Patients with alcoholic cirrhosis often experience varying degrees of malnutrition， and the patients with malnutrition are more susceptible to complications such as infections and ascites， which may lead to a poor prognosis. Therefore， it is particularly important to conduct nutritional risk screening for patients in clinical practice， and appropriate nutritional assessment tools should be used to evaluate the nutritional status of patients and develop individualized nutritional supplementation regimens， thereby promoting disease recovery and improving prognosis and quality of life. This article elaborates on the specific methods for nutritional screening， assessment， and management in patients with alcoholic cirrhosis and points out that systematic nutritional screening and assessment can help to identify the patients with malnutrition in the early stage and provide timely intervention. Individualized nutritional supplementation regimens should be adjusted based on the conditions of patients， so as to meet their nutritional needs， promote the recovery of liver function， improve overall health status， and enhance long-term quality of life.

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.

Objective To assess the clinical value of multimodal ultrasound score for assessment of endometrial receptivity among patients with polycystic ovary syndrome (PCOS), and to provide guidance for improving pregnancy outcomes among PCOS patients. Methods A total of 48 PCOS patients admitted to Jiangning Hospital Affiliated to Nanjing Medical University between January and December 2023 were enrolled as the case group, while 50 healthy women of childbearing age received ovulation monitoring at the same hospital during the same period served as the control group. Subjects received two-dimensional grayscale ultrasound during the implantation window (19 to 23 days of the menstrual cycle) for measurement of endometrial thickness, Gonen classification, and endometrial peristalsis. Two-dimensional color Doppler ultrasound was used for assessment of endometrial blood flow and three-dimensional ultrasound was used for assessment of endometrial volume and vascularization flow index (VFI). The endometrium multimodal ultrasound scores were estimated, and various parameters were compared between the two groups. The diagnostic performance of these parameters for PCOS was evaluated with receiver operating characteristic (ROC) curves. Results The age of subjects in the case group ranged from 20 to 38 years, with a mean age of (28.20 ± 2.82) years, and their body mass index (BMI) ranged from 21.23 to 29.11 kg/m², with a mean BMI of (26.25 ± 1.60) kg/m². The age of subjects in the control group ranged from 22 to 38 years, with a mean age of (28.10 ± 1.99) years, and their BMI ranged from 21.33 to 29.03 kg/m², with a mean BMI of (26.10 ± 1.78) kg/m². There were no significant differences between the case and control groups in terms of mean age, BMI, estradiol, and testosterone (t = 0.218, 0.422, 0.010, and 0.221; all P > 0.05). The endometrial thickness, endometrial volume, and VFI were significantly higher in the control group than in the case group (t = 4.838, 4.978, and 7.115; all P < 0.05). There were significant differences between the two groups in terms of endometrial classification, endometrial peristalsis pattern, and endometrial and sub-endometrial blood flow (Z = −4.136, −4.048, and −3.884; all P < 0.05). The scores of endometrial classification, endometrial peristalsis, endometrial and sub-endometrial blood flow, endometrial volume, VFI, and multimodal ultrasound were significantly lower in the case group than in the control group (t = 4.539, 4.449, 4.205, 3.209, 5.206, and 4.495; all P < 0.05). No significant difference was detected in the endometrial thickness score between the two groups (t = -0.149, P = 0.882). The areas under the ROC curves for endometrial thickness, endometrial volume, VFI, and multimodal ultrasound scores in diagnosis of PCOS were 0.753, 0.747, 0.809, and 0.858, respectively. Conclusion Multimodal ultrasound score provides a comprehensive assessment of the endometrium, and is effective in the assessment of endometrial receptivity, which may provide a reference for guiding pregnancy planning in PCOS patients.

Objective: To compare the changes in the concentration of relevant growth factors released from platelet-rich plasma (PRP) stored at -80℃ by cryopreservation and at 4℃ by refrigerated lyophilization over 2 years, aiming to provide a theoretical basis for prolonging PRP storage duration. Methods: PRP (n=15) was separated using a blood cell separator and stored under -80℃ cryopreservation (F-PRP group) and 4℃ refrigerated freeze-drying conditions (FD-PRP group). The contents of growth factors (PDGF-AA, PDGF-BB, EGF, TGF-β1, and VEGF) in both groups were measured by ELISA at 1, 3, 6, 9, 12 and 24 months. Results: PDGF-AA and VEGF maintained good stability in both groups for up to 24 months. PDGF-BB and TGF-β1 showed high stability in the first 12 months but their stability decreased gradually from 12th to 24th months. EGF demonstrated good stability in the first 6 months, and its stability gradually decreased from the 9th to 24th months. Comparing the F-PRP and FD-PRP groups, the concentrations of the five growth factors in the FD-PRP group were either not statistically different or higher than those in the F-PRP group at all time points. Specifically, the concentrations of EGF were significantly higher in the FD-PRP group at all time points. Conclusion: Both -80℃ freezing and 4℃ freeze-drying enable long-term preservation of PRP. Freeze-drying imposes less stringent storage requirements and facilitates growth factor compared to frozen storage.

Objective: This study aimed to construct an animal model of heart failure with preserved ejection fraction (HFpEF) that integrates disease and syndrome based on the "deficiency-blood stasis-toxin" pathogenesis and to evaluate it comprehensively. Methods: The HFpEF mouse model was constructed using a combination of Nω-nitro-L-arginine methyl ester (L-NAME) and a high-fat diet. According to the random number table method, SPF-grade male C57BL/6J mice were randomly assigned to the control, L-NAME, high-fat diet, and model groups, 10 in each group. Comprehensive observations and data collection on macroscopic signs (e.g., fur condition, mental state, stool and urine, oral and nasal condition, paw and body condition, etc.) and cardiac function were performed after 10 and 16 weeks of model induction. Additionally, the syndrome evolution was elucidated based on diagnostic criteria for clinical syndromes of heart failure. Furthermore, pathological and molecular biological examinations of myocardial tissue were performed to assess the stability and reliability of the model. Results: Mice in the model group showed typical characteristics of syndrome of qi deficiency and blood stasis, as well as syndrome of internal heat accumulation, including lethargy, slow response, dull paw color and oral/nasal color, exercise intolerance, abnormal platelet activation, dry feces, and dark yellow urine. The time window for these syndromes was between 10 and 16 weeks post-modeling. Cardiac function assessments revealed severe diastolic dysfunction, concentric myocardial hypertrophy, and myocardial fibrosis in the model group. Pathological examinations showed a significantly increased collagen deposition in the myocardial interstitium, enlarged cross-sectional area of cardiomyocytes, and sparse coronary microvasculature in the model group. Molecular biological analyses indicated marked activation of the inducible nitric oxide synthase/nuclear factor kappa-light-chain-enhancer of activated B cells/NOD-like receptor family pyrin domain containing 3 inflammatory pathway and significantly elevated inflammation levels in the myocardial tissue of the model group. Although mice in the L-NAME and high-fat diet groups also showed certain manifestations of qi deficiency syndrome, the substantial cardiac damage was relatively limited compared to the control group. Conclusion This study has constructed an animal model of HFpEF that integrates disease and syndrome based on the "deficiency-blood stasis-toxin" pathogenesis. The macroscopic and microscopic characteristics of this model are consistent with the manifestations of syndrome of qi deficiency and blood stasis, toxin syndrome, and syndrome of internal heat accumulation. Moreover, it can stably simulate the HFpEF state and reflect phenotypic changes in human disease. This model provides a suitable experimental platform to explore the pathogenesis of HFpEF, evaluate the effectiveness of traditional Chinese medicine (TCM) treatment regimens, and promote in-depth research on TCM syndromes of heart failure.

Primary ciliary dyskinesia (PCD) is a clinically rare, genetically and phenotypically heterogeneous condition characterized by chronic respiratory tract infections, male infertility, tympanitis, and laterality abnormalities. PCD is typically resulted from variants in genes encoding assembly or structural proteins that are indispensable for the movement of motile cilia. Here, we identified a novel nonsense mutation, c.466G>T, in cilia- and flagella-associated protein 300 ( CFAP300 ) resulting in a stop codon (p.Glu156*) through whole-exome sequencing (WES). The proband had a PCD phenotype with laterality defects and immotile sperm flagella displaying a combined loss of the inner dynein arm (IDA) and outer dynein arm (ODA). Bioinformatic programs predicted that the mutation is deleterious. Successful pregnancy was achieved through intracytoplasmic sperm injection (ICSI). Our results expand the spectrum of CFAP300 variants in PCD and provide reproductive guidance for infertile couples suffering from PCD caused by them.

OBJECTIVES: To study the significance of serum 25-hydroxyvitamin D₃ [25-(OH)D₃] level in the clinicopathological characteristics and prognosis of children with immunoglobulin A vasculitis nephritis (IgAVN). METHODS: A retrospective analysis was conducted on the clinical data of children with IgAVN who underwent renal biopsy at Suzhou Hospital Affiliated to Anhui Medical University and Jinling Hospital of the Medical School of Nanjing University from June 2015 to June 2020. Based on serum 25-(OH)D₃ level, the patients were divided into a normal group and a lower group. The clinicopathological characteristics and follow-up data of the two groups were collected and compared. RESULTS: A total of 359 children with IgAVN were included. Compared to the normal group (62 cases), the lower group (297 cases) exhibited higher incidences of hematochezia and gross hematuria, higher levels of serum creatinine, blood urea nitrogen, urinary retinol protein, urinary N-acetyl-β-D-glucosaminidase, and quantitative urinary protein, and a longer duration from renal biopsy to urinary protein becoming negative, as well as lower estimated glomerular filtration rate and albumin level (P<0.05). Renal pathology in the lower group showed a higher occurrence of tubular interstitial injury, crescent formation, segmental sclerosis in glomeruli, and inflammatory cell infiltration in the renal interstitium compared to the normal group (P<0.05). Survival analysis indicated that the cumulative renal survival rate was lower in the lower group (P<0.05). Multivariate Cox regression analysis revealed that low serum 25-(OH)D₃ level is an independent risk factor for poor prognosis in children with IgAVN. CONCLUSIONS Children with IgAVN and low serum 25-(OH)D₃ level have relatively severe clinicopathological manifestations. Low serum 25-(OH)D₃ level is an independent risk factor for poor prognosis in children with IgAVN.

Miao medicine is guided by the medical theories of the Miao ethnic group, and the drugs used by the Miao people are derived from natural plants and animals for the prevention and treatment of diseases and protection of health. In recent years, a large number of clinical studies have shown good clinical efficacy of traditional Miao medicine in the treatment of prostatic diseases, with the advantages of easy availability, low price, and minimal adverse reactions. However, currently no systematic literature review has been reported on the treatment of prostatic diseases with Miao medicine. This article focuses on the commonly used Miao drugs recorded in the Chinese Materia Medica－Miao Medicine, with a systematic review of relevant literature retrieved on the treatment of prostate diseases with Miao medicine in recent years and a summarization of the advances in the studies of its pharmacological effects, mechanisms of action and clinical application, aiming to provide some new perspectives and ideas for further academic research and clinical development of Miao medicine.
