Objective To investigate the clinical application value of transrectal real-time tissue elastography(TRTE)guided targeted puncture in the diagnosis of prostate cancer.Methods A total of 52 patients with suspected prostate cancer who were treated in the First People's Hospital of Zhengzhou from January 2020 to December 2022 were selected as the study objects.Preoperative routine transrectal ultrasound and TRTE examination were performed to evaluate the benign and malignant prostates.For the 28 patients with suspected lesions found in TRTE,TRTE-guided targeted puncture(2 needles)+ systematic puncture(8 needles)were performed,for the 24 patients with no suspicious lesions found in TRTE,routine ultrasound-guided systematic puncture(12 needles)was performed.The efficacy of TRTE in the diagnosis of prostate cancer was analyzed and the positive rate of targeted puncture and systematic puncture was compared.Results In this study,25 cases of prostate cancer and 27 cases of benign lesions were ultimately pathologically diagnosed,while a total of 28 cases of prostate cancer and 24 cases of benign lesions were diagnosed with TRTE.The positive predictive value and negative predictive value of the diagnosis were 75.0%(21/28)and 83.3%(20/24),respectively.In 28 patients with suspected lesions found by TRTE,a total of 56 needles were targeted puncture,36 needles were diagnosed with prostate cancer,positive rate was 64.29%(36/56),and a total of 224 needles were systematic puncture,89 needles were diagnosed with prostate cancer,with a positive rate of 39.73%(89/224).The positive rate of prostate cancer by targeted puncture was significantly higher than that by systematic puncture(P<0.05).Conclusion TRTE can better diagnose prostate cancer,and its guided targeted puncture has a higher positive rate in the diagnosis of prostate cancer,which can maximize the positive rate of puncture while reducing the number of puncture needles.

Objective To explore the effects of long non-coding RNA(lncRNA)small nucleolar molecule RNA host gene 12(SNHG12)targeting inhibition of miR-495-3p/phospholipinositol-3-kinase(PI3K)/protein kinase B(Akt)signaling pathway on the proliferation,migration and invasion of prostate cancer cells.Methods The expressions of SNHG12 and miR-495-3p in prostate cancer tissues and cells(LNCaP,C4-2,DU145)were detected with real-time fluorescence quantitative PCR(qRT-PCR).After DU145 cells were divided into si-NC,si-SNHG12,si-SNHG12+anti-miR-NC and si-SNHG12+anti-miR-495-3p groups,the expressions of SNHG12 and miR-495-3p were detected with qRT-PCR;the targeting relationship between SNHG12 and miR-495-3p was determined with dual luciferase assay;cell proliferation was assessed with MTT assay;cell migration and invasion were evaluated with Transwell assay;the protein expressions of proliferating cell nuclear antigen(PCNA),N-cadherin,and E-cadherin were detected with Western blot.Results The expressions of SNHG12 were significantly increased,while the expression of miR-495-3P was significantly decreased in prostate cancer tissues and cells(LNCaP,C4-2,DU145)(P＜0.05).Knockdown of SNHG12 decreased DU145 cell activity,lowered the protein expressions of PCNA and N-cadherin,reduced the number of migrating and invading cells,but increased the protein expression of E-cadherin(P＜0.05).SNHG12 targeted and negatively regulated miR-495-3p,and down-regulation of miR-495-3p reversed the effects of SNHG12 knockdown on the proliferation,migration and invasion of prostate cancer cells.Compared with the si-NC group,the si-SNHG12 group had significantly decreased expressions of p-PI3K and p-Akt(P＜0.05).Compared with the si-SNHG12+anti-miR-NC group,the si-SNHG12+anti-miR-495-3p group had significantly increased protein expressions of p-PI3K and p-Akt(P＜0.05).Conclusion lncRNA SNHG12 can promote the proliferation,migration and invasion of prostate cancer cells through targeted inhibition of miR-495-3p/PI3K/Akt signaling pathway.

Objective:To explore the status quo of pediatric nurses' cognition of death education, and analyze its influencing factors, so as to provide experience and reference for carrying out death education in pediatric wards.Methods:In this study, 827 nurses from 15 children's hospitals in China were investigated by using the scale for evaluating the cognition of death education in medical staff prepared by Zhang Yan-gai, and the related factors affecting the cognition of death education were analyzed. SPSS 23.0 was used for independent-samples t-test and ANOVA analysis, and multiple regression equation was used to further analyze the relationship between the cognitive factors of death education in pediatric nurses. Results:The total score of death education cognition of pediatric nurses was (35.61±5.64) points, which was lower than the median score of 36 points. The degree of death education cognition of pediatric nurses was at the medium-low level. The results of correlation analysis showed that the professional title of nurses (regression coefficient: 0.064, P=0.045), the training demand for death education (regression coefficient: 0.300, P<0.001), and the way of understanding (regression coefficient: 0.018, P=0.003) were independent influencing factors of the death education cognition level of pediatric nurses. Conclusions:Pediatric nurse death education related theoretical knowledge should be improved through various professional trainings. The hospitals should include death education in pediatric nurse continuing education training plan to improve pediatric nurses' cognitive level of death education through a variety of ways and means, promote the application of death education activities carried out in pediatric ward in the hospice care, reduce deaths impact to nurse their own emotions, and alleviate parents' anxiety and painful experience, thereby improving medical satisfaction.

Objective To investigate the reasons for the inconsistent results between the vertical auto profile(VAP)method and bio-chemical homogeneous phase(BHP)method in detecting plasma low-density lipoprotein cholesterol(LDL-C),and provide experimen-tal basis for the accurate and quantitative detection of plasma LDL-C levels.Methods A total of 360 plasma samples from diabetes mellitus patients combined with carotid plaque admitted to the Department of Endocrinology of Ningbo Yinzhou Hospital of Traditional Chinese Medicine during January,2022 and January,2023 were collected.The LDL-C levels of these samples were detected by the VAP method and BHP method,respectively.The VAP method uses software to automatically calculate the area under the LDL-C curve after centrifugation of the sample as the LDL-C level(LDL-CVAP)and the BHP method directly detects the LDL-C level(LDL-CBHP)by the special surfactant method.360 samples were divided into the consistent group(group A)and inconsistent group(group B)ac-cording to the relative deviation between the LDL-CBHP and LDL-CVAP methods.Group B was further divided into the LDL-CBHP on the high side group(Group B1)and LDL-CBHP on the low side group(Group B2).Groups B1 and B2 were divided into B1-1,B1-2,B1-3 and B2-1 groups based on the degree of relative deviation.The percentages of samples and levels of lipoprotein a cholesterol[Lp(a)-C],intermediate-density lipoprotein cholesterol(IDL-C),Lp(a)-C and IDL-C[Lp(a)-C+IDL-C],very low-density lipo-protein cholesterol(VLDL-C),total cholesterol(TC)and total triglyceride(TG)in each group were compared.Results The LDL-CBHP levels of 360 samples were significantly higher than that of LDL-CVAP(P＜0.01).The percentage of samples in group B was significantly higher than that in group A,and that of group B1 was significantly higher than that of group B2(P＜0.05).The levels of Lp(a)-C,IDL-C and Lp(a)-C+IDL-C in groups B1-1,B1-2,and B1-3 were significantly higher than those in group A(P＜0.01).The relative deviation between LDL-CBHP and LDL-CVAP in 360 samples was significantly positively correlated with the levels of Lp(a)-C,IDL-C,and Lp(a)-C+IDL-C(P＜0.01).The maximum correlation coefficient was found in Lp(a)-C+IDL-C.Conclusion The results of plasma LDL-C in diabetes mellitus patients combined with carotid plaque detected by the BHP method are significantly different from those detected by the VAP method,which mainly shows that the results of the BHP method are on the high side.The higher the level of plasma Lp(a)-C+IDL-C,the greater the relative deviation between the BHP method and VAP method.The reason for the high results of LDL-C detected by the BHP method may be related to the fact that LDL-CBHP contains irremovable Lp(a)-C and cholesterol carried by IDL-C.The VAP method can be used as an accurate method for detecting real LDL-C without Lp(a)-C and IDL-C.

Objective: To explore the relationship among jogging risk perception, jogging risk behavior and the incidence of jogging risk, so as to provide a feasible way to reduce the risk of college students extracurricular jogging exercise. Methods: The method of convenience sampling was used to conduct a follow up survey among 470 college students at a university in Beijing participating in extracurricular jogging exercise and the sports world campus app was used to record and monitor jogging exercise. During the tracking period, the jogging related information was counted once a month, a total of 6 times. At the same time, three questionnaires were distributed in three stages to collect relevant information. SPSS 26.0 was used for the descriptive analysis, and AMOS 22.0 was used for correlational analysis. Results: The risk rate of extracurricular jogging exercise of college students during the past academic year was 71.06 %, score of knowledge on jogging risk was(3.68±0.59), was (3.25±0.91)for jogging injury, and was( 3.23± 0.96)for jogging related disease. Significant negative correlation between college students jogging risk perception and jogging risk behavior ( r =-0.34), negative correlation between jogging risk perception and the incidence of jogging injuries ( r =-0.27), and positive correlation between jogging risk behavior and the incidence of jogging injuries ( r =0.28) were observed( P <0.01). PE(physical education) class was the main way of obtaining the knowledge about jogging risks among college students(43.40%). Conclusion College students show high vulnerability for extracurricular jogging related risks, and low level of perception of jogging risks and jogging injuries. Relevant measures need to be taken to improve the cognitive level of running risk among college students, so as to reduce the incidence of running risk.

A case of metachronous bilateral renal pelvic carcinoma was reported. A 55-year-old women underwent left nephroureterectomy for the left renal pelvis cancer in 2011, then she was diagnosed with right renal pelvis carcinoma because of intermittent hematuria in 2014.A transurethral ureteroscopic holmium laser resection of the right renal pelvic tumor, partial right pelvis resection and nephrostomy, instillation with hydroxycamptothecin were taken sequentially to delay the dialysis for 53 months. In 2018, the patient underwent right nephroureterectomy because of recurrence of right renal pelvic carcinoma. The patient was followed up for 17 months postoperatively and there was no recurrence. In this case, patient's renal function was protected by the premise tumor control through a variety of minimally invasive and pharmaceutical therapy, which can provide a reference for the kidney-preserving treatment of high-grade renal pelvis cancer.

Objective:To retrieve, evaluate and integrate relevant evidence on the management of the developmentally supportive environment in the neonatal intensive care unit(NICU), and to provide clinical references.Methods:Evidence on NICU environmental management was retrieved from Guidelines International Network, Joanna Briggs Institute, National Institute for Health and Care Excellence, Scottish Intercollegiate Guide Network, National Guideline Clearinghouse, Registered Nurses′ Association of Ontario, Yimaitong and other Websites, BMJ Best Practice, UpToDate, Cochrane Library, PubMed, Embase, Wanfang Database, CNKI and other database.The evidence included guidelines, evidence summaries, best clinical practice manuals, expert consensus and systematic reviews.The date limit was from the establishment of the databases to March 31, 2021.Results:Totally 16 articles were involved, including 4 guidelines, 9 systematic reviews, and 3 expert consensus.Finally, 20 pieces of best evidence on four aspects were su-mmarized: sound, light, touch, and smell.There were 11 A-level recommendations and 9 B-level recommendations.The evidence suggested that health care workers should reduce noise and protect premature infants from being exposed to bright light, noxious gases, and negative touch stimuli.Besides, benign auditory and olfactory stimuli, circadian light, and mother-infant skin-to-skin contact should be used to promote the development of premature infants.Conclusions:This study is a summary of the recommendations on NICU environmental management.It is well-designed and has achieved fruitful results, showing great significance for reducing environmental stress of premature infants in the NICU.However, the current recommended methods for providing benign stimulation require validation of more high-quality, well-designed research.It is recommended that medical staff should selectively apply the evidence to clinical practice according to the actual situation.

With the economic development and medical progress in China, the incidence of prostate cancer is increasing, and most patients have already developed advanced tumors with poor prognosis when diagnosed. The main cornerstone of treatment for metastatic hormone-sensitive prostate cancer (mHSPC) has always been androgen deprivation therapy (ADT), but most mHSPC will transform into metastatic castration-resistant prostate cancer (mCRPC), how to prolong the time from mHSPC to mCRPC has become a current research hotspot, and several landmark phase 3 clinical trials in recent years have led to rapid changes in patient treatment options, including a variety of drugs with different mechanisms of action (e.g., endocrine therapy, chemotherapy, radiotherapy, immunotherapy, and targeted therapy). This article will focus on the current status and progress of novel endocrine agents in metastatic prostate cancer for clinical use.

Objective To assess the efficacy of immunoprophylaxis against mother-to-infant transmission of hepatitis B virus (HBV) in a real-world setting since the implementation of charge-free hepatitis B immunoglobulin (HBIG) and hepatitis B vaccine in China. Methods The screening rate and the prevalence of hepatitis B surface antigen (HBsAg) in 61 790 puerperants, and the administration of combined immunoprophylaxis in infants of HBsAg-positive mothers in Rugao City of Jiangsu Province from July 1, 2011 to June 30, 2016 were retrospectively analyzed. HBV infection status of infants born to HBV infected mothers was followed up after 7 months of age. HBsAg-positive infants and their mothers were followed up again for HBV markers in April 2018. Fisher's exact test and Cochran-Armitage trend test were used to statistically analyze the differences between groups and various years, respectively. Results All 61 790 puerperants were screened for HBsAg and the prenatal screen rate was 98.6% (60 937/61 790) with an increasing trend over time (χ2trend=750.908, P<0.001). HBsAg-positive puerperants accounted for 5.5% (3 397/61 790) with a decreasing trend over time (χ2trend=32.667, P<0.001). In total, 778 offspring (399 boys and 379 girls) of 759 HBsAg-positive mothers were followed up at (13.7±6.9) months of age, among which 751 (96.5%) were administered and 25 (3.2%) were probably administered standard combined immunoprophylaxis after birth, and the rest two (0.3%) were not. Fourteen infants (1.8%) were HBsAg positive and all born to mothers with positive hepatitis B e antigen (HBeAg). None of the 538 infants born to HBeAg-negative mothers was HBsAg-positive. HBsAg-positive rate in infants born since 2013 was lower than those in 2011 and 2012 (χ2trend=13.352, P=0.000 3). Eleven HBsAg-positive mothers and their children were followed up again 4–5 years later in April 2018. HBV DNA levels of all mothers were within the range of (7.34–28.2)×107 IU/ml except one case of spontaneous HBeAg seroconversion. One out of the 11 infected children also had HBeAg seroconversion. Phylogenetic analysis of HBV S gene showed that the 11 pairs of mothers and children were all infected with HBV of genotype C. Conclusions The implementation of charge-free HBIG and hepatitis B vaccine for newborns achieves fruitful results in Rugao city as the mother-to-infant transmission of HBV in the real-world had been further reduced to a similar level reported in literature survey.

Immediate-early genes (IEGs) have long been used to visualize neural activations induced by sensory and behavioral stimuli. Recent advances in imaging techniques have made it possible to use endogenous IEG signals to visualize and discriminate neural ensembles activated by multiple stimuli, and to map whole-brain-scale neural activation at single-neuron resolution. In addition, a collection of IEG-dependent molecular tools has been developed that can be used to complement the labeling of endogenous IEG genes and, especially, to manipulate activated neural ensembles in order to reveal the circuits and mechanisms underlying different behaviors. Here, we review these techniques and tools in terms of their utility in studying functional neural circuits. In addition, we provide an experimental strategy to measure the signal-to-noise ratio of IEG-dependent molecular tools, for evaluating their suitability for investigating relevant circuits and behaviors.
