The cellular and molecular components of the tumor immune microenvironment (TIME) and their information exchange processes significantly influence the trends of anti-tumor immunity. In recent years, numerous studies have begun to evaluate TIME in the context of previous cancer treatment strategies. This review will systematically summarize the compositional characteristics of TIME and, based on this foundation, explore the impact of current cancer therapies on the remodeling of TIME, aiming to provide new insights for the development of innovative immune combination therapies that can convert TIME into an anti-tumor profile.

Objective:To establish a method for detecting serum non-ceruloplasmin-bound copper (NCC) by immunoprecipitation-inductively coupled plasma mass spectrometry (IP-ICP-MS) and evaluate its clinical application.Methods:Methodological evaluation research. Immunoprecipitation was first used to separate serum ceruloplasmin, followed by detection of serum NCC levels using ICP-MS. Two levels of quality control serum were reconstituted to determine the limit of detection (LOD), limit of quantitation (LOQ), accuracy, and precision of the self-developed method. The serum samples of 131 healthy individuals (healthy group) and 69 first-time diagnosed Wilson′s disease (WD) patients(WD group) from November 2023 to June 2024 in the Affiliated Hospital of Institute of Neurology, Anhui University of Traditional Chinese Medicine were collected. Using self-developed method detected the serum NCC levels, established the healthy reference intervals, and NCC levels between the two groups were compared using the Mann-Whitney U test. Results:The calibration curve exhibited excellent lineary across the concentration range of 1.562 to 300.000 μg/L, as demonstrated by coefficient of determination ( R2) of 0.999. The self-developed NCC method exhibited that the LOD was 0.99 μg/L, the LOQ was 3.29 μg/L, the accuracy (spike and recovery experience) was 87.67%?106.27%, and the intra-batch and inter-batch imprecision expressed as coefficient of variation ( CV) was 2.8%?7.3%, and the healthy reference range was 34.31-71.79 μg/L. The serum NCC levels in the WD group were 102.39 (74.38, 144.04) μg/L, which was significantly higher than those in healthy group (51.45±10.34) μg/L ( Z=?7.967, P<0.01). Conclusions:The established IP-ICP-MS method for detecting serum NCC meets the required analytical performance criteria. It is simply operative, highly sensitive, and provides accurate and reliable results, which could be used for clinical detection.

By combing the physiological characteristics of wind and fire, the article makes it clear that wind and fire are evils, and external wind is easy to attack and even worse when it encounters fire; burnt and moving fire evils set off internal winds; and the incitement of each other can lead to the occurrence of palpitations. From the perspective of the theory of "wind and fire inciting each other", the clinical diagnosis and treatment of palpitation is discussed, which clarifies that there is an internal and external distinction between wind and fire, and there is an internal and external distinction between the real and the imaginary, which should be carefully distinguished in the diagnosis and treatment of palpitation. In the treatment, wind medicine can be skillfully applied to drive away the wind evil to calm the internal and external, and it is also necessary to clearly identify the source of the fire evil and properly choose the corresponding treatment for the fire evil in order to extinguish the burnt fire. As the positive qi exists and the evil will not dry up, we should not forget to take care of the heart in the treatment. An example of a medical case is attached in order to provide new ideas for the clinical treatment of palpitation.

Early distinction of bipolar disorder (BD) from major depressive disorder (MDD) is difficult since no tools are available to estimate the risk of BD. In this study, we aimed to develop and validate a model of oxidative stress injury for predicting BD. Data were collected from 1252 BD and 1359 MDD patients, including 64 MDD patients identified as converting to BD from 2009 through 2018. 30 variables from a randomly-selected subsample of 1827 (70%) patients were used to develop the model, including age, sex, oxidative stress markers (uric acid, bilirubin, albumin, and prealbumin), sex hormones, cytokines, thyroid and liver function, and glycolipid metabolism. Univariate analyses and the Least Absolute Shrinkage and Selection Operator were applied for data dimension reduction and variable selection. Multivariable logistic regression was used to construct a model for predicting bipolar disorder by oxidative stress biomarkers (BIOS) on a nomogram. Internal validation was assessed in the remaining 784 patients (30%), and independent external validation was done with data from 3797 matched patients from five other hospitals in China. 10 predictors, mainly oxidative stress markers, were shown on the nomogram. The BIOS model showed good discrimination in the training sample, with an AUC of 75.1% (95% CI: 72.9%-77.3%), sensitivity of 0.66, and specificity of 0.73. The discrimination was good both in internal validation (AUC 72.1%, 68.6%-75.6%) and external validation (AUC 65.7%, 63.9%-67.5%). In this study, we developed a nomogram centered on oxidative stress injury, which could help in the individualized prediction of BD. For better real-world practice, a set of measurements, especially on oxidative stress markers, should be emphasized using big data in psychiatry.

Objective:To determine the correlation between the diabetes mellitus control and periodontitis.Methods:This study was a cross-sectional survey using stratified system sampling model design. The target population was the patients with diabetes investigated from May to July 2018 in Huangpu District of Shanghai. In the present study, severe periodontitis was defined as at least at two sites in different quadrants with probing depth (PD)≥6 mm and clinical attachment loss (CAL)≥ 5 mm. Edentulous induced by periodontitis were also classified as severe periodontitis and the others were classified as non-severe periodontitis subjects. Diabetes control levels were divided into the following three groups: poorly controlled group [glycated hemoglobin (HbA1c)>7.5% and fasting blood glucose (FPG)>7.0 mmol/L], well controlled group (6.5%≤HbA1c≤7.5% or 6.1 mmol/L≤FPG≤7.0 mmol/L) and ideally controlled group (HbA1c<6.5% and FPG<6.1 mmol/L). SPSS 25.0 was used for statistical analysis. Chi square test was used for demographic data and frequency distribution, α=0.05, two-sided test. Ordinal regression model was used for PD and diabetes control status to balance confounding factors (including age, gender, education and smoking status). After matching the propensity scores between severe periodontitis group and non-severe periodontitis group, logistic regression analysis was used to analyze the level of diabetes control and periodontitis.Results:A total of 5 220 adults over the age of 18 with a medical history of diabetes participated in the survey, of which 3 064 subjects with diabetes mellitus type 2 (T2DM) who were given both oral and laboratory examinations and were included in this study. Statistics showed that the prevalence of moderate and severe periodontitis was 10.57% (324/3 064). In the severe periodontitis group, 79.01% (256/324) of the subjects were over 65 years old, 55.56% (180/324) were male, 58.33% (189/324) had lower education level than high school level, and 21.91% (71/324) were smokers, which were significantly higher than those in the non-severe periodontitis group ( P<0.01). In different T2DM status groups, the percentage of severe periodontitis increased with the aggravation of T2DM status. In severe periodontitis group, the proportion of patients with poor glycemic control was higher. T2DM patients with poor glycemic control accounted for 68.52% (222/324) in severe periodontitis group, which was significantly higher than the proportion of non-severe periodontitis group of 60.99% (1 671/2 740) ( P<0.05). The regression coefficient of PD was 0.191, and PD had a significant negative effect on the level of blood glucose ( P<0.01). There was a significant positive correlation between diabetes glycemic control and severe periodontitis ( OR=2.800, P<0.05). Conclusions:In Huangpu District of Shanghai, among T2DM patients, the age of severe periodontitis group was higher than that of non-severe periodontitis group, most of them were male, with lower education level and higher proportion of smoking. The severity of diabetes was related to periodontitis and the proportion of severe periodontitis was higher in patients with poor glycemic control.

Objective:To investigate the clinicopathological features and differential diagnosis of metastatic tumors in the lung.Methods:The clinicopathological data of 226 metastatic tumors in the lung were collected at Peking Union Medical College Hospital, Chinese Academy of Medical Science & Peking Union Medical College, from January 2014 to December 2018, and the pathomorphological characteristics were analyzed.Results:There were 84 males and 142 females, with an age range from 13 to 77 years. There were 122 patients with multiple pulmonary nodules and 104 patients with solitary pulmonary nodule. The tumors of the highest frequencies were colorectal cancer ( n=59), followed by trophoblast tumor ( n=44), kidney cancer ( n=31), breast cancer ( n=20), cervix cancer ( n=14), and urinary urothelium cancer ( n=8). The time from the diagnosis of primary tumors to metastasis and the status of surgical treatment varied by tumor origin. The morphology of metastatic lung tumors overlapped with that of the primary tumors to some extent. The relative specific morphological characteristics and the presence of carcinoma in situ surrounding the tumors should be carefully searched for to confirm the tumor origin. The metastatic tumors of the lung had morphological characteristics, immunohistochemical TTF1 (-) and tumor of various sources, while the primary tumor differentiation had relatively specific antibodies: colorectal cancer CK20 (+), CDX2 (+), CK7 (-); malignant trophoblastic tumor, HCG (+); renal clear cell carcinoma CD10 (+), vimentin (+), CK7 (-); breast cancer, GATA3 and ER (+); cervical cancer, p16 (+); urothelial carcinoma, CK20, p63 and GATA3 (+). Conclusions:There is overlap between pulmonary metastatic tumor and primary tumor in morphology. Therefore, the diagnosis should be made by combining clinical history, pathological morphology and immunophenotypic characteristics.
