AIM:To elucidate the intervention and mechanism of 4'-hydroxychalcone(4-HC)in colitis mice through the regulation of Th17/Treg homeostasis.METHODS:Using a dextran sodium sulfate(DSS)-induced colitis model in mice,we meticulously observed the pathological characteristics of colon tissue via HE staining.Additionally,we employed immunohistochemical analysis and Western blot techniques to assess the expression levels of proteins associated with the JAK/STAT signaling pathway,as well as the specific content of tight junction proteins such as ZO-1 and occludin.The differentiation of Th17 and Treg cells was analyzed through flow cytometry.RESULTS:Compared to the normal group,the DSS group exhibited a consistent decline in body weight,coupled with symptoms of diarrhea and hematochezia,an increase in the DAI score,and a notable reduction in colon length.In contrast,the body weight of the 4-HC group dis-played an upward trend following an initial decrease,with improvements in diarrhea and hematochezia symptoms,a reduc-tion in the DAI score,and a restoration of colon length relative to the model group.The integrity of colon tissue in the 4-HC group was significantly better than that in the DSS group,evidenced by a marked increase in the number of goblet cells and an enhancement in crypt integrity,while the average histology score showed a decrease.Western blot analysis re-vealed substantial increase in ZO-1 and occludin expression after 4-HC treatment.Flow cytometry results indicated a dra-matic decrease in the differentiation rate of Th17 cells in spleen lymphocytes and mesenteric lymph nodes,while the dif-ferentiation rate of Treg cells was significantly elevated.Immunohistochemical and Western blot analyses demonstrated that 4-HC markedly reduced the phosphorylation of STAT1 and STAT3,while up-regulating the phosphorylation of STAT6,suggesting that 4-HC modulates CD4+T cell activity through the JAK-STAT pathway.CONCLUSION:The 4-HC may enhance the course of DSS-induced colitis in mice,alleviate colonic tissue damage,and modulate the balance be-tween Th17 and Treg cells,potentially involving the JAK/STAT signaling pathway.

4.Artificial disc replacement for the treatment of cervical disc herniation.
China Journal of Orthopaedics and Traumatology 2024;37(11):1051-1055
OBJECTIVE:
To investigate the clinical efficacy of artificial cervical disc replacement for cervical disc herniation.
METHODS:
Retrospective analysis of 24 patients with cervical disc herniation with 24 segments admitted from July 2016 to July 2022, including 12 males and 12 females, with an average age of (50±2) years old ranging from 36 to 68 years old. The intervertebral space height of the lesion segment before replacement was 4.3 to 7.2 mm with an average of (5.6±1.6) mm, the range of motion of anterior flexion and posterior extension was 5.6° to 7.2° with an average of (6.4±1.3)°, the range of motion for the left and right lateral flexion was 10.2° to 11.4° with an average of (10.7±1.8)°, and the Japanese Orthopaedic Association (JOA) score was 8 to 13 scores with an average of (8.0±0.3) scores. Through anterior incision, artificial cervical disc replacement surgery was performed after cervical discectomy and decompression.
RESULTS:
After surgery, all patients'incisions healed well. All patients were followed up from 12 to 60 months with an average of (33±12) months. At the final follow-up, the intervertebral space height of replacement segment was 4.0 to 6.8 mm with an average of (5.4±1.3) mm, the range of motion of anterior flexion and posterior extension was 4.6° to 6.4°with an average of (5.6±1.2)°, the range of motion of left and right lateral flexion was 8.7°to 10.3°with an average of (9.5±1.5)°. The prosthesis did not shift or sink, slight heterotopic ossification occurred within the operative segment(ⅠorⅡgrade). The height of adjacent intervertebral spaces was not lost, there was no vertebral degeneration, no significant change in the comparison of adjacent segment mobility before and after surgery. The JOA score increased from (8.0±0.3) scores before replacement operation to (15.0±0.2) scores after operation.
CONCLUSION
Artificial cervical disc replacement surgery can not only obtain the same efficacy as the anterior cervical disc fusion surgery, but also avoid the increase of compensatory stress of adjacent segments, maintain the stability of the biomechanical environment, thereby reducing the incidence of degeneration of adjacent segments, and can be used as an effective method for the treatment of cervical disc herniation, , but the long-term efficacy and the existing problems of replacement surgery need to be further studied and solved in the future.

Objective:To explore the effects and mechanism of zedoary turmeric oil and its active components on the vascular endothelial growth factor A (VEGFA), signal transducer and activator of transcription 3 (STAT3), and mechanistic target of rapamycin (mTOR) in the ovarian cancer (OC). Method:Network pharmacology technology was employed to analyze the mechanism of Curcumae Rhizoma on OC. Bioinformatics was used to analyze the expression of VEGFA, STAT3, and mTOR in OC and the effect on the prognosis of OC to explore the feasibility of zedoary turmeric oil in regulating VEGFA, STAT3, and mTOR in OC.The xenograft tumor model of nude mice was established, and the effects of zedoary turmeric oil and its active components on VEGFA, STAT3, and mTOR in OC were observed by hematoxylin-eosin (HE) staining, real-time fluorescence-based quantitative polymerase chain reaction (Real-time PCR), Western blot, and immunohistochemistry (IHC). Result:Bioinformatics analysis and literature research showed that VEGFA, STAT3, and mTOR played a special regulatory role in the occurrence and development of OC, and were potential key targets for the proliferation of OC. Network pharmacology analysis revealed that Curcumae Rhizoma could regulate multiple disease targets of OC, and mediate VEGFA, STAT3, and mTOR in OC through these multiple targets. As demonstrated by HE staining, the tumor cells in the model group were densely arranged, with no erosion on the edge and no vesicles inside. Compared with the model group, the cell density in other treatment groups was reduced, and strip-shaped erosion on the edge and small empty vesicles were observed in the tumor tissue, especially in the zedoary turmeric oil group. According to the results of Real-time PCR and IHC, zedoary turmeric oil and its active components could inhibit the mRNA and protein expression of VEGFA, STAT3, and mTOR in the OC tissue (

The development of Chinese medicine and Western medicine andrology is based on different social background and academic systems, either Chinese medicine or Western medicine andrology has their limitations, therefore, integration of Chinese and Western medicine (ICWM) andrology is in a great need. After more than 30 years of development, andrology has made great achievements in the construction of specialized academic association, holding academic conferences and publication of academic monographs, and the research progress on this field is mainly in the combination of disease and syndrome, microdifferentiation of symptoms and signs and basic research development. However, the comprehensive theoretic system of ICWM andrology has not yet established, and the related studies are still on the primary stage. In the future studies, great efforts still need to be made to expand the methods for the investigation of ICWM, and make innovations in the field of andrology.
