This paper employed UPLC-Electrospray Ionization /Quadrupole-Time of Flight-Mass /Mass Spectrometry( UPLC-ESI/Q-TOF-MS/MS) to analyze the chemical constituents in the stems of Nelumbo nucifera. The stems of N. nucifera were extracted with 75% methanol, and we applied an Agilent Zorbax SB-Aq column (2.1 mm x 100 mm, 1.8 μm) to UPLC analysis with water methanol-water( containing 0.05% formic acid) in gradient as mobile phase. The eluates were then detected by ESI-Q-TOF-MS/MS. Results indicated that 22 benzylisoquinoline alkaloids were indendified. Among them, one alkaloid may be a new compound and a component was found in the Lotus for the first time. We fully identify the composition of the Lotus stems for the first time, Which could provides theoretical foundation for further study and utilization of the medicinal resources.

Objective To investigate the cognition and attitude towards the elderly family nursing among nurses and college students in Chengde, and analyze its influencing factors. Methods A total of 1000 college students and nurses in Chengde were investigated by self-designed questionnaire about their cognition and attitude to elderly family nursing. Results Nurses' cognition and attitude towards the elderly family nursing was better than nursing college students, medical students were better than non-medical students; and there was no statistical significance about their expectation for government's senior citizen service among different groups. Conclusions More attention should be paid to family members' attitudetowards the elderly home care, and should strengthen the elderly family care through various way.

According to the latest research findings on nitrogen removal in both domestic and abroad, the mechanism for simultaneous nitrification and denitrifi cation(SND)was reviewed and analyzed in various aspects including macroenviron ment and microenvironment theory as well as biology theory The works such as t he realization of SND by aerobic granular sludge, simultaneous nitrogen and phos phorus removal, which could be done in the future, were proposed

Objective To explore the application of central venous catheter(CVT) in hemodialysis.Methods The clinical data of 2 206 cases of CVT patients were analyzed retrospectively,and the catheter puncture site,the catheter indwelling time,4 weeks of blood flow rate and the incidence of catheter related infections,and so on were observed.Results Internal jugular vein in 2 033 cases,the femoral vein in 173 cases.Internal jugular vein indwelling catheter time was (40.6 ±32.7) d,the femoral vein catheter indwelling time was (22.4 ± 16.3) d,and the difference was statistically significant (P＜ 0.05).Blood flow patency rate in four weeks was of 96.4％ (1 959/2 033) indwelling catheter in internal jugular vein,which was significantly higher than that of the femoral vein in 83.2％ (144/173),and the difference was statistically significant (P ＜ 0.05).Femoral vein catheter related infection rate was 11.0％ (19/173),significantly higher than that of internal jugular vein in 3.6％ (73/2 033),the difference was statistically significant (P ＜ 0.05).Conclusion Application of CVT for hemodialysis is convenient and reliable,with low infection rate,fewer complications,operation technology level is the key to success.

OBJECTIVETo compare the therapeutic effects of peripheral facial paralysis in acute stage by different interventions and explore the better treatments of peripheral facial paralysis.

METHODSOne hundred and thirty one cases of Bell's facial paralysis were randomly divided into three groups. In acupuncture group (44 cases), Dicang (ST 4), Jiache (ST 6), Hegu (LI 4), Yangbai (GB 14) and Taiyang (EX-HN 5), etc. were applied; in electroacupuncture group (45 cases), the selection of acupoints and needling method were same as those in acupuncture group, and the electroacupuncture therapy was applied on Dicang (ST 4), Xiaguan (ST 7), Yangbai (GB 14) and Taiyang (EX-HN 5) in acute stage; in medication and acupuncture group (42 cases), Prednisone and Acyclovir were taken by oral administration, Vitamin B1 and Vitamin B12, were applied by intramuscular injection in acute stage, and acupuncture was applied by the way which was same as that in acupuncture group during quiescent and recovery stages. The curative effects were evaluated by House-Brackmann Grading Scale, and the failed rates were observed by follow-up after one and three months.

RESULTSThe cured and markedly effective rates were 79.6% (35/44), 93.4% (42/45) and 78.6% (33/42) respectively in acupuncture group, electroacupuncture group and medication and acupuncture group, and the result in electroacupuncture group was superior to those in acupuncture group and medication and acupuncture group (P < 0.05). The cured rates above tympanichord were 54.2% (13/24), 85.2% (23/27) and 48.0% (12/25) in acupuncture group, electroacupuncture group and medication and acupuncture group, and the result in electroacupuncture group was superior to those in acupuncture group and medication and acupuncture group (P < 0.01). There was no significant differences of cured rates below tympanichord among three groups (P > 0.05); and the failed rate in electroacupuncture group was much lower than those in acupuncture group and medication and acupuncture group by follow-up after one and three months (all P < 0.01).

CONCLUSIONThe peripheral facial paralysis is effectively treated by electroacupuncture in acute stage, and it suggests that electroacupuncture should be applied early during the acupuncture treatment of peripheral facial paralysis.

BACKGROUNDIt is very important to search for novel anti-ischemia/reperfusion neuroprotective drugs for prevention or treatment of cerebrovascular diseases. Icariin, the major active component of traditional Chinese herb Yinyanghuo, may have a beneficial role for neurons in cerebral ischemia/reperfusion caused by accident. However, it was not clear yet. In this study, we observed the protective effects of icariin on neurons injured by ischemia/reperfusion in vitro and in vivo and investigated its protective mechanism.

METHODSCerebral cortical neurons of Wistar rats in primary culture were studied during the different periods of oxygen-glucose deprivation and reperfusion with oxygen and glucose. Cell viability was determined by methyl thiazoleterazolium (MTT) assay. The activity of lactate dehydrogenase (LDH) leaked from neurons, cell apoptosis and the concentration of intracellular free calcium were measured respectively. On the other hand, the mice model of transient cerebral ischemia/reperfusion was made by bilateral occlusion of common carotid arteries and ischemic hypotension/reperfusion. The mice were divided into several groups at random: sham operated group, model group and icariin preventive treatment group. The changes of mice behavioral, activities of superoxide dismutase (SOD) and the content of malondialdehyde (MDA) were measured, respectively.

RESULTSTreatment with icariin (final concentration 0.25, 0.5, and 1 mg/L) during ischemia/reperfusion-mimetic incubation in vitro concentration-dependently attenuated neuronal damage with characteristics of increasing injured neuronal absorbance of MTT, decreasing LDH release, decreasing cell apoptosis, and blunting elevation of intracellular calcium concentration. And in vivo the learning and memory abilities significantly decreased, activities of SOD were diminished and MDA level increased obviously in model group, compared with that in sham operated group. But pre-treatment of model mice with icariin (10, 30 and 100 mg/kg, i.g.) significantly blunted the decrease of mice learning, memory ability and SOD activity, and markedly decreased MDA level.

CONCLUSIONSIcariin has protective effects on cerebral ischemia/reperfusion injured neurons. And decreasing cell apoptosis, preventing intracellular calcium concentration elevation and enhancing anti-oxidant capacity may contribute to its protective effects.
