Objective To investigate the pharmacokinetics ( PK ) and pharmacodynamics ( PD ) processes of rabeprazole in inhibiting gastric acid secretion with the combined PK-PD model. Methods A total of 10 healthy volunteers were given a intravenous infusion of 20 mg rabeprazole over a 30-min period. The concentration of rabeprazole in the plasma at different time points was detected by HPLC,and the PK parameters were calculated by DAS 2. 0 software. At the same time the intragastric pH was monitored over 24 hours to fit the PD parameters with indirect inhibition model. Results The main PK parameters,t1/2,Cmax,and AUC were(60. 5±17. 3)min,(1 299. 1±201. 0)ng·mL-1,and(106. 4±26. 0)mg·min·L-1, respectively.The corresponding PD parameters,Kin,Ke,IC50 and Imax were(8.200±3.362)h-1,(1.080±0.378)h-1,(0.286± 0. 129)mg·L-1 and(6. 93± 2. 15)pH,respectively. Conclusion The PK of rabeprazole in healthy volunteers conforms to one compartment model,and the PD fits the indirect response inhibition model. The equation can effectively establish the relationship between the blood drug concentration and the effect.

Objective:To study and analyze the application effect of intervention plan based on unplanned readmission risk model (LACE) in the rehabilitation of patients with acute myocardial infarction (AMI) complicated with cardiac shock (CS) after percutaneous coronary intervention (PCI).Methods:Ninety-three patients with AMI complicated with CS who received PCI in Tianjin Union Medical Center from January 2019 to December 2020 were enrolled. The patients were divided into LACE intervention group ( n = 46) and routine intervention group ( n = 47) according to the different nursing intervention methods. The patients in the routine intervention group received routine interventions, including drug care, diet care, psychological care, health education and telephone follow-up, while those in the LACE intervention group were assessed for the risk of LACE, and then intervention measures were formulated according to the score of LACE index, including strengthening risk awareness, life behavior, daily life ability, self-care ability, health recovery and health needs. The follow-up period in both groups was 3 months. The changes of cardiac function, incidence of adverse cardiac events, readmission rate, self-management ability after intervention and quality of life level before and after intervention were compared between the two groups. Results:There was no significant difference in cardiac function or quality of life before intervention between the two groups. After intervention for 3 months, the cardiac function and quality of life in the two groups were improved as compared with those before intervention. The left ventricular ejection fraction (LVEF) in the LACE intervention group was significantly higher than that in the routine intervention group (0.533±0.076 vs. 0.492±0.072, P < 0.05), the left ventricular end diastolic diameter (LVEDD) was significantly lower than that in the routine intervention group (mm: 47.09±7.01 vs. 53.23±7.15, P < 0.01), and the World Health Organization Quality of Life-brief (WHOQOL-BREF) score was also significantly higher than that in the routine intervention group (66.32±6.19 vs. 55.79±7.26, P < 0.01). The scores of self-management ability in the coronary heart disease self-management scale (CSMS) after intervention in the LACE intervention group were significantly higher than those in the routine intervention group (adverse hobbies score: 17.37±3.24 vs. 14.21±2.73, symptoms score: 14.82±3.11 vs. 10.56±2.65, emotional cognition score: 16.17±2.83 vs. 12.95±2.41, first aid score: 11.85±1.94 vs. 10.62±1.56, disease knowledge score: 15.58±2.73 vs. 12.68±2.61, daily life score: 17.80±2.61 vs. 14.33±2.36, treatment compliance score: 11.47±1.84 vs. 8.56±1.23, all P < 0.01). The incidence of adverse cardiac events and readmission rate in the LACE intervention group were significantly lower than those in the routine intervention group (10.87% vs. 29.79%, 4.35% vs. 17.02%, both P < 0.05). Conclusion:The intervention plan based on LACE risk model can effectively promote postoperative rehabilitation of patients with AMI complicated with CS after PCI, and also help to improve patients' self-management ability and quality of life, which is worthy of clinical promotion and application.

Objective To provide theoretical and experimental proof for selecting and implying Tourette's syndrome(TS) animal models, validities of four TS models induced by chemical factors were compared. Methods Four TS models,namely AMP model,APO model,DO1 model and IDPN model were built up by using different chemical modeling agents. Through detecting spontaneous movement, climbing time and monoamine transmitters levels in striatum, four TS animal models were compared and evaluated from three levels of validities-face, prediction,construct. Results Compared with control group, spontaneous movement times raised ( t = 4. 746, P =0. 000) and level of DOPAC ( (0.99 ± 0. 177 ) ng/mg) in striatum increased (P = 0.029 ), and level of NE in striatum decreased in AMP model group( (0.11 ± 0.033 )ng/mg, P = 0.012). Compared with control group, climbing time prolonged (P = 0. 004) and levels of DA ( ( 10. 19 ± 1.23 ) ng/mg), 5-HT ( ( 0. 54 ± 0.08 ) ng/mg) in striatum raised(P=0. 019, P=0. 002),at the same time ,levels of DOPAC( (0.63 ±0.11 )ng/mg),HVA ((0.45 ±0.04 ) ng/mg) in striatum reduced (P < 0.01 ) in APO model group; Compared with control group, levels of DA ( ( 13.66 ± 1.55 ) ng/mg), DOPAC( (0.80 ±0. 11 ) ng/mg), HVA( ( 1.04 ± 0.14) ng/mg) grew downwards in striatum of DOI model mice(P=0.029,P=0.001, P= 0.004). Compared with control group, level of 5-HT in striatum increased in IDPN300 group ( (0.77 ± 0.09) ng/mg, P = 0.031 ). ConclusionFace validity of AMP model is temporal and that of IDPN model is steady and persistent. AMP model,APO model and DOI model possess predictive validity. AMP model,APO model,DOI model and IDPN model have potentiality of becoming construct validity model.

Qi arrival is the meridian qi response to acupuncture stimulation. Through analyzing the relevant concepts of qi arrival and summarizing the general understanding of it in clinic and on the basis of the collection of the relevant literature at home and abroad on the determination of qi arrival and its strength, the characteristics are analyzed on the present method and the method for the determination of qi arrival and its strength is discussed in terms of the results in the needling sensation scale. It is believed that the needling sensation and its strength can be used to determine whether the qi is arrived or not and its strength. The components of different types of needling sensation are much better applicable for the analysis on the characteristics and rules on the influence on qi arrival. This method is in compliance not only with the theoretic connotation of qi arrival, but also with the clinical general understanding, which lays the foundation for the analysis on the scale results.

OBJECTIVE:
To investigate relationship between anti-endothelial cell antibody(AECA) and response to dexamethasone in sudden hearing loss(SHL).
METHOD:
Forty-eight SHL patients and thirty normal controls with SHL were recruited in present study. AECA was detected by ELISA in serum of all normal controls and SHL patients as well as pure-tone average was examined by electronic audiometry during treatment in SHL patients. Both AECA-positive and -negative subjects received 10 mg/d venous dexamethasone for 5 days followed by gradual tapering of dose of 5 mg/d for another 5-day. Then pure-tone average was reexamined. Differences in hearing recovery between AECA-positive and -negative subjects and relationship between AECA level and hearing recovery were analyzed.
RESULT:
The prevalence of AECA detection was 68.75% (33 of 48 patients) in SHL patients, with significant difference compared with control subjects with 23.33% (7 of 30 controls) (P<0.01). After treatment, rates of response to dexamethasone in AECA-positive and -negative SHL patients were 81.8% (27 of 33 patients) and 33.3% (5 of 15 patients), respectively. Meanwhile, there was a significant difference in cure, excellent recovery, partly recovery and invalid between AECA-positive and -negative groups [21.2% (7/33), 33.3% (11/33), 27.3% (9/33) and 18.2% (6/33) versus 0, 13.3% (2/15), 20.0% (3/15) and 66.7% (10/15), P<0.01]. Except 5 subjects with AECA level more than 263 microg/L, hearing recovery was correlated to pretreatment AECA level (r=0.8084, P<0.01).
CONCLUSION
In sudden HL patients treated with dexamethasone, AECA might represent a serological marker of prognosis.

Objective:To explore the prognostic predictive value of deep neural network (DNN) assisted myocardial contrast echocardiography (MCE) quantitative analysis of ST-elevated myocardial infarction (STEMI) patients after successful percutaneous coronary intervention(PCI).Methods:A retrospective analysis was performed in 97 STEMI patients with thrombolysis in myocardial infarction-3 flow in infarct vessel after primary PCI in Renmin Hospital of Wuhan University from June to November 2021. MCE was performed within 48 h after PCI. Patients were followed up to 120 days. The adverse events were defined as cardiac death, hospitalization for congestive heart failure, reinfarction, stroke and recurrent angina. The framework consisted of the U-net and hierarchical convolutional LSTMs. The plateau myocardial contrast intensity (A), micro-bubble rate constant (β), and microvascular blood flow (MBF) for all myocardial segments were obtained by the framework, and then underwent variability analysis. Patients were divided into low MBF group and high MBF group based on MBF values, the baseline characteristics and adverse events were compared between the two groups. Other variables included biomarkers, ventricular wall motion analysis, MCE qualitative analysis, and left ventricular ejection fraction. The relationship between various variables and prognosis was investigated using Cox regression analysis. The ROC curve was plotted to evaluate the diagnostic efficacy of the models, and the diagnostic efficacy of the models was compared using the integrated discrimination improvement index (IDI).Results:The time-cost for processing all 3 810 frames from 97 patients was 377 s. 92.89% and 7.11% of the frames were evaluated by an experienced echocardiographer as "good segmentation" and "correction needed". The correlation coefficients of A, β, and MBF ranged from 0.97 to 0.99 for intra-observer and inter-observer variability. During follow-up, 20 patients met the adverse events. Multivariate Cox regression analysis showed that for each increase of 1 IU/s in MBF of the infarct-related artery territory, the risk of adverse events decreased by 6% ( HR 0.94, 95% CI =0.91-0.98). There was a 4.5-fold increased risk of adverse events in the low MBF group ( HR 5.50, 95% CI=1.55-19.49). After incorporating DNN-assisted MCE quantitative analysis into qualitative analysis, the IDI for prognostic prediction was 15% (AUC 0.86, sensitivity 0.78, specificity 0.73). Conclusions:MBF of the area supplied by infarct-related artery after STEMI-PCI is an independent protective factor for short-term prognosis. The DNN-assisted MCE quantitative analysis is an objective, efficient, and reproducible method to evaluate microvascular perfusion. Assessment of culprit-MBF after PCI in STEMI patients adds independent short-term prognostic information over qualitative analysis.It has the potential to be a valuable tool for risk stratification and clinical follow-up.
