ObjectiveTo research a way to verify whether the stomach duct is misplaced into the trachea.MethodsThe air pressure of the stomach duct placed in the stomach or in the trachea were measured using a water bottle.ResultsThe air pressure of the stomach duct was (1±0.45)cmH2O When it was put in the stomach, and was (7±2.03)cmH2O when it was put in the trachea(P<0.01).ConclusionsWhen it is impossible to draw out acerbic substances from the stomach to verify whether the stomach duct is placed in the stomach or misplaced in the trachea, measure the air pressure stomach duct by a water bottle can be used as substitute, which is reliable and convenient.

Aim To investigate the changes of intracellular calcium in primary cultured neurons after fluid percussion injury under the effects of cerebrolysin.Methods The neurons of rats were divided into: normal group,FPI group and cerebrolysin group(0 h and 1 h treatment after fluid percussion injury(FPI)).The intracellular calcium([Ca2+]i) at rats neurons in 24 h and 48 h postinjury were measured by using the laser scanning confocal microscope under calcium fluorescent indicator Fluo-3/AM.Results The [Ca2+]i at rats neurons were markedly increased after 24 h postinjury compared with normal neurons and maintained the higher level after 48 h.Cerebrolysin,whenever added at 0h or 1h after FBI,could significantly decrease the rise of [Ca2+]i on 24 h postinjury,which only happened in 48 h postinjury by 1 h treatment after FPI.Conclusion Cerebrolysin has the protective effects on primary cultured rat cortical neurons of rats and has the time-window treatment.

Objective To investigate the effect of taurine transporter in the process of protection of brain edema in rats with severe traumatic head injury. Methods A total of 24 Male Sprague-Dawley rats were randomly divided into 4 groups. Except the control rats (Group Sham), all other three groups were subjected to lateral fluid percussion head injury. The TBI (Traumatic brain injury) models (Group TBI) and surgical control rats (Group Sham) were injected with saline through caudal vein after surgery, while the Taurine prevention and Taurine treatment models (Group Pre Tau and Group Tau) were injected with 120 g/L taurine solution before or after surgeries respectively. Water content in each brain, mRNA and protein expres?sion of aquaporin 4 and taurine transporter in the injured rat brain hemispheres were all evaluated over the time course of the study (7 d) in each group. Results Compared with rats in Group Sham, water content in each brain increase, mRNA tran?scription and protein expression of AQP4 were both up regulated but the mRNA transcription and protein expression of TauT were both down-regulated in rats in TBI group. Compared with rats in TBI group, brain water content, mRNA transcription and protein expression of AQP4 all decrease while mRNA transcription and protein expression of TauT all increase in rats in Pre tau and Tau groups. There is no statistical difference of TauT expression between rats in pre-tau group and Tau group. Conclusion Taurine exert its neuron protection role through draining water content from brain and down regulating expres?sion of AQP4 but rising expression of TauT after TBI.

ObjectiveTo investigate the human resources arrangement of rehabilitation wards in general hospital.MethodsAll works of the nurses in a rehabilitation ward within 7 days were recorded with data of average man hour of Taiwan's Hospital as the standards, the daily working hours of the related number of the nurses were calculated correctly on the missing items.Resultsthe ratio of beds to nurses was 1∶0.45, the work consumed the longest time was transfusion, others followed were medical observation, distribution of medicines, prevention of bedsore, change of bed sheets and health education and so on.ConclusionThe number of hours of rehabilitation care is to be increased; it will be more reasonable to arrange rehabilitation care training in the evenings.

目的探讨康复患者使用经外周置入中心静脉导管(PICC)的可行性。方法对康复组16例住院患者行PICC,并与非康复组行PICC的12例患者进行对照观察,分别观察留管时间、局部症状、全身症状等。结果康复组与非康复组的留管时间、局部症状、全身症状无显著性差异。结论康复治疗活动对PICC的留管时间等无影响,PICC对康复治疗也无影响,进行康复治疗的患者可行PICC。

Aim To study the apoptosis effect of cucurbitacin Ⅱa on non-small cell lung cancer cell lines NCI-H460 and A549 and its underlying mechanism.Methods Cell viability was assessed by CCK-8 assay.The apoptosis effect and cell cycle arrest were detected by Flow cytometry.Western blot was employed to detect the related protein.Results The proliferation of lung cancer cell lines NCI-H460 and A549 was inhibited by CuⅡa, which showed cytotoxic activity with IC50 values of 224.9 nmol·L-1 and 108.3 nmol·L-1 against NCI-H460 and A549 respectively.CuⅡa induced the cells apoptosis and cell cycle arrest at G2/M phase.The results of Western blot showed CuⅡa inhibited the phosphorylation of STAT3 and Cofilin in a dose-dependent manner.Further, CuⅡa inhibited the phosphorylation of Aurora A, in line with the important characteristics of anti-tumor effect of Aurora A kinase inhibitor with blocking cells in the G2/M phase.Conclusion CuⅡa has obvious anti-tumor effect against non-small cell lung cancer, which suggests its value as a lead compound for lung cell carcinoma.

BACKGROUND:The studies have shown that the mesenchymal stem cel s derived from bone marrow and umbilical cord can be continuously cultured in vitro, and maintain the characteristics of stem cel s. The mesenchymal stem cel s can differentiate into hepatocyte-like cel s after“cocktail”induction by various cytokines. OBJECTIVE:To further identify whether umbilical cord-derived mesenchymal stem cel s in vitro co-cultured with normal hepatocytes can differentiate into hepatocyte-like cel s, and to investigate the differentiation method. METHODS:Mesenchymal stem cel s were isolated from human umbilical cord with adherent method, and the surface markers of umbilical cord-derived mesenchymal stem cel s were detected with flow cytometry. The umbilical cord-derived mesenchymal stem cel s were co-cultured with liver LO2 cel s without adding exogenous inducers. The expressions of alpha-fetoprotein, albumin and human cytokeratin 19 mRNA of hepatocyte specific markers were detected with reverse transcription PCR at 7, 14 and 21 days after culture, and periodic acid-Schiff staining was used to identify the functions. RESULTS AND CONCLUSION:Mesenchymal stem cel s could isolated from human umbilical cord successful y, showing fibroblastic morphology and adherent cel characterization. Among these cel s, 96.02%cel s were CD29 positive cel s and 96.6%cel s were CD105 positive cel s. The percentage of CD34 negative cel s was 99.65%. The percentage of CD105+CD29+double positive cel s was 94.84%. The mRNA of alpha-fetoprotein was found on the 7th day after co-cultured with LO2 cel s, and the mRNA of albumin and human cytokeratin 19 were found on the 14th day. After co-cultured for 21 days, the alpha-fetoprotein mRNA could not be observed in the co-culture group. The expressions of albumin and human cytokeratin 19 were increased at 14 days. After co-cultured for 21 days, the glycogen staining was positive. Umbilical cord-derived mesenchymal stem cel s can differentiate into hepatocyte-like cel s after co-cultured with normal hepatocytes.

Chronic obstructive pulmonary disease (COPD) is a preventable and treatable common chronic airway disease. As the gatekeeper of health care, general practitioners should play a key roles in prevention and management of COPD; however, the ability of COPD prevention and management is generally limited among general practitioners, so that the training for them is essential. At present there is no unified training program and standard for COPD prevention and management in China, the training contents and methods are various, and the training facilities and capacity are inadequate, particularly in grass-roots institutions, all these restrain the development of effective training. This articles reviews the status quo of COPD prevention and management training for general practitioners at home and abroad, and suggests to construct a network for chronic respiratory diseases management and a training system for primary care health workers to improve the prevention and management of COPD in China.
