Objective:To investigate the characteristics of implicit memory and its related factors in schizophrenic patients with negative and positive symptoms.Methods:Ninety-three schizophrenic patients (including 52 cases of negative symptoms group and 41 cases of positive symptoms group) and 30 normal controls (normal group) were tested with the method of Chinese character word completion method. The reaction time and correct rate were recorded and compared with analysis of variance and t-test, and the correlation with demographic factors was analyzed with Pearson correlation analysis. Results:Accuracy of implicit memory test in schizophrenia group: there were statistically significant differences in the accuracy of patients with different course of disease (≤5 years: (38±5)%, 5-15 years: (34±8)%, ≥15 years: (34±7)%, P<0.05).The differences were statistically significant in the accuracy of patients with different education levels(primary school: (35±6)%, junior and senior high school: (34±7)%, secondary college education and above: (39±5)%, P<0.05).The accuracy of patients with education years < 10 years ((34±7)%) was significantly lower than those with education years ≥10 years ((37±6)%, P<0.05).Reaction time results of implicit memory test in schizophrenia group : there were significant differences in reaction time of patients with different disease course(≤5 years: (3 248±971)ms, 5-15 years: (3 515±672)ms, ≥15 years: (3 925±842)ms, P<0.05).The differences were statistically significant in the reaction time of workers ((3 495±712)ms), farmers ((3 870±878)ms) and soldiers ((3 024±924)ms, P<0.05).The reaction time of patients with clozapine ((3 869±871)ms) was significantly higher than that of patients with olanzapine ((3 393±626)ms, P<0.05).Intergroup results of accuracy: the accuracy of normal control group ((40±5)%) was significantly higher than that of negative symptom group ((33±7)%, P<0.01).The accuracy of negative symptom group was significantly lower than that of positive symptom group ((37±6)%, P<0.01).Intergroup reaction time results: the reaction time of normal control group ((2 660±667)ms) was significantly lower than that of negative symptom group ((3 678±951)ms, P<0.01) and positive symptom group ((3 072±865)ms, P<0.05).The reaction time of negative symptom group ((3 678±951)ms)was significantly higher than that of positive symptom group( P<0.01).There was significant negative correlation between the accuracy of implicit memory and the course of disease in schizophrenia ( r=-0.22, P<0.05). Conclusion:The implicit memory of schizophrenic patients is related to the course of disease, taking drugs, and occupation.There may have differences in implicit memory between patients with negative and positive symptoms of schizophrenia.

Objective: To detect the characteristics of phosphatase and tensin homolog (PTEN) mutations in adult T-cell acute lymphoblastic leukemia (T-ALL) and its relationship with the prognosis. Methods: Fifty-five adult T-ALL patients were enrolled in Jiangsu Province Hospital from February 2010 to April 2016. Mononuclear bone marrow cells were extracted by using Ficoll density gradient centrifugation. Genomic DNA was extracted from isolated mononuclear cells. Amplified exon 1-9 of PTEN by polymerase chain reaction (PCR) specifically amplified PTEN exon, then DNA was purified, sequenced and compared. The mutation occurrence rate, mutation types, and the relations with several clinical indicators were analyzed. Results: PTEN mutations were detected in 5 patients, and 8 types of mutations were detected in 55 T-ALL patients with mutation rate of 9.1% (5/55). All the mutations were located in exon 7 of the genes. Five patients with PTEN mutations also merged other gene mutations like NOTCH1 and DNM2. The level of median lactate dehydrogenase (LDH) in patients with PTEN mutations was higher than that in patients without PTEN mutations (3 358 U/L vs. 755 U/L, Z=-2.014, P= 0.044). No significant differences were found in gender, age, white blood count, hemoglobin, platelet count, overall survival rate, event free survival, recurrence free survival between the two groups (P > 0.05). Conclusion PTEN is a tumor suppressor gene, and its mutation plays a significant role in the occurrence and development of adult T-ALL patients, which may be associated with the poor prognosis.

Objective To investigate the characteristics of peroperative blood pressure and heart rate in patients with normotensive incidental pheochromocytomas in order to provide the basis for peroperative treatment. Methods This retrospective study collected the data of 104 patients with a pathological diagnosis of unilateral pheochromocytoma at PLA General Hospital during January 2011 to December 2016. They were divided into normotensive incidental pheochromocytomas(NIP) group (n＝50) if the patients were normotensive and HIP group ( n＝54) if the patients were with hypertension. The clinical features, imaging features and peroperative hemodynamics were analyzed. Results ( 1) The age, urinary norepinephrine, daily dosage and duration of phenoxybenzamine in NIP group were less than those of HIP group (all P<0.05). (2) Preinduction blood pressure, maximum blood pressure, and total fluid intake in NIP group were lower than those in HIP group(all P<0.05). The blood pressure range, heart rate range, increased blood pressure, minimum mean arterial pressure, vasoactive medication were without statistical significance between these two groups. ( 3) The times and rate of intraoperative systolic blood pressure more than 30% baseline, 200 mmHg (1 mmHg＝0.133 kPa), 180 mmHg, 160 mmHg, intraoperative tachycardia, bradycardia, intraoperative hypotension and postoperative hypotension were without statistical significance between these two groups. (4) Stratified analysis of age (50 years), phenoxybenzamine (40 mg/d), tumor diameter (50 mm) and preinduction blood pressure (130/80 mmHg) showed that intraoperative blood pressure and heart rate were without statistical significance between these two groups. ( 5) There was no correlation between phenoxybenzamine ( daily dosage or duration ) and peroperative hypotension. Applying phenoxybenzamine or vasoactive medication was not correlated with peroperative hypotension in NIP group. Conclusion The peroperative blood pressure and heart rate of patients with NIP are similar to those of patients with HIP. Adequate peroperative treatment should be applied to NIP to avoid hemodynamic instability.

OBJECTIVETo develop a quartz crystal microbalance (QCM) immunosensor with high sensitivity and selectivity for the rapid detection of diethylstilbestrol.

METHODSDextran was used as reducing agent for preparing gold nanoparticles (AuNPs) with the size of 40 nm. The AuNPs were coupled with anti-DES antibody after amination. A monolayer was generated after immersing the quartz crystal into the solution of 5 mmol/L 11-mercaptoundecanoic acid(MUA) for 16 hours. After the monolayer was activated by 1-ethyl-3-(3-dimethylaminopropry) carbodiimide hydrochloride (EDC·HCl) and N-hydrosuccinimide (NHS), 20 μl of 2.2 mg/ml DES-HS-BSA was dropped onto the surface of crystal to prepare a sensitive membrane which can recognize DES specifically. Then, 50 μl of 1 mol/L ethanolamine (pH 8.5) was used to seal the carboxylic groups to make the sensitive membrane which could identify DES specifically. QCM immunosensor was used as detection platform to optimize the reaction conditions. Under the optimized conditions, 10 μl of 28 μg/ml AuNPs-antibody was mixed with 10 μl of 0.03-2.5 μg/ml DES, and the mixture was added on the sensitive membrane. QCM immunosensor was used to detect the signals and the standard curve was obtained at the same time. The detection limit was calculated based on the standard curve. The specificity was evaluated by testing DES and its analogues with the same concentration.

RESULTSThe optimized concentration for the immobilization of DES-HS-BSA on the surface of QCM was 2.2 mg/ml. The optimized concentration for coupling anti-DES antibody with AuNPs was 7 μg/ml and 15 nmol/L, respectively. The optimized concentration of AuNPs-antibody was 14 μg/ml. The logarithm of DES concentration was proportional to the frequency shift in the range of 0.16-500 ng/ml, Δf=-24.170 lgCDES+69.71, R(2)=0.998. The detection limit of this method was 0.13 ng/ml. DES analogues could not influence the detection of DES obviously, so the sensor had good specificity.

CONCLUSIONThe quartz crystal microbalance immunosensor with gold nanoparticals amplification could detect DES sensitively and rapidly.
