ABSTRACT

Objective To compare the accuracy of bedside lung ultrasound in emergency(BLUE)and combined cardiac-lung and additional ultrasound(CLAUS)for diagnosing the causes of acute dyspnea.Methods Totally 1 016 patients with acute dyspnea were retrospectively enrolled and divided into cardiogenic pulmonary edema group(n=268),pneumonia group(n=574),pneumothorax group(n=33),pulmonary embolism group(n=67)and CAD(chronic obstructive pulmonary disease/asthma/diaphragmatic dysfunction)group(n=74)according to the causes of acute dyspnea.The findings of CLAUS protocol were compared among groups,and the accuracy of BLUE and CLAUS protocol for diagnosing the causes of acute dyspnea were also compared.Results CLAUS showed that B-B and B-C were the most common modes in cardiogenic pulmonary edema group,while A-B/A-C/B-A/B-B/B-C/C-C modes were common in pneumonia group,and A-A mode was the most common in pneumothorax group,pulmonary embolism group and CAD group.Significant differences of the manifestations of pulmonary ultrasound,pleural feature of anterior chest wall,left/right cardiac insufficiency and abnormal inferior vena cava diameter were found among groups(all P<0.05).The accuracy of BLUE and CLAUS protocol for diagnosing the causes of acute dyspnea was 86.91%(883/1 016)and 94.49%(960/1 016),respectively,the latter was higher than the former(χ2=34.587,P<0.05).Conclusion CLAUS protocol could be used to effectively diagnose the causes of acute dyspnea,with higher accuracy than BLUE protocol.

ABSTRACT

Objective:To analyze the cardio-pulmonary ultrasound features of cardiogenic pulmonary edema (CPE) and pneumonia in adults with acute dyspnea, and to construct a differential diagnosis model.Methods:Seven hundred and forty-three patients with sudden acute dyspnea admitted to Hebei General Hospital from November 2018 to May 2022 were retropectively included. Ultrasonographer A performed lung ultrasound with 12 zone method, and interpreted and recorded the ultrasonic signs (including A-lines area, B-lines area, consolidation area and pleural effusion area) together with ultrasonographer B. According to the ultrasonic characteristics of the whole lung, it was divided into A-profile and B-profile. According to the continuity and symmetry of the distribution of B-lines in bilateral lung fields, it could be divided into bilateral lung continuous and discontinuous B-profile, bilateral lung symmetric and asymmetric B-profile. Left ventricular ejection fraction (LVEF), left ventricular filling pressure (E/e′), right ventricular dilatation, tricuspid annular systolic displacement (TAPSE) and inferior vena cava diameter (IVCD) were evaluated by echocardiography, and all the indexes were transformed into binary variables. According to the final clinical diagnosis and treatment results, the disease was divided into CPE group and pneumonia group. Binary Logistic regression model was used to screen independent influencing factors, and partial regression coefficient β value was used as a weight to assign a score, and a differential diagnosis model was established based on the total score. The predictive value of the model was evaluated by the receiver operating characteristic curve (ROC) and area under curve (AUC). After the model was built, 30 patients with CPE or pneumonia were independently collected by ultrasonographer C as external validation data, which were included in the model to draw ROC curve and evaluate the differential diagnosis efficiency of the model. The consistencies between ultrasonographer A and B, A and C in observing lung ultrasound were explored.Results:A total of 743 patients from 43 clinical departments were included, including 246 cases in CPE group and 497 cases in pneumonia group. Multivariate logistic regression analysis showed that bilateral lung continuous B-profile, bilateral lung symmetric B-profile, ≥1 pleural effusion area, LVEF<50%, E/e′>14 were the risk factors for CPE (all OR>1, P<0.05), and ≥1 consolidation area and ≥1 pleural sliding disappearance area were the protective factors for CPE (all OR>1, P<0.05). The sensitivity, specificity and AUC of combined cardio-pulmonary ultrasound index β value weight score in the differential diagnosis of CPE and pneumonia were 0.939, 0.956 and 0.986, respectively. The AUC of external validation data was 0.904. Ultrasonographer A and B, A and C had good consistency in the interpretation of lung ultrasound signs ( P<0.05). Conclusions:The differential diagnosis model based on combined cardio-pulmonary ultrasound indexes has high differential diagnosis efficiency for CPE and pneumonia, and can be used in bedside cardio-pulmonary ultrasound practice.

ABSTRACT

Objective:To explore the value of clinical pharmacists in the clinical treatment of a patient with Guillain Barré syn-drome through pharmaceutical care. Methods:Clinical pharmacists participated in the entire treatment process and gave rational sug-gestions about the selection,dosage and course of the drugs,such as glucocorticoid,immunoglobulin and antibiotics. Meanwhile,clini-cal pharmacists focused on the adverse drug reactions. Results:The patient′s condition was controlled and improved gradually. During the hospitalization,the patient developed skin rash and abnormal liver function,while the symptom was improved after the anti allergy and liver protection treatment,and no obvious effect on the primary disease was shown. Conclusion:Clinical pharmacists can help to optimize treatment regimen in order to ensure the safety and effectiveness of patients’medication.

ABSTRACT

Objective:To explore the value of clinical pharmacist in clinical treatment through the pharmaceutical care on a patient with Japanese B encephalitis complicated with pulmonary infection. Methods:Clinical pharmacist participated in the whole treatment process and gave suggestions on the selection,dosage and course of the drugs prescribed for anti-virus, anti-epilepsy and anti-infection by focusing on the drug interactions and adverse reactions. Results:The treatment course of the patient was smooth, and the pathoge-netic condition was brought under control gradually while no obvious adverse drug reactions occurred. Conclusion:The work of clinical pharmacist can help to optimize treatment programs to ensure the safety and effectiveness of medication.

ABSTRACT

AIM: To investigate the pharmacokinetic properties and bioequivalence of nifedipine sustained-release tablets after multiple doses administration in healthy volunteers. METHODS: Twenty two male healthy volunteers were enrolled in a randomized two-way crossover design with multiple doses (20 mg·d-1×7 d) study. Nitrendipine was used as the internal standard and the concentrations of nifedipine in plasma were determined by HPLC-APCI-MS. The pharmacokinetic parameters were calculated and the bioequivalence were compared by DAS (ver 1.0) program. RESULTS: The pharmacokinetic parameters of test and reference preparations were as follows: Cmax (52.5±27.4) and (54.0±31.2) ng·ml-1;Cmin (5.4±4.1) and (6.2±5.9) ng·ml-1;Cav (16.8±9.2) and (19.3±12.4) ng·ml-1;Tmax (3.7±0.9) and (4.1±1.1) h;t1/2 (8.9±4.9) and (8.5±3.1) h;AUC0-τ (403.4±221.0) and (461.9±296.6) μg·h·L-1, AUC0-36h (444.4±256.1) and (503.1±330.9) ng·h·ml-1;AUC0-∞ (482.1±268.9) and (542.3±348.4) ng·h·ml-1;DF (299.8±117.7)% and (279.2±97.5)%, respectively. There were no significant differences (P>0.05) in Tmax, Cmax, Cmin, Cav, DF, AUC0-τ, AUC0-36h, AUC0-∞ and t1/2 between the two preparations. The relative bioavailability of test tablets was (100.6±38.6)%. CONCLUSION:The test and reference preparations were bioequivalence.

ABSTRACT

Objective: To observe the protective effect of Silybin Capsules (SC) on mice hepatic toxic injury induced by isonicotinic acid hydrazide (INH) and rifampin (RFP) when used in combination Methods: The serum level of ALT, liver index, contents of glutathion (GSH) and malondialdehyde (MDA), activity of microsomal cytochrome P450 and its isoform P4502E1 in liver were measured. Results: SC obviously inhibited the rising of liver index, serum ALT, liver MDA and the activity of microsomal cytochrom P450 and its isoform P4502E1, and increased the liver GSH. Histopathological examination showed that Silibinin Capsules evidently alleviated the condition of the degeneration of hepatic cells and that of necrosis. Conclusion: The protective effect of SC on mice hepatic injury induced by both IIVit and RFP may be related to stabilizing the liver membrane, inhibiting the the lipid peroxidation, scavenging the free radical and decreasing the activity drug metabolizing enzyme.
