AlM:To study and investigate the change situation of trace elements and body comprehensive immune state of patients with viral keratitis.METHODS:Sixty-two patients with viral keratitis in our hospital from December 2011 to February 2014 were selected as observation group, 62 healthy persons with health education at the same time were the control group, then the serum and tear Zn, Cu, cellular immunity and erythrocyte immunity of two groups were compared, and the detection results of observation group with different types and severity degree were compared.RESULTS:The serum and tear Zn of observation group was all lower than that in control group, serum and tear Cu was higher than that in control group, cellular immunity and erythrocyte immunity indexes were all worse than that in control group, the detection results of observation group with mild, moderate and severe infection had significant differences (P<0. 05), while the detection results of observation group with herpes simplex keratitis and herpes zoster keratitis had no significant differences (P>0. 05).CONCLUSlON: The change of trace elements and body comprehensive immune state of patients with viral keratitis are obvious, and the severity degree for the detection levels of keratitis are greater.

Objective To evaluate the safety and efficacy of photoselective vaporization of prostate (PVP) for the treatment of benign prostatic hyperplasia (BPH). Methods A total of 161 patients with symptomatic bladder outlet obstruction due to BPH underwent PVP via transurethral with Niagara PV TM system.The therapeutic results were assessed using following variables:the safety and efficacy of sacral anesthesia,blood loss,operative time,indwelling catheterization,mean Qmax,IPSS,QOL and the sexual function. Results The PVP was successfully performed on all the 161 patients with BPH.There were 160 patients under sacral anesthesia and only 1 under epidural anesthesia.The mean operative time was (44.5?22.4)min (range,15～210 min).All patients had minimal or no blood loss and no patients required blood transfusion.No postoperative catheterization was needed in 21 patients. The mean catheterization time was (34.4? 20.8 )h (range,24-72 h).Postoperatively 2 cases had transient dysuria and 2 experienced delayed hematuria.All cases were followed up for 3 to 6 months after treatment.The mean Qmax increased from (6.5? 2.4 )ml/s to (19.8?2.1)ml/s;mean IPSS and QOL decreased to 5.8?1.6 and 1.7?0.4,respectively,which showed significant improvement,compared with those before operation( P

Objective To explore clinical and radiographic outcomes of unstable distal clavicle fractures (Neer ⅡB) fixed with lateral clavicle anatomic locking compression plate (LCP).Methods Between January 2009 and October 2010,eleven consecutive patients with unstable fractures of the distal clavicle (Neer ⅡB) were treated using lateral clavicle anatomic LCP.There were 9 men and 2 women,with the mean age of 37.2 years (range,23-43 years).The right shoulder was involved in 6 patients and the left in 5 patients.The interval between injuries to operation was 24-72 h (mean,48 h).After fracture reduction,the plate was place on superior of the distal clavicle.According to the distal fragment length,3 to 6 locking screws were carefully inserted,3 locking screws were used to fix proximal fractures.Coracoclavicular ligament was not repaired.Functional recovery of the shoulder joint was assessed using the American Shoulder and Elbow Surgeons (ASES) rating scale score.Plain radiographs of clavicles were used to assess bony union.Results All the patients were followed up for 9 to 12 months (mean,10.3 months).Solid bony union was eventually achieved in all patients.The mean ASES scores were 89.1 (range,84-91) on the injured side versus 96.2 (range,94-100) on the contralateral side.No implant-related fracture,fixation failure and rotator cuff injury occurred.Conclusion Lateral clavicle anatomic LCP fixation in the treatment of distal clavicular fractures is a reliable and simple technique.

Objective To quantitatively analysis the aortic valve leaf anatomical characteristics in aortic regurgitation(AR) patients by real-time three-dimensional transesophageal echocardiography (RT-3D-TEE),and screening the parameters which significantly affect AR to further reveal the mechanism of AR.Methods 32 patients with AR were enrolled as AR group and 20 cases of non-AR people were involved as control group.RT-3D-TEE was using to collect images in two groups and offline analysis was performed.4 sets of parameters of the aortic valves(left coronary valve,right coronary valve,and non-coronary valve):leaflet edge length(LL,RL,NL),leaflet height (LH,RH,N H),leaflet length/height ratio (LRa,RRa,NRa),leaflet tip plane distance(LTH,RTH,NTH) were acquired.Parameters of two groups were compared,and the parameters were incorporated into the logistic regression model,then the ROC curves were obtained.Results ①Compared with the control group,LL,RL,NL,RH,LRa,NRa,RRa in AR group increased (P ＜ 0.05),while the rest parameters had no statistical differences (P ＞0.05).②Multivariable logistic regression model gradually screening of the significant factors influencing the reflux,and as a result RL and RTH had significant influence on AR,P values were 0.001,0.011.③The ROC curve analysis showed that the area of RL or RTH curve were both greater than 0.5,which were 0.811 and 0.605 respectively.Conclusions The free edge length and free edge length/height ratio have changed unbalanced.Furthermore,right coronary valve parameters changed significantly,and this might be one of the possible mechanism of AR.

Objective To explore the increment of molluscicidal effect and reduction of the cost as well as increasing snail control area by complex commercial molluscicides. Methods Nicotinanilide and niclosamide were combined with the proportion of 1∶1 (The complex of short term was complex molluscicide), and then the snail control tests by immersion and spraying methods were performed using the complex molluscicide in laboratory and field. Meanwhile, the snails climbing from water as they contacted with molluscicide was observed. Results Under the temperature 23-25℃ in lab and 8-19℃ in the field, 0.4 mg/L of the complex by immersion for 48 h, the mortalities of the snails were 100% and 97% respectively. Using 0.4 g/m 2 of complex by spraying for 48 h in lab and the field, the mortalities of the snails were 100% and 81.1% respectively. The rate of snails climbing from water in the complex group decreased by 72.1% compared with the nicotinanilide group. The difference between the two groups was obviously significant (P

Objective To explore the efficacy and safety of greenlight photoselective vaporization of prostate(PVP) in high-risk older patients with benign prostatic hyperplasia(BPH).Methods A total of 96 high-risk older patients with BPH underwent PVP.The operative time,blood loss,indwelling catheterization and operative complications were observed.The variables such as IPSS,QOL,uroflowmetry,post-void residual urine volume(RUV) were recorded and calculated pre-and post-operatively.Results All the 96 patients safely got through perioperative period.The mean operative time was(24.8?6.5)min,intraoperative blood loss was(55.4?16.8)ml and postoperative indwelling catheterization was(1.6?0.7)d.IPSS and QOL scores decreased form preoperative 29.8?5.2 and 5.2?0.8 to postoperative 8.4?2.3 and(1.4?)0.5,respectively.Qmax increased from(5.6?2.8)ml/s to(16.7?3.2)ml/s,and RUV decreased from(168.0?22.5)ml to(24.6?5.81)ml.There were significant differences of these parameters between pre-and post-operation(P

Objective To investigate methods and clinical effects of limited open reduction of ankle articular surface and locking compression plate (LCP) placement using minimally invasive plate osteosynthesis (MIPO) in managing tibial Pilon fractures.Methods Twenty-one patients with tibial Pilon fractures treated between August 2009 and August 2011 were involved in the study,including 16 males and 5 females,at age of 21-68 years (average 42.3 years).According to AO/OTA classification,12 patients were with type 43B fractures and nine with type 43C fractures.There were two patients with open fractures (both Gustilo-Anderson type Ⅰ fractures).Limited open reduction of ankle articular surface plus LCP placement using MIPO were performed.Early functional training without weight-bearing was carried out postoperatively.Results Nineteen patients were followed up for 12-24 months (average 14 months).According to Burwell-Chamley' s radiological evaluation system,17 patients obtained anatomical reduction of articular surface and two patients obtained moderate reduction,but they all had bony healing.Ankle function evaluated by Mazur' s criterion were excellent in seven patients,good in 10 and fair in two,with excellence rate of 89％.Conclusion Limited open reduction combined with LCP internal fixation can successfully construct articular anatomic relationship,decrease soft tissue dissection and attain solid fixation in treatment of Pilon fractures and further facilitate functional recovery of the affected extremity in coordination with early functional exercise.

Objective To discuss the relations between optimal surgical margin and local recurrence and the impact of preserving segment of sacral nerve root on neural functions based on the clinical and pathological features of giant cell tumor(GCT).Methods From August 1996 to August 2008,48 patients with sacral GCT undergoing tumor resection were respectively analyzed,including 20 males and 28 females with an average of 34.7 years(range,19-74).The tumors were located in S1-S5 in 4 patients,S1-S4 in 7,S1-S3 in 15,S1,2 in 12,S2-S5 in 8,and S3-S5 in 2.Surgical methods included single posterior approach in 29 cases,combined anterior-posterior approach in 19.The surgical margins adopted were en-bloc in 2 patients,marginal in 15,marginal and curettage in 25,and curettage in 9.Results Forty-one of 48 cases were successfully followed up,the average time was 43.5 months(range,18-115).The average blood loss during surgery was 3560 ml(range,550-12 000).Benign lung metastasis occurred in one case 6 years after operation,2 patients died of malignant transformation.Local recurrence occurred in 15 cases.The recurrence rates in patients with en-bloc resection,marginal resection,marginal resection combined with curettage,and curettage were 0,18.2%,40.9%,66.7%,respectively.The recurrence rate of marginal group was significantly lower than that of the curettage group.Of 27 cases with bilateral S3 nerve root preservation,2 sufiered from urine or fetal dysfunction.with an incidence rate of 7.4%.While 4 of 12 patients with unilateral S3 nerve root preservation suffered from sphincter disturbance,with an incidence rate of 33.3%.The significant difference between groups in nerve root preservation was confirmed.Conclusion Optimal surgical margin for sacral GCT is of great importance to local control of tumor recurrence,the surgical procedure of sacral GCT should aim at the marginal resection on the basis of rational sacral nerve roots preservation;preservation of bilateral S3 nerve roots contributes to the recovery of sphincteral function in most patients.
