Obesity, as a chronic recurrent disease, has become a major public health challenge in China. To implement the requirements of the Healthy China Initiative (2019—2030), under domestic guidelines or consensus statements on overweight and obesity, and in alignment with the latest scientific advances globally, the Quality control protocol for adult overweight and obesity screening in health management (examination) institutions (2025 edition) was developed. This protocol was drafted by the Health Management Center of Shanghai Changzheng Hospital and formulated through multiple rounds of deliberation by experts in China’s health examination quality control field. The protocol establishes unified standards for screening facilities, personnel qualifications, and measurement or testing procedures. It defines specific screening items, outlines a standardized screening pathway, and sets requirements for the final medical review, ensuring the scientific validity, effectiveness, and safety of the screening process. The implementation of this protocol will enhance the consistency of weight management practices for adults across health examination institutions and strengthen the quality control of overweight and obesity screening programs.

Objective:To construct a multilevel nursing featured case bank, and to explore the effect of the case bank in clinical teaching of professional postgraduate nursing students, and to provide new ideas for teaching reform.Methods:Sixty professional postgraduate nursing students who interned in the First Affiliated Hospital of Nanchang University from May to September 2022 and from May to September 2023 were selected. The 30 professional postgraduate nursing students who interned from May to September 2022 were included in the control group, and the 30 professional postgraduate nursing students who interned from May to September 2023 were included in the intervention group. The control group was taught by the teaching teacher using the traditional teaching courseware of the internship department and instructed by the teaching teacher for taking care of the real patients and writing nursing records. The intervention group employed the multilevel nursing featured case bank for teaching on this basis. The autonomous learning ability and critical thinking ability were compared between the two groups before and after 2 months of intervention, respectively, and the satisfaction to the case bank was evaluated. The SPSS 25.0 statistical software was used for t-test and chi-square test. Results:After 2 months of teaching, the autonomous learning ability and critical thinking ability scores were (104.50±7.20) points and (283.73±19.42) points in the control group and (113.27±4.90) points and (304.60±13.40) points in the intervention group, and the differences between the two groups were statistically significant ( P<0.05). Twenty-seven (90.00%) students were satisfied with the multilevel nursing featured case bank. Conclusions:Application of the multilevel nursing featured case bank to clinical teaching can effectively improve the autonomous learning ability and critical thinking ability of professional postgraduate nursing students. It is an effective way to cultivate professional postgraduate nursing students.

OBJECTIVE To investigate a suspected outbreak of carbapenem-resistant Klebsiella pneumoniae(CRKP)infection in the intensive care unit of a traditional Chinese medicine hospital,identify the source of infec-tion and transmission routes,and provide a basis for prevention and control of CRKP infection.METHODS Epide-miological investigations were conducted on five patients with CRKP infections or colonization who were identi-fied in Jul.2024 at Suiyang County Hospital of Traditional Chinese Medicine.Samples were collected from pa-tients,the ward environments,and hand surfaces to detect CRKP.Fourteen CRKP isolates were selected for car-bapenemase gene testing,and homology analysis was performed by enterobacterial repetitive intergenic consensus polymerase chain reaction(ERIC-PCR)and multilocus sequence typing(MLST).RESULTS The median age of the five cases was 73 years,and all had undergone multiple invasive procedures.Environmental monitoring showed a CRKP positive rate of 26.35％,with CRKP isolates detected on the hands of healthcare workers,surfaces in the wards and medical equipment surfaces.Genetic analysis showed that all 14 CRKP strains carried the KPC resist-ance gene;except for case 1,other strains carried the VIM gene.MLST identified CRKP of all strains as sequence type 48(ST48);while ERIC-PCR revealed two distinct genotypes:genotype A for case 1 and genotype B for the other cases and environmental isolates.After strengthening patient isolation and group treatment,strictly cleaning and disinfecting the ward environments and medical equipment,and strictly implementing hand hygiene,the infec-tion was effectively controlled.CONCLUSIONS Inadequate disinfection of the ward environments and medical e-quipment and poor compliance with hand hygiene are the main contributors to the suspected CRKP outbreak.Ho-mology analysis suggests the existence of two independent transmission chains.Timely identification and manage-ment of the infection sources,interruption of transmission routes,protection of susceptible individuals and imple-mentation of comprehensive infection control measures are essential for effective outbreak control.

Keratoconus is a blinding eye disease characterized by central or paracentral corneal thinning, forward conical protrusion, and high myopia with irregular astigmatism.There are still no effective radical treatments for keratoconus.Current methods mainly include the prevention and treatment of risk factors, non-surgical optical correction and surgical treatment.The main risk factor prevention and treatment measures include intervention of eye rubbing behavior, symptomatic treatment of allergic diseases and systemic diseases, and correction of poor sleeping position.Non-surgical optical correction uses spectacles or corneal/scleral contact lenses to improve corrected vision.Surgical treatments include intracorneal ring segment implantation to improve corrected vision, corneal collagen cross-linking to increase the biomechanical stiffness of the cornea, and corneal transplantation to treat patients with severe keratoconus or corneal scarring.In addition, femtosecond laser-assisted keratoplasty, lenticule intrastromal keratoplasty combined with corneal collagen cross-linking have been gradually applied in clinical treatment, and tissue engineering based on biosynthetic substitutes, 3D bioprinting technology and cell engineering based on stem cell therapy have provided research prospects for the treatment of keratoconus.This article summarizes the prevention and treatment of clinical risk factors, non-surgical optical correction and surgical treatment, and discusses the research perspective of innovative treatment, in order to provide personalized treatment for patients with keratoconus.

Keratoconus is a blinding corneal disease characterized by central or paracentral corneal thinning and conical ectasia, and usually happens in adolescence. Currently, the etiology of keratoconus is unclear. Multiple studies have identified an association between genetics, eye rubbing, allergic diseases, ultraviolet exposure and keratoconus. Recently, several studies identified that sex hormones also played important roles in the pathogenesis of keratoconus. The disturbance of sex hormones may increase the risk of occurrence and progress of keratoconus. This review aims to summarize the pathophysiological effects of sex hormones on the cornea, clarify the effects of sex hormones on keratoconus and its related inflammatory or immune mechanisms, and explore the role of sex hormones in the early diagnosis and treatment of keratoconus, providing reference and help for clinical work.

Keratoconus is a progressive blinding eye disease that characterized by corneal thinning and protrusion, which accompanied with irregular astigmatism and impaired visual acuity.The irregular astigmatism of early keratoconus can be corrected by spectacles. For the irregular astigmatism of moderate to severe keratoconus, spectacles are no longer suitable, and contact lenses are the best choice for patients to restore vision. There are various types of contact lenses, making the selection very difficult. In addition, trying on lenses for a long time will increase the discomfort and overall feeling of patients, and greatly increase the workload of doctors. Thus, the article aims to summarize and discuss the classification of contact lenses, the application of contact lenses in different types of keratoconus, the complications of contact lens, and the current status and prospect of contact lenses, with a view to understanding the management and clinical application of contact lenses in keratoconus patients and to further improving the application value of contact lenses in keratoconus.
