OBJECTIVE To investigate the effect and mechanism of Jingangteng capsules in the treatment of non-alcoholic fatty liver disease （NAFLD）. METHODS Thirty-two SD rats were randomly divided into normal group and modeling group. The modeling group was fed a high-fat diet to establish a NAFLD model. The successfully modeled rats were then randomly divided into model group， atorvastatin group[positive control， 2 mg/（kg·d）]， and Jingangteng capsules low- and high-dose groups [0.63 and 2.52 mg/（kg·d）]， with 6 rats in each group. The pathological changes of the liver were observed by hematoxylin-eosin staining and oil red O staining. Enzyme-linked immunosorbent assay was performed to determine the serum levels of triglycerides （TG）， total cholesterol （TC）， high-density lipoprotein cholesterol （HDL-C）， low-density lipoprotein cholesterol （LDL-C）， alanine transaminase （ALT）， aspartate transaminase （AST）， tumour necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， IL-6， IL-18. 16S rDNA amplicon sequencing and metabolomics techniques were applied to explore the effects of Jingangteng capsules on gut microbiota and metabolisms in NAFLD rats. Based on the E-mail：591146765@qq.com metabolomics results， Western blot analysis was performed to detect proteins related to the nuclear factor kappa-B （NF-κB）/NOD-like receptor family protein 3 （NLRP3） signaling pathway in the livers of NAFLD rats. RESULTS The experimental results showed that Jingangteng capsules could significantly reduce the serum levels of TG， TC， LDL-C， AST， ALT， TNF-α， IL-1β， IL-6， IL-18， while increased the level of HDL-C， and alleviated the hepatic cellular steatosis and inflammatory infiltration in NAFLD rats. They could regulate the gut microbiota disorders in NAFLD rats， significantly increased the relative abundance of Romboutsia and Oscillospira， and significantly decreased the relative abundance of Blautia （P＜0.05）. They also regulated metabolic disorders primarily by affecting secondary bile acid biosynthesis， fatty acid degradation， O-antigen nucleotide sugar biosynthesis， etc. Results of Western blot assay showed that they significantly reduced the phosphorylation levels of NF-κB p65 and NF-κB inhibitor α， and the protein expression levels of NLRP3， caspase-1 and ASC （P＜0.05 or P＜0.01）. CONCLUSIONS Jingangteng capsules could improve inflammation， lipid accumulation and liver injury in NAFLD rats， regulate the disorders of gut microbiota and metabolisms， and inhibit NF-κB/NLRP3 signaling pathway. Their therapeutic effects against NAFLD are mediated through the inhibition of the NF-κB/NLRP3 signaling pathway.

OBJECTIVE To provide empirical basis for promoting the dynamic adjustment of the pharmaceutical care catalogue and the formulation of policies such as hierarchical payment of medical insurance. METHODS A multicenter cross- sectional survey method was adopted to conduct a questionnaire survey among 424 inpatients in 22 tertiary medical institutions in 12 prefecture-level cities of Hubei Province to evaluate their demand for pharmaceutical care， willingness to pay and preference for service forms. Combined with univariate and multivariate Logistic regression analysis， the influencing factors and key factors that affect patients’ willingness to pay for pharmaceutical care were identified. RESULTS Only 39.86% of the patients were aware of pharmaceutical care or pharmacists， and 89.62% of the patients hope to receive pharmaceutical care. Among the 16 types of pharmaceutical care， the patients surveyed had a relatively high recognition rate for guidance on drug usage and dosage， notification of medication precautions， and the identification， prevention and handling of adverse drug reactions. 96.70%， 95.30%， and 94.12% respectively expressed strong approval and approval. The demand for services such as insurance-related policy consultation， popular science on the mechanism of drug action， and assessment of the combined use of traditional Chinese and Western medicines was relatively low， with 61.65%， 68.47%， and 68.47% expressing strong approval and approval respectively. The positive influencing factors of willingness to pay were household monthly income ＞ 5 000 yuan （OR＝1.742）， awareness of pharmaceutical care or pharmacists （OR＝3.620）， and the desire to receive pharmaceutical care （OR＝4.686） （P＜0.05）， while self-rating health as “good” （OR＝0.390） was a negative influencing factor （P＜0.05）. Cardiovascular and cerebrovascular diseases （54.48%） and antihypertensive drugs （45.05%） were the service scenarios that the surveyed patients most hope to be covered. 85.14% of the patients preferred “service when xiaochnye@126.com needed”， with a single service duration of less than 10 minutes being appropriate （84.43%）， and the willingness to pay within 20 yuan being the main type （85.38%）. CONCLUSIONS Based on the characteristics of patients’ needs and payment behaviors， it is suggested that our country could consider establishing a hierarchical payment mechanism for pharmaceutical care， and focus on differentiated design in combination with diseases and medication situations. At the same time， the rights， responsibilities and service standards of resident pharmacists in the links such as medication reorganization and medical order review should be further clarified to comprehensively enhance the clinical value and policy operability of pharmaceutical care.

Glucagon-like peptide-1 ( GLP-1 ) is secreted by gut enteroendocrine cells. GLP-1 receptor agonists ( GLP-1 RAs) control glucose-related augmentation of insulin and suppress glu-cagon secretion. GLP-lRAs also inhibit gastric emptying, food intake and limit weight gain. In the past decade, significant progresses have been made in the investigation on the effects of GLP-1 RAs on cardiovascular system. The potential advantages of oral small-molecule GLP-1 RAs could improve the application of this class of drugs. This review highlights the multiple cardiovascular profiles of GLP-1 RAs in the treatment of cardiovascular diseases to provide new insights into cardiovascular benefits of GLP-1 RAs.

Objective To understand the epidemiological characteristics and current situation of pertussis in Hubei Province from 2016 to 2021. Methods Data on the incidence of pertussis and immunization history of cases in Hubei Province from 2016 to 2021 were collected and descriptive epidemiological analysis was conducted. Results From 2016 to 2021, a total of 1 236 pertussis cases were reported in Hubei Province, with an average annual reported incidence rate of 0.35/100 000. The average annual reported incidence of pertussis in the age group ≤ 5 years old was 6.22/100 000, and the age group <1 year old reported the highest annual incidence rate (21.51/100 000). The proportion of pertussis among preschool children and students had increased significantly since 2020. Among the 1 111 cases with a known immunization history, 17.55% were under the age of vaccination , 41.85% were not vaccinated, and 17.46% had completed the whole course of vaccination. Conclusion Since 2016, the incidence of pertussis in Hubei Province has been on the rise. The risk of pertussis is higher in infants and young children who have not reached the age of vaccination and who have not been vaccinated in time according to the immunization program after reaching the age of vaccination. The timeliness and vaccination rate of DTP vaccine should be improved to reduce the risk of pertussis in infants and young children. In addition, more attention should be paid to the prevalence of pertussis among preschool children and students.

ObjectiveTo explore the role and molecular mechanism of Weifuchun （WFC） in inhibiting inflammation and alleviating gastric precancerous lesions （GPL）. MethodHuman gastric mucosal epithelial cells （GES-1） were stimulated with N-methyl-N′-nitro-N-nitrosoguanidine （MNNG） for the modeling of GPL （MC cells）， with Caspase-3 inhibition by Z-DEVD-FMK. MC cells were divided into control （20% blank serum）， WFC （15% and 20% WFC-containing serum）， and caspase-3 inhibitor groups. The cell counting kit-8 （CCK-8） was used to examine the viability of GES-1 cells or MC cells. The Transwell assay and 5-acetylidene-2′-deoxyuridine （EdU） staining were employed to examine cell invasion and proliferation， respectively. Flow cytometry was employed to determine the level of reactive oxygen species. Real-time PCR was conducted to determine the mRNA levels of interleukin （IL）-1， IL-6， and tumor necrosis factor （TNF）-α. Gene Expression Omnibus （GEO） was used to analyze the role of pyroptosis in gastric cancer progression. Western blotting was employed to determine the protein levels of nuclear factor-κB （NF-κB） p65， gasdermin E （GSDME）， and Caspase-3. Immunofluorescence staining was employed to detect the NF-κB p65 protein level and nuclear translocation. Hematoxylin-eosin staining was carried out to observe the pathological changes in the gastric mucosa before and after WFC treatment in the patients. ResultCompared with the control group， MC cells presented enhanced proliferation and invasion energy （P<0.01）. Compared with the blank serum group， WFC-containing serum inhibited the proliferation and invasion of MC cells （P<0.01）， down-regulated the mRNA levels of IL-1， IL-6， and TNF-α， and lowered the level of reactive oxygen species （P<0.05， P<0.01）. The transcriptome data at different stages of gastric cancer showed that pyroptosis was involved in gastric cancer progression， and the GSDME level was significantly higher in GPL patients than in the normal group. Compared with the blank serum， WFC-containing serum lowered the level of NF-κB and inhibited the nuclear translocation of NF-κB （P<0.05）， and it inhibited pyroptosis by suppressing the cleavage of Caspase-3 on GSDME （P<0.05， P<0.01）. The analysis of patient specimens further demonstrated that WFC treatment down-regulated the NF-κB level and GSDME cleavage （P<0.01）， inhibited pyroptosis， and alleviated gastric mucosal inflammation and intestinal epithelial metaplasia. ConclusionPyroptosis is involved in the progression of gastric cancer， and WFC inhibits pyroptosis via the NF-κB/GSDME pathway， thereby alleviating gastric mucosal inflammation in GPL.

Objective To analyze the current situation, change trend and influencing factors of the delay in the treatment of tuberculosis patients in Xianning from 2008 to 2021, and to provide a scientific basis for controlling the tuberculosis epidemic. Methods The current situation and trend of the delay in the treatment of tuberculosis patients in Xianning City from 2008 to 2021 were described, and the multivariate Logistic regression analysis model was used to explore the influencing factors of the treatment delay in tuberculosis patients. Results The delay rate of seeking medical care for tuberculosis patients in Xianning from 2008 to 2021 was 58.53%, and the delay rate in the first six years tended to be stable. From 2014 to 2016, it increased slightly and then decreased year by year to 44.76% in 2021. Different gender and age groups showed the same trends as overall patients. The analysis results of the multivariate Logistic regression analysis model showed that females, household registration address in Jiayu County, occupations including service industries, workers, farmers and herdsmen, retirees, and others, the diagnosis result being positive for etiology, and the direct treatment in the patient source were high-risk factors for patients with delayed treatment. The risk of delay in treatment in ≥ 65-year-old patients was lower than that of < 25-year-old patients. Conclusion From 2008 to 2021, the phenomenon of delay in the treatment of patients with pulmonary tuberculosis in Xianning City is relatively common, and the high-risk factors of the delay in treatment need to be paid more attention to.

Background Dibutyl phthalate (DBP) is a common plasticizer in daily life and has been proved to be related to the exacerbation of allergic asthma. Domestic and foreign studies have shown that lipid peroxidation is closely related to the severity of asthma, which can be used as a basis for the diagnosis and treatment of asthma. Whether DBP can induce lipid peroxidation in allergic asthma remains to be further studied. Objective To investigate whether DBP aggravates allergic asthma by inducing lipid peroxidation in allergic asthma mice. Methods Eighty male BALB/c mice were randomly divided into 4 groups, namely control group, DBP group (40 mg·kg⁻¹), 50 μg ovalbumin (OVA) group (allergic asthma model group), and DBP+OVA group. The DBP group and the DBP+OVA group were given DBP by gavage from Day 1 to 28, and the OVA group and the DBP+OVA group were sensitized by intraperitoneal injection of OVA, once every 3 d, a total of 5 injections, from Day 9 to 21. From Day 29 to 35, the OVA group and the DBP+OVA group were challenged by OVA atomization. After the exposure, samples of blood and lung were collected. The airway hyperresponsiveness of mice was observed by lung function analysis. The serum contents of immunoglobulin E (IgE), OVA-specific immunoglobulin E (OVA-IgE), and lung homogenate levels of interleukin 4 (IL-4) were detected by enzyme-linked immunosorbent assay (ELISA) to evaluate airway allergic inflammation. The pathological changes of lung tissues were observed after hematoxylin-eosin (HE) staining and collagen fiber (Masson) staining. The contents of reactive oxygen species (ROS), lipid ROS, glutathione peroxidase 4 (GPX4), reduced glutathione (GSH), malondialdehyde (MDA), and 4-hydroxynonenal (4-HNE) in lung homogenates were detected by ELISA to evaluate lipid peroxidation. Results The results of lung function analysis showed that compared with the control group, the inspiratory resistance (Ri) and expiratory resistance (Re) of the OVA group and the DBP+OVA group were increased, and the lung compliance (Cldyn) was decreased. The DBP + OVA group was more severe, and the difference between the OVA group and the DBP + OVA group was statistically significant (P<0.05 or P<0.01). Compared with the control group, the contents of IgE, OVA-IgE, and IL-4 in the OVA group and the DBP+OVA group were increased (P<0.05 or P<0.01), which indicated more severe allergic airway inflammation. The HE sections of the OVA group and the DBP+OVA group showed inflammatory cell infiltration around the airway, airway wall hyperplasia and thickening, and severe airway deformation, and the presentation of the DBP+OVA group was the most serious. After Masson staining, the OVA group and the DBP+OVA group showed depositions of a large number of collagen fibers, and the blue collagen fibrosis in the DBP+OVA group was even more serious. ROS, lipid ROS, MDA, and 4-HNE levels increased and GSH and GPX4 levels decreased in the OVA and DBP+OVA groups (P<0.05 or P<0.01), with the most severe effect in the DBP+OVA group. Conclusion DBP may induce lipid peroxidation in mice allergic asthma by producing excessive ROS which may aggravate the allergic asthma in mice.

Aim To explore the effect of GSK-3β (glycogen synthase kinase-3 beta) inhibitor TDZD-8 on the neuropathic pain induced by side effects of chemotherapeutic drug oxaliplatin and the underlying mechanism. Methods The rat model of oxaliplatin-induced neuropathic pain was established by intraperitoneal injection of oxaliplatin for five consecutive days; the anti-nociception effect was detected by intrathecal injection of TDZD-8. The spontaneous flinches and mechanical pain threshold were used to detect the changes of pain behavior of rats; immunofluorescence and Western blot analysis were used to detect the changes of spinal inflammation and protein levels of rats. Results Intrathecally injection of TDZD-8 significantly alleviated oxaliplatin induced hyperalgesia in rats. TDZD-8 injection obviously inhibited the activation spinal microglia and the inflammatory reaction. TDZD-8 administration significantly inhibited GSK-3β activation. Conclusion TDZD-8 blocks GSK-3β activation, decreases NLRP3 (NOD-, LRR-, and pyrin domain-containing protein 3) inflammasome mediated spinal inflammation and alleviates neuropathic pain.

Objective To evaluate the effect of the current immunization strategy for hepatitis B virus (Hepatitis B) in blocking mother-to-infant transmission in Hubei Province, and to explore the mechanism and possible influencing factors of failure of mother-to-infant blockade. Methods A multi-stage random sampling method was used to select 2 counties or districts in Hubei Province. Through maternity hospital health handbook, neonatal health record or hospital medical record system, hepatitis B virus (HBV) surface antigen (HBsAg)-positive pregnant women in 2012-2018 years were included to retrospectively investigate their delivery status and the HBV infection status of their children. Results Among the 302 newborns, 32 were positive for HBsAg, and the success rate of blockade of mother-to-infant transmission of hepatitis B was 89.45%. Further analysis showed that 68.21% (206 / 302) of newborns were delivered in township hospitals, 66.23% (200 / 302) were delivered by caesarean section and 41.72% (126 / 302) were breastfed, while 16.89% (51/302) were positive for hepatitis B virus e antigen (HBeAg), and 41.06% (124/302) were positive for anti-HBe. The vaccination rate of hepatitis B immunoglobulin (HBIG) during pregnancy was 3.31% (10/302), and the newborn HBIG vaccination rate was 94.37% (285/302). There were 84.11% (254/302) of pregnant women taking protective measures in daily life. Logistic regression analysis showed that township hospitals (OR=2.82, P<0.05), HBeAg positivity during pregnancy (OR=8.68, P<0.05), and HBIG vaccination during pregnancy (OR=12.62 , P<0.05) were risk factors for failure of mother-to-infant blockade, while anti-HBe positivity during pregnancy (OR=0.22, P<0.05), vaccination of newborns with HBIG (OR=0.20, P<0.05), and protective measures taken in daily life (OR=0.28, P<0.05) were protective factors for mother-to-infant interruption. Conclusion Deliveries in township hospitals and HBeAg-positivity during pregnancy are more likely to fail in blocking of mother-to-infant transmission of hepatitis B. HBIG vaccination during pregnancy does not reduce the risk of blockade failure. Neonatal HBIG vaccination, anti-HBe positivity during pregnancy, and protective measures in daily life can reduce the risk of blockade failure of mother-to-infant transmission of hepatitis B.

Based on the dual needs of analgesia and anti-inflammation in trauma treatment, this study uses acetaminophen and moxifloxacin hydrochloride as active pharmaceutical ingredients and develops a composite bilayer tablet with a dual-phase drug release system by using binder jet 3D printing technology. Due to the complexity of the 3D printing process, there is an interaction between the various parameters. Through the optimization of the process, the relationship between the key process parameters can be determined more intuitively. In this study, the process of extended-release tablets was optimized to maintain the mechanical properties of the tablets while realizing the regulation of release. The full-factor experimental design of three central points 2³ was used to analyze the factors that significantly affect the quality attributes of extended-release tablets and the interaction between factors. The optimal extended-release process parameters were obtained by the response optimizer: the inkjet quantity of the printing ink was 10 (about 13.8 pL), the powder thickness was 180 μm, and the running speed was 360 mm·s^-1. The in vitro of release of 3D printed composite bilayer tablets showed that the in vitro of release of 3D printed tablets and commercially available tablets conformed to the Ritger-Peppas release model. The results of porosity showed that the immediate-release layer of the preparation has many pores and large pore size, and the dissolution of the immediate release layer within 15 min was greater than 85%. The internal pore size of the extended release layer is large, but it can still release slowly for up to 8 h, the mechanism may be related to the extended release of HPMC gelation. On the basis of verifying the rationality of the design goal of 3D printed composite bilayer tablets, this study also provides a theoretical basis for the preparation of 3D printing complex preparations.
