Objective To analyze the effect and application value of continuation nursing in the management of pelvic organ prolapse (POP) patients. Methods From June 2016 to December 2017, 50 patients with POP who were treated with pessary were randomly divided into study group and control group by randomized comparison digital table. The study group was followed by family continuation care. The nursing guidance was compared at the time of enrollment, 3 months and 6 months after enrollment, and the difference between the two groups in terms of disease awareness, daily behavioral ability, psychological state and complications were compared. Results The study group was significantly better than the control group in terms of disease awareness, daily behavioral ability, psychological state and satisfaction rate of nursing services (t=13.2667-19.8533,χ2=0.12-4.56, P<0.05). Conclusion The application of pessary in the treatment of POP patients in the home management can be used to reduce complications and improve the quality of life of patients. It has application and promotion value.

Objective To find out a method that is simple and reliable for screening phenylketonuria(PKU) heterzygotes.Methods Detecting and analyzing plasma phenylalanine(Phe) and tyrosine(Tyr) from 101 known-PKU heterozygotes and 2023 married people by means of a high performance liquid chromatograph.Results Significant differences were observed between known-PKU heterozygotes and screening population in plasma Phe, Phe/Tyr and Phe2/Tyr. The values of plasma Phe, Phe/Tyr and Phe2/Tyr from 94.1% known-PKU heterozygotes were higher than +2s of those values from screening population. According to the limits of +2s,81 cases were screened out from the 2023 married people. It was the first time to get the actual heterozygote frequency of 4% from population.Conculsion The biochemical method mentioned above is available for use in screening PKU heterozygotes.

Objective To explore the value of three-dimensional ultrasonic technique in precise pelvic floor reparation. Methods One hundred and twenty-six patients with Ⅱ - Ⅳ degree pelvic organ prolapse were selected. The patients were divided into traditional group (57 cases, transvaginal hysterectomy and vaginal wall reparation) and study group (69 cases, transvaginal hysterectomy and vaginal wall reparation combined with indication of transvaginal three-dimensional ultrasound). The changes of perioperative indexes and postoperative recurrence rate were compared between 2 groups. Results There were no statistical differences in surgery time, intraoperative blood loss, retention catheterization time postoperative exhaust and defecation time duration in hospital and postoperative complication between 2 groups (P＞0.05). The subjective and objective cure rate 3 months after operation in both groups was 100.0% ; there were no statistical differences 6 months after operation between 2 groups (P＞0.05). The objective cure rates 12 and 24 months after operation in study group were significantly higher than those in traditional group: 20.0% (11/55) vs. 7.5% (5/67) and 27.3% (15/55) vs. 11.9% (8/67), and there were statistical differences (P＜0.05). Conclusions The recurrence rate of precise traditional pelvic floor reparation with the guidance of transvaginal three-dimensional ultrasound is significantly lower than that of traditional pelvic floor reparation.

Objective To explore the therapeutic effect and clinical significance of pelvic floor rehabilitation technique in female with myofascial chronic pelvic pain (MCPP) by detecting the pressure pain thresholds (PPTs). Methods One hundred healthy female (control group) and 324 female MCPP patients (observation group) from January 2009 to December 2016 were selected. Automatic body surface and vaginal pressure pain detector was applied to detect two groups′PPTs of the 34 spots. The difference of PPTs at each spot was analyzed in two groups. In addition, 51 patients with moderate and severe MCPP were selected to record the changes of PPTs and pain scores before and after the treatment of pelvic floor rehabilitation technique. Results The average PPTs of the abdomen, vulva, pelvic floor and vaginal front and back fornix, bilateral adnexa uteri and sacrouterine ligament in the observation group were significantly lower than those in the control group (P<0.01 or<0.05). The average PPTs of the abdomen, vulva, pelvic floor muscles and vaginal front and back fornix, bilateral adnexa uteri and sacrouterine ligament of 51 MCPP patients after treatment were significantly higher than those before treatment (P<0.01). After treatment, PPTs and pain scores of the pelvic floor muscles, bilateral adnexa uteri, bilateral sacrouterine ligament, bilateral sacral spine ligament and vaginal front and back fornix were negatively correlated (r =- 0.78 to- 0.19, P = 0.01 to 0.04); there was a negative correlation between the PPTs and pain scores of the left and right latissimus dorsi (r=-0.28, P=0.04;r=-0.32, P=0.02). The complete remission rate with the pelvic floor rehabilitation technique in 51 patients with MCPP was 9.8％(5/51), the significant remission rate was 90.2％(46/51), and the total remission rate was 100.0％ (51/51). Conclusions Compared with the normal healthy ones, female with MCPP has lower PPTs in the abdomen, perineum, vagina and pelvic floor. The effect of pelvic floor rehabilitation technique on MCPP is well, which can increase patients′PPTs to reduce pain scores. It is a worthwhile method to treat these diseases.

Objective:To compare the changes in pelvic floor electrophysiology and imaging in female patients with myofascial pelvic pain (MFPP), and to explore the characteristics and significance of these changes.Methods:A total of 49 MFPP patients who were admitted to the of Dalian Women′s and Children′s Medical Center (Group) from January 2019 to October 2021 were randomly selected as the research group, and 41 healthy women during the same period were selected as the control group. Both groups filled in the center′s medical history and general condition survey form. French PHENIX series pelvic floor muscle potential detection instrument was used to detect the resting vaginal muscle potential and maximum muscle potential of the two groups. The static tension, dynamic tension and pelvic floor muscle contraction force of the two groups were measured by French PHENIX series electronic tensioning apparatus with 5° and 10° opening respectively. Two dimensional transperineal ultrasound and three dimensional transvaginal ultrasound produced by B-K Company in Denmark were used to measure the length between the lower margin of the bladder neck from the symphysis pubis and the bladder neck and the bladder bottom (BND, BSD), the diameter of the genital tract hiatus and the angle of the anus and rectum. The area, anterior-posterior diameter, transverse diameter and different damage degrees of levator ani levator were measured.Results:The resting muscle potential of the study group was higher than that of the control group: 2 μV vs. 1 μV ( P<0.05); the maximum vaginal myopotential was higher than that of the control group: 7 μV vs. 6 μV ( P<0.05). The static tension, dynamic tension and contractile force: 204 g/m 2 vs. 175 g/m 2, 450 g/m 2 vs. 410 g/m 2 and 237 g/m 2 vs. 51 g/m 2 of pelvic floor muscle in the study group were higher than those in the control group when the tensioner was opened for 5° ( P<0.05). In resting state, BND, BSD and reproductive tract hiatus diameter in the study group were smaller than those in the control group: 14.0 mm vs. 16.7 mm, 15.3 mm vs. 19.7 mm, 46.7 mm vs. 49.5 mm ( P<0.05). The anal angle was greater than that of the control group: 129° vs. 112° ( P<0.05). The anal right angle in the study group was greater than that in the control group: 113° vs. 109° ( P<0.05). In the resting state, the area of levator ANI hiatus: 10.1 cm 2 vs. 11.6 cm 2, anterior and posterior diameters: 44.2 mm vs. 47.4 mm, transverse diameters and the defect scores of levator ani in the study group were all smaller than those in the control group ( P<0.05). Conclusions:MFPP presents with persistent pelvic floor muscle spasm and loss of coordination. MFPP can be treated by spasmolysis of pelvic floor muscle and fascia, which provides reference value for clinical treatment.
