Qingfeitang， specialized in resolving phlegm to stop cough and producing fluid to moisten dryness， is a classic prescription inherited and developed by physicians of successive generations and has been included in the Catalogue of Ancient Classic Prescriptions （First Batch） published by the National Administration of Traditional Chinese Medicine （TCM） in 2018. Relevant ancient books data and modern literature were collected by bibliometrics to analyze the historic origin， formula composition， herb origin， preparation methods， processing methods， clinical effect， and indications of Qingfeitang. The key information of Qingfeitang was summarized to provide reference for the clinical application of the decoction. In this study， a total of 43 pieces of effective data on relevant ancient literature， including 35 ancient TCM books， were collected based on a systematic collation of relevant historic and modern literature. Results showed that "Qingfeitang" was originated from the "Renshen Qingfeitang" recorded in the Taiping Holy Prescriptions for Universal Relief from the Qing dynasty. The name of "Qinfeitang" was first recorded in the Yeshi Luyanfang written by YE Dalian in the Song dynasty. We suggested the modern dosage and usage of Qingfeitang as follows： "Scutellariae Radix of 5.60 g， Platycodon grandiflora， Poria， Tangerine， Fritillaria， and Cortex Mori of 3.73 g respectively， Angelicae Sinensis Radix， Asparagi Radix， Gardeniae Fructus， Armeniacae Semen Amarum， and Ophiopogonis Radix of 2.61 g respectively， Schisandra of 1 g， and Glycyrrhizae Radix et Rhizoma of 1.12 g， and they were taken 3 times daily. The above formula is recommended to be decocted with 400 mL of water， with 3.37 g ginger and 6 g jujubae fructus， to 320 mL， and taken after a meal， three times per day". Qingfeitang has the effect of resolving phlegm to stop cough and producing fluid to moisten dryness， specialized in treating cough， asthma， rash， and other symptoms in ancient times. Modern applications are mainly focused on the respiratory system， used for treating diseases such as bronchopneumonia and cough. The above research results provide a reference basis for the later development and research of Qingfeitang.

This paper discussed the historic evolution of Juanbitang and similar decoctions， clarified the historic development of Yangshi Juanbitang and Chengshi Juanbitang， and probed into the key information of the meaning， original plants， processing methods， and modern dosage and usage of Chengshi Juanbitang. A total of 267 pieces of relevant information were collected from ancient traditional Chinese medicine （TCM） books， among which 53 pieces of effective data were included in this study. The results showed that both Chenshi Juanbitang and Yangshi Juanbitang were originated from Duhuo Jishengtang recoded in the Important Prescriptions Worth a Thousand Gold for Emergency （Bei Ji Qian Jin Yao Fang）. According to the standard of "1 qian roughly equals 3.73 g" in the measurement system of the Qing Dynasty， we suggest Chenshi Juanbitang is composed of 3.73 g Notopterygii Rhizoma et Radix， 3.73 g Angelicae Pubescentis Radix， 3.73 g Gentianae Macrophyllae Radix， 11.19 g Angelicae Sinensis Radix， 11.19 g Mori Ramulus， 2.61 g Chuanxiong Rhizoma， 1.87 g Cinnamomi Cortex， 1.87 g stir-fried Glycyrrhizae Radix et Rhizoma， 7.46 g Piperis Kadsurae Caulis， 2.98 g Olibanum， and 2.98 g Aucklandiae Radix， which should be decocted with 600 mL water to reach a volume of 300 mL. The decoction should be taken 3 times a day before meals. Juanbitang， a classical formula specialized for treating impediment diseases， has the effects of dispelling wind， removing dryness， and alleviating impediment to relieve pain. It can be used for treating vexing pain in body， spasm of nape and back， and heaviness in waists and legs. Modern studies have shown that Juanbitang can be used for treating rheumatoid arthritis， knee osteoarthritis， and periarthritis of shoulder. The above results served as a reference for the future development of Juanbitang.

Stomach exuberance and spleen deficiency are common pathogenesis of many metabolic diseases. Through analyzing the pathogenesis of stomach exuberance and spleen deficiency， it is believed that its essence is stomach heat and spleen deficiency. Stomach heat includes gastrointestinal heat， spleen and stomach damp-heat， and spleen deficiency is divided into deficiency of spleen yin， deficiency of spleen qi ， and deficiency of spleen yang. It is suggested that the metabolic diseases of stomach-exuberance and spleen-deficiency syndrome can be divided into three categories，i.e. stomach-heat and spleen yin-deficiency， stomach-heat and spleen qi-deficiency， and stomach-heat and spleen yang-deficiency， and the main treatment methods are clearing and draining heat， nourishing yin and moistening intestine， clearing dampness and heat， strengthening spleen and qi， clearing dampness and heat， strengthening spleen and warming yang， respectively， with prescriptions as Maziren Pills （麻子仁丸）， Qinlian Pingwei Powder （芩连平胃散）， and Jiawei Lianli Decoction （加味连理汤） accordingly.

Objective To conduct hazard vulnerability analysis(HVA)in a blood bank,aimed to identify high-risk e-vents and optimize emergency management measures.Methods The risk event evaluation index system was established by referring to the Kaiser model and the situation of Guangzhou Blood Center,and risk events were ranked by risk matrix and Borda count.Results The top five events with the highest risk values identified by Kaiser model were information system e-mergencies(39.61％),extreme weather(38.03％),major public sentiment(37.86％),public health events(37.37％)and policy changes(37.24％).The results of risk matrix and Borda count revealed 1 extremely high-risk indicator as information system emergency,5 high-risk indicators with the highest risk being major public sentiment,11 medium-risk indicators with the highest risk being major medical disputes and 1 low-risk indicator as external fires.Conclusion Conducting HVA in combination with the actual situation of blood banks can effectively identify high-risk events and provide theoretical basis for improving emergency management measures.

BACKGROUND:The specific molecular mechanism of the transformation from normal healthy people to acute cervical spondylotic radiculopathy has not been clear,which needs to be further studied. OBJECTIVE:To investigate the differential expression of serum proteomics between normal healthy people and patients with acute cervical spondylotic radiculopathy,and to find and identify potential specific serum markers between them. METHODS:The serum samples of eight patients with acute cervical spondylotic radiculopathy and eight normal healthy people were collected,and the proteomic screening and analysis were performed by tandem mass tag combined with liquid chromatography-tandem mass spectrometry technology,in order to explore and identify serum proteins differentially expressed in patients with acute cervical spondylotic radiculopathy. RESULTS AND CONCLUSION:A total of 183 significantly differential proteins were screened by tandem mass tag technology,and 11 significantly differential proteins were identified(P＜0.05).Compared with normal healthy people,three differential proteins were significantly up-regulated,including human leukocyte antigen-A,secretoglobin family 1a member 1,and protein 4-hydroxyphenylpyruvate dioxygenase,and seven differential proteins were significantly down-regulated,such as immunoglobulin heavy constant gamma 3,skin factor,and myosin light chain 3,in patients with acute cervical spondylotic radiculopathy.Gene ontology enrichment analysis showed that these differential proteins participated in antigen binding,immunoglobulin receptor binding and other molecular functions.Protein-protein interaction analysis showed that among the common differential proteins between normal healthy people and patients with acute cervical spondylotic radiculopathy,HLA-A,HPD,PSMA3,DMKN,SCGB1A1,and MYL3 were located at the nodes of the functional network,and were closely related to the systems of body immunity,cellular inflammatory response,energy metabolism,and mechanical pressure.The significantly differential proteins HLA-A,HPD and MYL3 were verified by western blot,and the results were consistent with those of proteomics.To conclude,tandem mass tag combined with liquid chromatography-tandem mass spectrometry technology can be used to find the differentially expressed proteins in serum between normal healthy people and patients with acute cervical spondylotic radiculopathy.It is preliminarily believed that HLA-A,HPD and MYL3 may be specific serum markers of acute cervical spondylotic radiculopathy,providing a new direction for further research on its pathogenesis.

BACKGROUND:Previous studies have found that qi deficiency and blood stasis syndrome is the main syndrome among various TCM syndromes of cervical spondylotic myelopathy.However,there is no report on proteomic markers as early diagnosis indicators for the transformation of developmental cervical spinal stenosis with qi deficiency and blood stasis syndrome to cervical spondylotic myelopathy. OBJECTIVE:To explore serum proteomics difference between developmental cervical spinal stenosis and cervical spondylotic myelopathy and to find and identify the potential serum biomarkers between them. METHODS:Serum samples of nine patients with cervical spondylotic myelopathy of qi deficiency and blood stasis syndrome(experimental group)and nine patients with developmental cervical spinal stenosis of qi deficiency and blood stasis syndrome(control group)were collected.The proteomic analysis was carried out by Tandem Mass Tag combined with liquid chromatography tandem mass spectrometry,so as to find and identify differentially expressed proteins. RESULTS AND CONCLUSION:A total of 1027 significantly differential proteins were initially screened by TMT technology and 89 significantly differential proteins were finally identified(P<0.05).Compared with the control group,there were 45 up-regulated proteins in the experimental group,such as α-actinin-4,α-actinin-1,cell division control protein 42 homolog,integrin-linked protein kinase and B-actin.Conversely,there were 44 down-regulated proteins in the experimental group compared with the control group,such as fibronectin,fibrinogen γ chain,fibrinogen α chain,fibrinogen β chain.Gene ontology enrichment analysis indicated that these differential proteins were involved in signal receptor binding,kinase binding,protein kinase activity,integrin binding,actin filament binding and other molecular functions.Based on the Kyoto Encyclopedia of Genes and Genomes pathway analysis,20 common differential signal/metabolic pathways were identified,including Rap1 signaling pathway,adherens junction,tight junction,platelet activation,and regulation of actin cytoskeleton.Protein-protein interaction analysis showed that ILK,FGA,FGB,FGG,FN1,Cdc42,ACTN1,ACTN4 and ACTB were located at the nodes of protein-protein interaction network and were closely related to bone formation and destruction system,nervous system,coagulation system,cellular inflammation and other systems.To conclude,the serum differentially expressed proteins between developmental cervical spinal stenosis and cervical spondylotic myelopathy can be successfully screened by Tandem Mass Tag combined with liquid chromatography tandem mass spectrometry.ILK,FN1,CDC42 and ACTN 4 are identified as specific markers for the transformation of developmental cervical spinal stenosis with qi deficiency and blood stasis syndrome into cervical spondylotic myelopathy.These findings provide a basis for further clarifying the transformation mechanism.

Objective:To compare and analyze the differences in the measurement of intra-abdominal pressure in different positions of critically ill patients treated with extracorporeal membrane oxygenation (ECMO) combined with prone position integration, with a view to finding a more optimal intra-abdominal pressure monitoring strategy, which can provide a theoretical basis for clinical diagnosis and treatment.Methods:Forty critically ill patients who underwent ECMO combined with prone position integrated treatment in the department of Intensive Care Medicine of the First Affiliated Hospital of Guangxi Medical University from January 2020 to June 2023 were selected by convenience sampling method using an own-control trial. The differences in intra-abdominal pressure between supine position with head elevated at 0°, 15°and 30°and prone position with head high and foot low slopes at 0°, 15°and 30°were compared and analyzed. Heart rate, respiration, mean arterial pressure and oxygen saturation were also compared in patients in different positions.Results:There were 29 males and 11 females in 40 patients with the age of (62.58 ± 17.99) years.The intra-abdominal pressure in supine position with head elevated at 30° was (12.45 ± 3.43) mmHg(1 mmHg=0.133 kPa), which was higher than that of 0° and 15° of (9.38 ± 2.52) and (10.70 ± 2.95) mmHg, and the differences were statistically significant ( t=4.56, 2.45, both P<0.05);the difference in intra-abdominal pressure between 0° and 15° was not statistically significant ( P>0.05); the intra-abdominal pressure in prone position with head-high-foot-low slope of 30° was (12.92 ± 4.19) mmHg, which was higher than that of 0°and 15°of (9.67 ± 2.80), and (11.01 ± 3.10) mmHg, and the differences were statistically significant ( t=4.08, 2.32, both P<0.05); the difference in intra-abdominal pressure between 0° and 15° was not statistically significant ( P>0.05).The differences in intra-abdominal pressure between groups of supine bed head elevation 0°, 15°, 30°and prone position with head high and foot low slopes 0°, 15°, 30°were not statistically significant (all P>0.05). The differences in heart rate, respiration, mean arterial pressure and oxygen saturation in the supine position with head elevated at 0°, 15°and 30° were not statistically significant when compared within groups (all P>0.05); the differences in heart rate, respiration, mean arterial pressure and oxygen saturation in the prone position with head elevated with feet and feet on low slopes at 0°, 15°and 30°were not statistically significant when compared within groups (all P>0.05); and the differences in supine position with head elevated at 0°, 15°, 30°and prone head-height-foot-low slope 0°, 15°, 30°of heart rate, respiration, mean arterial pressure were not statistically significant (all P>0.05); supine bed head elevation 0°, 15°, 30°and prone head-height-foot-low slope 0°, 15°, 30°of oxygen saturation between the groups, the differences were statistically significant ( Z=6.85, 6.82, 6.68, all P<0.05). Conclusions:Intra-abdominal pressure can be measured in the 15° prone position in critically ill patients treated with ECMO combined with prone position integration; the different positions have little effect on vital signs, but the prone position significantly improves oxygen saturation.

Objective To establish a coronavirus(CoV)infection model using human nasal mucosa organoids for testing antiviral drugs and evaluate the feasibility of using human nasal mucosa organoids with viral infection as platforms for viral research and antiviral drug development.Methods Human nasal mucosa organoids were tested for susceptibility to SARS-CoV-2 and HCoV-OC43 pseudoviruses.In a P3 laboratory,nasal mucosa organoids were infected with the original strain of SARS-CoV-2 and 4 variant strains,and the infection conditions were optimized.The viral loads in the culture supernatants were measured at different time points using RT-qPCR,and immunofluorescence assay was employed to localize SARS-CoV-2 nucleocapsid protein to determine the type of the infected cells.In the optimized nasal mucosa viral infection model,the antiviral effects of camostat and bergamot extract(which were known to inhibit SARS-CoV-2)were tested and the underlying molecular mechanisms were explored.Results In the optimized nasal mucosa organoid models infected with SARS-CoV-2 and HCoV-OC43 pseudoviruses,the viral load in the culture supernatants increased significantly during the period of 2 to 24 h following the infection,which confirmed infection of the organoids by both of the pseudoviruses.The nasal mucosa organoids could be stably infected by the original SARS-CoV-2 strain and its 4 variant strains,validating successful establishment of the viral infection model,in which both camostat and bergamot extract exhibited dose-dependent antiviral effects.Conclusions Human nasal mucosa organoids with SARS-CoV-2 infection can serve as platforms for screening and testing antiviral drugs,particularly those intended for nasal administration.
