Objective Evaluation of left ventricular ( LV) function has great clinical significance in patients with early chro-nic kidney disease (CKD).The study was to evaluate whether two-dimensional speckle tracking imaging (2D-STI) technique can offer additional information of cardiac dysfunction in early CKD patients . Methods Conventional echocardiography and 2D-STI echocar-diography were performed in CKD group of 20 patients at stage Ⅱ-Ⅲ and control group of 20 healthy volunteers .LV structure and function were evaluated by conventional echocardiography .Multidirectional strain , strain rate and LV twist parameters were analyzed by 2D-STI technique. Results There was no statistical difference in conventional echocardiographic parameters such as left atrial diam -eter, end-diastolic LV diameter and ejection fraction between CKD group and control group .By applying 2D-STI technique, CKD group had significantly decreased value of global longitudinal strain (-19.8 ±2.4)%and strain rate(-1.1 ±0.3)S-1 in comparison to control group(-22.6 ±2.1)%、( -1.8 ±0.2)S-1, along with significant increase in the values of maximum LV rotation (11.6 ± 4.4)°and LV twist(19.6 ±3.8)°in comparison to control group(8.2 ±3.7)°、(13.5 ±3.6)°(P<0.05).There was no differences in both global circumferential and radial deformation parameters as well as maximum rotation value of LV assist device between two groups(P>0.05). Conclusion 2D-STI can detect subclinical LV dysfunction sensitively in early CKD patients .

Objective To evaluate sevoflurane inhalation and propofol combined with ketamine total venous anesthesia in pediatric laparoscopic surgery of oblique inguinal hernia.Methods Seventy ASA Ⅰ children were randomly divided into two groups,35 children in every group.Children in group S were appliedsevoflurane inhalation[the minimum alveolar concentration(MAC)of sevoflurane was 1.0-1.5],children in group PK were applied ketamine inhalation and total venous anesthesia of propofol[80μg/(kg·min)]with ketamine[20μg/(kg·min)].Compared the time of anesthesia induction,tracheal catheter extubation,anesthesia recovery between the two groups.The mean arterial pressure(MAP),heart rate,pulse oxygen saturation(SpO_2)during anesthesia were compared.During 2 days after operation,the adverse effects such as nausea and vomit,lower grade of sleep quality were also compared.Results Compared with group PK,the time of anesthesia induction,tracheal catheter extubation and anesthesia recovery in group S were shorter (P<0.05),the incidence of emergence agitation in group S was higher(20.0%,7/35 vs 2.9%,1/35)(P<0.05).But nausea(17.1%,6/35),vomit(31.4%,11/35)and lower grade of sleep quality(54.3%,19/35)were higher in group PK than those in groups(all 2.9%,1/35)at 1 day after operation(P<0.05).The incidence of lower grade of sleep quality at2 days after operation in group PK(14.3%,5/35)was higher than that in group S(0)(P<0.05).Cardiovascular effects of children,such as MAP and heart rate during the period of tracheal catheter extubation in group S was higher than that in group PK.Conclusion Sevoflurane inhalation and propofol combined with ketamine total venous anesthesia in pediatric laparoscopic surgery of oblique inguinal hernia still has some disadvantages,the anesthesia technology is selected by anesthesia method and medicine combination.

Objective To investigate the effect of microRNA-21 (miR-21) antisense oligonucleoti-de on collagen synthesis in the rat hepatic satellite cells ( HSCs) .Methods Rat hepatic stellate cells were isolated and cultured; the miR-21 antisense oligonucleotide was transfected into HSCs with lipofectamine 2000;after incubation 48 h, the HSCs were collected.The expression of miR-21 was detected with reverse transcription polymerase chain reaction ( RT-PCR) , andα-smooth muscle actin (α-SMA) protein in HSCs with Western blot.The cell proliferation was assayed with methyl thiazolyl tetrazolium ( MTT) method.Re-sults Compared to scrambled control group, the expression of miR-21 was reduced by 76%( P <0.01), the proliferation activity of HSCs was reduced by(26 ±3)%( P <0.01), the expressions of type I and III collagen proteins were reduced by(61 ±7)%and (48 ±6)%( P <0.01).Conclusions The miR-21 an-tisense oligonucleotide could reduce significantly the expression of miR-21, and inhibit HSC proliferation and extracellular matrix production.

Objective To evaluate the relationship between severity of airway obstruction and peripheral arterial stiffness in patients with chronic obstructive pulmonary disease (COPD).Methods 81 COPD patients [aged (78.32 ± 6.98)yrs,73 males,8 females] from Jan 2008 to Oct 2012 were enrolledin Geriatric Department of Peking University First Hospital.All patients underwent spirometry and Holter evaluation,while age,sex,BMI,smoking pack-years,medical history,blood levels of lipid profiles,glucose,high sensitivity C reactive protein (hsCRP)and arterial oxygen pressure (PaO2)were recorded.The severity of airway obstruction was evaluated by spirometry.The patients were divided into two groups:mild/moderate group [forced expiratory volume in one second (FEV1％) predicted ≥ 50 ％,n=51] and severe group (FEV1％ predicted ＜ 50％,n=30).24-hour average heart rate (HR)was assessed by holter.Arterial stiffness was assessed by the brachial ankle pulse wave velocity (baPWV).The baPWV increment was considered to be a direct witness of arterial stiffness increase.Blood levels of lipid profiles,glucose,arterial oxygen pressure (PaO2)and hsCRP were compared between the two groups.Results Age,gender,smoking index,medical history of the two groups were matched.BMI was less in severe group than in mild/moderate group [(22.8± 4.2) kg/m2 vs.(25.3± 3.2) kg/m2,t=3.017,P＜0.05].24-hour average HR was higher in severe group than in mild/moderate group [(77.4± 12.7)bpm vs.(70.8± 9.6)bpm,t=-2.602,P＜0.05].The PaO2 was lower in severe group than in mild/moderate group [(74.6±13.0)mmHg vs.(82.4± 13.1)mmHg,t=2.456,P＜0.05].There were no differences in blood lipid profile and glucose levels between the two groups.76 patients (93.4％)were detected with peripheral arterial stiffness by baPWV＞14.00 m/s.baPWV was significantly increased in severe group as compared with mild/moderate group [(20.77 ± 3.71) m/s vs.(18.84 ± 1.88) m/s,t=-2.109,P＜0.05].hsCRP was significantly higher in severe group than in mild/moderate group [[(6.51±5.66)mg/L vs.(3.27±3.34)mg/L,t=-2.658,P＜0.01].Conclusions The morbidity of peripheral arterial stiffness is increased in patients with COPD.Progression of arterial stiffness is related to the severity of airway obstruction,which may be related to chronic inflammation,hypoxia,or excessive sympathetic activation.

OBJECTIVE:To provide reference for improving the teaching quality of the course of Drug Abuse and ADR Moni-toring in pharmacy master degree candidates. METHODS:In Pharmacy College of Jilin University,traditional teaching method was adopted among pharmacy master degree candidates of grade 2014(n=30,control group);case teaching method was adopted for the course of Drug Abuse and ADR Monitoring among those of grade 2015 (n=32,observation group). The teaching effects were evaluated by questionnaire and examination. RESULTS:Theoretical examination result and case analysis score as well as the rate of excellent case analysis score in observation group were all significantly higher than control group,with statistical signifi-cance (P<0.05). The satisfaction degree of observation group was significantly higher than that of control group in respects of teaching methods,arousing interest in classroom learning,establishing the awareness of safe and rational drug use,with statistical significance (P<0.05). CONCLUSIONS:For the course of Drug Abuse and ADR Monitoring in pharmacy master degree candi-dates,case teaching method improves students'exam results,stimulates students'interest and enthusiasm,promotes the establish-ment of students'safe and rational drug use consciousness and improves teaching quality.

Objective To assess the coronary flow reserve in the patients with systemic lupus erythematosus(SLE)by transthroracic echocardiography(TTE).Methods Coronary sinus blood flow of 24 SLE patients and 18 matched healthy controls were assessed by TTE.The coronary flow reserve was calculated as the ratio of hyperemic to baseline blood flow.Hyperemia was induced by intravenous administration of dipyridamole.Results Adequate recordings of blood flow in the coronary sinus under both conditions were obtained by TTE in all study subjects.Patients with SLE were found to have significantly decreased coronary flow reserve comparing with normal SUbiects(1.55±0.21 versus 2.51±0.33.P＜0.01).Conclusions Coronary flow reserve can be measured by TTE in SLE patients,Coronary flow reserve is impaired suggesting that SLE patients may have subclinical coronary artery disease.
