OBJECTIVETo investigate the clinical effects of double-plating internal fixation for the treatment of medial tibial plateau fractures with fracture-dislocation type through combined anterior and inverted "L" posteromedial knee approaches.
METHODSFrom February 2010 to September 2013, 17 patients with medial tibial plateau fractures with fracture-dislocation type were treated by double-plating internal fixation at our department. Anterior knee approach was adopted for medial mass reduction and fixation,while the inverted "L" posteromedial approach was used for posteromedial mass. There were 11 males and 6 females, with an average age of 42 years old (ranged, 21 to 65 years old). The efficacy were investigated by comparing pre- and post-operative radiographic data, and by evaluating clinical symptoms using the HSS score system.
RESULTSAll the patients were followed with a mean time of 18 months (ranged, 11 to 25 months). The tibial-plateau varus angle immediately after operation and at the latest follow-up were respectively (87.8 ± 4.2)° and (88.2 ± 4.6)°, and there was no statistical difference (P = 0.458). The posterior slope angle immediately after operation and at the latest follow-up were respectively (10.1 ± 3.7)° and (10.3 ± 4.1)°, and there was no statistical difference (P = 0.512). The knee joint HSS score was 86.7 ± 6.1. No patient had complications such as infection, skin necrosis, internal fixation loosening or loss of fracture reduction.
CONCLUSIONDoubl-plating internal fixation through combined approaches is an ideal operation method for medial tibial plateau fractures with fracture-dislocation type, because it can provide clear surgical field, satisfactory reduction, reliable fixation, and chance for early functional exercise.

With the development of tissue engineering,the bone tissue engineering is developing rapidly. Engineering hone typically uses an artificial extracellular matrix (scaffold),osteoblasts or progenitors,and os- teoinductive factors which promote cell attachment,differentiation,and mineralized bone formation.Highly porous scaffolds play a critical role in cell seeding,proliferation,and new 3D-tissue formation.A variety of biodegradable polymer materials and scaffolding fabrication techniques for engineering bone have been developed over the past decade.This article reviews the scaffold design and fabrication methods tor engineering bone to analyze their ad- vantages and limitations.Various architectural parameters of scaffolds important for bone tissue engineering (e.g. porosity,pore size,interconnectivity) are discussed.

Objective To investigate the influence of high intensity focused ultrasound(HIFU) ablation therapy on pregnancy outcomes in the patients with adenomyosis(AM).Methods Twenty patients with AM and successful pregnancy after HIFU ablation in Chongqing Haifu Hospital from April 2011 to February 2016 were selected.Their pregnancy and delivery situation were retrospectively analyzed.Results After HIFU treatment,the symptoms of dymenorrhea and menorrhagia were significantly improved compared with before operation(P<0.05).The average fertilization time after HIFU was(8.75 ± 6.23) months,among them 11 cases succeeded in delivery,5 cases had spontaneous abortion,1 case was ectopic pregnancy,1 case took artificial abortion and 2 cases were still in pregnant period all cases had no uterime rupture during pregnant or delivery period.Neonateswere healthy.Conclusion HIFU ablation is an effective mode for treating AM and can be used in the patients with AM and birth demand.

Objective To observe the delayed brain myelination of children with phenylketonuria(PKU)combined with epilepsia,and explore effectiveness of the treatment and provide an objective criteria for patient recovering evaluation.Methods There were 42 PKU patients,aged 3 to 72 months were selected.The concentration of phenylalanine tested by high pressure liquid chromatography was greater than 1.2 mmol/L in blood,diagnosed as PKU.According to electroencephalogram and clinical symptom,21 cases were diagnosed as epilepsy,the other 21 cases were used as control group.All patients were taken MRI before treatment.Myelination in 10 sections(cerebellum,pons,mesencephalon,internal capsule posterior limb,corpus callosum,internal capsule anterior limb,occipital lobe,parietal lobe,temporal lobe,frontal lobe)were evaluated.Results Delayed myelinations were located mainly in the cerebral lobes and corpus callosum,average delayed incidence of the 10 region was 44.8% in epilepsy group and 30.9% in control group.The incidence of the corpus callsum was 80.9% in epilepsy group,52.4% in control group,the number of sections of delayed myelination showed statistically significant between 2 groups(P

Objective To investigate the clinical effects of the modified Kock method of bladder re- construction with ileum,and to provide the objective basis for wide application of this technique.Methods A total of 51 patients with bladder cancer(T_2N_0M_0 stage tumor in 37 cases,T_3N_0M_0 stage tumor in 14; and pathologic gradeⅡ-Ⅲin all)were included.After radical cystectomy,modified Kock reconstruction of bladder with ileum was performed in them.The procedure consisted of preparing the segment of the ileum for reconstruction of the reservoir,anastomosing the low part of the neobladder with the urethra and regaining the original urinary conduit.Results The mean operative time was 6.5h(range,5.5-8.5h);mean in- traoperative blood loss was 650ml(range,300-1200ml),with blood transfusion in 31 cases.Perioperative complications included stress ulcer in 6 cases and urinary leakage in 1.The other 44 cases had no severe complications.Four cases died of cancer metastasis at 6-18 months after operation.During a follow-up of 8 -32 months,the other 47 cases recovered well and have been alive till now.Two cases had ureteral urine reflux with no impairment of renal function.The daytime urinary continent rate was 100%;and nocturnal uri- nary incontinence occurred in 6 cases.Conclusions The modified Koek reconstruction of bladder with il- eum can improve the patients'quality of life with fewer complications,therefore is a better treatment choice for infiltrative bladder cancer after radical eystectomy.

Objective To analyze the stability of chromosome variant ratio of three available transformed corneal cell lines. Methods Chromosome specimens of transformed cells including human corneal epithelial cells(HCE),bovine corneal endothelial cells(BCE) and rabbit corneal epithelial cells(RCE) were prepared by a direct method using regular Giemsa staining. Chromosomes of cells in metaphase were counted under the microscope. Then, the variant ratio of chromosomes and their nuclear types were analyzed. Results The chromosome numbers were 56 to 65, 27 to 34 and 74 to 88 for HCE, BCE and RCE, respectively. Chromosome numbers in the three commonly used and transformed corneal cell lines were changed in comparison to their parent tissues. Conclusion Genotyping study may provide important information for using HCE、BCE、RCE in functional studies.
