Objective:To strengthen the safety management of monitor according to the analysis of risks in the process of using multi-parameter monitor.Methods:1200 multi-parameter monitors were investigated in the 25 medical units for monitor safety risks using statistical methods, to investigate and analyze the risk within three years and classified the related factors. Results: Within three years, there were 420 cases with security risks in 1200 sets of multi-parameter monitor, including 220 cases with clinical application, 120 cases with equipment management problems, and 80 cases with maintenance problems. Clinical operation of multi-parameter monitors problems led to safety risks with high proportion.Conclusion:Multi-parameter monitor safety risk is mainly caused by improper use in clinical. It can ensure the safety of multi-parameter monitor in clinical on strengthening ideological understanding, improving the clinical training, and paying attention to the maintenance.

Objective To study the clinical significance of interleukin (IL)-6 and IL-13 levels in serum of hand,foot,and mouth disease (HFMD)caused by enterovirus 71,and carries on the preliminary discussion on serum IL-6 and IL-13 cell origin. Methods Serum levels of IL-6 and IL-13 in HFMD and healthy control were detected by enzyme linked immunosorbent assay (ELISA),serum IL-6 and IL-13 levels among different severity of HFMD were compared.Serum IL-6 and IL-13 levels in HFMD after treatment were also detected.The secretion of IL-6 by monocyte and the secretion of IL-13 by T cells in peripheral blood mononuclear cells (PBMC)were detected by Flow Cytometry (FCM).Monocyte and T cells from health individual were treated with EV71,and the secretion of IL-6 by monocyte and the secretion of IL-13 by T cells were detected by FCM too.Results Serum levels of IL-6 and IL-13 were (79.63±29.45)pg/mL and (36.45±1 5.13)pg/mL respectively in HFMD,and serum levels of IL-6 and IL-13 were (27.26±7.82)pg/mL and (13.46±3.14)pg/mL respectively in health control,serum IL-6 and IL-13 levels in HFMD were significantly higher than that of healthy subjects (P < 0.01 ),and the mean serum IL-6 and IL-13 levels of HFMD were increased with the severity of the disease (P <0.01).After treatment,serum levels of IL-6 and IL-13 were (48.23 ±23.14) pg/mL and (23.25±9.63)pg/mL respectively,when compared with before treatment,serum levels of IL-6 and IL-13 were signifi-cantly decreased (P <0.01).The secretion ability of IL-6 by monocyte and the secretion of IL-13 by T cells in HFMD were signifi-cantly higher than that of healthy subjects.After infection by EV71,the secretion ability of IL-6 by monocyte and the secretion of IL-13 by T cells were significantly increased.Conclusion Infection of EV71 probably by increase the secretion ability of IL-6 by monocyte and the secretion of IL-13 by T cells,resulted in elevated of serum IL-6 and IL-13 levels,which involved in the occurrence and development of HFMD.

Objective To investigate the effects of recombinant human interferon α2a(rhIFNα2a) suppository on the levels of inflammatory factors in the cervical mucus of patients infected with human papillomavirus(HPV).Methods A total of60 HPV-positive patients admitted to the Second Affiliated Hospital of Xi'an Jiaotong University from March to August in 2022 were selected as study objects,and then divided into observation and control groups,30 cases for each group,according to the random number table method.The observation group was given rhIFNα2a suppository therapy by vaginal medication,once every other day,continuous 10 times a month as a course of treatment,and 3 consecutive courses of treatment.The control group did not use drugs.The cervical secretions were collected and the levels of IL-1β,IL-2R,IL-6,IL-8,IL-10 and tumor necrosis factor-α(TNF-α) were measured by chemiluminescence assay.Results After 3 months of treatment,the levels inflammatory factors IL-1β,IL-6,IL-8 and TNF-α in cervical mucus of patients in the observation group were significantly lower than those in the control group(t=-2.717,-2.686,-3.178 and-3.25,respectively,each P <0.05).Compared with before treatment,the levels of IL-1β,IL-6,IL-8 and TNF-α in cervical mucus of patients in the observation group also decreased significantly(t=5.934,4.092,6.495 and 3.287,respectively,each P <0.01),while in the control group,only the level of IL-8 in cervical mucus was significantly different(t=2.345,P=0.024).Conclusion rhIFNα2a suppository can reduce the level of inflammatory factors in cervical mucus,attenuate the inflammatory response and accelerate the clearance of HPV.

Objective To find out the effect of tooth preparation and bonding agents on cementation of metal full crown,to provide research basis for clinical practice of full crown restoration .Methods 60 dissociation teeth were randomly divided into six groups ,10 teeth in each group .Different adhesive materials or different polymerization angle were used in different groups ,the six groups were 3 polymerization angle zinc group ,3 polymerization angle glass ionomer group,3 polymerization angle resin cement group ,5 polymerization angle zinc group ,5 polymerization angle glass ionomer group ,and 5 polymerization angle resin cement group .In the first three groups ,polymerization angle was 3,and in the latter three groups ,polymerization angle was 5.The retentive force values of all groups were tested and compared.Results The metal crown retentive force of 3 polymerization angle zinc group[(198.5 ±11.6)N]was sig-nificantly better than that of 5 polymerization angle zinc group[(138.2 ±14.1)N](t=7.46,P<0.05).Polymeriza-tion angle showed no statistically significant effect on metal crown retentive force values of glass ionomer groups and resin cement groups (t=1.52,2.03,all P>0.05).Bonding zinc retention of 3 degree of polymerization group was (198.5 ±11.6)N,glass ionomer and resin cements were (302.7 ±19.2) N and (352.7 ±21.8) N.Bonding zinc retention of 5 degree of polymerization group was (138.2 ±14.1)N,glass ionomer and resin cements were (317.4 ± 23.8)N and (362.9 ±22.6) N.Different adhesives showed statistically significant effects on metal crown retentive force values of 3 polymerization angle groups and 5 polymerization angle groups (F=7.88,8.42,all P<0.05). Conclusion A suitable adhesive,standard operation can get the best cementation effect ,and improve clinical repair effect.

Ebola virus, the cause of severe and fatal hemorrahagic fever in humans, belongs to filovirus family. This study was designed to establish a cell-based screening and evaluation system in the pharmacological study of antivirus compounds. Three reporter systems were established with recombinant pseudoviral luciferase of HIV core (pNL4-3.Luc.R(-)E(-)) packed with filovirus glycoprotein (EBOV-Zaire GP/HIV-luc, EBOV-Sudan GP/HIV-luc and Marburg GP/HIV-luc), which are required for virus entry of cells. The level of filovirus entry was determined by the expression of luciferase reporter gene in the infected cells. For screening of filovirus entry inhibitors, the vesicular stomatitis G packed pseudovirions (VSVG/HIV-luc) was used to determine the compound specificity. The results of known filovirus entry inhibitors demonstrated successful establishment of the new model systems, which would be useful in high throughput screening of anti-filovirus drugs in the future.

Objective To explore the clinical effect of one new type of short section pedicle of vertebral arch nail system(internal fixation system by nail-stick) on patients with thoracolumbar fracture.Methods 68 patients with thoracolumbar fracture were selected.Internal fixation system by nail-stick was used on the patients with thoracolumbar fracture,the clinical effect was observed.Results After following up for six to eighteen months,the vertebral height was measured by X-ray.The anterior edge height of the vertebral was 47% before operation and 94% after operation,the posterior edge height of the vertebral was 76% before operation and 97% after operation,there was significant difference between preoperation and post operation(P<0.01).All the cases with AF intemal fixation system had better clinical effect,18 cases had satisfactory effect.Except that the neurological deficits of 4 cases had not been improved,those of the other cases all had been impreved at some degree.Conclusion Thoracolumbar fracture should be treated early,AF imtermal fixation system has significant effect on the thoracolumbar fracture,the skilled performance is important during the operation,and contraindications of internal fixation system by nail-stick should be noticed.
