OBJECTIVE:To provide reference for rational use of respiratory inhalants. METHODS:The utilization of respiratory inhalants in 34 hospitals from Nanjing area during 2012-2014 was analyzed by SPSS13.0 software in respects of DDDs,consumption sum,DDC,health insurance and self-paying cost and so on. RESULTS:Respiratory inhalants involved 4 kinds of drugs, 5 kinds of dosage forms,12 kinds of general name and 38 kinds of trade name(specification)in 34 hospitals from Nanjing area during 2012-2014. The total DDDs and total consumption sum of respiratory inhalants increased from 10 827.46×103 and 71,006, 500 yuan in 2012 and 14 627.25×103 and 99,137,100 yuan in 2014,there was no statistical significance(P>0.05). 4 categories of respiratory inhalants in the list of DDDs were anticholinergic agents,compound preparations,glucocorticoid and β2 receptor agonists; DDDs of each type increased year by year,but only that of anticholinergic agents had statistical significance(P<0.01). Consumption sum were glucocorticoid,compound preparations,anticholinergic agents and β 2 receptor agonists;consumption sum of each type increased year by year,but there was no statistical significance(P>0.05). 5 kinds of inhalants in the list of DDDs were aerosol preparation,power aerosols,atomizing solution,nasal spray and clickhaler. DDDs of aerosol preparation and power aerosols increased year by year,with statistical significance(P<0.05). Top one in the list of consumption sum was power aerosols during 2012-2013 and atomizing solution in 2014;power aerosols took up the first place in the list of total consumption in 3 years. Among 12 kinds of general name inhalants,top 4 inhalants in the list of DDDs were ipratropium bromide,salmeterol and fluticasone, albuterol and budesonide,and the constituent ratio of their total DDDs in 3 years were 40.16% ,16.71% ,13.51% and 13.39%,respectively;the sum of constituent ratio of total DDDs in 3 years was more than 80%. Top 3 inhalants in the list of consumption sum were budesonide,salmeterol and fluticasone, budesonide and formoterol,and the sum of constituent ratio of their total consumption sum in 3 years were 39.59%,20.81% and 12.50% ,respectively;the sum of constituent ratio was more than 70% . DDC of salbutamol was the lowest. Among 38 kinds of trade name(specification)inhalants,the type and cost of health insurance accounted for 92.11% and 95.02% .Pulmicort atomization suspension and Symbicort Turbuhaler(160 μg)took up the first place in the list of health insurance cost and self-paying cost respectively,and they were B directory of health insurance. CONCLUSIONS:The utilization of respiratory inhalants was basically reasonable in 34 hospitals from Nanjing during 2012-2014.

Using ALK5 inhibitor LY-3200882 as a lead compound, ten structurally novel compounds were designed by bioisosterism, conformational restriction and molecular docking technology. All structures were synthesized and confirmed by 1H NMR and HR-MS. The results of in vitro activity screening showed that most compounds had good kinase inhibitory activity. Among them, compound B4 showed significantly better ALK5 inhibitory activity than LY-3200882 (IC50 = 1.4 nmol/L vs 41.1 nmol/L), and had good inhibitory activity against TGFβ-ALK5-SMAD2/3 signaling pathway in NIH3T3 cells (IC50 = 14.2 nmol/L). Besides, compound B4 had good pharmacokinetic properties, such as oral exposure and bioavailability, which is worthy of further development.

Objective:To establish an early clinical prediction model for patients with chronic liver disease who are coinfected with hepatitis E virus (HEV), and quickly evaluate the probability of severe hepatitis in patients.Methods:A retrospective analysis was conducted on 87 patients with chronic liver diseases who were hospitalized at the Third Affiliated Hospital of Sun Yat-sen University from May 2018 to September 2023. Clinical features and laboratory indexes were analyszed and patients were classified to severe (TBIL >171 μmol/L with PTA <40%) and non-severe (TBIL <171 μmol/L with PTA >40%) groups. and Independent factors identified using LASSO regression were incorporated into a novel nomogram to identify patients at high risk of severe hepatitis in the early stages. The performance of the nomogram was evaluated using the area under the curve and the mean absolute error of the calibration curve.Results:Significant difference was observed in the serum total bile acid (TBA) level between the severe group [240.00 (183.30, 268.70) umol/L] and the non-severe group [93.40 (20.10, 271.70) μmol/L, U=269.00, P=0.002]. Additionally, the levels of apolipoprotein A1 (APOA1) [0.32 (0.18, 0.48) g/L] and uric acid (UA) [156.15 (117.00, 202.00) μmol/L] were significantly lower in the severe group compared to the non-severe group (APOA1: [0.77 (0.63, 1.06) g/L, U=71.00, P<0.001]; UA: [334.05 (243.70, 401.00) μmol/L, U=83.00, P<0.001]). The researchers developed a nomogram, which incorporated two independent factors (APOA1 and UA) and an additional variable (TBA), exhibiting a strong predictive ability, with an area under the curve (AUC) of 0.963 (95% confidence interval: 0.927-0.998) and a well-fitted calibration curve. Positive and negative predictive values of 94.0% and 88.2% were calculated, and a nomogram score of 129 or greater was considered indicative of a higher likelihood of developing severe illness. Conclusions:This nomogram offers a rapid and accurate means of evaluating the probability of severe illness in patients with chronic liver disease after overlapping infection with HEV, which can accurately and effectively predict the risk of severe illness in patients.

OBJECTIVE:
To establish a comprehensive evaluation system for the development of health services, and to assess the levels of health services in 2008 and 2009 in Hunan compared with seven other provinces in central China, so as to provide a basis for hygiene management decisions.
METHODS:
In order to establish a comprehensive evaluation system, a Delphi method, a boundary value method, and an RSR method were applied, respectively, to survey indices of health service development, to screen indices, and to determine index weights. A weighted TOPSIS method was used to evaluate the development status of health services of the eight provinces.
RESULTS:
The Cronbach's alpha coefficient of the questionnaire was 0.884, indicating a proper surface validity and a content validity. The expert positive coefficient, authority coefficient and Kendall coefficient were 93.75%, 0.8117, and 0.31, respectively. A comprehensive evaluation system, which consisted of 3 primary indices, 10 secondary indices and 52 tertiary indices, was established. The result of the comprehensive evaluation showed that the health services development of Hunan Province ranked 7th and 6th among the 8 central provinces for 2008 and 2009, respectively.
CONCLUSION
The established, comprehensive evaluation system has a high reliability. Health services development of Hunan Province is relatively backward among the 8 central provinces.

Objective:To investigate the clinical characteristics of acute ischemic stroke with anterior circulation large vessel occlusion caused by cardioembolism (CE) and large artery atherosclerosis (LAA) and the efficacy of endovascular treatment.Methods:Patients with acute ischemic stroke caused by large vessel occlusion in anterior circulation and received endovascular treatment in the Stroke Center of the 971 st Hospital of the PLA Navy from April 2014 to April 2021 were retrospectively enrolled. The etiological classification of stroke was CE or LAA. According to the modified Rankin Scale score at 90 d after onset, the patients were divided into good outcome group (0-2) and poor outcome group (>2). The demographic and clinical data between the groups were compared. Multivariate logistic regression analysis was used to determine the independent influencing factors of clinical outcome. Results:A total of 106 patients were enrollded. Their age was 61.39±13.73 years and 70 (66.0%) were males. Seventy-four patients (69.8%) were in the CE group and 32 (30.2%) were in the LAA group. Sixty-six patients (62.3%) had good outcomes. Univariate analysis showed that there were significant differences in gender, age, smoking, systolic blood pressure, diastolic blood pressure, baseline National Institutes of Health Stroke Scale (NIHSS) score, time from onset to femoral artery puncture, time from puncture to vascular recanalization, and the number of retrieval attempts between the CE group and the LAA group (all P<0.05), and there were no significant differences in the incidences of poor outcome, hemorrhagic transformation, and symptomatic intracranial hemorrhage. There were significant differences in systolic blood pressure, diastolic blood pressure, baseline NIHSS score, time from onset to femoral artery puncture, and blood perfusion grade after treatment between the good outcome group and the poor outcome group (all P<0.05). Multivariable logistic regression analysis showed that higher systolic blood pressure (odds ratio [ OR] 1.046, 95% confidence interval [ CI] 1.014-1.078; P=0.004), higher baseline NIHSS score ( OR 1.117, 95% CI 1.037-1.203; P=0.003), longer time from onset to femoral artery puncture ( OR 1.008, 95% CI 1.001-1.015; P=0.019) and poor blood perfusion after treatment ( OR 8.042, 95% CI 1.532-42.215; P=0.014) were significantly and independently associated with the poor outcomes. Conclusions:Compared with LAA, CE do not increase the risks of hemorrhagic transformation and symptomatic intracranial hemorrhage. The safety and efficacy of the two are similar.

Blood-brain barrier (BBB) damage after ischemia significantly influences stroke outcome. Compound LFHP-1c was previously discovered with neuroprotective role in stroke model, but its mechanism of action on protection of BBB disruption after stroke remains unknown. Here, we show that LFHP-1c, as a direct PGAM5 inhibitor, prevented BBB disruption after transient middle cerebral artery occlusion (tMCAO) in rats. Mechanistically, LFHP-1c binding with endothelial PGAM5 not only inhibited the PGAM5 phosphatase activity, but also reduced the interaction of PGAM5 with NRF2, which facilitated nuclear translocation of NRF2 to prevent BBB disruption from ischemia. Furthermore, LFHP-1c administration by targeting PGAM5 shows a trend toward reduced infarct volume, brain edema and neurological deficits in nonhuman primate
