Infertility is an important cause of reproductive health. With the increasing development of assisted reproductive technology, millions of people choose to use assisted reproductive technology to assist pregnancy every year. However, there are still many patients in the clinic who may have fertilization disorders during the assisted pregnancy. The causes of fertilization disorders are complex and varied. Although research on fertilization disorders has progressed in recent years, the question of how to improve the fertilization rate and oocyte utilization in patients remains a focal issue. The aim of this review is to summarize the latest research progress on the possible etiology and treatment of fertilization disorders in the process of conception, so as to provide a more comprehensive theoretical reference for the clinical diagnosis and management of people with fertilization disorders.

Objective Analyze the causes of coding issues in the inpatient medical record homepage of a hospital and propose targeted improvement measures,providing a reference basis for enhancing coding quality.Methods A total of 3 000 in-patient medical records from April 1,2021,to March 31,2022(pre-intervention group)and 2 900 records from April 1,2022,to March 31,2023(post-intervention group)were selected for analysis.Quality control statistics were performed on key indica-tors,including the overall coding accuracy rate,primary diagnosis coding,secondary diagnosis coding,primary surgical proce-dure coding,and other surgical procedure coding.Results After the implementation of intervention measures,the overall accu-racy rate of the first page coding of medical records increased from 80.77％to 86.72％(P＜0.001).While,the accuracy rate for primary diagnosis coding improved from 96.90％to 98.07％(P＜0.05).The secondary diagnosis coding accuracy showed significant enhancement from 87.48％to 92.26％(P＜0.001),and primary surgical procedure coding accuracy rose from 96.50％to 98.34％(P＜0.001).Although other surgical procedure coding demonstrated improvement,the difference was not statistically significant(P＞0.05).Conclusion Through a series of measures—including standardized training for coders,es-tablishing a robust quality control system,and adopting advanced information technology—both the professionalism of coders and coding efficiency were enhanced.These interventions effectively reduced coding defects and improved the quality of medical re-cord homepage coding.

As a physical treatment technique, modified electro-convulsive therapy (MECT) is used to treat mental and certain neurological disorders by causing seizures with short, suitable electrical currents applied to the brain while the patient is under general anesthesia and muscle relaxants. MECT is recognized for its therapeutic efficacy and clinical safety, rendering it one of the most prevalent interventions in psychiatric care. To enhance clinical outcomes and minimize adverse effects, this consensus document delineates the indications, therapeutic parameters, therapeutic procedures, potential adverse effects, and associated management strategies for MECT. These guidelines are informed by the latest clinical research and expert consensus, integrating evidence-based medicine methodologies. The objective is to furnish clinicians with precise operational guidelines and to advance the standardization of MECT practices in clinical settings.

Langerhans cell sarcoma(LCS)is a rare malignant tumor derived from Langerhans cell histiocytes with unique clinicopathological,immunophenotypic,ultrastructural and molecular genetic features.Most studies on LCS are case reports,and the immunohistochemical features,biological mechanisms and molecular basis of the tumor remain to be further elucidated.A large body of literature suggests that LCS is extremely aggressive and presents many difficulties in clinical diagnosis,so it is important to accurately diagnose LCS.In this paper,we will review the clinical,patholog-ical and molecular features of LCS to provide more ideas for the definitive diagnosis of LCS and providing a basis for the selection of treatment regimens for LCS.

Elemental imaging analysis based on laser induced-breakdown spectroscopy(LIBS)can provide significant reference value for oil and gas exploration activities.Improving the scanning speed and spatial resolution of LIBS elemental imaging analysis instruments contributes to enhancing the efficiency of mineral surface elemental analysis,which is crucial for achieving in-situ,real-time,and rapid LIBS analysis.In this study,a high-speed scanning LIBS elemental imaging analysis instrument was developed based on a scanning mirror device,achieving a scanning speed of 100 Hz and a spatial resolution of 50 μm.The stability of spectral data collected by this instrument was validated using aluminum alloy standard samples with uniform elemental distribution.The experimental results showed that the relative standard deviations(RSD)of the spectral data collected at different locations were 2.76％,2.79％,2.35％and 2.55％,respectively,demonstrating that the instrument's performance met analysis requirements.Analysis of spectral acquisition channels led to the selection of the 337-595 nm spectral range.Imaging analysis of major elements on the surface of meteorite mineral samples with complex matrices was conducted using this instrument,coupled with a multi-element imaging algorithm enabling visualization analysis of four major elements on the same image.The results revealed a higher level of detail and complexity in element distribution.The study demonstrated that this instrument,combined with multi-element imaging analysis algorithms,could provide crucial technical support for rapid imaging of element distribution in minerals at a microscopic scale during geological research.
