ABSTRACT
Objective:To investigate the application of Folly urethral catheter in transvastatal resection of adhesion (TCRA) and its preventive effect on prevention of re-adhesion.Methods:A total of 78 patients with intrauterine adhesions admitted to the Department of gynecology and obstetrics of the Maternal and Child Health Care Hospital Affiliated to Anhui Medical University from March 2018 to March 2019 were selected as the study objects.The prospective study was conducted and divided into two groups according to the computer random number method.In the control group, 39 cases were treated by TCRA combined with intrauterine placement of contraceptive ring, while in the observation group, 39 cases were treated by hysteroscopic adhesion separation operation combined with Folly catheter placement.The curative effect, intrauterine adhesions, menstrual improvement score, recurrence and pregnancy were compared before and 6 months after operation.Results:The total effective rate of the observation group was 94.87% (37/39), and that of the control group was 79.49% (31/39), The difference between the two groups was statistically significant (χ 2=4.129, P<0.05). The score of intrauterine adhesions was (22.14±2.57) in the control group and (1.76±0.87) in the observation group, and (23.05±3.08), (1.81±0.60) in the observation group, there was no significant difference between the two groups( t=1.417, 0.295; all P>0.05). At 3 months after operation, the scores of intrauterine adhesions and menstrual states in the control group were (17.63±2.88) and (1.07±0.38), respectively, and those in the observation group were (14.27±3.52) and (0.53±0.21), the difference between the two groups was statistically significant( t=4.614, 7.767, all P<0.001). There were significant differences in the scores of intrauterine adhesions and menstrual state before and after operation in the observation group ( t=7.297, 4.539, all P<0.001). There were significant differences in the scores of intrauterine adhesions and menstrual states before and after operation in the observation group ( t=11.723, 12.575, all P<0.001). The recurrence rate was 23.08% (9/39) in the observation group and 46.15% (18/39) in the control group at 6 months after operation.The difference was statistically significant ( P=0.032). The pregnancy rate of the observation group was observed.12.82% (5/39), 7.69% (3/39) in the control group, the difference was not statistically significant( P=0.455). Conclusion:Hysteroscopic adhesion separation combined with Folly catheter placement for the treatment of intrauterine adhesions can significantly improve the short-term efficacy, prevent re-adhesion, and better regulate the menstrual cycle.
ABSTRACT
Objective To compare the hemostatic efficacies of radial artery balloon and spinning hemostat in elderly patients after radial artery intervention.Methods Eighty elderly patients undergoing transradial coronary intervention were randomly divided into balloon and spinning hemostat groups,with 40 cases in each group.After operation,balloons and spinning hemostats were used for hemostasis,respectively.The two groups were compared in terms of hemostatic effect,comfort degree and incidence of complications.Results These was no difference in hemostatic effect between the two groups(P>0.05).The balloon hemostat group was better than the spinning hemostat in respect of comfort degree.The incidences of ischemia and vagal reflex in the balloon hemostat group were significantly lower than the spinning hemostat group(P<0.05).Conclusion The balloon hemostat for radial artery intervention is more suitable for elderly patients undergoing oral treatment.
ABSTRACT
AIM:To observe the antineoplastic effect of Naja Naja atra venom (NNAV) on S180 bearing mice and to study the possible antineoplastic mechanism. METHODS:We observed the effect of NNAV on tumor weight、plasma nitric oxide content、plasma endothelin content and spleen index in S180 bearing mice with different concentration and different period by means of injecting into abdomen. RESULTS:Treatment with NNAV solution of different concentration could markedly inhibit S180 growth (especially in the low concentration group and by long period) and rate of inhibiting ranged from 21 63% to 49.25%; the plasma nitric oxide content, the plasma endothelin content and NO/ET ratio in tumor bearing mice were obviously higher than those of the normal control group, while after treatment with NNAV solution, the plasma nitric oxide level, the plasma endothelin level and NO/ET ratio could be reduced markedly, and it was noticed that NO/ET ratio in the group with highest inhibiting rate was most close to that of the normal control group. The spleen index was obviously increased after treatment with NNAV solution.CONCLUSION:The antineoplastic effect of NNAV on S180 bearing mice is best in long period by means of injecting into abdomen with low concentration. The mechanism of the antineoplastic effect of NNAV may be related to lowering the plasma nitric oxide and endothelin level, regulating the NO/ET ratio and enhancing the immune response.
