The abnormal accumulation of neutrophil extracellular traps （NETs） can promote the initiation and progression of pancreatic cancer， which is considered a potential therapeutic target for this disease. The Miraculous Pivot·Inquiry About Statement （《灵枢·口问》） have recorded the concept of "defensive qi stagnation". Based on the recognition that the function of defensive qi is similar to the immune function of neutrophils， and combining traditional Chinese medicine theory with clinical practice， it is proposed that the abnormal accumulation of NETs may be a pathological product of "defensive qi stagnation"， with the spleen being the critical site of pathology. Further exploring the application strategy of cleaning spleen and restoring defensive qi method in pancreatic cancer treatment， it is proposed to employ three approaches such as dredging method to eliminate spleen stagnation and inhibit pancreatic cancer proliferation， cleaning method to remove spleen dampness and suppress the inflammatory micro-environment， and tonifying method to strengthen Weiqi and to improve the immune microenvironment， which aims to provide new insights for the clinical treatment of pancreatic cancer with traditional Chinese medicine.

ObjectiveThis paper aims to systematically collect and organize ancient and modern clauses and studies containing Xieqingwan， excavate and analyze the key information of Xieqingwan， and provide a reference for facilitating the development of the classic formula Xieqingwan. MethodsThe composition， dosage， decocting methods， usage， and other key information of Xieqingwan in ancient traditional Chinese medicine books were collected and analyzed by means of literature research and metrological methods. The modern clinical application of Xieqingwan was summarized. ResultsA total of 42 pieces of effective data involving 32 ancient traditional Chinese medicine books were collected. Xieqingwan was first recorded in Xiaoer Yaozheng Zhijue. The drug origin of this formula is basically clear in the ancient traditional Chinese medicine books. The modern drug usage and decocting method were as follows： Angelicae Sinensis Radix， Gentianae Radix et Rhizoma， Chuanxiong Rhizoma， Gardenia seeds， Radix et Rhizoma Rhei， Notopterygii Rhizoma et Radix， and Saposhnikoviae Radix were grounded to fine powder， decocted with honey， and finally formed into pills with the size of a chicken head （1.5 g）. It was suggested that half a pill or one pill were taken for one dose with warm Lophatheri decoction and sugar. The indications and clinical application had developed from the recordings in Xiaoer Yaozheng Zhijue and evolved from pediatrics to ophthalmic otolaryngology， neurology， dermatology， digestion， and respiratory diseases. The main pathogenesis of these diseases is heat in the liver meridian and is treated. The effect of Xieqingwan is "clearing away heat and toxicity， removing fire and relaxing the bowels， and dispersing swelling and relieving pain". It is recommended to use the corresponding preparation methods in the 2020 Edition of Pharmacopoeia of the People's Republic of China. Modern clinical studies are centered around the clinical application of Xieqingwan， which is often modified and used in treating Tourette syndrome， herpes， febrile convulsion， sleepwalking， and insomnia. ConclusionThis paper conducts a thorough textual research of the key information of Xieqingwan， induces its historic evolution， and confirms its key information， so as to provide a reference for the future development of Xieqingwan.

ObjectiveTo analyze the quantity-quality transfer of standard decoction of Ginseng Radix et Rhizoma（GRR） decoction pieces produced by fresh and traditional cutting， and to provide reference for quality control and application development of the decoction pieces produced by fresh cutting. MethodTen batches of representative GRR decoction pieces produced by fresh and traditional cutting and their standard decoctions were prepared by standard process， and high performance liquid chromatography（HPLC） fingerprint of the standard decoction was established and performed on an Agilent EC-C₁₈ column（4.6 mm×150 mm， 2.7 μm） with acetonitrile（A）-0.1% phosphoric acid aqueous solution（B） as the mobile phase for gradient elution（0-23 min， 18%-21%A； 23-35 min， 21%-28%A； 35-80 min， 28%-32%A）， and the detection wavelength was 203 nm. Then similarity evaluation， principal component analysis（PCA） and partial least squares-discriminant analysis（PLS-DA） of fingerprint of the standard decoction were performed to screen the differential components with variable importance in the projection（VIP） value>1. Quantitative analysis was carried out on the screened known differential components， and combined with the indicators of the dry extract rate and the transfer rate， to explore the differences in the quantity-quality transfer between the standard decoction of GRR decoction pieces produced by fresh and traditional cutting. ResultThe fingerprint similarity of the standard decoction of GRR decoction pieces produced by fresh and traditional cutting was more than 0.950， and 18 common peaks were identified， including 9 identified common peaks. The results of PCA and PLS-DA showed that there were some differences in the contents of index components between the two standard decoctions. The contents of ginsenoside Rg₁， Re and Ro in GRR decoction pieces produced by fresh cutting were higher than those in traditional decoction pieces， while the contents of ginsenoside Rb₁， Rc ， Rb₂ and Rd were lower than those in traditional decoction pieces. The contents of ginsenoside Rg₁， Re， Rb₁ and Ro in the standard decoction of GRR decoction pieces produced by fresh cutting were higher than those in the standard decoction of traditional decoction pieces， while the contents of ginsenoside Rc ， Rb₂ and Rd were comparable between the two standard decoctions. Compared with the standard decoction of the traditional decoction pieces， the average transfer rates of ginsenoside Rg₁， Rb₁， Rc， Rb₂ and dry extract rate of the standard decoction of GRR decoction pieces produced by fresh cutting were significantly increased（P<0.05）， and the average transfer rate of ginsenoside Re and Rd also increased， but the difference was not statistically significant. ConclusionThe dry extract rate， content and transfer rate of index components of standard decoction of GRR decoction pieces produced by fresh cutting are better than those of the standard decoction of traditional decoction pieces， which can provides data support for the subsequent clinical application of fresh cutting products.

OBJECTIVE:To systematically evaluate the efficacy of rehabilitation exoskeleton robots on the lower limb motor function of stroke patients using Meta-analysis and to compare the efficacy of different lower limb exoskeleton robots,so as to provide a theoretical basis for the scientific selection of suitable exoskeleton robots for patients with post-stroke lower limb motor dysfunction. METHODS:Computer searches of the Cochrane Library,PubMed,Web of Science,Embase,CNKI,VIP,and WanFang Data were conducted to collect randomized controlled clinical studies on exploring lower extremity rehabilitation exoskeleton robots to improve lower limb motor function in stroke patients published from database inception to November 2022.Two researchers conducted the literature search and screening.The quality of the included literature was evaluated using the Cochrane 5.1.0 risk of bias assessment tool and the Jadad scale.Meta-analysis was performed using RevMan 5.4 and Stata 17.0 software. RESULTS:(1)Finally 22 publications were included,involving 865 patients(n=436 in the test group and n=429 in the control group),and the Jadad score showed that all the included articles were of high quality.(2)Meta-analysis results showed that the exoskeleton robot significantly improved the Fugl-Meyer Assessment of Lower Extremity score(mean difference[MD]=2.63,95%confidence interval[CI]:1.87-3.38,P<0.05),Berg Balance Scale score(MD=3.62,95%CI:1.21-6.03,P<0.05),Timed Up and Go score(MD=-2.77,95%CI:-4.48 to-1.05,P<0.05)and step frequency score(MD=3.15,95%CI:1.57-4.72,P<0.05)in stroke patients compared with the control group.However,there was no significant improvement in the Functional Ambulation Category Scale score(MD=0.30,95%CI:-0.01 to 0.61,P>0.05)and 6-minute walk test score(MD=3.77,95%CI:-6.60 to 14.14,P>0.05).(3)Network Meta-analysis results showed that compared with the conventional rehabilitation therapy,both the level-walking exoskeleton(MD=10.23,95%CI:3.81-27.49,P<0.05)and the body-weight support exoskeleton(MD=33.66,95%CI:11.49-98.54,P<0.05)improved the Fugl-Meyer Assessment of Lower Extremity score.Compared with the conventional rehabilitation therapy,body-weight support exoskeleton significantly improved the Berg Balance Scale scores(MD=79.86,95%CI:2.34-2 725.99,P<0.05).In terms of Fugl-Meyer Assessment of Lower Extremity and Berg Balance Scale scores,the ranking results were body-weight support exoskeleton>level-walking exoskeleton>conventional rehabilitation therapy.Compared with the conventional rehabilitation therapy,level-walking exoskeleton significantly improved the Functional Ambulation Category Scale score(MD=1.38,95%CI:1.00-1.90,P<0.05)and body-weight support exoskeleton significantly improved the Timed Up and Go score(MD=0.07,95%CI:0.01-0.51,P<0.05).In terms of Functional Ambulation Category Scale and Timed Up and Go scores,the ranking results were level-walking exoskeleton>body-weight support exoskeleton>conventional rehabilitation therapy. CONCLUSION:Rehabilitation exoskeleton robots can improve balance,walking and activities of daily living in stroke patients,with body-weight support exoskeleton being more effective in improving lower limb motor function and balance and level walking exoskeleton being more effective in improving functional walking and transfer.

Objective:To assess the clinical efficacy and infection control outcomes of two-stage revision in managing periprosthetic joint infection (PJI) following primary total knee arthroplasty (TKA) utilizing either a low or high constrained prosthesis.Methods:A retrospective analysis was performed on 40 patients who underwent revision TKA in the Sixth People's Hospital Affiliated to Shanghai Jiao Tong University from February 2019 to February 2022. According to the type of prosthesis selected in primary TKA, they were divided into low constrained prosthesis group and high constrained prosthesis group. There were 28 patients (28 knees) in the low constrained group, including 12 males and 16 females, aged 69.0(63.0, 74.0) years, with a body mass index of 25.18±0.55 kg/m 2. And there were 12 patients (12 knees) in the high-constrained group, including 5 males and 7 females, aged 66.5(65.0, 71.5) years, with a body mass index of 23.94±0.51 kg/m 2. All patients underwent two-stage revision surgery, with RHK used in 1 case and LCCK in 27 cases in the low-constrained prosthesis group. In the high-constrained prosthesis group, 3 patients were treated with RHK, 1 patient with PFC Sigma MBT, and 8 patients with LCCK. The preoperative and postoperative range of motion (ROM), Knee Society score (KSS), and postoperative infection control rate were compared between the two groups. Results:All patients were followed up. The follow-up time was 22.79±8.02 months in the low-constrained prosthesis group and 23.92±7.04 months in the high-constrained prosthesis group, with no significant difference between the two groups ( t=0.426, P=0.680). At the last follow-up, the KSS and ROM in the low-constrained prosthesis group were 77.96±9.74 and 93.48°±7.45°, respectively, significantly higher than 38.93±8.01 and 68.89°±9.44° before the operation ( P<0.05). The KSS score and ROM in the high-constrained prosthesis group were 67.83±8.31 and 80.08°±5.89° at the last follow-up, which were also significantly higher than those before operation (34.25±6.31 and 66.50°±10.48°, P<0.05). There was no significant difference in KSS and ROM between the two groups before operation ( P>0.05), but the KSS score and ROM in the low-constrained prosthesis group were significantly higher than those in the high-constrained prosthesis group at the last follow-up ( P<0.05). Bacterial culture results revealed that the primary infectious agents were coagulase-negative Staphylococcus and Staphylococcus aureus, with an overall infection control rate of 80% (32/40). The infection control rate was 89% (25/28) in the low-constrained prosthesis group and 58% (7/12) in the high-constrained prosthesis group, but the difference between the two groups was not statistically significant (χ 2=3.283, P=0.070). Conclusion:Two-stage revision effectively controls PJI, and the clinical outcomes of two-stage revision for PJI after primary TKA with a high-constrained prosthesis are inferior to those with a low-constrained prosthesis. Further exploration is needed to enhance efficacy.

Wilson disease（WD）is an inherited disorder caused by mutations in the ATP7B gene.It is characterized by pathological accumulation of copper in the organs throughout the body，especially the liver and brain. This article reviews the latest progress of existing and emerging therapies. At present，the most commonly used treatment methods are oral chelators of copper and zinc agents. Liver transplantation can be used as a treatment for end-stage patients. However，these treatment methods have some shortcomings：many side effects of drugs，poor treatment effect，lifelong treatment，poor patient compliance and so on. At present，the choice of drugs is still in the exploratory stage，and there are no guidelines to specify which patients should receive which treatment. In addition，there are many emerging therapies in different experimental stages，such as new chelators of copper，targeted molecular therapy，gene therapy and cell transplantation. The old methods have many disadvantages and lack large controlled clinical trials，and emerging research is still in its infancy，which are urgent questions.

As the foremost among the four examinations in traditional Chinese medicine （TCM）， inspection and related equipment research face challenges in landing and transformation due to variations in evidence quality， lack of standardization， insufficient algorithm transparency， and poor reliability and stability of decision-making. Against the backdrop of rapid development of emerging technologies such as big data， the internet of things， and artificial intelligence， coupled with macro policy support from the government， digital and intelligent generalized inspection in TCM has emerged， with the aim of utilizing digital technologies to overcome the limitations of naked-eye inspection and comprehensively perceive and analyze facial and bodily expressions. The research in this field intelligently correlates Zang-fu organ functions with health conditions and disease progression and establishes a technical system for digital and intelligent inspection， multi-dimensional and multimodal perception， fusion analysis， and decision-making. This system aims to enhance the accuracy of disease risk warning and diagnosis， bridging the gap between inspection equipment and assistance in clinical decision-making. From an evidence-based perspective， this paper systematically examines the research ideas of digital and intelligent inspection and the development of related equipment， deeply explores how to propose clinical practice-oriented key scientific issues， comprehensively acquire and co-apply multi-dimensional data， establish precise inspection models driven by digital intelligence， optimize standards to enhance equipment interoperability and reliability， construct post-effect evaluation mechanisms to promote improvement， and actively address potential risks such as the black box nature and information security in the application of intelligent technology. This paper not only demonstrates the tremendous potential of digital technologies in improving the accuracy and clinical application efficiency of inspection but also provides new perspectives and ideas for the modernization of inspection in TCM， paving the way for the application of inspection in the global medical and health field.

Objective To study the mechanism of the treatment of metabolism associated steatohepatitis(MASH)in rats with Xiaoyao Wan.Methods Twenty-four SD male rats were randomly divided into control group(CON group,n=8)and model group(n=8).The model group was given high-fat diet,carbon tetrachloride(CCl4)subcutaneous injection,hunger and satiety disorder and tail clamping for four weeks to establish the MASH model,and the rats were randomly divided into the MOD group and the Xiaoyao Wan group(XYW group),with 8 rats in each group.The rats of the XYW group were given Xiaoyao Wan,the other two groups were given normal saline.Four weeks after administration,the serum biochemical indexes and oxidative stress indexes of rats in different groups were detected.The pathological sections of rat liver tissue were observed by hematoxylin-eosin(HE)stai-ning and oil red O staining.The expression of cytochrome P450 2E1(CYP2E1),factor-related apoptosis ligand(FasL),tumor necrosis factor-α(TNF-α)and tumor growth factor-β1(TGF-β1)in rat liver were detected by Western blot method.The relative contents of CYP2E1,FasL,TNF-α and TGF-β1 mRNA in liver tissue were de-tected by RT-qPCR.Results The general condition of rats in the XYW group was significantly improved compared with the MOD group;the level of hepatic index was significant decrease compared with the MOD group(P＜0.01)and the level of body mass index was significant increase compared with the MOD group(P＜0.01);the serum levels of triglyceride,total cholesterol,low-density lipoprotein cholesterol,aspartate aminotransferase,alanine aminotransferase,malondialdehyde,monocyte chemotactic protein-1,TNF-α,and interleukin(IL)-18 were signif-icantly reduced compared with the MOD group(all P＜0.05),and the levels of high-density lipoprotein choles-terol,superoxide dismutase,and IL-10 were significantly elevated compared with the MOD group(all P＜0.05);the content of lipid droplets in hepatocytes of rats was significantly reduced compared with the MOD group under light microscope;the protein levels of CYP2E1,FasL,TNF-α and TGF-β1 in liver tissues were significantly re-duced compared with the MOD group(all P＜0.05),and the relative contents of CYP2E1,FasL,TNF-α and TGF-β1 mRNA were significantly reduced compared with the MOD group(all P＜0.05).Conclusion Xiaoyao Wan can regulate the expression of CYP2E1,FasL,TNF-α and TGF-β1 in the liver tissue of MASH rats by reduc-ing the accumulation of fat in the liver,so as to achieve the purpose of treating MASH.

Objective:To investigate the status quo and influencing factors of social isolation of parents of children with autism spectrum disorder in order to provide theoretical basis for clinical intervention measures.Methods:A total of 340 parents of children with autism spectrum disorder who visited the Children′s Developmental Behavior Center of Third Affiliated Hospital of Sun Yat sen University were selected by the convenience sampling method as research objects during July to November 2023. A cross-sectional survey was investigated by a general information questionnaire, General Alienation Scale, Social Avoidance and Distress Scale, Affiliate Stigma Scale, Family APGAR Index, Chinese Simplified Version of Social Support Scale, and Social Responsiveness Scale.Results:A total of 323 valid questionnaires were collected, including 235 mothers and 88 fathers; 33 individuals aged 25-29 years, 233 individuals aged 30-39 years, and 57 individuals aged 40-60 years. The subjective social isolation score of parents of children with autism spectrum disorder was 33.24 ± 4.92 and the objective social isolation score was 4.00(2.00,7.00). The results of multiple linear regression analysis showed that the subjective social isolation of parents of children with autism spectrum disorder was influenced by factors including self-assessed health status, whether they worked full-time or not, whether they were satisfied with the division of labor in the family caring for their children, affiliate stigma, family care, and social support (all P<0.05); and the objective social isolation of parents was influenced by factors including the severity of autism symptoms, self-assessed health status, affiliate stigma, and family care (all p<0.05). Conclusions:Parents of children with autism spectrum disorder had some degree of social isolation, and the level of subjective social isolation was higher than objective social isolation. Healthcare professionals should pay attention to parents of autistic children who have high levels of symptom severity, poor self-rated health, do not work full-time, and are dissatisfied with the division of labor in the family caring for their child, and take measures to reduce the affiliate stigma, and to increase the level of family care and social support, so as to improve the social isolation of parents of children with autism spectrum disorder.
