OBJECTIVE To investigate the time and dose relation of new urine bio markers in rat model of acute kidney injury induced by genta mycin (GM)to search for more sensitive,noninvasive and specific markers than traditional approaches to monitor nephrotoxicity.METHODS SD Rats were im treated with GM5,20,80 mg·kg -1 or saline once daily.Rats were randomly divided into 20 subgroups:treated for 1 ,3,7,14 d and 14 d followed with 28 d recovery period.Ten rats per group (5 rats per sex)were scarified at 24 h after the last dosing or the end of recovery period.Blood sa mples were col-lected for blood urea nitrogen (BUN)and creatinine(CRE)analysis.Urine was collected at each nec-ropsy for urine protein by dry che mistry method,for kidney injury molecule-1 (KIM-1 )analysis by ELISA, and for β2-microglobulin (β2-MG)analysis by ELISA.Kidneys were obtained for histological exa mination after HE stains.RESULTS Positive protein(3 +)was noted for several fe male animals treated for 7 or 14 d at 80 mg·kg -1 and the tendency of recovery were noted at the end of recovery period.Co mpared with those in saline control group treated for 7 d,the seru m BUN and CRE levels for fe males and the CRE level for males were significantly increased at 80 mg·kg -1 (P <0.05),and the BUN level showed the tendency of increase for males at 80 mg·kg -1 (P >0.05).When treated for 14 d,the seru m BUN and CRE levels for fe males and males at 80 mg·kg -1 and the seru m CRE level for fe males at 20 mg·kg -1 were significantly increased when compared with those in saline control group(P <0.05). The seru m BUN and CRE recovered to base line for all animals treated for 14 d followed by a 28 d recov-ery period.Histopathological observation of kidney tissues indicated that focal tubule dilatation was noted for animals treated for 3 d at 20 and 80 mg·kg -1 ,infla mmatory cell infiltration and focal tubule dilatation were noted at 20 mg·kg -1 and focal renal tubular epithelial cell degeneration,infla mmatory cell infiltra-tion,focal casts (lightly)were noted at 80 mg·kg -1 for animals treated for 7 or 14 d.For animals treated for 14 d followed by a 28 d recovery period,only basophilic tubules and renal casts were noted at 80 mg·kg -1 .New urine bio markers determination indicated that KIM-1 level was significantly increased at 20 and 80 mg·kg -1 for animals treated for 3,7 or 14 d when compared with that in saline control group (P<0.05).For animals treated for 14 d followed by a 28 d recovery period,the KIM-1 level was still significantly higher than saline control group for males and fe males at 80 mg·kg -1 and males at 20 mg·kg -1 (P <0.05 ),but there was evidence for reversal.The β2-MG level was significantly increased at 80 mg·kg -1 for animals treated for 3 d(P<0.05),at 20 or 80 mg·kg -1 for animals treated for 7 or 14 d(P<0.05 or P<0.01 ),when compared with that in the saline control group.For animals treated for 14 d followed by a 28 d recovery period,the β2-MG level was still significantly higher than saline control group for males and fe males at 80 mg·kg -1 and fe males at 20 mg·kg -1 (P <0.05),but there was also evidence for reversal.CONCLUSION Urine KIM-1 and β2-GM are more sensitive and specific markers for early diagnosis of kidney injury induced by GM when compared with the traditional approaches to monitor nephrotoxicity.

Objectives To study the psychological characteristics of children with attention deifcit hyperactivity disorder (ADHD). Methods Human ifgure drawings (HFD) as a projective technique was performed in 107 children with ADHD aged (8.69 ±1.48) years old (6.5~11.5 years), and 107 matched healthy children. Characteristic features of the HFDs in children with ADHD, and correlations between emotional indicators of the HFDs and factors of child behavior checklist (CBCL) were assessed and com-pared with the control group. Results Signiifcant differences in emotional index were found between ADHD and healthy chil-dren, including bad body composition, short arms, long arms, big ifgure, omission of hands and omission of feet (P<0.05). Nega-tive correlation was found between the HFDs emotional index and the factors of activity and social ability in the CBCL (P<0.05), but a positive correlation was found between the HFDs emotional index and behavioral problem (P<0.05). Conclusion Human ifgure drawings can relfect some emotional characteristics of children with ADHD, and when combined with CBCL, it can pro-vide evidence for diagnosis and intervention for ADHD.

Objective To explore the effect of Da Vinci robot?assisted laparoscopic radical prostatecto?my on the respiratory function of elderly in Intensive Care Units( ICU) . Methods Thirty?nine elderly patients received Da Vinci robot?assisted laparoscopic radical prostatectomy ( RARP ) from January 2015 to April 2016 and 25 cases received conventional laparoscopic radical prostatectomy from January 2014 to December 2014 ad?mitted into ICU were retrospectively analyzed. Their comorbidities,blood loss and transfusion during surgery,ate?rial blood gas(ABG) analysis and respiratory complications after operation,clinical outcomes between the two groups were compared. Results Compared with conventional laparoscopic radical prostatectomy,RARP group spent more time in surgery((4. 23±1. 44) h vs. (3. 25±1. 31) h,t=2. 783,P<0. 05),more patients need venti?lation(11 vs. 1,χ2=4. 378,P<0. 05) . ABG analysis showed respiratory and metabolic acidosis with lower pH (7. 29±0. 09 vs. 7. 35±0. 05,t=3. 886,P<0. 05),HCO3?((20. 05±2. 50) mmol/L vs. (22. 86±2. 53) mmol/L,t=3. 473,P<0. 05),BE(-5. 11±3. 94 vs.-3. 64±1. 17,t=5. 018,P<0. 05) and higher pCO2(46. 15±8. 31 vs. 40. 25±6. 57,t=2. 475,P<0. 05),Lac((3. 54±1. 99) mmol/L vs. (2. 91±1. 39) mmol/L,t=2. 254,P<0. 05) . Conclusion RARP may cause carbon dioxide retention and respiratory complications on elderly pa?tients. It may reduce postoperative respiratory complications by shortening surgery time,lowering pneumoperitone?um pressure,hyperventilation,recruitment maneuvers and chest physical therapy.

AlM: To compare the results of 4 methods for measuring angle of exodeviation in the three types of intermittent exotropia, including when looking at indoor distance target of 6m, looking at indoor distance target of 30m, looking at outdoor far distance target, after 1h diagnostic occlusion test.
METHODS: Prospective case series study. Sixty-five patients with intermittent exotropia between June 2013 and June 2014 were enrolled in the Department of Ophthalmology, Affiliated Hospital to Qingdao University, included 37 males and 28 females with average age ( 12. 5 ± 6. 2 ) years. All the patients were measured when looking at indoor distance target of 6m, looking at indoor distance target of 30m, looking at outdoor far distance target, after 1h diagnostic occlusion test. lntermittent exotropia was divided into basic type, convergence insufficiency type and divergence excess type, which was based on the different result of between the distance and near measurements. The One-way test was applied to analyze the four methods of measuring angle of exodeviation in the three types of intermittent exotropia. LSD - t test was applied to compare the differences between each two methods in each type.
RESULTS: The distance exodeviations tested with looking at indoor distance target of 6m, looking at indoor distance target of 30m , looking at outdoor far distance target, after 1h diagnostic occlusion test were basic type (45. 4 ± 21. 0, 55. 0 ± 15. 0, 64. 68 ± 17. 7, 68. 75 ± 16. 6PD), convergence insufficiency type (33. 3 ± 14. 0, 44. 9 ± 12. 9, 43. 6±11. 8, 54. 6±11. 2PD), divergence excess type (55. 6± 17.4, 66.3±18.8, 76.9±16.4, 78.1±15.6PD). There were obviously differences between each two methods in each type ( basic type F = 9. 649, P = 0. 00; convergence insufficiency type F=6. 886, P=0. 001; divergence excess type F = 7. 989, P = 0. 00 ). Compared with looking at indoor distance target of 30m, looking at outdoor far distance target ( basic type P=0. 044, divergence excess type P = 0. 048 ) and after 1h diagnostic occlusion test (basic type P=0. 04, divergence excess type P=0. 027) had the statistical difference in the basic type and divergence excess type, and there was no obviously difference between looking at outdoor far distance target and after 1h diagnostic occlusion test ( basic type P=0. 353, divergence excess type P=0. 815). Compared with the other three measurements, 1h diagnostic occlusion test can elicit larger angle of deviation in the convergence insufficiency type.
CONCLUSlON: Both measurement with looking at outdoor far distance target and after 1h diagnostic occlusion test can elicit the larger angle of deviation in the basic type and divergence excess type; The measurement with after 1 hour diagnostic occlusion test can elicit the larger angle of deviation in the convergence insufficiency type.

Objective To investigate safety and efficacy of hysteroscopy in treatment of cesarean scar pregnancy(CSP).Methods From Aug.2003 to Dec.2011, 33 cases with CSP treated by hysteroscopy guided by transabdominal ultrasound or laparoscopy were studied retrospectively in Women's Hospital,School of Medicine, Zhejiang University.The clinical characteristics including gestational age, myometrial thickness anterior to the CSP, β-hCG level before treatment,success rate, cure rate, operative time, blood loss, time of serum β-hCG resolution and CSP mass clearance, and complication were collected and analyzed.Results Median gestational age was 54 days (range, 37 - 140 days).Median level of β-hCG before treatment was 15 000 U/L( range,3.3 - 151 747 U/L).Mean thickness of anterior myometrium was 3.3 mm.Twenty-nine cases underwent uterine artery embolism (UAE) before hysteroscopy.Pouch in the anterior uterine isthmus with gestation masses implanted were observed in 30 cases (91%, 30/33 ).CSP masses progressed toward the pouch or uterine cavity in all cases was removed by cutting wire loop electrode combined with curettage.The mean operative time was (34 ± 10) minutes.Both success rate and cure rate were 94% ( 31/33 ) .Salvage methotrexate ( MTX ) therapy was administrated in one case.Complication occurred in three cases (9%, 3/33 ).Both massive hemorrhage rate and hysterectomy rate were performed in two cases (6%, 2/33).No uterine perforation occurred.The mean time of hCG resolution was (22 ± 10)days.The mean time of CSP mass clearance was (21 ± 12) days.Four pregnancies were achieved in four cases:one term pregnancy and three abortions.No recurrent CSP occurred.Conclusion Management of CSP by hysteroscopy combined with UAE is safe and effective.
