BACKGROUND:The correlation between blood stasis syndrome and non-blood stasis syndrome of lumbar intervertebral disc protrusion remains unclear.
OBJECTIVE:To construct serum protein pattern model for diagnosing blood stasis syndrome of lumbar intervertebral disc protrusion.
METHODS:A total of 180 cases were included in this study and divided into treatment group (120 patients with lumbar intervertebral disc protrusion) and control group (60 healthy cases from physical examination). Furthermore treatment group was equal y assigned into blood stasis syndrome subgroup and non-blood stasis syndrome subgroup, with 60 cases in each subgroup. The involved cases were wel matched in nations, genders and ages. Serum samples of peripheral blood from the 180 cases were col ected. Surface-enhanced laser desorption/inionation time of flight mass spectrometry and ProteinChip technology were employed to detect and plot protein mass spectrum. The protein peak values were identified using Biomarker Wizard software. Then serum diagnosis model of blood stasis syndrome of lumbar intervertebral disc protrusion was established. The obtained models were verified through double blind method. The differential proteins were searched by ExPASy data.
RESULTS AND CONCLUSION:We detected that peak values of eleven proteins had statistical significance (P<0.05) from the involved 180 cases. Among them, two proteins were highly expressed while the other nine proteins were lowly expressed. Serum protein pattern model for diagnosing blood stasis syndrome of lumbar intervertebral disc protrusion was established through Biomarker Patterns software, and the sensibility was 86.667%, the specificity was 94.167%, the positive predictive value was 88.136%. There are a variety of abnormal y expressed proteins in the serum of the patients with blood stasis syndrome of lumbar intervertebral disc protrusion. The serum protein pattern model involved eleven different proteins can be used to diagnose blood stasis syndrome of lumbar intervertebral disc protrusion.

Due to the low molecular weight and simple structure, the production of specific antibodies against acrylamide is unavailable. In this study, a novel hapten was synthesized through the derivatization of acrylamide and 4-mercaptophenylacetic acid. The hapten was then coupled to carrier protein and used to immunize New Zealand rabbits. Polyclonal antibody which showed specific binding to the acrylamide derivative ( hapten) was obtained. The antibody was labeled with horseradish peroxidase ( HRP) and used to develop a direct competitive enzyme-linked immunosorbent assay ( dc-ELISA) . The dc-ELISA was used to determine the content of acrylamide derivative, and then transferred to the content of acrylamide. The assay showed an IC50 value of 45. 49 μg/L, a limit of detection of 3. 0 μg/L and the linear range of 9. 2-195 μg/L for acrylamide. The recovery of acrylamide from spiked food sample was determined ranging from 83 . 6% to 112 . 7%. Good correlations between the results of dc-ELISA and standard HPLC-MS/MS were obtained. The proposed dc-ELISA is suitable for the determination of acrylamide in food samples.

OBJECTIVE: To evaluate diagnostic significance of the noninvasive and objective 320-slice CT scan in the high pharynx resilience in the patients with obstructive sleep apnea/hypopnea syndrome. METHOD: Fifty patients with OSAHS and 10 patients with pharyngeal paraesthesia were included in the study. 320 slice CT scan was used to measure the sagittal diameters, transverse diameters and sectional area of the retropalatal region, retroglossal region. Calculating the pharynx wall resilience. Analyzing the correlativity of pharynx wall resilience, BMI and AHI. Fiber endoscope was used to assess the subsidence percentage of the pharynx wall. RESULT: Between OSAHS patients and pharyngeal paraesthesia patients, there was obviously difference in the retropalatal region and retroglossal region upper airway. The pharynx wall resiliences of retropalatal region were much more than that of retroglossal region. The later pharynx wall resiliences were much more than the fore-to-aft pharynx wall resiliences in the retropalatal region. BMI, AHI and the pharynx wall resilience were positive correlative to each other. But AHI and the pharynx wall resilience was nonlinear correlative. There was a good concordance between the pharynx wall resilience detected by 320CT and subsidence percentage of the pharynx wall detected by fiber endoscope. CONCLUSION 320 slice CT is a kind of simple, rapid and objective method to localize the high resilience area of upper respiratory tract, which can be benefit to the clinical diagnosis, the etiological study and the treatment of OSAHS. Based on physical examination, we propose that only one time of CT scan to the patients' upper airway at the Muller' stage is enough to localize the stenosis area, which can reduce radiation dosage dramatically.

Objective To study the clinical value of electronic bronchoscope in diagnosis and treatment of recurrent dyspnea in neonates.Method From October 2014 to October 2017,the clinical data of recurrent dyspnea receiving electronic bronchoscopy examination and treatment in the neonatal intensive care unit of our hospital were retrospectively selected.Their clinical characteristics and treatment effects were summarized and analyzed.Result A total of 171 infants of neonatal recurrent respiratory infections were examined using electronic bronchoscope.The top four causes included endo－tracheo－bronchitis in 78 cases (45.6%), laryngomalacia, and tracheobronchomalacia in 22 cases (12.9%), airway stenosis in 14 cases (8.2%) and esophagotracheal fistula in 12 cases ( 7.0%).The complications of intraoperative and postoperative included decline of percutaneous oxygen saturation and /or heart rate (20.5%, 35/171), mucosal bleeding (12.3%, 21/171 ), and fever after bronchoalveolar lavage.Electronic bronchoscopy examination confirmed all the 171 neonates′diagnosis and some of them recovered after corresponding treatment.78 cases of infants with endo－tracheobronchitis were all cured.22 cases of laryngomalacia and tracheobronchomalacia and nine patients with airway stenosis improved and were discharged after treatment . One patient with subglottic stenosis received bronchoscopic holmium laser ablation therapy and the airway significantly expanded.No re－stenosis was found during follow－up.Conclusion Electronic bronchoscopy is an important method to determine the cause of recurrent dyspnea in newborns , and it′safe,reliable and can play a therapeutic role in some neonates.

Objective To investigate the relationship between resting heart rate (RHR)and carotid artery structure in young hypertensive patients.Methods A total of 663 primary hypertensive patients aged between 18 and 45 (38.01 ± 5.78) were chosen from the First Affiliated Hospital of Xinjiang Medical University from January,2009 to January,2012.Patients under this study were divided into three groups according to their RHRs:group A (RHR＜70 bpm,n=163),group B(70 bpm≤RHR＜80 bpm,n=268),group C (RHR≥80 bpm,n=232).Data on bilateral carotid artery intima-media thickness,common carotid artery diameter were detected by carotid ultra-sonography.Indexes of carotid artery were analyzed by both variance and bi-variate correlation analysis.Results 1)Differences in the blood pressure among three groups showed statistical significance (P＜0.01),with diastolic pressure in group A higher than in group B (P＜0.05),while both systolic and diastolic pressure in group C higher than in group B (P＜0.01).2)In group A,the right carotid artery diameter was higher than in group C(P＜0.05) and the left carotid artery diameter higher than in group B(P＜ 0.05) with the left carotid artery diameter higher than in group C (P＜0.05).3) Significant positive correlations were found between RHR and blood pressure (r =0.112,0.118) and negative correlation between RHR and left carotid artery diameter (r=-0.89).However,correlation between RHR and right carotid artery diameter was not significant (r=-0.075,P=0.068).Conclusion When blood pressure had an increase,we found that the carotid artery diameter was decreasing along with the increasing RHR among the young hypertensive patients.

Objective: To explore the in vitro and in vivo effect of GP73 on the proliferation, invasion and metastasis in hepatocellular carcinoma. Methods: GP73 gene was knocked out using CRISPR/Cas9 gene editing system in H22 and HepG2 cells, and stable knock out strains were constructed. The knockout efficiency was measured by western blot. Colony formation assay was used to detect the effect of GP73 on long-term survival ability. Cells were then highly synchronized in G₁ phase upon treatment with cell synchronization reagents (mimosine), and the percentage of cells in G₂/M phase at different time points was detected by flow cytometry. The invasive and metastasis abilities of hepatocellular carcinoma cells were detected by Transwell™ assay. Furthermore, the tumor formation abilities in vivo were examined using subcutaneous xenograft models. Results: The stable knock out strains of GP73 in H22 and HepG2 cells were successfully established via puromycin selection. The number of colonies of GP73 knock out groups in HepG2 and H22 cells 10 days after transfection were 400±70 and 248±60, respectively. They were significantly lower than those in the control groups (980±40 and 1 100±50, respectively; P<0.01). In addition, GP73 knockout slowed down the cell cycle progression. Moreover, the cell numbers that had migrated to the underside of the filters were 312±50 and 305±49 in the GP73 knockout groups of HepG2 and H22 cells, respectively, significantly lower than 1 540±87 and 1 270±86 in the controls (P<0.01). For transwell invasion assay, the cell number that had invaded into the underside of the filters were 230±47 and 238±54 in the GP73 knockout groups of HepG2 and H22 cells, respectively, significantly lower than 648±74 and 596±63 in the controls(P<0.01). Furthermore, the tumor volume of GP73 knockout group was (70±170) mm^3, significantly smaller than (1 200±110)mm³ of the control guoup (P<0.01). Conclusions GP73 knockout decreases the proliferation, invasive and migratory abilities of HepG2 and H22 cells in vitro and in vivo. GP73 may contribute to tumorigenesis of hepatocellular carcinoma.
