Percutaneous transluminal coronary angioplasty (PTCA) was done successfully in 33 patients,6 of them were associated with 8 acute coronary events. Radioimmunoassay was used for the determination of plasmaET,AII and CGRP levels. The samples were drawn successively from femoral artery just before PTCA and 0min, 15min,1h,3h,24h after the final balloon inflation. The results showed that the levels of plasma AII were higher in the complication group than those of noncomplication group before PTCA and 0min, 24h after PTCA. The differences in plasma ET levels before and after PTCA between the complication group and the non-complication group were not significant. The level of plasma CGRP was decreased at 15min and returned to basal level at 1h after PTCA in the complication group.In the patients without complication,there were no significant differences in their plasma CGRP levels before and after PTCA. All + ET/CGRP in the complication group raised more rapidly,recovered later and the peak appeared earlier than that of non-complication group. For a better understanding pathophysiologic meaning of the above changes,further studies are needed.

BACKGROUND: Transcranial Doppler(TCD) spectrum analysis techniques cannot measure the diameters of blood vessels and therefore and not be used to calculate the changes of brain blood flow. A formula was designed for regional cerebral blood flow loss index(rCBFLI) following arteriostenosis when arteriostenosis index formula was deduced; the former may provide a reference to assess cerebral function.OBJECTIVE: To introduce the formula of cerebral blood flow loss ratio obtained basing on TCD results.DESIGN: Retrospective controlled study based on patients with cerebral middle arteriostenosis diagnosed with TCD and healthy people.SETTING: At the departments of neurology in a university hospital and in a military medical university affiliated hospital of Chinese PLA.PARTICIPANTS: Between October 1994 and December 2000,43 patients who were confirmed of arteriostenosis with TCD at outpatient or neurological ward of the First Affiliated Hospital of Fujian Medical University were enrolled into this study,and their TCD results were compared with 908 normal controls between March 1992 and September 2000.METHODS: Stenosis index (STI) formula was deduced from TCD results of 31unilateral and 12 bilateral stenoses at middle cerebral artery(MCA) . STI = 1- [ normal average blood velocity (Vm0) ÷ average blood velocity at stenosisSince(PI1 ÷PI0) may be equal to [post-stenosis blood flow(Q1) ÷ normal blood flow(Q0)],regional cerebral blood flow loss index is concluded as:MAIN OUTCOME MEASURES: rCBFLI,relationship between STI and Vm,as well as between rCBFLI and STI.RESULTS: rCBFLI formula was used to calculate the rCBFLI of 31 patients following unilateral MCA stenosis. rCBFLI of these 31 patients was obtained by Pearson statistical analysis. STI was found to be related to the average blood velocity at stenosis with relative coefficient(Vm) of(r) =0.76( P < 0. 001 )and r = 0. 83 ( P < 0. 001 ) . rCBFLI was proved to be correlated with Vm and STI with r = 0. 76( P < 0. 01 ) and r = 0. 81 in 55 side MCA stenoses,and the difference was of statistical significance( P < 0. 001 ).CONCLUSION: rCBFLI can be used to assess the decrement of regional brain blood flow due to the stenosis of supplying artery; also,it can be used to observe the changes of brain hemodynamics if combined with STI.

Objective To study common Gram negative bacterial pathogens and their drug resistant pattern in sputum isolates from patients in pediatric intensive care unit (PICU) of Chengdu children' s hospital. Methods Comparing to the period of 2004-2006 with 2007-2009, we retrospectively reviewed eligible sputum isolates of common Gram negative bacilli and their drug resistance pattern. All specimens were processed according to standard microbiological methods for both quantitative and qualitative cultures. Pathogen was the single predominant growth after two consecutive cultures. Strict quality control was used in all test agents and paper disk for drug resistance analysis. Results Total of 598 Gram negative bacterial isolates were identified in patients over 6 years. The first 5 bacteria respectively were Escherichia coli 167 samples(27.93%), Klebsiella pneumoniae 109 samples ( 18.23% ), Enterobacter cloacae 93 samples ( 15.55% ),Acinetobacter baumannii 64 samples ( 10. 7% ), Pseudomonas aeroginosa 43 samples (7. 19% ). They were mostly sensitive to Imipenam, Amikacin, Piperacillin/Tazobactam. Most drug resistance rate was found in Amoxicillin, Ampicillin, Cephalosporin. Apart from Pseudomonas aeroginosa and Acinetobacter Baumannii,no Gram negative bacteria was found to be resistant to Imipenam. Klebsiella pneumoniae and ESBL secreting Escherichia coli isolates were obviously increasing when compared to 3 years ago. Conclusion Comparing the period of 2004-2006, the Gram negative bacterial isolates were increasing in our PICU patients during 2007 to 2009. Close monitoring of drug resistance pattern changes in PICU would guide rational use of antibiotics in these critically ill children.

[Objective] The present study aimed to determine the protective role of Melatonin (MT) against Acrylamide (AA)-induced testicular toxicity and the potential molecular mechanism.[Methods] The animals were randomly divided into three groups,the control group (n =12),the AA group (n =12) and the AA+MT group (n =12).The rats in the AA and AA + MT group were gavaged with AA at a dose of 15 mg/(kg · day) for 4 consecutive weeks.After 3 weeks of AA treatment,MT was intraperitoneally injected 30 minutes before AA treatment at 10 mg/(kg· day) for 1 week in the AA + MT rats.Subsequently,the mitochondrial membrane potential measurement,TUNEL assay,Western blot and electron microscopic techniques were applied in the present study.[Results] The results showed that AA could decrease the testis mitochondrial membrane potential (P < 0.05) which could be recovered by MT (P < 0.05).Moreover,MT induced down-regulation of Bax expression and up-regulation of Bcl-2 expression in the testis,compared with AA rats.The amelioration of testicular apoptosis was further confirmed by the TUNEL labeling.Western blot results suggested that the decreased ratios of Bcl-2/Bax and Bcl-xL/Bak in the AA group (both P < 0.05) could be recovered by MT treatment (both P < 0.05).The levels of Cyt-c,Casp-3,p53 and NF-κB in AA group were markedly elevated compared with the control (all P < 0.05),and reduced in MT treatment group (all P < 0.05).MT could relieve abnormal mitochondrial structures in the seminiferous tubule in the electron microscopic level.[Conclusion] MT may exert productive effect through its anti-apoptotic properties associated with mitochondria.
