Objective To investigate the clinical efficacy of herbal cake moxibustion in treating chronic renal failure. 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.

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] The study analyzes the current situation of public’s satisfaction and expectation on the grass-roots’work of TCM in our province to make advice on improvement. [Method] From the perspective of service objects, combining with satisfaction theory and using the method of random surveys, the article does the researches on the publics’satisfactions and expectations on 24 projects related to the grass-roots levels of TCM and puts forward corresponding countermeasure against those problems. [Consequence] The degree of satisfaction ranges from 65 to 72, average is 68.685; the highest degree of satisfaction is the therapeutic effects of TCM, but the lowest one is medical costs. The degree of expectation ranges from 79~86, average is 83.931, the highest degree of satisfaction is diagnostic reference level of medical staff from the grass-roots ’work of TCM, the lowest one is characteristic service projects of TCM. [Conclusion] The study analyzes and evaluates the grass-roots ’work of TCM by the related theory of satisfaction, having significant meaning on improving the management services’level of the grass-roots’work and the performance evaluation of government.

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 evaluate effect of the morphology of simulated S-shaped root canals with Reciproc or Mtwo instruments on root canal irrigation. Methods: A total of 40 simulated S-shaped resin blocks were randomly divided into 2 groups (n=20), which was prepared by Reciproc or Mtwo. Blue ink was injected with constant speed and volume into the canals using 30G lateral opening syringe. hTe distance from needle tip to apex and vapor lock length were measured. A type of 25# 0.04 gutta-percha point was used to stir and remove the vapor lock. hTe time for removal of the vapor lock was recorded. Another syringe was used to inject saline into the canals and to measure the length of stagnant water. Results: hTe distance from needle tip to apex in the Reciproc group was signiifcantly longer than that in the Mtwo group [(4.276 ± 0.221) mm vs (3.459 ± 0.205) mm,P<0.05]. The vapor lock length in the Reciproc group was signiifcantly longer than that in the Mtwo group [(4.472 ± 0.230) mm vs (3.668±0.217) mm,P<0.05]. hTe time to remove vapor lock was signiifcantly shorter in the Reciproc group than that in the Mtwo group [(10.13 ± 1.79) s vs (15.29 ± 2.15) s,P<0.05]. The length of stagnant water was also shorter in the Reciproc group than that in the Mtwo group[(1.351 ± 0.142) mm vs (2.245 ± 0.206) mm,P<0.05]. Conclusion: hTe morphology of S-shaped root canal affects the root canal irrigation. hTe effect of root canal irrigated by Reciproc is better than that by Mtwo.

OBJECTIVE To investigate the profile of pathogen of infection in kidney disease patients. METHODS Pathogen of infection in kidney disease patients in our hospital from Jan 2004 to Feb 2006 was retrospectively investigated. RESULTS A total of 240 pathogen strains were isolated from 223 cases.Of the 240 isolated strains the rate of strains of Gram-negative bacilli was 55.4%,that of the Gram-positive cocci was 26.3%,the rate of fungi was 10.0% and that of the Gram-positive bacilli was 8.3%.The positive rate of Escherichia coli was the highest followed by Haemophilus influenzae.54.2% Of isolates were from urine,21.3% from sputum.The isolated pathogens resisted at different degrees to antibiotics which were used frequently in clinic.The rate of polyinfection was not high. CONCLUSIONS Pathogen of infection in kidney disease patients is mainly Enterobacteriaceae.The isolates mainly are E.coli which is multi-resistant.It mainly causes the urinary infections.
