ABSTRACT
Objective:To compare the detective effect between color Doppler twinkling artifact and B-mode ultrasonography for kidney stones in order to develop an ultrasonic model that can more easily and more accurately detect kidney stone.Methods: 9 patients with kidney stone who were confirmed by CT scan in recently were selected to accepted two methods (color Doppler twinkling artifact and B-mode ultrasonography) to detect kidney stone. The video fragments of upper pole, interpolar and lower pole were created by three radiologists and the results were diagnosed by them.Results: In dual kidneys of the nine patients, 32 stones with average size of (8.9±7.5) mm were found. The sensitivity, specificity, positive predictive value and negative predictive value of the B-mode ultrasonography were 71%, 48%, 52% and 68%, respectively, while those of color Doppler twinkling artifact were 56%, 74%, 62% and 68%, respectively.Conclusions: In the detection of kidney stones, B-mode ultrasonography is more sensitive when is used alone, but color Doppler twinkling artifact has more high specificity. The color Doppler twinkling artifact should be applied in more clinical practices, and a new commercial ultrasonography mode that used basic acoustic difference and is special for detection of kidney stone should be researched and developed so as to improve the detection of kidney stone.
ABSTRACT
Jingui Yaolue is a part ofTreatise on Cold-Attack and Miscellaneous Diseases. Because of the archaic words, students lost the interest on it. So it became the questions that how to make students interested in learning theJingui Yaolue and to make traditional Chinese medicine(TCM) classical guide clinical treatment. Thus, a try has been made to teach the TCM classic in the clinical practice apprentice setting rather than the classrooms. Here, some experiences about apprentice teaching in clinical practice of Jingui Yaolue were shared.
ABSTRACT
OBJECTIVE:To offer the literature basis for clinical safe drug use by literature research about ADR induced by Yishen juanbi pill. METHODS:Using“Yishen juanbi pill”as searching word,related literatures about ADR induced by Yishen juanbi pill were collected from CNKI,and then the occurrence of ADR was summarized and analyzed. RESULTS:A total of 15 literatures were included,involving 58 patients. Primary disease were mainly rheumatoid arthritis (28 cases,48.28%);organs/systems involved in ADR were digestive system (77 cases, 76.24%). Main clinical manifestations were epigastric discomfort, pernicious vomiting,diarrhea,etc. No obvious ADR was found. ADR-inducing dose was mainly 8 g,tid(47 cases,92.16%);ADR-inducing drug combination were two-drug combination (33 cases,56.90%). Fifty-eighe cases of ADR were recovered after treatment,and main treatment was drug withdrawal or symptomatic treatment. CONCLUSIONS:Although Yishen juanbi pill may induce ADR,those ADR can disappear spontaneously after drug withdrawal or the symptoms are recovered after symptomatic treatment. Yishen juanbi pill is a relatively safe Chinese patent medicine of anti-inflammatory,but ADR monitoring should be strengthened during application.
ABSTRACT
Erythrocytes were frozen with DMSO of different concentrations (not over 20%) as a cryoprotec-tive agent in freezers of different temperatures.The rate of temperature drop was not controlled. Of the erythrocytes actually frozen, the average recovery rate after thawing was 91.3 per cent (range 87.5~ 95%). The average survival rate of erythrocytes stored at -20℃, -30℃, or -80℃ for up to eight months was 90.9 per cent (range 88.2~ 94.5). As compared with glycerol, which is in common use internationally, DMSO seems to be a better cryoprotective agent.
