Lung nodules are characterized by a mixture of deficiency and excess syndromes， with the primary disease location in the lungs and a close relationship to the spleen and kidneys. The pathogenesis involves dysfunction of the lungs， spleen， and kidneys， leading to qi stagnation， phlegm coagulation， and blood stasis， which obstruct the colla-terals， and cold-dampness obstructing the surface and lung qi failing to disperse are important causes of lung nodules. The clinical treatment strategy focuses on regulating the lung collaterals and adopting an internal-external combined approach. Firstly， dredging-techniques such as scraping， fire needling， and filiform-shaped needling are used to unblock stagnation in the collaterals and relieve surface obstructions； secondly， plastering-acupoint application therapy targets the disease site to dissolve nodules and unblock collaterals； thirdly， moxibustion is employed to provide warmth and tonification， preventing the re-accumulation of pathogens； forthly， prescription is used based on the modified Jinshui Liujun Decoction （金水六君煎） combined with Shengxian Decoction （升陷汤） to harmonize the lungs， spleen， and kidneys and to restore organ function.

Phakic intraocular lens implantation has become one of the important means of correcting refractive errors today. Among them,the implantable collamer lens(ICL)is favored for its wide range of correction, excellent optical quality, and high safety, but the risks of postoperative complications such as glaucoma and anterior subcapsular opacification still exist. Vault is an important indicator for evaluating the safety after ICL implantation, and its ideal state is crucial for preventing complications. Studies have shown that iris morphology has a significant impact on vault. In order to further optimize surgical outcomes and improve surgical safety, this review comprehensively reviews the research progress of iris-related parameters in ICL implantation and discusses the importance of various parameters in preoperative evaluation and postoperative follow-up.

Cerebral small vessel disease （CSVD） is a common disease with great impact on the health of the Chinese population. CSVD has insidious progression and is often neglected by both patients and physicians. In recent years， advances have been made in the research on CSVD from the aspects of risk factors， pathogenesis， clinical manifestations， and evaluation systems. In 2013， the international Standards for Reporting Vascular Changes on Neuroimaging （STRIVE） collaborative group standardized the definition and description of CSVD， and subsequently in 2021， our team released Chinese expert consensus on the diagnosis and treatment of cerebral small vessel disease 2021， which summarized the latest research findings in China and globally. In 2023， the international STRIVE collaborative group provided further updates on research advances in the field of CSVD. CSVD has similar clinical manifestations to neurodegenerative diseases， with a lack of significant specificity. Although genetic testing and brain tissue biopsy help to make a confirmed diagnosis to a certain extent， their application in clinical practice has been limited by technical and financial constraints. At present， neuroimaging techniques are mainly used to detect brain tissue lesions induced by CSVD and make a diagnosis. This article discusses the imaging markers for the diagnosis of CSVD and the imaging-based differential diagnosis of CSVD.

Objective To investigate the impact of long non-coding RNA(LncRNA)taurine up-regulated gene 1(TUG1)on high glucose-induced cardiomyocyte apoptosis by regulating miR-181b-5p/programmed cell death protein 4(PDCD4)axis.Methods Diabetic cardiomyopathy(DCM)cell model was established in vitro with high glucose(HG,25 mmol/L glucose).AC16 cells were divided into the NG(5.5 mmol/L glucose)group,the HG group,the HG+sh-NC group,the HG+sh-TUG1 group,the HG+miR-NC group,the HG+miR-181b-5p group,the HG+sh-TUG1+anti-miR-NC group,the HG+sh-TUG1+anti-miR-181b-5p group,the HG+miR-181b-5p+pcDNA group and HG+miR-181b-5p+pc-PDCD4 group.The Cell Counting Kit-8(CCK-8)method was applied to detect cell viability.Lactate dehydrogenase(LDH)assay was applied to detect LDH release.Quantitative real-time polymerase chain reaction(qRT-PCR)was applied to detect expression levels of TUG1,miR-181b-5p and PDCD4 mRNA.Flow cytometry was applied to detect apoptosis.Western blot assay was applied to detect levels of B-cell lymphoma 2-associated X(Bax),activated caspase 3(cleaved caspase 3)and PDCD4 proteins.Caspase-Glo3 assay was applied to assess caspase 3 activity.Dual-luciferase reporter assay was applied to verify the targeting relationship between TUG1 or PDCD4 and miR-181b-5p.Results Compared with the NG group,the cell activity decreased in the HG group,and LDH release,apoptosis rate,Bax,cleaved caspase 3 expression and caspase 3 activity increased(P＜0.05),which could be antagonized by TUG1 knockdown or miR-181b-5p overexpression(P＜0.05).Inhibition of miR-181b-5p was able to alleviate the impact of TUG1 silencing on cardiomyocyte viability and apoptosis under high glucose treatment(P＜0.05).The overexpression of PDCD4 attenuated the promotion effect of miR-181b-5p up-regulation on the viability of cardiomyocytes treated with high glucose and the inhibitory effect on apoptosis.TUG1 was able to increase the expression of PDCD4 through adsorption of miR-181b-5p(P＜0.05).Conclusion TUG1 promotes high glucose-induced cardiomyocyte apoptosis by down-regulating miR-181b-5p and up-regulating PDCD4.

Objective: To clarify the phenotypes of the newborns with SLC26A4 single-allele mutation in deafness genetic screening and second variant; to analyze the SLC26A4 genotype and hearing phenotype. Methods: 850 newborns born in Beijing from April 2015 to December 2019 were included and there were 468 males and 382 females. They received genetic deafness screening for 9 or 15 variants, with the result of SLC26A4 single-allele mutation. Firstly, three step deafness gene sequencing was adopted in this work, i.e., the first step was "SLC26A4 gene whole exons and splice sites" sequencing; the second step was "SLC26A4 gene promoter, FOXI1 gene and KCNJ10 gene whole exons" sequencing; and the third step was detection for "SLC26A4 gene copy number variation". Secondly, we collected the results of newborn hearing screening for all patients with the second mutation found in the three step test, and conducted audiological examinations, such as acoustic immittance, auditory brainstem response and auditory steady state response. Thirdly, for novel/VUS mutations, we searched the international deafness gene database or software, such as DVD, ClinVar and Mutation Taster, to predict the pathogenicity of mutations according to the ACMG guideline. Lastly, we analyzed the relationship between genotype and phenotype of newborns with SLC26A4 single allele mutation. Results: Among 850 cases, the median age of diagnosis was 4 months. In the first step, 850 cases were sequenced. A total of 32 cases (3.76%, 32/850) of a second variants were detected, including 18 cases (2.12%, 18/850) with identified pathogenic variants; 832 cases were sequenced and 8 cases of KCNJ10 gene missense variants were detected among the second step. No missense mutations in the FOXI1 gene and abnormal SLC26A4 gene promoter were detected; the third step sequencing results were all negative. Genotypes and hearing phenotypes included 18 cases combined with the second clear pathogenic variant, 16 cases (16/18) referred newborn hearing screening and 2 cases (2/18) passed in both ears; degree of hearing loss consisted of 18 profound ears (18/36), 13 severe ears (13/36) and 5 moderate ears (5/36); audiogram patterns comprised 17 high frequency drop ears (17/36), 14 flat ears (14/36), 3 undistinguished ears (3/36), and 2 U shaped ears (2/36); 11 cases underwent imaging examination, all of which were bilateral enlarged vestibular aqueduct. As for 22 cases of other genotypes, all passed neonatal hearing screening and the hearing diagnosis was normal, including 9 cases with VUS or possibly novel benign variants, 8 cases with KCNJ10 double gene heterozygous variants, and 5 cases with double heterozygous variants. Conclusions: The probability of individuals with SLC26A4 single-allele variant who merge with a second pathogenic variant is 2.12%, all of which are SNV, which can provide scientific basis for the genetic diagnosis and genetic counseling of SLC26A4 variants. Those who have merged with second pathogenic variant are all diagnosed with sensorineural hearing loss. Patients with KCNJ10 gene mutations do not manifest hearing loss during the infancy, suggesting the need for further follow-up.

LC3-associated phagocytosis (LAP) is a special phagocytosis occurring at the intersection of the two pathways of phagocytosis and autophagy. A hallmark event of the LAP process is the recruitment of microtubule-associated proteinⅠlight chain type 3-Ⅱ(LC3Ⅱ) to the phagosome surface of the monolayer membrane structure. The LAP pathway relies on the functions of the RUN domain and cysteine-rich domain containing, Beclin 1-interacting protein (Rubicon) and reduced nicotinamide adenine dinucleotide phosphate (NADPH) oxidase. The LC3-associated phagosome (LAPosome) binds to the lysosome to digest and degrade the contents. In recent years, increasing studies have found that LAP plays an important role in the infections caused by pathogenic microorganisms including fungi and bacteria. LAP is a crucial way in the host to resist and degrade the infection of pathogenic microorganisms. However, some pathogenic microorganisms can effectively escape from LAP in the host and even use LAPosome as a place for colonization and replication. This article summarized the recent progress in the role of LAP in host defense against pathogenic microorganism infection and the significance of it in the occurrence and development of diseases.

Objective: To explore the application of manual screening collaborated with the Artificial Intelligence TPS-Assisted Cytologic Screening System in urinary exfoliative cytology and its clinical values. Methods: A total of 3 033 urine exfoliated cytology samples were collected at the Henan People's Hospital, Capital Medical University, Beijing, China. Liquid-based thin-layer cytology was prepared. The slides were manually read under the microscope and digitally presented using a scanner. The intelligent identification and analysis were carried out using an artificial intelligence TPS assisted screening system. The Paris Report Classification System of Urinary Exfoliated Cytology 2022 was used as the evaluation standard. Atypical urothelial cells and even higher grade lesions were considered as positive when evaluating the recognition sensitivity, specificity, and diagnostic accuracy of artificial intelligence-assisted screening systems and human-machine collaborative cytologic screening methods in urine exfoliative cytology. Among the collected cases, there were also 1 100 pathological tissue controls. Results: The accuracy, sensitivity and specificity of the AI-assisted cytologic screening system were 77.18%, 90.79% and 69.49%; those of human-machine coordination method were 92.89%, 99.63% and 89.09%, respectively. Compared with the histopathological results, the accuracy, sensitivity and specificity of manual reading were 79.82%, 74.20% and 95.80%, respectively, while those of AI-assisted cytologic screening system were 93.45%, 93.73% and 92.66%, respectively. The accuracy, sensitivity and specificity of human-machine coordination method were 95.36%, 95.21% and 95.80%, respectively. Both cytological and histological controls showed that human-machine coordination review method had higher diagnostic accuracy and sensitivity, and lower false negative rates. Conclusions: The artificial intelligence TPS assisted cytologic screening system has achieved acceptable accuracy in urine exfoliation cytologic screening. The combination of manual screening and artificial intelligence TPS assisted screening system can effectively improve the sensitivity and accuracy of cytologic screening and reduce the risk of misdiagnosis.

OBJECTIVE: To analyze the genomic variation characteristics of fetal with abnormal serological screening, and to further explore the value of copy number variation (CNV) detection technology in prenatal diagnosis of fetal with abnormal serological screening. METHODS: 7617 singleton pregnant women who underwent amniocentesis for prenatal diagnosis solely due to abnormal Down's serological screening were selected. According to the results of serological screening, the patients were divided into high risk group, borderline risk group and single abnormal multiple of median (MOM) group. CMA and CNV-Seq were used to detect the copy number variation of amniotic fluid cell genomic DNA and combined with amniotic fluid cell karyotype analysis for prenatal diagnosis. Outpatient revisit combined with telephone inquiry was used for postnatal follow-up. RESULTS: Among 7617 amniotic fluid samples, aneuploidy was detected in 138cases (1.81%) by CMA and CNV-Seq, 9 cases of aneuploid chimerism were detected by amniotic fluid cell karyotype analysis, and 203 cases of fetus carrying pathogenic and likely pathogenic CNV (P/LP CNV) were detected, the variant of uncertain significance (VUS) was detected in 437 cases (5.7%), the overall abnormal detection rate was 10.33%. The detection rate of aneuploidy by CMA and CNV-Seq in three group were 123 cases (2.9%), 13 cases (1.3%) and 2 cases (0.4%), respectively,and showing no significant difference (χ ²=7.469, P=0.024). The detection rate of pathogenic and likely pathogenic CNV in three group were 163cases (2.6%); 24 cases (2.6%) and 16 cases (3.3%), respectively, and showing no significant difference (χ ²=0.764, P=0.682). The CMA reported 2.9% (108/3729)P/LP CNV, and CNV-seq reported 2.4% (95/3888)P/LP CNV, both tests showed similar detective capabilities (χ ²=1.504, P=0.22).The most popular P/LP CNV in this cohort were Xp22.31 microdeletion, 16p13.11 microduplication /microdeletion, 22q11.21 microduplication /microdeletion. In fetuses with P/LP CNV CNV, 59 fetuses were terminated pregnancy, and 32 of 112 fetuses born had abnormal clinical manifestations. Non-medically necessary termination of pregnancy occurred in 11 fetuses carrying VUS CNV, 322 fetuses carrying VUS CNV were born, 4 of them presented abnormal clinical manifestations. CONCLUSION Compared with the traditional chromosome karyotype, CMA and CNV-Seq can improve the detection rate of pathogenic and likely pathogenic CNV. CMA and CNV-seq can be used for first tier diagnosis of pregnant women in the general population with abnormal Down's serological screening.
