Objective:To investigate the efficacy of treatment of primary hepatic carcinoma by three different interventional theraputic methods.Methods:121 cases with moderate and advanced stages of HCC were treated with PEI +LP-TAE,chemoembolization,LP,and SLPGSTAE respectively.All cases were divided into two groups according to the tumor’s size:group A(＞8 cm)and group B(≤8 cm).The efficacy and survial incidence of the three different methods were analyzed.Results:62 of the 76 cases(81%)in group A and 16 of the 45 cases(35.5%)in group B were decreased in size after the same theraputic method,two groups had statistically significant (P＜0.01).In group A,9 cases treated with chemoembolization and LP were invalid.16 of the 36 cases became smaller after SLPGSTAE.The 1,2 and 3 year surval incidence of patients in group B were 77.6%、42.1%、18.4% respectively as compared with group A were 68.8%、40.0%、11.1%.Conclusion:PEI can cause small tumors to form nerosis,SLPGSTAE cn play dual embolization role and had no servious damage to liver function.

Cocaine,as a widely abused and highly addictive drug,has a serious impact on the physical and mental health of individuals and carries a certain degree of social harm and economic burden.Acupuncture can assist in the treatment of cocaine addiction with fewer side effects.However,a well-defined mode of stimulation is an important factor in elucidating the various mechanisms by which acupuncture treats disease.This paper summarizes the problems in the mechanism of cocaine addiction,such as different parameters of stimulation,unstable depth of acupuncture,different acupoint selection,and different lengths of acupuncture time.To standardize the intervention measures of acupuncture experiments,it is suggested that in future research,the stimulation method should explore the best parameters,the selection of acupoints should be based on clinical practice,the timing of acupuncture should be objective,and the treatment course should consider the effects of acupuncture.

Gastric ulcer is a common digestive system disease,and the long-term use of non-steroidal anti-inflammatory drugs(NSAIDs)is the second most important cause.NSAID-induced gastric ulcer animal models are key experimental tools for studying the pathogenesis,corresponding treatment method,and effective mechanisms of NSAID-induced gastrointestinal injury.However,there are currently a lack of reviews on NSAID-induced gastric ulcer animal models.This review summarizes and compares the relevant literature on animal research into indomethacin-and aspirin-induced gastric ulcers in the past 10 years,including the selection of experimental animals,drug solvents,and specific modeling method.The limitations of current models,such as the cumbersome modeling method,incomplete modeling details,inadequate models for clinical use,and lack of comparative drug research,are discussed.Feasible solutions are proposed with the aim of providing an effective reference for research in this field.

In heterologous protein productions by Pichia pastoris, methanol induction is generally initiated when cell density reaches very high level. However, this traditional strategy suffers with the problems of difficulty in DO control, toxic by-metabolites accumulation and low targeted protein titer. Therefore, initiating methanol induction at lower cell concentration is considered as an alternative strategy to overcome those problems. However, the methanol/energy regulation mechanisms of initiating induction at lower concentration are not clear and seldom reported. In this article, with monellin production as a prototype, we analyzed the methanol/energy metabolism in protein expression process using the strategies of initiating induction at both higher/lower cells concentrations. We attempted to interpret the advantages of the "alternative" strategy, via online measurements of methanol consumption, CO₂ production and O₂ uptake rates. When adopting this "alternative" strategy and maintaining temperature at 30 °C, carbon flux ratio directing into monellin precursors synthesis reached the highest level of 65%. In addition, monellin synthesis was completely associated with cell growth.

ObjectiveBased on literature data mining， this study explores the modeling elements of diarrhea-predominant irritable bowel syndrome （IBS-D） animal models in China and abroad， providing references and suggestions for improving modeling methods and evaluation indicators. MethodsRelevant literature on IBS-D animal experiments from 2014 to 2024 was retrieved through computer searches in databases such as China National Knowledge Infrastructure （CNKI）， Wanfang Data， VIP， Chinese Medical Journals Full-text Database， and PubMed. Information on experimental animal species， gender， body weight， modeling methods， modeling periods， intervention controls， modeling standards， and detection indicators was organized. Microsoft Excel 2021 software was used to establish a database and perform statistical analysis to examine the characteristics of IBS-D animal models. ResultsA total of 398 articles that met the inclusion criteria were reviewed. The IBS-D animal models were predominantly established using SD rats， Wistar rats， and C57BL/6 mice. Male animals were more commonly used， with rats typically aged 6-8 weeks and mice aged 4-6 weeks. In terms of interventions， piverium bromide was the main Western medicine， Tongxieyaofang was the primary Chinese medicine， and electroacupuncture was the primary acupuncture method. Among the modeling methods， the multi-factor combined composite modeling approach was the most common. Modeling periods were mainly concentrated between 1-14 days and 15-30 days. The success criteria for modeling were mainly evaluated based on the animal's general condition， fecal appearance， visceral sensitivity， gastrointestinal motility， behavior， and pathology. Detection indicators included apparent indexes， pathological markers， biochemical indicators， oxidative stress， brain-gut peptides， neurotransmitters， inflammatory factors， immune function， intestinal permeability， autophagy， apoptosis， proteins related to relevant signaling pathways， intestinal microbiota and its metabolites， etc. ConclusionThere are various methods for establishing IBS-D animal models， but no unified and universally accepted method has been established. The operation of the same modeling methods and the evaluation standards of the models vary across studies. Based on the results of data mining， the authors suggest that the multi-factor combined composite modeling approach most closely reflects the pathophysiological processes of IBS-D， better simulating the complex clinical symptoms of IBS-D patients， such as abdominal pain and diarrhea， and has a high degree of clinical relevance. This method is relatively recommended. While animal models in general align with Western medicine standards， models incorporating traditional Chinese medicine （TCM） syndromes are relatively few. Therefore， one of the future directions for research is to establish IBS-D animal models that meet the combined clinical disease and syndrome requirements of both Western and Chinese medicine.

【Objective】 To analyze the frequency and profile of irregular antibodies in different ethnic groups through screening and identification of irregular antibodies in 67 552 blood recipients in the Affiliated Hospital of Guizhou Medical University. 【Methods】 Irregular antibody screening was carried out in patients with different ethnic groups from August 1, 2016 to July 31, 2019 by microcolumn gel anti human globulin method, and the irregular antibody specificity were identified by panel cells. 【Results】 1)307 out of 67 552 cases were positive for irregular antibody, with the positive rate at 0.45%(307/67 552). Among them, Chuanqing was 1.27%(6/473), Yi 1.15%(4/348), Buyi 1.03%(10/975), Dong 0.58%(3/514), Han 0.44%(273/62 365), Miao 0.42%(5/1 187) and Tujia 0.34%(2/596), with significant differences among nationalities. Irregular antibody detection: the positive rate of female patients(0.56%, 223/41 359) was higher than that of male patients(0.32%, 84/26 193)(P<0.05). The positive rate of patients transfused before(1.22%, 129/10 553) was higher than non-transfusion patients(0.31%, 178/56 999)(P<0.05). The positive rate of female patients with pregnancy history(0.52%, 192/37 176) was higher than non-pregnancy females(0.17%, 7/4 183)(P<0.05). The positive rate increased with age, without any significant differences(P>0.05). The yields of irregular antibodies did not differ by ABO blood groups(P>0.05). 3)The specificity of 307 irregular antibody positive cases involved 7 blood group systems, including Rh system 59.28%(182/307), MNSs system 9.12%(28/307), Kidd system 0.65%(2/307), Duffy system 0.98%(3/307), Lewis system 5.86%(18/307), P system 0.65%(2/307), and Digeo system 0.33%(1/307). In addition, 15.64%(48/307) of autoantibodies, 0.65%(2/307) of cold antibodies and 4.93%(15/307) of unclear antibodies were detected. 4)The distribution of anti-D, anti-C and autoantibodies were statistically significant among the Han, Buyi, Chuanqing, Miao, Yi and Dong nationalities(P<0.05), while the others were similar(P>0.05). 【Conclusion】 The distribution of irregular antibodies in Guizhou is different by nationalities. Routine screening of irregular antibodies for transfused or pregnant patients can increase the safety and efficacy of blood transfusion. Most of the irregular antibodies detected are Rh blood group system. The exposure to irregular antibodies can be reduced by additional detection of blood group antigen other than RhD for blood recipients and donors, as well as the blood transfusion with matched blood group antigens.
