Traditional Chinese medicine （TCM）， through its multi-target and systematic regulatory effects， has demonstrated unique advantages in the treatment of gastric precancerous lesions （GPL）. At present， TCM theoretical research on GPL is mainly reflected in three aspects， the integration of macroscopic syndrome differentiation， the inflammation-carcinoma transformation mechanism， as well as the systematization and scientization of theoretical inheritance from famous TCM practitioners. High-quality evidence-based research findings serve as the foundation for clinical practice guidelines on GPL， and TCM has gained international academic recognition in the field of GPL prevention and treatment. Research on TCM mechanisms has yielded a series of important outcomes in the aspects of signaling pathways， gene expression regulation， cellular epigenetics， histone modification， and intestinal microecology. It is proposed that future research on GPL should focus on four key directions， establishing multi-omics data， exploring targeted intervention strategies on key regulatory nodes， advancing the standardization process of integrated traditional Chinese and western medicine prevention and treatment technologies， and constructing stratified screening and intervention platforms. The in-depth integration of TCM microcosmic mechanism of action with its macroscopic syndrome differentiation and treatment system， coupled with interdisciplinary research， will provide valuable references for the clinical treatment and scientific research of GPL.

OBJECTIVE To assess the safety profile of sintilimab in combination with chemotherapy for the treatment of cholangiocarcinoma. METHODS The data of patients with cholangiocarcinoma from January 1st， 2021 to December 31st， 2022 were collected and divided into control group （29 cases） and observation group （18 cases） based on different medication regimens. Patients in the control group were treated with Gemcitabine hydrochloride for injection+Cisplatin for injection or Oxaliplatin for injection， the observation group was treated with Sintilimab injection based on the control group. Patients in each group underwent blood routine， liver and kidney function， biochemical and other examinations before and after each treatment cycle to observe the occurrence of adverse drug reactions. The correlation of adverse drug reactions with drugs was evaluated with Naranjo’s scale. RESULTS The correlation between blood toxicity and drug use was deemed “probable” in both groups； however， the observation group exhibited a significantly higher score， indicating a stronger correlation. In the control group， hepatotoxic reactions were classified as “suspicious” whereas in the observation group， they were categorized as “probable”. The correlation of gastrointestinal symptoms between the two groups was considered “possible”. Systemic symptoms， skin toxicity， musculoskeletal toxicity， endocrine toxicity and renal toxicity were all classified as having a “suspicious” correlation with drug use. The total incidence of blood toxicity in the observation group was significantly higher than control group （P＝0.014）. There was no statistically significant difference in the total incidences of hepatotoxic， gastrointestinal symptoms， systemic symptoms， skin toxicity， musculoskeletal toxicity， endocrine toxicity， renal toxicity， or the incidence of grade 3 or higher blood toxicity， hepatotoxic between the two groups （P＞0.05）. For the patients experiencing adverse drug reactions， the symptoms were alleviated following drug discontinuation or symptomatic supportive treatment. No fatalities occurred during the treatment period. CONCLUSIONS Sintilimab combined with chemotherapy may significantly increase the risk of blood toxicity in patients with cholangiocarcinoma， especially thrombocytopenia， but the adverse reactions are within a controllable range， and the overall safety is good.

Enamel demineralization, the formation of white spot lesions, is a common issue in clinical orthodontic treatment. The appearance of white spot lesions not only affects the texture and health of dental hard tissues but also impacts the health and aesthetics of teeth after orthodontic treatment. The prevention, diagnosis, and treatment of white spot lesions that occur throughout the orthodontic treatment process involve multiple dental specialties. This expert consensus will focus on providing guiding opinions on the management and prevention of white spot lesions during orthodontic treatment, advocating for proactive prevention, early detection, timely treatment, scientific follow-up, and multidisciplinary management of white spot lesions throughout the orthodontic process, thereby maintaining the dental health of patients during orthodontic treatment.

Objective:To investigate the anti-inflammatory effects of Duhuo Jisheng Decoction on type Ⅱ collagen emulsion induced arthritis (CIA) model rats from the perspective of M1/M2 macrophage balance mediated development of rheumatoid arthritis.Methods:SD rats were divided into a normal group of 8 and a model group of 32. The CIA model was established using collagen antibody induction method for modeling. The successfully modeled rats were randomly divided into model group, methotrexate group, and Duhuo Jisheng Decoction medium- and high-dosage groups using a random number table method, with 8 rats in each group. Duhuo Jisheng Decoction medium- and high-dosage groups were orally administered with Duhuo Jisheng Decoction at dosages of 13.5 and 27.0 g/kg, once a day; methotrexate group received oral administration of 2.0 mg/kg methotrexate twice a week; normal group and model group were given equal volumes of physiological saline by gavage once a day for 28 consecutive days. The general condition of each group of rats was observed, the degree of swelling in the right knee joint was measured, and the arthritis index was scored; HE was used to observe pathological changes in synovial tissue; immunofluorescence was used to detect the expressions of markers CD86 and CD206 in synovial macrophages; Real time PCR was used to detect the mRNA levels of IL-6, TNF-α, IL-10, and TGF-β in synovial tissue.Results:Duhuo Jisheng Decoction could significantly improve the mental state of the rats and reduced the swelling of the knee joints and the arthritis index ( P<0.01). Compared with the model group, the cartilage structure in the knees of rats in the Duhuo Jisheng Decoction group was more intact and clearer. The expression level of the M1 macrophage marker CD86 significantly decreased, and the expression level of the M2 macrophage marker CD206 significantly increased; the mRNA expressions of IL-6 and TNF-α in the knee joint synovial tissue were significantly reduced ( P<0.05), while IL-10 and TGF-β levels significantly increased ( P<0.05). Conclusion:Duhuo Jisheng Decoction may promote macrophage polarization towards M2 type, thereby achieving M1/M2 macrophage balance, alleviating inflammatory response in rheumatoid arthritis rats, and exerting therapeutic effects on rheumatoid arthritis.

Lung cancer remains one of the leading cause of global cancer-related mortality, posing a significant burden of disease. Tobacco exposure stands as the foremost risk factor for lung cancer. Since the 1960, global efforts have gradually been implemented to control tobacco exposure, consequently reducing tobacco exposure levels within populations. This shift in exposure levels may have altered the epidemiological characteristics of lung cancer globally. This study aims to describe global lung cancer incidence data across five dimensions: age, gender, region, stage at diagnosis, and survival status, using global cancer registry data and relevant research findings. The objective is to elucidate the current epidemiological features of lung cancer worldwide, providing a scientific basis for lung cancer prevention and control. Furthermore, this study offers corresponding measures and recommendations for lung cancer prevention and control, aligning with the three-tiered cancer prevention strategy. Findings indicate that the incidence and mortality burden of lung cancer is significantly higher among the elderly population (aged 65 years and above) compared to the working-age population (aged 15-64 years). The aged-standardized incidence rate of lung cancer remains higher in males than in females, but the overall aged-standardized incidence rate of lung cancer in males shows a declining trend, while that in females shows an increasing trend. Regions with high and very high human development index (HDI) exhibit a substantially higher incidence and mortality burden of lung cancer compared to regions with low and very low HDI. Japan ranks highest in the diagnosis of stage Ⅰ lung cancer, with a diagnosis rate of 38.6%. Its age-standardized 5-year net survival rate is relatively high at 32.9%. Despite improvements in the survival status of lung cancer in certain countries like China and Japan, the overall prognosis for lung cancer remains pessimistic. Given the current epidemiological characteristics of lung cancer, reinforcing tobacco control measures and reducing female-specific lung cancer risk factors stand as significant goals for primary prevention. Promoting low-dose computed tomography screening for high-risk population, minimizing false-positive rates in lung cancer screening, and promoting medical system reforms and standardized treatment constitute principal measures for secondary and tertiary lung cancer prevention, respectively.

Objective:To analyze the incidence, mortality, and survival status and trends of lung cancer in China.Methods:The data of incidence, mortality, disability-adjusted life year (DALY), and survival status and trends of lung cancer in China were collected from GLOBOCAN 2020, Global Burden of Disease Study in 2019 (GBD2019) databases, and the CONCORD-3 project report. Joinpoint 5.0 software was used to analyze the age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) of lung cancer in China from 1990 to 2019. Data management was conducted by using Excel 2016, and relevant graphical representations were generated using the ggplot2 package in software R 4.2.1.Results:In 2020, a total of 815 563 lung cancer cases were newly reported in China with the ASIR of 34.8/100 000, in which 539 181 cases were reported in men, with the ASIR of 47.8/100 000, and 276 382 cases were reported in women, with the ASIR of 22.8/100 000. A total of 714 699 lung cancer deaths were reported in 2020, with the ASMR of 30.2/100 000. Among these deaths, there were 471 546 deaths in men with the ASMR of 41.8/100 000, and 243 153 deaths in women with the ASMR of 19.7/100 000. From 1990 to 2019, the ASIR and ASMR of lung cancer in both men and women showed increasing trends ( P<0.05). However, from 2010 to 2019, the ASIR and ASMR of lung cancer in men showed decreasing trends, with annual percent of change (APC) of -0.17% (95% CI: -0.24% - -0.09%) and -0.69% (95% CI: -0.79% - -0.59%), respectively. The ASIR and ASMR of lung cancer in women showed increasing trends from 2016 to 2019, with APC of 3.33% (95% CI: 2.73% - 3.88%) and 2.61% (95% CI: 1.99% - 3.28%), respectively. The five-year net survival rate for lung cancer was 19.8% in China (95% CI:19.4% - 20.2%) from 2010 to 2014. Conclusions:The morbidity and mortality of lung cancer in China remain at high levels, the prognosis of lung cancer was poor, and the disease burden of lung cancer would become more serious in the context of population aging, so three-level prevention of lung cancer should be implemented to address this problem. In addition, attention should be paid to the increasing trends of ASIR and ASMR of lung cancer in women in recent years. Further investigation of risk factors and targeted prevention are needed to curb the rising trend in the incidence of lung cancer in women.
