A cross-sectional analysis of gender and psychological well-being among older Taiwanese adults.

Background: Psychological well-being (PWB) facilitates good health. Few studies have taken into consideration gender and how it can affect PWB within a sociocultural context. This study aims to determine if relationships between social, health, behavioral, and socioeconomic factors on PWB among older Taiwanese adults are affected by gender. Methods: Data were obtained from the 2016 Taiwan Mental Health Survey. A representative sample, of 2,286 individuals, was created using multistage proportional probability. Participants were interviewed at their homes using a structured questionnaire. Inclusion criteria were Taiwanese citizenship, age ≥ 55 years, and the ability to provide informed consent. Participants 65 years and above were selected for the study sample n = 1,533. An 18-item version of Ryff's PWB scale was used to determine PWB. The median value was used to categorize low and high PWB. Logistic regression analyses were used to examine predictors of PWB stratified by gender. Results: Chronic disease, unemployment, and financial dependence negatively impacted men's PWB. Satisfaction with living environment and family relationships positively impacted women's PWB. Unique characteristics of older men, women, and culture account for this. Conclusion: Gender-specific interventions aimed at promoting PWB in older adults are needed. Recommendations include educational programs, social support workshops, and community engagement initiatives.

Astrocytes control quiescent NSC reactivation via GPCR signaling-mediated F-actin remodeling.

The transitioning of neural stem cells (NSCs) between quiescent and proliferative states is fundamental for brain development and homeostasis. Defects in NSC reactivation are associated with neurodevelopmental disorders. Drosophila quiescent NSCs extend an actin-rich primary protrusion toward the neuropil. However, the function of the actin cytoskeleton during NSC reactivation is unknown. Here, we reveal the fine F-actin structures in the protrusions of quiescent NSCs by expansion and super-resolution microscopy. We show that F-actin polymerization promotes the nuclear translocation of Mrtf, a microcephaly-associated transcription factor, for NSC reactivation and brain development. F-actin polymerization is regulated by a signaling cascade composed of G-protein-coupled receptor (GPCR) Smog, G-protein αq subunit, Rho1 GTPase, and Diaphanous (Dia)/Formin during NSC reactivation. Further, astrocytes secrete a Smog ligand Fog to regulate Gαq-Rho1-Dia-mediated NSC reactivation. Together, we establish that the Smog-Gαq-Rho1 signaling axis derived from astrocytes, a NSC niche, regulates Dia-mediated F-actin dynamics in NSC reactivation.

Neurotransmitter classification from electron microscopy images at synaptic sites in Drosophila melanogaster.

High-resolution electron microscopy of nervous systems has enabled the reconstruction of synaptic connectomes. However, we do not know the synaptic sign for each connection (i.e., whether a connection is excitatory or inhibitory), which is implied by the released transmitter. We demonstrate that artificial neural networks can predict transmitter types for presynapses from electron micrographs: a network trained to predict six transmitters (acetylcholine, glutamate, GABA, serotonin, dopamine, octopamine) achieves an accuracy of 87% for individual synapses, 94% for neurons, and 91% for known cell types across a D. melanogaster whole brain. We visualize the ultrastructural features used for prediction, discovering subtle but significant differences between transmitter phenotypes. We also analyze transmitter distributions across the brain and find that neurons that develop together largely express only one fast-acting transmitter (acetylcholine, glutamate, or GABA). We hope that our publicly available predictions act as an accelerant for neuroscientific hypothesis generation for the fly.

[Mechanism and application prospects of microbial fertilizers in regulating quality formation of medicinal plants].

With the promotion of chemical fertilizer and pesticide reduction and green production of traditional Chinese medicines, microbial fertilizers have become a hot way to achieve the zero-growth of chemical fertilizers and pesticides, improve the yield and qua-lity of medicinal plants, maintain soil health, and promote the sustainable development of the planting industry of Chinese herbal medicines. Soil conditions and microenvironments are crucial to the growth, development, and quality formation of medicinal plants. Microbial fertilizers, as environmentally friendly fertilizers acting on the soil, can improve soil quality by replenishing organic matter and promoting the metabolism of beneficial microorganisms to improve the yield and quality of medicinal plants. In this regard, understanding the mechanism of microbial fertilizer in regulating the quality formation of medicinal plants is crucial for the development of herbal eco-agriculture. This study introduces the processes of microbial fertilizers in improving soil properties, participating in soil nutrient cycling, enhancing the resistance of medicinal plants, and promoting the accumulation of medicinal components to summarize the mechanisms and roles of bacterial fertilizers in regulating the quality formation of medicinal plants. Furthermore, this paper introduces the application of bacterial fertilizers in medicinal plants and makes an outlook on their development, with a view to providing a scientific basis for using microbial fertilizers to improve the quality of Chinese herbal medicines, improve the soil environment, promote the sustainable development of eco-agriculture of traditional Chinese medicine, and popularize the application of microbial fertilizers.

Astaxanthin alleviates chronic prostatitis/chronic pelvic pain syndrome by increasing colonization of Akkermansia muciniphila in the intestine.

BACKGROUND: Astaxanthin (AST) is a natural compound with anti-inflammatory/immunomodulatory properties that has been found to have probiotic properties. However, the role and mechanism of AST in chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) are still not fully understood. PURPOSE: The aim of this study was to evaluate the effect of AST on CP/CPPS and elucidate the mediating role of the gut microbiota. MATERIALS AND METHODS: An experimental autoimmune prostatitis (EAP) mouse model was utilized to test the potential role of AST on CP/CPPS. Antibiotic cocktail (ABX) treatment and fecal microbiota transplantation (FMT) were used to elucidate the gut microbiota-mediated effects on AST. In addition, 16S rRNA gene sequencing and qRT-PCR analyses were used to analyze changes in the gut microbiota of EAP mice and CP/CPPS patients. Finally, the mechanism by which AST exerts a protective effect on CP/CPPS was explored by untargeted metabolomics and gut barrier function assays. RESULTS: Oral administration of AST reduced prostate inflammation scores, alleviated tactile sensitization of the pelvic region in EAP mice, reduced CD4+ T cell and CD68+ macrophage infiltration in the prostatic interstitium, and inhibited the up-regulation of systemic and localized pain/pro-inflammatory mediators in the prostate. After ABX, the protective effect of AST against CP/CPPS was attenuated, whereas colonization with fecal bacteria from AST-treated EAP mice alleviated CP/CPPS. 16S rRNA gene sequencing and qRT-PCR analyses showed that Akkermansia muciniphila in the feces of EAP mice and CP/CPPS patients showed a trend toward a decrease, which was associated with poor progression of CP/CPPS. In contrast, oral administration of AST increased the relative abundance of A. muciniphila, and oral supplementation with A. muciniphila also alleviated inflammation and pain in EAP mice. Finally, we demonstrated that both AST and A. muciniphila interventions increased serum levels of SCFAs acetate, up-regulated expression of colonic tight junction markers, and decreased serum lipopolysaccharide levels in EAP mice. CONCLUSION: Our results showed that AST improved CP/CPPS by up-regulating A. muciniphila, which provides new potentially effective strategies and ideas for CP/CPPS management.

Research progress in micro/nanobubbles for ultrasound diagnosis or treatment / 药学学报

In the past few decades, microbubbles were widely used as ultrasound contrast agents in the field of tumor imaging. With the development of research, ultrasound targeted microbubble destruction technology combined with drug-loaded microbubbles can achieve precise drug release and play a therapeutic role. As a micron-scale carrier, microbubbles are difficult to penetrate the endothelial cell space of tumors, and nano-scale drug delivery system—nanobubbles came into being. The structure of the two is similar, but the difference in size highlights the unique advantages of nanobubbles in drug delivery. Based on the classification principle of shell materials, this review summarized micro/nanobubbles used for ultrasound diagnosis or treatment and discussed the possible development directions, providing references for the subsequent development.

CONCLUSIONS Advanced age， liver insufficiency， renal insufficiency， complicated with malignant tumors and hypoalbuminemia， combined use of anticoagulant drugs， poor diet， daily dose ≥9 g， and medication duration≥10 days are risk factors for coagulation dysfunction caused by cefoperazone/sulbactam.

Effects of social capital on healthcare utilization among older adults in Indonesia.

Social capital potentially affects older adults' access to healthcare services. However, the effects of social capital on the use of various types of healthcare services using longitudinal data have yet to be explored. This study aimed to examine the effects of structural and cognitive social capital on different types of healthcare utilization by older adults in Indonesia. Data were from the Indonesian Family Life Survey (waves 4 and 5) in 2007 and 2014. The sample consisted of participants aged 60 years and older who completed both waves (n = 1374). Healthcare utilization by older adults assessed health posts (posyandu), health checkups, outpatient care and hospital admissions. Social capital consisted of neighborhood trust and community participation. Generalized estimating equation models were used for the analysis. Older adults with high community participation had a higher likelihood of using preventive care in posyandu (OR = 5.848, 95% CI = 2.585-13.232) and health checkup visits (OR = 1.621, 95% CI = 1.116-2.356). Meanwhile, neighborhood trust was related to a higher probability of hospital admissions (OR = 1.255, 95% CI = 1.046-1.505). Social capital significantly affects older adults' preventive and treatment healthcare utilization. Maximizing the availability of social participation and removing barriers to access to preventive and medical care in an age-friendly environment are suggested.

Golgi-dependent reactivation and regeneration of Drosophila quiescent neural stem cells.

The ability of stem cells to switch between quiescent and proliferative states is crucial for maintaining tissue homeostasis and regeneration. In Drosophila, quiescent neural stem cells (qNSCs) extend a primary protrusion, a hallmark of qNSCs. Here, we have found that qNSC protrusions can be regenerated upon injury. This regeneration process relies on the Golgi apparatus that acts as the major acentrosomal microtubule-organizing center in qNSCs. A Golgi-resident GTPase Arf1 and its guanine nucleotide exchange factor Sec71 promote NSC reactivation and regeneration via the regulation of microtubule growth. Arf1 physically associates with its new effector mini spindles (Msps)/XMAP215, a microtubule polymerase. Finally, Arf1 functions upstream of Msps to target the cell adhesion molecule E-cadherin to NSC-neuropil contact sites during NSC reactivation. Our findings have established Drosophila qNSCs as a regeneration model and identified Arf1/Sec71-Msps pathway in the regulation of microtubule growth and NSC reactivation.

Sulfosuccinimidyl oleate ameliorates the high-fat diet-induced obesity syndrome by reducing intestinal and hepatic absorption.

Background: A high-fat Western diet is a risk factor for obesity and steatosis. Reducing intestinal absorption of a high-fat diet (HFD) is a feasible strategy to control obesity. Sulfosuccinimidyl oleate (SSO) inhibits intestinal fatty acid transport. Therefore, the aim of this study was to investigate the effects of SSO on HFD-induced glucose and lipid metabolism in mice and its possible underlying mechanisms. Methods: Male C57/BL were fed a HFD (60% calories) for 12 weeks and were administered an oral dose of SSO (50 mg/kg/day). The expression of lipid absorption genes (CD36, MTTP, and DGAT1) and the serum levels of triglycerides (TGs), total cholesterol (TC), and free fatty acids (FFAs) were detected. Lipid distribution in the liver was detected by oil red and hematoxylin and eosin staining. In addition, serum levels of inflammatory factors, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were measured to detect side effects. Results: SSO was effective in the treatment of obesity and metabolic syndrome induced by HFD in mice. It attenuated the assembly of intestinal epithelial chylomicrons by inhibiting intestinal epithelial transport and absorption of fatty acids, thereby reducing the gene expression levels of MTTP and DGAT1, resulting in decreased plasma TG and FFA levels. At the same time, it inhibited the transport of fatty acids in the liver and improved the steatosis induced by a HFD. The results of oil red staining showed that SSO treatment can reduce lipid accumulation in the liver by 70%, with no drug-induced liver injury detected on the basis of interleukin-6, C-reactive protein, ALT, and AST levels. In addition, SSO treatment significantly improved insulin resistance, decreased fasting blood glucose levels, and improved glucose tolerance in HFD-fed mice. Conclusion: SSO is effective in the treatment of obesity and metabolic syndrome induced by a HFD in mice. SSO reduces intestinal fatty acid absorption by reducing the inhibition of intestinal CD36 expression, followed by decreased TG and FFA levels, which attenuates HFD-induced fatty liver.

Family economic trajectories and body mass index in Indonesia: Evidence from the Indonesian Family Life Surveys 2 to 5.

Indonesia faces the double burdens of childhood obesity and malnutrition. A family's socioeconomic status has been suggested to be one of the most influential factors contributing to childhood nutritional problems. This study aimed to: 1) identify the distinct trajectories of family economics; and 2) assess whether a family's economic trajectory influences children's body mass index (BMI). We analyzed trajectory patterns of family economic levels from 1997 to 2015 among 846 children aged under 3 years in 1997 using data from Indonesian Family Life Surveys. Trajectory patterns were identified with Group-Based Trajectory Modeling using the traj plug-in in STATA software. The BMI was classified according to 2007 World Health Organization growth standards. Adjusted relative risk ratios (aRRRs) of family economic level trajectories and children's BMI were calculated using multinomial logistic regressions. We identified three distinct trajectories of family economic level: stable poorest, stable middle, and increasing richest. In the total sample, there were no significant relationships between a family's income trajectory and children's BMI in the adjusted models. A significant relationship existed for male children, but not for female children, of compared to the poorest family trajectory group, male children in the increasing richest trajectory group were more likely to be overweight/obese (aRRR 6.1, 95% confidence interval: 1.22-30.62) after adjusting for age and BMI. The present results highlight the importance of early interventions to minimize the potential adverse impacts of excessive BMI later in adulthood.

Prevalence of and Factors Associated with Depressive Symptoms among Indonesian Migrant Workers in Taiwan.

International migrant workers contribute significantly to the economic growth of the receiving country, and yet their health, especially their mental health, has long been overlooked. The purpose of this study was to identify the factors associated with depressive symptoms among Indonesian migrant workers in Taiwan. This study used cross-sectional data from 1031 Indonesian migrant workers in Taiwan. Demographic, health, and living- and work-related variables, as well as depressive symptom variables assessed using the Center for Epidemiological Study on depressive symptoms scale, were collected. Logistic regression analysis was used to identify related factors. About 15% of the Indonesian migrant workers had depressive symptoms. The significant factors associated with these symptoms were age, educational level, frequency of contact with families, self-rated health, time spent in Taiwan, region of work, satisfaction with the living environment, and freedom to go out after work. The findings thus identify target groups who are more likely than others to suffer from depressive symptoms, and we suggest appropriate approaches for devising interventions to reduce depressive symptoms. The findings of this research suggest the need for targeted approaches to reducing depressive symptoms among this population group.

Overexpression of SlGGP-LIKE gene enhanced the resistance of tomato to salt stress.

Ascorbic acid (AsA) plays an important role in scavenging reactive oxygen species (ROS) and reducing photoinhibition in plants, especially under stress. The function of SlGGP which encodes the key enzyme GDP-L-galactose phosphorylase in AsA synthetic pathway is relatively clear. However, there is another gene SlGGP-LIKE that encodes this enzyme in tomato, and there are few studies on it, especially under salt stress. In this study, we explored the function of this gene in tomato salt stress response using transgenic lines overexpressing SlGGP-LIKE (OE). Under normal conditions, overexpressing SlGGP-LIKE can increase the content of reduced AsA and the ratio of AsA/ DHA (dehydroascorbic acid), as well as the level of xanthophyll cycle. Under salt stress, compared with the wild-type plants (WT), the OE lines can maintain higher levels of reduced AsA. In addition, OE lines also have higher levels of reduced GSH (glutathione) and total GSH, higher ratios of AsA/DHA and GSH/oxidative GSH (GSSR), and higher level of xanthophyll cycle. Therefore, the OE lines are more tolerant to salt stress, with higher photosynthetic activity, higher antioxidative enzyme activities, higher content of D1 protein, lower production rate of ROS, and lighter membrane damage. These results indicate that overexpressing SlGGP-LIKE can enhance tomato resistance to salt stress through promoting the synthesis of AsA.

The role of Xpert MTB/RIF using bronchoalveolar lavage fluid in active screening: insights from a tuberculosis outbreak in a junior school in eastern China.

Background: Tuberculosis (TB) outbreaks in schools present a public health challenge. In order to effectively control the spread of transmission, timely screening, accurate diagnosis and comprehensive epidemiological investigations are essential. Methods: In July 2021, a TB outbreak occurred in a junior high school in Y City, Zhejiang Province. Students and faculty were screened for TB by symptom screening, chest radiography, and tuberculin skin test during four rounds of contact screenings. For sputum smear-negative and sputum-scarce patients, bronchoscopy was used to collect BAL samples for Xpert Mycobacterium tuberculosis/rifampin (MTB/RIF). Whole-genome sequencing and bioinformatics analysis were performed on isolates to identify the strains of MTB isolates and predict drug resistance. Results: Between July 2021 and November 2021, a total of 1,257 students and faculty were screened for TB during screenings. A total of 15 students (1.2% of persons screened) aged 15 years were diagnosed with TB. Eighty percent (12/15) of the cases were laboratory-confirmed (10/12 [83%] Xpert MTB/RIF-positive, 2/12 [17%] culture-positive). Most cases (12/15 [80%]) were in students from Class 2. All cases were asymptomatic except for the index case who had symptoms for more than two months. Seven MTB isolates were collected and belonged to lineage 2. Conclusion: Our findings demonstrated the potential of Xpert MTB/RIF using BAL as a screening tool in school TB outbreaks for sputum smear-negative and sputum-sparse suspects, which may not only rapidly improves diagnostic accuracy, but also facilitates epidemiological investigations and homology analysis.

Overview of systematic reviews of Chinese herbal injections for sepsis / 中国中药杂志

In this study, an overview of systematic reviews/Meta-analysis(SR/MA) of Chinese herbal injections for sepsis was performed to provide references for clinical practice and promote the quality improvement of clinical evidence. Eight Chinese and English databases such as CNKI, Medline, and EMbase were electronically searched for SR/MA of Chinese herbal injections for sepsis from database inception to June 2022. AMSTAR 2, PRISMA 2020, and GRADE system, combined with Recommendations for Clinical Evidence Grading on Traditional Chinese Medicine Based on Evidence Body, were applied to evaluate the methodological quality, reporting quality, and evidence quality of the included articles. Twenty-seven articles of SR/MA were included, containing four Chinese herbal injections(Xuebijing Injection, Shenfu Injection, Shenmai Injection, and Shengmai Injection). AMSTAR 2 checklist showed that the methodological quality of the SR/MA ranged from moderate to very low. Item 2(prior study design) was the critical item with poor scores, and the non-critical items with poor scores were items 3(explain the selection of the study designs), items 10(report on the sources of funding), and items 16(conflicts of interest stated). In terms of PRISMA 2020, items in eight topics with complete reporting of missing>50%, including search strategy, certainty assessment, results of syntheses, certainty of evidence, registration and protocol, support, competing interests, availability of data, code and other materials. The included SR/MA involved 30 outcome indicators. Evidence quality of mortality, APACHE Ⅱ, and safety, the top three outcome indicators, was evaluated, and all of them were graded as the medium level. The lack of random allocation sequence, allocation concealment mechanism, blinding, and trial sample size was the main reason for the reduction of the evidence level. The available evidence shows that Chinese herbal injections can serve as an effective and safe adjunctive treatment for sepsis, which can reduce mortality, inhibit inflammation, improve coagulation function, and regulate immune function, tissue perfusion, and oxygenation in patients with sepsis. However, the quality of SR/MA was suboptimal, and more high-quality SR/MA is needed to provide evidence to support the efficacy and safety of Chinese herbal injections in the treatment of sepsis.

BACKGROUND@#The results of studies comparing Billroth-I (B-I) with Roux-en-Y (R-Y) reconstruction on the quality of life (QoL) are still inconsistent. The aim of this trial was to compare the long-term QoL of B-I with R-Y anastomosis after curative distal gastrectomy for gastric cancer.@*METHODS@#A total of 140 patients undergoing curative distal gastrectomy with D2 lymphadenectomy in West China Hospital, Sichuan University from May 2011 to May 2014 were randomly assigned to the B-I group ( N  = 70) and R-Y group ( N  = 70). The follow-up time points were 1, 3, 6, 9, 12, 24, 36, 48, and 60 months after the operation. The final follow-up time was May 2019. The clinicopathological features, operative safety, postoperative recovery, long-term survival as well as QoL were compared, among which QoL score was the primary outcome. An intention-to-treat analysis was applied.@*RESULTS@#The baseline characteristics were comparable between the two groups. There were no statistically significant differences in terms of postoperative morbidity and mortality rates, and postoperative recovery between the two groups. Less estimated blood loss and shorter surgical duration were found in the B-I group. There were no statistically significant differences in 5-year overall survival (79% [55/70] of the B-I group vs. 80% [56/70] of the R-Y group, P  = 0.966) and recurrence-free survival rates (79% [55/70] of the B-I group vs. 78% [55/70] of the R-Y group, P  = 0.979) between the two groups. The scores of the global health status of the R-Y group were higher than those of the B-I group with statistically significant differences (postoperative 1 year: 85.4 ± 13.1 vs . 88.8 ± 16.1, P  = 0.033; postoperative 3 year: 87.3 ± 15.2 vs . 92.8 ± 11.3, P  = 0.028; postoperative 5 year: 90.9 ± 13.7 vs . 96.4 ± 5.6, P  = 0.010), and the reflux (postoperative 3 year: 8.8 ± 12.9 vs . 2.8 ± 5.3, P  = 0.001; postoperative 5 year: 5.1 ± 9.8 vs . 1.8 ± 4.7, P  = 0.033) and epigastric pain (postoperative 1 year: 11.8 ± 12.7 vs. 6.1 ± 8.8, P  = 0.008; postoperative 3 year: 9.4 ± 10.6 vs. 4.6 ± 7.9, P  = 0.006; postoperative 5 year: 6.0 ± 8.9 vs . 2.7 ± 4.6, P  = 0.022) were milder in the R-Y group than those of the B-I group at the postoperative 1, 3, and 5-year time points.@*CONCLUSIONS@#Compared with B-I group, R-Y reconstruction was associated with better long-term QoL by reducing reflux and epigastric pain, without changing survival outcomes.@*TRIAL REGISTRATION@#ChiCTR.org.cn, ChiCTR-TRC-10001434.

Agreement study of anterior segment parameters measured by two kinds of ocular biometry based on imaging principle of Scheimpflug / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To compare the differences and agreement of anterior segment biometric parameters of myopic patients measured by domestic Scansys and the imported Sirius based on the principle of Scheimpflug imaging technique.METHODS: In this case series study, 103 cases(103 eyes)that underwent pre-refractive surgery(including small incision lenticule extraction, femtosecond laser-assisted in situ keratomileusis, transepithelial photorefractive keratectomy and implantable contact lens implantation)at Aier Excellent Eye Hospital from May 2022 to October 2022 were recruited. Preoperative keratometry(Km), central corneal thickness(CCT), anterior chamber depth(ACDEndo.), anterior chamber angle(ACA), anterior chamber volume(ACV), white to white(WTW)of patients were recorded.RESULTS: The results of Km, CCT, ACA, and WTW measured by Scansys and Sirius were 42.88(41.54, 44.60)and 42.98(41.56, 44.52)D,(541.52±29.08)and(549.55±29.62)μm, 42.70°±2.67° and 46.63°±5.13°, 12.10±0.60 and 11.98±0.47 mm, respectively, showing the difference was statistically significant(all P<0.01). The ACV measured by Scansys and Sirius was 194.26±31.06 and 191.47±25.65 mm3, and ACDEndo. was 3.40(3.17, 3.57)and 3.43(3.19, 3.56)mm, with no statistically significant difference(all P>0.05). The range of Km, CCT, ACA, ACDEndo., ACV and WTW values measured by the two instruments was small, with an average difference close to zero, and the points percentage of 95% limits of agreement(LoA)was <5%, which is of good consistency.CONCLUSIONS: Scansys and Sirius have small differences and good agreement in the parameters, which can be replaced by each other in clinical practice. Scansys could theoretically be used to extrapolate the implantable contact lens model or could be a new option for anterior segment parameter measurements.

Consistency between modified 12+ X prostate biopsy and systematic biopsy under transrectal interventional ultrasound and Gleason score after prostate cancer surgery / 中国医师杂志

Objective:To explore the consistency between modified 12+ X prostate biopsy under transrectal interventional ultrasound and postoperative Gleason score in prostate cancer patients.Methods:A retrospective study was conducted on 312 patients diagnosed with prostate cancer and underwent radical resection at Zhongshan People′s Hospital from January 2020 to December 2022. All patients underwent modified 12+ X prostate biopsy and prostate system biopsy under transrectal interventional ultrasound before surgery. Using the Gleason score of postoperative pathological specimens as the " gold standard", the detection rates of prostate cancer and clinically significant prostate cancer using modified 12+ X prostate biopsy and prostate system biopsy under transrectal interventional ultrasound were compared, and the consistency between the two methods alone or in combination and postoperative Gleason score was compared.Results:Among 312 patients, the positive detection rate of the improved 12+ X puncture biopsy combined with the system puncture biopsy was significantly higher than that of the individual detection (95.51% vs 80.77% vs 76.92%), with a statistically significant difference ( P<0.05). The improved 12+ X puncture biopsy combined with system puncture biopsy showed a clinically significant higher detection rate of prostate cancer in positive patients compared to the two tests alone (94.63% vs 77.78% vs 80.00%), with a statistically significant difference ( P<0.05). There was no statistically significant difference in the detection rate of clinically significant prostate cancer among patients who missed diagnosis, either alone or in combination with biopsy ( P>0.05). The upgrade rate of Gleason score after prostate improvement 12+ X puncture biopsy (25.00%) was significantly lower than that of prostate system puncture (44.17%), which was significantly higher than combined puncture biopsy (11.74%), with a statistically significant difference ( P<0.05). After 312 patients received combined puncture biopsy, urinary retention was found in 14 cases (4.49%), hematuria in 30 cases (9.62%), fever in 28 cases (8.97%), and blood in stool in 18 cases (5.77%). After symptomatic treatment, they basically improved within 3 days after puncture. Conclusions:The combination of modified 12+ X prostate biopsy with systematic biopsy under transrectal interventional ultrasound can improve the detection rate of prostate cancer, and has good consistency with the postoperative Gleason score of prostate cancer patients, which has good clinical application value.

The expression of adhesion molecules in Z310 cells induced by combined exposure to black carbon and lead / 中国职业医学

Objective: To investigate the effects of combined exposure to black carbon and lead on the expression of cell adhesion molecules and their regulating microRNAs (miRNAs) in the rat choroid plexus epithelial Z310 cells. Methods: i) Z310 cells were randomly divided into control group, black carbon exposure group, lead exposure group and combined exposure group. The lead exposure group and black carbon exposure group were treated with 10 μmol/L lead acetate and 10 mg/L black carbon, respectively, and the combined exposure group was treated with both in the above doses. After 12.0 hours, the expressions of intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and mucosal vascular addressin cell adhesion molecule-1 (MAdCAM-1) in Z310 cells was detected by Western blotting. The expression of miR-326, miR-328-3p and miR-542-3p which regulated ICAM-1 was detected by real-time fluorescent quantitative polymerase chain reaction. ii) Z310 cells or Z310 cells transfected with miRNA-326 mimic were randomly divided into control group, miRNA-326 transfection control group, combined exposure group and miRNA-326 transfection combined exposure group. Cells in the two control groups were not treated. The two combined exposure groups were treated with 10 mg/L black carbon and 10 μmol/L lead acetate for 12.0 hours. The expression of ICAM-1 was detected by Western blotting. Results: i) The relative expression of ICAM-1, VCAM-1 and MAdCAM-1 in the cells of black carbon exposure group and ICAM-1 in the lead exposure group was higher than those in the control group (all P<0.05). The relative expression of ICAM-1 and MAdCAM-1 in the combined exposure group was higher than those in the other three groups (all P<0.05). The relative expression of VCAM-1 in cells of combined exposure group was higher than those in the control group and lead exposed group (all P<0.05). The relative expression of miR-326 in cells of the lead exposure group and black carbon exposure group was lower than those in the control group (all P<0.05). The relative expression of miR-326 in the combined exposure group was lower than that in the other three groups (all P<0.05). There was no significant difference between miR-328-3p and miR-542-3p in the four groups (all P>0.05). ii) The relative expression of ICAM-1 in cells of the miR-326 transfection control group cells was lower than that in the control group (P<0.05), while in the cells in the combined exposure and miRNA-326 transfection combined exposure group, it was higher than that in the control and miRNA-326 transfection control groups (all P<0.05), and lower in the miRNA-326 transfection combined exposure group than in the combined exposure group (P<0.05). Conclusion: Black carbon or lead exposure can upregulate the expression of ICAM-1, VCAM-1 and MAdCAM-1 in Z310 cells. Black carbon and lead combined exposure lead to a synergistic effect on upregulation of ICAM-1 and MAdCAM-1 expression, particularly ICAM-1. The combined exposure of black carbon and lead may upregulate the expression of ICAM-1 by downregulating the expression of miR-326.
