This study was aimed to investigate the preventing efficacy of the combined using of Er-Shi-Wu-Wei Shan-Hu (ESWWSH) pill, Ru-Yi Zhen-Bao (RYZB) pill, Er-Shi-Wei Chen-Xiang (ESWCX) pill on the focal cere-bral ischemia injury in rats. A total of 80 Sprague-Dawley (SD) rats were randomly divided into four groups. In the sham operation group and the MCAO model group, normal saline was given orally every day (1 mL/100 g). In the positive control group, nimodipine was given orally every day (1.89 mg/100 g). In the drug combination group, ESWWSH pill (7 mg/100 g), RYZB pill (31.5 mg/100 g), ESWCX pill (49 mg/100 g), were separately given in the morning, noon and evening every day. Improved MCAO was used in the model establishment after 7-day intragastri-cal administration. After 24 h brain infarction, TTC method was used in the determination of the cerebral infarct size. Drying and weighing method was used in the calculation of brain water content. Determinations were made on con-tent of NO in ischemic brain issues (nitrate reductase method); activities of SOD in serum (xanthine oxidase method);content of MDA in serum (TBA method); and activities of LDH in serum (pyruvate method). The results showed that compared with the MCAO model group, the combined using of three Tibetan classical prescriptions can obviously re-duce the cerebral infarct size, brain water content and the NO content in brain issues, increase the activity of SOD, reduce the content of MDA, and reduce the activity of LDH in serum. It was concluded that the research preliminari-ly showed that the combined using of ESWWSH pill, RYZB pill and ESWCX pill can protect the ischemic brain tis-sues, such as reducing the cerebral infarct size, alleviating brain edema, and inhibiting oxidative stress reactions.

Results The thumb oppositional function of all the ten patients recovered. The myodynamia reached level 4 and the shape of thenar was satisfying after 6 to 12 months of follow-up visit. Conclusions Sufficient preoperative psychological nursing and effective postoperative rehabilitative treatment had pivotal significance for the success of operation and the recovery of thumb oppositional function.

The identification of pathogenic antigens in membranous nephropathy (MN) is a hot topic in the research field of kidney diseases. In recent years, the widespread application of mass spectrometry has brought a breakthrough in the identification of MN-pathogenic antigens. As the antigen spectrum continues to be refined, the diagnosis of MN has evolved from morphological level to molecular level. This article reviewed the research progress of currently identified antigens of MN, such as phospholipase A2 receptor (a major pathogenic antigen of primary MN), thrombospondin type 1 domain-containing 7A (a potential tumor-associated antigen), neural epidermal growth factor-like protein 1 (an antigen associated with various secondary factors), semaphorin 3B (an antigen specific to pediatric MN) and so on, and the pathogenic mechanisms and clinical significance of these antigens.

Objective To report the spontaneous remission and induced remission of phospholipase A2 receptor (PLA2R)-associated idiopathic membranous nephropathy (IMN) in adults,as well as to explore the potential prognostic factors.Methods A total of 120 patients with IMN in Huashan Hospital during 2012 and 2017 were enrolled and their clinical data were collected.Results PLA2R-associated IMN patients accounted for 89.2％ of the IMN patients.Spontaneous remission occurred in 35.5％ of PLA2R-associated IMN patients.The patients with higher serum albumin and lower level of PLA2R antibody were more likely to achieve spontaneous remission (both P ＜ 0.05).Multivariate logistic regression analysis showed that male was an independent risk factor for spontaneous remission in PLA2R-associated IMN patients (OR=0.060,95％CI 0.007-0.493,P=0.009),while higher serum albumin at baseline (OR=1.480,95％ CI 1.144-1.932,P=0.004) and the improvement of serum albumin after 3 months' non-immunosuppressive treatment (OR=2.040,95％CI 1.322-3.151,P=0.001) were independent protective factors for spontaneous remission.About 42.1％ PLA2R-associated IMN patients had received immunosuppressive therapy,with induced remission rate being 70.7％.High serum albumin before treatment was an independent protective factor for induced remission (OR=1.268,95％ CI 1.014-1.585,P=0.038).Conclusions PLA2R-associated IMN accounts for most of the IMN patients,with a spontaneous remission rate of 35.5％,during the follow-up period,which is even higher in patients with higher baseline serum albumin and lower PLA2R antibody titer.Induced remission rate is 70.7％ in patients in need of immunosuppresants.The serum albumin level may be helpful in predicting spontaneous remission and response to immunosuppressive therapy.

Objective:To investigate the prognostic significance of different IDH mutations and accompanying gene mutations in patients with non-M 3 acute myeloid leukemia (AML) . Methods:Second-generation sequencing was performed to detect the mutations of 22 genes in 389 patients with AML in the First Affiliated Hospital of Zhengzhou University from June 2016 to December 2018, and Kaplan-Meier and Cox regression models were used to analyze the prognostic factors.Results:The mutation frequency of IDH1 and IDH2 was 6.2% and 8.7% , respectively, in all patients without co-mutation. The IDH2 mutant group had an older age, higher proportion of bone marrow primitive cells, more common normal karyotype, and more common RUNX1 and SRSF2 mutations compared with IDH2 wild-type group. Univariate analysis of variance showed that the median OS and PFS of IDH1 mutation group were significantly shorter than those of the wild-type group ( P<0.05) . IDH2 mutation as a single variable and IDH2R140 mutation had no significant effect on the prognosis, while different mutation sites had different effects. Compared with the IDH2 wild-type group, the IDH2R172 mutation group had lower complete remission (CR) rate and shorter median OS and PFS ( P<0.05) . In patients with normal karyotypes or aged ≥50 years, IDH2 mutation as a single variable had no significant effect on the prognosis, IDH1 mutation and IDH2R172 mutation were associated with poor OS and PFS ( P<0.05) , and IDH2R140 mutation had no significant effect on OS and PFS. Approximately 74.1% (43/58) of patients with IDH mutation simultaneously carried other gene mutations; however, the number of accompanying gene mutations had no significant effect on the prognosis. Among 58 patients with IDH mutation, the CR rate of patients with NPM1 mutation was significantly higher than that of patients in the NPM1 wild-type group (81.8% vs 36.4% , P=0.014) , the median OS in patients with DNMT3A mutation was lower than that of patients with DNMT3A wild type [4.0 months (95% CI 3.8-4.2) vs 6.3 months (95% CI 2.4-10.2) , P=0.041) ]. Multivariate analysis showed that age ≥60 years and white blood cell count ≥100×10 9/L were independent risk factors for OS and PFS, while CR after two courses of treatment and hematopoietic stem cell transplantation were independent prognostic favorable factors for OS and PFS. Conclusion:In patients with AML (non-M 3) , IDH gene mutations often coexisted with other gene mutations, and different subtypes and accompanying gene mutations of IDH have different prognostic significance.

To evaluate the relationship between atherosclerosis and hemodynamic of coronary artery in mice detecting by ultrasound bio‐microscopy flow imaging . Methods Double 14 20‐week‐old LDL‐R‐/‐and C57BL/6 male mice were selected ,and randomly divided into two groups in each genotype according to weight . Each two groups were fed to 28 weeks or 36 weeks age respectively with west diet . Coronary artery hemodynamics in these mice were assessed in vivo by Vevo ?2100 ultrasound imaging system ,then the intima‐media thickness( IM T ) of aorta in histopathology were analyzed . T he differences of coronary artery hemodynamic parameters such as maximum velocity ( Vmax ) ,mean velocity ( Vmean) and velocity time integral ( V T I) were compared between mice of different genotypes of the same week and mice of different weeks of the same genotype . And the relationship between coronary artery hemodynamic in ultrasound and aortic IM T in histopathology were analyzed . Results ① All coronary hemodynamic parameters in LDL‐R‐/‐ mice were significantly lower than those of wild‐type mice except the Vmax between two 28‐week‐old genotypes group at the same weeks of age of different genotypes ( all P ＜0 .05) . But there was no significant difference in coronary artery hemodynamic parameters between mice of the same genotype at different weeks of age( P ＞0 .05) . ②T he histopathological measurements of aortic IM T in LDL‐R‐/‐mice were significantly higher than those of wild type mice ( all P ＜ 0 .05 ) ,and those of 36‐week‐old mice were significantly higher than those of 28‐week‐old mice ( all P ＜ 0 .05 ) . ③ All coronary hemodynamic parameters such as Vmax ,Vmean and V TI were negatively correlated with pathological measurements of aortic IM T ( r ＝ －0 .532 , －0 .423 , －0 .524 ; all P ＜ 0 .05 ) . Conclusions The parameters of coronary artery hemodynamics obtained by ultrasound bio‐microscopy are well correlated with the pathological results of atherosclerosis . Ultrasound bio‐microscopic flow imaging can be used as a new method to evaluate the degree of atherosclerosis in mice by detecting the hemodynamic parameters of coronary artery .
