Objective To investigate the expression levels of serum miR-186-5p and miR-942-5p in patients with glioma and their clinical significance.Methods A total of 98 patients with glioma who were treated in this hospital from October 2019 to December 2021 were selected as the monitored group,and 101 healthy indi-viduals who underwent physical examinations a the same time were selected as the control group.Quantitative fluorescent PCR(qPCR)method was applied to detect the expression levels of miR-186-5p and miR-942-5p in serum,and multivariate COX regression was applied to analyze the prognostic factors of glioma patients.Re-ceiver operating characteristic(ROC)curve and area under curve(AUC)were used to analyze the diagnostic value of serum miR-186-5p and miR-942-5p in glioma.Kaplan-Meier survival curve was used to analyze the re-lationship between serum miR-186-5p and miR-942-5p expression and prognosis of patients.Results The ex-pression level of serum miR-186-5p in monitored group was lower than that in the control group(P＜0.05),and the expression level of miR-942-5p was higher than that in the control group(P＜0.05).The AUC of ser-um miR-186-5p and miR-942-5p in the diagnosis of glioma alone and in combination were 0.735,0.809 and 0.895,respectively.There were significant differences in the proportion of low miR-186-5p expression and high miR-942-5p expression in serum of patients with different preoperative Karnofsky performance status(KPS)scores,World Health Organization(WHO)grades and local infiltration(P＜0.05).The 2-year surviv-al rate of patients with high expression of miR-186-5p was higher than that of patients with low expression of miR-186-5p(x2=6.455,P=0.011).The 2-year survival rate of patients with high miR-942-5p expression was lower than that of patients with low miR-942-5p expression(x2=9.858,P=0.002).miR-186-5p was a protective factor for mortality in glioma patients(P＜0.05),while miR-942-5p was a risk factor(P＜0.05).Conclusion Serum miR-186-5p expression level decreases and miR-942-5p expression level increases in glioma patients,both of which have certain diagnostic value for the occurrence of glioma.

Objective To conduct a retrospective analysis of the correlation among bedaquiline(BDQ)plasma concentrations,relevant clinical factors,and disease prognosis.Methods In this retrospective study,22 patients diagnosed with rifampicin-resistant tuberculosis(RR-TB),multidrug-resistant tuberculosis(MDR-TB),or pre-extensively drug-resistant tuberculosis(pre-XDR-TB)were enrolled.These patients were admitted to the tuberculosis ward of our hospital between February 2022 and October 2024.All patients were administered a treatment regimen containing BDQ.The cohort comprised 6 RR-TB patients(27.27%),12 MDR-TB patients(54.55%),and 4 pre-XDR-TB patients(18.18%).Peripheral blood samples were collected 2 hours after the oral administration of Bedaquiline.The plasma concentration of Bedaquiline was measured using liquid chromatography-tandem mass spectrometry(LC-MS/MS).Spearman correlation analysis was performed using R studio software with the ggplot2 and corrplot packages.The factors included the blood concentration of bedaquiline,electrocardiogram QTcF(QT interval corrected by the Fridericia method),liver and kidney function parameters,weight,age,body mass index,sex,blood uric acid level,serum creatinine level,and other relevant indicators.Results In 22 patients treated with BDQ,the plasma concentration reached a peak after 1.5 weeks of administration,and gradually stabilized after 2 weeks.The plasma concentration was approximately 1-3 μg/mL.After 24 weeks of withdrawal of bedaquiline,patients were continued to monitor their bedaquiline concentration and found that BDQ blood concentration in peripheral blood was approximate 1 μg/mL up to 36 weeks.The serum concentration of BDQ was not correlated with age,body weight,BMI,ALT,AST,GGT,TDiL,urea,uric acid and QT interval,but correlated with sputum negative transformation and serum creatinine.The correlation analysis between serum concentration of BDQ and acid-fast staining of sputum smear showed,the difference was significant(r=0.35,P<0.05).In addition,the correlation analysis between serum BDQ concentration and serum creatinine showed,the difference was significant(r=0.34,P<0.05).The results of multiple linear regression analysis showed that BDQ blood concentration was positively correlated with Scr level,and Scr was an independent factor affecting BDQ blood concentration.20 cases(90.9%,20/22)were cured,1 case died of Covid-19 virus infection,1 case was recurrence.Conclusions Regimens containing bedaquiline seem to exhibit relatively high safety profiles and good tolerability among patients with rifampicin-resistant,multidrug-resistant,or pre-extensively drug-resistant tuberculosis,typically yielding favorable treatment outcomes.The BDQ shows a positive correlation with serum creatinine(SCr).Consequently,close surveillance of BDQ levels and renal function remains of utmost importance throughout the treatment course.

At present,there are some shortcomings in China's medical humanities education,such as inadequate adaptation to the needs of the development of philosophy and social sciences with Chinese characteristics,and insufficient early warning of crises brought about by emerging medical technologies.The concept of"a community of common health for mankind"had been established in the appearance context of medical humanities education,which also gave medical humanities education a richer contemporary significance and development opportunities.Taking the courses of medical ethics and health law as examples,the concept of"a community of common health for mankind"fits well with the core of medical humanities education in terms of value significance,logical mechanisms,and content elements,which is more conducive to highlighting the localized results of medical humanities research.Therefore,the existing theoretical frameworks should be integrated with the concept of"a community of common health for mankind",to create a medical humanities education system with Chinese characteristics and universal significance,as well as to enhance the quality and effects of humanities education by integrating the disciplinary systems,education modes,education chains,and other paths.

Objective:To discuss the improvement effect of Shenshuai Yingyang Capsule in the renal osteodystrophy model rats and its effect on the bone morphogenetic protein(BMP)-7/Smads signaling pathway,and to clarify the relationship between renal function and bone metabolism in the renal osteodystrophy model rats.Methods:Fifty SPF SD rats were selected,and 10 of which were randomly chosen as control group,and the remaining 40 rats were used to establish the renal osteodystrophy model.Thirty successful modeling rats were divided into model group,positive control group,and Shenshuai Yingyang Capsule group,and there were 10 rats in various groups.The rats in control and model groups were given saline,the rats in positive control group were given 0.01 mg·kg-1 calcitriol,and the rats in Shenshuai Yingyang Capsule group were given 1.2 g·kg-1 Shenshuai Yingyang Capsule,all the rats were treated for 12 weeks.HE staining was used to observe the pathomorphology of femur tissue of the rats in various groups;automatic biochemical analyzer and chemiluminescence were used to detect the kidney function and calcium-phosphorus metabolism indicators in serum of the rats in various groups;real-time fluorescence quantitative PCR(RT-qPCR)method was used to detect the expression levels of BMP-7 and Smad1/5/8 mRNA in femur tissue of the rats in various groups;Western blotting method was used to detect the expression levels of BMP-7,phosphorylated BMP-7(p-BMP-7),Smad1/5/8,and phosphorylated-Smad1/5/8(p-Smad1/5/8)proteins in femur tissue of the rats in various groups.Results:The HE staining results showed that there was normal trabecular arrangement in control group with unchanged osteoblasts and osteoid area.In model group,the trabecular width and average osteoid area were increased,while the number of osteoblasts was decreased.In positive control and Shenshuai Yingyang Capsule groups,the trabecular width and average osteoid area were decreased,and the number of osteoblasts was increased.Compared with control group,the levels of blood urea nitrogen(BUN)and serum creatinine(Scr)of the rats in model group were increased(P<0.05);compared with model group,the levels of BUN and Scr of the rats in positive control and Shenshuai Yingyang Capsule groups were decreased(P<0.05);compared with positive control group,the levels of BUN and Scr of the rats in Shenshuai Yingyang Capsule group were decreased(P<0.05).Compared with control group,the level of calcium ion(Ca2+)in serum of the rats in model group was decreased(P<0.05),and the levels of phosphorus ion(P3-),parathyroid hormone(PTH),and alkaline phosphatase(ALP)were increased(P<0.05);compared with model group,the levels of Ca2+in serum of the rats in positive control and Shenshuai Yingyang Capsule groups were increased(P<0.05),and the levels of P3-,PTH,and ALP were decreased(P<0.05);compared with positive control group,the level of Ca2+in serum of the rats in Shenshuai Yingyang Capsule group was increased,and the levels of P3-,PTH,and ALP were decreased(P<0.05).The RT-qPCR results showed that compared with control group,the expression levels of BMP-7 and Smad1/5/8 mRNA in femur tissue of the rats in model group were decreased(P<0.05);compared with model group,the expression levels of BMP-7 and Smad1/5/8 mRNA of the rats in positive control drug group and Shenshuai Yingyang Capsule group were increased(P<0.05);compared with positive control group,the expression levels of BMP-7 and Smad1/5/8 mRNA in femur tissue of the rats in Shenshuai Yingyang Capsule group were increased(P<0.05).The Western blotting results showed that compared with control group,the expression levels of BMP-7,p-BMP-7,Smad1/5/8,and p-Smad1/5/8 proteins in femur tissue of the rats in model group were decreased(P<0.05);compared with model group,the expression levels of BMP-7,p-BMP-7,Smad1/5/8,and p-Smad1/5/8 proteins in femur tissue of the rats in positive control group and Shenshuai Yingyang Capsule group were increased(P<0.05);compared with positive control group,the expression levels of BMP-7,p-BMP-7,Smad1/5/8,and p-Smad1/5/8 proteins in femur tissue of the rats in Shenshuai Yingyang Capsule group were increased(P<0.05).Conclusion:Shenshuai Yingyang Capsule can improve the kidney function and calcium-phosphorus metabolism disorders in the renal osteodystrophy model rats,promote the proliferation of the bone marrow stromal cells,and enhances the bone metabolism;its mechanism may be related to the activation of BMP-7/Smads signaling pathway.

Objective: To analyze the emotional and behavioral problems and associated factors of the only and non only child, and to provide some clues for further monitoring and intervention of psychological and behavioral development among preschool children. Methods: Using a convenience sampling method, a total of 45 065 children enrolled in 153 kindergartens in 23 districts and counties of Chengdu were selected from May to June 2021 to investigate demographic characteristics and children s psycho behavioral development through online questionnaires filled out by their guardians. The Chi square tests were used to analyze whether the differences in abnormality rates of each dimension were statistically significant between the only and non only children. The emotional and behavioral problems of only children and non only children were analyzed by propensity score measurement. Results: The detection rate of abnormal emotional behavior problems in children was 6.10%, including 6.34% in the only child group and 5.84 % in the non only child group. After matching, total difficulty score, and scores of emotional symptoms, conduct problems, hyperactive attention deficit, peer interaction, and social behavior differed between the only child group and the non only child group ( t =9.91, 8.97, 3.91, 15.57, -5.46, 4.08, P <0.01). Conclusion In terms of the total score of difficulties, emotional symptoms, moral problems, and hyperactivity attention defects, the non only child is better than the only child，but the opposite is true in terms of peer interaction and social behavior. Mental health conditions among the only child should be paid more attention. Whether or not the only child should be taken as an important consideration for preschool children s mental health care.
