Objective To explore the pulsed wave Doppler (PWD) manifestations of acute experimental incomplete testicular torsion. Methods Eight healthy dogs were surgically modeled to obtain unilateral acute testis torsion from 180° to 630°, respectively. The peak systole velocity (PSV) and resistance index (RI) of intratesticular artery, capsular artery and arteria spermatica interna were measured with PWD before torsion, 2 h, 4 h and 6 h after torsion. Testes were examined pathologically after the experiment. Results PSV and RI of capsular artery and intratesticular artery decreased gradually with the extension of torsional time (P<0.05). PSV and RI of superior, torsional and inferior segments of arteria spermatica interna varied greatly and showed no strong regularity (P＞0.05) . The pathological results of testes showed no distinct changes or just mild interstitial hyperemia and edema. Conclusion The decrease of PSV and RI of capsular artery and intratesticular artery, especially RI have referential value in the judgement of acute experimental incomplete testicular torsion, whereas changes of PSV and RI of superior, torsional and inferior segments of arteria spermatica interna are not reliable.

Objective To analysis the genetic context of armA gene identified in different species .Methods BLASTN searches were used to analysis sequences harboring armA submitted to the GenBank database .Results armA gene was mostly found down-stream of ISCR1 element and was most commonly detected in Enterobacter spp ..Its flanking sequences were highly conserved in Enterobacter spp ..Conclusion The genetic context of armA gene reported in different species scattered in different geometrical lo-cations share some common characteristics .

Objective To discuss the efficacy of alprostadil and levocarnitine in treatment of chronic renal failure combined with heart failure.Methods Totally 80 patients with chronic renal failure complicated with heart failure were selected,and randomly divided into two groups.The control group (39 cases) was given alprostadil.The observation group (41 cases) was given alprostadil and levocarnitine.The efficacy of alprostadil and levocamitine in treatment of chronic renal failure combined with heart failure was evaluated by cardiac fimction indexes,renal function indexes,SF-36 scale score,and adverse reaction during the treatment.Results Before treatment,there was no statistical significance on CO,CI,MVO,and EF between two groups.After treatment,the CO,CI,and MVO were decreased and lower in the observation group (P ＜ 0.05).The EF was increased in the observation group and higher than that of the control group (P ＜ 0.05).The EF had no changes in the control group.Before treatment,there was no statistical significance on CysC,BUN,and SCr between two groups before treatment,without statistical significance.After treatment,CysC,BUN,and SCr were decreased in two groups and lower in the observation group (P ＜ 0.05).Before treatment,there was no statistical significance on SF-36 scores between two groups.After treatment,the physiological function,physical function,and general health were higher than those of the control group (P ＜ 0.05).There was no statistical significance on the rest of the scores.During treatment,there was no statistical significance on adverse reaction between two groups.Conclusion Alprostadil and levocarnitine had a good curative effect on chronic renal failure combined with heart failure.It could improve the heart function by reducing cardiac load,improve the renal function by increasing glomerular filtration rate and improve the quality of life with good safety.It is worthy of clinical application.

OBJECTIVE:To observe the clinical efficacy of acupoint application of antiemetic cream in the treatment of che-motherapy-induced nausea and vomiting. METHODS:90 cases of non-small cell lung cancer(NSCLC)(stage Ⅱ to Ⅲ)treated by chemotherapy(taxol+cisplatin)were randomly divided into antiemetic cream group,Weifuan group and control group,with 30 cas-es in each groupby drawing lots. Control group was given intravenous injection of ondansetron hydrochloride 8 mg 30 min before chemotherapy;antiemetic cream group was additionally given acupoint application of antiemetic cream 30 min before medication on first-forth day on the basis of control group;Weifuan group was additionally given acupoint injection of metoclopramide(brand name:Weifuan) 30 min before medication on first-forth day on the basis of control group. The clinical efficacy of 3 groups were observed during and 3 days after chemotherapy. RESULTS:After chemotherapy,the total control rates of antiemetic cream group (93.33%)and Weifuan group(90.00%)were apparently higher than the control group(66.67%),with statistical significance(P<0.01 or P<0.05);The total effective rates of TCM syndrome in antiemetic cream group (90.00%) and Weifuan group(83.33%) were apparently higher than in control group(60.00%),with statistical significance(P<0.01 or P<0.05). Therapeutic efficacy of antiemetic cream group was similar to Weifuan group,without any statistical significance(P>0.05). However,8 patients had obvi-ously pain at the injection site in Weifuan group,but tolerated to the drugs basically. CONCLUSIONS:The acupoint application of antiemetic cream combined with intravenous injection of ondansetron is effective and easy to operate in the treatment of nausea and vomiting induced by chemotherapy for stage Ⅱ to Ⅲ of NSCLC without pain,scar and sequela,and easy to be accepted by patients.

Objective To investigate the clinical efficacy of acupoint transdermal administered aniemetic herbal plaster combined with intraveous ondansetron preventing chemotheray -induced vomiting .Methods 98 cases of malignant tumor chemotherapy patients were randomly divided into the treatment group of 49 patients and a control group of 49 patients.The treatment group were acupoint transdermal administered animetic herbal plaster combined with intravenous ondansetron while the control group were intravenously administered ondansetron .The clinical effica-cy of preventing chemotheray-induced vomiting was observed .Results The total effective control rate of the treatment group was 93.9% compared with 79.6% of the control group,the efficacy of the treatment group was significantly greater than that in the control group ( P<0.05 ) .Conclusion The antiemetic herbal plaster exhibited significant effect on preventing chemotherapy-induced vomiting after acupoint transdermal application combined with intravenous ondansetron .

AIM: To investigate the electrophysiological characteristics of ventricular myocyte both in subendocardium and in subepicardium during ischemia. METHODS: Using modified Ferrier's method of ischemic and reperfusion injury in isolated guinea pig right ventricular wall. RESULTS: The transmembranal electric activities in subendocardium and in subepicardium were all significantly abnormal, and it was more significant in subendocardium. CONCLUSION: The alteration degree of ventricular myocyte in subendocardium and in subepicardium during ischemia and early reperfusion was different, and this might be the electrophysiological basis of the vulnerability of the subendocardium.

Objective To understand antimicrobial resistance and homology of carbapenem-resistant Klebsiella pneumoniae (CRKP)from an intensive care unit (ICU).Methods 11 CRKP isolates from patients and environment of an ICU in a hospital were performed antimicrobial susceptibility testing,the homology of CRKP was analyzed by randomly amplified polymorphic DNA (RAPD)method.Results Of 11 CRKP isolates,8 were from patients,and 3 from environment,the main specimen was sputum(n =6,54.55%).Antimicrobial susceptibility testing results re-vealed that 10 (90.91%)CRKP isolates were resistant to ciprofloxacin;11 isolates were susceptible to compound sulfame-thoxazole,intermediate to imipenem,and resistant to other antimicrobial agents(100%).All 11 CRKP isolates had 3 bands,and were divided into two types:(typeⅠ,n=10;type Ⅱ,n=1).Conclusion Antimicrobial resistance of Kleb-siella pneumoniae in ICU is serious,CRKP isolated from ICU patients and environment are of the same clone. Cleaning,disinfection,and monitoring of ICU environment should be strengthened,which is helpful for reducing, timely warning of multidrug-resistant organisms,and reducing healthcare-associated infection.
