Objective To explore the preventive role of low molecular weight heparin in progressive ischemic stroke.Methods 203 patients with cerebral infarction within 72 hours of the onset were randomly divided into low molecular weight heparin(LMWH) group and routine treatment group.LMWH group was administered subcutaneously twice daily for 5~10 days with 0.4 mL LMWH on the basis of routine treatment. The activities of plasminogen and coagulation factor Ⅹ and the indexes of hemorrheology were measured before and after the treatment, the neurologic function deficits of patients with progressive ischemic stroke were evaluated.Results 11 cases for progressive ischemic stroke were occurred in LMWH group, 23 cases in routine treatment group for progressive ischemic stroke, there was remarkable difference between the two groups( P

Objective To investigate the effects of preoperative selective gastric arterial chemoembolization on the tumor vasculature in patients with gastric carcinoma.Methods 40 patients with gastric cancer were divided into two groups :(1)gastric arterial influsion(GAI)group;and (2)gastric arterial chemoembolization(GAE)group.The peripheral vein plasma tumor necrosis factor(TNF ?) and thrombomodulin(TM)were determined before radiologic intervention(RI),and1d,3d after R1;and the gastric vein plasma TNF ? and TM were also determined during operation.The curative surgical resection of gastric cancer was performed between 7 and 10 days after treatment.Stomach histological alterations were observed postoperatively.Results Compared with GAI group ,the plasma TNF ? levels increased markedly at all the time points,and gastric vein plasma TM levels decreased siginificantly in GAE group (P

Objective To study the diagnostic value of common inflammatory markers in patients with infectious diseases. Methods One hundred sepsis patients, 100 viral infection patients,100 pulmonary tuberculosis patients and 100 gonorrhea patients were analyzed retrospectively. The contents of procalcitonin (PCT), C-reactive protein (CRP), haptoglobin (HP), ceruloplasmin (CER), α1-acid glycoprotein (α1-AAG), α1-antitrypsin (α1-AAT), white blood cell count (WBC) and erythrocyte sedimetation rate (ESR) were measured. The receiver operating characteristic curve (ROC curve), sensitivity, specificity, positive predictive value, negative predictive value, Youden's index,positive and negative likelihood ratios and total coincidence rate were calculated respectively. Results The area under the ROC curve, sensitivity, specificity, Youden's index and positive likelihood ratios,positive predictive value and total coincidence rate of PCT in sepsis patients were 0. 895, 0.84, 0.92,0.76, 10.50, 0.91 and 0.88, respectively, which were superior to CRP, HP, CER, α1-AAG, α1-AAT, WBC and ESR. Conclusions PCT is a better inflammatory reactive parameter than other parameters currently applied in practice and may serve as a rapid and sensitive test in the early stage of severe bacterial infections.

OBJECTIVETo analyze the neurolinguistic features of a Chinese patient with pure alexia in acute and convalescent stages.

METHODSWe assessed the reading and writing abilities of the patient with the Aphasia Battery of Chinese (ABC), the reading examination of Chinese characters (1999, Lin) and the Chinese agraphia battery (CAB).

RESULTSIn the ABC examination in the acute phase, the patient performed well in oral expression and comprehension, and the prominent linguistic abnormalities were alexia and merging agraphia; in the convalescent phase, the recovery of alexia was better than that of agraphia. In reading examination of Chinese characters, shape errors were the main reading disorders in the acute phase with a few semantic errors, regularization errors and mistakes in pronunciation, but only shape errors reappeared in the recovery period. CAB examination showed impairment of writing for pictures and dictation abilities in the recovery period but recovery of other writing abilities. The writing disorder was manifested as aphasic agraphia, with obvious dysorthography and lexical errors; the patient was capable of spontaneous writing only after spontaneous speech, and was able to read the written words.

CONCLUSIONThe linguistic components of the Chinese patient with pure alexia showed different patterns of damage and recovery, suggesting the difference in their respective neuropsychological pathways.

Objective:To evaluate the auxiliary diagnosis value of bacterial culture, polymerase chain reaction (PCR) and serum anti-pertussis toxin immunoglobulin G (AntiPT-IgG) level detection in suspected pertussis.Methods:A total of 110 suspected cases of pertussis treated in the Department of Pediatrics of Wuhu No.1 People′s Hospital from June 2018 to May 2019 were recruited for the study.The nasopharyngeal swabs of all cases were collected for Bordetella pertussis culture and specific nucleic acid PCR detection.Serum samples of 78 cases were collected for the detection of AntiPT-IgG level by enzyme linked immunosorbent assays.Results:The positive rates of bacterial culture group and PCR group were 21.8% and 30.0%, respectively, with no statistically significant difference ( χ2=1.198, P>0.05). The culture positive rate of cases with the duration of cough<2 weeks was 32.1%, which was signi-ficantly higher than that of cases with the duration of cough about 2-4 weeks (14.3%) or >4 weeks (9.1%) ( χ2=6.522, P<0.05). The PCR positive rate of cases with the duration of cough <2 weeks was 39.6%, which was also significantly higher than that of cases with the duration of cough about 2-4 weeks (25.7%) or > 4 weeks (13.6%) ( χ2=6.126, P<0.05). The mean value for serum AntiPT-IgG level of 78 cases was (75.727±78.454) IU/mL, the median AntiPT-IgG levels of cases with the duration of cough<2 weeks and about 2-4 weeks were 5.909 IU/mL and 20.948 IU/mL, respectively, and the positive rates were 14.7% and 38.1%, respectively.The AntiPT-IgG level of cases with the duration of cough> 4 weeks and that at convalescent stage were (79.281±68.254) IU/mL and (107.242±75.750) IU/mL, and the positive rates were 39.1% and 57.1%, respectively. Conclusions:In the vaccine era, the results of pathogenic and serological tests should be combined to assist the clinical diagnosis of pertussis.The positive rate of bacterial culture and specific nucleic acid pathogen detection in children with cough duration less than 2 weeks is high, and the serological diagnosis is more effective after the duration of cough is over 4 weeks.
