To systematically review randomized controlled trials （RCTs） of traditional Chinese medicine （TCM） intervention in ulcerative colitis （UC）， and analyze the characteristics of these studies and their outcome indicators， thereby providing references for the design of future RCTs of TCM intervention in UC and offering evidence supporting the clinical application of TCM in UC. A computerized search was conducted in the China National Knowledge Infrastructure （CNKI）， Wanfang Data， VIP， SinoMed， PubMed， Cochrane Library， EMbase， and Web of Science databases for RCTs of TCM intervention in UC published from January 2021 to August 2024. The risk of bias was assessed， and outcome indicators were qualitatively analyzed. A total of 555 RCTs were included， with a sample size of 44 853 participants. The largest sample size was 218 cases， and the smallest was 28 cases， with most studies focusing on 60-100 participants. Of the 386 RCTs that explicitly reported TCM syndrome types， the top three were large intestine dampness-heat syndrome （31.05%）， spleen and kidney yang deficiency syndrome （12.47%）， and spleen deficiency with dampness syndrome （9.17%）. The interventions， ranked by frequency of use， included internal Chinese medicine compounds/preparations （64.5%）， Chinese medicine compounds/preparations with retained enema （18.2%）， internal Chinese medicine compounds/preparations + external TCM treatment （5.95%）， and external TCM treatment alone （4.86%）. The treatment duration was mainly 4-8 weeks （64.86%）， with 61 studies （10.99%） reporting follow-up time. A total of 157 outcome indicators were used， with a frequency of 3 460 occurrences， classified into six domains： TCM syndromes and symptoms （346 occurrences， 10%）， symptoms/signs （541 occurrences， 15.64%）， physical and chemical examinations （2 119 occurrences， 61.24%）， quality of life （107 occurrences， 3.09%）， long-term prognosis （61 occurrences， 1.76%）， and safety events （284 occurrences， 8.21%）. The analysis reveals several limitations in the outcome indicators of TCM intervention in UC， including the lack of a basis for sample size calculation， non-standardized TCM syndrome classification， absence of trial design and registration， inadequate blinding and allocation concealment， adherence issues with interventions， imbalanced selection of surrogate and endpoint indicators， inconsistency in the timing of outcome measurements， design issues that require standardization， and ethical and safety concerns. It is recommended that future studies actively construct a set of core indicators for UC that include standardized TCM syndrome classification， clear efficacy evaluation indicators， key endpoint indicators， and reasonable measurement time points. Long-term prognostic impacts， comprehensive assessments of patients' quality of life， and consideration of economic benefits should be emphasized， providing a basis for the clinical practice of TCM in the treatment of UC.

Asthma is a chronic inflammatory respiratory disease involving multiple cells and cellular components， characterized by recurrent episodes of wheezing， shortness of breath， chest tightness， and coughing， significantly impacting patients' quality of life. The phosphatidylinositol 3-kinase/protein kinase B（PI3K/Akt） signaling pathway， as a crucial hub in intracellular signaling， is widely involved in the regulation of cell growth， proliferation， survival， metabolism， and a series of pathophysiological processes. Its regulatory role in the pathological progression of asthma is particularly significant， specifically in promoting airway inflammation， mediating epithelial mesenchymal transition， accelerating airway remodeling， regulating cell autophagy， inducing mucus hypersecretion， and influencing immune response balance. This study analyzed potential molecular targets of the PI3K/Akt pathway， including activators such as cysteine proteinase inhibitor 1（CST1）， found in inflammatory zone 1（FIZZ1） and free fatty acid receptor 1（FFAR1）， and inhibitors such as human β-defensin-3（hBD-3）， disintegrins， metalloproteinase 33（ADAM33） and interleukin-27（IL-27）， and initially revealed the potential molecular mechanisms of traditional Chinese medicine（TCM） in asthma intervention. Based on this， the authors systematically summarized the efficacy and specific mechanisms of TCM monomers， compounds， and external treatments for asthma by regulating the PI3K/Akt signaling pathway through literature review and analysis， aiming at establishing a robust foundation for the wide application and advanced development of TCM in asthma treatment， offering innovative insights for clinical research and drug development of asthma.

Phantom limb pain (PLP) is a form of neuropathic pain occurring after limb amputation, and its underlying mechanisms remain unclear, posing significant challenges for clinical management. Spinal cord stimulation (SCS), a neuromodulation technique, has shown potential in relieving chronic pain, though its long-term efficacy and safety in treating PLP require further validation. This report presents a case of a 42-year-old male experiencing persistent radiating, lightning-like pain [Visual Analog Scale (VAS) score 8-9], following right upper limb amputation. Preoperative imaging revealed signal loss in the right nerve roots at C₆-T₁. A percutaneous electrode was implanted surgically to achieve full coverage of the painful region. Five days postoperatively, the VAS score dropped to 2-3, and after 1 year of follow-up, the patient continued to experience significant pain relief (VAS 1-2), with complete resolution of depressive symptoms and cessation of analgesic medication. Existing studies suggest that the long-term outcomes of SCS may fluctuate, and attention should be paid to potential complications such as infection and electrode displacement.

Objective To investigate the key elements for model establishment and determine the evaluation indicators of animal models for pelvic inflammatory disease(PID),providing a reference for improving modelling methods and optimizing the application of PID animal models.Methods The search query"Pelvic Inflammatory Disease"AND"Animal Model"OR"Rat"OR"Mouse"OR"Guinea Pig"OR"Rabbit"OR"Dog"OR"Pig"was used to retrieve relevant literature on PID animal models published from 2013 to 2023 in China Knowledge Network Infrastructure(CNKI),Wanfang,and PubMed databases.The studies were analyzed and categorized based on experimental animal types,modelling methods,modelling cycles,detection indicators,positive control drugs,and administration duration.A database was established for statistical analysis.Results A total of 214 research articles on PID animal models meeting the inclusion criteria were identified.The most commonly used model animals are Sprague Dawley(SD)rats,followed by Wistar rats.The most frequently employed modelling method is a combination of mechanical injury and bacterial infection,followed by the phenol mucilage method.The most common modelling cycles for acute pelvic inflammatory disease(APID)and chronic pelvic inflammatory disease(CPID)/sequelae of pelvic inflammatory disease(SPID)are 8 to 14 days,while for PID models without specific staging,the cycles are 7 days.High-frequency detection methods and indicators include histopathological observation using hematoxylin-eosin staining,enzyme-linked immunosorbent assay(ELISA)for serum-related indicators,morphological changes of tissues observed with the naked eye,and immunohistochemical detection of related protein expression in uterine tissues,and pathological scoring.The most frequently used positive control drugs are Fuke Qianjin Tablets,followed by Jingangteng Capsules.The most common administration duration for APID is 7 days,and for CPID/SPID models,it ranges from 15 to 21 days.Conclusion Currently,SD rats and Wistar rats are commonly used as experimental animals for PID models.The dual modelling method of mechanical injury combined with mixed bacterial infection aligns closely with clinical pathogenesis and can be used to establish a PID model that simulates postoperative uterine cavity infection.Depending on the research objectives,different positive drugs and detection indicators should be selected for comprehensive evaluation.Most existing PID animal model studies are based on western medical diagnosis,with fewer studies focusing on Traditional Chinese Medicine(TCM)syndromes.There is a need to integrate TCM theories of etiology and pathogenesis to construct PID animal models that are more in line with TCM clinical symptoms.

Objective To evaluate the efficacy of bare mental stent (BMS) and covered stent (CS) in the treatment of complete central venous occlusive disease (CVOD) in hemodialysis patients.Methods A total of 66 cases of CVOD who have been treated by endovascular methods successfully in the First Affiliated Hospital of Sun Yat-sen University from Jan 2015 to Jan 2017 were enrolled in this study.According to the type of stent,the patients were divided into two groups,BMS group (n=46)and CS group (n=20).The demographic data,clinical signs and symptoms,and pre-procedure and post-procedure imaging data were followed up and recorded.The primary patency rates were calculated at 1,3,6,9,and 12 months.Results The related symptoms were improved within 2 day post-procedure.The primary patency rates of BMS group in 1,3,6,9 and 12 months were 97.83％,95.65％,69.56％,41.3％,and 34.78％ respectively.The rates of CS group were 100％,100％,95％,65％,and 60％respectively.They did not reached statistical significance for primary patency rates between two groups in 1,3,and 6 months (P ＞ 0.05 respectively).However,from 9 months after procedure,it began to show the significant difference between two groups (P ＜ 0.05).The median patency time of the CS group was (10.30±5.32) months,while BMS group was (8.52±0.49) months.The difference between the two groups was statistically significant (P=0.046).Conclusions Stent implantation for complete occlusion of central venous in hemodialysis patients can get credible effect.The use of CS for CVOD provides superior patency as well as patency time in long period after procedure as compared with BMS.

Objective To investigate the expression of CXC chemokine receptor 4 (CXCR4) in clear cell renal cell carcinoma (ccRCC) and its relationship with the clinical pathological parameters of ccRCC.Methods The expression of CXCR4 was detected by immuno-histochemistry method in 63 cases of ccRCCs,20 cases of para-carcinoma tissues and 20 cases of normal renal tissues.The correlation between expression level of CXCR4 and clinical pathological parameters of ccRCC patients were analyzed,and the clinical significance of its expression in ccRCC was evaluated.Results The positive expression rate of CXCR4(49.2％) in ccRCCs was significantly higher than that in para-carcinoma tissues (15％) and normal renal tissue (10％),and the difference was statistically significant (P ＜ 0.05).The expression level of CXCR4 and the clinical stage and pathological grade of ccRCC were correlated (P ＜ 0.05),and was associated with lymph node transfer (P ＜ 0.05).The CXCR4 negative group overall survival rate [55.2％ (16/29)] and the average survival time(46 months) was significantly better than the positive group [38.5％ (10/26),32 months;P ＜ 0.05].Conclusions The expression level of CXCR4 in ccRCC is correlated with the clinicopathological parameters and prognosis.CXCR4 is expected to be an important marker for diagnosis and prognosis evaluation of renal cell carcinoma.

Objective To explore the safety and feasibility of guiding catheter passing through spasmodic vessels in patients undergoing percutaneous coronary intervention (PCI) via radial artery access by the aid of PCI guiding wire and balloon .Methods The clinical data of 33 coronary artery disease (CAD) patients undergoing PCI via radial artery access with radial artery or (and) brachial artery spasm ( group A ) were retrospectively analyzed .Among all these patients , guiding catheters were delivered through the spasmodic vessels successfully by the aid of PCI guiding wires and balloons .The clinical data of other 38 CAD patients having PCI during the same period performed by other operators via radial artery or ( and ) brachial artery approach and experienced vessel spasm were anlysed as the control ( group B ) .All patients in group B received conventional anti-spasm management during PCI .All vessel spasm was identified by angiography.For patients in group A , a diameter of 0.014 inch guiding wire was chosen to pass through the spasmodic vessel segment carefully and gently .The diameter of balloon should be chosen according to the diameter of guiding catheter .A balloon diameter of 2.0 mm and 2.5 mm was corresponded to 6F and 7F guiding catheter respectively .The balloon was advanced to the tip of guiding catheter , keeping a half in catheter and a half in vessel followed by inflating the balloon with a pressure of 8 atm.The balloon was kept inflated the guiding catheter was pushed in vitro carefully and slowly until the catheter passed through the spasmodic vessel segment .Then the balloon was deflated and pulled out together with PCI guiding wire . Exchanged a diameter of 0.035 inch wire and completed the positioning of guiding catheter .After finishing the PCI, radial or ( and) brachial angiography was performed again to observe if spasm disappeared and to determine if there any contrast medium exudation .For patients in group B , routine approach was applied including administration of nitroglycerine , diltiazem or nitroprusside etc . to relieve vessel spasm. Results The location of vessel spasm was similar in group A and group B ( P=0.150 ) , and the incidence rate of spasm in brachial artery was higher than that in radial artery in both groups .The chance of guiding catheter crossing the spasmodic vessel segment was significantly higher in group A than in group B ( 100%vs.39.5%, P=0.00).In patients whose guiding catheter could pass through the spasmodic vessel segment successfully , time spent in group A was shorter than in group B ( P=0.000 ) .The patient number which time spent was less than five minutes , five to 15 minutes and more than 15 minutes was 30 and 2 ( 90.1%vs.13.3%) , 3 and 7 ( 9.9% vs.46.7%) and 0 and 6 ( 0% vs.40.0%) in group A and in group B respectively.The incidence of forearm hematoma was lower in group A than in group B without statistical difference [6.1%(2/33) vs.18.4%(7/38), P =0.113].Conclusions It is safe and feasible for passing guiding catheter through spasmodic vessels during PCI via radial artery access by the aid of PCI guiding wire and balloon .

OBJECTIVE To investigate the clinical pathological characteristics of differentiated thyroid carcinoma (DTC) in children and adolescents. METHODS The clinical data of 30 children and adolescents with DTC were retrospectively reviewed. Meanwhile the clinical pathological characteristics of DTC were analyzed according to patients' age and gender. RESULTS Papillary thyroid carcinoma (PTC) was found in 27 cases and follicular thyroid carcinoma (FTC) in 3 cases. The average diameter of tumors was (2.56±1.1) cm. In the group of children, the incidence of lymph node metastasis was 92.3% (12/13), pulmonary metastasis was 46.2% (6/13), and those in the group of adolescents was 88.2% (15/17) and 35.3% (6/17) respectively. Children group tended to present with more vascular invasion, thyroid capsule invasion, and invasion out of thyroid, and a higher rate of cervical lymph node metastasis (P=0.025, 0.007, 0.025, 0.033). CONCLUSION Thyroid carcinoma in childhood and adolescent has a stronger invasive feature. It is easy to local invasion, lymph node and distance metastasis.
