Analysis of respirtory virus IgM antibodies detection in patients with respiratory tract infection in emergency wards / 国际检验医学杂志

Objective To understand the distribution situation of respiratory viral infection among adult inpatients with respiratory infection in the emergency department.Methods The detection results data of 5 kinds of viruses RSV,IVA,IVB,PIV1,PIV2,PIV3 and ADV by indirect immune fluorescence assay in 384 adults patients with respiratory infection in the emergency department of our hospital from January 2014 to December 2015 were collected.The epidemic characteristics of different viruses were analyzed.Results Among 384 specimens,208 cases were positive in respiratory virus IgM antibody,the viral infection positive rate was 54.17%.The mixed virus infection and influenza B virus infection were most common,their viral positive rates were 26.56% and 23.44% respectively,In the mixed viral infection,the positive rate of IVA + IVB mixed infection was highest,accounting for 87.25%,which was higher than that of other kinds of mixed viral infection.The viral infection positive rate had no statistical difference between different genders(P>0.05).The viral infection rate was higher in autumn and winter,which were 66.06% and 68.37% respectively and higher than 42.31% and 34.25% in spring and summer,the difference was statistically significant(P45-60 years old) were 64.94% and 63.86% respectively,which were higher than 48.45%,44.92% and 55.56% in pre-elderly (>60-75 years old),elderly (>75-90 years old) and longevous elderly (>90 years old),the differences were statistically significant(P<0.05).Conclusion The respiratory virus mixed infection and IVB infection are most common in the emergency wards,moreover the viral infection situation shows the seasonal and age characteristics,but which is not affected by sex factor.

Clinical research on Angongniuhuang pill adjuvant to haloperidol for the treatment of intensive care unit patients with postoperative delirium / 中华急诊医学杂志

Objective To observe the clinical effects and safety of Angongniuhuang Pill (a traditional Chinese medical preparation)adjuvant to haloperidol for the treatment of Intensive Care Unit (ICU)patients in postoperative delirium.Methods A prospective study of 243 postoperative patients with delirium adimitted in Intensive Care Unit of Xinjiang Medical University First Affiliated Hospital (January 2013-December 2014),by using confusion assessment method of Intensive Care Unit (CAMICU).All of 243 patients with delirium were randomly divided into two groups by computer randomization software (SAS 9.1):group A in which patients were treated with Angongniuhuang Pill adjuvant to haloperidol and group Fin which patiets were treated with haloperidol alone.The end of two intervention methods was determined by two consecutive CAMICU showing negative or the treatment were ended up at seven days treatment.The data of general information,and the results of treatment were recorded and analized by statistical software SPSS 19.0.The measurement data was expressed as mean ±standard deviation;the comparision between two groups was tested by t test;and repeated measurement was analised by variance.Count data was described as number and constitution ratio;and intergroup comparision was tested by Chi-square test. Results There was no significant difference in general information between two groups.The delirium duration and ICU treatment time in group A were shorter than those in group F [(3.0 ±0.9)d vs.(3.8 ±1.0) d,P =0.010; (6.2 ± 1.4) d vs.(6.7 ± 1.5) d,P = 0.008].When delirium was diagnosed (T0),all patients had EEG abnormalities.As treatment went on,EEG abnormal rate gradually declined.At day one (T1),there was no statistically significant difference in EEG findings between group A and group F (95.7% vs.97.5%,P = 0.045 ).At day two (T2 )and day three (T3 ),there was statistically significant difference in EEG findings between group A and group F (65.5% vs.77.7%,P =0.038;42.2% vs.56.2%,P = 0.032).The levels of S100βprotein,interleukin-6 (IL-6),tumor necrosis factor α(TNF-α)in two groups at T0 were all elevated without noticeable difference.These markers were all deceased at T1,T2,T3,but the speed of descend in group A was relatively faster than that in group F.The differences were statistically significant (S100β:time effect P <0.01,inter-group effectp =0.002,interaction effectp =0.686;IL-6:time effect P <0.01,inter-group effectp =0.034,interaction effectp =0.01;TNF-α:time effect P <0.01,inter-group effectp =0.003,interaction effectp =0.516). The discharge rate in group A after improvement of general condition was higher than that in group F (89.7% vs.79.3%,P =0.029).The incidence of postoperative complications and mortality 28 days after operation in group A were lower than those in group F (45.7% vs.58.7%P =0.045;12.9% vs. 24.0%,P =0.028).Conclusion During the treatment of delirium,Angongniuhuang pill adjuvant to haloperidol was a better method compared with using haloperidol alone in respect of effectiveness and safety perspectives.It may be a novel approach to the treatment for delirium by the combination of Chinese and Western medicine.

Detection of serum hyper sensitive C-reactive protein level in patients with acute ischemic stroke and its clinical significances / 国际检验医学杂志

Objective To explore the level of hypersensitive C-reactive protein (hs-CRP)in the patients with acute ischemic stroke(AIS)and its clinical significance.Methods The BNⅡhighly sensitive automatical scattering turbidimetric immunity analy-zer was adopted to detect serum hs-CRP level in 64 cases of AIS and contemporaneous 32 individuals with healthy physical examina-tion as the control group.The data of AIS cases were retrospectively analyzed.Results The positive rate of hs-CRP was 53.3% in the AIS group and 9% in the control group with statistically significant difference between them(P <0.05);the overall levels of hs-CRP in the AIS group was in inconformity to the normal distribution,the median was 4.26mg/L,which in the control group was (0.99 ± 0.72 )mg/L,there was statistically significant difference between them (P < 0.05 );the average level of hs-CRP was (5.03±1.51)mg/L in the AIS male group and (2.79 ± 1.09)mg/L in the AIS female group,the difference between them had sta-tostical significance(P <0.05).Conclusion The serum hs-CRP level in the AIS patients is higher than that in the healthy crowd with statistical difference(P <0.05).The age and sex may be the causes influencing serum level of hs-CRP in the AIS patients.The average age in the AIS patients with positive hs-CRP is higher than that with negative hs-CRP.Middle-aged and elderly people with hypertension and diabetes are much more dangerous than healthy people in getting AIS.

Diagnostic performance of HCV antibody and RNA Determination / 国际检验医学杂志

Objective To explore changes of anti-HCV antibody and HCV-RNA in patients with HCV infection and its clinical significance in diagnosis and treatment of hepatitis C .Methods Serum samples from patients with HCV infection were collected . HCV antibodies were analyzed with a chemiluminescence micro-particle immunoassay method ,while a PCR-fluorescent probe meth-od was used to detect HCV-RNA .Concentrations of ALT and AST were also determined .Based on the concentrations of ALT , AST and HCV-RNA ,samples were divided into two groups respectively and the changes of different indicators were analyzed and compared .Meanwhile samples from 37 HCV-infected patients were collected continuously .Different indicators after treatment were compared with those before treatment .Results HCV-Ab and logarithm values of RNA load in the group with abnormal concentra-tions of ALT and AST were significantly higher than those in the normal group (P0 .05) .Conclusion The diagnostic performance of HCV-Ab is better than that of logarithm values of RNA load .Determination of ALT ,AST and HCV-RNA is of clinical importance in monitoring the effect of hepatitis C treatment .
