Clinicopathological features and expression of regulatory mechanism of the Wnt signaling pathway in colorectal sessile serrated adenomas/polyps with different syndrome types

BACKGROUND Colorectal cancer(CRC)is the third most common cancer worldwide,with the fourth highest mortality among all cancers.Reportedly,in addition to adenomas,serrated polyps,which account for 15%-30%of CRCs,can also develop into CRCs through the serrated pathway.Sessile serrated adenomas/polyps(SSAs/Ps),a type of serrated polyps,are easily misdiagnosed during endoscopy.AIM To observe the difference in the Wnt signaling pathway expression in SSAs/Ps patients with different syndrome types.METHODS From January 2021 to December 2021,patients with SSAs/Ps were recruited from the Endoscopy Room of Shanghai Traditional Chinese Medicine-Integrated Hospital,affiliated with Shanghai University of Traditional Chinese Medicine.Thirty cases each of large intestine damp-heat(Da-Chang-Shi-Re,DCSR)syndrome and spleen-stomach weakness(Pi-Wei-Xu-Ruo)syndrome were reported.Baseline comparison of the general data,typical tongue coating,colonoscopy findings,and hematoxylin and eosin findings was performed in each group.The expression of the Wnt pathway-related proteins,namelyβ-catenin,adenomatous polyposis coli,and mutated in colorectal cancer,were analyzed using immunohistochemistry.RESULTS Significant differences were observed with respect to the SSAs/Ps size between the two groups of patients with different syndrome types(P=0.001).The other aspects did not differ between the two groups.The Wnt signaling pathway was activated in patients with SSAs/Ps belonging to both groups,which was manifested asβ-catenin protein translocation into the nucleus.However,SSAs/Ps patients with DCSR syndrome had more nucleation,higherβ-catenin expression,and negative regulatory factor(adenomatous polyposis coli and mutated in colorectal cancer)expression(P<0.0001)than SSA/P patients with Pi-Wei-Xu-Ruo syndrome.In addition,the SSA/P size was linearly correlated with the related protein expression.CONCLUSION Patients with DCSR syndrome had a more obvious Wnt signaling pathway activation and a higher risk of carcinogenesis.A high-quality colonoscopic diagnosis was essential.The thorough assessment of clinical diseases can be improved by combining the diseases of Western medicine with the syndromes of traditional Chinese medicine.

Effect of the Haoqinqingdan decoction on damp-heat syndrome in rats with influenza viral pneumonia

Objective: To investigate the effect of Chinese medicine prescription-Haoqinqingdan decoction on damp-heat syndrome in rats with influenza viral pneumonia and its influence on the immune function. Methods: A total of 48 Wistar rats were randomly divided into the normal control group, the damp-heat syndrome model group, the Haoqinqingdan decoction group (high, medium and low dose group) and the ribavirin group. The body temperature and weight of rats in each group were recorded after modeling. After treatment for 6 d, the concentration of T lymphocyte subgroup (CD3+ CD4+ , CD3+ CD8+ ) was determined by flow cytometry. The OD value of IFN毭/IL-4 was detected by double-antibody sandwich ELISA method, and its concentration was acquired through conversion. Results: After modeling, the temperature and weight of rats in each modeling group showed the increasing trend ( P<0.01). From the second day of treatment, there was significant difference in the body mass between groups, and the rat weight of the control group was higher than in the modeling group ( P<0.05 or 0.01). With the advances of treatment, only the temperature in the medium and high dose Haoqinqingdan decoction groups declined significantly ( P<0.05). After treatment, the CD4+ /CD8+ ratio of the damp-heat syndrome model group decreased more significantly compared with the control group. Elevated CD3+ CD8+ percentages and declined CD4+ /CD8+ ratios can be observed in the low dose group and ribavirin group ( P<0.05). Moreover, the CD3+ CD4+ percentage of ribavirin group was lower than in the control group ( P<0.05). After treatment, the IFN-毭 and IFN-毭/ IL-4 levels in the peripheral blood of rats in the dampheat syndrome group were obviously higher than in the control group ( P<0.05). Conclusions: Compared with ribavirin, the high dose Haoqinqingdan decoction can improve the ratio of T lymphocyte subgroup and Th1/Th2 cell balance more effectively.

The role of endothelial biomarkers in predicting damp-heat syndrome in diabetic kidney disease

Objective:To explore the role of endothelial biomarkers in predicting damp-heat syndrome in diabetic kidney disease(DKD).Methods:A total of 183 patients with DKD were divided into 3 groups:the early DKD group,established DKD group,and advanced DKD group.All patients were classified according to traditional Chinese medicine(TCM)syndrome type,and clinical indexes were collected for statistical analysis.Results:A total of 183 DKD patients were included in this study.Fibroblast growth factor 23(FGF23),chitinase-3-like protein 1(CHI3L1),endocan,tumor necrosis factor receptor 1(TNFR1),secretory leukocyte protease inhibitor(SLPI),and vascular endothelial growth factor A(VEGF-A)were increased in advanced DKD.FGF23,CHI3L1,endocan,SLPI,and TNFR1 showed a negative correlation with estimated glomerular filtration rate(eGFR),while they had a positive correlation with 24 h urine protein.After adjusting for age,gender,diabetes duration,body mass index(BMI),hemoglobin,glucose,uric acid,24 h urine protein,cholesterol,triglyceride,low-density lipoprotein,and hemoglobin A1c(HbA1c),the multiple regression analysis showed that FGF23,endocan,TNFR1,and SLPI significantly correlated with eGFR.Conclusions:FGF23,endocan,TNFR1,and SLPI are elevated in advanced DKD compared with early stage,and they may take part in the pathogenesis and progression of DKD.Our study provides useful biomarkers for predicting the appearance of damp-heat syndrome,including FGF23,endocan,TNFR1,and SLPI.

Efficacy of Pidan Jianqing decoction in treatment of type 2 diabetes with spleen deficiency and damp-heat syndrome

Introduction:This study aimed to assess the clinical efficacy of Pidan Jianqing decoction in the treatment of type 2 diabetes.Methods:A total of 72 patients with type 2 diabetes differentiated as spleen deficiency with damp-heat syndrome were randomly assigned to a treatment group(n=35)or control group(n=32).Patients in the control group received diet and exercise guidance and medication in the form of 0.5 g metformin hydrochloride tablets,while patients in the treatment group received Pidan Jianqing decoction in addition to the treatment given to the control group.Efficacy was evaluated after 8 weeks of treatment.Results:Efficacy was 91.4%in the treatment group versus 68.8%in the control group,which was a statistically significant difference(P<0.05).Significant group differences were also noted in the number of patients with improvement in symptoms such as dry mouth and polydipsia,frequency of urination and polyuria,abdominal distention and loss of appetite,fatigue and weakness,and sticky stools(all P<0.05),with greater improvement in the treatment group compared to the control group.The fasting blood glucose(FBG)and 2 h postprandial blood glucose levels significantly improved in both groups after treatment(P<0.05);however,there was no significant difference in glycated hemoglobin levels before and after treatment in both groups.Conclusion:Pidan Jianqing decoction can lower blood glucose levels and improve symptoms in patients with type 2 diabetes.

Explanation of Gegen Qinlian Decoction Syndrome and Its Clinical Application

Gegen Qinlian Decoction is one of the commonly used classical prescriptions,which consists of fourherbs:Gegen(Puerariae Lobatae Radix),Huangqin(Scutellariae Radix),Huanglian(Coptidis Rhizoma),and Zhigancao Glycyrrhizae Radix et Rhizoma Praeparata cum Melle.The clinical application experience of Gegen Qinlian Decoction is as follows:first,according to Zhongjing Zhang's original text,heat distressing the large intestine with unresolved exterior syndrome is theoriginal meaningof Gegen Qinlian Decoction syndrome.In clinical practice,bacillary dysentery,gastrointestinal cold,etc.,belong to simultaneous exterior and interior disease,which are completely consistent with the original meaning of this prescription;second,the clinical digestive system diseases with exuberant heat of the large intestine as the core manifestation cannot be treated merely based on the exterior syndrome;third,due to the interior-exterior relationship between the lung and the large intestine and between the meridians,the use of Gegen(Puerariae Lobatae Radix),Huangqin(Scutellariae Radix),and Huanglian(Coptidis Rhizoma)can make the source of body clear,and the waste qi can be released and thepore can be easily opened,so this prescription can also be used for exogenous fever;fourth,with multidimensional comprehensive understanding of the syndrome,pathogenesis,symptoms and pharmacology,Gegen Qinlian Decoction has also been further applied to the treatment of hypertension,diabetes,etc.

从《伤寒论》少阳病证治特点探讨少阳半表半里说

“半表半里”一词虽未见于《伤寒论》,但“半表半里”之说源自其148条“半在里半在外”。其首见于《注解伤寒论》,随着后世医家的不断阐释发扬,半表半里学说对后世医家产生了重大影响。本文通过《伤寒论》相关文献梳理剖析,结合后世代表注家对半表半里的阐释,提出少阳病半表半里说不应从病位立论而当从病机立论,其内涵有二:一是少阳病经腑同病的病机特点即半表半里;二是少阳易与太阳、阳明、太阴合病或三阳合病即半表半里。

阳明病“胃家寒”当作“塞”解

“阳明之为病,胃家实(一作寒)是也”是阳明病的提纲证。基于训诂学,认为“寒”实为“塞”字讹误。在字形上,“寒”“塞”的隶楷字形极为相似,诸多出土文献皆有“寒”“塞”互讹的例子。在字义上,“塞”表达“充盈”“壅盛”“闭阻不通”,与阳明病的共性病机相符,故“胃家寒”实为“胃家塞”。此外,将“寒”作“塞”解,《伤寒论》第166条、176条等与“寒”相关的疑难条文皆可通。将“寒”作“塞”解,可为后续研究提供理论基础。

浅析表热里寒证

国家“十四五”规划教材《中医诊断学》对表热里寒证的论述较为简略,历代中医药学家对这一证型也争议颇多,导致医者对此类证候在理论和临床上有一些困惑和混淆,使得提取和界定证候要素存在一定的问题。文章从“表里”含义的不同角度“、寒热”概念中的不同界定等方面,结合古籍和历代医家对于表热里寒的理解,分析“表”和“里”的定义,浅析表热里寒证产生歧义的原因,以期加深在理论和临床上对本证型的理解。

Logistic Regression Analysis of Damp-Heat and Cold Damp Impeding Syndrome of Rheumatoid Arthritis:A Perspective in Chinese Medicine

Objective： To investigate a method for quantitative differential diagnosis of damp-heat and cold-damp impeding syndrome of rheumatoid arthritis （RA） in Chinese medicine （CM）. Methods： Laboratory parameters were collected from 306 patients with RA. The clinical symptoms and laboratory parameters were compared between patients with these two syndromes （158 with RA of damp-heat impeding syndrome, and 148 with RA of cold-damp impeding syndrome）, and a regression equation was established to facilitate discrimination of the two RA syndromes. Results： There were significant differences in disease activity score in 28 joints [DAS28 （4）], erythrocyte sedimentation rate （ESR）, white blood cell count （WBC）, C-reactive protein （CRP）, platelet count （PLT）, albumin （ALB） and globulin （GLB） between the two syndrome of RA （P〈0.05）. Logistic regression analysis showed that the parameters ESR, WBC, CRP, joint pyrexia, joint cold, thirst, sweating, aversion to wind and cold, and cold extremities were statistically useful to discriminate damp-heat from cold-damp impeding syndrome. The regression equation was as follows： P=1/{1＋exp[-（3.0-0.021X1-0.196X2-0.163X3- 1.559X4＋1.504X5-0.927X6-1.039X7＋1.070X8＋1.330X9）]}. The independent variables X1-X9 were ESR, WBC, CRP, hot joint, cold joint, thirst, sweating, aversion to wind and cold, and cold limbs. A P value 〉 0.5 signified cold-damp impeding syndrome, and a P value 〈 0.5 signified damp-heat impeding syndrome. The accuracy was 90.2%. Conclusion： The regression equation may be useful for discriminating damp-heat from cold-damp impeding syndrome of RA.
