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:To explore the antibacterial effect of Belamcanda Chinensis DC and Por tulaca oleracece L on P.aeruginosa (PA) in vitro.Methods:Fourty six strains PA were tested for minimum inhibition concentrati on ( MIC) by water decoct agents of the two drugs.MIC50 and MIC90 were st atistically studied.Results:For Belamcanda Chinensis DC,MIC was 31.25～3.90 g/L;MIC50 was 7 .81 g/L,and MIC90 was 15.62 g/L;whereas， for portulaca oleracece L,MIC was 31 .25～7.81 g/L, MIC50 was 15.62 g/L,and MIC90 was 31.25 g/L.Conclusion:Both of the two drugs have stronger antibacterial effects on P.ae ruginsosa in vitro.

OBJECTIVETo explore the curative effect and safety of acupuncture for mild cognitive disorders after stroke.

METHODSRandomized controlled trial was adopted and one hundred cases conforming to criteria were divided into a combined acupuncture and medication group (group A) and a medication group (group B), 50 cases in each group. The basic treatment of cerebrovascular disease was applied in two groups. The group A treated was with acupuncture at Baihui (GV 20), Shenting (GV 24) and Qucha (BL 4) etc. and oral administration of Nimodipine. In group B, Nimodipine was taken orally. The treatment lasted for 3 months, the scores of Mini-Mental State Examination (MMSE), modified Hasegawa Dementia Scale (HDS-R) and Barthel Index (BI) were observed before and after treatment in two groups.

RESULTSThe total effective rate in group A was 66.7% (32/48), which was superior to 30.4% (14/46) in group B (P < 0.05). The scores of MMSE, HDS-R and BI after treatment were apparently improved as compared with those before treatment in two groups (all P < 0.01). The improvements in group A were superior to those in group B (all P < 0.05). There was no adverse event reported during the treatment in two groups.

CONCLUSIONAcupuncture can improve activity of daily living and has significant effect in treating mild cognition disorders after stroke without adverse reactions.

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
