Objective:To explore the effects of electroacupuncture(EA)on rats with chronic unpredictable mild stress(CUMS)-induced depression and proteins related to endoplasmic reticulum stress(ERS). Methods:Thirty-two Sprague-Dawley rats were randomly divided into a control group,a CUMS group,an escitalopram(ESC)group,and an EA group.Except for the control group,rats in other groups were exposed to CUMS.From the 1st day of modeling,the EA group was treated with EA at Baihui(GV20)and Yintang(GV29)every day,15 min each time;the ESC group was given intragastric intervention[ESC 10 mg/(kg·bw)every day],both for 28 d.Body mass measurement,open field test(OFT),and sucrose preference test(SPT)in each group were performed before(day 0)and after experiment(day 28)to record body mass growth,sugar preference index,and total distance and duration of central area in OFT.The protein expression levels of glucose-regulated protein 78(GRP78),caspase-12,and C/EBP homologous protein(CHOP)in the hippocampus and frontal cortex were detected by stain-free total protein normalization method of Western blotting.Meanwhile,the TdT-mediated dUTP-biotin nick end labeling assay was performed to determine the percentage of cell death in the frontal cortex. Results:After EA at Baihui(GV20)and Yintang(GV29),the body mass growth,sugar preference index,and total distance and duration of central area in OFT were effectively improved(P<0.05 or P<0.01);compared with the CUMS group,the expression levels of GRP78 and CHOP in the hippocampus,and caspase-12 and CHOP in the prefrontal cortex of rats were significantly reduced(P<0.05),and the apoptosis rate of cells in the prefrontal cortex decreased significantly(P<0.05). Conclusion:EA at Baihui(GV20)and Yintang(GV29)can significantly mitigate behavioral deficits of rats with CUMS-induced depression.The mechanism may be related to adjusting the ERS and inhibiting cell apoptosis.

Objective To investigate the prevalence of year-round respiratory viral infection in children with lower respiratory tract infection (LRTI), and the relationship between respiratory viral infection and allergen sensitization in exacerbating asthma. Methods A total of 231 hospitalized children with acute LRTI were investigated from May 2013 to April 2014. The 5 most common respiratory viruses were isolated from nasopharyngeal aspirate using multiplex reverse transcription-polymerase chain reaction, including respiratory syncytial virus (RSV), adenovirus (AV), parainfluenza virus (PIV), influenza virus (IFV) and rhinovirus (RV). Atopic sensitization was defined if more than 1 serum specific immunoglobulin E level measured using immunofluorescence experiment was over 0.35 IU/mL. Results RSV was the most common pathogen of bronchiolitis in hospitalized children through the year. RV or IFV infections were more prevalent in asthma exacerbations compared to other LRTIs. AV was more likely to cause pneumonia. RV and IFV were associated with asthma exacerbations in children with atopic sensitization, but not in nonatopic children. Conclusion RV and IFV are associated with hospitalization for asthma exacerbation in children with atopic sensitization.

BACKGROUND:Some studies have shown that hyperlipidemia can lead to osteoporosis in rats, and exercise can increase the bone mineral density of rats. But the effect of short-time exercise on the bone mineral density of hyperlipdemia induced osteoporosis male rats is unclear yet.
OBJECTIVE:To investigate the effect of short-time middle-load treadmil exercise on the bone mineral density of hyperlipidemia male rats.
METHODS:Twenty-six male Sprague Dawley rats were randomly divided into three groups:control group (n=8), hyperlipidemia group (n=9) and exercise intervention group (n=9). The rats in the control group were fed with normal diet, and the rats in the other two groups were fed with high-fat diet and lasted for 4 weeks to establish the hyperlipidemia models. The rats in the exercise intervention group received treadmil exercise 5 days per week for 4 weeks according to the fol owing schedule:15 m/min for 15 minutes in the 1st week, 15 m/min for 20 minutes in the 2nd week, and then 20 m/min for 20 minutes in the last 2 weeks. Slope grade of the treadmil was adjusted at 0°. At the end of experiment, the rats were sacrificed, and the bone mineral density of the right femur, the morphological change of tibia, the level of plasma alkaline phosphates and calcium content were examined.
RESULTS AND CONCLUSION:Compared with the control group, the distal femur bone mineral density in hyperlipidemia group was significantly decreased (P<0.05);histological analysis of the proximal tibia showed thinning and loss of bony trabeculae arrangement, the gap was widened, and a large amount of fat cel s infiltration or integration into vacuoles in the marrow was observed, the plasma alkaline phosphates was significantly increased (P<0.01). Compared with the hyperlipidemia group, distal femur bone mineral density in the exercise intervention group was increased (P<0.05). After adjust body weight, the whole femur bone mineral density was significantly greater in exercise intervention group compared to hyperlipidemia group (P<0.05). The histological analysis of the proximal tibia showed that the spaces of bone trabeculae decreased and the structure of bone trabeculae compacted, the alkaline phosphates activities were increased (P<0.01). There were no significant differences in serum calcium and phosphates levels between groups. The results show that short-time middle-load treadmil exercise can increase the bone mineral density of hyperlipidemia male rats.
