Jianghuanglian is one of the representative processed products of Coptidis Rhizoma for treating cold syndrome with drugs of heat nature， and ginger is used to restrict the bitter cold of Coptidis Rhizoma， which can be traced back to Bojifang， and it is suitable for stagnation of damp-heat in middle-jiao， cold-heat mutual knots and other symptoms. Jianghuanglian retains the alkaloids， phenylpropanoids and flavonoids of Coptidis Rhizoma， and also introduces gingerol components such as 6-gingerol in ginger， which has pharmacological activities such as anti-inflammatory， antibacterial， anti-tumor， and improving gastrointestinal function. The 2020 edition of Chinese Pharmacopoeia and many local processing specifications have included the traditional processing process and quality standards of Jianghuanglian， but the specific process parameters and quality standards are incomplete， which limits the production and clinical application of this processed product. By summarizing the processing history， process research， quality evaluation， pharmacodynamic and medicinal property changes and application of Jianghuanglian in the past 20 years， there are differences in the processing methods and standards in various provinces and cities， which are mainly reflected in the preparation method， dosage， processing process and quantitative standards of ginger juice. In addition， there are also certain differences in the changes of the main components of Jianghuanglian prepared from ginger or dried ginger， as well as their efficacy and medicinal properties. The research on the processing process of Jianghuanglian plays an important role in improving its quality standards， and this review can provide a reference for improving the quality evaluation system of Jianghuanglian.

First recorded in an official medical book from the Northern Song Dynasty called Taiping Huimin Heji Ju Fang （Prescriptions of the Bureau of Taiping People's Welfare Pharmacy）， Xiaoyaosan has been developed and refined over generations and is preserved to this day. It specializes in soothing the liver，resolving stagnation，fortifying the spleen，and nourishing blood. In this study，ancient traditional Chinese medicine （TCM） books and contemporary studies were reviewed to obtain information on Xiaoyaosan using bibliometrics，including its historical development，dosage，origin，processing methods，decoction dosage，and ancient and modern indications. Furthermore，a question regarding the presence of Zingiberis Rhizoma Recens and Menthae Haplocalycis Herba in Xiaoyaosan was investigated，and a table of key information on Xiaoyaosan was compiled，providing references for developing Xiaoyaosan preparations. According to the weight and measurement system of the Song dynasty，the contemporary equivalent formulation of the decocted Xiaoyaosan consists of 20.65 g of Glycyrrhizae Radix et Rhizoma and 41.3 g of Angelica Sinensis Radix，Poria，Paeoniae Radix Alba，Atractylodis Macrocephalae Rhizoma，and Bupleuri Radix. The formulation is processed to obtain a mixed powder with a particle size of 10 mesh. For each dose，8.25 g of the mixed powder is combined with 1 g of unprocessed Zingiberis Rhizoma Recens and 0.62 g of Menthae Haplocalycis Herba in 300 mL of water. The mixture is decocted until the volume reaches 210 mL，and the residue is then removed，with no specific timing required for administration. After the processing，each dose consists of approximately 0.75 g of Glycyrrhizae Radix et Rhizoma and 1.50 g of Radix Angelica Sinensis，Poria，Paeoniae Radix Alba，Atractylodis Macrocephalae Rhizoma，and Bupleuri Radix. Ancient medical literature shows that Xiaoyaosan primarily treats blood deficiency and overstrain，specifically for symptoms including heat caused by blood deficiency and fatigue，irregular menstruation，headache，eye soreness，pain in the ribs and limbs，and emaciation and bone steaming. In the Qing Dynasty，ZHANG Lu clearly proposed the pathogenesis of liver depression，and since then，the use of Xiaoyaosan in treating various syndromes associated with liver depression has been highly praised by physicians in the Qing dynasty and modern times. Xiaoyaosan has a wide application in modern clinical practices，involving digestive diseases，gynecological diseases，psychological diseases，nervous system diseases，and otorhinolaryngologic diseases. Moreover，it is most commonly used to treat depression and other diseases complicated with depression，hyperplasia of the mammary gland，etc. The key information on Xiaoyaosan and its clinical applications in ancient and modern times investigated in the study could serve as a scientific reference for in-depth research and extended clinical applications of the prescription.

Objective To explore the efficacy and safety of recombinant human anti-severe acute respiratory syn-drome coronavirus 2(anti-SARS-CoV-2)monoclonal antibody injection(F61 injection)in the treatment of patients with coronavirus disease 2019(COVID-19)combined with renal damage.Methods Patients with COVID-19 and renal damage who visited the PLA General Hospital from January to February 2023 were selected.Subjects were randomly divided into two groups.Control group was treated with conventional anti-COVID-19 therapy,while trial group was treated with conventional anti-COVID-19 therapy combined with F61 injection.A 15-day follow-up was conducted after drug administration.Clinical symptoms,laboratory tests,electrocardiogram,and chest CT of pa-tients were performed to analyze the efficacy and safety of F61 injection.Results Twelve subjects(7 in trial group and 5 in control group)were included in study.Neither group had any clinical progression or death cases.The ave-rage time for negative conversion of nucleic acid of SARS-CoV-2 in control group and trial group were 3.2 days and 1.57 days(P=0.046),respectively.The scores of COVID-19 related target symptom in the trial group on the 3rd and 5th day after medication were both lower than those of the control group(both P＜0.05).According to the clinical staging and World Health Organization 10-point graded disease progression scale,both groups of subjects improved but didn't show statistical differences(P＞0.05).For safety,trial group didn't present any infusion-re-lated adverse event.Subjects in both groups demonstrated varying degrees of elevated blood glucose,elevated urine glucose,elevated urobilinogen,positive urine casts,and cardiac arrhythmia,but the differences were not statistica-lly significant(all P＞0.05).Conclusion F61 injection has initially demonstrated safety and clinical benefit in trea-ting patients with COVID-19 combined with renal damage.As the domestically produced drug,it has good clinical accessibility and may provide more options for clinical practice.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

Biological evidence is relatively common evidence in criminal cases,and it has strong pro-bative power because it carries DNA information for individual identification.At the scene of fire-related cases,the complex thermal environment,the escape of trapped people,the firefighting and res-cue operations,and the deliberate destruction of criminal suspects will all affect the biological evi-dence in the fire scene.Scholars at home and abroad have explored and studied the effectiveness of biological evidence identification in fire scenes,and found that the blood stains,semen stains,bones,etc.are the main biological evidence which can be easily recovered with DNA in fire scenes.In order to analyze the research status and development trend of biological evidence in fire scenes,this paper systematically sorts out the relevant research,mainly including the soot removal technology,appearance method of typical biological evidence,and possibility of identifying other biological evidence.This pa-per also prospects the next step of research direction,in order to provide reference for the identifica-tion of biological evidence and improve the value of biological evidence in fire scenes.

Yuhuanglian is one of the representative processed products to change the medicinal properties of Coptidis Rhizoma， which was first published in Hanshi Yitong. Its processing method is to mix Evodiae Fructus juice with Coptidis Rhizoma with stir-frying for drying， that is， Coptidis Rhizoma processed with Evodiae Fructus juice can reduce the bitterness and cold properties on the basis of retaining the effect of purging fire and detoxification， so that Yuhuanglian is cold but not stagnant， which can clear dampness-heat in Qifen， and is effective in treating the liver-qi invading stomach， vomiting and swallowing acid. As a representative variety of processing with medicine juice， Yuhuanglian is included in the 2020 edition of Chinese Pharmacopoeia and local processing standards， and its processing technology research and optimization has been attracting much attention. Modern studies have shown that Yuhuanglian not only contains berberine， jatrorrhizine， palmatine and other components， but also contains evodiamine， rutaecarpine， limonin and other components from Evodiae Fructus， which have anti-inflammatory， antibacterial， anti-tumor and other pharmacological activities. This paper collated and summarized the related research reports of Yuhuanglian in the past 20 years from the perspectives of processing history， efficacy and medicinal properties， quality evaluation and clinical application， and found that the processing methods and standards of Yuhuanglian were quite different in different provinces and cities， mainly involving the preparation and dosage of Evodiae Fructus juice and the criteria for the processing end point. In addition， the changes in the major components of Yuhuanglian before and after processing varied greatly among different studies， presumably related to the different processes and quality standards， this paper summarized the processing history， technology， pharmacodynamics， quality evaluation and clinical application of Yuhuanglian， in order to provide reference for improving its quality evaluation system.

ObjectiveTo investigate the effect of modified Simiaosan on miR-223-3p and NOD-like receptor thermal protein domain associated protein 3 （NLRP3）/interleukin-1β （IL-1β） signaling pathway in rat model with acute gouty arthritis （AGA） and explore the anti-inflammatory mechanism of modified Simiaosan on AGA. MethodA total of 72 8-week-old male SD rats were selected. They were divided into blank group， model group， colchicine group （0.3 mg·kg^-1）， high-dose modified Simiaosan group （31.75 g·kg^-1）， medium-dose modified Simiaosan group （15.75 g·kg^-1）， and low-dose modified Simiaosan group （7.875 g·kg^-1） according to random number table method， with 12 rats in each group. Except for the blank group， monosodium urate （MSU） crystal suspension was injected into the right ankle joint of rats by the Coderre method in other groups to replicate the rat model with AGA. The drug administration groups were given the corresponding drug solution by gavage， and the model group and the blank group were given an equal volume of sterile sodium chloride solution by gavage for one week. The circumference of the rats' ankle joint was measured， and the swelling degree of the ankle joint was calculated. Hematoxylin-eosin （HE） staining was used to detect the pathological morphological changes in the synovial tissue of the ankle joint. The levels of IL-1β， tumor necrosis factor-α （TNF-α）， and interleukin-6 （IL-6） in the serum of rats in each group were detected by enzyme-linked immunosorbent assay （ELISA）. Western blot was used to detect the protein expressions of NLRP3， Caspase-1， and apoptosis-related spot-like protein （ASC） in synovial tissue of rats in each group， and real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expressions of NLRP3， Caspase-1， and ASC and the expression of miR-223-3p in synovial tissue of rats. ResultCompared with that in the normal group， the swelling degree of the ankle joint in the model group was higher （P<0.01）， and the synovial tissue structure was disordered. Synovial cells proliferated obviously， and a large number of inflammatory cells were infiltrated. The levels of IL-1β， IL-6， and TNF-α in the serum of the model group increased significantly （P<0.01）， and the protein and mRNA expressions of NLRP3， Caspase-1， and ASC increased， while expression of miR-223-3 decreased. Compared with the model group， the swelling degree of ankle joint in the colchicine group and high-dose and medium-dose modified Simiaosan groups was lower （P<0.05）. Synovial cell proliferation and inflammatory cell infiltration of the colchicine group and high-dose， medium-dose， and low-dose modified Simiaosan groups were reduced to varying degrees， among which the colchicine group and high-dose modified Simiaosan group improved most obviously. The levels of IL-1β， IL-6， and TNF-α in the serum of rats in different dose groups of modified Simiaosan and colchicine group decreased significantly （P<0.01）， while the protein and mRNA expressions of NLRP3， Caspase-1， and ASC increased （P<0.01）. The expression of miR-223-3p in synovial tissue of the medium-dose and high-dose modified Simiaosan groups and colchicine group increased significantly （P<0.01）. Compared with those in the colchicine group， the levels of IL-1β， IL-6， and TNF-α in the low-dose modified Simiaosan group increased greatly （P<0.01）. In the medium-dose modified Simiaosan group， the protein expressions of NLRP3， Caspase-1， and ASC increased， and the expression of miR-223-3p decreased （P<0.05）. In the low-dose modified Simiaosan group， the levels of IL-1β， IL-6， and TNF-α increased greatly （P<0.01）， as well as the protein and mRNA expressions of NLRP3， Caspase-1， and ASC， while the expression of miR-223-3p was decreased （P<0.01）. ConclusionModified Simiaosan may play an anti-inflammatory role by intervening in the NLRP3/IL-1β signaling pathway via regulating miR-223-3p.

Objective Viral encephalitis is an infectious disease severely affecting human health.It is caused by a wide variety of viral pathogens,including herpes viruses,flaviviruses,enteroviruses,and other viruses.The laboratory diagnosis of viral encephalitis is a worldwide challenge.Recently,high-throughput sequencing technology has provided new tools for diagnosing central nervous system infections.Thus,In this study,we established a multipathogen detection platform for viral encephalitis based on amplicon sequencing. Methods We designed nine pairs of specific polymerase chain reaction(PCR)primers for the 12 viruses by reviewing the relevant literature.The detection ability of the primers was verified by software simulation and the detection of known positive samples.Amplicon sequencing was used to validate the samples,and consistency was compared with Sanger sequencing. Results The results showed that the target sequences of various pathogens were obtained at a coverage depth level greater than 20×,and the sequence lengths were consistent with the sizes of the predicted amplicons.The sequences were verified using the National Center for Biotechnology Information BLAST,and all results were consistent with the results of Sanger sequencing. Conclusion Amplicon-based high-throughput sequencing technology is feasible as a supplementary method for the pathogenic detection of viral encephalitis.It is also a useful tool for the high-volume screening of clinical samples.

Objective:Network Meta-analysis was used to compare the predictive value of different detection indicators for bloodstream infection in ICU adult patients, providing evidence-based basis for early clinical diagnosis of bloodstream infection in patients.Methods:Cochrane Library, PubMed, Embase, CINAHL, Web of Science, China National Knowledge Infrastructure (CNKI), VIP, Wanfang database and SinoMed were searched by computer. All the experimental studies on different detection indicators for predicting bloodstream infection in ICU adult patients were collected. The retrieval time limit was from the establishment of the database to July 9, 2023.Two researchers independently searched and screened the literature according to the literature inclusion and exclusion criteria, strictly evaluated the quality of the included literature, extracted data, and used Revman5.4 software for Meta-analysis.Results:A total of 13 studies were included. The ranking results of network Meta-analysis showed that among different detection indicators, procalcitonin (PCT), C-reactive protein (CRP), combined with (IL-6) had the highest area under the cumulative rank probability curve for sensitivity, negative predictive value and accuracy (85.08%, 90.41%, 79.39%). PCT, hypersensitive-C-reactive protein(hs-CRP) combined with IL-6 had the highest area under the cumulative rank probability curve of specificity and positive predictive value (68.47%, 77.92%). The results of cluster analysis showed that PCT+hs-CRP+IL-6 and PCT+CRP+IL-6 were the farthest distance from the origin compared with other detection indicators.Conclusions:PCT+CRP/hs-CRP+IL-6 can be used as a predictor for the diagnosis of bloodstream infection in ICU adult patients. In a single detection, pro-adrenomendullin may be the direction of future research, but due to the small sample size, the above conclusions need to be verified by more large sample and high quality studies.

Objective To investigate the effect of artesunate(ART)on neuroinflammation in depressed mice by regulating the cyclic guanosine monophosphate-adenosine monophosphate synthase(cGAS)-stimulator of interferon gene(STING)pathway.Methods Mice were divided into model group,control group,low-dose ART group,high-dose ART group,fluoxetine group,and high-dose ART+RocA(cGAS-STING pathway activator)group.Sugar solution consumption experiment and forced swimming experiment were applied to evaluate the depressive behavior of mice;HE staining microscopy was applied to detect pathological changes in hippocampal tissue;ELISA method was applied to detect the level of interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),serotonin(5-HT)and dopa-mine(DA);TUNEL staining microscopy was applied to detect neuronal apoptosis;Western blot was applied to detect Bcl-2 associated X protein(Bax),p53,cGAS,and STING proteins.Results Compared to the control group,the mice in the model group exhibited neuronal pustule degeneration,the sugar water consumption rate,level of 5-HT and DA decreased,the rest time of forced swimming increased.The level of IL-6 and TNF-α,neuronal apoptosis rate,expression of Bax,p53,cGAS,and STING proteins all elevated(P＜0.05);Compared with model group,the damage to hippocampus neurons in the ART low-dose group,ART high-dose group and fluoxetine group neuronal pus-tular degeneration was alleviated,while sugar water consumption rate,5-HT,and DA levels increased,the rest time of forced swimming reduced,the level of IL-6 and TNF-α,neuronal apoptosis rate and the expression of Bax,p53,cGAS,and STING proteins reduced(P＜0.05);RocA reversed the improvement effect of high-dose ART on depression in mice.Conclusions ART inhibits neuroinflammation and neuronal apoptosis in depressed mice,and up-regulates amine neurotransmitters expression.The mechanism is potentially related to the blocking of cGAS-STING pathway.
