Quality Evaluation of Atractylodis Macrocephalae Rhizoma in Different Production Methods Based on Traditional Traits / 中国实验方剂学杂志

ObjectiveBased on the experience of traditional quality evaluation， the quality of Atractylodis Macrocephalae Rhizoma（AMR） with different production methods such as direct seeding， transplanting after seedling raising， topping and non-topping， and difference in growth years was compared. MethodVernier caliper was used to measure the trait data of AMR in different production methods. Paraffin sections of AMR with different production methods were made by saffron solid green staining， and the microstructure was observed. The contents of water-soluble and alcohol-soluble extracts in AMR with different production methods were determined according to the 2020 edition of Chinese Pharmacopoeia. The content of water-soluble total polysaccharides in AMR with different production methods was detected by sulfuric acid-anthrone method. Fiber analyzer was used to detect the content of fiber components in AMR with different production methods. The contents of monosaccharides， oligosaccharides and some secondary metabolites in AMR with different production methods were detected by ultra performance liquid chromatography（UPLC）， and the differences of chemical components were compared by multivariate statistical analysis methods such as principal component analysis（PCA） and partial least squares-discriminant analysis（PLS-DA）. ResultIn terms of traits， the 3-year-old AMR with direct seeding and without topping was close to the high-quality AMR with "phoenix-head and crane-neck， strong sweetness and clear aroma" recorded in ancient materia medica， followed by the 3-year-old AMR with topping after transplanting， while the 2-year-old AMR with topping after transplanting with high market circulation rate was generally fat and strong with mild odor. In the microscopic aspect， the arrangement of xylem vessels and fiber bundles in the 3-year-old samples formed two obvious rings. Compared with the 2-year-old samples cultivated in Bozhou and Zhejiang， the 3-year-old samples without topping after transplanting had more wood fibers. In terms of chemical composition， the contents of 70% ethanol extract， fructose， glucose， sucrose， 1-kestose， atractylenolide Ⅰ， chlorogenic acid， neochlorogenic acid， cryptochlorogenic acid and other components in 3-year-old AMR with direct seeding and without topping were significantly higher than those in the other three samples（P<0.05）. The contents of cellulose， 70% ethanol extract， sucrose， atractylenolide Ⅰ， atractylone and other components in 3-year-old AMR with topping after transplanting were significantly higher than those in the 2-year-old AMR with high market circulation rate（P<0.05）， while the contents of water-soluble extract and water-soluble total polysaccharides in 2-year-old samples with topping after transplanting were significantly higher than those in the 3-year-old AMR with topping after transplanting， direct seeding and without topping（P<0.05）. ConclusionUnder the current mainstream production mode， too much manual intervention makes AMR heavily enriched in polysaccharides and increased the yield， but the accumulation of sweet substances， fragrant substances and fiber substances is insufficient， which affects its quality. The current quality standard of AMR has some shortcomings in guiding the high quality production of it， it is suggested to revise the quality standard of AMR， supplement the quantitative analysis of secondary metabolites， and strengthen the production of imitation wild AMR.

Effects of Shenmai injection combined with enteral nutrition on immune function of patients with severe cardiac insufficiency / 中国中西医结合急救杂志

Objective To observe the effect of Shenmai injection combined with enteral nutrition (EN) on immune function in patients with severe cardiac insufficiency. Methods Fifty-seven patients with severe cardiac insufficiency admitted to the Department of Critical Care Medicine of Taizhou Hospital of Zhejiang Province from June 2015 to June 2018 were divided into an EN group (31 cases) and an EN group combined with Shenmai injection group (26 cases). The EN group was given EN on the basis of routine western medicine treatment, while in the EN combined with Shenmai injection group was treated additionally by intravenous drip of Shenmai injection 100 mL/d on the basis of above EN group treatment. The efficacies of the two groups were evaluated after consecutive 7-day treatment in the two groups. The changes in levels of subsets of T-lymphocytes (CD3+, CD4+, CD8+, CD4+/CD8+) and immunosuppressive cells CD14+ monocyte human leukocyte antigen DR (HLA-DR) were observed before and after treatment. Results After treatment, the levels of T-cell subsets CD3+, CD4+, CD4+/CD8+ and CD14+ monocytes HLA-DR in the peripheral blood of the two groups were significantly higher than those before treatment [CD3+: EN group was 0.539±0.126 vs. 0.379±0.093,Shenmai injection group was 0.652±0.185 vs. 0.393±0.091; CD4+: EN group was 0.402±0.121 vs. 0.275±0.066,Shenmai injection group was 0.524±0.168 vs. 0.281±0.077; CD4+/CD8+:EN group was 1.83±0.70 vs. 1.11±0.70,Shenmai injection group was 2.81±0.91 vs. 1.19±0.58; CD14+HLA-DR:EN group was (43.3±7.1)% vs. (35.4±5.7)%,Shenmai injection group was (54.9±6.2)% vs. (36.1±8.3)%]; After treatment, CD8+ in EN group decreased (0.223±0.052 vs. 0.253±0.081), while CD8+ in shenmai injection group increased (0.288±0.051 vs. 0.259±0.078), and the increase degrees of the above-mentioned indexes in EN combined with Shenmai injection group were more obvious than those in the EN group after treatment [CD3+: 0.652±0.185 vs. 0.539±0.126, CD4+: 0.524±0.168 vs. 0.402±0.121, CD8+: 0.288±0.051 vs. 0.223±0.052, CD4+/CD8+: 2.81±0.91 vs. 1.83±0.70, CD14+HLA-DR: (54.9±6.2)%, (43.3±7.1)%, all P < 0.05]. Conclusion The combined use of Shenmai injection and early EN can improve the immune function of T-lymphocytes in patients with severe cardiac insufficiency. The mechanism may be related to the enhancement of the activation of T lymphocytes and promotion of the CD14+ monocytes increase and immune function.

Characteristics analysis of AIDS complicated with severe pneumonia / 中华实验和临床病毒学杂志

Objective@#To investigate the characteristics and pathogenic characteristics of acquired immunodeficiency syndrome (AIDS) complicated with severe pneumonia.@*Methods@#The clinical data of patients with AIDS complicated with severe pneumonia who were hospitalized and treated in the First People′s Hospital of Linhai City from January 2016 to January 2018 were collected. The laboratory test results, imaging findings, distribution of pathogens, mixed infections of pathogens, treatment and outcomes were statistically analyzed. The influencing factors of the prognosis were tested by Fisher′s exact test, and Logsitic regression analysis was used for multivariate analysis.@*Results@#Among the 42 patients, the majority were male patients(90.48%), and most of them were 21 to 50 years old(78.57%), and the onset involved multiple systems. The CD4+ T lymphocyte count was less than 200/mm2 (100.0%) in the 42 patients, including 69.05% less than 50/mm2 and 73.81% of patients had albumin levels lower than 25 g/L. Chest CT showed multiple or diffuse distribution of increased density and ground glass opacity. Various strains of microorganisms were successfully isolated from 29 cases (69.05%), a total of 76 strains. The top three of pathogen spectrum were fungi (60.53%, 46/76), Gram negative bacteria (15.79%, 12/76) and Gram positive bacteria (10.53%, 8/76); 92.86% of the patients were infected with 2 or more kinds of pathogenic bacteria. In the 42 patients, 17 cases (40.48%) survived and 25 cases (59.52%) died. Univariate analysis showed that CD4+ T lymphocyte count<50 /mm2, the albumin level<25 g/L and mechanical ventilation were related to the prognosis of the disease. Multivariate Logstic regression analysis showed that the albumin level <25 g/L and mechanical ventilation were independent risk factors affecting the prognosis of the disease.@*Conclusions@#Fungal infection is the most common infection in patients with AIDS complicated with severe pneumonia, and 92.86% of them are accompanied by mixed infections. Low albumin level and mechanical ventilation are important risk factors influencing the prognosis.

A study on the coordinated development strategy of medicine and health, medical security and social economy in China / 中华医院管理杂志

The paper describes the short and medium term (within 2 to 5 years) priorities that any region in China right now faces in working out and implementing its regional health planning, viz. the coordinated development strategy of medicine and health, medical security and social economy. The authors hold that to achieve the coordinated growth of the health cause and society, it is imperative to overcome in the short run logically related obstacles in four aspects: ineffective solution to the apparent problems followed with interest by both the social and health sectors and lack of effective operating conditions accompanying medical insurance reform, both resulting in the lack of a driving force in the reform within hospitals; difficulty in achieving breakthroughts in the development of the health cause; and the probability of a regional health planning becoming a mere formality because of the above factors. In addition, the fact that reform of medical and health institutions in their setup and ownership of property rights lags behind macroscopic social economic reform obscures the explanation of and solution to the above problems. Based on the research results, the paper sets forth the priorities in short and medium term planning.
