RESUMEN

OBJECTIVE: To understand research advances and frontiers of acupuncture regulation on the autonomic nervous system (ANS) over the past decade through a bibliometric analysis. METHODS: Publications related to acupuncture regulation on the ANS were retrieved from the Web of Science Core Collection (WoSCC) database. CiteSpace software was used to analyze the datasets and generate knowledge maps. RESULTS: A total of 445 relevant publications published between 2013 and 2022 were included in this bibliometric analysis. The number of annual publications fluctuated from 2013 to 2016 but increased gradually from 2016 to 2022. China produced the highest number of publications, while the USA established the most extensive cooperation relationships. China Academy of Chinese Medical Science was the most productive institution. Chen Jiande D.Z. was the most prolific author and Rong Peijing holds the most extensive cooperation network. Han Jisheng was the most co-cited author. Relevant research involved mechanism exploration and clinical efficacy research, and "anti-inflammatory effect" was the most active research topic, especially cholinergic anti-inflammatory mechanisms. The most cited references mainly focused on inflammation. Gastrointestinal and cardiovascular disorders were the most active medical conditions studied in this field. CONCLUSIONS: Research related to acupuncture regulation on the ANS mainly focused on anti-inflammation, and regulating gastrointestinal and cardiovascular function over the past decade. However, the mechanisms of the autonomic effects of acupuncture need further investigation. High-quality clinical studies are required to determine the optimal parameters of acupuncture for clinical application.

RESUMEN

OBJECTIVE@#To explore the mechanism of electroacupuncture (EA) in promoting recovery of the facial function with the involvement of autophagy, glial cell line-derived neurotrophic factor (GDNF), and phosphatidylinositol-3-kinase (PI3K)/mammalian target of rapamycin (mTOR) signaling pathway.@*METHODS@#Seventy-two male Sprague-Dawley rats were randomly allocated into the control, sham-operated, facial nerve injury (FNI), EA, EA+3-methyladenine (3-MA), and EA+GDNF antagonist groups using a random number table, with 12 rats in each group. An FNI rat model was established with facial nerve crushing method. EA intervention was conducted at Dicang (ST 4), Jiache (ST 6), Yifeng (SJ 17), and Hegu (LI 4) acupoints for 2 weeks. The Simone's 10-Point Scale was utilized to monitor the recovery of facial function. The histopathological evaluation of facial nerves was performed using hematoxylin-eosin (HE) staining. The levels of Beclin-1, light chain 3 (LC3), and P62 were detected by immunohistochemistry (IHC), immunofluorescence, and reverse transcription-polymerase chain reaction, respectively. Additionally, IHC was also used to detect the levels of GDNF, Rai, PI3K, and mTOR.@*RESULTS@#The facial functional scores were significantly increased in the EA group than the FNI group (P<0.05 or P<0.01). HE staining showed nerve axons and myelin sheaths, which were destroyed immediately after the injury, were recovered with EA treatment. The expressions of Beclin-1 and LC3 were significantly elevated and the expression of P62 was markedly reduced in FNI rats (P<0.01); however, EA treatment reversed these abnormal changes (P<0.01). Meanwhile, EA stimulation significantly increased the levels of GDNF, Rai, PI3K, and mTOR (P<0.01). After exogenous administration with autophagy inhibitor 3-MA or GDNF antagonist, the repair effect of EA on facial function was attenuated (P<0.05 or P<0.01).@*CONCLUSIONS@#EA could promote the recovery of facial function and repair the facial nerve damages in a rat model of FNI. EA may exert this neuroreparative effect through mediating the release of GDNF, activating the PI3K/mTOR signaling pathway, and further regulating the autophagy of facial nerves.

RESUMEN

Moslae Herba is a commonly used aromatic Chinese medicinal with volatile oil as the main effective component and exhibits broad-spectrum antibacterial and antiviral effects. However, the irritation and instability of Moslae Herba volatile oil necessitate the preparation into a specific dosage form. In this study, the steam distillation method was employed to extract the Moslae Herba volatile oil. The content of thymol and carvacrol in Moslae Herba volatile oil was determined by HPLC as(0.111 9±0.001 0) and(0.235 4±0.004 7) mg·mL~(-1), respectively. Pseudo-ternary phase diagrams and surfactants compounding were applied in the selection of the optimal excipients(surfactant and cosurfactant). On this basis, a nanoemulsion was prepared from the Moslae Herba volatile oil and then loaded into pressure vessels to get sprays, whose stability and antibacterial activity were evaluated afterward. With clarity, viscosity, smell and body feeling as comprehensive indexes, the optimal formulation of the Moslae Herba volatile oil nanoemulsion was determined as follows: Moslae Herba volatile oil∶peppermint oil∶cremophor EL∶absolute ethanol∶distilled water 7.78∶1.58∶19.26∶6.15∶65.23. The as-prepared nanoemulsion was a light yellow transparent liquid, with Tyndall effect shown under the irradiation of parallel light. It has the pH of 5.50, conductivity of 125.9 μS·cm~(-1), average particle size of 15.45 nm, polydispersity index(PDI) of 0.156, and Zeta potential of-17.9 mV. Under a transmission electron microscope, the Moslae Herba volatile oil nanoemulsion was presented as regular spheres without adhesion and agglomeration. Stability test revealed that the Moslae Herba volatile oil nanoemulsion was stable at 4-55 ℃, which was free from demulsification and stratification within 30 days. After the centrifugation at 12 000 r·min~(-1) for 30 min, there was no stratification either. The nanoemulsion had good inhibitory effects on Escherichia coli, Staphylococcus aureus and resistant S. aureus strains, with the minimum inhibitory concentrations of 0.39, 3.12 and 1.56 mg·mL~(-1), respectively. The above results demonstrated that the nanoemulsion was prepared feasibly and showed stable physical and chemical properties and good antibacterial effects. This study provides a practicable technical solution for the development of anti-epidemic and anti-infection products from Moslae Herba volatile oil.

RESUMEN

OBJECTIVE: To investigate the molecular and functional changes in L-type Ca2+ channel of hypertrophied cardiomyocytes in neonatal rats induced by angiotensin II (Ang II). METHODS: The in vitro model of cardiomyocyte hypertrophy was established in cultured cardiomyocytes from neonatal rats. Whole cell patch clamp was used to measure the L-type Ca2+ currents. Semi-quantitative RT-PCR was used to determine the mRNA expression of L-type Ca2+ channel alpha1C subunits. RESULTS: In the hypertrophied cardiomyocytes induced by Ang II, I(Ca, L) densities were increased, whereas the features of I(Ca,L) activation, inactivation or recovery from inactivation were not affected. Meanwhile, Ang II increased the mRNA expression of L-type Ca2+ channel alpha1C subunits in cardiomyocytes. All these actions of Ang II could be blocked by the angiotensin II 1 type receptor blocker losartan. CONCLUSION: During cardiomyocyte hypertrophy induced by Ang II, there are significant changes in the molecule and function of L-type Ca2+ channels, which are mediated by the angiotensin II 1 type receptor.

RESUMEN

Endothelin-3 (ET-3) is aberrantly expressed in both metastatic melanoma tissues and cultured melanoma cells. Our previous work showed that ET-3 could promote survival of metastatic melanoma cells via its altered expression. In this study, we investigated the mechanisms responsible for these gene-induced phenotypes in melanoma cells. An ET-3 gene sequence-specific shRNA vector pLVTHM-ET3-RNAi was constructed and transfected into human malignant melanoma cells A375 and MMRU, and the resultant molecular events and cellular changes were examined. As compared with the empty-vector group, cell proliferation was slowed down, and the growth inhibition rates were 38.9% in A375 cells and 38.4% in MMRU cells after transfection. In addition, cell invasion capability was also inhibited, with a reduction of 62.2% in A375 cells and 54.3% in MMRU cells. The percentage of apoptotic cells was found to increase. Meanwhile, in both cell lines, secreted protein acidic and rich in cysteine (SPARC) levels were down-regulated together with inhibition of its upstream signaling molecule, NF-κB. Thus, the current results suggested that down-regulated expression of ET3 attenuates the malignant behaviors of human melanoma cells partially by decreasing the expression of SPARC and NF-κB.

RESUMEN

Two short interfering RNAs (siRNA-RdRp1286, siRNA-RdRp1441) and one short interfering RNA (siRNA-OCP117), targeted to the RNA dependent RNA polymerase (RdRp) gene and outer capsid protein (OCP) gene of Grass carp reovirus (GCRV) respectively, were chemically synthesized and transfected into the CIK cells by lipofectamine 2000. 6 hours after transfection, the transfected CIK cells were challenged with GCRV. The culture media were collected at 48h post challenge and the virus was titrated in microculture system to evaluate the inhibition effect on GCRV replication mediated by siRNAs. Referring to the mRNA level of housekeeping gene beta-actin, RT-PCR was applied to detect the level of GCRV mRNA in transfected and challenged CIK cells. The results showed that the viral titer (lgTCID50/0. 1mL) in siRNA-RdRp1286, siRNA-RdRp1441 and siRNA-OCP117 transfected CIK cells were 4.41 +/- 0.16, 3.83 +/- 0.44 and 1.94 +/- 0.42 respectively, which were significantly lower than that in virus infection positive control (7.92 +/- 0.52) (P < 0.01). No significant change in viral titer was observed in the group transfected with siRNA negative control after challenged with GCRV (7.50 +/- 0.17, P > 0.05). Compared with the mRNA transcriptional level of beta-actin gene in virus infection positive control, the mRNA levels of GCRV in siRNA-RdRpl 286, siRNA-RdRp1 441 and siRNA-OCP117 transfected CIK cells were reduced significantly and the inhibition rate reached to (82.08 +/- 2.15)%, (89.19 +/- 1.14).% and (92.62 +/- 0.17)%, respectively. The mRNA level of GCRV in the siRNA negative control group had no noticeable change (P > 0 05).

RESUMEN

By using cell culture and virus infection methods, a new reovirus had been isolated from channel catfish (Ictalurus punctatus) suffered with severe hemorrhage and had been identified as channel catfish reovirus (CCRV) after artificial infection in fish, electron microscopy observation, physical-chemical tests, genomic SDS-PAGE analysis and sequencing. In artificial infection test, the typical symptoms of channel catfish hemorrhage as naturally occurred could be reproduced. The isolated virus could cause typical cytopathic effect in CCO and CCK cell lines. Electron microscopy observation of ultra-thin section samples of CCRV infected CCO and CCK cells revealed that the virus replicated in cytoplasm, arrayed in crystalline, and had a non-enveloped double capsid with a diameter of 60-70 nm. Frozen-thawed, 56 degrees C 1 h, chloroform and ether had no significant effects on CCRV titer, 65 degrees C 1 h could significantly inactivated the viral infectivity. The CCRV genome SDS-PAGE analysis and nuclease sensitivity test showed that the virus genome was the same as that of viruses in Aquareovirudae and consisted of 11 segments of dsRNA assigned into three classes L1, L2, L3; M1, M2, M3 and S1, S2, S3, S4, S5 with a range of size from 0.9 to 4.4 kb. The Cloning and sequencing of the CCRV S4 segment indicated the nucleic acid number of CCRV S4 was 909 bp in length, which was exactly the same as that of GCRV S4 (AF403396) and GSRV S4 (AF403407) segments. The BLAST of CCRV S4 sequence in NCBI GenBank showed that it had a 99% and 90% similarity in sequence to the GCRV S4 and GSRV S4 segments, respectively.

RESUMEN

<p><b>OBJECTIVE</b>To investigate the protective effect of recombinant human N-terminal lipopolysaccharide binding protein in mice challenged with LPS.</p><p><b>METHODS</b>Seventy male Kunming mice were randomly divided into 3 groups, i.e. LPS challenge (Injection of LPS into abdominal cavity, n = 21); tLBP protection (Injection of LPS and tLBP into abdominal cavity, n = 21) and control (Injection of normal saline into abdominal cavity, n = 8) groups. The blood samples and tissue samples of the liver and lungs were harvested on 15 and 30 minutes and 1, 3, 6, 12 and 24 hours after the injection. The serum contents of ALT and TNF-alpha were determined by biochemical velocity analysis and RIA method, respectively. The pathomorphological changes in the liver and pulmonary tissue were examined under light microscope (LM). The mortality rate of ten mice each was observed within 24 hours after the injection of tLBP + 400 ng LPS or 400ng LPS.</p><p><b>RESULTS</b>The ALT content of tLBP group reached the peak level at 12 post-injection hour (PIH) (41.00 +/- 4.58), but it was significantly lower than that in LPS group in which it peaked at 6PIH (99.50 +/- 62.63) (P < 0.01). The TNF-alpha content in tLBP and LPS group was lower than that in LPS group, and both reached the peak level at 3 PIH (35.96 +/- 7.33). Compared with those in LPS, injury to hepatocytes in tLBP group was obviously milder without scattered necrosis. The pulmonary congestion in tLBP group was abated, and the inflammatory exudation in the alveoli was evidently less than that in LPS group. There were 9 out of 10 mice died in the LPS challenge group, while only 3 out of 10 mice died during 24 hours after LPS injection in tLBP protection group.</p><p><b>CONCLUSION</b>Preliminary results indicated that recombinant human tLBP might possess biological activity with a potential protection effect in LPS challenged mice.</p>
