This study was to investigate the diagnosis value of simplified uredynsmic test in stress urinary incontinence. Fifty patients with stress test-confirmed urine incontinence underwent simplified urodynamic test before routine urodynamic test. Detrusor instability, max bladder volume, average flow rate, and residual urine of simple urodynamic test were compared. Simplified urodynamic test showed a sensitivity of 87%, specificity of 9/12, positive predictive value of 92%, and negative predictive value of 9/14. There was no significant difference in max bladder volume, average flow rate, and residual urine between the two tests. Simplified urodynamic test might be a reliable method for diagnosis of stress urinary incontinence, and could be used for detrnsor instability screening.

Objective To explore the effect of continuing nursing mode in women with stress urinary incontinence who accept the pelvic floor functional exercise at home.Methods By convenient sampling method, 60 patients with incontinence were selected, who received four weeks pelvic floor electrophysiological treatment and biofeedback treatment in Peking Union Medical College Hospital, and then received 12 weeks of pelvic floor rehabilitation therapy at home . All patients were divided into control group and observation group on average. The patients of the control group underwent routine health education, while the patients of the observation group were given pelvic floor muscle tissue by electrical stimulation and the continuation of nursing mode, then we compared two groups of maternal pelvic floor functional exercise adherence, 1 hours urine pad test for lateral leakage urine volume, ICI-Q-SF score for subjective improvement.Results After interventions, the excise compliance of pelvic floor muscle was better in the observation group than that of the control group (P<0.05); 3 and 6 months after intervention, the lateral leakage urine volumes were both decreased in two groups (P<0.05); both scores of ICI-Q-SF in two groups were improved, but that of the observation group was more obvious (P<0.05).Conclusions Planned continuing nursing mode can maintain and strengthen the clinical treatment of urinary incontinence, and increase the compliance of pelvic floor muscle function exercise in patients with urinary incontinence.

Objective:
This study aims to explore the relationships of family functioning, general well-being, and exercise with psychological distress.Furthermore, we investigated the special roles of general well-being and exercise on the association between family functioningand psychological distress.
Methods:
Of 769 end-stage renal disease (ESRD) patients participated in the cross-sectional study which consisted of the 12-item GeneralHealth Questionnaire (GHQ-12), the Family APGAR Scales, and the General Well-Being Schedule. The collected data were analyzedusing multiple linear regression analysis and path analysis.
Results:
The prevalence of psychological distress was 72.3%. Family functioning, general well-being and exercise were associated factorsof psychological distress (p<0.05). The indirect effect of family functioning on psychological distress was partially mediated by generalwell-being (Effect=-0.08, 95% CI=-0.11, -0.04). In addition, the effect of family functioning on general well-being was moderated byexercise (Index=-0.092, SE=0.033, 95% CI=-0.159, -0.029).
Conclusion
The prevalence of psychological distress among ESRD patients was high. Family functioning, general well-being and exercisewere associated with psychological distress. Family functioning could affect psychological distress partially by affecting general wellbeing.Furthermore, exercise had a significant moderating effect on the relationship between family functioning and general well-being.Psychiatry Investig 2020;17(4):356-365

OBJECTIVETo assess the association of four single nucleotide polymorphisms (SNPs) (rs12190359C>T, rs562047C>G, rs1008438G>T, and rs1043618G>C) of HSPA1A gene with the development of cervical cancer among ethnic Han Chinese from Yunnan.
METHODSOne hundred and thirty patients with CIN III, 444 patients with cervical cancer, and 548 healthy individuals were recruited, and the genotypes of the above SNPs were determined with a Taqman assay. Haplotypes were constructed, and their association with the development of cervical cancer was analyzed.
RESULTSThe frequencies of G and T alleles of rs1008438G>T were significant different between the CIN III and control groups, as well as between the cancer and control groups (P=0.022 and P=0.030, respectively). There was a significant difference in genotypic frequency of rs1008438G>T between the CIN III and control groups (P=0.047). The allelic and genotypic frequencies of rs12190359C>T, rs562047C>G, and rs1043618G>C did not significantly differ between the CIN III, cervical cancer and control groups (P> 0.05). The frequencies of haplotypes formed by rs562047C>G, rs1008438G>T and rs1043618G>C also did not significantly differ between the CIN III, cancer and control groups (P> 0.05).
CONCLUSIONThe G allele of rs1008438G>T may be a protective factor for cervical cancer among ethnic Han Chinese from Yunnan.
