40 cases of parotidectomy were reviewed.Anterograde approach(group A)and retrograde approach(group B)for facial nerve dissection were used in 1 7 and 23 cases respectively.1 patients in group A and 8 in group B presented symptoms of temporary facial nerve paralysis(P <0.05).The anterograde method is safer and quicker.

Objective To investigate the ultrasonographic manifestations of traumatic neuroma after neck dissection in papillary thyroid carcinoma (PTC).Methods A retrospective analysis was performed in 21 patients with 26 lesions who underwent neck dissection.The ultrasonographic characteristics were reviewed,including numbers,location,size,shape,margin,echogenicity,with or without direct continuity to the nerve fiber,the presence of internal hyperechogenicity and blood supply.Results Among the 26 lesions of 21 patients,25 lesions were in the lateral cervical area while the other one was in the central cervical area.The mean shortest diameter of the lesions was (3.5±1.0)mm and that of longest diameter was (9.1±2.9)mm.Totally 13 lesions were oval in shape and the other 13 were round.The clear margin was found in 13 lesions and fuzzy margin was observed in another 13 lesions.All the lesions were heterogeneously hypoechoic.The presence of internal hyperechoic areas were found in 16 lesions.The direct continuity with the nerve fiber was found in 20 lesions,while the other 6 lesions were not continued to the nerve directly.Color Doppler flow imaging showed that 20 of the 26 lesions existed a little blood flow signal and the other 6 lesions showed no flow signal.During the ultrasound-guided fine-needle aspiration biopsy (US-FNAB),21 patients complained about the intolerable serious pain and the pain relieved when the needle removed.Conclusion Traumatic neuromas are hypoecho lesions located in the operation area after neck dissection in PTC with distinctive ultrasonographic features,especially the direct continuity with the nerve fiber,as well as the clinical histories and sharp pain during US-FNAB,which can help to diagnose.

T polymorphism of TGF-?1 gene related with the degree of L_(4?5) and L_5S_1 disc degeneration.

Objective To explore the optimal power of experimental pancreatic endoscopic ultrasonography (EUS)-guided radiofrequency ablation (RFA) therapy.Methods Six healthy live minipigs were randomly divided into two groups according to random number table,which received RFA under EUS or in laparotomy.Each pig in each group was randomly allocated to received RFA at different power (5 W,10 W,15 W).The impedance was monitored and the time for each therapy was recorded.The width diameter of coagulation necrosis from RFA was measured by EUS and gross pathology.Results RFA was completed in all pigs smoothly with stable life signs and without complications.Gross and micro pathologic observation confirmed formation of coagulation necrosis lesions.The width diameter of lesions from EUS-RFA was similar to that from surgery RFA,both having a maximum value at 10 W power (11 nun VS 10 mm).Conclusion The optimal power of experimental pancreatic EUS-RFA in pig is 10W,which should be further explored for the clinical purpose.

There is a new research model named 'registry study/patient registry' in Western medicine, which could be referred to by Chinese medicine researchers, such as active safety surveillance. This article will introduce registry study from different aspects as the developing history, features, and application in order to inform Chinese medicine researchers of future studies.

97 cases of jaw bone fractures were treated with rigid internal fixation.16 cases had malocclusion postoperation.The etiology was analyzed and the prevention methods were proposed.Intermaxillary elastic traction or fixation and craniomaxillofacial fixation or craniomentum elastic traction were performed to treat the malocclusion.By this way,14 cases were cured.1 case was operated again to resume the normal occlusion,1 case received occlusal adjustment.Incomplete reduction,incorrect operative performance,deficiency of postoperative intermaxillary fixation and incorrect intermaxillary fixation were the main causes to malocclusion.So anatomic in time reduction,correct operative performance,intermaxillary fixation,application of craniomaxillofacial fixation or craniomentum elastic traction instead of intermaxillary fixation for some special cases are effective methods to correct postoperative malocclusion.

Objective According to the characteristics of skin defects in ankle and foot select the posterior lateral leg pedide skin flaps supplyed by different blood to repair,providing advice and reference.Methods Between January,2001 and December,2015,163 cases of soft tissue defects at the foot and ankle were treated in our department.①The sural neurovascular flap was used in 93 cases in ankle and foot defect.②The sural nerve nutritional vessel flap pediele with the perforating branch of the peroneal artery in 36 cases in ankle and foot defect.③The sural nerve nutritional vessel flap pediele with the perforating branch of the peroneal artery including sensory reconstruction in 16 cases in heel rejion defect.④Peroneal artery perforator flap in 10 cases in anterior ankle,lateral malleolus and posterior malleolus defect.⑤The use of the sural fasciocutaneous flap alonged with peroneal artery and perforators in 8 cases in dorsal foot defect.The donor site with skin graft.Results Of the 93 sural neurovascular flaps,8 had partial loss,which were cured after dressing.All the sural nerve nutritional vessel flaps pediele with the perforating branch of the peroneal artery survived.Sensory grading standard by UK Medical Research Council was used to evaluate the recovery of sensory function on the last follow-up.The sensory function recovery of heel region flaps with reconstruction of the sensory was between S0 and S1.All peroneal artery perforator flaps survived.One of the sural fasciocutaneous flap alonged with peroneal artery and perforators occurred distal epidermis,which were cured after dressing.All patients were followed up 6-50 months (mean 20 months).All patients had recoveryed walking function,and infection wound had no recurrence after surgery.Conclusion According to the location,size,severity and the injury of peripheral vascular,select the most simple,safe,minimal damage flap for the soft tissue defects at the foot and ankle.The right choice and the exact design can improve flap survival rate,and recieve good clinical results.

Objective: To study the effect of Shenxiong Xintong Pill(SXP) on cardiac hemodynamics. Methods: Parameters of cardiac hemodynamics were examined in anesthetic chest-opened dogs medicated with various doses of SXP. Results: After intraduodenal administration of SXP of 2.0g/kg, the coronary blood flow was raised, coronary resistance decreased, heart rate slowed and the left ventricular diastolic end pressure fallen in the dogs. No obvious changes were found in the contraction , works and ejection of left ventricle. Conclusion: The mechanism of SXP in relieving angina pectoris was probably related to the dilatation of coronary artery and increase of coronary flow with the increase supply of oxygen.

Gene chip is a research tool on molecular biology which can detect generous gene expression rapidly.The studies on gene chip of leiomyoma have revealed the changes of gene expression related to cell growth,proliferation,apoptosis,metabolism,angiogenesis,formation of extracellular matrix,cell differentiation and immunity.The article reviews the advance on gene chip of leiomyoma and approaches the pathogenesis of leiomyoma on molecular level.
