Objective To evaluate the application effect of teaching-picture archiving and communication system (T-PACS) in training image reading ability of eight-year-program students. Methods Sixty students were divided into two groups: control group (applying traditional teaching method) and experimental group (applying traditional teaching method and T-PACS) when doing clinical medical image reading ability training. Making multimedia teaching movie, clinical image reading teaching and establishing image database by T-PACS were used in experiment group. Mean-while, reading room was set up and classroom teaching and problem-oriented assignments were in-creased. Finally objective evaluation of image recognition ability and questionnaire were used to compare the teaching effect. Measurement data were expressed as x±s. Total scores of image reading were am-alyzed by t test. Full score rates were analyzed by X2 test. Results The results showed that the score of medical image reading ability was higher in experimental group (90.08±4.52) than in control group (86.92±4.68) (P=0.010). There were differences in respiratory and orthopedic full score rate (P=0.006;P=0.035). Most students thought that application of T-PACS could effectively improve the teaching and learning quality. Conclusions Application of T-PACS can improve the medical image reading ability of eight-year-program medical students and is worth further promoting.

Objective To investigate the prevalence of depression among the patients with diabetic foot and analyze the influence factors. Methods One hundred and ten patients with diabetic foot were inquired and assessed with patient health questionnaire for self-administered measurement (PHQ-9), meanwhile, the demo-graphic data, metabolic data and diabetes behaviors were also investigated. Results Prevalence of depression was 47.3%. Logistic regression analysis showed that alternation of diarrhea and astriction (OR = 6.901, P =0.017) and formication (OR = 23.401, P = 0.009) were risk factors, and medical insurance (OR = 0.217, P =0.007) was a protective factor. Conclusions Depression is a frequent mental disorder in patients with diabet-ic foot and its influence factors include alternation of diarrhea and astriction , formication and medical insur-ance .

Inflammation is one of the key pathological process of atherosclerosis (AS),and multiple risk factors of AS have consanguineous relationships with the regulation of inflammatory signal pathway.So it could be effective approach to control inflammation,even the pathological process of AS if we do the deep research on AS inflammatory signal pathway and make out the potential medicine.

Objective:To explore the changes of neuron-specific enolase (NSE) and S-100β protein (S-100β) during perioperative period in infants undergoing living liver transplantation and examine the effect of brain injury.Methods:From January 2015 to January 2016 in Department of Anesthesiology First Central Clinical College Tianjin Medical University, study group was composed of forty infants of congenital biliary atresia with an age range of (4-12) months, a body weight of (4-10) kg and American Society of Anesthesiologists (ASA) class Ⅲ/Ⅳ. Another 40 infants undergoing general surgery were selected as control group. In study group, blood samples were harvested from central vein pre-operation (T0), before skin incision (T1), 30 min after anhepatic phase (T2), 1 h of neohepatic phase (T3) and 24h after hepato-reperfusion (T4). In control group, blood samples were collected at pre-operation (T0) and 24 h post-operation (T4). Serum levels of S-100β, NSE, heart rate (HR), mean arterial blood pressure (MAP), central venous pressure (CVP) and bispectral index (BIS) were monitored at T1-4 and end of surgery. All children were assessed by Bayley Scale of Infant Development (BSID) at Day 1 pre-operation and 2/4 weeks post-operation for observing mental and motor development status. The results were described with mental development index (MDI) and psychomotor development index (PDI). Pediatric anesthesia emergence delirium (PAED) was employed for evaluating the severity of delirium during the recovery stage at 30 min and 2/4h post-extubation.Results:In study group, serum levels of S-100β and NSE changed significantly during non-hepatic and neohepatic reperfusion phases. After inferior vena cava occlusion, serum concentrations of S-100β and NSE spiked ( P<0.05) and gradually recovered during neohepatic reperfusion period ( P<0.05). No significant inter-group difference existed in serum S-100β or NSE at T4 ( P>0.05). In study group, as compared with Day 1 pre-operation, MDI/PDI decreased at Week 2 post-operation ( P<0.05) and increased from Month 1 post-operation ( P<0.05). Both MDI and PDI were lower than control group before and at Week 2 post-operation ( P<0.05). MDI/PDI of study group basically reached the preoperative level at Month 1 post-operation ( P<0.05). In control group, no significant difference existed in MDI/PDI at Day 1 pre-operation and Week 2/4 post-operation ( P>0.05). In study group, the delirium rate was up to 30% post-extubation and decreased at 2/4h post-extubation. In control group, the incidence of delirium was low at 30 min and 2/4h post-extubation ( P<0.05). Conclusions:Perioperative evaluations of serum levels of NSE and S-100β are significant for predicting the postoperative onsets of delirium and cognitive impairment in children with living donor liver transplantation.

objective To investigate the tissue localization of CD4+T cells producing IL-17,namely Th17 cells.in patients with systemic lupus erythematosus (SLE),as well as its relationship with the activity of lupus.Methods By using H&E staining.double-label immunofluorescence.immunohistochemistry and confocal microscopy.the localization of Th17 cells was carried out in peripheral blood mononuclear cells (PBMCs).affected tissue of skin and lung obtained from 4 patients with active SLE and 2 normal human controls.Flow cytometry.reverse transcription PCR.ELISA were used to detect the proportion of Th17 cells in PBMCs,the mRNA expression of interleukin-17(IL-17)A and IL-17 F,and serum level of interleukin 17,respectively,in 50 consecutive adult patients with SLE and 15 normal human controls.Results Th17 cells were detected in PBMCs of patients with active SLE.and the fuorescence intensity of IL-17 was significantly higher in patients with active SLE than in normal human controls(127.6±20.5 vs 40.6±11.1,P＜0.001).Infiltrates of Th17 cells were noted in both skin and lung tissues of patients with active SLE.but not in those of normal human controls.The proportion of Th17 cells in PBMCs was increased in patients with active SLE.and the proportion positively correlated with SLE disease activity index(SLEDAI) (r=0.725,P＜0.01).Further more.a significant increase was observed in the mRNA expression of IL-17 A and IL-17 F and serum level of IL-17 in patients with active SLE compared with normal human controls.The amount of Th17 cells was positively correlated with the development of vasculitis.and it experienced a decrease with the remission of SLE.Conclusions A proliferation of Th17 cells is noted in patients with active SLE.which seems to closely correlated with the activity of SLE and may take part in the development of vasculitis in SLE.

OBJECTIVETo investigate the effect of noise on the antioxidant capacity in different regions of brain tissue in guinea pigs.

METHODSThirty male white red-eye guinea pigs were equally and randomly divided into five groups: 1-, 3-, 7-, and 14-day groups after noise exposure and control group. The guinea pigs of the experimental groups were exposed to steady white noise with a sound pressure level at 100 dB for 8 h per day and for 2 consecutive days. The auditory brainstem response (ABR) of guinea pigs, as well as the glutathione (GSH) level, methane dicarboxylic aldehyde (MDA) level, and superoxide dismutase (SOD) activity in the cerebrum, cerebellum, and hippocampus, was determined prior to and 1, 3, 7, and 14 days after noise exposure.

RESULTSAfter noise exposure, the shifts in ABR threshold of the experimental groups were significantly higher than that of the control group (P<0.05). Compared with those in the control group, the SOD activity and GSH level both significantly decreased in the cerebrum tissue of each experimental group after noise exposure (P<0.05) and MDA content significantly increased in the 1-day group (P<0.05). As for cerebellum tissue, the SOD activity and GSH level in the 7-day group were significantly lower than those in the control group (P<0.05), but there was no difference in MDA level between each experimental group and the control group (P>0.05). In comparison with those in the control group, the GSH and MDA levels in the 1-day group after noise exposure were significantly higher, and the GSH and MDA levels in the 3-day group and the MDA level in the 7-day group after noise exposure were significantly lower (all P<0.05).

CONCLUSIONNoise exposure can lead to hearing loss and affect the antioxidant capacity of brain tissue, which indicates that the improvement in antioxidant levels may alleviate noise-induced damage.

Type B aortic dissection is a life-threatening aortic disease.With the development of clinical classification and diagnostic method,the mortality of type B aortic dissection has been greatly decreased.In respect of treatment,endovascular repair due to minimally invasive advantages become the first choice for the treatment of complicated type B aortic dissection.For non-complicated type B aortic dissection,endovascular repair also gradually replace drug treatment,and showed good efficacy.Open surgery is only available for patients who ate not suitable for endovascular repair or repair failure or patients with connective tissue disease.

A rapid and sensitive method based on ultrafast liquid chromatography-tandem mass spectrometry was developed and validated for simultaneous determination of Sudan Ⅰ, Sudan Ⅱ, Sudan Ⅲ, and Sudan Ⅳ levels in rat whole blood. Cleanert C18 mixed-mode polymeric sorbent was used for effective solid-phase extraction cleanup. Separation was carried out on a reversed-phase C18 column (100 mm × 2.1 mm, 1.8 μm) using 0.1% (v/v) formic acid in water/0.1% (v/v) formic acid in acetonitrile as the mobile phase in gradient elution. Quantification was performed by an electrospray ionization source in the positive multiple reaction monitoring mode using D5-Sudan I as the internal standard. Calibration curves showed good linearity between 0.2 and 20.0 μg/L, with correlation coefficients higher than 0.9990. The average recovery rates were between 93.05% and 114.98%. The intra- and inter-day relative standard deviations were within 6.2%. The lower limit of quantification was 0.2 μg/L. All the analytes were found to be stable in aseries of stability studies. The proposed method was successfully applied to a pharmacokinetic study of four Sudan dyes after oral administration to rats.
