BACKGROUND:Most orthopedic surgeries use metal implants. Although this approach wil benefit for patients, it simultaneously makes patients infected by some bacteria. Serum C-reactive protein level and erythrocyte sedimentation rate are two indices for clinical y determining the inflammation. OBJECTIVE:To investigate the changes in serum C-reactive protein level and erythrocyte sedimentation rate in patients after use of orthopedic metal implants. METHODS:The clinical data of 100 patients who used metal implants between October 2012 and October 2014 at the Department of Orthopedics, Linqu People’s Hospital of Shandong Province of China were retrospectively analyzed. Among these patients, 36 patients received implantation of intramedul ary nails, 34 patients artificial joint, and 30 patients steel plates. At 1, 3, 7, 14, and 21 days after implantation, infection was determined according to serum C-reactive protein level and erythrocyte sedimentation rate, as wel as other laboratory indices, wound healing, and body temperature. According to these indices, the patients were assigned to two groups:no infection (n=52) and infection (n=48). Disease progression was analyzed for providing reliable evidence for rational use of antibiotics. RESULTS AND CONCLUSION:There were significant differences in serum C-reactive protein level and erythrocyte sedimentation rate in patients between infection and non-infection groups at 1 (t=3.43, P<0.05;t=3.78, P<0.05), 3 (t=3.35, P<0.05;t=3.68, P<0.05), 7 (t=3.28, P<0.05;t=3.54, P<0.05), and 14 days after use of orthopedic metal implants (t=2.56, P<0.05;t=3.02, P<0.05). No significant differences in these two indices were observed between infection and non-infection groups at 21 days after use of orthopedic metal implants (t=1.76, P>0.05;t=1.98, P>0.05). These findings suggest that after use of orthopedic metal implants, serum C-reactive protein level and erythrocyte sedimentation rate in patients should be closely monitored and simultaneously other indices like wound healing and body temperature should be determined to determine whether infection occurs after use of orthopedic metal implants so as to develop effective repair strategies. This wil provide reliable clinical evidence for rational treatment and prevention of orthopedics-related diseases.

Objective To establish the rat ischemia-reperfusion injury model and learn the rat apoptosis changes after ischemia-reperfusion injury.Methods Ligate rat left common carotid artery 1h,reperfuse and exam retinal apoptosis in 1,6,12,24,48 and 72h groups.Result Apoptosis mainly occurs in retina ganglion cell layer and inner nuclear layer,occasionally in outer nuclear layer.Apoptosis occurs in 6h after reperfusion.In 24h,apoptosis achieves the peak,then decrease gradually.However,in 72h after reperfusion,there is apoptosis in rat retina.Conclusion rat retina ischemia-reperfusion injury can be observed after ligating common carotid artery.Apoptosis may play an important role in rat retina ischemia-reperfusion injury.In 72h after the operation,the injured retina didn't recover completely.

Objective To evaluate the efficacy and safety of dexmedetomidine combined with propofol for gastroscopy in elderly patients.Methods Ninety ASA physical status Ⅰ-Ⅲ patients,aged 65-80 yr,weighing 45-80 kg,scheduled for elective gastroscopy,were randomized to receive either dexmedetomidine combined with propofol (group DP,n =45) or propofol (group P,n =45).In group DP,dexmedetomidine 0.4 μg/kg was infused over 5 min and propofol 1.0 mg/kg was injected intravenously 25 min later.Propofol 2.0 mg/kg was injected intravenously in group P.When body movement occurred during operation,additional propofol 0.2 mg/kg was given intermittently.Mean arterial pressure (MAP),heart rate (HR),pulse oxygen saturation (SpO2) and Narcotrend index were monitored during the whole procedures.The consumption of propofol and vasoactive agents,adverse cardiovascular events,and respiratory depression were recorded.Results Compared with group P,the consumption of propofol,incidences of respiratory depression and tachycardia,and degree of body movement were significantly decreased (P ＜ 0.05),Narcotrend index was increased during operation (P ＜ 0.01),and no significant change in the incidence of circulatory depression was found in group DP (P ＞ 0.05).Conclusion Small dose of dexmedetomidine 0.4 μg/kg combined with small dose of propofol 1.0 mg/kg provides good efficacy and safety for gastroscopy in elderly patients.

Objective To evaluate the efficacy of ECP and glaucoma drainage device implant in the management of refractory glaucoma. Methods A retrospective study was explored in refractory glaucoma in 99 eyes,in which there were 50 eyes in the ECP group(group A)and 49 eyes in the group of glaucoma drainage device implant (group B). The changes of intraocular pressure (IOP),visual acuity and complication were observed. Results (1)IOP:There was statistically significant difference in IOP between the preoperative and last follow-up in each group(T-Test,t = 2.47,t = 2.51,P < 0.05),and statistically significant difference in IOP between the two groups in the rest of time points of postoperation except the 2 and 7 days after operation.(2)BCVA:T The visual acuity was no statistically significant difference between the two groups(χ2-Test,χ2 = 37.85,P >0.05).(3)Complication:The early complications of the group A included anterior chamber exudation ,short-term high IOP,hyphema. In the group B,the early complications included shallow anterior chamber,hyphema, drainage valve block and high IOP,MSCH,choroidal detachment,while the medium-term complication was glaucoma valve fiber wrapped high IOP and the long-term complications included glaucoma drainage tube rejection , exposure and displacement,and endophthalmitis,conjunctival hyperplasia. Conclusion ECP and glaucoma drainage implant can be effective in the treatment of refractory glaucoma. The ECP has less complications.

Objective To explore the application of combined penile and scrotum skin flap in the reoperation process for operation failure cases with hypospadias.Methods A retrospective analysis was performed with the inclu-sion of 1 5 failure cases with hypospadias who received combined penile and scrotal skin flap treatment for reoperation from January 201 3 to December 201 5 in the First Affiliated Hospital of Guangxi Medical University.These cases aged from 7 to 1 5 years old,with a median age of 1 0.2 years old.Among them,a 3 rd operation was performed in 4 cases,4th operation in 5 cases,5 th operation in 4 cases,and 6 th operation in 2 cases.The procedure of Onlay island flap urethro-plasty +tubularized incised plate (Onlay +TIP)urethroplasty was performed in 4 patients,and the other 1 1 cases were treated with urethral mouth basal vascular skin tube urethroplasty (Mathieu)+TIP urethroplasty.F8 or F1 0 silicone balloon catheter were used as stent in new urethra,outer dressing after operation was replaced every 2 to 3 d,the outer dressing was demolished 6 -8 d after operation.Results All patients were followed up after surgery until March 20, 201 6,the follow -up time was 4 -26 months.In these 1 5 patients,the success rate of operation was 86.7%(1 3 /1 5 ca-ses),among them,3 cases were success and 1 case was failed in Onlay +TIP group,and 1 0 cases were success and 1 case was failed in Mathieu +TIP group.The patients with successful operation were with beautiful appearance of the pe-nis,normal position of the meatus urinarius and normal urination.No peristome of urethra,urethrovaginal fistula or ure-thral diverticulum was found after surgery.However,urethral cracking of the glans of penis appeared in 2 operation failed patients,and the orificium urethrae externum was low -set,and urethroplasty was needed 1 year postoperatively. Conclusions For some failure cases with hypospadias showing suitable anatomy conditions,Onlay +TIP or Mathieu +TIP combined with penile and scrotal flap may be a good choice for the completion of reoperation.

[Objective]To investigate the operation indications and techniques of the ISOLA spinal system in reconstruction of the lumber-pelvis continuity after resection of high-level sacral tumors. [Method]A retrospective study was performed in 43 patients with high-level sacral tumor (HLST) between July 2001 to January 2007. Symptoms, signs, histological findings of the tumors and their outcomes were analyzed. All patients underwent resection of HLST and spinopelvic reconstruction with ISOLA spinal system,11 unilateral and 32 bilateral.[Result]Among the 43 patients, 33(77.1%)had chordoma, giant cell tumor of bone and neurogenic tumors. Thirty-four patients alive were followed-up for an average of 35 months(12~62 months), 5 patients had a recurrence of chordoma and 29 patients with HLST were under control. The pain originated from the lumbosacral joint and the spinal nerve root was obviously relieved.The patients could stand and ambulate normally. No loose screw or broken rod were found.X-rays showed no signs of the enlarged screw canal or lowered lumbar spine.The effect was 76.5%(26/34) excellent judged by the ISOLS system.[Conclusion]Spinopelvic reconstruction by ISOLA system after resection of HLST is characterized by easy manipulation, less complications and instant stable fixation. It may be widely used in the clinical practice.

Resistance to adriamycin was developed in an orignally adriamycin- sensitive strain of Ehrlich ascites carcinoma (EAC) in vivo by treament with the adriamycin during 50 weekly passages of the tumor. The results showed that the growth of the resistant line was slower than that of the EAC, total ascites cell volume,total cell number and mean single-cell volume were significantly smaller of the resistant line than those of original sensitive line. Also, itwas found the homogerously staining region and double minute chromosome in the cells of resistant line. The adriamycin-resistant tumor produced cross resistance to vincristine.mitomycin C,and actinomycin D,while section resistance to VP-16. There was no change in the sensitivity of tumor to oridonin.
