Objective: To evaluate the clinical efficacy of sinew-regulating bone-setting manipulations plus exercise therapy in treating chronic non-specific low back pain (CNLBP). Methods: A total of 65 CNLBP patients were divided into two groups by the random number table method. Thirty-three cases in the treatment group were intervened by sinew-regulating bone-setting manipulations plus exercise therapy; 32 cases in the control group were intervened by medium-frequency electrotherapy plus exercise therapy. Before and after treatment, visual analog scale (VAS), dynamic and static muscle endurance of low back, median frequency (MF) of surface electromyography (sEMG) and Oswestry disability index (ODI) were used to evaluate the low back function. The therapeutic efficacy was estimated after treatment. Results: The two groups each had 2 dropouts during the study. The total effective rate was 90.3％ in the treatment group versus 66.7％ in the control group, and the between-group difference was statistically significant (P<0.05). After treatment, the VAS score, dynamic and static muscle endurance of low back, MF of sEMG and ODI score all changed significantly in both groups (all P<0.05); all the items in the treatment group were significantly different from those in the control group (all P<0.05). Conclusion: Sinew-regulating bone-setting manipulations plus exercise therapy can effectively release pain in CNLBP patients, increase muscle endurance of the low back and improve the quality of life, and its therapeutic efficacy is more significant than that of medium-frequency electrotherapy plus exercise therapy.

Objective To evaluate two methods measuring alveolar bone loss by micro computed tomography (micro-CT)based on periodontitis model in mice.Methods The silk ligatures were tied around the right maxillary second molars of mice to induce periodontitis model.The right half maxillaries of mice model were harvested for micro-CT analysis.Three dentists were recruited for the measurement with two different methods:Modified tomography (T) method and reconstruction (R) method.Accuracy and consistency of each method were estimated by standard deviation (SD).Results The SDs of R method managed by the same operator (measurement for 3 times) or different operators (3 operators) were 34.87μm and 35.67 μm respectively,while that of T method was 7.82 μm and 14.24 μm respectively.The SDs of T method were significantly lower than those of R method (both P＜0.05).Conclusion T method is more accurate and consistent than R method for evaluating alveolar bone loss in mice periodontitis model.

HPLC analysis was performed to study the changes in chemical composition of ginseng extracts prepared from high quality ginseng with 0, 2, 4, 8 h of steamed times. An UFLC-MS/MS multiple-reaction monitoring (MRM) quantitative analysis was made to investigate the pharmacokinetic behavior differences of ginsenosides in mice ig administered of ginseng extracts with different steamed times in the negative ion mode, with Digoxin as the internal standard substance. The mice were injected with LPS to establish inflammation model after ig administration of ginseng for a week and the contents of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in mice plasma were detected by ELISA, in order to study on anti-inflammatory effects of ginseng with different steamed times. It was determined that levels of TNF-α and IL-1β were significantly decreased in inflammation model group ig administered of ginseng extracts with 8h of steamed time. The results showed that the chemical components in ginseng changed after steaming and the components into the blood changed, correspondingly. Ginseng with steamed 8 h contributes to anti-inflammatory effects. These results provided an experimental basis for revealing the active substance basis and dose-effect relationship of ginseng on anti-inflammatory effect.

OBJECTIVETo observe the expression of phospholipid scramblase 1 (PLSCR1) in matrine (MAT) induced differentiation of all-trans retinoic acid (ATRA) resistant acute promyelocytic leukemia (APL) cells, and to explore its correlation to cyclic adenosine monophosphate (cAMP)/protein kinase A (PKA) signal pathway.

METHODSNB4 (an APL cell line sensitive to ATRA) and NB4-R1 (a resistant strain of ATRA) were observed as subjects in this study. Effects of combined treatment of 0.1 mmol/L MAT and 1 [mol/L ATRA on the differentiation of two cell lines were detected using nitroblue tetrazolium (NBT) reduction test and flow cytometry (CD11b). Expressions of PML/RARot and PLSCR1 protein/gene were detected using Western blot and Real-time fluorescence quantitative PCR assay. Meanwhile, H89, PKA antagonist, was used to observe cell differentiation antigen and changes of aforesaid proteins and genes.

RESULTSMAT combined ATRA could significantly elevate positive rates of NBT and CD11 b in NB4-R1 cells, and significantly down-regulate the expression of PML/RARapha-fusion protein/gene (P < 0.05, P < 0.01). ATRA used alone could obviously enhance the expression of PLSCRI in NB4 cells at protein and mRNA levels (P < 0.01). But the expression of PLSCR1 was up-regulated in NB4-R1 cells, but with statistical.difference only at the protein level (P <0. 01). In combination of MAT, PLSCR1 protein expression was further elevated in the two cell lines (P < 0.01). Besides, there was statistical difference in mRNA expressions in NB4-R1 cells (P < 0.05). All these actions could be reversed by treatment of 10 micromol/L H89 (P < 0.05, P < 0.01).

CONCLUSIONMAT combined ATRA could significantly induce the differentiation of NB4-R1 cells, and inhibit the expression of PML/RARalpha fusion gene/protein, which might be associated with up-regulating PLSCR1 expression.

Objective:To observe the effect of liver-soothing and mind-regulating acupuncture method on the resting-state electroencephalography (EEG) in rats with post-traumatic stress disorder (PTSD),and to provide evidence for the effect mechanism study and clinical application of acupuncture intervention for PTSD.Methods:Sixty Sprague-Dawley (SD) rats were randomly divided into a blank control group,a model group,a grasping group,a paroxetine group and an acupuncture group,with 12 rats in each group.Except for rats in the blank control group,rats in the other groups were subjected to preparing the PTSD models using 'incarceration plus electric shock' method.After interventions,changes in rat behavior of each group were observed;changes in resting-state EEG were collected and analyzed with multichannel EEG acquisition and analysis system,and image analysis and statistical processing were performed.Results:Compared with the blank control group,the average escape latency in the model group was significantly longer (P＜0.05),and the times of crossing the platform and the effective areas were all significantly reduced (P＜0.01).Compared with the grasping group,the average escape latencies in the paroxetine group and acupuncture group were significantly shortened (P＜0.05),and the times of crossing the platform and the effective areas were all significantly increased (P＜0.05).There were no significant differences in the average escape latency,the times of crossing the platform and the effective areas between the acupuncture group and paroxetine group (all P＞0.05).Compared with the blank control group,the α-wave power spectrum value in the model group was significantly decreased,and the power spectrum values of β-wave,δ-wave and a-wave were significantly increased (all P＜0.01);compared with the grasping group,α-wave power spectrum values in the paroxetine group and acupuncture group were significantly increased (both P＜0.01),and the power spectrum values of β-wave,δ-wave and a-wave were decreased significantly (all P＜0.01).The power spectrum values of α-wave,β-wave,δ-wave and (e)-wave of rats in the acupuncture group were not significantly different from those in the paroxetine group (all P＞0.05).Conclusion:Liver-soothing and mind-regulating acupuncture method can significantly improve the abnormal EEG activity in PTSD rats,which may be one mechanism of liver-soothing and mind-regulating acupuncture method in effectively affecting the brain function in PTSD rats.

Objective To investigate the mechanism of BVT. 2733 on insulin resistance, by using diet-induced obese (DIO) mice model. Methods After having been balanced for 3 days, the C57BL/6J mice were randomly divided into a normal diet group and a high-fat diet (HFD) group. After 20 weeks, the obese mice were further randomly divided into an obese control group, a BVT. 2733 group and a pioglltazone (PGZ) group and they were orally administered with placebo, BVT. 2733 and PGZ separately for two weeks.Adiponectin and leptin mRNA expression levels from adipose tissue were analyzed with real-time quantitative PCR. The levels of plasma glucose, serum insulin and adiponectin were measured with biochemical technology, radioimmunoassay and ELISA. Adipocyte sizes were observed with immunohistocbemistry.Results The body weight, plasma glucose and serum insulin levels raised(P<0.05)in the HFD group and the adipocyte sizes were bigger. Serum insulin levels significantly reduced (P<0.05) and adipocyte sizes reduced, while plasma adiponectin level raised (P<0.01)in the two treatment groups as compared with those in obese controls. Both the mRNA expressions of adiponectin and leptin upregulated(P<0.05)in the PGZ group, but their expressions in the BVT. 2733 group did not alter significantly. The body weight of the mice reduced significantly in the BVT. 2733 group. Conclusion BVT. 2733 can reduce body weight significantly and improve insulin resistance, but cannot influence the expression of adipocytokines.
