Objective To compare the efficacy and safety of caffeine combined with humidified high-flow nasal cannula(HHHFNC) and nasal continuous positive airway pressure(nCPAP) on the treatment of apnea in very low birth weight (VLBW) preterm infants.Methods Totally 80 VLBW preterm infants with neonatal apnea,who were enrolled in the NICU of Hebei Province Children Hospital from September 2013 to March 2014,were randomly assigned to either HHHFNC group(39 cases) or nCPAP group(41 cases) according to respiratory support mode by random number table method,both groups were given caffeine.The incidence of severe apnea,incidence of reintubation,oxygen exposure time,duration of non-invasive ventilation time,feeding conditions and incidence of adverse events were compared.Results There were no significant differences in male/female ratio,gestational age,age at randomization and birth weight between the two groups(P ＞0.05).There were no significant differences in the incidence of severe apnea[15.4％ (6/39) vs 12.2 ％ (5/41)],incidence of reintubation [17.9 ％ (7/39) vs 19.5 ％ (8/41)],oxygen exposure time [(183.1 ± 31.2) h vs (175.9 ± 32.1) h],duration of non-invasive ventilation time [(163.3 ± 25.1) h v s (153.0 ± 26.2) h] between the two groups (P ＞ 0.05).The occurrence of abdominal distention [7.7 ％ (3/39) vs 24.4％ (10/41)],nasal trauma[2.6％ (1/39) vs 19.5 ％ (8/41)],head shaping [0.0％ (0/39)vs 29.3％ (12/41)] during treatment were lower in HHHFNC group than those of nCPAP group (P ＜ 0.05).Age began feeding was earlier in HHHFNC group than nCPAP group [(67.5 ± 19.1) h vs (96.3 ± 18.7) h,P ＜ 0.05],and day to full oral feeding was reduced in HHHFNC group than nCPAP group [(346.8±28.6) h vs (371.0 ±29.4),P ＜0.05].Conclusion HHHFNC combined with caffeine is effective on the treatment of apnea in VLBW preterm infants,and easier to make newborn tolerated.HHHFNC is an effective non-invasive respiratory support mode with few side effects.

[Objective] To discuss the therapeutic effect of different methods in the treatment of intertrochanteric femur fracture. [Methods]Totally 118 middle aged or old patients with intertrochanteric femur fracture were fixed with dynamic hip screw (DHS), Gamma nail or PFNA.[Results]Totally 112 cases were followed up, and the average time was 16 months, in those 45 patients were fixed with DHS: 29 were excellent, 11 cases were good, and 5 were poor, and the excellent to good rate was 88.9%; 36 patients were treated with Gamma nail, and the excellent, good, poor results were 28, 2, 1, respectively, and the excellent to good rate was 96.8%; 36 patients were fixed with PFNA, and the excellent, good, poor results were 29, 6, 1, respectively. The differences were significant (P=0.02, analyzed by Logistic regression with SPSS software). The excellent and good superiority of Gamma nail and PFNA were 5.1552 and 2.3726 times compared to DHS, and there was significant differences between the groups.[Conclusion]Surgical treatment of intertrochanteric femur fracture can improve the functional recovery and reduce the complication incidence, and PFNA fixing method can shorten the operative time, reduce the bleeding and the therapeutic effect is reliable, and suitable for old patients combined with osteoporosis.

Objective:To establish a method for the determination of antioxygen 1178 in 5-layer co-extrusion bags used for infu-sion. Methods:A Uitimat XB-C8 (250 mm × 4. 6 mm,5μm) column was used,the mobile phase was methanol-water with gradient elu-tion, the flow rate was 1. 0 ml·min-1 ,the detection wavelength was 223 nm,the column temperature was 35℃ and the injection vol-ume was 20 μl. Results:The concentration of antioxygen 1178 had the linear relationship within the range of 1. 64-205. 10 μg·ml-1 (r=0. 999 9),and the average recovery was 92. 05% (RSD=1. 94%, n=9). Conclusion:The method is accurate,stable and spe-cific,and can be used to determine antioxygen 1178 in 5-layer co-extrusion bags used for infusion.

Objective To investigate the influence of ginsenoside Rgl on the proliferation of neural stem cells in adult rats with fo- cal cerebral ischemia,and to explore the possible mechanism of ginsenoside Rg1 in brain protection and anti-aging action.Methods The animal model of left middle cerebral artery occlusion(MCAO)was reproduced in adult male Wistar rats.The thymidine analog bromode- oxyuridine(BrdU)was administered intraperitoneally(50mg/kg,Sigma,USA)every four hours for four times before executing the ani- mals to label the proliferating cells.By the employment of immunohistochemical single staining and double-immunofluorescence technique, the number of BrdU immunoreacted nuclei in the subventricular zone(SVZ),the number of nestin positive cells in the subgranular zone (SGZ)as well as the nestin/BrdU double-labeled positive cells were counted.The effect of ginsenoside Rg1 on the immunoreactivity for BrdU,nestin and nestin/BrdU at 1d,3d,7d and 14d after focal cerebral ischemia were also observed to compare with that of controls,Re- sults The immunoreacted cells of BrdU,nestin and nestin/BrdU were seen in SVZ and SGZ in the hippocampus following focal cerebral ischemia.The number of BrdU,nestin-positive cells and the double-labeled positive cells all reached the peak on 7d and decreased on 14d after MCAO,and the expressions markedly increased after the rats were given ginsenoside Rg1,compared with the control(P

Objective To explore the prevalence and relationship of urinary incontinence and depression among elderly female patients.Methods A total of 118 female patients older than 60 years old were interviewed face to face.The prevalence of urinary incontinence and depression were estimated using the International Consultation on Incontinence Questionnaire Urinary Incontinence Short Form-Chinese (ICIQ-SF-Chinese) and Geriatric Depression Scale-15 (GDS-15).Linear regression and Spearman correlation were used to identify the relationship between urinary incontinence and depression.Results Urinary incontinence was found in 27.1％ (32/118),and depression was in 39.0％ (46/118) of the survey population.Urinary incontinence with depression was found in 13.6％ (16/118) of the overall population.Urinary incontinence was positively correlated with depression,r=0.211,P＜0.05.The frequency of entertainment and urinary incontinence were significantly related to depression symptoms,P＜0.05.Conclusions Urinary incontinence appears to possess an additive effect on incidence of depression,which seriously affects both physical and mental health of patients.Clinicians should give patients health education and intervention measures at early stage.

Calcium/calmodulin-dependent protein kinaseⅡ (CaMKⅡ) has multiple functions, which made it play a central role in cardiovascular disease. Especially it activates numerous downstream targets in various signaling pathways that promotes vascular disease, heart failure, myocardial hypertrophy and arrhythmias. CaMKⅡcan impact calcium balance and increase calcium leak in myocardial cell via phosphorylating L type calcium channel, Ryanodine receptor (RyR 2) and phos?pholamban (PLN), and regulate ATP sensitive potassium current (IKATP) and late sodium current by affecting sodium channels and potassium channels. In addition, It can directly regulate transcription via activating the silk crack the original activated protein kinases (MAPKs) and acetylation enzyme (HDAC). These mechanisms have important roles in myocardial hypertro?phy, heart failure and arrhythmia. So we focus to demonstrating the structure and action mechanism of CaMKⅡto improve a new therapy of cardiovascular disease.
