This paper interprets the disease name related to bi （痹） disease in traditional Chinese medicine （TCM） from the perspective of micropathological phenotypes in knee osteoarthritis （KOA）. By systematically reviewing classical TCM literature on the pathogenesis and clinical features of different subtypes such as damp-retention bi， bone bi， and tendon bi， and integrating these with current research on pathological subtypes of KOA including the synovitis type， cartilage-meniscus type， and subchondral bone type， the study explores the correlation between traditional disease terms and modern micropathological phenotypes. The author proposes subtype classifications of damp-retention bi corresponding to synovial inflammation， bone bi related to abnormal subchondral bone remodeling， and tendon bi representing cartilage and meniscus degeneration. This approach provides a microscopic biological explanation for TCM syndrome differentiation and offers new perspectives for advancing integrative diagnostic and therapeutic strategies in both Chinese and western medicine.

Artificial intelligence （AI） and population pharmacokinetics （PPK） technologies have demonstrated significant potential in the personalized medication of immunosuppressants after organ transplantation, enabling precise prediction of drug dosages. This article provides a comprehensive review of the application status of AI and PPK in the individualized administration of immunosuppressants after organ transplantation， focuses on monitoring blood drug concentration， predicting efficacy/adverse reactions， and establishing individualized dosing models for organ transplant recipients after immunosuppressant administration， and analyzes and compares the application characteristics of different methods in different organ transplant patients as well as the integration and future development of AI and PPK technologies. AI and PPK technologies can not only significantly reduce the dependence on human resources， but also greatly improve the level of individualized treatment of immunosuppressants after organ transplantation， and reduce the discomfort and burden caused by frequent blood concentration monitoring to patients.

Glucagon-like peptide-1 （GLP-1） receptor agonists are a novel class of antidiabetic drugs that also possess lipid- lowering and cardiovascular protective effects， with liraglutide and semaglutide being their representative medications. Based on a systematic literature search， this review summarizes the lipid-lowering mechanisms by which liraglutide and semaglutide exert direct effects on the liver and kidney （regulating autophagy， key lipid metabolism pathways， reverse cholesterol transport， etc.）， direct actions on adipose tissue （affecting adipocyte proliferation and differentiation， expression of lipid metabolism proteins， and gene transcription）， activation of sympathetic pathways through the central nervous system， and modulation of the gut microbiota. Additionally， it summarizes the clinical evidence of their lipid-lowering effects in populations with type 2 diabetes mellitus， overweight individuals， and others. These findings indicate that GLP-1 receptor agonists exert lipid-lowering effects by acting on multiple tissues or systems， providing crucial evidence for further elucidating the molecular mechanisms of these drugs in lipid regulation and exploring potential new ideas for their clinical applications.

AIM: To investigate the application of biological amniotic membrane soaked in pirfenidone(PFD)and to evaluate its anti-scarring effect and toxic side effects on glaucoma model of rabbit eyes.METHODS: The right eyes of 72 healthy New Zealand white rabbits were randomly divided into 0.5%PFD+ biological amniotic membrane group, biological amniotic membrane group, mitomycin C(MMC)group and blank control group after the glaucoma model was established by anterior chamber injection of compound carbomer solution, and 18 rabbits in each group underwent trabeculectomy, in which the 0.5% PFD+ biological amniotic membrane group was placed with 0.5% PFD solution-soaked biological amniotic membrane under the scleral flap, and the biological amniotic membrane group was placed with normal saline-soaked rehydrated biological amniotic membrane under the scleral flap. In the MMC group, a cotton pad soaked in MMC was placed under the scleral flap for 3 min and immediately rinsed with normal saline, while the blank control group received no implant after the scleral flap was made. The intraocular pressure(IOP), filtration blebs, toxic side effects and complications were evaluated, and the histopathological changes in the filtration area were observed by hematoxylin-eosin(HE), Masson staining and immunohistochemical staining.RESULTS: The mean IOP at 14, 21 and 28 d after trabeculectomy were 0.5%PFD+ biological amniotic membrane group<MMC group<biological amniotic membrane group<blank control group(all P<0.05). At 28 d after trabeculectomy, 0.5%PFD+ biological amniotic membrane group had the best effect of anti-inflammatory hyperplasia and inhibition of collagen formation, the highest survival rate of filtration blebs, and the inflammatory reaction was mild.CONCLUSION: Biological amniotic membrane soaked in pirfenidone has more obvious anti-scarring effect on glaucoma model, with less toxic side effects and good safety.

BACKGROUND:Acupotomy is effective in the treatment of knee osteoarthritis,but its mechanism is not very clear. OBJECTIVE:To observe the effect of acupotomy on the apoptosis of knee chondrocytes in knee osteoarthritis rats based on osteoclast associated receptor(OSCAR)-tumor necrosis factor-associated apoptosis-inducing ligand(TRAIL)-osteoprotetin(OPG)pathway. METHODS:Twenty-seven Sprague-Dawley rats were randomly divided into normal group(n=9),model group(n=9)and acupotomy group(n=9).Rats in the normal group were routinely housed without any treatment.Animal models of knee osteoarthritis were established by knee injection of papain.Acupotomy intervention was performed 1 week after modeling,once a week for a total of three times.Relevant tests were performed at the end of the intervention. RESULTS AND CONCLUSION:The Lequesne MG behavioral scores of rats in the model group were elevated compared with the normal group(P<0.01),while the Lequesne MG behavioral scores of rats in the acupotomy group were decreased comparedwith the model group(P<0.01).Hematoxylin-eosin staining results showed that compared with the normal group,the cartilage surface of the rat's knee joints in the model group was worn and uneven and the chondrocytes were swollen,ruptured,reduced in number,and arranged disorderly;while the cartilage surface of the rat's knee joints in the acupotomy group was relatively smooth,and the chondrocytes were high in number and arranged in an orderly manner,with the structure basically clear.Immunohistochemical staining results showed that compared with the normal group,the positive expressions of OSCAR and TRAIL were increased in the model group(P<0.01),while the positive expression of OPG was decreased(P<0.01).Compared with the model group,the positive expressions of OSCAR and TRAIL in the acupotomy group were decreased(P<0.01),while the positive expression of OPG was increased(P<0.01).TUNEL staining results showed that compared with the normal group,the number of apoptotic cells in the model group were increased(P<0.01);compared with the model group,the number of apoptotic cells in the acupotomy group decreased(P<0.01).RT-qRCR and western blot results showed that compared with the normal group,the protein expressions of OSCAR,TRAIL and Bax in the model group were increased(P<0.01),and the protein expressions of OPG and Bcl-2 were decreased(P<0.01);compared with the model group,the protein expressions of OSCAR,TRAIL,and Bax in the acupotomy group were decreased(P<0.01),and the protein expressions of OPG and Bcl-2 were increased(P<0.01).To conclude,acupotomy can reduce cartilage injury of the knee joint in rats with knee osteoarthritis,which may be related to the blockage of mitochondrial pathway apoptotic signaling release by the OSCAR-TRAIL-OPG pathway.

Osteoporosis and knee osteoarthritis often co-occur and are closely related in terms of epidemiology， clinical symptoms， pathogenesis and other aspects. Therefore， it is necessary to manage the co-morbidity and treat the two as a whole. Based on the overall relationship between wei （痿） and bi （痹） in TCM， it is believed that osteoporosis and knee osteoarthritis have marrow loss and bone atrophy as the core pathogenesis of co-morbidity， and microfractures as the central pathological link. The overall treatment is rooted in boosting kidney， supplementing marrow and strengthening the bones. According to the pathological manifestations of microfractures in the process of co-morbidity， and the different deficiency and excess characteristics of wei and bi， it can be divided into three types， "wei emerging with mild bi"， "wei and bi progressing simultaneously"， and "emphasis on both wei and bi"， for treatment. In terms of "wei emerging with mild bi"， that is the early stage of osteoporosis， the traditional Daoyin （导引） is the main therapy. For "wei and bi progressing simultaneously"， it can be divided into three stages further， including the onset stage， remission stage， and recovery stage of knee pain， treated with Taohong Siwu Decoction （桃红四物汤）， Bushen Huoxue Formula （补肾活血方） and self-made Bushen Qianggu Formula （补肾强骨方） as the main formula respectively. For "emphasis on both wei and bi"， the proven formula， Qianggu Zhitong Formula （强骨止痛方）， is taken as the main prescription.

ObjectiveTo evaluate the clinical efficacy of Chaigui Zengmian prescription （composed of Bupleuri Radix， Codonopsis Radix， Scutellariae Radix， Cinnamomi Ramulus， Paeoniae Radix Alba， Astragali Radix， Atractylodis Macrocephalae Rhizoma， and Scorpio） in treating recurrent respiratory tract infections in children with syndrome of Qi deficiency in lung and spleen and the influences of this prescription on immune factors. MethodSixty-six children suffering from recurrent respiratory tract infections due to Qi deficiency in lung and spleen were selected and randomized into a control group （33 cases） and an observation group （33 cases）. The control group received spleen aminopeptide oral lyophilized powder and the observation group was treated with self-made Chaigui Zengmian prescription granules. Both groups were treated for two months （as two consecutive courses of treatment）. The traditional Chinese medicine （TCM） symptom scores and the serum levels of total immunoglobulins （IgA， IgM， and IgG） and T-helper cells （Th1， Th2， and Th1/Th2） were measured in both groups before and after treatment and then compared. Result① After treatment， the TCM symptom scores of both groups declined and the observation group had lower scores than the control group （P<0.05）. ② The observation group［87.50%（28/32）］ had higher total response rate than the control group［96.88%（31/32）］（Z=7.921，P<0.05）.Also the observation group［28.13%（9/32）］ had more cured children than the control group［6.25（2/32）］ （χ²=5.379，P<0.05） ③ After treatment， the serum levels of IgA， IgM， IgG， Th1， and Th1/Th2 elevated while that of Th2 declined （P<0.05）， and the changes were more obvious in the observation group than in the control group （P<0.05）. ConclusionChaigui Zengmian prescription is effective in treating recurrent respiratory tract infections in children with the syndrome of Qi deficiency in lung and spleen. It can alleviate the symptoms and rectify immune disequilibrium， demonstrating a clinical application value.
