Purpose To investigate the clinicopathological features of traditional serrated adenoma(TSA).Methods A retrospective analysis was conducted on the clinical data,endoscopic,and pathological features of 200 TSA patients.HE staining and immunohistochemical staining were performed.The clinical pathological features were statistically analyzed using x2 test,and relevant literature was reviewed.Results There were 114 males(57.0％)and 86 females(43.0％),with ages ranging from 27 to 92 years(mean age 56.2 years).Among the patients,147(73.5％)were aged ≥ 50 years,and 53(26.5％)were aged＜50 years.Of the 207 TSA lesions,143(69.1％)were located in the distal colon and rectum,while 57(27.5％)were in the proximal colon and rectum.Endoscopic features included 72 lesions(34.8％)with a perpendiculated appearance,48 lesions(23.2％)with a flat appear-ance,and some exhibiting a pinecone-like appearance.The maximum diameter of the lesions was ≤ 10 mm in 136 ca-ses(65.7％),and＞10 mm in 71 cases(34.3％).The typical histopathological features of TSA included serrated contours,eosinophilic cytoplasm,pencil-like nuclei,and ectopic crypt foci.The most common pathological type was the classic TSA(152 lesions,73.4％),followed by the mucin-rich TSA(39 lesions,18.8％).12 cases(5.8％)of TSA exhibited high-grade intraepithelial neoplasia(HGIN)and 3 case(1.5％)of TSA progressed to carcinoma,con-sistent with TSA-originated colorectal cancer(TSA-CRC).Immunophenotype:in 34 cases TSA,Ki67 showed diffuse positivity in basal cells and scattered positivity on the surface.In all 35 cases TSA,p53 showed weak positive nuclear positivity(1％to 60％),and PTEN and MLH1 were retained.In the 12 cases of TSA with HGIN and 3 cases of TSA-CRC,Ki67 showed diffusely positive,CK20 was strongly positive diffusely,and MLH1 was retained.In 9 cases of TSA with HGIN,p53 was diffusely strongly positive,and in 12 cases,PTEN was lost.All 3 cases of TSA-CRC showed dif-fuse strong nuclear p53 positivity.The molecular detection showed there were BRAF V600E gene mutation in 8 cases.There were 6 cases with KRAS G12V mutation as well as 1 case with KRAS G13D mutation among the 7 cases of KRAS mutation.The primary surgical approach(111 cases,53.6％)was endoscopic mucosal resection(EMR).Conclu-sion TSA exhibits characteristic histological and endoscopic features.Lesions with a maximum diameter＞10 mum are more likely to progress to HGIN or adenocarcinoma.It is crucial to enhance the awareness of pathologists and clini-cians,particularly regarding TSA with atypical hyperplasia or invasive carcinoma,to avoid misdiagnosis and missed di-agnoses.

Objective:To investigate the clinical application effect of Zishen Yutai Pill in patients with repeated implantation failure (RIF) undergoing frozen-thawed embryo transfer (FET) cycles.Methods:A retrospective case-control study was conducted, selecting 744 cycles of patients with RIF at the Department of Female Reproductive Medicine,State Key Laboratory of Reproductive Medicine and Offspring Health, Center for Reproductive Medicine, Institute of Women, Children and Reproductive Health, Shandong University from October 2017 to April 2023. The patients were divided into experimental group (treated with Zishen Yutai Pill, n=279) and control group (treated without Zishen Yutai Pill, n=465) based on whether Zishen Yutai Pill was added to luteal support. The pregnancy outcomes between the two groups were compared. Based on the different endometrial preparation protocols in the FET cycles, the patients were used down-regulation protocol ( n=271) or non-down-regulation protocol ( n=473). The pregnancy outcomes of the two groups in each protocol were compared. Results:There were no statistically significant differences between the two groups in terms of biochemical pregnancy rate, clinical pregnancy rate, embryo implantation rate, early miscarriage rate, late miscarriage rate, and live birth rate (all P>0.05). However, the biochemical pregnancy rate [69.0% (58/84)], clinical pregnancy rate [59.5% (50/84)], and embryo implantation rate [59.4% (57/96)] in the experimental group of the down-regulated protocol were significantly higher than those in control group [56.1% (105/187), P=0.045; 46.5% (87/187), P=0.048; 44.9% (92/205), P=0.019], with statistically significant differences. In the non-down-regulated protocol, there were no statistically significant differences in pregnancy outcomes between the two groups (all P>0.05). Conclusion:In the FET down-regulated protocol, Zishen Yutai Pill can significantly improve the clinical pregnancy rate and the embryo implantation rate in patients with RIF, thereby improving pregnancy outcomes.

Morita therapy has been bom for more than 100 years.Inpatient Morita therapy is highly oper-able and easy to master.It can improve many refractory neuroses through four-stage treatment.But more neuroses are treated in outpatient clinics,and Morita therapy cannot be used in hospitalized patients.Therefore,the formula-tion of expert opinions on outpatient operations is particularly important.This paper is based on domestic and for-eign references,and after many discussions by domestic Morita therapy experts,and then drew up the first version of the expert opinions on operation of outpatient Morita therapy.Meanwhile the operation rule of Morita therapy in three stages of outpatient treatment was formulated:in the etiological analysis stage,under the theoretical guidance of Morita therapy,analyze the pathogenic factors,to improve treatment compliance and reduce resistance;during the operating stage,guide patients to engage in constructive and meaningful actions,realizing the achievement of letting nature take its course principle;in the cultivating character and enriching life stage,pay attention to positive infor-mation,expanding the scope and content of actions,improving the ability to adapt to complex life,and preventing recurrence caused by insufficient abilities.It will lay a foundation for the promotion of Morita therapy in domestic outpatient clinics,so that more patients with neurosis and other psychological diseases could receive characteristic Morita therapy treatment in outpatient clinics.

Interleukin (IL)-17A, a pro-inflammatory cytokine, is a fundamental function in the onset and advancement of multiple immune diseases. To uncover the primary compounds with IL-17A inhibitory activity, a large-scale screening of the library of traditional Chinese medicine constituents and microbial secondary metabolites was conducted using splenic cells from IL-17A-GFP reporter mice cultured under Th17-priming conditions. Our results indicated that some aureane-type sesquiterpene tetraketides isolated from a wetland mud-derived fungus, Myrothecium gramineum, showed remarkable IL-17A inhibitory activity. Nine new aureane-type sesquiterpene tetraketides, myrogramins A-I ( 1, 4- 11), and two known ones ( 2 and 3) were isolated and identified from the strain. Compounds 1, 3, 4, 10, and 11 exhibited significant IL-17A inhibitory activity. Among them, compound 3, with a high fermentation yield dose-dependently inhibited the generation of IL-17A and suppressed glycolysis in splenic cells under Th17-priming conditions. Strikingly, compound 3 suppressed immunopathology in both IL-17A-mediated animal models of experimental autoimmune encephalomyelitis and pulmonary hypertension. Our results revealed that aureane-type sesquiterpene tetraketides are a novel class of immunomodulators with IL-17A inhibitory activity, and hold great promise applications in treating IL-17A-mediated immune diseases.

Objective:To compare the clinical efficacy of hyperbaric oxygen combined with herbal cake-separated moxibustion on umbilicus and retention enema in treating acute radiation proctitis（ARP），and to statistically analyze their rates of acceptance and satisfaction.Methods:A total of 64 patients with ARP after radiotherapy for cervical cancer treated in Linyi Central Hospital from June 2016 to December 2021 were selected and divided into observation group（ n=32）and control group（ n=32）according to the number table method. The control group was treated with（Smecta and Kangfuxin solution）retention enema combined with hyperbaric oxygen，and the observation group was treated with herbal cake-separated moxibustion on umbilicus combined with hyperbaric oxygen. The degree of rectal injury before and after radiotherapy was evaluated according to the criteria of the Radiation Therapy Oncology Group（RTOG），and the clinical efficacy was analyzed. The symptom score and total score of ARP patients were calculated by international scoring standards for long-term complication of radiotherapy，and the satisfaction rate and acceptance rate of the two groups were analyzed. Results:After four courses of treatment，compared with the same group before treatment，the classifications of clinical symptoms in both the observation group and the control group were significantly improved（ P < 0.01），but there was no significant difference between the observation group and the control group（ P > 0.05）. The acceptance rate and satisfaction rate of patients treated with herbal cake-separated moxibustion on umbilicus in the observation group was significantly higher than that in the control group（ P < 0.01）. Conclusion:Both hyperbaric oxygen combined with herbal cake-separated moxibustion on umbilicus and retention enema in treating ARP can achieve good clinical therapeutic effect. As a non-invasive approach，the herbal cake-separated moxibustion on umbilicus can avoid aggravating rectal mucosa and perianal injury caused by repeated drug enema.
