BACKGROUND:The effect of dimethyl sulfoxide cryoprotectants has been got a lot of verification in the low-temperature medical applications. But there is no literature addressing microdialysis detection of dimethyl sulfoxide cryoprotectants. OBJECTIVE:To investigate the microdialysis relative recovery of different concentrations of dimethyl sulfoxide cryoprotectants used for limb reattachment. METHODS:In vitro linear probe relative recovery of different concentrations of dimethyl sulfoxide (2%, 5%, 8%) was detected by retrodialysis gain and loss method. The correction in vivo experiment was done to estimate dimethyl sulfoxide relative recovery in rabbit amputated limbs. RESULTS AND CONCLUSION:The relative recoveries of different concentrations of dimethyl sulfoxide (2%, 5%, 8%) were (49.49±3.56)%, (46.30±1.48)%, (52.66±2.54)%using retrodialysis gain method and (50.99±6.89)%, (43.86±1.35)%, (50.67±0.75)%using retrodialysis loss method. The average recoveries were (49.48±3.18)%and (48.51±4.03)%, respectively. There was no difference in the relative recovery of dimethyl sulfoxide detected using two methods. The change of dimethyl sulfoxide concentration could not influence the retrodialysis gain and loss method calibration results. The recovery was (15.45±4.8)%in vivo. These findings indicate that the microdialysis technology is suitable for dimethyl sulfoxide sampling in vivo that has no obvious influence on the relative recovery.

Objective To research the pathogen characteristics and influencing factors for peritonsillar peripheral space infections in acute tonsillitis patients,so as to take measure to reduce the peritonsillar peripheral space infections.Methods 898 acute tonsillitis patients who received treatment were chosen as study subjects.Bacteria analyzer was adopted to identify pathogens.Chi-square test was used to analyze the univariate factor,and logistic regression analysis was conducted to different factors.Results 228 patients were involved the complications of peritonsillar peripheral space infections(cellulitis in 52 cases or abscesses in 176 cases),and the infection rate was 25.4％.Bacterial cultivation performed in 177 patients and positive results were detected in 107.The top three infections bacteria were Staphylococcus aureus (21.5％),Streptococcus viridians (19.6％) and Klebsiella pneumoniae (15.9％).Univariate factor analysis found that the history diabetes and peritonsillar peripheral space infections,age,acute phase of smoking and drinking,fatigue,nutritional status,class of antibiotic use,tonsillitis type,educational level and the long first diagnosis time were risk factors for peritonsillar peripheral space infections,and the differences were significant (x2 =39.851,8.818,89.041,87.266,30.417,21.499,13.472,64.548,12.223,62.871,70.749,all P ＜ 0.05).Logistic regression analysis found that acute phase of smoking and drinking,age,fatigue,tonsillitis type and the long first diagnosis time were independent risk factors for peritonsillar peripheral space infections patients with acute tonsillitis (OR =2.873,5.311,5.876,0.290,2.244,2.369,all P ＜ 0.05).Nutritional status and educational level had beneficial effect to peritonsillar infections event (OR =0.290,0.461,all P ＜ 0.05).Conclusion Acute tonsillitis is easy to cause peritonsillar peripheral space infection,it should be paid much attention and strengthened prevention.The pathogens causing peritonsillar peripheral space infections in acute tonsillitis is still mainly Staphylococcus aureus.After the analysis of related factors,the certain measures should be taken to reduce the complications rate of peritonsillar peripheral space infections in acute tonsillitis.

Objective To investigate the association between arterial stiffness of the common carotid artery(CCA)and insulin resistance in hemodialysis patients. Methods Arterial stiffness index β of CCA was evaluated by an ultrasonic phase-lock Echo-tracking system in 80stable non-diabetic hemodialysis patients.Insulin resistance was detected by the homeostasis model assessment method(HOMA-IR).Plasma hemoglobin,serum albumin,total cholesterol,high density lipoprotein,low density lipoprotein,triglyceride,lipoprotein(a),ApoA1,ApoB,CRP,calcium,phosphorus and creatinine were determined by standard methods. Results The stiffness index β was 11.41±4.13 in patients with previous cardiovascular disease(CVD)and 9.75±3.63 in those without CVD(P＜0.05).The stiffness index β was positively correlated with HOMA-IR(r=0.321,P＜0.01),as well as with age(r=0.376,P＜0.01),pulse pressure(r=0.267,P＜0.05),and duration of hemodialysis(r=0.219,P＜0.05).In stepwise multiple regression analysis,HOMA-IR(β=0.228,P＜0.05)and age(β=0.308,P＜0.01)were identified as significant independent variables for stiffness index β of CCA. Conclusions Insulin resistance is associated with aaefial stiffness in nondiabetic hemodialysis patients.The increased arterial stiffness may be the link between insulin resistance and cardiovascular morbidity as well as mortality in hemodialysis patients.

Cardiac hypertrophy is a common physiological or pathological process, and pathological cardiac hypertrophy can lead to heart failure, sudden death, etc. The role of microRNA (miRNA or MIR) in myocardial hypertrophy has gradually attracted public attention. miR-1 plays a certain protective role in the occurrence of cardiac hypertrophy. miR-133 is a key factor in the establishment of mast gene program, which is very important for the development of myocardial hypertrophy. Carvedilol and other drugs can regulate the expression of miR-133. miR-208a plays an important physiological role in the cardiovascular system, and its expression level changes dynamically in a variety of cardiovascular diseases such as cardiac hypertrophy, which is closely related to the progression and prognosis of the disease. The expression of miR-199a is up-regulated in pressure-overload cardiac hypertrophy, and it is found that miR-199a can inhibit autophagy of cardiomyocytes and induce the occurrence of cardiac hypertrophy. miR-200c can protect cardiomyocytes through a variety of pathways. miRNA may become an important biomarker or drug therapeutic target for cardiac hypertrophy. With the deepening of the research on non-coding RNAs including miRNA, its regulation on the occurrence of cardiac hypertrophy and the pathological process of heart failure will be further revealed.
