +/- 12) nm to (1,212 +/- 35) nm and restored after ultrasound stopped for 3-4 min.

CONCLUSIONADM-FDNG system has the sensitive ultrasound triggered release characteristics.

To optimize the belt drying process conditions optimization of Gardeniae Fructus extract from Reduning injection by Box-Behnken design-response surface methodology, on the basis of single factor experiment, a three-factor and three-level Box-Behnken experimental design was employed to optimize the drying technology of Gardeniae Fructus extract from Reduning injection. With drying temperature, drying time, feeding speed as independent variables and the content of geniposide as dependent variable, the experimental data were fitted to a second order polynomial equation, establishing the mathematical relationship between the content of geniposide and respective variables. With the experimental data analyzed by Design-Expert 8. 0. 6, the optimal drying parameter was as follows: the drying temperature was 98.5 degrees C , the drying time was 89 min, the feeding speed was 99.8 r x min(-1). Three verification experiments were taked under this technology and the measured average content of geniposide was 564. 108 mg x g(-1), which was close to the model prediction: 563. 307 mg x g(-1). According to the verification test, the Gardeniae Fructus belt drying process is steady and feasible. So single factor experiments combined with response surface method (RSM) could be used to optimize the drying technology of Reduning injection Gardenia extract.

Seashore landfill aquifers are environments of special physicochemical conditions (high organic load and high salinity), and microbes in leachate-polluted aquifers play a significant role for intrinsic bioremediation. In order to characterize microbial diversity and look for clues on the relationship between microbial community structure and hydrochemistry, a culture-independent examination of a typical groundwater sample obtained from a seashore landfill was conducted by sequence analysis of 16S rDNA clone library. Two sets of universal 16S rDNA primers were used to amplify DNA extracted from the groundwater so that problems arising from primer efficiency and specificity could be reduced. Of 74 clones randomly selected from the libraries, 30 contained unique sequences whose analysis showed that the majority of them belonged to bacteria (95.9%), with Proteobacteria (63.5%) being the dominant division. One archaeal sequence and one eukaryotic sequence were found as well. Bacterial sequences belonging to the following phylogenic groups were identified: Bacteroidetes (20.3%), beta, gamma, delta and epsilon-subdivisions of Proteobacteria (47.3%, 9.5%, 5.4% and 1.3%, respectively), Firmicutes (1.4%), Actinobacteria (2.7%), Cyanobacteria (2.7%). The percentages of Proteobacteria and Bacteroides in seawater were greater than those in the groundwater from a non-seashore landfill, indicating a possible influence of seawater. Quite a few sequences had close relatives in marine or hypersaline environments. Many sequences showed affiliations with microbes involved in anaerobic fermentation. The remarkable abundance of sequences related to (per)chlorate-reducing bacteria (ClRB) in the groundwater was significant and worthy of further study.
