Chinese Journal of Rehabilitation Theory and Practice 2004;10(6):360-361
ObjectiveTo observe effects of modulated medium frequency low frequency current hydroelectric bath therapy on sequela of ankle fracture.Methods32 sequela patients of ankle fracture were treated with ZM-C type intellectual faculties intermediate frequency therapeutics instrument. Modulated medium frequency square all wave,the frequency of carry wave was 4 KHz,and the frequency of modulated wave was 100 Hz. The water temperature was 40℃. 30 minutes was a time,12 times was a course. Before and after treatment,results were contrasted themselves.ResultsAfter treatment,32 patients all got satisfactory effects,the shorter of the course,the better of the effect.ConclusionThe modulated medium frequency low frequency current hydroelectric bath therapy is a simple,safe and better effect method for sequela of ankle fracture.

Objective To explore the feasibility of low dose in MSCT thoracic angiography using Z-axis modulation. Methods The consecutive 60 patients were averagely divided into 3 groups and underwent thoracic angiography with a Toshiba Aquilion 16 scanner. The whole chest acquisition was commenced in automatic exposure control with Z-axis modulation 20-25 seconds after the contrast material was administered at the rate of 3.5-4. 0 ml/s. With the noise index (SD) as the variable, three study groups were classified as A (SD = 12) , B (SD = 15 ), and C (SD = 18 ). The mAs value per slice and the number of slices were recorded. The noises and artifacts of the axial images and the acceptability of CT angiogram were evaluated. The difference among the groups was compared by using ANOVA or nonparametric Kruskal-Wallis test. The threshold of the P value was 0. 05. Results The mean mAs value (46. 4 ± 15.6) mAs in group A was the highest but the SD value (21.6 ±7.7) was the lowest. The mean mAs value ( 37. 0 ± 13.5 ) and the SD value ( 24. 0 t 5.4 ) in group B were the mediate. The mean mAs value ( 20. 7 ±6.3) mAs in group C was the lowe(s)t but the SD value ( 30. 7 ± 6.9) was the highest ( H = 31. 390, P =0. 000). The middle slice images in all patients had the smallest mAs (40. 9,31.3,17. 1 for group A,B,C,respectively; F =9. 578, H =22. 230, F =21. 180,P =0. 000) and SD values( 16. 3, 20. 0,25.4 for group A,B,C, respectively; H = 28. 982, H = 20. 824, H = 24. 396, P = 0. 000). The acceptability of CT angiogram in all patients was excellent. The CT value of descending aorta in group A, B, and C was ( 335 ± 85 ) HU,(334 ±56)HU, and (427 ± 63 )HU, respectively. Conclusion Low dose in MSCT thoracic angiography using Z-axis modulation is feasible. We can use low dose (20 mAs, etc. ) for CT angiography when the contrast is significant.

Objective Pathogen and antimicrobial susceptibility in children with bacterial meningitis were reviewed.Methods The positive cultures of cerebrospinal fluid samples or blood samples and its antimicrobial susceptibility were analyzed in 401 patients with the clinical diagnosis of bacterial meningitis.Results 401 cases cerebrospinal fluid samples and blood samples submitted to microbiology laboratory, 97 cases (24%) were microscopically and culturally proven to be bacterial meningitis. The most frequent pathogen was staphylococcus aureus (28%), followed by the streptococcus pneumoniae (19%) and escherichia coli (13%). Pediococci as conditioned pathogen, were found in purulent meningitis patients. One of the isolates of Staphylococcus aureus was simultaneously resistant to both vancomycin and teicoplanin. Three isolates showed simultaneous resistance to imipenem/cilastatin.Conclusions Staphylococcus aureus as the predominant pathogens of pediatric ranks first among pediatric patients of purulent meningitis. Serious drug resistance of isolated pathogenic bacteria and its in antimicrobial susceptibility in the bacterial meningitis should be considered in clinical therapy.

AIM:To investigate the differences among Lenstar 900, A-scan ultrasound and keratometer in measurement of axial length ( AL ) , anterior chamber depth ( ACD ) and corneal curvature ( K1 , K2 , Km ) , and evaluate the consistency of the instruments, with the purpose providing references for the clinical application of Lenstar 900.
METHODS: In this study we picked up 36 patients ( 50 eyes ) underwent cataract surgery, and lens nucleus hardness were under level IV. Before the operation, AL, ACD and K1 , K2 , Km were measured by Lenstar 900, A-scan ultrasound and keratometer respectively. The differences between the results were compared by the paired t-test. The correlation of the results was analyzed by Pearson correlation analysis, and the consistency was measured by Bland-Ahamn method.
RESULTS: The mean AL and ACD values measured by Lenstar 900 and A-scan ultrasound had no significantly statistic differences (P>0. 05). The K1, K2, Km measured by Lenstar 900 and keratometer were not significantly statistical different (P>0. 05). The results measured by these three instruments had close linearity correlation ( r>0.9, P<0. 01). The consistency of the results was well in Bland-Ahamn analysis.
CONCLUSION:The preoperatively biometric result of Lenstar 900, A - scan ultrasound and keratometer in patients with cataract are all reliable, and they can be substituted by each other. However, Lenstar 900 can not only measure AL, ACD and corneal curvature at the same time, but also cornal thickness, lens thickness, white to white, pupil size, optical axis eccentricity, retinal thickness and so on. It has a number of advantages such as non-touching, convenient and efficient, and can be recommended to use widely.

Objective To evaluate the remote effect of local injection of botulinum toxin by use of the F-wave measures. Methods The F-wave responses as well as M-waves were recorded before injection, and at 1 week,12 to 24 weeks after local injection of botulinum toxin type-A (BTX-A) in 26 patients, including 19 with hemi-facial spasm (HFS),5 Meige syndrome and 2 torticollis spasmodicus (TS).The following parameters were analyzed: M-wave latency (ML) and amplitude (Mamp), F-wave minimal latency(Fmin) and average latency(Fave),amplitude (Famp), duration (Fdur), persistence (Fper) and chronodispersion (Fchr). The above parameters were obtained through the electric stimulation of ulnar and tibial nerves, and recorded from the abductor digiti minimi and extensor digitorum brevis, respectively. Results No definite F-wave was obtained by electric stimulation of ulnar nerve at 1 week after injection in 3 HFS patients (5 nerves). The Fave recorded from electric stimulation of ulnar and tibial nerves prolonged significantlyand Fdur from ulnar nerve increased significantly at 1 week after injection, but were not significantly different from those of pre-injection when recorded at 12 to 24 weeks after injection. No significant correlation of the altered F-wave parameters was found with the dosage of BTX-A. Conclusion Fdur and Fave could sensitively assess the remote effect of the local injection of BTX-A, the remote effect might be correlated with the distance between injected muscle and tested muscle, rather than the dosage of BTX-A.

OBJECTIVE To discuss the available methods of preventing the mattress pollution in the wards of the(hospital), and to keep the mattresses clean and dry and eliminate the hidden danger of nosocomial infection.(METHODS) The mattress protective covering is used of a new type of textile materials,and then applied into clinic.Selected 100 pieces of mattresses in the wards,divided them equally into two groups at random,the(experimental) group and the control group.After cleaning and pasteurization(surface) sampling and bacterial culturing for every mattress were undertaken.For the experimental group,spread the protective(covering) before the sheet,and for the control group,used the sheet directly.The colony number of each group was compared in the 3rd,7th,and 14th days.RESULTS The mattresses of experimental group were clean,light polluted and with less colonies,and that of the control group were heavy polluted and with more colonies.The comparisons of the total colony number and the number of every sampling point in the 3rd,7th,and 14th days of the two groups showed that there was a(significant) difference(P
