[Purpose]To analyze the results of cervical cancer screening among married women of 25～64 years old in Shihezi City from 2021 to 2023,and to explore the risk factors of cervical le-sions.[Methods]The results of cervical cancer screening among married women aged 25～64 years old in Shihezi City from 2021 to 2023 were retrospectively analyzed.The detection rates of common gynecological diseases,cervical cancer and precancerous lesions and human papillo-mavirus(HPV)infection by cervical cytology,colposcopy and cervical biopsy were analyzed.[Re-sults]The HPV infection(mainly single infection)rate was 10.74％.The common gynecological diseases were vaginitis,cervicitis and uterine leiomyoma.The detection rate of cervical cancer was 19.59/105,and the detection rate of cervical precancerous lesions was 308.52/105.Rural resi-dents,HPV 16/18 infection,genital warts were the risk factors for cervical lesions.[Conclusion]Female cervical lesions are significantly correlated with HPV 16/18 infection,genital condyloma acuminatum,particularly for rural residents,and preventive care,early screening and interven-tion should be strengthened for these populations.

Uveitis-glaucoma-hyphema syndrome is a rare complication after intraocular lens (IOL) implantation.The cause of the disease is the mechanical friction of the intraocular lens on the anterior segment structures.There is no unified consensus on the pathogenesis of UGH syndrome, and it is generally accepted that disruption of the blood-aqueous humor barrier and reverse pupillary block are the two common mechanisms.The typical clinical manifestations of UGH syndrome include anterior chamber inflammation, increased intraocular pressure and hyphema, with or without vitreous hemorrhage.It is easily misdiagnosed as uveitis.If untreated, it can lead to serious consequences such as loss of vision.The diagnosis of UGH syndrome is based on IOL implantation history, slit-lamp microscopy examination (especially after pupil dilation) that observes an IOL deviation or absence of the capsule, and an ultrasound biomicroscopy that observes contact between IOL and the iris or ciliary body.Treatment for UGH syndrome includes drugs, lasers, and surgery.At present, surgery is the primary method, mainly including IOL alignment, IOL removal or replacement, capsular tension ring implantation, etc.Laser treatments include laser iridoplasty, laser iridotomy and ciliary body laser photocoagulation.UGH syndrome has been reported more frequently abroad and is only reported as case reports in China.The purpose of this review is to discuss the etiology, pathogenesis and diagnosis of UGH syndrome.In addition, we discuss the treatment and caveats of UGH syndrome.The aim of review is to provide a more comprehensive basis for clinicians to understand, diagnose and treat UGH syndrome.

Objective:To explore the relationship between the perceived stress and the independent learning ability of nursing undergraduates, to establish a chain mediation model to investigate the role of psychological capital and self-control in the relationship between the two, aiming to provide a new direction for nursing educators to improve the independent learning ability of nursing undergraduates.Methods:Using the convenient sampling method, a total of 913 nursing undergraduates from 10 universities in Shaanxi Province were selected as research objects from February to March 2023. Perceived Stress Scale (PSS), Positive Psychological Capital Questionnaire (PPQ), Self-control Scale (SCS) and Self-directed Learning Ability Scale (SLAS) were used to investigate the nursing undergraduates.Results:A total of 913 questionnaires were sent out in this study, and 900 were effectively collected, with an effective recovery rate of 98.58% (900/913). The total SLAS score of 900 nursing undergraduates was (87.12±9.20). The perception of stress among undergraduate nursing students could directly predict their self-directed learning ability negatively ( P<0.01), or indirectly affected their self-learning ability through psychological capital and self-control ( P<0.05). Psychological capital (indirect effect value=-0.160) and self-control (indirect effect value=-0.106) played a mediating role between stress perception and self-directed learning ability, and the mediating effect accounted for 38.55% and 25.54%, respectively. Moreover, psychological capital and self-control also played a chain mediating role (indirect effect value=-0.053), and the proportion of chain mediated effect was 12.77%. Conclusions:Perceived stress, psychological capital and self-control are important influencing factors on the self-directed learning ability of nursing undergraduate students. Perceived stress not only directly affects the self-directed learning ability of nursing undergraduate students, but also indirectly affects their self-directed learning ability through the chain mediation effect of psychological capital and self-control.

With the progression of research on extrachromosomal DNA(ecDNA),it has been shown that ecDNA exists mainly in tumor cells and plays a crucial role in tumor heterogeneity and drug resistance.ecDNA is observed in several cancer types,but rarely in normal cells.Due to their strong oncogene amplification and dynamic alteration capabilities,patients with ecDNA-containing tumor cells often have negative clinical prognoses.Research has confirmed the presence of ecDNA in the cancer cells of patients with small cell lung cancer(SCLC).This re-view provides a comprehensive summary of the formation mechanism of ecDNA,the processes through which it is amplified in cancer cells,the mechanisms through which ecDNA promotes tumor growth,recurrence,and metastasis,and its relationship with high drug resistance in SCLC.Finally,we generalize the treatment direction for ecDNA-enriched SCLCs,thereby guiding future research.

Objective To investigate the neurobehavioral development of young children aged 24 to 60 months in Shunde and explore the factors influencing the development of young children and provide reference for the interven-tion of neurobehavioral development delays in young children.Methods A retrospective cohort study was used to enroll the young children who were initially screened by the Pediatric Neuropsychological Developmental Scale(Pe-diatric Heart Scale)with a score of ≤85 was included in the study.With a score of ≤85,the young children might be at risk of developmental delays,and needed to be further diagnosed by the GESELL Developmental Diagnostic Scale,the basic information of the young children and their mothers at the time of birth were investigated,as well as basic information about the young children at the time of completing the GESELL Developmental Diagnostic Scale was collected.Results A total of 271 young children were included,196 males and 75 females.Young children had the lowest developmental quotient(DQ)in the language domain among the five domains(P＜0.001).Multiple lin-ear regression models showed:compared with girls,the language domain DQ of boys decreased by 5.321 points(P=0.049,95％CI:-10.620--0.021),and the personal-social domain DQ decreased by 4.474 points(P=0.023,95％CI:-8.316--0.631).Compared with young children via natural vaginal delivery(NVD),the gross motor domain DQ of young children via caesarean section(CS)decreased by 4.890 points(P=0.008,95％CI:-8.499--1.281),the fine motor domain DQ decreased by 3.373 points(P=0.037,95％CI:-6.532--0.213),the language domain DQ decreased by 7.621 points(P=0.004,95％CI:-12.826--2.416),per-sonal-social domain DQ decreased by 6.232 points(P=0.001,95％CI:-10.006--2.457).The results of bi-nary logistic regression models showed,compared with young children via NVD,the risk of gross motor domain retar-dation in young children increased(OR=1.763,95％CI:1.003-3.100),the risk of fine motor domain retardation increased(OR=2.217,95％CI:1.235-3.980),the risk of language domain retardation increased(OR=3.306,95％CI:1.080-10.124).Conclusion Young children with suspected neurobehavioral delays were more likely to have delayed development in language domain than in other domains,boys had lower DQ in language domain and personal-social domain than girls,and the development of young children via CS was slower than that via NVD.Fo-cus should be on the language development of young children especially on the language and personal-social devel-opment of boys.Carefully chose delivery way.Focus should be placed on assessment of young children's comprehen-sive neurobehavioral development in early time.

Polycystic ovary syndrome (PCOS) is one of the most common reproductive endocrine disorders in women of reproductive age, and its pathogenesis is not yet fully understood. Many studies have confirmed that programmed cell death (PCD) can affect the occurrence and development of PCOS, and regulating PCD may be the key to prevent and treat PCOS. Recent researches have revealed many non-coding RNA (ncRNA) related to epigenetics, including microRNA, long ncRNA, and circular RNA. Although these ncRNA do not directly serve as carriers of genetic information, they can activate various cellular response mechanisms by regulating the expression of related proteins and genes, such as apoptosis, autophagy, ferroptosis, necroptosis, and pyroptosis, thereby affecting granulosa cell development, disrupting endocrine homeostasis, participating in the pathological process of PCOS, and influencing its prognosis. This paper discusses the pathogenesis of PCOS through the regulation of PCD by ncRNA, aiming to provide new insights for the treatment of PCOS.

Metabolism is an important physiological activity throughout the cell life cycle, and energy substrates play an important role in regulating follicle development, maintaining sperm motility, influencing preimplantation embryo development and inducing immune tolerance at the maternal-fetal interface. Normal metabolism can promote cell growth and development, while abnormal metabolism can lead to dysfunction, and is closely related to the occurrence and development of diseases related to female reproduction. This study provides an overview of glucose metabolism, lipid metabolism and protein (amino acid) metabolism in the reproductive process and their relationship with several reproductive diseases. It is expected to optimize in vitro maturation of oocytes by regulating the energy metabolism, and provide new approaches for the study of energy metabolism at the maternal-fetal interface of embryo implantation and the diagnosis and treatment of infertility.
