OBJECTIVE To study the effect of the intervention of monitoring-training-planning(MTP) on use of antibacterials and injections for pediatric acute upper respiratory infection.METHODS In accordance with selected drug use indicators(SDUIS),the pediatric outpatient prescription of acute upper respiratory infection was selected in our hospital from Jun to Aug 2006 as the baseline,and intervented by MTP,then the investigation of post-interfervention was carried out after a month,and then re-intervention research was made,so the cycle continued.RESULTS The percentage ratio of antibacterials,and injection usage,and the average drug fee in pediatric outpatient prescription for acute upper respiratory infection in our hospital was decreased from 75.00%,61.67%,40.33% and 54.29 yuan to 7.00%,5.00%,3.00% and 39.16 yuan,respectively after four rounds of MTP(all P

Objective:To investigate the effect of DNA vaccine expressed Helicobacter pylori(Hp) oipA on protecting against Hp infection.Methods:The ORFs of Hp oipA had been inserted into the eukaryotic expressing vector pVAX1 and SGC-7901 cells had been transfected with recombinant plasmid pVAX1-oipA. The expression of oipA had been detected by RT-PCR and ELISA. After extracted and purified, pVAX1-oipA had been injected into BALB/c mice through muscles of right leg one time each week for three weeks(100 ?g each mouse). pVAX1 blank and normal saline had been used as the control groups. Titer of antibodies had been detected by ELISA two months after the last immunization. Based on the confirmation of immunological response in the pVAX1 groups, mice had been given orogastric challenged with live Hp Sydney strain three times(0.5?108/0.5 ml each mouse). Four weeks after challenge, mice had been sacrificed. Histological change and the colonization of Hp in the gastric mucosa had been detected by urease test, the culture of Hp, and electronic microscopy.Results:SGC-7901 cells transfected with pVAX1-oipA had expressed corresponding production at the level of transcription and translation. Immunized mice had been induced anti-oipA antibodies. After challenged with bacterium, as contrast to immunized mice groups injected with pVAX1-oipA, pVAX1 blank, normal saline, the positive rate of urease test of gastric mucosa was 0(0/10), 90%(9/10), 100%(5/5)respectively,the positive rate of cultures of Hp was 20%(2/10), 90%(9/10), 100%(5/5)respectively. Histological findings: the different degree of erosion had been observed in control group, but 80%(8/10)of gastric mucosa were normal in immunized mice.Conclusion:oipA DNA could induce effective immune response in protection against Hp infection.

Pronunciation obstacle is one of the characteristics of hearing and speech disabled persons. As the main organ of pronunciation,tongue plays an important role in pronunciation training. If the pronunciation visualization is applied to rehabilitation training, this can make the hearing and speech disabled persons intuitively watch the change of the tongue in the process of pronunciation, which may promote the rehabilitation training. On the basis of tongue anatomical structure and movement characteristics, the common movements of tongue in pronunciation are realized after the establishment of three-dimensional tongue muscle model and the relevant data of the tongue Xray images and electropalatography. Using this kind of visualization technology, we can help correction and rehabilitation for the hearing and speech disabled persons.

Spinal edema is a very important pathophysiological basis for secondary spinal cord injury,which affects the repair and prognosis of spinal cord injury.Aquaporin-4 is widely distributed in various organs of the body,and is highly expressed in the brain and spinal cord.Inward rectifying potassium channel 4.1 is a protein found in astrocytes of central nervous system.It interacts with aquaporins in function.Aquaporin-4 and inward rectifying potassium channel 4.1 play an important role in the formation and elimination of spinal cord edema,inhibition of glial scar formation and promotion of excitotoxic agents exclusion.The distribution and function of aquaporin-4 and inward rectifying potassium channel 4.1 in the central nervous system and their expression after spinal cord injury have multiple effects on spinal edema.Studies of aquaporin-4 and inward rectifying potassium channel 4.1 in the spinal cord may provide new ideas for the elimination and treatment of spinal edema.

Objective:To analyze the characteristic of nerve tracts in different stages of cognitive impairment caused by white matter hypertensities, applying diffusion tensor imaging-peak width of skeletonized mean diffusivity as evaluation indicator.Methods:Demographic characteristics and vascular risk factors of all subjects were recorded.Screened out 50 subjects without WMH and whose MoCA scale was more than or equal 26 points as normal control group.Then, we assessed 85 patients with WMH using the MoCA scale and clinical dementia assessment. Of 85 patients, 45 cases were divided into the normal cognition group, 23 cases were assigned into non-dementia vascular cognitive impairment group, and 17 cases into the vascular dementia group.The diffusion tensor imaging-peak width of skeletonized mean diffusivity marking method was used to compare the integrity of white matter fibers in WMH patients with varying degrees of cognitive impairment and normal control group.Results:The difference of PSMD among the four groups was statistically significant(CN group: 3.558±0.157, VCIND group: 4.128±0.222, VaD group: 5.469±0.000, NC group: 2.612±0.105, F=42.479, P<0.05). PSMD in WMH groups were higher than that in NC group (all P<0.05). There was no significant difference between WMH-VCIND group and WMH-CN group ( P=0.067). The PSMD of WMH-VAD group was higher than that of WMH-CN group and WMH-VCIND group (both P<0.05). Conclusion:PSMD can accurately detect white matter fiber damage caused by WMH.The degree of WMH combined cognitive decline was not completely consistent with the degree of PSMD increase.Compared with the cases with normal WMH cognition, PSMD was not significantly increased when WMH was combined with VCIND, while PSMD was significantly increased when WMH was combined with VaD.DTI-PSMD value as imaging marker can provide objective basis for clinical diagnosis of WMH-VaD.

Objective: To evaluate the efficacy and safety of oseltamivir in the treatment of suspected influenza in children. Method: A multicenter, randomized and open-label trial was conducted among 229 individuals with suspected influenza which were collected from the clinic of 5 hospitals in Guangdong province (Guangzhou Women and Children′s Medical Center, Shenzhen Baoan District Maternity and Child Care Service Center, the Second Affiliated Hospital of Shantou University Medical College, Dongguan Maternity and Child Care Service Centre, Yuexiu District Children′s Hospital of Guangzhou) from April to July 2015. They were randomized either to oseltamivir group (oseltamivir 30-75 mg, twice daily for 5 days) or control group who were given symptom relief medicines for 5 days. Result: No significant difference was found between two groups in influenza symptoms of the patients before the treatment(P>0.05). Altogether 229 individuals (114 in oseltamivir group, 115 in control group) were analyzed for efficacy, in which 73 individuals (42 oseltamivir, 31 control), 31.9%, were identified as influenza-infected through laboratory test. No significant difference was found between the two groups in the duration of fever although shortened. In the 229 individuals , the cumulative alleviation proportion between oseltamivir and control group was not significantly different (P>0.05): the median duration of illness was 69.9 hours (95% CI 65.3-91.5) in oseltamivir group and 75.4 hours (95%CI 63.9-91. 7) in control group; the median duration of fever was 40.4 hours (95%CI 31.5-53.4) in oseltamivir group and 44.0 hours (95%CI 33.2-50.0) in control group. In the 73 individuals, the cumulative alleviation proportion between oseltamivir and control group was significantly different (P<0.05). The median duration of illness was 61.2 hours (95%CI 48.0-121. 0) in oseltamivir group, being significantly shorter than that of 116.0 hours (95%CI 91.5-175.0) in control group. But it was not significantly different that the median duration of fever was 32.8 hours (95%CI 24.0-47.0 ) in oseltamivir group and 55.8 hours (95%CI 43.6-78.3 ) in control group (P>0.05). And the median duration of fever in 60 individuals (38 oseltamivir, 22 control) was significantly different between two groups(P<0.05), who had finished a course of taking oseltamivir in the 73 individuals, 34.8 hours (95%CI 24.0-48.5 ) in oseltamivir group being significantly shorter than that of 53.3 hours (95%CI 43.6-104.0 ) in control group. There was certain difference in side effects rate between the two groups (oseltamivir 10%, control 2%, P<0.05). The main side-effects were gastrointestinal symptoms (stomachache, diarrhea, poor appetite, vomiting). Conclusion The duration of illness and fever in suspected influenza patients treated with oseltamivir was shorter than those in the patients treated with no oseltamivir, the difference was not statistically significant, when 31.9% was confirmed with positive result of virus test in suspected influenza in children. But in these patients with positive result of virus test, the duration of illness was significantly shortened with treatment with oseltamivir as compared with no treatment with oseltamivir, and it would be better if full oseltamivir course was completed for reducing the duration of fever. Oseltamivir treatment was safe with mild side effects.
