Objective To study the curative effect of traditional chinese medicine combined with noninvasive ventilation on respiratory failure in patients with acute exacerbation of chronic obstructive pulmonary disease.MethodsThe patients were divided into experimental group (n=37) and control group (n=37).The experimental group was treated with traditional chinese medicine combined with noninvasive ventilation.The control group was treated with noninvasive ventilation method.The heart rate, blood gas analysis index, ventilation index and complication were compared between the two groups before and after treatment.ResultsAfter treatment, the levels of PaO2 in the two groups were not significantly different.The heart rate and PaCO2 of the experimental group were significantly lower than those of the control group, while the pH value and SaO2 were significantly higher than those in the control group (P< 0.05), and the total incidence of complications was 21.62%, which was significantly lower than that of the control group (64.86%, P<0.05).The time of infection control window, the highest PEEP and the time of mechanical ventilation were significantly shorter than those of the control group (P< 0.05).ConclusionThe treatment of patients with acute exacerbation of chronic obstructive pulmonary disease(COPD) combined with noninvasive ventilation therapy can significantly improve the heart rate and blood gas analysis indexes, and optimize the noninvasive ventilation efficiency, control lung infection as soon as possible, shorten the time of noninvasive ventilation and reduce the side effects that noninvasive ventilation brought about.

The percent of N and C composition in spores or sporocarps of different species of two genera of VA mycorrhizal fungi—Gloraus and Sclerocystis were analysed. It was found that culture period effects the percent of N,C and their ratio, although the influences of host and origin of strain of fungi on those appeared to be low. N,C percentage and their ratio in spores or sporocarps were variable among fungal species of a same genus, but difference between two genera was significantly. This technology may serve as a supplementary indicator for classification and identification of VA mycorrhizal fungi.

Objective To clarify the position,figure and connections with adjacencies in the pallial thickening(Pth),and provide essential parameters for its function study. Methods The coronal serial sections of 60?m thickness in gekko gecko brain were made by cryo-microtome,and Nissl staining was used.Pictures were taken in each coronal section containing the Pth and the size of Pth in each section was measured.One of them was chosen for the three-dimensional reconstruction.3D MAX was used as the tool software to rebuild the nucleus. Results 1.The Pth was located in the rostral part of the telencephalon,the lateral part of anterior dorsal ventricular ridge,the medial part of the lateral cortex and the ventral part of the dorsal cortex.The length of Pth from the rostral to the caudal end was(912.67?110.96)?m(n=10),the cubage of Pth was about(0.1430?0.0414)?m~3(n=10).2.The Pth could be divided into four segments,the anterior,the middle,the posterior and the terminal segments from the rostral to the caudal end.In the posterior segment,its dorsoventral axis was the longest,and could be divided into two parts: the dorsal and the ventral parts.The boundary of the two parts was clear.Conclusion The Pth is a long,narrow and flat structure;its rostrocaudal axis is longer than its dorsoventral axis,and its dorsal edge is smoother than its ventral edge.In the Pth,its caudal region is larger than its rostral region,and the posterior segment in the caudal region is divided into the dorsal and the ventral cell populations.

Objective: To investigate the effect of compound methoxyphenamine in the treatment of cough after infection. Methods: From September 2016 to September 2017, 94 patients with infection after cough in the Traditional Chinese Medicine Hospital of Jinhua were selected in the research and randomly divided into two groups according to the digital table, with 47 cases in each group.The observation group was given compound methoxyphenamine, the control group was given azithromycin treatment.The treatment effect was compared between the two groups. Results: Before treatment, the cough scores of the observation group and the control group were (1.4±0.7) points and (1.5±0.5)points, respectively.After treatment for one course, the cough scores of the observation group and the control group were (0.3±0.1)points and (0.8±0.2)points, respectively, the improvement of cough in the observation group was obviously better than that of the control group (t=5.024, P<0.05). After treatment, the total effective rates of the observation group and control group were 95.7%(45/47) and 83.0%(39/47), respectively, the treatment effect of the observation group was obviously better than that of the control group (χ²=11.265, P<0.05). After treatment, the incidence rates of adverse reaction of the observation group and the control group were 4.3%(2/47) and 21.3%(10/47), respectively, the incidence rate of adverse reaction of the observation group was lower than that of the control group (χ²=22.452, P<0.05). Conclusion The application of compound methoxyphenamine in patients with infection after cough can alleviate symptoms of patients with cough, reduce adverse reactions, has significant effect, so this kind of treatment method is worthy of popularizing in clinical use.

Rutin,a flavonoid found in fruits and vegetables,is a potential anticancer compound with strong anti-cancer activity.Therefore,electrochemical sensor was developed for the detection of rutin.In this study,CoWO4 nanosheets were synthesized via a hydrothermal method,and porous carbon(PC)was prepared via high-temperature pyrolysis.Successful preparation of the materials was confirmed,and character-ization was performed by transmission electron microscopy,scanning electron microscopy,and X-ray photoelectron spectroscopy.A mixture of PC and CoWO4 nanosheets was used as an electrode modifier to fabricate the electrochemical sensor for the electrochemical determination of rutin.The 3D CoWO4 nanosheets exhibited high electrocatalytic activity and good stability.PC has a high surface-to-volume ratio and superior conductivity.Moreover,the hydrophobicity of PC allows large amounts of rutin to be adsorbed,thereby increasing the concentration of rutin at the electrode surface.Owing to the syn-ergistic effect of the 3D CoWO4 nanosheets and PC,the developed electrochemical sensor was employed to quantitively determine rutin with high stability and sensitivity.The sensor showed a good linear range(5-5000 ng/mL)with a detection limit of O.45 ng/mL.The developed sensor was successfully applied to the determination of rutin in crushed tablets and human serum samples.

【Objective】 To investigate whether the psychological counseling nursing could alleviate psychological stress and reduce the incidence of adverse events in patients receiving advanced autologous apheresis (AAA) treatment. 【Methods】 A total of 253 patients who underwent AAA treatment in our department from September 2019 to February 2020 were studied and randomly divided into the observation group (n=127) and the control group (n=126). Other than the routine nursing, the patients in the observation group also received psychological counseling nursing. The scores of self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were used to compare the psychological stress state and the incidence of adverse events between two groups, and the nursing satisfaction was evaluated by NSNS scores. 【Results】 The SAS and SDS scores in the observation group( after receiving counseling nursing as the psychological intervention) were 30.03±5.06 and 33.59±4.49, respectively, significantly lower than those in the control group (43.55±3.68 and 42.18±4.22, respectively) (P<0.05). The incidences of adverse events (convulsions not included) in the observation group and the control group were 11.8%(15/127) vs 26.2%(33/126) (palpitation and shortness of breath), 6.3%(8/127) vs 16.7%(21/126) (sweating), 8.7%(11/127) vs 23.8%(30/126) (dizziness and numbness in mouth), and 5.5%(7/127) vs 19.8%(30/126) (nausea), respectively (P<0.05). The total nursing satisfaction rate of the observation group was 98.4% (125/127), which was significantly higher than that of the control group (92.9%, 117/126) (P<0.05). 【Conclusion】 The psychological counseling nursing can effectively relieve the psychological stress of patients receiving AAA treatment and reduce the incidence of adverse events.
