Objective To evaluate the efficacy and clinical feasibility of the computer-assisted full plan- ning system for tibial fracture treatment with intramedullary nailing.Methods After analyzing the functional structure and operative procedures of the system,nine plastic tibia and 12 cadaver lower limbs were used for image mosaicing based on C-arm (PHILIPS BV Libra) fluoroscopic images in the operation room to assess the correctness of the mosaicing and planning algorithms.The plastic tibial model was used for analysis of the mosaicing precision.The cadaver tibial bone was used for reduction experiment with the reduction mechanism to analyze the operation feasi- bility.Results Only 7 to 10 [fluoroscopy time:(19.75?0.61)s] valid C-ann projection images were needed to produce a long bone panorama of the lower limb.The total time for image acquisition and mosaicing was within (4.17?0.86)minutes and the mosaicing precision in the plastic tibial model was (1.26?0.76)mm.The opera- tion of the reduction mechanism was very simple and could be controlled by a surgeon automatically or free of hand. An integrated reduction strategy could be produced for rough positioning in general and elaborate operations in de- tails.Conclusion The computer-assisted full planning system can be used for anatomical analysis based on the C-arm panorama,full surgical planning,virtual simulation,selection of proper intramedullary nails and fracture reduction in treatment of long bone fractures.

Cardiac surgery carried out on cardiopulmonary bypass(CPB) in a pregnant woman is associated with poor neonatal outcomes although maternal outcomes are similar to cardiac surgery in non-pregnant women.Most adverse maternal and fetal outcomes from cardiac surgery during pregnancy are attributed to effects of CPB.The CPB is associated with utero-placental hypoperfusion due to a number of factors,which may translate into low fetal cardiac output,hypoxia and even death.Better maternal and fetal outcomes may be achieved by early pre-operative optimization of maternal cardiovascular status,use of perioperative fetal monitoring,optimization of CPB,delivery of a viable fetus before the operation and scheduling cardiac surgery on an elective basis during the second trimester.

Objective The prosthesis used for aortic valve replacement (AVR) can be too small in relation to body size,thus causing valve prosthesis-patient mismatch (PPM).The aim of this article was to summarize the preventive strategy of PPM during AVR.Methods A total of 357 patients [203 males,154 females; mean age (54.9 ± 18.7 ) years ] underwent AVR between February.2010 and December 2011.The weight and body surface area (BSA) of the group is( 60.1 ± 11.4 )kg and (1.67 ± 0.21 )m2 respectively.The aortic valve prosthesis effective orifice area (EOA) was divided by body surface area (BSA) to obtain the EOA index (EOAI).PPM was then defined as none or mild if EOAI was ＞ 0.85 cm2/m2,as moderate for (0.65 - 0.85 ) cm2/m2 and as severe for ＜ 0.65 cm2/m2.To avoid PPM,a simple three-step algorithm was applied:Step 1,Calculate the patient's BSA from weight and height;Step 2,Calculate the minimal valve EOA required based on the BSA to ensure an EOAI ＞0.85 cm2/m2 ; Step 3,Select the type and size of prosthesis that has reference values for EOA greater or equal to the minimal EOA value obtained in step 2.For patients with a small aortic root,the following three methods was used:( 1 ) Replace aortic valve with simple interrupted suture technique ; (2) Apply new type and high-performance prosthetic valves such as St.Jude Medical Regent mechanical valve ; (3) Enlarge the narrowed aortic root when necessary.Results Of all 357 patients,272 patients received mechanical AVR and 85 bioprosthetic AVR.Among the 49 patients who received AVR with simple interrupted suture technique.St.Jude Medical Regent mechanical valve was implanted in 38 patients and the aortic root enlargement was performed in 11 patients.The total prevalence of PPM was 6.4％ and there was no severe PPM.The prevalence of PPM with mechanical AVR and bioprosthetic AVR was 1.8％ and 21.2％ respectively.There were 4 deaths during early period of operation,and the operative mortality was 1.1％.Conclusion Prosthesis-patient mismatch can be effectively prevented at the time of AVR with appropriate measurement.

The effects of subclinical epileptiform discharges (SEDs) on children with cerebral palsy cannot be ignored. Data from neurodevelopmental clinic studies showed that the overall incidence of SEDs in cerebral palsy was 18%～40%, with the highest in spastic hemiplegia and diplegia. The major pattern of SEDs was focal and multifocal, and was usually found in centro-temporal and parietal regions. The cortex impairment and other complications were risk factors related to SEDs in cerebral palsy. Paroxysmal or frequent long-time SEDs, with the Results of transient or chronic cognitive impairment, have been found to lead to subsequent death of cortical neurons of cerebral palsy patients thereby worsening their prognosis. Valproic acid (VPA), benzodiazepines (BZs) and lamotrigine (LTG) have a role in inhibiting SEDs, while adrenocorticotropic hormone (ACTH) and glucocorticoids have a great role in it.

Objective To explore the anti-apoptotic mechanism of Roux-en-Y gastric bypass (RYGB) through exam?ine the postoperative change of adiponectin levels and expressions of pancreatic islets relative apoptotic protein. Methods Sixty SD rats were randomly allocated to RYGB group (n=20), type 2 diabetes mellitus group (T2DM, n=20) and normal con?trol group (NC, n=20). Rats in the NC group were fed with normal diet. In order to make type 2 diabetic rat models, the rats in the T2DM and RYGB groups were fed with high fat diet (22.19 kJ/g) combined with administration of intraperitoneal strep?tozotocin injection (STZ, 30 mg/kg) on the 13th day of high fat diet. RYGB operation were performed in RYGB group and sham-operation were performed in the T2DM and NC groups when diabetic model was contructed. Rats were weight preoper?atively and at the 7th, 14th, 21st days after operations. Fasting plasma glucose and adiponectin (ELISA) were measured preoper?atively and at 21st day postoperatively. Protein expressions of Bcl-2,Caspase 8 and Caspase 9 in pancreatic islets were ex?amined by immunohistochemistry at the 21st day postoperatively. Results Body weights do not vary significantly among three groups preoperatively. Compared to rats in the NC group, fast plasma glucose level was higher but adiponectin was low?er in rats in RYGB and T2DM groups. Body weights of rats in RYGB group decreased significantly compared to those of rats in NC and T2DM groups postoperatively. Compared to rats in T2DM group, fasting glucose level was lower while adiponectin concentrations was higher in rats in RYGB group but no differences of these parameters were seen in rats in NC group at the 21st day postoperatively. Expression of Bcl-2 in RYGB group was significantly elevated while expressions of Caspase 8 and Caspase 9 were significantly decreased compared to those in T2DM group postoperatively. Conclusion Adiponectin levelswas elevated;expressions of Bcl-2 was increased;expressions of Caspase 8, Caspase 9 were decreased upon RYGB opera?tion in T2DM model. RYGB might reduce pancreatic islets apoptosis through mitochondrial pathway.

Objective To investigate the value of mammography (MAM),ultrasound (US)and MRI in the diagnosis of breast tumors using a Meta-analysis.Methods A systematic search of relevant literatures was done from CNKI,CBM,VIP,EMBASE OvidSP,PubMed and The Cochrane Library databases.Some related literatures about MAM,US and MRI in the diagnosis of breast tumors and the quality was evaluated,and the available information was extracted.The Meta-analysis was then performed by a Meta-disc 1.4 software,and a Review Manager 5.3 software was used to calculate the summary receiver operating characteristic curves and the area under the curve.Results The diagnostic effect of the MAM+US+MRI was significantly higher than that of mammography or ultrasound (P <0.05).The MAM study heterogeneity among sources was affected by whether it based on BI-RADS diagnostic criteria,and US study heterogeneity was affected by average age of patients.However,the MRI heterogeneity between studies displayed by regression analysis was not affected by each covariate.The diagnostic sensitivity and specificity were 76% (95%CI:0.73-0.79)and 72% (95%CI:0.69-0.75)for MAM,85% (95%CI:0.82-0.87)and 70% (95%CI:0.67-0.73)for US,and 95% (95%CI:0.93-0.96)and 72% (95%CI:0.69-0.75)for MRI,respectively.And the area under curve (AUC)of summary receiver operating characteristic (SROC)curve was 82.0%,88.5% or 97.4%, respectively.Moreover,the AUC of combined three methods together was 98.3%.Conclusion The value of MAM,US and MRI in diagnosis of breast tumor is higher,and the highest one exists when the combined three methods together are used.
