ABSTRACT

OBJECTIVE To expl ore the mechanism of effe ctive fractions from Xiongma decoction in the treatment of migraine with hyperactivity of liver-yang and blood stasis. METHODS Totally 70 male SD rats were randomly divided into normal group , model group ,positive control group (Flunarizine hydrochloride capsules 0.9 mg/kg),low-dose and high-dose groups of Xiongma decoction effective fractions (ethyl acetate extract 0.87,3.46 g/kg,n-butanol extract 1.80,7.20 g/kg). Except for normal group , rats in other groups were given aconite decoction (2 g/kg),once a day ,for 4 consecutive weeks to establish the hyperactivity model of liver-yang. On the 15th day of modeling ,all administration groups were given corresponding drugs intragastrically at the same time ,once a day ,for 2 consecutive weeks. On the 29th day of modeling ,rats trigeminal ganglion was stimulated to establish the migraine model with hyperactivity of liver-yang and blood stasis ,then the medication was maintained for another time according to the above method. The macroscopic signs and behavior of the rats were observed ;positive expression ,mRNA and protein expression of transient receptor potential vanilloid 1 (TRPV1),calcitonin generelated peptide (CGRP),calcitonin receptor-like receptor (CRLR) and receptor-associated membrane proteins 1 (RAMP1) in trigeminal cervical spinal complex (TCC) were detected by immunohistochemistry ,RT-qPCR and Western blot assay. RESULTS Rats in model group showed macrophysical signs and behaviora l manifestations related to migraine with hyperactivity of liver-yang and blood stasis. Thirty minutes after last administration ,the above conditions of rats in Xiongma decoction effective fraction groups were improved significantly. Compared with normal group , positive expression,mRNA and protein expression of TRPV 1,CGRP, CRLR and RAMP 1 in TCC of rats in the model group were significantly increased (P<0.05). Compared with model zengguirong@hnse.org group, most of above indicators in Xiongma decoction effective fraction groups were significantly decreased (P<0.05). CONCLUSIONS The mechanism of Xiongma decoction in preventing and treating migraine with hyperactivity of liver-yang and blood stasis may be related to inhibit the activity of TRPV1-CGRP/CGRP receptor signaling pathway in TCC.

ABSTRACT

Objective:To compare the efficacy of individualized PEEP determined by lung electrical impedance tomography (EIT) and dynamic lung compliance (Cdyn) during lung-protective ventilation strategies in the patients undergoing general anesthesia.Methods:Sixty patients of both sexes, aged 18-64 yr, of American Society of Anesthesiologists physical status Ⅰor Ⅱ, with body mass index of 18.5-28.0 kg/m 2, undergoing elective surgery with general anesthesia and endotracheal intubation in the Second Affiliated Hospital of Soochow University, were selected.Lung-protective ventilation strategy was applied in supine position after general anesthesia.The peak value of PEEP did not exceed 10 cmH 2O, with an increment/decrement of 2 cmH 2O for titration.The corresponding Cdyn value and lung EIT data were collected during titration.The patients were divided into 2 groups ( n=30 each) using a random number table method: titration first increased and then decreased group (group A) and titration first decreased and then increased group (group B). The determination method of individualized PEEP: Cdyn method was the PEEP corresponding to the maximum Cdyn value; EIT method was obtained through PV500 PC software analysis.The level and success rate of individualized PEEP determined by the Cdyn and EIT methods were compared, and the ICC consistency analysis of the determined individualized PEEP was performed. Results:Compared with the Cdyn method, the success rate of individualized PEEP determined by EIT method was significantly increased, and the level of individualized PEEP was decreased in the two group ( P<0.05). In group A, the individualized PEEP titrated by the EIT and Cdyn methods showed good agreement (the ICC value of the increment-Cdyn and increment-EIT methods was 0.761, P<0.05; the ICC value of the decrement-Cdyn and decrement-EIT methods was 0.763, P<0.05). In group B, the individualized PEEP titrated by the EIT and Cdyn methods showed good agreement (the ICC value of the increment-Cdyn and increment-EIT methods was 0.809, P<0.05; the ICC value of the decrement-Cdyn and decrement-EIT methods was 0.797, P<0.05). Conclusion:The agreement between the individualized PEEP determined by lung EIT method and Cdyn method during lung-protective ventilation is good in the patients undergoing general anesthesia, and the success rate of EIT method is higher, and the level of individualized PEEP is lower.

ABSTRACT

Objective:To establish the reference interval of serum triglyceride (TG) for 4 hours after meal in healthy middle and old people of Beijing community, and to provide the diagnostic basis for the judgment of dyslipidemia after meal.Methods:Selected 369 elderly people from January to October 2018 in the health examination of Guang′anmen Hospital of the Chinese Academy of Traditional Chinese Medicine. The subjects collected fasting venous blood samples in the morning the next day after fasting for 12 hours, then ate a standard breakfast that conformed to the local dietary habits, and collected venous blood samples again 4 hours after eating. Serum TG levels were measured 4 h after meal using AU5822 fully automatic biochemical analyzer and matching reagents. The comparison of postprandial TG between different age and sex groups was statistically significant using the nonparametric test of two independent samples, and the comparison between postprandial and fasting TG using the nonparametric test of two paired samples with P<0.05 as the difference. The 95% confidence interval was calculated using a nonparametric method according to the relevant requirements of the CLSI EP28-A3c file, and the reference interval was expressed as P2.5, P97.5. Results:The median 4-hour post-prandial TG of the middle-aged and elderly aged 45-59 years and those aged ≥ 60 years at health checkups were 1.65 (1.25, 2.13) mmol/L and 1.58 (1.25, 2.00) mmol/L, there was no significant difference between the two groups ( Z=-1.040, P>0.05). There was no statistical difference between males 1.69 (1.22, 2.31) mmol/L and females 1.63 (1.26, 2.12) mmol/L at 4 hours postprandial TG levels in the 45-59 year-old group ( Z=-0.179, P>0.05),there was also no statistical difference between 1.64 (1.22, 2.06) mmol/L for men and 1.53 (1.28, 1.99) mmol/L for women aged 60 years or older ( Z=-0.256, P>0.05).Compared with the median fasting TG of 1.05 (0.87, 1.29) mmol/L, the median serum TG of 1.61 (1.25, 2.09) mmol/L at 4 hours after meal was significantly increased ( Z=-16.449, P<0.01). The difference between postprandial and fasting was 0.52 (0.30, 0.85) mmol/L.The reference range of serum TG at 4 hours after meal was 0.82 to 3.02 mmol/L. Conclusion:In this study, the reference range of serum triglycerides for 4 hours after meal was established in some healthy elderly population groups in Beijing.

ABSTRACT

Objective:To analyze the pathological features of facioscapulohumeral muscular dystrophy (FSHD). For better characterization of inflammatory response in FSHD, we performed histochemical morphological analysis for FSHD and polymyositis (PM) muscle biopsies.In order to provide a reference for guide targeted therapeutic interventions.Methods:The clinical and myopathological data of 30 patients with FSHD from January 2006 to January 2019 in the Sixth Hospital of Shanxi Medical University and the first hospital of Jilin University were retrospectively analyzed. The patients were divided into non-inflammatory infiltration group (16 cases) and inflammatory infiltration group (14 cases) according to the presence or absence of inflammatory cell infiltration. For better characterization of inflammatory response in FSHD, we performed histochemical morphological analysis for two groups of muscles: FSHD and PM muscle biopsies, using Image-Pro plus bioanalytical software.Results:In 30 cases of FSHD, 14 cases showed intramuscular and interstitial inflammatory cell infiltration, especially around the blood vessels. Immunohistochemical staining confirmed that the infiltration of inflammatory cells was mainly CD4 + T lymphocytes. Morphometric analysis showed that there were no significant differences in muscle fiber surface area, density, diameter, inflammatory cell infiltration, regeneration and necrosis between FSHD patients and PM patients ( P>0.05). The total area of myointerstitium in FSHD group was significantly larger than that in PM group ( P=0.03). Conclusions:The pathological morphometric analysis showed that the proliferation of interstitial connective tissue in FSHD inflammatory cell infiltration group was significantly more than that in PM group. Clinicians can identify the two from pathology and provide help for clinical practice.

ABSTRACT

BACKGROUND: The molecular mechanism and core regulatory network of deep vein thrombosis are not fully clarified yet.OBJECTIVE: To explore the roles of oxidative stress and Rac1/2 in rat deep vein thrombosis.METHODS: Deep vein thrombosis model in SD rats was established by a champing method femoral veins clamping combinedwith fixation of the lower extremity with plaster. The incidence and serious degree of thrombus were observed by dissecting ratfemoral vein at different time points (2.5 and 25 hours after modeling). The model rats were divided into pre-thrombogenesisgroup (2.5 hours after modeling), thrombogenesis group (25 hours after modeling) and non-thrombogenesis group (25 hours aftermodeling). Then total RNA and protein were extracted from the femoral venous wall tissues.RESULTS AND CONCLUSION: Colorimetry results showed that compared with the non-thrombogenesis group, theconcentration of malondiadehyde in rat femoral vein wall tissues of the thrombogenesis group was the highest (P < 0.05), followedby that of the pre-thrombogenesis group (P < 0.05). The concentrations of total superoxide dismutase and glutathione reductasein the thrombogenesis group were the lowest, followed by those in the pre-thrombogenesis group (P < 0.05). The results of genechip hybridization analysis and real-time PCR showed that compared with the non-thrombogenesis group, the expressions ofRac1 and Rac2 in rat femoral vein wall tissues of thrombogenesis group increased the most, followed by that of thepre-thrombogenesis group (P < 0.05). These findings indicate that the up-regulation of malondialdehyde and Rac1/2 as well asthe activity decrease of total superoxide dismutase and glutathione reductase may lead to the formation of deep venousthrombosis.

ABSTRACT

BACKGROUND: At present, the basic underlying molecular mechanism regulating the interactions among venous endothelial cells, platelets, leukocytes, and promoting local deep vein thrombosis microenvironment formation, still remains unclear, and there is no ideal method for early diagnosis of deep vein thrombosis. OBJECTIVE: To study the underlying role of nuclear factor kappa B1 and tissue factor in rats with deep vein thrombosis. METHODS: A total of 67 Sprague-Dawley rats were randomly divided into control group (n=10) and model group (n=57). Deep vein thrombosis model was established by a clamping and sewing method in femoral vein combined with cast fixation. The incidence and serious degree of thrombus were observed by dissecting rat femoral vein in different time points (2.5 and 25 hours after modeling). The model group was further divided into pre-thrombogenesis group (2.5 hours after modeling), thrombogenesis group (25 hours after modeling) and non-thrombogenesis group (25 hours after modeling). Then total RNA was extracted from the localized femoral venous endothelial tissue. The candidate genes, associated inflammation and thrombosis, were screened by a special gene chip. Then the gene expression of nuclear factor kappa B1 and tissue factor was further identified by real-time polymerase chain reaction. RESULTS AND CONCLUSION: Pre-thrombogenesis group had no thrombogenesis, while thrombogenesis group have 23 cases with thrombosis and non-thrombogenesis group have 22 cases without thrombosis. The results of gene chip hybridization analysis and real-time PCR found that the mRNA expression of nuclear factor kappa B1 and tissue factor in rat femoral vein endothelial tissue were significantly up-regulated at 2.5 hours after modeling (pre-thrombogenesis group was higher than control group) (P < 0.05), and continued up-regulating at 25 hours after modeling (thrombogenesis group was higher than the pre-thrombogenesis group, non-thrombogenesis group and control group) (P < 0.05). The results from present study indicate that up-regulating expressions of nuclear factor kappa B1 and tissue factor in local femoral venous endothelial tissue of rat deep vein thrombosis models may play a key role in initiating venous thrombosis.

ABSTRACT

Blood samples were collected from 90 patients with confirmed rheumatoid arthritis (RA), 73 patients with other rheumatic diseases and 50 normal controls. Serum glucose-6-phosphate isomerase (GPI) and anti-cyclic citrullinated peptide (CCP) were detected with ELISA method, rheumatoid factor IgM( RF IgM)was measured with turbidimetric immunoassay and antikeratin antibody (AKA) was determined with indirect immunofluorescence assay. The serum GPI levels of RA group[1.73 (0. 43 -4. 40)mg/L]were significantly higher than those of rheumatic disease[0. 14 (0. 10 -0. 18 )mg/L]and normal controls[0. 12 (0. 09 - 0. 15 ) mg/L], ( H = 18. 13, P < 0. 01 ). The sensitivities of GPI, anti-CCP,RF-IgM, AKA, GPI + CCP, GPI + RF-IgM were 80% (72/90), 57% (51/90), 68% (61/90), 29% (26/90) ,92% (83/90) and 96% (86/90), respectively; the specificities were 97% (119/123) ,95% ( 117/123 ) ,77% (95/123) ,95% ( 117/123 ), 93% ( 115/123 ) and 76% ( 93/123 ), respectively. GP1 level was significantly correlated with CCP and RF-IgM ( r = 0. 674 and 0. 533, P < 0. 01 ), but not correlated with AKA ( r = 0. 12, P > 0. 05 ). The results suggest that serum glucose-6-phosphate isomerase level is a valuable indicator for early diagnosis of rheumatoid arthritis.

ABSTRACT

Objective To investigate the effect of sevoflurane (Sero) preconditioning (Precon) on cardiomyocyte apoptosis following myocardial ischemia-reperfusion (I/R) in rats. Methods Sixty-four adult male SD rats weighing 270-350 g were randomly divided into 4 groups ( n = 16 each): group Ⅰ sham operation (group S); group Ⅱ myocardial I/R; group Ⅲ Sero and group Ⅳ Sevo-Precon + myocardial I/R. The animals were anesthetized with intraperitoneal pentobarbital 50 mg/kg, intubated and mechanically ventilated. PET CO2 was maintained at 35-45 mm Hg. Myocardial I/R was induced by 30 min occlusion of the left anterior descending branch of coronary artery followed by 2 h reperfusion in group Ⅱ and Ⅳ . In group Ⅲ the animals inhaled 2.5 % sevoflurane for 30 min while in group Ⅳ the animals inhaled 2.5% sevoflurane for 30 min at 15 min before myocardial I/R. Eight animals were killed at the end of 2 h reperfusion in each group. The hearts were removed for determination of myocardial infarct size (IS) as a percentage of area at risk (AAR) (IS/AAR) by triphenyl tetrazolium chloride staining. Myocardial apoptosis was detected using TUNEL and apoptosis index (AI) was calculated. Another 4 animals were killed before ischemia and at the end of 2 h reperfusion for determining the expression of Bcl-2 and caspase-3 protein in myocardium by Western blot. Results Sevoflurane preconditioning significantly decreased infarct size and AI in group Ⅳ as compared with group Ⅱ (group I/R). Bcl-2 protein expression was significantly decreased and caspase-3 protein expression was significantly increased after 2 h reperfusion as compared with the expression before ischemia in group I/R (group Ⅱ ). Sevoflurane preconditioning significantly reversed the I/R-induced changes in Bcl-2 and caspase-3 protein expression. Conclusion Sevoflurane preconditioning can attenuate myocardial I/R injury by decreasing myocardial apoptosis.

The lowest spore concentration they could be detected was 10 CFU/ml, which equated to 100-1000 copies of internal transcribed spacer (ITS)2 genes, suggesting a good sensibility. They didn't have cross-positive reaction with other fungus, human genome and bacteria, which indicated a good specificity. Conclusion The diagnostic technique based on the AllGlo?probe for the invasive aspergillosis possessed a good sensitivity, good specificity and deadly accuracy.

ABSTRACT

Purpose To observe the action time of parthenolide (PTN) as selective nuclear factor-κB(NF-κB) inhibitor in heart of rats.Methods Forty SD rats were randomly divided into control(CON) group,PTN group,dimethyl sulfoxide(DMSO) group,lipopolysaccharide(LPS) group and PTN+LPS group.The first day:PTN group,DMSO group and PTN+LPS group rats were respectively injected interapertoneally PTN(500 μg/kg) and DMSO; other groups rats were injected interapertoneally equivalent saline.The second day(in equivalent to 24 h after injecting PTN):in LPS group and PTN+LPS group LPS(12.5 mg/kg) was administered subcutaneously; other group rats were injected subcutaneously equivalent saline.Every heart was obtained in equivalentce to 1 h after injecting LPS to measure the expression of NF-κB p50 in nucleus,inhibitory kappaB(IκBα) and phosphorylation inhibitory kappaB(p-IκBα) in cytoplasm of cardiac myocytes through Western blotting.Results Compared with CON group,the expression of NF-κB p50,IκBα and p-IκBα had no difference in PTN and DMSO group.And in LPS group and PTN + LPS group,the expression of NF-κB p50 up-regulated significantly(P<0.05),IκBα down-regulated(P<0.05) and p-IκBα up-regulated significantly(P<0.05).Conclusion LPS can activate NF-κB in 1 h and PTN in rats after 24 h has few effect.

ABSTRACT

Objective To observe the effects of triptolide(TPL) on the anti-oncogene-APC gene of acute lymphoblastic leukemia cell line Jurkat in vitro. Methods The effects of TPL on proliferation Jurkat cells were assayed by using cell culture, MTT. The effects of TPL on APC gene of Jurkat cells were analyzed by nested methylation specific PCR and RT-PCR. The effects of TPL on the proteinum expression of APC gene were detected by Western blotting analysis. Results Following the treatment of TPL, the cell proliferation rate was degraded as the treatment concentration increased and the culture time extended. The effects were dose and time-dependent. The 48 hour IC50 was 19.7 ng/ml. TPL can reverse hypermethylation of APC gene,and induce the expression of the mRNA and the proteinum. Conclusion Low dose TPL could depress the proliferation rate of Jurkat. The possible mechanism might be its reversing the hypermethylation of APC gene and activiting the expression of APC gene.
