OBJECTIVETo investigate the reconstruction of thumb II-III degree defect by big toe wrap-around flap combined with second toe proximal interphalangeal joint.

METHODSBetween May 2004 to July 2012, 25 cases with thumbs II-III degree defects were treated. The ipsilateral big toe wrap-around flap combined with second toe proximal interphalangeal joint was designed to reconstruct the thumb defects based on the thumb size on the healthy side. The distal end of hallux was covered by flap at tibial side. The wound at the fibula side was covered by skin graft and flap. The bone defect at the second toe was filled with remnant hallux or iliac bone.

RESULTSAll the 25 reconstructed thumbs survived completely. The patients were followed up for 6-26 months without any joint degeneration. According to the finger reconstruction functional criterion publicized by China Medical Association, the finger function was assessed as excellent in 10 case, good in 11 cases, poor in 4 cases. Joint necrosis happened in 2 cases and bone malunion in 2 cases. The 4 cases received dead bone debridement and iliac bone graft. No malfunction occurred in the donor site.

CONCLUSIONSOur surgical method is a currently effective way to reconstruct II-III degree thumb defects. Satisfactory functional and cosmetic results can be achieved both in donor site and recipient site.

Objective To explore the effect of Ulinastatin on proinflammatory cytokines of patients undergoing operation of intracranial aneurysm embolization. Methods 40 patients undergoing operation of intracranial aneurysm embolization were randomly divided into 2 groups (n = 20): ulinastatin group (Group U), normal saline group (Group C). In group U, 6 000 IU/kg Ulinastatin was infused via vein before anesthesia induction, the group C received the injection of isovolume normal saline. Exsanguinated arterial blood at T1, T2, T3, T4 and T5 five time points were taken to measure TNF-α and IL-6 in serum. Results The contents of TNF-α and IL-6 in serum both increased at T3, T4 and T5 compared to that at T1 in both groups; both TNF-α and IL-6 significantly decreased in Group U compared to that in Group C at the same time point. Conclusion Ulinastatin may inhibit the release of inflammatory mediators and lighten cerebral ischemia-reperfusion injury in patients undergoing operation of intracranial aneurysm embolization.

[Summary] Thyroid nodules are the most common endocrine and metabolic diseases,and most of them are accidental nodules.How to distinguish the state between benign and malignant thyroid nodules is the clinical core problems in diagnosis and treatment.In addition to detailed history collecting and physical examination,highresolution ultrasound,serum thyrotrophin levels,and fine needle aspiration biopsy (FNAB) form the basis for the diagnosis of thyroid nodules.Endocrinologists should grasp the indications of FNAB.When the pathological finding is unable to distinguish between benign and malignant nodules,molecular or genetic diagnosis should be adopted for further diagnosis.Appropriate treatment is selected according to the definitive results.In this article,we share the whole process that one case with thyroid nodule was diagnosed as papillary thyroid carcinoma and eventually treated with surgery,so as to make clinicians pay more attention to thyroid nodules with standardized clinical diagnosis and treatment.

Objective To compare the efficacy of ultrasound-guided continuous fascia iliac compartment block (cFICB) and neurostimulator-guided continuous femoral nerve block (cFNB) for postoperative analgesia in patients undergoing total knee arthroplasty.Methods Sixty-six ASA Ⅰ or Ⅱ patients,aged 46-78 yr,weighing 45-88 kg,scheduled for unilateral total knee arthroplasty,were randomly divided into 2 groups (n =33 each):cFNB group (group Ⅰ) and cFICB group (group Ⅱ).At 30 min before surgery,the patients received FNB guided by neurostimulator in group Ⅰ and FICB guided by ultrasound in group Ⅱ.A bolus of 0.5％ ropivacaine 20 ml was injected and a catheter for continuous nerve block was inserted in both groups.At 0.5 h after surgery,the catheter was connected to a patient-controlled analgesia (PCA) pump.PCA with 0.2％ ropivaeaine was used for postoperative analgesia (48 h).The PCA pump was set up to deliver a 5 ml bolus dose with a 30-min lockout interval and background infusion at 5 ml/h.VAS score was maintained ≤ 3.The distribution of sensory block was assessed at 10 min after the first administration,and at 0.5,4 and 24 h after surgery.The effective rate of sensory block was calculated.When VAS score ＞ 4,tramadol 50 mg was given intravenously or orally every 12 h as a rescue analgesic.When VAS score ＞ 5,pethidine 50 mg was injected intramuscularly as a rescue analgesic.The number of attempts was recorded during 0-4 h,4-12 h and 12-24 h after surgery.The consumption of tramadol and pethidine was also recorded during 0-24 h and 24-48 h after surgery.The sleep quality score during the nighttime was also recorded during 0-24 h and 24-48 h after surgery.Vascular puncture and parasthesia during nerve block were recorded.The toxic reaction,severe nausea and vomiting (lasting for more than 1 day) and nerve damage were recorded after surgery.Results Compared with group Ⅰ,the effective rate of sensory block in the medial aspect of the thigh was significantly decreased at 10 min after the first administration,and the effective rate of sensory block in the lateral aspect of the thigh was significantly increased at 0.5 h after surgery in group Ⅱ (P ＜0.05).There was no significant difference in the number of attempts,consumption of tramadol and pethidine,and sleep quality score during the nighttime during different time periods between the two groups (P ＞ 0.05).No vascular puncture or parasthesia was found during nerve block in the two groups.No toxic reaction,severe nausea and vomiting or nerve damage was found after surge,y in the two groups.Conclusion Ultrasound-guided cFICB has the similar analgesic efficacy with neurostimulator-guided cFNB after operation,but it can provide a wider distribution of sensory blockade in patients undergoing total knee arthroplasty.

Objective To investigate the effect of rocuronium of on the function of acetylcholine receptor (AchR)/channel in cone neurons of hippocampal cortex in rats.Methods SD rats of both sexes (2-5 days old) were killed by decapitation. Brain was immediately removed and hippocampal cortex was cut into slices which were incubated in decalcified and magnesium-free artificial cerebro-spinal fluid (CSF) and mechanically dissociated and then digested in artificial CFS containing 2.5% trypsin. Cell suspension was prepared. The AchR/channel function was studied in the absence and presence of various concentrations of rocuronium (0, 0.05, 0.1, 0.2, 0.4mmol? L-1) and/or atropine 0.1 mmol ?L-1 using patch clamp technique.Results (1) The conductance, open probability (P0) and short term open constant (?01) were significantly higher in R-0.05 group than those in the control group (R-0) , but there was no significant difference in long term open constant (?02) , short term close constant( (?c1) and long term close constant(?c2) between the two groups. The conductance, P0 ,?01 ,?02 , ?c1, and ?c2 were significantly longer or higher in R-0.0, 0.2 and 0.4 groups than those in control group. (2) There was no significant difference in the conductance, P0 , ?01 , ?02 , ?c1 , and ?c2, between R-0.5 and control group but those in R-0.0, 0.2 and 0.4 groups were significantly higher or longer than control group, when rocuronium was used with atropine. Conclusions AchR/channel ( muscarinic and nicotinic ) in cone neuron of hippocampal cortex were excited by different concentrations of rocuronium. The results suggest that adverse effect may be induced on CNS by rocuronium in case it permeates the injured blood-brain barrier.

Objective To investigate the effects of femoral nerve block combined with celecoxib on postoperative analgesia in elderly patients with hip fracture. Methods Two hundreds ASA -Ⅲ patients aged 65-89 yrweighing 35-90 kg undergoing hip fracture surgery were randomly divided into 4 groups ( n = 50 each):control group (group Ⅰ ), femoral nerve block group ( group Ⅱ ), celecoxib group (group Ⅲ ) and femoral nerve block +celecoxib group (group Ⅳ ). Operations were performed under combined spinal-epidural anesthesia. Groups Ⅲand Ⅳ were given oral celecoxib 400 mg at 1 h before operation, and 200 mg at 1 and 2 days after operation twice a day. Groups Ⅰ and Ⅲ received iv injection of sufentanil 0.06 μg/kg before the patients were placed in the position, while in groups Ⅱ and Ⅳ femoral nerve block was performed using a nerve stimulation with 20 ml of 0.5%ropivacaine and 10 min later the patients were placed in the position. All the patients received postoperative patient-controlled intravenous analgesia with sufentanil to maintain visual analogue scale score ≤ 3. The condition of satisfactory analgesia and sufentanil consumption within 24, 48 and 72 h were recorded. The coagulation function was measured on the day of admission to the hospital, at 1 day before operation and at 4 days after operation. Cardiac troponin Ⅰ (cTnI) concentrations were measured before operation, at the end of operation and at 1 day after operation. Postoperative complications was observed and recorded. Results Compared with group Ⅰ , the consumption of sufentanil was significantly reduced during each period in group Ⅳ ( P ＜ 0.01 ). Compared with group Ⅱ , the consumption of sufentanil was significantly reduced within 48 and 72 h after operation (P ＜ 0.05), while no significant change was found within 24 h after operation in group Ⅳ ( P ＞ 0.05). Compared with group Ⅲ , the consumption of sufentanil was significantly reduced within 24 h after operation ( P ＜ 0.05 ), while no significant change was found within 48 and 72 h in group Ⅳ ( P ＞ 0.05). The level of satisfactory analgesia was significantly higher in group Ⅳ than in the other three groups, and in groups Ⅱ and Ⅲ than in group Ⅰ ( P ＜ 0.05). The 4 groups were comparable with respect to the increased rate of cTnI concentrations at the end of operation and after operation, and perioperative blood coagulation. No postoperative complications were found in the 4 groups. Conclusion Femoral nerve block combined with celecoxib can reduce postoperative opioid consumption and enhance postoperative analgesia in elderly patients with hip fracture.
