Clinical characteristics and prognosis of 28 cases of infant acute lymphoblastic leukemia / 中华儿科杂志

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.

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.

Difference of lipid-lowering efficacy of "Xinjianqu" before and after fermentation and its mechanism based on LKB1-AMPK pathway and 16S rDNA sequencing technology / 中国中药杂志

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.

Lianmei Qiwu Decoction relieves diabetic cardiac autonomic neuropathy by regulating AMPK/TrkA/TRPM7 signaling pathway / 中国中药杂志

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.

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.

Advances in etiology and pathogenesis of orbital lymphoma / 中华实验眼科杂志

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.

Inhibitory Effect of Interference with PD-L1 Expression on B-cell lymphoma in Mice / 中国实验血液学杂志

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.

Head acupuncture combined with exercise therapy for nonspecific low back pain：a randomized controlled trial / 中国针灸

OBJECTIVE@#To compare the clinical effect between head acupuncture combined with exercise therapy and conventional acupuncture for nonspecific low back pain.@*METHODS@#A total of 64 patients with nonspecific low back pain were randomized into an observation group (32 cases, 2 cases dropped off) and a control group (32 cases, 2 cases dropped off). In the control group, conventional acupuncture was applied at Jiaji (EX-B 2) of L1 to L3, ashi point, Shenshu (BL 23), Dachangshu (BL 25), Yaoyangguan (GV 3) and Weizhong (BL 40). The observation group was treated with head acupuncture combined with exercise therapy, head acupuncture was applied at foot-motor-sensory area on the healthy side and Cuanzhu (BL 2), Tongziliao (GB 1) on the affected side, and McKenzie therapy was performed during retention. The needles were retained for 40 min, once a day, continuous treatment for 6 days with the interval of 1 day, 14 days were required in the two groups. Before and after treatment, the pain visual analogue scale (VAS) score, Oswestry disability index (ODI) score and infrared thermography temperature of pain area in the low back were compared in the two groups.@*RESULTS@#Compared before treatment, the VAS and ODI scores after treatment were decreased in the two groups (P<0.01), and those in the observation group were lower than the control group (P<0.01). Compared before treatment, the infrared thermography temperature of pain area in the low back after treatment was increased in the two groups (P<0.01), and that in the observation group was higher than the control group (P<0.01).@*CONCLUSION@#Head acupuncture combined with exercise therapy could relieve pain, improve dysfunction and increase the local temperature of pain area in patients with nonspecific low back pain, and its curative effect is better than conventional acupuncture.
