Objective To study the effects of different enteric-coated aspirin tablets on upper gastrointestinal tract in the elderly. Methods 404 inpatients aged more than 65 years in last three years who took enteric-coated aspirin tablets (100mg/d) for more than three months were analyzed.They were divided into two groups: bayaspirin-treated group (232 cases) and control group with ordinary enteric-coated aspirin tablet treatment (172 cases). The clinical data and the results of gastroseopy were compared between two groups, and the effects of two kinds of enteric-coated aspirin tablets on upper gastrointestinal tract in the elderly were analyzed by Chi-square test. Results The upper gastrointestinal bleeding rates were 20.3% in Bayaspirin-treated group (47/232) and 32.0% in control group (55/172), and there was significant difference between two groups(χ2=7.19,P<0.01)Gastroscopy indicated that gastroduodenal inflammation occurred in 16 patients (6.9% and peptic ulcer occurred in 8 patients (3.5%) in bayaspirin-treated group, while gastroduodenal inflammation occurred in 12 patients (7.0%) and peptic ulcer occurred in 36 patients(20.9%)in control group. The difference of the incidence of peptic ulcer between two groups had statistical significance(χ2= 31.10,P<0.01). The incidences of gastrointestinal adverse reactions were 8.6% (20/232) in bayaspirin-treated group and 23.3% (40/172) in control group, and there was a statistical difference between two groups. Conclusions Compared with ordinary enteric-coated aspirin tablet, bayaspirin has less adverse effects on upper gastrointestinal tract in the elderly and is more safe for treatment.

Objective To preliminarily test the value of gastroesophageal reflux disease questionnaire (GERD-Q) in auxiliary diagnosis of gastroesophageal reflux disease(GERD) in infants and young children.Methods From January 2011 to February 2014,148 infants and 87 young children with suspected GERD symptoms were enrolled in the outpatient and inpatient departments of Wuhan Women and Children's Medical Care Center.The diagnosis of GERD were made through 24 h esophageal pH monitoring and upper gastrointestinal hysterosalpingography.Those with any examinations being positive were brought into GERD group,and the others into the control group.All cases had been surveyed with GERD-Q.Using SPSS17.0 statistical software,the ratio was compared with chi-square test,and the difference of the scores between groups with t test.Results In infants (1 to 11 months),the individual symptom scores (ISS) of the 6 symptoms in the GERD group (n =111) were all higher than those in the control group (37 cases) (P ＜ 0.05),and the composite and symptom scores (CSS) [(131.43 ± 66.56) scores] in the GERD group was higher than that [(33.70 ± 40.03) scores] in the control group (t =8.42,P ＜ 0.05).In young children (1 to 3 years old),the ISS in the GERD group(55 cases) were all higher than those in the control group(32 cases),and the CSS[(98.58 ± 66.75) scores] in the GERD group was also higher than that [(28.50 ± 35.95) scores] in the control group(t =5.49,P ＜ 0.05).Conclusions There is a good correlation for age-specific GERD-Q to distinguish GERD symptoms in infants and young children,which is suitable for the assessment of GERD.

Objective To explore the effect of continuing care on the intermittent catheterization compliance of patients with neurogenic bladder. Methods From January to December, 2015, 60 patients with neurogenic bladder after spinal cord injury receiving intermittent cathe-terization were randomly assigned to control group (n=30) and intervention group (n=30). The control group received routine discharge in-struction, while the intervention group received continuing care in addition. The intermittent catheterization compliance, residual urine vol-ume, urinary tract infection and quality of life were assessed at discharge and three months after intervention. Results After intervention, the intermittent catheterization compliance was better in the intervention group than in the control group (χ2=7.500, P=0.006). The residual urine volume significantly decreased in both groups (t>12.040, P<0.001), and was less in the intervention group than in the control group (t=-2.190, P=0.032), as well as the urinary tract infection rate (χ2=10.800, P=0.001). The score of quality of life increased significantly after intervention in both groups (t>4.572, P<0.001), and was higher in the intervention group than in the control group (t>5.505, P<0.001). Con-clusion Continuing care could improve the intermittent catheterization compliance, reduce the residual urine volume and the urinary tract in-fection rate, and improve the quality of life in patients with neurogenic bladder after discharge.

Objective To investigate the potential effect of Lactobacillus acidophilus (L. acidophilus) on prevention and treatment of neonatal mice infected with human rotavirus (HRV). Methods Sixty 4-day-old kunming mice were randomly divided into control group. HRV infected group, L. acidophilus pretreated group (treated before HRV infection ) and L. acidophilus treated group(treated after HRV infection). The manifestation and pathological changes in small intestine of neonatal mice were observed. The HRV antigen in the feces and intestines were measured by ELISA and fluorescent-focus assay, respectively. Results The severity and duration of diarrhea as well as mortality in L. acidophilus pretreated group and treated group were lower than those in HRV infected group. The duration of HRV-antigens shedding following infection was considerably prolonged in HRV infected group compared to that in L. acidophilus pretreated group and treated group. Furthermore, decreased expression of HRV antigen and little pathological changes in intestinal mucosa were found in L. acidophilus pretreated group and treated group when compared with HRV infected group. Conclusion L. acidophilus may be used as an alternative approach for the prevention and treatment of neonatal mice infected with HRV.

Objective:To establish a predictive model for the progression of acute kidney injury (AKI) to stage 3 AKI (renal failure) in the intensive care unit (ICU), so as to assist physicians to make early and timely decisions on whether to intervene in advance.Methods:A retrospective analysis was conducted. Thirty-eight patients with AKI admitted to the intensive care medicine of the Third People's Hospital of Henan Province from January 2018 to May 2023 were enrolled. Patient data including acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) upon admission, serum creatinine (SCr), blood urea nitrogen (BUN), daily urine output during hospitalization, and the timing of continuous renal replacement therapy (CRRT) intervention were recorded. Based on clinically collected pathological data, standardized creatinine value ratio mean polynomial fitting models were established as the first criterion for judging the progression to stage 3 AKI after data cleansing, screening, and normalization. Additionally, standardized creatinine value ratio index fitting models were established as the second criterion for predicting progression to stage 3 AKI.Results:A total of 38 AKI patients were included, including 25 males and 13 females. The average age was (58.45±12.94) years old. The APACHEⅡ score was 24.13±4.17 at admission. The intervention node was (4.42±0.95) days. Using a dual regression model approach, statistical modeling was performed with a relatively small sample size of statistical data samples, yielding a scatter index non-linear regression model for standardized creatinine value ratio data relative to day " n", with y = 1.246?2 x1.164?9 and an R2 of 0.860?1, indicating reasonable statistical fitting. Additionally, a quadratic non-linear regression model was obtained for the mean standardized creatinine value ratio relative to day " n", with y = -0.260?6 x2+3.010?7 x-1.612 and an R2 of 0.998?9, indicating an excellent statistical fit. For example, using a baseline SCr value of 66 μmol/L for a healthy individual, the dual regression model predicted that the patient would progress to stage 3 AKI within 3-5 days. This prediction was consistent when applied to other early intervention renal injury patients. Conclusion:The established model effectively predicts the time interval of the progression of AKI to stage 3 AKI (renal failure), which assist intensive care physicians to intervene AKI as early as possible to prevent disease progression.

Background: In suckling piglets, transmissible gastroenteritis virus (TGEV) causes lethal diarrhea accompanied by high infection and mortality rates, leading to considerable economic losses. This study explored methods of preventing or inhibiting their production.Bovine antimicrobial peptide-13 (APB-13) has antibacterial, antiviral, and immune functions. Objectives: This study analyzed the efficacy of APB-13 against TGEV through in vivo and in vitro experiments. Methods: The effects of APB-13 toxicity and virus inhibition rate on swine testicular (ST) cells were detected using 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyl tetrazolium bromide (MTT). The impact of APB-13 on virus replication was examined through the 50% tissue culture infective dose (TCID50 ). The mRNA and protein levels were investigated by real-time quantitative polymerase chain reaction and western blot (WB). Tissue sections were used to detect intestinal morphological development. Results: The safe and effective concentration range of APB-13 on ST cells ranged from 0 to 62.5 µg/mL, and the highest viral inhibitory rate of APB-13 was 74.1%. The log10 TCID50 of 62.5 µg/mL APB-13 was 3.63 lower than that of the virus control. The mRNA and protein expression at 62.5 µg/mL APB-13 was significantly lower than that of the virus control at 24 hpi. Piglets in the APB-13 group showed significantly lower viral shedding than that in the virus control group, and the pathological tissue sections of the jejunum morphology revealed significant differences between the groups. Conclusions APB-13 exhibited good antiviral effects on TGEV invivo and in vitro.
