The cloning of promoter is important for studying the genetic engineering and the regulation of gene expression in plants. Two promoters Os772 and Os359, which are predicted to be highly expressed in the endosperm of rice from the EST database were cloned. After construction of the Os772∶∶GUS and Os359∶∶GUS expression vectors, they were transformed into rice. X-Gluc staining of transgenic plants showed that Os772 and Os359 can promote GUS gene expression in matured endosperm but not in root, stem, leaf and flower. This result indicates Os772 and Os359 are two rice endosperm-specific promoters.

OBJECTIVETo observe the clinical efficacy and safety of Corydalis composite (CDC) combined with methotrexate (MTX) in treating rheumatoid arthritis (RA).

METHODSSeventy-six RA patients were randomly assigned to 2 groups, 37 in the treated group received the combined therapy, and the 39 received MTX treatment alone, all were treated for 12 weeks. Efficacy of treatment was evaluated adopting the standard of American College of Rheumatology (ACR), taking ACR20 as the chief criterion; ACR50, ACR70 as well as the clinical indexes and items in Health Account Questionnaire (HAQ) as the auxiliary criteria, including joint swelling index, joint tenderness index, holding power, morning stiffness time, resting pain, erythrocyte sedimentation rate (ESR), C-reactive protein. And the adverse reaction was recorded at the same time.

RESULTSAfter being treated for 4, 8 and 12 weeks, the ACR20 response rate reached 35.14%, 59.46% and 70.27% respectively in patients of the treated group, while that in the control group was 17.95%, 35.90% and 46.15% respectively, significant difference between groups was shown in the outcome of week 8 and 12 (P < 0.05). ACR50 and ACR70 improving rate at all the time points of observation were increased in the treated group, with the ACR50 improving rate at week 12 higher than that in the control group (43.24% vs. 20.51%, P < 0.05). As compared with the control group, the improvements in all the auxiliary criteria were more significant in the treated group (P < 0.05). The incidence of adverse reaction was less in the treated group than in the control group (32.43% vs. 56.41%, P < 0.05), particularly in term of the damage on liver (0 vs. 10.26%, P < 0.05).

CONCLUSIONCDC combined with MTX is more effective than MTX alone in treating active RA with less adverse reaction.

OBJECTIVETo explore the effect of Salvianolate on myosin heavy chain (MHC) in cardiomyocytes of congestive heart failure (CHF) rats.

METHODSSixty male SD rats were divided into 6 groups according to random digit table, i.e., the normal control group (NCG), the model group, the Captopril group (CAG), the low dose Salvianolate group (LSG), the high dose Salvianolate group (HSG), the Captopril and high dose Salvianolate group (CSG), 10 in each group. CHF rat model was established with peritoneal injection of adriamycin in all rats except those in the NCG. Equal volume of normal saline was peritoneally injected to rats in the NCG, once per week for 6 successive weeks. Corresponding medication was started from the 5th week of injecting adriamycin. Rats in the CAG were administered with Captopril solution at the daily dose of 10 mg/kg by gastrogavage. Rats in the LSG and the HSG were administered with Salvianolate solution at the daily dose of 24.219 mg/kg and 48.438 mg/kg respectively by gastrogavage. Salvianolate was dissolved in 2 mL 5% glucose solution and administered by peritoneal injection. Rats in the CSG were peritoneally injected with high dose Salvianolate solution and administered with Captopril solution by gastrogavage. Two mL normal saline was peritoneally injected to rats in the model group, once per day for 8 successive weeks. Eight weeks later, the cardiac function and myocardial hypertrophy indices were detected by biological signal collecting and processing system. mRNA expression levels of alpha-MHC and beta-MHC in cardiac muscle were detected by fluorescence quantitative PCR. Expressions of protein kinase C (PKC) in cardiac muscle were detected by Western blot.

RESULTSCompared with the normal control group, heart mass index (HMI) and left ventricular mass index (LVMI) obviously increased in the model group (P < 0.01). Compared with the model group, HMI and LVMI decreased in HSG, CAG, and CSG groups (P < 0.05, P < 0.01). It was more obviously lowered in the CSG group than in the CAG group (P < 0.05). Compared with the NCG, the mRNA expression level of alpha-MHC in cardiac muscle decreased, the mRNA expression level of p-MHC and the expression of PKC in cardiac muscle increased in the model group (P < 0.01). Compared with the model group, the mRNA expression level of alpha-MHC in cardiac muscle was increased, and the mRNA expression level of beta-MHC and the expression of PKC in cardiac muscle were decreased in HSG, CAG, and CSG groups (P < 0.05, P < 0.01). There was statistical difference between the CSG group and the CAG group (P < 0.05).

CONCLUSIONSSalvianolate could up-regulate the mRNA expression level of alpha-MHC, and down-regulate the mRNA expression level of beta-MHC in cardiac muscle. Its mechanism might be related to decreasing the expression of PKC.

Objective To study the accuracy and the clinical significance of sentinel lymph node biopsy (SLNB)after neoadjuvant chemotherapy for breast cancer.Methods A total of 90 patients with StageⅡorⅢbreast cancer and negative axillary node after neoadjuvant chemotherapy were enrolled in the study.Mapping proce- dure and SLNB were performed using methylene blue injected at the site of the primary breast cancer,followed by the axillary lymph node dissection.Results The sentinel lymph node(SLN)was successfully identified in 82 out of 90 patients(91.1%).The number of sentinel harvested nodes ranged from 1 to 4(average 1.6).The accuracy of SLNB to predict the axillary lymph node status was 93.9 %(77/82),the sensitivity,positive predictive value,nega- tive predictive value and false negative rate were 87.5 %(40/45),100 %,88.1% and 11.1%(5/45),respectively. The SLN identification rate tended to be higher and false negative rate tended to be lower in patients with T2 prima- ry tumor before neoadjuvant chemotherapy.Conclusion Our study indicated that SLNB after neoadjuvant chemotherapy in patients with StageⅡorⅢbreast cancer had a similar effect as SLNB in non-neoadjuvant studies. SLNB was considered to be able to accurately predict the axillary lymph node status in patients with T2 primary tu- mor before neoadjuvant chemotherapy.

Mycelial morphology are exploited a great influnence to the metabolites of fungi. The effect of the mycelial morphology on producing lycopene by Blakeslea tripora was investigated. The results indicated that pellets has little role on fermentation when adding kerosene and triton-x100, However, The content of lycopene in the medium reached to 98.6mg/L by adding Ig/L span-20, forming dispersed mycelia, which is 3 times of the control experiments.
