Although echinocandins,a new generation of antifungal drugs,shows good fungicidal activity against distinct species of Candida,with the extending usage,the activity of echinocandins is gradually to decline,which is caused by different resistance mechanisms.Also,a number of factors may influence its results of susceptibility in vitro (e.g.,human serum,culture temperature in vitro,the pH of the culture medium,and others).Paradoxical effect of echinocandins has its own characteristics and need a further study.In China,there are a few reports about the instances of drug resistance because of the limited clinic application.The study on the echinocandins in prevalence rate of drug resistance and antifungal activity under different status has important clinical significance.

In this paper the four indexes of two mussels-Mytilus edulis and Mytilus coruscus were measured. The four indexes were protein, amino acids,unsaturated fatty acids and inorganic elements. The contents of protein and crude fats in Mytilus coruscus were higher than those in Mytilus edulis. The contents of essential amino acids have no difference between the two mussels. Mytilus coruscus is a heavy seafood,as there are much more glutamic acid, glycine and aspartic acid in it. The content of docosahexenoic acid (DHA)in M. coruscus was much more than that of M. edulis. Except for Aluminium and Selenium,the other 12 kinds of elements in M. edulis were higher than those in M. coruscus. The contents of polyunsatu-rated fatty acids(PUFAs) were much more than those of monounsaturated acids (MUFAs)in M. coruscus. There is little difference of the content between PUFAs and MUFAs in M. edulis.

This paper reported protein (50. 81%),rude fat (6. 24%),amio acids and mineral elements of abalone Haloitis discus hannai. And the shell and meat of the abalone for medical use was also introduced.

ObjectiveTo discuss the effects of adsorption(AP) combined with continuous venovenous hemofiltration(CVVH) on the serum inflammatory mediators levels in systemic inflammatory response syndrome (SIRS) patients.Methods Sixty-three SIRS patients were divided into treatment group (31 cases,AP combined with CVVH ) and control group (32 cases,CVVH ) by random digits table method.The changes of the serum tumor necrosis factor-alpha (TNF-α ),C-reactive protein (CRP),interleukin (IL)-1,IL-6 and IL-10 before and after treatment were compared in two groups.ResultsThere was no significant difference in the serum TNF-α,CRP,IL-1,IL-6,IL-10 before treatment between two groups (P ＞ 0.05 ).The serum TNF- α,CRP,IL- 1,IL-6,IL- 10 decreased after 2,26 and 50 h treatment compared with those before treatment in treatment group[after 2 h treatment:(226.4 ± 27.6) ng/L,(70.4 ± 22.1 ) mg/L,(30.1 ±2.9) ng/L,(227.5 ± 13.2) ng/L,(40.0 ±5.2) ng/L; after 26 h treatment:(165.3 ±24.5) ng/L,(58.2 ±25.1) mg/L,(18.2 ±2.7) ng/L,(82.4 ±7.2) ng/L,(26.2 ±4.3) ng/L; after 50 h treatment:( 120.6 ± 19.2) ng/L,(46.2 ± 24.6) mg/L,( 12.4 ± 2.3 ) ng/L,(38.1 ± 4.4 ) ng/L,( 15.2 ± 2.1 ) ng/L; before treatment:(350.8 ± 40.2) ng/L,( 126.4 ± 34.6) mg/L,(38.2 ± 3.6) ng/L,(307.7 ± 15.1 ) ng/L,(60.2 ± 9.3)ng/L,P ＜0.05].The serum TNF-α,CRP,IL-1,IL-6,IL-10 decreased after 26 and 50 h treatment compared with those before treatment in control group [after 26 h treatment:(262.7 ± 29.4) ng/L,(86.4 ±23.7) mg/L,(29.6 ± 3.1) ng/L,( 175.0 ± 10.6) ng/L,(42.7 ± 5.4) ng/L; after 50 h treatment:(219.3 ±25.6 ) ng/L,(75.6 ± 24.0) mg/L,(23.5 ± 2.8 ) ng/L,(99.0 ± 8.2 ) ng/L,(29.3 ± 4.8 ) ng/L; before treatment:(352.5 ± 40.4) ng/L,( 123.2 ± 35.2) mg/L,(37.5 ± 3.8) ng/L,(308.2 ± 15.3) ng/L,(58.4 ± 8.8) ng/L,P ＜0.05].There were significant differences in the serum TNF- α,CRP,IL-1,IL-6,IL-10 after 2,26 and 50 h treatment between two groups (P ＜ 0.05).ConclusionAP combined with CVVH can effectively decrease the serum inflammatory mediators in SIRS patients and it's therapeutic effect is superior to mere CVVH.

Objective:To explore the clinical and laboratory characteristics of acquired immunodeficiency syndrome (AIDS) patients complicated with disseminated nontuberculous mycobacterial (NTM) disease, in order to provide basis for clinical therapy.Methods:The clinical findings, imaging and etiological data of the 71 AIDS patients complicated with disseminated NTM disease admitted to Beijing You′an Hospital from June 2016 to June 2021 were retrospectively analyzed.Results:Among 71 patients with disseminated NTM disease, the most common initial symptom was fever, followed with cough, expectoration, fatigue, poor appetite, abdominal pain and diarrhea. Seventy point four percent (50/71) of these patients had at least two comorbidities, with oral candida infection, cytomegalovirus infection, syphilis, pneumocystis pneumonia and bacterial pneumonia being the most common. Hemoglobin ((87.8±24.2) g/L) and albumin ((27.3±7.0) g/L) levels significantly decreased, while erythrocyte sedimentation rate ((59.8±28.6) mm/1 h) and C-reactive protein ((74.7±50.8) mg/L) levels increased in most cases. The median CD4 + T lymphocyte count was 7×10 6/L. The median time of positive blood culture of NTM was 260 h. Among the 71 patients, 40 cases (56.3%) were infected with Mycobacterium avium, 15 cases (21.1%) with Mycobacterium intracellulare, 10 cases (14.1%) with Mycobacterium colombiense, three cases (4.2%) with Mycobacterium marseillense and three cases (4.2%) with Mycobacterium kansasii.The frequent imaging findings were patchy and nodular shadows in lungs, and most patients had mediastinal or hilar lymph node enlargement and splenomegaly. Conclusions:AIDS complicated with disseminated NTM disease is prevalently occurred in patients with severe immune deficiency, and most of the bacteria belong to the Mycobacterium avium- intracellulare complex. Early obtaining positive etiological results of NTM is essential to guide the correct clinical diagnosis and accurate treatment.

Objective:To extract and summarize the best evidence of early ambulation after anterior cervical surgery, so as to provide practical basis for early ambulation of clinical patients.Methods:The research questions were proposed based on the population, intervention, professional, outcome, setting and type of evidence (PIPOST) model. According to the "6S" model, the clinical guidelines, expert consensus, clinical decision-making, evidence summary, systematic reviews and randomized controlled trials related to "early postoperative activities of patients undergoing anterior cervical surgery" in databases such as UpToDate, British Medical Journal (BMJ) Best Practice website, Cochrane Library, China National Knowledge Infrastructure and WanFang Data were systematically retrieved. The retrieval time was from the establishment of the database to February 1, 2022. Two researchers independently evaluated the quality of the articles, and extracted and integrated the evidence of the articles meeting the quality standards.Results:A total of 10 articles were included, including two guidelines, three expert consensus, three systematic reviews, and two randomized controlled trials. It is summarized into 28 pieces of evidence and 7 dimensions, including multidisciplinary team cooperation, optimization of preoperative health education, preparation before ambulation, content of ambulation, multimodal analgesia management, nausea and vomiting management, and safety management of ambulation.Conclusions:The evidence included in this study provides a series of information for early ambulation after anterior cervical surgery. The medical and nursing staff should combine the evidence with the actual clinical situation, consider the value and expectation of the patient, comprehensively and individually evaluate the patient, and then make an early ambulation plan.

ObjectiveTo establish a geographical origin identification model for Foeniculi Fructus from Haiyuan， providing a new technical reference for the protection of Haiyuan's geo-authentic medicinal materials and its designation as a national geographical indication agricultural product. MethodsSamples of Foeniculi Fructus were collected from eight producing areas， including Minqin （Gansu）， Bozhou （Anhui）， Qingdao （Shandong）， Dezhou （Shandong）， Urumqi （Xinjiang）， Nujiang （Yunnan）， Gutuo （Inner Mongolia）， and Haiyuan （Ningxia）. Gas chromatography-ion mobility spectrometry （GC-IMS） was used to detect the volatile organic compounds （VOCs） in samples from these geographic origins. VOCs were qualitatively analyzed through dual matching with the National Institute of Standards and Technology （NIST） mass spectral database and the IMS drift time database. Using the Reporter module and Gallery Plot visualization tools within the LAV analytical platform， VOC fingerprint profiles characterizing geographic origins were constructed. A non-targeted analytical strategy was adopted， and 97 VOCs detected via GC-IMS were subjected to principal component analysis （PCA） and partial least squares discriminant analysis （PLS-DA） based on their differential distribution patterns to construct an origin identification model for Foeniculi Fructus from Haiyuan region. Key discriminative markers were screened using variable importance in projection （VIP） values greater than 1. ResultsA total of 97 VOCs were identified， including alcohols， aldehydes， ketones， esters， organic acids， terpenoids， ethers， alkenes， and benzenes. The PLS-DA model， based on VOCs data obtained by GC-IMS， effectively distinguished Foeniculi Fructus in Haiyuan region from those of other origins. During cross-validation， the model achieved a prediction parameter （Q²） of 0.976 and a goodness-of-fit parameter （R²） of 0.936， with no overfitting observed in permutation testing. Twelve key flavor markers with VIP > 1 were identified as characteristic indicators of Haiyuan origin. ConclusionA stable and highly predictive origin identification model for Foeniculi Fructus from Haiyuan was successfully established using GC-IMS technology， PLS-DA， and VIP-based marker screening. This model provides a novel technical strategy for accurately distinguishing Foeniculi Fructus in Haiyuan region from other regional varieties and offers new technical support for its protection as a geo-authentic medicinal material and a nationally designated geographical indication agricultural product in China.
