Objective To discuss the efficacy and safety of decitabine plus aclacinomycin/cytarabine/ G-CSF (CAG) regimen in the treatment of patients with relapsed refractory acute myeloid leukemia (AML).Methods 17 cases with relapsed refractory AML were collected.They were given decitabine (25 mg/d,d1-5) plus CAG regimen (aclacinomycin 20 mg/d,d3-6; cytarabine 10 mg/m2,d3-9; G-CSF 400 μg/d,d0-9).Results After one course treatment by decitabine plus CAG regimen,10 patients (58.8 ％) achieved complete response (CR),1 patient (5.9 ％) achieved partial response (PR) and 6 patients (35.3 ％) displayed no response (NR),the overall response rate was 64.7 ％ (11/17).For karyotyping of chromosomal abnormalities,only 1 case (100 ％) in CR showed normal karyotype.8 cases (66.7 ％) in CR,1 case (8.3 ％) in PR showed medium karyotype.1 case (25.0 ％) in CR showed bad karyotype.Statistical analysis revealed that there were significant differences among different groups (P ＜ 0.05).Follow-up to January 31,2013,15 patients survived,2 patients died early.The median overall survival was 67 d (14-307 d),and the median relapse-free survival was 47 d (14-152 d).Conclusions The combined regimen of decitabine and CAG in the treatment of patients with relapsed refractory AML has a high response rate,little non-hematologic side effects and good tolerance.

Objective To investigate the effect of lipid soluble fraction in the radix of Salvia miltiorrhiza (FSM) on conditioned place preference (CPP) in mice induced by morphine and preliminarily identify the fraction in the radix of S. miltiorrhiza. MethodsMorphine or NS was sc injected every other day to induce the obvious CPP in mice for 6 d. Before 30 min of sc injecting morphine, mice were ip administered different doses of lipid soluble fraction in the radix of S. miltiorrhiza. RP-HPLC method was used to identify the major component in the lipid soluble fraction in the radix of S. miltiorrhiza. ResultsThe staying time in morphine-paired white compartment was significantly prolonged. After treatment with lipid soluble fraction in the radix of S. miltiorrhiza (40 mg/kg, ip), the staying time in morphine-paired white compartment was significantly shortened (P

Aim To investigate the effects of Aplysin on the inhibition of gastric cancer cell in vitro .Methods MTT assay was used to examine the inhibition of gastric cancer cell 1ine SGC-7901 by Aplysin in different concentrations and at different times.The morphologic changes and the apoptosis of SGC-7901 was observed by inverted microscope and Hematoxylin-Eosin(HE)staining.Reverse transcriptase polymerase chain reaction(RT-PCR)assay was used to detect the changes of COX-2 mRNA expressions.Results Aplysin could decrease the proliferation significantly in a dose-dependent manner in SGC-7901 cells.When treating SGC-7901 with Aplysin in concentration of 120, 240 mg·L~(-1) for 24 h, the growth of the cell was obviously inhibited observing by inverted microscope.Aiso, when treating with the same concentration for 18 h, its chromatin became crimpled and breakdown, as well as cell shrinkage and apoptotic bodies formation when using HE staining.The apoptotic rates(%)of SGC-7901 was(15.0±2.12)%, (18.4±2.3)%, respectively, which was significantly higher than(1.4±0.55)% that in control group(P <0.01).60、120、240 mg·L~(-1) Aplysin could not effectively inhibited the mRNA expressions of COX-2(P ＞0.05).Conclusions Aplysin can inhibit the proliferation and induces apoptosis of SGC-7901 cells.

?Pathological myopia are often complicated by a series of pathological changes in fundus including foveoschisis, which can lead to visual dysfunction when processing with retinal detachment, macular hole, epiretinal membrane and vitreoretinal traction diseases. According to the current knowledge, the main mechanism of foveoschisisi might be attributed to the impaired macular structure and function caused by a variety of traction on the retinal and retina poor condition. Surgical treatments have been reported to be effective in treating foveoschisis, however, the indications and surgical procedures are still controversial. ln this article, we reviewed the clinical features, diagnosis, treatment strategies and prognosis of pathological myopia foveoschisis.

Objective To discuss the feasibility, efficacy and complications of CT-guided 125I seed implantation for the treatment of lymph node metastasis nearby the iliac vessels.Methods The clinical data of twelve patients with para-iliac vessel lymph node metastasis, who had been treated with CT-guided 125I seed implantation, were retrospectively analyzed. A total of 12 lesions were detected; the diameter ≤6 cm was seen in seven lesions, and the diameter >6 cm was seen in five lesions. Using computer treatment planning system, the source distribution was calculated. Under CT guidance 125I seeds with the activity of 0.4-0.7 mci were implanted into the metastatic lymph nodes with a seed interval of 0.5-1.0 cm. CT scan was performed immediately after implantation to check the distribution of seeds as well as the possible complications. After the treatment, D90 (90%prescription dose received by target volume) was ≥75 Gy in 6 patients and <75 Gy in other 6 patients. Two months after the treatment CT reexamination was employed, and imaging evaluation was conducted according to WHO Response Evaluation Criteria in Solid Tumors. Results CT-guided 125I seed implantation was successfully accomplished in all 12 patients. Two months after the treatment, the evaluation of the therapeutic effect showed that complete remission (CR) was obtained in 0 patient, partial remission (PR) in 8 patients, stable disease in 3 patients and progress disease in one patient;and the total effect rate(CR+PR) was 66.7%. The local control rate was 91.7%. In eight patients the pain that was caused by metastatic lymph nodes was significantly relieved within 1-14 days after 125I implantation treatment. Before the treatment three patients had lower limb edema, and in two of them the lower limb edema was obviously relieved within 1-14 days after the treatment. All patients were followed up for 3-39 months, and the median follow-up time was 11 months. One-year survival rate was 41.7%. No severe complications such as massive hemorrhage, infection, myelosuppression or seed displacement occurred. Conclusion For the treatment of para-iliac vessel lymph node metastasis, CT-guided 125I seed implantation is safe and feasible. Better curative effect may be achieved when the diameter of the metastatic lymph node is<6 cm and the peripheral radiation dose is>75 Gy.

OBJECTIVETo investigate the protect effects of sodium ferulate (SF) on the daunormbicin(DNR-induced cardiotoxicity in juvenile rats.

METHODSForty male juvenile SD rats were randomly divided into control group (Control), daunorubicin group (DNR), sodium ferudate treatment group (DNR + SF), sodium ferudate group (SF) (n = 10) . Juvenile rats were intraperitoneally treated with DNR (2.5 mg/kg every week for a cumulative dose of 10 mg/kg) preparation immature myocardial injury model in presence with SF (60 mg/kg) oral treat- ment for 25 days. The left ventricular pressure and its response to isoproterenol were measured using left ventricular catheter. Rat myocardium myocardial pathology specimens and ultrastructure changes were also observed. The expression of cardiac Troponin I (cTNI) was detected by Western blot and RT-PCR. Results: SF treatment could inhibit the decreasing of heart rates induced by DNR damage (P < 0.05); it could increase the left ventrivular end diastolic pressure(LVEDP), heart rate, the maximal left ventrivular systolic speed(LVP + dp/dtmax) and the maximal left ventrivular diastolic speed (LVP-dp/dtmax) responding to isoproterenol stimulation(P < 0.01); SF also could improve the myocardial ultrastructure injuries and inhibit the decreasing of cTNI expression caused by DNR damages (P < 0.05).

CONCLUSIONSF treatment could alleviate the decreasing of cardiac reservation induced by DNR damages in juvenile rats, which might be related to its reversing the effects on the cardiac systolic and diastolic function injuries and its inhibiting effects on the decreasing of cTNI expression caused by DNR. The mechanism of SF preventing daunorubicin-induced cardiotoxicity in juvenile rats is relevant to inhabited cardiac Troponin I expression.
