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 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.

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.

Objective To investigate CT features of solitary fibrous tumor of the mediastinum(SFTM),and to analyze the causes of misdiagnosis of this disease.Methods CT features of 5 patients of SFTM confirmed operatively and pathologically were retrospec-tively analyzed.All patients underwent before operation but were misdiagnosed.Results 3 cases were located in right mediastinum with oval-shap,well-defined margin,and “pleural tail sign”,2 cases were located in right thoracis cavity with unwell-defined margin, and in the adjacent lung were oppressed.In all 5 patients,the mean median of tumors was 1 1.5 cm(8.6-1 5 cm),non-homogeneous density of tumors were seen on plain CT scans,and obvious non-homogeneous enhancement with“geographic pattern”on contrast-en-hanced CT.Conclusion CT can clearly reveal the size and the appearance of SFTM,adjacent architectures,the final diagnosis de-pends on histopathological and immunohistochemical findings of the tumors.To un-know is the main caused of misdiagnosis of medi-astinal SFT.
