Fibrocartilaginous mesenchymoma: a clinicopathological analysis of four cases / 中华病理学杂志

Objective: To investigate the clinical, radiological, histological and molecular features and the differential diagnosis of fibrocartilaginous mesenchymoma (FM). Methods: Four cases of FM diagnosed in the Department of Pathology, the Sixth People's Hospital Affiliated to Shanghai Jiaotong University School of Medicine from 2020 to 2022 were analyzed. Related literature was also reviewed. Results: Case 1 was a 10-year-old girl with bone destruction in the sacrum and L5 articular processes revealed by CT scan. Case 2 was a 7-year-old girl with an aggressive lesion in her right distal ulna. Case 3 was an 11-year-old boy with a lesion in the metaphysis of his left proximal tibia. Case 4 was an 11-year-old boy with bone destruction in the distal portion of a radius. Microscopically, the four tumors all consisted of numerous spindle cells, hyaline cartilage nodules, and bone trabeculae. The hypocellular to moderately cellular spindle cell component contained elongated cells with slightly hyperchromatic, mildly atypical nuclei arranged in bundles or intersecting fascicles. Benign-appearing cartilaginous nodules of various sizes and shapes were scattered throughout the tumors. There were areas mimicking epiphyseal growth-plate characterized by chondrocytes arranged in parallel columns and areas of enchondral ossification. The stroma was rich in mucus in case 1. Mutation of GNAS and IDH1/IDH2 and amplification of MDM2 gene were not found in any of the three tested cases. Conclusions: FM is very rare and tends to affect young patients. It most frequently occurs in the metaphysis of long tubular bones, followed by the iliac-pubic bones and vertebrae. FM is characterized by a mixed population of spindle cells, hyaline cartilage nodules and trabeculae of bone, without specific immunophenotypes and molecular alternations. As a borderline, locally aggressive neoplasm, surgical removal with a wide margin is generally the treatment of choice for FM.

Cloning,subcellular localization and expression pattern analysis of transcription factor SmGRAS3 from Salvia miltiorrhiza / 中国中药杂志

GRAS transcription factors play important roles in the regulation of plant root growth and GA signaling. In this study,SmGRAS3 gene was cloned,which open reading frame was 2 247 bp,and encoding 748 amino acids. The physicochemical properties and structure of SmGRAS3 and its encoded protein were analyzed by bioinformatics software. This gene belongs to the SCL9 subfamily of the GRAS family,and its promoter sequence mainly contains the light response,stress response,and hormone response elements. It may interact with the GA signal pathway and anti-stress related proteins. The subcellular localization showed that SmGRAS3 protein was mainly located in the nucleus. The expression pattern analysis showed that the expression of Sm GRAS3 was the highest in the root and the lowest in the stem,and both light and low temperature could induce the high expression level of SmGRAS3. This study provides a foundation for further study on the roles of SmGRAS3 gene in the root growth and stress tolerance of Salvia miltiorrhiza.

Transcriptional activity and subcellular location of SmWRKY42-like and its response to gibberellin and ethylene treatments in Salvia miltiorrhiza hairy roots / 中草药·英文版

Objective: The exogenous gibberellin (GA) and ethylene (ET) treatment can improve the medicinal ingredients of Salvia miltiorrhiza. Interestingly, many reports pointed out that WRKY transcription factors played an important regulatory role in these treatment responses. However, whether the SmWRKY mediate these treatment signalings in S. miltiorrhiza remains largely elusive. Methods: qRT-PCR was used for SmWRKY42-like in response to exogenous GA and ethephon (Eth) treatment. The subcellular location of SmWRKY42-like was transiently transformed into onion epidermal cells by particle bombardment. The self-activating activity of SmWRKY42-like was verified in AH109 yeast strain. Results: SmWRKY42-like was a WRKY family gene in S. miltiorrhiza. The subcellular localization and transcriptional activity results of the SmWRKY42-like protein indicated that SmWRKY42-like mainly enriched in nucleus and might be a transcription factor in S. miltiorrhiza. In the meantime, the SmWRKY42-like gene significantly responded to exogenous GA and Eth treatment. Conclusion: These results collectively indicated the SmWRKY42-like gene functions, as an important hormone-responsive gene, might play a potentially role in ET and GA signaling pathways.

Impact of Extended Ambulatory Electrocardiogram Monitoring on Detection Rate of Arrhythmia in Chronic Heart Failure Patients / 中国循环杂志

Objective: To compare the detection rate of arrhythmia in chronic heart failure (CHF) patients by different time of ambulatory electrocardiogram (Holter). Methods: A total of 108 consecutive elderly CHF patients received 72h Holter in our hospital from 2016-01 to 2016-09 were enrolled. According to NYHA classification, LVEF and plasma NT-proBNP level, the patients were divided into 3 sets of groups. Detection rates of supra-ventricular arrhythmia and ventricular arrhythmia were compared among 24h, 48h and 72h Holter recording. Results: Based on NYHA classification, the patients were divided into 3 groups: NYHA Ⅱ group, n=24, NYHAⅢ group, n=42 and NYHAⅣ group, n=26; based on NT-proBNP level, the patients were divided into 2 groups: NT-proBNP≥1000 pg/ml group and NT-proBNP<1000 pg/ml group, n=54 in each group; based on LVEF, the patients were divided into 3 groups: HFpEF group, n=80, HFmrEF group, n=13 and HFrEF group, n=15. Detection rate for non-sustained atrial tachycardia (NSAT) was 81.7% by 48h Holter which was higher than 64.6% at 24h, P<0.01; for non-sustained ventricular tachycardia (NSVT) was 38% at 72h which was higher than 25.9% at 24h, P<0.01. For new-onset paroxysmal atrial fibrillation, only 1 patient was detected by 24h Holter and the additional 3 patients were detected by 72h. Group analysis indicated that the detection rate of NSVT was different by 72h and 24h Holter in NYHA Ⅲ patients, P<0.05; while it was similar in NYHA Ⅳ patients, P>0.05. Conclusion: Long term (72h/48h) Holter had the higher detection rate of arrhythmia in HF patients, 24 h monitoring was easier to find NSVT in severer HF patients. In moderate to severe HF patients, the detection time may be prolonged if NSVT couldn't be found by 24h Holter which was helpful for clinical treatment.

<p><b>OBJECTIVE</b>To detect K-ras gene mutations in plasma free DNA by peptide nucleic acid clamp PCR assay (PNA-PCR) and nested primer PCR, and to analyze the correlation between K-ras mutations and prognosis in patients with metastatic colorectal cancer (mCRC).</p><p><b>METHODS</b>Peripheral blood was collected and free DNA was extracted from plasma in 106 patients with mCRC. Nested primer PCR and PNA-PCR were used to detect K-ras gene mutation in the plasma free DNA. The patients were divided into three groups by K-ras status: wild-type group (wild-type determined by both methods), low mutation group (mutation by PNA-PCR method, wild-type by nested primer PCR method) and high mutation group (mutation by two methods). The correlation between K-ras mutations and prognosis was analyzed.</p><p><b>RESULTS</b>The mutation rate of K-ras in tumor tissues of the 106 patients was 40.6%. The Mutation rate of K-ras in plasma free DNA detected by PNA-PCR was 31.1%, significantly higher than that of 15.1% detected by nested primer PCR (P = 0.006). The consistent rate of the K-ras status in plasma free DNA detected by PNA-PCR and that in tumor tissue detected by traditional method was up to 83.0%. The median overall survival (OS) of patients of the wild type, low mutation and high mutation groups was 23.5 months, 17.3 months and 13.9 months, respectively (P = 0.002). The median progression-free survival (PFS) of the K-ras wild-type, low mutation and high mutation groups with first-line chemotherapy was 6.8 months, 6.1 months and 3.2 months, respectively (P = 0.002), and the median OS of them were 23.0 months, 15.5 months and 13.9 months, respectively (P = 0.036). The overall response rate (ORR) was improved in the K-ras wide-type patients who received cetuximab combined with chemotherapy as first-line therapy (75.0% vs. 23.4%, P = 0.058). Cetuximab combined with in second-line therapy chemotherapy led to a significant improvement in disease control rate (DCR) ( 100% vs. 35.7%, P < 0.001) as compared with those of chemotherapy alone. COX regression model showed that K-ras status detected by PNA-PCR, ECOG PS, number of surgery and initially metastatic site were independent factors for prognosis.</p><p><b>CONCLUSIONS</b>PNA-PCR for the detection of K-ras mutation in plasma free DNA can be used to substitute the traditional method for detection of K-ras mutation in tumor tissues.
