ABSTRACT
Reflux esophagitis is an inflammatory disease of esophageal mucosa damage caused by the reflux of gastric contents into the esophagus. Its incidence is on the rise， and it has become an important precancerous disease of esophageal cancer. Studies have shown that the continuous inflammatory response stimulates the esophageal mucosa， causing abnormal proliferation of esophageal epithelial cells and damage to esophageal mucosal tissue， which eventually leads to the occurrence of heterogeneous hyperplasia and even carcinogenesis. The nuclear transcription factor-kappa B （NF-κB） signaling pathway is one of the most classical inflammatory and cancer signaling pathways. It has been found that abnormal activation of the NF-κB signaling pathway is crucial to the development and prognosis of reflux esophagitis and esophageal cancer. It is widely involved in the proliferation， autophagy， apoptosis， and inflammatory response of esophageal epithelial cells and tumor cells， accelerating the transformation of reflux esophagitis to esophageal cancer and making it a potential target for the treatment of reflux esophagitis and esophageal cancer. Currently， there is no specific treatment for reflux esophagitis and esophageal cancer， and large side effects often appear. Therefore， finding a promising and safe drug remains a top priority. In recent years， traditional Chinese medicine scholars have conducted a lot of research on NF-κB signaling pathway， and the results indicate that NF-κB signaling pathway is an important potential target for traditional Chinese medicine to prevent and treat reflux esophagitis and esophageal cancer， but there is a lack of comprehensive and systematic elaboration. Therefore， this paper summarized the relevant studies in recent years， analyzed the relationship among NF-κB signaling pathway， reflux esophagitis， esophageal cancer， and transformation from inflammation to cancer， and reviewed the research literature on the regulation of the NF-κB signaling pathway in traditional Chinese medicine to prevent and treat reflux esophagitis and esophageal cancer， so as to provide new ideas for the prevention and treatment of reflux esophagitis and esophageal cancer.
ABSTRACT
Peribiliary glands (PBG) is a kind of microscopic structure around the intra-hepatic bile ducts and extrahepatic bile ducts. PBG not only participates in maintaining the normal physiological function of biliary epithelial tissue, but also plays an important role in its damage and repair process. Biliary tree stem/progenitor cells in PBG are important cell sources of biliary epithelial regeneration and repair. PBG and the surrounding peribiliary vascular plexus are key influencing factors for the occurrence of ischemic-type biliary lesions (ITBL) after liver transplantation. Based on relevant literatures and clinical practice, the authors summarize the function of PBG as well as its relationship with ITBL.
ABSTRACT
Objective:To evaluate the diagnostic value and safety of transbronchial lung biopsy and bronchoalveolar lavage (BAL) in pulmonary complications in patients with hematological tumors.Methods:A retrospective analysis was performed on 68 patients with hematological tumors combined with lung lesions from The University of Hong Kong-Shenzhen Hospital and The Third People's Hospital of Shenzhen from May 2016 to May 2022, including 37 males, 31 females, with a median age of 56 years (age range 21-90 years), among which 20 patients were >65 years old. Diagnostic fiberoptic bronchoscopy was performed with signs including fever, cough, hypoxemia, hemoptysis, unexplained dyspnea, and imaging changes. Patients with pulmonary masses were evaluated for transbronchial lung biopsy, including inner and outer leaf mass and high-density shadow of lung leaves, pathological and special staining of biopsy tissue (Grocott staining), BAL acquisition of bronchoalveolar lavage fluid (BALF) for microbiological smear/culture, cytomegalovirus, Pneumocystis jirovecii and Mycobacterium tuberculosis (TB) smear, TB DNA, TB and fungal culture. Etiological analysis of pulmonary complications and observation of the complications associated with fiberoptic bronchoscopy in patients with hematological tumors were conducted. Results:BALF test was performed in all patients after bronchoscopy, bronchoscopic lung tissue biopsy was performed in 46 cases. The total number of confirmed pathogenic infections was 40, including 12 cases of fungal infections, 9 cases of bacterial infections (2 cases each of E. faecalis and Pseudomonas aeruginosa, 1 case of Staphylococcus aureus, 1 case of Klebsiella pneumoniae, 1 case of E. coli, 1 case of coagulase-negative Staphylococcus, and 1 case of Streptococcus mitis), 9 cases of viral infection (5 cases of cytomegalovirus, 3 cases of parainfluenza virus type Ⅲ, and 1 case of respiratory syncytial virus), 4 confirmed cases of Pneumocystis jirovecii pneumonia, 3 cases of suspected mixed infection of Pneumocystis jirovecii and fungi, 1 case of Cryptococcus, 2 cases of suspected TB infection. No pathogenic organisms were found in 28 cases, including 6 cases of mechanized pneumonia, 6 cases associated with a history of hematological tumors, and 16 cases of other unidentified pathogens. All patients did not experience death or other serious complications caused by bronchoscopy complications. Conclusion:Pulmonary complications are common in patients with hematological tumors, and the application of transbronchial lung biopsy has good safety. Early examination of fiberoptic bronchoscopy can provide pathogenic diagnostic evidence of bacterial, fungal, Pneumocystis jirovecii and viral infections, thus improving the diagnostic rate.
ABSTRACT
Objective:To investigate the efficacy and safety of SIMPLE regimen in the treatment of extranodal NK/T-cell lymphoma (ENKTCL).Methods:The clinical data of 11 patients with ENKTCL who were admitted to the University of Hong Kong-Shenzhen Hospital from January 2012 to January 2022 were retrospectively analyzed. The patients received 4-6 courses of SIMPLE (cisplatin, gemcitabine, ifosfamide, etoposide, dexamethasone, and pegasparaginase) regimen chemotherapy, and stage Ⅰ and Ⅱ patients who also received local radiotherapy after 2 or 3 courses of chemotherapy. Patients were evaluated for mid-treatment and end-of-treatment outcomes, and the adverse effects of patients were evaluated in each treatment cycle. The Kaplan-Meier method was used to analyze the progression-free survival (PFS) and overall survival (OS) of the 11 patients.Results:All 11 patients were nasal type, with the median age of 41 years old (26-67 years old), including 5 males and 6 females, 3 relapsed cases and 8 newly treated cases. Of the 10 patients evaluated for efficacy, 9 achieved complete remission and 1 achieved at least partial remission (efficacy was assessed based on follow-up). All 11 patients were followed up for a median time of 50 months (15-72 months) and 2 relapsed patients died due to disease progression. The expected 5-year PFS rate and OS rate of 11 patients were both 90.0%, and the expected 5-year OS rate was 100.0% and 66.6% in newly treated and relapsed patients, respectively. Common adverse effects were hematologic adverse reactions, infections, gastrointestinal symptoms, elevated transaminases, and hypofibrinogenemia, all of which were curable. There is no treatment-related death.Conclusions:The SIMPLE regimen for the treatment of ENKTCL has a high remission rate, the patients have long survival time, and the regimen is moderately well tolerated.
ABSTRACT
OBJECTIVE To study the effects of disodium cantharidinate on the pharmacokinetic behavior of capecitabine in rats. METHODS Rats were randomly divided into two control groups and two experimental groups with 6 rats in each group. Two control groups were intraperitoneally injected with normal saline， and two experimental groups were intraperitoneally injected with Disodium cantharidinate injection of 0.5 mL/kg， for 7 consecutive days. Eight days after medication， control group 1 and experimental group 1 were given capecitabine 5 mg/kg intragastrically， while control group 2 and experimental group 2 were given capecitabine 5 mg/kg intravenously. Blood samples were collected at different time points after administration. After extraction with ethyl acetate， the concentration of capecitabine in rat plasma was determined by UPLC-MS/MS method using tolbutamide as the internal standard. The pharmacokinetic parameters were calculated by DAS 2.0 software. RESULTS Compared with control group 1， MRT0－∞， cmax， AUC0－30 h， AUC0－∞ and F of experimental group 1 were increased significantly， while CLz/F was decreased significantly （P＜0.01）. Compared with control group 2， t1/2， MRT0－30 h， MRT0-∞， AUC0－30 h and AUC0－∞ of experimental group 2 were increased significantly （P＜0.01）. CONCLUSIONS Disodium cantharidinate can increase the plasma exposure of capecitabine in rats， improve its oral bioavailability， prolong the average residence time， and reduce its clearance rate.
ABSTRACT
ObjectiveTo discuss the origin of rare abnormal karyotypes of fetuses with high risk of trisomy 18 revealed by non-invasive prenatal testing （NIPT） and its impact on fertility. MethodsThe cytogenetic and molecular genetic analyses were performed on the abnormal chromosomes of a prenatally diagnosed fetus with rare complete translocation trisomy 18. Using the keywords “translocation trisomy 18” or “trisomy 18 translocation” in both Chinese and English， we searched PubMed， CNKI， SinoMed， WanFang Data， CQ VIP and the Chinese Medicine database. The relevant case series were retrieved and critically appraised. ResultsG-banded karyotype analysis showed that the maternal karyotype was 46，XX，t（9；18）（q31.2；q23） and the fetal karyotype was 47， XN， t （9； 18） （q31.2；q23）mat， +18， which was a rare complete translocation type of trisomy 18. The SNP array revealed the fetus had increased copy number of chromosome 18 and two complete chromosome 18 inherited from the mother with balanced chromosomal translocation. Literature search found two children with complete translocation trisomy 18 reported abroad. Both of them had trisomy 18 phenotype and originated from the balanced translocation between parental chromosome 18 and other chromosomes. ConclusionNIPT gives an effective advance warning of trisomy 18. SNP array not only improves the detection rate of chromosomal abnormalities， but also helps identify the origin. The karyotype is still the gold standard for prenatal diagnosis.
ABSTRACT
Objective: To assess the cardiovascular health status of adults in China by using the "Life's Essential 8" score, and provide reference for the development and improvement of cardiovascular disease prevention and control policies and measures. Methods: Chronic Disease and Nutrition Surveillance was conducted in 298 counties/districts in 2015 in 31 provinces (autonomous regions, municipalities) across China, multi-stage stratified cluster random sampling was used to select 45 households in each village or neighborhood, and 20 households were further selected to conduct dietary surveys. In this study, a total of 70 093 adults aged ≥20 years who completed the dietary survey and had complete information were included, their cardiovascular health status were assessed by using the "Life's Essential 8" score, a cardiovascular health scoring standard released by the American Heart Association in 2022. All results were adjusted using complex design-based sampling weights to achieve a better estimate of the population. Results: In 2015, the overall cardiovascular health score of Chinese adults aged ≥20 years was 73.3±12.6, the score was significantly higher in women (77.9±11.6) than in men (68.7±11.8), and higher in urban area (74.5±12.8) than in rural area (71.9±12.2), the differences were significant (P<0.001). It was estimated that about 0.25% (95%CI: 0.16%-0.33%) of adults in China had cardiovascular health score of 100, and 33.0% (95%CI: 31.6%-34.3%), 63.2% (95%CI: 62.1%-64.3%), and 3.9% (95%CI: 3.5%-4.2%) of adults had high, moderate and low cardiovascular health scores, respectively. The proportion of those with high cardiovascular health scores was relatively low in men, those with low education level, those with low income, those living in rural areas, and those living in southwest China (P<0.001). Of the eight factors, diet had the lowest mean score (46.0, 95%CI: 44.7-47.3), followed by blood pressure (59.4, 95%CI: 58.2-60.6) and tobacco exposure (61.4, 95%CI: 60.6-62.2). Conclusions: The cardiovascular health status of two-thirds of adult population in China needs to be improved. Diet, tobacco exposure, and blood pressure are the factors affecting the cardiovascular health of Chinese population, to which close attention needs to be paid, and men, rural residents, and those with lower socioeconomic status are key groups in cardiovascular health promotion.

Objective: To understand the health examination rate and its changing trend in adults in China from 2010 to 2018, identify the main factors affecting the health examination rate and provide data support for decision making of health intervention. Methods: Data from China Chronic Disease and Risk Factor Surveillance in 2010, 2013, 2015 and 2018 were used. After complex weighting of the data, the rates of health examination, its changing trends and reasons for receiving health examination in adults were analyzed. Average annual percent change (AAPC) was used to describe the changing trend. Anderson model was used as the analysis framework. Multivariate logistic regression model was used to identify the influencing factors for the health examination rate. Results: From 2010 to 2018, the health examination rate in adults increased from 28.2% (95%CI: 24.8%-31.6%) to 41.0% (95%CI: 38.9%-43.1%, P for trend <0.001), the AAPC was 5.47%, the annual average increase was more obvious in those with lower education level and lower income level and in those living in rural area and in western China. In 2018, people received health examination mainly due to providing without charge by community (36.7%) and working unit (28.5%). The results of multivariate analysis showed that being women, age ≥45 years, education level of junior high school or above, living in urban areas, medical insurance, annual income ≥24 000 RMB, suffering from multiple chronic diseases, non-smoking, drinking, adequate physical activity were positive factors for receiving health examination. Conclusion: The rate of health examination in adults increased in China during 2010-2018, and the main reason for receiving health examination is free of charge.

Traffic-related air pollution and noise are becoming increasingly prominent issues in the context of urbanization, both of which are modifiable environmental risk factors for cardiovascular diseases. Those two kinds of traffic-related pollution may have combined effects on the cardiovascular system of human beings, but the biological mechanisms by which they may interact have not been elucidated yet. Thus, we reviewed the research progress based on published population-based and mechanism studies from five aspects, including oxidative stress, inflammatory response, nervous system activation and stress hormones, coagulation dysfunction, and endothelial dysfunction, providing indications for possible common biological pathways. Future studies can construct co-exposure scenarios for traffic-related air pollution and noise to explore their common biological mechanisms in the cardiovascular system by examining the reviewed pathways to provide a scientific basis for the protection of susceptible populations. In addition, the effect modification by individual characteristics and underlying diseases may merit further exploration.
ABSTRACT
Background Epidemiological evidence indicates an association of particulate matter with depression and cognitive performance. From 2013 to 2017, China implemented the Air Pollution Prevention and Control Action Plan to reduce particulate matter concentration. There are few studies on the relationship between the decrease of particulate matter concentration and the improvement of mental health in middle-aged and elderly people. Objective To analyze the relationship between the decrease of city-level particulate matter concentration and the improvement of depression and cognitive function in the middle-aged and elderly population after the implementation of the Air Pollution Prevention and Control Action Plan. Methods Using the China Health and Retirement Longitudinal Study (CHARLS) data in 2011 and 2018, this study applied longitudinal data clustering technology to group cities based on the actual response of each city to the policy (the dynamic change trajectory of PM2.5 in each city during the study period); the higher the degree of response, the greater the reduction of PM2.5 concentration in the city. We assigned participants to three groups with different degrees of response to the policy, including low-response group A as the control group, medium-response intervention group B, and high-response intervention group C. A difference-in-differences (DID) model was used to estimate the influence of PM2.5 decline on the depression and cognitive function among middle-aged and elderly people in China by considering potential individual and city-level time-varying confounders. Depression was measured using the 10-item Center for the Epidemiological Studies of Depression Scale (CES-D10) (10 questions, total score range 0-30) with higher score representing higher severity of depression. Cognitive function was evaluated with reference to the international cognitive function test questionnaire for the middle-aged and the elderly which was further categorized into two dimensions of memory and cognitive status and included 31 questions with a score range of 0-31; the higher the score, the better the cognitive function. Samples with relatively complete outcomes were selected for analysis, including 10729 people in depression analysis and 4510 people in cognitive analysis. Results The longitudinal clustering results indicated that the urban groups with the highest decline of PM2.5 concentrations (high-response group C) had the highest baseline PM2.5 concentrations, mainly in Beijing-Tianjin-Hebei region, Chengdu-Chongqing metropolitan area, and Wuhan metropolitan area. In 2011, no significant differences were observed in depression and cognitive function among the three groups of middle-aged and elderly populations (Kruskal Wallis test: Pdepression=0.864, Pcognition=0.239). Significant differences were found in depression and cognitive function in both low-response group A and medium-response group B in 2018 compared to 2011 (paired Wilcox test, all P<0.001). However, in the high-response group C, there was no significant difference in depression in 2018 compared to 2011 (P=0.195), while a significant difference was detected in cognitive function (P=0.006). As PM2.5 concentrations decreased, the DID model showed that the depression of the middle-aged and elderly people in the high-response group C decreased by 7.55% (95%CI: 2.83%-12.03%), and the cognitive function improved by 2.70% (95%CI: 0.25%-5.22%) compared with the low-response group A. However, no intervention effect was observed in group B with moderate response level compared with group A with low response level. Conclusion After the implementation of the Air Pollution Prevention and Control Action Plan policy, the decrease of PM2.5 concentration has an ameliorative effect on the depression and cognitive function of middle-aged and elderly people in China. Given the aging population and the increasing burden of mental-related diseases in China, the promotion of environmental air pollution control has important public health implications.
ABSTRACT
Abstract@#Allergic diseases can occur in all systems of the body, covering the whole life cycle, from children to adults and to old age, can be lifelong onset and even fatal in severe cases. Children account for the largest proportion of the victims of allergic disease, Children s allergies start from scratch, ranging from mild to severe, from less to more, from single to multiple systems and systemic performance, so the prevention and treatment of allergic diseases in children is of great importance, which can not only prevent high risk allergic conditions from developing into allergic diseases, but also further block the process of allergy. At present, there is no consensus on the management system of allergic children in kindergartens and primary schools. The "Consensus on Allergy Management and Prevention in Kindergartens and Primary Schools", which includes the organizational structure, system construction and management of allergic children, provides evidence informed recommendations for the long term comprehensive management of allergic children in kindergartens and primary schools, and provides a basis for the establishment of the prevention system for allergic children.
ABSTRACT
Objective To examine the antiplatelet effect of ticagrelor by microfluidic chip and flow cytometry under shear stress in vitro. Methods Microfluidic chip was used to examine the effect of ticagrelor on platelet aggregation at the shear rates of 300/s and 1500/s.We adopted the surface coverage of platelet aggregation to calculate the half inhibition rate of ticagrelor.The inhibitory effect of ticagrelor on ADP-induced platelet aggregation was verified by optical turbidimetry.Microfluidic chip was used to construct an in vitro vascular stenosis model,with which the platelet reactivity under high shear rate was determined.Furthermore,the effect of ticagrelor on the expression of fibrinogen receptor (PAC-1) and P-selectin (CD62P) on platelet membrane activated by high shear rate was analyzed by flow cytometry. Results At the shear rates of 300/s and 1500/s,ticagrelor inhibited platelet aggregation in a concentration-dependent manner,and the inhibition at 300/s was stronger than that at 1500/s (both P<0.001).Ticagrelor at a concentration ≥4 μmol/L almost completely inhibited platelet aggregation.The inhibition of ADP-induced platelet aggregation by ticagrelor was similar to the results under flow conditions and also in a concentration-dependent manner.Ticagrelor inhibited the expression of PAC-1 and CD62P. Conclusion We employed microfluidic chip to analyze platelet aggregation and flow cytometry to detect platelet activation,which can reveal the responses of different patients to ticagrelor.

OBJECTIVES@#To study the characteristics of vincristine-induced peripheral neuropathy (VIPN) in children with acute lymphoblastic leukemia (ALL) and the factors influencing the development of VIPN.@*METHODS@#The children with ALL, aged 1-18 years, who were treated with CCCG-ALL2015 or CCCG-ALL2020 regimen in the Affiliated Hospital of Guizhou Medical University from January 2018 to February 2022 were enrolled as subjects. According to the influence of age on risk, the children were divided into 1-10 years group with 91 children and >10 years group with 29 children. VIPN was graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (5th edition), and the incidence rate, severity, and type of VIPN were compared between different groups.@*RESULTS@#A total of 120 children were enrolled in this study, among whom 56 (46.7%) developed VIPN. The >10 years group had a significantly higher incidence rate of VIPN than the 1-10 years group (69% vs 40%, P<0.05). Among the 56 children with VIPN, 12 (21%) had grade 3 VIPN or above, and 44 (79%) had grade 2 VIPN. There were 77 cases of autonomic nerve symptoms (59.7%), 42 cases of peripheral nerve injury (32.5%), and 10 cases of cranial nerve injury (7.8%). There were no significant differences in the severity and type of VIPN between the groups with different ages, sexes, degrees of risk, or treatment regimens (P>0.05). The results of binary logistic regression analysis showed that age is the influencing factor for the occurrence of VIPN (P>0.05).@*CONCLUSIONS@#There is a relatively high incidence rate of VIPN in children with ALL, with the highest incidence rate of autonomic nervous symptoms. The incidence of VIP in children over 10 years old is relatively high.

Objective: To explore the associations of glycated hemoglobin (HbA1c) with FPG and oral glucose tolerance test 2-hour (OGTT-2 h) in areas at different altitude in China. Methods: Subjects who participated in 2018-2019 China Chronic Disease and Risk Factor Surveillance and had no prior type 2 diabetes diagnosis were included. Subsequently, they were categorized into three groups based on altitude of living area (<2 000, 2 000- and ≥3 000 m). With adjustment for intracluster correlation, multivariable linear regression analysis was performed to evaluate the associations of HbA1c with FPG and OGTT-2 h in the context of HbA1c was normal (<5.7%) or abnormal (≥5.7%). Furthermore, the shape of relationships between HbA1c and glucose indicators was examined using restricted cubic spline. Finally, receiver operating characteristic curve was used to evaluate the diagnostic performance of HbA1c for diabetes. Results: A total of 157 277 subjects were included in the analysis. While FPG and OGTT-2 h levels gradually decreased with increase of altitude, HbA1c level was similar among the three groups. When HbA1c was <5.7%, its association with FPG and OGTT-2 h was weak and no obvious difference was observed among the three groups. When HbA1c was ≥5.7%, the FPG and OGTT-2 h increased by 15.45% (95%CI:14.71%- 16.18%) and 24.54% (95%CI:23.18%-25.91%) respectively per one standard deviation increase in HbA1c in group in area at altitude <2 000 m. However, the FPG and OGTT-2 h increased by 13.08% (95%CI:10.46%-15.76%) and 21.72% (95%CI:16.39%-27.31%), respectively, in group in area at altitude 2 000- m, and increased by 11.41% (95%CI:9.32%-13.53%) and 20.03% (95%CI:15.38%- 24.86%), respectively, in group of altitude ≥3 000 m. The restricted cubic spline indicated that the curve showing the association of HbA1c with FPG and OGTT-2 h was flat when HbA1c was <5.7%, but showed a positive linear relationship when HbA1c was ≥5.7%. The area under curve for detecting diabetes was 0.808 (95%CI:0.803-0.812) in group of altitude <2 000 m and 0.728 (95%CI:0.660-0.796, P=0.022) in group of altitude ≥3 000 m. The relevant optimal cutoff value of HbA1c was 5.7%, with a sensitivity of 65.4% and a specificity of 83.0%, and 6.0%, with a sensitivity of 48.3% and a specificity of 93.7%, respectively. Conclusions: When HbA1c was ≥5.7%, the association between HbA1c and glucose indicators became weaker as the increase of altitude. In the area at altitude ≥3 000 m, it may not be appropriate to use HbA1c in the diagnosis of diabetes.

Objective: To investigate the clinical characteristics of abnormal liver function in patients with advanced esophageal squamous carcinoma treated with programmed death-1 (PD-1) antibody SHR-1210 alone or in combination with apatinib and chemotherapy. Methods: Clinical data of 73 patients with esophageal squamous carcinoma from 2 prospective clinical studies conducted at the Cancer Hospital Chinese Academy of Medical Sciences from May 11, 2016, to November 19, 2019, were analyzed, and logistic regression analysis was used for the analysis of influencing factors. Results: Of the 73 patients, 35 had abnormal liver function. 13 of the 43 patients treated with PD-1 antibody monotherapy (PD-1 monotherapy group) had abnormal liver function, and the median time to first abnormal liver function was 55 days. Of the 30 patients treated with PD-1 antibody in combination with apatinib and chemotherapy (PD-1 combination group), 22 had abnormal liver function, and the median time to first abnormal liver function was 41 days. Of the 35 patients with abnormal liver function, 2 had clinical symptoms, including malaise and loss of appetite, and 1 had jaundice. 28 of the 35 patients with abnormal liver function returned to normal and 7 improved to grade 1, and none of the patients had serious life-threatening or fatal liver function abnormalities. Combination therapy was a risk factor for patients to develop abnormal liver function (P=0.007). Conclusions: Most of the liver function abnormalities that occur during treatment with PD-1 antibody SHR-1210 alone or in combination with apatinib and chemotherapy are mild, and liver function can return to normal or improve with symptomatic treatment. For patients who receive PD-1 antibody in combination with targeted therapy and chemotherapy and have a history of long-term previous smoking, alcohol consumption and hepatitis B virus infection, liver function should be monitored and actively managed in a timely manner.

Objective: To evaluate the safety and efficacy of anlotinib plus irinotecan in the second-line treatment of patients with metastatic colorectal cancer (mCRC). Methods: This prospective phase 1/2 study was conducted in 2 centers in China (Cancer Hospital of Chinese Academy of Medical Sciences and Jiangsu Province Hospital). We enrolled patients with mCRC whose disease had progressed after first-line systemic therapy and had not previously treated with irinotecan to receive anlotinib plus irinotecan. In the phase 1 of the trial, patients received anlotinib (8 mg, 10 mg or 12 mg, po, 2 weeks on/1 week off) in combination with fixed-dose irinotecan (180 mg/m(2), iv, q2w) to define the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D). In the phase 2, patients were treated with the RP2D of anlotinib and irinotecan. The primary endpoints were MTD and objective response rate (ORR). Results: From May 2018 to January 2020, a total of 31 patients with mCRC were enrolled. Anlotinib was well tolerated in combination with irinotecan with no MTD identified in the phase 1, and the RP2D was 12 mg. Thirty patients were evaluable for efficacy analysis. Eight patients achieved partial response, and 21 had stable disease, 1 had progressive disease. The ORR was 25.8% and the disease control rate was 93.5%. With a median follow-up duration of 29.5 months, the median progression-free survival and overall survival were 6.9 months (95% CI: 3.7, 9.3) and 17.6 months (95% CI: 12.4, not evaluated), respectively. The most common grade 3 treatment-related adverse events (≥10%) were neutropenia (25.8%) and diarrhea (16.1%). There was no treatment-related death. Conclusion: The combination of anlotinib and irinotecan has promising anti-tumor activity in the second-line treatment of mCRC with a manageable safety profile.

In recent years, immunotherapy represented by immune checkpoint inhibitors programmed death 1 (PD-1) has made great progress in the treatment of esophageal cancer and is rewriting the global paradigm for the treatment of esophageal cancer. According to current data, only a small number of patients with esophageal cancer could benefit from immunotherapy. Therefore, it is a challenge to screen the potential beneficiaries of PD-1 inhibitors. Studies have shown that the expression level of programmed death-ligand 1 (PD-L1) in esophageal cancer is closely associated with the efficacy of PD-1 inhibitors, and PD-L1 is the most important predictive biomarker of the efficacy of PD-1 inhibitors. With the clinical application of different PD-1 inhibitors and PD-L1 protein expression detection platforms, clarifying the clinical significance and timing of detection of PD-L1 protein expression in esophageal cancer, and establishing a standardized PD-L1 testing procedure, are of great significance to improve the accuracy of detection and reduce the difference between laboratories, so as to maximize the therapeutic benefits for patients. This consensus was finally reached, based on the combination of literature, expert experience, and internal discussion and voting of committee members, to provide an accurate and reliable evidence for clinicians to make decisions.

Colorectal cancer （CRC） is one of the leading causes of cancer-related deaths worldwide， with increasing incidence and mortality rates. The disease often develops covertly and lacks specific symptoms in its early stages， leading to late-stage diagnoses in most patients. It has become a prominent research topic in the field of digestive system tumors. The exact mechanisms underlying CRC are not yet clear and involve factors such as genetics， gene mutations， inflammatory responses， and aberrant activation of tumor-related signaling pathways. Nuclear factor-kappa B （NF-κB） is a crucial transcription factor that participates in various biological processes， including inflammatory responses， immune responses， cell proliferation， and apoptosis. Research suggests that NF-κB， serving as a molecular link between inflammation and cancer， is highly expressed in CRC. It promotes the occurrence and development of CRC by regulating the activity of target genes such as cell pro-inflammatory factors， chemokines， angiogenic factors， metastasis factors， and anti-apoptotic proteins. Currently， common treatments for CRC include surgery， radiation therapy， and chemotherapy drugs like 5-fluorouracil. However， these treatments have limitations such as significant adverse reactions， high metastasis rates， and the development of drug resistance. Therefore， the search for effective， low-adverse-reaction drugs to replace or supplement current treatments is essential. In recent years， traditional Chinese medicine （TCM） has shown some effectiveness in preventing and treating CRC. TCM has been found to inhibit the growth of CRC cells by modulating the NF-κB signaling pathway， playing a positive role in the occurrence and progression of CRC. Based on the asthenia in origin and sthenia in superficiality and deficiency-excess in complexity in CRC， this article summarized and analyzed the mechanisms and effects of TCM interventions targeting the NF-κB signaling pathway in CRC， and reviewed advances of 10 Chinese medicinal compound formulas and 37 Chinese medicinal monomer components of different types， including flavonoids， phenols， alkaloids， glycosides， and terpenoids with the effects of dispelling pathogenic factors， reinforcing healthy qi， and removing toxins in the prevention and treatment of CRC by targeting the NF-κB pathway. It is found that Chinese medicine can inhibit CRC cell proliferation， invasion， metastasis， angiogenesis， and inflammation by modulating the NF-κB signaling pathway， induce cell apoptosis， restore drug and radiation sensitivity， and counteract CRC. This article is expected to provide insights and references for the in-depth exploration and treatment of CRC mechanisms.
ABSTRACT
OBJECTIVE@#To investigate the spatial patterns of the prevalence, awareness, treatment, and control rates of dyslipidemia at the provincial level in China.@*METHODS@#A national and provincial representative cross-sectional survey was conducted among 178,558 Chinese adults in 31 provinces in mainland China in 2018-2019, using a multi-stage, stratified, cluster-randomized sampling design. Subjects, as households, were selected, followed by a home visit to collect information. Both descriptive and linear regression procedures were applied in the analyses.@*RESULTS@#The overall prevalence of dyslipidemia was 35.6%, and wide geographic variations of prevalence, treatment, and control rates of dyslipidemia were identified among 178,558 eligible participants with a mean age of 55.1 ± 13.8 years. The highest-lowest difference regarding the provincial level prevalence rates were 19.7% vs. 2.1% for high low-density lipoprotein cholesterol, 16.7% vs. 2.5% for high total cholesterol, 35.9% vs. 5.4% for high triglycerides, and 31.4% vs. 10.5% for low high-density lipoprotein cholesterol. The treatment rate of dyslipidemia was correlated with the socio-demographic index ( P < 0.001), urbanization rate ( P = 0.01), and affordable basic technologies and essential medicines ( P < 0.001).@*CONCLUSION@#Prevailing dyslipidemia among the Chinese population and its wide geographic variations in prevalence, treatment, and control suggest that China needs both integrated and localized public health strategies across provinces to improve lipid management.
