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.

Objective To discuss the ultrasound imaging of acardia twin before and after spontaneously blood blocked in twin reversed arterial perfusion sequence (TRAP), and to analyze the inlfuence factor for the prognosis of pump twin. Methods Seven TRAP with pump twins and acardia′s blood lfow blocked were diagnosed by US and autopsy in Hubei Women and Children′s Hospital between 2001 January to 2012 September. The ultrasound images, clinical data and pump twin’ outcome were analyzed. Results Ultrasound images showed skin edema, acardia, spine and lower limbs in seven acardia cases before blood blocked, among which 4 were acardius acephalus, 3 were acardius anceps. Single umbilical artery were detected in 7 cases with reversed umbilical artery perfusion toward fetus. Four cases had rare blood lfow (UA-PI ratio<0.7. Five acardia cases had slower growing rate than the pump twin. Ultrasound images showed no growing, no blood lfow in the acardia, the acardia twin became vagued in the second and third trimester, and ifnally developed into a paper fetus. A linear umbilical cord extend from umbilical region to placenta were found in 7 cases whose blood lfow were spontaneously blocked. Pump twin′s outcome:3 pump twins survived, 3 died in uterus, and 1 was induced labor due to hydrocephalus and cardiac failure. The most important factors that affected the prognosis of pump twin included:faster growing in acardia twin with less blood supply, abnormal brain and heart function in pump twin, chromosome abnormalities, abnormal amniotic fluid and cord entanglement. Conclusions Less blood flow and slow growth speed prompt in acardia twin suggested spontaneously acardia blood block. It is mandatory to monitor the pump twin after the spontaneous block of acardiac’s blood lfow.

Background The advantages of endothelium keratoplasty(EK)include without corneal surface incision and sutures,remaining normal corneal topography,minimizing astigmatism and providing a healthy donor endothelial cell count and function.Using anterior segment optical coherence tomography(AS-OCT) to examine the morphology of the corneal graft after EK is helpful for the evaluation of the outcome of EK.ObjectiveThis study applies AS-OCT to observe the relationship of recipient cornea and donor graft and offer a basis for the evaluation of operative outcome.MethodsThe clinical data from 44 eyes of 42 patient who received DSAEK in Peking University Eye Center from September 2007 through April 2009 was reviewed retrospectively.These patients included 30 male and 12 female with the age from 15 to 83 years.Structure of cornea and relationship between recipient cornea and graft disc after surgery were clinically examined and recorded by slit-lamp digital camera and AS-OCT.This study was approved by the Ethics Committee of Peking University.Written informed consent was obtained from all of the patients before the operation.ResultsThe donor graft attached to posterior central surface of recipient in 28 eyes under the slit-lamp microscopy and AS-OCT.The thickness of donor graft was decreased,and graft sticked more closely to recipient cornea and was more transparent with the lapse of time.Complete dislocation of the donor graft in early stage was found in 5 eyes(11.36%) and partial dislocation in 2 eyes(4.55%).Curliness of graft edge occurred in 1 eye(2.27%) and eccentricity of donor graft in 8 eyes(18.18%).ConclusionAS-OCT can display the morphology and structure of cornea as well as the relationship between donor graft and recipient after DSAEK.It is helpful for evaluating the clinical effectiveness of DSAEK.

OBJECTIVETo explore the anesthetic effect of preemptive analgesia of frequency acupoint electrical stimulation on painless-induced abortion as well as its effect on anesthetics dosage.

METHODSNinety cases of early pregnancy who selected painless-induced abortion were randomly divided into two groups, 45 cases in each group. Frequency acupoint electrical stimulation at Ciliao (BL 32) and Shenshu (BL 23), disperse-densewave, 2 Hz/100 Hz in frequency for 15 to 20 min, was applied in the group A, which was followed by intravenous anesthesia of propofol. The intravenous anesthesia of propofol was applied in the group B. The blood pressure (BP), heart rate (HR) and SpO2 before, during and after surgery, anesthetic effect and dosage, waking time and adverse events were observed in the two groups.

RESULTSThe BP and HR during and after the surgery in the group A were not statistically different from those before the surgery (all P > 0.05). The BP was reduced and HR was slowed down during the surgery in the group B, which was significantly different from those before the surgery as well as those in the group A (all P < 0.05). The dosage of propofol was (114. 3-+6. 1) mg in the group A. obviously less than (193.2 +/- 8.9) mg in the group B (P < 0.05). The waking time was (5.6 +/- 1.2) min in the group A, obviously less than (10.1 +/- 3.9) min in the group B (P < 0.05). As for anesthetic effect, the incidence of Grade I in the group A was more than the group B (P < 0.05). The adverse events, including nausea, vomiting and contractions pain in the group A were evidently less than those in the group B (all P < 0.05).

CONCLUSIONThe preemptive analgesia of frequency acupoint electrical stimulation could significantly improve anesthetic effect of painless-induced abortion, reduce dosage of anesthetics, shorten waking time of surgery and guarantee the safety of surgery.
