Objective To investigate the osteogenesis capability of different frequency extracorporeal shock wave.Methods 39 rabbits received different frequency extracorporeal shock wave at the middle potion of tibia for 3 or 7 days,these rabbits were then sac rificed and the tibia bones were collected to process for HE and toluidine blue staining,the pathological changes were observed under the light microscope.Results After different frequency extracorporeal shock wave treatment,the typical periosteal reaction were observed,external periosteum bleeded and thickened but there was no reaction at internal periosteum,marrow cavity opened and fibrosed.the osteoblast-1iking cell proliferated,however,no cartilage cells were observed;The rabbits received 7 days shock wave treatment showed more severe reaction than those for 3 days.The shock wave at lower frequency showed more severe reaction than higher frequency.Conclusion shock wave induced osteogenesis through the periosteal reaction of external periosteum;the osteogenesis capability of different frequency extracorporeal shock wave were affected by the frequency.Higher frequency of shock wave was not the ideal way to promote osteogenesis.

Objective To explore the effect and safety of transcranial approach for spheno-orhital meningioma. Design Retro- spective case series. Participants Thirty-two patients being operated with transcranial approach. Twenty-four cases were meningothelial meningiomas, 3 cases were fibrous meningiomas, 1 case was psammomatous meningioma, 2 cases were atypital meningiomas, 2 case were malignant meningiomas. Methods All patients underwent frontal-temporal craniotomy, the involved sphenoid wing bone and peri- orbit were removed to prevent recurrence. The superior orbital fissure and optic canal were decompressed, the dural and periorbital de- feet were repaired by autogenous temporal fascia or artificial dura. Main Outcome Measures Preoperative and postoperative exoph- thalmus and eyeball movement, the extent of tumor resection, the ratio of recurrence. Results The extent of tumor resection: 8 cases were Simpson gradeⅡ, 20 cases Simpson gradeⅢ, 4 cases Simpson grade IV. After surgery, proptosis were improved in all patients, ophthalmoplegia was found in 6 eases. There was no operation-related death or other significant complication. Tumor recurred in 6 cas- es. Conclusions Adequate exposure of the tumor and bony decompression of the cranial nerves can result from transcranial approach, all the involved bone should be removed in order to prevent recurrence. This approach is relatively safe and the ptoptosis are improved significantly. Complete surgical resection is difficult because of the involvement of the orbital apex, superior orbital fissure and cav- ernous sinus.

Thermo-therapeutic has been proved to be an effective approach for cancer therapy.This paper introduces a kind of new equipment suitable for liver oncology based on this theory,which uses the RF field as the thermal energy and adopts sequential-delivering technology.Its principle and advantages are introduced in detail.

Objective To investigate the levels of adiponectin and the relation with insulin and tumor necrosis factor(TNF)- ? in patients with cirrhosis. Methods Adiponectin,insulin and TNF-? levels were determined in 73 patients with cirrhosis and 30 healthy controls, and were correlated with various clinical and biochemical parameters. Meanwhile Child-Pugh liver function was classified. Results Adiponectin was significantly elevated in patients with cirrhosis compared with the control. Adiponectin levels in cirrhosis was correlated positively with insulin and negatively with insulin sensitively index,and did not correlate with TNF-? and liver function.Conclusion Serum adiponectin levels in cirrhosis are significantly elevated. Adiponectin levels do not correlate with TNF-? and liver function, but exclusively insulin and insulin sensitivity index.

Vitamin A is a fat-soluble vitamin, and it is not only necessary for the normal growth and development of epithelial cells, but also plays a very important role in the normal growth and development of the retina, lungs, gastrointestinal tract, brain, and immune system. Studies have confirmed that the low level of vitamin A in premature infants at birth can last through the entire infancy. Recently, there have been particular concerns about the level of vitamin A and development of diseases in premature infants, with major focuses on the related mechanisms of action of vitamin A in respiratory distress syndrome, chronic lung disease, retinopathy of prematurity, necrotizing enterocolitis, patent ductus arteriosus, and infections in premature infants, which still awaits further investigation.This paper summarizes and analyzes the current status of research on vitamin A level and diseases of premature infants at home and abroad. In addition, although enough evidence suggests that vitamin A supplementation is beneficial to preterm infants, evidence is still lacking for recommended methods for supplementation and dose of vitamin A, and further studies are needed.

Haploinsuffieiency of the runt-related transcription factor 2 (Runx2) gene is widely known to be responsible for cleidocranial dysplasia (CCD).To date,more than 190 mutations in Runx2 gene have been reported to be related to CCD.In this study,a novel mutation of Runx2 gene was observed in a female with CCD.Genomic DNA was extracted from peripheral venous blood of the proband and eleven members of her family.Genetic testing on these twelve people identified a novel missense mutation (c.895T＞C,Y299H) in exon 5 of the RUNX2 gene in the proband.This mutation results in an amino acid change at codon 895 (P.Tyr 299 His.) from a tryptophan codon (TAT) to a histidine codon (CAT).Our finding may further extend the known mutation spectrum of the RUNX2 gene,and facilitate prenatal genetic diagnosis of CCD in the future.

Objective To investigate drug resistance genes and epidemic characteristics of β-lactamase carried by carbapenem-resistant Acinetobacter baumannii (CRAB) in the respiratory intensive care unit(RICU) in a hospital.Methods Clinically isolated CRAB from RICU patients in October-December 2015 were collected.Five drug resistance genes (KPC-2,IMP,VIM,NDM-1,OXA-23) were specifically amplified by polymerase chain reaction (PCR),amplified products were performed agarose gel electrophoresis and sequencing analysis,the homology was analyzed with pulsed-field gel electrophoresis (PFGE).Results A total of 22 CRAB strains were isolated in October-December 2015,19 (86.36％) of which were isolated from sputum.The resistance rate of 22 CRAB strains to compound sulfamethoxazole was 59.09 ％,resistance rate to minocycline was 9.09 ％,all were sensitive to polymyxin B,resistance rates to other antimicrobial agents were more than 80％.Three kinds of resistance genes KPC-2,IMP and NDM-1 were not found by PCR amplification,positive rates of VIM and OXA-23 were both 100％.PFGE homology analysis revealed that 22 strains were divided into 13 different types,each type contained 1-5 strains,9 types(69.23％) contained only 1 strain respectively,the other 4 types (30.77％) contained 2-5 strains.A5,A7,and A8;A9,A11,A14,A19 and A22;A4,A10 and A12;A16 and A18 were of the same type respectively.Conclusion The main types of β-lactamase-resistant genes of CRAB in RICU are VIM and OXA-23.Homology analysis shows a small parts are of the same clone strains,which reveals epidemic of a small scale.
