Objective To investigate the myocardial remodeling and cardiac function effects of metoprolol combined Xinshuaining mixture for treating chronic heart failure.Methods One hundred and seventy patients with chronic heart failure was equally divided into treatment group and control group of 85 cases each,accorded to the random principle of parallelism,both groups were given conventional treatment based on metoprolol,the treatment group was added Xinshuaining mixture.Results After treatment,the effective rate in the treatment group was 95.3 ％(81/85),so that was 81.2％(69/85) in the control group,there was significant difference (P ＜ 0.05).After treatment,the level of left ventricular end-systolic volume (LVESV),left ventricular end-diastolic volume (LVEDV),heart rate (HR) in treatment group were significantly lower than those in control group [(41.36 ±7.11) ml/m2 vs.(44.32 ±6.26) ml/m2,(46.28 ± 7.56) ml/m2 vs.(55.69 ± 8.12) ml/m2,(72.25 ± 3.62) bpm vs.(78.36 ± 3.44) bpm],while the level of left ventricular ejection fraction (LVEF) and 6-minute walk test distance were significantly higher [(56.48 ±8.00)％ vs.(35.16 ± 8.21)％,(566.68 ±51.86) m vs.(476.88 ±50.99) m],there were significant differeces (P ＜ 0.05).After followed up for 3 months,the incidence of cardiac adverse reactions in treatment group was significantly lower than that in control group [3.5％ (3/85)vs.11.8％ (10/85)] (P ＜ 0.05).Conclusions Metoprolol combined Xinshuaining mixture for treating chronic heart failure can improve cardiac remodeling and heart function,thereby improve the prognosis of efficacy.While its better security should be widely applied.

BACKGROUND:During in vitro culture, dental folicle cels are easy to loss self-renewal capacity and become aging, and they are also very difficult to be purified and amplified in quantity, which limits the application of dental folicle cels in periodontal tissue engineering. OBJECTIVE:To study the osteogenic effect of immortalized rat dental folicle cels. METHODS:pSSR69-pAmpho plasmids containing SV40T-Ag were used to transfect 293 cels. Rat dental folicle cels were transfected with virus supernatant and screened by hygromycin to establish immortalized rat dental folicle cels (experimental group). Untransfected cels served as controls. RT-PCR was used to detect the osteogenic related factors (alkaline phosphatase, osteocalcin, bone morphogenetic protein 2, and Runx2) in the experimental group and control group. RESULTS AND CONCLUSION:The results showed no statistical differences between the experimental group and the control group in the expressions of alkaline phosphatase, bone morphogenetic protein 2 and Runx2 (P > 0.05). The expression of osteocalcin was significantly higher in the experimental group than the control group (P < 0.05). These findings suggest that in the late osteogenesis differentiation, immortalized rat dental folicle cels may promote the secretion of osteocalcin and then make osteoblasts early entry into the bone calcification stage.

Liver transplantation is a valid treatment option for select patients with Hepatocellular Carcinoma HCC and end-stage liver disease. However, in approximately 20% of patients, recurrent HCC is the rate-limiting factor for longterm survival. Despite identification of clinical parameters that may stratify patients at high risk and exhaustive preoperative staging, cancer recurrence is likely the result of microscopic extrahepatic disease. With a desperate donor organ shortage, locoregional ablation techniques and resection are being employed in patients on the waiting list to serve as a bridge to OLT. Further more, some have advocated aggressive surgical resection of isolated metastasis in both the liver and extrahepatic viscera. Whether these creative strategies confer a survival advantage is unknown, requiring longterm follow-up to determine their efficacy.

Objective To explore the effects of vecuronium bromide within 24 hours in severe bronchial asthma with acute attack with breathing machine in conventional sedatio.Methods Prospective study,double-blind randomized standard control,where 46 cases of patients of severe bronchial asthma with acute attack transferred to ICU using breathing machine in this year were randomly divided into the vecuronium bromide group (muscle relaxant group) and conventional sedation group (normal group) according to medical record number; Two groups of sample compositions were compared by x test,using two independent samples of t test to compare the effects the treatment and prognosis.Results After mechanical ventilation for 15min and 1-3h in muscle relaxant group,patients' vital signs were statistically analyzed,including respiration; Blood gas analysis parameters were as follows:pH,PaO2,PaCO2,SpO2 of these were improved compared with those in the conventional group (P ＜ 0.05) with statistically significant differences;Compared with the conventional group,in the muscle relaxant group,the retention time in ICU (146.20 ± 17.92) hours,(214.15 ± 22.21) hours,the using time of breathing machine (125.93 ± 16.23) hours,(192.89 ± 22.60) hours,and the dosage of glucocorticoid (2.61 ± 0.17) mg · kg-1 · d-1,(3.55 ± 0.26) mg · kg-1 · d-1,anticholinergic agent(6.25 ±0.51) μg · kg-1 · d-1,(10.64 ±0.75) μg · kg-1 · d-1 and β2 adrenergic receptor agonist (0.06 ±0.01)mg · kg-1 · d-1,(0.15 ±0.04)mg · kg-1 · d-1 were all reduced (all P ＜0.05) with statistically significant differences;The patients were smoothly transferred out of ICU,without the adverse events of mechanical ventilation and cardiovascular diseases.Conclusion The use of vecuronium bromide made the patients with severe bronchial asthma in routine sedation use of breathing machine rapidly correct the clinical symptoms and improve the off-period prognosis.

Bronchogenic cysts( BC) is a congenital malformation of the lung which is common in chil-dren and adolescents. Because the disease is rare and not characteristic in symptom,sign and imaging,it can be easily misdiagnosed. It is still difficult to improve the rate of correct and early diagnosis. This article reviewes the research progress of the occurrence,symptom and management of BC.

0.05).Conclusion The therapeutic mechanism of AEP of Chinese herbal medicine for asthma may be related with the inhibition of EOS infiltration,the decrease of peripheral IL-4 content and the increase of IFN-?.

OBJECTIVE:To establish RP-HPLC combined with solid phase extraction method to determine the plasma concentration of lansoprazole.METHODS:The sample was extracted by solid phase extraction in darkness.RP-HPLC was applied using Venusil XBP-C18(200 mm?4.6 mm,5 ?m) column.The mobile phase consisted of acetonitrile-water(32:68,pH value adjusted to 7.6 with 1% ammonia water) and flow rate was 1.0 mL?min-1.The detection wavelength was set at 284 nm and column temperature was set at room temperature.RESULTS:The linear range of lansoprazole was 10～2 500 ng?mL-1(r=0.999 9) with mean recovery of 100.93%.The RSD of intra-day and inter-day were both less than 10%.CONCLUSION:The method is sensitive,convenient and rapid for the determination of lansoprazole concentration in plasma.
