OBJECTIVE: To analyze the gene mutation characteristics and survival time of patients with newly diagnosed acute myeloid leukemia (AML) based on next-generation sequencing(NGS) gene detection. METHODS: A retrospective analysis was conducted on the clinical data of 92 patients with AML (non APL) admitted to our hospital from January 2018 to May 2022. AML related genes tested were using NGS, the mutation characteristics and survival time of AML patients were analyzed. RESULTS: Among the 92 patients, 41 were males and 51 were females. A total of 38 types of gene mutations were detected. Six-two patients carried at least one gere mutation, while no gene mutations were detected in 30 patients. In the group with favourable prognosis (n =14), the frequencies of higher gene mutations were NRAS, KIT (21.43%, n =3), KRAS (14.29%, n =2). In the group with intermediate prognosis (n =64), the gene mutation frequencies from high to low were DNMT3A (18.75%, n =12), NPM1 (17.19%, n =11), IDH2, FLT3-ITD, CEBPA (12.50%, n =8), TET2 (10.94%, n =7). In the poor prognosis group (n =14), ASXL1, TP53, EZH2, NRAS had higher gene mutation frequency than others(14.29 %, n =2 ). Statistical analysis revealed that KIT had a relative hotspot of mutations in the intermediate-risk group, and DNMT3A had a relative hotspot of mutations in the high-risk group (P < 0.05). The correlation analysis of genes with high mutation rates in different prognostic groups, such as NRAS, KIT, IDH2, DNMT3A, NPM1, and FLT3-ITD, with prognosis found that KIT was a factor affecting OS (P < 0.05), while no significant differences were observed for the others(P >0.05). CONCLUSION The frequency of gene mutations is high in AML patients, 67.4% of the patients carried at least one gene mutation. The mutation frequency varies among different genes in patients with different karyotypes, and there are obvious dominant mutations. KIT and DNMT3A can be used as factors for evaluating the prognosis of AML.

OBJECTIVE: To investigate the clinical features and prognostic factors of primary tonsil lymphoma (PTL). METHODS: The clinical data of 41 patients diagnosed with PTL and treated in the Affiliated Hospital of Xuzhou Medical University from January 2015 to December 2022 were collected and retrospectively analyzed. Their clinical features and prognostic factors were analyzed. RESULTS: All the 41 patients were newly diagnosed with PTL, and the median age of onset was 58(19-85) years. Among them, 19 patients started with pharyngeal pain, 12 patients presented with dysphagia, 8 patients presented with pharyngeal mass, and 2 patients presented with blurred articulation. The most common pathological type was diffuse large B-cell lymphoma (24 cases, 58.54%). All patients received chemotherapy, and 3 patients were combined with hematopoietic stem cell transplantation. Among 41 patients, 11 (26.83%) achieved complete response, 14 (34.15%) achieved partial response, and the total response rate was 60.98% (25/41). The median follow-up time was 37(6-107) months, the 5-year overall survival (OS) rate was 70.81% and 5-year progression-free survival (PFS) rate was 66.20%. Univariate analysis showed that B symptoms, Ki-67, β₂-MG and IPI score had significant effects on PFS and OS of patients (all P < 0.05). Multivariate analysis showed that IPI score was an independent risk factor for PFS and OS of patients (P < 0.05). CONCLUSION The clinical manifestations of PTL lack specificity, and the prognosis is relatively good. Most patients can achieve long-term survival after treatment. IPI score is related to the prognosis.

Objective To make an epidemiological investigation on traditional Chinese medicine(TCM)dampness syndrome manifestations in the population at risk of cerebrovascular diseases in Guangdong area.Methods A cross-sectional study was conducted to analyze the clinical data related to the risk of cerebrovascular diseases in 330 Guangdong permanent residents.The diagnosis of dampness syndrome,quantitative scoring of dampness syndrome and rating of the risk of stroke were performed for the investigation of the distribution pattern of dampness syndrome and its influencing factors.Results(1)A total of 306(92.73%)study subjects were diagnosed as dampness syndrome.The percentage of dampness syndrome in the risk group was 93.82%(258/275),which was slightly higher than that of the healthy group(48/55,87.27%),but the difference was not statistically significant(χ2 = 2.91,P = 0.112).The quantitative score of dampness syndrome in the risk group was higher than that of the healthy group,and the difference was statistically significance(Z =-2.24,P = 0.025).(2)Among the study subjects at risk of cerebrovascular disease,evaluation time(χ2 = 26.11,P = 0.001),stroke risk grading(χ2= 8.85,P = 0.031),and history of stroke or transient ischemic attack(TIA)(χ2 = 9.28,P = 0.015)were the factors influencing the grading of dampness syndrome in the population at risk of cerebrovascular disease.Conclusion Dampness syndrome is the common TCM syndrome in the population of Guangdong area.The manifestations of dampness syndrome are more obvious in the population with risk factors of cerebrovascular disease,especially in the population at high risk of stroke,and in the population with a history of stroke or TIA.The assessment and intervention of dampness syndrome should be taken into account for future project of stroke prevention in Guangdong.

Objective:To evaluate the efficacy of esketamine combined with propofol for colonic transendoscopic enteral tubing (TET) in pediatric patients with autism.Methods:Sixty pediatric patients with autism of both sexes, aged 3-12 yr, weighing 15-45 kg, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, who underwent painless transendoscopic enteral tubing (TET) from October 2022 to August 2023, were selected and divided into 2 groups ( n=30 each) by a random number table method: normal saline + propofol group (group NP) and esketamine + propofol group (group EP). In group NP, normal saline 10 ml was intravenously injected, and 30 s later propofol 2.0 mg/kg was given. In group EP, esketamine 0.3 mg/kg (diluted to 10 ml in normal saline) was intravenously injected, and 30 s later propofol 2.0 mg/kg was given. TET was performed when the Modified Observer′s Assessment of Alertness/Sedation Scale score ≤2. Propofol 0.5-1.0 mg/kg was added if the sedation depth was not enough, and the Modified Observer′s Assessment of Alertness/Sedation Scale score was maintained ≤2 until the end of surgery. The degree of body movement during TET was observed and recorded. The injection pain during induction, total consumption of propofol, operation time, spontaneous emergence time, and completion of operation were recorded. Adverse reactions such as respiratory depression, nausea and vomiting, hypotension, bradycardia, and postoperative agitation were recorded during operation and in the emergence period. Results:Compared with group NP, the degree of intraoperative body movement was significantly lighter, the total consumption of propofol and incidence of injection pain and intraoperative hypotension were significantly lower, and no significant change was found in the spontaneous emergence time and incidence of adverse reactions during recovery in group EP ( P<0.05). Conclusions:Esketamine (0.3 mg/kg) combined with propofol (2.0 mg/kg) can be safely and effectively used for colonic TET in pediatric patients with autism, and esketamine does not increase the risk of adverse reactions during resuscitation in a resuscitation strategy without early awakening.

ObjectiveOur recent study has demonstrated that extracellular acidification promotes lipid accumulation in macrophages via the activation of acid sensing ion channel 1 (ASIC1), but the underlying mechanism remains unclear. This study aims to explore the effect of extracellular acidification on macrophage lipophagy and the underlying mechanism. MethodsRAW264.7 macrophages were incubated with 25 mg/Lox-LDL in a pH 6.5 culture medium for 24 h to build macrophage-derived foam cell models induced by extracellular acidification. Then, RAW264.7 macrophages were cultured in the acidic medium of pH 6.5 with or without PcTx-1 (ASIC1 specific blocker, 10 μg/L) or Nec-1 (RIP1 specific inhibitor, 20 μmol/L) for 24 h, intracellular lipid accumulation was observed by oil red O staining. The expressions of total ASIC1, plasma membrane ASIC1, RIP1, p-RIP1 Ser166, TFEB, p-TFEB Ser142, LC3 and p62 were measured by Western blot. The co-localization of lipids (indicated by Bodipy) with LC3II (autophagosomes) and LAMP1 (lysosomes) was analyzed by a confocal laser scanning microscopy, respectively. Morphological changes of lipophagy in the cells were observed by using transmission electron microscopy. ABCA1-mediated cholesterol efflux was determined by cholesterol fluorescence kits. ResultsCompared with pH 7.4+ox-LDL group, the intracellular lipid accumulation in the pH 6.5+ox-LDL group was significantly increased. Meanwhile, the expressions of plasma membrane ASIC1, p-RIP1 Ser166, p-TFEB Ser142, and p62 proteins were elevated significantly, while LC3II protein level and LC3II/LC3I ratio were decreased. Accordingly, compared with pH 7.4+ox-LDL group, the macrophage lipophagy of the pH 6.5+ox-LDL group was inhibited as indicated by the decreased localization of lipid droplets with LC3 and LAMP1, a decrease in the number of lipophagosomes as well as an increase in lipid droplets. Furthermore, ATP binding cassette transporter A1 (ABCA1)-dependent cholesterol efflux from the macrophages of pH 6.5+ox-LDL group reduced dramatically. However, these above effects of extracellular acidification on RAW264.7 macrophages were abolished by PcTx-1 and Nec-1, respectively. ConclusionThese findings suggest extracellular acidification promotes the phosphorylation of TFEB at Ser142 via activating ASIC1/RIP1 pathway, thereby impeding lipophagy in RAW 264.7 macrophages, and that ASIC1 may be a new potential target for preventing aberrant lipid accumulation diseases including atherosclerosis.

Aim To investigate the effect of paeonol(PAE)on cardiac hypertrophy induced by Angio-tensinogen Ⅱ(Ang Ⅱ)in rats and its mechanism.Methods Forty Sprague-Dawley rats were divided in-to five groups:control group,Ang Ⅱ model group,low concentration paeonol group,middle concentration pae-onol group,high concentration paeonol group.PAE was administered intragastrically(25,50 and 100 mg·kg-1·d-1)for 28 days.The hypertrophic model was established by adding 1 μmol·L-1 Ang Ⅱ to H9c2 cells for 48 hours.Results In Ang Ⅱ-induced rats,PAE improved echocardiography parameters,the cardi-ac hypertrophy index,the mRNA and protein expres-sion levels of ANP and BNP were decreased,and the cardiac fibrosis was alleviated.In vitro,PAE reduced cardiomyocyte hypertrophy and decreased the mRNA and protein expression levels of ANP and BNP in H9c2 cells induced by Ang Ⅱ,at the same time,the expres-sion of endoplasmic reticulum stress marker proteins p-PERK,GRP78,ATF4 and CHOP were decreased and reversed after treatment with the endoplasmic reticulum stress agonist tunicamycin(TN).Conclusion This study suggests that PAE can improve cardiac hypertro-phy by inhibiting endoplasmic reticulum stress,which may be a new drug to delay the development of cardiac hypertrophy.

Objective To investigate the characteristics of gut flora related to dampness syndrome in the population at risk of cerebrovascular disease and to explore their influencing factors.Methods Based on the results of epidemiological investigation of damp syndrome in at-risk population of cerebrovascular disease in Guangdong from October 2021 to February 2023,60 subjects(including 41 at-risk cases of cerebrovascular disease and 19 healthy controls)were included in the study.The identification of dampness syndrome and the risk rating of stroke were carried out for the subjects,and fecal samples were collected.High-throughput 16S rRNA sequencing technology and bioinformatics methods were used to analyze the characteristics of gut flora.Results(1)A total of 53 cases(88.33％)were identified as dampness syndrome.There was significant difference in the quantitative score of dampness syndrome between the risk group and the healthy group,and between the low-,medium-and high-risk groups(P=0.016;P=0.041).(2)There was no statistical difference in the species and abundance of gut flora between the dampness syndrome group and the non-dampness syndrome group.(3)In the population identified as dampness syndrome,there was no significant difference in Alpha diversity between the healthy group and the risk group,but there was significant difference in Beta diversity analysis;LEfSe analysis found that Fusobacterium and Lactobacillus were enriched in the risk group;correlation analysis showed that the differential bacteria were related to the three risk factors of diabetes,dyslipidemia and obesity and carotid intima-media thickness(IMT).(4)In the population identified as dampness syndrome and having the risk of cerebrovascular disease,there was no significant difference in Alpha diversity among three groups with different levels of risks,while significant difference in Beta diversity was observed;LEfSe analysis showed that Acidaminococcaceae,Phascolarctobacterium and Butyricimonas were enriched in the low-risk group,Veillonellaceae was enriched in the medium-risk group,and Ruminococcus 2 and Alloprevotella were enriched in the high-risk group;correlation analysis showed that the differential bacteria were associated with high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C),white blood cell count(WBC),and neutrophil count(NEUT).Conclusion In the Guangdong population predominated by dampness syndrome,the severity of dampness syndrome is related to the risk of stroke,and the specific flora associated with sub-clinical atherosclerosis,inflammatory response and lipid metabolism are presented.

Background/Aims: The histological characteristics and natural history of precirrhotic primary biliary cholangitis (PBC) with portal hypertension (PH) are unclear. Our aim was to clarify the prevalence, risk factors, and histological characteristics of precirrhotic PBC patients with PH. Methods: This retrospective study compared the clinical features, histological characteristics, and response to ursodeoxycholic acid (UDCA) between the PH and non-PH groups of precirrhotic PBC patients. Results: Out of 165 precirrhotic PBC patients, 40 (24.2%) also had PH. According to histological stage 1, 2 and 3 disease, 5.3% (1/19), 17.3% (17/98), and 45.8% (22/48) of patients also had PH, respectively. Precirrhotic PBC with PH was significantly positively correlated with bile duct loss, degree of cytokeratin 7 positivity, and degree of fibrosis in the portal area, but significantly negatively correlated with lymphoid follicular aggregation. Compared to the non-PH group, patients in the PH group showed a higher prevalence of obliterative portal venopathy, incomplete septal fibrosis, portal tract abnormalities and non-zonal sinusoidal dilatation (p<0.05). In addition, patients with PH were more likely to present with symptoms of jaundice, ascites, epigastric discomfort, a poorer response to UDCA, and more decompensation events (p<0.05). High alkaline phosphatase levels, low white blood cell counts, high Mayo scores, and high FIB-4 index values were risk factors for precirrhotic PBC with PH. Conclusions Approximately 24.2% of precirrhotic PBC patients have PH, which is histologically related to the injury of bile ducts. High alkaline phosphatase levels, low white blood cell counts, high Mayo scores, and high FIB-4 index values are associated with increased risk of precirrhotic PBC with PH.
