To investigate the changes of anesthetic drug concentration in plasma during isolation of autologous blood with acute normovolemic hemodiluti-on and its influence on the depth of anesthesia, muscle relaxant effect and blood drug concentration after reinfusion. METHODS: Forty patients of both sexes, aged 20-60 yr, American Society of Anesthesiologists physical status or Ⅱ, hemoglobin (Hb) >120 g / L, hematocrit (Hct) >35%, undergoing eletive multilevel spinal surgery were included, were divided into 2 groups (n=20 each) using a random number table. ANH group (group A): ANH was performed after stable induction of anesthesia, the target Hct value was 28%-30%, and autologous blood was reinfused after the main operation steps. Control group (group C): routine transfusion and infusion treatment. The bispectral index (BIS) and Train-of-Four stimulation (TOF) were observed and recorded at the stable induction of anesthesia (T1), 30 minutes of stable induction (T2), the end of operation (T3), 30 minutes after the end of the operation (T4), 1 hour after the end of the operation (T5) and 2 hours after the end of the operation (T6). The concentrations of propofol and cisatracurium besylate in plasma at T1-T6, stored blood at 1 h (TS1), 2 h (TS2), and before reinfusion (TS3) were detected by Liquid Chromatography-tandem Mass Spectrometry. The extubation time and recovery score at T4-6 hours were recorded. RESULTS: There was no significant difference in propofol between the two groups at each time point (P > 0.05). The plasma concentration of cisatracurium besylate in group A was higher than that in group C at T3 (P0.05). The BIS value at T4 and TOF value at T3 in group A were significantly lower than those in group C. The recovery score of group A was lower than that of group C at T4 (P0.05). CONCLUSION: The plasma concentrations of propofol and cisatracurium besylate were basically unchanged during the in vitro isolation of ANH autologous blood. The plasma concentrations of cisatracurium besylate were only temporarily affected after the main operation steps, but the postoperative muscle relaxation recovery and recovery quality were not significantly affected.

Results:After treatment, the knee flexion [(96.43 ± 4.63) ° vs. (89.58 ± 4.67) °, t=6.59] in the observation group was higher than that of the control group ( P<0.01), and the extension [(8.32 ± 2.03) ° vs. (11.69 ± 2.37) °, t=6.83] in the control group was lower than that of the control group ( P<0.01); VAS score (2.06 ± 0.49 vs. 3.65 ± 0.76, t=11.12) was lower than that of the control group ( P<0.01), and Fugl Meyer motor function score (28.97 ± 3.76 vs. 20.43 ± 3.04, t=11.17) was higher than that of the control group ( P<0.01). Conclusion:The application of modern rehabilitation techniques combined with TCM external application in the treatment of knee stiffness can improve the range of motion of the knee joint, reduce the VAS score of pain, and improve the motor function.

Baimai Ointment relieves chronic pain induced by chronic compression of dorsal root ganglion in rats by regulating neuroactive ligand-receptor interaction and HIF-1 signaling pathway / 中国中药杂志

The Baimai Ointment with the effect of relaxing sinew and activating collaterals demonstrates a definite effect on Baimai disease with pain, spasm, stiffness and other symptoms, while the pharmacodynamic characteristics and mechanism of this agent remain unclear. In this study, a rat model of chronic compression of L4 dorsal root ganglion(CCD) was established by lumbar disc herniation, and the efficacy and mechanism of Baimai Ointment in the treatment of CCD were preliminarily explored by behavioral tests, side effect evaluation, network analysis, antagonist and molecular biology verification. The pharmacodynamic experiment indicated that Baimai Ointment significantly improved the pain thresholds(mechanical pain, thermal pain, and cold pain) and gait behavior of CCD model rats without causing tolerance or obvious toxic and side effects. Baimai Ointment inhibited the second-phase nociceptive response of mice in the formalin test, increased the hot plate threshold of normal mice, and down-regulated the expression of inflammatory cytokines in the spinal cord. Network analysis showed that Baimai Ointment had synergistic effect in the treatment of CCD and was related to descending inhibition/facilitation system and neuroinflammation. Furthermore, behavioral tests, Western blot, and immunofluorescence assay revealed that the pain-relieving effect of Baimai Ointment on CCD may be related to the regulation of the interaction between neuroactive ligand and receptors(neuroligands) such as CHRNA7, ADRA2A, and ADRB2, and the down-regulation of the expression of NOS2/pERK/PI3K, the core regulatory element of HIF-1 signaling pathway in spinal microglia. The findings preliminarily reveal the mechanism of relaxing sinew and activating collaterals of Baimai Ointment in the treatment of Baimai disease, providing a reference for the rational drug use and further research of this agent.

Effect of Physical Training on Nitric Oxide Levels in Patients with Arterial Hypertension: An Integrative Review

Abstract The regular practice of physical exercise as a non-pharmacological treatment of arterial hypertension (AH) has been encouraged due to causing a series of physiological responses in the cardiovascular system, such as the production of vasoactive substances, including nitric oxide (NO). NO is a relaxation factor released by the endothelium, and the decrease in its bioavailability is related to coronary and arterial diseases, such as AH. This study aimed to perform an integrative literature review to elucidate the effect of physical training on NO levels in patients with AH and to establish a relationship between these levels and blood pressure (BP) control. A literature review was was performed by searching PubMed / MEDLINE, Lilacs, Scielo, Cinahl and Embase databases. The search string used was ("arterial hypertension" OR hypertension) AND (exercise OR "physical exercise" OR "aerobic exercise" OR "exercise training" or "physical activity") AND ("nitric oxide"). We included fully available controlled and uncontrolled clinical trials published in English and Portuguese languages in the last 10 years. The review consisted of 16 articles, of which 13 reported an increase in NO production after the physical training intervention, and three studies found no change. In addition, 15 studies observed a reduction in BP after the intervention. In conclusion, regular practice of physical exercises, advocating moderate intensity, can improve NO bioavailability in pre-hypertensive and hypertensive individuals, which seems to be one of the mechanisms responsible for BP reduction.

Analysis on formulation regularity and characteristics of acne-relieving Chinese medicinal health products and Chinese patent medicines / 中国中药杂志

This study summarized and analyzed the current acne-relieving Chinese medicinal health products and Chinese patent medicines,aiming at providing references for the formulation and development of acne-relieving health products. The information on acne-relieving health products published by the Department of Special Food Safety Supervision and Management,the State Administration for Market Regulation( SAMR) was retrieved,and the Chinese patent medicines on DRUGDATAEXPY were searched. Microsoft Excel and the Traditional Chinese Medicine Inheritance Support System V2. 5( TCMISS) were employed to statistically analyze the characteristics of formulations. Forty-three acne-relieving health products were obtained,including 40 ones containing Chinese herbal medicines. Six Chinese herbal medicines showed a usage frequency ≥8,with 61 times in use totally,including Salviae Miltiorrhizae Radix et Rhizoma( 13),Lonicerae Japonicae Flos( 12),Taraxaci Herba( 11),ALOE( 9),Carthami Flos( 8),and Rhei Radix et Rhizoma( 8). A total of 29 Chinese patent medicines with similar efficacy were collected in DRUGDATAEXPY. Nine Chinese herbal medicines showed a usage frequency ≥6,with 63 times in use,including Rhei Radix et Rhizoma( 10),Glycyrrhizae Radix et Rhizoma( 8),Scutellariae Radix( 8),Lonicerae Japonicae Flos( 7),Angelicae Sinensis Radix( 6),Paeoniae Radix Rubra( 6),Astragali Radix( 6),Paeoniae Radix Alba( 6),and Gardeniae Fructus( 6). Through unsupervised hierarchical entropy-based clustering of the above-mentioned Chinese medicinal health products and Chinese patent medicines,five and three new formulas were obtained,respectively. The selection of Chinese herbal medicines was consistent with the principles of traditional Chinese medicine( TCM) theories in relieving acne,i. e.,dispelling exterior wind,ventilating lungs,clearing heat,dissipating mass,promoting diuresis,relaxing bowels,removing toxin,activating blood,resolving stasis,eliminating phlegm,and regulating Qi. According to the " lung governing skin and body hair" and " interior-exterior relationship between lung and large intestine" in TCM theories,the idea that acne could be treated by relieving constipation was proposed,which provided new methods and references for the research and development of Chinese medicinal health products.

Identification of intestine direct targets of Shouhui Tongbian Capsules using "target fishing" strategy / 中国中药杂志

"Target fishing" strategy was used to investigate the direct targets and mechanism of Shouhui Tongbian Capsules on relaxing bowel. Magnetic beads cross-linked with the chemical constituents from Shouhui Tongbian Capsules were prepared. The potential target proteins were captured from the total protein lysates of rat intestine using the beads. The captured proteins were further identified by LC-MS/MS, and the associated pathways were analyzed by Cytoscape. RESULTS:: showed that 138 potential target proteins were identified, which were involved in eight signaling pathways, including tricarboxylic acid cycle, pyrimidine metabolism, sulfur metabolism, fatty acid degradation, alanine/aspartate/glutamate metabolism, arginine/proline metabolism, valine/leucine/isoleucine degradation, and β-alanine metabolism. Taken together, Shouhui Tongbian Capsules may exert relaxing bowel effect by acting on multiple signaling pathways to promote intestinal gurgling, inhibit inflammation, as well as improve intestinal barrier function, intestinal water secretion, and intestinal flora.

Here, based on previously published research articles, monographs, patents as well as practice experiences, the research progresses on the internal and external factors affecting bolting and flowering of A. sinensis, the pathways regulating bolting and flowering, the mechanism revealing bolting and flowering by biotechnological interventions were summarized, with the aim of providing effective pathways jointly internal and external factors for regulating bolting and flowering, as well as references for further revealing the mechanism of the bolting and flowering of A. sinensis.

Comparison of therapeutic effect of soft-tissue relaxing needling and electroacupuncture for knee osteoarthritis / 针刺研究

OBJECTIVE: To compare the clinical efficacy of soft-tissue relaxing needling and electroacupuncture (EA) in the treatment of knee osteoarthritis (KOA), so as to explore a new and more effective therapy for KOA. METHODS: Forty patients with KOA who met our diagnostic criteria were randomly and equally divided into acupuncture group and soft-tissue relaxing needling (relaxing-needling) group. EA (20 Hz, a tolerable strength and duration of 20 min) was applied to the unilateral Neixiyan(EX-LE5) and Waixiyan(EX-LE5), and manual acupuncture stimulation was applied to Heding(EX-LE2), Xuehai (SP10), Xiyangguan (GB33), Liangqiu(ST34), Yanglingquan(GB34) and Yinlingquan(SP9) on the affected side by using uniform reinforcing-reducing technique. In the relaxing-needling group, after identifying the tender point and nodule-like or stiff-strip-muscle spot at the affected limb by palpation, we used filiform needles to insert into them, then, made a longitudinal separation or point-like pricking. The visual analog scale (VAS) pain score, knee flexion activity (range of motion, ROM), and the knee osteoarthritis severity (Lequesne index, composed of daily living, walking distance and pain) were measured before and after the treatment. The therapeutic effect was assessed by consulting the Guiding Principles for Researching New Drugs of Traditional Chinese Medicine (2002) and Criteria for Diagnosis and Assessment of Therapeutic Effect of Syndromes or Illnesses of Traditional Chinese Medicine (1994). RESULTS: After the treatment, the VAS score and Lequesne index were significantly decreased in both acupuncture and relaxing-needling groups (P0.05)．. CONCLUSION: Both relaxing-needling and EA therapies are comparable in the therapeutic effect for KOA, and the former is superior to the latter in reducing the joint pain and improving the knee joint locomotor function, thus being worthy of clinical application.

Knockdown of transglutaminase-2 prevents early age-induced vascular changes in mice

Abstract Purpose: To determine whether the absence of transglutaminase 2 enzyme (TG2) in TG2 knockout mice (TG2-/-) protect them against early age-related functional and histological arterial changes. Methods: Pulse wave velocity (PWV) was measured using non-invasive Doppler and mean arterial pressure (MAP) was measured in awake mice using tail-cuff system. Thoracic aortas were excised for evaluation of endothelial dependent vasodilation (EDV) by wire myography, as well as histological analyses. Results: PWV and MAP were similar in TG2-/-mice to age-matched wild type (WT) control mice. Old WT mice exhibited a markedly attenuated EDV as compared to young WT animals. The TG2-/-young and old mice had enhanced EDV responses (p<0.01) as compared to WT mice. There was a significant increase in TG2 crosslinks by IHC in WT old group compared to Young, with no stain in the TG2-/-animals. Optical microscopy examination of Old WT mice aorta showed thinning and fragmentation of elastic laminae. Young WT mice, old and young TG2-/-mice presented regularly arranged and parallel elastic laminae of the tunica media. Conclusion: The genetic suppression of TG2 delays the age-induced endothelial dysfunction and histological modifications.

The IL-1β, IL-6 and TNF-α levels of inflammatory factors were detected by enzyme-linked immunosorbent assay.Results The total effective rate of patients in research roup was significantly higher than that of the control group [90.20％ (46/51)vs. 43.14％ (22/51),χ2=19.329, P=0.006]. After treatment, the VAS scores of patients in both groups were significantly decreased, and JOA score increased markedly, which the differences were statistically significant (Ps<0.05). After treatment, the VAS score of research group was significantly lower than the control group (4.26 ± 0.56vs. 5.13 ± 0.87;t=4.843, P=0.027), and JOA score was significantly higher than the control group (18.42 ± 3.92vs.17.33 ± 4.21;t=5.127, P=0.022). After treatment, the IL-1β, IL-6 and TNF-α levels of of patients in the research group were significantly lower than those of the control group (0.57 ± 0.11μg/Lvs. 0.90 ± 0.13μg/L, 112.26 ± 15.17μg/Lvs. 130.38 ± 18.29μg/L, 2.01 ± 0.34μg/Lvs. 2.37 ± 0.51μg/L;t=5.429, 6.317, 5.011,P<0.05). ConclusionsThe Taohong-Siwu decoction combined with manipulation on treatment of the acute phase of LDH was effective. The combined therapy can improve the VAS score and JOA score, and reduce the levels of inflammatory cytokines.

The lectin isolated from Lonchocarpus araripensis seed elicits endothelium-dependent vasorelaxation / A lectina isolada de sementes de Lonchocarpus araripensis promove efeito vasorelaxante dependente de endotélio

Background: The vasorelaxant effect of lectins from leguminous plants (Diocleinae subtribe) is well described. However, this effect has been little explored for lectins isolated from Dalbergieae tribe, except for that of Vatairea guianensis, that induces vasorelaxation involving nitric oxide and the lectin domain. Objective: To evaluate the vasorelaxant effect of a lectin isolated from Lonchocarpus araripensis (LAL), Dalbergieae tribe, and the involvement of the lectin domain and endothelium derived relaxing factors. Methods: Aortic rings of Wistar rats (250 - 300 g) were mounted in organ bath and mantained in physiological conditions (CEUA No. 10130208-8/40). LAL (0.1­100 µg/ml) was added to phenylephrine (0.1 µM)-contracted tissues with either endothelium intact or denuded. In order to investigate the mechanisms of LAL relaxation, inhibitors of NOS (L-NAME: 100 µM), cyclooxygenase (indomethacin: 10 µM), or potassium channels (TEA: 5 mM) were added to endothelized tissues 30 min before contraction. The involvement of lectin domain was assessed by previous incubation of LAL (30 µg/ml) with GlcNAc (0.1 M). Results: LAL (0.1-100 µg/ml) induced relaxation only in endothelized aorta, being maximal at 100 µg/ml (62.57 ± 7.8%). The relaxant effect induced by LAL at 30 µg/ml (52.49 ± 10.32%) was abolished by previous incubation with GlcNAc. LAL relaxant effect (IC50 9.75 ± 7.1) was partially reversed by indomethacin (IC50 LAL + indomethacin: 30.47 ± 10.93) and was abolished by L-NAME or TEA. Conclusion: LAL exhibits vasorelaxant activity in contracted endothelized aorta of rats, involving the lectin domain, muscarinic receptor of acetylcholine and endothelial derived relaxing factors.

Introdução: O efeito vasorrelaxante de lectinas de plantas leguminosas (Subtribo Diocleinae) já é bem descrito, embora pouco explorado para lectinas isoladas da tribo Dalbergieae, com exceção da lectina de Vatairea guianensis, que induz relaxamento com envolvimento de óxido nítrico e do domínio lectínico. Objetivo: Avaliar o efeito vasorrelaxante da lectina isolada de Lonchocarpus araripensis (LAL), tribo Dalbergieae, e o envolvimento do domínio lectínico e de fatores relaxantes derivados do endotélio (EDRF). Métodos: Anéis de aorta de ratos Wistar (250-300 g) foram montados em banho de órgãos em condições fisiológicas (Tyrode, 37 ° C, 95% de O2 e 5% de CO2, pH = 7,4) (CEUA No. 10130208-8/40). LAL (0,1-100 µg/ml) foi adicionada a tecidos pré-contraídos com fenilefrina (0,1 µM) com ou sem endotélio. Para investigar os mecanismos de relaxamento, foram adicionados inibidores de NOS (L-NAME: 100 µM), guanilato ciclase (ODQ: 10 µM), receptor muscarínico (atropina: 1 µM), ciclooxigenase (indometacina: 10 µM) ou canais de potássio (TEA: 5 mM) aos tecidos endotelizados 30 minutos antes da contração. O envolvimento do domínio lectínico foi avaliado por incubação prévia da LAL (30 µg/ml) com GlcNAc (0,1 M). Resultados: LAL (0,1-100 µg/ml) relaxou apenas anéis de aorta endotelizadas, com efeito máximo na dose de 100 µg/ml (62,57 ± 7,8%). O efeito relaxante da LAL a 30 µg/ml (52,49 ± 10,32%) foi abolido por incubação prévia com GlcNAc, atropina ou ODQ. O relaxamento da LAL (IC50 9,75 ± 7,1) a 10, 30 e 100 µg/ml foi parcialmente revertido por indometacina (IC50 LAL + indometacina: 30,47 ± 10,93) e abolido por L-NAME e TEA. Conclusão: A LAL exibe atividade vasorrelaxante em aorta endotelizada de ratos, no estado contraído, envolvendo o domínio lectínico, receptor muscarínico e fatores relaxantes derivados do endotélio.
