In order to optimize acupuncture protocol for stephenipodia after stroke, related papers of the recent 20 years are retrieved. Interrelated factors which may influence the therapeutic effect of acupuncture are analyzed through the aspects such as acupoints, needling methods and opportunities of acupuncture. It is held that importance should be attached on relation between acupoints and anatomy during acupoint selection. Different acupuncture protocol can be adopted in different phases of stephenipodia according to its time of occurrence. And it is found that the combination of acupuncture and rehabilitation can reinforce the therapeutic effect. Relationship between effect of acupuncture and patient's condition, acupoint selection and prescription, acupuncture manipulations (including directions, angles, reinforcing and reducing, quantity of stimulus) are worth to be further studied. On the base of the above all mentioned studies, optimization can be carried out on selection of acupoints and acupuncture manipulations. And therapeutic effect can be enhanced when the optimized acupuncture protocol is combined with rehabilitation therapies.

A method for simultaneous determination of 12 kinds of chlorinated disinfection byproducts (DBPs) in drinking water was developed based on liquid-liquid extraction gas chromatography equipped with electron capture detector (GC/ECD).The procedural standard calibration was adopted to eliminate the interference of different matrix.The method detection limits for 12 DBPs were 0.08-0.21 μg/L and the entire analytical procedure was finished in 21.50 min.The recoveries were in the range of 80.9%-115.7% and the relative standard deviations (RSD) were between 0.9% and 9.9% at different concentration levels (5 and 50 μg/L) in tap water and surface water.The correlation coefficients for all 12 kinds of DBPs were greater than 0.99 in the linearity range of 0.5-200 μg/L.The method was applied to determine DBPs in drinking water and source water.This method was rapid and competent for detection of volatile DBPs in drinking water.

OBJECTIVETo observe the clinical efficacy and safety on moderate and severe persistent allergic rhinitis treated with acupuncture.

METHODSSixty-six patients of moderate and severe persistent allergic rhinitis were randomized into an acupuncture group (34 cases) and a western medication group (32 cases). In the acupuncture, group, acupuncture was applied to Dazhui (GV 14), Feishu (BL 13), Pishu (BL 20), Ganshu (BL 18) and Shenshu (BL 23) in the prone, retained for 20 min; then in the supine, at Baihui (GV 20), Yintang (GV 29), yingxiang (LI20) Taichong (LR 3) and Hegu (LI 4), retained for 20 min. Acupuncture was given once every two days, three times a week, continuously for 8 weeks. In the western medication group, cetirizine hydrochloride was taken orally, 10 mg each time, once every day, continuously for 8 weeks. Separately, before treatment, after the treatment of 1 and 2 months and in 1 month after treatment, the total nasal symptom score (TNSS), the scores in the emotion rating scale for Ganzangxiang of TCM (ERSG) and the rhinoconjunctivitis quality of life questionnaire (RQLQ) were observed in the patients of the two groups. The clinical efficacy was compared between the two groups.

RESULTS(1) For TNSS, the results after 1 and 2 months treatment and in 1 month after treatment were all, reduced as compare with that before treatment separately in the two groups (P < 0.05, P < 0.01) The result after 2 months treatment was lower than that after 1 month treatment in the acupuncture group (P < 0.05). In 1 month after treatment, the result in the acupuncture group was lower than that in the western medication group (P < 0.05). (2) For ERSG, the score after 2 months treatment was lower than that before treatment in the two groups (both P < 0.05). The score after 2 months treatment in the acupuncture group was lower than that in the western medication group (P < 0.05). (3) For RQLQ, the score after 1 month treatment was lower than that before treatment and the score after 2 months treatment was lower than that after 1 month treatment in the two groups (all P < 0.05). The score after 1 and 2 months treatment and in 1 month after treatment in the acupuncture group was lower than that in the western medication group separately (all P < 0.05). (4) The total effective rate was 91.2% (31/34) in the acupuncture group and was 90.6% (29/32) in the western medication group, without significant difference between the two groups (P > 0.05).

CONCLUSIONAcupuncture is the safe and effective intervention on moderate and severe persistent allergic rhinitis. Compared with the western medicine group, the efficacy in the acupuncture group presents much more advantageous at its durability.

OBJECTIVETo observe the improvements in constipation differentiated as intestine system syndrome and lung system syndrome treated with electroacupuncture (EA) and explore their correlation.

METHODSSeventy cases of severe functional constipation were randomized into an EA group and a pseudo-EA group, 35 cases in each one. In the EA group, the needles were inserted deeply at Tianshu (ST 25) and Fujie (SP 14) on bilateral sides, and directly went to parietal peritoneum. EA was attached to the needles, dense-disperse wave, 2 Hz/15 Hz, and 0.1 to 1.0 mA. The perpendicular insertion was done at Shangjuxu (ST 37), 25 mm in depth. After qi arrival, the needle was lifted, thrusted and rotated once every 10 min, for 3 times totally. The needles were retained for 30 min. In the pseudo-EA group, the pseudo-points lateral to Tianshu (ST 25), Fujie (SP 14) and Shangjuxu (ST 37) on bilateral sides were punctured shallowly. The electric stimulation was pretended to connect but with the electric wire cutting off. The needles were retained for 30 min. The treatment was given 5 times weekly in the first two weeks and 3 times weekly in the later 6 weeks. Totally, 28 treatments were required. TCM intestine and lung syndrome scale was used for evaluation. The changes in TCM syndromes were observed before and after treatment in the patients of the two groups.

RESULTSThe total score of intestine and lung syndrome and the score of individual syndrome were all reduced after treatment as compared with those before treatment in the two groups (both P<0.01). The improvements of the EA group in the total score of intestine system syndrome, the scores of large. intestine syndrome and stomach syndrome, the total score of lung system syndrome and the score of lung dysfunction in dispersing and descending syndrome were superior to those of the pseudo-EA group (P<0.01, P<0.05). The differences in the scores of lung qi deficiency syndrome and throat syndrome were not significant between the two groups (all P>0.05). Simultaneously, the very strong positive correlation (P<0.01) and positive linear correlation (P<0.01) were presented in the total score of intestine and lung syndrome of the two groups.

CONCLUSIONEA obviously improves in intestine system syndrome (including large intestine syndrome and stomach syndrome), as well as lung system syndrome (lung dysfunction in dispersing and descending) in the treatment of constipation. But the improvements are not apparent in the treatment of lung qi deficiency and throat disorder. Additionally, the obvious correlation is displayed in the improvements in intestine and lung syndrome.

Aim To investigate the effects and possible mechanisms of kaemperol in the rats with chronic cere-bral ischemia.Methods Chronic cerebral hypoperfu-sion model was produced by permanent occlusion of bi-lateral common carotid arteries (2VO)in rats.After KAE treatment,the rats underwent Morris water maze and prehensile traction test.Neuronal morphology was observed using Nissl and HE staining.The activity of SOD and the content of MDA in brain tissue were de-termined.The DJ-1 protein expression was assayed by Western blot.Results Compared with 2VO model group,KAE significantly improved learning and memo-ry and the grasping ability.In addition,KAE signifi-cantly reduced brain tissue pathological injury induced by 2VO. Furthermore, KAE significantly increased SOD activity and enhanced antioxidant protein DJ-1 ex-pression in brain tissue.Conclusions KAE could sig-nificantly attenuate the cognitive impairment,limb bal-ance dysfunction and pathological injury in rats with chronic cerebral ischemia.The mechanism may be re-lated to improving the antioxidant system in vivo.
