OBJECTIVE: To analyze the effect of mechanical cardiopulmonary resuscitation (CPR) on patients with cardiac arrest with the vertical spatial pre-hospital emergency transport. METHODS: A retrospective cohort study was conducted. The clinical data of 102 patients with out-of-hospital cardiac arrest (OHCA) who were transferred to the emergency medicine department of Huzhou Central Hospital from the Huzhou Emergency Center from July 2019 to June 2021 were collected. Among them, the patients who performed artificial chest compression during the pre-hospital transfer from July 2019 to June 2020 served as the control group, and the patients who performed artificial-mechanical chest compression (implemented artificial chest compression first, and implemented mechanical chest compression immediately after the mechanical chest compression device was ready) during pre-hospital transfer from July 2020 to June 2021 served as the observation group. The clinical data of patients of the two groups were collected, including basic data (gender, age, etc.), pre-hospital emergency process evaluation indicators [chest compression fraction (CCF), total CPR pause time, pre-hospital transfer time, vertical spatial transfer time], and in-hospital advanced resuscitation effect evaluation indicators [initial end-expiratory partial pressure of carbon dioxide (P_ETCO₂), rate of restoration of spontaneous circulation (ROSC), time of ROSC]. RESULTS: Finally, a total of 84 patients were enrolled, including 46 patients in the control group and 38 in the observation group. There was no significant difference in gender, age, whether to accept bystander resuscitation or not, initial cardiac rhythm, time-consuming pre-hospital emergency response, floor location at the time of onset, estimated vertical height, and whether there was any vertical transfer elevator/escalator, etc. between the two groups. In the evaluation of the pre-hospital emergency process, the CCF during the pre-hospital emergency treatment of patients in the observation group was significantly higher than that in the control group [69.05% (67.35%, 71.73%) vs. 61.88% (58.18%, 65.04%), P < 0.01], the total pause time of CPR was significantly shorter than that in the control group [s: 266 (214, 307) vs. 332 (257, 374), P < 0.05]. However, there was no significant difference in the pre-hospital transfer time and vertical spatial transfer time between the observation group and the control group [pre-hospital transfer time (minutes): 14.50 (12.00, 16.75) vs. 14.00 (11.00, 16.00), vertical spatial transfer time (s): 32.15±17.43 vs. 27.96±18.67, both P > 0.05]. It indicated that mechanical CPR could improve the CPR quality in the process of pre-hospital first aid, and did not affect the transfer of patients by pre-hospital emergency medical personnel. In the evaluation of the in-hospital advanced resuscitation effect, the initial P_ETCO₂ of the patients in the observation group was significantly higher than that of the patients in the control group [mmHg (1 mmHg ≈ 0.133 kPa): 15.00 (13.25, 16.00) vs. 12.00 (11.00, 13.00), P < 0.01], the time of ROSC was significantly shorter than that in the control group (minutes: 11.00±3.25 vs. 16.64±2.54, P < 0.01), and the rate of ROSC was slightly higher than that in the control group (31.58% vs. 23.91%, P > 0.05). It indicated that continuous mechanical compression during pre-hospital transfer helped to ensure continuous high-quality CPR. CONCLUSIONS Mechanical chest compression can improve the quality of continuous CPR during the pre-hospital transfer of patients with OHCA, and improve the initial resuscitation outcome of patients.

Objective To evaluate he significance of the Neutrophil-Lymphocyte Ratio(NLR)and the red blood cell(erythrocyte)distribution width(RDW)in distinguishing between simple and complex febrile seizures and evaluate the diagnostic values of NLR and RDW in febrile seizures. Methods Totally,100 patients aged between 6 months and 5 years diagnosed with febrile seizure were admitted to the emergency department of the hospital.Complete blood count obtained from the peripheral blood samples collected from the patients at admis-sion were evaluated. Results The average values of NLR for simple and complex seizure groups were 2.16 ± 1.26 and 3.62 ± 1.51 respectively.The average values of RDW for simple and complex seizure groups were 15.04 ± 1.73 and 16.89 ± 1.44,respectively.Using receiver operating characteristic curve(ROC),the sensitivity and specificity were 65.5% and 66.2%,respectively,with the area under the curve[AUC]of 0.670 when the cut-off value was 2.52 for NLR,and they were 62.1% and 59.3%,respectively,with AUC of 0.619 when the cut-off value was 16.47 for RDW. Conclusion NLR and RDW may provide clinicians with an insight into differentiation between simple and complex febrile seizures,however,we need much better diagnostic value to classify the febrile seizures

Objective To study the expression and clinical significance of miR-183-5p, TβRⅠ and TβRⅡ in esophageal squamous cell carcinoma (ESCC). Methods The mRNA and protein expression of miR-183-5p, TβRⅠ and TβRⅡ were examined in ESCC cell lines ECA-109, TE-1, normal esophageal epithelial cells, tumor tissues and tumor-free tissues from 72 ESCC patients. Their clinical significance and the relationship between miR-183-5p and the latter two were analyzed. The effects of miR-183-5p on the expression of TβRⅠand TβRⅡ in ECA-109 cells and the cell functions of ECA-109 were also investigated. Results Compared with the normal esophageal epithelia cells, ESCC cell lines TE-1 and ECA-109 were statistically characterized by a high expression of miR-183-5p (all P<0.05) and low expression of TβRⅠand TβRⅡ(all P<0.05). The expression of miR-183-5p in ESCC tissues was higher than that in adjacent normal tissues, while the expressions of TβRⅠ and TβRⅡ were lower (all P< 0.05). The expression of miR-183-5p was closely related to sex, tumor differentiation, tumor staging, distant metastasis, lymphatic metastasis, and tumor location (all P<0.05). TβRⅠlevel was associated with sex, lymph node metastasis and tumor size (all P<0.05). Experimental data showed the negative correlation between the expression of miR-183-5p and TβRⅠin ESCC tissues (r= -0.521, P< 0.05). Over expression of miR-183-5p significantly inhibited the expression of TβRⅠ in ECA-109 cells (P< 0.05) and promoted the growth, invasion and metastasis of ECA-109 cells (P< 0.05). Low expression of miR-183-5p significantly promoted the expression of TβRⅠ in ECA-109 cells (P< 0.05), and suppressed the growth, invasion and metastasis of ECA-109 cells (P< 0.05). There was no significant change in the expression of TβRⅡ in the transfection experiments. Conclusion MiR-183-5p is closely related to the abnormal expression of TβRⅠ, which may exert an important role in the progression of lymphatic metastasis.
