Methods Sixty CRF patients were randomly allocated to treatment and control groups, 30 cases each. The control group received medication and diet control and the treatment group, herbal cake moxibustion on Shenshu, Pishu or Ganshu in addition. Pre-/post-treatment differences in serum creatinine (Scr), blood urea nitrogen (BUN), endogenous creatinine clearance rate (Ccr) and 24-h urinary protein quantity were observed in the two groups and the clinical therapeutic effects were compared between the two groups after 3 months of treatment.Results The marked efficacy rate and the total efficacy rate were 46.7% and 86.7%, respectively, in the treatment group and 20.0% and 46.6%, respectively, in the control group, and there were statistically significant differences in both between the two groups (P<0.05). There were statistically significant pre-/post-treatment differences in Scr, BUN, Ccr and 24-h urinary protein quantity in the two groups (P<0.05). There were statistically significant post-treatment differences in Scr, BUN and 24-h urinary protein quantity between the treatment and control groups (P<0.05).Conclusion Herbal cake moxibustion is an effective way to treat chronic renal failure.

The event-related desynchronization/synchronization(ERD/ERS) time courses of lower and upper alpha band rhythms during hand motor imagery are investigated respectively by Fourier Sectral Entropy (FSE) in this paper. By analyzing one group of BCI competition data, it was found that FSE within upper alpha band displays a pronounced increase and decrease over contralateral and ipsilaterai brain areas respectively at the onset of hand motor imagery, which is corresponding to the antagonistic ERD/ERS patterns in previous studies. Different from the upper alpha activity pattern, FSE within lower alpha band displays a consistent increase over both two hemispheres hand representative areas. The preliminary results show that FSE could disclose the different behaviors of the upper and lower alpha band rhythms so that a new idea with the complexity measure is provided to characterize functional dissociation of lower and upper frequency alpha rhythms in relation to hand motor imagery.

Objective:To compare the effect of four different techniques on removal of vapor lock in the apical region of curved root canals.Methods:Forty simulated resin root canals with 45° curvature were prepared using WaveOne Primary,then the apical foramen were sealed with soft wax.The teeth were divided randomly into 4 groups thereafter (n =10).Contract solution was injected into the canals using a 30 G side-vented needle and scanned with cone-beam CT (CBCT) to identify the volume of the vapor lock.Four different techniques including photon-induced photoacoustic streaming (PIPS) laser-activated irrigation,gutta-percha cone technique,ultrasonic irrigation,and sonic irrigation were used to remove the vapor locks in the root canals.The residual volume of the vapor lock was identified again using CBCT scanning data.Accordingly,the reduction rates of the vapor lock were calculated.Furthermore,the initial and residual vapor lock length was calculated.The data were analyzed by using the One-Way ANOVA analysis and Kruskal-Wallis H test at a significance level of P ＜ 0.05.Results:There was no significant difference in the initial vapor lock volume (P ＞ 0.05).Residual volume of the vapor lock for PIPS laser-activated irrigation was 0 mm3,and that for gutta-percha cone technique was (0.02 ± 0.07) mm3,significantly lower than those of ultrasonic and sonic irrigation,the values being (0.20 ± 0.09)mm3 and (0.23 ±0.06) mm3 (P ＜0.001),respectively.The reduction rates of the vapor lock of PIPS laser-activated irrigation and gutta-percha cone technique were 100.00％ (100.00％,100.00％) and 100.00％ (77.66％,100.00％),respectively,significantly higher than those of ultrasonic irrigation [70.37％ (56.41％,91.43％)] and sonic irrigation [63.54％ (51.47％,74.00％),P ＜0.001].The length of the residual vapor lock for PIPS laser-activated irrigation was 0 mm,and that for gutta-percha cone technique was (0.15 ±0.47) mm,significantly lower than those of ultrasonic and sonic irrigation,values being (2.21 ±0.09) mm and (2.34 ±0.08) mm (P ＜0.001),respectively.The length of the residual vapor locks in the ultrasonic and sonic group remained approximately the same as the distance between the working tip and the apical foramen.Conclusion:PIPS laser activated irrigation and gutta-percha cone technique could remove the vapor lock from the apical region of curved canals effectivelv.

Objective: To observe the effect of acupuncture-moxibustion on the expression of insulin-like growth factor-1 (IGF-1) and suppressor of cytokine signaling-2 (SOCS2) in colonic mucosa of rat models of ulcerative colitis (UC), and explore the mechanism of acupuncture- moxibustion therapy in treating UC. Methods: The rats were randomized into a normal control (NC) group, a model control (MC) group, an herb-partitioned moxibustion (HPM) group and an electroacupuncture (EA) group, 8 in each group. The rat models of UC were established by immunological methods combined with local stimulation. The rats in the HPM and EA groups were given herb-partitioned moxibustion and electroacupuncture treatments respectively, once every day, lasting for 14 d. The morphological variations of rat's colonic mucosa were observed under light microscope; the colonic mucosal mucin was detected by PAS-AB and HID-AB staining methods; the expression of IGF-1 and SOCS2 was assayed by the immunohistochemical method. Results: In the rat models of UC, ulceration and inflammation of the colon were revealed by light microscope. The concentration of colonic mucosal mucin was reduced (P<0.01), while the expression of IGF-1 had an increase (P<0.01), and the expression of SOCS2 was reduced (P<0.01). After HPM or EA treatment, the pathological injuries of colonic mucosa had improved, the concentration of mucin increased (P<0.01), the expression of IGF-1 decreased (P<0.01), and the expression of SOCS2 increased (P<0.01). Conclusion: The secretion of mucosal mucin in rat UC decreased, the expression of IGF-1 was significantly higher, while the expression of SOCS2 was remarkably lower; both HPM and EA can help improve the damage of colonic mucosa in rat UC, and modulate the secretion of mucin, as well as regulate the expression of IGF-1 and SOCS2 in the colonic mucosa.

OBJECTIVE To explore the absorption mechanism of thiophenorphine, and its effect on P-glycoprotein (P-gp) expression by using Caco-2 cell monolayer model. METHODSThe LC-MS-MS method was applied to determine thiophenorphine concentration in millicell system. The bi-directional permeability studies were performed to investigate the potential involvement of efflux carriers in the intestinal absorption. P-gp inhibition was studied by flow cytometry using calcein-AM as P-gp substrate.The expression of P-gp was evaluated using Western blotting. RESULTSThiophenorphine transport in Caco-2 cells was in time-dependent manner. Its average apparent permeability coefficient (P_(app)) was 2.338×10~(-6) cm·s~(-1). P_(app) was increased 2.8 folds by P-gp inhibitor ciclosporin A, and 2.3 folds by mulitdrug resistance-associated protein2 (MRP2) inhibitor MK571. The accumulation of calcein-AM and the expression of P-gp in Caco-2 cell line wasn't changed noticeably by thiophenorphine. CONCLUSION Thiophenorphine is a common substrate of P-gp and MRP2 and it shows normal transport in millicell system. The expression of P-gp doesn't induce by thiophenorphine.
