ABSTRACT
Objective To investigate the clinical significance of γ-interferon release test (IGRA) in the diagnosis of entry-exit people with tuberculosis.Methods A total of 64 patients with tuberculosis and 46 healthy people were detected by IGRA,tuberculin skin test (TST),LAM,38× 103 and 16 × 103.The results of different methods were compared and analyzed.Results The sensitivity of IGRA detection method (88.9 ％) and specificity (95.8 ％) were both higher,while the sensitivity (92.7 ％) of the TST method was higher and the specificity (76.7 ％) was lower.Conclusion The sensitivity and specificity of IGRA in the detection of tuberculosis are higher,and it has important clinical application value.
ABSTRACT
Objective To investigate the variations of glomerular function in rabbits with partial unilateral ureteral obstruction (PUUO). Methods Thirty healty adult Japanese White Rabbits were randomly divided into the control group (6 rabbits) and the obstruction group (24 rabbits). The right PUUO model was established according to Cheng′s method. According to the PUUO duration, they were eaqually divided into four subgroups:the 7 day PUUO group, the 14 d PUUO group, the 28 d PUUO group and the 56 d PUUO group. The dynamic renal imaging was performed on all rabbits, and the glomerular filtration rate (GFR) was also calculated. The correlation between the renal function and PUUO duration was analyzed , and functional variations in the healthy kidneys were observed. Results (1)To the control group, no significant difference in the renal function was found between the left and the right kidneys (t = -0.145, P = 0.894). However, to the PUUO group, the right renal GFRs were significantly lower than the left renal GFRs (P 0.05), (3)No significant differences were found in the left renal GFRs among the five groups. Conclusions The function of PUUO kidneys is characterized by an obvious decrease in the early stage, followed with a steady state. The basic function of the opposite healthy kidney does not present the compensation phenomenon.
ABSTRACT
Objective To investigate the correlation between plasma von Willebrand factor(vWF) and the extent of coronary artery lesion in acute coronary syndrome (ACS).Methods One hundred and forty eight ACS patients (ACS group) who performed coronary angiography (CAG) were divided into single stenosis group (54 patients),double stenosis group (51 patients) and multitude stenosis group (43 patients) by the number of stenosis through CAG.They were divided into mild group (Gensini score ≤ 20 points,31 patients),midrange group (Gensini score 21-40 points,47 patients) and severe group (Gensini score ≥ 41 points,70 patients).Fifty patients with stable angina pectoris (SA) were randomly selected and classified as SA group,while 50 patients with healthy coronary were randomly selected as control group.Blood sample of 248 patients were collected to detect the level of vWF,and blood routine examination,blood clotting function,liver and renal function,high sensitivity C-reactive protein (hs-CRP),blood glucose,blood fat were detected.The correlation between vWF and the extent of coronary artery lesion were analyzed.Results The level of white blood cell count (WBC) and hs-CRP in ACS group were significantly higher than those in SA group and control group (P ＜ 0.05).But the level of WBC and hs-CRP between SA group and control group had no significant difference (P ＞ 0.05).The level of blood platelet count,prothrombin time,partial prothrombin time,fasting blood glucose,thrombin time,2 h postprandial glucose,triglyceride,total cholesterol had no significant difference among three groups (P ＞ 0.05).The level of vWF in ACS group was significantly higher than that in SA group and control group [(143.25 ± 20.42)％ vs.(102.77 ± 11.84)％,(97.63 ± 10.31)％] (P ＜0.05).The level of vWF in single stenosis group,double stenosis group and multitude stenosis group was (127.34 ± 9.35)％,(144.81 ± 12.02)％,(159.55 ± 18.62)％,and significantly higher than that in control group (P ＜ 0.01).The level of vWF in mild group,midrange group and severe group was (124.77 ± 14.31)％,(132.53 ± 16.38)％,(155.06 ± 18.53)％,and significantly higher than that in control group (P ＜ 0.01).The level of vWF had significantly positive correlation with the number of stenosis and Gensini score (r =0.698,0.683,P ＜ 0.01).Conclusion The level of vWF in peripheral blood is closely related with the severity of ACS and has important clinical significance in evaluating the condition and guiding therapy in patients with ACS.
ABSTRACT
Objective To investigate a reproducible model of severe crush injury (CI) in rats.Methods A total of 50 clean grade male SD rats were randomly (random number) divided into 5 groups.Both hindlimbs of anesthetized rats were compressed by blocks weighing 3.5 kg,for 6 hours and followed by 3 hours of reperfusion on a specially notched device (group SP,n =10),ordinary compression (group NM,n =10) and simple control (group SHAM,n =10).Arterial tension,serum lactate,and potassium (K+),serum myoglobin (MB),aspartate transferase (AST) and alanine transferase (ALT),BUN and Cr were measured at 10 minutes after cannulaton,and 3 hours after release from compression.Muscles and kidneys were evaluated morphologically.Group D and E were treated in the same way and were observed for 72 h to get the survival rate of the NM group and the specially notched compression group.The SPSS 17.0 statistical software was used for statistical analysis,repeated-measures ANOVA analysis for the differences between groups,Kaplan Meier-estimator for survival analysis.Results The Specially notched compression produced a greater increase in serum lactate (F =39.626,P ＜ 0.05),AST (F =24.965,P ＜ 0.05),ALT (F =19.096,P＜0.05),BUN (F=7.938,P＜0.05),CR (F=14.787,P＜0.05) and MB (F=16.840,P ＜0.05) by the end of experiment than NM group and simple control group.The direct cellular damage and ischemia-reperfusion injury were found under microscope.In crush injury caused by specially notched compression there was acute tubular necrosis found at 24 hours after injury.Mortality rate in the NM group was 20％,whereas mortality rate reached 90％ in rats with specially notched compression (P ＜0.05).Conclusions It successfully developed a severe crush injury model in experimental rats,suggesting it is worthwhile to popularization.
ABSTRACT
Retrospective analysis was conducted for the results of first-aid competitions so as to understand the present status of how emergency doctors of Hubei Province grasp the skills and consciousnesses of cervical immobilization.From 6 out of 19 teams,38 participating doctors from grade 3A hospitals provided patient cervical immobilization while 2 teams offered no cervical protection.It is necessary to intensify the skills and consciousnesses of cervical immobilization in clinical practice.
ABSTRACT
Objective To evaluate the efficacy of multiple injection of morphine combined with phloroglucinol in the treatment of renal colic. Methods One hundred and twenty patients with severe renal colic were equally divided into three groups by random digits table,with 40 cases each group. The group A was administrated with physiological saline 100 ml and phloroglucinol 80 mg intervenous drop infusion combined with morphine 9 mg intravenous injection fractionated into three times, and the group B was administrated with physiological saline 100 ml and phloroglucinol 80 mg intervenous drop infusion,and the group C was administrated with physiological saline 100 ml intervenous drop infusion and morphine 9 mg intravenous injection fractionated into three times. At 10,20 and 40 min after administration, the antalgic efficacy of three groups were analyzed as well as the side effect. Results At 20 min and 40 min both of the total efficacy rates in group A[82.5%(33/40),95.0%(38/40)] were higher than those in group B [62.5%(25/40),80.0%(32/40)] and group C [60.0%(24/40),77.5%(31/40)] (P＜ 0.05),and the colic-exclusion rate in group A was also higher than that in group B and group C (P ＜ 0.05). The difference of the efficacy rates in group A in these two time-points had no statistical significance (P ＞0.05). No increased pain occurred in group A except 1 case of vomiting. Conclusion Multiple injection of morphine combined with phloroglucinol is quick, effective and safe in the early treatment of renal colic.
