OBJECTIVETo observe the efficacy and safety of Qizhi Jiangtang Capsule (QJC) in treating stage 3b diabetic kidney disease (DKD) patients with macroalbuminuria.

METHODSPatients who conformed to the diagnostic criteria of stage 3b DKD were randomly assigned to two groups according to random digital table, the experiment group and the control group, 84 in each group. All patients received a two-week elution period, and then were treated with basic Western therapy. Patients in the experiment group took QJC, 5 pills per time, 3 times a day, while those in the control group took Valsartan Capsule 160 mg each time, once daily. The observation period of follow-ups was limited within 6 months, and the time points were set as the baseline, 1st month, 3rd month, and 6th month. Systolic blood pressure (SBP), diastolic blood pressure (DBS), 24 h urine protein quantitative (24 h UPQ), plasma albumin (ALB), and serum creatinine (SCr) were detected and recorded, and estimated glomerular filtration rate (eGFR) was calculated. The occurrence of hypoglycemic reaction, coagulation disorder, gastrointestinal tract reaction, allergy, hyperkalemia, doubling of creatinine, and overall adverse events were observed and recorded at same time.

RESULTSFinally 81 patients in the experiment group and 80 patients in the control group were effectively included. Compared with the baseline level, SBP and DBS obviously decreased in the control group at month 1 of treatment (P < 0.05), and more significantly decreased at month 6 of treatment (P < 0.01). SBP at month 1, 3, and 6 of follow-ups; DBS at month 6 of follow-ups was lower in the control group than in the experiment group (P < 0.05). At month 1, 3, and 6 of follow-ups, 24 h UPQ of the experiment group was significantly lower than the baseline level (P < 0.01). It was also significantly lower than the level of the control group at the same time point (P < 0.05). There was no significant difference in 24 h UPQ at month 1, 3, and 6 of follow-ups between the control group and the baseline level (P > 0.05). ALB of the experiment group showed an increasing trend. It was significantly higher than the baseline level at month 6 (P < 0.05), which was also higher than that of the control group at same period (P < 0.05). There was no significant difference in the ALB level in the control group (P > 0.05). SCr of two groups showed an increasing trend. SCr of the experiment group was significantly higher at month 1, 3, and 6 follow-ups than the baseline level (P < 0.05). But the increment of SCr was higher in the control group than in the experimental group, and obviously higher than the baseline levels (P < 0.05). eGFR of both groups showed a decreasing trend. The decrement was higher in the control group than in the experimental group (P < 0.05). The proportion of progression of renal functions at month 1, 3, and 6 of follow-ups in the experimental group was 0.0% (0 case), 9.55% (8 cases), and 21.4% (18 cases), while they were 8.3% (7 cases), 21.4% (18 cases), and 40.5% (34 cases) in the control group. There was no statistical difference in the proportion of progression of renal functions between the two groups at month 3 and 6 of follow-ups (P < 0.05). There was no statistical difference in the incidence of adverse reactions between two groups (P > 0.05).

CONCLUSIONQJC could effectively reduce urinary protein of patients with stage 3b DKD, and delay the progression of renal functions.

OBJECTIVETo explore the effects of high altitude on cognitive flexibility.

METHODSSimulated hypoxia at an altitude of 3 600 m was performed in a hypobaric chamber. Twenty-three volunteers without hypoxic experience were selected and the mean age was about 25.1 years. The physiological parameters (heart rate, blood pressure and oxygen saturation) were measured. Task switch paradigm was used to explore the cognitive flexibility in each phase, and the changing anxiety state was evaluated simultaneously.

RESULTSReaction time (RT) switch cost in hypoxia phase showed a significant increase compared with the baseline; anxiety level in hypoxia phase was higher than the adaptation phase; a remarkable negative correlation between anxiety level and RT switch cost was found in adaptation phase, whereas a positive correlation was found in landing phase.

CONCLUSIONHigh altitude (3 600 m) affects cognitive flexibility and anxiety state. Anxiety before the hypoxia exposure improves the cognitive flexibility performance, while anxiety after the hypoxia exposure hampers the performance because of the post-hypoxia effect.

Imatinib mesylate has been commonly used in the treatment of patients with chronic myeloid leukemia (CML). However, a significant number of CML patients treated with imatinib developed thrombocytopenia. Platelet-derived growth factor (PDGF)/platelet-derived growth factor receptor (PDGFR) plays a significant role in the regulation of thrombopoiesis. It is suggested that imatinib may block the PDGF/PDGFR and PI3-K/Akt pathway, then inducing the apoptosis of megakaryocytes and developing thrombocytopenia in these patients. In this review, the potential molecular mechanism of imatinib-induced thrombocytopenia in the treatment of CML patients is discussed, including imatinib and thrombocytopenia, PDGF/PDGFR and thrombopoiesis, potential mechanism of imatinib-induced thrombocytopenia in treatment of patients with CML and so on.

OBJECTIVETo explore the role of hypoxia in skeletal myoblasts proliferation and related mechanism.

METHODSThe numbers and proliferous indexes of skeletal myoblasts were detected by flow cytometer under 20%, 3%, and 10% oxygen concentration. Hypoxia inducing factor 1alpha (HIF-1alpha) mRNA expression was determined by reverse transcriptase-polymerase chain reaction (RT-PCR). HIF-1alpha proteinum in endochylema and intranucelus were respectively detected by Western blot.

RESULTSThe numbers and proliferous indexes were higher (P < 0.05) in hypoxia group than those of control group. The expression HIF-1alpha mRNA had no difference in hypoxia and in normal groups. The level of HIF-1alpha proteinum in endochylema under normoxia was more than that in intranucelus and it was opposite under hypoxia.

CONCLUSIONHypoxia can promote the proliferation of skeletal myoblasts. The possible mechanism of hypoxia promoting the proliferation of skeletal myoblasts might be that low oxygen concentration regulates HIF-la nuclear translocation.

OBJECTIVETo investigate the effects of benzene poisoning on the expression of multidrug resistance 1 (MDR1) gene and P-glycoprotein (P-gp) in the bone marrow mononuclear cells (BMMNCs) of C57BL/6 mice.

METHODSC57BL/6 mice were randomly divided into control group (n = 24), low-dose group (n = 24), medium-dose group (n = 24), and high-dose group (n = 24) to receive corn oil, 25 mg/kg benzene, 50 mg/kg benzene, or 100 mg/kg benzene by gavage, once daily, 5 days/weeks, for 4 weeks. The mice were sacrificed on day 12, 26, or 29 of poisoning. Peripheral blood routine test was performed; real-time quantitative PCR was used to measure the MDR1 gene expression in BMMNCs; Western blot was used to measure the P-gp expression in BMMNCs.

RESULTSOn day 12, the red blood cell count and hemoglobin level in the high-dose group were significantly lower than those in the control group, low-dose group, and medium-dose group (P < 0.01 or P < 0.05). On day 26, the white blood cell count in the high-dose group was significantly lower than those in the control group, low-dose group, and medium-dose group (P < 0.01 or P < 0.05). At each time point, the mRNA expression of MDR1 gene in the low-dose group, medium-dose group, and high-dose group was significantly lower than that in the control group (P < 0.01). On day 26, the P-gp expression in the high-dose group was significantly lower than those in the control group, low-dose group, and medium-dose group, and the P-gp expression in the medium-dose group was significantly lower than that in the low-dose group (P < 0.01 or P < 0.05). On day 29, the P-gp expression in the low-dose group, medium-dose group, and high-dose group was significantly lower than that in the control group (P < 0.05).

CONCLUSIONBenzene poisoning can affect the expression of MDR1 gene and P-gp, which may be one of the mechanisms of benzene hematotoxicity.
