ABSTRACT
@#Proteomics is one of the most advanced fields and hotspots in the research of various diseases in recent years. Its development has provided a new research direction for the early diagnosis and treatment of diabetes and has achieved some research results. Early diagnosis is helpful to control the progression of the disease or even avoid surgical treatment, which is of great significance for improving the prognosis of patients. This paper reviews the current status and prospects of proteomic technology and its applications in diabetes as well as its complications with a prospect of the impact of the rapid development of proteomics on diabetes and its positive role in discovering more diabetes biomarkers. In the future research, more attention should be paid to the interconnections between biomarkers.
ABSTRACT
OBJECTIVE:To observe the effects of dexmedetomidine combined with ulinastatin on stress reaction indexes,ex-travascular lung water value(EVLW)and pulmonary vascular permeability indexes(PVPI)and other parameters in one-lung venti-lation(OLV)lobectomy patients. METHODS:A total of 80 patients underwent OLV lobectomy selected from the Affiliated Hospi-tal of Southwest Medical University during Nov. 2015-Nov. 2016 were divided into control group (group N),ulinastatin pretreat-ment group(group U),dexmedetomidine continuous pump group(group D),ulinastatin pretreatment+dexmedetomidine continu-ous pump group(group U+D),with 20 cases in each group. Thirty min before anesthesia induction,all patients were given atro-pine sulfate 0.5 mg intramuscularly and received catheterization of right internal jugular vein and ipsilateral femoral artery under lo-cal anesthesia. Based on that,group N was given 0.9％ Sodium chloride injection 100 mL intravenously;group U was given sodi-um chloride mixed solution 100 mL containing Ulinastatin for injection 200000 U intravenously;group D was given continuous in-travenous pump of Dexmedetomidine hydrochloride injection 2 μg/mL mixed with sodium chloride mixed solution at 1 μg/(kg·h), and after induction intravenous pump at 0.5 μg/(kg·h)until the end of surgery;group U+D was given Sodium chloride mixed so-lution containing 200000 U ulinastatin 50 mL and 4 μg/mL dexmedetomidine sodium chloride mixed solution 50 mL intravenously (same dose as above during induction period and maintenance period). The levels of blood glucose,partial pressure of oxy-gen [p(O2)],adrenocorticotropic hormone (ACTH),norepi-nephrine (NE),heart rate (HR),cardiac output (CO),sys-temic vascular resistance(SVR),EVLW and PVPI were com-pared among 4 groups 30 min before anesthesia induction(T1),2 h after the beginning of surgery(T2),immediately after extuba-tion(T3)and 12 h after surgery(T4). Liquid intake and output volume were recorded during T2-T4. The occurrence of ADR among 4 groups was observed. RESULTS:There was no statistical significance in each index among 4 groups at T1 (P>0.05). During T2-T4,the levels of blood glucose,ACTH,NE,SVR,EVLW and PVPI in group N were significantly higher than other 3 groups, and group U and D were significantly higher than group U+D,with statistical significance(P<0.05);there was no statistical sig-nificance between U and D(P>0.05). The levels of p(O2)and CO in groups U+D were significantly higher than other 3 groups, with statistical significance (P<0.05);there was no statistical significance among other 3 groups (P>0.05). HR of group N and U were significantly higher than other 2 groups,with statistical significance (P<0.05). There was no statistical significance be-tween group N and U,between group D and U+D(P>0.05). There was no statistical significance in liquid intake or output vol-ume among 4 groups (P>0.05). No obvious ADR was found in 4 groups. CONCLUSIONS:Dexmedetomidine combined with ulinastatin can significantly relieve stress reaction,and reduce the levels of part blood flow and respiratory dynamics indexes as EV-LW,PVPI in patients with OLV lobectomy so as to play lung protective effect.
