TCM believes that the main pathogenesis of gastrointestinal dysfunction (GD) after laparoscopic cholecystectomy (LC) is spleen and stomach weakness, liver and stomach disharmony, liver depression and spleen deficiency, and intestinal depression. Moxibustion in the treatment of GD after LC can avoid the aggravation of gastrointestinal burden caused by oral drugs. The intervention methods mainly include suspension moxibustion, umbilical moxibustion, heat sensitive moxibustion, thunder fire moxibustion, warm acupuncture, partition moxibustion, etc. Moxibustion is often performed on the acupoints in liver meridian, spleen meridian, stomach meridian, small intestine meridian, large intestine meridian and Conception Vessel, such as Taichong (LR3), Ganshu (BL18), Yinlingquan (SP9), Zusanli (ST36), Tianshu (ST25), Wangu (SI4), Hegu (LI4), Zhongwan (CV12), Shenque (CV8) and Qihai (CV6). At present, most studies combined with moxibustion on the basis of conventional Western medicine treatment can significantly improve the efficacy, and have certain advantages in improving gastrointestinal motility decline, intestinal flora imbalance, first exhaust time, gastrointestinal hormone level disorder and intestinal mucosal barrier dysfunction. However, there are still some problems in the existing research: small sample size of clinical research, not perfect scoring scale, not unified treatment plan and operation standard, relatively scarce basic research, relatively simple acupoint research, lack of biochemical evaluation indicators, and the research of national moxibustion needs to be explored and improved in the future.

Objective:To explore the medication law of TCM external therapy for the treatment of diabetic foot using data mining methods.Methods:Literature on TCM external treatment for diabetic foot was retrieved from CNKI, Wanfang Data, and Chongqing VIP from the establishment of the databases to June 30, 2024. Excel 2019 software was used to conduct frequency statistics on drug frequency, properties, tastes and meridian tropism, drug efficacy, and commonly used drug pairs. Ancient and Modern Medical Cases Cloud Platform V3.5 was used for association rules, and SPSS Statistics 27.0 was used for complex network analyses.Results:A total of 425 articles were included, involving 328 prescriptions and 232 drugs. The drugs with higher frequency were Carthami Flos, Angelicae Sinensis Radix, Cinnamomi Ramulus, Olibanum, etc. The main tastes were pungent, bitter, and sweet; the main properties were cold and warm; the main meridians were heart, spleen, and liver meridians. The main efficacy was promoting blood circulation and removing blood stasis, clearing heat, and tonifying deficiency; association rule analysis obtained 20 commonly used drug pairs; clustering analysis resulted in four core drug combinations; complex network analysis led to one core prescription.Conclusions:TCM external therapy for diabetic foot follows the guiding principles of "promoting blood circulation and unblocking collaterals, tonifying deficiency and clearing heat" with coordinated regulation of the "heart-liver-spleen meridians". The core prescription and stage-specific formulation strategies reflect a trinity diagnostic and therapeutic approach of "disease differentiation-syndrome differentiation-stage differentiation", providing valuable reference and insights for clinical prescription practices.

Objective To investigate the clinical features of patients with recurrent acute pancreatitis(RAP)complicated with metabolic syndrome(MS)and the influencing factors of severe disease.Methods The clini-cal data of 382 RAP patients admitted to the hospital from June 2012 to June 2022 were retrospectively analyzed,and they were divided into the MS group(n=142)and the non-MS group(n=240)according to whether they were combined with MS,and into the severe group(n=29)and the non-severe group(n=353)according to the severity.The general data,serological parameters[triglyceride(TG),total cholesterol(TC),white blood cell count(WBC),neutrophil to lymphocyte ratio(NLR),blood calcium,D-dimer(D-D),lactate dehydrogen-ase(LDH),ALT,AST]and ICU occupancy rate and total length of stay were compared among all groups.Bi-nary logistic regression was used to analyze the independent influencing factors of RAP development into se-vere disease,and receiver operating characteristic(ROC)curve was used to analyze the predictive value of each indicator for RAP development.Results Hyperlipidemia was the most common cause of RAP in MS group(66.2％),and biliary origin was the most common cause of RAP in non-MS group(44.6％).There was sig-nificant difference among different causes was statistically significant(P＜0.05).There were significant differences in age,gender,proportion of hypertension,diabetes,MS,length of stay,LDH,blood calcium,D-D and NLR levels between the critical and non-critical groups(P＜0.05).The area under the curve(AUC)of blood calcium,D-D,LDH,NLR and combined diagnosis were 0.759,0.777,0.710,0.621,and 0.841,respec-tively.The AUC of single diagnosis had a certain predictive value,but combined diagnosis had a higher predic-tive value.Conclusion The most common cause in the MS group was hyperlipidemia,and the most common cause in the non-MS group was biliary.Blood calcium.D-D,LDH,NLR are reliable indicators to predict the development of RAP into severe disease,and the accuracy of combined diagnosis is higher.

Ceruloplasmin(Cp)is a crucial protein secreted by the liver and plays a vital role in regulating the distribution and transport of copper throughout the body,thereby maintaining copper homeostasis.Additionally,Cp functions as a significant enzyme known as ferroxidase,which is involved in iron metabolism within the body.Numerous studies have suggested a close relationship between Cp and metabolic disorders,such as diabetes and cardiovascular diseases.Recent research has also shed light on the involvement of Cp in the regulation of lipid metabolism.The various activities associated with lipid metabolism,including lipid synthesis,adipose hydrolysis,fatty acid oxidation,lipid transport,and absorption,collectively contribute to maintaining lipid homeostasis.Dysregulation of lipid metabolism can lead to metabolic disorders and cardiovascular complications.Cp regulates lipid metabolism through two main mechanisms.Firstly,Cp participates in the regulation of oxidative stress by modulating iron metabolism through its ferroxidase activity and involvement in redox reaction.Secondly,copper along with copper-dependent enzymes directly participates in the processes such as cholesterol metabolism,lipoprotein metabolism,and fatty acid synthesis.As a result,the role of Cp in maintaining the homeostasis of copper and iron allows it to regulate lipid metabolism by influencing copper or iron-dependent enzymes and related pathways.Although the correlation between Cp and lipid metabolism has been identified,an in-depth exploration of the precise mechanisms by which Cp governs lipid metabolism is warranted.This article provides an overview of the role of Cp in lipid metabolism and highlights the progress in related research,with the aim of providing new insights for the development and treatment of disorders related to lipid metabolism.

【Objective】 To explore the clinical features of dermatomyositis and diagnostic value of MRI. 【Methods】 The clinical and imaging data of 61 patients with dermatomyositis were analyzed retrospectively. 【Results】 Among the 61 patients， there were 15 males and 46 females with the average age of 45.3 years. The course of disease was 10 days to 12 years. All of them had different degrees of skin lesions， including 57 cases of myasthenia and or myalgia， 4 cases of dysphagia， 2 cases of dyspnea， and 2 cases of drinking water and coughing. There were 18 cases complicated with interstitial lung disease， 1 case complicated with Sjogren’s syndrome， 1 case complicated with arthritis， 1 case complicated with rhabdomyolysis， and 1 case complicated with kidney damage and liver insufficiency. MRI examination performed in 46 patients with dermatomyositis detected 43 cases of abnormal manifestations， 41 cases of muscle inflammatory edema， 37 cases of subcutaneous adipose tissue edema， and 40 cases of myofascitis. 【Conclusion】 The clinical manifestations of dermatomyositis are complex and have certain imaging features. Combined with the laboratory examinations of muscle enzymes and autoantibodies， electromyography， skin and muscle biopsy， they can provide clinical diagnostic evidence. MRI is an important means to diagnose and evaluate the extent and progression of dermatomyositis.

【Objective】 To screen nucleic acid aptamers that can specifically recognize castration-resistant prostate cancer （CRPC） cells by Cell-SELEX. 【Methods】 For Cell-SELEX selection， CRPC cell lines C4-2 were used as positive control cells， while androgen-dependent prostate cancer cell lines LNCap were used as negative control cells. The 5’end of the upstream primers was labeled with FITC， and the 5’end of the downstream primers was labeled with biotin. Single-stranded DNA （ssDNA） collected from each round of screening was used as template for PCR amplification and purification. The biotin-streptavidin magnetic bead separation was used to isolate PCR product for the next round of screening. The process of Cell-SELEX was analyzed by flow cytometry. ssDNA products of the last round were collected for PCR amplification， purification， cloning and DNA sequencing. The secondary structure of selected DNA aptamers was predicted. Dissociation constants of the two aptamers were calculated. Flow cytometry and confocal microscopy were used to evaluate selective binding of aptamers to CRPC cells and tissues. 【Results】 The binding rate of DNA products to CRPC cells gradually increased with the increase of selection cycles， reaching the highest in the last round. DNA structure prediction analysis showed that the secondary structure of aptamers CRPC-1 and CRPC-2 was mainly stem-loop structure. Flow cytometry analysis and confocal images showed that both CRPC-1 and CRPC-2 could specifically target C4-2 cells. In addition， immunohistofluorescence assay showed that CRPC-1 could specifically target CRPC tissues. 【Conclusion】 Cell-SELEX can be used to screen aptamers that specifically target CRPC cells and tissues， which provides experimental basis for early screening and targeted diagnosis of CRPC. It is of significance for treatment plan adjustment and prognosis improvement of prostate cancer.

Objective To explore the clinical value of magnetic resonance time-resolved imaging of contrast kinetics (MR-TRICKS)in the assessment of lower extremity venous lesions in Klippel-Trenaunay syndrome (KTS).Methods Image data of 20 patients (total 21 affected limbs)diagnosed with KTS in our hospital were analyzed retrospectively.All patients underwent MR-TRICKS angiography and ascending phlebography of the lower extremities.The images acquired by these two methods were graded and compared.Kappa test was used to examine the consistency between the results of two inspection methods.Results The image quality of MR-TRICKS angiography and ascending phlebography graded on excellent proportion were 85.71％(18/21)and 80.95％(17/21)for the deep veins,95.24％(20/21)and 90.48％(19/21)for the superficial veins,and 90.48％(19/21)and 85.71％(18/21) for venous malformation,respectively.MR-TRICKS demonstrated that the deep veins were normal in 61.90％ (13/21),hypogenetic in 25.57％(7/21),atretic in 4.86％(1/21).Superficial vein diseases including varicosis of the great saphenous vein accounted for 25.57％(6/21), varicosis of the small saphenous vein accounted for 14.29％ (3/21 ),while marginal veins in venous malformation accounted for 100％ (21/21).Ascending phlebography of the lower limbs showed that the deep veins were normal in 57.14％(12/21)and dysplasia in 39.10％(8/21),while the other results were consistent with those of TRICKS.Consistency between results from the two methods were excellent (Kappa >0.75).Conclusion MR-TRICKS can accurately describe the angioarchitecture of the lower extremity vena in patients with KTS,and has an important clinical value in providing support for the assessment and treatment of KTS.
