Objective To observe how the ACC transmits nociceptive information and how it regulates spinal noceciption.Methods A total of 32 male SD rats were randomly divided into four groups:Sham group,CCI group,ACC group,and AP-5 group.After light-dark transition test, forced swimming test (FST),paw withdrawal mechanical threshold (PWMT),paw withdrawal ther-mal latency (PWTL)had been measured,the rats were finally anesthetized,then ACC and the spinal cord was rapidly removed,the expression of cAMP-response element binding protein (pCREB)and extracellular regulated protein kinases (pERK)were measured by Western blot.Results Compared with the sham group,the PWMT of the CCI rats were significantly decreased,rats spent less time in the light compartment and number of transition were decreased (P <0.01 ).The immobility time in FST were also significantly prolonged (P <0.01).After AP-5 injected in bilateral ACC 13 days after CCI operation,the PWMT of the CCI rats were significantly increased,rats spent more time in the light compartment and number of transition were increased (P <0.01).The immobility time in FST were also significantly shortened (P <0.01).Compared with sham group,the expression of pCREB, pERK increased significantly in ACC in CCI group (P <0.01).The expression of pCREB,pERK in spinal cord was increased in CCI group and decreased in AP-5 group (P <0.01 ).Conclusion ACC facilitate the spinal nociception in a descending mode.

Objective:To study the effect of sufentanil combined with dezocine on the PCIA after abdominal operation. Methods:Totally 110 patients undergoing abdominal operation were randomly divided into the experimental group and the control group with 55 cases in each. The two groups were both treated with electronic analgesia pump for the PCIA after the operation. The control group was given dezocine 0. 3 mg·kg-1 ,and the experimental group was given sufentanil injections 0. 1 g·kg-1 plus dezocine 0. 3 mg·kg-1 . The VAS score,adverse drug reactions,Ramesay scores,press number of patient controlled analgesia,exhaust time,recovery time of bowel sounds and bowel audio rate index in the two groups were compared to evaluate the effect of PCIA. Results:All the observed in-dices in the experimental group were significantly better than those in the control group(P<0. 01). The incidence of adverse reactions in the experimental group was significantly higher than that in the control group(P<0. 01). Conclusion:Sufentanil combined with dezocine for the PCIA after abdominal operation shows significantly analgesic and sedative effects,and can notably improve the clinical symptoms,which is worthy of clinical application.

AIM and METHODES: To evaluate the possible signal transduction mechanism of nontargeted mutagenesis in vero cells induced by DNA damaging agent N-methyl-N-nitro-N-nitrosoguanidine(MNNG),the activation of c-Jun NH 2-terminal kinase/stress activated protein kinase(SAPK/JNK) pathway in vero cells induced by MNNG was studied. Western Blot analysis and Solid-phase kinase assay were used to measure the phosphorylation of JNK1 and kinase activity of JNKs, respectively. RESULTS: After 0.2 ?mol/L, 2.5 h MNNG or 1 mg/L, 1 h cycloheximide (CHM) treatment, the proportion of phosphorylated JNK1 in cell extract increased significantly, simultaneously the kinase activity of JNKs increased dramatically(6.7 and 3.0 folds respectively), as measured by the phosphorylation of c-Jun, a substrate of JNKs. CONCLUSION: Both 0.2 ?mol/L 2.5 h MNNG and 1 mg/L 1 h CHM treatment can induce the activation of JNK/SAPK pathway, one of the stress signal transduction pathways, in vero cells.

Objective:To observe the clinical effect of tuina plus foot bath with Chinese medicine for patients with diabetic foot (DF) in early stage.Methods:A total of 70 patients with early-stage DF were randomly allocated by the random number table into two groups,with 35 cases in each group.Patients in the control group received conventional medication,while patients in the observation group received tuina plus foot bath with Chinese medicine on the basis of conventional medication.The clinical efficacy was compared after 2 courses of treatment.Results:After treatment,intra-group comparisons of ankle-brachial index (ABI) showed statistical significance in both groups (both P＜0.05).The curative rate was 83.3％ in the observation group,with the total effective rate of 96.7％,versus 29.4％ and 76.5％ in the control group,respectively,and the between-group comparisons showed statistical significance (both P＜0.05),indicating a better effect in the observation group.Conclusion:Tuina plus foot bath with Chinese medicine has a good therapeutic effect for DF patients in early stage.

OBJECTIVE: To investigate the relationship between pure-tone average (PTA), the fractional anisotropy (FA) of the auditory pathway, cognitive cortex and auditory cortex in presbycusis. METHOD: Twenty-five elderly subjects with presbycusis were participated in the study. PTA, speech discrimination abilities were evaluated in each subject. Diffusion tensor imaging (DTI) was applied to access the FA of the IC, the superior frontal gyrus and the Heschl's gyrus. Compare the difference between two sides of the values of FA in the three areas. Bivariate correlation analysis was performed to evaluate the effects of PTA and FA of the inferior colliculus (IC), the superior frontal gyrus and the Heschl's gyrus on speech discrimination abilities. RESULT: There were no significant differences between the left and right side of the inferior colliculus (P > 0.05). Higher FA values were recorded at the left side of the Heschl's gyrus and the superior frontal gyrus (P < 0.05). Both PTA and the FA of the superior frontal gyrus have a negative association with speech discrimination abilities (P < 0.01, P < 0.05), while the FA of the Heschl's gyrus has a positive association with speech discrimination abilities (P < 0.05). CONCLUSION Our findings indicated that the speech discrimination abilities of the elderly is not only related to the peripheral auditory function, but also to the central auditory and cognitive function.

Objective: To evaluate the eruption of mandible third molar in orthodontic patients with non-extraction or extraction of the lower premolars. Methods: We selected 3 group of the orthodontic patients. One group consisted of 23 subjects (12 males, 11 females, average age 13.5 years) with non-extraction. One group consisted of 23 subjects (12 males, 11 females, average age 13 years) with lower first premolar extraction. One group consisted of 21 subjects (11 males, 10 females, average age 14.07 years) with lower second premolar extraction. The panoramic radiography was taken. The lower third molar angulation and eruption space were measured before and after the orthodontic treatment. The comparison of treatment changes in 3 groups were performed by means of a paired-sample t test using SPSS 17.0 software package. Results: The RS, LS, Rratio and Lratio increased significantly after treatment in patients with lower first premolar extraction(P<0.01). The RM3 and LM3 increased(P<0.05) and RS, LS, Rratio and Lratio increased significantly(P<0.01) after treatment in patients with lower second premolar extraction(P<0.05). Conclusion: The mandibular third molars show improvement in eruption space and inclination in the orthodontic patients with lower premolar extraction.

Objective To analyse the clinical practicability and significance of fertility-sparing surgery for women with recurrent borderline ovarian tumors ( BOT).Methods The clinical and pathological recordings of 12 patients suffered from recurrent BOT in the Obstetrics and Gynecology Hospital of Fudan University from Jan.2002 to Dec.2012 were analyzed retrospectively.The menstruation situation , fertility function , recurrence rate and survival after second conservative surgery were collected and analyzed .Results The average onset age of these 12 patients was 26 years, and none of them had procreation before the second operation.The pathological diagnosis were still BOT and the recurrent sites of 10 patients were still restricted to the ovaries.Of the 12 cases, 8 cases of them had normal menstruation functions and 4 cases had less menstrual volumes or longer menstrual periods.Among 6 cases desired for pregnancy after the second operation,4 cases of them were successful.The spontaneous pregnancy rate was 4/6.The mean duration of follow-up was 53 months(range:23-97 months).All recurrent BOT, three cases developed recurrence once more,two cases of them were just be hinted by B ultrasounds and only one cases was approved to be BOT again by a once more surgical pathology.But no disease related deaths occurred.Conclusions The second fertility-sparing surgery may be feasible for women with recurrent BOT who are young and strongly desired for preservation of fertility.The spontaneous pregnancy rate is satisfactory.However, carefully follow-up is still needed.

Objective To investigate the expression levels and clinical significance of (forkhead box Q1) FOXQ1 and E-cadherin in esophageal squamous cell carcinoma (ESCC). Methods Expression levels of FOXQ1 and E-cadherin were in ESCC tissues (ESCC group, n=42) and adjacent normal esophageal tissues (control group, n=42) were detected using im?munohistochemistry. Correlations of FOXQ1 and E-cadherin expressions with clinical pathological parameters and progno?sis were analyzed between two groups. Results The expression level of FOXQ1 was significantly higher in ESCC group than that in control group(64.29% vs 28.57%,χ2=5.384,P<0.05). The expression level of E-cadherin was significantly lower in ESCC group than that incontrol group(52.38%vs 90.48%,χ2=7.691,P<0.05). There were significant differences in FOXQ1 expressions between different TNM stages and whether lymph node metastasis is involved within ESCC group. There were significant differences in expression of E-cadherin between different tumor differentiation, depth of invasion, TNM stage and whether lymph node metastasis is involved within ESCC group. The expression of FOXQ1 was negatively cor?related with E-cadherin in ESCC (r=-0.412, P<0.05). The 5-year survival rates were significantly lower with high expres?sion of FOXQ1 or with low expression of FOXQ1(18.52%vs 66.67%,χ2=9.737,P<0.05). The 5-year survival rates were significantly higher with high expression of E-cadherinor low expression of E-cadherin(59.09%vs 10.00%,χ2=10.996,P<0.05). A multivariate Cox's proportional hazard regression analysis indicated that high FOXQ1 expression, low E-cadherin expression and lymph node metastasis were independent prognostic factors for ESCC. Conclusion The expression of FOXQ1 and E-cadherin showed a good correlation with ESCC. And examining expressions of both FOXQ1 and E-cadherin in ESCC may have practical values in estimating the prognosis of ESCC and directing future treatment .
