Objective: We employed Mendelian randomization (MR) to test the traditional Chinese medicine (TCM) theory of emotional pathogenesis concept and explore the causal relationship between negative emotions and chronic obstructive pulmonary disease (COPD). Methods: Data of negative emotions, bronchitis, emphysema, and C-reactive protein (CRP) levels were downloaded from genome-wide association study (GWAS) public database for a two-sample MR analysis. Independent single-nucleotide polymorphisms (SNPs) associated with negative emotions, bronchitis, and emphysema were selected as instrumental variables. Primary causal estimates were derived using inverse-variance weighting (IVW), supplemented by weighted median (WM), and simple mode (SM) methods. Sensitivity analyses included MR-Egger regression and MR-PRESSO to assess pleiotropy, Cochran’s Q test for heterogeneity, and multivariate MR to adjust for smoking. Mediation analysis evaluated the role of inflammatory markers. Reverse MR was tested for bidirectional causality. Weak instrument bias was mitigated via F-statistic thresholds (> 10). All analyses were conducted in RStudio. Results: MR analysis identified significant causal effects of several negative emotions on COPD. Genetically, the IVW analysis of seen doctors for nerves anxiety tension or depression [ORIVW = 1.006, 95% CI = (1.002, 1.010), P = 0.002], sensitivity/hurt feelings [ORIVW = 1.024, 95% CI = (1.004, 1.044), P = 0.017], and irritability [ORIVW = 1.019, 95% CI = (1.003, 1.035), P = 0.019 were robustly associated with increased risks of COPD. No heterogeneity was detected among the different instrumental variables (IVs) for depression (P = 0.655) and irritability (P = 0.163). MR-Egger regression intercepts for all emotional exposures were close to zero and statistically non-significant, indicating no evidence of directional pleiotropy. The horizontal pleiotropy results showed that except for worry (MR-PRESSO P = 0.006), other emotion exposures confirming no substantial pleiotropic bias. Multivariable MR demonstrated that anxiety remained independently associated with COPD after adjusting for smoking (P = 0.002), while associations with other negative emotions were attenuated post-adjustment. The mediation analysis revealed that CRP mediated 3.93% of the total effect of anxiety on COPD. However, reverse MR analysis found no evidence of reverse causality. Conclusion This study confirmed the causal effects of negative emotions on COPD through MR analysis and revealed that negative emotions may trigger CRP production, which plays an essential mediating role in this relationship. This study provides a reliable modern theoretical basis for emotion theory in TCM.

Pulmonary complications， the most common postoperative complications of lung cancer， not only affect the quality of life of the patients after surgery but also increase the prognostic risks of postoperative recurrence and metastasis， threatening the life safety. At present， a multidisciplinary model of diagnosis and rehabilitation with integrated traditional Chinese medicine （TCM） and Western medicine has been initially formed under the guidance of the concept of rapid rehabilitation post operation for lung cancer. However， the treatment that only aims at shortening hospital stay and reducing the incidence of postoperative complications does not pay enough attention to the postoperative functional rehabilitation of the lung and the impact of follow-up adjuvant therapy， which affects the completeness of rehabilitation. This paper classifies the typical postoperative symptoms and manifestations of lung cancer into five groups： Lung system， emotion， digestive tract， pain， and nerve. On this basis， this paper summarizes the three core pathogeneses of postoperative complications of lung cancer as failure of Qi to ascend and descend leading to insecurity of defensive exterior， vessel block leading to Qi stagnation and fluid retention， and lung Qi deficiency leading to spleen and kidney deficiency. Accordingly， this paper proposes the treatment principle of protecting healthy Qi and treating Qi with the core of descending-tonifying-ascending-dispersing Qi and puts forward three treatment methods. The first is replenishing Qi and consolidating exterior， and expelling phlegm and regulating lung. The second is replenishing Qi and promoting blood flow to resolve stasis and relieving pain. The third is replenishing Qi and tonifying lung， and invigorating spleen and tonifying kidney. Furthermore， this paper elaborates on the pathogenesis and treatment principles of four common postoperative complications： Lung infection， pleural effusion， atelectasis， and bronchopleural fistula. On the basis of Western medical treatment， the TCM treatment characteristics of treating symptoms in the acute phase and eradicating the root cause in the chronic phase should be played. While dispelling the pathogen， measures should be taken to protect the healthy Qi， including tonifying lung Qi， regulating spleen Qi， and replenishing kidney Qi. This study summarizes the pathogenesis and treatment strategy of common postoperative complications of lung cancer according to the principle of protecting healthy Qi and treating Qi， aiming to provide guidance for the future treatment of postoperative complications of lung cancer.

Objective:To establish and assess the precision of pre-surgical condyle position planning using mandibular movement trajectory data for orthognathic surgery.Methods:Skull data from large-field cone beam computed tomography(CBCT)and dental oral scan data were imported into IVSPlan 1.0.25 software for 3D reconstruction and fusion,creating 3D models of the maxilla and mandible.Trajectory da-ta of mandibular movement were collected using a mandibular motion recorder,and the data were inte-grated with the jaw models within the software.Subsequently,three-dimensional trajectories of the con-dyle were obtained through matrix transformations,rendering them visually accessible.A senior oral and maxillofacial surgeon with experience in both diagnosis and treatment of temporomandibular joint disease and orthognathic surgery selected the appropriate condyle position using the condyle movement trajectory interface.During surgical design,the mobile mandibular proximal segment was positioned accordingly.Routine orthognathic surgical planning was completed by determining the location of the mandibular distal segment,which was based on occlusal relationships with maxilla and facial aesthetics.A virtual mandible model was created by integrating data from the proximal and distal segment bone.Subsequently,a solid model was generated through rapid prototyping.The titanium plate was pre-shaped on the mandibular model,and the screw hole positions were determined to design a condylar positioning guide device.In accordance with the surgical plan,orthognathic surgery was performed,involving mandibular bilateral sagittal split ramus osteotomy(SSRO).The distal segment of the mandible was correctly aligned inter-maxillary,while the proximal bone segment was positioned using the condylar positioning guide device and the pre-shaped titanium plate.The accuracy of this procedure was assessed in a study involving 10 patients with skeletal class Ⅱ malocclusion.Preoperative condyle location planning and intraoperative po-sitioning were executed using the aforementioned techniques.CBCT data were collected both before the surgery and 2 weeks after the procedure,and the root mean square(RMS)distance between the preope-rative design position and the actual postoperative condyle position was analyzed.Results:The RMS of the condyle surface distance measured was(1.59±0.36)mm(95％CI:1.35-1.70 mm).This value was found to be significantly less than 2 mm threshold recommended by the expert consensus(P＜0.05).Conclusion:The mandibular trajectory may play a guiding role in determining the position of the mandibular proximal segment including the condyle in the orthognathic surgery.Through the use of a con-dylar positioning guide device and pre-shaped titanium plates,the condyle positioning can be personalized and customized with clinically acceptable accuracy.

Objective To make an epidemiological investigation on traditional Chinese medicine(TCM)dampness syndrome manifestations in the population at risk of cerebrovascular diseases in Guangdong area.Methods A cross-sectional study was conducted to analyze the clinical data related to the risk of cerebrovascular diseases in 330 Guangdong permanent residents.The diagnosis of dampness syndrome,quantitative scoring of dampness syndrome and rating of the risk of stroke were performed for the investigation of the distribution pattern of dampness syndrome and its influencing factors.Results(1)A total of 306(92.73%)study subjects were diagnosed as dampness syndrome.The percentage of dampness syndrome in the risk group was 93.82%(258/275),which was slightly higher than that of the healthy group(48/55,87.27%),but the difference was not statistically significant(χ2 = 2.91,P = 0.112).The quantitative score of dampness syndrome in the risk group was higher than that of the healthy group,and the difference was statistically significance(Z =-2.24,P = 0.025).(2)Among the study subjects at risk of cerebrovascular disease,evaluation time(χ2 = 26.11,P = 0.001),stroke risk grading(χ2= 8.85,P = 0.031),and history of stroke or transient ischemic attack(TIA)(χ2 = 9.28,P = 0.015)were the factors influencing the grading of dampness syndrome in the population at risk of cerebrovascular disease.Conclusion Dampness syndrome is the common TCM syndrome in the population of Guangdong area.The manifestations of dampness syndrome are more obvious in the population with risk factors of cerebrovascular disease,especially in the population at high risk of stroke,and in the population with a history of stroke or TIA.The assessment and intervention of dampness syndrome should be taken into account for future project of stroke prevention in Guangdong.

Ubiquitination, a diverse post-translational modification, is carried out by enzymes including E1-activating enzymes, E2-conjugating enzymes, E3 ligases, and deubiquitinating enzymes (DUBs). Ubiquitin itself possesses 7 lysine residues and N-terminal methionine, allowing for the formation of polyubiquitin chains with different lengths and linkages. These chains exhibit various topologies that can be recognized by proteins containing ubiquitin-binding domain, thereby transmitting distinct cellular signals. To unravel the physiological mechanisms associated with ubiquitin, numerous ubiquitin probes have been developed. This review provides an overview of recent advancements in the field of ubiquitin probes, focusing on activity-based and affinity-based probes. Activity-based probes are designed to covalently bind to DUBs, E1s, or E3s, enabling the identification and characterization of these enzymes. Affinity-based probes, on the other hand, selectively bind to ubiquitin-binding domains, facilitating the identification of proteins that interact with ubiquitin. Moreover, this review comprehensively discusses the synthetic methodologies employed for the acquisition of ubiquitin probes. These includes meticulous discussions on the synthesis of individual monomeric modules, the establishment of isopeptide linkages, as well as the incorporation of reactive functional groups. Additionally, the review explores the emerging area of cell-penetrating ubiquitin probes and highlights their latest applications in living cells. These probes incorporate cell-penetrating peptides to enable their internalization into cells, allowing for direct visualization and manipulation of ubiquitin-modified proteins within their native environment. Overall, this review offers insights into the design, synthesis, and applications of ubiquitin probes, highlighting their significance in elucidating ubiquitin-mediated cellular processes.

Based on the theory of "one qi circulation" founded by HUANG Yuanyu， the core disease mechanism of colorectal cancer is the innate spleen deficiency and stomach qi failing to bear downward， which leads to the turbidity assemble in large intestine， forming the carcinoma toxin， and ultimately transforms into colorectal cancer. The treatment should base on recovering the circulation of qi， Huangya Decoction （黄芽汤） as the basic formula， the circulation of qi ascending and descending as the base， adjusting ascending and descending together with Xiaqi Decoction （下气汤）， and differentiating the syndrome on yin-yang excess-deficiency； for spleen-kidney yang deficiency syndrome， treated with Tianhun Decoction （天魂汤） to supplement liver， kidney and assist yang； for liver-kidney yin deficiency syndrome， treated wtih Dipo Decoction （地魄汤） to supplement lung， kidney， and assist yang. They jointly prompt one qi circulation to provide the thoughts for the treatment of colorectal cancer by traditional Chinese medicine.

BACKGROUND:Our previous studies have confirmed that H2O2 and ginsenoside Rg1 can cause changes in reactive oxygen species levels in human periodontal ligament cells,but the correlation of reactive oxygen species with apoptosis and autophagy remains unclear. OBJECTIVE:To explore the effect and mechanism of ginsenoside Rg1 on H2O2-induced apoptosis and autophagy of human periodontal ligament cells. METHODS:Human periodontal ligament cells were divided into control group,H2O2 group and H2O2+Rg1 group.Ginsenoside Rg1(50 μmol/L)was pre-incubated for 24 hours and H2O2 was treated for 2 hours(500 μmol/L).CCK-8 assay was used to detect the proliferation ability of the cells.A fluorescent probe DCFH-DA was used to detect the reactive oxygen species level of the cells.qRT-PCR and western blot assay were used to detect heme oxygenase 1,apoptosis-related factor Caspase-3,Bax,anti-apoptotic factor Bcl-2,autophagy Beclin-1,P62,LC3,pathway-related factors phosphatidylinositol-3-kinase(PI3K),protein kinase B(AKT),mammalian target of rapamycin(mTOR)mRNA and protein expression. RESULTS AND CONCLUSION:(1)Compared with the control group,the proliferation activity of human periodontal ligament cells in the H2O2 group decreased.Compared with the H2O2 group,the proliferation activity of human periodontal ligament cells increased in the H2O2+Rg1 group.(2)Compared with the control group,the expression of reactive oxygen species and heme oxygenase-1 increased in the H2O2 group.Compared with the H2O2 group,the expression of reactive oxygen species and heme oxygenase-1 decreased in the H2O2+Rg1 group.(3)Compared with the control group,the expression of Caspase-3,Bax,Beclin-1 and LC3 increased,while the expression of Bcl-2 and P62 decreased in human periodontal ligament cells of the H2O2 group.Compared with the H2O2 group,the expressions of Caspase-3,Bax,Beclin-1 and LC3 decreased,and the expressions of Bcl-2 and P62 increased in the H2O2+Rg1 group.(4)Compared with the control group,the expressions of PI3K,AKT and mTOR decreased in human periodontal ligament cells of the H2O2 group.Compared with the H2O2 group,the expressions of PI3K,AKT and mTOR increased in human periodontal ligament cells of the H2O2+Rg1 group.(5)These results suggest that ginsenoside Rg1 can inhibit H2O2-induced apoptosis and autophagy in human periodontal ligament cells by reducing the content of reactive oxygen species and down-regulating the related factor expression of the PI3K/AKT/mTOR pathway.

Endo-periodontal lesions(EPLs)involve both the periodontium and pulp tissue and have complicated etiologies and pathogenic mechanisms,including unique anatomical and microbiological characteristics and multiple contributing factors.This etiological complexity leads to difficulties in determining patient prognosis,posing great challenges in clinical practice.Furthermore,EPL-affected teeth require multidisciplinary therapy,including periodontal therapy,endodontic therapy and others,but there is still much debate about the appropriate timing of periodontal therapy and root canal therapy.By compiling the most recent findings on the etiology,pathogenesis,clinical characteristics,diagnosis,therapy,and prognosis of EPL-affected teeth,this consensus sought to support clinicians in making the best possible treatment decisions based on both biological and clinical evidence.

OBJECTIVE To establish a rapid nondestructive detection method for the sporoderm-broken rate of Ganoderma lucidum spore powder by hyperspectral technology combined with chemometrics. METHODS Hyperspectral images of Ganoderma lucidum spore powder samples with different sporoderm-broken rates were collected, and spectral data in the visible-shortwave near-infrared band(397−1 004 nm) range of each sample were calculated after selecting the region of interest. Compared 6 spectral preprocessing methods[standard normal variable transformation, multivariate scattering correction, Savitsky-Golay(SG) smoothing, wavelet transform, SG smoothing+standard normal variable transformation, and SG smoothing+multivariate scattering correction], 5 characteristic band extraction methods(competitive adaptive reweighting, successive projections algorithm, uninformative variables elimination, least angle regression, and genetic algorithm), and 5 algorithms(partial least squares regression, support vector regression, extreme learning machine, multilayer perceptron, and LightGBM) for constructing quantitative correction models to predicts performance. RESULTS The optimal combination was SG smoothing+competitive adaptive reweighted feature band selection+partial least squares. The quantitative correction model established based on the algorithm combination achieved a prediction set coefficient of 0.868 2, and a root mean square error of 0.011 7 for Ganoderma lucidum spore powder samples with a sporoderm-broken rate range of 90%−100%. The selected optimal algorithm combination was applied to construct a quantitative correction model with a sporoderm-broken rate range of 0−100%, the coefficient of determination for the test set was 0.973 1 and the root mean square error was 0.049 3, showing good generalization ability. CONCLUSION The established quantitative detection model can realize the rapid and non-destructive detection of the sporoderm-broken rate of Ganoderma lucidum spore powder, which provides technical support for the quality control of Ganoderma lucidum spore powder and its products.
