An internal amplification control, which could be co-amplified with the invA target gene of Salmonella in the PCR system, was constructed in order to indicate possible PCR inhibitors derived from food samples. Specificity of this PCR system was tested with 9 Salmonella strains and 15 non-Salmonella strains, and the results showed that there was a 374 bp amplicon resulted from all Salmonella strains, while only a 513 bp IAC amplicon appeared after the amplification for all non-Salmonella strains. The detection sensitivity of this PCR system was 12.8 fg/?L for purified target DNA, and the detection limit for artificially inoculated milks was 8 cfu /25g if they were enriched for 8h in buffered peptone water. Salmonella in 80 samples of seriously contaminated milks was detected by the PCR method developed in this study, and the experiments demonstrated that it could successfully eliminate false-negative results.

OBJECTIVETo observe and evaluate the clinical effect of acupuncture at "Siguan" combined with the Gallbladder Meridian acupoints on migraine.
METHODSWith randomized controlled trial design, 87 patients were randomly divided into an observation group (42 cases) and a control group (45 cases). The observation group was treated with acupuncture at "Siguan" including Hegu (LI 4) and Taichong (LR 3), combined with the Gallbladder Meridian acupoints including Fengchi (GB 20), Shuaigu (GB 8), Qiuxu (GB 40) and Zulinqi (GB 41), while the control group was treated with acupuncture at the Gallbladder Meridian acupoints, including Fengchi (GB 20), Shuaigu (GB 8), Qiuxu (GB 40), Zulinqi (GB 41), Yanglingquan (GB 34) and Hanyan (GB 4). The treatment was given every other day in two groups, 3 times per week for totally 6 weeks. The migraine intensity, migraine frequency and lasting time of each migraine were observed before and after treatment, and 3-month follow-up was performed after treatment. The clinical efficacy in two groups was evaluated.
RESULTSCompared with those before treatment, the migraine intensity, frequency and lasting time were all reduced significantly after treatment in the two groups (all P<0.01), which were more obvious in the observation group (all P<0.05). At the end of the treatment, the total effective rate was 95.2% (40/42) in the observation group and 80.0% (36/45) in the control group, which had statistical difference (P<0.05). After 3-month follow-up, the total effective rate was 88.1% (37/42) in the observation group and 75.6% (34/45) in the control group, which had no statistical difference (P>0.05).
CONCLUSIONThe "Siguan" combined with the Gallbladder Meridian acupoints could significantly relieve the migraine intensity, frequency and lasting time, and its improvement of symptoms and short-term efficacy are superior to those of the Gallbladder Meridian acupoints alone.

OBJECTIVETo explore protective effects of acupuncture at "Zusanli" (ST 36) on cerebral tissue in rats with sepsis.
METHODSCecal ligation and puncture (CLP) was applied to duplicate the rat model of sepsis. According to random number table, thirty SD rats were divided into a sepsis model group (group A), a sepsis model plus electroacupuncture (EA) group (group B), and a sepsis model plus non-acupoint EA group (group C), ten rats in each one. EA with the same frequency and intensity at "Zusanli" (ST 36) and non-acupoint (0.5 cm laterally to "Zusanli") for 30 min was applied in the group B and group C, respectively. No treatment was given in the goup A. 6 hours after CLP, blood was acquired from abdominal aorta to measure the levels of neuron specific enolase (NSE). Then the rats were sacrificed by abdominal aorta exsanguination to take their cerebral tissue for measuring the levels of tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6).
RESULTSSix hours after CLP, the level of NSE was (3.51 +/- 0.39) ng/mL in group B, which was significantly lower than (7.72 +/- 0.64) ng/mL in group A (P<0.05). The level of NSE was (8.02 +/- 0.72) ng/mL in the group C, which had no statistical significance with group A (P>0.05). The levels of TNF-alpha, IL-6 in cerebral tissue in group B were significantly lower than that of group A and C (all P>0.05).
CONCLUSIONEA at "Zusanli" (ST 36) has certain protective effect on septic rat's brain, which has some relationship with decreasing levels of cerebral tissue proinflammatory cytokine and plasma NSE. EA at non-acupoint has no the same action.

Objective To investigate the genetic association between mutation in cytochrome P450 1A2 (CYP1A2) gene and Erxian suop response. Methods Forty-eight patients with male climacteric syndrome of both Yin and Yang deficiency received a treatment of erxian suop with three months. The severity of symptoms and responses to Erxian suop were quantizated by the method of Department of Psychology in Istanbul Bosphorus University and Clinical Research Guidance Principle on New Drug of Traditional Chinese Medicine published by China. A single nucleotide polymorphism (SNP) at position 2964 (G-A) of CYP1A2 gene were identified by polymerase chain reaction (PCR) in order to analyse the relationship between Erxian response and CYP1A2 single nucleotide polymorphism. Results Statistical analysis showed there was no significant difference among genetype and genetype distribution of CYP1A2 G2964A between the patients and control group. The genotype of the 16 patients among 32 effective patients was G/G (56.25%). The genotype of the 11 patients among 16 ineffective patients was G/A (68.75%). There was no significant difference in symptoms, physical sign between the two groups at the pre-treat and post-treat. Also the two groups had no significant difference among the score of major symptoms and hyposymptoms. Conclusion The patients with genotype of G/G have higher efficiency, while with genotype of G/A have lower efficiency among patients with CYP1A2 G2964A gene when treated with erxian soup.

OBJECTIVETo evaluate the efficacy and safety of Yigan Fupi Decoction (YFD) in the treatment of irritable bowel syndrome with diarrhea (IBS-D) patients.
METHODSA randomized controlled clinical trail was carried out in patients with IBS-D. All patients were randomly assigned to the treatment group (58 cases, treated with YFD) and the control group (58 cases, treated with Pinaverium Bromide Tablet). The treatment course was 4 weeks for all patients. The total effective rate, the stool property and state, the quality of life (QOL), and TCM syndrome efficacy were assessed by IBS bowel symptom severity scale (IBS-BSS), IBS defecation state questionnaire (IBS-DSQ), IBS quality of life questionnaire (IBS-QOL), and traditional Chinese medicine pattern curative effect scoring system (TCM-PES) before and after treatment.
RESULTSThere was no statistical difference in the total effective rate between the two groups (82.76% vs. 77.59%, P > 0.05). The treatment group was superior in the total IBS-BSS integral to the control group (P < 0.05). The total effective rate of improving the stool property was better in the treatment group than in the control group (81.03% vs. 72.41%, P < 0.05). Besides, the number of days for emergent defecation among 10 days was less in the treatment group than in the control group (P < 0.05). The improvement of the total IBS-QOL integral and the total integral of TCM syndrome were better in the treatment group than in the control group (P < 0.01). The total effective rate of TCM-PES was better in the treatment group than in the control group (84.48% vs. 70.69%, P < 0.05).
CONCLUSIONYFD was effective in the treatment of IBS-D patients of Gan-qi invading Pi syndrome, and could effectively relieve bowel symptoms, improve the stool property and the defecation frequency, elevate their QOL, and attenuate Gan-qi invading Pi syndrome with favorable safety and compliance.

OBJECTIVETo evaluate the short-term and long-term effects on treatment of neck pain caused by cervical spondylosis with the combination of acupuncture and moxibustion with seed-size moxa cone.
METHODSOne hundred and forty-five patients of neck pain were randomly divided into an acupuncture-moxibustion group (49 cases), an acupuncture group (48 cases) and a moxibustion group (48 cases). Acupoints of Bailao (Extra), Dazhui (GV 14), Jianzhongshu (SI15) and Zhongzhu (TE 3) were adopted for all the 3 groups. Acupuncture was applied at all the acupoints with 20 min needling retention for the acupuncture group. Moxibustion with seed-size moxa cone was used with 5 cones on each point for the moxibustion group. And both acupuncture and moxibustion with seed-size moxa cone were adopted for the acupuncture-moxibustion group. The treatment was applied once every 3 days, and 10 treatments should be finished within 4 weeks. Follow-up should be carried out for 3 months. The short-term and long-term effects were evaluated with the scores of Northwick Park Pain Questionnaire (NPQ) and McGill Pain Questionnaire (MPQ) as the indices of therapeutic effect.
RESULTSThe NPQ score and MPQ score of all the 3 groups after the treating course and the 3-month follow-up were both decreased when compared with those before the treatment (all P<0. 05). The scores of NPQ and MPQ the acupuncture-moxibustion group were lower than that of the other two groups. And the difference had obvious significance (P<0. 05). High efficiency of pain relieving for cervical spondylosis could be found in all the 3 groups, which showed that short-term and long-term effects were good for all the 3 groups. And the highest curative effect could be found in acupuncture-moxibustion group.
CONCLUSIONCombination of acupuncture and moxibustion with seed-size moxa cone has reached a superior effect in short-term and long-term for neck pain caused by cervical spondylosis.
