Objective:To investigate the expression of serum caspase-cleaved cytokeratin 18(CCCK-18) in patients with cerebral ischemic stroke and its diagnostic value.Methods:One hundred and six patients with cerebral ischemic stroke who were diagnosed and treated in Affiliated Dongfeng Hospital from October 2018 to October 2019 were selected as the study group. Ninety patients who underwent digital subtraction angiography (DSA) during the same period and showed no other abnormalities inside or outside the skull were selected as control group. The baseline data of gender, age, drinking history, smoking history, hypertension history, diabetes history, coronary heart disease, and other subjects in the two groups had no significant differences ( P>0.05). Cubital venous blood of 5 ml from two groups of subjects were collected, and the level of serum CCCK-18 was detected by enzyme-linked immunosorbent assay. The levels of total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) were detected by enzymatic method. The receiver operating characteristic curve (ROC curve) was used to analyze the diagnostic efficacy of serum CCCK-18 in patients with ischemic stroke, and the relationship between serum CCCK-18 and TC, TG, LDL-C, HDL-C were analyzed by Pearson test. Results:The levels of serum CCCK-18, TC, TG, and LDL-C in the study group were significantly higher than those in the control group: (158.10 ± 50.89) U/L vs. (85.57 ± 35.25) U/L, (4.26 ± 0.92) mmol/L vs. (3.92 ± 0.80) mmol/L, (2.34 ± 0.53) mmol/L vs. (1.83 ± 0.47) mmol/L, (3.12 ± 0.73) mmol/L vs. (2.61 ± 0.67) mmol/L, and HDL-C level was lower than that in the control group: (1.20 ± 0.24) mmol/L vs. (1.32 ± 0.28) mmol/L, and there were significant differences ( P<0.05). Logistic regression analysis showed that CCCK-18, TC, TG, LDL-C, and HDL-C were independent risk factors for patients with ischemic stroke ( P<0.05). The area under the curve(AUC) of serum CCCK-18 to distinguish ischemic stroke from the control group was 0.878, with a sensitivity of 84.91% and a specificity of 78.89%. The AUC of serum CCCK-18 to identify patients with mild ischemic stroke was 0.763, with a sensitivity of 70.37% and a specificity of 78.89%. Correlation analysis showed that serum CCCK-18 was positively correlated with TC, TG, and LDL-C in patients with ischemic stroke ( r = 0.711, 0.722, 0.705), and negatively correlated with HDL-C ( r = - 0.714), and there were significant differences ( P<0.01). Conclusions:Serum CCCK-18 levels are significantly increased in patients with cerebral ischemic stroke, which can be used as a biomarker for diagnosis and judgment of disease severity.

Objective: To evaluate the feasibility of performing muscle-sparing thoracotomy and intercostal sutures in the treatment of upper and/or middle thoracic esophageal cancer for the purpose of tumor control and postoperative quality of life improvement.Methods: Seven patients with esophageal cancer were treated with vertical muscle-sparing thoracotomy and Mckeown esophagectomy.Detailed clinic data were summarized and analyzed with patient follow-up information.Results: Of the 7 patients,five were still alive with a 71.4% five-year survival rate.There were no deaths resulting from the operation in this group.The mean length of thoracic incision was 11 cm.The range of hospital stays was 14 to 25 days,with a mean length of 18 days.No patients complained of impaired shoulder action,and the incision pain was hardly perceived without external stimulation 1 month after operation.Conclusion: Performing the muscle-sparing thoracotomy in the treatment of early-stage esophageal cancer located in the upper and /or middle thoracic segment yields a satisfactory long-term survival rate with an improved life quality in terms of incision pain relief and shoulder function.

OBJECTIVE:To study the consistency policies of generic drugs in China,America and Japan comparatively,and provide reference for perfecting quality and efficacy consistency evaluation of generic drugs in China. METHODS:Generic drugConsistency evaluationQuality evaluationDESIwere used as keywords to search the related literatures or information of ge-neric drugs published or reported in CNKI,Web of Science,Elsevier,Springer database and USA FDA website during Jan. 1st, 1950-Jun. 30th,2016. And comparative analysis was conducted for the historical background,evaluation methods and policy influ-ences of consistency policies of generic drugs in China,America and Japan. RESULTS:There were differences in the historical background,evaluation methods,major participants and policy influences of consistency policies of generic drugs in China,Ameri-ca and Japan. The evaluation for generic drugs in USA was reevaluation of the drugs effectiveness under the history of drug registra-tion regulation was imperfect. With experts'review,it was evaluated based on FDA,enterprises,scientific literature evidence and experts review. Main evaluation method was in vitro dissolution test in Japan. The consistency evaluation of generic drug in China focused on the generic drug marketing authorization,mainly using in vivo bioequivalence. And the standards of reference prepara-tions were from the basically similar drugs to the original drugs. CONCLUSIONS:Compared with innovation-based countries like America and Japan,the availability of reference preparations in China is low,and policy environment is more complex. China should further improve the laws and regulations,giving reasonable buffer period,considering the diversity of evaluation methods, exemptions in special circumstances and current situation of pharmaceutical industry,paying attention to the balance between techni-cal supervision and system supervision.

Objective To investigate the effects of inhibitor of growth 4(ING4)on the proliferation,migration and the expression of angiogenesis related factors such as VEGF,MMP-2,MMP-9 in endothelial cells. Methods Human umbilical vein endothelial cells(HUVECs)were cultured in vitro;ING4 plasmid and siRNA were constructed and transfected to HUVECs;the proliferation of HUVECs was evaluated by MTT assay;the ability of migration was evaluated by Transwell assay;real-time PCR and Western blotting were used to determine the expression of mRNA and pro-tein of angiogenesis related factors such as VEGF,MMP-2,and MMP-9. Results MTT and Transwell assay showed that ING4 has the ability to inhibit the proliferation and migration of HUVECs,and the results of real-time PCR and Western blotting proved that ING4 can inhibit the expres-sion of angiogenesis related factors such as VEGF,MMP-2,and MMP-9. Conclusion ING4 can inhibit the proliferation and migration of HU-VECs,down-regulate the expression of angiogenesis related factors such as VEGF,MMP-2,MMP-9,and inhibit angiogenesis.

Hospital acquired infection (HAI) is one of the common complications of hospitalized patients and poses a serious threat to public health worldwide, which causes an exacerbation, prolonged hospitalization and increased medical costs. Because of higher illness severity and more invasive operations, patients in neurosurgical intensive critical unit (NICU) are more susceptible to HAI such as hospital acquired pneumonia (HAP) and surgical site infection (SSI), leading to theincrease of mortality. Therefore, the prevention and treatment of HAI is an important challenge during the treatment of diseases in NICU. In this paper, we summarized the common types, pathogenic characteristics, prevention measures and antimicrobial treatment of HAI in NICU, aiming to provide ideas and reference on HAI treatment for medical personnel in NICU.
