Immunotherapy, including immune checkpoint inhibitors, tumor vaccine therapy, oncolytic virotherapy, and adoptive cell therapy, has made remarkably breakthroughs in the field of oncology. Immune checkpoint inhibitors, which block programmed death receptor 1 or programmed death ligand 1, have been included in the first-line clinical treatment for advanced solid tumors, such as non-small cell lung cancer and malignant melanoma. However, primary or secondary drug resistance in tumors severely limits the survival benefits for patients. Immune-related adverse reactions, such as pneumonia, hypothyroidism, hypophysitis, and myocarditis, also greatly affect the quality of life of patients. Fuzheng Jiedu Huayu is an important concept guiding the prevention and treatment of tumors with traditional Chinese medicine (TCM). It is also a curative principle and therapeutic TCM method to reduce the toxicity and enhance the efficacy of immunotherapy. This article summarizes the research progress of immunotherapy and discusses how TCM reduces the toxicity and enhances the efficacy of immunotherapy, hoping to provide a reference for the integrated treatment of tumors with TCM and immunotherapy.

To summarize the clinical experience of Professor LIU Shangyi in treating pruritus vulvae. It is believed that women have the physiological characteristics of liver and kidney as the root， and their pubic area is easily attacked by wind-dampness pathogenic qi， so the core mechanism of pruritus vulvae is proposed as wind-dampness accumulation and deficiency of liver and kidney. The core treatment method is to dispel wind-dampness and nourish the liver and kidneys， and modify the Danggui Decoction （当归饮子） to form a self-prescribed Yinyang Formula （阴痒方） as the basic prescription to treat pruritus vulvaen.

BACKGROUND: Cancer is a major public health concern, particularly among middle-aged and elderly populations, who are disproportionately affected by rising cancer incidence. Environmental pollution has been identified as a significant risk factor for cancer development. China's Carbon Emission Trading Policy (CETP), implemented in pilot regions since 2013, aims to reduce carbon emissions and improve air quality. This study evaluates the impact of CETP on pan-cancer incidence, with a focus on its effects on specific cancer types and vulnerable populations. METHODS: This quasi-natural experiment utilized data from the China Health and Retirement Longitudinal Study (CHARLS) and environmental data from the China National Environmental Monitoring Center (2011-2018). A staggered difference-in-differences (DID) model was employed to estimate the impact of CETP on cancer incidence. Robustness tests, including parallel trend tests, placebo analysis, and entropy balancing, validated the findings. Subgroup analyses were performed to assess the policy's heterogeneous effects based on gender, Body Mass Index (BMI), and smoking status. RESULTS: CETP implementation significantly reduced the incidence of six cancer types: endometrial, cervical, gastric, esophageal, breast, and lung cancers. Overall, pan-cancer incidence significantly declined post-policy implementation (CETP × POST: -47.200, 95% CI: [-61.103, -33.296], p < 0.001). The policy demonstrated stronger effects in highly polluted areas and among individuals with poorer mental health. Subgroup analysis revealed that females, individuals with lower BMI, and non-smokers experienced more substantial benefits. CONCLUSIONS CETP significantly reduces cancer incidence by improving environmental quality and influencing mental health, with particularly strong effects observed among high-risk populations. This study highlights the important role of environmental economic policies in mitigating cancer burden and promoting public health. Future research should further explore the long-term impacts of this policy and its applicability across different national and regional contexts.

Growth arrest DNA damage-inducible protein 45 β (GADD45B) has been reported to be a regulatory factor for active DNA demethylation and is implicated in the modulation of synaptic plasticity and chronic stress-related psychopathological processes. However, its precise role and mechanism of action in stress susceptibility remain elusive. In this study, we found a significant reduction in GADD45B expression specifically in the ventral, but not the dorsal hippocampal CA1 (dCA1) of stress-susceptible mice. Furthermore, we demonstrated that GADD45B negatively regulates susceptibility to social stress and NMDA receptor-dependent long-term potentiation (LTP) in the ventral hippocampal CA1 (vCA1). Importantly, through pharmacological inhibition using the NMDA receptor antagonist MK801, we provided further evidence supporting the hypothesis that GADD45B potentially modulates susceptibility to social stress by influencing NMDA receptor-mediated LTP. Collectively, these results suggested that modulation of NMDA receptor-mediated synaptic plasticity is a pivotal mechanism underlying the regulation of susceptibility to social stress by GADD45B.

Objective To analyze the disease burden of early-onset colorectal cancer (EOCRC) at the global, regional, and national levels from 1990 to 2021, and to predict the disease burden trend from 2022 to 2026. Methods Based on the Global Burden of Disease (GBD) database, the incidence, mortality, and disability-adjusted life year (DALY) rate of EOCRC across 204 countries and regions from 1990 to 2021 were obtained. The time trends of these indicators were assessed by calculating the estimated annual percentage change (EAPC), and the contributions of ten risk factors to the EOCRC burden were analyzed. The autoregressive integrated moving average (ARIMA) model was used to predict the disease burden from 2022 to 2026. Results From 1990 to 2021, the number of new global EOCRC cases increased from 107 310 to 211 890, with the incidence rising from 3.96 to 5.37 per 100 000 people. In 2021, global EOCRC incidence, mortality, and DALY rate increased with age; males had higher rates than females in terms of incidence, mortality, and DALY rate in all age groups. In 2021, East Asia had the highest number of new cases, deaths, and DALY. From 1990 to 2021, the global EAPC for incidence rate was 0.96%, and death rate was –0.38%. ARIMA model indicated that from 2022 to 2026, the global incidence of EOCRC would continue to rise, while mortality and DALY rate would be expected to decline. Conclusions The disease burden of EOCRC has significantly increased globally from 1990 to 2021, with notable regional, age, and sex differences. By 2026, the mortality and DALY rate of EOCRC will decline, while the incidence is expected to further increase, highlighting the urgency of taking active measures to address the growing trend of EOCRC.

Objective To study the mechanism of Sanhuang Decotion in the treatment of ulcerative colitis(UC)under Candida albicans colonization in mice based on Dectin-1-Syk-CARD9 signaling pathway.Methods Mice model of UC with fungal colonization were established with dextran sodium sulfate free drinking and C.albicans intragastric administration.Mice were divided into normal control group,model group,sulfasalazine group,fluconazole group,and Sanhuang Decotion low-and high-dosage groups,and receive corresponding drug interventions.General state of mice were observed,and the disease activity index(DAI)score of mice were calculated.The load of C.albicans in intestine was detected,the length of the colon was measured,and pathological scoring of the colon tissue was performed.The ultrastructural changes of colon epithelium were observed under transmission electron microscopy.The contents of TNF-α,IL-6 and IL-12 in serum and colon tissues were detected by ELISA.The mRNA and protein expression of Dectin-1,Syk,CARD9,NF-κBp65 and inflammation factors in intestinal epithelial cells and colon tissues were detected by qPCR,Western blot and immunohistochemistry.Results Compared with the normal control group,the model group mice showed reduced activity,decreased food intake,accompanied by loose stools,significantly increased DAI score,increased load of C.albicans in the intestine,shortened colon length,and increased histopathological score,with widening of gap between colon epithelial cells,cytoplasmic dissolution,mitochondrial swelling;TNF-α,IL-6 and IL-12 in serum and colon tissue increased,the expressions of Dectin-1 and CARD9 mRNA and protein in colon epithelial cells increased,p-Syk,p-NF-κBp65,CARD9,TNF-α,IL-1β,IL-6 protein expression in colon tissue increased(P<0.01,P<0.05).Compared with the model group,the Sanhuang Decotion high-dosage group mice showed a significant decrease in DAI score,decreased intestinal C.albicans load,increased colon length,decreased histopathological score,more complete and orderly arrangement of microvilli in colon epithelial cells,mild mitochondrial swelling,TNF-α,IL-6 and IL-12 in serum and colon tissue decreased,and the mRNA and protein expression of Dectin-1 and CARD9 in colon tissue increased,the expression of p-Syk,p-NF-κBp65,CARD9,TNF-α,IL-1β,IL-6 protein in colon tissue decreased(P<0.01,P<0.05).Conclusion Sanhuang Decotion may exert an anti C.albicans colonization UC effect by inhibiting the Dectin-1-Syk-CARD9 signaling pathway and reducing the release of inflammatory factors.

Objective:To analyze the clinical efficacy and prognostic factors of comprehensive treatment for atypical teratoid / rhabdomyoma tumor (AT/RT).Methods:Clinical data of children diagnosed with AT/RT who underwent radiotherapy in Department of Oncology of Xinhua Hospital affiliated to Shanghai Jiao Tong University School of Medicine from November 2012 to September 2022 were retrospectively analyzed. Pearson Chi-square test or continuous-corrected Chi-square test or Fisher's exact probability method were used for inter-group comparison of categorical variables. Independent sample t-test or Wilcoxon rank-sum test were used for inter-group comparison of continuous variables. Kaplan-Meier method was used to calculate the 1-year and 2-year overall survival (OS) rate and progression free survival (PFS) rate. Univariate and multivariate Cox regression analyses were employed to determine relevant prognostic factors. Results:A total of 45 patients were included, with a male/female ratio of 1.65:1, including 27 children aged ≥3 years old. All patients received surgery and radiotherapy in which 39 patients received chemotherapy, 41 craniospinal irradiation (CSI), and 4 whole brain or focal radiation therapy. The median follow-up was 28 (13.5, 49) months. A total of 14 patients died after comprehensive treatment. The 1-year OS rate was 80.0% and the PFS rate was 71.1%. The 2-year OS rate was 75.5% and the PFS rate was 65.7%. Survival prognostic analysis showed negative imaging assessment after radiotherapy ( HR=0.087, 95% CI: 0.011-0.697, P=0.022) was a favorable factor for PFS. The primary tumor<4.8 cm ( HR=0.221, 95% CI: 0.052-0.935, P=0.040) and CSI ( HR=0.085, 95% CI: 0.011-0.651, P=0.018) were favorable factors for OS. In subgroup analysis, CSI also improved OS in children aged ≥3 years ( HR=0.014, 95% CI: 0-0.470, P=0.017), but there was no significant difference in PFS. In children without cerebrospinal fluid dissemination, negative radiographic results after radiotherapy ( HR=0.066, 95% CI: 0.009-0.481, P=0.007; HR=0.076, 95% CI: 0.008-0.695, P=0.024, respectively) and CSI (HR=0.105, 95% CI: 0.012-0.937, P=0.044; HR=0.054, 95% CI: 0.005-0.629, P=0.020, respectively) were favorable factors for PFS and OS in children, and the primary tumor<4.8 cm also suggested a longer OS ( HR=0.094, 95% CI: 0.013-0.690, P=0.020). Conclusions:Comprehensive treatment including radiotherapy improves clinical prognosis of children with AT/RT. Our study shows that negative imaging results after radiotherapy are associated with PFS improvement. The primary tumor<4.8 cm and CSI are favorable factors for OS. CSI is also a significantly positive prognostic factor in children aged ≥3 years and those without cerebrospinal fluid dissemination.

Objective:In this retrospective study, the accuracy and outcomes of segmental Le Fort I surgery with the aid of 3D-printed surgical templates and occlusal splints and dental model surgery were evaluated.Methods:Clinical data of patients receiving segmental Le Fort I surgery in the Department of Orthognathic and Temporo-Mandibular Joint Surgery of West China Stomatological Hospital of Sichuan University from January 2014 to June 2019 were retrospectively analyzed. The accuracy of virtual surgical planning(VSP) and the difference between VSP and dental model surgery were evaluated by postoperative complications, color distance maps, and quantitative accuracy analysis.The amount of surgical displacement of the maxilla in the three-dimensional direction before and after surgery, the occurrence of postoperative complications and the patients'satisfaction survey were analyzed in both groups. Paired t-tests were used for the linear distance and angle between the preoperative design model and the final virtual surgery model in the digital surgery group. Independent samples t-test was used for each marker point’s preoperative and postoperative displacements in the three-dimensional direction between the digital surgery group and the dental model group. The proportion of postoperative complications in the 2 groups was tested using the Pearson chi-square test, and the difference was considered statistically significant at P<0.05. Results:There were 129 patients in the digital surgery group, 35 males and 94 females, aged (24.5±6.5) years, and 92 patients in the dental model surgery group, 28 males and 64 females, aged (27.7±5.4) years.The overall mean linear difference was 1.23±0.35 mm, and the overall mean angular difference was 2.48°±0.31°. The vertical displacement of U3R, U6L in the digital surgery group was (6.72±1.57)mm and (4.73±2.07)mm. The vertical displacement of U3R, U6L in the group of dental model surgery was (4.07±2.14)mm and (1.62±1.82)mm.The significant deviation difference in U3R-Y and U6L-Y between two groups could be detected. The complications in two groups showed a significant difference. Except for one case of root injury, there was no serious complication recorded in the digital surgery group. However, there were three cases of palatal fistulas, four cases of root injury and two cases of bone dehiscence in the dental model group. 94.5% of patients in the digital surgery group are satisfied with the surgical results, while 89.1% in the dental model group.Conclusion:Compared with dental model surgery, segmental Le Fort I surgery is highly accurate under the guidance of surgical templates and occlusal splint which has better postoperative results and effectively reduces the occurrence of surgical complications.

Objective:To analyze the association between zygomatic change and bone setback or resection and propose a quantitative guidance for L-shaped reduction malarplasty by linear regression analysis based on computed tomographic (CT) scan images.Methods:A retrospective observational study was conducted on patients who underwent L-shaped reduction malarplasty with mortice and tenon joint at the zygomatic arch in Department of Orthognathic and Temporomandibular Joint Surgery, West China Hospital of Stomatology, Sichuan University from January 2017 to September 2022. Bone setback and resection were performed in cases required a classical L-shaped osteoectomy with oblique bone resection (Group Ⅰ). Bone setback was performed in cases required a modified L-shaped osteotomy without bone resection (Group Ⅱ). Wound healing and the occurrence of complications were followed up after operation. The amount of bone setback and resection were calculated by using preoperative and postoperative CT scan images. The unilateral width changes of the anterior, middle, and posterior zygomatic regions(ΔZBP-MFP, ΔZMP-MFP, ΔZAP-MFP, respectively) as well as zygomatic protrusion change(Δzygomatic protrusion) were also evaluated. SPSS 20.0 software was used for statistical analysis. The measurement data was expressed as Mean±SD. Zygomatic width and protrusion change of the two groups was compared by independent t-test. Comparison of complication rates between the two groups was performed using the χ2 test. Correlation analysis using Pearson correlation coefficients was performed between bone resection or setback and zygomatic width or protrusion change. Linear regression analysis was also performed. Results:A total of 80 patients were enrolled. Group Ⅰ consisted of 40 patients [6 males and 34 females; aged (25.2±3.8) years, ranging from 19 to 33 years] who underwent a classical L-shaped osteotomy with both bone setback and resection, while Group Ⅱ consisted of 40 patients [10 males and 30 females; aged (26.0±3.0) years, ranging from 20 to 35 years] who underwent a modified L-shaped osteotomy with bone setback but without bone resection. All patients healed uneventfully during the follow-up period[(12.5±3.3) months, ranging from 5 to 20 months]. There was no significant difference in the incidence of complications such as infection, transient paresthesia, severe swelling and hematoma between the two groups ( P>0.05). No severe complications, such as facial asymmetry, sagging cheek, bone nonunion, were observed. All patients significantly improved facial contours. There was a statistically significant difference (all P<0.01) in ΔZBP-MFP [ (2.52±0.76) mm vs. (1.85±0.40) mm], ΔZMP-MFP [ (3.30±0.54) mm vs. (2.94±0.51) mm] and Δzygomatic protrusion [ (4.42±1.20) mm vs. (3.59±0.84) mm] between Group Ⅰ and Group Ⅱ. No statistical difference was found in ΔZAP-MFP ( P>0.05). Significant correlation was observed between the bone setback or resection and the changes of anterior, middle zygomatic width as well as protrusion in both the two groups ( r=0.60-0.92, all P<0.01), and the linear regression equation was established. The correlation between bone setback or resection and the posterior zygomatic width change was not significant ( P>0.05). Conclusion:There are linear correlations between the unilateral anterior, middle zygomatic width change, zygomatic protrusion change and the unilateral bone setback or resection. The linear regression equations can be used as a quantitative guidance for preoperative surgical planning.

Objective To establish normal reference values for left ventricular trabecular and papillary muscle mass(TPMM)in Chinese adults using MRI and to explore its impact factors.Methods A total of 168 healthy Chinese adults were retrospectively included,and compacted and total left ventricular myocardial mass(LVM)were measured using traditional and dedicated methods,respectively.TPMM was calculated from the difference between total and compacted LVM.Independent sample t-tests and analysis of variance were used to explore the differences in TPMM among genders and age groups,while multiple linear regression was used to explore the independent correlation between TPMM and age,gender,heart rate,systolic blood pressure(SBP),fasting blood glucose(FBG),and body mass index(BMI).Results TPMM for men was significantly larger than that for female(P<0.001).TPMM in the elderly group was significantly larger in female(P<0.05),but not in men.Multiple linear regression showed that BMI and SBP were both independently positively correlated with TPMM,and female and heart rate were independently negatively correlated with TPMM(P<0.05).Conclusion This study provides age-and gender-specific normal reference values for TPMM in Chinese adults.Gender,heart rate,BMI,and SBP are all independently associated with TPMM.
