The macroporous resin separation technology has been mainly applied in the enrichment of saponins, flavonoids, alkaloids and other ingredients, and used in the removal of heavy metal impurities and pesticide residues in recent years. This paper focuses on the synthesis of the new-type macroporous adsorption resin LKS-11 according to the molecular structure characteristics of procymidone. Specifically, the selective absorptive property and other advantages of macroporous resin were utilized to analyze the procymidone removal efficiency in ginseng extracts from different sources. The type of macroporous resins, absorptive property and desorption conditions were observed respectively by static and dynamic adsorption methods to determined the optimum process conditions. According to the results, LKS-11 showed a good absorptive property to procymidone in ginseng extracts and provided a theoretical basis for studies on the removal of procymidone residues from ginseng extracts by using macroporous adsorption resin. Because of no secondary pollution on samples, low production and operation costs, high procymidone removal efficiency and high product recovery rate, this method is suitable to be applied in production.

OBJECTIVE:To observe the efficacy and safety of spraying mannatide and 5-fluorouracil in anocelia during sur-gery of lung cancer based on the adjuvant chemotherapy. METHODS:Totally 114 patients with lung cancer radical surgery were randomly divided into observation group(59 cases)and control group(55 cases). There were spraying mannatide(40-80 mg)and 5-fluorouracil(500 mg)in the observation group;and nothing drugs were sprayed in control group. The patients higher than phaseⅡ were treated by adjuvant chemotherapy after surgery for continuous 2 cycles,21 d as a cycle. The clinical data was compared, including amount of bleeding and drainage,hospital stay,complications,toxicity,KPS score,body weight changes,immune func-tion,survival rate and recurrence rates between 2 groups. RESULTS:There were no significant differences among the amount of bleeding and drainage,hospital stay and complications in the 2 groups (P>0.05). The nausea,vomiting,leucopenia,the KPS score,improvement of total effective rate,and improvement rate of body mass,immune function,survival rate in 1 and 2 year (s),recurrence rate and time within 2 years in observation group were significantly better than control group,with significant dif-ferences(P<0.01 or P<0.05). CONCLUSIONS:Spraying mannatide and 5-fluorouracil can reduce the toxicity in anocelia during surgery of lung cancer based on the adjuvant chemotherapy,improve the immune function and survival rate,reduce recurrence rate and prolong the recurrence time.

The aim of this study was to investigate the effect of Bu-Shen-An-Tai recipe (BSATR) and its two components (Bushen recipe, and Huoxue recipe) on endometrial morphology during peri-implantation in superovulated mice. Mice were randomly divided into five groups, including the normal (N), model (M), Bushen (BS), Huoxue (HX) and Bu-Shen-An-Tai (BH) groups. The uteri were collected on day 4 of pregnancy, and the endometrium thickness, microvessel density (MVD) and number of pinopodes observed. Compared with the M group, the endometrial thickness in the BS, HX and BH groups was significantly increased and there was a significant difference in endometrial thickness between the BS and the BH groups. The mean MVD was significantly lower in the M group than in the N group, and there was a significant increase in MVD in the BS, HX and BH groups as compared with the M group. Compared with the M group, the pinopode scores in the endometrium were significantly increased in the HX and BH groups; and the BS group had significantly higher pinipode scores than the HX and BH groups. In conclusion, the results of the present study demonstrated that the recipes (Bushen, Huoxue and BSATR) could improve the endometrial environment by regulating the endometrial thickness, MVD and the number of pinopodes at the window of implantation. Moreover, the Huoxue recipe and the BSATR were more efficient than the Bushen recipe, with the BSATR tending to have the most beneficial effects.

OBJECTIVETo explore the effects of beta-elemene combined with aclarubicin on the induction of HL-60 cell apoptosis and its mechanisms in antileukemia therapy.

METHODSHL-60 cells were treated for 20 hours with different dose of aclarubicin (0.05, 0.10, 0.25 microg/ml) or with different concentrations of beta-elemene (10, 20, 40 microg/ml) in the presence or absence of aclarubicin (0.10 microg/m). The apoptotic rate was analyzed by flow cytometry (FCM), the productions of PGE2 in culture supernatants was detected by competitive ELISA and the expressions of COX-2 and NF-kappaB activity in HL-60 cells by Western blot.

RESULTSLower concentration of aclarubicin (0.05, 0.10 microg/ml) didn't affect apoptotic rate, and COX-2, NF-kappa B and PGE2 expression on HL-60 cells. Combined treatment of beta-elemene and aclarubicin (0.10 microg/ml) enhanced the apoptotic effect and down-regulated COX-2, NF-kappaB and PGE2 expressions. There was a positive correlation between the effects and beta-elemene concentrations.

CONCLUSIONbeta-elemene enhances aclarubicin-mediated apoptotic effect, down-regulation of COX-2 and their inducing products PGE2 in HL-60 cells by suppressing activitation of NF-kappaB.

OBJECTIVETo investigate the clinical effect of chronic myelocytic leukemia (CML) patients treated with imatinib (IM) and interferon (IFN)-α.

METHODSOne hundred and fifty five CML patients at chronic phase were included in the study. All patients were divided into two groups according to treatment regimen: IM + IFN group and IM group. Complete cytogenetic response (CCyR) rate, major molecular response (MMR) rate, complete molecular response (CMR) rate, overall survival (OS) and progression free survival (PFS) were observed and compared in both groups.

RESULTSThe CCyR rate was higher in the IM + IFN group than that in the IM group at 6 months (60.6% vs 41.6%, P < 0.05), but no difference was observed later on. The MMR + CMR rate was higher in the IM + IFN group than that in the IM group at 6 months and 12 months (71.2% vs 34.8%, 77.3% vs 52.8%, respectively, P < 0.05), but no difference after that. After stratification according to Sokal risk, the CCyR rate of low- and intermediate-risk patients was higher in the IM + IFN group than that in the IM group at 6 months (77.8% vs 52.6%, 75.0% vs 46.7%, P < 0.05), but not from 12 months on; the MMR + CMR rate of low- and intermediate-risk patients was higher in the IM + IFN group than that in the IM group at 6 months and 12 months (85.2% vs 36.8%, 90.0% vs 36.7%, P < 0.05; 88.9% vs 57.9%, 90.0% vs 56.7%, P < 0.05), but not from 24 months on. There was no significant difference in high-risk patients. OS in IM and IM + IFN group at 6, 12, 24 and 36 months was 100%, 100%, 96.8% and 90.0%, and 100%, 100%, 97.9% and 93.1%, respectively. PFS in IM and IM + IFN group at 6, 12, 24 and 36 months was 97.8%, 95.5%, 91.9% and 85.5%, and 98.5%, 95.5%, 91.5% and 86.2%, respectively. There was no significant difference in OS (u = 0.427, P = 0.514) or PFS (u = 0.556, P = 0.456). The side effects in both groups included pancytopenia, edema, weight gain, ostalgia, rash and muscle spasm. In addition, patients in the IM + IFN group suffered from flu-like symptoms, impaired liver function, abnormal thyroid function and extremity sensory disturbance. It seemed that grade III or IV pancytopenia occurred more commonly in the patients in the IM + IFN group, however, there was no statistically significance.

CONCLUSIONSThe response to IM + IFN is more rapid than that to IM alone, especially for the low- and intermediate-risk patients. It seems no benefit of the addition of IFN to treatment of high-risk patients. During the period of 36 months, survival rate in the IM + IFN group is not higher than that in IM group, and it is possible to increase the side effects of pharmaceutical drugs.

OBJECTIVETo explore effects of Shenqi preparation,Traditional Chinese Medicine, on anti-fatigue and anti-oxidant functions.

METHODSOne hundred and twenty mice were randomly divided into control group and 3 experimental groups. The high, medium and low-dose of Shenqi preparation were given to the 3 experimental groups respectively, while distilled water to the control group for 15 d. The loaded swimming time, the level of lactate, serum urea nitrogen (SUN), muscle and liver glycogen, liver super-oxide dismutase (SOD), the content of malondialdehyde (MDA), glutathione peroxidase(GSH-Px) were assayed.

RESULTSThe loaded swimming test showed that the exhausted swimming time of 3 experimental groups [(296.0 +/- 25.3)s, (437.0 ĝ 38.9)s, (595.0 +/- 53.9)s respectively] was longer than that of control group [(231.0 +/- 22.5)s, P < 0.05, P < 0.01]. The liver glycogen content of the high and medium-dose experimental groups were higher than that of control group respectively (P < 0.01). The SUN content of each experimental group was less than that of the control group (P < 0.01, P < 0.05). Moreover,in the medium and high dose experimental groups, less accumulation of lactate was found (P < 0.01, P < 0.05), and the content of liver SOD and GSH-Px was higher (P < 0.01, P < 0.05). The content of liver MDA in high-dose experimental group was less than that of the control group (P < 0.05).

CONCLUSIONShenqi preparation, especially the high and medium-dose experimental groups, is able to improve exercise tolerance and has anti-fatigue and anti-oxidant effects in mice.

OBJECTIVETo explore the effects of p38MAPK inhibitor SB203580 (SB) on the occurrence of acute GVHD and intestine damage after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in mice.

METHODSSixty BALB/c mice, as recipients, were randomized to control group, irradiation group, model group and intervention group. C57BL/6 mice, as donors, were raised to prepare the bone marrow cells (BMCs) and spleen cells (SCs), which were injected into irradiated recipients mice by tail vein. Except control group, other groups accepted 7.5Gy total body irradiation. Model group and intervention group were infused with BMCs 5×10⁶ and SCs 5×10⁵ by less than 4 h after irradiation. SB was injected into intervention group by intraperitoneally, but only DMSO for model group. The general status and survival rate of each group were evaluated. The expression of p-p38MAPK, Fas and FasL in intestine were determined by RT-PCR, Western blot and immunohistochemistry (IHC).

RESULTSThe weight changes of intervention group (13.00±0.50)% was significantly lighter than that of model group (25.00±0.75)% (P<0.05). The clinical score of acute GVHD in the intervention group (3.33±0.82) was significantly lower than that of model group (6.33±1.36) (P<0.05). The expression levels of p-p38MAPK, Fas and FasL in small intestine of intervention group (1.43±0.02, 0.81±0.03, 0.97±0.03) were lower than those of model group (1.76±0.05, 1.52±0.04, 1.48±0.04).

CONCLUSIONSB inhibited the activation of p38MAPK and Fas/ FasL signal pathway and alleviated the apoptosis of small intestine. And SB could relieve small intestine damages induced by allogeneic T lymphocytes.

This study was aimed to explore the expression and significance of DNMT1 gene in bone marrow of patients with acute myelogenous leukemia (AML). The expression of DNMT1 gene was detected by real-time PCR in 30 healthy people and 126 AML patients. The results showed that the expression level of DNMT1 gene was lower in the 30 healthy people and was higher in AML patients. There was a marked decline in the expression level of DNMT1 gene after complete remission (CR) as compared with the initial treatment. The expression level of DNMT1 gene did not correlated with age, sex and the clinical characteristics at initial diagnosis such as white blood cell count and chromosomal karyotype in AML patients. The CR rate in AML patients with low expression level of DNMT1 gene was lower than that in those with high expression level. It is concluded that bone marrow DNMT1 gene level may play an important role in AML pathogenesis and can serve as an index in evaluating AML prognosis.
