Objective: To observe the clinical efficacy of Nie-pinching the spine, puncturing Sifeng (EX-UE 10) plus Chinese herbs in treating pediatric anorexia due to dysfunction of spleen in transportation. Methods: A total of 64 kids were randomized into an observation group and a control group by the random number table method, with 32 cases in each group. Patients in both groups received Jian Pi Kai Wei (strengthening spleen and stomach) powder according to pattern differentiation of traditional Chinese medicine (TCM). In addition, patients in the observation group received Nie-pinching the spine and puncturing Sifeng (EX-UE 10). Nie-pinching the spine was applied twice a week, and puncturing Sifeng (EX-UE 10) was performed once a week, with 2 weeks counted as 1 course of treatment. After 2 courses of treatment, the body mass index (BMI), peripheral blood leptin level and the microelements Zn, Fe and Se were compared at different time points (before treatment, after the first and second courses of treatment), as well as the therapeutic efficacy and onset time. Results: After 2 courses of treatment, 31 cases in each group were evaluated. After the 1st course and the 2nd course, the BMI and serum Zn, Fe and Se levels in the observation group increased significantly (all P<0.05), the leptin level decreased substantially (both P<0.05); the BMI in the control group showed a substantial rise (P<0.05), while the Zn, Fe and Se levels slightly increased showing no statistical significance (all P>0.05), and the leptin level decreased but the difference showed no statistical significance (P>0.05). After the 1st and the 2nd courses of treatment, the BMI, serum Zn, Fe and Se levels increased more significantly (all P<0.05), and the serum leptin level decreased more significantly (both P<0.05) in the observation group than in the control group. After the 2nd course, the total effective rate and recovery rate in the observation group were both higher than those in the control group (both P<0.05), together with a quicker onset time (P<0.05). Conclusion: Nie-pinching the spine, puncturing Sifeng (EX-UE 10) plus Chinese herbs is effective for pediatric anorexia due to dysfunction of spleen in transportation. It can decrease leptin, increase Zn, Fe and Se levels, alleviate apositic symptoms and increase BMI in the kids.

Objective To investigate the expression pattern of Nrf2 in the lung of septic rat and preliminary analysis of the role of Nrf2 in the development of sepsis. Methods Wistar rats were used in this study, it was divided into 4 groups, including normal control group, pure burn group, burn with staphylococcus sepsis group, burn with pseudomonas sepsis group. According to the different time intervals such as 2 hours, 8 hours, and 24 hours, it was divided into three sub-group after injection of bacteria. The expression of Nrf2 in the lung at different time intervals was determined. Results Nrf2 mRNA in the lungs of normal rats was high expression （74.0±7.0）, Nrf2 mRNA in the lungs of pure burns rats obviously down-regulated, respectively as 34.5±1.9,50.4±2.2,32.1±1.4, （t＝5.69～14.63,P＜0.01）. Nrf2 mRNA in burn sepsis caused by Staphylococcus aureus in lung tissue of rats down-regulated expression, respectively as 53.1±5.0,14.4±1.6,48.5±1.9,and reached peak at 8 h（t＝5.59～29.3,P＜0.01）. Pseudomonas aeruginosa burn sepsis didn't induced Nrf2 mRNA in the lung tissue, but it showed a downward trend at 2h（71.0±8.1,P＞0.05）and markedly reduced after 8, 24 h（24.8±2.1,4.1±2.0,t＝21.33,68.1,P＜0.01）.Conclusions The distribution of Nrf2 mainly localized in immune organ, and it directly took part in the post burn immune response.

Objective To explore the therapeutic effects of human glial cell line-derived neurotrophic factor (GDNF)-engineered rat neural stem cell (NSC) transplantation in rat model of Parkinson's disease ( PD) . Methods SD rats received a single injection of 24 μg of 6-hydroxydopamine (6-OHDA) at two sites in right striatum. Then 10 days after surgery, the successful animal models of PD were divided into 3 groups: PD model group ( 2 μl transplantation media was injected in right striatum), NSC group (transplanted were 2×10~5 NSCs infected by bare lentivirus) and GDNF group (transplanted were 2×10~5 GDNF-engineered NSCs). The rotation scores were assessed 5 weeks, 7 weeks and 9 weeks after transplantation. The dopaminergic neurons in substantia nigra ( SN ) were analyzed quantitatively using immunohistochemistry for tyrosine hydroxylase (TH), and the dopamine and its metabolites, dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA) were analyzed 9 weeks after transplantation by high performance liquid chromatography ( HPLC) . Results GDNF-engineered NSC transplantation could effectively improve the behavioral performance in rats. At the 5th week after cell transplantation, the rotation turns within 90 min were (993. 9±159. 1) turns, (956. 7±136. 3) turns and (433. 6±100. 9) turns in PD model group, NSC group and GDNF group respectively (F=95. 694, P = 0. 000). At the 7th week, the rotation turns within 90 min were (964. 2 ± 152.0) turns, (909. 2 ± 136. 3) turns and (399. 4±84. 4) turns in PD model group, NSC group and GDNF group respectively (F = 106. 134, P=0. 000). At the 9th week, the rotation turns within 90 min were (909. 5±152. 2) turns, (865. 5± 129. 1) turns and (312. 2±63. 7) turns in PD model group, NSC group and GDNF group respectively (F= 151. 100, P = 0.000). GDNF-engineered NSC transplantation could significantly increase the levels of dopamine and its metabolites in injured striatum. The concentrations of dopamine in injured striatum was higher in GDNF group than that in PD model group and NSC group C(7. 5±0. 8) ng/mg vs. (3.3±0.3) ng/mg and (3. 7±1. 3) ng/mg, F=59. 543, P = 0. 0003. The level of DOPAC was higher in GDNF group than that in PD model group and NSC group C(0. 9±0. 1) ng/mg vs. (0. 5± 0. 1) ng/mg and (0. 6±0. 2) ng/mg, F= 17. 293, P=0. 000]. The concentration of HVA in injured striatum was higher in GDNF group than that in PD model group and NSC group [(0. 9±0. 1) ng/mg vs. (0.5±0. 1) ng/mg and (0. 6±0. 2) ng/mg, F=35.175, P = 0.000]. Conclusions engineered NSC transplantation improves the function of dopamine system in SN and striatum, and GDNF gene therapy has potential clinical value.

Objective:To study how to guide the individual dose of clopidogrel in line with the genetic testing results. Methods:Clinical pharmacists decided how to optimize the prescription of clopidogrel according to the genotype combined with the drug metabolism and drug interactions for three patients respectively with slow clopidogrel metabolism,intermediary metabolism and super fast metabolism. Results:The slow clopidogrel metabolism patient with subacute stent thrombosis after half a month of coronary stenting was switched to orally administrate with ticagrelor. The super fast metabolism patient suffered from repeatedly subcutaneous hemorrhage with antiplatelet therapy was suggested to lower the dose of clopidogrel,temporarily withdraw Maixuekang capsules and conventionally administrate with vitamin C tablets orally. The intermediary metabolism patient with late stent thrombosis co-treated with lansoprazole was suggested to increase the dose of clopidogrel or use ticagrelor instead,and when it was necessary,panxitorazole,ray Bella or the other ranitidine acid suppression drugs such as ranitidine could be considered. Conclusion:Through genetic testing and drug interactions,clinical pharmacists guide the clinical use of clopidogrel and the optimization of antiplatelet therapy.

To develope a 5 lipoxygenase inducible expression system for further understanding the function and signal transduction pathway of 5 lipoxygenase, providing information for drug screening.The 2 kb 5 LO cDNA sequence containing HindⅢ site was generated by PCR using pEGFP 5LO as a template. Full length 5LO cDNA was subsequently cloned into the corresponding Pst Ⅰ and Sal Ⅰ sites of the plasmid pBI G to generate the mammalian expression vector pBI 5LO. HeLa Tet On cell line was co transfected with pBI 5LO and pTK Hyg plasmids. Inducible expression of target gene was detected using X gal histochemical staining of cell monolayers for ? galactosidase after incubating the transfected cell line with 1 ?g/ml doxycycline for 48 h.The HindⅢ restriction digest site was inserted into polyclonal site of pBI G and recombinant vector pBI 5LO was constructed. The desired recombinant plasmid pBI 5LO was identified by restriction analysis, and orientation and junctions were confirmed by sequencing. Induction of the target gene expression by doxcycline treatment was demonstrated by X gal histochemical staining and nuclei of the cells that have expressed the pBI 5LO expression vector were brilliant blue.The 5LO inducible expression system is established successfully and it works well in cell model.

Objective To establish a sensitive,specific,simple and high-throughput method for detection of the epidermal growth factor receptor (EGFR) mutation in the plasma samples of patients with non-small cell lung cancer (NSCLS) by the use of mutant-enriched liquid chip (MEL) assay.Methods The specific probes for the EGFR exon19 E746-750 deletion,exon 21 L858R mutation and wild-type sequence were designed and coupled to the microspheres coding with different fluorescent dye.The probe coupling efficiency was verified by crossing hybridization test with biotin-labeled reverse sequence.A blood-based MEL approach which integrates a sensitive mutant-enriched PCR and quantitative high throughput liquid chip assay for assessment of EGFR mutations was developed.The sensitivity and specificity of MEL was further evaluated using the mixture with different copy numbers of mutant and wild-type plasmids as template.The mutations of exon 19 and 21 of EGFR gene in plasma samples from 201 patients with stage ⅢB or Ⅳ NSCLC who enrolled in the First Affiliated Hospital of Guangzhou Medical College from September 2008 to April 2010 were analyzed by both the MEL and the mutant-enriched PCR assay.The result comparison was made between direct sequencing and MEL in 50 cases whose EGFR gene type had been tested by MEL and mutantenriched PCR.The correlation of EGFR gene mutation and the response to the Geftinib treatment was analyzed in 16 patients with lung adenocarcinoma as well.Results The probes were successfully coupled to the microspheres encoding with different fluorescent dye,and could be specifically recognized by the corresponding target sequence.The MEL was capable of detecting as few as 10 copies of EGFR mutants (sensitivity was 0.1％).Among the enrolled 201 cases of advanced NSCLC,the detection rate of the EGFR exon19 E746-750 del and exon 21 L858R was 55.7％ (112/201) by MEL assay.Conpared with mutantenriched PCR[58.2％ (117/201)],the coincidence rate was 97.5％ (196/201).There was no statistically significant difference between the results of mutant-enriched PCR and MEL (x2 =3.20,P ＞ 0.05).The mutations detection rate was 22.0％ (11/50) by directing sequencing,which was significantly lower than by MEL[50.0％ (25/50),x2 =12.07,P ＜ 0.05].Among the 16 patients treated with Gefitinib,9 cases who had EGFR mutation showed a higher response rate(P =0.041)and prolonged progression-free survival (x2 =6.76,P =0.009) after the treatment compared to those 7 who without EGFR mutation.Conclusions A new method of MEL with accuracy,specificity,fast and high-throughput is established for the detection of EGFR 19 E746-750 deletion and exon 21 L858R mutations in plasma from advanced NSCLC patients.It has the ability to provide the most direct and valuable guidance for clinicians to make decision on EGFR tyrosine kinase inhibitors therapy in the advanced NSCLC paticnts.
