Objective To explore the effect of strengthened health education in improving childbirth-related knowledge of puerperas during perinatal stage.Methods 100 cases of puerperas from December 2009 to January 2011 in department of gynaecology and obstetrics of our hospital were randomly divided into the control group and the observation group with 50 cases in each group.The control group received conventional health education,and the observation group was given strengthened health education.The childbirth-related knowledge,neonatal breast-feeding knowledge and the compliance and implementation of treatment and nursing before and 3d and 5d after education for the two groups were compared.Results The excellent and good rate of childbirth-related knowledge and neonatal breast-feeding knowledge for the observation group was significantly higher than the control group.The rate of compliance and implementation of treatment and care was higher than the control group.Conclusions The effect of strengthened health education in improving childbirth-related knowledge of puerperas during perinatal stage is significant.It also has a positive effect to improve compliance and results of treatment and nursing.

Objective To examine the effect of labouring in water on analgesia of vaginal delivery.Methods From June 2009 to February 2011,38 women who had volunteered to deliver in water in the obstetrical department were set as the observation group,another 70 women who chose vaginal delivery were named as the control group in the corresponding period.The items of labor pain,satisfaction with the birth experience,length of labor and neonatal outcomes were compared.Results The pain level of the observation group after labouring in water decreased compared with that before immersion in water.The delivery course was not influenced with a high rate of vaginal delivery.Conclusions Labouring in water can alleviate delivery pain,increase rate of vaginal delivery with no influence on delivery course and outcome of mothers and infants.It is a safe and effective analgesia method which should be widely applied.

Objective To investigate the effect of interleukin-1β (IL-1β) on the expression of synaptic protein SNAP-25 in the hippocampus in septic neonatal rat induced by systemic lipopolysaceharide (LPS) injection.Methods Sprague-Dawley (SD) rats were randomly divided into two groups:control group and sepsis group.The rat model of sepsis was produced by intraperitoneal injection of 1 mg/kg LPS,and rats in the control group were injected with an equal volume of 0.01 mol/L phosphate buffered saline (PBS).The expression levels of IL-1β and IL-1R1 in the hippocampus at 1,2 and 3 d,and synaptosomal-associated protein 25 (SNAP-25) at 7,14 and 24 d after LPS intraperitoneal injection were detected by Western blot.After cultured for 24 h,primary hippocampal neurons were divided into four groups including the control group,IL-1β (40 ng/mL) treatment group,IL-1β (40 ng/mL) + IL-1Ra (40 ng/mL) treatment group,and IL-1Ra (40 ng/mL) treatment group.The effect of IL-1β on SNAP-25 expression in primary hippocampal neuron was determined by Western blot and real-time PCR.The purity of hippocampal neurons were identified by NeuN immunofluorescence staining and the activity of neurons were detected by CCK-8 assay.All data were analyzed by SPSS version 22.0.The data were analyzed by student-t test and Dunnett-t test.The interaction effects were analyzed by factorial ANOVA.Differences were considered to be statistically significant if P＜ 0.05.Results Compared with the control group,the expressions of IL-1β and IL-1R1 were significantly increased in the hippocampus at 1,2 and 3 d after intraperitoneal injection of LPS (P＜0.05).The expression of SNAP-25 protein was decreased at 7,14,and 28 d after intraperitoneal injection of LPS (P＜0.05).The purity of primary neurons was about up to 92％.The activity of primary neurons was not relatively changed after treated with IL-1β at a dose less than 40 ng/mL.The level of SNAP-25 protein was obviously decreased in primary neurons at 24 h after IL-1β treatment (P＜0.05).IL-1Ra treatment might reverse the effect of IL-1β on primary neurons (P＜0.05).While,the expression of SNAP-25 mRNA was not statistically different in each group (P＞0.05).Conclusions IL-1β may possibly inhibit the expression level of SNAP-25 protein in the hippocampus in the septic rats through its receptor IL-1R1,which would contribute to cognitive dysfunction of septic neonatal rats in later life.

Objective:To perform two-step clustering analysis based on urodynamics in patients with neurogenic bladder (NB) and exploring characteristics affecting success rate of sacral neuromodulation (SNM).Methods:The data of 174 NB patients who received SNM therapy in our hospital from September 2018 to August 2023, were retrospectively analysed. There were 94 males and 80 females, with average age of (50.4±17.9)years, median duration of 2 (1, 3)years, and body mass index of 21.5 (20, 25) kg/m 2. Among them, 50 patients had chronic diseases (hypertension or diabetes). Additionally, 77 patients (44.3%) presented with voiding symptoms, 47 patients (27.0%) with storage symptoms, and 50 patients (28.7%) with mixed symptoms. The etiologies included spinal cord lesions in 110 patients (63.2%), brain lesions in 21 patients (12.1%), peripheral nerve lesions in 36 patients (20.7%), and other causes in 7 patients (4.0%). All patients underwent urodynamics and SNM phase 1 test. If patient's subjective symptoms or objective indicators improved > 50%, it is defined as treatment success and feasible to received second stage of SNM. The success rate was analyzed. Clinical indicators and urodynamic parameter were collected for exploring the difference of the above indicators between two groups (with or without conversion). The 174 patients were grouped using two-step clustering analysis, dividing them into two groups. The differences in clinical data, urodynamic parameters, and the conversion rate of SNM phase II between the two groups were compared. Results:Among these patients, 126 (72%) underwent the second stage of SNM. Compared with the non-conversion group, patients in the conversion group exhibited the following characteristics: high proportion of female[51.6% (65/126) vs. 31.2% (15/48)], younger[(48.1± 18.3)year vs. (56.4±15.4) year], lower proportion of history of chronic disease[23.9% (30/126) vs. 41.7% (20/48)], storage predominant symptoms predominant[33.3% (42/126) vs. 10.4% (5/48)], sensitive bladder sensation[50.0% (63/126) vs. 11.1% (14/48)], normal detrusor contractility [26.2% (33/126) vs. 10.4% (5/48)] and detrusor-sphincter dyssynergia [21.4% (27/126) vs. 4.2% (2/48)]and lower post-void residual [105.5(49.3, 231.3) ml vs. 197.9(114.8, 284.8) ml], ( P<0.05). After excluding multicollinearity, patients were divided into two group mainly based on coordination, detrusor stability, and detrusor contractility through two-step clustering analysis: 98 patients in Group 1 and 76 patients in Group 2. The success rate was higher in Group 2 [82.9% (63/76) vs. 64.3% (63/98), P=0.006]. Compared with Group 1, Group 2 exhibited the following characteristics: higher proportion of storage symptoms [43.4% (33/76) vs. 14.3% (14/98)], sensitive bladder sensation [67.1% (51/76) vs. 26.5% (26/98)], detrusor overactivity [46.1% (35/76) vs. 3.1% (3/98)], normal detrusor contractility [43.4% (33/76) vs. 5.1% (5/98)], and detrusor-sphincter dyssynergia [38.2% (29/76) vs. 0] ( P all<0.05). Additionally, group 2 had lower post-void residual [69.0 (23.8, 136.6) ml and 197.9 (123.2, 287.4) ml] and smaller bladder capacity [(281.9±144.9) ml vs. (430.4±176.7) ml] ( P all<0.01). Conclusions:Patients with storage symptoms, low post-void residual, sensitive bladder sensation, detrusor overactivity, normal contractility, or detrusor-sphincter dyssynergia indicate a higher conversion rate to second stage, making them more suitable for SNM testing.

Objective:To investigate the effect of melatonin on oligodendrocyte maturation and differentiation in corpus callosum of septic neonatal rats induced by systemic lipopolysaccharide (LPS) injection.Methods:Sprague-Dawley rats were randomly allocated into the control group, septic experimental group, and melatonin group. In the septic experimental group, rats were intraperitoneally administrated with lipopolysaccharide (LPS) (1 mg/kg). In the melatonin group, melatonin was intraperitoneally administered (10 mg/kg) at 0.5 h after LPS injection. The expression level of IL-6, olig1, olig2, and the MAG protein were detected by Western blot at different time points in the three groups. BV-2 cells were used in vitro. For drug administration, the effect of LPS, melatonin and melatonin receptor antagonist, luzindole, on IL-6 expression in BV-2 microglia cell was determined by Western blot. The medium of BV2 cell were collected to treat primary OPCs. The expression level of olig1, olig2 and MAG protein in primary OPCs were detected by Western blot. SPSS 20.0 statistical software was used for analysis, and the data were analyzed by one-way ANOVA and two-way ANOVA. Differences were considered to be statistically significantly if P<0.05. Result:Compared with the LPS group, the expression of IL-6 was significantly decreased in the corpus callosum at 6 h, l d, and 3 d in the melatonin group ( P<0.05). The expression of olig1, olig2 and MAG protein were increased at day 7, 14, and 28 in the melatonin group compared with the LPS group ( P<0.05). In vitro the expressions of IL-6 was significantly increased after LPS treatment ( P<0.05), but was decreased in the LPS+melatonin treatment group ( P<0.05). After treatment with melatonin receptor inhibitor, luzindole, the expressions level of IL-6 was increased ( P<0.05). The expression of olig1, olig2 and MAG protein were decreased with conditioned medium in the LPS BV2 cell group than the control group in the primary OPCs ( P<0.05). However, those were increased with conditioned medium in the LPS+melatonin BV2 cell group than the LPS group ( P<0.05). Conclusions:Melatonin may inhibit the inflammation response in the corpus callosum through its receptor, and may promote the maturation and differentiation of oligodendrocyte, suggesting that melatonin may have therapeutic effect on neuroinflammation and axonal hypomyelination on PWM in septic neonatal rats.

Purpose: Neuroendocrine prostate cancer (NEPC) represents a particularly aggressive subtype of prostate cancer with a challenging prognosis. The purpose of this investigation is to craft and confirm the reliability of nomograms that can accurately forecast the 1-, 3-, and 5-year overall survival (OS) and cancer-specific survival (CSS) rates for individuals afflicted with NEPC. Materials and Methods: Data pertaining to patients diagnosed with NEPC within the timeframe of 2010 to 2020 was meticulously gathered and examined from the Surveillance, Epidemiology, and End Results Program (SEER). To predict OS and CSS, we devised and authenticated two distinct nomograms, utilizing predictive variables pinpointed through both univariate and multivariate Cox regression analyses. Results: The study encompassed 393 of NEPC patients, who were systematically divided into training and validation cohorts at a 2:1 ratio. Key prognostic factors were isolated, verified, and integrated into the respective nomograms for OS and CSS. The performance metrics, denoted by C-indices, stood at 0.730, 0.735 for the training set, and 0.784, 0.756 for the validation set. The precision and clinical relevance of the nomograms were further corroborated by the analysis of receiver operating characteristic curves, calibration plots, and decision curve analyses. Conclusions The constructed nomograms have demonstrated impressive efficacy in forecasting the 1-, 3-, and 5-year OS and rates for patients with NEPC. Implementing these predictive tools in clinical settings is anticipated to considerably enhance the care and treatment planning for individuals diagnosed with this aggressive form of prostate cancer, thus providing tailored and more precise prognostic assessments.
