ObjectiveTo screen the differential markers by analyzing volatile components in Dalbergia odorifera and its counterfeits， in order to provide reference for authentication of D. odorifera. MethodThe volatile components in D. odorifera and its counterfeits were detected by headspace gas chromatography-mass spectrometry（HS-GC-MS）， and the GC conditions were heated by procedure（the initial temperature of the column was 50 ℃， the retention time was 1 min， and then the temperature was raised to 300 ℃ at 10 ℃ for 10 min）， the carrier gas was helium， and the flow rate was 1.0 mL·min^-1， the split ratio was 10∶1， and the injection volume was 1 mL. The MS conditions used electron bombardment ionization（EI） with the scanning range of m/z 35-550. The compound species were identified by database matching， the relative content of each component was calculated by the peak area normalization method， and principal component analysis（PCA）， orthogonal partial least squares-discrimination analysis（OPLS-DA） and cluster analysis were performed on the detection results by SIMCA 14.1 software， and the differential components of D. odorifera and its counterfeits were screened out according to the variable importance in the projection（VIP） value>2 and P<0.05. ResultA total of 26， 17， 8， 22， 24 and 7 volatile components were identified from D. odorifera， D. bariensis， D. latifolia， D. benthamii， D. pinnata and D. cochinchinensis， respectively. Among them， there were 11 unique volatile components of D. odorifera， 6 unique volatile components of D. bariensis， 3 unique volatile components of D. latifolia， 6 unique volatile components of D. benthamii， 8 unique volatile components of D. pinnata， 4 unique volatile components of D. cochinchinensis. The PCA results showed that， except for D. latifolia and D. cochinchinensis， which could not be clearly distinguished， D. odorifera and other counterfeits could be distributed in a certain area， respectively. The OPLS-DA results showed that D. odorifera and its five counterfeits were clustered into one group each， indicating significant differences in volatile components between D. odorifera and its counterfeits. Finally， a total of 31 differential markers of volatile components between D. odoriferae and its counterfeits were screened. ConclusionHS-GC-MS combined with SIMCA 14.1 software can systematically elucidate the volatile differential components between D. odorifera and its counterfeits， which is suitable for rapid identification of them.

Objective To analyse the concept of subjective financial distress in cancer patients.Methods Papers in regarding the subjective financial distress were retrieved from the databases such as China National Knowledge Infrastructure(CNKI),Wangfang Database,PubMed,Cochrane Library,Web of Science,CINAHL,and Embase from the inceptions to 16th October,2022.Walker and Avant's concept analysis was performed to analyse the acquired articles.Results A total of 48 articles were retrieved and included in the study.Walker and Avant's concept analysis showed that the subjective financial distress in the patients was subject to the 3 defining attributes:perceived economic risk,coping behaviours,and negative emotional reactions.The antecedents of this distress included individual factors,disease and treatment factors,and social factors.The consequences of them were the increase in negative health behaviours and poorer quality of life.Conclusions The attributes,antecedents and consequences of subjective financial distress,as identified through the conceptual analysis,can serve as a reference for subsequent researches.In future studies,it would be beneficial by further exploring the connotation by considering China's healthcare system.

Background and Aims:Accurate early pathogen diagnosis is a breakthrough for improving the prognosis of infectious pancreatic necrosis(IPN)patients.However,there is currently a lack of efficient methods for early identification of IPN in clinical settings.This study was performed to assess the application value of next-generation sequencing technology based on metagenomic capture(MetaCAP)in the pathogen diagnosis of IPN. Methods:A prospective study was conducted on 29 patients suspected of having acute necrotizing pancreatitis at Xiangya Hospital of Central South University between January and July 2024.Blood samples were tested using MetaCAP and conventional pathogen culture.The results of peritoneal fluid pathogen culture were used as the gold standard to compare the diagnostic efficacy of the two methods. Results:Due to three cases lacking peritoneal fluid culture results,a total of 26 cases were included in the final analysis.The overall mortality rate was 23.1％(6/26).During hospitalization,9 cases(34.6％)were diagnosed with IPN.The sensitivity and negative predictive value of MetaCAP for diagnosing IPN were significantly higher than those of conventional pathogen culture(77.8％vs.11.1％,P=0.031;86.7％vs.65.2％,P=0.032),while the differences in specificity(76.5％vs.88.2％,P=0.689)and positive predictive value(63.6％vs.33.3％,P=0.347)between the two methods were not statistically significant.The average detection time for MetaCAP was 33(20-49)h,while microbial culture took 125(45-142)h,with a significant difference(P＜0.001).The average cost for blood MetaCAP testing was 2 500 yuan per case,but it accounted for only 1.19％of the average hospitalization cost. Conclusion:MetaCAP has significant value in the early pathogen diagnosis of IPN,with a shorter detection time,good testing efficacy,and health-economic value,demonstrating a promising clinical application prospect.

Objective:To investigate the application value of metagenomic next-genera-tion sequencing (mNGS) in pathogenic diagnosis of suspected infected severe acute pancreatitis (SAP).Methods:The prospective study was conducted. The clinical data of 25 patients with suspected infected SAP who were admitted to the Xiangya Hospital of Central South University from May to September 2023 were collected. Upper limb venous blood samples of all the patients were collected for both of mNGS and routine pathogen microbial culture. Observation indicators: (1) grouping situations of the enrolled patients; (2) comparison of the diagnostic efficiency of mNGS and routine pathogen microbial culture; (3) results of peripheral blood pathogen microbial testing and peri-pancreatic effusion microbial culture; (4) testing time and cost. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3). Count data were expressed as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Results:(1) Grouping situations of the enrolled patients. A total of 25 patients were selected for eligibility. There were 18 males and 7 females, aged 48(40,59)years. The duration of hospital stay of 25 patients was 30(20,50)days. The etiologies of 25 patients included 14 cases of hyperlipidemic pancreatitis, 8 cases of biliary pancreatitis, 1 case of alcohol-induced acute pancreatitis, and 2 cases of pancreatitis caused by other causes. Of the 25 patients, there were 17 cases with infected pancreatic necrosis (IPN) including 7 cases of death, and 8 cases with sterile pancreatic necrosis including no death. (2) Comparison of the diagnostic efficiency of mNGS and routine pathogen microbial culture. The positive rates of mNGS and routine pathogen microbial culture in diagnosis of suspected infected SAP were 72.0%(18/25) and 32.0%(8/25), respectively, showing a significant difference between them ( χ2=8.01, P<0.05). The sensitivity and negative predic-tive value of mNGS and routine pathogen microbial culture in diagnosis of IPN were 94.1%(16/17), 35.3%(6/17) and 85.7%(6/7), 35.3%(6/17), showing significant differences between them ( χ2=12.88, 5.04, P<0.05). The specificity and positive predictive value of mNGS and routine pathogen microbial culture in diagnosis of IPN were 75.0%(6/8), 75.0%(6/8) and 88.9%(16/18), 75.0%(6/8), showing no significant difference between them ( χ2=0, 0.82, P>0.05). (3) Results of peripheral blood pathogen microbial testing and peripancreatic effusion microbial culture. Of the 17 patients with IPN, 36 strains of pathogenic bacteria were detected by mNGS, and 6 strains were detected by routine pathogen microbial culture. There were 16 of 17 patients with IPN showing positive mNGS pathogenic testing, of which 13 cases were consistent with the pathogenic testing results of peri-pancreatic effusion microbial culture, showing a consistency rate of 76.5%(13/17). There were 6 pati-ents with IPN showing positive routine pathogen microbial culture, with a consistency rate of 35.3%(6/17) to peripancreatic effusion microbial culture. (4) Testing time and cost. Testing time of mNGS and routine pathogen microbial culture were (43±17)hours and (111±36)hours, showing a signifi-cant difference between them ( t=9.31, P<0.05). Testing cost of mNGS was (2 267±0)yuan/case, accoun-ting for 1.7% of the hospitalization expenses of (133 759±120 744)yuan/case. Testing cost of routine pathogen microbial culture was (240±0)yuan/case, accounting of 0.2% of the hospitalization expenses. Conclusion:mNGS has important value for early pathogenic diagnosis of suspected infected SAP, and has a high timeliness.

ObjectiveTo analyze the migrating components absorbed into blood of the aqueous extract of Euphorbia helioscopia， and to explore the pharmacodynamic material basis of the aqueous extract of E. helioscopia against chronic obstructive pulmonary disease（COPD）. MethodUltra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS/MS） was used to detecte the migrating components absorbed into blood of rats after intragastric administration of aqueous extract of E. helioscopia. An Agilent RRHD SB-C₁₈ column（3 mm×100 mm， 1.8 μm） was used with 0.1% formic acid aqueous solution（A）-acetonitrile（B） as the mobile phase for gradient elution（0-15 min， 5%-30%B； 15-20 min， 30%-50%B； 20-30 min， 50%-95%B； 30-35 min， 95%-5%B）， and the detection wavelength of 190-800 nm， column temperature of 40 ℃， flow rate of 0.3 mL∙min^-1 and injection volume of 4 μL. The electrospray ionization（ESI） was used in positive and negative ion modes， and the detection range was m/z 50-1 250. Network pharmacology was used to screen out the key components and the key targets of COPD through the interaction analysis. Metascape database was used to predict the molecular function， biological process， cellular composition and signal pathways mainly involved in the anti-COPD effect of E. helioscopia. Molecular docking technique was used to determine the affinity of key targets with key components. ResultA total of 29 migrating components absorbed into blood of rats were identified after intragastric administration of aqueous extract of E. helioscopia， 9 of which were prototype components and 20 were metabolites. Network pharmacological analysis showed that luteolin， quercetin， apigenin， naringenin and helioscopinolide C were the key components of E. helioscopia against COPD， and vascular endothelial growth factor A（VEGFA）， albumin（ALB）， protein kinase B1（Akt1）， tumor necrosis factor（TNF） and interleukin-6（IL-6） were the key targets. Molecular docking results showed that one diterpene lactone（helioscopinolide C） and three flavonoids（naringenin， luteolin， apigenin） in the migrating components absorbed into blood all had strong binding activity to the key targets of E. helioscopia against COPD. ConclusionNaringenin， helioscopinolide C， luteolin and apigenin may be the main anti-COPD active substances of E. helioscopia.

Objective:To explore the role of clinical pharmacists participating in the management of prophylactic antibiotics during the perioperative period of thoracic surgery, and to evaluate the effects after participating in the practice.Methods:The use of antimicrobials during the perioperative period of thoracic surgery in Wenjiang Hospital of Sichuan Provincial People's Hospital in August 2019 (pre-practice) was retrospectively analyzed. The existing problems were summarized, and the possible causes of the existing problems were analyzed. The improvement measures were jointly developed by clinical pharmacists and physicians. Clinical pharmacists continued to manage the use of antimicrobials by means of medication order reviews, ward rounds for pharmacy service, and medication training. The use of prophylactic antibiotics during the perioperative period of thoracic surgery was compared between August 2019 (pre-practice group) and December 2019 (post-practice group) and the practical effect was evaluated.Results:Clinical pharmacists reviewed perioperative patients' medication orders once a day, ward rounds for pharmacy service twice a week, and medication training once a month. Twenty-two patients were enrolled before practice, and 26 patients were enrolled after practice. There were no significant differences in age, sex, body weight, operative time, type of surgical incision, and preventive use of antibiotics between the two groups (all P > 0.05). In the post-practice group, the appropriate time for preoperative administration was 100.0%, which was significantly higher than 88.2% in the pre-practice group. The reasonable rate of preoperative preventive drug selection was 100.0%, which was significantly higher than 44.4% in the pre-practice group ( χ2 = 17.50, P < 0.001). In the post-practice group, the duration of preventive medication was (1.82 ± 0.59) days, which was significantly shorter than (7.54 ± 3.25) days in the pre-practice group ( t = 11.97, P < 0.001). In the post-practice group, the cost of antibacterial drugs was 316.00(237.00,454.25) yuan, which was significantly lower than 1 136.00(391.81 , 2 184.65) yuan in the pre-practice group ( Z = -2.78, P < 0.05). The defined daily dose of antibiotics among inpatients was 2.67(2.00,3.42), which was significantly lower than 8.88(3.92 , 19.18) in the pre-practice group ( Z = -3.26, P < 0.05). There were no significant differences in the incidence of postoperative pulmonary infection and total length of hospital stay between the two groups (both P > 0.05). Conclusion:Clinical pharmacists participating in the management practice of perioperative prophylactic antibiotics in thoracic surgery can effectively promote the rational application of perioperative antibiotics, markedly improve the reasonable rate of prophylactic drug delivery, shorten the course of prophylactic drugs, reduce the cost of antibiotics, decrease the defined daily dose of antibiotics, without increasing the risk of postoperative pulmonary infection and the total length of hospital stay.

Financial toxicity increases the risk of negative health outcomes for cancer patients,and therefore timely intervention is crucial.Research on intervention in financialtoxicity has made some progress abroad,however,there is limited research in China currently.This article reviewed the intervention strategies for financial toxicity in cancer patients abroad and provides a reference for establishing systematic intervention programs in clinical work.

Ulcerative colitis(UC)is characterized by chronic relapsing intestinal inflammation.Currently,there is no effective treatment for the disease.According to our preliminary data,1,8-cineole,which is the main active compound of Amomum compactum Sol.ex Maton volatile oil and an effective drug for the treat-ment of pneumonia,showed remarkable anti-inflammatory effects on colitis pathogenesis.However,its mechanism of action and direct targets remain unclear.This study investigated the direct targets and mechanism through which 1,8-cineole exerts its anti-inflammatory effects using a dextran sulfate so-dium salt-induced colitis mouse model.The effects of 1,8-cineole on macrophage polarization were investigated using activated bone marrow-derived macrophages and RAW264.7 cells.In addition,1,8-cineole targets were revealed by drug affinity responsive target stability,thermal shift assay,cellular thermal shift assay,and heat shock protein 90(HSP90)adenosine triphosphatases(ATPase)activity assays.The results showed that 1,8-cineole exhibited powerful anti-inflammatory properties in vitro and in vivo by inhibiting the macrophage M1 polarization and protecting intestinal barrier function.Mech-anistically,1,8-cineole directly interacted with HSP90 and decreased its ATPase activity,also inhibited nucleotide-binding and oligomerization domain-,leucine rich repeat-,and pyrin domain-containing 3(NLRP3)binding to HSP90 and suppressor of G-two allele of SKP1(SGT1)and suppressed NLRP3 inflammasome activation in macrophages.These results demonstrated that 1,8-cineole is a potential drug candidate for UC treatment.

Pulmonary blast injury has become the main type of trauma in modern warfare, characterized by externally mild injuries but internally severe injuries, rapid disease progression, and a high rate of early death. The injury is complicated in clinical practice, often with multiple and compound injuries. Currently, there is a lack of effective protective materials, accurate injury detection instrument and portable monitoring and transportation equipment, standardized clinical treatment guidelines in various medical centers, and evidence-based guidelines at home and abroad, resulting in a high mortality in clinlcal practice. Therefore, the Trauma Branch of Chinese Medical Association and the Editorial Committee of Chinese Journal of Trauma organized military and civilian experts in related fields such as thoracic surgery and traumatic surgery to jointly develop the Clinical treatment guideline for pulmonary blast injury ( version 2023) by combining evidence for effectiveness and clinical first-line treatment experience. This guideline provided 16 recommended opinions surrounding definition, characteristics, pre-hospital diagnosis and treatment, and in-hospital treatment of pulmonary blast injury, hoping to provide a basis for the clinical treatment in hospitals at different levels.
