Objective To identify potential quality risks of Xiaoer Huatan Zhike Granules(Pediatric Phlegm-Resolving and Cough-Relieving Granules)through National Drug Sampling and Inspection,evaluate their overall quality,and propose improvements to the quality standards.Methods Samples from 34 manufacturers were tested using official standards.Exploratory methods were developed to enhance risk analysis,including thin-layer chromatography(TLC)identification,content uniformity testing,quantitative assays,and screening for unauthorized additives(e.g.,colorants).Results All batches met the official standards(100.0%compliance rate).However,deficiencies were observed:most manufacturers lacked controls for ephedrine hydrochloride content uniformity and quantification,omitted key ingredient identifications(e.g.,herbal components),and exhibited insufficient TLC specificity(e.g.,TLC of Ipecac tincture showed only one spot instead of multiple alkaloid-specific spots).Exploratory studies revealed risks in total emetine/cephaeline content,morroniside A/platycodin D content,ephedrine hydrochloride uniformity,and unauthorized colorant addition.Conclusions The overall quality of this variety is good,but the enterprise should improve the quality control measures throughout the entire process and establish stricter internal control standards;The official standards,unchanged for approximately 30 years,fail to address current regulatory requirements.The statutory quality standards need to be revised and improved.Qualitative or quantitative indicators for all drug flavors in the prescription should be added,and the content uniformity inspection of ephedrine hydrochloride should be increased.

Objective:To investigate the effects of different doses of rosuvastatin on lipid metabolism and left ventricular function in patients with type 2 diabetes mellitus (T2DM) accompanied by coronary heart disease (CHD).Methods:A prospective study was conducted involving 63 patients with T2DM accompanied by CHD who were treated at Jinan 2 nd People's Hospital and The Fifth People's Hospital of Jinan from January 2022 to June 2023. In a randomized case-control study, patients were assigned to either a control group ( n = 31, receiving 10 mg/d of rosuvastatin) or an observation group ( n = 32, receiving 20 mg/d of rosuvastatin) using a random number table method. After 8 weeks of treatment, the therapeutic effects were evaluated, and blood lipid levels and left ventricular function were recorded before and after treatment. Plasma levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP), homocysteine (Hcy), C-reactive protein (CRP), and the distance covered in a 6-minute walk test were compared between the two groups. Patients were followed for 1 year to monitor adverse reactions and the occurrence of adverse cardiovascular events. Results:The effective treatment rate in the observation group was significantly higher than that in the control group [90.63% (29/32) vs. 70.97% (22/31), χ2 = 3.95, P < 0.05). Prior to treatment, there were no statistically significant differences between the two groups regarding blood lipid levels, cardiac ultrasound indicators, serum levels of NT-proBNP, Hcy, and CRP, the distance covered in the 6-minute walk test, and the incidences of adverse reactions and adverse cardiovascular events (all P > 0.05). After treatment, both groups showed a reduction in total cholesterol and low-density lipoprotein cholesterol (both P < 0.05), with the observation group demonstrating significantly lower levels ( t = 10.54, 14.01, both P < 0.001). Additionally, both groups showed an increase in high-density lipoprotein cholesterol ( P < 0.05), but the observation group achieved significantly higher levels ( t = -14.07, P < 0.001). Both groups also exhibited an increase in left ventricular ejection fraction ( P < 0.05), with a greater improvement in the observation group ( t = -2.34, P < 0.05). The left ventricular end-diastolic diameter decreased in both groups ( P < 0.05), but the observation group had a smaller diameter ( t = 2.78, P < 0.05). Levels of NT-proBNP, Hcy, and CRP decreased in both groups (all P < 0.05), with the observation group showing significantly lower levels ( t = 6.55, 3.94, 6.38, all P < 0.001). Finally, the distance covered in the 6-minute walk test increased in both groups ( P < 0.05), with the observation group covering a greater distance ( t = -4.32, P < 0.001). Conclusions:High-dose rosuvastatin can effectively improve lipid metabolism and left ventricular function in patients with T2DM complicated by CHD. It significantly reduces levels of NT-proBNP, Hcy, and CRP, enhances exercise capacity, and demonstrates high safety, indicating a high potential for clinical application.

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

Gene therapy, harnessing the power of CRISPR-Cas9 and/or DNAzyme systems, stands as a pivotal approach in cancer therapy, enabling the meticulous manipulation of genes pivotal to tumorigenesis and immunity. However, the pursuit of precise gene therapy encounters formidable hurdles. Herein, a near-infrared upconversion theranostic nanomachine is devised and tailors for CRISPR-Cas9/DNAzyme systems mediate precise gene therapy. An ingenious logic DNAzyme system consists of Chain 1 (C1)/Chain 2 (C2) and endogenous lncRNA is designed. We employ manganese modified upconversion nanoparticles for carrying ultraviolet-responsive C1-PC linker-C2 (C₂P) chain and Cas9 ribonucleoprotein (RNP), with outermost coats with hyaluronic acid. Upon reaching tumor microenvironment (TME), the released Mn²⁺ ions orchestrate a trifecta: facilitating endosomal escape, activating cGAS-STING signaling, and enabling T1-magnetic resonance imaging. Under near-infrared irradiation, Cas9 RNP/C₂P complex dissociates, releasing Cas9 RNP into the nucleus to perform gene editing of Ptpn2, while C1/C2 chains self-assemble with endogenous lncRNA to form a functional DNAzyme system, targeting PD-L1 mRNA for gene silencing. This strategy remodels the TME by activating cGAS-STING signaling and dual immune checkpoints blockade, thus realizing tumor elimination. Our theranostic nanomachine armed with the CRISPR-Cas9/DNAzyme logic systems, represents a resourceful and promising strategy for advancing cancer systemic immunotherapy and precise gene therapy.

Objective:To establish the normal reference value of the left ventricular remodeling index（RI）in healthy adults，and to evaluate the phenotypes of RI in various left ventricular geometries and its relationship with left ventricular systolic and diastolic functions in asymptomatic hypertensive patients.Methods:A retrospective study design was employed，906 healthy Han Chinese volunteers were selected as the control group from the multicenter study "Echocardiographic Measurements in Normal Chinese Adults"（EMINCA），which was conducted in 2012. The normal reference range of left ventricular RI was established based on the 95% CI（ xˉ ± 1.96 s）. Statistical analyses were conducted to evaluate differences in RI across age groups and between genders. A total of 340 asymptomatic hypertensive patients in the Department of Health Management，Sichuan Provincial People's Hospital from July 2023 to March 2024 were prospectively included as the hypertension group. Conventional echocardiography and two-dimensional speckle tracking imaging were used to assess left ventricular structure and function. Parameters such as left ventricular mass index（LVMI），RI，relative wall thickness（RWT），the ratio of early diastolic mitral inflow velocity to the average early diastolic mitral annular velocity（E/e'），and the ratio of early diastolic to late diastolic mitral inflow velocities（E/A）were calculated. Differences of these parameters between the hypertension group and the healthy control group were compared. The hypertension group was stratified into 3 subgroups based on left ventricular posterior wall thickness at end-diastole（LVPWd）and RI：the non-LV hypertrophy group，the left ventricular hypertrophy with normal RI group，and the left ventricular hypertrophy with low RI group. Relevant parameters were compared among these subgroups，and the statistical significance of the differences was analyzed. Pearson correlation analysis and multiple linear regression analysis were performed to explore the relationships between left ventricular RI and GLS，LVEF，the average mitral annular peak systolic velocity（s'），e'，E/e'，E/A. Results:In the healthy control group，RI showed a declining trend with increasing age in both sexes. Furthermore，the RI was significantly higher in the female group compared to the male group（ P<0.001）. Compared with the healthy control group，LVMI and E/e' increased while RI，e' and s' decreased in the hypertension group（all P < 0.001）. Among the 3 subgroups of the hypertension group，compared with the other two groups，LVMI and Ｅ/e' increased while absolute GLS and s' reduced in the left ventricular hypertrophy with low RI subgroup（all P <0.001）. Pearson correlation analysis revealed that RI was negatively correlated with GLS and E/e'（ r=-0.457，-0.281；all P < 0.001），and positively correlated with LVEF，e'，s' and E/A（ r=0.229，0.394，0.150，0.172；all P < 0.05）. Multivariate linear regression analysis demonstrated that left ventricular RI was independently associated with GLS，LVEF，e'，s'，E/e' and E/A. Conclusions:The normal reference range of left ventricular RI tends to decrease with age and is typically higher in females than in males. In asymptomatic patients with primary hypertension，RI，systolic and diastolic functions of the left ventricular are lower，while LVMI is higher. Among these patients，functional impairment is more pronounced in patients with left ventricular hypertrophy and reduced RI. This indicates that left ventricular RI may offer an imaging basis for further classification and stratification of structural and functional abnormalities in the left ventricle of asymptomatic hypertensive patients.

Objective To analyze the difference of diseases between the coal mine workers and the general population inpatients by the disease spectrum in Datong City. Methods A total of 282 639 hospitalized patients in Datong City in 2023 were included as the study subjects. Participants were divided into a general population group and a coal mine workers group based on health insurance types, with 247 897 and 34 742 cases, respectively. The disease spectrum of participants in both groups was coded and analyzed according to the International Statistical Classification of Diseases and Related Health Problems, 10th Revision (ICD-10). The standardized constituent ratios of disease categories were calculated and compared between the two groups. Results Patients aged 60-<70 years had the largest standardized proportion in both cohorts (29.02% in the general population group and 33.08% in coal mine workers group). Circulatory system diseases had the highest standardized proportion in both groups. Within the top six disease categories ranked by standardized composition ratio in the coal mine workers, three demonstrated a higher burden, including neoplasms (C00-D48), symptoms, signs and abnormal clinical/laboratory findings not elsewhere classified (R00-R99), and factors influencing health status/contact with health services (Z00-Z99), compared with the general population (11.82% vs 10.44%, 12.99% vs 8.03%, and 6.17% vs 2.04%, respectively). In both groups, male workers had higher standardized constituent ratios of circulatory, respiratory, and digestive system diseases than females (coal mine workers group, 19.53% vs 14.31%, 13.56% vs 9.10%, 10.61% vs 8.43%; general population group, 26.15% vs 22.42%, 15.45% vs 11.87%, 11.52% vs 10.41%). Conversely, the ratios for conditions classified under symptoms, signs and abnormal clinical/laboratory findings not elsewhere classified (R00-R99). and factors influencing health status/contact with health services (Z00-Z99) were higher in females than males (coal mine workers group, 13.31% vs 12.68%, 7.26% vs 5.13%; general population group, 8.91% vs 7.18%, 2.35% vs 1.74%). Mental and behavioral disorders (F00-F99) were most prevalent in the 22-<50-year age group in the general population (9.92%) and in the 50-<60-year age group in coal mine workers (8.58%). The standardized proportion of respiratory system diseases ranked first in≥80-year age workers in general population group and coal mine workers group (29.54% and 26.46%, respectively). Regarding specific malignancies, unspecified malignant neoplasm of the bronchus or lung was the most common cancer among males in both groups (3.44% and 3.62%). Among females, the standardized proportion of unspecified malignant neoplasm of breast was higher in coal mine workers group than in the general population group (2.60% vs 2.09%). Conclusion Neoplasms, abnormal symptoms, and mental health disorders should be prioritized in disease prevention strategies for coal mine workers. Greater attention should be paid to mental health screening in younger populations, and medical resource allocation should be optimized according to sex-specific high-incidence cancers.
