Mantle cell lymphoma (MCL), is a disease with high heterogeneity, which is insensitivity to the chemotherapy and presents poor prognosis. Appearance of the Bruton tyrosine kinase (BTK) targeted inhibitors, such as ibrutinib, provides novel treatment strategy for MCL. This review focused on the latest achievements of BTK inhibitors in MCL treatment.

Branch atheromatous disease (BAD) is a deep cerebral infarction at the entrance or the origin of perforating artery because of atherosclerosis causing lumen stenosis or occlusion. It is common in clinical practice and there is often a clinical feature of progression or fluctuation in the acute phase. Its prognosis is poor and it will bring a heavy burden to the family and society. Therefore, the early intervention for patients with BAD is very important. This article reviews the treatment of BAD.

Sixty cases of chronic pulmonary heart disease at acute attack stage in the treatment group and 60 cases of the control group were treated with oxygen-inspiration, relieving spasm and asthma,anti-infection, and correcting respiratory failure and heart failure as basic treatment. Self-made Chinese drug Fei Xin Ning Mixture was added to the treatment group. In the two groups,15 days constituted one course.Plasma endothelin-1(ET-1) level and hemorheologic indices were determined before and after treatment. Results indicated that the markedly effective rate,effectice rate and the total effective rate in the treatment group were 73.33%,20% and 93.34% respectively,and 35%,33.34% and 68.34% in the control group,with significant difference in the total effective rate between the two groups(P<0.01).Plasma endothelin-1 level after treatment in the treatment group was significantly lower than that in the control group(P<0.01),and the hemorheologic indices in the treatment group decreased significantly as compared with those before treatment or after treatment in the control group(P<0.05 or P<0.01).It is suggested that Fei Xin Ning Mixture can obviously increase the total effective rate and decrease plasma endothelin-1 level and improve blood rheology for chronic pulmonary heart disease at acute attack stage,and it has a better therapeutic effect than that of the simple Western medicine treatment.

AIM: To investigate the effect of selective silencing of SLC7a8 on uptaking L-dopa in renal tubular epithelial cells of rat (NRK-52E). METHODS: The three siRNAs targeting SLC7a8 (siRNA-1, siRNA-2, siRNA-3) were designed and synthesized. A siRNA with nonspecific coding sequence (siRNA-con) was used for control. All siRNAs were transfected into NRK-52E cells. The siRNA-con transfected group, blank control group and gene-specific silencing SLC7a8 group were set up. The efficiency of transfection was estimated by flow cytometry. The efficiency of RNA interference was detected and screened by RT-PCR preliminarily, and was followed by Western blotting at protein level. The concentrations of L-dopa uptake into the NRK-52E cells were detected by ultraviolet spectrophotometry at different time points (6, 12, 24, 36, 48, 60, 72 and 120 min). RESULTS: The transfection efficiency was 94% detected by flow cytometry. The initial screening of RT-PCR showed that the efficiencies of RNA interference of siRNA-1 and siRNA-3 were higher, and siRNA-3 was the highest at protein level determined by Western blotting. No distinctive change was found between siRNA-con treated NRK-52E and blank control cells. The L-dopa uptake at different time points (6, 12, 24, 36, 48, 60, 72 and 120min) in siRNA-interference group was lower than that in siRNA-con transfected group and blank control group. No significant difference of L-dopa uptake between siRNA-con group and blank control group was observed. CONCLUSION: RNA interference technology selectively down-regulates SLC7a8 expression in rat renal tubular epithelial cells. The L-dopa uptake is also decreased after specifically silencing the slc7a8 expression.

OBJECTIVETo study the protective effects of astragaloside (AST) on memory impairment and the expression levels of amyloid precursor protein (APP) and its mRNA, alpha secretase and beta secretase mRNA in the brain of mice induced by dexamethasone (DEX).

METHODMice were randomly divided into six groups: control group, model group, AST ( 10, 20, 40 mg x kg(-1)) groups and ginsenoside Rg1 (6.5 mg x kg(-1)) group. The animal models of dysmnesy mice were established by intragastrical administration of DEX (5 mg x kg(-1)) for 21 days. Subsequently, the dysmnesy mice were treated by intragastrical administration of ginsenoside Rg1 and different doses of AST (10, 20, 40 mg x kg(-1)), respectively. Morris water maze was applied to evaluate the learning and memory function in mice. The expression of APP, alpha secretase and beta secretase mRNA were analysed by RT-PCR, and immunohistochemistry was used to evaluate the expression levels of APP in cerebral cortex, hippocampus CA1 and CA3.

RESULTAST (20, 40 mg x kg(-1)) could improve the learning and memory function in mice (P<0.05, P<0.01), decrease the expression levels of APP and beta secretase mRNA (P<0.05), increase the expression level of alpha secretase mRNA (P<0.05), and decrease the expression level of APP in cerebral cortex and hippocampus CA1 (P<0.05).

CONCLUSIONAST could improve the learning and memory function in mice, which mechanism may contribtuted to the expression inhibition of APP and APP mRNA, beta secretase mRNA, and promotion of the expression of alpha secretase mRNA.

Objective The aims of this study were to analyze the clinical characteristics and laboratory test results of stageⅣ lung cancer patients with Pulmonary thromboembolism(PTE),and to find out the risk factors for pulmonary thromboembolism. Methods A total of 70 patients with stage IV lung cancer were selected from the First Affiliated Hospital of Nan Chang University from January 2011 to October 2017. Blood routine,blood biochemistry,coagulation function,tumor markers(CEA,CA199,CA125, NSE,Cyfra211)and multi-slice spiral CT pulmonary angiography(CTPA)were collected in these patients. Univariate analysis was applied to compare the clinical features and laboratory tests between PTE and non-PTE groups. Multivariate logistic regression analy-sis was applied to explore significant risk factors of PTE. Results Univariate analysis showed that serum albumin,blood leukocyte, neutrophil percentage,increased Cyfra211 and abnormal tumor markers were risk factors for PTE in patients with stage IV lung canc-er. Multivariate logistic regression analysis showed that the number of abnormal tumor markers ≥4(OR=7. 016,95% CI:1. 916 ~25. 686)was an independent risk factor for PTE in stage IV lung cancer. Conclusion The number of abnormal tumor markers is an independent risk factor for pulmonary thromboembolism in stageⅣlung cancer. When the number of abnormal tumor markers is≥4, it is necessary to highly alert the possibility of stage IV lung cancer with pulmonary thromboembolism.

Objective:The results of syphilis antibody screening in Peking University Third Hospital from 2016 to 2020 were analyzed,to explore the characteristics of sex, age and distribution of patients with positive syphilis antibody.Methods:A retrospective study was conducted to collect the results of syphilis antibody in outpatients and inpatients of Peking University Third Hospital from 2016 to 2020. Syphilis antibodies were screened in 626 528 patients aged 1-98 years, 4 232 were retested positive by TPPA test, including 2 132 males (50.4%) and 2 100 females (49.6%). Chemiluminescence immunoassay (CMIA) was used for syphilis antibody screening, and Treponema pallidum particle agglutination (TPPA) test was used for reexamination. SPSS20.0 data statistical analysis software was used to analyze the detection rate, age, sex, department and clinical diagnosis of patients with positive syphilis antibody by χ2 test.Results:Among 626 528 patients who were positive for treponema pallidum antibody screening, 4 232 were retested positive by TPPA test, accounting for 0.68% of the total number of patients tested. The number of syphilis tests increased year by year, however the positive detection rate decreased. The positive detection rate of syphilis antibody in 2020 decreased by 18.9% compared with 2016. The positive rate of syphilis antibody in male patients was higher than that in female patients, accounting for 0.80% and 0.59% of the total number of patients tested respectively. The positive rate of syphilis antibody of different genders increased with age, the total positive rate of 0-20, 21-40, 41-60, 61-80,>80 years old were 0.15%, 0.45%, 0.95%, 1.07% and 1.41%, respectively. While the increase rate of males was higher than that of females. The positive rate of male over 80 years old was 18.13 times of the group of 0-20 years old, and 5.54 times in women. The top 6 departments with positive syphilis antibody detection rate were emergency department, oncology department, respiratory department, geriatrics department, endocrinology department and neurology department, and the positive rates were 1.79% (104/5 810),1.46% (55/3 767),1.20% (74/6 167),1.20% (22/1 833),1.10% (32/2 909),1.09% (94/8 624), respectively. From the analysis of clinical diagnosis, the proportion of positive syphilis antibody in infertile patients (0.64%, 672/104 911) was higher than that in naturally conceived patients (0.10%, 24/23 969).Conclusions:From 2016 to 2020, the positive detection rate of syphilis antibody in Peking University Third Hospital decreased year by year. However, the positive detection rate increased with the age of patients. The positive rate of syphilis antibody in male was higher than that in female. The positive rate of syphilis antibody in pregnant women was lower than that in infertile patients.

Six patients with factor Ⅴ deficiency were admitted in Shandong Provincial Hospital Affiliated to Shandong First Medical University from January 2006 to December 2022. All 6 patients presented with symptoms of coagulation dysfunction, 4 patients had recurrent nose bleeding, gingival bleeding, skin ecchymosis as the main manifestations, 1 patient had lower abdominal pain and ovarian active bleeding, and 1 patient had heavy menstruation. The prothrombin time and activated partial thromboplastin time were significantly prolonged, the factor Ⅴ level was significantly lower than normal, and the thrombin time was basically normal in all patients. Four patients received non-surgical treatment and transfusion of fresh frozen plasma; the bleeding symptoms were significantly relieved during hospitalization, and no aggravation of bleeding symptoms was found during follow-up. One patient with active ovarian hemorrhage underwent emergency surgical suture to stop bleeding, and fresh frozen plasma and prothrombin complex were given perioperatively; and no more bleeding occurred during follow-up. One patients with excessive menstruation underwent curettage plus hysteroscopic endometrial ablation, and the amount of menstruation was significantly reduced. It is suggested that the bleeding symptoms of coagulation factor Ⅴ deficiency vary in severity, which can be effectively alleviated by infusion of the fresh frozen plasma in most cases.
