Objective:To develop a Pediatric Nursing Care Deficiency Scale (PNCDS) and evaluate its reliability and validity.Methods:Based on theories of nursing care deficiency and considering pediatric nursing characteristics, the scale was developed following standard procedures and principles. This included semi-structured interviews, expert evaluations, a pilot survey, and a large-scale survey to finalize the scale.Results:The final version of the PNCDS comprised four dimensions with 25 items. The content validity index (CVI) of the overall scale was 0.937, with item-level CVIs ranging from 0.857 to 1.000. Exploratory factor analysis revealed that the factor loadings for all items were greater than 0.5, and the four factors accounted for a cumulative variance of 66.456%. Confirmatory factor analysis indicated a good model fit for the final scale. The overall Cronbach's α coefficient for the scale was 0.917, while the Cronbach's α coefficients for the four dimensions were 0.861, 0.923, 0.881, and 0.909, respectively.Conclusions:The PNCDS demonstrated good reliability and validity and provides a useful tool for assessing pediatric nursing care deficiencies and aiding in the development of intervention strategies.

【Objective】 To monitor the positive rates of IgM and IgG antibodies and the changes in S/CO values over time in voluntary blood donors infected with SARS-CoV-2 after recovery, in order to provide theoretical basis and data support for ensuring clinical blood safety. 【Methods】 A total of 54 platelet donors who met the inclusion criteria were selected for this study, and 359 blood samples (plasma) from T1 to T7 (at 7 time points, spanning 14 to 15 weeks) were continuously monitored for SARS-CoV-2 IgM and IgG antibodies using fully automated chemi-luminescence method. 【Results】 Among 359 blood samples (plasma) from 54 donors, 349 were with valid test results.Eleven donors were tested positive for IgM, with a positive rate of 20.37%, and IgM antibody S/CO value gradually increased during T1-T3, but gradually decreased during T4-T7. Fifty-four donors were tested positive for IgG, with the positive rate of 100%, and the S/CO value of IgG antibody gradually decreased over time. During the period of T1 -T7, there was no significant difference in SARS-CoV-2 IgG antibody S/CO value between gender (male/female) or age group (18-39 years old /40-60 years old). 【Conclusion】 The positive rate of SARS-CoV-2 IgG antibody in platelet donors after recovery from SARS-CoV-2 infection was 100% during 2-14 weeks, and the IgG S/CO value gradually decreases over time. The long-term dynamic changes of SARS-CoV-2 serologically specific IgG and IgM antibodies in blood donors are worthy of further study.

Objective:To detect the abnormalities within the functional connectivity (FC) of the prefrontal cortex (PFC) in patients with overactive bladder (OAB) and to explore its central pathogenesis.Methods:Seven OAB patients (OAB group, 6 females, mean age 47.6±16.0 years) and 13 healthy controls [HC] (HC group, 10 females, mean age 49.9±9.2 years) were prospectively enrolled from August to December 2020. All subjects underwent rs-fNIRS scanning synchronized with urodynamic monitoring, and two rs-fNIRS scans were performed when the bladder was empty and when the desire to void was strong/urodynamic monitoring indicated detrusor hyperactivity (DO). The Pearson's correlation coefficients (r value, i. e., FC value) between time series of the 22 channels were calculated, and a 22×22 FC matrix for each subject was obtained. A paired-sample t-test ( P<0.05, FDR corrected) was used to compare the difference in FC values between the HC group and the OAB group when the bladder was empty and the desire to void was strong. A two-sample t-test ( P<0.05, FDR corrected) was used to compare the group differences in FC values between OAB and HC groups. Results:In this study, 7 patients were included in the OAB group, including 1 male and 6 female. The mean age was (47.6±16.0) years old. In HC group, 13 healthy subjects were included, including 3 males and 10 females. The mean age was (49.9±9.2) years. There was no significant difference in baseline data between the two groups, including age, sex composition, years of education, handedness and urgency score at the second scan ( P>0.05). Residual urine volume in both groups was less than 10 ml. The OABSS score, 3-day urine diary parameters (frequency of urination/24 h, frequency of urinary incontinence/24 h, frequency of urgency/24 h) and maximum detrusor pressure during urine storage in OAB group were significantly higher than those in HC group, with statistical significance ( P<0.01). The average urination volume/time, bladder capacity at first sensation and maximum bladder capacity in OAB group were significantly lower than those in HC group, and the differences were statistically significant ( P<0.01). In the process of bladder filling to strong desire to void, the detrusor pressure in HC group was stable without DO, and 6 cases in OAB group had DO. Compared to empty bladder state, healthy subjects with strong desire to void showed significantly increased FC within PFC in 5 Brodmann area (BA9, BA10, BA44, BA45, BA46)and 13 edges, such as the BA9(left dorsolateral prefrontal cortex [DLPFC]: ch 4, 5, 7 and right DLPFC: ch 3), BA10(left frontopolar area: ch 12, 21 and right frontopolar area: ch 10, 18), BA44(left pars opercularis Broca's area: ch 15), BA45(left pars triangularis: ch 22), BA46(left DLPFC: ch 6, 14); significantly decreased FC in 3 brain regions (BA9, BA10 and BA46) and 2 edges, such as the BA9(left DLPFC: ch 7), BA10(left frontopolar area: ch21 and right frontopolar area: ch 17), BA46(right DLPFC: ch 9). There was no significant difference in FC within PFC between OAB and HC groups with empty bladder. However, during the strong desire to void state, the FC within PFC in OAB patients was significantly abnormal when compared with HC. OAB patients showed significantly increased FC within PFC in 4 brain regions (BA9, BA10, BA45 and BA46) and 4 edges, such as the BA9(right DLPFC: ch 1 and left DLPFC: ch 7), BA10(right frontopolar area: ch 17), BA45(left pars triangularis: ch 22), BA46(right DLPFC: ch 9, 16); significantly decreased FC in 3 brain regions (BA9, BA10 and BA46) and 4 edges, such as the BA9 (right DLPFC: ch 3 and left DLPFC: ch 4), BA10(left frontopolar area: ch 12, 21), BA46(left DLPFC: ch 14) Conclusion:Compared with HC group, the PFC in OAB group showed significant abnormalities, which may lead to "dyssynergia" of PFC internal functions, result in frontal lobe dysfunction, involving sensory integration, motivation drive, emotional control and decision whether to urinate or not, etc., leading to urinary control dysfunction, which manifested as typical clinical symptoms of OAB. Our findings contribute to the understanding of the central pathogenesis of OAB and may provide a theoretical basis for the emergence of targeted brain therapy in the future.

Objective:Evaluate the influence of different pressure transmission media of urodynamic water filled catheter(WFC) and air charged catheter(ACC) on the pressure measurement results to determine whether they can be used interchangeably.Methods:The results of 2 147 patients who underwent urodynamic examination in our hospital from January 2014 to December 2020 were retrospectively analyzed. A total of 2 538 times of bladder manometry data were obtained, including 1 299 times in WFC group, 856 times in male and 443 times in female, aged 37(24, 50)years, course of disease 1.2(0.4, 5.0) years, 1 130 times in neurogenic bladder(NB)and 169 times in non-neurogenic bladder(N-NB); In ACC group, there were 1 239 times, 773 times for male and 466 times for female, with age of 37(24, 55)years, course of disease of 1.5(0.5, 6.0)years, 1 040 times for Nb and 199 times for N-NB. There was no significant difference in baseline data of general clinical data between the two groups. The intravesical pressure(Pves), intra-abdominal pressure(Pabd)and detrusor pressure(Pdet) of WFC and ACC patients during filling and urination were analyzed. For traumatic spinal cord injury(SCI) and idiopathic patients, the two sets of pressure measurement data were analyzed separately. Nonparametric test and Chi-square test were used to compare the Pves, Pabd, and Pdet recorded by the two manometry catheters before, at the end and after urination, the maximum detrusor pressure at DO(Pdet.max-DO), and the maximum detrusor pressure during spontaneous urination (Pdet. max) and the detrusor pressure (Pdet.Qmax) corresponding to the maximum urine flow rate, the maximum urethral pressure (MUP) and the maximum urethral closure pressure (MUCP) during resting urethral pressure profile, and the initial cough Pdet signal pattern (typeⅠ, typeⅡand typeⅢ).Results:Regardless of the cause, the Pabd values measured by ACC were significantly higher than WFC before filling, end filling and after voiding[18(10, 26)cmH 2O vs.15(11, 21)cmH 2O; 23(16, 31)cmH 2O vs. 20(14, 26)cmH 2O; 23(15, 31)cmH 2O vs.18(12, 24)cmH 2O], and Pdet were significantly lower than WFC[0(0, 0) cmH 2O vs. 0(0, 1)cmH 2O; 5(1, 13)cmH 2O vs. 9(4, 17)cmH 2O; 6(1, 12)cmH 2O vs. 7(3, 14)cmH 2O]. In the initial cough state, Pves and Pabd increase value were also significantly lower than that of WFC [22(12, 36)cmH 2O vs. 23(14, 38)cmH 2O; 20(10, 33)cmH 2O vs. 21(12, 36)cmH 2O]. The Pves measured by ACC was also significantly higher than WFC before filling and after voiding[18(10, 27)cmH 2O vs. 16(11, 21)cmH 2O; 30(22, 39)cmH 2O vs. 26(20, 36)cmH 2O]. Maximum urethral pressure (MUP) and maximum urethral closure pressure (MUCP) measured by ACC were significantly higher than WFC [91(69, 118)cmH 2O vs.81(64, 106)cmH 2O; 77(55, 103)cmH 2O vs. 68(48, 91)cmH 2O], and there were no significant differences in Pdet.max-DO、Pdet.max和Pdet.Qmax. For patients with traumatic SCI, the Pves measured by ACC was significantly higher than WFC before filling[15(10, 24)cmH 2O vs. 14(10, 20)cmH 2O], and only MUP was significantly higher than WFC in the measurement of urethral pressure[95(71, 119)cmH 2O vs. 85(65, 112)cmH 2O], and there were no significant differences in Pdet.max-DO, Pdet.max, Pdet.Qmax and MUCP. For idiopathic patients, Pves measured by ACC before filling and after urination were significantly higher than WFC[25(20, 29)cmH 2O vs. 18(11, 23)cmH 2O; 35(29, 44)cmH 2O vs. 28(20, 38)cmH 2O], while Pdet.max-DO, Pdet.max, Pdet.Q max, MUP and MUCP were not significantly different in different pressure measurement systems. For the comparison of the initial cough Pdet signal pattern, ACC is easier to detect type Ⅰ, and WFC is easier to detect type Ⅱ and type Ⅲ. Conclusions:Compared with WFC, ACC measured higher Pves and Pabd and lower Pdet in resting state, and lower Pves and Pabd in initial cough state. The pressure values and signal pattern measured by WFC and ACC are not completely consistent, so they cannot be used interchangeably.

PURPOSE: The purpose of this study is to investigate the impact of transitional care by a nurse-led multidisciplinary team (MDT) on clinical outcomes and quality of life of patients with ankylosing spondylitis. METHODS: A randomized control study design was used. Subjects were allocated randomly to an experimental group and a control group. The experimental group received intensive transitional care by a nurse-led MDT, whereas the control group received routine nursing care. Disease activity, spinal mobility, comprehensive function, health service utilization, and quality of life were assessed at the baseline and at six months with the Bath Ankylosing Spondylitis Metrology Index, the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), the Bath Ankylosing Spondylitis Functional Index (BASFI), a health service utilization questionnaire and version 2 of the Short Form-36 health survey. RESULTS: Compared with the baseline, the BASDAI, BASFI, emergency visits, hospitalizations, hospitalization days, and bodily pain, vitality, mental health, total score, and average score of version 2 of the Short Form-36 health survey were improved in the experimental group (p < .05), whereas only bodily pain, vitality, and role-emotional were improved in the control group p < .05). At six months, the experimental group exhibited significantly more improvement on the BASDAI, BASFI, hospitalizations, all domains except Role-physical as well as total score and average score p < .05) compared with the control group. CONCLUSION: A MDT-based nurse-led transitional care improves clinical outcomes and quality of life of patients with ankylosing spondylitis. Future research should be carried out on modes of follow-up and family support.

BACKGROUND:Poly(lactide-co-glycolide) (PLGA) scaffold is widely used in tissue engineering, but its poor cel adhesion ability and strong hydrophobicity limit its further development and application. OBJECTIVE: To study the biocompatibility of electrospun poly (lactide-co-glycolide)/polyethylene glycol (PLGA-PEG) nanofibrous scaffolds with mouse neural stem celsin vitro. METHODS:Neural stem cels were isolated from embryos of CD-1 mice at 15 embryonic days. Electrospinning was used to prepare PLGA and PLGA-PEG nanofibrous scaffolds. Scanning electron microscope was used for scanning observation of scaffolds. The 5th passage neural stem cels were seeded onto PLGA and PLGA-PEG scaffolds respectively, and culturedin vitro. RESULTS AND CONCLUSION: Interconnected porous network structure was observed in both two kinds of scaffolds under the scanning electron microscope. Fiber diameters and porosities of PLGA and PLGA-PEG scaffolds showed no significant differences (P > 0.05). Cel Counting Kit-8 detection showed neural stem cels grew wel on both two kinds of scaffolds and the absorbance value of two groups increased continuously with incubation time (1, 3, 5, 7, 9, 11 days). And there were statisticaly significant differences in the absorbance values between two groups at each time point (P < 0.05). Moreover, the cel adhesion rate was significantly higher in the PLGA-PEG group than in the PLGA group at 3, 6, 9 hours of culture (P < 0.05). Hoechst 33342 staining showed normal morphology and quality of the nuclei, and significantly more cels were observed in the PLGA-PEG group than the PLGA group (P < 0.05). Under the scanning electron microscope, compared with the PLGA scaffold, the PLGA-PEG scaffold was better for growth and matrix secretion of neural stem cels. In conclusion, PLGA-PEG nanofibrous scaffolds prepared by electrospinning are safe, non-toxic and suitable for neural stem cels growth with wel biocompatibility, appropriate aperture and porosity.

Objective To investigate effect of Dahuang Fuzi decoction on alveolaur epithelial barrier in rats with lung injury with severe acute pancreatitis. Method Ninty-six health SD rats were randomly divided into three groups: sham operation group, SAP-ALI group, Dahuang Fuzi decoction group, and then according to the time point of sacrifice after operation, each group was subdivided into 3,6,12,24 hour subsets ( each, n = 8). After the belly of a rat in the sham operation group was cut open, the pancreas was flipped several times,and then a stoma was made in the jejunum to form its fistula. In the SAP-ALl group,1 mL/kg sodium taurocholate was reversely injected into the pancreatobile duct to establish the model of SAP, and then the jejimum fistula was performed. The SAP-ALI model in Dahuang Fuzi decoction group was treated by injection of 10ml of Dahuang Fuzi decoctionon into the fistula respectively. Blood was collected from heart to detect serum amvlase and endotoxin (ET) levels before the rat being executed. The lung histopathologic changes, pulmonary injury scores and wet/dry weight(W/D) ratios were observed after the rats were executed. The alveolar liquid clearance rate(ALCR), total lung water content (TLW), extravascular lung water content(EVLW) and alveolar epithelial permeability (AEP) were examined in 3,6, 12,24 h after injury.Results There was continuous increase of AEP,TLW and EVLW,as well as progressive reduction of ALCR compared with sham operation group at 3,6,12,24 h after operation. Compared with SAP-ALI group, there was continuous decrease of AEP,TLW and EVLW, and elevated of ALCR at 3,6,12,24 h after operation.Conclusions Dahuang Fuzi decoction can significantly reduce alveolaur epithelial barrier and degree of lung tissue of SAP-ALI rats by inhibiting the elevation of LPS and inflammation reaction.
