The zebrafish model has attracted much attention due to its strong reproductive ability, short research cycle, and ease of maintenance. It has always been an important vertebrate model system, often used to carry out human disease research. Its motor behavior features have the advantages of being simpler, more intuitive, and quantifiable. In recent years, it has received widespread attention in the study of traditional Chinese medicine(TCM)for the treatment of sleep disorders, neurodegenerative diseases, fatigue, epilepsy, and other diseases. This paper reviews the characteristics of zebrafish motor behavior and its applications in the pharmacodynamic verification and mechanism research of TCM extracts, active ingredients, and TCM compounds, as well as in active ingredient screening and safety evaluation. The paper also analyzes its advantages and disadvantages, with the aim of improving the breadth and depth of zebrafish and its motor behavior applications in the field of TCM research.

Based on the natures and flavors of herbal medicinals recorded in Shen Nong's Classic of the Materia Medica （《神农本草经》）； Miscellaneous Records of Famous Physicians （《名医别录》）， this study analyzed the characte-ristics of the natures， flavors and combination of medicinals of the two-herb compound formulas in Treatise on Cold Damage and Miscellaneous Diseases （《伤寒杂病论》）.Finally， 31 compound formulas were included， and it was found that the nature and flavor of the herbs in these two-herb compound formulas are closely related to the functions of the compound formulas， such as the common pairing of the acrid and the sweet herbs to warm yang and transform qi， the acrid and the bitter herbs in pairs to regulate and harmonize cold and heat， the sweet and the bitter in pairs to remove dampness and clear heat， the acrid and the acrid in pairs to arrest vomiting and direct qi downward， and the sour and the sweet in pairs to slow the urgent and relieve pain. Regardless of the deficiency or excess nature of the disease， the corresponding two-herb compound formulas often aim to reinforce healthy qi while eliminating pathogenic factors， with some formulas showcasing a unique correspondence between the disease pattern and the symptoms addressed.

Perimenopausal syndrome （MPS）， a common endocrine system disease， is one of the diseases responding specifically to traditional Chinese medicine （TCM）. The China Association of Chinese Medicine organized experts in endocrinology， gynecology， and interdisciplinary fields of both Western and Chinese medicine to discuss the advantages and challenges of diagnosing and treating MPS with Western medicine， TCM， and integrative medicine. Experts at the conference believe that MPS is initiated by estrogen decline and rooted in deficiency， with the pathogenesis being imbalance between Yin and Yang in the kidney. The hormone replacement therapy in Western medicine for menopause can rapidly alleviate related symptoms by quickly restoring the estrogen level and timely detect and delay complications of menopause， whereas such a therapy has certain risks， necessitating close monitoring of adverse reactions. Moreover， the various contraindications and precautions limit the clinical application of the hormone replacement therapy. TCM has advantages in synergistically alleviating symptoms such as hot flashes， sweating， sleep disorders， and emotional abnormalities of MPS without causing obvious adverse reactions. However， its efficacy is slower than the hormone replacement therapy， and the TCM evidence for preventing and treating complications of menopause remains unclear. Three suggestions were proposed for the future development of both Western and TCM for ameliorating MPS. First， an integrated diagnosis and treatment system for MPS with both Western and Chinese medicine should be established. Second， high-quality evidence-based interventions for MPS should be developed with TCM alone or in combination with Western medicine. Third， efforts should be made to promote the new TCM drug development and the interdisciplinary cooperation for treating MPS.

Background Mercury, as a global heavy metal pollutant, poses a serious threat to human health. The toxicity of mercury depends on its chemical form. Distinguishing the forms of mercury in the environment is of great significance for mercury management and reducing human mercury exposure risks. Objective To establish a non-targeted metallomics method based on synchrotron radiation X-ray fluorescence (SRXRF) spectroscopy combined with machine learning to screen inorganic mercury (IHg) or methylmercury (MeHg) exposed rice plants. Methods Rice seeds were exposed to ultra-pure water (control group), 0.1 mg·L⁻¹ IHg (IHg group) or MeHg (MeHg group) solutions, respectively. After germination, the seedlings were cultured for 21 d, and rice leaves were collected, dried, weighed, and pressed. The content of metallome in rice leaves was determined by SRXRF. Machine learning models including soft independent modeling cluster analysis (SIMCA), partial least squares discriminant analysis (PLS-DA), and logistic regression (LR) were used to classify the SRXRF full spectra of different groups and find the best model to distinguish rice exposed to IHg or MeHg. Besides, characteristic elements were selected as input parameters to optimize the model by improving computing speed and reducing model calculation. Results The SRXRF spectral intensities of the control group, IHg group, and MeHg group were different, indicating that exposure to IHg and MeHg can interfere the homeostasis of metallome in rice leaves. The results of principal component analysis (PCA) of SRXRF spectra showed that the control group could be well distinguished from the mercury exposed groups, but the IHg group and the MeHg group were mostly overlapped. The accuracy rates of the three models (PLS-DA, SIMCA, and LR) were higher than 98% for the training set, higher than 95% for the validation set, and higher than 94% for the cross-validation set. Besides, the accuracy of the LR model was higher than that of the PLS-DA model and the SIMCA model. Furthermore, the accuracy was 92.05% when using characteristic elements K, Ca, Mn, Fe, and Zn selected by LR to distinguish the IHg group and the MeHg group. Compared with the full spectra model, although the prediction accuracy of the characteristic spectral model decreased, the input parameters of the model decreased by 99.51%, and precision, recall, and F1 score were above 84.48%, indicating that the model could distinguish rice exposed to different mercury forms. Conclusion Non-targeted metallomics method based on SRXRF and machine learning can be applied for high-throughput screening of rice exposed to different forms of mercury and thus decrease the risks of people being exposed to mercury.

"State-target-cause-result"is a new clinical theory combining macroscopic and microscopic syndrome differentiation based on the holistic view of traditional Chinese medicine combined with Western medical research.The"inflammation-cancer transformation"of chronic pancreatitis is a complex pathological process that is associated with the interaction between the pancreas and various pathological factors and multiple objects,involving the imbalance of multiple homeostasis.The microscopic process of"inflammation-cancer transformation"in chronic pancreatitis is the"target,"whereas various factors that could induce its occurrence under chronic inflammatory conditions are the"state."The"inflammation-cancer transformation"of chronic pancreatitis is summarized as yin and yang imbalance,qi movement disorder,endogenous dampness,heat,blood stasis,and turbid phlegm stagnation,unresolved congestion resulting in deficiency caused by stagnation,intermingled deficiency and excess,and internal cancer toxin generation.This paper elucidates the pathogenesis and intervention strategies of the"inflammation-cancer transformation"of chronic pancreatitis from a macro perspective of"state,"focusing on reducing the impact of"state"imbalance on the"target"to establish a balanced pancreas-immune-microbiota state.The aim is to broaden the theory for exploring the mechanism and drug development related to chronic pancreatitis"inflammation-cancer transformation"in both traditional Chinese and Western medicine.

Objective To explore the incidence and risk factors of perioperative ischemic stroke in non-cardiac and non-neurosurgical surgeries and its correlation with preoperative risk assessment of cerebrovascular events,so as to guide perioperative risk management.Methods A retrospective study was conducted on 40 patients aged≥18 years who underwent non-cardiac and non-neurosurgical surgeries and experienced perioperative ischemic stroke in the First Affiliated Hospital of Henan University of Science and Technology from January 2015 to January 2022,forming the stroke group.A control group of 160 patients without perioperative ischemic stroke was selected in a 1:4 case-control ratio,matched for gender,age,date of operation,and the surgeon.Clinical data and preoperative risk assessment of cerebrovascular events(including the single or combined application of head CT/MRI,transcranial Doppler ultrasound,carotid ultrasound,and neurological consultation)of the two groups of patients were collected and statistically analyzed.Multiple logistic regression analysis was used to identify risk factors associated with perioperative ischemic stroke.Results The incidence of perioperative ischemic stroke was 0.042%.Multiple logistic analysis results showed that hypertension(OR=7.858,95%CI 2.175-28.388,P=0.002),hyperlipidemia(OR=4.457,95%CI 1.320-15.049,P=0.016),renal insufficiency(OR=8.277,95%CI 1.480-46.282,P=0.016),and intraoperative hypotension(OR=3.862,95%CI 1.211-12.317,P=0.022)were independent risk factors for perioperative ischemic stroke in non-cardiac and non-neurological surgeries;preoperative cerebrovascular risk assessment(OR=0.130,95%CI 0.031-0.542,P=0.005)was a protective factor against it.Conclusions The incidence of perioperative ischemic stroke in non-cardiac and non-neurosurgical surgery is low but has a poor prognosis.Hypertension,hyperlipidemia,renal insufficiency,and postoperative hypotension are risk factors for perioperative ischemic stroke,while preoperative cerebrovascular event risk assessment is beneficial to reducing its incidence.

Objective To investigate the effects and mechanism of Zhachong Shisanwei Pills on rats with cerebral ischemia.Methods Totally 75 rats were randomly divided into sham-operation group,model group,positive drug group(Ginaton,21.6 mg/kg),and Zhachong Shisanwei Pills low-,medium-,and high-dosage groups(81,162,324 mg/kg).Each treatment group was given the corresponding drug by gavage for 5 days.On the 6th day,a cerebral ischemia rat model was prepared by suture method.After 24 hours of modeling,the drugs were given in the same manner for 2 days.Neurological function scoring,horizontal beam walking scoring,and grip strength testing were performed on rats.TTC staining was used to detect the cerebral infarction rate,HE staining and Nissl staining were used to observe the morphology of brain tissue.TUNEL staining was used to detect the apoptosis rate of brain tissue cells.Differential genes in the treatment of cerebral ischemia using Zhachong Shisanwei Pills were screened by transcriptomics,and RT-qPCR,immunohistochemistry and Western blot were used to detect differential gene mRNA and protein expression.Results Compared with the sham-operation group,the model group rats showed a decrease in neurological function scores,horizontal beam walking scores,grip strength,an increase in cerebral infarction rate,neuronal nucleus condensation,vacuolar changes,widened intercellular spaces,the number of Nissl bodies reduced,and the apoptosis rate increased(P<0.01,P<0.001);compared with the model group,the Zhachong Shisanwei Pills medium-dosage group showed an increase in neurological function score,horizontal beam walking score,and grip strength in rats,a decrease in cerebral infarction rate,a lower degree of neuronal damage,an increase in the number of Nissl bodies,and a decrease in cell apoptosis rate(P<0.05,P<0.01).Transcriptome and bioinformatics analysis screened the Hippo signaling pathway related to the anti-cerebral ischemia effect of Zhachong Shisanwei Pills.The key genes of this pathway,mammalian sterile line 20 like kinase(MST1)1,Yes related protein(YAP)1,large tumor suppressor kinase(LATS)1,and TEA domain family member(TEAD)1 were detected.The results showed that the expression of MST1 mRNA and protein in brain tissue of model rats significantly increased,while the expressions of YAP1,LATS1,TEAD1 mRNA and protein significantly decreased;Zhachong Shisanwei Pills could down-regulate the expression of MST1 in brain tissue of model rats,and up-regulate the expressions of YAP1,LATS1 and TEAD1.Conclusion Zhachong Shisanwei Pills may exert anti-cerebral ischemia effects through the Hippo signaling pathway.

Objective:To investigate the clinical effect of extraperitoneal robot-assisted laparoscopic modified Y-V plasty(LMYVP)in the treatment of refractory bladder neck contracture(BNC).Methods:We retrospectively analyzed the clinical data on 10 cases of refractory BNC after transurethral resection of the prostate between September 2020 and January 2023,all with a history of recurrent urethral dilatation and at least two failures in transurethral surgical treatment of scarring.After definite diagnosis and re-moval of some of the scar tissues to flatten the elevated bladder neck under the cystoscope,we performed robot-assisted LMYVP using the da Vinci Si robotic system and a four-port extraperitoneal approach.The surgical procedure involved an inverted T-shaped incision in the bladder neck and urethral stricture ring,an inverted V-shaped excision of the scar area at the 3-9 o'clock position on the ventral side of the prostatic urethra,continuous full-layer suturing of the bladder neck and inverted V-shaped urethra with 3-0 barbed thread,and indwelling of an F20 silicone catheter for 2 weeks.At 3 months after surgery,we performed cystoscopic examination,measured the maximum urinary flow rate(Qmax),and obtained the IPSS and quality of life(QOL)scores of the patients.Results:Operations were successfully completed in all the cases.At 3 months after surgery,the patients showed significantly increased Qmax([3.65±1.27]vs[20.3±1.77]ml/s,P＜0.05),IPSS(5.9±2.02 vs 30±1.15,P＜0.05)and QOL score(1.3±0.95 vs 5.2±0.79,P＜0.05)compared with the baseline.Cystoscopy revealed a wide and flat bladder neck with good survival and hemody-namics of the bladder flap.All the patients met the criteria for clinical cure at a median follow-up of 13.2 months.Conclusion:Extraper-itoneal robot-assisted LMYVP provides a new strategy for urinary tract reconstruction in the management of refractory BNC,with the ad-vantages of minimal invasiveness,high efficiency and high success rate.

Objective:To systematically evaluate the efficacy of different kinds of smoking cessation drugs by network Meta-analysis.Methods:Literature was retrieved from PubMed, Web of Science, Embase, Cochrane Library, CBM, CNKI, VIP, Wan fang database, from the establishment of the database to November 2022, and randomized controlled trials (RCT) about bupropion, varenicline, nicotine replacement therapy (NRT) versus placebo in the treatment of smoking patients were collected. After data extraction from included literature which met inclusion criteria, and quality evaluation with Cochrane 5.1 risk bias evaluation tool, network Meta-analysis was performed by Stata15.1 software.Results:A total of 19 RCTs, involving 6106 patients and three interventions measures (bupropion, varenicline, NRT) and one control measure (placebo) were included. The results of network Meta-analysis showed that in terms of short-term abstinence rate, varenicline [ OR=4.21, 95% CI (2.32, 7.63)], bupropion [ OR=2.81, 95% CI(1.05, 7.54)] were better than placebo ( P<0.05). The surface under the cumulative ranking area (SUCRA): varenicline (90.2%)>bupropion (64.8%)>NRT (41.7%)>placebo (3.2%). In terms of the long-term abstinence rate, varenicline [ OR=3.06, 95% CI (1.59, 5.90)], NRT [ OR=3.39, 95% CI (2.20, 5.21)] were better than placebo ( P<0.05). SUCRA: varenicline (83.8%)>NRT (73.9%)>bupropion (37.2%)>placebo (5.2%). Conclusion:The existing evidence shows that compared with bupropion, NRT, varenicline has the best effect on quitting smoking, but more high-quality randomized trial evidence is needed for verification.
