Journal of Chongqing Medical University 2003;0(06):-
Objective:To study the curative effect and reliability of fastigial nucleus stimulation (FNS)in treating nonmalignant arrhythmia. Methods:In a random period,FNS was used to treat 45 patients,who consulted doctors for repetitive palpitation,had cardiac arrhythmia (supraventricular premature beats,supraventricular runs,ventricular premature beats)confirmed by 24 h Holter monitoring electrocardiogram,and whose state of illness did not improve after being treated by one or several antiarrhythmic drugs. After those patients were treated by FNS 40 minutes a time,two times a week,for 15 times,the changes of 24 h Holter monitoring electrocardiogram were observed. Results:Before and after treatment by FNS,the numbers of SVPB were (3 358.5?5 044.0)/24 h and (1 142.8?2 722.3)/24 h respectively;those ofVPBwere(10 469.7?9 464.9)/24 h and(4 379.4?8 143.3)/24 h respectively;normalized low frequencies(LFnorm)were(35.28?7.04)nU and(31.82?7.35)nU respectively;normalized high frequencies(HFnorm)were (24.32?4.18)nU and (26.84?4.66)nU respectively. LF/HF was 1.47?0.32 and 1.21?0.29 respectively. The differences between pre-treatment and post-treatment indices were all statistically significant (P

Objective To investigate the effect of vitamin D on pulmonary function in patients with chronic obstructive pulmona-ry disease,and to explore its possible mechanism.Methods Patients with chronic obstructive pulmonary disease admitted in the hospital were randomly divided into 2 groups,one group of patients were given regular COPD treatment (control group,30 cases), the other group of patients were given vitamin D on the basis of conventional therapy(experimental group,30 cases).Pulmonary function test and C reaction protein (CRP)determination in the 2 groups were performed,the contents of PaO2 ,PaCO2 were also determined.Results Compared with the control group,lung function improvement in experimental group were more obvious,and the the number of acute attack significantly reduced(P <0.05).The concentration of CRP in experimental group was significantly lower after treatment than before treatment(P <0.05),while the concentration of CRP in control group didn′t change significantly (P >0.05).Conclusion Vitamin D contributes to the improvement of pulmonary function in patients with COPD,and its mecha-nism might relate to the reduction of inflammatory reaction.

Objective To investigate physical activities of preschool children by gender and to explore the effects of activity type on bone indexes.Methods During 2009 and 2010,397 preschool children of 3-5 years old were randomly selected from 4 kindergartens in Chengdu Province of China.Ultrasound bone analyzer was used to assess children's bone mass.A physical activity questionnaire was completed by parents to evaluate physical activities at leisure time.Student's t test and least square regression were used for data analysis.Results Concerning activity types,boys spent more leisure time on running and Wushu than girls did (t values were 1.94 and 2.84,respectively ; both P < 0.05).However,girls spent more time on dancing (0.78 h),jumping rope (0.08 h) and manual labour (0.22 h) each day (t values were-9.50,-3.43 and-1.92,respectively; all P < 0.05).The weekly total exercise time and energy consumption per unit of body weight of girls vs.boys were 7.29 vs.6.51 h and 127.57 vs.113.85 kJ (t values were 2.63 and 2.04,respectively ; both P < 0.05).About per day time on sleeping and per week time on watching television,there were no significant difference between boys and girls (t =0.180,0.520;P >0.05).But boys spent more time on electronic game and computer than girls (t =0.760,2.510;P < 0.05).The normalized correlation coefficient for bone mass and moderate physical activities or jumping was 0.184 and 0.275,respectively (both P < 0.05).Conclusions Our data suggest that preschool children's bone volume may be positively correlated with moderate physical activities and jumping activities.Introducing some moderate physical activities or activity appliance,toys and playing fields as well as increasing professional training might be helpful.

Objective To investigate the clinical and electroencephalogram (EEG) features of patients with idiopathic generalized epilepsy in adults with phantom absences.Methods Six patients were referred to the clinic of epilepsy from April,2007 to December,2011.They all had clinical assessment,EEG,or video EEG confirming absences seizure.Results Six patients showed the following similar clinical-EEG features:(1) mild ictal impairment of consciousness associated with generalized 3.0-3.5 Hz spike and slow wave discharges; (2) late-onset generalized tonic-clonic seizures; (3) absence status epilepticus with or without secondary generalized tonic-clonic seizures; (4) generalized discharges were mostly seen in three types in the awaking stage:fragmented discharge (<4 s),brief discharge (4-10s) and long-time discharge (> 10 s).None of the patients had myoclonic jerks or photosensitivity.One patient' s mother had a history of generalized tonic clonic seizures.One patient had a history of children absence epilepsy and one patient had a history of febrile convulsion in the age of 1-3.Conclusion Idiopathic generalized epilepsy with phantom absences has distinct clinical and EEG features and may become a new idiopathic generalized epilepsy syndrome in adults.

Objective To investigate in vitro porcine myocardial shear modulus using real-time shear wave elastography.Methods Shear wave elastography was used on four in vitro porcine hearts.The probe was placed parallel to the long or short-axis of the heart on the anterior wall of the left ventricle,and myocardial shear modulus were measured in subepicardial,middle,subendocardial layers,respectively.Results Shear modulus of subepicardial,middle,subendocardial myocardium were (46.04 ± 17.07)kPa,(87.70 ± 29.67) kPa,( 115.73 ± 30.04) kPa,respectively,when the probe was placed parallel to the long-axis of the heart; whereas those were (78.71 ± 26.48) kPa,(77.08 ± 34.00)kPa,(70.69 ± 41.38) kPa,respectively,when the probe was placed parallel to the short-axis of the heart.Conclusions By using realtime shear wave elastography,the shear modulus values measured in subepicardial,middle,subendocardial myocardium of the left ventricle are different,even myocardium in the same location appears different shear modulus values when the probe orientation are different.

Objective To investigate the relationship between serum omega-3 polyunsaturated fatty acid (ω-3PUFA) and insulin resistance(IR) in patients with type 2 diabetes mellitus and non-alcoholic fatty liver disease (NAFLD). Methods This trial involved 51 patients of type 2 diabetes mellitus with NAFLD (G4 group), 50 patients of type 2 diabetes alone(G3 group), 45 patients of NAFLD alone (G2 group) and 42 healthy control subjects (G1 group). Serum ω-3PUFA profile was analyzed with capillary gas chromatography. Insulin resistance was assessed by homeostasis model assessment (HOMA-IR). ALT, AST, γ-glutamyltransferase(GGT) and serum lipids were measured. Results The levels of HOMA-IR were higher in G4 group than those in G3, G2 and G1 group(4. 90 ± 2. 54 vs 2. 38 ± 1.23, 2. 20 ± 1.15, 1.13± 0.42;P<0.05). The level of ALT, AST, GGT, TC, TG, LDL-C were higher in G4 group than those in G3, G2 and G1 group(P < 0. 05). The level of ω-3PUFA was signifieantly lower in G4 group than those in G3, G2 and G1 group(5.68 ±2.02 vs 7. 17 ±2. 38, 6.97±2.32, 10.08±2.76;P <0.05). ω-3PUFA cocentration was negatively correlated with HOMA-IR, TC, TG and LDL-C (r = -0.491, -0. 376, - 0. 462, - 0. 408, P < 0. 05). Conclusions Serum ω-3 PUFA is significantly decreased in patients with type 2 diabetes mellitus and NAFLD. Serum ω-3PUFA is negatively correlated with insulin resistance. ω-3PUEA plays a very important role in the development of diabetes mellitus and NAFLD.
