Objective To observe the effects of Yiqi Yangyin Recipe (supplementing qi and nourishing yin) and its different assembling on apoptosis rate and associated protein expression of c-myc and survivin in mice, and explore its mechanism. Methods NOD-SCID mice were injected with l×106 KG1a cells from the tail vein after irradiation of 60Co. Model mice were randomly divided into control group, whole recipe group, strengthening body resistance group, eliminating pathogens group. The treatment groups were given correspongding administration, and control group was given equal volume of NS. Flow cytometry was applied to measure apoptosis rate. The immunochemistry method was used to detect the expression of c-myc, survivin. Results Apoptosis rate in all treatment groups were increased (P<0.01). The expression of c-myc and survivin in lymph node tissues in all treatment groups were significantly declined compared with control group (P<0.05). The effect of whole recipe group on the all indices was superior to strengthening body resistance group and eliminating pathogens group (P<0.05). Conclusion Yiqi Yangyin Recipe can decrease the expressions of c-myc and survivin, induce apoptosis in leukemia cells, therefore shows the therapeutic effect.

Objective To investigate the incidence,characteristics and risk factors of cognitive impairment in patients with transient ischemic attack(TI A) or minor stroke.Methods Montreal cognitive assessment(MoCA) was carried out in 279 patients with TIA or minor stroke and 150 healthy controls to assess their cognitive function.Results (1) Compared with the healthy controls,the TIA/minor stroke patients scored significantly lower on MoCA total score((23.98±2.55) vs (26.60±0.99),t=12.084,P＜0.01) and subtests including visuoexecutive function((3.68±0.94) vs (4.41±0.64),t=8.483,P＜0.01),digital span ((1.81±0.40) vs (1.95±0.23),t=3.771,P＜0.01),attention((0.84±0.37) vs (0.95±0.23),t=3.357,P＜ 0.01),repetition((1.59±0.62) vs (1.89±0.37),t=5.496,P＜0.01),verbal fluency((0.88±0.33) vs (0.95 ± ±0.23),t=2.286,P＜0.05),abstraction((1.55±0.64) vs (1.91±0.34),t=6.357,P＜0.01) and recall ((2.87±1.13) vs (3.18±0.41),t=3.281,P＜0.01) were significantly decreased.(2) Of 279 TIA/Minor stroke patients,213 (76.3％) suffered from cognitive impairment.The incidence of cognitive impairment was positively correlated with the gender,age,educational level,smoking,course,leukoaraiosis,comorbidities such as hypertension,diabetes mellitus(P＜0.05),and negatively correlated with hyperlipidemia(P＞0.05).Conclusion Extensive impairments of cognitive functions occur along with the incidence of TIA or minor stroke.It is thus suggested that cognitive assessment and interventions may be carried out at an early stage.

Objective Gas chromatography-mass spectrometer (GC-MS) technology combined with Heuristic evolving latent projections (HELP) method were used to qualitatively analyze the volatile oil of fructus lycii (Lycium barbarumL.)Methods With the best temperature-programmed chromatographic condition, overlapping peaks among the total ion chromatogram were separated. Then an automatic mass spectral deconvolution and identification system (AMDIS) was used to identify volatile components comprehensively. Finally, the pure chromatographic peaks were matched with NIST 05a mass spectra library for giving the precise qualitative result. Results Totally, 29 compounds in fructus lycii (Lycium barbarum L.) were identified accurately.Conclusions Compared with the traditional qualitative analysis method, the new established method which GC-MS technology combined with HELP could get tremendous advantages. It not merely enhanced the accuracy of identification but also solved the bottleneck of handling the inseverable compounds.

Objective To explore the condition of cortistatin (CST)expression in human renal tissue and the changes in the level of CST in IgA nephropathy (IgAN)of different degrees.Methods Ten tumor adjacent normal renal tissue samples were collected.The mRNA and protein expressions of CST in human renal tissue were detected by reverse transcription-polymerase chain reaction (RT-PCR)and Western blotting,respectively.Immunohistochemisty (IHC)was performed to locate the expression of CST in renal tissue.According to the grading system of Lee et al,IgAN was divided into three groups:grade Ⅰ -Ⅱ (group A),grade Ⅲ -Ⅳ (group B),and grade Ⅴ (group C),and ten renal biopsy tissue samples were collected for each group.IHC was performed to detect the change in the level of CST in normal and IgAN renal tissue of different degrees.The effect of clinical indices on the level of CST in IgAN renal tissue was assessed by multiple linear regression analysis.Results RT-PCR and Western blotting showed that CST was expressed in renal tissue and IHC showed that CST was expressed on renal tubular epithelial cells.In IgAN,the higher the pathological grade was, the higher the expression of CST in renal tubules was.Multiple linear regression analysis showed that the pathological grade was associated with the expression of CST in renal tissue (r =0.875,P <0.01).Conclusion CST may participate in the inflammatory reaction of IgAN pathological injury and exert anti-inflammation effects.

Objective:To analyze the clinical characteristics of primary acute myeloid leukemia (AML) (non-M3 type) in children suffering from different levels of platelet count(PLT).Methods:In the Tumor Hospital of Zhengzhou University from January 2014 to December 2018, laboratory and clinical data of 247 de novo primary AML pediatric patients were retrospectively reviewed.According to the PLT before treatment, patients were divided into very low platelet group (VLG), low platelet group (LG) and non-lowing platelet group (NLG), with<50×10 9/L, ≥50×10 9/L but <125×10 9/L and ≥125×10 9/L as the boundaries.All patients were followed up until June 30, 2019.Meanwhile, the follow-up data was obtained by consulting medical records or by telephone.SPSS 17.0 software was applied for data analysis. Results:In general clinical features, a different group of hemoglobin (Hb) content, fusion gene AML- ETO and clinical risk stratification were statistically significant in different PLT groups ( χ2=11.270, 12.115 and 12.848, respectively, all P<0.05). However, the differences of other indicators in different groups of PLT were not statistically significant (all P>0.05). There were no statistically significant differences in terms of 3-year disease-free survival(DFS) rate (59.3%, 36.3%, 50.4%) among the 3 groups (all P>0.05). The median total survival(OS)time(40.5 months)and 3-year OS rate(41.0%) of NLG patients were significantly higher than those of VLG(23.1 months, 30.1%)and LG(14.1 months, 18.2%)patients, with statistically significant differences( χ2=7.798 and 6.553, respectively, all P<0.05). The univariate analysis of gender, white blood cell(WBC), Hb, PLT, lactic dehydrogenase(LDH), FLT3-ITD, NPM1, DNMT3A, CEPBA, C-KIT, AML-ETO, molecular genetic prognosis, complete remission(CR), and hemopoietic stem cell transplantation(HSCT) displayed that DNMT3A mutation was an adverse factor that affects patients′ OS ( χ2 =5.834, P<0.05), and the positive factors that influences OS were non-reducing PLT before treatment, and obtaining CR and subsequent HSCT ( χ2=7.798, 79.168, and 31.337, respectively, all P<0.05). Multi-factor analysis revealed that the independent protective factors that affect patients′ OS were the non-reducing PLT before treatment, and obtaining CR and subsequent HSCT( Wald=42.760, 15.918, and 10.183, respectively, all P<0.05). Conclusions:Before treatment, non-reducing PLT is a protective factor for primary childhood AML patients, and the prognosis is satisfying.

Objective To study the mechanism of the protective effect of lycium barbarum polysaccharide on light aging resistance rats by using the metabolic profile and metabolic target analysis technique.Methods Ultraviolet irradiation induced Wistar rats were induced to produce skin photo aging model and 24 rats were randomly divided into three groups, including control goup, model group, Lycium barbarum polysaccharide group (LBP). After modeling for 24 hours, LBP group was conducted with Lycium barbarum polysaccharide solution of 10 mg/kg. Control group and model group were given same volume of stroke-physiological saline solution for 14 days. The biochemical indexes such as rat serum antioxidant activity of related substances and MDA were measured in model group and drug group; the urine metabolomics study was also investigated for the mechanism of lycium barbarum polysaccharide against light aging band.Results Compared with the model group, the LBP group rats total superoxide dismutase activity (301.51 ± 42.56 U/mgvs.93.41 ± 56.31 U/mg), hydroxyproline (8.91 ± 5.78μg/mgvs.4.74 ± 1.54μg/mg) content significantly increased (P<0.05), but the malondialdehyde (8.54 ± 6.41 nmol/mgvs.21.31 ± 6.58 nmol/mg) decreased without any statistics difference (P<0.05). The urine metabonomics results showed that LBP could regulate the skin photoaging of multiple metabolic pathways and key metabolic enzymes in the process, such as peanut four acid, tyrosine, taurine, citric acid and hippuric acid, L-cysteine, inositol, threonine etc.Conclusions In the process of skin photoaging in rats, multiple metabolic pathways in vivo were disordered, and Lycium barbarum polysaccharide could play a protective role by regulating the key metabolic enzymes in the network.
