Objective To observe the clinical efficacy of acupuncture at Front Mu point in the treatment of ulcerative colitis.Methods Sixty patients with ulcerative colitis treated at the Traditional Chinese Medicine Hospital in Kunming from August 2022 to June 2023 were collected.Using a random number table method,30 cases were assigned to each of the control group and the combined group.The treatment method involved administering oral mesalazine to the control group for a continuous period of 8 weeks,while the combined group received both oral mesalazine and acupuncture at front Mu points.The clinical efficacy,colonoscopy results score(Baron score),and colonic mucosal healing score(Geboes)before and after treatment were compared.Follow-up was conducted at 3 months to calculate the recurrence rate in the combination and control groups.Results The total effective rate in the combination group was higher than that in the control group(P<0.05),with rates of 93.33%and 67.67%,respectively.After treatment,the disease activity index,Baron score,and Geboes score decreased compared to before treatment(P<0.05),and the combination group had a lower disease activity index,Baron score,and Geboes score than the control group after treatment(P<0.05).Comparing the recurrence rates at 3 months post-treatment,the combination group was lower than the control group.Conclusion Acupuncture at Front Mu Point can significantly improve the clinical symptoms of ulcerative colitis,reduce the recurrence rate compared to patients in the control group,and is safe and reliable without serious adverse reactions.

Objective To explore the application value of Three-Dimensional rectal cavity ultrasound combined with contrast agent imaging in necrotizing fasciitis of the anal region.Methods Before surgery,standard three-dimensional rectal cavity ultrasound examinations(referred to as the conventional group)and contrast agent imaging examinations(referred to as the imaging group)were conducted for 40 patients clinically diagnosed with anal region necrotizing fasciitis.Separate observations were made for the primary lesion,as well as for the depth and superficial necrosis of the fascia,and injuries to the anal sphincter muscle.Comparative analysis with surgical results was undertaken to assess the diagnostic sensitivity of both the conventional and imaging groups.Results In comparing the conventional group with the imaging group,the rates of primary lesion visibility rose significantly from 70%to 97.5%,deep fascial necrosis visibility increased from 50%to 88.8%,superficial fascia visibility improved from 70%to 100%,and the visibility of anal sphincter muscle injury escalated from 62.5%to 97.2%,all demonstrating statistical significance at P<0.05.Conclusions Three-dimensional rectal cavity ultrasound combined with contrast agent imaging exhibits significantly enhanced accuracy in identifying primary lesions associated with perianal necrotizing fasciitis,as well as the necrosis affecting deep and superficial fascia,in contrast to conventional three-dimensional rectal cavity ultrasound.This advancement offers more precise guidance for clinicians in devising surgical plans,thereby augmenting the success rate of surgical interventions.

Emphasizing symptom efficacy is an important manifestation of the personalized diagnosis and treatment of traditional Chinese medicine （TCM）. However， in current clinical practice of TCM， there are challenges such as diverse symptom expressions， difficulty in standardization， inconsistent evaluation standards for symptom efficacy， lack of universal quantitative methods， and complexity in collecting complete and accurate symptom information. These issues hinder the full and effective utilization of symptom information. Addressing the current research status and existing problems of symptom terminology standardization， quantification and grading of symptom efficacy， and collection of symptom information， this paper proposes methodological strategies for effectively recording and utilizing TCM symptom efficacy information in the era of big data. These strategies include collecting TCM symptom information based on patient reporting， standardizing the evaluation of TCM symptom efficacy from measurement scales and evaluation dimensions， integrating TCM symptom efficacy evaluation into clinical diagnosis and treatment processes， and utilizing artificial intelligence technology to acquire and process TCM symptom efficacy information. TCM symptom efficacy evaluation strategies based on patient perspectives and artificial intelligence technology will help fully explore the value of data elements， promote the objective demonstration of the specific efficacy of TCM， and facilitate the discovery of effective patterns.

Objective : To investigate the effect of miR-141-3p on LPS induced A549 cell injury by targeting high mobility group protein 1 (HMGB1) ． Methods : A549 cells derived from type Ⅱ alveolar epithelial cells were taken as the study object，miR-141-3p mimics，mimics NC，HMGB1 gene overexpression plasmid (pcDNA3. 1-HMGB1) and empty Vector were transfected into A549 cells respectively or co-transfected，then 10 μg / ml LPS was used for 24 h．Cell proliferation activity was detected by cell counting kit-8 ( CCK-8) ．The activity of lactate dehydrogenase ( LDH) in the supernatant of cell culture was detected by colorimetry．The apoptosis level of each group was detec- ted by flow cytometry．The levels of interleukin (IL) -1 β , IL-6 and tumor necrosis factor α (TNF-α) were detected by enzyme-linked immunosorbent assay (Elisa) ．Dual luciferase reporter gene assay verified the targeted regulatory relationship between miR-141-3p and HMGB1 . Results : After treatment with LPS ，the proliferative activity of A549 cells and the expression level of miR-141-3p decreased ( P ＜0. 05 ) ，the apoptosis rate increased ( P < 0. 05) ，the levels of IL-1 β , IL-6，TNF-α and the activity of LDH in supernatant increased (P＜0. 05) ．Overex- pression of miR-141-3p increased the proliferation activity of A549 cells treated with LPS (P ＜0. 05 ) ，and de- creased the apoptosis rate and the levels of IL-1 β , IL-6，TNF-α in cells and LDH activity in supernatant (P < 0. 05) ．However，overexpression of HMGB1 gene could reverse the ameliorative effect of miR-141-3p on LPS-in- duced A549 cell injury．Dual luciferase reporter gene experiment confirmed that HMGB1 was the downstream target gene of miR-141-3p． Conclusion miR-141-3p can inhibit LPS-induced apoptosis，reduce the expression level of inflammatory factors，and improve the damage of A549 cells，which may be related to the targeted regulation of HMGB1 expression.
