ABSTRACT

Objective: To analyze the clinical characteristics and prognosis of patients with infant acute lymphoblastic leukemia (IALL). Methods: A retrospective cohort study.Clinical data, treatment and prognosis of 28 cases of IALL who have been treated at Beijing Children's Hospital, Capital Medical University and Baoding Children's Hospital from October 2013 to May 2023 were analyzed retrospectively. Based on the results of fluorescence in situ hybridization (FISH), all patients were divided into KMT2A gene rearrangement (KMT2A-R) positive group and KMT2A-R negative group. The prognosis of two groups were compared. Kaplan-Meier method and Log-Rank test were used to analyze the survival of the patients. Results: Among 28 cases of IALL, there were 10 males and 18 females, with the onset age of 10.9 (9.4,11.8) months. In terms of immune classification, 25 cases were B-ALL (89%), while the remaining 3 cases were T-ALL (11%). Most infant B-ALL showed pro-B lymphocyte phenotype (16/25,64%). A total of 22 cases (79%) obtained chromosome karyotype results, of which 7 were normal karyotypes, no complex karyotypes and 15 were abnormal karyotypes were found. Among abnormal karyotypes, there were 4 cases of t (9; 11), 2 cases of t (4; 11), 2 cases of t (11; 19), 1 case of t (1; 11) and 6 cases of other abnormal karyotypes. A total of 19 cases (68%) were positive for KMT2A-R detected by FISH. The KMT2A fusion gene was detected by real-time PCR in 16 cases (57%). A total of 24 patients completed standardized induction chemotherapy and were able to undergo efficacy evaluation, 23 cases (96%) achieved complete remission through induction chemotherapy, 4 cases (17%) died of relapse. The 5-year event free survival rate (EFS) was (46±13)%, and the 5-year overall survival rate (OS) was (73±10)%.The survival time was 31.3 (3.3, 62.5) months. There was no significant statistical difference in 5-year EFS ((46±14)% vs. (61±18)%) and 5-year OS ((64±13)% vs. (86±13)%) between the KMT2A-R positive group (15 cases) and the KMT2A-R negative group (9 cases) (χ2=1.88, 1.47, P=0.170, 0.224). Conclusions: Most IALL patients were accompanied by KMT2A-R. They had poor tolerance to traditional chemotherapy, the relapse rate during treatment was high and the prognosis was poor.

ABSTRACT

This study investigated the effect of Lianmei Qiwu Decoction(LMQWD) on the improvement of cardiac autonomic nerve remodeling in the diabetic rat model induced by the high-fat diet and explored the underlying mechanism of LMQWD through the AMP-activated protein kinase(AMPK)/tropomyosin receptor kinase A(TrkA)/transient receptor potential melastatin 7(TRPM7) signaling pathway. The diabetic rats were randomly divided into a model group, an LMQWD group, an AMPK agonist group, an unloaded TRPM7 adenovirus group(TRPM7-N), an overexpressed TRPM7 adenovirus group(TRPM7), an LMQWD + unloaded TRPM7 adenovirus group(LMQWD+TRPM7-N), an LMQWD + overexpressed TRPM7 adenovirus group(LMQWD+TRPM7), and a TRPM7 channel inhibitor group(TRPM7 inhibitor). After four weeks of treatment, programmed electrical stimulation(PES) was employed to detect the arrhythmia susceptibility of rats. The myocardial cell structure and myocardial tissue fibrosis of myocardial and ganglion samples in diabetic rats were observed by hematoxylin-eosin(HE) staining and Masson staining. The immunohistochemistry, immunofluorescence, real-time quantitative polymerase chain reaction(RT-PCR), and Western blot were adopted to detect the distribution and expression of TRPM7, tyrosine hydroxylase(TH), choline acetyltransferase(ChAT), growth associated protein-43(GAP-43), nerve growth factor(NGF), p-AMPK/AMPK, and other genes and related neural markers. The results showed that LMQWD could significantly reduce the arrhythmia susceptibility and the degree of fibrosis in myocardial tissues, decrease the levels of TH, ChAT, and GAP-43 in the myocardium and ganglion, increase NGF, inhibit the expression of TRPM7, and up-regulate p-AMPK/AMPK and p-TrkA/TrkA levels. This study indicated that LMQWD could attenuate cardiac autonomic nerve remodeling in the diabetic state, and its mechanism was associated with the activation of AMPK, further phosphorylation of TrkA, and inhibition of TRPM7 expression.

ABSTRACT

On the basis of establishing the prescription of Xinjianqu and clarifying the increase of the lipid-lowering active ingredients of Xinjianqu by fermentation, this paper further compared the differences in the lipid-lowering effects of Xinjianqu before and after fermentation, and studied the mechanism of Xinjianqu in the treatment of hyperlipidemia. Seventy SD rats were randomly divided into seven groups, including normal group, model group, positive drug simvastatin group(0.02 g·kg~(-1)), and low-dose and high-dose Xinjianqu groups before and after fermentation(1.6 g·kg~(-1) and 8 g·kg~(-1)), with ten rats in each group. Rats in each group were given high-fat diet continuously for six weeks to establish the model of hyperlipidemia(HLP). After successful modeling, the rats were given high-fat diet and gavaged by the corresponding drugs for six weeks, once a day, to compare the effects of Xinjianqu on the body mass, liver coefficient, and small intestine propulsion rate of rats with HLP before and after fermentation. The effects of Xinjianqu before and after fermentation on total cholesterol(TC), triacylglyceride(TG), high-density lipoprotein cholesterol(HDL-C), low-density lipoprotein cholesterol(LDL-C), alanine aminotransferase(ALT), aspartate aminotransferase(AST), blood urea nitrogen(BUN), creatinine(Cr), motilin(MTL), gastrin(GAS), and the Na~+-K~+-ATPase levels were determined by enzyme-linked immunosorbent assay(ELISA). The effects of Xinjianqu on liver morphology of rats with HLP were investigated by hematoxylin-eosin(HE) staining and oil red O fat staining. The effects of Xinjianqu on the protein expression of adenosine 5'-monophosphate(AMP)-activated protein kinase(AMPK), phosphorylated AMPK(p-AMPK), liver kinase B1(LKB1), and 3-hydroxy-3-methylglutarate monoacyl coenzyme A reductase(HMGCR) in liver tissues were investigated by immunohistochemistry. The effects of Xinjianqu on the regulation of intestinal flora structure of rats with HLP were studied based on 16S rDNA high-throughput sequencing technology. The results showed that compared with those in the normal group, rats in the model group had significantly higher body mass and liver coefficient(P<0.01), significantly lower small intestine propulsion rate(P<0.01), significantly higher serum levels of TC, TG, LDL-C, ALT, AST, BUN, Cr, and AQP2(P<0.01), and significantly lower serum levels of HDL-C, MTL, GAS, Na~+-K~+-ATP levels(P<0.01). The protein expression of AMPK, p-AMPK, and LKB1 in the livers of rats in the model group was significantly decreased(P<0.01), and that of HMGCR was significantly increased(P<0.01). In addition, the observed_otus, Shannon, and Chao1 indices were significantly decreased(P<0.05 or P<0.01) in rat fecal flora in the model group. Besides, in the model group, the relative abundance of Firmicutes was reduced, while that of Verrucomicrobia and Proteobacteria was increased, and the relative abundance of beneficial genera such as Ligilactobacillus and Lachnospiraceae_NK4A136_group was reduced. Compared with the model group, all Xinjianqu groups regulated the body mass, liver coefficient, and small intestine index of rats with HLP(P<0.05 or P<0.01), reduced the serum levels of TC, TG, LDL-C, ALT, AST, BUN, Cr, and AQP2, increased the serum levels of HDL-C, MTL, GAS, and Na~+-K~+-ATP, improved the liver morphology, and increased the protein expression gray value of AMPK, p-AMPK, and LKB1 in the liver of rats with HLP and decreased that of LKB1. Xinjianqu groups could regulate the intestinal flora structure of rats with HLP, increased observed_otus, Shannon, Chao1 indices, and increased the relative abundance of Firmicutes, Ligilactobacillus(genus), Lachnospiraceae_NK4A136_group(genus). Besides, the high-dose Xinjianqu-fermented group had significant effects on body mass, liver coefficient, small intestine propulsion rate, and serum index levels of rats with HLP(P<0.01), and the effects were better than those of Xinjianqu groups before fermentation. The above results show that Xinjianqu can improve the blood lipid level, liver and kidney function, and gastrointestinal motility of rats with HLP, and the improvement effect of Xinjianqu on hyperlipidemia is significantly enhanced by fermentation. The mechanism may be related to AMPK, p-AMPK, LKB1, and HMGCR protein in the LKB1-AMPK pathway and the regulation of intestinal flora structure.

ABSTRACT

Objective: To evaluate the effect of inactivated SARS-CoV-2 vaccine on the clinical outcomes of patients infected with the Omicron variant. Methods: A total of 1 403 Omicron-infected patients admitted to 20 designated hospitals in Guangdong Province from January 1 to May 31, 2022, were selected as subjects in this study. A case-control study was conducted to collect the demographic data, underlying disease, vaccination status, last exposure date, gene sequencing of infected strains and clinical outcomes from the China Disease Prevention and Control Information System and Guangdong telemedicine platform. Pneumonia (common, severe and critical) and non-pneumonia (asymptomatic and mild) were selected as the case group and control group. The effect of inactivated SARS-CoV-2 vaccine on the clinical outcomes of patients infected with the Omicron variant was analyzed. Results: The median age [M (Q1, Q3)] of the subjects was 36 (27-47) years old, with males accounting for 52.25% (733 cases). The main outcome of the infection was non-pneumonia, accounting for 92.09% (1 292 cases), and the duration [M (Q1, Q3)] of the disease was 18 (14-22) days. There were 134 (9.55%), 39 (2.78%), 403 (28.72%), 437 (31.15%) and 390 (27.80%) cases with no or partial vaccination, within 90 days of primary vaccination, over 90 days of primary vaccination, within 90 days of booster vaccination and over 90 days of booster vaccination, respectively. Multivariate logistic regression analysis showed that after adjusting for gender, age, underlying disease, and location of the report, compared with those with no or partial vaccination, the risk of developing pneumonia was lower in those with over 90 days of primary vaccination, within 90 days of booster vaccination and over 90 days of booster vaccination [OR (95%CI) values were 0.52 (0.28-0.98), 0.39 (0.21-0.73) and 0.40 (0.21-0.77), respectively]. Cox proportional hazard regression model analysis showed that after adjusting for gender, age, underlying disease and location of the report, the duration of the disease was shorter in those who received booster vaccinated for more than 90 days compared with that in those who had no or partial vaccination [HR (95%CI): 1.26 (1.03-1.55)]. Conclusion: The inactivated SARS-CoV-2 vaccine affects the clinical outcomes of patients infected with the Omicron variant.

ABSTRACT

OBJECTIVE@#To investigate the in vivo intervention and relative mechanism of Genistein (GEN) on tumor-associated inflammatory and tumor thrombophilia in lymphoma-bearing mice.@*METHODS@#Forty female Balb/c mice aged 5-6 weeks were injected with murine-derived Pro B-cell lymphoma cell line 38B9 to establish a lymphoma mouse model, which was randomly divided into control group, tumor-bearing group, GEN drug intervention group and cyclophosphamide (CTX)drug intervention group. Histopathologic was used to evaluate the tumorigenesis. Tumor formation was observed, and tumor tissues were collected of HE and immunohistochemical staining. ELISA and flow cytometry were used to detect the expression of inflammatory factors and the changes of thrombus indices in plasma after intervention of GEN and Cyclophosphamide (CTX) respectively. Immunohistochemistry method was used to detect the expression of CD19 in tomor tissues of tummor bearing mice.@*RESULTS@#After 14 days of tumor bearing, the mice were tumorigenic. The lymphoma cells were diffusely distributed in the tumor tissue and the expression of CD19 in the tumor tissue was positive. The inflammatory factors such as IL-6, NETs and CLEC-2, and thrombotic indices such as TF, FIB and D-D in lymphoma-bearing mice were significantly higher than those before tumor-injection and lower than those after drug-intervention (all P<0.05). The levels of CLEC-2 and D-D in GEN group were significantly lower than those in CTX group (P<0.05).@*CONCLUSION@#Tumor-associated inflammation and thrombophilia exist in lymphoma-bearing mice. GEN shows better anti-inflammatory and anti-thrombotic effects compared with CTX by interfering with tumor inflammatory factors.

ABSTRACT

Abstract: Background: It is challenging to make informed decision in genetic counseling. Shared decision-making provides a chance in balancing the information and preferences between counselors and counselees. However, the status and prescriptions of shared decision-making have not been extensively studied in genetic counseling. Aim: To develop an up-to-date literature review of the shared decision-making in genetic counseling, identify knowledge gaps, and provide inspiration and suggestions for the development and practice of genetic counseling. Methods: "Genetic Counseling" and "Shared decision-making" were used to search in PubMed, Web of Science, Embase, Wanfang, CNKI and CBM databases. The search deadline was March 26, 2021. Results: A total of 22 articles were included, and four themes were identified: how people involved in genetic counseling, different stakeholders involved in SDM, multiple facilitators and barriers to SDM and the effectiveness of SDM in genetic counseling. Conclusion: Each participant needs to recognize their boundaries and make the best effort to involve in the shared decision-making. In the future, multinational studies should be considered for bringing shared decision-making to the global scale and well-designed studies are required to explore the long-term impact of shared decision-making in genetic counseling.

ABSTRACT

OBJECTIVES@#To study the clinical manifestations and gastroscopic characteristics of upper gastrointestinal ulcer in children.@*METHODS@#A retrospective analysis was performed for the children who underwent gastroscopy and were found to have upper gastrointestinal ulcer for the first time at the Endoscopy Center of Shengjing Hospital, China Medical University, from January 2011 to May 2021. According to the cause of the disease, they were divided into primary ulcer group (primary group; n=148) and secondary ulcer group (secondary group; n=25). The clinical data were compared between the two groups.@*RESULTS@#A total of 173 children with upper gastrointestinal ulcer were enrolled, with a male/female ratio of 3.9:1. Compared with girls, boys had significantly higher proportions of duodenal ulcer and primary ulcer (P<0.05). Compared with the children aged below 6 years, the children aged 6-14 years had higher proportions of duodenal ulcer and primary ulcer and lower proportions of giant ulcer and multiple ulcers. Of the 148 children in the primary group, 95 (64.2%) had Helicobacter pylori infection. Abdominal pain was the most common clinical symptom and was observed in 101 children (68.2%). Duodenal ulcer was common and was observed in 115 children (77.7%), followed by gastric ulcer in 25 children (16.9%) and esophageal ulcer in 7 children (4.7%). Multiple ulcers were observed in 32 children (21.6%). Seventy children (47.3%) experienced complications, among which bleeding was the most common complication and was observed in 63 children (43.6%). Of the 25 children in the secondary group, abdominal pain was the most common clinical symptom and was observed in 9 children (36.0%), with a significantly lower incidence rate than the primary group (P<0.05); foreign body in the digestive tract was the most common cause of ulcer and was observed in 17 children (68%), followed by abdominal Henoch-Schönlein purpura in 5 children (20.0%) and Crohn's disease in 3 children (12.0%). The secondary group had a significantly higher proportion of multiple ulcer or giant ulcer than the primary group (P<0.05).@*CONCLUSIONS@#Upper gastrointestinal ulcer is more common in boys than girls, and duodenal ulcer and primary ulcer are more common in boys. Children aged 6-14 years often have duodenal ulcer and primary ulcer, and giant ulcer and multiple ulcers are relatively uncommon. Primary ulcer in children has a variety of clinical manifestations, mainly abdominal pain, and duodenal ulcer is relatively common, with bleeding as the main complication. The clinical symptoms and endoscopic manifestations of secondary ulcer are closely associated with the primary causes, and it is more likely to induce huge ulcers and multiple ulcers.

ABSTRACT

OBJECTIVE@#To investigate the potential inhibitory effect of interference with PD-L1 on B cell lymphoma in mice.@*METHODS@#Three shRNA vectors for mouse CD274 (PD-L1) were constructed and transiently transfected into 293T cells. RT-qPCR was used to validate the interference efficiency of CD274. The shRNA vector that interfere efficiently with CD274 expression was packaged by using lentivirus packaging system to generate shRNA lentivirus, and then transfected into A20 lymphoma cell line. The methyl thiazol terazolium (MTT) assay was used to detect proliferation after 48 h culture of CD274-sh A20 cells. Meanwhile, BALB/c mice were hypodermically infected with CD274-sh A20 cells. Infected mice were observed daily and assessed to visualize tumor by in vivo fluorescence imaging.@*RESULTS@#The proliferation rate of CD274-sh A20 cells in vitro was significantly lower than that of A20 cells (P<0.05). The tumor size detected by in vivo fluorescence imaging showed a significant reduce in tumor bearing mice with CD274-sh compared with other tumor bearing mice. And the weight and size of tumor in CD274-sh group were also significantly reduced compared with other group (P<0.05). Moreover, the survival time of tumor bearing mice in CD274-sh group was longer than that of the PD-L1 high expression group.@*CONCLUSION@#PD-L1 plays an important role in the incidence and the progression of lymphoma, and the shRNA-based PD-L1 knockdown can inhibit cell proliferation of A20 cells and partly suppress tumor growth.

ABSTRACT

Objective:To investigate the clinical manifestations, risk factors and outcomes of patients with acute cingulate cortex (CC) infarction.Methods:Patients with acute CC infarction admitted to the Department of Neurology, the First Affiliated Hospital of Nanjing Medical University from December 2019 to April 2022 were enrolled retrospectively. According to the location of infarction, they were divided into anterior cingulate cortex (ACC) infarction group and posterior cingulate cortex (PCC) infarction group. The clinical manifestations, stroke risk factors, imaging examination and National Institutes of Health Stroke Scale (NIHSS) score of the patients were analyzed. At one month after onset, the modified Rankin Scale was used to evaluate the short-term outcome.Results:A total of 21 patients with acute CC infarction were enrolled, including 12 males (57.14%), aged 67.14±12.36 years (range, 45-89 years). There were 16 patients (76.19%) with ACC infarction, including 13 (81.25%) unilateral CC infarction. The clinical manifestations were mainly apathy, decreased concentration, and executive dysfunction. There were 5 patients (23.81%) with PCC infarction, all with unilateral onset, mainly manifested as memory loss and visual space disorder. Among the 21 patients, 18 (85.71%) had ≥2 vascular risk factors, and 13 patients (61.90%) had ≥3 vascular risk factors, of which hypertension was most common (90.48%); 19 (90.48%) were caused by atherosclerosis, and 2 (9.52%) were caused by cardiogenic embolism. After treatment, the symptoms of both groups were improved significantly, and there was statistical difference in the NIHSS score before and after treatment ( Z=4.07, P<0.01). During the follow-up, 16 patients (76.19%) had a good outcome, 5 (23.81%) had a poor outcome and no death occurred. Conclusions:ACC and PCC infarction mainly showed different forms of cognitive impairment. If the diagnosis and treatment are timely, the overall outcome of CC infarction is good.

ABSTRACT

Orbital lymphomas (OLs) are the common malignant tumor of the ocular adnexa.According to the source of abnormally proliferating lymphocytes, OLs can be further divided into several subtypes.The etiology and pathogenesis of OLs are still controversial.The current researches on OLs have shown that the etiology and pathogenesis of the disease are mainly related to genetic abnormalities of lymphocytes, abnormal immunosuppression, autoimmune diseases and chronic antigenic stimulation.However, there is no real lymphatic drainage system in the eye.Only a mucosa-associated lymphoid tissue (MALT) system extends from the lacrimal glands to the conjunctiva and lacrimal duct, so the pathogenesis of OLs is still unique.And the etiology of different OLs subtypes is quite different.For example, different chromosomal aberrations can cause varying subtypes of OLs, and various OLs subtypes have diverse predispositions in different autoimmune diseases.Researches on the etiology and pathogenesis of OLs at home and abroad were reviewed in this article to provide a reference for its clinical diagnosis and treatment.

ABSTRACT

Pediatric acute liver failure(PALF)is a severe liver damage caused by multiple factors, resulting in severe impairment of hepatic synthesis, excretion, detoxification and biotransformation.It was thought that PALF patients had coagulation disorders that predisposed them to bleeding.Now it is noted that due to the simultaneous reduction of anticoagulant and procoagulant factors, the body is in a state of rebalanced hemostasis.The risk of thrombosis is nearly equal to hemorrhage.Appropriate laboratory tests can better assess the coagulation status of children with PALF and guide appropriate blood product transfusions to improve coagulation and reduce the risk of transfusion-related fluid overload and other adverse prognosis.

ABSTRACT

Objective:Non-alcoholic fatty liver disease (NAFLD) is not only a liver manifestation of metabolic syndrome, but also related to type 2 diabetes, dyslipidemia and hypertension closely. This study aims to explore the correlation between clinical and experimental indexes and disease occurrence in patients with NAFLD combined with essential hypertension.Methods:One hundred and thirty-four patients with NAFLD combined with essential hypertension and 98 patients in the control group were enrolled in this study from March 2019 to March 2021 in Dalian Central Hospital. The clinical baseline and test indexes of the two groups were compared and analyzed, and the logistic regression analysis was also performed.Results:The mean and median values of alanine aminotransferase, γ-glutamyl transpeptidase, lactate dehydrogenase and triacylglycerol in the experimental group were higher than those in the control group: 22 U/L vs. 17 U/L, 23 U/L vs. 17 U/L, 179 U/L vs. 173 U/L, 1.68 mmol/L vs. 1.45 mmol/L, while the mean and median values of homocysteine, albumin (ALB), creatinine and free triiodothyronine were lower than that in the control group: 11.2 μmol/L vs. 12.2 μmol/L, 41.5 g/L vs. 43.5 g/L, 54 μmol/L vs. 60 μmol/L, (4.657 ± 0.599) pmol/L vs. (4.850 ± 0.574) pmol/L ( P<0.05). Multivariate Logistic regression analysis showed that BMI, diabetes and ALB were independently correlated with NAFLD. Conclusions:The BMI and diabetes were independent risk factors for NAFLD in patients with essential hypertension, and ALB is an independent protective factor.

ABSTRACT

Objective: To explore the effect of perioperative airway management based on the concept of enhanced recovery after surgery (ERAS) on the improvement of preoperative pulmonary function in patients with aspirin intolerance triad (AIT). Methods: Thirty patients with AIT (including 13 males and 17 females, aged from 29 to 75 years old) for sinus surgery from January 2018 to December 2019 were selected, 172 patients (including 105 males and 67 females, aged from 17 to 83 years old) with chronic rhinosinusitis with nasal polyps (CRSwNP) without lower airway disease were selected by random number table at the same period, and their clinical data and preoperative pulmonary function were analyzed and compared retrospectively. FEV1%pred<80% after bronchodilation test was considered as high risk for surgery. Preoperative evaluation and standardized drug intervention were applied in patients with pulmonary function abnormalities at risk for surgery, and improvement of preoperative pulmonary function and tolerability to general anesthesia surgery in the two groups were evaluated. All the statistical analyses were conducted using SPSS 22.0. Results: The main pulmonary function indexes (FEV1%pred, FEV1/FVC%pred, FEF50%pred, FEF75%pred, MMEF%pred) in AIT group decreased significantly than those in CRSwNP group (t values were 10.882, 10.506, 9.141, 10.182, 9.099, respectively, all P<0.001). At admission 86.7% (26/30) patients in the AIT group and 11.6% (20/172) patients in CRSwNP group had high surgical risk for lung function, with significantly difference (χ2 = 81.788, P<0.05); after 3 days with individualized drug intervention, 57.7% (15/26) patients in AIT group reached the standard for surgery, which was significantly less than 90.0% (18/20) patients in CRSwNP group (χ²=4.335,P<0.05); and after 6 days with drug intervention, the patients who reached the standard for surgery in pulmonary function accounted for 92.3% (24/26) in the AIT group and 100% (20/20) in the CRSwNP group. FEV1%pred in the two groups before surgery were significantly improved compared with those at admission respectively ((90.00±6.32)% vs. (64.79±13.60)%,t value was 10.110 in AIT group; (91.65±11.86)% vs. (76.40±9.35)%, t value was 9.346 in CRSwNP group; all P<0.05), and also FEV1/FVC%pred, FEF50%pred, FEF75%pred and MMEF%pred were all significantly improved (all P<0.05). Surgery was completed successfully in the two groups of patients with lung function meeting the surgical standard, and no intraoperative or postoperative airway adverse events occurred. Conclusion: AIT patients have high airway risk for sinus surgery due to poor pulmonary function. Standardized airway management based on the concept of ERAS can improve the pulmonary function of patients, and decrease the incidence of perioperative airway adverse events.
