Objeetlve To evaluate the role of IL-1β and TNF-α in the spinal cord in a murine model of bone cancer pain(BCP)induced by activation of glial cells.Methods Three hundred and sixty male 8-10 weeks old C3H/He mice weighing 18-22 g were randomly divided into 6 groups(n=60 each):group I nomal control (group N);group Ⅱ sham operation (group S);group Ⅲ BCP+aCSF(group aCSF);group Ⅳ BCP+FC (group FC);group V BCP+MI(group MI) and group Ⅵ BCP+FC+MI (group FC-MI).BCP was produced by inieeting fibrosarcoma cells of bone into the medullary cavity of left ealcaneus bone.Intrathecal catheter was placed in the 4 BCP groups(group Ⅲ-Ⅳ).FC 0.5 nmol/5 μl or/and MI 16 μg/5 μl were injected IT once a day for 21 consecutive days after operation.The mechanical threshold to von Frey filaments was measured at 0.5 h(T0)before injection of fibrosarcoma cells and at 3,5,7,10,14,21 d(T1-6)after injection of fibrosarcoma cells.Twelve animals of each group were killed and L4.5 segment of the spinal cord was removed at T0,1,3,5,6 for determination of IL-1β and TNF-α content (by ELISA) and expression (by immuno-flurorescence) in the spinal cord. Results The mechanical threshold was significantly decreased at T1-6, while IL-1β content at T1,3,5,6 and TNF-α content at T5,6 was significantly increased in group BCP, FC, MI and FC + MI compared with those at T0 and group C (P < 0.05). Compared with group BCP, the mechanical threshold was significantly increased at T1-6 in group MI and FC + MI and at T4-6 in group FC, IL-1β content was significantly decreased at Ts,3,5,6 in group MI and FC + MI and at T5,6 in group FC and TNF-α content was significantly decreased at T5,6 in group FC, MI and FC + MI ( P < 0.05). Conclusion IL-1β and TNF-α in the spinal cord is involved in the process of glial cell activation-induced BCP.

Objective To observe characteristics of the activity in resting brain of asymptomatic reflux esophagitis (RE) patients,and explore the role of default network in the pathogenesis of asymptomatic RE.Methods Functional magnetic resonance imaging (fMRI) was performed to scan the brains of 15 asymptomatic RE patients,15 symptomatic RE patients and 15 healthy volunteers under no-mission-stimulation state.With fractional amplitude of low frequency fluctuation (fALFF),characteristics of the strengthened and weakened regions of asymptomatic RE patients,symptomatic RE patients and healthy individuals were compared and analyzed.SPM 5 was applied for data preprocessing.Single-sample t test was performed to observe the noticeable active regions of each group under resting state,and then double-sample t test was used to compare the characteristics of active regions of the entire brain between asymptomatic RE patients and symptomatic RE patients or healthy individuals.Results Under resting state,the active brain regions of asymptomatic RE patients,symptomatic RE patients and healthy individuals were similar.The activity of only small part of brain regions in visceral sensory processing relevant networks changed.There was no significant difference in the active regions of default network under resting state between asymptomatic RE patients and healthy individuals.Compared with symptomatic RE patients,fALEF decreased at right central sulcus cover,right superior temporal gyrus,right insula,right transverse temporal gyrus,right postcentral gyrus,superior temporal gyrus and temporal pole (X=50,Y=-6,Z=12,t=2.7874,P＜0.01).Conclusion The difference in characteristics of activity in default network under resting state may play an important role in the pathogenesis of asymptomatic RE.

Aim To investigate the effect of intrathecal injection(it) of minocycline(MC),a selective microglia inhibitor,on the maintenance of pain in a murine model of cancer pain.Methods Forty-two male C3H/He mice were randomly divided into 3 groups(n=14 each):sham+PBS group was operated and received 10 ?l PBS injection into calcaneus medullary space;sarcoma+PBS group and sarcoma+MC group were operated and received 2?105 sarcoma cells/10 ?l PBS implantation into calcaneus medullary space.On the PID11(post-implantation day 11),10 mice were taken from each group randomly,sarcoma+PBS group and sham+PBS group were received 0.9% NS(5 ?l) it sarcoma+MC group was received MC(1 nmol,5 ?l) it Mechanical pain threshold and cold hyperalgesia assay were measured before and after it at 0.5,1,2,4,8,24 h.The last 4 mice of each group were received a normally non-noxious palpation of the ipsilateral heel 90 min on the PID12 after it,then the animals were killed and L4-6 segment of spinal cord was removed for analysing the c-fos expression(by immunohistochemistry).Results Bone cancer pain decreased the mechanical and cold pain threshold and activated the c-fos expression in the spinal cord;MC it transient attenuated bone cancer pain-induced hyperalgesia and allodynia and suppressed the expression of c-fos protein.Conclusion The activation of microglia in the spinal cord may be involved in the maintenance of bone cancer pian.

BACKGROUND: Percutaneous vertebroplasty (PVP) is usually used for osteoporotic thoracolumbar fractures,which has various advantages such as easy to operate, short operation time, less trauma, rapid recovery,analgesic effect and so on. But its application is restricted due to nerve compression symptoms and pulmonary embolism caused by bone cement leakage. Thereafter, how to reduce the leakage of bone cement is an issue of concern.OBJECTIVE: To investigate the relationship between the lumbar quantitative computed tomography (QCT) values and contrast agent dispersion in osteoporotic thoracolumbar fractures. METHODS: Sixty cases of osteoporotic thoracolumbar fractures undergoing PVP were enrolled, and received QCT examination before surgery, and contrast agent was injected intraoperatively. X-ray examination was conducted to detect the bone mineral density, contrast agent dispersion and leakage of bone cement, and the relationship between the lumbar QCT values and contrast agent dispersion as well as leakage of bone cement.RESULTS AND CONCLUSION: (1) There were 110 vertebral fractures, and 74 vertebrae with contrast agent diffusing more than vertebral midline, accounting for 67.3%. There was significant difference in the contrast agent dispersion among groups (P < 0.05). (2) The bone cement leakage showed no significant difference among groups after injected with bone cement by unilateral or bilateral approach (P > 0.05). (3) These results suggest that contrast agent dispersion in osteoporotic thoracolumbar fractures has a certain relationship with the lumbar QCT values, and lumbar QCT values with more contrast agent dispersion, but the lumbar QCT values have no correlation with bone cement leakage. Therefore, choosing a appropriate approach based on the QCT values and contrast agent dispersion can reduce leakage and improve the safety of PVP.

Ureteral calculi after lingual mucosal ureteral reconstruction are rare. In this paper, we reported a case of a male patient who had undergone robotic-assisted laparoscopic lingual mucosal right ureteroplasty. Calculi were found in the right reconstructed ureteral segment 4 months after surgery. Then the patient underwent transurethral ureteroscopic holmium laser lithotripsy combined with a stone retrieval basket, and postoperative urological CT showed no residual calculi in the right ureter. No recurrence of right ureteral calculi or complications were observed during 20 months of follow-up.

Objective:To construct a C57BL/6 mouse model of simulating transurethral thulium laser vaporization prostatectomy.Methods:Twelve male C57BL/6 mice were selected to undergo transvesical vaporization resection of the urothelium covering the urethra of the prostate using thulium laser. The urethral tissue of the prostate was retrieved on the 1st, 3rd, 5th, and 7th days after the surgery. HE staining was used to observe the process of re-epithelialization of the urethral wound of the prostate. Immunohistochemical (IHC) staining was used to detect whether the re-epithelialized cells of the urethral wound of the prostate expressed urothelin Ⅲ (UPⅢ).Results:On the first day after surgery, HE staining showed complete destruction to the urothelium covering the urethra of the prostate, with a large amount of coagulative necrotic tissue on the wound surface, and IHC staining showed no expression of UPⅢ on the wound surface. On the 3rd day after surgery, HE staining showed that there were still no regenerated epithelial cells on the wound surface, with coagulation necrosis tissue significantly reduced, and the urethral cavity was clearly visible. And IHC staining showed no expression of UPⅢ on the wound surface. On the 5th day after surgery, HE staining showed 1-2 layers of regenerated epithelial cells lacking cell polarity on the wound surface, and IHC staining showed that the regenerated epithelial cells expressed UPⅢ. On the 7th day after surgery, HE staining showed 4-6 layers of polar regenerated epithelial cells on the wound surface, and IHC staining showed the multiple layers of regenerated epithelial cells expressing UPⅢ.Conclusions:Based on the simulation of transurethral thulium laser vaporization resection of the prostate, the thulium laser and ultra micro endoscope system were used to vaporize the urothelium covering the urethra of the prostate, and the process of urethral re-epithelialization of the prostate can be observed after surgery. The establishment of the C57BL/6 mouse model simulating thulium laser vaporization prostatectomy provides a new research platform for studying the mechanism of wound repair after prostatectomy.
