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.

OBJECTIVETo explore the genotypes of human papilloma virus (HPV) in male patients with condyloma acuminate in Lishui area of Zhejiang Province, China.

METHODSUsing HybriMax, we identified the genotypes of HPV of the verruca samples from 110 male condyloma acuminate patients aged 16 - 65 years in Lishui area.

RESULTSHPV infection was detected in 107 (97.27%) of the condyloma acuminate patients, including 76 cases (71.02%) of simple infection and 31 cases (28.97%) of multiple infection. The peak age of infection was 21 - 40 years old. Totally, 14 genotypes of HPV were identified, including the high-risk genotypes as HPV16, 53, 52, 33, CP8304, 58, 51, 45, 66, 68, and 59, which accounted for 44.85% of the cases, and the low-risk ones as HPV6, 11, and 19 (43), with an infection rate of 93.45%.

CONCLUSIONThe low-risk genotype is a dominant type of HPV infection and the rates of high-risk genotype and multiple infection are high among the male condyloma acuminate patients in Lishui area.

To discuss the feasibility of the pharmacodynamic evaluation method for traditional Chinese medicine (TCM) formula particles, with traditional decoction for reference and the intervention of Magnoliae Officinalis Cortex in rats with ulcerative colitis (UC). First of all, the similarity of traditional Magnoliae Officinalis Cortex decoction and formula particles of different manufacturers was defined by using the IR fingerprint. The UC rat model was established and given Houpo formula particles of different doses and manufacturers, with the decoction for reference, in order to observe disease activity index (DAI), colon mucosa damage index (CMDI), pathologic changes, nitric oxide (NO), endothdin (ET), substance P, vasoactive intestinal peptide (VIP). Their intervention effects on UC rats were compared to study the difference between Sanjiu and Tianjiang Houpo formula particles, in order to demonstrate the feasibility of the pharmacodynamic evaluation method for Houpo formula particles. According to the results, Houpo formula particles showed similar pharmacodynamic actions with the traditional decoction. The pharmacodynamic comparison of Houpo formula particles of different manufacturers showed no statistical significance. The experiment showed that on the basis of the TCM compounds, a prescription dismantlement study was conducted to define target points of various drugs. The traditional decoction was selected for reference in the comparison of corresponding formula particles for their pharmacodynamic equivalence. This method could avoid controversies about single or combined boiling of formula particles, and give objective comments on the pharmacodynamic effect of the formula particles. The method is proved to be feasible.

Objective To observe the clinical efficacy of acupuncture plus auricular point sticking in improving tobacco withdrawal symptoms after smoke cessation. Method Forty-eight patients with tobacco withdrawal symptoms were randomized into a treatment group and a control group, 24 in each group. The treatment group was intervened by acupuncture plus auricular point sticking, while the control group was by auricular point sticking. The daily consumption of tobacco, Fagerstrom Test of Nicotine Dependence (FTND), and Self-rating Scale of Tobacco Dependence (SSTD) were observed before and after intervention, and the smoke cessation rate was also compared. Result The smoke cessation rate was 83.3%in the treatment group versus 54.2%in the control group, and the difference was statistically significant (P<0.05). After intervention, the daily consumption of tobacco and SSTD score in the treatment group were significantly changed and markedly different from that in the control group (P<0.05). The FTND scores were significantly changed after intervention in both groups (P<0.05). There was a significant difference in comparing the FTND score between the two groups after intervention (P<0.05). Conclusion Acupuncture plus auricular point sticking can improve the tobacco withdrawal symptoms.

Objective: To discuss the influence of comprehensive nursing intervention on patient’s oral mucositis with hematopoietic stem cell transplantation. Methods:One hundred and seventy four examples of patients with hematopoietic stem cell transplantation were equally and randomly divided into two groups, which are intervention group and control group. The usual care was given to the control group, while both the usual care and comprehensive nursing intervention were given to the intervention group. The comparative study of the occurrence and severity degree of oral mucositis in these two groups after one week pretreatment was conducted. Results:The occurrence rate of oral mucositis in intervention group and control group was 54.47%and 68.97%respectively. And there is no obvious significance of the occurrence rate before and after the intervention(x2=2.47, P>0.05). Nevertheless, the comprehensive nursing intervention could significantly lessen the severity of oral mucositis, and help to control the inflammation and promote healing. Conclusion:comprehensive nursing intervention could effectively reduce the occurrence degree of oral mucositis in the patients with hematopoietic stem cell transplantation.
