ObjectiveTo establish the fingerprints of 15 batches of Hengzhi Kechuan capsules， to quantitatively analyze 10 index components， and to evaluate the quality uniformity of samples from different batches. MethodsThe fingerprints and quantitative analysis of Hengzhi Kechuan capsules were established by a combination method of high performance liquid chromatography coupled with diode array detector and charged aerosol detector（HPLC-DAD-CAD）， adenosine， guanosine， vanillic acid， safflomin A， agarotetrol， naringin， hesperidin， militarine， ginsenoside Rb₁， and glycyrrhizic acid were selected as quality attribute indexes. A total of 15 batches of Hengzhi Kechuan capsules from 2022 to 2024（3 boxes per batch） were qualitatively and quantitatively analyzed， and the quality uniformity level of the manufacturers was characterized by parameters of intra-batch consistency（P_A） and inter-batch consistency（P_B）. The homogeneity and difference of quality attribute indexes of samples from different years were analyzed by heatmap clustering analysis. ResultsHPLC fingerprints and quantitative method of Hengzhi Kechuan capsules were established， and the methods could be used for qualitative and quantitative analysis of this preparation， which was found to be stable and reliable by method validation. The similarity of fingerprints of 15 batches of samples was 0.887-0.975， a total of 13 common peaks were calibrated， and 10 common peaks were designated， all of which were quality attribute index components. The results of quantitative analysis showed that the contents of the above 10 ingredients in the samples were 0.038-0.078， 0.115-0.251， 0.007-0.018， 0.291-0.673， 0.122-0.257， 0.887-1.905， 1.841-3.364， 1.412-2.450， 2.207-3.112， 0.650-1.161， respectively. And the contents of ginsenoside Rb₁ and glycyrrhizic acid met the limit requirements in the 2020 edition of Chinese Pharmacopoeia. For the samples from 15 batches， the P_A values of the 10 index components were all <10%， indicating good intra-batch homogeneity， and the P_B values ranged from 33.86% to 92.97%， suggesting that the inter-batch homogeneity was poor. Heatmap clustering analysis showed that the samples from different years were clustered into separate categories， and adenosine， guanosine， safflomin A， naringin， hesperidin and agarotetrol were the main differential components. ConclusionThe intra-annual quality uniformity of Hengzhi Kechuan capsules is good and the inter-annual quality uniformity is insufficient， which may be related to the quality difference of Pinellinae Rhizoma Praeparatum， Carthami Flos， Citri Sarcodactylis Fructus， Citri Reticulatae Pericarpium， Aquilariae Lignum Resinatum， Citri Fructus， etc. In this study， the fingerprint and multi-indicator determination method of Hengzhi Kechuan capsules was established， which can be used for more accurate and efficient quality control and standardization enhancement.

Abstract Postoperative urinary retention is a common complication after mixed hemorrhoid surgery, referring to the inability of urine in the bladder to be normally expelled, leading to urine retention. This condition not only prolongs the postoperative recovery time and increases medical costs, but may also cause problems such as urinary tract infections and bladder dysfunction. The pathogenesis of urinary retention after mixed hemorrhoid surgery is complex, involving multiple factors such as the type of surgery, anesthesia method, individual differences among patients, postoperative pain management and psychological stress. Although there are various clinical treatment methods, their efficacy varies among individuals. This article reviews relevant literature from 2018 to 2024, analyzing the etiology of urinary retention after mixed hemorrhoid surgery. It summarizes the intervention measures and mechanisms of non-pharmacological treatments, such as physical therapy and analgesic techniques, as well as pharmacological treatments, including anticholinesterase drugs, selective α-receptor blockers and analgesics drugs, so as to provide the reference for the prevention and treatment of urinary retention after mixed hemorrhoid surgery.

Objective To analyze the operation of Measles Surveillance System (MSS) in Hebei Province, and to provide evidence for measles elimination. Methods Measles surveillance data was collected from the MSS from 2020 to 2023, and a modified weighted technology for order preference by similarity to an ideal solution (TOPSIS) method was used to evaluate the surveillance indexes of measles in Hebei Province. Results The operation quality of the measles surveillance system in Hebei Province was improved year by year, with the highest quality in 2023, and all the indicators reached the monitoring program standards. The quality of measles surveillance system was not balanced among cities, and the main influencing factor was the substandard sensitivity indicators. The quality of measles surveillance system was the highest in Baoding City and the lowest in Zhangjiakou City. Conclusion The measles surveillance system in Hebei province is running well, and the sensitivity of the surveillance system should be improved to keep the high-quality operation of the surveillance system.

Objective: To analyze the effects of health literacy on overweight and obesity among primary school students and their parents in terms of salt, oil and sugar reduction (referred to as the "three reductions"), so as to provide a theoretical basis for the development of obesity control measures. Methods: From March to April 2024, a total of 1 022 fourthgrade primary school students and 913 parents were surveyed in 24 classes in six counties in Shandong Province using multistage cluster random sampling, and physical measurements of primary school students were conducted. Pearsons correlation analysis and ordered multivariate Logistic regression were used to investigate the associations between health literacy of primary school students and their parents with overweight and obesity among children. Results: The detection rates of overweight and obesity primary school students in Shandong Province were 14.87% and 24.66%, respectively, with significant sex difference in obesity rate (29.46% for boys and 19.76% for girls) (χ2=12.93, P<0.01). In addition to students reducing oil scores, parental reducing salt,reducing oil,reducing sugar, comprehensive health literacy scores and students reducing salt,reducing sugar and comprehensive health literacy scores showed a negative relationship with students overweight and obesity (r=-0.10, -0.08, -0.07, -0.10, -0.04, -0.07, -0.03, P<0.05). The overweight and obesity rates among primary school students with high parental reducing salt,reducing oil,reducing sugar and composite health literacy scores were lower (OR=0.69, 0.69, 0.71, 0.63, P<0.05); and the overweight and obesity rate among students with high parental and low parental and high and low parental health literacy scores were lower (OR=0.68, 0.57, P<0.05). Conclusion Improving health literacy regarding "three reductions" for parents and children, especially parents, can effectively reduce the risk of childhood overweight and obesity.

To investigate the effect of HQC-containing serum on the viability of co-cultured cells， and the experiment was divided into the following groups based on the dilution concentration： blank group， 10% HQC group， 20% HQC group， and 30% HQC group.To study the influence of the optimal concentration of HQC-containing serum on cytokine and pathway indicators in each group， the experiment was divided into three groups： normal group， model group， and optimal concentration HQC-containing serum group.For the validation of the transfection efficiency of the CircRNA_0001543 interference plasmid， the experiment was divided into the following groups： blank group， si-NC group （with transfection reagent）， si-circ_0001543-1 group （with transfection reagent and interference plasmid No. 1 targeting circ_0001543）， si-circ_0001543-2 group （with transfection reagent and interference plasmid No. 2 targeting circ_0001543）， and si-circ_0001543-3 group （with transfection reagent and interference plasmid No. 3 targeting circ_0001543）.For the validation of the transfection efficiency of the CircRNA_0001543 overexpression plasmid， the experiment was divided into the following groups： blank group， OE-NC group （with transfection reagent）， and OE-circ_0001543 group （with transfection reagent and overexpression plasmid targeting circ_0001543）.To study the effects of CircRNA_0001543 interference/overexpression on cytokine and pathway indicators in each group， the experiment was divided into the following groups： si-NC group， si-CircRNA_0001543 group， OE-NC group， and OE-CircRNA_0001543 group. Enzyme-linked immunosorbent assay （ELISA） was used to detect levels of interleukin-1β （IL-1β）， IL-10， IL-37， and tumor necrosis factor-α （TNF-α）. Real-time quantitative polymerase chain reaction （Real-time PCR） was utilized to measure the expression of CircRNA_0001543， IκBα， and NF-κB p65. ResultsAfter 48 hours， 30% Huangqin Qingre Chubi Capsules-containing serum significantly inhibited the proliferation of co-cultured PBMCs and FLSs， which was determined to be the optimal experimental drug-containing serum concentration. Compared with those in the normal group， the expressions of NF-κB p65 mRNA， IκBα mRNA， IL-1β， and TNF-α in the model group were significantly increased （P<0.01）， while the expressions of CircRNA_0001543 mRNA， IL-10， and IL-37 were significantly decreased （P<0.01）. Compared with those in the model group， the expressions of NF-κB p65 mRNA， IκBα mRNA， IL-1β， and TNF-α in the Huangqin Qingre Chubi Capsules-containing serum group were significantly decreased （P<0.05）， and the expressions of CircRNA_0001543 mRNA， IL-10， and IL-37 were significantly increased （P<0.05）， with the most prominent changes in the 30% drug-containing serum group （P<0.01）. Compared with that in the si-NC group， the expression of CircRNA_0001543 was significantly reduced in the si-CircRNA_0001543 group （P<0.01）. Compared with that in the OE-NC group， the expression of CircRNA_0001543 was significantly increased in the OE-CircRNA_0001543 group （P<0.01）， indicating that the si-CircRNA_0001543 and OE-CircRNA_0001543 plasmids were successfully transfected. Based on the optimal drug-containing serum of Huangqin Qingre Chubi Capsules， si-CircRNA_0001543 transfection led to significantly increased expressions of NF-κB p65 mRNA， IκBα mRNA， IL-1β， and TNF-α and decreased the expressions of IL-10 and IL-37 （P<0.01）. In contrast， OE-CircRNA_0001543 transfection significantly decreased the expressions of NF-κB p65 mRNA， IκBα mRNA， IL-1β， and TNF-α （P<0.01） and increased the expressions of IL-10 and IL-37 （P<0.01）. ConclusionHuangqin Qingre Chubi capsules-containing serum can improve immune inflammation in AS by increasing the expression of CircRNA_0001543， regulating the NF-κB pathway， suppressing pro-inflammatory cytokines， and enhancing anti-inflammatory cytokine expression.

OBJECTIVE: To investigate the effects of Danmu Extract Syrup (DMS) on lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice and explore the mechanism. METHODS: Seventy-two male Balb/C mice were randomly divided into 6 groups according to a random number table (n=12), including control (normal saline), LPS (5 mg/kg), LPS+DMS 2.5 mL/kg, LPS+DMS 5 mL/kg, LPS+DMS 10 mL/kg, and LPS+Dexamethasone (DXM, 5 mg/kg) groups. After pretreatment with DMS and DXM, the ALI mice model was induced by LPS, and the bronchoalveolar lavage fluid (BALF) were collected to determine protein concentration, cell counts and inflammatory cytokines. The lung tissues of mice were stained with hematoxylin-eosin, and the wet/dry weight ratio (W/D) of lung tissue was calculated. The levels of tumor necrosis factor-α (TNF-α), interleukin (IL)-6 and IL-1 β in BALF of mice were detected by enzyme linked immunosorbent assay. The expression levels of Claudin-5, vascular endothelial (VE)-cadherin, vascular endothelial growth factor (VEGF), phospho-protein kinase B (p-Akt) and Akt were detected by Western blot analysis. RESULTS: DMS pre-treatment significantly ameliorated lung histopathological changes. Compared with the LPS group, the W/D ratio and protein contents in BALF were obviously reduced after DMS pretreatment (P<0.05 or P<0.01). The number of cells in BALF and myeloperoxidase (MPO) activity decreased significantly after DMS pretreatment (P<0.05 or P<0.01). DMS pre-treatment decreased the levels of TNF-α, IL-6 and IL-1 β (P<0.01). Meanwhile, DMS activated the phosphoinositide 3-kinase/protein kinase B (PI3K/Akt) pathway and reversed the expressions of Claudin-5, VE-cadherin and VEGF (P<0.01). CONCLUSIONS DMS attenuated LPS-induced ALI in mice through repairing endothelial barrier. It might be a potential therapeutic drug for LPS-induced lung injury.
