OBJECTIVETo observe differences of clinical therapeutic effects between deep-oblique acupuncture with long needle and regular perpendicular acupuncture at Guanyuan (CV 4) for urinary retention to explore standard acupuncture method in clinic.

METHODSOne hundred and thirty-two cases of urinary retention were randomly divided into an observation group (78 cases) and a control group (54 cases). Needles with 75 mm in length were deeply and obliquely inserted into Guanyuan (CV 4) in the observation group while needles with 40 mm in length were perpendicularly inserted. Clinical therapeutic effects in two groups were observed.

RESULTSAfter treatment the total effective rate was 80.8% (63/78) in the observation group and 57.4% (31/54) in the control group, which had significant difference between two groups (P<0.05). The curative effect of postpartum retention of urine was obviously superior to that of postoperative and prostate-induced urinary retention in the ebservation group, and the effect of urinary retention due to different etiology in the observation was also superior to that in the control group in the ebservation group [in the observation group total effective rate was 88.6% (47/53) in postpartum retention of urine, 50.0% (3/6) in prostate-induced urinary retention and 68.4% (13/19) in orthopedic postoperative retention of urine while in the control group total effective rate was 69.4% (25/36) in postpartum retention of urine, 20.0% (1/5) in prostate-induced urinary retention and 38.5% (5/13) in orthopedic postoperative retention of urine)].

CONCLUSIONThe deep-oblique acupuncture with long needle at Guanyuan (CV 4) has significant curative effect on urinary retention in clinic, especially for patients with postpartum urinary retention, which could be taken as standard acupuncture method.

Objective To observe pathological process of intestinal epithelial cells subjected to ischemia,ischemia/reperfusion injury and inflammation simulated hypoxia/reoxygenation (H/R) and lipopolysaccharide (LPS) challenged human fetal normal colonic cell (FHC) line in vivo,and to observe the changes when the assaulted intestinal epithelial cells were treated with emodin,in order to explore the possible intervention targets of emodin.Methods Normoxia group:the FHC cells were cultured in 95％ air and 5％ CO2 at 37 ℃.Hypoxia (H) group:the cells were cultured with a mixed anaerobic gas of 1％ O2,5％ CO2 and 94％ N2 at 37 ℃ for 1,2,3,4 hours.H + LPS group:the cells were cultured in hypoxic condition as H group with simultaneous challenge of LPS (1 mg/L).H/R group:the cells were cultured in hypoxia for 3 hours followed by reoxygenation for 1,2,3 and 4 hours,respectively.H/R + LPS group:the cells were cultured in H/R as H/R group and LPS (1 mg/L) simultaneously.Emodin intervention group:the cells were cultured in H3 h/R2 h + LPS and emodin (20,40,60,80 μmol/L) simultaneously.The variation trends of phosphorylation nuclear factor-κB profilin-o (pIκB-α),phosphorylation NF-κBp65 (pNF-κBp65) and their downstream target gene cyclooxygenase-2 (COX-2),and hypoxia-inducible factor-1α (HIF-1 α) were determined by Western Blot.The morphological changes in intestinal epithelium in different groups were observed using light microscope.The effect of emodin on the proliferation of intestinal epithelial cell was measured by methyl thiazolyl tetrazolium (MTT) assay.Results ① H group:the expressions of pIκB-α,pNF-κBp65 and COX-2 were upregulated,peaking at H1 h (0.350 ± 0.018,1.083 ± 0.054,0.903 ± 0.045),and then they gradually lowered (F value was 3.011,7.247,5.754,P value was 0.013,0.000,0.005,respectively).The expression of HIF-1 α peaked at H3 h (1.511 ± 0.076),but there was no significant difference among different groups (F=1.881,P=0.062).H + LPS group:the expressions of pIκB-α,pNF-κBp65,COX-2,HIF-1α were increased with elongation of duration of hypoxia,and a maximal induction was observed at H3 h (0.504 ± 0.025,1.255 ± 0.063,0.812 ± 0.041,1.209 ± 0.075,F value was 2.683,8.774,9.765,2.432,and P value was 0.011,0.000,0.000,0.026,respectively).H/R group:with the prolonged duration of reoxygenation,the expressions of NF-κB signaling pathway proteins (pIκB-α,pNF-κBp65,COX-2) were decreased and dropped to nadir at H3 h/R4 h (0.712 ± 0.034,1.202 ± 0.048,0.691 ± 0.042,F value was 1.923,6.765,2.719,and P value was 0.063,0.000,0.016,respectively).Compared with H group,HIF-1α was decreased with a prolonged duration of reoxygenation in H/R group,but there was no significant difference in value among different time points (F=1.280,P=0.081).H/R + LPS group:pIκB-o,pNF-κBp65,COX-2,HIF-1α showed no sign of degradation with the prolonged duration of reoxygenation,and their expression increased to maximum analogously at R2-3 h (3.302 ± 0.061,2.315 ± 0.055,2.017 ± 0.043,2.413 ± 0.098,Fvalue was 4.614,1.652,5.970,2.076,and Pvalue was 0.001,0.067,0.000,0.037,respectively).Emodin group:emodin when co-treated with H/R + LPS inhibited the expression of HIF-1o and NF-κB pathways with a dose-effect relationship (P＜0.05 or P＜0.01).Emodin at the dose of 80 μmol/L showed most marked inhibition (2.599 ± 0.130,1.772 ± 0.089,2.590 ± 0.129,2.518 ± 0.125).However,after treatment of emodin did not show such effect.② After treatment with H/R + LPS,there were morphological changes in cells:vacuoles,deformation and fusion.The speed of cell growth became much slower compared with H group.③ Emodin (20-80 μmol/L) had no significant effect on cell proliferation.Although emodin produced biological effect in this concentration range,it had no cellular toxicity.Conclusions Both hypoxia and inflammation can activate the hypoxia pathway of HIF-1α and the pro-inflammatory pathway of NF-κB,but different stimuli cause varying degrees of activation in these two pathways.In H/R group,both pathways were weakened during reoxygenation.However,in H/R + LPS group,the proteins remained to show a relatively high expression during the process of reoxygenation.This may be related to the pathophysiological mechanism of intestinal ischemia/reperfusion injury:hypoxia/reperfusion injury and LPS act together to destroy the intestinal epithelial cells and induce gut-derived sepsis.Emodin may inhibit inflammation by blocking HIF-1α/NF-κB-COX-2 signaling pathways.

Objective To compare 2 methods to immobilize probes on the surface of gold membrane and select the better one for aptamer immobilization of aptamer-based piezoelectric quartz crystal sensor. Methods Anti-IgE aptamers were immobilized on the gold surface of piezoelectric quartz crystal sensor with thiol method or biotin-avidin method. The changes of frequency were compared in reactions with different concentrations of IgE. Results Biotin-avidin method obtained higher frequency changes in the reactions of IgE, lower limit of detection and wider liner range than thiol method. For biotin-avidin method, there was significant linear correlation between frequency changes and the concentration of IgE with the correlation coefficient of 0.994 5. Conclusion The thiol method which is proved effective for probe immobilization on gene sensor is unfit for aptamer immobilization. Biotin-avidin method has a better ability to immobilize probe on the surfaces of aptamer-based piezoelectric quartz crystal sensor.
