Application of integrated theory of health behavior change in pelvic floor muscle exercise of patients with pelvic floor dysfunction after early cervical cancer surgery / 中国实用护理杂志

Objective:To explore the effect of nursing intervention based on the integration theory of health behavior change in pelvic floor muscle exercise of patients with pelvic floor dysfunction (PFD) after early cervical cancer surgery.Methods:A total of 134 patients with pelvic floor dysfunction after early cervical cancer surgery were selected and divided into test group ( n=67) and control group ( n=67) by random digits table method. The test group received three months of pelvic floor muscle exercise based on the theory of healthy behavior change. The control group received conventional pelvic floor rehabilitation care. The Pelvic Floor Distress Inventory-Short Form 20(PFDI-20), Pelvic Floor Impact Questionnaire-7(PFIQ-7), General Self-Efficacy Scale (GSES) and Social Support Rating Scale (SSRS) were evaluated before the intervention (T0), After one month of intervention (T1) and at the end of the intervention (T2). Results:The results of repeated measurement analysis of variance showed significant group/time interaction between PFDI-20 and PFIQ-7 scores ( Finteraction=29.196,13.213, both P<0.05); significant group/time interaction between GSES and SSRS scores ( Finteraction value was 25.664,70.240, both P<0.05). At the end of the intervention, the scores of PFDI-20 and PFIQ-7 in the test group were 66.54±14.04 and 73.20±7.41, which were lower than 77.47±15.91 and 78.39±8.51 in the control group over the same period. The difference was statistically significant ( t value was -4.216, -3.765, both P<0.01); the GSES and SSRS scores of the test group were 2.86±0.30 and 50.37±2.45, which were higher than the control group (2.51±0.34 and 46.42±2.82), the differences between the groups were statistically significant ( t value was 6.447, 8.662, both P<0.01). Conclusion:The nursing intervention plan based on the integration theory of health behavior change can significantly improve the self-efficacy, social support level and quality of life of patients with PFD after early cervical cancer surgery, and enhance the short-term and long-term pelvic floor rehabilitation effect of patients.

Prenatal diagnosis of absent pulmonary valve syndrome by fetal echocardiography: retrospective analysis of 12 cases / 中华围产医学杂志

Objective To summarize the echocardiographic features of fetal absent pulmonary valve syndrome (APVS).Methods Clinical data and echocardiograms of 12 cases of fetal APVS prenatally diagnosed in the Department of Pediatric Cardiology,Guangdong Cardiovascular Institute from July 2015 to April 2017 were reviewed retrospectively and the echocardiographic features of APVS were summarized.Results Aneurysmal dilation of the main pulmonary artery and branches arteries were found in all cases,causing tracheal and esophageal compression in one case and lung compression in two cases.Color Doppler revealed systolic and diastolic turbulent blood flow with "to-and-fro" blood flow in pulmonary arteries and pulmonary regurgitation.All fetuses were situs solitus and atrioventricular concordance.Eleven cases were also identified with malposition of the great arteries accompanied with ventricular septal defect,while the other one with normally related great arteries and intact ventricular septum was diagnosed with dysplasia of distal left pulmonary artery and pericardial effusion.Absent ductus arteriosus,increased cardiothoracic ratio and myocardial hypertrophy were found in four,two and five cases,respectively.Fetal umbilical arterial systolic/diastolic ratio and resistance index of all cases were normal.Conclusions Typical APVS is characterized by absent or rudimentary pulmonary valve accompanied with prominant dilated pulmonary arteries,pulmonary valve stenosis and severe pulmonary regurgitation.It is usually accompanied by conotruncal defects,but attention should also be paid to other atypical cardiac abnormalities during screening.

Research of gestrinone-related abnormal uterine bleeding and the intervention in the treatment:a multi-center, randomized, controlled clinical trial / 中华妇产科杂志

Objective To investigate the incidence, influencing factors and intervention of gestrinone-related abnormal uterine bleeding at different dosage of gestrinone in the clinical treatment. Methods This was a multicenter, randomized, control study of 195 Chinese women with endometriosis or adenomyosis from June 2011 to November 2013. The subjects were randomized into three groups with oral administration of gestrinone, 2.5 mg dose at one time;twice a week group:67 cases with oral administration twice a week last three months;double dose first month group:67 cases with oral administration triple times a week at first month, then twice a week for two months; three times a week group: 61 cases with oral administration three times a week last three months. The improvement of the abnormal uterine bleeding, the changes in estrogen, liver function and blood coagulation were evaluated. At the same time, B-ultrasound examination evaluation were performed. Results (1) Three months later, the incidence of abnormal uterine bleeding in twice a week group was 30%(20/67), in double dose first month group and three times a week group were 7%(5/67) and 16%(10/61) respectively, there were significant difference between three groups (P0.05). The body mass index significantly increased in three group (P0.05). As for blood coagulation, there were also no significant differences between the groups (P>0.05). Conclusions Double dose of gestrinone in the first month could significantly decrease the incidence of gestrinone-related abnormal uterine bleeding. It is a more optimied dosage of gestrinone and without severe side effects. Clinical trial registration Chinese Clinical Trial Registry, registration number: ChiCTR- TRC-12002327.

HOTAIR enhanced aggressive biological behaviors and induced radio-resistance via inhibiting p21 in cervical cancer.

We previously reported the frequent overexpression of HOX Antisense Intergenic RNA (HOTAIR) in human cervical cancer, which was significantly correlated with tumor progression and poor prognosis. In the present study, we investigated the detailed biological functions of HOTAIR in cervical cancer. In vitro, upregulation of HOTAIR inhibited apoptosis and promoted cellular proliferation, cell cycle progression, migration, and invasion; on the contrast, downregulation of HOTAIR induced more apoptosis, suppressed cellular proliferation, cell cycle, migration, and invasion. Moreover, a high level of HOTAIR was notably associated with radio-resistance and downregulation of p21 in the primary cultured cervical cancer cells. Further, we demonstrated that elevated HOTAIR could induce radio-resistance via inhibiting p21 in HeLa cells, while knockdown of HOTAIR upregulated p21 and consequentially increased the radio-sensitivity of C33A cells. Consistently, stable knockdown of HOTAIR significantly suppressed tumor growth and sensitized cervical cancer to radiotherapy in vivo. In conclusion, HOTAIR served as an onco-lncRNA in cervical cancer which could enhance various aggressive biological behaviors. Moreover, we proved that HOTAIR execute its functions mainly through inhibiting the p21 expression. These results proposed that targeting HOTAIR might be a potent therapeutic strategy in cervical cancer, especially for those patients who accepted radiotherapy.

MicroRNA-218 enhances the radiosensitivity of human cervical cancer via promoting radiation induced apoptosis.

We previously reported frequent loss of microRNA-218 (miR-218) in cervical cancer, which was associated with tumor progression and poor prognosis. As microRNAs were found invovled in the regulation of radiosensitivity in various human cancers, we therefore aim to investigate the effects of miR-218 on radiosensitivity of cervical cancer in the present study. The clonogenic survival assay demonstrated that loss of miR-218 could predict radioresistance in the primary cervical cancer cells (R(2)=0.6516, P<0.001). In vitro, abundant miR-218 increased the radiosensitivity in cervical cancer cells (P<0.001 for HeLa, P=0.009 for SiHa, P=0.016 for C33A and P=0.01 for CaSki). Upregulation of miR-218 significantly enhanced the radiation-induced apoptosis, which was further enhanced by the combination of miR-218 overexpression and radiation In xenograft growth assay, combination of miR-218 overexpression and radiation notably induced cellular apoptosis and suppressed tumor growth. In conclusion, we demonstrated that miR-218 resensitized cervical cancer cells to radiation via promoting cellular apoptosis. Moreover, we proved that miR-218 as a potent predictor of radiosensitivity in cervical cancer, especially for those patients with loss of miR-218.

Objective To discuss clinical effect and feasibility of laparoscopic pelvic lymphadendenectomy assisted radical vaginal hysterectomy (LARVH) in the treatment of cervical cancer. Methods Laparoscopic pelvic lymphadendenectomy assisted radical vaginal hysteretomy was performed in 38 patients with cervical cancer. The operative quality and postoperative recovery effects were analyzed. Results All 38 patients were successfully performed with LARVH and no complications. The radical vaginal hysteretomy were performed in all of patients, 21.4±2.2 pelvic lymph nodes were removed. The average duration of surgery was (240±25.6) min and the average hemorrhage was (340±40.2) ml. There were 7 patients who needed blood transfusion during operation. After operation, the mean time for passage of gas by anus was (2±0.26) days, and the mean recovery time of bladder function was (10.5±1.3) days. Patients were discharged after (9.2±1.1) days on average. 38 patients had no complication. Conclusions For the treatment of uterine neoplasm, LARVH decreased operative damage with more short recovery time, same operative extent as laparotomy. It is an ideal way to treat uterine neoplasm currently.
