Correlation of serum glutamate and gamma-aminobutyric acid levels with clinical symptoms in chronic schizophrenia patients and their diagnostic value for cognitive impairment / 国际检验医学杂志

Objective To explore the correlation of serum glutamate(Glu)and gamma-aminobutyric acid(GABA)levels with clinical symptoms in chronic schizophrenia patients,and to assess their diagnostic value for cognitive impairment.Methods A total of 92 patients with chronic schizophrenia and another 80 healthy individuals in Wuhan Mental Health Center/Wuhan Hospital for Psychotherapy from January 2021 to July 2022 were enrolled as study group and control group,respectively.The patients in the study group were divid-ed into the cognitive impairment group(44 cases)and the cognitive normal group(48 cases)according to Montreal Cognitive Assessment Scale(MoCA).Clinical symptoms were assessed by using Positive and Nega-tive Syndrome Scale(PANSS).MoCA was used to evaluate the cognitive function.The levels of Glu and GA-BA in plasma were determined by high-performance liquid chromatography/electrospray tandem mass spec-trometry.The scores of PANSS and MoCA as well as serum levels of Glu and GABA were compared between two groups.Then the correlation of serum Glu and GABA levels with clinical symptoms and the diagnostic value for cognitive impairment in the patients in the study group were investigated.Results The Glu level in the study group was higher than that in the control group,and the GABA level was lower than that in the con-trol group(P＜0.05).The serum Glu levels in both the cognitive impairment group and the cognitive normal group were higher than the normal range,and the Glu level in the cognitive impairment group was higher than that in the cognitive normal group(P＜0.05).The serum GABA levels in both the cognitive impairment group and the cognitively normal group were lower than the normal range,and the GABA level in the cogni-tive impairment group was lower than that in the cognitive normal group(P＜0.05).In the study group,ser-um Glu level was positively correlated with negative,positive,general psychopathological symptom scores,and overall score in PANSS(P＜0.05),while GABA level was negatively correlated with negative,positive,gener-al psychopathological symptom scores,and overall score in PANSS(P＜0.05).The sensitivity of the single and combined detection of serum Glu and GABA for the diagnosis of cognitive impairment in patients with chronic schizo-phrenia was 77.3％,72.7％and 93.2％,respectively,and the specificity was 72.9％,72.9％,and 75.0％,respec-tively,and the area under the curve was 0.778,0.769,and 0.868,respectively.Conclusion Serum Glu level in patients with chronic schizophrenia is higher than that in healthy individuals,while GABA level is lower than that in healthy individuals,and the above two indicators are correlated with PANSS score,which have high value in diagnosing cognitive impairment and could be used as effective biological indicators to help clinical doctors judge patients'cognitive function.

Relationship between metabolites of peripheral tryptophan-kynurenine metabolic pathway and clinical symptoms in patients with schizophrenia / 四川精神卫生

BackgroundSchizophrenia is a common severe mental disorder with complex pathogenesis. There are few studies on the correlation between kynurenine metabolites in peripheral serum and urine in schizophrenia. ObjectiveTo investigate the concentration of tryptophan-kynurenine metabolites and interleukin-6 （IL-6） in serum and urine in patients with schizophrenia， and their correlation with clinical symptoms， so as to explore potential biological characteristics related to schizophrenia. MethodsA total of 38 patients with schizophrenia who met the criteria of the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5）， and were hospitalized or attended outpatient clinic at Hangzhou Seventh People's Hospital from December 2021 to December 2022 were included in the study. Additionally， 26 healthy individuals were concurrently recruited from the community of Hangzhou to serve as a control group. All participants were requested to complete the Positive and Negative Symptom Scale （PANSS）. The levels of tryptophan （TRP）， kynurenine （KYN）， kynurenic acid （KYNA）， quinolinic acid （QUIN）， picolinic acid （PIC）， xanthurenate and 5-hydroxytryptamine （5-HT） in both serum and urine were measured using ultra-high-performance liquid chromatography-triple quadrupole linear ion trap mass spectrometry. Serum and urine IL-6 were measured using enzyme-linked immunosorbent assay. Pearson correlation analysis was conducted to examine the correlation between serum and urinary KYN metabolites， as well as the correlation between metabolite levels and clinical symptoms in the patient group. ResultsPatients with schizophrenia had significantly higher level of IL-6 in serum （U=798.500， P<0.01） and lower level of PIC in urine （U=253.000， P=0.013） compared with the control group. Additionally， level of serum KYN was positively correlated with QUIN/KYNA ratio and QUIN/PIC ratio （r=0.562， 0.438， P<0.05） in patients with schizophrenia. 5-HT/KYN ratio in serum was positively correlated with PANSS total score and negative symptom subscale score （r=0.458， 0.455， P<0.01） in patients with schizophrenia. ConclusionSerum TRP-KYN pathway metabolite levels in patients with schizophrenia were associated with neurotoxic metabolite ratios in urine and the severity of negative symptoms. ［Funded by Zhejiang Medical and Health Science and Technology Program Exploratory （number， 2022KY990）］

Objective:To understand the effects of paliperidone palmitate (PP) long-acting injection on hospitalization, psychiatric symptoms, individual and social function of community patients with schizophrenia.Methods:From March 2021 to September 2022, 239 patients with schizophrenia in the community of Zhongshan city were treated with PP injection in a 1-month dosage form for 1 year.The hospitalization rate was compared before and after the treatment.The brief psychiatric rating scale (BPRS), modified overt aggression scales(MOAS), clinical global impressions-severity(CGI-S), and personal and social performance scale (PSP) were used to evaluate psychiatric symptoms and personal social function at baseline, at the end of the 8th week, the end of the 6th month and the end of the 12th month after treatment.Repeated measurement analysis of variance was used to compare the results at different times of treatment, and Logistic regression analysis was used to analyze the factors affecting treatment by SPSS 26.0.Results:One year after treatment the number of hospitalization was lower than that before (0(1) times, 0(0) times)( Z=-4.43, P<0.01), and the hospitalization days was lower than before (43(83.3) days, 0(0) days)( Z=-8.65, P<0.01) for the schizophrenic patients.The total BPRS score for schizophrenic patients decreased from (45.3±9.2) to (27.5±9.0) after 1 year of treatment( χ2=465.20, P<0.01), and the external aggressive behavior score was lower than the baseline score (1(7), 0(0))( F=308.36, P<0.01). The total effective rates were 30.5%(73/239), 77.4%(185/239) and 81.6%(195/239) after 8 weeks, 6 months and 1 year of treatment, respectively.The impairment in the four aspects of personal and social functioning were improved to varying degrees (all P<0.01). The severity of the disease was reduced 1 year after treatment.And the proportions of partial to very severe, moderate, none or mild were 10.0%(24/239), 56.5%(135/239), and 33.5%(80/239). Ordinal logistic regression analysis showed that younger age at treatment ( β=-0.08, OR=0.93, 95% CI=0.87-0.99) and older age at first onset ( β=0.07, OR=1.07, 95% CI=1.01-1.14) were associated with better treatment outcomes. Conclusion:Long-term injection of paliperidone palmitate can effectively improve the mental symptoms and individual social function of community patients with schizophrenia.

Association of intraperitoneal pressure and clinical symptoms in peritoneal dialysis patients / 中华肾脏病杂志

Objective:To explore the association between the intraperitoneal pressure (IPP) and clinical symptoms in peritoneal dialysis (PD) patients.Methods:It was a cross-sectional study. PD patients of Peking University First Hospital from January 1, to October 31, 2021, were enrolled according to the inclusion and exclusion criterion. The gold standard—Durand method was used to measure the IPP of PD patients for 2 L intraperitoneal volume, and clinical and laboratory data were collected. According to whether the IPP ≥ 18 cmH 2O or not, the participants were divided into elevated IPP group and normal IPP group. A self-designed semi-quantitative questionnaire was used to investigate the frequency and degree of five clinical symptoms, including abdominal distension, bloating, acid reflux, hiccup and chest tightness or suffrage, as well as the degree of symptom relief after emptying peritoneal dialysate. Pearson or Spearman correlation analysis was used to analyze the correlation between each variable and intraperitoneal pressure. Results:A total of 194 PD patients were enrolled, with age of (51.6±12.9) years old. Of them, there were 123 males (63.4%), 71 females (36.6%) and 60 patients (30.9%) with diabetes. The median dialysis vintage was 24.0 (10.0, 54.0) months. The IPP was (16.2±4.3) cmH 2O, and 70 (36.1%) patients had elevated IPP. Correlation analysis results showed that IPP was positively correlated with body weight ( r=0.23, P<0.001), body mass index ( r=0.41, P<0.001), body surface area ( r=0.15, P=0.030), triglyceride ( r=0.22, P=0.001), high-sensitivity C-reactive protein ( r=0.20, P<0.001), and negatively correlated with diabetes ( r=-0.14, P=0.034) and serum calcium ( r=-0.15, P=0.034). There was no significant correlation between IPP and the total frequency score of five clinical symptoms ( r=0.122, P=0.092). The frequency of stomach distension in elevated IPP group was significantly higher than that in normal IPP group ( P=0.002), and there were no significant differences in the degree and relief degree of stomach distension between the two groups (all P>0.05). There were no statistically significant differences in the extent, frequency and degree of relief of other four clinical symptoms between the two groups (all P>0.05). Conclusion:The increased IPP has little correlation with clinical symptoms, suggesting that it may be unreliable to adjust the infusion volume only by the subjective feeling of patients. It is necessary to monitor IPP as an objective variable.

Animal Model Analysis of Viral Myocarditis Based on the Clinical Characteristics of Traditional Chinese and Western Medicine / 世界科学技术-中医药现代化

Objective Viral myocarditis(VMC)is an inflammatory cardiovascular disease caused by Coxsackievirus,glandular virus,orphan virus and other viral infections.However,the pathogenesis of VMC is still unclear,so itis important to replicate a new animal model to study its mechanism.Methods So FAR,THE domestic and foreign literatures related to animal models of viral myocarditis were reviewed,and the modeling methods,types of animals,modeling mechanism,advantages and disadvantages,and clinical anastomosis of the included animal models were summarized and evaluated according to the characteristics of clinical symptoms of Chinese and western medicine.Results According to the statistics of the included models,it was found that the animal model of VMC induced by CVB3 was the most common.The model replication of viral myocarditis was mainly based on western medicine indicators,and the coincidence with traditional Chinese medicine syndrome type was low.In addition,there is no recognized model replication method with TCM syndrome types,and the model making process lacks TCM syndrome differentiation thinking,so it will cause certain limitations to the research of TCM.Conclusion Therefore,this article puts forward the improved method of animal model of viral myocarditis,and perfect the evaluation for animal model system,make the animal model of viral myocarditis build closer to clinical,for viral myocarditis curative effect of traditional Chinese medicines to judge and the discussion of pharmacological effects,provides a theoretical basis for the follow-up study of viral myocarditis provide theoretical basis for the prevention and control measures,the pathogenesis,in order to establish a combination model of viral myocarditis highly consistent with the clinical characteristics of traditional Chinese and Western medicine,so as to standardize the evaluation criteria of animal models of VMC,is the focus of future research on animal models of viral myocarditis.

A single-center retrospective analysis of severe acute respiratory syndrome coronavirus 2 infection in maintenance hemodialysis patients / 中华肾脏病杂志

Objective:To investigate the clinical characteristics and vaccination of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in maintenance hemodialysis (MHD) patients.Methods:It was a cross-sectional survey. Through wechat questionnaire star mode, the status of SARS-CoV-2 infection, clinical manifestation after infection and vaccination of MHD patients in Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine between December 8, 2022 and January 12, 2023 were retrospectively collected during the period that SARS-CoV-2 infection was managed with measures against class B infectious diseases. The patients were grouped according to whether they were infected with SARS-CoV-2 and whether they were complicated with pneumonia after infection during the study period. Logistic regression analysis was used to analyze the risk factors of SARS-CoV-2 infection combined with pneumonia or persistent symptoms after SARS-CoV-2 turning negative.Results:A total of 241 questionnaires were issued, and 223 valid questionnaires were returned, of which 175 patients (78.5%) were infected with SARS-CoV-2 during the study period. The time of negative conversion of antigen or nucleic acid after SARS-CoV-2 infection was 10 (7,14) days. Asymptomatic infections accounted for 10.3% (18/175). Symptomatic infections accounted for 89.7% (157/175), and the top five most frequent symptoms were cough (70.1%, 110/157), fever (64.3%, 101/157), pharyngeal pain (35.0%, 55/157), muscle pain (28.7%, 45/157), and nasal obstruction (21.0%, 33/157). Pneumonia was reported in 54.3% (95/175) of infected patients. There were no statistically significant differences in age, gender distribution, proportion of diabetes mellitus, and proportion of history of tumors between SARS-CoV-2-infected and uninfected patients (all P>0.05). Compared with the non-pneumonia group, the proportions of dyspnea (12.6% vs. 1.3%, χ2=8.181, P=0.004) and chest tightness (23.2% vs. 10.0%, χ2=5.293, P=0.021) in the pneumonia group were both higher. There were no significant differences in age, gender distribution, time of negative SARS-CoV-2 transition, number of symptoms and SARS-CoV-2 vaccination rate,and proportions of diabetes mellitus and tumors between the pneumonia group and the non-pneumonia group (all P>0.05). There were 48.6% (85/175) infected patients having long-lasting clinical symptoms after SARS-CoV-2 turning negative. Logistic regression analysis results showed that diarrhea was an independent influencing factor of pneumonia in MHD patients infected with SARS-CoV-2 [ OR (95% CI)=6.323 (1.061-37.682), P=0.043]. The number of symptoms at onset [ OR (95% CI)=1.571 (1.318-1.873), P<0.001] and history of tumors [ OR (95% CI)=0.206 (0.054-0.777), P=0.020] were independent influencing factors of long-lasting clinical symptoms. The SARS-CoV-2 vaccination rate was 7.2% (16/223) in MHD patients due to safety concerns (81.2%, 164/202). Conclusions:MHD patients are SARS-CoV-2-susceptible population. The clinical symptoms after infection are diverse, heterogeneous, and the proportion of complicated pneumonia is high. Diarrhea is an independent influencing factor of pneumonia in SARS-CoV-2-infected MHD patients. Nearly half of patients experience long-lasting clinical symptoms after SARS-CoV-2 turning negative. The low rate of vaccination in the MHD population necessitates increased awareness about the safety and efficacy of SARS-CoV-2 vaccine.

Advances in clinical research on drug-induced acute interstitial nephritis / 中国临床药理学与治疗学

The kidneys are one of the main excretory organs for drugs and when drugs are not excreted effectively, they can accumulate in the kidneys or in the interstitial tubules, leading to drug-induced kidney injury. The tubulointerstitium accounts for 80% of the volume of the kidney and is the primary site of response to various types of renal injury. This article focuses on drug-induced acute interstitial nephritis, highlighting its clinical symptoms, listing common induction drugs, analysing pathological features, and explaining its pathogenesis from the perspective of immune response, with the aim of providing a basic and clinical evidence for subsequent studies.

Correlation between abnormal sensory characteristics and clinical symptoms in children with autism spectrum disorders / 中华行为医学与脑科学杂志

Objective:To understand the sensory characteristics of children with autism spectrum disorder (ASD), and to explore its relationship with the clinical symptoms and to provide a reference basis for early diagnosis and intervention treatment of ASD.Methods:A cross-sectional survey was conducted to collect 216 children diagnosed with ASD according to DSM-5 from September 2021 to December 2021.All children were investigated with short sensory profile (SSP), autism behavior checklist (ABC) and social response scale (SRS). SPSS 21.0 was used for statistical analysis and the correlation between sensory characteristics and clinical symptoms of ASD children was analyzed by Pearson correlation.Results:The results showed that 120 of 216 with ASD children had abnormal SSP total score, with an abnormal rate of 55.6%.Among the seven dimensions, the abnormal rate of auditory filtering was the highest, reaching 83.8%, followed by low strength/weakness(60.2%), motor sensitivity(43.5%), low response/sensation seeking(39.8%), taste/smell sensitivity(37.5%), vision / hearing sensitivity(27.8%) and tactile sensitivity(17.6%), and the total incidence of paresthesia was 92.1%.There were significant differences in the total score of ABC and the five dimensions of sensation, communication, body movement, language and life self-care of ASD children with different sensory characteristics ( F=39.15, 39.99, 46.02, 29.18, 50.98, 51.76 respectively, all P<0.01). There were significant differences in the total score of SRS and social perception, social cognition, social communication, social motivation among ASD children with different sensory characteristics ( F=19.33, 29.47, 24.82, 29.68, 31.48, 39.86 respectively, all P<0.01). With the aggravation of sensory abnormalities, the total scores of ABC and SRS and the scores of each dimension increased.The total score of SSP was negatively correlated with the scores of sensation, communication, body movement, language, self-care and the total score of ABC ( r=-0.613, -0.631, -0.643, -0.558, -0.657, -0.679 respectively, all P<0.01). The total score of SSP was negatively correlated with social perception, social cognition, social communication, social motivation, autism behavior and the total score of SRS ( r=-0.440, -0.527, -0.504, -0.522, -0.542, -0.595 respectively, all P<0.01). Conclusion:Sensory abnormalities are common in ASD children, and with the aggravation of sensory abnormalities, the core symptoms and behavioral performance of ASD children are more obvious and positively correlated.

Effects of step-by-step fusion sandplay therapy on clinical symptoms, emotional cognition and quality of life in children with autism spectrum disorder / 中华行为医学与脑科学杂志

Objective:To explore the effect of step-by-step fusion sandplay therapy on clinical symptoms, emotional cognition and quality of life in children with autism spectrum disorder(ASD).Methods:Eighty children with ASD who were admitted in Zhumadian Central Hospital and the Third Affiliated Hospital of Zhengzhou University from January 2019 to January 2021 were selected as the research objects, and they were divided into the study group( n=45) and the control group ( n=35) according to the random number table method.The children in control group were given structured education combined with auditory system training intervention, while the children in study group were given step-by-step fusion sandplay therapy combined with pretend play training on the basis of the control group.Children in the two groups were intervened for 6 months.Autism behavior checklist (ABC), childhood autism rating scale (CARS), social responsiveness scale (SRS), emotion recognition tools and pediatric quality of life (PedsQL) were applied before and after 6 months of intervention.The scores of ABC, SRS, CARS, emotion recognition and PedsQL were compared between the two groups, and Pearson correlation analysis was used to analyze the relationships between the scores of ABC, SRS, CARS, emotion cognition and PedsQL.

Animal Models of Gastric Ulcer Based on Characteristics of Clinical Symptoms in Traditional Chinese and Western Medicine：A Review / 中国实验方剂学杂志

In recent years， with the changes of people's life rhythm and living environment， the incidence of gastric ulcer has shown an increasing trend year by year， and the affected population has become younger and younger. In order to further explore the pathogenesis of gastric ulcer and its diagnosis and treatment methods， a variety of animal models of gastric ulcer have been established clinically， such as stress type， chemical factor type， pyloric ligation type， helicobacter infection type and disease-syndrome combination type. The authors intend to summarize the modeling methods and advantages and disadvantages of existing models on the basis of reviewing the etiology， pathogenesis and diagnostic criteria of gastric ulcers. It was found that the non-injurious stress method （restraint stress， restraint immersion stress and restraint freezing stress， etc.）+traditional Chinese medicine （TCM） syndrome modeling， acetic acid gavage method+TCM syndrome modeling were ideal choices for replicating animal models of acute and chronic gastric ulcer. At the same time， the analysis of the coincidence degree between each gastric ulcer model and the clinical disease characteristics of Chinese and western medicine showed that the coincidence degree of western medicine diagnostic criteria was higher than that of TCM diagnostic criteria. The successful judgment of the model was also based on western medicine diagnosis. In short， the model is insufficient in depth and breadth. It only detects a few core indicators and main indicators， ignoring the impact of secondary indicators on the diagnosis of the disease. There is also a big gap between the disease-syndrome combination model and the TCM clinical syndromes of this disease. Therefore， the depth and width of the model evaluation criteria should be strengthened， and the evaluation system of the disease-symptom combination model should be improved， in order to provide a more accurate reference for the replication of gastric ulcer models， and to replicate animal models of gastric ulcer with high coincidence degree of Chinese and western medicine for research purposes.

Distribution of tick-borne diseases at Bulgan province, Mongolia / Монголын Анагаах Ухаан

Background@#Tick-borne encephalitis is human viral infection involving the nervous system and transmitted by the bite of infected tick. The TBE Virus is distributed in different geographical areas by three widespread subtypes of the virus: The Far East, Europe, and Siberia. The Far East type has a mortality rate was 30-35%, the European type has a mortality rate of 2.2%, and the Siberian type has a mortality rate of 6-8% (A.G. Pletnev, 1998) [2]. </br>In recent years, human cases of tick-borne infections have been reported in 19 European countries and four Asian countries (Mongolia, China, Japan, and South Korea) [3]. </br>Human cases of tick-borne encephalitis, tick-borne rickettsiosis, and tick-borne borreliosis have been registered in Mongolia since 2005. Deaths have been reported year by year [5]. </br>During 2005 to 2021, tick-borne rickettsiosis (71.6%), tick-borne encephalitis (17.3%) and tick-borne borreliosis (52.9%) were confirmed by epidemiological, clinical and laboratory tests at the NCZD. </br>Tick-borne encephalitis was registered in 63 soums of 15 provinces and 9 districts of the capital city, of which 90% were infected with tick bites in Selenge and Bulgan provinces. The average mortality rate is 4.9% (14), of which 28.6% in Bulgan province and 2.7% in Selenge province. </br>Tick-borne encephalitis is the leading cause of death in Bugat soum of Bulgan province and more infected men about 40 years of age [7]. @*Purpose @#Collect ticks from selected soums of the provinces, identify tick species, species composition, distribution, tick densities, pathogens of tick-borne diseases, conduct population surveys to assess the risk of tick-borne infections, and identify tick-borne infections.@*Material and Method@#Ticks were collected by flag from birch trees in birch forests and meadows with biotope and overgrown berries, determined morphological analyze and molecular biological investigation for detecting tickborne pathogens. </br>Questionnaires were collected from selected soum residents according to a specially designed randomized epidemiological and clinical survey card, collected information and forms were submitted to soum hospitals with a history of tick bites (according to clinical criteria). Serological tests were performed to detect IgG-specific antibodies to the collected serum mites.@*Result and conclusion@#Collected 121 ticks (120 I. persulcatus and 1 D. nuttalli) and not wound egg, larvae, nymphs. By molecular biological investigation detected 3.5% of I.persulcatus from Khutag-Undur soum of Bulgan province, 3.5% of anaplasmosis, and 14.1% of I.persulcatus mites from Bugat soum. 1.5% borreliosis, 3.1% anaplasmosis. </br>Detected DNA of 100% tick-borne rickettsiosis from D.nutalli ticks and determined circulation of infection among tick in Bugat and Khutag-Undur soums of Bulgan province. </br>247 people were surveyed, 56 blood serum from cases. Detected Q fever, erysipelas, and anaplasmosis, tick-borne borreliosis 3 (5.4%), tick-borne rickettsiosis 26 (46.4%), Japanese encephalitis 3 (5.4%), tick-borne encephalitis tick-borne rickettsiosis 6 (13.0%), tick-borne rickettsiosis tick-borne borreliosis 1 (1.8%), tick’s rickettsiosis Japanese encephalitis 1 (1.8%), tick-borne encephalitis tick-borne borreliosis 1 (1.8%). </br>By investigation, vaccination (88%) and wearing long-sleeved shirts and pants (81%) were the most effective ways to prevent tick bites (81%) [15]. According to our research, the percent of population knowledge in Bulgan province was insufficient (40.9%) which there is a lack of information, training and advertisement among the population in the province.

A Study on Different Diagnostic Approach for Early Recognition of Canine Pyometra

The study aimed to evaluate ultrasonographic findings, radiography, and blood profile in 24 bitches presented for treatment of pyometra. Clinical symptoms such as anorexia, vaginal discharge, depression, polyuria/polydipsia, vomiting, and abdominal distension were seen. Among these various types of diagnostic approaches, ultrasonography a powerful tool for the early detection of uterine abnormalities. Before any clinical alterations could be noticed, ultrasonography allowed the diagnosis of pathologic abnormalities. Pyometra must be identified, diagnosed, and treated as soon as possible to achieve a successful outcome

Animal model analysis of rheumatoid arthritis based on clinical characteristics of Chinese and Western medicine / 中国中药杂志

Rheumatoid arthritis(RA) is an autoimmune disease involving multiple joints bilaterally with symmetrical polyarthritis as the main symptom. The high disability rate of this disease seriously affects the quality of life of patients and even threatens their lives. The establishment of a good animal model is of great significance for the diagnosis and clinical prevention of RA. Based on the clinical characteristics of RA in traditional Chinese and Western medicine, the common animal models of RA were summarized, including drug-induced, gene-related, and syndrome and disease combined models. Joint swelling, pain, redness, nodules, and joint deformity are the main criteria for model evaluation, which have certain differences from the clinical diagnostic criteria of RA. From the perspective of syndrome differentiation, the animal model combining syndrome and disease only simulates the syndrome of traditional Chinese medicine and has no direct causal relationship with the formation of RA. In this paper, we analyzed the advantages and disadvantages of animal models of RA and the coincidence degree of the models with the clinical characteristics and then put forward the corresponding recommendations for the evaluation and improvement of these models, aiming to make the animal models of RA closer to the clinical symptoms and play an important role in the clinical diagnosis and treatment of RA.

Analysis of animal models of hypertension based on characteristics of clinical symptoms of Chinese and western medicine / 中国中药杂志

Hypertension, a cardiovascular disease with main clinical manifestations of dizziness and elevated blood pressure, especially elevated arterial pressure, features high prevalence rate and low control rate, which affects patients' quality of life. Therefore, establishing a good animal model of hypertension is of great significance for its diagnosis and clinical prevention and treatment. Based on the clinical characteristics of hypertension in traditional Chinese and western medicine, this study summarized the advantages and disadvantages of current hypertension animal models: gene-related model, surgery-caused model, drug-induced model, and environment-induced model, and investigated the similarity to the clinical symptoms in traditional Chinese medicine and Western medicine. Among them, spontaneously hypertensive rats, models established with the surgical two-kidney one-clip, one-kidney one-clip, two-kidney two-clip, and abdominal aorta constriction methods, models induced with the drug deoxycorticosterone acetate, and models induced with the high-fat high-purine diet showed symptoms highly similar to the clinical manifestations. Then, the corresponding evaluation and improvement methods of hypertension animal models were proposed. This study provides suggestions for the establishment of hypertension animal model so that the symptoms are more similar to the clinical characteristics of hypertension in traditional Chinese and Western medicine, which is important for the clinical diagnosis and treatment of hypertension.

Analysis of animal models of ulcerative colitis based on characteristics of clinical symptoms of traditional Chinese and Wes-tern medicine / 中国中药杂志

This article aims to provide a good experimental method for the study of drug treatment of ulcerative colitis. According to the characteristics of ulcerative colitis's clinical symptoms, common ulcerative colitis animal models were analyzed. Based on the characteristics of clinical symptoms of traditional Chinese medicine and Western medicine for ulcerative colitis disease, the existing commonly used animal models of ulcerative colitis were analyzed to summarize the current matching degree, advantages and disadvantages of the exi-sting animal models of ulcerative colitis and clinical symptoms. At present, studies on ulcerative colitis mainly adopt four types of induction modeling methods, such as immunization, chemical stimulation, compound method and gene model. There are many reported methods of colitis modeling, but no model can reflect the characteristics of clinical symptoms of ulcerative colitis treated with Western or Chinese medicine. This article summarizes the characteristics, clinically relevant symptoms and applicable scope of immunization, chemical stimulation, compound method, and gene model, so as to provide a reliable animal model for subsequent studies of prevention and treatment of colitis.

Animal model analysis of secretory otitis media based on characteristics of clinical symptoms of traditional Chinese and Western medicine / 中国中药杂志

Based on the characteristics of clinical symptoms of secretory otitis media in traditional Chinese and Western medicine,by reference to clinical diagnostic criteria,efforts were made to analyze and establish the Western medical diagnostic criteria and traditional Chinese medicine( TCM) syndrome differentiation criteria for secretory otitis media,and summarize the modeling methods and model characteristics of secretory otitis media animal models. According to the clinical diagnostic criteria and symptom characteristics,the coincidence degree between the existing animal models and clinical symptoms was evaluated,and its advantages and disadvantages were defined. On the basis of the statistical results,there were fewer methods for modeling secretory otitis media animal models,and only a specific relevant pathogenic mechanism could be revealed. Among them,the model with a higher coincidence degree was genetic engineering technology modeling and injection into the middle ear vesicles. The two modeling methods of bacterial factors highly coincided with the clinical symptoms of Western medicine,but both failed to reflect the TCM syndrome type. Therefore,establishing an animal model that simultaneously reflects the characteristics of clinical symptoms of secretory otitis media in traditional Chinese and Western medicine,and improving the evaluation criteria of secretory otitis media based on animal models are the main tasks of future studies on secretory otitis media.
