Objective:To evaluate the incidence and case fatality rate of cardiovascular disease (CVD) among populations in urban and rural communities in eastern, central and western regions of China.Methods:The present study was based on the data of the Prospective Urban and Rural Epidemiology (PURE)-China cohort, which enrolled participants who had at least one follow-up visit and complete information on age and sex. Information on baseline demographics, cardiovascular risk factors, and prevention and treatment for CVD were collected. CVD and mortality events were documented using the standardized case report form of the PURE Global Study to assess the incidence and case fatality rate of CVD among populations in urban and rural communities in eastern, central and western China.Results:This study included a total of 47 262 community-dwelling participants (age: (51.1±9.6) years; female, n=27 529, 58.2%) from 115 urban and rural communities in 12 provinces across the eastern, central, and western regions of China. Over a follow-up period of 11.9 (9.5, 12.6) years, 2 686 deaths and 5 873 cardiovascular events were documented. The incidence of CVD was 11.90 (95%CI: 11.60-12.21)/1 000 person-years. A significant difference in CVD incidence was observed across regions ( Ptrend<0.001), which was highest in the western provinces (13.99 (95% CI: 13.33-14.65)/1 000 person-years), intermediate in the eastern provinces (11.92 (95% CI: 11.52-12.33)/1 000 person-years), and lowest in the central provinces (8.87 (95% CI: 8.25-9.50)/1 000 person-years). The 1-year case fatality rate of CVD demonstrated an increasing trend from eastern to western regions (eastern: 10.20% (95% CI: 6.95-14.73); central: 13.50% (95% CI: 9.90-18.14); western: 18.62% (95% CI: 14.95-22.94); Ptrend<0.001). Moreover, the incidence of major CVD was consistently higher in rural areas compared with urban areas across eastern ( P<0.001), central ( P=0.01) and western ( P<0.001)_regions, respectively. The 1-year case fatality rate in rural areas was also significantly higher compared with that in urban areas in both eastern ( P<0.001) and western regions ( P=0.02). Conclusions:The incidence and case fatality rate of CVD were high among middle-aged population in China, especially those in western regions with low socioeconomic levels and in rural areas.

Inhalation of crystalline silicon dioxide particles can induce silicosis, and the development of silicosis is closely related to the occurrence and development of pulmonary inflammation and pulmonary fibrosis. NOD-like receptor thermal protein domain associated protein 3 (NLRP3) inflammasome has been established as a major proinflammatory receptor for sensing environmental danger signals. Activation of NLRP3 inflammasomes after phagocytosis of silicon dioxide particles by pulmonary macrophages may be an important mechanism to induce oxidative stress and sustained inflammatory response in the lung. This article summarizes the role of NLRP3 inflammasome in the inflammatory response and pulmonary fibrosis in silicosis, and analyzes it as a potential target for silicosis treatment.

Objective To analyze the medication rules of traditional Chinese medicine (TCM) for patients with qi stagnation and blood stasis syndrome in the orthopedic department of Dongfang Hospital of Beijing University of Chinese Medicine. Methods The data of TCM internal prescriptions for patients with qi stagnation and blood stasis syndrome in the orthopedic department of Dongfang Hospital from 2019 to 2022 were analyzed using Excel software. The times of usage, frequency, and dosage of prescribed drugs, along with the medicinal properties, meridian tropism, and functional classification of the top 30 herbs were calculated. The association rules in SQL server 2008 R2 software were used for data mining to analyze the compatibility patterns and core medications in TCM prescriptions for orthopedic patients with qi stagnation and blood stasis syndrome. Results Among the orthopedic TCM prescriptions, the top five herbs with the highest usage frequency were Fuling, Danggui, Baishao, Zexie, Chuanxiong; the top 30 frequently used herbs were mainly sweet, warm, bitter, and pungent flavors; their meridian tropism was primarily the liver, spleen, and kidney meridians; and their primary functions were to activate blood circulation and dispel blood stasis, tonify deficiency, and promote diuresis and eliminate dampness. The medicinal properties, functions, and core medications of TCM prescriptions were in line with the principle of treating both the symptoms and the root causes of orthopedic diseases with qi stagnation and blood stasis syndrome. There were serious issues of overdosage in uthe se of prepared Baifuzi, Banxia(different processed products), and Shuizhi. Conclusion The analysis of medication patterns of TCM for orthopedic diseases through data mining methods can clarify the characteristics of medication use and identify issues of clinical overdosage, providing a basis for rational and safe clinical medication.

Objective:To understand the vancomycin dose, therapeutic drug monitoring(TDM) situation and therapeutic effect of children after liver transplantation.Methods:A retrospective analysis of the data of 98 children who received intravenous vancomycin treatment after liver transplantation were conducted in the Department of Critical Care Medicine of Beijing Friendship Hospital from January 2017 to June 2019, including demographic data, vancomycin dose, serum trough concentration, drug-related adverse reactions and clinical outcome data.Results:A total of 98 children received intravenous vancomycin treatment and at least one steady-state TDM blood sample was collected.Among them, 53 cases (54.1%) were male, and the median age was 9 months(5 months to 14 years old). The median first daily dose of vancomycin treatment was 50(30-60)mg/(kg·d), and the median duration of treatment was 14(3-54)days.Only 27.5%(27/98)of the children′s initial trough concentration reached the target concentration (10-20 mg/L), while 26 cases(26.5%) did not reach the target after adjusting the treatment.Six children(6.1%)had renal toxicity caused by vancomycin, and two children had skin rash.The effective treatment rate accounted for 51.7%(15/29). The initial trough concentrations of vancomycin in the effective and ineffective groups were(5.92±3.82)mg/L and(10.43±5.37)mg/L, respectively.The difference was statistically significant ( P=0.041). Conclusion:The rate of intravenous vancomycin in children after liver transplantation is low, and the dose needs to be adjusted individually.

OBJECTIVE: To investigate the effects of etomidate on electrophysiological properties and nicotinic acetylcholine receptors (nAChRs) of ventral horn neurons in the spinal cord. METHODS: The spinal cord containing lumbosacral enlargement was isolated from 19 neonatal SD rats aged 7-12 days. The spinal cord were sliced and digested with papain (0.18 g/30 mL artificial cerebrospinal fluid) and incubated for 40 min. At the ventral horn, acute mechanical separation of neurons was performed with fire-polished Pasteur pipettes, and perforated patch-clamp recordings combined with pharmacological methods were employed on the adherent healthy neurons. In current-clamp mode, the spontaneous action potential (AP) of the ventral horn neurons in the spinal cord was recorded. The effects of pretreatment with different concentrations of etomidate on AP recorded in the ventral horn neurons were examined. In the voltage-clamp mode, nicotine was applied to induce inward currents in the ventral horn neurons, and the effect of pretreatment with etomidate on the inward currents induced by nicotine were examined with different etomidate concentrations, different holding potentials and different use time. RESULTS: The isolated ventral horn neurons were in good condition with large diverse somata and intact processes. The isolated spinal ventral horn neurons (=21) had spontaneous action potentials, and were continuously perfused for 2 min with 0.3, 3.0 and 30.0 μmol/L etomidate. Compared with those before administration, the AP amplitude, spike potential amplitude and overshoot were concentration-dependently suppressed ( < 0.01), and spontaneous discharge frequency was obviously reduced ( < 0.01, =12). The APs of the other 9 neurons were completely abolished by etomidate at 3.0 or 30 μmol/L. At the same holding potential (VH=-70 mV), pretreatment with 0.3, 3.0 or 30.0 μmol/L etomidate for 2 min concentration-dependently suppressed the current amplitude induced by 0.4 mmol/L nicotine ( < 0.01, =7). At the holding potentials of - 30, - 50, and - 70 mV, pretreatment with 30.0 μmol/L etomidate for 2 min voltage-dependently suppressed the current amplitude induced by 0.4 mmol/L nicotine ( < 0.01, =6 for each holding potential). During the 6 min of 30.0 μmol/L etomidate pretreatment, the clamped cells were exposed to 0.4 mmol/L nicotine for 4 times at 0, 2, 4, and 6 min (each exposure time was 2 s), and the nicotinic current amplitude decreased gradually as the number of exposures increased. But at the same concentration, two nicotine exposures (one at the beginning and the other at the end of the 6 min pretreatment) resulted in a significantly lower inhibition rate compared with 4 nicotine exposures ( < 0.01, =6). CONCLUSIONS etomidate reduces the excitability of the spinal ventral neurons in a concentration-dependent manner and suppresses the function of nAChR in a concentration-, voltage-, and use-dependent manner.
