As the major commercial source of natural rubber,Hevea brasiliensis attracts much attention.However,the heterozygous nature,long breeding cycle are strong limitations for conventional breeding.While genetic engineering,which can be used to widen the germplasm base and produce desirable agronomic traits quickly and efficiently,offers a viable alternative approach to complement traditional breeding.Comprehensive analysis indicates that in the past two decades,with calli derived from immature anther or integumental tissues of immature fruit as receptors,both biolistic and Agrobacterium-mediated transformation methods were employed for developping rubber genotypes with improved latex yield,tolerance to tapping panel dryness syndrome,producing high-value recombinant proteins,etc.Being recalcitrant to tissue culture,the transformation efficiency of Hevea is comparatively low,and the procedures are still needed to optimize.Finally,breeding objectives and strategies to improve transformation efficiency were also proposed in the review.

Objective:To analyze the distribution of UGT1A1 gene polymorphisms in Chinese Han patients with extensive-disease small cell lung cancer(ED-SCLC),and evaluate the correlation between UGT1A1 gene polymorphisms and toxicity and efficacy of irino-tecan(CPT-11) based regimen in the patients with ED-SCLC. Methods: The analysis of UGT1A1?28 and UGT1A1?6 gene poly-morphisms was performed in 67 patients with ED-SCLC admitted in our hospital from June 2011 to January 2013. The 67 cases with ED-SCLC treated with irinotecan(CPT-11) based regimen were enrolled to observe the adverse events and efficacy during the chemo-therapy, including objective responserate rate ( ORR) , progression free survival ( PFS) and overall survival ( OS) . The incidence of different genotypes was compared. Results:The distribution of UGT1A1 genotypes in the 67 patients was follows:UGT1A1?28 wild-type (WT) genotype TA6/6 (56, 83. 6%), heterozygous genotype TA6/7 (11, 16. 4%);UGT1A1?6 wild-type (WT) genotype G/G (45,67. 2%), heterozygous genotype G/A (22,32. 8%). No significant difference of PFS and OS was observed between the differ-ent genotypes. The incidence of grade 3 and 4 delayed diarrhea and neutropenia in the patients carrying UGT1A1?6 G/A was higher than that in those with WT genotype (36. 4% vs. 6. 6%, P<0. 05;27. 2% vs. 4. 4%, P<0. 05, respectively). The incidence of grade 3 and 4 thrombocytopenia in the patients carrying UGT1A1?28 TA6/7 was higher than that in those with WT genotype (27. 2%vs. 1. 8%, P<0. 05). The patients simultaneously carrying UGT1A1?28 TA6/7 and UGT1A1?6 G/A were prone to suffering 3 and 4 delayed diarrhea and neutropenia. Conclusion: UGT1A1 polymorphisms may predict the adverse events of CPT-11 in ED-SCLC, while can not predict the efficacy of CPT-11.

Object To develop a resonance scattering spectral(RSS) method for the determination of total flavone in Shuxuening Tablet, and study the cause of RSS enhancement. Methods The BSA Mo (Ⅵ) qucercetin (Qu) system was investigated by RSS method. Results There were two resonance sacttering peaks at 470 and 525 nm. The Qu concentration in the range of 0-2 4 mg/L is linear to the resonance scattering intensity I 470 nm , with a detection limit of 0 3 mg/L. Conclusion This method is simple, sensitive and suitable for the determination of total flavone in Shuxuening Tablet. The spectral results demonstrate that the formation of [BSA Mo Qu] n associated particle and the interface between the particle solid phase and water phase results to its enhanced RSS.

Objectives To explore polymorphisms of CD152 gene promoters (-1722T/C,-1661A/G) and exon1 (+49A/G) in children with idiopathic ischemic stroke and assess the association between these polymorphisms with the disease. Methods Us-ing the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method, polymorphisms in the CD152 exon1 region (+49A/G) and promoter regions (-1722T/C,-1661A/G) were genotyped in 51 Han children with idiopathic ischemic stroke and 74 healthy Han children. Results The CD152 genotypes in control group and idiopathic ischemic stroke children were consistent to principle of Hardy-Weinberg Equilibrium (HWE) byχ2 test. The CD152+49GG genotypes and G allele frequency in the patients showed a signiifcant increase compared to the controls (χ2=7.053, 6.351, P<0.05). However, the CD152-1722T/C,-1661A/G genotypes and allele frequency showed no signiifcant difference between 2 groups (P>0.05). Clinical features (hemi-paresis, dysarthria, seizures, consciousness change, and preceding infections) did not show signiifcant correlation with genotypes and frequency of the CD152+49 polymorphisms in children with idiopathic ischemic stroke (P>0.05). Conclusions The CD152+49A/G polymorphisms may relate to idiopathic ischemic stroke.

Objective To investigate the clinical features and survival status of mucosal melanoma of the nasal cavity and paranasal sinuses and to analyze the prognostic factors.Methods A retrospective analysis was performed on the clinical data of 94 patients with mucosal melanoma of the nasal cavity and paranasal sinuses treated from January 2000 to December 2012.Of the 94 patients,50 were male,and 44 were female.The median age of onset was 60 years (range,26-85 years).The primary sites were nasal cavity (86 patients),maxillary sinus (7 patients),and nasopharynx (1 patient).Cervical lymph node metastasis was observed in 10 patients (7 patients before treatment,2 patients during treatment,and 1 patient after treatment).No patient had distant metastasis.Patients were treated with surgery ± radiotherapy.The Kaplan-Meier method was used to calculate survival rates,and the logrank test was used for univariate prognostic analysis;the Cox regression model was used for multivariate prognostic analysis.Results The 1-,3-,and 5-year sample sizes were 80,54,and 50,respectively.The 1-,3-,and 5-year disease-related survival rates were 71％,33％,and 22％,respectively.Univariate analysis showed that the prognostic factors were age over 55 years (P =0.034),involvement of the posterior naris (P =0.011),involvement of the maxillary sinus (P =0.009),involvement of the hard palate (P =0.003),cervical lymph node metastasis (P =0.001),and therapeutic method (P =0.038).Multivariate analysis showed that the prognostic factors were involvement of the posterior naris (P =0.027),involvement of the orbit (P =0.005),and involvement of the hard palate (P =0.003).Conclusions The distant metastasis and local recurrence rates are high among patients with mucosal melanoma of the nasal cavity and paranasal sinuses,so combination therapy is imperative.Cervical lymph node metastasis rate is low.Rational clinical staging needs to be further explored.

Purpose To examine the regulatory effect of recombinant human fibroblast growth factor-21 on the expression of liver X receptor α and glucose transporter protein 1 in the type 2 diabetes mellitus rats.Methods The rat models of type 2 diabetic mellitus were divided into four groups at random, ic. rhFGF-21 every day, after eight weeks of these treatment, Inspect the fasting blood glucose (FBG), fructosamine(FA), triglyceride(TG), T-cholesterol(TC), high density lipoprotein cholesterol(HDL-C) and low density lipoprotein cholesterol(LDL-C) of these rats, then detecting the mRNA expression of LXRα and GLUT1 by RT-PCR.Results (1) rhFGF-21 can reduce blood glucose steadily to near normal levels in diabetic rats. (2) The expression of LXRα and GLUT1 level was significantly higher in the rhFGF-21 treatment group than that in the model group. (3) rhFGF-21 megadoses and middle doses decreased FA, TG, TC,and LDL-C and elevated HDL-C.Conclusion rhFGF-21 could regulate the mRNA expression of LXRα and GLUT1 in diabetes rats, increase basal level glucose transport, then reduce blood glucose, improve lipid metabolize dysfunction.

BACKGROUND: Bupivacaine is widely used to alleviate post-operation pain and cure acute and chronic pain caused by inflammation or cancer.Its analgesic time cannot meet the request that drug is released slowly to prolong the analgesic time in clinic.OBJECTIVE: To detect the alleviating effect of bupivacaine polylactic acid microspheres taking high molecular polymer-polylactic acid as vector in rabbits with high performance liquid chromatograph (HPLC) and traditional skin test method.DESIGN: A completely randomized controlled animal experimental study.SETTING: School of Pharmacy, Second Military Medical University of Chinese PLAMATERIALS: Sixteen New Zealand rabbits, weighing (2.58±0.17)kg were used in this experiment.INTERVENTIONS: The experiment was carried out at the Department of pharmaceutics, School of Pharmacy, Second Military Medical University of Chinese PLA between September and November 2002. ① Animal models were established according to traditional skin test method. ② Totally 16 New Zealand rabbits were randomly divided into 2 groups: Group A and Group B, with 8 in each one. 5 mg/kg bupivacaine parenteral solution was injected subcutaneously in Group A, 5 mg/kg bupivacaine polylactic acid microspheres were implanted between subcutaneous tissue and sarcolemma in Group B. We took 1.5 mL blood from ear border vein at 5, 10, 20, 30,45 minutes, 1, 2, 3, 4, 6, 8, 12 and 24 hours after administration of bupivacaine parenteral solution respectively in Group A and another 1.5 mL at 0.5, 1, 2, 3, 4, 5, 6, 8, 12, 24, 3 6, 48 and 60 hours after admistration of bupivacaine microsphere powder for index detection. ③ HPLC method was used to detect the concentration and releasing effect of bupivacaine in blood serum.MAIN OUTCOME MEASURES: Concentration change of bupivacaine in blood serum and efficacy diameter of local anesthetic.RESULTS:All the 16 rabbits entered the stage of result analysis. ①Change of bupivacaine concentration: Plasma bupivacaine concentration in Group A reached the peaked quickly after subutaneous injection with the high concentration of 2.466 4 mg/L, then declined quickly. Plasma bupivacaine concentration in Group B was relative stable, reached a peak much slowly after subcutaneous implantation, with peak concentration of 0.778 1 mg/L, and the plasma bupivacaine concentration maintained a relative low level, the mean retention time was obviously prolonged (P ＜ 0.05).② Alleviating effect of bupivacaine: The analgesic time was significantly longer in the bupivacaine microsphere group than in the bupivacaine parenteral solution group (P ＜ 0.05).CONCLUSION:Bupivacaine polylactic acid microspheres have sustained release effects in rabbits.
