Chronic fatigue syndrome (CFS) is a common problem in military maritime navigation, which greatly affects the safety of military missions. The use of animal models to carry out research on the mechanism of CFS and treatment measures is a common method. This paper systematically introduced the construction methods of CFS models such as single-factor and multi-factor models, summarized common evaluation indicators of CFS, including behavioral and biochemical indicators, and summed up key characteristics of CFS animal models in military oceanic navigation combined with common causes of CFS in military contexts, such as prolonged continuous work, high-intensity physical activity, sleep deprivation, psychological stress, and extreme environmental conditions. The key characteristics of the animal models included, but not limited to, chronic fatigue, sleep disorders, impaired cognitive function, psychological stress responses, and abnormal biochemical indicators. Furthermore, this article identified future research directions for CFS animal models in military oceanic navigation to enhance the application value of the models and provide robust support for the health protection and disease prevention of military personnel.

ObjectiveThis study aims to investigate the effects of Linggui Zhugantang (LGZGT) on ventricular remodeling (VR) in mice with myocardial infarction (MI) and its impact on the Ras homologgene A (RhoA)/Rho-associated coiled-coil forming protein kinase (ROCK) signaling pathway. MethodsThe MI model of mice was established by ligating the left anterior descending coronary artery (LAD). They were divided into the sham-operated group, the model group, the low-dose, medium-dose, and high-dose groups of LGZGT (2.34, 4.68, 9.36 g·kg-1), and the captopril group (3.25 mg·kg-1), with 10 mice in each group. After four weeks of continuous drug administration by gavage, the level of cardiac function in each group of mice was examined using small animal Doppler ultrasound. Hematoxylin-eosin (HE) staining and Masson staining was used to assess the morphological changes of myocardial tissue and calculate the rate of collagen fiber deposition in mouse myocardial tissue. Wheat germ agglutinin (WGA) staining was employed to compare the cross-sectional area of cardiomyocytes in each group of mice. The expression levels of α-smooth muscle actin (α-SMA), matrix metalloproteinase-2 (MMP-2), type Ⅰcollagen (Col Ⅰ), Col Ⅲ, tissue inhibitor of metalloproteinase 1(TIMP1), B-cell lymphoma-2 (Bcl-2)-associated X protein (Bax), Bcl-2, Caspase-3, and cleaved Caspase-3 were detected by Western blot. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to evaluate the mRNA levels of the pathway-related genes RhoA, ROCK1, and ROCK2. The protein expression levels of RhoA, ROCK1, and ROCK2 were tested by Western blot. ResultsThe level of cardiac function was markedly declined in the model group compared to the sham-operated group(P<0.01). Myocardial tissue morphology changed significantly. The cross-sectional area of cardiomyocytes was significantly enlarged. The expression of α-SMA, MMP-2, Col Ⅰ, and Col Ⅲ was significantly upregulated(P<0.01), and TIMP1 protein expression was significantly reduced(P<0.01). The expressions of apoptosis-related proteins Bax were significantly up-regulated(P<0.01), while the expression of Bcl-2 protein was significantly decreased(P<0.01). The mRNA expression of RhoA, ROCK1, and ROCK2 were significantly upregulated (P<0.01). Compared to the model group, the low-dose, medium-dose, and high-dose groups of LGZGT and the captopril group significantly reversed the experimental results of the model group in a dose-dependent manner (P<0.05, P<0.01). ConclusionLGZGT significantly attenuated myocardial fibrosis, myocardial hypertrophy, and cardiomyocyte apoptosis after MI in mice and effectively reversed VR, the mechanism of which may be related to the modulation of the RhoA/ROCK signaling pathway.

Based on the viewpoint of "sweat pore-qi and liquid-kidney collaterals", it is believed that children's nephrotic syndrome is caused by the core mechanism of sweat pore constraint and closure, qi and liquid imbalance, and kidney collaterals impairment, and it is proposed that the treatment principle is to nourish the sweat pore, regulate qi and fluid, and supplement the kidney and unblock the collaterals. In clinic, guided by sequential therapy and according to the different disease mechanism characteristics of the four stages, including early stage of the disease, hormone induction stage, hormone reduction stage, hormone maintenance stage, the staged dynamic identification and treatment was applied. For early stage of the disease with edema due to yang deficiency, modified Zhenwu Decoction (真武汤) was applied to warm yang and drain water; for hormone induction stage with yin deficiency resulting in effulgent fire, modified Zhibai Dihuang Pill (知柏地黄丸) plus Erzhi Pill (二至丸) was used to enrich yin and reduce fire; for hormone reduction stage with qi and yin deficiency, modified Shenqi Dihuang Decoction (参芪地黄汤) was used to boost qi and nourish yin; for hormone maintenance stage, modified Shenqi Pill (肾气丸) was used to supplement yin and yang. Meanwhile, the treatment also attaches importance to the combination of vine-based or worm medicinals to dredge collaterals, so as to providing ideas for clinical treatment.

Background:
Maturity-onset diabetes of the young (MODY) due to variants of hepatocyte nuclear factor 1-beta (HNF1β) (MODY5) has not been well studied in the Chinese population. This study aimed to estimate its prevalence and evaluate the application of a clinical screening method (Faguer score) in Chinese early-onset diabetes (EOD) patients.
Methods:
Among 679 EOD patients clinically diagnosed with type 2 diabetes mellitus (age at diagnosis ≤40 years), the exons of HNF1β were sequenced. Functional impact of rare variants was evaluated using a dual-luciferase reporter system. Faguer scores ≥8 prompted multiplex ligation-dependent probe amplification (MLPA) for large deletions. Pathogenicity of HNF1β variants was assessed following the American College of Medical Genetics and Genomics (ACMG) guidelines.
Results:
Two rare HNF1β missense mutations (E105K and G454R) were identified by sequencing in five patients, showing functional impact in vitro. Another patient was found to have a whole-gene deletion by MLPA in 22 patients with the Faguer score above 8. Following ACMG guidelines, six patients carrying pathogenic or likely pathogenic variant were diagnosed with MODY5. The estimated prevalence of MODY5 in Chinese EOD patients was approximately 0.9% or higher.
Conclusion
MODY5 is not uncommon in China. The Faguer score is helpful in deciding whether to perform MLPA analysis on patients with negative sequencing results.
