ABSTRACT

Objective:To record stereoelectroencephalography (SEEG) data and to induce cortical electrical stimulation in children with tuberous sclerosis complex (TSC), thus exploring the epileptogenicity of different types of cortical tubers.Methods:The SEEG recording and cortical electrical stimulation data of 50 children with TSC who underwent preoperative evaluation for drug-resistant epilepsy at Epilepsy Center, Tsinghua University Yuquan Hospital from November 2016 to September 2022 were retrospectively analyzed, involving 27 boys and 23 girls with the age of (5.5±3.4) years.According to the results of 3.0T magnetic resonance imaging (3T-MRI) and computed tomography(CT), cortical tubers were classified.The incidences of electroclinical seizures, electrical seizures and seizures induced by cortical electrical stimulation in different types of tubers recorded by SEEG were analyzed, and the differences in the proportion of the above seizures among different types of tubers were compared using the Fisher′ s exact test. Results:A total of 303 cortical tubers were explored using SEEG in 50 patients.The tubers were divided into 6 types, including Type A, B, C, D and E, and focal cortical dysplasia like (FCD-like) type, among which Type E was for the first time proposed in the world.Among these explored tubers, 7 tubers had electrical seizures, and 57 tubers had electroclinical seizures.A total of 64 tubers (21.1%) were epileptogenic.The incidence of epileptogenic tubers in Type A-E and FCD-like type were 3.6%, 1.4%, 19.0%, 77.8%, 77.5%, and 90.0%, respectively. Fisher′ s exact test and Bonferroni correction were performed for pairwise comparisons( P<0.003). There was no significant difference in the incidence of epileptogenic tubes among Type A, B and C. There was significant difference in the incidence of epileptogenic tubes between Type A-C with Type D, Type E and FCD-like type, respectively.There was no significant difference in the incidence of epileptogenic tubes between Type D, Type E and FCD-like like.Electrical stimulation-induced seizures occurred in 36 cortical tubers (11.9%). The positive rate of electrical stimulation seizures in Type A-E and FCD-like type were 0.7%, 1.4%, 4.8%, 44.4%, 45.0%, and 70.0%, respectively.There was significant difference in the positive rate of electrical stimulation seizures between Type A-B and Type D, Type E and FCD-like type, respectively, so as that between Type C versus Type E and FCD-like type.No significant difference in the positive rate of electrical stimulation seizures was found between other pairwise comparisons. Conclusions:This study proposed a new classification of cortical tubers in TSC patients, and Type E is proposed for the first time in the world.SEEG records confirmed great differences in epileptogenicity indifferent types of cortical tubers.Type D, Type E and FCD-like type have higher epileptogenicity, which is of great value for the preoperative evaluation of TSC epilepsy surgery and the placement strategy of SEEG electrodes.

ABSTRACT

@#Abstract: Objective To investigate the composition and diversity of midgut microbial community of Haemaphysalis longicornis infected with severe fever with thrombocytopenia syndrome virus (SFTSV). Methods The midgut DNA of three group Haemaphysalis longicornis infected with SFTSV was extracted, and the 16S rDNA gene of the sample was sequenced by HiSeq platform. The composition and diversity of endosymbiotic microbial community were clarified by OTU cluster analysis and alpha diversity analysis. Results The midgut microbial clusters of the three groups infected with SFTSV were 143, 113, 163 OTUs respectively; the sparsity curve and abundance grade curve showed that the data had sufficient sequencing depth, and the midgut of Haemaphysalis longicornis infected with SFTSV was rich in microbial composition, but the species distribution was uneven. The analysis of microbial community composition showed that Proteobacteria, Firmicutes and Actinobacteria were the main dominant bacteria at the phyla level. At the class level, Gammaproteobacteria, Bacilli, Betaproteobacteria and Actinomycetia were the main dominant bacteria. At the order level, Legionellales, Bacillales, Burkholderiales and Actinomycetales were the main dominant orders. At the family level, Coxiellaceae, Bacillaceae, Moraxellaceae and Rhodococcaceae were the main dominant families. At the genus level, the relative abundance of Coxiella was the highest, followed by Aeribaillus and Azonexus. Alpha diversity analysis showed that the average Shannon index was 139.67, the average Simpson index was 0.48, the average Chao index was 145.06, and the average ACE index was 147.11. Conclusions The species diversity of intestinal microorganisms in Haemaphysalis longicornis infected with SFTSV is rich. The results provide a basis for further exploring the interaction between intestinal microbes of Haemaphysalis longicornis and SFTSV and developing new ideas for the prevention and control of ticks and tick-borne diseases.

ABSTRACT

Objective:To evaluate the autogenous arteriovenous fistula(AVF) insufficiency by ultrasound monitoring of brachial artery resistance index(RI).Methods:The brachial artery RI and blood flow volume(FV) data of 828 patients who underwent color-Doppler ultrasound detection after AVF in the General Hospital of Western Theater Command from January 2019 to June 2021 were retrospectively analyzed. The patients were grouped according to the adequacy of clinical dialysis, including 668 patients in the group with normal AVF function and 160 patients in the group with insufficient AVF function. The general information and ultrasonic measurement parameters were compared between the two groups. The correlation between brachial artery FV and RI was analyzed. The evaluation of brachial artery flow RI for AVF insufficiency was analyzed by ROC curve.Results:There were statistically significant differences between the two groups in brachial artery RI and FV(both P<0.001). The results of Pearson correlation analysis showed that brachial artery FV was negatively correlated to RI ( r=-0.657, P<0.001). The area under ROC curve for assessing AVF function by brachial artery RI was 0.970, with 95% CI was 0.955-0.986, the optimal cut-off value was 0.665, and the sensitivity and specificity were 0.888 and 0.955, respectively. Conclusions:Brachial artery RI in patients with AVF insufficiency is significantly higher than that in patients with normal AVF function. The optimal cutoff value of brachial artery RI can be used as an evaluation parameter for rapid screening of AVF function.

ABSTRACT

Objective:To analyze the characteristics of stereoelectroencephalography (SEEG) in children with drug-resistant epileptic spasms (ES), and to explore the surgical strategy of children with spastic seizure under the guidance of SEEG.Methods:The clinical data of 156 children with ES who were preoperatively evaluated in the Department of Neurosurgery Ward 3, Tsinghua University Yuquan Hospital from January 2014 to December 2021 were retrospectively reviewed.All children were evaluated in the second stage of stereotactic electrode placement after a non-invasive preoperative evaluation.The characteristics of intracranial EEG, surgical strategy and prognosis were analyzed.Results:A total of 19 eligible children were included, involving 13 boys and 6 girls.The age of first onset and surgical age of them ranged 1 month to 4 years, and 2 years to 13 years, respectively.The SEEG was divided into 3 types in children with ES at the onset.Five children were SEEG type A, presenting with the focal seizure discharges at the beginning and a gradual propagation to widespread fast-wave bursts.Ten children were SEEG type B, presenting a focal leading spike followed by diffused fast-wave bursts.Four children were SEEG type C, presenting a diffuse fast wave rhythm onset.Although some electrode discharges appeared slightly " leading", they covered more than one brain region.After focal resection or thermocoagulation, 13/19 patients did not have the onset of seizures, and 5/19 and 8/19 were graded as SEEG type A, and B, respectively.During the intermittent period of SEEG attacks in children with SEEG type A and B, a significant phenomenon of focal epileptic discharge consistent with the onset of the attack was observed, and surgical removal of these areas effectively controlled spastic seizures.Conclusions:Epileptic spasms may be triggered by a focal neocortical discharge.Intracranial EEG showed that the focal seizure onset evolves into spasm or a focal " leading spike" is a good indicator of surgical prognosis.

ABSTRACT

This study first optimized the processing technology for Zhangbang vinegar-processed Olibanum and investigated its in vitro anticoagulant activity. A multi-index-response surface methodology was used, with yield, powder yield, and the relative percentage of the content of six non-volatile components [11-keto-boswellic acid(KBA), 3-acetyl-11-keto-boswellic acid(AKBA), β-elemonic acid, α-boswellic acid(α-BA), β-boswellic acid(β-BA), and α-acetyl-boswellic acid(α-BA)] and three volatile components(octyl acetate, incensole, and incensole acetate) as evaluation indicators. Analytical hierarchy process(AHP) combined with coefficient of variation method was used to calculate the weight of each indicator and calculate the comprehensive score(OD). Furthermore, response surface methodology was used to investigate the effects of frying temperature(A), burning time(B), rice vinegar dosage(C), and steaming time(D) on the processing technology of vinegar-processed Olibanum. Vinegar-steamed Olibanum was prepared according to the optimal processing technology for in vitro anticoagulant experiments. The results showed that the weights of octyl acetate, incensole, incensole acetate, KBA, AKBA, β-elemonic acid, α-BA, β-BA, α-ABA, yield, and powder yield were 0.358 2, 0.104 5, 0.146 4, 0.032 9, 0.123 7, 0.044 4, 0.022 1, 0.042 2, 0.110 1, 0.012 2, and 0.0032, respectively. The optimal processing technology for Zhangbang vinegar-processed Olibanum was as follows. Olibanum(50 g) with a particle size of 1-5 mm was continuously stir-fried at a low heat of 150-180 ℃ until in a gel-like state, ignited for burning for 15 s, sprayed with 7.5 g of rice vinegar(15%), and steamed for 3 min without fire. Subsequently, the cover was removed, and the product was continuously stir-fried at 150-180 ℃ until in a soft lump shape, removed, cooled, and crushed. The results of the in vitro anticoagulant experiments showed that compared with the blank group, both Olibanum and vinegar-processed Olibanum significantly prolonged the activated partial thromboplastin time(APTT), thrombin time(TT), and prothrombin time(PT) of rat platelet-poor plasma(PPP), and the effect of vinegar-processed Olibanum was significantly better than that of Olibanum(P<0.05). The optimized processing technology for Zhangbang vinegar-processed Olibanum is stable, feasible, and beneficial for the further development and utilization of Olibanum slices. At the same time, using the content of volatile and non-volatile components, yield, and powder yield as indicators, and verifying through pharmacological experiments, the obtained results are more reasonable and credible, and have positive guiding significance for the clinical application of characteristic processed Olibanum products.

ABSTRACT

Reflex epilepsy is a type of partial or generalized seizure induced by specific or nonspecific stimulation in individuals without a prior history of seizures. Mahjong epilepsy is a special form of complex reflex epilepsy induced by playing or watching mahjong, with a low incidence rate and complex pathogenesis. Due to the lack of comprehensive understanding, clinical studies of mahjong epilepsy are still mainly based on case reports. Now, we will analyze and summarize the etiology, pathogenesis, clinical diagnosis, electroencephalogram, treatment, and prognosis of mahjong epilepsy to raise awareness of mahjong epilepsy among clinical medical workers.

ABSTRACT

This study aims to develop the pre-column derivatization high performance liquid chromatography(HPLC) method for the determination of 16 kinds of amino acids in Eucommia ulmoides leaves, and compare the content of amino acids in the leaves harvested at different time and under leaf-oriented cultivation mode(LCM) and arbor forest mode(AFM). The HPLC conditions are as below: phenyl isothiocyanate(PITC) as pre-column derivatization agent, Agilent ZORBAX C_(18 )column(4.6 mm×250 mm, 5 μm), mobile phase A of acetonitrile-water(80∶20), mobile phase B of 0.1 mol·L~(-1) sodium acetate solution-acetonitrile(94∶6), gradient elution, flow rate of 1.0 mL·min~(-1), injection volume of 5 μL, column temperature of 40 ℃, and detection wavelength of 254 nm. The HPLC profile indicated well separation of 16 kinds of amino acids and the amino acid content in E. ulmoides leaves was up to 16.26%. In addition, the amino acid content in leaves of E. ulmoides under LCM was higher than under AFM. The amino acid content varied with the harvesting time. Through orthogonal partial least squares discriminant analysis, the amino acids of E. ulmoides under LCM and AFM were compared, which can distinguish the leaves under LCM from those under AFM. Principal component analysis was applied to comprehensively score the amino acids of E. ulmoides leaves. The results showed that the score of leaves under LCM was higher than that under AFM. Nutritional evaluation results indicated that the proteins in E. ulmoides leaves belonged to high-quality vegetable proteins. The established method for the determination of amino acid content is reliable. With the amino acid content as index, the leaf quality of E. ulmoides under LCM is better than that under AFM. This study lays a theoretical basis for the promotion of LCM for E. ulmoides and the development of medicinal and edible products from E. ulmoides leaves.

ABSTRACT

OBJECTIVE@#To evaluate the effects of interactive dynamic scalp acupuncture (IDSA), simple combination therapy (SCT), and traditional scalp acupuncture (TSA) on motor function and gait of the lower limbs in post-stroke hemiplegia patients.@*METHODS@#A total of 231 patients with post-stroke hemiplegia was randomly divided into IDSA (78 cases), SCT (78 cases), and TSA (75 cases) groups by a random number table. Scalp acupuncture (SA) and lower-limb robot training (LLRT) were both performed in the IDSA and SCT groups. The patients in the TSA group underwent SA and did not receive LLRT. The treatment was administered once daily and 6 times weekly for 8 continuous weeks, each session lasted for 30 min. The primary outcome measures included Fugl-Meyer assessment of the lower extremity (FMA-LE), berg balance scale (BBS), modified barthel index (MBI), and 6-min walking test (6MWT). The secondary outcome measures included stride frequency (SF), stride length (SL), stride width (SW), affected side foot angle (ASFA), passive range of motion (PROM) of the affected hip (PROM-H), knee (PROM-K) and ankle (PROM-A) joints. The patients were evaluated before treatment, at 1- and 2-month treatment, and 1-, and 2-month follow-up visits, respectively. Adverse events during 2-month treatment were observed.@*RESULTS@#Nineteen patients withdrew from the trial, with 8 in the IDSA and 5 in the SCT groups, 6 in the TSA group. The FMA-LE, BBS, 6MWT and MBI scores in the IDSA group were significantly increased after 8-week treatment and 2 follow-up visits compared with the SCT and TSA groups (P<0.05 or P<0.01). Compared with pre-treatment, the grade distribution of BBS and MBI scores in the 3 groups were significantly improved at 1, 2-month treatment and 2 follow-up visits (P<0.05 or P<0.01). The SF, PROM-H, PROM-K and PROM-A in the IDSA group was significantly increased compared with the SCT and TSA groups after 8-week of treatment (P<0.05 or P<0.01). Compared with the SCT group, ASFA of the IDSA group was significantly reduced after 8-week of treatment (P<0.05). SF, SL, PROM-K and PROM-A were significantly increased at the 2nd follow-up visit whereas the ASFA was significantly reduced in the IDSA group compared with the SCT groups at 1st follow-up visit (P<0.05 or P<0.01). The SF was significantly increased in the SCT group compared with the TSA group after 8-week treatment (P<0.05). Compared with the TSA group, PROM-K, PROM-A were significantly increased at the 2nd follow-up visit (P<0.05).@*CONCLUSIONS@#The effects of IDSA on lower-limb motor function and walking ability of post-stroke patients were superior to SCT and TSA. The SCT was comparable to TSA treatment, and appeared to be superior in improving the motion range of the lower extremities. (Registration No. ChiCTR1900027206).

ABSTRACT

OBJECTIVE@#To compare the clinical effects of interactive dynamic scalp acupuncture (IDSA), simple combination therapy (SCT), and traditional scalp acupuncture (TSA) on cognitive function, depression and anxiety in patients with post-stroke cognitive impairment.@*METHODS@#A total of 660 patients with post-stroke cognitive impairment who were admitted to 3 hospitals in Shenzhen City between May 2017 and May 2020 were recruited and randomly assigned to the IDSA (218 cases), SCT (222 cases) and TSA groups (220 cases) according to a random number table. All the patients received conventional drug therapy for cerebral stroke and exercise rehabilitation training. Scalp acupuncture and computer-based cognitive training (CBCT) were performed simultaneously in the IDSA group, but separately in the morning and in the afternoon in the SCT group. The patients in the TSA group underwent scalp acupuncture only. The course of treatment was 8 weeks. Before treatment (M0), 1 (M1) and 2 months (M2) after treatment, as well as follow-up at 1 (M3) and 2 months (M4), the cognitive function of patients was assessed using the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment Scale (MoCA) Scales; depression, anxiety, sleep quality, and self-care ability of patients were assessed using Hamilton Depression Rating Scale (HAMD), Hamilton Anxiety Rating Scale (HAMA), Pittsburgh Sleep Quality Index (PSQI), and Modified Barthel Index (MBI), respectively. During this trial, all adverse events (AEs) were accurately recorded.@*RESULTS@#There were no significant differences in the MMSE, MoCA, HAMD, HAMA, PSQI, and MBI scores among the 3 groups at M0 (all P>0.05). In the IDSA group, the MMSE, MoCA and MBI scores from M2 to M4 were significantly higher than those in the SCT and TSA groups, while the HAMD, HAMA and PSQI scores were significantly reduced (all P<0.01). The changes of all above scores (M2-M0, M4-M0) were significantly superior to those in the SCT and TSA groups (all P<0.01, except M4-M0 of HAMD). At M2, the severity of MMSE, HAMD, HAMA, PSQI and MBI in the IDSA group was significantly lower than that in the SCT and TSA groups (all P<0.01). There was no serious AE during this trial.@*CONCLUSIONS@#IDSA can not only significantly improve cognitive function, but also reduce depression, anxiety, which finally improves the patient's self-care ability. The effect of IDSA was significantly better than SCT and TSA. (Trial registration No. ChiCTR1900027206).

ABSTRACT

Objective:To explore the effect and molecular mechanism of capsaicin receptor(TRPV1) on neuronal autophagy and depression-like behavior in mice.Methods:Using the method of random number table, 87 C57 male mice were divided into Sham operation group (Sham group), cerebral ischemia/reperfusion group (I/R group) and capsazepine(CPZ) preconditioning cerebral ischemia/reperfusion group (I/R+ CPZ group), with 28 mice in each group due to 3 incompatible.Mice in the I/R group were subjected to right middle cerebral artery occlusion (MCAO) to establish a cerebral ischemia-reperfusion model.Mice in the I/R+ CPZ group were injected with CPZ in the lateral ventricle prior to moulding.Mice in the Sham group had only wire plugs inserted and no arterial embolization was performed.The mNSS score was used to evaluate the degree of neurological deficits.The depression-like behaviour of mice was detected by the tail suspension test and forced swimming test.The infarct volume was observed by TTC staining.The pathological changes in the amygdala were observed by HE staining, and the expression of Beclin-1, LC3, p62 and p-PI3K, p-AKT and p-mTOR proteins were detected by Western blot.Statistical analysis was performed using SPSS 23.0 software.The t-test was used for comparison between two groups and one-way ANOVA was used for comparison of multiple group. Results:The neurological deficit score in I/R+ CPZ group (9.77±2.32) was significantly lower than that in I/R group (12.85±2.73) ( t=3.10, P<0.01). Compared with I/R group, the tail suspension immobility time of I/R+ CPZ Group ((93.28±50.69)s, (143.80±35.61) s; t=2.94, P<0.01) and the forced swimming immobility time ((139.50±13.33)s, (175.30±19.78)s; t=2.94, P<0.01) were significantly reduced.The results of TTC staining showed that the cerebral infarct volume in I/R+ CPZ group was significantly lower than that in I/R group ((19.30±5.19)%, (33.60±3.90)%; t=5.40, P<0.01). HE staining showed that the number of cells in the amygdala region of mice in the I/R+ CPZ group increased compared with that in the I/R group, with tighter arrangement and reduced deep staining of nuclear fixation.Western blot showed that compared with I/R group, the expression levels of autophagy related proteins Beclin-1( t=2.94, P<0.05) and LC3 ( t=3.16, P<0.05) in amygdala of I/R+ CPZ group were down-regulated, while the expression levels of p62( t=3.60, P<0.05), p-PI3K ( t=7.79, P<0.01), p-AKT ( t=4.15, P<0.01) and p-mTOR ( t=6.15, P<0.01) were up-regulated. Conclusion:Cerebral ischemia/reperfusion activates neuronal autophagy, and CPZ may regulate the PI3K-AKT-mTOR pathway, thus inhibits excessive activation of autophagy, thereby acting as a neuroprotective agent and improving post-stroke depression-like behaviour.

ABSTRACT

Objective To investigate the related mechanism of Slug inhibiting the proliferation of cervical cancer cell through CDH3/β-catenin/C-myc. Methods SiHa cells with stable Slug expression were screened. The expression of CDH3 in Slug-overexpressed SiHa cell was detected by RNA-sequence, Real-time PCR, Western blot and immunocytochemistry. The expression of CDH3 in SiHa and HeLa cells were detected by Western blot and immunocytochemistry. The protein level of CDH3 was up-regulated in HeLa cells or rescued in SiHa-Slug cells by transient transfection of CDH3 expression vector. The protein levels of β-catenin and C-myc were detected by Western blot, the cell growth was detected by cell counting and CCK-8 assays. Luciferase reporter assay and chromatin immunoprecipitation assay (ChIP) were performed to detect the effect of Slug on regulating the promoter region of CDH3. Results SiHa cell line with stable Slug expression was successfully constructed. Slug overexpression inhibited CDH3 expression in SiHa cells. CDH3 promoted cell proliferation and up-regulated the protein level of β-catenin and C-myc in HeLa and SiHa-Slug cells. Slug could recognize and bind to the E-boxes in the CDH3 promoter region and inhibited the transcription of CDH3 in SiHa cells. Conclusion Slug could inhibit the expression of β-catenin and C-myc by inhibiting CDH3 transcription in SiHa cells, and then attenuate the growth of SiHa cells.

ABSTRACT

BACKGROUND: Diosmetin is a bioflavonoid compound naturally abundant in citrus fruits. It is found to perform a variety of activities, while its antitumor property in osteosarcoma, a malignant tumor with unmet clinical treatment, remained unknown. METHODS: Colony formation assay, cell cycle analysis and apoptosis analysis were conducted respectively to observe the effect of diosmetin on cell proliferation and apoptosis in human osteosarcoma cells. Western blot and immunoprecipitation were used to detect the expression of apoptotic molecules and activation of STAT3/c-Myc pathway in Saos-2 and U2SO cells. RESULTS: Diosmetin significantly inhibited cell proliferation, induced cell cycle arrest at G2/M phase and promoted cell apoptosis in both Saos-2 and U2SO cells. Moreover, Diosmetin downregulated the expression of anti-apoptotic protein Bcl-xL while upregulated the levels of pro-apoptotic proteins including cleaved Caspase-3, cleaved-PARP and Bax. Furthermore, diosmetin dose-dependently inhibited STAT3 phosphorylation, reduced the expression of its downstream protein c-Myc and impeded the interaction between STAT3 molecules. CONCLUSIONS: These results suggest that diosmetin exerts anti-osteosarcoma effects by suppressing cell proliferation and inducing apoptosis via inhibiting the activation of STAT3/c-Myc signaling pathway, which provide the possibility for diosmetin to be a chemotherapeutic candidate for osteosarcoma.

ABSTRACT

Objective:To optimize the processing technology of salt-processed products of Plantaginis Semen with the specific process parameters, and verify the obtained processing technology by pharmacodynamic research, so as to provide experimental basis for the standardized production and quality control of this decoction pieces. Method:Taking composite score of appearance character score, dry extract yield and contents of three components (geniposidic acid, acteoside and isoacteoside) as index, the analytic hierarchy process (AHP)-criteria importance through intercrieria correlation (CRITIC) mixed weighting method was used to determine the weight coefficient of each index. Based on single factor tests, the response surface method was used to investigate the effects of frying time, frying temperature, salt amount and water amount on the processing technology of salt-processed products of Plantaginis Semen, and the processing technology was verified by diuretic experiment with furosemide tablets as the positive drug (administration dose of 0.01 g·kg-1). Result:The weight coefficients of geniposidic acid content, acteoside content, appearance character score, isoacteoside content and dry extract yield were 0.319, 0.193, 0.207, 0.273 and 0.008, respectively. The optimal process parameters were as following:fried at 150-180 ℃ for 10 min (obtained from the single factor tests), 100 g of Plantaginis Semen sprayed evenly with 2 g of salt (2 g of salt dissolved in 20 mL of water), and fried at 150-180 ℃ for 15 min. Compared with the blank group, both of the raw products group and the salt-processed products group could significantly increase the secretion of urine volume (P<0.01), but the excretion of Na+ in the urine of rats in the salt-processed products group was significantly higher than that in the raw products group (P<0.05). Conclusion:The optimized processing technology is simple and feasible, which can provide reference for standardizing the industrial production of salt-processed products of Plantaginis Semen. At the same time, combined with inherent quality and appearance of the salt-processed products, and verified by pharmacodynamic test, the obtained results are reasonable and reliable, which can be used for quality control of this decoction pieces.

ABSTRACT

As an important part of clinical medication, the main function of processing of traditional Chinese medicine (TCM) is to reduce toxicity and increase efficiency. The key to the best clinical efficacy of TCM after processing lies in three aspects of moderation, adaptation and timeliness, namely " three suitability" theory. In recent years, scholars have done a lot of research under the guide of " three suitability" theory, fully explaining the scientific connotation of the theory, which greatly promoted the inheritance and innovation of TCM processing. In this paper, the basic connotation of " three suitability" theory was summarized, combining with a large number of modern research reports, the pharmacodynamics and composition changes of processed drugs were analyzed and discussed under the guide of " three suitability" theory. At the end of the paper, the authors proposed that we should not only systematize the traditional processing theories, but also use modern advanced technologies to explain the essence of traditional processing theories, and to innovate and develop new processing theories, promote the development of TCM processing discipline and the progress of TCM processing industry.
