Methods 74 patients with clear diagnosis non-digestive diseases which initial symptom was acute abdominal pain were analyzed. Results The most common causes of misdiagnosis were blood system diseases,circulatory diseases,metabolic diseases,endocrine system diseases,respiratory diseases,nervous system disease,accounting for 35.1% ,25.7% ,10. 8% ,8. 1% ,6. 8% ,6. 8%.The rest,such as the urinary system diseases,toxic diseases were not rare. Conclusion Non-digestive diseases which initial symptom was acute abdominal pain could be caused by the body's various systems,and the causes were complex,the diseases conditions were critical and changed rapidly,so it was difficult to diagnose and had to be Paid attention on.

Mild stroke refers to ischemic stroke with mild neurological defects.In recent years,its incidence rate has increased gradually.However,there is no standardized definition for mild stroke,and there is a great controversy about whether to conduct thrombolytic therapy for mild stroke.The conventional wisdom holds that the patients with mild stroke should not be treated with intravenous thrombolysis;however,many studies have indicated that the short-term and medium-term outcomes are poor in patients with mild stroke without receiving thrombolytic therapy,and many patients with mild stroke may benefit from thrombolytic therapy.This article summarizes about the definition of mild stroke and the clinical studies of thrombolytic therapy in recent years,hoping to provide reference for clinicians in order to make better clinical decisions.

Hematoma growth is an independent risk factor for the prognosis of htracerebral hemorrhage.It is very common in the acute stage of intracerebral hemorrhage.There are many uncertainties about the definition,mechanisms,and influential factors of hematoma growth,and the effective therapy is lacking,therefore,early prevention and identification are critical.

Objective To observe the characterization of fat emboli in cardiac chamber in pig model and the patients undergoing total hip arthroplasty(THA) by transesophageal echocardiography(TEE). Methods Different dose of fatty liquid was injected slowly via the internal jugular vein. The changes of the image were observed by continuous TEE. The lethal dose of fat embolism was recorded. Twenty-two patients underwent TEE during THA. Gray scale and echo intensity of fat embolism in right atrium were studied quantitatively in varied periods of the operation. Results With the increase of fat liquid injected in pig model, the strong- echo particles in right atrium and ventricle became more and more, the imaging of the particles was from “moving star”, “shower-like” to “snow fluffy”, at last paradoxical fat embolism occurred when the dose of fat liquid was over 4 ml. The accumulated lethal dose of fat embolism was 15.8 ～ 27.8 ml.②Fat emboli appeared as strong- echo particles in right atrium were found in different period of THA. Average gray scale and echo intensity of emboli in right atrium were significantly higher in period B than in other periods during THA. Conclusions Fat emboli in cardiac chamber can be found sensitively by TEE. Intra-operative monitoring and quantitative analysis is helpful to identifying fat embolism syndrome.Paradoxical embolism is a reliable evidence of fat embolism syndrome.

Objective To analyze the correlation between anterior circulation artery stenosis and lacune or lacunar infarct(LI) in elderly patients.Methods A retrospective analysis of data was performed in 111 patients with intracranial artery atherosclerosis,ischemic cerebral infarction or transient ischemic attack from January to December 2016 in our hospital.All the patients underwent non-contrast brain MRI or CT scan,as well as one-stop dynamic whole brain 4D CT angiography and CT perfusion scan(CTA-CTP/ perfusion).Imaging data were retrospectively analyzed.Intracranial 4D CTA was produced by using MIP and CPR post processing.The correlation of intracranial internal carotid artery(ICA)and middle cerebral artery (MCA)stenosis with lacunar infarct or lacune was analyzed by chi-square test using IBM SPSS Statistics 22.0 software.Results The average age of 111 patients was(68.4± 6.8)years.A total of 19 phases with 6080 images were obtained by one-stop scanning.The optimal phase of artery visualization was selected from 19 phases for evaluating artery stenosis.Intracranial ICA and/or MCA stenosis were revealed in 94 patients,including 73(65.8％)patients with LI or lacune and 21 patients(18.9％)without LI or lacune.17 patients without intracranial ICA or anterior circulation of MCA stenosis included 7 patients(6.3 ％)with LI or lacune and 10 patients(9.0％)without LI or lacune.Anterior circulation vessels stenosis was positively correlated with lacunar infarction or lacune(x2 =7.794,P=0.005).94 patients with anterior circulation vessels stenosis were further divided into 2 subgroups:unilateral and bilateral stenosis.39 cases showed unilateral vessels stenosis,including 25 cases (26.6 ％) with LI or lacunein,and 14 cases (14.9 ％) without LI or lacunein.And 55 cases showed bilateral vessel stenosis,including 48 cases (51.1％)with LI or lacune,and 7 case (7.4 ％) without LI or lacune.The risk for LI or lacunein was statistically higher in bilateral vessel stenosis than in unilateral vessel stenosis(x2 =7.061,P=0.008).Patients with anterior circulation vessels stenosis combined with LI or lacune were 73 cases,including 31 cases of grade Ⅰ,19 cases of grade Ⅱ,14 cases of grade Ⅲ,and 9 cases of grade Ⅳaccording to Trial criteria(NASCET)classification,with no significant difference between the different grades of anterior circulation vessels stenosis.Conclusions A correlation between ICA or MCA stenosis and lacunar infarction or lacune may exist.Risk for lacunar infarction or lacune is higher in patients with bilateral artery stenosis than in patients with unilateral artery stenosis.

Objective To investigate the effect of hyperacute intensive antihypertensive treatment on the prognosis of intracerebral hemorrhage in basal ganglia region. Methods From January 2013 to December 2015,100 patients with intracerebral hematoma in basal ganglia region (onset ≤3 h)at the Neurological Intensive Care Unit,the First Affiliated Hospital of Dalian Medical University were enrolled prospectively. They all randomly received the intensive antihypertensive or standard antihypertensive treatment voluntarily. They were divided into either an intensive antihypertensive group or a standard antihypertensive group according to the random number table (n = 50 in each group). Within 1 h after beginning to treatment,the target systolic blood pressure was controlled in 130 -140 mmHg in the intensive antihypertensive group,the target systolic blood pressure was controlled in 160 -180 mmHg in the standard antihypertensive group,and the target systolic blood pressure was maintained respectively in the following 7 d. Head CT was performed gain at 24 h after treatment. The intracranial hematoma expansion was evaluated. The National Institutes of Health Stroke Scale (NIHSS)and the modified Rankin scale (mRS)were used to
evaluate their prognoses. The differences of the cumulative mortality in both groups were compared at the same time. Results The incidences of hematoma expansion of the intensive antihypertensive group and the standard antihypertensive group were 12. 0% (6/ 50)and 30. 0% (15/ 50)respectively. There was significant difference between the 2 groups (χ2 = 4. 882,P = 0. 027). There were no significant differences in NIHSS scores within or between both groups at each time points (all P > 0. 05). They were followed up for 90 d,no adverse events occurred in both groups. The favorable prognosis rates of the neurological function were 36. 0% (18 / 50)and 18. 0% (9 / 50)respectively in the intensive antihypertensive group and the standard antihypertensive group. There was significant difference between the 2 groups (χ2 = 0. 411,P =0. 043). Kaplan-Meier curves showed that the cumulative mortality at 24 h,within 7 d and 90 d in the intensive antihypertensive group and the standard antihypertensive group were 4. 0% (2 / 50),6. 0%(3 / 50),and 10. 0% (5 / 50),respectively,those of the standard antihypertensive group were 10. 0%(5 / 50),24. 0%(12 / 50),and 30. 0%(15 / 50),respectively. The results of Log-rank test found that there was significant difference in cumulative mortality between the 2 groups (χ2 =6.280,P =0.012). Conclusions The intensive antihypertensive treatment in the hyperacute cerebral hemorrhage is safe and feasible in basal ganglia region. It contributes to improve prognosis of neurological function,and reduce the incidence of hematoma expansion and the 90 d cumulative mortality.

Objective To explore the correlation between food allergies and duodenal mast cells in pathogenesis with functional dyspepsia (FD).Methods The symptoms of FD were scored in 48 patients with FD,which included 23 patients with postprandial distress syndrome (PDS) and 25 patients with epigastric pain syndrome (EPS).The specimens of duodenal and descending part of duodenum mucosa were obtained under gastroscopy in 48 FD patients and 21 healthy volunteers,and 3 mL venous blood was taken at same time.The percentages of mast cells and degranulated mast cells were calculated after the specimens were stained by toluidine blue.The serum specific IgG antibodies of 14 food allergies were detected by enzyme-linked immunosorbent assay.Two-sample comparison was performed by t test,LSD-t-test for groups' comparison,chi-square or Fisher’s exact test for rates comparison and Pearson linear correlation for correlation analysis.Results The number of mast cells in duodenal and descending part of duodenum of FD group,PDS group and EPS group was significantly higher than that of control group and the differences were statistically significant (duodenal:t =3.387,3.536 and 3.510; descending part of duodenum:t=5.810,4.400 and 3.813; all P＜0.01).In duodenal and descending part of duodenum,the percentages of degranulated mast cells in all mast cells of FD [(60.23± 5.10)％ and (66.97±5.30)％],PDS [(59.84±4.50)％ and (66.63±5.37) ％] and EPS [(60.58±5.66) ％ and (67.28±5.32) ％] were all higher than those of control group [(25.38 ± 2.32％) and (30.66 ±2.89)％],and the differences were statistically significant (duodenal:t=33.639,25.496 and 26.563; descending part of duodenum:t=32.513,30.521 and 31.612; all P＜0.05).There was no correlation between the number of mast cells,percentage of degranulated mast cells in duodenal or descending part of duodenum and the scores of symptoms (all P＞0.05).In PDS group,the rates of positive specific IgG antibodies of beef,crab,shrimp,wheat and chicken were significantly higher than those of control group,and the differences were statistically significant (beef x2=12.108,crab x2=17.771,shrimp x2=6.832 and wheat x2=4.375,chicken (Fisher’s exact test); all P＜0.05).In EPS group,the rates of positive specific IgG antibodies of beef,soy and chicken were significantly higher than those of control group,and the differences were statistically significant (beef x2 =8.915,soy x2 =18.600,chicken (Fisher' s exact test) ; all P ＜0.01).The scores of positive specific IgG antibodies of food allergies and types of FD,PDS and EPS were significantly higher than those of control group,and the differences were statistically significant (the score of positive IgG:t=14.988,4.062 and 3.693; the positive type of IgG:t=8.805,4.177 and 3.388; all P＜0.01).The scores of positive specific IgG antibodies of food allergies and types were positively correlated with the number of mast cells and the percentage of degranulated mast cells in duodenal part of duodenum (the score of positive IgG:r=0.247 and 0.307,the positive type of IgG:r=0.243 and 0.326; all P＜0.05).Conclusion The specific IgG antibody of food allergies might play a role in the pathogenesis of FD through inducing an increase in the number of mast cells and the percentage of degranulated mast cells in duodenal mucosa.

OBJECTIVE: To evaluate the short-term efficacy and investigate the factors of specific immunotherapy (SIT) efficacy of allergic rhinitis. METHOD: Fifty-seven patients with allergic rhinitis to dermatophagoides pteronysinus were included to receive SIT. Pair t-test was used to compare the symptom scores, visual analogue scores (VAS) and medication scores in patients before SIT and into maintain treatment statement to evaluate the clinical efficacy. T-test and Spearman correlation analysis were used to analyze the correlation between gender, age,reaction condition of skin prick test (SPT) and serum sIgE and the efficacy of SIT. RESULT: SIT was able to significantly reduce the symptom scores, VAS and medication scores. But the correlation between gender, age, SPT, and sIgE and theefficacy of SIT were not significant. CONCLUSION SIT is effective in the short-term treatment of AR. Further research is needed to investigate the factors that impact the efficacy of SIT.

Objective To investigate the influence of simvastatin treatment on Toll-like receptor 4 (TLR4) in monocytes of peripheral blood in patients with sepsis and severe sepsis and its significance. Methods A prospective randomized controlled trial was conducted. 106 patients with sepsis and 92 patients with severe sepsis admitted to Department of Critical Care Medicine of Henan Provincial People's Hospital from August 2013 to June 2015 were enrolled. These two groups of patients were randomized into conventional treatment group and simvastatin group. All patients received treatment according to the 2012 International Sepsis Treatment Guidelines, including anti-infection drugs, nutritional support, and palliative treatment, and the patients with severe sepsis were given early goal-directed therapy (EGDT). The patients in simvastatin group received simvastatin 40 mg daily orally for at least 15 days. The peripheral blood was collected and the monocytes were isolated at 1, 5, 10, 15 days after intensive care unit (ICU) admission. TLR4 expression on the surface of TLR4/CD14+ double positive monocytes was determined by flow cytometry, and adverse reaction was observed during treatment. Results TLR4 expression on the surface of monocytes showed a tendency of decreasing with prolongation of simvastatin treatment in the simvastatin group in patients with sepsis (n = 59) or severe sepsis (n = 54). However, in patients with sepsis, TLR4 level was significantly decreased from 10 days in simvastatin group as compared with that of conventional therapy group (n = 47), and it was decreased up to 15 days [mean fluorescence intensity (MFI): 21 (19, 28) vs. 27 (25, 33) at 10 days, Z = 2.198, P = 0.021; 16 (15, 21) vs. 26 (23, 34) at 15 days, Z = 4.611, P = 0.002]. In patients with severe sepsis, there was no significant difference in TLR4 level at different time points between simvastatin group and conventional treatment group (n = 38) [MFI: 55 (52, 63) vs. 56 (48, 65) at 1 day, Z = 0.313, P = 0.692; 47 (42, 56) vs. 49 (41, 58) at 5 days, Z = 0.827, P = 0.533; 40 (35, 42) vs. 42 (37, 45) at 10 days, Z = 1.012, P = 0.301; 33 (30, 38) vs. 38 (35, 41) at 15 days, Z = 0.539, P = 0.571]. No adverse reaction related with simvastatin was found during treatment in patients with sepsis or severe sepsis. Conclusions Statins could significantly down-regulate the TLR4 expression on peripheral blood monocytes in septic patients, while it showed no significant influence on TLR4 expression in patients with severe sepsis. A different effect of statins on TLR4 expression and the downstream inflammation process in sepsis and severe sepsis patients might partially explain the discrepancy in previous reports about the therapeutic effect of statins therapy in sepsis and severe sepsis patients.
