OBJECTIVETo evaluate the clinical outcomes and complications of Triple-Endobutton plates in treating Tossy type III acromioclavicular joint dislocation.

METHODSFrom January 2011 to January 2013,45 patients with Tossy type III acromioclavicular joint dislocation were treated with Triple-Endobutton plates. There were 35 males and 10 females with an average age of 30.5 (ranged from 19 to 60) years old. At the final follow-up, VAS, DASH, Constant-Murley criterion were used to evaluate shoulder function.

RESULTSAll patients were followed up from 15 to 36 months. No neurovascular injury, wound infection and stress fractures were found,but 3 patients had a re-dislocation. At the final follow-up,the mean VAS score was decreased from (5.7±1.6) preoperatively to postoperative (0.2±0.1); DASH score was significantly decreased from (19.6±4.3) preoperatively to (0.3±0.1) postoperatively; Constant-Murley score was improved from (34.4±4.3) before operation to (94.8± 3.5) after operation.

CONCLUSIONClinical outcomes of treating Tossy type III acromioclavicular joint dislocation with Triple-Endobutton plates is satisfactory. However, re-dislocation is still the most common complication. Careful perioperative management is an important factor in preventing re-dislocation.

Objective To evaluate the clinical effect of Wy 10 whitening combined with enamel microabrasion on bleaching dental fluorosis.Methods Forty patients with dental fluorosis were in-cluded and divided into two groups (20 each):group A was treated with Wy 10 whitening and enamel microabrasion,and group B only with Wy 10 whitening.Efficacy was measured according to the Vita classical shade guide before and after treatment.Sensitivity between groups was also tested.Results The effective rate of group A was significantly higher than that of group B (x2 =5.096,P＜0.05).The sensitive rates were 20.0％ (4/20) and 15.0％ (3/20) in group A and group B,respectively.No significant difference was found between the two groups in sensitivity (P＞0.05).Conclusions Wy 10 whitening combined with enamel microabrasion is an effective and safe method for bleaching dental fluorosis.

The treatment of diabetic nephropathy (DN) currently extent to control the occurrence and development of it and delay renal failure on a certain stage.However,the effect is not satisfactory.Some traditional hypoglycemic,antihypertensive,lipid and anticoagulant drugs in DN patients with renal protective effect.And some have been in clinical use of drugs such as vitamin D,aldose reductase inhibitors,tripterygium wilfordii glycoside has proved to have the effect of the slow progress in DN,could be used more widely.For new drugs,such as renin inhibitors,phosphodiesterase inhibitors and methyl bartholomew sauron,while partialy was confirmed in a role in the treatment of DN,but before the clinical promotion,its effectiveness and safety still need further study to verify.

Objective: : To investigate whether development of the sph e noid sinus affect the surgical approach via saddle area. Methods: The pneumatization of sphenoid sinus of 50 cadaver heads was studied through t hinner CT scanning of coronal, sagittal and axial position. The sphenoid sinus w as classified according to the degree of pneumatization of sphenoid sinus toward s sphenoid bone, small wing of sphenoid bone and epippium. Results: There were 4% conchal, 18% pre-sellar, 18% semi-sellar, 14% sellar, 46% sellar -occipital in 100 sphenoid sinus cases. The transversal diameter of left and ri ght was 18.48 mm and 17.58 mm; The sagittal diameter of left and right was 2 2.20 mm and 20.82 mm, The vertical diameter of left and right was 21.02 mm and 2 0.38 mm. The distance between centre track and the later wall of sphenoid sinus was 14.78 mm in left side and 15.18 mm in right side. Conclusion: Thinner CT scanning with coronal and sagittal position can clearly show pneum atization of sphenoid sinus on both sides. Different pneumatization of sphenoid sinus provide anatomical basis for choosing operation approach.

Objective:To investigate the value of proton magnetic resonance spectroscopy (1H-MRS) on the diagnosis of SCA3/MJD,and to calculate the correlation between 1H-MRS ratio and the clinical score.Methods:Sixteen patients with SCA3/MJD and 19 healthy volunteers were scanned with 1H-MRS.The data of N-acetyl aspartate,creatine,choline-containing compounds,myoinositol,NAA/Cr,Cho/Cr,and mI/Cr ratio were collected,which were grouped for comparative study.The onset patients with SCA3/MJD were evaluated with the International Cooperative Ataxia Rating Scale and Scale for the Assessment and Rating of Ataxia,the correlation between NAA/Cr,Cho/Cr or mI/Cr ratio and the clinical score was calculated.Results:The NAA/Cr in the pons and cerebellar dentate nucleus from the onset patients with SCA3/MJD was significantly reduced compared to that in the normal control group.The NAA/Cr in the cerebellar dentate nucleus of onset patients with SCA3/MJD was obviously correlated with ICARS.Conclusion:SCA3/MJD lesions are mainly located in the cerebellum and brainstem,where gray and white mater are also involved.The cerebellar dentate nucleus may be the earliest involved area.There is a correlation between the ICARS and the cerebellar lesion degree.The ICARS reflects the severity of clinical manifestations.1H-MRS is useful in the diagnosis of SCA3/MJD.

ObjectiveTo compare the efficacy of ropivacaine-lidocaine carbonate mixture versus equivalent ropivacaine for retrograde infraclavicular brachial plexus block.MethodsSixty ASA Ⅰ or Ⅱ patients of both sexes aged 18-64 yr weighing 49-98 kg undergoing elective upper limb surgery with ultrasoumd-guided retrograde infraclavicular brachial plexus block were randomly assigned into two groups ( n ＝ 30 each):group A 0.35％ ropivacaine 30 ml and group B 0.233％ ropivacaine mixed with 0.346％ lidocaine carbonate 30 ml.Sensory (by pinprick test) and motor block (by Bromage scale) were assessed every 5 min after block.The onset time of sensory and motor block of each brachial nerve,the effective rate of sensory and motor block at 30 min after brachial plexus block and complications were recorded.ResultsThere was no significant difference in the onset time of sensory and motor block of each brachial nerve and the effective rate of sensory and motor nerve block between the 2 groups.No severe complication occurred in either group.ConclusionsThe efficacy of retrograde infraclavicular brachial plexus block with ropivacaine-lidocaine carbonate mixture and equivalent ropivacaine is similar suggesting that lidocaine carbonate does not enhance the anesthetic efficacy.
