Objective: To compare the Reveos automated blood processing system with the current method, and to evaluate the feasibility and validity of using the Reveos system for blood component preparation. Methods: Forty units of 400 mL whole blood samples were divided into two groups: 2C group (for two-component preparation) and 3C group (for three-component preparation). Each group was further divided into a Reveos subgroup and a control subgroup. Blood components were prepared using the Reveos system and the current centrifugation method respectively. The 2C group yielded suspended red blood cells and plasma, while the 3C group yielded suspended red blood cells, plasma, and platelets. Key quality indicators for red blood cells, plasma, and platelets were measured before and after separation. Inter-group differences were analyzed using SPSS 25.0. Results: The trend of changes in the main performance indicators of red blood cells, plasma, and platelets before and after separation was generally consistent between the Reveos group and the control group, with no significant differences for most performance indicators. The Reveos system outperformed the current method in several aspects: in the 3C group, the hematocrit (Hct) was significantly higher in the Reveos group than in the control group [(62.82%±1.64%) vs (53.62%±3.04)%, P<0.001]; the white blood cell count in red blood cell suspensions was significantly lower than that in the control group [(3.37±1.42)×10
/L vs (8.42±2.30)×10
/L, P<0.001]; plasma yield was 27.5% higher than that in the control group [(183.90±17.37) mL vs (144.28±20.53) mL, P<0.001]; and the platelet activation rate was significantly lower than that in the control group [(21.97±14.25)% vs (34.73±11.92)%, P=0.044]. Conclusion: The Reveos system demonstrates good consistency with the current method in preparing blood components, and outperforms the current method in terms of leukocyte reduction and red blood cell concentration.

ObjectiveTo evaluate the clinical efficacy and economic value of the Jiangsu Traditional Chinese Medicine (TCM) Diagnosis and Treatment Protocol for Dominant Diseases (abbreviated as the Diagnosis and Treatment Protocol) in adult patients with non-severe community-acquired pneumonia (CAP) based on real-world clinical data. MethodsA retrospective real-world cohort study was conducted using electronic medical records of adult patients hospitalized for non-severe CAP from September 1st, 2023 to December 31st, 2024 across 10 TCM hospitals in Jiangsu province. Patients were classified into an exposure group and a non-exposure group based on whether they received Chinese herbal medicine (CHM) according to the Diagnosis and Treatment Protocol. The non-exposure group received only conventional western medicine, while the exposure group additionally received differentiated CHM for at least five consecutive days. Outcomes were compared between two patient groups, including cough resolution rate, sputum resolution rate (assessed by volume, color, and consistency), incidence of abnormal C-reactive protein (CRP), incidence of abnormal white blood cell (WBC) count, and radiographic resolution rate of pulmonary infiltrates on chest imaging. Multivariable logistic regression was performed to identify factors influencing clinical efficacy. Subgroup analyses were conducted according to age, gender, smoking status, history of hypertension, and pneumonia severity score (CURB-65), and the efficacy of treatment for cough and sputum was analyzed within each subgroup. Cost-effectiveness analysis was conducted using cough resolution rate as the outcome measure, evaluating the pharmacoeconomics of the two groups. ResultsA total of 1688 patients were included with 1293 in the exposure group and 395 in the non-exposure group. Compared to the non-exposure group, the exposure group demonstrated significantly higher resolution rates of cough, sputum volume, color, and consistency, as well as a significantly lower incidence of abnormal CRP (P<0.05). No statistically significant difference was observed between the groups in terms of abnormal WBC count and radiographic resolution rate of pulmonary infiltrates (P>0.05). Logistic regression analysis showed that the cough resolution rate in the exposure group was 1.83 times that of the non-exposure group, while the probabilities of resolution in sputum volume, color, and consistency were 1.37, 2.09, and 1.56 times those of the non-exposure group, respectively (P<0.05). Subgroup analyses showed that the exposure group achieved significantly higher cough resolution rates across most subgroups except for populations with a CURB-65 score ≥2 or those with a history of hypertension (P<0.05). Specifically, among females, patients aged ≥18 and <65 years, non-smokers, those without hypertension, and those with a CURB-65 score of 0, the exposure group showed a higher cough resolution rate than the non-exposure group (P<0.05). From an economic perspective, total hospitalization cost, length of stay, antibiotic cost, and CHM cost all differed significantly between groups (P<0.05). The cost-effectiveness ratio (CER) was 10,788.80 CNY/case in the exposure group, while 22,513.80 CNY/case in the non-exposure group. This implies that, compared with the exposure group, the non-exposure group incurred an additional 17,302.27 CNY to achieve one case of cough resolution. When the willingness-to-pay threshold ranged from 0 to 50,000 CNY, the probability of economic advantage was consistently higher in the exposure group than in the non-exposure group. ConclusionOn the basis of conventional western medicine, the addition of CHM in accordance with the Diagnosis and Treatment Protocol can effectively improve clinical symptoms, reduce inflammatory markers, promote clinical recovery, and is more cost-effective in treating adults with non-severe CAP.

ObjectiveTo observe the real‑world effectiveness and economic outcomes of Weishi Qingjin Formula (苇石清金方, WQF) in the treatment of adult community‑acquired pneumonia (CAP) with phlegm‑heat obstructing the lung syndrome. MethodsBased on a multicenter, real-world retrospective cohort study, clinical data were collected from hospitalized adult patients diagnosed with non‑severe CAP and phlegm‑heat obstructing the lung syndrome in 10 traditional Chinese medicine (TCM) hospitals in Jiangsu province. Patients were divided into an exposure group (those who received oral WQF) and a non‑exposure group (those who did not). The following outcomes were compared between the two groups before and after treatment, which were remission rates of clinical symptoms including cough, expectoration (sputum volume, color, consistency), and chest pain, levels of inflammatory markers including C‑reactive protein (CRP) and white blood cell count (WBC), and the rate of pulmonary inflammatory absorption on chest CT. Subgroup analyses were performed based on age, gender, smoking status, presence of hypertension, and the severity of community-acquired pneumonia (CURB‑65) score, comparing the two groups in terms of cough remission rate, chest pain remission rate, and chest CT absorption rate. For health economic evaluation, cost‑effectiveness analysis was used to calculate the cost‑effectiveness ratio (CER) and incremental cost‑effectiveness ratio (ICER). Univariate sensitivity analysis and probabilistic sensitivity analysis were performed to test the robustness of the results. ResultsA total of 647 patients in the exposure group and 1491 patients in the non-exposure group were included in the final statistical analysis. There was no statistically significant difference in length of hospital stay, gender, marital status, smoking history, bronchoscopy history, and comorbidities between the groups (P>0.05), but age, CURB-65 score, and antibiotic use. The exposure group had significantly higher remission rates of cough and sputum consistency than the non-exposure group (P<0.05). After adjusting for confounders using propensity score matching and logistic regression, the cough remission rate in the exposure group was 1.49 times that of the non-exposure group (P<0.01). No significant difference was observed between groups in the reduction rates of CRP and WBC, and in the rate of pulmonary inflammatory absorption on chest CT (P>0.05). Subgroup analyses revealed that the cough remission rate in the exposure group was significantly better than that in the non-exposure group except for patients aged ≥65 years, smokers, hypertensive patients, those using other type antibiotics or not using antibiotics, and those with a CURB-65 score ≥1 (P<0.05). Among smokers, the chest pain remission rate in the exposure group was 4.38 times that of the non-exposure group (P<0.01). No significant difference in chest CT absorption rate was found between groups across subgroups of gender, age, hypertension status, or antibiotic type (P>0.05). In terms of economic evaluation, CER was 10,877.60 CNY/case in the exposure group and 16,773.10 CNY/case in the non-exposure group. Compared to the exposure group, the non-exposure group incurred an additional 15,034.26 CNY to achieve one case of cough resolution, indicating a more favorable cost-effectiveness profile. Probabilistic sensitivity analysis yielded results consistent with the cost-effectiveness analysis, confirming the robustness of the findings. ConclusionWQF demonstrates significant efficacy in improving cough symptoms in the treatment of adult CAP with phlegm-heat obstructing the lung syndrome, and also exhibits favorable economic benefits.

Triple-negative breast cancer (TNBC) represents a distinctive subtype, characterized by the absence of estrogen receptors, progesterone receptors, and human epidermal growth factor receptor 2 (HER2). Due to its high inter-tumor and intra-tumor heterogeneity, TNBC poses significant chanllenges for personalized diagnosis and treatment. The advant of clustered regular interspaced short palindromic repeats (CRISPR) technology has profoundly enhanced our understanding of the structure and function of the TNBC genome, providing a powerful tool for investigating the occurrence and development of diseases. This review focuses on the application of CRISPR/Cas technology in the personalized diagnosis and treatment of TNBC. We begin by discussing the unique attributes of TNBC and the limitations of current diagnostic and treatment approaches: conventional diagnostic methods provide limited insights into TNBC, while traditional chemotherapy drugs are often associated with low efficacy and severe side effects. The CRISPR/Cas system, which activates Cas enzymes through complementary guide RNAs (gRNAs) to selectively degrade specific nucleic acids, has emerged as a robust tool for TNBC research. This technology enables precise gene editing, allowing for a deeper understanding of TNBC heterogeneity by marking and tracking diverse cell clones. Additionally, CRISPR facilitates high-throughput screening to promptly identify genes involved in TNBC growth, metastasis, and drug resistance, thus revealing new therapeutic targets and strategies. In TNBC diagnostics, CRISPR/Cas was applied to develop molecular diagnostic systems based on Cas9, Cas12, and Cas13, each employing distinct detection principles. These systems can sensitively and specifically detect a variety of TNBC biomarkers, including cell-specific DNA/RNA and circulating tumor DNA (ctDNA). In the realm of precision therapy, CRISPR/Cas has been utilized to identify key genes implicated in TNBC progression and treatment resistance. CRISPR-based screening has uncovered potential therapeutic targets, while its gene-editing capabilities have facilitated the development of combination therapies with traditional chemotherapy drugs, enhancing their efficacy. Despite its promise, the clinical translation of CRISPR/Cas technology remains in its early stages. Several clinical trials are underway to assess its safety and efficacy in the treatment of various genetic diseases and cancers. Challenges such as off-target effects, editing efficiency, and delivery methods remain to be addressed. The integration of CRISPR/Cas with other technologies, such as 3D cell culture systems, human induced pluripotent stem cells (hiPSCs), and artificial intelligence (AI), is expected to further advance precision medicine for TNBC. These technological convergences can offer deeper insights into disease mechanisms and facilitate the development of personalized treatment strategies. In conclusion, the CRISPR/Cas system holds immense potential in the precise diagnosis and treatment of TNBC. As the technology progresses and becomes more costs-effective, its clinical relevance will grow, and the translation of CRISPR/Cas system data into clinical applications will pave the way for optimal diagnosis and treatment strategies for TNBC patients. However, technical hurdles and ethical considerations require ongoing research and regulation to ensure safety and efficacy.

Dry eye disease (DED) is a prevalent and intractable ocular disease induced by a variety of causes. Elevated sphingomyelin (SM) levels and pro-inflammatory cytokines were detected on the ocular surface of DED patients, particularly in the meibomian glands. Sphingomyelin synthase 2 (SMS2), one of the proteins involved in SM synthesis, would light a novel way of developing a DED therapy strategy. Herein, we report the design and optimization of a series of novel thiophene carboxamide derivatives to afford 14l with an improved highly potent inhibitory activity on SM synthesis (IC50, SMS2 = 28 nmol/L). Moreover, 14l exhibited a notable protective effect of anti-inflammation and anti-apoptosis on human corneal epithelial cells (HCEC) under TNF-α-hyperosmotic stress conditions in vitro, with an acceptable ocular specific distribution (corneas and meibomian glands) and pharmacokinetics (PK) profiles (t 1/2, cornea = 1.11 h; t 1/2, meibomian glands = 4.32 h) in rats. Furthermore, 14l alleviated the dry eye symptoms including corneal fluorescein staining scores and tear secretion in a dose-dependent manner in mice. Mechanically, 14l reduced the mRNA expression of Tnf-α, Il-1β and Mmp-9 in corneas, as well as the proportion of very long chain SM in meibomian glands. Our findings provide a new strategy for DED therapy based on selective SMS2 inhibitors.

ObjectiveBased on the concept of quality by design(QbD), the processing process of calcined Pyritum was optimized, and its X-ray diffraction(XRD) fingerprint was established. MethodsThe safety, effectiveness and quality controllability of calcined Pyritum were taken as the quality profile(QTPP), the color, hardness, metallic luster, phase composition, the contents of heavy metals and hazardous elements were taken as the critical quality attributes(CQAs), and the calcination temperature, calcination time, paving thickness and particle size were determined as the critical process parameters(CPPs). Differential thermal analysis, X-ray diffraction(XRD) and inductively coupled plasma mass spectrometry(ICP-MS) were used to analyze the correlation between the calcination temperature and CQAs of calcined Pyritum. Then, based on the criteria importance through intercriteria correlation(CRITIC)-entropy weight method, the optimal processing process of calcined Pyritum was optimized by orthogonal test. Powder XRD was used to analyze the phase of calcined Pyritum samples processed according to the best process, and the mean and median maps of calcined Pyritum were established by the superposition of geometric topological figures, and similarity evaluation and cluster analysis were carried out. ResultsThe results of single factor experiments showed that the physical phase of Pyritum changed from FeS2 to Fe7S8 during the process of temperature increase, the color gradually deepened from dark yellow, and the contents of heavy metals and harmful elements decreased. The optimized processing process of calcined Pyritum was as follows:calcination temperature at 750 ℃, calcination time of 2.5 h, paving thickness of 3 cm, particle size of 0.8-1.2 cm, vinegar quenching 1 time[Pyritum-vinegar(10∶3)]. After calcination, the internal structure of Pyritum was honeycomb-shaped, which was conducive to the dissolution of active ingredients. XRD fingerprints of 13 batches of calcined Pyritum characterized by 10 common peaks were established. The similarities of the relative peak intensities of the XRD fingerprints of the analyzed samples were>0.96, and it could effectively distinguish the raw products and unqualified products. ConclusionTemperature is the main factor affecting the quality of calcined Pyritum. After processing, the dissolution of the effective components in Pyritum increases, and the contents of heavy metals and harmful substances decrease, reflecting the function of processing to increase efficiency and reduce toxicity. The optimized processing process is stable and feasible, and the established XRD fingerprint can be used as one of the quality control standards of calcined Pyritum.
