ObjectiveTO study the mechanism of xingnao kaiqiao acupuncture for brain occlusion. Methodusing one-side middle cerebral artery occlusion(MCAo)rats by thermoregulation as focal cerebral ischemis experimental animal. The dynamic changes of c-fosprotein in sichemic region of brain tissue were observed by imnunohistochemitry method. Meanwhile the effect of acupuncture was stud-ied. ResultThe outcome of xingnao kaiqiao group was better than that of rourine group. Acupuncture could enhance the expression of c-fosprotein in all stages of ischemia, promote the stress ability of neuron produce adaptive changes to brain sichemia and improve recovery of braintissue. ConclusionThe dffect of xingnao kaiqiao acupuncture was better than that of routine acupuncture.

Lactic acid bacteria (LAB) are traditional dairy strains which have a long history of safe use. They are a kind of food-grade microorganisms that can be used in industry to produce lots of food and drink, such as yoghourt. In the last two decades the physiology and genetics of these bacteria have been thoroughly studied. Because of their genetic accessibility and easy to handle, LAB, in addition to their traditional applications, have been extensively developed and used for the expression of heterologous genes. So they have an important foreground in agricultural, medical and many other fields. People have developed a series of food-grade gene expression systems of LAB. LAB, especially their model strain Lactococcus lactis and their most useful food-grade induced expression system--nisin controlled gene expression system NICE and its food-grade inducer nisin, food-grade host, expressing vectors and applications in expressing heterologous proteins of NICE will be introduced.

Objective To investigate the predictors of deep remission in patients with Crohn′s disease (CD)treated with infliximab.Methods From February 2008 to February 2015 ,the clinical, laboratory and follow up data of 44 CD patients who received infliximab treatment and maintained clinical remission over six months were retrospectively analyzed.Mucosal healing was defined as no ulcer under endoscopy.Deep remission was defined as clinical remission with mucosal healing.According to results of endoscopy examination,the enrolled patients were divided into deep remission group and non-deep remission group.T test or Wilcoxon rank sum test was used for comparison of measurement data between groups,and chi square test was performed for the rate comparison.Multivariate analysis was made with Logistic regression.Results Median age of 44 patients was 19.5 yeares,39 males (88.6%),five females (11 .4%),and the median disease duration was 35 .0 months (18.5 to 73.5 months).Deep remission was achieved in 20 CD patients with long-time follow-up (median follow-up time 19 months,12 to 29 months). The mean duration of achieving deep remission was (28.9 ± 14.3 )weeks.There was no statistically significant difference between 20 patients with deep remission and 24 patients without deep remission in age of onset,disease duration,smoking status,Montreal phenotype,concurrent medications (mesalazine, steroids and azathioprine ), as well as body mass index (BMI ) and laboratory tests (erythrocyte sedimentation rate (ESR),high-sensitivity C-reactive protein (hsCRP),hemoglobin (Hb)and platelet (PLT)count)before administrating.The results of Logistic regression demonstrated that extraintestinal manifestations (arthralgia)(odds ratio (OR)=29.9,95 % confidence interval (CI )1 .26 -714.20,P =0.036),normalization of hs CRP at 14 th week after induced remission (OR=0.88,95 %CI 0.78-0.99, P =0.045)and thrombocytopenia (OR = 0.98,95 %CI 0.96 - 0.99,P = 0.016 )were independent predictive factors of deep remission.Conclusions Infliximab could effectively maintain long term deep remission in treatment of CD.Arthralgia,normalization of hsCRP and PLT counts at 14 th week after induced remission are predictive factor of deep remission.

BACKGROUND:Preliminary studies of our research group mainly focus on the role of nucleus of solitary tract in gastric noxious stimulation and acupuncture point, while dorsal nucleus of vagus nerve, nucleus of solitary tract and area postrema are the necessary component for vagus nerve complex, and dorsal nucleus of vagus nerve plays a crucial role in the regulation of gastric functions. OBJECTIVE:To observe the effect of acupuncture at Zusanli, Neiguan, Pishu and Shenshu acupoints on the gastric-related neurons in dorsal motor nucleus of the vagus nerve. METHODS:The gastric related neurons in dorsal motor nucleus of the vagus nerve of gastric distension rats were identified using extracellular recording technique, according to neuroelectrophysiology method. Acupuncture stimulation was given to Zusanli, Neiguan, Pishu and Shenshu for 15 seconds. The effect of body stimulation on the gastric distension related neurons in dorsal motor nucleus of the vagus nerve of rats was recorded. RESULTS AND CONCLUSION:Among the involved 24 rats, 90 neurons at paraventricular hypothalamic necleus exhibited discharge. Among the discharged neurons, 54 neurons were related to gastric distension. After acupuncture stimulation at Zusanli, Neiguan, Pishu and Shenshu, there were 44, 39, 38, 27 neurons giving a response, the reaction rate was 82%, 72%, 70%and 50%, respectively. Acupunture at different nerve segment acupoints can activate the dorsal motor nucleus of the vagus nerve to different degrees, which is involved in the regulation of gastric motility.

BACKGROUND:Previous studies concerning neuromechanism of acupuncture for regulating gastric function mainly focused on peripheral nerve, involving in central nervous system. In particular, there are few studies addressing higher central nervous system.
OBJECTIVE:To explore the effects of acupuncture at Neiguan (PC6) and Zusanli (ST36) on gastric-related neurons in the hypothalamic paraventricular nucleus.
METHODS:Using microelectrode extracellular recording technique, gastric related neurons in the paraventricular nucleus were found in gastric distension rats. Stimulation was conducted for 30 seconds by hand acupuncture at Neiguan and Zusanli. The effects of acupuncture on gastric-related neurons in the paraventricular nucleus were observed.
RESULTS AND CONCLUSION:The discharge of 109 neurons in the hypothalamic paraventricular nucleus of 60 rats was recorded. A total of 56 gastric-related neurons of the 109 neurons were observed. The number of neurons response to acupunctures at Zusanli, Neiguan, Pishu (BL20) and Weishu (BL21) were respectively 44, 47, 29, and 33, with the reaction proportion of 78.57%, 83.47%, 51.79%and 58.93%. Results suggested that there exist gastric distension stimulation and acupuncture stimulations from neurons soma to visceral reaction in the hypothalamic paraventricular nucleus, which simultaneously participates in the regulation of acupuncture on the gastric function.
