ObjectiveTo study the distribution and expression of NMDA receptor subunit 2A in the spinal cord of morphine tolerant rats. MethodsTwelve Sprague-Dawley rats were randomly divided into two groups with 6 rats each: control group (C) were intrathecally administrated 0.9% NaCl 10μl and morphine group(M) received 10μg morphine (i.t.). Drugs were administrated twice daily for 7 consecutive days. Tail flick latency (TFL) in the hot water immersion test was used to evaluate changes of thermal hyperalgesia latency of each group before and 30min after administration every morning. Rats were killed the day after last administration and L4～5 segment of the spinal cord was removed for determination the expression of NR2A by immunofluorescence method. ResultsTFL of group M was decreased gradually after chronic administration of morphine intrathecally. There was no significant difference between group M[(3.25±0.93)s] and group C[(2.66±0.27)s] on the 7th day (P＞0.05). A morphine tolerant model was established successfully. NR2A was distributed throughout the rat spinal cord. The expression of NR2A in group M(OD:9617±1233) was increased compared with group C(OD:2.66±0.93) (t=3.133,P＜0.05).ConclusionThe expression of NR2A was upregulated after repeated administration of morphine intrathecally in the superficial dorsal horn of spinal cord of morphine tolerant rats,which may be part of the mechanisms of morphine tolerance.

Tendons are dense connective tissues that mediate the attachment of the muscle system to the skeletal system. While the methods for clinical tendon repair remain less satisfactory, tissue engineering may pro- vide promising future. Therefore, understanding the natural tendon development process is important for tendon en- gineering. Scleraxis and Tenomodulin are relatively specific molecule makers for tendon and ligment and play im- portant roles in the tendon development. This article gives review of the molecular structure, the expression regula- tion, and the roles of Scleraxis and Tenomodulin in tendon development, in order to better understand the process of tendon development.

0.05) in tail flick test.MPE% in group MK was always higher than group M and descended more slowly than group M,especially from the d4 to d8(P0.05). Conclusion Ketamine could block the development of morphine tolerance partly due to its inhibition effect on pCREB protein.

Objective:To assess the efficacy and safety of oncoplastic breast-conserving surgery (OBCS) in the treatment of early breast cancer. Methods:The clinicopathological data of breast cancer patients who were treated with OBCS (67 cases) and standard breast-conserving surgery (SBCS;117 cases) in Affiliated Cancer Hospital of Guangxi Medical University were retrospectively analyzed. Postop-erative complication, specimen weight, margins, and surgery re-excision rate between the two groups were compared. Results:Sero-ma (14.9%versus 48.7%, P<0.001), hematoma (4.5%versus 14.5%, P=0.035), and poor wound healing (3.0%versus 11.9%, P=0.036) were more common in the SBCS group than in the OBCS group. The patient satisfaction in the OBCS group was statistically higher than in the SBCS group (P<0.05). Compared with standard surgery, oncoplastic techniques can be employed for significantly larger tumors (25.04 mm versus 21.14 mm, P<0.001). OBCS resulted in higher mean specimen weights (92.24 g versus 57.44 g, P<0.001), wider clear nearest margins (12.04 mm versus 9.58 mm, P<0.001), and wider furthest margins (24.16 mm versus 15.24 mm, P<0.001). No statisti-cal increase was observed in further surgery re-excision of margins. Conclusion:OBCS is more successful than standard wide local exci-sion in treating larger tumors and obtaining wider radial margins. Oncoplastic approach showed no increase in postoperative complica-tion rate. The postoperative complication was excellent. OBCS is a safe and effective procedure for early breast cancer.

OBJECTIVE:To investigate the perioperative prophylactic use of antibacteirals in patients undergoing simple goiter surgery.METHODS:The perioperative prophylactic use of antibacteirals in 240 patients of our hospital undergoing simple goiter surgery was analyzed statistically in respect of drug variety,DDDs,drug combination,medication time,curative effects,adverse drug reactions(ADR)etc.RESULTS:Of the 240 cases,238(99%)received prophylactic antimicrobials,with cephalosporins and quinolones dominating the list in terms of DDDs.The irrational drug use manifested as high proportion of high grade drugs in preventive medication,the prolonged postoperative use of antibacterials,and high rate of combined use of drugs etc.CONCLUSION:It is urgent to intensify physicians' consciousness about rational perioperative use of antibacterials.

Objective: We investigated experimentally the changes of intestinal immunity following shock and resuscitation after trauma. Method:The experimental model was made in rats, which underwent laparotomy, then bleeding and reinfusing through the right fetmoral artery. Result: The concentration of IgA following shock and resuscitation were significantly higher than that before shock.. The concentration of IgA 24 h following resuscitation was the lowest, and was significantly lower than that at the end of shock.. The endotoxin in portal vein following shock and resuscitation were higher than that before shock.. The endotoxin level 24 h following resuscitation was the highest, and markedly higher than that at the end of shock. Conclusion: The traumatic shock and resuscitation are capable of causing intestinal immunosuppression and endotoxemia.

Objective To investigate the effects of kui-yang-fang on trefoil factor 1 ( TFF1 ) , epidermal growth fac-tor ( EGF) and epidermal growth factor receptor( EGFR) in acetic acid induced gastric ulcers of rats. Methods50 rats were randomly divided into five groups. The rats of the gastric ulcer model were used by the icy acetic acid. After drug treatment for 14 days,the rats gastric mucosa was collected to compare to the ulcer index,then check the content of TFF1,EGF and EGFR with RT-PCR,and observe TFF1,EGFR with immunohistochemical staining. Re-sults Compared to the control,the levels of TFF1 and EGF in model group decreased, and the difference was not statistically significant. The EGFR level of model group was higher than that of normal group with no statistically significant difference. But the increase of kui-yang-fang groups and ranitidine group was more obvious,the difference was statistically significant (P<0.01). Compared to the model group,kui-yang-fang and ranitidine groups signifi-cantly elevated the level of TFF1,EGF and EFR in gastric ulcer,the difference was statistically significant ( P<0.01 ) . Immunohistochemical staining showed that TFF1 and EGFR expression in kui-yang-fang and ranitidine groups were significantly increased,the difference was statistically significant (P<0.01), but the increase of kui-yang-fang of high-dose group was more obvious. Conclusion One of the possible mechanism is kui-yang-fang pro-motes expression of TFF1,EGF and EGFR to protect and repair gastric tissue.
