Chongqing Medicine 2015;(16):2222-2224
Objective To investigate the correlation between S100B protein and the stability of carotid artery arteriosclero‐sis .Methods A total of 200 patients with carotid artery arteriosclerosis(CAS) were assigned as study group ,and then subdivided into stable plaques (SP)group and instable plaques (IP)group ,and 198 whoes age and gender well matched unrelated healthy sub‐jects were enrolled as control group .The levels of S100B and hs‐CRP of the 3 groups were measured by ELESA .All the diagnosis were confirmed by color Doppler and B‐ultrasound .Results The level of serum S100B was significantly higher in IP group than that of SP group and control group(P<0 .01) .There was no statistical significance between IP and SP group in the level of serum S100B(P=0 .07) .The level of hs‐CRP was significantly higher in IP group than that of SP group and control group(P<0 .01) . There was no statistical significance between IP and SP group in the level of serum hs‐CRP(P=0 .59) .Conclusion The increase of serum level of S100B in the IP CAS patients shows that S100B may take part in the pathogenic mechanism of CAS ,and regulating of S100B may become the potential therapeutic targets for CAS .

Objective:To investigate the relationship between rapid eye movement sleep behavior disorder(RBD)and neurofilament light chain(NfL)levels in patients with Parkinson's disease(PD).Methods:General clinical data of 121 PD patients and 38 healthy controls(HC)who visited the Department of Geriatric Neurology of the First Affiliated Hospital of Kunming Medical University from June 2019 to January 2021 were collected in a prospective study.According to the Rapid Eye Movement Sleep Behavior Disorder Questionnaire(RBDSQ), PD patients were divided into a PD with RBD group(PD-RBD, RBDSQ≥6)and a PD without RBD group(PD-NRBD, RBDSQ<6). General clinical data and plasma NfL levels of patients in the groups were compared.In addition, symptoms during exercise, during non-exercise, and sleep quality in the groups were also compared.Results:Plasma NfL levels were higher in the PD group than in the HC group(19.39 ng/L, 12.58-31.78; 14.85 ng/L, 9.78-22.15; Z=-2.492, P<0.05); plasma NfL levels were significantly higher in the PD-RBD group than in the PD-NRBD group and in the HC group(25.29 ng/L, 19.09-34.75; 17.14 ng/L, 11.70-26.67; 14.85 ng/L, 9.78-22.15; Z=-3.434, P<0.01); there was no significant difference in plasma NfL levels between the HC group and the PD-NRBD group( P>0.05). Receiver operating characteristic(ROC)curve analysis showed that, when the plasma NfL cutoff was set at 17.86 ng/L, PD-RBD and PD-NRBD could be distinguished( AUC=0.70, 95% CI=0.60-0.80, sensitivity 82%, specificity 54%). Binary logistic regression identified NfL level as an independent predictor of PD-RBD( β=0.068, OR=1.103, P=0.003). Conclusions:PD-RBD patients have increased plasma NfL levels, which can potentially serve as a biomarker for PD with RBD.

Objective:This study investigated the changes of cortical thickness in patients with Parkinson's cognitive dysfunction.Methods:In this cross-sectional study, general clinical data and head magnetic resonance imaging data were collected from Parkinson's disease(PD)patients and healthy controls who were hospitalized or outpatient in the Department of Geriatric Neurology of the First Affiliated Hospital of Kunming Medical University from January 2019 to December 2020.We observed the changes of cortical thickness in each group, and analyzed the correlation between cortical thickness and cognitive dysfunction in PD.Results:Compared with PD normal cognitive group, the cortical thickness of the left superiortemporal gyrus[(2.7±0.1)mm, (2.4±0.1)mm, t=-4.194], left supramarginal[(2.4±0.1)mm, (2.2±0.1)mm, t=-4.845], right insula[(3.0±0.1)mm, (2.7±0.1)mm, t=-4.170], left parahippocampal[(2.8±0.3)mm, (2.4±0.3)mm, t=-4.164]decreased in PD cognitive impairment group(all P<0.05), and cortical thickness of the right parsorbitalis[(2.5±0.2)mm, (2.4±0.2)mm, t=-4.226], left entorhinal[(3.5±0.3)mm, (3.1±0.4)mm, t=-4.583], left inferiortemporal[(2.7±0.2)mm, (2.5±0.1)mm, t=-6.229], left supramarginal[(2.4±0.1)mm, (2.1±0.1)mm, t=-3.236], right fusiform[(2.8±0.1)mm, (2.5±0.1)mm, t=-5.364], right lingual[(2.0±0.1)mm, (1.9±0.1)mm, t=-3.887], right insula[(3.0±0.1)mm, (2.7±0.2)mm, t=-5.326], right isthmuscingulate[(2.6±0.2)mm, (2.3±0.2)mm, t=-3.743]decreased in PD severe cognitive impairment group, the statistical difference was significant(all P<0.05). The cerebral cortex thickness was positively correlated with Mini-Mental State Examination and different cognitive areas, and negatively correlated with Hoehn-Yahrr grading. Conclusions:Local cortical thinning was observed in PD patients with cognitive impairment, whereas cortical involvement was more extensive in PD patients with severe cognitive impairment.

PURPOSE:
Urosepsis in adults comprises approximately 25% of all sepsis cases, and is due to complicated urinary tract infections in most cases. However, its mechanism is not fully clarified. Urosepsis is a very complicated disease with no effective strategy for early diagnosis and treatment. This study aimed to identify possible target-related proteins involved in urosepsis using proteomics and establish possible networks using bioinformatics.
METHODS:
Fifty patients admitted to the Urology Unit of Lanzhou General PLA (Lanzhou, China), from October 2012 to October 2015, were enrolled in this study. The patients were further divided into shock and matched-pair non-shock groups. 2-DE technique, mass spectrometry and database search were used to detect differentially expressed proteins in serum from the two groups.
RESULTS:
Six proteins were found at higher levels in the shock group compared with non-shock individuals, including serum amyloid A-1 protein (SAA1), apolipoprotein L1 (APOL1), ceruloplasmin (CP), haptoglobin (HP), antithrombin-III (SERPINC1) and prothrombin (F2), while three proteins showed lower levels, including serotransferrin (TF), transthyretin (TTR) and alpha-2-macroglobulin (A2M).
CONCLUSION
Nine proteins were differentially expressed between uroseptic patients (non-shock groups) and severe uroseptic patients (shock groups), compared with non-shock groups, serum SAA1, APOL1,CP, HP, SERPINC1and F2 at higher levels, while TF, TTR and A2M at lower levels in shock groups.these proteins were mainly involved in platelet activation, signaling and aggregation, acute phase protein pathway, lipid homeostasis, and iron ion transport, deserve further research as potential candidates for early diagnosis and treatment. (The conclusion seems too simple and vague, please re-write it. You may focus at what proteins have been expressed and introduce more detail about its significance.).
