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.

Limited-stage small cell lung cancer(SCLC)is a highly malignant and rapidly progressing neuroendocrine tumor,while uremia is a complication of the end-stage of chronic renal failure.The patients with SCLC complicated with uremia have poor treatment tolerance,limited options for anti-tumor treatment regimens,and great difficulty in diagnosis and treatment.This study analyzed one case of a 69-year-old male patient with limited-stage SCLC complicated with uremia(with a history of regular hemodialysis,3 times per week),to discuss his first-line treatment regimen,efficacy,and the impact of hemodialysis on the plasma concentrations of the anti-tumor drugs,and reviewed the relevant literature to provide a reference for the treatment of similar patients.The patient was admitted to the hospital due to"cough and hemoptysis for half a month"and was diagnosed with limited-stage SCLC stage ⅢA(T2aN2M0)by computed tomography(CT)and lung puncture biopsy.After discussion by the multi-disciplinary treatment(MDT)team,the patient received 6 cycles of Etoposide(VP-16)+carboplatin chemotherapy combined with adebrelimab immunotherapy,followed by sequential adebrelimab maintenance therapy.The efficacy was evaluated as partial response(PR)and the response is ongoing.During the treatment,level 4 hemoglobin decrease,level 3 neutropenia,and level 2 leukopenia occurred,which were alleviated after symptomatic treatment.The blood concentration monitoring results showed that the plasma concentrations of etoposide and carboplatin increased rapidly during drug infusion,and gradually decreased after the end of infusion.Hemodialysis could rapidly reduce the plasma concentration of carboplatin,but had no significant effect on the plasma concentration of etoposide.Therefore,the immunotherapy combined with reduced-dose chemotherapy regimen is safe and effective for this type of patient.Plasma drug concentration monitoring can be used to observe drug metabolism,but the optimal monitoring time points and clinical value need further study and validation.

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.

Objective:To evaluate the efficacy of cerebral-placental-uterine ratio(CPUR)in predicting late-on-set fetal growth restriction(FGR).Methods:From May 2020 to May 2021,1255 women with singleton pregnancy who underwent prenatal examinations at the University of Hong Kong Shenzhen Hospital were selected for fetal growth and Doppler measurements at 35-37 +6 weeks of gestation.Pregnant women with birth weight of newbo-rns＜the 10th percentile were the FGR group.The pulsatility index(PI)of uterine artery(UtA),umbilical artery(UA)and fetal middle cerebral artery(MCA)were analyzed separately and in combination.ROC curve was used to analyze the cerebral-placental-uterine ratio(CPUR),cerebral-placental ratio(CPR),cerebral-uterine ratio(C-UtA)for predicting late-onset FGR;and to evaluate the sensitivity,positive and negative predictive value and of CPUR in the prediction of late-onset FGR.Results:The area under the curve(AUC)of CPUR,CPR,C-UtA and mean UtA-PI for FGR grope were 0.88,0.86,0.84 and 0.72.Under certain cut-off values and 87% specificity,the specificity of CPUR,CPR,C-UtA and mean UtA-Pifor predicting FGR group was 43.2%,46.6%,39.8% and 23.9%,respectively.The positive predictive values of CPUR,CPR,C-UtA and mean UtA-PI,UA-PI for predicting FGR group were 90.5%,71.9%,83.3%,63.6%and 5.2%,respectively.Conclusions:CPUR is more effective in predicting late onset FGR than CPR,C-UtA and mean UtA-PI.It can effectively increase the detection rate of fetal growth restrictionand reduce the FGR risk.

Objective:To investigate the underlying neuroimaging mechanism of migraine without aura (MwoA) by using methods of voxel-based morphometry (VBM) and resting-state functional connectivity (FC).Methods:Twenty-five MwoA patients admitted to Department of Neurology, the Second Affiliated Hospital of Xuzhou Medical University from September 2020 to June 2023 were recruited as MwoA group, and 22 volunteers were recruited as healthy control (HC) group. Demographic, clinical characteristics, scores of Hamilton Anxiety Scale (HAMA), Hamilton Depression Rating Scale (HAMD) and Montreal Cognitive Assessment (MoCA) of all subjects were collected; MwoA patients also received Migraine Disability Assessment Questionnaire, Headache Impact Test-6 and headache Visual Analogue Scale assessments. All subjects underwent high-resolution 3D-T 1 and resting-state functional magnetic resonance imaging scanning. The SPM12 software was used to compare the difference in gray matter volume (GMV) between the 2 groups by VBM method. The GRETNA software was adopted to calculate the whole brain FC with anatomical automatic labeling 90 as the regions of interest, and the difference in FC between the 2 groups was statistically analyzed by two-sample t-test. Pearson partial correlation was used to analyze the correlation between brain GMV and FC changes and clinical features and scale scores of MwoA patients. Results:There existed no statistically significant difference between the 2 groups in age, gender, education, scores of HAMA, HAMD and MoCA (all P>0.05). Migraine Disability Assessment Questionnaire, Headache Impact Test-6 and headache Visua Analogue Scale scores of MwoA patients were (8.86±4.55), (50.27±6.35) and (6.68±1.73). Compared with the HC group, GMV was significantly decreased in the right superior frontal gyrus (SFG), right cingulate gyrus (CG) and left thalamus in the MwoA group ( P<0.05, false discovery rate corrected). In addition, the MwoA group showed decreased FC between left thalamus and right cuneus, left lingual gyrus (LG) and bilateral precuneus; decreased FC between right thalamus and right cuneus, right LG and right precuneus; decreased FC between right cuneus and left precuneus and right SFG; decreased FC between left LG and bilateral precuneus, decreased FC between right LG and right precuneus and left SFG; decreased FC between left precuneus and bilateral SFG, and between right precuneus and right SFG (edge P<0.001, component P<0.05, network-based statistics correction, interation=2 000). In MwoA patients, the FC (z-value) between left thalamus and right cuneus was negatively correlated with the duration of disease ( r=-0.530, P=0.011). Conclusions:MwoA patients showed decreased GMV in right SFG, CG and left thalamus. In MwoA patients, FC between thalamus and visual network (VN) and default mode network (DMN) was significantly decreased, and FC among VN, DMN and executive control network was significantly decreased. These changes in brain structure and function may be an adaptive change in the central sensitivity and responsiveness to pain stimuli, and may be an important neuroimaging mechanism of MwoA.
