Objective To study serum levels of interleukin-4,10,interferon-g amma,tumor necrosis factor alpha and soluble interleukin-2 receptor in patients with pemphigus, and their correlation with disease severity. Methods Serum leve ls of different cytokines were determined by double antibody sandwich enzyme-li nked immunosorbent assay in 31 patients with pemphigus in acute and remission st ages, and in 15 normal controls. Serum autoantibody titer was determined by indi rect immunofluorescent assay (IIF). The severity of disease was recorded by the Rule of Nine for the calculation of burn surface area. Results IL-10 level was lower in the sera of patients in their acute stage than that of controls(P0.05). Conclusion There are abnormalities of serum levels of cytokine s in patients with pemphigus. Serum levels of IL-10, sIL-2R and IFN-?are cor related with the severity of the disease.

Objective:To explore the effect of enhanced recovery after surgery(ERAS)-based multidisciplinary collaboration model on shortening the time of forbidden eating before receiving surgery, provide the basis for the selection of the preoperative diet prohibition scheme.Methods:From January 2017 to February 2019, a total of 384 patients who received the operation in Qingdao Municipal Hospital were analyzed retrospectively. The patients who under the traditional preoperative diet prohibition scheme were taken as the control group(156 cases) while those who under the multidisciplinary cooperation mode nursing under the concept of eras were taken as the experimental group(228 cases). The experimental group formulated the perioperative diet prohibition process according to the guidelines of eras, and the experimental group carried out the perioperative diet management for the patients according to the procedure. The difference between the two groups in the time of fasting, hunger, thirst incidence, insulin resistance, temporary stop will be observed and compared.Results:The time of fasting was (4.01±1.55) h in the experimental group and (10.12±1.57) h in the control group,there was significant difference between the two groups( t value was -1.65, P < 0.01). The incidences of thirst,hunger were 13.2%(30/228), 11.8%(27/228) in the experimental group and 89.7%(140/156), 87.2%(136/156) in the control group, there were significant differences between the two groups(χ 2 values were 220.20, 215.20, P < 0.01). The levels of insulin resistance on the first and third day after operation were 1.85 ± 0.43,1.52±0.61 in the experimental group and 1.99±0.51, 1.67±0.49 in the control group, the differences were statistically significant ( t values were -2.90, -2.56, P < 0.05).The temporary stop rate was 1.75%(4/228) in the experimental group and 7.69%(12/156) in the control group, the difference was statistically significant( χ2 value was 8.19, P<0.01). Conclusions:The ERAS-based multidisciplinary collaboration model can effectively shorten the preoperative fasting time, reduce the level of insulin resistance, reduce the incidence of hunger and thirst, and improve the rate of temporary stop and adjustment.

Objective To explore the effect of hospital-community integration follow-up pattern on medication compliance in patients with mental disorder. Methods From January 2016 to January 2017, 96 patients were treated effectively with systemic therapy in psychosomatic department and TCM WM department, and 96 discharged mental disorder patients were treated with brief psychiatric rating scale (BPRS) ≤ 28. The patients were randomly divided into 48 cases in the intervention group and the control group; both groups were standardized medication; control group received an outpatient referral, intervention group combined with medical doctors in our hospital and community doctors for one year follow-up intervention. Observed the condition of illness and medication compliance after six months and one year intervention between two groups, compared the patient recurrence rate of one year after discharge. Results BPRS score of intervention group was significantly lower than control group (P＜0. 01), the difference was statistically significant, while intervention group had higher compliance than control group (P＜0. 01), and the difference was statistically significant. Recurrence rate (20. 83％) of intervention group was significantly lower than control group (38. 78％) ( 2 = 4. 03, P＜0. 05), the difference was statistically significant. Conclusion Hospital-community integration follow-up has positive effect on stabilizing patients with mental disorder and improving compliance and decreasing relapse rate.

Objective: To evaluate the efficacy and safety of intravascular ultrasound guidance drug-coated balloon (DCB) in percutaneous coronary intervention (PCI) of situ coronary artery lesions in patients with acute coronary syndrome (ACS), and its effect on thrombus precursor protein (TpP). Methods: Seventy-eight patients with ACS in Central Hospital of Changchun City from January 2015 to January 2019 were selected, including 46 cases with unstable angina pectoris and 32 cases with acute non-ST-segment elevation myocardial infarction. The patients were divided into DCB group (38 cases) and drug-eluting stent (DES) group (40 cases) by random digits table method. Intravascular ultrasound was used to guide PCI in both groups, and DCB and DES were used respectively. Coronary angiography was performed immediately and 6 months after PCI in both groups. Minimum lumen diameter (MLD) was measured by QCA system, and the lumen loss (LLL) was calculated at 6 months after PCI. Plasma TpP before PCI, 1 and 6 months after PCI was measured by enzyme-linked immunosorbent assay (ELISA). Major adverse cardiovascular events (MACE) including cardiac death, myocardial infarction and target lesion revascularization (TLR) were followed up 1, 3, 6 and 12 months after PCI. Results: Immediately after PCI, there was no statistical difference in MLD between DCB group and DES group: (1.87 ± 0.23) mm vs. (2.16 ± 0.15) mm, P>0.05; 6 months after PCI, the LLL in DCB group was significantly smaller than that in DES group: (0.31 ± 0.28) mm vs. (0.48 ± 0.19) mm, and there was statistical difference (P<0.05). There were no significant differences in the incidences of myocardial infarction, TLR and cardiac death in DCB group (P>0.05). Before PCI and 6 months after PCI, there was no statistical difference in TpP between 2 groups (P>0.05); 1 month after PCI, the TpP in DCB group was significantly lower than that in DES group: (15.31 ± 6.13) mg/L vs. (19.46 ± 8.24) mg/L, and there was statistical difference (P<0.05). Conclusions DCB is an accurate and effective treatment for ACS patients with situ coronary artery disease under the intravascular ultrasound guidance, and it can reduce the risk of thrombosis.

Objective: To evaluate the effect of intracoronary injection of recombinant human urokinase on plasma P-selectin in AMI patients with no-reflow during acute PCI. Methods: Ninety-two patients with acute ST-segment elevation myocardial infarction or acute non-ST-segment elevation myocardial infarction admitted to Center Hospital of Changchun City in January 2017 and December 2018 were randomly divided into two groups: 47 patients with intracoronary injection of sodium nitroprusside as control group and 45 patients with intracoronary injection of recombinant human urokinase as treatment group. Among them, 58 were males and 36 were females. The onset time was less than 12 h. The basic data, serum P-selectin, myocardial perfusion index and major adverse cardiovascular events were compared between the two groups. Results: In the treatment group, the corrected TIMI frame number, instant TIMI grade 3 blood flow, myocardial chromogenic grade 3 blood flow, myocardial necrosis marker CTnI, serum P-selectin were significantly lower than those in the control group: 31.26 ± 4.58 vs. 35.15 ± 6.25, 71.1%(32/45) vs. 51.1%(24/47), 64.4%(29/45) vs. 55.3%(26/47), (28.46 ± 3.95) ng/ml vs. (30.18 ± 3.47) ng/ml, (13.26 ± 4.58) ng/ml vs. (15.04 ± 3.98) ng/ml, and EF function was better. In the control group. The incidence of major adverse cardiac events in the treatment group was lower than that in the control group within one month after operation, but there was no statistical significance. Conclusions There is no reflux in patients with AMI during PCI. Intracoronary injection of recombinant human urokinase can improve myocardial perfusion without reflux and has no effect on fibrinolytic system in vivo. It does not increase the risk of systemic hemorrhage and the incidence of serious adverse cardiovascular events.

Objective: : The spontaneous intracerebral hemorrhage (ICH) remains a significant cause of mortality and morbidity throughout the world. The purpose of this retrospective study is to develop multiple models for predicting ICH outcomes using machine learning (ML). Methods: : Between January 2014 and October 2021, we included ICH patients identified by computed tomography or magnetic resonance imaging and treated with surgery. At the 6-month check-up, outcomes were assessed using the modified Rankin Scale. In this study, four ML models, including Support Vector Machine (SVM), Decision Tree C5.0, Artificial Neural Network, Logistic Regression were used to build ICH prediction models. In order to evaluate the reliability and the ML models, we calculated the area under the receiver operating characteristic curve (AUC), specificity, sensitivity, accuracy, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR). Results: : We identified 71 patients who had favorable outcomes and 156 who had unfavorable outcomes. The results showed that the SVM model achieved the best comprehensive prediction efficiency. For the SVM model, the AUC, accuracy, specificity, sensitivity, PLR, NLR, and DOR were 0.91, 0.92, 0.92, 0.93, 11.63, 0.076, and 153.03, respectively. For the SVM model, we found the importance value of time to operating room (TOR) was higher significantly than other variables. Conclusion : The analysis of clinical reliability showed that the SVM model achieved the best comprehensive prediction efficiency and the importance value of TOR was higher significantly than other variables.
