ABSTRACT
ObjectiveTo explore the mechanism of Buzhong Yiqitang on pyroptosis in autoimmune thyroiditis （AIT） mice based on the NOD-like receptor hot protein domain related protein 3 （NLRP3）/cysteinyl aspartate specific proteinase-1（Caspase-1）/Gasdermin D （GSDMD） pathway. MethodSixty NOD.H-2h4 mice were divided into normal group， model group， low， medium， and high dose groups （4.10， 8.19， 16.38 g·kg-1）of Buzhong Yiqitang， and selenium yeast tablet group （0.26 mg·kg-1）， with 10 mice in each group. Except for the normal group， all other groups were given 0.05% NaI by gavage for eight weeks to establish a model and then received the drug treatment for eight weeks. The serum levels of thyroid peroxidase antibody （TPO-Ab） and thyroglobulin antibody （TgAb） were detected using enzyme-linked immunosorbent assay （ELISA） method. Hematoxylin-eosin （HE） staining was used to observe the pathological changes in mouse thyroid tissue. The immunohistochemical method was used to detect the protein expression of NLRP3， Caspase-1， interleukin-1β （IL-1β）， and interleukin-18 （IL-18）. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression of NLRP3， Caspase-1， IL-1β， and IL-18. Western blot was used to detect the levels of pyroptosis-related proteins in thyroid tissue. ResultCompared with the normal group， the serum levels of TPO-Ab and TgAb in the model group were significantly increased （P<0.01）. Thyroid follicles either increased in a cubic shape or were damaged and atrophied， with a large number of lymphocytes infiltrating around the follicles. Compared with the model group， the levels of TPO-Ab and TgAb in other groups were significantly reduced （P<0.01）， and the morphology and structure of follicles were improved. The degree of lymphocyte infiltration was reduced. Among them， the medium dose group of Buzhong Yiqitang had the most significant reduction and improvement effect. Compared with the normal group， the positive products and mRNA expression of NLRP3， Caspase-1， IL-1β， and IL-18 proteins in the thyroid tissue of the model group significantly increased （P<0.01）， and the protein expression levels of NLRP3， cleaved Caspase-1， IL-1β， IL-18， and GSDMD-N were significantly increased （P<0.05， P<0.01）. Compared with the model group， the positive products and mRNA expression of NLRP3， Caspase-1， IL-1β， and IL-18 proteins in other groups were significantly reduced （P<0.05， P<0.01）， with the most significant reduction effect in the medium dose group of Buzhong Yiqitang. The protein expression levels of NLRP3， cleaved Caspase-1， IL-1β， IL-18， and GSDMD-N were significantly reduced （P<0.05， P<0.01）. ConclusionBuzhong Yiqitang can improve AIT， and its mechanism may be achieved by regulating the NLRP3/Caspase-1/GSDMD signaling pathway to inhibit pyroptosis.

ABSTRACT
As people's living standards improve， the development trend of diabetes has gradually become severe. Diabetes is a chronic inflammatory disease associated with abnormal expression of nuclear factor-kappa B （NF-κB） in patients. NF-κB exists in various tissue cells and participates in the regulation of a variety of genes related to immune function and inflammation. Varieties of factors can activate NF-κB when the body is stimulated by external factors， so as to produce inflammation and other reactions. Previous studies on NF-κB mainly focus on cancer， and the pathological mechanism of the treatment of diabetes by related signaling pathways and the progress of traditional Chinese medicine （TCM） treatment have not been systematically elaborated on. By referring to the relevant literature in China and abroad， it was found that NF-κB is not isolated in the development and progression of diabetes but is associated with signal molecules related to inflammation， oxidative stress， and energy metabolism， and it is involved in mediating inflammation， pancreatic β cell apoptosis， insulin signal transduction， and other physiological functions. Therefore， blocking the transmission of NF-κB signaling pathway is beneficial to the treatment of diabetes. At present， Western medicine for the treatment of diabetes mainly includes oral hypoglycemic drugs and insulin injections， but the adverse reactions are obvious. TCM has been characterized by multi-target， extensive action， and excellent curative effects in the treatment of diabetes. TCM and its compounds with functions of tonifying Qi and promoting blood circulation， regulating qi and eliminating phlegm， clearing heat and detoxifying， and nourishing Yin and moistening dryness can effectively intervene in the abnormal expression of NF-κB signaling pathway in vivo through anti-inflammatory effects. In this paper， the association between NF-κB signaling pathway and diabetes was summarized， and the modern research progress of TCM intervention of NF-κB signaling pathway in the treatment of diabetes in the past five years was reviewed， so as to lay a laboratory foundation for the study of a new pathological mechanism of diabetes based on NF-κB signaling pathway and provide new targets and research direction for the prevention and treatment of diabetes and development of related TCM.
ABSTRACT
Sepsis is a condition characterized by organ dysfunction resulting from the systemic inflammatory response triggered by an infection. Excessive inflammation and immunosuppression are intertwined, and severe cases may even develop into multiple organ failure. Studies have shown that indoleamine 2,3-dioxygenase 1-mediated tryptophan metabolism is involved in the occurrence and development of sepsis, and elevated plasma kynurenine levels and Kyn/Trp ratios are early indicators of sepsis development. In this paper, we provide a comprehensive summary of the role of IDO1 in the acute inflammatory phase of sepsis, late immunosuppression, and organ damage. This includes its regulation of inflammatory state, immune cell function, blood pressure, and other aspects. Additionally, we analyze preclinical studies on targeted IDO1 drugs. An in-depth understanding and study of IDO may help to understand the pathogenesis and clinical significance of sepsis and multiple organ damage from a new perspective and provide new research ideas for exploring its prevention and treatment methods.
ABSTRACT
Objective To observe the clinical efficacy of Shen Shuai Ⅱ Granules combined with integrated Western medicine therapy in patients with primary chronic kidney disease(CKD)in stages 3-4 with the syndrome of spleen and kidney qi deficiency,dampness turbidity and blood stasis,and its effects on expression of serum autophagy related proteins.Methods Totally 88 patients were randomly divided into treatment group and control group,with 44 cases in each group.Both groups were given an integrated Western medicine therapy.On this basis,the treatment group was given Shen Shuai Ⅱ Granules,while the control group was given Shen Shuai Ⅱ placebo,1 bag at a time,twice a day,orally.The treatment for both groups lasted for 24 weeks.The clinical efficacy of the two groups was observed.The TCM symptom scores,serum creatinine(Scr),blood urea nitrogen(BUN),uric acid(UA),blood calcium(Ca2+),blood phosphorus(P3-),parathyroid hormone(PTH),and 24-hour urinary protein quantification(24 UPro)before and after treatment were compared in the two groups.The serum levels of autophagy related protein Beclin-1,Atg7,and LC3-Ⅱ were detected by ELISA before and after treatment in the two groups.Safety indexes of both groups were monitored.Results During the treatment,4 cases fell off in the treatment group and 4 cases in the control group.The total effective rate in the treatment group was 55％(22/40),while that in the control group was 30％(12/40).The therapeutic effect in the treatment group was better than that in the control group(P<0.01).Compared with before treatment,the TCM symptom scores in the treatment group decreased after treatment(P<0.01),the levels of Scr,BUN,UA,P3-,PTH,and 24 UPro decreased(P<0.05,P<0.01),while eGFR increased(P<0.01).The levels of Scr in the control group increased(P<0.05),while eGFR decreased(P<0.01).After treatment,the treatment group had lower various TCM symptom scores,Scr,BUN,UA,P3-,PTH,and 24 UPro levels than the control group(P<0.01,P<0.05),and higher eGFR than the control group(P<0.01).Compared with before treatment,the serum levels of Beclin-1,Atg7,and LC3-Ⅱ increased in the treatment group after treatment(P<0.01,P<0.05),while the serum level of Beclin-1 decreased in the control group after treatment(P<0.01).After treatment,the improvement of the above indicators in the treatment group were better than those in the control group(P<0.01,P<0.05).Correlation analysis showed that Beclin-1,Atg7,and LC3-Ⅱ were negatively correlated with Scr and BUN(P<0.05),and positively correlated with eGFR(P<0.05).There was no obvious adverse reaction in both groups.Conclusion The combination of Shen Shuai Ⅱ Granules and integrated Western medicine therapy for the treatment of primary CKD in stages 3-4 with the syndrome of spleen and kidney qi deficiency,dampness turbidity and blood stasis has confirmed efficacy,which can effectively alleviate clinical symptoms,improve renal function,and delay the progression of CKD.The mechanism may be related to improving the level of autophagy in renal.
ABSTRACT
Objective:To explore the biomechanical stability of a novel anchor-loop internal fixation system in the treatment of acromioclavicular joint dislocation using cadaveric specimens.Methods:The acromioclavicular ligaments were severed in 12 complete shoulder joint specimens, in which the quasi-static non-destructive cycle experiment was performed until the coracoclavicular ligaments failed. The failure intensities of the coracoclavicular ligaments were recorded. Next, the 12 specimens were randomly divided into groups A, B, C and D ( n=3), in which 4 different internal fixation materials were used respectively to reduce and fix the acromioclavicular joint. Group A was subjected to 3.5 mm clavicular hook locking compression plate, group B to 5 mm soft tissue with wire anchor, group C to 10 mm Endobutton steel plate, and group D to the novel anchor-loop internal fixation system (5 mm soft tissue with wire anchor + 10 mm Endobutton steel plate). An X-ray machine was used to evaluate the reduction and internal fixation of the acromioclavicular joint. After the shoulder specimens were securely fastened by a homemade fixation jig to a 100 KN electronic universal mechanical testing machine, each experimental specimen was subjected to a destructive static tensile mechanic determination in the vertical direction at a loading speed of 100 mm/min. The load-displacement curves were recorded and drawn by a computer connected with the biomechanical testing machine. The failure strength and failure causes were recorded for each internal fixation. Results:The fracture strength of the coracoclavicular ligament in 12 cadaver specimens was (374.6±0.8) N. The mechanical load of internal fixation failure was (409.5±2.6) N in group A, (297.8±3.4) N in group B, (375.2±3.1) N in group C and (376.2±3.1) N in group D. The internal fixation failure was due to clavicular fracture in 2 specimens and to acromial fracture in 1 specimen in group A, to anchor protrusion in all the 3 specimens in group B, to coracoid base fracture in all the 3 specimens in group C, and to anchor protrusion in all the 3 specimens in group D. The mechanical loads of internal fixation failure were significantly different among the 4 experimental groups ( P<0.05). The mechanical load of internal fixation failure in group D was significantly different from that in groups A and B ( P<0.05). Conclusions:Our self-developed novel anchor-loop internal fixation system can effectively reposit the acromioclavicular joint to treat acromioclavicular joint dislocation, because it conforms to the biomechanical characteristics of the acromioclavicular joint, and is easy to handle. Therefore, its feasibility is high.
ABSTRACT
Objective:To compare the clinical data and peripheral blood levels of CXC chemokine ligand (CXCL) 9 and CXCL10 between patients with progressive non-segmental vitiligo who were sensitive to systemic glucocorticoid treatment and those who were resistant, and to clarify key clinical factors influencing the sensitivity to systemic glucocorticoid treatment.Methods:From May 2021 to May 2023, a cohort of patients with progressive non-segmental vitiligo receiving systemic glucocorticoid treatment was established in Huashan Hospital, Fudan University. Clinical data and peripheral blood samples were prospectively collected from all enrolled patients. Standard treatment, i.e., intramuscular injections of 1 ml of compound betamethasone once a month, was administered. After 3-month treatment, the improvement of patients′ skin lesions was estimated, and the vitiligo area and severity index (VASI) score and the Vitiligo European Task Force assessment tool (VETFa) were used to evaluate the efficacy. Patients with VASI changes ≥ 0 and VETFa progression scores ≤ 0 point were included in the glucocorticoid-sensitive group (i.e., the patients′ condition was stable or improved), otherwise those with VASI changes < 0 and VETFa progression scores of 1 point were included in the glucocorticoid-resistant group. Associations of lesion locations, specific clinical markers (trichrome lesions, confetti-like depigmentation, and Koebner phenomenon), previous medication history, family history of vitiligo, etc. with the response to systemic glucocorticoid treatment were analyzed. At baseline and after 3-month treatment, peripheral blood samples were collected from the patients, and enzyme-linked immunosorbent assay was performed to detect the plasma levels of CXCL9 and CXCL10. Statistical analysis was carried out by using the chi-square test, Fisher′s exact test, binary logistic regression analysis, Mann-Whitney U test, and Wilcoxon signed-rank test. Results:A total of 142 patients with vitiligo were enrolled, and 127 completed 3-month treatment, including 77 males and 50 females. Their age at diagnosis was 18 to 65 (36.6 ± 11.4) years, and the disease duration ranged from 2 months to 58 (13.5 ± 10.7) years; 25 (19.7%) had a family history of vitiligo; the percentage of lesion area to total body surface area before treatment ranged from 1% to 70% (11.5% ± 12.7%), and the VASI score was 1% to 70% (10.8% ± 11.6%). Multivariate logistic regression analysis showed that the absence of specific clinical markers (odds ratio [ OR] = 6.900, 95% confidence interval [ CI]: 1.228, 38.757, P = 0.028), carrying a single specific clinical marker ( OR = 2.579, 95% CI: 1.012, 6.574, P = 0.047), having a history of topical glucocorticoid treatment ( OR = 2.643, 95% CI: 1.019, 6.850, P = 0.041), the absence of family history of vitiligo ( OR = 5.090, 95% CI: 1.070, 24.215, P = 0.030), and lesions on the proximal extremities ( OR = 3.767, 95% CI: 1.315, 10.793, P = 0.037) were risk factors for the resistance to systemic glucocorticoid treatment in the patients with vitiligo. After 3-month treatment, the glucocorticoid-sensitive group showed a significant decrease in plasma CXCL10 levels compared with those before treatment ( W = 571.00, P < 0.001), while there was no significant difference between the pre- and post-treatment CXCL10 levels in the glucocorticoid-resistant group ( W = 48.00, P = 0.524). Additionally, no significant difference was observed in changes of the plasma CXCL9 level before and after treatment between the glucocorticoid-sensitive and glucocorticoid-resistant groups ( P > 0.05) . Conclusions:Carrying no or a single specific clinical marker, having a history of topical glucocorticoid treatment, the absence of family history of vitiligo, and lesions on the proximal extremities appeared to be risk factors for the resistance to systemic glucocorticoid treatment in patients with progressive non-segmental vitiligo. Changes in CXCL10 levels after treatment may be used as an important evaluation indicator for determining whether patients with progressive vitiligo were resistant to systemic glucocorticoid treatment.
ABSTRACT
Ulcerative colitis (UC) is a chronic inflammation of the gastrointestinal tract and is characterized by alternating periods of inflammation and remission. Although UC incidence is lower in Taiwan than in Western countries, its impact remains considerable, demanding updated guidelines for addressing local healthcare challenges and patient needs. The revised guidelines employ international standards and recent research, emphasizing practical implementation within the Taiwanese healthcare system. Since the inception of the guidelines in 2017, the Taiwan Society of Inflammatory Bowel Disease has acknowledged the need for ongoing revisions to incorporate emerging therapeutic options and evolving disease management practices. This updated guideline aims to align UC management with local contexts, ensuring comprehensive and context-specific recommendations, thereby raising the standard of care for UC patients in Taiwan. By adapting and optimizing international protocols for local relevance, these efforts seek to enhance health outcomes for patients with UC.
ABSTRACT
Crohn’s disease (CD) is a chronic, fluctuating inflammatory condition that primarily affects the gastrointestinal tract. Although the incidence of CD in Taiwan is lower than that in Western countries, the severity of CD presentation appears to be similar between Asia and the West. This observation indicates the urgency for devising revised guidelines tailored to the unique reimbursement system, and patient requirements in Taiwan. The core objectives of these updated guidelines include the updated treatment choices and the integration of the treat-to-target strategy into CD management, promoting the achievement of deep remission to mitigate complications and enhance the overall quality of life. Given the diversity in disease prevalence, severity, insurance policies, and access to medical treatments in Taiwan, a customized approach is imperative for formulating these guidelines. Such tailored strategies ensure that international standards are not only adapted but also optimized to local contexts. Since the inception of its initial guidelines in 2017, the Taiwan Society of Inflammatory Bowel Disease (TSIBD) has acknowledged the importance of continuous revisions for incorporating new therapeutic options and evolving disease management practices. The latest update leverages international standards and recent research findings focused on practical implementation within the Taiwanese healthcare system.
ABSTRACT
Objective@#Patients with late life depression sometimes refuse to receive electroconvulsive therapy (ECT) owing to its adverse reactions. To alleviate patient’s resistance, a novel ECT stimulation strategy named mixed-strategy ECT (msECT) was designed in which patients are administered conventional ECT during the first three sessions, followed by low energy stimulation during the subsequent sessions. However, whether low energy electrical stimulation in the subsequent stage of therapy affect its efficacy and reduce adverse reactions in patients with late life depression remains unknown. To explore differences between msECT and regular ECT(RECT) with respect to clinical efficacy and side effects @*Methods@#This randomized, controlled trial was conducted from 2019 to 2021 on 60 patients with late life depression who were randomly assigned to two groups: RECT or msECT. A generalized estimating equation (GEE) was used to compare the two stimulation strategies regarding their efficacy and side effects on cognition. Chi-squared test was used to compare side effects in the two strategies. @*Results@#In the intent-to-treat group, the GEE model suggested no differences between-group difference in Hamilton Depression Rating Scale-17 score over time (Wald χ2=7.275, p=0.064), whereas the comparison of side effects in the two strategies favored msECT (Wald χ2=8.463, p=0.015) as fewer patients had adverse events during the second phase of treatment with msECT (χ2 =13.467, p=0.004). @*Conclusion@#msECT presents its similar efficacy to RECT. msECT may have milder side effects on cognition.

ABSTRACT
ObjectiveTo investigate the protective effect of Geju Hugan tablets on the liver of mice with alcohol-induced liver injury， and explore the underlying mechanism based on nuclear factor-κB p65 （NF-κB p65） and B-cell lymphoma-2 （Bcl-2）/Bcl-2-associated X protein （Bax） signaling pathways. MethodAccording to the body weight， 60 SPF-grade male ICR mice were randomized into normal， model， Compound Yiganling tablets （0.16 g·kg-1）， and low-， medium-， and high-dose （0.2， 0.4， 0.8 g·kg-1， respectively） Geju Hugan tablets groups. The drugs were administrated at the corresponding doses by gavage， and the normal and model groups with equal volume of pure water once a day for 28 consecutive days. On day 29， the mice in other groups except the normal group were administrated with liquor （53% Vol） by gavage twice a day at the doses of 20， 10 mL·kg-1 and with the interval of 6 h. Samples were harvested on day 30. The histopathological changes in the liver were observed by hematoxylin-eosin （HE） staining， and the ultrastructural changes in hepatocytes were observed by transmission electron microscopy. The enzyme-linked immunosorbent assay was employed to measure the levels of malonaldehyde （MDA）， reduced glutathione （GSH）， and triglycerides （TG） in the liver tissue and the levels of alanine aminotransferase （ALT） and aspartate aminotransferase （AST） in the serum. Western blotting was employed to determine the protein levels of NF-κB p65， phosphorylated p-inhibitor kappa B alpha （p-IκBα）， Bcl-2， and Bax in the liver tissue. ResultCompared with the normal group， the model group showed increases in the ALT， AST， MDA， and TG levels， a decrease in the GSH level， and increases in the liver injury scores evaluated based on the HE， oil red O， and transmission electron microscopy （P<0.01）. Moreover， the model group showed up-regulated expression of NF-κB， p-IκBα， and Bax （P<0.05， P<0.01） and down-regulated expression of Bcl-2 （P<0.05） in the liver tissue. Compared with the model group， Geju Hugan tablets of all the doses lowered the ALT， AST， MDA， and TG levels and elevated the GSH level （P<0.01）. The liver injury scores assessed based on HE staining and transmission electron microscopy in the medium- and high-dose Geju Hugan tablets groups were lower than those in the model group （P<0.01）. Compared with the model group， medium- and high-dose Geju Hugan tablets down-regulated the protein levels of NF-κB， p-IκBα， and Bax （P<0.01） and all doses of Geju Hugan tablets up-regulated the protein level of Bcl-2 （P<0.01）. ConclusionGeju Hugan tablets protect mice from alcohol-induced liver injury by down-regulating NF-κB signaling pathway to alleviate inflammation in the liver tissue and down-regulating the expression of Bax and up-regulating the expression of Bcl-2 to inhibit hepatocyte apoptosis.

ObjectiveTo investigate the effect of rutin on the browning of 3T3-L1 preadipocytes and the mechanism. MethodCell counting kit-8 （CCK-8） assay was used to detect the effect of different concentration of rutin （3.125， 6.25， 12.5， 25， 50， 100， 200 μmol·L-1） on 3T3-L1 cell activity， and Western blot to examine the effect of rutin （12.5， 25， 50 μmol·L-1） on the expression of thermogenesis-associated proteins uncoupling protein 1 （UCP1）， PR domain containing 16 （PRDM16） and peroxisome proliferator-activated receptor γ coactivator-1α （PGC-1α） in adipocytes. After the optimal concentration of rutin was determined， the effect of rutin on lipid droplet formation in adipocytes was observed based on oil red O staining， and the expression of nuclear respiratory factor 1 （NRF1）， nuclear respiratory factor 2 （NRF2） and mitochondrial transcription factor A （TFAM）， which were the landmark proteins of mitochondrial biosynthesis， was detected by Western blot. ResultCompared with the blank group， 200 μmol·L-1 rutin inhibited 3T3-L1 cell activity （P<0.01）. Compared with the blank group， at the concentration of 12.5， 25， 50 μmol·L-1 rutin significantly promoted the expression of thermogenesis-associated proteins （UCP1， PRDM16， and PGC-1α） （P<0.01）， which was determined as the optimal concentration. Compared with the blank group， 50 μmol·L-1 rutin significantly increased the immunofluorescence intensity of mitochondrial UCP1 protein in 3T3-L1 cells （P<0.01） and the expression of the markers of mitochondrial biosynthesis （NRF1， NRF2， and TFAM） （P<0.01）. In addition， 50 μmol·L-1 rutin significantly inhibited lipid droplet formation of 3T3-L1 adipocytes （P<0.01）. ConclusionRutin inhibited lipid droplet deposition in 3T3-L1 adipocytes and increased the expression of thermogenesis-related proteins （UCP1， PRDM16， and PGC-1α） and markers of mitochondrial biosynthesis （NRF1， NRF2， and TFAM）， thereby inducing the browning of 3T3-L1 adipocytes. This lays a basis for the development of drugs that safely regulate the browning of white cells.
ABSTRACT
AIM: To compare the efficacy of and without small incision lenticule extraction(SMILE)with cyclotorsion compensation for astigmatism correction.METHODS: PubMed, Web of Science, EMBASE, Cochrane and CNKI, VIP, CBM, and Wan Fang Data were searched for clinically controlled studies from January 2010 to August 2022, including an experimental group with cyclotorsion compensation during SMILE and a control group without cyclotorsion compensation during SMILE. After literature screening, quality evaluation, and data extraction by two researchers independently, the Meta-analysis of uncorrected distance visual acuity(UDVA), residual astigmatism, vector analysis indicators for measuring the astigmatism correction including absolute value of angle of error(|AE|)and magnitude error(ME), and post-operative total higher order aberrations, spherical aberration and coma was carried out with Stata 16.0 software.RESULTS: Seven studies with a total of 846 eyes(442 in the experimental group, 404 in the control group)were finally included. The Meta-analysis showed that there were significant differences in the percentage of eyes with residual astigmatism ≥1.00D(OR=0.17, 95%CI: 0.06～0.49, P<0.01), |AE|(WMD=-1.56, 95%CI: -2.68～-0.45, P<0.01), the coma(WMD=0.06, 95%CI: -0.08～-0.04, P<0.01), and the total higher order aberrations(WMD=-0.04, 95%CI: -0.06～-0.02, P<0.01). However, there were no differences in the postoperative UDVA(WMD=0.00, 95%CI: -0.02～0.01, P=0.54), residual astigmatism(WMD=0.08, 95%CI: -0.02～0.18, P=0.10), ME(WMD=-0.01, 95%CI: -0.14～0.12, P=0.85), and the spherical aberration(WMD=0.03, 95%CI: -0.07～0.13, P=0.52).CONCLUSION: Cyclotorsion compensation in SMILE can reduce the angular error caused by eye rotation during astigmatism correction. It also decreases postoperative residual astigmatism. Overall, the SMILE with cyclotorsion compensation is superior in clinical efficacy of the precise correction of astigmatism.
ABSTRACT
@#Chimeric antigen receptor T-cell (CAR-T) immunotherapy has made a breakthrough in the clinical treatment of a variety of hematological tumors.However, the CAR-T cell products listed at China and abroad are all autologous CAR-T.Compared with autologous CAR-T treatment, universal CAR-T exhibits significant advantages, which could fulfill the treatment demand of more patients, but also displays high technical barriers.This paper reviews the universal CAR-T, clearly points out the two major challenges faced by the development of universal CAR-T, and then summarizes and analyzes the feasible solutions according to the mechanism causing the two major problems.This paper also summarizes domestic and foreign companies producing universal CAR-T and the latest clinical progress of their superior products, and then discusses the feasibility of the development strategy from another aspect, in order to provide ideas for developing a new generation of universal CAR-T cell therapy products.
ABSTRACT
Neuropathic pain is a clinical symptom with complex mechanisms and high incidence. The commonly used analgesics have limited efficacy and can cause serious side effects. The theory of chronic pain entering collaterals was proposed by YE Tianshi， a famous physician focusing on warm diseases in the Qing dynasty， on the basis of the ancient therapies for pain. This theory is particularly suitable for the diagnosis and treatment of neuropathic pain in view of the clinical course and manifestations. The chronic neuropathic pain can enter the Yin collateral in deeper sites. The pathogenesis of neuropathic pain is summarized as a deficiency in origin and excess in superficiality. The root cause is the dysfunction of Zang-Fu organs， mainly the liver, kidney and heart， while the superficial causes are phlegm and stasis caused by the obstructed Qi and blood movement due to the consumption of Qi and blood in collaterals. Accordingly， the therapies such as dispelling blood stasis， resolving phlegm， and dredging collaterals should be adopted. This paper expounds the traditional Chinese medicine （TCM） pathogenesis and treatment of neuropathic pain， enriching the knowledge and providing new ideas for the TCM prevention and treatment of this disease as a collateral disease.
