As a common disease in clinical, the treatment of lumbar disc herniation (LDH) focused on local intervertebral disc, such as surgery and other interventional therapy treatment, but postoperative complications and recurrence rate has been a difficult problem in the field of profession. With the development of spine biomechanics and anatomy, researches on lumbar herniation also increased. Researchers discovered that the incidence and prognosis of LDH were inseparable with local muscle and soft tissue. As the deep paraspinal muscles, multifidus muscle plays an important role to make lumbar stability. Its abnormal function could reduce the stable of lumbar spine, and the chronic lumbar disease could also lead to multifidus muscle atrophy.

Objective To investigate the factors affecting the stability of the volatile oil extracted fromYinqiaosan Decoction.Methods The main chemical compositions and the extraction repetitiveness of the compound volatile oil were determined by GC-MS, and the stability of multiple extracted volatile oil was studied. Absorbance of the compound volatile oil was used as the evaluation index, and the factors affecting the stability of the of the compound volatile oil were investigated, such as illumination, temperatures and pH values of volatile oil solution and metal ions.Results The results of the GC-MS chromatograph indicated that the main chemical compositions of the compound volatile oil extracted fromYinqiaosan Decoction twice were the same. The results of the stability of the volatile oil showed that the preservation temperature and illumination affected the stability of the volatile oil to a certain extent. The absorbance values of the compound volatile oil changed slowly when it was stored at a relatively low temperature (4℃) and shielded from light, and it was less stable when stored in normal temperature and under illumination. Meanwhile, the absorbance of the compound volatile oil changed quickly in acid or alkaline solutions and was in instability. The metal ions, such as Cu2+ and Fe3+, have chemical reactions with the compositions of the compound volatile oil and there was a big change in the UV-Vis spectrum of the compound volatile oils.Conclusion The compound volatile oil should be stored at a relatively low temperature (4℃) and shielded from light. At the same time, it should be stored avoiding acids, alkaline and the metal ions, such as Cu2+ and Fe3+, to guarantee its stability. This study provides a reference for the preservation conditions and the preparation conditions of the compound volatile oil extracted fromYinqiaosan Decoction.

OBJECTIVETo explore the objective special features and role of various indexes of treadmill exercise test (TET) in patients of coronary heart disease (CHD) caused angina pectoris with Qi-Yin deficiency syndrome (QYD) with or without accompanied phlegm and blood stasis syndrome (PBS), to provide references for preventing and treating CHD in clinical practice.
METHODSOne hundred and one patients, whose diagnosis measured to the diagnostic standard and the inclusion criteria of angina pectoris and CHD, were classified according to their TCM syndrome type to two groups, the QYD without PBS group (49 cases) and the QYD with PBS group (52 cases). TET was conducted on all the patients. The relative parameters were measured and compared.
RESULTSAs compared with the QYD without PBS group, in the QYD with PBS group, (1) the TET positive rate was higher; (2) total exercise time was lesser; (3) the maximal metabolic equivalent (Max MET) was lower; (4) the average depression of ST segment at the exercise endpoint of test (mV) was higher; (5) the time of ST segment depressed for 0.1mV (min) was longer; (6) the metabolic equivalent during ST-segment depressed by 0.1mV was shorter; and (7) the change of QRS wave time-limit before and immediately after TET was more evident. Moreover, in the testing time more patients revealed angina episode after exercise, and less patients had their heart rate reached the requirement in the QYD with PBS group than those in the QYD without PBS group. Comparison between the two groups in all the above-mentioned indices showed significant difference respectively (P < 0.01 or P < 0.05).
CONCLUSIONPatients with CHD caused angina pectoris of QYD with PBS are worse in the tolerance for exercise and severer in pathological change of coronary artery than those in those without PBS, they belong to the severe phase of TCM syndrome.

P210(bcr/abl) fusion gene is indispensable for generation and progression of chronic myeloid leukemia (CML). Small molecule inhibitors, such as imatinib, are effective for P210(bcr/abl) gene mediated CML, but drug resistance may occur. The unique fusion junction of P210(bcr/abl) gene is an attractive target for therapeutic intervention using RNA interference (RNAi). This study was purposed to constructed the BaF3 cell line by viral vector which can stably express P210(bcr/abl) shRNA and P210(bcr/abl) mRNA at the same time, and investigate the effect of lentiviral-victor-delivered shRNA on P210(bcr/abl) gene expression. The infective rate of lentiviral vector on BaF3 cells with P210(bcr/abl) gene was assayed by fluorescent microscopy; the cell proliferation ability was determined by trypan blue exclusion; the P210(bcr/abl) mRNA and protein expressions were detected by RT-PCR and Western blot respectively. The results found that stable expression of the P210(bcr/abl) shRNA resulted in obvious inhibition of P210(bcr/abl) mRNA and protein expression and increased sensitivity of these P210(bcr/abl) gene transformed Ba/F3 cells to imatinib. The IC(50) to imatinib in these cells decreased < 50% as compared with Ba/F3-P210(bcr/abl) cells which did not express P210(bcr/abl) mRNA. The survival time of the lethal dose irradiated mice induced by intravenous injection of these Ba/F3 cells was longer than the other group induced by Ba/F3-P210(bcr/abl). It is concluded that stable expression of shRNA targeting the P210(bcr/abl) gene fusion junction may potentiate the effects of conventional therapy for CML.
