RESUMO

ObjectiveThis study aims to explore the effect of ultrasound-guided superficial parasternal intercostal plane block on the quality of recovery and postoperative analgesia in patients undergoing sternotomy cardiac surgery. MethodsA total of 64 patients undergoing sternotomy cardiac surgery were selected for this study. They were randomly divided into two groups: one group received a superficial parasternal intercostal plane block with ropivacaine (the ropivacaine group), while the other was given normal saline (the normal saline group). The primary outcome was the Quality of Recovery-15 (QoR-15) score on postoperative day 1 in both groups, accompanied by a comparative analysis of the pain score and opioid usage. ResultsCompared with the normal saline group, the ropivacaine group exhibited a significantly higher QoR-15 score on postoperative day 1[(89.60±13.24) vs (81.18±12.78), P=0.012]. The numerical rating scale at rest was significantly lower[(3.03±0.72) vs (4.26±0.93), P<0.001], and the numerical rating scale during coughing was also significantly reduced [(4.40±0.89) vs (5.44±1.05), P<0.001]. Concurrently, the cumulative morphine equivalent consumption during the initial 24 h postoperatively was significantly lower in patients who were administered the ropivacaine [14.15 (4.95~30.00) mg vs 40.50 (19.25~68.18) mg, P=0.002], and there was also a notable decrease in the rescue analgesia [0.00 (0.00~0.00) mg vs 0.00 (0.00~100.00) mg, P=0.007]. ConclusionUltrasound-guided superficial parasternal intercostal plane block can significantly enhance the overall quality of recovery in patients undergoing sternotomy cardiac surgery on postoperative day 1. The technique contributes to improved postoperative analgesic effects and a reduction in opioid usage, thereby facilitating early postoperative recovery.

RESUMO

Objective: To investigate the characteristics of gene mutations in angioimmunoblastic T-cell lymphoma (AITL). Methods: Seventy-five AITL cases diagnosed at the Department of Pathology, Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine, Shanghai, China from June 2021 to June 2023 were included. Their formalin-fixed and paraffin-embedded or fresh tissues were subject to targeted next generation sequencing (NGS). The sequencing data was collected, and the distribution and type of gene mutations were analyzed. Results: 492 potential driver mutations were identified in 74 out of the 84 genes. Targeted sequencing data for the 75 AITL patients showed that the genes with mutation frequencies of ≥10% were TET2 (89.3%), RHOA (57.3%), IDH2 (37.3%), DNMT3A (36.0%), KMT2C (21.3%), PLCG1 (12.0%), and KDM6B (10.7%). There were significant co-occurrence relationships between TET2 and RHOA, TET2 and IDH2, and RHOA and IDH2 gene mutations (P<0.05), respectively, while TET2 and KDM6B gene mutations were mutually exclusive (P<0.05). Conclusions: The study reveals the mutational characteristics of AITL patients using NGS technology, which would provide insights for molecular diagnosis and targeted therapy of AITL.

RESUMO

BACKGROUND@#With an increasing proportion of multiparas, proper interpregnancy intervals (IPIs) are urgently needed. However, the association between IPIs and adverse perinatal outcomes has always been debated. This study aimed to explore the association between IPIs and adverse outcomes in different fertility policy periods and for different previous gestational ages.@*METHODS@#We used individual data from China's National Maternal Near Miss Surveillance System between 2014 and 2019. Multivariable Poisson models with restricted cubic splines were used. Each adverse outcome was analyzed separately in the overall model and stratified models. The stratified models included different categories of fertility policy periods (2014-2015, 2016-2017, and 2018-2019) and infant gestational age in previous pregnancy (<28 weeks, 28-36 weeks, and ≥37 weeks).@*RESULTS@#There were 781,731 pregnancies enrolled in this study. A short IPI (≤6 months) was associated with an increased risk of preterm birth (OR [95% CI]: 1.63 [1.55, 1.71] for vaginal delivery [VD] and 1.10 [1.03, 1.19] for cesarean section [CS]), low Apgar scores and small for gestational age (SGA), and a decreased risk of diabetes mellitus in pregnancy, preeclampsia or eclampsia, and gestational hypertension. A long IPI (≥60 months) was associated with an increased risk of preterm birth (OR [95% CI]: 1.18 [1.11, 1.26] for VD and 1.39 [1.32, 1.47] for CS), placenta previa, postpartum hemorrhage, diabetes mellitus in pregnancy, preeclampsia or eclampsia, and gestational hypertension. Fertility policy changes had little effect on the association of IPIs and adverse maternal and neonatal outcomes. The estimated risk of preterm birth, low Apgar scores, SGA, diabetes mellitus in pregnancy, and gestational hypertension was more profound among women with previous term births than among those with preterm births or pregnancy loss.@*CONCLUSION@#For pregnant women with shorter or longer IPIs, more targeted health care measures during pregnancy should be formulated according to infant gestational age in previous pregnancy.

RESUMO

Autoimmune hepatitis (AIH) is an autoimmune disease characterized by chronic liver inflammation, with a gradually increasing incidence rate, and its social and medical burdens cannot be neglected. Intestinal microecology is becoming a research hotspot in the field of autoimmune disease. In recent years, it has been believed that changes in intestinal microecology can cause changes in autoimmune state, microbial metabolites, and intestinal barrier, which is one of the driving factors for the onset of AIH. Early diagnosis and correct treatment can help to improve the prognosis of AIH patients. This article introduces the characteristics of gut microbiota in AIH patients, elaborates on the impact of intestinal microflora imbalance on the pathogenesis of AIH, and briefly describes related treatment regimens from the perspective of intestinal microecology, so as to comprehensively understand and explain the role of intestinal microecology in AIH and the impact of intestinal microecology balance on the pathogenesis, diagnosis, and treatment of AIH.

RESUMO

@#Objective     To investigate the effects of different types of tricuspid regurgitation, implantation positions, and device models on the treatment outcomes of K-Clip for tricuspid regurgitation using numerical simulations. Methods     Three-dimensional reconstruction of the heart model was performed based on CT images. Two different regurgitation orifices were obtained by modifying the standard parameterized tricuspid valve leaflets and chordae tendineae. The effects of different K-Clip models at different implantation positions (posterior leaflet midpoint, anterior-posterior commissure, anterior leaflet midpoint, posterior septal commissure) were simulated using commercial explicit dynamics software Ls-Dyna. Conclusion     For the two types of regurgitation in this study, clipping at the posterior leaflet midpoint resulted in a better reduction of the regurgitation orifice (up to 75% reduction in area). Higher clamping forces were required for implantation at the anterior leaflet midpoint and posterior septal commissure, which was unfavorable for the smooth closure of the clipping components. There was no statistical difference in the treatment outcomes between the 18T and 16T K-Clip components, and the 16T component required less clamping force. Therefore, the use of the 16T K-Clip component is recommended.

RESUMO

ObjectiveTo investigate the effects of Jiaohong pills (JHP) and its prescription, Pericarpium Zanthoxyli (PZ) and Rehmanniae Radix (RR) cognitive dysfunction in scopolamine-induced Alzheimer's disease (AD) mice and its mechanism through pharmacodynamic and metabolomics study. MethodThe animal model of AD induced by scopolamine was established and treated with PZ, RG and JHP, respectively. The effects of JHP and its formulations were investigated by open field test, water maze test, object recognition test, avoidance test, cholinergic system and oxidative stress related biochemical test. Untargeted metabolomics analysis of cerebral cortex was performed by ultra-performance liquid chromatography-Quadrupole/Orbitrap high resolution mass spectrometry (UPLC Q-Exactive Orbitrap MS). ResultThe behavioral data showed that, compared with the model group, the discrimination indexes of the high dose of JHP, PZ and RR groups was significantly increased (P<0.05). The staging rate of Morris water maze test in the PZ, RR, high and low dose groups of JHP was significantly increased (P<0.05, P<0.01), the crossing numbers in the PZ, JHP high and low dose groups were significantly increased (P<0.05, P<0.01); the number of errors in the avoidance test were significantly reduced in the PZ and high-dose JHP groups (P<0.01), and the error latencies were significantly increased in the JHP and its prescription drug groups (P<0.01). Compared with the model group, the activities of acetylcholinesterase in the cerebral cortex of the two doses of JHP group and the PZ group were significantly increased (P<0.05, P<0.01), and the activity of acetylcholinesterase in the high-dose JHP group was significantly decreased (P<0.05), and the level of acetylcholine was significantly increased (P<0.01). At the same time, the contents of malondialdehyde in the serum of the two dose groups of JHP decreased significantly (P<0.05, P<0.01). The results of metabolomics study of cerebral cortex showed that 149 differential metabolites were identified between the JHP group and the model group, which were involved in neurotransmitter metabolism, energy metabolism, oxidative stress and amino acid metabolism. ConclusionJHP and its prescription can antagonize scopolamine-induced cognitive dysfunction, regulate cholinergic system, and reduce oxidative stress damage. The mechanism of its therapeutic effect on AD is related to the regulation of neurotransmitter, energy, amino acid metabolism, and improvement of oxidative stress.

RESUMO

Demyelination of the central nervous system often occurs in neurodegenerative diseases, such as multiple sclerosis (MS). The myelin sheath, a layer of myelin membrane wrapping the axon, plays a role in the rapid conduction and metabolic coupling of impulses for neurons. The exposure of the axon will lead to axonal degeneratio, and further neuronal degeneration, which is the main cause of dysfunction and even disability in patients with demyelinating neurodegenerative diseases. In addition to the demyelination of mature myelin sheath, remyelination disorder is also one of the major reasons leading to the development of the diseases. The myelin sheath is composed of oligodendrocytes (OLs) derived from oligodendrocyte progenitor cells (OPCs) which are differentiated from neural stem cells (NSCs). The process of myelin regeneration, i.e., remyelination, is the differentiation of NSCs into OLs. Recent studies have shown that this process is regulated by a variety of genes. MicroRNAs, as important regulators of neurodegenerative diseases, form a complex regulatory network in the process of myelin regeneration. This review summarizes the main molecular pathways of myelin regeneration and microRNAs involved in this process and classifies the mechanisms and targets. This review is expected to provide a theoretical reference for the future research on the treatment of demyelinating diseases by targeting the regulation of microRNAs.

RESUMO

This study used the zebrafish model to explore the hepatotoxicity of Rhododendri Mollis Flos(RMF). The mortality was calculated according to the number of the survival of zebrafish larvae 4 days after fertilization under different concentration of RMF, and the dose-toxicity curve was fitted to preliminarily evaluate the toxicity of RMF. The liver phenotypes under the sublethal concentration of RMF in the treatment group and the blank control group were observed by hematoxylin-eosin(HE) staining and acridine orange(AO) staining. Meanwhile, the activities of alanine aminotransferase(ALT) and aspartate aminotransferase(AST) were determined to confirm the hepatotoxicity of RMF. Real-time quantitative polymerase chain reaction(real-time PCR) and Western blot were used to determine the expressions of genes and proteins in zebrafish larvae. Gas chromatography time-of-flight mass spectrometry(GC-TOF-MS) was used to conduct untargeted metabolomics testing to explore the mechanism. The results showed that the toxicity of RMF to zebrafish larvae was dose-dependent, with 1 100 μg·mL~(-1) of the absolute lethal concentration and 448 μg·mL~(-1) of sublethal concentration. The hepatocyte apoptosis and degeneration appeared in the zebrafish larvae under the sublethal concentration of RMF. The content of ALT and AST in zebrafish larvae at the end of the experiment was significantly increased in a dose-dependent manner. Under the sublethal concentration, the expressions of genes and proteins related to apoptosis in zebrafish larvae were significantly increased as compared with the blank control group. The results of untargeted metabolomics showed that the important metabolites related to the he-patotoxicity of RMF were mainly enriched in alanine, aspartic acid, glutamic acid, and other pathways. In conclusion, it is inferred that RMF has certain hepatotoxicity to zebrafish larvae, and its mechanism may be related to apoptosis.

RESUMO

Multiple sclerosis(MS) shows the pathological characteristics of "inflammatory injury of white matter" and "myelin repair disability" in the central nervous system(CNS). It is very essential for MS treatment and reduction of disease burden to strengthen repair, improve function, and reduce disability. Accordingly, different from the simple immunosuppression, we believe that key to strengthening remyelination and maintaining the "damage-repair" homeostasis of tissue is to change the current one-way immunosuppression strategy and achieve the "moderate pro-inflammation-effective inflammation removal" homeostasis. Traditional Chinese medicine shows huge potential in this strategy. Through literature research, this study summarized the research on remyelination, discussed the "mode-rate pro-inflammation-effective inflammation removal" homeostasis and the "damage-repair" homeostasis based on microglia, and summed up the key links in remyelination in MS. This review is expected to lay a theoretical basis for improving the function of MS patients and guide the application of traditional Chinese medicine.

RESUMO

In this study, an ultra-performance liquid chromatography-quadrupole time-of-flight high resolution mass spectrometer(UPLC-Q-TOF-HRMS) was used to investigate the effects of the active ingredients in Periploca forrestii compound on spleen metabolism in rats with collagen-induced arthritis(CIA), and its potential anti-inflammatory mechanism was analyzed by network pharmacology. After the model of CIA was successfully established, the spleen tissues of rats were taken 28 days after administration. UPLC-Q-TOF-HRMS chromatograms were collected and analyzed by principal component analysis(PCA), orthogonal partial least squares discriminant analysis(OPLS-DA), and MetPA. The results showed that as compared with the blank control group, 22 biomarkers in the spleen tissues such as inosine, citicoline, hypoxanthine, and taurine in the model group increased, while 9 biomarkers such as CDP-ethanolamine and phosphorylcholine decreased. As compared with the model group, 21 biomarkers such as inosine, citicoline, CDP-ethanolamine, and phosphorylcholine were reregulated by the active ingredients in P. forrestii. Seventeen metabolic pathways were significantly enriched, including purine metabolism, taurine and hypotaurine metabolism, glycerophospholipid metabolism, and cysteine and methionine metabolism. Network pharmacology analysis found that purine metabolism, glycerophospholipid metabolism, and cysteine and methionine metabolism played important roles in the pathological process of rheumatoid arthritis. This study suggests that active ingredients in P. forrestii compound can delay the occurrence and development of inflammatory reaction by improving the spleen metabolic disorder of rats with CIA. The P. forrestii compound has multi-target and multi-pathway anti-inflammatory mechanism. This study is expected to provide a new explanation for the mechanism of active ingredients in P. forrestii compound against rheumatoid arthritis.

RESUMO

OBJECTIVES@#Intracerebral hemorrhage (ICH) has the highest mortality and disability rates among various subtypes of stroke. Previous studies have shown that the gut microbiome (GM) is closely related to the risk factors and pathological basis of ICH. This study aims to explore the causal effect of GM on ICH and the potential mechanisms.@*METHODS@#Genome wide association study (GWAS) data on GM and ICH were obtained from Microbiome Genome and International Stroke Genetics Consortium. Based on the GWAS data, we first performed Mendelian randomization (MR) analysis to evaluate the causal association between GM and ICH. Then, a conditional false discovery rate (cFDR) method was conducted to identify the pleiotropic variants.@*RESULTS@#MR analysis showed that Pasteurellales, Pasteurellaceae, and Haemophilus were negatively correlated with the risk of ICH, whileVerrucomicrobiae, Verrucomicrobiales, Verrucomicrobiaceae, Akkermansia, Holdemanella, and LachnospiraceaeUCG010 were positively correlated with ICH. By applying the cFDR method, 3 pleiotropic loci (rs331083, rs4315115, and rs12553325) were found to be associated with both GM and ICH.@*CONCLUSIONS@#There is a causal association and pleiotropic variants between GM and ICH.

RESUMO

At present, major depressive disorder (MDD) is highly prevalent with advanced neurological disorders as the main pathological manifestations. As the physiological function bearer of higher neural activity, gray matter has become the focus of MDD treatment. However, recent research has shown that white matter and gray matter are independent of each other in the central nervous system (CNS), and their functions are integrated and linked. In addition to gray matter damage, white matter damage is also the core driving event of disease progression and determines the outcome of MDD. At the treatment level, the current drug treatment of MDD mainly focuses on gray matter repair, while ignoring the importance of white matter integrity for the treatment of the disease, which has become the weakness of the current treatment of MDD. Traditional Chinese medicine (TCM) has good application potential in white matter repair. This paper elaborated on the following three aspects. ① The roles of white matter damage in the occurrence and development of MDD were summarized. ② The key link of white matter repair in MDD was elaborated with microglia microenvironment regulation as the entry point. ③ The application value of TCM in white matter repair in MDD was analyzed. This review aims to highlight the importance of white matter integrity in the treatment of MDD and is expected to expand the understanding dimension of the activity of related Chinese medicines in MDD from the perspective of white matter repair and analyze its potential application value.

RESUMO

To explore the suitable fertilizing pattern for Saposhnikovia divaricata in the genuine producing area, a field trial was carried out to investigate the changes in the yield and quality of medicinal materials and soil in different fertilization patterns, such as organic fertilizer substitution(organic fertilizer+NPK fertilizer) and chemical fertilizer reduction(organic fertilizer+NPK fertilizer decrement and organic fertilizer+NPK fertilizer decrement+soil conditioner). The comprehensive analysis of all treatments was based on the medicine quality evaluation data set and soil quality evaluation data set, respectively, by CRITIC weight method. The results showed that(1) the yield of S. divaricate increased by 4.93%-12.67% under the organic fertilizer substitution mode, and the yield increased by 44.43% under the treatment of chemical fertilizer reduction YHT15, which was higher than that of the organic fertilizer substitution mode.(2) The quality of S. divaricate under the two fertilization modes was superior to the standard in the Chinese Pharmacopoeia, and the application of biochar was helpful to improve the quality of S. divaricate quality, with an increase of 82.83%-181.54%. CRITIC method analysis showed that fertilization treatments with high comprehensive scores were YHT15, YH30, and YH15.(3) Soil quality under the two fertilization modes was higher than that under the control. The fertilization treatments with higher comprehensive scores of soil quality were YHT15, YHT30, and YHT. The fertilization mode of adding biochar as soil conditioner, applying an appropriate amount of organic fertilizer, and reducing part of chemical fertilizer is the appropriate way to develop ecological plantation of S. divaricata in the Baicheng area in the western Jilin province. The specific fertilization mode is as follows. The basic fertilizer was 361 kg·hm~(-2) superphosphate+110 kg·hm~(-2) potassium sulfate+82 kg·hm~(-2) organic fertilizer+10 000 kg·hm~(-2) rice husk biochar, and urea was applied as top fertilizer three times, 29, 29, and 20 kg·hm~(-2), respectively.

RESUMO

As the research of traditional Chinese medicine (TCM) on knee osteoarthritis (KOA) is progressing, researchers have discovered that a variety of Chinese medicines can delay the progress of KOA by regulating signaling pathways at the molecular level. The Chinese medicines and their active ingredients mentioned in this article are associated with the signaling pathways in KOA. They can regulate the levels of targeted molecules via different signaling pathways to inhibit cartilage inflammatory cytokine, apoptosis, and cartilage matrix degradation and promote chondrocyte autophagy, so as to reduce the synovial inflammatory edema and delay cartilage degeneration. This paper systematically reviews the studies about the TCM intervention of KOA. Baicalein can reduce the inflammatory cytokines and apoptosis and promote the autophagy of chondrocytes by blocking the phosphatidylinositol-3 kinase/protein kinase (PI3K/Akt) signaling pathway. Cornuside I can decrease the phosphorylation activity of Janus kinase 2/signal transducer and activator of transcription 3 (JAK2/STAT3) pathway to reduce synovial inflammation and delay cartilage matrix degeneration. Salvianolic acid A can reduce inflammation and cartilage matrix degradation by inhibiting the phosphorylation of the nuclear factor-κB (NF-κB) pathway. Emodin can reduce the activity of Wnt/β-catenin pathway to inhibit the decomposition of collagen and proteoglycan. Myristicoside can inhibit apoptosis by blocking the p38 mitogen-activated protein kinase (p38 MAPK) signaling pathway. Akebia saponin D can enhance the activity of nuclear factor E2-related factor 2/heme oxygenase 1(Nrf2/HO-1) pathway to inhibit oxidative stress in chondrocytes. The saponins in Achyranthis Bidentatae Radix reduce cartilage matrix degradation by enhancing the transforming growth factor-β (TGF-β)/Smad signaling pathway. Crocin inhibits the cartilage inflammation and apoptosis factor increase by stimulating the activity of hippo-Yes-associated protein (Hippo-YAP). Ligustrazine blocks the Notch pathway to improve the morphology and abnormality of chondrocytes. Oleanolic acid reduces the destruction and degeneration of cartilage matrix via the estrogen signaling pathway. The above summary aims to provide references for future clinical and experimental research on KOA.

RESUMO

Objective: To observe the clinical efficacy of herbal cake-partitioned moxibustion for ulcerative colitis (UC) and elucidate its mechanism by targeting the vitamin D receptor (VDR) signaling pathway. Methods: A total of 63 patients with UC were randomly divided into an observation group (30 cases, treated with herbal cake-partitioned moxibustion) and a control group (33 cases, treated with sham herbal cake-partitioned moxibustion). Moxibustion treatment was performed at Qihai (CV6) and bilateral Tianshu (ST25) and Shangjuxu (ST37), 3 times per week for 12 weeks. The total effective rate, visual analog scale (VAS) score for abdominal bloating and pain, and hospital anxiety and depression scale (HADS) score were compared between the two groups. Enzyme-linked immunosorbent assay was used to detect the concentrations of serum C-reactive protein (CRP), 25-hydroxyvitamin D [25(OH)D], and interleukin-12 (IL-12)/interleukin-23 (IL-23) p40. Immunohistochemistry was used to observe the expression levels of VDR and regenerating gene Ⅳ (Reg Ⅳ) proteins in colonic mucosa. The expression levels of VDR, cytochrome p45027B1 (CYP27B1), and Reg Ⅳ mRNAs were detected by real-time fluorescence quantitive polymerase chain reaction. Results: After treatment, the total effective rate in the observation group was 86.7%, which was significantly higher than 51.5% in the control group (P<0.05). After treatment, the VAS scores for abdominal bloating and pain in the observation group were significantly decreased (P<0.01), as well as the HADS-depression subscale (HADS-D) and HADS-anxiety subscale (HADS) scores (P<0.05), while only the VAS score for abdominal pain in the control group was reduced (P<0.05), and the improvements of the scores in the observation group were more significant than those in the control group (P<0.05). After treatment, the serum CRP concentrations in both groups and the IL-12/IL-23 p40 concentration in the observation group were significantly decreased (P<0.05), and the concentrations in the observation group were lower than those in the control group (P<0.05). The expression levels of VDR protein and mRNA in the colon in both groups were all increased (P<0.01), and the expression levels of Reg Ⅳ protein and mRNA and CYP27B1 mRNA were all decreased in the two groups (P<0.05 or P<0.01); the improvements in the observation group were more notable than those in the control group (P<0.05 or P<0.01). Conclusion: Herbal cake-partitioned moxibustion can effectively alleviate abdominal pain and diarrhea in patients with UC, improve depression and anxiety disorders, and regulate the expression of related proteins in the VDR signaling pathway. The mechanism may be related to inhibiting intestinal inflammation by reducing the release of the proinflammatory cytokine IL-12/IL-23 p40.

RESUMO

The standardized treatment of malignant tumor has always been the direction of continuous improvement of major medical institutions. In recent years, the basic research, prevention, screening and diagnosis and treatment level of gastric, gastroesophageal junction and esophageal cancer have been greatly improved, resulting in a significant improvement in the 5 years′ survival rate of patients, but there are still great differences in the diagnosis and treatment level among different regions. Chinese gastric cancer, gastroesophageal junction cancer and esophageal cancer differ greatly from European and American countries in etiology, pathological types, high incidence sites, etc. Therefore, the relevant guidelines of European and American countries cannot fully meet Chinese clinical practice. In 2021, Elsevier Publishing Group launched the Chinese edition of Elsevier clinical pathway for gastric, gastroesophageal junction and esophageal cancer, and the first update edition was made in 2022, which aims to promote the quality control of tumor diagnosis and treatment, standardize tumor diagnosis and treatment behaviors, promote the homogenization and standardization of tumor diagnosis and treatment, and ultimately improve the survival rate and quality of life of patients with malignant tumor. This pathway refers to the National Comprehensive Cancer Network clinical practice guidelines, the Chinese Society of Clinical Oncology guidelines, combines evidence-based medicine and clinical experience, and follows the scientific, universal, standardized and operable principles. It has been promoted and applied in clinical practice, and is constantly updated according to the latest research results.

RESUMO

In November 2019, we received and treated a patient with MTSCC of the left kidney. The tumor was located at the upper pole of the left kidney, with a size of 23.3 cm×18.0 cm×21.8 cm. She underwent transperitoneal radical nephrectomy. There was no local recurrence or distant metastasis during the follow-up of 3 years and 2 months. MTSCC of the kidney is a rare subtype of renal carcinoma, with slower disease progression, a clear and smooth rim, and fewer invasion or metastasis. Its final diagnosis should depend on pathology examination. Surgical treatment is the only effective intervention for this disease at present.

RESUMO

Objective:To investigate the clinical, pathological and CT characteristics of lung adenocarcinoma patients with epidermal growth factor receptor (EGFR) 19 and 21 exon mutations.Methods:Clinical, pathological and imaging data of 683 patients with lung adenocarcinoma in the First Affiliated Hospital of Chongqing Medical University from December 2012 to December 2020 were retrospectively analyzed. According to the gene mutation status, patients were divided into EGFR common loci mutation group (exons 19 or 21) with 382 cases (mutation group), including 19 exon mutation in 165 cases (exon 19 mutation subgroup) and 21 exon mutation in 217 cases (exon 21 mutation subgroup), and EGFR negative mutation group with 301 cases (negative mutation group). Independent sample t-test and χ 2 test were used to compare those features between mutation group and negative mutation group, exon 19 mutation subgroup and exon 21 mutation subgroup. The indicators with statistically significant differences in univariate analysis were included in binary logistic regression analysis to screen out independent predictors and establish the model. Receiver operating characteristic curve and area under curve (AUC) were used to evaluate the predictive performance of the model or index. Results:There were significant differences between mutation group and negative mutation group in gender distribution, smoking history, the proportion of solid-dominated growth pattern, peripheral distribution, tumor maximum diameter (3 cm as the cut-off point) distribution, spiculation, ground-glass opacity (GGO), air bronchogram, vascular convergence sign, pleural retraction, the number of lung metastases (10 as the cut-off point), pleural effusion, necrosis, and lymph node metastasis in lung adenocarcinoma patients ( P<0.05). The logistic regression showed that female (OR=5.230,95%CI 3.534-7.740, P<0.001), non-smoking history (OR=2.970, 95%CI 1.986-4.443, P<0.001), GGO (OR=3.092, 95%CI 1.746-5.477, P<0.001), absence of necrosis (OR=1.754, 95%CI 1.047-2.939, P=0.033), vascular convergence sign (OR=3.129, 95%CI 1.971-4.969, P<0.001), pleural retraction (OR=2.434, 95%CI 1.680-3.526, P<0.001), and the number of lung metastases≥10 (OR=2.242, 95%CI 1.284-3.915, P=0.005) were independent predictors of EGFR exon 19 and 21 mutations, and the AUC of the logistic model based on these predictors in predicting EGFR exon 21 and 19 mutations in lung adenocarcinoma was 0.804. There were significant differences between EGFR exon 19 mutation subgroup and EGFR 21 mutation subgroup in gender distribution, the proportion of acinar-dominated growth pattern, peripheral distribution, vascular convergence sign, pleural retraction ( P<0.05). The logistic regression showed that vascular convergence sign (OR=1.833, 95%CI 1.187-2.831, P=0.006) was independent predictor of EGFR exon 21, the AUC of vascular convergence sign for distinguishing EGFR exon 19 and EGFR 21 mutation was 0.604. Conclusions:There are some differences in the clinical, pathological, and CT features of patients between EGFR common loci mutation and EGFR negative mutations, EGFR exon 19 and exon 21 mutations in lung adenocarcinoma. Familiarity with these differences is helpful for the individualized treatment of patients with unknown gene mutation status of lung adenocarcinoma.

RESUMO

Osteochondral lesion of talus (OLT) is a foot and ankle disease characterized by ankle pain, which may impact the joint function and life quality. If managed improperly, it may lead to a further ankle arthritis, severely compromising the prognosis. The therapeutic effect of conservative treatment for OLT is still uncertain. Surgery is still the main treatment modality for OLT with various techniques. However, the optimized surgical technique is still inconclusive, furthermore, regeneration and repair of cartilage after debridement is also a great challenge for the treatment of OLT. Platelet-rich plasma (PRP) with good repair effect on cartilage injury is gradually applied in the treatment of OLT. However, there still lacks the unified understanding of the technique and specification of PRP for the treatment of OLT. Therefore, National Orthopedics Center of Shanghai Sixth People′s Hospital allied Foot Ankle Basic Research & Orthopedics Group, Chinese Association of Orthopedic Surgeons; Foot and Ankle Committee of Chinese Association of Sports Medicine Physicians; and Foot and Ankle Group of Orthopedic Specialized Branch of Shanghai Medical Association to organize related experts to formulate the Expert consensus on platelet- rich plasma treatment for osteochondral lesion of talus ( version2023). Fifteen recommendations were put forward upon PRP preparation, indications, contraindications and treatment methods of PRP for OLT, so as to standardize the PRP treatment for OLT.
