To summarize Professor WANG Jianmin's experience in cathartic colon from "keeping sweet to return liquid". It is believed that the key to the pathogenesis of cathartic colon is fluid consumption and intestinal dryness， including yin depletion of spleen earth， and lack of sources for body fluids production； discordance of water and fire in kidneys， and irregular distribution of body fluids； and closure of the lungs and liver leads to inability of the flow of fluids. The treatment is based on the principle of "keeping sweet to return liquid"， using sweet medicinals mainly， assistant with sour， bland and acrid medicinals， and self-prescribed Lipi Shengjin Decoction （理脾生津汤）， Wenshen Runchang Decoction （温肾润肠汤）， Kaifei Shunchang Decoction （开肺顺肠汤）， Rougan Tongbian Decoction （柔肝通便汤） could be used to regulate spleen yin by the sweet and bland， and establish qi and promote fluid production； the sweet and warm medicinals can replenish water and fire， transform into qi， and distribute body fluids； the acrid and sweet can open lung depression， descend qi， and flow the body fluids； the sour and sweet can emolliate liver， move qi， and transform fluids.

Objective To prepare a nano drug(PFOB@Lip-MMC)with liposome as the carrier,liquid perfluorooc-tyl bromide(PFOB)as core and mitomycin C(MMC)loading on the liposome shell and study its inhibitory effect on the proliferation of human pterygium fibroblasts(HPFs).Methods The thin film dispersion-hydration ultrasonic method was used to prepare PFOB@Lip-MMC and detect its physical and chemical properties.Cell Counting Kit-8,Cam-PI cell viability staining and flow cytometry were employed to detect the impact of different concentrations of PFOB@Lip-MMC on the via-bility of HPFs.DiI fluorescence labeled PFOB@Lip-MMC was used to observe the permeability of the nano drug to HPFs under a laser confocal microscope.After establishing HPF inflammatory cell models,they were divided into the control group(with sterile phosphate-buffered saline solution added),PFOB@Lip group(with PFOB@Lip added),MMC group(with MMC added),PFOB@Lip-MMC group(with PFOB@Lip-MMC added)and normal group(with fresh culture medi-um added)according to the experimental requirements.After co-incubation for 24 h,flow cytometer was used to detect the apoptosis rate of inflammatory cells,and the gene expression levels of interleukin(IL)-1β,prostaglandin E2(PGE2),tumor necrosis factor(TNF)-α and vascular endothelial growth factor(VEGF)in cells were analyzed by PCR.Results The average particle size and Zeta potential of PFOB@Lip-MMC were(103.45±2.17)nm and(27.34±1.03)mV,respec-tively,and its entrapped efficiency and drug loading rate were(72.85±3.28)％and(34.27±2.04)％,respectively.The sustained-release MMC of drug-loaded nanospheres reached(78.34±2.92)％in vitro in a 24-hour ocular surface environ-ment.The biological safety of PFOB@Lip-MMC significantly improved compared to MMC.In terms of the DiI fluorescence labeled PFOB@Lip-MMC,after co-incubation with inflammatory HPFs for 2 h,DiI fluorescence labeling was diffusely dis-tributed in the cytoplasm of inflammatory HPFs.The apoptosis rate of inflammatory HPFs in the PFOB@Lip-MMC group[(77.23±4.93)％]was significantly higher than that in the MMC group[(51.62±3.28)％].The PCR examination results showed that the gene transcription levels of IL-1 β,PGE2,TNF-α and VEGF in other groups were significantly reduced com-pared to the control group and PFOB@Lip group,with the most significant decrease in the PFOB@Lip-MMC group(all P＜0.05).Conclusion In this study,a novel nano drug(PFOB@LIP-MMC)that inhibited the proliferation of HPFs was successfully synthesized,and its cytotoxicity was significantly reduced compared to the original drugs.It has good bio-compatibility and anti-inflammatory effects,providing a new treatment approach for reducing the recurrence rate after pte-rygium surgery.

Objective To investigate the correlation between serum C1q/tumor necrosis factor related protein 9(CTRP9)and soluble CD146(sCD146)levels and coronary artery lesions(CAL)in children with Kawasaki disease(KD).Methods A total of 116 children with KD admitted to the People's Hospital of Kaizhou District,CQ from October 2020 to February 2023 were selected as the study subjects(KD group).According to the ultrasound diagnosis results,children with KD were grouped into CAL group(n=40)and non CAL group(n=76).According to the severity of CAL,children with KD in the CAL group were separated into mild group(n=14),moderate group(n=18)and severe group(n=8).Enzyme linked immunosorbent assay(ELISA)was applied to measure serum levels of CTRP9 and sCD146.The differences in serum levels of CTRP9 and sCD146 in control group,CAL group,non CAL,and children with different severity of CAL were compared.Multiple Logistic regression was applied to analyze the factors affecting the occurrence of CAL in children with KD.Receiver operating characteristic(ROC)curve was applied to analyze the predictive value of serum CTRP9 and sCD146 levels for the occurrence of CAL in KD children.Results Compared with the control group,the serum CTRP9 level in the KD group was decreased(3.27±0.27ng/ml vs 3.79±0.91ng/ml),while the sCD146 level was increased(191.28±50.39 ng/ml vs 143.97±38.29 ng/ml),with significant differences(t=5.900,8.051,all P＜0.05).The serum CTRP9 level in the CAL group was lower than that in the non CAL group(3.01±0.23ng/ml vs 3.41±0.29 ng/ml),but the sCD146 level was higher than that in the non CAL group(232.18±59.37 ng/ml vs 169.76±45.66 ng/ml),with significant differences(t=7.557,6.294,all P＜0.05).Compared with the mild group,the serum CTRP9 level in the moderate and severe groups was decreased(q=3.277,6.281),with sCD146 level increased(q=3.154,5.551),the serum CTRP9 level in the severe group was lower than that in the moderate group(q=3.845),with sCD146 level was higher than that in the moderate group(q=3.145),and the differences were statistically significant(all P＜0.05).The results of multivariate logistic regression analysis showed that white blood cell count(WBC),erythrocyte sedimentation rate(ESR),C reactive protein(CRP),CTRP9 and sCD146 were all influencing factors for the occurrence of CAL in children with KD(all P＜0.05).The results of ROC curve showed that the AUCs of CTRP9 and sCD146 separately predicted the occurrence of CAL in KD children were 0.781 and 0.782,with sensitivity of 82.5％and 67.5％,and specificity of 52.2％and 55.7％,respectively.The AUC for the combined diagnosis of CAL in children with KD was 0.889,with sensitivity and specificity of 97.5％and 65.9％,respectively.Conclusion Serum CTRP9 and sCD146 were influencing factors for the occurrence of CAL in children with KD,and the level of CTRP9 was decreased,while sCD146 was increased in the serum of children with CAL.The combination of the two can effectively predict the occurrence of CAL in children with KD.

Pathological mechanism of ulcerative colitis(UC)is not fully clear,which may be the result of Th17/Treg immune imbalance and the interaction of multiple complex factors.Numerous studies have found that classical TCM prescriptions,experienced formulas and TCM active components could regulate Th17/Treg balance by intervening in cytokines,transcription factors,and signaling pathways,restore intestinal mucosal immune function,suppress intestinal mucosal inflammatory response,and repair intestinal mucosal barrier damage.Based on the research status of UC,Th17/Treg balance and TCM treatment,this article reviewed the relationship between Th17/Treg balance and UC,and explained the key role of Th17/Treg balance in the occurrence and development of UC.At the same time,the Chinese materia medica targeting to regulate the balance of Th17/Treg in the treatment of UC in recent years was summarized,in order to provide reference for the treatment of UC.

Objective Recently, The incidence of fatty liver is increasing , with the improvement of people′s living standard. We here established an available model with non-alcoholic fatty liver disease in rabbits and then studied its sonographic findings . Methods Forty male Japanese rabbits were randomly divided into 2 groups:control group and model group.The rabbits in model group were fed with high-fat diet for the establishment of the model of non-alcoholic fatty liver disease.The rabbits in control group were fed with standard diet. At the baseline, 12th, 16thand 20th week , all the livers in 2 groups were scanned by ultrasonography, and at the end of 20 th week, all the rabbits in 2 groups were killed for pathological analysis. Results Both the ultrasonography and in pathology demonstrated the successful establishment of non-alcoholic fatty liver models.The result of study demonstrated significant differences (P<0.05).At the 12th week, all of the 19 livers in model group showed fatty livers in sonography:8 low-, 9 middle-and 2 high-grade.The degree of steatosis aggravated pro-gressively with modeling time.Most of livers showed middle-grade fatty at the 16th week, and at the 20th week, they all demonstrated middle-or high-grade fatty liver:10 middle-and 9 high-grade, furthermore, ascites occurred in 3 cases.The pathological results were consistent with the findings of sonography, and fibrosis were observed in pathology. Conclusion Animal model with non-alcoholic fatty liver disease in rabbits can be established by high-fat diet.Besides, ultrasonography is a good method to monitor the establishment of the model .

Objective The incidence of alcoholic fatty liver increases year by year in recent years .The aim of this study was to establish an animal model of AFL to investigate the pathogenesis of hepatic fibrosis . Methods This study involved 40 male Japa-nese rabbits aged (17.01 ±1.54) d and weighing 1.00-1.52 kg, which were equally randomized to an experimental group and a control group.The animals in the former group received lavage of 10 mL of 50%ethanol twice a day, with normal feedstuff and water, while those in the control group received normal feedstuff and water only .We performed ultrasonography for dynamic liver presentation before and at 12, 16, and 20 weeks after feeding, followed by pathological observation of the livers . Results After 12 weeks of eth-anol garage , fatty liver was observed in 18 of the rabbits and it deteriorated with the prolonged time of administration . The body weight was significantly decreased in the experimental rabbits as com-pared with the controls at 16 weeks ([2.48 ±0.30] vs [2.78 ± 0.15] kg, P<0.05) and 20 weeks ([2.61 ±0.44] vs [3.10 ± 0.13] kg, P<0.05).Ultrasound and pathological grading showed 1 mild, 3 moderate, and 13 severe cases of fatty liver in the experimen-tal group, but none in the control , and pathological examination re-
vealed similar results (1 mild, 4 moderate, and 12 severe cases of fatty liver) in the former group.At 20 weeks, alcoholic fatty liver was found mainly in the S3-S4 stage. Conclusion Alcoholic fatty liver models could be successfully established in rabbits by etha-nol garage and ultrasonography is useful for monitoring the development and progression of the condition .
