2.Effect and safety of methylprednisolone pulse therapy on spinal nerve function in patients with acute spinal cord injury
Chinese Journal of Biochemical Pharmaceutics 2017;37(9):114-115,117
Objective To investigate the effect of methylprednisolone pulse therapy on spinal nerve functions in patients with acute spinal cord injury (ASCI) and evaluate its safety. Methods 200 patients with ASCI treated in our hospital from January 2010 to December 2016 were selected and were randomly divided into two groups,with 100 cases each group. The patients in control group were treated with routine basic treatment while patients in the study group were treated with methylprednisolone pulse therapy. On the basis of the American spinal cord injury Society scoring criteria (ASIA), the neurological functional recovery scores were performed were scored before and 6 weeks after treatment between the two groups and the adverse reactions were recorded. Results The scores of sensory and motor function of the patients in the two groups were higher than those before the treatment and there was statistical difference (P<0.05), and the scores in the study group was significantly higher than those in the control group, and the difference between the two grouPs was statistically significant (P<0.05). The incidence of adverse reactions in the study group (25.00%) was significantly higher than that in the control group (10.00%), and the difference was statistically significant (P<0.05). The incidence of lung infection and gastrointestinal reaction in the study group were significantly higher than those in the control group and there were statistical difference (P<0.05). Conclusion Methylprednisolone pulse therapy has significant effect on the recovery of neurological function in patients with ASCI, but the incidence of adverse reactions is high, so it is necessary to strengthen the monitoring and intervention in clinic.

4.Research progress in topical application of anti-vascular endothelial growth factor drugs for uveitis-associated cystoid macular edema and choroidal neovascularization
Chinese Journal of Experimental Ophthalmology 2014;32(7):659-663
Uveitis is a kind of inflammatory disease affected in ocular posterior segment.Uveitis sustains a long duration and causes a significant damage of visual function.It often leads to serious complications,such as cystoid macular edema (CME),cataract,glaucoma,retinal detachment and choroidal neovascularization (CNV).In the pathological process of uveitis,inflammatory factors promote the release of vascular endothelial growth factor (VEGF) through a variety of pathways.It has been verified that VEGF level is elevated in vitreous in the patients with uveiticinduced CME.Intravitreal injection of anti-VEGF drugs,including ranibizumab and bevacizumab,can improve the visual acuity in most patients with noninfectious uveitic-induced CME and CNV.However,intravitreously repeated injections of anti-VEGF drugs may be required in some patients.Intraocular injection of anti-VEGF drugs is an optional and effective way for those with persist macular edema and not being suitable for the use of corticosteroid or immunosuppressive therapy.However,anti-VEGF drugs may affect the efficacy of corticosteroid.Therefore,more clinical and basic researches are still needed.The status and progresses in the use of anti-VEGF drugs for uveitisinduced CME and CNV were reviewed.
5.Design and manufacture of a novel orientation device of elbow rotation center
Chinese Journal of Orthopaedic Trauma 2016;18(7):616-620
Objective To report the design and manufacture of a novel orientation device of elbow rotation center.Methods The anatomical data of distal humeral elbow were obtained from 3 reports on the anatomy of the distal humerus retrieved from CNKI from 2004 through 2014.Software UGS.0 NX,CAD/CAM animation and video were used to design the 3D model of our novel orientation device of elbow rotation center.The glass fiber physical model of the device was manufactured using 3D printing technology.Five healthy volunteers were recruited for a simulated surgery experiment to test the efficacy and accuracy of the device,including 4 males and 1 female,from 25 to 36 years of age.Results No change was observed before and after the device was disinfected regarding the length (129 mm),width (116 mm) or height (215 mm),or other shapes.Satisfactory X-ray images of the elbow were obtained in the 5 volunteers.The fluoroscopy frequency required ranged from 6 to 11 times,averaging 8.2 times.The time needed for orientation ranged from 442.2 to 554 seconds,averaging 489.2 seconds.Conclusions Our self-designed orientation device can be used to accurately position and orientate the rotation center of elbow joint,showing its reasonable design.Glass fiber materials can be used to manufacture our orientation device.
6.Titanium versus polymethyl methacrylate resin complete denture base A phonology evaluation
Chinese Journal of Tissue Engineering Research 2010;14(42):7976-7980
BACKGROUND: Several studies have demonstrated that the range,thickness and morphology of oral prosthesis directly influence patient's phonetic function,and titanium base and polymethyl methacrylate(PMMA)resin base yield different influences on phonetic function due to different thicknesses of materials.OBJECTIVE: To analyze the phonetic parameters in one complete denture patient who wear titanium base and PMMA resin base simultaneously and investigate the influences of maxillary complete denture base on phonetic function.METHODS: Through the use of computer-based voice analysis software PRAAT4.4.34,frequency value of the first concentrated frequency area when speaking consonant sounds/x,sh,r,zh,ch,j,q/and voice onset time when speaking consonant sounds/g,k,zh,ch,j,q/were statistically analyzed in the same patient who separately wear titanium complete denture base and PPMA resin complete denture base,and spectrogram of velar stops between complete denture bases was compared.RESULTS AND CONCLUSION: MMPA resin complete denture base was to some extent poor in promoting the recovery of phonetic function owing to great base thickness.Titanium complete denture base with less thickness in the tongue or palate region would help recovery of phonetic function.Extraction and analysis of phonological parameters,such as frequency value of first concentrated frequency area and voice onset time,using CSL computer*based voice analysis system,would provide objective evidence for lamprophony analysis after wearing complete denture.Maxillary denture with thinner base in tongue and palate regions better promotes the recovery of patient's phonetic function.

Objective To observe the protective effect of Ulinastatin in rat islet isolation and advance an improved method in rat pancreas islet isolation.Methods Rat pancreas was perfused with Hanks solution containing collagenase. The rats were divided into 3 group according the Ulinastatin concentrations in collagense: low-concentration Ulinastatin ( 2500 U/ml) group, high-concentration Ulinastatin ( 5000 U/ml) and control group (no Ulinastatin). The isolated pancreases were compared among the groups. Results The shape and number of the isolated pancreases in low-concentration Ulinastatin and high-concentration Ulinastatin groups were superior to those in control group (P

Objective The aim of our study was to evaluate the efficacy and safety of tirofiban in patients with acute coronary syndromes with thrombus-containing lesions.Methods We randomized 38 acute coronary syndromes(ACS)patients with thrombus-containing lesions into tirofiban group and control group.In the tirofiban group,10~30 mL of tirofiban was administered intracoronar before and/or after percutanous transluminal coronary angioplasty(PTCA),then stent was implanted as needed.Intravenous tirofiban was used for 24~48 hours after the procedure.In the control group,standard percutanous coronary intervention(PCI)was used for the patients.TIMI thrombosis grade,TIMI blood flow,no reflow and/or slow flow,corrected TIMI frame count(cTFC),myocardial blush grade(MBG),left ventricular eject fraction(LVEF)were measured in the two-dimensions untrasonography;major adverse cardiac events(MACE)and bleeding were observed.Results TIMI thrombosis grade and cTFC decreased more in the tirofiban group than that of the control group[0.90?0.14 vs 1.53?0.54,P
