RESUMO

AIMS: A pilot survey shows that primary nocturnal enuresis (PNE) prevalence has increased significantly during the past decade in Mainland China. Whether it is related to the delay of elimination communication (EC) is unclear. This study retrospectively investigated the influence of delayed EC on the PNE prevalence in children and adolescents in mainland China. METHODS: A cross-sectional study of PNE prevalence was performed by distributing 19 500 anonymous self-administered questionnaires to parents in five provinces of mainland China from July 2017 to October 2017. The questionnaires included sociodemographic data, family caregivers' information, and details about the disposable diapers (DD) usage, EC commencement date, psychological disorders, lower urinary tract symptoms, and family history of PNE in children and adolescents. The 2017 PNE prevalence was compared with that of 2006 in Mainland China. RESULTS: The total response rate was 97.04% (18 631 of 19 500) and 92.39% (18 016 of 19 500) qualified for statistical analysis. The PNE prevalence in 2017 has increased significantly compared to that of 2006 (7.30% vs 4.07%, P < 0.001). The PNE prevalence in children with EC starting before 6 months of age was significantly lower than those who start after 12 months of age. The longer DD were used and the later the beginning of EC, the higher the PNE prevalence was found. CONCLUSIONS: The PNE prevalence in Mainland China has increased significantly during the past 10 years. A longer use of DD and later onset of EC may be risk factors for PNE.

RESUMO

AIMS: To explore the risk factors of nocturia in Chinese inhabitants aged ≥40 years. METHODS: A randomized, community-based, cross-sectional study was performed on 10,160 inhabitants ≥40 years old in mainland China, via a stratified sampling approach. A questionnaire, including socio-demographics, lifestyle factors and medical history, was completed. Nocturia was defined as a threshold of two or more voids per night. Differences in prevalence between age and gender groups were ascertained by the chi-squared test. Gender-related factors were evaluated by multivariate logistic regression analysis. P < 0.05 was considered to be statistically significant. RESULTS: Data on 9,637 (94.9%) people aged 59.6 ± 9.7 years qualified for final statistical analysis. The overall prevalence of nocturia was 31.7% (3,053/9,637), and this increased with age (P < 0.001). Nocturia was significantly associated with cardiovascular disease and overactive bladder symptom score (OABSS) (P < 0.05), while sporting activities were protective (P < 0.001). Diabetes mellitus (DM) was significantly correlated with nocturia in men (P < 0.05), whereas hypertension was correlated with nocturia in women (P < 0.05). No correlation was found between nocturia and education level, occupation, civil status, tea consumption, body mass index (BMI), female birth history, and International Prostate Symptom Score. CONCLUSIONS: In Chinese people aged ≥40 years, nocturia is associated with aging, OABSS, cardiovascular disease, hypertension, and DM. Sporting activities are negatively associated with nocturia.

RESUMO

We performed a retrospective, case-control study to evaluate whether the urine flow acceleration (UFA, mL/s(2)) is superior to maximum uroflow (Qmax, mL/s) in diagnosing bladder outlet obstruction (BOO) in patients with benign prostatic hyperplasia (BPH). In this study, a total of 50 men with BPH (age: 58±12.5 years) and 50 controls (age: 59±13.0 years) were included. A pressure-flow study was used to determine the presence of BOO according to the recommendations of Incontinence Control Society (ICS). The results showed that the UFA and Qmax in BPH group were much lower than those in the control group [(2.05±0.85) vs. (4.60±1.25) mL/s(2) and (8.50±1.05) vs. (13.00±3.35) mL/s] (P<0.001). According to the criteria (UFA<2.05 mL/s(2), Qmax<10 mL/s), the sensitivity and specificity of UFA vs. Qmax in diagnosing BOO were 88%, 75% vs. 81%, 63%. UFA vs. Omax, when compared with the results of P-Q chart (the kappa values in corresponding analysis), was 0.55 vs. 0.35. The prostate volume, post void residual and detrusor pressure at Qmax between the two groups were 28.6±9.8 vs. 24.2±7.6 mL, 60.4±1.4 vs. 21.3±2.5 mL and 56.6±8.3 vs. 21.7±6.1 cmH2O, respectively (P<0.05). It was concluded that the UFA is a useful urodynamic parameter, and is superior to Qmax in diagnosing BOO in patients with BPH.

RESUMO

OBJECTIVE: The purpose of this study was to investigate the effect of Egr2 and Egr4 upregulation on ischemic stroke recovery of rats. METHODS: In this study, Sprague Dawley (SD) rats assigned at random into control, sham and MCAO (middle cerebral artery occlusion) group were treated accordingly to build MCAO models. The neurological severity scores (NSS) test was applied to assess rats' behavior. Triphenyltetrazolium chloride (TTC) staining reflected infarct areas while Nissl staining revealed the number of neurons. Levels of pro-inflammatory cytokines (interleukin [IL]-1ß, IL-6 and tumor necrosis factor [TNF]-α) were judged by enzyme-linked immunosorbent assay (ELISA) in brain and serum tissues. We applied western blot to check the expression of Egr2, Egr4 and JNK/c-JUN (c-Jun N-terminal kinase) pathway. Further grouping of rats were based on various transfection, requiring control, sham, MCAO, MCAO + Egr2 cDNA (complementary DNA), MCAO + Egr4 cDNA, MCAO + Egr2 cDNA + Egr4 cDNA group to observe difference in MCAO recovery and JNK/c-JUN-pathway-related protein expression. RESULTS: Under successful modeling of MCAO, western blot results suggested down-regulation of Egr2 and Egr4 and overexpression of pro-inflammatory cytokines. The JNK/c-JUN pathway was activated. On upregulation of Egr2 and Egr4 in infarct areas, neurological function of SD rats recovered along with repressed JNK/c-JUN pathway activation and increased neuron number. CONCLUSION: Upregulation of Egr2 and Egr4 could demote the activation of JNK/c-JUN pathway and the expression of pro-inflammatory cytokines in MCAO rats, so that Egr2 and Egr4 might be potential targets for ischemic stroke in future.

RESUMO

PURPOSE: To investigate the prevalence of spina bifida occulta (SBO) and its relationship with the presence of overactive bladder (OAB) in middle-aged and elderly people in China. METHODS: A cross-sectional community-based survey was carried out at 7 communities in Zhengzhou City, China from December 15, 2013 to June 10, 2014, where residents aged over 40 years were randomly selected to participate. All of the participants underwent lumbosacral radiographic analysis and relevant laboratory tests. A questionnaire including basic information, past medical history and present illness, and the OAB symptom score was filled out by all participants. Chi-square tests and logistic regression were used for data analysis with a P-value of <0.05 denoting statistical significance. RESULTS: A total of 1,061 subjects were qualified for the final statistical analysis (58.8±11.7 years; male, 471 [44.4%]; female, 590 [55.6%]). The overall prevalence of SBO was 15.1% (160 of 1,061): 18.3% (86 of 471) in men and 12.5% (74 of 590) in women. Among these subjects, 13.7% (145 of 1,061) had OAB: 13.2% (62 of 471) in men and 14.1% (83 of 590) in women. The results of logistic regression showed that age, SBO, history of cerebral infarction (HCI), and constipation were risk factors for OAB (P<0.05), while sex, history of childhood enuresis (HCE), body mass index (BMI), and diabetes mellitus (DM) were not (P>0.05). In men, age, SBO, and constipation were risk factors for OAB (P<0.05), while HCE, BMI, DM, HCI, and benign prostate hyperplasia were not (P>0.05). In women, age, SBO, and HCI were risk factors for OAB (P<0.05), while HCE, BMI, DM, vaginal delivery, and constipation were not (P>0.05). CONCLUSIONS: The prevalence of SBO is high and it is related to OAB in middle-aged and elderly people in China.
