Objective To investigate the clinical value of combining early urine paraquat early clearance rate (UPCR) with severity index of paraquat poisoning (SIPP) in predicting the prognosis for paraquat poisoning patients.Methods In this retrospective research,a total of 425 cases diagnosed with acute paraquat poisoning from March 2014 to March 2016 in Emergency Intensive Care Unit,First Affiliated Hospital of China Medical University were enrolled.The general data of patients,the results of rapid qualitative test of paraquat in blood and urine,the concentration of paraquat in blood / urine,the poisoning time,the concentration of blood lactic acid and the APACHE Ⅱ score were collected.The early UPCR and SIPP were measured at different time intervals,and the ratio of 6-SIPP and 12 h-UPCR were calculated.These patients were divided into death groups and survival groups according to the 28-day mortality.The relationship between these factors and the mortality were analyzed.Results Of all the 425 patients,268 cases (63.1％) died,157 cases (36.9％) survived;the blood concentration of paraquat,the lactate concentration,SIPP values and the APACHE Ⅱ scores were significant difference between the two groups (P ＜ 0.05).The mortality of 2-6 hour paraquat rapid qualitative test result positive patients was higher (96.4％) than that of the negative patients (3.6％) (P ＜ 0.05);the mortality of 12-24 hour paraquat rapid qualitative test result negative patients was lower (11.5％) than that of the positive patients (88.5％) (P＜0.05).The 2-6 hour SIPP value was 19.8 ±6.7 in death group,which was higher than that in survival group (4.9±3.1) (P＜0.05);the 2-6 hour UPCR value was (41.7±9.3) indeath group,which was lower than that in survival group (86.3 ± 15.8) (P ＜ 0.05).There was no significant difference in the 2-6 hour UPCR value and 12-24 hour UPCR value between two groups (P ＞0.05).The 6 h-SIPP/12 h-UPCR value was (41.94 ±5.9) in death group,which was higher than that in survival group (5.27 ± 3.6) (P ＜ 0.05).Conclusion The combined use of early UPCR and SIPP values is an effective indicator of the prognosis of patients with acute paraquat poisoning and is helpful for the early stratification.We should pay more attention to the patients whose rapid qualitative blood test is positive because of their high mortality risk;for the patients whose 12 h urinequalitative test was negative,the hemoperfusion therapy might be stopped because the toxin was completely excluded,and the medical resources can be saved reasonably.The UPCR might indicate the excretion of toxins,and SIPP might indicate the severity of poising.

Objective To investigate the joint value of early peak temperature and 48 h-△sequential organ failure assessment (SOFA) score in predicting the prognosis for patients with sepsis in emergency department.Methods Two hundred and thirty-one patients with sepsis admitted from January 2013 to January 2015 in Emergency Intensive Care Unit of the First Affiliated Hospital of China Medical University were enrolled.Clinical features,early peak temperature,SOFA scores,the length of stay in EICU and the mortality in 28 days were studied.The patients were divided into two groups according to the 48 h-△SOFA.Each group were divided into three subgroups according to the early peak temperature.For example,hypothermia subgroup had temperature below 36 ℃,normothermia subgroup had temperature between 36 ℃ and 38 ℃,and hyperthermia subgroup had temperature above 38 ℃.The relationship between peak temperature plus 48 h-△SOFA and the length of stay in EICU as well as mortality were analyzed.Results Of 231 patients,in 48 h-△SOFA＞0 group (n =142) 27 (19.0％) patients died,and in 48 h-△SOFA≤0 group (n =89) 33 (37.1％) patients died (P ＜ 0.05).Hypothermia subgroup had a higher odds ratio value in predicting nonsurvival in 48 h-△SOFA≤0 group (OR =4.51,95％CI:1.33-2.17,P =0.01).Hyperthermia subgroup had a longer stay in EICU than hypothermia subgroup and normothermia subgroup (P ＜ 0.05).Conclusion The combination of the early peak temperature and 48h-△SOFA score is an effective indicator to evaluate the prognosis and to stratify patients with sepsis in emergency department.More attention should be paid to the patients with an early peak temperature ＜ 36 ℃ and 48 h-△SOFA ≤0 because of higher mortality.The condition of patients should be reassessed and try to make a more rational treatment for the patients with an early peak temperature ＞38 ℃ and 48 h-△SOFA ＞0 because of its longer stay in EICU.

Objective To evaluate clinical effect and safety of direct hemoperfusion with neutral resin (NS-DHP) on patients with septic shock caused by Gram-negative bacteria infection.Methods A total of 42 patients were enrolled in the study and randomly ( random number) divided into two groups.Patients of control group ( n =24) received sepsis bundle therapy,and patients of group D ( n =18 ) were treated with NS-DHP in addition to sepsis bundle therapy.HA330 hemoperfusion device were used in each patient of group D.The procedure of hemoparfusion lasted 2.5 hours and carried out trice a 24 hours.Clinical data including APCHE Ⅱ score,PO2/FiO2 (OI),mean arterial pressure (MAP),dopamine usage (DA),plasma level of endotoxin (ET),C-reactive protein (CRP),TNF-α,IL-6 and IL-10 were recorded during the treatment.Results Patients well tolerated NS-DHP without any complication in group D.All patients in both two groups did not receive long-term renal replacement therapy.At 24 h,48 h and 72 h after the initiation of treatment,APACHE Ⅱ score,O1,MAP,DA,ET,CRP,TNF-α and IL-6 improved obviously both groups (P ＜0.05),but there was no significant ditterence in serum levels of IL-10 in both groups.In the group D,APCHE Ⅱ score,OI,MAP,DA,CRP,TNF-α and IL-6 were improved more obviously than those in the group C (P ＜0.05) ).There was no significant difference in plasma levels of ET in both groups during the treatment.Conclusions NS-DHP can improve APACHE Ⅱ score,PO2/FiO2 and MAP in patients with septic shock caused by gram-negative bacteria infection and reduce the levels of CRP,TNF-α and IL-6,but has no effect on the levels of ET and IL-10 as well as on 28-day mortality and ICU stay.

Objective To explore a better method to diagnose the brachial plexus injury as pre-or post-ganglionic,which is quick,simple,quantitative,cheap and accurate.Methods Forty-five SD rats were divided randomly ino pre-or post-ganglionic brachial plexus injury models group,and the choline acetyl- transferase(CHAT)activity was detected by using the radioisotope after different days.Results The ChAT activity of two groups both fall day by day:in the pre-agnglionic group,it falls quickly,and reach 1/10 of nor- mal(675?258)cpm;in the post-ganglionic group,it falls slowly,and reach 1/2 of normal even after 90 days (4906?1119)cpm.Conclusion Intra-operative measure of ChAT can be used to differentiate pre-or post- ganglionic brachial plexus injury.

Objective To study the relationship between urinary albumin excretion rate(UAER)and cardiac structure and function in type 2 diabetes mellitus(T2DM).Methods Five hundred and twenty patients with T2DM were divided into three groups by 8 h UAER:normoalbuminuria group(424 cases),microalbuminuria group(75 cases)and macroalbuminuria group(21 cases).At the same time,50 healthy people were selected as control group.The cardiac structure and function in four groups were evaluated by echocardiographic measurements.Results Left atrial dimensio[(34.39±3.46)mm],left ventricular posterior wall thickness[(10.34±1.05)mm],relative wall thickness(0.46±0.05),interventricular septal thickness[(10.49±1.07)mm],left ventricular mass[(167.37±32.12)g],left ventricular mass index[(87.62±12.16)g/m2]in macroalbuminuria group were significantly higher than those in control group[(32.59±2.71)mm,(9.30±0.77)mm,0.42±0.04,(9.75±0.81)mm,(147.33±27.23)g,(80.14±13.81)g/m2](P＜0.05),mean while the ratio of E/A(0.82±0.19)in macroalbuminuria group was significantly lower than that in control group(1.21±0.16)(P＜0.05).Conclusions In T2DM patients with albuminuria,the cardiac structure and function have changed.With the increase of UAER,the impairments are more prominent.And it may predict diabetes cardiomyopathy.

OBJECTIVETo systematically evaluate prostate health index (PHI) in predicting the results of prostate biopsy in the diagnosis of prostate cancer.

METHODSWe retrieved the literature relevant to the value of PHI in predicting prostate cancer at prostate biopsy published from the inception to February 2014 in the databanks of PubMed (1966 - 2014), CNKI (1982 - 2014), VIP (1989 - 2014), and Cochrane Library (1999 - 2014). According to the inclusion and exclusion criteria and retrieval strategies, we extracted the data, evaluated the quality of the included literature, and performed meta-analysis using the Meta-Disc 1.4 software.

RESULTSTotally, 64 articles were identified, of which 52 were excluded and 12 included with 1 430 cases of prostate cancer and 2 159 normal or BPH controls. There was heterogeneity among the included studies. Based on the random effect model, in predicting the results of prostate biopsy in the diagnosis of prostate cancer, serum PHI exhibited a pooled sensitivity of 55.1% (95% CI: 0.525 - 0.577), a pooled specificity of 71.5% (95% CI: 0.695 - 0.734), a positive likelihood ratio (P-LR) of 2.379 (95% CI: 1.922 - 2.943), a negative likelihood ratio (N-LR) of 0.515 (95% CI: 0.428 - 0.619), a diagnosis odds ratio (DOR) of 5.268 (95% CI: 3.870 - 7.170), a summary receiver operating characteristic curve--area under the curve (SROC AUC) of 0.7578, and a Q * index of 0.6999.

CONCLUSIONSerum PHI plays a role of auxiliary diagnosis in detecting prostate cancer and can be used in the prediction of the results of prostate biopsy.

Objective To explore the role of Color Doppler Flowing Imaging(CDFI) in assessing metastatic lymph node for nasopharyngeal carcinoma (NPC). Methods Neck lymph node were detected by CDFI in 206 patients who received the initial course radiotherapy in our hospital. The characteristic of neck node, such as position, figure, number, size, its relation to surrounding soft tissue, the ratio of longitudinal diameter over trnsverses′(L/T) and blood flow resistance index (RI), were recorded detailedly. Fine needle aspiration biopsy was performed on some of patients under the guide of ultrasound. Results The clinical N-stage was changed markedly after CDFI plus biopsy, with up-staging in 25 from N0 to N1 , 6 N0 to N2, 20 N1 to N2, 3 N1 to N3, 4 N2 to N3; and down-staging in 14 from N2 to N1, 7 from N3 to N2. The misdiagnosis rate of node involvement by palpation was 38.3% (79/206). The sizes of lymph node detected by palpation were larger than those by CDFI (P0.6, and the value would reached to 92.9%(182/196) and 95.5%(107/112)when such criteria combined with the diameter and growth behavior of lymph node. Conclusion Color Doppler Flowing Imaging is useful in N-staging for nasopharyngeal carcinoma by providing more reliable evidence.
