Due to the complexity of traditional Chinese medicine （TCM） interventions and the diversity of herbal components， single-omics technologies such as genomics， transcriptomics， proteomics， and metabolomics often cannot comprehensively elucidate the scientific connotations of TCM. Multi-omics technologies driven by system biology can analyze the theoretical connotations and application mechanisms of TCM from different levels such as genes， gene expression， proteins， and metabolites， in line with the holistic view of TCM， which helps to promote the modernization of TCM. By reviewing the literature on the application of omics technologies in the field of TCM， it is found that multi-omics technologies have been widely used in TCM for syndrome differentiation， evaluation of herbal quality， elucidation of pharmacological mechanisms， and drug toxicity assessment， providing comprehensive explanations of the mechanisms of action of TCM and overcoming the limitations of single-omics technologies， and having obtained significant achievements. However， multi-omics technologies also face challenges such as high cost， difficulties in data analysis due to large data volumes， and insufficient translation of research results. In the future， it is expected that through strengthening interdisciplinary cooperation， conducting long-term and dynamic clinical research， standardizing and normalizing data analysis processes， adopting appropriate and reasonable multi-omics integration patterns， establishing multi-omics databases for TCM， revealing the individualized characteristics， therapeutic mechanisms， and disease regulatory networks of TCM， the modernization of TCM will be promoted.

Objective To explore the effectiveness of using Excel sheets combined with QR codes for precision naviga-tion and location management of sterile instrument rooms in the operating room.Methods The study focused on the location management of nearly 1,000 sterile instruments in three sterile instrument rooms of our hospital.Instruments from July to Septem-ber 2023 were used as the control group,employing traditional location management methods.Instruments from October to De-cember 2023 were used as the observation group,applying Excel sheets and QR codes for precise navigation and location manage-ment.Results The time taken by new nurses and interns to find and retrieve sterile instruments decreased from(4.61±0.32 min)to(1.41±0.15 min).The accuracy of retrieving sterile instruments increased from 83.33％to 98.33％.The compliance rate for location management of sterile instruments improved from 75％to 100％.Nurse satisfaction increased from 81.67％to 96.67％,with significant differences observed(P＜0.05).Conclusion The application of Excel sheets combined with QR codes for precision navigation and location management of sterile instrument rooms in the operating room effectively reduces re-trieval time for sterile instruments,decreases error rates,optimizes management processes,enhances work efficiency,avoids sur-gical delays,ensures patient safety,minimizes conflicts between medical staff and patients,and increases nurse satisfaction.This approach is worthy of clinical promotion and application.

Background::Pulmonary embolism (PE) is a severe and acute cardiovascular syndrome with high mortality among patients with autoimmune inflammatory rheumatic diseases (AIIRDs). Accurate prediction and timely intervention play a pivotal role in enhancing survival rates. However, there is a notable scarcity of practical early prediction and risk assessment systems of PE in patients with AIIRD.Methods::In the training cohort, 60 AIIRD with PE cases and 180 age-, gender-, and disease-matched AIIRD non-PE cases were identified from 7254 AIIRD cases in Tongji Hospital from 2014 to 2022. Univariable logistic regression (LR) and least absolute shrinkage and selection operator (LASSO) were used to select the clinical features for further training with machine learning (ML) methods, including random forest (RF), support vector machines (SVM), neural network (NN), logistic regression (LR), gradient boosted decision tree (GBDT), classification and regression trees (CART), and C5.0 models. The performances of these models were subsequently validated using a multicenter validation cohort.Results::In the training cohort, 24 and 13 clinical features were selected by univariable LR and LASSO strategies, respectively. The five ML models (RF, SVM, NN, LR, and GBDT) showed promising performances, with an area under the receiver operating characteristic (ROC) curve (AUC) of 0.962-1.000 in the training cohort and 0.969-0.999 in the validation cohort. CART and C5.0 models achieved AUCs of 0.850 and 0.932, respectively, in the training cohort. Using D-dimer as a pre-screening index, the refined C5.0 model achieved an AUC exceeding 0.948 in the training cohort and an AUC above 0.925 in the validation cohort. These results markedly outperformed the use of D-dimer levels alone.Conclusion::ML-based models are proven to be precise for predicting the onset of PE in patients with AIIRD exhibiting clinical suspicion of PE.Trial Registration::Chictr.org.cn: ChiCTR2200059599.

The biological clock(also known as the circadian rhythm)is the fundamental reliance for all organisms on Earth to adapt and survive in the Earth's rotation environment.Circadian rhythm is the most basic regulatory mechanism of life activities,and plays a key role in maintaining normal physiological and biochemical homeostasis,disease occurrence and treatment.Recent studies have shown that the biologi-cal clock plays an important role in the development of oral tissues and in the occurrence and treatment of oral diseases.Since there is cur-rently no guiding literature on the research methods of biological clock in stomatology,researchers mainly conduct research based on pub-lished references,which has led to controversy about the research methods of biological clock in stomatology,and there are many confusions about how to rationally apply the research methods of circadia rhythms.In view of this,this expert consensus summarizes the characteristics of the biological clock and analyzes the shortcomings of the current biological clock research in stomatology,and organizes relevant experts to summarize and recommend 10 principles as a reference for the rational implementation of the biological clock in stomatology research.

Rheumatoid arthritis(RA)is a chronic and progressive autoimmune disease.Current clinical treatments for RA often exhibit inadequate drug responses and severe adverse effects,underscoring the necessity for alternative therapies.Baicalin,a flavonoid derived from Scutellaria baicalensis roots,possesses anti-inflammatory,antioxidant,and immunomodulatory properties.Research suggests that baicalin can inhibit the release of inflamma-tory mediators,thereby reducing inflammation.Moreover,it demonstrates antioxidant effects by decreasing reactive oxygen species production and mitigating synovial damage induced by oxidative stress.Baicalin may impede the activation of inflammatory cytokines through pathways such as NF-κB,MAPKs,and JAK-STAT signaling cascades while inducing apoptosis,regulating immune cell activity,and balancing immune mediators to impact synovitis progression.Clinically,both monotherapy with baicalin or its combination with other formulations have exhibited efficacy and safety profiles.The advancement in targeted drug delivery systems has improved its bioavailability further suggesting promising clinical applications.This review provides an overview of research progress on baicalin's mechanisms in inhibiting RA synovitis along with its clinical applications.

ObjectiveTo compare the diagnostic accuracy of five different weighting methods of Chinese medicine syndrome and then analyze their diagnostic efficacy and characteristics， by taking Diagnostic Standard for Type 2 Diabetes Mellitus （T2DM） with Dampeness-heat Syndrome （abbreviated as diagnostic standard） as an example. MethodsData from expert questionnaire on the diagnostic standard and a cross-sectional survey of 1021 patients were collected. The comparative diagnostic test accuracy （CDTA） method was used to calculate the area under the ROC curve （AUC）， area under the PR curve （AUPR）， accuracy （ACC）， sensitivity， and specificity of five commonly used weighting methods in two categories， including knowledge-driven weighting methods （expert scoring synthesis method， analytic hierarchy process， and precedence chart method） and data-driven weighting methods （logistic regression contribution method and entropy weighting method）. ResultsAmong 1021 patients with T2DM， 389 cases were diagnosed as dampness-heat syndrome. The expert scoring synthesis method， analytic hierarchy process method， and precedence chart method were basically consistent in the weight scores of each item. The expert scoring comprehensive method， analytic hierarchy process method， and entropy weighting method have a smaller difference in the weight scores of each item， while there was larger difference in the weight scores of each item of the precedence chart method and the logistic regression contribution method. The AUC （95% CI）， AUPR， ACC， sensitivity， and specifi-city of the expert scoring synthesis method were 0.913 （0.893， 0.932）， 0.851， 0.870， 0.868 and 0.875， respectively； while those of the analytic hierarchy process method were 0.910 （0.890， 0.930）， 0.838， 0.879， 0.848 and 0.896； of the precedence chart method were 0.919 （0.900， 0.937）， 0.858， 0.875， 0.871 and 0.875； of the logistic regression contribution method were 0.867 （0.842， 0.891）， 0.792， 0.853， 0.769 and 0.898； and of the entropy weighting method were 0.895 （0.873， 0.916）， 0.820， 0.869， 0.802 and 0.908. ConclusionThe knowledge-driven weighting methods are better than the data-driven weighting methods in terms of diagnostic efficacy and reflecting expert experience.

OBJECTIVE: To investigate the effect of body mass index (BMI) on the short-term effectiveness of high tibial osteotomy (HTO) in the treatment of varus knee arthritis. METHODS: The clinical data of 84 patients (84 knees) with varus knee arthritis treated with HTO between May 2016 and August 2020 were retrospectively analyzed. According to BMI, the patients were divided into normal group (32 patients in group A, BMI<25 kg/m ²), overweight group (27 patients in group B, BMI>30 kg/m ²), and obese group (25 patients in group C, BMI>30 kg/m ²). The BMI of groups A, B, and C were (23.35±0.89), (26.65±1.03), and (32.05±1.47) kg/m ², respectively. There was no significant difference ( P>0.05) in gender, age, surgical side, disease duration, and preoperative Hospital for Special Surgery (HSS) score, visual analogue scale (VAS) score, knee range of motion, and hip-knee-ankle angle (HKA) between groups. The operation time, intraoperative dominant blood loss, and the decrease of hemoglobin on the 3rd day after operation were recorded and compared between groups. The improvement of knee joint function and pain status were evaluated by knee joint HSS score, knee range of motion, and VAS score before and after operation, and measuring the HKA of patients on X-ray film. During the follow-up, the X-ray films of the knee joint were reexamined to observe the position of the internal fixator and the healing of osteotomy. RESULTS: All patients completed the operation successfully and were followed up 8-40 months (mean, 19.3 months). There was no significant difference in follow-up time, operation time, intraoperative dominant blood loss, and the decrease of hemoglobin on the 3rd day after operation between groups ( P>0.05). No operative complications such as severe vascular or nerve injury occurred. After operation, deep venous thrombosis of lower extremities occurred in 1 case in groups A and B respectively, and fat liquefaction of surgical incision occurred in 2 cases in group C. There was no significant difference in the incidence of perioperative complications between groups (3.1% vs. 3.7% vs. 8.0%) ( P=0.689). During the follow-up, there was no bone nonunion, plate fracture or loosening. At last follow-up, HSS score, VAS score, knee range of motion, and HKA significantly improved in the 3 groups when compared with those before operation ( P<0.05), but there was no significant difference in the differences of the above indexes between groups before and after operation ( P>0.05). CONCLUSION BMI does not affect the short-term effectiveness of HTO in the treatment of varus knee arthritis. HTO can be selected for overweight and obese patients after standard medical treatment is ineffective.

Objective:To evaluate the effect of controlled low central venous pressure with milrinone on laparoscopic hepatectomy in the patients.Methods:Fifty American Society of Anesthesiologists physical statusⅠ-Ⅲ patients of both sexes, aged 18-64 yr, with body mass index of 18-30 kg/m 2, of Child-Pugh grade A or B, undergoing elective laparoscopic hepatectomy, were divided into 2 groups ( n=25 each) using a random number table method: milrinone group (group M) and nitroglycerin group (group NG). After the start of surgery, milrinone 0.5 μg·kg -1·min -1 was continuously infused in group M, and nitroglycerin was continuously infused with the initial dose of 0.5 μg·kg -1·min -1 to maintain central venous pressure (CVP)≤5 mmHg in group NG.Mean arterial pressure and heart rate were recorded on admission to the operation room (T 0), at skin incision (T 1), at the beginning of liver resection (T 2), at completion of liver resection (T 3), at the end of operation (T 4), and CVP, cardiac index and stroke volume variation were recorded at T 1-4.Internal jugular vein blood samples were collected to determine the concentrations of hemogloblin, blood lactate at T 1 and T 4, and serum alanine aminotransferase, aspartate aminotransferase and creatinine concentrations at 1, 3 and 7 days after surgery.The score of blood oozing in hepatic surgical field, amount of norepinephrine used, blood loss, postoperative recovery and occurrence of complications within 7 days after operation were recorded. Results:Compared with group NG, cardiac index was significantly increased at T 2, 3, the CVP was decreased at T 2, the blood oozing score, blood loss, consumption of norepinephrine, and concentrations of blood lactate were decreased, and the postoperative drainage indwelling time was shortened in group M ( P<0.05). There was no significant difference in the serum alanine aminotransferase, aspartate aminotransferase and creatinine concentrations and incidence of postoperative complications at 1, 3 and 7 days after operation between the two groups ( P>0.05). Conclusions:Milrinone is better than nitroglycerin in decreasing central venous pressure, reducing blood loss, maintaining stable circulatory function and tissue perfusion in laparoscopic hepatectomy.

ObjectiveTo analyze the influenza surveillance data in Ezhou City， Hubei Province from 2016 to 2021， determine the epidemiological characteristics and etiological trend of influenza like illness （ILI）， and to provide scientific evidence for influenza prevention and control. MethodsThe ILI surveillance data were reported by Ezhou influenza sentinel hospitals and etiological examination results were collected by network laboratory. Influenza surveillance data from 2016 to 2021 were analyzed. ResultsFrom 2016 to 2021， the percentage of ILI visits （ILI%） in Ezhou city was 2.81% and increased over years. Majority （55.55%） of ILI cases were 0‒4 years. A total of 7 716 ILI samples were examined from 2016 to 2021， of which 1 467 tested positive with a positive rate of 19.01%. Influenza A H1N1 was mainly concentrated in January-April， A H3N2 mainly in August-December， B Victoria mainly in April-July and December-March， and B Yamagata mainly in December-February. Influenza network laboratory isolated influenza virus from the 1 467 positive samples by using MDCK cells and SPF chicken embryos. The overall isolation rate was 32.78%， which was 26.93% by MDCK cells and 5.86% by SPF chicken embryos. From 2016 to 2021， a total of 13 ILI outbreaks were reported in Ezhou City. Temporally， the outbreaks mainly occurred in winter and spring. Spatially， they were mainly in primary schools， middle schools and kindergartens. ConclusionThe winter and spring are the key time period of influenza prevention and control in Ezhou City， as they are susceptible to influenza outbreaks. Children aged 0‒14 are the key population of prevention and control. Diverse subtypes of influenza virus alternate by years， which warrants continually strengthening monitoring. Additionally， certain countermeasures against COVID-19 may be recommended in the prevention and control of influenza.

Objective:To investigate the clinical efficacy of thoracic endovascular aortic repair (TEVAR) in treating Stanford type B traumatic aortic dissection (TAD).Methods:A retrospective case series study was conducted to analyze the clinical date of 26 patients with Stanford type B TAD admitted to Nantong First People's Hospital from June 2011 to December 2019. There were 21 males and 5 females, aged 35-83 years [(56.2±12.9)years]. All patients mainly suffered from chest and back trauma and were treated with TEVAR. The operation time, intraoperative blood loss, intraoperative heparin dosage, duration of ICU stay and postoperative organ complications were collected. The changes of brain natriuretic peptide, urea nitrogen and creatinine were compared before operation and at one day after operation. The CT angiography (CTA) was performed to mainly detect the location of stent, reverse tearing, paraplegia and internal leakage at 6 months after TEVAR. The aortic CTA was used to measure the maximum diameter of aortic dissecting aneurysm and true lumen diameter of distal aorta before operation and at 6 months after operation, and the diameter changes were compared to determine the aortic remodeling after TEVAR.Results:All patients were followed up for 6-36 months [(25.9±6.3)months]. The operation time was 60-200 minutes [(96.7±30.7)minutes], the intraoperative blood loss was 20-45 ml [(31.1±6.8)ml], the dosage of heparin was 0-0.53 mg/kg [(0.4±0.1)mg/kg], the postoperative ICU stay was 1-7 days [(4.7±1.3)days]. Seven patients developed pulmonary infections after operation and showed significant improvement after closed thoracic drainage, airway management and anti-infection treatment. Two patients had abnormal renal function after operation and received medical therapy for improvement. There was no significant difference in brain natriuretic peptide, urea nitrogen and creatinine between before operation and one day after operation ( P>0.05). At 6 months after operation, the CTA showed that the stent position was satisfactory and there were no serious complications such as reverse tearing and paraplegia. Of one patient with type I endoleak, the tumor did not further expand and his condition was stable. At 6 months after operation, the diameter of dissecting aneurysm [(34.4±5.0)mm] was smaller than that before operation [(38.2±5.6)mm], the true lumen of distal stent [(26.8±4.6)mm] was larger than that before operation [(22.6±6.0)mm] ( P<0.05 or 0.01). Conclusion:For Stanford type B TAD, TEVAR has no significant effect on cardiac function and renal function, with no severe complications and good aortic remodeling.
