Bronchiolitis is a common respiratory infective disease in children, which is caused by viruses mostly. A view that bronchiolitis is a special pattern of manifestation of asthma is accepted widely. In the past few years, many agents appeared as a inducement from bronchiolitis to asthma, such as family histoty and atopy. At the same time, the life style of infants( feeding patterns,infective frequency ,environment exposure)plays a role in this process. Studying these factors will help doctors to detect people with high risk, and supply treatment earlier.

OBJECTIVE:To determine the content of sophocarpidine in Fuyankang concentrated pill by HPLC.METHO_ DS:The loading agent of chromatographic column was amino bonded silica,the mobile phase was acetonitrile-dehydrated al?cohol-3%phosphoric acid(80∶10∶10),and the detection wavelength was220nm.RESULTS:There was a good linear rela?tionship between sample size and peak area score of sophocarpidine in the range of0.4064?g～2.0320?g,the average recovery rate was99.2%(RSD=1.6%).CONCLUSION:The established method is more accurate than TLC,and it can be used for the quality control of Fuyankang concentrated pill.

Objective: To explore the effect of the application of ICQ technology in constructing a harmonious environment for nursing staff.Method: The Internet,support from Tencent network,ICQ technology are employed to conduct on line communication among nursing staff.Result: the Working and interpersonal connection environment is remarkably improved by the application of ICQ technology,thus it is of great significance in constructing a harmonious relation among nursing staff and enhancing medical service quality.

During cardiopulmonary resuscitation (CPR),ventilation is provided by either mouth-to-mouth or bag-mask technique,and give 12 to 20 times breaths per minute.Ventilation should deliver 8 to 10 times breaths per minute after endotracheal intubation.Compression-ventilation ratio is 30∶2 for one rescuerand 15∶2 for two rescuers.After the return of spontaneous circulation,if no spontaneous breathing or irregular,respiratory insufficiency,mechanical ventilation is required.High oxygen and excessive ventilation after CPR should be avoided.When acute lung injury or acute respiratory distress syndrome occurs after CPR,lung protective ventilation strategy is applicable.

Dendritic spines are functional protrusions on neuron dendrites and formation of excitatory synaptic sites.Dendritic spines contain a variety of cell surface receptors,actin cytoskeleton,scaffolding proteins and other components,which regulate the growth of dendritic spines maturation and structure.Multiple components within dendritic spines not only have effects on expression of its shape and structure,but also on the function.Morphology of dendritic spines is closely related with its function.Its shape is affected by many factors in the changing process.So dendritic spine plasticity is an important aspect of synaptic function in the central nervous system,and is closely related with learning and memory function and central nervous system diseases.

ObjectiveTo obtain data related to various periods of acupuncture treatment for rat focal ischemia and reperfusion and infer the optimal time point of acupuncture treatment by examining cerebral ROCK expression on the ischemic side in different periods of acupuncture for rats with focal ischemia and reperfusion.MethodOne hundred andeighty male adult Wistar rats were enrolled and randomly allocated to blank, sham operation, model and acupuncture groups. The model and acupuncture groups were separately divided into 5 subgroups: the 6 h, 24 h, 48 h, 72 h and 2 w subgroups. There were atotal of 12 groups, 15 rats each. An animal model of focal cerebral ischemia was made using a thread occlusion method for obstructing rat right middle cerebral artery. The carotid artery was only separated in the sham operation. Materials were taken in the blank and sham operation groups on day 2 after model making. Materials were taken for examination in every subgroup of the model group at 6, 24, 48 and 72 hours and 2 weeks after model making. Materials were taken for examination after acupuncture at Baihui(GV20), Dazhui(GV14)and Zusanli (ST36)in every subgroup of the acupuncture group at 6, 24, 48 and 72 hours and 2 weeks after model making.ResultAcupuncture markedly improved neurological deficits in rats with cerebral ischemia and reperfusion. Areduction in the neurological deficit score was largest in the 6 h acupuncture group and there was a statistically significant difference compared with the other acupuncture groups (24 h, 48 h and 72 h) (P<0.05). There was no statistically significant difference in ROCK expression between the sham operation and blank groups (P>0.05). There was a statistically significant difference in ROCK expression between the model (ischemia-reperfusion 6 h, 24 h, 48 h and 72 h) and blank groups (P<0.05). ROCK expressionreached the peak value at 6 hours after ischemia and reperfusion. There was a statistically significant point-to-point difference in ROCK expression between the acupuncture (ischemia-reperfusion 6 h, 24 h, 48 h and 72 h) and model (ischemia-reperfusion 6h, 24 h, 48 h and 72 h) groups (P<0.05). ROCK expression was down-regulated most markedly in the ischemia-reperfusion 6 h acupuncture group.Conclusion Acupuncture has an inhibitory effect on Rho/Rock in a rat model of cerebral ischemia and reperfusion. Six hours after ischemia and reperfusion is the optimal time point of acupuncture treatment. Acupuncture at that time can protect and improve post-ischemic injured brain tissue to the largest extent.

Objective To observe the effects of hyperbaric oxggenation (HBO) on liver blood flow, hepatic functions and the changes of clinical manifestations in patients with chronic hepatitis. Methods Thirty two patients with chronic hepatitis (HBO group) were treated with HBOThe changes of blood flow of the right branch of portal veinin HBO group were and hepatic functions were measured. Results After HBO, hepatic functions were significantly improved, and the blood flow of the right branch of portal veinwas was increased as compared with that before the treatment(0.318?0.101 L/min vs 0.378?0.102 L/min, P

0.05 ), bacterial clearance were 100% and 90%, and adverse reaction rates were 10%(2/20)and 10.53 % ( 2/19 ), respectively. All those adverse reactions were mainly gastrointestinal tract reactions. The abnormality of laboratory inspections associated with trial drugs happened to 4 and 5 patients in two groups. The reactions were mostly light increase of aminotransferase without effect on therapy. CONCLUSION: Gatifloxacin is an antibiotic with large antimicrobial spectrum and can be recommended to treat light to moderate acute lower respiratory tract infections.

OBJECTIVE: To establish HPLC fingerprint of Compound danshen tablets.METHODS: The separation was performed on Agilent Eclipse XDB-C18(150 mm?4.6 mm,5?m) column with mobile phase consisted of acetonitrile-0.04% phosphate (gradient elution) at flow rate of 1.0 mL?min-1.Detection wavelength was set at 272 nm and column temperature was 30℃.RESULTS: Established HPLC fingerprint was distinct and reproducible.There were 8 characteristic peaks among which No.5 characteristic peaks,No.6,No.7,No.8 came from HPLC fingerprint of Salvia miltiorrhiza and No.1 characteristic peaks,No.2,No.3,No.4 came from HPLC fingerprint of Panax notoginseng.CONCLUSION: The characteristic peaks of effective parts of Compound danshen tablet mainly come from S.miltiorrhiza.The study can be used for tracing and isolation of effective part of Compound danshen tablet and establishes basis for the further development of Chinese patent drugs.
