Objective To observe the distribution features of phosphorylated p 44/42 extracellular signal-regulated kinase(p-ERK) induced by affective pain in the anterior cingulate cortex (ACC) of the rat.Methods Twelve male SD rats were randomly divided into the control group (n=6) and spinal nerve ligation (SNL) group (n=6).The rats of the SNL group were exposed to unilateral L5 spinal nerve ligation (SNL) surgery.The behavior was examined by mechanical pain thresholds (MPTs) and the pain affect was measured using open-field test, elevated zero maze.The expressions of p-ERK in ACC (AP 3.2,2.7,2.2mm from Bregma) were detected with immunofluorescence test .Results In comparison with the control group , the unilateral mechanical pain threshold in the SNL group decreased significantly after operation . The operation also resulted in pronounced anxiety-like behavior .The p-ERK labelled cells in different levels of ACC ( AP 3.2,2.7,2.2mm from Bregma) of SNL rats were (11.89 ±2.57),(32 ±4.67 ) and (17.56 ±2.04 ), respectively, while the control group rats were (12.44 ±2.16),(10 ±0.87 ) and (10.11 ±1.36).These data indicated that compared with the control group, the expressions of p-ERK in ACC(AP 2.7,2.2mm from Bregma) increased significantly in the SNL group after operation(P<0.01), besides for the level of ACC(AP 3.2mm from Bregma) (P>0.05).Conclusion The results suggest that the neuropathic pain can result in anxiety-like behavior and increased expressions of p-ERK in ACC of the rat.This change may be closely related to the expressions of p-ERK in ACC(AP 2.7,2.2mm from Bregma), but not to the level of ACC(AP 3.2mm from Bregma).

Objective To explore the relationship between mechanical withdrawal threshold ( MWTs) and local cutaneous blood perfusion ( BP ) in rats with acute inflammation induced by carrageenan.Methods Twenty male Sprague-Dawley ( SD) rats were randomly divided into control and model groups.The acute inflammatory rat model was established by subcutaneously injecting with carrageenan into the left hindpaw.MWTs were measured by Dynamic Plantar Aesthesiometer 37450 before injection ( as base) of carrageenan and at 4 h, 24 h, 48 h, 72 h after carrageenan injection. The local cutaneous BP was detected by Pericam Perfusion Speckle Imager ( Pericam PSI) at the time after measuring of MWTs.The above two behaviors were compared and the relationship between them was analyzed.Results MWTs of the model group rats were decreased while BP significantly increased than that in the control group ( P<0.01 ) .The MWTs and BP in the model rats showed a negative correlation, especially the correlation index showed significant differences at 4 h and 72 h after carrageenan injection ( P<0.01) .Conclusions Carrageenan-induced acute inflammation in rats causes significant changes in mechanical pain threshold, which has a negative correlation with local cutaneous blood perfusion.

Objective:To establish a method for the determination of baicalin in Kang 601 mixture. Methods:An HPLC method was adopted. An Agilent Eclipse Plus-C18 column (250 mm × 4. 6 mm, 5 μm) was used at room temperature (25 ℃) and eluted by methanol-0. 1% phosphoric acid solution(48:52) with a flow rate of 0. 8 ml·min-1 . The detection wavelength was 280 nm and the injection volume was 20 μl. Results:A good linear relationship was obtained between the peak area and the concentration of baicalin within the range of 18. 897-188. 975 μg·ml-1(r=0. 999 9). The average recovery was 99. 86%(RSD=0. 32%, n=9). Conclu-sion:The established method is specific, accurate and reproducible, which can be used for the determination of baicalin in Kang 601 mixture.

Objective To observe the clinical efficacy of electroacupuncture in treating severe functional constipation. Method Seventy patients with severe functional constipation were randomized into a treatment group (35 cases) and a control group (35 cases). The treatment group was intervened by deeply needling bilateral Tianshu (ST25) and Fujie (SP14) with electrical stimulation in addition to ordinary acupuncture at bilateral Shangjuxu (ST37);the control group was by superficially needling the areas beside bilateral Tianshu, Fujie and Shangjuxu with sham electroacupuncture. The two groups were both treated for successive 8 weeks and were followed up for another 3 months. The complete spontaneous bowel movements (CSBMs), Bristol stool form Scale (BSFS) and difficulty in bowel movements were observed every week. Result The two groups both showed significant improvements in average weekly CSBMs (P<0.05,P<0.01), and the CSBMs at the end of the treatment were better in the treatment group than in the control group (P<0.05); the two groups were both effective in improving BSFS and difficulty in bowel movements, without significant between-group differences(P>0.05). Conclusion Electroacupuncture can improve CSBMs in severe functional constipation, but it’s insignificantly different from sham acupuncture in improving stool form and defecation difficulty.

Trigerninal neuralgia is a common refractory disease in clinic. Professor FANG Jianqiao has rich experience through diagnosing and treating the disease for many years. In the first diagnosis, professor FANG underlines the position of damaged neuron and syndrome differentiation. He considers acupuncture should be implemented by stages,namely according to whether the patients are in the period of pain attack, different acupuocture prescriptions are made. Acupuncture manipulation and needle-retention time should be adjusted according to the condition of disease. And the appropriate application of electroacupuncture and transcutaneous electrical acupoint stimulation can strengthen the effect.

BACKGROUND:Indian hedgehog homolog (Ihh) protein and its signal protein Gli1, as wel as Runt related transcription factor 2 (Runx2) are closely related to the pathogenesis of osteoarthritis. The increased expression of these factors is one of the major causes of degenerative joint changes.
OBJECTIVE:To explore the roles of Ihh, Gli1 and Runx2 in the development of osteoarthritis.
METHODS:Thirty Sprague-Dawley rats were randomly divided into two groups:control group (n=10) and model group (n=20). In the model group, rats received unilateral anterior cruciate ligament transection, to establish osteoarthritis model. Ten experimental rats were kil ed at 4 and 12 weeks after surgery respectively. Another 10 rats received unilateral knee arthrotomy as pseudo-operation controls and 10 pseudo-operation rats were kil ed at 12 weeks after surgery.
RESULTS AND CONCLUSION:In the model group, cartilage degeneration was obvious at 4 weeks and became severer at 12 weeks after anterior cruciate ligament transection operation. Expression levels of Ihh, Gli1 and Runx2 in the cartilage were increased significantly at 4 weeks after operation, but decreased at 12 weeks after operation. Experimental findings indicate that Ihh, Gli1 and Runx2 play important roles in the development of osteoarthritis, and their expression levels are significantly increased at early stage of osteoarthritis, which can be regarded as the indicators in the prophylaxis and treatment research of osteoarthritis.
