Objective To study the effect of dexmedetomidine(DEX)intrathecal administration on formation of chronic neuropathic pain induced by chronic constriction injury(CCI)in rats. Methods One hundred and twenty healthy adult male Sprague-Dawley(SD)rats were divided randomly into four groups(each n=30):sham group, model group,30μg/kg and 60μg/kg DEX intrathecal injection group(D30 group,D60 group). The CCI model was installed by left sciatic nerve ligaturing,sham surgery was done by exposing the sciatic nerve without ligation,and 30 μg/kg,60 μg/kg DEX(each,10 μl)and 10 μl normal saline were given intrathecally in D30,D60 and model groups respectively,all kinds of injection being once a day for 7 days. Hind paw mechanical contraction reflex threshold(MWT),heat-shrinkable reflex latency(TWL)and the score of motor dysfunction of hind extremity in rats were recorded on 1 day before ligation and 1,3,7 days after operation,and before ligation and 1,7,14 and 21 days after operation,the contents of tumor necrosis factor-α(TNF-α),interleukin(IL-1βand IL-6)in intumescentia lumbalis were measured by enzyme linked immunosorbent assay (ELISA). Results Compared with before operation,there were no significant differences in values of MWT,TWL,the motor function evaluation,TNF-α, IL-1β,and IL-6 at each time points(all P>0.05);however,with the prolongation of time,MWT and TWL were decreased,and the motor function evaluation,TNF-α,IL-1β,and IL-6 were increased in all the other groups. Compared with those of the sham group,MWT and TWL were declined,and the motor function evaluation,TNF-α, IL-1β,and IL-6 were elevated in model group. Compared with those of model group,30μg/kg and 60μg/kg DEX could significantly raise MWT(g)and TWL(s),obviously improve motor function and remarkably decrease the contents of TNF-α(pg/mg),IL-1β(pg/mg)and IL-6(pg/mg)in the spinal cord of CCI rats from 1 day after operation. And the changes in 60 μg/kg DEX group were more significant than those in 30 μg/kg DEX intrathecal injection group〔postoperative 1 day MWT:39.3±1.3 vs. 20.3±2.2,TWL:10.9±0.4 vs. 8.2±1.1,motor function score:2.00±0.00 vs. 2.00±0.75,TNF-α:33±7 vs. 125±18,IL-1β:108±12 vs. 203±34,IL-6:156±39 vs. 405±75,all P<0.05〕. Conclusions The DEX intrathecal administration has certain degree of dose-dependent therapeutic effect on hyperalgesia in CCI rat models. The mechanism is related to the amelioration of inflammatory reaction at the lumbar segment of spinal cord.

Objective The aim of this study is to evaluate whether video -assisted thoracoscopic surgi-cal( VATS) lobectomy is as effective as open thoracotomy lobectomy for complete dissection of the mediastinal lymph node(MLN).Methods Patients with clinical stage N0 lung cancer who underwent lobectomy between January 2008 and June 2013were retrospectively evaluated based on the LN station resected and lobectomy proce -dure used,and a resection ratio was calculated .Nodal stage and the proportion of patients ,from whom at least three MLNs and station 7were dissected and compared by lobectomy type .Results Of the 201 patients enrolled in the study,84 and 117 underwent VATS and open thoracotomy lobectomies ,respectively.The mean number of LNs dissected at station 3a was similar in the two groups (1.34 ±2.58 vs.1.52 ±1.78;P>0.05),but the re-section ratio differed(39%sv .63%;P <0.05).However,there were no differences at stations7 and 9R in terms of the number of LNs dissected or resection ratio for the right -sided approaches (P >0.05).There were no differences in the number of LNs dissected or resection ratio between the two groups for stations 4 L,5 L6, L,7 L, and9 L for the left-sided approaches .Only station 8L showed significant differences between the VATS and open thoracotomy groups in the number of LNs dissected (0.12 ±0.44 vs.0.46 ±0.71;P<0.05)and resection ratio (8%vs.36%;P<0.05).There were no differences in the number of LNs dissected or resection ratio between groups for station 7:82.1%of patients in each group had at least three MLNs and station 7 removed(P>0.05). The Kaplan-Meier 5-year survival was also similar between the two groups (log-rank test,P>0.05).Con-clusion VATS lobectomy is as effective as open thoracotomy lobectomy for the dissection of MLNs .Thus,VATS lobotomy resection will continue to be offered as the best choice for patients with clinical stage N0.

Objective:In order to prevent tracheostomal stenosis (TSS) instead of laryngectomy cannulas after total laryngectomy, Nickel\|Titanium shape memory alloys(NI\|SMA) stents in tracheostome were produced and applicated in clinic. Methods: The diameter of NI-SMA is 0.8mm, and Ni 50%, Ti 50%. The shape of the Ni\|SMA stent is the two\|threeth of circumference and its diameters are 18mm, 19.5mm, 21mm. The stents were implanted between the first and the second tracheal cartilage ring of the stump in twenty\|two patients with advanced laryngeal carcinoma or hypopharyngeal carcinoma or esophagul carcinoma in neck. All the patients were free of laryngectomy cannulas after operation. Results: Nieteen patients healed at one stage. Infections after operation were seen in three cases. Eight patients received radiotherapy after total laryngectomy. The NT\|SMA stent did not influence radiotherapy after operation. The TSS occured in six of the patients. A simple procedure named “doughnut” for widening stenosis was performed successfully with an electric cautery knife in all the patients with tracheostomal stenosis after operation. Conclusions: The results suggested that the NT\|SMA stents can prevent from traheostenosis instead of metal laryngectomy cannulas after total laryngectomy.

BACKGROUND: Ankle fracture combined with deltoid ligament rupture and distal tibiofibular syndesmosis injury occurs occasionally. Its treatment with distal tibiofibular syndesmosis screw fixation or deltoid ligament repair remains controversial. The former appears with poor reduction, broken nails, secondary surgery and other problems.OBJECTIVE: To observe the clinical effectiveness of suture anchor repair for ankle fracture combined with deltoid ligament injury.METHODS: Twelve patients with ankle fracture combined with deltoid ligament injury were selected from the First Affiliated Hospital of Guangzhou University of Chinese Medicine between January 2013 and December 2015. All patients were treated with open reduction, internal fixation, and anchor repair, but without distal tibiofibular syndesmosis screw fixation. The curative efficacy and joint stability were observed.RESULTS AND CONCLUSION: (1) All patients were followed-up for more than 12 months. (2) The modified Baird-Jackson scoring system showed excellent in nine cases, good in two cases, average in one case, poor in none case, and the excellent and good rate was 92%. (3) At 1 year after internal fixation, the X-ray examination showed the malleolus gap and talus slope angle of the affect side were (3.47±0.12) mm and (0.45±0.18)°, and the malleolus gap and talus slope angle of the healthy side were (3.44±0.05) mm and (0.43±0.14)°, and there was no significant difference between two sides (P > 0.05). (4) These results indicate that the suture anchor can repair the anatomy and biomechanics of deltoid ligament with stable ankle joint, and secondary surgery is unnecessary.
