Effects of biocontrol strain BZJN1 and streptoprofen on physicochemical properties and bacteria structure of rhizosphere soil of Atractylodes macrocephala / 中国中药杂志

Soil microorganisms are one of the important biological indictors of soil quality and can reflct the comprehensive ecological environment characteristics of the soil. The research of soil microbial diversity is the key to know the ecological functions and balance with soil. In this paper, high-throughput sequencing on PCR-amplified 16 S rRNA gene V3-V4 fragments was used to determine the bacterial diversity in rhizosphere soil of A. macrocephala under the treatment with BZJN1 or streptoprofen. The results showed that there were no significant differences of the bacteria in A. macrocephala rhizosphere soil of the streptoprofen treatment group and the biocontrol BZJN1 treatment group. All the soil bacteria was classified into 25 categories,67 classes, 108 orders, 167 families and 271 generas, except some unidentified bacteria. Proteobacteria(30.7%-34.8%) was the dominant phylum, of which Alphaproteobacteria(16.8%-18.5%) was the dominant subgroup. Compared with the control group, the relative abundance of multiple phylums bacteria in the rhizosphere soil of A. macrocephala was significantly changed in the streptoprofen treatment group and the biocontrol BZJN1 treatment group. In addition, RDA analysis showed that there was connection with different environmental factors and microbial communities. The abundance of the three genera in the rhizosphere soil of A. macrocephala was significantly positively correlated with Invertase, Urease and AP. PICRUSt function prediction results showed that BZNJ1 could enhance some bacterial functions and promote the plant growth. Biocontrol is a new type of green and safety control pest method. BZNJ1 significantly enhances some bacterial functions on the basis of effectively preventing root rot of A. macrocephala and promoting plant growth, and has no significant effect on the soil bacterial community structure. All the results can provide theoretical support for popularization of BZNJ1.

Meta-analysis of the Clinical Efficacy of Contralateral Needling in Treating Acute-stage Peripheral Facial Paralysis / 上海针灸杂志

Objective To compare the clinical efficacy between contralateral needling and homolateral (the affected side) needling in treating acute-stage peripheral facial paralysis by using systematic evaluation. Method By computer and manual retrieval, literatures about clinical trials on contralateral needling in treating acute-stage peripheral facial paralysis published before March of 2017 were collected from China National Knowledge Infrastructure (CNKI), WanFang database, Vip database, China Biology Medicine disc (CBMdisc), Pubmed, Web of Science, EMbase and The Cochrane Library. By adopting the Cochrane systematic evaluation, the collected data underwent meta-analysis by using RevMen 5.3 software. Result A total of 276 articles were retrieved and 11 articles were finally recruited, including 761 patients with acute-stage facial paralysis, 394 cases treated by contralateral needling and 367 by homolateral needling. The meta-analysis showed that contralateral needling produced more significant effective rate and recovery rate than homolateral needling [effective rate: RR=1.06, 95％CI(1.01,1.11), Z=2.32, P=0.02; recovery rate:RR=1.53, 95％CI(1.31,1.78), Z=5.42, P<0.01]. Moreover, contralateral needling produced a better effect in improving facial nerve function, showing an advantage in ameliorating facial movement [HB: WMD=0.26, 95％CI(0.04,0.48), Z=2.34, P=0.02; FDIP: WMD=3.77, 95％CI(1.53,6.01), Z=3.30, P<0.01]. Conclusion Contralateral needling is worth applying in treating acute-stage peripheral facial paralysis. However, due to the small amount and unsatisfactoryquality of the recruited literatures in this systematic evaluation, multiple-centered randomized trials with high quality and large sample size are expected for further verification.

Hyperoxygenated solution for improved oxygen supply in patients undergoing lung lavage for pulmonary alveolar proteinosis / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>At present, the most effective treatment for pulmonary alveolar proteinosis (PAP) remains whole-lung lavage in spite of the usually accompanying severe hypoxemia, which is expected to be prevented by hyperoxygenated solution improving oxygen supply during lavage. In this study, the efficacy and safety of the effect of hyperoxygenated solution were evaluated.</p><p><b>METHODS</b>Five patients underwent whole-lung lavage over a 28-month period. Each lung was lavaged with hyperoxygenated (HO) and normal saline solution (plain lactated Ringer's solution, NO) randomly and alternatively until the reclaimed fluid was clear. Random number was generated by computer before every cycle of lavage. If the number was odd, the patient was assigned to receive a lavage cycle with hyperoxygenated solution (HO group, n = 109); if the number was even, normal saline solution was used (NO group, n = 115). Data of saturation of peripheral oxygen (SPO(2)), mean arterial pressure (MAP), central venous pressure (CVP), heart rate (HR) and end-tidal carbon dioxide tension (P(ET)CO(2)) were taken down at 0, 30, 60, 90, 120, 150, 180, 210 and 240 seconds from the beginning of the instillation of solution, and frequency and volume of unilateral lung lavage were also recorded. Time interval between the left and the right lung lavage was 1 week.</p><p><b>RESULTS</b>No patient was withdrawn from the study due to low SPO(2) or leakage. Oxygen pressure was (730.21 +/- 7.43) mmHg in the hyperoxygenated solution against (175.73 +/- 5.92) mmHg in the normal saline solution (P < 0.01). Compared with baseline, SPO(2) increased significantly as the instillation of solution began (P < 0.01), leveled for about 30 seconds (P > 0.05), and then decreased significantly to the lowest at the time of drainage (compared with 120 seconds or peak, P < 0.01). SPO2 was higher in HO group than in NO group (P < 0.01). There were no significant differences in MAP, HR, CVP and P(ET)CO(2) between HO group and NO group (P > 0.05) and also among different time points (P > 0.05).</p><p><b>CONCLUSION</b>During the lung lavage for pulmonary alveolar proteinosis, hyperoxygenated solution could significantly improve oxygen supply in comparison with normal saline solution without obvious side effects.</p>

Effects of gingko biloba extract on glutamate-induced Ca2+i changes in cultured cortical astrocytes after hypoxia/reoxygenation, H2O2 or L-glutamate injury / 药学学报

<p><b>AIM</b>To investigate glutamate-induced [Ca2+]i changes in cultured rat neonatal cortical astrocytes after hypoxia/reoxygenation, H2O2 or high concentration of L-glutamate injury. In the meantime, the effects of Gingko biloba extract (GbE) were examined.</p><p><b>METHODS</b>[Ca2+]i changes in astrocytes were monitored by laser scanning confocal microscopy with the Ca2+ sensitive fluorescent probe fluo-3.</p><p><b>RESULTS</b>After astrocytes were impaired by hypoxia/reoxygenation, H2O2 (50 micromol x L(-1)) or L-glutamate (0.25 mmol x L(-)), the exogenous glutamate (27 micromol x L(-1)) could not induce increase of [Ca2+]i, but decrease by (3.3 +/- 1.6)%, (81 +/- 11)% and (81 +/- 7)%, respectively. Pretreatment with GbE (10 mg x L(-1)) could not improve injured astrocytic glutamate response. But after pretreatment with GbE (100 mg x L(-1)), glutamate-induced [Ca2+]i elevation of astrocytes after hypoxia/reoxygenation, H2O2 or high concentration of L-glutamate injury were (135 +/- 98)%, (117 +/- 93)% and (89 +/- 36)%, respectively. Nimodipine (1.6 mg x L(-1)) could also reverse the abnormal response of astrocytes after different injury.</p><p><b>CONCLUSION</b>Hypoxia/reoxygenation, H2O2 and high concentration of L-glutamate impaired astrocytes' response to exogenous L-glutamate, and then bidirectional communication between astrocytes and neurons could not take place. GbE could improve the abnormal responses and maintain the normal function of astroglical network. These effects support that GbE has potential beneficial actions against brain injury.</p>
