ABSTRACT
Objective To discuss the effects of a leg positioning straps in painless induced abortion. Methods This study selected a total of 210 cases with unintended pregnant women who volunteered to perform the painless induced abortion from August to December in 2016. Patients were divided into control group(105 cases,taking the traditional leg fixing way)and experimental group(105 cases,fixing knee with leg positioning straps)by random digits table method.Two groups were performed by the same anesthetist and doctor. The operation time, intraoperative blood loss, intraoperative adverse reactions and satisfaction were observed and compared between the 2 groups. Results The operation time and hemorrhage was(8.07±1.80)min,(12.23±5.97)ml in experimental group,and (11.01±2.63)min, (20.03 ± 8.85)ml in control group, and there was significant difference(t=7.491, 9.451, all P=0.000).The incidence of leg moves, equipment moves, leg discomfortable was 0, 1.0%(1/105), 1.9%(2/105) in experimental group and 28.6%(30/105), 8.6%(9/105), 12.4%(13/105)in control group, and there was significant difference (χ2=35.00, 6.72, 8.69, all P<0.05). In experimental group, 68 cases was very satisfied,35 cases were satisfied,2 cases were not satisfied,the control group was 39,52,14,respectively, and the satisfaction between the 2 groups was statistically significant(χ2=20.182,P=0.000). Conclusions The leg positioning straps is not only convenient, safe, steady, humanistic but also decreasing the incidence of adverse reaction and enhancing the medical staff's working efficiency. It is worth of more popular application in clinical operation.
ABSTRACT
Objective To evaluate the treatment effect of compound Chinese medicine on skeletal fluorosis in rats by Micro-CT.Methods Eighty-eight Wistar rats which had been weaned for two weeks were divided into four groups according to body weight [(91.1 ± 10.0)g] by the method of random number table:control group(16 mts),middle fluorine(MF)group(24 rats),high fluorine(HF) group(24 rats),and high fluoride and low calcium low protein (HF-LC-LP) group (24 rats).The amounts of fluorine of MF,HF and HF-LC-LP groups were 50,100 and 100 mg/kg,respectively.The contents of calcium and protein in HF-LC-LP group were half of MF and HF groups.Six months after treatment with fluoride,eight rats of each group were put to death with femoral artery bleeding.The rest 16 rats of each fluorosis group were divided into two groups,one was the control group and the other was fed with both fluorine and the compound Chinese medicine which simulated the actual situation of fluorosis area.Each rat of the treatment group was given the medicine 194 mg/100 g for six days every week.Daily urine samples were collected when the medicine had been used for 0,30 and 60 days.All the rats were put to death with femoral artery bleeding after the medicine had beengiven for 90 days,and limbs bones were dissected.Urine fluoride was tested by the method of fluoride ion selective electrode ; bone fluoride was tested by the method of high temperature ashing-fluoride ion selective electrode; bone mineral density(BMD),tissue mineral density(TMD),structure model index (SMI),trabecular thickness (Tb.Th),trabecular separation (Tb.Sp),anisotropy (a1/a3),trabecular connection density(Conn.D),the volume ratio of trabecular and bone tissue,the ratio of bone surface area and volume(BS/BV),and trabecular number(Tb.N) were detected by Micro-CT technology.Results The level of urinary fluoride of high fluoride and low calcium low protein treatment group [(11.01 ± 3.67)mg/L] was lower than that of its control group [(34.32 ± 9.50)mg/L,t =3.13,P ＜ 0.05] when rats were remedied with the compound Chinese medicine for 60 days.The level of bone fluoride of high fluoride treatment group[(275.38 ± 171.65)mg/kg] was lower than that of its control group[(701.67 ± 178.16)mg/kg,t =5.42,P ＜ 0.05] when rats were remedied withy the compound Chinese medicine for 90 days; bone fluoride of high fluoride and low calcium low protein treatment group[(313.26 ± 124.51)mg/kg] was lower than that of its control group[(794.66 ± 261.35)mg/kg,t =3.25,P ＜ 0.05].The differences of Tb.Th,Tb.Sp,a1/a3,Conn.D,BV/TV,BS/BV and Tb.N among groups were statistically significant(F =2.785,2.681,3.039,27.231,2.595,2.854,5.050,all P ＜ 0.05).Tb.Th[(0.04 ±0.01)mm] and Tb.Sp[(0.03 ± 0.01)mm] of middle fluorine treatment group were higher than those of their control groups[(0.02 ± 0.00),(0.02 ± 0.00)mm,all P＜ 0.05]; al/a3,Corm.D,BV/TV and Tb.N[(0.77 ±0.61),(510.91 ± 304.99)mm-3,(0.42 ± 0.06) and (13.58 ± 2.48)mm-1] were lower than those of their control groups[(1.11 ± 0.01),(2 403.69 ± 124.02)mm-3,(0.46 ± 0.03) and (18.12 ± 0.69)mm-1,all P ＜ 0.05].BV/TV(0.44 ± 0.04) of high fluoride treatment group were lower than those of their control groups(0.49 ± 0.00,P ＜ 0.05) ; Tb.Th[(0.04 ± 0.01) mm] was higher than that of its control group [(0.03 ± 0.00)mm,P ＜ 0.05].Conclusion The compound Chinese medicine may has therapeutic effect on rat skeletal fluorosis.
ABSTRACT
Objective To discuss the effect of different methods of dropping the high temperature of the tubercular meningitis patients. Methods 35 cases with tubercular meningitis with high fever were divided into research group(11 cases) and control group(24 cases) ,24 patients in control group were treated by traditional cooling method, 11 patients in research group were rteated by mild hypothermia therapy, The self signs, the intracranial pressure,Glasgow scores, complications and the death rates of patients were assessed and compared. Results The effective rates of the research and control cooling method were 81.8% and 41.7% respectively. The difference between the two groups was significant;After the intervention,compared with the control group, the self scale is superior in research group,and the intracranial pressure and the death rates of patients were lower,and patients'Glasgow scores were higher,but the complications between the two groups had no significant differences. Conclusion Mild hypothermia can effectively control patients'temperature,at the same time, which can improve the patients conscious state and reduce the mortality.
