BACKGROUND: Leukoaraiosis is a group of changes in image. Since the firm pathogenic mechanism on leukoaraiosis has been unknown, the evaluation at the earlier stage of the disease has not been emphasized commonly and there is rather less recognition of the alternations on its electrophysiological system.OBJECTIVE: To probe into the clinical characteristics and alternations on image and evoked potential in simple leukoaraiosis and subcortical arteriosclerotic encephalopathy(Binswanger' s disease) and carry on the comparison with healthy people.DESIGN: Retrospective comparative study based on patients and healthy people.SETTING: Department of neurological internal medicine of one university hospital and department of neurological internal medicine of one railway central hospital.PARTICIPANTS: Outpatients or inpatients with cerebral vascular disorders in Qilu Hospital Affiliated to Shandong University were collected from August 1995 to March 2000. Totally 114 cases were leukoaraiosis, of which, 79 cases were males and 35 cases females. And 41 cases were Binswanger' s disease,of which, 28 cases were males and 13 cases females. Fifty healthy aged people who received routine physical check were randomized from the clinic of the hospital as the control.METHODS: The analysis was carried on the risk factors, clinical characteristics and CT exam in 114 cases of leukoaraiosis and 41 cases of Binswanger' s disease, of which, 74 leukoaraiosis cases and 35 Binswanger' s disease cases had received cranial MRI exam. Of those, 43 cases of simple leukoaraiosis associated with hypertension, 30 cases of Binswanger' s disease and 50 cases in the normal control were selected to carry on the examinations of body-sensory evoked potential, brain stem auditory evoked potential and visual evoked potential.coronary heart disease, diabetes, hyperlipemia, smoke, cerebral apoplexy,evoked potential and visual evoked potential.RESULTS: According to practical management analysis, 114 cases of leukoaraiosis, 41 cases of Binswanger' s disease and 50 cases in the control were diversification, mainly characterized as slightly declining of memory and loss of gait stability. Hypertension is predominated anong risk factors in Binswanger' s disease group (95.1% ), mainly characterized as physical signs of local neural focus, obvious cognitive disturbance and cerebral in CT exam that 70.2% (80/114) of cases presented brain whiter-matter abnormity in type Ⅰ. It was indicated in MRI exam that 72% (53/74) of cases presented brain whiter-matter abnormity, type Ⅰ, 27% (20/74) presented type Ⅱ and 1% (1/74) presented type Ⅲ. For Binswanger's disease patients, it was indicated in MRI exam that 54% (19/35) of cases presented brain white-matter abnormity, type Ⅲ, and 46% (16/35) presented type Ⅳ.Symmetrical extension of bilateral ventricles presented in Binswanger' s disbody-sensory evoked potential was 84% (36/43), of which, the mild abnormity occupied 60% (26/43) and moderate abnormity 23% (10/43); The abnormity rate of brain stem auditory evoked potential was 63% (27/43) and that of visual evoked potential was 54% (23/43). In Binswanger' s disease group, the abnormity rate of body-sensory evoked potential was 97% (29/30),of which, mild abnormity was 7% (2/30), moderate abnormity was 47%(14/30) and severe abnormity was 43% (13/30); The abnormity rate of brain stem auditory evoked potential was 87% (26/30) and that of auditory evoked potential was 83% (25/30).CONCLUSION: The risk factors of simple leukoaraiosis are diversified,without obvious physical signs of local neural focus. The diagnosis of it is mainly depended on abnormity Ⅰ of brain white matter described in images,manifested as remarkable dysfunction of cerebral eletrophysiology. Binswanger' s disease patients are mainly characterized as hypertension, relevantly obvious cognitive disturbance and common seizure of cerebral apoplexy. Abnormity Ⅲ of brain white matter indicated in CT exam, abnormity Ⅲ or Ⅳ of that in MRI exam are the image evidence for diagnosis. Remarkable abnormity also presents in cerabral electrophysiology, in which, abnormal body-sensory evoked potential is especially significant.

Objective To investigate the short?term complications and cosmetic outcomes of radiotherapy in breast conserving surgery for early?stage breast cancer. Methods A retrospective analysis was performed on clinical data from 30 patients with early?stage breast cancer from 2013 to 2015. All patients underwent breast conserving surgery combined with intraoperative low?energy X?ray radiotherapy. The prescribed dose was 20 Gy at the surface of the applicator. Local complications, radiation injury, and cosmetic outcomes were observed after surgery. Results No grade 3?4 adverse reactions were found in patients. In terms of short?term complications, four patients (13%) had seroma, two of whom needed suction treatment;three patients ( 10%) had grade 1?2 skin erythema. Half of the patients had excellent cosmetic outcomes. None of the patients had local recurrence or distant metastasis. Conclusions Intraoperative low?energy X?ray radiotherapy is safe and feasible in breast conserving surgery for breast cancer. It can be considered as an optional approach for tumor bed boost in some patients with early?stage low?risk breast cancer.

Objective To explore the role of long noncoding RNA ( lncRNA) CTD-2012K14. 6 in the development of gestational diabetes mellitus (GDM) related macrosomia. Methods The quantitative real-time PCR ( qRT-PCR) was performed to measure the expression of CTD-2012K14.6 in placentas of women with or without GDM, and the quantity of CTD-2012K14. 6 expression and its association with fetal weights were analyzed; Bioinformatic analysis was performed to predict the downstream molecules. CTD-2012K14. 6 over-expressing lentiviral and siRNA was constructed in human trophoblastic cell line HTR-8/SVneo cells, qRT-PCR and Western blot (WB) were used to invest its effect in modulating the expression of downstream molecules. Results The expression of CTD-2012K14.6 in GDM placentas was significantly higher than that in normal controls (1.70 ± 0.63 vs 1.00 ± 0.56,t=3.68,P＜0.01), and positively correlated with fetal weight (r=0.8501, P＜0.01); on-line analysis showed that CTD-2012K14.6 was located at chr16:67,549,214-67,563,958, which was located in the intron of CCCTC-binding factor( CTCF); Up-regulating CTD-2012K14.6 could significantly reduce the expression of CTCF mRNA and protein, and increase the expression of insulin-like growth factor-Ⅱ( IGF-Ⅱ) mRNA and protein, while down-regulating CTD-2012K14.6 could significantly increase the expression of CTCF mRNA and protein, and reduce the expression of IGF-ⅡmRNA and protein. Conclusion The CTD-2012K14. 6 may play an important role in the pathogenesis of GDM related macrosomia by upregulating the expression of CTCF and IGF-Ⅱ.

This article was aimed to study the effect of Baohe granules for patients with chronic heart failure (CHF) of traditional Chinese medicine (TCM) syndrome and the effect of gastrointestinal hormone secretion. Patients with CHF were used as the object of study. A total of 80 selected patients were divided into 2 groups. The control group was treated with western medicine anti-heart failure therapy. The treatment group was treated with the combination of Baohe granules. All patients were compared in aspects of TCM efficacy, symptom score and serum gastrin, motilin secretion after two-week medication. The results showed that both treatments can significantly improve the TCM syn-drome and symptom total score of CHF patients. And the effect of the treatment group with Baohe granules was bet-ter. The TCM single symptom integral was also obviously improved in the treatment group combined with Baohe granules, which included heart palpitations, shortness of breath, abdominal distension, and loss of appetite. The GAS and MTL levels of CHF patients were significantly increased in the treatment group. It was concluded that the treat-ment combined with Baohe granules can improve CHF patients with TCM syndromes, symptoms and gastrointestinal hormone secretion. Thus, it contributed to the stability of the disease condition. It can slow the disease progression and improve prognosis. So it is worth using widely in the clinical practice.

Highly conjugated linear molecular wires are one of the basic elements for constructing molecular electronic devices. Among these conjugated compounds, ferrocene-terminated compounds as well as their derivatives have been widely studied because of their ideal electrochemical activity. Based on these, a new ferrocene-terminated phenylethynyaniline ( Fc-NH2 ) was synthesized by Sonogashira cross coupling reaction. The structure of the target compound was identified by infrared ( IR) , nuclear magnetic resonance ( NMR) , mass spectra ( MS) and cyclic voltammetry ( CV) . Combined the graphene-chitosan ( GH-CS) and Fc-NH2 , a new composite of GH-CS/Fc-NH2 was prepared and then used for immobilization of Cytc to prepare the GH-CS/Fc-NH2/Cytc/GCE. It was found from the CV result that a pair of peaks near-0. 2 V appeared which can be attributed to Cytc. The GH-CS/Fc-NH2/Cytc modified GCE showed good catalysis towards NaNO2 , and good linear relationship was found in the range of 1 ×10-7-1. 5 ×10-4 mol/L,and the determination limit was bellow 4×10-8 mol/L. Therefore, cytochrome c (Cytc) can be immobilized on the GH-CS/Fc-NH2 and the direct electron transfer can be realized between the electrode and solution and shows good prospect for detection of NaNO2 .

Objective:To analyze the clinical outcome and feasibility for patients who underwent total parathyroidectomy without autotransplantation (TPTX) for secondary hyperparathyroidism (SHPT).Methods:From April 2012 to December 2015,220 SHPT patients underwent TPTX in the department of Breast and Thyroid Surgery of China-Japan Friendship Hospital.The clinical data and effect were assessed retrospectively.Results:All the 220 patients were on permanent dialysis with mean duration of dialysis (7.93 ± 3.75) years.A durable reduction in mean PTH,Ca and P were observed after TPTX (P＜0.01).The mean hospital stay was (7.8 ± 2.8) days.TPTX produced a rapid improvement in clinical symptoms.Incidence of hypocalcemia was 73.46％.Severe complications such as recurrent laryngeal nerve palsy or inactive dynamic osteopathia,haven't been observed postoperatively.The rate of persistent status (PTH≥300 pg/mL) was 9.1％.One (0.45％) died of infectious shock perioperatively.Conclusions:TPTX was a safe and feasible surgical procedure for patients with SHPT.It was worth of being applied.Not missing the parathyroid during operation was the key point for successful TPTX.Intensive monitoring and maintaining stable normocalcemia were the key point to reduce complication.

The paper described the necessity of social capital utilization for public hospitals, and analyzed the model and characteristics of public hospital financing. It is pointed out that the key to the public-benefit nature in the financing calls for distinguishing responsibilities of the government and the market, defining the reasonable level and manner for investors' return, and building corresponding incentive mechanism and supervision mechanism.

Objective To evaluate the functional changes of visual cortex (V1) in patients with primary open angle glaucoma (POAG) by fMRI retinotopic mapping technology. Methods Fifteen POAG patients and 15 healthy volunteers underwent stimulations with fMRI retinotopic mapping stimulus and contrast-reversing checkerboard patterns stimulus on a Siemens Trio 3.0 T MRI whole-body scanner for functional data collection. Comparisons of V1 fMRI responses between the glaucomatous eyes and the healthy eyes of the patients were carried out using paired samples t-test, while independent samples t-test was used to compare V1 fMRI responses and activations between the healthy eyes of patients and the age-, gender- and side- matched eyes of normal people. Differences of V1 cortical functions and visual functions were analyzed by linear correlation analysis when the glaucomatous and the healthy eyes were simulated individually. Results (1) V1 fMRI responses of the individually stimulated glaucomatous eyes[(1.24±0.72)%]were weaker than those of the healthy eyes[(2.18±0.93)%](t=4.757,P<0.01). Comparisons of V1 fMRI responses between the glaucomatous eyes and matched eyes of normal people, as well as between the healthy eyes of patients and the matched eyes of normal people, were performed respectively: the responses in the glaucomatous eyes[(1.24±0.72)%]were weaker than those in the matched eyes of normal people[(2.01±0.65)%](t=-3.011,P<0.01). There was no statistical difference of the responses between the healthy eyes from patients[(2.18±0.93)%]and the matched eyes of normal people[(1.95±0.75)%](t=0.742,P＞0.05). (2) Differences of V1 cortical functions were negatively correlated with those of visual functions in the individually stimulated glaucomatous and healthy eyes (r=-0.887, P<0.01). (3) The activated area indexes of V1 cortexes in the healthy eyes from patients (0.72±0.12) were lower than those in the matched eyes of normal people (0.85±0.09) (t=-3.801, P<0.01). Conclusion Cortical function impairment was in accordance with visual function impairment in glaucoma. Located and quantified measurement with fMRI retinotopic mapping was a useful method for clinical follow-up and evaluation of functional alteration of glaucomatous visual cortex, and a potentially useful means of studying trans-synaptic degeneration of visual pathways of in vivo glaucoma.
