ObjectiveTo explore the effects of Jingui Shenqiwan （JSW） and Liuwei Dihuangwan （LDW） on the reproductive ability and brain function of normal mice and compare the actions of the two medications. MethodsSeven groups of female and male mice were divided at a ratio of 2∶1. Except for the control group， the other six groups were as follows： a group of both males and females receiving JSW （3.0 g·kg^-1）， a group of both males and females receiving LDW （4.5 g·kg^-1）， a group of males receiving water and females receiving JSW， a group of males receiving water while females receiving LDW， a group of females receiving water while males receiving JSW， and a group of females receiving water while males receiving LDW. Each group was administered the drug for 14 days and then caged together at a 2∶1 （female∶male） ratio to detect the number of pregnant mice and calculate the pregnancy rate. Pregnant mice continued receiving the drug until they naturally gave birth， which was followed by the observation of newborn mice， calculation of their average number， and the measurement of the offspring's preference for sugar water and neonatal recognition index. At the end of the experiment， the weights of the thymus and spleen were measured to calculate the organ coefficients， and mRNA or protein expression was analyzed in the brain and testes or ovaries. A 1% sucrose solution was used to examine the euphoria of their brain reward systems， while novel object recognition test （NOR） was applied to assess their memory capabilities. mRNA expression was detected using real-time quantitative polymerase chain reaction （Real-time PCR） assay， and protein expression was analyzed with Western blot. ResultsCompared with the control group， oral administration of JSW to both male and female mice for 14 days significantly increased the pregnancy rate of female mice on day 2 after being caged together （P<0.05）， while LDW showed a trend but no statistical significance. Additionally， compared with the control group， JSW could upregulate the gene expression of gonadotropin-releasing hormone （GnRH） in the thalamus， as well as reproductive stem cell factor （SCF） and tyrosine kinase receptor （c-Kit） in the testes and reproductive stem cell marker mouse vasa homologue （MVH） in the ovaries， upregulate the expression of proteins influencing neuronal functional activity， such as brain-derived neurotrophic factor （BDNF）， in hippocampal neurons （P<0.05）， and enhance sucrose preference in male mice （P<0.05）. Compared with the control group， JSW significantly increased sucrose preference and novel object recognition index in offspring mice （P<0.05）， which was related to the upregulation of hippocampal dopamine D1 receptor （D1R） and N-methyl-D-aspartate receptor （Nmdar） gene expression. Compared with the control group， both JSW and LDW could upregulate the protein expression of glucocorticoid receptor （GR）， BDNF， and tyrosine kinase receptor B （TrkB） in the hippocampus of offspring mice （P<0.05）. ConclusionJSW significantly enhances the reproductive ability of normal mice， which is not only related to the release of gonadotropin but also associated with its regulation of brain function. Additionally， JSW has a certain regulatory effect on the brain function of the offspring mice.

Objective:To investigate the distribution of CGG repeat numbers in the FMR1 gene among reproductive-age women in China, providing data reference for carrier screening and genetic counseling of Fragile X syndrome. Methods:This cross-sectional study recruited 16 610 reproductive-age women from 12 medical institutions between July 2022 and October 2023. Peripheral venous blood samples (3 mL) were collected, and genomic DNA was extracted. The number of CGG repeats in the FMR1 gene was determined using the triplet-primed polymerase chain reaction (TP-PCR) combined with capillary electrophoresis technology. Statistical analyses were performed to assess the prevalence and distribution of CGG repeat expansions. Results:Among 16 610 women of childbearing age, 5 684 (34.220%) women had the same number of CGG repeats in the two alleles of FMR1 gene, and 10 926 (65.780%) women had different numbers of repeats in the two alleles. Among the 33 220 FMR1 alleles in 16 610 women of reproductive age, the most common CGG repeat numbers were 29 [48.645% (16 160/33 220)] and 30 [26.276% (8 729/33 220)], while the most frequent CGG genotype was CGG 29/29 [24.726% (4 107/16 610)]. The CGG repeat numbers of FMR1 gene were normal in 16 498 women (99.326%). Among the 112 women (0.674%) with CGG repeat abnormities, 96 (0.578%) women were classified as intermediate carriers, 15 (0.090%) as premutation carriers, and 1 (0.006%) as a full mutation carrier, whose CGG genotype was (36, >200). Conclusion:In the general reproductive-age female population in China, the normal CGG repeat numbers of the FMR1 gene account for 99.326%, while the intermediate carrier rate is 0.578%, and the combined carrier rate of the premutation and full mutation types is 0.096%.

Percutaneous coronary intervention(PCI)has been widely applied in the clinical treat-ment of coronary atherosclerotic heart disease and achieved good therapeutic effects.However,vascu-lar restenosis caused by postoperative vascular re-modeling still needs attention,which seriously af-fects the long-term efficacy of PCI.The prevention of vascular restenosis is of great significance for cardiovascular diseases.Traditional Chinese medi-cine natural products,with their characteristics of multiple targets,low toxicity and high safety,have attracted increasing attention in recent years.More and more studies have found that traditional Chi-nese medicine natural products have the effect of preventing and treating vascular restenosis and can effectively control its occurrence and development.This article reviews the effects and mechanisms of flavonoids,alkaloids,terpenoids and glycosides,polysaccharides and polyphenols and other tradi-tional Chinese medicine natural products in pre-venting vascular restenosis,and analyzes and sum-marizes the differences in the effects and mecha-nisms of various natural products,providing new ideas for the development of safe and effective drugs to prevent vascular restenosis.

Objective To compare the blood flow perfusion area in different retinal vascular plexuses between adults and children using swept-source optical coherence tomography angiography(SS-OCTA)and explore the correlation of the retinal blood flow perfusion area with spherical equivalent(SE)and axial length(AL).Methods A total of 112 partici-pants,including 58 children(116 eyes,aged 8-13 years)and 54 adults(108 eyes,aged 18-30 years),were recruited from Eye Hospital,Wenzhou Medical University from December 2020 to December 2024.Based on SE,these children and adults were further divided into the emmetropia(-0.50＜SE ≤+0.50 D),low myopia(-3.00＜SE≤-0.50 D),and moderate myopia(-6.00＜SE≤-3.00 D)groups.SS-OCTA was used to acquire the perfusion area data across retinal vascular layers.The inner vascular network of the retina was subdivided into the peripapillary radial vascular network,su-perficial vascular plexus(SVP),middle vascular plexus(MVP),and deep vascular plexus(DVP).The blood flow perfu-sion areas across retinal vascular layers were compared between adults and children.Pearson correlation analysis was per-formed to assess the correlation of the blood flow perfusion areas across retinal vascular layers with AL and SE in adults and children,respectively.Results SE was negatively correlated with AL in both adults and children(r=-0.781 and-0.667,respectively;both P＜0.001).The total inner retinal perfusion area was negatively correlated with AL in both adults and children(r=-0.239 and-0.299,respectively;both P＜0.05).In children,the perfusion area in the peripapil-lary radial vascular network,SVP,and DVP was negatively correlated with AL(r=-0.443,-0.315,and-0.220,respec-tively;all P＜0.05).In adults,the perfusion area in SVP,MVP,and DVP was negatively correlated with AL(r=-0.243,-0.230,and-0.364,respectively;all P＜0.05).Adults with low/moderate myopia exhibited a significantly larger perfu-sion area in the peripapillary radial vascular network compared with children with corresponding myopia levels,and the differences were statistically significant(both P＜0.001).Conclusion There were significant differences in the perfu-sion area of the peripapillary radial vascular network between adult and pediatric myopic patients.AL showed the strongest correlations with the perfusion area of the peripapillary radial vascular network in adults and the perfusion area of DVP in children,respectively,suggesting distinct effects of retinal vascular layers at different stages of ocular growth.

Objective:To formulate the audit standards of Chinese patent medicine prescriptions, and provide reference for rational prescriptions of Chinese patent medicine.Methods:A three-level evidence system for prescription review of Chinese patent medicine was established according to the national regulatory documents, drug labels, relevant guidelines, and expert consensuses. The catalog of Chinese patent medicines in Army Medical Center of the People′s Liberation Army was integrated and classified, preliminary review criteria including indications, drug selection, usage and dosage, and combination drugs was established and submitted to clinical experts of traditional Chinese medicine for review and revision, and finally the prescription review standard was confirmed.Results:The Chinese patent medicine catalog of the Medical Center contained 218 drugs, which were divided into 23 kinds according to efficacy and 17 kinds according to dosage forms. The prescription review standards of Chinese patent medicine were as follows. (1) Indications: both traditional Chinese medicine and Western medicine diagnosis were required.

The Cronbach's α coefficient of the Chinese version of the ICU Nurse Pressure Injury Prevention and Care Knowledge Questionnaire was 0.91. The questionnaire's overall difficulty and discrimination indexes were 0.67 and 0.59, respectively.Conclusions:The Chinese version of the ICU Nurse Pressure Injury Prevention and Care Knowledge Questionnaire has appropriate difficulty, moderate discrimination, and strong reliability, making it a valuable tool for assessing ICU nurses' knowledge of pressure injury-related topics.

Objective:To develop a treatment-related quality of life scale for Chinese patients with multiple myeloma (MM) and to test its reliability and validity.Methods:The initial scale was constructed through a literature search, Delphi expert correspondence, and cognitive testing. This study conducted a preliminary survey of 379 patients with MM and a formal survey of 865 patients from the hematology departments of 155 hospitals nationwide from February 2024 to March 2024. The final scale was obtained after conducting item analysis and reliability and validity tests on the initial scale.Results:The constructed scale contains 36 items covering six domains: physiological, psychological, social, treatment side effects, general health, and others. In the preliminary survey, the Cronbach’s alpha coefficient of each item ranged from 0.597 to 0.939, and the test-retest reliability was 0.747 ( P<0.001). Exploratory factor analysis extracted eight common factors with a cumulative variance contribution of 60.058%. In the formal survey, the Cronbach’s alpha coefficient of each item ranged from 0.484 to 0.930, and the test-retest reliability was 0.835 ( P<0.001). Confirmatory factor analysis revealed a comparative fit index of 0.750, a root-mean-square error of approximation of 0.090, and a root-mean-square residual of 0.067. Conclusion:The treatment-related quality of life scale for Chinese patients with MM designed in this study exhibited good reliability and validity, reflecting the impact of treatment on the quality of life of patients. This scale can provide a reference to clinicians for assessing the disease status of patients.
