Objective To analyze the efficacy and experience of coil embolization in patients with pulmonary arteriovenous malformations(PAMV). Methods Seven patients (2 males and 5 females, age range from 11 to 52 years; mean age 31 years) were admitted including 4 single saccular, 2 multiple saccular, 1 diffuse capillary pulmonary arteriovenous malformations. Results Coil embolization of pulmonary arteries was successful in all 7 patients. The mean arterial oxygen saturation rate increased from 87% to 96% in patients with saccular PAMV. Transient chest pain occurred in a case of diffuse capillary PAMV during the procedure, after undergoing multiple coil embolization, the arterial oxygen saturation rate increased from 79% to 87%. All patients were followed up for 6 months to 5 years, arterial oxygen saturation declined slightly,and mild to moderate tricuspid regurgitation was found by echocardiography only in the patient with diffuse capillary PAMV.Conclusion Coil embolization is an effective and safe method of treatment for saccular PAMV. But it is only a palliative therapy for diffuse capillary PAMV.

Objective To elucidate the efficacy and safety of transcatheter closure of secondary atrial septal defect (ASD) with Amplatzer septal occluder (ASO) in people over 50 years of age. Methods Retrospective comparison of 41 patients (14 males, 27 females) with ASD over 50 years of age ranging from 50 to 75(mean age 55.5?7.6, elder group) was conducted with 132 patients younger than 50 years(control group). After diagnosis of ASDs and evaluation of pulmonary artery systolic pressure and right atrial and ventricular dimensions by transthoracic echocardiography (TTE), all patients underwent transesophageal echocardiography (TEE) for complete assessment of ASD size, margins and anatomic relationship of the defect before closure of ASD. Each case was treated with ASO through the percutaneous transcatheter procedure under fluoroscopy and TTE or TEE. Early follow up(3 months) by echo was taken after the intervention. Results There was no difference of mean defect diameter measured by TEE and the balloon-stretched defect diameter of the ASDs between 2 groups. Pulmonary artery pressures in elder group were higher than those in younger group(P

Objective To assess the clinical efficiency , safety and potential advantages of autologous blood transfusion (ABT) drains compared with the closed-suction/no drainage. Methods Pubmed, Embase, Cochrane Library, CBMdisc, CNKI, VIP and WANGFANG were searched comprehensively. The statistical anal-ysis was conducted by using the Cochrane Collaboration review Manager 5.3.5. Results The pooled data of seventeen RCTs including a total of 1 993 patients showed that the patients in the ABT drainage group might benefit from the low rate of blood transfusion [ 16 . 59% and 37 . 47%, OR: 0 . 28 ( 0 . 14 ~ 0 . 55 ); 13 . 05% and 16.91%, OR: 0.73 (0.47 ~ 1.13), respectively]. The ABT drainage and the closed-suction drainage/no drainage have the similar clinical efficiency and safety length of hospital stay and wound infection on days 3 post-operative haemoglobin. Conclusion This systematic review provides the evidence that the ABT drainage offers a safe and efficient alternative to CS/no drainage with the lowered blood transfusion rate.

Objective To study the expression of aquaporin-4 (AQP-4) in core and marginal region of the contusion brain tissues from patients with severe traffic brain injuries. Methods Thirty patients with severe traffic brain injuries (frontal-temporal brain contusion) admitted into our department from January 2007 to July 2009 were enrolled in the study and divided into three groups according to the period from injury to operation, ie, 0-4 hours (Group A), 5-8 hours (Group B) and 9-12 hours (Group C). The tissue was collected from core and marginal regions of brain contusion in each group. Ten parts of normal brain tissues obtained from the cerebellum to gain good exposure of CPA region tumors were used as control. The expression of AQP-4 in the normal brain tissues and in the tissues from core and marginal region of brain contusion, with GAPDH used as a control. Results The expression of AQP-4 in the marginal region was distinctly higher than that in normal tissues and in the tissues from core region. The AQP-4 expression in the tissues of the core region was lower than that in normal tissues. Conclusions AQP-4 is highly expressed in the tissues from the marginal region early after injury in a time-dependent fashion. Low expression level of AQP-4 in the core region is possibly correlated with early damage of blood brain barrier and peripheral structures.

BACKGROUND:There are numerous clinical studies on comparing absorbable internal fixation system and titanium metal internal fixation system in maxilofacial fractures; however, the systematic reviews and Meta-analysis in this field are rare. OBJECTIVE:To compare the clinical effect of absorbable internal fixation system and titanium internal fixation system in maxilofacial fractures through systematic review and Meta-analysis. MATERIALS AND METHODS:The randomized controled trials and controled clinical trials regarding the application of absorbable internal fixation system and titanium internal fixation system in maxilofacial fractures were electronicaly retrieved from Medline, Embase, the Cochrane Central Register of Controled Trials, China Biology Medicine disc, and China Academic Journal Network Publishing Database using the keywords. Meta-analysis was conducted using Revman 5.3 software. RESULTS AND CONCLUSION:Thirteen clinical studies were included, and totaly 1 718 patients were involved. The Meta-analysis results showed that the removal rate of implants in the absorbable internal fixation system group was significantly lower than that in the titanium internal fixation group (P=0.000 2); there were no significant differences in the healing rate of fracture I stage, the incidence of insufficient fixation in fracture site and the incidence of long-term complications between these two groups. These results demonstrate that the efficiency and safety of absorbable internal fixation system in maxillofacial fracture is satisfactory, and can reduce the proportion of secondary surgical removal of the implant. More randomized controlled trials should be conducted to confirm this conclusion.

BACKGROUND: Total knee arthroplasty is a procedure for treatment of knee osteoarthritisa with standardized, mature technology and affirmative efficacy. Total knee arthroplasty can result in overt excessive bleeding, decreased hemoglobin levels, patient mouth infection and other complications. As a new technology, autologous blood transfusion device can effectively reduce the rate of blood transfusion through reinfusing the unwashed and filterable drainage blood after operation. Up to now, no systematic reviews incorporating meta-analyses have found directly sufficient evidence to compare autologous blood transfusion drainage and no drainage after primary total knee arthroplasty. OBJECTIVE: To study the clinical efficacy, safety and potential advantages of the application of autologous blood transfusion device/no drainage based on the meta-analysis. METHODS:PubMed, Embase, the Cochrane Library, CBMdisc, China HowNet, VIP, Wanfang database were searched comprehensively by computer. The search strategies were developed by the way of MeSH terms combining with free words: “total knee replacement” OR “total knee arthroplasty” OR “total knee prosthesis” OR “unicompartmental” OR “unicondylar” OR “unicompartmenta” OR “arthroplasty, replacement, knee” [MeSH terms] AND “autologous blood transfusion” OR “Autotransfusion” OR “blood transfusion, autologous” [MeSH Terms] OR “Intraoperative Blood Salvage” OR “Intraoperative Blood” OR “Postoperative Blood Salvage” OR “Intraoperative Blood Cel Salvage” OR “Operative Blood Salvage” [MeSH Terms]. Data included in the final literature were analyzed using RevMan 5.3.5 software recommended by Cochrane. The main outcome measure was the rate of transfusion. The secondary outcome measures were the average change in hemoglobin, hemoglobin levels at the 3rd day, hospitalization time and intraoperative mouth infection rate. RESULTS AND CONCLUSION:Five randomized controlled trials, a total of 667 patients were enroled. Meta-analysis results showed that there were no significant differences in the transfusion rate (OR=0.73, 95%CI: 0.47-1.13;Z=1.41,P=0.16), average change in hemoglobin (WMD=0.20, 95%CI:-0.28-0.68;Z=0.82,P=0.41), the hemoglobin levels at the 3rdday (WMD=0.41, 95%CI:-0.26-1.09;Z=1.20,P=0.23), hospitalization time (OR=1.01, 95%CI: 0.06-16.27;Z= 0.01,P=1.00), intraoperative mouth infection rate (OR=1.01, 95%CI: 0.06-16.27;Z=0.01,P=1.00) between the postoperative use of autologous blood transfusion and no drainage. These results suggest that the meta-analysis of outcome measures has not provided the evidence-based medical support for the clinical efficacy of autologous blood transfusion device (including blood transfusion rate, the average change in hemoglobin, average hemoglobin change at the 3rd day, hospitalization time). Given the inherent limitations of the quality of the included studies and the publication bias, future high-quality, large-volume, multi-center randomized controled trials are awaited to confirm and update the findings of this analysis.

BACKGROUND:Absorbable colagen membrane can be theoreticaly applied to secondary alveolar bone grafting in alveolar cleft surgery, which can improve the bone preservation and slow bone resorption. However, there is stil no unified conclusion.
OBJECTIVE:To assess the efficacy and safety of absorbable colagen membrane for secondary alveolar bone grafting viaa systematic review.
METHODS:MEDLINE, EMBASE, CBM and CAJD were searched for eligible articles addressing clinical randomized controled or controled trials of absorbable colagen membrane for secondary alveolar bone grafting. Test group received bone grafting with absorbable colagen membrane and control group only received bone grafting. Meta-analysis on the clinical success rate of bone grafting and incidence of complications in the recipient region was delivered with Revman 5.3.
RESULTS AND CONCLUSION:Five clinical trials, involving 416 cleft sites and 387 participants, were included. Two had high risk of bias and the rest had unclear risk of bias. If “the height of new bone is≥ 50% of alveolar height” was adopted as clinical success, the clinical success rate of the test group was significantly higher than that of the control group (P=0.002, relative risk value=1.33, 95% confidence interval [1.11, 1.60]). If “the height of new bone is≥ 75% of alveolar height” was chosen as clinical success, the clinical success rate of the test group was higher than that of the control group, but there was no significant difference between the two groups (P=0.06, relative risk value=1.40, 95% confidence interval [0.99, 1.99]). For safety, the use of absorbable colagen membrane could not increase the complications incidence (P=0.35, relative risk value=0.66, 95% confidence interval [0.28, 1.58]). So, the use of absorbable colagen membrane is safe to improve the clinical success rate of secondary alveolar bone grafting in alveolar cleft surgery. More randomized controled trials should be considered to reinforce the conclusion.
