[Summary]_ Severe hypertriglyceridemia is the third common cause of acute pancreatitis following after alcohol abuse and cholelithiasis. Moreover, it is also an important risk factor of cardiovascular events. However, the cases of severe hypertriglyceridemia caused by autoimmune disease were rare in clinical, which would bring the difficulty for diagnosis and treatment. A better understanding of the clinical characteristics, possible pathogenesis, and corresponding therapy of the disease would be helpful, which would reduce the risk of complications, and finally improve both the survival rate as well as quality of life of these patients.

[Summary] In newly diagnosed diabetic patients, fasting plasma glucose, HbA1C , and plasma lipid profiles were measured to analyze the association between HbA1C and plasma lipid profiles. HbA1C might affect plasma lipid profiles in newly diagnosed diabetic patients. Higher HbA1C was associated with the worse plasma lipid profiles and more severe insulin resistance.

Objective To investigate the sustained release of BSA from chitosan-OREC/BSA films coated mats in vitro.Methods The negatively charged cellulose acetate (CA) fibrous mats were modified with multilayers of the positively charged chitosan or chitosan-OREC intercalated composites and the negatively charged bovine serum albumin (BSA) via electrostatic layer-by-layer (LBL) self-assembly technique.The adsorption and rinsing steps were repeated until the desired number of deposition bilayers was obtained.The in vitro BSA encapsulation and release experiments demonstrated that OREC could affect the degree of protein loading capacity and release ficiency of the LBL films coating.Results In the pH-gradient release assay,only a small amount of BSA was released from the mats in 1 h.As the time increased,the release rate of BSA of all the samples gradually went up to the maximum data within 8 h.For the samples with identical number of bilayers and record time,obvious increasing of the release amount could be seen in pH 7.4,in comparison with pH 1.2.Besides,doubling bilayers film-coated mats generally.Meanwhile,it was slightly distinguishable between 5 and 5.5 as well as 10 and 10.5 bilayers (t=0.651～ 1.324,P＞0.05).Interestingly,it could be seen that protein release of the chitosan-OREC/BSA films coated mats remarkably increased compared with that of chitosan/BSA films coated mats(t=2.264～ 2.305,P＜0.05).Conclusion The release of protein in the initial time could be controlled by adjusting the number of deposition bilayers,the outmost layer and the composition of coating bilayers.

Objective To analyze recent 30 years’ regularities in point selection for acupuncture treatment of Parkinson disease and provide reference for its treatment. Methods Parkinson disease, parkinsonism and acupuncture were used as key words. Recent 30 years’ Chinese literature was searched using Wanfang, CNKI, VIP and Chinese biomedical literature database. Selection of main acupoints and scalp acupuncture points, syndrome differentiation-based point selection and meridian tropism of main acupoints were metrologically studied. Results The Du meridian, the large intestine meridian and the gallbladder meridian were mainly selected for acupuncture treatment of Parkinson disease. Taichong(LR3), Baihui(GV20), Hegu(LI4) and Fengchi(GB20) were used as main points. Chorea-tremor control area, motor area and parietotemporal anterior oblique line were often selected as main scalp acupuncture points. Fenglong (ST40), Qihai(CV6), Sanyinjiao(SP6), Yinlingquan(SP9) and Zusanli(ST36) were often used according to syndrome differentiation-based point selection. Conclusion Modern acupuncture doctors select Taichong(LR3), Baihui(GV20), Hegu(LI4) and Fengchi(GB20) as main points, often use scalp acupuncture points and combine points mainly from the Du meridian according to syndrome differentiation in the treatment of Parkinson disease.

BACKGROUND:There is no literature about the treatment according to the mechanism of cervical spine injury classification, especial y for the treatment of extension type cervical fracture/dislocation with merger cases of posterior composite structure damage, whether simple anterior approach can meet the needs of the treatment has no detailed elaboration. This article may analyze from the aspect of cervical spine injury mechanism. OBJECTIVE:To observe the short-term effect of anterior cervical Cage-assisted fusion combined with locking titanium plate internal fixation for the treatment of extension type cervical fracture. METHODS:A retrospective analysis was performed in 15 extension type cervical spine fracture dislocation patients treated with decompression anterior cervical intervertebral disc resection plus bone graft with cage-fusion locking titanium plate internal fixation from June 2006 to March 2011 in the Department of Orthopedics, Xianning Central Hospital, including 10 cases of single segment injury and treatment, and five cases of multiple segment injury and treatment. Japanese Orthopaedic Association score and the neck disability index were compared before and after treatment;the cervical flexion and height were measured according to the antersposterior X-ray film taken before fixation, 1 week after fixation and final fol ow-up.RESULTS AND CONCLUSION:The patients were fol owed-up for 8-37 months. One case had Cage mild sinking and shift, and there was no internal fixation breakage or loosening in al the patients. Transient pharyngeal discomfort was observed in 11 patients. Compared with the preoperation, the Japanese Orthopaedic Association score, neck dysfunction index, fusion segment cervical flexion and fusion segment intervertebral disc height were significantly improved at 1 week after fixation and final fol ow-up (P<0.05). There were no significant differences between 1 week after fixation and final fol ow-up (P>0.05). The short-term effect of decompression anterior cervical intervertebral disc resection plus bone graft with cage-fusion locking titanium plate internal fixation for the treatment of extension-type cervical fracture is good.

Objective To investigate the alteration of energy metabolism and oxidative injury in the myocardia suffering from lethal ventricular tachyarrhythmia (LVTA). Methods Two LVTA-SCD SD rat models, induced by aconitine injection or coronary artery ligation (CAL), respectively, were developed. Rats that died from over-anaesthesia or CAL-induced heart failure were served as their controls, respectively. Mitochondrial membrane potential (MMP), reactive oxygen species (ROS), malonaldehyde (MDA), phosphocreatine (PCr) in the ventricular myocardia, and serum troponin I (cTnI) were detected, and compared between LVTA rats and their controls. Results Fourteen ACO-LVTA and six CAL-LVTA rats were successfully developed. As compared to their controls, ACO-LVTA and CAL-LVTA rats had higher ROS and MDA content, and lower concentration of PCr in the ventricular myocardia. MDA content in ACO-LVTA group is signiifcantly higher than that of its control (P<0.05). MMP in myocardia of ACO-LVTA is lower than that of its control, but is higher than those of two CAL groups. Serum cTnI in rats of both LVTA models is higher than those of their controls and pre-treated control. Specially, serum cTnI in CAL-LVTA was signiifcantly higher than that of ACO-LVTA and its control (P<0.01). The myocardial ROS content is correlated with the duration of VT and VF (P<0.05), with correlation coefifcients being 0.44 and 0.46, respectively. Conclusions After LVTA, the ventricular myocardia had lower MMP and PCr content, higher concentration of ROS, MDA, as well as higher serum cTnI than their controls, indicative of oxidative injury and alteration of energy metabolism under LVTA-SCD.

Objective To investigate the changes in myocardial proteomics in the late phase of limb ischemic preconditioning (LIP) in rats.Methods Twelve pathogen-free adult male Sprague-Dawley rats,aged 8-9 weeks,weighing 260-280 g,were randomly assigned into LIP group (n=6) and control group (group C,n=6) using a random number table.Limb ischemia was preceded by 3 cycles of 5-min ischemia which was induced by ligation of the root of the right hindlimb with a rubber band followed by 5-min reperfusion in group LIP.At 24 h after LIP,the tissues were obtained from the left ventricle,and the isobaric tags for relative and absolute quantification technique and liquid chromatography-mass spectrometry were applied to detect the differences in protein expression profiles between the two groups (the difference in expression between the two groups＞ 1.2 times and P＜0.05).The identified differentially expressed proteins were analyzed using the bioinformatics,and some were further verified by Western blot.Results A total of 55 proteins were identified to be differentially expressed,and among the 55 proteins,the expression of 35 proteins was up-regulated,and the expression of 20 proteins was down-regulated.Bioinformatics analysis showed that most of the 55 proteins were organelles,cell membrane or macromolecular compounds,were involved in the process such as metabolism,biological regulation,stress response and signal transduction,and showed functions such as the binding affinity to molecules,catalytic activity,anti-oxidant activity,and modulation of the activity of enzyme.The results verified by Western blot were consistent with those shown by using the isobaric tags for relative and absolute quantification analysis.Conclusion The late phase of LIP can induce changes in the expression of the 55 proteins involving regulation of energy metabolism,anti-oxidant action,regulation of gene expression,and protein folding and degradation in the myocardium,which may be the mechanism of myocardial protection in rats.

SARS coronavirus (SARS-CoV) develops an antagonistic mechanism by which to evade the antiviral activities of interferon (IFN). Previous studies suggested that SARS-CoV papain-like protease (PLpro) inhibits activation of the IRF3 pathway, which would normally elicit a robust IFN response, but the mechanism(s) used by SARS PLpro to inhibit activation of the IRF3 pathway is not fully known. In this study, we uncovered a novel mechanism that may explain how SARS PLpro efficiently inhibits activation of the IRF3 pathway. We found that expression of the membrane-anchored PLpro domain (PLpro-TM) from SARS-CoV inhibits STING/TBK1/IKKε-mediated activation of type I IFNs and disrupts the phosphorylation and dimerization of IRF3, which are activated by STING and TBK1. Meanwhile, we showed that PLpro-TM physically interacts with TRAF3, TBK1, IKKε, STING, and IRF3, the key components that assemble the STING-TRAF3-TBK1 complex for activation of IFN expression. However, the interaction between the components in STING-TRAF3-TBK1 complex is disrupted by PLpro-TM. Furthermore, SARS PLpro-TM reduces the levels of ubiquitinated forms of RIG-I, STING, TRAF3, TBK1, and IRF3 in the STING-TRAF3-TBK1 complex. These results collectively point to a new mechanism used by SARS-CoV through which PLpro negatively regulates IRF3 activation by interaction with STING-TRAF3-TBK1 complex, yielding a SARS-CoV countermeasure against host innate immunity.
