Objective To evaluate the efficacy of Duhuo-Jisheng decoction combined with traditional manipulation for the patients with lumbar intervertebral disc herniation.Methods A total of 126 patients with orthopedic inpatients were enrolled and divided into two group by random number table method: the treatment group (63 patients) and the control group (63 patients).The control group was treated with loxoprofen sodium dispersible tablets, while the treatment group was treated with Duhuo-Jisheng decoction and traditional manipulation. Both groups were treated for 2 courses. After treatment, the patients were evaluated by VAS. The clinical effect was evaluated by Oswestry ODI.Results After treatment, the VAS scores (2.8 ± 0.3 vs. 3.5 ± 0.7, t=7.296) and ODI (10.5% ± 3 .2% vs. 15.5% ± 6.2%,t=5.688) in the treatment group were significantly lower than those in the control group. The time of symptoms relief (2.3 ± 0.5 dvs. 5.3 ± 0.7 d,t=27.681) and the time of symptoms disappearance (28.6 ± 5.7 dvs. 54.4 ± 8.2 d,t=20.506) in the treatment group were significantly less than those in the control group (both Ps<0.01). The total effective rate (95.2% vs. 87.3%) of the treatment group was significantly better than the control group (χ2=3.938,P=0.047). Team of the incidence of adverse reactions (14.2% vs. 41.2%) in the treatment group was significantly lower than that in the control group (χ2=10.128,P=0.002). Conclusions TheDuhuo-Jisheng decoction combined with traditional manipulation can alleviate the symptoms, shorten the treatment time, reduce adverse reactions for the patients with lumbar intervertebral disc herniation.

Objective To compare the influence of aging on apoptosis and the expression of apoptosis-related protein in adult and aged male Wistar rat hearts after acute coronary artery occlusion. Methods The acute myocardial infarction rat model was established by left anterior descending(LAD)occlusion.A total of 115 adult and aged rats,aged 6-24 months,were included in the study.The rats were divided into 4 groups:aged model group,aged control group,adult model group and adult control group.Animals were killed 1,3,5 hours,1 and 7 days after coronary occlusion.Hemodynamic parameters[heart rate(HR),left ventricular systolic pressure(LUSP),left ventricular end-diastolic pressure(LVEDP),±dp/dtmax)]were obtained from each group at every time points.The apoptosis and necrosis of myocardium were detected with TUNEL way and TTC stain.The expressions of Bcl-2 and Bax were analyzed with immumohistochemical stain. Results DNA fragmentation occured 1 hour after coronary occlusion and apparently peaked earlier in the aged than in the adult rat hearts.At 3 hour,the apoptotic index of aged model group was obviousily higher than that in adult model group[(51.90±23.15)%us.(18.67±17.15)%,P<0.01].The basal levels of Bcl-2 and Bax were higher in the aged than in the adult rat hearts.The expression of Bcl-2 in aged model group and adult model group were 2.7±0.9 and 1.8±0.8,P<0.05.The expression of Bax in aged model group and adult model group were 6.2±2.9 and 4.2±1.5,P<0.05. Conclusions The ability of aged rats to resist ischemia is poor,aging may alter the expressions of Bcl-2 and/or Bax,increase cardiomyocyte apoptosis,thereby,enhance the myocardial dysfunction during acute myocardial infarction.

3-Hydroxy-3-methylglutaryl-coenzyme A reductase (HMGR) is the first rate-limiting enzyme for sesquiterpene synthesis in the mevalonate (MVA) pathway. The specific primers were designed according to the transcript sequence of AsHMGR2 from the Aquilaria sinensis (Lour.) Gilg transcriptome database. The full-length cDNA of AsHMGR2 was cloned by RT-PCR and rapid amplification of cDNA ends (RACE) technology, and was analyzed at bioinformatics levels; AsHMGR2 expression profiles in different tissues and in responds to different treatments were analyzed by real-time PCR. The length of AsHMGR2 Open Reading Frame (ORF) was 1 749 bp, encoding 582 amino acids. The GenBank accession number is KC140287. Tissue expression analysis indicated that AsHMGR2 was mainly expressed in root and shoot tips, followed by stem, and was lowest in leaves. Inducible-experiments showed that the genes were induced by mechanical wound as well as chemical liquid induction, and reached the highest expression level at 6 h and 8 h, separately. The full-length cDNA of AsHMGR2 and its expression patterns will provide a foundation for further research on its function in agarwood sesquiterpene biosynthesis.

Objective To explore the value of E-flow technique in ultrasound examination of fetal pulmonary vein.Methods The pulmonary veins of 332 fetus were examined using lungs as acoustic window by two-dimensional echocardiography(2DE), color Doppler flow imaging (CDFI) and E-flow.Visualization ratios of the three methods were compared.Results The fetal pulmonary veins were displayed as following:7 cases were showed by 2DE,49 cases by CDFI and 73 cases by E-flow among 118 cases during 12 - 22 gestational weeks.The visualization ratio of E-flow was higher than that of the other two methods (P ＜0.001).Fourty-one cases were showed by 2DE, 171 cases by CDFI and 177 cases by E-flow among 214 cases during 23 - 40 gestational weeks.The visualization ratios of E-flow and CDFI were higher than that of 2DE (P ＜ 0.001).The visualization ratio of E-flow and CDFI has no distinct differrence (P ＞ 0.0167).Conclusions E-flow was sensitive to pulmonary vein blood flow and better than 2DE and CDFI in early stage of the second trimester.

Objective: To study the technological parameters of the enrichment purification process of Baohe Pills with macroporous resin. Methods: With the enriched degree of hesperidin of Pericarpium Citri Reticulatae of Baohe Pills as a marker, the optimum technological parameters of the enrichment process were studied. Results: The optimum process is that 5mL of the extract of BaoHe Pills (500mg/mL) was adsorbed for 30min with a column of macroporous resin (R15mm?H100mm) and the resin was washed with 100mL of distilled water, then the hesperidin was eluted from the macroporous resin with 100mL of 50% ethanol. Conclusion: The elutive rate of hesperidin was above 95% by means of the macroporous resin. So this process enriching the active components of Baohe Pills is feasible.
