Objective To evaluate the efficacy of prevention of recurrent femur fracture in children with osteogenesis imperfecta.Methods Data of 35 patients (19 boys,16 girls) who were treated for femur deformity due to osteogenesis imperfecta at our hospital from Jun 2009 to Jun 2013 were retrospectively analyzed.The average age of the patients was 9 years 3 months,ranging from 3 years 6 months to 13 years 1 month.All the patients had suffered from recurrent femur fractures before which led to femoral deformity.The mean angulation angle was 55° (range,10°-90°).10 patients were operated at one side;the other 25 patients were treated bilaterally.None of them received operation before for fractures.The average incidence of femur fracture before operation was 2.4/year (range,2-4).According to the modified Sillence classification system,9 were type Ⅲ OI,14 type Ⅳ,and 12 type I.The curved deformity of the femurs were corrected by osteotomy and stabilized by telescopic intramedullary rods in 35 patients.Results All the 35 patients were followed up for a mean period of 62 months (range,36-72).The average healing time of the osteotomy site of the femur was 8.5 weeks (range,7-12).The patient was encouraged to begin weightbearing and walking when the Xray film showed healing of the osteotomy site.By the latest follow up,80％ of the patients could stand and walk independently.The incidence of femur fracture decreased significantly to the level of 0.3±0.1/year,compared with the level of 2.4± 1.3/year before operation.All the parents of the children were satisfied with the result of deformity correction.At the latest follow up,the Barthel index score increased from 71.82 (range,51-92) before operation to 92.32 (range,82-100) postoperatively,while the WeeFIM score increased from 53.32 (range,42-72) before operation to 78 (range,70-86) postoperatively.The difference of Barthel index score and WeeFIM score between that before and post operation was significant.The children's selfcare and motion ability improved obviously after operation.During follow up,22 patients suffered from recurrent fracture of the femur by various degree,7 of them were treated by open reduction and telescopic rodding surgery,while the other 15 patients were treated conservatively because the fracture displaced or angulated minimally and the fracture healed uneventfully.Conclusion The telescopic intramedullary rod can maintain the correction of the femur deformity and improve the quality of the bone,thus prevent the recurrent fracture of the femur in children with osteogenesis imperfecta effectively.

Objective:To investigate the changes of macular region structure before and after operation in patients with macular epiretinal membrane,and its relationship with the visual function of patients.Methods:The clinical data of 60 patients with macular epiretinal membrane (60 eyes) in our hospital from February 2014 to August 2016 were retrospectively analyzed.All patients were examined with optical coherence tomography (OCT) examination,and observed the changes ofmacula central fovea and retinal each azimuth thickness,and the best corrected visual acuity (BCVA) was recorded before and after operation,and the correlations of them were analysised.Results:The visual acuity was improved in 53 patients (53 eyes) after operation,accounting for 88.33％,and the visual acuity was unchanged in 7 patients (7 eyes),accounting for 11.67％.The preoperative BCVA of patients was (0.18± 0.07),and it was (0.38± 0.12) at 3 months after operation,which was significantly higher than before operation (P＜0.05).Postoperative macular central thickness,inner side of the inner ring thickness,nasal side of the inner ring thickness,above the inner ring thickness,below the inner ring thickness,outer ringtemporal side thickness,external ring nasal side thickness,above the outer ring thickness,below the outer ring thickness in patients compared with the preoperative were significantly lower,the difference was statistically significant (P＜0.05).The Pearson correlation analysis showed that preoperative macular central thickness,preoperative inner side of the inner ring thickness,preoperative outer ring temporal side thickness,the difference of macular fovea thickness before and after operation,the difference of the medial temporal before and after operationwas,the difference of outer ring temporal side before and after operation were negatively correlated with postoperative BCVA (P＜0.05).Conclusion:Vitrectomy can significantly reduce macular retinal thickness in patients with macular epiretinal membrane,and it can improve the visual function of patients,and the shape ofmacular region before operation had some influence on postoperative visual acuity.

A 43-year-old man was diagnosed as massive left occipital lobe hemorrhage with the hematoma expanded into the entire ventricular system. On admission, he was in deep coma with clinical signs of brain herniation and a Glasgow Coma Scale (GCS) score of 4. Vascular malformations were highly suspected since he was young with no history of hypertension. Considering the life-threatening situation, open craniotomy and hematoma evacuation was proposed as the first therapeutic option, but this was refused by his family members for non-medical reasons. In order to save his life, stereotactic aspiration was suggested again and was accepted. UK at an aggressive dosage of 50 000 IU was administered during and after the surgical procedure for 5 days. One month later, this patient gained an excellent recovery with a Glasgow Outcome Scale (GOS) score of 5.

A low calcium medium developed for epidermal keratinocytes were prepared according to the MCDB 153 modified formula and used in human epidermal keratinocyte culture compared with DMEM culture system. The observation by contrast microscopy and electron microscopy showed that in the low calcium medium keratinocytes grew as a monolayer of high proliferation and had many characteristics of basal cells, with a more rounded shape and large intercellular spaces. Increasing the calcium ion concentration in the medium or changing the other culture conditions the cells in these cultures could be induced stratification and terminal differentiation. The results suggest that the growth, proliferation and differentiation of cultured human epidermal keratinocytes can be controlled and regulated someway.

Objective To establish the proper review rules for the microscopic screening of urine analyzed by UF-1000i automatic urinalysis work station (composed of UF-1000i urine flow cytometer and AX-4030 urine dry chemical analyzer).Methods A total of 2 839 random urine samples were collected at Chinese People′s Liberation Army General Hospital from September 2009 to February 2010, and were analyzed using UF-1000i urinalysis work station.The parameters obtained from UF-1000i and AX-4030 included RBC, WBC, CAST and ERY, LEU, PRO.After analysis by urinalysis work station, each urine sample was examined microscopically by two technologists using double-blind method.The average results got from the two technologists were regarded as the judging criterion.Based on the criterion, the review rules for the 2 839 urine samples tested by urinalysis work station were created and adjusted, and the true positive rate, false positive rate, true negative rate, false negative rate and review rate of these review rules were calculated.After that, 299 randomly selected urine samples were tested to validate these review rules.Omission diagnostic rate and review rate were used to assess the clinical practicability of the review rules.Results Thirty seven rules for microscopic review and twenty seven rules without further microscopic examination were set up based on six parameters using UriAccess 3.0 Software.The microscopic examination result was taken as the judging criterion, the consistency rate of these rules was 81.11%(2 311/2 839), the true positive rate was 40.51%(1 150/2 839), the false positive rate was 16.17%(459/2 839), the true negative rate was 41.00%(1 164/2 839), the false negative rate(omission diagnostic rate) was 2.43%(69/2 839) and the review rate was 18.28% (519/2 839).Additional 299 urine samples were assayed using UriAccess3.0 software to further verify these review rules.The consistency rate was 82.27%(246/299), the true positive rate was 36.12%(108/299), the false positive rate was 16.39%(49/299), the true negative rate was 46.15%(138/299), the false negative rate(omission diagnostic rate) was 1.34%(4/299), the review rate was 19.06%(57/299). The 4 false negative samples selected by these review rules did not come from the nephropathy department or the urology department.Microscopic results of RBC and WBC form these 4 samples ranged 3-8 cells/HP. Thus, these review rules could avoid the missed diagnosis of those patients with severe renal dysfunction.Conclusion The review rules established from this study for the UF-1000i urinalysis work station can effectively detect abnormal urine samples and improve the efficiency and the quality of urinalysis in routine clinical practice.

OBJECTIVE: To investigate the in vivo possibility of osteogenesis and angiogenesis of tissue-engineered periosteum in rabbits.METHODS: The marrow mesenchymal stem cells (MSCs) derived from New Zealand rabbits were adhered to small intestinal submucosa (SIS) to fabricate the tissue-engineered periosteum. Totally 12 New Zealand rabbits were received critical bone defect in bilateral radii to prepare models. The tissue-engineered periosteum was randomly implanted in one side of bone defect,and the other side was treated by SIS. At 4 weeks after operation, the angiogenesis of tissue engineered bone was detected by Tetracycline fluorescence microscopy and formaldehyde-ink perfusion method; simultaneously, the new bone formation was firmed by haematoxylin-eosin staining.RESULTS: Animals showed normal daily behaviors and non-infection wounds healing. The gross observation showed that bone defects in the experimental side were bridged with newly formed bone; while the defects of the control side were remained empty.Tetracycline fluorescence microscopy and hisotological examination could confirm the new bone tissue formation in the experimental side. The ink staining in new bone specimens suggested that there were abundant of neovasculization in tissue-engineered bone.CONCLUSION: Tissue-engineered periosteum can form new bone in allogenic rabbits and can be vascularized by some inherent mechanism for new bone tissue survivor.

Objective To evaluate specific clinical and imaging features of osteogenesis imperfecta V and to improve diagnostic accuracy of this disease. Methods Data of 15 patients with osteogenesis imperfecta type V were retrospectively analyzed for their clinical and imaging features. There were 10 males and 5 females, aged from 1 year and 30 years old (median age,12.5 years ). All 15 patients had plain X-ray, and 4 of 15 had CT. All data were analyzed by 3 experienced deputy chief doctors in OI according to OI V standard. Results X-ray:calcification of the interosseous membrane between radius-ulna was detected in all patients and calcification of the interosseous membrane between tibia-fibula was detected in 2 of 15 patients. Dislocation of the radial head was seen in 13 of 15 patients,bilateral in 9 and utilateral in 4.All patients showed restriction in the pronation and supination of the forearm and restricton in the flexion and extention of the elbow joint. Patients with dislocation of raidal head were associated with large coronoid process and olecranon of the ulna. Hyperplastic callus of the extremities were detected in 7 of 15 patients (7 at femur , 3 at humerus, 1 at tibia.In early stage, hyperplastic callus showed thin cortice, and clear boundares with the diaphysis showing and low density, irregular, mesh-like lamellation inside. In the later stage, there were dense calcification inside hyperplastic callus, and no difference in density with the diaphysis. Diaphysis surrounded by hyperplastic callus had clear boundaries with the hyperplastic callus. No cortical destruction was detected. CT:there were sparse needle-dot calcification inside hyperplastic callus, with the patterns of granular, ring-and-arch,irregular streaky mineralization. The cross section of proximal femoral shaft showed irregular shape , flat square shape and tiny medullary cavity, with no calcification on the edge of hyperplastic callus. CT value:-91 HU inside hyperplastic callus; 283 HU in femoral shaft. Conclusions Interosseous membrane between radius-ulna or tibia-fibula, hyperplastic callus ,dislocation of the radial head are specific features in osteogenesis imperfecta V. X-ray can make a definitive diagnosis of osteogenesis imperfecta V. CT scan is helpful in the differential diagnosis of osteogenesis imperfecta V from osteosarcoma.

BACKGROUND:Ideal osteochondral tissue-engineered scaffolds should be able to mimic the normal structure ofhuman articular cartilage. OBJECTIVE:To prepare a layered osteochondral composite scaffold based on the anatomical and physiological functions of osteochondral articular cartilage and to observe its repair effect on osteochondral defects in rabbits. METHODS:The poly (lactide-glycolide acid)/β-tricalcium phosphate organic solution was sprayed on the surface of cartilage scaffold using rapid prototyping technology. The layered osteochondral composite scaffold was formed by the“dissolving-adhesion”process. Sixty rabbits were enrol ed, modeled into left knee articular cartilage defects, and then randomly divided into three groups. The layered osteochondral composite scaffold and cartilage scaffold were implanted into experimental and control groups, respectively. Those without any treatment served as controls. Gross and histological observations of the defect region were performed at 12 and 24 weeks after implantation. RESULTS AND CONCLUSION:Gross observation:At 12 weeks after implantation, the defects in the control group were obvious and not repaired at al;the 24-week defect area was decreased, covered by newly formed tissues, but with rough surface. In the experimental group, the defect surface was flat after 12 weeks of implantation, the texture was soft, and the boundary with the surrounding tissues was unclear;at 24 weeks, the defect was covered with transparent cartilaginous tissues and the surface was smooth. Histological observation:At 12 weeks after implantation, the irregular cal us appeared in the control group, but the trabeculae were not formed;in the experimental group, the thickness of the new cartilage was similar with that of the normal cartilage and there was irregular trabecular bone under the cartilage. After 24 weeks of implantation, there were new tissues in the control group, but the thickness was irregular and uneven and the trabecular structure was irregular;while the cartilage surface was smooth and repaired wel in the experimental group. In contrast, repair effect in the control group was poor as assessed by gross and histological observations. These results show that the layered composite scaffold holds a similar structure with human articular cartilage and can promote the repair of articular cartilage defects.

Objective To investigate the effect of macrophage polarization on tubulointerstitial fibrosis of mouse unilateral ureteral obstruction(UUO) model.Methods Twelve male C57BL/6J mice were employed,each of which with an age of 8 to 10 weeks.UUO model was established with these mice with the method of unilateral ureteral ligation.Mice were then sacrificed on the 7th and 14th day respectively after operation,and renal tissue specimens were obtained.The authors detected collagen deposition by Masson staining,and alpha smooth muscle actin (alpha SMA) as well as collagen type Ⅰ (Coll-1) mRNA by real-time quantitative PCR.The authors also detected the degree of renal interstitial macrophages infiltration and expression changes of polarization by immunofluorescence staining.Results Compared with the mice that were observed on the 7th day after operation,the degree of renal interstitial fibrosis in mice observed on the 14th day after operation was comparatively serious,the difference shown by semi-quantitative results was statistically significant (P ＜ 0.05).Moreover,mice observed on the 14th day after operation have more M2 macrophages,the difference between two groups of mice was statistically significant (P ＜ 0.05).On the contrary,there was no statistically significant difference in the degree of M1 macrophages infiltration between these two groups of mice.Conclusions In the renal interstitial fibrosis model induced by UUO,the degree of macrophage infiltration increased significantly,mainly resulted from M2 macrophage infiltration,suggesting that M2 macrophages were involved in the formation of renal fibrosis.
