ABSTRACT
<p><b>OBJECTIVE</b>To observe the anesthetic effect and safety of different doses of dexmedetomidine combined with ropivacaine for brachial plexus nerve block in children undergoing polydactyly surgery.</p><p><b>METHODS</b>Eighty children undergoing polydactyly surgery were randomized into 4 groups to receive brachial plexus nerve block with dexmedetomidine at 0.25, 0.50 or 0.75 µg/kg combined with 0.25% ropivacaine (0.20 mL/kg) (D1, D2, and D3 groups, respectively) or with 0.25% ropivacaine (0.20 mL/kg) only (control group). The onset time, duration of brachial plexus nerve block, awakening time, success rate, and incidence of complications were compared among the groups. Results In D2 and D3 groups, the onset time and awakening time were shorter and anesthesia lasted longer than those in the control group. The onset time and awakening time were shorter and anesthesia maintenance time was longer in D3 group than in D1 group. The success rates of brachial plexus nerve block were significantly higher in D1-3 groups than in the control group (P<0.05). Hematoma was found in one of the patients. In each of the 4 groups, laryngeal nerve block occurred in 1 child and respiratory depression in another; 2 or 3 patients had Horner syndrome, and 1 patient in D3 group experienced an episode of lowered heart beat to below 70 min. All the complications were managed properly and the patients all recovered uneventfully.</p><p><b>CONCLUSION</b>Brachial plexus nerve block with 0.5 µg/kg dexmedetomidine combined with 0.25% ropivacaine (0.20 mL/kg) is safe for effective anesthesia in children undergoing surgery for polydactyly.</p>
ABSTRACT
<p><b>OBJECTIVE</b>To compare clinical efficacy of double titanium plate and clavicular hook plate for the treatment of Neer II distal clavicular fracture.</p><p><b>METHODS</b>From April 2013 to June 2015, 42 patients with Neer II distal clavicle fractures were non-randomly selected, including 25 males and 17 females. All patients were fresh closed fractures. Twenty patients were treated with double titanium plate with tight rope(group A), including 11 males and 9 females aged from 16 to 49 years old with an average age of(33.8±10.7) years;the time from injury to operation ranged from 2 to 5 days with an average of (3.5±1.8) days. Twenty-two patients were treated with clavicle hook plate(group B), including 14 males and 8 females aged from 27 to 53 years old with an average age of (37.7±9.9) years;the time from injury to operation ranged from 2 to 5 days with an average of (3.1±2.0) days. Operative time, blood loss, hospital stays and postoperative complications were observed and compared; fracture healing were compared among preoperative, postoperative at 1, 3 and 6 months; VAS and ASES scoring were used to evaluate shoulder function.</p><p><b>RESULTS</b>All patients were followed up from 6 to 12 months with an average of 7.2 months. All incisions were healed at stage I. Blood loss in group A were less than that of group B(<0.05); while there were no significant difference in hospital stays and operative time between two groups. No shoulder pain occurred in group A, 4 cases occurred shoulder pain in group B, and had significant difference. Fracture healing time ranged from 3 to 6 months with an average of 4.3 months. VAS score and ASES score in group A were higher than that of group B in pain, function and total score.</p><p><b>CONCLUSIONS</b>Compared with clavicle hook plate, double titanium plate has advantages of shorter incision wound, less bleeding and simply operation, less complications, and could avoid pain for removing internal fixation. Over reduction of acromioclavicular joint during operation does not affect its superior curative effect. It is better choice for the treatment of Neer II distal clavicle fracture.</p>
ABSTRACT
<p><b>OBJECTIVE</b>To explore the efficacy and safety of Qiangyue Cream (QYC) for treatment of chronic simple lichen (CSL).</p><p><b>METHODS</b>A randomized, double-blinded, parallel controlled clinical trial was performed in 80 patients with CSL allocated in two groups, the 40 locally treated with QYC as the tested group, and the 40 treated with halometasone cream as the control group, with the treatment lasted for 2 successive weeks.</p><p><b>RESULTS</b>A better effect in improving the scores of clinical symptoms, degree of itching and lichenoid change was shown in the tested group than that in the control group (P < 0.05), but insignificant difference was found between the two groups in the cure rate and the total effective rate. The occurrence of adverse reaction in both groups was in 1 case.</p><p><b>CONCLUSION</b>QYC is a safe and effective external drug for CSL treatment, its efficacy might approach that of halometasone cream, with a better effect for relieving itching and milder adverse reactions.</p>

Objective To explore and summarize the heart-shape anastomosis for hirschsprung′s disease .Methods Before the operation,the colon was cleaned thoroughly ,31 cases of this group (8 month-6 years old)underwent colonic pull-through and the dilated segment of colon was pulled out and resected.Normal colon and lower segment of rectum′s stomosis were stomosed as heart-shape (higher anterior and lower posterior).After replacing the colon and stomosis ,close the abdomen layer by layer.Results All 31 cases anus sphincter muscle were retained at most degree,so that retained their function of normal defecation .All 31 cases were healed and discharged, without one case with early complications as stomosis fistila,et al.No stomosis stenosis or other late period complication were found in 24 cases with long period follow-up.Conclusions Heart-shape stomosis is a good method for hirschsprung′s disease,especially fitful to the common type and short-segment type and long-segment type with diseased part in sigmoid colon .This method is easy,convenient,no special equipment was needed,easy to be publicized.
