Mutation characteristics of angioimmunoblastic T-cell lymphoma: an analysis of 75 cases / 中华病理学杂志

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.

The effect of esketamine on postoperative recovery in children after endoscopic adenoidectomy / 复旦学报（医学版）

Objective To observe the effect of esketamine on postoperative recovery in children after endoscopic adenoidectomy.Methods Sixty pediatric patients who underwent adenoidectomy with endoscope from Jan 2022 to Jan 2023 in Eye&ENT Hospital,Fudan University were enrolled.The pediatric patients were randomly divided into hydro-morphine group(n=30)and esketamine group(n=30).Anesthesia induction:lidocaine 1.5 mg/kg,propofol 2.5 mg/kg and remifentanil 4 μg/kg were injected intravenously,and then the endotracheal tube was used for airway management.Anesthesia maintenance:remifentanil infusion was at 0.2-0.5 μg·kg-1·min-1 and the end tidal concentration of sevoflurane was at 0.7-1.0 minimum alveolar concentration(MAC).At the end of surgery,either hydromorphone 0.01 mg/kg or esketamine 0.5 mg/kg were administered for postoperative pain control.Time to resume spontaneous breathing was recorded.Other parameters included respiratory rate per minute,duration of stay in the post-anesthesia care unit,hemodynamic profiles.The adverse events including agitation and desaturation were also of note.Results Children in esketamine group resumed spontaneous breathing faster(P=0.048),had faster respiratory rate when recovery of spontaneous breathing(P=0.001)and lower concentration of end tidal CO2(P=0.005).The findings suggested that esketamine did not impair respiratory function.Compared to hydro-morphine group,children in esketamine group had shorter stay in the post-anesthesia care unit with statistical difference(P=0.020).Esketamine had no effect on heart rate and blood pressure,so there were less adverse events.Conclusion Compared with 0.01 mg/kg hydro-morphine,0.5 mg/kg esketamine does not impair respiratory function and it facilitate fast recovery in children undergoing endoscopic adenoidectomy after general anesthesia.

AIM:To investigate the effect of 3% diquafosol sodium eye drops combined with intense pulsed light on the treatment of meibomian gland dysfunction and the change of meibomian glands.METHODS: Prospective study. A total of 141 patients(282 eyes)who were diagnosed with meibomian gland dysfunction from January 2021 to May 2022 in our hospital were selected and they were randomly divided into the control group(73 cases, 146 eyes)and the observation group(68 cases, 136 eyes)according to random number table. The control group was given 0.3% sodium hyaluronate eye drops combined with intense pulsed light, and the observation group was treated with 3% diquafosol sodium eye drops combined with intense pulsed light. The subjective symptom score, physical sign score, non-invasive tear break-up time, tear meniscus height, lipid layer thickness, and meibomian gland density before and after the treatment were compared between the two groups at 2wk after the end of treatment.RESULTS: There were no differences in the subjective symptom score, physical sign score, non-invasive tear break-up time, tear meniscus height, lipid layer thickness, and meibomian gland density between the two groups of patients before treatment(P&#x003E;0.05). After 2wk of treatment, the symptom scores and physical sign scores of patients in the two groups continued to decrease, non-invasive tear break-up time and lipid layer thickness continued to increase, and the meibomian gland density also increased. The tear meniscus height in the observation group increased, while the control group showed no significant changes. The observation group had better clinical indicators than the control group(P&#x003C;0.05). No obvious complications were observed in all patients.CONCLUSION: The combination of diquafosol sodium eye drops and intense pulsed light is synergistic in the treatment of meibomian gland dysfunction, with significant therapeutic effects and improvement of meibomian gland repair, which is significantly superior to simple intense pulsed light therapy.

Clinicopathological and prognostic features of subungual melanoma in situ / 中华病理学杂志

Objective: To investigate the clinicopathological characteristics, immunohistochemical profiles, molecular features, and prognosis of subungual melanoma in situ (SMIS). Methods: Thirty cases of SMIS were collected in Fudan University Shanghai Cancer Center, Shanghai, China from 2018 to 2022. The clinicopathological characteristics and follow-up data were retrospectively analyzed. Histopathologic evaluation and immunohistochemical studies were carried out. By using Vysis melanoma fluorescence in situ hybridization (FISH) probe kit, combined with 9p21(CDKN2A) and 8q24(MYC) assays were performed. Results: There were 8 males and 22 females. The patients' ages ranged from 22 to 65 years (median 48 years). All patients presented with longitudinal melanonychia involving a single digit. Thumb was the most commonly affected digit (16/30, 53.3%). 56.7% (17/30) of the cases presented with Hutchinson's sign. Microscopically, melanocytes proliferated along the dermo-epithelial junction. Hyperchromatism and nuclear pleomorphism were two of the most common histological features. The melanocyte count ranged from 30 to 185. Most cases showed small to medium nuclear enlargement (29/30, 96.7%). Pagetoid spread was seen in all cases. Intra-epithelial mitoses were identified in 56.7% (17/30) of the cases. Involvement of nailfold was found in 19 cases, 4 of which were accompanied by cutaneous adnexal extension. The positive rates of SOX10, PNL2, Melan A, HMB45, S-100, and PRAME were 100.0%, 100.0%, 96.0%, 95.0%, 76.9%, and 83.3%, respectively. FISH analysis was positive in 6/9 of the cases. Follow-up data were available in 28 patients, and all of them were alive without disease. Conclusions: SMIS mainly shows small to medium-sized cells. High melanocyte count, hyperchromatism, nuclear pleomorphism, Pagetoid spreading, intra-epithelial mitosis, nailfold involvement, and cutaneous adnexal extension are important diagnostic hallmarks. Immunohistochemistry including SOX10 and PRAME, combined with FISH analysis, is valuable for the diagnosis of SMIS.

Clinicopathological features and prognosis of high-grade B-cell lymphoma with MYC and bcl-2 and/or bcl-6 rearrangements / 中华病理学杂志

Objective: To investigate the clinicopathological characteristics and prognosis of high-grade B-cell lymphoma (HGBL) involving combined rearrangements of MYC, bcl-2 and bcl-6. Methods: A total of 1 138 cases of large B cell lymphoma (LBL) that were treated at the Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine from January 2017 to September 2020 were analyzed using fluorescence in situ hybridization (FISH) with probes against MYC, bcl-2 and bcl-6. The clinical and pathological data of the 45 patients with HGBL that had rearrangements of MYC and bcl-2 and/or bcl-6 were collected and retrospectively analyzed. Results: Among the 1 138 LBL, 45 (4.0%) cases had combined rearrangements of MYC, bcl-2 and/or bcl-6 that included 6 HGBL cases with MYC, bcl-2 and bcl-6 rearrangements, 14 HGBL cases with MYC and bcl-2 rearrangements, and 25 HGBL cases with MYC and bcl-6 rearrangements. Of these 45 patients, 29 patients were male, and 16 patients were female, aged 29 to 83 years. HGBL with MYC, bcl-2 and bcl-6 rearrangements and HGBL with MYC and bcl-2 rearrangement were reclassified as the germinal center B-cell (GCB) subtype using the Hans algorithm. HGBL with MYC and bcl-6 rearrangement were reclassified as the GCB subtype (68.0%) and the non-GCB subtype (32.0%). The vast majority of HGBL cases had a high Ki-67 proliferation index. Most HGBL patients had advanced stage disease with a high IPI score and an increased LDH level. Also, some patients had clinical features including elevated plasma β2-microglobulin levels, B symptoms, and bone marrow involvement. The IPI scores and LDH levels were significantly different between the HGBL cases with MYC, bcl-2 and bcl-6 rearrangements and the HGBL cases with MYC and bcl-6 rearrangements (P<0.05). Compared with the HGBL cases with MYC, bcl-2 and bcl-6 rearrangements, the HGBL cases with MYC and bcl-2 or bcl-6 rearrangements had a lower incidence of bone marrow involvement (P<0.05). There were no significant differences in the prognosis among HGBL cases with MYC, bcl-2 and bcl-6 rearrangements, the cases with MYC and bcl-2 rearrangements, and the cases with MYC and bcl-6 rearrangements (P>0.05). Conclusions: HGBL with MYC, bcl-2 and/or bcl-6 rearrangements are rare types of B-cell lymphoma with high degree of malignancy and have a short overall survival. To reduce misdiagnosis and improve diagnostic accuracy, it is necessary to assess the patients' clinical features and conduct histopathological, immunohistochemical and FISH analyses.

【Objective】 To explore the mechanism of Yougui Pills in the treatment of knee osteoarthritis （KOA） based on network pharmacology and molecular docking. 【Methods】 The active components of Yougui Pills were obtained by searching TCMSP database. With the active component targets predicted by TCMSP， SwissTargetPrediction and TargetNet， we searched TCMIP， CTD， DisGeNET and GeneCards databases for KOA related targets. By crossing the two sets of targets， we obtained therapeutic targets of Yougui Pills for KOA. FDA-approved drugs for KOA and their targets were searched in the DrugBank database， and the drug-target network was constructed by using Cytoscape. Then the protein-protein interaction （PPI） network was constructed by using STRING database. After Go and KEGG enrichment analyses， the network of “traditional Chinese Medicine-active components-key targets-significant pathways-biological process” was constructed. 【Results】 A total of 132 active components were obtained from the nine herbal medicines of Yougui Pills， corresponding to 490 targets， of which 76 were potential therapeutic targets. Of them 13 were the same as the targets of 5 Western medicines for KOA. We screened out 18 key targets by the PPI network. Go enrichment analysis revealed 1281 biological processes， 60 molecular functions， and 17 cellular components， which were mainly related to inflammation， infection and oxidative stress. KEGG enrichment analysis showed that 50 pathways were significantly enriched， including IL-17 signaling pathway and TNF signaling pathway， whose functions were mainly involved in immune system， signal transduction， endocrine system， cell growth and death and other biological processes. 【Conclusion】 With multiple compounds acting on multiple molecular targets， Yougui Pills can treat KOA through molecular mechanisms including inhibiting inflammation， reducing oxidative stress， and promoting cartilage cell proliferation.

Study on the molecular mechanism of Cinnamomi Cortex-Rehmanniae Radix in preventing and treating osteoporosis based on multi-directional regulation of inflammatory factors, estrogen and bone homeostasis / 药学学报

In this study, the molecular mechanism of Cinnamomi Cortex-Rehmanniae Radix (CR) in the prevention and treatment of osteoporosis (OP) was investigated by integrating compatibility analysis of compound, bioinformatics and metabolomics. The rat OP models were established, and the Micro-CT indexes and pathological sections were comprehensively evaluated. The results showed that compared with the model group, the indexes such as bone mineral density (BMD) and bone volume/tissue volume (BV/TV) were significantly increased after CR treatment (P < 0.05), and the bone trabeculae were arranged into mesh. The results of UHPLC-Q-TOF/MS mainly involved amino acid metabolism, lipid metabolism and estrogen metabolism pathways. Integrating bioinformatics and metabolomics analysis, it was finally found that: ① cinnamic acid and ethylcinnamate inhibit inflammatory factors such as TNF, IL-1β, and IL-13, thereby preventing and treating OP; ② multiple active ingredients of CR target ESR2, PPARG, and CYP19A1, GABRA1 and other targets, regulate cAMP synthesis, AMPK signaling pathway and lipid metabolism, thereby regulating estrogen levels to prevent and treat OP; ③ oleic acid, arachic acid, etc. act on AR, VDR and other targets, and regulate HIF-1 signaling pathway and AGE-RAGE signaling pathway, thereby regulating osteoblasts and osteoclasts, and affecting calcium and phosphorus absorption to maintain bone homeostasis. This study clarified the molecular mechanism of CR in preventing and treating OP from the perspective of multi-directional regulation of inflammatory factors, estrogen and bone homeostasis, and provided theoretical basis for the clinical application of CR and the development of compound. This experiment complied with the ethical standards of animal experiments and was approved by the Animal Ethics Committee of Shaanxi University of Chinese Medicine (No. SUCMDL20210309002).

Complete plastid genomes of Bupleurum chinense DC. and B. boissieuanum H. Wolff, with comparative and phylogenetic analyses of medicinal Bupleurum species / 药学学报

italic>Bupleurum L. (Apiaceae) is an economically important genus, in which many species are of medicinal value. In this study, the complete plastid genomes (plastomes) of B. chinense DC. and B. boissieuanum H. Wolff were sequenced and their characteristics were investigated. Comparative and phylogenetic analyses were conducted with other published Bupleurum plastomes. The complete plastomes of B. chinense and B. boissieuanum were 155 458 and 155 800 bp in length, and both exhibited the typical quadripartite circular structure consisting of a large single copy region (LSC, 85 343 and 85 804 bp), a small single copy region (SSC, 17 495 and 17 410 bp), and a pair of inverted repeat regions (IRa/b, 26 310 and 26 293 bp), respectively. A total of 129 genes, including 84 protein-coding genes, 37 transfer RNA (tRNA) genes, and eight ribosomal RNA (rRNA) genes were identified from each of the two plastomes. Repeat sequences detected were similar in types and distribution patterns, but the numbers were slightly different. Comparative analyses revealed that the Bupleurum plastomes were highly conserved in length, structure, the guanine and cytosine (GC) content, and gene content and order, both intraspecifically and interspecifically, and no obvious expansion or contraction of the inverted repeat regions occurred. Sequence variation was lower within the same species than among different species, noncoding sequences (including intergenic regions and introns) showed a higher divergence than the protein-coding sequences, and sequences in the LSC and SSC regions were more divergent than those in the IR regions. In addition, 11 sequences with higher nucleotide diversity among species were detected in the LSC and SSC regions. All studied Bupleurum species were inferred forming a monophyletic group with a 100% bootstrap value. Bupleurum chinense and B. boissieuanum were phylogenetically closest to B. commelynoideum and B. falcatum, separately, with all three B. chinense accessions clustered into a distinct clade. These results provide genetic information for further species identification, phylogenetic resolution, and will assist in exploration and utilization of medicinal Bupleurum species.

Design and application of intra-abdominal pressure measuring device for children on peritoneal dialysis / 中华肾脏病杂志

Objective:To design an intra-abdominal pressure measuring device applied to children on peritoneal dialysis (PD), and evaluate the feasibility and safety of the application of the device.Methods:The device consisted of a three-way stopcock with extension tubing, a three-way stopcock, a manometer tube, and a "Y" system peritoneal dialysis bag. The intraperitoneal pressure of different fill volumes was measured when a child was supine and relaxed in a horizontal position. The subjects of the study were children who received PD at the Pediatric Hospital of Fudan University from May 2019 to February 2020 and had PD dialysis age of>1 month. The children's demographic and clinical information were collected. During the measurement, the child’s complaints of pain, bloating, vital signs, and catheter-related contamination were recorded. Additionally, the occurrence of dialysis-related infections and complications during the hospitalization and outcomes of PD after three months of the measurement were tracked. A scatter plot and Pearson correlation test were used to explore the correlation between fill volumes and the intraperitoneal pressure.Results:Nine PD children were included in our study. The age of the children was (8.4±4.7) years old. The body surface area is (0.84±0.29) m 2. The intraperitoneal pressure was (12.6±1.9) cmH 2O at the fill volume of 1 000 ml/m 2 and (13.8±1.9) cmH 2O at the fill volume of 1 200 ml/m 2. The measurement was smoothly and safely taken without any case of contamination and dialysis-related infections during the hospitalization. After three months of the measurement, one child was transferred to temporary hemodialysis due to the aggravation of the umbilical hernia. Conclusions:The intraperitoneal pressure measuring device is feasible and safe to perform among children with PD. It can achieve non-invasive and continuous measurement of intra-abdominal pressure, and has guiding significance for the dialysis prescription of children with PD.

Clinical features of neonatal enterovirus infection / 中国当代儿科杂志

OBJECTIVE@#To study the clinical features of neonatal enterovirus infection, especially severe enterovirus infection.@*METHODS@#A retrospective analysis was performed for the clinical data of 244 neonates with enterovirus infection. According to the severity of infection, they were divided into a common infection group with 231 neonates and a severe infection group with 13 neonates. Clinical features were compared between the two groups.@*RESULTS@#Of the 244 neonates, 207 (84.8%) developed the disease in May to October, with the highest number of patients in June to July. Compared with the common infection group, the severe infection group had a significantly lower gestational age at birth and a significantly higher proportion of preterm infants (P<0.05). Compared with the common infection group, the severe infection group had a significantly earlier onset time (P<0.05) and significantly higher incidence rates of skin petechiae and ecchymosis, respiratory symptoms, sepsis-like manifestations (poor appetite, crying less, and less movement), concomitant diseases (such as pneumonia, myocarditis, necrotic hepatitis, and coagulation disorder), thrombocytopenia, prolonged prothrombin time, elevated creatine kinase-MB, and elevated alanine aminotransferase (P<0.05). The severe infection group had a significantly higher mortality rate than the common infection group (P<0.05).@*CONCLUSIONS@#There are significant differences in onset time, common clinical manifestations, and concomitant diseases between the neonates with common and severe enterovirus infection. In the enterovirus epidemic season, if the neonates have rashes and/or sepsis-like manifestations such as poor appetite and less movement, especially if the laboratory tests suggest liver damage and coagulation dysfunction, it is necessary to pay particular attention to the possibility of severe enterovirus infection.

The results showed that 51 active components of Taohechengqi decoction may regulate 15 key targets such as nitric oxide synthase, endothelial (NOS3), prostaglandin G/H synthase 2 (PTGS2), matrix metalloproteinase-9 (MMP9), affecting vascular endothelial growth factor signaling pathway and other pathways to play a role in the prevention of stroke, affecting tumor necrosis factor signaling pathway and other pathways to play a role in the treatment of stroke. GEO data analysis showed that androgen receptor (AR), caspase-8 (CASP8), intercellular adhesion molecule 1 (ICAM1), interleukin-1 beta (IL1B), mitogen-activated protein kinase 14 (MAPK14), MMP9, myeloperoxidase (MPO), peroxisome proliferator-activated receptor gamma (PPARG), PTGS2 and cellular tumor antigen p53 (TP53) were up-regulated genes, while serum albumin (ALB), estrogen receptor 1 (ESR1), NOS3, transcription factor p65 (RELA) and proto-oncogene tyrosine-protein kinase Src (SRC) were down-regulated genes. GEO analysis explained that Taohechengqi decoction may prevent stroke by down-regulating ESR1, NOS3, and treat stroke by up-regulating ICAM1, IL1B, MAPK14, MMP9, PPARG, PTGS2, TP53, and down-regulating RELA and SRC. The study found that in the process of prevention and treatment of stroke, Taohechengqi decoction played a two-way regulation role through multi-genes and multiple ways, which provided a new strategy for the treatment of stroke.
