Objective To explore the risk factors for urinary tract infection(UTI)after benign prostatic hyperpla-sia(BPH)surgery,and construct a high-efficiency risk-prediction model based on machine learning algorithms(MLA).Methods This retrospective study included 200 cases of BPH surgically treated in Xinyu Hospital of Traditional Chinese Medicine from May 2020 to April 2023.Twenty-three cases were included in the UTI group,and 177 were enrolled into the non-UTI group.The relevant data were collected and analyzed for the statistically significant factors by univariate logistic analysis by using the SPSS software,MLA-based logistic regression,back-propagation(BP)neural networks and decision classification and regression tree(CRT).And the predictive values of the models established via different algorithms using the area under the receiver operating characteristic curve(AUC)were compared.We assessed the prediction accuracy of the models and identified one with the best prediction efficiency based on the mean absolute error(MAE).Results Univariate analysis indicated statisti-cally significant differences between the UTI and non-UTI groups in age,comorbid diabetes mellitus(DM),urinary catheter-in-dwelling time,prostate volume,preoperative catheterization,preoperative IPSS(P＜0.05).The independent predictive varia-bles for UTI after BPH surgery were shown to be age,IPSS,comorbid DM and prostate volume by the method of multivariate lo-gistic regression model(P＜0.05).Age,urinary catheter-indwelling time,prostate volume and IPSS were assessed as the influ-ence factors by the CRT model(P＜0.05),and prostate volume,IPSS,age and urinary catheter-indwelling time were assessed as the influence factors by the BP neural network model(P＜0.05).Among the 3 risk-prediction models,the one constructed with the BP neural networks exhibited the best prediction efficiency(AUC:0.992,the optimal truncation value:0.912,corre-sponding sensitivity and specificity:0.957 and 0.955).Conclusion The risk-prediction model constructed by MLA and BP neural networks based on the characteristic factors of age,preoperative urinary retention catheterization,urinary catheter-indwell-ing time,IPSS and comorbid DM has a high predictive value for UTI after BPH surgery which can be applied to the identification and management of such high-risk population.

Objective To investigate the correlation mechanism between miR-153-3p and Nrf2 expression in human nucleus pulposus cells and intervertebral disc degeneration(IDD).Methods The oxidative damage model of nucleus pulposus cells was duplicated induced by H2O2.MiR-153-3p inhibitor-NC,si-NRF2-NC,miR-153-3p inhibitor,and si-NRF2 were transfected into nucleus pulposus cells according to the grouping require.The transfection efficiency was detected by RT-qPCR and Western blot.The cell viability was determined by the CCK-8 assay,when the intracellular reactive oxygen species(ROS)levels and the ratio of mitochondrial membrane potential decline were measured by flow cytometry,RT-qPCR was used to detect the expression levels of Nrf2,MMP-3,Col II,PINK1,Parkin,P62,and p38 MAPK.And dual luciferase reporter assay was used to measure luciferase activity.Results(1)HNPCs treated with H2O2 showed a decrease in HNPCs cell viability,a reduction in mitochondrial membrane potential,an increase in ROS levels,and a decrease in Col II expression(P<0.05).And the expression of MMP-3,P62,and p38 MAPK increased,while the expression of PINK1 and Parkin decreased.There was no significant change in Nrf2(P>0.05).(2)Inhibition of miR-153-3p expression in nucleus pulposus cells treated with H2O2 led to increased cell viability,elevated mitochondrial membrane potential,reduced ROS levels,and enhanced Col-II expression,accompanied by decreased expression of MMP-3,P62,and p38 MAPK,while simultaneously increasing the expression of PINK1,Parkin,and Nrf2(P<0.05).(3)When miR-153-3p expression was inhibited and Nrf2 expression was silenced in nucleus pulposus cells treated with H2O2,a notable decline in cell viability and mitochondrial membrane potential was observed,along with a marked increase in ROS levels.Additionally,Col-II expression decreased,whereas the expression of MMP-3,P62,and p38 MAPK increased.However,the expression of Nrf2,PINK1,and Parkin decreased(P<0.05).(4)Dual-luciferase assay analysis revealed binding sites and a binding relationship between miR-153-3p and Nrf2,indicating a negative correlation between miR-153-3p and Nrf2(P<0.05).Conclusion Inhibition of miR-153-3p expression can alleviate H2O2 induced degeneration and fibrosis of nucleus pulposus cells,activate autophagy of damaged nucleus pulposus cells,and delay apoptosis of nucleus pulposus cells.This effect is related to the PINK1/Parkin pathway and p38 MAPK inflammatory response pathway regulated by Nrf2.

AIM: To evaluate the clinical effect of Iron Dextran Dispersible Tablets on patients with chronic heart failure who reduced ejection fraction after 24 weeks. METHODS: From January 2020 to June 2022, forty-five patients with heart failure complicated with iron deficiency and reduced ejection fraction were selected as the research objects. According to the random number table, they were randomly divided into control group and observation group.The control group was given routine anti-heart failure treatment such as Sacubitril Calsartan sodium tablets, while the observation group was given iron dextran dispersible tablets 50 mg three times a day on the basis of the anti-heart failure treatment of the control group for 8 weeks. The 6-minute walking distance, Hemoglobin, Serum Ferritin, N-terminal B-type natriuretic peptide precursor, Left Ventricular Ejection Fraction, Left Ventricular end Diastolic Diameter and 12-item Kansas City Cardiomyopathy Questionnaire (KCCQ-12) overall summary score and clinical summary score were compared between the two groups. RESULTS: There was no significant difference in baseline data between the two groups (P > 0.05). After treatment, the 6-minute walking distance in the observation group was longer than that in the control group, while the serum ferritin level in the observation group was higher than that in the control group. The N-terminal pro-B-type natriuretic peptide level in the two groups was lower than that before treatment, and the left ventricular end diastolic diameter was shorter than that before treatment, and the left ventricular ejection fraction, clinical comprehensive score and symptom score were higher than that before treatment. The difference was statistically significant (P < 0.05). There was no significant difference in the total incidence of adverse reactions between the two groups (P > 0.05). CONCLUSION: Iron Dextran Dispersible Tablets can improve the exercise endurance and quality of life of patients with chronic heart failure who reduced ejection fraction after 24 weeks.

Urorectal septum malformation sequence (URSMS) is a rare congenital complex malformation characterized by severe abnormalities in the urinary, reproductive and digestive systems. It is difficult to diagnose URSMS by prenatal ultrasound due to its complex and variable manifestations. This paper reported a twin with partial URSMS. Prenatal ultrasound findings included pelvic "trilobe" cystic masses, sacrococcygeal hemivertebral malformations, imperforate anus, and transient ascites. Postnatal examination confirmed the diagnosis of URSMS, as the baby girl was born with anal atresia. Her colon, urethra, and vagina converged and formed a common tract with a single perineal opening. The baby died after her parents' refusal to surgical treatment.

Objective·To investigate the reference range for serum 25-hydroxyvitamin D in pregnant women in Shanghai. Methods·A total of 4969 healthy pregnant women in second trimester were enrolled, in whom there were 554 women aged over or equal to 35 years old and 4415 women aged under 35 years old. Meanwhile, 1048 non-pregnant women in child-bearing period were enrolled. The new born children had no complications of vitamin D deficiency such as rickets. The levels of 25-hydroxyvitamin D of all participants were detected by ELISA. The reference interval was defined as the central 95% range between the 2.5th and the 97.5th percentiles. Results·The 95% reference range for 25-hydroxyvitamin D levels showed a positive skewness distribution in second trimester pregnant women. The median of 25-hydroxyvitamin D levels was 36.8 nmol/L. The maximum was 108.6 nmol/L whereas the minimum was 11.8 nmol/L. The 95% reference range for 25-hydroxyvitamin D levels was from 15.9 nmol/L to 70.3 nmol/L. The median 25-hydroxyvitamin D was 36.6 nmol/L in women less than 35 years old, and 35.5 nmol/L in women aged over or equal to 35 years old. A significant difference was found between women aged under 35 years old and women aged over or equal to 35 years old (Z=-2.75, P<0.05). The median, maximum and minimum of 25-hydroxyvitamin D in non-pregnant women was 38.5 nmol/L, 110.5 nmol/L, 12.1 nmol/L, respectively, which were all higher than those in pregnant women (P<0.05). Conclusion·There was a lack of vitamin D in pregnant women in Shanghai, especially in pregnant women aged over or equal to 35 years old, despite the multivitamin supplements. However, no complications of vitamin D deficiency such as rickets were found in new born children. To determine the reference range of vitamin D in Shanghai is helpful for pregnancy women in taking vitamin supplement, especially important in preventing maternal and fetal complications caused by vitamin D deficiency.

Objective:To observe the efficacy of polyene phosphatidyl choline combined with Hugan tablets in the treatment of drug-induced liver injury. Methods:Totally 80 cases of drug-induced liver injury were randomly divided into the observation group (40 cases )and the control group(40 cases). The observation group was given polyene phosphatidyl choline injections 697. 5mg+5%glucose injections 250ml,ivd,qd,combined with Hugan tablets 1. 44g,po,tid,the control group was given polyene phosphatidyl choline injections 697. 5mg+5%glucose injections 250ml,ivd,qd,and the symptomatic treatment in the two groups was the same. The two groups were treated for 20d. Alanine aminotransferase ( ALT), aspartate aminotransferase ( AST), total bilirubin ( TBIL), glutamyl transpeptidase(GGT) and alkaline phosphatase(ALP)were detected respectively before and after the treatment, and the therapeutic effects were compared between the two groups. Results: After the treatment,the total effective rate in the observation group was 97. 5%,which was significantly higher than that in the control group(P <0. 01),Symptoms,signs and biochemical indices in the two groups were improved obviously. The decrease of ALT,AST and GGT in the observation group after the treatment was obviously lower than that in the control group(P<0. 05). Conclusion: Polyene phosphatidylcholine injections combined with Hugan tablets in the treatment of liver injury is better than polyene phosphatidyl choline, which is worthy of clinical application.

Objective To investigate the incidence and the risk factors of anxiety or depression and in the first degree relatives (FDRs) of patients with type 2 diabetes mellitus ( T2DM ). Methods A total of 102 T2DM patients who visited our hospital from May to July 2010 and their FDRs completed SAS,SDS,and life satisfaction evaluation. The medical history of T2DM patients was collected and compared with their FDRs with or without mental disorders. The correlations of risk factors with anxiety or depression were analyzed, t test or X2 test were used for statistical analysis and a P value less than 0. 05 was considered statistically significant. Results The incidence of anxiety or depression of FDRs was 31.4% and 17.6%,respectively. The life satisfaction score of FDRs with mental disorders was significantly decreased ( t = 4. 26 and 4. 09, P＜0. 05 ). Fasting glucose level of T2DM patients with anxious or depressive FDRs was significantly increased ( t = -2. 48 and -2. 15, P＜0. 05 ). Higher medical cost and multiple treatment strategies were positively correlated with SAS and SDS score of the FDRs. Conclusion Higher incidence of mental disorders and lower satisfaction scores could be found in the FDRs of T2DM patients. Better control of blood glucose and reduced treatment cost and strategies may be useful in improving metal condition and life satisfaction of the FDRs of T2DM patients.

The paper is focused on a kind of portable monitor that is widely used in military hospitals. In order to study the electromagnetic radiation immunity of the monitor, the experiments of electromagnetic radiation caused by radio frequency continuous wave in reverberation chamber and by ultra wide band (UWB) electromagnetic pulse have been done. The study results show that UWB electromagnetic pulse interferes observably the operating state of the monitor. It should be paid high attention to take protective measures. The monitor tested has some electromagnetic immunity ability for radio frequency continuous wave radiation. The frequent abnormal phenomena are baseline drift and waveform distortion. The electromagnetic sensitivity of the monitor is related to the frequency of interference source. The monitor tested is most sensitive to the frequency of 390 MHz.
