Lung cancer is the most common malignant tumor worldwide, ranking first in both incidence and mortality rates. According to the latest statistics from the International Agency for Research on Cancer (IARC), approximately 2.5 million new cases and around 1.8 million deaths from lung cancer occurred in 2022, placing a tremendous burden on global healthcare systems. The high mortality rate of lung cancer is closely linked to its subtle early symptoms, which often lead to diagnosis at advanced stages. This not only complicates treatment but also results in substantial economic losses. Current treatment options for lung cancer include surgery, radiotherapy, chemotherapy, targeted drug therapy, and immunotherapy. Among these, immunotherapy has emerged as the most groundbreaking advancement in recent years, owing to its unique antitumor mechanisms and impressive clinical benefits. Unlike traditional therapies such as radiotherapy and chemotherapy, immunotherapy activates or enhances the patient’s immune system to recognize and eliminate tumor cells. It offers advantages such as more durable therapeutic effects and relatively fewer toxic side effects. The main approaches to lung cancer immunotherapy include immune checkpoint inhibitors, tumor-specific antigen-targeted therapies, adoptive cell therapies, cancer vaccines, and oncolytic virus therapies. Among these, immune checkpoint inhibitors and tumor-specific antigen-targeted therapies have received approval from the U.S. Food and Drug Administration (FDA) for clinical use in lung cancer, significantly improving outcomes for patients with advanced non-small cell lung cancer. Although other immunotherapy strategies are still in clinical trials, they show great potential in improving treatment precision and efficacy. This article systematically reviews the latest research progress in lung cancer immunotherapy, including the development of novel immune checkpoint molecules, optimization of treatment strategies, identification of predictive biomarkers, and findings from recent clinical trials. It also discusses the current challenges in the field and outlines future directions, such as the development of next-generation immunotherapeutic agents, exploration of more effective combination regimens, and the establishment of precise efficacy prediction systems. The aim is to provide a valuable reference for the continued advancement of lung cancer immunotherapy.

Objective To investigate the genetic causes of auditory neuropathy with optic atrophy in a family.Methods The proband's medical history and family history were inquired in detail,and relevant clinical examina-tions were performed to confirm the diagnosis of auditory neuropathy with optic atrophy,and the genetic pedigree of the family was drawn.Peripheral blood of proband(Ⅲ-7)was collected for whole exome sequencing,and the patho-genicity of the detected mutations were interpreted.Blood samples of proband's wife(Ⅲ-8),eldest daughter(Ⅳ-7),second daughter(Ⅳ-9)and son(Ⅳ-10)were tested for mutation sites by Sanger sequencing.Combined with clinical manifestations and examination results,the family was studied.Results The genetic pattern of this family was autosomal dominant.The proband showed decreased visual acuity at the age of 19,bilateral sensorineural deaf-ness at the age of 30,and decreased speech recognition rate.Among 20 members of the family of 5 generations,10(2 deceased)showed similar symptoms of hearing and visual impairment.Proband(Ⅲ-7),eldest daughter(Ⅳ-7)and son(Ⅳ-10)underwent relevant examination.Pure tone audiometry showed bilateral sensorineural deafness.ABR showed no response bilaterally.The 40 Hz AERP showed no response in both ears.OAE showed responses in some or all of the frequencies.No stapedial reflex was detected.The eye movement of Ⅲ-7 and Ⅳ-10 were reasona-ble in all directions,and color vision was normal.Ocular papilla atrophy was observed in different degrees in fundus examination.OCT showed thinning of optic disc nerve fibers in both eyes,and visual evoked potential showed pro-longed P100 wave peak.They were diagnosed as hereditary auditory neuropathy with optic atrophy.A mutation of the OPA1 gene c.1334G＞A(p.Arg445His,NM_015560.2)at a pathogenic locus on chromosome 3 was detected by whole exon detection in Ⅲ-7.The results of generation sequencing analysis showed that the OPA1 gene c.1334G＞A(p.Arg445His,NM_015560.2)mutation of chromosome 3 was also found in Ⅳ-7 and Ⅳ-10.Meanwhile,the gen-otypes of Ⅲ-8 and Ⅳ-9 were wild homozygous,that is,no mutation occurred.Conclusion The OPA1 c.1334G＞A(p.Arg445His,NM_015560.2)mutation site might be the pathogenic mutation in this family.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Objective To construct luciferase reporter plasmids of truncated fragments of different lengths of human guanylate binding protein 5(GBP5)gene promoter and analyze the transcriptional activity of each fragment to determine the core regulatory region.Methods GBP5promoter sequence was amplified by PCR,truncated into five fragments of different lengths and connected to pGL3-basic plasmid.The constructed recombinant plasmids pGL3-GBP5-11/21/31/41/51were transfected into 293FT cells and detected for luciferase activity.The binding sites of transcription factors in GBP5promoter region were predicted by JASPAR software,and Yin-Yang transcription factor 1(YY1)targeting the core regulatory region was selected and verified for the transcriptional regulatory activity.The CDS sequence of YY1 was amplified by PCR to construct the overexpression plasmid pIRES2-EGFP-YY1,which was then co-transfected to 293FT cells with plasmids pGL3-GBP5-21(-1 623 ～ +47 bp)and internal reference plasmid pRL-CMV,and detected for luciferase activity to analyze the regulation of transcription factor YY1 on GBP5 promoter activity.Results Colony PCR and double enzyme digestion identification proved that the plasmid of human GBP5 promoter reporter gene was correctly constructed;JASPAR software predicted that there were multiple transcription factor binding sites such as STAT1,YY1 and Foxp3 in GBP5promoter region.Double luciferase activity assay showed that pGL3-GBP5-21(-1 623 ～ +47 bp)showed the highest promoter activity,while the promoter activity of pGL3-GBP5-41(-520 ～ +47 bp)decreased significantly,suggesting that the core region of GBP5 promoter was located at upstream-1 623 ～-520 bp of 5 'UTR;Overexpression of YY1 significantly activated the GBP5 promoter activity and regulated the expression of GBP5.Conclusion The core regulatory region of human GBP5 promoter was located in upstream-1 623 ～-520 bp of the 5 'UTR,with a binding site of transcription factor YY1 existing in this region.Meanwhile,overexpression of YY1 significantly effected the activity of GBP5 promoter.

To clarify the content characteristics of the main active components and mineral elements of Cynomorium songaricum under different habitat conditions, and further explore the relationship between the quality of C. songaricum and habitats, this study took C. songaricum from 25 different habitats in China as the research object, and measured the contents of 8 main active components and 12 mineral elements separately. Diversity analysis, correlation analysis, principal component analysis and cluster analysis were carried out. The results showed that the genetic diversity of total flavonoids, ursolic acid, ether extract, potassium(K), phosphorus(P) and zinc(Zn) in C. songaricum was high. The coefficient of variation of crude polysaccharide, ether extract, gallic acid, protocatechuic aldehyde, catechin, epicatechin, calcium(Ca), sodium(Na), magnesium(Mg), sulfur(S), iron(Fe), manganese(Mn), selenium(Se) and nickel(Ni) were all over 36%, indicating that the quality of C. songaricum was significantly affected by habitats. There were strong synergistic and weak antagonistic effects among the contents of the 8 active components, and complex antagonistic and synergistic effects among the contents of the 12 mineral elements. Principal component analysis revealed that crude polysaccharide, ursolic acid, catechin, epicatechin and total flavonoids could be used as the characteristic components to evaluate the quality of C. songaricum, and Na, copper(Cu), Mn and Ni were the characteristic elements to evaluate the quality of C. songaricum. In cluster ana-lysis, the second group with the main active components as cluster center had better quality in terms of the content of active substances, and the second group with the mineral elements as cluster center had higher utilization potential in the exploitation of mineral elements. This study could provide a basis for resource evaluation and breeding of excellent varieties of C. songaricum in different habitats, and provide a reference for cultivation and identification of C. songaricum.

Objective:To investigate the clinicopathological and molecular genetic characteristics and prognosis of patients with diffuse large B-cell lymphoma (DLBCL).Methods:The clinicopathological data of 152 DLBCL patients receiving consultation and routine physical examination in Peking University Third Hospital and Peking University School of Basic Medicine from January 2008 to December 2015 were retrospectively analyzed. Immunohistochemistry was used to detect the expressions of CD10, bcl-6, MUM1, GCET1, FOXP1. EB virus encoded small RNA (EBV-EBER) was detected by using in situ hybridization. The aberrations of bcl-2, bcl-6 and c-myc genes were detected by using fluorescence in situ hybridization (FISH) to screen double-hit lymphoma (DHL). Kaplan-Meier method was used to make survival analysis.Results:Among 152 cases of DLBCL, the ratio of male to female was 1.49:1, the median age of onset was 59 years (7-90 years), and 79 cases (52.0%) were primary lymph nodes. The median overall survival (OS) time of all cases was 16 months (1-101 months). The 1-year, 3-year and 5-year OS rates were 70.2%, 44.7%, 30.3%, respectively. The OS of R-CHOP treatment group was better than that of CHOP treatment group and untreated group ( P = 0.001). Among all 137 patients receiving double-hit histochemistry score (DHS), there were 56 cases with 0 score, 57 cases with 1 score, 24 cases with 2 scores; and the difference in the OS of different DHS score groups ( P = 0.311). FISH detection showed that among 29 cases achieving results of c-myc gene detection, there were 2 cases of splitting gene and 3 cases of gene amplification; among 26 cases achieving results of bcl-2 gene detection, 2 cases had bcl-2 gene amplification; among 26 cases achieving results of bcl-6 gene detection, 2 cases had bcl-6 gene amplification and 3 cases had splitting gene. It was found that myc and bcl-2 genes were amplified simultaneously in 1 case, accompanied with bcl-6 gene splitting, which was called triple-hit lymphoma. In DHS 0-score group, 1 case of double gene abnormality was found, and 1 case of single gene abnormality was found in group 1-score; in group 2-score, 5 cases were single gene abnormality and 1 case was three gene abnormality, so the gene abnormality was inconsistent with the protein expression. Conclusions:The incidence of DHL in DLBCL patients in China is low. The major gene abnormalities are c-myc or bcl-2, bcl-6 single gene abnormalities.

Objective:To investigate the clinical application value of left ventricular myocardial strain obtained by cardiac MR (CMR) in recent major adverse cardiovascular events (MACE) in patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI).Methods:From January 2020 to December 2020, a total of 163 patients successfully underwent primary PCI and underwent CMR examination within one week after surgery at Affiliated Hospital of Xuzhou Medical University. The scan sequences included rapid balance-fast field echo and late-gadolinium enhancement. CVI42 post-processing software was used to analyze and measure the left ventricular myocardial strain indices, including left ventricular global longitudinal strain (GLS), left ventricular global circumferential strain (GCS), and left ventricular global radial strain (GRS). According to the results of the 1-year follow-up after surgery, the patients were divided into the MACE group ( n=28) and the non-MACE group ( n=135). For continuous variables with a normal distribution, the t test of two independent samples was used for comparisons between groups. For continuous variables with an abnormal distribution, the variables were compared and analyzed by the rank sum test. For categorical variables, the χ 2 tests were used for between-group comparisons. Cox regression was used to analyze the prognostic value of myocardial strain on the development of MACE in patients with STEMI. The receiver operating characteristic (ROC) curve was used to analyze the diagnostic efficacy of myocardial strain parameters, and the optimal cut-off value was evaluated by calculating the Youden index. Results:The GLS, GCS, and GRS of the MACE group were (-10.4±3.3)%, [-11.9 (-14.5, -9.3)]%, and (18.3±6.3)%, respectively, and those of the non-MACE group were (-13.7±3.4)%, [-14.6 (-16.4, -11.7)]%, and (22.3±6.1)%, respectively. The difference between the two groups was statistically significant ( t/ Z=-4.71, -3.04, 3.21, P<0.05). Multivariate Cox regression analysis showed that GLS was an independent predictor of MACE (HR=1.546, 95%CI 1.180-2.027, P=0.002). The ROC curve analysis showed that GLS had the largest area under the curve (AUC) (AUC=0.754, 95%CI 0.658-0.851, P<0.001), with a cut-off value of -12.45%. Its diagnostic sensitivity was 71.4%, and the specificity was 67.4%. The value was better than that of the traditional predictor of STEMI prognosis, namely, left ventricular ejection fraction (AUC=0.680, 95%CI 0.567-0.793, P=0.003). Conclusion:GLS of CMR is an independent predictor of MACE in STEMI patients undergoing primary PCI.

Allergic diseases affect about 40% of the world's population. Environmental factors are important in the occurrence and development of allergic diseases. Dust mites are one of the most important allergens in the indoor environment. The World Health Organization proposes the "four-in-one, combination of prevention and treatment" treatment principle for allergic diseases, in which environmental control to avoid or reduce allergens is the first choice for treatment. Modern people spend much more time at home (including sleeping) than outdoors, and the control of the home environment is particularly critical. This practice introduces the hypoallergenic home visit program, which including home environment assessment, environmental and behavioral intervention guidance, and common household hypoallergenic supplies and service guidance for the patient's home environment. The real-time semi-quantitative testing of dust mite allergens, qualitative assessments of other indoor allergens, record of patients' household items and lifestyle, and precise, individualized patient prevention and control education will be conducted. The hypoallergenic home visit program improves the doctors' diagnosis and treatment data dimension, and becomes a patient management tool for doctors outside the hospital. It also helps patients continue to scientifically avoid allergens and irritants in the environment, effectively build a hypoallergenic home environment, reduce exposure to allergens in the home environment, and achieve the goal of combining the prevention and treatment of allergic diseases.
