After completing the producing of the televised teaching material of TCM Bone-setting Skills,which was sponsored by Scientific and Teaching Section of Ministry of Health,and applying it to the teaching process in classroom for undergraduate students in Southern Medical University,The students were asked to fill out a questionnaire so as to preliminarily explore the applying methods and assess its teaching value under the circumstances of multimedia teaching.

This paper discussed the differences in teaching arrangement,material construction,teaching pattern, and teaching methods been used in medical microbiology teaching between China and the United State.

Objective To evaluate the effect of different education models on the self care ability of peripherally inserted central catheters (PICC) placement patients.Methods The randomized controlled trial (RCT),controlled clinical trail (CCT),self-controlled trial and cohort study on self care ability of patients with PICC placement were collected using databases by manual and Internet searching.Data were analyzed with Revman5.0 software,data which could not be gathered were expressed by descriptive analysis.Results Eight articles were included in the study.The results of Meta-analysis revealed that different education models could significantly improve the self care ability of PICC patients in the intervention (experimental) group.Conclusions Different education models had significant meaning on the self care ability of PICC placement patients.

Background The characteristics of anisometropic amblyopia in ocular morphology are becoming a hot topic in amblyopia field.And the interocular difference in corneal parameters of anisometropic amblyopia is to be understood here.Corneal topography is a non-invasive method for in vivo corneal examination and applied in our study.Objective This study was to investigate the interocular difference of corneal topography in anisometropic amblyopic patients Methods This was a serial cases observation.Thirty anisometropic amblyopes were selected in Center for Optometry and Visual Science,People's Hospital of Guangxi Zhuang Autonomous Region.The patients were divided into amblyopic eye group and fellow eye group based on the best corrected distance visual acuity.Corneal topography was examined with Orbscan Ⅱ z,and corneal morphological parameters such as Diff values of the anterior and posterior corneal surface,Sim K 's astigmatism,Kmax,angle kappa and central corneal thickness (CCT) were measured.The interocular differences in these parameters were evaluated by paired t test,and the correlations in these parameters between the amblyopic eyes and the fellow eyes were analyzed by Pearson linear correlation and simple regression analysis.Results The Diff values of the anterior corneal surface were (0.011±0.006)mm and (0.011±0.017)mm,and those in the posterior corneal surface were (0.031 ±0.012)mm and (0.026 ±0.008)mm in the amblyopic eye group and the fellow eye group,respectively.In addition,Sim K's astigmatism were (1.8± 1.1)D and (1.1 ±0.6) D,JCC were (77±80) °and (100±80) °,J0 values were (-0.17±0.72) D and (0.02±0.41) D,J45 values were (-0.16±0.79) D and (0.13 ±0.48) D,CCT values were (551 ±37) μm and (551 ±31) μm,angle kappa values were (6.4± 1.4) ° and (4.9 ± 1.2) ° in the amblyopic eye group and the fellow eye group,respectively.Significant differences were found in the Diff values of the anterior and posterior corneal surface,Sim K's astigmatism and angle kappa between the two groups (t=-3.041,P=0.005 ;t=-4.317,P=0.000 ;t=-4.571,P=0.000).Pearson's linear correlation test demonstrated significant interocular positive correlations in parameters such as the anterior corneal surface Diff values (r =0.444),J0 (r =0.383),posterior Diff values (r =0.600),and Sim K 's astigmatism (r =0.479),and CCT (r =0.948,P＜0.05).The linear regression equation between the two groups was Y =-0.005 +1.392X (R2 =0.197,F=6.858,P=0.014) in the Diff values in the anterior corneal surface,Y =-0.013+0.421X (R2=0.360,F=15.761,P=0.000) in the Diff values in the posterior corneal surface,Y =0.616+0.27X (R2=0.230,F=8.348,P=0.007) in the Sim K's astigmatism,Y=0.060+0.219X (R2 =0.147,F=4.814,P=0.037) in theJo and Y=i08.289+0.804X (R2 =0.899,F=250.293,P=0.000) in CCT.Conclusions Corneal morphological interocular differences exist significantly in anisometropic amblyopic patients.

BACKGROUND:The poly(hydroxybutyrate-co-hydroxyoctanoate) osteochondral scaffold which has been constructed in previous experiments has good biocompatibility and biodegradability and generates non-toxic degradation products.
OBJECTIVE:To observe the vascularization of rabbit renal microvascular endothelial cels co-cultured with poly(hydroxybutyrate-co-hydroxyoctanoate) osteochondral scaffold.
METHODS:The poly(hydroxybutyrate-co-hydroxyoctanoate) osteochondral scaffold having a three-layer structure (layer of bone/bone and cartilage interface layer/layer of cartilage) was prepared by solvent casting/particle leaching method. The renal microvascular endothelial cels at passage 3 were seeded onto the scaffold of bone layer. The proliferation of the renal microvascular endothelial cels growing on the scaffolds was examined using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide method, the growth of cels in the scaffold was observed by hematoxylin-eosin staining under electron microscope after 10 days.
RESULTS AND CONCLUSION:The integrated osteochondral scaffold had a clear appearance of three-layer structure, which had closed connections between the three layers. Porous bone layer was visible as wel as uniform and interlinked pores, and the porosity was 78%. The renal microvascular endothelial cels seeded onto the scaffold proliferated wel and presented a three-dimensional growth after 10 days of co-culture, but there were no cels on the interface layer. Cels which adhered and grew between the pores of the bone layer were observed through hematoxylin-eosin staining. Cels showed a luminal-like structure growing on the scaffold with the porous structure, but they did not grow into the interface layer of bone and cartilage.

For the high cost and mobility issues, a home uterine contraction pressure monitoring system based on Windows CE platform was developed. In this paper, the design of hardware circuit, micro-controller system and LabVIEW program based on Windows CE are discussed. The clinical validation experiment in hospital for this system was made and the experimental results show that this system complies with the trend that current medical equipment is becoming portable, homely and networked. Through real-time monitoring uterine contraction pressure, occurrence of premature birth and abortion can be prevented effectively.

OBJECTIVETo explore the clinical effects of internal fixation with lag screws plus an anti-sliding plate for the treatment of Hoffa fractures of the lateral femoral condyle.

METHODSFrom May 2006 to May 2014, 17 patients with Hoffa fractures of the lateral femoral condyle were treated with lag screws plus an anti-sliding plate. There were 13 males and 4 females, ranging in age from 27 to 59 years, with a mean of 32.5 years. All the fractures were fresh and closed fractures. According to the Letenneur's classification, 8 cases were type I, 4 cases were type II, 5 cases were type III. All the patients had no injuries of the cruciate ligament and the another part of the knee. Operative incision and fracture healing time were observed, knee joint function was evaluated by Letenneur system and HSS standard.

RESULTSThe patients were followed up from 10 to 24 months with a mean of 14.6 months. All incisions achieved primary healing, and no internal fixation breakage, malunion, femoral candyle necrosis, deep vein thrombosis of lower extremity were found. Fracture healing time was from 4 to 9 months with an average of 4.7 months. According to Letenneur's functional assessment, 10 patients got an excellent results, 4 good, 3 fair. Total HSS score was 91.1 +/- 4.7 on average,15 cases obtained excellent results, 2 good.

CONCLUSIONInternal fixation with lag screws and an anti-sliding plate can result in excellent effects for Hoffa fractures of the lateral femoral condyle. The key to a successful surgery is an anatomic reduction and rigid fixation of the fracture.
