Objective:To investigate the comorbidity status of hypertension, diabetes, and dyslipidemia (the"three diseases") among residents aged≥40 in Liaoning Province, and to explore the correlation between the comorbidity and cardiovascular disease mortality.Methods:This investigation was a prospective cohort study. From February 2017 to March 2019, a multi-stage stratified cluster random sampling method was used to carry out a baseline survey of 18 758 permanent residents aged≥40 years in Liaoning Province. Demographic information and history of hypertension, diabetes, and dyslipidemia were collected and followed up every year. Death was mainly identified by linkage to the Population Death Information Registration Management System. Cox proportional hazard regression model was used to analyze the association between the comorbidity of the "three diseases" and cardiovascular disease mortality risk.Results:A total of 18 758 residents aged≥40 in Liaoning Province were included, with an age of (60.3±9.9) years and 7 325 males (39.1%). The comorbidity rate of hypertension, diabetes, and dyslipidemia was 6.7% (1 256/18 758), and the standardized prevalence rate was 5.4%. The comorbidity rate increased with age (P<0.001), which was higher in women than in men, and more significant in urban areas than in rural areas (all P<0.001). The comorbidity of "three diseases" accounted for 39.3% (1 256/3 198), 18.7% (1 256/6 710), and 11.8% (1 256/10 653) in patients with diabetes, dyslipidemia, and hypertension, respectively. With a follow-up of (4.3±0.6) years, 463 people died of cardiovascular disease. The mortality rate of cardiovascular disease in the comorbidity of hypertension, diabetes, and dyslipidemia was 8.74/1 000 person-years. After adjusting potential confounders, Cox proportional hazard regression model analysis showed that compared with normal individuals, the hazard ratio of cardiovascular disease mortality in patients with the "three diseases" was 2.55 (95% CI: 1.63-3.99). Conclusion:The prevalence of comorbidity of hypertension, diabetes, and dyslipidemia among residents aged≥40 in Liaoning Province was relatively high, and the risk of cardiovascular disease mortality in patients with the "three diseases" was increased.

Objective To investigate the differences in clinical characteristics among children on prolonged mechanical ventilation(PMV)due to different primary diseases.Methods A retrospective analysis was performed on the clinical data of 59 pediatric patients requiring PMV from July 2017 to September 2022.According to the primary disease,they were divided into respiratory disease(RD)group,central nervous system(CNS)group,neuromuscular disease(NMD)group,and other disease group.The four groups were compared in terms of general information,treatment,and outcome.Results There were significant differences among the four groups in age,body weight,Pediatric Logistic Organ Dysfunction-2(PELOD-2)score,Pediatric Risk of Mortality Ⅲ(PRISM Ⅲ)score,analgesic and sedative treatment,nutrition supply,rehabilitation treatment,tracheotomy,successful ventilator weaning,and outcomes(P＜0.05).Compared with the RD group,the CNS group and the other disease group had a significantly higher age and a significantly higher proportion of children receiving rehabilitation treatment,and the CNS group had a significantly higher proportion of children receiving tracheotomy(P＜0.008).Compared with the other disease group,the CNS group and the NMD group had significantly lower PELOD-2 and PRISM Ⅲ scores,and the CNS group had a significantly higher proportion of children with successful ventilator weaning and a significantly higher proportion of children who were improved and discharged(P＜0.008).Conclusions There are differences in clinical characteristics among children receiving PMV due to different etiologies.Most children in the RD group have a younger age,and children in the CNS group have a relatively good prognosis.

Objective To investigate the effect of varying ureteral wall thickness(UWT)at the site of ureteral stones on the clinical efficacy of ureteroscopic lithotripsy(URL).Methods The clinical data of 164 patients with ureteral stones in our hospital were retrospectively analyzed.According to different UWT,the patients were divided into the mild thickening group(84 cases,UWT<3.16 mm),the moderate thickening group(31 cases,UWT 3.16 to 3.49 mm),and the severe thickening group(49 cases,UWT>3.49 mm),and the differences of clinical related indicators among the three groups were compared.Results The incidence of postoperative renal colic and leukocyte disorder in the mild thickening group and the moderate thickening group were lower than those in the severe thickening group,and the differences were statistically significant(P<0.05).The postoperative catheterization time in the mild thickening group and the moderate thickening group were shorter than that in the severe thickening group,and the incidences of secondary lithotripsy,residual stones and stone return to kidney in the mild thickening group and the moderate thickening group were lower than those in the severe thickening group,with statistically significant differences(P<0.05).The length of hospital stay and hospitalization cost in the mild thickening group and the moderate thickening group were shorter/less than those in the severe thickening group,with statistically significant differences(P<0.05).Conclusion With the increase of UWT(especially when UWT>3.49 mm),the incidence of postoperative complications and hospitalization cost of URL increase to varying degrees,and the surgical efficacy decreases.In clinical work,UWT measurement holds potential value in predicting the surgical efficacy and complications of URL.

Oral health is closely related to systemic health. Common chronic oral diseases, periodontitis and periapical inflammation for example, not only affect the health of oral soft and hard tissues including the alveolar bone and gums, but may also cause changes in systemic conditions such as chronic low-grade inflammation, elevated oxidative stress levels, and dysbiosis of the microbiota. These changes in systemic health can exacerbate the progression of obesity. Therefore, through proactive oral health interventions such as maintaining good oral hygiene habits, modifying dietary structures, and undergoing oral examinations, it is possible to effectively prevent and alleviate inflammatory oral diseases, and actively intervene in obesity. This article delves into the impact of inflammatory oral diseases on obesity and their underlying mechanisms, defines the concept of "oral proactive healthcare", and systematically summarizes their preventive and therapeutic effects on inflammatory oral diseases, thereby demonstrating the potential of improving obesity through proactive oral health strategies.

Aim To investigate the analgesic effect of ginsenoside Rd(GSRd)on spared nerve injury(SNI)induced neuropathic pain(NP)in mice and the under-lying mechanism.Methods SNI model was estab-lished and behavioral indexes were tested to verify the stability of the model and the analgesic effect of GSRd on neuralgia induced by SNI.The relationship between SNI-induced neuralgia and GABaergic nerve was ana-lyzed by GSRd in combination with gamma-aminobutyr-ic acid(GABA)system tool.Immunofluorescence staining was used to observe ventrolateral preoptic nu-cleus(VLPO)and ventrolateral periaqueductal gray in rats with neuralgia induced by SNI.The expression of c-Fos,c-Fos and GAT-1 immunopositive cells in VL-PAG and SDH were analyzed.The relationship be-tween the analgesic effect of GSRd and the nuclear group and nuclear group neurons of pain transduction pathway was analyzed.Results The pain threshold of SNI neuralgia mice began to change on the 3rd day af-ter operation,and pain sensitivity was produced,which lasted for at least 14 days.GSRd 500 or 1000 mg·kg-1 increased the pain threshold of SNI-induced neu-ralgia mice.GABA system tool drug could coordinate or antagonize the therapeutic effect of GSRd on neural-gia induced by SNI in mice.The c-Fos immunopositive cells of VLPO,VLPAG and SDH revealed a notable in-crease in SNI mice,and GSRd 500 mg·kg-1could re-duce the number of c-Fos and GAT-1 co-expressing im-munopositive cells in VLPO,VLPAG and SDH mice in-duced by SNI.Conclusions The neuralgia model in-duced by SNI is stable,and GSRd has significant anal-gesic effect.The mechanism involves down-regulating GAT-1 in VLPO,VLPAG and SDH to reduce its re-uptake of GABA in the synaptic gap,thereby enhancing the inhibitory effect of central GABaergic nerve.

Objective:To evaluate the role of Toll-like receptor 4 (TLR4)/nuclear transcription factor κB (NF-κB) signaling pathway in long-term cognitive impairment induced by multiple exposures to sevoflurane anesthesia in neonatal rats.Methods:Seventy-five SPF healthy newborn Sprague-Dawley rats of either sex, aged 6 days, weighing 12-20 g, were divided into 3 groups ( n=25 each) using a random number table method: control group (group C), multiple exposures to sevoflurane anesthesia group (group S) and TLR4 inhibitor plus multiple exposures to sevoflurane anesthesia group (group I+ S). The rats in group S and group I inhaled 3% sevoflurane for 2 h at 6, 7 and 8 days after birth. TLR4 inhibitor TAK-242 10 mg/kg was intraperitoneally injected before each exposure to sevoflurane in group I, and the equal volume of normal saline was given instead in the other two groups. The spontaneous activity was evaluated by open field test on day 29 after birth, and the cognitive function was assessed by Morris water maze test on days 30-34 after birth. After the behavioral test, the blood samples from the abdominal aorta were collected, and then the rats were sacrificed under deep anesthesia to isolate the hippocampal tissues for measurement of the levels of S100β and neuron-specific enolase (NSE) in serum and hippocampal interleukin-1β (IL-1β), IL-6 and tumor necrosis factor α (TNF-α) (by enzyme-linked immunosorbent assay), expression of TLR4, NF-κB p65 and phosphorylated NF-κB p65 (p-NF-κB p65) (by Western blot) and for microscopic examination of the pathological changes of hippocampal CA1 region after HE staining. Results:Compared with group C, the escape latency was significantly prolonged, the number of crossing the original platform was reduced, the TLR4 expression was up-regulated, the ratio of p-NF-κB p65/NF-κB p65 was increased, the levels of serum S100β protein and NSE and hippocampal IL-1β, IL-6 and TNF-α were increased ( P<0.05), and the pathological changes in the hippocampal CA1 region were aggravated in group S. Compared with group S, the escape latency was significantly shortened, the number of crossing the original platform was increased, TLR4 expression was down-regulated, the ratio of p-NF-κB p65/NF-κB p65 was decreased, the levels of S100β and NSE in serum and hippocampal IL-1β, IL-6 and TNF-α were decreased ( P<0.05), and the pathological changes in hippocampal CA1 area were significantly attenuated in group P. Conclusions:The mechanism by which multiple exposures to sevoflurane anesthesia induces long-term cognitive impairment is related to activation of TLR4/NF-κB signaling pathway and increase in hippocampal inflammatory responses in neonatal rats.

Objective:To evaluate the role of nuclear factor E2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) signaling pathway in edaravone-induced attenuation of long-term cognitive impairment caused by long-time sedation with propofol in the neonatal rats.Methods:Eighty SPF healthy newborn Sprague-Dawley rats of both sexes, aged 7 days, weighing 15-20 g, were divided into 4 groups ( n=20 each) using a random number table method: control group (group C), propofol group (group P), edaravone+ propofol group (group EP) and Nrf2 inhibitor ML385+ edaravone+ propofol group (group MEP). Propofol 75 mg/kg was intraperitoneally injected once a day for 7 consecutive days in P group, EP group and MEP group, respectively, while the equal volume of medium/long chain fat emulsion injection was intraperitoneally injected in C group. Edaravone 3 mg/kg was intraperitoneally injected at 30 min before each propofol injection in EP and MEP groups, and ML385 15 mg/kg was intraperitoneally injected simultaneously in group MEP. The spontaneous activity was evaluated by the open field test on day 29 after birth, and the cognitive function was assessed by Morris water maze test on days 30-34 after birth. The rats were sacrificed after the end of water maze test, and brains were removed and hippocampal tissues were obtained for determination of reactive oxygen species (ROS) levels (by flow cytometry), superoxide dismutase (SOD) and malondialdehyde (MDA) levels (by enzyme-linked immunosorbent assay) and expression of Nrf2 and HO-1 (by Western blot) and for microscopic examination of the pathological changes in the hippocampal CA1 area (using HE staining). Results:There was no significant difference in the speed, distance and time of stay at the center of the open field among the four groups ( P>0.05). Compared with C group, the escape latency was significantly prolonged, the number of crossing the original platform quadrant was reduced, the levels of MDA and ROS were increased, the activity of SOD was decreased, the expression of Nrf2 and HO-1 was down-regulated ( P<0.05), and the pathological injury was observed in the hippocampal CA1 region in group P. Compared with P group, the escape latency was significantly shortened, the number of crossing the original platform quadrant was increased, the levels of MDA and ROS in the hippocampus were decreased, the activity of SOD was increased, the expression of Nrf2 and HO-1 was up-regulated ( P<0.05), and the pathological injury in the hippocampal CA1 region was significantly alleviated in EP group. Compared with EP group, the escape latency was significantly prolonged, the number of crossing the original platform quadrant was reduced, the levels of MDA and ROS were increased, the activity of SOD was decreased, the expression of Nrf2 and HO-1 was down-regulated ( P<0.05), and the pathological injury was aggravated in the hippocampal CA1 region in MEP group. Conclusions:The mechanism by which edaravone attenuates long-term cognitive impairment caused by long-time sedation with propofol is related to activation of Nrf2/HO-1 signaling pathway and inhibition of oxidative stress in the neonatal rats.

Polymer nanomaterials have been attracted more and more attention because of their advantages such as long circulation, reduced immunogenicity and less side effects, and have become a hot research topic in nanomaterials. However, the number of polymer nanomedicines successfully applied in clinical application is very limited, and the unsatisfactory pharmacokinetic behavior is one of the main reasons for thisresult. After polymer nanoparticles enter the body, they will release free drugs and polymer excipients. Polymer nanoparticles are the loaded drugs and free drugs are the active chemicals for efficacy, while polymer excipients may cause excipient drug interactions. Therefore, the focus of the pharmacokinetics study of polymer nanoparticles should not be only limited to the free drugs themselves, but should also focus on the loaded drugs, free drugs and polymer excipients. The dynamic changes of polymer excipients and their metabolites pose new requirements and challenges for the bioanalysis of polymer nanomedicines. The characteristics and application scope of common analytical methods for detection polymer nanomedicines including chromatographic assay will be discussed in this paper. Moreover, this review will also summarize the absorption, distribution, metabolism and excretion of polymer nanomedicines. We hope this review will provide reference for the pharmacokinetics study, safety and effectiveness evaluation of polymer nanomedicines.
