ObjectiveTo investigate the association of the traditional Chinese medicine (TCM) syndrome types of primary liver cancer (PLC) with clinical features and multimodal quantitative radiological features on computed tomography (CT) and magnetic resonance imaging (MRI), and to provide a reference for the objectification of TCM syndrome differentiation and precise diagnosis and treatment. MethodsA retrospective analysis was performed for the clinical data of 312 patients who were diagnosed with PLC in The First Affiliated Hospital of Hunan University of Chinese Medicine from March 2020 to June 2025, and according to the TCM syndrome type, they were divided into stagnation of liver Qi group with 40 patients, stagnation of liver Qi and spleen deficiency group with 109 patients, Qi stagnation and blood stasis group with 62 patients, dampness-heat toxin amassment group with 81 patients, and liver-kidney Yin deficiency group with 20 patients. Clinical features and multimodal quantitative radiological features were compared between the patients with different TCM syndrome types. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups, and the least significant difference t-test was used for further comparison between two groups; the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups, and the Dunn’s multiple test was used for further comparison between two groups; the chi-square test was used for comparison of categorical data between groups, and the Bonferroni method was used for further comparison between two groups. ResultsThere were significant differences between the patients with different TCM syndrome types in China liver cancer staging (CNLC), Child-Pugh class, alanine aminotransferase, aspartate aminotransferase, albumin, direct bilirubin, total bilirubin, prothrombin time, neutrophil, and albumin-bilirubin score (all P<0.05). In the stagnation of liver Qi group, the patients with Child-Pugh class A accounted for 75.00%; among the patients with CNLC stage I PLC, the patients with stagnation of liver Qi accounted for 60.00%, and those with Qi stagnation and blood stasis syndrome accounted for 59.68%, while among the patients with CNLC stage IV PLC, the distribution proportion of dampness-heat toxin amassment (27.16%) and liver-kidney Yin deficiency (30.00%) was significantly higher than that of stagnation of liver Qi (2.50%) (all P<0.05). Radiological examination showed that there were significant differences between the patients with different TCM syndrome types in the number of tumors, ascites, venous tumor thrombus, maximum tumor diameter, intrahepatic metastasis, and lymph node metastasis in the hepatic hilar and retroperitoneal regions (all P<0.05). Compared with the patients with stagnation of liver Qi, the patients with liver depression and spleen deficiency or liver-kidney Yin deficiency were more likely to develop intrahepatic metastasis; the patients with liver depression and spleen deficiency, dampness-heat toxin amassment, or liver-kidney Yin deficiency were more likely to develop lymph node metastasis in the hepatic hilar and retroperitoneal regions; the patients with liver-kidney Yin deficiency were more likely to experience multiple tumors; the patients with liver depression and spleen deficiency or dampness-heat toxin amassment were more likely to develop ascites (all P<0.05). Compared with the patients with Qi stagnation and blood stasis syndrome, the patients with liver depression and spleen deficiency had a significantly longer maximum tumor diameter and a significantly higher proportion of patients with venous tumor thrombus (both P<0.05). Furthermore, among the 184 patients with MRI diffusion-weighted imaging sequences, the patients with dampness-heat toxin amassment or Qi stagnation and blood stasis syndrome had significantly higher ADC values and relative ADC values than those with stagnation of liver Qi (all P<0.05). ConclusionThere are significant differences in CT/MRI radiological features and clinical features between PLC patients with different TCM syndrome types, among whom the patients with liver depression and spleen deficiency, dampness-heat toxin amassment, and liver-kidney Yin deficiency tend to exhibit progressive radiological features, and those with dampness-heat toxin amassment or Qi stagnation and blood stasis syndrome tend to have higher ADC values. These findings provide an objective basis for TCM syndrome differentiation in PLC.

Objective To establish a technical system for allogeneic kidney transplantation surgery in pigs using the Banna miniature pig inbred strain,and to evaluate it through routine blood tests,liver and kidney function tests,thus providing reference data for the preparation of allogeneic kidney transplantation models.Methods A total of 4 cases of allogeneic kidney transplantation surgeries were performed,including 1 case of single kidney transplantation in a healthy pig,2 cases of kidney transplantation after unilateral nephrectomy,and 1 case of kidney transplantation after bilateral nephrectomy.Before kidney transplantation,cross-matching and complement-dependent cytotoxicity(CDC)tests were used for matching between donor and recipient pigs.After kidney transplantation,peripheral blood samples were regularly collected from pigs for routine blood tests,liver function tests,and kidney function tests,and color Doppler ultrasound technology was used to detect blood supply to the transplanted kidneys.After reaching the experimental endpoint,both kidneys of pig DR1 and the left kidney of pig DR3 were collected and hematoxylin-eosin(HE)staining was performed to evaluate pathological changes in the transplanted kidneys.Results Recipient pigs DR1 and DR3 died at 17 days and 30 days after surgery respectively,while recipient pigs R and DR2 remained in good condition during the 30-day observation period.The results of liver and kidney function test showed that in pig DR1,alanine aminotransferase(ALT)levels increased on postoperative day 1(>1 000 U/L),peaked on postoperative day 7(1 300 U/L),and aspartate aminotransferase(AST)levels peaked on postoperative day 1(>3 000 U/L).On postoperative day 17,ALT and AST levels remained high(ALT,500 U/L;AST,700 U/L).In pigs R,DR2,and DR3,ALT and AST levels returned to normal around day 17.Serum creatinine(Crea)levels in pig R remained stable without postoperative increase.Crea levels in pigs DR1 and DR2 showed transient elevation on postoperative day 1,then gradually returned to normal(<100 μmol/L).Crea levels in pig DR3 remained below 500 μmol/L from postoperative days 2-10,but increased between days 11-28,reaching up to 1 500 μmol/L,indicating gradual loss of kidney function.Ultrasound results showed that the preoperative resistive index(RI)of recipient pig R was 0.91.On postoperative day 24,renal cortex and medulla showed abundant blood flow signals with RI value of 0.88,which was close to the pre-transplantation RI value.For pig DR2,the RI value on postoperative day 17 was 0.89,with poor renal cortex blood flow and relatively good renal medulla blood flow.In pig DR1 on postoperative day 17,no blood flow signals were detected in the transplanted kidney.HE staining results showed that the non-transplanted healthy right kidney of pig DR1 had normal structure,while the transplanted left kidney showed blurred glomerular structure and nuclear dissolution,indicating that the left kidney had lost function before removal.In the transplanted left kidney of pig DR3,large numbers of red blood cells and lymphocyte infiltration were observed in glomeruli and renal tubules,indicating possible coagulation dysfunction and rejection reactions after kidney transplantation.Conclusion Banna miniature pig inbred strain is used as experimental animals to perform four cases of allogeneic pig-to-pig kidney transplantation.The physiological parameters of the recipient pig and the function of the transplanted kidney are monitored after surgery using routine blood tests,liver and kidney function tests,color Doppler ultrasound,and pathological examinations.The allogeneic pig-to-pig kidney transplantation technical system established in the study can provide a foundation for clinicians to conduct kidney transplantation surgeries.

Corneal neovascularization(CNV)is a pathological condition characterized by the invasion of new blood vessels into the normally avascular corneal area from the corneal periphery,leading to severe vision loss and potentially blindness.Currently,surgical,physical,and pharmacological therapies are the main clinical approaches for treating CNV.Surgical treatment aims to remove abnormal vascular tissue or perform corneal trans-plantation to inhibit angiogenesis;however,it carries a risk of postoperative rejection.Physical therapy involves the direct application of non-invasive modalities,such as laser treatment,to the neovascularized area to suppress vascular growth.Nevertheless,this approach may cause damage to surrounding healthy tissues.Pharmacotherapy has recently become a research hotspot in CNV treatment due to its convenient administration.Clinically,the drugs used for CNV treatment mainly include anti-inflammatory agents,anti-VEGF drugs,and immunosuppressants,which inhibit CNV progression by targeting angiogenesis-related signaling pathways.However,these drugs often lead to drug resistance and toxic side effects.Therefore,there is an urgent need to develop more effective and safer therapeutic agents for CNV.This article reviews the current clinical treatment status of CNV and highlights recent advances in the use of small molecule extracts from traditional Chinese medicine for CNV therapy,aiming to provide potential candidate drugs and a scientific theoretical basis for clinical management of CNV.
