OBJECTIVETo evaluate clinical significance of waist soft tissue tension detection in treating chronic nonspecific low back pain.

METHODSFrom August 2011 to March 2012,60 patients with chronic nonspecific low back pain were divided into two groups (sliver needle group and TCM fumigation group) according to propotion of 1:1. In sliver needle group, there were 17 males and 13 females aged from 28 to 55 years old with an average age of (45.70 +/- 4.15), treated with sliver needle; In TCM fumigation group,there were 19 males and 11 females aged from 27 to 55 years old with an average age of (43.03 +/- 5.86), treated with TCM fumigation. Changes of force-displacement distance (FDD), specific absorption rate (S) of two groups were observed before treatment, 1 week and 3 months after treatment respectively, VAS scoring and Roland-Morris disability questionnaire (RMDQ) were used to access clinical effects.

RESULTS(1) VAS score of silver needle group was 4.77 +/- 0.78, 1.99 +/- 1.08 and 2.55 +/- 0.94, respectively before treatment, at 1 week and 3 months after treatment,while VAS score in TCM fumigation group were 4.43 +/- 0.61, 2.48 +/- 0.71 and 3.05 +/- 0.86, respectively. VAS score of two groups after treatment were sigificant decrease than that of before treatment (P < 0.05). There was no sigificant differences between two groups before treatment, but sliver needle group performed well in analgesia than TCM fumigation group, and had obvious differences (P < 0.05). RMDQ score of silver needle group was 13.63 +/- 1.96, 5.87 +/- 2.33 and 6.53 +/- 2.89, respectively before treatment, at 1 week and 3 months after treatment, while RMDQ score in TCM fumigation group were 13.40 +/- 2.01, 6.90 +/- 2.31, 9.23 +/- 2.87, respectively. There was no significant differences between two groups before treatment and 1 week after treatment (P > 0.05), and had obvious differences between two groups at 3 months after treatment (P < 0.01). Both groups could obvious improve dysfunction caused by chronic low back pain, and curative effect of sliver needle groups was more endurable. (2) Following-up at 3 months after treatment, FDD of multifidus, erector spinae of effected side and multifidus of healthy in sliver needle group were obvious increased (P < 0.05); In TCM fumigation group, FDD of multifidus and erector spinae on both side were increased at 1 week after treatment (P < 0.05), but had no significant meaning at 3 months after treatment on health side (P>0.05). There was no significant meaning before treatment (P > 0.05), FDD of multifidus, erector spinae of effected side in sliver needle group were obvious increased at 1 week after treatment (P < 0.05); but no obvious meaning on health side. FDD of both side in sliver needle group were obvious increased at 3 months after treatment. (3) There was correlation among differences of FDD in multifidus and erector spinae, VAS score and differences of RMDQ, and Spearman correlation coefficient R was 0.517, 0.811, 0.746 and 0.625; There was correlation between items of soft tissue tension and sympotoms, function and life quality. Conclusion:Soft tissue tension detection can effectively manifest degree of pain and dysfunction of low back, and improve objectivity of therapeutic evaluation for chronic low back pain.

OBJECTIVEThe multi-center, randomized, double-blind, double-simulated and positive-control trial was used to verify the contribution degree of Bushen Huoxue for the treatment of ovulatory dysfunction caused infertility, which provided scientific basis for clinical treatment.

METHODAccording to diagnostic, inclusion and exclusion criteria, we observed 349 patients which were divided into the treated group (n = 177, treated with Bushen Huoxue ricipe) and control group (n = 172, treated with clomiphene). Ovulation rate, pregnancy rate, clinical effective rate of traditional Chinese medicine, endometrium and diameter of dominant follicle were observed. Serum reproductive endocrine hormones were assayed before and after treatment.

RESULTThe treated group showed ovulation rate of 69.34%, with pregnancy rate of 41.35%. The clinical effective rate of treated group and control group were 91.73% and 80.77%. There was remarkable difference in endometrium (P < 0.05) and remarkbale difference in sex hormones PRL and E₂in treated group at prior-treatment and post-treatment (P < 0.05). No adverse effects were found in the experiment. Security indicators did not show abnormal change.

CONCLUSIONThe comparison between the two groups showed that the treated group was significantly different from control group in the pregnancy rate (P < 0.05), without notable difference in ovulation rate. There was significant difference in clinical effective rate between the treated group and control group. Both the two groups could contribute to the mature development and discharge of the follicles. The growth of endometrium and endometrial receptivity in the treated group were higher than control group. The treated group has regulatory effect on PRL and E₂.

OBJECTIVETo compare the changes of nucleus pulposus after in vitro culture of rabbit whole intervertebral disc and spinal motion segment.

METHODSTwenty-one New Zealand white rabbits which were randomly divided into organ group with 8 rabbits and segment group with 13 rabbits. Fifty intervertebral discs and 50 spinal motion segments were harvested respectively under aseptic conditions from two groups. These specimens were maintained in organ culture with hyperosmotic media (410 mOsm/kg), then 10 discs of the two groups were observed respectively by HE staining, immunohistochemistry of collagen type III, proteoglycan content and cells viability of nucleus pulposus before culture and at 3, 7, 14, 21 days after culture.

RESULTSHE staining showed the intervertebral disc tissue structure remained intact after culture of 21 days organ group and 14 days segment group,but there was severely degenerated of 21 days segment group. The intensity value of type II collagen immunohistochemical staining in the nucleus pulposus were not changed significantly between 21 days organ group and 14 days segment group (P > 0.05), but the staining of segment group at 21 days became shallower, there was significant difference compared with before each time points and organ group at 21 days (P < 0.05). PAS/AB staining of proteoglycan of nucleus pulposus showed that there were not decrease of tinting strength of two groups within 7 days, but the strength weakened slightly of two groups at 14 days, and the tinting strength became weaker at 21 days segment group, the change is more obvious than the organ group. The intensity value of fluorescence staining of nucleus pulposus cells was not changed significantly within 7 days of two groups (P > 0.05), the intensity value decreased slightly at 21 days organ group and 14 days segment group, but there were no significant difference compared with before time points (P > 0.05) however at 21 days segment group the intensity decreased as cells viability of nucleus pulposus decreased,and there was a significant difference compared with before each time points and organ group at 21 days (P < 0.05).

CONCLUSIONIt is not obviously degenerated of the discs of organ group cultured within 21 days and segment group cultured within 14 days, but there was significant degeneration of the intervertebral disc of segment group after cultured 21 days, so the rabbit spinal motion segment can be used on research about the biomechanics of intervertebral disc as a vitro experimental model within 14 days.

Aim To investigate the effect of asiatic acid on apoptosis and autophagy in human glioblastoma T98G cells. Methods MTT colorimetry was employed to assay the cellular proliferating activity. The fluores-cence microscope and Hoechst 33258 staining were used to detect the morphological changes. The cell ap-optosis and autophagy were analyzed by flow cytometry with Annexin-V/7-AAD and MDC staining respective-ly. The expressions of associated proteins were detected by Western blot to analyze the mechanism of apoptosis and autophagy. Results MTT assay showed that the growth of T 9 8 G cells was inhibited by asiatic acid ( IC50 =46. 3 μmol · L-1 ) . Annexin V/7-AAD stai-ning and Western blot revealed that asiatic acid in-duced apoptosis in T98 G cells by reducing the expres-sion of Akt, decreasing the mitochondrial membrane potential, and increasing the expression of Caspase-3. MDC staining and Western blot showed that the per-centage of MDC-positive cells was decreased and the expressions of Beclin-1 , LC3-II and Atgs were inhibi-ted by asiatic acid treatment. 5 μmol·L-1 chloroquine was used to up-regulate the expressions of LC3-Ⅱand Beclin-1 . Asiatic acid-inhibited autophagy was blocked and the total apoptotic rate was reduced remarkably. Conclusion Asiatic acid suppresses T98 G cells pro-liferation by inducing apoptosis and inhibiting cell au-tophagy, and the very role of inhibiting autophagy could promote apoptosis to a certain extent.

To establish quality standards of Euonymus fortunei, and supply scientific evidence for the quality control of Euonymus fortunei. Empirical and microscopic identification methods were adopted to observe morphological and histological characters. The contents of water, total ash, acid-insoluble ash and alcohol-soluble extractive were analysed according to the methods of Chinese Pharmaco- poeia (2010). Dulcitol and reference herbs were used to identify materia medica of Euonymus fortunei by TLC method. The total flavonol glycosides contents were analysed by HPLC method, using quercetin and kaempferol as reference substances. Quercetin and kaempferol were separated on a C18 column (4.6 mm x 250 mm, 5 μm) with methanol-0.1% formic acid(51:49) as the mobile phase and detected at 366 nm. The flavonoid aglycones content was then multiplied by a conversion coefficient, and the result was the total flavonol glycosides content. The macroscopical identification, microscopic features and TLC methods were proper. The average contents of water, total ash, acid-insoluble ash, alcohol-soluble extractive and total flavonol glycosides were 8.76%, 6.48%, 0.31%, 17.48% and 0.211% , respectively. The quality standards established on the basis of the research results were suitable for the quality evaluation of Euonymus fortunei.
