OBJECTIVES: Stress urinary incontinence (SUI) is a common condition among women that severely impairs quality of life. Pelvic floor proprioceptive training (PFPT) has attracted increasing attention for its potential to enhance pelvic floor muscle function and alleviate SUI symptoms. This study aims to observe and compare the clinical efficacy of PFPT combined with electroacupuncture, electrical stimulation, and biofeedback therapy versus conventional therapy consisting of electroacupuncture, electrical stimulation, and biofeedback alone in women with SUI, and to explore the role of PFPT in improving symptom and functional outcomes. METHODS: In this randomized controlled trial, 72 women with mild to moderate SUI were recruited from the Department of Rehabilitation Medicine at Third Xiangya Hospital, Central South University, between December 2021 and October 2023. Participants were randomly assigned to an experimental group (n=36) or a control group (n=36). Both groups received health education. The control group underwent electroacupuncture combined with electrical stimulation and biofeedback therapy, while the experimental group additionally received PFPT 3 times per week for 4 weeks. The primary outcome was assessed using the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF). Secondary outcomes included pelvic floor muscle strength, bladder neck mobility, and balance ability. The ICIQ-SF was reassessed at 1, 3, 6, and 12 months post-treatment. RESULTS: Both groups showed statistically significant improvements in all parameters after treatment (all P<0.05). However, there were no statistically significant differences between groups in most measures (all P>0.05). The experimental group demonstrated longer single-leg stance duration with eyes closed than the control group (left leg: P=0.026; right leg: P=0.006), with a significant increase from baseline (P<0.001). At 6 months post-treatment, the cure rate in the experimental group was significantly higher than that in the control group (P=0.037). CONCLUSIONS Conventional therapy effectively improves SUI symptoms, but adding PFPT provides notable additional benefits, including enhanced balance ability and sustained mid-term cure rates. These findings suggest that PFPT is a valuable adjunct to standard SUI management strategies.

Objectives:Coronary slow flow(CSF)has long been regarded as a marker of coronary microvascular dysfunction(CMD).This study aims to evaluate the diagnostic value of CSF for CMD in patients with angina and nonobstructive coronary arteries(ANOCA).Methods:The study data were derived from the ANOCA-CMD prospective cohort study.All enrolled patients underwent coronary angiography and concurrent coronary physiological assessments in the left anterior descending artery using pressure-wire and thermodilution techniques to obtain coronary flow reserve(CFR)and the index of microcirculatory resistance(IMR).Based on the results,CMD was classified into four subtypes:CMD with elevated IMR(IMR≥25),CMD with reduced CFR(CFR<2.5),CMD with either reduced CFR or elevated IMR(CFR<2.5 or IMR≥25),and CMD with both reduced CFR and elevated IMR(CFR<2.5 and IMR≥25).The corrected thrombolysis in myocardial infarction(TIMI)frame count(CTFC)in the left anterior descending artery was calculated from coronary angiography images,with CSF defined as CTFC>27.This study evaluated the correlation between CTFC,CFR,and IMR,and investigated the diagnostic value of CSF for CMD in ANOCA patients.Results:A total of 103 ANOCA patients were enrolled in this study,with a mean age of(64.2±10.6)years,and 53.4％were female.Among them,57 patients(55.3％)were diagnosed with coronary slow flow.Patients with slow flow had higher IMR(P<0.001)and CFR(P=0.041).Similarly,the proportion of CMD with elevated IMR was higher in the slow flow group(P<0.001),while the proportion of CMD with reduced CFR was lower(P=0.044).There was no significant difference between the groups in the proportions of CMD with either reduced CFR or elevated IMR or CMD with both reduced CFR and elevated IMR(all P>0.05).CTFC was positively correlated with hyperemic mean transit time(r=0.424,P<0.001),IMR(r=0.430,P<0.001),and CFR(r=0.211,P=0.032).The area under the curve(AUC)of CTFC for diagnosing CMD with elevated IMR was 0.721(95％CI:0.623-0.819)with an accuracy of 67％(57％,76％),for diagnosing CMD with reduced CFR was 0.610(95％CI:0.499-0.720)with an accuracy of 60％(50％,70％),for diagnosing CMD with either reduced CFR or elevated IMR was 0.549(95％CI:0.425-0.673)with an accuracy of 47％(37％,57％),and for diagnosing CMD with both reduced CFR and elevated IMR was 0.582(95％CI:0.471-0.693)with an accuracy of 47％(37％,57％).Thus,CSF demonstrated limited diagnostic values across all subtypes of CMD.Conclusions:In ANOCA patients,CSF cannot serve as an effective diagnostic marker for CMD.Therefore,in clinical practice,the slow flow phenomenon should not be directly equated with the presence of coronary microvascular dysfunction in ANOCA patients.

Objective:To investigate the value of peripheral blood neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and serum lactate dehydrogenase (LDH) levels for predicting the occurrence of radiation pneumonia (RP) in small cell lung cancer.Methods:A total of 84 patients with small cell lung cancer who received image-guided radiotherapy in Xuzhou Cancer Hospital between September 2019 and September 2022 were retrospectively analyzed. They were divided into an RP group ( n = 25) and a non-RP group ( n = 59) according to whether RP occurred. Peripheral blood NLR and PLR and serum LDH levels were compared between the two groups before and after radiotherapy. The receiver operating characteristic curve (ROC curve) was used to analyze the value of peripheral blood NLR, PLR, and serum LDH levels for the diagnosis of RP in small cell lung cancer. Results:Before radiotherapy, there were no significant differences in peripheral blood NLR and PLR between the two groups (both P > 0.05). After radiotherapy, peripheral blood NLR and PLR in the RP group were (3.39 ± 0.81) and (129.06 ± 24.90), respectively, which were significantly higher than those in the non-RP group [(2.54 ± 0.71), (104.76 ± 26.26), t = 3.61, 3.83, both P < 0.05]. The NLR (2.86 ± 0.30) and PLR (110.07 ± 10.05) were the lowest in patients with grade 2 RP and they were highest in patients with grade 4 RP [(4.49 ± 0.63), (168.88 ± 14.11)]. The grade of RP was positively correlated with peripheral blood NLR and PLR. The sensitivity of peripheral blood NLR in the diagnosis of RP was 88.0%, the specificity was 66.1%, and the area under the curve (AUC) was 0.791. The sensitivity of PLR in the diagnosis of RP was 48.0%, the specificity was 94.9%, and the AUC was 0.735. The sensitivity of NLR combined with PLR in the diagnosis of RP was 92.0%, the specificity was 59.3%, and the AUC was 0.801. There was no significant difference in serum LDH levels between the two groups before and after radiotherapy (both P > 0.05). Logistic regression analysis showed that NLR and PLR were risk factors for RP in patients with small cell lung cancer ( OR = 2.309, 1.037; 95% CI: 1.061-5.024, 1.004-1.071). Conclusion:In patients with small cell lung cancer who develop RP, peripheral blood NLR, and PLR are markedly elevated compared with those in patients who do not develop RP, and combined detection of peripheral blood NLR and PLR has a high value for early diagnosis of RP in patients with small cell lung cancer.

Objective:To isolate and identify a phage that can specifically lyse Salmonella enteritidis from the environment, and provide a theoretical and research basis for its use in food safety prevention and control through the exploration of the biological characteristics of the phage and the efficacy of lysing bacteria. Methods:The double-layer agar method was applied to isolate phages, and the pH stability, thermal stability, host range, one-step growth curve of the phage were determined. The phage morphology was observed by transmission electron microscopy. Next-generation sequencing was performed for the phage genome, and the lysis efficiency was evaluated.Results:Salmonella enteritidis phage JD01 had a (58±3) nm icosahedral head, a (120±5) nm tail, a thin bottom plate of about 17 nm and 5-6 spines at the tail end. The genome of phage JD01 was composed of 44 880 bp with a GC content of 50.17%, and it contained 63 putative open reading frames without any tRNA genes. The genome comparison and phylogenetic analysis revealed that phage JD01 was a novel phage belonging to the class Caudoviricetes, the family Guernseyvirinae, and the genus Jerseyvirus, lacking virulence genes and drug resistance genes. It survived below 70℃ and pH4.0-12.0, and the lysed bacteria had genus specificity. The phage JD01 had a good bactericidal effect on Salmonella enteritidis in contaminated liquid eggs. Conclusions:Phage JD01 has strong lytic activity and a wide host range, and has great potential application in food safety and control of Salmonella enteritidis pollution, which can be considered for the development of food safety biological control agents.

Objective:To explore the adverse event (AE) risk signals of romiplostim, and provide reference for the safe use of the drug in clinic.Methods:The adverse event reports on romiplostim included in the US FDA Adverse Event Reporting System from the first quarter of 2008 to the second quarter of 2022 were collected. AEs were standardized using preferred term (PT) in the Medical Dictionary for Regulatory Activities. The general situation of patients and the outcome of AEs were extracted from the AE reports and analyzed descriptively and statistically. The AE risk signals of romiplostim was explored using the reporting odds ratio ( ROR) method and the proportional reporting odds ratio ( PRR) method. The positive signal PT was set as that the number of AE reports was 3 and more and the lower limit of the 95% confidence interval ( CI) of the ROR and PRR were greater than 1. Results:A total of 12 222 AE reports with romiplostim as the primary suspected drug were collected. Among the 12 222 patients involved, 10 295 had gender records, including 4 818 males and 5 477 females; 3 789 patients with age records, ranging from 0 to 98 years, with an average age of 58 years; 5 919 patients with AE outcome records, the patient number of hospitalizations, death, life-threatening, disabling, and congenital malformation due to AEs were 3 092, 2 305, 363, 152, and 7, respectively. Twelve thousand two hundred and twenty-two AE reports involved 2 090 PTs, which occurred 20 639 times. Signal mining was performed on the top 100 PTs in the number of reports and 42 positive signals were detected. The top 5 PTs in the number of AE reports were decreased platelet count (PLT) (1 510 patients), lack of efficacy (1 488 patients), decreased efficacy (921 patients), abnormal PLT (857 patients), and death (853 patients). The PTs with signal intensity ranking in the top 5 were bone marrow reticulin fibrosis ( ROR=631.43, PRR=341.43), abnormal bone marrow biopsy ( ROR=202.73, PRR=159.36), abnormal platelet count ( ROR=200.90, PRR=159.49), splenectomy ( ROR=118.82, PRR=102.55) and thrombocytosis ( ROR=84.66, PRR=76.14). There were 10 PTs not recorded in the drug instruction, whose signal intensity from high to low in the order were splenectomy, chronic lymphocytic leukemia, hemolysis, hospitalization, pleural effusion, sepsis, bone pain, off-label drug use, hemoglobin reduction, and migraine. Conclusions:Bone marrow reticulin fibrosis and abnormal platelet count, as well as the resulting bleeding and thrombotic complications, are the AEs that need to be monitored during the use of romiplostim. Among the 10 PTs not recorded in the drug instruction, pleural effusion and sepsis need to be noticed.

Objective:To investigate the sodium intake, potassium intake, sodium- potassium ratio and influencing factors of family cooks and members in six regions of China.Methods:Using the multistage random sampling method, a total of 1 576 family cooks and their family members were recruited from 6 regions in China. Questionnaire survey and physical examination were conducted to collect basic information. 24 h urine was collected to test 24 h urinary sodium and potassium levels.Results:After excluding unqualified urine samples, a total of 1 530 people were included in the study. For all participants, 24 h urine sodium value was (4.39±1.93) g, 24 h urine potassium value was (1.59±0.62) g and sodium-potassium ratio was 5.02±2.18. 24 h urinary sodium was negatively correlated with age, female, junior high school education or above, and annual family income ( P<0.05), and positively correlated with perceived salty taste, BMI and SBP ( P<0.05). The 24 h urine potassium value was negatively correlated with eating out almost everyday ( P<0.05), but positively correlated with BMI and unwillingness to reduct salt ( P<0.05). The sodium-potassium ratio was negatively correlated with age, female and junior high school education or above annual family income ( P<0.05), and positively correlated with perceived salty taste, SBP and eating out 3-5 d/week ( P<0.05). Conclusions:The 24 h urinary sodium value and sodium potassium ratio of family cooks and family members in six regions of China are still at high level, while the 24 h urine potassium value is low, with multiple factors. Therefore, it is necessary to carry out long-term comprehensive salt reduction intervention for family cooks and their members.

Objective: To analyze the blood pressure changes of adults aged 18-59 years in rural area of Shanxi province based on a cohort study, and provide reference for the study of the blood pressure level of rural residents and hypertension prevention and control in rural areas in China. Methods: Data were obtained from Shanxi Nutrition and Chronic Disease Family Cohort from 2002 to 2015. Subjects aged <18 years or ≥60 years and individuals with hypertension at baseline survey in 2002, and those who had taken antihypertensive drugs for nearly two weeks during the follow-up survey in 2015 were excluded from the study. A total of 1 629 subjects aged 18-59 years were included in the analyses of the blood pressure level and its change from the baseline survey in 2002 to follow-up survey in 2015. Results: The systolic blood pressure (SBP) of the subjects increased from (122.7±10.4) mmHg in 2002 to (132.8±17.6) mmHg in 2015 and the diastolic pressure (DBP) increased from (72.7±6.9) mmHg in 2002 to (78.8±10.3) mmHg in 2015. The SBP in men and women increased with growth rates of 6.7% and 9.5%. While DBP in men and women increased with growth rates of 9.3% and 7.8%. The SBP levels of those aged 18-, 30-, 40- and 50-59 years increased with growth rates of 5.0%, 6.7%, 9.4% and 11.8%. While the DBP of these age groups increased with growth rates of 12.2%, 8.2%, 8.2% and 6.5%. Conclusions The blood pressure of adults aged 18-59 years old in rural area of Shanxi showed a substantially increasing trend. The mean increase level of SBP in women was higher than that in men, and increased with age. While the mean increase level of DBP in men is higher than that in women, and decreased with age.
