ObjectiveTo observe the clinical efficacy of tonifying kidney and replenishing essence on asthenozoospermia patients with the syndrome of kidney essence deficiency and the effects of this method on the adenosine 5′-monophosphate-activated protein kinase (AMPK)/mammalian target of rapamycin complex 1 (mTORC1) signaling pathway. MethodsSeventy-two eligible asthenozoospermia patients with the syndrome of kidney essence deficiency treated in the Affiliated Hospital of Chengdu University of Traditional Chinese Medicine from February 2023 to January 2024 were selected and randomly assigned into an observation group and a control group, with 36 patients in each group. The observation group received oral administration of Guilu Tianjing capsules, while the control group received oral administration of L-carnitine oral solution. The treatment course lasted for 4 weeks in both groups. The observed indicators included sperm progressive motility rate (PR), total sperm motility (PR+NP), percentage of normal mitochondrial membrane potential (MMP), and traditional Chinese medicine (TCM) symptom scores before and after treatment in both groups. A three-month follow-up was instituted to record the conception status of the patients’ spouses. Additionally, eight patients were randomly selected from the eligible patients in the observation group, and four healthy males with normal semen routine examination results were included as the control group for the determination of protein expression. Western blotting was conducted to assess the expression of AMPK, phosphorylated (p)-AMPK, regulatory-associated protein of mTOR (RAPTOR) and p-RAPTOR, and PTEN-induced putative kinase 1 (PINK1) in sperms from the observation group before and after treatment, as well as in the sperms of the control group. ResultsThe pregnancy rate of spouses in the observation group was 9.09% (3/33), which was higher than that (3.33%, 1/30) in the control group. The total response rate was 84.8% (28/33) in the observation group and 66.7% (20/30) in the control group, with no statistically significant difference. After treatment, both groups were improved considering PR, PR+NP, MMP, and TCM symptom scores (P<0.01). Moreover, the observation group exhibited more pronounced decreases in TCM symptom scores than the control group (P<0.05), while the changes in PR, PR+NP, and MMP showed no statistical significance between groups. Compared with the control group, the asthenozoospermia group exhibited upregulations in phosphorylation levels of AMPK and RAPTOR and protein level of PINK (P<0.01). The administration of Guilu Tianjing Capsules led to downregulations in the phosphorylation levels of AMPK and RAPTOR and protein level of PINK1 (P<0.01). However, the protein levels of AMPK and RAPTOR demonstrated no significant difference between before and after treatment. During the study period, neither group of patients exhibited any notable adverse reactions. ConclusionGuilu Tianjing capsules can enhance the sperm motility and percentage of normal mitochondrial membrane potential in asthenozoospermia patients with the syndrome of kidney essence deficiency by downregulating the AMPK/mTORC1 signaling pathway, lowering the protein level of PINK1, and inhibiting excessive activation of mitophagy.

ObjectiveTo investigate the effect of laminin subunit α3 (LAMA3) on the epithelial-mesenchymal transition (EMT), invasion, and metastasis abilities of pancreatic cancer (PC). MethodsA comprehensive analysis was performed for tumor- and EMT-related databases to identify the EMT genes associated with PC, especially LAMA3. The methods of qRT-PCR and Western blot were used to measure the expression level of LAMA3 in PC tissue and cell lines; immunofluorescence assay was used to determine the localization of LAMA3 in PANC-1 cells; Transwell assay was used to investigate the effect of LAMA3 on the invasion and migration abilities of PC cells. The t-test was used for comparison of continuous data between groups. ResultsThe analysis of the TCGA database identified 3 EMT-related oncogenes for PC, i.e., LAMA3, AREG, and SDC1. The LASSO-Cox regression model showed that LAMA3 had the most significant impact on the prognosis of PC (risk score=0.256 1×LAMA3+0.043 1×SDC1+0.071 4×AREG). The Cox model and nomogram showed that the high expression of LAMA3 was an independent risk factor for the poor prognosis of PC (hazard ratio=1.32, 95% confidence interval: 1.07 — 1.62, P<0.01). Experimental results showed that there was a significant increase in the expression of LAMA3 in pancreatic cancer tissue compared with the normal pancreatic tissue. Compared with the HPDE cell line, there were varying degrees of increase in the expression of LAMA3 in pancreatic cancer AsPC-1, BxPC-3, PANC-1, MIA PaCa-2, and SW1990 cell lines, with the highest expression level in PANC-1 cells. The enrichment analysis showed that LAMA3 was associated with the biological processes and signaling pathways such as EMT, collagen metabolism, extracellular matrix degradation, the TGF-β pathway, and the PI3K pathway. After the knockdown of LAMA3, there were significant reductions in the expression levels of N-Cadherin, Vimentin, and Snail, while there was a significant increase in the expression level of E-Cadherin. Transwell assay showed that there were significant reductions in the invasion and migration abilities of PANC-1 cells after the knockdown of LAMA3. ConclusionLAMA3 is highly expressed in PC and can promote the EMT, invasion, and migration of PC cells, and therefore, LAMA3 may be used as a novel diagnostic marker and a new therapeutic target for PC.

[Objective] To analyze the loss rate of platelet donors and evaluate the strategies for establishing a platelet donor bank. [Methods] A total of 1 443 donors who joined the HLA and HPA gene donor bank for platelets in Henan Province from 2018 to 2020 were included in this study. Data on the total number of apheresis platelet donations, annual donation frequency, age at enrollment, donation habits (including the number of platelets donated per session and whether they had previously donated whole blood), and enrollment location were collected from the platelet donor information management system. Donor loss was determined based on the date of their last donation. The loss rates of different groups under various conditions were compared to assess the enrollment strategies. [Results] By the time the platelet bank was officially operational in 2022, 421 donors had been lost, resulting in an loss rate of 29% (421/1 443). By the end of 2023, the overall cumulative loss rate reached 52% (746/1 443). The loss rate was lower than the overall level in groups meeting any of the following conditions: total apheresis platelet donations exceeding 50, annual donation frequency of 10 or more, age at enrollment of 40 years or older, donation of more than a single therapeutic dose per session, or a history of whole blood donation two or more times. Additionally, loss rates varied across different enrollment locations, with higher enrollment numbers generally associated with higher loss rates. [Conclusion] Through a comprehensive analysis of donor loss, our center has adjusted its strategies for establishing the donor pool. These findings also provide valuable insights for other blood collection and supply institutions in building platelet donor banks.

Polycystic ovary syndrome(PCOS) and its resulting infertility is one of the common diseases of gynecology and reproductive endocrinology. The phosphatidylinositol 3-kinase/protein kinase B(PI3K/Akt) signaling pathway is relatively well-studied in the development of intervention in PCOS, and the experiments on PCOS in rats conducted by traditional Chinese medicine through this signaling pathway is also the main direction of mechanistic research. In this paper, 20 articles published in academic journals in the past 5 years were selected through the corresponding criteria, and the objective situation and existing problems of the selected research projects were analyzed from five aspects, namely, baseline data, modeling and treatment, grouping, evaluative indexes, and pharmacodynamic indexes. It is found that there were different degrees of problems in each research project, such as the observation indicators of modeling, criteria for judging the success of the model, the treatment period, the calculation of dosage of prescription/active ingredients and specific dosage were not clearly defined, which could easily lead the bias of the results or reduce the validity of experimental data. Based on this, the list of PCOS rat experimental research operations was formed, involving five categories of experimental rats, model construction, study implementation, outcome measures and analysis and report with a total of 21 operation lists, with a view to provide a reference for the subsequent PCOS experiments related to scientific research and helping to form high-quality results.
7.Advances in early diabetic neuroretinopathy
International Eye Science 2025;25(1):76-81
Diabetic retinopathy(DR)is a late-stage peripheral micro-neurovascular complication of chronic hyperglycemia, leading to blood-retinal barrier impairment and retinal dysfunction. Recent studies have found that diabetic neuroretinopathy(DN)may be one of the earliest events in diabetic retinal alterations. The main features include defective electroretinographic responses in newly diagnosed patients, early self-activation of microglia and Müller cells, reduced activity of neurotransmitters(e.g., DOPA/GABA), and early mitochondrial dysfunction, such as persistent Drp1-Fis1 fission and mtDNA methylation mismatches. Understanding the molecular basis of DN is essential for elucidating its pathogenesis and developing early treatments. This review summarizes pathological changes and mechanisms of retinal function, glial cells, neurotransmitters, mitochondria, and other factors in early diabetes mellitus, in order to provide a theoretical foundation for investigating early DN mechanisms and developing targeted therapies.

ObjectiveBy comparing the composition and content of volatile components in raw products, wine-washed products and wine-fried products of Ligusticum sinense cv. Chaxiong rhizome(LSCR), to investigate the influence of wine processing on the volatile components of LSCR, in order to provide a basis for the development of quality standards for LSCR and its processed products. MethodsElectronic nose was used to identify the odors of LSCR, wine-washed and wine-fried LSCR, and their volatile components were detected by headspace gas chromatography-mass spectrometry(HS-GC-MS), and the relative mass fractions of these components were determined by peak area normalization method. Principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) were performed on the obtained sample data by SIMCA 14.1 software, and the differential components of LSCR, wine-washed and wine-fried LSCR were screened according to the variable importance in the projection(VIP) value>1. Pearson correlation analysis was used to explore the relationship between volatile differential flavor components and electronic nose sensors. ResultsElectronic nose detection results showed that there were significant differences in the odors of LSCR, wine-washed and wine-fried LSCR, mainly reflected in the sensors S2, S4, S5, S6, S11, S12, S13. And a total of 62 compounds were identified from LSCR and its wine-processed products, among which 46, 50 and 51 compounds were identified from LSCR, wine-fried and wine-washed LSCR, respectively. There were 21 differential components between the raw products and wine-fried products, of which 10 components were increased and 11 were decreased after processing. There were 20 differential components between the raw products and wine-washed products, of which 11 constituents increased and 9 decreased after processing. There were 17 differential components between the wine-wash products and wine-fried products. Compared with the wine-washed products, the contents of 13 components in the wine-fried products increased, and the contents of 4 components decreased. The increasing trend of the content of phthalides in the wine-washed products was more obvious than that in the wine-fried products, but the content of total volatile components was higher in the wine-fried products than the wine-washed products. Correlation analysis showed that there were different degrees of correlation between the 7 differential sensors of electronic nose and 24 differential volatile components, mainly phthalides and olefins. ConclusionThe odor and the content of volatile components in LSCR changed obviously after wine processing, and n-butylphthalide, Z-butylidenephthalide and E-ligustilide can be used as the candidate differential markers of volatile components in LSCR before and after wine processing.

Viral pneumonia is an infectious disease caused by virus invading the lung parenchyma and interstitial tissue and causing lung inflammation, with the incidence rising year by year. Traditional Chinese medicine (TCM) can treat viral pneumonia in a multi-component, multi-target, and holistic manner by targeting the core pathogenesis of pneumonia caused by different respiratory viruses, demonstrating minimal side effects and significant advantages. According to the theory of healthy Qi and pathogenic Qi in TCM, the struggle between healthy Qi and pathogenic Qi and the imbalance between immunity and inflammation run through the entire process of viral pneumonia, and the immunity-inflammation status at different stages of the disease reflects different relationships between healthy Qi and pathogenic Qi. Immune dysfunction leads to the deficiency of healthy Qi, causing viral infections. The struggle between healthy Qi and pathogenic Qi causes immunity-inflammation imbalance, leading to the onset of viral pneumonia. Inflammatory damage causes persistent accumulation of phlegm and stasis, leading to the progression of viral pneumonia. The cytokine storm causes immunodepletion, leading to the excess of pathogenic Qi and diminution of healthy Qi and the deterioration of viral pneumonia. After the recovery from viral pneumonia, there is a long-term imbalance between immunity and micro-inflammation, which results in healthy Qi deficiency and pathogenic Qi lingering. Healthy Qi deficiency and pathogenic Qi excess act as common core causes of pneumonia caused by different respiratory viruses. Clinical treatment should emphasize both replenishing healthy Qi and eliminating pathogenic Qi, helping to restore the balance between healthy Qi and pathogenic Qi as well as between immunity and inflammation, thus promoting the recovery of patients from viral pneumonia. According to the TCM theory of healthy Qi and pathogenic Qi, this article summarizes the immunity-inflammation mechanisms at different stages of viral pneumonia, and explores the application of the method of replenishing healthy Qi and eliminating pathogenic Qi in viral pneumonia. The aim is to probe into the scientific connotation of the TCM theory of healthy Qi and pathogenic Qi in viral pneumonia and provide ideas for the clinical application of the method of replenishing healthy Qi and eliminating pathogenic Qi to assist in the treatment of viral pneumonia.

Sepsis is a systemic inflammatory response syndrome caused by the invasion of pathogenic microorganisms such as bacteria. In addition to the manifestations of systemic inflammatory response syndrome and primary infection lesions, critical cases often have manifestations of organ hypoperfusion. The morbidity and mortality of sepsis have remained high in recent years, which seriously affect the quality of life of the patients. The pathogenesis of sepsis is complicated, in which uncontrollable inflammation is a key mechanism. The phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signaling pathway plays a key role in mediating inflammation in sepsis. The available therapies of sepsis mainly include resuscitation, anti-infection, vasoactive drugs, intensive insulin therapy, and organ support, which show limited effects of reducing the mortality. Therefore, finding new therapeutic drugs is a key problem to be solved in the clinical treatment of sepsis. In recent years, studies have shown that traditional Chinese medicine (TCM) can regulate the PI3K/Akt pathway via multiple pathways, multiple effects, and multiple targets to inhibit inflammation and curb the occurrence and development of sepsis, which has gradually become a hot spot in the prevention and treatment of sepsis. Moreover, studies have suggested that TCM has unique advantages in the treatment of sepsis. TCM can regulate the PI3K/Akt signaling pathway to inhibit inflammation, reduce oxidative stress, and control apoptosis in the prevention and treatment of sepsis. Despite the research progress, a systematic review remains to be performed regarding the TCM treatment of sepsis by regulating the PI3K/Akt signaling pathway. After reviewing relevant papers published in recent years, this study systematically summarizes the relationship between PI3K/Akt pathway and sepsis and the role of TCM in the treatment of sepsis, aiming to provide new ideas for the potential treatment of sepsis and the development of new drugs.
