To implement the instructions and directives of General Secretary Xi Jinping on important documents related to traditional Chinese medicine （TCM）， adhere to the equal emphasis on TCM and Western medicine， and promote mutual complementarity， win-win cooperation， and coordinated development between TCM and Western medicine， the China Association of Chinese Medicine has organized seminars on the clinical dominant diseases of TCM in multiple professional fields， achieving a series of results. The aim is to implement the research on dominant diseases of TCM described in the Law of the People's Republic of China on Traditional Chinese Medicine and the Opinions of the Central Committee of the Communist Party of China and the State Council on Promoting the Inheritance， Innovation and Development of Traditional Chinese Medicine， thus serving the construction of advantageous specialties， clinical talent cultivation， national scientific and technological layout， and academic innovation leadership. In the field of otolaryngology， the China Association of Chinese Medicine and many Chinese and Western medicine experts across the country have conducted multiple in-depth discussions and research. At the 10^th Clinical Dominant Disease Series Youth Salon， they have elaborated and demonstrated the basic and specific suggestions and consensus on the clinical advantages of TCM and integrated TCM and Western medicine in the treatment of allergic rhinitis （AR）， making great progress. However， there is still a lack of detailed research paths. Under the guidance of the China Association of Chinese Medicine and based on the TCM Dominant Disease Series Salon for AR， this study analyzed the difficulties encountered in AR diagnosis and treatment according to the occurrence and development law of AR. Based on the advantages and characteristics of AR diagnosis and treatment by TCM and integrated TCM and Western medicine， it explored the research paradigm and technological layout points of AR and put forward suggestions. The layout involved four aspects： Optimization of the AR diagnosis and treatment system， prevention and control of comorbidities， management of chronic diseases， and a platform for TCM inheritance. Additionally， suggestions for layout and research directions， expected goals and values， and priority levels for funding were proposed. The study is expected to provide a theoretical basis and development ideas for the future prevention and treatment of AR with TCM and integrated TCM and Western medicine and promote the high-quality development of TCM.

Nonalcoholic fatty liver disease(NAFLD),also known as metabolic associated fatty liver disease(MAFLD),is one of the most common chronic liver diseases characterized by the fat accumulation in the liver and hepatocellular damage.Patients with NAFLD can manifest as simple fatty liver or non-alcoholic steatohepatitis(NASH)in the early stage,and can progress to hepatic fibrosis,hepatic cirrhosis,hepatic fail-ure,and hepatic carcinoma in the late stage.NAFLD has become the most common chronic liver disease,af-fecting more than 30%of the population worldwide,posing a threat to human health that cannot be ignored.However,the current research on NAFLD is still incomplete,and there is no ideal medication for the treat-ment of NAFLD.The clinical management of NAFLD lacks unified standards and evidence-based evidence,and the multiple comorbidities bring challenges to the clinical management of NAFLD.This article was aimed to review the research progress in the clinical management of NAFLD,including the diagnosis and non-invasive examination methods,evaluation and commonly used tools,treatments methods,advantages and disadvanta-ges,so as to provide a reference for the clinical management of NAFLD.

ObjectiveTo investigate the preventive and therapeutic effects of Tiaogan Huaxian pills combined with entecavir on hepatic fibrosis in chronic hepatitis B with liver Qi stagnation， spleen deficiency， and blood stasis syndrome and its effect on diffusion-weighted imaging （DWI）. MethodClinical data of 117 patients with liver disease who visited the Department of Hepatology at the First Affiliated Hospital of Guangxi University of Chinese Medicine from January 2021 to April 2022 were retrospectively analyzed. According to different treatment plans， they were divided into a control group （59 cases） and a treatment group （58 cases）. Both groups of patients received entecavir-based etiology treatment， and the treatment group added Tiaogan Huaxian pills on the basis of basic treatment. Both groups were treated for 24 weeks. Before and after treatment， the two groups were compared in terms of alanine aminotransferase （ALT）， advanced surgical technologies （AST）， total bilirubin （TBil）， hepatitis B virus （HBV）-DNA conversion rate， liver stiffness measurement （LSM）， four items of liver fibrosis （hyaluronidase， type Ⅲ pro-collagen， type Ⅳ collagen， and laminin）， the fibrosis index based on four factors （FIB-4）， the aspartate aminotransferase to platelet ratio index （APRI）， the apparent diffusion coefficient （ADC） value in magnetic resonance imaging （MRI）， and traditional Chinese medicine symptom scores， so as to analyze the efficacy of the two groups. ResultBefore treatment， there was no significant difference in ALT， AST， TBil， LSM， four items of liver fibrosis， FIB-4， APRI， HBV-DNA conversion rate， ADC value， and traditional Chinese medicine symptom scores between the two groups. After treatment， both groups of patients showed significant reductions in ALT， AST， TBil， LSM， hyaluronidase， type Ⅲ pro-collagen， type Ⅳ collagen， laminin， FIB-4， and APRI （P<0.05） and a significant increase in ADC value （P<0.05） and HBV-DNA conversion rate （P<0.01）. The traditional Chinese medicine symptom score of the treatment group decreased significantly （P<0.05）. Compared with the control group after treatment， the effective rate of clinical traditional Chinese medicine in the treatment group was 91.38% （53/58）， which was significantly higher than that of the control group （54.23%， 32/59） （Z=-4.325， P<0.01）. In the treatment group， ALT， AST， TBil， LSM， hyaluronidase， type Ⅲ pro-collagen， type Ⅳ collagen， laminin， FIB-4， APRI， and traditional Chinese medicine symptom scores all decreased significantly （P<0.05）， and the increase in ADC values was more significant （P<0.05）， while the difference in HBV-DNA conversion rate was not statistically significant. There were no serious adverse reactions or events in either group. ConclusionTiaogan Huaxian pills combined with entecavir have significant clinical efficacy in the treatment of hepatic fibrosis in chronic hepatitis B， which can reduce liver inflammation activity， delay hepatic fibrosis progression， and reduce traditional Chinese medicine symptom scores. It is worthy of clinical promotion and application.

Objective To investigate associations between three-dimensional(3D)morphology of cervical vertebrae and skeletal mat-uration by cone-beam computed tomography(CBCT)and establish corresponding regression models for quantitatively evaluating cervical vertebral maturation(CVM).Methods The analyzed sample consisted of 358 CBCT images(175 male,183 female),of which 277 images were randomly selected as the model development group and 81 as the performance test group.Twenty-one 3D morphological pa-rameters were defined and measured,incorporating all parts of the cervical vertebrae,including the cervical vertebral bodies,transverse processes,spinous processes,pedicles,lamina,and articular processes.The cervical vertebral maturation index(CVMI)was determined by experienced orthodontists as reference standard.Spearman's rank correlation coefficient and multivariable stepwise regression analysis were used to identify the associations and build regression models.The performance test group was employed to ex-amine each model's reliability.Paired-samples Wilcoxon signed-rank test compared the CVMI of the model prediction with the reference standard.Results Three-dimensional morphological changes in various parts of the cervical vertebrae correlated with CVMI(P＜0.05).Six 3D morphometric parameters were each recognized for male and female models,three of which were identical.The adjusted R2 was 0.899 for males and 0.902 for females,with corresponding accuracies of 85.0%and 85.4%,respectively.These models showed no difference as compared with the reference standard(P＞0.05).Con-clusion New associations were found between 3D morphology of cer-vical vertebrae and skeletal maturation.The 3D-driven morphometric CVM assessment method and corresponding regression models exhibited good credibility and high consistency with experts.

Centric relation(CR)was used in the complete dentures for edentulous jaws firstly.Then,CR was gradual-ly applied in the clinical diagnosis and treatment of dentate jaws.Regarding the application of CR in dentate jaws,there are many doubts about its rationality.For instance,should CR be the core of diagnosis and treatment of temporomandibu-lar disorders?Should CR be used as the jaw position of establishing occlusion in occlusal reconstruction?Should CR serve as the target jaw position in orthodontic treatment?Meanwhile,varieties of CR clinical applications are objective.According to the existing evidence,this paper summarizes the applicable conditions of several main clinical situations with little controversy.We preliminarily put forward the decision tree for the clinical application of CR,which can be used as a reference in clinical practice.

Three novel sesquiterpenoid heterodimers,designated as auckcostusolides A-C(1-3),were isolated from Aucklandia costus leaves.The structures of compounds 1-3 were elucidated through comprehensive spectroscopic analysis,with their absolute configurations established using a combination of X-ray single-crystal diffraction and electronic circular dichroism(ECD)calculations.Notably,compounds 1 and 2,despite sharing identical planar structures derived from two identical sesquiterpenoids,exhibited oppos-ite configurations at C-11 and C-8'.This configurational difference can be attributed to distinct Diels-Alder cycloaddition processes between the sesquiterpenoid monomers.Additionally,the cytotoxic effects of compounds 1-3 were evaluated against colorectal can-cer HCT116 cells,fibrosarcoma HT1080 cells,and hepatocellular carcinoma HepG2 cells.Compounds 1-3 induced cell death was characterized by endoplasmic reticulum(ER)swelling and cytoplasmic vacuolization,typical morphological changes associated with paraptosis.Mechanistic studies revealed that compounds 1 and 3 triggered paraptosis-like cell death through the accumulation of react-ive oxygen species(ROS),activation of ER stress,and stimulation of the MAPK signaling pathway.

Atherosclerosis(AS) is an important pathological feature of cardiovascular diseases such as myocardial infarction,stroke and other highly fatal diseases. Phlegm and dampness are considered to be an important pathogenesis of AS,which is difficult to heal and can cause complications. The establishment of an animal model with AS and phlegm-dampness syndrome,which could reflect the features of traditional Chinese medicine(TCM),and objective evaluation system are an important element of modern integrated TCM and western medicine research on cardiovascular diseases. It is of great significance for TCM to prevent and treat cardiovascular diseases. This article summarizes the scientific connotations of traditional Chinese and western medicine for AS and phlegm-dampness syndrome,comprehensively summarizes the current status of construction and evaluation in experimental animal model,analyzes the problems of current model,and discusses the factors of model construction and evaluation. Our aim is to establish normalized and standardized animal model with AS of phlegm-dampness syndrome.

Objective:To observe and analyze the morphological characteristic of bone marrow and peripheral blood in patients diagnosed with de novo acute leukemia.Methods:From October 1, 2015 to December 31, 2021, 1151 patients aged 47 (26, 62) years, consisting of 602 males and 549 females with newly diagnosed acute leukemia in the Department of Hematology, Affiliated Hospital of Xuzhou Medical University, were collected to preform the morphological analysis in bone marrow and peripheral blood smears. Based on the comprehensive diagnosis results of morphology, immunology, cytogenetics, and molecular biology, comparison between acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL), AML with RUNX1-RUNXITI gene, AML with CBFβ/MYH11 gene, acute promyelocytic leukemia (APL) with PML/RARA gene, AML with NPM1 gene, the rest of the AML, Ph+ALL and Ph-ALL were performed by Chi-square test along with analysis of the differences in the ratio of wood bundle cells, pseudo-Chediak-Higashi (PCH) inclusions, cytoplasmic small particles, nuclear notches, leukemia cells with cup-like changes (cup cells); as well as the differences in the micromeganuclei, early immature granulocytes, plasma cells, high eosinophils and other accompanying cells and the distribution of "grape-like" aggregation. Finally, the morphological characteristics of acute leukemia cells, the appearance and arrangement of accompanying cells were summarized.Results:Between AML and ALL, there were statistically significant differences in cytoplasmic Auer bodies[(45.5%, 0%), χ 2=211.400, P<0.01], PCH inclusion bodies[(28.9%, 0%), χ 2=114.100, P<0.01], cytoplasmic fine particles[(20.7%, 2.9%), χ 2=53.798, P<0.01], nuclear notches[(0.7%, 6.1%), χ 2=30.906, P<0.01], and goblet cells[(4.9%, 0.3%), χ 2=13.495, P<0.01], micromegakaryus [(22.4%, 0.3%), χ 2=80.398, P<0.01], plasma cells[(87.6%, 10.6%), χ 2=604.241, P<0.01], hyperacidophils[(15.3%, 1.0%), χ 2=46.116, P<0.01] showed significant differences in the "grape-like" aggregation distribution. In AML with RUNX1-RUNXITI gene, the changes of vacuoles and PCH inclusion bodies are more obvious; in AML with CBFβ/MYH11 gene, the increase of hypereosinophils is more obvious; in APL with PML/RARA gene, the increase of woodbundle is more obvious. The morphology of nuclei chromatin, nucleolus, and vacuoles were also different among the groups. Comparison between Ph+ALL and Ph-ALL showed that Ph+ALL was more prone to develop early immature granulocytes and plasma cells (all P<0.05). Conclusion:There are significant differences between AML and ALL in the characteristics of leukemia cells, the regularity of accompanying cells, and the aggregation and distribution patterns. The subtypes of AML with specific genetic abnormalities have their own characteristics in the appearance of vacuoles, PCH inclusions, hypereosinophils, woodbundle cells, and goblet cells. Ph+ALL is more prone to present early immature granulocytes and plasma cells.

Objective:To investigate the effect of different negative pressure level on drain volume after augmentation mammoplasty through inframammary fold incision, and try to put forward the appropriate negative pressure level for the best prognosis of patients.Methods:This was a randomized controlled clinical study. Patients who underwent prosthetic augmentation mammoplasty through inframammary fold incision in the Medical Beauty Center of the First Affiliated Hospital of Zhengzhou University from January 2019 to August 2021 were selected as the study subjects. Patients were divided into 4 groups by random number table method and different levels of negative pressure drainage were applied: 600 ml adjustable negative pressure drain bottle was used uniformly after operation by -80--85 kPa group, -40--60 kPa group, and -15--30 kPa group. In 0--5.2 kPa group, 300 ml drain drum was applied after operation. The criteria for drain removal was that the drain volume within 24 hours was less than 10 ml and the drainage fluid was clear. Daily drain volume, duration of drain placement, total drain volume, acceptance of the drain device and postoperative complications were recorded in the four groups. The corresponding indexes of each group were statistically analyzed by SPSS 21.0. Measurement data were expressed as Mean±SD. One-way analysis of variance was used for comparison between groups, and LSD- t test was used for pair comparison between groups. P<0.05 was considered statistically significant. Results:A total of 80 patients were included, 20 in each group. Inter-group equilibrium analysis: there was no significant difference in age, body mass index, distance from midclavicular point to nipple, distance from inferior mammary fold to nipple, and breast tissue thickness among 4 groups ( P>0.05). Evaluation of curative effect between groups: on the first and second day after operation, there was no significant difference in drain volume between -80--85 kPa group and -40--60 kPa group ( P>0.05), but there was significant difference among other groups ( P<0.05). There was significant difference in drain volume on the third day after operation, total drain volume and duration of drain placement between the four groups ( P<0.05). The lower the negative pressure level was, the less drain volume on the third day after surgery and the less total drain volume, and the shorter duration of drain placement. The duration of drain placement of the four groups were (5.6±0.7) d (-80--85 kPa group), (4.8±0.5) d (-40--60 kPa group), (4.0±0.5) d (-15--30 kPa group), and (3.2±0.4) d (0--5.2 kPa group), respectively. Safety evaluation: the complication rate of -80--85 kPa group, -40--60 kPa group, -15--30 kPa group and 0--5.2 kPa group were 2.5% (1/40), 2.5% (1/40), 0(0/40) and 15.0% (6/40), respectively. The complication rate of 0--5.2 kPa group was the highest. Investigation on the acceptance of the drainage device (no impact/dissatisfaction): 75 patients expressed dissatisfaction, with a dissatisfaction rate of 93.75%(75/80). Conclusion:In augmentation mammoplasty through inferior fold incision low negative pressure provides less drain volume, shorter drain placement. Negative pressure between -15 to -30 kPa is optimal.
