By systematically reviewing the development history of organoid technology and its application examples in Chinese med-icine,this paper summarizes the specific applications of organoids in the mechanism and translation of Chinese medicine,pathological mechanisms,diagnostic techniques,and therapeutic strategies,and evaluate their advantages and limitations through literature analysis.Organoid technology provides an in vitro model that highly simulates the function of human organs for TCM research,and can simulate the multi-target and multi-pathway mechanism of action of TCM,which significantly improves the scientificity and precision of TCM in the analysis of disease mechanisms,drug screening and personalized treatment.However,it still faces challenges in stand-ardization,ethical regulation,and clinical translation.The combination of organoid technology and TCM has a broad prospect,and it is necessary to further optimize the model construction,resolve ethical issues,and promote its wide application in TCM research and clin-ical practice through technological innovation,interdisciplinary cooperation,and international regulatory coordination in the future.

Objective:To analyze the effect of altitude on NIH-CPSI score in patients with chronic prostatitis/chronic pelvic pain syndrome(CP/CPPS)Methods:Clinical data and the results of NIH-CPSI Questionnaire of the 321 patients with CP/CPPS at different altitudes were collected from March 2021 to March 2022.And the influence of altitudes on NIH-CPSI score of CP/CPPS was analyzed.Result:The NIH-CPSI score of patients living at an altitude of 4 300 m was significantly higher than that of patients living at an altitude of 1 500 m and 2 200 m.The CP/CPPS patients who lived in the higher altitude had more severe symptoms of pain and urination as well as lower scores of life quality(P＜0.05).Conclusion:NIH-CPSI score increased significantly with higher alti-tude,indicating more severe symptoms and decreased quality of life in CP/CPPS patients.These findings highlight the need for man-agement strategies for specific heights in patients with CP/CPPS.

Oral cancer is one of the most common malignant tumors in the head and neck,with approximately 90%of oral cancer being squamous cell carcinoma.Oral squamous cell carcinoma(OSCC)has a high degree of malignancy and a poor prognosis,posing a serious threat human health.The occurrence and development of OSCC are relatively complex,influenced and regulated by multiple factors and levels,and the molecular mechanisms is currently not fully understood.Long non-coding RNA(lncRNA)can exert various biological functions by regulating gene expression and function at the transcriptional,translational,and post-translational lev-els.The occurrence and development of OSCC involve the abnormal expression of lncRNA.Therefore,this article reviews the relevant research on the function and molecular mechanisms of lncRNA in OSCC,in order to provide a reference for future studies.

Objective To investigate the dosimetric differences in preoperative short-course volumetric modulated arc therapy(VMAT)for rectal cancer using different fluence smoothing(FS)levels in the Monaco Treatment Planning System(Monaco TPS).Methods Twenty rectal cancer patients who received preoperative neoadjuvant short-course VMAT at some hospital from September 2021 to December 2022 were retrospectively selected.Four groups of radiotherapy plans were formulated using the Monaco TPS for each case,which were classified into an off group,a low group,a medium group and a high group based on the FS levels.Then the four groups were compared in terms of the dosimetric parameters,monitor unit and number of the segments in the planning target volume(PTV)and organ at risk(OAR).Statistical analysis was performed using SPSS 27.0 software.Results All the four groups had the doses to the target volume meeting clinical requirements,which had no significant differences in the doses to 5％(D5％)and 95％(D95％)to the target volume and the maximum dose(Dmax),minimum dose(Dmin),mean dose(Dmean)and conformity index(all P＞0.05).Statistical differences were found between the homogeneity indexes of the four groups(P＜0.05),with the medium group behaving the best.The number of the segments rose while the mornitor units decreased siginificantly with the increase of FS levels,with the differences being statistically significant(P＜0.05).There were no significant differences between the V25,V20,V15 and V10 of the small intestine,the V25 and V20 of the bladder and the V15 and V10 of the left and right femur(all P＞0.05).Conclusion In preoperative short-course VMAT for rectal cancer,clinical requirements can be met with different FS levels in the Monaco TPS,and medium-level FS results in optimal overall dose distribution in terms of treatment planning.[Chinese Medical Equipment Journal,2025,46(5):48-53]

Objective:To explore the application efficacy of Buzhong Yiqi Decoction combined with Chinese Herbal Pack Therapy in elderly female patients with internalrectal prolapse of qi deficiency type after surgery.Meth-ods:A total of 71 olderly female patients with internal rectal prolapse of qi deficiency type admitted to the Depart-ment of Anorectal Surgery of our Hospital from February 2023 to October 2024 were selected and randomly divided into a treatment group of 36 cases and a control group of 35 cases.Both groups were treated with modified Gant sur-gery.The treatment group received oral administration of Buzhong Yiqi Decoction combined with Chinese Herbal Pack Therapy after surgery,while the control group received no Traditional Chinese medicine intervention.Results:Post-operative symptoms such as defecation disorders and rectal bearing-down sensation in both groups were significantly improved compared with those before surgery(P<0.05).The treatment group showed significantly better improvement in symptoms such as defecation disorders,rectal bearing-down sensation,and at 6 months after surgery compared with the control group(P<0.05).The scores of the Constipation Severity Index(CSI)in both groups were significantly lower after surgery than before(P<0.05),and the scores of the treatment group at 1 month and 6 months after surgery were significantly lower than those of the control group(P<0.05).The rectal contraction pressure and rectal-anal pres-sure gradient in both groups were higher after surgery than before(P<0.05),and the increase was more significant in the treatment group at 1 month and 6 months after surgery(P<0.05).No serious complications occurred in either group after surgery.Conclusion:Buzhong Yiqi Decoction combined with Chinese Herbal Pack Therapy can improve postop-erative symptoms,defecation disorders,and anorectal function in elderly female patients with internal rectal prolapse of qi deficiency type,and improve the short-term and long-term efficacy of patients after surgery.

Objective:To explore the expression regulation of lipid metabolism gene ABHD5 in testes.Methods:Differential gene analysis was performed by integrating databases of TCGA and GTEx to identify the target gene ABHD5.The expression trends of ABHD5 gene in testicular carcinoma tissue were analyzed.Human testis single-cell atlases were obtained from the Human Protein Atlas and Male Health Atlas databases to determine the expression distribution of ABHD5 across different testicular cell types.Additionally,the GTEx database was utilized to visualize the expression pattern of ABHD5 in the testis,thereby enhancing the understanding of its transcriptional profile.The relationship between ABHD5 expression and age was assessed through integrated database analysis.Western blotting and immunofluorescence were performed to detect differential expressions of ABHD5 in testicular tissues of young and aged mice respectively.Results:The TCGA database indicated that the expression of ABHD5 in human testicular carcinoma tissue was significantly lower than that in normal testicular tissue which showed a negative correlation with patient survival.ABHD5 was highly ex-pressed in germ cells of the testis reveaked from Human Protein Atlas and Male Health Atlas databases.The stability of ABHD5 protein was crucial for testicular tissue,and its expression decreased with age.Furthermore,Western blot and immunofluorescence staining demonstrated that ABHD5 expression in the testicular tissue of aged mice was significantly lower than that in young mice.Conclu-sion:ABHD5 plays an important role in testicular tissue,and may be inseparable from testicular tumors and reproductive aging.How-ever,its mechanism of action remains to be further studied.

This paper investigated the inhibitory effect of carbonized Scutellariae Radix(Cb-SR) on pyroptosis in endometrial epithelial cells of mice with endometritis and its correlation with the IKBKE/NLRP3 signaling axis. Mice model of endometritis was established by using an intrauterine injection of 10 μL polysaccharides(LPS, 5 mg·mL~(-1)), and the mice were randomly divided into model group(LPS), low-dose group of Cb-SR(L-Cb-SR, 0.55 g·kg~(-1)), medium-dose group of Cb-SR(M-Cb-SR, 1.10 g·kg~(-1)), high-dose group of Cb-SR(H-Cb-SR, 2.20 g·kg~(-1)), crude Scutellariae Radix group(Cr-SR, 1.63 g·kg~(-1)), and Fuke Qianjin Capsule group(FQC, 0.30 g·kg~(-1)), with 10 mice in each group. Ten healthy female mice were selected and injected with PBS of equal volume into the bilateral uterus, and they were set as the sham group. The mice in the drug treatment groups were given the corresponding doses of Cb-SR, Cr-SR, FQC, or physiological saline of equal volume by gavage twice a day for seven days. Thirty minutes after the last administration, each mouse was euthanized by cervical dislocation. Hematoxylin-eosin(HE) staining and transmission electron microscopy were applied to observe the histopathological morphology of the uterine tissue. Immunohistochemistry was used to detect the expression of CD38 and CD138. Myeloperoxidase(MPO) values in neutrophils were measured by the kit; Enzyme-linked immunosorbent assay(ELISA) was used to measure the secretion of interleukin-18(IL-18), interleukin-1β(IL-1β), and tumor necrosis factor-α(TNF-α). Immunofluorescence and Western blot were used to analyze the expression of the proteins related to the IKBKE/NLRP3 signaling axis. Mouse endometrial epithelial cells(MEECs) were separated and purified from the uterine tissue of pregnant female mice through in vitro experiments and injured by LPS for 24 h, and then they were cultured with Cb-SR-containing serum. The anti-endometritis effect of Cb-SR was investigated by CCK-8 assay, scanning electron microscopy, and Western blot. The results showed that Cb-SR significantly reduced MPO values, attenuated uterine tissue damage, inhibited the expression of CD38 and CD138, decreased the levels of IL-1β, IL-18, and TNF-α, and inhibited the expression of proteins associated with IKBKE/NLRP3 signaling axis in mice with endometritis. In addition, Cb-SR-containing serum reduced swelling of MEECs organelles induced by LPS, decreased the expression of inflammatory factors, and suppressed the expression of IKBKE/NLRP3 signaling axis-related proteins. These results suggest that Cb-SR can inhibit endometrial epithelial cell pyroptosis in endometritis by suppressing the IKBKE/NLRP3 signaling axis.
