Pharmacological management of polycystic ovary syndrome.

Polycystic ovary syndrome is a common and frequently undiagnosed female endocrine disorder that is associated with diverse symptoms and features, and an increased risk of long-term chronic diseases such as type 2 diabetes and cardiovascular disease. Pharmacotherapy for polycystic ovary syndrome should be directed at the key concerns of the individual patient. The combined oral contraceptive pill or metformin may be prescribed for irregular periods. The combined oral contraceptive pill is preferred over antiandrogens for treatment of hirsutism and acne. Metformin is of benefit for reducing excess body weight and improving hormonal and metabolic outcomes in those with high metabolic risk (e.g. body mass index greater than 25 kg/m2). Inositol appears to have limited benefits for metabolic outcomes, although it is associated with fewer adverse effects than metformin. Modification of lifestyle factors is important as part of a holistic approach to managing polycystic ovary syndrome. Anti-obesity drugs may be considered for weight management in addition to lifestyle interventions.

A UPLC-MS/MS coupled with GC-MS method for quantification of twenty-one chemical ingredients from Suxiao Jiuxin pill in multiple tissue of rat and its application to tissue distribution study.

Suxiao Jiuxin pill (SJP) was a commonly-used traditional Chinese medicine for treating cardiovascular diseases. It was composed of the rhizome of Ligusticum chuanxiong Hort. and Borneolum Syntheticum. The distribution of SJP in vivo was still ambiguous. A UPLC-MS/MS coupled with GC-MS method was developed to quantify twenty-one chemical ingredients in multiple tissues from rat after administration of SJP. Protein precipitation and liquid-liquid microextraction were both utilized in sample pretreatment. All analytes were detected under acceptable specificity, linearity (correlation coefficient > 0.992), sensitivity (LLOQ < 12.5 ng/mL), precision (RSD < 14.8 %), accuracy (RE < ±14.6 %), extraction recovery (between 52.8 % and 124.1 %), matrix effect (ranged from 60.5 % and 149.7 %) and stability (RE < ±16.0 %). The established method was successfully applied in the tissue distribution study of SJP in rats. As a result, the distribution characteristics of ten analytes were clearly elucidated, including borneol, isoborneol, ligustilide, senkyunolide A, ferulic acid, senkyunolide I, levistolide A, neocnidilide, senkyunolide H and angelicide. The information provided by this research was greatly meaningful for the active chemical ingredient exploration and clinical application of SJP.

Exploring the potential mechanism of Xiaojin Pill therapy for benign prostatic hyperplasia through metabolomics and gut microbiota analysis.

Background: Xiaojin Pill (XJP) is a traditional Chinese medicine prescribed for treating benign prostatic hyperplasia (BPH). It has been proven to have multiple effects, such as regulating sex hormone levels, exhibiting anti-tumor, anti-inflammatory, analgesic, and anti-platelet aggregation properties, and improving immunity. However, the material basis of XJP's therapeutic effect on BPH and its metabolic process in vivo remains to be clarified. At the same time, many microorganisms that exist in the urogenital tract, including those related to BPH, can also affect the health of the host. Methods: Using ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS), the chemical components of XJP were identified. A BPH model was created through bilateral testicular ablation and injections of testosterone propionate. A comprehensive evaluation of XJP efficacy was conducted using pathological ELISA, TUNEL, and immunohistochemical techniques. In addition, UPLC-MS metabolomics and 16S rRNA sequencing revealed the serum metabolic profile and intestinal microbiota composition. We performed a Spearman correlation coefficient analysis to highlight the interactions between "intestinal microbiota-serum factors" and "intestinal microbiota-metabolites." Results: XJP contains 91 compounds that alleviate pathologies of BPH in rats, decreasing prostate weight, index, and serum levels of Dihydrotestosterone (DHT), Prostate-Specific Antigen (PSA), epidermal growth factor (EGF), basic fibroblast growth factor (bFGF), and vascular endothelial growth factor (VEGF) levels. It inhibits prostatic epithelial cell apoptosis and downregulates Bax, TGF-ß1, and IGF-1 proteins in the caspase-3 pathway. Metabolomics studies have revealed 10 upregulated and 10 downregulated metabolites in treated rats, with 5-methylcytosine, uracil, and cytosine enriched in pyrimidine metabolism. L-arginine plays a pivotal role in metabolic pathways encompassing pyrimidine metabolism, arginine biosynthesis, and the mammalian target of rapamycin (mTOR) signaling pathway. 16S rRNA sequencing revealed that XJP optimized the diversity and balance of intestinal flora in BPH rats by decreasing the Bacteroidetes/Firmicutes (B/F) ratio, enhancing the beneficial bacteria, such as Eggerthellaceae, Anaerovoracaceae, and Romboutsia, and suppressing the dysfunctional bacteria, such as Atopobiaceae, Prevotellaceae_NK3B31_group, Dorea, and Frisingicoccus. According to the Spearman correlation coefficient analysis, Lactobacillus was found to be most associated with serum factors, whereas Romboutsia showed the highest correlation with metabolites. This finding suggests that XJP modulates pyrimidine metabolism disorders in BPH rats, a regulation that aligns closely with Romboutsia, Prevotellaceae_NK3B31_group, Lactobacillus, Chujaibacter, and Enterorhabdus, thereby providing valuable biological insights. Conclusion: In summary, these findings indicate that XJP possesses a synergistic anti-BHP effect through its multi-component, multi-target, multi-gut microbiota, and multi-metabolic pathway properties. The effect involves the regulation of sex hormone levels, growth factors, and the anti-epithelial cell apoptosis process. The modulation of specific gut microbiota by the host and the involvement of multiple metabolic pathways are likely one of the significant mechanisms of XJP in treating BPH. Notably, pyrimidine metabolism and the intestinal microbial ecosystem are closely intertwined in this process.

Identification of kidney-related medications using AI from self-captured pill images.

INTRODUCTION: ChatGPT, a state-of-the-art large language model, has shown potential in analyzing images and providing accurate information. This study aimed to explore ChatGPT-4 as a tool for identifying commonly prescribed nephrology medications across different versions and testing dates. METHODS: 25 nephrology medications were obtained from an institutional pharmacy. High-quality images of each medication were captured using an iPhone 13 Pro Max and uploaded to ChatGPT-4 with the query, 'What is this medication?' The accuracy of ChatGPT-4's responses was assessed for medication name, dosage, and imprint. The process was repeated after 2 weeks to evaluate consistency across different versions, including GPT-4, GPT-4 Legacy, and GPT-4.Ø. RESULTS: ChatGPT-4 correctly identified 22 out of 25 (88%) medications across all versions. However, it misidentified Hydrochlorothiazide, Nifedipine, and Spironolactone due to misreading imprints. For instance, Nifedipine ER 90 mg was mistaken for Metformin Hydrochloride ER 500 mg because 'NF 06' was misread as 'NF 05'. Hydrochlorothiazide 50 mg was confused with the 25 mg version due to imprint errors, and Spironolactone 25 mg was misidentified as Naproxen Sodium or Diclofenac Sodium. Despite these errors, ChatGPT-4 showed 100% consistency when retested, correcting misidentifications after receiving feedback on the correct imprints. CONCLUSION: ChatGPT-4 shows strong potential in identifying nephrology medications from self-captured images, though challenges with difficult-to-read imprints remain. Providing feedback improved accuracy, suggesting ChatGPT-4 could be a valuable tool in digital health for medication identification. Future research should enhance the model's ability to distinguish similar imprints and explore broader integration into digital health platforms.

Prevalence of self-reported voice and swallowing complaints in an outpatient geriatric population.

Background: Older adults suffer from increased rates of dysphagia and dysphonia, both of which have a profound effect on quality of life and are often underdiagnosed. We sought to better understand the prevalence of these complaints and the potential utility of a patient-reported screening program in a geriatrics clinic. Methods: Using an IRB-approved cross-sectional survey and retrospective cohort design, we recruited participants from a population of new patients seeking care at an academic geriatrics clinic. We used three validated questionnaires to assess self-reported dysphagia, dysphonia, and pill dysphagia: the Eating-Assessment Tool-10 (EAT-10), the Voice Handicap Index-10 (VHI-10), and the PILL-5. Patients who screened positive on any questionnaire were offered referral to a laryngologist for additional evaluation. Patients who screened positive on the PILL-5 were also offered referral to our geriatric pharmacist. Results: Among our 300 patients surveyed, the mean age was 76 (SD 8.46). A total of 82 (27.3%) patients screened positive (73 on EAT-10, 10 on PILL-5, 13 on VHI-10) and were offered referral, of which 36 accepted. These positive screening patients took more prescription medications (p = .024) and had a higher GDS score (p < .001) when compared to the patients who screened negative. Conclusions: Many new patients seeking generalized care at our center screened positively for dysphagia and/or dysphonia on validated questionnaires. Geriatric patients may benefit from integrating screening for these disorders to identify the need of further evaluation. It is unknown if these survey tools are appropriate in a non-otolaryngology clinic. Level of evidence: III.

Zuogui Pills Improve the Learning and Memory Ability of Brain-Aging Mice through the Estrogen Receptor ERα Methylation Pathway.

INTRODUCTION: Sex hormones are important factors in maintaining brain function and acting as brain protectors. Recent research suggests that neuronal damage in brain aging may be linked to the methylation of the estrogen receptor α (ERα). However, the mechanism of Zuogui Pills (ZGW) in brain-aging ERα DNA methylation and neuronal repair remains unknown. MATERIALS AND METHODS: D-galactose-induced ovary removal mice were used as a model of aging. Changes in estrous cycle were detected in mice by vaginal cell smear. Animal behavior tests, including the Morris water maze (MWM) and new object recognition (NOR) test, were conducted. Hematoxylin-eosin (HE) and Nissl-staining were carried out to assess hippocampal neurogenesis. Enzyme-linked immunosorbent assay (ELISA) was performed for 5- methylcytosine methylation levels, and immunohistochemistry (IHC) and western blotting (WB) experiments were performed to assess ERα/DNA methyltransferase 1 (DNMT1) expression after ZGW treatment. Finally, bisulfite sequencing PCR (BSP) analysis was performed to identify methylated differentially expressed estrogen receptor 1 (ESR1) gene in D-gal-induced senescent neurons before and after ZGW treatment. RESULTS: We found that ERα methylation was involved in the delayed brain ageing process of ZGW. Mechanistically, ZGW can improve the learning and memory ability of brain-aging mice, reduce the expression of 5-methylcytosine (5-mc) in serum, increase the amount of ERα, inhibit the expression of DNMT1, and significantly reduce methylated expression of the ESRI gene. CONCLUSION: Our data suggested that ZGW slowed down D-gal-induced brain aging in mice, and these results showed that ZGW is beneficial for aging. It may be used for neuronal protection in aging.

Characterization and In vitro Release & In vivo Behavior Study of Self-Assembled Nano-Emulsion in XiaoYao Pill for Enhanced Drug Delivery.

BACKGROUND: Traditional Chinese medicine formulations often contain hydrophobic components with limited solubility and stability, leading to low oral bioavailability. Self-assembled nanoparticles (SANs) have shown promise in enhancing oral bioavailability of these components. However, whether un-decocted Chinese herbal pellets can generate SANs and the impact of SANs formed by multiple components on pharmacokinetic parameters remains unexplored. METHODS: In this study, single-factor approach was employed to determine the optimal separation method of nano-emulsion phase of XiaoYao pill (N-XY). Morphological and particle size analyses confirmed the nanoscale nature of N-XY. High-performance liquid chromatography (HPLC) fingerprint analysis was conducted to compare the distribution of active ingredients among three different phases of XiaoYao pill (XY pill). In vitro release studies were performed to evaluate the release mechanism of four ingredients from N-XY. Additionally, in vivo pharmacokinetics and tissue distribution behaviors were investigated in rats. RESULTS: N-XY exhibited uniform and stable characteristics as a water-in-oil (O/W) nano-emulsion. Fingerprint analysis identified 25 characteristic peaks and 8 key ingredients in N-XY, with the highest peak areas. In vitro release studies showed a sustained release behavior of N-XY. The pharmacokinetics study showed that the ferulic acid of N-XY had a 1.37-fold higher AUC, 1.44-fold lower Vd/F, 1.39-fold lower CL/F, and a prolonged t1/2 than A-XY, indicating enhanced bioavailability due to reduced elimination. Furthermore, the tissue distribution revealed that the levels of paeoniflorin and ferulic acid from N-XY significantly increased in liver, spleen, lungs, uterus and ovaries, exhibiting targeting characteristics. CONCLUSION: This study comprehensively explored the formation, characterization, and pharmacokinetics of nano-emulsion in XY pill, introducing novel perspectives and initiating preliminary research on potential SANs in un-decocted traditional Chinese medicine formulations. It also emphasized the importance of enhancing pharmacokinetics of hydrophobic components in Chinese herbal formulations and laid the foundation for future nano-formulation research for XY pill.

Dahuang Zhechong Pill Improves Pulmonary Fibrosis through miR-29b-2-5p/HK2 Mediated Glycolysis Pathway.

OBJECTIVE: To explore the preventive and therapeutic effects of Dahuang Zhechong Pill (DZP) on pulmonary fibrosis and the underlying mechanisms. METHODS: The first key rate-limiting enzyme hexokinase 2 (HK2) of glycolysis was silenced and over-expressed through small interfering RNA and lentivirus using lung fibroblast MRC-5 cell line, respectively. The cell viability, migration, invasion and proliferation were detected by cell counting kit-8, wound healing assay, transwell assay, and flow cytometry. The mRNA and protein expression levels of HK2 were detected by RT-PCR and Western blotting, respectively. The contents of glucose, adenosine triphosphate (ATP) and lactate in MRC-5 cells were determined by enzyme-linked immunosorbnent assay (ELISA). Then, the relationship between miR-29b-2-5p and HK2 was explored by luciferase reporter gene assay. Pulmonary fibrosis cell model was induced by transforming growth factor-ß 1 (TGF-ß 1) in MRC-5 cells, and the medicated serum of DZP (DMS) was prepared in rats. MRC-5 cells were divided into control, TGF-ß 1, TGF-ß 1+10% DMS, TGF-ß 1+10% DMS+miR-29b-2-5p inhibitor, TGF-ß 1+10% DMS+inhibitor negative control, TGF-ß 1+10% DMS+miR-29b-2-5p mimic and TGF-ß 1+10% DMS+mimic negative control groups. After miR-29b-2-5p mimics and inhibitors were transfected into MRC-5 cells, all groups except control and model group were treated with DMS. The effect of DMS on MRC-5 cells were detected using aforementioned methods and immunofluorescence. Similarly, the contents of glucose, ATP and lactate in each group were measured by ELISA. RESULTS: The mRNA and protein expressions of HK2 in MRC-5 cells were successfully silenced and overexpressed through si-HK2-3 and lentiviral transfection, respectively. After silencing HK2, the mRNA and protein expressions of HK2 were significantly decreased (P<0.01), and the concentrations of glucose, ATP and lactate were also significantly decreased (P<0.05). The proliferation, migration and invasion of MRC-5 cells were significantly declined (P<0.05 or P<0.01), while the apoptosis of MRC-5 cells was significantly increased (P<0.01). After overexpressing HK2, the mRNA and protein expressions of HK2 were significantly increased (P<0.05), and the concentrations of glucose, ATP and lactate were also significantly increased (P<0.05 or P<0.01). The proliferation, migration and invasion of MRC-5 cells were significantly increased (P<0.05 or P<0.01), while the apoptosis of MRC-5 cells was significantly decreased (P<0.05). The relative luciferase activity of 3'UTR-WT+hsa-miR-29b-2-5p transfected with HK2 was significantly decreased (P<0.01). After miR-29b-2-5p mimic and inhibitor were transfected into the MRC-5 cells, DMS intervention could significantly reduce the concentration of glucose, ATP and lactate, and the mRNA and proteins expressions of HK2, phosphofructokinase and pyruvate kinase isoform M2 (P<0.05 or P<0.01). The proliferation, migration and invasion of MRC-5 cells were alleviated (P<0.05 or P<0.01), and the deposition of fibronectin, α-smooth muscle actin, and collagen I were significantly decreased (P<0.05 or P<0.01). CONCLUSIONS: Glycolysis is closely related to pulmonary fibrosis. DZP reduced glycolysis and inhibited fibroblasts' excessive differentiation and abnormal collagen deposition through the miR-29b-2-5p/HK2 pathway, which played a role in delaying the process of pulmonary fibrosis.

Preference for a Novel Oral Alternative to Parenterally Administered Medications.

Background: Rani Therapeutics is developing a robotic pill (RP), an oral drug delivery platform called RaniPill™ that can deliver a number of biotherapeutics with high bioavailability; eliminating the need for injections. While patients in general prefer oral to injectable therapies, preference for a more frequent oral regimen compared to a less frequent injectable regimen is unknown. Two marketing surveys were conducted to gather data on preference for oral versus injectable therapies. A clinical study gathered data on participant preference for oral pills vs injections before and after swallowing a Mock-RP capsule. Methods: A total of 1689 adults taking injections (mean duration 3-7 years) to treat endocrine or inflammatory conditions were anonymously surveyed online for their preference to administer/prescribe medications orally via the RP. In the clinical study, 150 participants currently taking injections for chronic conditions evaluated the swallowability of a Mock-RP and completed a questionnaire regarding their preferences. Results: Majority of respondents surveyed stated they would be willing to convert to an oral alternative over their current parenteral therapy regardless of drug or disease. In the clinical study, all participants were able to swallow the Mock-RP and 91% indicated their preference for the oral route versus their current parenteral route of drug administration. Survey respondents and those in the clinical study using frequent injections were more willing to select a once-daily capsule compared to those injecting infrequently. Even study participants who inject infrequently (≥monthly: 80%) would prefer a once-daily pill over their injection regimen. Conclusion: Patients taking injections and prescribing physicians strongly prefer oral dosing to parenteral administration of biologics even if dosing frequency with the oral option, such as the RP, is increased.

Impact of preoperative age-adjusted sagittal imbalance on radiographic and clinical outcomes following 1-level minimally invasive transforaminal lumbar interbody fusion for degenerative spondylolisthesis.

OBJECTIVE: Prior studies investigating the use of minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) for treatment of degenerative lumbar conditions and concomitant sagittal deformity have not stratified patients by preoperative pelvic incidence (PI)-lumbar lordosis (LL) mismatch, which is the earliest parameter to deteriorate in mild sagittal deformity. Thus, the aim of the present study was to determine the impact of preoperative PI-LL mismatch on clinical outcomes and sagittal balance restoration among patients undergoing MI-TLIF for degenerative spondylolisthesis (DS). METHODS: Consecutive adult patients undergoing primary 1-level MI-TLIF between April 2017 and April 2022 for DS with ≥ 6 months radiographic follow-up were included. Patient-reported outcome measures (PROMs) included the Oswestry Disability Index, visual analog scale (VAS), 12-Item Short-Form Health Survey (SF-12), and Patient-Reported Outcomes Measurement Information System at preoperative, early postoperative (< 6 months), and late postoperative (≥ 6 months) time points. The minimal clinically important difference (MCID) for PROMs was also evaluated. Radiographic parameters included PI, LL, pelvic tilt (PT), and sagittal vertical axis (SVA). Patients were categorized into balanced and unbalanced groups based on preoperative PI-LL mismatch according to age-adjusted alignment goals. Changes in radiographic parameters and PROMs were evaluated. RESULTS: Eighty patients were included (L4-5 82.5%, grade I spondylolisthesis 82.5%, unbalanced 58.8%). Mean clinical and radiographic follow-up were 17.0 and 8.3 months, respectively. The average preoperative PI-LL was 18.8° in the unbalanced group and -3.3° in the balanced group. Patients with preoperative PI-LL mismatch had significantly worse preoperative PT (26.2° vs 16.4°, p < 0.001) and SVA (53.2 vs 9.0 mm, p = 0.001) compared with balanced patients. Patients with preoperative PI-LL mismatch also showed significantly worse PI-LL (16.0° vs 0.54°, p < 0.001), PT (25.9° vs 18.7°, p < 0.001), and SVA (49.4 vs 22.8 mm, p = 0.013) at long-term follow-up. No significant radiographic improvement was observed among unbalanced patients. All patients demonstrated significant improvements in all PROMs (p < 0.05) except for SF-12 mental component score. Achievement of MCID for VAS back score was significantly greater among patients with preoperative PI-LL mismatch (85.7% vs 65.5%, p = 0.045). CONCLUSIONS: Although 1-level MI-TLIF did not restore sagittal alignment in patients with preoperative PI-LL mismatch, patients presenting with DS can expect significant improvement in PROMs following 1-level MI-TLIF regardless of preoperative alignment or extent of correction. Thus, attaining good clinical outcomes in patients with mild sagittal imbalance may not require addressing imbalance directly.

Effects of Bifidobacterium bifidum tetragonum tablets and Jin Gui Ren Qi Pill on intestinal flora and metabolism in patients with diabetic kidney disease.

Objective: To investigate the effects of Bifidobacterium bifidum tetragonum tablets and Jin Gui Ren Qi Pill on intestinal flora and metabolism in patients with diabetic kidney disease. Methods: In the study conducted at Heping Hospital of Changzhi Medical College from March 2021 to December 2022, 30 cases of patients diagnosed with diabetic nephropathy were meticulously selected as study subjects. Employing a double-blind randomized table method, these patients were randomly allocated into three groups: the control group (n = 10), the Bifidobacterium bifidum tetragonum tablets group (n = 10), and the Jin Gui Ren Qi Pill group (n = 10). The control group received standard western medical treatments for diabetic nephropathy, including serum glucose, blood lipids, blood pressure management, and other conventional therapies. In addition to the standard treatments, the Bifidobacterium bifidum tetragonum tablets group received Bifidobacterium bifidum tetragonum tablets, while the Jin Gui Ren Qi Pill group received Jin Gui Ren Qi Pill. Before and after a 4-week treatment period, various baseline parameters were assessed, including fasting blood glucose, 2-h postprandial blood glucose, triglycerides, serum total cholesterol, serum low-density lipoprotein cholesterol, serum high-density lipoprotein cholesterol, random urine microalbumin/creatinine ratio (ACR), blood creatinine (SCr), and traditional Chinese medicine evidence scores. Stool specimens were collected from all three groups before and after treatment for 16S rDNA high-throughput sequencing, followed by comprehensive analyses including OUT clustering, Alpha diversity, Beta diversity, species composition analysis, LEfSe analysis, and KEGG function prediction. Spearman correlation analysis was employed to explore the relationship between intestinal flora and clinical indicators. Furthermore, fasting peripheral venous blood was collected from patients in the Bifidobacterium tetrapunctate tablets group and the control group before and after intervention to measure the optical density values of tumor necrosis factor-α (TNF-α), interleukin-2 (IL-2), and interleukin-6 (IL-6) using the Beijing Biolite ELISA kit. This study was conducted with the approval of the Ethics Committee of Changzhi Medical College. Results: 1. The 2hPBG, total cholesterol and LDL levels were observed among patients with diabetic kidney disease (DKD) across all groups: the Jin Gui Ren Qi Pill group, the Bifidobacterium bifidum tetragonum tablets group, and the control group (p < 0.05). 2. The Jin Gui Ren Qi Pill demonstrated superior efficacy in alleviating TCM symptoms and reducing the ACR compared to both the Bifidobacterium bifidum tetragonum tablets group and the control group. Conversely, Bifidobacterium bifidum tetragonum tablets exhibited a more pronounced reduction in TC levels compared to both the Jin Gui Ren Qi Pill and control groups. Notably, Bifidobacterium bifidum tetragonum tablets effectively decreased (IL-2) levels in patients with DKD. 3. Bifidobacterium bifidum tetragonum tablets also demonstrated efficacy in reducing IL-2 levels in DKD patients. 4. Analysis of intestinal microorganism abundance and diversity before and after the intervention, as well as among the three groups, revealed no significant alterations. Similarly, comparisons of ACE, Chao, Simpson, and Shannon indices showed no statistically significant differences (p > 0.05). 5. Qualitative analysis of intestinal microorganisms before and after intervention, as well as among the three groups, indicated no significant differences. Anosim test results also did not reveal qualitative distinctions (Anosim test R = 0.021, p = 0.215). 6. LEfSe analysis unveiled a noteworthy increase in Prevotella_7 abundance within the Jin Gui Ren Qi Pill group post-intervention (p < 0.05). 7. Furthermore, Chinese medicine evidence scores, body mass index, TC, and LDL levels correlated positively with the relative abundance of Tyzzerella_3 bacterial flora. Conversely, age, disease duration, and 2hPBG correlated positively with the relative abundance of Christensenellaceae_R_7 flora, while TC and LDL levels displayed a negative correlation with the relative abundance of Christensenellaceae_R_7 flora. Conclusion: The combination of Jin Gui Ren Qi Pill with western medical treatment exhibited superior efficacy in ameliorating clinical symptoms and reducing the ACR in patients with DKD compared to western medical treatment alone. Furthermore, this combination therapy led to an increase in the abundance of Prevotella_7 within the intestinal flora of patients, suggesting a potential enhancement in carbohydrate metabolism by the intestinal microbiota. On the other hand, Bifidobacterium bifidum tetragonum tablets bacterial tablets combined with western medical treatment demonstrated enhanced efficacy in reducing TC levels in DKD patients compared to western medical treatment alone. Additionally, this combination therapy effectively reduced the levels of IL-2 in DKD patients, thus mitigating inflammation in these individuals.

Exploring the anti-hepatocellular carcinoma effects of Xianglian Pill: Integrating network pharmacology and RNA sequencing via in silico and in vitro studies.

BACKGROUND: Liver cancer represents a most common and fatal cancer worldwide. Xianglian Pill (XLP) is an herbal formula holding great promise in clearing heat for treating diseases in an integrative and holistic way. However, due to the complex constituents and multiple targets, the exact molecular mechanisms of action of XLP are still unclear. PURPOSE: This study is focused on hepatocellular carcinoma (HCC), the most common type of liver cancer. The aim of this study is to develop a fast and efficient model to investigate the anti-HCC effects of XLP, and its underlying mechanisms. MATERIALS AND METHODS: HepG2, Hep3B, Mahlavu, HuH-7, or Li-7 cells were employed in the studies. The ingredients were analyzed using liquid chromatography tandem mass spectrometry (LC-MS). RNA sequencing combined with network pharmacology was used to elucidate the therapeutic mechanism of XLP in HCC via in silico and in vitro studies. An approach was constructed to improve the accuracy of prediction in network pharmacology by combining big data and omics. RESULTS: First, we identified 13 potential ingredients in the serum of XLP-administered rats using LC-MS. Then the network pharmacology was performed to predict that XLP demonstrates anti-HCC effects via targeting 94 genes involving in 13 components. Modifying the database thresholds might impact the accuracy of network pharmacology analysis based on RNA sequencing data. For instance, when the matching rate peak is 0.43, the correctness rate peak is 0.85. Moreover, 9 components of XLP and 6 relevant genes have been verified with CCK-8 and RT-qPCR assay, respectively. CONCLUSION: Based on the crossing studies of RNA sequencing and network pharmacology, XLP was found to improve HCC through multiple targets and pathways. Additionally, the study provides a way to optimize network pharmacology analysis in herbal medicine research.

Effectiveness and Safety of Qishen Yiqi Dripping Pill in Patients with Acute Coronary Syndrome after Percutaneous Coronary Intervention: 3-Year Results from a Multicentre Cohort Study.

OBJECTIVES: To evaluate the effectiveness and safety of Qishen Yiqi Dripping Pill (QSYQ) in patients with acute coronary syndrome (ACS) after percutaneous coronary intervention (PCI). METHODS: This multicentre prospective cohort study was conducted at 40 centers in China. Patients with ACS after PCI entered either the QSYQ or Western medicine (WM) groups naturally based on whether they had received QSYQ before enrollment. QSYQ group received QSYQ (0.52 g, 3 times a day for 12 months) in addition to WM. The primary endpoint included cardiac death, non-fatal myocardial infarction, and urgent revascularization. The secondary endpoint included rehospitalization due to ACS, heart failure, stroke, and other thrombotic events. Quality of life was assessed by the Seattle Angina Questionnaire (SAQ). RESULTS: A total of 936 patients completed follow-up of the primary endpoint from February 2012 to December 2018. Overall, 487 patients received QSYQ and WM. During a median follow-up of 566 days (inter quartile range, IQR, 517-602), the primary endpoint occurred in 46 (9.45%) and 65 (14.48%) patients in QSYQ and WM groups respectively [adjusted hazard ratio (HR) 0.60, 95% confidence interval (CI) 0.41-0.90; P=0.013]. The secondary endpoint occurred in 61 (12.53%) and 74 (16.48%) patients in QSYQ and WM groups, respectively (adjusted HR 0.76, 95% CI 0.53-1.09; P=0.136). In sensitivity analysis, the results still demonstrated that WM combined with QSYQ reduced the risk of the primary endpoint (HR 0.67, 95% CI 0.46-0.98; P=0.039). Moreover, QSYQ improved the disease perception domain of the SAQ (P<0.05). CONCLUSION: In patients with ACS after PCI, QSYQ combined with WM reduced the incidence of the primary endpoint. These findings provide a promising option for managing ACS after PCI and suggest the potential treatment for reducing the risk of primary endpoint included cardiac death, non-fatal myocardial infarction, and urgent revascularization through intermittent administration of QSYQ (Registration No. ChiCTR-OOC-14005552).

Shexiang Tongxin dropping pill ameliorates microvascular obstruction via downregulating ALOX12 after myocardial ischemia-reperfusion.

BACKGROUND: Microvascular dysfunction (MVD) is common in patients with myocardial infarction receiving reperfusion therapy and is associated with adverse cardiac prognosis. Accumulating evidence suggests a protective role of Shexiang Tongxin dropping pill (STDP) in MVD. However, the specific effects and the underlying mechanisms of STDP in the context of MVD after myocardial ischemia-reperfusion (IR) remains unclear. AIMS: We aimed to elucidate the role of STDP in MVD induced by IR and the potential mechanisms involved. METHODS: Mice were orally administered with STDP or normal saline for 5 days before receiving myocardial IR. Cardiac function and microvascular obstruction was measured. Proteomics and single-cell RNA sequencing was performed on mouse hearts. In vitro hyoxia/reoxygenation model was established on mouse cardiac microvascular endothelial cells (MCMECs). RESULTS: STDP improved cardiac function and decreased microvascular obstruction (MVO) in mice after myocardial IR. Proteomics identified ALOX12 as an important target of STDP. Single-cell RNA sequencing further revealed that downregulation of ALOX12 by STDP mainly occurred in endothelial cells. The involvement of ALOX12 in the effect of STDP on MVO was validated by manipulating ALOX12 via endothelial-specific adeno-associated virus transfection in vivo and in vitro. In vivo, overexpression of ALOX12 increased whereas knockdown of ALOX12 decreased MVO and thrombus formation. STDP treatment alleviated the detrimental effects of overexpression of ALOX12. In vitro, overexpression of ALOX12 increased endothelial cell inflammation and platelet adhesion to endothelial cells, which was abolished by STDP treatment. CONCLUSION: Our findings suggest that STDP alleviates MVO after IR, with ALOX12 playing a crucial role.

Mismatch Between Pelvic Incidence and Lumbar Lordosis After Personalized Interbody Fusion: The Importance of Preoperative Planning and Alignment in Degenerative Spine Diseases.

BACKGROUND: Emerging data have highlighted the significance of planning and aligning total and segmental lumbar lordosis with pelvic morphology when performing short-segment fusion with the goal of reducing the risk of adjacent segment disease while also decreasing spine-related disability. This study evaluates the impact of personalized interbody implants in restoring pelvic incidence-lumbar lordosis (PI-LL) mismatch compared with a similar study using stock interbody implants. METHODS: This multicenter retrospective analysis assessed radiographic pre- and postoperative spinopelvic alignment (PI-LL) in patients who underwent 1- or 2-level lumbar fusions with personalized interbody implants for degenerative (nondeformity) indications. The aim was to assess the incidence of malalignment (PI-LL ≥ 10°) both before and after fusion surgery and to determine the rate of alignment preservation and/or correction in this population. RESULTS: There were 135 patients included in this study. Of 83 patients who were aligned preoperatively, alignment was preserved in 76 (91.6%) and worsened in 7 (8.4%). Among the 52 preoperatively malaligned patients, alignment was restored in 23 (44.2%), and 29 (55.8%) were not fully corrected. Among patients who were preoperatively aligned, there was no statistically significant difference in either the "preserved" or "worsened" groups between stock devices and personalized interbody devices. In contrast, among patients who were preoperatively malaligned, there was a statistically significant increase in the "restored" group (P = 0.046) and a statistically significant decrease in the "worsened" groups in patients with personalized interbodies compared with historical stock device data (P < 0.05). CONCLUSIONS: Compared with a historical cohort with stock implants, personalized interbody implants in short-segment fusions have shown a statistically significant improvement in restoring patients to normative PI-LL. Using 3-dimensional preoperative planning combined with personalized implants provides an important tool for planning and achieving improvement in spinopelvic parameters.

Toxicity studies of compound spermatogenic pill:Acute toxicity and subacute toxicity.

ETHNOPHARMACOLOGICAL RELEVANCE: Spermatogenic Pill (SP) is a commonly used clinical preparation in the Third Clinical Hospital of Changchun University of Traditional Chinese Medicine. Has accumulated a good reputation for more than a decade. However, because SP is a hospital clinical agent, it has received little extensive attention from researchers, which has led to a systematic lack of basic research on it. Therefore, it is impossible to determine whether there are safety hazards that may limit its widespread clinical application, and an in-depth toxicological evaluation of SP is essential and urgent. AIM OF THE STUDY: The aim of this study was to assess the safety of SP by conducting acute and subacute toxicity examinations. MATERIALS AND METHODS: Identify active compounds contained in SP by LC-MS, and determination of inorganic elements in SP using ICP-MS. The in vivo acute toxicity of SP was assessed over a duration of 14 days following administration at doses of 7.5, 15, or 30 g/kg. To evaluate subacute toxicity, mice were administered daily doses of SP (7.5, 15, or 30 g/kg) for a period of 28 days. After the treatment period, the animals were euthanized, and standard blood tests, liver and kidney function tests, as well as tests related to glycolipid metabolism, were performed. The principal organs of the mice were collected to calculate organ coefficients and undergo hematoxylin-eosin (HE) staining. RESULTS: LC-MS analysis showed that the active components of SP include Quercetin, Kaempferol, Beta-sitosterol, Stigmasterol, Diosbulbin B, Schizandrin, Naringenin, 2,3-hydroxycinnamic acid, L-proline, Histidine and Pluviatolide. The total amount of detected inorganic elements accounted for 3.0919% of SP. During the SP acute toxicity experiment, the groups that received the drug exhibited no signs of adverse reactions or poisoning symptoms. In subacute toxicity experiments, drug-treated mice showed overall favorable status, but the effects of continuous administration of the 30 g/kg group on body weight and food intake were reduced. An increase in the white marrow of spleen tissue after long-term administration of the drug treatment was also observed, suggesting that the drug can increase the maturation process and the number of mature lymphocytes in the spleen, and improve the lymphocyte immunity and humoral immunity function of the organism. Suggests that possibly this should be taken into account in clinical application. The routine blood examinations, as well as the assessments of liver and kidney functions, and the tests for glucose and lipid metabolism, did not reveal any notable toxic effects. CONCLUSION: SP contains more flavonoids, and terpenoid active ingredients, and is non-toxic in the body. This discovery not only strengthens the safety foundation of its clinical application, provides a solid scientific basis for the establishment of reasonable clinical dosage and the implementation of effective clinical toxicity monitoring, but also further lays a solid theoretical cornerstone for the subsequent clinical drug trials.

Fuzi lizhong pills alter microbial community compositions and metabolite profiles in ulcerative colitis rat with spleen-kidney yang deficiency syndrome.

ETHNOPHARMACOLOGICAL RELEVANCE: Ulcerative colitis (UC) is a chronic inflammatory bowel condition that is frequently related with Spleen-Kidney Yang Deficiency Syndrome (SKYD) in Chinese medicine. Fuzi Lizhong Pill (FLZP), a traditional medicine for SKYD, has been utilized in China for generations, although the exact mechanism by which it treats UC is unknown. AIM OF THE STUDY: The goal of this study is to further understand FLZP's therapeutic mechanism in SKYD-associated UC. MATERIALS AND METHODS: To investigate the impact of FLZP on SKYD-associated UC, we used a comprehensive method that included serum metabolomics and gut microbiota profiling. The chemical composition of FLZP was determined using mass spectrometry. UC rats with SKYD were induced and treated with FLZP. Serum metabolomics and 16S rRNA microbial community analysis were used to evaluate FLZP's effects on endogenous metabolites and gut microbiota, respectively. Correlation analysis investigated the association between metabolites and intestinal flora. A metabolic pathway analysis was undertaken to discover putative FLZP action mechanisms. RESULTS: FLZP contains 109 components, including liquiritin (584.8176 µg/g), benzoylaconine (16.3087 µg/g), benzoylhypaconine (31.9583), and hypaconitine (8.1160 µg/g). FLZP predominantly regulated seven metabolites and eight metabolic pathways involved in amino acid and nucleotide metabolism, with an emphasis on energy metabolism and gastrointestinal digestion. FLZP also influenced intestinal flora variety, increasing probiotic abundance while decreasing pathogenic bacteria prevalence. An integrated investigation identified associations between changes in certain gut flora and energy metabolism, specifically the tricarboxylic acid (TCA) cycle. CONCLUSIONS: FLZP successfully cures UC in SKYD rats by regulating amino acid and energy metabolism. Its positive effects may include altering microbiota composition and metabolite profiles in UC rats with SKYD. These findings shed light on FLZP's mode of action and its implications for UC management.

Investigating the influence of oral contraceptive pill use on multiple sclerosis risk using UK Biobank data.

OBJECTIVE: To investigate the association between oral contraceptive (OC) pill use and the risk of developing multiple sclerosis (MS), attempting to address the limitations present in previous studies that produced conflicting results. DESIGN: A population-based cohort study using data from the UK Biobank. PATIENTS: The study included 181,058 women of white ethnicity born in England between 1937 and 1970, among which 1,131 had an MS diagnosis. INTERVENTION: Oral contraceptive use, considering the self-reported age of initiation and discontinuation. The exposures of interest include the following: ever-use, current use, duration of current use in years, and age and year at initiation. MAIN OUTCOME MEASURES: Multiple sclerosis diagnosis (International Classification of Disease, 10th revision: G35) was used as an outcome of interest, and the associations with the exposures of interest were investigated using marginal structural models with a time-to-event approach. To adjust for confounding, we included in the models several variables, including MS polygenic risk score, education level, parity, smoking, fertility problems, obesity, and mononucleosis. We further aimed to evaluate the influence of parity using a mediation analysis. RESULTS: The association of both ever and current OC use did not result in a statistically significant MS hazard increase (ever vs. never-users, hazard ratio [HR] = 1.30 [95% confidence interval {CI}: 0.93,1.82]; current vs. never-users, HR = 1.35 [95% CI: 0.81, 2.25]). However, we highlighted parity as an effect modifier for this association. In nulliparous women, ever and current use resulted in a significant twofold and threefold MS hazard increase (HR = 2.08 [95% CI: 1.04, 4.17] and HR = 3.15 [95% CI: 1.43, 6.9]). These associations were supported by significant MS hazard increases for a higher duration of current use and for an earlier age at initiation. We further highlighted genetic MS susceptibility as another effect modifier, as a stronger OC-MS hazard association was found in women with a low MS polygenic risk score. CONCLUSION: Our findings highlighted how the association between OC use and MS varies on the basis of individual characteristics such as parity and genetic MS susceptibility. Importantly, current use in nulliparous women was found to be associated with a threefold increase in MS hazard. We acknowledge the need for cautious causal interpretation and further research to validate these findings across diverse populations and OC types.
