ABSTRACT
Objective:To explore the impact of treatment duration with human urinary kallidinogenase (HUK) on the efficacy and safety of acute ischemic stroke (AIS).Methods:In this subgroup analysis of RESK study, a total of 990 AIS patients recruited from 65 centers in China between August 2015 and June 2020 were included and divided into short medication group (HUK for 8 days, n=185) or long medication group (HUK for 15 days or 21 days, n=805). The proportions of patients with modified Rankin Scale (mRS) score of 0, 0-1, 0-2 at 90 days, National Institutes of Health Stroke Scale (NIHSS) score change from baseline to 22 days, the proportions of patients with Barthel index (BI)≥95 at 90 days, and the incidences of adverse events were analyzed. Comparisons between groups were conducted using chi-square test, single factor and multivariate Logistic regression analysis, etc. Results:Multivariate regression analysis showed that the proportions of patients with 90-day mRS score of 0-2 [74.1% (137/185) vs 75.0% (604/805); OR=1.047, 95% CI 0.676-1.620, P=0.838] and 22-day NIHSS score change from baseline (4.60±2.00 vs 4.26±2.80; OR=-0.390, 95% CI -1.125-0.344, P=0.297) showed no statistically significant difference between the short medication and long medication groups; the proportions of patients with 90-day mRS score of 0-1 [48.1% (89/185) vs 59.1% (476/805); OR=0.674, 95%CI 0.463-0.983, P=0.041] and 90-day BI≥95 [43.6% (79/181) vs 55.1% (442/802); OR=0.614, 95%CI 0.420-0.897, P=0.012] were significantly lower in the short medication group than in the long medication group. There was no statistically significant difference in the incidences of adverse events between these 2 groups. Conclusions:In AIS patients, consecutive 8-day dosing of HUK improved immediate (22-day NIHSS score) and long-term outcome (90-day mRS score 0-2) and was safely tolerated. When applicable, extended duration of HUK could improve long-term disability-free rate (90-day mRS score 0-1) and quality of life (90-day BI) without increasing the risk of adverse events.
ABSTRACT
Objective To explore the effects of Cordyceps sinensis extract (CSE) on osteoporosis and RANKL-mediated osteoclastogenesis. Methods Bone marrow-derived macrophages (BMMs) was isolated from the bone marrow of C57BL/6 mice. CSE was added in osteoclast differentiation. Osteoclasts were stained by tartrate-resistant acid phosphatase (TRAP). The nearly mature osteoclasts were planted on hydroxyapatite plates and the area of bone lacunae was observed by microscope. The F-actin belt was stained by DAPI and phylloeptide and the number of nuclei was observed by confocal microscopy. The expressions of DC-STAMP, ATP6V0D2, TRAP, CTSK, and NFATC1 were detected by q-PCR. The protein expression of the MAPK pathway was detected by Western Blot. The in vivo experiments were carried out by administering CSE to the ovariectomized mice daily through gavage. After 6 weeks of intervention, mouse femurs were taken for morphological analysis. Peripheral blood was taken for ELISA. Results CSE represses osteoclastogenesis, bone resorption, F-actin belts formation, osteoclast specific gene expressions and MAPK signaling pathways in vitro. In vivo study indicated that CSE prevents OVX-induced osteoporosis and preserves bone volume by repressing osteoclast activity and function. It also increases the serum ALP, BGP content, and reduces TRAP content. Conclusion CSE can attenuate osteoclast formation and OVX-induced osteoporosis, suggesting potential clinical therapeutic effects for osteoporosis.
ABSTRACT
Objective:To investigate the expressions of nuclear factor of activated T cell 5 (NFAT5) in lung adenocarcinoma tissues and cells, and the effects of NFAT5 on the proliferation, invasion, migration and apoptosis of lung adenocarcinoma cells.Methods:The clinical pathological specimens and paracancerous tissues of 61 patients with lung adenocarcinoma diagnosed and treated in 904th Hospital of Joint Logistic Support Force of People′s Liberation Army from June 2017 to June 2019 were collected. The expression levels of NFAT5 in lung adenocarcinoma tissues and paracancerous tissues were detected by quantitative real-time PCR (qRT-PCR), and the relationships between the expression of NFAT5 and clinicopathological features of patients were analyzed. H1975 cells were divided into control group (no treatment), NC group (transfecting siRNA-NC) and si-NFAT5 group (transfecting siRNA-NFAT5) . qRT-PCR was used to detect the expression level of NFAT5 in cell line. MTT and clone formation assay were used to detect cell proliferation. Transwell and scratch test were used to detect cell invasion and migration ability. Flow cytometry was used to detect cell apoptosis. The expressions of mitogen-activated protein kinase (MAPK) signaling pathway related proteins were detected by Western blotting.Results:The expression level of NFAT5 mRNA in lung adenocarcinoma (3.22±0.20) was significantly higher than that in paracancerous tissues (1.00±0.12), and there was a statistically significant difference ( t=75.662, P<0.001). The expression level of NFAT5 in lung adenocarcinoma tissue was associated with TNM stage ( χ2=10.357, P=0.001) and lymph node metastasis ( χ2=18.268, P<0.001). The expression levels of NFAT5 in the control group, NC group and si-NFAT5 group were 1.00±0.06, 1.01±0.05 and 0.31±0.06, and there was a statistically significant difference ( F=140.498, P<0.001). The absorbance ( A) values in the control group, NC group and si-NFAT5 group were 0.70±0.01, 0.55±0.01 and 0.35±0.01 at 24 h after transfection, 0.92±0.03, 0.87±0.06 and 0.57±0.06 at 48 h after transfection, 1.05±0.01, 0.90±0.01 and 0.66±0.01 at 72 h after transfection, and there were statistically significant differences ( F=9.815, P=0.013; F=45.977, P<0.001; F=129.494, P<0.001). Further pairwise comparison showed that the proliferation abilities of the si-NFAT5 group at 24, 48 and 72 h were significantly lower than those of the control group and NC group (all P<0.001). The cell clone numbers in the three groups were 452.33±31.50, 421.00±17.35 and 129.00±17.35 respectively, with a statistically significant difference ( F=128.200, P<0.001). The cell clone number in the si-NFAT5 group was significantly lower than that in the control group and NC group (both P<0.001). The invasion numbers of cells in the three groups were 262.67±28.02, 278.00±27.50 and 46.00±12.00 respectively, and there was a statistically significant difference ( F=89.896, P<0.001). The cell invasive ability in the si-NFAT5 group was significantly lower than that in the control group and NC group (both P<0.001). The relative scratch widths in the three groups were 0.28±0.04, 0.32±0.04 and 0.54±0.04 respectively, and there was a statistically significant difference ( F=42.889, P<0.001). The relative scratch width in the si-NFAT5 group was significantly increased than that in the control group and NC group (both P<0.001). The apoptosis rates in the three groups were (3.38±0.56)%, (3.14±0.62)% and (13.82±0.75)% respectively, and there was a statistically significant difference ( F=264.705, P<0.001). The apoptosis rate in the si-NFAT5 group was significantly higher than that in the control group and NC group (both P<0.001). The differences of protein expressions of NFAT5, p-P38/P38, p-ERK1/2/ERK1/2, p-JNK/JNK among the three groups were statistically significant ( F=91.245, P<0.001; F=132.896, P<0.001; F=243.332, P<0.001; F=118.358, P<0.001). The protein expressions of NFAT5, p-P38/P38, p-ERK1/2/ERK1/2, p-JNK/JNK in the si-NFAT5 group were all significantly lower than those in the control group and NC group, and there were statistically significant differences (all P<0.001). Conclusion:The expression of NFAT5 is increased in lung adenocarcinoma tissues and cells. Inhibition of NFAT5 can inhibit proliferation, invasion and migration of lung adenocarcinoma H1975 cells, and promote apoptosis of H1975 cells. The mechanism may be related to the inhibition of MAPK signal pathway by NFAT5.

ABSTRACT
ObjectiveTo investigated the effects of Rhodiola Compound on improving the intellective function in mice and provide the basis for clinical application.MethodsMice were divided to different groups of three doses of rhodiola compound (0.3 g/kg,0.6 g/kg,1.2 g/kg) and swimming abilities were tested.Other mice were administrated single dose of compound rhodiola( 1.2 g/kg) and training by Morris water maze.Drug's improving intelligence function was assessed using memory acquisition impaired models made by scopolamine or alcohol.When the Morris water maze test was finished,mice were killed and brains were removed immediately to measure SOD and NO levels.ResultsGroups of three doses of compound rhodiola could significantly prolong the swimming time(P ＜ 0.05,P ＜ 0.01 ).Compound Rhodiola group can significantly reduce the swimming distance than the untreated group( ethanol model group:(26 906.6 ± 2769.7 ) mm,RCE treated group:( 19 586.1 ± 6826.7 ) mm ; P ＜0.05 ).Swimming distance and time of cross-platform quadrant was significantly increased,comparing with model group (P ＜ 0.05 ).Compound Rhodiola significantly enhanced the activity of mouse brain's SOD ( Scopolamine model group:( 150.3 ± 17.7 ) U/ml,RCE treated group:( 197.9 ± 16.8 ) U/ml ; P ＜ 0.05 ) and NO levels ( Scopolamine model group:( 44.7 ± 16.7 ) μmol/gprot,RCE treated group:( 65.4 ± 14.5 ) μmol/gprot ; P ＜ 0.05 ) significantly.ConclusionCompound Rhodiola could promote mice learning and memory function,SOD and NO in brain maybe play a important role in this effect.
ABSTRACT
Objective To explore the influence of psychological intervention on quality of life(QOL) in the hysteromyoma patients underwent surgery. Methods Three hundred and twenty patients with hysteromyoma were divided into the psychological intervened group ( all cases were treated with the comprehensive psychological intervention) and the control group (without intervention). Before and after treatment, the scores of the Olson's Enrich Questionary and the Nottingham Health Poofity (NHP) were assessed in the two groups. Results Before surgery, the scores of N HP and Olson were not significantly different between the psychological intervened group and the control group ( P > 0. 05 ). The scores of NHP of total hysterectomy in the control group after surgery were higher than that before surgery,and the scores of Olson were lower significantly ( P <0. 05 or P <0. 01). The scores of NHP of subtotal hysterectomy, myomectomy and blood vessel involvement treatment in the control group after surgery were significantly lower than that before surgery, and the scores of Olson were higher ( P < 0. 05 or P < 0. 01 ). After surgery,the scores of NHP of all patients in the psychological intervened group were significantly lower than that in the control group,and the scores of Olson were higher significantly (P <0. 05 or P <0. 01). There was no significant difference in ovarian hormones level between pre- and post- surgery (P > 0. 05). Conclusions The comprehensive psychological intervention pre- and post- surgery is good for the quality of life in hysteromyoma patients.
