Blinding is an important means to control and reduce measurement bias in clinical research， and blinding assessment is the main method to measure the success of the blinding method. By summarizing the current situation of blinding assessment in randomized controlled trials （RCT） of acupuncture， it was found that the report rate of blinding assessment by acupuncture RCT was relatively low， and the studies reporting blinding assessment had several problems， such as incomplete assessment individuals， unreasonable assessment questionnaires， and unscientific analysis methods， and the setting of the assessment time point is controversial. Given the above problems， this paper discussed the key elements of blinding assessment individuals， assessment questionnaires， assessment time points， and analysis methods. It is suggested that blinding assessment should be carried out on all blinded participants and personnel in the study； the assessment questionnaire should be designed by direct inquiry， with responses designed using three or more categorical options that include an "unclear" option； the early stage of the trial should be taken as the mandatory time point for assessment， integrating the evaluation index of the James blinding index and the Bang blinding index， in order to standardize the application of blinding assessment in acupuncture RCT and improve the quality of acupuncture clinical research.

To investigate the effects of ()infection on autonomic nervous function and calcitonin gene-related peptide in patients with functional dyspepsia(FD). Thirty-one patients with FD matching Rome Ⅳ criteria were included and divided into -positive group and -negative group.All patients were evaluated by Symptom Index of Dyspepsia(SID),Nepean Dyspepsia Index(NDI),and Hospital Anxiety and Depression Scale(HADS).Their heart rate variability(HRV)and calcitonin gene-related peptide(CGRP)level were also measured. There were no significant differences in SID(=-0.858, =0.858),NDI(=-1.464, =0.143),and Hospital Depression Scale score(=0.699, =0.485).However,the Hospital Anxiety Scale score was significantly higher in -positive group than the -negative group(=-2.470, =0.014).The level of CGRP in -positive group[(0.999±0.274)ng/ml]was significantly higher than that in the -negative group[(0.812±0.172)ng/ml;=2.238, =0.033].HRV data showed no significant difference between these two groups at very low frequency(=-1.210, =0.236),low frequency(LF)(=0.419, =0.678),high frequency(HF)(=0.612, =0.546),LF/HF(=-0.882, =0.399),and total power(=-0.963, =0.344). In FD patients,patients with -positive FD patients have higher depression and CGRP levels than those without infection,although their dyspepsia symptoms and HRV show no notable changes.

OBJECTIVETo discuss the effects on detrusor hyperreflexia treated with ginger-salt-isolated moxibustion at "Shenque" (CV 8) and its mechanism.

METHODSThirty female adult SD rats were selected. The model of detrusor hyperreflexia was prepared with complete spinal transection at T, of which, 20 rats were randomized into a model group (10 rats) and a moxibustion group (10 rats). A sham-operation group (10 rats) was set up for sham-spinal transection. In the moxibustion group, when urine incontinence occurred (about in 2 weeks of modeling), the ginger-salt-isolated moxibustion at "Shenque" (CV 8) was given, 3 moxa cones each time, once a day, continuously for 7 days. After treatment, in each group, the urodynamic parameters were determined, after which, the bladder detrusor was collected. Western blot was used to determine the protein expressions of M2 and M3 receptors.

RESULTSCompared with the sham-operation group, the micturition interval was shortened apparently (<0.01); the maximal bladder pressure was increased apparently (<0.01); the protein expression of M2 receptor in the detrusor was increased significantly (<0.05) and that of M3 receptor had no apparent change (>0.05) in the rats of the model group. Compared with the model group, the micturition interval was longer apparently (<0.01), the maximal bladder pressure was reduced apparently (<0.01), the protein expression of M2 receptor in the detrusor was reduced significantly (<0.05) and that of M3 receptor had no apparent change (>0.05) in the rats of the moxibustion group.Compared with the sham-operation group, the results of the above indicators were not different significantly in the moxibustion group (all>0.05).

CONCLUSIONSThe ginger-salt-isolated moxibustion at "Shenque" (CV 8) suppresses the overactive bladder in the rat with spinal transection and its effect mechanism is possibly relevant with reducing the protein expression of detrusor M2 and inhibiting the excessive contraction of the detrusor.

Even though a large amount of researches showing the clinical effectiveness of acupuncture, there are the researches indicating the absent difference between acupuncture and sham-acupuncture (placebo), which provides the doubts on the specificity of acupuncture. It may be considered that acupuncture intervention is complica-ted and may produce unique non-specific effect, which results in the failure to evaluate effectively the acupuncture efficacy. The influential factors of the non-specific effect of acupuncture include the interaction between physician and patient, expectancy, physician authority, acupuncture treatment experiences, etc. It may be also relevant with the anticipated biological effect, Hawthorne effect, Pavlovian conditioned reflex, etc.

This article summarized clinical studies and mechanism research literature on acupuncture in treating chemotherapy induced nausea and vomiting in the latest 20 years. It found that the domestic and foreign researches tend to regard acupuncture as an effective method for the treatment of chemotherapy induced nausea and vomiting, which still requires further high-level clinical researches to verify. Acupuncture may prevent and treat chemotherapy induced nausea and vomiting through multiple mechanisms, and studies on these mechanisms show extensive research prospect.

Objective To compare the cumulative analgesic effects of electroacupuncture at Sanyinjiao (SP6), Xuanzhong (GB39) and non-acupoint in treating primary dysmenorrhea. Method By adopting a multi-centered randomized controlled study method, 501 patients recruited from Dongzhimen Hospital of Beijing University of Chinese Medicine, China-Japan Friendship Hospital, Beijing Hospital of Traditional Chinese Medicine of Capital Medical University, First Teaching Hospital of Tianjin University of Traditional Chinese Medicine, Huguosi Hospital of Chinese Medicine of Beijing University of Chinese Medicine and the Outpatient of Shandong University of Traditional Chinese Medicine were randomized into a Sanyinjiao group, a Xuanzhong group, and a non-acupoint group, 167 subjects in each group. The electroacupuncture intervention was applied when dysmenorrhea flared up and the Visual Analogue Scale (VAS) ≥40 mm, with frequency at 2/100 Hz and intensity during patient’s endurance, 30 min each time, once a day, and for successive 3 d. Before the first treatment, 30 min after the first treatment, and respectively prior to the second and third treatment, VAS was used to measure the pain intensity. Meanwhile, the Retrospective Symptom Scale (RSS-COX 2) was investigated before the first treatment, right after the removal of needles for the first treatment, before the second and third treatment. Result The decrease of VAS in Sanyinjiao group was more significant than that in Xuanzhong group and non-acupoint group (MD=﹣2.92 mm, P=0.028; MD=﹣3.47 mm, P=0.009), while there was no significant difference between Xuanzhong group and non-acupoint group (MD=﹣0.56 mm, P=0.674); there were no significant differences in comparing the RSS-COX2 total score among the three groups (P=0.086). Conclusion Sanyinjiao (SP6) can produce a more significant cumulative analgesic effect for primary dysmenorrhea patient than Xuanzhong and non-acupoint, and the effects of Xuanzhong and non-acupoit are equivalent.

Objective To observe the effect of oxidized low-density lipoproteins (Ox-LDL),15-Deoxy-△ 12,14-prostaglandin J2 ( 15d-PGJ2 ),leukotrienes B4 ( LTB4 ) on mRNA expressions of peroxisome proliferator activated receptor γ2 ( PPARγ2 ),receptor activator of NF-κB ligand (RANKL),alkaline phosphatase ( ALP),and osteoprotegerin(OPG) in osteoblastic cells of rats; and to investigate the influence of these PPARγ2 endogenous ligands on bone metabolism.Methods Rat osteoblastic cells were cultured in vitro for 24 h in medium with different PPARγ2 endogenous ligands at various concentrations ( the final concentrations of Ox-LDL were 0,12.5,25,50μg/ml; the final concentrations of 15 d-PGJ2 were 0,10,20,30 μmol/L; the final concentrations of LTB4 were 0,0.1,1.0,10 μ mol/L).RT-PCR was performed to determine the mRNA expressions of PPARγ2,RANKL,ALP,and OPG in osteoblastic cells.Results RT-PCR analysis showed that Ox-LDL,15d-PGJ2,and LTB4 all down-regulated the mRNA expressions of RANKL,ALP,and OPG,while up-regulated the mRNA expressions of PPARγ2 in osteoblastic cells in a dose-dependent manner.Significant differences were found in interclass comparisons( P＜0.05 or P＜ 0.01 ).Conclusions These findings suggest that Ox-LDL,15d-PGJ2,and LTB4 suppress the expressions of osteogenic genes through activating the transcription activity of PPARγ2,and this may be a plausible mechanism of senile osteoporosis.

Objective To study the effect of pioglitazone on the differentiation and function of rat osteoclast-like cells (OLC), and to probe the relationship between activated PPARγ2 and osteoclasts. Methods On day 1 of OLC formation from nonadherent bone marrow ceils (BMC) obtained from rats induced by M-CSF and receptor activator of NF-кB ligand (RANKL), 1, 5 and 10μmol/L pioglitazone hydrochloride was added. RT- PCR was performed to determine the mRNA expressions of PPARγ2 and receptor activator of NF-кB (RANK) on day 3, 5 and 7 during incubation, the number of tartrate-resistant acid phosphatase (TRAP)-positive cells,the number of bone resorption pits and the ratio of its area on dentin slice were counted, the activity of TRAP and the mean fluorescence intensity of integrin β3 (CD61) of OLC were also measured. Results (1) The effect on the differentiation of OLC: The addition of pioglitazone at the start of the culture period induced a dose-dependent decrease in TRAP-positive OLC and the activity of TRAP (P < 0.01 or P < 0.05) ; the mRNA expression of PPARγ2 was up-regulated by 5 and 10 μmol/L pioglitazone in the early stage of incubation and attenuated with thematuration of OLC on the contrary, however, the expression of RANK was down-regulated by 5 and 10 μmol/L piolitazone in every stage of incubation (P < 0.05 or P < 0.01), combined with decrease in TRAP-positive OLC from day 3 by 10 μmol/L pioglitazone. (2) The effect on the function of OLC: the number of bone resorption pits and the ratio of its area on dentin slice were decreased in groups of 5 and 10 μmol/L pioglitazone (P < 0.01 orP < 0.05), no obvious change was noted in the group with 1 μmol/L pioglitazone compared with the control group; the mean fluorescence intensity of CD61 were down-regulated in groups of 5 and 10 μmol/L pioglitazone (P < 0.05 or P <0.01). Conclusion Activation of PPARγ2 pathway by pioglitazone could partially inhibit differentiation and function of OLC derived from rat BMC.
