RESUMEN

Objective: To investigate the clinical efficacy and safety of percutaneous transforaminal endoscopic discectomy (PTED) in the treatment of multi-segmental lumbar disc herniation (msLDH). Methods: From January 2021 to December 2021, 75 patients with msLDH admitted to Baoding No.1 Hospital of Traditional Chinese Medicine were selected and divided into PTED group (n=40) and posterior lumbar interbody fusion (PLIF) group (n=35) according to different surgical methods. The operative time, intraoperative blood loss, surgical complications, Oswestry disability index (ODI) and Japanese Orthopedic Association score (JOA) scores were compared between the two groups. Results: In the PTED group, the average operation time was 57.45±12.01minutes, and the average intraoperative blood loss was 50.57±16.69ml. There were three patients with surgical complications, including one case of hematoma, one case of aggravation of neurological symptoms and one case of new onset of neurological symptoms. In the PLIF group, there were 12 cases undergoing single-segment operation, 15 cases undergoing double-segment operation and 8 cases undergoing three-segment operation, the average operation time was 137.26±34.64minutes, and the average intraoperative blood loss was 456.06±33.06ml, there were four cases of wound fat liquefaction or delayed healing, two cases of hematoma, and three cases of exacerbation of original neurological symptoms or new neurological symptoms. At one month, six months, and one year of postoperative, the ODI and JOA scores of the two groups were significantly improved compared with those preoperative, and the ODI scores of the PTED group were better than those of the PLIF group (t=3.131, 2.263, 3.768, all P<0.05). Conclusion: The surgical effect of PTED in the treatment of LDH is similar to that of PLIF. However, PTED has the advantages of short operation time, less blood loss, fewer surgical complications, and high surgical safety. It is worthy of clinical promotion.

RESUMEN

ObjectiveTo explore the hub genes of acute-on-chronic liver failure (ACLF) using bioinformatics methods, predict the potential traditional Chinese medicines (TCMs) against ACLF, and verify the treatment mechanism based on experiments. MethodPerl and R were used to analyze the GSE142255 dataset to obtain the differentially expressed genes (DEGs), from which the hub genes in the protein-protein interaction of DEGs were identified by five algorithms of the CytoHubba plug-in. The receiver operating characteristic (ROC) curve and GSE168048 dataset were then used to verify the hub genes. Coremine Medical was employed to map the TCMs corresponding to the hub genes and then the natures, tastes, and meridian tropism of the TCMs were analyzed. The TCM systems pharmacology database and analysis platform (TCMSP) and DEGs were used to obtain the common targets shared by high-frequency TCMs and ACLF, and Cytoscape was used to establish the "hub gene-high-frequency TCM-active ingredient-common target" network. Furthermore, gene ontology (GO) annotation, Kyoto encyclopedia of genes and genomes (KEGG) enrichment analysis, and in vitro experiments were performed. ResultA total of 388 DEGs were obtained, in which the 7 hub genes encoded CD4 integrin subunit alpha M (ITGAM), CD2, lymphocyte-specific protein tyrosine kinase (LCK) proto-oncogene, C-C motif chemokine ligand 5 (CCL5), matrix metallopeptidase-9 (MMP-9), and Fc epsilon receptor IG (FCER1G). The TCM candidates for treating ACLF were mainly cold, bitter, and had tropism to the liver meridian, among which the high-frequency TCMs (Hedyotis Diffusae Herba, Ganoderma, and Astragali Radix) and the active ingredients (quercetin, kaempferol, and beta-sitosterol) had significant therapeutic potential. The enrichment analysis results showed that TCMs acted on multiple targets and pathways such as autophagy, oxidative stress, and inflammatory cytokines in addition to regulating hub genes. L02 cell experiments showed that the quercetin group had lower levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and malondialdehyde (MDA), lower protein levels of ubiquitin-binding protein p62 and MMP-9, and higher levels of superoxide dismutase (SOD), glutathione (GSH), and microtubule-associated protein 1 light chain 3 Ⅱ/Ⅰ (LC3 Ⅱ/Ⅰ) than the D-galactosamine (D-GaLN) group (P<0.05, P<0.01). In addition, the pretreatment with 3-methyladenine (3-MA) inhibited the activating effect of quercetin on the autophagy of L02 cells. ConclusionThe potential TCMs and active ingredients predicted based on the hub genes of ACLF have a great research value. Quercetin has the potential to treat ACLF by inhibiting the D-GaLN-induced oxidative stress and inflammatory response in L02 cells and regulating the expression of MMP-9, which may be associated with the activation of autophagy.

RESUMEN

BACKGROUND: Ban-xia-xie-xin-tang (BXXXT) has been applied in treating metabolic diseases, such as nonalcohol fatty liver disease, diabetes mellitus, and obesity. However, the underlying molecular mechanism of BXXXT in treating diabetes mellitus is unknown. PURPOSE: To clarify the underlying molecular mechanism of BXXXT in alleviating hepatic steatosis in high-fat diet (HFD)-fed mice. METHODS: After 12 weeks of HFD treatment, mice were administered BXXXT for 4 weeks. The main chemical components of BXXXT were identified by UPLC-TQ-MS/MS. Indicators associated with insulin resistance and lipid metabolism were detected. The effect of improving glucose and lipid metabolism between BXXXT and the different components was compared. Differentially expressed genes (DEGs) were identified by hepatic transcriptomics. Key DEGs and proteins were further detected by real-time quantitative polymerase chain reaction, western blotting, immunohistochemistry, and immunofluorescence staining. LDs and mitochondria were detected by transmission electron microscopy. RESULTS: First of all, our data demonstrated that the capacity to improve glucose and lipid metabolism for BXXXT was significantly superior to different components of BXXXT. BXXXT was found to improve HFD-induced insulin resistance. Moreover, BXXXT decreased weight, serum/hepatic triglycerides, total cholesterol, and FFAs to alleviate HFD-induced hepatic steatosis. According to the results of the hepatic transcription, Cidea and Cidec were identified as critical DEGs for promoting LD fusion and reducing FFAs ß-oxidation in mitochondria and peroxisome resulting in hepatic steatosis, which was reversed by BXXXT. CONCLUSION: BXXXT ameliorates HFD-induced hepatic steatosis and insulin resistance by increasing Cidea and Cidec-mediated mitochondrial and peroxisomal fatty acid oxidation, which may provide a potential strategy for therapy of NAFLD and T2DM.

RESUMEN

OBJECTIVES@#To investigate the levels of fat-soluble vitamins A, D, and E in children with obesity and their influencing factors.@*METHODS@#A total of 273 children with obesity who attended the Department of Clinical Nutrition, Xi'an Children's Hospital, from January 2019 to April 2021 were enrolled as the obesity group. A total of 226 children with normal body weight who underwent physical examination during the same period were enrolled as the control group. Anthropometric parameters and body composition were measured for both groups, and the serum concentrations of vitamins A, D, and E were also measured.@*RESULTS@#Compared with the control group, the obesity group had significantly higher serum levels of vitamin A [(1.32±0.21) μmol/L vs (1.16±0.21) μmol/L, P<0.001] and vitamin E [(9.3±1.4) mg/L vs (8.3±1.2) mg/L, P<0.001] and a significant reduction in the level of 25-hydroxyvitamin D [(49±22) nmol/L vs (62±24) nmol/L, P<0.001]. In the obesity group, the prevalence rates of marginal vitamin A deficiency, vitamin D deficiency/insufficiency, and vitamin E insufficiency were 5.5% (15/273), 56.8% (155/273), and 4.0% (11/273), respectively. After adjustment for body mass index Z-score and waist-to-height ratio, serum vitamin A level was positively correlated with age (P<0.001), while vitamins E and 25-hydroxyvitamin D levels were negatively correlated with age in children with obesity (P<0.001). After adjustment for age, the serum levels of vitamin A, vitamin E and 25-hydroxyvitamin D were not correlated with degree of obesity, percentage of body fat, and duration of obesity in children with obesity, while the serum levels of vitamins A and E were positively correlated with waist-to-height ratio (P<0.001).@*CONCLUSIONS@#There are higher serum levels of vitamins A and E in children with obesity, especially in those with abdominal obesity, while serum vitamin D nutritional status is poor and worsens with age. Therefore, vitamin D nutritional status should be taken seriously for children with obesity, and vitamin D supplementation should be performed when necessary.

RESUMEN

Professor CHU Hao-ran believes that the clinical diagnosis and treatment of diarrhea-predominant irritable bowel syndrome with acupuncture and moxibustion should concentrate on the integration of disease and syndrome differentiation. According to the evolution of pathogenesis, this disease is divided into 4 stages, i.e. invasion of exogenous pathogens, liver stagnation and spleen deficiency, spleen and kidney yang deficiency and interaction of cold and heat. Hence, the treatment should be provided by stages. Focusing on regulating the spleen and stomach, a specific acupuncture-moxibustion prescription is proposed, including Tianshu (ST 25), Zhongwan (CV 12), Zusanli (ST 36) and Shangjuxu (ST 37). Additionally, the combination of distal and nearby acupoints is considered and an unique needling manipulation, named the fight between dragon and tiger, is exerted. On the base of syndrome and meridian differentiation, the modern medicine is combined, stressing on the mind regulation and the mutual application of acupuncture and moxibustion in treatment. Eventually, a distinctive treatment system with acupuncture and moxibustion is formed for "regulating the spleen and stomach and differentiating meridians".

RESUMEN

Objective:To investigate the effects of Huanglian Jiedutang on learning and memory ability and the cholinergic system in Alzheimer's disease(AD) rats induced by amyloid <italic>β</italic>-protein(A<italic>β</italic>)<sub>1-42</sub>. Method:Sixty male SD rats were divided into normal group, model group, huperzine A group (2.1×10<sup>-5</sup> g·kg<sup>-1</sup>), high-, medium- and low dose of Huanglian Jiedutang groups (6,3,1.5 g·kg<sup>-1</sup>). AD rat model was replicated by hippocampal injection of A<italic>β</italic><sub>1-42</sub>. After 4 weeks of treatment, Morris water maze test was performed. Hematoxylineosin (HE) staining was used to observe the pathological changes of rat hippocampus. Sampling blood from abdominal aorta was taken. Acetylcholine (ACh), acetylcholinesterase (AchE) and choline acetyltransferase (ChAT) in serum and hippocampus were detected by enzyme-linked immunosorbent assay (ELISA). The expression of hippocampal <italic>α</italic>7 nicotinic acetylcholine receptor (<italic>α</italic>7nAChR) protein was detected by Western blot. The expression of hippocampal <italic>α</italic>7nAChR mRNA was detected by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). Result:Compared with the normal group, there were obvious pathological changes in the model group,such as neuron necrosis in the cerebral cortex,pyramidal cell or granular cell necrosis in the hippocampus,disorder of arrangement and inflammatory cell infiltration,prolonged escape latency,decreased escape platform times,decreased residence time in the effective area and swimming path in the effective area (<italic>P<</italic>0.05,<italic>P<</italic>0.01). The contents of <italic>α</italic>7nAChR mRNA,ACh,AchE,ChAT,<italic>α</italic>7nAChR in the hippocampus decreased (<italic>P<</italic>0.01). Compared with the model group,the escape latency of the middle dose group was shorter (<italic>P<</italic>0.05), the escape platform times,the swimming path in the effective area and the residence time in the effective area increased (<italic>P<</italic>0.05,<italic>P<</italic>0.01), the contents of serum ACh,ChAT, hippocampal AchE,ChAT and <italic>α</italic>7nAChR increased (<italic>P<</italic>0.05,). The expression of hippocampal <italic>α</italic>7nAChR protein significantly increased (<italic>P<</italic>0.01), the residence time of effective area in high dose group was prolonged (<italic>P<</italic>0.01), the times of escape platform increased,and the contents of serum ACh,ChAT and hippocampal ACh,AchE,<italic>α</italic>7nAChR protein and <italic>α</italic>7nAChR mRNA increased (<italic>P<</italic>0.05). Conclusion:Huanglian Jiedutang can significantly improve the learning and memory ability of AD rats induced by A<italic>β</italic><sub>1-42</sub>,and its mechanism may be related to the improvement of cholinergic system damage and enhancement of cholinergic system function induced by A<italic>β</italic><sub>1-42</sub>.

RESUMEN

In the view of the defects of the commonly used moxibustion instruments and moxa heating instruments, such as the moxa ash cannot be removed automatically, the temperature of moxibustion and moxibustion smoke is difficult to be stabilized and adjusted, and the instruments are complex and expensive, a moxibustion device with separated moxibustion smoke and heat is designed. This device can automatically remove the moxa ash and keep it on the isolation net; the temperature of the moxibustion outlet is maintained at 43-48 ℃ (effective moxibustion temperature) for more than 40 minutes, and there is no visible moxa smoke; the temperature of the moxa smoke outlet is controlled between 28-75 ℃, and the effective discharge of moxa smoke can be realized without external power equipment. This device has the advantages of stable and controllable temperature of moxibustion outlet and moxa smoke outlet, automatic removal and collection of moxa ash, separation of moxa smoke without additional power, etc., which can be used in clinical and animal experiments for moxa heating, moxa smoke removal, etc.

RESUMEN

OBJECTIVE@#To explore the effects of electroacupuncture (EA) on skeletal muscle and blood glucose in rats with diabetic amyotrophy.@*METHODS@#Among 40 SD rats, 10 rats were randomly selected into the control group and received no treatment. The remaining 30 rats were treated with intraperitoneal injection of streptozotocin (STZ, 60 mg/kg) to establish diabetes mellitus (DM) model, and then the rats were treated with vascular ligation at right posterior limb to establish amyotrophy model. The rats with diabetic amyotrophy were randomly divided into a model group and an EA group, 10 rats in each group (10 rats were excluded due to unsuccessful model establishment and death). The rats in the EA group was treated with EA at right-side "Yishu (EX-B 3)" "Shenshu (BL 23)" "Zusanli (ST 36)" and "Sanyinjiao (SP 6)", disperse-dense wave, 2 Hz/ 15 Hz, 20 minutes each time, once a day for 3 weeks. Before and after EA treatment, the blood sample was collected from inner canthus and the "glucose oxidase-peroxidase" method was used to detect fasting blood glucose level; ELISA method was used to detect insulin content. At the end of the treatment, HE staining method was used to observe the morphology of ischemic skeletal muscle in the right hindlimb; the real-time PCR method was used to detect the mRNA expression of muscle atrophy F-box (MAFbx), muscle ring finger-1 (MuRF1) and forkhead box O3a (FOXO3a) in the ischemic skeletal muscle tissue of right hindlimb.@*RESULTS@#Before the treatment, the body mass in the model group and EA group was lower than that in the control group (<0.01); after the treatment, the body mass in the control group was increased, while the body mass in the model group and EA group was decreased (<0.01). Compared with the control group, the fasting blood glucose was significantly increased and insulin content was significantly decreased in the model group (<0.01); compared with the model group, the fasting blood glucose was significantly decreased and the insulin content was significantly increased in the EA group after treatment (<0.01). The muscle fibers of the model group were obviously broken, the number of the nuclei decreased, and the nuclei shrinked or even dissolved; the morphology of the muscle tissue of the EA group after intervention was improved compared with the model group. Compared with the control group, the cross-sectional area of ischemic skeletal muscle cells in the right hindlimb in the model group was decreased (<0.01); compared with the model group, the cross-sectional area of ischemic skeletal muscle cells in the right hindlimb was increased in EA group (<0.05). Compared with the control group, the levels of MAFbx, MuRF1 and FOXO3a mRNA in the right hindlimb ischemic skeletal muscle in the model group were increased significantly (<0.01, <0.05); compared with the model group, the levels of MAFbx, MuRF1 and FOXO3a mRNA in the EA group were decreased significantly (<0.05, <0.01).@*CONCLUSION@#EA may play a role in the treatment of diabetic amyotrophy by inducing FOXO3a to reduce the transcription of MAFbx and MuRF1.

RESUMEN

The threat of antibiotic resistant bacteria has called for alternative antimicrobial strategies that would mitigate the increase of classical resistance mechanism. Many bacteria employ quorum sensing (QS) to govern the production of virulence factors and formation of drug-resistant biofilms. Targeting the mechanism of QS has proven to be a functional alternative to conventional antibiotic control of infections. However, the presence of multiple QS systems in individual bacterial species poses a challenge to this approach. Quorum sensing inhibitors (QSI) and quorum quenching enzymes (QQE) have been both investigated for their QS interfering capabilities. Here, we first simulated the combination effect of QQE and QSI in blocking bacterial QS. The effect was next validated by experiments using AiiA as QQE and G1 as QSI on Pseudomonas aeruginosa LasR/I and RhlR/I QS circuits. Combination of QQE and QSI almost completely blocked the P. aeruginosa las and rhl QS systems. Our findings provide a potential chemical biology application strategy for bacterial QS disruption.

RESUMEN

The quantum entanglement is a new discovery of modern physics and has drawn a widely attention in the world. After learning the quantum entanglement, the authors have found that many characteristics of quantum are reflected in TCM, acupuncture theory and clinical practice. For example, the quantum entanglement phenomenon is mutually verified with the holism,doctrine, the theory of primary, secondary, root and knot in TCM, etc. It can be applied to interpret the clinical situations which is difficult to be explained in clinical practice, such as the instant effect of acupuncture, multi-point stimulation in one disorder and the points with specific effects. On the basis of the discovery above, the quantum entanglement theory achieved the mutual treatment among the relatives in acupuncture clinical practice and the therapeutic effects were significant. The results suggest that the coupling relationship in quantum entanglement presents between the diseases and the acupoints in the direct relative. The authors believe that the discovery in this study contributes to the exploration on the approaches to the acupuncture treatment in clinical practice and enrich the ideas on the disease prevention.

RESUMEN

Cathepsin K (CTSK) is considered a critical pharmaceutical target in the treatment of osteoporosis. CTSK exerts proteolytic activities against regulatory proteins besides its collagenase function, which may account for some of the adverse reactions when blocked by active site-directed inhibitors. Exosite inhibitors that can discriminate between the therapeutic collagenase and other biological activities of CTSK specifically inhibit the collagenase activity of CTSK without interfering with the other proteolytic activities of the protease. Active recombinant CTSK was expressed in Pichia pastoris, and purified by n-butyl sepharose and SP sepharose column chromatography. Herba Ecliptae is a common traditional Chinese medicine in the treatment of bone diseases. Collagenase assay and benzyloxycarbonyl-Phe-Arg-7-amido-4-methylcoumarin (Z-FR-MCA) substrate assay based on CTSK are applied to verify the exosite inhibitors. n-Butanol extract of Herba Ecliptae are the most active fraction and eclalbasaponin IX isolated from n-butanol fraction is the potential exosite inhibitor of CTSK.

RESUMEN

OBJECTIVES: The present study aimed to investigate the effects of guided imagery training on heart rate variability in individuals while performing spaceflight emergency tasks. MATERIALS AND METHODS: Twenty-one student subjects were recruited for the experiment and randomly divided into two groups: imagery group (n = 11) and control group (n = 10). The imagery group received instructor-guided imagery (session 1) and self-guided imagery training (session 2) consecutively, while the control group only received conventional training. Electrocardiograms of the subjects were recorded during their performance of nine spaceflight emergency tasks after imagery training. RESULTS: In both of the sessions, the root mean square of successive differences (RMSSD), the standard deviation of all normal NN (SDNN), the proportion of NN50 divided by the total number of NNs (PNN50), the very low frequency (VLF), the low frequency (LF), the high frequency (HF), and the total power (TP) in the imagery group were significantly higher than those in the control group. Moreover, LF/HF of the subjects after instructor-guided imagery training was lower than that after self-guided imagery training. CONCLUSIONS: Guided imagery was an effective regulator for HRV indices and could be a potential stress countermeasure in performing spaceflight tasks.

RESUMEN

To study the pharmacokinetic process of Danshensu in cerebal ischemia injury model rats and the correlation with its anti-cerebral ischemia effect. In this study, the middle cerebral artery occlusion (MCAO) model was established, in which all of the rats were intravenously injected of Danshensu at a single dose of 40 mg x kg(-1). The HPLC-DAD method was applied to determine the plasma concentration of Danshensu at different time points and draw the drug-time curve. Meanwhile, the superoxide dismutase (SOD) and the lactate dehydrogenase (LDH) activity were determined to draw the time-effect curve. The DAS 3.2. 6 software was used to process the data, analyze their correlation, compare the pharmacokinetic difference between model and normal rats after the administration of the same doses of Danshensu and the changes in pharmacodynamic indicators of model rats after the administration, and evaluate the effect of Danshensu in treating the cerebral ischemia disease. According to the results, the pharmacokinetic processes of Danshensu in the cerebral ischemia-reperfusion and normal rats were consistent to the two-compartment model. The main pharmacokinetic parameters were: t1/2alpha were (0.267 +/- 0.026), (0.148 +/- 0.020) h;t1/2beta were (1.226 +/- 0.032), (1.182 +/- 0.082) h; AUC0-infinity were (42.168 +/- 4.007), (26.881 +/- 1.625) mg x L(-1) x h. After the cerebral ischemia-reperfusion, the activity of SOD decreased and the activity of LDH increased. Danshensu could inhibit the decrease in the SOD activity and the increase in the LDH activity within a certain period of time. This indicated that Danshensu could stay longer in cerebral ischemia-reperfusion rats than in normal rats and eliminated more slowly, which reflected the rationality of Danshensu in the clinical treatment of cerebral ischemia diseases. Danshensu's effect against the cerebral ischemic injury may be related with its level in vivo. Its plasma concentration is positively related to the SOD activity and negatively related to the LDH activity.

RESUMEN

The paper is to evaluate the efficacy and safety of Shenmai injection for chronic heart failure, retrieving the Pubmed, CBM, CNKI, Wanfang database and VIP database to comprehensively collect all types research report of Shenmai injection for chronic heart failure (CHF). Particularly wishing to point out, randomized controlled trials are include for the evaluation of effectiveness, which are statistically analyzed and evaluated by Rev-Man 5. 2. The current studies show that the improvement rate of NYHA classification of cardiac function of CHF patients and their related indexes figure such as LVEF, SV, CO, BNP, 6 min walking test value are all improved by the combination of Shenmai injection and foundation treatment. However, HR is almost no improvement. Meanwhile, serious ADR/AE of Shenmai injection for CHF isn't appear.
