model control group. CONCLUSION: Both heterologous bone marrow stem cell transplantation and vascular endothelial growth factor injection can promote the formation of retroperitoneal blood vessel in rats with portal hypertension, and the conbination of them can effectively relieve portal venous pressure.

Objective The tumor-bearing (S37) mice were used to study the effects of acupuncture and moxibustion on relative network of IL2-IFN-NKC regulatory network. Methods After puncturing and (or) igniting the acupoints of Dazhui (Du 14) and Houhai(Du 1), we observed its effects on MФ,IL1 ,Th and tumor S37 by means of MФ devouring neutral red test,MTT colorimetry and Anti-L3T4 McAb-SPA rosetle test simultaneously. Results The phagocytic power of MФ in the mice's abdomen,the amount of IL1 and percentage of L3T4 increased obviously,compared to that of the control group;excepted the acupuncture group ,the other two experimental groups had the obvious inhibition to the tumor S37. In addition,the IL1 content increased remarkably in acumoxi group and moxibustion group than in acupuncture group. The percentage of L3T4 increased remarkably in acumoxi group than that in acupuncture group. Conclusion Applying both acupuncture and moxibustion at points of Dazhui (Du 14) and Houhai (Du 1) can make positive regulation on the relative MФ-IL1-Th network of IL2-IFNNKC regulatory network and has anti-tumor effect. The moxibustion also has the similar effects.

Objective To evaluate the causes of complications of patients with femoral Intertrochanteric fractures after gamma3 nail fixation.Methods A retrospective analysis was conducted to summarize the treatment of intertrochanteric fractures in 186 cases with Gamma3 nail from May 2006 to July 2011.Complications occurred in 24 cases during the operations.19 were males,5 females,with the age from 42 to 81,the average age of 69.00±3.27 years.According to AO/OTA classification,8 cases were type A1,1 case were type A2.1,15 cases were type A3.All patients included were acute fractures,while pathological fractures were excluded.Supine position were selected during operation,close reduction were performed in traction bed.Gamma3 nail made by Stryker Company was used to fix fractures through small incisions.Operational times were from 45 to 160 minutes,averaged by 80 min.Blood lose were 300-800 ml in average.No patient need blood transfusion.The procedure from hospitalized to operation is from 3 to 12 days,6 days in average,discharged from 3 to 16 days after operation.According to the intraoperative and postoperative follow-up evaluation of the X-ray and Harris evaluation criteria,Gamma3 nail complications were summarized in the application.Results Time of surgery in 24 cases were 45-160 min,average 80 min.Blood loss were 300-800 ml,average 600 ml,walking time 35-106 d.Harris evaluation were 75-91 point,average 81 point.The anti-spiral nail dropped into inner thigh muscles occurred in 1 case,causing defects of femoral lateral wall in 3 cases.Splitting fractures occurred in the proximal femoral shaft during the operations in 5 cases,poor fracture reduction during closed reduction in 6 cases.Fracture site were shifted lately postoperative in 5 cases,lag screw cut-out in 3cases and refracture in the site of distal femoral interlocking nail in 1 case.Conclusion Higher incidence of complications were occurred in some special types of AO classification when using close reduction and short Gamma3 nail.The reduction method,wrong indication selection and unreasonable application of equipment may result in the occurence of complications.We,therefore,should use long or short Gamma nail according to their respective induction method and scope of its application,aiming to avoid complications.

Objective To investigate the clinical characteristics and outcomes of ipsilateral talar and calcaneal fractures.Methods From April 2003 to July 2011,22 patients with ipsilateral talar and calcaneal fractures were treated in our hospital.There were 20 males and 2 females with an average age of 30.2 years (range,17 to 51 years).The fractures occurred on the left side in 10 patients and on the right side in 12 patients.There were 8 cases of talar neck fracture,including 3 type Ⅰ,3 type Ⅱ and 2 type Ⅲ according to the Hawkins classification; there were 14 cases of talar body fracture,including 6 type Ⅱ,2 type Ⅲ and 6 type V according to the Sneppen classification.There were 13 cases of extra-articular calcaneal fracture and 9 cases of intra-articular fracture.Four patients had open fractures,including 1 type Ⅰ,2 type Ⅱ and 1 type llⅢA according to the GustiloAnderson classification.The average time from injury to surgery was 5.5 hours for patients with open fracture and 11 days for patients with close fracture.Seventeen patients underwent internal fixation and 5 patients underwent non-operative treatment.Results All patients were followed up for 25 to 89 months (average,41.5 months).Skin necrosis of the edges of the incision was found in 2 cases and wound infection in 1 case.No fracture nonunion and loss of reduction were observed in all patients.At final follow-up,the functional results were assessed according to the AOFAS score,and the average AOFAS score was 78.9 (range,53 to 95).The result was excellent in 5 patients,good in 10 and fair in 7,and the overall excellent or good rate was 68.2％.Traumatic arthritis was found in 12 patients who had undergone surgical treatment,including 5 cases in subtalar joint and 7 cases in ankle and subtalar joint.Diaz disease occurred in 1 patient who had undergone non-operative treatment.Conclusion Ipsilateral talar and calcaneal fracture is a complicated injury which has many fracture types.The fractures should be reduced anatomically,and traumatic arthritis is the most common complication.

Objective To discuss external fixation method for the complex diaphyses fracture involving condyles of femur and evaluate its clinical efficacy.Methods A retrospective study was done on 42 patietns with comminuted femur diaphyses fracture combined with distal intra-articular fractures treated surgically from January 2001 to Janurary 2007.There were 24 males and 18 females at mean age of 33 years (20-66 years).According to AO/ASIF classification,there were 18 patients with type C2 fractures and 24 with type C3 ones.Simple internal fixation plus external fixation was performed on patitents with C3 fractures but only external fixation on those with C2 fractures.Four patients were treated with intramedular fixation.Results All patients were followed up for 1-12 months.According to Kotmert's assessment standard on function of proximal femur,the knee function was satisfactory in 35 patients (83% ) ,good in six (14% ) and unsatisfactory in one (2% ).Conclusions Minimally invasive external fixation can utmostly restore relative length of the femur and regulate between articular face of the femur and longitudinal axis of femur shaft to reach a symmetrical relation with middle and inferior part of opposite femur.Postoperative exercise is important for maximal recovery of the knee function.Attention should be paid to reconstruction of tubiform structure of the femur.

The posterior malleolus plays an important role in the stability and function of the ankle joint. Approximately 7%to 44%of ankle joint fractures are accompanied by posterior malleolus fractures. The current published data suggest a poor outcome for ankle fractures involving the posterior malleolus. Inappropriate reduction of the posterior malleolus fragment may re?sult in symptomatic malunion requiring corrective osteotomy. The posterior malleolus fractures were categorized into three types by Haraguchi:the posterolateral?oblique fractures (Type I), the transverse medial?extension fractures (Type II) and the small?shell fractures (Type III). Mangnus divided posterior malleolus fractures into two basic types: posterolateral and posteromedial types. Bartonícek classified the posterior malleolus fractures into four types on the basis of CT scan and 3D reconstructions, and taking into account the location, shape, size of the fragment and the integrity of the fibular notch:extraincisural fragment with an intact fibular notch (Type I), posterolateral fragment extending into the fibular notch (Type II), posteromedial two?part fragment involving the medial malleolus (Type III) and large posterolateral triangular fragment (Type IV). The fracture lines associated with posterior malleolus fractures appear to be highly variable. So far, no generally accepted clinically relevant classification of posterior malleo?lus fractures exists, and the indications of the operative management of these fractures were often determined by the size of the fragment. The anteroposterior and lateral views were used to evaluate the fractures of the fibular and the medial malleolus, as well as the rupture of the ligament and the presence of subluxation or dislocation of the talus. The determination of proper surgical ap?proach and the internal fixation should take into account the size, shape and displacement of the posterior fragment by CT scans, through CT and 3D reconstructions. The aim of treatment for posterior malleolus fractures is to reduce the displaced fragments ana?tomically, and to restore the stability of the tibiotalar joint and the distal tibiofibular syndesmosis.

Objective: To investigate the preventive effect of alprostadil (prostaglandin E1) combining hydration therapy on contrast induced nephropathy (CIN) after percutaneous coronary intervention (PCI) in elder patients. Methods: A total of 175 patients with coronary artery disease (CAD) elder than 75 years received PCI in our hospital from 2011-03 to 2014-03 were retrospectively studied, those including 122/175 (69.71 %) with male gender. The patients were at the mean age of (74.7 ± 3.9) years and randomly allocated into 2 groups: Control group, based on routine treatment, the patients received regular hydration of intravenous normal saline 1 ml/(kg?h) at 6 hours prior and 12 hours after PCI,n=84 and Alprostadil+hydration group, based on routine treatment and regular hydration, the patients received intravenous alprostadil 10μg in 100ml normal saline twice a day at 1 day prior PCI and the 3rd day after PCI,n=91. The serum levels of creatinine (SCr) were examined prior PCI and 3 days continuously after PCI, creatinine clearance rates (Ccr) were calculated and the CIN occurrence rates were compared between 2 groups. Results: At the 3rd day after PCI, the mean SCr level in Alprostadil+hydration group (92.08 ± 21.65) μmol/L was lower than Control group (99.43 ± 22.77) μmol/L,P<0.05, the mean Ccr level in Alprostadil+hydration group (63.78 ± 20.58) ml/min was higher than Control group (57.09 ± 22.31) ml/min,P<0.05. The occurrence rate of CIN after PCI was higher in Control group (13.1%, 11/84 patients) than Alprostadil+hydration group (3.3%, 3/91 patients),P<0.05. Conclusion: Alprostadil combining hydration therapy may obviously protect renal function and reduce the incidence rate of CIN in elder CAD patients after PCI treatment.

Objective: To observe the protective effect of ischemic post-conditioning on myocardial reperfusion injury with the potential mechanism in experimental rabbits. Methods: A total of 36 healthy New Zealand rabbits were divided into 6 groups:①Sham group,②Ischemic reperfusion control (CON) group,③Myocardial ischemic post-conditioning (MpostC) group,④Remote ischemic post-conditioning (RPostC) group,⑤MPostC+5-HD group,⑥RPostC+5-HD group.n=6 in each group. The ischemic reperfusion injury model was established by left ventricular descending artery occlusion for 45 min followed by reperfusion for 120 min. Bilateral external iliac artery was occluded for 5 min to induce the short skeletal muscle ischemia. The indexes of cardiac function and plasma CK , LDH activities were measured at baseline, end of ischemia and 1, 2 h after reperfusion respectively, the sizes of myocardial infarction (MI) were examined and compared among different groups. Results: ①Compared with CON group, the indexes of cardiac function were improved in MPostC and RPostC groups at 1, 2 h after reperfusion,P<0.05, and compared with MPostC group and RPostC group, the indexes of cardiac function were improved in MPostC+5-HD and RPostC+5-HD groups,P<0.05.②Compared with CON group, plasma CK, LDH activities were decreased in MPostC and RPostC groups at 2 h after reperfusion,P<0.05, and compared with MPostC group and RPostC group, the CK, LDH activities were increased in MPostC+5-HD and RPostC+5-HD groups,P<0.05.③The ischemic ranges and areas were similar between CON group and the other 5 groupsP>0.05. The MI ranges and areas in MPostC and RPostC groups were much less than that in CON group,P<0.05, and compared with MPostC group and RPostC group, the MI ranges and areas increased in MPostC+5-HD and RPostC+5-HD groups,P<0.05. The MI ranges and areas were similar between CON group and MPostC+5-HD, RPostC+5-HD groups,P>0.05. Conclusion: Classical ischemic post-conditioning and remote organ ischemic post-conditioning both have protective effect on myocardial reperfusion injury in experimental rabbit, which might be related to the activation of mitochondrial ATP-sensitive potassium channels.
