Objective To explore the cause, clinical feature, rescue measures and prognosis of tracheo-innominate artery fistula (TIF). Methods From January1995 to January 2015, there were 621 patients who were performed tubotomy, and 8 patients had TIF. The diagnosis of TIF were established by surgery exploration or autopsy. Results The interval between tracheostomy and TIF was 8- 78 d. Before TIF, hemoptysis occurred in 4 patients. When TIF occurred, bedside aid was performed and 4 patients quickly died of asphyxia because of massive blood in the trachea. The others lived long enough to reach the operating room. The family of 1 patient refused surgical therapy and he eventually died. Three patients accepted median sternotomy. One patient underwent vascular repair and died after surgery because of infection in repaired area. The other patients accepted ligation of the innominate artery without suction drains in the mediastinum and died after surgery because of re-bleeding due to mediastinal infection. The last one patient underwent ligation of the innominate artery with suction drains in the mediastinum, and was still alive without long-time neurological complications and re-bleeding after a follow-up of 14 months. Conclusion A prompt diagnosis and surgical intervention can save the life of TIF patient. Prevention is very vital because of the high mortality of this disease.

Rectal cancer is a common malignancy in the alimentary tract with an increasing incidence, the current treatments of which include surgery, radiotherapy, chemotherapy, and integrated comprehensive options. Sexual dysfunction, especially erectile dysfunction (ED), is one of the commonest complications in men after rectal cancer treatment and is generally attributed to the damage to the pelvic autonomic nerves. However, recent studies show that ED after rectal cancer treatment is a complex pathophysiological process associated with neurogenic, vasculogenic, and psychological factors. This article reviews the pathogeneses of ED after rectal cancer treatment in order to provide some theoretical evidence for its prevention and treatment.

Objective To investigate the clinical values of extracapsular invasion at sentinel lymph nodes in patients with breast cancer.Methods From Jan,2010 to Jan,2013,80 patients underwent axillary lymph node dissection due to sentinel lymph nodes invasion were enrolled in this prospective study.Patients were signed to extracapsular at sentinel lymph nodes positive group (n =45)and control group (n =35)according to the intra -operative pathology.The primary outcome was rate of positive non -sentinel lymph nodes and the second outcomes were 3 -year recurrence -free survival,mortality and health -related quality of life.Results Compared with the control group,the patients in extracapsular at sentinel lymph nodes positive group got a significantly higher rate of positive non -sentinel lymph nodes (91.11% vs.28.57%,χ2 =33.321,P <0.001 );a significantly lower rate of 3 -year recurrence -free survival(57.78% vs.88.57%,χ2 =9.114,P =0.003);a significantly higher rate of mortality (17.78% vs.2.86%,χ2 =4.390,P =0.036);and a significantly lower level of health -related quality of life[(78.43 ±12.43)vs.(87.54 ±11.89),t =11.324,P =0.000].Conclusion Extracapsular invasion at sentinel lymph nodes was a reliable predictor for non -sentinel lymph nodes invasion and long -term clinical outcomes.

OBJECTIVETo explore the relationship of the classification of talus fracture and surgery methods with avascular necrosis.

METHODSFrom March 2009 to November 2013, 78 patients with talus fracture were treated, of them, 43 cases were followed up from 2 to 5 years. There were 27 males and 16 females, aged from 17 to 65 years old with the mean of 38.6 years. Thirty-nine cases had talar neck injury and 4 cases had talar body injury. Different treatments were performed according to different injury conditions. The time from injury to treatment was from 6 to 48 hours. The effect of classification of talus fracture and surgery methods on avascular necrosis was analyzed.

RESULTSIn 43 cases,19 cases occurred avascular necrosis, including talar neck fracture of type I in 2 cases, type II in 5 cases, type III in 5 cases, type IV in 5 cases and talar body fracture in 2 cases (combined with talar neck fracture). And 29 patients were treated with operation, there was no statistically significant differences in avascular necrosis with different operations.

CONCLUSIONCompared with talar body fracture, talar neck fracture is more easily to develop into avascular necrosis. In the 4 types of talar neck fracture, the possibilities of type III and IV were the most ones.

Purpose To investigate the diagnostic value of the arrhythmogenic right ventricular dysplasia (ARVD) using multi-slice spiral CT (MSCT). Materials and Methods Thirty-four patients who were suspected as ARVD received right ventricular radiography, including 16 ARVD patients and 15 non-ARVD patients regarded as control group. The structural and shaped change of heart on reconstructed images of long axis, short axis and four cavity surface and analyze were observed, and MSCT features of right ventricular radiography characteristics were analyzed for ARVD patients. Results Sixteen cases of ARVD were correctly diagnosed by MSCT, and 14 cases had fatty infiltration including 11 cases of apex of heart, 8 cases of inferior wall, 5 cases of anterior wall, 5 cases of anterior wall of funnel area, 3 cases of diagram, 4 cases of papillary muscle, 6 cases of muscular trabecula and moderator band and 1 case of whole right ventricular free wall. Five cases showed scallop sign, 16 cases excessive trabecular change, 11 cases thinned changes, and 16 cases enlarged changes of right ventricular wall. Conclusion MSCT features of right ventricular for ARVD have relative diagnostic characteristics, and the scallop sign and excessive trabecular change of right ventricular wall are its specific imaging characteristics.

Frogs were caught from 4 towns in Huaxi of Guiyang and dissected.The collected spargana were used to infect young dogs for species identification.Results showed that the wild frogs were identified as Rana nigromaculata, and the infection rate was 16%(131/818) with an average intensity infection of 3.44 per frog, The tapeworm obtained from an infected dog was specified as Spirometra mansoni.

Objective To investigate the effect of salidroside on brain edema and neurological function in global cerebral ischemia-reperfusion injury in rats.Methods A total of 100 Sprague Dawley rats were randomly divided into sham operation,ischemia-reperfusion and salidroside 12,24 and 48 mg/kg groups (n =20 in each group),and than redivided into 6 h,24 h,72 h and 7 dsubgroups (n =5 in each subgroup).A rat model of global cerebral ischemia was established using the four-vessel occlusion method.Immediately after modeling,all groups were administered intragastrically for 7 days.The brain water content was quantitated by the wet-dry weight method.The neurological evaluation was performed using a neurological deficit score (NDS).Results After modeling both the ischemia-reperfusion group and all the salidroside groups had significant neurological deficit,and as time went by,it was improved gradually.Compared to the ischemia-reperfusion group at the corresponding time points,neurological deficit in all the salidroside groups was improved significantly (all P ＜ 0.05),and showing a dose-dependent trend.Compared to the salidroside 12 mg/kg and 24 mg/kg groups,neurological deficit in the salidroside 48 mg/kg group was improved significantly at 72 hours and 7 days (all P ＜ 0.05).The brain water contents began to increase at 6 hours after modeling in the the ischemia-reperfusion group and all the salidroside group.They reached the peak at 72 hours,and significantly higher than that in the sham operation group (all P ＜ 0.05).The brain water contents in all the salidroside group were significantly lower than those in the ischemiareperfusion group at 24 and 72 hours after modeling (all P ＜ 0.05) and showing a dosedependent trend.The brain water content in the salidroside 48 mg/kg group was close to that in the sham operation group at 7 days after modeling.Conclusions Salidroside may significantlydecrease brain edema and improve neurological function in global cerebral ischemia-reperfusion injury in rats,and it has a neuroprotective effect.
