Results indicated that within 24 hours after SCI malondialdehyde (MDA) increased progressively, 2 hours after SCI it reached the peak; and the superoxide dismutase (SOD) activity decreased significantly at the same hours, the decrease being the most marked 2-6 hours after SCI.

Rats in the EA groups were treated for20 min, once daily for 7 days. The mechanical withdrawal threshold was evaluated at 1 day preoperatively and at 3, 5, and 7 days postoperatively. At 7days postoperatively, hematoxylin-eosin(HE) staining was used to investigate spinal morphological changes. Spinal EP2 messenger ribonucleic acid(m RNA) was detected using reverse-transcription polymerase chain reaction.RESULTS: After the EA treatment, the mechanical withdrawal threshold was up-regulated compared with the model group(P < 0.05). The expression of EP2 m RNA was up-regulated in the spinal cord on day 7 after surgery(P < 0.05). EA stimulation tended to down-regulate EP2 m RNA expression compared with the model group(P > 0.05). The EA 1and EA 2 groups showed a larger treatment effect than the EA 3 group. The HE results showed that EA can improve spinal histomorphology induced by neuropathic pain.CONCLUSION: EA had a strong analgesic and anti-inflammatory effect. The therapeutic effect of EA on the down-regulation of spinal EP2 m RNA expression may be greater when either local acupoints or a distal-proximal combination of acupoints are used than when distal points are used.展开更多

De Qi comprises needling sensations felt by the patient, and the sensations perceived by the acupuncturist. Classical Traditional Chinese Medicine theory states that De Qi is closely related to curative effect.In modern studies, the main index that researchers have used to evaluate De Qi was the needling sensation reported by the patient. Between 1 st Aug and 31 st Oct 2014, we conducted an electronic database search of all fields in Chinese and English to select literature assessing acupuncture needle sensations. We then reviewed the methods used within these studies to evaluate De Qi. The methods included simple evaluation, and the use of a De Qi scale/questionnaire. The simple evaluation, a qualitative evaluation, was judged by typical sensations felt by the patient after needling at acupoints, such as soreness, numbness, fullness, and heaviness.This method was easy and practicable, and had been adopted widely by Chinese researchers. In contrast, the De Qi scale/questionnaire, a quantitative evaluation, had multiple compiling methods available for evaluating the intensity of De Qi. The standardization and objectification of the De Qi scale/questionnaire effectively improved the quality of studies on De Qi, thereby these scales/questionnaires have been acknowledged and applied by most researchers. The present review analyzed and compared the scales/questionnaires used to evaluate De Qi; furthermore, we provided suggestions for the development and improvement of these questionnaires through integration with classical De Qi theory.展开更多

METHODS: Ninety patients undergoing IVF-EF oocyte retrieval were randomly divided into three groups: an acupuncture group with needles inserted into bilateral Hegu (LI 4) points, a placebo group given placebo needles, and a control group with routine oocyte retrieval. Each group had an indometacin enema 30 min before the operation. We compared the pain-rated index (PRI), visual analogy scale (VAS), and present pain intensity (PPI) immediately after operation and 1 h after operation. We also determined the neuropeptide Y (NPY) level of the follicular fluid. RESULTS: PRI, VAS, and PPI after operation and 1 hafter operation in the acupuncture group were significantly lower than those in the control group (P< 0.01). No obvious difference (P>0.05) was observed in PRI,VAS, and PPI after operation and 1 h after operation between the placebo group and the control group.The NPY level of the follicular fluid in the acupuncture group was significantly higher than that in the control group (P<0.01). No obvious difference (P>0.05) was observed in the NPY level of the follicular fluid between the placebo group and the control group. CONCLUSION: The analgesic effect of acupuncture at Hegu in transvaginal oocyte retrieval using ultrasonography may be related to the increase in the NPY level of the follicular fluid.展开更多

By cryodesiccation technology in combination with the control of its quality and stability, the optimal formulation and preparation route were screened. Through small-scale and pilot-scale production validation, the formulation and preparation route were confirmed, in which mannitol was used as skeletal matter, meglumine was used as solubilizer and p H stabilizer, and sodium hydroxide was used as p H regulator. The formulation and preparation route were reasonable, showing good quality control and stability and fitting the pharmaceutical and clinical need.展开更多
