RESUMO

OBJECTIVE@#To assess the risk of aristolochic acid (AA)-associated cancer in patients with AA nephropathy (AAN).@*METHODS@#A retrospective study was conducted on patients diagnosed with AAN at Peking University First Hospital from January 1997 to December 2014. Long-term surveillance and follow-up data were analyzed to investigate the influence of different factors on the prevalence of cancer. The primary endpoint was the incidence of liver cancer, and the secondary endpoint was the incidence of urinary cancer during 1 year after taking AA-containing medication to 2014.@*RESULTS@#A total of 337 patients diagnosed with AAN were included in this study. From the initiation of taking AA to the termination of follow-up, 39 patients were diagnosed with cancer. No cases of liver cancer were observed throughout the entire follow-up period, with urinary cancer being the predominant type (34/39, 87.17%). Logistic regression analysis showed that age, follow-up period, and diabetes were potential risk factors, however, the dosage of the drug was not significantly associated with urinary cancer.@*CONCLUSIONS@#No cases of liver cancer were observed at the end of follow-up. However, a high prevalence of urinary cancer was observed in AAN patients. Establishing a direct causality between AA and HCC is challenging.

RESUMO

ObjectiveUsing the liquid chromatography-tandem mass spectrometry (LC-MS/MS) to determine the plasma level of Lyso-GL3 in patients with Fabry disease and to analyze the clinical application of the method.MethodsThirty-nine patients with a genetic diagnosis of Fabry disease were included, and plasma levels of Lyso-GL3 were measured by LC-MS/MS analysis, and detailed clinical information of the patients was obtained including: α-galactosidase A activity, genetic variants, quantification of urine protein, mean arterial pressure, and estimation of glomerular filtration rate, and the differences in the levels of Lyso-GL3 in different clinical phenotypes and genotypes were statistically analyzed, as well as the association with clinical indicators.ResultsLyso-GL3 showed good linearity within 0.7856-400 ng/mL(r=0.9992).Further analysis of 39 Fabry disease patients diagnosed in Ruijin Hospital, Shanghai Jiao Tong University School of Medicine showed a median Lyso-GL3 concentration of 23.6 ng/mL(4.3-92.9 ng/mL); Lyso-GL3 levels were significantly higher in patients with both the frameshift and the splicing mutations, as well as in patients with the nonsense mutations, than in patients with the missense mutations (median value 119.7 ng/mL vs. 11.9 ng/mL, P=0.006, and median value 97.0 ng/mL vs. 11.9 ng/mL, P=0.015, respectively). Whereas, association analysis revealed that Lyso-GL3 was not significantly associated with urinary protein, mean arterial pressure and estimated glomerular filtration rate.ConclusionsThe using of LC-MS/MS to quantify plasma Lyso-GL showed significant differences in Lyso-GL3 concentrations between classical and atypical phenotypes, suggesting that plasma Lyso-GL3 may help with clinical phenotypes. However, Lyso-GL3 levels is found to be overlapped between genotypes. No significant linear correlation was found between Lyso-GL3 and renal clinical indicators, suggesting the urgent need in finding a more accurate tool to assess renal involvement and prognosis in patients with Fabry disease.

RESUMO

With the changes in various factors such as genetics and the environment, the incidence of childhood precocious puberty has been gradually increasing. Improving height is one of the key issues in the clinical management of precocious puberty. Currently, gonadotropin-releasing hormone analogs (GnRHa) remain the preferred treatment for precocious puberty, but their effect on height improvement is influenced by multiple factors, which may result in lower-than-expected height benefits. Combining recombinant human growth hormone (rhGH) therapy with GnRHa treatment is an alternative strategy to enhance the efficacy of GnRHa, but there is still no clear recommendation regarding the timing of their combination. Considering the current status of precocious puberty treatment, it is crucial to reevaluate the effects of GnRHa monotherapy and combination therapy with rhGH on height improvement. This article discusses strategies such as combination therapy indications to guide clinical medication and help children with precocious puberty achieve optimal height benefits.

RESUMO

Non-alcoholic fatty liver disease (NAFLD) is considered to be a manifestation of metabolic syndrome and has become one of the chronic diseases that endanger health around the world. There is still a lack of effective therapeutic drugs in clinical practice. Farnesoid X receptor (FXR) has been a popular target for NAFLD research in recent years. Fexaramine (Fex) is a potent and selective agonist of FXR, and its mechanism of action to improve NAFLD is unclear. Therefore, in this study, a mouse model of NAFLD was constructed using a high-fat, high-cholesterol diet and treated with Fex orally for 6 weeks. We evaluated the ameliorative effect of Fex on disorders of glucolipid metabolism in NAFLD mice, and preliminarily explored its potential mechanism of action. The animal experiments were approved by the Animal Ethics Committee of Shanghai University of Traditional Chinese Medicine (approval number: PZSHUTCM210913011). In this study, it was found that 100 mg·kg-1 Fex significantly inhibited body weight gain, alleviated insulin resistance, improved liver injury and lipid accumulation in NAFLD mice. The effect of Fex on the expression of hepatic intestinal FXR and its target genes in NAFLD mice was further examined. Analysis of serum and hepatic bile acid profiles and expression related to hepatic lipid metabolism. It was found that Fex could stimulate intestinal FXR, promote fibroblast growth factor 15 (FGF15) secretion, inhibit the expression of cytochrome P450 family 7 subfamily A member 1 (CYP7A1), the rate-limiting enzyme of bile acid synthesis in liver, regulate bile acid synthesis by negative feedback, and improve the disorder of bile acid metabolism. At the same time, Fex reduces liver lipid synthesis and absorption, increases fatty acid oxidation, thus improving liver lipid metabolism. This study shows that Fex can improve NAFLD by activating intestinal FXR-FGF15 signal pathway and regulating liver lipid metabolism.

RESUMO

The "toxicity" and safety of traditional Chinese medicines have been seriously concerned. Alkaloids are the main pharmacodynamic components of many kinds of traditional Chinese medicines, which show strong biological activity at low concentration. It will also cause toxic side effects but if used improperly. Some alkaloids are both active and toxic, and the safety of related traditional Chinese medicines is particularly noteworthy. The efficacy or toxicity of alkaloids may be the result of the combined action of parent compounds and metabolites, which is not only related to the structural types of compounds, but also has obvious species differences between humans and animals. This review focused on the alkaloids contained in the "toxic" traditional Chinese medicines that are officially recorded in Chinese Pharmacopoeia and the metabolism patterns of alkaloids with different structures as well as the enzymes involved were summarized and discussed by referencing the publications in recent two decades. The present study will be beneficial to the rational use of these traditional Chinese medicines in clinic.

RESUMO

Sophorae Flavescentis Radix is the dried root of Sophora flavescens Ait. and Sophorae Tonkinensis Radix et Rhizoma is the dried root and rhizome of Sophora tonkinensis Gagnep. The two drugs are both from the same genus Sophora, having similar and different compositions and efficacies, however, their differences are not fully demonstrated in current standard. In this study, the high-performance thin-layer chromatography with multi-dimensional and multi-level features combined with electric spray mass spectrometry (HPTLC-ESI-MS) was used to discover and identify the characteristic zones in extracts of Sophorae Flavescentis Radix and Sophorae Tonkinensis Radix et Rhizoma, after optimizing the preparation method of the test solution and chromatographic parameters. As a result, 17 main characteristic zones were found on HPTLC chromatograms of Sophorae Flavescentis Radix and Sophorae Tonkinensis Radix et Rhizoma, among them, besides 3 known chemicals, another 12 unknown components were identified by HPTLC-ESI-MS, they are 1 alkaloid and 11 flavonoids. The identification results were verified by the reference standards partially and nuclear magnetic resonance spectra after guided-isolation. Finally, a unified HPTLC specific identification method with different markers was established to identify Sophorae Flavescentis Radix and Sophorae Tonkinensis Radix et Rhizoma simultaneously. Thanks to abundant chemical information provided when using diverse polarity mobile phases and derivatization reagents, the HPTLC technology offers a convenient strategy for discovery, quality evaluation, and identification of target chemicals when connecting with mass spectrometry.

RESUMO

OBJECTIVE To explore the risk signal of ixazomib and provide a reference for clinically rational drug use. METHODS The Open Vigil 2.1 online tool was used to extract the data of adverse drug events (ADE) reported by the database of FDA adverse event reporting system (FAERS) from the launch of ixazomib in America (November 20th, 2015) to the latest update of the Open Vigil website (March 31st, 2023). The data were mined by using the proportional reporting ratio (PRR) and Bayesian confidence propagation neural network (BCPNN) of the proportional imbalance method. The signals were coded by system organ class (SOC) and preferred term (PT) according to MedDRA v25.1. RESULTS A total of 13 841 ADE reports with ixazomib as the “primary subject” were extracted, involving slightly more male patients (49.53%), and most of them were 65 years old and above (72.48%); the reports came from 57 countries/regions, mainly America (52.90%). A total of 186 positive signals were excavated, with 51 high-intensity, 99 medium-intensity, and 36 low-intensity signals, involving 19 SOCs. The top 50 PT in frequency and signal intensity of PRR included neuropathy peripheral (414 cases, high-intensity signal), platelet count decreased (379 cases, high-intensity signal), thrombocytopenia (360 cases, high-intensity signal), cytopenia (75 cases, high-intensity signal) and neurological symptoms (41 cases, high-intensity signal). SOC involved included nervous system disorders, investigations, and blood and lymphatic system disorders. ADE occurred most frequently in gastrointestinal diseases (2 588 cases), including diarrhea (1 077 cases, high-intensity signal), nausea (737 cases, medium-intensity signal), vomiting (459 cases, medium-intensity signal), constipation (275 cases, medium-intensity signal), and so on. The positive signals of infections and infestations contained the largest number of PTs, and most of them were not recorded in the drug instruction, including 12 high-intensity signals (1 030 cases) and 30 medium-intensity signals (627 cases), which were mainly distributed in lung infection, upper respiratory infection, gastrointestinal infection, sepsis, herpes zoster and so on. The signals of cardiac amyloidosis (7 cases, high-intensity signal) and acute coronary syndrome (14 cases, high-intensity signal) of cardiac disorders and renal dysfunction (91 cases, medium-intensity signal) of renal and urinary disorders were all strong and had not been recorded in the drug instruction. CONCLUSIONS In addition to routine attention to the common ADE of ixazomib in gastrointestinal diseases,nervous system disorders and blood and lymphatic system disorders, clinical attention should also be paid to various infections that may occur during the treatment of patients, and the occurrence of cardiovascular toxicity and renal dysfunction should be monitored.

RESUMO

AIM:To explore the effect of genetic factors on the pathogenesis of keratoconus and its genetic model.METHODS: Genetic epidemiological methods were used to investigate the prevalence of keratoconus in 280 first-degree relatives of 100 patients with keratoconus who attended Henan Eye Hospital between July 2020 and April 2023. The heritability was estimated by Falconer regression method. The general genetic model was calculated using Penrose method, and the genetic model was confirmed by Falconer formula, Edwards approximation formula and the projection formula of San-Duo Jiang's threshold model theory.RESULTS: The results showed that there were 16(5.714%)first-degree relatives of keratoconus probands suffering from keratoconus, and the heritability of keratoconus was(86.100±7.400)%. The S/q score calculated by the Penrose method was 35.348, which was near to 1/(q)1/2, suggesting that the genetic model of keratoconus might be polygenic inheritance. The expected prevalence in first-degree relatives of keratoconus patients by Falconer formula, Edwards approximation formula and the projection formula of San-Duo Jiang's threshold model theory were 5.900%, 7.714% and 5.700%, respectively, which showed no significant differences from the actual prevalence(5.714%), suggesting that keratoconus was a polygenetic disease.CONCLUSION:Genetic factors might play an important role in the pathogenesis of keratoconus, and keratoconus is a polygenetic disease.

RESUMO

BACKGROUND@#The benefits of healthy lifestyles are well recognized. However, the extent to which improving unhealthy lifestyles reduces cardiovascular disease (CVD) risk needs to be discussed. We evaluated the impact of lifestyle improvement on CVD incidence using data from the China-PAR project (Prediction for Atherosclerotic Cardiovascular Disease Risk in China).@*METHODS@#A total of 12,588 participants free of CVD were followed up for three visits after the baseline examination. Changes in four lifestyle factors (LFs) (smoking, diet, physical activity, and alcohol consumption) were assessed through questionnaires from the baseline to the first follow-up visit. Cox proportional hazard models were used to estimate hazard ratios (HRs) and corresponding 95% confidence intervals (CIs). The risk advancement periods (RAPs: the age difference between exposed and unexposed participants reaching the same incident CVD risk) and population-attributable risk percentage (PAR%) were also calculated.@*RESULTS@#A total of 909 incident CVD cases occurred over a median follow-up of 11.14 years. Compared with maintaining 0-1 healthy LFs, maintaining 3-4 healthy LFs was associated with a 40% risk reduction of incident CVD (HR = 0.60, 95% CI: 0.45-0.79) and delayed CVD risk by 6.31 years (RAP: -6.31 [-9.92, -2.70] years). The PAR% of maintaining 3-4 unhealthy LFs was 22.0% compared to maintaining 0-1 unhealthy LFs. Besides, compared with maintaining two healthy LFs, improving healthy LFs from 2 to 3-4 was associated with a 23% lower risk of CVD (HR = 0.77, 95% CI: 0.60-0.98).@*CONCLUSIONS@#Long-term sustenance of healthy lifestyles or improving unhealthy lifestyles can reduce and delay CVD risk.

RESUMO

OBJECTIVE@#To study the cerebrospinal fluid (CSF) status and prognosis value in patients with newly diagnosed acute lymphoblastic leukemia (ALL) by flow cytometry (FCM).@*METHODS@#The clinical features of the 75 newly diagnosed ALL patients from September 2020 to December 2021 in our centre were retrospective analyzed, as well as the bone marrow (BM) and CSF minimal residual disease (MRD) data, and the CSF conventional cytology data. Central nervous system infiltration(CNSI) positive was as CSF MRD positive by FCM or leukemia cells detected by conventional cytology. The status of CSF were compared and analyzed by FCM and conventional cytology, the clinical features and the prognosis value of different CNSI status in these patients were analyzed.@*RESULTS@#Among 75 newly diagnosed ALL, 16 cases (21%) with CNSI positive (CNSI+) were detected by FCM, while only 2 positive cases (3%) were detected by conventional cytology. The CNSI+ rate detected by FCM was significantly higher than conventional cytology(P<0.05). Compared with CNSI- ALL patients, the median age of CNSI+ ALL patients was significantly younger, and the median platelet count was significantly lower, the difference was statistically significant (P<0.05). Up to follow-up time (August 31, 2022), four ALL patients were died, including 3 patients were CNSI- and 1 patient was CNSI+. Furthermore, three cases were primary disease relapse, including 1 case was CNSI+. There was no significant difference in overall survival (OS) rate and relapse-free survival (RFS) rate of the patients with different CNSI status.@*CONCLUSION@#Compared with conventional cytology, FCM is a more sensitive assay to evaluate the central nervous system status in ALL patients. After active treatment, there was no significant difference in OS and RFS between patients with different CNSI status at diagnosis.

RESUMO

Bone marrow microenvironment is a highly complex environment surrounding tumor, which plays an important role in the survival, proliferation, drug resistance and migration of multiple myeloma (MM) cells. As an important cellular component in tumor microenvironment, tumor-associated macrophages(TAM) has attracted attention due to its key role in tumor progression and drug resistance. Targeting TAM has shown potential therapeutic value in cancer treatment. In order to clarify the role of macrophages in MM progression, it is necessary to understand the differentiation of TAM and its characteristics of promoting MM. This paper reviews the research progress on how TAM is programmed in MM and the mechanism of TAM promoting tumor development and drug resistance.

RESUMO

OBJECTIVE@#To investigate the mutational spectrum in young patients with diffuse large B-cell lymphoma (DLBCL) based on next generation sequencing (NGS), and to provide a basis for in-depth understanding of the molecular biological characteristics and accurate prognosis of young DLBCL.@*METHODS@#From March 2009 to March 2021, 68 young DLBCL patients with complete initial diagnosis data from the Department of Hematology, The People's Hospital Xinjiang Uygur Autonomous Region were retrospectively analyzed, and their paraffin-embedded tissues were subjected to targeted sequencing analysis by NGS technology (including 475 Target genes), and the differences in gene mutation profiles and signaling pathways between high-risk patients with aaIPI ≥2 and low-intermediate risk patients with aaIPI <2 were compared.@*RESULTS@#A total of 44 high-frequency mutation genes were detected in 68 young DLBCL patients. By comparing the high-frequency mutation genes in aaIPI high-risk group and low-intermediate risk group, it was found that CARD11 mutation in aaIPI high-risk group was significantly higher than that in low-intermediate risk group (P =0.002), while MGA mutation (P =0.037) only appeared in the aaIPI high-risk group, and SPEN mutation (P =0.004) only appeared in the aaIPI low-intermediate risk group. The high-frequency mutation genes and clinical indicators of the aaIPI high-risk group were included in the survival analysis, and the results showed that TP53 (P =0.009, P =0.027), POU2AF1 (P =0.003, P =0.006) and CCND3 (P =0.040, P =0.014) genes mutations were associated with worse PFS and OS, while B2M was associated with better PFS (P =0.014) and OS (P =0.013). Multivariate COX regression analysis showed that the TP53, POU2AF1 and CCND3 were independent risk factors for PFS(P =0.021,P =0.005,P =0.020) and OS(P =0.042,P =0.010,P =0.013).@*CONCLUSION@#The aaIPI staging combination with molecular biology markers is more conducive to accurately judging the prognosis of young DLBCL patients. TP53, POU2AF1 and CCND3 mutations predict worse survival in the patients with the aaIPI high-risk group.

RESUMO

Objective To investigate the occupational lead exposure and blood lead levels of workers in a lead-acid battery factory in Wuhan in 2020 and analyze the influencing factors of blood lead, and to provide reference for the blood lead intervention of the workers in the lead-acid battery factory. Methods The blood lead test results of 320 occupational lead-exposed workers in the factory were investigated and the influencing factors were analyzed. Results Among the 320 blood lead samples collected, 4 people had blood lead≥400 μg/L, accounting for 1.25%, and 89 people had blood lead≥200 μg/L, accounting for 27.81%. Among them, there were 235 males with a median blood lead of 155.10 μg/L, and 85 females with a median blood lead of 82.40 μg/L. The Wilcoxon rank sum test results of two independent samples showed that the overall blood lead level of male employees was higher than that of female employees, and the difference was statistically significant (P 50 years old. Using the Bonferroni method to adjust the significance level for pairwise comparison, it was found that there were significant differences in the blood lead concentrations between the group under 40 years old, the group of 40 - 50 years old, and the group of over 50 years old ( P < 0.016 after adjustment). The employees were classified into different workshops, including 38 samples from the administrative workshop , 40 samples from the charging workshop, and 242 samples from the assembly workshop. Using the Bonferroni method to adjust the significance level for pairwise comparison, it was found that the blood lead concentrations in the administrative workshop, the charging workshop, and the assembly workshop were statistically different ( P <0.016 after adjustment). Conclusion The age, gender, and type of work of the employees in the battery factory all have a certain impact on the blood lead level. It is necessary to continuously improve the management of the labor hygiene operation system and strengthen the self-protection level of the workers, and regularly carry out occupational hygiene inspection and health monitoring.

RESUMO

Kidney is a highly vascularized organ and peritubular capillary network constitutes the critical component of its microvascular system. Peritubular capillaries, as the main vessels for blood supply in renal tubules and renal interstitium, involve in important physiological processes in renal tubules such as energy metabolism, substance secretion and reabsorption. In recent years, it has been demonstrated that ischemia-reperfusion injury, rejection and renal fibrosis during kidney transplantation would result in compromised structural integrity and decreased number in peritubular capillaries, thus leading to interstitial fibrosis in renal allograft, which would seriously affect the long-term stability of renal function in the renal allograft. Therefore, we reviewed the structure and function of peritubular capillary, peritubular capillary and ischemia-reperfusion injury, rejection and renal allograft fibrosis, focusing on the mechanism for peritubular capillary injury in kidney transplantation and the specific changes manifested, with the aim of providing a reference for preventing and treating perioperative complications in kidney transplantation and improving the long-term prognosis of grafts.

RESUMO

OBJECTIVE To build a standardized simulation teaching system for resident pharmacists and evaluate its effects, and to provide reference for improving the competency of resident pharmacists. METHODS The established simulation teaching system for pharmacy residents’ standardized training in the study included revising the simulation teaching syllabus, setting up simulation teaching courses, implementing the teaching method through “six types of simulations”, applying objective structured clinical examination (OSCE) for assessment, building a simulation teaching team and strengthening the simulation teaching management. The effect evaluation was perfermed with mixed research method, and qualitative and quantitative research methods were used to collect and analyze data and information. RESULTS &&CONCLUSIONS Compared with the traditional teaching system, the passing rate of graduation examination (71.4% vs. 100%) and the score of after-department examination ([ 76.2±7.8) vs. (90.4±4.9)] under the simulation teaching mode were higher; through questionnaire surveys and qualitative interviews, we found that resident pharmacists who went through simulation teaching gave positive feedback on the role and impact of this system. The simulation teaching system can be used with good generalizability for the standardized training of resident pharmacists, and can provide strong basis and support for the high-quality development of hospital pharmacy.

RESUMO

AIM:To systematically evaluate the efficacy and safety of intravitreal ranibizumab combined with compound trabeculectomy and panretinal photocoagulation(PRP)compared with compound trabeculectomy combined with PRP in the treatment of neovascular glaucoma(NVG).METHODS: Databases including Wanfang database, China National Knowledge Infrastructure(CNKI), PubMed, EMbase, China Biomedical Document Service System(CBM), Clinicalkey, and Cochrane Library were retrieved. Literatures about intravitreal ranibizumab combined with compound trabeculectomy and PRP in the treatment of NVG in the experimental group and compound trabeculectomy and PRP in the treatment of NVG in the control group from creation of database to July 20, 2022 were searched. At the same time, relevant reference were consulted. The best corrected visual acuity, intraocular pressure, occurrence of complications and the success rate of the surgery were systematically evaluated.RESULTS: A total of 8 clinical studies were included, with 864 patients(864 eyes)with NVG. Meta-analysis showed that the intraocular pressure of patients in the experimental group was lower than that in the control group at 1wk, 1 and 3mo after surgery(1wk: MD=-4.00, 95%CI: -4.62~-3.38, P&#x0026;#x003C;0.05; 1mo: MD=-4.11, 95%CI: -4.66~-3.56, P&#x0026;#x003C;0.05; 3mo: MD=-4.58, 95%CI: -5.61~-3.55, P&#x0026;#x003C;0.05). The best corrected visual acuity of the experimental group was better than that of the control group at 1mo after surgery(MD=0.17, 95%CI: 0.11~0.23, P&#x0026;#x003C;0.05), but there was no significant difference at 1wk after surgery(MD=0.08, 95%CI: -0.13~0.29, P=0.47). The patients in the experimental group had fewer complications(OR=0.30, 95%CI: 0.18~0.52, P&#x0026;#x003C;0.05)and higher surgical success rate(OR=5.15, 95%CI: 2.78~9.53, P&#x0026;#x003C;0.05).CONCLUSION:With decreased intraocular pressure, improved visual acuity and surgical success rate, intravitreal ranibizumab combined with compound trabeculectomy and PRP was better than the compound trabeculectomy and PRP in the treatment of NVG.

RESUMO

OBJECTVE To study the improvement effects of obacunone on renal interstitial fibrosis (RIF) in unilateral ureteral obstruction (UUO) model mice, and to investigate its mechanism based on ferroptosis mediated by nuclear factor erythroid 2- related factor 2(Nrf2)/glutathione peroxidase 4 (GPx4) signaling pathway. METHODS Thirty mice were randomly divided into sham operation group, model group, irbesartan group (positive control, 20 mg/kg), obacunone low-dose and high-dose groups (10, 40 mg/kg), with 6 mice in each group. Except for sham operation group, UUO model was established by ligation of unilateral ureter in other groups. After operation, administration groups were given intraperitoneal injection of relevant medicine, and sham operation group and model group were given intraperitoneal injection of constant volume of normal saline, once a day, for 7 consecutive days. The levels of creatinine (Cr) and blood urea nitrogen (BUN), the content of malondialdehyde (MDA) and the activities of total superoxide dismutase (T-SOD) in serum and the concentration of Fe2+ in renal tissue were all detected. HE staining and Masson staining were performed to observe the morphology and the fibrosis of renal tissues. Immunohisto- chemical staining was used to determine expressions of the fibronectin (Fn), α-smooth muscle actin (α-SMA), GPx4 964083717@qq.com and Nrf2 in renal tissue. Western blot and real-time quantitative polymerase chain reaction (RT-qPCR) were used E-mail:834300205@qq.com to detect the protein and mRNA levels of Fn, α-SMA, Nrf2, GPx4 and SLC7A11 in the renal tissues. RESULTS Compared with sham operation group, serum levels of Cr and BUN, the concentration of Fe2+ in renal tissue, the protein and mRNA levels of Fn and α-SMA in model group were increased significantly (P<0.05), while the activity of T-SOD in serum, protein and mRNA expressions of Nrf2, GPx4, SLC7A11 in kidney tissue were significantly decreased (P<0.05); in the kidney tissue, the renal tubules were dilated, the collagen deposition was obvious, the fibrous bands were thicker and darker, and the renal interstitial inflammatory cells infiltrated significantly. After intervened with obacunone, the levels of above indexes (except for mRNA expression of SLC7A11 in obacunone low-dose group) in serum and renal tissue were reversed significantly (P<0.05), and pathological damage and collagen deposition of kidney tissue were alleviated. CONCLUSIONS Obacunone can improve renal interstitial fibrosis of UUO model mice, the mechanism of which may be associated with activating the Nrf2/GPx4 pathway and then inhibiting ferroptosis to relieve RIF in UUO model mice.

RESUMO

Objective@#To understand the coincidence rate of adjustable and non adjustable desks and chairs in primary and secondary schools in Shanghai, so as to provide a reference for the effective management of desks and chairs in schools.@*Methods@#Stratified random cluster sampling was applied to measure 1 091 sets of desks and chairs in 33 classrooms of 7 primary and secondary schools in 4 districts of Shanghai including Huangpu, Hongkou, Yangpu and Jiading districts. The height examination data of seated students in the same semester were also collected to evaluate the matching type of functional size of desks and chairs and students height according to Functional Sizes and Technical Requirements of Chairs and Tables for Educational Institutions.@*Results@#The matching coincidence rate of desk and chair distribution in primary and secondary schools was 22.5%, and the matching coincidence rates of primary, middle and high schools were 11.7%, 27.1% and 40.9% respectively ( χ 2=83.23, P <0.01); the matching coincidence rate of adjustable desks and chairs (28.2%) was significantly higher than that of fixed (18.2%) ( χ 2=14.49, P <0.01). The type of distribution of desks and chairs that do not correspond to national standards, from elementary school to high school, showing a trend of high desks with high chairs, low desks with high chairs to high desks with low chairs.@*Conclusion@#The coincidence rate of desk and chair distribution in primary and secondary schools is low, and the adjustable desks and chairs has improved the problems to a certain extent, but has not significantly improved the coincidence rate. It is necessary to further explore the effective management mode in the use of adjustable desks and chairs and improve the current situation of the use of desks and chairs in schools.
