Objective To explore the expressions of apoptosis gene Bcl-2 (B-cell leukemia-2) and Bad (bcl-xl/bcl-2-associated death promoter) in lung tissue of mice with acute lung injury (ALI). Method Twenty-four BALB/C female mice were randomly divided into control saline group (n = 6) and ALI group (n = 18). The ALI Group was further divided into 3 subgroups with 6 mice in each subgroup: ALI (4 h) ,ALI (6h) ,and ALI (8h) subgroups. Rats in the normal control group received injection of saline. The ALI models were produced by in-jection of oleic acid (0.9 mL/kg) via vena caudalis, and the criteria were met with the characteristically pathologi-cal changes in the lung tissue. Pathological changes of the lung tissue were examined and scored under light mi-croscopy 4 h,6 h and 8 hours after injury. The expressions of gene Bcl-2 and gene Bad were detected in lung tissue at above set intervals by using RT-PCR. Data of these assays were analyzed by using one-way ANOVA with SPSS version 13.0 software. Statistical significance was established at a P value of less than 0.05. Results The rela-tive magnitude of Bel-2 expression in ALI (4 h), ALI (6 h) and ALI (8 h) subgroups were significantly higher (58.00±5.31), (42.00±4.30), (32.51±10.40) as compared with the control group (24.30±1.00) (F =68.581, P < 0.05). The relative magnitude of Bad expressions in ALI (4 h), ALI(6 h) and ALI (8 h) sub-groups were signiticantly higher (29.32±1.19), (58.64±4.45), (95.12±4.34)as compared with control group (4.01±0.34) (F = 386.902,P < 0.05). The pathological scores ofhmg injury in ALI(4h), ALI (6 h) and ALI (8 h) subgroups were significantly higher (1.82±0.14), (2.52±0.25), (3.45±0.29) as compared with control group (0.27±0.03) (F = 260. 512, P <0.05). Comparisons between groups showed statistical signifi-cances (P < 0.05). Conclusions The aggravation of lung injury induced by oleic acid in mice related to the down-regulation of apoptosis gene Bcl-2 expression and up-regulating apoptosis gene Bad expression in lung tissue.

miRNAs were discovered less than a decade ago, and have emerged as important regulators of gene expression in mammals. A large number of miRNAs have been identified to be located within the intronic regions of protein-encoding genes(host genes) and called intronic miRNAs. The intronic miRNAs may play a key role in regulating the expression and function of their host genes due to the fact that most of them are co-expressed with the host genes. In this paper, the recent advances on the research on potential relationship between intronic miRNAs and their host genes are reviewed.

Objective To investigate the changes of blood lipid,endothelin(ET)and carbohydrate tolerance in simple obesity children.Methods Serum total cholesterol(TC),triglyeride(TG),low density lipoprotein(LDL),endothelin(ET) and oral glucose tolerance test(OGTT) of 436 cases(light obesity group 242,moderate obesity group 138,heavy obesity group 56) were detected respectively.Results The levels of TC,TG,LDL,ET and OGTT in 3 simple obesity groups were all higher than those in control group obviously and there were significant differences.The significant positive correlation between the obesity children serum lipids,ET and obese degrees were observed.Four insulin resistant children were found in heavy obesity group and none in other groups.Conclusions The levels of serum lipids and ET increases in obesity children and the OGTT decreases in some heavy obesity children.For preventing the obesity related health problems,the simple obesity children should be paid more attention to earlier.

Objective To evaluate left atrial function dynamic changes before and after radiofrequency catheter ablation (CA)with persistent atrial fibrillation (AF)and predict the maintain sinus rhythm of postoperative atrial fibrillation by speckle tracking imaging.Methods The study was including 45 cases underwent CA with persistent AF(preoperative 1 week,postoperative 24 hours,3 months,6 months)and 25 normal cases.Left atrial function and strain rate were analysed.These index were measured and calculated:the left atrial diameter index (LADI),left atrial area index (LAAI),left atrial maximum volume index (LAVImax)and left atrial ejection fraction(LAEF),left atrial wall strain rate of left ventricular systolie (SRs),left atrial wall strain rate of left ventricular early diastolie (SRe),left atrial systolic strain rate(SRa) and the average of left atrial wall each phase strain rate.Results ① LADI,LAAI,LAVImax were significantly increased;LAEF,SRs,SRe were decreased significantly;SRa were disappeared with AF compared with the control group.②LADI,LAAI,LAVImax decreased gradually,LAEF,SRs,SRe,SRa were gradually increased with the extension of the follow-up time.③Left atrial average SRs predicted maintenance of sinus rhythm with atrial fibrillation after operation of CA(odds ratio=0.607,95% CI=0.417-0.819,correction of P =0.017)was an independent predictor.Conclusions Speckle tracking imaging can quantitative evaluate left atrial function with persistent AF after CA.Left atrial global reservoir function predicts the efficacy of CA.

Objective To compare the analgesia effects of Oxycodone hydrochloride with Sufentanil in laparoscopic cholecystectomy (LC) anesthesia induction. Method Sixty patients scheduled for elective LC, ASAⅠ or Ⅱ , were randomly divided into two groups (30 in each): Oxycodone group (group O) and Sufentanil group (Group S). Induction of anesthesia: group O: Propofol 1.0 ~ 2.0 mg/kg, Oxycodone 0.3 mg/kg, Vecuronium 0.1 mg/kg. Group S: Propofol 1.0 ~ 2.0 mg/kg, Sufentanil 0.3 μg/kg and Vecuronium 0.1 mg/kg. The value of HR, SBP, DBP of the two groups were recorded in the operation room (T0), after anesthesia induction (T1), 1 min after insertion laryngeal mask (T2), the instant of pneumoperitoneum establishment (T3), separation of the gallbladder (T4), the time of wake up (T5), leave the recovery room (T6). The numeric pain rating scale (NRS) were recorded at T4, T5, 4 hours later (T7), 8 hours later (T8), one day later (T9). Then recorded the wake time and additional analgetic cases. Recorded the adverse reactions. Results The average HR, SBP and DBP fluctuations in the two groups were not more than 20.0 % of the basal values. There was no significant difference in wake time between the two groups. There were 11 cases of patients, the NRS>4, in Sufentanil group requires additional analgesics after they wake up, more than Oxycodone group (P = 0.040). The NRS score was lower in Oxycodone group than group S in T5, T7, T8, T9, but they had no statistically significant difference. There was no significant difference in adverse reactions between the two groups. Conclusion 0.3 mg/kg Oxycodone and 0.3 μg/kg Sufentanil for anesthesia induction of LC, the anesthesia and analgesia effect is good, can satisfy the clinical anesthesia and postoperative analgesic requirements. The analgesic effect of 0.3 mg/kg Oxycodone may be comparable or better than 0.3 μg/kg Sufentanil.
