RESUMEN
ObjectiveTo observe the microbial changes in Wistar rats with liver injury caused by the Dictamni Cortex-Flavescens Sophora by high-throughput sequencing technology and investigate the potential mechanism of liver injury caused by the Dictamni Cortex-Flavescens Sophora. MethodFemale Wistar rats were randomly divided into four groups： normal group， as well as low-dose， medium-dose， and high-dose groups of traditional Chinese medicine （TCM）. The rats were gavaged with the Dictamni Cortex-Flavescens Sophora in different doses （4.125， 8.25， 16.5 g·kg-1 of raw drug respectively） for 28 days， and the general condition was recorded. The liver-body weight ratio was calculated， and the biochemical indexes of serum were observed. The Hematoxylin-eosin （HE） staining was used to observe pathological changes in the liver， and 16S rDNA high-throughput sequencing was utilized to detect fecal microbial changes in rats. ResultCompared with the normal group， Dictamni Cortex-Flavescens Sophora increased the liver weights and liver-body weight ratios of Wistar rats. The difference in liver weight between the medium-dose and high-dose groups of TCM was statistically significant （P<0.05）， and the liver-body weight ratios of the low-dose， medium-dose， and high-dose groups of TCM were all statistically significant （P<0.05）. Compared with the normal group， serum albumin and cholesterol levels increased in the medium-dose and high-dose groups of TCM （P<0.05）. The histopathology of the liver in the medium-dose and high-dose groups of TCM showed tiny vacuole-like changes. Compared with the normal group， there were obvious intestinal flora disorders after administration of Dictamni Cortex-Flavescens Sophora， and alpha diversity increased in the medium-dose and high-dose groups of TCM. The principal coordinates analysis showed that species increasingly deviated from the normal group as the administered dose increased. Compared with the normal group， the proportion of Firmicutes and Bacteroidota decreased after the drug administration， and the genus level of Parasutterella， Romboutsia， Turicibacter， Allobaculum， and Dubosiella increased. The genus level of Lachnospiraceae_NK4A136_group， Blautia， Erysipelatoclostridium， Muribaculum， and Ruminococcus_gnavus_group decreased. The correlation analysis showed that Parasutterella， Romboutsia， Turicibacter， Allobaculum， and Dubosiella were positively correlated with serum cholesterol and liver-body weight ratio， and lanchnospiraceae_NK4A136_group， Blautia， Muribaculum， Erysipelatoclostridium， and Ruminococcus_gnavus_group were negatively associated with serum cholesterol and liver-body weight ratio. ConclusionThe liver injury caused by Dictamni Cortex-Flavescens Sophora is manifested as a lipid metabolism disorder， and the mechanism is related to the increase in lipid metabolism-related microorganisms.
RESUMEN
Objective To investigate the distribution of traditional Chinese medicine(TCM)syndrome types in diabetic kidney disease(DKD),and to explore the correlation between TCM syndrome types and laboratory indices,so as to provide an objective basis for the TCM syndrome differentiation and treatment of DKD.Methods Syndrome differentiation was carried out in the 157 patients with DKD at stages Ⅲ and Ⅳ,and then the distribution of the syndromes of deficiency in the origin and the syndromes of excess in the superficiality was explored.The levels of 24-hour urinary total protein(24hUTP),serum creatinine(Scr),blood urea nitrogen(UREA),plasma albumin(Alb),total cholesterol(TC),and triglyceride(TG)of the patients were detected,and then the relationship between the TCM syndrome types and the biochemical indexes was analyzed.Results(1)The distribution of the syndromes of deficiency in the origin in DKD patients at different stages showed that DKD patients at stage Ⅲ were mainly differentiated as yin deficiency and dryness-heat syndrome[58.57％(41/70)],qi and yin deficiency syndrome[28.57％(20/70)],yin and yang deficiency syndrome[10.00％(7/70)],and spleen and kidney qi deficiency syndrome[2.86％(2/70)];DKD patients at stage Ⅳ were mainly differentiated as yin deficiency and dryness-heat syndrome[40.23％(35/87)],qi and yin deficiency syndrome[29.89％(29/87)],spleen and kidney qi deficiency syndrome[18.39％(16/87)],and yin and yang deficiency syndrome[11.49％(10/87)].The differences in the distribution of the syndromes of deficiency in the origin among the DKD patients at different stages were statistically significant(P<0.05).However,with the progression of the disease,DKD patients at different stages in general showed a trend of the decrease in the proportion of yin deficiency and dryness-heat syndrome while the increase in the proportions of qi and yin deficiency syndrome,spleen and kidney qi deficiency syndrome,and yin and yang deficiency syndrome.(2)The distribution of the syndromes of excess in the superficiality in DKD patients at different stages showed that DKD patients at stage Ⅲ were mainly differentiated as damp-heat syndrome[54.29％(38/70)],phlegm-stasis syndrome[27.14％(19/70)],blood-stasis syndrome[10.00％(7/70)],and cold-damp syndrome[8.57％(6/70)];DKD patients at stage Ⅳ were mainly differentiated as damp-heat syndrome[44.83％(39/87)],phlegm-stasis syndrome[35.63％(31/87)],cold-damp syndrome[14.94％(13/87)],and blood-stasis syndrome[4.60％(4/87)].There were no significant differences in the distribution of the syndromes of excess in the superficiality among the DKD patients at different stages(P>0.05).(3)The analysis of relationship between TCM syndrome type and biochemical indexes showed that Scr and UREA levels of DKD patients with spleen and kidney qi deficiency syndrome were significantly higher than those of patients with yin deficiency and dryness-heat syndrome,and the differences were statistically significant(P<0.05);Scr and 24hUTP levels of DKD patients with cold-damp syndrome were significantly higher than those of patients with damp-heat syndrome,and the differences were statistically significant(P<0.05).Conclusion DKD patients at stages Ⅲ and Ⅳ are all predominantly suffering from yin deficiency and dryness-heat syndrome,and with the progression of the disease,the syndrome of yin deficiency and dryness-heat develops into qi and yin deficiency syndrome,spleen and kidney qi deficiency syndrome,and yin and yang deficiency syndrome sequentially.Pathogenic dampness and blood stasis are the main pathogenic factors of DKD.And Scr,UREA,and 24hUTP are correlated with the TCM syndrome types of DKD,which will be helpful for the differentiation of TCM syndrome types of DKD.
RESUMEN
Objective To analyze the metabolomics characteristics of chronic atrophic gastritis(CAG)patients with liver-stomach qi stagnation and spleen-stomach weakness syndromes based on non-targeted metabolomics technology,and to identify the serum differentiated metabolites related to traditional Chinese medicine(TCM)syndrome of CAG patients,so as to provide a reference for the objectification of syndrome differentiation.Methods Sixty patients with CAG were included,including 30 cases of liver-stomach qi stagnation syndrome and 30 cases of spleen-stomach weakness syndrome.Fasting blood of 5 mL was collected from the cubital vein of patients in the two groups,and the serum levels of metabolites were detected by ultra-high-performance liquid chromatography-mass spectrometry(UPLC-MS)methods.The principal component analysis(PCA),orthogonal partial least squares-discriminant analysis(OPLS-DA),and cluster analysis were used to screen the differentiated metabolites of CAG patients with liver-stomach qi stagnation syndrome and spleen-stomach weakness syndrome.Finally,metabolite pathway analysis was performed for the obtained differentiated metabolites using the KEGG database.Results The results for the screening of differentiated metabolites showed that significant differences of amino acid derivatives and small peptide metabolites were presented between CAG patients with liver-stomach qi stagnation syndrome and CAG patients with spleen-stomach weakness syndrome.The amino acid derivatives consisted of N-acetylglycine,histamine,O-phosphoserine,selenomethylselenocysteine,and methyl-tyrosine.And the small peptide metabolites consisted of tyrosine-leucine-phenylalanine,histidine-alanine-glutamate-lysine,L-asparagine-L-proline-L-serine,and L-isoleucine-L-isoleucine.Conclusion Differences in amino acid metabolism exist between CAG patients with liver-stomach qi stagnation syndrome and those with spleen-stomach weakness syndrome,and metabolites such as N-acetylglycine,intermethyltyrosine,and O-phosphoserine may be the potential biomarkers for distinguishing liver-stomach qi stagnation syndrome from spleen-stomach weakness syndrome in CAG patients.

RESUMEN
Objective To investigate the distribution characteristics of traditional Chinese medicine(TCM)syndromes in girls with idiopathic central precocious puberty(ICPP)from Hainan province.Methods A total of 216 cases of ICPP girls admitted to Hainan Women and Children's Medical Centre from January 2019 to December 2021 were retrospectively collected.The frequency statistics and grading of TCM syndromes in the included ICPP girls were carried out,and the distribution characteristics of TCM syndromes were discussed on the basis of the analysis of the three TCM syndrome types of yin deficiency and fire exuberance syndrome,qi and blood insufficiency syndrome and incoordination between heart and kidney syndrome.Results(1)The age of ICPP onset in 216 girls were between 4 and 10 years old,with an average onset age of(7.15±1.06)years.The highest incidence rate of ICPP was found in the girls aged over 7 years old while less than 8 years old,which was 49.54%.(2)Of the three TCM syndrome types,yin deficiency and fire exuberance syndrome accounted for the highest proportion(147 cases,68.06%),followed by the qi and blood insufficiency syndrome(41 cases,18.98%)and the incoordination between heart and kidney syndrome(28 cases,12.96%).(3)The common 16 TCM symptoms(frequency＞25.0%)in descending order of frequency were aversion to heat and night sweating,feverish sensation in soles and palms,breast distension and pain,irritability,thready and rapid pulse,dry stools,dry throat and mouth,hot flushes,excessive intake of fat and sweet food,red tongue with less fur,depression,mental weakness,flushed cheeks,insomnia and dreaminess,red tongue with yellow fur,and bitterness and dryness in the mouth.(4)The distribution of the age in ICPP girls with various syndromes was as follows:yin deficiency and fire exuberance syndrome and qi and blood insufficiency syndrome were more common in the ICPP girls aged over 7 years old while less than 8 years old(accounting for 58.50%and 51.22%),and incoordination between heart and kidney syndrome was more common in ICPP girls aged over 8 years old while less than 9 years old(accounting for 89.29%).Conclusion Yin deficiency and fire exuberance syndrome is the common TCM syndrome that accounts for the highest proportion in ICPP girls from Hainan province.The study of the distribution of TCM syndromes in girls with precocious puberty will be helpful for the observation of the early clinical symptoms of precocious puberty and early diagnosis of the disease,and can provide clues and evidence for the clinical diagnosis and medication for girls with ICPP.
RESUMEN
Objective To study the traditional Chinese medicine(TCM)constitution characteristics of overweight/obese patients in Shanghai region and to investigate the correlation of TCM constitution with body composition.Methods Relevant data were collected from the patients with complete information of TCM constitution and human body composition analysis who visited the specialized outpatient clinic of acup-moxibustion catgut embedding therapy in the Department of Endocrinology,Shanghai Tenth People's Hospital from August 2020 to December 2022.The patients were divided into a normal body mass group(BMI＜24 kg/m2),an overweight group(24 kg/m2≤BMI＜28 kg/m2)and obesity group(BMI≥28 kg/m2),and then the distribution of TCM constitution types in the three groups of patients were analyzed.After that,the correlation between TCM constitution and body composition were explored with multiple regression analysis.Results(1)A total of 315 patients were included,of which 43 patients had normal body mass,85 patients were overweight and 187 patients were obese.(2)The TCM constitution types in descending order of the composition ratio in the normal body mass group and in the overweight group were spleen deficiency constitution,liver stagnation constitution,damp-heat constitution,yang deficiency constitution,and yin deficiency constitution,in the obese group were spleen deficiency constitution,yang deficiency constitution,damp-heat constitution,liver stagnation constitution,and yin deficiency constitution,and in the overweight/obese group were spleen deficiency constitution,damp-heat constitution,yang deficiency constitution,liver stagnation constitution,and yin deficiency constitution.No statistically significant differences of the distribution of TCM constitution types were shown between normal body bass population and overweight/obese population(P＞0.05).In both normal body mass population and overweight/obese population,the single body constitution type was common,and biased constitution was rare,and there was no statistically significant difference when comparing between the two groups(P＞0.05).(3)The results of multiple regression analysis showed that the basal metabolism of all patients was positively correlated with yang deficiency constitution and was negatively correlated with damp-heat constitution,and the differences were statistically significant(P＜0.01).It is indicated that if the score of yang deficiency constitution rose by one point,the basal metabolism would increase by 0.54 kcal,and if the score of damp-heat constitution decreased by one point,the basal metabolism would decrease by 1.005 kcal.Conclusion In Shanghai region,obesity may be the main indication of the variation of the body constitution.In addition to spleen deficiency constitution,the proportions of yang deficiency constitution,damp-heat constitution and liver stagnation constitution are also higher in obese patients.In terms of the correlation between TCM constitution and body composition,basal metabolism is positively correlated with yang deficiency constitution and is negatively correlated with damp-heat constitution.Therefore,for the patients with yang deficiency constitution and damp-heat constitution,the influence of the basal metabolism level on the development of the disease should be taken into account.
RESUMEN
Objective To study the correlation between traditional Chinese medicine(TCM)constitution and pathogenic factors in patients with ankylosing spondylitis(AS).Methods One hundred patients of AS and their family members who had medical consultation in the Fifth Hospital of Xi'an(i.e.,Shaanxi Hospital of Integrated Traditional Chinese and Western Medicine)in August 2019 and September 2020 were selected as the study subjects.The guidelines of Classification and Determination of Traditional Chinese Medicine Constitution issued by the China Association of Chinese Medicine were adopted to determine the traditional Chinese medicine(TCM)constitution types of the study subjects.The sociodemographic information,living habits,clinical symptoms,and TCM constitution types of the AS patients and their family members were collected by means of questionnaires and clinical investigations,and then the pathogenic factors of the patients with AS were investigated.The binomial Logistic regression model was used to analyze the correlation between TCM constitution types and pathogenic factors in patients with AS.Results(1)Among the 100 AS patients,the majority of them had the biased constitutions,and the biased constitutions with the occurrence frequency in descending order were yang deficiency constitution,qi deficiency constitution,and damp-heat constitution,which accounted for 33.00%,14.00%,and 18.00%,respectively.(2)The prevalence rates of AS in the first-,second-,and third-degree relatives of AS patients were 56.25%,40.00%and 25.00%,respectively.For the positive rates of human leukocyte antigen B27(HLA-B27)in AS patients and their family members,HLA-B27 in AS patients was all positive,while the positive rates of HLA-B27 in the first-,second-,and third-degree relatives of AS patients were 44.31%,30.67%and 15.63%,respectively.(3)The results of regression analysis showed that the disease duration of AS patients was significantly correlated with qi deficiency constitution,the grading of sacroiliac arthritis was correlated with qi stagnation constitution,and age was correlated with blood stasis constitution(P＜0.05 or P＜0.01).The results indicated that disease duration and age were the important factors affecting the constitution types of AS patients,and disease duration was closely related to qi deficiency while age was closely related to blood stasis.Conclusion AS is a highly hereditary autoimmune disease,and its onset is associated with HLA-B27.Yang deficiency is the basic constitution type of AS,and damp-heat constitution is the main constitution type in the progression of AS(especially in the active stage of the disease).The prolongation of the disease will exacerbate the illness condition of AS and then the manifestations of qi deficiency will be more obvious.
RESUMEN
Objective To explore the feasibility and operability in identifying the therapeutic dominant stages of traditional Chinese medicine(TCM)based on subdivision model of disease course.Methods The hierarchical Bayesian model was used to differentiate the disease course of 125 cases of premature ovarian failure(POF),and the disease course of POF were divided into the occult stage,diminished ovarian reserve(DOR)stage,premature ovarian insufficiency(POI)stage,and POF stage.An then the paired sample t-test,Pearson correlation analysis and expert in-depth interview were used for the analysis of the therapeutic effects of TCM for POF at various stages.Results(1)Compared with POF stage,DOR and POI stages were frequently intervened by Chinese patent medicine.(2)In DOR(complicated with POI)stage and POF stage,there was significant difference between the degree of TCM intervention and the therapeutic effect(t =-3.70,P＜0.001).(3)The degree of TCM intervention was positively correlated with treatment outcomes in the DOR stage(r = 0.679,P＜0.001),so did in the POF stage(r = 0.432,P＜0.001),but the correlation in the POF stage was slightly lower than that in the DOR stage.(4)The results of in-depth interviews with experts of TCM gynecology showed that in the concealed phase of POF,the prognosis would be most favorable if TCM regulation and intervention were performed.In the DOR stage and POI stage,treatment with Chinese medicine prescriptions usually brought about better curative effect and prognosis.For the patients at POF stage,the therapeutic effect of TCM depended on the patients'compliance and the treatment course,and the effect was relatively not as good as that of the previous stages.Conclusion In the DOR stage and POF stage,the higher the degree of TCM intervention,the better the prognosis will be achieved for the patients treated with western medicine.In the POF stage,the efficacy of TCM intervention is reduced to a certain extent compared with the DOR stage.The results indicated that it is feasible and operable to identify the TCM therapeutic dominant stages based on the subdivision model of disease course.
RESUMEN
Objective To evaluate the clinical efficacy of Chevron minimally-invasive osteotomy and internal fixation with ISO intramedullary plate plus traditional Chinese medicine(TCM)bone-setting manipulations for the treatment of moderate hallux valgus.Methods A retrospective study was conducted.A total of 49 patients(62 feet)with moderate hallux valgus were treated with Chevron minimally-invasive osteotomy and internal fixation with ISO intramedullary plate,and were given TCM bone-setting manipulations before the operation,during the operation,and after the operation.The efficacy was evaluated by using the Visual Analogue Scale(VAS)score and the American Orthopedic Foot and Ankle Society(AOFAS)forefoot score after the operation.Before the operation and 12 months after the operation,the hallux valgus angle(HVA),intermetatarsal angle(IMA)between the first and second metatarsal bone,and the distal metatarsal articular angle(DMAA)showed by X-ray imaging in the weight-bearing position of the foot were recorded.Results(1)All of the 49 patients were followed up for 12 to 24 months,with a mean of(20.6±3.1)months.(2)The X-ray imaging assessment showed that 12 months after the operation,the mean HVA,IMA and DMAA values of the 49 patients(62 feet)were significantly lower than those before the operation,and the differences were all statistically significant(P＜0.01).(3)Twelve months after the operation,the pain VAS score of 49 patients was(3.14±1.21)points,which was significantly lower than the preoperative score points(7.26±2.52),and the difference was statistically significant(P＜0.01).(4)The assessment of joint function showed that 12 months after the operation,the scores of various AOFAS items of pain,function and hallux alignment as well as the overall AOFAS scores of 49 patients were significantly higher than those before the operation,and the differences were statistically significant(P＜0.01).(5)For the 62 feet in 49 patients,the excellent efficacy was achieved in 53 feet,good efficacy was achieved in 7 feet,and fair efficacy was achieved in 2 feet,with the fine rate of 96.77%(60/62).Conclusion For the treatment of moderate hallux valgus,the application of Chevron minimally-invasive osteotomy and internal fixation with ISO intramedullary plate plus TCM bone-setting manipulations is effective on promoting the reset of hallux-metatarsophalangeal joint,restoring the balance of the joint,and maintaining the equilibrium state of the joint through postoperative rehabilitation guidance.The combined therapy exerts certain efficacy,reduces the recurrence rate,and eventually achieves the early rehabilitation after the operation.
RESUMEN
Objective:To construct the impact factor model of primary traditional Chinese medicine (TCM) health management service quality, and put forward corresponding policy suggestions.Methods:In this cross-sectional study, the typical sampling and random sampling method were used to select 39 insiders of primary TCM health management service from 15 communities in Zhejiang Province from August to October in 2022. Interviews on service projects, implementation effects and impact factors were conducted, the three-level coding of interview record was carried out using the grounded theory research method, a model of impact factor for health management service quality of basic TCM was constructed, and the corresponding policy recommendations were put forward.Results:Based on the open coding of 39 original interview data, a total of 516 reference points were obtained, and 53 initial concepts related to the topic were formed and summarized into 17 first-level categories. Through the summary of main axis coding, 6 main categories of “policy environment”，“health literacy”，“community orientation”，“capacity building”，“health preference” and “conflict of interest” were extracted. The logical correlation between the six main categories were analyzed with selective coding, an impact factor model was constructed in accordance with the story line of factors affecting service quality. The story line of this model was as follows: first, the policy environment was the external guarantee of community TCM service quality; second, as the demand-side of the services, the health literacy and requirement of residents was the regulatory factor for service quality; in addition, the community played the role of the supply-side of the services, the service ability construction was the key factor, and the community functions and target orientation was the internal driving factor, meanwhile, the internal/external conflicts of interest had a negative constraint on the service quality.Conclusions:The guarantee intensity of external policy environment is limited, the service demand side pays insufficient attention, and the service supply side functions are absent at the present stage. It is necessary to improve the external policy environment, deepen the connection between supply and demand sides in the field of TCM health service, promote the capacity building of TCM service at the grass-roots level, balance the interests of relevant departments of TCM service, in order to improve the quality of TCM health management service at the grass-roots level.
RESUMEN
Tumor metastasis is the major cause of death for tumor patients and the key bottleneck of clinical treatment. In recent years， basic and clinical studies have recognized that tumor microenvironment （TME） is highly correlated with tumor metastasis， which provides hope for anti-metastatic drug development and clinical treatment. At present， the mainstream studies on TME represented by immune checkpoint inhibitors （ICIs） mainly focus on the rectification of immune function of T cells and B cells. However， a large number of studies have shown that the significance of other members of TME for tumor metastasis cannot be ignored， which greatly reflects the progress of anti-metastatic research based on TME regulation. This review focused on tumor metastasis， summarized the mechanism of action of non-T and non-B immune cells ［tumor-associated macrophages （TAMs） and tumor-associated neutrophils （TANs）］ and non-immune members ［vascular endothelial cells （ECs）， tumor-associated fibroblasts （CAFs）， and blood platelet］ in the process of tumor metastasis in TME based on the literature over the recent five years， and explored their key value in the treatment of metastasis. At the treatment level， this review focused on the perspective of the integration of frontier and traditional methods and took the functional homeostasis remodeling of TME as the entry point to summarize the activity and mechanism of traditional Chinese medicine （TCM） regulation of non-T and non-B immune cells and non-immune members and highlight its advantages and characteristics in clinical intervention of metastasis. This review helps to break through the limitations of over-reliance on T and B immune cells in anti-metastatic research， make the research rely on a wider range of cell groups， explore the potential value of TME in anti-metastatic drug intervention， and enrich the idea and strategy of understanding the anti-metastatic pharmacological activity. The review is also expected to provide a broader vision for the research and development of new anti-metastatic drugs.

The time span for the paper retrieval was set from the foundation of the databases to October 1, 2023. Statistical analyses were performed using Stata 12 and Python (V 3.9). The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement was used to assess the reporting quality of included studies.@*Result@#Overall, 1 356 articles were selected, and 40 cross-sectional studies were included with 10 270 participants. The most common TCM patterns before, one to two weeks after, and six months to one year after PCI was Qi stagnation and blood stasis (n = 261, 36.45%), intertwined phlegm and blood stasis (n = 109, 27.18%), and Qi deficiency and blood stasis (n = 645, 37.03%), respectively. Smoking [odds ratio (OR) = 1.15, 95% confidence interval (CI) (0.83 – 1.47), I 2 = 24.7%, P = 0.257], pattern of congealing cold and Qi stagnation [OR = 4.62, 95% CI (1.37 – 7.86), I 2 = 61.6%, P = 0.074], and low-density lipoprotein (LDL) [OR = 1.38, 95% CI (0.92 – 1.85), I 2 = 12.2%, P = 0.286] were risk factors for restenosis. Hypertension [OR = 7.26, 95% CI (3.54 – 14.88), I 2 = 91.6%, P = 0.001], and overweight [i.e., body mass index (BMI) > 23] [OR = 1.20, 95% CI (1.07 – 1.35), I 2 = 85.3%, P = 0.009] were significant risk factors of concomitant anxiety.@*Conclusion@#This systematic review andet a-analysis revealed that patients with different TCM pattern types have distinct characteristics and risk factors after PCI. More high-qualitystudies are warranted to provide supportive evidence for future research and clinical practice.
RESUMEN
Objective @#To investigate the effects of Tuina targeting different body parts on the behaviors and gut microflora of rat models with valproic acid (VPA)-induced autistic spectrum disorder(ASD).@*Methods@#Twenty female Sprague Dawley (SD) rats with 12.5 d of pregnancy were randomly divided into VPA model group [intraperitoneal injection of VPA (600 mg/kg), n = 15] and saline group (intraperitoneal injection of equal amount of normal saline, n = 5). The offspring male rats injected with saline were secleted as control group. The offspring male rats injected with VPA were randomly divided into VPA, dorsal, and abdominal groups (n = 7 in each group). On the 21st day after birth, three-chamber social test, open field test, and marbleburying test were carried out to observe the social abilities, anxiety behaviors, and stereotypical behaviors of rats in the four groups. Rats in dorsal and abdominal groups underwent Tuina for 14 d, twice a day. On the 35th day, behavioral tests were conducted again, and intestinal contents were taken for species composition and structural analysis, as well as marker and differential species analysis.@*Result@#(i) According to behavioral observations, compared with VPA group, the social and movement time in the central open field of rats in dorsal group increased significantly (P <0.05), and the number of buried marbles decreased markedly (P < 0.01), indicating improvement on their social abilities, anxiety behaviors, and stereotypical behaviors as consequences of dorsal Tuina; and the number of buried marbles was reduced as well in abdominal group when compared with VPA group (P < 0.05), suggesting the improvement on their stereotypical behaviors following abdominal Tuina. In the marble-burying test, the number of marbles buried in dorsal group was less than in abdominal group, and the stereotypical behaviors were improved more significantly (P < 0.05), and there were no significant differences in the three-chamber social and open field tests between the two groups (P >0.05). (ii) In accordance with intestinal microflora detection results, compared with VPA group, both dorsal and abdominal groups showed increased richness (P < 0.05) and elevated diversity (P < 0.05 in dorsal group and P < 0.01 in abdominal group) in intestinal microflora. The results of differential analysis indicated that at the phylum level, compared with VPA group, the relative abundance of Firmicutes in rats in abdominal group showed a significant reduction trend (P < 0.05); at the genus level, compared with VPA group, the relative abundance of Lactobacillus in rats in dorsal and abdominal groups decreased significantly (P < 0.05). Dorsal group also showed significant increase in the genus Blautia in the analysis of marker species comparedwith VPA group (P < 0.05).@*Conclusion@#Tuina impacted the behavior and gut microflora structure of ASD model rats. Dorsal intervention had a significant effect on social abilities, anxiety behaviors, and stereotypical behaviors of ASD model rats, while abdominal intervention only had an obvious effect on stereotypical behaviors. Both dorsal and abdominal interventions increased the richness and diversity of gut microflora of ASD model rats, with abdominal intervention improving the intestinal microbial diversity more significantly and resulting in a more uniform species distribution.
RESUMEN
Objective @#To construct a traditional Chinese medicine (TCM) knowledge base using knowledge graph based on deep learning methods, and to explore the application of joint models in intelligent question answering systems for TCM.@*Methods@#Textbooks Prescriptions of Chinese Materia Medica and Chinese Materia Medica were applied to construct a comprehensive knowledge graph serving as the foundation for the intelligent question answering system. In the study, a BERT+Slot-Gated (BSG) deep learning model was applied for the identification of TCM entities and question intentions presented by users in their questions. Answers retrieved from the knowledge graph based on the identified entities and intentions were then returned to the user. The Flask framework and BSG model were utilized to develop the intelligent question answering system of TCM.@*Result@#A TCM knowledge map encompassing 3 149 entities and 6 891 relational triples based on the prescriptions and Chinese materia medica was drawn. In the question answering test assisted by a question corpus, the F1 value for recognizing entities when answering 20 types of TCM questions was 0.996 9, and the accuracy rate for identifying intentions was 99.75%. This indicates that the system is both feasible and practical. Users can interact with the system through the WeChat Official Account platform.@*Conclusion@#The BSG model proposed in this paper achieved good results in experiments by increasing the vector dimension, indicating the effectiveness of the joint model method and providing new research ideas for the implementation of intelligent question answering systems in TCM.
RESUMEN
Objective @#In the theories of pulse disgnosis in traditional Chinese medicine (TCM), it is emphasized that pulse manifestations at the radial artery within the wrist (called Cunkou) signify the physiological and pathological conditions of different internal organs in the human body. However, different opinions exist among researchers about the objectiveness of the pulse diagnosis technique. Some researchers mentioned that no significant differences were observed in pulse manifestations at various Cunkou areas, hence there might be some difficulty in evaluating the status of different organs through checking pulse manifestations at Cunkou. This research aims to analyze the pulse response at Cunkou from the aspect of the characteristics of tactile sensing, thus to give a preliminary explanation to the above question.@*Methods@#This research utilized the Weber-Fechner law to model the tactile sensing as a dynamic low-pass signal filter with varying bandwidths under different compression levels during pulse diagnosis. The model was applied to analyzing the clinical data collected previously by our group. The arterial pressures measured invasively with equipment from 14 patients with aorta coarctation were processed to simulate different pulse manifestations at Cun, Guan, and Chi positions of Cunkou when different compression levels were applied.@*Result@#Due to the characteristics of tactile sensing, significant variations were observed in pulse manifestations at different pulse-depths under the application of changing compression levels; while no such changes in pulse manifestations were observed from the employment of transducer only, without tactile sensing involved. The results explained why different understandings on pulse manifestations were formed between direct pulse-taking technique in TCM and modern sphygmography using transducers. The features of pulse manifestations at Cunkou, using direct pulse-taking technique but at different depths, superficial, middle, and deep positions, respectively, predicted by the developed tactile sensing model were in line with those described in TCM pulse theories.@*Conclusion@#Based on the developed tactile sensing model, this study preliminarily explains the phenomenon that pulse manifestation at Cunkou changes in response to the compression force applied during TCM pulse-taking. Integrating the tactile sensing model with the study of TCM pulse diagnosis opens a new chapter for visualizing and quantitatively interpreting pulse manifestations. This not only expands the scope of pulse diagnosis study effectively, but also provide a scientific basis for further technical upgrading and optimization of existing pulse diagnosis equipment.
RESUMEN
ObjectiveThis study aims to explore risk factors for the development of major adverse cardiovascular and cerebrovascular events （MACCEs） in middle-aged and elderly patients with type 2 diabetes mellitus complicated with stable angina pectoris （T2DM-SAP） based on real-world clinical data in traditional Chinese medicine （TCM）， so as to develop a COX proportional risk prediction model and visualize the predicted results using a nomogram. MethodBased on the clinical scientific research information sharing system， the medical records of 586 T2DM-SAP patients （45-94 years old） were collected from January 2012 to December 2019， including age， gender， course of disease， major medical history， laboratory examination， tongue image， pulse image， TCM syndrome， and major treatment drugs. MACCE outcome indicators of patients were obtained by telephone follow-up and re-hospitalization records. The data was divided into a training set and a validation set according to 7∶3. In the training set， COX univariate analysis was used to determine the risk factors for MACCE in T2DM-SAP patients， and then variables were screened by forward-backward stepwise regression method， so as to establish a MACCE risk prediction model and construct a nomogram. The predictive efficacy of the model was reflected by the C-index， receiver operating characteristic （ROC） curve， calibration map， and clinical decision curve. ResultThe history of cerebrovascular disease ［Hazard ratio （HR）=1.983， 95% confidence interval （CI，1.314-2.993）］， low-density lipoprotein （LDL-C/mmol·L-1）≥4.1［HR=2.683， 95%CI（1.461-4.925）］， dull red tongue ［HR=1.955， 95%CI（1.273-3.002）］， dull purple tongue ［HR=4.214， 95%CI（2.017-8.803）］， white thick coating ［HR=3.030， 95%CI（1.634-9.293）］， thin and weak pulse ［HR=2.233， 95%CI（1.283-3.888）］， and syndrome of wind-phlegm blocking collaterals ［HR=2.007， 95%CI（1.179-3.418）］ were found to be risk factors in middle-aged and elderly T2DM-SAP patients. Insulin ［HR=0.604， 95%CI（0.399-0.914）］， glycosidase inhibitor ［HR=0.627， 95%CI（0.409-0.962）］， and TCM treatment ［HR=0.328， 95%CI（0.214-0.503）］ were protective factors in middle-aged and elderly T2DM-SAP patients. The prediction model was constructed based on the above risk factors. The C-index of the model was 0.818 （95% CI 0.777 -0.859） in the training set and 0.814 （95% CI 0.773-0.855） in the validation set， and the change of C-index over time was plotted. The AUC of patients for 5， 10， 15 years in the training set was 0.71， 0.67， and 0.61. The AUC of patients for 5， 10， and 15 years in the validation set was 0.60， 0.68， and 0.63， respectively. The calibration map and clinical decision curves of 5， 10， 15 years were drawn in the training set and the validation set， respectively. The model was well calibrated and clinically effective. ConclusionThe history of cerebrovascular disease， LDL， dull red tongue， dull purple tongue， white thick coating， thin and weak pulse， and syndrome of wind-phlegm blocking collaterals are risk factors for MACCE in middle-aged and elderly T2DM-SAP patients， and insulin， glycosidase inhibitors， TCM treatment are protective factors for MACCE in middle-aged and elderly T2DM-SAP patients. A clinical prediction model is established accordingly. This model has good discrimination， calibration degree， and clinical effectiveness and provides a scientific basis for the prevention and treatment of MACCE in middle-aged and elderly T2DM-SAP patients.
RESUMEN
Aural vertigo frequently encountered in the otolaryngology department of traditional Chinese medicine （TCM） mainly involves peripheral vestibular diseases of Western medicine， such as Meniere's disease， benign paroxysmal positional vertigo， vestibular neuritis， and vestibular migraine， being a hot research topic in both TCM and Western medicine. Western medical therapies alone have unsatisfactory effects on recurrent aural vertigo， aural vertigo affecting the quality of life， aural vertigo not relieved after surgery， aural vertigo with complex causes， and children's aural vertigo. The literature records and clinical practice have proven that TCM demonstrates unique advantages in the treatment of aural vertigo. The China Association of Chinese medicine sponsored the "17th youth salon on the diseases responding specifically to TCM： Aural vertigo" and invited vertigo experts of TCM and Western medicine to discuss the difficulties and advantages of TCM diagnosis and treatment of aural vertigo. The experts deeply discussed the achievements and contributions of TCM and Western medicine in the diagnosis and treatment of aural vertigo， the control and mitigation of the symptoms， and the solutions to disease recurrence. The discussion clarified the positioning and advantages of TCM treatment and provided guidance for clinical and basic research on aural vertigo.
RESUMEN
A chronic refractory wound is caused by continuous skin damage. At the same time， it may be formed due to repeated infection， vascular insufficiency， diabetes， tumors， chronic osteomyelitis， and other reasons， resulting in wound repair interruption and recovery delay. Chronic refractory wound seriously affects the quality of life of patients and consumes a lot of medical resources. Polysaccharides in traditional Chinese medicine （TCM） are the effective components of most TCM. Modern pharmacological studies have found that polysaccharides contained in TCM have anti-inflammatory， antioxidant， anti-radiation， hypoglycemic， antiviral， anti-tumor， hypolipidemic， and immunomodulatory effects. Through the summary and analysis of the literature， it was found that the mechanism of polysaccharides in TCM to promote chonic refractory wound repair was mainly realized from the following aspects： firstly， regulating inflammatory cytokines like interleukin-4 （IL-4）， interleukin-10 （IL-10）， interleukin-8 （IL-8）， and tumor necrosis factor-α （TNF-α） or regulating macrophage-related inflammatory proteins and chemotactic proteins like MIP-2， MCP-1， to shorten the inflammatory period. Secondly， activating growth factors like platelet-derived growth fator （PDGF）， basic fibroblast growth factor （bFGF）， TGF-α， and vascular endothelial growth factor （VEGF） to recruit endothelial cells and fibroblasts into tissue proliferation. Thirdly， activationg VEGF and its downstream receptor vascular endothelial growth factor receptor-1 （VEGFR-1） and vascular endothelial growth factor receptor-2 （VEGFR-2）-mediatated protein kinase C/extracellular regulated kinases （PKC/ERK） signaling pathway or promoting angiogenesie and improving wound blood flow through angiotensin （ANG）. Fourthly， promoting the ablility of collagen synthesis by enhancing the secretion of hydroxyproline and hyaluronic acid （HA） from fibroblasts （FB） and regulating relevant matrix metalloenzymes and their enzyme inhibitor to regulate the extracellular matrix. Fifthly， eliminating free radiccals to reduce the damage caused by oxidative stress to tissue. Sixthly， enhancing the phagocytic ability of macrophages， the activity of natural killer cells， and the proliferation of T cells to improve the defense ability of tissue. Polysaccharides in TCM can repair wounds in many ways at the same time. Its advantage lies in the multiple targets and multiple pathways. It is expected that the research will pay more attention to the mechanism of wound repair by polysaccharide components in TCM when improving the treatment of chronic refractory wounds.
RESUMEN
ObjectiveTo objectively analyze the effects of traditional Chinese Medicine （TCM） multi-channel intervention on the ovarian function，TCM syndromes and natural conception of poor ovarian responders（kidney-Yin deficiency，liver depression and blood stasis pattern） who planned to receive another in vitro fertilization embryo transfer（IVF-ET）antagonist regimen. MethodThe 128 low-prognosis patients （kidney Yin deficiency，liver depression and blood stasis pattern） who attended the West China Second University Hospital， Sichuan University and the Hospital of Chengdu University of Traditional Chinese Medicine from August 2020 to February 2023 and met the inclusion criteria were selected，and then divided into the treatment group and the control group according to the random number table，with 64 patients in each group. The control group was treated with oral dehydroepiandrosterone（DHEA），while the treatment group was treated with multi-channel TCM（oral TCM decoction + auricular point sticking + Bushen Huoxue prescription through retention enema）. After 3 menstrual cycles，the relevant indicators for ovarian function evaluation，TCM syndrome scores and natural conception were collected from both groups. ResultCompared with the situation before treatment，the basal follicle stimulating hormone（bFSH），bFSH/basal luteinizing hormone（bLH），basal estradiol（bE2），antral follicle count（AFC），the number of oocytes obtained，the number of normal fertilization，the number of superior embryos and TCM syndrome scores in the treatment group were improved after treatment（P<0.05，P<0.01）. For the control group， the bFSH/bLH and TCM syndrome scores were increased after treatment（P<0.05）， while the bFSH，bFSH/bLH，bE2，AFC，the number of oocytes obtained，the number of normal fertilization，and the number of superior embryos showed no significant difference after treatment. Compared with the control group after treatment，bFSH，bFSH/bLH，bE2，AFC，the number of normal fertilization，the number of superior embryos and TCM syndrome scores in the treatment group were better （P<0.05，P<0.01），while there was no significant difference in the number of oocytes obtained. After treatment，there were 3 cases of natural conception in the treatment group，while there were no natural conception in the control group. ConclusionFor patients with poor ovarian response and kidney Yin deficiency，liver depression and blood stasis pattern，multi-channel intervention of TCM plus the antagonist regimen can reduce bFSH，bFSH/bLH values，improve the levels of bE2，increase AFC，the number of oocytes obtained，the number of normal fertilization and the number of superior embryos，improve ovarian function，menstruation and TCM syndromes，improve their quality of life，and even enable some patients to get pregnant naturally before re-progression and improve their pregnancy outcome.
